Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery technology, and specifically to a cylindrical battery testing device. Background Technology

[0002] For the battery manufacturing process, battery quality inspection is of paramount importance. In the automated production process of batteries, it is inevitable that a small number of batteries will have defects in appearance, such as dents, scratches, bulges, electrolyte contamination, dirt, etc. There are even cases of missing parts being assembled, which not only affects the appearance but also has a significant impact on the safety of battery production and use. Before battery assembly, the appearance of the battery must be inspected to ensure the battery appearance qualification rate.

[0003] Currently, in cylindrical battery testing equipment, a clamping mechanism is typically used to remove cylindrical batteries from the holder. The clamping mechanism usually consists of two clamping plates that fit together at the top of the battery. The clamping mechanism is then rotated 90° from a vertical position to a horizontal position. However, after the cylindrical battery is rotated, the clamping mechanism is essentially clamped to one side of the battery. Due to the weight of the cylindrical battery, if the clamping force is too weak, the cylindrical battery is prone to tilting downwards relative to the clamping mechanism and eventually falling. If the clamping force is too strong, it can easily affect the appearance and shape of the cylindrical battery. Utility Model Content

[0024] Please see Figures 1 to 4 This invention provides a cylindrical battery testing device according to one embodiment, comprising: The feeding device 10, the detection device 20, and the unloading device 30 are arranged in sequence. The feeding device 10 includes a material conveying mechanism 110, a transfer mechanism 120, and a feeding robot assembly 130. The transfer mechanism 120 includes a transfer platform 121, a guide plate 122, and a plurality of transfer positioning slots 123. The transfer positioning slots 123 are arranged on the transfer platform 121 along a preset direction. The guide plate 122 is disposed on the transfer platform 121 and is located on the side of the transfer positioning slots 123 facing the material conveying mechanism 110. The guide plate 122 gradually extends upward in the direction close to the transfer positioning slots 123. The loading robot assembly 130 includes a loading translation drive module 131, a loading mounting frame 132, and multiple magnetic suction components 133. The loading translation drive module 131 is driven to connect with the loading mounting frame 132. The loading mounting frame 132 moves back and forth between the material conveying mechanism 110 and the transfer positioning groove 123 under the drive of the loading translation drive module 131. The multiple magnetic suction components 133 are arranged sequentially on the loading mounting frame 132 along a preset direction. When the loading robot assembly 130 attracts the cylindrical battery on the material conveying mechanism 110 through the magnetic suction component 133 and drives the cylindrical battery toward the transfer positioning groove 123, the cylindrical battery abuts against the guide plate 122 and flips under the guidance of the guide plate 122. After the cylindrical battery enters the transfer positioning groove 123, the magnetic suction component 133 disengages from the cylindrical battery. The testing device 20 is used to inspect the appearance of the cylindrical battery and determine whether the appearance of the cylindrical battery is qualified.

[0025] The feeding device 30 is used to remove the cylindrical battery from the detection device 20 and then move it to a suitable position.

[0026] The working principle of the feeding device 10 according to one embodiment of the present invention will be explained below: The feeding conveyor 110 delivers multiple trays carrying batteries to their positions. Then, the loading robot assembly 130 moves to the feeding conveyor 110. Next, the loading robot assembly 130 uses the magnetic suction component 133 to attract the top of the cylindrical batteries on the feeding conveyor 110, thereby clamping and suspending the batteries below the magnetic suction component 133. Then, as the loading translation drive module 131 continues to drive the loading mounting frame 132 toward the transfer positioning slot 123, the bottom of the cylindrical battery will abut against the bottom of the guide plate 122. As the loading mounting frame 132 and the magnetic suction component 133 continue to move, the bottom of the battery will gradually flip upward under the guidance of the guide plate 122. Then, after the cylindrical battery enters the transfer positioning slot 123, the magnetic suction component 133 detaches from the cylindrical battery. At this time, the cylindrical battery will be placed horizontally in the transfer positioning slot 123, realizing the flipping of the cylindrical battery.

[0027] The specific structure of the loading translation drive module 131 can be designed according to actual needs. For example, the loading translation drive module 131 can adopt a two-axis translation drive module or a three-axis translation drive module, etc., to realize the multiple axial translation of the loading mounting frame 132. The principle and structure of the multi-axis translation drive module are well known to those skilled in the art and will not be described in detail here.

[0028] Please see Figure 5 and Figure 6 The separation method of the cylindrical battery can be designed according to actual needs. For example, a limiting structure can be set on the side of the transfer positioning groove 123 away from the guide plate 122. After the cylindrical battery enters the transfer positioning groove 123, the cylindrical battery abuts against the limiting structure and cannot continue to move, while the loading mounting frame 132 and the magnetic suction component 133 can continue to move, thus realizing the separation of the cylindrical battery and the magnetic suction component 133. Alternatively, the magnetic suction component 133 can also be an electromagnet. By starting or stopping the magnetic suction function of the electromagnet, the adsorption and separation with the cylindrical battery can be realized. In this embodiment, the loading mounting frame 132 is provided with a stop portion 1321, and the stop portion 1321 is provided with multiple through holes 1322. The loading robot assembly 130 also includes a movable frame 134 and a separation drive module 135. The movable frame 134 is vertically and vertically mounted on the loading mounting frame 132 and located above the stop portion 1321. The separation drive module 135 is drivenly connected to the movable frame 134. The magnetic suction member 133 is mounted on the movable frame 134. The separation drive module 135 drives the movable frame 134 to rise and fall, thereby driving the magnetic suction member 133 to move from the through hole 1322 to below the stop portion 1321 and to move the magnetic suction member 133 into the through hole 1322 or into the through hole 1322. Above the stop portion 1321; the separation drive module 135 drives the movable frame 134 to descend, causing the magnetic suction member 133 to move to extend from the through hole 1322 to below the stop portion 1321. At this time, the magnetic suction member 133 can magnetically engage with the top of the cylindrical battery. When it is necessary to separate the magnetic suction member 133 from the cylindrical battery, the separation drive module 135 drives the movable frame 134 to rise, and the magnetic suction member 133 moves into the through hole 1322 or above the stop portion 1321. During the rising process of the magnetic suction member 133, the cylindrical battery will abut against the bottom of the stop portion 1321 and cannot continue to rise. As the magnetic suction member 133 continues to rise, it can separate the magnetic suction member 133 from the cylindrical battery.

[0029] The specific structure of the separate drive module 135 can be selected according to actual needs. For example, the separate drive module 135 can be a lead screw drive module, a rotary motor 312 translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0030] To facilitate stable installation of the magnetic component 133, in some optional embodiments, the bottom of the movable frame 134 is provided with a protruding magnetic mounting portion 1341, and a magnetic mounting groove 1342 is provided on the magnetic mounting portion 1341. The magnetic component 133 is assembled into the magnetic mounting groove 1342, with a portion of the magnetic component 133 extending out of the magnetic mounting groove 1342. The magnetic mounting portion 1341 can slide with the through hole 1322, thereby improving the stability of the lifting and lowering of the magnetic component 133.

[0031] In some alternative embodiments, the magnetic suction component 133 is rotatably mounted on the loading mounting frame 132. When the cylindrical battery is rotated by the guide plate, the magnetic suction component 133 can rotate together with the cylindrical battery, thereby enabling the magnetic suction component 133 to stably maintain adsorption with the cylindrical battery.

[0032] In some alternative embodiments, the magnetic accumulator 133 is circular in cross-section parallel to the vertical direction. The cylindrical battery is adsorbed on the outer peripheral curved surface of the magnetic accumulator 133. When the cylindrical battery is flipped, it can also move along the outer peripheral curved surface of the magnetic accumulator 133 to maintain stable adsorption with the magnetic accumulator 133, thereby avoiding the situation where the magnetic accumulator 133 cannot rotate normally.

[0033] Please see Figure 7 The specific structure of the material conveying mechanism 110 can be designed according to actual needs. For example, in some optional embodiments, the material conveying mechanism 110 includes a material conveyor belt 111, a first material positioning plate 112, a second material positioning plate 113, a positioning drive module 114, and two blocking modules 115. The material conveyor belt 111 is located on one side of the transfer station 121. The loading mounting frame 132 is driven by the loading translation drive module 131 and moves between the material conveyor belt 111 and the transfer positioning groove 125. The two blocking modules 115 are arranged sequentially along the conveying direction of the incoming material conveyor belt 111. The blocking modules 115 are used to block the movement of the battery on the incoming material conveyor belt 111. The first incoming material positioning plate 112 and the second incoming material positioning plate 113 are respectively set on both sides of the incoming material conveyor belt 111 and located between the two blocking modules 115. The first incoming material positioning plate 112 has a plurality of incoming material positioning grooves 1121 arranged sequentially in a preset direction on the side facing the second incoming material positioning plate 113.

[0034] The feeding conveyor belt 111 transports the trays carrying cylindrical batteries until they contact one of the blocking modules 115. After the number of trays between the two blocking modules 115 meets the requirements, the other blocking module 115 moves to the feeding conveyor belt 111 to stop the trays from moving further. Then, the positioning drive module 114 drives the first feeding positioning plate 112 to move toward the second feeding positioning plate 113. The feeding positioning groove 1121 is positioned and engaged with the corresponding tray to achieve positioning of the tray and maintain a suitable distance between adjacent trays. Then, the loading robot assembly 130 can adsorb and move the cylindrical batteries away from the trays. Subsequently, the first feeding positioning plate 112 moves away from the second feeding positioning plate 113, and the blocking module 115 leaves the feeding conveyor belt 111, so that the empty trays are transported away.

[0035] The specific structure of the positioning drive module 114 can be selected according to actual needs. For example, the positioning drive module 114 can be a lead screw drive module, a rotary motor 312 translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0036] The specific structure of the blocking module 115 can be selected according to the actual needs. For example, the blocking module 115 includes a blocking block and a telescopic cylinder. The telescopic cylinder drives the blocking block to move onto or off the material conveyor belt 111, thereby blocking the cup holder or releasing the restriction on the cup holder.

[0037] In some optional embodiments, the loading device 10 of the cylindrical battery testing equipment further includes a transfer robot assembly 140; the transfer mechanism 120 further includes a first transfer translation drive module 124, which is drivenly connected to the transfer platform 121. The transfer robot assembly 140 and the loading robot assembly 130 are arranged sequentially along the moving direction of the transfer platform 121. The transfer robot assembly 140 is used to clamp and move the cylindrical batteries in the transfer positioning slot 123. The transfer robot assembly 140 transports the cylindrical batteries out of the transfer positioning slot 123 of the transfer platform 121 and then transports them to the testing device 20. The first transfer translation drive module 124 drives the transfer platform 121 to move to one side of the transfer robot assembly 140 and the loading robot assembly 130, thereby transporting the cylindrical batteries from the side of the loading robot assembly 130 to the side of the transfer robot assembly 140.

[0038] The specific structure of the first transfer translation drive module 124 can be selected according to actual needs. For example, the first transfer translation drive module 124 can adopt a screw drive module, a rotary motor 312 translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0039] Please see Figures 8 to 10 The specific structure of the transfer robot assembly 140 can be designed according to actual needs. For example, in some optional embodiments, the transfer robot assembly 140 includes a second transfer translation drive 141, a transfer mounting frame 142, a spacing adjustment mechanism 143, and multiple transfer clamping modules 144. The second transfer translation drive is driven and connected to the transfer mounting frame 142. The multiple transfer clamping modules 144 are movably mounted on the transfer mounting frame 142. The spacing adjustment mechanism 143 is driven and connected to the multiple transfer clamping modules 144 to drive the multiple transfer clamping modules 144 to move. The transfer clamping modules 144 are used to clamp cylindrical batteries, and the spacing adjustment mechanism 143 is used to adjust the spacing between adjacent cylindrical batteries to meet the requirements of subsequent processes.

[0040] The specific structure of the second transfer translation drive 141 can be designed according to actual needs. For example, the second transfer translation drive 141 can adopt a two-axis translation drive module or a three-axis translation drive module, etc., to realize the multiple axial translation of the loading mounting frame 132. The principle and structure of the multi-axis translation drive module are well known to those skilled in the art and will not be described in detail here.

[0041] The specific structure of the spacing adjustment mechanism 143 can be designed according to actual needs. For example, in some optional embodiments, the spacing adjustment mechanism 143 includes multiple sliding blocks 1431, multiple scissor arms 1432, and an adjustment drive module 1433. The sliding blocks 1431 are slidably mounted on the transfer mounting frame 142, and the scissor arms 1432 are correspondingly mounted on the sliding blocks 1431. The scissor arms 1432 include a first fork arm 14321 and a second fork arm 14322. The first fork arm 14321 and the second fork arm 14322... The two forks 14322 are rotatably mounted on the sliding block 1431 and are arranged to cross each other. The first fork 14321 on the sliding block 1431 is rotatably engaged with the second fork 14322 on the adjacent sliding block 1431, and the second fork 14322 on the sliding block 1431 is rotatably engaged with the first fork 14321 on the adjacent sliding block 1431. The adjustment drive module 1433 is drivenly connected to the sliding block 1431, and the transfer clamping module 144 is correspondingly mounted on the sliding block 1431. Adjacent scissor arms 1432 cooperate to form a parallelogram structure. When the adjustment drive module 1433 drives the sliding block 1431 to move, the multiple scissor arms 1432 cooperate to drive the multiple sliding blocks 1431 to move the same distance together, so that the multiple sliding blocks 1431 maintain the same distance, and thus the various transfer clamping modules 144 maintain the same distance. Therefore, the adjustment drive module 1433 can adjust the distance between the various clamping modules by driving the movement of the sliding blocks 1431.

[0042] The specific structure of the adjustment drive module 1433 can be designed according to actual needs. For example, the adjustment drive module 1433 can be a lead screw drive module, a rotary motor 312 translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0043] Please see Figure 11 and Figure 12 This invention provides a detection device 20 for a cylindrical battery testing equipment, comprising: The battery handling assembly 210 includes a handling drive module 211, a loading handling module 212, a unloading handling module 213, and multiple intermediate handling modules 214. The handling drive module 211 is drivenly connected to the loading handling module 212, the unloading handling module 213, and the multiple intermediate handling modules 214. The loading handling module 212, the multiple intermediate handling modules 214, and the unloading handling module 213 are arranged sequentially along the driving direction of the handling drive module 211. The battery handling assembly 210 is arranged on one side of the transfer mechanism 120, and the transfer robot assembly 140 is located between the battery handling assembly 210 and the transfer mechanism 120. Multiple battery carrier modules 220 are arranged sequentially along the driving direction of the transport drive module 211. In some optional embodiments, to classify cylindrical batteries that are found to be visually defective, so as to facilitate the separate transportation of defective and qualified cylindrical batteries, the battery carrier module 220 includes an NG carrier module 222 and multiple detection carrier modules 221. The multiple detection carrier modules 221 and NG carrier modules 222 are arranged sequentially along the driving direction of the transport drive module 211. Multiple appearance detection components 230 are correspondingly arranged at the multiple detection carrier modules 221. When a cylindrical battery is placed on the NG carrier module 222, the corresponding defective cylindrical battery on the NG carrier module 222 can be removed manually or by a robotic arm.

[0044] The transport drive module 211 can drive the loading transport module 212, the unloading transport module 213 and the multiple intermediate transport modules 214 to move together to the first position and the second position. When the loading transport module 212, the unloading transport module 213 and the multiple intermediate transport modules 214 are in the first position, the loading transport module 212 and the multiple intermediate transport modules 214 are respectively located at the multiple battery carrying modules 220. When the loading transport module 212, the unloading transport module 213 and the multiple intermediate transport modules 214 are in the first position, the multiple intermediate transport modules 214 and the unloading transport module 213 are respectively located at the multiple battery carrying modules 220.

[0045] Multiple appearance inspection components 230 are arranged at different battery carrier modules 220. The specific structure of the appearance inspection components 230 can be designed according to actual inspection needs. For example, in some optional embodiments, the multiple appearance inspection components 230 are at least two of the following: cylindrical surface inspection component 231, end face 2D inspection component 232, and end face 3D inspection component 233. In this embodiment, the number of appearance inspection components 230 is three, namely cylindrical surface inspection component 231, end face 2D inspection component 232, and end face 3D inspection component 233.

[0046] The cylindrical surface inspection component 231 is used to detect whether there are appearance defects on the cylindrical surface of the cylindrical battery, while the end face 2D inspection component 232 and the end face 3D inspection component 233 are used to detect whether there are appearance defects on the end face of the cylindrical battery. The structures of the cylindrical surface inspection component 231, the end face 2D inspection component 232, and the end face 3D inspection component 233 may be the same or different. Their structures and inspection principles are well known to those skilled in the art and will not be described in detail here.

[0047] The number of battery carrier modules 220 and intermediate transport modules 214 is designed based on the actual number of appearance inspection components 230. In this embodiment, there are three appearance inspection components 230, three intermediate transport modules 214, and four battery carrier modules 220, of which three are inspection carrier modules 221 and the other is an NG carrier module 222.

[0048] The aforementioned transfer robot assembly 140 is used to transport the cylindrical batteries on the transfer table 121 to the loading and handling module 212, and adjust the spacing of the cylindrical batteries so that the spacing between adjacent cylindrical batteries can meet the placement requirements of the loading and handling module 212.

[0049] The working principle of the detection device 20 according to one embodiment of the present invention is described below. In the initial state, none of the battery carrying modules 220 carry cylindrical batteries, and none of the loading and unloading modules 212, unloading and unloading modules 213, and multiple intermediate transport modules 214 carry cylindrical batteries. First, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213 and multiple intermediate transport modules 214 together to the second position. At this time, the loading transport module 212 is not at the detection and bearing module 221. At this time, the first batch of cylindrical batteries that need to be detected can be placed on the loading transport module 212. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213 and multiple intermediate transport modules 214 together to the first position. At this time, the loading transport module 212 reaches the first detection and support module 221. The loading transport module 212 places the first batch of cylindrical batteries on the first detection and support module 221. At this time, the appearance inspection module arranged at the first detection and support module 221 inspects the cylindrical batteries. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213 and multiple intermediate transport modules 214 together to the second position. At this time, the second batch of cylindrical batteries is placed on the loading transport module 212, while the first intermediate transport module 214 removes the first batch of cylindrical batteries from the first detection and bearing module 221. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213, and multiple intermediate transport modules 214 together to the first position. At this time, the loading transport module 212 reaches the first detection support module 221 again. The loading transport module 212 places the second batch of cylindrical batteries on the first detection support module 221, while the first intermediate transport module 214 transports the first batch of cylindrical batteries to the second detection support module 221. At this time, the appearance inspection modules correspondingly arranged at the first and second detection support modules 221 inspect the cylindrical batteries. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213 and multiple intermediate transport modules 214 together to the second position. At this time, the third batch of cylindrical batteries is placed on the loading transport module 212, while the first intermediate transport module 214 removes the second batch of cylindrical batteries from the first detection and support module 221, and the second intermediate transport module 214 removes the first batch of cylindrical batteries from the second detection and support module 221. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213, and multiple intermediate transport modules 214 together to the first position. At this time, the loading transport module 212 reaches the first detection and support module 221 again. The loading transport module 212 places the third batch of cylindrical batteries on the first detection and support module 221, while the first intermediate transport module 214 transports the second batch of cylindrical batteries to the second detection and support module 221. The second intermediate transport module 214 then transports the first batch of cylindrical batteries to the third detection and support module 221. At this time, the appearance inspection modules correspondingly arranged at the first detection and support module 221, the second detection and support module 221, and the third detection and support module 221 inspect the cylindrical batteries. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213, and multiple intermediate transport modules 214 together to the second position. At this time, the fourth batch of cylindrical batteries is placed on the loading transport module 212, while the first intermediate transport module 214 removes the third batch of cylindrical batteries from the first detection and support module 221, the second intermediate transport module 214 removes the second batch of cylindrical batteries from the second detection and support module 221, and the third intermediate transport module 214 removes the first batch of cylindrical batteries from the third detection and support module 221. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213, and multiple intermediate transport modules 214 together to the first position. At this time, the loading transport module 212 reaches the first detection carrier module 221 again. The loading transport module 212 places the fourth batch of cylindrical batteries on the first detection carrier module 221, while the first intermediate transport module 214 transports the third batch of cylindrical batteries to the second detection carrier module 221. The second intermediate transport module 214 transports the second batch of cylindrical batteries to the third detection carrier module 221. The third intermediate transport module 214 transports the first batch of cylindrical batteries to the NG carrier module 222. At this time, the appearance inspection modules correspondingly arranged at the first detection carrier module 221, the second detection carrier module 221, and the third detection carrier module 221 inspect the cylindrical batteries. Once the first batch of cylindrical batteries is transported to the NG carrier module 222 by the third intermediate transport module 214, the cylindrical batteries that do not meet the appearance requirements can be removed from the NG carrier module 222. Then, the unloading transport module 213 moves the qualified cylindrical batteries away from the NG carrier module 222. Next, the transport drive module 211 moves the loading transport module 212, the unloading transport module 213 and multiple intermediate transport modules 214 together to the first position. At this time, the unloading transport module 213 leaves the NG carrier module 222, and then the cylindrical batteries on the unloading transport module 213 can be removed. Meanwhile, the second batch of cylindrical batteries is transported to the NG carrier module 222 by the third intermediate transport module 214.

[0050] By repeating the above actions, each batch of cylindrical batteries can be sequentially transported to each detection and carrying module 221 for testing. Each time, the transport drive module 211 moves together with the loading transport module 212, the unloading transport module 213, and multiple intermediate transport modules 214, enabling the cylindrical batteries to move to the adjacent battery carrying module 220. This achieves an efficient and rhythmic transport process, and the cylindrical batteries can be tested in a stable posture in the battery carrying module 220 instead of during transport, thus making the testing more accurate.

[0051] Of course, it is also possible to skip designing the NG carrier module 222 and directly cut the material, and discard the cylindrical batteries with appearance problems in other processes.

[0052] Please see Figure 13 The specific structure of the loading and unloading module 212, the unloading and unloading module 213, and the multiple intermediate handling modules 214 can be designed according to actual needs. For example, in some optional embodiments, the loading and unloading module 212, the unloading and unloading module 213, and the multiple intermediate handling modules 214 all include a lifting module 215 and a handling seat 216. The lifting module 215 is driven to connect with the handling seat 216 and is used to drive the handling seat 216 to rise and fall. The handling drive module 211 is driven to connect with the lifting module 215. The handling seat 216 is provided with multiple first battery positioning parts 2161 for positioning and cooperating with cylindrical batteries. After the lifting module 215 lifts the transport seat 216, it can lift the cylindrical battery on the battery carrying module 220 to remove the cylindrical battery. After the lifting module 215 drives the transport seat 216 to descend, the cylindrical battery on the transport seat 216 can be placed on the battery carrying module 220. The removal and placement of the cylindrical battery is achieved by lifting and lowering the transport seat 216.

[0053] The specific structure of the first battery positioning part 2161 can be designed according to actual needs. For example, the first battery positioning part 2161 is a positioning groove provided on the top of the transport seat 216.

[0054] The specific structure of the lifting module 215 can be designed according to actual needs. For example, the lifting module 215 can adopt a structure that can achieve translation, such as a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0055] In some optional embodiments, the battery handling assembly 210 further includes a handling connector 217. The loading handling module 212, multiple intermediate handling modules 214 and unloading handling module 213 are arranged sequentially on the handling connector 217 along the driving direction of the handling drive module 211. The handling drive module 211 is drivenly connected to the handling connector 217, thereby facilitating the synchronous movement of the loading handling module 212, unloading handling module 213 and multiple intermediate handling modules 214 by the battery handling assembly 210. In this embodiment, the lifting module 215 is disposed on the handling connector 217.

[0056] The specific structure of the transport drive module 211 can be selected according to actual needs. For example, the transport drive module 211 can adopt a lead screw drive module, a rotary motor 312 translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. In this embodiment, the transport drive module 211 adopts a cylinder translation drive module, and its output end is connected to the transport connector 217. Of course, in other embodiments, the transport drive module 211 may also include a number of translation drive modules corresponding to the loading transport module 212, the unloading transport module 213, and multiple intermediate transport modules 214. Each translation drive module is driven and connected to the loading transport module 212, the unloading transport module 213, and the multiple intermediate transport modules 214, and then drives the loading transport module 212, the unloading transport module 213, and the multiple intermediate transport modules 214 to move synchronously.

[0057] Please see Figure 14 and Figure 15 In some optional embodiments, the battery carrier module 220 includes two carrier plates 223, which are located on both sides of the loading and unloading transport module 212, the unloading transport module 213, or the intermediate transport module 214. That is, when the transport drive module 211 moves the loading and unloading transport module 212, the unloading transport module 213, and the multiple intermediate transport modules 214 together to the first position, the carrier plates 223 of each battery carrier module 220 are located on both sides of the unloading transport module 213 and the intermediate transport module 214. When the transport drive module 211 moves the loading and unloading transport module 212, the unloading transport module 213, and the multiple intermediate transport modules 214 together to the second position, the carrier plates 223 of each battery carrier module 220 are located on both sides of the loading and unloading transport module 212 and the intermediate transport module 214. Two support plates 223 are provided with multiple second battery positioning parts 2231 facing each other, which are used to position and cooperate with the cylindrical battery. The second battery positioning parts 2231 are arranged sequentially along the driving direction of the transport drive module 211. The number of second battery positioning parts 2231 matches the number of first battery positioning parts 2161. In this embodiment, the transport seat 216 is located between the two support plates 223. When the transport seat 216 is lowered, the two ends of the cylindrical battery can be placed on the corresponding second battery positioning parts 2231 on the two support plates 223 respectively. When the transport seat 216 is raised, the middle part of the cylindrical battery can be lifted, thereby moving the cylindrical battery away from the second battery positioning parts 2231.

[0058] In some alternative embodiments, two support plates 223 are rotatably mounted with multiple support rollers 2232 facing each other, and the second battery positioning part 2231 is a battery positioning space formed between two adjacent support rollers 2232. The support rollers 2232 can better support the cylindrical battery, and the rotatable design of the support rollers 2232 results in rolling friction between the support rollers 2232 and the cylindrical battery, thus reducing friction and protecting the appearance of the cylindrical battery. Furthermore, the outer peripheral surfaces of two adjacent support rollers 2232 are curved, which helps to use the weight of the cylindrical battery to position the cylindrical battery in the exact center of the two adjacent support rollers 2232.

[0059] In some optional embodiments, one of the plurality of appearance inspection components 230 is a cylindrical surface inspection component 231. Since the cylindrical surface of the cylindrical battery is 360° around the cylindrical battery, the cylindrical battery needs to be rotated during inspection. Therefore, the inspection support module 221 corresponding to the cylindrical surface inspection component 231 needs to add a structure to drive the cylindrical battery to rotate. For this purpose, a battery clamping module 224 is provided on the support plate 223. The battery clamping module 224 includes a movable seat 2241 and a telescopic drive module 2242. The movable seat 2241 is movably mounted on the support plate 223. Multiple clamping members 2243 are rotatably mounted on the movable seat 2241. The clamping members 2243 are located on the side of the second battery positioning part 2231. The telescopic drive module 2242 is drivenly connected to the movable seat 2241 and is used to drive the movable seat 2241 toward or away from the second battery positioning part 2231. One of the battery clamping modules 224 of the support plate 223 also includes a rotation drive module 2244, which is drivenly connected to the clamping members 2243. The telescopic drive module 2242 drives the movable seat 2241 to move toward the second battery positioning part 2231, thereby causing the clamping member 2243 to press against the end of the cylindrical battery. The clamping members 2243 on the two support seats cooperate to press the two ends of the cylindrical battery, thereby clamping the cylindrical battery. The rotation drive module 2244 drives the clamping member 2243 on one of the movable seats 2241 to rotate, thereby driving the cylindrical battery to rotate through friction, so that different positions of the cylindrical surface of the cylindrical battery can be detected by the cylindrical surface detection component 231.

[0060] The specific structure of the telescopic drive module 2242 can be selected according to actual needs. For example, the detection translation drive module 240 can be a lead screw drive module, a rotary motor translation drive module 312, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0061] The specific structure of the battery clamping module 224 can be selected according to actual needs. For example, the battery clamping module 224 includes a battery rotation drive motor, multiple first gears and multiple second gears. The first gears are connected to the clamping member 2243, and the second gears mesh with two adjacent first gears. The battery rotation drive motor is driven by one of the first gears or one of the second gears. This example is not limited to this one.

[0062] In some optional embodiments, the detection device 20 of the cylindrical battery detection equipment further includes a detection translation drive module 240, which is drivenly connected to multiple battery carrier modules 220. The appearance detection component 230 includes multiple detection modules 234 for acquiring detection images of cylindrical batteries. The multiple detection modules 234 are arranged sequentially around the battery carrier modules 220 along the driving direction of the detection translation drive module 240. Since the detection modules 234 are usually cameras, in order to improve the accuracy of acquiring detection images, preferably, the detection module 234 usually acquires the detection image of a single cylindrical battery at a time. However, in order to improve handling efficiency, the number of cylindrical batteries handled each time is relatively large. But it would be too costly to arrange a detection module 234 for each cylindrical battery. Therefore, considering both improving detection efficiency and handling efficiency, multiple detection modules 234 are designed, but their number does not exceed the number of cylindrical batteries in a single batch. For example, if the number of cylindrical batteries in a batch is twenty-four, the number of detection modules 234 is... The system uses four detection modules 234. Each time, the four detection modules 234 acquire detection images of four cylindrical batteries. Then, the detection translation drive module 240 moves the battery carrying module 220 by a distance equal to the distance between adjacent cylindrical batteries. The four detection modules 234 can then acquire detection images of another four cylindrical batteries. The detection translation drive module 240 only needs to move the battery carrying module 220 five times, allowing the four detection modules 234 to acquire detection images of twenty-four cylindrical batteries. This reduces the number of detection modules 234 required and increases the detection speed. Of course, the number of cylindrical batteries and the number of detection modules 234 in the same batch can be designed according to actual needs, and this example is not limited to this one.

[0063] The specific structure of the detection translation drive module 240 can be selected according to actual needs. For example, the detection translation drive module 240 can be a lead screw drive module, a rotary motor 312 translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. In this embodiment, the support plates 223 of adjacent battery carrier modules 220 are connected by connecting rods 225. The detection translation drive module 240 adopts a linear motor translation drive module. The detection translation drive module 240 is connected to the support plate 223 of one of the battery carrier modules 220, and the two support plates 223 of the same battery carrier module 220 are connected together. In this way, the detection translation drive module 240 only needs to drive one support plate 223 to move, which can drive all battery carrier modules 220 to move together. After each appearance detection component 230 performs detection, the detection translation drive module 240 synchronously drives all battery carrier modules 220 to move together, and then other cylindrical batteries are detected. This helps to speed up the detection efficiency and facilitates operation.

[0064] In addition, the structure of the detection module 234 can also be designed according to actual needs. The structure of the detection module 234 and the principle of judging whether there are appearance defects in the cylindrical battery by detecting the image are well known to those skilled in the art, and will not be described in detail here.

[0065] It should be noted that the detection module 234 of the cylindrical surface detection component 231, the detection module 234 of the end face 2D detection component 232, and the detection module 234 of the end face 3D detection component 233 may have the same or different structures. Their structures and detection principles are well known to those skilled in the art and will not be described in detail here.

[0066] In some optional embodiments, the unloading device 30 includes an unloading robot assembly 31 and an NG robot assembly 32. The NG robot assembly 32 is arranged on one side of the NG carrier module 222. When the loading and unloading conveying module 212, the unloading and unloading conveying module 213, and the plurality of intermediate conveying modules 214 are in the first position, the unloading and unloading conveying module 213 is on one side of the unloading robot assembly 31. When the cylindrical battery is placed in the NG carrier module 222, if the cylindrical battery is detected as unqualified by the appearance inspection component 230, the unqualified cylindrical battery can be removed from the NG carrier module 222 by the NG robot assembly 32. Qualified cylindrical batteries are moved away from the NG carrier module 222 by the unloading and unloading conveying module 213, and when the unloading and unloading conveying module 213 is in the first position, the unloading robot assembly 31 can move the cylindrical battery away from the unloading and unloading conveying module 213. In this embodiment, the unloading device 30 also includes an NG robot assembly 32 arranged on one side of the NG carrier module 222. The NG robot assembly 32 can transport cylindrical batteries to the NG conveyor line 37 and is used to transport unqualified cylindrical batteries to other locations.

[0067] Please see Figure 16 The specific structure of the unloading robot assembly 31 can be designed according to actual needs. For example, in this embodiment, the unloading robot assembly 31 also includes an unloading multi-axis translation drive module 311, a rotary motor 312, and multiple unloading clamping mechanisms 313. The multi-axis translation drive module is driven and connected to the rotary motor 312 to drive the rotary motor 312 to translate. The rotary motor 312 is correspondingly driven and cooperates with the unloading clamping mechanism 313. The unloading multi-axis translation drive module 311 can be a two-axis translation drive module or a three-axis translation drive module, etc., to realize the translation of the battery clamping mechanism in multiple axes. The principle and structure of the multi-axis translation drive module are well known to those skilled in the art and will not be described in detail here. The unloading clamping mechanism 313 is used to clamp cylindrical batteries, and its structure is well known to those skilled in the art and will not be described in detail here. After the unloading robot assembly 31 is removed from the unloading and handling module 213, the rotary motor 312 drives the unloading clamping mechanism 313 to rotate 90°, thereby returning the cylindrical battery from a horizontal to a vertical position. Since the unloading clamping mechanism 313 can directly clamp the cylindrical battery in the middle, the battery is less likely to fall off after being rotated. Of course, depending on the method of storing the cylindrical battery, the unloading robot assembly 31 can also adopt other suitable structures.

[0068] In some optional embodiments, the unloading device 30 includes a first unloading conveyor line 33, a plurality of second unloading conveyor lines 34, an unloading and handling robot assembly 35, and a tray-loading robot assembly 36. The unloading robot assembly 31 is arranged between the detection device 20 and the first unloading conveyor line 33. The unloading robot assembly 31 is used to clamp the cylindrical batteries on the detection device 20 onto the first unloading conveyor line 33. The first unloading conveyor line 33 and the plurality of second unloading conveyor lines 34 are arranged side by side. The unloading and handling robot assembly 35 is disposed between the first unloading conveyor line 33 and the plurality of second unloading conveyor lines 34. It is used to handle the cylindrical batteries on the first unloading conveyor line 33 onto each of the second unloading conveyor lines 34. The tray-loading robot assembly 36 is disposed on one side of the first unloading conveyor line 33 and the plurality of second unloading conveyor lines 34. It is used to clamp and move the cylindrical batteries on the first unloading conveyor line 33 and the plurality of second unloading conveyor lines 34 away.

[0069] The first unloading conveyor line 33 and multiple second unloading conveyor lines 34 are equivalent to arranging cylindrical batteries in a matrix. The second unloading conveyor lines 34 can also temporarily store cylindrical batteries. Then, the tray loading robot assembly 36 transports the cylindrical batteries on the first unloading conveyor line 33 and multiple second unloading conveyor lines 34 to a suitable position, such as to a battery storage tray.

[0070] The principles and structures of the unloading and handling robot assembly 35 and the palletizing robot assembly 36 are well-known to those skilled in the art and will not be described in detail here.

[0071] The specific structures of the first feeding conveyor line 33, the second feeding conveyor line 34, and the NG conveyor line 37 can be designed according to actual needs. For example, the first feeding conveyor line 33, the second feeding conveyor line 34, and the NG conveyor line 37 can adopt mesh belt conveyor components, roller conveyor components, chain plate conveyor components, or belt conveyor components.

[0072] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
