Description

Technical Field

[0001] This invention relates to the field of integrated circuit board processing equipment technology, and in particular to a high-efficiency cutting device for flexible integrated circuit board substrates. Background Technology

[0002] For cutting integrated circuit board substrates, there are two main technologies: blade cutting and laser cutting. Blade cutting mainly uses a high-speed rotating grinding wheel for cutting, which is low-cost, highly efficient, and a relatively mature process due to its physical contact operation. However, current blade cutting equipment is often only suitable for rigid circuit board substrates and cannot be applied to flexible circuit board substrates. Moreover, traditional cutting equipment has a fixed structure, making it inconvenient to store and transport, and also inconvenient for substrate replacement. Summary of the Invention

[0003] The technical problem this invention aims to solve is that current blade cutting equipment can only be used on rigid circuit board substrates and cannot be applied to flexible circuit board substrates. Moreover, traditional cutting equipment has a fixed structure, making it inconvenient to store and transport, and also inconvenient to replace substrates.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a high-efficiency cutting device for flexible integrated circuit board substrate, including a T-shaped longitudinal frame, mounting back plates installed at both ends of the longitudinal frame, an upper guide tube and a lower guide tube installed inside the longitudinal frame, electrically controlled cutting components installed on both side walls of the longitudinal frame, electrically controlled lateral flipping guide frames hinged to both sides of the longitudinal frame, an electrically controlled lifting base installed at the bottom of the longitudinal frame, and a detachable substrate roll mounted on the mounting back plate.

[0005] The mounting back plate is fixedly installed on the lower end of the top crossbeam of the longitudinal frame. A rear motor is provided on the back of the mounting back plate, and a mounting screw is provided on the front of the mounting back plate. A locking nut is threaded onto the mounting screw.

[0006] A gap is provided between the upper and lower guide tubes, and the electronically controlled cutting assembly is located in the gap between the upper and lower guide tubes.

[0007] The electronically controlled cutting assembly includes a transverse guide frame fixedly mounted on both sides of the longitudinal frame via a lateral bracket, an internal control seat slidably mounted inside the transverse guide frame, a replaceable cutting blade mounted on one side of the internal control seat, and a control support rod mounted on the outside of the transverse guide frame.

[0008] The electrically controlled lateral tilting guide frame includes a main tilting frame hinged to both sides of the longitudinal frame, an electrically controlled conveyor belt installed inside the main tilting frame, and a bottom electrically controlled support rod for controlling the main tilting frame.

[0009] The electrically controlled lifting base includes an inverted T-shaped bottom frame, a bottom lifting support rod installed inside the bottom frame, and bottom casters installed on the lower surface of the bottom frame.

[0010] The detachable substrate roll has a side-mounted locking bracket on its side wall that cooperates with the mounting screw. The detachable substrate roll is connected to the mounting back plate by being fitted onto the mounting screw through the side-mounted locking bracket. An internal winding drum controlled by a rear-mounted motor is movably assembled inside the detachable substrate roll.

[0011] The lower guide tube includes a longitudinally fixed lower guide tube installed inside the longitudinal frame, a longitudinally movable lower guide tube hinged to the lower opening of the longitudinally fixed lower guide tube, a transmission gear set installed on the outside of the mounting frame at the lower end of the longitudinally fixed lower guide tube, and an external motor for controlling the transmission gear set.

[0012] The vertically positioned lower movable guide tube has an integrated arc-shaped guide cover on both sides of the upper opening.

[0013] Roller-type inner metering modules and side-mounted electric drive wheels are installed on the inner walls of both sides of the upper guide pipe and the longitudinally placed lower fixed guide pipe.

[0014] The beneficial effects of this invention are: (1) The high-efficiency cutting equipment for flexible integrated circuit board substrate of the present invention adopts a vertical structure design and is laid out by top feeding, middle cutting and bottom feeding. It uses the gravity of the flexible integrated circuit board substrate itself to maintain verticality, ensures flatness during the cutting process and improves cutting efficiency. (2) Electrically controlled lateral tilting guide frames are hinged on both sides of the longitudinal frame, and a detachable substrate roll is installed on the mounting back plate. It can be unfolded outward during use and stored during storage and transportation, thus improving space utilization. (3) An electrically controlled lifting base is provided at the bottom of the longitudinal frame, which can adjust the height of the equipment as needed to improve its applicability; (4) An upper guide pipe and a lower guide pipe are installed inside the longitudinal frame. The conveying length of the substrate can be accurately measured by the roller-type inner metering module and the side-mounted electric drive wheel on the inner wall of the upper and lower guide pipes, and the tension can be guaranteed, which is convenient for cutting and measurement. (5) The lower guide tube consists of a longitudinally fixed guide tube and a longitudinally movable guide tube. Its angle can be controlled by an external motor, thereby guiding the cut substrate to different positions of the electrically controlled lateral flipping guide frame, so that it can classify and guide substrates of different cutting specifications.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Figure 1 , Figure 2 and Figure 3 The high-efficiency cutting equipment for flexible integrated circuit board substrates shown includes a T-shaped longitudinal frame 1, with mounting back plates 2 installed at both ends of the longitudinal frame 1. An upper guide tube 3 and a lower guide tube 4 are installed inside the longitudinal frame 1. Electrically controlled cutting components 5 are provided on both side walls of the longitudinal frame 1. Electrically controlled lateral flipping guide frames 6 are hinged to both sides of the longitudinal frame 1. An electrically controlled lifting base 7 is provided at the bottom of the longitudinal frame 1. A detachable substrate roll 8 is mounted on the mounting back plate 2.

[0023] To facilitate installation, the mounting back plate 2 is fixedly installed at the lower end of the top crossbeam of the longitudinal frame 1. A rear motor 21 is provided on the back of the mounting back plate 2, and a mounting screw 22 is provided at the front of the mounting back plate 2. A locking nut is threaded onto the mounting screw 22.

[0024] To facilitate cutting, a gap is provided between the upper guide tube 3 and the lower guide tube 4, and the electronically controlled cutting assembly 5 is located in the gap between the upper guide tube 3 and the lower guide tube 4.

[0025] To facilitate electronic cutting, the electronic cutting assembly 5 includes a transverse guide frame 51 fixedly mounted on both sides of the longitudinal frame 1 by a lateral bracket, an internal control seat 52 slidably mounted inside the transverse guide frame 51, a replaceable cutting blade 53 mounted on one side of the internal control seat 52, and a control support rod 54 mounted on the outside of the transverse guide frame 51.

[0026] The control strut 54 controls the internal control seat 52 to slide and translate within the horizontal guide frame 51 through telescopic control, thereby driving the replaceable cutting blade 53 to perform transverse cutting on the flexible integrated circuit board substrate from both sides.

[0027] To facilitate lateral material guiding, the electrically controlled lateral tilting guide frame 6 includes a main tilting frame 61 hinged to both sides of the longitudinal frame 1, an electrically controlled conveyor belt 62 installed inside the main tilting frame 61, and a bottom electrically controlled support rod 63 for controlling the main tilting frame 61.

[0028] The bottom-mounted electrically controlled support rod 63 controls the tilting adjustment of the main tilting frame 61 by telescopic extension.

[0029] To facilitate lifting, the electrically controlled lifting base 7 includes a bottom frame 71 with an inverted T-shaped structure, a bottom lifting support rod 72 installed inside the bottom frame 71, and bottom casters 73 installed on the lower surface of the bottom frame 71.

[0030] The bottom frame 71 is inserted into the lower opening of the longitudinal frame 1 for sliding assembly.

[0031] To facilitate installation and control, a side-mounted locking bracket 81 is provided on the side wall of the detachable substrate roll 8 to cooperate with the mounting screw 22. The detachable substrate roll 8 is connected to the mounting back plate 2 by being fitted onto the mounting screw 22 through the side-mounted locking bracket 81. An internal winding drum 82 controlled by a rear motor 21 is movably assembled inside the detachable substrate roll 8.

[0032] To facilitate angle adjustment and guide the cut substrate in different directions, the lower guide tube 4 includes a longitudinally fixed lower guide tube 41 installed inside the longitudinal frame 1, a longitudinally movable lower guide tube 42 hinged to the lower opening of the longitudinally fixed lower guide tube 41, a transmission gear set 43 installed on the outside of the mounting frame at the lower end of the longitudinally fixed lower guide tube 41, and an external motor 44 for controlling the transmission gear set 43.

[0033] An integral gear structure is provided on the connecting end face of the vertically placed lower movable guide tube 42, which meshes with the transmission gear set 43. The external motor 44 drives the transmission gear set 43 to rotate the vertically placed lower movable guide tube 42, thereby adjusting the angle of the discharge port.

[0034] To ensure material guiding stability, the upper opening of the vertically placed lower movable material guide tube 42 has an integrated arc-shaped material guide cover 45 on both sides.

[0035] To facilitate internal material guiding and metering, roller-type inner metering modules 9 and side-mounted electric drive wheels 10 are installed on the inner walls of both sides of the upper guide pipe 3 and the longitudinally placed lower fixed guide pipe 41.

[0036] When the internal winding drum 82 inside the detachable substrate roll 8 is controlled by the rear motor 21 to guide the external substrate from the top into the upper guide tube 3, the roller-type inner metering module 9 and the side-mounted electric drive wheel 10 inside the upper guide tube 3 are used for measurement and material guiding. Then, the substrate is guided down from the upper guide tube 3 into the lower guide tube 4, where the roller-type inner metering module 9 and the side-mounted electric drive wheel 10 are used for measurement and material guiding.

[0037] There is a certain difference in rotation speed between the side-mounted electric drive wheel 10 inside the upper guide tube 3 and the vertically placed lower fixed guide tube 41, thereby ensuring the verticality of the flexible integrated circuit board substrate.

[0038] Equipment working process First, move the equipment to the designated work area using the bottom casters 73 of the electrically controlled lifting base 7. Then, according to the height of the operating table or the work requirements, start the bottom lifting support rod 72 to drive the bottom frame 71 to slide up and down along the lower opening of the longitudinal frame 1 to adjust the overall height of the equipment. After the adjustment is completed, lock the bottom lifting support rod 72 to ensure the stability of the equipment. Check the connection status of each component: confirm that the mounting back plate 2 is firmly fixed to the top beam of the longitudinal frame 1, the horizontal guide frame 51 of the electric control cutting assembly 5 is reliably connected to the two side walls of the longitudinal frame 1 through the side bracket, the replaceable cutting blade 53 is installed on one side of the internal control seat 52 without looseness, and the longitudinally placed lower movable guide tube 42 and the longitudinally placed lower fixed guide tube 41 are hinged flexibly.

[0039] Remove the locking nut on the mounting screw 22, put the side locking bracket 81 of the detachable substrate roll 8 into the mounting screw 22, adjust the position of the roll and then tighten the locking nut again to fix the detachable substrate roll 8 to the mounting back plate 2. Start the rear motor 21 and check whether its transmission connection with the internal winding drum 82 inside the detachable substrate roll 8 is smooth, to ensure that the internal winding drum 82 can rotate smoothly to release the substrate. The flexible substrate end on the internal winding drum 82 is manually pulled through the inside of the upper guide tube 3 and the cutting gap between the upper guide tube 3 and the lower guide tube 4 in sequence, and finally introduced into the interior of the vertically placed lower fixed guide tube 41, ensuring that the substrate is in full contact with the roller-type inner metering module 9 and the side-mounted electric drive wheel 10 in the two guide tubes without jamming.

[0040] The cutting parameters are preset through the electronic control system: according to the required substrate specifications, the length threshold of the roller-type inner metering module 9 (i.e. the substrate length of a single cut), the rotation speed of the side-mounted electric drive wheel 10 (set the speed difference between the upper and lower sections, usually the upper section speed is 5%-10% higher than the lower section), and the cutting speed of the electronically controlled cutting component 5 are set. Set classification and guiding parameters: Based on the cutting specifications and quantity, preset the flipping angle of the vertically placed lower movable guide tube 42, and start the bottom electric control support rod 63 to push the main flipping frame 61 to flip outward to the position corresponding to the material outlet of the vertically placed lower movable guide tube 42, ensuring that the electric control conveyor belt 62 is in a horizontal receiving state.

[0041] When the main switch of the equipment is turned on, the rear motor 21 drives the internal winding drum 82 to rotate at a constant speed, releasing the flexible substrate; the side-mounted electric drive wheel 10 in the upper guide tube 3 rotates, driving the substrate to be conveyed downwards, while the roller-type inner metering module 9 counts the rolling of the rollers, measures the substrate conveying length in real time, and feeds the data back to the control system. After the substrate enters the longitudinally fixed lower guide tube 41, the lower side-mounted electric drive wheel 10 rotates at a preset speed, forming a speed difference with the upper side-mounted electric drive wheel 10, so that the substrate is kept taut between the two guide tubes; the roller-type inner metering module 9 inside the longitudinally fixed lower guide tube 41 checks the conveying length again to ensure accurate measurement data and avoid length errors caused by the stretching of the flexible substrate.

[0042] When the substrate conveying length fed back by the roller-type inner metering module 9 reaches the preset threshold, the control system immediately sends a cutting signal; the control rod 54 of the electric cutting component 5 quickly extends and retracts, pushing the internal control seat 52 to slide laterally towards the center in the horizontal guide frame 51; the internal control seat 52 drives the replaceable cutting blade 53 to move synchronously, and performs lateral shearing on the flexible substrate taut between the two guide tubes from both sides. After the cutting is completed, the control strut 54 drives the internal control seat 52 and the replaceable cutting blade 53 to quickly reset, waiting for the next cutting signal. The whole cutting process is short and the cut is flat, avoiding tearing of the flexible substrate due to uneven cutting force.

[0043] The cut substrate fragments enter the longitudinally placed movable guide tube 42 under the action of gravity. The arc-shaped guide cover 45 at the upper end of the tube wraps around both sides of the substrate to prevent the substrate from deviating from the guide channel. According to the preset classification parameters, the control system starts the external motor 44, drives the transmission gear set 43 to rotate, and the transmission gear set 43 drives the vertically placed lower movable guide tube 42 to rotate around the hinge point to the corresponding angle, so that the discharge port is aligned with the electrically controlled lateral flipping guide frame 6 on one side. The substrate fragments fall onto the electrically controlled conveyor belt 62 inside the main flipping frame 61. The electrically controlled conveyor belt 62 rotates at a constant speed, transporting the substrate fragments to the designated collection container. If it is necessary to switch the cutting specifications, simply adjust the flipping angle of the vertically placed movable guide tube 42 through the control system to guide it to the electrically controlled lateral flipping guide frame 6 on the other side, so as to achieve classified collection.

[0044] Once all the substrate on the internal winding drum 82 has been cut, the control system issues a stop signal, and the rear motor 21, side-mounted electric drive wheel 10, electric control cutting assembly 5, electric control conveyor belt 62 and other components stop operating synchronously. Loosen the locking nut on the mounting screw 22, remove the detachable substrate roll 8, and replace it with a new substrate roll or store the empty roll. Start the bottom-mounted electric control support rod 63, retract it to drive the main flipping frame 61 to flip and fold towards the longitudinal frame 1, reducing the space occupied by the equipment; If the equipment needs to be moved, unlock the bottom lifting support 72, adjust the equipment height to the lowest level, and push the equipment to the storage area using the bottom casters 73 to complete the operation.

[0045] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
