Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example

[0031] Please refer to Figure 1-Figure 6 shown.

[0032] The present invention provides a capacitor core welding strength detection device, such as Figure 1 , Figure 2As shown in the figure, it includes a frame 1 in a "C" shape. The frame 1 is formed by welding rectangular pipes and plates. It has an installation space in a "C" shape inside. An operating table 12 is provided inside the top of the frame 1. The operating table 12 is fixed inside the frame 1 by bolts or welding, and a part of it extends out of the frame 1 and is placed outside the frame 1. A clamping mechanism for clamping the capacitor 15 is provided on the operating table 12. In this way, the capacitor 15 to be detected can be clamped on the operating table 12, which is convenient for the operator to operate and also avoids the lateral displacement or shaking of the capacitor 15 during the test, affecting the measurement result of the lead welding strength of the capacitor 15. On one side of the frame 1 away from the operating table 12, a detection mechanism 4 for measuring and detecting the pulling force is installed, which is convenient for the operator to more intuitively view the pulling force on the lead of the capacitor 15. If the force reaches the measurement upper limit, the detection operation can be stopped, and then the detection of the above-mentioned capacitor 15 is completed; two sets of clamping mechanisms for clamping the two leads of the capacitor 15 are provided inside the frame 1, which can clamp the two leads of the capacitor 15 separately, and the welding strengths of the two leads can be measured simultaneously, improving the detection efficiency; in this way, the problem of inaccurate measurement results of the lead welding strength caused by misoperation when clamping the two leads simultaneously is avoided; a driving mechanism for driving the clamping mechanism to move towards the detection mechanism 4 is provided inside the frame 1, which can control the clamping mechanism to move quickly or slowly to achieve different detection functions. The measuring end of the detection mechanism 4 is installed inside the clamping mechanism, which is beneficial to ensure the accuracy of the measurement result of the lead welding strength. Through the above structure, the detection efficiency of the leads of the capacitor 15 can be improved.

[0033] Preferably, the detection mechanism 4 is a pointer type push-pull force gauge, and its model is: [NK / NLB / ALB] series. It is a handheld product with a small volume and simple operation, and can be installed on various test benches and used in combination with various jigs for testing various products.

[0034] During actual use, the detection end of the detection mechanism 4 abuts against the mounting seat 6.

[0035] In some technical solutions of the present invention, the clamping mechanism includes two side plates 33. The two side plates 33 are respectively installed on both sides of the frame 1. The side plates 33 and the top of the frame 1 are connected by welding or bolt connection. Between the two side plates 33, there are two clamping plates 16. The bottoms of the two clamping plates 16 abut against the operating table 12. There is a clamping area between the two clamping plates 16. On the side walls of the two clamping plates 16 facing away from each other, there are two guide rods 11. Guide holes adapted to the guide rods 11 are opened on the side plates 33. A limiting spring 17 connected to the side plates 33 is sleeved on the guide rods 11. In this way, through the above structure, the width of the clamping area between the two clamping plates 16 can be controlled, so as to adapt to capacitors 15 of different sizes and increase the application range of this structure.

[0036] In some technical solutions of the present invention, limiting grooves are provided on the opposite side walls of the two clamps 16. When the capacitor 15 enters the clamping area formed between the two clamps 16, the end of the capacitor 15 is embedded in the limiting groove. In this way, displacement or shaking of the capacitor 15 in the clamping area can be avoided.

[0037] In addition, inclined surfaces are provided on the opposite side walls of the two clamps 16. The angle between the two inclined surfaces when their reverse extension lines intersect is an acute angle. They are placed in the clamping area to facilitate the capacitor 15 to better enter the clamping area formed between the two clamps 16 and reduce the obstruction of the clamps 16 to it.

[0038] In some technical schemes of the present invention, a limit block 34 is provided between the two side plates 33. The limit block 34 is triangular in shape at one end facing the capacitor 15, which is not shown in the figure. The above structure can separate the two close-fitting leads to avoid the problem that the leads are adhered to each other and the clamping mechanism cannot clamp a single lead. A cover plate 9 connected to the side plate 33 is provided on the limit block 34. The cover plate 9 is fixedly connected to the side plate 33 by bolts, and the set cover plate 9 can also prevent the capacitor 15 from flipping upward and flying out of the clamping area during the test.

[0039] In some technical schemes of the present invention, the clamping mechanism includes a mounting seat 6 and a mounting ring 8 slidably arranged in the frame 1, at least three clamping arms 10 are arranged around the mounting ring 8, and at least three clamping arms 10 are formed into a circular structure after being surrounded, one end of the clamping arm 10 has a bending portion, and the inner side of the bending portion has concave and convex scratches, which can improve the friction strength when the clamping arm 10 contacts the lead wire, and a plurality of mounting holes are arranged around the outer wall of the mounting ring 8, and guide rods 24 are penetrated in the mounting holes, and the guide rods 24 are respectively fixedly connected to the corresponding clamping arms 10 by welding, and a reset spring connected to the inner wall of the mounting hole is sleeved on the guide rod 24. The reset spring is not shown in the figure. A guide block 22 is installed on the mounting seat 6. A limiting cylinder 7 is provided on the guide block 22. Parts of the clamping arm 10 are placed in the limiting cylinder 7. A plurality of limiting protrusions are arranged around the inner wall of the limiting cylinder 7. The plurality of limiting protrusions are enclosed in the limiting cylinder 7 to form an inner cone. The cross-section of the inner cone is a right-angle trapezoid, and the limiting protrusion is integrally formed with the limiting cylinder 7. The large diameter end of the limiting protrusion is close to the mounting ring 8. The end of the clamping arm 10 placed in the limiting cylinder 7 is provided with a limiting groove adapted to the limiting protrusion. The limiting protrusion is embedded in the limiting groove. The driving mechanism is installed in the frame 1 to drive the mounting seat 6 and the mounting ring 8 to move in an offset manner.

[0040] In some technical solutions of the present invention, there are two groups of clamping mechanisms, and the two groups of clamping mechanisms are symmetrically arranged in the frame 1.

[0041] In some technical schemes of the present invention, the driving mechanism includes a first transmission belt 2, a second transmission belt 3 and two transmission rods 26 rotatably arranged in the frame 1 through bearings, the transmission rods 26 are fixedly mounted with first transmission wheels 14 through pins, the transmission rods 26 are rotatably mounted with second transmission wheels 25, the first transmission belt 2 is wound around the two first transmission wheels 14, the second transmission belt 3 is wound around the second transmission wheel 25, the mounting seat 6 is mounted on the first transmission wheel 14, the mounting ring 8 is mounted on the second transmission belt 3, and a locking mechanism for locking the first transmission belt 2 and the second transmission belt 3 is provided between the two.

[0042] A driving motor connected to one of the driving rods 26 is provided on the outer side wall of the frame 1. The number of the driving mechanisms is also two groups, which are used to drive the two groups of clamping mechanisms to move respectively.

[0043] In some technical solutions of the present invention, the locking mechanism includes a locking rod 29, which is slidably arranged on the side wall opposite to the first conveyor belt 2 and the second conveyor belt 3, and an adjustment spring 30 connected to the first conveyor belt 2 is sleeved on the locking rod 29, and a plurality of locking grooves 28 adapted to the locking rod 29 are opened on the side wall opposite to the first conveyor belt 2 of the second conveyor belt 3.

[0044] Working principle of the clamping mechanism and driving mechanism:

[0045] First, the driving motor is started to force the transmission rod 26 connected thereto to drive the first conveyor belt 2 to rotate clockwise in the frame 1. At the same time, the first conveyor belt 2 will push the second conveyor belt 3 to rotate clockwise in the frame 1 through the locking rod 29 in the locking mechanism, so that the clamping mechanism gradually approaches the clamping mechanism; and after moving a certain distance, the locking rod 29 installed on the first conveyor belt 2 withdraws from the locking groove 28, and the locking rod 29 continues to move along the extension direction of the frame 1 until the end of the limit cylinder 7 in the clamping mechanism abuts against the mounting ring 8 and stops moving. At this time, the locking rod 29 and the locking groove 28 form a mutually misaligned state;

[0046] Subsequently, the operator clamps the capacitor 15 in the clamping area formed between the two clamping plates 16. After the capacitor 15 gradually enters the clamping area, the two leads of the capacitor 15 pass through the gap between the limit block 34 and the clamping plate 16 and enter the circular structure formed by surrounding a plurality of clamping arms 10. Subsequently, the operator starts the driving motor, forcing the transmission rod 26 connected to it to drive the first conveyor belt 2 to rotate counterclockwise in the frame 1. In the above process, the first conveyor belt 2 first drives the mounting seat 6 to drive the limit cylinder 7 to move a certain distance first. At this time, the limit protrusion set in the limit cylinder 7 gradually moves out of the limit groove from the state of being embedded in the limit groove, that is, the large diameter end of the limit protrusion is used to apply a force to the clamping arm 10 set in the mounting ring 8. The thrust causes the clamping arm 10 to gradually contact the lead, so that the lead can be clamped. At the same time, the locking rod 29 in the locking mechanism is embedded in the locking groove 28 on the second conveyor belt 3. Then the first conveyor belt 2 will drive the first conveyor belt 2 to move together in the direction of the detection mechanism 4. At this time, the mounting seat 6 causes the detection end of the detection mechanism 4 to be relatively displaced on the frame 1, and exerts pressure on the detection end of the detection mechanism 4. The force measurement count is displayed on the detection mechanism 4, so that the traction force generated when the lead of the capacitor 15 is pulled by the above-mentioned structure can be detected. When the first conveyor belt 2 drives the above-mentioned structure to continue to move away from the clamping mechanism, the traction force of the above-mentioned structure on the lead of the capacitor 15 gradually increases, thereby checking whether the lead of the capacitor 15 has cold soldering or other quality problems.

[0047] In some technical solutions of the present invention, a mounting chamber 19 is provided in the mounting seat 6, a wedge-shaped guide groove 23 is provided in the mounting chamber 19, a guide block 22 is a wedge-shaped block, and the guide block 22 is slidably arranged in the guide groove 23. An electric push rod 21 is provided in the mounting chamber 19, and the telescopic end of the electric push rod 21 is connected to the guide block 22, and a guide ring 8 is provided to be slidably arranged on the outer side wall of the second conveyor belt 3 along the width direction of the second conveyor belt 3. In this way, the limiting cylinder 7 in the clamping mechanism and the multiple clamping arms 10 placed in the limiting cylinder 7 can be controlled to move in the width direction of the frame 1 on the frame 1, thereby changing the relative position of the clamping mechanism on the frame 1, so as to clamp the leads on capacitors 15 of different sizes.

[0048] In some technical solutions of the present invention, the third transmission belt 13 is rotatably provided on both sides of the operating platform 12, and the first auxiliary roller 18 and the second auxiliary roller 20 which are transmission-connected to the third transmission belt 13 are rotatably provided at both ends of the operating platform 12, and the third transmission wheel 27 which is transmission-connected to the third transmission belt 13 is sleeved on the transmission rod 26, and the third transmission wheel 27 is rotationally connected to the inner wall of the frame 1, and a plurality of ratchet teeth 32 are equidistantly provided on the inner wall of the third transmission wheel 27 along its circumference, and a sink groove is provided on the outer wall of the transmission rod 26, and a locking tooth 31 is rotationally provided in the sink groove, and a part of the locking tooth 31 is embedded between any two adjacent ratchet teeth 32. A part of the third transmission belt 13 is placed between the opposite side walls of the two clamping plates 16.

[0049] When the transmission rod 26 drives the first transmission belt 2 to rotate clockwise in the frame 1, so that the mounting seat 6 installed on the first transmission belt 2 approaches the clamping mechanism, the transmission rod 26 rotating clockwise will force the third transmission wheel 27 to rotate clockwise on the frame 1 through the locking tooth 31, thereby driving the third transmission belt 13 connected to it to rotate clockwise on the operating table 12, so that the capacitor 15 placed in the two clamping areas is withdrawn from the clamping area, which is convenient for quickly taking the capacitor 15 out of the clamping mechanism after the measurement of the capacitor 15 is completed; when the transmission rod 26 drives the first transmission belt 2 to rotate counterclockwise in the frame 1, the third transmission wheel 27 idles on the transmission rod 26, which will not affect the movement state of the capacitor 15 in the clamping mechanism.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
