[0002] With the rapid development of photovoltaic technology and its wide range of applications, the market demand for high-power modules is also increasing. Reducing module packaging losses and increasing module output power have become the current research trends. Half-cell technology is a technology that increases module power by reducing the size of cells and reducing series resistance losses. Currently, half-cell technology is mainly used through laser scribing, and the efficiency of modules is improved by increasing the packaging density of cells inside the module. After laser scribing, stress problems are prone to occur on the cut surface. In order to reduce the occurrence of hidden cracks after welding, the welding strip needs to be bent and the welding stress distribution needs to be optimized.

[0003] The welding mechanism currently used to bend the welding strip, the size of the bend is determined by the mechanical structure itself, and it is easy to cause the bending to fail to meet the actual process requirements due to wear and jamming. The deformation of the welding strip bending product is currently checked offline, and the measurement process requires the equipment to be shut down. In addition, due to the current equipment, its measurement can only be carried out by random inspection, and quality abnormalities in production cannot be discovered in time, which poses a serious quality risk.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0022] Embodiment 1

[0023] like Figure 1-2 As shown, a system for bending a welding strip provided in this embodiment, wherein the structure and part of the supporting mechanism for pulling the welding strip are omitted in the accompanying drawings. It includes a welding strip bending mechanism 1, a detection mechanism 2 and a control unit 3. The welding strip 4 is pulled out from the welding strip guide wheel by the welding machine puller, the welding strip bending mechanism 1 is used to adjust the bending parameters and bend the welding strip 4, the welding strip bending mechanism 1 bends the welding strip 4, and the welding strip 4 is pulled out by the welding strip puller after bending, the detection mechanism 2 is used to detect the bending state of the bent welding strip 4, and the control unit 3 is used to process the data of the detection mechanism 2, the control unit 3 and the detection mechanism 2 are electrically connected, and the detection mechanism transmits the detection data to the control unit for analysis and judgment. In the technical solution of this embodiment, first, the welding strip bending mechanism enables the system to adjust the bending parameters and bend the welding strip, and the operator can adjust the bending parameters of the welding strip according to actual needs to ensure that the bending quality of the welding strip meets the required standards for subsequent welding. This flexibility enables the system to adapt to different welding requirements, thereby improving production efficiency and product quality. Then, the role of the detection mechanism is to detect the bent welding strip and feed back its parameters to the control unit for judgment and processing. Through the feedback of the detection mechanism and the data processing of the control unit, the operator can adjust the system parameters or make necessary corrections in time to ensure the stability and consistency of the welding quality. The system of this embodiment can monitor the bending of the welding strip during the production process in real time and detect any potential quality problems or abnormal conditions in time. In addition, the control unit can also store and analyze historical data to provide a reference for the optimization of the production process. The entire test process adopts online inspection, and the measurement process does not require the equipment to be shut down.

[0024] Preferably, the control unit 3 is also used to adjust the bending parameters of the welding strip bending mechanism 1, and the control unit 3 is electrically connected to the welding strip bending mechanism 1. The control unit in this scheme is not only used to process the data of the detection mechanism, but also to adjust the bending parameters of the welding strip bending mechanism. This integrated control function makes the system more intelligent and automated. By adjusting the bending parameters by the control unit, the system can more accurately control the bending process of the welding strip, thereby further improving the quality and production efficiency of the product. The control unit can automatically adjust the working mode of the welding equipment or issue an alarm according to the detected bending state and other parameters of the welding strip to prevent potential quality problems. In addition, the control unit can also store and analyze historical data to provide a reference for the optimization of the production process.

[0025] Specifically, the detection mechanism 2 of this embodiment includes a first infrared emission processor 21 for emitting infrared and receiving reflected infrared data, and the first infrared emission processor 21 is electrically connected to the control unit 3. After the welding strip is bent, when passing through the first infrared emission processor, the infrared light irradiates the welding strip, and the length and height change data of the bending part of the welding strip are obtained due to different reflection coefficients. The detection mechanism can realize high-precision detection of the bending state of the welding strip. Infrared technology has the characteristics of non-contact and high sensitivity, and can accurately detect the length and height change of the bending of the welding strip, thereby realizing accurate control of the quality of the finished welding strip. Further, the detection mechanism 2 also includes a second infrared emitter 22 for emitting infrared and receiving reflected infrared data, and the second infrared emission processor is electrically connected to the control unit 3. By introducing the second infrared emitter, the system realizes dual infrared detection, thereby improving the comprehensiveness and accuracy of the detection. The dual detection mechanism can more comprehensively monitor the changes and abnormal conditions in the welding process, thereby improving the quality control ability of the system.

[0026] By adjusting the distance of the transmitting end, the effect of infrared detection can be optimized. A longer distance may cause signal attenuation, but it can also provide a wider detection range and more comprehensive information. A closer distance may improve signal strength and detection accuracy. Therefore, according to specific needs and actual conditions, the optimal transmitting end distance can be selected to achieve the best detection effect and performance. Preferably, the distance between the transmitting end of the first infrared transmitting processor 21 and the detection surface is 20-50cm.

[0027] Specifically, the solder strip bending mechanism 1 includes a clamping unit 11 for clamping the solder strip and a bending unit 12 for bending the solder strip, the clamping unit 11 is arranged on one side of the bending unit 12, and the bending unit 12 is electrically connected to the control unit 3, wherein the clamping unit 11 and the bending unit 12 are fixedly mounted on the platform 13.

[0028] Specifically, the bending unit 12 includes a bending bracket 121, a bending cylinder 122 is installed on the bending bracket 121, a bending head 123 is installed on the bending cylinder 122, and the bending unit 12 also includes a bending base 124 matched with the bending head 123, the bending base 124 is installed on the bending bracket 121, and the bending cylinder 122 is electrically connected to the control unit 3. The bending cylinder and the control unit are electrically connected to achieve precise control of the bending process. Through the electrical connection between the control unit and the bending cylinder, the opening, closing and pressure application of the bending cylinder can be controlled. The control unit compares the data transmitted by the detection mechanism with the basic data to obtain whether the bending of the welding strip meets the process requirements. If the requirements are not met, the bending cylinder of the feedback bending component automatically adjusts the downward pressure of the bending component according to the data until the bent welding strip that meets the technical requirements is obtained.

[0029] Preferably, an alarm 5 is also included, and the alarm 5 is electrically connected to the control unit 3. The introduction of the alarm enables the system to monitor abnormal conditions in the welding process in real time and issue an alarm in time. Whether it is abnormal welding parameters, equipment failure or other abnormal conditions, the alarm can respond quickly and issue an alarm to remind the operator to pay attention and take necessary measures in time. This real-time monitoring and alarm function helps to prevent production accidents and reduce the occurrence of quality problems, thereby improving production safety and product quality.
