Description

Technical Field

[0001] This utility model relates to the field of computer processing, specifically to an automatic positioning and locking device for computer hardware processing. Background Technology

[0002] As one of the most commonly used electronic devices in people's lives today, computers mainly consist of CPU, RAM, hard disk, graphics card, and motherboard. During the production process, motherboards are usually mass-produced and then cut into sections using appropriate cutting equipment. In order to prevent the workpiece from becoming loose during the cutting process, a positioning automatic locking device for computer hardware processing is needed to position the PCB motherboard.

[0003] Existing automatic positioning and locking devices for computer hardware processing include a cutting table for placing PCB motherboards, a cutting machine that cuts the PCB motherboards through the cutting table, and a chain conveyor that controls the unidirectional movement of the cutting machine. The cutting table has a cutting groove inside that restricts the movement direction of the cutting machine. The cutting machine is located below the cutting table. The chain conveyor can be referenced to the chain-type moving spindle that controls the Z-axis movement of a three-axis CNC machine tool. To facilitate the calibration of the cutting lines of the PCB motherboards and the cutting of the saw blade, a laser positioning crosshair is installed above the cutting groove, facing the saw blade edge. To facilitate the calibration of PCB motherboards in different positions, a mounting bracket is installed above the laser positioning crosshair. The top surface of the laser positioning crosshair has a lamp protrusion that passes through the mounting bracket, allowing the laser positioning crosshair to slide back and forth along the top surface of the mounting bracket.

[0004] During the cutting process, the accuracy of the PCB motherboard can be guaranteed because the cutting position is pre-calibrated by the laser positioning cross light. However, some PCB motherboards have a large area, and when cutting the center position of the PCB motherboard, the PCB motherboard often warps due to the rotation of the saw blade. Once warping occurs during the cutting process, it is easy to damage the edge of the PCB motherboard or even damage the internal solder joints of the circuit board. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing automatic positioning and locking devices for computer hardware processing are prone to warping at the cutting center of large PCB motherboards.

[0006] To solve the above technical problems, the technical solution provided by this utility model is: an automatic positioning and locking device for computer hardware processing, including a cutting table for placing a PCB motherboard and a cutting machine for cutting the PCB motherboard. The cutting table is provided with a cutting groove through which the saw blade of the cutting machine passes, and the cutting machine is controlled by a chain conveyor to move back and forth along the cutting groove.

[0007] Above the cutting groove is a laser positioning cross light for marking the cutting line of the PCB motherboard. Above the cutting table is a fixing frame for connecting the laser positioning cross light, and the laser positioning cross light is slidably connected to the bottom surface of the fixing frame through a concave-convex slot structure.

[0008] The left and right sides of the fixed frame are equipped with several electric telescopic rods perpendicular to the PCB motherboard, and the base of the electric telescopic rod is slidably connected to the left and right sides of the fixed frame through a concave-convex groove structure. A remote control for controlling the electric telescopic rod, chain conveyor and cutting machine is provided on one side of the fixed frame.

[0009] As an improvement, the input end of the cutting table is provided with several sliding blocks for fixing the PCB motherboard, and a convex block passing through the cutting table is provided below the sliding blocks.

[0010] As an improvement, each of the sliding blocks is connected by a connecting strip, and the connecting strip is connected to the rear side wall of the sliding block by a bolt structure. The connecting strip is provided with pulleys on both sides, and the cutting table is provided with grooves on both sides to restrict the movement direction of the pulleys.

[0011] As an improvement, the PCB motherboard is provided with a pre-cut groove on the top for easy laser positioning of the crosshair and cutting position.

[0012] As an improvement, the top of the output shaft of the electric telescopic rod is provided with a silicone gasket to prevent damage to the PCB motherboard.

[0013] As an improvement, the electric telescopic rod has a pressure sensor inside that detects the downward pressure of the output shaft.

[0014] The advantages of this invention compared to the prior art are as follows: This device has electric telescopic rods installed on both sides of the fixed frame, and the electric telescopic rods are connected to both sides of the fixed frame through a concave-convex groove structure. That is, the left and right sides of the fixed frame are welded with side convex blocks, and the side convex blocks pass through the base side wall of the electric telescopic rod, so that the groove of the electric telescopic rod can slide along the side convex blocks. In this way, the output shaft of the electric telescopic rod can press on both ends of the cut surface of the PCB motherboard, while ensuring that the output shaft of the electric telescopic rod will not damage the solder joints of the PCB motherboard, thereby ensuring the safety of the PCB motherboard.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] As per the instruction manual Figure 1 , 2 As shown in Figures 3, 4, and 5, the current PCB motherboard 1 cutting device includes a cutting table 2 for placing the PCB motherboard 1 and a cutting machine 3 for cutting the PCB motherboard 1. The cutting machine 3 is controlled by a chain conveyor 4 to move back and forth along the cutting groove 31. In order to facilitate the control of the cutting direction of the saw blade of the cutting machine 3, the cutting table 2 is provided with a cutting groove 31 that passes through the saw blade of the cutting machine 3. The chain conveyor 4 can refer to the movement mode of the chain-type moving spindle that controls the Z-axis movement of a three-axis CNC machine tool, and can control the saw blade of the cutting machine 3 to move back and forth along the cutting groove 31.

[0024] To ensure the accuracy of the edge of the PCB motherboard 1 after cutting, a laser positioning cross light 5 for marking the cutting line of the PCB motherboard 1 is provided above the cutting groove 31, and a pre-cutting groove 15 is provided above the PCB motherboard 1 to facilitate the positioning of the cutting position by the laser positioning cross light 5. To facilitate the detection of cutting points at different positions, a fixing frame 6 for connecting the laser positioning cross light 5 is provided above the cutting table 2, and the laser positioning cross light 5 is slidably connected to the bottom surface of the fixing frame 6 through a concave-convex slot structure. That is, the laser positioning cross light 5 has a lamp protrusion block passing through the fixing frame above it, so that the laser positioning cross light 5 can slide back and forth along the top surface of the fixing frame.

[0025] Similarly, to ensure that the PCB motherboard 1 does not bulge at the center during cutting, the left and right sides of the fixing frame 6 are equipped with electric telescopic rods 7 perpendicular to the PCB motherboard 1. The base of the electric telescopic rod 7 is slidably connected to the left and right sides of the fixing frame 6 through a concave-convex groove structure. That is, the left and right sides of the fixing frame 6 are welded with side convex blocks, and the side convex blocks pass through the side wall of the base of the electric telescopic rod 7, so that the bottom groove of the electric telescopic rod 7 can slide along the side convex blocks. This allows the output shaft of the electric telescopic rod 7 to press on both ends of the cut surface of the PCB motherboard 1 while ensuring that the output shaft of the electric telescopic rod 7 will not damage the solder joints of the PCB motherboard 1. In order to prevent the output shaft of the electric telescopic rod 7 from damaging the PCB motherboard 1, a silicone gasket 71 is provided at the top of the output shaft of the electric telescopic rod 7 to prevent damage to the PCB motherboard 1. The electric telescopic rod 7 also has a pressure sensor inside to detect the downward pressure of the output shaft. With the silicone gasket 71 as a buffer contact, it can be ensured that the electric telescopic rod 7 will not have excessive pressure and break through the PCB motherboard 1.

[0026] To effectively control the input end of the PCB motherboard 1, several sliding blocks 11 for fixing the PCB motherboard 1 are provided on one side of the input end of the cutting table 2. A convex block 111 passing through the cutting table 2 is provided below the sliding block 11. The movement direction of the sliding block 11 is restricted by the convex block 111. The sliding block 11 is a common CNC machine tool fixed pressure plate, which consists of a single open shell, a screw passing through the top surface of the shell, and a pressure plate located at the open end of the single open shell. The screw passes through the top surface of the pressure plate, and the pressure plate is tightly attached to the inner wall of the shell. In order to ensure the unidirectional movement of the sliding block 11, the convex block 111 is welded to the bottom surface of the shell, so that it slides along the convex block 111 inside the cutting table 2. The stability of the sliding block 11 can be ensured by controlling the tightness of the top screw while pressing the PCB motherboard 1.

[0027] To facilitate the uniform movement of the sliding blocks 11, each of the sliding blocks 11 is connected by a connecting strip 12, and the connecting strip 12 is connected to the bottom side wall of the open end of the housing of the sliding block 11 by a bolt structure. The connecting strip 12 is provided with pulleys 13 on both sides, and the cutting table 2 is provided with grooves 14 on both sides to restrict the movement direction of the pulleys 13. The sliding of multiple sliding blocks 11 is controlled by moving the connecting strip 12, and the force required for sliding can be reduced by the sliding of the pulleys 13 and the grooves 14.

[0028] The electric telescopic rod 7 on one side of the fixed frame 6, the chain conveyor 4 on the bottom of the cutting table 2, and the cutting machine 3 are all controlled by the remote control 8.

[0029] In a specific implementation of this utility model, the PCB motherboard 1 is placed above the cutting table 2, and the pre-cut groove 15 is calibrated by the laser positioning cross light 5. Then, the electric telescopic rod 7 is activated to press it onto the blank area of ​​the PCB motherboard 1. Next, the connecting bar 12 is moved to fix the sliding pressure block 11 above the PCB motherboard 1, thereby fixing its bottom surface. Finally, the cutting machine 3 and the chain conveyor 4 are started to cut the PCB motherboard 1. The feed speed of the chain conveyor 4 and the rotation speed of the cutting machine 3 can be adjusted by the remote control 8.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
