[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figures 1 to 10 As shown, this utility model provides an X-ray-based magnetic levitation ring-shaped battery testing machine. In one embodiment, it includes a product transport line 1 with a ring structure, and a loading and positioning device 6, a product testing device 3, and a product unloading device 7 arranged sequentially around the product transport line 1. The loading and positioning device 6 includes a loading frame 61, a first loading mechanism 62 and a second loading mechanism 63 mounted on the loading frame 61, and a loading and positioning mechanism 64 arranged below the first loading mechanism 62 and the second loading mechanism 63. A contour jig 5 is also connected to the product transport line 1. The first loading mechanism 62 is used to transfer the product to be tested onto the loading and positioning mechanism 64, and the loading and positioning mechanism 64 is used to position the product. The second loading mechanism 63 is used to transfer the positioned product onto the contour jig 5. The product testing device 3 is used to test the product on the contour jig 5, and the product unloading device 7 is used to sort and unload the tested products.

[0018] In this embodiment, a barcode scanning mechanism 2 and a fixture dust removal device 4 are also included. The loading and positioning device 6, barcode scanning mechanism 2, product detection device 3, product unloading device 7, and fixture dust removal device 4 are arranged in a clockwise direction around the product transmission line 1 (the product transmission line 1 can be an existing magnetic levitation transmission line). Specifically, the product detection device 3 and the loading and positioning device 6 are respectively arranged on one side of the product transmission line 1. The barcode scanning mechanism 2 is arranged near one end of the product transmission line 1 and is located between the loading and positioning device 6 and the product detection device 3. The fixture dust removal device 4 is arranged near the other end of the product transmission line 1 and is located between the product unloading device 7 and the loading and positioning device 6. The product unloading device 7 includes a defective product sorting robot, a good product unloading robot, and a defective product buffer rack. During operation, the first loading mechanism 62 first grabs the battery from the upstream conveyor line, performs visual inspection, and places it on the loading mechanism. After being positioned by the positioning mechanism 64, the second feeding mechanism 63 places the battery into the conforming fixture 5 of the product conveyor line 1. Subsequently, the product conveyor line 1 transports the battery to the barcode scanning mechanism 2 for barcode scanning, and then to the product detection device 3 for image imaging. During the detection process, the battery can be moved to take images from different positions. After image detection, the background analysis gives a judgment of NG or OK products. OK products are transferred to the next process by the good product unloading robot, while NG products are sorted to the defective product buffer rack by the defective product sorting robot. After sorting, the product conveyor line 1 continues to transport the empty fixture to the fixture dust removal device 4. The fixture dust removal device 4 removes dust from the conforming fixture 5 for recycling. Through this circular transmission method, the conforming fixture 5 can be recycled without the need for external force transfer, saving operation steps and operating space, and improving work efficiency.

[0019] Preferably, in this embodiment, the first feeding mechanism 62 includes a feeding drive mechanism 621, a feeding crossbeam 622 slidably connected to the feeding work frame 61, and a feeding lifting mechanism 623 installed on one side of the feeding crossbeam 622; the feeding drive mechanism 621 is connected to the feeding crossbeam 622 and is used to drive the feeding crossbeam 622 to move; the feeding lifting mechanism 623 is also driven to connect to a feeding lifting frame 624, and a feeding gripper mechanism 625 is also installed at the bottom of the feeding lifting frame 624; the feeding gripper... Mechanism 625 includes a gripper drive motor 6251, which also drives two gripper translation seats 6252. The two gripper translation seats 6252 are arranged opposite to each other, and each gripper translation seat 6252 is connected to a first claw module 6253 at its bottom. Each first claw module 6253 is connected to a first clamping module 6254 on one side. The bottom of the loading lifting frame 624 is also connected to a second claw module 6255, which is located between the two first claw modules 6253.

[0020] In this embodiment, the structure and working principle of the first feeding mechanism 62 and the second feeding mechanism 63 are similar (the working principle of the first feeding mechanism 62 will be mainly described below, and the second feeding mechanism 63 will not be described in detail). The difference is that the first feeding mechanism 62 is provided with four sets of feeding gripper mechanisms 625, and the second feeding mechanism 63 is provided with two sets of feeding gripper mechanisms 625 (and the second feeding mechanism 63 is also provided with a motor module arranged along the moving direction of the vertical feeding beam 622 and used to drive the feeding gripper mechanisms 625 to move). The first feeding mechanism 62 is responsible for grabbing four battery cells at a time from the battery cell material line and placing them on the feeding positioning mechanism 64. After precise positioning, the second feeding mechanism 63 is responsible for picking up the cells at intervals. The material handling process involves picking up two battery cells at a time and placing them onto a fixture on the product transmission line 1 (the placement method is to place one battery cell every other fixture; in practice, there are two sets of the loading and positioning devices 6, each set for loading one type of battery cell, with the two battery cells arranged alternately, i.e., a battery cell of another type is placed between two battery cells of the same type). Meanwhile, the loading lifting mechanism 623 can be a lifting motor, cylinder, or other module that can drive the gripper mechanism to lift and lower, and there are no restrictions on this. The defective product sorting robot and the good product unloading robot of the product unloading device 7 can both adopt the same structure as the loading gripper mechanism 625 or an existing robot, and can be equipped with the corresponding linear module. This utility model will not elaborate further on this.

[0021] Meanwhile, the gripper drive motor 6251 can drive the two gripper translation seats 6252 to move closer or further apart, thereby clamping the product through the first claw module 6253. At the same time, a second claw module 6255 is provided. The first claw module 6253 and the second claw module 6255 can lift the battery from both ends and the middle, respectively, while the first clamping module 6254 can clamp the battery to ensure that the battery is stable and reliable during gripping and handling, and can ensure that the battery is not easily deformed. The gripper drive motor 6251 drives the two gripper translation seats 6252 to open and close by using a synchronous belt or bidirectional screw drive, without any restrictions.

[0022] Furthermore, preferably, in this embodiment, a feeding slide rail assembly 6211 is arranged at each of the top two ends of the feeding work frame 61 along its length direction, and a first rack 6212 is also arranged on one side of each feeding slide rail assembly 6211; two feeding drive mechanisms 621 are provided, and the two feeding drive mechanisms 621 are respectively arranged at one end of the feeding crossbeam 622; the feeding drive mechanism 621 includes a drive connecting plate connected to the feeding crossbeam 622, a feeding drive motor 6213 mounted on the drive connecting plate, and a first gear 6214 mounted on the output shaft of the feeding drive motor 6213; the bottom two ends of the feeding crossbeam 622 are respectively slidably arranged on a feeding slide rail assembly 6211, and the first gear 6214 of each feeding drive mechanism 621 is correspondingly meshed with a first rack 6212. The first gear 6214 on the feeding drive motor 6213 meshes with the first rack 6212. Through gear and rack transmission, the feeding beam 622 can be driven to move along the feeding slide rail assembly 6211, which facilitates the feeding gripper mechanism 625 to transfer products. This transmission method of the dual feeding drive mechanism 621 can ensure the smooth movement of the feeding beam 622 and improve the accuracy and reliability of the feeding process.

[0023] Preferably, in this embodiment, the first claw module 6253 includes a claw mounting plate 62531 connected to the bottom of the claw translation seat 6252, a claw lifting seat 62532 slidably arranged on one side of the claw mounting plate 62531, a first claw connecting plate 62533 connected to one side of the claw lifting seat 62532, and a first lifting block 62534 with an L-shaped structure and its L-shaped vertical end connected to the first claw connecting plate 62533; a claw guide rod is also connected to the claw lifting seat 62532, and the upper part of the claw guide rod is movably arranged through the claw translation seat 6252; a first limiting step is also provided on the top of the claw guide rod; a first spring 62535 is also sleeved on the claw guide rod, and the two ends of the first spring 62535 are respectively connected to the bottom of the claw translation seat 6252 and the top of the claw lifting seat 62532.

The first clamping cylinder 62541 can drive the first clamping seat 62542 to press the battery downward, ensuring that the battery will not slip or loosen during gripping and handling; while the second gripper module 6255 includes a second lifting block 62551, a gripper connecting frame 62552 connected to the bottom of the loading lifting frame 624, a gripper translation cylinder 62553 arranged in the longitudinal direction of the vertical gripper drive motor 6251 and installed at the bottom of the gripper connecting frame 62552, and a translation bracket 62554 connected to the output shaft of the gripper translation cylinder 62553; A gripper lifting block 62555 is slidably connected to one side of the translation bracket 62554, and a second gripper connecting plate is connected to one end of the gripper lifting block 62555; the second lifting block 62551 has an L-shaped structure, and the L-shaped vertical end of the second lifting block 62551 is connected to the second gripper connecting plate, and the L-shaped horizontal end of the second lifting block 62551 extends in the direction between the two first gripper modules 6253; a second spring 62556 is also connected between the top of the gripper lifting block 62555 and the bottom of the translation bracket 62554.

[0025] The gripper translation cylinder 62553 drives the translation bracket 62554 to move horizontally, thereby causing the second lifting block 62551 to lift the battery. Simultaneously, the gripper lifting block 62555 floats up and down thanks to the elastic support of the second spring 62556. The second lifting block 62551 lifts the battery from the middle position, working in conjunction with the first gripper module 6253 to ensure the battery's stability and reliability during gripping and handling. Furthermore, a first sensing plate is connected to the bottom of the gripper drive motor 6251. The first sensing plate is positioned between the two first gripper modules 6253, and a first sensor 6256 is mounted on it.
