[0022] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] The present application embodiment provides a hot stamping plate registration device, referring to Figure 1 ,include:

[0024] Code disc 1, registration photoelectric sensor 5, wherein:

[0025] The code disc 1 is disc-shaped and is sleeved on the central axis 2 at one end of the hot stamping roller 3. The diameter of the code disc 1 is the same as the diameter of the hot stamping roller 3. The rotation center line of the code disc 1 and the rotation center line of the hot stamping roller 3 are located on the same straight line. A plurality of scale lines 4 are provided on the side of the code disc 1 away from the central axis 2.

[0026] The registration photoelectric sensor 5 is arranged opposite to the code disc 1 , and the transmitter and the receiver of the registration photoelectric sensor 5 face the side of the code disc 1 where the scale line 4 is arranged.

[0027] Specifically, the code disc 1 is designed to be disc-shaped and is tightly mounted on the central shaft 2 at one end of the hot stamping roller 3 to ensure that the two rotate synchronously. The diameter of the code disc 1 is consistent with the diameter of the hot stamping roller 3 to ensure stability during rotation. In addition, the rotation center line of the code disc 1 is strictly aligned with the rotation center line of the hot stamping roller 3, which helps to reduce errors during rotation and improve registration accuracy.

[0028] On the side of the code disc 1 away from the central axis 2, a plurality of scale lines 4 are carefully arranged. These scale lines 4 are clear and uniform, providing a reliable reference for the recognition of the registration photoelectric sensor 5. The hot stamping roller 3 is located on the side part between two adjacent scale lines 4, and a hot stamping plate is installed respectively. This design enables each hot stamping plate to correspond to a specific scale line 4, which is convenient for subsequent registration operations.

[0029] The registration photoelectric sensor 5 is placed at a position opposite to the code disk 1, with its transmitter and receiver facing the side of the code disk 1 with the scale lines 4. The sensor recognizes the scale lines 4 by emitting infrared light and detecting the reflected light signal. When the hot stamping roller 3 rotates, the registration photoelectric sensor 5 will continuously detect the scale lines 4 passed by and output corresponding signals.

[0030] Before each hot stamping, the control system receives the signal from the registration photoelectric sensor 5 to identify the current position of the hot stamping roller 3. Then, by calculating the angle difference between the hot stamping plate and the preset position, the control system sends a command to the servo motor to drive the hot stamping roller 3 to rotate to the correct angle. In this process, the high-precision control capability of the servo motor ensures that the hot stamping plate can be accurately aligned with the preset position.

[0031] During the hot stamping process, the registration photoelectric sensor 5 will also count the scale lines 4 passed. This function not only helps to monitor the progress of hot stamping in real time, but also can collect hot stamping data to provide a basis for subsequent process analysis and optimization. By analyzing the data, we can understand the movement law of the hot stamping plate during the hot stamping process, further optimize the registration parameters, and improve the quality and efficiency of hot stamping.

[0032] In some embodiments, the registration photoelectric sensor 5 is connected to a control system, and the control system is connected to a servo motor that drives the hot stamping roller 3 to rotate;

[0033] The control system includes: a signal receiving module, which is used to receive the signal emitted by the registration photoelectric sensor 5; a data processing module, which is used to decode and process the received signal, obtain the current rotation angle and position of the hot stamping roller 3, and calculate the correct angle that the hot stamping roller 3 needs to rotate according to the preset hot stamping plate position and angle; a control instruction generation module, which is used to generate corresponding control instructions based on the calculation results of the data processing module; a communication interface, which is connected to the servo motor, and is used to realize the sending of the control instructions and the receiving of feedback signals.

[0034] Specifically, the structure of the control system includes: signal receiving module: this module is responsible for receiving the signal sent by the registration photoelectric sensor 5. These signals usually contain information about the position of the scale line 4 and the rotation state of the hot stamping roller 3. The signal receiving module converts these signals into electrical signals or digital signals that can be recognized by the control system. Data processing module: after receiving the signal, the data processing module will decode and process these signals. It will first identify the current rotation angle and position of the hot stamping roller 3, and then calculate the correct angle that the hot stamping roller 3 needs to rotate according to the preset hot stamping plate position and angle. Control instruction generation module: based on the calculation results of the data processing module, the control instruction generation module will generate corresponding control instructions. These instructions include parameters such as the rotation direction, rotation speed and rotation angle of the servo motor. Communication interface: the control system is connected to the servo motor through the communication interface to realize the sending of instructions and the reception of feedback signals. The communication interface usually adopts a standard electrical interface or communication protocol to ensure the accurate transmission of instructions.

[0035] The functions of the control system include: Real-time monitoring and adjustment: The control system can receive the signals of the registration photoelectric sensor 5 in real time, and monitor the position of the hot stamping roller 3 in real time according to these signals. Once a deviation is found, the control system will immediately calculate the adjustment amount and make precise adjustments through the servo motor to ensure that the hot stamping plate always remains in the correct position. Improve registration accuracy: By accurately controlling the rotation angle and speed of the servo motor, the control system can achieve high-precision hot stamping plate registration. This can not only improve the quality and consistency of the hot stamping pattern, but also reduce the scrap rate and improve production efficiency. Automation and intelligence: The introduction of the control system makes the hot stamping plate registration process more automated and intelligent. The operator only needs to set the preset position and parameters, and the control system can automatically complete the registration and hot stamping work, reducing the dependence on the operator and the skill requirements. Data recording and analysis: The control system can also record data during the hot stamping process, such as the rotation angle, speed and registration accuracy of the hot stamping roller 3. These data can be used for subsequent process analysis and optimization, providing strong support for further improving the quality and efficiency of hot stamping.

[0036] In some embodiments, the registration photoelectric sensor 5 is a reflective photoelectric sensor, including a transmitter and a receiver located in the same device.

[0037] Specifically, the registration photoelectric sensor 5 is mainly composed of the following parts: Transmitter: The transmitter is one of the core components of the photoelectric sensor, which is responsible for emitting light signals. The transmitter usually contains a light source, such as a light emitting diode (LED) or other semiconductor light sources, which can emit light of a specific wavelength, usually infrared light or visible light. Receiver: The receiver is located in the same device as the transmitter and is used to receive the light signal emitted by the transmitter. When the light signal is reflected by a low-reflectivity material, the receiver detects this change. The receiver usually contains photoelectric conversion elements, such as photodiodes or phototransistors, which can convert the received light signal into an electrical signal. Optical elements: In front of the receiver, optical elements such as lenses and apertures are usually installed. These elements are used to focus and adjust the light signal to ensure that the light signal can be accurately received by the receiver. Detection circuit: The detection circuit is another key part of the photoelectric sensor, which is responsible for processing the electrical signal converted by the receiver. The detection circuit can filter out noise and interference signals, extract effective light signal changes, and convert them into digital signals or analog signals that can be recognized and processed by the control system.

[0038] The functions of the registration photoelectric sensor 5 include: detecting position and angle: by emitting and receiving light signals, the registration photoelectric sensor 5 can monitor the position and angle of the hot stamping roller 3 in real time. When the hot stamping roller 3 rotates, the registration photoelectric sensor 5 detects the change of the scale line 4 on the code disk 1, thereby determining the current position of the hot stamping roller 3. Providing accurate feedback: the registration photoelectric sensor 5 converts the detected position information into an electrical signal and feeds it back to the control system in real time. Based on these feedback signals, the control system calculates the correct angle that the hot stamping roller 3 needs to rotate and makes precise adjustments through the servo motor. Improving registration accuracy: Since the photoelectric sensor has the characteristics of high sensitivity and high resolution, it can accurately detect tiny position changes. This enables the registration photoelectric sensor 5 to achieve high-precision hot stamping plate registration and ensure the accuracy and consistency of the hot stamping pattern. Automation and intelligent support: by integrating the registration photoelectric sensor 5, the hot stamping plate registration device can achieve automated and intelligent operation. The control system can automatically adjust the position and angle of the hot stamping roller 3 according to the feedback signal of the photoelectric sensor without manual intervention, thereby improving production efficiency and reducing human errors.

[0039] In some embodiments, the side of the code disk 1 where the scale lines 4 are provided is made of a smooth metal material, and the reflection coefficient of the scale lines 4 is lower than the reflection coefficient of the side where the scale lines 4 are provided.

[0040] In some embodiments, the code disc 1 is integrally formed with the hot stamping roller 3 and the central shaft 2;

[0041] Alternatively, screw holes are provided at the positions where the code disc 1 contacts the central axis 2, and the code disc 1 and the central axis 2 are fixedly connected by screws.

[0042] In some embodiments, a gap is provided between the code disc 1 and the hot stamping roller 3 .

[0043] In some embodiments, the scale lines 4 extend along the thickness direction of the code disc 1 .

[0044] In summary, compared with the prior art, the hot stamping plate registration device provided by the above technical solution sets a code disc 1 on the central axis 2 at one end of the hot stamping roller 3, sets scale lines 4 on the side of the code disc 1, and uses the registration photoelectric sensor 5 to collect data of the scale lines 4 to obtain the current rotation angle and position of the hot stamping roller 3, thereby performing efficient and accurate registration. This solves the problem that the manual positioning method commonly used in the prior art easily causes unstable registration of hot stamping, and cannot perform efficient and accurate registration, thereby increasing the cost of hot stamping.
