Description

Technical Field

[0001] This application belongs to the field of screen printing technology, specifically relating to a screen printing plate spin-drying device. Background Technology

[0002] Screen printing is a printing process that uses a screen printing plate. The printing pattern is set on the screen printing plate. The printing pattern can pass through the ink, while the non-printing pattern cannot. Therefore, when printing using a screen printing plate, the ink passes through the pattern on the screen printing plate and is located on the substrate, thus printing the pattern on the screen printing plate onto the substrate.

[0003] In the production of screen printing plates, the screen is first fixed on the substrate, and impurities on the screen are cleaned using cleaning agents and degreasers. After cleaning and drying, photosensitive emulsion is applied to the screen, and then it is exposed. Finally, the exposed pattern is revealed by washing with water.

[0004] After the pattern on the screen is revealed by washing with water, the screen printing plate is taken out and the moisture on the screen printing plate is blown off with a high-pressure air gun. Finally, the screen printing plate is placed in an oven to dry. However, the high-pressure air gun drying method may blow off the fine lines on the screen printing plate, resulting in defective products. Utility Model Content

[0010] In one possible implementation, a limiting plate is connected to the L-shaped plate hinged to the limiting rod, and the limiting rod contacts the limiting plate after the limiting rod rotates away from the screen printing plate.

[0011] In one possible implementation, a protrusion is fixedly provided on the L-shaped plate hinged to the limiting rod, and a pivot on the limiting rod passes through the protrusion, with a limiting disc fixedly provided at the protruding end to limit the axial displacement of the limiting rod.

Detailed Implementation

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please refer to the following: Figures 1 to 11 The present application provides a screen printing plate spin-drying device. The screen printing plate spin-drying device includes a housing 1, a turntable 2, and a clamp 3. The housing 1 has a working space 11 inside and a loading / unloading port 12 on one side. The turntable 2 is rotatably disposed within the working space 11. The rotating shaft of the turntable 2 is horizontally arranged so that the working surface of the turntable 2 is vertically arranged. The clamp 3 is disposed on the working surface of the turntable 2. The clamp 3 includes L-shaped plates 31 that contact the four corners of the screen printing plate 4 to circumferentially limit the screen printing plate 4. The clamp 3 also includes a limiting structure 32 that axially limits the screen printing plate 4 to restrict the displacement between the screen printing plate 4 and the turntable 2.

[0021] This application provides a screen printing plate 4 spin-drying device. Compared with the prior art, after the exposed pattern is developed by washing with water, the screen printing plate 4 is placed on the L-shaped plate 31 on the turntable 2 so that the four corners of the screen printing plate 4 contact the four L-shaped plates 31, circumferentially limiting the screen printing plate 4; then, the screen printing plate 4 is axially limited by the limiting structure 32, which can fix the screen printing plate 4 on the turntable 2; the rotation of the turntable 2 can spin off the water on the screen printing plate 4, reducing the moisture on the screen printing plate 4. With the above-mentioned settings of this application, compared with the high-pressure air gun drying method, the spin-drying method of this application can reduce the impact on the pattern lines, thereby reducing the separation of the pattern lines from the screen.

[0022] A door panel 13 is hinged to the housing 1 at the access port 12. The other side of the door panel 13 is magnetically attached to the housing 1. Specifically, when the door is closed, the inner side of the door panel 13 contacts the opening side of the housing 1. A groove is provided at the position where the inner side of the door panel 13 contacts the opening side of the housing 1, and the magnet is fixed in the groove. The thickness of the magnet is the same as the thickness of the groove, so the magnet does not affect the closing of the door panel 13, allowing the inner side of the door panel 13 to contact the opening side of the housing 1. After the door panel 13 is magnetically attached to the housing 1, the door panel 13 closes the access port 12 of the housing 1. The door panel 13 has an observation window 14, and a handle 15 is also fixedly provided on the outer side of the door panel 13.

[0023] The housing 1 also includes a drive chamber 16, which is separated from the working space 11 by a partition 17. The rotating shaft of the turntable 2 passes through the partition 17. A drive motor is connected to the drive chamber 16, and the output shaft of the drive motor is connected to the input shaft of a reducer. The output shaft of the reducer is connected to the through end of the rotating shaft of the turntable 2. The rotating shaft of the turntable 2 is coaxially arranged with the turntable 2. A sleeve is fixedly installed on the partition 17 at the position of the drive chamber 16, and the sleeve rotates in conjunction with the rotating shaft of the turntable 2 to ensure the stability of the turntable 2's rotation. A support platform is fixedly installed inside the drive chamber 16, and the drive motor and reducer are fixed on the support platform. The output shaft of the reducer is connected to the rotating shaft of the turntable 2 via a flange.

[0024] Driven by the drive motor, the turntable 2 can rotate, which in turn drives the screen printing plate 4 to rotate, so as to spin dry the moisture on the screen printing plate 4. During the spin drying process, start at a low speed, for example, spin dry at a low speed of 300-500 rpm for 10-15 seconds, and then gradually increase the speed. The maximum speed should not exceed 800 rpm to reduce the possibility of pattern lines being spun off.

[0025] In some embodiments, such as Figures 1 to 11 As shown, the limiting structure 32 includes two limiting rods 321, which are vertically arranged. The positions of the limiting rods 321 correspond to the two L-shaped plates 31 arranged along the height direction, and the limiting rods 321 contact the outer side of the screen printing plate 4. Each limiting rod 321 has a T-shaped insert plate 322 fixedly provided at one end and a T-shaped insert plate 322 slidably provided at the other end. The end of the limiting rod 321 that slides with the T-shaped insert plate 322 has an external thread and is pressed against the T-shaped insert plate 322 by a nut 323. The L-shaped plate 31 has a T-shaped slot 311 that is inserted into the T-shaped insert plate 322. The limiting rods 321 do not contact the pattern area of ​​the screen printing plate 4, thus avoiding the problem of the lines in the pattern area falling off under the action of the limiting rods 321.

[0026] After placing the screen printing plate 4 on the four L-shaped plates 31, the four corners of the screen printing plate 4 can be limited to prevent circumferential displacement. By contacting the outer side of the screen printing plate 4 with the limiting rod 321 and cooperating with the T-shaped insert plate 322 and the T-shaped slot 311, the limiting rod 321 can be restricted to the two vertically placed L-shaped plates 31. By tightening the T-shaped insert plate 322 with the nut 323, the limiting rod 321 can be fixed to the two vertically placed L-shaped plates 31, which plays an axial limiting role for the screen printing plate 4.

[0027] It should be noted that the outer side of the screen printing plate 4 refers to the side of the screen printing plate 4 away from the turntable 2; the main frame of the screen printing plate 4 is a frame structure 41, and a base plate 42 is fixedly installed on one side of the frame structure 41, with through holes provided on the base plate 42; the screen is fixed to the outer side of the base plate 42 and covers the through holes, and the pattern on the screen is located in the middle area of ​​the through holes; when spin-drying, removing the water from the pattern area will not affect the quality of the subsequent pattern.

[0028] When installing the limiting rod 321, the T-shaped insert 322 fixedly installed on the limiting rod 321 can be inserted into the L-shaped plate 31 at the upper position, or the T-shaped insert 322 fixedly installed on the limiting rod 321 can be inserted into the L-shaped plate 31 at the lower position; the T-shaped insert 322 that slides with the limiting rod 321 can slide to the position of inserting into another L-shaped plate 31, and then the sliding T-shaped insert 322 is pressed against the limiting rod 321 by the thread engagement of the nut 323 with the limiting rod 321, so that the limiting rod 321 can be fixed on the two L-shaped plates 31.

[0029] In some embodiments, such as Figures 1 to 11 As shown, the limiting structure 32 includes two limiting rods 321; the two limiting rods 321 are vertically arranged; the limiting position corresponds to two L-shaped plates 31 arranged along the height direction, and the limiting rods 321 are in contact with the outer side of the screen printing plate 4; wherein, the bottom end of the limiting rod 321 is hinged to the lower L-shaped plate 31, and the hinge axis is parallel to the axis of the turntable 2; the top end of the limiting rod 321 is provided with an external thread, and a T-shaped insert plate 322 is slidably provided on the top end of the limiting rod 321, and the upper L-shaped plate 31 has a T-shaped slot 311 that is inserted and matched with the T-shaped insert plate 322; the top end of the limiting rod 321 is pressed against the T-shaped insert plate 322 by a nut 323.

[0030] The connection between the limiting rod 321 and the L-shaped plate 31 can be that one end is hinged and the other end is fixed to the two vertically arranged L-shaped plates 31 by a T-shaped insert plate 322 and a nut 323. The hinged end of the limiting rod 321 is located on the lower L-shaped plate 31. After the limiting rod 321 is rotated away from the screen printing plate 4, the limiting rod 321 can be stably kept in the rotated position under its own weight, which will not affect the picking and putting away of the screen printing plate 4.

[0031] After placing the screen printing plate 4 on the L-shaped plate 31 on the turntable 2, the limiting rod 321 is rotated to the vertical position. Then, the T-shaped insert plate 322 is inserted into the upper L-shaped plate 31, and the nut 323 is threaded into the limiting rod 321 to make the nut 323 press against the T-shaped insert plate 322. Through the above arrangement, the limiting rod 321 can be fixed on the two vertically arranged L-shaped plates 31 to axially limit the screen printing plate 4.

[0032] After spin-drying, there will be no water left on the screen printing plate 4 that can flow freely. Then, tighten the nut 323 to the end of the limiting rod 321, and slide the T-shaped insert 322 upward to separate it from the L-shaped plate 31. At this time, rotate the limiting rod 321 downward to separate it from the screen printing plate 4, making it easy to remove the screen printing plate 4 from the turntable 2. During the rotation of the limiting rod 321, after the T-shaped insert 322 slides to the end position of the limiting rod 321, the T-shaped insert 322 will not interfere with the L-shaped plate 31. The appropriate length of the limiting rod 321 can be selected according to the actual situation.

[0033] In some embodiments, such as Figures 1 to 11 As shown, the T-shaped insert 322 on the limiting rod 321 is replaced with a wedge plate, and the T-shaped slot 311 on the L-shaped plate 31 is replaced with a wedge groove.

[0034] The wedge plate and wedge groove can also play an axial limiting role. After being tightened by the nut 323, the limiting rod 321 can be fixed on the two vertically set L-shaped plates 31. During the spin-drying process, the limiting rod 321 will not separate from the L-shaped plates 31.

[0035] In some embodiments, such as Figures 1 to 11 As shown, a limiting plate 324 is connected to the L-shaped plate 31 that is hinged to the limiting rod 321. After the limiting rod 321 is rotated away from the screen printing plate 4, the limiting rod 321 comes into contact with the limiting plate 324.

[0036] The limiting plate 324 is fixed on the L-shaped plate 31. The top of the limiting plate 324 can be provided with an arc surface that contacts the limiting rod 321. By setting the limiting plate 324 on the L-shaped plate 31, the limiting rod 321 can be limited to the rotation position. At this time, the limiting rod 321 can press on the limiting plate 324 under its own weight and is in a stable state.

[0037] After the limiting rod 321 contacts the limiting plate 324, the limiting rod 321 separates from the screen printing plate 4, which will not affect the removal of the screen printing plate 4 from the turntable 2.

[0038] In some embodiments, such as Figures 1 to 11As shown, a protrusion 325 is fixedly provided on the L-shaped plate 31 that is hinged to the limiting rod 321. The rotating shaft on the limiting rod 321 passes through the protrusion 325, and a limiting disc 326 is fixedly provided at the protruding end to limit the axial displacement of the limiting rod 321.

[0039] The pivot on the limiting rod 321 is fixed on the limiting rod 321, and the protrusion 325 has a through hole for the pivot to pass through the limiting rod 321; the end of the pivot is fitted with a limiting plate 326, and the limiting plate 326 is fixed on the pivot by welding.

[0040] With the above settings, the limiting rod 321 can rotate around the pivot, and the limiting disc 326 can axially limit the limiting rod 321, reducing the possibility of the limiting rod 321 separating from the protrusion 325.

[0041] In some embodiments, such as Figures 1 to 11 As shown, a connecting plate 312 is fixedly provided on the outer side of the L-shaped plate 31, and the connecting plate 312 is provided with a connecting hole; the turntable 2 has a threaded hole aligned with the connecting hole; the connecting plate 312 and the turntable 2 are fixed by bolts.

[0042] The turntable 2 has several threaded holes, which can be selected according to the actual situation; the connecting plate 312 has at least two connecting holes to ensure that the connecting plate 312 is in a stable state after installation.

[0043] In some embodiments, such as Figures 1 to 11 As shown, a baffle 5 is fixedly provided at the bottom of the box 1 near the loading and unloading port 12. The baffle 5 and the side plate of the box 1 cooperate to form a water passage cavity 18. The side plate of the box 1 has a guide hole, which communicates with the water passage cavity 18. A water pipe 6 is connected to the outside of the box 1 at the position of the guide hole. The bottom wall of the water passage cavity 18 is a slope, and the guide hole is located at the lowest position of the slope.

[0044] During the spin-drying process, the water is spun onto the inner wall of the chamber 1; there is not much water on a single screen printing plate 4, so after spin-drying, no water will drip onto the screen printing plate 4; before placing the screen printing plate 4 on the turntable 2, the operator can wipe the top wall inside the chamber 1 to dry the water on the top wall of the chamber 1; or wipe the inside of the door panel 13.

[0045] The water that is spun onto the inner wall of the box 1 will adhere to the side wall of the box 1; after multiple screen printing plates 4 are spun dry, the water adhering to the inner wall of the box 1 will increase, eventually flowing downward into the water passage 18, and finally being guided out of the box 1 through the water pipe 6; after each screen printing plate 4 is spun dry, the operator wipes the top wall inside the box 1 to prevent water from accumulating on the top wall inside the box 1.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
