[0033] Please refer to Figure 4, the continuous copper bar heat shrinkable tube automatic heating device further includes a chain tensioning assembly 5.

The chain tensioning assembly 5 includes: a first fixing plate 51, the first fixing plate 51 extends along the width direction of the fixing table 1, and both ends of the first fixing plate 51 are respectively connected to the opposite side walls of the first track 31.

[0036] By adopting the above technical solution, during the process of tensioning the drive chain, by adjusting the design of the spring 58, the spring 58 applies a thrust to the second track 32 by abutting against the support plate 55, causing the second track 32 to move outward, so that the drive chain always remains in a tensioned state.

[0037] Please refer to Figure 1 and Figure 3 , the continuous copper bar heat shrinkable tube automatic heating device further includes a power mechanism 6. The power mechanism 6 includes: an installation box 61 installed on the first track 31. A power space, a driving port and a maintenance port communicating with the power space are arranged in the installation box 61, and each driving sprocket 33 is installed in the power space; a driving member 62 installed in the power space, the driving member 62 is arranged at an interval from each driving sprocket 33; a motor protection component 7 arranged at an interval from the driving member 62, the motor protection component 7 is drivingly connected to the driving member 62, and the motor protection component 7 is installed in the power space.

[0038] By adopting the above technical solution, during the process of the conveying mechanism 3 driving the copper bar into the heating chamber 22, through the design of the driving member 62, mechanized driving is realized by the rotation of the driving member 62, improving the production efficiency.

[0039] Among them, the driving member 62 includes a variable frequency motor and a reducer, and the variable frequency motor is electrically connected to the controller.

[0040] Please refer to Figure 3 and Figure 5, the motor protection assembly 7 includes: a driving sprocket 71, the driving sprocket 71 is drivingly connected to the driving member 62, and the driving sprocket 71 is installed in the power space; a first boss 72, the first boss 72 is connected to the driving sprocket 71; a second boss 73, the second boss 73 is snap-connected to the first boss 72; a connecting shaft 74, the connecting shaft 74 passes through the second boss 73 and is connected to the second boss 73, and one end of the connecting shaft 74 away from the second boss 73 is connected to one of the transmission sprockets 33, the driving sprocket 71 is rotatably arranged on the connecting shaft 74, and the first boss 72 is rotatably arranged relative to the connecting shaft 74; a plurality of connecting rods 75, the plurality of connecting rods 75 are arranged at intervals around the circumference of the second boss 73, the plurality of connecting rods 75 are arranged on the side of the second boss 73 away from the first boss 72, and the plurality of connecting rods 75 extend along the extending direction of the connecting shaft 74; a fixing seat 76, the fixing seat 76 is arranged at an interval from the second boss 73, and the plurality of connecting rods 75 are slidably arranged with the fixing seat 76; a limiting rod 77, the limiting rod 77 extends along the extending direction of the connecting shaft 74, and the limiting rod 77 is slidably arranged relative to the fixing seat 76; a limiting nut 78, a thread is provided on the limiting rod 77 along the extending direction of the limiting rod 77, the limiting nut 78 is threadedly connected to the limiting rod 77, and the limiting nut 78 is installed on the side of the fixing seat 76 away from the second boss 73.

[0041] By adopting the above technical solution, through the design of the first boss 72 and the second boss 73, during the transmission of the copper bar, in order to prevent the problem of the motor being damaged due to a failure during the transmission of the transmission chain, when the chain transmission gets stuck, the driving member 62 will continuously output and drive the driving sprocket 71 to rotate. When it gets stuck, the second boss 73 will be limited and stop rotating. At this time, only the driving sprocket 71 and the first boss 72 rotate. Because the first boss 72 and the second boss 73 are snap-connected, when the second boss 73 is limited, the protruding part of the first boss 72 will disengage from the second boss 73. At this time, the driving member 62 will not reach an overloaded state, avoiding overheating and even burning of internal components such as bearings and windings of the driving member 62.

[0042] Please refer to Figure 1 , the continuous copper bar heat shrinkable tube automatic heating device further includes a control system, and the control system includes: a temperature sensor, the temperature sensor is arranged in the heating cavity, and the temperature sensor is electrically connected to the controller; an image collector, the image sensor is electrically connected to the controller, the controller is electrically connected to the variable frequency motor, and the image collector is used to collect the forming state of the heat shrinkable tube on the copper bar.

[0043] By adopting the above technical solution, through the design of the image collector and the temperature sensor, during the heating and forming process of the copper bar heat shrinkable tube, the image collector continuously collects the real-time state of the copper bar heat shrinkable tube, and controls the rotation speed and rotation direction of the variable frequency motor according to the real-time state of the copper bar heat shrinkable tube.

[0044] Among them, during the continuous heating process of the copper busbar heat shrinkable tube, if the heat shrinkage effect in some areas is not ideal (such as incomplete heat shrinkage), it may affect the entire production process and product quality. To avoid this situation, we use an image collector to monitor the status of the heat shrinkable tube in real time and adjust the parameters (such as motor speed, heating time, and temperature) during the heating process through a control algorithm to ensure that each copper busbar heat shrinkable tube achieves the best heat shrinkage effect.

[0045] First, a high-resolution image collector is installed at the outlet of the heating chamber 22 or on the key path of the copper busbar to continuously collect the appearance images of the heat shrinkable tube; the image collector should be able to capture the heat shrinkage situation of the heat shrinkable tube, including whether the heat shrinkage is uniform, whether there are bubbles, wrinkles, or other defects; Through image processing algorithms (such as edge detection, morphological analysis, deep learning models, etc.), each image frame is analyzed to determine whether the heat shrinkage of the heat shrinkable tube is in place. The specific analysis points include: whether both ends of the heat shrinkable tube shrink evenly and whether there are irregular heat shrinkage areas; When the heat shrinkage amount and at both ends of the heat shrinkable tube are quite different, it indicates that the heat shrinkage is uneven. We use the following formula to judge the uniformity of heat shrinkage: Among them, : The heat shrinkage amount at one end of the heat shrinkable tube; : The heat shrinkage amount at the other end of the heat shrinkable tube; : The average value of the heat shrinkage amounts at both ends of the heat shrinkable tube; If exceeds the preset threshold (such as 10%), it is judged that the heat shrinkage is uneven, and the following operations are performed: reduce the motor speed and adjust the heating temperature. By slowing down the rotation speed of the motor, the copper busbar stays in the heating chamber for a longer time to ensure that the heat shrinkable tube shrinks sufficiently; by increasing the temperature gradient in the heating chamber, ensure uniform heating at both ends.

[0046] If the shape of the heat shrinkable tube deviates, the system needs to judge according to the deviation between the shape of the heat shrinkable tube and the expected shape. The following formula is used to calculate the deviation: Among them, Misalignment area: The area of the region that does not conform to the expected shape.

[0047] Total area: The total area of the heat shrinkable tube.

[0048] If the shape deviation If it exceeds the set threshold (e.g., 5%), it indicates that the shape of the heat-shrinkable tube is incorrect, and the motor will stop: If the shape of the heat-shrinkable tube has a serious deviation, first stop the operation of the motor to prevent more unqualified copper bars from being produced during continuous operation. The motor will reverse and reheat: After stopping, the motor will reverse, return the copper bar to the heating chamber, and reheat it until the shape of the heat-shrinkable tube returns to normal.

[0049] Based on the real-time image feedback, the system determines whether the heat-shrinkable tube is sufficiently heated. If the heat-shrinkable tube is not heated enough, the system will dynamically adjust the motor speed through a formula to ensure that the copper bar receives sufficient heating; Among them, : is the motor speed, which controls the movement speed of the copper bar; : is the heat-shrinkage error, indicating the degree of incomplete heat-shrinkage. The larger the error, the more incomplete the heat-shrinkage; is a constant that determines the adjustment range of the motor speed. When the heat-shrinkage error exceeds the preset tolerance (e.g., 5%), the system will slow down the motor speed and increase the residence time of the copper bar in the heating chamber to ensure that the heat-shrinkable tube shrinks sufficiently.

[0050] If the shape deviation of the heat-shrinkable tube is too large, the system will reverse the motor and send the copper bar back to the heating chamber for reheating. The control conditions are: If , the motor stops rotating, and then the motor reverses; Among them, is the shape deviation of the heat-shrinkable tube; is the preset maximum deviation tolerance. When it is exceeded, the reversal will be triggered; If the shape deviation exceeds the set maximum tolerance value (e.g., 5%), the system will determine that the heat-shrinkage is not in place and start the control of reversing the motor.

[0051] To ensure that the heat-shrinkable tube receives sufficient heat and completes heat-shrinkage, the system will dynamically adjust the heating time according to the heat-shrinkage error. The heating time adjustment formula is as follows: Among them: : the original heating time; : the heating time increment adjusted according to the image feedback; If the system detects that the heat-shrinkage is not in place and the heat-shrinkage error is large (e.g., shape deviation or heat-shrinkage uniformity problem), the system will extend the heating time.
