Description

Technical Field

[0001] This utility model relates to the field of glass coating, and in particular to a spraying mechanism for coating mobile phone glass. Background Technology

[0002] Mobile phone touchscreen glass is mainly used in mobile phone touchscreen panels. It is a chemically strengthened glass, and its raw material is a special sodium silicate glass material. Mobile phone glass comes in flat and curved versions. During production, a coating is applied to improve the surface properties of the glass.

[0003] A search of Chinese patents revealed publication number CN209669071U, which discloses a glass spraying device. The device includes a body with an internal roller conveyor. The roller conveyor has inlets and outlets on its side walls at both ends. The top of the roller conveyor has a spraying chamber, and the bottom has a hydraulic cylinder fixedly connected to the body. A support plate is located at the top of the hydraulic cylinder, and the top of the support plate holds the glass to be processed. A spraying mechanism is also located on the top of the support plate. This invention, through the setting of a baffle mechanism, not only positions the glass to be processed but also moves a glass baffle to the bottom of the glass. Therefore, when the spraying mechanism is performing spraying, the glass baffle will not be contaminated by the paint, preventing contamination of the side wall of the glass during subsequent positioning. Furthermore, the paint baffle catches any splashed paint, preventing paint from spraying onto the roller conveyor and contaminating the bottom surface of the glass during subsequent transport.

[0004] Existing spraying mechanisms have limited spraying methods. Generally, they use linear reciprocating spraying or fixed-angle oscillating spraying. Linear reciprocating nozzles are effective for flat glass, but poor for curved glass, making it difficult to achieve uniform coating. While fixed-angle oscillating spraying is effective for curved glass, it results in uneven coating on flat glass due to overlapping trajectories, leading to a thicker center and thinner edges. This affects the coating effect, making it inconvenient to use and difficult to apply to both flat and curved mobile phone glass, thus reducing its practicality and applicability. To solve the above problems, we propose a spraying mechanism for mobile phone glass coating. Utility Model Content

[0005] The purpose of this invention is to provide a spraying mechanism for coating mobile phone glass, which has the advantage of simultaneously possessing linear reciprocating spraying and fixed-angle oscillating spraying.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a spraying mechanism for mobile phone glass coating, including a fixed base, a groove at the bottom of the fixed base, a slider slidably connected to the inner wall of the groove, a screw threadedly connected to the inner wall of the slider, one end of the screw being rotatably connected to the inner wall of the fixed base, the other end of the screw being connected to a first motor via a coupling, the first motor being bolted to the surface of the fixed base, a fixed shell being bolted to the bottom of the slider, a second motor being bolted to the surface of the fixed shell, the output end of the second motor being connected to a reciprocating lead screw via a coupling, the other end of the reciprocating lead screw being rotatably connected to the inner wall of the fixed shell, a gear slidably connected to the surface of the reciprocating lead screw, a guide block rotatably connected to the inner wall of the gear, the guide block being slidably connected to the inner wall of the reciprocating lead screw, a gear meshing on the surface of the gear, a rotating shaft fixedly sleeved at the shaft center of the gear, and a U-shaped frame fixedly sleeved between the two ends of the rotating shaft.

[0007] By adopting the above technical solution, the first motor rotates to drive the screw, which moves the slider and causes the nozzle to move linearly for spraying. The second motor drives the reciprocating screw, which in turn drives the gear rack to rotate reciprocally, causing the nozzle to oscillate back and forth. This method sprays the mobile phone glass, thus achieving both linear reciprocating spraying and fixed-angle oscillating spraying, improving practicality and applicability, and making it convenient to use.

[0008] The present invention is further configured such that: a fixing block is bolted to the bottom of the U-shaped frame; a nozzle is slidably sleeved on the inner wall of the fixing block; a sliding cylinder is slidably sleeved on the surface of the fixing block; a spring is provided between the inner wall of the sliding cylinder and the inner wall of the fixing block; a trapezoidal groove is provided on the inner wall of the sliding cylinder; a steel ball is provided on the inner wall of the fixing block; and a snap-fit ​​groove is provided on the surface of the nozzle, and the snap-fit ​​groove snaps into the steel ball.

[0009] By adopting the above technical solution, the sliding cylinder moves, causing the trapezoidal groove to move. The movement of the trapezoidal groove allows the steel ball to enter the trapezoidal groove and disengage from the locking groove, thus removing the nozzle. This facilitates the disassembly and assembly of the nozzle, making it easier to replace and maintain the nozzle, improving its practicality and ease of use.

[0010] The present invention is further configured such that: both sides of the slider surface are bolted to the inner wall of the groove with a telescopic cover, and the screw is located inside the telescopic cover.

[0011] By adopting the above technical solution, the screw is protected by a telescopic cover, ensuring stable operation of the thread.

[0012] The present invention is further configured such that: a guide rod is bolted between the inner walls of the fixed shell, and the guide rod is slidably sleeved with the inner wall of the toothed rod.

[0013] By adopting the above technical solution, guide rods are installed to prevent the rack from shifting and ensure stability.

[0014] The present invention is further provided that the surface of the slide tube is provided with anti-slip texture.

[0015] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0016] The present invention is further configured such that a sealing gasket is provided between the nozzle and the inner wall of the fixing block.

[0017] By adopting the above technical solution, a sealing gasket is set to ensure airtightness.

[0018] The present invention is further configured such that: the surfaces of the fixed base and the fixed shell are both bolted with protective shells, and the first motor and the second motor are both located inside the protective shells.

[0019] By adopting the above technical solution, the first motor and the second motor are protected by setting up a protective shell.

[0020] The present invention is further configured such that a quick connector is connected to the top of the fixing block.

[0021] By adopting the above technical solution and setting a snap-fit ​​connector, it is easy to connect the paint pump.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model uses a first motor to drive a screw to move a slider, which in turn moves the nozzle in a straight line for spraying. A second motor drives a reciprocating screw to drive a gear rack to rotate back and forth, which in turn makes the nozzle swing back and forth. This method sprays the glass of a mobile phone, thus achieving both straight reciprocating spraying and fixed-angle swing spraying. This improves practicality and applicability, and makes the product convenient to use. 2. This utility model uses a movable sliding cylinder, which moves the trapezoidal groove, allowing the steel ball to enter the groove and disengage from the locking groove, thus removing the nozzle. This facilitates the disassembly and assembly of the nozzle, making it easier to replace and maintain, improving practicality and ease of use. Attached Figure Description

The first motor 5 rotates and drives the screw 4 to move the slider 3, causing the nozzle 15 to move linearly for spraying. The second motor 7 drives the reciprocating screw 8 to make the toothed rod 9 drive the gear 11 to rotate back and forth, causing the nozzle 15 to swing back and forth, thus spraying the mobile phone glass. This achieves both linear reciprocating spraying and fixed-angle swing spraying, improving practicality and applicability, and making it convenient to use.

[0027] refer to Figure 2 Both sides of the slider 3 surface are bolted to the inner wall of the slide groove 2 with telescopic covers 21, and the screw 4 is located inside the telescopic cover 21. By setting the telescopic cover 21, the screw 4 is protected and the thread is kept running stably.

[0028] refer to Figure 3 A guide rod 22 is bolted between the inner walls of the fixed shell 6 and the inner wall of the toothed rod 9. The guide rod 22 is slidably sleeved with the inner wall of the toothed rod 9. By setting the guide rod 22, the toothed rod 9 is prevented from deviating and stability is ensured.

[0029] refer to Figure 1 , Figure 2 and Figure 3 The surfaces of the fixed base 1 and the fixed shell 6 are bolted with protective shells 25, and the first motor 5 and the second motor 7 are both located inside the protective shells 25. By setting the protective shells 25, the first motor 5 and the second motor 7 are protected. Example

[0030] refer to Figure 1 and Figure 5 The bottom of the U-shaped frame 13 is bolted to a fixing block 14. A nozzle 15 is slidably fitted onto the inner wall of the fixing block 14. A slide cylinder 16 is slidably fitted onto the surface of the fixing block 14. A spring 17 is provided between the inner wall of the slide cylinder 16 and the inner wall of the fixing block 14. A trapezoidal groove 18 is provided on the inner wall of the slide cylinder 16. A steel ball 19 is provided on the inner wall of the fixing block 14. A snap-fit ​​groove 20 is provided on the surface of the nozzle 15, and the snap-fit ​​groove 20 snaps into the steel ball 19. By moving the slide cylinder 16, the slide cylinder 16 moves, causing the trapezoidal groove 18 to move. The movement of the trapezoidal groove 18 causes the steel ball 19 to enter the trapezoidal groove 18 and disengage from the snap-fit ​​groove 20, allowing the nozzle 15 to be removed. This facilitates the disassembly and assembly of the nozzle 15, making it easy to replace and maintain the nozzle 15, improving its practicality and ease of use.

[0031] refer to Figure 5 The surface of the slide cylinder 16 is provided with anti-slip texture 23. By setting the anti-slip texture 23, the hand slips and the operation is facilitated.

[0034] Brief description of operation: The first motor 5 rotates, driving the screw 4 to rotate. The screw 4 rotates, causing the slider 3 to move. The slider 3 moves, causing the fixed housing 6 to move the nozzle 15, enabling linear reciprocating spraying. The second motor 7 rotates, driving the reciprocating lead screw 8 to rotate. The reciprocating lead screw 8 rotates, causing the guide block 10 to move reciprocally. The guide block 10 moves reciprocally, causing the rack 9 to move reciprocally. The rack 9 moves reciprocally, causing the gear 11 to rotate reciprocally. The gear 11 rotates reciprocally, causing the rotating shaft 12 to rotate reciprocally. The rotating shaft 12 rotates reciprocally, causing the U-shaped frame 13 to swing reciprocally. The U-shaped frame 13 swings reciprocally, causing the nozzle 15 to swing reciprocally. By swinging the nozzle 15 reciprocally, it can simultaneously achieve linear reciprocating spraying. The purpose of the fixed-angle swing spraying is to move the slide cylinder 16 so that the trapezoidal groove 18 aligns with the steel ball 19, move the nozzle 15 outward, and move the nozzle 15 so that the locking groove 20 squeezes the steel ball 19, squeezing the steel ball 19 into the trapezoidal groove 18 and disengaging it from the locking groove 20. The nozzle 15 is then removed and replaced. The new nozzle 15 is installed in the fixing block 14. The slide cylinder 16 is released, and the slide cylinder 16, under the action of the spring 17, drives the trapezoidal groove 18 to reset. The reset of the trapezoidal groove 18 pushes the steel ball 19 into the locking groove 20, where it engages with the locking groove 20, thus fixing the nozzle 15 and completing the replacement. This achieves the purpose of facilitating the replacement of the nozzle 15.
