Description

Technical Field

[0001] The present invention relates to a glove dipping gripper. Background Art

[0002] In glove dipping production, it often involves the co - operation of impregnating the glove surface with glue. According to the previous method, it needs to be done manually, with very low efficiency, wasting a lot of time. Also, since the impregnating glue usually contains chemical substances harmful to the human body, there are certain potential safety hazards to the lives of workers. With the increase in factory production, more and more manufacturers need to complete the impregnation of multiple pairs of gloves at one time. Therefore, the traditional manual operation method urgently needs to be improved. Summary of the Invention

[0003] The present invention solves the above - mentioned technical problems and thus provides a glove dipping gripper to replace manual work for glove dipping, reduce the contact between personnel and the glue, and improve the working efficiency of glove dipping.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A glove dipping gripper, its structural characteristics are:

[0006] At the lower end of the die cross - beam, there are multiple glove dies arranged at intervals along the beam length, with the fingertips facing downwards and the palm surfaces arranged along the beam length direction. The gloves to be dipped are adaptively sleeved on the outer surface of the glove dies. At the upper end of the die cross - beam, there is a pair of adsorption plates made of ferromagnetic material;

[0007] The glove dipping gripper includes a hoisting plate, a pushing device installed at the lower end of the hoisting plate, a linear guide rail, a blanking mechanism, and two dipping mechanisms;

[0008] The two dipping mechanisms are arranged front - to - back and spaced apart. The dipping mechanism at the rear is integrally hoisted at the lower end of the hoisting plate and is relatively fixed to the hoisting plate. The dipping mechanism at the front is integrally hoisted at the lower end of the hoisting plate through a pair of linear guide rails at the lower end of the hoisting plate. Driven by the pushing device, it can extend forward or retract backward along the linear guide rail relative to the dipping mechanism at the rear. The distance between the dipping mechanism at the front when it extends forward in place and the dipping mechanism at the rear can accommodate at least one glove die with the fingertips pointing in the front - to - back direction and the palm surface horizontal to be placed in;

[0009] Any dipping mechanism includes a rotating mechanism and a rotating beam plate that can be rotated by the rotating mechanism. In the initial state, the rotating beam plate horizontally extends along the left - right direction. A pair of electromagnets are respectively arranged on the left and right sides of the lower end. By relying on the magnetic force of the pair of electromagnets to adsorb to a pair of adsorption plates, the hoisting of the die cross - beam with multiple glove dies is formed, and it constitutes a synchronous moving component with the die cross - beam. Driven by the rotating mechanism, it can flip together along the front - to - back direction;

[0010] Each dipping mechanism is configured with a pair of blanking mechanisms for separating the mold crossbeam from the rotating beam plate after dipping is completed.

[0011] The structural features of the present invention also lie in:

[0012] The dipping mechanism at the rear side is integrally fixed and hoisted at the lower end of the hoisting plate by a pair of heightening blocks arranged left and right; the slide rails of a pair of linear guides are horizontally arranged along the front-rear direction and are fixedly installed on the left and right sides at the lower end of the hoisting plate, and the dipping mechanism at the front side is integrally connected between the sliders of the pair of linear guides through a moving beam plate arranged along the front-rear direction; the bottom ends of the heightening blocks are at the same height as the bottom end of the moving beam plate.

[0013] The dipping mechanism includes a servo reduction motor, a rotating shaft, a rotating beam plate, and a pair of electromagnets; the motor shaft of the servo reduction motor is connected to the rotating shaft through a coupling, both ends of the rotating shaft are supported by bearings, the rotating beam plate is initially placed parallelly directly below the rotating shaft and is fixedly connected to the rotating shaft through a fixed ring in the shaft, and the pair of electromagnets are respectively arranged on the left and right sides at the lower end of the rotating beam plate and are distributed corresponding to the distance between a pair of adsorption plates.

[0014] The pushing device is a pushing cylinder.

[0015] A pair of blanking mechanisms are installed on one side where the two rotating beam plates face each other in the two dipping mechanisms, the pair of blanking mechanisms on the rotating beam plate are located between the pair of electromagnets, the blanking mechanism includes a blanking cylinder and a blanking plate installed at the execution end of the blanking cylinder, the blanking plate can be driven by the blanking cylinder to extend downward in place or retract upward to the reset position, and initially there is a vertical gap between the blanking plate and the mold crossbeam adsorbed on the rotating beam plate. When the electromagnet is powered off, the blanking plate that extends downward in place can contact the upper end of the mold crossbeam and push the mold crossbeam downward to separate from the rotating beam plate.

[0016] The glove dipping gripper can be used as a robot end effector as a whole, and a connecting flange is provided at the upper end of the hoisting plate for assembly with the robot end.

[0017] Compared with the prior art, the beneficial effects of the present invention are embodied in:

[0018] The present invention uses two dipping mechanisms to lift the gloves sleeved on multiple glove molds to be dipped in glue, and can drive the multiple glove molds to flip. The distance between the two dipping mechanisms can be adjusted by a pushing device, which can avoid interference when the front and rear glove molds flip. In addition, the present invention uses an electromagnet to lift the mold crossbeam with multiple glove molds, and realizes automatic blanking of the mold crossbeam by power-off of the electromagnet. In addition, a blanking mechanism is added to further ensure the stable blanking of the mold crossbeam. The present invention can be used to complete the operation of impregnating the gloves with glue, replacing manual labor, reducing the labor intensity of manual work and the potential safety hazards associated with manual operation, and improving production efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 5 , the glove dipping gripper structure of this embodiment is as follows:

[0027] At the lower end of the die crossbeam 1, there are multiple glove dies 2 arranged at intervals along the beam length, with their fingertips facing downwards and the palm surfaces arranged along the beam length direction. The gloves to be dipped in glue are adaptively sleeved on the outer surface of the glove dies 2. At the upper end of the die crossbeam 1, there is a pair of adsorption plates 3 made of ferromagnetic material;

[0028] The glove dipping gripper includes a hoisting plate 4, a pushing device 16 installed at the lower end of the hoisting plate 4, linear guide rails 5, a blanking mechanism, and two dipping mechanisms;

[0029] The two dipping mechanisms are arranged facing each other front and back at intervals. The dipping mechanism at the rear is integrally hoisted at the lower end of the hoisting plate 4 and is relatively fixed to the hoisting plate 4. The dipping mechanism at the front is integrally hoisted at the lower end of the hoisting plate 4 through a pair of linear guide rails 5 at the lower end of the hoisting plate 4. Driven by the pushing device 16, it can extend forward or retract backward along the linear guide rails 5 relative to the dipping mechanism at the rear. The distance between the dipping mechanism at the front when it extends forward in place and the dipping mechanism at the rear along the front-back direction can accommodate at least one glove die 2 with its fingertips pointing in the front-back direction and the palm surface horizontal to be placed in;

[0030] Any dipping mechanism includes a rotating mechanism and a rotating beam plate 10 that can be rotated by the rotating mechanism. In the initial state, the rotating beam plate 10 extends horizontally along the left-right direction. A pair of electromagnets 11 are respectively arranged on the left and right sides of the lower end. By relying on the magnetic force of the pair of electromagnets 11, they are adsorbed to the pair of adsorption plates 3 to form the hoisting of the die crossbeam 1 with multiple glove dies 2, and constitute a synchronous motion component with the die crossbeam 1. Driven by the rotating mechanism, it can flip along the front-back direction together;

[0031] Each dipping mechanism is configured with a pair of blanking mechanisms for separating the die crossbeam 1 and the rotating beam plate 10 after dipping is completed.

[0032] The structural setting of this glove dipping gripper also includes:

[0033] The dipping mechanism at the rear is integrally fixed and hoisted at the lower end of the hoisting plate 4 through a pair of heightening blocks 6 arranged left and right; the slide rails of the pair of linear guide rails 5 are horizontally arranged along the front-back direction and are fixedly installed on the left and right sides of the lower end of the hoisting plate 4. The dipping mechanism at the front is integrally connected between the sliders of the pair of linear guide rails 5 through a moving beam plate 7 arranged along the front-back direction; the bottom ends of the heightening blocks 6 and the moving beam plate 7 are at the same height.

[0034] The dipping mechanism includes a servo reduction motor 8, a rotating shaft 9, a rotating beam plate 10, and a pair of electromagnets 11; the motor shaft of the servo reduction motor 8 is connected to the rotating shaft 9 through a coupling 15, and both ends of the rotating shaft 9 are supported by bearings installed in the main bearing seats 12, with shaft end fixing rings 13 provided at both ends and a shaft middle fixing ring 14 in the middle. Initially, the rotating beam plate 10 is placed parallelly directly below the rotating shaft 9 and is fixedly connected to the rotating shaft 9 through the shaft middle fixing ring 14. A pair of electromagnets 11 are respectively arranged on the left and right sides at the lower end of the rotating beam plate 10 and are correspondingly distributed according to the distance between a pair of adsorption plates 3.

[0035] The pushing device 16 is a pushing cylinder.

[0036] A pair of blanking mechanisms are installed on one side where the two rotating beam plates 10 of the two dipping mechanisms face each other. The pair of blanking mechanisms on the rotating beam plate 10 are located between the pair of electromagnets 11. The blanking mechanism includes a blanking cylinder 17 and a blanking plate 18 installed at the execution end of the blanking cylinder 17. The blanking plate 18 can be driven by the blanking cylinder 17 to extend downward in place or retract upward to reset. Initially, there is a vertical gap between the blanking plate 18 and the upper end of the mold cross beam 1 adsorbed on the rotating beam plate 10. When the electromagnets 11 are powered off, the blanking plate 18 that extends downward in place can contact the upper end of the mold cross beam 1 and push the mold cross beam 1 downward to separate from the rotating beam plate 10.

[0037] The glove dipping gripper can be used as the end effector of the robot as a whole. A connecting flange 19 is provided at the upper end of the lifting plate 4 for assembly with the end of the robot, and the glove dipping operation can be carried out in the following manner:

[0038] The electromagnets 11 of the front and rear two dipping mechanisms are powered on, and a pair of electromagnets 11 rely on magnetic force to adsorb on the upper ends of a pair of adsorption plates 3 of the mold cross beam 1 to form the lifting of the mold cross beam 1. At this time, the fingertips of each glove mold 2 with the glove to be dipped face downward, as Figure 4 shown;

[0039] After that, driven by the pushing device 16, the front dipping mechanism extends forward along the linear guide rail 5 to be in place, leaving a distance between the front dipping mechanism and the rear dipping mechanism, and leaving a space between the glove molds 2 on the two dipping mechanisms to avoid interference;

[0040] The robot can drive the gripper as a whole to move downward to immerse the glove in the glue solution, and then the robot can drive the gripper as a whole to move upward to lift the glove out of the liquid surface to drain; this step can be repeated according to different process requirements;

[0041] After that, the servo reduction motor 8 drives the rotary shaft 9 to rotate, driving the glove mold 2 on the mold crossbeam 1 to turn over to a horizontal posture with the palm facing down and the fingertips facing forward. The robot then drives the entire gripper to move again until the glove mold 2 is completely immersed in the glue solution for liquid infiltration on the glove surface. After the infiltration is completely finished, the servo reduction motor 8 drives the rotary shaft 9 to rotate, driving the front and rear glove molds 2 back to their original positions, making the fingertips of the glove mold 2 face down, and the robot lifts the glove out of the liquid surface to drain it;

[0042] After the glove dipping is completed, the pushing device 16 returns to its original position. At this time, the robot can drive the entire gripper to move to the next working station. By de-energizing a pair of electromagnets 11, the mold crossbeam 1 automatically separates from the electromagnets 11 and falls onto the next working station by its own weight. During the process, the feeding cylinder 17 of the feeding mechanism can be extended downward to assist the separation of the mold crossbeam 1 and prevent the unstable separation of the mold crossbeam 1 due to the residual magnetism of the electromagnets 11.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
