Description

Technical Field

[0001] This utility model relates to the technical field of adhesive paper tearing devices, and in particular to a gripper-type automatic adhesive paper tearing mechanism. Background Technology

[0002] One method for mounting and securing PCB or FPC circuit boards to a fixture is through high-temperature adhesive tape bonding. This involves using PI adhesive tape (high-temperature resistant polyimide tape) to bond the PCB or FPC circuit board to the fixture. During this process, a portion of the PI tape adheres to the PCB or FPC circuit board, while another portion adheres to the surface of the fixture.

[0003] After the PCB or FPC circuit board is processed, it needs to be removed from the tooling fixture. During this process, the PI adhesive tape needs to be peeled off in multiple locations. The traditional manual method of peeling off the adhesive tape is obviously time-consuming, labor-intensive, and inefficient.

[0004] It should be noted that Chinese invention patent application number 202510285680.4, entitled "A Paper-Tearing Device and Carding Production Line," discloses a paper-tearing device. Specifically, the paper-tearing device discloses the following technical solution: the device includes a conveying mechanism, a paper-tearing mechanism, a translation component, and a waste paper recycling device; the paper-tearing mechanism is located above the conveying mechanism and includes a fixed base, a lifting drive component, a mounting block, a pressure roller, a scraper, a clamping component, and a pushing drive component. The lifting drive component is vertically mounted on the fixed base. The mounting block is fixedly mounted on the bottom end of the telescopic rod of the lifting drive component. The pressure roller and scraper are both located on the bottom end of the mounting block and are kept flush. The pushing drive component is fixedly mounted on the mounting block. The clamping component consists of a rotating part, a clamping part, and a push rod part. The rotating part is rotatably connected to the bottom end of the mounting block, and the push rod part is hinged to the telescopic rod of the pushing drive component. The clamping component, under the action of the driving component, makes the clamping part abut against the scraper block; the waste adhesive paper recycling device includes a plate frame, a driving mechanism, a collecting cylinder, a tape roll, a bonding platform, and a pressure adjustment mechanism. The plate frame is rotatably equipped with a collecting roller, a discharging roller, and several guide rollers. Mounting cakes are fixedly installed on both the collecting roller and the discharging roller. The collecting cylinder is sleeved around the mounting cakes fixed on the collecting roller, and the tape roll is sleeved around the mounting cakes fixed on the discharging roller. The tape in the tape roll is wound around the periphery of each guide roller, passes through the pressure adjustment mechanism, and is wound around the collecting cylinder. The bonding platform is fixedly installed between the two guide rollers. The bonding platform is located below the tape and supports the tape. Waste adhesive paper is pasted onto the tape above the bonding platform.

[0005] It should be noted that, in the above-mentioned adhesive paper tearing device, during its operation, the adhesive paper is first torn off by the adhesive paper tearing structure. When the adhesive paper tearing mechanism is working, when it is necessary to tear the adhesive paper on the conveyor mechanism, the telescopic rod of the lifting drive extends, so that the bottom end of the pressure roller and the bottom end of the scraper block simultaneously abut against the paper. As the paper continues to be conveyed on the conveyor belt, the scraper block scrapes off the adhesive paper on the paper. Then, the telescopic rod of the swing cylinder extends, so that the clamping member rotates along the mounting block, causing the clamping part of the clamping member to move towards the scraper block until the clamping part and the scraper block clamp the scraped adhesive paper. As the conveyor mechanism continues to convey the paper, the adhesive paper on the paper is torn off. After the adhesive paper tearing mechanism tears off the adhesive paper on the paper, the translation module drives the adhesive paper tearing mechanism to move, placing the torn waste adhesive paper at the waste adhesive paper recycling device, which then recycles the torn waste adhesive paper.

[0006] It should be noted that the above-mentioned adhesive paper tearing device has the following defects, specifically: Defect 1: The adhesive paper tearing mechanism and the waste adhesive paper recycling device are two separate parts, resulting in poor structural compactness. After the adhesive paper tearing mechanism tears off the adhesive paper, it needs to be moved and the torn adhesive paper needs to be transferred to the waste adhesive paper recycling device for recycling. This action method will affect the efficiency of the adhesive paper tearing operation, that is, there is a problem of low adhesive paper tearing efficiency. Defect 2: The adhesive paper tearing mechanism of this adhesive paper tearing device separates the adhesive paper from the cardboard by scraping. This scraping method is obviously not suitable for PCB circuit boards or FPC circuit boards. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in conjunction with specific embodiments.

[0030] Example 1, as Figures 1 to 3 As shown, a gripper-type automatic adhesive tape tearing mechanism is used to tear PI adhesive tape 8 from a tooling fixture 9 and a circuit board 10, where the circuit board 10 is a PCB circuit board or an FPC circuit board. The gripper-type automatic adhesive tape tearing mechanism includes an adhesive tape peeling component and a waste adhesive tape recycling component. The waste adhesive tape recycling component includes a recycling drive motor 11, a recycling driven wheel 13 for placing the tape roll 12, a recycling drive wheel 14 driven by the recycling drive motor 11, and several tape guide wheels 15 for guiding the movement of the tape 121.

[0031] Among them, such as Figures 1 to 3 As shown, the gripper-type automatic adhesive paper tearing mechanism also includes a mounting bracket 2, a lifting drive component 3 mounted on the mounting bracket 2, and a vertically arranged lifting movable plate 4. The lifting drive component 3 is drivenly connected to the lifting movable plate 4. The recycling drive motor 11 is screwed onto the lifting movable plate 4, and the recycling drive wheel 14, the recycling driven wheel 13, and all the tape guide wheels 15 are rotatably mounted on the lifting movable plate 4.

[0032] Furthermore, such as Figures 1 to 6 As shown, the adhesive tape peeling assembly includes a gripper lifting cylinder 51 mounted on the lifting movable plate 4 and moving vertically. The driving end of the gripper lifting cylinder 51 is equipped with a gripper mounting block 52, and the lower end of the gripper mounting block 52 is equipped with a fixed gripper 53. The fixed gripper 53 is pivotally connected to a movable gripper 55 via a fixed pivot 54. The gripper mounting block 52 is equipped with a gripper opening and closing cylinder 56 corresponding to the movable gripper 55. The gripper opening and closing cylinder 56 is driven to connect with the movable gripper 55, and the gripper opening and closing cylinder 56 drives the movable gripper 55 to reciprocate between the closed position and the open position.

[0033] Furthermore, such as Figure 1 , Figure 2 as well as Figure 7 As shown, an auxiliary lifting plate 61 is installed on the front end of the fixed gripper 53 and the movable gripper 55. An auxiliary pressure block 62 is installed at the lower end of the auxiliary lifting plate 61. The auxiliary pressure block 62 is provided with two circuit board pressure heads 621 arranged at intervals on the left and right and protruding downwards respectively. An auxiliary holding cylinder 63 is installed on the upper end of the vertical mounting plate on the auxiliary lifting plate 61. The auxiliary holding cylinder 63 is drivenly connected to the auxiliary lifting plate 61.

[0034] In addition, such as Figure 3 and Figure 7As shown, among the plurality of tape guide rollers 15, there is a bottom guide roller 151 located at the lowest position, and an auxiliary pressure block 62 is located on the lower end side of the bottom guide roller 151. The upper surface of the auxiliary pressure block 62 is provided with a pressure groove 622 that is vertically aligned with the bottom guide roller 151. The plurality of tape guide rollers 15 cooperate to guide the tape 121 to pass under the bottom guide roller 151 with the adhesive side facing down.

[0035] It should be noted that, as Figure 8 As shown, the tooling fixture 9 has a clearance hole 91 at the PI adhesive tape 8 pasting position for the movable gripper 55 to extend into.

[0036] The following is a detailed description of the gripper-type automatic adhesive paper tearing mechanism in Embodiment 1, with reference to its specific working process. The working process includes the following steps: Step a: Install the tape roll 12 onto the recycling driven wheel 13, and peel off the tape 121 from the tape roll 12 and pass the tape 121 through several tape guide wheels 15 in sequence before sticking it onto the recycling drive wheel 14, so as to ensure that the tape 121 passes under the bottom guide wheel 151 and the adhesive side of the tape 121 located under the bottom guide wheel 151 faces down; Step b: After the tape 121 is wound, the tool 9 carrying the circuit board 10 moves to the tape tearing position. Step c: The lifting drive component 3 drives the lifting movable plate 4 to descend, and the lifting drive plate drives the adhesive peeling component and the waste adhesive recycling component to move down synchronously. Step d: After the lifting drive 3 drives the lifting movable plate 4 to move down to the position, the auxiliary holding cylinder 63 is activated and the auxiliary holding drive cylinder assists the lifting plate 61 to move down. The moving auxiliary lifting plate 61 drives the auxiliary pressing block 62 to move down, so that the two circuit board pressing heads 621 of the auxiliary pressing block 62 press down on the circuit board 10 on the tooling 9 respectively. The left circuit board pressing head 621 presses the circuit board 10 on the left side of the PI adhesive paper 8, and the right circuit board pressing head 621 presses the circuit board 10 on the right side of the PI adhesive paper 8. Step e: After the auxiliary pressure block 62 moves down and presses the circuit board 10, the gripper lifting cylinder 51 is activated and the gripper lifting cylinder drives the gripper mounting block 52, the fixed gripper 53, the gripper opening and closing cylinder 56 and the movable gripper 55 to move down synchronously, so that the fixed gripper 53 moves down to the gripping position and the movable gripper 55 falls into the clearance hole 91 of the tooling fixture 9. Step f: After the gripper mounting block 52 drives the gripper opening and closing cylinder 56 and the movable gripper 55 to move down to the position, the gripper opening and closing cylinder 56 is activated and drives the movable gripper 55 to close. At this time, the gripping end of the movable gripper 55 rotates upward about the fixed pivot 54 as the rotation center, so that the fixed gripper 53 cooperates with the movable gripper 55 and clamps the part of the PI adhesive paper 8 that is pasted on the tooling fixture 9. Step g: After the portion of the PI adhesive tape 8 adhered to the tooling fixture 9 is clamped by the fixed gripper 53 and the movable gripper 55, the lifting drive 3 drives the lifting movable plate 4 to move upward, and the lifting movable plate 4 drives the adhesive tape peeling component and the waste adhesive tape recycling component to move upward simultaneously. During this process, the fixed gripper 53 and the movable gripper 55 pull the PI adhesive tape 8 upward and cause the PI adhesive tape 8 to peel off from the surface of the tooling fixture 9 and the surface of the circuit board 10. When the PI adhesive tape 8 is peeled off, the circuit board pressure head 621 of the auxiliary pressure block 62 keeps pressing the circuit board 10 to prevent the circuit board 10 from being lifted when the adhesive tape is torn off. Step h: After the PI adhesive paper 8 is completely peeled off from the surface of the tooling fixture 9 and the circuit board 10, the auxiliary pressing cylinder 63 is activated and drives the auxiliary lifting plate 61 to move upward. The upward-moving auxiliary lifting plate 61 drives the auxiliary pressing block 62 to move upward and retract from the circuit board 10, so that the PI adhesive paper 8 held by the fixed clamping claw 53 and the movable clamping claw 55 is pressed into the tape 121 at the bottom guide wheel 151 position in the adhesive groove 622 of the auxiliary pressing block 62. Step i: After the auxiliary pressure block 62 makes the PI adhesive paper 8 stick to the tape 121 at the bottom guide wheel 151, the gripper opening and closing cylinder 56 drives the movable gripper 55 to adjust to the open position and makes the movable gripper 55 retract from the PI adhesive paper 8. The auxiliary pressing cylinder 63 drives the auxiliary lifting plate 61 to move down and makes the auxiliary pressure block 62 move down and detach from the PI adhesive paper 8, so that the PI adhesive paper 8 stays on the tape 121. Step j: The recycling drive motor 11 drives the recycling drive wheel 14 to rotate. The rotating recycling drive wheel 14 winds up the tape 121. The tape 121 carries the peeled PI tape 8 and winds it up to realize the waste tape recycling operation.

[0037] In summary, through the above structural design, the gripper-type automatic adhesive tape tearing mechanism of this embodiment can automatically and efficiently perform adhesive tape tearing operations. Compared with the prior art, the gripper-type automatic adhesive tape tearing mechanism of this embodiment has the advantages of novel structural design and high adhesive tape tearing efficiency, and can be effectively applied to adhesive tape tearing operations on PCB circuit boards or FPC circuit boards.

[0038] Example 2, as Figures 4 to 6As shown, the difference between this embodiment 2 and embodiment 1 is that: the gripper mounting block 52 is vertically slidably mounted with the opening and closing drive block 57 via the guide rail slider pair, and the drive end of the gripper opening and closing cylinder 56 is connected to the opening and closing drive block 57.

[0039] The opening and closing drive block 57 has a drive groove 571 corresponding to the movable gripper 55. The upper end of the movable gripper 55 is equipped with a drive shaft 58 on the upper side of the fixed pivot 54. The drive shaft 58 extends into the drive groove 571 of the opening and closing drive block 57.

[0040] When the gripper opening and closing cylinder 56 drives the movable gripper 55 to close to the fixed gripper 53, the gripper opening and closing cylinder 56 drives the opening and closing drive block 57 to move downward. The downward moving opening and closing drive block 57 drives the drive shaft 58 at the rear end of the movable gripper 55 to swing downward through its drive groove 571, thereby causing the gripping end of the movable gripper 55 to swing upward and close with the fixed gripper 53.

[0041] Example 3, as Figure 1 , Figure 2 as well as Figure 7 As shown, the difference between this embodiment three and embodiment one is that: the vertical mounting plate is screwed with an auxiliary mounting plate 64, the auxiliary pressing cylinder 63 is screwed onto the auxiliary mounting plate 64, and the auxiliary lifting plate 61 is slidably mounted on the auxiliary mounting plate 64 through the guide rail slider pair.

[0042] An auxiliary drive block 65 is installed between the drive end of the auxiliary holding cylinder 63 and the auxiliary lifting plate 61, and the drive end of the auxiliary holding cylinder 63 is connected to the auxiliary drive block 65; a spring assembly is installed between the auxiliary drive block 65 and the auxiliary lifting plate 61.

[0043] For the spring assembly in this embodiment 3, it enables the circuit board pressure head 621 of the auxiliary pressure block 62 to elastically press the circuit board 10; when the lifting drive 3 drives the lifting movable plate 4 to move upward and causes the PI adhesive paper 8 to peel off, the spring assembly enables the circuit board pressure head 621 to keep pressing the circuit board 10 to prevent the circuit board 10 from being pulled up when tearing off the adhesive paper.

[0044] Example 4, as Figure 7 As shown, the difference between this embodiment four and embodiment three is that the spring assembly includes a vertically arranged limiting bolt 661, and the auxiliary drive block 65 has a vertically penetrating bolt mounting hole corresponding to the limiting bolt 661. The threaded part of the limiting bolt 661 passes through the bolt mounting hole from top to bottom and is connected to the upper end of the auxiliary lifting plate 61. The large end of the limiting bolt 661 is located on the upper side of the auxiliary drive block 65.

[0045] Among them, a compression spring 662 is fitted around the limiting bolt 661. The upper end of the compression spring 662 elastically abuts against the auxiliary drive block 65, and the lower end of the compression spring 662 elastically abuts against the auxiliary lifting plate 61.

[0046] Example 5, such as Figure 1 and Figure 2 As shown, the difference between this fifth embodiment and the first embodiment is that the lifting drive component 3 includes a lifting drive cylinder 31 that is screwed onto the upper end of the vertical mounting plate and has a lifting action. The driving end of the lifting drive cylinder 31 is connected to the lifting movable plate 4, and the guide rail slider pair of the lifting movable plate 4 is slidably mounted on the vertical mounting plate.

[0047] Example 6, as Figures 1 to 3 As shown, the difference between this embodiment six and embodiment one is that: the mounting bracket 2 includes a horizontally arranged lifting plate 21, the lifting plate 21 is screwed with a linear guide rail 22, a movable slide block 23 is installed between the vertical mounting plate and the lifting plate 21, and the movable slide block 23 is screwed with a linear slider 24 corresponding to the linear guide rail 22, and the linear guide rail 22 and the linear slider 24 cooperate with each other.

[0048] The lifting drive component 3 is installed on the movable slide 23. A position fixing piece 25 is installed between the lifting plate 21 and the movable slide 23. The lower end of the position fixing piece 25 is fastened to the movable slide 23, and the upper end of the position fixing piece 25 is fastened to the lifting plate 21 by locking screws.

[0049] It should be explained that the lifting plate 21 has a T-shaped groove on the edge facing the position fixing plate 25, a nut can be inserted into the T-shaped groove, and a bolt that is screwed to the nut is installed at the upper end of the position fixing plate 25.

[0050] When using the gripper-type automatic adhesive tape tearing mechanism in this embodiment six, the operator can adaptably adjust the adhesive tape tearing operation position.

[0051] Example 7, as Figures 1 to 3 As shown, the difference between this embodiment seven and embodiment one is that: an elastic tension component 7 is installed on the side of the vertical mounting plate to recover the driven wheel 13. The elastic tension component 7 includes a swing member 71 rotatably mounted on the vertical mounting plate. The swing member 71 is rotatably mounted with a pressure wheel 72 that contacts the tape roll 12 at a position off-center from the rotation center.

[0052] Among them, a tension spring 73 is installed between the swing member 71 and the vertical mounting plate to cause the pressure wheel 72 to swing toward the tape roll 12. The two ends of the tension spring 73 are respectively connected to the vertical mounting plate and the swing member 71 on the corresponding side.

[0053] It should be noted that the swing component 71 is equipped with an angle sensor 74 for monitoring the rotation angle of the pressure wheel 72.

[0054] Furthermore, the swing component 71 is equipped with a release handle 75, and the release handle 75 and the swing component 71 are an integral structure.

[0055] It should be explained that, due to the elastic force of the tension spring 73, the pressure wheel 72 keeps pressing the tape roll 12 on the driven wheel 13, thereby ensuring that the tape 121 released from the tape roll 12 maintains a certain tension, thus ensuring that the tape 121 can stably and reliably stick to the peeled PI adhesive paper 8.

[0056] For the angle sensor 74 in this embodiment, it is used to monitor the rotation angle of the pressure roller 72. During operation, the angle sensor 74 can feed back the rotation angle of the pressure roller 72 to the controller. When the rotation angle of the pressure roller 72 reaches the set value, the controller controls the retraction drive motor 11 to stop, so as to realize the fixed length release of the tape 121.

[0057] Furthermore, when the recycling driven wheel 13 needs to replace the tape roll 12, the handle 75 is released and the clamping wheel 72 is moved away from the recycling driven wheel 13 so that the tape roll 12 can be smoothly placed onto the recycling driven wheel 13.

[0058] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
