Electronic component pick-up unit and its application operation equipment

The invention provides an electronic component pick-up unit capable of reducing the component configuration of the pick-up unit and ensuring that the pick-and-place member absorbs the displacement of the electronic component and is surely actuated and reset, thereby saving cost and improving the use efficiency.

Nowadays, the pick-up unit with the pick-and-place unit is applied to different working equipment for picking up and transferring electronic components. Referring to FIG. 1 , it is a pick-up unit 10 of a conventional shifting mechanism applied to a working device. The picking unit 10 is provided with a body 11 of a connecting member 20 mounted on a loading mechanism (not shown), and can be displaced in the first, second and third directions (such as X, Y, Z directions). The body 11 The internal system is provided with a housing-shaped receiving hole 111, and a suction port 112 communicating with the receiving hole 111 is formed at a side thereof. The air suction port 112 is connected to the air suction pipe 12, and the air suction pipe 12 is connected to an air suction device ( The pick-and-place member 13 is mounted on the bottom of the receiving hole 111 of the main body 11. The pick-and-place member 13 is provided with a suction nozzle 131 on the bottom surface thereof, and a receiving portion is connected to the suction nozzle 131 and the body 11. The vent 132 of the hole 111 is a set of springs 14 disposed on the outside of the pick-and-place member 13. One end of the hole is abutted against the top surface of the receiving hole 111 of the body 11, and the other end is abutted against the outer ring surface of the pick-and-place member 13. The rim 133 is disposed, and the elastic ejector pin-holding member 13 is displaced in the accommodating hole 111 of the body 11 in the third direction, and the second component is assembled outside the pick-and-place member 13. The O-rings 151 and 152 on the inner surface of the receiving hole 111 of the main body 11 are attached to the inner surface of the receiving hole 111 of the main body 11 to prevent gas leakage, and a limit is placed on the pick-and-place member 13. The position rod 16 and the limit rod 16 are disposed on the body 11 The groove 113 is configured to limit the displacement of the pick-and-place member 13; in use, the connecting member 20 of the moving mechanism drives the pick-up unit 10 to be displaced in the third direction, so that the pick-up member of the pick-up unit 10 picks up the nozzle 13 The pressing unit 12 is pressed against the electronic component. The picking unit 10 can extract the air in the receiving hole 111 through the air extracting port 112 of the body 11 through the air extracting pipe 12 connected to the air extracting device, and then pass through the air vent 132 of the pick-and-place member 13. The air at the suction nozzle 131 is extracted, so that the suction nozzle 131 has suction force to adsorb the electronic component, and the pick-up member 13 is pushed by the reaction force of the electronic component to compress the spring 14 for upward displacement in the third direction, and the electronic component is taken out. After that, since the electronic component is not used as the force pushing and pushing member 13, the pick-up member 13 can be reset by the resetting force of the spring 14 to be displaced downward in the third direction, thereby transferring the electronic component to the next device. At the office.

However, the pick-up unit 10 can quickly perform the third-direction displacement reset when the pick-up member 13 is pushed by the reaction force of the electronic component, and the spring 14 is placed on the pick-and-place member 13, which causes cumbersome and time-consuming The housing 11 is formed into a housing-shaped receiving hole 111. The housing hole 111 is not easy to manufacture and has low precision. The outer edge of the pick-and-place member 13 must be processed to form a retaining edge 133 for receiving the spring 14, thereby increasing the component. The cost and the inconvenience are inconvenient; and since the air suction pipe 12 is connected to the air suction port 112 of the main body 11, in order to prevent the air vent 132 of the pick-and-place member 13 from being deflated, it is necessary to add two at the upper and lower portions of the vent 132 of the pick-and-place member 13. The O-rings 151 and 152 for preventing leakage are more inconvenient in terms of component cost and assembly time; and the outer ring faces of the two O-rings 151 and 152 are tightly adhered to the inner wall surface of the receiving hole 111 of the body 11 to prevent leakage. However, when the pick-and-place member 13 is displaced in the third direction, a large frictional force is generated between the two O-rings 151 and 152 and the accommodating hole 111, and it is not easy to quickly perform the third-direction retraction displacement or the convex-recession reset. , causing the lack of accuracy in the handling of electronic components; When the reaction force of the electronic component is pushed up, and the compression spring 14 is displaced upward in the third direction, the pick-up member 13 will have its own weight, the reaction force of the spring 14 and the two O-rings 151, 15 The large downward pressure formed by the frictional force of 2 is pressed against the electronic component, so that the electronic component is damaged by being subjected to excessive pressure, which causes the loss of the electronic component to be easily damaged; further, when the pickup unit 10 is of the O-type When the ring 151, 152 is worn or deformed for a period of time and is unable to be in close contact with the inner wall surface of the receiving hole 111 of the body 11, the air vent 132 of the pick-and-place member 13 is deflated, so that the nozzle 131 of the pick-up member 13 is removed. The electronic components cannot be vacuumed, which affects the shifting operation and causes the inconvenience of work.
