[0014] The color registration method of the visual positioning hot stamping machine is to first set a mark that can be recognized by the CCD visual lens assembly on the substrate, and let the substrate and the electrochemical aluminum foil pass through the printing die. The printing die is installed on a mounting seat that can move left and right, front and back. The movement of the mounting seat is controlled by the CCD visual detection component to feed back the detected mark signal to the industrial computer to command the servo motor to drive. When the CCD visual lens assembly detects that the mark on the substrate is deviated, the servo motor will drive the mounting seat to allow the printing die connected to the mounting seat to make a quick adjustment of the position; when the position of the mark is correct, the printing die will accurately stamp the electrochemical aluminum foil on the substrate to achieve the effect of precise hot stamping or color registration.

[0015] Reference Figures 1 to 3 The hot stamping and color registration device using the above method includes an upper longitudinal beam 1 that can move relative to the frame, and the upper longitudinal beam 1 is provided with a mounting seat 2, a longitudinal slide rail 3, a longitudinal screw rod assembly 4, a printing mold 5 and a hot stamping power component 6 that drives the printing mold 5 to move. A servo motor 7 is installed at one end of the longitudinal screw rod assembly 4, and the longitudinal screw rod assembly 4 is transmission-connected to the mounting seat 2. The mounting seat 2 is composed of an upper and lower sliders. The lower slider 21 is transmission-connected to the longitudinal screw rod assembly 4, and the lower slider 21 is connected to the longitudinal slide rail 3 through the slide seat 8 at its bottom. A transverse slide rail 9 and a transverse screw rod assembly 10 are provided on the surface of the lower slider 21. A servo motor 11 is installed at one end of the transverse screw rod assembly 10. The transverse screw rod assembly 10 is transmission-connected to the upper slider 22, and the upper slider 22 is connected to the transverse slide rail 9 through the slide seat 8 at its bottom. The hot stamping power component 6 connected to the printing mold 5 is installed on the upper slider 22, and a CCD visual detection component 12 is provided next to the printing mold 5. When the CCD visual detection component 12 detects that the mark on the substrate is offset forward or backward, the servo motor 11 will rotate the horizontal screw assembly 10, driving the upper slider 22, the hot stamping power component 6 and the printing mold 5 to move forward or backward; when the CCD visual detection component 12 detects that the mark on the substrate is offset to the left or right, the servo motor 17 will rotate the longitudinal screw assembly 4, driving the lower slider 21, the upper slider 22, the hot stamping power component 6 and the printing mold 5 to move to the left or right; when the CCD visual detection component 12 detects that the mark on the substrate is in the correct position, the hot stamping power component 6 will drive the printing mold 5, allowing the printing mold 5 to accurately hot stamp the electrochemical aluminum foil on the substrate.

[0016] In addition, the CCD visual detection component 12 is installed on a slider component 13 that can move left and right and forward and backward. The installation position of the CCD visual detection component 12 can be adjusted by moving the corresponding parts of the slider component 13, so that it can conveniently and accurately detect marks at different positions on the substrate.

[0017] Reference Figure 4 and Figure 5, the slider assembly 13 includes a top slider 131, a middle slider 132, and a fixed block 133. A first lead screw assembly 14 for driving the middle slider 132 to move back and forth or left and right is installed on the fixed block 133. A transition block 134 is fixed on the middle slider 132, and a second lead screw assembly 15 for driving the top slider 131 to move left and right or back and forth is installed on the transition block 134. The CCD vision detection assembly 12 is installed on the top slider 131. The first lead screw assembly 14 and the second lead screw assembly 15 are arranged in a perpendicular cross pattern. When the first lead screw assembly 14 on the fixed block 133 rotates, it will drive components such as the middle slider 132, the transition block 134, the top slider 131, and the CCD vision detection assembly 12 to move back and forth or left and right. When the second lead screw assembly 15 on the transition block 134 rotates, it will drive components such as the top slider 131 and the CCD vision detection assembly 12 to move left and right or back and forth.

[0018] Furthermore, the fixed block 133 and the transition block 134 are respectively provided with counterbores 16 for the first lead screw assembly 14 and the second lead screw assembly 15 to move. The bottom parts of the middle slider 132 and the top slider 131 are respectively provided with bumps 17 that are threadedly connected to the first lead screw assembly 14 and the second lead screw assembly 15. The bumps 17 can move within the counterbores 16. When the first lead screw assembly 14 and the second lead screw assembly 15 rotate, they will respectively drive the middle slider 132 and the top slider 131 connected to the bumps 17 to move, thereby adjusting the position of the CCD vision detection assembly 12.

[0019] To ensure that the CCD vision detection assembly 12 is stably and firmly fixed in a certain position and prevent it from loosening or shifting during operation, locking pieces 18 are provided between the fixed block 133 and the middle slider 132, and between the transition block 134 and the top slider 131. The locking pieces 18 are fixed on the fixed block 133 or the transition block 134, and screw holes 20 corresponding to the locking screws 19 of the locking pieces 18 are provided on the middle slider 132 and the top slider 131. When the locking screws 19 are screwed into the screw holes 20, the fixed block 133 and the middle slider 132, and the transition block 134 and the top slider 131 will be relatively fixed together, and there will be no loosening or shifting between them.

[0020] To enable the CCD vision detection assembly 12 to have a larger range of position adjustment to meet the production needs of more products, the slider assembly 13 is installed on a bracket that can be adjusted to move left and right, back and forth, and up and down. The bracket is mainly composed of a cross bar 24, a longitudinal bar 25, and a vertical bar 26 connected together. The cross bar 24, the longitudinal bar 25, and the vertical bar 26 can be adjusted left and right, back and forth, and up and down respectively.

[0021] Furthermore, to optimize the structure of this mechanism, the upper longitudinal beam 1 is of a hollow structure, and a transmission block 23 connected to the hot stamping power component 6 passes through the mounting seat 2 and the upper longitudinal beam 1 to be connected to the printing die 5.
