[0033] Reference Figures 1 to 3 The medical negative pressure ball taking mechanical hand tool and its control method according to the embodiment of the present application are described.

[0034] As Figures 1 to 3 shown, the medical negative pressure ball taking mechanical hand tool according to the embodiment of the present application comprises a support plate 100, a sleeve 200 arranged on the support plate 100, the sleeve 200 being in a hollow cylindrical shape, the axis of the sleeve 200 being arranged along the up-down direction, two accommodation holes 210 being symmetrically arranged on the end of the sleeve 200 close to the support plate 100 along the radial direction of the sleeve 200, a suction assembly 300 arranged on the wall of the sleeve 200, the suction assembly 300 being arranged in the middle section of the sleeve 200 along the radial direction of the sleeve 200, the suction assembly 300 being arranged towards the inside of the sleeve 200, the suction assembly 300 being used to suck the side wall of the medical negative pressure ball 1, a clamping assembly 400 arranged on the support plate 100, the clamping assembly 400 being arranged in the two accommodation holes 210, the clamping assembly 400 comprising two first air cylinders 410 and two clamping jaws 420, the two first air cylinders 410 being arranged in the two accommodation holes 210 respectively, the two first air cylinders 410 being respectively provided with the clamping jaws 420 towards the side of the axis of the sleeve 200, the two first air cylinders 410 driving the two clamping jaws 420 to approach and move away from each other along the radial direction of the sleeve 200 to realize the clamping action.

[0035] As Figures 1 to 3As shown, a flange face 220 is provided at one end of the sleeve 200 near the support plate 100, and the sleeve 200 is connected to the support plate 100 through the flange face 220. It also includes a reinforcing block 230 and a fixing block 240. The reinforcing block 230 is located on the outside of the sleeve 200, and the fixing block 240 is located on the inside of the sleeve 200 corresponding to the reinforcing block 230. The reinforcing block 230 is connected to the support plate 100, and the fixing block 240 is connected to the reinforcing block 230 by screws that penetrate the sleeve 200. The fixing block 240 and the reinforcing block 230 clamp the sleeve 200. This medical negative pressure ball retrieval robotic arm fixture also includes a fixing seat 110, which is located on the side of the support plate 100 facing away from the sleeve 200. The fixing seat 110 is used to fix the support plate 100 to the robotic arm of the injection molding machine. A clearance groove 250 is provided on the sleeve 200, and the clearance groove 250 is arranged along the axial direction of the sleeve 200. The suction assembly 300 includes: a fixing plate 310, which is disposed on the outer wall of the sleeve 200 and arranged radially along the sleeve 200; a second cylinder 320, which is arranged radially along the sleeve 200 on the fixing plate; and a soft rubber suction nozzle 330, which is disposed at one end of the second cylinder 320 facing the axis of the sleeve 200. The fixing plate 310 is provided with an elongated groove 311, through which the fixed position of the second cylinder 320 is adjusted, thereby adjusting the distance of the soft rubber suction nozzle 330 relative to the medical negative pressure bulb 1.

[0036] The suction component 300 is inserted through the clearance hole 210 in the middle section of the sleeve 200. When the medical negative pressure ball removal robot jig is put onto the medical negative pressure ball 1, the second cylinder 320 drives the soft rubber suction nozzle 330 to suck up the medical negative pressure ball 1 located inside the sleeve 200, so as to prevent the medical negative pressure ball 1 from shaking inside the sleeve 200 and causing scratches to the medical negative pressure ball 1.

[0037] By setting reinforcement components and fixing blocks 240 on the support plate 100, the reliability of the connection between the sleeve 200 and the support plate 100 is further improved. Both grippers 420 are made of plastic to prevent damage to the medical negative pressure ball 1. The first cylinder 410 drives the grippers 420 to hold the head of the medical negative pressure ball 1, thus fixing and assisting in pulling out the medical negative pressure ball 1. The sleeve 200 needs to withstand the expansion pressure of the medical negative pressure ball 1 after inflation; therefore, the wall thickness of the sleeve 200 needs to be sufficiently thick. At the same time, the weight of the sleeve 200 cannot be too heavy, and it needs to meet the load limit of the robotic arm on the injection molding machine. Therefore, the wall thickness of the sleeve 200 is designed to be approximately 2mm. Multiple sets of reinforcement components and fixing blocks 240 are evenly distributed along the circumference of the sleeve 200 to reinforce the sleeve 200 and prevent it from cracking due to the expansion of the medical negative pressure ball 1.

[0038] A control method for a medical negative pressure ball removal robotic jig according to a second aspect of the present invention includes:

[0039] Adjust the position of the second cylinder 320 on the fixed plate 310 according to the size of the medical negative pressure ball 1;

[0040] The second cylinder 320 operates to drive the soft rubber suction nozzle 330 to suck up the side wall of the medical negative pressure ball 1;

[0041] The two first cylinders 410 operate, driving the two grippers 420 to move synchronously toward the axis of the sleeve 200, clamping the head of the medical negative pressure ball 1.

[0042] like Figures 1 to 3 As shown, after the mold is opened, the robotic arm moves the fixture and puts it onto the medical negative pressure ball 1. Then, the medical negative pressure ball 1 is inflated by blowing air. The soft rubber nozzle 330 sucks on the medical negative pressure ball 1 to prevent it from shaking inside the sleeve 200. The first cylinder 410 drives the gripper 420 to clamp the head of the medical negative pressure ball 1. Then, the robotic arm takes the medical negative pressure ball 1 and places it on the conveyor belt.

[0043] Therefore, this medical negative pressure ball retrieval robot jig and its control method use a suction component 300 to stabilize the medical negative pressure ball 1, preventing the medical negative pressure ball 1 from being scratched during the clamping process, and then use a clamping component 400 to clamp the head of the medical negative pressure ball 1, automatically completing the action of retrieving the medical negative pressure ball 1. The entire process does not require manual assistance, avoids tearing the medical negative pressure ball 1 and causing deformation, and at the same time improves production efficiency and reduces labor costs.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
