They are widely used in public and civil buildings for lighting and rain shelters, passageway roofs, elevated road sound barriers, shopping mall roofs, and plant greenhouses.

[0003] In response, Chinese patent application number CN218170595U discloses a PC board trimming machine, including a PC board trimming machine, a positioning plate, and a bracket. The PC board trimming machine is slidably connected to the positioning plate. A roller is rotatably connected to the lower inner side of the positioning plate, and the roller is in contact with the PC board trimming machine. A handle is fixedly connected to the center of the front end of the positioning plate. Guide plates are slidably connected to both the left and right sides of the outer side of the positioning plate, and the guide plates are fixedly connected to the PC board trimming machine. A spring is fixedly connected to the front inner side of the guide plate, and the spring is fixedly connected to the positioning plate. Fixed plates are slidably connected to the upper sides of both the left and right sides of the positioning plate. Through the positioning plate, handle, guide plate, spring, and fixed plate, the positioning plate can limit the PC board being trimmed on the PC board trimming machine during use, preventing the PC board from shifting during trimming and improving the stability of the PC board during trimming.

[0004] In the process of developing this application, the inventors discovered the following problems in the technology:

[0005] 1. Although the PC board production edge cutting machine mentioned in the above application can limit the PC board being cut on the PC board edge cutting machine by the positioning plate during use, and prevent the PC board from deviating during edge cutting and improve the stability of the PC board during edge cutting, it lacks an effective debris collection and treatment mechanism, which makes the working environment susceptible to debris pollution, increases cleaning costs, and the debris may also pose a potential safety hazard to the equipment and operators. Utility Model Content

[0006] To address the aforementioned issues, this application provides a cutting machine for PC board production with positioning functionality.

[0007] The edge-cutting machine for PC board production with positioning function provided in this application adopts the following technical solution:

[0008] A PC board production edge trimming machine with positioning function includes a table, the bottom of which is rectangular and fixedly equipped with four table legs, and the top of which is provided with a sliding groove, and a retainer that restricts the position of the PC board is slidably arranged inside the sliding groove.

[0009] An adjustment mechanism is installed on the table and is used to adjust the position of the support frame according to the size of the cut edge of the PC board.

[0010] A collection component is set on a table and used to collect debris generated during the cutting process of PC boards.

[0011] By adopting the above technical solution, the edge trimming machine achieves efficient and flexible processing operation. The support frame, which is slidably set in the groove opened on the top of the table, can be precisely adjusted according to the size of the PC board edge to ensure the stable positioning of the PC board during processing, in conjunction with the adjustment mechanism. At the same time, the collection component set on the table effectively collects the debris generated during the edge trimming process, keeping the work area clean and safe, and improving the overall accuracy, efficiency and comfort of the PC board edge trimming process.

[0012] As a further step of this solution, the adjustment mechanism includes two fixed seats 1 symmetrically fixedly disposed at the bottom of the table at the slide groove. The same lead screw is rotatably disposed on the side of the two fixed seats 1 that are close to each other. The lead screw is threadedly connected to the bottom of the support frame. A driven bevel tooth is fixedly disposed at one end of the lead screw. Two fixed seats 2 are symmetrically fixedly disposed at the bottom of the table. The same rotating rod is rotatably disposed on the side of the two fixed seats 2 that are close to each other. A driving bevel tooth is fixedly disposed at the end of the rotating rod that is close to the driven bevel tooth. The driven bevel tooth meshes with the driving bevel tooth. A handwheel is fixedly disposed at the other end of the rotating rod.

[0013] By adopting the above technical solution, the design of the adjustment mechanism makes the position adjustment of the support frame simple and precise. By turning the handwheel, the rotating rod can be driven to rotate, which in turn drives the active bevel gear and the driven bevel gear on it to mesh and transmit power, causing the lead screw to rotate. Since the lead screw is threadedly connected to the bottom of the support frame, the rotation of the lead screw will be converted into the linear movement of the support frame along the slide groove, thereby realizing the precise adjustment of the support frame position. The symmetrical arrangement of the two fixed seats one and two, as well as the stable installation of the lead screw and the rotating rod, ensure the stability and reliability of the adjustment process, effectively improving the accuracy and efficiency of PC board edge cutting processing.

[0014] As a further step of this solution, the collection component includes a collection box fixedly installed on the top of the table, a fan fixedly installed on one side of the collection box, the air outlet of the fan being connected to the collection box, a suction pipe fixedly connected to the other side of the collection box, a cover box fixedly installed on the rear side of the support frame, the other end of the suction pipe being connected to the cover box, and a plurality of evenly distributed through holes opened on the front side of the support frame, all of which are connected to the cover box;

[0015] By adopting the above technical solution, the design of the collection component effectively solves the problem of debris collection during the PC board edge cutting process. A fan is used to suck air and debris from the cover box into the collection box through a suction pipe. The cover box is fixedly connected to the rear side of the support frame and is connected to the processing area through multiple through holes on the front side of the support frame, ensuring that the debris can be fully sucked in. This design not only improves the efficiency of debris collection, but also keeps the work area clean, reduces the impact of debris on processing accuracy and machine operation, reduces the health risks to operators, and improves the comfort and safety of the overall working environment.

[0016] As a further step of this solution, a pointer is fixedly installed on one side of the support frame, and a scale is provided on the top of the table near the pointer;

[0017] By adopting the above technical solution, the pointer fixed on one side of the support frame is combined with the scale near the top of the table, providing operators with an intuitive and accurate data reference. This design allows operators to quickly and accurately judge and adjust the specific position of the support frame when adjusting its position, thereby ensuring the precise positioning of the PC board during the processing. This not only improves the accuracy and efficiency of processing, but also reduces the risk of errors caused by improper position adjustment, providing a strong guarantee for the high-quality production of PC boards.

[0018] As a further step of this solution, the top of the collection box can be detached from the seal and inserted with a filter element frame, and a filter element can be detached from one side of the filter element frame;

[0019] By adopting the above technical solution, the top of the collection box has a detachable and sealed filter element frame, and the side has a detachable filter element. This provides an additional filtration and purification step for collecting debris generated during the PC board edge cutting process. This design allows the filter element to effectively block and adsorb tiny debris and impurities in the air drawn into the collection box by the fan, further improving the debris collection effect and the cleanliness of the air in the collection box. At the same time, the detachable design of the filter element frame and the filter element not only facilitates the replacement and maintenance of the filter element, but also ensures the continuity and stability of the filtration effect, providing strong support for the long-term and high-efficiency operation of the edge cutting machine.

[0020] As a further step of this solution, a motor is fixedly installed at the bottom of the table, a cutting blade is fixedly installed at one end of the motor output shaft, and a through groove is opened at the top of the table, with the cutting blade located in the through groove;

[0021] By adopting the above technical solution, the motor fixed at the bottom of the table and the cutting blade on its driven output shaft provide a direct and efficient power source for the edge cutting of PC boards. The motor drives the cutting blade to rotate at high speed in the through slot opened at the top of the table, which can accurately and quickly cut the PC boards placed on the table. This design not only improves the efficiency and accuracy of edge cutting, but also makes the entire edge cutting process more automated and intelligent, reduces the labor intensity of operators, and improves the overall production efficiency and product quality of the production line.

[0022] As a further improvement of this solution, each of the four table legs is threaded with a screw rod at its bottom, a rectangular adjusting block is fixedly installed at the bottom of each of the four screw rods, a support pad is rotatably installed at the bottom of each of the four rectangular adjusting blocks, a locking nut is threaded to the outside of each of the four screw rods, and an anti-slip pad is fixedly installed at the bottom of each of the four support pads.

[0023] By adopting the above technical solution, the combination design of the screw, rectangular adjustment block, support pad, and anti-slip pad at the bottom of the four table legs provides the edge trimming machine with flexible and stable support adjustment function. The operator can adjust the height of the rectangular adjustment block and support pad by rotating the screw, thereby achieving precise adjustment of the overall height of the edge trimming machine to adapt to different working environments and processing needs. At the same time, the rotating design of the support pad allows the edge trimming machine to maintain horizontal stability on uneven ground, while the anti-slip pad effectively prevents the machine from sliding and shifting during operation, ensuring the stability and safety of the processing process. In addition, the threaded connection of the locking nut ensures that the adjusted height can be firmly locked, avoiding adjustment failure caused by machine vibration or external factors.

[0024] As a further step of this solution, a metal enclosure is fixedly installed between each pair of adjacent table legs.

[0025] By adopting the above technical solution, the metal enclosure fixed between each pair of adjacent table legs provides an additional safety barrier for the edge cutting machine. This design not only effectively prevents debris and sparks generated during the edge cutting process from splashing onto the operator or the surrounding environment, ensuring the safety of the processing, but also reduces noise transmission and improves the overall comfort of the working environment. At the same time, the metal enclosure has good durability and impact resistance, and can maintain its structural integrity and functional stability for a long time, providing a strong guarantee for the long-term and efficient operation of the edge cutting machine.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This utility model, by setting an adjustment mechanism, realizes precise positioning and rapid adjustment of PC board during the edge cutting process, which not only improves the edge cutting accuracy and production efficiency, but also enhances the practicality and flexibility of the edge cutting machine, helps to reduce the difficulty of operation, and improves the automation level of the production line;

[0028] 2. This utility model, by incorporating a collection component, effectively collects and processes debris generated during the cutting of PC boards, improving the working environment, reducing cleaning costs, and effectively preventing potential hazards to equipment and operators from debris.

A retaining frame 6 that limits the position of the PC board is slidably installed inside the sliding groove 5.

[0037] An adjustment mechanism is provided on the table 1 and is used to adjust the position of the support 6 according to the size of the cut edge of the PC board.

[0038] A collection component is set on table 1 and is used to collect debris generated during the cutting process of PC board.

[0039] The above technical solution achieves efficient and flexible processing operation of the edge trimming machine. The support frame 6, which is slidably set in the slide groove 5 on the top of the table 1, can be precisely adjusted according to the size of the PC board edge trimming mechanism to ensure the stable positioning of the PC board during processing. At the same time, the collection component set on the table 1 effectively collects the debris generated during the edge trimming process, keeping the work area clean and safe, and improving the overall accuracy, efficiency and comfort of the PC board edge trimming process.

A handwheel 13 is fixedly arranged at the other end of the rotating rod 11.

[0041] The above technical solution achieves the following: the design of the adjustment mechanism makes the position adjustment of the support frame 6 simple and precise. By rotating the handwheel 13, the rotating rod 11 can be driven to rotate, which in turn drives the active bevel gear 12 and the driven bevel gear 9 to mesh and transmit power, causing the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the bottom of the support frame 6, the rotation of the lead screw 8 will be converted into the linear movement of the support frame 6 along the slide groove 5, thereby achieving precise adjustment of the position of the support frame 6. The symmetrical arrangement of the two fixed seats 1 7 and fixed seat 2 10, as well as the stable installation of the lead screw 8 and the rotating rod 11, ensure the stability and reliability of the adjustment process, effectively improving the accuracy and efficiency of PC board edge cutting.

[0043] The above technical solution effectively solves the problem of debris collection during the PC board trimming process by using a fan 18 to draw air and debris from the cover box 15 into the collection box 16 through a suction pipe 17. The cover box 15 is fixedly connected to the rear side of the support frame 6 and is connected to the processing area through multiple through holes 14 on the front side of the support frame 6, ensuring that the debris can be fully sucked in. This design not only improves the efficiency of debris collection but also keeps the work area clean, reduces the impact of debris on processing accuracy and machine operation, reduces the health risks to operators, and improves the comfort and safety of the overall working environment.

This provides an additional filtration and purification step for collecting debris generated during the PC board edge cutting process. This design allows the filter element 1602 to effectively block and adsorb tiny debris and impurities in the air sucked into the collection box 16 by the fan 18, further improving the debris collection effect and the cleanliness of the air in the collection box 16. At the same time, the detachable design of the filter element frame 1601 and the filter element 1602 not only facilitates the replacement and maintenance of the filter element 1602, but also ensures the continuity and stability of the filtration effect, providing strong support for the long-term and high-efficiency operation of the edge cutting machine.

[0050] Reference Figure 2 The bottom of each of the four table legs 2 is threaded with a screw 201, and a rectangular adjusting block 202 is fixedly installed at the bottom of each of the four screws 201. A support pad 203 is rotatably installed at the bottom of each of the four rectangular adjusting blocks 202. A locking nut 205 is threadedly connected to the outside of each of the four screws 201.

The operator can adjust the height of the rectangular adjustment block 202 and support pad 203 by rotating the screw 201, thereby achieving precise adjustment of the overall height of the edge trimming machine to adapt to different working environments and processing needs. At the same time, the rotation design of the support pad 203 enables the edge trimming machine to maintain horizontal stability on uneven ground, while the anti-slip pad 204 effectively prevents the machine from sliding and shifting during operation, ensuring the stability and safety of the processing process. In addition, the threaded connection of the locking nut 205 ensures that the adjusted height can be firmly locked, avoiding adjustment failure caused by machine vibration or external factors.

[0052] Reference Figure 1 and Figure 2 Each pair of adjacent table legs 2 is fixedly equipped with a guardrail 19, which is made of metal.

[0053] The above technical solution achieves the following: the metal enclosure 19 fixed between each pair of adjacent table legs 2 provides an additional safety barrier for the edge cutting machine. This design not only effectively prevents debris and sparks generated during the edge cutting process from splashing onto the operator or the surrounding environment, ensuring the safety of the processing, but also reduces noise transmission and improves the overall comfort of the working environment. At the same time, the metal enclosure 19 has good durability and impact resistance, and can maintain its structural integrity and functional stability for a long time, providing a strong guarantee for the long-term and efficient operation of the edge cutting machine.

[0054] However, as is well known to those skilled in the art, motor 3 and fan 18 are general standard parts or components known to those skilled in the art, and their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0055] The implementation principle of the PC board edge trimming machine with positioning function in this application embodiment is as follows: When the machine is unstable due to uneven ground at the beginning of use, rotate the rectangular adjustment block 202 at the corresponding position. While the rectangular adjustment block 202 rotates, it drives the screw 201 to turn out from the bottom of the table leg 2. While the screw 201 turns out, it drives the support pad 203 and its bottom protective pad 204 to move closer to the ground until the bottom protective pad 204 of the support pad 203 abuts against the ground. Then, follow the above operation to rotate the rectangular adjustment blocks 202 on the other table legs 2 in sequence, so that the machine as a whole reaches a level and stable state. Then, rotate the locking nut 205 so that the locking nut 205 abuts against the bottom of the table leg 2, thereby locking the position of the screw 201, thereby preventing the uneven ground from causing vibration during machine operation and affecting the edge trimming of the PC board. Then, connect the power supply to the machine.

[0056] When it is necessary to cut PC boards of different sizes or specifications, firstly, the rotating handwheel 13 drives the rotating rod 11 to rotate. The rotating rod 11 drives the active bevel gear 12 to rotate. The active bevel gear 12 drives the driven bevel gear 9 that meshes with it to rotate. The driven bevel gear 9 drives the lead screw 8 to rotate synchronously. The rotation of the lead screw 8 drives the abutment 6 to slide in the slide groove 5, thereby realizing the precise adjustment of the position of the PC board. While the abutment 6 is moving, observe the scale 602 pointed to by the pointer 601. When the pointer 601 points to the specified scale 602, stop the rotation of the handwheel 13.

[0057] At this time, motor 3 is started, and one end of the output shaft of motor 3 drives the cutting blade 4 to rotate at high speed. At the same time, fan 18 is started, and then the PC board is cut. During the cutting process, fan 18 will suck the collection box 16. At the same time, the suction pipe 17 is connected to the collection box 16, so that the suction of fan 18 also acts on the suction pipe 17. The suction pipe 17 generates suction inside the cover box 15, and then sucks the debris generated during the cutting process into the cover box 15 through the through hole 14. Then, it enters the collection box 16 through the suction pipe 17. The debris sucked into the collection box 16 will be filtered and blocked by the filter element 1602 to prevent the debris from entering the fan 18.

[0058] This application pertains to the field of edge trimming machines for PC board production with positioning function, but can also be applied to other fields within this application.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
