DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0023] Example 1

[0024] like Figures 1 to 3 As shown, this embodiment provides a vertical coating mechanism 2, including a driving mechanism 1 and two coating mechanisms 2, with a gap 3 between the two coating mechanisms 2, the driving mechanism 1 is used to drive the two coating mechanisms 2 to move closer to or away from each other, and also includes a clamping mechanism 4, the clamping mechanism 4 is located below the gap 3, the clamping mechanism 4 is used to clamp the vertically placed plate and drive the plate to move along the axial direction of the coating mechanism 2.

[0025] When the utility model is working, the loading mechanism lowers the vertically placed plate to pass through the gap 3, and is then clamped by the clamping mechanism 4. Subsequently, the clamping mechanism 4 moves according to the relative position of the plate and the coating mechanism 2 to adjust the position of the plate; the driving mechanism 1 controls the two coating mechanisms 2 to approach each other so that the two coating mechanisms 2 clamp the plate, and the coating mechanism 2 rotates to coat the plate while driving the plate to move upward; when the plate is clamped by the coating mechanism 2, the clamping mechanism 4 releases the plate to ensure that the plate will not be pulled, thereby ensuring the safety of the plate.

[0026] The utility model realizes the position adjustment of the plate before coating through the setting of the clamping mechanism 4, so that the plate and the coating mechanism 2 are reliably aligned, so that the length of the coating mechanism 2 can be reduced and reliable coating can still be achieved. At the same time, when it is necessary to leave blank space on both sides of the plate, it can also be achieved through alignment.

[0027] In this embodiment, the clamping mechanism 4 includes two clamping plate modules 41, the clamping plate module 41 includes a clamping plate driving member 42, a clamping plate transverse movement assembly 43 and two clamping plate assemblies 44, the clamping plate transverse movement assembly 43 is used to drive the clamping plate driving member 42 to move along the axial direction of the first coating mechanism 2, and the two clamping plate assemblies 44 are both installed on the clamping plate driving member 42, the clamping plate driving member 42 is used to drive the two clamps to move closer to or away from each other, and the two clamping plate assemblies 44 are used together to clamp the plate.

[0028] That is, when splinting, one of the splint modules 41 is required to splint, and then the splint module 41 is moved so that the other end of the panel extends into the other splint module 41, and the other splint module 41 is used to splint, thereby ensuring that the position of the panel clamped by the splint module 41 is not too deep.

[0029] Specifically, the clamping mechanism 4 also includes a plate identifier (not shown in the figure), which is used to identify the position of the plate that the clamping module 41 is about to clamp / has clamped. The plate identifier can be a conventional device such as a photoelectric switch or an infrared switch, which can be set at a corresponding position below the coating mechanism 2, and the number is preferably two or more. That is, after the bottom of the plate passes through the gap 3, a plate identifier can identify the plate, so a clamping module 41 will clamp the plate; then the clamping module 41 drives the plate to move horizontally, and after another plate identifier recognizes the plate, the clamping module 41 stops moving, and the other clamping module 41 clamps the other end of the plate, thereby achieving the effect of clamping the corresponding depth; then the two clamping modules 41 move horizontally in the same direction / speed until another plate identifier recognizes the plate, that is, the plate has reached the position and can be coated.

[0030] In this embodiment, the driving mechanism 1 includes a driving module 11, a first driving seat 12, a second driving seat 13, a first limiting member 14 and a second limiting member 15. The two coating mechanisms 2 are respectively installed on the first driving seat 12 and the second zone for movement. The driving module 11 is used to drive the first driving seat 12 and the second driving seat 13 to move closer to or away from each other; the first limiting member 14 and the second limiting member 15 are respectively installed on the first driving seat 12 and the second zone for movement. When the first limiting member 14 conflicts with the second limiting member 15, the first driving seat 12 and the second driving seat 13 are no longer close to each other.

[0031] The first limit member 14 and the second limit member 15, preferably one of which is a commonly used device such as a photoelectric switch or a proximity switch. Through the setting of the first limit member 14 and the second limit member 15, it is ensured that the first drive seat 12 and the second drive seat 13 stop moving every time they approach each other by a certain distance, thereby ensuring that the gap 3 between the two coating mechanisms 2 reaches the expected value to avoid pinching the plate.

[0032] Specifically, the drive module 11 includes a drive motor 111, a drive screw 112, and a drive nut 113. The drive nut 113 is disposed on the first drive base 12. The drive motor 111 drives and connects the drive screw 112, which is threadedly connected to the drive nut 113. The cooperation between the drive motor 111 and the screw-nut structure achieves high-precision and stable drive of the first drive base 12, ensuring that the first drive base 12 does not move excessively and cause safety accidents. In addition, the second drive base 13 does not move relative to the plate when the first drive base 12 moves, ensuring safety.

[0033] Specifically, the driving module 11 also includes a positioning cylinder 114, a positioning transmission member 115 and a positioning limit member 116. The positioning transmission member 115 is installed on the second driving seat 13. The positioning transmission member 115 is installed on the piston rod of the positioning cylinder 114. The positioning limit member 116 is used to interfere with the positioning transmission member 115 to limit the moving stroke of the positioning transmission member 115.

[0034] The arrangement of the position adjustment cylinder 114, the position adjustment transmission member 115 and the position adjustment limit member 116 mainly plays the following roles:

[0035] 1. Adjust the position of the position-adjusting limiter 116 to adjust the position of the second driving seat 13 and achieve the function of adaptive adjustment according to the thickness of the plate.

[0036] 2. Before the plate descends, the first drive seat 12 is driven backward by the drive motor 111, and the second drive seat 13 is driven backward by the positioning cylinder 114 to make enough space for the plate to descend; after the plate is clamped and adjusted by the clamping mechanism 4, the positioning cylinder 114 first drives the second drive seat 13 forward until the positioning transmission member 115 contacts the positioning limit member 116 so that the coating mechanism 2 of the second drive seat 13 contacts the plate, and then the drive motor 111 drives the first drive seat 12 close to the second drive seat 13, thereby making way for the loading plate and avoiding excessive clamping and wear of the plate.

[0037] In this embodiment, the coating mechanism 2 includes a coating roller 21, a coating rotation module 22, a coating holder 23, and a scraper module 24. The coating rotation module 22 is used to drive the coating roller 21 to rotate. The coating holder 23 is used to load the coating. The coating roller 21 is dipped in the coating holder 23 and applied to the plate. The coating roller 21 is used to contact the plate for coating and exert an upward driving force on the plate during the coating process.

[0038] When the plate rises and leaves the coating roller 21 , the scraping module 24 is used to scrape off excess coating at both ends of the bottom of the plate.

[0039] That is, during coating, the two coating rollers 21 rotate in opposite directions, applying the coating on the coating rollers 21 to the plate while simultaneously driving the plate upward. After the plate has risen to a certain position, an external robot grasps the plate and drives it to continue rising until it leaves the coating rollers 21. However, during the rising period, some coating slides down the plate under the action of gravity and accumulates at the bottom of the plate. At this time, the scraping mechanism scrapes off this excess coating, allowing the coating to fall back onto the coating rollers 21 / coating holder 23, achieving the effect of uniform coating at all positions on the plate.

[0040] Specifically, the coating mechanism 2 further includes a positioning module 25 , which is used to drive the coating roller 21 to move back and forth on the driving mechanism 1 .

[0041] For the coating mechanism 2 of the first drive seat 12, the positioning module 25 can drive the coating roller 21 to move slightly, so that after the first drive seat 12 and the second drive seat 13 no longer move relative to each other, the positioning module 25 can drive the coating roller 21 to approach and contact the plate.

[0042] For the second drive seat 13, the positioning cylinder 114 does not need to be moved. The coating roller 21 can be driven to move by the positioning module 25, thereby achieving the effect of driving the coating roller 21 to contact or leave the plate without moving the second drive seat 13.

[0043] Specifically, the scraper module 24 includes a scraper 26 and a scraper driving member 27 for driving the scraper 26 to move back and forth. The scraper 26 is used to resist the plate.
