Technical Field

The utility model relates to the technical field of jigs, in particular to a positioning and clamping jig for robot products.

Background Art

In the manufacturing process of modern TV panels, coating technology is a key link to achieve high-performance display. This includes multiple layers of complex spraying on TV panels, such as conductive layers, polarizing layers, multi-color filter layers, as well as protective and anti-reflective coatings. These coatings must be applied in a highly consistent and precise manner to ensure uniformity of display effects and color accuracy.

At present, TV panel production generally adopts the super-large panel size cutting method, uniformly clamping and spraying the uniform large-size TV panels, and then cutting the unsprayed edges to avoid changing the clamping fixture due to size.

However, the positioning and clamping fixtures for TV panels still have the following problems:

1. During the spraying process, the TV panel needs to be heated to speed up the drying and curing of the paint, which causes the TV panel to expand thermally and cause the surface to be scratched or broken by the limiting structure.

2. During the spraying and moving process, since the TV panel needs to be sprayed on both sides and moves along the assembly line, the TV panel is subjected to uneven force and shakes, causing the TV panel to break or break.

DETAILED DESCRIPTION

The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Fig. 1-3, a robot product positioning and clamping fixture includes a first frame 1, the first frame 1 is in the shape of a "mouth", and a plurality of limit assemblies 3 are evenly fixedly connected to the front of the first frame 1;

The limiting assembly 3 includes a first plate body 31, which is fixedly connected to the four corners of the front face of the first frame 1. The outer end of the first frame 1 is fixedly connected to a rotating shaft 32, and the rotating shaft 32 is rotatably connected to a rotating plate 33. The end of the rotating plate 33 close to the surface of the first frame 1 is fixedly connected to a frame body 34, and a spring 35 is fixedly connected inside the frame body 34. The length of the spring 35 is greater than that of the frame body 34, and the spring 35 is fixedly connected to a pressing plate 36;

The first frame 1 is fixedly connected to the second frame 2, which is also in the shape of a Chinese character "口". The second frame 2 is sleeved on the inner wall of the first frame 1, and the first frame 1 and the second frame 2 are both hollow inside.

The second frame 2 includes a frame body 25, a plurality of air holes 21 are fixedly opened on the surface of the frame body 25, a connecting groove 22 is opened at the intersection of the frame body 25 and the first frame 1, a micro pump 23 is fixedly connected to the cavity of the first frame 1, and an output end of the micro pump 23 is fixedly connected to a gas container 24;

The vertical cross section of the frame body 25 is a parallelogram, the frame body 25 is obliquely fixedly connected to the first frame 1, the thickness of the frame body 25 is smaller than the first frame 1 and the edges of the frame body 25 are fixed to the surface of the frame body 25;

The outer side of the air hole 21 is surrounded and fixedly connected with silicone rubber, and the inner end of the pressing plate 36 is also fixedly connected with a silicone rubber sheet;

A control button 4 for starting and shutting down the micro pump 23 is also fixedly connected to the surface of the first frame 1;

The first frame 1 and the second frame 2 are internally connected and airtight, and only the air hole 21 is connected to the outside;

The gas container 24 is made of a rigid material and is not affected by the increase or decrease of the gas pressure inside it;

Working principle: When in use, place the TV panel on the inclined surface of the second frame 2, then gently press the TV panel so that the TV panel fits the silicone rubber on the surface of the air hole 21, and then start the micro pump 23 through the control button 4, so that the micro pump 23 draws part of the gas inside the first frame 1 and the second frame 2 into the gas container 24, so that the air pressure inside the first frame 1 and the second frame 2 is less than the atmospheric pressure, so that the TV panel is buckled on the surface of the air hole 21 by the atmospheric pressure, and will not vibrate when moving with the assembly line and after spraying. Then press the control button 4 to turn off the micro pump 23, the gas in the gas container 24 is released, and the air pressure in the first frame 1 and the second frame 2 returns to normal, releasing the lock of the TV panel by the atmospheric pressure;

Then, the rotating shaft 32 is rotated to make the rotating plate 33 move toward the TV panel, and the pressing plate 36 is buckled on the surface of the TV panel to fix the TV panel. The TV panel enters the spraying machine, and then expands slightly after being sprayed and heated, so that the spring 35 contracts and does not press the surface of the TV panel.

Silicone rubber is an elastic, heat-resistant rubber that protects the surface of the TV panel while preventing it from being damaged by heat melting due to insufficient heat resistance.

The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
