[0027] Reference Figures 1 to 4 According to an embodiment of the utility model, a clamp disassembly mechanism is used to disassemble a coil clamp 800, which includes a mechanical arm 100, a gripping device 200 and an unlocking device 300. The gripping device 200 is used to grip the upper clamping plate 810 of the coil clamp 800, and the gripping device 200 is installed on the mechanical arm 100; the unlocking device 300 includes a driving module 310 and two unlocking members 320 for pushing the hook 830 of the coil clamp 800 to rotate, the driving module 310 is installed on the gripping device 200, the two unlocking members 320 are connected to the driving module 310, the two unlocking members 320 are arranged in a horizontal direction, and the gripping device 200 is located between the two unlocking members 320, wherein the driving module 310 can drive the two unlocking members 320 to move in a horizontal direction close to or away from the gripping device 200.

[0028] The clamp disassembly mechanism provided by the utility model can adjust the initial distance between the two unlocking members 320 according to the distance between the hooks 830 on the opposite ends of the upper clamp 810 during the process of disassembling the coil clamp 800, so that all the hooks 830 of the coil clamps 800 of different sizes can be located between the two unlocking members 320, and then the driving module 310 can drive the two unlocking members 320 to move closer to the gripping device 200, so that the unlocking members 320 can push all the hooks 830 on the corresponding end of the upper clamp 810 to rotate and disengage from the lower clamp 820, and finally the robot 100 can move the upper clamp 810 through the gripping device 200 to complete the clamp disassembly work. Therefore, the clamp disassembly mechanism provided by the utility model can disassemble coil clamps 800 of different sizes and has good versatility. In addition, the clamp disassembly mechanism does not need to be provided with four unlocking cylinders and four pressing members, so that the structure on the clamp disassembly mechanism is simple and convenient for installation and maintenance.

[0029] Reference Figure 2 and Figure 3 In some embodiments, a mounting portion 230 is provided at one horizontal end of the gripping device 200, the mounting portion 230 is connected to the robotic arm 100, and the driving module 310 is installed on the upper side of the gripping device 200. With the above arrangement, the unlocking device 300 and the gripping device 200 are reasonably arranged, and the unlocking device 300 and the gripping device 200 can be installed together first and then installed on the robotic arm 100, which is more convenient to install.

[0030] Reference Figure 2 and Figure 3 In some embodiments, the gripping device 200 includes a mounting plate 210 and a suction cup module 220, wherein one horizontal end of the mounting plate 210 is connected to the mounting portion 230, the suction cup module 220 and the driving module 310 are mounted on the other end of the mounting plate 210, and the driving module 310 is mounted on the upper side of the mounting plate 210. Thus, the suction cup module 220 and the driving module 310 can be firstly mounted on the mounting plate 210, and then the mounting plate 210 is connected to the robot arm 100 through the mounting portion 230.

[0031] It should be noted that, in some embodiments, the above-mentioned gripping device 200 can also be arranged in other ways. For example, the above-mentioned suction cup module 220 can be replaced with an electromagnet, and part or all of the upper clamping plate 810 of the coil clamp 800 is made of a magnetic material that can be attracted by the electromagnet.

[0032] Reference Figure 2 and Figure 3In some embodiments, the driving module 310 is configured as a double-axis cylinder, and the two opposite ends of the double-axis cylinder have output shafts 311, and the output shafts 311 are connected to the corresponding unlocking members 320. With the above configuration, the unlocking device 300 only needs to use one double-axis cylinder to drive the two unlocking members 320 to move. In this way, the structure of the unlocking device 300 is simpler and easier to install.

[0033] It should be noted that, in some embodiments, the above-mentioned driving module 310 can also be set up in other ways. For example, the driving module 310 includes a motor and two racks. The output shaft 311 of the motor is equipped with a gear. The two racks are arranged in parallel. The gear is located between the two racks and meshes with the two racks for transmission. The two unlocking members 320 are connected to the two racks one by one. In this way, only one motor is needed to drive the two unlocking members 320 to move horizontally towards or away from the gripping device 200.

[0034] Reference Figures 2 to 3 In some embodiments, the unlocking member 320 includes an unlocking push rod 321, and the upper ends of all the hooks 830 of the coil clamp 800 are provided with grooves 831 for the corresponding unlocking push rods 321 to be inserted. During the disassembly of the clamp, the two unlocking push rods 321 first move and are inserted into the grooves 831 of the corresponding hooks 830, and then push the hooks 830 to rotate and disengage from the lower clamp 820 of the coil clamp 800. At the same time, the unlocking push rod 321 can apply an upward thrust to the hook 830, so that the upper clamp 810 of the coil clamp 800 moves upward and disengages from the lower clamp 820.

[0035] Reference Figure 2 and Figure 3 In some embodiments, the unlocking member 320 includes a connecting plate 322, one end of the connecting plate 322 is connected to the driving module 310, and the other end is provided with a mounting groove 3221, and the opposite side walls of the mounting groove 3221 are connected to the unlocking push rod 321. The above arrangement can improve the structural strength of the unlocking member 320 and effectively prevent the unlocking push rod 321 from bending and deforming during operation.

[0036] Reference Figure 3 In some embodiments, the connecting plate 322 is detachably connected to the driving module 310, wherein the connecting plate 322 can be detachably mounted on the driving module 310 by means of bolts, snaps, etc., so that the two unlocking members 320 can be disassembled and replaced.

[0037] It should be noted that, in a specific implementation process, the unlocking member 320 may also be arranged in other ways. For example, the unlocking member 320 includes a long push plate, and the push plate is connected to the driving device.

[0038] Reference Figure 1In some embodiments, the fixture disassembly mechanism includes a fixture disassembly table 500 for placing the coil fixture 800 and a unloading mechanism 600 for transferring and transporting the workpiece. The unloading mechanism 600 is located on one side of the fixture disassembly table 500. During the fixture disassembly process, the robot arm 100 places the coil fixture 800 with the coil clamped on the fixture disassembly table 500 through the gripping device 200, and then the unlocking device 300 drives the lower ends of all the hooks 830 on the upper clamping plate 810 to detach from the lower clamping plate 820. Then the robot arm 100 removes the upper clamping plate 810 through the gripping device 200, and the unloading mechanism 600 removes the magnetic plate and the coil on the upper clamping plate 810.

[0039] Reference Figure 1 In some embodiments, a clamping device 700 is provided on the fixture disassembly table 500, and the clamping device 700 is used to clamp and fix the lower clamping plate 820 of the coil fixture 800. In this way, during the fixture disassembly process, the clamping device 700 first fixes the lower clamping plate 820 of the coil fixture 800 at a predetermined position on the fixture disassembly table 500, which is convenient for the subsequent robot arm 100 to disassemble the upper clamping plate 810 of the coil fixture 800, and also convenient for the unloading mechanism 600 to remove the magnetic plate and coil on the upper clamping plate 810.

[0040] In the specific implementation process, the clamping device 700 can be set in a variety of ways. For example, the clamping device 700 may include two relatively arranged clamping members and two cylinders. The two cylinders drive the two clamping members to move closer together to clamp the lower clamping plate 820 of the coil clamp 800 in a one-to-one manner; the clamping device 700 may also include at least two suction cups arranged on the clamp disassembly table 500. After the coil clamp 800 is placed on the clamp disassembly table 500, the coil clamp 800 can be adsorbed and fixed by the suction cups.

[0041] Reference Figure 1 In some embodiments, the fixture disassembly mechanism includes a fixture recovery mechanism 400 for receiving the coil fixture 800, and the fixture recovery mechanism 400 is located on one side of the fixture disassembly table 500. Therefore, during the fixture disassembly process, the robot arm 100 can transport the upper clamping plate 810 and the lower clamping plate 820 of the coil fixture 800 to the fixture recovery mechanism 400, and the fixture recovery mechanism 400 transports the upper clamping plate 810 and the lower clamping plate 820 of the coil fixture 800 to the assembly station, so that the coil fixture 800 can be reused.

[0042] In a specific implementation, the clamp recovery mechanism 400 may include a conveyor belt device or a conveyor roller device.
