Improved three-way sensing structure for circuit board beveling machine

Abstract

This utility model relates to an improved three-directional sensing structure for a circuit board beveling machine. The three-directional sensing mechanism is mounted on an elevated horizontal rail above the machine platform and is driven by a servo motor to move along the rail. It includes a CCD camera and a laser height sensor located directly above the upper and lower clamping mechanisms of the beveling machine. This allows direct detection of the horizontal and vertical skew and height difference of the circuit board to be beveling. Based on the measured data, the relevant directional drive motors are activated for three-directional path compensation movement, enabling the beveling cutting mechanism to accurately cut the bevel of the circuit board. During the circuit board detection process, a certain height distance is maintained between the bottom of the three-directional sensing mechanism and the top of the beveling cutting mechanism, preventing mutual interference during their movement. This reduces the number of movement steps for both the three-directional sensing mechanism and the beveling cutting mechanism, effectively improving the overall efficiency of circuit board beveling.

Description

Technical Field

[0001] This utility model relates to the field of circuit board beveling machines, and in particular to an improved three-directional sensing structure for circuit board beveling machines. Background Technology

[0002] The circuit board beveling machine is a special machine for beveling the output terminals of circuit boards. It mainly uses a pneumatic suction cup assembly that can move left and right to pick up the circuit board and transport it to the platform for positioning. Then, the circuit board is fixed by a fixing and transmission mechanism and sent into the upper and lower clamping mechanism for clamping. Finally, the beveling cutting mechanism is used to bevele the output terminals of the circuit board.

[0003] Currently, circuit board beveling machines equipped with three-way sensing devices, such as the Taiwan utility model patent No. M551399, have a beveling cutting mechanism A mounted on a movable slide B. The movable slide B is equipped with a transverse drive motor B1 for transverse movement. The beveling cutting mechanism A has a tool longitudinal drive motor A1 and a tool vertical drive motor A2 to control its longitudinal and vertical movement. A three-way sensing device C is mounted on the horizontal rail D above the machine. It includes a CCD camera C1 and a laser height sensor C2 to detect the edge of the circuit board and measure its height difference. This drives the transverse drive motor B1, the tool longitudinal drive motor A1, and the tool vertical drive motor A2, allowing the beveling cutting mechanism A to make three-way micro-movement corrections based on the horizontal skew caused by clamping and the vertical height difference caused by warping deformation, thus accurately cutting the beveled edge of the circuit board. This type of circuit board beveling machine equipped with a three-way sensing device C can detect the horizontal and vertical deviations and height differences of the circuit board. However, during operation, the three-way sensing device C and the upper edge of the beveling cutting mechanism A will interfere with each other during movement. Therefore, before the circuit board is clamped by the upper and lower clamping mechanisms and before the beveling is cut, the three-way sensing device C is in a standby position away from the beveling cutting mechanism (A). At this time, the tool longitudinal drive motor A1 starts, causing the beveling cutting mechanism A to retract. Then, the three-way sensing device C moves to the side closer to the beveling cutting mechanism A, gradually detects the circuit board, and then returns to the standby position to avoid collision between the two. Figure 1 and Figure 2 As shown. However, this configuration structure requires the three-way sensing device C and the bevel cutting mechanism A to take additional steps to avoid collisions before cutting the bevel of the circuit board, which will inevitably reduce the efficiency of bevel cutting.

[0004] Therefore, traditional circuit board beveling machines equipped with three-way sensing devices still have shortcomings in operation and use, and need to be improved. Utility Model Content

[0005] The main objective of this invention is to provide an improved three-way sensing structure for a circuit board beveling machine. By installing a three-way sensing mechanism equipped with a CCD camera and a laser height sensor on the top of an elevated horizontal rail above the machine, a certain height distance is reserved between the three-way sensing mechanism and the beveling machine cutting mechanism, allowing direct detection of the circuit board without mutual interference. This structure reduces the number of movement steps of the three-way sensing mechanism and the beveling cutting mechanism, thereby improving the beveling cutting efficiency of the circuit board.

[0006] To achieve at least some of the above objectives, this utility model provides an improved three-directional sensing structure for a circuit board beveling machine. The beveling machine includes a main body, a fixing and transmission mechanism, an upper and lower clamping mechanism, a beveling cutting mechanism, and a three-directional sensing mechanism. The fixing and transmission mechanism fixes one side of a circuit board placed on the main body platform. The edge of the circuit board is then fed into the upper and lower clamping mechanism for clamping. The beveling cutting mechanism then performs beveling cutting on the output terminals of the circuit board. A movable slide with a transverse transmission motor is installed at the bottom rear of the main body. The beveling cutting mechanism is mounted on the movable slide and can move laterally. A longitudinal transmission motor and a vertical transmission motor for the tool are also provided on the slide to control the longitudinal and vertical movement of the beveling cutting mechanism. The three-directional sensing mechanism includes a fixed base and a three-directional sensing device. The fixed base has a transmission screw and a servo motor mounted on it, which is installed above the main body of the beveling machine. The top of the horizontal rail is raised, and the three-way sensing device is mounted on the moving screw of the fixed base and can move left and right via the servo motor. It includes a CCD camera and a laser height sensor located directly above the upper and lower clamping mechanism, which can detect the horizontal deviation and vertical height difference of the circuit board to be cut. Based on the measured data, the horizontal transmission motor, the longitudinal transmission motor of the tool, and the upper and lower transmission motor of the tool are simultaneously activated to perform three-way path compensation movement, so that the bevel cutting mechanism can accurately cut the bevel of the circuit board. The three-way sensing improved structure of the circuit board bevel cutting machine composed of the above components has a certain height distance between its bottom end and the top end of the bevel cutting mechanism during the detection of the circuit board. Therefore, the two will not interfere with each other when moving, which can reduce the movement steps of the three-way sensing device and the bevel cutting mechanism and effectively improve the overall efficiency of bevel cutting of the circuit board.

[0007] In some embodiments, before the circuit board is clamped by the upper and lower clamping mechanisms but before the bevel is cut, the three-way sensing device is located above the edge of the circuit board output terminal, and can directly collect single-point data or move between two points to detect the circuit board, depending on the size and type of the circuit board.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. Please refer to... Figure 3This utility model relates to an improved three-directional sensing structure for a beveling machine for circuit boards. The beveling machine mainly consists of a beveling machine body 1, a fixing and transmission mechanism 2, an upper and lower clamping mechanism 3, a beveling cutting mechanism 4, and a three-directional sensing mechanism 5. Its front section uses a left-right movable pneumatic suction cup assembly (not shown in the icon) to pick up the circuit board 6 and transport it to the beveling machine platform for positioning. Then, the fixing and transmission mechanism 2 fixes one side of the circuit board 6, and the edge to be beveled is fed into the upper and lower clamping mechanism 3 for clamping. Finally, the beveling cutting mechanism 4 performs beveling cutting on the output terminals of the circuit board.

[0022] The aforementioned beveling cutting mechanism 4 is mounted on a movable slide 7 at the bottom rear side of the beveling machine body 1. A transverse transmission motor 71 is mounted on the movable slide 7, allowing it to move laterally. The beveling cutting mechanism 4 is equipped with a tool longitudinal transmission motor 41 and a tool vertical transmission motor 42 to control the longitudinal and vertical movement of the beveling cutting mechanism 4.

[0023] The aforementioned three-way sensing mechanism 5 includes a fixed base 51 and a three-way sensing device 52. The fixed base 51 is equipped with a transmission screw 511 and a servo motor 512, which is mounted on the top of the heightened horizontal rail 11 above the beveling machine body 1. The three-way sensing device 52 is mounted on the transmission screw 511 of the fixed base 51 and can move left and right via the servo motor 512. It includes a CCD camera 521 located directly above the upper and lower clamping mechanism 3 and a laser height sensor 522, which can detect the edge and height of the circuit board to be beveled. Figure 4 and Figure 5 As shown.

[0024] Before the bevel is cut, the circuit board 6 is fed into the upper and lower clamping mechanism 3. The three-way sensing mechanism 5 is located above the edge of the output terminal of the circuit board 6. It can directly collect single-point or two-point data to detect the horizontal deviation and vertical height difference of the circuit board 6 according to its size and type. Based on the measured data, the transverse transmission motor 71, the tool longitudinal transmission motor 41 and the tool upper and lower transmission motor 42 are activated to perform three-way path compensation movement. This allows the bevel cutting mechanism 4 to correct the horizontal deviation caused by clamping and the vertical height difference caused by warping deformation of the circuit board 6, so that the bevel can be accurately cut.

[0025] During the detection of the circuit board, the three-way sensing device 52 maintains a certain height distance between its bottom and the top of the bevel cutting mechanism 4, preventing mutual interference during their movement. This reduces the number of movement steps for both the three-way sensing device 52 and the bevel cutting mechanism 4, effectively improving the overall efficiency of bevel cutting of the circuit board. Figure 6 and Figure 7 As shown.

[0026] In summary, the improved three-way sensing structure of the circuit board beveling machine of this utility model solves the problem of mutual interference between the three-way sensing device and the beveling cutting mechanism during the operation of the traditional circuit board beveling machine. By installing the three-way sensing device equipped with a CCD camera and a laser height sensor on the top of the heightened horizontal rail above the machine, the three-way sensing device will not interfere with the beveling cutting mechanism when detecting the edge and height difference of the circuit board, thereby improving the overall beveling cutting efficiency of the circuit board.

[0027] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model, or reasonable combinations of features and solutions from various embodiments, are all within the protection scope of the present utility model.
