Description

Technical Field

[0001] The utility model relates to a workpiece blanking robot, in particular to a blanking robot jig capable of synchronously performing disassembly and suction. Background Art

[0002] The silver plating process of the power module involves the process of opening the cover of the hanger, removing the cover, and taking out the product. Please refer to Figure 4 The cover 100 has a hollow hole 101, which is aligned with the silver-plated area 102 of the power module. The cover 100 is locked by screws 103. The existing method of removing the cover and removing the workpiece generally uses a servo or electric screwdriver for disassembly. Not only is the operation process complicated, but the efficiency is also low and cannot meet the process requirements. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a blanking robot fixture which can accurately align with the screw, avoid rigid contact between the sleeve and the screw, and can simultaneously remove the screw and absorb the cover in response to the shortcomings of the existing technology.

[0004] In order to solve the above technical problems, the present utility model adopts the following technical solutions.

[0005] The cam is provided with a plurality of transmission wheels and a motor for driving the plurality of transmission wheels to rotate synchronously; the axle of the transmission wheel passes through the support plate and extends downward; the lower end of the axle is coaxially connected to a parallel coupling; the lower end of the parallel coupling is coaxially connected to a vertical rod; the lower end of the vertical rod is provided with a screw sleeve that can slide up and down; the vertical rod is provided with a spring; the spring is clamped between the parallel coupling and the screw sleeve; the bottom of the support plate is fixed with a cylinder; the telescopic shaft at the lower end of the cylinder is fixedly connected to a workpiece suction cup; the screw sleeve passes through the workpiece suction cup and the two rotate in coordination.

[0006] Preferably, a driving wheel is provided on the driving shaft of the motor, and the driving wheel is connected to the plurality of transmission wheels via a belt transmission.

[0007] Preferably, a plurality of tension wheels are provided on the supporting plate, and the tension wheel is provided between two adjacent transmission wheels, and the belt passes around the tension wheel.

[0008] Preferably, a negative pressure chamber is provided in the workpiece suction cup.

[0011] In the blanking robot jig for synchronous disassembly and suction disclosed by the present invention, the upper end of the main body bracket is used to fixedly connect to the six-axis robot, and the motor on the main body bracket can drive multiple transmission wheels to rotate synchronously by belt transmission or the like. When the six-axis robot drives the main body bracket to move so that the screw sleeve and the screw are aligned one by one and contact each other, the cylinder drives the workpiece suction cup to extend and adsorb the cover, and the motor first causes the multiple transmission wheels to rotate slowly. Under the elastic force exerted by the spring, the screw sleeve and the screw are flexibly in contact.

[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0017] The utility model discloses a cutting robot fixture which can dismantle and absorb materials synchronously. Figures 1 to 4As shown, it includes a main bracket 1, a supporting plate 2 is fixed at the lower end of the main bracket 1, a plurality of transmission wheels 3 and a motor 4 for driving the plurality of transmission wheels 3 to rotate synchronously are provided on the support plate 2, the wheel axle 30 of the transmission wheel 3 passes through the support plate 2 and extends downward, the lower end of the wheel axle 30 is coaxially connected with a parallel coupling 5, the lower end of the parallel coupling 5 is coaxially connected with a vertical rod 6, the lower end of the vertical rod 6 is sleeved with a screw sleeve 7 that can slide up and down, the vertical rod 6 is sleeved with a spring 8, the spring 8 is clamped between the parallel coupling 5 and the screw sleeve 7, the bottom of the support plate 2 is fixed with a cylinder 9, the telescopic shaft 90 at the lower end of the cylinder 9 is fixedly connected to a workpiece suction cup 10, the screw sleeve 7 passes through the workpiece suction cup 10 and the two rotate in coordination.

[0018] In the above structure, the upper end of the main support 1 is used to be fixedly connected to the six-axis robot. The motor 4 on the main support 1 can drive multiple transmission wheels 3 to rotate synchronously through belt transmission or the like. When the six-axis robot drives the main support 1 to move so that the screw sleeve 7 and the screw 103 are aligned one by one and contact each other, the cylinder 9 drives the workpiece suction cup 10 to extend and adsorb the cover 100. Because the cover 100 fits tightly with the product, it also indirectly adsorbs the product. The motor 4 first causes multiple transmission wheels 3 to rotate slowly. Under the elastic force applied by the spring 8, the screw sleeve 7 and the screw 103 are in flexible contact. When the screw sleeve 7 rotates slowly to align with the screw 103, the screw sleeve 7 will elastically fit on the screw 103. After all the screw sleeves 7 are accurately fitted, the motor 4 increases the speed so that all the screws 103 are unscrewed at the same time. The workpiece suction cup 10 synchronously absorbs the cover 100 and is driven to move to the target workstation by the six-axis robot. Compared with the existing technology, the utility model can accurately align with the screw, avoid rigid contact between the sleeve and the screw, and realize the simultaneous removal of the screw and suction of the lid and the product, which not only simplifies the operation steps but also improves work efficiency. In addition, it avoids contamination of the product due to direct contact between the suction cup sponge and the product.

[0019] Regarding the preferred driving mode between the motor 4 and the plurality of transmission wheels 3, Figures 1 to 3 As shown, a driving wheel 40 is provided on the driving shaft of the motor 4, and the driving wheel 40 is connected to the plurality of transmission wheels 3 via a belt 11. The belt 11 is in meshing relationship with the driving wheel 40 and the transmission wheels 3, and its function is to prevent the belt from slipping.

[0020] In order to further improve the tension of the belt 11 , in this embodiment, a plurality of tensioning wheels 12 are provided on the supporting plate 2 . The tensioning wheels 12 are provided between two adjacent transmission wheels 3 , and the belt 11 passes around the tensioning wheels 12 .

[0021] As a preferred embodiment, a negative pressure chamber 13 is provided in the workpiece suction cup 10. In practical applications, the workpiece suction cup 10 is connected to an external air source to generate negative pressure in the negative pressure chamber 13, and the negative pressure is used to absorb the cover 100.

[0022] On this basis, in order to make the workpiece suction cup 10 and the cover 100 fit tightly together, in this embodiment, a sponge 14 covering the negative pressure cavity 13 is fixed to the bottom of the workpiece suction cup 10 .

[0023] This embodiment also has the function of automatically sensing the position of the fixture, see Figure 1 , a plurality of photoelectric switches 16 are provided on the workpiece suction cup 10. However, in practical applications, the device used in the present invention is not limited to a photoelectric switch, and may also be other sensors with equivalent functions.

[0024] In the specific working process of this embodiment, the six-axis robot stops the fixture at a height of 5MM above the lid, and the cylinder is in the extended state. Then the motor runs at a slow speed of 0.2 revolutions per second. The robot drops about 8MM-10MM and buckles onto the lid. The motor slowly rotates to align the 12-point socket and the hexagonal screw. At the same time, the vacuum generator is turned on, and the homemade sponge sucks the lid and the two products under the lid. The compression spring will buckle the 12-point socket into the screw head. The motor drives the transmission wheel to rotate and then speeds up to run at a speed of 3 revolutions per second to unscrew the screw. When the motor rotates, the six-axis robot arm will rise synchronously to allow the screw to withdraw. After the screw is unscrewed, the robot places the lid and the product to other stations. When placing the lid, the cylinder will pull up and then extend to prevent the screw head from being trapped in the sleeve and better allow the lid to fall off to the designated station. The four photoelectric switches used in this embodiment play a protective role. If the product or lid is missed during the pick-up and placement process, the system will promptly issue an alarm prompt and make a shutdown response. In actual applications, please refer to Figure 4 There are 5*3 covers on one side of the hanger, with 2 products at the bottom of each cover, and the products are arranged in a 5*6 arrangement.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
