Description

Technical Field

[0001] This utility model relates to the field of adhesive scraping technology, and in particular to an adhesive scraping device. Background Technology

[0002] In automated dispensing processes, adhesive residue often remains on the nozzle after dispensing. If this residue is not cleaned promptly, it can lead to nozzle clogging, reduced dispensing accuracy, and even affect the quality of subsequent dispensing. The adhesive scraper plays a crucial role in dispensing equipment, effectively removing residual adhesive from the nozzle and ensuring the stability and consistency of the dispensing process.

[0003] While existing glue scraping methods have improved scraping efficiency to some extent, their functions are relatively limited and they cannot flexibly adjust the position of the glue head. When dealing with glue heads of different shapes, sizes, and dispensing positions, it is difficult to ensure effective cleaning of all areas in the circumference of the glue head, which can easily create glue scraping dead corners. As a result, some residual glue cannot be completely removed, leading to inconsistent cleaning effects on the glue head and affecting the stability of dispensing quality.

[0004] Therefore, there is an urgent need for a scraping device that can scrape adhesive in multiple directions and increase the cleaning contact area to improve scraping efficiency and cleaning effect. Utility Model Content

[0015] Compared with the prior art, the present invention provides a glue scraping device, which has the following beneficial effects:

[0016] 1. The multi-axis moving component first drives the adhesive head to slide back and forth along one side of the cleaning cloth, scraping off the adhesive on the adhesive head by the relative sliding between the cleaning cloth and the adhesive head. Then, it drives the adhesive head to slide back and forth along the other side of the cleaning cloth to scrape off the adhesive again. During the scraping process, the multi-axis moving component can also drive the adhesive head to move in the back and forth direction, so that the adhesive head applies a pushing force to the side of the cleaning cloth, causing the side of the cleaning cloth to bend under force, thereby increasing the contact area between the cleaning cloth and the adhesive head. This ensures that the adhesive in different areas in the circumference of the adhesive head is effectively scraped off by the cleaning cloth, greatly reducing the dead angles of the adhesive scraping and significantly improving the adhesive scraping effect.

[0017] 2. The spring force ensures that the cleaning cloth remains taut during the winding process. This stable tension allows the cleaning cloth to make better contact with the adhesive head when applying the adhesive, preventing loosening or wrinkling and ensuring smooth adhesive application.

[0018] 3. The multi-axis moving assembly consists of a front-to-back moving mechanism, a left-to-right moving mechanism, and an electric telescopic rod. The front-to-back moving mechanism drives the slider one to move via an electric slide rail one, the left-to-right moving mechanism drives the slider two to move via an electric slide rail two, and the electric telescopic rod directly drives the glue head to move. This allows the glue head to be flexibly adjusted in the X, Y, and Z axes. During dispensing operations, the glue head can be precisely adjusted to the appropriate position according to different dispensing needs to achieve accurate dispensing. During scraping operations, the glue head can also be easily moved above the cleaning cloth and scraped in different directions and angles.

[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] A scraping device, such as Figures 1 to 4As shown, the device includes a base 1, a scraping assembly for scraping glue from a glue head 8 is installed on the top outer wall of the base 1, a multi-axis moving assembly is installed on the top outer wall of the base 1, and the glue head 8 is installed on the multi-axis moving assembly. The scraping assembly includes a mounting base 10, a winding mechanism one and a winding mechanism two, and the mounting base 10 is fixed to the top outer wall of the base 1 by bolts. The winding mechanism one and the winding mechanism two are rotatably connected to the top of the mounting base 10, and a cleaning cloth 9 is wound between the winding mechanism one and the winding mechanism two.

[0027] The position of the glue head 8 can be adjusted in the X, Y and Z axis directions using the multi-axis moving component, so as to achieve flexible adjustment of the position of the glue head 8. The glue head 8 can be used to perform glue dispensing operations. Glue dispensing is an existing technology, and its process and principle will not be described in detail here.

[0028] After the dispensing head 8 completes the dispensing operation, adhesive residue will remain on its head. To ensure the normal use of the dispensing head 8 in the future, it is necessary to scrape off the adhesive residue from its head. During scraping, a multi-axis moving component drives the dispensing head 8 to move above the cleaning cloth 9 wound between the winding mechanism one and the winding mechanism two. The cleaning cloth 9 is vertically positioned at this time. During scraping, the multi-axis moving component drives the dispensing head 8 to slide back and forth along one side of the cleaning cloth 9. Utilizing the relative sliding and friction between the cleaning cloth 9 and the dispensing head 8, the adhesive residue on the dispensing head 8 is scraped off by the cleaning cloth 9. The scraped-off adhesive residue adheres to the cleaning cloth 9. To reduce dead zones during scraping, when the dispensing head 8 moves along the cleaning cloth 9... After the cloth 9 slides back and forth on one side to scrape off the adhesive, the multi-axis moving component drives the glue head 8 to slide back and forth along the other side of the cleaning cloth 9, so that the other side of the cleaning cloth 9 scrapes the glue head 8 again. The purpose of this is to ensure that the adhesive in different areas of the glue head 8 in the circumferential direction can be scraped off by the cleaning cloth 9. At the same time, during the scraping process, the multi-axis moving component can also drive the glue head 8 to move in the back and forth direction. When the glue head 8 moves back and forth, it will apply a pushing force to the side of the cleaning cloth 9. The side of the cleaning cloth 9 bends after being subjected to the force, thereby increasing the contact area between the cleaning cloth 9 and the glue head 8 and ensuring the scraping effect.

[0029] The multi-axis moving assembly includes a front-back moving mechanism and a left-right moving mechanism. The front-back moving mechanism includes a support frame 2 and an electric slide rail 3. The support frame 2 is fixed to the top outer wall of the base 1 by bolts, and the electric slide rail 3 is fixed to the top of the support frame 2 by bolts. The electric slide rail 3 is slidably connected to a slider 4. The left-right moving mechanism includes an electric slide rail 5 and a slider 7. The electric slide rail 5 is fixed to one side outer wall of the slider 4 by bolts, and the slider 7 and the electric slide rail 5 are slidably connected. The multi-axis moving assembly also includes an electric telescopic rod 6. The electric telescopic rod 6 is fixed to the top outer wall of the slider 7 by bolts, and the output end of the electric telescopic rod 6 is fixedly connected to the rubber head 8.

[0030] The electric slide rail 3 can drive the slider 4 to move, the electric slide rail 5 can drive the slider 7 to move, and the electric telescopic rod 6 can drive the rubber head 8 to move, thereby realizing the position adjustment of the rubber head 8 in the X, Y and Z axis directions.

[0031] The winding mechanism includes a placement seat 12, a ribbed insert rod 13, and a rotating shaft 20. The rotating shaft 20 is rotatably connected to the top of the mounting seat 10, and the placement seat 12 is welded to the top of the rotating shaft 20. The ribbed insert rod 13 is welded to the top of the placement seat 12, and a winding cylinder 11 is slidably connected to the outer wall of the ribbed insert rod 13.

[0032] The cleaning cloth 9 can be wound using the winding drum 11. The rib-shaped insert 13 and the winding drum 11 are slidably connected. The winding drum 11 can be installed using the rib-shaped insert 13.

[0033] The second winding mechanism includes a second rib-shaped insert rod 15, a second placement seat 17, and a second rotating shaft 21. The second rotating shaft 21 is rotatably connected to the top outer wall of the mounting base 10, and the second placement seat 17 is welded to the top outer wall of the second rotating shaft 21. The second rib-shaped insert rod 15 is welded to the top outer wall of the second placement seat 17. A self-locking motor 18 is fixed to the top inner wall of the mounting base 10 by bolts, and the output end of the self-locking motor 18 is connected to the bottom of the second rotating shaft 21 by a coupling. A second winding cylinder 14 is slidably connected to the outer wall of the second rib-shaped insert rod 15.

[0034] The self-locking motor 18 can drive the ribbed insert 15 to rotate, and the ribbed insert 15 and the winding drum 14 can rewind the used cleaning cloth 9 during the rotation.

[0035] A coil spring 19 is installed between the outer circumference of the rotating shaft 20 and the top outer wall of the mounting base 10;

[0036] The spring force of the coil spring 19 is used to ensure that the cleaning cloth 9 is kept taut during the rolling process.

[0037] A guide assembly is installed on the top outer wall of the mounting base 10. The guide assembly includes two sets of guide rollers 16, and the guide rollers 16 are rotatably connected to the top of the mounting base 10.

[0038] In this embodiment, the number of guiding components is preferably two sets. By placing the cleaning cloth 9 between two guide rollers 16, the guide rollers 16 can guide the movement path of the cleaning cloth 9.

[0039] Working principle: In the multi-axis moving assembly, the electric slide rail 3 drives the slider 4 to move back and forth, the electric slide rail 5 drives the slider 7 to move left and right, and the electric telescopic rod 6 drives the dispensing head 8 to move up and down. Through these three directions of movement, the dispensing head 8 is precisely adjusted to the required position for dispensing, so as to achieve flexible positioning of the dispensing head 8 in the X, Y, and Z axes. After adjusting the position of the dispensing head 8, the dispensing operation is performed using the dispensing head 8. When scraping is required, the winding drum 11 with the cleaning cloth 9 is slidably installed onto the ribbed insert rod 13, and the empty winding drum 14 is slid... Installed onto the ribbed insert rod 15, the cleaning cloth 9 is led out from the winding drum 11, guided between two sets of guide rollers 16, and then wound onto the winding drum 14. The cleaning cloth 9 is kept taut by the spring 19 installed between the outer circumference of the rotating shaft 20 and the top outer wall of the mounting base 10. After the dispensing operation is completed, adhesive residue adheres to the head of the dispensing head 8. The multi-axis moving assembly then drives the dispensing head 8 to move above the cleaning cloth 9 wound between the winding mechanism 1 and the winding mechanism 2. The multi-axis moving assembly drives the dispensing head 8 along the cleaning cloth... The cleaning cloth 9 slides back and forth on one side, and the relative sliding between the cleaning cloth 9 and the adhesive head 8 scrapes off the adhesive adhering to the adhesive head 8. The scraped adhesive adheres to the cleaning cloth 9. During the scraping process, the multi-axis moving component also drives the adhesive head 8 to move in the back-and-forth direction. When the adhesive head 8 moves back and forth, it applies a pushing force to the side of the cleaning cloth 9. The side of the cleaning cloth 9 bends under the force, thereby increasing the contact area between the cleaning cloth 9 and the adhesive head 8 to ensure the scraping effect. The adhesive head 8 slides back and forth along one side of the cleaning cloth 9 to apply adhesive. After the liquid is scraped off, the multi-axis moving component drives the glue head 8 to slide back and forth along the other side of the cleaning cloth 9, and uses the other side of the cleaning cloth 9 to scrape the glue head 8 again, ensuring that the glue in different areas of the glue head 8 in the circumferential direction can be scraped off by the cleaning cloth 9. During or after the glue scraping operation, the self-locking motor 18 on the top outer wall of the mounting base 10 is started. The self-locking motor 18 can drive the rib-shaped insert rod 15 to rotate. The rib-shaped insert rod 15 and the winding drum 14 can rewind the used cleaning cloth 9 during synchronous rotation.
