Abstract
Description
Technical Field
[0001] This invention relates to the field of battery testing technology, and in particular to a lithium-ion battery testing device for smart wearable devices. Background Technology
[0002] In the rapidly developing smart wearable device industry, smart wearable devices have been widely used in people's daily lives and health management. The stable operation of these devices is highly dependent on the performance of their built-in lithium-ion batteries. As the core energy storage unit, the charging and discharging efficiency, cycle life, safety stability, and capacity consistency of lithium-ion batteries directly determine the battery life, reliability, and user experience of smart wearable devices. Therefore, the quality inspection process before the battery leaves the factory or is assembled into the device is particularly critical, and qualified products must be selected through precise testing.
[0003] However, under current technological conditions, the testing process for such lithium-ion batteries still faces a series of significant technical bottlenecks and efficiency challenges. First, many production environments or repair centers still use semi-automated or manually-led testing methods. Operators need to manually place the batteries on the testing station, connect the test probes, start the testing program, and then manually sort and record the results. This method is not only labor-intensive and costly, but also slow, making it difficult to meet the cycle time requirements of large-scale mass production. At the same time, manual operation inevitably introduces subjective errors and consistency fluctuations, affecting the accuracy and reliability of the test results. Although some automated testing equipment has appeared on the market, its design for the connection of automatic battery feeding, precise positioning, continuous flow, and orderly unloading after testing is often not perfect, resulting in the inability to achieve efficient, smooth, and uninterrupted operation of the overall testing process, which limits the further improvement of production capacity.
[0004] Secondly, ensuring a stable and reliable electrical connection between the battery electrodes and the test contacts is the physical basis for obtaining accurate electrical performance data. In traditional testing devices, spring probes or fixed contact plates are often used to achieve the connection. However, during the automatic feeding or removal of the battery from the test position, mechanical vibration, slight positional deviation, or uneven contact pressure may lead to momentary poor contact or increased resistance. In the actual circulation and feeding process of batteries for smart wearable devices, their placement orientation may not be uniform. For example, the orientation of the positive and negative electrodes, or the front of the battery with the markings facing up or down, may all occur. Many existing testing devices lack the ability to adapt to the battery orientation and often require the batteries to be neatly arranged in a fixed orientation for testing. In actual operation, the testing, marking, and sorting processes are often separated. That is, after the battery completes the electrical performance test, it needs to be transferred to another device or another workstation for coding, marking, or sorting and collection, which occupies more space and increases the risk of secondary damage.
[0005] In summary, the development of an intelligent wearable device lithium-ion battery testing apparatus that integrates functions such as automatic battery transfer, precise positioning, reliable electrical contact testing, online result judgment and marking, and automatic unloading is urgently needed to improve testing efficiency, ensure testing quality, reduce labor costs, and achieve intelligent upgrading of production lines. This is precisely the core technical problem that this invention aims to solve and the goal it seeks to achieve. Summary of the Invention
[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution: a lithium-ion battery testing device for a smart wearable device, comprising a transfer mechanism for internal transfer of the lithium battery to be tested and a testing shell, wherein an external support frame is fixedly installed on the testing shell, and a testing mechanism for charging and discharging the lithium battery and an ejection mechanism for pushing the lithium battery from the transfer mechanism into the testing mechanism are provided inside the testing shell. The transfer mechanism includes two track supports fixedly installed inside the detection housing. The track supports are provided with two vertical narrow slots and two curved wide slots. The vertical narrow slots and the curved wide slots are connected. A drive motor is fixedly installed on the detection housing, and a half-tooth gear is fixedly installed on the motor shaft of the drive motor.
[0007] Furthermore, the transfer mechanism also includes two transmission gears rotatably mounted inside the detection housing via a shaft, with an outer gear fixedly mounted on the transmission gears, and a driven wheel rotatably mounted inside the detection housing via a shaft, with a vertical transmission belt wound around the driven wheel and the transmission gears.
[0008] Furthermore, the transfer mechanism also includes a movable rotating frame rotatably mounted on the vertical transmission belt, with limiting blocks fixedly installed on both sides of the movable rotating frame. When the limiting blocks are located in the vertical narrow groove, the two sides of the limiting blocks are in contact with the two sides of the vertical narrow groove.
[0009] Furthermore, the transfer mechanism also includes an inner notch gear fixedly mounted on the half-tooth gear, the inner notch gear meshing with the outer gear.
[0010] Furthermore, the transfer mechanism also includes a battery inlet located on the side of the detection housing, and three limiting baffles are fixedly installed inside the detection housing, with the limiting baffles located next to the battery inlet.
[0011] The drive motor drives the half-tooth gear and the inner missing gear to rotate. The half-tooth gear drives the right outer gear to rotate intermittently, and the inner missing gear drives the outer gear to rotate intermittently. When the half-tooth gear meshes with the right outer gear, the inner missing gear does not mesh with the outer gear. When the inner missing gear meshes with the outer gear, the half-tooth gear does not mesh with the right outer gear. The outer gear drives the transmission gear to rotate, and the transmission gear drives the vertical transmission belt to rotate.
[0012] During use, the lithium battery to be tested is placed into the movable rotating frame located next to the battery inlet. Once the end of the lithium battery contacts the limiting baffle, it indicates that the battery is in place. The vertical transmission belt rotates, driving the movable rotating frame, which in turn moves the lithium battery. When the movable rotating frame and the limiting block move in the vertical narrow slot section, the limiting block and the movable rotating frame cannot rotate because their sides are in contact with the sides of the vertical narrow slot. This ensures that the movable rotating frame and the lithium battery on it remain horizontal during placement and insertion into the testing mechanism. When the movable rotating frame and the limiting block move to the vertical... After the intersection of the straight narrow slot and the curved wide slot, the limiting block enters the curved wide slot. At this time, the limiting block and the moving rotating frame can rotate slightly, which facilitates the limiting block and the moving rotating frame to enter from one vertical narrow slot to another. At this time, the limiting block and the moving rotating frame can only rotate slightly, and the lithium battery will not slide out of the moving rotating frame. When the limiting block and the moving rotating frame reach another vertical narrow slot, the limiting block enters the vertical narrow slot again. The vertical narrow slot limits the limiting block. At this time, the moving rotating frame and the lithium battery return to the horizontal state. Then the moving rotating frame moves with the lithium battery to the side of the inner detection box.
[0013] Furthermore, the ejection mechanism includes a limiting push frame fixedly installed inside the detection housing, an inner ejection block slidably installed inside the limiting push frame, and a chain structure provided on the inner ejection block. The chain mechanism consists of multiple ejection chains that are rotatably installed in relation to each other, and the ejection chain that contacts the inner ejection block is rotatably installed on the inner ejection block.
[0014] Furthermore, the ejection mechanism also includes an ejection sprocket rotatably mounted inside the detection housing, a sprocket gear fixedly mounted on the ejection sprocket, an ejection chain cooperating with the ejection sprocket, a right external gear and a left external gear rotatably mounted inside the detection housing, a right missing gear fixedly mounted on the right external gear, a left missing gear fixedly mounted on the left external gear, the right external gear meshing with the left external gear, when the right missing gear meshes with the sprocket gear, the sprocket gear disengages from the left missing gear, when the left missing gear meshes with the sprocket gear, the right missing gear disengages from the sprocket gear, and the right external gear meshes with the half-tooth gear.
[0015] Each time the inner missing gear meshes with the outer gear, it drives the moving frame to move one position. Then, the half-tooth gear begins to mesh with the right outer gear. The sprocket drives the right outer gear and the right missing gear to rotate. The right outer gear drives the left outer gear and the left missing gear to rotate. The right missing gear drives the sprocket and the ejection sprocket to rotate. The ejection sprocket drives the ejection chain and the inner ejection block to slide along the limit push frame towards the inner detection box. The inner ejection block pushes the lithium battery placed on the moving frame into the inner and outer detection boxes, finally ejecting the lithium battery from the end of the outer detection box. Then, the right missing gear disengages from the sprocket, and the left missing gear begins to mesh with the sprocket. The left missing gear drives the sprocket and the ejection chain... As the sprocket rotates, it drives the ejection chain and inner ejection block to slide away from the inner testing box, causing them to return to their initial positions. Then, the left missing gear disengages from the sprocket gear, and the right missing gear begins to engage with the sprocket gear. At this point, the half-tooth gear disengages from the right outer gear, and the inner missing gear begins to engage with the outer gear. The moving frame then rotates one position, repeating this process. After one rotation of the moving frame, the inner ejection block pushes the lithium battery from the moving frame next to the inner testing box into the inner and outer testing boxes. The tested lithium battery is then ejected, and the inner ejection block returns to its initial position. The moving frame rotates again, and this process repeats.
[0016] Furthermore, the testing mechanism includes an inner testing box fixedly installed on an outer support frame. The inner testing box is fixedly installed with the outer testing shell. An outer testing box is fixedly installed on the inner testing box. Four copper testing plates are arranged inside the inner testing box. Four copper testing plates are arranged inside the outer testing box. An inner standard electric cylinder is fixedly installed below the inner testing box. An inner standard stamp is fixedly installed on the output end of the inner standard electric cylinder. An outer standard electric cylinder is fixedly installed on the outer testing box. An outer standard stamp is fixedly installed on the output end of the outer standard electric cylinder.
[0017] When the inner ejector pushes the lithium battery into the inner testing box, the contacts on the lithium battery come into contact with the copper detection plate inside the inner testing box. At this time, the lithium battery is charged and tested. If the test is qualified, the inner label cylinder extends, so that the inner label stamp adheres to the lower surface of the lithium battery and imprints a qualified mark. If the test is unqualified, the inner label cylinder does not extend. Then the inner ejector pushes the lithium battery into the outer testing box. When the contacts on the lithium battery come into contact with the copper detection plate inside the inner testing box, the lithium battery is discharged and tested. If the test is qualified, the outer label cylinder extends, so that the outer label stamp adheres to the upper surface of the lithium battery and imprints a qualified mark. If the test is unqualified, the outer label cylinder does not extend. Then the inner ejector pushes the lithium battery out from the end of the outer testing box and it falls into the outer collection box. The quality of the lithium battery can be determined by observing whether there are qualified marks on the upper and lower surfaces of the lithium battery.
[0018] The inner and outer label stamps are different colors for easy differentiation. The inner testing box is equipped with a copper testing plate for lithium battery packs, which allows the lithium battery to be tested regardless of whether it is placed face up, face down, or inserted in the correct orientation. At the same time, the copper testing plate has a certain degree of elasticity, which allows it to fit tightly against the contacts of the lithium battery, ensuring reliable testing.
[0019] The beneficial effects of this invention compared with the prior art are: (1) This invention constructs a complete automated detection closed loop through a transfer mechanism, an ejection mechanism, a testing mechanism and a marking mechanism. From the moment the battery is placed in the moving rotating frame through the inlet until the charge and discharge test is completed, the qualified marking is completed and the battery is finally ejected and collected, the entire process does not require manual intervention. The transfer mechanism, through the alternating meshing design of half-tooth gears, inner missing gears and outer gears, combined with the trajectory stand with vertical narrow grooves and curved wide grooves, realizes the intermittent and stable step-by-step conveying of the battery. At the placement position and the detection ejection position, the cooperation of the limiting block and the vertical narrow groove ensures the horizontal and stable posture of the battery. The ejection mechanism, through the alternating drive of the right missing gear and the left missing gear to the sprocket gear, realizes the reciprocating linear motion of the inner ejection block, accurately pushes the battery from the transfer station to the testing station and finally ejects it, realizing the orderly and cyclical cooperation of multiple mechanisms, which is suitable for the rapid detection scenario of large batches of batteries; (2) The inner and outer detection boxes of the testing mechanism set in this invention are both equipped with elastic copper detection plates. When the lithium battery is accurately pushed into the detection box by the inner ejection block, Regardless of its orientation, the elastic copper detection sheet can adaptively and tightly fit the electrode contacts of the battery and provide continuous and stable contact pressure, providing a reliable electrical path for charging and discharging detection. At the same time, during the process of transporting the battery to the detection station, the limiting block in the vertical narrow slot ensures that the battery always maintains a precise horizontal posture when it reaches the push-out position, laying the foundation for the push-out mechanism to smoothly push it into the detection box and ensure accurate alignment of the electrodes and the copper detection sheet, reducing contact problems caused by position deviation; (3) After the charging and discharging detection is completed, the control system drives the inner mark cylinder or the outer mark cylinder to move in real time according to the test results. The qualified battery will be marked with the inner mark stamp on its lower surface, and after the subsequent discharge detection is qualified, it will be marked with the outer mark stamp on its upper surface. The tested and marked batteries are then pushed out to the collection device by the same inner push-out block in continuous motion. The operator or the subsequent automated sorting system only needs to observe whether there is a corresponding two-color qualified mark on the surface of the battery to quickly and intuitively classify and collect them.

Detailed Implementation
[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0033] Example: Reference Figures 1-11 A lithium-ion battery testing device for a smart wearable device includes a transfer mechanism for internal transfer of a lithium battery 4 to be tested and a testing shell 101. An outer support frame 104 is fixedly installed on the testing shell 101. A testing mechanism for charging and discharging tests of the lithium battery 4 and an ejection mechanism for pushing the lithium battery 4 from the transfer mechanism into the testing mechanism are provided inside the testing shell 101. The transfer mechanism includes two track supports 106 fixedly installed inside the detection housing 101. The track supports 106 are provided with two vertical narrow slots 114 and two curved wide slots 115. The vertical narrow slots 114 and the curved wide slots 115 are connected. A drive motor 103 is fixedly installed on the detection housing 101. A half-tooth gear 105 is fixedly installed on the motor shaft of the drive motor 103.
[0034] like Figures 2-7 As shown, the transfer mechanism also includes two transmission gears 109 that are rotatably mounted inside the detection housing 101 via a shaft. An outer gear 110 is fixedly mounted on the transmission gears 109. A drive wheel 116 is rotatably mounted inside the detection housing 101 via a shaft. A vertical transmission belt 111 is wound around the drive wheel 116 and the transmission gears 109.
[0035] like Figures 2-7 As shown, the transfer mechanism also includes a movable rotating frame 108 rotatably mounted on the vertical transmission belt 111. Limiting blocks 112 are fixedly installed on both sides of the movable rotating frame 108. When the limiting blocks 112 are located in the vertical narrow groove 114, the two sides of the limiting blocks 112 are in contact with the two sides of the vertical narrow groove 114.
[0036] like Figures 2-7 As shown, the transfer mechanism also includes an inner missing gear 113 fixedly mounted on the half-tooth gear 105, which meshes with the outer gear 110.
[0037] like Figures 2-7 As shown, the transfer mechanism also includes a battery inlet 102 disposed on the side of the detection housing 101, and three limiting baffles 107 are fixedly installed inside the detection housing 101, with the limiting baffles 107 located next to the battery inlet 102.
[0038] The drive motor 103 drives the half-tooth gear 105 and the inner notched gear 113 to rotate. The half-tooth gear 105 drives the right external gear 206 to rotate intermittently. The inner notched gear 113 drives the outer gear 110 to rotate intermittently. When the half-tooth gear 105 meshes with the right external gear 206, the inner notched gear 113 does not mesh with the outer gear 110. When the inner notched gear 113 meshes with the outer gear 110, the half-tooth gear 105 does not mesh with the right external gear 206. The outer gear 110 drives the transmission gear 109 to rotate. The transmission gear 109 drives the vertical transmission belt 111 to rotate.
[0039] During use, the lithium battery 4 to be tested is placed from the battery inlet 102 onto the movable rotating frame 108 located next to the battery inlet 102. When the end of the lithium battery 4 contacts the limiting baffle 107, it indicates that the lithium battery 4 has been placed in place. The vertical transmission belt 111 rotates, driving the movable rotating frame 108 to move. The movable rotating frame 108 drives the lithium battery 4 to move together. When the movable rotating frame 108 and the limiting block 112 move in the vertical narrow groove 114, the limiting block 112 and the movable rotating frame 108 cannot rotate because their sides are in contact with the sides of the vertical narrow groove 114. This ensures that the movable rotating frame 108 and the lithium battery 4 on it remain horizontal when placed and pushed into the testing mechanism. When the movable rotating frame 108 and the limiting block 112 move to the point where the vertical narrow groove 114 meets the bend... After the intersection of the arc-width groove 115, the limiting block 112 enters the arc-width groove 115. At this time, the limiting block 112 and the moving rotating frame 108 can rotate slightly, so that the limiting block 112 and the moving rotating frame 108 can enter from one vertical narrow groove 114 into another vertical narrow groove 114. At this time, the limiting block 112 and the moving rotating frame 108 can only rotate slightly, and the lithium battery 4 will not slide out of the moving rotating frame 108. When the limiting block 112 and the moving rotating frame 108 reach another vertical narrow groove 114, the limiting block 112 enters the vertical narrow groove 114 again. The vertical narrow groove 114 limits the limiting block 112. At this time, the moving rotating frame 108 and the lithium battery 4 return to the horizontal state. Then the moving rotating frame 108 moves with the lithium battery 4 to the side of the inner detection box 301.
[0040] like Figures 8-10 As shown, the ejection mechanism includes a limiting push frame 201 fixedly installed inside the detection housing 101. An inner ejection block 202 is slidably installed inside the limiting push frame 201. A chain structure is provided on the inner ejection block 202. The chain mechanism consists of multiple ejection chains 204 that are rotatably installed on each other. The ejection chains 204 that are in contact with the inner ejection block 202 are rotatably installed on the inner ejection block 202.
[0041] like Figures 8-10 As shown, the ejection mechanism also includes an ejection sprocket 203 rotatably mounted inside the detection housing 101. A sprocket gear 205 is fixedly mounted on the ejection sprocket 203. An ejection chain 204 engages with the ejection sprocket 203. A right external gear 206 and a left external gear 208 are rotatably mounted inside the detection housing 101. A right missing gear 207 is fixedly mounted on the right external gear 206, and a left missing gear 209 is fixedly mounted on the left external gear 208. The right external gear 206 meshes with the left external gear 208. When the right missing gear 207 meshes with the sprocket gear 205, the sprocket gear 205 disengages from the left missing gear 209. When the left missing gear 209 meshes with the sprocket gear 205, the right missing gear 207 disengages from the sprocket gear 205, and the right external gear 206 meshes with the half-tooth gear 105.
[0042] Each time the inner missing gear 113 engages with the outer gear 110, it drives the movable rotating frame 108 to move one position. Then, the half-tooth gear 105 begins to engage with the right outer gear 206. The sprocket gear 205 drives the right outer gear 206 and the right missing gear 207 to rotate. The right outer gear 206 drives the left outer gear 208 and the left missing gear 209 to rotate. The right missing gear 207 drives the sprocket gear 205 and the ejection sprocket 203 to rotate. The ejection sprocket 203 drives the ejection chain 204 and the inner ejection block 202 to slide along the limiting push frame 201 towards the inner detection box 301. The inner ejection block 202 pushes the lithium battery 4 placed on the movable rotating frame 108 into the inner and outer detection boxes 301, ultimately ejecting the lithium battery 4 from the end of the outer detection box 302. Then, the right missing gear 207 disengages from the sprocket gear 205, and the left missing gear 209 begins to engage with the sprocket gear 205. The left missing gear 209 drives... The moving sprocket 205 and the ejection sprocket 203 rotate, which drives the ejection chain 204 and the inner ejection block 202 to slide away from the inner detection box 301, so that the ejection chain 204 and the inner ejection block 202 return to their initial positions. Then, the left missing gear 209 disengages from the sprocket 205, and the right missing gear 207 begins to mesh with the sprocket 205. At this time, the half-tooth gear 105 disengages from the right outer gear 206, and the inner missing gear 113 begins to mesh with the outer gear 110. At this time, the moving frame 108 continues to rotate one body position, and so on. That is, after the moving frame 108 moves once, the inner ejection block 202 pushes the lithium battery 4 on the moving frame 108 next to the inner detection box 301 into the inner detection box 301 and the outer detection box 302. Then, the lithium battery 4 that has been tested is ejected. Then the inner ejection block 202 returns to its initial position, and the moving frame 108 rotates once more, and so on.
[0043] like Figure 11 As shown, the testing mechanism includes an inner testing box 301 fixedly installed on an outer support frame 104. The inner testing box 301 is fixedly installed with the testing outer shell 101. An outer testing box 302 is fixedly installed on the inner testing box 301. Four copper testing plates 305 are provided inside the inner testing box 301. Four copper testing plates 305 are also provided inside the outer testing box 302. An inner label electric cylinder 303 is fixedly installed below the inner testing box 301. An inner label stamp 304 is fixedly installed on the output end of the inner label electric cylinder 303. An outer label electric cylinder 306 is fixedly installed on the outer testing box 302. An outer label stamp 307 is fixedly installed on the output end of the outer label electric cylinder 306.
[0044] When the inner ejector block 202 pushes the lithium battery 4 into the inner testing box 301, and the contacts on the lithium battery 4 contact the copper testing plate 305 inside the inner testing box 301, a charging test is performed on the lithium battery 4. If the test is successful, the inner label cylinder 303 extends, causing the inner label stamp 304 to adhere to the lower surface of the lithium battery 4 and imprint a success mark. If the test fails, the inner label cylinder 303 does not extend. Subsequently, the inner ejector block 202 pushes the lithium battery 4 into the outer testing box 302. When the contacts on the lithium battery 4 contact the copper testing plate 305 inside the inner testing box 301, a charging test is performed on the lithium battery 4. After the copper detection plate 305 inside the test chamber 301 makes contact, the lithium battery 4 is discharged for testing. If the test is qualified, the outer label cylinder 306 extends, so that the outer label stamp 307 adheres to the upper surface of the lithium battery 4 and imprints a qualified mark. If the test is unqualified, the outer label cylinder 306 does not extend, and then the inner push-out block 202 pushes the lithium battery 4 out from the end of the outer test chamber 302 and into the outer collection box. The lithium battery 4 can be judged as qualified by observing whether there are qualified marks on the upper and lower surfaces of the lithium battery 4.
[0045] The inner label stamp 304 and the outer label stamp 307 are different colors for easy differentiation. The inner testing box 301 is equipped with four sets of copper testing plates 305 for lithium batteries, which allows the lithium batteries 4 to be tested regardless of whether they are placed face up, face down, or inserted in the correct orientation. At the same time, the copper testing plates 305 have a certain degree of elasticity, which allows them to fit tightly against the contacts of the lithium batteries 4, ensuring reliable testing.
[0046] The working principle of the lithium-ion battery detection device for a smart wearable device disclosed in this invention is as follows: the drive motor 103 drives the half-tooth gear 105 and the inner missing gear 113 to rotate. The half-tooth gear 105 drives the right external gear 206 to rotate intermittently, and the inner missing gear 113 drives the outer gear 110 to rotate intermittently. When the half-tooth gear 105 meshes with the right external gear 206, the inner missing gear 113 does not mesh with the outer gear 110. When the inner missing gear 113 meshes with the outer gear 110, the half-tooth gear 105 does not mesh with the right external gear 206. The outer gear 110 drives the transmission gear 109 to rotate, and the transmission gear 109 drives the vertical transmission belt 111 to rotate. During use, the lithium battery 4 to be tested is placed from the battery inlet 102 onto the movable rotating frame 108 located next to the battery inlet 102. When the end of the lithium battery 4 contacts the limiting baffle 107, it indicates that the lithium battery 4 has been placed in place. The vertical transmission belt 111 rotates, driving the movable rotating frame 108 to move. The movable rotating frame 108 drives the lithium battery 4 to move together. When the movable rotating frame 108 and the limiting block 112 move in the vertical narrow groove 114, the limiting block 112 and the movable rotating frame 108 cannot rotate because their sides are in contact with the sides of the vertical narrow groove 114. This ensures that the movable rotating frame 108 and the lithium battery 4 on it remain horizontal when placed and pushed into the testing mechanism. When the movable rotating frame 108 and the limiting block 112 move to the point where the vertical narrow groove 114 meets the bend... After the intersection of the arc-width groove 115, the limiting block 112 enters the arc-width groove 115. At this time, the limiting block 112 and the moving rotating frame 108 can rotate slightly, so that the limiting block 112 and the moving rotating frame 108 can enter from one vertical narrow groove 114 into another vertical narrow groove 114. At this time, the limiting block 112 and the moving rotating frame 108 can only rotate slightly, and the lithium battery 4 will not slide out of the moving rotating frame 108. When the limiting block 112 and the moving rotating frame 108 reach another vertical narrow groove 114, the limiting block 112 enters the vertical narrow groove 114 again. The vertical narrow groove 114 limits the limiting block 112. At this time, the moving rotating frame 108 and the lithium battery 4 return to the horizontal state. Then the moving rotating frame 108 moves with the lithium battery 4 to the side of the inner detection box 301.
[0047] Each time the inner missing gear 113 engages with the outer gear 110, it drives the movable rotating frame 108 to move one position. Then, the half-tooth gear 105 begins to engage with the right outer gear 206. The sprocket gear 205 drives the right outer gear 206 and the right missing gear 207 to rotate. The right outer gear 206 drives the left outer gear 208 and the left missing gear 209 to rotate. The right missing gear 207 drives the sprocket gear 205 and the ejection sprocket 203 to rotate. The ejection sprocket 203 drives the ejection chain 204 and the inner ejection block 202 to slide along the limiting push frame 201 towards the inner detection box 301. The inner ejection block 202 pushes the lithium battery 4 placed on the movable rotating frame 108 into the inner and outer detection boxes 301, ultimately ejecting the lithium battery 4 from the end of the outer detection box 302. Then, the right missing gear 207 disengages from the sprocket gear 205, and the left missing gear 209 begins to engage with the sprocket gear 205. The left missing gear 209 drives... The moving sprocket 205 and the ejection sprocket 203 rotate, which drives the ejection chain 204 and the inner ejection block 202 to slide away from the inner detection box 301, so that the ejection chain 204 and the inner ejection block 202 return to their initial positions. Then, the left missing gear 209 disengages from the sprocket 205, and the right missing gear 207 begins to mesh with the sprocket 205. At this time, the half-tooth gear 105 disengages from the right outer gear 206, and the inner missing gear 113 begins to mesh with the outer gear 110. At this time, the moving frame 108 continues to rotate one body position, and so on. That is, after the moving frame 108 moves once, the inner ejection block 202 pushes the lithium battery 4 on the moving frame 108 next to the inner detection box 301 into the inner detection box 301 and the outer detection box 302. Then, the lithium battery 4 that has been tested is ejected. Then the inner ejection block 202 returns to its initial position, and the moving frame 108 rotates once more, and so on.
[0048] When the inner ejector block 202 pushes the lithium battery 4 into the inner testing box 301, and the contacts on the lithium battery 4 contact the copper testing plate 305 inside the inner testing box 301, a charging test is performed on the lithium battery 4. If the test is successful, the inner label cylinder 303 extends, causing the inner label stamp 304 to adhere to the lower surface of the lithium battery 4 and imprint a success mark. If the test fails, the inner label cylinder 303 does not extend. Subsequently, the inner ejector block 202 pushes the lithium battery 4 into the outer testing box 302. When the contacts on the lithium battery 4 contact the copper testing plate 305 inside the inner testing box 301, a charging test is performed on the lithium battery 4. After the copper detection plate 305 inside the testing chamber 301 makes contact, the lithium battery 4 is discharged for testing. If the test is successful, the outer label cylinder 306 extends, causing the outer label stamp 307 to adhere to the upper surface of the lithium battery 4, imprinting a pass mark. If the test fails, the outer label cylinder 306 does not extend, and then the inner ejection block 202 pushes the lithium battery 4 out from the end of the outer testing chamber 302, where it falls into the outer collection box. The pass or fail status of the lithium battery 4 can be determined by observing whether there are pass marks on the upper and lower surfaces of the lithium battery 4. The inner label stamp 304 and the outer label stamp 307 are different colors for easy differentiation. The inner testing chamber 301 is equipped with four sets of copper detection plates 305 for the lithium battery 4, allowing for testing regardless of whether the lithium battery 4 is placed face up, face down, or inserted in any direction. The copper detection plates 305 also have a certain degree of elasticity, ensuring they adhere tightly to the contacts of the lithium battery 4, guaranteeing reliable testing.
