[0030] Please refer to Figures 1 to 3, the present utility model proposes a swing arm mechanism 100, which is used for transporting workpieces to be transported. The swing arm mechanism 100 includes a frame assembly 1, a swing arm assembly 2 and a grasping assembly 3; the swing arm assembly 2 includes a body 21 and a connecting arm 22 connected to the body 21. The body 21 is rotatably installed on the frame assembly 1. The number of connecting arms 22 is at least three, and at least three connecting arms 22 are arranged at circumferential intervals along the central axis of the body 21; the number of grasping assemblies 3 is at least three, and the number of grasping assemblies 3 is equal to the number of connecting arms 22. Each connecting arm 22 is provided with a grasping assembly 3, and the grasping assembly 3 is used for grasping the parts to be transported. Specifically, when machining the body 21, a plurality of connecting arms 22 are integrally formed. At the same time, it can also be that a plurality of detachable connecting arms 22 are connected to the body 21. The detachable setting can adjust the number of connecting arms 22 according to different production lines, adjust the angle between the connecting arms 22 according to the layout of the production line, then rotatably install the body 21 on the frame assembly 1, and then install the grasping assembly 3 on the connecting arm 22, so that the assembly of the swing arm mechanism 100 is completed; taking three connecting arms 22 as an example, during production operations, the production line transports the raw materials to the position to be processed. The first connecting arm 22 in the swing arm assembly 2 is located at the position to be processed, the second connecting arm 22 is located at the processing position, and the third connecting arm 22 is located at the collection position. Then the grasping assembly 3 on the connecting arm 22 located at the position to be processed grasps the raw materials. At this time, the body 21 is driven to rotate until the first connecting arm 22 rotates above the processing position. At this time, the second connecting arm 22 rotates above the collection position, and the third connecting arm 22 rotates above the position to be processed. When the raw materials grasped by the grasping assembly 3 on the first connecting arm 22 are being processed at the processing position, the grasping assembly 3 on the third connecting arm 22 will grasp the raw materials at the position to be processed, and the grasping assembly 3 on the second connecting arm 22 will place the processed products on the collection position for collection. After the raw materials at the processing position are processed, the grasping assembly 3 on the first connecting arm 22 grasps the processed products, and then rotates again. The first connecting arm 22 rotates to the collection position, the grasping assembly 3 on the third connecting arm 22 transports the raw materials to the processing position, and the second connecting arm 22 will rotate to the position to be processed to wait for grasping the raw materials; in this way, during the processing process, the raw materials at the collection position do not need to wait for the processing time of the previous raw materials and the time for placing and collecting. After the previous raw materials are processed and transported to the collection position, the next raw materials will be transported to the processing position, which greatly shortens the waiting time of the raw materials and improves the transportation efficiency of the swing arm mechanism 100, thereby improving the production efficiency of the battery wafers.

[0031] Please refer to Figure 1 and Figure 2, in one embodiment, the number of connecting arms 22 is four, and the four connecting arms 22 are arranged at circumferential intervals along the central axis of the body 21. By setting the number of connecting arms 22 to four and arranging the four connecting arms 22 at circumferential intervals along the central axis of the body 21, the angle between two adjacent connecting arms 22 is 90°. The positions to be processed, processing positions, inspection positions, and collection positions on the production line are distributed in a directional manner. Specifically, during production operations, the production line transports raw materials to the position to be processed. The first connecting arm 22 is located at the position to be processed, the second connecting arm 22 is located at the processing position, the third connecting arm 22 is located at the inspection position, and the fourth connecting arm 22 is located at the collection position. Then, the gripping component 3 on the connecting arm 22 located at the position to be processed grabs the raw materials. At this time, the body 21 is driven to rotate until the first connecting arm 22 rotates above the processing position. At this time, the second connecting arm 22 rotates above the inspection position, the third connecting arm 22 rotates above the collection position, and the fourth connecting arm 22 will rotate above the position to be processed. When the raw materials grabbed by the gripping component 3 on the first connecting arm 22 are being processed at the processing position, the gripping component 3 on the fourth connecting arm 22 will grab the raw materials at the position to be processed, and the gripping component 3 on the third connecting arm 22 will place the processed products on the collection position for collection. After the raw materials at the processing position are processed, the gripping component 3 on the first connecting arm 22 grabs the processed products and then rotates again. The first connecting arm 22 rotates to the inspection position, the gripping component 3 on the fourth connecting arm 22 transports the raw materials to the processing position, the third connecting arm 22 rotates to the collection position, and the second position to be processed waits to grab the raw materials. In this way, during the processing process, the raw materials at the collection position do not need to wait for the processing time of the previous raw material, the waiting time after processing is completed, and the time for placing and collecting the products. After the previous raw material is processed and during the transportation to the inspection position, the next raw material will be transported to the processing position. This significantly shortens the waiting time of the raw materials and improves the transportation efficiency of the swing arm mechanism 100, thereby improving the production efficiency of the battery wafers.

[0032] Furthermore, according to the layout of different production lines, the number of connecting arms 22 can be set to ensure that when the processed products are transported to the next process, the next raw material will be transported to the processing position for processing, preventing processing waiting time.

[0033] Please refer to Figure 1 and Figure 3, in one embodiment, the grasping assembly 3 includes a suction cup member 31. One side of the suction cup member 31 is used to connect with the connecting arm 22, and the other side of the suction cup member 31 is used to suck the component to be transported. When the raw material is transported to the position to be processed, the suction cup member 31 sucks the raw material through gas. After the suction is completed, the rotating body 21 transports the raw material to the processing position. The gas path can be closed to make the raw material fall to the processing position for processing. After the processing is completed, the processed product is adsorbed and transported to the next process; alternatively, the suction cup member 31 can continuously adsorb the raw material for processing and then transport it to the next process after the processing is completed. This can reduce the steps in the processing process and improve the processing efficiency; by using the suction cup member 31 to adsorb the raw material and the processed product, compared with clamping, the probability of damage to the raw material and the product can be reduced, protecting the product and the raw material from being damaged; generally, the raw material of the battery chip is a silicon wafer. To ensure the yield rate of the produced product, the suction cup is used to adsorb the silicon wafer, so that the silicon wafer will not be damaged during the movement process, ensuring the yield rate of the product.

[0034] Please refer to Figure 1 and Figure 3 , in one embodiment, the suction cup member 31 includes a suction cup 311 and a suction attachment 312. One side of the suction attachment 312 is used to connect with the connecting arm 22, and the other side of the suction attachment 312 is used to adsorb the suction cup 311. The suction cup 311 is used to suck the component to be transported. The suction cup 311 sucks the raw material and the processed product. In this way, the suction cup 311 needs to be switched on and off frequently. Due to the frequent switching, the suction cup 311 may be damaged, and then it needs to be repaired and replaced. By using the suction attachment 312 to adsorb the suction cup 311, when disassembling the suction cup 311, only the suction attachment 312 needs to be turned off to stop the adsorption, and then the suction cup 311 can be disassembled. Compared with the prior art in which the suction cup 311 is installed on the connecting arm 22 by bolts, the disassembly of the suction cup 311 in this connection method is simpler, and the repair and replacement of the suction cup 311 can be achieved faster.

[0035] Please refer to Figure 1 and Figure 3, in one embodiment, the swing arm structure 100 further includes a first air pipe interface 7 and a second air pipe interface 8. One end of the first air pipe interface 7 communicates with the inner cavity of the suction cup 311, and the other end of the first air pipe interface 7 is used to communicate with an external pneumatic mechanism. The first end of the second air pipe interface 8 communicates with the inner cavity of the suction accessory 312, and the second end of the second air pipe interface 8 is used to communicate with another external pneumatic mechanism. When it is necessary to connect the suction cup 311 and the suction accessory 312, start the external pneumatic mechanism connected to the second air pipe interface 7, so that the air in the suction accessory 312 will be pumped away, and the suction accessory 312 will suck the suction cup 311 tightly, thus completing the connection between the suction accessory 312 and the suction cup 311. When disassembly is required, the external pneumatic mechanism connected to the second air pipe interface 8 injects gas into the inner cavity of the suction accessory 312, so that the suction accessory 312 will not suck the suction cup 311 tightly, and the suction accessory 312 and the suction cup 311 can be disassembled. When it is necessary for the suction cup 311 to suck the component to be transported, start the external pneumatic mechanism connected to the first air pipe interface 7, so that the air in the suction cup 311 will be pumped away, and the suction cup 311 will suck the component to be transported tightly, thus completing the subsequent transportation. When it is necessary to place the component to be transported, the external pneumatic mechanism connected to the first air pipe interface 7 injects gas into the inner cavity of the suction cup 311, so that the suction cup 311 will not suck the component to be transported tightly, and the component to be transported will fall to the predetermined position. An external pneumatic mechanism is connected to the suction cup 311 through the first air pipe interface 7, and another external pneumatic mechanism is connected to the suction accessory 312 through the second air pipe interface 8, so that both the suction cup 311 and the suction accessory 312 can be controlled independently, and the situation where the suction accessory 312 and the suction cup 311 are loosened simultaneously will not occur, preventing the situation where the suction accessory 312 no longer sucks tightly simultaneously when placing materials, resulting in the simultaneous dropping of the suction cup 311. In a specific embodiment, the pneumatic mechanism can be a vacuum generator.

[0036] Please refer to Figure 1 and Figure 3 , in one embodiment, the swing arm assembly 2 further includes a locking member 4. The connecting arm 22 is formed with a first mounting hole, and the suction accessory 312 is formed with a second mounting hole. The locking member 4 passes through the first mounting hole and is installed in the second mounting hole. Pass the locking member 4 through the first mounting hole, and then install one end extending out of the first mounting hole in the second mounting hole, so that the suction accessory 312 is locked. Through the locking member 4, the firmness of the connection can be improved, preventing the situation of dropping.

[0037] Furthermore, the number of the first mounting holes is multiple, the number of the second mounting holes is multiple, and the number of the locking members 4 is multiple. The number of the multiple first mounting holes, the number of the multiple second mounting holes, and the number of the multiple locking holes are equal and are arranged in one-to-one correspondence, which can further improve the connection strength between the suction accessory 312 and the connecting arm 22, and further prevent the suction accessory 312 from dropping.

[0038] Furthermore, a card foot can be provided on the connecting arm 22, and a card slot can be provided on the adsorption member 312, and the card foot can be engaged in the card slot, so that the connecting arm 22 and the adsorption member 312 can be firmly connected. By providing the card foot and cooperating with the card slot, compared with the connection method of the locking member 4, installation and disassembly are more convenient, and the efficiency of installation and disassembly is improved.

[0039] Furthermore, the number of the pins is multiple, the number of the slots is multiple, the number of the multiple slots and the number of the multiple pins are equal, and are arranged one-to-one, which can also improve the connection strength between the connecting arm 22 and the adsorption member 312.

[0040] See also Figure 1 and Figure 3 In one embodiment, the swing arm assembly 2 further includes a fixing member 5, which is mounted on the locking member 4, and the fixing member 5 abuts against the side of the connecting arm 22 away from the adsorption member 312. Specifically, after the locking member 4 is installed, the fixing member 5 is sleeved and installed on the locking member 4 until the fixing member 5 abuts against the connecting arm 22, so that the locking member 4 can be fixed to prevent the locking member 4 from being separated from the first mounting hole and the second mounting hole, thereby achieving the effect of fixing the locking member 4.

[0041] See also Figure 1 and Figure 3 In one embodiment, the fixing member 5 includes a fastener 51, a first fixing block 52 and two second fixing blocks 53. The two second fixing blocks 53 are respectively connected to the two ends of the first fixing block 52. A gap 54 is formed between the two second fixing blocks 53. The first fixing block 52 is formed with a fixing hole 521. The gap 54 and the fixing hole 521 are communicated with each other. The two second fixing blocks 53 are both formed with a threaded hole 531 communicated with the gap 54. The first fixing block 52 is installed on the locking member 4 through the fixing hole 521. The fastener 51 is installed on the other threaded hole 531 through one threaded hole 531, so that the two second fixing blocks 53 are close to each other. Specifically, the first fixing block 52 is sleeved on the locking member 4 through the fixing hole 521, and then the fastener 51 is installed on the other threaded hole 531 through a threaded hole 531. In this way, during the locking process, the two second fixing holes 521 will be brought closer to each other, and the spacing of the gap 54 will be reduced, so that the inner wall of the fixing hole 521 is pressed against the locking member 4, and the fixing member 5 is in contact with the connecting arm 22, so that the locking member 4 can be prevented from continuing to rotate and move, thereby achieving the effect of fixing the locking member 4.

[0042] See also Figure 1 and Figure 2, in one embodiment, the frame assembly 1 includes a fixed frame 11 and a driving component 12 mounted on the fixed frame 11. The output shaft of the driving component 12 is drivingly connected to the main body 21. When it is necessary to transport raw materials or processed products, start the driving component 12, so that the output shaft of the driving component 12 rotates, and the output shaft of the driving component 12 drives the main body 21 to rotate, thereby realizing the movement of the driving connecting arm 22; by setting the driving component 12, there is no need to manually rotate the main body 21, and automatic transportation is realized.

[0043] Please refer to Figure 1 and Figure 2 , in one embodiment, the driving component 12 includes a servo motor 121 and a speed reducer 122 that are drivingly connected to each other. The output shaft of the speed reducer 122 is drivingly connected to the main body 21. By setting the speed reducer 122, the rotation speed of the servo motor 121 can be reduced and the torque can be increased, so as to ensure that the servo motor 121 can drive the main body 21 to rotate; the servo motor 121 is set as a power element, and the servo motor 121 can realize closed-loop control of position, speed and torque, can accurately follow the control instruction, and achieve highly accurate position positioning and speed control, overcoming the possible step-out problem of the stepping motor; the servo motor 121 has a relatively high rated speed, generally up to 2000 to 3000 revolutions per minute, or even higher, and the torque remains good during high-speed operation, so that the output torque of the speed reducer 122 can drive the main body 21 to rotate.

[0044] Please refer to Figure 1 and Figure 2 , in one embodiment, the swing arm mechanism 100 further includes a control panel 6. A display screen 61 and a key 62 are formed on the control panel 6. The control panel 6 is signal-connected to the servo motor 121. The operator can adjust the rotation speed of the servo motor 121 through the key 62, so as to adjust the rotation speed of the connecting arm 22; the operator can also observe the real-time state of the swing arm mechanism 100 through the display screen 61, which enables the operator to quickly understand the real-time state of the swing arm mechanism 100.
