TECHNICAL FIELD
[0001] The present application relates to the field of light guide plate production, and particularly relates to a light guide plate injection cutting and film coating automation equipment and a cutting and film coating machine thereof. BACKGROUND
[0002] The light guide plate is made of optical grade acrylic / PC plate, and then high-tech material with extremely high refractive index and no light absorption is used to engrave light guide points on the bottom surface of the optical grade acrylic plate by laser engraving, V-shaped cross grid engraving and UV screen printing technology. The optical grade acrylic plate absorbs the light emitted from the lamp and stays on the surface of the optical grade acrylic plate. When the light hits the light guide points, the reflected light will spread to various angles, and then break the reflection condition to be emitted from the front surface of the light guide plate. Through various light guide points with different densities and sizes, the light guide plate can emit light uniformly. Due to the above characteristics, the light guide plate is widely used in the electronic product industry.
[0003] In the production process of the light guide plate, an injection molding machine is generally used to form the light guide plate, and then a water gap cutting tool is used to cut off the water gap on the injection molded light guide plate, so as to obtain the required light guide plate. Since the light needs to be emitted from the front surface of the light guide plate, the front surface of the light guide plate is required to be a high light surface. Correspondingly, the front surface of the light guide plate needs to be coated before use.
[0004] At present, in the film coating equipment for coating the light guide plate, the light guide plate with the water gap is manually transported to the saw blade device of the film coating equipment, the water gap is separated from the light guide plate by the saw blade device, and then the separated light guide plate is transferred to the film coating device of the film coating equipment by the transfer mechanism in the film coating equipment, and the film coating device is used to realize the film coating treatment of the light guide plate.
[0005] However, since the light guide plate lacks positioning before being transferred to the saw blade device, and dust is generated due to the separation of the water gap from the light guide plate by cutting, the film coating quality of the light guide plate is poor. In addition, the existing film coating equipment also has the defect of low efficiency.
[0006] Therefore, there is an urgent need for a light guide plate injection cutting and film coating automation equipment and a cutting and film coating machine to overcome one or more of the above defects. SUMMARY
[0007] An object of the present application is to provide a cutting and film coating machine to improve the film coating quality and efficiency of the light guide plate.
[0008] Another object of the present application is to provide a light guide plate injection cutting and film coating automation equipment to improve the film coating quality and efficiency of the light guide plate.
[0009] In order to achieve the above-mentioned purpose, the cutting film laminating machine comprises a rack, a positioning mechanism, a water gap cutting mechanism, a carrying mechanism and a film cutting mechanism. The rack has a horizontal mounting plate, the positioning mechanism, the water gap cutting mechanism, the carrying mechanism and the film cutting mechanism are assembled on the horizontal mounting plate, the carrying mechanism comprises a linear transfer module extending along the left-right direction of the rack, and a first pick-and-place assembly and a second pick-and-place assembly are assembled on the linear transfer module and protrude backward from the rear side of the linear transfer module to be arranged in a suspended manner. The first and second pick-and-place assemblies are also arranged separately in the left-right direction of the rack. The positioning mechanism, the water gap cutting mechanism and the film cutting mechanism are arranged separately in the left-right direction of the rack. The positioning mechanism and the water gap cutting mechanism are located beside the rear side of the linear transfer module. A dust suction head is assembled on the water gap cutting mechanism for sucking away dust generated during water gap cutting. The film cutting mechanism extends along the front-rear direction of the rack and protrudes from the linear transfer module at both ends. Under the drive of the linear transfer module, the first pick-and-place assembly transfers the light guide plate with a water gap from the positioning mechanism to the water gap cutting mechanism from above. At the same time, the second pick-and-place assembly takes away the water gap and the light guide plate cut apart at the water gap cutting mechanism and transfers the light guide plate to the film cutting mechanism.
[0010] Compared with the prior art, the light guide plate with a water gap is first positioned by the positioning mechanism before being transferred to the water gap cutting mechanism. Then, the dust suction head on the water gap cutting mechanism is used to suck away the dust generated during water gap cutting, so as to avoid the dust adhering to the light guide plate, thereby ensuring the film laminating quality of the light guide plate by the film cutting mechanism, and improving the film laminating quality of the light guide plate. In combination with the structural design that the carrying mechanism comprises a linear transfer module extending along the left-right direction of the rack and a first pick-and-place assembly and a second pick-and-place assembly assembled on the linear transfer module and protruding backward from the rear side of the linear transfer module to be arranged in a suspended manner, and the arrangement mode that the positioning mechanism, the water gap cutting mechanism and the film cutting mechanism are arranged separately in the left-right direction of the rack, the positioning mechanism and the water gap cutting mechanism are located beside the rear side of the linear transfer module, and the film cutting mechanism extends along the front-rear direction of the rack and protrudes from the linear transfer module at both ends, the light guide plate with a water gap on the positioning mechanism can be linearly transferred to the water gap cutting mechanism, and the light guide plate on the water gap cutting mechanism can be linearly transferred to the film cutting mechanism at the same time, so as to achieve the purpose of speed increase and yield increase.
[0011] To achieve the above objectives, the automated injection molding, cutting, and coating equipment for light guide plates of the present invention includes an injection molding machine for injection molding light guide plates, a robotic arm module for removing the light guide plates and sprues that are connected together and injection molded by the injection molding machine, and the aforementioned cutting and coating machine. The cutting and coating machine is located beside the injection molding machine, and the robotic arm module also transfers the light guide plates and sprues removed together from the injection molding machine to the positioning mechanism.

[0030] In order to explain the technical content and structural features of the present application in detail, the following further description is made in combination with the embodiments and the accompanying drawings.
[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the light guide plate injection cutting film automatic equipment 1000 of the present application is integrated with the light guide plate 4 injection molding, the light guide plate 4 positioning with the water hole 5, the water hole 5 cutting on the light guide plate 4 and the film operation of the light guide plate 4 cutting the water hole 5, so as to improve the automation level. Among them, the light guide plate injection cutting film automatic equipment 1000 of the present application comprises a cutting film machine 1, an injection molding machine 2 for injection molding light guide plate 4 and a mechanical hand module 3 for taking out the light guide plate 4 and water hole 5 connected together by the injection molding machine 2; the cutting film machine 1 is located beside the injection molding machine 2, which can be selected as an example in Figure 1 , the cutting film machine 1 is located beside the front side of the injection molding machine 2, of course, in other embodiments, the cutting film machine 1 can also be located beside other sides of the injection molding machine 2, so it is not Figure 1The diagram is for illustrative purposes only. The robotic arm module 3 also transfers the light guide plate 4 and sprue 5, which are removed together from the injection molding machine 2, to the positioning mechanism 20 of the cutting and laminating machine 1. This achieves the purpose of transferring the light guide plate 4 and sprue 5, formed by the injection molding machine 2, together to the positioning mechanism 20 of the cutting and laminating machine 1. It should be noted that the structures of both the injection molding machine 2 and the robotic arm module 3 are well-known in the art and will not be described in detail here.
[0032] Combined Figure 11 The cutting and coating machine 1 includes a frame 10, a positioning mechanism 20, a sprue cutting mechanism 30, a conveying mechanism 40, and a coating cutting mechanism 50. The frame 10 has a horizontal mounting plate 11, which can optionally be positioned at... Figure 2 In this example, the horizontal mounting plate 11 is located near the top of the frame 10 to facilitate the placement of other components below the horizontal mounting plate 11, such as the sprue collection box 583, the electrical control PLC housing 586, the speed controller 585, and the vacuum cleaner 587 for connection to the vacuum head 60 described below. Of course, in other embodiments, the horizontal mounting plate 11 may be located in other positions on the frame 10, so this is not the case here. Figure 2 The above is the limit.
[0033] Meanwhile, the positioning mechanism 20, the sprue cutting mechanism 30, the conveying mechanism 40, and the film-coating cutting mechanism 50 are mounted on the horizontal mounting plate 11, which provides support for them. The conveying mechanism 40 includes a linear transfer module 41 extending in the left-right direction of the frame 10, and a first pick-and-place assembly 42 and a second pick-and-place assembly 43 mounted on the linear transfer module 41 and protruding rearward from the rear side of the linear transfer module 41 in a suspended arrangement. The first and second pick-and-place assemblies 43 are also arranged separately in the left-right direction of the frame 10. The positioning mechanism 20, the sprue cutting mechanism 30, and the film-coating cutting mechanism 50 are arranged sequentially from left to right along the frame 10. Of course, in other embodiments, they can also be arranged sequentially from right to left along the frame 10. Figure 2 and Figure 3 The positioning mechanism 20 and the sprue cutting mechanism 30 are located next to the rear side of the linear transfer module 41, so that the three components are more compact. The sprue cutting mechanism 30 is equipped with a suction head 60 for removing dust generated during the cutting of the sprue 5. The coating cutting mechanism 50 extends along the front-rear direction of the frame 10 and extends out of the linear transfer module 41 at both ends, as shown in the diagram. Figure 3 As shown, the option is to... Figure 3In this configuration, the film-coating and cutting mechanism 50 is located to the side of the right end of the linear transfer module 41, making the linear transfer module 41 and the film-coating and cutting mechanism 50 more compact. However, in other embodiments, the film-coating and cutting mechanism 50 may be located to the side of the linear transfer module 41 in other directions, so this is not considered a separate configuration. Figure 3 The above is the limit.
[0034] Driven by the linear transfer module 41, the first pick-and-place component 42 transfers the light guide plate 4 with the sprue 5 from the positioning mechanism 20 to the sprue cutting mechanism 30. Simultaneously, the second pick-and-place component 43 removes the sprue 5 and the light guide plate 4, which have been cut apart at the sprue cutting mechanism 30, and transfers the light guide plate 4 to the coating and cutting mechanism 50, where the coating and cutting mechanism 50 performs a coating process on the light guide plate 4. It should be noted that the second pick-and-place component 43 can lower the sprue 5 before or after the light guide plate 4 is transferred to the coating and cutting mechanism 50 for recycling by the aforementioned sprue collection box 583. Furthermore, since the structure of the linear transfer module 41 is well known in the art, it will not be described in detail here. More specifically, as follows:
[0035] like Figures 4 to 7 As shown, the positioning mechanism 20 includes a sprue clamping assembly 21 and positioning wheels 22 arranged in a matrix on the horizontal mounting plate 11. All positioning wheels 22 together define a positioning area 23. The positioning wheels 22 can also rotate around a rotation center line 25 that is eccentrically arranged relative to the wheel center line 24 of the positioning wheel 22 to adjust the positioning area 23. That is, the size of the positioning area 23 can be obtained by rotating the positioning wheels 22 around the rotation center line 25, making the structure of the positioning mechanism 20 simple and easy to operate, and able to accurately position the light guide plate 4. The sprue clamping assembly 21 is mounted on the horizontal mounting plate 11 from below. The sprue clamping assembly 21 also passes upward through the horizontal mounting plate 11 and is placed in the middle of the positioning area 23. With the help of the sprue clamping assembly 21, the sprue 5 is clamped from below, so that the first pick-and-place assembly 42 can grab the light guide plate 4 and the sprue 5 on the positioning mechanism 20 from above. In addition, the sprue clamping assembly 21 can also ensure the stability of the light guide plate 4 after positioning. Specifically, in Figure 4 , Figure 5 and Figure 7In the embodiment, as an example, the positioning wheel 22 is provided with a mounting through hole 221 which penetrates the positioning wheel 22 from top to bottom, the mounting through hole 221 is arranged eccentrically relative to the wheel center line 24 of the positioning wheel 22, the rotation center line 25 is located at the center of the mounting through hole 221, a locking screw (not shown in the figure) penetrates the mounting through hole 221 from top to bottom and is connected with the horizontal mounting plate 11, so as to limit the positioning wheel 22 on the horizontal mounting plate 11 from top to bottom, that is, under the action of the locking screw, the positioning wheel 22 cannot move on the horizontal mounting plate 11 from top to bottom, but can rotate relative to the horizontal mounting plate 11 around the rotation center line 25; in addition, the nozzle clamping assembly 21 is a pneumatic clamping jaw, so as to simplify the structure of the nozzle clamping assembly 21. More specifically, in Figure 4 , Figure 5 and Figure 7 , as an example, the outer edge of the positioning wheel 22 is provided with a chamfer structure 222 for reducing the top size of the positioning wheel 22, so as to facilitate the mechanical hand module 3 to put the light guide plate 4 with the nozzle 5 into the positioning mechanism 20, and facilitate the first taking and placing assembly 42 to take the light guide plate 4 from the positioning mechanism 20. It should be noted that, in Figures 4 to 6 , since the injection molding machine 2 can form two light guide plates 4 at a time, correspondingly, the positioning wheel 22 is four, two for a group, and the two positioning wheels 22 in each group position a light guide plate 4 along the front and rear direction of the rack 10, the state is shown in Figure 4 and Figure 6 , of course, in other embodiments, the number of positioning wheels 22 can also be other numbers as long as the light guide plate 4 can be positioned; similarly, the injection molding machine 2 can also form one or four light guide plates 4 at a time, so it is not limited to Figure 4 and Figure 6 shown.
[0036] As Figures 8 to 10As shown, the nozzle cutting mechanism 30 comprises a stand 31, an upper moving seat 32a, a lower moving seat 32b, an upper cutter 33a, a lower cutter 33b, an upper driver 34a, a lower driver 34b, a guide body 35a, a reset spring 35b, a pressing body 35c, a pneumatic clamping jaw 36, a lateral positioning block 37a, a lateral pulling support 37b and a lateral driver 38. The stand 31 is assembled on the horizontal mounting plate 11 and protrudes upwardly from the horizontal mounting plate 11, and the horizontal mounting plate 11 is provided with a placement area 111 beside the stand 31 for placing the light guide plate 4 and the nozzle 5 to be connected together; the lateral positioning block 37a is assembled on the horizontal mounting plate 11 and protrudes into the placement area 111, the lateral driver 38 and the lateral pulling support 37b are respectively located directly below the horizontal mounting plate 11, so as to avoid the lateral driver 38 and the lateral pulling support 37b from occupying the space above the horizontal mounting plate 11, the lateral driver 38 is assembled on the horizontal mounting plate 11, and the horizontal mounting plate 11 provides support for the lateral driver 38; the lateral pulling support 37b is assembled and connected with the output end of the lateral driver 38, the lateral pulling support 37b further penetrates through the horizontal mounting plate 11 upwardly and extends into the placement area 111, and the position of the lateral pulling support 37b extending into the placement area 111 forms a lateral pulling structure 371 for cooperating with the lateral positioning block 37a in the horizontal direction, so as to be pulled tightly by the lateral pulling structure 371 and the lateral positioning block 37a along the left-right direction of the rack 10 under the driving of the lateral driver 38, and to prepare for the cutting of the nozzle 5; the pneumatic clamping jaw 36 is assembled on the horizontal mounting plate 11 from below the horizontal mounting plate 11, so as to avoid the pneumatic clamping jaw 36 from occupying the space above the horizontal mounting plate 11, and the pneumatic clamping jaw 36 further penetrates through the horizontal mounting plate 11 upwardly and is located between the lateral positioning block 37a and the lateral pulling structure 371, for clamping the nozzle 5 in the placement area 111 from below; the upper moving seat 32a is slidingly arranged on the stand 31, the upper cutter 33a is assembled on the upper moving seat 32a, the guide body 35a is slidingly arranged on the upper moving seat 32a and located beside the upper cutter 33a, and the pressing body 35c is located below the guide body 35a and fixedly connected with the guide body 35a; the reset spring 35b is sleeved on the guide body 35a, and the reset spring 35b always has a tendency to drive the pressing body 35c to slide downwardly together with the guide body 35a, so as to ensure that the pressing body 35c is lower than the upper cutter 33a, thereby ensuring that the pressing body 35c is pressed on the light guide plate 4 before the upper cutter 33a cuts the nozzle 5, and the pressing has an elastic buffering effect, which effectively avoids the light guide plate 4 from being damaged in the process of being pressed by the pressing body 35c; the upper driver 34a is assembled on the horizontal mounting plate 11, and optionally, in an example, the upper and lower drivers 34a are also located below the horizontal mounting plate 11, so as to avoid the upper driver 34a from occupying the space above the horizontal mounting plate 11, of course, in other embodiments, the upper driver 34a can also be assembled on the stand 31, so the above description is not limited thereto. Figure 8 The lower driver 34b is assembled on the horizontal mounting plate 11, and optionally, in an example, the upper and lower drivers 34a are also located below the horizontal mounting plate 11, so as to avoid the upper driver 34a from occupying the space above the horizontal mounting plate 11, of course, in other embodiments, the upper driver 34a can also be assembled on the stand 31, so the above description is not limited thereto. Figure 8As shown in the diagram; the output terminal 341 of the upper driver 34a is assembled and connected to the upper moving base 32a; the lower driver 34b, the lower moving base 32b, and the lower cutter 33b are each located directly below the horizontal mounting plate 11 to avoid them occupying the space above the horizontal mounting plate 11. The lower driver 34b is assembled to the horizontal mounting plate 11, the lower moving base 32b is assembled to the output terminal 342 of the lower driver 34b, and the lower cutter 33b is assembled to the lower moving base 32b and arranged vertically and vertically corresponding to the upper cutter 32a. Driven by the lower driver 32b, the mounting plate 11 can slide up and down relative to it; the suction head 60 is mounted on the upper moving seat 32a and adjacent to the upper cutter 33a; therefore, with the cooperation of the upper cutter 33a, the upper driver 34a, the lower cutter 33b, and the lower driver 34b, the sprue 5 is cut from the top and bottom, making the separation position of the sprue 5 and the light guide plate 4 more precise and of better quality. Furthermore, the suction head 60 directly removes dust, improving the cutting quality and preventing dust from adhering to the light guide plate 4. Specifically, in Figures 8 to 10 As an example, the sprue cutting mechanism 30 also includes an upper micrometer head 39a and a lower micrometer head 39b. The upper cutter 33a is slidably mounted on the upper shift seat 32a along the sliding direction of the side pull bracket 37b (such as the left-right direction of the frame 10), and the lower cutter 33b is slidably mounted on the lower shift seat 32b along the sliding direction of the side pull bracket 37b. The upper micrometer head 39a is assembled between the upper shift seat 32a and the upper cutter 33a, and the lower micrometer head 39b is assembled between the lower shift seat 32b and the lower cutter 33b. With the help of the upper micrometer head 39a and the lower micrometer head 39b, the positions of the upper cutter 33a and the lower cutter 33b can be adjusted accordingly with an accuracy of 0.01 mm. The adjustment is fast and the dimensional rigidity is stable, thereby accurately controlling the cutting position of the sprue 5 and the light guide plate 4. It should be noted that since injection molding machine 2 produces two light guide plates 4 in one molding process, it is required that the upper cutter 33a, lower cutter 33b, upper micrometer head 39a, and lower micrometer head 39b each be configured with two pieces, as shown in the attached diagram. Figures 8 to 10 As shown; in addition, the upper actuator 34a, the lower actuator 34b and the side actuator 38 can be cylinders or hydraulic cylinders, etc.
[0037] like Figure 11 As shown, the first pick-and-place assembly 42 includes a mounting bracket 421 mounted on the linear transfer module 41 and arranged in a suspended manner, vacuum nozzles 422 passing through the mounting bracket 421 vertically and arranged in a matrix, and pneumatic grippers 423 mounted on the mounting bracket 421 from below. Each vacuum nozzle 422 extends downward from the mounting bracket 421 and is fixedly connected to the mounting bracket 421. The vacuum nozzles 422 are configured for picking up and placing the light guide plate 4. The pneumatic grippers 423 are located between two adjacent vacuum nozzles 422 and are configured for picking up and placing the water inlet 5. Specifically, in Figure 11In the embodiment, the vacuum nozzles 422 are eight, and four of them form a group, which is responsible for the taking and placing of one light guide plate 4. As shown in Figure 11 Of course, according to actual needs, the vacuum nozzles 422 can also be other numbers, as long as they can stably take and place the light guide plates 4.
[0038] As shown in Figure 11 The second taking and placing assembly 43 comprises a mounting bracket 431 arranged on the linear moving assembly 41 in a suspended manner, vacuum nozzles 432 arranged in a matrix on the mounting bracket 431 in an up-down manner, and pneumatic clamps 433 arranged on the mounting bracket 431 from below the mounting bracket 431; each vacuum nozzle 432 extends downward from the mounting bracket 431 and is fixedly connected with the mounting bracket 431, and the vacuum nozzles 432 are configured to take and place the light guide plates 4; the pneumatic clamps 433 are located between two adjacent vacuum nozzles 432, and the pneumatic clamps 432 are configured to take and place the water inlets 5.

The mechanism frame 51 is arranged on the horizontal mounting plate 11 and is supported by the horizontal mounting plate 11, and the mechanism frame 41 protrudes upward from the horizontal mounting plate 11 and extends along the front-to-rear direction of the rack 10; the first roller 52, the second roller 53, the bearing roller 55, and the guide roller 56a are each arranged on the mechanism frame 51 and are supported by the mechanism frame 51, and the first roller 52, the second roller 53, the bearing roller 55, and the guide roller 56a each extend along the left-to-right direction of the rack 10 to ensure that the first roller 52, the second roller 53, the bearing roller 55, and the guide roller 56a are arranged in parallel on the mechanism frame 51, and the guide roller 56a, the first roller 52, and the second roller 53 are sequentially and separately arranged along the front-to-rear direction of the rack 10.
[0040] Meanwhile, the first rollers 52 are arranged in a gap-fitting manner one above the other, so that the upper first roller 52 and the lower first roller 52 define a first gap 521; the second rollers 53 are arranged in a gap-fitting manner one above the other, so that the upper second roller 53 and the lower second roller 53 define a second gap 531; the first gap 521 is aligned with the second gap 531 along the front-to-back direction of the frame 10, so as to facilitate the light guide plate 4 and the protective film 210 being conveyed together through the first rollers 52 and the second rollers 53. The bearing rollers 55 are located above the corresponding guide rollers 56a, and are selectively located, for example, directly above the guide rollers 56a, and of course, in other embodiments, the bearing rollers 55 can also be located at other positions above the guide rollers 56a, and are not limited thereto.

A first pulley 544 is fitted at the position where the output end extends out of the mechanism frame 51. A second pulley 545 is fitted at the position where the lower first roller 52 extends out of the mechanism frame 51. A third pulley 546 is fitted at the position where the lower second roller 53 extends out of the mechanism frame 51. A belt 547 is wound around the first pulley 544, the second pulley 545, and the third pulley 546. Under the operation of the rotary actuator 56b, the first pulley 544 drives the second pulley 545 and the third pulley 546 to rotate synchronously under the action of the belt 547, thereby achieving the purpose of synchronous rotation of the lower first roller 52 and the lower second roller 53. Of course, in other embodiments, the first to third pulleys 546 can be replaced by sprockets, and correspondingly, the belt 547 can be replaced by a chain. Figure 12 , Figure 13 and Figure 15 The description shown is for reference only. For a more detailed description of the structure of the film-cutting mechanism 50, please refer to the following description:
[0043] like Figures 12 to 15 and Figure 17 As shown, the mechanism frame 51 has a worktable 511 located between the first roller 52 and the second roller 53. The worktable 511 is horizontal and is arranged opposite to the first gap 521 along the left-right direction of the mechanism frame 51. (See diagram). Figure 17 As shown, the worktable 511 provides support for the unwound protective film 210 from below, and facilitates the sequential transport of the protective film 210 and the light guide plate 4 placed on it to the first roller 52 and the second roller 53. Furthermore, the left and right sides of the rear end of the frame 51 each have upwardly extending support brackets 512, with upward-facing support notches 5121. The end of the carrying roller 55 is placed on the support bracket 512 through the support notches 5121. With the help of the support notches 5121, when disassembling the carrying roller 55, it is only necessary to lift the carrying roller 55 upwards; similarly, when installing the carrying roller 55, it is only necessary to place it downwards into the support notches 5121 of the support brackets 512. Therefore, the assembly and disassembly operations between the carrying roller 55 and the frame 51 are very simple. Specifically, in Figure 13 and Figure 14As an example, the left support bracket 512 is provided with a blocking structure 5122 to prevent the bearing roller 55 from sliding in the left-right direction of the frame 10. The blocking structure 5122 faces away from the right support bracket 512, and a blocking gap 5123 is formed between the blocking structure 5122 and the support bracket 512 where the blocking structure 5122 is located. The end of the bearing roller 55 is provided with a blocking protrusion 551 for cooperating with the blocking gap 5123. With the cooperation of the blocking structure 5122 and the blocking protrusion 551, the axial movement of the bearing roller 55 is effectively prevented, thereby effectively ensuring that the bearing roller 55 moves randomly relative to the support bracket 512 when the protective film roll 200a is unwound around the bearing roller 55. In addition, the end of the guide roller 56a is rotatably connected to the support bracket 512 so that the guide roller 56a and the bearing roller 55 are installed together at the support bracket 512. It should be noted that, in other embodiments, the blocking structure 5122 may also be provided by the support bracket 512 on the right side, therefore it is not considered as such. Figure 13 and Figure 14 The above is the limit.
[0044] like Figures 12 to 16 As shown, the film-cutting mechanism 50 also includes a spare roller 57 for threading through a spare protective film roll 200a. The left and right sides of the front end of the mechanism frame 51 are provided with upwardly extending support brackets 513. Each of the left and right support brackets 513 has an upwardly facing support notch 5131. The spare roller 57 is placed on the support bracket 513 through the support notch 5131. With the help of the support notch 5131, when removing the spare roller 57, it is only necessary to lift the spare roller 57 upwards. Similarly, when installing the spare roller 57, it is only necessary to place the spare roller 57 downwards at the support notch 5131 of the support bracket 513. Therefore, the installation and removal operations between the spare roller 57 and the mechanism frame 51 are very simple. Specifically, in Figure 13 and Figure 14 In one example, the left-side support bracket 513 is provided with a limiting structure 5132 to prevent the spare roller 57 from sliding in the left-right direction of the frame 10. The limiting structure 5132 faces away from the right-side support bracket 513, and a limiting gap 5133 is formed between the limiting structure 5132 and the support bracket 513 where the limiting structure 5132 is located. The end of the spare roller 57 is provided with a limiting protrusion 571 for cooperating with the limiting gap 5133; so that the axial movement of the spare roller 57 is effectively prevented by the cooperation of the limiting structure 5132 and the limiting protrusion 571. It should be noted that in other embodiments, the limiting structure 5132 may be provided by the right-side support bracket 513, so it is not considered as a separate feature. Figure 13 and Figure 14The limit is shown; in addition, since the protective film roll 200a on the standby roller 57 is used as a standby material, after the protective film roll 200a on the bearing roller 55 is used up, the bearing roller 55 can be removed from the support bracket 512, and then the standby roller 57 is placed at the support bracket 512, so that the continuous use of the protective film 210 can be met, that is, the bearing roller 55 and the standby roller 57 can be used alternately, so the structures of the two are the same, that is, the structures of the support gap 5121 and the bearing gap 5131 are the same, the structures of the limiting gap 5133 and the blocking gap 5122 are the same, and the structures of the limiting protrusion 571 and the blocking protrusion 551 are the same.
[0045] As shown in Figures 16 to 18 , the cutting device 54 includes a cutter 541, a cutter driver 542, and a fixed bracket 543. The fixed bracket 543 extends along the left-right direction of the rack 10, and the two ends of the fixed bracket 543 are fixedly connected to the left side and the right side of the front end of the mechanism rack body 51, respectively. The cutter 541 extends along the left-right direction of the rack 10, and is located above the fixed bracket 543. The cutter driver 542 is assembled between the fixed bracket 543 and the cutter 541. This design hides the cutting device 54 in the mechanism rack body 51, making it more simple. The front and back of the cutter 541 extends to increase the transverse length of the cutter 541, so it can be applied to protective films 210 of different widths, so that the film cutting mechanism 50 can operate single or multiple films. Specifically, in Figure 17 and Figure 18 , as an example, the left side and the right side of the front end of the mechanism rack body 51 are each provided with a guide rail 514 extending up and down and located between the first roller 52 and the second roller 53. The ends of the cutter 541 are slidably connected to the guide rail 514, so that the left and right ends of the cutter 541 are each supported by the left and right sides of the mechanism rack body 51, so that the up and down sliding of the cutter 541 is more stable, smooth and consistent, effectively improving the quality of the cutting edge of the protective film 210. In addition, the cutter driver 542 is arranged in two along the left-right direction of the rack 10. Of course, one or three can be selected according to actual needs, so it is not limited to Figure 16 . More specifically, in Figure 16 , as an example, the cutter driver 542 is a pneumatic cylinder, of course, it can be a hydraulic cylinder according to actual needs, so it is not limited to this. In addition, the output end 5421 of the cutter driver 542 is arranged upward, and the cutter 541 is assembled and connected with the output end 5421 of the cutter driver 542, so as to simplify the assembly relationship between the cutter 541 and the output end 5421 of the cutter driver 542.
[0046] As shown in Figures 1 to 3 , Figures 12 to 14 , and Figures 17 to 18As shown, in order to recycle the protective film 210 together with the light guide plate 4 after cutting, the mechanism frame body 51 is further provided with a finished product collecting slide 582 in front of the second roller 53, and the finished product collecting slide 582 has a slide surface 5821 corresponding to the second gap 531, so as to facilitate the finished product to flow into the finished product collecting box 584 below the finished product collecting slide 582.
[0047] In the film cutting mechanism 50, the cutting device 54 is assembled on the mechanism frame body 51 and located between the first roller 52 and the second roller 53 along the front-to-back direction of the rack 10, and the cutting device 54 is configured to cut the protective film 210 at a position between the first and second gaps 531 upward; the rotary driver 56b is used to drive the first and second rollers 53 to rotate, which can be a rotary motor; therefore, during the film coating process of the light guide plate 4, the protective film 210 of the protective film roll 200a carried by the carrier roller 55 passes around the guide roller 56a and then passes through the first and second gaps 521 and 531; then, the second pick-and-place assembly 43 places the light guide plate 4 with the front downward on the protective film 210 at the position between the first roller 52 and the guide roller 56a; then, the rotary driver 56b is started to drive the first and second rollers 53 to rotate, so that the light guide plate 4 and the protective film 210 are pressed and adhered together at the first gap 521, and the adhered light guide plate 4 and protective film 210 are adhered again and sent out at the second gap 531, and before the second adhesion, the protective film 210 adhered to the light guide plate 4 is separated from the protective film roll 200a by the cutting device 54, realizing the integration of film coating and cutting; in combination with the cutting device 54 assembled on the mechanism frame body 51 and located between the first roller 52 and the second roller 53 along the front-to-back direction of the rack 10, this arrangement makes the cutting device 54 compact between the first roller 52 and the second roller 53, so that the film cutting mechanism 50 has the advantage of compact structure.
[0048] The working principle of the light guide plate injection molding cutting and film coating automatic equipment is described in combination with the drawings: the light guide plate 4 is first formed by the injection molding machine 2; then, the mechanical hand module 3 takes out the light guide plate 4 and the water gap 5 from the injection molding machine 2, and then transfers the light guide plate 4 and the water gap 5 to the positioning mechanism 20 for positioning; after positioning, under the driving of the linear transfer module 41, the first taking and placing assembly 42 transfers the light guide plate 4 and the water gap 5 at the positioning mechanism 20 to the water gap cutting mechanism 30, at the same time, the second taking and placing assembly 43 slides to the film cutting mechanism 50, so that the second taking and placing assembly 43 can take away the water gap 5 and the light guide plate 4 that have been cut and separated at the water gap cutting mechanism 30, and make the light guide plate 4 separated from the water gap 5 transfer to the film cutting mechanism 50 for film coating treatment; and the film coated light guide plate 4 is transferred to the forming collection box 584 for collection and treatment by means of the finished product collection slide 582. It should be noted that the cutting frequency of the cutting device 54 and the rotating speed of the rotating driver 56b can be controlled by the speed regulator 585.
[0049] Compared with the prior art, the light guide plate 4 with the water gap 5 is first positioned by means of the positioning mechanism 20 before being transferred to the water gap cutting mechanism 30, and then the dust generated in the cutting process of the water gap 5 is sucked away by the dust suction head 60 on the water gap cutting mechanism 30, so as to avoid the dust adhering to the light guide plate 4, thereby ensuring the film coating quality of the light guide plate 4, and improving the film coating quality of the light guide plate 4; in combination with the structural design that the conveying mechanism 40 comprises the linear transfer module 41 extending along the left-right direction of the rack 10, and the first taking and placing assembly 42 and the second taking and placing assembly 43 are arranged in a suspended manner on the linear transfer module 41 and protrude from the rear side of the linear transfer module 41, and the arrangement mode that the positioning mechanism 20, the water gap cutting mechanism 30 and the film cutting mechanism 50 are arranged in sequence along the left-right direction of the rack 10, the positioning mechanism 20 and the water gap cutting mechanism 30 are located beside the rear side of the linear transfer module 41, and the film cutting mechanism 50 extends along the front-rear direction of the rack 10 and protrudes from the front-rear ends of the linear transfer module 41, the light guide plate 4 with the water gap 5 on the positioning mechanism 20 can be linearly transferred to the water gap cutting mechanism 30, and the light guide plate 4 on the water gap cutting mechanism 30 can be linearly transferred to the film cutting mechanism 50 at the same time, so as to achieve the purpose of speed increase and yield increase.
[0050] It should be noted that the direction indicated by the arrow A in the drawings is the direction from left to right of the rack 10, the direction indicated by the arrow B in the drawings is the direction from front to back of the rack 10, and the direction indicated by the arrow C in the drawings is the direction from top to bottom of the rack 10. In addition, on the basis of the above-mentioned arrangement mode, the conveying mechanism 40 can be arranged in the following manner: Figure 18In the middle, the opposite direction indicated by arrow B is the conveying direction of the protective film 210 together with the light guide plate 4, and the light guide plate 4 can be a thin plate. In addition, in order to realize full automatic control, the light guide plate injection molding cutting and film covering automation equipment 1000 of the present application can be electrically connected with a controller, and the automatic operation of the light guide plate injection molding cutting and film covering automation equipment 1000 of the present application is controlled by the program built in the controller.
