Description

Technical Field

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

[0002] When producing printed circuit boards (PCBs), a layer of photoresist film is applied to the copper-clad laminate (CCL) to serve as a mask for subsequent pattern transfer. A hot press is typically used to evenly press the film onto the CCL surface, followed by exposure and development to complete the pattern transfer. After curing, the photoresist film retains a certain degree of flexibility and film-forming properties, and is not completely brittle. At this point, the film needs to be peeled off the CCL to reveal the complete circuitry. In mass production, operators typically lift the film from the edge of the copper plate, leveraging the continuity and toughness of the cured film to gradually remove the entire sheet of photoresist. However, manual film removal is time-consuming and labor-intensive, hindering PCB production efficiency. Summary of the Invention

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

[0006] The transmission belt has strip blocks arranged in an array along its outer side along its contour, which are used to abut the front and rear ends of the copper clad plate;

[0007] At least two transmission wheels are used to tension the transmission belt in the horizontal direction. When the transmission belt is in tension, the strip blocks are arranged along the axis of the transmission wheel;

[0008] A first matching plate is vertically arranged above the transmission belt and arranged toward the axis of the transmission wheel, and the first matching plate is arranged to move along the vertical direction;

[0009] The second matching plate is arranged parallel to the first matching plate and is movable in the vertical direction. The first matching plate and the second matching plate are arranged along the conveying direction of the conveyor belt. The bottom of the second matching plate is provided with a plurality of suction cups arranged along its length direction for sucking the film;

[0010] The matching rod is horizontally mounted above the transmission belt, with its axis parallel to the axis of the transmission wheel. The matching rod is movable along the conveying direction of the transmission belt and in the opposite direction thereof, and is used to enter between the film and the copper-clad laminate, peel the film off the copper-clad laminate, and straighten the film between the matching rod and the suction cup to a horizontal state. The matching rod is movable in the vertical direction, and is used to push the strip block and cooperate with the transmission belt to convey the copper-clad laminate.

[0011] The waste discharge mechanism includes a rotating rod vertically arranged on one side of the transmission belt, the rotating rod is arranged to rotate around its own axis, the upper end of the rotating rod is connected to a horizontally arranged horizontal plate, and the end of the horizontal plate is provided with a clamping part, which is used to cooperate with the rotation of the rotating shaft to clamp the film in a straight state between the cooperating rod and the suction cup and discharge the waste.

[0012] The beneficial effects of the present invention are:

[0013] 1. Through the arrangement of the first matching plate, the second matching plate and the suction cup, the film at the front edge of the copper clad laminate can be adsorbed and lifted, and the first matching plate can press down the copper clad laminate to quickly separate the film from the copper clad laminate. At the same time, the first matching plate can effectively prevent the film from warping, which would cause incomplete film stripping, and effectively improve the production efficiency of printed circuit boards.

DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1

[0028] The embodiment of the present application provides a copper clad laminate film peeling device, such as Figures 1 to 8 As shown, it includes: a transmission belt 1, a transmission wheel 3, a first matching plate 4, a second matching plate 5, a matching rod 6, a waste discharge mechanism 7, etc.

[0029] Among them, such as Figure 1 and Figure 2 As shown, in this embodiment, the transmission belt 1 is a synchronous belt, and the transmission pulleys 3 are synchronous pulleys. There are three transmission pulleys 3, which are arranged parallel to each other. The plane formed by the axes of the three transmission pulleys 3 is always horizontal. Each transmission pulley 3 rotates unidirectionally and in the same direction about its own axis. The two synchronous pulleys on either side horizontally tension the synchronous belt and engage with the synchronous belt for transmission. The middle synchronous pulley engages with the synchronous belt and provides support, so that the transmission belt 1 is tensioned and horizontal. Accordingly, an additional tensioning mechanism can be provided to ensure the horizontal tension and load-bearing capacity of the transmission belt 1. The use of a synchronous belt for the transmission belt 1 and synchronous pulleys for the transmission pulleys 3 ensures transmission efficiency between the transmission belt 1 and the transmission pulleys 3 and prevents slippage between the transmission belt 1 and the transmission pulleys 3.

[0030] like Figure 1 and Figure 2 As shown, strip blocks 11 are arranged in an array along the contour of the outer side of the transmission belt 1. When the transmission belt 1 is in a tensioned state, the strip blocks 11 are arranged along the axial direction of the transmission wheel 3. The distance between two adjacent strip blocks 11 on the horizontal part of the transmission belt 1 is equal to the length of the copper clad plate 2, which is used to abut the front and rear ends of the copper clad plate 2; side guard bars 12 are provided on both sides between two adjacent strip blocks 11, and the distance between the guard bars 12 on both sides is equal to the width of the copper clad plate 2, which is used to abut both sides of the copper clad plate 2; during the movement of the transmission belt 1, the strip blocks 11 and the side guard bars 12 can effectively limit the copper clad plate 2, which can effectively prevent the copper clad plate 2 from being offset, so as to facilitate subsequent film peeling and tearing operations.

[0031] like Figures 1 to 4 As shown, the first matching plate 4 is vertically arranged above the transmission belt 1 and is arranged toward the axis direction of the transmission wheel 3. The first matching plate 4 is movable in the vertical direction, and its lower end is used to press down the copper clad laminate 2; the second matching plate 5 is arranged parallel to the first matching plate 4 and is movable in the vertical direction. The first matching plate 4 and the second matching plate 5 are arranged along the conveying direction of the transmission belt 1. The bottom of the second matching plate 5 is provided with a plurality of suction cups 51 arranged along its length direction. The layout length of the suction cup 51 is consistent with the width of the copper clad laminate 2, which is used to suck the film.

[0032] like Figures 1 to 3 As shown, the cooperating rod 6 is horizontally mounted above the transmission belt 1, and the axis of the cooperating rod 6 is arranged parallel to the axis of the transmission wheel 3. The cooperating rod 6 is arranged to move along the conveying direction of the transmission belt 1 and the opposite direction, and is used to enter between the film and the copper clad laminate 2, peel the film off the copper clad laminate 2 and stretch the film between the cooperating rod 6 and the suction cup 51 to a horizontal state; the cooperating rod 6 is arranged to move along the vertical direction, and is used to push the strip block 11 and cooperate with the transmission belt 1 to convey the copper clad laminate 2.

[0033] like Figure 1 and Figure 5 As shown, the waste discharge mechanism 7 includes a rotating shaft 71 vertically arranged on one side of the transmission belt 1, and the rotating shaft 71 is arranged to rotate around its own axis. The upper end of the rotating shaft 71 is connected to a horizontally arranged cross plate 72, and the end of the cross plate 72 is provided with a clamping portion 73, which is used to cooperate with the rotation of the rotating shaft 71 to clamp the film in a straight state between the matching rod 6 and the suction cup 51 and discharge the waste.

[0034] The working principle of the film peeling device is described below based on the above structure:

[0035] Feeding stage: Figure 1As shown, manual or automatic loading equipment is used to place the copper clad board 2 between the two horizontal blocks 11, and the side guard bars 12 are respectively abutted on both sides of the copper clad board 2. At this time, the copper clad board 2 is arranged horizontally, and its length direction is consistent with the conveying direction of the transmission belt 1; the matching rod 6 rises in the vertical direction and moves in the opposite direction of the conveying direction of the transmission belt 1 to pass over a strip block 11, and the matching rod 6 then descends in the vertical direction and moves in the conveying direction of the transmission belt 1 to abut the passed strip block 11 and push the strip block 11 along the conveying direction of the transmission belt 1, thereby causing the transmission belt 1 to be transmitted in its conveying direction; when the matching rod 6 pushes the strip block 11 to move to the front end of the copper clad board 2 abutted behind the strip block 11, that is, the end of the copper clad board 2 facing the conveying direction of the transmission belt 1 and located below the second matching plate 5, the matching rod 6 stops moving, that is, the transmission belt 1 stops moving, and the feeding of one copper clad board 2 is completed at this time.

[0036] Unveiling stage: Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 As shown, after the feeding stage is completed, the first matching plate 4 and the second matching plate 5 are both located above the copper clad board 2, and the second matching plate 5 is located above the front end of the copper clad board 2. At this time, the first matching plate 4 and the second matching plate 5 move down, the first matching plate 4 is against the copper clad board 2, and the suction cup 51 under the second matching plate 5 sucks the film at the front edge of the copper clad board 2. The second matching plate 5 moves up, and the first matching plate 4 presses down the copper clad board 2 to prevent the suction cup 51 from lifting the copper clad board 2 together. The film is adsorbed and lifted by the suction cup 51 and separated from the front end of the copper clad board 2. The second matching plate 5 rises to lift the film to a predetermined height, and the first matching plate 4 moves up to leave space for the matching rod 6 to operate. At this time, the film peeling operation at the front end of the copper clad board 2 is completed.

[0037] Stripping stage: Figure 6 and Figure 7 As shown, the cooperating rod 6 moves in the opposite direction of the conveying direction of the transmission belt 1 and enters between the film lifted by the suction cup 51 and the copper clad laminate 2. As the cooperating rod 6 continues to move and one end of the film is adsorbed by the suction cup 51, the film will be pulled by the cooperating rod 6, thereby continuously peeling the film from the copper clad laminate 2.

[0038] Waste discharge stage: Figure 5 and Figure 8As shown, after the cooperating 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 cooperating rod 6 continues to move, the film between the cooperating rod 6 and the suction cup 51 will be stretched straight by the cooperating rod 6 to a horizontal state. At this time, the rotating shaft 71 rotates, so that the clamping part 73 at the end of the cross plate 72 moves to the film between the cooperating rod 6 and the suction cup 51, and clamps the film; when the film of the cooperating rod 6 is completely peeled off from the copper clad laminate 2, the rotating shaft 71 rotates in the opposite direction, driving the clamping part 73 to clamp the film and move it to the outside of the transmission belt 1. The clamping part 73 releases the clamping state, and the film is collected by the corresponding collection device, thereby realizing waste discharge.

[0039] When the cooperating rod 6 moves in the opposite direction of the conveying direction of the transmission belt 1 to peel off the film, it will approach the next strip block 11. When the cooperating rod 6 completes the peeling, the cooperating rod 6 moves up to pass over the next strip block 11, and then moves down and moves along the conveying direction of the transmission belt 1, thereby pushing the next strip block 11, that is, returning to the above-mentioned feeding stage; at the same time, as the cooperating rod 6 pushes, the transmission belt 1 runs, and the copper-clad laminate 2 that has completed the film moves in the conveying direction of the transmission belt 1, and the cycle is repeated. The copper-clad laminate 2 conveyed to the end of the transmission belt 1 can be discharged manually or by a discharging device.

[0040] To sum up, through the arrangement of the first cooperating plate 4, the second cooperating plate 5 and the suction cup 51, the film at the front edge of the copper clad board 2 can be adsorbed and lifted, and the first cooperating plate 4 presses down the copper clad board 2, so that the film can be quickly separated from the copper clad board 2. At the same time, the first cooperating plate 4 can effectively prevent the film from warping up, causing the problem of incomplete film stripping, so that the film stripping method has a better film stripping effect than manual film stripping, effectively improving the production efficiency of the printed circuit board, and the film stripping method will not contact the circuit on the surface of the copper clad board 2, so as to ensure the product quality of the printed circuit board.

[0041] The cooperating rod 6 moves in the opposite direction of the conveying direction of the transmission belt 1 and enters between the film lifted by the suction cup 51 and the copper clad plate 2, which can not only continuously peel off the film, but also straighten the film between the cooperating rod 6 and the suction cup 51 into a horizontal state, that is, in the process of stripping, the film is made to present a certain posture, so as to facilitate the clamping of the clamping part 73 in the waste discharge mechanism 7, otherwise the shape of the film is irregular, and it is inconvenient to set up a corresponding structure to transfer and discharge the film; at the same time, the cooperating rod 6 after the film stripping is completed can also move to the rear of the next strip block 11 and push it to move to the bottom of the second cooperating plate 5. Under the push of the cooperating rod 6, the transmission belt 1 runs, and the copper clad plate 2 after the film stripping is completed continues to be transported along the transmission belt 1 for discharge, and the cycle is repeated. In this way, the reciprocating movement of the cooperating rod 6 can be directly used as the power source for the operation of the transmission belt 1, and under the movement of the cooperating rod 6, the feeding and discharging of the copper clad plate 2 has good continuity.

[0042] Accordingly, a damping force exists between the transmission belt 1 and the transmission wheel 3, absorbing the inertial kinetic energy of the copper-clad laminate 2. Furthermore, the movement speed of the mating rod 6 is relatively slow, so that when the mating rod 6 pushes the strip block 11 to stop, the strip block 11 does not separate from the mating rod 6 due to inertia. The unidirectional rotation of the transmission wheel 3 prevents the transmission belt 1 from running in the opposite direction when the mating rod 6 is stripping the film. Specifically, a ratchet and pawl structure can be used to achieve the unidirectional rotation of the transmission wheel 3.

[0043] Example 2

[0044] As a further implementation of the above embodiment 1, Figures 1 to 4 As shown, a lifting plate 8 is horizontally provided above the transmission belt 1, and connecting plates 84 are vertically provided on both sides of the lifting plate 8. A support plate 85 is provided on the upper end of the connecting plate 84, and a first linear mechanism 86 is provided on the upper end of the support plate 85. Its movable end is connected to the support plate 85 and is used to drive the lifting plate 8 to move in the vertical direction. The first linear mechanism 86 can be in the form of a linear cylinder, a hydraulic cylinder, etc. Figure 1 、 Figure 3 、 Figure 7 As shown, the first matching plate 4 and the second matching plate 5 are vertically slidably penetrated by the lifting plate 8, the bottom of the first matching plate 4 is vertically and slidably penetrated by a guide rod 41, the lower end of the guide rod 41 is connected to a pressure plate 42 located below the lifting plate 8, and a first spring 43 is sleeved on the guide rod 41, and the first spring 43 is connected between the bottom of the first matching plate 4 and the pressure plate 42; the top surface of the second matching plate 5 is vertically and slidably penetrated by a plurality of hollow tubes 52, each hollow tube 52 is arranged in an array along the length direction of the second matching plate 5, and a first limit block 53 is provided at the upper end of the hollow tube 52, and the first limit block 53 is located on the second matching plate 5 The lower end of the hollow tube 52 is located below the second matching plate 5 and is connected to the suction cup 51. A second limit block 54 is provided at the connection between the suction cup 51 and the lower end of the hollow tube 52. First racks 81 are provided on the opposite surfaces of the first matching plate 4 and the second matching plate 5. The two first racks 81 are vertical and the tooth surfaces are arranged opposite to each other. A first motor 82 is provided on the lifting plate 8, and its driving end is coaxially connected to 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 pressure plate 42 and the bottom of the suction cup 51 matches the distance between the bottom surface of the second matching plate 5 and the second limit block 54. Figure 4 As shown, positioning blocks 55 are provided on both sides of the second mating plate 5 above the lifting plate 8. When the first gear 83 rotates and engages 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 mating plate 5, the vertical distance between the bottom surface of the pressure 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 limit block 54.

[0045] When applied, such as Figure 4As shown, the first motor 82 drives the first gear 83, and the first gear 83 meshes with the first rack 81, so that the positioning block 55 abuts against the top surface of the lifting plate 8. Under the action of gravity, the first limit block 53 at the upper end of the hollow tube 52 abuts against the top of the second matching plate 5. Accordingly, the weight of the first limit block 53 can be increased to avoid the hollow tube 52 from getting stuck. 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 matching plate 5 and the second limit block 54; when peeling off the film, the first matching plate 4 and the second matching 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 matching plate 5 is separated from the first limit block 53 and abuts against and presses down the second limit block 54. At this time, the pressure plate 42 abuts against the copper clad board 2. Due to the downward pressure of the second matching plate 5 on the first limit block 53, the suction cup 51 can stably adsorb the film. After adsorption, the first gear 83 rotates, so that the first matching plate 4 continues to press down, the first spring 43 contracts, and the second matching plate 5 abuts against the first limit block 53 and moves up, thereby driving the suction cup 51 to move up, thereby completing the film peeling operation; accordingly, the first limit blocks 53 on each hollow tube 52 can be connected as a whole to avoid the situation where the hollow tubes 52 do not move down synchronously when the second matching plate 5 moves up, causing the suction cup 51 to be unable to effectively adsorb the film.

[0046] The first mating plate 4 and the second mating plate 5 are both arranged on the lifting plate 8 and driven by a motor and a gear rack mechanism, which has a high degree of integration. A driving mechanism is used to simultaneously control the pressing plate 42 to press down the copper clad board 2 and the lifting and peeling of the film by the suction cup 51, which has a low manufacturing cost.

[0047] Specifically, such as Figure 4 As shown, the upper end of each hollow tube 52 is connected to an air pipe 56, and the end of the air pipe 56 is connected to an air source pump.

[0048] Example 3

[0049] As a further implementation of the above embodiments 1 and 2, Figure 6 、 Figure 9 、 Figure 10As shown, the transmission belt 1 and the transmission wheel 3 are mounted on a base plate 9. The base plates 9 on both sides of the transmission belt 1 are provided with slide bars 91 arranged along the conveying direction of the transmission belt 1. The slide bars 91 are slidably matched with slide blocks 92. The two slide blocks 92 move synchronously and in the same direction along the slide bars 91. A mounting plate 93 is vertically provided on the two slide blocks 92. A door frame 94 is provided on the top of the mounting plate 93. The top of the mounting plate 93 is provided with a door frame 94. The top is arranged horizontally. The top surface of the strip block 11 is arranged at an inclined surface facing obliquely upward in the conveying direction of the transmission belt 1. The matching rod 6 is a round rod and is connected to a horizontally arranged first support plate 95 at both ends. The two first support plates 95 are respectively located in the corresponding door frames 94. A top rod 96 is vertically provided on the first support plate 95. The upper end of the top rod 96 slides through the top of the door frame 94 and is connected to 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 door frame 94.

[0050] During application, since the top surface of the strip block 11 is inclined upward in the conveying direction of the transmission belt 1, and the mating rod 6 is a round rod, when the mating rod 6 moves in the opposite direction of the conveying direction of the transmission belt 1 to abut the strip block 11, the mating rod 6 will move up along the inclined surface of the strip block 11, the top rod 96 moves up, and the second spring 98 stretches until the mating rod 6 moves out of the inclined surface of the strip block 11. The second spring 98 contracts, causing the mating rod 6 to move to the rear of the strip block 11. Thereafter, the mating rod 6 moves along the conveying direction of the transmission belt 1, thereby pushing the strip block 11 and realizing the feeding and discharging of the copper clad laminate 2. Through the inclined surface setting of the strip block 11 and the structural setting of the mating rod 6, and in conjunction with the second spring 98, the mating rod 6 automatically rises and falls during the movement to pass over and push the strip block 11, which has a high degree of automation, a simple structure, and a low manufacturing cost.

[0051] Specifically, such as Figure 6 and Figure 9 As shown, the end of the slider 92 is connected to a second rack 921 parallel to the slide bar 91, and a rack frame 99 is provided on the base plate 9 on both sides of the transmission belt 1. The second rack 921 cooperates with the corresponding rack frame 99. A transmission rod 61 arranged parallel to the matching rod 6 is provided on the inner side of the transmission belt 1. The transmission rod 61 is rotated around its own axis. The transmission rod 61 is driven by a second motor 62 arranged on the base plate 9. Two second gears 63 are coaxially provided on the transmission rod 61, which are respectively used to engage with the corresponding second rack 921. Through the second rack 921 and the second gear 63, the slider 92 can be effectively moved synchronously and in the same direction. At the same time, the gear and rack structure has a higher transmission stability, which makes the matching rod 6 run more stably to ensure the continuity of film stripping.

[0052] Specifically, such as Figure 5 、 Figure 8When the second linear mechanism 78 is extended, the splint 75 moves toward the horizontal plate 72, thereby clamping the film, and the third motor 74 drives the rotating shaft 71 to rotate in the opposite direction, and the film is moved out of the transmission belt 1 for waste discharge.

[0053] Specifically, such as Figure 10 As shown, a mounting rod 64 parallel to the mating rod 6 is provided on the mounting plate 93 below the mating rod 6. One end of the two mounting rods 64 is arranged opposite to each other and both rotate coaxially with a pressure wheel 65 for rolling along the surface of the copper clad laminate 2. This can effectively prevent the copper clad laminate 2 from tilting upward when the mating rod 6 continuously strips the film, thereby affecting the continuity of the film stripping.

[0054] Preferably, a top plate can be fixedly mounted on the base plate 9, and the first linear mechanism 86 can be installed on the bottom of the top plate with its movable end facing vertically downward.

[0055] The above description is only a preferred embodiment of the present application and is not intended 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.
