Description

Technical Field

[0001] This application belongs to the technical field of printed circuit board production, and particularly relates to a copper clad laminate film peeling device. Background Art

[0002] When producing printed circuit boards, a layer of photoresist film needs to be covered on the copper clad laminate as a mask layer for subsequent pattern transfer. Generally, a hot press is used to uniformly press the film on the surface of the copper clad laminate, and then exposure and development are carried out to complete the pattern transfer. After the photoresist film is cured, it still has a certain flexibility and film-forming property and is not completely embrittled. At this time, the film needs to be peeled off the copper clad laminate to expose the complete circuit. During mass production, generally, an operator picks up the film layer from the edge of the copper plate and gradually tears off the whole photoresist film by using the continuity and toughness of the cured film. However, the manual film tearing method is time-consuming and laborious, which is not conducive to improving the production efficiency of printed circuit boards. Summary of the Invention

[0003] In order to solve the above deficiencies of the prior art, this application provides a copper clad laminate film peeling device, which can automatically and continuously peel the copper clad laminate film, effectively improving the production efficiency of printed circuit boards.

[0004] In order to achieve the above purpose, the present invention adopts the following technologies: A copper clad laminate film peeling device, comprising: A conveyor belt, on the outer side of which strip-shaped blocks are arranged in an array along its contour for abutting against the front and rear ends of the copper clad laminate; At least two driving wheels for tensioning the conveyor belt in the horizontal direction. When the conveyor belt is in a tensioned state, the strip-shaped blocks are arranged along the axis direction of the driving wheels; A first mating plate, vertically arranged above the conveyor belt and facing the axis direction of the driving wheels, and the first mating plate is movably arranged in the vertical direction; A second mating plate, arranged parallel to the first mating plate and movably arranged in the vertical direction. The first mating plate and the second mating plate are arranged along the conveying direction of the conveyor belt. A plurality of suction cups are arranged at the bottom of the second mating plate along its length direction for sucking the film; A mating rod, horizontally mounted above the conveyor belt, the axis of the mating rod being parallel to the axis of the driving wheel, and the mating rod is movably arranged along the conveying direction of the conveyor belt and its reverse direction for entering between the film and the copper clad laminate, peeling the film from the copper clad laminate and straightening the film between the mating rod and the suction cups into a horizontal state; the mating rod is movably arranged in the vertical direction for pushing the strip-shaped blocks and cooperating with the conveyor belt to convey the copper clad laminate; A waste discharging mechanism, comprising a rotating rod vertically arranged on one side of the conveyor belt, the rotating rod being rotatably arranged around its own axis. The upper end of the rotating rod is connected with a horizontally arranged cross plate, and a clamping part is arranged at the end of the cross plate for clamping the film in a straightened state between the mating rod and the suction cups and discharging waste in cooperation with the rotation of the rotating shaft.

[0005] The beneficial effects of the present invention are as follows: 1. Through the settings of the first mating plate, the second mating plate and the suction cup, the film at the front edge of the copper clad laminate can be adsorbed and lifted, and the first mating plate is pressed against the copper clad laminate to quickly separate the film from the copper clad laminate. At the same time, the first mating plate can effectively prevent the film from warping and causing incomplete film peeling, effectively improving the production efficiency of the printed circuit board; 2. The mating rod can not only continuously peel the film, but also straighten the film between the mating rod and the suction cup into a horizontal state, making the film present a definite posture, so as to facilitate the clamping of the clamping part in the waste discharging mechanism. At the same time, the mating rod after the film peeling is completed can also serve as the power source for the operation of the conveyor belt to realize continuous feeding and discharging.

Detailed implementation manners

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will describe the implementation manners of the present invention in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Embodiment 1 The embodiment of the present application provides a copper clad laminate film peeling device, as Figures 1 to 8 shown, including: a drive belt 1, a drive wheel 3, a first mating plate 4, a second mating plate 5, a mating rod 6, a waste discharging mechanism 7, etc.

[0019] Among them, as Figure 1 and Figure 2 shown, in this embodiment, the drive belt 1 is a synchronous belt, the drive wheel 3 is a synchronous wheel. There are three drive wheels 3 which are arranged in parallel with each other. The plane formed by the axes of the three drive wheels 3 is always in a horizontal state. Each drive wheel 3 rotates unidirectionally and in the same direction around its own axis. The two synchronous wheels on both sides tension the synchronous belt horizontally and mesh with the synchronous belt for transmission. The middle synchronous wheel meshes with the synchronous belt and provides support, so that the drive belt 1 is tensioned in a horizontal state. Correspondingly, a tensioning mechanism can be additionally provided to ensure the horizontal tension and load-bearing capacity of the drive belt 1. Using a synchronous belt for the drive belt 1 and synchronous wheels for the drive wheels 3 can ensure the transmission efficiency between the drive belt 1 and the drive wheels 3 and avoid slipping between the drive belt 1 and the drive wheels 3.

[0020] As Figure 1 and Figure 2As shown in the figure, strip blocks 11 are arranged in an array along the outer side of the conveyor belt 1 along its contour. When the conveyor belt 1 is in a tensioned state, the strip blocks 11 are arranged along the axis direction of the driving wheel 3. The distance between two adjacent strip blocks 11 on the horizontal part of the conveyor belt 1 is equal to the length of the copper clad laminate 2, and is used to abut against the front and rear ends of the copper clad laminate 2; on both sides between two adjacent strip blocks 11, there are side retaining strips 12, and the distance between the two side retaining strips 12 is equal to the width of the copper clad laminate 2, and is used to abut against both sides of the copper clad laminate 2. During the movement of the conveyor belt 1, the strip blocks 11 and the side retaining strips 12 can effectively limit the copper clad laminate 2, and can effectively prevent the copper clad laminate 2 from shifting, so as to facilitate subsequent film peeling and film tearing operations.

[0021] As Figures 1 to 4 shown in the figure, the first fitting plate 4 is vertically arranged above the conveyor belt 1 and is arranged towards the axis direction of the driving wheel 3. The first fitting plate 4 is arranged to move vertically, and its lower end is used to press down the copper clad laminate 2; the second fitting plate 5 is arranged parallel to the first fitting plate 4 and is arranged to move vertically. The first fitting plate 4 and the second fitting plate 5 are arranged along the conveying direction of the conveyor belt 1. At the bottom of the second fitting plate 5, there are a plurality of suction cups 51 arranged along its length direction. The arrangement length of the suction cups 51 is consistent with the width of the copper clad laminate 2, and is used to suck the film.

[0022] As Figures 1 to 3 shown in the figure, the fitting rod 6 is horizontally mounted above the conveyor belt 1. The axis of the fitting rod 6 is arranged parallel to the axis of the driving wheel 3. The fitting rod 6 is arranged to move along the conveying direction of the conveyor belt 1 and its reverse direction, and is used to enter between the film and the copper clad laminate 2, peel the film from the copper clad laminate 2 and straighten the film between the fitting rod 6 and the suction cups 51 into a horizontal state; the fitting rod 6 is arranged to move vertically, and is used to push the strip blocks 11 and cooperate with the conveyor belt 1 to convey the copper clad laminate 2.

[0023] As Figure 1 and Figure 5 shown in the figure, the waste discharging mechanism 7 includes a rotating shaft 71 vertically arranged on one side of the conveyor belt 1. The rotating shaft 71 is arranged to rotate around its own axis. The upper end of the rotating shaft 71 is connected with a horizontally arranged cross plate 72. At the end of the cross plate 72, there is a clamping part 73, which is used to cooperate with the rotation of the rotating shaft 71 to clamp the straightened film between the fitting rod 6 and the suction cups 51 and discharge the waste.

[0024] The working principle of the film peeling device will be described below according to the above structure: Feeding stage: As Figure 1As shown in the figure, the copper clad laminate 2 is placed between two horizontal strip-shaped blocks 11 by manual or automated feeding equipment. At the same time, the side stop bars 12 are respectively abutted against both sides of the copper clad laminate 2. At this time, the copper clad laminate 2 is horizontally arranged, and its length direction is consistent with the conveying direction of the conveyor belt 1. The matching rod 6 rises in the vertical direction and moves in the opposite direction to the conveying direction of the conveyor belt 1 to cross over a strip-shaped block 11. Then the matching rod 6 descends in the vertical direction and moves in the conveying direction of the conveyor belt 1 to abut against the crossed strip-shaped block 11 and push the strip-shaped block 11 in the conveying direction of the conveyor belt 1, thereby causing the conveyor belt 1 to convey in its conveying direction. When the matching rod 6 pushes the strip-shaped block 11 to move to the front end of the copper clad laminate 2 abutted behind the strip-shaped block 11, that is, one end of the copper clad laminate 2 facing the conveying direction of the conveyor belt 1, when it is located below the second matching plate 5, the matching rod 6 stops moving, that is, the conveyor belt 1 stops moving. At this time, the feeding of one copper clad laminate 2 is completed.

[0025] Film peeling stage: As Figure 2 , Figure 3 , Figure 4 , Figure 6 shown, after the feeding stage is completed, both the first matching plate 4 and the second matching plate 5 are located above the copper clad laminate 2, and the second matching plate 5 is located above the front end of the copper clad laminate 2. At this time, the first matching plate 4 and the second matching plate 5 move downward. The first matching plate 4 abuts against the copper clad laminate 2, and the suction cup 51 below the second matching plate 5 sucks the film at the front end edge of the copper clad laminate 2. The second matching plate 5 moves upward, and the first matching plate 4 presses down the copper clad laminate 2 to prevent the suction cup 51 from lifting the copper clad laminate 2 together. The film is separated from the front end of the copper clad laminate 2 due to the adsorption and lifting of the suction cup 51. The second matching plate 5 rises to lift the film to a predetermined height, and the first matching plate 4 moves upward to leave a running space for the matching rod 6. At this time, the film peeling operation at the front end of the copper clad laminate 2 is completed.

[0026] Film stripping stage: As Figure 6 and Figure 7 shown, the matching rod 6 moves in the opposite direction to the conveying direction of the conveyor belt 1 and enters between the film lifted by the suction cup 51 and the copper clad laminate 2. As the matching rod 6 continues to move, and since one end of the film is adsorbed by the suction cup 51, the film will be pulled by the matching rod 6, so that the film is continuously stripped from the copper clad laminate 2.

[0027] Waste discharging stage: As Figure 5 and Figure 8As shown, after the mating rod 6 enters between the film lifted by the suction cup 51 and the copper clad laminate 2, since the front end of the film is adsorbed and the rear end is still attached to the copper clad laminate 2, as the mating rod 6 continues to move, the film between the mating rod 6 and the suction cup 51 will be straightened by the mating rod 6 into a horizontal state. At this time, the rotating shaft 71 rotates, causing the clamping portion 73 at the end of the cross plate 72 to move to the film between the mating rod 6 and the suction cup 51 and clamp the film; when the film of the mating rod 6 is completely peeled off from the copper clad laminate 2, the rotating shaft 71 rotates in the reverse direction, driving the clamping portion 73 to clamp the film and move it to the outside of the conveyor belt 1. The clamping portion 73 releases the clamping state, and the film is collected by the corresponding collecting device, thereby realizing waste discharge.

[0028] When the mating rod 6 moves in the opposite direction of the conveying direction of the conveyor belt 1 to peel the film, it will approach the next strip 11. When the peeling of the mating rod 6 is completed, the mating rod 6 moves upward to cross the next strip 11, then moves downward and moves along the conveying direction of the conveyor belt 1, thereby pushing the next strip 11, that is, returning to the above feeding stage; at the same time, with the push of the mating rod 6, the conveyor belt 1 runs, and the copper clad laminate 2 that has completed the film is moved in the conveying direction of the conveyor belt 1. This process repeats, and the copper clad laminate 2 conveyed to the end of the conveyor belt 1 can be discharged manually or by a discharging device.

[0029] In summary, through the settings of the first mating plate 4, the second mating plate 5 and the suction cup 51, the film at the front edge of the copper clad laminate 2 can be adsorbed and lifted, and in cooperation with the first mating plate 4 pressing down the copper clad laminate 2, the film can be quickly separated from the copper clad laminate 2. At the same time, the first mating plate 4 can effectively prevent the film from warping, causing incomplete film peeling. This makes the film peeling method have a better film peeling effect compared with manual film peeling, effectively improving the production efficiency of printed circuit boards, and the film peeling method does not contact the circuit on the surface of the copper clad laminate 2 to ensure the product quality of the printed circuit board.

[0030] The mating rod 6 moves in the opposite direction of the conveying direction of the conveyor belt 1 and enters between the film lifted by the suction cup 51 and the copper clad laminate 2, which can not only continuously peel the film, but also straighten the film between the mating rod 6 and the suction cup 51 into a horizontal state, that is, during the film peeling process, the film presents a definite posture, which is convenient for the clamping of the clamping portion 73 in the waste discharging mechanism 7. Otherwise, the shape of the film is irregular, and it is not convenient to set corresponding structures to transfer and discharge the film; at the same time, the mating rod 6 after the film peeling is completed can also move to the rear of the next strip 11 and push it to the lower part of the second mating plate 5. Under the push of the mating rod 6, the conveyor belt 1 runs, and the copper clad laminate 2 that has completed the film peeling continues to be conveyed along the conveyor belt 1 for discharging. This process repeats, so that the reciprocating movement of the mating rod 6 can directly be used as the power source for the operation of the conveyor belt 1, and under the movement of the mating rod 6, the feeding and discharging of the copper clad laminate 2 have better continuity.

[0031] Correspondingly, there is a damping force between the transmission belt 1 and the transmission wheel 3, which can absorb the inertial kinetic energy of the copper clad laminate 2. Moreover, the moving speed of the fitting rod 6 is relatively slow, so that when the fitting rod 6 pushes the strip-shaped block 11 to move until the fitting rod 6 stops, the strip-shaped block 11 will not separate from the fitting rod 6 due to inertia. The transmission wheel 3 is arranged to rotate unidirectionally, which can prevent the transmission belt 1 from running in the reverse direction when the fitting rod 6 peels off the film. Specifically, a ratchet and pawl structure can be used to achieve the unidirectional rotation of the transmission wheel 3.

[0032] Embodiment 2 As a further embodiment of the above Embodiment 1, as Figures 1 to 4 shown, a lifting plate 8 is horizontally arranged above the transmission belt 1. Connecting plates 84 are vertically arranged on both sides of the lifting plate 8. A supporting plate 85 is arranged at the upper end of the connecting plate 84. A first linear mechanism 86 is arranged at the upper end of the supporting plate 85, and its movable end is connected to the supporting plate 85 for driving the lifting plate 8 to move in the vertical direction. The first linear mechanism 86 can adopt forms such as a linear cylinder or a hydraulic cylinder. As Figure 1 、 Figure 3 、 Figure 7 shown, the first fitting plate 4 and the second fitting plate 5 are vertically and slidably penetrated through the lifting plate 8. A guide rod 41 is vertically and slidably penetrated through the bottom of the first fitting plate 4. A pressing plate 42 located below the lifting plate 8 is connected to the lower end of the guide rod 41. A first spring 43 is sleeved on the guide rod 41, and the first spring 43 is connected between the bottom of the first fitting plate 4 and the pressing plate 42; A plurality of hollow tubes 52 are vertically and slidably penetrated through the top surface of the second fitting plate 5. The hollow tubes 52 are arranged in an array along the length direction of the second fitting plate 5. A first limit block 53 is arranged at the upper end of the hollow tube 52, and the first limit block 53 is located above the second fitting plate 5. The lower end of the hollow tube 52 is located below the second fitting plate 5 and is connected to a suction cup 51. A second limit block 54 is arranged at the connection between the suction cup 51 and the lower end of the hollow tube 52; First racks 81 are arranged on the opposite surfaces of the first fitting plate 4 and the second fitting plate 5. The two first racks 81 are vertically arranged with their tooth surfaces facing each other. A first motor 82 is arranged on the lifting plate 8, and its driving end is coaxially connected with a first gear 83. The first gear 83 is used to mesh with the first rack 81; The vertical distance between the bottom surface of the pressing plate 42 and the bottom of the suction cup 51 matches the distance between the bottom surface of the second fitting plate 5 and the second limit block 54. As Figure 4 shown, positioning blocks 55 are arranged on both sides of the second fitting plate 5 above the lifting plate 8. When the first gear 83 rotates and meshes with the first rack 81 until the positioning block 55 abuts against the lifting plate 8 and the first limit block 53 abuts against the upper end of the second fitting plate 5, the vertical distance between the bottom surface of the pressing plate 42 and the bottom of the suction cup 51 is equal to the distance between the bottom surface of the second fitting plate 5 and the second limit block 54.

[0033] During application, as Figure 4As shown in the figure, the first motor 82 drives the first gear 83. The first gear 83 meshes with the first rack 81, causing the positioning block 55 to abut against the top surface of the lifting plate 8. Under the action of gravity, the first limiting block 53 at the upper end of the hollow tube 52 abuts against the top surface of the second mating plate 5. Correspondingly, the weight of the first limiting block 53 can be increased to avoid jamming of the hollow tube 52. At this time, the vertical distance between the bottom surface of the pressing plate 42 and the bottom of the suction cup 51 is equal to the distance between the bottom surface of the second mating plate 5 and the second limiting block 54; when uncovering the film, the first mating plate 4 and the second mating plate 5 maintain the above posture. The first linear mechanism 86 drives the lifting plate 8 to move downward. The suction cup 51 first contacts the film, and the lifting plate 8 continues to move downward until the second mating plate 5 separates from the first limiting block 53 and abuts against and presses down the second limiting block 54. At this time, the pressing plate 42 abuts against the copper clad laminate 2. Due to the downward pressure of the second mating plate 5 on the first limiting block 53, the suction cup 51 can stably adsorb the film. After adsorption, the first gear 83 rotates, causing the first mating plate 4 to continue to press downward, the first spring 43 to contract, and the second mating plate 5 to abut against the first limiting block 53 and move upward, thereby driving the suction cup 51 to move upward, thus completing the film uncovering operation; correspondingly, the first limiting blocks 53 on each hollow tube 52 can be connected into one body to prevent the hollow tubes 52 from not moving downward synchronously when the second mating plate 5 moves upward, resulting in the suction cup 51 being unable to effectively adsorb the film.

[0034] Both the first mating plate 4 and the second mating plate 5 are arranged on the lifting plate 8 and are driven by a motor cooperating with a gear-rack mechanism, which has a high degree of integration. Moreover, by using one driving mechanism to simultaneously control the downward pressing of the pressing plate 42 against the copper clad laminate 2 and the lifting and film uncovering of the suction cup 51, the manufacturing cost is relatively low.

[0035] Specifically, as Figure 4 shown, an air pipe 56 is connected to the upper end of each hollow tube 52, and the end of the air pipe 56 is connected to an air source pump.

[0036] Embodiment 3 As a further implementation manner of the above Embodiment 1 and 2, as Figure 6 、 Figure 9 、 Figure 10As shown in the figure, the conveyor belt 1 and the driving wheel 3 are mounted on a substrate 9. On both sides of the conveyor belt 1, the substrate 9 is provided with slide bars 91 arranged along the conveying direction of the conveyor belt 1. The slide bars 91 are slidably fitted with sliders 92. The two sliders 92 move synchronously and in the same direction along the slide bars 91. On both sliders 92, mounting plates 93 are vertically provided. On the top of the mounting plate 93, a gantry 94 is provided, and its top is horizontally arranged. The top surface of the strip-shaped block 11 is arranged as an inclined surface slanting upward in the conveying direction of the conveyor belt 1. The matching rod 6 is a round rod and both ends are connected with horizontally arranged first support plates 95. The two first support plates 95 are respectively located within the corresponding gantries 94. Vertically provided on the first support plate 95 is a top rod 96. The upper end of the top rod 96 slidably passes through the top of the gantry 94 and is connected with a horizontally arranged second support plate 97. A second spring 98 is sleeved on the second support plate 97. The second spring 98 is connected between the second support plate 97 and the top of the gantry 94.

[0037] During application, since the top surface of the strip-shaped block 11 is arranged as an inclined surface slanting upward in the conveying direction of the conveyor belt 1, and the matching rod 6 is a round rod, when the matching rod 6 moves in the opposite direction of the conveying direction of the conveyor belt 1 until it abuts against the strip-shaped block 11, the matching rod 6 will move upward along the inclined surface of the strip-shaped block 11, the top rod 96 will move upward, and the second spring 98 will be stretched. Until the matching rod 6 moves out of the inclined surface of the strip-shaped block 11, the second spring 98 will contract, causing the matching rod 6 to move to the rear of the strip-shaped block 11. Then the matching rod 6 moves in the conveying direction of the conveyor belt 1, thereby pushing the strip-shaped block 11, realizing the feeding and discharging of the copper clad laminate 2. Through the inclined surface setting of the strip-shaped block 11 and the structural setting of the matching rod 6, and in cooperation with the second spring 98, during the movement of the matching rod 6, it automatically rises and falls to cross over and push the strip-shaped block 11, with a high degree of automation, a simple structure, and a low manufacturing cost.

[0038] Specifically, as Figure 6 and Figure 9 shown in the figure, the end of the slider 92 is connected with a second rack 921 parallel to the slide bar 91. On both sides of the conveyor belt 1, the substrate 9 is provided with rack frames 99. The second rack 921 is fitted within the corresponding rack frame 99. Inside the conveyor belt 1, a transmission rod 61 parallel to the matching rod 6 is mounted. The transmission rod 61 is rotatably arranged around its own axis. The transmission rod 61 is driven by a second motor 62 provided on the substrate 9. Two second gears 63 are coaxially provided on the transmission rod 61, respectively used for meshing with the corresponding second rack 921. Through the second rack 921 and the second gears 63, the synchronous and same-direction movement of the slider 92 can be effectively realized. At the same time, with the gear-rack structure, the transmission stability is relatively high, making the operation of the matching rod 6 more stable to ensure the continuity of film stripping.

[0039] Specifically, as Figure 5 、 Figure 8As shown in the figure, a third motor 74 is fixedly provided at the bottom of the substrate 9. The driving end of the third motor 74 vertically penetrates through the substrate 9 and is coaxially connected to the rotating shaft 71. The clamping portion 73 includes a clamping plate 75 horizontally arranged below the end of the cross plate 72. A pull rod 76 is vertically provided on the clamping plate 75. The pull rod 76 slidably penetrates through the cross plate 72 and is connected to a horizontally arranged third support plate 77. A second linear mechanism 78 is provided between the third support plate 77 and the cross plate 72. The second linear mechanism 78 is fixedly arranged on the cross plate 72, and its movable end is connected to the bottom of the third support plate 77. The second linear mechanism 78 can adopt a linear cylinder. When the film between the matching rod 6 and the suction cup 51 is in a horizontally taut state, the third motor 74 drives the rotating shaft 71 to rotate, so that the cross plate 72 and the clamping plate 75 are respectively located above and below the film. The second linear mechanism 78 extends, causing the clamping plate 75 to move towards the cross plate 72, thereby clamping the film. The third motor 74 drives the rotating shaft 71 to rotate in the reverse direction, and the film is removed from the conveyor belt 1 for waste discharge.

[0040] Specifically, as Figure 10 shown, mounting rods 64 parallel to the matching rod 6 are provided on the mounting plate 93 below the matching rod 6. One ends of the two mounting rods 64 are arranged oppositely, and both are coaxially rotatably fitted with pressing wheels 65 for rolling along the surface of the copper clad laminate 2, which can effectively prevent the copper clad laminate 2 from warping upwards when the matching rod 6 continuously peels the film, affecting the continuity of film peeling.

[0041] Preferably, a top plate can be fixedly erected on the substrate 9, and the first linear mechanism 86 is installed at the bottom of the top plate, and its movable end is vertically downward.

[0042] The above are only the preferred embodiments of the present application and are not used to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
