[0002] PCB, or printed circuit board, is a thin plate used for wiring and fixing circuit components in electronic devices. It is composed of a substrate (such as glass fiber reinforced plastic) and copper foil, on which circuit paths are made through printing technology. It is mainly used for the assembly and interconnection of electronic devices, and plays the role of circuit connection and supporting electronic components.

[0003] When the existing shearing equipment is used, the complete PCB template needs to be cut to obtain the PCB board of the required area size. In the production process of the PCB board, the operator often directly holds the whole PCB template by hand and places it under the cutter. The cutter cuts the PCB template. After a small part of the whole PCB template is cut off, due to specific needs, sometimes the worker continues to push the PCB template to the cutter and cuts it again. Since the whole process is operated by hand, this will cause safety hazards. Especially when the shearing amount is large, there are often only a few commonly used shearing sizes, and the length is prone to errors and fatigue.

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0021] like Figure 1-Figure 9 As shown, a shearing device for PCB board manufacturing includes a base plate 10 and a support frame 20, the base plate 10 is fixed on the production equipment, the support frame 20 is fixed above the base plate 10, and a plurality of mounting grooves 21 are opened at the bottom of the support frame 20; The transmission mechanism 30 includes a transmission plate 31 disposed on the support frame 20, and a fixing assembly 32 rotatably disposed on the support frame 20. A transmission assembly 33 is disposed in the transmission plate 31, and is used to transmit the PCB board by cooperating with the fixing assembly 32. The shearing mechanism 40 includes a shearing plate assembly 41 and a cutting plate assembly 42 which are slidably disposed at the bottom of the support frame 20 and are used to shear the PCB board to ensure that a complete PCB board can be obtained; The collecting assembly 50 includes a collecting frame 51 disposed above the bottom plate 10, and is used to support the PCB board after the board is cut, so as to facilitate the board cutting assembly 42 to perform the board cutting work; Among them, the PCB board is transmitted by the transmission mechanism 30, and the PCB board is sheared by the shearing assembly 41 arranged at the bottom of the support frame 20. Then, the sheared PCB board is transmitted to the collection rack 51 by the transmission mechanism 30, and then it is cut into a formed PCB board by the cutting assembly 42. Then, the sheared PCB board is transmitted to the collection box through the collection track 52 set at the other end of the collection rack 51.

[0022] It should be noted that the present invention is used in conjunction with a numerical control center, and infrared sensors (not shown in the figure) are provided on the transmission plate 31 and the driving plate 412, which are used to detect the position where the shearing plate needs to be cut on the PCB board, and are electrically connected to the numerical control center. Among them, the infrared sensor on the transmission plate 31 will detect the distance between the shearing plate positions, and then send a signal to the infrared sensor on the driving plate 412 through the numerical control center. When the infrared sensor on the driving plate 412 detects the shearing plate position on the PCB board, the transmission motor 332 will be controlled by the numerical control center to stop working, and then the shearing plate motor 413 will be started to shear the plate. Among them, when it is detected that the shearing plate position on the PCB template has changed, a control signal will be sent to the driving motor 411 through the numerical control center, so that it drives the driving plate 412 and the shearing knife 414 to move to the shearing plate position to complete the shearing plate work. Specifically, an infrared sensor is also provided on the guide plate 424, which is used to detect the position where the plate needs to be cut, so that the cutting plate assembly 42 can perform accurate cutting.

[0023] In this embodiment, the base plate 10 is used to connect with the production equipment, and can provide a stable working platform for the shearing device. By fixing the support frame 20 above the base plate 10, other structures in the shearing device can be supported and fixed, ensuring that effective work can be performed on the support frame 20. A plurality of mounting grooves 21 are provided at the bottom of the support frame 20 for placing the mounting rails 22, which can provide stable support and paths for the movement of the shearing mechanism 40. The transmission mechanism 30 is used to automatically transmit the PCB board, ensuring that the PCB board can be orderly transmitted to the shearing mechanism 40 for shearing. The transmission mechanism 30 includes a transmission plate 31 fixedly arranged on one side of the support frame 20, and the PCB board can be supported by the transmission plate 31 to ensure stability during the transmission work. At the same time, the transmission plate 31 can provide guidance for the movement of the PCB board, ensuring that the PCB board can be effectively guided to the shearing area. A transmission component 33 is provided in the transmission plate 31, which can provide power for the movement of the PCB board, so that it can be effectively transmitted on the transmission plate 31. Among them, the fixing assembly 32 slidingly arranged on the support frame 20 can be used in conjunction with the transmission assembly 33. The fixing assembly 32 can fix the PCB board during transmission, and can prevent the PCB board from being separated from the transmission plate 31 by the external force when the power of the transmission assembly 33 acts on the bottom of the PCB board, thereby ensuring the stable transportation of the PCB board during the shearing process and reducing the error. The shearing mechanism 40 is used to shear and cut the PCB board, ensuring that the finished PCB board can be separated from the overall template. By sliding the shearing assembly 41 and the cutting assembly 42 on the mounting track 22, the overall template can be sheared and cut respectively. The collecting assembly 50 is used to collect the sheared PCB board. At the same time, the collecting rack 51 in the collecting assembly 50 can cooperate with the shearing mechanism 40 to support and fix the PCB board, which is convenient for shearing and cutting. At the same time, the collection track 52 set in the collecting rack 51 can be used to transfer and collect the cut PCB board, so that the completed PCB board is transferred to the collection box, which is convenient for subsequent work.

[0024] like Figure 2 , Figure 4 , Figure 5As shown, a transmission slot 311 is provided on the transmission plate 31 for placing the transmission assembly 33, so that the power of the transmission assembly 33 can act on the bottom of the PCB board placed on the transmission plate 31. The transmission assembly 33 includes a connecting plate 331 fixedly arranged on one side of the support frame 20, which is used to fix the transmission motor 332 to ensure the stable use of the transmission motor 332. A transmission wheel 333 is connected to the output end of the transmission motor 332 through a transmission assembly 34, and the transmission wheel 333 can be driven to rotate through the transmission assembly 34 after the transmission motor 332 is started. A balancing wheel 335 is fixedly connected to the outer side of the transmission wheel 333 through a transmission belt 334, and the balancing wheel 335 can ensure that the transmission belt 334 and the transmission plate 31 are in parallel planes, so that the power of the transmission belt 334 can effectively act on the PCB board. It should be noted that the transmission belt 334 is located in the transmission slot 311 and can directly contact the bottom of the PCB board. When the transmission motor 332 drives the transmission wheel 333 through the transmission assembly 34, the transmission wheel 333 will directly drive the transmission belt 334, so that the power acts on the bottom of the PCB board, driving the PCB board to move on the transmission plate 31.

[0025] like Figure 4 , Figure 5 As shown, the transmission assembly 34 includes an active transmission wheel 341, and the active transmission wheel 341 is fixedly arranged at the output end of the transmission motor 332, so that the power generated by the transmission motor 332 can be directly received. By arranging a transmission belt 342 on the outside of the active transmission wheel 341, and the transmission belt 342 is connected to the driven transmission wheel 343, the power received by the active transmission wheel 341 can be effectively transmitted to the driven transmission wheel 343 through the transmission belt 342. Among them, the driven transmission wheel 343 is fixedly connected to the transmission wheel 333 through the transmission roller 344, and then the power can be directly transmitted to the transmission wheel 333 through the transmission roller 344, so that the transmission wheel 333 is driven to rotate. It should be noted that a rotation hole is opened on the support frame 20, and the transmission roller 344 is rotatably arranged in the rotation hole. The transmission roller 344 can be supported by the support frame 20 to ensure the stability of the transmission roller 344 when transmitting, and at the same time, the power generated by the transmission motor 332 will not be lost.

[0026] like Figure 1 , Figure 4 , Figure 6As shown, by firmly installing the fixing plate 321 on the support frame 20, a space for the extrusion plate 322 to move can be provided. By slidingly setting the extrusion plate 322 in the fixing plate 321, wherein the extrusion plate 322 is arranged at the output end of the gas pressure rod, the extrusion plate 322 can be adjusted in position within a certain range to adapt to PCB boards of different sizes and thicknesses. By also fixing a fixed protrusion 323 on the extrusion plate 322, the fixed protrusion 323 is used to fix the elastic member 324, and the limit plate 325 is connected through the elastic member 324, so that the limit plate 325 acts on the top of the PCB board, which is used to directly contact and squeeze the PCB board, thereby firmly fixing it in a specific position. Among them, the elastic member 324 provides the necessary pressure, and the limit plate 325 ensures that the pressure is evenly distributed, avoids excessive concentrated force on the PCB board, and protects the surface of the PCB board from damage. One side of the extrusion plate 322 is rotatably connected to a fixed wheel 327 through a fixed pin 326, which is used to place a fixed belt 328. Among them, the fixing belt 328 is slidably connected to the bottom of the limiting plate 325. Through the action of the limiting plate 325, the fixing belt 328 can act on the surface of the PCB board. When the PCB board is driven by the transmission component 33, it can drive the fixing belt 328 to rotate, so that the fixing belt 328 acts on other PCB boards, which can further provide transmission power.

[0027] In this embodiment, by placing the entire PCB template in the transmission plate 31, the transmission motor 332 is started to make the power act on the active transmission wheel 341 in the transmission assembly 34, and the transmission belt 342 arranged outside the active transmission wheel 341 and the driven transmission wheel 343 can transmit the power of the transmission motor 332, so as to drive the driven transmission wheel 343 and the transmission roller 344 fixedly connected thereto to rotate. Since the transmission roller 344 is fixedly connected to the transmission wheel 333, the transmission wheel 333 is driven to rotate, and the transmission belt 334 arranged outside the transmission wheel 333 is driven to rotate. Since the transmission belt 334 is arranged in the transmission groove 311 and contacts with the bottom of the PCB board, the PCB board is driven to move. Before the transmission motor 332 is started, the pneumatic rod on the extrusion plate 322 will drive the extrusion plate 322 to slide on the fixed plate 321, so that the bottom of the extrusion plate acts on the top of the PCB board, which can provide a limit and guide for the movement of the PCB board. Since the extrusion plate 322 is fixedly provided with a fixing protrusion 323, and the bottom of the fixing protrusion 323 is connected to the limiting plate 325 through the elastic member 324, the limiting plate 325 will be driven to act on the top of the PCB board for fixing. Among them, a fixing belt 328 is slidably provided at the bottom of the limiting plate 325, which can drive the fixing belt 328 to act on the top of the PCB board. When the PCB board is transported and moved, the fixing belt 328 can be driven to rotate through the PCB board. Since the fixing belt 328 is arranged on the outside of the fixing wheel 327, it can drive the fixing wheel 327 to rotate along the fixing pin 326, so that the fixing belt 328 can provide secondary power for the movement of the PCB board, and drive other PCB boards to move.

[0028] Preferably, by opening an adjustment slot on the bottom plate 10 and fixing an adjustment track 11 in the adjustment slot, the adjustment track 11 provides a sliding path for the adjustment plate 12, so that the adjustment plate 12 can adjust its position as needed, so that it can adapt to PCB boards of different sizes. By fixing the adjustment plate 12 at the output end of the pneumatic pressure rod 13 and driving it by air pressure, a stable power source can be provided to push the shearing knife 414 to adjust, which can reduce safety risks during operation.

[0029] Preferably, by setting the mounting rail 22 in the mounting groove 21, a stable guide can be provided for the movement of the shearing plate assembly 41 and the cutting plate assembly 42, so that the shearing plate assembly 41 and the cutting plate assembly 42 can be flexibly adjusted as needed to meet the processing requirements of plates of different sizes and types. At the same time, during production, the shearing plate assembly 41 and the cutting plate assembly 42 can work at the same time, one side performs large-scale shearing, and the other side performs fine cutting, which greatly improves production efficiency.

[0030] like Figure 1 , Figure 3 , Figure 8As shown, by fixing the drive motor 411 at the bottom of the support frame 20, the drive motor 411 is the main power source for the shearing assembly 41 to adjust. By fixing the drive plate 412 at the output end of the drive motor 411, the drive plate 412 can be driven to move smoothly along the mounting track 22, thereby driving the shearing knife 414 at the bottom of the drive plate 412 to move to the PCB board shearing position. It should be noted that the shearing assembly 41 adopts a double straight knife slitting design, and the shearing knife 414 is fixedly arranged at the output end of the shearing motor 413. Among them, the shearing motor 413 is fixedly arranged at the bottom of the drive plate 412 and above the adjustment plate 12. The shearing knife 414 is directly driven by the shearing motor 413 to perform a shearing action, so that the shearing knife 414 acts on the PCB board, which can ensure high precision and high efficiency during the shearing process.

[0031] like Figure 7 , Figure 8 As shown, by fixing the driving pressure rod 421 at the bottom of the support frame 20, it can be ensured that the driving pressure rod 421 can effectively generate power, and the power is smoothly transmitted to the sliding frame 422, thereby driving the sliding frame 422 to move smoothly along the mounting track 22, thereby ensuring that the cutting knife 425 can be accurately positioned to the position required for cutting. A lifting push rod 423 is fixedly arranged at the bottom of the sliding frame 422, which is used to drive the cutting knife 425 to complete the up and down cutting action through the guide plate 424, so that the finished PCB board can be effectively cut out from the template. The lifting push rod 423 and the cutting knife 425 can be connected through the guide plate 424, ensuring that the power of the lifting push rod 423 acts on the cutting knife 425. Among them, when the lifting push rod 423 is started, the cutting knife 425 can be controlled to perform cutting movement in the vertical direction through the guide plate 424, thereby achieving accurate cutting of the PCB board. Specifically, the guide rod 426 is fixed to the bottom of the sliding frame 422 and slidably connected to the guide plate 424, which can improve the stability and accuracy of the cutting knife 425 during the up and down movement of the cutting process. It can not only reduce the vibration of the equipment during the cutting process, but also ensure that the cutting knife 425 moves accurately along a straight path, thereby improving the cutting quality and efficiency.

[0032] like Figure 7 , Figure 8 , Fig. 9As shown, by fixing the collecting rack 51 on the adjusting plate 12, the adjusting plate 12 can be adjusted following the shearing plate assembly 41, ensuring that the collecting rack 51 can effectively support the PCB board. At the same time, it can ensure that the supporting area in the collecting rack 51 can effectively receive the PCB board transmitted from the transmission assembly 33. It should be noted that the supporting area on the collecting rack 51 is set in a slope shape, which can effectively transfer the sheared PCB board to the collecting card slot 511. By setting a collecting drive belt in the collecting card slot 511 and driving it through a collecting motor, the PCB board located in the collecting card slot 511 can be effectively transferred, and then enter the finished product track 521 and the waste track 522 for collection. Among them, the collecting card slot 511 can fix the PCB board to ensure that it remains stable during the cutting work. Specifically, by dividing the collecting track 52 into a finished product track 521 and a waste track 522, the effective separation of finished products and waste can be achieved. It helps to improve production efficiency and reduce the waste of resources caused by improper waste treatment.

[0033] In this embodiment, based on the above embodiment, when the PCB board is moved to the shearing area through the transmission of the transmission mechanism 30, the PCB board will be slidably connected with the collection rack 51 in the collection assembly 50, and enter the support area (i.e., the shearing area) in the collection rack 51. Through the support of the transmission plate 31 and the collection rack 51, the stability and safety during shearing can be ensured. When the infrared sensor on the drive plate 412 detects the shearing position, the shearing motor 413 will be driven to work simultaneously, so that it drives the shearing knife 414 to shear the PCB board. Among them, when the infrared sensor on the drive plate 412 receives the signal sent by the sensor on the transmission plate 31, the shearing knife 414 will be adjusted according to the shearing position, and the adjustment plate 12 and the drive plate 412 will be driven to move respectively by controlling the pneumatic pressure rod 13 and the drive motor 411, ensuring that the shearing knife 414 can be driven to accurately correspond to the shearing position. After the shearing task is completed, the PCB board will slide into the collection slot 511 in the collection frame 51, and the collection drive belt in the collection slot 511 will drive the PCB board to move to the cutting area. At this time, the infrared sensor on the guide plate 424 will detect the cutting position, and control the driving pressure rod 421 at the same time, so that it drives the sliding frame 422 to adjust and complete the precise alignment. Then, the cutting motor drives the cutting knife 425 to rotate, and the lifting push rod 423 drives the cutting knife 425 to move up and down to complete the cutting work of the PCB board, so that the complete PCB board falls into the finished product track 521, and then is transmitted to the collection box through the finished product track 521. At this time, the collection drive belt can drive the PCB template edge material to move to the waste track 522 to collect the waste in a centralized manner. Through the control of the CNC center, the safety of the operation can be ensured, and PCB boards of different sizes can be adapted. Among them, in the present invention, the cutters are all made of high-speed steel with precision grinding, which can be repeatedly ground and used, which can extend the service life of the equipment, reduce the frequency of changing the cutters, and improve work efficiency.

[0034] In this embodiment, the present invention further provides a method for using a shearing device, which is applied to the above-mentioned shearing device for PCB board manufacturing, and includes the following steps: Step 1: placing the whole PCB template with shearing on the transmission plate 31 in the transmission mechanism 30; Step 2: Start the pneumatic rod to drive the extrusion plate 322 to slide on the fixed plate 321, so that the extrusion plate 322 drives the limit plate 325 to move to the surface of the PCB board through the fixed protrusion 323 and the elastic member 324, and at the same time drives the fixed wheel 327 and the fixed belt 328 rotating on the fixed wheel 327 to move to the surface of the PCB board through the fixed pin 326, and the PCB board is squeezed and fixed by the fixed belt 328 and the limit plate 325. Then, by starting the transmission motor 332, the active transmission wheel 341 fixed at its output end is driven, and the driven transmission wheel 343 is driven by the transmission belt 342 transmitted outside the active transmission wheel 341. Since the driven transmission wheel 343 is fixedly connected to the transmission wheel 333 through the transmission roller 344, the transmission wheel 333 can be driven to rotate. The transmission belt 334 and the balance wheel 335 are driven to rotate by the transmission wheel 333. Since the transmission belt 334 is arranged in the transmission groove 311 opened in the transmission plate 31, and when the PCB template is squeezed and fixed, the bottom of the PCB template can generate friction on the transmission belt 334, thereby driving the PCB template to move.

[0035] Step 3: When the PCB template is transferred to the shearing area through the transmission mechanism 30, the PCB template is located above the transmission plate 31 and the collection rack 51. The infrared sensor provided on the transmission plate 31 cooperates with the infrared sensor on the driving plate 412 to control the transmission of the transmission motor 332 and control the opening and closing of the shearing motor 413, so as to drive the shearing knife 414 to shear the PCB board. When the shearing position changes, the sensor sends a signal to the control center, and then controls the driving motor 411 and the pneumatic pressure rod 13 to drive and adjust the driving plate 412 and the adjusting plate 12 respectively, so that the driving plate 412 and the adjusting plate 12 are driven to move the shearing knife 414 to the corresponding shearing position.

[0036] Step 4. When the PCB board is sheared, it is driven by the collection drive belt in the collection slot 511 in the collection rack 51 and moved to the cutting position. At this time, the cutting position is detected by the infrared sensor arranged on the guide plate 424 and transmitted to the driving pressure rod 421, so that it drives the sliding rack 422 and the cutting knife 425 to move to the cutting position, and then the cutting motor is started to drive the cutting knife 425 to work. The guide plate 424 and the cutting knife 425 at the bottom are driven by controlling the lifting push rod 423 to approach the cutting position of the PCB board along the guidance of the guide rod 426, thereby completing the cutting work.

[0037] Step 5: After the cutting knife 425 completes cutting of the PCB board, the finished PCB board will fall into the finished product track 521 at the bottom of the collection rack 51. The PCB board that meets the quality standard can be transferred to the collection box through the finished product track 521 to enter the next process or be directly packaged. At this time, the PCB template frame after shearing and cutting will be driven by the collection drive belt to drive the edge material to the waste track 522, and the template frame will be collected through the waste track 522, which is convenient for subsequent centralized processing.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
