[0034] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the description.

[0035] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0037] According to an embodiment of the present application, a rotary jaw device 1 is provided. As Figures 1 to 4 shown, the rotary jaw device 1 includes a mounting seat 14 and a plurality of first material taking mechanisms 11. The plurality of first material taking mechanisms 11 are rotatably connected to the mounting seat 14, and the plurality of first material taking mechanisms 11 can rotate about a first axis. Wherein, each first material taking mechanism 11 includes two adsorbing members 111 arranged at intervals in the horizontal direction, so that each first material taking mechanism 11 can adsorb two workpieces 100.

[0038] In this example, the rotary gripper device 1 has a plurality of first material taking mechanisms 11. The plurality of first material taking mechanisms 11 are rotatably connected to the mounting base 14. Two suction attachments 111 are provided on each first material taking mechanism 11, so that the workpiece 100 can be transported to each process, and multiple workpieces 100 can be transported simultaneously to improve the processing efficiency.

[0039] For example, as Figure 1 shown, a feeding mechanism 2, a return transfer mechanism 4, a screen printing and dispensing mechanism 3, and a first waste collection mechanism 5 are provided at intervals along the circumferential direction of the rotary gripper device 1. The first material taking mechanism 11 is rotatably arranged on the mounting base 14, and the suction attachment 111 can transport the workpiece 100 between each process.

[0040] As Figure 4 shown, in this example, the workpieces 100 are grouped in twos. One of the two workpieces 100 is face up and the other is face down. Two suction attachments 111 are respectively provided on each first material taking mechanism 11, so that one first material taking mechanism 11 can transport a group of workpieces 100 at a time.

[0041] In this example, the workpiece 100 can be a battery cell. The screen printing and dispensing mechanism 3 can print glue on the surface of the battery cell, so that the welding tape glue can be bonded to the surface of the battery cell, so as to facilitate welding the welding tape to the surface of the battery cell.

[0042] In one example, as Figures 1 to 3 shown, four first material taking mechanisms 11 are provided.

[0043] As Figure 1 and Figure 2 shown, the four first material taking mechanisms 11 are arranged at intervals along the circumferential direction of the rotating shaft 15. When each first material taking mechanism 11 rotates to the feeding mechanism 2, the screen printing and dispensing mechanism 3, the return transfer mechanism 4, and the first waste collection mechanism 5, it can choose whether to put down or adsorb the workpiece 100. By providing four first material taking mechanisms 11 on the rotary gripper device 1, the transfer efficiency can be improved and the transfer process can be kept at a low value.

[0044] In one example, as Figures 1 to 3 shown, the angle between every two adjacent first material taking mechanisms 11 is equal.

[0045] As Figure 1 and Figure 3 shown, in this example, a plurality of first material taking mechanisms 11 are provided, and the angle between every two adjacent first material taking mechanisms 11 is equal. For example, if four first material taking mechanisms 11 are provided, the angle between two adjacent first material taking mechanisms 11 is 90°.

[0046] As Figure 1As shown, in this example, the angles between the adjacent loading mechanism 2, screen printing and dispensing mechanism 3, return mechanism 4 and the first waste collection mechanism 5 are also 90°, so that every time the rotary gripper device 1 rotates, that is, every time it rotates 90°, each first material taking mechanism 11 can correspond to one of the loading mechanism 2, screen printing and dispensing mechanism 3, return mechanism 4 and the first waste collection mechanism 5.

[0047] In one example, as Figure 2 shown, the first material taking mechanism 11 further includes a first driving member 12, and the first driving member 12 is adapted to drive the two suction members 111 to move in the vertical direction.

[0048] As Figure 2 shown, in this example, the first material taking mechanism 11 further includes a plurality of first driving members 12, and the first driving member 12 is used to drive the suction member 111 to move in the vertical direction, that is, the first driving member 12 can drive the suction member 111 to move along the Z axis. After the suction member 111 adsorbs the workpiece 100 at the work station, the first driving member 12 can drive the suction member 111 to lift upward, so as to avoid other mechanisms when the first material taking mechanism 11 rotates. When the first material taking mechanism 11 rotates to the next work station, the first driving member 12 can drive the suction member 111 to move downward, so as to accurately place the workpiece 100 on the work station.

[0049] In one example, the first driving member 12 includes a cylinder, and the suction member 111 includes a negative pressure suction cup.

[0050] As Figure 2 shown, in this example, by adsorbing the surface of the workpiece 100 with the negative pressure suction cup, the stability of sucking the workpiece 100 can be ensured, and damage to the workpiece 100 can be reduced or avoided. The first driving member 12 is a cylinder, so that a common air pipe 13 can be shared with the negative pressure suction cup, which is beneficial to simplifying the structure of the rotary gripper device 1. Moreover, the cylinder drives the suction member 111 to move, having relatively high control accuracy and driving speed. Among them, the air pipe 13 can be fixed on the mounting seat 14, and can provide air power for a plurality of cylinders and negative pressure suction cups.

[0051] In this example, two negative pressure suction cups can be provided, and the two negative pressure suction cups are connected to the piston rod of the cylinder through a bracket. Each negative pressure suction cup can include a plurality of negative pressure nozzles, and the workpiece 100 is adsorbed through the plurality of negative pressure nozzles.

[0052] Of course, the first driving member 12 can also be other types of driving structures, such as a linear cylinder, etc., which can be determined by those skilled in the art according to the actual situation and will not be specifically limited here.

[0053] In one example, as Figure 2As shown, the rotary gripper device 1 further includes a connecting member 16, the connecting member 16 is rotatably connected to the mounting base 14, the connecting member 16 is provided with a plurality of mounting portions 161 along the circumferential direction, and each of the first material taking mechanisms 11 is mounted on one of the mounting portions 161.

[0054] In this example, the connecting member 16 is rotatably connected to the mounting base 14, the connecting member 16 is provided with a plurality of mounting portions 161 at intervals along the circumferential direction, and the first material taking mechanism 11 is mounted on one mounting portion 161, so as to facilitate the disassembly or installation of the first material taking mechanism 11, thereby facilitating the replacement or repair of the first material taking mechanism 11. For example, the mounting portion 161 is a mounting plate, and the first driving member 12 can be screwed to the mounting plate through a fastener.

[0055] In one example, the rotary gripper device 1 further includes a second driving member, and the second driving member is adapted to drive the connecting member 16 to rotate.

[0056] In this example, the second driving member can drive the connecting member 16 to rotate, thereby driving a plurality of first material taking mechanisms 11 to rotate. For example, the second driving member can be a rotary motor, and the connecting member 16 is in transmission connection with the rotating shaft 15. The rotary motor can drive the rotating shaft 15 to rotate, thereby driving the connecting member 16 to rotate. Of course, the second driving member can also be other types of rotary driving devices, which can be determined by those skilled in the art according to the actual situation, and are not specifically limited herein.

[0057] In one example, the second driving member and the connecting member 16 are in transmission connection through a speed reducer. For example, the second driving member is a motor, and the motor is in transmission connection with the connecting member 16 through a speed reducer, so as to be able to adjust the rotation speed of driving the connecting member 16, increase the output torque of the motor, and increase the stability of driving the connecting member 16 to rotate.

[0058] According to another embodiment of the present application, a battery string welding machine is provided, as Figures 1 to 4 shown, the battery string welding machine includes the rotary gripper device 1 of the above embodiment, and the battery string welding machine further includes:

[0059] A feeding mechanism 2, adapted to feed the workpiece 100;

[0060] A screen printing and dispensing mechanism 3, adapted to perform glue printing on the workpiece 100;

[0061] A return mechanism 4, adapted to return the workpiece 100 with single-sided glue printing on the screen printing and dispensing mechanism 3;

[0062] A first waste collection mechanism 5, adapted to collect the discarded workpiece 100;

[0063] Among them, the feeding mechanism 2, the screen printing and dispensing mechanism 3, the return mechanism 4, and the first waste collection mechanism 5 are arranged at intervals around the first axis, and the rotary gripper device 1 can transfer the workpiece 100 between the feeding mechanism 2, the screen printing and dispensing mechanism 3, the return mechanism 4, and the first waste collection mechanism 5.

[0064] As Figures 1 to 4 shown, in this example, the feeding mechanism 2, the screen printing and dispensing mechanism 3, the return mechanism 4, and the first waste collection mechanism 5 are arranged around the first axis. The rotary gripper device 1 is provided with a plurality of first material taking mechanisms 11. Through the plurality of first material taking mechanisms 11, the workpiece 100 can be transferred between the feeding mechanism 2, the screen printing and dispensing mechanism 3, the return mechanism 4, and the first waste collection mechanism 5, so that the rotary gripper device of the present application can reduce the transfer process of the workpiece 100, thereby improving the processing efficiency.

[0065] In this example, the feeding mechanism 2 is used for feeding the workpiece 100, that is, the feeding mechanism 2 can convey the workpiece 100 to one side close to the rotary gripper device 1, so as to facilitate the first material taking mechanism 11 to adsorb the workpiece 100 of the feeding mechanism 2. Then, the first material taking mechanism 11 can transfer the workpiece 100 to the screen printing and dispensing mechanism 3, and the screen printing and dispensing mechanism 3 can print glue on the surface of the workpiece 100. When only one side of the workpiece 100 is printed with glue, the workpiece 100 is returned through the return mechanism 4, and the first material taking mechanism 11 can transfer the workpiece 100 on the return mechanism 4 to the screen printing and dispensing mechanism 3, so that the screen printing and dispensing mechanism 3 can print glue on the other side of the workpiece 100. When the glue printing on the surface of the workpiece 100 is unqualified, for example, the position of the glue is not in the preset position and other situations, the first material taking mechanism 11 can transfer the unqualified workpiece 100 to the first waste collection mechanism 5 for recycling.

[0066] In this example, the return mechanism 4 is provided with a detection component, and the detection component can detect whether the glue printed on the surface of the workpiece 100 is in the preset position. When the detection is unqualified, the first material taking mechanism 11 directly transfers the workpiece 100 to the first waste collection mechanism 5. For example, the surface of the workpiece 100 can be photographed by a CCD camera (a digital camera that uses a charge-coupled device (CCD for short) as an image sensor), and then the screen printing and dispensing on the surface of the workpiece 100 can be determined to be qualified through program analysis, so as to improve the yield of the final product. Of course, other detection methods can also be used, and those skilled in the art can determine according to the actual situation, and no specific limitation is made here.

[0067] In this example, the first waste collection mechanism 5 can be a waste box, or it can also be a waste collection platform and other structures. Regarding the specific structure of the first waste collection mechanism 5, those skilled in the art can determine according to the actual situation, and no specific limitation is made here.

[0068] In an example, Figure 1 As shown, along the rotation direction of the first material taking mechanism 11, the feeding mechanism 2, the return mechanism 4, the screen printing and dispensing mechanism 3 and the first waste collecting mechanism 5 are arranged in sequence.

[0069] like Figure 1 As shown, in this example, the first material taking mechanism 11 can rotate in a clockwise direction. That is, in a clockwise direction, the feeding mechanism 2, the return mechanism 4, the screen printing and dispensing mechanism 3 and the first waste material collecting mechanism 5 are arranged in sequence. Figure 1 As shown, the first clamping position 11-1 can clamp the workpiece 100 of the feeding mechanism 2, the second clamping position 11-2 can clamp the workpiece 100 of the return mechanism 4, the third clamping position 11-3 can place the workpiece 100 in the screen printing dispensing mechanism 3, and the fourth clamping position 11-4 can place the waste workpiece 100 in the first waste collection mechanism 5. The rotating jaw device 1 is correspondingly provided with four first material taking mechanisms 11. When the four first material taking mechanisms 11 transport the workpieces 100 on each mechanism, the waste of processes can be avoided as much as possible, which is conducive to saving processes and improving the transport efficiency.

[0070] like Figure 1 As shown, the feeding mechanism 2 includes a first correcting component 21, which can drive the workpiece 100 to move along the first direction and / or the second direction, and the fixture can transfer the workpiece 100 on the first correcting component 21 to the silk screen dispensing mechanism 3.

[0071] The first deviation-correcting assembly 21 can adjust the position of the workpiece 100 so that the workpiece 100 can reach a preset position, so that when the rotating jaw device 1 transfers the workpiece 100 from the feeding mechanism 2 to the screen printing and dispensing mechanism 3, it can also print glue on the surface of the workpiece 100 at the preset position of the screen printing and dispensing mechanism 3.

[0072] In this example, the workpiece 100 is fixedly placed on the first deflection correcting assembly 21, and the first deflection correcting assembly 21 can drive the workpiece 100 along the first direction, and the first deflection correcting assembly 21 can also drive the workpiece 100 to move along the second direction until the workpiece 100 is adjusted to a preset position. The first material picking mechanism 11 can absorb the workpiece 100 from the first deflection correcting assembly 21.

[0073] Among them, Figure 1 As shown, the first direction may be the x-axis direction, and the second direction may be the y-axis direction.

[0074] In this example, the first rectification component 21 includes a fixed table, a first sliding table, and a second sliding table. The first sliding table is slidably connected to the fixed table in a first direction, and the second sliding table is slidably connected to the first sliding table in a second direction. The workpiece 100 is fixedly arranged on the second sliding table. By sliding the first sliding table and the second sliding table, the position of the workpiece 100 in the first direction and the second direction can be adjusted.

[0075] Wherein, the first rectification component 21 further includes a CCD camera. The workpiece 100 is photographed by the CCD camera, and the position of the workpiece 100 can be analyzed through a program, so as to control the movement of the first sliding table and the second sliding table to automatically adjust the position of the workpiece 100.

[0076] In this example, the first sliding table and the second sliding table can be driven to move by an air cylinder, or can also be driven to move by a motor lead screw structure. Those skilled in the art can determine according to the actual situation and are not specifically limited herein.

[0077] In an example, as Figure 1 shown, the loading mechanism 2 further includes a first track 22. The first rectification component 21 is slidably connected to the first track 22, and the first rectification component 21 can slide along the first track 22.

[0078] As Figure 1 shown, in this example, one side of the first track 22 facing the rotary gripper device 1 is the material taking position, and the first material taking mechanism 11 can adsorb the workpiece 100 at the material taking position. One side of the first track 22 away from the rotary gripper device 1 is the loading position, and loading can be performed by a manipulator or manually. The first rectification component 21 is slidably connected to the first track 22. For example, the first track 22 is arranged along the y-axis, the first sliding table of the first rectification component 21 is slidably connected to the first track 22, and the second sliding table is slidably connected to the first sliding table in the x direction. The first sliding table can move along the first track 22 to the loading position. The workpiece 100 is fixed on the second sliding table of the first rectification component 21 by a manipulator or manually, and then the first track 22 drives the first rectification component 21 to move to the material taking position. The first rectification component 21 adjusts the workpiece 100 to a preset position, and then the first material taking mechanism 11 adsorbs the workpiece 100 for transportation.

[0079] In this example, the first rectification component 21 can also be conveyed by a conveyor belt. For example, the conveyor belt is arranged along the y-axis, the first sliding table is fixedly connected to the conveyor belt, and the conveyor belt can drive the first sliding table to move along the y-axis. The second sliding table is slidably connected to the first sliding table in the x direction.

[0080] In an example, as Figure 1 and Figure 4As shown, the return mechanism 4 further includes a second deviation rectifying component 41. The second deviation rectifying component 41 can drive the workpiece 100 to move along the first direction and / or the second direction. The first material taking mechanism 11 can transfer the workpiece 100 on the second deviation rectifying component 41 to the screen printing and dispensing mechanism 3 or the first waste collection mechanism 5.

[0081] As Figure 4 shown, in this example, the first conveyor belt 42 of the return mechanism 4 can convey the workpiece 100 with only one-sided printing and dispensing back to the second deviation rectifying component 41. After the workpiece 100 adjusts its position along the first direction and the second direction through the second deviation rectifying component 41 and is detected by the detection device at the position of the second deviation rectifying component 41, if the printing and dispensing on the surface of the workpiece 100 is qualified, it is then transferred to the screen printing and dispensing mechanism 3 by the first material taking mechanism 11 to perform printing and dispensing on the other side of the workpiece 100. Or, after being detected by the detection device, if the printing and dispensing on the surface of the workpiece 100 is unqualified, the first material taking mechanism 11 can transfer the workpiece 100 to the first waste collection mechanism 5.

[0082] Among them, the structure of the second deviation rectifying component 41 and the process of adjusting the position of the workpiece 100 are similar to those of the first deviation rectifying component 21. For example, the second deviation rectifying component 41 includes a slide rail arranged along the y-axis direction, and a third sliding table and a fourth sliding table. The third sliding table is slidably arranged on the slide rail, and the fourth sliding table is movably arranged along the x direction on the third sliding table. The workpiece 100 can be fixed on the fourth sliding table. The first material taking mechanism 11 can take the workpiece 100 from the fourth sliding table.

[0083] In this example, a flipping component 43 is further arranged on the side of the first conveyor belt 42 facing the second deviation rectifying component 41. The workpiece 100 conveyed on the first conveyor belt 42 has the surface with printing and dispensing facing up, while the flipping component 43 can flip the workpiece 100 and transfer it to the second deviation rectifying component 41. That is, the flipping component 43 can flip the surface of the workpiece 100 with printing and dispensing to face down and the non-printed surface to face up. So that when the first material taking mechanism 11 transfers the workpiece 100 on the second deviation rectifying component 41 to the screen printing and dispensing mechanism 3, the non-printed surface of the workpiece 100 faces up, which is convenient for printing and dispensing on the non-printed surface of the workpiece 100.

[0084] As Figure 1 shown, in this example, the second deviation rectifying component 41 is provided with a glue avoiding tooling 44, and the workpiece 100 is placed on the glue avoiding tooling 44. The glue avoiding tooling 44 is fixedly installed at the upper end of the fourth sliding table. The flipping component 43 flips the workpiece 100 on the first conveyor belt 42 and transfers it to the glue avoiding tooling 44, and the surface of the workpiece 100 with screen printing and dispensing contacts the glue avoiding tooling 44, so as to avoid problems such as deformation or falling off caused by the screen printing and dispensing on the surface of the workpiece 100 contacting the second deviation rectifying component 41.

[0085] Among them, the glue avoidance tooling 44 is provided with a plurality of glue avoidance holes, and each glue avoidance hole can correspond to a silk screen dispensing point on the workpiece 100, so that each silk screen dispensing point on the surface of the workpiece 100 is located at the glue avoidance hole, and the silk screen dispensing point can be suspended and will not contact other components.

[0086] In one example, as Figure 4 shown, the battery string welder further includes a conveying mechanism 6. The conveying mechanism 6 is located on one side of the silk screen dispensing mechanism 3, and the rotary gripper device 1 is also arranged between the conveying mechanism 6 and the silk screen dispensing mechanism 3. The rotary gripper device 1 is suitable for transferring the workpiece 100 on the silk screen dispensing mechanism 3 to the conveying mechanism 6. The conveying mechanism 6 can convey the workpiece 100 with double-sided glue printing to the next process, such as the welding process. The workpiece 100 with single-sided glue printing can be transferred to the return mechanism 4 for return through the third transfer mechanism 9, that is, returned to the second rectifying component 41 through the first conveyor belt 42.

[0087] In this example, the conveying mechanism 6 can be a conveyor belt structure. The third transfer mechanism 9 can be a manipulator, or a vacuum chuck transfer structure, or the same as the rotary gripper device 1. The conveying mechanism 6 is provided with a detection device, which can detect whether the workpiece 100 on the conveyor belt has double-sided glue printing. If the workpiece 100 has double-sided glue printing, it is directly conveyed to the next process; if the workpiece 100 has single-sided glue printing, it is transferred to the first conveyor belt 42 through the third transfer mechanism 9. Among them, as Figure 4 shown, when transferring through the third transfer mechanism 9, the third transfer mechanism 9 can rotate the workpiece 100 counterclockwise by 90°, and then place it on the first conveyor belt 42. After subsequent conveyance by the flipping component 43 and the second rectifying component 41, the workpiece 100 can be in a suitable position when the rotary gripper device 1 transfers.

[0088] In this example, the conveying mechanism 6 further includes a detection component located on one side of the conveyor belt for detecting whether the workpiece 100 on the conveyor belt has double-sided glue printing. For example, the detection component can be a CCD camera. The surface of the workpiece 100 is photographed by the CCD camera, and then it is determined whether the surface of the workpiece 100 is printed with glue through program analysis. Of course, it can also be detected by other detection devices, which can be determined by those skilled in the art according to the actual situation and are not specifically limited here.

[0089] In one example, as Figure 4 shown, the battery string welder further includes a second waste collection mechanism 8, and the rotary gripper device can transfer the workpiece 100 between the silk screen dispensing mechanism 3, the conveying mechanism 6 and the second waste collection mechanism 8.

[0090] The screen printing and dispensing mechanism 3 is provided with a conveyor belt, which can drive the workpiece 100 to move. The equipment for screen printing and dispensing can apply glue to the upward surface of the workpiece 100. A detection device is arranged on one side of the conveyor belt. The detection device can detect whether the glue applied to the surface of the workpiece 100 is qualified. If the glue application is qualified, the rotating gripper device can transfer the workpiece 100 to the conveying mechanism 6; if the glue application is unqualified, the rotating gripper device can transfer the workpiece 100 to the second waste collection mechanism 8.

[0091] In this example, the cell string welder further includes a solder tape processing device, which can cover the solder tape on the cell with glue applied on the surface. The solder tape corresponds to the position of screen printing and dispensing, so that the solder tape can be adhered to the cell. A welding device, located on one side of the solder tape processing device, is adapted to weld the solder tape to the cell.
