[0046] Embodiment 1

[0047] With reference to Figures 1 to 5 The embodiment provides a cutting knife assembly of a cutting bed, comprising:

[0048] a main housing;

[0049] a motor supporting block 8 arranged on the main housing, the motor supporting block 8 having a through channel from top to bottom;

[0050] a cutting knife supporting block 10 arranged below the motor supporting block 8;

[0051] a motor 9 arranged on the motor supporting block 8, a rotor of the motor 9 passing through the through channel and being connected with the cutting knife supporting block 10, and the motor 9 being capable of driving the cutting knife supporting block 10 to rotate;

[0052] a rotating mechanism arranged on a side surface of the cutting knife supporting block 10;

[0053] two types of knives arranged on the rotating mechanism at a preset included angle, and the rotating mechanism being capable of driving the two types of knives to rotate at a predetermined angle;

[0054] A control unit is configured to control the rotation of the rotating mechanism.

[0055] Specifically, in the embodiment, the main housing includes an upper housing 1 located at the top and a back plate 2 located below the upper housing, and a motor supporting block 8 is fixed to one side of the back plate 2. A motor 9 is arranged above the motor supporting block 8, a rotor 901 of the motor 9 penetrates through a passage of the motor supporting block 8 and extends out from a lower surface of the motor supporting block 8, and the rotor 901 can rotate in the passage. The rotor 901 extending out from the lower surface of the motor supporting block 8 is detachably connected to a cutting tool supporting block 10.

[0056] In the embodiment, the cutting tool supporting block 10 is provided with a rotor butt joint groove 1001, an inner wall of the rotor butt joint groove 1001 is provided with a first clamping structure, an outer wall of the rotor 901 of the motor is provided with a second clamping structure, and the first clamping structure and the second clamping structure are matched with each other to realize detachable connection between the rotor 9001 of the motor and the cutting tool supporting block 10. During cutting, the motor 9 drives the cutting tool supporting block 10 to rotate, so that the cutting tools (including a long cutting tool 11 and a disc cutting tool 12) rotate, and the running track of the cutting tools is accurately adjusted according to the boundary of a cutting template.

[0057] In the embodiment, after the cutting tool supporting block 10 is detached from the rotor 901, a drilling tool 14 can be installed on the rotor 901 to cut holes in the cloth, thereby facilitating punching and cutting of the cloth.

[0058] In the embodiment, the two types of cutting tools include a long cutting tool and a disc cutting tool, the preset included angle is 90°, and the predetermined angle is 90°. The rotating mechanism includes an electric control rotating shaft 13 and a travel switch connected with each other, under control of the travel switch, the electric control rotating shaft 13 rotates clockwise or counterclockwise, and the rotating angle is 90° each time. The electric control rotating shaft can be a motor or a separate electric control rotating shaft product (the electric control rotating shaft product is substantially the same as the motor), and the travel switch is used to control forward and reverse rotation of the motor. The specific control mode is as follows: first, the travel switch needs to be connected to a control circuit of the motor. The travel switch usually has two connection terminals, one for forward rotation and one for reverse rotation. When the motor needs to rotate forward, the travel switch is triggered, the control circuit sends a forward rotation signal to the motor, and the motor starts to rotate forward. When the motor needs to rotate reversely, the travel switch is also triggered, the control circuit sends a reverse rotation signal to the motor, and the motor starts to rotate reversely. The control unit of the embodiment is a control system of the cutting bed.

[0059] In the embodiment, the cutting knife assembly further comprises an air cooling mechanism arranged above the cutter and capable of blowing gas to the cutter. The air cooling mechanism comprises a nozzle mounting plate 1002 arranged on the side edge of the cutting knife supporting block 10 above the cutter, and a plurality of pressure air nozzles 15 arranged on the nozzle mounting plate 1002, each of which is communicated with a gas source through a gas pipe. During the cutting of the cloth, the cutting knife moves at a very high speed, and the temperature of the surface of the cutter increases after friction with the cloth. The cutter with excessively high temperature can affect the cutting edge of the cloth. The air cooling mechanism can spray cold air to the cutter to cool it, thereby avoiding the curling of the cutting edge of the cloth during the cutting.

[0060] In the embodiment, the cutting knife assembly further comprises a cloth pressing mechanism arranged on the back plate 2. The cloth pressing mechanism comprises a climbing rod 3, an electric control driving block 4, a damping column 6 and a spring 5. The climbing rod 3 is arranged on the back plate 2, the electric control driving block 4 passes through the climbing rod 3 and is capable of moving up and down along the climbing rod 3, the damping column 6 is arranged below the electric control driving block 4, and the spring 5 is arranged on the outer periphery of the damping column 6. The electric control driving block 4 moves up and down on the climbing rod 3, thereby driving the damping column 6 on the lower side to move up and down. During the cutting, the damping column 6 can press the cloth near the cutting area to prevent the displacement of the cloth during the cutting. The control unit is further used to control the movement of the electric control driving block.

[0061] In the embodiment, the cutting knife assembly further comprises a laser marking pen 7 and a laser image acquisition camera. The laser marking pen 7 and the laser image acquisition camera are both arranged on the upper shell 1. The control unit is used to control the direction of laser emission of the laser marking pen 7, so that the laser marking pen 7 always marks the contour edge of the cutting template. The laser image acquisition camera is used to acquire real-time images of the laser. The control unit calculates the real-time point coordinates of the laser according to the real-time images, and calculates the following coordinate points of the cutting knife according to the real-time point coordinates of the laser. Then, the control unit controls the real-time displacement (including the movement of the position and the rotation at the corresponding position) of the cutting knife, so that the cutter cuts more accurately. In the embodiment, the laser emission end of the laser marking pen is connected with a rotating shaft, and the control unit is used to control the rotation of the rotating shaft, thereby changing the direction of laser emission of the laser marking pen. The driving of the rotating shaft is based on the standard cutting piece pattern contour information stored in the cutting bed control system.

[0062] The specific positioning and identification method is as follows:

[0063] S1: input the pattern parameters of the cutting piece template into the control system of the cutting bed (image processing extracts the image edge contour);

[0064] S2: Collect the deviation value of the laser marker and the cutting knife in the X-axis direction; (the coordinate origin is a point vertically projected onto the cutting bed worktable at the center point of the laser marker and the cutting knife; taking the worktable as the reference surface, the horizontal movement of the upper shell 1 relative to the worktable is taken as the X-axis, and the vertical movement is taken as the Y-axis; both are on the upper shell 1, so the vertical movement Y-axis value is always consistent, without deviation, the deviation value of the X-axis is due to the interval between the installation positions of the two on the upper shell 1, that is, the deviation value is the distance between the two, which is a constant value);

[0065] S3: The control system of the cutting bed guides the laser marker to adjust the direction of the laser emission source according to the cutting template pattern parameters, so that it travels according to the contour edge of the cutting template;

[0066] S4: Collect the real-time image information of the laser travel, and calculate the real-time point coordinates of the laser according to the image information;

[0067] S5: According to the real-time point coordinates of the laser and the deviation value in step S2, the following coordinates of the cutting knife are calculated;

[0068] S6: The control system of the cutting bed controls the real-time displacement of the cutting knife according to the following point coordinates of the cutting knife;

[0069] In this embodiment, the threshold value of the cutting template image in step S1 is processed to obtain a binary image; the findContours() function in OpenCV is used to obtain the contour and store it in the form of a point vector. In step S3, the control system guides the laser marker to travel according to the contour point vector obtained in step S1.

[0070] In this embodiment, two tools are installed on the electric control rotating shaft; the electric control rotating shaft is controlled by a travel switch, and the angle range is controlled within 90° by controlling the clockwise or counterclockwise rotation of the electric control rotating shaft, so as to achieve the function of switching different types of tools.
