Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically to a cutting device for processing conductive tape. Background Technology

[0002] With the rapid development of the electronics industry, conductive tape, as an important material in the fields of electronic component packaging and circuit connection, is experiencing increasing market demand. In the field of conductive tape processing, cutting equipment is one of the key pieces of equipment on the production line, and its performance directly affects the production efficiency, product quality and cost of conductive tape.

[0003] A search revealed a utility model patent with Chinese patent publication number CN217256533U, which discloses a cutting device for the production and processing of conductive adhesive tape. The device includes a cutting box with a door hinged to its outer side and a cutting cover connected to the inner wall of the cutting box. A storage tray is nested on one side of the cutting box, and a handle is welded and fixed to the outer side of the storage tray. Rectangular grooves are provided on the left and right sides of the storage tray, and an auxiliary roller is bolted to the bottom of the storage tray.

[0004] The device described above uses a cutting blade to cut the tape. As the cutting blade is used, the adhesive will adhere to the outer wall of the blade, which will affect its sharpness. Furthermore, the tape will wear down after prolonged use, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for processing conductive tape, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing conductive tape, comprising a mounting frame, a cutting assembly mounted on the top of the mounting frame, four support plates fixedly connected to the outer wall of the top of the mounting frame, and a horizontally arranged guide roller rotatably connected to two of the support plates, the two guide rollers being located on both sides of the cutting assembly, the cutting assembly comprising mounting rods fixedly mounted on the top of the inner walls of both ends of the mounting frame, a vertically arranged lead screw threadedly connected inside the mounting rod, a movable plate rotatably connected to one bottom end of the lead screw, and two limiting rods slidably inserted inside the mounting rod, the bottom ends of both limiting rods being fixedly connected to the movable plate.

[0007] When the sharpness of the cutting blade decreases in one position, other positions can be quickly adjusted for continued use, ensuring smooth cutting without the need to replace the blade, thus maintaining work efficiency. As the cutting blade is used over time, adhesive residue accumulates on the part of the cutting blade, causing a decrease in sharpness. By rotating the knob, the lead screw rotates and moves downward along the mounting rod. The moving plate is restricted from rotating by the limit rod, so the moving plate is driven downward by the lead screw, and the cutting blade moves synchronously with the moving plate. The other positions of the cutting blade will then cut the tape, ensuring that the tape can still be cut quickly without wasting time replacing the cutting blade.

[0008] As a further preferred embodiment of this technical solution, two vertically arranged limiting rods are slidably inserted inside the movable plate. A limiting frame is fixedly connected to one bottom end of the limiting rod. A horizontally arranged motor is fixedly installed on the bottom outer wall of the movable plate. A transmission rod is fixedly connected to the output end of the motor. A connecting rod is rotatably connected to one end of the transmission rod. The bottom end of the connecting rod is hinged to the top of the limiting frame.

[0009] As a further preferred embodiment of this technical solution, the limiting frame has a horizontally arranged T-shaped groove inside, and several cutting blades are slidably inserted into the T-shaped groove through a slider. The limiting frame has several equally spaced insertion holes inside, and the same limiting pin is slidably inserted into the several insertion holes, and the limiting pin passes through the sliders of several cutting blades.

[0010] As a further preferred embodiment of this technical solution, two support components are installed on the top of the mounting frame, and the support components are respectively located on both sides of the top of the mounting frame.

[0011] As a further preferred embodiment of this technical solution, the support assembly includes a mounting groove formed at one end of the top outer wall of the mounting frame, a support seat placed inside the mounting groove, another support seat fixedly connected to the top outer wall of the mounting frame, a horizontally arranged lead screw 2 rotatably connected inside the mounting groove, the movable support seat forming a transmission engagement with the lead screw 2, two horizontally arranged limiting rods 3 fixedly connected inside the mounting groove, the support seat slidably sleeved on the outside of the two limiting rods 3, a motor 3 fixedly mounted on one end of the outer wall of the mounting frame, the output end of the motor 3 being coaxially fixed with one end of the lead screw 2, a snap-fit ​​shaft rotatably connected inside each of the two support seats, and a common take-up roller installed between the two snap-fit ​​shafts.

[0012] By controlling the motor to drive the lead screw to rotate, the support seat sleeved outside the limit rod will be driven by the lead screw to move outward, and the locking shaft will also disengage from the locking hole of the take-up roller, so that the take-up roller can be quickly removed and replaced, making the operation convenient enough.

[0013] As a further preferred embodiment of this technical solution, a motor is fixedly installed on the outer wall of one end of one of the support bases, and the output end of the motor is coaxially fixed with one of the snap-fit ​​shafts.

[0014] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread groove of the lead screw is less than the equivalent friction angle.

[0015] This utility model provides a cutting device for processing conductive tape, which has the following advantages:

[0016] (1) By setting up a cutting component, this utility model can quickly adjust other positions to continue use when the sharpness of the cutting knife decreases in one position, so that the cutting work can be carried out smoothly without replacing the knife, which is conducive to ensuring work efficiency. As the usage time increases, the part of the cutting knife that is put into use will be covered with adhesive, resulting in a decrease in sharpness. By driving the screw to rotate through the knob, the screw rotates and moves downward along the mounting rod. The moving plate is restricted by the limiting rod and cannot rotate. Therefore, the moving plate will be driven downward by the screw, and the cutting knife will also move synchronously with the moving plate. The other positions of the cutting knife will cut the tape, ensuring that the tape can still be cut quickly without wasting time to replace the cutting knife.

[0017] (2) By setting up a support component, the screw two is rotated by controlling the motor three drive. The support seat sleeved outside the limit rod three will be driven by the screw two to move outward. The snap-fit ​​shaft will also disengage from the snap-fit ​​hole of the take-up roller. The take-up roller can be quickly removed and replaced. The operation is convenient enough. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a cutting device for processing conductive tape includes a mounting frame 1. A cutting component 5 is mounted on the top of the mounting frame 1. Four support plates 2 are fixedly connected to the outer wall of the top of the mounting frame 1. A guide roller 3 is rotatably connected to the same horizontally arranged guide roller 3 relative to two support plates 2. The two guide rollers 3 are respectively located on both sides of the cutting component 5. The cutting component 5 includes mounting rods 501 fixedly mounted on the top of the inner walls of both ends of the mounting frame 1. A vertically arranged lead screw 503 is threaded inside the mounting rod 501. A movable plate 504 is rotatably connected to one bottom end of the lead screw 503. Two limiting rods 502 are slidably inserted inside the mounting rod 501. The bottom ends of the two limiting rods 502 are fixedly connected to the movable plate 504.

[0025] As usage time increases, the part of the cutting blade 507 that is in use becomes covered with adhesive, reducing its sharpness. By rotating the knob, the lead screw 503 rotates and moves downward along the mounting rod 501. The moving plate 504 is restricted from rotating by the limiting rod 502, so the moving plate 504 is driven downward by the lead screw 503. Consequently, the cutting blade 507 also moves synchronously with the moving plate 504. The other parts of the cutting blade 507 will cut the tape, ensuring that the tape can still be cut quickly without the need to spend time replacing the cutting blade 507.

[0026] Two vertically arranged limiting rods 505 are slidably inserted inside the movable plate 504. One end of the limiting rod 505 is fixedly connected to a limiting frame 506. A horizontally arranged motor 510 is fixedly installed on the bottom outer wall of the movable plate 504. A transmission rod 511 is fixedly connected to the output end of the motor 510. One end of the transmission rod 511 is rotatably connected to a connecting rod 512. One end of the connecting rod 512 is hinged to the top of the limiting frame 506. When the motor 510 at the bottom of the movable plate 504 is started, the motor 510 drives the transmission rod 511 to revolve around the axis of the motor 510. Since the limiting frame 506 is restricted by the limiting rods 505 and can only move up and down, the transmission rod 511 can drive the limiting frame 506 to move up and down reciprocally through the connecting rod 512. Consequently, the cutting blade 507 will also move up and down quickly, which helps to improve the cutting effect.

[0027] The limiting frame 506 has a horizontally arranged T-shaped groove inside, and several cutting blades 507 are slidably inserted into the T-shaped groove via sliders. The limiting frame 506 has several equally spaced insertion holes 508 inside, and the same limiting pin 509 is slidably inserted into the several insertion holes 508. The limiting pin 509 passes through the sliders of several cutting blades 507. A magnet is provided at the end of the limiting pin 509, and a magnet 2 that matches the magnet 1 is provided inside the limiting frame 506.

[0028] If the required size of the tape to be cut changes, first pull the limiting pin 509 out of the insertion hole 508, and the cutting blade 507 will no longer be restricted. Then push the cutting blade 507 to slide along the T-slot inside the limiting frame 506. Stop when the distance between multiple cutting blades 507 reaches a suitable distance, and ensure that the through hole of the cutting blade 507 corresponds to the insertion hole 508. Finally, insert the limiting pin 509 back into the insertion hole 508, and the position of multiple cutting blades 507 will be restricted again.

[0029] like Figure 1 and Figure 2 As shown, two support components 6 are installed on the top of the mounting bracket 1, and the support components 6 are located on both sides of the top of the mounting bracket 1.

[0030] The support assembly 6 includes a mounting groove 601 opened at one end of the top outer wall of the mounting frame 1. A support seat 604 is placed inside the mounting groove 601. Another support seat 604 is fixedly connected to the top outer wall of the mounting frame 1. A horizontally arranged lead screw 602 is rotatably connected inside the mounting groove 601. The movable support seat 604 and the lead screw 602 form a transmission engagement. Two horizontally arranged limit rods 603 are fixedly connected inside the mounting groove 601. The support seat 604 is slidably sleeved on the outside of the two limit rods 603. A motor 605 is fixedly installed on one end of the outer wall of the mounting frame 1. The output end of the motor 605 is coaxially fixed with one end of the lead screw 602. A snap-fit ​​shaft 606 is rotatably connected inside each of the two support seats 604. The same take-up roller is installed between the two snap-fit ​​shafts 606. The positions of the snap-fit ​​shafts 606 that are close to each other are set as rectangular blocks. The take-up roller is provided with a rectangular groove that matches the rectangular block.

[0031] After the tape on the take-up roller is wound up, the control motor 605 drives the lead screw 602 to rotate. The support seat 604, which is sleeved outside the limit rod 603, will be driven by the lead screw 602 to move outward. The locking shaft 606 will also disengage from the locking hole of the take-up roller, so the take-up roller can be quickly removed and replaced. The operation is convenient enough.

[0032] like Figure 1 and Figure 2 As shown, a motor 4 is fixedly installed on the outer wall of one end of one of the support bases 604. The output end of the motor 4 is coaxially fixed with one of the snap-fit ​​shafts 606. By controlling the motor 4, the winding speed of the winding roller can be adjusted to adapt to films of different thicknesses.

[0033] like Figure 1 and Figure 2 As shown, the thread helix angle of the external thread groove of the lead screw 503 is less than the equivalent friction angle, which gives it self-locking properties and ensures that the position of the movable plate 504 connected to it will not change with use.

[0034] This utility model provides a cutting device for processing conductive tape, the specific working principle of which is as follows:

[0035] When the device is working, the conductive tape on the surface of the unwinding roller is wrapped around the two guide rollers 3 and fixed to the take-up roller, so that multiple cutting blades 507 penetrate the conductive tape and move down a certain distance. The external motor 4 of the support base 604 is started, driving the clamping shaft 606 connected to it to rotate. The clamping shaft 606 then drives the take-up roller to wind up the tape, and the tape is cut into multiple small strips by the cutting blades 507. At the same time, the second motor 510 at the bottom of the moving plate 504 is started. The second motor 510 drives the transmission rod 511 to revolve around the rotating shaft of the second motor 510. The limiting frame 506 is restricted to moving only up and down by the limiting rod 505. The transmission rod 511, through the connecting rod 512, drives the limiting frame 506 to move up and down reciprocally, thereby causing the cutting blade 507 to move up and down rapidly, which is beneficial to improving the cutting effect. As the usage time increases, the part of the cutting blade 507 that has been used becomes covered with adhesive, resulting in a decrease in sharpness. By rotating the knob, the lead screw 503 rotates, and the lead screw 503 moves downward along the mounting rod 501. The moving plate 504 is restricted from rotating by the limiting rod 502, so the movement... The plate 504 is driven downward by the lead screw 503, and the cutting blade 507 moves synchronously with the moving plate 504. Other positions of the cutting blade 507 will cut the tape, ensuring the tape can still be cut quickly without the need to replace it. If the required cutting size of the tape changes, first pull the limiting pin 509 out of the insertion hole 508, and the cutting blade 507 will no longer be restricted. Then push the cutting blade 507 to slide along the T-slot inside the limiting frame 506. When multiple cutting blades 507 are... Stop at a suitable distance, ensuring that the through hole of the cutting blade 507 corresponds to the insertion hole 508. Finally, insert the limiting pin 509 back into the insertion hole 508, and the positions of the multiple cutting blades 507 are restricted again. After the tape of the take-up roller is wound up, drive the lead screw 602 to rotate by controlling the motor 3 605. The support seat 604 sleeved outside the limiting rod 3 603 will be driven to move outward by the lead screw 602. The locking shaft 606 will also disengage from the locking hole of the take-up roller, and the take-up roller can be quickly removed and replaced. The operation is convenient enough.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
