Description

Technical Field

[0001] This invention relates to the field of glass transfer equipment technology, and more particularly to a transfer device for glass processing. Background Technology

[0002] Flat glass, as a core material in construction, electronics, photovoltaics, and other fields, requires multiple processes in its processing, including cutting, edge grinding, and coating. The transfer between these processes is a crucial link affecting production efficiency and product qualification rate. Traditional glass transfer devices rely on vacuum pumps to maintain stable negative pressure. However, minor leaks in workshop pipelines and vacuum pump malfunctions can easily lead to fluctuations in negative pressure and a decrease in vacuum level. Under these conditions, the glass loses its effective adhesion and is prone to falling and breaking. Furthermore, the support platform and the glass are susceptible to adhesion due to atmospheric pressure or surface tension, especially in humid environments. Summary of the Invention

[0003] This invention provides a glass transfer device. The lower transfer bracket supports the glass panel from below, while glass wool provides double support from above and below, improving the stability of the glass panel during transfer and preventing the glass from falling and breaking due to changes in air pressure from the vacuum suction cup. This further reduces the probability of glass breakage during transfer. The glass is placed on top of the main plane frame and the main plane frame is pressed down. During the downward movement of the main plane frame, the middle piston contracts, generating suction on the glass and improving its stability, reducing the possibility of glass sliding. When the glass is lifted, the main plane frame moves upward, the middle piston expands and lifts the glass, facilitating smooth separation of the glass from the main plane frame during transfer. This solves the problem that the support platform and the glass are prone to adhesion due to atmospheric pressure or surface tension, requiring manual external force to peel them off during lifting, which reduces production efficiency.

[0004] This invention provides a glass processing transfer device, specifically including a main transfer frame, side transfer fixing frames, a main plane frame, and side extension support frames. Side transfer fixing frames are provided on both sides of the main transfer frame. Side extension support frames are slidably connected to the sides of the main plane frame. Vacuum suction cups are fixedly connected to the bottom of the main transfer frame in a cross-shaped array. The main transfer frame is an aluminum alloy frame structure. The vacuum suction cups are connected to a vacuum pump via PU tubing. The middle of the main transfer frame is bolted to a robotic arm. Upper telescopic cylinders are fixedly connected to both sides of the main transfer frame. Side telescopic frames are slidably connected to both sides of the main transfer frame. Positioning holes are arranged in a spaced array on the top of the side telescopic frames, and positioning pins are slidably connected to the inner sides of the positioning holes.

[0005] Furthermore, the upper end of the positioning pin and the telescopic rod of the upper telescopic cylinder are connected through the pin. The upper telescopic cylinder is fixedly connected to the side telescopic frame by sliding the positioning pin and the positioning hole.

[0006] Furthermore, both sides of the side transfer fixing frame are fixedly connected to side telescopic cylinders, and both sides of the side transfer fixing frame are vertically slidably connected to lower transfer brackets. The telescopic rods of the side telescopic cylinders are fixedly connected to the lower transfer brackets. An inner buffer pad is slidably connected to the lower side of the lower transfer bracket. A middle buffer spring is fixedly connected between the inner buffer pad and the lower transfer bracket. The inner buffer pad of the lower transfer bracket forms an elastic support from the bottom of the glass, and together with the middle buffer spring, it can absorb vertical vibration during the transfer process.

[0007] Furthermore, an inner buffer pad is slidably connected to the lower side of the side transfer bracket, and a middle buffer spring is fixedly connected between the inner buffer pad and the lower transfer bracket. The middle buffer spring is a stainless steel compression spring. The inner buffer pads of the side transfer bracket and the lower transfer bracket are arranged opposite to each other. The inner buffer pads of the side transfer bracket and the lower transfer bracket clamp and fix the glass in the middle from above and from below. When the vacuum system suddenly fails, the inner buffer pad of the lower transfer bracket supports and fixes the glass from below, and the glass will not fall directly.

[0008] Furthermore, airbag columns are fixedly installed in the grooves of the top spaced array of the main plane frame. The airbag columns are interconnected. A lower connecting slide column is fixedly connected to the bottom of the main plane frame. The lower connecting slide column and the lower support are slidably connected through each other. A lower support spring is fixedly connected between the lower support and the main plane frame. A lower telescopic cylinder is fixedly connected to the upper part of the lower support. A side piston is fixedly connected to the upper part of the lower support.

[0009] Furthermore, the top of the airbag column protrudes higher than the top surface of the main plane frame. The airbag column is made of silicone material, which can provide elastic cushioning when the glass is placed. The piston rod of the side piston is fixedly connected to the lower end of the lower connecting slide column, and the side piston and the airbag column pipeline are connected.

[0010] Furthermore, when the vacuum suction cup adsorbs the glass and lowers it above the main plane frame, the glass's gravity presses against the main plane frame, driving the lower connecting slide column to slide down along the lower support and compress the lower support spring. As the main plane frame moves down, the lower connecting slide column moves synchronously to stretch the side piston. The gas inside the airbag column flows into the side piston, causing the airbag column to elastically contract, reducing its protrusion height from 8mm to 2mm. This achieves soft contact placement of the glass, avoiding breakage due to rigid impact. While the airbag column elastically contracts, a local negative pressure is formed at the contact surface between the glass and the airbag column, firmly adsorbing the glass onto the main plane frame. When the glass is lifted up by the suction, the lower support spring resets and pushes the main plane frame upward. The side piston compresses, forcing the gas back into the airbag column, causing the airbag column to inflate again and generate an upward thrust, helping the glass to quickly separate from the main plane frame.

[0011] Furthermore, a central telescopic airbag is fixedly connected to the middle of the side extension support frame. The central telescopic airbag and the central piston pipeline are connected. The lower telescopic cylinder drives the central piston to stretch or compress, which can control the expansion or contraction of the central telescopic airbag. The central telescopic airbag drives the side extension support frame to slide along the side of the main plane frame.

[0012] Furthermore, the tail end of the telescopic airbag is fixedly connected to the side of the main plane frame, the piston rod of the middle piston is fixedly connected to the telescopic rod of the lower telescopic cylinder, and the middle piston is fixedly connected to the upper part of the lower support. When the lower telescopic cylinder extends, it pushes the middle piston to compress, forcing gas into the telescopic airbag. The airbag expands, driving the side extension support frame to expand outward to adapt to different widths of glass. When the lower telescopic cylinder retracts, the middle piston stretches and evacuates the air, the middle telescopic airbag retracts, and the side extension support frame returns to its original position. The middle telescopic airbag drives the side extension support frame to slide along the side of the main plane frame, expanding the support range of the side extension support frame and thus expanding the overall support width.

[0013] This invention provides a transfer device for glass processing, which has the following advantages: The vacuum suction cup adsorbs the glass from above, while the lower transfer bracket supports the glass panel from below. Glass wool provides double support from both above and below, improving the stability of the glass panel during transfer and preventing the glass from falling and breaking due to changes in air pressure from the vacuum suction cup, thus further reducing the probability of glass breakage during transfer.

[0014] The glass is placed on top of the main plane frame and the main plane frame is pressed down. During the process of the main plane frame lowering, the middle piston contracts and generates suction force on the glass, which improves the stability of the glass and reduces the possibility of the glass sliding. When the glass is lifted, the main plane frame moves upward, the middle piston expands and lifts the glass, which facilitates the smooth separation of the glass from the main plane frame during the transfer and solves the problem of adhesion between the support platform and the glass due to atmospheric pressure or surface tension.

[0015] The telescopic airbag moves synchronously with the side extension support frame, which expands the support range for the glass on top of the main plane frame, enabling compatibility with glass of different sizes and meeting the needs of glass processing workshops for multiple batches and specifications of transfer. The contact between the telescopic airbag and the glass also acts as a buffer, enhancing the stability of glass handling and providing effective protection for the glass edges and corners.

[0021] Example 1: Please refer to... Figures 1 to 8 : This invention proposes a glass processing transfer device, comprising a main transfer frame 1, side transfer fixing frames 2, a main plane frame 3, and a side extension support frame 4. Vacuum suction cups 101 are fixedly connected to the bottom of the main transfer frame 1 in a cross-shaped array. The main transfer frame 1 has an aluminum alloy frame structure. The vacuum suction cups 101 are connected to a vacuum pump via PU tubing. The middle of the main transfer frame 1 is bolted to a robotic arm. Upper telescopic cylinders 102 are fixedly connected to both sides of the main transfer frame 1. Side telescopic frames 103 are slidably connected to both sides of the main transfer frame 1. Positioning holes 104 are arranged in a spaced array on the top of the side telescopic frames 103, and positioning pins 105 are slidably inserted into the inner side of each positioning hole 104. The upper end of the positioning pin 105 is connected to the telescopic rod of the upper telescopic cylinder 102. The upper telescopic cylinder 102 is fixedly connected to the side telescopic frame 103 through the sliding insertion of the positioning pin 105 and the positioning hole 104. The telescopic rod of the upper telescopic cylinder 102 is fixedly connected to the side telescopic frame 103. Side telescopic frames 2 are provided on both sides of the main transfer frame 1. Side telescopic cylinders 201 are fixedly connected to both sides of the side telescopic frame 2. Lower transfer brackets 202 are vertically slidably connected to both sides of the side telescopic frame 2. The telescopic rod of the side telescopic cylinder 201 is fixedly connected to the lower transfer bracket 202. An inner buffer pad 203 is slidably connected to the lower side of the lower transfer bracket 202. The inner buffer pad 203 and the lower transfer bracket 202 are fixedly connected. A middle buffer spring 204 is fixedly connected to the inner buffer pad 203 of the lower transfer bracket 202, forming an elastic support from the bottom of the glass. Together with the middle buffer spring 204, it can absorb vertical vibrations during transfer. A side extension support frame 4 is slidably connected to the side of the main plane frame 3. Airbag columns 301 are fixedly installed in the grooves of the top of the main plane frame 3 at intervals, and the airbag columns 301 are interconnected. A lower connecting slide column 304 is fixedly connected to the bottom of the main plane frame 3, and the lower connecting slide column 304 and the lower bracket 302 are slidably connected through it. A lower support spring 305 is fixedly connected between the lower bracket 302 and the main plane frame 3. A lower telescopic cylinder 303 is fixedly connected to the upper part of the lower bracket 302. A side piston 306 is fixedly connected to the upper part of the lower support 302. The top of the airbag column 301 protrudes higher than the top surface of the main plane frame 3. The airbag column 301 is made of silicone material, which can provide elastic cushioning when the glass is placed. The piston rod of the side piston 306 is fixedly connected to the lower end of the lower connecting slide column 304. The side piston 306 and the airbag column 301 are connected by pipes. A middle telescopic airbag 401 is fixedly connected to the middle part of the side extension support frame 4. The middle telescopic airbag 401 and the middle piston 402 are connected by pipes. The lower telescopic cylinder 303 drives the middle piston 402 to compress or stretch, which can control the expansion or contraction of the middle telescopic airbag 401. The middle telescopic airbag 401 drives the side extension support frame 4 to slide along the side of the main plane frame 3.

[0022] In this embodiment, an inner buffer pad 203 is slidably connected to the lower side of the side transfer fixing frame 2. A middle buffer spring 204 is fixedly connected between the inner buffer pad 203 and the lower transfer bracket 202. The middle buffer spring 204 is a stainless steel compression spring. The inner buffer pad 203 of the side transfer fixing frame 2 and the inner buffer pad 203 of the lower transfer bracket 202 are arranged opposite to each other. The inner buffer pad 203 of the side transfer fixing frame 2 and the lower transfer bracket 202 clamp and fix the glass in the middle from above and from below. When the vacuum system suddenly fails, the inner buffer pad 203 of the lower transfer bracket 202 supports and fixes the glass from below, so that the glass will not fall directly, further reducing the glass breakage rate.

[0023] In this embodiment, when the vacuum suction cup 101 adsorbs the glass and lowers it above the main plane frame 3, the glass's gravity presses against the main plane frame 3, driving the lower connecting slide column 304 to slide down along the lower support 302 and compress the lower support spring 305. As the main plane frame 3 moves downward, the lower connecting slide column 304 moves synchronously to stretch the side piston 306. The gas inside the airbag column 301 flows into the side piston 306, causing the airbag column 301 to elastically contract, reducing its protrusion height from 8mm to 2mm. This achieves soft contact placement of the glass, avoiding breakage due to rigid impact. Simultaneously, the airbag column 301 elastically contracts... The contact surface between the glass and the airbag column 301 forms a local negative pressure, firmly adhering the glass to the main plane frame 3, preventing horizontal sliding during transportation. When the glass is lifted by adsorption, the lower support spring 305 resets and pushes the main plane frame 3 upward. The side piston 306 compresses and pushes the gas back to the airbag column 301, causing the airbag column 301 to inflate again, generating an upward thrust, which helps the glass to separate quickly from the main plane frame 3 without the need for additional external force intervention. This solves the problems of easy breakage of the corners due to hard contact during traditional glass transportation and placement, and difficulty in separation due to adsorption and adhesion during lifting.

[0024] In this embodiment, the tail end of the telescopic airbag 401 is fixedly connected to the side of the main plane frame 3, the piston rod of the middle piston 402 is fixedly connected to the telescopic rod of the lower telescopic cylinder 303, and the middle piston 402 is fixedly connected to the upper part of the lower support 302. When the lower telescopic cylinder 303 extends, it pushes the middle piston 402 to compress, forcing gas into the middle telescopic airbag 401. The expansion of the airbag drives the side extension support frame 4 to expand outward, adapting to glass of different widths. When the lower telescopic cylinder 303 retracts, the middle piston 402 stretches and evacuates the air, and the contraction of the middle telescopic airbag 401 drives the side extension support frame 4 to reset. The middle telescopic airbag 401 drives the side extension support frame 4 to slide along the side of the main plane frame 3, expanding the support range of the side extension support frame 4, thereby expanding the overall support width, adapting to flat glass of different sizes, improving the versatility of the equipment, and meeting the needs of glass processing workshops for multiple batches and specifications of transfer.

[0025] In this second embodiment, based on the first embodiment, pressure sensors are installed on both sides of the main transfer frame 1. The pressure sensors are connected to the pipeline of the vacuum suction cup 101. The pressure sensors monitor the negative pressure of the vacuum suction cup 101. When the vacuum pressure fluctuates and the suction is unstable, the side telescopic cylinder 201 automatically shortens. The side telescopic cylinder 201 drives the lower transfer bracket 202 to move further upward, further increasing the clamping force of the inner buffer pad 203 on the glass, improving the stability of the glass, and avoiding the situation where the pressure of the vacuum suction cup 101 is unstable and the glass is on the inner buffer pad 203. Under the support of the middle buffer spring 204, the inner buffer pad 203 and the glass sway back and forth. Especially during the movement, the unstable pressure of the vacuum suction cup 101 will aggravate the swaying of the glass, thus avoiding the situation where the glass sways and is damaged by collision.

[0026] The working principle of this invention: The vacuum suction cup 101 is made of nitrile rubber scratch-resistant material and has a cross-shaped array layout, which can form a uniformly distributed adsorption force field. This avoids glass stress breakage caused by excessive local pressure and prevents the suction cup material from scratching the glass surface. The inner buffer plate 203 of the lower transfer bracket 202 forms an elastic support from the bottom of the glass. Together with the middle buffer spring 204, it can absorb vertical vibration during the transfer process. When the vacuum system suddenly fails, the inner buffer plate 203 of the lower transfer bracket 202 supports and fixes the glass from below, so that the glass will not fall directly, reducing the glass breakage rate. This solves the safety hazards of single adsorption and the problem that the glass transfer device relies on air pressure stability for single vacuum adsorption, and the glass breaks easily when the air pressure fluctuates. When the glass is lowered to the top of the main plane frame 3, its gravity presses the main plane frame 3 downwards, simultaneously driving the lower connecting slide column 304 to stretch the side piston 306. This causes the gas inside the airbag column 301 to flow into the piston chamber. As the airbag column 301 elastically contracts, a local negative pressure is formed at the contact surface between the glass and the airbag column 301, firmly adhering the glass to the main plane frame 3 and preventing horizontal slippage during transport. This is suitable for transporting curved or thin glass. When the vacuum suction cup 101 lifts the glass upwards, the lower support spring... The component 305 pushes the main plane frame 3 to move upward synchronously, and the side piston 306 compresses the gas back to the airbag column 301. The airbag column 301 inflates and expands, restoring the 8mm protrusion height, generating an upward thrust, which helps the glass to separate from the main plane frame 3 quickly without the need for additional external force intervention. The separation time is shortened from 5-10 seconds to less than 1 second, and friction scratches on the glass surface are avoided during the separation process. This solves the problems of easy breakage of the corners due to hard contact during traditional glass transportation and placement, and difficulty in separation due to adsorption and adhesion during lifting. The lower telescopic cylinder 303 drives the middle piston 402 to compress or extend, controlling the expansion or contraction of the middle telescopic airbag 401. This, in turn, drives the side extension support frame 4 to slide along the side of the main plane frame 3, expanding the support range of the side extension support frame 4 and increasing the overall support width. This allows it to adapt to different sizes of flat glass, eliminating the need to disassemble or replace parts when changing sizes. Only the cylinder stroke needs to be adjusted, improving the equipment's versatility and meeting the multi-batch, multi-specification transfer needs of glass processing workshops. When the middle telescopic airbag 401 contacts the glass edge, it can generate elastic deformation, absorbing the lateral impact force during transfer, especially providing effective protection for easily broken glass corners, reducing the edge breakage rate. At the same time, the flexible contact of the airbag avoids the hard metal support from scratching the glass surface, further ensuring the surface quality of the glass after processing. This solves the problems of traditional transfer devices with fixed support ranges, only adapting to a single size of glass, requiring disassembly and adjustment when changing sizes, and the high breakage rate caused by hard contact support leading to glass edge collisions.
