Description

Technical Field

[0002] PCB, whose full name is Printed Circuit Board, that is, printed circuit board, is also known as printed wiring board. It is a support for electronic components and at the same time a carrier for electrical connection of electronic components. Since it is made by electronic printing technology, it is named "printed" circuit board. For fixed electronic components, the principle of the shortest connection between them is an important layout. And the layout design includes the size of the layout, the layout of devices, the position of input and output ports, the design of wiring, etc. The manufacturing process of PCB involves multiple steps, including drawing design, material preparation, drilling, electroplating, circuit production, solder mask, character printing, surface treatment, assembly, testing and packaging, etc. Each step requires precise operation and strict quality control to ensure the performance and reliability of the final product.

[0003] During the processing of PCB, in order to remove burrs and uneven parts on the edge of the PCB board, improve the smoothness and beauty of the edge, or ensure that the size of the PCB board meets the design requirements, and provide an accurate reference for subsequent assembly and connection, cutting or grooving operations of sawing edge processing will be carried out, and for this purpose, a sawing edge device will be used for cutting and sawing. The sawing edge device is a mechanical device specifically used for edge trimming or cutting of materials such as plates, wood, aluminum alloy, and plastic.

[0004] At the present stage, there is a PCB board processing and cutting device. For example, a PCB board cutting device disclosed in Patent Application No. CN201920584913.0. This utility model solves the problems that although scales are provided at both the front and rear ends of the existing PCB board cutting machine, its usability is not high, it is not convenient for the PCB board cutting machine to cut at multiple angles and in multiple directions, and the exposed saw blade of the PCB board cutting machine is likely to cause injury to the staff. By improving and optimizing the structure of the PCB board cutting machine, the usability of the scales at both the front and rear ends of the PCB board cutting machine is high, and it is convenient for the PCB board cutting machine to cut the PCB board in multiple directions and at multiple angles.

[0005] However, there are problems in the use of this device. First of all, it cannot process multiple workpieces of the same specification simultaneously. During the manual cutting process of generally small-sized PCB boards, it is necessary to repeatedly load and unload, and repeatedly confirm the size of the required cutting edge. This is inconvenient for clamping and fixing multiple workpieces of the same specification, resulting in low processing efficiency. Summary of the Invention

[0014] A further technical solution of the present application: The clamping member includes a receiving groove opened on the inner side of the clamping member, a frame slidably mounted inside the receiving groove, and a strip mounted at the center position of the upper end of the frame. A top groove is opened at the inner top of the receiving groove. An adjusting cylinder is mounted in the top groove. The strip is inserted and matched in the top groove. And the end of the adjusting cylinder is connected to the end face of the strip. The inner side of the frame is a hollow structure. A plurality of partition plates are symmetrically arranged on both sides below the frame. A receiving gap is formed between the plurality of partition plates. A moving groove is also opened at the position of the upper end face of the frame corresponding to the receiving gap. Two moving blocks are slidably connected to both ends inside the moving groove. An extension block is connected below a single moving block. The extension block can be received into the receiving gap; Type grooves are symmetrically opened on both sides of the strip.

[0015] A further technical solution of the present application: rollers are sleeved on the lower ends of the resilient blocks and the lower ends of the rotating shafts, and the rollers rotate inside the embedded grooves; The top cross-section of the part of the extension block extending outside the storage gap is a parallelogram, and the side close to the clamping member is an inclined side.

[0016] A sawing edge device with an automatic control system and its method, the method comprising the following steps: Step 1, adjust the position of the clamping assembly on the tabletop and the distance between the clamping mechanisms in the clamping assembly to meet the sawing edge processing of workpieces with different widths. When placing, the side to be cut should be on the sawing groove. When adjusting, first slide the clamping assembly and push the whole clamping assembly on the convex rib to adjust the size of the side of the workpiece to be cut, and then adjust the distance between the clamping mechanisms inside the clamping assembly; Step 2, when adjusting the distance between the clamping mechanisms, the first driving motor works to drive the driving screw to rotate, so as to realize the rotation of the active block. Since the two sides of the active block are slidably connected to the sliding rod, the rotation of the active block is restricted in this way, and the displacement of the active block is realized. During the displacement of the active block, the auxiliary rods connected thereto move along, and at the same time, the auxiliary rods drive the respective connected rotating rods to move. The rotating rods will rotate along the rotating columns, and the angles between them change, shrink or elongate, and change following the moving direction of the active block. At the same time, during the movement of multiple rotating rods, the driven blocks connected thereto will be driven to move. The driven block closest to the first side plate and the upper rotating rod will drive the auxiliary rod below the first side plate to rotate outside the rotating column to limit the maximum expansion length. In this way, the distance between multiple driven blocks is adjusted. The driven blocks are displaced along the sliding rod, and at the same time, the clamping mechanisms on the sides of the driven blocks and the active block follow the displacement to complete the distance adjustment; Step 3, place multiple workpieces to be sawed on the gaps formed by multiple clamping mechanisms on the tabletop, ensure that the side to be sawed is outside the sawing groove, and then the first driving motor works to drive the active block and the driven block to move closer, so that the clamping members in the clamping mechanism move closer to each other. Subsequently, the clamping members work to finely adjust the length, extend outward or contract inward to ensure that the clamping members can completely fit on both sides of the workpiece; Step 4, through the work of the sawing edge assembly, the second driving motor works to drive the driving belt to rotate. When the driving belt rotates, it drives the first transmission shaft to rotate. When the first transmission shaft rotates, it drives the outer transmission belt to rotate, so as to realize the movement of the transmission belt driving the belt buckle and the third mounting plate. The belt buckle and the third mounting plate move along the track of the guide rail to drive the saw blade to move. At the same time, the third driving motor works to drive the saw blade to rotate for moving sawing.

[0017] Adopting the technical solution provided by the present invention, compared with the prior art, it has the following beneficial effects: By setting a processing table, a clamping assembly and a sawing edge assembly, firstly, the present invention can adjust the distance between the clamping assembly and the saw slot to adjust the size of the sawing edge. The operation is convenient, and the approximate length required for fixing the workpiece can be quickly adjusted, which is convenient for quick feeding. Secondly, the multiple clamping mechanisms connected to the outside of the sawing edge assembly can be quickly disassembled, and the replacement is convenient, which is convenient for subsequent maintenance of the clamping parts. At the same time, the clamping parts can extend again after clamping both sides of the workpiece to prevent fine adjustment and comprehensively fix the workpiece. The multiple clamping mechanisms can be operated once to adjust multiple gaps, meeting the clamping and fixing of multiple workpieces of the same specification, and greatly improving the efficiency.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. The present invention will be further described below in conjunction with the embodiments.

[0021] Please refer to Figures 1 to 11 , in an embodiment of the present application, a sawing edge device with an automatic control system includes a processing table 1. The processing table 1 is composed of a support frame 105 and a tabletop 101 arranged at the top. An installation cavity is formed in the support frame 105, and a sawing edge assembly 3 is arranged in the installation cavity. A saw slot 102 is opened on the tabletop 101, and the sawing edge assembly 3 extends to the tabletop 101 through the saw slot 102; Two convex ribs 106 are arranged in parallel at both ends of the saw slot 102 on the tabletop 101, and a slidable clamping assembly 2 is arranged between the two convex ribs 106; The clamping assembly 2 includes a first side plate 201 and a second side plate 208 which are arranged mirror-symmetrically, and a driving screw 217 connected between the first side plate 201 and the second side plate 208. An installation seat 207 is further arranged outside the second side plate 208, and a first driving motor 211 connected to the driving screw 217 is arranged on the installation seat 207. Two sliding rods 204 are symmetrically arranged on both sides of the driving screw 217 between the first side plate 201 and the second side plate 208. One end of the driving screw 217 close to the second side plate 208 is threadedly connected with a driving block 202, and both ends of the driving block 202 are slidably arranged on the two sliding rods 204. A plurality of driven blocks 206 are further slidably connected between the two sliding rods 204 and the driving screw 217 outside the driving block 202 and the first side plate 201; Rotating columns 210 are arranged at the centers of the upper ends of the driving block 202 and the driven blocks 206 and below the upper end of the first side plate 201. A rotating rod 203 is connected to the driven block 206 through the rotating column 210. The ends of the rotating rods 203 are sequentially connected between the plurality of driven blocks 206 for splicing. One end of a secondary rod 209 is connected to the driving block 202 and below the upper end of the first side plate 201 through the rotating column 210, and the other ends of the two secondary rods 209 are respectively connected to the ends of the two outermost rotating rods 203. Clamping mechanisms are connected to the side end faces of the driving block 202 and the driven blocks 206, and the lower sides of the clamping mechanisms are attached to the upper end face of the table 101.

[0022] This embodiment is implemented as follows: During actual use, first, adjust the position of the clamping assembly 2 on the table 101 and the spacing between the clamping mechanisms in the clamping assembly 2 to meet the sawing edge processing of workpieces of different sizes. When placing, the side to be cut should be located on the saw slot 102. When adjusting, first, slide the clamping assembly 2 to push the whole clamping assembly 2 on the convex rib 106 to roughly adjust the approximate side length of the workpiece to be cut and perform rough fixation; It should be noted that at this time, it is necessary to ensure that one end of the workpiece is in full contact with the side surface of the clamping assembly 2, and then adjust the interval of the clamping mechanism inside the clamping assembly 2; when adjusting the interval of the clamping mechanism, the first driving motor 211 works to drive the driving screw 217 to rotate, so as to realize the rotation of the active block 202. Since both sides of the active block 202 are slidably connected to the slide rod 204, the rotation of the active block 202 is restricted in this way, and the displacement of the active block 202 is realized. During the displacement of the active block 202, the auxiliary rod 209 connected thereto moves accordingly. At the same time, the auxiliary rod 209 drives the respective connected rotating rods 203 to move. The rotating rod 203 will rotate along the rotating column 210, and the angle between the two changes, contracts or elongates, and follows the change of the moving direction of the active block 202. At the same time, during the movement of the multiple rotating rods 203, the respective connected driven blocks 206 will be driven to move. The driven block 206 closest to the first side plate 201 and the upper rotating rod 203 will drive the auxiliary rod 209 below the first side plate 201 to rotate outside the rotating column 210 to limit the maximum expansion length. In this way, the interval adjustment between the multiple driven blocks 206 is completed. The driven block 206 moves along the slide rod 204, and at the same time, the clamping mechanism on the side surfaces of the driven block 206 and the active block 202 follows the displacement to complete the interval adjustment.

[0023] Subsequently, the clamping member 205 can work and extend from the inside of the clamping member 205 to ensure that the two sides of the workpiece can be completely clamped by the clamping member 205, reducing shaking.

[0024] Please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , as a preferred embodiment of the present application, the clamping mechanism includes splicing grooves 213 opened on the side end faces of the active block 202 and the driven block 206, and splicing blocks 215 are inserted into the splicing grooves 213. A magnetic sheet 216 is provided at the end of the splicing block 215, and the magnetic sheet 216 can be magnetically adsorbed to the inner bottom of the splicing groove 213. The outer side of the lower end of the splicing block 215 is connected with a clamping member 205; Furthermore, positioning grooves 212 are symmetrically opened on both sides of the splicing groove 213 near the opening end, and positioning blocks 214 that are spliced with the positioning grooves 212 are symmetrically arranged on both sides of the splicing block 215.

[0025] This embodiment is implemented as follows: During actual use, since the side shapes of PCB workpieces of different specifications are not exactly the same, in order to fix PCB workpieces of different shapes, clamping members 205 of multiple shapes can be made and connected to the splicing block 215. The splicing block 215 is used in cooperation with the magnetic sheet 216 and is magnetically adsorbed in the splicing groove 213 to achieve rapid splicing installation and fixation. At the same time, the positioning groove 212 and the positioning block 214 are used in cooperation, which can reduce the situation of the clamping member 205 shaking and is more stable.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 , as a preferred embodiment of the present application, the driving assembly includes a first mounting plate 305, a second mounting plate 312, and a third mounting plate 315. The first mounting plate 305 is disposed in the middle section of the mounting cavity. At the left and right ends of the upper end surface of the first mounting plate 305, a first transmission shaft 307 and a second transmission shaft 308 are respectively provided. The first transmission shaft 307 and the second transmission shaft 308 are connected by a transmission belt 303. On both sides of the upper end surface of the first mounting plate 305, two guide rails 313 are provided. Two sliders 314 are slidably disposed outside a single guide rail 313, and the third mounting plate 315 is mounted on the upper ends of the four sliding blocks. The third mounting plate 315 is located below the transmission belt 303. The third mounting plate 315 is connected to the transmission belt 303 through a buckle 316 provided at the upper end. An expansion cylinder 309 is provided above the buckle 316, and the second mounting plate 312 is mounted on the upper end of the expansion cylinder 309. A third driving motor 310 is provided on the upper end surface of the second mounting plate 312. The power output shaft of the third driving motor 310 is connected to a saw blade 304, and the saw blade 304 extends to the table 101 through a saw slot 102.

[0027] Furthermore, limit posts 311 are provided at the four top corner positions of the upper end surface of the third mounting plate 315, and the upper ends of the limit posts 311 are inserted through the four tops of the second mounting plate 312.

[0028] Furthermore, the driving assembly further includes a bottom plate 306 mounted at the bottom of the mounting cavity. A second driving motor 301 is provided on the bottom plate 306. The outer side of the power output shaft of the second driving motor 301 is connected to a driving belt 302, and the other end of the driving belt 302 is connected to the outer side of the first transmission shaft 307.

[0029] This embodiment is implemented as follows. When the edge-sawing assembly 3 works, the second drive motor 301 inside it works to drive the drive belt 302 to rotate. When the drive belt 302 rotates, it drives the first transmission shaft 307 to rotate. When the first transmission shaft 307 rotates, it drives the outer transmission belt 303 to rotate, realizing that the transmission belt 303 drives the buckle 316 and the third mounting plate 315 to move. The buckle 316 and the third mounting plate 315 move along the track of the guide rail 313, driving the saw blade 304 to move. At the same time, the third drive motor 310 works to drive the saw blade 304 to rotate for moving edge-sawing. Meanwhile, the telescopic cylinder 309 can lift the height of the second mounting plate 312, the third drive motor 310 and the saw blade 304, controlling the height of the saw blade 304 extending out of the saw slot 102 to ensure that it can meet the requirements for cutting workpieces of different thicknesses. During the process of lifting the height of the second mounting plate 312, it will move along four limit posts 311 to realize height movement, making the lifting more stable. Driving the first transmission shaft 307 to rotate by the second drive motor 301 can ensure that when there is a huge resistance during edge-sawing, the belt slips, preventing the situation of multiple drive motors being overloaded and damaged.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 3 In this embodiment, a protective cover 104 is provided at one end of the saw slot 102 on the upper end surface of the table 101.

[0031] Furthermore, a control switch 103 is also provided on the upper end surface of the table 101 outside the protective cover 104, and the control switch 103 is electrically connected to the first drive motor 211, the second drive motor 301 and the third drive motor 310.

[0032] In practical applications, the protective cover 104 can protect the saw blade 304 when not cutting, preventing accidental injury and being safer and more practical. The control switch 103 can control the first drive motor 211, the second drive motor 301 and the third drive motor 310, making the operation convenient.

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11, as a preferred embodiment of the present application, the clamping member 205 includes a receiving groove 9 opened on the inner side of the clamping member 205, a frame 8 slidably installed inside the receiving groove 9, and a strip 5 installed at the center position of the upper end of the frame 8. A top groove 7 is opened at the top inside the receiving groove 9, and an adjusting cylinder 4 is installed in the top groove 7. The strip 5 is fitted and inserted into the top groove 7, and the end of the adjusting cylinder 4 is connected to the end face of the strip 5. The inner side of the frame 8 is a hollow structure, and a plurality of partition plates 12 are symmetrically arranged on both sides below the frame 8. A receiving gap is formed between the plurality of partition plates 12. A moving groove 10 is also opened on the upper end face of the frame 8 corresponding to the position of the receiving gap. Two moving blocks 11 are slidably connected to both ends inside the moving groove 10. An extension block 6 is connected below a single moving block 11, and the extension block 6 can be received into the receiving gap; Type grooves 13 are symmetrically opened on both sides of the strip 5. An embedded groove 15 is opened at the position corresponding to the moving groove 10 inside a single type groove 13. A resilient block 17 and a rotating shaft 19 are sequentially slidably connected inside the embedded groove 15. One end of a spring 16 is connected to the end of the resilient block 17 away from the rotating shaft 19, and the other end of the spring 16 is connected to the inside of the embedded groove 15. One end of a connecting rod 14 is rotatably connected to the outside of the rotating shaft 19, and the other end of the connecting rod 14 is rotatably connected above the moving block 11 inside the corresponding moving groove 10.

[0034] Further, rollers 18 are sleeved on the lower ends of the resilient block 17 and the rotating shaft 19, and the rollers 18 rotate inside the embedded groove 15; The top cross-section of the part of the extension block 6 extending outside the receiving gap is a parallelogram, and the side close to the clamping member 205 is an inclined side.

[0035] This embodiment is implemented as follows. Since when the clamping assembly 2 fixed the workpiece in the previous step, only the length of the clamping assembly 2 was roughly set, and when the workpiece entered the multiple clamping mechanisms inside the clamping assembly 2, it might not be parallel to the clamping member 205 in the clamping mechanism, but inclined. This would result in the length of the workpiece being longer or shorter than the length of the clamping member 205 after the clamping member 205 closed. At this time, the length of the clamping member 205 needed to be adjusted; During adjustment, the strip 5 is pushed out by the adjusting cylinder 4 to drive the frame 8 to move. After one end of the frame 8 moves to the outside of the clamping rod, the connecting rod 14 disengages from the top groove 7. At this time, the spring 16 releases force and pushes out the resilient block 17. The resilient block 17 slides in the embedded groove 15 and pushes the rotating shaft 19 to the end of the embedded groove 15. During this process, the other end of the connecting rod 14 will push the moving block 11 to both ends of the moving groove 10, so as to push out the extension block 6. After the extension block 6 is pushed out, it is parallel to both sides of the non-adjustable part of the clamping member 205, realizing the clamping of the workpiece; It should be noted that the usage state of the clamping member 205 can be adjusted by itself. When the clamping member 205 clamps the workpiece roughly for the first time, it can be in the fully extended state or in the fully retracted state, which depends on workpieces of different lengths and the needs of the user.

[0036] When the clamping member 205 is in the fully extended state when clamping the workpiece roughly for the first time, the subsequent adjustment is to recycle the redundant part of the clamping member 205. Recycling the clamping member 205 only requires one operation of adjusting the cylinder 4 to achieve the overall movement of the extension block 6, the profile bar 5, and the profile frame 8, and ensure that the unrecovered part can still be parallel to both sides of the non-adjustable part of the clamping frame. At the same time, for a single extension block 6 and its associated components, they can be customized to be smaller or larger in length, which depends on different usage scenarios and the precision of the machined workpiece.

[0037] Please refer to Figures 1 to 11 , a sawing edge device with an automatic control system and its method according to the present invention, the method comprising the following steps: Step 1: Adjust the position of the clamping assembly 2 on the table 101 and the spacing between the clamping mechanisms in the clamping assembly 2 to meet the sawing edge processing of workpieces of different widths. When placing, the side to be cut should be on the saw slot 102. When adjusting, first slide the clamping assembly 2 to push the whole clamping assembly 2 on the convex rib 106 to adjust the size of the side of the workpiece to be cut, and then adjust the spacing of the clamping mechanisms inside the clamping assembly 2; Step 2: When adjusting the spacing of the clamping mechanisms, the first driving motor 211 works to drive the driving screw 217 to rotate, so as to realize the rotation of the active block 202. Since both sides of the active block 202 are slidably connected to the slide rod 204, the rotation of the active block 202 is restricted in this way, and the displacement of the active block 202 is realized. During the displacement of the active block 202, the secondary rod 209 connected thereto moves accordingly. At the same time, the secondary rod 209 drives the respective connected rotating rods 203 to move. The rotating rods 203 will rotate around the rotating column 210, and the angles between them change, shrink or stretch, following the change of the moving direction of the active block 202. At the same time, during the movement of multiple rotating rods 203, they will drive the respective connected driven blocks 206 to move accordingly. The driven block 206 closest to the first side plate 201 and the upper rotating rod 203 will drive the secondary rod 209 below the first side plate 201 to rotate outside the rotating column 210 to limit the maximum expansion length. In this way, the spacing adjustment between multiple driven blocks 206 is completed. The driven blocks 206 are displaced along the slide rod 204, and at the same time, the clamping mechanisms on the sides of the driven blocks 206 and the active block 202 follow the displacement to complete the spacing adjustment; Step 3: Place multiple workpieces to be edge-sawed in the gaps formed by multiple clamping mechanisms on the tabletop 101, ensuring that the side to be edge-sawed is outside the saw slot 102. Then, operate the first driving motor 211 to drive the active block 202 and the driven block 206 to move closer, so that the clamping members 205 within the clamping mechanism move closer to each other. Subsequently, the clamping members 205 operate to finely adjust the length, extend outward or contract inward to ensure that the clamping members 205 can completely fit on both sides of the workpiece. Step 4: Operate the edge-sawing assembly 3. The second driving motor 301 operates to drive the driving belt 302 to rotate. When the driving belt 302 rotates, it drives the first transmission shaft 307 to rotate. When the first transmission shaft 307 rotates, it drives the outer transmission belt 303 to rotate, enabling the transmission belt 303 to drive the belt buckle 316 and the third mounting plate 315 to move. The belt buckle 316 and the third mounting plate 315 move along the track of the guide rail 313, driving the saw blade 304 to move. At the same time, the third driving motor 310 operates to drive the saw blade 304 to rotate for moving edge-sawing. In summary, by providing a processing table, a clamping assembly, and an edge-sawing assembly, first, the present invention can adjust the size of the edge-sawing by adjusting the distance between the clamping assembly and the saw slot, with convenient operation. Second, the multiple clamping mechanisms connected to the outside of the edge-sawing assembly can be quickly disassembled, with convenient replacement, facilitating subsequent maintenance of the clamping members. Moreover, the adjustment of the intervals between multiple edge-sawing mechanisms is simple, and multiple intervals can be adjusted in one operation to meet the clamping and fixing of multiple workpieces of the same specification, greatly improving the efficiency.
