Description

Technical Field

[0001] The present application relates to the technical field of polarizing film production, and in particular to a loading jig and a baking edge device for a polarizing film baking edge device. Background Art

[0002] A polarizing film is a transparent film based on a polymer material that can generate polarized light or suppress the polarization effect of the film. Its main function is to control the direction and transmission of light waves. By selectively allowing light waves with a specific polarization direction to pass through while blocking or weakening light waves with other polarizations. This property makes the polarizing film widely used in fields such as display panels and sunglasses.

[0003] In the production process of polarizing films, a polarizing film baking edge device is used to bend the polarizing film according to specific curvatures and shapes to meet the requirements of different application scenarios. With the popularization of semi-automatic production technology, the baking edge device mainly includes a material taking mechanism and a baking edge mechanism. The material taking mechanism grabs the stacked polarizing films one by one and places them into the baking edge mechanism for heating and baking edge operations. During production, when polarizing film sheets are stacked together, the polarizing film sheets are prone to adhere to each other, so that when the material taking mechanism grabs, it is easy to grab two polarizing film sheets, which is likely to affect production. Summary of the Invention

[0004] In a first aspect, the present application provides a loading jig for a polarizing film baking edge device.

[0005] The present application adopts the following technical solutions:

[0006] A loading jig for a polarizing film baking edge device includes a material bearing mechanism and a material grabbing mechanism; the material bearing mechanism includes a material bearing plate and a plurality of upright columns arranged on the material bearing plate, and the plurality of upright columns enclose a material bearing space for placing polarizing film sheets; the material grabbing mechanism includes a mounting seat, a driving source for driving the mounting seat to move up and down in the material bearing space, and a suction nozzle arranged on the lower surface of the mounting seat; a sliding groove is formed in the side wall of the mounting seat, and a sliding rod is slidably arranged in the sliding groove, an elastic member is arranged between the sliding rod and the sliding groove, a convex block is arranged on the side wall of the sliding rod, and a stepped edge is arranged at the opening of the sliding groove, and the convex block can abut against the stepped edge under the action of the elastic member;

[0007] A resistance block is provided on the side wall of the column, and the resistance block has an inclined surface inclined upward and a vertical surface perpendicular to the surface of the column on a side close to the sliding rod; when the mounting seat moves downward, the mounting seat can drive the resistance block to slide into the column so that the resistance block and the sliding rod are not in contact; when the mounting seat moves upward, the end of the sliding rod can abut against the inclined surface and be pressed by the inclined surface to slide into the sliding groove; when the sliding rod moves to the vertical surface, the elastic member drives the sliding rod to pop out and causes the resistance block to knock on the step edge.

[0008] By adopting the above technical solution, the abutment block has an inclined surface and a vertical surface. When the mounting seat moves downward, the abutment block can slide into the column, thereby not affecting the downward movement of the mounting seat. When the mounting seat moves upward, the end of the sliding rod abuts against the inclined surface, so that the sliding rod slides into the sliding groove. When the sliding rod and the inclined surface are out of contact, the elastic member drives the sliding rod to pop out, and the protrusion hits the step edge, thereby generating vibration on the mounting seat. When the polarizing films stick together, the vibration of the mounting seat is conducive to the excess polarizing films falling downward.

[0009] Optionally, a accommodating cavity is provided in the column, and an internal hollow mounting tube is slidably arranged up and down in the accommodating cavity, and a makeshift hole connected to the accommodating cavity is provided on the side wall of the column; the resistance block is slidably arranged in the mounting tube, and a first reset member is arranged between the resistance block and the mounting tube, and a second reset member is arranged between the mounting tube and the bottom surface of the accommodating cavity; a driving member is arranged on the column, and when the mounting seat moves downward, the driving member drives the mounting tube to move downward, and the resistance block slides into the mounting tube, and the first reset member and the second reset member are both in a compressed state.

[0010] By adopting the above technical solution, the mounting seat moves downward, that is, the driving member can drive the mounting tube to move downward, and the inclined surface is pressed against the side wall of the column, thereby sliding into the mounting tube. After the mounting seat moves downward, the second reset member drives the mounting tube to reset upward, and the first reset member drives the abutment block to reset.

[0011] Optionally, the driving member includes a driving column horizontally slidably arranged on the side wall of the column, the driving column extends into the accommodating cavity, and a third reset member is arranged between the driving column and the inner wall of the accommodating cavity, the driving column is located above the mounting tube and an interference portion is arranged between the driving column and the mounting tube, and an end of the driving column facing away from the mounting seat has a surface extending beyond the column, and when the mounting seat moves downward, it can push the driving column to slide into the accommodating cavity, and the driving column pushes the mounting tube to move downward through the interference portion.

[0012] By adopting the above technical solution, the mounting seat pushes the driving column to slide, and pushes the mounting cylinder to move downward through the abutting portion.

[0013] Optionally, the abutting portion includes a first arc-shaped block disposed on the side wall of the driving column and a second arc-shaped block disposed on the surface of the mounting cylinder. When the driving column slides into the accommodating cavity, the first arc-shaped block abuts against the second arc-shaped block.

[0014] By adopting the above technical solution, the first arc-shaped block and the second arc-shaped block abut against each other, so as to achieve the purpose of pushing the mounting cylinder to move downward.

[0015] Optionally, the mounting seat is provided with an extension portion. When the mounting seat moves downward, the extension portion abuts against the end face of the driving column and pushes the driving column to slide into the accommodating cavity.

[0016] Optionally, the end of the driving column is of an arc-shaped structure.

[0018] Optionally, an installation cavity is provided on the side wall of the column. The installation cavity is located below the accommodating cavity. An airbag is installed in the installation cavity, and a slot communicating with the installation cavity is provided on the side wall of the column. An extrusion member is provided in the installation cavity. The extrusion member is located above the airbag. The extension portion can drive the extrusion member to move downward, so that a part of the airbag is extruded from the slot and abuts against the side wall of the polarizing film; an opening is provided on the lower surface of the material bearing plate. The material bearing mechanism further includes a power source and a lifting plate. The power source drives the lifting plate to move upward and passes through the opening.

[0019] By adopting the above technical solution, when the mounting seat moves downward, the extension portion drives the extrusion member to move downward, so that a part of the airbag is extruded from the opening and abuts against the side wall of the stacked polarizing films, so that when taking materials, the adhered polarizing films are more likely to be separated.

[0020] Optionally, the extrusion member includes an extrusion plate disposed in the installation cavity and an extension rod disposed on the extrusion plate. A limiting groove is provided on the side wall of the column. The upper end of the extension rod extends out of the limiting groove.

Detailed implementation manners

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] Embodiment 1

[0035] The embodiment of the present application discloses a loading jig for a polarizing film edge baking device. Refer to Figure 1 and Figure 2 , the loading jig is applied to the edge baking device. The loading jig includes a material supporting mechanism 1 and a material grasping mechanism 2. The material supporting mechanism 1 is used for holding the polarizing film to be processed, and the polarizing film is stacked in the material supporting mechanism 1. The material grasping mechanism 2 is used to grab the polarizing film one by one and place it on the subsequent processing station.

[0036] The material supporting mechanism 1 includes a material supporting plate 101 and a plurality of columns 102 arranged on the material supporting plate 101. The columns 102 are circumferentially distributed, and a material supporting space 103 is enclosed between the columns 102. The polarizing film is placed in the material supporting space 103. Each material supporting space 103 corresponds to 8 columns 102. Two groups of columns 102 can be arranged on the material supporting plate 101, so as to have two material supporting spaces 103. By sliding the material supporting plate 101, another material supporting space 103 can correspond to the material grasping mechanism 2, improving the production efficiency. The material grasping mechanism 2 includes a mounting seat 201, a driving source 203 for driving the mounting seat 201 to move up and down, and a suction nozzle 202 arranged on the lower surface of the mounting seat 201. The driving source 203 is preferably a cylinder. The mounting seat 201 is installed at the lower end of the piston rod of the cylinder. By driving the mounting seat 201 to move downward into the material supporting space 103 by the cylinder, after the suction nozzle 202 grabs the uppermost polarizing film, the mounting seat 201 moves upward, and the polarizing film can be taken out.

[0037] Reference Figure 3 and Figure 4 Figure 4 [Reference Figure 3 and

[0037] , a sliding groove 3 is formed in the side wall of the mounting base 201, and a sliding rod 4 is slidably connected in the sliding groove 3. The sliding rod 4 slides in the horizontal direction.] Figure 2 Figure 2 [In this embodiment, there are four sliding grooves 3, and the sliding rods 4 correspond to the sliding grooves 3 one by one. The opening of the sliding groove 3 has a constricted structure, so that a stepped edge 7 is formed at the opening of the sliding groove 3. For the convenience of installation, the mounting base 201 can be a split structure. A convex block 6 is provided on the outer wall of the sliding rod 4, and an elastic member 5 is provided between the sliding rod 4 and the sliding groove 3. Under the action of the elastic member 5, the convex block 6 abuts against the stepped edge 7, and the end of the sliding rod 4 extends beyond the side wall of the mounting base 201.]

[0038] Reference Figure 5 and Figure 6 Figure 6 [Reference Figure 5 and

[0038] , a contact block 8 is mounted on the side wall of the column 102 corresponding to the sliding rod 4. One side of the contact block 8 close to the adjacent sliding rod 4 has an inclined surface 9, and the upper surface of the contact block 8 is a vertical surface 10 perpendicular to the surface of the column 102. The vertical surface 10 is connected to the inclined surface 9.] Figure 4 Figure 4 [When the mounting base 201 moves upward, the end of the sliding rod 4 abuts against the inclined surface 9. The sliding rod 4 is pressed by the inclined surface 9 and slides into the sliding groove 3, and the elastic member 5 is compressed. When the sliding rod 4 and the inclined surface 9 are disengaged, the sliding rod 4 pops out under the action of the elastic member 5, and the convex block 6 impacts on the stepped edge 7, so that the mounting base 201 can generate vibration and be transmitted to the suction nozzle 202. Therefore, if the polarizing film sheets are adhered together due to static electricity or other reasons, the redundant polarizing film sheets can be shaken off.]

[0039]

[0039] [The contact block 8 is linked with the mounting base 201. During the downward movement of the mounting base 201, the contact block 8 can slide into the column 102, so that the contact block 8 and the sliding rod 4 are not in contact, thus not affecting the downward movement of the mounting base 201. When the mounting base 201 moves upward, the contact block 8 can push the sliding rod 4 to slide.]

[0040] Reference Figure 6, a receiving chamber 11 is provided in the column 102, and a mounting tube 12 that slides up and down is installed in the receiving chamber 11. A plate body 31 is slidably installed in the receiving chamber 11, and the mounting tube 12 is installed on the upper surface of the plate body 31. The plate body 31 abuts against the inner wall of the receiving chamber 11, and a guide block groove structure can be set to limit the position, so that the plate body 31 can slide up and down stably. A clearance hole 13 connected to the receiving chamber 11 is provided on the side wall of the column 102, and the resistance block 8 is slidably installed in the mounting tube 12, and one end of the resistance block 8 extends from the clearance hole 13. A first reset member 14 is provided between the mounting tube 12 and the resistance block 8, and the first reset member 14 is a spring. Under the action of the first reset member 14, the resistance block 8 passes through the clearance hole 13. When the mounting tube 12 moves downward, the inclined surface 9 is pressed by the inner wall of the receiving chamber 11 and slides into the mounting tube 12, and the first reset member 14 is compressed.

[0041] A second reset member 15 is provided between the lower surface of the plate body 31 and the inner bottom surface of the accommodating chamber 11. The second reset member 15 is a spring. When the mounting tube 12 moves downward, the second reset member 15 is compressed, providing a force for the mounting tube 12 to reset upward. The force provided by the second reset member 15 for the mounting tube 12 to reset upward is greater than the friction between the abutment block 8 and the inner wall of the accommodating chamber 11, so that the second reset member 15 can drive the mounting tube 12 to reset upward.

[0042] Reference Figure 4 and Figure 6 , a driving member 16 is installed on the column 102. When the mounting seat 201 moves downward, the mounting tube 12 is pushed downward by the driving member 16. The driving member 16 includes a driving column 161 slidably connected to the side wall of the column 102. The driving column 161 extends into the accommodating cavity 11 and is located above the mounting tube 12. A third reset member 162 is provided between the driving column 161 and the inner wall of the accommodating cavity 11. The third reset member 162 is preferably a spring. The driving column 161 can be a hollow structure. One end of the third reset member 162 is connected to the inner cavity of the driving column 161. Under the action of the third reset member 162, one end of the driving column 161 has a portion that exceeds the surface of the column 102, and the end is located on the side of the column 102 away from the abutment block 8. An abutment portion 17 is provided between the driving column 161 and the mounting tube 12 . When the mounting seat 201 moves downward, the driving column 161 can be pushed to slide into the accommodating cavity 11 , the third reset member 162 is compressed, and the driving column 161 pushes the mounting tube 12 to move downward through the abutment portion 17 .

[0043] Reference Figure 6 The abutment portion 17 includes a first arc block 171 fixed to the side wall of the driving column 161 and a second arc block 172 fixed to the side wall of the mounting tube 12. When the driving column 161 slides, the first arc block 171 abuts against the second arc block 172 and pushes the mounting tube 12 to move downward.

[0044] Referring to Figure 3 and Figure 6 , an extension part 18 is fixed on the side wall of the mounting seat 201. During the downward movement of the mounting seat 201, the extension part 18 can first contact the end of the driving column 161, thereby pushing the driving column 161 to slide. One end of the driving column 161 extending beyond the surface of the column 102 is an arc structure, which is more conducive to the extension part 18 pushing the driving column 161 to slide. When the mounting seat 201 moves downward, after the extension part 18 first pushes the driving column 161 to slide, the sliding rod 4 then moves to the position of the abutting block 8, and during this process, the abutting block 8 remains in the state of being received in the mounting cylinder 12, so as not to affect the downward movement of the sliding rod 4 along with the mounting seat 201. When the mounting seat 201 moves upward, the sliding rod 4 first cooperates with the abutting block 8. After the sliding rod 4 and the abutting block 8 are separated, the extension part 18 then cooperates with the driving column 161, so that the extension part 18 does not affect the cooperation between the abutting block 8 and the sliding rod 4 during the upward movement.

[0045] Referring to Figure 2 and Figure 6 , an installation cavity 19 is formed in the side wall of the column 102, and the installation cavity 19 is located below the accommodation cavity 11. An airbag 20 is installed in the installation cavity 19, and a slot 21 communicating with the installation cavity 19 is formed in the side wall of the column 102. The position of the slot 21 corresponds to the height of the stacked polarizing film sheets in the material receiving space 103. An extrusion member 22 is also arranged in the installation cavity 19. When the mounting seat 201 moves downward, the extension part 18 can abut against the extrusion member 22, and the airbag 20 is extruded through the extrusion member 22. A part of the airbag 20 can be extruded from the slot 21 and abut against the side wall of the stacked polarizing film sheets. Therefore, there is a certain friction between the polarizing film sheets and the airbag 20, further reducing the situation of the polarizing film sheets overlapping during material taking. In other embodiments, in order to improve the abutting effect on the polarizing film sheets, a plurality of brush-shaped extension strips are fixedly arranged at intervals on the side wall of the airbag 20 corresponding to the slot 21. By using the extension strips to abut against the polarizing film sheets, it is not easy to affect the material taking of the polarizing film sheets, and the situation of grabbing two polarizing film sheets can be reduced.

[0046] Referring to Figure 2 , the material receiving mechanism 1 further includes a power source 104 and a lifting plate 105. The power source 104 can be structures such as a cylinder or a telescopic cylinder, and the piston rod is connected to the lower surface of the lifting plate 105. An opening 23 is formed in the material receiving plate 101. When the power source 104 drives the lifting plate 105 to move up and down, the lifting plate 105 can lift the polarizing film sheets in the material receiving space 103 upward, so that the upper end height of the polarizing film sheets corresponds to the position of the airbag 20. The power source 104 can be fixed at some external installation positions.

[0047] The extruded part 22 includes an extrusion plate 221 disposed in the installation cavity 19, and an extension rod 222 disposed on the extrusion plate 221. Structures such as guide blocks and guide grooves are provided between the extrusion plate 221 and the inner wall of the installation plate cavity for limiting, so that the extrusion plate 221 can slide up and down stably. A limiting groove 24 is formed on the side wall of the column 102, and the upper end of the extension rod 222 extends out of the limiting groove 24. When the mounting seat 201 moves downward, the extension part 18 can abut against the extension rod 222 and push the extrusion plate 221 to slide downward, thereby extruding the airbag 20.

[0048] The implementation principle of the loading jig of the polarizing film edge baking device in the embodiment of the present application is as follows: during the downward movement of the mounting seat 201, the driving column 161 can drive the mounting cylinder 12 to move downward, so that the abutting block 8 slides into the mounting cylinder 12, and the abutting block 8 does not affect the sliding rod 4 to move downward along with the mounting seat 201; during the upward movement of the mounting seat 201, the elastic force of the first resetting member 14 is greater than the elastic force of the elastic member 5, and the sliding rod 4 can be pressed by the abutting block 8 and slide into the sliding groove 3. After the sliding rod 4 is separated from the inclined surface 9, the sliding rod 4 pops out, and the convex block 6 hits the stepped edge 7, so that the excess polarizing film can be shaken off.

[0049] Embodiment 2

[0050] Refer to Figure 1 A baking device includes a workbench 25, the loading jig in Embodiment 1, a positioning mechanism 26, and a baking mechanism 27. A sliding plate 28 is slidably disposed on the workbench 25. The sliding plate 28 is fixed to the workbench 25 through an additionally provided frame to provide necessary installation, which is not shown in the figure. The sliding plate 28 is driven by a cylinder, an electric telescopic cylinder, a lead screw, etc., and the sliding plate 28 can reciprocate horizontally. The material grabbing mechanism 2 in Embodiment 1 is disposed on the sliding plate 28, and a first material taking member 29 and a second material taking member 30 are disposed on the sliding plate 28. The first material taking member 29 and the second material taking member 30 can be selected from suction cups driven by a cylinder to move up and down. When the material grabbing mechanism 2 corresponds to the material receiving mechanism 1, the first material taking member 29 corresponds to the positioning mechanism 26, and the second material taking member 30 corresponds to the baking mechanism 27. The power source 104 is installed on the lower surface of the workbench 25, and the material receiving plate 101 slides on the surface of the workbench 25 through a slide rail and is driven to slide by a cylinder.

[0051] After the material grabbing mechanism 2 grabs the polarizing film, the sliding plate 28 slides, so as to place the polarizing film in the positioning mechanism 26, and the first material taking member 29 places the polarizing film in the positioning mechanism 26 into the baking mechanism 27, and the second material taking member 30 places the polarizing film in the baking mechanism 27 into the subsequent station.

[0052] In this embodiment, the positioning mechanism 26 includes a platform plate 261 and a positioning cylinder 262 mounted on the platform plate 261. There are four positioning cylinders 262, and positioning blocks are fixed on the piston rods of the positioning cylinders 262. The material grabbing mechanism 2 places the polarizing film between the four positioning cylinders 262, and the four positioning cylinders 262 move synchronously, so as to adjust the position of the polarizing film to the central position of the four positioning cylinders 262. Then the first material taking member 29 grabs the polarizing film and can accurately place it in the subsequent edge baking mechanism 27.

[0053] Referring to Figure 1 , the edge baking mechanism 27 includes a support table and four heating seats 271 arranged on the support table. The heating seats 271 are circumferentially distributed, and the polarizing film is placed between the four heating seats 271, so as to heat the edge position of the polarizing film, so that the edge of the polarizing film is heated and bent. After edge baking, the polarizing film is placed in the subsequent process through the second material taking member 30 for subsequent operations.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered by the protection scope of the present application.
