[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figure 1 and Figure 2As shown, the embodiment of the utility model provides a battery cell sorting device, which includes a sorting platform 10, a testing mechanism 30, a robotic arm 40, an identification member 50 and a battery cell transfer control member. The sorting platform 10 has a loading tray placement position 11, a battery cell detection position 12 and a lowering tray placement position 13. In an optional embodiment, a plurality of lowering tray placement positions can be provided to provide capacity. The loading tray placement position 11 and the lowering tray placement position 13 are both used to place a plurality of stacked battery cell placement trays 20. The testing mechanism 30 The robot 40 is arranged on the battery cell detection position 12, and has a transfer part 41. The transfer part 41 can transfer the battery cells between the upper tray placement position 11, the testing mechanism 30 and the lower tray placement position 13. The identification part 50 is arranged on the robot 40, and the identification part 50 can identify the battery cells in the uppermost battery tray 20 located at the upper tray placement position 11. The battery cell transfer control part is respectively connected with the signal of the identification part 50 and the robot 40, and the battery cell transfer control part controls the operation of the robot 40 according to the recognition result of the identification part 50.

[0028] In applying the battery cell sorting equipment provided in this embodiment, the transfer part 41 of the robot arm 40 is first moved to above the upper tray placement position, and the identification part 50 is used to detect the arrangement and height of the batteries in the uppermost battery cell placement tray 20 of the upper tray placement position 11, and the height and horizontal grasping position of the transfer part 41 are obtained. The transfer part 41 descends and grasps the batteries. The transfer part 41 carries the batteries to the battery cell detection position 12 and places the batteries on the testing mechanism 30. After the testing mechanism 30 detects the voltage and internal resistance of the batteries, the transfer part 41 grasps the detected batteries. The transfer part 41 moves to above the corresponding lower tray placement position 13 according to the measurement results of the voltage and internal resistance of the batteries. The identification part 50 is used to detect the arrangement and height of the batteries in the uppermost battery cell placement tray 20 of the lower tray placement position 13, and the height and horizontal placement position of the transfer part 41 are obtained. The transfer part 41 descends and places the batteries, thereby reducing the workload of battery cell sorting and improving the work efficiency of battery cell sorting.

[0029] The robot arm 40 may be an industrial robot or a collaborative robot.

[0030] Specifically, the identification part 50 is used to detect the height of the cells in the topmost cell placement tray 20 at the upper tray placement position 11 or the lower tray placement position 13, and the height to which the transfer part 41 descends is obtained. There is no need to set a lifting mechanism for lifting the cell placement tray 20, thereby reducing the size of the sorting platform 10 and reducing the cost of the cell sorting equipment.

[0031] In this embodiment, the identification component 50 is connected to the test mechanism 30 by signal. The identification component 50 can also identify the code of the battery cell grasped by the transfer part 41 and record the code. The identification component 50 sends the identified code to the test mechanism 30. After the test mechanism 30 tests the battery cell, the test mechanism 30 records the battery cell code and the corresponding test results.

[0032] In this embodiment, the identification element 50 is a camera. In other embodiments, the identification element 50 includes a camera and a laser ranging element.

[0033] like Figure 1 and Figure 2 As shown, the sorting platform 10 also has an empty tray transfer position 14, which is used to place multiple stacked battery cell placement trays 20. If the topmost battery cell placement tray 20 of the upper tray placement position 11 has no battery cells, the battery cell placement tray 20 without battery cells is transferred to the topmost layer of the empty tray transfer position 14; if the topmost battery cell placement tray 20 of the lower tray placement position 13 is full of battery cells, the topmost battery cell placement tray 20 of the empty tray transfer position 14 is transferred to the topmost layer of the lower tray placement position 13.

[0034] In the present embodiment, the battery cell sorting equipment further includes a tray transfer control component, which is signal-connected to the identification component 50 and the robotic arm 40, respectively. The tray transfer control component controls the robotic arm 40 to work according to the recognition result of the identification component 50, so as to transfer the battery cell placement tray 20 between the upper tray placement position 11, the empty tray transfer position 14, and the plurality of lower tray placement positions 13. If the identification component 50 detects that there are no batteries in the uppermost battery cell placement tray 20 at the upper tray placement position 11, the robotic arm 40 transfers the uppermost battery cell placement tray 20 at the upper tray placement position 11 to the uppermost layer of the empty tray transfer position 14; if the identification component 50 detects that the uppermost battery cell placement tray 20 at the lower tray placement position 13 is full of batteries, the robotic arm 40 transfers the uppermost battery cell placement tray 20 at the empty tray transfer position 14 to the uppermost layer of the lower tray placement position 13.

[0036] like Figure 1As shown, the sorting platform 10 includes a base 15, a loading carrier 16 and a unloading carrier 17. The loading carrier 16, the unloading carrier 17 and the battery cell detection position 12 are arranged at intervals on the base 15. The loading carrier 16 and the unloading carrier 17 are detachably arranged on the base 15. The loading tray placement position 11 is arranged on the loading carrier 16, and the unloading tray placement position 13 is arranged on the unloading carrier 17. The battery cell placement tray 20 has a receiving groove for placing the battery cell. The receiving grooves of the battery cell placement tray 20 corresponding to batteries of different sizes are of different sizes, and the models of the loading carrier 16 and the unloading carrier 17 corresponding to batteries of different sizes are different. By replacing the loading carrier 16 and the unloading carrier 17 of different models, the battery cell sorting equipment can be quickly changed.

[0037] like Figure 1 and Figure 2 As shown, the loading carrier 16 includes a loading stop plate 161, and the unloading carrier 17 includes a unloading stop plate 171. The loading stop plate 161 is provided with a first pin hole 1611 at the corner, and the unloading stop plate 171 is provided with a second pin hole 1711 at the corner. The sorting platform 10 includes a first mounting pin and a second mounting pin. The first mounting pin is detachably provided through the first pin hole 1611 and the base 15, and the second mounting pin is detachably provided through the second pin hole 1711 and the base 15. Since the first mounting pin is detachably provided through the first pin hole 1611 and the base 15, and the second mounting pin is detachably provided through the second pin hole 1711 and the base 15, the loading carrier 16 and the unloading carrier 17 are easy to disassemble and assemble, and the structure is simple and the cost is low.

[0038] In this embodiment, the loading carrier 16 has a loading adjustment member for adjusting the accommodation size of the loading tray placement position 11, and the unloading carrier 17 has a unloading adjustment member for adjusting the accommodation size of the unloading tray placement position 13. The battery cell placement tray 20 has an accommodation groove for placing the battery cells. The accommodation grooves of the battery cell placement tray 20 corresponding to batteries of different sizes have different sizes, and the loading carrier 16 and the unloading carrier 17 corresponding to batteries of different sizes have different models. The unloading adjustment member adjusts the accommodation size of the unloading tray placement position 13 to complete the rapid changeover of the battery cell sorting equipment.

[0039] Specifically, the loading adjustment member includes two first sliders arranged opposite to each other and two second sliders arranged opposite to each other, the two first sliders and the two second sliders are arranged to form a loading tray placement position 11, the facing directions of the two first sliders are perpendicular to the facing directions of the two second sliders, and the accommodation size of the loading tray placement position 11 is adjusted by adjusting the spacing between the two first sliders and the spacing between the two second sliders, and the unloading adjustment member includes two third sliders arranged opposite to each other and two fourth sliders arranged opposite to each other, the two third sliders and the two fourth sliders are arranged to form a unloading tray placement position 13, the facing directions of the two third sliders are perpendicular to the facing directions of the two fourth sliders, and the accommodation size of the unloading tray placement position 13 is adjusted by adjusting the spacing between the two third sliders and the spacing between the two fourth sliders.

[0040] like Figure 1 As shown, the multiple unloading tray placement positions 13 include a waste position 131 and multiple unloading gears 132, and the multiple unloading gears 132 are respectively used to place trays carrying batteries of different gears. The testing mechanism 30 measures the voltage and internal resistance of the battery cell, and grades the battery cell according to the measurement results of the voltage and internal resistance of the battery cell. The transfer unit 41 transfers the battery cell to the top tray of the waste position 131 or the top tray of the unloading gear 132 of the corresponding gear according to the measurement results of the voltage and internal resistance of the battery cell. If the measurement results of the voltage and internal resistance of the battery cell show that the battery cell is unqualified, the battery cell is transferred to the waste position 131. The transfer unit 41 transfers the battery cell to the top tray of the waste position 131 or the top tray of the unloading gear 132 of the corresponding gear according to the measurement results of the voltage and internal resistance of the battery cell to avoid mixing of battery cell sorting.

[0041] like Figure 1 As shown, the testing mechanism 30 has a battery cell limiting portion 31 and a limiting adjustment member for adjusting the limiting size of the battery cell limiting portion 31. The limiting size of the battery cell limiting portion 31 is adjusted by the limiting adjustment member to meet the limiting requirements of battery cells of different sizes. Specifically, the battery cell limiting portion 31 includes two first limiting sliders arranged opposite to each other and two second limiting sliders arranged opposite to each other, the two first limiting sliders and the two second limiting sliders are arranged to form a battery cell accommodating space, the facing directions of the two first limiting sliders are perpendicular to the facing directions of the two second limiting sliders, and the limiting adjustment member is drivingly connected to the first limiting slider and the second limiting slider to adjust the spacing between the two first limiting sliders and the spacing between the two second limiting sliders.

[0042] like Figure 1As shown, the transfer unit 41 includes a suction cup to be detected 411 and a suction cup after detection 412 arranged in parallel, the suction cup to be detected 411 transfers the battery cell between the upper material tray placement position 11 and the battery cell detection position 12, and the suction cup after detection 412 transfers the battery cell between the battery cell detection position 12 and multiple unloading tray placement positions 13. The use of the suction cup to be detected 411 and the suction cup after detection 412 arranged in parallel can improve the transfer efficiency of the transfer unit 41 in transferring the battery cell between the upper material tray placement position 11, the battery cell detection position 12 and the unloading tray placement position 13.

[0043] Specifically, the transfer unit 41 uses the suction cup 411 to be inspected to suck up the battery cells from the topmost tray of the loading tray at the loading tray placement position. After the transfer unit 41 carries the battery cells to the battery cell inspection position 12, the transfer unit 41 descends and uses the post-inspection suction cup 412 to take out the battery cells that have been inspected on the testing mechanism 30, and then uses the suction cup 411 to be inspected to place the carried battery cells on the testing mechanism 30.
