Description

[0002] In the field of mechanical manufacturing, coating is a common surface treatment method that can improve the surface hardness, wear resistance and corrosion resistance of parts, and also beautify the appearance of parts. Traditional coating usually involves multiple processes, including surface treatment before coating, coating process, drying or curing after coating, etc. The whole process is cumbersome and prone to quality problems such as uneven coating and bubbles.

[0003] Traditional coating treatment has problems such as uneven coating and many bubbles. The main reason is that the coating cannot evenly cover the surface of the parts during the coating process, which is mainly caused by the poor fluidity of the coating. In addition, it is also a common problem that bubbles are difficult to completely eliminate after coating. This is related to the volatility of the coating itself and the residual gas factors during the coating process, resulting in unstable coating quality and affecting the appearance and performance of the parts.

[0042] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0043] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] like Figure 1-7 As shown, an embodiment of the present invention provides a coating treatment device for mechanical parts, comprising:

[0045] A coating drive mechanism 10, and a multi-drive detection mechanism 20 is installed on an adjacent side of the coating drive mechanism 10;

[0046] The coating drive mechanism 10 includes a coating inlet and outlet box 11, a support frame 12, a chain drive roller 13, two side support plates 14, two groups of coating straight flat tubes 15 and two groups of coating bent flat tubes 16; the support frame 12 is bolted to the bottom of the coating inlet and outlet box 11, the chain drive roller 13 is installed inside the coating inlet and outlet box 11, the two side support plates 14 are symmetrically bolted to both sides of the chain drive roller 13, the bottoms of the two groups of coating straight flat tubes 15 are bolted to the side support plates 14 respectively, the two groups of coating bent flat tubes 16 are respectively integrally formed and connected with the two groups of coating straight flat tubes 15, each group of coating bent flat tubes 16 and coating straight flat tubes 15 are three, the chain drive roller 13 is installed inside the coating inlet and outlet box 11, and is used to drive the movement of the parts, and the coating bent flat tubes 16 and the coating straight flat tubes 15 together constitute a coating system, which is used to evenly coat the paint on the surface of the parts;

[0047] The coating drive mechanism 10 further includes a notch 111; the notch 111 is opened on one side of the coating inlet and outlet box 11 close to the multi-drive detection mechanism 20, and evenly distributed coating nozzles 17 are installed on adjacent sides of the two groups of coating straight flat tubes 15 and the two groups of coating bent flat tubes 16, and the outer walls of the two groups of coating straight flat tubes 15 are installed with a feed pipe 18, and the feed pipe 18 is located on the outer wall of the coating inlet and outlet box 11 and is installed with a feed valve 19;

[0048] The parts to be coated are placed in the coating inlet and outlet box 11, and the coating is transported to the coating straight flat tube 15 and the coating bent flat tube 16 through the feed pipe 18 and the feed valve 19. The support frame 12 is fixedly installed at the bottom of the coating inlet and outlet box 11 for fixing. The chain drive roller 13 is installed inside the coating inlet and outlet box 11, which drives the parts to move through the chain transmission system. The coating straight flat tube 15 and the coating bent flat tube 16 on the two side support plates 14 and the dense coating nozzles 17 ensure that the coating is evenly coated on the surface of the parts. The part table 30 is set in the slot 111 of the coating drive mechanism 10 through the multi-drive detection mechanism 20, and the parts transported by the chain drive roller 13 are directly transported to the table plate 35.

[0049] A parts table 30, which is located at one side of the coating drive mechanism 10 and is installed on a drive device of the multi-drive detection mechanism 20;

[0050] The control table 35 is controlled to rotate so as to drive the complete visual inspection of the parts. Specifically, the servo motor 32 is controlled to drive the driving pinion 33 to rotate, so that the driving pinion 33 drives the internal gear 34 meshing with it to mesh with the transmission. The internal gear 34 drives the table 35 to rotate under the fixation of the large bearing. In this way, the parts are placed on the table 35, and the rotation of the parts is realized by the rotation of the table 35.

[0051] The vacuum removal and breaking mechanism 50 is installed at one side of the coating drive mechanism 10 and is located below the multi-drive detection mechanism 20 .

[0052] The vacuum removal mechanism 50 includes a mounting frame 51, a vacuum pump 52, a vacuum pipe 53, a vacuum sealing chamber 54, an exhaust pipe 55 and a side bracket 56;

[0053] The vacuum pump 52 is fixedly connected to the bottom of the mounting frame 51, the outer wall of the vacuum sealing chamber 54 passes through one side of the top plate of the mounting frame 51 and is fixed, the evacuation pipe end of the vacuum pump 52 is fixedly connected to the outer wall of the vacuum sealing chamber 54 through the exhaust pipe 53, and one side of the side bracket 56 is fixedly connected to the outer wall of the vacuum sealing chamber 54 on the same side of the mounting frame 51.

[0054] The vacuum removal mechanism 50 also includes a push-pull cylinder 57, a closing cover 58 and a pressure gauge 59. The cylinder end of the push-pull cylinder 57 is bolted to one side of the side bracket 56, and the outer wall of the closing cover 58 is bolted to the gas rod end of the push-pull cylinder 57. The closing cover 58 is sealed at the opening of the vacuum sealing chamber 54, and the pressure gauge 59 is installed on the outer wall of the vacuum sealing chamber 54. The push-pull movement of the closing cover 58 is achieved by controlling the push-pull cylinder 57. When the vacuum sealing chamber 54 needs to be opened or closed, the push-pull cylinder 57 can quickly and accurately control the movement of the closing cover 58 to ensure the sealing and stability of the vacuum sealing chamber. The closing cover 58 is located at the opening of the vacuum sealing chamber 54 and is used to close the vacuum sealing chamber 54 during the bubble treatment process.

[0055] The vacuum sealing chamber forms a closed space through the sealing cover 58 and the mounting frame 51 to prevent external air from entering. The sealing cover 58 is retracted and moved by controlling the push-pull cylinder 57 to separate the sealing cover 58 from the opening of the vacuum sealing chamber 54. At the same time, the lowering cylinder 29 is driven by the screw module 23 to be located at the upper part of the vacuum sealing chamber 54. Then, the lowering cylinder 29 is controlled to start so that the part table 30 is moved into the vacuum sealing chamber 54 as a whole. Then, the electromagnetic plate 212 is controlled to release the adsorption with the part table 30 and fix the position of the part table 30. Subsequently, the output shaft of the lowering cylinder 29 is controlled to retract to the outside of the vacuum sealing chamber 54. Then, the closing cover 58 is driven by the push-pull cylinder 57 to close the opening of the vacuum sealing chamber 54, and the vacuum pump 52 is started. The air in the vacuum sealing chamber 54 is evacuated through the exhaust pipe 53, so that the vacuum pump 52 will extract air from the inside of the vacuum sealing chamber 54, gradually reducing the pressure inside the vacuum sealing chamber 54. During the vacuum exhaust process, the bubbles on the surface of the coated parts will be affected by the surface tension of the coating and the pressure of the internal gas, and gradually float from the depth of the coating to the surface. Then, as the vacuum degree increases, the bubbles burst on the coating surface and release gas. The gas is taken away by the exhaust pipe 53 and enters the vacuum pump 52 for discharge. As the bubbles burst and the air is extracted, the coating will naturally fill the position of the bubbles, making the coating more uniform and dense. After the coating process is completed, the vacuum pump 52 is stopped to allow the outside air to re-enter the vacuum sealing chamber to restore the normal air pressure.

[0056] At this time, the closing cover 58 is driven to move by the push-pull cylinder 57 to open the opening of the vacuum sealing chamber 54, and the parts are ready to be taken out. The lowering cylinder 29 is started to extend it to the inner bottom of the vacuum sealing chamber 54, and the electromagnetic plate 212 is controlled to be adsorbed on one side of the part table 30, and the part table 30 drives the part to move out of the vacuum sealing chamber, so that the part is separated from the vacuum sealing chamber 54, and the screw rod module 23 is controlled to move in the reverse direction to drive the part to move to the coating inlet and outlet box 11 again. At the same time, the coating condition is detected again by the visual detector 27 to ensure the coating quality of the part surface. The chain drive roller 13 is controlled to rotate in the opposite direction, so that the part stops after entering a part of the coating inlet and outlet box 11, and then a layer of coating is applied to the part to ensure the quality and appearance of the coating. Then, the multi-drive detection mechanism 20 drives it to move to the other side of the vacuum removal mechanism 50 for placement.

[0057] In the present embodiment, specifically, the multi-drive detection mechanism 20 includes a support frame 21, a support top plate 22, a screw module 23, a detection frame 26 and two visual detectors 27; the bottom bolt of the support top plate 22 is installed on the top of the support frame 21, the screw module 23 is bolted to the bottom of the support top plate 22, the horizontal side of the nut seat of the screw module 23 is bolted to the same side of the detection frame 26, and the two visual detectors 27 are symmetrically bolted to the two sides of the bottom of the detection frame 26. The two visual detectors 27 are symmetrically inclined at an angle. While the parts rotate, the two visual detectors 27 detect the coating condition of the parts, and the visual detectors 27 can monitor in real time. The coating condition of the part surface is detected, and the part and the visual detector 27 are synchronously driven to move through the nut seat when the screw module 23 is started. In this way, the operator can promptly find areas with insufficient or uneven coating. At the same time, the nut seat of the screw module 23 is started to drive the detection frame 26 on one side to move, so that the detection frame 26 drives the two visual detectors 27 to move. At this time, the nut seat also synchronously drives the lowering cylinder 29 to move, and the electromagnetic plate 212 adsorbs the part table 30 to move. While the part is rotating, it is synchronized with the visual detector 27 to achieve all-round detection of the part coating condition, which not only improves the detection efficiency, but also increases the detection time in this process.

[0058] In the present embodiment, specifically, the multi-drive detection mechanism 20 also includes two guide rails 24, two guide sliders 25, a fixed plate 28, a lowering cylinder 29, a mounting plate 211 and an electromagnetic plate 212; the two guide rails 24 are symmetrically screwed to the two sides of the bottom of the supporting top plate 22, the two guide sliders 25 are respectively slidably connected to the outer side walls of the two guide rails 24, and the two guide rails 24 are screwed to the two sides of the nut seat of the screw module 23; the top of the fixed plate 28 is welded to the bottom of the nut seat of the screw module 23, the lowering cylinder 29 is screwed to the fixed plate 28, one side of the top of the mounting plate 211 is welded to the output shaft of the lowering cylinder 29, and the electromagnetic plate 212 is fixedly connected to one side of the top of the mounting plate 211.

[0064] Step 3: Place the coated parts on the table 35 , and rotate the parts by controlling the table 35 , while monitoring the coating status of the parts in real time through two visual detectors 27 .

[0066] Step 5: Stop the vacuum pump 52 and allow the outside air to re-enter the vacuum sealing chamber 54. After the normal air pressure is restored, the vacuum sealing chamber 54 is opened by driving the sealing cover 58 through the push-pull cylinder 57 to take out the coated parts.
