Description

Technical Field

[0001] This utility model relates to the technical field of battery testing, and in particular to a testing device for a battery with multiple leads. Background Technology

[0002] To facilitate further assembly by downstream companies, most batteries retain multiple leads (at least including a live wire and a neutral wire) when shipped. Currently, to ensure battery safety, a comprehensive performance test is conducted on the battery before it leaves the factory by connecting the leads. Because leads have a certain degree of flexibility, especially given their diameter...

[0003] For leads smaller than 1.2mm, during battery production, the multiple leads on the battery are highly likely to become tangled together. Currently, before conducting comprehensive performance testing, it is generally necessary to manually separate each lead and then align each lead with the test point on the testing instrument to ensure that the test point on the instrument can contact the corresponding lead and ensure the accuracy of the testing process. This testing process requires manual separation and straightening of the leads, which wastes a lot of working time, resulting in low battery testing efficiency and indirectly increasing the battery manufacturing cost. Utility Model Content

[0004] This invention provides a testing device for batteries with multiple leads, mainly addressing the technical problem of how to improve the testing efficiency of batteries with multiple leads.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A testing device for a battery with multiple leads includes a frame and a positioning platform, a vision detector, and multiple testing mechanisms connected to the frame. Each testing mechanism includes a connected driver and a test clamp. The test clamp is used to grip the leads on the battery, and the leads gripped by the test clamps in the multiple testing mechanisms are of different colors. The positioning platform is used to position the battery. The vision detector is used to acquire images of the battery located on the positioning platform to obtain position information of the multiple leads of different colors. The vision detector is signal-connected to the drivers in the multiple testing mechanisms to transmit the position information of the leads to the multiple testing mechanisms. Each driver in each testing mechanism drives a corresponding test clamp to grip a corresponding lead based on the position information of the lead to be gripped.

[0007] In one of the technical solutions, the testing equipment further includes a loading mechanism, a unloading mechanism, and a transfer mechanism. The transfer mechanism is connected to the frame and the positioning platform respectively, and is used to drive the positioning platform to move between the first station and the second station. The loading mechanism is connected to the frame and is used to place the battery on the positioning platform located at the first station. The vision detector and multiple testing mechanisms are arranged on one side of the second station. The unloading mechanism is used to move the battery outward from the positioning platform.

[0008] In one of the technical solutions, at least two of the testing mechanisms are arranged vertically on the upper and lower sides of the second workstation.

[0009] In one of the technical solutions, the driver in the testing mechanism includes a transverse movement mechanism, a longitudinal movement mechanism, and a rotation mechanism connected in sequence. The transverse movement mechanism is connected to the frame, and the test clamp is connected to the rotation mechanism.

[0010] In one of the technical solutions, the testing equipment further includes a feeding conveyor and a discharging conveyor connected to the frame respectively. Both the feeding conveyor and the discharging conveyor are used to transport batteries. The loading mechanism is used to move the batteries on the feeding conveyor to the positioning platform located at the first station. The unloading mechanism is used to remove the batteries on the positioning platform located at the first station to the discharging conveyor.

[0011] In one of the technical solutions, the testing equipment further includes a transverse movement device connected to the frame. The loading mechanism and the unloading mechanism are both connected to the transverse movement device. The transverse movement device is used to drive the loading mechanism and the unloading mechanism to move linearly in a first direction. The feeding conveying device, the first station and the discharging conveying device are arranged sequentially along the first direction.

[0012] In one of the technical solutions, both the feeding mechanism and the unloading mechanism include a connected lifting cylinder and an adsorption mechanism. The lifting cylinder is connected to the transverse movement device and is used to drive the adsorption mechanism to move up and down. The adsorption mechanism is used to adsorb batteries.

[0013] In one of the technical solutions, the testing equipment further includes a first positioning mechanism and a second positioning mechanism respectively connected to the positioning platform. The positioning platform is provided with a first reference block and a second reference block. The first reference block is disposed opposite to the first positioning mechanism, and the second reference block is disposed opposite to the second positioning mechanism. The first positioning mechanism is used to push the battery against the first reference block, and the second positioning mechanism is used to push the battery against the second reference block.

[0014] In one technical solution, the testing equipment further includes a sleeve platform and a sleeve device connected to the frame. The sleeve platform is used to receive batteries that have passed the test from the positioning platform. The sleeve device is disposed on one side of the sleeve platform and includes a sleeve main unit, a clamping mechanism, and a cutting mechanism. The clamping mechanism is used to clamp the leads on the battery and drive the leads to align with the sleeve main unit. The sleeve main unit is used to drive the sleeve to automatically fit onto the leads. The cutting mechanism is located between the sleeve main unit and the clamping mechanism and is used to cut the sleeve.

[0015] In one of the technical solutions, the number of the testing mechanisms is three: a test clamp in the first testing mechanism is used to clamp the black lead on the battery; a test clamp in the second testing mechanism is used to clamp the red lead on the battery; and a test clamp in the third testing mechanism is used to clamp the yellow lead on the battery.

[0016] Compared with the prior art, the testing device for batteries with multiple leads provided by this utility model has at least the following beneficial effects:

[0017] During operation, batteries are placed on a positioning platform via manual or automatic feeding. A vision detector then captures images of the batteries on the platform, enabling a backend processor connected to the vision detector to identify the colors of multiple leads (e.g., red live wire and black neutral wire) and calculate the specific position of each lead. The backend processor then transmits the position of each lead to a driver in each testing mechanism. The driver then drives the corresponding test clamp to pick up the corresponding lead, thus completing the battery performance test. This solution eliminates the need for manual sorting and straightening of multiple leads before battery testing, thereby improving testing efficiency and reducing the risk of battery defects caused by manual operation.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Please refer to the following: Figures 1 to 3 This utility model embodiment provides a testing device for a battery with multiple leads. The testing device is used to automatically connect to each lead 101 on the battery 10 to efficiently test the performance of the battery 10. Typically, the leads 101 on the battery 10 are designed with different colors to help users distinguish the function of each lead 101. Typically, the lead 101 is red when used as a live wire, black when used as a neutral wire, and yellow when used as an internal resistance test lead. The testing equipment in this embodiment mainly includes a frame 1 and a positioning platform 2, a vision detector 3, and multiple testing mechanisms 4 that are directly or indirectly connected to the frame 1. Each testing mechanism 4 specifically includes a connected driver 41 and a test clamp 42. The vision detector 3 is signal-connected to the driver 41 in each testing mechanism 4. The driver 41 controls the movement of the test clamp 42 according to the information detected by the vision detector 3. The test clamp 42 is used to clamp the lead wire 101 on the battery 10. Moreover, the lead wire 101 clamped by the test clamp 42 in the multiple testing mechanisms 4 are of different colors. In this embodiment, three testing mechanisms 4 are preferably provided. The test clamp 42 in the first testing mechanism 4 is set to clamp the red lead wire 101, the test clamp 42 in the second testing mechanism 4 is set to clamp the black lead wire 101, and the test clamp 42 in the third testing mechanism 4 is set to clamp the yellow lead wire 101. Thus, the testing equipment in this embodiment can not only perform performance testing on the battery 10 when it is in normal operation, but also test the internal resistance of the battery 10. In other embodiments, if it is only necessary to perform performance testing on the battery 10 when it is in normal working condition, then only two testing mechanisms 4 may be provided in the testing equipment.

[0031] Specifically, in this embodiment, the testing equipment can place the battery 10 on the positioning platform 2 by manual or automatic feeding. The battery 10 is then positioned on the positioning platform 2, and a vision detector 3 acquires images of the battery 10 on the positioning platform 2. This allows the backend processor, connected to the vision detector 3, to identify the colors of the multiple leads 101 (e.g., red live wire and black neutral wire) and calculate the specific position of each lead 101. The backend processor then transmits the specific position of each lead 101 to the driver 41 within each testing mechanism 4. The driver 41 then drives the respective test clamp 42 to pick up the corresponding lead 101, thus completing the performance testing of the battery 10. Using this solution, manual sorting and straightening of the multiple leads 101 is no longer required before testing the battery 10. Therefore, this solution improves the efficiency of battery testing and reduces the risk of defects in the battery 10's appearance due to manual operation.

[0032] Please refer to them again. Figures 1 to 3 The testing equipment in this embodiment also includes a loading mechanism 5 and a unloading mechanism 6, which are directly or indirectly connected to the frame 1. The loading mechanism 5 is used to automatically place the battery 10 on the positioning platform 2, and the unloading mechanism 6 is used to automatically remove the battery 10 that has been tested and is located on the positioning platform 2. This realizes the functions of automatic loading and unloading of the battery 10, which is beneficial to further improve the efficiency of battery 10 performance testing. It should be noted that in this embodiment, the loading mechanism 5 and the unloading mechanism 6 are preferably designed as two separate mechanisms. In other embodiments, if the budget is limited and the requirements for loading and unloading efficiency are not high, the loading mechanism 5 and the unloading mechanism 6 can also be the same mechanism.

[0033] Please refer to them again. Figures 1 to 3The testing equipment in this embodiment also includes a transfer mechanism 7, which is connected to the frame 1 and the positioning platform 2. The transfer mechanism 7 is used to drive the positioning platform 2 to move between the first station 71 and the second station 72. The transfer mechanism 7 is preferably a lead screw linear module. Specifically, the loading mechanism 5 is designed to place the battery 10 on the positioning platform 2 located at the first station 71. The aforementioned vision detector 3 and multiple testing mechanisms 4 are arranged on one side of the second station 72. The reason for this design is that the vision detector 3 and multiple testing mechanisms 4 will occupy a lot of space around the second station 72. Therefore, it is necessary to set up another first station 71 in another location so that the positioning platform 2 can receive the battery 10 from the loading mechanism 5, ensuring that the loading mechanism 5 will not collide with the vision detector 3 or the various testing mechanisms 4 when placing the battery 10 into the positioning platform 2. In this preferred embodiment, after the battery 10 has been tested, the positioning platform 2 returns to the first station 71, and the unloading mechanism 6 unloads the battery 10. In other words, the first station 71 in this embodiment is both the loading station and the unloading station for the battery 10. In other embodiments, the positioning platform 2 may also be moved to a different position than the first station 71 under the drive of the transfer mechanism 7 to allow the unloading mechanism 6 to unload the battery.

[0034] Please see Figure 3 At least two testing mechanisms 4 are vertically arranged on the upper and lower sides of the second station 72. By staggering the testing mechanisms 4 vertically, it is beneficial to prevent the two testing mechanisms 4 from colliding with each other during the action of contacting the corresponding lead wire 101. Preferably, the driver 41 in the testing mechanism 4 specifically includes a transverse movement mechanism 411, a longitudinal movement mechanism 412, and a rotation mechanism 413. The transverse movement mechanism 411 is connected to the frame 1, and the aforementioned test chuck 42 is connected to the rotation mechanism 413. In fact, the transverse movement mechanism 411 is used to drive the longitudinal movement mechanism 412 and the rotation mechanism 413. Mechanism 413 and test chuck 42 move laterally together. The longitudinal movement mechanism 412 drives the rotation mechanism 413 and test chuck 42 to move longitudinally together. The rotation mechanism 413 drives the test chuck 42 to rotate. This design of the driver 41 allows the test chuck 42 to move laterally, longitudinally, and rotate simultaneously, giving it greater freedom in its trajectory. This helps ensure that neither the upper nor lower test chuck 42 collides with other components during contact with the corresponding lead wire 101. The lateral movement mechanism 411 can be a lead screw linear module, a synchronous belt linear module, or a linear motor. The longitudinal movement mechanism 412 is preferably a linear telescopic cylinder, and the rotation mechanism 413 is preferably a rotary cylinder.

[0035] Please refer to the following: Figures 1 to 3The testing equipment in this embodiment also includes a feeding conveyor 8 and a discharging conveyor 9. The feeding conveyor 8 and the discharging conveyor 9 are respectively connected to the frame 1 and are both used to transport the battery 10. The feeding conveyor 8 and the discharging conveyor 9 are preferably belt conveyors. The feeding mechanism 5 actually moves the battery 10 from the feeding conveyor 8 to the positioning platform 2 located at the first station 71. The discharging mechanism 6 actually moves the battery 10 from the positioning platform 2 of the first station 71 to the discharging conveyor 9. Furthermore, the testing equipment in this embodiment also includes a transverse movement device 100, which is connected to the frame 1. The transverse movement device 100 is also connected to the loading mechanism 5 and the unloading mechanism 6. The transverse movement device 100 drives the loading mechanism 5 and the unloading mechanism 6 to move linearly in the first direction X. The feeding conveyor 8, the first station 71, and the discharging conveyor 9 are arranged sequentially along the first direction X. This design facilitates the simultaneous movement of the unloading mechanism 6 from the positioning platform 2 of the first station 71 to the discharging conveyor 9 as the loading mechanism 5 moves from the battery 10 on the feeding conveyor 8 to the positioning platform 2 of the first station 71. In other words, it facilitates the synchronous loading and unloading actions of the loading mechanism 5 and the unloading mechanism 6, thereby improving the feeding efficiency of the battery 10 and thus enhancing the testing efficiency of the battery 10. Preferably, the transverse movement device 100 is a cylinder module.

[0036] Please refer to the following: Figure 1 and Figure 2 With the lateral movement device 100 in place, both the feeding mechanism 5 and the unloading mechanism 6 are specifically designed to include a connected lifting cylinder 51 and an adsorption mechanism 52. The lifting cylinder 51 of the feeding mechanism 5 and the lifting cylinder 51 of the unloading mechanism 6 are connected to the lateral movement device 100. The lifting cylinder 51 is used to drive the adsorption mechanism 52 to move up and down. The adsorption mechanism 52 adsorbs the battery 10 by means of negative pressure. Through the linkage between the lateral movement device 100 and the lifting cylinder 51, the adsorption mechanism 52 with the battery 10 can be moved from the feeding conveying device 8 to the positioning platform 2, or the adsorption mechanism 52 with the battery 10 can be moved from the positioning platform 2 to the unloading conveying device 9, thereby realizing the function of automatic feeding and unloading of the battery 10.

[0037] Please see Figure 2The testing equipment in this embodiment also includes a first positioning mechanism 200 and a second positioning mechanism 300. A first reference block 21 and a second reference block 22 are provided on the positioning platform 2. The first positioning mechanism 200 and the second positioning mechanism 300 are respectively connected to the positioning platform 2. The first reference block 21 is positioned opposite to the first positioning mechanism 200, and the second reference block 22 is positioned opposite to the second positioning mechanism 300. The first positioning mechanism 200 is used to push the battery 10 against the first reference block 21, and the second positioning mechanism 300 is used to push the battery 10 against the second reference block 22. By setting the first positioning mechanism 200 and the second positioning mechanism 300, the battery 10 can be accurately fixed on the positioning platform 2 with the first reference block 21 and the second reference block 22 as references, thereby ensuring that each testing mechanism 4 can subsequently contact its corresponding lead wire 101. After the battery 10 is tested, both the first positioning mechanism 200 and the second positioning mechanism 300 need to be moved away from the battery 10 so that the unloading mechanism 6 can remove the battery 10. The first positioning mechanism 200 and the second positioning mechanism 300 are both preferably propulsion mechanisms powered by cylinders.

[0038] Please see Figure 4 The testing equipment in this embodiment also includes a sleeve platform 400 and a sleeve device 500 connected to the frame 1. The sleeve platform 400 is used to receive the battery 10 that has passed the test from the positioning platform 2. The sleeve device 500 is disposed on one side of the sleeve platform 400. The sleeve device 500 specifically includes a sleeve host 501, a clamping mechanism 502 and a cutting mechanism 503, wherein the cutting mechanism 503 is located between the sleeve host 501 and the clamping mechanism 502. During operation, the clamping mechanism 502 clamps the lead wire 101 on the battery 10 and drives the lead wire 101 to align with the sleeve host 501. Then, the sleeve host 501 drives the sleeve 600 to automatically fit onto the lead wire 101. Then, the cutting mechanism 503 cuts the sleeve 600. The remaining two leads 101 are fitted onto the sleeve 600 in the same way, thus completing the purpose of fitting all three leads 101 onto the sleeve 600 in sequence. Finally, the unloading clamp 700 moves the battery 10 on the sleeve platform 400 to the guide plate 800. The battery 10 that has passed the test and completed the sleeve operation will move down along the guide plate 800 and be collected.

[0039] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
