[0002] Reflective sheet is an important component of display devices, mainly used to improve the efficiency of light use of the backlight source of display devices (such as TV sets). In the production process of reflective sheets, defect detection (such as scratches on the surface of reflective sheets) is an important link to ensure the performance of display devices such as TV sets. That is, visual cameras are used to identify defects such as scratches on the surface of reflective sheets, so as to separate defective reflective sheets as problematic reflective sheets from non-defective reflective sheets.

[0003] The upper reflective sheet before detection and the lower reflective sheet after detection both need to be transferred by a transfer device, which usually uses negative pressure adsorption to grab the reflective sheet. The tray on the upper sheet station stores multiple reflective sheets arranged in layers. Since the reflective sheets are thin and have many dense holes, when the reflective sheets are adsorbed, they will be adsorbed to the reflective sheet on the lower side through the holes on the outermost reflective sheet, that is, multiple reflective sheets can be adsorbed at one time.

[0004] Therefore, how to avoid the situation of adsorbing multiple sheets at one time and prevent the sheets from sticking during adsorption is a technical problem that technicians in this field need to solve at present. Utility Model Content

[0039] The core of the utility model is to provide a film transfer device to avoid the situation of adsorbing multiple films at one time and prevent the film from sticking during adsorption;

[0040] Another core of the utility model is to provide a membrane detection device having the above-mentioned membrane transfer device.

[0041] The film inspection equipment usually includes an upper film transmission line, an inspection line, a lower film device, etc. The flow of the film between the various devices requires the participation of a film transfer device. For example, the upper film transmission line requires the participation of a film transfer device to transfer the films in the tray to the upper film transmission line one by one through the film transfer device; the lower film device also requires the participation of a film transfer device to transfer each qualified product after the inspection to the tray in sequence through the film transfer device; in addition, a film transfer device is also required upstream of the lower film device to transfer the film after the inspection to the lower film device, and use the lower film device to separate qualified products and defective products.

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] like Figure 1 and Figure 2As shown, an embodiment of the utility model discloses a membrane transfer device, which includes a plurality of suction cup assemblies 200, wherein the number and positions of the suction cup assemblies 200 can be arranged according to the size of the membrane. If the size of the membrane is relatively large, the number of the suction cup assemblies 200 can be increased; if the size of the membrane is relatively small, the number of the suction cup assemblies 200 can be reduced accordingly.

[0044] like Figure 3 As shown, at least one suction cup assembly 200 is a shaking suction cup assembly, and the shaking suction cup assembly includes a shaking drive mechanism 201 and a suction cup module arranged on the output end of the shaking drive mechanism 201. The suction cup module can generate a negative pressure adsorption force under the action of the negative pressure device to achieve adsorption of the diaphragm. It should be noted that the structure and principle of the suction cup module can be the same as those in the prior art, and will not be repeated herein. Since there are relatively dense holes distributed on the diaphragm, in order to achieve adsorption of the diaphragm, the suction cup module adopts a microporous integrated suction cup module.

[0045] The shaking drive mechanism 201 is used to drive the suction cup module to move between the upper limit position and the lower limit position. It should be noted that the shaking drive mechanism 201 can be a cylinder, and the suction cup module is connected to the piston cylinder of the shaking drive mechanism 201. The suction cup module moves between the upper limit position and the lower limit position through the extension and retraction of the piston cylinder.

[0046] The suction cup module has a film taking position, and the film taking position is located between the upper limit position and the lower limit position. Before the film transfer device adsorbs the film, the shaking drive mechanism 201 needs to move the suction cup module to the film taking position. At this time, the suction cup module of the shaking suction cup assembly and the suction cup modules of other suction cup assemblies 200 are at the same height position, that is, the adsorption surface of the shaking suction cup assembly and the adsorption surface of the other suction cup assembly 200 are located on the same plane, so that the shaking suction cup assembly and the other suction cup assemblies 200 can adsorb the film at the same time.

[0047] The film transfer device provided by the utility model, after the film is adsorbed, the shaking driving mechanism 201 of the shaking suction cup assembly drives the suction cup module on the output end to move up and down to produce a shaking effect. If the film transfer device adsorbs multiple films at the same time, because the adsorption force of the film on the lower side is smaller than the adsorption force of the film on the uppermost side, the other films can fall due to insufficient adsorption force under the action of the shaking of the shaking suction cup assembly, thereby preventing the film from sticking during adsorption.

[0048] It should be noted that, in order to facilitate the distinction between the shaking suction cup assembly and the suction cup assembly 200 without the shaking function, in this embodiment, the other suction cup assemblies 200 except the shaking suction cup assembly are defined as ordinary suction cup assemblies. The difference between the ordinary suction cup assembly and the shaking suction cup assembly is that the ordinary suction cup assembly does not have a shaking drive mechanism 201.

[0049] The suction cup module of each suction cup assembly 200 (i.e., the suction cup module of the common suction cup assembly and the suction cup module of the shaking suction cup assembly) includes a suction cup mounting seat 203 and a negative pressure suction cup 204, and the negative pressure suction cup 204 is connected to the suction cup mounting seat 203 via a buffer elastic member 205. The suction cup mounting seat 203 of the shaking suction cup assembly can be mounted at the output end of the shaking driving mechanism 201, while the suction cup mounting seat 203 of the common suction cup assembly can be directly mounted on the suction cup mounting bracket 202.

[0050] In this embodiment, the negative pressure suction cup 204 is connected to the suction cup mounting seat 203 through the buffer elastic member 205, so that when the diaphragm transfer device moves downward to adsorb the diaphragm, when the negative pressure suction cup 204 contacts the diaphragm, even if the diaphragm transfer device continues to move downward for a certain displacement, the compression amount of the buffer elastic member 205 can prevent the diaphragm from being crushed by the negative pressure suction cup 204.

[0051] In order to further improve the effect of the release sheet, Figure 1 As shown, in this embodiment, the film transfer device may further include an anti-adhesive sheet mechanism 300 disposed on one side of the shaking suction cup assembly. The height of the lowest end of the anti-adhesive sheet mechanism 300 may be designed to be higher than the lowest end of the suction cup module when it is in the film taking position, and lower than the lowest end of the suction cup module when it is in the upper limit position, that is, the lowest end of the anti-adhesive sheet mechanism 300 is located above the adsorption surface of the suction cup assembly 200, so that during the film transfer device adsorbing the film, the suction cup assembly 200 first contacts the film.

[0052] Specifically, after the film transfer device completes the adsorption of the film, the shaking drive mechanism 201 of the shaking suction cup assembly drives the suction cup module on the output end to move up and down to produce a shaking effect. Since the height of the lowest end of the anti-adhesive sheet mechanism 300 is lower than the height of the lowest end of the suction cup module when it is in the upper limit position, the distance difference between the two will be offset during the film being driven to move upward, so that the film contacts the lowest end of the anti-adhesive sheet mechanism 300, producing the effect of beating the film. In this embodiment, the number of times the anti-adhesive sheet mechanism 300 beats the film can be set by the number of times the suction cup module moves up and down. For example, the number of times the suction cup module moves up and down can be designed to be 3 times. According to experimental verification, the effect of shaking off the film that is adsorbed more can be met, and the problem of the film being stuck and lifted can be further prevented.

[0053] Furthermore, the installation position of the anti-adhesive sheet mechanism 300 and the installation position of the corresponding shaking suction cup assembly are within a preset range. That is, each shaking suction cup assembly needs to be equipped with at least one anti-adhesive sheet mechanism 300 next to it. In this embodiment, the difference between the height of the lower end of the anti-adhesive sheet mechanism 300 and the height of the lower end of the suction cup module when it is in the sheet-taking position can be selected to be 5mm-15mm, for example, 10mm; the preset range of 20mm-30mm can be selected. It should be noted that the above-mentioned size range is only for example, and those skilled in the art can set the above-mentioned size range according to the actual application scenario, and the above-mentioned example should not affect the scope of protection of this application.

[0054] like Figure 4 As shown, the bottom end of the anti-adhesive sheet mechanism 300 has a protective portion 302, that is, the anti-adhesive sheet mechanism 300 may include an anti-adhesive sheet mounting seat 301, and the protective portion 302 is arranged at the bottom end of the anti-adhesive sheet mounting seat 301. The protective portion 302 can be made of a material with a buffering effect, such as polyurethane. When the shaking suction cup assembly outputs a shaking action, the protective portion 302 with a buffering effect contacts the diaphragm to prevent scratching the diaphragm.

[0055] In a specific embodiment of the utility model, there are multiple shaking suction cup assemblies, and they correspond to the corner areas of the adsorbed film. Taking the shape of the film as a rectangle as an example, at least the suction cup assemblies used to adsorb the four corner areas of the film are designed as shaking suction cup assemblies with a shaking function. It should be noted that the suction cup assemblies of the film transfer device can all be shaking suction cup assemblies, that is, the suction cup assemblies are only arranged in the four corner areas, and the number of suction cup assemblies of the film transfer device can also be designed to be greater than 4, that is, in addition to the shaking suction cup assemblies at the four corner positions, a number of ordinary suction cup assemblies can also be added.

[0056] In order to improve the shaking effect, in this embodiment, at least the two shaking sucker assemblies that are farthest apart move in opposite directions when shaking the film. For example, in a case where there are four shaking sucker assemblies and the four shaking sucker assemblies are arranged in a rectangle, the two shaking sucker assemblies that are farthest apart are two shaking sucker assemblies on the diagonal line, that is, in this embodiment, the two shaking sucker assemblies on the diagonal line move in opposite directions when shaking the film, for example, when one of the shaking sucker assemblies outputs an upward movement, the other outputs a downward movement. In this way, the position of the film on the diagonal line can be increased to have a larger movement amplitude, so that a greater shaking force is generated on the film, further improving the effect of the anti-adhesive sheet.

[0057] In a specific embodiment of the present invention, the film transfer device may further include an anti-collision component 400, such as Figure 5 and Figure 6As shown, the anti-collision assembly 400 includes a guide rail device 402 , an anti-collision block 405 , a resetting elastic member 406 , a position sensor 407 and a position sensing sheet 404 .

[0058] The guide rail device 402 can be arranged on the anti-collision component mounting plate 401 of the anti-collision component 400. Generally, the guide rail device 402 can extend in the vertical direction. The anti-collision block 405 is slidably matched with the guide rail device 402. Specifically, the anti-collision block 405 can be arranged on the guide rail slider 403, and the guide rail slider 403 is slidably matched with the guide rail device 402.

[0059] When the anti-collision block 405 is in the initial position, the height of the lower surface of the anti-collision block 405 is higher than the height of the lowest end of the suction cup module when it is in the film-taking position. The initial position refers to the position of the anti-collision block 405 when it is not collided in a natural state. When the film transfer device is in the working condition of adsorbing the film, the suction cup module first contacts the object below the film transfer device, and the object below may be a film or an obstacle. If it continues to descend, the anti-collision block 405 will contact the object below, and the anti-collision block 405 will slide along the guide rail device 402.

[0060] One of the position sensor 407 and the position sensing sheet 404 moves synchronously with the anti-collision block 405, and the other is stationary relative to the guide rail device 402. In this embodiment, the position sensor 407 is fixed to a fixed component such as the anti-collision component mounting plate 401 or the guide rail device 402, and the position sensing sheet 404 is fixed to the anti-collision block 405 or the guide rail slider 403, and moves up and down with the anti-collision block 405.

[0061] When the position sensor 407 and the position sensing sheet 404 correspond to each other, a sensing signal is generated. When the position sensor 407 and the position sensing sheet 404 correspond to each other, the height of the lower surface of the anti-collision block 405 is higher than the height of the lowest end of the suction cup module when it is in the film taking position, and lower than the height of the lowest end of the suction cup module when it is compressed to the limit position. With such an arrangement, the position sensor 407 and the position sensing sheet 404 can generate a sensing signal before the suction cup module is compressed to the limit position. The sensing signal can be used to remind the operator that there is a fault and it is necessary to stop the film transfer device from continuing to descend to avoid the suction cup module from hard collision with the object below.

[0062] Furthermore, the diaphragm transfer device may also include a reset elastic member 406, one end of which is connected to the guide rail device 402, and the other end is connected to the anti-collision block 405. When the diaphragm transfer device is in the working condition of adsorbing the diaphragm, the suction cup module first contacts the object below the diaphragm transfer device. If it continues to descend, the anti-collision block 405 will contact the object below, and the anti-collision block 405 will slide along the guide rail device 402, and the reset elastic member 406 will be stretched and tensioned. Under the action of the reset elastic member 406, it can ensure that the anti-collision block 405 is always in contact with the object below, avoiding the problem of misjudgment caused by the anti-collision block 405 bouncing due to collision when the anti-collision block 405 just contacts the object below.

[0063] In order to ensure that the suction cup module can automatically stop descending before it collides hard with the object below, in this embodiment, the membrane transfer device may also include a controller and a lifting drive device that drives the overall lifting and lowering of each suction cup assembly. When the position sensor 407 and the position sensing sheet 404 generate a sensing signal, the controller is used to control the lifting drive device to stop to avoid a hard collision between the suction cup module and the object below.

[0064] In this embodiment, the membrane transfer device may further include a membrane sensor 500, which can sense whether there is a membrane below the membrane transfer device, so that only when there is a membrane below, the lifting drive device is controlled to descend to grab the membrane.

[0065] Furthermore, the film transfer device may also include a mounting frame 100, and the suction cup assembly 200, the anti-adhesive sheet mechanism 300 and the anti-collision assembly 400 may all be mounted on the mounting frame 100. Specifically, the suction cup mounting seat 203 of the shaking suction cup assembly is mounted on the output end of the shaking drive mechanism 201, and the shaking drive mechanism 201 is mounted on the suction cup mounting bracket 202, and the suction cup mounting bracket 202 is mounted on the mounting frame 100. The suction cup mounting seat 203 of the ordinary suction cup assembly can be directly mounted on the suction cup mounting bracket 202, and the suction cup mounting bracket 202 is mounted on the mounting frame 100. It should be noted that the solenoid valve assembly 600 of the lifting drive device can also be set on the mounting frame 100.

[0066] In order to ensure that the adsorption surfaces of each suction cup assembly 200 are at the same height, the suction cup mounting bracket 202 can be adjusted in height on the mounting frame 100, and the height adjustment of the suction cup assembly 200 can also be achieved by adjusting the height between different parts of the suction cup mounting bracket 202.

[0067] The anti-sticking sheet mechanism 300 can be installed on the mounting frame 100 through its anti-sticking sheet mounting seat 301. The anti-sticking sheet mounting seat 301 can be fixed to the mounting frame 100 by fasteners through the strip holes opened thereon. After the fasteners are loosened, the height of the anti-sticking sheet mounting seat 301 can be adjusted up and down using the strip holes, and then the height of the protective part 302 can be adjusted. After the height adjustment is completed, the fasteners can be locked.

[0068] The anti-collision component 400 can be installed on the mounting frame 100 through its anti-collision component mounting plate 401. The anti-collision component mounting plate 401 can be fixed to the mounting frame 100 by fasteners through the strip holes opened thereon. After the fasteners are loosened, the height of the anti-collision component mounting plate 401 can be adjusted up and down using the strip holes, and then the height of the anti-collision block 405 can be adjusted. After the height adjustment is completed, the fasteners can be locked.

[0069] like Figure 1 As shown, the lifting output end of the lifting drive device can act on the installation frame 100 to drive the installation frame 100 and the suction cup assembly 200, the anti-adhesive sheet mechanism 300 and the anti-collision assembly 400 thereon to rise and fall synchronously.

[0070] In this embodiment, the position of the suction cup assembly 200 on the mounting frame 100 is adjustable, so as to achieve the effect of being compatible with diaphragms of different sizes. Specifically, an adjustment track is formed on the mounting frame 100, and the suction cup mounting bracket 202 can be slidably matched with the adjustment track on the mounting frame 100, and the suction cup mounting bracket 202 and the adjustment track are locked by a locking member. In this embodiment, the locking member used to lock the suction cup mounting bracket 202 and the adjustment track can be a locking member with a butterfly handle 206, so that locking can be achieved by rotating the locking member.

[0071] Specifically, the locking method of the locking member can be that the locking member has a screw portion, a slider is provided at one end of the screw portion, and a butterfly handle 206 can be provided at the other end. The slider is slidably matched with the adjustment track, and the slider is also threadedly matched with the screw portion. The locking member is rotatably set on the suction cup mounting bracket 202, and can only rotate along the suction cup mounting bracket 202, and cannot move up and down relative to the suction cup mounting bracket 202. After the locking member and the slider are loosened, the slider can slide along the adjustment track to change its position. After adjusting to a suitable position, the locking member is rotated so that the slider moves downward along the screw portion until it is pressed against the track groove wall of the adjustment track, and the suction cup assembly 200 is restricted from continuing to move by friction. When the position of the suction cup assembly 200 needs to be adjusted, it is only necessary to loosen the contact between the slider and the adjustment track by rotating the locking member.

[0072] The mounting frame 100 can be formed by splicing a plurality of first adjustment beams 101 and a plurality of second adjustment beams 102, wherein the extension directions of the first adjustment beam 101 and the second adjustment beam 102 can be designed to be perpendicular to each other. The first adjustment beam 101 and the second adjustment beam 102 are connected at the splicing point by an adjustment assembly 103. In this embodiment, the adjustment assembly 103 may include an adjustment block and an adjustment bolt, wherein the adjustment block may be arranged on one of the first adjustment beam 101 and the second adjustment beam 102. For ease of understanding, the adjustment block is arranged on the first adjustment beam 101 as an example for introduction. The adjustment block is formed with a space for the second adjustment beam 102 to pass through, and the second adjustment beam 102 can be inserted into the space, and the fixed position can be adjusted along the extension direction of the second adjustment beam 102. After adjusting the fixed position, the second adjustment beam 102 and the adjustment block can be locked by the adjustment bolt, and the suction cup assembly 200 is installed on the first adjustment beam 101.
