Description

Technical Field

[0001] This utility model relates to the technical field of capacitor pin detection, and in particular to a fixture for inspecting bent capacitor pins. Background Technology

[0002] For soldered aluminum electrolytic capacitors, especially multi-pin products (such as five-pin products), the incoming material of the cover plate and the manufacturing process of aluminum electrolytic capacitors can both cause the pins of the five-pin cover plate to bend.

[0003] While common testing methods can be performed in a laboratory environment, they often involve large, complex equipment that is difficult to move flexibly. If rapid testing is required on a production site or other location, the difficulty of transporting the equipment limits testing efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a fixture for inspecting the bending of capacitor leads in soldering pins in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base, a turntable rotatably mounted on the upper end of the base, multiple sets of bearing plates evenly distributed on the upper end of the turntable, a five-legged cover plate placed inside the bearing plate, and rubber can be pasted inside the bearing plate to increase the friction between the bearing plate and the five-legged cover plate. An electric telescopic rod is fixedly installed inside the base, penetrating the center of the turntable. A connecting plate is fixedly installed at the upper end of the electric telescopic rod, and a detection component is installed at the end of the connecting plate. A drive component for driving the turntable to rotate is installed inside the base.

[0006] The detection assembly includes a mounting cylinder rotatably connected to a connecting plate. A first motor for use with the mounting cylinder is mounted on the upper end of the connecting plate. The output shaft of the first motor is connected to the mounting cylinder. Two sets of clamping blocks for mutual use are installed inside the mounting cylinder. A detection fixture is set at the center position between the two clamping blocks. The mounting cylinder and the two clamping blocks are locked by pins. The electric telescopic rod is rotatably connected to the turntable.

[0007] The testing fixture consists of a testing component and a limiting component;

[0008] In practical applications, during testing, if all capacitor pins can normally enter the through holes, the pins are considered qualified; otherwise, they are unqualified. The test piece can be used for incoming inspection of the cover plate, final inspection of the capacitor process or product. After the test is completed, the electric telescopic rod rises and the second motor starts again to move the next carrier plate and five-legged cover plate to the bottom of the test piece, thus enabling a large batch of tests at once.

[0009] Since the test piece of this device is installed at the lower end of the mounting cylinder by two clamping blocks, when temporary testing is required outside the site, the staff can pull out the pin, and then take out the two clamping blocks and the test piece. This allows the staff to take the test piece out for testing alone, thereby improving the practicality of the equipment.

[0010] Furthermore, the detection component includes a detection disc, the outer wall of which has multiple sets of through holes for detecting the position of the pins in the five-legged cover plate. The through holes are evenly distributed axially. A handle is fixedly installed at the central axis of the detection disc. A groove for cooperating with the handle is opened at the middle position of the two clamping blocks. Rubber is pasted in the groove.

[0011] In practical applications, this device has six through holes, and the pins in the five-pin cover can enter any of the five corresponding through holes. If the capacitor pins can enter the through holes normally, the pins are deemed qualified; otherwise, they are unqualified. The test piece can be used for incoming inspection of the cover, capacitor process, or final inspection of the product.

[0012] Furthermore, the limiting component includes a threaded ring threaded to the outer wall of the detection disc, a fixed block welded to the inner ring of the threaded ring, and a movable block hinged to the end of the fixed block, the movable block having a concave cross-section.

[0013] In practical applications, since the cross-section of the movable block is U-shaped, the movable block can only bend upwards. However, when the movable block moves upwards, it will contact the bottom of the detection plate, so the movable block can only bend at a certain angle. This bending angle depends on the distance between the movable block and the detection plate.

[0014] When the moving block, driven by the testing component, falls and directly detects the top of the pin in the five-pin cover, the moving block bends and slides off the top of the pin until it encounters the next pin. This causes the pin in the five-pin cover to rotate synchronously and align with the through hole. By rotating synchronously with the through hole, one pin in the five-pin cover is aligned with one through hole. Other qualified pins can then enter the corresponding through hole synchronously, while unqualified pins will be bent.

[0015] Furthermore, the drive assembly includes a fixed cylinder fixed to the lower end of the turntable, the fixed cylinder being rotatably connected to the base, a worm gear being fixedly provided on the outer wall of the fixed cylinder, a worm being rotatably provided inside the base, and a second motor cooperating with the worm being installed on the outer wall of the base, the output shaft of the second motor being fixedly connected to the worm.

[0016] In practical applications, when the turntable needs to rotate, the second motor starts, and the output shaft of the second motor drives the worm to rotate. The worm drives the worm wheel to rotate, and the worm wheel drives the fixed cylinder to rotate. The fixed cylinder drives the turntable to rotate, thereby moving the turntable, the bearing plate, and the five-legged cover plate to the bottom of the test piece, making it convenient for staff to use.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] During testing, if all capacitor pins can be normally inserted into the through holes, the pins are deemed qualified; otherwise, they are deemed unqualified. The test piece can be used for incoming inspection of the cover plate, capacitor process or final inspection of the product. After the test is completed, the electric telescopic rod rises and the second motor starts again to move the next carrier plate and five-legged cover plate to the bottom of the test piece, so that a large number of tests can be carried out at once.

[0019] Since the test piece of this device is installed at the lower end of the mounting cylinder by two clamping blocks, when temporary testing is required outside the site, the staff can pull out the pin, and then take out the two clamping blocks and the test piece. This allows the staff to take the test piece out for testing alone, thereby improving the practicality of the equipment. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figure 1-6 A fixture for inspecting the bending of capacitor pin leads of soldering pins includes a base 10, a turntable 1 rotatably mounted on the upper end of the base 10, multiple sets of bearing plates 2 evenly distributed on the upper end of the turntable 1, a five-legged cover plate 3 placed inside the bearing plate 2, and rubber can be pasted inside the bearing plate 2 to increase the friction between the bearing plate 2 and the five-legged cover plate 3. An electric telescopic rod 4 is fixedly installed inside the base 10, the electric telescopic rod 4 passes through the center of the turntable 1, a connecting plate 5 is fixedly installed at the upper end of the electric telescopic rod 4, a detection component 6 is installed at the end of the connecting plate 5, and a drive component 8 for driving the turntable 1 to rotate is installed inside the base 10.

[0030] The detection component 6 includes a mounting cylinder 601 rotatably connected to the connecting plate 5. A first motor 602 is mounted on the upper end of the connecting plate 5 to cooperate with the mounting cylinder 601. The output shaft of the first motor 602 is connected to the mounting cylinder 601. Two sets of clamping blocks 603 that cooperate with each other are installed inside the mounting cylinder 601. A detection fixture is set at the center position between the two clamping blocks 603. The mounting cylinder 601 and the two clamping blocks 603 are locked together by a pin 604. The electric telescopic rod 4 is rotatably connected to the turntable 1.

[0031] The testing fixture consists of a testing component 7 and a limiting component 9;

[0032] In practical applications, when testing is required, the operator places the five-legged cover plate 3 to be tested inside the carrier plate 2. Then, the operator starts the second motor, causing the turntable 1 to rotate. The turntable 1 moves the carrier plate 2 and the five-legged cover plate 3 until they reach the bottom of the test piece 7. Then, the electric telescopic rod 4 slowly retracts, and at the same time, the first motor 602 starts. The output shaft of the first motor 602 drives the mounting cylinder 601 to rotate. The mounting cylinder 601 drives the test piece 7 to rotate through two clamping blocks 603. When the outer wall pins of the five-legged cover plate 3 contact the limiting piece 9, the test piece 7 drives the five-legged cover plate 3 and the carrier plate 2 to rotate. Therefore, the through hole 702 always corresponds to the outer wall pins of the five-legged cover plate 3. If all capacitor pins can enter the through hole 702 normally, the pins are deemed qualified; otherwise, they are unqualified. The test piece 7 can be used for incoming inspection of the cover plate, capacitor process inspection, or final inspection of the product. After the test is completed, the electric telescopic rod 4 rises, and the second motor starts again to move the next carrier plate 2 and five-legged cover plate 3 to the bottom of the test piece 7, thus enabling large-scale testing at once.

[0033] Since the testing component 7 of this device is installed at the lower end of the mounting cylinder 601 by two clamping blocks 603, when temporary testing is required outside the site, the staff can pull out the pin 604, and then take out the two clamping blocks 603 and the testing component 7. Thus, the staff can take the testing component 7 out for testing alone, thereby improving the practicality of this equipment.

[0034] Furthermore, the detection component 7 includes a detection disc 701. The outer wall of the detection disc 701 is provided with multiple sets of through holes 702 for detecting the position of the pins in the five-legged cover plate 3. The through holes 702 are evenly distributed axially. A handle 703 is fixedly provided at the central axis position of the detection disc 701. A groove for cooperating with the handle 703 is provided at the middle position of the two clamping blocks 603. Rubber is pasted in the groove.

[0035] In practical applications, this device has six through holes 702, and therefore the pins in the five-pin cover plate 3 can enter any of the five corresponding through holes 702. If the capacitor pins can enter the through holes 702 normally, the pins are deemed qualified; otherwise, they are unqualified. The test piece 7 can be used for incoming inspection of the cover plate, capacitor process, or final inspection of the product.

[0036] Furthermore, the limiting component 9 includes a threaded ring 901 threadedly connected to the outer wall of the detection disc 701. A fixing block 902 is welded to the inner ring of the threaded ring 901. A movable block 903 is hinged to the end of the fixing block 902. The movable block 903 has a concave cross-section.

[0037] In practical applications, since the cross-section of the movable block 903 is U-shaped, the movable block 903 can only bend upwards. However, when the movable block 903 moves upwards, it will contact the bottom of the detection disk 701. Therefore, the movable block 903 can only bend at a certain angle. This bending angle depends on the distance between the movable block 903 and the detection disk 701.

[0038] When the detection component 7 drives the movable block 903 to fall and directly detects the top of the pin in the five-pin cover plate 3, the movable block 903 will bend and slide off the top of the pin until it encounters the next pin. This causes the pin in the five-pin cover plate 3 to rotate synchronously and align with the through hole 702. By rotating synchronously with the through hole 702, one pin in the five-pin cover plate 3 is aligned with one through hole 702. Other qualified pins can enter the corresponding through hole synchronously, while unqualified pins will be bent.

[0039] Furthermore, the drive assembly 8 includes a fixed cylinder 801 fixed at the lower end of the turntable 1. The fixed cylinder 801 is rotatably connected to the base 10. A worm gear 802 is fixedly provided on the outer wall of the fixed cylinder 801. A worm 803 is rotatably provided inside the base 10. A second motor that works with the worm 803 is installed on the outer wall of the base 10. The output shaft of the second motor is fixedly connected to the worm 803.

[0040] In practical applications, when the turntable 1 needs to rotate, the second motor starts, and the output shaft of the second motor drives the worm gear 803 to rotate. The worm gear 803 drives the worm wheel 802 to rotate, and the worm wheel 802 drives the fixed cylinder 801 to rotate. The fixed cylinder 801 drives the turntable 1 to rotate, so that the turntable 1 drives the bearing plate 2 and the five-legged cover plate 3 to move to the lower end of the test piece 7, thus facilitating the use of the staff.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
