DETAILED DESCRIPTION

[0027] ​In order for those skilled in the art to better understand the technical solutions in the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in the following with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the present disclosure.

[0028] With reference to Figure 1 and Figure 2 , the positioning calibration device in an embodiment of the present disclosure comprises a box body 1, a plurality of support pieces 2 arranged in the box body 1, and a calibration assembly 3 arranged in cooperation. The inside of the box body 1 can form a vacuum environment, the plurality of support pieces 2 are arranged with a spacing therebetween, for jointly supporting a panel (as shown by a in Figure 2 , and the calibration assembly 3 is used for calibrating the position of the panel.

[0029] With reference to Figure 2 , two gate valves 4 are arranged on the two sides of the box body 1, respectively, for interfacing with upstream and downstream devices. Specifically, when the gate valve 4 interfacing with the upstream device is opened and the gate valve 4 interfacing with the downstream device is closed, at this time, the inside of the box body 1 is in a normal pressure state, and the panel can be placed on the support pieces 2. When both of the gate valves 4 are closed, at this time, the box body 1 can be vacuumized, and the position of the panel can be calibrated through the calibration assembly 3. When the gate valve 4 interfacing with the upstream device is closed and the gate valve 4 interfacing with the downstream device is opened, at this time, the panel located in the box body 1 can be taken out. It should be noted that in the present embodiment, the downstream device, the box body 1 and the communication therebetween all maintain a vacuum environment.

[0030] Among them, the plurality of support pieces 2 are arranged with a spacing therebetween, for jointly supporting the panel. Compared with the panel being directly placed on a conveying belt or the like in the prior design, the spacing arrangement of the support pieces 2 can facilitate the upstream and downstream devices to take and place the panel, and the support of the support pieces 2 to the panel can make the panel be calibrated in a static state, so as to effectively ensure the calibration accuracy. The positions and the number of the support pieces 2 can be arranged according to the size of the panel, and the plurality of support pieces 2 can be arranged in a rectangular array, so as to effectively support the panel.

[0031] In the present embodiment, since the panel sent into the box body 1 by the upstream feeding device has a certain position error, it is necessary to calibrate it through the calibration assembly 3, so as to facilitate the downstream taking device to accurately take the material at the corresponding position. In the present embodiment, the panel is exemplarily described by taking the screen of various electronic devices as an example, and in other embodiments, the panel can also be a panel structure in other fields.

[0032] With reference to Figure 1 andFigure 2 The box 1 is communicated with a butterfly valve 5, which can be connected with a vacuum pump to form a vacuum environment in the box 1. The box 1 is provided with a vacuum gauge to measure the vacuum degree, so that the vacuum degree in the box 1 can be obtained in real time to adjust the vacuum degree. In the embodiment, the vacuum environment formed in the box 1 can ensure that the interior is in a high cleanliness state to reduce the influence of particles on the panel. Further, the box 1 is also communicated with a pneumatic valve 6, which can be used for later vacuum breaking, so that the interior of the box 1 changes from a vacuum state to a normal pressure state.

[0033] Referring to Figure 1 In an optional embodiment, the box 1 is provided with an observation window to observe the interior, so that the working environment and the calibration process in the interior can be observed in real time.

[0034] Referring to Figures 3 to 5 The calibration assembly 3 includes a driving member 31, a movable sealing member 32 and positioning members 33. The driving member 31 is arranged outside the box 1, the movable sealing member 32 is sealingly arranged on the side wall of the box 1, and the positioning members 33 are arranged in the box 1. The movable sealing member 32 is drivingly connected with the driving member 31 and the positioning members 33. The positioning members 33 are provided in two, and the driving member 31 can drive the two positioning members 33 to abut and calibrate the panel on the support 2 from two different directions. In the embodiment, the driving member 31 can be a driving structure such as a pneumatic cylinder or an electric cylinder. Since the driving member 31 operates in a vacuum environment, the driving member 31 and the positioning members 33 are drivingly connected through the movable sealing member 32 to ensure that the driving member 31 can drive the two positioning members 33 to abut and calibrate the panel from two different directions, thereby ensuring the calibration accuracy. Compared with the prior art, the calibration accuracy is further improved by abutting and calibrating the panel from two different directions.

[0035] Referring to Figure 4 and Figure 5 The calibration assembly 3 can also include an adapter rod 34 connected with the movable sealing member 32, and the positioning members 33 are fixed on the adapter rod 34. The two positioning members 33 have a spacing for the corners of the panel to pass through, and the two positioning members 33 can abut the two adjacent sides of the panel under the action of the driving member 31. Therefore, the panel can be abutted and calibrated from two different directions by the two positioning members 33. In an optional embodiment, the calibration assembly 3 is provided in at least two groups, and the at least two groups of calibration assemblies are arranged at two opposite corners of the box 1. On this basis, the calibration assembly 3 can also be provided in three groups and arranged at three corners in the box 1. In the embodiment, the calibration assembly 3 is provided in four groups and arranged at four corners of the box 1 to abut and calibrate the panel. By arranging the above four groups of calibration assemblies 3, the panel can be accurately positioned.

[0036] Meanwhile, the positioning member 33 in the embodiment can be a limiting post, and only one driving member 31 is needed to drive one adapter rod 34 to move, so that the two limiting posts abut against the panel from two different directions. Compared with driving two positioning members 33 to abut against the calibration panel from two different directions by two driving members 31 respectively, the structure design in the embodiment is simple and ingenious, low in cost, good in control effect, and small in requirement for the size of the space inside the box 1.

[0037] With reference to Figure 3 and Figure 4 , the calibration assembly 3 further comprises a first connecting rod 35 and a second connecting rod 36 which are hingedly connected at the ends, and the movable sealing member 32 comprises an outer cylinder and an inner rod which are sealingly arranged and rotatable relative to each other, the outer cylinder is fixed to the side wall of the box 1, the other end of the first connecting rod 35 is connected with the output end of the driving member 31, the other end of the second connecting rod 36 is connected with one end of the inner rod, the other end of the inner rod is connected with the adapter rod 34, and the driving member 31 drives the positioning member 33 to rotate close to or away from the panel through the first connecting rod 35 and the second connecting rod 36. In the embodiment, the movable sealing member 32 can be a magnetic fluid, which has the characteristics of enabling the inner rod to rotate and maintaining good sealing effect, and further ensuring the vacuum environment inside the box 1, i.e., the movable sealing member 32 occupies a small internal space of the box 1.

[0038] Therefore, during operation, the driving member 31 can drive the first connecting rod 35 to move, so as to drive the second connecting rod 36 to move through the first connecting rod 35, so that the inner rod drives the adapter rod 34 inside the box 1 to rotate, thereby enabling the positioning member 33 to rotate close to or away from the panel.

[0039] With reference to Figure 4 and Figure 5 , the box 1 is provided with a mounting groove 11 in the side wall adjacent to the corner, and the adapter rod 34 comprises a first segment and a second segment which are bent relative to each other, the first segment is located in the mounting groove 11, the second segment is bent towards the corner of the box 1 and located in the cavity of the box 1, and the second segment is provided with the positioning member 33. In the embodiment, the bent design of the adapter rod 34 enables the adapter rod 34 to avoid interference with the box 1 as much as possible when the adapter rod 34 is installed in the relatively small box 1. Meanwhile, the design of the mounting groove 11 also enables the adapter rod 34 to occupy the internal space of the box 1 as little as possible. Therefore, the calibration assembly 3 in the application can be adapted to a small box 1, and the small box 1 has a fast vacuumizing speed, which can further speed up the process flow and improve work efficiency.

[0040] With reference to Figure 5The adapter rod 34 has an elongated hole, through which two positioning members 33 are fitted and installed. Therefore, the positioning members 33 can be installed at different positions on the elongated hole according to the actual panel size requirements, thereby adjusting the distance between the two positioning members 33. It is understood that in other embodiments, two mounting holes with a fixed spacing can also be designed for installing the two positioning members 33. This application does not impose any limitations on this.

[0041] Reference Figure 3 One end of the adapter rod 34 has an assembly hole, and one end of the movable seal 32 is provided with a fastener 37. The fastener 37 passes through the assembly hole to clamp the adapter rod 34 to the movable seal 32. The fastener 37 can be a bolt or nut.

[0042] Reference Figure 2 The positioning calibration device in this embodiment also includes an optical sensor 7. A through slot 12 is provided in the housing 1, and a light-transmitting plate 8 is installed at the through slot 12. A reflector 9 is installed on the inner wall of the housing 1 opposite to the inner wall with the through slot 12. Light emitted by the optical sensor 7 can be transmitted through the light-transmitting plate 8, pass through the side area of ​​the panel, and be reflected by the reflector 9 and transmitted back to the optical sensor 7 by the light-transmitting plate 8. A bracket can be installed at the bottom of the housing, and the optical sensor 7 can be mounted on the bracket. Multiple sets of optical sensors 7, light-transmitting plates 8, and reflectors 9 can be correspondingly arranged to perform fragment detection on different areas of the panel, ensuring the accuracy of the detection results.

[0043] After the panel is mounted on the support 2, light emitted by the optical sensor 7 travels along the aforementioned light path through the panel to detect the presence of any broken pieces. It should be noted that the broken pieces exist in the edge region of the panel. Therefore, in this embodiment, the light path of the optical sensor 7 is configured to pass through the side region of the panel. Specifically, in this embodiment, the optical sensor 7 detects broken pieces by analyzing the parameter changes of the refracted and returned light.

[0044] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature or implementation described herein. The specification can include implicit combinations of explicitly mentioned features and / or implicit combinations of implicitly mentioned features. Such combinations are also expressly included within the scope of the specification and an embodiment.
