Description

Technical Field

[0001] This utility model belongs to the field of tempered glass coating technology, specifically relating to a coating device for curved tempered glass. Background Technology

[0002] The curved structure of curved tempered glass can easily lead to edge stress concentration, optical distortion, and cleaning difficulties. To improve its performance, a functional film layer needs to be coated on its surface using a coating device. This is to meet the needs of consumer electronics, automotive, and construction industries for curved tempered glass while solving problems such as coating uniformity, clamping damage, and production efficiency caused by the curved geometry.

[0003] Chinese patent document CN219526499U discloses a coating device for curved tempered glass. On one side of a rotating disk that rotates due to the operation of a drive motor and moves horizontally due to the operation of a cylinder, there are multiple sliding blocks that can be inserted into the annular convex grooves of the rotating disk, and fixed sleeves that are threadedly connected to the sliding blocks. This allows the operator to adjust the friction between the fixed sleeves and the rotating disk according to the curvature of the curved glass, thereby changing the position of the fixed sleeves in contact with and clamping the curved glass. In this way, the curved glass is clamped and coated by multiple fixed sleeves that can move around their axes along the convex grooves between the two rotating disks.

[0004] However, in the existing technology, the clamping method used in the coating device requires multiple fixing sleeves to simultaneously press against the convex and concave surfaces of the glass to achieve a stable clamping. When only one side (such as the convex or concave surface) needs to be coated, this double-sided contact structure will block the area to be coated, resulting in incomplete and uneven film coverage. In addition, the clamping also requires adjusting and locking the position of each fixing sleeve to adapt to different curvatures. This process is cumbersome and time-consuming, which will significantly reduce the coating efficiency. Therefore, a coating device for curved tempered glass is proposed. Utility Model Content

[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0031] like Figures 1-5 As shown, a coating device for curved tempered glass includes a coating component 1 that can be placed into curved tempered glass for on-demand coating, a material placement component 2 that can be easily adapted to curved tempered glass is provided in the coating component 1, and a positioning component 3 that can adsorb and fix the curved tempered glass at multiple points is provided on the material placement component 2.

[0032] In this embodiment: the coating assembly 1 includes a frame 101, anti-tilt ropes 102 are provided on both sides of the frame 101, a lifting frame 103 is movably installed inside the frame 101, anti-detachment covers 104 are fixedly connected to the front and rear of the lifting frame 103, vertical hydraulic cylinders 105 are fixedly connected to the front and rear ends of the lifting frame 103, and a coating machine 106 is fixedly installed on the lifting frame 103 between the two vertical hydraulic cylinders 105. The lifting frame 103 and the anti-detachment covers 104 are slidably connected to the frame 101.

[0033] The frame 101 provides installation positions for components such as the vertical hydraulic cylinder 105, shaft seat 201, drive unit 204, and pump 308. The anti-tilt rope 102 improves the overall stability of the frame 101, especially preventing the vertical frame from tilting or shifting. The lifting frame 103, which rises and falls due to the operation of the vertical hydraulic cylinder 105, installs and drives the coating machine 106 to rise and fall. The anti-detachment cover 104 improves the stability of the sliding of the lifting frame 103 relative to the frame 101. The coating machine 106, which consists of spraying, curing and other units, coats the curved tempered glass placed on the positioning component 3 as needed. The structure and function of the coating machine 106 are known prior art in this field, so they will not be described in detail.

[0034] In this embodiment: the material placement component 2 includes a rotating component that can switch the position of the curved tempered glass to be coated, and a positioning component that can fully fix the positioning component 3 to the curved tempered glass according to the coating requirements and specifications of the curved tempered glass.

[0035] The rotating component includes a bearing seat 201 fixedly installed in the front and rear of the frame 101, a rotating shaft 202 movably installed in the bearing seat 201, a rotating frame 203 fixedly connected between the two rotating shafts 202, and a drive unit 204 fixedly connected to the rear of one of the rotating shafts 202. The shifting component includes a reversing frame 205 movably connected to both sides of the rotating frame 203, a double-acting hydraulic cylinder 206 fixedly installed under the rotating frame 203, a slide block 207 fixedly connected to each telescopic end of the double-acting hydraulic cylinder 206, a plug rod 208 provided between the rotating frame 203 and the slide block 207, and a connecting rod 209 provided between adjacent reversing frames 205 and slide blocks 207.

[0036] The bearing seat 201 is rotatably connected to the rotating shaft 202. The rotating shaft 202 is coaxial with the bearing seat 201 and passes through it. The rotating frame 203 has limiting grooves on both sides that fit and pass through the two ends of the insertion rod 208. The rotating frame 203 and the connecting rod 209 are rotatably connected to the reversing frame 205. The slide 207 and the insertion rod 208 are slidably connected to the rotating frame 203. The slide 207 is rotatably connected to the connecting rod 209. The reversing frame 205 has a first insertion hole at the front and rear, and a second insertion hole on the side of the reversing frame 205 away from the rotating frame 203. The axes of the adjacent first insertion hole and second insertion hole are perpendicular to each other.

[0037] The rotating frame 203 is mounted on the rotating shaft 202 whose movable range is limited by the bearing 201, so that the rotating frame 203 can rotate around the axis of the rotating shaft 202 under the action of external force. The driving unit 204, which can be composed of a motor, reducer, etc., drives the rotating frame 203 to rotate as needed when outputting power to the connected rotating shaft 202. The reversing frame 205, which can rotate relative to the rotating frame 203, provides the installation position for components such as the bracket 303. The slide 207, whose movable range is limited by the insert rod 208 and the rotating frame 203, synchronously transmits the length change of the extension end of the double-acting hydraulic cylinder 206 to the connecting rod 209 connected to it, and then the connecting rod 209 transmits it to the reversing frame 205 connected to it, so that the double-acting hydraulic cylinder 206 after operation can drive the reversing frame 205 to rotate relative to the rotating frame 203.

[0038] In this embodiment: the positioning component 3 includes a hollow platform 301 fixedly connected to the side of the rotating frame 203. A plurality of first suction cups 302 are provided on the hollow platform 301. A bracket 303 is fixedly installed on the reversing frame 205. A plurality of ball joints 304 are provided on the bracket 303. A second suction cup 305 is fixedly connected to the upper end of the ball joint 304. Positioning bolts 306 that are threadedly connected to the reversing frame 205 are provided at the front and rear ends of the bracket 303. A connecting pipe 307 is provided between the hollow platform 301 and each of the second suction cups 305. A pump 308 is fixedly installed at the front of the frame 101. A suction pipe 309 is provided between the hollow platform 301 and the pump 308.

[0039] Both the first and second insertion holes are aligned with the positioning bolts 306. Multiple first suction cups 302 are arranged at equal intervals along the length of the hollow platform 301, and multiple ball joints 304 are arranged at equal intervals along the length of the bracket 303.

[0040] The hollow platform 301, equipped with a first suction cup 302 and connected to a connecting pipe 307, injects or draws air into the first suction cup 302 and connecting pipe 307 when the hollow area inside is under positive or negative pressure, respectively. The orientation of the second suction cup 305 can be independently adjusted within a certain range through the ball joint 304 installed on the bracket 303. The bracket 303 is fixedly installed on the corresponding position on the reversing frame 205 by the positioning bolts 306 inserted into the first or second insertion hole of the reversing frame 205. The connecting pipe 307 forms a gas flow channel between the hollow platform 301 and the second suction cup 305. The pump 308, which has functions such as suction and exhaust, can adjust the internal air pressure of the hollow platform 301 through the suction pipe 309.

[0041] Working Principle: When this device is installed for coating curved tempered glass, the positions of the reversing frame 205 and the bracket 303 on the reversing frame 205 can be adjusted according to the single-sided coating requirements of the curved tempered glass. If coating is required on the convex side, the operation of the double-acting hydraulic cylinder 206 can cause the two reversing frames 205 to rotate synchronously at a certain angle below the rotating frame 203. According to the curvature of the curved tempered glass, by inserting the positioning bolt 306 into the appropriate hole on the reversing frame 205, when the curved tempered glass is placed on the positioning component 3 with the convex side facing up, the highest point of its concave surface can be located on the first suction cup 302, while the second suction cup 305 can be positioned below the first suction cup 302, fully contacting other parts of the concave surface of the curved tempered glass. Then, by operating the pump 308, the first suction cup 302 and the second suction cup 305 form a negative pressure to firmly adsorb and fix the curved tempered glass. Conversely, if the concave surface needs to be coated, when the curved tempered glass is placed on the positioning component 3 with the concave surface facing upward, the lowest point of its convex surface contacts the first suction cup 302, while the second suction cup 305 is at a position higher than the first suction cup 302, fully contacting other parts of the convex surface of the curved tempered glass and adsorbing and fixing it.

[0042] After the curved tempered glass is fixed, the vertical hydraulic cylinder 105, coating machine 106, and drive unit 204 can be controlled to operate. The coating machine 106, after operation, can coat the curved tempered glass that can rotate with the rotating frame 203 under variable height. This allows the curved tempered glass to be positioned directly below the coating machine 106. While maintaining a relatively fixed distance from the coating machine 106, uniform coating can be completed sequentially. After coating, the glass rotates back to the starting position with the rotating frame 203 so that the operator can remove it. At the same time, it prevents the connecting pipe 307 and the pulling pipe 309 from getting tangled or overstretched due to excessive unidirectional rotation of the rotating frame 203.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
