Description

Technical Field

[0001] This utility model relates to the field of edge trimming machines, specifically to an anti-deviation edge trimming machine. Background Technology

[0002] PC sheet, short for polycarbonate sheet, is an engineering plastic sheet made of polycarbonate material. It is widely used in various fields, such as construction, automotive, electronics, and medical, due to its high strength, high transparency, impact resistance, and lightweight properties. During the production and processing of PC sheets, they need to be trimmed according to size requirements to obtain workpieces of specific sizes and shapes, such as quadrilaterals and circles. To prevent the PC sheet from shifting during the trimming process, trimming machines are equipped with limiting mechanisms to keep the PC sheet within limits, thereby ensuring the quality of the trimming.

[0003] Chinese patent CN218170595U discloses a PC board trimming machine, including a PC board trimming machine, a positioning plate, and a bracket. By setting the positioning plate, handle, guide plate, spring, and fixing plate, the positioning plate can limit the PC board being trimmed on the PC board trimming machine during use, preventing the PC board from deviating during trimming and improving the stability of the PC board during trimming.

[0004] However, the above-disclosed technical solutions have the following shortcomings: they can only cut and trim one side of the PC board. When multiple sides of the PC board need to be cut, the PC board needs to be readjusted and re-clamped. The repeated disassembly and assembly work is labor-intensive and inconvenient to use. Furthermore, the positional accuracy of the PC board cannot be guaranteed after it is fixed again, making it difficult to guarantee the cutting quality of multiple sides. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that when performing multi-sided edge cutting on PC boards, multiple disassemblies, adjustments, and re-clamping are required, which is inconvenient and makes it difficult to guarantee the cutting accuracy. This invention proposes an anti-deviation edge cutting machine.

[0006] The technical solution of this utility model: An anti-deviation edge trimming machine, including a worktable, an edge trimming support plate on the worktable, a PC board placed on the edge trimming support plate, a gantry frame on the worktable, an edge trimming mechanism on the inner wall of the top of the gantry frame, and further including:

[0007] A pressure plate is placed in the middle of the PC board, and multiple springs are installed on the pressure plate;

[0008] A limiting plate is set on top of multiple springs, and the limiting plate is provided with a transverse groove and a longitudinal hole;

[0009] The transverse plate, which passes through the transverse groove on the limiting plate, is provided with clearance holes on the gantry for the transverse plate to pass through. Under vertical projection, the transverse plate only intersects with the right longitudinal edge of the PC plate. The limiting plate is provided with a transverse moving mechanism that drives the transverse plate to move.

[0010] The longitudinal positioning rod consists of two U-shaped sections. The upper horizontal section of the two U-shaped sections is located above the worktable, and the lower horizontal section is slidably connected to the bottom of the worktable along the longitudinal direction. The upper horizontal section of one of the two U-shaped sections is inserted into the longitudinal hole on the limiting plate. The bottom of the worktable is equipped with a longitudinal moving mechanism that drives the longitudinal positioning rod to move.

[0011] Preferably, the cutting edge support plate and the worktable are vertically provided with multiple opposite through holes, and the cutting edge support plate and the worktable are connected by bolts and nuts.

[0012] Preferably, the edge-cutting support plate is an anisotropic rubber plate, and multiple anti-slip stripes are arranged parallel to each other on the bottom of the pressure plate.

[0013] Preferably, in order to improve the consistency of movement between the limiting plate and the pressure plate, multiple insertion rods are provided on the pressure plate, and multiple blind holes for insertion rods are provided at the bottom of the limiting plate.

[0014] Preferably, the top of the limiting plate is provided with a mounting groove, which is connected to the transverse groove. The transverse moving mechanism includes a motor disposed in the mounting groove, a gear disposed on the output shaft of the motor, and a rack disposed on the transverse plate, wherein the rack meshes with the gear.

[0015] Preferably, it also includes fixed plates at the left and right ends of the workbench, with one end of the horizontal plate in contact with one of the fixed plates and the other end of the horizontal plate suspended in the air.

[0023] Example 1

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model proposes an anti-deviation trimming machine, including a worktable 1. The bottom of the worktable 1 is supported by multiple support legs. A trimming support plate 5 is provided on the worktable 1. Specifically, multiple opposing through holes are vertically arranged on the trimming support plate 5 and the worktable 1. The trimming support plate 5 and the worktable 1 are connected by bolts 6 and nuts. In an optional embodiment, four through holes are provided, located at the four corners of the trimming support plate 5. The trimming support plate 5 is an anisotropic rubber plate. Multiple anti-slip stripes are arranged parallel to each other on the bottom of the pressure plate 9. The anisotropic rubber plate has high hardness in the vertical direction and is soft in the horizontal direction. The softness in the horizontal direction during cutting results in small cross-sectional deformation and can more effectively trim the edge. Good fit reduces stress concentration. While micro-scratches from cutting may damage intermolecular structures, van der Waals forces, covalent bonds, or hydrogen bonds quickly repair the fracture, restoring the macroscopic structure to its original state. A PC board 7 is placed on the cutting support plate 5, and a gantry frame 2 is installed on the worktable 1. A cutting mechanism 3 is installed on the inner top wall of the gantry frame 2. The cutting mechanism 3 includes a moving module, a vertical telescopic module, and a power structure that drives the cutting head to rotate for cutting. The cutting mechanism 3 can cut edges according to a pre-programmed path. It should be noted that the cutting mechanism 3 is existing technology; machine tools can already perform moving, telescopic, and rotating cutting functions, so it will not be described in detail here. It also includes:

[0025] The pressure plate 9 is pressed in the middle of the PC board 7. Multiple springs 10 are provided on the pressure plate 9. To facilitate lifting the pressure plate 9 and placing it into the PC board 7, a handle 12 is provided on the side of the pressure plate 9.

[0026] A limiting plate 8 is disposed on top of multiple springs 10. The limiting plate 8 is provided with a transverse groove and a longitudinal hole. In order to improve the consistency of movement between the limiting plate 8 and the pressure plate 9, multiple insertion rods 11 are provided on the pressure plate 9. The bottom of the limiting plate 8 is provided with multiple blind holes for insertion rods 11. In an optional embodiment, four springs 10 and four insertion rods 11 are provided. The four springs 10 are located at the four corners of the pressure plate 9, and the insertion rods 11 are located inside the springs 10.

[0027] The transverse plate 13 passes through the transverse groove on the limiting plate 8. The gantry 2 is provided with a clearance hole 4 for the transverse plate 13 to pass through. Under vertical projection, the transverse plate 13 only intersects with the right longitudinal edge of the PC plate 7. That is, the transverse plate 13 reserves the cutting edge space for the other three edges of the PC plate 7. The limiting plate 8 is provided with a transverse moving mechanism to drive the transverse plate 13 to move.

[0028] The longitudinal positioning rod 17 consists of two U-shaped rods. The upper horizontal section of the two U-shaped rods is located above the worktable 1, and the lower horizontal section is slidably connected to the bottom of the worktable 1 along the longitudinal direction. The upper horizontal section of one of the two U-shaped rods is inserted into the longitudinal hole on the limiting plate 8. That is, only one of the two U-shaped rods is located above the PC board, and the other U-shaped rod is left with a cut edge. The bottom of the worktable 1 is provided with a longitudinal moving mechanism that drives the longitudinal positioning rod 17 to move.

[0029] The system is connected to the trimming mechanism 3, the lateral movement mechanism, and the longitudinal movement mechanism.

[0030] Example 2

[0031] like Figure 2 and Figure 4 As shown, this utility model proposes an anti-deviation cutting machine. Compared with Embodiment 1, this embodiment details the structure of the lateral movement mechanism.

[0032] The top of the limiting plate 8 is provided with a mounting groove, which is connected to the transverse groove. The transverse moving mechanism includes a motor 15 installed in the mounting groove, a gear 16 installed on the output shaft of the motor 15, and a rack 14 installed on the transverse plate 13. The rack 14 meshes with the gear 16. The motor 15 is an encoder motor, which facilitates the control system to accurately control its rotation angle, thereby accurately controlling the moving distance of the rack 14 and the transverse plate 13.

[0033] Furthermore, fixed plates 22 are provided at both ends of the workbench 1. One end of the horizontal plate 13 is in contact with one of the fixed plates 22, and the other end of the horizontal plate 13 is suspended. In this embodiment, pressure sensors are provided on the opposite end faces of the two fixed plates 22 to detect whether the horizontal plate 13 is in place. The control system is connected to the pressure sensor signal transmission.

[0034] Example 3

[0035] like Figure 2 and Figure 3 As shown, this utility model proposes an anti-deviation cutting machine. Compared with Embodiment 1, this embodiment details the structure of the longitudinal moving mechanism.

[0036] The longitudinal moving mechanism includes a slide plate 18 that slides longitudinally along the bottom of the worktable 1, a support plate 19 that is disposed at the bottom of the slide plate 18, a mounting frame 21 that is disposed at the bottom of the worktable 1, and a telescopic device 20 that is longitudinally disposed on the mounting frame 21. The telescopic end of the telescopic device 20 is connected to the support plate 19. The telescopic device 20 is a cylinder, a hydraulic cylinder, or an electric push rod. The control system is connected to the telescopic device 20. Both ends of the slide plate 18 are respectively connected to the bottom of two U-shaped rods. In an optional embodiment, a slide rail is longitudinally disposed at the bottom of the worktable 1, and a slide groove that cooperates with the slide rail is disposed on the slide plate 18. The slide groove is a dovetail groove or a T-groove.

[0037] In summary, when using this utility model, hold the handle 12 and lift the pressure plate 9 upwards, then place the PC board 7 on the edge-cutting support plate 5, release the handle, and the pressure plate 9 presses down on the PC board 7. The pressure can be adjusted by different springs 10. The edge-cutting mechanism 3 first cuts the edges of the PC board 7 that have processing space according to the pre-set program. In this embodiment, a quadrilateral PC board 7 is used as an example. The edge-cutting mechanism 3 first cuts the lower edge and the left edge of the PC board 7. The edge-cutting mechanism 3 moves to the left end of the upper edge of the PC board 7 and stops. Then, the telescopic device 20 extends and inserts another U-shaped rod into the longitudinal hole. The previous U-shaped rod in the longitudinal hole is withdrawn. Then, the motor 15 works, causing the transverse plate 13 to move to the left until it abuts against the fixed plate 22 on the left. At this time, the upper edge and the right edge of the PC board 7 are freed up. The edge-cutting mechanism 3 can then continue to complete the edge-cutting of the other two edges. During the entire edge-cutting process, the pressure plate 9 and the limiting plate 8 always keep their positions fixed, which can provide a stable clamping force for the PC board 7 and prevent the PC board 7 from shifting during the multi-sided edge-cutting process, thus ensuring the processing quality. It also eliminates the need for operators to repeatedly disassemble and reassemble the PC board 7, making it more convenient to use. It should be noted that in this utility model, the control system and the control connection between the cutting mechanism, the motor 15 and the telescopic device 20 are all conventional electrical connection structures, and there is no improvement to the electrical connection structure. Therefore, the electrical connection structure of this part is not described in detail.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
