Description

Technical Field

[0001] This utility model relates to the field of glass inspection technology, and in particular to a glass inspection fixture centering positioning device and a glass inspection fixture. Background Technology

[0002] In the production and inspection of deeply curved automotive glass, the accuracy of the fixture's centering position directly determines the reliability of the inspection results. Currently, the centering position of glass fixtures mainly relies on two methods: manual centering or cylinder centering.

[0003] Manual centering positioning relies entirely on the operator's experience for adjustment. During the positioning process, it is difficult to control the force applied to the glass, which can easily lead to uneven stress and deformation of the glass. This, in turn, affects the centering and fit dimensions of the inspection tool, resulting in inspection distortion. Cylinder centering positioning achieves positioning through air pressure drive, but the air pressure control precision is limited and cannot accurately match the stress requirements of different glasses. It also carries the risk of glass deformation and has poor positioning repeatability.

[0004] Therefore, there is an urgent need to provide a glass fixture centering and positioning device to solve the problems of low centering and positioning accuracy of glass fixtures, easy glass deformation, and low centering and positioning accuracy in the existing technology. Utility Model Content

[0005] In view of the above, this application provides a glass fixture centering and positioning device and a glass fixture to solve at least one of the problems mentioned in the background art.

[0006] This application provides a glass fixture centering and positioning device, including: The system includes a positioning assembly, a guide rail, an electric cylinder, a sensor, and a locking component. The positioning assembly is used to position the main body of the fixture and the glass disposed on the main body of the fixture. The positioning component is disposed on the guide rail, the electric cylinder is connected to the positioning component to drive the positioning component to move along the guide rail, and the locking member is connected to the positioning component and the guide rail respectively to unlock or lock the movement of the positioning component relative to the guide rail; The sensor is located on the electric cylinder and is used to detect the force applied by the positioning component to the fixture body.

[0007] In one alternative embodiment, the positioning component includes a connecting seat and a positioning wheel. The connecting seat has a positioning end for abutting against the main body of the inspection fixture, and the positioning wheel is used to position the glass. The positioning wheel moves synchronously with the connecting seat.

[0008] In an optional embodiment, the glass fixture centering and positioning device further includes a floating joint, and the connecting seat is connected to the electric cylinder through the floating joint.

[0009] In an optional embodiment, the glass fixture centering and positioning device further includes a controller, which is connected to the electric cylinder and the sensor respectively. The controller can control the force output by the electric cylinder according to the detection result of the sensor.

[0010] In an optional embodiment, the positioning component further includes a fixing block, and the positioning wheel is connected to the connecting seat through the fixing block and is located above the connecting seat.

[0011] In one alternative embodiment, the positioning wheel is rotatably disposed on the fixed block, and the rotation axis of the positioning wheel is parallel to the vertical direction.

[0012] In one alternative embodiment, the locking element includes a clamp that moves synchronously with the connector.

[0013] In one alternative embodiment, the extension direction of the guide rail is parallel to the axial direction of the electric cylinder.

[0014] In one alternative embodiment, the sensor is integrated into the electric cylinder.

[0015] This utility model also provides a glass inspection fixture, which includes the glass inspection fixture centering and positioning device described in any of the preceding claims.

[0016] The glass fixture centering and positioning device provided in this application embodiment uses a guide rail and an electric cylinder to drive the positioning component to move, positioning the component with the fixture body and the glass respectively, thus performing a positioning action. After the device is activated, the locking element is unlocked, allowing the electric cylinder to drive the positioning component to move along the guide rail towards the fixture body. The guide rail guides the positioning component's movement, improving the stability of the positioning component's movement. When the positioning component abuts against the fixture body, and the sensor detects that the force between the positioning component and the fixture body reaches a preset threshold, the electric cylinder stops, and the locking element switches to the locked state. The positioning component cannot move relative to the guide rail, ensuring the glass remains stably centered. Therefore, the glass fixture centering and positioning device provided in this application embodiment significantly improves the accuracy of fixture centering and positioning, increasing the repeatability accuracy to ±0.1mm, effectively solving the problem of inaccuracy in traditional positioning methods, ensuring the reliability of glass inspection results, and meeting high-precision inspection requirements.

[0021] To make the technical solution and beneficial effects of this utility model more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0022] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0023] An embodiment of this utility model provides a glass fixture centering and positioning device 1000, such as... Figure 1 and Figure 2As shown, it includes: a positioning component 100, a guide rail 200, an electric cylinder 300, a sensor 400, and a locking member 500. The positioning component 100 is used to position the fixture body 2000 and the glass 3000 disposed on the fixture body. The positioning component 100 is disposed on the guide rail 200. The electric cylinder 300 is connected to the positioning component 100 to drive the positioning component 100 to move along the guide rail 200. The locking member 500 is connected to the positioning component 100 and the guide rail 200 to unlock or lock the movement of the positioning component 100 relative to the guide rail 200. The sensor 400 is disposed on the electric cylinder 300 and is used to detect the force applied by the positioning component 100 to the fixture body 2000.

[0024] Before using a fixture to center the glass, it is necessary to ensure accurate positioning between the glass and the fixture body. In the glass fixture centering and positioning device 1000 provided in this embodiment, a guide rail 200 and an electric cylinder 300 are used to drive the positioning component 100 to move, positioning the positioning component 100 with the fixture body 2000 and the glass 3000 respectively, thus performing the positioning action. After the device is activated, the locking member 500 is in the unlocked state, allowing the electric cylinder 300 to drive the positioning component 100 to move along the guide rail 200 towards the fixture body 2000. The guide rail 200 guides the movement of the positioning component 100, improving the stability of the movement process. When the positioning component 100 abuts against the fixture body 2000, and the sensor 400 detects that the force between the positioning component 100 and the fixture body 2000 reaches a preset threshold, the electric cylinder 300 stops moving, and the locking member 500 switches to the locked state. The positioning component 100 cannot move relative to the guide rail 200, ensuring that the glass 3000 is stably centered.

[0025] Therefore, the glass fixture centering and positioning device 1000 provided in this application embodiment can connect the electric cylinder 200, guide rail 300, and locking component 500 together, improving the instability caused by multiple positioning actions and reducing the risk of high-precision product distortion. Combined with the force detection during positioning by the sensor 400, it can reduce the risk of glass 3000 deformation during positioning and improve the accuracy of fixture centering. Furthermore, this device can improve the repeatability accuracy of fixture 2000 centering during use. In a preferred embodiment, using the glass fixture centering and positioning device 1000 provided in this application embodiment can improve the repeatability accuracy of detection to ±0.1mm, effectively solving the problem of inaccuracy in traditional positioning methods, ensuring the reliability of glass inspection results, and meeting the requirements of high-precision inspection.

[0026] For example, the preset threshold is set according to the performance parameters of the glass 3000 (such as material, thickness, curvature), and can be set to any value from 1 to 200N according to the actual situation of the glass 3000 to be tested.

[0027] In this embodiment, the electric cylinder 300 includes a piston rod 310, a cylinder body 320, and a motor (not shown in the figure). By replacing the traditional manual or pneumatic cylinder drive with the electric cylinder 300 drive, and with the force detection of the sensor 400 and the precise fixation of the locking member 500, the repeatability accuracy of the detection can be improved to ±0.1mm.

[0028] In an alternative embodiment, such as Figure 1 As shown, the positioning assembly 100 includes a connecting seat 110 and a positioning wheel 120. The connecting seat 110 has a positioning end 111 for abutting against the fixture body 2000, and the positioning wheel 120 is used to position the glass. The positioning wheel 120 moves synchronously with the connecting seat 110. In this embodiment, the connecting seat 110 provides a mounting carrier for the positioning wheel 120. When the positioning wheel 120 moves with the connecting seat 110, it contacts the glass 3000. The rolling of the positioning wheel 120 pushes the glass 3000 to adjust its position until the positioning end 111 abuts against the fixture body 2000. This avoids damage to the surface of the glass 3000 while ensuring positioning accuracy.

[0029] In an alternative embodiment, such as Figure 1 As shown, the glass fixture centering and positioning device 1000 also includes a floating joint 600, and the connecting seat 110 is connected to the electric cylinder 300 through the floating joint 600. In this embodiment, the floating joint 600 serves as a connection device between the electric cylinder 300 and the connecting seat 110, ensuring that the driving force of the electric cylinder 300 is transmitted in a preset direction, avoiding positioning deviations caused by operational jamming, thereby ensuring the accurate detection of force values ​​by the sensor 400.

[0030] In an alternative embodiment, such as Figure 1 As shown, the glass fixture centering and positioning device 1000 also includes an electric cylinder base 330 and an electric cylinder protective sleeve 340. The electric cylinder 300 is mounted on the electric cylinder base 330, and the electric cylinder protective sleeve 340 covers the outside of the electric cylinder 300. In this embodiment, the electric cylinder base 330 ensures that the axis of the electric cylinder 300 is parallel to the extension direction of the guide rail 200 after installation, avoiding deviation of the electric cylinder 300 and thus avoiding deviation of the driving force direction. The electric cylinder protective sleeve 340 covers the cylinder body 320 of the electric cylinder 300 and the connection between the cylinder body 320 and the piston rod 310, effectively preventing debris from entering the gap between the piston rod 310 and the cylinder body 320, and preventing the piston rod 310 from jamming and affecting the positioning accuracy.

[0031] In an alternative embodiment, such as Figure 1As shown, the glass fixture centering and positioning device 1000 also includes a controller (not shown in the figure). The controller is connected to the electric cylinder 300 and the sensor 400 respectively. The controller can control the force output by the electric cylinder 300 according to the detection result of the sensor 400. In this embodiment, the controller adjusts the start and / or stop of the electric cylinder according to the force signal fed back by the sensor 400, thereby achieving precise control of the force value, avoiding centering and positioning deviations caused by glass deformation or unstable positioning due to improper force value, and ensuring that the repeatability of the device meets the high-precision detection requirement of ±0.1mm.

[0032] In an alternative embodiment, such as Figure 1 As shown, the positioning component 100 also includes a fixing block 130, and the positioning wheel 120 is connected to the connecting seat 110 through the fixing block 130 and is located above the connecting seat 110.

[0033] In an alternative embodiment, such as Figure 1 As shown, the fixing block 130 is connected to the connecting base 110 via the mounting base 150.

[0034] In an alternative embodiment, such as Figure 1 As shown, the positioning wheel 120 is rotatably mounted on the fixed block 130, and the rotation axis of the positioning wheel 120 is parallel to the vertical direction.

[0035] In an alternative embodiment, such as Figure 1 As shown, the locking element 500 includes a clamp 510, which moves synchronously with the connecting seat 110. In this embodiment, the clamp 510 moves with the connecting seat 110 and locks immediately after the positioning component 100 reaches the preset position to prevent displacement after positioning, ensuring that the glass remains centered during the detection process and avoiding deviations in the detection results due to positional offset. It is understood that the clamp 510 can be electrically connected to the controller.

[0036] In an alternative embodiment, such as Figure 1 As shown, the locking member 500 also includes a buffer pad 520, which is disposed between the clamp 510 and the connecting seat 110. In this embodiment, the buffer pad 520 is fixed to the side of the clamp 510 facing the connecting seat 110 by adhesive bonding. When the clamp 510 receives a locking signal, the buffer pad 520 first contacts the connecting seat 110 and absorbs the impact force at the moment of locking through its own elastic deformation, thus preventing the connecting seat 110 from undergoing slight displacement due to the impact.

[0037] In an alternative embodiment, such as Figure 1As shown, the extension direction of the guide rail 200 is parallel to the axial direction of the electric cylinder 300. In this embodiment, by controlling the extension direction of the guide rail 200 to be parallel to the axial direction of the electric cylinder 300, it can be ensured that the trajectory of the positioning component 100 moving along the guide rail is a straight line, avoiding positioning offset caused by lateral force.

[0038] In an alternative embodiment, such as Figure 1 As shown, the glass inspection fixture centering and positioning device 1000 also includes a guide rail base 210, on which the guide rail 200 is disposed.

[0039] In an alternative embodiment, such as Figure 1 As shown, sensor 400 is built into electric cylinder 300. In this embodiment, the sensor 400 is built into electric cylinder 300, which can reduce the interference of the external environment on sensor 400; at the same time, it simplifies the device structure, reduces external wiring, and reduces the difficulty of installation and maintenance of the device.

[0040] An embodiment of this utility model also provides a glass inspection fixture, such as... Figure 2 As shown, the glass inspection fixture includes the glass inspection fixture centering and positioning device 1000 of any of the aforementioned embodiments. In this embodiment, the glass inspection fixture integrates the glass inspection fixture centering and positioning device 1000, which can achieve precise centering of the glass on the fixture body, solve the problem of inaccurate positioning of traditional fixtures, improve the reliability of glass inspection results, and make the repeatability of the inspection reach ±0.1mm.

[0041] In an alternative embodiment, such as Figure 2 As shown, the glass inspection fixture also includes the fixture body 2000 and the glass 3000.
