Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and mainly to a battery pack testing machine. Background Technology

[0002] Early testing equipment mostly used fixed probe modules, with physical interfaces designed for the size and terminal position of specific battery packs. Traditional equipment required custom probe modules for each battery model, and the production line had to be shut down to replace the hardware when changing models, resulting in reduced production line efficiency. This rigid design made it difficult for the equipment to adapt to the rapid switching requirements of different battery pack specifications.

[0003] A quick-connection device for battery pack testing, as disclosed in utility model application number CN202121108509.X, includes: a conductive block, a first pressure block, and a second pressure block; the first and second pressure blocks slide via a guide structure; the first pressure block and the conductive block are connected by a first positioning post and a first positioning hole, and the second pressure block and the conductive block are connected by a second positioning post and a second positioning hole; a first wire lug electrically connected to the battery pack is mounted on the first positioning post, and a second wire lug electrically connected to a charging / discharging device is mounted on the second positioning post; the conductive block is magnetically attached to the first and second pressure blocks. The first pressure block presses the first wire lug onto one end of the conductive block, and the second pressure block presses the second wire lug onto the other end of the conductive block, thereby electrically connecting the battery pack to the charging / discharging device and accommodating different battery packs. This device makes connecting the battery pack to the charging / discharging device faster and more convenient, allows for quick replacement of the battery pack to be tested, and increases testing efficiency.

[0004] However, the existing technology still has shortcomings: 1. The battery pack is not fixed stably, which can easily cause the battery pack to shift and shake during the test, resulting in poor contact or data acquisition errors, and ultimately causing product quality problems. 2. Fixed battery pack testing equipment is not flexible, and the battery pack must be moved and placed on the equipment.

[0005] Therefore, there is an urgent need for a battery pack testing machine that is robust, easy to test, and flexible. Utility Model Content

[0006] To address the above issues, a robust, easy-to-test, and flexible battery pack testing machine was developed. Through a positioning module with clamping components and positioning blocks, as well as an adjustable voltage sampling module and testing module, the machine's versatility is improved, making it suitable for battery packs of different specifications and effectively increasing production efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A battery pack testing machine, comprising: The testing equipment includes a voltage sampling module, a testing module, and a positioning module on its worktable. The voltage sampling module is used to collect voltage from the battery pack, the detection module is used to detect the battery pack, and the positioning module is used to fix the battery pack. The positioning module includes a battery platform, a positioning block, and a clamping assembly. The battery platform is used to place the battery pack. The positioning block is located at any corner of the battery platform. The clamping assembly is symmetrically arranged with the positioning block and is used to clamp and securely position the battery packs of different specifications.

[0008] As an improvement, the workbench is provided with several sets of parallel strip holes, which are distributed along the width direction of the workbench.

[0009] As an improvement, the clamping assembly has two sets located on both sides of the battery pack. The clamping assembly includes a base, a rack and pinion rail, and a sliding block. The base moves in conjunction with the rack and pinion rail through an adjusting component. The base is slidably disposed in the strip hole through a reinforcing member. The rack and pinion rail is provided with several sets of toothed grooves. A sliding groove is provided on a protrusion on one side of the base. The sliding block is connected to the sliding block through the sliding groove by a tightening component.

[0010] As an improvement, the positioning block is L-shaped and is positioned to abut against the adjacent two sides of the battery pack.

[0011] As an improvement, the adjustment component includes a fixed block, a lead screw, and a toothed block. The fixed block is fixedly connected to the base, the lead screw is fixedly connected to the fixed block, the end of the lead screw is rotatably connected to the toothed block, the end of the toothed block is provided with teeth, the teeth mesh with the tooth groove, and a knob is provided on the top of the toothed block.

[0012] As an improvement, the voltage sampling module includes a fixed base, a support tube, and a probe. The fixed base is fixed to the workbench and has a sliding hole. The support tube is slidably connected to the sliding hole. An arc-shaped sliding hole is provided on the side plate of the support tube. The probe is connected to the side plate by bolts. The bolt at the bottom of the probe passes through the arc-shaped sliding hole and can be adjusted for tightness by swinging.

[0013] As an improvement, the detection module includes a probe and a cylinder. The cylinder is fixedly connected to the workbench via a connecting seat, and the probe is fixedly connected to the output end of the cylinder.

[0014] As an improvement, the detection device also includes a temperature sensor mounted on a support base. The support base includes two sets of parallel vertical rods and a horizontal rod connected to the two sets of vertical rods. The temperature sensor can be adjusted and slidably mounted on the horizontal rod by a tensioning element, and the horizontal rod can be raised and lowered on the vertical rod by an adjusting element.

[0015] As an improvement, the bottom of the workbench of the testing equipment is also provided with a support frame. The support frame is a frame structure formed by welding several sets of longitudinal beams and transverse beams. The bottom of the support frame is provided with several sets of sliding support wheels, and the support wheels are fitted with anti-slip rubber pads.

[0016] The beneficial effects of this utility model are as follows: (1) The L-shaped positioning in this utility model forms a fixed corner reference by contacting the adjacent sides of the battery pack. Combined with the symmetrical force of the two sets of parallel clamping components, it solves the problem of traditional positioning having no reference and being easy to deviate, and forms a three-point positioning effect to ensure that the battery pack does not shake. (2) The base provided in this utility model can move along the working strip as a whole to adapt to battery packs of different lengths. The adjustment component meshes with the rack and pinion rail through the toothed block to achieve step-by-step precise movement.

(3) In this utility model, the height is adjusted by raising and lowering the support tube along the sliding hole on the fixed seat to adapt to battery packs of different thicknesses. The probe is adjusted by swinging the arc-shaped sliding hole to ensure good contact with the pole. After adjustment, tightening the bolt can lock the probe angle and the height of the support tube, avoiding poor contact and data error caused by position shift during sampling. (4) The support frame formed by welding the longitudinal beam and the transverse beam in this utility model has strong overall rigidity and can bear the weight of the workbench and each module. It avoids the impact of frame deformation on the detection accuracy during equipment operation. Its support wheels enable convenient movement of the equipment and facilitate the adjustment of the workshop position. The anti-slip rubber pads on the wheels can increase the friction with the ground and ensure that the equipment is stable and does not slip during the detection operation.

[0017] In summary, this utility model provides a battery pack testing machine that is stable, easy to test, and flexible. The device is precisely and stably positioned, highly adaptable, and has a high fault tolerance rate. Its voltage sampling is flexible and reliable, the data is highly accurate, and the testing is efficient and comprehensive. It has a wide range of applications and effectively improves the production efficiency of the equipment. Attached Figure Description

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example 1: like Figures 1 to 9 As shown, a battery pack testing machine includes: The detection device 1 includes a voltage sampling module 2, a detection module 3, and a positioning module 4 on its workbench 101. The voltage sampling module 2 is used to collect voltage from the battery pack 10, the detection module 3 is used to detect the battery pack 10, and the positioning module 4 is used to fix the battery pack 10. The positioning module 4 includes a battery platform 41, a positioning block 42, and a clamping assembly 43. The battery platform 41 is used to place the battery pack 10. The positioning block 42 is located at any corner of the battery platform 41. The clamping assembly 43 is symmetrically arranged with the positioning block 42 and is used to clamp and securely position the battery packs 10 of different specifications.

[0024] The workbench 101 is provided with a plurality of parallel strip holes 1010, which are distributed along the width direction of the workbench 101.

[0025] The clamping assembly 43 has two sets located on both sides of the battery pack 10. The clamping assembly 43 includes a base 431, a rack and pinion rail 432, and a sliding block 433. The base 431 moves in conjunction with the rack and pinion rail 432 through an adjusting assembly 434. The base 431 is slidably disposed within the strip hole 1010 through a reinforcing member 4310. The rack and pinion rail 432 is provided with several sets of toothed grooves 4320. A sliding groove 4312 is provided on a protrusion 4311 on one side of the base 431. The sliding block 433 is connected to the sliding block 433 through a tightening member 4331 passing through the sliding groove 4312.

[0026] A scale 4321 is also provided on the rack and pinion rail 432.

[0027] It should be noted that the scale 4321 is designed to allow for intuitive reading of the movement distance of the base 431, facilitating quick adjustment of the clamping assembly 43 to accommodate battery packs 10 of different specifications.

[0028] The positioning block 42 is L-shaped and abuts against the adjacent two sides of the battery pack 10.

[0029] The adjustment component 434 includes a fixed block 4341, a lead screw 4342, and a toothed block 4343. The fixed block 4341 is fixedly connected to the base 431. The lead screw 4342 is fixedly connected to the fixed block 4341. The end of the lead screw 4342 is rotatably connected to the toothed block 4343. The end of the toothed block 4343 is provided with teeth 4344, which mesh with the tooth groove 4320. A knob 4345 is provided on the top of the toothed block 4343.

[0030] It should be noted that the L-shaped positioning block 42 abuts against the adjacent two sides of the battery pack 10 to form a fixed corner reference. The two sets of parallel clamping components 43 are symmetrically arranged in the direction perpendicular to the reference, which can accurately apply clamping force to the positioning block 42 to prevent the battery pack 10 from shifting, thus solving the problem of no reference and easy misalignment in traditional positioning.

[0031] Secondly, it should be noted that the base 431 is inserted into the strip hole 1010 through the reinforcement 4310, and can move as a whole along the width direction of the workbench 101 to adapt to the battery pack 10 of different lengths. In the adjustment assembly 434, rotating the knob 4345 pushes the tooth block 4343 through the cooperation of the lead screw 4342, and the step-like movement of the base 431 is achieved by the meshing of the teeth 4344 on the tooth block 4343 with the tooth grooves 4320 on the rack rail 432. The sliding block 433 is controlled by the tightening member 4331 to slide within the groove 4312 of the base 431, which can compensate for the size error of the battery pack 10 and ensure that the clamping surfaces are completely fitted.

[0032] Secondly, it should be noted that the two sets of clamping components 43 exert force synchronously, and with the three-point positioning effect of the L-shaped positioning block 42, the battery pack 10 does not shake during the testing process, providing a stable foundation for subsequent sampling and testing.

[0033] The voltage sampling module 2 includes a fixed base 21, a support tube 22, and a probe 23. The fixed base 21 is fixed on the workbench 101. The fixed base 21 is provided with a sliding hole 211. The support tube 22 is slidably connected in the sliding hole 211. The side plate 220 of the support tube 22 is provided with an arc-shaped sliding hole 221. The probe 23 is connected to the side plate 220 by bolts. The bolt at the bottom of the probe 23 passes through the arc-shaped sliding hole 221 and can be adjusted for tightness and swing.

[0034] It should be noted that the voltage sampling module 2 achieves flexible adjustment of the probe 23 position through the sliding hole 211 of the fixing base 21, the arc-shaped sliding hole 221 of the support tube 22, and the bolt connection, adapting to the sampling requirements of different battery packs 10, as follows: Height adjustment mechanism: The support tube 22 is slidably connected to the sliding hole 211 of the fixed base 21, and can be raised and lowered in the vertical direction to adapt to the sampling height of the battery pack 10 with different thicknesses; Angle adjustment mechanism: The probe 23 is connected to the side plate 220 of the support tube 22 by bolts. The bolts are inserted into the arc-shaped sliding hole 221. Loosening the bolts allows the probe 23 to swing and adjust the contact angle between the probe 23 and the terminal post of the battery pack 10, ensuring that the probe 23 contacts the terminal post and avoiding sampling errors caused by poor contact. Position locking mechanism: After adjustment, tighten the bolts to lock the angle of the probe 23 and the height of the support tube 22, ensuring the stability of the probe 23 position during sampling and improving the reliability of the sampling data.

[0035] The detection module 3 includes a probe 31 and a cylinder 32. The cylinder 32 is fixedly connected to the workbench 101 via a connecting seat 321, and the probe 31 is fixedly connected to the output end of the cylinder 32.

[0036] The detection device 1 also includes a temperature sensor 33, which is mounted on a support base 34. The support base 34 includes two sets of parallel vertical rods 341 and a horizontal rod 342 connected to the two sets of vertical rods 341. The temperature sensor 33 can be adjusted and slidably on the horizontal rod 342 by means of a tensioning member 343. The horizontal rod 342 can be raised and lowered on the vertical rods 341 by means of an adjusting member 344.

[0037] It should be noted that the detection module 3, driven by the cylinder 32 and with the support base 34 lifting and sliding, balances detection efficiency and range adaptability. The core cooperation logic is as follows: Power coordination for electrical performance testing: The cylinder 32 is fixed to the worktable 101 via the connecting seat 321. The output end of the cylinder 32 is directly connected to the probe 31, which can quickly drive the probe 31 to move closer to or away from the battery pack 10, thereby automating the testing action and improving testing efficiency. Temperature detection height adaptation: The horizontal bar 342 is raised and lowered on the vertical bar 341 by the adjusting member 344 to adjust the height of the temperature sensor 33 and adapt to the temperature detection point of the battery pack at different heights. Horizontal adaptation for temperature detection: The temperature sensor 33 slides on the crossbar 342 via the tension member 343, and its position can be adjusted in the horizontal direction to cover the temperature detection needs of different areas of the battery pack.

[0038] The bottom of the workbench 101 of the testing device 1 is also provided with a support frame 102. The support frame 102 is a frame structure formed by welding several sets of longitudinal beams and transverse beams. The bottom of the support frame 102 is provided with several sets of sliding support wheels 103. Anti-slip rubber pads 1031 are sleeved on the support wheels 103.

[0039] It should be noted that the support frame 102 has a frame structure formed by welding longitudinal beams and transverse beams, which has high overall rigidity and can bear the weight of the workbench 101 and each module, avoiding detection errors caused by frame deformation during equipment operation. The support wheels 103 enable flexible movement of the equipment and facilitate position adjustment in the workshop. The anti-slip rubber pads 1031 on the wheels can increase the friction with the ground, prevent the equipment from sliding during detection operations, and ensure the overall stability of the equipment during the detection process.

[0040] Working principle: The support frame 102 is formed by welding longitudinal beams and transverse beams. With high rigidity, it supports the workbench and various functional modules, avoiding detection errors caused by frame deformation during equipment operation. By contacting the support wheels 103, the equipment can be flexibly moved to the designated detection position in the workshop. The anti-slip rubber pads 1031 on the support wheels 103 can increase the friction with the ground, prevent the equipment from sliding during detection operations, and ensure overall stability. The battery pack 10 to be tested is placed on the battery platform 41 of the positioning module 4. The L-shaped positioning block 42 abuts against the adjacent two sides of the battery pack 10 to form a fixed corner reference. According to the length specification of the battery pack 10, the reinforcement 4310 is loosened, and the base 431 is pushed to move along the strip hole 1010 in the width direction of the worktable 101 to a suitable position and then fixed again. The knob 4345 of the adjustment component 434 is rotated, and the lead screw 4342 pushes the toothed block 4343 to move. The teeth 4344 on the toothed block 4343 and the rack rail are aligned. The toothed groove 4320 of 432 engages and fixes, enabling the base 431 to move in a step-by-step precision, bringing the clamping component 43 closer to the battery pack. The sliding block 433 slides in the sliding groove 4312 of the base 431 to compensate for the size error of the battery pack 10. After ensuring that the clamping surfaces are fully fitted, the sliding block 433 is fixed by the tightening component 4331. The two sets of parallel clamping components 43 apply clamping force synchronously to the positioning block 42, forming a three-point positioning effect with the L-shaped positioning block 42, which firmly fixes the battery pack 10 and prevents it from shaking during testing.

[0041] Based on the thickness of the battery pack 10, the sliding support tube 22 moves up and down within the sliding hole 211 of the fixed base 21 to adjust the height of the probe 23 to the appropriate position. The bolts connecting the probe 23 are loosened, and the probe is swung through the arc-shaped sliding hole 221 on the side plate 220 of the support tube 22 to adjust its contact angle with the terminal of the battery pack 10 to ensure good contact. After adjustment, the bolts are tightened to lock the angle of the probe 23 and the height of the support tube 22. Subsequently, the probe 23 collects voltage data from the battery pack 10 to ensure stable position during sampling and improve data reliability.

[0042] During electrical performance testing, cylinder 32 is fixed to workbench 101 via connecting seat 321. Its output end drives probe 31 to quickly approach battery pack 10. After completing the electrical performance test, probe 31 is driven away, realizing automated testing and improving efficiency. During temperature testing, the height of horizontal bar 342 on vertical bar 341 is adjusted by adjusting component 344 to match the height of temperature detection point on battery pack 10. The tensioning component 343 is loosened, and the horizontal position of temperature sensor 33 on horizontal bar 342 is slid to cover the temperature detection needs of different areas of battery pack 10. Then, temperature sensor 33 performs temperature detection on battery pack 10.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
