[0059] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0060] Since the structure of the battery piece collecting box used by the battery piece sorting machine is quite different from that of the feeding box used by the battery string welding equipment, the battery pieces collected in the battery piece collecting box need to be picked up one by one and transferred to the feeding box of the battery string welding equipment. This transfer process not only affects the production efficiency, but also easily causes the battery pieces to be contaminated. In order to solve this problem, the present application provides a battery piece collecting device which can save the transfer of battery pieces between two different structure boxes, thereby improving the production efficiency and avoiding the contamination of battery pieces.

[0061] As shown in Figure 1 The battery piece collecting device in the embodiment of the present application includes a main conveying line 1, a material collecting rack 2, a material collecting mechanism 3, and a material box transfer mechanism 4, wherein:

[0062] The main conveying line 1 is configured to convey the battery pieces that have passed the detection, and a battery piece discharging station is arranged on the conveying path of the main conveying line 1.

[0063] The receiving rack 2 is arranged at the side of the main conveying line 1 and used to support the box pad 100.

[0064] The receiving mechanism 3 is arranged above the main conveying line 1 and used to pick up the battery pieces conveyed to the battery piece unloading station and stack the picked-up battery pieces on the box pad 100 on the receiving rack.

[0065] The box transfer mechanism 4 is used to support and convey the box without the box pad and place the box pad stacked with the battery pieces on the receiving rack 2 into the box to obtain the box filled with the battery pieces.

[0066] The box transfer mechanism 4 is also used to convey the box filled with the battery pieces to the next station. For example, the box filled with the battery pieces is conveyed to the AGV transfer mechanism of the next station, and the AGV transfer mechanism is used to transfer the box filled with the battery pieces to the battery string welding device to realize the feeding of the battery string welding device.

[0067] As can be seen, the receiving rack 2 supports the box pad, so that the receiving mechanism 3 can stack the battery pieces on the box pad 100. The box transfer mechanism 4 places the box pad 100 stacked with the battery pieces into the box without the box pad, thereby completing the receiving of the battery pieces by the box.

[0068] The receiving device provided by the embodiment of the present application can directly receive the battery pieces conveyed on the main conveying line 1 into the split box with the box pad of the battery string welding device and directly supply the box filled with the battery pieces to the battery string welding device. In this way, the transfer of the battery pieces between the boxes with different structures is avoided, thereby improving the production efficiency and avoiding the pollution of the battery pieces.

[0069] As shown in FIG. 2, the receiving rack 2 has a plurality of receiving positions, and each receiving position is provided with a lifting hole 21. Figures 2 to 3 Of course, the receiving rack 2 can have only one receiving position, and the receiving rack 2 is provided with only one lifting hole 21. The lifting hole 21 can be provided with a shape similar to the box pad 100, that is, a substantially rectangular shape, and the size of the lifting hole 21 is greater than the size of the box pad 100, so that the box pad 100 can pass through the lifting hole 21 freely.

[0070] The lifting hole 21 is provided with a support portion 22, and the support portion 22 includes a first supporting plate 221 and a second supporting plate 222. The first supporting plate 221 is slidingly connected to the first side of the lifting hole 21 and is configured to be able to extend into the lifting hole 21 or withdraw from the lifting hole 21. The second supporting plate 222 is slidingly connected to the second side opposite to the first side of the lifting hole 21 and is configured to be able to extend into the lifting hole 21 or withdraw from the lifting hole 21.

[0071] When the first supporting plate 221 and the second supporting plate 222 are both extended into the jacking through hole 21, the first supporting plate 221 and the second supporting plate 222 are used to cooperate with bearing a magazine pad 100. When the first supporting plate 221 and the second supporting plate 222 are both withdrawn from the jacking through hole 21, the jacking through hole 21 can be used for the magazine pad 100 to pass through.

[0072] The magazine transfer mechanism 4 is arranged below the material receiving frame 2, and is used to transport the magazine without the magazine pad to the lower side of the jacking through hole 21, and to jacking up the magazine pad 100 with the battery pieces stacked thereon through the jacking through hole 21 to separate from the first supporting plate 221 and the second supporting plate 222. The magazine transfer mechanism 4 is also used to drive the magazine pad 100 with the battery pieces stacked thereon to drop through the jacking through hole 21 and fall into the magazine without the magazine pad when the first supporting plate 221 and the second supporting plate 222 are both withdrawn from the jacking through hole.

[0073] The cooperation of the material receiving frame 2, the magazine transfer mechanism 4 and the piece receiving mechanism 3 in the piece receiving process is as follows:

[0074] The first supporting plate 221 and the second supporting plate 222 are controlled to be extended into the jacking through hole 21, and the magazine pad 100 is placed on the first supporting plate 221 and the second supporting plate 222. At the same time, the magazine transfer mechanism 4 transports the battery magazine without the magazine pad to the lower side of the jacking through hole 21.

[0075] The piece receiving mechanism 3 picks up the battery pieces from the battery piece unloading station, and stacks the battery pieces on the magazine pad 100 until the number of the battery pieces stacked on the magazine pad 100 reaches a predetermined number.

[0076] The magazine transfer mechanism 4 is controlled to jacking up the magazine pad 100 through the jacking through hole 21 to separate from the first supporting plate 221 and the second supporting plate 222, and the first supporting plate 221 and the second supporting plate 222 are controlled to be withdrawn from the jacking through hole 21.

[0077] Finally, the magazine transfer mechanism 4 is controlled to drop, thereby driving the magazine pad 100 with the battery pieces stacked thereon to drop through the jacking through hole 21 and fall into the magazine without the magazine pad. Thus, the magazine filled with the battery pieces is obtained.

[0078] Optionally, the magazine transfer mechanism 4 first transports the magazine with the magazine pad to the lower side of the jacking through hole 21, and jacks up the magazine pad 100 in the magazine through the jacking through hole 21 to the upper side of the jacking through hole 21 when the first supporting plate 221 and the second supporting plate 222 are both withdrawn from the jacking through hole 21.

[0079] After the first supporting plate 221 and the second supporting plate 222 are both extended into the jacking through hole, the magazine transfer mechanism 4 drives the jacked magazine pad 100 to drop and fall onto the first supporting plate 221 and the second supporting plate 222.

[0080] Thus, the magazine transfer mechanism 4 places the magazine pallet 100 of the magazine to be collected onto the first and second pallets 221 and 222, and simultaneously obtains a magazine without the magazine pallet placed thereon.

[0081] Optionally, the first and second pallets 221 and 222 have the same structure and each include a bearing layer 225 and a positioning layer 226, wherein the bearing layer 225 is slidingly connected to the collecting frame 2, and the positioning layer 226 is located on the bearing layer 225. The end of the bearing layer 225 extends out of the positioning layer 226 towards the jacking through hole 21 to bear one end (e.g. one side edge) of the magazine pallet 100. The end of the positioning layer 226 towards the jacking through hole 21 is formed with a positioning protrusion 227 which is matched with the positioning groove on the end of the magazine pallet 100.

[0082] One end of the magazine pallet 100 is borne on the bearing layer 225 of the first pallet 221, and the positioning protrusion 227 of the first pallet 221 is clamped into the positioning groove on the one end of the magazine pallet 100. The other end of the magazine pallet 100 is borne on the bearing layer 225 of the second pallet 222, and the positioning protrusion 227 of the second pallet 222 is clamped into the positioning groove on the other end of the magazine pallet 100. Thus, the support stability of the first and second pallets 221 and 222 to the magazine pallet 100 is ensured, and the movement of the pallet is avoided.

[0083] As shown in Figures 2 to 3 Optionally, the jacking through hole 21 is further provided with a limiting portion 23 and a regularizing portion 24, wherein the limiting portion 23 is arranged at the adjacent first and second edges of the jacking through hole 21, and the regularizing portion 24 is arranged at the adjacent third and fourth edges of the jacking through hole 21, wherein the first edge is opposite to the third edge, and the second edge is opposite to the fourth edge. The regularizing portion 24 is configured to push the battery sheet on the first and second pallets 221 and 222 towards the limiting portion 23 and abut against the limiting portion 23 to regularize the battery sheet.

[0084] Optionally, after the collecting mechanism 3 places one battery sheet on the magazine pallet 100 on the first and second pallets 221 and 222, the regularizing portion 24 immediately pushes the battery sheet towards the limiting portion 23, so that the two adjacent edges of the battery sheet abut against the limiting portion 23 at the first and second edges, respectively. Thus, the regularizing of the battery sheets stacked on the magazine pallet during the collecting process is realized, and the edge alignment of the battery sheets stacked into a stack is ensured.

[0085] As shown in Figure 3 Optionally, the limiting portion 23 includes a plurality of columns distributed at the first and second edges. For example, as shown in Figure 3As shown, the limiting part 23 includes four limiting columns, two of which are arranged at the first edge of the jacking through hole 21, and the other two are arranged at the second edge of the jacking through hole 21.

[0086] The shaping part 24 includes a first shaping unit 241 and a second shaping unit 242, wherein: the first shaping unit 241 includes a first shaping driving member 243 and a first shaping plate 244, wherein the first shaping driving member 243 is located at the third edge side, the first shaping plate 244 is connected to the driving end of the first shaping driving member 243 and is parallel to the third edge, and the first shaping driving member 243 is used to drive the first shaping plate 244 to translate towards the first edge to push the battery piece on the magazine pad 100 to abut against the column located at the first edge. The second shaping unit 242 includes a second shaping driving member 245 and a second shaping plate 246, wherein the second shaping driving member 245 is located at the fourth edge side, the second shaping plate 246 is connected to the driving end of the second shaping driving member 245 and is parallel to the fourth edge, and the second shaping driving member 245 is used to drive the second shaping plate 246 to translate towards the second edge to push the battery piece on the magazine pad 100 to abut against the column located at the second edge.

[0087] During the receiving process, after the receiving mechanism 3 places a battery piece on the magazine pad 100 on the first supporting plate 221 and the second supporting plate 222, the first shaping driving member 243 first drives the first shaping plate 244 to press the battery piece against the column located at the first edge, and then the second shaping driving member 245 drives the second shaping plate 246 to press the battery piece against the column located at the second edge, thereby ensuring the shaping effect on the battery piece, and finally the first shaping plate 244 and the second shaping plate 246 are withdrawn. Of course, alternatively, the first shaping plate 244 can be driven first and then the second shaping plate 246 can be driven, which also achieves the shaping effect.

[0088] Alternatively, as shown in FIG. 6, the first shaping plate 244 is arranged at the third edge of the jacking through hole 21, and the second shaping plate 246 is arranged at the fourth edge of the jacking through hole 21. Figure 3 In this way, the first shaping plate 244 and the second shaping plate 246 can be arranged at the same jacking through hole 21, and the first shaping plate 244 and the second shaping plate 246 can be driven at the same time, thereby saving production cost.
