Description

Technical Field

[0002] With the development of science and technology, smart electronic devices such as mobile phones and tablet computers can be seen everywhere in our lives. Most of these devices use touch screens as tools for collecting and identifying information.

[0003] As an important part of human-computer exchange, the touch screen can have different appearances, different sizes, and different application scenarios. There are multiple options to meet different applicable places. The appearance of the white cover plate is widely used in actual application scenarios, such as mobile phones, tablets, homes, and outdoors. Since the white cover plate needs to go through multiple processes during the processing, it requires the cooperation of multiple stations. At present, in the process of using the ink stacking system of the white cover plate, after the ink is printed on the surface of the substrate, in order to accelerate the curing and drying, it needs to be dried before normal discharge can be carried out. However, since it is easy for ink to splash on the processing table during spraying, and if the product cannot be taken away from the processing table during drying, the ink will be dried and solidified and piled on the surface of the processing table. This will not only affect the normal processing of subsequent products, but also increase the difficulty for managers to clean up the ink.

The fan 2 and the bellows 10, the bellows 10 are located directly above the processing table 3, and a plurality of air nozzles are installed on the bottom surface of the bellows 10. The air outlet of the hot air blower 2 is connected to the bellows 10 through a pipeline to transport hot air into the bellows 10. During processing, the substrate to be processed is placed on the inner side of the fixed frame 5, and then as the processing table 3 rotates, the substrate is first sent to the bottom of the printing mechanism, and then the spray gun 15 sprays the ink on the substrate according to the set program. After printing is completed, the processing table 3 rotates again, so that the printed substrate is sent to the bottom of the bellows 10 for drying.

[0044] The fixture includes two movable parts respectively mounted on two adjacent inner walls of the fixed frame 5 and two fixed clamping plates 19 respectively fixed on the other two inner walls of the fixed frame 5.

The fixed ring 6 cooperates with the movable sleeve 26 to drive the movable sleeve 26 to move toward the inside of the piston cylinder 7 when the movable sleeve 26 enters the inside of the fixed ring 6 from the notch. The setting of the ball 27 can prevent the movable sleeve 26 from directly contacting the inner ring of the fixed ring 6, thereby reducing the resistance of the movable sleeve 26 when it rotates with the processing table 3. The outer ring of the piston plate 1 and the outer ring of the piston plate 2 are both installed with sealing rings to avoid air leakage during movement.

[0045] The implementation principle of this embodiment is as follows: first, the telescopic member 11, the telescopic member 2 12, the telescopic member 3 and the servo motor are debugged by the PLC programmer, and then the substrate to be processed is placed inside one of the fixed frames 5, and then the servo motor is started to drive the rotating shaft 9 to rotate, so that the fixed frame 5 gradually turns to the bottom of the printing mechanism, and then another substrate can be placed in the next adjacent fixed frame 5. During the rotation of the processing table 3, the driving component for driving the clamp in the fixed frame 5 to tighten starts to work. When the movable sleeve 2 in the driving component is When the component 6 passes through the notch of the fixing ring 6 and enters the inner ring of the fixing ring 6, the movable sleeve 26 will move toward the inside of the piston cylinder 1 7 along the inclined surface component of the notch, thereby pressing the air in the piston cylinder 1 7 into the inside of the two piston cylinders 2 17, and then the piston plates in the two piston cylinders 2 17 move toward the net, which also makes the two movable clamping plates 18 gradually squeeze the substrate toward the two fixed clamping plates 19, until the movable sleeve 26 completely enters the inner ring of the fixing ring 6, the substrate is clamped between the two movable clamping plates 18 and the two fixed clamping plates 19, and the spring 2 is in a compressed state;

[0046] When the substrate moves to the bottom of the printing mechanism, the processing table 3 stops rotating intermittently, the printing mechanism is driven, and the telescopic member 2 14 is extended first, thereby lowering the height of the spray gun 15 and reducing the distance between the spray gun 15 and the substrate. Then the telescopic member 1 11 and the telescopic member 3 are extended and retracted according to the program setting, thereby driving the spray gun 15 to move along with the shape of the substrate, thereby spraying the ink on the surface of the substrate. After the printing is completed, the processing table 3 starts to rotate again under the drive of the servo motor, thereby gradually rotating the printed substrate to the bottom of the drying mechanism. At this time, the processing table 3 stops again, and then the hot air blower 2 is started to transport the hot air to the bellows 10. Finally, the hot air in the bellows 10 is sprayed from the nozzle and blown on the surface of the substrate, thereby drying the ink on the surface of the substrate. When the drying mechanism is drying the printed substrate, the printing mechanism simultaneously prints on the substrate in another fixed frame, thereby improving the production efficiency.

[0047] After drying, the processing table 3 continues to rotate, so that the movable sleeve 26 in the driving assembly moves out from the gap of the fixed ring 6, and then under the action of the spring 2, the movable sleeve 26 is bounced to the side away from the piston cylinder 7, so that the air in the two piston cylinders 17 can re-enter the interior of the piston cylinder 7, the clamp is loosened, and then the substrate clamped in the fixed frame 5 can be put down, achieving the purpose of automatic discharging.

[0048] Example 2

[0049] Combination Figure 1-5 and Figure 8 Based on Example 1, this embodiment is further improved in that:

[0050] A through hole is provided on one side of any placement slot 16 close to the center of the processing table 3. The solid material mechanism also includes a lifting assembly installed on the processing table 3 for driving the fixed frame 5 to lift and lower while the processing table 3 rotates. The lifting assembly includes a rack 22 movably installed in the through hole and a track 8 movably sleeved on the outside of the rotating shaft 9. The track 8 consists of an inclined part and a horizontal part. The top of the rack 22 extends to the top of the processing table 3 and is fixed with a fixed rod 21. One end of the fixed rod 21 is fixedly connected to the outer wall of the fixed frame 5. The track 8 is fixedly connected to the base. The bottom of the rack 22 extends to the processing table 3. Ball roller 2 is installed below and with the top surface of track 8. Ball roller 2 is installed to reduce the friction between the bottom of rack 22 and the top surface of track 8. Spring block 1 is sleeved on the outside of rack 22, and spring 1 is sleeved on the outside of rack 22. Spring 1 is located between the top of spring block 1 and the bottom surface of processing table 3. Rack 22 rolls on the top surface of track 8, so that rack 22 can rise and fall with the inclination of the top surface of track 8, and finally achieves the purpose of driving fixed frame 5 to rise and fall. Conveyor belt 4 is used to place substrate before the clamp clamps the substrate.

[0051] A scraper 23 for cleaning the ink on the surface of the conveyor belt 4 is installed in the placement groove 16. The scraper 23 is located below the conveyor belt 4, and the top of the scraper 23 abuts against the lower bottom surface of the conveyor belt 4. A discharge hole is provided on one side of the bottom surface of the placement groove 16, and the bottom surface of the placement groove 16 is inclined downward in the direction of the discharge hole. A clamp is installed on the inner wall of the fixed frame 5. A mounting groove 31 is provided on one side of the through hole. A connecting groove 33 is provided on the side of the mounting groove 31 close to the placement groove 16. A fixed shaft 29 is rotatably connected to the inner wall of one side of the mounting groove 31, and a transmission gear ring 30 is fixed to the other end of the fixed shaft 29. A plurality of ratchet teeth 35 are installed on the inner ring of the transmission gear ring 30. The outer ring of the transmission gear ring 30 extends into the through hole and meshes with the rack 22. A fixed shaft 23 is rotatably connected to the inner wall of the other side of the mounting groove 31. The other end of the fixed shaft 23 extends to the inner side of the transmission gear ring 30 and is fixed with a ratchet 28. The ratchet 28 is connected to the transmission gear ring 30. The gear ring 30 is coaxially arranged, and the ratchet 28 cooperates with the ratchet teeth 36 to drive the ratchet 28 to rotate when the rack 22 rises. Two transmission rollers 20 are rotatably connected in the placement groove 16, and the conveyor belt 4 is sleeved on the outside of the two transmission rollers 20. One end of the transmission roller 20 close to the through hole is fixed with a connecting shaft 34 coaxially arranged therewith, and the other end of the connecting shaft 34 extends into the connecting groove 33. A driven pulley is sleeved on the outside of the connecting shaft 34, and a driving pulley is sleeved on the outside of the fixed shaft 22. The driving pulley and the driven pulley are connected by a belt transmission. When the rack 22 rises, the transmission gear 30 is driven to rotate forward, and the ratchet teeth 35 rotate synchronously with the transmission gear ring 30 and simultaneously drive the ratchet 28 to rotate synchronously with it, so that the four conveyor belts rotate accordingly. Conversely, when the active rack 22 descends, the transmission gear ring 30 is driven to reverse, and at this time the ratchet teeth 38 do not drive the ratchet 28 to rotate.

[0052] The implementation principle of this embodiment is as follows: during the rotation of the processing table 3, when the bottom of the rack 22 is located at the horizontal section of the track 8, the fixed frame 5 is located on the top surface of the conveyor belt 4. When printing is completed and the fixed frame 5 gradually rotates to the bottom of the drying mechanism, the rack 22 begins to slide down the inclined surface of the track 8, so that the rack 22 gradually moves up, so that the fixed frame 5 leaves the surface of the conveyor belt 4, and at this time the clamp still clamps the printed substrate. At the same time, when the rack 22 moves up, it will drive the transmission gear 30 to rotate forward. After the transmission gear 30 rotates forward, it will drive the ratchet 28 to rotate through the ratchet teeth 35. After the ratchet 28 rotates, it will drive the connecting shaft 34 to rotate through the fixed shaft 2 32, and finally the transmission roller 20 rotates, so that the rack 22 that moves up At the same time, the conveyor belt 4 is driven to rotate. As the conveyor belt 4 rotates, the scraper 23 also scrapes the ink on the surface of the conveyor belt 4, so that when the fixed frame 5 rotates to the bottom of the bellows 10, the ink on the surface of the conveyor belt 4 has been scraped off, and the scraped ink is finally discharged from the discharge hole. When the fixed frame 5 rotates to the bottom of the bellows 10, the rack 22 also moves to the highest point of the track 8. After the ink is dried, the processing table 3 rotates again, and the rack 22 also descends along the surface of the track 8, and finally moves gradually from the inclined part of the track 8 to the horizontal part, and the fixed frame also falls back to the surface of the conveyor belt 4. Then the clamp releases the dried product. When the processing table 3 stops again, the staff can take the processed product out of the fixed frame 5.

[0053] Example 3

[0054] Reference Figure 1-8 This embodiment discloses a method for using an ink stacking system for a white cover plate, comprising the following steps:

[0055] S1: Start the printing system, place the substrate with the colored frame in the viewing area on the inner side of the fixed frame, and make it fall on the surface of the conveyor belt 4 to wait for processing. As the processing table rotates, the substrate is sent to the bottom of the printing device for printing;

[0056] S2: During printing, the first white ink printing boundary is pressed to the color frame by 0.25 mm, the second white ink printing boundary is flush with the color frame, the third white ink printing boundary is pressed to the color frame by 0.45 mm, and the fourth cover bottom ink printing boundary is pressed to the color frame by 0.,6 mm. The overall ink thickness is between 24-32 um;

[0057] S3: After the printing is completed, as the processing table rotates, the printed substrate is sent to the bottom of the drying device for drying. Before the substrate reaches the bottom of the drying device, the fixing frame is lifted up and separated from the surface of the conveyor belt. The conveyor belt also rotates accordingly, so that the ink on its surface is cleaned. Then, under the action of the drying device, the ink on the surface of the substrate is dried to obtain the final product.

[0058] S4: After drying, the fixed frame falls down with the rotation of the processing table until it falls on the surface of the conveyor belt again. Then the clamp releases the clamped product. When the processing table stops rotating again, the operator takes the product out from the inside of the fixed frame to complete the production.

[0059] Through the above steps, when the colored frame ink is printed on the opening in the viewing area, the overall visual effect can be improved while reducing the jagged edges and light leakage of the opening in the viewing area; the second white ink printing boundary is flush with the colored frame, which can reduce the height of the ink accumulation step at the colored frame; the third white ink printing is made into an overall white ink layer to prevent light leakage while avoiding the penetration of the bottom cover ink into the cover surface, and the overall ink thickness is uniform without the phenomenon of local excessive thickness.

[0060] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
