Description

Technical Field

[0001] The invention belongs to the technical field of circuit board grooving, in particular to a circuit board high-efficiency grooving device. Background Art

[0002] A circuit board is a substrate used to support and connect electronic components. Printing technology forms conductive traces on its surface, enabling electrical connections and signal transmission between electronic components. It consists of an insulating substrate such as fiberglass, polyimide, and a copper cladding layer. Conductive traces are formed through an etching process, and pads are designed for mounting electronic components. Irregular holes or slots are then cut into the circuit board. These holes or slots can be linear in shape and have a width equal to the line width. The main functions of slotting include preventing insufficient creepage distance, enhancing insulation strength, improving heat dissipation, reducing the effects of dust and moisture, and optimizing wiring.

[0003] There are several main methods for cutting grooves in circuit boards: V-cutting, drilling, milling, and laser cutting. Laser cutting involves irradiating a laser beam onto the surface of the circuit board, creating a heat-affected zone on the material surface. This rapidly heats the material to its melting or boiling point, causing it to melt or vaporize. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the melted or vaporized material, ultimately forming a groove as the beam moves. Laser cutting offers advantages such as high precision, high efficiency, a small heat-affected zone, strong material adaptability, safe operation, and low cost, making it widely used in industries such as electronic components, circuit boards, semiconductors, microelectronics, and optical devices.

[0004] When using an existing grooving device, the circuit board that needs to be grooved is fixed to the placement platform of the device, and then the device is started. The laser cutter is calibrated with the circuit board so that the laser cutter is aligned with the circuit board. The circuit at the position to be cut is then transmitted to the inside of the device through a computer. The laser cutter is then controlled to move by the device, and the laser cutter is started at the same time to irradiate the laser beam onto the surface of the circuit board to melt or vaporize the material, and finally complete the grooving. However, when the grooving device fixes the circuit board, it is necessary to manually adjust the position of the circuit board, then start the fixing device to fix the circuit board, and then start the device to scan the position and size of the circuit board, scan the position and size of the circuit board into the device, and then calibrate the scanned situation with the circuit at the position to be cut before the circuit board can be grooved. Therefore, before the device can groove the circuit board, it needs to spend a lot of time adjusting the position of the circuit board and scanning the circuit board, which reduces the processing efficiency of the device on the circuit board.

DETAILED DESCRIPTION

[0010] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0011] like Figures 1 to 6 As shown, an efficient grooving device for a circuit board described in an embodiment of the present invention includes a device body 1, an upper surface of the device body 1 is provided with a positioning assembly below the grooving assembly, the positioning assembly includes a placement groove 3 opened on one side of the upper surface of the device body 1, a grooving assembly is provided above the placement groove 3, and a laser cutter 25 is provided inside the grooving assembly, the grooving assembly is used to drive the laser cutter 25 to move above the placement groove 3 to perform grooving operations on the circuit board, a pair of No. 1 slide grooves 31 are opened on both sides of the inner wall of the placement groove 3, a No. 2 slider 34 is slidably connected to the inside of the No. 1 slide groove 31, and a No. 1 connecting plate 35 is fixedly connected between the No. 2 sliders 34 on both sides, one end of the No. 1 slide groove 31 is provided with a driving structure, and a No. 1 bidirectional screw 32 is connected to the inside of the No. 1 slide grooves 31 on both sides for common rotation, and the No. 1 bidirectional screw 32 passes through the No. 2 slider 34 and is threadedly connected to the No. 2 slider 34; The outer surface of the No. 1 connecting plate 35 is provided with a No. 1 groove 36 on one side, and the inner wall upper end of the No. 1 groove 36 is provided with a No. 2 groove 37, and the inner wall upper end of the No. 2 groove 37 is provided with a No. 3 groove 38. The No. 3 groove 38 is slidably connected to the No. 1 slide bar 39, and a pair of No. 2 telescopic rods 312 are fixedly connected to one side of the inner wall of the No. 3 groove 38, and the output end of the No. 2 telescopic rod 312 is fixedly connected to the No. 1 slide bar 39, and the No. 2 groove 37 is slidably connected to the fixed pressure rod 310. The lower surface of the No. 1 slide bar 39 is rotatably connected to a group of No. 1 connecting rods 311, and the lower end of the No. 1 connecting rod 311 is connected to the fixed pressure rod 310 is rotatably connected to the upper surface, a mobile clamping rod 45 is provided just below the No. 1 slide bar 39, and a volley component is provided between the mobile clamping rod 45 and the No. 1 slide bar 39, and the volley component is used to drive the mobile clamping rod 45 and the No. 1 slide bar 39 to move synchronously in the opposite direction. A pair of positioning clamping blocks 52 are slidably connected to the inside of the No. 1 groove 36, and the pair of positioning clamping blocks 52 are located on one side of the No. 2 groove 37 inside the No. 1 groove 36. An adjustment component is provided on one side of the outer surface of the pair of positioning clamping blocks 52, and the adjustment component is located on the side away from the No. 2 groove 37. The adjustment component is used to drive the pair of positioning clamping blocks 52 to move synchronously in the opposite direction; During operation, the circuit board is first placed on the placement platform, and then the position of the circuit board is adjusted to keep the circuit board flat. The fixing device is then started to fix the circuit board on the placement platform, and the scanning device is started to scan the position and size of the circuit board. The circuit at the position to be cut is then transmitted to the inside of the device through a computer, and the position and size of the circuit board are calibrated with the circuit at the cutting position. The laser cutter is then controlled to move through the device, and the laser cutter is started to cut the surface of the circuit board, and finally the grooving is completed. However, by manually placing the circuit board on the placement platform and then clamping the circuit board with a fixing fixture, there is a certain probability that the position of the circuit board placed on the placement platform will be offset each time, and after long-term use, the device will wear out, resulting in a greatly increased probability of the circuit board position offset, resulting in the position of the circuit board being different each time it is placed, so that each time the circuit board is grooving, it needs to be scanned, resulting in the device taking a lot of time to adjust the position of the circuit board and scan the circuit board before grooving a large number of circuit boards of the same specification, which reduces the processing efficiency of the device on the circuit board.

[0012] When in use, the circuit board is placed between the two No. 1 connecting plates 35 in the placement groove 3, and then the driving structure is started to drive the two No. 1 bidirectional screws 32 to rotate simultaneously, and then the No. 2 slider 34 and the No. 1 bidirectional screw 32 cooperate to drive the two No. 1 connecting plates 35 to move synchronously toward the circuit board, so that one side of the circuit board is inserted into the No. 1 groove 36 on one side, thereby pushing the circuit board to move in the horizontal direction in the placement groove 3, and then the other side of the circuit board is inserted into the No. 1 groove 36 on the other side, so that the circuit board moves to the horizontal middle position in the placement groove 3, and at the same time, the circuit board is clamped from the left and right sides, and then the adjustment component is started to push the circuit board to move in the longitudinal direction in the placement groove 3. , so that the circuit board moves to the longitudinal middle position in the placement slot 3, thereby automatically moving the circuit board to the center position in the placement slot 3, and then starting the scanning device to scan the circuit board, and transmitting the information scan of the circuit board to the control cabinet on the device, so that the positioning component automatically moves the circuit board to the center position in the placement slot 3, resulting in the subsequent circuit boards of the same specification being cut to be moved to the center position in the placement slot 3, ensuring that large quantities of circuit boards of the same specification can be moved to the same position each time they are placed in the placement slot 3, so that the scanning device only needs to scan the first circuit board of the same specification, thereby improving the processing efficiency of the device for large quantities of circuit boards of the same specification. After that, the second extension rod 312 is shortened, and the second extension rod 311 is driven to move in the third groove 38, and the second extension rod 312 is connected to the second extension rod 311 and the fixed pressure rod 310 by the rotation connection of the second extension rod 311. The second extension rod 312 is connected to the second extension rod 311 by the rotation connection of the second extension rod 311. The second extension rod 312 is connected to the second extension rod 311 and the fixed pressure rod 310. The connection state of the second extension rod 311 and the fixed pressure rod 310 is changed to a vertical state, increasing the distance between the first extension rod 39 and the fixed pressure rod 310, thereby pushing the fixed pressure rod 310 to move downward in the second groove 37, so that the fixed pressure rod 310 is close to the circuit board, thereby fixing the circuit board in the two first grooves 36, preventing the circuit board from shaking during laser grooving of the circuit board, resulting in the deviation of the laser grooving position, and affecting the yield rate of laser grooving of the circuit board. Then, the computer transmits the circuits at the locations on the circuit board where grooves need to be cut to the control cabinet on the device, thereby calibrating the scanning information of the circuit board and the circuits at the groove locations to determine the movement route of the laser beam for cutting grooves on the circuit board. The grooving assembly is then activated to control the laser cutter 25, which is moved above the circuit board. The laser cutter 25 is then activated to irradiate the laser beam onto the circuit board. At the same time, the grooving assembly is activated to control the movement of the laser cutter 25, thereby moving the laser beam to cut the circuit board, and finally completing the grooving. Moreover, by driving the two No. 1 connecting plates 35 to move, different specifications can be positioned and fixed, thereby improving the applicability of the positioning assembly.

[0013] like Figures 1 to 5 As shown, both sides of the upper end of the inner wall of the second groove 37 are fixedly connected with positioning slides 313, and the two positioning slides 313 are located on both sides of the third groove 38. The lower ends of the two positioning slides 313 are fixedly connected to the lower end of the inner wall of the first groove 36, and the positioning slides 313 all pass through the fixed pressure rod 310 and are slidably connected to the fixed pressure rod 310; During operation, the two positioning slide bars 313 are slidably connected to the fixed pressure bar 310 to limit the movement of the fixed pressure bar 310, thereby preventing the fixed pressure bar 310 from shaking during movement and improving the stability of the fixed pressure bar 310 moving up and down in the second groove 37.

[0014] like Figures 3 and 4 When the cam 331 is in the unlock position, the gear 332 is locked and the two gears 331, 332 are locked. As shown in FIG, the driving structure includes a second bevel gear 335 fixedly connected to one end of the two No. 1 slide grooves 31, a No. 1 mounting groove 33 is opened in the device body 1, which is respectively adapted to the two No. 2 bevel gears 335, and the two No. 2 bevel gears 335 both extend into the No. 1 mounting groove 33, a No. 2 mounting groove 331 is opened on one side of the outer surface of the device body 1, and the No. 2 mounting groove 331 and the two No. 1 mounting grooves 333 are located on the same straight line, and a No. 1 motor 332 is fixedly connected to one side of the inner wall of the No. 2 mounting groove 331, and a rotating shaft 333 is fixedly connected to the output end of the No. 1 motor 332, and the rotating shaft 333 passes through the two No. 1 mounting grooves 33, and the outer circumferential surface of the rotating shaft 333 is located in the two No. 1 mounting grooves 33 and is fixedly connected to the No. 1 bevel gear 334, and the two No. 1 bevel gears 334 are respectively meshed with the two No. 2 bevel gears 335, and a cleaning component is provided on the outer surface of the rotating shaft 333; During operation, the No. 1 motor 332 inside the No. 2 mounting slot 331 is started to drive the rotating shaft 333 to rotate, thereby driving the two No. 1 bevel gears 334 to rotate synchronously, and then the two No. 1 bevel gears 334 are respectively engaged with the two No. 2 bevel gears 335 to rotate synchronously, thereby driving the two No. 1 bidirectional screws 32 to rotate synchronously, and then driving the two No. 1 connecting plates 35 to move synchronously, and the two No. 1 bidirectional screws 32 are driven to rotate by a single No. 1 motor 332, thereby ensuring that the two No. 1 bidirectional screws 32 rotate synchronously at the same speed, improving the stability of the movement of the two No. 1 bidirectional screws 32, and at the same time improving the accuracy of controlling the two No. 1 bidirectional screws 32. Moreover, through the setting of a single No. 1 motor 332, when the single No. 1 motor 332 is damaged, the two No. 1 bidirectional screws 32 stop running at the same time. However, when the two No. 1 bidirectional screws 32 are driven to run at the same time by two driving devices, when the single driving device is damaged, one No. 1 bidirectional screw 32 stops running while the other No. 1 bidirectional screw 32 is still running, resulting in more damage to the positioning component and causing more losses.

[0015] like Figures 1 to 2As shown, the grooving assembly includes a No. 1 electric slide rail 2 fixedly connected to both sides of the upper surface of the device body 1, and the No. 1 electric slide rail 2 is located on both sides of the placement groove 3, and the interiors of the two No. 1 electric slide rails 2 are slidably connected to a sliding frame 21, and the upper ends of the outer surfaces of the two sliding frames 21 are commonly fixedly connected to a No. 2 electric slide rail 22, and the interior of the No. 2 electric slide rail 22 is slidably connected to a No. 1 slider 23, and the No. 1 slider 23 is fixedly connected to four No. 1 telescopic rods 24 evenly distributed in a rectangular shape, and the lower ends of the four No. 1 telescopic rods 24 are commonly fixedly connected to the laser cutter 25; During operation, after the positioning assembly fixes the circuit board in the center position of the placement slot 3, the No. 1 electric slide rail 2 is started to drive the two sliding frames 21 to move, thereby driving the No. 2 electric slide rail 22 to move longitudinally, and at the same time driving the laser cutter 25 to move longitudinally, and then the No. 2 electric slide rail 22 is started to drive the No. 1 slider 23 to move laterally, thereby driving the laser cutter 25 to move laterally, so that the laser cutter 25 can be moved to any position above the circuit board.
