Description

Technical Field

[0001] This invention belongs to the field of back panel tape application technology, and particularly relates to a continuous tape application processing device for notebook computer back panels. Background Technology

[0002] As the consumer electronics industry moves towards thinner, lighter, and more integrated designs, the structure of laptop back panels is becoming increasingly complex, often featuring irregular contours such as micro-arc surfaces, reinforcing rib grooves, screw post clearances, and edge step differences. During the back panel manufacturing process, functional tapes are typically applied to achieve structural bonding, sealing, or electromagnetic shielding. The flatness and adhesion strength of these tapes directly affect the final reliability of the product.

[0003] Currently, tape application in the industry mainly adopts two methods: manual application and semi-automatic equipment application. Manual application is inefficient and inconsistent, making it difficult to meet the needs of mass production. Conventional semi-automatic application equipment mostly adopts a single-roller rigid pressing structure, which directly presses the tape onto the surface of the workpiece, but has many shortcomings in practical applications.

[0004] First, during the bonding process between the tape and the substrate, residual air is easily trapped at the interface, forming bubbles or local hollow areas, resulting in insufficient effective bonding area. After long-term use, problems such as tape lifting and falling off are likely to occur. Existing solutions optimize the pressing effect by increasing the number of pressure rollers, but most of them are parallel straight roller structures, which cannot directionally drive out the air at the interface, and the air exhaust effect is limited.

[0005] Secondly, conventional pressing structures often have a rigid and fixed pressing surface, which makes it difficult to adapt to the slight undulations and irregular contours of the backing surface. This can easily lead to uneven local pressure, incomplete pressing in the corner areas, and poor overall adhesion. Some improved solutions using flexible pressing heads can adapt to the contours to a certain extent, but the uneven distribution of pressing force still cannot solve the problem of air venting at the interface.

[0006] Furthermore, relying solely on conventional rolling for compaction often fails to achieve the desired bonding strength for high-viscosity, thick functional tapes, resulting in limited improvement in the adhesion between the tape and the substrate, which is insufficient to meet the durability requirements of high-end electronic products. On the other hand, external vibration compaction structures occupy additional working space and can easily cause axial displacement of the tape, affecting the application quality.

[0007] There is an urgent need for improvement, so we propose a continuous tape application auxiliary process for notebook back panels. Summary of the Invention

[0008] The purpose of this invention is to address the aforementioned technical problems by providing a continuous tape application processing device for notebook computer back panels.

[0009] In view of this, the present invention provides a continuous tape application processing device for notebook computer back panels, comprising: A tape applicator includes a frame body and a rolling mechanism mounted on the frame body. The rolling mechanism includes a cylinder, a universal joint mounted on the cylinder drive end, and an exhaust and compaction assembly mounted on the bottom end of the universal joint. The exhaust compaction assembly includes a frame portion fixed to the bottom of the mounting plate. The frame portion includes a rectangular frame and a V-shaped connecting frame fixed to one end of the rectangular frame in the direction of movement. A compaction roller for compacting the adhesive tape is rotatably connected to the inner cavity of the rectangular frame. Connecting grooves are provided on both sides of the bottom end of the connecting frame. An exhaust roller for pre-pressing the adhesive tape and venting air from the bonding interface is rotatably connected in each connecting groove.

[0010] Furthermore, it also includes a compaction auxiliary mechanism, which includes a drive assembly mounted on one side of the rectangular frame, a sleeve coaxially fixed to one end of the compaction roller near the drive assembly, and a connecting shaft coaxially fixed to the other end of the compaction roller. The end of the connecting shaft away from the compaction roller is rotatably connected to the inner cavity of the rectangular frame. The compaction roller has a hollow cavity structure. The end of the sleeve near the compaction roller is connected to the inner cavity of the compaction roller, and the other end of the sleeve is rotatably inserted through the side wall of the rectangular frame. The inner cavity of the compaction roller is provided with an excitation assembly for generating eccentric excitation force. The drive end of the drive assembly passes through the inner cavity of the sleeve and is drively connected to one end of the excitation assembly to drive the excitation assembly to operate, so that the compaction roller generates radial vibration.

[0011] Furthermore, the excitation assembly includes gear disks symmetrically arranged on both sides of the inner cavity of the compaction roller, and rotating shafts symmetrically arranged on both sides of the two gear disks. The two ends of each rotating shaft are rotatably supported on the two end walls of the inner cavity of the compaction roller. A transmission shaft is coaxially fixed between the two gear disks. Driven gears are symmetrically fixed on both sides of the outer peripheral wall of each rotating shaft. The two driven gears on the same side mesh with the corresponding gear disks on the same side for transmission. Eccentric weights are also symmetrically fixed on both sides of the outer peripheral wall of each rotating shaft. The two eccentric weights on the same side are located on the outer peripheral wall of the rotating shaft between the two driven gears on the same side. The eccentric orientations of the eccentric weights on the two rotating shafts are opposite.

[0012] Furthermore, the drive assembly includes a mounting bracket fixed to the outer end wall of the rectangular frame and a drive motor mounted on the mounting bracket. The drive end of the drive motor is connected to a drive shaft via a coupling. The drive shaft rotatably passes through the inner cavity of the sleeve and is coaxially and fixedly connected to one of the gear discs.

[0013] Furthermore, the universal assembly includes a base fixed to the cylinder drive end, with connecting rod assemblies hinged to both sides of one end of the base via hinge assemblies, and mounting plates hinged to the other ends of each connecting rod assembly via universal joints. The connecting rod assembly includes a sleeve and a piston slidably fitted into the inner cavity of the sleeve. A rod body is coaxially fixed to one end of the piston, and one end of the rod body extends to the outside of the sleeve.

[0014] Furthermore, the hinge assembly includes mounting seats symmetrically fixed to both sides of the bottom end of the base, and the sleeve is rotatably mounted on the inner side of the mounting seats on both sides via a pin.

[0015] Furthermore, the universal joint includes ball grooves symmetrically opened on both sides of the mounting plate surface, and a universal ball is rotatably embedded in each ball groove. The ends of the two rods away from the piston are fixedly connected to the corresponding universal balls.

[0016] Furthermore, the piston has multiple air holes that penetrate its thickness direction at equal intervals along its circumference, a return spring is fixed between the base and the middle of the mounting plate, a guide sleeve is fixed inside the opening end of the sleeve, and the rod body is slidably fitted inside the guide sleeve.

[0017] Furthermore, the center of the ball groove is located inside the mounting plate, and the center-to-center distance between the two ball grooves is less than the center-to-center distance between the two mounting bases.

[0018] Furthermore, the tape applicator also includes a tape unwinding and supply mechanism, a tape feeding and guiding mechanism, a mounting shaft fixed to the top of the frame body, and a cutting mechanism located at the rear end of the frame body.

[0019] The beneficial effects of this invention are: It can achieve adaptive venting continuous pressing operation on the laptop back panel by setting up cylinders, universal components and venting and compaction components. At the same time, the front V-shaped double venting rollers drive away residual air at the bonding interface from the center to both sides of the pre-pressing trajectory, and the rear compaction rollers follow up to compact and shape the whole surface. This achieves source control of air bubbles and air bulges and uniform pressure distribution on the whole surface, effectively avoiding the problems of tape lifting and falling off in the later stage, and improving the bonding quality and bonding reliability of complex contour back panels. It can also drive the built-in vibration component to generate radial micro-vibration through the compaction auxiliary mechanism, and simultaneously superimpose the compaction effect of the adhesive layer on the basis of conventional rolling, ensuring that the high viscosity and thick tape are tightly bonded to the substrate. At the same time, with the adaptive extension and contraction characteristics of the universal component, it moves down and fills the gap in real time as the adhesive layer is compacted and thinned, maintaining a stable pressing force throughout the process without the need for manual adjustment of the stroke, effectively improving the bonding strength and continuous stability of the application operation. Alternatively, an integrated excitation structure with dual-shaft reverse eccentric counterweight and gear meshing transmission can be used to maintain directional radial excitation output during the continuous rolling of the compaction roller, avoiding tape offset and reduced adhesion quality caused by axial movement.

[0027] Reference Figures 1 to 9 A continuous tape application processing device for notebook computer back panels, comprising: The tape applicator 100 includes a frame body 101 and a rolling mechanism 105 disposed on the frame body 101. The rolling mechanism 105 includes a cylinder 107, a universal assembly disposed on the drive end of the cylinder 107, and an exhaust and compaction assembly disposed on the bottom end of the universal assembly. The exhaust compaction assembly includes a frame portion 300 fixed to the bottom end of the mounting plate 206. The frame portion 300 includes a rectangular frame 301 and a V-shaped connecting frame 302 fixed to one end of the rectangular frame 301 in the direction of movement. A compaction roller 600 for compacting adhesive tape is rotatably connected to the inner cavity of the rectangular frame 301. Connecting grooves 400 are provided on both sides of the bottom end of the connecting frame 302. An exhaust roller 401 for pre-pressing the adhesive tape and venting air from the bonding interface is rotatably connected in each of the connecting grooves 400.

[0028] This application achieves adaptive venting continuous pressing in the application of tape to a laptop back panel by using a cylinder 107, a universal joint, and a venting and compaction component. During actual operation, the cylinder 107 outputs a stable downward pressing force, and the universal joint drives the venting and compaction component at the bottom to adjust the bonding angle in real time according to the slight undulations of the back panel surface. This overcomes the limitation of traditional rigid pressure heads being unable to adapt to irregular contours. The venting and compaction component adopts a front-mounted V-shaped double venting roller 401 and a rear-mounted single compaction roller 600 arrangement. As the tape travels in the bonding direction, the exhaust rollers 401 on both sides of the V-shaped connecting frame 302 first contact the tape. With a pre-pressure trajectory that gradually extends from the center to both sides, the air trapped between the tape and the substrate interface is continuously driven outward, thereby reducing the generation of air bubbles and voids and ensuring effective bonding area. The compaction roller 600 that follows then compacts and shapes the entire tape, which not only improves the uniformity of the bonding pressure on the entire surface, but also effectively avoids the problem of tape lifting and falling off later, adapting to the bonding needs of various back panels with different structures.

[0029] In the example of this application, a compaction auxiliary mechanism is also included. The compaction auxiliary mechanism includes a drive assembly mounted on one side of the rectangular frame 301, a sleeve 602 coaxially fixed to the end of the compaction roller 600 near the drive assembly, and a connecting shaft 601 coaxially fixed to the other end of the compaction roller 600. The end of the connecting shaft 601 away from the compaction roller 600 is rotatably connected to the inner cavity of the rectangular frame 301. The compaction roller 600 has a hollow cavity structure. The end of the sleeve 602 near the compaction roller 600 is connected to the inner cavity of the compaction roller 600. The other end of the sleeve 602 is rotatably inserted through the side wall of the rectangular frame 301. The inner cavity of the compaction roller 600 is provided with an excitation assembly for generating eccentric excitation force. The drive end of the drive assembly passes through the inner cavity of the sleeve 602 and is drively connected to one end of the excitation assembly to drive the excitation assembly to operate, so that the compaction roller 600 generates radial vibration.

[0030] As a preferred example of the present invention, the vibration compaction function is integrated into the compaction roller 600 by adding a compaction auxiliary mechanism. This superimposes a radial micro-vibration effect on top of conventional rolling, specifically addressing the problem of insufficient bonding strength for high-viscosity, thick-film adhesive tapes. During operation, the drive component transmits power to the compaction roller 600 through the inner cavity of the sleeve 602, driving the excitation component in the cavity to generate an eccentric excitation force. This causes the compaction roller 600 to generate high-frequency radial micro-vibration while maintaining rolling compaction. The vibration energy is transmitted to the bonding interface through the roller body, and the high-frequency micro-vibration compacts the adhesive layer of the tape, allowing the tape and substrate to adhere more tightly. This effectively eliminates tiny gaps between the interfaces, ultimately resulting in a tighter bond and significantly improving bonding strength and long-term reliability. With the adaptive telescopic characteristics of the upper universal component, the compaction roller 600 can move down synchronously in real time to fill the gap as the tape is vibrated and compacted and its thickness is slightly reduced. This ensures that the roller body is always in close contact with the tape surface and there will be no pressure attenuation or local suspension due to the thinning of the adhesive layer. This makes the vibration compaction effect stable and controllable throughout the process. At the same time, this structure integrates the vibration unit into the roller body cavity, without occupying additional external working space. It can be fully adapted to the continuous bonding production rhythm and meet the durability requirements of high-end electronic products.

[0031] In the example of this application, the excitation assembly includes gear disks 605 symmetrically arranged on both sides of the inner cavity of the compaction roller 600, and rotating shafts 603 symmetrically arranged on both sides of the two gear disks 605. The two ends of each rotating shaft 603 are rotatably supported on the two end walls of the inner cavity of the compaction roller 600. A transmission shaft 607 is coaxially fixed between the two gear disks 605. Driven gears 606 are symmetrically fixed on both sides of the outer peripheral wall of each rotating shaft 603. The two driven gears 606 on the same side mesh with the corresponding gear disks 605 on the same side for transmission. Eccentric weights 604 are also symmetrically fixed on both sides of the outer peripheral wall of each rotating shaft 603. The two eccentric weights 604 on the same side are located on the outer peripheral wall of the rotating shaft 603 between the two driven gears 606 on the same side. The eccentric orientations of the eccentric weights 604 on the two rotating shafts 603 are opposite.

[0032] As a preferred example of the present invention, the vibration assembly adopts a gear transmission combined with a dual-shaft reverse eccentric counterweight structure to achieve directional and stable radial vibration output. During operation, the transmission shaft 607 drives the two gear disks 605 to rotate synchronously. After being meshed and transmitted by the driven gear 606, the two rotating shafts 603 rotate synchronously at the same speed. Since the eccentric weights 604 on the two rotating shafts 603 are eccentrically oriented in opposite directions, the axial vibration components generated by the two sets of eccentric weights 604 during rotation will cancel each other out, retaining only the radial vibration energy perpendicular to the tape bonding surface. This avoids the problems of tape offset and reduced bonding quality caused by the axial movement of the roller, and also allows the vibration energy to act more concentrated on the bonding interface, resulting in higher compaction efficiency. At the same time, the symmetrical gear transmission structure operates smoothly with low noise and ensures transmission synchronization, which can support stable operation for long-term continuous production.

[0033] In the example of this application, the drive assembly includes a mounting bracket 502 fixed to the outer end wall of the rectangular frame 301 and a drive motor 501 mounted on the mounting bracket 502. The drive end of the drive motor 501 is connected to a drive shaft 500 via a coupling. The drive shaft 500 rotatably passes through the inner cavity of the sleeve 602 and is coaxially and fixedly connected to one of the gear disks 605.

[0034] As a preferred example of the present invention, the drive motor 501 is fixed to the outside of the rectangular frame 301 by the mounting bracket 502. The power is directly transmitted to the inside of the compaction roller 600 and connected to the gear disk 605 via the coupling and drive shaft 500. The transmission path is short and the power loss is small. The design of placing the motor body externally makes the later inspection and maintenance more convenient. The motor can be debugged and replaced without disassembling the sealed cavity of the compaction roller 600.

[0035] It should be noted that the inner diameter of the sleeve 602 is larger than the outer diameter of the drive shaft 500, and an annular assembly gap is left between the shaft walls of the two to achieve the non-interference operation of the two independent rotating units: the drive shaft 500 passes through the inner cavity of the sleeve 602, and its end is directly connected to the excitation component inside the compaction roller 600, and it rotates independently to output excitation force; the sleeve 602 is coaxially fixed to the end of the compaction roller 600, and rotates together with the compaction roller 600 along the attachment direction to complete the rolling operation. The two rotate without contact or friction interference throughout the entire process, which can avoid the operation of the drive shaft 500 from affecting the normal rotation of the compaction roller 600, and ensure that the rolling attachment and radial vibration compaction functions operate independently and stably without weakening the operation effect.

[0036] Furthermore, the rotational speed of the eccentric weight 604 is significantly greater than the rotational speed of the compaction roller 600. Since the drive shaft 500 and the sleeve 602 are two independent transmission structures, their rotational speeds do not interfere with each other. Therefore, the operating speed of the eccentric weight 604 can be increased independently by adjusting the output speed of the drive component. This speed difference design allows the compaction roller 600 to generate high-frequency radial micro-vibrations, ensuring that during the continuous travel and application process of the equipment, the tape per unit length can be subjected to sufficient vibration and compaction, fully compacting the adhesive layer and eliminating fine gaps at the interface.

[0037] In the example of this application, the universal assembly includes a base 200 fixed to the drive end of the cylinder 107. One end of the base 200 is hinged to two sides by a hinge assembly, and the other end of each of the connecting rod assemblies is hinged to a mounting plate 206 by a universal joint. The connecting rod assembly includes a sleeve 203 and a piston 208 that slides within the cavity of the sleeve 203. One end of the piston 208 is coaxially fixed to a rod body 204, and one end of the rod body 204 extends to the outside of the sleeve 203.

[0038] As a preferred example of the present invention, two sets of connecting rod assemblies are symmetrically hinged below the base 200. Each set of connecting rods adopts a telescopic structure of sleeve 203 and sliding piston 208. The bottom end is connected to the mounting plate 206 through a universal joint. When there are undulations or curved surfaces of different angles on the back plate surface, the length of the connecting rods on both sides can be adjusted autonomously by the sliding of the piston 208 in the sleeve 203. With the hinge and universal rotation structure at the upper and lower ends, the mounting plate 206 is driven to adjust the tilt angle and bonding posture in real time, ensuring that the exhaust roller 401 and the compaction roller 600 are always bonded to the tape surface with uniform pressure, and there will be no situation of local incomplete pressing or excessive local pressure. At the same time, the symmetrical support structure of the double connecting rods is more evenly stressed, which can evenly distribute the downward pressure of the cylinder 107 to the entire compaction assembly, resulting in stronger operational stability.

[0039] In the example of this application, the hinge assembly includes mounting seats 201 symmetrically fixed to both sides of the bottom end of the base 200, and the sleeve 203 is rotatably mounted on the inner side of the mounting seats 201 on both sides via a pin.

[0040] As a preferred example of the present invention, the sleeve 203 is mounted between the two mounting seats 201 by means of a pin. It has a small rotation gap and smooth swing, which can support the connecting rod assembly to deflect freely in the vertical plane. It perfectly adapts to the posture adjustment requirements of the longitudinal undulation of the workpiece surface. The symmetrically arranged mounting seats 201 are fixed at the bottom of the base 200, which provides a unified installation benchmark for the connecting rods on both sides. It can ensure that the swing amplitude and force state of the connecting rods on both sides are always kept in sync, and avoid the problem of skewed force and insufficient pressure on one side of the compaction assembly.

[0041] In the example of this application, the universal joint includes ball grooves 207 symmetrically opened on both sides of the mounting plate 206, and a universal ball 205 is rotatably embedded in each ball groove 207. The ends of the two rods 204 away from the piston 208 are fixedly connected to the corresponding universal ball 205.

[0042] As a preferred example of the present invention, the universal ball 205 is embedded in the ball groove 207 of the mounting plate 206, which can achieve multi-directional rotation without dead angles. With the swing structure of the top connecting rod, the exhaust compaction component can adapt to the longitudinal and transverse undulations of the back plate surface at the same time, which can ensure that the roller body and the tape are fully in contact and there will be no local suspension. At the same time, the embedded installation method of the ball groove 207 is stable and the universal ball 205 rotates smoothly without jamming. While transmitting downward pressure, it can smoothly complete the posture adjustment, avoiding the local stress concentration caused by rigid connection and reducing the jamming and sticking problems during the posture adjustment process.

[0043] In the example of this application, the piston 208 is provided with a plurality of air holes 209 that penetrate its thickness direction at equal intervals along its circumference, a return spring 202 is fixed between the base 200 and the middle part of the mounting plate 206, a guide sleeve 210 is fixed inside the opening end of the sleeve 203, and the rod 204 is slidably fitted inside the guide sleeve 210.

[0044] As a preferred example of the present invention, the air holes 209 circumferentially opened by the piston 208 can connect the air on both sides of the inner cavity of the sleeve 203, avoiding the formation of air resistance when the piston 208 slides, making the extension and retraction adjustment of the connecting rod smoother and preventing jamming or lag. The return spring 202 between the base 200 and the mounting plate 206 can, on the one hand, play a buffering role during the attachment process, making the pressing force more gentle and avoiding damage to the back plate or tape by hard pressure. On the other hand, after the undulations on the workpiece surface disappear, it can drive the mounting plate 206 to quickly return to the reference posture, improving the adaptation efficiency of continuous operation. The guide sleeve 210 at the opening of the sleeve 203 provides sliding guidance for the rod 204, preventing radial wobble when the rod 204 extends and retracts, ensuring the straightness of the connecting rod transmission, and making the pressure transmission more stable.

[0045] In the example of this application, the center of the ball groove 207 is located inside the mounting plate 206, and the center distance between the two ball grooves 207 is smaller than the center distance between the two mounting bases 201.

[0046] As a preferred example of the present invention, the center of the ball groove 207 is set inside the mounting plate 206, and the center distance between the two ball grooves 207 is smaller than the center distance between the top mounting base 201, forming an inward-retracting linkage layout that is wider at the top and narrower at the bottom. This layout allows the downward pressure of the two connecting rods to converge towards the central area of ​​the mounting plate 206, ensuring sufficient pressure in the middle area of ​​the compaction roller 600 and avoiding the problem of normal pressure at both ends of the roller body but incomplete compaction in the middle. The design of the ball core being concealed also improves the installation firmness of the universal ball 205, preventing it from coming off under heavy loads. Combined with the inward-retracting linkage structure, the mounting plate 206 has more flexible attitude deflection, more balanced force distribution, and stronger adaptability to complex contour backplates.

[0047] In the example of this application, the tape applicator 100 further includes a tape unwinding and supply mechanism 102, a tape feeding and guiding mechanism 103, a mounting shaft 106 fixed to the top of the frame body 101, and a cutting mechanism 104 disposed at the rear end of the frame body 101.

[0048] As a preferred example of the present invention, the entire machine is mounted and fixed to the corresponding workstation on the production line via the mounting shaft 106 at the top of the main frame 101. The notebook back panel to be processed is moved along with the tooling to the bonding station for positioning. The tape roll is mounted on the tape unwinding supply mechanism 102, and the tape end is pulled by the guide roller group of the tape feeding guide mechanism 103 to the bonding start position below the rolling mechanism 105. Subsequently, the tape unwinding supply mechanism 102 unwinds at a uniform speed and continuously outputs the tape material. The tape is conveyed to the work area along the path of the tape feeding guide mechanism 103, so that the tape enters the rolling work area and matches the rhythm of the subsequent degassing and compaction operation. When the tape reaches the preset length endpoint, the cutting mechanism 104 at the rear of the frame cuts the tape, completing the tape application for a single back panel. Subsequently, the rolling mechanism 105 lifts and the machine head resets. After the next notebook back panel is in place, the above process is repeated to achieve uninterrupted continuous production. Furthermore, the tape unwinding and supply mechanism 102, the tape feeding and guiding mechanism 103, the mounting shaft 106, and the cutting mechanism 104 used in this solution are all existing mature structures in the field of tape application equipment. Their specific structure, working principle, and control method are common knowledge to those skilled in the art, so they will not be described in detail here.

[0049] It should be noted that the bottom end of the compaction roller 600 is coplanar with the bottom ends of the two exhaust rollers 401, and the lowest pressing surfaces of the three are on the same horizontal plane. This ensures that the pre-pressing depth of the exhaust roller 401 and the final pressing depth of the compaction roller 600 are consistent during the rolling operation, avoiding the problem of insufficient pre-pressing venting pressure or excessive pressing during the compaction stage due to the height difference of the rollers. This ensures a smooth connection between the pre-pressing venting and the final pressing and shaping pressure, further improving the flatness of the tape adhesion and the consistency of the pressure on the entire surface.

[0050] Meanwhile, according to the actual application requirements, a weight block 700 can be added to the end of the rectangular frame 301 away from the drive component to balance the weight of the motor, mounting bracket 502 and other components on the drive component side, offset the weight offset caused by the single-sided drive layout, so that the pressing force of the compaction roller 600 is evenly distributed along the axial direction, and avoids the problems of uneven pressure at both ends of the roller body and insufficient adhesion of the tape on one side.

[0051] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
