S6, referring to FIG. 9, the pressing head 32 is driven to descend by the pressing head lifting mechanism 33, the shell preform 1 is pressed on the basin frame 2, and the pressure is maintained until the glue is solidified.

S7, referring to fig. 12, the connection plate 11 on the housing preform 1 is punched or cut out to obtain a final assembly of the half housing and the tub 2.

The application firstly processes the shell preformed piece 1, the two half shells 12 are connected into an integral structure through the connecting plate 11, and then the integral glue is applied to the basin frame 2, and as the basin frame 2 and the shell preformed piece 1 are both in a frustum shape and are in front surface mounting when being contacted up and down, the basin frame 2 and the half shells 12 are positioned by the positioning block 31, the pasting precision is high, and the two half shells 12 are pasted at one time, and the efficiency is high; the pressing head 32 is used for pressing the basin frame 2 and the shell preformed piece 1, so that the bonding quality of glue can be improved, and as the outer surface of the positioning block 31 is matched with the inner surface of the shell 21 and the inner surface of the pressing head 32 is matched with the outer surfaces of the two half shells 12, when the pressing head 32 is pressed, the shell 21 and the half shells 12 can be well supported and cannot be pressed and deformed; after the glue is solidified, the connecting plate 11 is cut off. The assembling method of the half shell 12 and the basin frame 2 has high assembling precision, high efficiency and higher bonding quality.

Referring to fig. 3, the outer surface of the housing 21 of the basin frame 2 is provided with a plurality of first glue storage grooves 23, and the first glue storage grooves 23 respectively correspond to two ends and the middle of the half shell 12 so as to enhance local adhesion. The first glue storage groove 23 can store more glue, and the glue can form an embedded structure with the side wall of the first glue storage groove 23 after being solidified, so that the local adhesive force can be greatly increased.

Referring to fig. 5, the connection between the connection plate 11 and each half shell 12 is only three, which are respectively located at two ends and the middle of the upper edge of the half shell 12. In this way, the connecting plate 11 and the half shell 12 are stressed uniformly, the connection is reliable, the overall strength of the shell preform 1 is also sufficient, and the deformation in the bonding process and the pressing process is difficult. Since there are only three connections, the connection plate 11 can be punched out or cut out more easily in step S7. In order to further improve the removal efficiency of the connecting plate 11, a thickness halving cutting groove 13 can be formed at the connecting position between the connecting plate 11 and the two half shells 12, and the influence on the half shells 12 can be reduced due to the fact that the material at the connecting position is thinner, blanking and cutting can be easier, machining acting force and stress can be reduced in the removal process, and the effect on the half shells 12 is reduced.

Referring to fig. 3, the half shell 12 is provided with a first microphone hole 122, a corresponding position on the shell 21 of the basin frame 2 is provided with a second microphone hole 24, the diameter of the second microphone hole 24 is larger than that of the first microphone hole 122, a corresponding position of the positioning block 31 is provided with a second positioning column 312, the second positioning column 312 is a step positioning column, and the step positioning column is mutually matched with the first microphone hole 122 and the second microphone hole 24 so as to prevent the glue from blocking the first microphone hole 122 and the second microphone hole 24. The step positioning column has better strength, is not easy to deform or break, and has longer service life.

Generally, the step positioning posts should be arranged vertically so as to prevent the housing 21 of the basin stand 2 and the housing preform 1 from being placed on the positioning block 31. When the first microphone hole 122 and the second microphone hole 24 are obliquely arranged, the stepped positioning column may not completely fill the first microphone hole 122 and the second microphone hole 24, or even may not extend into the first microphone hole 122. For this reason, referring to fig. 10 and 11, the positioning and pressing fixture 3 further includes a base 36, a sliding hole 313 and a spring 34 are disposed in the positioning block 31, the second positioning column 312 is slidably disposed in the sliding hole 313, the spring 34 is used for ejecting the second positioning column 312 forward, the lower end of the second positioning column 312 further passes through the base 36 to be connected with the hanging member 35, and the hanging member 35 is pulled (a pedal manner may be adopted) to move the second positioning column 312 obliquely downward. The second positioning post 312 can extend into the first microphone hole 122 and the second microphone hole 24 when being pushed forward, and can be disengaged from the first microphone hole 122 and the second microphone hole 24 when the second positioning post 312 is retracted backward, and the assembly of the housing preform 1 and the tub 2 can be removed.

Referring to fig. 13 and 14, the housing 21 is provided with a plurality of first through holes 25, one side edge of the first through holes 25 is a narrow edge, two corresponding positions at two ends of the half-side housing 12 are provided with second through holes 123, the size of the first through holes 25 is larger than that of the second through holes 123, two side edges of the half-side housing 12 are also narrow edges, the inner surfaces of the narrow edges at two sides of the half-side housing 12 are provided with strip-shaped second glue storage grooves 124 so as to enhance local adhesion, and the narrow edges on the housing 21 are provided with chamfer angles 26 so as to increase the contact area with glue in the second glue storage grooves 124. Since many through holes may be formed in the housing 21, for example, for mounting buttons, atmosphere lamps, decorative strips, etc., when the first through hole 25 must be formed at the edge due to molding and design problems, and one side of the first through hole 25 is narrow (generally, the width is less than 2 mm), the adhesive bonding area between the housing 21 and the half shell 12 is very small, and the adhesive bonding is easy to be unstable, so that the situation of opening the adhesive occurs. Therefore, the application arranges the strip-shaped second glue storage grooves 124 on the inner surfaces of the narrow sides of the half shell 12, and arranges the chamfer 26 on the narrow sides of the shell 21, thereby increasing the contact area with the glue in the second glue storage grooves 124, and the double pipes are aligned to enhance the local (narrow side) adhesive force and increase the connection reliability of the shell 21 and the half shell 12.

Referring to fig. 3, the connection between the connection plate 11 and the two half shells 12 is in step S7, incompletely cut away, leaving 1-3mm for the snap 112 for fixing the filter screen 4. After the loudspeaker is arranged at the loudspeaker mounting hole 22 in the middle of the shell 21, the filter screen 4 is also required to be arranged to protect the loudspeaker and filter dust, the application fully excavates the value of the connecting plate 11, so that the connecting plate 11 has multiple purposes, as three connecting positions are arranged on each half shell 12, three buckles 112 are formed, the filter screen 4 is fixed by six buckles 112 which are arranged separately, the fixation is also reliable, and as the connecting position of the connecting plate 11 and the half shell 12 is provided with a thickness reducing half groove, the thickness of the buckle 112 is thinner after the connecting plate 11 is cut off, and the filter screen 4 can be forced into the buckles 112 with a certain elasticity. Not providing the catch 112 on the housing 21 also reduces the difficulty of manufacturing the housing 21.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
