Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, specifically relating to a glass pretreatment device before coating. Background Technology

[0002] In glass coating processes, glass requires edge grinding and chamfering before coating. These processes are often independent of the coating process, and in practice, the glass needs to be clamped by fixtures during coating. Since the coating process typically involves high temperatures, if the glass edges are not precisely ground, stress concentration points or insufficient roughness may occur during high-temperature coating. This can lead to cracking during or after coating, severely impacting product quality, production efficiency, and increasing production costs. Furthermore, with the increasing market demand for flat glass coating, existing edge grinding and chamfering mechanisms typically process individual flat glass pieces at a time, which cannot adequately meet the need for rapid pre-treatment of flat glass before coating. Therefore, a new type of pre-treatment equipment for flat glass before coating is needed to overcome these problems. Summary of the Invention

[0036] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0037] Please see Figure 1-9 A pre-treatment device for glass before coating includes a conveying device 1, which includes a base 11. Lifting drive assemblies 12 are respectively installed on both sides of the base 11. Lateral drive assemblies 13 are respectively arranged on both sides of the feed end of the conveying device 1, with the two lifting drive assemblies 12 positioned between the two lateral drive assemblies 13. The distance between the lateral belts 138 of the two lateral drive assemblies 13 is adjustable to accommodate the conveying speed requirements of flat glass of different sizes. Downward drive assemblies 14 are respectively arranged on both sides of the other end of the conveying device 1, with the ends of the two downward drive assemblies 14 extending between the two lateral drive assemblies 13. An edge grinding device 2 and a chamfering device 3 are sequentially arranged on both sides of the conveying device 1 from the feed end. A photoelectric sensing device 4 is arranged between the edge grinding device 2 and the chamfering device 3 on the same side.

[0038] The base 11 extends upwards with several parallel support frames 15, all of which are positioned between two lifting drive components 12. Each support frame 15 has several linearly and evenly distributed support wheels 16 rotatably mounted on its top. During transport, a demonstration glass plate 5 is placed at the top feed end of the conveyor device 1, with the support wheels 16 assisting in lifting the glass plate 5. The distance between the two lateral belts 138 can be adjusted according to the width of the demonstration glass plate 5 to prevent it from moving in the non-conveying direction. When the demonstration glass plate 5 is transported to the junction of the lateral drive component 13 and the downward drive component 14, it begins to be pressed down and transported by the downward drive component 14 and the lifting drive component 12, ensuring that the demonstration glass plate 5 remains in the correct position during transport and preventing the glass from shifting during transport, which would affect the edge grinding and chamfering effects.

[0039] Each lifting drive assembly 12 is rotatably mounted on two lifting wheels 123 at both ends of the base 11, and the two lifting wheels 123 are jointly fitted with a lifting belt 125. A first drive motor 121 is fixedly mounted on the base 11, and a first drive wheel 122 is coaxially and fixedly connected to the output end of the first drive motor 121. The first drive wheel 122 and one of the lifting wheels 123 are jointly fitted with a first connecting belt 124. The first drive motor 121 drives the lifting belt 125 to rotate through the transmission of the first drive wheel 122, the first connecting belt 124, and the lifting wheel 123. The diameter of the first drive wheel 122 is smaller than the diameter of the lifting wheel 123, which facilitates the first drive motor 121 to amplify the output torque and reduce the output speed.

[0040] Each lateral drive assembly 13 includes a mounting base 131 fixedly connected to a base 11, with a horizontal slide 132 slidably connected to the top of the mounting base 131 via a groove. A horizontal screw 133 with a horizontal axis is threadedly connected to the side of the mounting base 131 away from the base 11, and the horizontal screw 133 is rotatably connected to the horizontal slide 132. A hexagonal nut is provided at one end of the horizontal screw 133 away from the horizontal slide 132, and an annular protrusion at the other end of the horizontal screw 133 is located within the inner cavity of the horizontal slide 132, which is rotatably connected to it. Turning the hexagonal nut of the horizontal screw 133 with a wrench drives the horizontal slide 132 to move, thereby adjusting the distance between the two lateral belts 138. Lateral wheels 136 are rotatably mounted at both ends of the horizontal slide 132, and the two lateral wheels 136 are fitted with the lateral belts 138. A second drive motor 134 is fixedly mounted on the top of the horizontal carriage 132. A second drive wheel 135 is coaxially fixedly connected to the output end of the second drive motor 134, and a second connecting belt 137 is fitted together on the second drive wheel 135 and one of the side wheels 136. The diameter of the second drive wheel 135 is smaller than the diameter of the side wheel 136, which facilitates the second drive motor 134 to amplify the output torque and reduce the output speed.

[0041] Each pressure drive assembly 14 includes a pressure frame 141 fixedly connected to a base 11. At least one vertical optical axis 142 is mounted inside the pressure frame 141. A lifting frame 146 is vertically slidably mounted inside the pressure frame 141, and the lifting frame 146 is slidably connected to the optical axis 142. A vertical stud 143 is rotatably mounted on the pressure frame 141, and the stud 143 is threadedly connected to the lifting frame 146. The stud 143 can only rotate along its own axis and cannot move linearly along its own axis. A worm gear 144 is coaxially fixedly sleeved on the top of the stud 143. The worm gear 144 meshes with a worm 145, and the worm 145 is rotatably connected to the pressure frame 141. The worm 145 can only rotate along its own axis and cannot move linearly along its own axis. The worm 145 can drive the worm gear 144 to rotate, but the worm gear 144 cannot drive the worm 145 to rotate. A hexagonal nut is provided at the end of the worm gear 145 away from the worm wheel 144.

[0042] The lifting frame 146 includes two rotatably mounted pressure rollers 149 at its two ends, and a pressure belt 151 is fitted around both pressure rollers 149. A third drive motor 147 is fixedly embedded in the lifting frame 146. A third drive wheel 148 is coaxially fixedly connected to the output end of the third drive motor 147. The third drive wheel 148 and one of the pressure rollers 149 are fitted together with a third connecting belt 150. The diameter of the third drive wheel 148 is smaller than the diameter of the pressure roller 149, which facilitates the third drive motor 147 to amplify the output torque and reduce the output speed.

[0043] Using a wrench to turn the hexagonal nut of the worm gear 145, the worm gear 145 drives the stud 143 to rotate through the worm wheel 144 that meshes with it. The rotating stud 143 drives the lifting frame 146 to move up and down along the optical axis 142, thereby realizing the height adjustment of the pressure belt 151.

[0044] The first drive motor 121, the second drive motor 134, and the third drive motor 147 are all servo motors, which are synchronously driven to transport the demonstration glass panel 5 through existing software and hardware control. The lifting belt 125, the side belt 138, and the pressing belt 151 are all made of wear-resistant rubber with anti-slip textures on the surface, which can stably transport the demonstration glass panel 5.

[0045] Each edging device 2 includes a first fixed base 21 fixedly connected to a base 11. A first adjusting screw 22 with its axis perpendicular to the glass conveying direction is rotatably mounted on the first fixed base 21. A first horizontal slide 23 is horizontally slidably mounted inside the first fixed base 21, and the first horizontal slide 23 is threadedly connected to the first adjusting screw 22. A hexagonal nut is provided at the end of the first adjusting screw 22 extending out of the first fixed base 21. A vertical second adjusting screw 24 is rotatably mounted on the first horizontal slide 23. A first mounting platform 25 is vertically slidably mounted inside the first horizontal slide 23, and the first mounting platform 25 is threadedly connected to the second adjusting screw 24. A hexagonal nut is provided at the end of the second adjusting screw 24 extending out of the first horizontal slide 23. An edging assembly 26 is mounted on the end of the first mounting platform 25 extending horizontally towards the conveying device 1.

[0046] The edge grinding assembly 26 consists of an edge grinding motor 261 and an edge grinding wheel 262. The edge grinding motor 261 is a high-speed motor with a power of 0.75kW, and its speed can be precisely adjusted between 2800-3500 rpm via a matching speed controller to adapt to the edge grinding requirements of different hardnesses and flat glass materials. The edge grinding wheel 262 is mounted on the output shaft of the edge grinding motor 261. The edge grinding wheel 262 uses a high-strength diamond grinding wheel, which can effectively grind the edges of the flat glass.

[0047] By using a wrench to turn the hexagonal nuts of the first adjusting screw 22 and the second adjusting screw 24, the position of the grinding wheel 262 can be moved horizontally and vertically, so that the grinding wheel 262 can be in contact with the edge of the glass for grinding.

[0048] The edging device 2 is also equipped with an auxiliary spray assembly (not shown in the attached embodiment). The spray assembly consists of a spray pipe, multiple nozzles, and a support. The spray assembly is also equipped with a cooling water system. The support is mounted on the protective cover of the edging device 2 (not shown in the attached embodiment), ensuring that the nozzles are positioned close to the contact area between the edging wheel 262 and the glass edge. The spray pipe is connected to an external water source, and the multiple nozzles are evenly distributed on the pipe in a fan-shaped spray angle design, capable of fully covering the edging area. During the edging process, the spray device is activated, and high-pressure water jets are sprayed from the nozzles, quickly washing away the grinding powder generated during edging, preventing grinding powder from remaining or re-adhering to the glass surface, affecting the edging quality and subsequent coating effect. Simultaneously, the water flow also cleans the edging wheel 262, further ensuring its normal operation.

[0049] Each chamfering device 3 includes a second fixed base 31 fixedly connected to the base 11. A third adjusting screw 32, with its axis perpendicular to the glass conveying direction, is rotatably mounted on the second fixed base 31. An adjusting motor 37, with its output end coaxially fixedly connected to the third adjusting screw 32, is mounted on the second fixed base 31. A second horizontal slide block 33 is horizontally slidably mounted inside the second fixed base 31, and the second horizontal slide block 33 is threadedly connected to the third adjusting screw 32. A vertical fourth adjusting screw 34 is rotatably mounted on the second horizontal slide block 33. A second mounting platform 35 is vertically slidably mounted inside the second horizontal slide block 33, and the second mounting platform 35 is threadedly connected to the fourth adjusting screw 34. A hexagonal nut is provided at the end of the fourth adjusting screw 34 extending out of the second horizontal slide block 33. A chamfering assembly 36 is mounted on the end of the second mounting platform 35 extending horizontally towards the conveying device 1. The chamfering device 3 also has an auxiliary spray assembly, which functions similarly to the spray assembly of the edge grinding device 2.

[0050] The thread helix angles (which can be understood as the slope of an inclined plane) of the first adjusting screw 22, the second adjusting screw 24, and the fourth adjusting screw 34 are small enough that the friction between the threads is sufficient to prevent the screws from rotating in the opposite direction under axial force. That is, the object driven by the adjusting screws cannot drive the adjusting screws to rotate in any direction. The adjusting motor 37 is a servo motor that can drive or fix the third adjusting screw 32.

[0051] The chamfering assembly 36 consists of a chamfering motor 361 and a chamfering wheel 362. The chamfering motor 361 is a high-speed motor with a power of 0.75KW, maintaining a speed of 2800-3500 rpm to ensure that the chamfering wheel 362 can rotate at high speed to efficiently chamfer the edges of the flat glass. The chamfering wheel 362 is mounted on the output shaft of the chamfering motor 361 and features a specific tapered design to meet different chamfering requirements.

[0052] By turning the hexagonal nut of the fourth adjusting screw 34 with a wrench, the chamfering wheel 362 can be moved up and down, so that the chamfering wheel 362 can be beveled against the edge of the glass.

[0053] The photoelectric sensing device 4 includes a transmitting device 41 and a receiving device 42, which are respectively installed below the glass plate conveying channel and above the glass plate conveying channel.

[0054] The photoelectric sensor 4 is used to sense the edge position of the flat glass. When the demonstration glass plate 5 is conveyed below the chamfering device 3, the photoelectric sensor 4 detects the glass edge and triggers the translation drive device. The translation drive device consists of an adjusting motor 37, a second fixed base 31, and a third adjusting screw 32. The adjusting motor 37 drives the chamfering motor 361 and the chamfering wheel 362 mounted on it to reciprocate linearly along a direction perpendicular to the conveying direction of the conveying device 1. By controlling the running time of the adjusting motor 37, the forward and backward distance of the chamfering wheel 362 is controlled, thereby achieving different sizes of chamfering effects. For example, when a smaller chamfer is needed, the adjusting motor 37 drives the chamfering wheel 362 forward a shorter distance and quickly retracts; when a larger chamfer is needed, the driving time of the adjusting motor 37 is extended, increasing the forward distance of the chamfering wheel 362. This method based on photoelectric sensing and precise time control greatly improves the accuracy and efficiency of chamfering.

[0055] Working principle:

[0056] First, based on the width of the flat glass to be processed (i.e., demonstration glass panel 5), adjust the distance between the two lateral belts 138 to match the width of the flat glass. Adjust the vertical height difference between the pressing belt 151 and the supporting belt 125 to match the thickness of the flat glass. Then, based on the thickness of the flat glass, turn the second adjusting screw 24 of the edging device 2 and the fourth adjusting screw 34 of the chamfering device 3 to adjust the height of the edging wheel 262 and the chamfering wheel 362, ensuring a suitable distance between them and the upper surface of the flat glass. Simultaneously, based on the glass material and hardness, set the speed of the edging motor 261 using the speed controller, turn on the cooling water system and adjust the flow rate and position of the cooling water nozzles, and turn on the spray assembly of the edging device 2 and adjust the nozzle angle and water pressure. Precise initial adjustments lay the foundation for subsequent high-quality edging, chamfering, and coating processes.

[0057] The drive motor of conveyor 1 is turned on, and the lifting belt 125, side belt 138, and downward belt 151 begin operation. The flat glass is placed on the lifting belt 125, and the flat glass moves forward under its drive. The side belt 138 and downward belt 151 assist the lifting belt 125 in controlling the linear movement of the flat glass. When the flat glass reaches the side of the edge grinding device 2, the edge grinding motor 261 is turned on, and the edge grinding wheel 262 rotates at high speed to grind the edge of the flat glass. During this time, the spray assembly continues to work, washing away the grinding powder, completing the edge grinding operation. Stable conveying and efficient edge grinding ensure a smooth and even glass edge, providing a good foundation for coating.

[0058] The flat glass, after being edge-ground, continues to be conveyed forward to the chamfering device 3. Once the photoelectric sensor 4 detects the glass edge, it triggers the translation drive to operate. Based on the preset chamfer size, the running time of the adjustable motor 37 is controlled to make the rotating chamfering wheel 362 move forward and backward to complete the corresponding chamfering process. Simultaneously, the spray unit of the chamfering device 3 is activated and the water flow parameters are adjusted. Appropriate chamfering further optimizes the glass edge condition and improves the overall performance of the coated glass.

[0059] Throughout the processing, operators can observe the equipment's operation and the quality of the processed glass, and adjust parameters such as conveyor speed, grinding wheel 262 height, grinding motor 261 speed, cooling water flow rate, spray assembly water flow parameters, chamfering wheel 362 height, translation drive motor running time, and spray unit water flow parameters in a timely manner to ensure the production of flat glass products that meet requirements. Real-time monitoring and adjustment guarantee the quality of edge grinding and chamfering, thereby ensuring the quality of the coated glass.

[0060] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
