[0050] 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, and 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.

[0051] The present invention provides a vertical coating device for plates, comprising a plate turning mechanism 1, a transfer mechanism 2, a vertical coating device 3 and an oven 4.

[0052] The flipping mechanism 1 is used to flip the plate 8 of the flat plate to an upright state;

[0053] The transfer mechanism 2 is used to transfer the plate 8 in an upright state to the vertical coating device 3;

[0054] The vertical coating device 3 includes a coating drive mechanism 31, a clamping mechanism 34 and two coating mechanisms 32. There is a gap 33 between the two coating mechanisms 32. The coating drive mechanism 31 is used to drive the two coating mechanisms 32 to move closer to or farther from each other. The clamping mechanism 34 is located below the gap 33. The clamping mechanism 34 is used to clamp the vertically placed plate 8 and drive the plate 8 to move along the axial direction of the coating mechanism 32 to adjust the relative position of the plate 8 and the coating mechanism 32.

[0055] The transfer mechanism 2 is also used to transfer the vertically coated plate 8 to the oven 4;

[0056] The oven 4 is used to dry the coated plate 8 .

[0057] The execution actions of the present invention are specifically as follows:

[0058] A. conveying plate 8 for loading;

[0059] B. Flip the plate 8 from the flat state to the upright state;

[0060] C. Pick up the erected plate 8 and lift it, and then transfer it to the vertical coating device 3;

[0061] D. Insert the plate 8 from top to bottom into the vertical coating device 3. After being clamped and adjusted by the vertical coating device 3, the plate 8 is vertically coated by the vertical coating device 3. The vertical coating device 3 drives the plate 8 to rise during the vertical coating process;

[0062] E. Pick up the board 8 and transfer it to be baked.

[0063] The present invention inserts the plate 8 into the coating device from top to bottom, first clamps the plate 8 through the coating device to adjust the position of the plate 8, and then coats the plate 8 through the coating device, thereby ensuring that the roller of the coating device is in contact with a specific position of the plate 8, that is, the effect of coating a specific area of ​​the plate 8 is achieved, so that the plate 8 has a blank area after coating, which is convenient for clamping and transferring.

[0064] Furthermore, the flipping mechanism 1 includes a clamping plate module 16, a transmission module 11, a flipping drive module 311, a flipping module 13 and a fixed plate module 14. The transmission module 11 is used to transmit the plate 8. The fixed plate module 14 is used to position the plate 8 in place on the transmission module 11. The flipping drive module 311 is connected to the transmission module 11 through the flipping module 13 to drive the transmission module 11 to flip, so as to drive the plate 8 to flip to an upright state. The clamping plate module 16 is used to clamp the upright plate 8 and lift it.

[0065] In actual use, the transmission module 11 and the flip module 13 are both installed on the frame 17, and the fixed plate module 14 is installed on the transmission module 11; the transmission module 11 is a structure for transmission by transmission wheels or transmission rollers, that is, there is a gap 33 between two adjacent transmission wheels / rollers. This structure is a conventional means and will not be repeated here.

[0066] During operation, the plate 8 is moved by the transmission module 11. When the plate 8 placed flat on the transmission module 11 is transmitted to the end of the transmission module 11, it is in place. At this time, the fixed plate module 14 positions the plate 8. Then the flip drive module 311 drives the transmission module 11 to flip through the flip module 13 to drive the plate 8 to flip 90°. Then the external clamping plate module 16 clamps the plate 8 from the top of the plate 8 and drives the plate 8 to move to the next station. Compared with the prior art, the present invention is simple in action and ensures that the plate 8 is clamped at the top and transferred to the coating after stable flipping, so that the entire process is simplified.

[0067] In this embodiment, the flip module 13 includes a flip shaft 131 and two flip members 132. The two flip members 132 are respectively provided with two ends of the flip shaft 131. One end of the flip member 132 is connected to the transmission module 11, and the flip driving module 311 drives the other end of the flip member 132.

[0068] In actual use, the flip driving module 311 includes two flip cylinders, which are arranged one by one with the two flip members 132; the flip shaft 131 is connected to non-end positions of the flip member 132, and the other end of the flip member 132 is arranged on the piston rod of the flip cylinder.

[0069] In this embodiment, the flip cylinder is not shown in the accompanying drawings, but the driving shaft 133 is shown in the accompanying drawings. The flip cylinder can be located above or below the flip member 132, and the piston rod of the flip cylinder is connected to the flip shaft 131. The piston rod of the flip cylinder is extended and retracted to drive the flip member 132 to flip around the flip shaft 131, thereby utilizing the lever principle to achieve the effect of driving the entire transmission module 11 to flip.

[0070] In this embodiment, the fixed plate module 14 includes at least one fixed plate assembly 141, and the fixed plate assembly 141 includes a fixed plate cylinder 144, a supporting plate member 145 and a pressure plate member 146. The supporting plate member 145 is used to support the plate 8 in place on the transmission module 11, and the fixed plate cylinder 144 is used to drive the pressure plate member 146 to move closer to or away from the supporting plate member 145. The pressure plate member 146 cooperates with the supporting plate member 145 to clamp the plate 8, thereby achieving the effect of clamping one end of the plate 8, ensuring that the plate 8 always conflicts with the transmission module 11 during the flipping process and will not detach from the transmission module 11.

[0071] Specifically, the fixed plate module 14 also includes a lifting module 142 and a fixed plate frame 143. There are two fixed plate components 141. Both fixed plate components 141 are installed on the fixed plate frame 143. The lifting module 142 is used to drive the fixed plate frame 143 to rise and fall relative to the transmission module 11.

[0072] The lifting module 142 preferably uses a cylinder as a power source, and the height of the fixed plate frame 143 is adjusted by the lifting module 142, so that after the plate 8 is in place, the supporting plate part 145 rises and first contacts the bottom of the plate 8, and then the fixed plate cylinder 144 drives the pressing plate part 146 to descend to clamp the plate 8, thereby ensuring the stability of the clamping of the plate 8.

[0073] Specifically, the fixed plate cylinder 144 is a rotary clamping cylinder, that is, when the pressure plate component 146 is clamped, it needs to be rotated to the top of the support plate component 145 before being lowered, and when the plate component 8 is released, it first rises and then rotates 90°, to ensure that the pressure plate component 146 will no longer contact the plate component 8 after the plate component 8 is released, so as to achieve the effect of giving way.

[0074] In this embodiment, the present invention also includes a centering alignment module 15, which includes a centering drive component 151 and two centering pushers 152. The centering drive component 151 is used to drive the two centering pushers 152 to move simultaneously so that the two centering pushers 152 are close to or away from each other. The two centering pushers 152 are located directly above the transmission module 11 and are used to force the plate 8 on the transmission module 11 to be centered.

[0075] The centering alignment module 15 is arranged on the frame 17, and protrudes from the bottom of the transmission module 11 to the top of the transmission module 11. The centering drive assembly 151 includes a motor and a belt, and the motor is used to drive the belt to rotate, and the two centering pushers 152 are respectively installed at both ends of the belt, and move simultaneously under the drive of the belt rotation, so as to achieve the effect of pushing the plate 8 to the center, so as to ensure that the fixed plate module 14 reliably clamps the specific position of the plate 8 to ensure the stability of the plate 8.

[0076] Specifically, the centering alignment module 15 also includes a centering lifting assembly 153 and a guide wheel assembly 154. The transmission direction of the guide wheel assembly 154 is perpendicular to the transmission direction of the transmission module 11. The lifting assembly is used to drive the guide wheel assembly 154 to lift and lower the plate 8 on the transmission module 111.

[0077] The centering lifting component 153 preferably uses a motor or a cylinder as a power source, that is, by driving the guide wheel component 154 to rise so that the guide wheel component 154 supports the plate 8 and temporarily leaves the transmission module 11, and then the centering push component 152 pushes the plate 8 to move, so that the plate 8 is centered along the transmission direction of the guide wheel component 154, thereby reducing the friction force on the plate 8 during the centering process and avoiding excessive wear of the plate 8.

[0078] In actual use, the splint module 16 includes a splint lifting assembly 161, a splint seat 162, a splint telescopic assembly 163 and two splint assemblies 164. The two splint assemblies 164 are spaced apart from the splint seat 162. The splint assembly 164 is used to clamp the erected panel 8. The splint telescopic assembly 163 is used to drive the splint seat 162 to move back and forth along the transmission direction of the transmission module 11. The splint lifting assembly 161 is used to drive the splint seat 162 to rise and fall.

[0079] That is, after the panel 8 is flipped to be upright, the clamping plate telescopic component 163 first controls the movement of the clamping plate seat 162 so that the two clamping plate assemblies 164 are located directly above the panel 8, and the lifting component controls the clamping plate seat 162 to descend so that the clamping plate assemblies 164 are located at the top two ends of the panel 8. Then, after the clamping plate assemblies 164 clamp the panel 8, the fixed plate module 14 releases the panel 8, thereby achieving the clamping of the panel 8 and loading it to the next workstation.

[0080] In actual use, the lifting assembly is preferably a motor screw structure, the splint extension assembly 163 is preferably a cylinder, and the splint assembly 164 is preferably a pneumatic finger.

[0081] In this embodiment, the transfer mechanism 2 includes a rotating table 21 and a driving mechanism 22 for driving the rotating table 21 to rotate. The rotating table 21 is provided with a first clamping mechanism 23 and a second clamping mechanism 24. The first clamping mechanism 23 and the second clamping mechanism 24 are arranged crosswise with each other. The first clamping mechanism 23 and the second clamping mechanism 24 are both used to clamp the plate 8 in an upright state.

[0082] Specifically, the structures of the first clamping mechanism 23 and the second clamping mechanism 24 are basically the same, and the two are preferably coplanar and vertically arranged. When in use, the first clamping mechanism 23 clamps the plate 8 to be coated, and the second clamping mechanism 24 clamps the coated plate 8, and then the driving mechanism 22 drives the rotating table 21 to rotate 90°, and the first clamping mechanism 23 transfers the plate 8 to be coated to the coating equipment, and the second clamping mechanism 24 transfers the coated plate 8 to the next station (such as the oven 4), and the coated plate 8 is clamped by the manipulator of the next station, so that the effect of transferring two plates 8 at one time is achieved, which is simple and efficient.

[0083] In this embodiment, the first clamping mechanism 23 includes a translation module 231, a clamping frame 232 and two clamping modules 233 both arranged on the clamping frame 232. The translation module 231 is installed on the rotating table 21. The translation module 231 is used to drive the clamping frame 232 to move forward and backward. The two clamping modules 233 are used to clamp the same end of the plate 8.

[0084] In actual use, the translation module 231 is mainly composed of a cylinder and a guide rail, that is, the cylinder drives the clamping frame 232 to slide on the guide rail, thereby achieving the effect of controlling the forward and backward movement of the clamping member, so that when the plate 8 is clamped and exchanged with an external robot, interference can be avoided by moving the clamping module 233 forward and backward.

[0085] Specifically, the clamping module 233 includes a first clamping member 234, a second clamping member 235 and a clamping cylinder 236. The first clamping member 234 and the clamping cylinder 236 are both installed on the clamping frame 232, and the second clamping member 235 is installed on the piston rod of the clamping cylinder 236. The first clamping member 234 and the second clamping member 235 are respectively provided with clamping patterns 2311 at the ends facing each other.

[0086] During actual use, the clamping cylinder 236 is a rotating clamping cylinder, that is, before clamping the plate 8, the clamping cylinder 236 controls the second clamping member 235 to extend and rotate, thereby achieving the giving way of the plate 8; then the translation module 231 drives the clamping frame 232 to move forward, so that the first clamping member 234 contacts one end of the plate 8, and at this time, the second clamping member 235 rotates to achieve the giving way of the plate 8; then the clamping cylinder 236 drives the second clamping member 235 to reset, that is, the second clamping member 235 first rotates until it is facing the first clamping member 234 and then retreats, and the clamping effect of the plate 8 is achieved through the cooperation of the first clamping member 234 and the second clamping member 235, which allows the second clamping member 235 to give way and clamp the plate 8 without lifting.

[0087] Specifically, the clamping frame 232 includes a mounting seat 237, a lifting module 238 and a clamping seat 239. The mounting seat 237 is installed on the rotating table 21, and the lifting module 238 is installed on the clamping seat 239. The lifting module 238 is used to drive the clamping seat 239 to rise and fall. The two clamping modules 233 are spaced apart from each other on the clamping seat 239.

[0088] Specifically, the clamping module further includes a sensor 2310, which is used to sense the position of the plate 8. Specifically, the sensor 2310 can be a conventional infrared transceiver or a photoelectric switch, and has two sensing ends, which are respectively used to sense whether there is a plate 8 at the front end of the second clamping member 235 and to sense whether there is a plate 8 directly below the clamping module 233, so as to realize automatic control.

[0089] That is, the present invention can realize position adjustment by driving the clamping seat 239 to rise and fall relative to the mounting seat 237 through the lifting module 238 according to the specifications of the plate 8 and the posture of the external equipment, so as to make the present invention more flexible.

[0090] In this embodiment, the first clamping mechanism 23 and the second clamping mechanism 24 are perpendicular to each other, and a counterweight 25 is provided at one end of the rotating platform 21 facing away from the first clamping mechanism 23 and the other end of the rotating platform 21 facing away from the second clamping mechanism 24. The counterweight 25 is provided to balance the forces at the four ends of the rotating platform 21, thereby ensuring that the first clamping mechanism 23 and the second clamping mechanism 24 will not shake when the rotating platform 21 rotates, thereby ensuring the stability of the transfer of the plate 8.

[0091] Of course, the above method is based on the first clamping mechanism 23 and the second clamping mechanism 24 being connected by wires, that is, the rotating table 21 has only two actions: forward rotation of 90° and reverse rotation of 90°, which is helpful to avoid the phenomenon of the wire being twisted.

[0092] like Fig.11As shown, as another implementation of this embodiment, the number of the first clamping mechanism 23 and the second clamping mechanism 24 are two respectively, and the two first clamping mechanisms 23 and the two second clamping mechanisms 24 are distributed on the rotating table 21 in a circular array with the rotating table 21 as the center. That is, in this embodiment, the rotating table 21 can achieve 360° rotation, making the movement more flexible; but in this way, it is necessary to use a conductive ring or other structure to realize the power connection of the first clamping mechanism 23 and the second clamping mechanism 24, which can prevent the intermediate wire from being twisted.

[0093] In this embodiment, the driving mechanism 22 includes a driving motor 221, a driving worm 222 and a driving gear 223. The driving motor 221 is used to control the rotation of the driving worm 222. The driving worm 222 is meshed with the driving gear 223. The driving gear 223 rotates coaxially with the rotating table 21. That is, the driving mechanism 22 uses the driving motor 221 as a power source to achieve the effect of driving the rotating table 21 to rotate stably and with high precision.

[0094] Specifically, the driving mechanism 22 further includes a limit switch 224 and a trigger 225. The number of the limit switches 224 is at least two, and at least two limit switches 224 are installed on the rotating table 21. The trigger 225 is used to be assembled to the outside, and the trigger 225 is used to rotate relative to the rotating table 21. The limit switch 224 is electrically connected to the driving motor 221. That is, the limit switch 224 is preferably a commonly used device such as a contact switch and a photoelectric switch. When the rotating table 211 rotates, the limit switch 224 rotates with the rotating table 21 until one of the limit switches 224 is triggered by the trigger 225, that is, the driving motor 221 stops, thereby ensuring the stability and accuracy of the angle of each rotation of the present invention.

[0095] In this embodiment, the coating mechanism 32 includes a coating roller 321, a coating rotating module 322, a coating seat 323 and a scraper module 324. The coating rotating module 322 is used to drive the coating roller 321 to rotate, the coating seat 323 is used to load the coating, the coating roller 321 is dipped in the coating seat 323 and coated on the plate 8, the coating roller 321 is used to contact the plate 8 for coating, and applies an upward driving force to the plate 8 during the coating process;

[0096] When the plate 8 rises to be separated from the coating roller 321 , the scraping module 324 is used to scrape off the excess coating at both ends of the bottom of the plate 8 .

[0097] When the present invention is working, the feeding mechanism lowers the vertically placed plate 8 to pass through the gap 33, and then the clamping mechanism 34 clamps it. Subsequently, the clamping mechanism 34 moves according to the relative position of the plate 8 and the coating mechanism 32 to adjust the position of the plate 8; the coating drive mechanism 31 controls the two coating mechanisms 32 to approach each other so that the two coating mechanisms 32 clamp the plate 8, and the coating mechanism 32 rotates to coat the plate 8 while driving the plate 8 to move upward; when the plate 8 is clamped by the coating mechanism 32, the clamping mechanism 34 releases the plate 8 to ensure that the plate 8 will not be pulled, thereby ensuring the safety of the plate 8.

[0098] The present invention realizes the position adjustment of the plate 8 before coating by setting the clamping mechanism 34, so that the plate 8 and the coating mechanism 32 can be reliably aligned, so that the length of the coating mechanism 32 can be reduced and reliable coating can still be performed. At the same time, when it is necessary to leave blank space on both sides of the plate 8, it can also be achieved through alignment.

[0099] In this embodiment, the clamping mechanism 34 includes two coating clamping plate modules 341, and the coating clamping plate module 341 includes a clamping plate driving member 342, a clamping plate transverse movement assembly 343 and two coating clamping plate assemblies 344. The clamping plate transverse movement assembly 343 is used to drive the clamping plate driving member 342 to move axially along the first coating mechanism 32. The two coating clamping plate assemblies 344 are both installed on the clamping plate driving member 342. The clamping plate driving member 342 is used to drive the two clamping plates to move closer to or away from each other. The two coating clamping plate assemblies 344 are used together to clamp the plate 8.

[0100] That is, when clamping, one of the coating clamping modules 341 needs to clamp, and then the coating clamping module 341 moves so that the other end of the plate 8 extends into the other coating clamping module 341, and is clamped by the other coating clamping module 341, thereby ensuring that the position of the plate 8 clamped by the coating clamping module 341 is not too deep.

[0101] Specifically, the clamping mechanism 34 further includes a plate recognition device (not shown in the figure), which is used to recognize the position of the plate 8 that the coating clamping module 341 is going to clamp / has clamped. The plate recognition device can be a conventional device such as a photoelectric switch, an infrared switch, etc., which can be set at a corresponding position below the coating mechanism 32, and the number is preferably more than two. That is, after the bottom of the plate 8 passes through the gap 33, a plate recognition device can recognize the plate 8, so a coating clamping module 341 will clamp the plate 8; then the coating clamping module 341 drives the plate 8 to move horizontally, and after another plate recognition device recognizes the plate 8, the coating clamping module 341 stops moving, and another coating clamping module 341 clamps the other end of the plate 8, thereby achieving the effect of clamping the corresponding depth; then the two coating clamping modules 341 move horizontally in the same direction / speed until another plate recognition device recognizes the plate 8, that is, the plate 8 has reached the position, and coating can be achieved.

[0102] In this embodiment, the coating drive mechanism 31 includes a driving module 311, a first driving seat 312, a second driving seat 313, a first limiting member 314 and a second limiting member 315. The two coating mechanisms 32 are respectively installed on the first driving seat 312 and the second zone action. The driving module 311 is used to drive the first driving seat 312 and the second driving seat 313 to move closer to or away from each other; the first limiting member 314 and the second limiting member 315 are respectively installed on the first driving seat 312 and the second zone action. When the first limiting member 314 conflicts with the second limiting member 315, the first driving seat 312 and the second driving seat 313 are no longer close to each other.

[0103] The first limit member 314 and the second limit member 315, preferably one of which is a commonly used device such as a photoelectric switch or a proximity switch. The setting of the first limit member 314 and the second limit member 315 ensures that the first drive seat 312 and the second drive seat 313 stop moving each time they approach each other by a certain distance, thereby ensuring that the gap 33 between the two coating mechanisms 32 reaches the expected value to avoid pinching the plate 8.

[0104] Specifically, the driving module 311 includes a coating driving motor 3111, a driving screw 3112 and a driving nut 3113. The driving nut 3113 is arranged on the first driving seat 312. The coating driving motor 3111 drives and connects the driving screw 3112, and the driving screw 3112 is screwed with the driving nut 3113. Through the cooperation between the coating driving motor 3111 and the screw nut structure, the first driving seat 312 is driven with high precision and stability, ensuring that the first driving seat 312 will not move excessively and cause a safety accident; in addition, when the first driving seat 312 moves, the second driving seat 313 does not move relative to the plate 8, ensuring safety.

[0105] Specifically, the driving module 311 also includes a positioning cylinder 3114, a positioning transmission member 3115 and a positioning limit member 3116. The positioning transmission member 3115 is installed on the second driving seat 313. The positioning transmission member 3115 is installed on the piston rod of the positioning cylinder 3114. The positioning limit member 3116 is used to interfere with the positioning transmission member 3115 to limit the moving stroke of the positioning transmission member 3115.

[0106] The arrangement of the position adjustment cylinder 3114, the position adjustment transmission member 3115 and the position adjustment limit member 3116 mainly plays the following roles:

[0107] 1. Adjust the position of the position-adjusting and limiting member 3116 to achieve the effect of adjusting the position of the second driving seat 313 , thereby achieving the function of adaptively adjusting according to the thickness of the plate 8 .

[0108] 2. Before the plate 8 descends, the first drive seat 312 is driven backward by the coating drive motor 3111, and the second drive seat 313 is driven backward by the positioning cylinder 3114, so as to make enough room for the plate 8 to descend; after the plate 8 is clamped and adjusted by the clamping mechanism 34, the positioning cylinder 3114 first drives the second drive seat 313 forward until the positioning transmission member 3115 contacts the positioning limit member 3116 so that the coating mechanism 32 of the second drive seat 313 contacts the plate 8, and then the coating drive motor 3111 drives the first drive seat 312 to approach the second drive seat 313, thereby making way for the loading plate 8 and avoiding excessive clamping and wear of the plate 8.

[0109] In this embodiment, the coating mechanism 32 includes a coating roller 321, a coating rotating module 322, a coating seat 323 and a scraper module 324. The coating rotating module 322 is used to drive the coating roller 321 to rotate, the coating seat 323 is used to load the coating, the coating roller 321 is dipped in the coating seat 323 and coated on the plate 8, the coating roller 321 is used to contact the plate 8 for coating, and applies an upward driving force to the plate 8 during the coating process;

[0110] When the plate 8 rises to be separated from the coating roller 321 , the scraping module 324 is used to scrape off the excess coating at both ends of the bottom of the plate 8 .

[0111] That is, during coating, the two coating rollers 321 rotate in opposite directions, so that the coating applied by the coating rollers 321 is applied to the plate 8 while driving the plate 8 to rise; after the plate 8 rises to a certain position, the external manipulator grabs the plate 8 and drives the plate 8 to continue to rise until the plate 8 leaves the coating rollers 321. However, during the time when the plate 8 rises, part of the coating slides down along the plate 8 under the action of gravity and accumulates at the bottom of the plate 8. At this time, the scraping mechanism scrapes off the excess coating and allows the coating to fall back on the coating rollers 321 / coating seat 323, achieving the effect of evenly coating the coating at various positions of the plate 8.

[0112] Specifically, the coating mechanism 32 further includes a positioning module 325 , and the positioning module 325 is used to drive the coating roller 321 to move back and forth on the coating driving mechanism 31 .

[0113] For the coating mechanism 32 of the first driving seat 312, the positioning module 325 can drive the coating roller 321 to move slightly, so that after the first driving seat 312 and the second driving seat 313 no longer move relative to each other, the positioning module 325 can drive the coating roller 321 to approach and contact the plate 8.

[0114] For the second driving seat 313, the positioning cylinder 3114 does not need to be moved. The coating roller 321 can be driven to move by the positioning module 325, so that the coating roller 321 can be driven to contact or leave the plate 8 without moving the second driving seat 313.

[0115] Specifically, the scraper module 324 includes a scraper 326 and a scraper driving member 327 for driving the scraper 326 to move back and forth. The scraper 326 is used to resist the plate 8.

[0116] Specifically, the vertical coating device 3 further includes a plate lifting module 35, which is used to pick up the top of the erected plate 8, so as to deliver the plate 8 between the two coating mechanisms 32, and take the plate 8 after vertical coating out from between the two coating mechanisms 32. It can be composed of a conventional lifting linear module equipped with a clamping claw, which will not be described in detail here.

[0117] It should be noted that step B specifically includes:

[0124] C3. The second clamping module 233 clamps the end of the plate 8, and then the first clamping module 233 releases the plate 8;

[0125] C4. The second clamping module 233 drives the plate 8 to rotate horizontally so that the plate 8 moves to the top of the vertical coating device 3;

[0126] The first clamping module 233 and the second clamping module 233 clamp the ends of the plate 8 at different positions and do not interfere with each other.

[0127] Step D specifically includes:

[0128] D1. Driving the two coating mechanisms 32 to move in a first direction relative to each other;

[0129] D2. driving the plate 8 downward so that the plate 8 passes through the gap 33 between the two coating mechanisms 32 and is in place, and then the plate 8 is clamped by the positioning mechanism;

[0130] D3. The positioning mechanism drives the plate 8 to move along the second direction to adjust the relative position of the coating mechanism 32 and the plate 8;

[0131] D4. Control the two coating mechanisms 32 to move closer to each other to clamp the plate 8, and then the positioning mechanism releases the plate 8;

[0132] D5. The two coating mechanisms 32 rotate in opposite directions so that the plate 8 is driven to rise during the coating process of the plate 8;

[0133] D6. Clamp the end of the plate 8 to remove the plate 8 from between the two coating mechanisms 32;

[0134] D7. The paint at the front end of the plate 8 is scraped off the plate 8 by the scraping module 324, and the paint falls onto the coating mechanism 32 for recovery.

[0135] Wherein, step D4 specifically includes:

[0136] D41. The adjustment module 325 moves to drive the coating mechanism 32 connected thereto, until the adjustment module 325 contacts the stopper and the adjustment module 325 stops moving. At this time, the coating mechanism 32 connected to the adjustment module 325 contacts one end surface of the plate 8;

[0137] D42. The drive module 311 drives the coating mechanism 32 connected thereto to approach the coating mechanism 32 connected to the positioning module 325 until the first stopper 314 and the second stopper 315 collide or trigger each other, and the drive module 311 stops moving. At this time, the coating mechanism 32 connected to the drive module 311 contacts the other end surface of the plate 8;

[0138] D43. The positioning mechanism releases the plate 8, and the two coating mechanisms 32 clamp the plate 8 so that the plate 8 remains suspended.

[0139] Step E specifically includes:

[0140] E1. The rising module of the plate 8 clamps the end of the plate 8 and drives the plate 8 to rise;

[0141] E2. After the plate 8 is lifted to a preset height, the second clamping module 233 clamps the end of the plate 8, and then the plate 8 lifting module releases the plate 8;

[0142] E3. The second clamping module 233 drives the plate 8 to rotate horizontally so that the plate 8 enters the entrance of the oven 4;

[0143] E4. The baking clamping module 41 in the oven 4 clamps the plate 8, and then the second clamping module 233 releases the plate 8;

[0144] E5. The baking clamping module 41 in the oven 4 clamps the plate 8 and drives the plate 8 to move in the oven 4, and the plate 8 is baked during the movement;

[0145] The positions of the ends of the plate 8 clamped by the plate 8 lifting module and the second clamping module 233 are different and do not interfere with each other.

[0146] In step E, the baking clamping module 41 is driven to move in the oven by the chain transmission module 42, wherein the chain transmission module 42 has an upper transmission end 43 and a lower transmission end 44, the lower transmission end 44 is used to transmit the baking clamping module 41 from the front end of the oven 4 to the rear end of the oven 4, and the upper transmission end 43 is used to transmit the baking clamping module 41 from the rear end of the oven 4 to the front end of the oven 4; step E4 specifically includes:

[0147] E41. In the process of moving the upper transmission end 43 of the baking clamping module 41 to the lower transmission end 44, the baking clamping module 41 is lowered relative to the plate 8 and clamps the end of the plate 8;

[0148] E42. The second baking clamping module 41 releases the plate 8;

[0149] E43. The baking clamping module 41 starts to move at the head end of the lower transmission end 44.

[0150] The baking clamping module 41 is an elastic clamp, that is, the chain transmission module 42 must be a closed loop shape, and the baking clamping module 41 moves from the upper transmission end 43 to the lower transmission end 44 at the head end of the chain transmission module 42. In step E4, the second baking clamping module 41 first moves the plate 8 to the head end position of the chain transmission module 42, and then when the chain transmission drives the baking clamping module 41 to move from the upper transmission end 43 to the lower transmission end 44, the plate 8 enters the clamping port of the baking clamping module 41 and opens it, and then the second clamping module 233 releases the plate 8, and the baking clamping module 41 can clamp the plate 8 under the action of elastic force and drive the plate 8 to move along the lower transmission end 44, achieving the effect of delivering the plate 8.

[0151] Of course, for the purpose of stable clamping, the baking clamping module 41 can be a clamp driven by a cylinder, and the clamping mechanism of the second clamping module 233 is powered by a rotating clamping cylinder. This can achieve the action that after the baking clamping module 41 clamps the plate 8, the clamping mechanism of the second clamping module 233 first extends out and then rotates. After the baking clamping module 41 drives the plate 8 to leave the clamping mechanism of the second clamping module 233, the clamping mechanism of the entire second clamping module 233 retreats under the action of the cylinder to achieve a giving way effect.

The secondary transfer mechanism is used to transfer the dried plate 8 to the secondary coating device 6, the secondary coating device 6 is used to perform secondary coating on the plate 8, and the secondary oven 7 is used to dry the plate 8 after the secondary coating.

[0153] The structure and principle of the secondary transfer mechanism, secondary coating device 6 and secondary oven 7 are generally the same as those of the transfer mechanism 2, vertical coating device 3 and oven 4. The specific differences mainly lie in the conventional adjustments based on coating time, baking time, etc., which will not be repeated here.
