Description

Technical Field

[0001] This invention relates to the field of product film application technology, specifically to a curved surface film application device and method. Background Technology

[0002] Protective film effectively protects products from external environmental influences during transportation, ensuring the stability of the product's appearance, function, and structure upon leaving the factory. Traditionally, applying film to curved products is done manually, resulting in extremely low efficiency. To address this issue, increasingly more automated film application equipment has emerged on the market.

[0003] Refer to the utility model patent with announcement number CN213735764U, which discloses a belt buckle film applicator, also known as a common curved surface film applicator. After the film is applied to the belt buckle, the belt buckle film applicator uses a rubber roller to roll on the surface of the belt buckle to smooth the film. Although this design can make the film adhere more tightly to the surface of the belt buckle, the rubber roller will exert strong pressure on the belt buckle, which can easily cause damage to the belt buckle.

[0048] Example 1

[0049] See Figures 1-9A curved surface laminating device includes a frame 1 and a conveying device 2, a laminating device 3, and a pressing device 4 mounted on the frame 1; the laminating device 3 and the pressing device 4 are both located above the conveying device 2; wherein:

[0050] The film application device 3 includes an unwinding mechanism 31, a clamping mechanism 32, a cutting mechanism 33, a stretching mechanism 34, and a film application mechanism 35. The clamping mechanism 32, the cutting mechanism 33, and the film application mechanism 35 are arranged in sequence. The film application mechanism 35 includes a first driver 351, a second driver 352, and a vacuum suction seat 353. The first driver 351 is mounted on the frame 1 and is used to drive the second driver 352 to move up and down. The vacuum suction seat 353 is mounted on the output end of the second driver 352 and is driven to move up and down by the second driver 352. The vacuum suction seat 353 has an air extraction hole and several air inlets connected to the air extraction hole. The air inlets are located at the bottom of the vacuum suction seat 353. The stretching mechanism 34 is located on the side of the cutting mechanism 33 away from the clamping mechanism 32 and is used to stretch the film.

[0051] The film pressing device 4 includes a third driver 41, a pressing block 42, and a sponge 43. The third driver 41 is mounted on the frame 1 and is used to drive the pressing block 42 to move up and down. The sponge 43 is mounted on the bottom of the pressing block 42.

[0052] The working process of the curved surface laminating equipment involved in this invention is as follows: Workpieces are placed orderly onto the conveying device 2 by manual or automatic feeding equipment. The conveying device 2 moves the workpieces. When the workpiece moves to below the laminating device 3, the film clamping mechanism 32 releases the film, and the film pulling mechanism 34 pulls the film outward from the clamping mechanism 32. At this time, the first driver 351 drives the second driver 352 downward, causing the vacuum suction seat 353 to absorb the film, while the cutting mechanism 33 cuts the film. Subsequently, the second driver 352 drives the vacuum suction seat 353 to move the film downward, gently covering the workpiece with the film. After film lamination is completed, the conveying device 2 moves the workpiece to below the pressing device 4, and the third driver 41 drives the pressing block 42 downward, causing the sponge 43 to apply flexible pressure to the workpiece, making the film adhere tightly to the workpiece. Using the design of this application, the pressing device 4 does not damage the workpiece when pressing the film onto it, significantly improving the yield rate.

[0053] In this embodiment, the conveying device 2 includes a support 21, a motor 22, a transmission belt 23, at least two transmission wheels 24, and several positioning fixtures 25. The support 21 is mounted on the frame 1. At least two transmission wheels 24 are mounted on the support 21. The transmission belt 23 is connected to each transmission wheel 24. The motor 22 is mounted on the support 21 and is used to drive any transmission wheel 24 to rotate. Several positioning fixtures 25 are evenly distributed on the transmission belt 23 and are fixedly connected to the transmission belt 23. The positioning fixtures 25 are provided with receiving grooves 251. Specifically, the workpiece to be laminated is placed in the receiving groove 251 for positioning. When the motor 22 starts, the transmission belt 23 starts to run, and then the positioning fixtures 25 move sequentially to the bottom of the laminating device 3 and the pressing device 4 to perform laminating and pressing operations.

[0054] Preferably, the bracket 21 is equipped with a first sensor 26 at the positions corresponding to the film application device 3 and the film pressing device 4. The first sensor 26 is used to detect whether the positioning fixture 25 is in place.

[0055] In this embodiment, the unwinding mechanism 31 includes an unwinding roller 311 and a plurality of side rods 312; the unwinding roller 311 is rotatably connected to the frame 1, and the plurality of side rods 312 are evenly distributed outside the unwinding roller 311. The arrangement of the plurality of side rods 312 can prevent slippage between the film roll and the unwinding roller 311, so that the film roll between the unwinding mechanism 31 and the film clamping mechanism 32 is kept as taut as possible.

[0056] In this embodiment, a fixed shaft 313 is mounted on the frame 1. Limiting plates 314 are mounted at both ends of the fixed shaft 313, and two limiting sleeves 315 are provided between the two limiting plates 314. Both limiting sleeves 315 are slidably connected to the fixed shaft 313. A spring 316 is provided between one limiting sleeve 315 and the limiting plate 314, with both ends of the spring 316 contacting the limiting plate 314 and the limiting sleeve 315 respectively. The other limiting sleeve 315 is in contact with the limiting plate 314. An unwinding roller 311 is mounted outside the fixed shaft 313, with both ends in contact with the two limiting sleeves 315 respectively. This design allows the spring 316 to apply pressure to the limiting sleeves 315, which in turn applies pressure to the unwinding roller 311, thus hindering its rotation and preventing the unwinding roller 311 from rotating under inertia and causing film relaxation.

[0057] In this embodiment, the film clamping mechanism 32 includes a fourth actuator 321, a first clamping block 322, and a second clamping block 323. The fourth actuator 321 and the first clamping block 322 are fixedly connected to the frame 1, and the second clamping block 323 is mounted on the output end of the fourth actuator 321. The second clamping block 323 is driven by the fourth actuator 321 to move up and down, so that the second clamping block 323 cooperates with the first clamping block 322 to clamp or release the film.

[0058] In this embodiment, the film-pulling mechanism 34 includes a fifth actuator 341 and a pneumatic gripper 342. The fifth actuator 341 is mounted on the frame 1 and is used to drive the pneumatic gripper 342 to approach or move away from the film-pulling mechanism 32. During film pulling, the fifth actuator 341 first drives the pneumatic gripper 342 to approach the film-pulling mechanism 32, and the pneumatic gripper 342 clamps the portion of the film exposed outside the film-pulling mechanism 32. Then, the fourth actuator 321 drives the second clamping block 323 to separate from the first clamping block 322, and the fifth actuator 341 drives the pneumatic gripper 342 to reset, causing the pneumatic gripper 342 to pull the film and move it to the side of the laminating mechanism 35 away from the film-pulling mechanism 32, so that the laminating mechanism 35 and the film-pulling mechanism 34 do not interfere with each other during operation.

[0059] In this embodiment, the cutting mechanism 33 includes a pneumatic shear 331 and a sixth actuator 332. The sixth actuator 332 is mounted on the frame 1 and is used to drive the pneumatic shear 331 to move. The direction of movement of the pneumatic shear 331 is perpendicular to the conveying direction of the pneumatic gripper 342. Specifically, the pneumatic shear 331 is used to cut the film after it is adsorbed by the vacuum suction seat 353, while the sixth actuator 332 is used to drive the pneumatic shear 331 to move outward, so as to avoid interference from the pneumatic shear 331 when the film stretching mechanism 34 is performing film stretching work.

[0060] In this embodiment, the pressure block 42 is provided with vent holes and a plurality of air blowing holes connected to the vent holes, with the air blowing holes located at the bottom of the pressure block 42; the sponge 43 is provided with a plurality of through holes corresponding one-to-one with the air blowing holes. Specifically, the air blowing holes are used to connect to an external air supply device. After the sponge 43 completes the pressing work on the film, gas is introduced into the air blowing holes, and the gas is blown along the air blowing holes to the through holes, so that the sponge 43 can be smoothly separated from the film. This design can prevent the film from being lifted by the sponge 43 due to negative pressure.

[0061] In this embodiment, the curved surface laminating equipment also includes a film cutting device 5, which is located on the side of the pressing device 4 away from the laminating device 3 and above the conveying device 2. Multiple receiving slots 251 are provided, and the positioning fixture 25 has cutting grooves 252 between each receiving slot 251. The film cutting device 5 includes a seventh driver 51, a movable plate 52, and several blades 53 corresponding to the number of cutting grooves 252 in the positioning fixture 25. The seventh driver 51 is mounted on the frame 1 and is used to drive the movable plate 52 to move up and down. The blades 53 are mounted on the bottom of the movable plate 52, and the distribution of the blades 53 corresponds one-to-one with the position of each cutting groove 252 on the positioning fixture 25. With this design, the laminating device 3 can laminate multiple workpieces at once, improving laminating efficiency. Specifically, the positioning fixture 25 of this application can accommodate multiple workpieces. When the positioning fixture 25 is conveyed to the bottom of the film-applying device 3, the film-applying device 3 applies a film segment that can cover all the workpieces on the positioning fixture 25 to the workpieces. Then the workpieces are processed by the pressing device 4. At this time, the films on each workpiece are connected to each other. Therefore, the conveying device 2 conveys the positioning fixture 25 to the bottom of the film-cutting device 5. The seventh driver 51 drives the movable plate 52 to move downward so that each blade 53 is placed into the corresponding pressing groove 252, thereby cutting and separating the film on each workpiece.

[0062] In this embodiment, the curved film laminating equipment also includes a positioning device 6. The positioning device 6 includes a positioning plate 61 and an eighth driver 62. The eighth driver 62 is mounted on the frame 1 and is used to drive the positioning plate 61 to move up and down. The positioning plate 61 is provided with a number of support plates 611 corresponding to the number of receiving slots 251 on the positioning fixture 25. Each support plate 611 is located above the conveying device 2, and a blade 53 is sandwiched between two adjacent support plates 611. A rubber pad 612 is installed at the bottom of the support plate 611. It should be noted that when the blade 53 is placed into the cutting groove 252, it will apply local pressure to the film, which can easily cause the film to separate from the workpiece. To solve this problem, this application adds a positioning device 6. Specifically, when the positioning fixture 25 moves to the bottom of the film cutting device 5, the eighth driver 62 first drives the positioning plate 61 to move down so that the support plate 611 presses the film on the workpiece. In this way, the separation of the film from the workpiece during film cutting can be avoided.

[0063] Preferably, a second sensor 521 is installed on the movable plate 52. This second sensor 521 is used to detect whether the blade 53 and the positioning plate 61 are in the correct position. Specifically, a baffle 54 is provided on the outer side of the seventh actuator 51. When the positioning plate 61 is not pressing the film, the gap between the baffle 54 and the positioning plate 61 in the vertical direction is less than the detection range of the second sensor 521. However, when the positioning plate 61 moves downward to press the film, the gap between the baffle 54 and the positioning plate 61 in the vertical direction is greater than the detection range of the second sensor 521. That is, when the blade 53 and the positioning plate 61 move downward normally, the front side of the second sensor 521 is not blocked by the baffle 54 and the positioning plate 61. At this time, the second sensor 521 determines that the blade 53 and the positioning plate 61 are working normally. Conversely, when the film cutting operation is in progress, if the second sensor 521 detects that it is blocked, it indicates that the seventh actuator 51 or the eighth actuator 62 is not operating normally, and the blade 53 and / or the positioning plate 61 are not in the correct position. Therefore, it is determined that the normal film cutting operation has not been performed, thereby controlling the equipment to stop operating.

[0064] In this embodiment, an output device 7 is provided on the side of the film cutting device 5 away from the film pressing device 4. The output device 7 includes a ninth driver 71, a connecting plate 72, and a plurality of vacuum suction heads 73 corresponding to the number of receiving slots 251 on the positioning fixture 25. The ninth driver 71 is mounted on the frame 1 and is used to drive the connecting plate 72 to move up and down and rotate. The plurality of vacuum suction heads 73 are all mounted on the connecting plate 72, and their distribution positions correspond one-to-one with the positions of the receiving slots 251 on the positioning fixture 25. Specifically, after the film is cut, the conveying device 2 moves the positioning fixture 25 to the output device 7. Then, the ninth driver 71 drives the vacuum suction heads 73 to pick up the workpiece on the positioning fixture 25 and drive the workpiece to move up and down and rotate, so as to drive the workpiece outward. Preferably, the ninth driver 71 can be composed of a telescopic cylinder and a rotary cylinder.

[0065] In this embodiment, the curved surface film application equipment also includes a control device 8, which includes a control box 81 and a control panel 82 mounted on the frame 1; the control panel 82 is electrically connected to the control box 81; the conveying device 2, the film application device 3, the film pressing device 4, the film cutting device 5, the positioning device 6, and the output device 7 are all electrically connected to the control box 81.

[0068] S1. Loading: The workpieces are placed in an orderly manner on the conveyor device 2 by manual or automatic loading equipment, and then transported by the conveyor device 2.

[0069] S2, Film application: The film pulling mechanism 34 and the film clamping mechanism 32 cooperate to pull out the film. Then, the first driver 351 drives the vacuum suction seat 353 to descend to adsorb the film, and the cutting mechanism 33 cuts the film. Then, the second driver 352 drives the vacuum suction head 73 to descend to apply the film to the workpiece.

[0070] S3, Pressing: The third driver 41 drives the pressing block 42 downward, so that the sponge 43 applies pressure to the film to press the film onto the workpiece;

[0071] S4. Film cutting: The film between connected workpieces is cut by the film cutting device 5;

[0072] S5. Discharge: Conveying device 2 outputs the workpiece that has completed the molding process to the outside.
