[0002] During the battery production process, it is often necessary to test the produced batteries to ensure that they are in optimal condition in order to improve the product qualification rate. When testing lithium batteries, they need to be placed in a tray in sequence, and then the tray is arranged to allow multiple batteries to be tested and loaded at the same time, which also improves the stability of the batteries during the testing process.

[0003] There is an OCV testing machine used to detect whether manufactured batteries are qualified. However, the OCV testing machine only has testing functions and cannot automatically remove unqualified batteries from the battery tray after completing the test in one device, thus resulting in low battery production efficiency.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1 to 10 This utility model proposes an integrated battery testing and selection machine.

[0033] The battery testing and selection integrated machine includes a frame 100, a probe module 300, a robotic arm module 400, and multiple conveyor belt modules 500. A roller assembly 110 is mounted on the frame 100 for placing battery trays. Two X-axis guide rails 200 are mounted on the frame 100, and an X-axis slide rail 210 is slidably connected between the two X-axis guide rails 200. The probe module 300 includes a fixed base 310 and a probe assembly 320. The fixed base 310 is mounted on the X-axis slide rail 210, and the probe assembly 320 is vertically mounted on the fixed base 310. The robotic arm module 400 includes a Y-axis slide 410 and a robotic arm assembly 420. The Y-axis slide 410 is slidably mounted on the X-axis slide rail 210, and the robotic arm assembly 420 is vertically mounted on the Y-axis slide 410. The robotic arm assembly 420 can select batteries 112 from the battery tray and place them into the conveyor belt modules 500 for transport.

[0034] Specifically, the roller assembly 110 can transport battery trays in and out. During operation, battery trays flow onto the roller assembly 110 from the production line. The X-axis slide rail 210 slides, causing the probe module 300 and the robotic arm module 400 to move in the X-axis direction. When the probe assembly 320 reaches above the battery tray, the X-axis slide rail 210 stops moving, and the probe assembly 320 descends, causing the test probes in the probe assembly 320 to contact and press against the tabs of each battery 112 in the battery tray for testing. After testing, the probe assembly 320 rises, and the movement of the X-axis slide rail 210, in conjunction with the movement of the Y-axis slide block 410, drives the robotic arm assembly 420 to adjust its position in both the X and Y axes, moving it to the desired testing location. Above the battery 112, the robotic arm assembly 420 descends to grab the defective battery 112 and places it onto the conveyor belt module 500 via the X-axis slide rail 210 and Y-axis slide block 410. Whenever a slot in the conveyor belt module 500 is filled with defective batteries 112, the module moves them to the next slot until all defective batteries 112 in the battery tray are selected. Then, the roller assembly 110 transports the battery tray containing the qualified batteries 112 out, allowing workers to remove the defective batteries. This design integrates battery testing and selection functions into a single device, enabling the integrated battery testing and selection machine to immediately select defective batteries after testing. Compared to traditional OCV testing machines with only one testing function, this integrated battery testing and selection machine significantly improves battery production efficiency.

[0035] Please see Figures 2 to 5 Furthermore, a first Z-axis guide rail 423 is mounted on the Y-axis slide 410. The robotic arm assembly 420 includes a first Z-axis slide 421 and a robotic arm 422. The first Z-axis slide 421 is slidably connected to the first Z-axis guide rail 423, and the robotic arm 422 is mounted on the first Z-axis slide 421. Specifically, when the Y-axis slide 410 slides on the X-axis slide rail 210, it can drive the first Z-axis guide rail 423, the first Z-axis slide 421, and the robotic arm 422 to move. The movement of the robotic arm 422 on the X, Y, and Z axes can be realized through the first Z-axis slide 421, the Y-axis slide 410, and the X-axis slide rail 210.

[0036] Please see Figures 2 to 5Furthermore, a second Z-axis guide rail 330 is mounted on the fixed base 310, and a second Z-axis slide block 340 is mounted on the probe assembly 320. The second Z-axis slide block 340 is slidably mounted on the second Z-axis guide rail 330. In this way, the X-axis slide rail 210 and the second Z-axis guide rail 330 can move the probe assembly 320 in the X-axis and Z-axis directions, ensuring that the probe assembly 320 can be accurately pressed against the battery 112 tab of the battery tray.

[0037] Please see Figure 1 and Figure 6 Furthermore, the conveyor belt module 500 includes a conveyor belt 510, a servo motor 520, and a support base 530. The servo motor 520 is mounted on the support base 530, which also houses a drive shaft 540 and a transmission shaft 550. The conveyor belt 510 surrounds the drive shaft 540 and the transmission shaft 550. The servo motor 520 drives the drive shaft 540 via a synchronous belt assembly to drive the conveyor belt 510. Specifically, the servo motor 520 drives the drive shaft 540 to rotate via the synchronous belt assembly, which in turn drives the conveyor belt 510 to rotate, thus enabling the conveyor belt 510 to transport defective batteries 112. That is, whenever the robotic arm 422 picks up a defective battery 112 and places it on the conveyor belt 510, the servo motor 520 operates to transport the defective battery 112 one gear.

[0038] Please see Figure 1 and Figure 6 Furthermore, the synchronous belt assembly includes a synchronous belt 560, a first synchronous pulley 570, and a second synchronous pulley 580. A servo motor 520 drives and connects to the first synchronous pulley 570. The synchronous belt 560 surrounds the outer periphery of the first synchronous pulley 570 and the second synchronous pulley 580. A drive shaft 540 is connected to the second synchronous pulley 580. Specifically, the servo motor 520 drives the first synchronous pulley 570 to rotate, and the synchronous belt 560 and the second synchronous pulley 580 operate synchronously. The second synchronous pulley 580 drives the drive shaft 540 to rotate, thereby driving the conveyor belt 510 to operate and the driven pulley to rotate.

[0039] Please see Figure 1 and Figure 6 Furthermore, the bottom of the support base 530 is provided with a support foot 590, which is used to support the ground. In this way, the support foot 590 can support the ground, allowing the conveyor belt module 500 to extend outside the frame 100, preventing obstruction by foreign objects when removing the defective battery 112.

[0040] Please see Figure 1 and Figure 9Furthermore, a calibration platform 650 is mounted on the rack 100. Multiple calibration components 600 are arranged in an array on the calibration platform 650. Each calibration component 600 includes a positive copper block 610, a negative copper block 620, a standard resistor 630, and a bakelite block 640. The bakelite block 640 is mounted on the rack 100, and the standard resistor 630, positive copper block 610, and negative copper block 620 are mounted on the bakelite block 640. The positive copper block 610 and negative copper block 620 are connected to the standard resistor 630, and are used to contact the conductive probe assembly 320. It is understood that the bakelite block 640 can be directly embedded in the calibration platform 650. After prolonged testing, the probes of the probe assembly 320 may experience inaccurate testing accuracy. By setting a calibration component 600 on the battery testing and selection machine, after a certain period of time, the positive and negative probes of each group of test probes in the probe component 320 contact the positive copper block 610 and the negative copper block 620 respectively, so that the test probe can detect the test value of the standard resistance 630 and compare the test value with the standard value, thereby calibrating the test probe.

[0041] Please see Figure 1 and Figure 10 Furthermore, the battery testing and selection integrated machine also includes a blocking assembly 700, which includes a fixed base 710, an adjusting block 720, and a blocking block 730. The blocking block 730 is mounted on the fixed base 710, which is mounted on the frame 100. The adjusting block 720 has an adjusting hole 721, which allows a bolt to pass through and press against the blocking block 730, thus making the position of the blocking block 730 adjustable. Specifically, the blocking block 730 can block the battery tray, and the position of the blocking block 730 can be adjusted by the adjusting block 720. The position of the bolt can be adjusted by rotating the bolt in the adjusting hole 721, thereby adjusting the position of the blocking block 730, and consequently the position of the battery tray, ensuring the accuracy of the test probes of the probe assembly 320 pressing against the battery 112 tabs.

[0042] Please see Figures 7 to 8 Furthermore, the battery testing and sorting integrated machine also includes a lifting mechanism 800, which includes a fixed plate 810, a lifting reference plate 820, and a lifting cylinder 830. The fixed plate 810 is fixedly installed on the frame 100, and the lifting cylinder 830 is installed on the fixed plate 810. The telescopic rod of the lifting cylinder 830 drives the lifting reference plate 820. Specifically, after the battery tray is blocked in place by the blocking block 730, the lifting cylinder 830 operates to lift the lifting reference plate 820. At this time, the probe assembly 320 begins to operate and contact and press against the battery 112 on the battery tray. After the test is completed, the robot arm 422 selects the battery 112 and places it on the conveyor belt 510.

[0043] Please see Figure 1 , Figure 7 as well as Figure 8 Furthermore, guide rail support seats 840 are provided at the bottom corners of the lifting reference plate 820, and sliding guide rails 850 are provided on the guide rail support seats 840. A positioning slider 860 is fixed on the fixed plate 810, and the sliding guide rail 850 is slidably connected to the positioning slider 860. In this way, when the lifting cylinder 830 drives the lifting reference plate 820 to rise and fall, the lifting reference plate 820 can slide relative to the fixed plate 810. At the same time, due to the structural limitations of the positioning slider 860 and the sliding guide rail 850, the sliding guide rail 850 can be prevented from deviating, ensuring the stability of the movement of the sliding guide rail 850.

[0044] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. All equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
