[0045] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0046] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0047] Figure 1 , Figure 2 and Figure 3 A schematic diagram of an automatic paint coating mechanism according to an embodiment of the present invention is shown. As shown, the automatic paint coating mechanism includes: a coating platform 1, a first linear module 3, a second linear module 6, a third linear module 7, a fourth linear module 11, a fifth linear module 12, an extrusion head 8, and a scraper 13;

[0048] The scraping platform 1 is used to place the scraping tray 2 or the waterproof coating scraping base plate 17;

[0049] A first linear module 3 is installed below the coating platform 1, which enables the coating platform 1 to move longitudinally.

[0050] A second linear module 6 is installed on the first linear module 3, and a third linear module 7 is installed on the second linear module 6. The second linear module 6 enables the third linear module 7 to move laterally. A squeezing head 8 is installed on the third linear module 7 and a syringe 10 is placed thereon. The syringe 10 is located directly below the squeezing head 8. The third linear module 7 enables the squeezing head 8 to move up and down and squeeze the syringe 10.

[0051] A fourth linear module 11 is installed on the first linear module 3, and a fifth linear module 12 is installed on the fourth linear module 11. The fourth linear module 11 enables the fifth linear module 12 to move laterally. A scraper 13 is installed on the fifth linear module 12, and the fifth linear module 12 enables the scraper 13 to move up and down.

[0052] According to an embodiment of the present invention, a mounting base plate 4 is mounted on the first linear module 3, and upright plates 5 are respectively mounted on both sides of the mounting base plate 4. The second linear module 6 and the fourth linear module 11 are mounted on the upright plates 5. That is, the second linear module 6 and the fourth linear module 11 are mounted on the first linear module 3 through the upright plates 5 and the mounting base plate 4, so that the first linear module 3 can carry the second linear module 6 and the fourth linear module 11 for longitudinal movement. Further, the third linear module 7 mounted on the second linear module 6, as well as the extrusion head 8 and syringe 10 on the third linear module 7, can be moved longitudinally through the first linear module 3. The fifth linear module 12 mounted on the fourth linear module 11, as well as the scraper 13 mounted on the fifth linear module 12, can be moved longitudinally through the first linear module 3.

[0053] According to an embodiment of the present invention, a syringe fixture 9 is mounted on the third linear module 7, and the syringe 10 is placed on the syringe fixture 9. The syringe fixture 9 is located directly below the extrusion head 8. When the third linear module 7 moves the extrusion head 8 downward, the extrusion head 8 can squeeze the syringe placed on the syringe fixture 9, causing the syringe to output paint or waterproof coating. Furthermore, the third linear module 7 can move laterally along the second linear module 6, allowing the syringe 10 to move laterally. Therefore, the syringe 10 can move longitudinally via the first linear module 3 and laterally via the second linear module 6, allowing the syringe 10 to move to a set position on the coating platform 1, for example, above the coating tray 2 or the waterproof coating base plate 17.

[0054] According to an embodiment of the present invention, a fifth linear module 12 is mounted on the fourth linear module 11, and a scraper 13 is mounted on the fifth linear module 12. The fifth linear module 12 can move laterally along the fourth linear module 11, allowing the scraper 13 to move laterally as well. Therefore, the scraper 13 can move laterally via the fourth linear module 11 and longitudinally via the first linear module 3, allowing the scraper 13 to move to a set position on the coating platform 1, for example, above the coating tray 2 or the waterproof coating base plate 17. Furthermore, the scraper 13 can move up and down via the fifth linear module 12, for example, the scraper 13 can move downwards to press the wire bar or preparation device on the coating tray 2 or the waterproof coating base plate 17.

[0055] Figure 4a and Figure 4b A schematic diagram of a fifth linear module according to an embodiment of the present invention is shown. As shown, the fifth linear module 12 includes a stepper motor 1101, a lead screw nut 1103, a spring 1105, a ball bearing 1106, and a scraper mounting plate 1110. When the scraper 13 moves downward in the fifth linear module 12, the stepper motor 1101 rotates, causing the lead screw nut 1103 to descend and compress the spring 1105, thereby pushing the ball bearing 1106 and the scraper mounting plate 1110 downward, causing the scraper 13 to move downward.

[0056] According to an embodiment of the present invention, the stepper motor 1101 is mounted on the mounting plate 1102. The output end of the stepper motor 1101 is connected to the lead screw nut 1103, and the lead screw nut 1103 is connected to the T-shaped lead screw 1104. The T-shaped lead screw 1104 presses one end of the spring 1105, and the other end of the spring 1105 presses the ball bearing 1106. The ball bearing 1106 is connected to the scraper mounting plate 1110 via a connecting rod 1107. To ensure that the movement direction of the scraper mounting plate 1110 is linear, the movement direction of the scraper mounting plate 1110 can be restricted by the spring 1108 and the guide clamp 1109. Furthermore, the fifth linear module can be mounted on the fourth linear module 11 via the mounting plate 1111, the connecting plate 1113, and the connecting plate 1114, and the fifth linear module can be guided to perform linear movement in the up and down direction via the linear guide rail 1112. The buffer mounting plate 1115 can be flexibly connected to the scraper mounting plate 1110, for example, through a spring 1108. Furthermore, the spring 1105 can also flexibly connect the scraper 13 to the fifth linear module 12. During the scraper 13's movement, if it encounters an obstacle, the flexible connection allows the scraper 13 to pass smoothly, making the scraping process smoother. The spring's performance coefficient can be predetermined; by driving the lead screw nut 1103 down via the stepper motor 1101, the compression of the spring 1105 can be controlled, thereby controlling the pressure of the scraper 13 on the wire rod or preparation device, i.e., the scraping force can be precisely controlled. Furthermore, the scraping force is related to the coating thickness; for example, the greater the scraping force, the thinner the coating. Therefore, the coating thickness can be precisely controlled by controlling the scraping force. This correlation between scraping force and coating thickness can be experimentally measured, and the present invention does not limit this correlation.

[0057] According to an embodiment of the present invention, a sixth linear module 14 is mounted on the upright plate 5. The sixth linear module 14 is equipped with a defoaming mechanism 15, which enables the defoaming mechanism 15 to move vertically. In this example, the defoaming mechanism 15 includes a Teflon film, which can be used to scrape across the coating to remove bubbles from the coating. The defoaming mechanism 15 may also include a mounting plate 20, on which the Teflon film can be mounted. The mounting plate 20 can be mounted on the sixth linear module 14, allowing the Teflon film to move vertically through the sixth linear module. The present invention does not limit the device for scraping across the coating to remove bubbles; that is, other films besides Teflon films can also be used for defoaming treatment.

[0058] According to an embodiment of the present invention, the distance between the Teflon film and the paint film / waterproof coating film can be precisely controlled by the sixth linear module 14, ensuring good defoaming effect without damaging the paint film / waterproof coating film. The height the Teflon film descends is equal to the total height (the initial position of the Teflon film from the coating platform) minus the thickness of the tray and the paint film / waterproof coating film.

[0059] According to embodiments of the present invention, after applying a waterproof coating, a Teflon film is typically used for defoaming. A film cleaning mechanism 16 is installed at the end of the coating platform 1. The film cleaning mechanism 16 includes two opposing rotating brush rollers, which are used to clean the waterproof coating on the Teflon film when it enters the film cleaning mechanism 16. That is, after defoaming with the Teflon film, the Teflon film may still have waterproof coating adhering to it, which can be cleaned by the brush rollers of the film cleaning mechanism 16. Of course, after applying paint, a Teflon film can also be used for defoaming, and after defoaming, the paint on the Teflon film can also be removed by the film cleaning mechanism 16.

[0060] According to an embodiment of the present invention, during the coating process, one or more test plates can be placed on the coating tray 2, and the test plates can be coated with paint. A release liner 18 can be placed on the waterproof coating base plate 17, and the release liner 18 is coated with waterproof paint. Furthermore, a clamping cylinder 19 is installed on the coating platform 1, and the release liner 18 is placed on the waterproof coating base plate 17; the clamping cylinder 19 is used to clamp the release liner 18.

[0061] According to an embodiment of the present invention, the process of applying paint to multiple test plates on a scraping tray 2 is first described. The automatic paint scraping mechanism is used as follows: when applying paint, a wire bar or preparation device is placed on the test plate on the scraping tray 2; the first linear module 3 moves longitudinally, and the fourth linear module 11 simultaneously moves laterally, causing the scraper to move directly above the wire bar or preparation device; the fifth linear module 12 causes the scraper 13 to move downwards, pressing down on the wire bar or preparation device; the second linear module 6 moves laterally, causing the syringe 10 to move above the test plate; the second linear module 6 moves laterally within a lateral range above the test plate, and the third linear module 7 simultaneously causes the extrusion head 8 to move downwards, causing the syringe 10 to output paint; the first linear module 3 moves longitudinally, causing the scraper 13 to press down on the wire bar or preparation device and move longitudinally on the test plate to scrape the test plate; after the test plate is scraped, the wire bar or preparation device is retrieved and sent to a cleaning device.

[0062] According to an embodiment of the present invention, a robot can select the bar or preparer corresponding to the first test plate on the coating tray 2, and pick it up from the bar preparer storage area and place it on the first test plate on the coating tray 2. The first linear module 3 and the fourth linear module 11 can move simultaneously, so that the scraper 13 moves directly above the bar or preparer, and the stepper motor 1101 of the fifth linear module 12 can drive the scraper 13 to press down, so that the groove of the scraper 13 presses the bar or preparer with a preset force.

[0063] According to an embodiment of the present invention, the second linear module 6 moves the syringe 10 above the first test plate, and the third linear module 7 moves downward, causing the extrusion head 8 to move downward and extrude the syringe 10, thus outputting paint coating. Simultaneously, the second linear module 6 moves laterally back and forth, causing the paint coating to be output linearly back and forth within the lateral movement range of the second linear module 6. Furthermore, due to the longitudinal movement of the first linear module 3, when the linearly back and forth output paint lands on the first test plate, it forms an S-shape on the first test plate. At the same time, due to the longitudinal movement of the first linear module 3 and the pressing action of the scraper 13 on the wire rod or preparer, the wire rod or preparer scrapes the S-shaped paint onto the first test plate until the first test plate is completely coated.

[0064] According to an embodiment of the present invention, the shape of the paint output to the test plate can be controlled by the cooperation of the first linear module 3 and the second linear module 6. Furthermore, in order to obtain a better scraping effect, the shape of the paint output to the test plate can be S-shaped, W-shaped, M-shaped, stepped, wave-shaped, etc.

[0065] According to an embodiment of the present invention, after the first test plate is coated, the wire bar or preparation device can be recovered and sent to the cleaning equipment for later use. The wire bar or preparation device is not fixed on the scraper, which facilitates the selection, replacement and cleaning of the wire bar or preparation device.

[0066] According to an embodiment of the present invention, after the first test plate is coated and the wire bar or preparer is retrieved, the wire bar or preparer for the second test plate can be selected in a similar manner and placed on the second test plate. The coating process for the second test plate, and the retrieval of the wire bar or preparer after coating, are similar to those for the first test plate and will not be described again here. After all test plates on the coating tray 2 have been coated, the coating process is complete, the automatic paint coating mechanism can be returned to its original position, and the coating tray can be removed.

[0067] According to an embodiment of the present invention, in the case where there are multiple test plates in the coating tray, the syringe 10 can be precisely positioned to the tray to be coated by the cooperation of the first linear module 3 and the second linear module 6.

[0068] According to an embodiment of the present invention, the following describes the process of applying a waterproof coating to release paper 18. The automatic coating mechanism is used to: place the release paper on the waterproof coating base plate 17 and clamp the release paper 18 using a clamping cylinder 19 when applying the waterproof coating; place a wire rod or a preparation device on the release paper 18; the first linear module 3 moves longitudinally, and the fourth linear module 11 moves laterally to move the scraper to directly above the wire rod or preparation device; the fifth linear module 12 moves the scraper 13 downward to press it down. The first linear module 3 moves laterally, causing the syringe 10 to move above the release paper 18; the second linear module 6 moves laterally within a lateral range above the release paper, while the third linear module 7 simultaneously moves the extrusion head 8 downward, causing the syringe 10 to output waterproof coating; the first linear module 3 moves longitudinally, causing the scraper 13 to press the linear module or preparer onto the release paper and move longitudinally to coat the release paper 18; after the release paper is coated, the linear module or preparer is retrieved and sent to a cleaning device.

[0069] According to an embodiment of the present invention, as described above, the release paper 18 can be clamped by the clamping cylinder 19, thereby preventing the release paper 18 from sliding relative to the waterproof coating base plate 17.

[0070] According to an embodiment of the present invention, the release paper can be coated multiple times through the above steps. A robot can select the wire bar or preparation device required for the first coating and pick it up from the wire bar preparation device storage area and place it on the release paper 18. The first linear module 3 and the fourth linear module 11 can move simultaneously, so that the scraper 13 moves directly above the wire bar or preparation device. The stepper motor 1101 of the fifth linear module 12 can drive the scraper 13 to press down, so that the groove of the scraper 13 presses the wire bar or preparation device with a preset force.

[0071] According to an embodiment of the present invention, the second linear module 6 moves the syringe 10 above the release paper 18, and the third linear module 7 moves downward, causing the extrusion head 8 to move downward and extrude the syringe 10, thus dispensing the waterproof coating. Simultaneously, the second linear module 6 moves laterally back and forth, causing the waterproof coating to be dispensing in a linear, reciprocating pattern within the lateral movement range of the second linear module 6. Furthermore, due to the longitudinal movement of the first linear module 3, the linearly dispensing waterproof coating, when it lands on the release paper 18, forms an S-shape on the release paper 18. At the same time, due to the longitudinal movement of the first linear module 3 and the pressing action of the scraper 13 on the wire rod or preparer, the wire rod or preparer scrapes the S-shaped waterproof coating onto the release paper 18 until the first scraping is completed.

[0072] According to an embodiment of the present invention, the shape of the waterproof coating output onto the release paper can be controlled by the cooperation of the first linear module 3 and the second linear module 6. Furthermore, in order to obtain a better coating effect, the shape of the waterproof coating output onto the release paper can be S-shaped, W-shaped, M-shaped, stepped, wave-shaped, etc.

[0073] According to an embodiment of the present invention, after the first coating is completed, the wire bar or preparation device can be recovered and sent to a cleaning device for future use. The wire bar or preparation device is not fixed to the scraper, which facilitates the selection, replacement and cleaning of the wire bar or preparation device.

[0074] According to an embodiment of the present invention, after the first coating is completed and the bar or preparer is retrieved, the bar or preparer required for the second coating can be selected in a similar manner and placed on the release paper 18. The second coating process, as well as the retrieval of the bar or preparer after coating, is similar to the first coating process and will not be described again here.

[0075] According to an embodiment of the present invention, the automatic paint coating scraping mechanism is further configured to: move the first linear module 3 longitudinally so that the defoaming mechanism 15 moves to the foremost end of the waterproof coating on the release paper; move the sixth linear module 14 downward so that the defoaming mechanism 15 contacts the waterproof coating; and move the first linear module 3 longitudinally reciprocating so that the defoaming mechanism 15 scrapes the waterproof coating multiple times to remove air bubbles from the surface of the waterproof coating.

[0076] According to an embodiment of the present invention, when applying waterproof coating to release paper 18, air bubbles may be generated on the surface. To improve the coating effect, the waterproof coating on the surface of release paper 18 can be defoamed by defoaming mechanism 15. The first linear module 3 can move longitudinally to move the defoaming mechanism 15 to the foremost edge of the waterproof coating on the release paper, and the sixth linear module 14 can move downward to make the Teflon film of the defoaming mechanism 15 contact the waterproof coating. Then, the first linear module 3 can move longitudinally back and forth to make the Teflon film repeatedly scrape across the surface of the waterproof coating, thereby removing air bubbles from the waterproof coating. For example, the Teflon film can be repeatedly scraped across the surface of the waterproof coating three times to remove air bubbles.

[0077] According to an embodiment of the present invention, after the entire release paper 18 is coated and defoamed, the automatic paint coating mechanism can be restored to its original position and the waterproof coating base plate 17 can be removed.

[0078] According to the automatic paint coating mechanism of the present invention, the scraper and the wire bar or preparer are set separately. The scraper pushes the wire bar or preparer forward to scrape the paint. After the scraping is completed, the wire bar and the scraper are automatically separated. The robot takes away the wire bar for cleaning and replacement, which facilitates the selection, replacement and cleaning of the wire bar and preparer. Moreover, the scraper and the fifth linear module are flexibly connected. The elastic force can be controlled by controlling the compression of the spring 1105, thereby controlling the scraping force and making the scraping smoother. Furthermore, since the scraping force is related to the coating thickness, the coating thickness can be accurately controlled based on the scraping force, making the coating thickness more precise.

[0079] This invention employs a Teflon film to remove air bubbles during the coating process and uses a servo mechanism to drive each linear module, resulting in higher coating quality, fewer air bubbles, and more precise thickness control. In the automatic paint coating mechanism of this invention, the ordinary paint coating station can also be used to coat waterproof coatings.
