Detailed implementation manners

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0035] It should be noted that when a component is referred to as "fixed" or "set" or "connected" to another component, it can be directly or indirectly located on that other component. The orientations or positions indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientations or positions shown in the drawings, and are only for convenience of description and should not be construed as limiting the technical solution of the present invention. Terms such as "first", "second", etc. are only for convenience of description purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "plural" is two or more, unless otherwise specifically defined. The meaning of "several" is one or more, unless otherwise specifically defined.

[0036] As Figures 1 to 4 shown, in an embodiment of the present utility model, an automatic adhesive tape peeling device includes a peeling mechanism 1. The peeling mechanism 1 includes a tape running component 101 around which a base tape 125 is wound. The tape running component 101 is used to drive the base tape 125 to run. A bonding layer for adhering to the adhesive tape 501 is provided on the working surface of the base tape 125. In this embodiment, the base tape 125 is a tape. The running of the base tape 125 is used to peel the adhesive tape 501. It further includes a frame 2, on which a conveying mechanism 3 for conveying the circuit board 5 and a transfer mechanism 4 for adjusting the relative positions of the peeling mechanism 1 and the circuit board 5 are provided.

[0037] When the device operates, first, the circuit board 5 to be processed is smoothly conveyed to a specified position through the conveying mechanism 3 and the transfer mechanism 4. Then, the tape running component 101 in the peeling mechanism 1 starts to work, driving the base tape 125 to run. So that the bonding layer on the working surface of the base tape 125 is opposite to the adhesive tape 501 on the circuit board 5. The transfer mechanism 4 adjusts the relative positions between the peeling mechanism 1 and the circuit board 5, and the adhesive tape 501 will be adhered by the bonding layer on the base tape 125. As the base tape 125 continues to run, the adhesive tape 501 is gradually peeled off from the circuit board 5. Then, the transfer mechanism 4 moves the peeling mechanism 1 to the next position where the adhesive tape 501 on the circuit board 5 needs to be peeled for peeling the adhesive tape 501 until all the adhesive tapes 501 that need to be peeled on the circuit board 5 are peeled off, and the conveying mechanism 3 conveys the circuit board 5 to the next circuit board 5 production station.

[0038] In this embodiment, by automatically peeling the adhesive tape 501, the production efficiency is greatly improved. Since the participation of manual labor is reduced, the risk of product contamination is lowered, and the overall quality and reliability of the product are improved. In addition, the device has a high degree of automation, is simple and convenient to operate, reduces the labor intensity of workers, and also reduces the production cost of the enterprise. Finally, by precisely controlling the relative positions between the peeling mechanism 1 and the circuit board 5, the accuracy and consistency of the peeling of the adhesive tape 501 are ensured, guaranteeing the performance and quality of the product.

[0039] like Figure 5 and Figure 6 As shown, in a preferred embodiment, the conveying mechanism 3 includes a fixed frame 301 connected to the frame 2 and a movable frame 302 slidably connected to the frame 2, and conveyor belts 303 parallel to each other are respectively arranged on the fixed frame 301 and the movable frame 302, and a width adjustment component is arranged between the fixed frame 301 and the movable frame 302, and the width adjustment component is used to adjust the distance between the two conveyor belts 303.

[0040] The width adjustment assembly includes a screw rod 304 and a slide rod 305. The screw rod 304 is threadedly connected to the movable frame 302, the screw rod 304 is rotatably connected to the fixed frame 301, and the slide rod 305 is movably connected to the movable frame 302. Rotating the screw rod 304 is used to increase or decrease the distance between the fixed frame 301 and the movable frame 302.

[0041] During production preparation, the staff operates the screw rod 304 to rotate it relative to the fixed frame 301. It can be manually operated by a wrench, or the motor is connected to the screw rod 304 by transmission, so as to drive the screw rod 304 to rotate by controlling the motor. Since the screw rod 304 is threadedly connected to the movable frame 302, and the movable frame 302 is slidably connected to its slide bar 305, as the screw rod 304 rotates, the movable frame 302 will move along the axial direction of the screw rod 304. By adjusting the rotation direction and number of rotations of the screw rod 304, the staff can effectively control the spacing between the fixed frame 301 and the movable frame 302, thereby realizing the precise adjustment of the spacing between the two conveyor belts 303. As the spacing increases or decreases, the conveyor belt 303 can adapt to circuit boards 5 of different widths, ensuring the stability and safety of the circuit boards 5 during the transportation process.

[0042] In this embodiment, by adjusting the spacing between the conveyor belts 303, the device can adapt to circuit boards 5 of different specifications, thereby improving the flexibility and adaptability of the production line, enabling the device to cope with diverse production needs, and reducing production costs and the frequency of equipment replacement. In addition, precise spacing adjustment ensures the stability and safety of the circuit boards 5 during transportation, and avoids damage to the circuit boards 5 caused by inappropriate spacing between the conveyor belts 303.

[0043] like Figure 6 As shown, in a preferred embodiment, a clamping assembly 306 is provided on the movable frame 302 and the fixed frame 301. The clamping assembly 306 includes a cylinder connected to the movable frame 302 or the fixed frame 301, a pressure plate is provided on the top of the cylinder piston rod, and a flexible clamping member is provided at the bottom of the pressure plate. The piston rod of the cylinder contracts to drive the flexible clamping member to lower its height through the pressure plate to press the circuit board 5 onto the conveyor belt 303 of the conveying mechanism 3.

[0044] During operation, the circuit board 5 is conveyed to the preset positions of the movable frame 302 and the fixed frame 301 through the conveyor belt 303. The piston rod of the cylinder contracts, driving the pressing plate at the top to gradually lower its height. As the pressing plate descends, the flexible pressing member at the bottom contacts the circuit board 5 and begins to apply a gradually increasing pressure to press the circuit board 5 against the conveyor belt 303. Then, the peeling mechanism 1 peels off the adhesive tape 501 on the circuit board 5. After the peeling of the adhesive tape 501 is completed, the piston rod of the cylinder extends to drive the flexible pressing member to lift its height through the pressing plate. At this time, the circuit board 5 is released and can be freely transported by the conveyor belt 303.

[0045] In this embodiment, through the cooperation of the piston rod of the cylinder and the pressing plate, the flexible pressing member can uniformly and stably apply pressure to the circuit board 5, so that the circuit board 5 is stably fixed at the preset position of the conveyor belt 303, ensuring the stability of peeling the adhesive tape 501. In addition, the flexible pressing member prevents damage to the circuit board 5 during the pressing process, thereby further improving the production safety and ensuring the production quality.

[0046] As Figure 5 shown, in a preferred example, the transfer mechanism 4 includes an X-axis moving component 401, a Y-axis moving component 402, a Z-axis moving component, and a Z-axis rotating component. The Z-axis moving component and the Z-axis rotating component are integrally arranged as a combination 403 of the Z-axis moving component and the Z-axis rotating component, and can also be separately arranged in actual applications. The Y-axis moving component 402 is arranged on the frame 2, the transportation mechanism is arranged at the movable end of the Y-axis moving component 402, a support frame is arranged on the frame 2, the X-axis moving component 401 is installed on the support frame, the Z-axis rotating component is arranged at the movable end of the X-axis moving component 401, the Z-axis moving component is arranged at the movable end of the Z-axis rotating component, and the peeling mechanism 1 is arranged at the movable end of the Z-axis moving component. The X-axis moving component 401, the Y-axis moving component 402, and the Z-axis moving component can be linear motion devices such as linear motors and pneumatic telescopic rods.

[0047] During operation, the various components of the transfer mechanism 4 work together to ensure that the adhesive tape 501 on the circuit board 5 can be accurately and efficiently peeled off. First, after the transport mechanism receives the circuit board 5, the Y-axis moving component 402 moves the transport mechanism together with the circuit board 5 to the working area of ​​the peeling mechanism 1 along the Y-axis direction. Next, under the control of the X-axis moving component 401, the peeling mechanism 1 moves along the X-axis direction to ensure that the position of the peeling mechanism 1 and the adhesive tape 501 on the circuit board 5 are aligned. Then, the Z-axis rotating component makes necessary rotation adjustments according to the position of the adhesive tape 501 on the circuit board 5, so that the peeling mechanism 1 can contact the adhesive tape 501 at the best angle. Finally, the Z-axis moving component starts to work, driving the peeling mechanism 1 to move along the Z-axis direction until the peeling mechanism 1 is in close contact with the adhesive tape 501 and the peeling process begins. After the adhesive tape 501 at the current position is peeled off, the transfer mechanism 4 moves to the next adhesive tape 501 position to peel off the adhesive tape 501 until all adhesive tapes 501 are peeled off. The circuit board 5 with the adhesive tape 501 peeled off is transported to the next station through the conveyor belt 303, and a new circuit board 5 with the adhesive tape 501 to be peeled off is received.

[0048] In this embodiment, the transfer mechanism 4 includes an X-axis moving component 401, a Y-axis moving component 402, and a combination 403 of a Z-axis moving component and a Z-axis rotating component, and has good flexibility and precision. The multi-axis motion configuration enables the peeling mechanism 1 to cover a wider working area and adapt to the adhesive tape 501 in different positions and orientations on the circuit board 5. At the same time, through precise motion control and adjustment, the peeling mechanism 1 can accurately locate the position of the adhesive tape 501 on the circuit board 5 and peel it at the best angle, thereby greatly improving the accuracy and efficiency of peeling.

[0049] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the tape transport assembly 101 includes a mounting frame 102, on which a unwinding reel 103 for releasing the base tape 125 and a reel 104 for recovering the base tape 125 are rotatably arranged, a driving motor 105 which is transmission-connected to the reel 104 is arranged on the mounting frame 102, and a plurality of guide wheels 106 are arranged on the tape transport path of the base tape 125 between the unwinding reel 103 and the reel 104.

[0050] During operation, the driving motor 105 rotates to drive the winding reel 104 to rotate, and the winding reel 104 winds the baseband 125. At the same time, the unwinding reel 103 also starts to rotate under the pulling force of the baseband 125, thereby releasing the baseband 125. The baseband 125 is on the tape running path between the unwinding reel 103 and the winding reel 104, and is guided by a number of guide wheels 106, ensuring the stability and smoothness of the baseband 125 during transmission. The guide wheels 106 are rotatably mounted on the mounting frame 102 to change the traveling direction of the baseband 125, ensuring that the baseband 125 can travel from the unwinding reel 103 to the winding reel 104 along the required path. As the winding reel 104 continues to rotate, the baseband 125 is gradually recovered, while the unwinding reel 103 continuously releases new baseband 125, forming a continuous and stable baseband 125 transmission process. When the baseband 125 on the unwinding reel 103 is released completely, a new roll of baseband 125 is replaced.

[0051] In this embodiment, through the transmission connection between the driving motor 105 and the winding reel 104, the automatic recovery and unwinding of the baseband 125 are realized, greatly improving the production efficiency. At the same time, the setting of the guide wheels 106 ensures the stability and smoothness of the baseband 125 during transmission, effectively avoiding problems such as deviation and distortion that may occur during the transmission of the baseband 125, and ensuring the accuracy and reliability of the baseband 125 transmission.

[0052] As Figures 1 to 4 shown, in a preferred example, the mounting frame 102 is made of aluminum, and there are many holes and cutouts, with a light overall weight, making it easier for the entire peeling mechanism 1 to move.

[0053] As Figure 1 and Figure 3 shown, in a preferred example, the guide wheel 106 includes a first guide wheel and a second guide wheel. The first guide wheel contacts the non-working surface of the baseband 125, and the second guide wheel is arranged on the working surface of the baseband 125. The wheel surface of the first guide wheel is a smooth surface, and baffles are arranged on both sides of the first guide wheel to prevent the baseband 125 from slipping off the first guide wheel. The wheel surface of the second guide wheel is provided with protrusions. Specifically, the second guide wheel is a gear, which can reduce the contact area between the wheel surface and the working surface of the baseband 125, thereby preventing the baseband 125 from adhering to the second guide wheel and affecting the tape running of the baseband 125, and ensuring the smooth tape running of the baseband 125.

[0054] As Figure 2As shown, in a preferred example, a tensioning assembly is provided on the tape running path between the unwinding reel 103 and the winding reel 104 of the baseband 125. The tensioning assembly includes a tensioning wheel 107. A slideway 108 is provided on the mounting bracket 102. The rotating shaft of the tensioning wheel 107 is slidably mounted in the slideway 108. A swinging member 109 is connected to the rotating shaft. The swinging member 109 is rotatably connected to the mounting bracket 102. A first positioning post 110 is provided at one end of the swinging member 109 away from the rotation. A second positioning post 111 is provided on the mounting bracket 102. A first spring 112 is connected between the first positioning post 110 and the second positioning post 111. The first spring 112 is used to adjust the position of the tensioning wheel 107 to tension the baseband 125.

[0055] During the operation of the tape running assembly 101, the baseband 125 is transmitted between the unwinding reel 103 and the winding reel 104. The rotating shaft of the tensioning wheel 107 slides in the slideway 108. Through the rotational connection between the swinging member 109 and the mounting bracket 102, flexible adjustment of the tensioning wheel 107 is achieved. When the tension of the baseband 125 is insufficient, the first spring 112 pulls the first positioning post 110 and the second positioning post 111 closer to each other, prompting the swinging member 109 to rotate upward, and then pushing the tensioning wheel 107 to slide along the slideway 108, increasing the length of the tape running path of the baseband 125 between the unwinding reel 103 and the winding reel 104, thereby increasing the tension of the baseband 125. Conversely, when the tension of the baseband 125 is too high, the tensioning wheel 107 slides reversely along the slideway 108 under the pulling force of the baseband 125, and the first spring 112 is stretched, reducing the tension of the baseband 125.

[0056] In this embodiment, through the adjustment of the first spring 112, dynamic control of the tension of the baseband 125 is achieved, preventing wear and faults caused by uneven tension of the baseband 125, and ensuring the stability and reliability of the baseband 125 during transmission. Secondly, the sliding installation of the tensioning wheel 107 and the rotational connection of the swinging member 109 make the adjustment process more flexible and stable. By replacing the first spring 112, the tension of the baseband 125 can be quickly adjusted according to different production requirements.

[0057] In actual application, in addition to adjusting the tension through a spring, a counterweight can also be set to dynamically adjust the tension of the baseband 125 through the gravity of the counterweight.

[0058] As Figure 2 shown, in a preferred example, a flexible contact member 113 is further provided on the swinging member 109. A limiting block 114 is provided on the mounting bracket 102. The flexible contact member 113 contacts the limiting block 114 to limit the swing of the swinging member 109. An induction sheet 115 is provided on the side of the swinging member 109 where the flexible contact member 113 is provided. An inductor 116 for sensing the position of the induction sheet 115 is provided on the limiting block 114.

[0059] During operation, the tension of the base tape 125 is adjusted at all times. The rotating shaft of the tension pulley 107 slides in the slideway 108, driving the swing member 109 to swing. Under the action of the pulling force of the base tape 125, when the swing member 109 swings to the first extreme position, that is, the rotating shaft of the tension pulley 107 moves to the lowermost end of the slideway 108. At this time, the flexible contact member 113 contacts the limit block 114 on the mounting bracket 102, restricting the further swing of the swing member 109. At the same time, the induction sheet 115 provided on the swing member 109 will move with the movement of the swing member 109. When the induction sheet 115 is at the first extreme position, it is sensed by the inductor 116 on the limit block 114. The sensing process provides a real-time feedback signal for the control system, enabling the control system to accurately know the position of the swing member 109 and the adjustment state of the tension pulley 107, thereby making corresponding adjustment instructions to remind the staff to check and confirm whether the base tape 125 is in a tightened state. Only the base tape 125 in a tightened state has good adhesion. Under the action of the pulling force of the first spring 112, when the swing member 109 swings to the second extreme position, that is, the rotating shaft of the tension pulley 107 moves to the uppermost end of the slideway 108, at this time the tape running path of the base tape 125 is the longest.

[0060] In this embodiment, by providing the flexible contact member 113 and the limit block 114, the contact between the flexible contact member 113 and the limit block 114 effectively restricts the swing amplitude of the swing member 109, thereby controlling the adjustment range of the tension pulley 107 and preventing the problem of unstable tension of the base tape 125 caused by excessive swing of the swing member 109. At the same time, when the flexible contact member 113 contacts the limit block 114, it plays a role of buffering and vibration reduction, preventing rigid contact from damaging components, and effectively ensuring the stability and safety of operation. Secondly, the cooperation of the induction sheet 115 and the inductor 116 provides real-time position feedback for the control system, enabling the control system to understand the adjustment state of the tension pulley 107 in real time and make accurate adjustment instructions accordingly, such as stopping the machine and giving an alarm, improving the response speed of the entire tape running assembly 101 and the intelligent level of the control system.

[0061] Both the flexible pressing member and the flexible contact member 113 include a connecting portion and a contact portion. The connecting portion is a bolt, and the contact portion is made of a flexible material, such as rubber or silica gel.

[0062] As Figure 4 shown, in a preferred example, a damping member for restricting rotation is provided between the unwind reel 103 and the mounting bracket 102. The damping member includes a second spring 117 sleeved on the rotating shaft of the unwind reel 103. A bearing is sleeved on the rotating shaft of the unwind reel 103. One end of the second spring 117 abuts against the bearing, and the other end of the second spring 117 abuts against the mounting bracket 102.

[0063] When the unwinding reel 103 starts to rotate, its rotating shaft will rotate accordingly. The bearing sleeved on the rotating shaft will also rotate with the rotation of the rotating shaft. Since one end of the second spring 117 abuts against the bearing and the other end abuts against the mounting bracket 102, the rotational resistance of the rotating shaft is increased, preventing the unwinding reel 103 from rotating due to inertia during rotation, thereby preventing excessive release of the baseband 125 and causing the baseband 125 to become slack, thus effectively controlling the rotation speed of the unwinding reel 103.

[0064] In this embodiment, by increasing the rotational resistance of the rotating shaft, the damping member can prevent the unwinding reel 103 from excessively releasing the baseband 125 due to inertia during rotation, thereby ensuring the stability and tension of the baseband 125. Secondly, it can reduce the slack and wrinkle phenomena of the baseband 125 during transmission, ensuring production stability and production efficiency.

[0065] As Figure 1 shown, in a preferred example, the unwinding reel 103 includes a first mounting base plate, and a first mounting pressing plate is detachably connected to one side of the first mounting base plate; the winding reel 104 includes a second mounting base plate, and a second mounting pressing plate is detachably connected to one side of the second mounting base plate. Specifically, bolts are provided on the mounting base plate, the mounting pressing plate is sleeved on the pressing plate, and hand-tightening nuts are provided on the bolts.

[0066] When replacing the new baseband 125 roll or removing the used baseband 125 roll, the operator loosens the hand-tightening nut to release the connection between the first mounting pressing plate and the second mounting pressing plate. Then, the operator separates the mounting pressing plate from the mounting base plate, and places a new baseband 125 roll on the unwinding reel 103 or removes the baseband 125 roll on the winding reel 104. After completing the replacement of the baseband 125 roll, the operator again sleeved the mounting pressing plate on the mounting base plate and tightens it by rotating the hand-tightening nut, thereby ensuring the stability of the baseband 125 roll during operation.

[0067] In this embodiment, the mounting base plate and the mounting pressing plate are connected by a detachable connection method, simplifying the operation process of replacing the baseband 125 roll, enabling the operator to quickly and easily complete the replacement work of the baseband 125 roll, thereby improving work efficiency. Secondly, since the mounting pressing plate is tightened on the mounting base plate by a hand-tightening nut, the stability of the baseband 125 roll during installation can be ensured, preventing possible shaking or falling off during operation. In addition, it also has good versatility, can adapt to different specifications and types of baseband 125 rolls, and improves the applicability and flexibility of the equipment.

[0068] As Figures 1 to 4As shown, in a preferred example, a peeling head 118 extending downward is provided on the mounting bracket 102. The peeling head 118 includes a mounting plate 119, and a roller 120 is rotatably provided at the bottom of the mounting plate 119. The base tape 125 bypasses the roller 120.

[0069] The mounting plate 119 includes a fixed mounting plate 121 connected to the mounting bracket 102. A movable mounting plate 122 is provided below the fixed mounting plate 121. A sliding guide post 123 is connected between the fixed mounting plate 121 and the movable mounting plate 122, and a third spring 124 is sleeved on the sliding guide post 123.

[0070] During operation, the base tape 125 passes through the roller 120 of the peeling head 118. When peeling the adhesive tape 501, the peeling head 118 moves downward, so that the working surface of the base tape 125 contacts the adhesive tape 501. The cross-sectional area of the peeling head 118 is small, and it can accurately move above the adhesive tape 501 without touching the components on the circuit board 5. At this time, the third spring 124 is compressed, and the movable mounting plate 122 slides along the sliding guide post 123, and the distance between the fixed mounting plate 121 and the movable mounting plate 122 decreases, thereby buffering the contact force between the peeling head 118 and the circuit board 5, preventing damage to the circuit board 5, and ensuring close contact and adhesion between the base tape 125 and the adhesive tape 501. Then the peeling head 118 moves upward, and the third spring 124 elastically resets, so that the distance between the movable mounting plate 122 and the fixed mounting plate 121 is restored. At the same time, the adhesive tape 501 is peeled off, and the tape feeding mechanism drives the base tape 125 to wind up a certain distance, so that a new section of the base tape 125 winds around the roller 120, preparing for peeling the next adhesive tape 501.

[0071] In this embodiment, through the combined use of the third spring 124 and the sliding guide post 123, the movable mounting plate 122 can slide when the peeling head 118 moves, buffering the contact force between the peeling head 118 and the circuit board 5 and preventing damage to the circuit board 5. At the same time, it also ensures close contact and firm adhesion between the base tape 125 and the adhesive tape 501 during the peeling process, ensuring the production quality and thus ensuring the product quality. In addition, the small cross-sectional area of the peeling head 118 enables it to accurately move above the adhesive tape 501, avoiding contact with the components on the circuit board 5 and ensuring the safety of the circuit board 5.

[0072] A circuit board production line according to an embodiment of the present utility model includes the above-mentioned automatic adhesive tape peeling device.

In addition, the device has a high degree of automation, is simple and convenient to operate, reduces the labor intensity of workers, and also reduces the production cost of the enterprise, making it suitable for assembly line production.
