[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0036] Combine Figures 1 to 4 As shown, the utility model proposes an automatic loading device for valve oil seals of multiple models, which can realize the automatic loading of valve oil seals a, improve the loading speed and improve the overall assembly efficiency. Among them, the automatic loading device mainly includes structural components such as a loading vibration plate 1, a stand 30, a collaborative robot 3 and a loading platform 4.

[0037] Combine Figure 1 、 Figure 3 and Figure 4 As shown, a material bin 11 is provided on one side of the feeding vibration plate 1. A valve oil seal a is stored in the material bin 11. The discharge port of the material bin 11 is located above the feeding vibration plate 1. The valve oil seal a enters the interior of the feeding vibration plate 1 from the material bin 11. The feeding vibration plate 1 automatically and orderly arranges the disordered workpieces through vibration. After a series of track screening or posture changes, they finally arrive at the discharge port in a unified state according to the requirements of assembly or processing. This reduces the operation of manual screening, reduces the error rate, and improves the efficiency of feeding.

[0038] Combine Figure 1 and Figure 2 As shown, a material receiving mechanism 2 is provided at the discharge port of the feeding vibration plate 1 , wherein the material receiving mechanism 2 includes structural components such as a slide cylinder 21 , a slider 22 and a material receiving block 23 .

[0039] Combine Figure 2 As shown, a slide cylinder 21 is provided with a slide rail, on which a slider 22 is slidably connected. The slide cylinder 21 can drive the slider 22 to move along the slide rail, and a material receiving block 23 is fixedly connected to the top of the slider 22. The outer contour of the material receiving block 23 is long and strip-shaped. The material receiving block 23 is provided with multiple placement grooves 24. The placement grooves 24 are adapted to accommodate the valve oil seal a and are connected to the discharge port of the feeding vibrating plate 1. When the valve oil seal a enters the placement groove 24, the slide cylinder 21 drives the material receiving block 23 to move, causing the placement groove 24 and the discharge port of the material receiving block 23 to be misaligned. The material receiving block 23 can prevent subsequent valve oil seals a from entering the placement groove 24. The slide cylinder 21 is also provided with a limit buffer block 25 for limiting the movement of the slider 22.

[0040] Combine Figure 2 As shown, a first material detection sensor 241 is provided on the material receiving block 23 and below the placement groove 24. When the first material detection sensor 241 detects that the valve oil seal a has entered the placement groove 24, the slide cylinder 21 drives the material receiving block 23 to move laterally, causing the placement groove 24 to be misaligned with the discharge port, thereby preventing subsequent valve oil seals a from entering the placement groove 24. When the first material detection sensor 241 detects that the valve oil seal a has left the placement groove 24, the slide cylinder 21 drives the material receiving block 23 to move, causing the placement groove 24 to be aligned with the discharge port again, allowing the valve oil seal a to enter the placement groove 24.

[0041] Combine Figure 1 、 Figure 3 and Figure 4As shown, multiple feeding vibration plates 1 are provided, and are separated on both sides of the vertical frame 30 and the loading platform 4. Among them, a collaborative robot 3 is provided on the vertical frame 30. The collaborative robot 3 is used to grab the valve oil seal a stored in the placement groove 24 and transport the valve oil seal a to the loading platform 4 to wait for the subsequent transportation or assembly mechanism to carry out the next transfer or assembly operation.

[0042] Combine Figure 1 As shown, the collaborative robot 3 mainly includes structural components such as a base 31, a swing arm 32, a connecting base 33, a rotating shaft 34, a pitch-changing mechanism 35, and air grippers 36. The bottom of the base 31 is fixedly connected to the stand 30, and the top of the base 31 is connected to one end of the swing arm 32, which can rotate horizontally relative to the base 31. The other end of the swing arm 32 is provided with a connecting base 33, which can rotate horizontally relative to the swing arm 32. The connecting base 33 is provided with a vertically arranged rotating shaft 34, which can rotate and move longitudinally relative to the connecting base 33. The bottom end of the rotating shaft 34 is connected to the pitch-changing mechanism 35, which is provided with multiple air grippers 36. The pitch-changing mechanism 35 can drive the multiple air grippers 36 to move horizontally and adjust the spacing between the air grippers 36. At the same time, the air grippers 36 can complete the grasping of the valve oil seal a. The variable pitch mechanism 35 adopts a servo cam slot variable pitch mechanism. When grabbing the valve oil seal a, the servo motor drives the air grippers 36 to move laterally to adjust the spacing between the air grippers 36 so that the spacing is equal to the spacing of the placement slots 24, making it easier for the air grippers 36 to grab the valve oil seal a. After grabbing, the valve oil seal a is uniformly placed on the workbench 4. Figure 2 As shown, a second material detection sensor 361 is provided at the end of the air gripper 36 for detecting whether the valve oil seal a has been grasped, so as to drive the collaborative robot 3 to clamp the valve oil seal a to the work platform 4.

[0043] The operation process of the automatic feeding device of the utility model is as follows:

[0044] The valve oil seal a enters the interior of the loading vibration plate 1 from the material bin 11, and undergoes vibration screening of the loading vibration plate 1, so that the valve oil seal a automatically arrives at the discharge port in a unified posture according to the requirements of assembly or processing, and smoothly enters the interior of the placement groove 24 opened by the receiving block 23. The first material detection sensor 241 detects that the valve oil seal a enters the placement groove 24, and the slide cylinder 21 drives the receiving block 23 to move horizontally, so that the placement groove 24 and the discharge port are misaligned to prevent subsequent valve oil seals a from entering; the collaborative robot 3 takes action, drives the air claw 36 to move to the top of the placement groove 24 to complete the clamping of the valve oil seal a, and transports the valve oil seal a to the loading platform 4 to wait for subsequent other transportation and assembly mechanisms to transport or assemble the valve oil seal a.

[0045] Combine Figures 1 to 4As shown, the utility model proposes an automatic feeding device for valve oil seals of multiple models, which vibrates and screens the valve oil seals a through a feeding vibration disk 1, and adjusts the valve oil seals a to a uniform posture for discharge. At the same time, by arranging a receiving mechanism 2 at the discharge port of the feeding vibration disk 1, the valve oil seals a can be placed in the placement groove 24 opened by the receiving block 23, and by arranging a collaborative robot 3, the valve oil seals a in the placement groove 24 can be clamped and transported to the loading platform 4. The whole process does not require manual operation, thereby realizing the automation of the feeding of the valve oil seals a and further improving the efficiency of production and assembly. By adding a first material detection sensor 241 and a second material detection sensor 361 to detect the valve oil seals a, the degree of automation of the feeding process is improved, the assembly efficiency is greatly improved, and it meets the development requirements of modern industry.

[0046] Of course, the above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention and should be protected by the present invention.
