Description

Technical Field

[0001] The present application relates to the technical field of printing equipment cleaning, and in particular to a screen frame cleaning and drying system. Background Art

[0002] Screen printing technology refers to using a screen as a base and making a screen printing plate with images through a photosensitive platemaking method. When printing, pour ink on one end of the screen printing plate, use a scraper to apply a certain pressure to the ink part on the screen printing plate, and move it at a constant speed toward the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh of the image part by the scraper onto the substrate. Screen printing technology (Screen printing) is widely used in the manufacture of Ag or Al electrodes in silicon-based solar cells and printed circuit boards (PCBs), as well as the preparation of etching protection layers.

[0003] Screen printing usually includes ink with specific properties, a reusable and designed screen frame and a rubber plate. The screen frame is a porous grid, such as polymer material or stainless steel wire material, and is manufactured by photochemical or mechanical processing. By squeezing the ink, the ink passes through the screen frame and is deposited on the substrate surface, a large area of ​​patterned film can be obtained.

[0004] Since the screen frame is generally reused, the ink on the screen needs to be cleaned after use. At present, the cleaning of the screen frame is mainly done manually. The common manual cleaning method is to soak the screen frame in a washing tank and use liquid medicine to clean it, and then use a high-pressure water gun to rinse it. The screen frame is mostly transferred manually between different cleaning equipment. However, during the manual transfer process, workers are easily exposed to the cleaning liquid, and it is easy to spill the liquid contaminated on the screen frame to other places on the workbench. At the same time, long-term contact with liquid medicine can easily damage the workers' skin. Summary of the invention

[0005] In order to realize the automatic transfer of the screen frame between different cleaning equipments and reduce the workload of workers, the present application provides a screen frame cleaning and drying system.

[0011] By adopting the above technical solution, when the screen frame is transferred from the chemical washing tank to the rinsing table, the lifting component is first started to lift the screen frame from the chemical washing tank and transfer it to the transition slide. Then, under the action of the second horizontal driving component, the lifting component drives the screen frame from the transition slide to the rinsing table to be further rinsed with clean water.

[0012] When the screen frame moves along the side wall of the drug washing tank to the transition slide, part of the liquid medicine on the screen frame flows into the drug washing tank through the side wall of the drug washing tank during the transfer process, and the other part of the liquid medicine flows into the liquid accumulation tank on the transition slide. The liquid medicine is not easy to splash everywhere during this process, making the workbench cleaner and tidier. At the same time, the lifting component drives the screen frame to move, so the workers do not need to directly touch the screen frame with liquid medicine, which reduces the workload of the workers and is also beneficial to protecting the workers' skin.

[0013] Optionally, the first transfer mechanism further includes a first horizontal drive assembly, the first horizontal drive assembly includes a first drive member, a first conveyor belt and a movable support, the first drive member is arranged at one side of the drug washing tank, the first conveyor belt is wound around the outer side of the corresponding output shaft of the first drive member and extends along the length direction of the drug washing tank, and the movable support is arranged on the corresponding first conveyor belt;

[0014] The movable support is provided with a first clamping assembly, and the first clamping assembly extends from one side of the drug washing tank into the drug washing tank.

[0015] By adopting the above technical solution, the screen frame is moved from the feed side to the discharge side in the drug washing tank through the first horizontal driving component, so that the screen frame has sufficient contact time with the drug solution, thereby improving the drug washing efficiency; at the same time, the first clamping component is used to clamp the screen frame in this process, so that the screen frame is not easy to tip over during the movement.

[0016] Optionally, the first clamping assembly includes a second driving member, a first bidirectional screw rod and a first moving block capable of clamping the screen frame, the second driving member is arranged on the corresponding moving support, one end of the first bidirectional screw rod is connected to the output shaft of the second driving member, and the other end extends to the other side of the drug washing pool;

[0018] By adopting the above technical solution, the second driving member is started, the first bidirectional screw rotates and drives the first moving blocks at both ends to move along the direction of the first bidirectional screw, and the two first moving blocks approach each other and clamp the screen frame, or move away from each other to release the screen frame.

[0019] Optionally, the first transfer mechanism further includes a first cleaning assembly, the first cleaning assembly includes a third driving member, a second bidirectional screw, a second moving block and a first wiping member, the third driving member is arranged on the corresponding moving support, one end of the second bidirectional screw is connected to the output shaft of the third driving member, and the other end extends to the other side of the drug washing pool;

[0020] The number of the second moving blocks and the first wiping members is two groups, the two groups of the second moving blocks are sleeved on both ends of the second bidirectional screw rod, the second bidirectional screw rod is threadedly connected to the second moving blocks, each of the first wiping members is connected to the corresponding second moving block and is arranged in the vertical direction, and the two first wiping members can approach or move away from each other under the drive of the third driving member.

[0021] By adopting the above technical solution, the two second moving blocks move along the length direction of the second bidirectional screw rod while driving the first wiping member to move along the width direction of the screen frame. During the movement, the friction between the first wiping member and the screen frame is used to wipe off the ink on the screen frame, thereby accelerating the reaction speed between the ink and the liquid medicine.

[0023] By adopting the above technical solution, the fourth driving member can drive the lifting assembly to move along the direction of the movable slide rail. Since the movable slide rail is arranged along the length direction of the transition slide and the washing table, after the lifting assembly lifts the screen frame, it can further drive the screen frame to move into the washing table for the next washing work.

[0024] Optionally, a displacement mechanism is provided in the washing table, the displacement mechanism includes a transmission assembly and a limit assembly, the limit assembly includes a limit block for placing the screen frame, the transmission assembly is arranged at the bottom of the limit block and can drive the limit block to move along the width direction of the washing table.

[0025] By adopting the above technical solution, when the lifting assembly moves the screen frame into the limit block, the transmission assembly can drive the limit block to move along the width direction of the flushing station, thereby further driving the lower end of the screen frame to move. In this way, each corner of the screen frame can be flushed by the flushing liquid, thereby improving the flushing effect of the liquid medicine.

[0026] Optionally, the transmission assembly includes a displacement slide rail, a transmission belt, a driving wheel group and a driven wheel group, the displacement slide rail is arranged along the width direction of the washing station, the driving wheel group is fixed on the displacement slide rail, and the driven wheel group is slidably arranged on the displacement slide rail along the length direction of the displacement slide rail;

[0029] When the first driving wheel or the second driving wheel is rotated, the limiting block can move along the width direction of the washing station.

[0030] By adopting the above technical solution, when the first driving wheel or the second driving wheel is rotated, since the length of the transmission belt is constant and both ends of the transmission belt are fixed ends, when one of the driving wheels rotates in a corresponding direction, the transmission belt is driven to move, so that the position of the driven wheel group on the washing table changes, and the screen frame is driven to move accordingly. The moving direction of the driven wheel group is controlled by changing the rotation direction of the first driving wheel or the second driving wheel.

[0031] Optionally, one end of the displacement rail close to the first driving wheel extends to the outside of the washing station, and a rotating handle is provided at the upper end of the first driving wheel.

[0032] By adopting the above technical solution, the first driving wheel extends to the outside of the washing station, so the operator can rotate the first driving wheel outside the washing station to control the movement of the driven wheel group, and the rotating handle provides an operating space for the operator to operate conveniently.

[0033] Optionally, the displacement mechanism also includes a second cleaning component, which includes a second wiping member and a plurality of rinsing nozzles, wherein the plurality of rinsing nozzles are arranged at intervals on the upper end of the rinsing table along the length direction of the rinsing table, and both ends of the second wiping member are respectively connected to the upper end of the rinsing table, and the second wiping member is arranged along the length direction of the rinsing table.

[0036] By adopting the above technical solution, by rotating the fixing frame, different placement cavities correspond to the channels, and the flushed screen frame passes through the channels vertically into the placement cavity and is limited by the fixing assembly. A fixing frame can be installed with multiple screen frames, and after installation, the multiple screen frames are heated and dried by the heating pipe. In this process, since each screen frame is arranged vertically, it is conducive to the dripping of the flushing liquid under the action of gravity, thereby improving the drying efficiency.

[0037] In summary, the present application includes at least one of the following beneficial effects:

[0038] 1. By driving the screen frame to move through the lifting assembly, workers do not need to directly contact the screen frame with liquid medicine, which reduces the workload of workers and is also beneficial to protecting the workers' skin.

[0039] 2.

On the other hand, it is conducive to the full contact between the screen frame and the chemical liquid and the rinsing liquid, so that the rinsing liquid can be fully utilized when it is flushed downward, improving the efficiency of chemical washing and rinsing. In addition, when drying, it is kept in a vertical state, which is conducive to the liquid flowing down and improving the drying efficiency of the screen frame. BRIEF DESCRIPTION OF THE DRAWINGS
