Fig. 1-2 are schematic structural views of the feeding device of this embodiment. The feeding device A realizes the picking and placing of the magnetic workpiece D by sucking and placing the magnetic workpiece D, thereby realizing the subsequent operation process of the magnetic workpiece D. As shown in fig. 1-2, the feeding device a includes a buffering component 1, an attracting component 2 and a first driving mechanism 3. Wherein, buffering subassembly 1 is connected with first actuating mechanism 3, and the piece 2 that draws sets up in buffering subassembly 1, and through the removal of control first actuating mechanism 3 in order to drive the piece 2 that draws and do straight reciprocating motion, the realization is got and is put magnetic workpiece D.

The damping assembly 1 has a damping channel 11. The two ends of the buffer channel 11 are communicated, that is, the buffer assembly 1 has two buffer channels 11 with communicated openings. The absorbing part 2 is arranged in the buffer channel 11 and can be controlled to do linear reciprocating motion in the buffer channel 11. The feeding device A controls the distance from the suction piece 2 to the end part of the buffer channel 11 (namely the distance from the suction piece 2 to the magnetic workpiece D), so that the magnetic workpiece D is taken and placed.

The buffer sleeve 12 and the buffer stop 13 are fixedly connected, and the buffer passage 11 is arranged in the buffer sleeve 12 and the buffer stop 13, as shown in fig. 3 and 4. The cross sectional area of the buffer stop block 13 is larger than that of the buffer sleeve 12, so that the attaching area of the feeding device A and the magnetic workpiece D can be increased, and the stability of the magnetic workpiece D and the feeding device A during adsorption movement is improved. In this embodiment, the material of the buffer component 1 is a non-magnetic conductive material, which can prevent the magnetic workpiece D from being adsorbed by the buffer component 1, and prevent the magnetic workpiece D from being taken and placed under effective control.

In other alternative implementations, the cushion assembly 1 may be a one-piece hollow cylindrical structure.

The first drive mechanism 3 includes a cylinder 31 and a piston assembly 32. The cylinder 31 includes an air chamber 33 having an opening. In the present embodiment, the side of the cylinder 31 having the opening is fixedly connected to the cushion sleeve 12 so that the air chamber 33 and the cushion passage 11 communicate. Specifically, a first end of the piston assembly 32 is disposed in the air chamber 33, and a second end of the piston assembly 32 extends out of an opening of the air chamber 33 into the buffer passage 11 to be fixedly connected with the attraction part 2. In the present embodiment, the piston assembly 32 is driven to move in the air chamber 33 and the buffer channel 11, so as to drive the suction element 2 to reciprocate in the buffer channel 11. Specifically, the attraction piece 2 is configured to move to a first position to form an attraction state with the magnetic workpiece D and to move to a second position to form a release state with the magnetic workpiece D. The first position is a position where the end of the engaging member 2 is flush with the end of the bump stopper 13, as shown in fig. 3. The air cavity 33 is sized as desired.

The second end of the piston rod 322 projects from the air chamber 33 into the buffer passage 11. The piston 323 divides the air chamber 33 into two closed chambers, left and right. In order to prevent the left and right chambers of the piston 323 from air leakage, a piston seal ring is arranged on the piston 323. In addition, the wear-resistant ring is arranged on the piston 323, so that the guidance of the piston assembly 32 can be improved, the abrasion of a piston sealing ring can be reduced, and the friction resistance can be reduced. The wear-resistant ring is made of polyurethane, polytetrafluoroethylene, cloth-sandwiched synthetic resin and the like. The piston 323 is usually made of aluminum alloy, cast iron, or the like. The piston rod 322 is the most important stressed part in the first driving mechanism 3, and high carbon steel, hard chrome-plated surface, or stainless steel is usually used to prevent corrosion and improve the wear resistance of the sealing ring.

The piston rod 322 has a shoulder 321, the shoulder 321 being proximate the second end. The diameter of the shoulder 321 is larger than the diameter of the air chamber 33 and smaller than the diameter of the buffer passage 11.

In this embodiment, the first driving mechanism 3 is further provided with a sealing device 34 fixedly connected to the cylinder 31 and disposed on one side of the cylinder having an opening for sealing the air chamber 33 to prevent air leakage from between the piston rod 322 and the sealing device 34 during the movement of the piston rod 322.

In other alternative implementations, the first drive mechanism 3 further includes an end cap. The end cover is fixedly connected with one end of the cylinder 31 with an opening, and a sealing ring and a dust ring are arranged on the end cover, so that air leakage from the edge of the piston rod 322 to the outside can be prevented, and external dust can be prevented from entering the air cavity 33. The end cover is provided with a guide sleeve to improve the guiding precision of the first driving mechanism 3, bear a small amount of transverse load on the piston rod 322, reduce the downward bending amount when the piston rod 322 extends out, and prolong the service life of the first driving mechanism 3.

The cylinder 31 further includes a first intake port 311 and a second intake port 312. The first inlet 311 and the second inlet 312 are respectively disposed at two sides of the piston 323, that is, the first inlet 311 and the second inlet 312 are respectively communicated with chambers at two sides of the piston 323. Specifically, the first intake port 311 communicates with the left chamber of the cylinder 31, and the second intake port 312 communicates with the right chamber of the cylinder 31. When air is supplied from the first air inlet 311, the air pressure in the left chamber is gradually increased, pushing the piston assembly 32 to move in the first direction, so as to push the engaging member 2 to move to the side away from the air chamber 33. The first direction is a direction in which the piston assembly 32 moves to the outside of the cylinder 31. During the movement, the gas in the right chamber of the piston 323 is gradually discharged from the second gas inlet 312, the left chamber is gradually increased, and the right chamber is gradually decreased.

When air is supplied from the second air inlet 312, the air pressure in the right chamber is gradually increased, and the piston assembly 32 is pushed to move in the second direction, so that the engaging member 2 is pushed to move to the side close to the air chamber 33. The second direction is opposite to the first direction. During the movement, the gas in the left chamber of the piston 323 is gradually discharged from the first gas inlet 311, the right chamber is gradually increased, and the left chamber is gradually decreased.

In practical use, the first intake port 311 and the second intake port 312 are provided with an exhaust throttle valve or an intake throttle valve, the air pump is connected with the exhaust throttle valve (or the intake throttle valve), and the flow rate of inlet air and the flow rate of outlet air of the corresponding chambers are adjusted through the exhaust throttle valve (or the intake throttle valve), so as to control the movement direction and the movement speed of the piston assembly 32.

The size of the absorbing part 2 is slightly smaller than the diameter of the buffering channel 11, so that the absorbing part 2 can move in a straight line in the buffering channel 11, and meanwhile, the bending degree of the absorbing part 2 can be reduced. The material of the engaging element 2 is a ferromagnetic material that is not magnetized, for example iron. The engaging member 2 has a mounting hole 21 (threaded hole) and a thread is correspondingly provided at an end of the piston rod 322. The piston rod 322 is installed in the installation hole 21 to be screw-coupled with the attraction member 2, as shown in fig. 5.

The engaging member 2 includes a connecting portion 22 and an engaging portion 23, and the engaging portion 23 has a cross-sectional area larger than that of the connecting portion 22, so that the connecting portion 22 and the engaging portion 23 form a step structure, as shown in fig. 5. The size of the attraction part 23 is slightly smaller than that of the buffer channel 11, so that the attraction part 23 can move in the buffer channel 11, and meanwhile, the magnetic workpiece D can be adsorbed in the largest area, and the adsorption stability is improved.

The feeding device a of the present embodiment further includes a connecting member 4, as shown in fig. 1 and 2. The connecting member 4 includes a first connecting portion 41 and a second connecting portion 42. The first connecting portion 41 is fixedly connected to the cylinder 31. The second connecting portion 42 has a driving mounting hole 421 for connecting with a telescopic rod of the second driving mechanism. The side surface of the second connecting portion 42 is further provided with a third connecting hole 422 for fixedly connecting with the buffer stop 13. Correspondingly, the cushion stopper 13 has a first attaching portion 131 and a second attaching portion 132. The cross-sectional area of the first fitting portion 131 is larger than that of the first portion 121. The second fitting portion 132 is located below the first fitting portion 131 and extends in the longitudinal direction. The second fitting portion 132 is fixedly connected to the second connecting portion 42 of the connecting member 4. The second attaching portion 132 further has a rotation mounting hole 132a for rotatably connecting with the worktable through a rotation shaft. The rotation of the feeding device A and the workbench is realized by controlling the extension of the air cylinder arranged in the driving mounting hole 421.

In the embodiment, the piston assembly 32 and the attraction part 2 are pushed to move to the right side by increasing the pressure of the left chamber through the air intake from the first air inlet 311, and when the attraction part 2 pushes to a position flush with the end of the buffer stop 13, the magnetic workpiece D is attracted to form a magnetic attraction state with the magnetic workpiece D. When it is necessary to release the magnetic workpiece D, the piston assembly 32 and the attraction member 2 are pushed to the left side by the pressure of the chamber on the right side increased by the air intake from the second air intake port 312, and when the attraction member 2 is moved to have a predetermined distance from the end of the bump stopper 13, the magnetic workpiece D is released. Thereby completing the pick-and-place of the magnetic workpiece D.

The workbench B is rotationally connected with a buffer stop block 13 of the feeding device A. The second driving mechanism C is fixedly connected with the driving mounting hole 421 of the feeding device a. When the second driving mechanism C is controlled to extend or contract, the second driving mechanism C drives the feeding device a to rotate relative to the workbench B, so that the angle between the end surface of the buffer stop 13 and the workbench B is changed as required.

The initial state of the feeding system of this embodiment is that the terminal surface of buffer stop 13 is 95 degrees with workstation B's contained angle, and specific angle is set for according to the demand.

Specifically, the process of taking and placing the magnetic workpiece D by the feeding system is as follows:

In the present embodiment, the upper end D2 and the lower end D1 of the L-shaped magnetic workpiece D are connected by a soft plate, and thus it is necessary to fix the upper end D2 and the lower end D1 of the magnetic workpiece D at the same time.

(2) The robot arm grasps the lower end D1 of the magnetic workpiece D.
