Description

Technical Field

[0001] This invention belongs to the field of AG glass etching technology, specifically a fully automatic AG glass etching device. Background Technology

[0002] AG glass, also known as anti-reflective glass and anti-glare glass, is made by transforming the originally smooth reflective surface of glass into a matte refractive surface, making the glass surface uneven and reducing the reflectivity of the glass surface. When etching AG glass, a layer of paraffin wax is first applied to the etching surface, then a pattern is engraved on the paraffin wax with a tool, and then hydrofluoric acid is applied on top to obtain the glass etching pattern.

[0003] In current glass etching processes, etching solution is sprayed from an etching nozzle into a patterned groove drawn on paraffin wax. The nozzle is then moved by a movable component, gradually filling the groove with etching solution. After a certain period, the etching solution is removed, completing the glass etching. However, in actual etching, the contact time between the glass and the etching solution within the groove varies, resulting in different degrees of corrosion within the same time frame. This leads to variations in the degree of etching at different locations within the groove upon completion, affecting the overall etching quality.

[0004] Therefore, the present invention provides a fully automatic glass AG etching device. Summary of the Invention

A rectangular frame is provided between the storage box and the support frame, and the projection of the rectangular frame covers the glass to be etched mounted on the support frame; a pair of first telescopic rods are installed on the side of the rectangular frame based on central symmetry, and a first linkage frame is provided at the output end of the first telescopic rods. A partition is provided at the end of the first linkage frame away from the output end of the first telescopic rods, and the top surface of the partition is attached to the bottom surface of the rectangular frame. When the pair of partitions are connected, they seal the bottom end of the rectangular frame; a support member is provided on the side of the rectangular frame.

[0007] Preferably, the support includes a second telescopic rod and a second linkage frame. The second telescopic rod is installed on the side of the workbench, and one end of the second linkage frame is installed at the output end of the second telescopic rod, and the other end is installed on the side of the rectangular frame.

[0008] Preferably, the top surface of the support frame is provided with a receiving plate, and a baffle is provided around the top boundary of the receiving plate, and a through hole is provided inside; the boundary of the through hole is attached to the bottom surface of the glass to be etched after installation; a connector is provided between the side of the receiving plate and the storage box.

[0009] Preferably, the connector includes a pump and a return pipe; one end of the return pipe passes through a baffle plate set at the top boundary of the receiving plate, and the other end is connected to the input end of the pump; the pump is installed on the surface of the storage tank and its output end passes through the storage tank; a one-way valve with the valve port facing upward is provided inside the return pipe.

[0010] Preferably, a strip-shaped jet nozzle is provided on one side of the rectangular frame, and the nozzle of the strip-shaped jet nozzle points towards the top surface of the glass to be etched; a first air pump is provided on the side of the strip-shaped jet nozzle, and the air outlet of the first air pump is in communication with the strip-shaped jet nozzle.

[0011] Preferably, a protective plate is provided on the top surface of the baffle at the top boundary of the receiving plate.

[0012] Preferably, a sealing gasket is provided between the receiving plate and the glass to be etched.

[0013] Preferably, a second air pump is provided on the top surface of the support frame, and a rectangular jet head is provided on the inner wall of the through hole of the receiving plate; the nozzle of the rectangular jet head points to the position between the bottom surface of the glass to be etched and the sealing gasket, and multiple air pipes are provided between the output end of the second air pump and the rectangular jet head.

[0014] Preferably, the top surface of the partition is provided with a compression frame, the end of the compression frame away from the partition is located outside the rectangular frame, and multiple elastic sheets are horizontally arranged on the side of the rectangular frame.

[0015] Preferably, the elastic sheet has a protrusion on its side, a rubber block is provided below the protrusion, and a connecting rope is provided between the rubber block and the protrusion; initially, the surface of the rubber block is in contact with the side of the elastic sheet.

[0016] The beneficial effects of this invention are as follows: 1. The fully automatic glass AG etching device of the present invention, by setting a rectangular frame, releases the etching solution inside the storage tank into the rectangular frame below through the outlet pipe during use. Then, the first telescopic rod is controlled to move the partition through the first linkage frame, so that the partition releases the seal on the bottom surface of the rectangular frame. Then, the etching solution in the rectangular frame is quickly released into the top surface of the glass below, and then quickly fills the tank of the pattern engraved by paraffin on the top surface of the glass. After etching for a certain period of time, the etching solution in the tank is removed, and the etching is completed. In the above etching process, the pattern tank is quickly filled with etching solution, and the etching solution in different positions has the same viewing time area on the glass. Therefore, the etching degree of different positions is unlikely to be different in the same time, ensuring the quality of etching.

The fully automatic glass AG etching device of the present invention, before releasing the etching liquid held in the rectangular frame onto the glass surface, controls the second telescopic rod to move the rectangular frame downward through the second linkage frame, reducing the distance between the bottom surface of the rectangular frame and the glass. Therefore, when releasing the etching liquid in the rectangular frame, it prevents the etching liquid from falling into the top surface of the glass with excessive impact force and causing splashing, thereby improving the stability of the etching process.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown, an embodiment of the present invention provides a fully automatic glass AG etching device, including a worktable 1, a support frame 11 on the top surface of the worktable 1 for supporting the glass to be etched; a connecting frame on the side of the support frame 11, a support plate 2 at the top of the connecting frame, a storage box 21 on the bottom surface of the support plate 2, and a liquid outlet pipe with the opening facing downward on the side of the storage box 21. A rectangular frame 3 is provided between the storage box 21 and the support frame 11. The projection of the rectangular frame 3 covers the glass to be etched, which is mounted on the support frame 11. A pair of first telescopic rods 32 are centrally symmetrically installed on the side of the rectangular frame 3. A first linkage frame 33 is provided at the output end of the first telescopic rod 32. A partition plate 31 is provided at the end of the first linkage frame 33 away from the output end of the first telescopic rod 32. The top surface of the partition plate 31 is attached to the bottom surface of the rectangular frame 3. When the pair of partition plates 31 are connected, they seal the bottom end of the rectangular frame 3. Support members are provided on the side of the rectangular frame 3. In this embodiment of the invention, the glass to be etched is placed on the top surface of the support frame 11. Then, the etching solution inside the storage box 21 is released into the rectangular frame 3 below through the outlet pipe. The etching solution is received by a pair of partitions 31 set on the bottom surface of the rectangular frame 3. Then, the first telescopic rod 32 is controlled, and the first telescopic rod 32 drives the partitions 31 to move through the first linkage frame 33, so that the partitions 31 release the blockage on the bottom surface of the rectangular frame 3. Then, the etching solution in the rectangular frame 3 is quickly released to the top surface of the glass below, and then quickly fills the groove of the pattern engraved by paraffin on the top surface of the glass. After etching for a certain period of time, the etching solution in the groove is removed, and the etching is completed. In the above etching process, the pattern groove is quickly filled with etching solution, and the etching solution in different positions has the same viewing time area on the glass. Therefore, the etching degree of different positions is unlikely to be different in the same time, ensuring the quality of etching.

[0023] The support components include a second telescopic rod 4 and a second linkage frame 41. The second telescopic rod 4 is installed on the side of the worktable 1. One end of the second linkage frame 41 is installed at the output end of the second telescopic rod 4, and the other end is installed on the side of the rectangular frame 3. Before releasing the etching solution held in the rectangular frame 3 onto the glass surface, the second telescopic rod 4 is controlled to drive the rectangular frame 3 downward through the second linkage frame 41. The distance between the bottom surface of the rectangular frame 3 and the glass is reduced. Therefore, when releasing the etching solution in the rectangular frame 3, it is prevented that the etching solution falls into the top surface of the glass with excessive impact force, causing splashing and improving the stability of the etching process.

[0024] like Figures 3 to 8 As shown, a receiving plate 5 is provided on the top surface of the support frame 11. A baffle is provided around the top boundary of the receiving plate 5, and a through hole is provided inside. The boundary of the through hole is attached to the bottom surface of the glass to be etched after installation. A connector is provided between the side of the receiving plate 5 and the storage box 21. When the etching liquid in the rectangular frame 3 is released onto the glass surface, the etching liquid flowing out of the glass surface falls into the top surface of the receiving plate 5. By being blocked by the baffle provided at the boundary of the top surface of the receiving plate 5, the etching liquid will stay on the top surface of the receiving plate 5, realizing the collection of the etching liquid flowing out from the top surface of the glass, which is conducive to centralized processing by the staff.

[0025] The connecting components include a liquid pump 53 and a return pipe 52; one end of the return pipe 52 passes through a baffle set at the top boundary of the receiving plate 5, and the other end is connected to the input end of the liquid pump 53; the liquid pump 53 is installed on the surface of the storage tank 21 and its output end passes through the storage tank 21; a one-way valve with the valve port facing upward is provided inside the return pipe 52; when the etching solution is concentrated on the top surface of the receiving plate 5, the liquid pump 53 is started, and the liquid pump 53 draws the etching solution on the top surface of the receiving plate 5 into the storage tank 21 through the return pipe 52, so as to realize the automatic recycling of the etching solution.

[0026] A strip-shaped jet nozzle 6 is provided on one side of the rectangular frame 3, with the nozzle of the strip-shaped jet nozzle 6 pointing towards the top surface of the glass to be etched; a first air pump 61 is provided on the side of the strip-shaped jet nozzle 6, with the air outlet of the first air pump 61 communicating with the strip-shaped jet nozzle 6; when the etching solution inside the rectangular frame 3 has completely fallen into the top surface of the glass, the first air pump 61 is activated, and the first air pump 61 inflates the strip-shaped jet nozzle 6, which sprays airflow through the nozzle towards the top surface of the glass. The airflow acts on the etching solution remaining on the top surface of the glass, accelerating the flow of the etching solution from the top surface of the glass to the top surface of the receiving plate 5, which is beneficial to the collection process of the etching solution.

[0027] A protective plate 62 is provided on the top surface of the baffle at the top boundary of the receiving plate 5; when the strip jet head 6 drives the etching liquid on the top surface of the glass to fall off through the airflow, the protective plate 62 will block the airflow movement and prevent the airflow from carrying the etching liquid to fall onto the outside of the receiving plate 5.

[0028] A sealing gasket 51 is provided between the receiving plate 5 and the glass to be etched; this prevents the etching solution on the top surface of the receiving plate 5 from flowing into the through hole through the gap between it and the glass plate, thus preventing leakage. It should be noted that the existence of the through hole facilitates the fixed support of the support frame 11 for the glass to be etched.

[0029] A second air pump 7 is installed on the top surface of the support frame 11, and a rectangular jet nozzle 71 is installed on the inner wall of the through hole of the receiving plate 5. The nozzle of the rectangular jet nozzle 71 is directed between the bottom surface of the glass to be etched and the sealing gasket 51. Multiple air pipes are installed between the output end of the second air pump 7 and the rectangular jet nozzle 71. When working, the second air pump 7 is started, and the second air pump 7 inflates the rectangular jet nozzle 71 through the air pipes. The airflow from the rectangular jet nozzle 71 is directed between the bottom surface of the glass to be etched and the sealing gasket 51. When the sealing gasket 51 is viewed from too low, the sealing effect decreases, and the airflow will enter the top surface of the receiving plate 5 through the gap between the bottom surface of the glass to be etched and the sealing gasket 51. The etching liquid received on the top surface of the receiving plate 5 will bubble and rise upward, thus reminding the staff to replace the sealing gasket 51.

[0030] like Figure 2 As shown, a pressing frame 8 is provided on the top surface of the partition 31. The end of the pressing frame 8 away from the partition 31 is located outside the rectangular frame 3. Multiple elastic sheets 81 are horizontally arranged on the side of the rectangular frame 3. The pressing frame 8 can press the elastic sheets 81 as the partition 31 moves. When the partition 31 moves, the partition 31 drives the pressing frame 8 to move synchronously. The end of the pressing frame 8 located outside the rectangular frame 3 intermittently presses the elastic sheets 81, causing the elastic sheets 81 to oscillate, which in turn drives the entire rectangular frame 3 to oscillate, accelerating the shedding of the etching solution remaining on the surface of the rectangular frame 3 and optimizing the etching efficiency.

[0031] The elastic sheet 81 has a protrusion 82 on its side, and a rubber block 83 is provided below the protrusion 82. A connecting rope is provided between the rubber block 83 and the protrusion 82. Initially, the surface of the rubber block 83 is in contact with the side of the elastic sheet 81. When the elastic sheet 81 oscillates, the oscillation force will cause the side rubber block 83 to shake. When the partition 31 stops moving, the rubber block 83 will continuously hit the elastic sheet 81 on one side through the action of the connecting rope, thereby delaying the oscillation time of the elastic sheet 81, which is beneficial to the removal of the etching solution remaining on the surface of the rectangular frame 3.

[0032] During operation, the glass to be etched is placed on the top surface of the support frame 11. Then, the etching solution inside the storage tank 21 is released through the outlet pipe into the rectangular frame 3 below. A pair of partitions 31 on the bottom surface of the rectangular frame 3 receive the etching solution. Next, the first telescopic rod 32 is controlled, and through the first linkage frame 33, it moves the partitions 31, causing them to release the seal on the bottom surface of the rectangular frame 3. The etching solution inside the rectangular frame 3 is then quickly released onto the top surface of the glass, rapidly filling the groove with the pattern engraved on the paraffin wax. After etching for a certain period, the groove is then... The etching solution inside is removed, and the etching is completed. In the above etching process, the pattern tank is quickly filled with etching solution. The etching solution in different positions has the same viewing time area on the glass, so the etching degree in different positions is unlikely to be different in the same time, ensuring the quality of etching. Before releasing the etching solution held in the rectangular frame 3 onto the glass surface, the second telescopic rod 4 is controlled to drive the rectangular frame 3 downward through the second linkage frame 41. The distance between the bottom surface of the rectangular frame 3 and the glass is reduced. Therefore, when releasing the etching solution in the rectangular frame 3, it is prevented that the etching solution falls into the top surface of the glass with too great impact force and splashes, thus improving the stability of the etching process.

[0033] When the etching solution within the rectangular frame 3 is released onto the glass surface, the etching solution flowing out of the glass surface falls onto the top surface of the receiving plate 5. The baffles at the boundary of the top surface of the receiving plate 5 prevent the etching solution from reaching the top surface, thus collecting the etching solution flowing out of the glass surface and facilitating centralized processing by staff. When the etching solution accumulates on the top surface of the receiving plate 5, the pump 53 is activated. The pump 53 draws the etching solution from the top surface of the receiving plate 5 into the storage tank 21 through the return pipe 52, achieving automatic recycling of the etching solution. When the etching solution inside the rectangular frame 3 has completely fallen onto the top surface of the glass, the first air pump 61 is activated. The first air pump 61 inflates the strip-shaped jet nozzle 6, which sprays airflow through the nozzle onto the top surface of the glass. The airflow acts on the remaining etching solution on the top surface of the glass, accelerating the flow of the etching solution from the top surface of the glass to the top surface of the receiving plate 5, which is beneficial to the collection process of the etching solution. When the strip-shaped jet nozzle 6 drives the etching solution off the top surface of the glass through airflow, the protective plate 62 will block the airflow movement to prevent the airflow from carrying the etching solution onto the outside of the receiving plate 5.

[0034] To prevent the etching solution on the top surface of the receiving plate 5 from flowing into the through hole through the gap between it and the glass plate, thus avoiding leakage, it should be noted that the existence of the through hole facilitates the fixed support of the support frame 11 for the glass to be etched. During operation, the second air pump 7 is activated, and it inflates the rectangular jet head 71 through the air pipe. The rectangular jet head 71 sprays air towards the area between the bottom surface of the glass to be etched and the sealing gasket 51. When the sealing gasket 51 is viewed from too low, the sealing effect decreases, and the airflow can enter the top surface of the receiving plate 5 through the gap between the bottom surface of the glass to be etched and the sealing gasket 51. This causes bubbles to rise from the top surface of the receiving plate 5, thus alerting the operator to the process. Personnel replace the sealing gasket 51; when the partition 31 moves, the partition 31 drives the extrusion frame 8 to move synchronously. The extrusion frame 8 is located at one end of the rectangular frame 3 and intermittently extrudes the elastic sheet 81, causing the elastic sheet 81 to oscillate, which in turn drives the entire rectangular frame 3 to oscillate, accelerating the removal of residual etching solution from the surface of the rectangular frame 3; optimizing etching efficiency; when the elastic sheet 81 oscillates, the oscillation force will cause the side rubber block 83 to shake. When the partition 31 stops moving, the rubber block 83 continuously impacts the elastic sheet 81 on one side through the action of the connecting rope, thereby delaying the oscillation time of the elastic sheet 81, which is beneficial to the removal of residual etching solution from the surface of the rectangular frame 3.
