The CPU module 802 of the circuit device captures a cake image according to the photographing unit to identify the size and position of the cake, such as the length of a square cake. The width is matched to set the compensation value added after each cut to increase the moving distance of the cutting knife 66 to compensate for the deviation of the cake caused by the thickness of the knife. For example, the size of the square mousse cake in the eighth picture is: 570mm * 370mm, the size of 6 8-inch mousse cakes to be cut is: 180mm * 180mm, two cutting methods can be set. The first cutting method is suitable for Qifeng cakes, sponge cakes and long bars with soft cakes. For cake rolls, the smaller the shift, the smaller the compensation value. As shown in the eighth figure, the first and second knives cut the edges first, and the two edges on the leftmost and top edges are trimmed first before starting. Formally cut. During cutting, the knife plate 662 can be controlled to move left and right in the X axis and move up and down in the Z axis to cut the knife. Each cut will increase the compensation value to compensate for the cake deviation caused by the thickness of the knife. If the compensation value is 5mm, At the beginning of the three-knife, the distance moved by the titanium alloy blade 662 becomes 180 + 5 = 185mm to offset the deviation of the cake caused by the thickness of the cutter, and so on; when the left and right cutting is completed, the blade 662 can be controlled by Use Y-axis forward and backward displacement control, and coordinate with the Z-axis moving up and down knife cutting, and each cut as described above will increase the compensation value to compensate for the cake offset error caused by the thickness of the knife, if so, according to the The setting parameters can be automatically cut into cakes of the same size with the cooperation of the X-axis drive assembly 71, the Y-axis drive assembly 72, and the Z-axis drive assembly 73. The second cutting rule is suitable for products with large displacement such as frozen cheesecakes and frozen mousse cakes with relatively hard cakes. It can minimize the displacement. As shown in the ninth figure, the lower knife starts from the center and is on the X axis. With the cooperation of the driving unit 71, the Y-axis driving unit 72, and the Z-axis driving unit 73, the cutting is performed in the left and right and up and down directions, and the compensation value can also be set. If so, the operator can choose the above two different cutting methods to reduce the offset error depending on the softness and hardness of the cake. It can also be set to compensate for each cut, or only once for each two or three cuts. The situation of the shift is decided.

In addition, the cake cutting device of the present invention further includes an LED warning device 93, which is located on the side of the lighting hood 22 above the emergency stop switch 92. It can use sound and light effects to warn of abnormal conditions during any operation, such as failure to perform initialization The emergency stop switch 92 is pressed Next, the cutting unit 6 is prohibited from moving while the cover 226 is open, and the position of the carrier 3 is prohibited from closing the cover 226.

To sum up, the cake cutting device of the present invention has the following advantages:

1. With automatic camera positioning function, the size of the square cake (including rectangle) and the center of the round cake are recognized through the visual recognition unit, and if the cake is placed outside the visual recognition range, an alert will be issued, and the cutting machine will not perform the cutting task .

2. The X-axis (the blade moves left and right), the Y-axis (the bearing moves back and forth), the Z-axis (the blade moves up and down), and the R-axis (the blade rotates), the cutting speed can be set, and single-action cutting can be set 、 Fully automatic cutting can also simulate the demonstration action, which is convenient for the operator to check whether its setting is correct.

3. For square cake, you can set the compensation value to increase after each cut or several cuts to compensate for the deviation of the cake caused by the thickness of the cutter. For a round cake, the center of the circle can be automatically determined within the range of the carrier, and each knife is on the center of the circle when cutting, so that the cake can be evenly cut out of the set number and size.

In summary, the cake cutting device of the present invention can indeed achieve the purpose of the invention and meet the patent requirements. However, the above is only a preferred embodiment of the present invention. Any modification and change based on the present invention should still be applied.
