[0002] When the existing automatic sorting machine performs automatic sorting of photovoltaic battery cells, it mainly operates on a single-piece basis, that is, the single-piece photovoltaic battery cells conveyed by the belt line are picked up by the manipulator suction cups and placed into the corresponding material boxes one by one. This method has the disadvantages of low efficiency, large floor space of the machine, complex structure, and high cost. In order to accommodate more material boxes, the structural dimensions must be made larger and larger, which will greatly occupy the valuable factory space of customers. Summary of the Invention

The material boxes are arranged in multiple columns at intervals along the transmission direction of the transmission device. The handling devices are arranged in multiple groups at intervals along the transmission direction of the transmission device. Each group of the handling devices corresponds to one column of the material boxes. Each group of the handling devices includes two suction cup assemblies for sucking the battery cells on the transmission device. Each suction cup assembly can independently move in the direction perpendicular to the transmission direction of the transmission device.

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] Referring to Figures 1 to 4 shown, the full-automatic sorting machine for double-piece battery wafers of the present invention includes a frame 1, a workbench surface 2 provided on the frame 1, a material box 3 for placing battery wafers, a controller, a transmission device 4 and a handling device 5. The transmission device 4 and the handling device 5 are both electrically connected to the controller.

[0025] The material box 3 is placed on the workbench surface 2. Along the transmission direction of the transmission device 4, multiple columns of material boxes 3 are arranged at intervals. Along the direction parallel to the transmission direction of the transmission device 4, multiple rows of material boxes 3 are arranged at intervals. Battery wafers of different grades are respectively arranged in different material boxes 3, that is, each material box 3 corresponds to one grade of battery wafers. The grades described here include the efficiency grade or color grade of the battery wafers, etc.

[0026] The transmission device 4 is provided on the frame 1 and is used for transmitting the tested battery wafers. Two sets of transmission devices 4 are provided, and the two sets of transmission devices 4 are arranged in parallel. The two sets of transmission devices 4 are respectively the first transmission device 41 and the second transmission device 42. The material boxes 3 are respectively arranged outside the two sets of transmission devices 4 and are respectively located on both sides of the two sets of transmission devices 4.

[0027] The handling device 5 is located above the workbench surface 2 and is provided on the frame 1 above the workbench surface 2. Multiple groups of handling devices 5 are arranged at intervals along the transmission direction of the transmission device 4, and each group of handling devices 5 corresponds to a column of material boxes 3.

[0028] Each handling device 5 includes two suction cup assemblies, namely a first suction cup assembly 51 and a second suction cup assembly 52. Each suction cup assembly can move independently in a direction perpendicular to the conveying direction of the conveying device 4. The two suction cup assemblies located at the same column position can both move above the two groups of conveying devices 4 to suck the battery wafers on the conveying devices 4. Moreover, the two suction cup assemblies located at the same column position can both move above any one of the cassettes 3 located at the same column position as the suction cup assemblies to place the battery wafers on the two groups of conveying devices 4 into the cassette 3 at the relative position of the suction cup assemblies.

[0029] In this embodiment, each group of handling devices 5 includes two handling mechanisms. Each handling mechanism has one of the above-mentioned suction cup assemblies, and each handling mechanism further includes a driving mechanism 53 for driving the suction cup assembly to move. Specifically, the driving mechanism 53 can adopt an electric cylinder, and the two electric cylinders located at the same column position are arranged back to back on the frame 1.

[0030] The sorting machine further includes a track-changing mechanism. Through the track-changing mechanism, the battery wafers on the two groups of conveying devices 4 can be exchanged in position, that is, the battery wafers on the first conveying device 41 are transferred to the second conveying device 42, and the battery wafers on the second conveying device 42 are transferred to the first conveying device 41. The track-changing mechanism can adopt the structure in the prior art, such as using a manipulator. The manipulator grabs the battery wafers on the two groups of conveying devices 4 respectively and then rotates 180 degrees and then places the battery wafers on the two groups of conveying devices 4 respectively; or using a lifting mechanism. The lifting mechanism simultaneously lifts the battery wafers on the two groups of conveying devices 4, rotates 180 degrees and then descends, and places the two battery wafers on the two groups of conveying devices 4 respectively.

[0031] The sorting machine further includes an anti-collision mechanism for preventing the two suction cup assemblies at the same column position from colliding.

[0032] The anti-collision mechanism includes a sensor 61 for emitting an induction signal and an induction element 62 for receiving the induction signal. The sensor 61 is arranged on one of the two suction cup assemblies at the same column position, that is, the first suction cup assembly 51, and the induction element 62 is arranged on the other suction cup assembly at the same column position, that is, the second suction cup assembly 52. During the operation of the sorting machine, when the induction element 62 senses the induction signal emitted by the sensor 61 during the movement of the two suction cup assemblies, the controller controls the two electric cylinders to stop driving the two suction cup assemblies to move.

[0033] The anti-collision mechanism further includes protective blocks (not shown in the figure) respectively arranged on the two suction cup assemblies. The protective blocks are respectively located on the surfaces where the two suction cup assemblies come into contact during collision, and the protective blocks are made of soft materials. In this way, when the controller controls the two electric cylinders to stop driving the two suction cup assemblies to move, due to inertia, the two suction cup assemblies will still generate a certain displacement. At this time, even if the two suction cup assemblies collide, since the protective blocks on the two suction cup assemblies are in direct contact, the impact generated by the collision of the two suction cup assemblies can be reduced.

[0034] The sorting machine further includes a cartridge transfer device (not shown in the figure). Through the cartridge transfer device, the empty cartridge 3 can be transferred to the designated position of the sorting machine, and the cartridge 3 filled with solar cells can be transferred out of the sorting machine. The controller is electrically connected to the cartridge transfer device. The cartridge transfer device can adopt the structure in the prior art.

[0035] The working principle of the sorting machine is specifically introduced as follows:

[0036] After the performance grade data of the solar cells is tested, it is transmitted to the controller. The controller controls the two groups of transfer devices 4 to start synchronously and transfer two solar cells forward at the same time. The controller is set with the set position for the transfer of the transfer device 4, and this set position corresponds to the position of each column of cartridges 3.

[0037] When the two solar cells are transferred to the set position according to their grades, the controller controls the handling device 5 at the same column position as this set position to act, that is, the controller controls the electric cylinder to drive the two suction cup assemblies to move in the direction perpendicular to the solar cell transfer direction to be directly above the two groups of transfer devices 4 respectively. The controller controls the vacuum of the first suction cup assembly 51 and the second suction cup assembly 52 to be turned on, and adsorbs and fixes the two solar cells to the first suction cup assembly 51 and the second suction cup assembly 52 respectively. The first suction cup assembly 51 and the second suction cup assembly 52 move again in the direction perpendicular to the transfer direction of the transfer device 4 to be directly above the cartridge 3. The controller controls the vacuum of the first suction cup assembly 51 and the second suction cup assembly 52 to be turned off, so as to place the solar cells into the cartridge 3. During this process, the first suction cup assembly 51 and the second suction cup assembly 52 can act synchronously or asynchronously. The solar cells sucked by the first suction cup assembly 51 and the second suction cup assembly 52 can be placed in the same cartridge 3 in this column or in different cartridges 3.

[0038] In the above process, after the first suction cup assembly 51 sucks the battery cells on the first transfer device 41 and the second suction cup assembly 52 sucks the battery cells on the second transfer device 42, the first suction cup assembly 51 and the second suction cup assembly 52 can move outwardly from the two transfer devices 4 respectively, that is, the moving directions of the first suction cup assembly 51 and the second suction cup assembly 52 are opposite, so as to place the battery cells on the first transfer device 41 into the magazine 3 on the adjacent side, and place the battery cells on the second transfer device 42 into the magazine 3 on the adjacent side, that is, the battery cells on the two transfer devices 4 are respectively placed in the magazines 3 on both sides of the two transfer devices 4.

[0039] Alternatively, after the first suction cup assembly 51 sucks the battery cells on the first transfer device 41 and the second suction cup assembly 52 sucks the battery cells on the second transfer device 42, the first suction cup assembly 51 and the second suction cup assembly 52 both move to the same side of the two transfer devices 4, that is, the moving directions of the first suction cup assembly 51 and the second suction cup assembly 52 are the same. At this time, the battery cells on the first transfer device 41 and the battery cells on the second transfer device 42 can be placed into the magazine 3 located on the same side of the two transfer devices 4.

[0040] When it is necessary to place the battery cells on the first transfer device 41 into the magazine 3 on the side adjacent to the second transfer device 42, and at the same time place the battery cells on the second transfer device 42 into the magazine 3 on the side adjacent to the first transfer device 41, it is necessary to first exchange the positions of the battery cells on the first transfer device 41 and the second transfer device 42 through the track changing mechanism, and then after the first suction cup assembly 51 sucks the battery cells on the first transfer device 41 and the second suction cup assembly 52 sucks the battery cells on the second transfer device 42, the first suction cup assembly 51 and the second suction cup assembly 52 can move outwardly from the two transfer devices 4 respectively.

[0041] That is, the battery cells on each transfer device 4 can be transported to any magazine 3 at the same column position through the suction cup assembly. A fixed number of battery cells are placed in each magazine 3. When the number of battery cells placed in a magazine 3 reaches the set value, it means that the magazine 3 is full. The full magazine 3 is taken away through the magazine transfer device, and an empty magazine 3 is transported to the vacated position.

[0042] In this way, the sorting operation of the battery cells is completed. This sorter can simultaneously sort two battery cells at a time, which can improve the efficiency, thereby enhancing the production capacity of the battery cell manufacturing, and this sorter can effectively compress the structural size, thereby saving the floor space and cost, and improving the competitiveness of this product.

Specifically, the driving mechanism 54 is a double-slider linear motor module provided on the frame 1. The rest is the same as that in Embodiment 1 and will not be elaborated here.
