Description

Technical Field

[0001] The utility model relates to the technical field of coating, and particularly relates to a two-stage double-station coating machine. Background Art

[0002] Traditional coating machines use a single coating head for coating. During the processing, the next workpiece can only be processed after the previous one is completed. For example, the utility model patent with the authorization announcement number CN 213727492 U discloses a high-precision on-line dispensing coating machine, which uses a single dispensing head for dispensing and can only process one workpiece at a time, resulting in low processing efficiency. Although there are also coating devices with double stations in the prior art, different transport lines are set for each station, making the whole device complex in structure, high in cost, and difficult to control the dispensing coating accuracy. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a two-stage double-station coating machine, which has a simple structure, high precision, can complete the coating of two workpieces simultaneously, and has high processing efficiency.

[0004] Specifically, the utility model discloses a two-stage double-station coating machine, comprising:

[0005] A frame;

[0006] A coating device, comprising a moving module, a first coating component and a second coating component, wherein the first coating component and the second coating component move under the drive of the moving module;

[0007] A transport device, located below the coating device, comprising a first transport line and a second transport line, and the first transport line is docked with the second transport line;

[0008] A detection device, arranged on the side of the coating device.

[0009] The advantage of adopting the above technical solution is that two transport devices are set to realize simultaneous double-station gluing, with a simple structure, high coating precision, and improved processing efficiency.

[0010] Furthermore, both the first transport line and the second transport line comprise a transmission chain, a sprocket and a driving member. The two transmission chains are installed through the same profile frame, and a width adjustment component is installed under the profile frame.

[0011] The advantage of adopting the above technical solution is that the cooperation between the transmission chain and the sprocket ensures the transmission precision. At the same time, a width adjustment component is also set to jointly adjust the width of the second transport line and the first transport line to meet the use requirements of products with different widths.

[0012] Further, the transport device further includes a positioning and blocking assembly, which is arranged between the first transport line and the second transport line and at the rear side of the second transport line, and includes a baffle and an extending cylinder, and the baffle is connected to the output end of the extending cylinder.

[0013] The advantage of adopting the above technical solution is that the setting of the blocking and positioning assembly realizes product positioning. When the product is transported on the transport device, the baffle descends to stop the product at the set position, ensuring the coating accuracy.

[0014] Further, both the first coating assembly and the second coating assembly include a coating head and a valve arranged above the coating head, and an air inlet member is connected to the side of the coating head.

[0015] The advantage of adopting the above technical solution is that the air inlet assembly arranged on the side of the coating head realizes the atomization effect, making the coating more uniform.

[0016] Further, the moving module is provided with a mounting plate, the mounting plate is provided with a guide rail, and the first coating assembly and the second coating assembly are respectively connected to the guide rail through sliders.

[0017] The advantage of adopting the above technical solution is that the first coating assembly and the second coating assembly can move left and right to change the distance, which is suitable for products of different sizes. Since the products on the two workstations are exactly the same, the two coating heads can move together to complete the coating of the two products, ensuring that the coating quality remains consistent.

[0018] Further, the width adjustment assembly includes: a ball screw, a moving block, a moving shaft and a driving motor. The moving shaft and the ball screw are arranged along the direction perpendicular to the product transport direction. One side of the profile frame is connected to the moving block, and the moving block moves along the ball screw and the moving shaft.

[0019] The advantage of adopting the above technical solution is that the setting of the ball screw and the moving shaft makes the moving block move smoothly and with high precision, ensuring the dimensional accuracy between the profile frames and preventing the product from falling off the profile frames.

[0020] Further, the detection device includes a detection camera, and the detection camera is connected to the moving module through a fixing plate.

[0021] The advantage of adopting the above technical solution is that the setting of the detection camera can detect the coating quality and prevent uncoated products from flowing into the next working step.

[0022] Further, an exhaust gas discharge assembly is also arranged on the side of the transport device, which includes a connecting plate. A plurality of air inlet holes are arranged on the connecting plate, and a gas collecting box is arranged outside the connecting plate. The gas collecting box is connected to a transmission pipeline.

[0023] The advantage of adopting the above technical solution is that during the coating process, the gas in the equipment enters the gas collection box through the air inlet holes, and then is transported through the transmission pipeline for centralized treatment, avoiding the impact of the coating substance on the environment.

[0024] Furthermore, the extending cylinder is vertically arranged and faces the outside of the transportation device, and the end of the baffle has a downward bending part.

[0025] The advantage of adopting the above technical solution is that since the extending cylinder is arranged facing the outside, after the extending end extends, the baffle moves upward and outward, allowing the product to flow through. After the product passes, the extending end drops, and the stop block blocks the product, achieving precise positioning. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will further describe the present invention in detail with reference to the drawings.

[0034] As Figures 1-4 shown, the present invention discloses a two-stage double-station coating machine, including:

[0035] The frame 1 is provided with a plurality of protective plates and an openable upper cover on the outside;

[0036] The coating device includes a moving module 2, a first coating component 21 and a second coating component 22, and the first coating component 21 and the second coating component 22 move under the drive of the moving module 2;

[0037] The transportation device is located below the coating device and includes a first transportation line 3 and a second transportation line 4, and the first transportation line 3 and the second transportation line 4 are docked; the product is transported from the end of the first transportation line 3 to the first transportation line 3 and the second transportation line 4, and then is coated together on the two transportation lines, and after completion, it is transported out through the tail of the second transportation line 4 to complete the processing;

[0038] The detection device 5 is arranged on the side of the coating device;

[0039] The control display can control the processing speed, the width of the transportation device, etc.

[0040] The beneficial effect of adopting the above technical solution is that two transportation devices are arranged to realize simultaneous glue coating at two work positions, the structure is simple, the coating accuracy is high, and the processing efficiency is improved.

[0041] In some embodiments, both the first transportation line 3 and the second transportation line 4 include a transmission chain 31, a sprocket 32 and a driving member 33. The two transmission chains 31 are installed through the same profile frame 34. A width adjustment component 6 is installed below the profile frame 34. The driving member 33 is a motor, and the motor drives the sprocket 32 to rotate to further drive the symmetrically arranged transmission chains 31 to drive. The product is transported along the transmission chain 31, and both sides of the profile frame 34 also play a role in limiting. A cleaning box 8 is also arranged outside the profile frame 34 for cleaning the coating head 211.

[0042] Furthermore, the width adjustment component 6 includes: a ball screw 61, a moving block 62, a moving shaft 63 and a driving motor. The moving shaft 63 and the ball screw 61 are arranged along the direction perpendicular to the product transportation direction. One side of the profile frame 34 is connected to the moving block 62, and the moving block 62 moves along the ball screw 61 and the moving shaft 63. The driving motor drives the ball screw 61 to rotate to drive the moving block 62 to slide on the moving shaft 63. The arrangement of the ball screw 61 and the moving shaft 63 makes the moving block 62 move smoothly and with high precision, ensuring the dimensional accuracy between the profile frames 34 and preventing the product from falling off the profile frames 34.

[0043] In some embodiments, the transportation device further includes a positioning and blocking component, which is arranged between the first transportation line 3 and the second transportation line 4 and behind the second transportation line 4, and includes a baffle 341 and a telescopic cylinder 342. The baffle 341 is connected to the output end of the telescopic cylinder 342.

[0044] The extending cylinder 342 is vertically arranged and faces the outside of the conveying device. The end of the baffle 341 has a downward bending part. Since the extending cylinder 342 is arranged towards the outside, after the extending end extends, the baffle 341 moves upward and outward, allowing the product to flow through. During the transportation of the product, there will be no obstruction, and the baffle 341 will not scrape or collide with the parts on the surface of the product during the passage of the product. When the extending end drops, the stop block blocks the product to achieve precise positioning.

[0045] In some embodiments, both the first coating assembly 21 and the second coating assembly 22 include a coating head 211 and a valve 212 arranged above the coating head 211. An air inlet member 213 is connected to the side of the coating head 211. The valve 212 controls the on-off of the glue, and the air inlet member 213 is connected to a gas source to atomize and spray the glue, making the coating more uniform.

[0046] Furthermore, the moving module 2 has degrees of freedom in three directions: x, y, and z. The moving module 2 is provided with a mounting plate 23, and the mounting plate 23 is provided with a guide rail 24. The guide rail 24 is horizontally arranged, and the first coating assembly 21 and the second coating assembly 22 are respectively connected to the guide rail 24 through sliders.

[0047] The advantage of adopting the above technical solution is that the first coating assembly 21 and the second coating assembly 22 can move left and right to change the distance, which is suitable for products of different sizes. Since the products on the two workstations are exactly the same, the two coating heads 211 can move together to complete the coating of the two products, ensuring that the coating quality remains consistent.

[0048] Furthermore, the detection device 5 includes a detection camera, and the detection camera is connected to the moving module 2 through a fixing plate. The setting of the detection camera can detect the coating quality and prevent uncoated products from flowing into the next working step.

[0049] In some embodiments, an exhaust gas discharge assembly is further provided on the side of the conveying device, including a connecting plate 7. A plurality of air inlet holes 71 are arranged on the connecting plate 7. A gas collecting box 72 is arranged outside the connecting plate 7. The gas collecting box 72 is connected to a transmission pipeline 73, and an air suction fan is arranged in the gas collecting box 72 to continuously suck air. During the coating process, the gas in the equipment enters the gas collecting box 72 through the air inlet holes 71, and then is transmitted through the transmission pipeline 73 for centralized treatment to avoid the coating substance from affecting the environment.

[0050] During the working process, first, the front side of the conveying device is docked with the feeding equipment, and the rear side is docked with the discharging equipment. After the product is fed, it is first transported to the second conveying line 4 through the first conveying line 3. At this time, the baffle 341 descends to block the product. At this time, the second conveying line 4 stops moving, and the first conveying line 3 continues to feed, so that the product is located under the two coating heads 211. The coating heads 211 descend, and at the same time, the two products are coated. After the coating is completed, the two products are transported from the rear side of the second conveying line 4 to the discharging device, and the conveying device continues to transport the products for coating, improving the coating efficiency.

[0051] For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
