DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0026] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0027] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0028] In the description of the utility model, it should be noted that if the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the utility model product is used, only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0029] In addition, if the terms "first", "second" and the like appear, they are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0030] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0031] The battery piece rejection device provided by the related art is usually a suction cup device, which comprises a motor, a lead screw, a sliding block and a suction cup, the motor is in transmission connection with the lead screw, the lead screw is in threaded connection with the sliding block, and the suction cup is assembled on the sliding block; when the AOI (automatic optical inspection) detects that the battery piece conveyed by the conveying mechanism has defects, the lead screw is driven to rotate by the motor, so that the sliding block slides along the length extension direction of the lead screw, and the suction cup is driven to move to be able to adsorb the battery piece conveyed on the conveying mechanism, then the lead screw is driven to rotate reversely by the motor, so that the sliding block reversely slides along the length extension direction of the lead screw, to drive the suction cup to take the battery piece away from the conveying mechanism, and then the battery piece taken out by the suction cup is placed in the defective piece receiving box.

[0032] The suction disc device not only has a large size and needs to occupy a large installation space, but also when the battery piece is removed by the suction disc, the suction disc can reliably remove the battery piece for defects such as edge collapse, angle defect, and foreign matter on the surface. However, when the battery piece is severely fragmented or even broken into pieces, the suction disc cannot reliably adsorb the battery piece, which leads to failure of the battery piece removal. At this time, the machine often alarms, and manual removal is required, which increases the machine downtime and reduces the production. In addition, when the defect of the battery piece to be removed is fragmentation, the suction disc can absorb most of the battery fragments, but a small part of the fragments will still be left on the conveying mechanism. This part of the fragments is not easy to be identified, and thus the fragments will not be removed again, which leads to the fragments remaining on the conveying mechanism and causing the battery pieces conveyed subsequently by the conveying mechanism to be scratched by the fragments, thereby reducing the yield of the same batch of battery pieces.

[0033] The removed battery piece is placed in the receiving box by the suction disc, which is difficult to stack neatly. When the battery piece in the receiving box is collected manually, it is easy to be scratched.

[0034] To improve the above problems, the present embodiment provides a battery piece removal device 010 (as shown in Figure 1 which can be used in a battery production system. The battery piece removal device 010 will be described in detail below in combination with the drawings.

[0035] The present embodiment provides a battery piece production system, which includes a battery piece removal device 010. Please refer to Figure 1 and Figure 2 The battery piece removal device 010 includes a driving mechanism 200 and two conveying mechanisms 100. The two conveying mechanisms 100 are used to support and convey battery pieces. The driving mechanism 200 is drivingly connected to at least one of the two conveying mechanisms 100. The driving mechanism 200 is used to drive one of the conveying mechanisms 100 away from or close to the other conveying mechanism 100, so that the battery piece can fall between the two conveying mechanisms 100. In this way, when the battery piece is removed, the distance between the two conveying mechanisms 100 only needs to be increased, so that the battery piece to be removed can fall between the two conveying mechanisms 100, without the need to adsorb the battery piece by the suction disc, thereby improving the problem that the battery piece is easily removed. Even if the battery piece to be removed is broken into pieces, the fragmented battery piece can also fall between the two conveying mechanisms 100, which are separated, thereby reducing the situation that the fragments are left on the conveying mechanism 100. After the battery piece is removed, the subsequent battery piece conveying is improved by using the conveying mechanisms 100 that are close to each other, thereby improving the problem that the subsequent battery piece is scratched by the remaining fragments, and thereby improving the yield of the same batch of battery pieces.

[0036] Optionally, the two conveying mechanisms 100 are arranged at intervals, and the driving mechanism 200 is in driving connection with the two conveying mechanisms 100, for driving the two conveying mechanisms 100 to move close to or away from each other; in this way, the two conveying mechanisms 100 moving away from each other can reliably remove the battery piece.

[0037] Of course, in other embodiments, the driving mechanism 200 can be in driving connection with only one of the conveying mechanisms 100.

[0038] It should be noted that the battery piece removing device 010 of the present embodiment assembles the driving mechanism 200 and the two conveying mechanisms 100 into one body, without the need for additional assembly on the suction cup device, which can reduce the area occupied by the entire machine; moreover, the completeness of the battery piece removing process is improved, and the machine will not alarm due to the failure of the piece kicking, and manual removal will reduce the machine downtime and improve the yield.

[0039] The structure of the driving mechanism 200 can be selected as needed; refer to Figure 1 and Figure 2 The driving mechanism 200 of the present embodiment is a lead screw 220 mechanism, which includes a motor 210 and a lead screw 220, the lead screw 220 is in driving connection with the output shaft of the motor 210, the lead screw 220 is in threaded connection with the two conveying mechanisms 100, when the output shaft of the motor 210 drives the lead screw 220 to rotate around its own rotation axis, the lead screw 220 drives the two conveying mechanisms 100 to move close to or away from each other; wherein the lead screw 220 includes a first threaded segment 221 and a second threaded segment 222 connected with each other, the first threaded segment 221 is in driving connection with the output shaft of the motor 210, the first threaded segment 221 is in driving connection with one of the conveying mechanisms 100, the second threaded segment 222 is in driving connection with the other conveying mechanism 100, and the screw directions of the first threaded segment 221 and the second threaded segment 222 are opposite. In this way, only one motor 210 can be used to drive the two conveying mechanisms 100 to move synchronously, reducing the number of motors 210 and lowering the cost.

[0040] Optionally, the connection mode of the first threaded segment 221 and the second threaded segment 222 includes but is not limited to one-piece forming, welding.

[0041] Of course, in other embodiments, the driving mechanism 200 includes two driving assemblies, the two driving assemblies are in driving connection with the two conveying mechanisms 100 one by one, so as to drive the two conveying mechanisms 100 to move respectively by the two driving assemblies, and move close to or away from each other. The driving assembly can be selected as needed, such as a lead screw 220 driving assembly, a gear and rack driving assembly, etc., which is not limited here.

[0042] Refer to Figure 1 and Figure 2The conveying mechanism 100 of the embodiment comprises a bracket 110 and a conveying assembly 120 arranged on the bracket 110, and the two conveying assemblies 120 are used together to support and convey the battery piece. The bracket 110 is in transmission connection with the driving mechanism 200. Specifically, the bracket 110 is in transmission connection with the screw rod 220, and the bracket 110 of one of the conveying mechanisms 100 is in threaded connection with the first threaded section 221 of the screw rod 220, and the bracket 110 of the other conveying mechanism 100 is in threaded connection with the second threaded section 222. The transmission connection between the conveying assembly 120 and the driving mechanism 200 is realized through the bracket 110, which can avoid the interference between the driving mechanism 200 and the conveying assembly 120 in supporting and conveying the battery piece, i.e., the reliability of the conveying assembly 120 in conveying the battery piece is ensured.

[0043] Optionally, the bracket 110 comprises a first support 111 and a second support 112 connected with the first support 111. The first support 111 is in transmission connection with the driving mechanism 200, and the first support 111 of one of the conveying mechanisms 100 is located on the side of the corresponding second support 112 facing the other conveying mechanism 100, and the conveying assembly 120 is assembled on the second support 112. The assembly of the conveying assembly 120 and the driving mechanism 200 on the second support 112 and the first support 111, respectively, can effectively improve the functional interference between the conveying assembly 120 and the driving mechanism 200, i.e., the reliable support and conveying of the battery piece by the conveying assembly 120 and the reliable driving of the two conveying assemblies 120 to move closer to or farther away from each other by the driving mechanism 200 are ensured.

[0044] Further, the second support 112 and the screw rod 220 of the driving mechanism 200 are connected to the upper and lower ends of the first support 111, respectively. The screw rod 220 is in threaded connection with the first support 111, and the connection mode of the second support 112 and the first support 111 comprises but is not limited to integral molding, welding, and bonding.

[0045] Optionally, the conveying assembly 120 is a belt conveying assembly, which comprises a conveying belt 121 and at least two conveying wheels 122.

The conveying belt 121 is used to support the battery piece, and the conveying assemblies 120 of the two conveying mechanisms 100 are oppositely arranged, and the support surfaces of the conveying belts 121 of the two conveying mechanisms 100 are located on the same horizontal plane. When the at least two conveying wheels 122 rotate to drive the conveying belt 121 to move, the conveying belt 121 can drive the battery piece supported thereby to move. The belt conveying assembly can more reliably support and convey the battery piece and is less likely to scratch the surface of the battery piece.

[0046] Further, the conveying assembly 120 comprises two conveying wheels 122, and the conveying belt 121 is tensioned on the two conveying wheels 122; one of the conveying wheels 122 is a driving wheel, and the driving wheel is in driving connection with the motor; the other conveying wheel 122 is a driven wheel, and the two conveying wheels 122 are respectively rotatably arranged at two ends of the second support 112; when the motor drives the driving wheel to rotate, the driving wheel drives the conveying belt 121 to move, and the driven wheel is synchronously rotated by the conveying belt 121.

[0047] Of course, in other embodiments, the number of the conveying wheels 122 can also be three, four, etc., and the plurality of conveying wheels 122 are sequentially rotatably arranged along the length extension direction of the second support 112, which is not specifically limited here.

[0048] With reference to Figure 1 and Figure 2 The battery piece removing device 010 of the embodiment comprises a receiving box 300, and the two conveying mechanisms 100 are spaced apart and distributed, and the receiving box 300 is arranged between the two conveying mechanisms 100 and used for receiving the battery pieces falling from between the two conveying mechanisms 100. Through the arrangement of the receiving box 300, the removed battery pieces can be collected and transferred together, which can reduce the labor amount of manual work and improve the efficiency.

[0049] Optionally, the receiving box 300 is arranged between the first supports 111 of the two conveying mechanisms 100 and is spaced apart from the conveying assembly 120 in the vertical direction; in this way, the receiving box 300 and the battery pieces received in the receiving box 300 can avoid interfering with the support and conveying of the battery pieces by the conveying assembly 120.

[0050] Optionally, the receiving box 300 has a receiving surface 310, and the receiving surface 310 is opposite to the gap between the conveying assemblies 120 of the two conveying mechanisms 100 and used for receiving the falling battery pieces. In this way, the reliability of the battery pieces falling into the receiving box 300 can be improved.

[0051] Of course, in other embodiments, the receiving box 300 can be provided with a receiving groove, and the receiving groove is opposite to the gap between the conveying assemblies 120 of the two conveying mechanisms 100 and used for receiving the falling battery pieces.

[0052] It should be noted that arranging the receiving box 300 between the conveying assemblies 120 of the two conveying mechanisms 100 can help to improve the stacking neatness of the battery pieces received thereby, and thus reduce the problem that the defective battery pieces are easily scratched when manually removed.

[0053] The battery piece removing device 010 of the embodiment further comprises a detection mechanism 400, for example, an AOI (Automatic Optical Inspection) mechanism, which is arranged above the two conveying mechanisms 100 at intervals, and is used to detect whether the battery pieces conveyed by the two conveying mechanisms 100 are defective battery pieces, so that the defective battery pieces can be removed in time when the detection mechanism 400 detects that the battery pieces conveyed by the two conveying mechanisms 100 are defective battery pieces.

[0054] The working principle of the battery piece removing device 010 of the battery piece production system of the embodiment comprises the following steps: when the battery pieces conveyed by the conveying assemblies 120 of the two conveying mechanisms 100 are defective battery pieces, the two conveying mechanisms 100 are driven to move away from each other by the driving mechanism 200, so that the defective battery pieces fall from between the two conveying mechanisms 100 to the receiving box 300; then the two conveying mechanisms 100 are driven to move close to each other and reset by the driving mechanism 200, and the conveying of the subsequent battery pieces can be performed.

[0055] In summary, the battery piece removing device 010 of the embodiment can be used in the battery piece production system, and the battery piece removing device 010 can improve the success rate of battery piece removal, and can improve the problem of the fragments falling from the residual battery pieces on the conveying mechanism 100, so as to improve the problem of the residual fragments scratching the battery pieces conveyed subsequently by the conveying mechanism 100, and to improve the yield of the battery pieces produced in the same batch; the battery piece removing device 010 occupies a small area, and is more convenient to install and use.
