Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor testing technology, and in particular to a capacitor rack auxiliary loading and unloading tooling. Background Technology
[0002] A capacitor holder is a fixture used to simultaneously clamp and position multiple capacitors. Through the coordinated operation of multiple clamps, it achieves the clamping and precise positioning of multiple capacitors, providing a stable platform for efficient testing of multiple capacitors. Each clamp is equipped with an openable double-clamp structure, allowing for clamping and releasing of the capacitors through a pressing operation.
[0003] However, in the traditional operating mode, testers need to press the opening and closing tabs of the fixture one by one and place multiple capacitors into multiple fixtures in sequence, so that the opening and closing tabs of the fixtures can hold multiple capacitors respectively to complete the loading of multiple capacitors; after the test, the testers have to operate the opening and closing tabs of the fixtures in sequence to release the multiple capacitors to complete the unloading of multiple capacitors. This repetitive loading and unloading method of pressing the opening and closing tabs consumes a lot of time, so it is not conducive to improving the efficiency of testing multiple capacitors. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a capacitor rack auxiliary loading and unloading fixture, which can reduce the time spent loading and unloading multiple capacitors, thereby improving the efficiency of testing multiple capacitors.
[0005] According to an embodiment of the present invention, a capacitor array auxiliary loading and unloading fixture includes a worktable, a first capacitor array, a second capacitor array, and a pressing device. The worktable is provided with a first positioning groove and a second positioning groove; the first capacitor array is disposed in the first positioning groove, and the first capacitor array includes multiple first tooling clamps distributed along the front-back direction, each of the multiple first tooling clamps including a first double-clamp structure for clamping capacitors; the second capacitor array is disposed in the second positioning groove, and the second capacitor array includes multiple second tooling clamps distributed along the front-back direction, each of the multiple second second tooling clamps including a second double-clamp structure for clamping the capacitors; the pressing device is disposed on the worktable, and the pressing device is used to simultaneously press multiple first double-clamp structures and multiple second double-clamp structures.
[0006] It has at least the following beneficial effects:
[0007] The first and second positioning slots on the worktable are used to place the first and second capacitor banks, respectively. The inner wall of the first positioning slot positions the first capacitor bank, and the inner wall of the second positioning slot positions the second capacitor bank, thus ensuring accurate positioning of both on the worktable. When multiple capacitors need to be tested, the pressing device simultaneously presses the first double-clamp structure in the multiple first fixtures of the first capacitor bank and the second double-clamp structure in the multiple second fixtures of the second capacitor bank, keeping both the first and second double-clamp structures open. The tester then sequentially places multiple capacitors to be tested into the multiple first and second fixtures to complete the loading of multiple capacitors. Then, the pressing device simultaneously releases the multiple first and second double-clamp structures, allowing both structures to hold the capacitors. After testing, the pressing device simultaneously presses multiple first double-clamp structures and multiple second double-clamp structures, causing each structure to release multiple capacitors. The tester can then remove the tested capacitors from the multiple first and second fixture clamps, completing the unloading process. This capacitor rack-assisted unloading fixture eliminates the need for repetitive pressing of the first and second double-clamp structures, shortening the unloading time and thus improving the efficiency of testing multiple capacitors.

[0030] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional 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.
[0031] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.
[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0033] refer to Figures 1 to 5 This utility model discloses an auxiliary loading and unloading fixture for capacitor racks, including a worktable 400, a first capacitor rack 100, a second capacitor rack 200, and a pressing device 300.
[0034] The worktable 400 is provided with a first positioning groove 411 and a second positioning groove 421; a first capacitor rack 100 is disposed in the first positioning groove 411, and the first capacitor rack 100 includes a plurality of first tooling clamps 110 distributed in the front-back direction, and each of the plurality of first tooling clamps 110 includes a first double clamping structure 120 for clamping capacitors; a second capacitor rack 200 is disposed in the second positioning groove 421, and the second capacitor rack 200 includes a plurality of second tooling clamps distributed in the front-back direction, and each of the plurality of second tooling clamps includes a second double clamping structure for clamping capacitors; a pressing device 300 is disposed on the worktable 400, and the pressing device 300 is used to simultaneously press the plurality of first double clamping structures 120 and the plurality of second double clamping structures.
[0035] Understandably, the first positioning groove 411 and the second positioning groove 421 on the worktable 400 are respectively used to place the first capacitor bank 100 and the second capacitor bank 200, so that the inner wall of the first positioning groove 411 can position the first capacitor bank 100, and the inner wall of the second positioning groove 421 can position the second capacitor bank 200, thereby ensuring that the first capacitor bank 100 and the second capacitor bank 200 are accurately positioned on the worktable 400. When multiple capacitors need to be tested, the pressing device 300 can simultaneously press the first double clamping structure 120 in the multiple first tooling clamps 110 of the first capacitor bank 100 and the second double clamping structure in the multiple second tooling clamps of the second capacitor bank 200, so that the multiple first double clamping structures 120 and the multiple second double clamping structures can be kept open at the same time. Then, the tester puts multiple capacitors to be tested into the multiple first tooling clamps 110 and the multiple second tooling clamps in sequence to complete the loading of multiple capacitors. Then, the pressing device 300 simultaneously releases multiple first double-clamp structures 120 and multiple second double-clamp structures, allowing each of these structures to hold the capacitor. After testing, the pressing device 300 simultaneously presses the multiple first double-clamp structures 120 and multiple second double-clamp structures, causing each structure to release a capacitor. The tester can then remove the tested capacitors from the multiple first fixture clamps 110 and multiple second fixture clamps, completing the unloading of the capacitors. This capacitor rack-assisted unloading fixture eliminates the need for the tester to repeatedly press the multiple first double-clamp structures 120 and multiple second double-clamp structures, shortening the unloading time and thus improving the efficiency of testing multiple capacitors.
[0036] refer to Figure 2 and Figure 3The pressing device 300 includes a first push plate 310, a second push plate 320, a third push plate 330, a fourth push plate 340, and a linear drive mechanism. The first push plate 310, the second push plate 320, and the fourth push plate 340 are all slidably connected to the worktable 400 in the left-right direction. The third push plate 330 is disposed on the worktable 400. The first push plate 310, the second push plate 320, the third push plate 330, and the fourth push plate 340 are arranged sequentially from left to right. The first push plate 310 and the second push plate 320... The first and second push plates are respectively located on the left and right sides of the first positioning groove 411, and the third push plate 330 and the fourth push plate 340 are respectively located on the left and right sides of the second positioning groove 421. The linear drive mechanism can drive the first push plate 310 and the second push plate 320 to move closer to each other and drive the fourth push plate 340 to move closer to the third push plate 330, so that the first push plate 310 and the second push plate 320 simultaneously press multiple first double clamping structures 120, and the third push plate 330 and the fourth push plate 340 simultaneously press multiple second double clamping structures. It is understood that the first capacitor bank 100 is located between the first push plate 310 and the second push plate 320, and the second capacitor bank 200 is located between the first push plate 310 and the second push plate 320. The linear drive mechanism can drive the first push plate 310 and the second push plate 320 to move closer to each other and can drive the fourth push plate 340 to move closer to the third push plate 330, so that the first push plate 310 and the second push plate 320 simultaneously press the first double clamping structure 120 of multiple first tooling clamps 110, and also cause the third push plate 330 and the fourth push plate 340 to simultaneously press the second double clamping structure of multiple second tooling clamps. The linear drive mechanism can drive the first push plate 310 and the second push plate 320 away from each other and can drive the fourth push plate 340 away from the third push plate 330, so that the first push plate 310 and the second push plate 320 simultaneously release the first double clamping structure 120 of multiple first tooling clamps 110, and also cause the third push plate 330 and the fourth push plate 340 to simultaneously release the second double clamping structure of multiple second tooling clamps.
[0037] refer to Figure 2 and Figure 3The linear drive mechanism includes a first linear drive member 350 and a second linear drive member 360. Both the first linear drive member 350 and the second linear drive member 360 are mounted on the worktable 400. The first linear drive member 350 can drive the first push plate 310 to move to the right, and the second linear drive member 360 can drive the second push plate 320 and the fourth push plate 340 to move to the left at the same time, so that the first push plate 310 and the second push plate 320 simultaneously press multiple first double clamping structures 120, and the third push plate 330 and the fourth push plate 340 simultaneously press multiple second double clamping structures. Understandably, when multiple first double-clamp structures 120 and multiple second double-clamp structures need to be pressed, the first linear drive 350 and the second linear drive 360 are activated simultaneously. This causes the first linear drive 350 to move the first push plate 310 to the right, and the second linear drive 360 to move the second push plate 320 and the fourth push plate 340 to the left simultaneously. Consequently, the first push plate 310 and the second push plate 320 simultaneously press down on the multiple first double-clamp structures 120, and the third push plate 330 and the fourth push plate 340 simultaneously press down on the multiple second double-clamp structures. When multiple first double-clamp structures 120 and multiple second double-clamp structures need to be released, the first linear drive 350 causes the first push plate 310 to move to the left, and the second linear drive 360 causes the second push plate 320 and the fourth push plate 340 to move to the right simultaneously.
[0038] refer to Figure 2 and Figure 3The capacitor rack auxiliary loading and unloading fixture also includes a first support plate 410, a second support plate 420, and a mounting plate 370. The first support plate 410 is located on the worktable 400 and between the first push plate 310 and the second push plate 320. A first positioning groove 411 is located on the first support plate 410. The second support plate 420 is located on the worktable 400 and between the third push plate 330 and the fourth push plate 340. A second positioning groove 421 is located on the second support plate 420. The mounting plate 370 is slidably connected to the worktable 400 in the left-right direction and is located between the second support plate 420 and the worktable 400. The third push plate 330 and the fourth push plate 340 are both located on the mounting plate 370. The output end of the first linear drive 350 is connected to the first push plate 310, and the output end of the second linear drive 360 is connected to the fourth push plate 340. Understandably, the first linear drive 350 can drive the first push plate 310 to move to the right, and the second linear drive 360 can drive the fourth push plate 340 to move to the left. Since the second push plate 320 and the fourth push plate 340 are both mounted on the mounting plate 370, the second push plate 320 and the fourth push plate 340 can move to the left together. At this time, the first push plate 310 and the second push plate 320 approach each other, and the fourth push plate 340 approaches the third push plate 330. This allows the first push plate 310 and the second push plate 320 to press multiple first double clamping structures 120 at the same time, and also allows the third push plate 330 and the fourth push plate 340 to press multiple second double clamping structures at the same time.
[0039] In this embodiment of the utility model, the first push plate 310, the second push plate 320 and the mounting plate 370 are all slidably connected to the worktable 400 in the left and right directions by a slider and slide rail assembly. The slider and slide rail assembly is a common sliding assembly, which will not be described in detail here.
[0040] In one embodiment of this utility model, the first linear drive 350 and the second linear drive 360 are respectively a first cylinder and a second cylinder. The first cylinder is located on the left side of the first push plate 310, and its cylinder body is located on the worktable 400. The piston rod of the first cylinder is connected to the first push plate 310. The second cylinder is located on the right side of the fourth push plate 340, and its cylinder body is located on the worktable 400. The piston rod of the second cylinder is connected to the fourth push plate 340. In another embodiment of this utility model, the first linear drive 350 and the second linear drive 360 can be respectively a first lead screw and nut drive and a second lead screw and nut drive. The lead screw and nut drive is a common linear drive, which will not be described further here.
[0041] refer to Figure 2 and Figure 3The first support plate 410 is provided with two first guide posts 412, which are respectively located on the left and right sides of the first positioning groove 411. The upper end of each of the two first guide posts 412 is provided with a first guide slope 413, and the included angle formed by the two first guide slopes 413 is upward. The second support plate 420 is provided with two second guide posts, which are respectively located on the left and right sides of the second positioning groove 421. The upper end of each of the two second guide posts is provided with a second guide slope, and the included angle formed by the two second guide slopes is upward. Understandably, during the process of the tester placing the first capacitor bank 100 into the first positioning slot 411, the first guide slopes 413 at the upper ends of the two first guide posts 412 can abut against the first capacitor bank 100. The two first guide slopes 413 can guide the first capacitor bank 100, making it easier for the tester to place the first capacitor bank 100 into the first positioning slot 411. Furthermore, the first guide posts 412 can abut against the first capacitor bank 100 in the first positioning slot 411, enabling the two first guide posts 412 to perform a positioning function on the first capacitor bank 100 in the left-right direction. The function of the second guide post is the same as that of the first guide post 412, and will not be further elaborated here. In this embodiment of the present invention, the first support plate 410 has two first guide posts 412 at both its front and rear ends, and the second support plate 420 has two second guide posts at both its front and rear ends, and will not be further elaborated here.
[0042] refer to Figure 4 The first capacitor bank 100 includes a first substrate 130, and a plurality of first tooling clamps 110 are evenly distributed on the first substrate 130 along the front-back direction. The first substrate 130 is disposed within a first positioning groove 411. The second capacitor bank 200 includes a second substrate, and a plurality of second tooling clamps are evenly distributed on the second substrate along the front-back direction. The second substrate is disposed within a second positioning groove 421. First gripping portions 131 are provided at both the front and rear ends of the first substrate 130, and second gripping portions are provided at both the front and rear ends of the second substrate. It is understood that testers can move the first capacitor bank 100 by grasping the first gripping portions 131 at both the front and rear ends of the first substrate 130. Similarly, testers can move the second capacitor bank 200 by grasping the second gripping portions at both the front and rear ends of the second substrate, improving the convenience for testers to move the first capacitor bank 100 and the second capacitor bank 200. (Reference) Figure 1 The workbench 400 is equipped with multiple self-locking casters 430 at its bottom, allowing it to move on the ground. These casters enable easy movement of the workbench 400, allowing testers to flexibly adjust the position of the capacitor rack auxiliary loading and unloading fixture according to actual needs, thus improving the flexibility of its use. The self-locking casters 430 are common types of wheels that can rotate freely and lock themselves; further details will not be provided here.
[0043] This example uses the first capacitor bank 100 for illustration. (Reference) Figures 5 to 7 The first capacitor bank 100 includes a first substrate 130 and a plurality of first tooling clamps 110, which are evenly distributed on the first substrate 130 in the front-back direction. Each first tooling clamp 110 includes a first clamp body, a first double-clamp structure 120, and a first conductive component. The first double-clamp structure 120 includes two first opening and closing clamps, which are respectively hinged to the left and right sides of the first clamp body. A spring is provided between each of the two first opening and closing clamps and the first clamp body. The two springs are used to drive the upper ends of the two first opening and closing clamps to move closer together, so that the upper ends of the two first opening and closing clamps can clamp the capacitor. Here, one of the first tooling clamps 110 is used as an example. A first push plate 310 and a second push plate 320 move closer together, so that the first push plate 310 and the second push plate 320 can respectively press the lower ends of the two first opening and closing clamps, thereby causing the upper ends of the two first opening and closing clamps to open. Next, the tester places the capacitor into the first clamping slot on the first clamp body. The first push plate 310 and the second push plate 320 move away from each other and disengage from the two first opening and closing clamping pieces. The upper ends of the two first opening and closing clamping pieces move closer together under the action of the spring and clamp the capacitor to complete the loading of the capacitor. After the capacitor has completed the test, the first push plate 310 and the second push plate 320 move closer together and press the lower ends of the two first opening and closing clamping pieces respectively. The upper ends of the two first opening and closing clamping pieces open and release the capacitor. At this time, the tester can remove the capacitor from the first clamping slot to complete the unloading of the capacitor. The first conductive component is used to realize the electrical conduction between the capacitor and the test system, which will not be described in detail here. The structure and principle of the first capacitor rack 100 are common fixtures in the field of capacitor testing, and the structure and loading and unloading process of the second capacitor rack 200 are the same as those of the first capacitor rack 100, which will not be described in detail here.
[0044] refer to Figure 7 The first push plate 310 has multiple first push rods 311 evenly distributed along its front-back direction on the side facing the second push plate 320. The first push plate 310 abuts against the lower ends of the first opening and closing clamping pieces on the left side of the multiple first tooling clamps 110 through the multiple first push rods 311. The second push plate 320 has multiple second push rods 321 evenly distributed along its front-back direction on the side facing the first push plate 310. The second push plate 320 abuts against the lower ends of the first opening and closing clamping pieces on the right side of the multiple first tooling clamps 110 through the multiple second push rods 321. The third push plate 330 has third push rods evenly distributed along its front-back direction on the side facing the fourth push plate 340, and the fourth push plate 340 has fourth push rods evenly distributed along its front-back direction on the side facing the third push plate 330. Further details are omitted here.
