Description

Technical Field

[0001] The present application relates to the technical field of battery detection, and in particular to a battery industrial CT detection line. Background Art

[0002] Compared with wound batteries, laminated batteries have more advantages in performance, completeness, and space utilization. With the development of new energy vehicles, laminated batteries have gradually occupied a part of the power battery market and are widely used in new energy vehicles. However, laminated batteries have higher process requirements. The lamination process requires each pole piece to be cut twice, and a battery involves dozens of cuts. Each cut has the risk of burrs on the cross section of the pole piece, and misaligned pole pieces will be twisted and rotated during lamination, which affects the quality of the battery. Checking the cutting of the laminate has become a problem that every battery manufacturer has to solve.

[0003] When an existing online industrial CT system detects batteries, it is necessary to place the batteries one by one in a CT detection mechanism for detection. After the battery detection in the CT detection mechanism is completed, the battery in the CT detection mechanism is taken out, and then the next battery is placed in for detection. The batteries are placed in the CT detection mechanism one by one for detection, which affects the detection efficiency of the batteries.

[0060] In one embodiment, see Figure 2 , Figure 7 and Figure 8The first transport mechanism 40 includes a first clamping assembly 41, a first lifting drive assembly 42 and a first lateral drive assembly 43. The first lifting drive assembly 42 is used to drive the first clamping assembly 41 to move up and down (along the Figure 7 The first transverse drive assembly 43 is used to drive the first lifting drive assembly 42 to move along the width direction Y of the feeding conveyor line 10. The first lifting drive assembly 42 can be used to drive the first clamping assembly 41 to move up and down, so that the first transverse drive assembly 43 can drive the first lifting drive assembly 42 to move laterally.

The number of the third drivers 414 can be two, and the two third drivers 414 are respectively connected to the two sliding plates 412 to respectively control the two sliding plates 412 to move, clamp or release the battery 72.

The clamping arm is provided at one end of the clamping plate 411 away from the third slide seat 415, and the clamping arm cooperates with the lower end of the sliding plate 412 to clamp one side of the battery 72 (or jig 70). The adjusting member 413 can be an adjusting screw, and the distance between the clamping arm and the sliding plate 412 can be adjusted by rotating the adjusting screw, so that the structure is simple and convenient for processing and assembly.

The two detection platforms 32 are respectively located on opposite sides of the scanning mechanism 31 along the length direction X of the feeding conveyor line 10. The detection platforms 32 are used to carry the battery 72 and place the battery 72 on the scanning mechanism 31. The scanning mechanism 31 is used to scan the battery 72 to detect the battery 72. When the first transport mechanism 40 transports the two batteries 72 to the detection platforms 32 respectively, the two detection platforms 32 can place the batteries 72 in the scanning mechanism 31 at the same time, so that the scanning mechanism 31 can realize synchronous detection of the two batteries 72.

The cache position 56 is used to store the jig 70, and the cache position 56 is on the transmission path of the second transport mechanism 50. When the third clamping assembly 52 away from the loading conveyor line 10 transfers the jig 70 to the top of the cache position 56, the cache position 56 can support the jig 70, so that the third clamping assembly 52 away from the loading conveyor line 10 can release the jig 70 to the cache position 56, and the third clamping assembly 52 close to the loading conveyor line 10 can transport the jig 70 on the cache position 56 to the loading conveyor line 10. Of course, in other embodiments of the present application, different second lifting drive assemblies 53 can also be used to drive the two third clamping assemblies 52 to rise and fall independently.

[0082] Optionally, the distance between the buffer position 56 and the input end of the loading conveyor line 10 is equal to the distance between the buffer position 56 and the output end of the unloading conveyor line 20. In this way, when the two third clamping assemblies 52 correspond to the buffer position 56 and the output end of the unloading conveyor line 20, they can be raised and lowered synchronously to grab the jig 70 on the buffer position 56 and the jig 70 at the output end of the unloading conveyor line 20 respectively; when the two third clamping assemblies 52 correspond to the buffer position 56 and the input end of the loading conveyor line 10, they can be raised and lowered synchronously to release the jig 70 to the buffer position 56 and the input end of the loading conveyor line 10 respectively.

[0083] In one embodiment, see Figure 2 , Fig. 9 and Fig.10 , the number of the second lifting drive components 53 is two, the power output end of one second lifting drive component 53 is connected to the second clamping component 51, and the power output end of the other second lifting drive component 53 is connected to the third clamping component 52. In this way, the lifting of the second clamping component 51 and the lifting of the third clamping component 52 can be prevented from interfering. Optionally, one second lifting drive component 53 is connected to the second slide 55, and the other second lifting drive component 53 is connected to the second clamping component 51. The two third clamping components 52 are arranged along the length direction of the second slide 55 (such as Fig. 9 The second slide 55 is arranged in the Y-axis direction, and the second clamping assembly 51 is located on the side of the second clamping assembly 51 close to the feeding conveyor line 10. In this way, the lifting and lowering of the two third clamping assemblies 52 can be kept synchronous, and the lifting and lowering of the second clamping assembly 51 and the third clamping assembly 52 can be made independent of each other, avoiding interference between the transmission of the battery 72 and the fixture 70.

In this way, the first belt 12 can support the movement of the fixture 70 to control the moving position of the battery 72. Optionally, the first driving wheel 14 and the first driven wheel 13 are gears, the first belt 12 is a synchronous belt, and a limit bar is provided on the first belt 12. The limit bar is used to push the fixture 70 to move synchronously with the first belt 12 when the first belt 12 is running. In this way, the movement accuracy of the battery 72 can be improved.

After the battery 72 is inspected by the CT inspection mechanism 30, the battery 72 can be judged as a qualified product or a unqualified product according to the preset value; when the battery 72 is a qualified product, the fourth transport mechanism 62 transports the battery 72 and outputs the battery 72; when the battery 72 is an unqualified product, the battery 72 is transported to the first cache line 63 for storage. In this way, the automatic loading of the battery 72 is realized by the third transport mechanism 61, and the battery 72 is sorted after the battery 72 is inspected by the first cache line 63 and the fourth transport mechanism 62.

Optionally, the first driving assembly 613 may include a lifting drive structure and a longitudinal drive structure. The lifting drive structure is used to drive the first grabbing head 611 to lift and lower, and the longitudinal drive structure is used to drive the lifting drive structure to move along the length direction X of the loading conveyor line 10.

[0088] In one embodiment, see Figure 2 , Fig. 9 and Fig.11 The battery industrial CT inspection line 100 further includes a second cache line 64, which is used to transfer the tray 71 from the third transport mechanism 61 to the fourth transport mechanism 62. By using the second cache line 64, the tray 71 carrying the battery 72 during loading can be transferred to the position carrying the qualified products during unloading, so that the automatic transmission of the tray 71 can be realized.

[0089] Optionally, the second cache line 64 includes a second bracket, a second belt, a second driven wheel, a second driving wheel and a fifth driver, wherein the second driven wheel and the second driving wheel are rotatably mounted at both ends of the second bracket along the length direction (Y-axis direction), respectively, and the fifth driver is mounted on the second bracket, and the power output end of the fifth driver is connected to the second driving wheel, and the fifth driver is used to drive the second driving wheel to rotate, so as to drive the second belt to operate, and the carrying tray 71 moves along the length direction of the second bracket.
