Description

Technical Field

[0001] This application relates to the technical field of glass curtain wall panel processing equipment, specifically a glass curtain wall panel edge grinding anti-deviation clamp. Background Technology

[0002] Edge grinding of glass curtain wall panels is a key process to ensure their appearance quality and installation accuracy. During the processing, the panels need to be reliably positioned and fixed by clamps to avoid edge deviation or edge damage due to positional shift.

[0003] Currently, most existing clamps use a positioning method that clamps the edges of the glass curtain wall panel. This method achieves fixation through direct contact between the clamping components and the side of the panel, which can meet the stability requirements during processing to a certain extent. However, because the clamp needs to be fixed by clamping the edge, the clamping part occupies the area to be processed on the edge of the panel, making it impossible to directly perform edge grinding in this area. This problem directly results in discontinuous grinding and incomplete processing. Especially in scenarios requiring continuous edge grinding around the entire circumference, the un-grinded area of ​​the clamping part will form obvious processing breaks, which not only affects the overall aesthetics of the glass curtain wall panel but may also lead to the risk of breakage during subsequent use due to edge stress concentration.

[0004] Therefore, this application provides a glass curtain wall panel edge grinding anti-displacement clamp to solve the above problems. Utility Model Content

[0005] This application provides a glass curtain wall panel edge grinding anti-displacement fixture, which aims to solve the problems mentioned in the background art, such as grinding blind spots (grinding areas cannot be ground), discontinuous processing, and risk of breakage caused by edge stress concentration due to the use of side clamping in existing fixtures.

[0006] To achieve the above objectives, this application provides the following technical solution: a glass curtain wall panel edge grinding anti-displacement clamp, comprising a mounting base, an adsorption fixing unit disposed on the mounting base, and a center position correction mechanism;

[0007] The adsorption and fixing unit includes a vacuum suction cup assembly containing five suction cups with anti-slip textures on their adsorption surfaces. One suction cup is a central suction cup, and the other four are circumferential suction cups. The circumferential suction cups are symmetrically distributed in a square or rhombus shape with the central suction cup as the center. Each suction cup in the vacuum suction cup assembly is connected to an external vacuum generator through a vacuum tube. The symmetrical layout of the central and circumferential suction cups achieves uniform adsorption and fixing of the glass curtain wall panel surface, avoiding the grinding blind spots caused by traditional edge clamping, and eliminating the risk of glass deformation or displacement caused by local stress concentration, thus ensuring the stability and processing accuracy of the edge grinding process.

[0008] The center position correction mechanism includes two sets of opposing clamping plate assemblies. Each clamping plate assembly includes two clamping plates symmetrically arranged along the adsorption and fixing unit, and a driving component for driving the clamping plates to move towards the edge of the glass curtain wall panel and correct its center position. By synchronously and symmetrically moving the two sets of opposing clamping plate assemblies, automated center positioning of the glass curtain wall panel is achieved, avoiding manual centering errors and significantly improving positioning accuracy. Combined with the non-edge adsorption method of the adsorption and fixing unit, precise positioning can be completed without obstructing the processing area at the glass edge, providing a fundamental guarantee for subsequent continuous edge grinding around the entire circumference.

[0009] Preferably, a pressure sensor is installed on the vacuum tube. This sensor monitors the vacuum level of the vacuum suction cup assembly in real time, preventing suction failure due to vacuum system leaks or insufficient pressure. It provides real-time data feedback for the stable clamping of the glass curtain wall panel, improving the safety and reliability of the processing. The pressure sensor is integrated inside the vacuum tube, continuously collecting pressure values ​​in the vacuum circuit and transmitting the data to the control system. When the vacuum level falls below a preset threshold, the system automatically alarms or triggers an emergency shutdown, ensuring that the suction force always meets the processing requirements.

[0010] Preferably, to avoid scratching the glass during adsorption: the suction cup body of the vacuum suction cup assembly is made of silicone or nitrile rubber material with Shore hardness. Using silicone or nitrile rubber material with Shore hardness gives the suction cup good elastic deformation capability and wear resistance, allowing it to closely conform to the curved or slightly uneven surface of the glass curtain wall panel while avoiding glass scratches caused by rigid contact, and extending the service life of the suction cup.

[0011] Preferably, to avoid scratching the glass during calibration: an elastic buffer layer is provided on the inner surface of the clamping plate. The elastic buffer layer is a rubber pad with anti-slip texture on its surface. Through the flexible contact of the elastic buffer layer, the rigid impact of the clamping plate on the edge of the glass curtain wall panel during the center position calibration is eliminated, avoiding edge scratches or damage caused by mechanical stress during calibration. At the same time, the anti-slip texture design enhances the friction between the clamping plate and the edge of the glass, improving the stability of the calibration process.

[0012] Preferably, the mounting base has a guide groove for the lateral movement of the clamping plate. This provides precise guidance for the lateral movement of the clamping plate, restricts its degree of freedom of movement, ensures that the clamping plate moves along a preset straight trajectory, avoids center position correction errors caused by shaking or offset, and improves the motion accuracy and stability of the positioning mechanism.

[0013] Preferably, the driving component includes a bidirectional lead screw rotatably inserted into the mounting base, two clamping plates symmetrically threaded onto the bidirectional lead screw, and a drive motor fixedly mounted on the mounting base. The output shaft of the drive motor is fixedly connected to one end of the bidirectional lead screw. Through the cooperation of the bidirectional lead screw and the drive motor, the two sets of clamping plates move synchronously and symmetrically, automatically pushing the glass curtain wall panel to the center position of the mounting base, replacing manual centering operations, improving positioning efficiency and accuracy, and avoiding human error.

[0014] Preferably, to facilitate operator control of the adsorption fixing unit and the center position correction mechanism, the system further includes a controller fixedly mounted on the mounting base and electrically connected to the drive motor and vacuum generator, and an operation panel mounted on the controller. The operation panel is electrically connected to the controller, and its surface is equipped with multiple control buttons and a display screen. Through the integrated control module and visual operation interface, intelligent control of components such as the drive motor and vacuum generator is achieved, allowing operators to monitor equipment status in real time, input processing parameters, improve equipment usability and automation, and reduce the difficulty of manual operation.

[0015] This application achieves uniform adsorption and fixation of the glass curtain wall panel surface through a symmetrical layout of a central suction cup and circumferential suction cups, avoiding the grinding blind spots caused by traditional side clamping, while eliminating the risk of glass deformation or displacement caused by local stress concentration, and ensuring the stability and processing accuracy of the edge grinding process.

[0016] This application achieves automated center positioning of the glass curtain wall panel by synchronously and symmetrically moving two sets of opposing clamping plate components, avoiding manual centering errors and significantly improving positioning accuracy. Combined with the non-edge adsorption method of the adsorption fixing unit, it can complete precise positioning without obstructing the processing area of ​​the glass edge, providing a basic guarantee for subsequent continuous edge grinding around the entire circumference.

[0017] This application achieves intelligent control of components such as drive motors and vacuum generators through an integrated control module and a visual operation interface, making it convenient for operators to monitor equipment status in real time, input processing parameters, improve the ease of use and automation of the equipment, and reduce the difficulty of manual operation.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] This embodiment provides a glass curtain wall panel edge grinding anti-displacement clamp, such as Figure 1-2 As shown, the fixture includes a mounting base 1, an adsorption and fixing unit 2 disposed on the mounting base 1, and a center position correction mechanism 3; wherein, the mounting base 1 is provided with mounting holes for fixing the mounting base 1 to the desired position on the worktable of the grinding equipment by bolts.

[0024] The adsorption and fixing unit 2 includes a vacuum suction cup group 21, which contains five suction cups with anti-slip textures on their adsorption surfaces. One of them is a central suction cup 211, and the other four are circumferential suction cups 212. The circumferential suction cups 212 are symmetrically distributed in a square or rhombus shape with the central suction cup 211 as the center. Each suction cup of the vacuum suction cup group 21 is connected to an external vacuum generator through a vacuum tube 213. Through the symmetrical layout of the central suction cup 211 and the circumferential suction cups 212, uniform adsorption and fixing of the glass curtain wall panel surface is achieved, avoiding the grinding blind spots caused by traditional edge clamping, and eliminating the risk of glass deformation or displacement caused by local stress concentration, thus ensuring the stability and processing accuracy of the edge grinding process. An external vacuum generator provides vacuum suction to the central suction cup 211 and four circumferential suction cups 212 simultaneously through a vacuum tube 213. The five suction cups are distributed in a centrally symmetrical manner (square / rhombus) in the non-edge area of ​​the glass curtain wall panel. The anti-slip texture on the adsorption surface increases the friction of the contact surface, so that the adsorption force is evenly applied to the glass surface, achieving reliable fixation without contacting the edge processing area.

[0025] The center position correction mechanism 3 includes two sets of opposing clamping plate assemblies 31. Each set of clamping plate assemblies 31 includes two clamping plates 311 symmetrically arranged along the adsorption and fixing unit 2 and a driving component 312 for driving the clamping plates 311 to move towards the edge of the glass curtain wall panel and correct its center position. By synchronously and symmetrically moving the two sets of opposing clamping plate assemblies 31, automated center positioning of the glass curtain wall panel is achieved, avoiding manual centering errors and significantly improving positioning accuracy. Combined with the non-edge adsorption method of the adsorption and fixing unit 2, accurate positioning can be completed without obstructing the processing area of ​​the glass edge, providing a basic guarantee for subsequent continuous edge grinding around the entire circumference. After the driving component 312 is activated, it drives the two clamping plates 311 symmetrically arranged along the adsorption and fixing unit 2 to move towards the edge of the glass curtain wall panel. The two sets of clamping plates 311 form a resultant force through symmetrical thrust, gradually pushing the glass curtain wall panel to the geometric center position of the mounting base 1. Because the clamping plate 311 moves synchronously along a preset symmetrical direction, it ensures that the glass is subjected to uniform force during translation, avoiding skewing or offset caused by force on one side, and ultimately achieving high-precision automatic mechanical centering. After the alignment is completed, the glass curtain wall panel is adsorbed and fixed by the adsorption and fixing unit 2, and then the clamping plate 311 is moved away from the glass curtain wall panel by the driving component 312, and then the edge grinding operation of the glass curtain wall panel can be performed.

[0026] A pressure sensor 214 is installed on the vacuum tube 213. A pressure sensor 24 (model MPX5010DP) monitors the vacuum level of the vacuum suction cup assembly 21 in real time, preventing suction failure due to vacuum system leaks or insufficient pressure. This provides real-time data feedback for stable clamping of the glass curtain wall panel, improving the safety and reliability of the processing. The pressure sensor 214 is integrated inside the vacuum tube 213, continuously collecting pressure values ​​in the vacuum circuit and transmitting the data to the control system. When the vacuum level falls below a preset threshold, the system automatically alarms or triggers an emergency shutdown, ensuring that the suction force always meets processing requirements.

[0027] To avoid scratching the glass during adsorption, the suction cup body of vacuum suction cup assembly 21 is made of silicone or nitrile rubber with Shore hardness. Using silicone or nitrile rubber with Shore hardness gives the suction cup excellent elastic deformation capability and wear resistance, allowing it to closely conform to the curved or slightly uneven surfaces of the glass curtain wall panel while avoiding scratches caused by rigid contact, thus extending the suction cup's service life. The elastic material of the suction cup body can adapt to the contours of the glass surface during vacuum adsorption, filling tiny gaps through deformation to enhance the sealing effect; the choice of Shore hardness balances elasticity and support force, and the anti-slip texture further increases the coefficient of friction of the contact surface, achieving a balance between flexible contact and rigid fixation during adsorption.

[0028] To prevent scratches on the glass during alignment, an elastic buffer layer 3111 is provided on the inner surface of the clamping plate 311. The elastic buffer layer 3111 is a rubber pad with anti-slip textures on its surface. Through the flexible contact of the elastic buffer layer 3111, the rigid impact of the clamping plate 311 on the edge of the glass curtain wall panel during center position alignment is eliminated, preventing edge scratches or damage caused by mechanical stress during alignment. Simultaneously, the anti-slip texture design enhances the friction between the clamping plate and the glass edge, improving the stability of the alignment process. When the clamping plate 311 moves towards the glass edge under the action of the driving component 312, the rubber pad first contacts the glass edge, absorbing the impact energy through its own elasticity and reducing the impact force at the moment of contact. The surface anti-slip texture increases the static friction between the clamping plate and the glass edge, allowing the glass to move synchronously with the clamping plate during translation, preventing slippage and misalignment.

[0029] The mounting base 1 has a guide groove 11 for the lateral movement of the clamping plate 311. This provides precise guidance for the lateral movement of the clamping plate 311, restricts its degree of freedom of movement, ensures that the clamping plate 311 moves along a preset straight trajectory, avoids center position correction errors caused by shaking or offset, and improves the motion accuracy and stability of the positioning mechanism. When the driving component 312 moves the clamping plate 311, the groove wall of the guide groove 11 constrains the movement direction of the clamping plate, ensuring that the clamping plate can only move in a straight line along the lateral direction of the mounting base 1 (i.e., the center correction direction of the glass curtain wall panel), eliminating lateral displacement deviation.

[0030] The driving component 312 includes a bidirectional lead screw 3121 rotatably inserted into the mounting base 1. Two clamping plates 311 are symmetrically threaded onto the bidirectional lead screw 3121. A drive motor 3122 is fixedly mounted on the mounting base 1, and the output shaft of the drive motor 3122 is fixedly connected to one end of the bidirectional lead screw 3121. Through the cooperation of the bidirectional lead screw 3121 and the drive motor 3122, the two sets of clamping plates 311 move synchronously and symmetrically, automatically pushing the glass curtain wall panel to the center position of the mounting base 1, replacing manual centering operation, improving positioning efficiency and accuracy, and avoiding human error. After the drive motor 3122 is powered on, it drives the bidirectional lead screw 3121 to rotate. The positive and negative threads at both ends of the lead screw engage with the nut seats of the two clamping plates 311, causing the two clamping plates 311 to move synchronously in opposite directions under the constraint of the guide groove 11. When the clamping plate 311 contacts the edge of the glass, the continuous symmetrical thrust automatically adjusts the glass to the center position of the lead screw, i.e., the geometric center of the mounting base 1, achieving high-precision mechanical alignment. After the alignment is completed, the glass curtain wall panel is adsorbed and fixed by the adsorption fixing unit 2. Then, the reverse rotation of the drive motor 3122 moves the clamping plate 311 away from the glass curtain wall panel, allowing the edge grinding operation to be performed on the glass curtain wall panel. The drive motor 3122 is a servo motor (model MR-J4-40A).

[0031] To facilitate operator control of the adsorption fixing unit 2 and the center position correction mechanism 3, the system also includes a controller 4 fixedly mounted on the mounting base 1 and electrically connected to the drive motor 3122 and the vacuum generator, and an operation panel 41 mounted on the controller 4. The operation panel 41 is electrically connected to the controller 4 and has multiple control buttons and a display screen on its surface. Through the integrated control module and visual operation interface, intelligent control of components such as the drive motor 3122 and the vacuum generator is achieved, allowing operators to monitor equipment status and input processing parameters in real time, improving equipment usability and automation, and reducing the difficulty of manual operation. The controller 4 uses a PLC controller (model FX5U-32MT / ES). As the core control unit of the equipment, the controller 4 receives button commands from the operation panel 41 (such as "start centering" and "start vacuum adsorption") and sends control signals to the drive motor 3122, vacuum generator, and other actuators according to preset programs or sensor feedback. The display screen on the operation panel 41 displays the equipment operating parameters in real time, forming a closed-loop human-machine interaction and realizing full-process digital control.

[0032] The wiring diagram of the drive motor 3122 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the drive motor 3122 will not be explained in detail.

[0033] The control method of this application is controlled by controller 4. The control circuit of controller 4 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0034] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0035] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
