Description

Technical Field

[0001] This invention relates to the field of flexible circuit board production equipment technology, specifically to an automatic lamination equipment for long-width cover film. Background Technology

[0002] With the development of electric vehicles, the market demand for flexible circuit boards (PCBs) used in automotive electronics has surged. To improve production efficiency, multiple PCBs are typically panelized for production. However, because automotive PCBs are generally large, the resulting panelized products are quite long, reaching approximately 1.5 meters. During production, a CVL (Continuous Vibration Film) cover film may need to be applied to the surface of the PCB for protection. Existing lamination equipment can only apply film to products up to 500mm in length. While some equipment can apply film to 1.5-meter products, manual peeling of the cover film from the release film is required before the equipment attaches it to the product, resulting in low efficiency and significant manual labor costs. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an automatic long-width cover film laminating device that can automatically apply cover film to long products up to 1.5 meters long, thereby improving the laminating efficiency of long products.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A long-width automatic cover film laminating device, comprising a cover film feeding mechanism, a peeling mechanism, a receiving platform, a cover film conveying mechanism, a feeding mechanism, a laminating platform, a hot pressing mechanism, and a receiving mechanism; the cover film feeding mechanism is used to carry stacked cover film raw materials and feed the cover film raw materials into the peeling mechanism; the peeling mechanism is located on the outlet side of the cover film feeding mechanism and is used to peel off the release film from the cover film raw materials and feed the peeled cover film into the receiving platform, while simultaneously feeding the peeled release film into a release film hopper below the receiving platform; the receiving platform is located inside the peeling mechanism and is used to carry and temporarily store the cover film peeled off by the peeling mechanism, the receiving platform has adsorption capacity, and the receiving platform can adsorb the cover film placed on it; the feeding mechanism is located on the inlet side of the laminating platform and is used to unwind the roll of the product to be laminated. The unwound product is fed onto the bonding platform. The bonding platform, located on one side of the receiving platform, receives the product to be bonded from the unloading mechanism and provides bottom support for the product. The bonding platform has adsorption capacity and can hold the product placed on it. The cover film transport mechanism, located above the bonding platform and the receiving platform, moves the cover film on the receiving platform to cover the product on the bonding platform, thus initially bonding the cover film to the product. The heat-pressing mechanism, located on the exit side of the bonding platform, heat-presses the product initially bonded on the bonding platform. The take-up mechanism, located on the exit side of the heat-pressing mechanism, provides traction force to the product to be bonded from the unloading mechanism, allowing the product to pass sequentially through the bonding platform and the heat-pressing mechanism, and rewinds the product after heat-pressing by the heat-pressing mechanism into a roll.

[0005] Compared to existing technologies, the advantages of this invention are as follows: The cover film feeding mechanism can feed stacked sheet-like cover film raw materials into the peeling mechanism, where the peeling mechanism separates the cover film from the release film and feeds the cover film onto the receiving platform. The receiving platform, due to its adsorption capacity, can prevent wrinkles from forming in the peeled cover film. The cover film transport mechanism transports the cover film from the receiving platform to the product on the lamination platform, completing the pre-lamination of the cover film. The hot-pressing mechanism then hot-presses the pre-lamination onto the product, temporarily attaching the cover film to it, thus completing the temporary lamination of the cover film. Finally, the receiving mechanism collects the laminated product into rolls for use in subsequent processes. This equipment can automatically complete the temporary lamination of cover film for long products without human intervention, improving the efficiency of temporary lamination of cover film for long products, reducing manpower requirements in the lamination process, and lowering the manufacturing cost of flexible circuit boards.

[0006] The aforementioned automatic long-width cover film laminating equipment further includes a lower photographing mechanism and an upper photographing mechanism. The lower photographing mechanism is located below the cover film transport mechanism and is used to photograph the cover film on the cover film transport mechanism.

The oscillating pressure roller, driven by the oscillating drive mechanism, presses against the first transition roller or the second transition roller. The upper end of the stripping guide channel is located behind the second transition roller, and the lower end is located at the entrance of the release film hopper. A release film guide roller is rotatably mounted at the lower end of the stripping guide channel. The separating pressure roller is located at the entrance of the stripping channel. Driven by the separating pressure roller drive mechanism, the separating pressure roller presses the front end of the stripped release film into the stripping channel. The stripping fork is located on the second... Behind the transition roller, the height of the peeling fork is flush with the peeling platform. The peeling fork can reciprocate along the length of the cover film material under the drive of the peeling fork translation drive mechanism, so that the peeling fork extends between the peeled cover film and the release film. The traction gripper can clamp the front end of the peeled cover film on the peeling fork. The traction gripper can reciprocate along the length of the cover film material under the drive of the traction drive mechanism, so as to pull the peeled cover film to the receiving platform. The rear end of the peeling fork has a fork-shaped structure so that the traction gripper can clamp the front end of the peeled cover film from the peeling fork.

[0009] The aforementioned automatic long-width cover film laminating equipment includes a cover film transport mechanism comprising a transport gantry and two sets of transport robotic arms.

Detailed Implementation

[0035] The embodiments of the present invention are described in detail below, with reference to... Figure 1This invention provides an automatic long-width cover film laminating device, including a cover film feeding mechanism 100, a peeling mechanism 200, a receiving platform 300, a cover film transport mechanism 500, a discharging mechanism 600, a laminating platform 700, a hot-pressing mechanism 800, and a receiving mechanism 900. The cover film feeding mechanism 100 carries stacked cover film raw materials and feeds them into the peeling mechanism 200. The peeling mechanism 200 is located on the outlet side of the cover film feeding mechanism 100 and peels off the release film from the cover film raw materials, feeding the peeled cover film onto the receiving platform 300. Simultaneously, it feeds the peeled release film into a release film hopper 400 below the receiving platform 300. The receiving platform 300 is located within the peeling mechanism 200 and carries and temporarily stores the cover film peeled off by the peeling mechanism 200. The receiving platform 300 has adsorption capacity, allowing it to hold the cover film placed on it. A feeding mechanism 600 is located on the inlet side of the laminating platform 700. It unwinds the roll of product to be laminated and feeds the unwound product onto the laminating platform 700. The laminating platform 700 is located on one side of the receiving platform 300. It receives the product to be laminated from the feeding mechanism 600, providing bottom support for the product. The laminating platform 700 has adsorption capacity, allowing it to hold the product placed on it. A cover film conveying mechanism 500 is located above the laminating platform 700 and the receiving platform 300. It moves the cover film from the receiving platform 300 to cover the product on the laminating platform 700, thus initially laminating the cover film onto the product. A heat-pressing mechanism 800 is located on the outlet side of the laminating platform 700. It performs heat-pressing on the initially laminated product on the laminating platform 700. The receiving mechanism 900 is located on the exit side of the hot pressing mechanism 800. It is used to provide traction force for the product to be laminated released by the feeding mechanism 600, so that the product can pass through the lamination platform 700 and the hot pressing mechanism 800 in sequence, and re-receive the product after hot pressing by the hot pressing mechanism 800 into a roll.

[0036] In operation, this long-width automatic cover film laminating equipment works as follows: The cover film feeding mechanism 100 feeds stacked sheet-like cover film raw materials one by one into the peeling mechanism 200. The peeling mechanism 200 separates the cover film from the release film in the cover film raw materials, and then feeds the peeled cover film and release film into the receiving platform 300 and the release film hopper 400 below the receiving platform 300, respectively. The receiving platform 300, due to its adsorption capacity, can hold the cover film placed on it to prevent wrinkles. The cover film transport mechanism 500 transports the cover film from the receiving platform 300 to the product on the laminating platform 700, and initially adheres the cover film to the product. Subsequently, the product is drawn by the receiving mechanism 900 and fed into the hot pressing mechanism 800. After hot pressing by the hot pressing mechanism 800, the cover film is temporarily adhered to the product. Finally, the receiving mechanism 900 collects the material into a roll for use in the next stage. This equipment can automatically apply 1.5-meter-long cover film without human intervention, which can improve the efficiency of cover film application for long flexible circuit boards, reduce the manpower required for application, and reduce the production cost of long flexible circuit boards.

[0037] Reference Figure 2 and Figure 3In this embodiment, the cover film feeding mechanism 100 includes a lifting and stacking platform 110, a stacking platform lifting drive mechanism 130, and a cover film gripping mechanism 120. The cover film gripping mechanism 120 includes a cover film suction cup 121, a cover film lifting drive mechanism 122, and a cover film translation drive mechanism 123. The lifting and stacking platform 110 can move up and down under the drive of the stacking platform lifting drive mechanism 130, raising the uppermost cover film material to a fixed height, facilitating the cover film suction cup 121 to pick up the cover film material from the lifting and stacking platform 110. At least one side of the lifting and stacking platform 110 is provided with a plurality of antistatic brushes 113, and at least one side of the lifting and stacking platform 110 is provided with an air blowing device 114. The antistatic brushes 113 can remove static electricity between the cover film materials, while the air blowing device 114 can blow air towards the edges of the cover film material on the lifting and stacking platform 110, thereby preventing multiple pieces of cover film material from sticking together when being picked up. The cover film suction cup 121 is equipped with multiple adjustable vacuum suction cups, which are connected to a vacuum source to pick up the cover film material. The cover film suction cup 121 is mounted on the cover film lifting drive mechanism 122, which in turn is mounted on the cover film translation drive mechanism 123. The cover film suction cup 121 can move up and down under the drive of the cover film lifting drive mechanism 122, which in turn can reciprocate along the length of the cover film material under the drive of the cover film translation drive mechanism 123, so as to feed the front end of the picked-up cover film material into the peeling mechanism 200. The cover film suction cup 121 descends under the drive of the cover film lifting drive mechanism 122 and picks up a piece of cover film material. Then, under the drive of the cover film lifting drive mechanism 122, it is raised to be level with the inlet of the peeling mechanism 200. Subsequently, the cover film translation drive mechanism 123 drives the cover film suction cup 121 to move towards the peeling mechanism 200 to send the front end of the picked-up cover film material into the peeling mechanism 200.

[0038] Reference Figure 2 and Figure 3 In this embodiment, because the cover film material is relatively long, to avoid insufficient mechanical strength of the excessively long cover film suction cup 121 and the lifting stacking platform 110, the lifting stacking platform 110 is composed of two smaller platforms arranged end to end. The two smaller platforms are driven by two independent stacking platform lifting drive mechanisms 130, and two cover film suction cups 121 are arranged side-by-side on the cover film lifting drive mechanism 122. (Refer to...) Figure 3In this embodiment, the stacking platform lifting drive mechanism 130, the antistatic brush 113, and the air blowing device 114 are all mounted on the lifting base plate 111, which is mounted on the frame. The lifting stacking platform 110 is mounted on the lifting base plate 111 via the corresponding stacking platform lifting drive mechanism 130. Multiple antistatic brushes 113 are arranged side by side on the left and front sides of the lifting stacking platform 110. Multiple grooves are provided on the left side of the lifting stacking platform 110, and an antistatic brush 113 is provided in each groove so that the bristles of the antistatic brush 113 can contact the edge of the cover film material. Meanwhile, the antistatic brush 113 can serve as the left and front guard edges of the cover film material. Multiple adjustable magnetic baffles 115 are provided on the right side of the stacking base plate. Each magnetic baffle 115 has a magnet at its bottom, allowing it to adhere to the stacking base plate for easy adjustment of its position. This adjusts the distance between the magnetic baffles 115 and the antistatic brush 113, enabling pre-positioning of cover film materials of different widths and preventing the cover film material stack from tipping over. The right side of the lifting stacking platform 110 has several equally spaced oblong holes in the width direction through which the magnetic baffles 115 can pass, guiding their placement and limiting their width adjustment stroke. The lifting and stacking platform 110 has a waist-shaped hole in the middle for the movable stop bar 112 to pass through. The lifting base plate 111 has a track in the length direction. The base of the movable stop bar 112 is slidably mounted on the track of the lifting base plate 111 so as to adjust the distance between the movable stop bar 112 and the antistatic brush 113 at the front end, adapt to different lengths of cover film materials, position the cover film materials in the length direction, ensure that the cover film materials can be stably picked up by the cover film suction cup 121, and prevent the cover film materials from being piled up and tilted in the length direction.

[0039] Reference Figures 4 to 8The peeling mechanism 200 includes a peeling platform 210, a swinging pressure roller 220, a swinging drive mechanism 221, a separating pressure roller 230, a separating pressure roller drive mechanism 241, a peeling adhesive roller 240, a peeling adhesive roller lifting drive mechanism 241, a peeling adhesive roller lateral movement drive mechanism 242, a peeling guide channel 250, a peeling fork 260, a peeling fork translation drive mechanism 261, a traction gripper 270, and a traction drive mechanism 271. The peeling platform 210 is horizontally positioned between the cover film feeding mechanism 100 and the receiving platform 300. A first transition roller 211 is rotatably mounted in the middle of the receiving platform 300, and a second transition roller 212 is rotatably mounted at the outlet of the receiving platform 300. Both the first transition roller 211 and the second transition roller 212 can rotate under the drive of a motor. An auxiliary pressure roller 214 is positioned above the first transition roller 211. The auxiliary pressure roller 214 can move up and down under the drive of the auxiliary pressure roller lifting drive mechanism 215 to contact or separate from the first transition roller 211. A peeling and adsorption area 213 is provided on the side of the receiving platform 300 near the second transition roller 212. The peeling and adsorption area 213 can adsorb the release film of the cover film material located above it. Multiple adsorption holes are arrayed in the peeling and adsorption area 213. A cavity communicating with the adsorption holes is provided on the lower side of the peeling and adsorption area. The cavity is connected to a vacuum source. By evacuating the cavity, suction force can be generated at the adsorption holes due to the internal and external pressure difference. The peeling roller 240, the peeling roller lifting drive mechanism 241, and the peeling roller traversing drive mechanism 242 are all arranged above the peeling platform 210. The peeling roller 240 can move up and down under the drive of the peeling roller lifting drive mechanism 241. The peeling roller lifting drive mechanism 241 can reciprocate along the length direction of the cover film material under the drive of the peeling roller traversing drive mechanism 242. The surface of the peeling roller 240 is adhesive. The oscillating pressure roller 220 can press against the first transition roller 211 or the second transition roller 212 under the drive of the oscillating drive mechanism 221. The upper end of the peeling guide channel 250 is located behind the second transition roller 212, and the lower end of the peeling guide channel 250 is located at the entrance of the release film hopper 400. A release film guide roller 253 is rotatably mounted at the lower end of the peeling guide channel 250. The separating pressure roller 230 is located at the entrance of the peeling channel. Under the drive of the separating pressure roller drive mechanism 241, the separating pressure roller 230 can press the front end of the peeled separation film into the peeling guide channel 250. The peeling fork 260 is located behind the second transition roller 212. The height of the peeling fork 260 is flush with the peeling platform 210. Under the drive of the peeling fork translation drive mechanism 261, the peeling fork 260 can reciprocate along the length direction of the cover film material so that the peeling fork 260 can extend between the peeled cover film and the release film.The traction gripper 270 can clamp the front end of the peeled cover film on the peeling fork 260. Driven by the traction drive mechanism 271, the traction gripper 270 can reciprocate along the length of the cover film material to pull the peeled cover film onto the receiving platform 300. The rear end of the peeling fork 260 has a fork-shaped structure to reduce the contact area between the rear end of the peeling fork 260 and the cover film, so that the traction gripper 270 can clamp the front end of the peeled cover film from the peeling fork 260, thereby pulling the cover film onto the receiving platform 300.

[0040] The peeling mechanism 200 and the cover film gripping mechanism 120 feed the front end of the cover film material onto the first transition roller 211 of the peeling platform 210. Then, the auxiliary pressure roller 214 presses down to hold the cover film material in place. Subsequently, the first transition roller 211 rotates, feeding the cover film material backward until the front end of the cover film material moves to the peeling adsorption area 213. The peeling adsorption area 213 then holds the front end of the cover film material, that is, it holds the surface of the release film located below. At the same time, the swing pressure roller 220 swings to the rear side of the first transition roller 211 under the drive of the swing drive mechanism 221, pressing the area between the peeling adsorption area 213 and the first transition roller 211 onto the peeling platform 210. Subsequently, the peeling roller 240, driven by the peeling roller lateral drive mechanism 242 and the peeling roller lifting drive mechanism 241, presses against the cover film material on the peeling adsorption area 213. Due to the adhesiveness of the peeling roller 240, the adhesion between the cover film and the roller on the upper side is greater than the adhesion between the cover film and the release film. The peeling roller 240 then moves towards the first transition roller 211, and in conjunction with the adsorption force of the oscillating pressure roller 220 and the peeling adsorption area 213, it rolls up the front end of the cover film, separating it from the release film. The peeling roller 240 should reciprocate several times on the peeling adsorption area 213 to ensure that the front end of the cover film can be rolled up. Then, the first transition roller 211 continues to rotate, feeding the cover film material backward, while the peeling roller 240 moves backward simultaneously, causing the rolled-up front end of the cover film to pass over the second transition roller 212 and reach the exit of the peeling platform 210. At this time, the oscillating pressure roller 220, driven by the oscillating drive mechanism 221, presses against the second transition roller 212. The front end of the peeled release film extends under the separating pressure roller 230. The peeling fork 260, driven by the peeling fork translation drive mechanism 261, moves towards the peeling platform 210, so that the front end of the peeling fork 260 extends between the separated cover film and the release film. Subsequently, the separating pressure roller 230, driven by the separating pressure roller drive mechanism 241, presses down, pressing the release film into the peeling guide channel 250. The peeling roller 240 moves backward and rises, unfolding the front end of the rolled-up cover film and laying it on the peeling fork 260. Finally, the traction gripper 270 moves to the peeling fork 260, clamps the fork-shaped structure at the rear end of the peeling fork 260, and clamps the front end of the cover film. The traction drive mechanism 271 drives the traction gripper 270 to move backward. At the same time, the first transition roller 211 and the second transition roller 212 rotate synchronously to feed the cover film material backward. While the cover film material moves, under the action of the separating pressure roller 230 and the peeling fork 260, the cover film is separated from the release film. The cover film is pulled onto the receiving platform 300, and the release film flows into the release film hopper 400 below the receiving platform 300 under the guidance of the peeling guide channel 250.

[0041] Reference Figure 4In this embodiment, both the swing drive mechanism 221 and the separation pressure roller drive mechanism 241 consist of a pair of swing arms and a rotary cylinder, with the swing pressure roller 220 and the separation pressure roller 230 rotatably connected to their respective swing arms. (Refer to...) Figure 6 In this embodiment, the peeling roller lifting drive mechanism 241 includes a first lifting drive mechanism 2411 and a second lifting drive mechanism 2412. The first lifting drive mechanism 2411 is driven by a conventional cylinder, and the second lifting drive cylinder is driven by a high-precision slide cylinder. The first lifting drive mechanism 2411 drives a peeling movable support 2413 to move up and down, causing the peeling roller 240 to rise or fall onto the peeling platform 210. The second lifting drive mechanism 2412 is mounted on the peeling movable support 2413. The peeling roller 240 is connected to the slide of the slide cylinder in the second lifting drive mechanism 2412 via a roller support. Both ends of the peeling roller 240 are rotatably connected to the roller support. By using an adjustable proportional valve in conjunction with the high-precision slide cylinder, the pressure between the peeling roller 240 and the cover film can be adjusted, thereby facilitating adjustment and improving the success rate of the peeling roller 240 rolling up the cover film. (Refer to...) Figure 7 The peeling guide channel 250 includes an arc-shaped inner guide plate 251 and an outer baffle 252. A release film guide roller 253 is positioned above the outlet of the inner guide plate 251, and the outer baffle 252 is positioned above the release film guide roller 253. These components block and guide the release film along the peeling guide channel 250. The leading edge of the release film, as the cover film material is fed backward, extends between the release film guide roller 253 and the inner guide plate 251 under the guidance of the peeling guide channel 250. (Refer to...) Figure 9 In this embodiment, to assist in the separation of the release film from the cover film and to facilitate the pulling of the release film into the release film hopper 400, a release film gripper 420 and a release gripper driving mechanism 430 are provided above the release film hopper 400. During peeling, the release film gripper 420 moves to the outlet of the peeling guide channel 250 under the drive of the release gripper driving mechanism 430, grips the front end of the release film, and moves backward synchronously with the traction gripper 270, pulling the release film into the release film hopper 400. To facilitate the removal of the release film from the hopper when it is full, the release film hopper 400 is mounted on the hopper lateral movement driving mechanism 410, and can extend backward below the receiving platform 300 under the drive of the hopper lateral movement driving mechanism 410, so as to remove the release film from the hopper.

[0042] Reference Figure 8In this embodiment, the receiving platform 300 also consists of two small platforms. The adsorption structure of the receiving platform 300 is similar to the peeling adsorption area 213 on the peeling platform 210, achieved by adsorption holes on the platform surface, an internal cavity, and a vacuum source connected to the cavity, which will not be described in detail here. A downwardly curved arc-shaped guide plate is provided at the entrance of the receiving platform 300 to prevent the cover film from getting caught on the edge of the receiving platform 300 when the traction gripper 270 pulls the cover film. The height of the receiving platform 300 should preferably be flush with or slightly lower than the peeling platform 210 to facilitate the traction gripper 270 pulling the cover film onto the receiving platform 300.

[0043] Reference Figure 9 and Figure 10The covering film transport mechanism 500 includes a transport gantry 510 and two sets of transport robotic arms 520. The transport gantry 510 spans above the receiving platform 300 and the bonding platform 700, which are arranged side by side. The two sets of transport robotic arms 520 are symmetrically arranged on both sides of the transport gantry 510. The transport robotic arms 520 include a transport longitudinal movement drive mechanism 525, a transport lifting drive mechanism 524, a transport translation drive mechanism 523, a transport rotation drive mechanism 522, and a transport suction plate 521. The transport suction plate 521 is mounted on the transport rotation drive mechanism 522, the transport rotation drive mechanism 522 is mounted on the transport translation drive mechanism 523, the transport translation drive mechanism 523 is mounted on the transport lifting drive mechanism 524, the transport lifting drive mechanism 524 is mounted on the transport longitudinal movement drive mechanism 525, and the transport longitudinal movement drive mechanism 525 is mounted on the transport gantry 510. The transport adsorption plate 521 can rotate in the horizontal plane under the drive of the transport rotation drive mechanism 522. The transport rotation drive mechanism 522 can reciprocate along the length direction of the cover film under the drive of the transport translation drive mechanism 523. The transport translation drive mechanism 523 can move up and down under the drive of the transport lifting drive mechanism 524. The transport translation drive mechanism 523 can reciprocate along the width direction of the cover film under the drive of the transport longitudinal drive mechanism 525, so that the transport adsorption plate 521 moves back and forth above the receiving platform 300 and the bonding platform 700. The transport adsorption plate 521 has adsorption capacity and can adsorb the upper surface of the cover film. The adsorption structure of the transport adsorption plate 521 is similar to that of the receiving platform 300, and will not be described in detail here. The transport adsorption plate 521 is movably connected to the transport rotation drive mechanism 522 via the adsorption plate fixing seat 5211. The transport adsorption plate 521 can reciprocate relative to the adsorption plate fixing seat 5211 in the vertical direction. Multiple first elastic elements 5213 are provided between the transport adsorption plate 521 and the adsorption fixing seat. The two transport robotic arms 520 can adjust the angle of the transport adsorption plate 521 via the transport rotation drive mechanism 522, thereby facilitating the correction of bending of longer cover films. The two transport robotic arms 520 can also adjust the distance between the two transport adsorption plates 521 via the transport translation drive mechanism 523, thereby accommodating cover films of different lengths and allowing the cover film to be tensioned, further preventing wrinkles. It is understood that the transport rotation drive mechanism 522 can be a torque motor or a DD motor.

[0044] Reference Figure 11In this embodiment, four transport guide rods 5212 are provided on the back side of the transport adsorption plate 521. The adsorption fixing seat is connected to the output shaft of the transport rotation drive mechanism 522. The four feet of the adsorption fixing seat are slidably connected to the four transport guide rods 5212 through four linear bearings, realizing the movable connection between the transport adsorption plate 521 and the adsorption fixing seat. The first elastic element 5213 is preferably a compression spring. Multiple first elastic elements 5213 are symmetrically distributed between the back side of the transport adsorption plate 521 and the adsorption fixing seat, forming a floating structure with the four transport guide rods 5212 to absorb the impact force of the transport adsorption plate 521 from the receiving platform 300, and to facilitate the transport adsorption plate 521 to successfully pick up the cover film from the receiving platform 300. It can be understood that in some embodiments, the transport adsorption plate 521 is provided with a heating device such as an electrothermal resistance to preheat the adsorbed cover film, so that the cover film can better initially adhere to the product.

[0045] Reference Figure 12 In this embodiment, the feeding mechanism 600 includes a feeding shaft 610 for placing product rolls, a waste collection shaft 620 for collecting protective film from the product, a cleaning mechanism 630 for cleaning the product surface, a step mechanism 640 for adjusting tension, and several transition rollers. Both the feeding shaft 610 and the waste collection shaft 620 are motor-driven rotating shafts. The cleaning mechanism 630 consists of a pair of cleaning rollers that adhere to or absorb dust from the product.

[0046] Reference Figures 13 to 16 In this embodiment, the bonding platform 700 includes a fixed platform 710 and a movable adsorption plate 720. A plurality of bonding adsorption areas 7211 are spaced apart on the upper surface of the movable adsorption plate 720, each capable of adsorbing the area of ​​the product to be bonded. The movable adsorption plate 720 has a cavity within which the fixed platform 710 can move, and the fixed platform 710 is disposed within the cavity. The fixed platform 710 is fixedly mounted on a frame, and the movable adsorption plate 720 is movably mounted on the frame via a bonding guide mechanism 730. The movable adsorption plate 720 moves up and down relative to the fixed platform 710 under the guidance of the bonding guide mechanism 730. A plurality of second elastic elements 733 are disposed between the movable adsorption plate 720 and the bonding guide mechanism 730. (Refer to...) Figure 13 and Figure 15In this embodiment, the movable adsorption plate 720 includes an adsorption top plate 721, an air guide block 722, and an adsorption bottom plate 723. The adsorption top plate 721 has multiple adsorption areas 7211 spaced along its length, with adsorption holes arrayed at each adsorption area 7211. The air guide block 722 has an internal cavity, and its upper surface has an array of adsorption holes aligned with the adsorption holes of the adsorption areas 7211. The adsorption holes on the surface of the air guide block 722 communicate with the internal cavity. The adsorption bottom plate 723 is positioned below the adsorption bottom plate 723, and multiple air guide blocks 722 are positioned between the adsorption top plate 721 and the adsorption bottom plate 723, with each air guide block 722 correspondingly positioned below its respective adsorption area 7211. The lower end face of the air guide block 722 is provided with an air guide hole communicating with the cavity. The adsorption base plate 723 is provided with an air passage that can communicate with the air guide hole, and the side of the adsorption base plate 723 is provided with a connector communicating with the air passage. The cavity inside the air guide block 722 is connected to a vacuum source through the air guide hole, air passage and connector, so that the adsorption area 7211 can generate suction. The gap between the air guide blocks 722 forms a cavity for accommodating the fixed platform 710. The fixed platform 710 is provided with multiple clearance holes through which the air guide blocks 722 can pass. The movable adsorption plate 720 is movably mounted on the frame via multiple bonding guide mechanisms 730. Each bonding guide mechanism 730 includes a guide bracket 731 and a pair of bonding guide rods 732. The guide bracket 731 stands below the movable adsorption plate 720, and the bonding guide rods 732 stand on the lower surface of the movable adsorption base plate 723. The guide bracket 731 is slidably connected to the bonding guide rods 732 via linear bearings. Multiple second elastic elements 733 are symmetrically arranged between the adsorption base plate 723 and the guide, forming a floating structure. These second elastic elements 733 are preferably compression springs. Due to the floating structure of the movable adsorption plate 720, under the action of the second elastic elements 733, during the process of the adsorption plate 521 applying the cover film to the product, the product and the cover film are partially tightly bonded, ensuring tight contact even in the bonding adsorption area 7211. This prevents excessive pressure on areas of the product that do not require tight bonding, thus protecting areas to be bonded, such as circuit areas on a circuit board, and improving product yield. (Refer to...) Figure 13 and Figure 14 In this embodiment, to improve the mechanical strength of the platform, the bonding platform 700 is also composed of two sub-platforms arranged end to end. An auxiliary support roller 740 is provided in the gap between the two sub-platforms. The auxiliary support roller 740 can move up and down under the drive of the auxiliary roller lifting drive mechanism 741. During bonding, the auxiliary support roller 740 is lowered below the bonding platform 700 to avoid affecting the bonding. After bonding is completed, the auxiliary support roller 740 is raised to slightly above the bonding platform 700 to reduce friction between the product and the bonding platform 700 during product movement, making the product conveyor belt move more smoothly.

[0047] Reference Figure 17 In this embodiment, the hot pressing mechanism 800 includes an upper module 810, a lower module 820, a pressing drive mechanism 830, and an auxiliary material pulling mechanism. The upper module 810 and the lower module 820 can approach or separate under the drive of the pressing drive mechanism 830. The auxiliary material pulling mechanism includes an auxiliary material pulling gripper 840 and an auxiliary material pulling drive mechanism 841. The auxiliary material pulling gripper 840 can reciprocate along the length direction of the product under the drive of the auxiliary material pulling drive mechanism 841 to assist the product in passing between the upper module 810 and the lower module 820. It is understood that the upper module 810, from bottom to top, includes an upper pressing panel, an upper heating plate, an upper heat insulation plate, and an upper connecting plate. Correspondingly, the lower module 820, from top to bottom, includes a lower pressing panel, a lower heating plate, a lower heat insulation plate, and a lower connecting plate. Heating devices such as thermal resistors are installed inside the upper and lower heating plates. The upper and lower heat insulation plates are made of heat-insulating material to prevent heat generated by the heating plates from being transferred to other structures. In this embodiment, the pressing drive mechanism 830 includes an upper pressing drive mechanism 831 and a lower pressing drive mechanism 832. The upper module 810 and the lower module 820 can respectively move up and down under the drive of the upper pressing drive mechanism 831 and the lower pressing drive mechanism 832, thereby allowing the pressure of the upper module 810 and the lower module 820 to be independently adjustable. The upper module 810 and the lower module 820 are connected to the upper pressing drive mechanism 831 and the lower pressing drive mechanism 832 respectively through the upper connecting plate and the lower connecting plate.

[0048] Reference Figure 1 In this embodiment, to further improve the bonding quality of the cover film and the bonding accuracy between the cover film and the product, the device also includes a lower photographing mechanism 1000 and an upper photographing mechanism 1100. The lower photographing mechanism 1000 is located below the cover film transport mechanism 500 and is used to photograph the cover film on the cover film transport mechanism 500. The upper photographing mechanism 1100 is located above the bonding platform 700 and is used to photograph the product on the bonding platform 700. By photographing the lower surface of the cover film and the upper surface of the product, the lower photographing mechanism 1000 and the upper photographing mechanism 1100 position the cover film and the product using the markings on the cover film and the product, thereby controlling the cover film transport mechanism 500 to accurately bond the cover film to the product.

[0049] Reference Figure 8In this embodiment, the lower camera mechanism 1000 includes two lower camera modules 1020 and a dual-motion sub-platform 1010. The lower camera modules 1020 are respectively disposed on two sliders of the dual-motion sub-platform 1010. The dual-motion sub-platform 1010 is disposed between the receiving platform 300 and the bonding platform 700 along the length direction of the cover film. The dual-motion sub-platform 1010 can control the two lower camera modules 1020 to take pictures of both ends of the cover film on the cover film transport mechanism 500, and simultaneously position the cover film. It also determines whether the cover film is bent or wrinkled by the angle and spacing between the two ends of the cover film. Furthermore, it controls the transport rotation drive mechanism 522 of the two transport robotic arms 520 to rotate the transport suction plate 521 to correct the bending of the cover film, and controls the transport translation drive mechanism 523 of the two transport robotic arms 520 to adjust the spacing between the transport suction plates 521 to tension the cover film. (Refer to...) Figure 13 and Figure 16 In this embodiment, the upper imaging mechanism 1100 includes an upper imaging gantry 1110, two upper camera modules 1130, and an imaging transverse drive mechanism 1120. The upper imaging gantry 1110 spans above the bonding platform 700, and the two upper camera modules 1130 are symmetrically arranged side-by-side on the upper imaging gantry 1110. The upper imaging gantry 1110 can reciprocate along the length of the product under the drive of the imaging transverse drive mechanism 1120. The upper imaging mechanism 1100 can achieve complete coverage of the width of the product through the two side-by-side upper camera modules 1130. After the product is bonded, the two upper cameras can also take pictures of the initially bonded product to check the bonding effect. It is understood that the lower camera module 1020 and the upper camera module 1130 typically include a light source, camera lens, and necessary support structure, etc., and their specific structures are common knowledge in the art and will not be described in detail here.

[0050] Reference Figure 18In this embodiment, the take-up mechanism 900 includes at least one take-up shaft 910, which is a self-rotating drive shaft driven by a motor. It is used to hold an empty roll. By attaching the front end of the product roll to the empty roll, and by driving the take-up shaft 910 to rotate to pull the product, the product, after being falsely attached, is wound onto the take-up shaft 910, thus taking the product into a roll. It is understood that multiple transition rollers are provided on the product's conveyor path to guide the product along a preset conveyor path. It is also understood that the aforementioned linear drive mechanisms for translation, lifting, or longitudinal movement, such as the cover film lifting drive mechanism 122, the cover film translation drive mechanism 123, and the stacking platform lifting drive mechanism 130, can all be linear drive mechanisms composed of drive devices such as motors or cylinders, transmission mechanisms such as lead screw pairs or synchronous pulley sets, and guide structures such as slide rails or guide rods. The traction gripper 270, release film gripper 420, and other grippers can all be composed of a combination of a finger-gripping cylinder or a general-purpose cylinder and a guide rod, as well as a clamping structure such as a clamping plate or a finger-gripping mechanism. The specific structures of these components are common knowledge in the field and will not be elaborated here. The positional information of the cover film raw material, cover film, release film, and product in the equipment, such as their placement and stacking height, can be obtained through corresponding photoelectric switches, through-beam sensors, or light sensors at various points on the equipment.
