Description

Technical Field

[0001] This utility model relates to the field of display device manufacturing technology, and in particular to a panel fixing device. Background Technology

[0002] On the panel production line, such as Figure 1 As shown, tray 1' is typically used to support panel 2', and tray 1' moves panel 2' horizontally. After panel 2' is manufactured, it is necessary to inspect the coated area 21' of panel 2' on tray 1' for defects such as pinholes, lines, or streaks. Before inspection, panel 2' needs to be tilted to facilitate inspection.

[0003] In the prior art, since there is no fixed connection between the tray 1′ and the panel 2′, and there is no limiting structure on the tray 1′ to restrict the movement of the panel 2′ (the limiting structure will damage the panel 2′ if it collides with the outer periphery of the panel 2′), if the tray 1′ is tilted, the panel 2′ in the tilted state will slide down the tilted tray 1′ under its own weight, causing the panel 2′ to fall and be damaged. Utility Model Content

[0004] The purpose of this invention is to provide a panel fixing device that can stably fix the panel on the tray without obstructing the coated area of ​​the panel.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A panel fixing device is provided, comprising:

[0007] A tray for supporting a panel, the panel having uncoated areas at two edges along a first direction;

[0008] The tray is provided with a set of fixing mechanisms for each of the non-coated areas. Each set of fixing mechanisms includes a pressure plate, an adsorption structure, and a locking structure. The length of the pressure plate extends along a second direction. The adsorption structure is installed on the side of the pressure plate facing the tray. The pressure plate can move to the non-coated area of ​​the panel or move to be completely offset from the panel. When the pressure plate moves above the non-coated area of ​​the panel, the adsorption structure can adsorb and fix it to the non-coated area. The two ends of the pressure plate along the second direction extend beyond the edge of the panel and can be detachably connected to the tray through a set of locking structures. The first direction and the second direction are set at an angle.

[0009] As a further embodiment of the panel fixing device, the locking structure includes a first magnetic suction part and a second magnetic suction part. The first magnetic suction part is installed at the bottom of the pressure plate. The pressure plate is provided with a first magnetic suction part on each of its two edges along the second direction. The tray is equipped with a second magnetic suction part that corresponds one-to-one with the first magnetic suction part. The second magnetic suction part is located below the first magnetic suction part. The first magnetic suction part can magnetically engage with the second magnetic suction part.

[0010] As a further embodiment of the panel fixing device, the fixing mechanism further includes a first limiting side plate. Each second magnetic suction part is provided with a first limiting side plate on at least one side of its two sides along the first direction. The end of the first limiting side plate opposite to the tray protrudes from the upper surface of the second magnetic suction part. When the first magnetic suction part and the second magnetic suction part are magnetically attracted to each other, the pressure plate contacts one side of the first limiting side plate along the first direction.

[0011] As a further embodiment of the panel fixing device, the locking structure also includes a plurality of third magnetic suction parts that correspond one-to-one with the second magnetic suction parts. The third magnetic suction parts are installed on the tray and are spaced apart from the second magnetic suction parts along the first direction. When the pressure plate moves to the point where the first magnetic suction part and the third magnetic suction part magnetically engage, the pressure plate is completely offset from the panel.

[0012] As a further embodiment of the panel fixing device, the fixing mechanism further includes a second limiting side plate. Each of the third magnetic suction parts is provided with a second limiting side plate on at least one side of the two sides along the first direction. The end of the second limiting side plate opposite to the tray protrudes from the upper surface of the third magnetic suction part. When the first magnetic suction part and the third magnetic suction part are magnetically attracted to each other, the pressure plate contacts one side of the second limiting side plate along the first direction.

[0013] As a further embodiment of the panel fixing device, the fixing mechanism further includes a limiting baffle. The second magnetic suction part is provided with a first limiting side plate on the side opposite to the third magnetic suction part, and the third magnetic suction part is provided with a second limiting side plate on the side opposite to the second magnetic suction part. The first limiting side plate is connected to the second limiting side plate through the limiting baffle. The limiting baffle is parallel to the tray, and the limiting baffle and the pressure plate are spaced apart in the vertical direction.

[0014] As a further embodiment of the panel fixing device, the fixing mechanism also includes a clamping structure, which is installed on the limiting baffle and located above the second magnetic part. When the first magnetic part and the second magnetic part are magnetically attracted to each other, the clamping structure can clamp against the side of the pressure plate away from the first magnetic part.

[0015] As a further embodiment of the panel fixing device, the clamping structure includes a screw, an abutment plate, and a first locking nut. The screw passes through the limiting baffle. The abutment plate and the first locking nut are located between the limiting baffle and the second magnetic attraction part. The abutment plate is fixedly connected to the lower end of the screw. When the first magnetic attraction part and the second magnetic attraction part are magnetically attracted to each other, the first locking nut can be screwed onto the screw until it abuts against the lower surface of the limiting baffle, so that the abutment plate abuts against the side of the pressure plate away from the first magnetic attraction part.

[0016] As a further embodiment of the panel fixing device, the locking structure further includes a mounting base, a fastener, and a guide structure that guides along the first direction. The guide structure is located on the tray. The mounting base corresponds one-to-one with the second magnetic part. The second magnetic part is mounted on the mounting base. Each mounting base is connected to one of the guide structures and fixed to the tray by one of the fasteners.

[0017] As a further embodiment of the panel fixing device, the tray is provided with a sliding groove, the length of which extends along the first direction. The bottom of the mounting base is provided with a slider, which slides in cooperation with the sliding groove. The slider and the sliding groove constitute the guide structure. The two end faces of the tray along the second direction are provided with adjustment elongated holes corresponding to the sliding grooves. The length of the adjustment elongated holes extends along the first direction. The slider is provided with a threaded connection hole on the side facing the adjustment elongated hole. The fastener is a screw, which can pass through the adjustment elongated hole and be screwed into the threaded connection hole for fixing.

[0018] The advantages of this utility model compared to the prior art are:

[0019] The panel fixing device of this invention can stably fix the panel to the tray before the tray is tilted, preventing the panel from slipping and being damaged due to relative movement between the panel and the tray during the tilting process. It also prevents the pressure plate from obstructing the coating area of ​​the panel, thus not affecting the panel inspection. After the panel inspection is completed, the locking structure is released, and the pressure plate is moved to be completely offset from the panel, allowing the panel to be transferred away.

[0038] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0039] The present invention will now be described in detail with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 2 to 5 As shown, this utility model embodiment provides a panel fixing device, including a tray 1 and a fixing mechanism 2.

[0042] The tray 1 supports the panel 100, which has non-coated areas 110 along its two edges in a first direction. In this embodiment, in addition to the non-coated areas 110 along the two edges in the first direction, the panel 100 also has non-coated areas 110 along its two edges in a second direction. The area between the four non-coated areas 110 is the coated area 120, i.e., the target detection area. The present invention will be further explained below using the example of fixing the non-coated areas 110 along the two edges in the first direction using a panel fixing device (hereinafter, the non-coated areas 110 refer to the non-coated areas 110 at the two edges in the first direction).

[0043] A set of fixing mechanisms 2 is provided on the tray 1 for each non-coated area 110. Each set of fixing mechanisms 2 includes a pressure plate 21, an adsorption structure 22 and a locking structure 23. The length of the pressure plate 21 extends along the second direction. The adsorption structure 22 is installed on the side of the pressure plate 21 facing the tray 1. The pressure plate 21 can be moved to the non-coated area 110 of the panel 100 or moved to be completely offset from the panel 100. When the pressure plate 21 moves above the non-coated area 110 of the panel 100, the adsorption structure 22 can adsorb and fix with the non-coated area 110. The two ends of the pressure plate 21 along the second direction extend beyond the edge of the panel 100 and can be detachably connected to the tray 1 through a set of locking structures 23 respectively. The first direction and the second direction are set at an angle.

[0044] Understandably, before tilting the tray 1, the two pressure plates 21 are first moved above the two non-coated areas 110 of the panel 100 along the first direction. Then, the pressure plates 21 are adsorbed and fixed to the non-coated areas 110 of the panel 100 by the adsorption structure 22. Finally, the two ends of the pressure plates 21 along their length are locked and fixed to the tray 1 by a set of locking structures 23. Figure 2 As shown, the panel 100 can be fixed to the tray 1 by the fixing mechanism 2. The panel fixing device of this embodiment can stably fix the panel 100 to the tray 1, avoid the relative movement between the panel 100 and the tray 1 during the tilting of the tray 1, which would cause the panel 100 to slip and be damaged, and prevent the pressure plate 21 from blocking the coating area 120 of the panel 100.

[0045] In this embodiment, after the panel 100 has been inspected, as shown in Figure 5, when the pressure plate 21 is moved to a position completely offset from the panel 100, the panel 100 can be transferred away. Therefore, in this embodiment, a locking structure 23 is used to detachably connect the end of the pressure plate 21 to the tray 1, which facilitates the disassembly of the pressure plate 21.

[0046] like Figure 4 As shown, the adsorption structure 22 includes multiple suction cups 221. Multiple suction cups 221 are evenly installed at intervals along the second direction below each pressure plate 21. The panel 100 can be stably adsorbed by the multiple suction cups 221.

[0047] For example, panel 100 has a rectangular structure, with both the first and second directions being straight lines that are perpendicular to each other. The first direction is the X direction shown in the figure, and the second direction is the Y direction shown in the figure. In other embodiments, panel 100 may also have an elliptical or circular structure (not shown in the figure), with the corresponding first direction being a straight line and the second direction being an arc.

[0048] Furthermore, the locking structure 23 includes a first magnetic attraction part 231 and a second magnetic attraction part 232. The first magnetic attraction part 231 is installed at the bottom of the pressure plate 21. The pressure plate 21 is provided with a first magnetic attraction part 231 on each of its two edges along the second direction. The tray 1 is provided with a second magnetic attraction part 232 that corresponds one-to-one with the first magnetic attraction part 231. The second magnetic attraction part 232 is located below the first magnetic attraction part 231. The first magnetic attraction part 231 can magnetically engage with the second magnetic attraction part 232.

[0049] When the first magnetic suction part 231 below the pressure plate 21 magnetically engages with the second magnetic suction part 232 on the tray 1, the connection between the pressure plate 21 and the tray 1 can be achieved, thereby allowing the panel 100 to be fixed to the tray 1 by the adsorption structure 22 below the pressure plate 21. Using a magnetic attraction method provides reliable connection stability and facilitates the separation of the pressure plate 21 from the tray 1. After releasing the adsorption structure 22 from the non-coated area 110 of the panel 100, the pressure plate 21 can be transferred away.

[0050] The first magnetic suction part 231 can protrude from the lower surface of the pressure plate 21, and the second magnetic suction part 232 can protrude from the upper surface of the tray 1. When the first magnetic suction part 231 and the second magnetic suction part 232 are magnetically fixed, the adsorption structure 22 below the pressure plate 21 can stably adsorb the non-coated area 110 of the panel 100 and stably fix the panel 100 on the tray 1.

[0051] In this embodiment, as Figure 2 and Figure 3 As shown, the fixing mechanism 2 also includes a first limiting side plate 24. Each second magnetic suction part 232 has a first limiting side plate 24 on at least one side of its two sides along the first direction. The end of the first limiting side plate 24 facing away from the tray 1 protrudes from the upper surface of the second magnetic suction part 232. When the first magnetic suction part 231 and the second magnetic suction part 232 are magnetically attracted together, the pressure plate 21 contacts one side of the first limiting side plate 24 along the first direction.

[0052] The first limiting side plate 24 is disposed on one side of the second magnetic suction part 232 along the first direction, and is used to limit the pressure plate 21. When the pressure plate 21 contacts the side of the first limiting side plate 24, the pressure plate 21 can be positioned directly above the non-coated area 110 of the panel 100 without obstructing the coated area 120 of the panel 100.

[0053] For example, the second magnetic attraction portion 232 faces one end of the non-coated area 110 of the panel 100 along the first direction, and the first limiting side plate 24 is located on the side of the second magnetic attraction portion 232 adjacent to the coated area 120 of the panel 100 along the first direction. In other embodiments, the first limiting side plate 24 may also be located on the side of the second magnetic attraction portion 232 away from the coated area 120 of the panel 100 along the first direction (not shown in the figure), or a first limiting side plate 24 (not shown in the figure) may be provided on both sides of the second magnetic attraction portion 232 along the first direction.

[0054] Furthermore, the locking structure 23 of this embodiment also includes a plurality of third magnetic parts 233 corresponding one-to-one with the second magnetic parts 232. The third magnetic parts 233 are mounted on the tray 1 and are spaced apart from the second magnetic parts 232 along the first direction. When the pressure plate 21 moves to the point where the first magnetic parts 231 and the third magnetic parts 233 magnetically engage, the pressure plate 21 is completely misaligned with the panel 100.

[0055] In this embodiment, the third magnetic part 233 is magnetically fixed to the pressure plate 21 that is completely offset from the panel 100, so as to prevent the pressure plate 21 from falling off the tray 1 and being damaged after being separated from the second magnetic part 232.

[0056] Furthermore, the fixing mechanism 2 also includes a second limiting side plate 25. Each third magnetic suction part 233 has a second limiting side plate 25 on at least one side of its two sides along the first direction. The end of the second limiting side plate 25 facing away from the tray 1 protrudes from the upper surface of the third magnetic suction part 233. When the first magnetic suction part 231 and the third magnetic suction part 233 are magnetically attracted together, the pressure plate 21 contacts one side of the second limiting side plate 25 along the first direction. When the first magnetic suction part 231 and the second magnetic suction part 232 below the pressure plate 21 separate and the adsorption structure 22 separates from the non-coated area 110 of the panel 100, the pressure plate 21, the first magnetic suction part 231, and the adsorption structure 22 move together to contact one side of the second limiting side plate 25 along the first direction and move downward until the first magnetic suction part 231 and the third magnetic suction part 233 are magnetically attracted together, thereby fixing the pressure plate 21, which is completely offset from the panel 100, onto the tray 1.

[0057] For example, such as Figure 2 and Figure 3 As shown, the second limiting side plate 25 is located on the side of the third magnetic attraction portion 233 opposite to the second magnetic attraction portion 232. In other embodiments, the second limiting side plate 25 may also be located on one side of the groove-shaped second magnetic attraction portion 232 of the third magnetic attraction portion 233 (not shown in the figure), or a second limiting side plate 25 (not shown in the figure) may be provided on both sides of the third magnetic attraction portion 233 along the first direction.

[0058] Furthermore, the fixing mechanism 2 also includes a limiting baffle 26. The second magnetic suction part 232 is provided with a first limiting side plate 24 on the side opposite to the third magnetic suction part 233, and the third magnetic suction part 233 is provided with a second limiting side plate 25 on the side opposite to the second magnetic suction part 232. The first limiting side plate 24 is connected to the second limiting side plate 25 through the limiting baffle 26. The limiting baffle 26 is parallel to the tray 1, and the limiting baffle 26 and the pressure plate 21 are spaced apart in the vertical direction.

[0059] By setting a limiting baffle 26 and connecting the upper end of the first limiting side plate 24 located on the side of the second magnetic suction part 232 away from the third magnetic suction part 233 and the upper end of the second limiting side plate 25 located on the side of the third magnetic suction part 233 away from the second magnetic suction part 232, when the pressure plate 21 is pulled up to separate the first magnetic suction part 231 from the second magnetic suction part 232 or the third magnetic suction part 233, the limiting baffle 26 can limit the upward movement of the pressure plate 21, so that the movement of the two ends of the pressure plate 21 along its length direction is consistent, and avoid the pressure plate 21 moving too much at one end, causing the other end of the pressure plate 21 to collide with the panel 100 and damage the panel 100.

[0060] Example 2

[0061] This embodiment is a further improvement upon Embodiment 1 described above. For example... Figures 6 to 8 As shown, in order to improve the stability of the panel 100 when the tray 1 is tilted, this embodiment adds a clamping structure 27 based on the above embodiment one.

[0062] Exemplarily, the fixing mechanism 2 of this embodiment further includes a clamping structure 27, which is mounted on the limiting baffle 26 and located above the second magnetic attraction part 232. When the first magnetic attraction part 231 and the second magnetic attraction part 232 are magnetically attracted together, the clamping structure 27 can clamp against the side of the pressure plate 21 away from the first magnetic attraction part 231. After the first magnetic attraction part 231 and the second magnetic attraction part 232 are magnetically fixed, the clamping structure 27 mounted on the limiting baffle 26 can selectively abut against the upper surface of the pressure plate 21, thereby improving the magnetic attraction stability between the first magnetic attraction part 231 and the second magnetic attraction part 232. When it is necessary to move the pressure plate 21 to be completely offset from the panel 100, first release the clamping structure 27 from the pressure plate 21, then pull up the pressure plate 21 and move the pressure plate 21 above the third magnetic attraction part 233, so that the first magnetic attraction part 231 and the third magnetic attraction part 233 are magnetically fixed.

[0063] The clamping structure 27 includes a screw 271, an abutment plate 272, and a first locking nut 273. The screw 271 passes through the limiting baffle 26. The abutment plate 272 and the first locking nut 273 are located between the limiting baffle 26 and the second magnetic attraction part 232. The abutment plate 272 is fixedly connected to the lower end of the screw 271. When the first magnetic attraction part 231 and the second magnetic attraction part 232 are magnetically attracted, the first locking nut 273 can be screwed onto the screw 271 to abut against the lower surface of the limiting baffle 26, so that the abutment plate 272 abuts against the side of the pressure plate 21 away from the first magnetic attraction part 231.

[0064] Understandably, the first locking nut 273 is first screwed onto the screw 271, and the screw 271 is passed through the pre-drilled clearance hole 261 on the limiting baffle 26. Then, the first locking nut 273 is tightened until it abuts against the lower surface of the limiting baffle 26. At this time, the abutting plate 272 abuts against the upper surface of the pressure plate 21, which can improve the magnetic attraction stability between the first magnetic attraction part 231 and the second magnetic attraction part 232. When the first locking nut 273 is tightened in the opposite direction, the magnetic attraction can be released. In addition to the contact between the abutting plate 272 and the pressure plate 21, the magnetic attraction between the first magnetic attraction part 231 and the second magnetic attraction part 232 and the attraction of the adsorption structure 22 to the non-coated area 110 of the panel 100 can be released by pulling up the pressure plate 21. Then, the pressure plate 21 is moved above the third magnetic attraction part 233. At this time, the pressure plate 21 is completely misaligned from the panel 100. The magnetic attraction between the first magnetic attraction part 231 and the third magnetic attraction part 233 can fix the pressure plate 21, which is completely misaligned from the panel 100, onto the tray 1.

[0065] Furthermore, the clamping structure 27 also includes a second locking nut 274. The second locking nut 274 is located above the limiting baffle 26 and is screwed onto the screw 271. When it is necessary to release the clamping structure 27 from the pressure plate 21, the second locking nut 274 can suspend the screw 271, the abutment plate 272 and the first locking nut 273, preventing the screw 271, the abutment plate 272 and the first locking nut 273 from falling off the limiting baffle 26, thus improving the ease of operation.

[0066] Example 3

[0067] This embodiment is basically the same as the first or second embodiment described above, except that the locking structure 23 has been further improved.

[0068] like Figures 9 to 11As shown, the locking structure 23 of this embodiment is further provided with a mounting base 234, a fastener 235 and a guide structure 236 that plays a guiding role along the first direction, based on the first embodiment described above. The guide structure 236 is located on the tray 1. The mounting base 234 corresponds one-to-one with the second magnetic part 232. The second magnetic part 232 is mounted on the mounting base 234. Each mounting base 234 is connected to a guide structure 236 and fixed to the tray 1 by a fastener 235.

[0069] Understandably, the second magnetic attraction part 232 is mounted on the mounting base 234 and can move along the first direction under the action of the guide structure 236. This structure allows the panel fixing device of this embodiment to be adapted to fixing panels 100 of various sizes. Specifically, the mounting base 234 can be moved according to the size of the panel 100 and the position of the non-coated area 110 on the tray 1, so that the second magnetic attraction part 232 on the mounting base 234 is directly opposite one end of the non-coated area 110 along the second direction. Then, the mounting base 234 can be fixed by the fastener 235.

[0070] For example, such as Figure 10 and Figure 11 As shown, a slide groove 2361 is provided on the tray 1, and the length of the slide groove 2361 extends along the first direction. A slider 2362 is provided at the bottom of the mounting base 234. The slider 2362 slides in cooperation with the slide groove 2361. The slider 2362 and the slide groove 2361 form a guide structure 236. Adjustment elongated holes 11 corresponding to the slide groove 2361 are provided on both ends of the tray 1 along the second direction. The length of the adjustment elongated holes 11 extends along the first direction. A threaded connection hole 23621 is provided on the side of the slider 2362 facing the adjustment elongated hole 11. The fastener 235 is a screw. The screw can pass through the adjustment elongated hole 11 and be screwed and fixed to the threaded connection hole 23621.

[0071] The slider 2362 at the bottom of the mounting base 234 slides in conjunction with the slide groove 2361, thereby pushing the slider 2362 along the first direction and causing the second magnetic suction part 232 on the mounting base 234 to move synchronously. After the position of the second magnetic suction part 232 is adjusted, a screw is screwed through the adjustment elongated hole 11 into the threaded connection hole 23621 on the slider 2362 until the screw abuts against the tray 1, thereby locking the slider 2362 and preventing the mounting base 234 from moving along the first direction, which would affect the adsorption structure 22 at the bottom of the pressure plate 21 to adsorb and fix the non-coated area 110 of the panel 100, while also preventing the pressure plate 21 from covering the coated area 120 of the panel 100.

[0072] refer to Figure 7 In the case where the abutting structure 27 is provided in Embodiment 2, in order to adapt the abutting structure 27 to the sliding structure design of the second magnetic suction part 232, this embodiment designs the clearance hole 261 as an elongated hole whose length extends along the first direction (see reference). Figure 12 Adjust the position of the clamping structure 27 according to the position of the second magnetic suction part 232 so that the abutting plate 272 of the clamping structure 27 is located directly above the second magnetic suction part 232, so that the upper surface of the pressure plate 21 can be abutted by the clamping structure 27.

[0073] In other embodiments, the locking structure 23 may also adopt a suction cup structure (not shown in the figure).
