Description

TECHNICAL FIELD

[0001] The present application relates to the field of anti-static table mat processing, in particular to a table mat anti-static coating device. BACKGROUND

[0002] The anti-static table mat is designed for laying on the workbench, and its core function is to effectively guide the static electricity accumulated on the workbench to the ground, so as to ensure that the static electricity does not cause damage to the electrical components during processing on the workbench, and to ensure smooth processing flow. In order to ensure that the anti-static table mat is stable and does not shift, it needs to be firmly bonded to the workbench. There are two feasible solutions for this bonding process: one is to turn the anti-static table mat upside down, with its bottom surface facing up, and then lay double-sided adhesive tape on the workbench to fix the table mat; the second is to pre-coat the back of the table mat with glue and cover it with a non-stick paper protective layer before it leaves the factory. When in use, simply tear off the non-stick paper and you can directly paste the table mat on the workbench.

[0003] In the process of coating glue, professional equipment is needed. Usually, this process is achieved by a glue roller, and there are two ways to apply glue to the glue roller: one is to use a system composed of a glue pump, a storage container and a spray head to supply glue; the other is to directly pour glue into the storage cavity in direct contact with the glue roller, and use the glue carried by the rotating glue roller to evenly coat the anti-static table mat.

Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present application, and should not be considered as the whole or as a limitation or restriction on the technical solution of the present application.

[0020] According to an embodiment of the present application, the technical solution is combined with Figures 1-5 It is shown.

[0021] A kind of platform pad anti-static coating device, its specific structure is as follows: The device includes container 1, container 1 is jointly constituted by storage tank and the vertical column for providing support function by bolt stable fixation outside storage tank. On both sides of container 1, symmetrically welded fixed baffle 2, the baffle 2 of one side adopts transparent material, such as transparent plastic, to facilitate observation inside.

[0022] Baffle 2 is rotatably installed with rubber roller 8 by bearing, and at the same time, first power part 5 is fixed on baffle 2 by the cooperation of mounting bracket and bolt. The function of first power part 5 is to drive rubber roller 8 to rotate, and the first power part 5 here selects motor, and the output end of motor is tightly fixed with rubber roller 8 through shaft coupling, so as to realize the stable rotation of rubber roller 8.

[0023] On the top of rubber roller 8, extrusion mechanism is installed, and its function is to extrude platform pad, so that it is more closely close to rubber roller 8. On one side of container 1, scraping mechanism is arranged for scraping excess glue on rubber roller 8. In addition, a box body 4 is welded and fixed on one side of container 1, the box body 4 is connected with the inside of container 1 close to one side of container 1, and the top is in open state, which is convenient for adding glue to the inside of container 1.

[0024] The bottom of the container 1 is slidably provided with a U-shaped plate 3, the outer side wall of the U-shaped plate 3 is tightly fitted on the inner side wall of the container 1, which is used to scrape off the glue on the inner side wall of the container 1, and the stored glue is located on the top of the U-shaped plate 3. At the bottom of the container 1, a second power part 7 is installed through the cooperation of a mounting frame and a bolt, and the second power part 7 is responsible for driving the U-shaped plate 3 to move inside the container 1. The second power part 7 can be selected as a hydraulic rod, and an electric push rod is preferred for simplifying the structure, and the telescopic end at the top of the electric push rod is fixed on the bottom of the U-shaped plate 3 through a bolt. At the same time, a through slot 6 is also provided at the bottom of the container 1, which is used to balance the air pressure between the bottom of the U-shaped plate 3 and the bottom end inside the container 1.

[0025] In actual operation, the glue is injected into the container 1, the first power part 5 drives the glue roller 8 to rotate, so that the glue is attached to the outer side of the glue roller 8, and then is applied to the pad. When it is necessary to prevent the glue from depositing, the second power part 7 is driven to lift the U-shaped plate 3, so that the glue at the bottom is lifted to the glue roller 8; when it is necessary to increase the glue storage space, the second power part 7 is driven to lower the U-shaped plate 3.

[0026] The extrusion mechanism in the embodiment has the following specific structure: a positioning rod 12 is welded and fixed on the top of one side baffle 2, and a sliding block 22 is slidably installed on the positioning rod 12; a first sleeve 13 is welded and fixed on the other side baffle 2; a first screw rod 9 is slidably installed in the first sleeve 13; a rotating block is welded and fixed on the top of the first screw rod 9, which is used to rotate the first screw rod 9; a sleeve block 10 is threadedly sleeved on the outside of the first screw rod 9, and the sleeve block 10 and the sliding block 22 are both circular; a compression roller 11 is rotatably installed between the sleeve block 10 and the sliding block 22 through a bearing; in addition, a limiting assembly is installed between the first screw rod 9 and the first sleeve 13, which is used to prevent the first screw rod 9 from moving axially.

[0027] The limiting assembly has the following specific structure: a second sleeve 19 is welded and fixed on the top of the first sleeve 13, the first screw rod 9 penetrates into the first sleeve 13 after being movably penetrated through the second sleeve 19, and the outer diameter and the inner diameter of the second sleeve 19 are both larger than the outer diameter and the inner diameter of the first sleeve 13; a limiting ring 14 is welded and fixed on the outside of the first screw rod 9, and the limiting ring 14 cooperates with the second sleeve 19. In use, the pad is sent into the space between the compression roller 11 and the glue roller 8, the pad is pressed on the glue roller 8 by the compression roller 11, the sleeve block 10 is moved downward along the first screw rod 9 by rotating the first screw rod 9, and at the same time, the sliding block 22 is synchronously moved downward along the positioning rod 12, so that the distance between the compression roller 11 and the glue roller 8 is adjusted, and the pad with different thicknesses is conveniently extruded.

[0028] The scraping mechanism in the embodiment is specifically configured as follows: a groove 15 is formed in the side of the container 1, and a scraper 16 is slidingly installed in the groove 15; a second screw rod 17 is fixedly welded on the side of the scraper 16 away from the rubber roller 8, and the second screw rod 17 extends to the outside of the container 1 after penetrating through the groove 15; a protrusion 18 is fixedly welded on the outside of the container 1, and the protrusion 18 is composed of two circular blocks, one of which has a larger outer diameter than the other; the second screw rod 17 penetrates through the protrusion 18; a movable block 20 is movably sleeved on the outside of the protrusion 18; a threaded hole 21 is formed in the center of the side of the movable block 20 away from the container 1; the second screw rod 17 penetrates through the threaded hole 21 by screwing, and moves along the inside of the threaded hole 21 when the movable block 20 rotates; a scale line is drawn on the top of the scraper 16, the numbers on the side of the scale line away from the rubber roller 8 are smaller, and the numbers on the side of the scale line close to the rubber roller 8 are larger, so as to facilitate accurate control of the amount of scraped glue.

[0029] Working principle: in use, first, the glue is poured into the inside of the box body 4 through the top opening thereof. Under the action of gravity, the glue naturally flows into the container 1 connected thereto.

[0030] Then, the pad to be glued is sent to the preset position between the rubber roller 8 and the pressure roller 11. Subsequently, the first screw rod 9 is rotated, and since the sliding block 22 is limited by the positioning rod 12 and can only move up and down, the sleeve block 10 cannot rotate with the first screw rod 9, but rotates relative to the first screw rod 9. The relative rotation causes the sleeve block 10 to move axially along the first screw rod 9 and synchronously drive the pressure roller 11 to move, until the pressure roller 11 is tightly pressed on the top of the pad, so as to accurately position the pad. This step ensures that the glue can be accurately applied to the lower end of the pad in the subsequent gluing process.

[0031] Next, the movable block 20 is rotated, and since the second screw rod 17 is fixed and cannot rotate with the movable block 20, the movable block 20 and the second screw rod 17 rotate relative to each other. The rotation causes the second screw rod 17 to move axially along the movable block 20 through the threaded hole 21, and further drive the scraper 16 to slide in the groove 15. By adjusting the position of the scraper 16, the distance between the scraper 16 and the rubber roller 8 can be accurately controlled, and the specific movement value can be read through the scale line on the scraper 16, so as to make fine adjustment.

[0032] After that, the motor is started to drive the rubber roller 8 to rotate. The rubber roller 8 adheres the glue in the container 1 to its outer surface during rotation, and moves to the scraper 16. After the scraper 16 scrapes the excess glue on the surface of the rubber roller 8, the remaining glue continues to move to the top of the rubber roller 8 and is applied to the lower end of the pad. At the same time, the rotating rubber roller 8 also drives the pad to move, so that the uncoated part is sequentially moved to the coating position, until the lower end of the pad is uniformly coated with glue.

[0033] As the adhesive application process continues, the amount of adhesive inside container 1 gradually decreases. At this point, the remaining amount of adhesive can be observed through the transparent baffle 2. When the adhesive depth is below half the position of the glue roller 8, the electric push rod is activated to drive the U-shaped plate 3 to move upward inside container 1, thereby raising the adhesive position and ensuring that the glue roller 8 can continuously pick up adhesive until the adhesive is completely used.

[0034] When glue needs to be added, the electric push rod is activated to retract, driving the U-shaped plate 3 downward to expand the volume of container 1. Then, new glue is filled into container 1 through the box 4 to continue the glue application process.

[0035] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
