The cover is movably disposed at the bottom of the substrate and can completely cover the lens. The traction mechanism is disposed in the track block. When the track block moves toward the middle of the fixture cover, the traction mechanism is used to drive the cover to flip so as to completely expose the lens.

[0007] As a further improvement to the above solution, the cover is rotated at an angle of 180 degrees.

[0008] As a further improvement to the above solution, the traction mechanism includes a roller disposed in the track block, the roller part protruding from the bottom wall of the track block and rollingly engaging with the inner side wall of the guide rail, a first bevel tooth fixed on the roller axle, and a second bevel tooth meshing with the first bevel tooth installed in the track block, and a first thread wheel fixed on the tooth shaft of the second bevel tooth;

The free end of the second pull rope is bolted and fixed to the synchronization plate. Slide grooves parallel to the extension direction are opened on the opposite sides of the two convex blocks, and the two ends of the synchronization plate are elastically inserted into the two slide grooves respectively.

[0013] As a further improvement to the above solution, a sliding rod is fixed in the slide groove, and the two ends of the synchronization plate extend into the two slide grooves respectively and are slidably sleeved on the outside of the two sliding rods respectively. A first spring is sleeved on the outside of the sliding rod, and the two ends of the first spring are fixed to the side wall of the synchronization plate and the corresponding groove wall of the slide groove respectively.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example 1

[0032] Please combine Figures 1 to 2 The TP / OTP programming integrated fixture includes a fixture base box 6, a fixture cover plate 4 on the top of the fixture base box 6, and a test motherboard 8 placed between the fixture base box 6 and the fixture cover plate 4. The top of the fixture cover plate 4 is respectively provided with a product test carrier board 5 and a guide rail 1. The product to be programmed and tested is placed on the product test carrier board 5 and connected to the test motherboard 8 through an adapter FPC.

[0033] The guide rail 1 is parallel to one side of the long side of the fixture cover plate 4. A movable track block 33 is provided in the guide rail 1. A frame 2 is mounted on the track block 33. A base plate 9 is provided on the frame 2. A camera 3 with a lens 10 facing the product test carrier plate 5 is mounted on the base plate 9. In this embodiment, a slot 22 is provided on the base plate 9, which can be inserted into the slot 22 to complete the positioning and fixation of the camera 3 and its lens 10 on the base plate 9.

[0034] The working principle of this embodiment is as follows:

[0035] During the programming process, the track block 33 is moved from one end of the guide rail 1 away from the middle of the fixture cover plate 4 (upper limit) to the opposite end of the guide rail 1 (lower limit), so that the lens 10 of the camera 3 is positioned at the center of the product to be programmed, which is pre-placed on the product test carrier board 5. The test switch 7 on the side wall of the fixture base box 6 is pressed to start programming the TPFW. After the FW programming is completed, the test motherboard 8 automatically enters the OTP programming mode. After both TPFW and OTP programming are completed, the test switch 7 is pressed again, the test motherboard 8 is powered off, the lens 10 of the camera 3 is pushed to the upper limit of the guide rail 1, the test FPC is disconnected, and the product is removed. This embodiment optimizes the testing process and improves testing efficiency; it also reduces the cost of the functional testing fixture and labor costs, demonstrating significant practical effects.

[0036] Example 2

[0037] Please combine Figures 3 to 9 This embodiment is an improvement on embodiment 1. The TP / OTP programming integrated fixture also includes a protective device. The protective device includes a cover 12 and a traction mechanism. The cover 12 is rotatably disposed at the bottom of the substrate 9 and can completely cover the lens 10, playing a certain protective role and preventing the lens 10 from being contaminated or damaged by the external environment when it is not in use (the track block 33 is at the upper limit position in the guide rail 1).

[0038] The traction mechanism is located in the track block 33. When the track block 33 moves toward the middle of the fixture cover plate 4, the traction mechanism is used to rotate the cover 12 by 180 degrees to fully expose the lens 10 so that the lens 10 can be aligned and focused on the center of the product to be burned during the burning operation.

[0039] The traction mechanism includes a roller 13 disposed within the track block 33. Part of the roller 13 protrudes from the bottom wall of the track block 33 and rolls in cooperation with the inner wall of the guide rail 1. That is, when the track block 33 moves within the guide rail 1, it drives the roller 13 to rotate. A first bevel tooth 14 is fixed on the axle of the roller 13. A second bevel tooth 15 that meshes with the first bevel tooth 14 is also installed in the track block 33. A first spool 16 is fixed on the axle of the second bevel tooth 15.

[0040] A spool 11 is fixedly inserted on one side of the cover 12. The spool 11 is elastically inserted into the bottom of the base plate 9. A second spool 17 is sleeved and fixed on the outside of the spool 11. A first pull rope is wound on the second spool 17. The free end of the first pull rope is wound around the first spool 16.

[0041] Two protruding blocks 18 are arranged opposite each other on the bottom of the substrate 9, located on both sides of the slot 22. The protruding blocks 18 are perpendicular to the guide rail 1. The two protruding blocks 18 have shaft holes (not shown) on opposite sides. The two ends of the scroll 11 are respectively inserted into the two shaft holes, and the scroll 11 is connected to the shaft holes by a coil spring. When the cover 12 completely seals the lens 10, the coil spring is in a non-deformed state.

[0042] In this embodiment, the traction mechanism operates as follows:

[0043] As the track block 33 moves from the upper limit to the lower limit in the guide rail 1, it causes the roller 13 to rotate. The roller 13 drives the first bevel tooth 14, the second bevel tooth 15, and the first spool 16, causing the first spool 16 to wind up the first pull rope. The first pull rope then drives the second spool 17, the spool 11, and the cover 12 to rotate synchronously (during which the coil spring is compressed and deformed). When the track block 33 moves to the lower limit, the cover 12 rotates 180 degrees to fully expose the lens 10. At this time, the lens 10 is precisely focused on the center of the product to be burned, facilitating subsequent burning operations.

[0044] After the burning process is complete, the track block 33 is moved from the lower limit to the upper limit in the guide rail 1. The roller 13 drives the first bevel tooth 14, the second bevel tooth 15, and the first spool 16 to rotate in the opposite direction. The first spool 16 releases the previously wound first pull rope. The spring force releases, causing the spool 11, the second spool 17, and the cover 12 to rotate synchronously. This causes the second spool 17 to wind up the previously released first pull rope, and causes the cover 12 to flip back to its initial position. When the track block 33 moves to the upper limit, the cover 12 completes a 180-degree rotation to completely cover the lens 10, preventing the lens 10 from being contaminated or damaged by external environmental factors when not in use.

[0045] The protective device also includes a cleaning mechanism, which includes a timing plate 21 parallel to the roller 11. The two ends of the timing plate 21 are respectively inserted into the opposite side walls of the two protruding blocks 18, and can move relative to each other in the extending direction of the protruding blocks 18.

[0046] A scraper 23 is elastically mounted on the side of the synchronization plate 21 facing the lens 10. The scraper 23 is made of flexible cotton material to avoid scratching the lens 10. In this embodiment, the scraper 23 moves synchronously with the synchronization plate 21 so that the scraper 23 can move relative to the lens 10 to clean the surface of the lens on the lens 10.

[0047] A third reel 24 is sleeved and fixed on the reel 11. A second pull rope is wound around the third reel 24, and the free end of the second pull rope is bolted and fixed to the synchronization plate 21. The synchronization plate 21 is moved toward the reel 11 by the second pull rope on the third reel 24. Each of the two protruding blocks 18 has a groove 19 parallel to its extension direction on opposite sides. The two ends of the synchronization plate 21 are elastically inserted into the two grooves 19 respectively. The grooves 19 make the movement of the synchronization plate 21 more stable.

[0048] A slide rod 20 is fixed in the slide groove 19. The two ends of the synchronization plate 21 extend into the two slide grooves 19 respectively and are slidably sleeved on the outside of the two slide rods 20. The slide rods 20 make the movement of the synchronization plate 21 in the slide groove 19 smoother and more stable. A first spring (not shown) is sleeved on the outside of the slide rod 20. The two ends of the first spring are fixed to the side wall of the synchronization plate 21 and the corresponding groove wall of the slide groove 19 respectively. When the synchronization plate 21 is located on the side closer to the roller 11, the cover 12 is fully opened and the first spring is in a stretched deformation state.

[0049] In this embodiment, the cleaning mechanism operates as follows:

[0050] When the scroll 11 drives the cover 12 to flip open, the scroll 11 will drive the third pulley 24 to rotate, causing the third pulley 24 to wind up the second pull rope, thereby driving the synchronization plate 21 to move towards the scroll 11 (the first spring is stretched and deformed), so as to drive the scraper 23 to move relative to the lens 10, complete the cleaning of the lens surface on the lens 10, and ensure the positioning accuracy of the camera 3.

[0051] Similarly, when the spool 11 drives the cover 12 to flip and close, the spool 11 will drive the third pulley 24 to rotate in the opposite direction, causing the third pulley 24 to release the second pull rope that was originally wound up, and under the release action of the first spring, it will pull the synchronization plate 21 to move away from the spool 11 until the initial position. During this period, the synchronization plate 21 drives the scraper 23 to move in the opposite direction relative to the lens 10, and cleans the lens surface on the lens 10 again, ensuring the cleanliness of the lens 10 of the camera 3 after use.

[0052] The synchronization plate 21 elastically supports the first cylinder 26 with negative pressure inside on the side facing the lens 10. The scraper 23 is fixed on the side of the first cylinder 26 facing the lens 10. The first cylinder 26 has at least one dust inlet 27 communicating with its interior on the front and rear sides in the direction of movement.

[0053] In this embodiment, since there is negative pressure inside the first cylinder 26, the dust generated during the cleaning of the lens 10 by the scraper 23 can be sucked into the first cylinder 26 in time through the dust inlet 27, so as to avoid it remaining in the cover 12.

[0054] Furthermore, the elastic support method of the first cylinder 26 on the synchronization plate 21 is as follows: a telescopic rod (not shown) is provided between the synchronization plate 21 and the first cylinder 26, and a second spring (not shown) is sleeved on the outside of the telescopic rod. The two ends of the second spring are respectively fixed to the corresponding plate wall of the synchronization plate 21 and the corresponding outer wall of the first cylinder 26. The second spring can buffer the contact force between the scraper 23 and the lens 10, reducing damage to the lens 10.

[0055] The scraper 23 has guide slopes 231 on both the front and rear sides in its direction of movement. Each guide slope 231 can guide the dust and dirt scraped by the scraper 23 on the lens 10 in the direction of movement to the dust inlet 27 in time, so as to be sucked into the first cylinder 26 in time.

[0056] In this embodiment, the negative pressure inside the first cylinder 26 is achieved as follows:

[0057] The first cylinder 26 is hollow inside, closed at one end, and open at the other end. A second cylinder 28, which is adapted to fit the first cylinder 26, is detachably installed at the open end of the first cylinder 26. When the second cylinder 28 is installed on the first cylinder 26, one end of the second cylinder 28 is connected to the first cylinder 26. The interior of the second cylinder 28 is a dust collection chamber, in which a filter layer 29 is installed. A miniature air pump 30 is installed at the other end of the second cylinder 28, connecting to its interior. The suction action of the miniature air pump 30 creates a negative pressure in the first cylinder 26, causing the dust drawn into the first cylinder 26 to move axially within it and be intercepted and adsorbed in the filter layer 29 of the second cylinder 28. When maintenance and cleaning are required, the second cylinder 28 can be easily and quickly removed from the first cylinder 26 to clean the dust in the filter layer 29.

[0058] To enable the micro air pump 30 to automatically start when the scraper 23 cleans the lens 10 and automatically shut down when the scraper 23 does not clean the lens 10, this embodiment provides two opposing limiting grooves 32 at the bottom of the substrate 9. The two limiting grooves 32 are located between and parallel to the two protruding blocks 18, and are located on both sides of the slot 22. The closed end of the first cylinder 26 is slidably engaged in one of the limiting grooves 32, and the second cylinder 28 on the open end side of the first cylinder 26 is slidably engaged in the other limiting groove 32. A touch switch 31 is installed on the top of the second cylinder 28, and a battery (not shown) that can power the micro air pump 30 is also installed in the inner wall. The upper groove walls at both ends of the limiting groove 32 are inclined upward and outward to form flared sections (not shown) to increase the vertical spacing of the limiting grooves 32.

[0059] When the second cylinder 28 is in the flared section, there is a gap between the pressure switch 31 and the wall of the limiting groove 32 in the flared section, that is, the pressure switch 31 does not contact the wall of the limiting groove 32 in the flared section, so the micro air pump 30 does not work, and the cover 12 is in a fully open or fully covered state.

[0060] When the second cylinder 28 moves from any flared section to the middle of the limiting groove 32, the vertical spacing of the limiting groove 32 gradually decreases. When it leaves the flared section, the touch switch on the second cylinder 28 will be subjected to downward pressure from the upper groove wall of the limiting groove 32, and the micro air pump 30 will work. At this time, the scraper 23 just contacts the surface of the lens 10 so as to suck away the scraped dust and dirt in time.

[0061] In summary, this embodiment enables the track block 33 to move from the upper limit to the lower limit in the guide rail 1, while the flip cover 12 fully exposes the lens 10, the scraper 23 moves the lens 10 for cleaning, and the micro air pump 30 automatically starts and stops to remove dust and dirt, so as to carry out subsequent burning operations.

[0062] In addition, during the process of the track block 33 returning from the lower limit to the upper limit in the guide rail 1, the scraper 23 moves to clean the lens 10, the micro air pump 30 automatically turns on and off to suck up dust and dirt, and the flip cover 12 completely covers the lens 10 to prevent the lens 10 from being contaminated or damaged by the external environment when it is not in use.

[0063] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
