Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen printing inspection technology, and in particular to a screen printing inspection device with its own light source. Background Technology
[0002] Screen printing is a key tool in the printing process. It is widely used in screen printing and is mainly used to transfer patterns or text onto a substrate using ink. It transfers patterns to the surface of another object through grooves, convex surfaces, or cutout structures to achieve graphic reproduction.
[0003] Existing screen printing inspection devices require inspection of both the front and back of the screen during inspection. However, operators often cannot ensure that the screen is in the same position for both inspections after flipping it over. This can lead to issues such as pinholes being missed due to positional discrepancies, which can cause the screen to be partially obscured by shadows from the light source. This reduces the accuracy of the inspection and affects the printing quality. Utility Model Content
[0004] This utility model discloses a screen printing plate inspection device with its own light source, which aims to solve the technical problem that the existing inspection device has positional offset when performing two-sided inspection, resulting in light shadows and affecting the inspection accuracy and printing quality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A screen printing plate inspection device with a built-in light source includes an inspection table. A clamping and flipping module is provided on the top of the inspection table. The clamping and flipping module includes a mounting platform and multiple adjusting seats. A mounting frame is bolted to one side of the mounting platform, and a ring light source is fixedly connected to the bottom of the mounting frame. A detector is provided on one side of the ring light source. A display screen is fixedly connected to one side of the mounting frame. Each of the multiple adjusting seats has a circular hole on one side, and a rotating shaft is movably connected inside each of the circular holes. A positioning plate is fixedly connected to the outer wall of the rotating shaft. Each of the multiple positioning plates is movably connected to one side of the adjusting seat, and a clamping component is fixedly connected to one side of the positioning plate. A buffer protection module, including a buffer air cushion, is provided on the side of each of the multiple positioning plates away from the clamping component.
[0007] In a preferred embodiment, the top of the testing platform is fixedly connected to two telescopic rods, one end of which is fixedly connected to one side of the same mounting platform. Two adjusting platforms are movably connected to one side of the mounting platform. An electric drive rod is fixedly connected to one side of each adjusting platform, and a mounting plate is fixedly connected to the drive end of the electric drive rod. A deflection plate is fixedly connected to the top of each of the two adjusting platforms, and limit holes are provided on one side of both the deflection plate and the mounting plate. A movable shaft is fixedly connected inside each of the two limit holes. Two horizontal plates are bolted to one side of each mounting platform, and the top of each horizontal plate... Two sliding grooves are provided, and two movable shafts are slidably connected inside the sliding grooves respectively; each of the multiple adjustment seats has a movable hole on one side, and the movable shaft is movably connected inside the movable hole; the bottom of the adjustment table is fixedly connected to a limit post, and the outer wall of one of the movable shafts on the same side as the limit post is fixedly connected to the same pull rope; each of the multiple positioning plates has an opening on one side, and a fixed cylinder is movably connected inside the multiple openings; the outer walls of two fixed cylinders on the same side are fixedly connected to the same flipping component; the top of the horizontal plate is fixedly connected to a servo motor, and the drive end of the servo motor is connected to one side of the flipping component through a coupling.
[0008] In a preferred embodiment, each of the multiple positioning plates is bolted to a support member on one side, and one end of the support member has a through hole, through which a telescopic rod II is fixedly connected. The driving end of the telescopic rod II is fixedly connected to one side of the buffer air cushion. Each of the multiple support members has a square groove on the side away from the positioning plate, and a connecting plate is slidably connected inside the square groove. One end of the connecting plate is fixedly connected to one side of the buffer air cushion.
[0009] As can be seen from the above, the screen printing detection device with a built-in light source provided by this utility model uses a clamping and flipping module to ensure that the screen printing position is consistent before and after flipping. This avoids problems such as pinholes and uneven mesh size on the back side caused by positional deviations that may result in the screen printing being covered by light shadows, thus reducing detection accuracy. At the same time, it can also avoid defects such as ink leakage and printing ghosting during use, which affect the technical effect of printing quality. Attached Figure Description

The side of each of the multiple positioning plates 215 away from the clamping member 216 is provided with a buffer protection module 3, and the buffer protection module 3 includes a buffer air cushion 304.
[0018] Reference Figure 1 , Figure 2 and Figure 3In a preferred embodiment, two telescopic rods 201 are fixedly connected to the top of the testing platform 1, and one end of each telescopic rod 201 is fixedly connected to one side of the same mounting platform 202. Two adjusting platforms 203 are movably connected to one side of the mounting platform 202. An electric drive rod 205 is fixedly connected to one side of each adjusting platform 203, and a mounting plate 211 is fixedly connected to the drive end of the electric drive rod 205. A deflection plate 204 is fixedly connected to the top of each adjusting platform 203, and a limit hole is provided on one side of both the deflection plate 204 and the mounting plate 211. A movable shaft 209 is fixedly connected inside each of the two limit holes. Two horizontal plates 208 are bolted to one side of each mounting platform 202, and the top of each horizontal plate 208... Each part has two sliding grooves, and two movable shafts 209 are slidably connected inside the sliding grooves; each of the multiple adjustment seats 212 has a movable hole on one side, and the movable shaft 209 is movably connected inside the movable hole; the bottom of the adjustment table 203 is fixedly connected to a limit post 206, and the outer wall of one movable shaft 209 on the same side as the limit post 206 is fixedly connected to the same pull rope 210; each of the multiple positioning plates 215 has an opening on one side, and a fixed cylinder 214 is movably connected inside the multiple openings; the outer walls of two fixed cylinders 214 on the same side are fixedly connected to the same flipping part 217; the top of the horizontal plate 208 is fixedly connected to a servo motor 207, and the drive end of the servo motor 207 is connected to one side of the flipping part 217 through a coupling.
[0019] Reference Figure 3 and Figure 4 In a preferred embodiment, a support member 301 is bolted to one side of each of the multiple positioning plates 215, and a through hole is provided at one end of the support member 301. A telescopic rod 302 is fixedly connected inside the through hole, and the driving end of the telescopic rod 302 is fixedly connected to one side of the buffer air cushion 304.

One end of the connecting plate 303 is fixedly connected to one side of the buffer air cushion 304.
[0020] Working principle: After single-sided testing is completed, the electric drive rod 205 is activated. The electric drive rod 205 drives the mounting plate 211 and the movable shaft 209 to reciprocate within the upper sliding groove of the horizontal plate 208. Since the length of the pull rope 210 remains constant, the pull rope 210 causes the adjusting table 203 to deflect, which in turn causes the deflection plate 204 to drive the adjusting seat 212 and the positioning plate 215 to deflect, causing the two clamping parts 216 to move relative to each other and clamp and fix the screen. The telescopic rod 201 is then activated. When the telescopic rod 201 moves the mounting table 202 upward to a suitable height, the servo motor 207 is activated. The servo motor 207 drives the flipping part 217 to perform a circular motion. The flipping of the screen allows for inspections requiring a specific angle, ensuring consistent placement of the screen in both inspections. This prevents issues like pinholes or uneven mesh size on the back side caused by shadows from lighting deviations, reducing inspection accuracy. It also avoids ink leakage and ghosting during printing, ensuring print quality. Simultaneously, the activation of telescopic rod 302 moves the connecting plate 303 and the buffer air cushion 304, providing cushioning protection for different areas of the screen and minimizing impact during flipping, thus preventing damage.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
