Abstract
Description
Technical Field
[0001] This utility model belongs to the field of robot adhesive application technology, specifically relating to an industrial robot adhesive application device. Background Technology
[0002] Industrial robot gluing devices, through the coordinated operation of industrial robots, glue supply mechanisms, glue application mechanisms, and material positioning mechanisms under the control of a control system, can achieve high-precision automatic glue application to material boards. However, a small amount of error still exists during actual processing. When applying glue to the top surface of the material board, to ensure complete coverage, a running allowance needs to be set at the starting position of the material board. Due to this running allowance, the bottom of the glue brush is already lower than the top surface of the material board before contacting it. The brush will first contact the edges and sides of the material board at the starting position. When using high-flow glue, some glue will be applied to the edges and sides of the material board at the starting position, resulting in uneven glue application on the sides and affecting the finished product. Especially when the glue thickness is large, the pressure from the edges of the material board at the starting position on the brush will cause some glue to detach from the brush, resulting in glue overflowing downwards on the sides. This glue overflow accumulation not only affects the finished glue application effect of the material board but also affects the subsequent installation accuracy of the material board.

[0018] Please see Figures 1-4 The present invention provides the following technical solution: an industrial robot gluing device, including a material plate positioning plate 1, a dissolving liquid holding tank plate 2 fixedly connected to the top of the material plate positioning plate 1, an elastic rubber block 21 embedded on one side of the dissolving liquid holding tank plate 2, a rounded chamfer 22 opened at the top of the dissolving liquid holding tank plate 2, a glue circulation attachment belt 3 installed on the outside of the dissolving liquid holding tank plate 2, a guide roller 31 installed on one side of the glue circulation attachment belt 3, a drive roller 32 installed on one side of the glue circulation attachment belt 3, a glue layer scraper 4 provided on one side of the glue circulation attachment belt 3, and a residual glue scraper 41 provided on one side of the glue circulation attachment belt 3, the glue layer scraper 4 and the residual glue scraper 41 are in opposite directions.
[0019] In this implementation scheme: the inner dimensions of the material board positioning plate 1 are set according to the dimensions of the material board. Before applying glue, the material board is installed on the top of the material board positioning plate 1, and the side wall of the material board is attached to the glue circulation attachment belt 3. During the glue application process, the glue brush first contacts the top surface of the glue circulation attachment belt 3. After reaching the predetermined starting position, the glue brush is squeezed and deformed, moving towards the material board. When passing the edge of the material board, the glue circulation attachment belt 3 is supported and squeezed by the dissolving liquid holding tank plate 2 and the elastic rubber block 21. The glue circulation attachment belt 3 squeezes and seals the side wall of the material board, and simultaneously intercepts the bottom end of the glue brush and the glue. By setting the rounded chamfer 22, a small gap is left between the glue circulation attachment belt 3 and the edge of the material board and the top of the side wall of the material board, so that the glue brush can neatly apply glue to the top of the side wall of the material board, and the glue will not overflow onto the side wall surface of the material board. It can also ensure that the glue can completely cover the top of the material board and eliminate the glue brush that cannot be completely and accurately applied from the material board due to the equipment precision. The adhesive application process begins at the top edge. After application, the drive roller 32 drives the adhesive circulation belt 3 to rotate counterclockwise, moving the adhesive-coated belt 3 into the dissolving liquid holding tank 2 and immersing it in the dissolving liquid. This dissolves the adhesive on the surface of the belt 3. The adhesive layer scraper 4 and the residual adhesive scraper 41 then clean the adhesive from the surface of the belt 3, removing any accumulated adhesive. The adhesive layer is thickened to reduce the thickness of the adhesive on the surface of the adhesive circulation belt 3, thereby improving the dissolution effect of the adhesive. Then, the dissolved adhesive is cleaned again by the residual adhesive scraper 41, which can effectively improve the cleaning effect of the adhesive on the surface of the adhesive circulation belt 3. The adhesive circulation belt 3 is driven by the drive roller 32 so that different parts of the adhesive circulation belt 3 can circulate and limit the adhesive brush and overflow adhesive near the side wall of the material plate, so as to avoid the adhesive being irregularly applied to the side wall of the material plate and improve the adhesive application effect of the adhesive brush on the material plate.
[0020] The bottom side wall of the dissolving liquid holding tank plate 2 is provided with a relief groove 23, through which the adhesive circulation attachment belt 3 passes. By setting the relief groove 23, the adhesive circulation attachment belt 3 can be given room, so that the adhesive circulation attachment belt 3 can smoothly circulate on the outer wall of the dissolving liquid holding tank plate 2.
[0021] A drive mechanism 33 is installed on one side of each of the two drive rollers 32, and the two drive rollers 32 rotate synchronously. The drive mechanism 33 can drive the drive rollers 32 to rotate. The drive mechanism 33 consists of a drive motor, two transmission toothed belts and two sets of drive gears. The two gears are installed on the outer wall of the output shaft of the drive motor. The drive motor drives the two transmission toothed belts to move through the gears, and the transmission toothed belts drive the two drive gears to move, thereby driving the drive rollers 32 to rotate.
[0022] A backup scraper 42 is provided above the residual adhesive scraper 41. The backup scraper 42 is in the same direction as the residual adhesive scraper 41. The ends of the adhesive layer scraper 4, the residual adhesive scraper 41, and the backup scraper 42 are all in contact with the adhesive circulation attachment belt 3. The backup scraper 42 serves as a safety measure. If there is still residual adhesive on the surface of the adhesive circulation attachment belt 3 after dissolution and cleaning, the backup scraper 42 can clean it again and gather the residual adhesive. By judging whether there is adhesive residue at the backup scraper 42, the operator can judge the cleaning effect of the adhesive layer scraper 4, the residual adhesive scraper 41, and the dissolving liquid in the dissolving liquid holding tank 2 on the adhesive. This will determine whether it is necessary to stop the machine to replace the dissolving liquid in the dissolving liquid holding tank 2 or to repair the adhesive layer scraper 4 and the residual adhesive scraper 41.
[0023] The inner walls of the adhesive scraper 4, the residual adhesive scraper 41, and the preparatory scraper 42 are all fitted with locking positioning strips 43, and the two ends of the locking positioning strips 43 are fixedly connected to the inner walls of both sides of the dissolving liquid holding tank plate 2. By setting the locking positioning strips 43, the adhesive scraper 4, the residual adhesive scraper 41, and the preparatory scraper 42 can be installed and positioned.
[0024] An extraction pipe 5 is installed inside the dissolving liquid holding tank plate 2, and a delivery pipe 51 is installed inside the dissolving liquid holding tank plate 2. The extraction pipe 5 is connected to an external extraction pump body, and the delivery pipe 51 is connected to a dissolving liquid storage tank and another extraction pump body. The dissolving liquid with reduced dissolving effect after use is extracted through the extraction pipe 5, and new dissolving liquid is injected into the dissolving liquid holding tank plate 2 through the delivery pipe 51.
[0025] A circulation support belt 6 is installed on one side of the solution container plate 2. An absorbent cotton 61 is fixedly connected to the outer wall of the circulation support belt 6. The absorbent cotton 61 is attached to the adhesive circulation attachment belt 3. The circulation support belt 6 supports the absorbent cotton 61, and the absorbent cotton 61 wipes the liquid, dust and other impurities on the outer surface of the adhesive circulation attachment belt 3 to avoid the adhesive circulation attachment belt 3 contacting the material plate and causing indentations on the surface of the material plate.
[0026] The working principle and usage process of this utility model are as follows: Before applying the adhesive, the material board is installed on the top of the material board positioning plate 1. The side wall of the material board is attached to the adhesive circulation belt 3. During the adhesive application process, the adhesive brush first contacts the top surface of the adhesive circulation belt 3. After reaching the predetermined starting position, the adhesive brush is squeezed and deformed, moving towards the material board. When passing the edge of the material board, the adhesive circulation belt 3 squeezes and seals the side wall of the material board, while simultaneously intercepting the bottom end of the adhesive brush and the adhesive. Furthermore, by setting a rounded chamfer 22, a small gap is left between the adhesive circulation belt 3 and the edge of the material board and the top of the side wall of the material board, so that the adhesive brush can neatly apply adhesive to the top of the side wall of the material board, and the adhesive will not overflow randomly onto the material board. The side wall surface of the material plate is covered with adhesive to ensure that the adhesive completely covers the top of the material plate. Due to the inaccuracy of the equipment, the adhesive brush cannot accurately start applying adhesive from the top edge of the material plate. After the adhesive application is completed, the drive roller 32 drives the adhesive circulation belt 3 to rotate counterclockwise, so as to move the adhesive-covered adhesive circulation belt 3 into the dissolving liquid holding tank plate 2 and immerse it in the dissolving liquid held in the dissolving liquid holding tank plate 2 to dissolve the adhesive on the surface of the adhesive circulation belt 3. The adhesive layer scraper 4 and the residual adhesive scraper 41 clean the adhesive on the surface of the adhesive circulation belt 3 and remove the adhesive from the surface of the adhesive circulation belt 3. Different parts of the adhesive circulation belt 3 circulate and limit the adhesive brush and overflow adhesive near the side wall of the material plate.
