Description

Technical Field

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

[0002] During the manufacturing process of display devices, a protective film is glued to the surface of the panel for protection purposes. After the film is applied to a large number of panels, random sampling inspections are required to determine the adhesion between the protective film and the panel.

[0003] Currently, sampling inspection of the protective film adhesion is usually done manually. Workers place the panel 2' with the protective film 1' applied on a workbench 3', then manually peel off the protective film 1' to separate it from the panel 2'. The adhesion is then judged by visually inspecting the surface of the panel 2' after peeling, checking for any remaining adhesive. This existing technology has the following drawbacks: repeated manual peeling and visual inspection are tiring, time-consuming, labor-intensive, and inefficient. Furthermore, it is prone to misjudging whether adhesive residue is present, making it difficult to guarantee inspection accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a panel inspection device with a simple structure that can automatically peel off the film and inspect, thereby improving production efficiency and inspection accuracy.

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

[0006] A panel inspection device is provided, comprising a support base, a release film lifting mechanism, a peeling mechanism, and an inspection mechanism. The support base is used to support a panel to be peeled. The release film lifting mechanism is used to lift the edge of the release film on the panel to be peeled, causing the release film to partially curl up to form a raised edge. The peeling mechanism is disposed above the support base and includes a first driving member and a peeling assembly. The peeling assembly is used to grasp the raised edge. The first driving member is convexly connected to the peeling assembly to drive the peeling assembly and the raised edge to move away from the release film lifting mechanism, thereby separating the release film from the panel to be peeled. The inspection mechanism is spaced apart on one side of the peeling mechanism along the horizontal direction and is used to inspect the adhesive residue on the surface of the panel after the release film is peeled off.

[0007] As a preferred embodiment of the panel inspection device, the film-lifting mechanism includes a mounting frame, a second driving member, and a film-lifting assembly. The mounting frame is disposed on one side of the support base along the horizontal direction. The second driving member is disposed on the mounting frame and located above the support base. The second driving member is used to drive the film-lifting assembly to move in the vertical direction. The film-lifting assembly can abut against the panel to be peeled. The film-lifting assembly includes a third driving member and a film-lifting element. The third driving member is disposed at the driving end of the second driving member and is convexly connected to the film-lifting element. The film-lifting element can separate part of the release film from the panel to be peeled to form the lifting edge by moving along a first direction. The first direction is set at an angle to the vertical direction.

[0008] As a preferred embodiment of the panel inspection device, the film-removing component includes a film-removing blade with an inclined surface. The inclined surface slopes downward from one end adjacent to the second driving member toward the end away from the second driving member. The film-removing blade can be inserted between the release film and the panel to be peeled, so that a portion of the release film separates from the panel to be peeled along the inclined surface.

[0009] As a preferred embodiment of the panel inspection device, the film-forming mechanism further includes a mounting base and a first elastic element. The third driving element is disposed on the bottom side of the mounting base, and the first elastic element is disposed on the top side of the mounting base. The side of the first elastic element away from the mounting base is connected to the driving end of the second driving element.

[0010] As a preferred embodiment of the panel inspection device, the second driving member is spaced apart from the panel to be peeled.

[0011] As a preferred embodiment of the panel inspection device, the support base has a placement groove, the panel to be peeled is placed in the placement groove, and part of the panel to be peeled is exposed at the opening of the placement groove.

[0012] As a preferred embodiment of the panel testing device, the bottom of the placement groove is provided with multiple adsorption holes, which are connected to an external negative pressure device.

[0013] As a preferred embodiment of the panel inspection device, the panel inspection device further includes a rotary drive component, and the support base is disposed on the rotary drive component.

[0014] As a preferred embodiment of the panel inspection device, the peeling assembly includes a fourth driving member and two clamping blocks spaced apart at the driving end of the fourth driving member. The fourth driving member is tractively connected to the two clamping blocks to drive the two clamping blocks to move closer or further apart from each other.

[0015] As a preferred embodiment of the panel detection device, the peeling assembly further includes a second elastic element and a clamping block. One of the two clamping blocks is connected to the clamping block via the second elastic element. The clamping block is located between the two clamping blocks, and the second elastic element has a tendency to drive the clamping block towards the other clamping block; and / or,

[0016] The panel detection device also includes a collection box, which is spaced apart on the side of the support base away from the film-forming mechanism, and the peeling mechanism can place the release film in the collection box.

[0017] The beneficial effects of this utility model are as follows: By using a film-lifting mechanism to lift the edge of the release film on the panel to be peeled, the convenience of the peeling mechanism in grasping the release film is improved. The first driving component drives the peeling component and its gripping edge-lifting part to move, so as to realize the separation of the release film from the panel to be peeled. This saves time and effort, and the automatic film peeling production efficiency is high. Moreover, the first driving component moves stably, which can ensure the peeling stability of the release film and reduce the occurrence of breakage due to unstable pulling during the peeling process. The detection mechanism performs automated glue detection on the surface of the panel to be peeled after the film is peeled, and the detection accuracy is high. Attached Figure Description

[0029] 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.

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figures 2 to 5 As shown, the panel detection device of this utility model embodiment includes a support base 1, a film lifting mechanism 2, a peeling mechanism 3, and a detection mechanism 4. The support base 1 is used to support the panel 100 to be peeled; the film lifting mechanism 2 is used to lift the edge of the release film 200 on the panel 100 to be peeled, so that the release film 200 is partially lifted to form a raised edge portion 201; the peeling mechanism 3 is disposed above the support base 1, and the peeling mechanism 3 includes a first driving member 31 and a peeling component 32. The peeling component 32 is used to grasp the raised edge portion 201. The first driving member 31 is connected to the peeling component 32 to drive the peeling component 32 and the raised edge portion 201 to move away from the film lifting mechanism 2, so that the release film 200 is separated from the panel 100 to be peeled; the detection mechanism 4 is disposed at intervals on one side of the peeling mechanism 3 along the horizontal direction (the horizontal direction is the X direction in the figure), and the detection mechanism 4 is used to detect the glue on the surface of the panel 100 after the film is peeled off.

[0032] Understandably, by using the film lifting mechanism 2 to lift the edge of the release film 200 on the film-to-be-peeled panel 100, the convenience of the peeling mechanism 3 in grasping the release film 200 is improved. The first driving component 31 drives the peeling component 32 and its gripping edge lifting part 201 to move, so as to realize the separation of the release film 200 from the film-to-be-peeled panel 100. This saves time and effort, and the automatic film peeling production efficiency is high. Moreover, the first driving component 31 moves stably, which can ensure the peeling stability of the release film 200 and reduce the occurrence of breakage due to unstable pulling during the peeling process. The detection mechanism 4 performs automated glue detection on the surface of the film-to-be-peeled panel 100 after peeling, and the detection accuracy is high.

[0033] Optionally, such as Figure 2 As shown, the film-removing mechanism 2 includes a mounting frame 21. The detection mechanism 4 can employ CCD cameras. Multiple CCD cameras are mounted on the mounting frame 21, with all CCD cameras facing the panel. They take pictures of the panel surface after the film is removed to obtain detection information, thereby determining the residual adhesive on the panel. Alternatively, the panel detection device can also include a display, electrically connected to the CCD cameras, to display the detection information acquired by the CCD cameras, facilitating observation and timely feedback by operators.

[0034] Furthermore, such as Figure 2 and Figure 3 As shown, the film-lifting mechanism 2 also includes a second driving member 22 and a film-lifting assembly 23. The mounting frame 21 is disposed on one side of the support base 1 along the horizontal direction. The second driving member 22 is disposed on the mounting frame 21 and is located above the support base 1. The second driving member 22 is used to drive the film-lifting assembly 23 to move in the vertical direction (the vertical direction is the Y direction shown in the figure). The film-lifting assembly 23 can abut against the film panel 100 to be peeled. The film-lifting assembly 23 includes a third driving member 231 and a film-lifting member 232. The third driving member 231 is disposed at the driving end of the second driving member 22. The third driving member 231 and the film-lifting member 232 are connected in a transmission manner. The film-lifting member 232 can separate part of the release film 200 from the film panel 100 to be peeled to form a raised edge 201 by moving in the first direction. The first direction (in this embodiment, the first direction can be the X direction) is set at an angle to the vertical direction.

[0035] After the operator places the panel 100 to be peeled on the support base 1, the second drive component 22 drives the film lifting component 23 to move downward in the vertical direction so that the film lifting component 23 abuts against the panel 100 to be peeled. At this time, the second drive component 22 remains stationary, and the third drive component 231 drives the film lifting component 232 to move toward the release film 200 until the film lifting component 232 presses against the release film 200 and causes part of the release film 200 to lift up. The structure is simple and the operation is convenient, which improves the ease of peeling the release film 200 and avoids the situation where the release film 200 is difficult to pull up due to the glue sticking to the panel.

[0036] Furthermore, such as Figure 3 As shown, the film-lifting component 232 includes a film-lifting blade with an inclined surface 2321. The inclined surface 2321 slopes downwards from one end adjacent to the second driving member 22 toward the end away from the second driving member 22. The film-lifting blade can be inserted between the release film 200 and the film panel 100 to be peeled, allowing part of the release film 200 to separate from the film panel 100 along the inclined surface 2321. The inclined surface 2321 facilitates the insertion of the film-lifting blade between the release film 200 and the film panel 100 to lift the release film 200, improving the ease of film removal. Of course, in other embodiments, the film-lifting component 232 can also be used to directly push the edge of the release film 200 to lift the release film 200. Preferably, the cutting position of the film-lifting blade is at the corner of the release film 200, where the adhesive force is smaller, facilitating film removal. It should be noted that the top of the film-lifting knife also has a horizontally set top surface, so that the lifting edge 201 can be lifted up along the inclined surface 2321 and protrude from the top surface to be grasped.

[0037] Preferably, the film-lifting mechanism 2 further includes a mounting base 233 and a first elastic element 234. A third driving element 231 is disposed on the bottom side of the mounting base 233, and the first elastic element 234 is disposed on the top side of the mounting base 233. The side of the first elastic element 234 away from the mounting base 233 is connected to the driving end of the second driving element 22. The first elastic element 234 effectively buffers the second driving element 22 when it drives the peeling assembly 32 to contact the film panel 100 to be peeled, reducing the possibility of damage to the film panel 100 caused by rigid contact between the film-lifting assembly 23 and the film panel 100, thus improving the protection of the film panel 100.

[0038] Furthermore, the second driving member 22 is spaced apart from the film panel 100 to be peeled, that is, the second driving member 22 drives the film lifting assembly 23 to move downward in the vertical direction until the film lifting blade of the film lifting assembly 23 abuts against the film panel 100 to be peeled. At this time, the second driving member 22 is spaced apart from the film panel 100 to be peeled, reducing the contact area between the film lifting assembly 23 and the film panel 100 to be peeled, thereby reducing the possibility of wear due to rigid contact between the film lifting assembly 23 and the film panel 100 to be peeled, and effectively improving the protection of the film panel 100 to be peeled.

[0039] In some embodiments, such as Figure 4As shown, the support base 1 has a placement groove 11. The film panel 100 to be peeled is placed in the placement groove 11, with a portion of the film panel 100 protruding from the groove opening. The placement groove 11 ensures the film panel 100 is properly inserted, improving the installation accuracy of the film panel 100 on the support base 1, thereby guaranteeing the film lifting accuracy of the film lifting mechanism 2 and the peeling accuracy of the peeling mechanism 3. By utilizing the groove wall of the placement groove 11 to restrict the film panel 100, the peeling quality is prevented from being affected by the movement of the film panel 100 along with the release film 200 when the peeling mechanism 3 pulls the release film 200, effectively ensuring the stability of the placement position of the film panel 100.

[0040] Furthermore, the bottom of the placement groove 11 is provided with multiple adsorption holes 12, which are connected to an external negative pressure device. After the panel 100 to be peeled is placed in the installation groove, the external negative pressure device is activated to create a negative pressure that adsorbs the panel 100 through the adsorption holes 12, thereby increasing the connection strength between the panel 100 and the support base 1 and reducing the possibility of the panel 100 being pulled by the peeling mechanism 3, thus ensuring the placement stability of the panel 100. In addition, to improve the safety of the panel 100, a buffer adhesive can be provided at the bottom of the placement groove 11 to avoid rigid contact between the panel 100 and the bottom of the placement groove 11, thus ensuring the structural safety of the panel 100.

[0041] Furthermore, such as Figure 2 As shown, the panel detection device also includes a rotary drive 5, with a support base 1 mounted on the rotary drive 5. The rotary drive 5 allows the support base 1 and the panel 100 to be peeled to rotate, switching between different starting points of the panel 100 for edge lifting and peeling. For example, the rotary drive 5 is a motor. During the process of the first drive 31 driving the peeling assembly 32 to move away from the film lifting mechanism 2 to separate the release film 200, if the release film 200 breaks, the motor drives the support base 1 to rotate 90° or 180° so that the other corner of the panel 100 is adjacent to the film lifting mechanism 2, thereby performing a secondary edge lifting and peeling.

[0042] In other embodiments, the peeling assembly 32 includes a fourth driving member 321 and two clamping blocks 322 spaced apart at the driving end of the fourth driving member 321. The fourth driving member 321 is tractively connected to the two clamping blocks 322 to drive the two clamping blocks 322 to move closer or further apart from each other. After the film lifting mechanism 2 lifts a portion of the release film 200, the first driving member 31 drives the peeling assembly 32 to move toward the lifted edge 201 until the lifted edge 201 is located between the two clamping blocks 322. The fourth driving member 321 drives the two clamping blocks 322 to move closer together to clamp the lifted edge 201. At this time, the fourth driving member 321 maintains the state of driving the clamping blocks 322 to clamp the lifted edge 201. The first driving member 31 drives the peeling assembly 32 and the clamped lifted edge 201 to move away from the lifting mechanism to gradually peel the release film 200 from the film panel 100 to be peeled.

[0043] In addition, the first driving member 31 may include a first sub-driving member 312 moving in the vertical direction and a second sub-driving member 311 moving in the first direction. The second sub-driving member 311 is disposed on the mounting bracket 21, and the first sub-driving member 312 is disposed at the driving end of the second sub-driving member 311. That is, after the peeling component 32 clamps the starting edge 201, the second sub-driving member 311 drives the first sub-driving member 312 and the peeling component 32 to move in the first direction. At the same time, the first sub-driving member 312 drives the peeling component 32 to move upward in the vertical direction. This can prevent the release film 200 adjacent to the starting edge 201 from drooping and sticking to the release film 200 at the rear end after peeling a certain length, thus preventing it from being easily torn. This effectively improves the peeling stability of the release film 200.

[0044] Furthermore, the peeling assembly 32 also includes a second elastic member 323 and a clamping block 324. One of the two clamping blocks 322 is connected to the clamping block 324 via the second elastic member 323. The clamping block 324 is located between the two clamping blocks 322. The second elastic member 323 has a tendency to drive the clamping block 324 toward the other clamping block 322.

[0045] Taking two clamping blocks 322 as an example, namely the first clamping block 3221 and the second clamping block 3222, abutment blocks 324 are provided at intervals on the side of the first clamping block 3221 adjacent to the second clamping block 3222. The abutment blocks 324 are connected to the first clamping block 3221 through a second elastic member 323. The release film 200 is clamped between the second clamping block 3222 and the abutment blocks 324. The second elastic member 323 has a tendency to drive the abutment blocks 324 to press against the release film 200. By setting the second elastic member 323 and the abutment blocks 324, the situation where the release film 200 is too thin to be clamped securely can be avoided, the production tolerance of the clamping surface of the second clamping block 3222 can be reduced, and the clamping strength of the release assembly 32 can be improved.

[0046] Furthermore, the panel inspection device also includes collection boxes, which are spaced apart on the side of the support base 1 away from the film-lifting mechanism 2. The peeling mechanism 3 can place the release film 200 in the collection box. For example, the fourth drive member 321 drives two clamping blocks 322 to clamp the lifting edge until the first drive member 31 moves to completely peel off the release film 200, and moves the peeling assembly 32 and the release film 200 above the collection box. The first drive member 31 remains stationary, and the fourth drive member 321 drives the two clamping blocks 322 to move away from each other to release the release film 200. The release film 200 falls into the collection box due to its own weight. The collection box allows for the unified collection of the peeled release film 200, reducing the possibility of the peeled release film 200 being placed haphazardly, thus providing a good working environment for the panel inspection device.

[0047] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
