Description

Technical Field

[0001] The utility model relates to the technical field of screen plate production equipment, in particular to a high-precision tape pasting machine. Background Art

[0002] A screen plate is composed of a screen frame and a screen. When making a screen plate, different meshes of screens and appropriate-sized screen frames need to be selected according to different materials of printing substrates and precision requirements. Then, the screen frame is polished so that the screen can be tightly combined with the screen frame, and then processes such as stretching the screen and cutting are carried out to form a screen plate. Since the screen and the screen frame are fixed by bonding with glue or paint, the edge of the screen is prone to de-bonding during use, resulting in final damage. To solve this problem, a tape pasting process is added after the screen plate is made, that is, a tape is pasted on the edge where the screen contacts the screen frame to prevent the screen from de-bonding. The screen plate has a rectangular structure, and taping is required for all four sides.

[0003] When the existing tape pasting machine (such as a translational rolling tape pasting device disclosed in the application number 201721609268.0) is performing the tape pasting work, it can only position the starting point of the tape, and cannot position the starting point and the ending point of the tape simultaneously. Since the accuracy of the moving platform, the accuracy of parts, rigidity, and the deformation of the workpiece will all affect the tape pasting accuracy. If only the starting point of the tape is positioned, there will be a deviation between the ending point and the starting point of the tape. The accuracy of traditional tape pasting machines is generally about 0.5 - 1 mm, but the screen printing industry has relatively high accuracy requirements, generally within plus or minus 0.1 mm. Ordinary tape pasting machines are difficult to meet the accuracy requirements of the screen printing industry. Summary of the Utility Model

Detailed implementation manner

[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] The present utility model provides a high-precision pasting machine, and its structure is as Figure 1 - Figure 8As shown in the figure, it includes a rotating unit 100, a glue feeding unit 200, a glue pulling and pasting unit 300, and an identification unit 400. The rotating unit 100 includes a workbench 110, and a screen printing plate is horizontally placed on the workbench 110. The glue feeding unit 200 is arranged above the workbench 110 and can move along the X, Y, and Z directions to convey the tape. The glue pulling and pasting unit 300 is arranged above the workbench 110 and can move along the X, Y, and Z directions, and includes a glue pulling assembly 310 and a glue pasting assembly 320. The glue pulling assembly 310 is used to receive the leading end of the tape conveyed by the glue feeding unit 200 and can press or release the leading end of the tape. The glue pasting assembly 320 is used to press the tape downward so that the tape is pasted on the screen printing plate. The identification unit 400 is arranged above the tape and can move along the X and Y directions to identify the starting and ending positions of the tape and determine the deviation values of the starting and ending points.

[0032] In use, place the screen printing plate to be glued horizontally on the workbench 110, and make the edge of the screen printing plate to be glued parallel to the X direction. The tape can be conveyed through the tape feeding unit 200. By controlling the movement of the tape pulling and gluing unit 300 in the X, Y, and Z directions, the tape pulling and gluing unit 300 can be made to correspond to the tape feeding unit 200. Then, operate the tape pulling and gluing unit 300 to move along the X direction, so that the tape pulling and gluing unit 300 approaches the tape feeding unit 200. After the tape pulling and gluing unit 300 approaches the tape feeding unit 200, the tape pulling assembly 310 receives the leading end of the tape conveyed by the tape feeding unit 200 and presses the leading end of the tape. At this time, operate the tape pulling and gluing unit 300 to move along the X direction again, so that the tape pulling and gluing unit 300 moves away from the tape feeding unit 200, thereby pulling out the tape. Then, operate the tape feeding unit 200 and the tape pulling and gluing unit 300 to move along the Y direction until they reach directly above the edge of the screen printing plate to be glued. The identification unit 400 moves along the Y direction to directly above the tape and moves back and forth along the X direction to identify the starting point and the ending point positions of the tape and determine the deviation value between the starting point and the ending point. The tape feeding unit 200 and the tape pulling and gluing unit 300 slightly move in the Y direction according to the deviation value until the deviation value between the starting point and the ending point is within the preset range. At this time, the gluing assembly 320 is used to press the tape downward so that the tape is pasted on the screen printing plate to form a fixed point. Then, the tape pulling assembly 310 releases the leading end of the tape, and the tape pulling and gluing unit 300 moves along the Y direction, first gradually approaching the leading end of the tape and then gradually approaching the trailing end of the tape. During the process of the tape pulling and gluing unit 300 approaching the leading end of the tape, the tape from the fixed point to the leading end is pressed by the gluing assembly 320 and pasted on the screen printing plate. During the process of the tape pulling and gluing unit 300 approaching the trailing end of the tape, the tape from the fixed point to the trailing end is pressed by the gluing assembly 320 and pasted on the screen printing plate, realizing the gluing of the screen printing plate. Before gluing the screen printing plate, the starting point and the ending point of the tape can be positioned simultaneously through the tape feeding unit 200 and the tape pulling and gluing unit 300, and the starting point and the ending point of the tape can be adjusted so that the deviation value between the starting point and the ending point is within the preset range, having a high gluing accuracy and meeting the requirements of the screen printing industry for high-precision gluing.

[0053] To better understand the present invention, the working principle of the technical solution of the present invention will be described in detail below in conjunction with Figure 1 - Figure 9 :

[0054] During use, place the screen printing plate to be glued within the clamping area, and make two adjacent side walls of the screen printing plate abut against the corresponding first positioning post 131 and the second positioning post 132 respectively. By controlling the first clamping telescopic driving member 135 and the second clamping telescopic driving member 136, the first clamping telescopic driving member 135 can drive each of the first clamping blocks 133 to approach each of the first positioning posts 131, and clamp two opposite side walls of the screen printing plate via each of the first clamping blocks 133 and each of the first positioning posts 131. The second clamping telescopic driving member 136 can drive each of the second clamping blocks 134 to approach each of the second positioning posts 132, and clamp the other two opposite side walls of the screen printing plate via each of the second clamping blocks 134 and each of the second positioning posts 132, thereby realizing the fixation of the screen printing plate. At this time, one of the sides of the screen printing plate to be glued is parallel to the X direction. The tape on the tape roll bypasses each of the guiding rollers 250, then passes through the first conveying channel. By controlling the pressing telescopic driving member 264, the pressing telescopic driving member 264 is driven to move the pressing plate 262 upward, so that the pressing plate 262 approaches the sliding plate 261, and the tape is clamped via the pressing plate 262 and the sliding plate 261. Then, by controlling the tape feeding telescopic driving member 265, the tape feeding telescopic driving member 265 is driven to move the sliding plate 261 along the length direction of the tape feeding swing arm 220, thereby driving the tape to move forward, so that the leading end of the tape reaches directly below the tape feeding roller 263. By controlling the tape pulling and gluing unit 300 to move in the X, Y, and Z directions, the tape pulling and gluing unit 300 can be made to correspond to the tape feeding unit 200. Then, operate the tape pulling and gluing unit 300 to move in the X direction, so that the tape pulling and gluing unit 300 approaches the tape feeding unit 200. After the tape pulling and gluing unit 300 approaches the tape feeding unit 200, the tape pulling roller 311 is located directly below the tape feeding roller 263. At this time, the tape is located between the tape feeding roller 263 and the tape pulling roller 311. By controlling the roller rotation driving member 313, the output end of the roller rotation driving member 313 is driven to rotate, and the tape pulling roller 311 is driven to rotate via the transmission member 312, thereby pulling the leading end of the tape into the second conveying channel. By controlling the tape pressing telescopic driving member 315, the tape pressing telescopic driving member 315 can drive the tape pressing block 314 to approach the tape pulling roller 311, and clamp the tape via the tape pressing block 314 and the tape pulling roller 311. At this time, the entire tape pulling and gluing unit 300 moves away from the tape feeding unit 200 in the X direction, thereby pulling the tape apart. Then, operate the tape feeding unit 200 and the tape pulling and gluing unit 300 to move in the Y direction until they reach directly above the side of the screen printing plate to be glued. The camera 420 moves in the Y direction to directly above the tape and moves back and forth in the X direction.Identify the starting and ending positions of the tape, and determine the deviation values of the starting and ending points. The tape feeding unit 200 and the tape pulling and pasting unit 300 slightly move in the Y direction according to the deviation values until the deviation values of the starting and ending points are within a preset range. At this time, by controlling the swing arm rotation drive 323, the swing arm rotation drive 323 can drive the pasting swing arm 321 to reverse, so that the pasting roller 322 is located below the tape pulling roller 311. Since when the pasting roller 322 is located below the tape pulling roller 311, the pasting roller 322 is located between the tape feeding roller 263 and the tape pulling roller 311, continue to control the swing arm rotation drive 323, and the swing arm rotation drive 323 can continue to drive the pasting swing arm 321 to reverse, so that the pasting roller 322 presses the tape downward until the tape is pasted on the screen plate and forms a fixed point. Then, by controlling the pressing glue telescopic drive 315, the pressing glue telescopic drive 315 can drive the pressing glue block 314 away from the tape pulling roller 311, and release the leading end of the tape via the pressing glue block 314 and the tape pulling roller 311. The tape pulling and pasting unit 300 moves along the Y direction, first gradually approaches the leading end of the tape, and then gradually approaches the trailing end of the tape. During the process that the tape pulling and pasting unit 300 approaches the leading end of the tape, the tape from the fixed point to the leading end is pressed by the pasting roller 322 and pasted on the screen plate. During the process that the tape pulling and pasting unit 300 approaches the trailing end of the tape, the tape from the fixed point to the trailing end is pressed by the pasting roller 322 and pasted on the screen plate, realizing the pasting of the screen plate. Before pasting the screen plate, the starting and ending points of the tape can be positioned simultaneously by the tape feeding unit 200 and the tape pulling and pasting unit 300, and the starting and ending points of the tape can be adjusted so that the deviation values of the starting and ending points are within a preset range, having a high pasting accuracy and meeting the requirements of the screen printing industry for high-precision pasting.,

[0055] A high-precision pasting machine provided by the present utility model has the following beneficial effects:

[0056] (1) The clamping assembly 130 is used to clamp the screen plate to prevent the screen plate from moving during the process of pasting the screen plate, and further improve the pasting accuracy of the screen plate;

[0057] (2) The turntable rotation drive 120 is used to drive the workbench 110 to rotate, so as to paste other sides of the screen plate, avoiding manual adjustment of the position of the screen plate;

[0058] Before applying glue to the stencil, the starting point and the ending point of the tape can be positioned simultaneously by the glue feeding unit 200 and the tape pulling and gluing unit 300, and the starting point and the ending point of the tape can be adjusted so that the deviation value between the starting point and the ending point is within a preset range, with high glue application accuracy, meeting the requirements of the screen printing industry for high-precision glue application.
