The main types of photoelectric devices are: phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, photocells and photocouplers.

[0003] When manufacturing and processing the optoelectronic device, a positioning fixture is needed to clamp and position the optoelectronic device to prevent the optoelectronic device from displacement.

[0004] The authorization announcement number in the prior art is: CN211743177U, and the name is a positioning fixture for manufacturing optoelectronic devices. By setting an L-shaped rod, when the optoelectronic device body is placed on the surface of the anti-static film, the electric push rod is started to drive the electric push rod to move downward, and the slider moves downward accordingly. The two pulleys slide on the inner wall of the limit groove, and the bottoms of the two L-shaped rods are close to each other to clamp the optoelectronic device body. Then, the motor is started to drive the rotating rod to rotate, so that the left side of the positioning rod is pressed down, and the positioning block contacts the optoelectronic device body. By using the cooperation of the above structure, the two L-shaped rods can move synchronously during positioning, and the positioning fixture is flexible to use.

[0005] However, in actual use, it was found that when the above device was used to position and clamp optoelectronic devices of different sizes, the two L-shaped rods could not be clamped in parallel, and the optoelectronic devices of different sizes could not be clamped stably.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] See also Figure 1-5 A positioning fixture for manufacturing optoelectronic devices includes a processing plate 1, a clamping mechanism 4 and a positioning mechanism 5.

[0030] An antistatic film 2 is fixedly connected to the upper surface of the processing plate 1, and a photoelectric device body 3 is placed on the upper surface of the antistatic film 2. The antistatic film 2 is an existing structure, and the antistatic film 2 can prevent static electricity from causing damage to the photoelectric device body 3.

[0031] The bottom surface of the processing plate 1 is fixedly connected with an anti-skid pad 6. The anti-skid pad 6 can increase the friction force of the bottom surface of the processing plate 1, so that the device can be placed on the contact surface more stably.

[0032] Fixing bolts 7 are installed at the four corners of the processing plate 1. The bottom ends of the four fixing bolts 7 penetrate the anti-slip pad 6 and extend to the outside of the anti-slip pad 6. By setting the fixing bolts 7, the device can be easily positioned in a suitable position, which facilitates the positioning and clamping of the optoelectronic device body 3 more stably.

[0033] The clamping mechanism 4 includes a hydraulic cylinder 401 fixedly connected to the upper surface of the processing plate 1 and a wedge frame 402 fixedly connected to the output end of the hydraulic cylinder 401. When the hydraulic cylinder 401 is started, the wedge frame 402 is driven to move.

[0034] And a fixing plate 403 fixedly connected to the upper surface of the processing plate 1, the outer surface of the fixing plate 403 is fixedly connected to two elastic telescopic components 404, and the output end of each elastic telescopic component 404 is fixedly connected to a wedge block 405.

[0035] The shapes of the two wedge blocks 405 are respectively adapted to the shapes of the two sides of the wedge frame 402. By limiting the relationship between the wedge blocks 405 and the wedge frame 402, the two wedge blocks 405 can move closer to or away from each other through the movement of the wedge frame 402.

[0036] The elastic telescopic component 404 is composed of a telescopic rod and a telescopic spring. When the wedge frame 402 moves toward the fixed plate 403, the two wedge blocks 405 will move closer to each other, so that the two elastic telescopic components 404 are in a contracted state. At the same time, the telescopic springs in the two elastic telescopic components 404 will deform and generate elastic force. The generated elastic force can facilitate the subsequent resetting of the two wedge blocks 405.

[0037] The outer surfaces of the two wedge blocks 405 are fixedly connected with L-shaped clamping rods 406. Since the L-shaped clamping rods 406 and the wedge blocks 405 are fixedly connected, when the wedge blocks 405 move, the corresponding L-shaped clamping rods 406 will move accordingly.

[0038] In this way, the two L-shaped clamping rods 406 can move towards or away from each other, so that the two L-shaped clamping rods 406 can centrally clamp the optoelectronic device bodies 3 of different sizes, and during the clamping process, the two L-shaped clamping rods 406 always remain parallel, which can ensure stable clamping of optoelectronic device bodies 3 of different sizes.

[0039] The outer surfaces of the two L-shaped clamping rods 406 are respectively slidably mounted in the sliding grooves opened on both sides of the fixing plate 403 , and the two L-shaped clamping rods 406 are respectively located on both sides of the antistatic film 2 .

[0040] By limiting the positional relationship of the L-shaped clamping rods 406 , the two L-shaped clamping rods 406 can more stably clamp the optoelectronic device body 3 placed on the upper surface of the antistatic film 2 .

[0041] The guide posts 407 are fixedly connected to the slide grooves on both sides of the fixed plate 403 , and the inner walls of the two L-shaped clamping rods 406 are slidably sleeved on the outer surfaces of the two guide posts 407 .

[0042] The guide column 407 can make the L-shaped clamping rod 406 more stable when moving, thereby improving the smoothness of the device when clamping the optoelectronic device body 3.

[0043] The positioning mechanism 5 includes a bracket 501 fixedly connected to the upper surface of the fixed plate 403 and a positioning rod 502 rotatably mounted on the inner wall of the bracket 501 . The rotating shaft end of the positioning rod 502 is fixedly connected to a worm gear 503 . A worm 504 meshing with the worm gear 503 is installed on the upper surface of the fixed plate 403 .

[0044] The rotating shaft end of the worm 504 is fixedly connected with a handle 505 , and the outer surface of the handle 505 is coated with an anti-skid layer. By providing the handle 505 , the contact area of ​​the rotating shaft end of the worm 504 can be increased, making it easier to rotate the worm 504 .

[0045] The combination of the worm 504 and the worm wheel 503 has the effects of deceleration and self-locking. The deceleration effect can facilitate the staff to control and adjust the position of the positioning rod 502.

[0046] The self-locking effect can limit the rotation of the positioning rod 502. The positioning rod 502 will not rotate freely. The worm gear 503 can only be driven by the worm 504 to rotate, thereby realizing the rotation of the positioning rod 502. Therefore, the positioning rod 502 can press down the optoelectronic device body 3 clamped between the two L-shaped clamping rods 406 to achieve the effect of positioning the optoelectronic device body 3.

[0047] The specific implementation process of the utility model is as follows: when clamping and positioning the photoelectric device body 3, the photoelectric device body 3 is first placed on the antistatic film 2, and then the hydraulic cylinder 401 is started to work, so that the hydraulic cylinder 401 drives the wedge frame 402 to move toward the fixed plate 403. During the movement of the wedge frame 402, the two wedge blocks 405 will move closer to each other, and the two elastic telescopic components 404 will be in a compressed state. When the two wedge blocks 405 move, the two L-shaped clamping rods 406 will also move, so the two L-shaped clamping rods 406 can move closer to each other along the two guide columns 407 respectively, so that the photoelectric device body 3 placed on the antistatic film 2 can be centered and clamped, and the two L-shaped clamping rods 406 remain parallel during the clamping process, which can The work of clamping the optoelectronic device body 3 of different sizes can be performed more stably. Then the handle 505 can be rotated to adjust the positioning rod 502 to position the optoelectronic device body 3. When the handle 505 is rotated, the worm 504 will be driven to rotate. When the worm 504 is rotated, the positioning rod 502 can be driven to rotate by the worm gear 503. The staff needs to rotate one end of the positioning rod 502 toward the optoelectronic device body 3, and then press the optoelectronic device body 3 down on the antistatic film 2 through the positioning rod 502 to achieve the positioning of the optoelectronic device body 3. Since the position of the positioning rod 502 can be flexibly adjusted, the positioning work of the optoelectronic device body 3 of different thicknesses can be achieved. In this way, the clamping mechanism 4 and the positioning mechanism 5 cooperate with each other to meet the clamping and positioning work of various optoelectronic device bodies 3, which is more practical.

[0048] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
