Abstract
Description
Technical Field
[0001] The present application relates to the technical field of product film lamination, and in particular to a positioning jig and a laminating device. Background Art
[0002] During the production and processing of electronic products, it is usually necessary to apply a film to the workpiece to protect it, or to attach structural parts that meet design requirements to the predetermined position of the workpiece. When applying the film, the workpiece needs to be positioned first, and then the film is attached to the workpiece. However, when applying the film to some thin-sheet workpieces, if the force applied to position the workpiece is too large, the workpiece will be damaged. If the force applied to position the workpiece is too small, the workpiece will shift during the application of the film, resulting in unqualified film application accuracy. In addition, when applying the film using the traditional method, the film is directly placed on the workpiece, which easily causes bubbles to form between the film and the workpiece.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0049] The embodiments of the present application will be further described below with reference to the accompanying drawings.
[0050] Please refer to Figures 1 to 3 , an embodiment of the present application provides a positioning jig 100 for positioning a workpiece 500. The workpiece 500 can be a plate-like or sheet-like structure, such as a steel sheet, a glass panel, etc. The positioning jig 100 includes a support plate 10, a vacuum plate 20, a carrier plate 30, and an anti-slip member 40.
[0051] The support plate 10 can be a plate-like structure to provide stable support for the vacuum plate 20 and facilitate connection with an external structure. The external structure can be a workbench, etc. In this embodiment, the external driving device can be the first driving assembly 300 described below (please refer to Figure 4 ).
[0052] The vacuum plate 20 is connected to the support plate 10. The vacuum plate 20 is provided with an air extraction channel 21. The vacuum plate 20 can be a plate-like structure to provide stable support for the carrier plate 30.
[0053] The carrier plate 30 is connected to the side of the vacuum plate 20 facing away from the support plate 10. On the side of the carrier plate 30 facing away from the vacuum plate 20, an adsorption area 31 for adsorbing the workpiece 500 is provided. A plurality of first vacuum holes 32 penetrating the carrier plate 30 are arranged in the adsorption area 31, and the plurality of first vacuum holes 32 are all communicated with the air extraction channel 21. A receiving groove 33 is formed on the side of the carrier plate 30 facing away from the vacuum plate 20, and the receiving groove 33 is arranged in the middle of the adsorption area 31 and is communicated with the plurality of first vacuum holes 32 at the bottom of the groove. The carrier plate 30 can be in a plate-like structure to provide a stable supporting effect on the workpiece 500. The shape of the adsorption area 31 is adapted to the shape of the workpiece 500. For example, if the shape of the workpiece 500 is rectangular, the shape of the adsorption area 31 is a corresponding rectangle; if the shape of the workpiece 500 is circular, the shape of the adsorption area 31 is a corresponding circle. In this way, the workpiece 500 can be stably adsorbed. It can be understood that the adsorption area 31 can also be other structures as long as it is adapted to the workpiece 500, and no limitation is made here. In this embodiment, the area of the adsorption area 31 is the same as the area of the workpiece 500, so that when the workpiece 500 is placed on the carrier plate 30, the adsorption area 31 can adsorb the overall structure of the workpiece 500. It can be understood that the area of the receiving groove 33 is smaller than the area of the adsorption area 31, and the shape of the receiving groove 33 is adapted to the shape of the workpiece 500.
[0054] The anti-slip member 40 is arranged in the receiving groove 33. The side of the anti-slip member 40 facing away from the bottom of the receiving groove 33 is flush with the side of the carrier plate 30 facing away from the vacuum plate 20. A plurality of second vacuum holes 41 penetrating the anti-slip member 40 are formed in the anti-slip member 40, and the plurality of second vacuum holes 41 are in one-to-one correspondence and communication with the plurality of first vacuum holes 32 at the bottom of the receiving groove 33. It can be understood that the area of the anti-slip member 40 is smaller than the area of the adsorption area 31, that is, smaller than the area of the workpiece 500. In this way, when the workpiece 500 is placed on the adsorption area 31, the workpiece 500 is supported by the carrier plate 30 and the anti-slip member 40 together.
[0055] Among them, the vacuum plate 20 is used to be connected to an external air extraction device (not shown in the figure) and extract air from the plurality of first vacuum holes 32 and the plurality of second vacuum holes 41 through the air extraction channel 21, so as to adsorb and position the workpiece 500 located in the adsorption area 31.
[0056] It can be understood that when the workpiece 500 is placed on the adsorption area 31, it can be placed through an external feeding device (not shown in the figure). The external feeding device can be a manipulator or the like to improve the accuracy of placing the workpiece 500 on the adsorption area 31 and further improve the accuracy during positioning.
[0057] The positioning fixture 100 provided by the embodiment of the present application can carry the workpiece 500 through the carrier plate 30. After the workpiece 500 is placed in the adsorption area 31 on the carrier plate 30, an external air extraction device extracts air from the first vacuum holes 32 and the second vacuum holes 41 in the adsorption area 31 through the air extraction channels 21 of the vacuum plate 20, thereby adsorbing the workpiece 500 to the adsorption area 31 and completing the positioning of the workpiece 500. An anti-slip member 40 is arranged in the adsorption area 31, which can increase the friction between the workpiece 500 and the positioning fixture 100, prevent the workpiece 500 from shifting during film pasting, and improve the stability of positioning the workpiece 500. When the workpiece 500 is placed in the adsorption area 31, the workpiece 500 is jointly supported by the carrier plate 30 and the anti-slip member 40, which can not only ensure the stability of supporting the workpiece 500, but also prevent the workpiece 500 from sliding relative to the carrier plate 30, and the positioning stability is high.
[0058] In some embodiments, please refer to Figure 1 and Figure 2 , a plurality of air extraction channels 21 are provided in the vacuum plate 20. A plurality of adsorption areas 31 and accommodation grooves 33 are provided on the side of the carrier plate 30 facing away from the vacuum plate 20. The plurality of adsorption areas 31 are arranged at intervals, and the plurality of accommodation grooves 33 are arranged in one-to-one correspondence with the plurality of adsorption areas 31. A plurality of anti-slip members 40 are provided, and each anti-slip member 40 is correspondingly arranged in one accommodation groove 33. Among them, each air extraction channel 21 is correspondingly communicated with a plurality of first vacuum holes 32 and a plurality of second vacuum holes 41 in one adsorption area 31. It can be understood that in some manufacturing processes, it is necessary to bond a plurality of workpieces 500 to a film member 600 (please refer to Figure 5 ). By providing a plurality of adsorption areas 31, a plurality of workpieces 500 can be correspondingly adsorbed. The number of adsorption areas 31 can be two, three, four, etc. The number and position of the adsorption areas 31 are consistent with the number and position of the workpieces 500 to be bonded, and specifically depend on actual requirements and are not limited herein. The number of air extraction channels 21 is consistent with the number of adsorption areas 31. Each air extraction channel 21 is correspondingly communicated with one adsorption area 31, and when connected to an external air extraction device, each air extraction channel 21 is connected to an independent external air extraction device. In this way, it is convenient to accurately detect the corresponding adsorption area 31 in case of poor adsorption and facilitate maintenance.
[0059] In some embodiments, please refer to Figure 2 and Figure 3, the carrier plate 30 is made of aluminum alloy material, and the anti-slip member 40 is made of silicone material. The hardness range of the anti-slip member 40 is 50HA - 70HA. The hardness of the anti-slip member 40 can be 50HA, 55HA, 60HA, 65HA, 70HA, etc. It can be understood that the hardness of the anti-slip member 40 can also be any value between 50HA - 70HA, which is not limited here. When the hardness of the anti-slip member 40 is less than 50HA, the anti-slip member 40 is too soft, resulting in insufficient support for the workpiece 500, causing the part of the workpiece 500 opposite to the anti-slip member 40 to sink and other parts to warp when adsorbing the workpiece 500 or fitting the film member 600 to the workpiece 500 (please refer to Figure 5 ), thereby leading to unstable positioning of the workpiece 500, or when fitting the film member 600, there are bubbles in the film member 600 that fits at the position of the workpiece 500 opposite to the anti-slip member 40. When the hardness of the anti-slip member 40 is greater than 70HA, the anti-slip member 40 is too hard, and the friction coefficient between the anti-slip member 40 and the workpiece 500 becomes smaller, resulting in unstable positioning of the workpiece 500, and the workpiece 500 is prone to displacement during the process of fitting the film member 600. The hardness of the anti-slip member 40 is set between 50HA - 70HA, which can not only provide sufficient support force for the workpiece 500, but also provide sufficient friction force to improve the stability when positioning the workpiece 500.
[0060] In some embodiments, please refer to Figure 2 and Figure 3 , the area of the anti-slip member 40 is greater than one-third of the area of the adsorption area 31 and less than two-thirds of the area of the adsorption area 31. When the area of the anti-slip member 40 is less than one-third of the area of the adsorption area 31, the anti-slip member 40 is too small, resulting in the anti-slip member 40 not being able to provide sufficient friction force for the workpiece 500, and the positioning is unstable. During the process of fitting the film member 600 (please refer to Figure 5 ), the workpiece 500 is prone to displacement. When the area of the anti-slip member 40 is greater than two-thirds of the area of the adsorption area 31, the anti-slip member 40 is too large, resulting in insufficient support for the workpiece 500 by the anti-slip member 40, causing the part of the workpiece 500 opposite to the anti-slip member 40 to sink and other parts to warp when adsorbing the workpiece 500 or fitting the film member 600 to the workpiece 500, thereby leading to unstable positioning of the workpiece 500, or when fitting the film member 600, there are bubbles in the film member 600 that fits at the position of the workpiece 500 opposite to the anti-slip member 40.
[0061] In some embodiments, please refer to Figure 2 and Figure 3, a plurality of first vacuum holes 32 are arranged in an array, and a plurality of second vacuum holes 41 are arranged in an array. The diameter of the first vacuum holes 32 is the same as that of the second vacuum holes 41, and the diameter range of both the first vacuum holes 32 and the second vacuum holes 41 is 0.5 mm - 1.5 mm; the distance between two adjacent first vacuum holes 32 is the same as the distance between two adjacent second vacuum holes 41, and the distance range between two adjacent first vacuum holes 32 and the distance between two adjacent second vacuum holes 41 are both 5 mm - 10 mm.
[0062] The diameter of the first vacuum holes 32 can be 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, 1.1 mm, 1.3 mm, 1.5 mm, and the diameter of the second vacuum holes 41 can be 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, 1.1 mm, 1.3 mm, 1.5 mm. It can be understood that the diameter of the first vacuum holes 32 and the second vacuum holes 41 can be any value between 0.5 mm - 1.5 mm, which is not limited here. When the diameter of the first vacuum holes 32 and the second vacuum holes 41 is less than 0.5 mm, the adsorption force on the workpiece 500 during vacuum pumping will be insufficient. When the diameter of the first vacuum holes 32 and the second vacuum holes 41 is greater than 1.5 mm, the aperture is too large, which will cause adsorption marks on the surface of the workpiece 500 and damage the surface of the workpiece 500.
[0063] The distance between two adjacent first vacuum holes 32 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm. It can be understood that the distance between two adjacent first vacuum holes 32 can be any value between 5 mm - 10 mm, which is not limited here. When the distance between two adjacent first vacuum holes 32 is less than 5 mm, the adsorption force on the workpiece 500 will be too large, damaging the surface of the workpiece 500. When the distance between two adjacent first vacuum holes 32 is greater than 10 mm, the adsorption force on the workpiece 500 during vacuum pumping will be insufficient, and the positioning of the workpiece 500 will be unstable.
[0064] The distance between two adjacent second vacuum holes 41 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm. It can be understood that the distance between two adjacent second vacuum holes 41 can be any value between 5 mm - 10 mm, which is not limited here. When the distance between two adjacent second vacuum holes 41 is less than 5 mm, the adsorption force on the workpiece 500 will be too large, damaging the surface of the workpiece 500. When the distance between two adjacent second vacuum holes 41 is greater than 10 mm, the adsorption force on the workpiece 500 during vacuum pumping will be insufficient, and the positioning of the workpiece 500 will be unstable.
[0065] In some embodiments, please refer to Figure 1 and Figure 2The positioning jig 100 also includes multiple leveling members 50, each connected to the support plate 10 and the vacuum plate 20. The leveling members 50 are evenly distributed along the inner circumference of the vacuum plate 20. The leveling members 50 are used to adjust the spacing between the support plate 10 and the vacuum plate 20, thereby adjusting the position of the vacuum plate 20 and the carrier plate 30 relative to the support plate 10. The number of leveling members 50 can be four, eight, or twelve, and can be, for example, hexagon socket head cap screws. Multiple leveling members 50 can be positioned near the sides of the vacuum plate 20. It is understood that when laminating the film 600 to the workpiece 500, to improve the lamination effect, the workpiece 500 must be horizontal. When the support plate 10 is fixedly connected to the external structure, this may cause the support plate 10 to be out of level, which in turn may cause the vacuum plate 20 and the carrier plate 30 to be out of level. During adjustment, the levelness of the carrier plate 30 is manually measured, and then the corresponding leveling members 50 are adjusted to ensure that the vacuum plate 20 and the carrier plate 30 are level. In this embodiment, in order to facilitate adjustment of the leveling member 50 , a plurality of through holes 34 corresponding to the leveling members 50 may be provided on the carrier plate 30 , and an operator may adjust the corresponding leveling member 50 through the through holes 34 .
[0066] In some embodiments, see Figure 2 and Figure 3 , the thickness range of the anti-slip part 40 along the direction perpendicular to the supporting plate 30 is 1.5mm-2.5mm. The thickness of the anti-slip part 40 can be 1.5mm, 1.7mm, 1.9mm, 2.0mm, 2.1mm, 2.3mm, 2.5mm, etc. It can be understood that the thickness of the anti-slip part 40 can also be any value between 1.5mm-2.5mm, which is not limited here. When the thickness of the anti-slip part 40 is less than 1.5mm, the anti-slip part 40 will be too thin and easily damaged, affecting the adsorption of the workpiece 500. When the thickness of the anti-slip part 40 is greater than 2.5mm, it will lead to insufficient support for the workpiece 500, resulting in the adsorption of the workpiece 500 or the lamination of the film part 600 to the workpiece 500 (see Figure 5 ), the portion of the workpiece 500 facing the anti-slip member 40 becomes concave, while other portions become warped, leading to unstable positioning of the workpiece 500. Alternatively, when laminating the film 600, bubbles may form in the film 600 where the workpiece 500 faces the anti-slip member 40. The anti-slip member 40 has a thickness ranging from 1.5 mm to 2.5 mm, which ensures its durability while preventing deformation of the workpiece 500.
[0067] The working process of the positioning fixture 100 provided in the embodiment of the present application is roughly as follows:
[0068] Place the workpiece 500 in the corresponding adsorption area 31, and then evacuate the adsorption area 31 through an external air extraction device. Negative pressure is generated at the positions of the multiple first vacuum holes 32 and the multiple second vacuum holes 41 in the adsorption area 31, thereby adsorbing the workpiece 500 and completing the positioning of the workpiece 500. When applying a film to the workpiece 500, the carrier plate 30 and the anti-slip member 40 can provide sufficient support for the workpiece 500, and the anti-slip member 40 can also provide sufficient friction for the workpiece 500 to prevent the workpiece 500 from shifting, with high positioning stability.
[0069] Please refer to Figure 1 、 Figure 4 and Figure 5 , the embodiment of the present application also provides a laminating device 1000 for laminating the workpiece 500 and the film member 600. The workpiece 500 can be in a plate-like or sheet-like structure, such as a steel sheet, a glass panel, etc., and the film member 600 can be a release film, etc. The laminating device 1000 includes the positioning fixture 100 and the laminating mechanism 200 in the above embodiment.
[0070] The laminating mechanism 200 includes a bracket 210, a material suction component 220 and a rolling component 230. The material suction component 220 is connected to the bracket 210. The material suction component 220 is used to adsorb the film member 600 and laminate the film member 600 on the workpiece 500 adsorbed in the adsorption area 31 of the positioning fixture 100. The rolling component 230 is connected to the bracket 210 and is arranged close to the material suction component 220. The rolling component 230 is used to roll and laminate the film member 600 on the workpiece 500.
[0071] The material suction component 220 can include a material suction head. The material suction head is used to adsorb the film member 600 and move to the upper side of the positioning fixture 100 under the action of an external force, and then cover the film member 600 on the workpiece 500. The rolling component 230 includes a roller. When the film member 600 covers the workpiece 500, the rolling component 230 rolls the film member 600 on the workpiece 500 to discharge the air bubbles between the film member 600 and the workpiece 500.
[0072] The laminating device 1000 provided by the embodiment of the present application can improve the stability of the position of the workpiece 500 when laminating the film member 600 to the workpiece 500 through the positioning fixture 100 in the above embodiment, thereby improving the film application accuracy. The rolling component 230 in the laminating mechanism 200 can roll the film member 600 when laminating the film member 600 to the workpiece 500, effectively avoiding the generation of air bubbles between the workpiece 500 and the film member 600, and having a high film application yield.
[0073] In some embodiments, please refer to Figure 1 、 Figure 4 and Figure 5The laminating mechanism 200 further includes a deflection assembly 240, which includes a deflection drive member 241 and a rotating plate 242. The deflection drive member 241 is connected to the bracket 210. One end of the rotating plate 242 is connected to the deflection drive member 241, and the other end of the rotating plate 242 is rotatably connected to the bracket 210. The suction assembly 220 is connected to the side of the rotating plate 242 facing away from the deflection drive member 241. The rolling assembly 230 is disposed near the end of the rotating plate 242 rotatably connected to the bracket 210. The deflection drive member 241 is used to drive the rotating plate 242 and the suction assembly 220 to rotate, so that when the suction assembly 220 laminates the film 600 to the workpiece 500, one end of the film 600 is first laminar to the workpiece 500. The deflection drive member 241 can be a cylinder, etc., and the rotating plate 242 is a plate-shaped structure. Before film application, the deflection drive member 241 rotates the rotating plate 242, causing the rotating plate 242 to tilt the suction assembly 220 relative to the workpiece 500, thereby tilting the film 600 relative to the workpiece 500. At this point, the end of the film 600 away from the rolling assembly 230 is away from the workpiece 500. During film application, the suction assembly 220 approaches the workpiece 500, so that the end of the film 600 near the rolling assembly 230 first contacts the workpiece 500. The suction assembly 220 and the positioning fixture 100 then move relative to each other horizontally, gradually attaching the film 600 to the workpiece 500. The rolling assembly 230 moves synchronously with the suction assembly 220, gradually rolling the film 600. This effectively prevents the formation of bubbles between the film 600 and the workpiece 500.
[0074] It can be understood that the suction component 220 uses vacuum adsorption to position the film part 600. When the film is applied, the rolling component 230 presses one end of the film part 600. When the positioning component and the suction component 220 are relatively displaced, the force of the rolling component 230 pressing the film part 600 is greater than the adsorption force of the suction component 220 on the film part 600, thereby achieving the rolling and bonding of the film part 600 to the workpiece 500.
[0075] In some embodiments, see Figure 1 , Figure 4 and Figure 5, further including a first driving component 300 and a second driving component 400. The positioning fixture 100 is connected to the first driving component 300. The first driving component 300 is used to drive the positioning fixture 100 to move. The second driving component 400 is disposed above the first driving component 300. The laminating mechanism 200 is connected to the second driving component 400. The second driving component 400 is used to drive the laminating mechanism 200 to approach or move away from the positioning fixture 100, so that when the laminating mechanism 200 approaches the positioning fixture 100, the film member 600 is laminated on the workpiece 500. The first driving component 300 can be a linear module or the like. The positioning fixture 100 is connected to the first driving component 300 through the support plate 10 to improve the stability when moving the positioning fixture 100. The first driving component 300 is used to drive the positioning fixture 100 to move along Figure 4 the X-axis direction in
[0076] The working process of the laminating device 1000 provided by the embodiment of the present application is generally as follows:
[0077] First, the workpiece 500 is positioned by the positioning fixture 100, the film member 600 is positioned by the laminating mechanism 200, and then the first driving component 300 drives the positioning fixture 100 and the workpiece 500 to move below the second driving component 400, and the second driving component 400 drives the laminating mechanism 200 to move above the positioning fixture 100.
[0078] Before laminating, the deflection driving member 241 drives the rotating plate 242 to rotate, so that the rotating plate 242 drives the suction component 220 to tilt relative to the workpiece 500, and further makes the film member 600 tilt relative to the workpiece 500. At this time, the end of the film member 600 away from the rolling component 230 is away from the workpiece 500.
[0079] When applying the film, the second driving component 400 drives the laminating mechanism 200 to move towards the positioning fixture 100, so that the material suction component 220 approaches the workpiece 500. One end of the film member 600 that approaches the rolling component 230 first contacts the workpiece 500 and adheres to the workpiece 500. Then, the first driving component 300 drives the positioning fixture 100 to move horizontally towards the rolling component 230, and the rolling component 230 gradually rolls the film member 600 onto the workpiece 500 to laminate the film member 600 onto the workpiece 500, thereby effectively avoiding the generation of air bubbles between the film member 600 and the workpiece 500.
