Description

TECHNICAL FIELD

[0002] In the production process of a battery, the appearance of a pole piece needs to be detected for defects to ensure that it is qualified for shipment. For example, Chinese Invention Patent CN202311636906.8 discloses a battery cell appearance detection device, which includes a detection conveying line, a detection device, a feeding conveying device, and a discharging conveying device. The detection conveying line is two in number and is arranged side by side. The detection device is arranged on the flow path of the detection conveying line and corresponds to the detection conveying line one by one. The feeding conveying device includes two first clamps corresponding to the detection conveying line one by one, so as to simultaneously convey the battery cells to be detected to each detection conveying line. The discharging conveying device includes two second clamps corresponding to the detection conveying line one by one, so as to simultaneously convey the detected battery cells away from each detection conveying line.

[0003] In the prior art, in order to connect the upstream and downstream of the detection device, an inlet structure is arranged at the feeding conveying device, and an outlet structure is arranged at the discharging conveying device. The inlet structure and the outlet structure each include a line body and a transfer mechanism. The line body of the inlet structure is adapted to receive the first carrier disc flowing from the upstream to a preset position. The first carrier disc contains two battery cells to be detected, so as to be fed by each first clamp, and then the transfer mechanism can move the empty first carrier disc away from the line body. The transfer mechanism of the outlet structure is adapted to move the empty second carrier disc to the preset position of the line body of the outlet structure. The second carrier disc and the first carrier disc are the same structure, so as to be discharged by each second clamp, and then the line body conveys the second carrier disc containing the battery cells to the downstream station.

When the carrier 310 is at the loading position, the batteries 320 on the carrier 310 are arranged side by side along the Y-axis direction and are in the same straight line as the unloading position and the feeding device 600 in parallel to the Y-axis. When the unloading conveying device 500 works, the second taking and placing mechanism 530 close to the waste collecting device 700 is adapted to carry the unqualified batteries 320 from each detection conveying line 100 to the waste collecting device 700 under the driving of the second Y-axis module 510 and the second Z-axis module 520. The other two second taking and placing mechanisms 530 are adapted to carry the qualified batteries 320 from the unloading position of each detection conveying line 100 to the feeding device 600 or the carrier 310 at the loading position under the driving of the second Y-axis module 510 and the second Z-axis module 520.

[0072] Since in a preferred embodiment, the single first taking and placing mechanism 430 is provided with two first clamping jaws 440, correspondingly, each second taking and placing mechanism 530 is also arranged with two second clamping jaws 540 along the X-axis direction to match the feeding efficiency. At this time, the number of the unloading position is two, and the feeding device 600 and the loading position of each detection conveying line 100 correspond to two to correspond to the second clamping jaw 540 one by one, so that the second taking and placing mechanism 530 can simultaneously carry two batteries 320 on a detection conveying line 100 at a time to be placed into the carriers 310 at different unloading positions. The structure of the second taking and placing mechanism 530 is the same as that of the first taking and placing mechanism 430, which will not be described here again.

[0073] Further, referring to FIG. 6, Figure 8 The feeding device 600 includes a first lifting module 610 and a feeding table 620 in driving connection with the first lifting module 610. The first lifting module 610 is a linear module arranged along the Z-axis direction and is adapted to drive the feeding table 620 to lift along the Z-axis direction. The feeding table 620 is used to accommodate a single battery 320, and the feeding table 620 is provided with a positioning structure to position the battery 320. Since the second taking and placing mechanism 530 is provided with two second clamping jaws 540, the feeding device 600 is correspondingly provided with two. By adopting the lifting type feeding table 620, when the second taking and placing mechanism 530 needs to place or take the battery 320 from one of the feeding tables 620, the second taking and placing mechanism 530 does not need to lift, avoiding interference with the other feeding table 620.

[0074] Further, referring to FIG. 6, Figure 9As shown, the waste collecting device 700 comprises a buffer mechanism 710 and a hopper 720. The buffer mechanism 710 comprises a second lifting module 711 and a transfer line 712 in driving connection with the second lifting module 711, and the second taking and placing mechanism 530 is adapted to transfer the battery 320 to the transfer line 712. The hopper 720 comprises a buffer line 721 for storing the unqualified batteries 320, and the buffer line 721 is arranged in parallel along the Z-axis direction. The conveying directions of the transfer line 712 and the buffer line 721 are both parallel to the X-axis direction, and the second lifting module 711 is a linear module arranged along the Z-axis direction, which is adapted to drive the buffer line 721 to ascend and descend along the Z-axis direction, so that the discharge end of the transfer line 712 corresponds to the feeding end of different buffer lines 721.

[0075] Further, referring to Figures 1 to 3 As a preferred embodiment, the double-channel appearance detection system further comprises a transfer device 800 arranged corresponding to each detection conveying line 100, and the transfer device 800 is adapted to move the battery 320 detected as unqualified away from the discharge position of the detection conveying line 100, and the second taking and placing mechanism 530 is adapted to clamp the battery 320 on the transfer device 800 and carry it to the waste collecting device 700. In this embodiment, the number of the transfer device 800 is four, corresponding to the discharge position one by one. Two of the transfer devices 800 are arranged in parallel between the two detection conveying lines 100, and the other two are arranged in parallel between the detection conveying line 100 adjacent to the waste collecting device 700 and the waste collecting device 700, so that the whole system is more compact and the occupied space is reduced.

[0076] Due to the structure of the second taking and placing mechanism 530, the second taking and placing mechanism 530 is relatively slow in grabbing the battery 320. By using the above structure, the battery 320 detected as unqualified on the detection conveying line 100 can be quickly moved away from the discharge position, improving the discharging efficiency. In addition, when the second taking and placing mechanism 530 is of the double-claw type, there are two discharge positions on a single detection conveying line 100, and there are both qualified and unqualified batteries. The arrangement of the transfer device 800 can avoid the interference between the qualified and unqualified batteries 320, improve the reliability of the second taking and placing mechanism 530, and also avoid the interference between the second taking and placing mechanism 530 for grabbing the qualified battery 320 and the second taking and placing mechanism 530 for grabbing the unqualified battery 320, so that they can take the batteries at the same time, improving the discharging efficiency.

[0077] Further, referring to Figure 11As shown, the transfer device 800 is located at the side of the detection conveying line 100 in the Y-axis direction, which comprises a third Y-axis module 810, an upper fork assembly 820 and a lower fork assembly 830. The third Y-axis module 810 is a linear module arranged along the Y-axis direction, and the output end of the third Y-axis module 810 is provided with a mounting frame 811. The upper fork assembly 820 and the lower fork assembly 830 are both arranged on the mounting frame 811, and the third Y-axis module 810 is adapted to drive the upper fork assembly 820 and the lower fork assembly 830 to move along the Y-axis direction.

[0078] The upper fork assembly 820 comprises an upper fork driving member 821 arranged on the mounting frame 811 and an upper fork 822 in driving connection with the upper fork driving member 821. The lower fork assembly 830 comprises a lower fork driving member 831 arranged on the mounting frame 811 and a lower fork 832 in driving connection with the lower fork driving member 831. The upper fork driving member 821 and the lower fork driving member 831 are both linear air cylinders. The hollow region of the carrier 110 is adapted to the upper fork 822 and the lower fork 832. The upper fork 822 and the lower fork 832 are adapted to be moved to both sides of the battery 320 in the Z-axis direction through the hollow region under the driving of the third Y-axis module 810, and to clamp the battery 320 under the driving of the upper fork driving member 821 and the lower fork driving member 831.

[0079] Preferably, the lower fork 832 comprises at least two lower fork bars 833 corresponding to the two hollow regions separated by the support block 113, and the upper fork 822 comprises at least two upper fork bars 823 corresponding to the lower fork bars 833 one by one, so that the transfer device 800 can smoothly and reliably transfer the battery 320.

[0080] In an embodiment, when the upper fork 822 and the lower fork 832 cooperate to clamp the battery 320, the upper fork 822 and the lower fork 832 do not protrude relative to the battery 320 in the X-axis direction. Since the second clamping jaw 540 is used to clamp both sides of the battery 320 in the X-axis direction, i.e., to clamp different regions of the battery 320, the second clamping jaw 540 and the transfer device 800 can effectively avoid interfering with each other. Indeed, in another embodiment, the top surface of the lower fork bar 833 used to contact the bottom of the battery 320 is inwardly recessed to form a groove 8331, which is a through structure in the X-axis direction. The groove 8331 is adapted to the clamping piece 463 of the second clamping jaw 540, so that the clamping piece 463 can be inserted into the groove 8331 to carry and clamp the battery 320. The clamping piece 463 can be clamped in place while effectively avoiding interference with the lower fork 832.

[0081] When the transfer device 800 works, the third Y-axis module 810 drives the upper prongs 822 and the lower prongs 832 to be inserted into the upper side and the lower side of the battery 320 along the Y-axis direction, then the upper prongs 822 and the lower prongs 832 are clamped to the battery 320 under the drive of the upper prong driving member 821 and the lower prong driving member 831, and the battery 320 is moved away from the carrier 110 under the drive of the third Y-axis module 810, then the second taking and placing mechanism 530 can be moved to the upper side of the battery 320 along the Y-axis direction, and is moved downward to clamp the battery 320 on the transfer device 800, then the upper prongs 822 and the lower prongs 832 are loosened from the battery 320, and are separated from the battery 320 under the drive of the third Y-axis module 810, so as not to hinder the second taking and placing mechanism 530 from rising and moving to the waste collecting device 700 along the Y-axis direction.

[0082] The working process of the double-channel appearance detection system is as follows: the flow line 300 drives the carrier disc 310 carrying the batteries 320 to be detected to move to the taking position, the two first taking and placing mechanisms 430 of the feeding carrying device 400 are moved to the upper side of the taking position along the Y-axis direction, the first clamping jaws 440 are corresponded to the batteries 320 one by one, then the first clamping jaws 440 are lowered along the Z-axis direction to grab the batteries 320, then the first clamping jaws 440 are raised and moved to the detection conveying line 100 along the Y-axis direction to place the batteries 320 into the carriers 110 at the feeding position; the detection conveying line 100 drives the batteries 320 to flow through the detection device 200 to realize the detection of the batteries 320, and finally flows to the discharging position, while the flow line 300 drives the empty carrier disc 310 to move to the discharging position; if all the batteries 320 are qualified, the two second taking and placing mechanisms 530 of the discharging carrying device 500 are moved to the upper side of the discharging position along the Y-axis direction, the second clamping jaws 540 are corresponded to the batteries 320 one by one, then the second clamping jaws 540 are lowered along the Z-axis direction to grab the batteries 320, then the second clamping jaws 540 are raised and moved to the discharging position along the Y-axis direction to place the batteries 320 into the empty carrier disc 310, and the flow line 300 can drive the carrier disc 310 to flow out; if the batteries 320 in the same carrier disc 310 are both qualified and unqualified, the transfer device 800 corresponding to the unqualified battery 320 moves the battery 320 away from the detection conveying line 100, the second taking and placing mechanism 530 close to the waste collecting device 700 takes the battery 320 away from the transfer device 800 and moves to the waste collecting device 700, while one of the other two second taking and placing mechanisms 530 can move the remaining qualified battery 320 to the feeding device 600, when the subsequent carrier disc 310 has a single qualified battery 320, the second taking and placing mechanism 530 supplements the battery 320 in the feeding device 600 into the carrier disc 310, so that the carrier disc 310 flowing out of the flow line 300 is an empty carrier disc 310 or a carrier disc 310 full of qualified products, avoiding the situation that the carrier disc 310 has a single qualified battery 320.

[0083] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made according to the content of the present application and the accompanying drawings, is also included in the patent protection scope of the present application.
