Description

Technical Field

[0001] This utility model relates to the field of electronic component processing technology, specifically to an auxiliary positioning device for electronic component testing. Background Technology

[0002] Camera inspection of electronic components is a key quality control step in modern intelligent manufacturing. Utilizing high-precision industrial cameras and machine vision technology, components are automatically inspected for appearance, size, and markings. This technology can quickly identify defects such as deformed pins, poor solder joints, surface scratches, and blurred characters, with inspection accuracy reaching the micrometer level. This provides a reliable technical guarantee for product quality control and production process optimization.

[0003] In existing technologies, most fixtures only use a single clamp to fix components. After the current component is tested, manual disassembly is required before the next component to be tested can be clamped. This frequent start-stop process makes the testing efficiency extremely low, and its unfriendly nature is particularly prominent when facing batch testing scenarios. Moreover, since the testing camera is often fixed, the operator must manually loosen the bolts, rotate it to the appropriate angle, and then tighten it again before testing. The entire adjustment process is extremely time-consuming and labor-intensive. Even more troublesome is that the fixture size is fixed and cannot be adapted to different specifications of components. For example, when testing chips and capacitors, different fixtures must be changed, which greatly increases the complexity and cost of operation. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides an embodiment: an auxiliary positioning device for electronic component testing, including a base 1 with an internal cavity, a rotating assembly inside the cavity, a drive source 2 installed on the side wall of the base 1, the drive source 2 driving the rotating assembly, a bearing turntable 3 fixedly connected to the output end of the driving rotating assembly, a partition plate 4 fixedly connected to the upper end surface of the bearing turntable 3, the partition plate 4 dividing the bearing turntable 3 into at least four positioning areas, each positioning area having a fixing assembly, the fixing assembly including a groove 5 formed on the upper end surface of the bearing turntable 3, a sliding structure set in the groove 5, a base 6 set on the moving end of the sliding structure, a second base 7 fixedly connected to the upper surface of the bearing turntable 3, a movable clamp 8 detachably connected to the first base 6 and a fixed clamp 9 detachably connected to the second base 7, the clamping surfaces of the movable clamp 8 and the fixed clamp 9 both having V-grooves 10, a support plate 11 also fixedly connected to the upper end surface of the bearing turntable 3, the support plate 11 containing... A sliding rod 12 is slidably connected, with one end of the sliding rod 12 fixedly connected to the surface of the movable clamp 8. A spring 13 is sleeved on the outer wall of the sliding rod 12, and the two ends of the spring 13 are respectively connected to the support plate 11 and the movable clamp 8. The base 1 is made of aluminum alloy and formed by precision casting. The turntable is a steel structure with partition plates 4 installed on its surface. A positioning hole is set in the center of the turntable. The partition plates 4 are made of polycarbonate plates, and each partition plate 4 has an included angle of 90°, dividing the turntable into 4 sector areas. The sector partitions support multi-station detection and improve detection efficiency. The first base 6 is an aluminum alloy block, and the movable clamp 8 is a stainless steel part. The second base 7 has the same structure as the first base 6. The fixed clamp 9 is made of the same material as the movable clamp 8. The V-groove 10 has an included angle of 60°-90° and is plated with hard chrome. The support plate 11 is a carbon steel welded part, and the sliding rod 12 is a stainless steel optical shaft. The spring 13 provides preload force to make the movable clamp 8 automatically reset. The drive source 2 can be a servo motor, thus providing selectable rotation power.

[0024] Please see Figure 1A further embodiment of this solution is as follows: A bracket 14 and a bearing seat 15 are fixedly connected to the upper end face of the base 1. A second drive source 16 is installed on the top of the bracket 14. A lead screw 17 is rotatably connected inside the bearing seat 15. One end of the lead screw 17 is fixedly connected to the output shaft of the second drive source 16. A lifting plate 18 is threadedly connected to the threaded section of the lead screw 17. A support cantilever 19 is fixedly connected to the side end of the lifting plate 18. An adjustment component is provided on the support cantilever 19. A transmission rod is fixedly connected to the output end of the adjustment component. 21. A mounting plate 22 is fixedly connected to the end of the transmission rod 21. A detection camera 23 is installed on the mounting plate 22. A guide rod 24 is fixedly connected between the bracket 14 and the base 1. The outer wall of the guide rod 24 is slidably connected to the lifting plate 18. The bracket 14 is used to support the second drive source 16. The first bearing seat 15 provides rotational support for the lead screw 17, allowing the lead screw 17 to rotate smoothly inside it. The second drive source 16 serves as a power source, providing driving force for the rotation of the lead screw 17. The power is transmitted through the output shaft. The transmission is transmitted to the lead screw 17, which rotates under the drive of the second drive source 16. Its threaded section is threadedly connected to the lifting plate 18. When the lead screw 17 rotates, the rotational motion is converted into the linear motion of the lifting plate 18 by the transmission action of the thread. The lifting plate 18 provides vertical displacement for the support cantilever 19 and the components mounted on the support cantilever 19. The support cantilever 19 is used to install the adjustment component, which is used to adjust the position of the transmission rod 21, thereby changing the shooting angle or position of the detection camera 23 on the mounting plate 22. The mounting plate 22 serves as the mounting carrier for the detection camera 23, providing a stable mounting position for the detection camera 23. The detection camera 23 is used to perform operations such as detection of electronic components and to acquire relevant image information. The guide rod 24 is slidably connected to the lifting plate 18, which plays a guiding role, ensuring that the lifting plate 18 moves along a straight line during the up and down movement and preventing it from deviating. The second drive source 16 can be a rotary motor, thereby providing selective rotational power.

[0025] Please see Figure 3 A further solution based on this embodiment is as follows: The adjustment component includes a drive source 25 mounted on the upper surface of the support cantilever 19. The output shaft of the drive source 25 passes through the support cantilever 19 and is fixedly connected to a spur gear 26. An internal gear ring 27 is rotatably connected to the lower surface of the support cantilever 19. The spur gear 26 meshes with the internal gear ring 27. The outer wall of the internal gear ring 27 is fixedly connected to one end of the transmission rod 21. The drive source 25 provides power to the adjustment component and transmits the power to the spur gear 26 through the output shaft. The spur gear 26 rotates under the drive of the drive source 25 and transmits the power to the internal gear ring 27. When the spur gear 26 rotates, it drives the internal gear ring 27 to rotate around its own axis. The rotation of the internal gear ring 27 drives the transmission rod 21 to make a circular motion, thereby realizing the adjustment of the angle of the detection camera 23. The drive source 25 can be a rotary motor to provide selective rotation power.

[0026] Please see Figure 2A further embodiment of this solution is as follows: the rotating assembly includes a bearing seat 28 fixedly attached to the bottom of the cavity, a support shaft 29 rotatably connected inside the bearing seat 28, the upper end of the support shaft 29 being fixedly connected to the lower end of the bearing turntable 3, a bearing seat 30 fixedly attached to one inner wall of the cavity, a worm gear 31 rotatably connected inside the bearing seat 30, one end of the worm gear 31 being connected to the output shaft of the drive source 2, a worm wheel 32 fixedly attached to the outer wall of the support shaft 29, and the worm gear 31 meshing with the worm wheel 32. The bearing seat 28 serves as the support shaft 2. 9 provides rotational support, enabling the support shaft 29 to rotate smoothly within it. The support shaft 29 drives the bearing turntable 3 to rotate under the drive of the rotating assembly, thereby realizing the switching of the work position on the bearing turntable 3. The bearing housing 30 provides rotational support for the worm 31, enabling the worm 31 to rotate smoothly within it. The worm 31 rotates under the drive of the drive source 2 and transmits power to the worm wheel 32. When the worm 31 rotates, it drives the worm wheel 32 to rotate. The rotation of the worm wheel 32 drives the support shaft 29 and the bearing turntable 3 to rotate.

[0027] Please see Figure 4 A further solution based on this embodiment is as follows: the sliding structure includes a slide rail 33 disposed at the bottom of the groove 5, a slider 34 slidably connected on the slide rail 33, the connecting surface of the slider 34 being fixedly connected to the lower end surface of the movable clamp 8, the slide rail 33 providing a sliding track for the slider 34, so that the slider 34 can slide along a straight line on it, and when the slider 34 slides on the slide rail 33, it drives the movable clamp 8 to make a straight line movement.

[0028] Please see Figure 5 A further solution based on this embodiment is as follows: both base 6 and base 7 have insertion holes 35. The lower ends of the movable clamp 8 and the fixed clamp 9 are fixedly connected to insertion rods 36 that are adapted to the insertion holes 35. The insertion rods 36 are inserted into the insertion holes 35. The contact surfaces of the insertion rods 36 and the insertion holes 35 are provided with permanent magnets. The insertion rods 36 and the insertion holes 35 are magnetically connected. The insertion holes 35 provide installation positions for the movable clamp 8 and the fixed clamp 9. The movable clamp 8 and the fixed clamp 9 are fixed by the connection between the insertion rods 36 and the insertion holes 35. The magnetic connection enhances the connection stability between the insertion rods 36 and the insertion holes 35 and prevents the movable clamp 8 and the fixed clamp 9 from loosening during operation.

[0029] Please see Figure 5 A further solution based on this embodiment is as follows: a limiting groove 38 is formed on the inner wall of the insertion hole 35, and a convex rail 37 adapted to the limiting groove 38 is integrally fixed to the outer wall of the insertion rod 36. The convex rail 37 is slidably connected to the limiting groove 38, and the limiting groove 38 provides a sliding track for the convex rail 37. When the insertion rod 36 is inserted into the insertion hole 35, the convex rail 37 slides along the limiting groove 38 to prevent the insertion rod 36 from rotating in the insertion hole 35.

[0030] Working principle: According to the specifications of electronic components, select the appropriate moving clamp 8 and fixed clamp 9, and insert the insertion rod 36 at the lower end of the moving clamp 8 and fixed clamp 9 into the insertion hole 35 on the base 1 6 and the base 2 7 respectively. Since the contact surface between the insertion rod 36 and the insertion hole 35 is provided with a permanent magnet, the two are firmly connected by magnetism. At the same time, the convex rail 37 on the outer wall of the insertion rod 36 slides along the limiting groove 38 on the inner wall of the insertion hole 35 to prevent the insertion rod 36 from rotating and ensure the stability of the clamp installation.

[0031] After the clamp is installed, push the movable clamp 8 away from the fixed clamp 9. The lower end of the movable clamp 8 moves linearly through a sliding structure. Specifically, the slider 34 connected to the lower end of the movable clamp 8 slides on the slide rail 33 at the bottom of the groove 5, which drives the movable clamp 8 to move. As the movable clamp 8 moves, the distance between it and the fixed clamp 9 gradually increases until the electronic component is clamped in the V-shaped groove of the clamping surface. The surface of the V-shaped groove is plated with hard chrome, which can better fit the shape of the component and achieve stable clamping. At this time, the spring 13 sleeved on the outer wall of the slide rod 12 is compressed to provide preload force for the movable clamp 8.

[0032] After the components in a positioning area are fixed, drive source 2 is started. The output shaft of drive source 2 drives the worm 31 to rotate in bearing housing 30. The worm 31 meshes with the worm wheel 32 on the outer wall of the support shaft 29, thereby driving the worm wheel 32 to rotate. The rotation of the worm wheel 32 causes the support shaft 29 to rotate in bearing housing 28. The bearing turntable 3 connected to the upper end of the support shaft 29 rotates accordingly. The partition plate 4 divides the bearing turntable 3 into at least four positioning areas. The rotation of the bearing turntable 3 realizes the switching of different work positions, and rotates the component to be tested to the corresponding detection work position below the detection camera 23.

[0033] Next, the second drive source 16 installed on the top of the bracket 14 is started. The output shaft of the second drive source 16 drives the lead screw 17 to rotate in the bearing seat 15. The threaded section of the lead screw 17 is threadedly connected to the lifting plate 18. Under the guidance of the guide rod 24, the rotation of the lead screw 17 causes the lifting plate 18 to move vertically along the guide rod 24. The lifting plate 18 drives the support cantilever 19 and the components installed on the support cantilever 19 to move up and down together, thereby adjusting the position of the detection camera 23 in the vertical direction.

[0034] Simultaneously, the drive source 25 mounted on the upper surface of the support cantilever 19 is activated. The output shaft of the drive source 25 drives the spur gear 26 to rotate. The spur gear 26 meshes with the internal gear ring 27 rotatably connected to the lower surface of the support cantilever 19. The rotation of the spur gear 26 drives the internal gear ring 27 to rotate around its own axis. The transmission rod 21 connected to the outer wall of the internal gear ring 27 then performs a circular motion. The angle of the mounting plate 22 at the end of the transmission rod 21 and the detection camera 23 on the mounting plate 22 changes, thereby adjusting the shooting angle of the detection camera 23.

[0035] After adjusting the inspection camera 23 to a suitable position and angle, start the inspection camera 23 to inspect the electronic components at the corresponding workstation on the carrier turntable 3 and obtain relevant image information so as to analyze and judge the quality and performance of the components in the future.

[0036] After one component is tested, the push on the moving clamp 8 is released. Under the preload of the spring 13, the moving clamp 8 automatically resets along the support plate 11 via the slide bar 12. Then, the above process is repeated to fix new components in different positioning areas, and the batch testing of electronic components is completed in sequence.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
