Description

Technical Field

[0001] This utility model relates to the field of battery production, and more specifically, to a thickness testing fixture. Background Technology

[0002] After the battery is assembled, its thickness needs to be measured. Since the thickness standard is different at different locations of the battery, it is necessary to measure different parts of the battery separately. The existing measurement method is to use different equipment to measure different locations. After completing the thickness measurement of one location of the battery, the battery needs to be transferred to another device and repositioned, measured, and unloaded. The operation is complicated and the steps are cumbersome, which leads to a decrease in production line efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a thickness testing fixture that can simultaneously measure the thickness of a battery at multiple locations, effectively simplifying the measurement operation and improving measurement efficiency.

[0004] A thickness testing fixture includes: a support platform for supporting a product to be tested; a translation component connected to the support platform for driving the support platform to move horizontally; at least two measuring components disposed at one end of the movement path of the support platform, each measuring component including a pressure block and a measuring element, the pressure block being configured to be liftable, the measuring element being mounted above the pressure block, and the test end of the measuring element being connected to the pressure block; and a lifting component for lifting the pressure block to move it away from the support platform.

[0005] In the above technical solution, by setting at least two measuring components, the thickness of the battery at different locations can be measured simultaneously, thereby simplifying the measurement steps and improving measurement efficiency. Specifically, during measurement, the battery to be measured is placed on a support platform. The translation component moves the support platform closer to the measuring components. Then, the lifting component simultaneously releases the pressure blocks of multiple measuring components. The pressure blocks press down and abut against the corresponding battery surface. The measuring components measure the thickness of the battery at the corresponding location based on the height of the pressure block. The lifting component then lifts the pressure block, separating it from the support platform. The translation component drives the support platform to reset, thus completing the detection. The overall structure is reasonable, the operation is convenient, and the measurement efficiency is effectively improved.

[0006] Furthermore, one end of the translation component is provided with a vertical plate, and the vertical plate is provided with a vertically movable mounting base, and the pressure block is connected to the mounting base.

[0007] In the above technical solution, the pressure block is slidably connected to the upright plate through the mounting base, the overall structure is simple, and the stability of the pressure block movement can be guaranteed.

[0008] Furthermore, the mounting base extends outward to form a drive arm, and the output end of the lifting member is connected to a support plate, which abuts against the lower end of the drive arm.

[0009] In the above technical solution, the lifting component can simultaneously abut against the drive arms of multiple measuring components through the abutment plate, thereby realizing the simultaneous release of multiple pressure blocks or the simultaneous driving of multiple pressure blocks to rise.

[0010] Furthermore, the upright plate is provided with a counterweight assembly corresponding to each of the measuring components. The counterweight assembly includes a counterweight and a swing arm. The swing arm is rotatably connected to the upright plate, and the two ends of the swing arm are respectively connected to the mounting base and the counterweight.

[0011] In the above technical solution, in order to improve the measurement accuracy, it is necessary to ensure that the pressure block is in close contact with the battery surface. Therefore, the pressure block needs to have a certain weight. By setting a counterweight component, the force required by the lifting component to lift the pressure block can be reduced, thereby extending the service life of the lifting component while ensuring the measurement accuracy.

[0012] Furthermore, the mounting base is provided with a cam, and the end of the swing arm near the mounting base is provided with a groove, the cam extends into the groove and can move along the extension direction of the groove.

[0013] In the above technical solution, the mounting base cooperates with the groove of the swing arm through the cam, so that the swing arm can swing with the rise and fall of the mounting base. The counterweight and the mounting base form a lever structure through the swing arm, thereby reducing the force required for the lifting component to lift the pressure block.

[0014] Furthermore, the mounting base is provided with a through hole, and the test end of the measuring element passes through the through hole.

[0015] In the above technical solution, the mounting base is provided with a through hole, which facilitates the connection between the measuring component and the pressure block.

[0016] Furthermore, the side of the pressure block facing the support platform is formed as a bearing surface for abutting against the product surface.

[0017] In the above technical solution, the supporting surface can abut against the surface to be measured, thereby measuring the overall height of the surface and improving the accuracy of the measurement.

[0018] Furthermore, the translation component includes a translation drive and a guide rail, the support platform is slidably connected to the guide rail, and the output end of the translation drive is connected to the support platform.

[0019] In the above technical solution, the translation drive can drive the carrier platform to slide linearly along the guide rail, thereby allowing the carrier platform to switch between the operation end and the measurement end.

[0020] Furthermore, the support platform is provided with positioning slots for placing products.

[0021] In the above technical solution, the positioning groove can fix the product and ensure the stability of the product during measurement.

[0022] Furthermore, a barcode scanning component is installed above the moving path of the carrying platform.

[0023] In the above technical solution, the barcode scanning component can scan the measured product, facilitating the traceability of the product's test results.

[0024] Compared with existing technologies, the advantages of this invention are: by setting at least two measuring components, the thickness of the battery at different locations can be measured simultaneously, thereby simplifying the measurement steps and improving measurement efficiency. Specifically, during measurement, the battery to be measured is placed on a support platform. The translation component moves the support platform closer to the measuring component. Then, the lifting component releases the pressure block, which presses down and abuts against the corresponding battery surface. The measuring component measures the thickness of the battery at the corresponding location based on the height of the pressure block. The lifting component then raises the pressure block, separating it from the support platform. The translation component drives the support platform to reset, thus completing the detection. The overall structure is reasonable, the operation is convenient, and the measurement efficiency is effectively improved. Attached Figure Description

Detailed Implementation

[0031] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0032] Please refer to Figures 1 to 4 In a preferred embodiment, the thickness testing fixture of this invention mainly includes a support platform 1, a translation component 2, at least two measuring components 3, and a lifting component 4. The support platform 1 is used to support the product to be tested. The translation component 2 is connected to the support platform 1 and is used to drive the support platform 1 to move horizontally. The measuring component 3 is located at one end of the moving path of the support platform 1, and includes a pressure block 31 and a measuring element 32. The pressure block 31 is configured to be liftable, and the measuring element 32 is mounted above the pressure block 31, with its test end connected to the pressure block 31. The lifting component 4 is used to lift the pressure block 31 so that the pressure block 31 is away from the support platform 1.

[0033] For example, the measuring element 32 can be a micrometer, which is mounted on a gantry frame above the moving path of the support platform 1. Its test end extends vertically downward and is connected to the pressure block. The measuring elements 32 of multiple measuring components 3 are arranged side by side. In specific measurement, the initial position of the support platform 1 is located at the end away from the measuring components 3. The battery to be measured is placed on the support platform 1. The translation component 2 moves the support platform 1 to the end closer to the measuring components 3. Then, the lifting component 4 releases the pressure blocks 31 of multiple measuring components 3 at the same time. The pressure blocks 31 press down and abut against the corresponding battery surface. The measuring element 32 measures the thickness of the battery at the corresponding position by the height of the corresponding pressure block 31. Then, the lifting component 4 lifts the pressure block 31, separating the pressure block 31 from the support platform 1. The translation component 2 drives the support platform 1 to reset, thereby completing the detection. The overall structure is reasonable, the operation is convenient, and the measurement efficiency is effectively improved. This embodiment, by setting at least two measuring components 3, can simultaneously measure the thickness of different positions of the battery, thereby simplifying the measurement steps and improving the measurement efficiency.

[0034] Please refer to Figure 1 and Figure 2 One end of the translation component 2 is provided with a vertical plate 5, and a vertically movable mounting base 6 is provided on the vertical plate 5. The pressure block 31 is connected to the mounting base 6. For example, the vertical plate 5 is located on the surface of a platform and at one end of the translation component 2. The mounting base 6 is slidably connected to the vertical plate 5, and the pressure block 31 is connected to the mounting base 6 by bolts. The mounting base 6 can slide vertically relative to the vertical plate 5, thereby driving the pressure block 31 to rise and fall vertically. The pressure block 31 is slidably connected to the vertical plate 5 via the mounting base 6. The overall structure is simple and ensures the stability of the movement of the pressure block 31.

[0035] In this embodiment, the mounting base 6 extends outward to form a drive arm 61, and the output end of the lifting member 4 is connected to a support plate 41, which abuts against the lower end of the drive arm 61. Exemplarily, the drive arm 61 is located on the surface of the mounting base 6 near the upright plate 5 and passes through the upright plate 5. The lifting member 4 can employ an existing linear drive device, such as a cylinder. The support plate 41 is formed as a long plate or rod, connected to the output end of the lifting member 4, and its upper end abuts against the lower end of the drive arm 61. The lifting member 4 can drive the support plate 41 to rise and fall vertically. When the support plate 41 rises, it drives the mounting base 6 to rise via the drive arm 61, thereby moving the pressure block 31 away from the bearing platform 1. When the support plate 41 falls, under the weight of the pressure block 31, the mounting base 6 and the pressure block 31 move downward, pressing the pressure block 31 firmly against the product surface. Understandably, the drive arms 61 of multiple mounting bases 6 can simultaneously abut against the support plate 41. In this way, multiple pressure blocks 31 can be released or driven to rise simultaneously by a single lifting member 4.

[0036] Please refer to Figure 4 The upright plate 5 is equipped with counterweight components 7 corresponding to the measuring components 3. The counterweight component 7 includes a counterweight 71 and a swing arm 72. The swing arm 72 is rotatably connected to the upright plate 5, and its two ends are connected to the mounting base 6 and the counterweight 71, respectively. It should be noted that to improve measurement accuracy, it is necessary to ensure that the pressure block 31 is in close contact with the battery surface. Therefore, the pressure block 31 needs to have a certain weight. Since the combined weight of multiple pressure blocks 31 is relatively large, the lifting component 4 needs to have greater force to lift multiple pressure blocks 31 simultaneously. This places higher demands on the lifting component 4, increasing costs, and also increases wear on the lifting component 4, reducing its service life. Therefore, this embodiment reduces the force required by the lifting component 4 to lift the pressure block 31 by setting the counterweight component 7, thereby extending the service life of the lifting component 4 while ensuring measurement accuracy.

[0037] Specifically, the mounting base 6 is provided with a cam 62, and the end of the swing arm 72 near the mounting base 6 is provided with a groove 721. The cam 62 extends into the groove 721 and can move along the extension direction of the groove 721. The mounting base 6 cooperates with the groove 721 of the swing arm 72 through the cam 62, so that the swing arm 72 can swing with the rise and fall of the mounting base 6. The counterweight 71 and the mounting base 6 form a lever structure through the swing arm 72, thereby reducing the force required for the lifting member 4 to lift the pressure block 31.

[0038] In this embodiment, the mounting base 6 is provided with a through hole, through which the test end of the measuring element 32 passes. By providing a through hole in the mounting base 6, the measuring element 32 can be easily connected to the pressure block 31.

[0039] The pressure block 31 is formed on the side facing the support platform 1 as a bearing surface for abutting against the product surface. The bearing surface can abut against the surface to be measured, thereby measuring the overall height of the surface and improving the accuracy of the measurement.

[0040] Please refer to Figure 3 The translation component 2 includes a translation drive 21 and a guide rail 22. The support platform 1 is slidably connected to the guide rail 22, and the output end of the translation drive 21 is connected to the support platform 1. The translation drive 21 can be an existing linear drive device, such as a rodless cylinder, whose output end is connected to the support platform 1, enabling the support platform 1 to slide linearly along the guide rail 22, thereby switching the support platform 1 between the operation end and the measurement end.

[0041] In this embodiment, the support platform 1 is provided with a positioning groove for placing the product. The positioning groove can fix the product and ensure the stability of the product during measurement.

[0042] A barcode scanning component 8 is mounted above the moving path of the carrying platform 1. The barcode scanning component 8 can be an existing one, and it can scan the barcodes on the measured products, facilitating traceability of the product test results.
