Description

Technical Field

[0001] This invention relates to the field of paint production technology, and in particular to an automatic cap-laying device for paint production. Background Technology

[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving protective, decorative, marking, and other special purposes. The authoritative Chinese book on coatings, *Coating Technology*, defines it as follows: "Coating is a material that can be applied to the surface of an object using different application techniques to form a firmly adhering, continuous solid film with a certain strength. This film is commonly referred to as a coating film, also known as a paint film or coating layer."

[0003] Currently, after paint is filled, the paint cans need to be capped. Before capping, the paint can lid needs to be placed on top of the paint can. However, the existing method is to place the filled paint can on a conveyor belt, then manually place the lid on the paint can, and then transport it to the next capping process. However, manual operation not only has a low degree of automation, but also relatively high labor costs in long-term production, which is not conducive to large-scale production. Secondly, workers' operation is subject to subjective consciousness. If they are not in a good mental state, the quality of cap placement will be reduced (displacement will occur), which will greatly affect the quality of subsequent capping and thus increase the defect rate of products. Based on this, we propose an automatic cap placement device for paint production. Summary of the Invention

[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0031] like Figure 1-10 As shown,

[0032] An automatic cap-laying device for paint production includes a fixed frame 1, a platform 2, a left-right moving clamping mechanism 3, a front-back moving clamping mechanism 4, and a cap-laying mechanism 5. One end of the fixed frame 1 is connected to the platform 2, and the left-right moving clamping mechanism 3, the front-back moving clamping mechanism 4, and the cap-laying mechanism 5 are respectively arranged on the platform 2. By providing the left-right moving clamping mechanism 3, the front-back moving clamping mechanism 4, and the cap-laying mechanism 5, automatic cap-laying operation can be realized, which overcomes the shortcomings of manual operation. It not only greatly reduces labor costs, but also has a high degree of automation, which is conducive to large-scale production by enterprises. At the same time, since the cap-laying device is used for automatic cap-laying, the quality of each cap-laying is basically the same, which effectively ensures the quality of cap-laying, and thus effectively ensures the quality of subsequent capping, greatly reducing the defect rate.

[0033] The left-right moving clamping mechanism 3 includes a first driving device 6, which is mounted on the platform 2. A first moving rod 7 and a second moving rod 8 are respectively connected to the first driving device 6.

The drive device 6 is used to drive the first moving rod 7 and the second moving rod 8 to rotate simultaneously, thereby causing the first clamping part 13 and the second clamping part 14 to move relative to each other to clamp the cover or move in the opposite direction to release the cover. It can be understood that when the first drive device 6 is started, it can drive the first moving rod 7 and the second moving rod 8 to rotate simultaneously, thereby synchronously driving the first moving part 9, the second moving part 10, the third moving part 11 and the fourth moving part 12 to move, so that the first clamping part 13 and the second clamping part 14 can clamp the workpiece in opposite directions or release the workpiece (cover) in the opposite direction, achieving the effect of left and right clamping.

The second driving device 15 is used to drive the third moving rod 16 and the fourth moving rod 17 to move forward and backward simultaneously, thereby causing the third clamping part 18 and the fourth clamping part 19 to move relative to each other to clamp the cover or move in the opposite direction to release the cover. It can be understood that activating the second driving device 15 can drive the third moving rod 16 and the fourth moving rod 17 to move relative to each other or in the opposite direction simultaneously, thereby causing the third clamping part 18 and the fourth clamping part 19 to move relative to each other or in the opposite direction to clamp or release the workpiece, thus achieving the effect of forward and backward clamping.

It can be understood that starting the third driving device 20 can drive the rotating part 21 to rotate, and then use the vacuum suction cups 22 to suck up or release the lids, thereby realizing an automatic lid-releasing operation.

The lifting frame 60 is fixedly connected to the platform 2.

[0044] The working principle of this invention is as follows: This cap-laying device can be installed on the entire production line. Below the cap-laying device is a conveying mechanism, which transports the cans already filled with paint to the area directly below this device. This process mainly involves cap-laying, and the next process is cap-pressing. During operation, the first servo motor 23 and the first reduction motor 24 are started first, which in turn drive the first synchronous pulley 25 to work. Then, the first moving rod 7 and the second moving rod 8 are driven to rotate synchronously. When the first moving rod 7 and the second moving rod 8 rotate, they can drive the first moving part 9 and the second moving part 10 to clamp inward or release outward (the third moving part 11 and the fourth moving part 12 clamp inward or release outward synchronously), thereby driving the first clamping part... Part 13 and the second clamping part 14 move inward or outward; in addition, when the second servo motor 38 and the second reduction motor 39 are started, the first lead screw 40 will rotate, thereby synchronously driving the second synchronous pulley 41 and the third synchronous pulley 42 to move, causing the third moving rod 16 or the fourth moving rod 17 to move forward or backward, thereby clamping the cover in the front and back by the second clamping rod 46; when performing the cover placement operation, the fourth push cylinder 53 can be started first to push the vacuum suction cup 22 to contact the cover upward, and then the vacuum suction cup 22 can be started to suck the cover. At this time, the first push cylinder 31 can be started to drive the support plate 33 away from the bottom surface of the cover (before the cover is placed, the support plate 33 is located on the bottom surface of the cover, the purpose of which is to support the cover). (Supporting the entire lid), then the fourth push cylinder 53 will drive the vacuum suction cup 22 to move down, at which point the bottom lid can be pulled out (because the left and right moving clamping mechanism 3 and the front and back moving clamping mechanism 4 are still clamping the lids in other positions, the bottom lid can be pulled out when the suction force is greater than the clamping force). Then, the rotating cylinder 49 is activated, rotating 180 degrees to flip the lid to the bottom. Then, when the vacuum suction cup 22 is closed (the fourth push cylinder 53 can drive the vacuum suction cup 22 to move down, so that the lid contacts the top surface of the can), the lid can accurately fall onto the can. At this time, the third push cylinder 52 is in the original position of the fourth push cylinder 53, and can continue to work in a cycle, thereby realizing the lid removal and placement operation. It should be noted that after the bottom cover is removed, the first push cylinder 31 drives the support plate 33 forward to its original position. Then, the second push cylinder 32 is activated to drive the first clamping block 34 and the first clamping rod 35 to return to their original positions, releasing the entire cover (left and right). Similarly, the second servo motor 38 drives the first moving block 45 and the second clamping rod 46 to return to their original positions, releasing the entire cover (front and back). At this time, the entire cover will move down to the top surface of the support plate 33, and the cover placement operation will continue. In addition, when the third servo motor 57 and the third reduction motor 58 are activated, the lifting rod 59 and the lifting frame 60 can be driven to move up and down, thereby driving the platform 2 to move up and down and adjusting the position of the platform 2 for placing the cover.

[0045] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
