Description

Technical Field

[0001] This utility model relates to the technical field of PCB board cutting devices, and in particular to a PCB board cutting equipment. Background Technology

[0002] In the PCB manufacturing process, there is a process of cutting the original PCB substrate. The core purpose of this process is to trim the substrate's shape and size, remove process edges and irregular allowances, so as to provide accurate boundary references for subsequent lamination, stacking or panelization.

[0003] To effectively improve single-batch production efficiency, existing technologies generally introduce a stacking process, which involves neatly stacking multiple original substrates of the same specifications and clamping them together at once, then simultaneously cutting the same side. However, when using this method, operators need to disassemble and re-align the substrates whenever they need to switch to an adjacent side after processing one side. This repeated disassembly and repositioning process not only consumes a lot of auxiliary time, but also makes it difficult to guarantee the consistency of the cutting dimensions of each board. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a PCB board cutting device to avoid repetitive positioning processes for each board and accelerate the overall production line cycle of the cutting process.

[0005] The technical implementation scheme of this utility model is as follows: a PCB board cutting device, comprising: a base; a control console fixedly connected to the side of the base; the device further comprising: a base slidably connected to the inside of the base along a horizontal longitudinal direction; a movable frame slidably connected to the base along a horizontal longitudinal direction, the movable frame being fixedly connected to the base; a first electric slide rail fixedly connected to the inside of the base, the control end of the first electric slide rail being fixedly connected to the base; a motor fixedly connected to the base; a tray rotatably connected to the movable frame; the rotating shaft of the tray being drively connected to the output shaft of the motor; a first hydraulic cylinder fixedly connected to the upper part of the movable frame; a pressure plate fixedly connected to the telescopic end of the first hydraulic cylinder, the axis of the pressure plate coinciding with the axis of the tray; an inner plate coaxially rotatably connected to the lower surface of the pressure plate via a connecting shaft; a mounting frame fixedly connected to the rear of the base; a first pad fixedly connected to the lower part of the mounting frame; a second hydraulic cylinder fixedly connected to the upper part of the mounting frame; a cutter slidably connected to the mounting frame along a vertical direction and fixedly connected to the telescopic end of the second hydraulic cylinder; the first electric slide rail, the motor, the first hydraulic cylinder, and the second hydraulic cylinder are all signal connected to the control console.

[0006] Optionally, the device further includes: a second electric slide rail fixedly connected to the side wall of the mounting frame, the second electric slide rail being signal-connected to the control console; a mounting seat slidably connected vertically to the mounting frame, the mounting seat being fixed to the control end of the second electric slide rail; a clamping plate fixedly connected to the lower surface of the mounting seat; and a second pad fixedly connected to the lower part of the mounting frame; the clamping surfaces of the clamping plate and the second pad are located on the front side of the cutting surface formed by the cutter and the first pad.

[0007] Optionally, the device further includes: a mounting rod fixedly connected to the front of the mounting frame; a camera fixedly connected to the mounting rod for capturing real-time images of the PCB board at the cutting station; a laser emitter fixedly connected to the mounting rod for projecting marking lines corresponding to the cutting lines onto the surface of the PCB board; both the camera and the laser emitter are connected to the control console for signal connection.

[0008] Optionally, the device further includes: ball bearings embedded in the outer periphery of the inner disc connecting shaft to reduce the frictional resistance when the inner disc rotates relative to the pressure plate.

[0009] Optionally, the device further includes a friction pad fixedly connected to the lower surface of the inner tray and the upper surface of the tray to increase the contact friction with the PCB board.

[0010] Optionally, the device further includes: a telescopic sleeve fixedly connected between the movable frame and the base, the telescopic sleeve covering the sliding track of the movable frame on the base.

[0011] Compared with the prior art, the present invention has the following advantages: The present invention, through the clamping cooperation between the tray and the pressure plate, the active reversing drive of the tray, and the rotatable structure between the inner tray and the pressure plate, can realize the function of directly switching the cutting edge of the stacked PCB board under continuous clamping, without the need for repeated disassembly and re-alignment, thereby reducing the auxiliary time consumption of this link and significantly shortening the cycle time of the cutting process.

[0012] This utility model adds an auxiliary clamping function to apply local pressure to the front side of the cutting line of the stacked boards before the cutting operation, which effectively suppresses the warping of the board edges caused by the downward pressure of the cutter during the cutting process, avoids dimensional deviations of the edges of each board during cutting, and further ensures the cutting accuracy and batch consistency of the stacked boards.

[0013] This invention utilizes the coordinated operation of a camera and a laser emitter, allowing operators to remotely acquire real-time images and reference markings of the PCB board cutting position from a control console, thus achieving precise positioning and calibration.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] Example: A PCB board cutting device, see reference Figure 1 , Figure 2 , Figure 3 and Figure 5The device includes: a base 1; a control console 2 fixedly installed on the side of the base 1; the device also includes: a base 3 slidably installed inside the base 1 along a horizontal longitudinal direction; a movable frame 7 slidably installed on the base 1 along a horizontal longitudinal direction, the movable frame 7 being fixedly connected to the base 3; a first electric slide rail 5 fixedly installed inside the base 1, the control end of the first electric slide rail 5 being fixedly connected to the base 3 to drive the base 3 and the movable frame 7 to reciprocate back and forth; a motor 4 fixedly installed on the base 3; a tray 6 rotatably installed on the movable frame 7 for carrying PCB boards for cutting; the rotating shaft of the tray 6 is connected to the output shaft of the motor 4 via a gear set to achieve speed reduction and reduce torque damage at the output shaft of the motor 4; a first hydraulic cylinder 8 fixedly installed on the upper part of the movable frame 7; a pressure plate 9 fixedly installed on the telescopic end of the first hydraulic cylinder 8, the axis of the pressure plate 9 coinciding with the axis of the tray 6, and driven vertically by the first hydraulic cylinder 8 to cooperate with the tray 6 to clamp the PCB board; and a device coaxially rotatably installed via a connecting shaft 1001. The inner plate 10 is located on the lower surface of the pressure plate 9; ball bearings 22 are embedded in the outer periphery of the connecting shaft 1001 of the inner plate 10 to reduce the frictional resistance when the inner plate 10 rotates relative to the pressure plate 9; friction pads 23 are fixedly installed on the lower surface of the inner plate 10 and the upper surface of the tray 6 to increase the contact friction with the PCB board; a telescopic sleeve 24 is fixedly installed between the moving frame 7 and the base 1, the telescopic sleeve 24 covers the sliding track of the moving frame 7 on the base 1, preventing chips and dust from entering and ensuring smooth operation of the moving frame 7. The device is characterized by: a mounting bracket 11 fixedly installed at the rear of the base 1; a first pad 12 fixedly installed at the lower part of the mounting bracket 11; a second hydraulic cylinder 13 fixedly installed at the upper part of the mounting bracket 11; a cutter 14 slidably installed vertically on the mounting bracket 11 and fixedly connected to the telescopic end of the second hydraulic cylinder 13, driven by the second hydraulic cylinder 13 to move up and down, cooperating with the first pad 12 to perform cutting; and the first electric slide rail 5, motor 4, first hydraulic cylinder 8, and second hydraulic cylinder 13 are all signal connected to the control console 2.

[0022] During operation, the stacked and aligned PCB boards are placed on tray 6. The first hydraulic cylinder 8 is activated via control console 2, driving the pressure plate 9 downwards to press down on the PCB boards, working together with tray 6 to apply a stable clamping force to the stacked boards. After clamping, the first hydraulic cylinder 8 maintains its pressure, and this clamping force is converted into static friction between the layers of PCB boards, effectively preventing micro-displacement between the boards during the cutting process. Then, the first electric slide rail 5 is activated, driving the base 3 and the moving frame 7 to move backwards, moving the PCB boards and feeding the edge to be cut between the cutter 14 and the first pad 12, ensuring the cutter 14 is directly facing the cutting line of the PCB board. Once in position, the first electric slide rail 5 is closed, and the second hydraulic cylinder 13 is activated to drive the cutter 14 downwards, working in conjunction with the first pad 12 to complete the single-sided cutting.

[0023] After single-sided cutting is completed, the first electric slide rail 5 is activated again to remove the PCB board from under the cutter 14. Then, the motor 4 is activated, driving the tray 6 to rotate via the gear set. Under clamping pressure, the tray 6, through the PCB board, drives the inner tray 10 to rotate smoothly relative to the pressure plate 9, thereby achieving an overall angle switch for the stacked PCB boards and completing the cutting edge reversal. During this process, the clamping force is maintained throughout, and the relative positional relationship between the boards remains unchanged. Afterward, the boards are fed back into the cutting position for cutting, completing the rapid edge-changing operation.

[0024] After all cutting is completed, the second hydraulic cylinder 13 is controlled to move upward to lift the pressure plate 9, releasing the clamp on the PCB board, removing the finished product, and replacing it with the next batch of boards to be processed. The automatic operation sequence of each power source can be set through the control console 2, which can realize semi-automatic or fully automatic cutting cycles, greatly improving the ease of operation.

[0025] This equipment, through the clamping cooperation between tray 6 and pressure plate 9, the active reversing drive of tray 6, and the rotatable structure between inner tray 10 and pressure plate 9, enables stacked PCB boards to directly switch the cutting edge function under continuous clamping, without the need for repeated disassembly and realignment, thereby reducing the auxiliary time consumption in this step and significantly shortening the cycle time of the cutting process.

[0026] The ball bearing 22 structure can effectively reduce the frictional resistance when the inner plate 10 rotates relative to the pressure plate 9, so that the stacked boards can be smoothly reversed in the clamping state; the friction pad 23 increases the friction coefficient of the clamping contact surface, reducing the possibility of the PCB board slipping relative to the pressure plate 9 or the tray 6 in the initial clamping stage, further ensuring the consistency of cutting dimensions and positional accuracy; the telescopic sleeve 24 covers and protects the sliding track of the moving frame 7, preventing chips and dust from entering, ensuring that the moving frame 7 runs smoothly without jamming, thereby maintaining the feeding positioning accuracy and avoiding cutting deviations caused by track contamination.

[0027] See Figure 1 and Figure 3 The device also includes: a second electric slide rail 15 fixedly installed on the side wall of the mounting frame 11, the second electric slide rail 15 being signal-connected to the control console 2; a mounting base 16 slidably installed on the mounting frame 11 vertically, the mounting base 16 being fixed to the control end of the second electric slide rail 15 and being driven by the second electric slide rail 15 to move vertically; a clamping plate 17 fixedly installed on the lower surface of the mounting base 16; and a second pad 18 fixedly installed on the lower part of the mounting frame 11. When the clamping plate 17 moves down with the mounting base 16, it cooperates with the second pad 18 to form a clamping structure, and the clamping surfaces of the two are located on the front side of the cutting surface formed by the cutter 14 and the first pad 12.

[0028] After the PCB board is fed between the cutter 14 and the first pad 12 via the first electric slide rail 5 and positioned at the cutting position, before starting the cutting operation, the control console 2 sends a command to the second electric slide rail 15 to drive the mounting base 16 and the clamping plate 17 to move down synchronously, so that the clamping plate 17 and the second pad 18 provide auxiliary clamping for the PCB board at a position slightly in front of the cutting line. This clamping point is located in front of the cutting area. When the cutter 14 moves down to cut, this local holding force can effectively suppress edge warping of the stacked substrates under the action of the cutting force, thereby avoiding cutting deviation caused by board deformation.

[0029] This equipment, by adding an auxiliary clamping function, applies local pressure to the front side of the cutting line of the stacked boards before the cutting operation, effectively suppressing the warping of the board edges caused by the downward pressure of the cutter 14 during the cutting process, avoiding dimensional deviations at the edges of each board during cutting, and further ensuring the cutting accuracy and batch consistency of the stacked boards.

[0030] See Figure 1 and Figure 4 The equipment also includes: a mounting rod 19 fixedly installed at the front of the mounting frame 11; a camera 20 fixedly installed on the mounting rod 19 for capturing real-time images of the PCB board at the cutting station; and a laser emitter 21 fixedly installed on the mounting rod 19 for projecting marking lines corresponding to the cutting lines onto the surface of the PCB board to visually indicate the cutting position; both the camera 20 and the laser emitter 21 are connected to the control console 2 via signal connection.

[0031] After the PCB board is fed into the cutting station by the first electric slide rail 5, the laser emitter 21 projects a marking line onto the surface of the PCB board. This marking line corresponds precisely in space to the actual cutting line of the cutter 14. The camera 20 captures images of the PCB board cutting process in real time and transmits them to the display screen of the control console 2. The operator can intuitively judge the feeding position and the alignment accuracy of the cutting line through the screen of the control console 2, and complete the precise calibration before cutting. At the same time, all actuators such as electric slide rails, motors 4, and hydraulic cylinders can be remotely controlled through the control console to realize the whole process of visual remote control from feeding, positioning, clamping assistance to cutting and reversing.

[0032] Through the coordinated operation of camera 20 and laser emitter 21, this equipment allows operators to remotely obtain real-time images and marker lines of the PCB board cutting position from the control console 2, enabling precise positioning and calibration. At the same time, the image information from camera 20 provides visualization for the backend, allowing operators to control all power actuators remotely without having to approach the cutting area. This ensures both operational safety and precise control and efficient operation, further enhancing the human-machine interface convenience and automation level of the entire equipment.

[0033] It should be noted that the console 2 is a commonly used control device in existing technology. It has a built-in controller (such as a PLC). This controller performs control operations such as switching and analog signals on multiple electrical devices through preset programs, which will not be described in detail here.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may 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.
