[0027] Example 1

[0028] Please see Figure 1-9 An automatic solder resist ink coating device includes a support base 1, a feeding component 2, and a coating component 3. The feeding component 2 and the coating component 3 are both connected to the support base 1. The feeding component 2 includes a drive motor 207, a pushing part, and a conveying part. The pushing part is used to push a group of workpieces to the conveying part, and the conveying part then conveys the workpieces to the coating component 3 for coating processing. The drive motor 207 drives the feeding component 2 and the coating component 3 to work simultaneously.

[0029] The feeding assembly 2 includes a mounting vertical plate 201, a mounting frame 202, a mounting vertical rod 203, a mounting horizontal plate 204, a limiting plate 205, a motor plate 206, and a drive motor 207. The mounting vertical plate 201 is fixedly connected to both the front and rear sides of the support base 1. The mounting frame 202 is fixedly connected to the top surface of the mounting vertical plate 201. The mounting horizontal plate 204 is fixedly connected to the side of the mounting frame 202. The limiting plate 205 is fixedly connected to the four corners of the top surface of the mounting horizontal plate 204. The mounting vertical rod 203 is fixedly connected to the bottom surface of the mounting horizontal plate 204. The lower end of the mounting vertical rod 203 is fixedly connected to the support base 1. The motor plate 206 is fixedly connected to the side of one set of mounting frames 202. The drive motor 207 is fixedly connected to the motor plate 206.

[0030] The limiting plate 205 is used to restrict the position of the workpiece on the mounting plate 204 to ensure the accuracy of feeding. The drive motor 207 provides power to the entire feeding assembly 2 and coating assembly 3.

[0031] The material conveying section includes a material conveying crossbar 208, a material conveying roller 209, a lower support block 210, an upper support block 211, a connecting block 212, a telescopic rod 213, and an adapting spring 214. The lower support blocks 210 are fixedly connected to the bottom surface inside the mounting frame 202, and the connecting blocks 212 are fixedly connected to the lower support blocks 210. The telescopic rod 213 and the adapting spring 214 are fixedly connected to the top surface inside the mounting frame 202. The lower ends of the telescopic rod 213 and the adapting spring 214 are fixedly connected to the upper support block 211. The bottom surface of the support block 211 abuts against the connecting block 212. The upper support block 211 is slidably connected to the mounting frame 202. Material conveying crossbars 208 are rotatably connected between the upper support blocks 211 and between the lower support blocks 210. Material conveying rollers 209 are fixedly connected to each of the material conveying crossbars 208. One end of the lower material conveying crossbar 208 passes through the lower support block 210 and is fixedly connected to the output shaft of the drive motor 207. The highest point of the lower material conveying roller 209 is at the same horizontal position as the top surface of the mounting plate 204.

[0032] When the drive motor 207 starts, its output shaft drives the lower feed crossbar 208 connected to it to rotate. The rotation of the feed crossbar 208 causes the feed roller 209 to start rotating. During the rotation of the feed roller 209, friction is generated with the surface of the workpiece. The friction drives the workpiece to move along the surface of the feed roller 209 toward the coating assembly 3. The upper support block 211 is slidably connected to the mounting frame 202, so that the upper support block 211 can float up and down within a certain range to accommodate workpieces of different thicknesses. The highest point of the lower feed roller 209 is at the same horizontal position as the top surface of the mounting plate 204, ensuring that the workpiece can smoothly transition from the mounting plate 204 to the feed roller 209.

[0033] The feeding section includes a feeding wheel 215, a reduction wheel 216, a reduction crossbar 217, and an eccentric wheel 218. The other end of the lower feeding crossbar 208 passes through the lower support block 210 and is fixedly connected to the feeding wheel 215. The reduction crossbar 217 is rotatably connected between the mounting vertical plates 201. One end of the reduction crossbar 217 passes through the mounting vertical plate 201 and is fixedly connected to the reduction wheel 216. The reduction wheel 216 and the feeding wheel 215 are connected by a feeding belt 230. The eccentric wheel 218 is fixedly connected to the reduction crossbar 217.

[0034] The pushing section also includes a pushing groove 219, a pushing slide rail 220, a pushing slider 221, a connecting horizontal bar 222, a pushing vertical bar 223, a connecting vertical plate 224, a mounting block 225, a fixing plate 226, a pushing plate 227, an abutment wheel 228, and a pushing spring 229. The mounting horizontal plate 204 has a pushing groove 219. Two sets of symmetrically arranged pushing slide rails 220 and fixing plates 226 are fixedly connected to the bottom surface of the mounting horizontal plate 204 on the left and right sides of the pushing groove 219. The fixing plate 226 is located at the end of the pushing slide rail 220. Pushing sliders 221 are slidably connected within each pushing slide rail 220, and connecting blocks 221 are fixedly connected between them. A horizontal bar 222 and a pusher slider 221 are fixedly connected to a connecting vertical plate 224. A pusher vertical rod 223 is fixedly connected to the top surface of the connecting vertical plate 224. The upper end of the pusher vertical rod 223 passes through the pusher groove 219. An installation block 225 is fixedly connected to the top surface of the support base 1. A pusher plate 227 is rotatably connected to the installation block 225. The upper end of the pusher plate 227 is rotatably connected to the connecting horizontal bar 222. A pusher spring 229 is fixedly connected to the side of the fixing plate 226. The other end of the pusher spring 229 is fixedly connected to the pusher plate 227. An abutment wheel 228 is rotatably connected to the pusher plate 227. The outer edge of the abutment wheel 228 abuts against the outer edge of the eccentric wheel 218.

[0035] When the drive motor 207 starts, the feeding wheel 215 at the other end of the feeding crossbar 208 also rotates. The feeding wheel 215 drives the reduction wheel 216 on the reduction crossbar 217 to rotate through the transmission relationship. The reduction crossbar 217 then drives the eccentric wheel 218 to rotate. During the rotation of the eccentric wheel 218, its outer edge contacts the abutting wheel 228 on the push plate 227, pushing the push plate 227 to rotate around the mounting block 225. When the convex surfaces of the abutment wheel 228 and the eccentric wheel 218 contact each other, the pusher spring 229 is stretched, and the pusher rod 223 does not contact the workpiece. When the abutment wheel 228 contacts the concave surface of the eccentric wheel 218, the pusher spring 229 exerts a pulling force on the pusher plate 227. The pusher slider 221 drives the pusher rod 223 to move towards the conveyor roller 209 within the pusher groove 219, pushing a group of workpieces on the mounting plate 204 towards the conveyor roller 209, causing the workpieces to detach from the mounting plate 204 and fall onto the conveyor roller 209. When the eccentric wheel 218 rotates to its convex surface and abuts the abutment wheel 228 again, the pusher spring 229 is stretched again, and the pusher rod 223 returns to its original position.

[0036] Example 2

[0037] This embodiment adds the following improvements to Embodiment 1: The coating assembly 3 includes a coating box 301, a coating vertical plate 302, a coating rack 303, a first coating crossbar 304, a second coating crossbar 305, a coating roller 306, a guide roller 307, a first coating wheel 308, a second coating wheel 309, and a coating belt 310. The coating box 301 is fixedly connected to the support base 1. The coating box 301 is fixedly connected to the mounting frame 202 and the side of the mounting vertical plate 201. The coating vertical plates 302 are fixedly connected to the top front and rear sides of the coating box 301. The coating rack 303 is fixedly connected to the coating vertical plate 302. A first coating crossbar 304 is rotatably connected between the inner walls of the front and rear sides of the frame 303. Several sets of evenly distributed second coating crossbars 305 are rotatably connected between the coating vertical plates 302. A coating roller 306 is fixedly connected to the first coating crossbar 304. A guide roller 307 is fixedly connected to the second coating crossbar 305. One end of the first coating crossbar 304 passes through the coating frame 303 and is fixedly connected to a first coating wheel 308. A second coating wheel 309 is fixedly connected to the feeding crossbar 208, which is connected to the output shaft of the drive motor 207. The first coating wheel 308 and the second coating wheel 309 are connected by a coating belt 310.

[0038] The coating assembly 3 also includes an ink collection tank 311, an ink box 312, an ink pump 313, an ink drop head 314, and an ink guide tube 315. Several sets of evenly distributed ink drop heads 314 are fixedly connected to the top surface inside the coating rack 303. The ink drop heads 314 are located above the coating roller 306. An ink box 312 is fixedly connected to the support base 1. An ink pump 313 is fixedly connected to the ink box 312. The inlet of the ink pump 313 extends into the ink box 312. An ink guide tube 315 is fixedly connected to the outlet of the ink pump 313. The other end of the ink guide tube 315 is fixedly connected to the ink drop head 314. Several sets of evenly distributed ink collection tanks 311 are opened on the top surface of the coating box 301.

[0039] The workpiece located on the feed roller 209 is conveyed towards the coating assembly 3 by the rotating feed roller 209. The feed crossbar 208 transmits power to the first coating crossbar 304 through the transmission of the second coating roller 309, the coating belt 310, and the first coating roller 308, causing the coating roller 306 on the first coating crossbar 304 to rotate. At the same time, the ink pump 313 starts, conveying the ink in the ink tank 312 to the ink drop head 314 through the ink guide tube 315. The ink drop head 314 drips the ink onto the coating roller 306. When the workpiece is conveyed to the coating assembly 3, it passes through the rotating coating roller 306 under the guidance of the feed roller 307, and the coating roller 306 evenly coats the workpiece surface with ink. Excess ink drips into the ink collection tank 311 on the top surface of the coating tank 301 during the coating process and can be recycled and reused.

[0040] Working principle

[0041] When the drive motor 207 starts, its output shaft drives the lower feed crossbar 208 connected to it to rotate. The rotation of the feed crossbar 208 causes the feed roller 209 to start rotating. During the rotation of the feed roller 209, friction is generated with the surface of the workpiece. The friction drives the workpiece to move along the surface of the feed roller 209 toward the coating assembly 3. The upper support block 211 is slidably connected to the mounting frame 202, so that the upper support block 211 can float up and down within a certain range to accommodate workpieces of different thicknesses. The highest point of the lower feed roller 209 is at the same horizontal position as the top surface of the mounting plate 204, ensuring that the workpiece can smoothly transition from the mounting plate 204 to the feed roller 209.

[0042] When the drive motor 207 starts, the feeding wheel 215 at the other end of the feeding crossbar 208 also rotates. The feeding wheel 215 drives the reduction wheel 216 on the reduction crossbar 217 to rotate through the transmission relationship. The reduction crossbar 217 then drives the eccentric wheel 218 to rotate. During the rotation of the eccentric wheel 218, its outer edge contacts the abutting wheel 228 on the push plate 227, pushing the push plate 227 to rotate around the mounting block 225. When the convex surfaces of the abutment wheel 228 and the eccentric wheel 218 contact each other, the pusher spring 229 is stretched, and the pusher rod 223 does not contact the workpiece. When the abutment wheel 228 contacts the concave surface of the eccentric wheel 218, the pusher spring 229 exerts a pulling force on the pusher plate 227. The pusher slider 221 drives the pusher rod 223 to move towards the conveyor roller 209 within the pusher groove 219, pushing a group of workpieces on the mounting plate 204 towards the conveyor roller 209, causing the workpieces to detach from the mounting plate 204 and fall onto the conveyor roller 209. When the eccentric wheel 218 rotates to its convex surface and abuts the abutment wheel 228 again, the pusher spring 229 is stretched again, and the pusher rod 223 returns to its original position.

[0043] The workpiece located on the feed roller 209 is conveyed towards the coating assembly 3 by the rotating feed roller 209. The feed crossbar 208 transmits power to the first coating crossbar 304 through the transmission of the second coating roller 309, the coating belt 310, and the first coating roller 308, causing the coating roller 306 on the first coating crossbar 304 to rotate. At the same time, the ink pump 313 starts, conveying the ink in the ink tank 312 to the ink drop head 314 through the ink guide tube 315. The ink drop head 314 drips the ink onto the coating roller 306. When the workpiece is conveyed to the coating assembly 3, it passes through the rotating coating roller 306 under the guidance of the feed roller 307, and the coating roller 306 evenly coats the workpiece surface with ink. Excess ink drips into the ink collection tank 311 on the top surface of the coating tank 301 during the coating process and can be recycled and reused.
