Description

Technical Field

[0001] This utility model relates to the field of glass handling, and in particular to a device for preventing scratches during the handling of tempered glass. Background Technology

[0002] In traditional tempered glass handling operations, manual handling was initially the primary method. Operators used simple tools such as suction cups and crowbars, with multiple people working together to load, unload, and transfer the glass. To improve the drawbacks of manual handling, some simple handling equipment began to appear in the industry, such as manual hydraulic forklifts with glass fixing racks and small cranes.

[0003] With the development of automation technology, some companies have begun to introduce automated handling equipment, such as robotic arms paired with vacuum suction cup mechanisms. These devices improve the automation and precision of handling to a certain extent, enabling actions such as gripping, lifting, rotating, and translating glass.

[0004] Existing handling equipment mostly uses rigid clamping and single adsorption methods, lacking effective flexible pressure control functions. When the glass is placed or shakes during handling, stress concentration causes fine scratches or hidden damage to the glass surface. It is difficult to simultaneously ensure handling stability and surface protection. At the same time, existing handling equipment generates low-frequency vibrations and instantaneous impacts during movement, especially during start-up, braking, or when passing over uneven ground. These dynamic loads are transmitted to the glass body through rigidly connected clamping or adsorption components. This may not only cause slight relative displacement between the glass and the clamping point, resulting in surface scratches, but more seriously, it may generate alternating stress inside the glass. Therefore, a tempered glass handling anti-scratch device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tempered glass handling and anti-scratch device, which aims to improve the problem that the lack of flexible clamping in existing tempered glass handling and anti-scratch devices increases the risk of scratches.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tempered glass handling and anti-scratch device, comprising a bracket, a movable component mounted on the bracket, a mounting plate mounted on the movable component, a cylinder fixedly connected to the mounting plate, a drive plate fixedly connected to the output end of the cylinder, the drive plate being slidably connected to a slide rail on the mounting plate via a slide block, a support rod fixedly connected to both the slide block and the mounting plate, a fixed plate fixedly connected to the bottom end of the support rod, a motor fixedly connected to the top of the fixed plate, a lead screw fixedly connected to the output end of the motor, a movable seat threadedly connected to the outer wall of the lead screw via a nut, an electric push rod fixedly connected to the movable seat, an adjusting frame fixedly connected to the output end of the electric push rod, a double-headed electric push rod fixedly connected to the outer wall of the adjusting frame, clamps fixedly connected to both ends of the double-headed electric push rod, an air pump fixedly connected to the clamps, an air bladder fixedly connected to the port of the air pump via an air pipe, an air bladder fixedly connected to the adjusting frame, and an adsorption component mounted on the fixed plate.

[0007] As a further description of the above technical solution:

[0008] The clamp and the side of the airbag away from the adjustment frame are chamfered.

[0009] As a further description of the above technical solution:

[0010] The airbag has a shallow groove, and a pressure sensor is fixedly connected in the shallow groove.

[0011] As a further description of the above technical solution:

[0012] The adsorption assembly includes a vacuum pump, which is fixed on a fixed plate. The output end of the vacuum pump is fixedly connected to a pipe, and the bottom end of the pipe is fixedly connected to a vacuum suction cup.

[0013] As a further description of the above technical solution:

[0014] Each set of fixed plates is equipped with four sets of vacuum pumps arranged in a rectangular array, and the number of pipes and vacuum suction cups is the same as the number of vacuum pumps.

[0015] As a further description of the above technical solution:

[0016] A gas collecting ring is fixedly connected to the pipeline. Several sets of arc-shaped bends are fixedly connected to the inner wall of the gas collecting ring. An air injection pipeline is fixedly connected to the inner wall of the gas collecting ring. A distributor and a regulating valve are fixedly connected to the air injection pipeline respectively.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, flexible clamping and precise pressure control are achieved by setting an airbag and a pressure sensor. Combined with the non-Newtonian fluid airbag for shock absorption and buffering, scratches on the glass surface are effectively avoided. At the same time, the vacuum adsorption component is used to enhance the fixation stability, and the multi-directional adjustment mechanism is combined to achieve smooth handling, thereby improving the safety and protection effect of tempered glass handling operations.

[0023] 2. In this utility model, the exhaust gas from the vacuum pump is guided to the glass surface through the gas collecting ring and the multi-directional arc-shaped bend, forming an airflow that blows from the suction cup area to both sides, effectively removing dust from the contact surface. This not only prevents dust from affecting the sealing and stability of vacuum adsorption, but also prevents particles from scratching the glass surface during handling, improving the cleanliness of the operation and the protective effect of the glass.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3The present invention provides an embodiment of a tempered glass handling and scratch-proof device, comprising a support 1, on which a movable component 2 is mounted. The movable component 2 is a conventional moving mechanism in the art, such as a trolley chassis including a drive motor, reducer, wheels and steering mechanism, or an electric trolley mounted on an overhead track. Its specific implementation is a conventional choice by those skilled in the art based on the actual application scenario, enabling translational movement of the support 1 and all its components in space. A mounting plate 3 is mounted on the movable component 2, and a cylinder 4 is fixedly connected to the mounting plate 3. The output end of the cylinder 4 is fixedly connected to a drive plate 5, and the drive plate 5 is connected to a slide rail 6 on the mounting plate 3 via a slide seat 7. The sliding connection includes a support rod 8 fixedly connected to both the slide block 7 and the mounting plate 3. A fixing plate 9 is fixedly connected to the bottom end of the support rod 8, and a motor 10 is fixedly connected to the top of the fixing plate 9. A lead screw 11 is fixedly connected to the output end of the motor 10. A movable seat 15 is threadedly connected to the outer wall of the lead screw 11 via a nut. An electric push rod 16 is fixedly connected to the movable seat 15, and an adjusting frame 17 is fixedly connected to the output end of the electric push rod 16. Two sets of equally spaced slide rods are fixedly installed on each adjusting frame 17. The two sets of slide rods are staggered in height and pass through the movable seat 15, providing support and guidance when the adjusting frame 17 moves. A double-headed electric push rod 18 is fixedly connected to the outer wall of the adjusting frame 17. Both ends of component 8 are fixedly connected to clamping plates 19. Each set of adjusting frames 17 has two sets of slots at equal intervals, which allow the clamping plates 19 to slide and limit their movement. An air pump 20 is fixedly connected to the clamping plates 19 to provide air for the inflation and deflation of the airbag 21. The inflation degree of the airbag 21 can be adjusted as needed. The port of the air pump 20 is fixedly connected to the airbag 21 through an air pipe, making flexible contact with the glass to avoid scratching the glass surface due to rigid clamping and to enhance the fit of the clamping. The clamping plates 19 and the side of the airbag 21 away from the adjusting frame 17 are chamfered to prevent the edges of the components from bumping or scratching the glass surface when approaching or contacting the glass. A flexible bladder body 22 is fixedly connected to the adjusting frame 17. A sealed container made of materials such as rubber or silicone is fixed in the groove of the adjusting frame 17 by means of clamps, adhesives, or vulcanization. The bladder 22 is filled with a non-Newtonian fluid, preferably a shear-thickening fluid, such as a mixture of polyethylene glycol and silica nanoparticles. When the equipment is running smoothly and subjected to slow shearing, the fluid is in a liquid state. The bladder 22 is soft and does not affect the normal adjustment of the clamping mechanism. When the handling process encounters severe vibration or impact, the stress rate acting on the bladder 22 increases sharply, and the shear-thickening fluid inside instantly turns into a near-solid state, and the modulus increases sharply, thereby dissipating and absorbing a large amount of impact energy and reducing the dynamic load transmitted to the glass being clamped through the adjusting frame 17.

[0034] Reference Figures 4-6The airbag 21 has a shallow groove 23 to provide installation space for the pressure sensor 24, ensuring that the sensor position is fixed and does not affect the normal expansion of the airbag 21. The pressure sensor 24 is fixedly connected in the shallow groove 23 to monitor the pressure value when the airbag 21 contacts the glass in real time, providing data for adjusting the clamping pressure. Each pair of airbags 21 has a shallow groove 23 on one side opposite each other, and a pressure sensor 24 is installed in each shallow groove 23 to ensure that each clamping structure can accurately monitor the pressure and avoid excessive or insufficient local pressure that could damage or cause the glass to fall off. The fixing plate 9 is equipped with an adsorption component, which uses negative pressure adsorption. The glass is initially fixed to enhance stability during handling. The adsorption assembly includes a vacuum pump 12, a pipe 13, and a vacuum suction cup 14. Four sets of vacuum pumps 12 arranged in a rectangular array are fixedly installed on the fixing plate 9. The vacuum pumps 12 are fixedly connected to the output end of the vacuum pump 12 via the pipe 13. The bottom end of the pipe 13 is fixedly connected to the vacuum suction cup 14. The vacuum pump 12 is a conventional vacuum generating device with an air intake port and an air exhaust port. The pipe 13 is connected to the air intake port of the vacuum pump 12 to provide negative pressure to the vacuum suction cup 14.

[0035] Reference Figures 4-6A gas collecting ring 25 is fixedly connected to the pipe 13. Several sets of arc-shaped bends 26 are fixedly connected to the inner wall of the gas collecting ring 25. Through a specific orientation design, the airflow direction is guided to achieve directional blowing of dust from the glass surface. The orientation of the arc-shaped bends 26 on each set of gas collecting rings 25 is different, allowing for dust removal of different areas of the glass, ensuring no dead corners in dust removal. The openings of the arc-shaped bends 26 on the four sets of gas collecting rings 25 closest to the support 1 face the support 1, causing the airflow on that side to blow towards the support 1, guiding the dust away from the suction port of the vacuum suction cup 14. The openings of the arc-shaped bends 26 on the four sets of gas collecting rings 25 away from the support 1 face away from the support 1, causing the airflow on that side to blow away from the support 1, coordinating with the airflow on the other side. This ensures that when the gas blows across the glass surface, dust is blown away from the suction port of the vacuum suction cup 14 to both sides, preventing dust residue. To prevent dust from scratching the glass surface and affecting the adsorption effect, the inner wall of the gas collecting ring 25 is fixedly connected to an injection pipe 27, which serves as a gas delivery channel to transfer the gas supplied by the vacuum pump 12 to the gas collecting ring 25. The outer wall of the injection pipe 27 is fixedly connected to the inner wall of the fixing plate 9, and the end of the injection pipe 27 away from the gas collecting ring 25 is fixedly connected to the vacuum pump 12. A distributor 28 and a regulating valve 29 are fixedly connected to the injection pipe 27. The injection pipe 27 is connected to the exhaust port of the vacuum pump 12. When the vacuum pump 12 is working, the high-pressure gas discharged by it is delivered to the gas collecting ring 25 through the injection pipe 27. The airflow can be controlled by the regulating valve 29 set on the injection pipe 27. Finally, the airflow is blown towards the glass surface in a specific direction through multiple sets of arc-shaped bends 26 on the gas collecting ring 25, completing the cleaning before the vacuum suction cup 14 adsorbs it.

[0036] Working principle: First, the moving component 2 moves the mounting plate 3 to the corresponding position of the tempered glass to be transported. The cylinder 4 is activated, and under the driving force of the cylinder 4, the driving plate 5 slides stably along the slide rail 6, thereby driving the corresponding support rod 8 to move synchronously, so that the fixing plate 9 is close to the tempered glass. During the movement of the fixing plate 9, the adsorption component on it is activated. The vacuum pump 12 also delivers gas to the gas collecting ring 25 through the gas injection pipe 27. The distributor 28 on the gas injection pipe 27 can evenly distribute the gas to each gas collecting ring 25. The regulating valve 29 can regulate the gas delivery pressure. After the gas enters the gas collecting ring 25, it passes through several layers of the inner wall. The vacuum pumps 12, arranged in a rectangular array, spray air from different curved pipes 26, creating a lateral airflow that blows dust from the tempered glass surface away from the suction port of the vacuum cup 14. This prevents dust from getting trapped between the suction cup and the glass, affecting the adsorption stability, and also prevents dust from scratching the glass surface during handling. The four vacuum pumps 12, arranged in a rectangular array, are activated, drawing air out of the vacuum cups 14 through pipes 13. This creates negative pressure in the vacuum cups 14, causing them to adhere tightly to the tempered glass surface, thus initially positioning and pre-fixing the glass. Subsequently, the motor 10 is activated, converting the rotational motion of the lead screw 11 into the linear motion of the moving base 15. The linear motion adjusts the movable seat 15 to a position suitable for the glass size. The electric push rod 16 on the movable seat 15 is activated, pushing the adjusting frame 17 closer to the tempered glass. The double-headed electric push rod 18 is then activated until the two sets of clamping plates 19 are in contact with both sides of the glass. At this point, the air pump 20 on the clamping plates 19 is activated, inflating the airbag 21 through the air tube. After inflating, the airbag 21 tightly adheres to the glass surface, achieving flexible clamping of the glass and avoiding scratches caused by rigid contact. Simultaneously, the pressure sensor 24 within the shallow groove 23 of the airbag 21 monitors the clamping pressure in real time, ensuring the pressure is within a suitable range to prevent damage to the glass from excessive pressure or damage from insufficient pressure. This can cause the glass to fall off. In addition, the non-Newtonian fluid stored inside the bladder 22 on the adjusting frame 17 can absorb the impact force when the equipment vibrates or is subjected to external impact, further improving the stability of the glass during the handling process and preventing the glass from being scratched by friction with the equipment parts due to vibration. After the glass is adsorbed and clamped, the moving component 2 is restarted, driving the entire clamping structure and the glass to the target position. After reaching the target position, the double-headed electric push rod 18, air pump 20, and vacuum pump 12 are turned off in sequence to release the clamping and adsorption of the glass, completing a scratch-proof handling operation of tempered glass.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
