Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and in particular to an automatic valve spraying equipment and system based on human-machine collaboration. Background Art

[0002] Valve plastic spraying is a surface treatment process widely used in the valve manufacturing industry. Its main purpose is to form a uniform and solid protective film on the valve surface to improve the corrosion resistance, wear resistance and aesthetics of the valve. The plastic spraying process is based on the principle of electrostatic adsorption. Through the high-voltage electrostatic field formed between the spray gun and the valve, the plastic powder coating is charged and evenly adsorbed on the valve surface. Subsequently, the plastic powder is melted, leveled and solidified by heating, and finally a dense protective film is formed.

[0003] However, the existing valve spraying process has some technical problems in practical application, which affects production efficiency and environmental protection. First, during the loading and unloading process of the valve, the valve cover and valve seat usually require manual assistance, which not only increases the labor intensity of the operator, but also leads to a long loading and unloading time, affecting the overall production efficiency. Secondly, after the powder spraying is completed, the pre-positioning of the valve seat and valve cover and the transportation to the assembly workshop still require manual operation, which is not only time-consuming and labor-intensive, but may also lead to inaccurate positioning, affecting the subsequent valve core installation quality.

[0004] In addition, the problem of plastic powder falling during the spraying process cannot be ignored. Plastic powder will inevitably fall into the spraying chamber during the spraying process, which not only causes waste of plastic powder and increases production costs, but also may pollute the environment and affect the cleanliness of the working environment and the health of operators.

The valve seat loading and unloading assembly 7 is installed on the outer side of the first loading bin 121; the first positioning assembly includes a first clamping seat 151, a front end clamping component 2, a rear end clamping component 3, and a first driving rod 21.

The rear end of the side wall of the first clamping seat 151 is installed with the rear end clamping component 3.

The vertical tube 92 is provided in the middle of the top surface of the horizontal tube 91, and a lower assembly hole 921 is opened at the top of the vertical tube 92; In the second step, the front clamping component 2 is inserted into the rear clamping component 3 to drive the rear clamping component 3 to block the opening of the vertical pipe 92 of the valve seat and limit the rotation of the valve seat; In the third step, when the valve seat is in the first powder spraying bin 122 and the first drying bin 123, the front clamping component 2 drives the rear clamping component 3 and the valve seat to rotate; In the fourth step, the first positioning assembly cooperates with the second positioning assembly 4 to pre-join the valve cover to the valve seat; In the fourth step, the valve seat upper and lower material assembly 7 removes the pre-jointed valve seat and valve cover so that the valve cover and the valve seat can be transferred synchronously.

[0022] In the above scheme: 1. The setting of processing chamber 1 has the following effects: 1.1. Two annular processing areas are set in a processing chamber 1, one for independent powder spraying processing of valve seat, and the other for independent powder spraying processing of valve cover, so as to realize efficient and rapid processing of valve seat and valve cover, and the overall layout is more compact and occupies a smaller area; 1.2.

[0023] In this embodiment, the front end clamping component 2 includes a slide plate 22, a first folding plate 23, a second folding plate 24, a fixed plate and an insert plate 26. The slide plate 22 is slidably embedded in the first clamping seat 151. The outer end side wall of the slide plate 22 is vertically provided with a first folding plate 23. The outer end of the first folding plate 23 is rotatably connected to the second folding plate 24 and a first motor 231 is installed at the rotating connection. The output end of the first driving rod 21 is connected to the first folding plate 23. The outer end of the second folding plate 24 is rotatably provided with a circular front plate 25 and a second motor 241 is installed at the rotating connection. The side wall of the front plate 25 is vertically provided with a vertically arranged insert plate 26, and the end of the insert plate 26 is a sloped structure with the slope facing upward.

[0024] In the above scheme: the first motor 231 can drive the plug plate 26 to rotate, so that the plug plate 26 can be arranged perpendicularly to the first annular track 15, or can be arranged parallel to the first annular track 15, and the plug plate 26 can face the inner support tube 32. When the first driving rod 21 drives the first folding plate 23 to move inward, the slide plate 22 is received in the first clamping seat 151, and the plug plate 26 can be inserted into the inner support tube 32 to achieve clamping and positioning of the valve seat; In the powder spraying and drying process, the second motor 241 can drive the plug plate 26 to rotate, thereby driving the valve seat to rotate around the rear plate 31, so as to achieve uniform powder spraying and drying of the valve seat.

[0025] In the present embodiment, the rear end clamping component 3 comprises a rear plate 31, an inner support cylinder 32, a lower seat body 33, and a blocking block 34. The inner end of the rear plate 31 is vertically fixed to the rear end of the first clamping seat 151, and the outer end side wall of the rear plate 31 is rotatably connected to the inner support cylinder 32.

In the second step, the insert plate 26 is adjusted to be arranged parallel to the first clamp seat 151, and the end of the insert plate 26 faces the inner support tube 32. The insert plate enters the upper top gap and the upper blocking block leaves the inner support tube, and the blocking block is inserted into the vertical pipe.

[0026] In the above scheme: when loading, the plug plate 26 is adjusted to be vertically distributed with the first clamp seat 151, and a gap is left between the plug plate 26 and the inner support tube 32 for the valve seat to enter. The first loading manipulator 72 first sets the transverse tube 91 of the valve seat on the inner support tube 32, and then the first loading manipulator 72 keeps clamping, and the first motor 231 drives the plug plate 26 to rotate and adjust it to face the inner support tube 32; because it is necessary to ensure that the outer wall of the inner support tube 32 is flat when not in use, the blocking block 34 needs to be designed as a rectangle, and the two ends of the blocking block 34 are designed as arc surfaces, which can adapt to the shape of the vertical tube; The first driving rod 21 drives the slide plate 22 to move inward along the first clamp seat 151, so that the insert plate 26 is inserted between the guide plates 331, and the inclined surface of the insert plate 26 pushes the blocking block 34, so that the blocking block 34 extends outward from the rectangular hole 321 and extends into the vertical tube; when the insert plate 26 is separated from the inner support tube 32, the spring rod 341 drives the blocking block 34 to descend and be collected into the inner support tube 32. Since the blocking block 34 is designed as a cuboid, when it is inserted into the vertical pipe, a gap will be left between it and the vertical pipe. In order to solve this problem, the following solution is given: In this embodiment, a tooth groove 261 is provided on the top surface of the plug plate 26, a transmission component is installed inside the blocking block 34, a blocking side plate 35 is symmetrically rotated installed on the top surface of the blocking block 34, and a first gear 351 is installed at the rotating connection, and the transmission component is meshed and connected with the first gear 351; when the plug plate 26 is inserted, the tooth groove 261 drives the upper transmission component to drive the two groups of blocking side plates 35 to rotate outward synchronously, so that the blocking side plates 35 and the blocking block 34 form a complete blocking circle. The transmission components include a second gear 36, a transmission rod 38, a transmission belt and a third gear 381. The second gear 36 is vertically rotatable and arranged at the inner bottom of the blocking block 34.
