[0027] The present invention is further described in detail below through specific embodiments, which are only descriptive and not restrictive, and cannot be used to limit the protection scope of the present invention. The description is based on the actual use position of the photovoltaic module laminator in actual application.

[0028] like Figure 1-6 As shown, the photovoltaic module electric injection mechanism of the embodiment structure of the utility model includes an electrode assembly and an electrode assembly displacement driving device. The electrode assembly displacement driving device is used to drive the electrode assembly to move so that the electrode in the electrode assembly contacts the injection electrode sheet on the photovoltaic module to form an electrical connection. After the electric injection is completed, the electrode assembly displacement driving device drives the electrode assembly to return to its original position.

[0029] The electrode assembly preferably adopts the following structure, including an electrode column 481 and an electrode lifting device 490, the electrode column is connected to the output end of the electrode lifting device 490 through an insulating mounting plate 484, and the electrode lifting device drives the electrode column to rise and fall so that the electrode column contacts the injection electrode sheet on the photovoltaic module to implement electrical injection. The injection electrode sheet of the photovoltaic module can be a bus bar of the photovoltaic module, or a conductive sheet led from the bus bar. Preferably, the electrode column is elastically connected to the output end of the electrode lifting device. In this way, when the electrode column contacts the injection electrode sheet, the two are in soft contact and can be pressed relatively tightly. A spring can be set between the insulating plate and the output end of the electrode lifting device to achieve an elastic connection between the electrode column and the output end of the electrode lifting device. In another preferred embodiment, a conductive probe 482 is provided at the free end of the electrode column, a buffer spring 483 is provided on the outer sleeve of the electrode column, the spring is located between the insulating mounting plate and the probe, and a connecting thread is provided at the connecting end of the electrode column and the insulating plate. One end of the electrode column provided with the connecting thread passes through the connecting hole provided on the insulating mounting plate and is locked by a nut 485, so that the electrode column and the insulating plate can be movably connected. In this way, the spring is stuck between the probe and the insulating plate. When electricity is injected, the probe contacts the injection electrode sheet of the photovoltaic module to form an electrical connection, and the electrode column is connected to the power supply. When the probe contacts the injection electrode sheet, the electrode column rebounds and moves due to the reaction force, and the probe is pressed by the spring. The probe and the injection electrode sheet are in soft contact, and the photovoltaic module is not easily damaged. Preferably, a dual-axis electric cylinder or a cylinder is used as the electrode lifting device, which can increase the stability of the electrode assembly structure. It is best to set two electrode columns for each electrode assembly, and the probe is connected to the two electrode columns. The probe is in the shape of a long strip, so that the length of the probe is relatively long. The two electrode columns are arranged along the length direction of the probe. When the electrode column is opposite to the injection electrode sheet, the length direction of the probe is set perpendicular to the length direction of the injection electrode sheet. This can increase the compatibility of the electrode, reduce the difficulty of aligning the probe with the injection electrode sheet, and prevent the probe from missing the injection electrode sheet; at the same time, the two electrode columns can prevent the probe from rotating when it contacts the injection electrode sheet, thereby improving the success rate of electrical injection. When setting the probe, the center position of the probe is usually used as a reference position for position calculation. Since the positions of the probe and the electrode column on the X-axis and Y-axis are fixed, in the description of this patent, for the convenience of description, when explaining the alignment position with the injection electrode sheet on the photovoltaic module, it is uniformly referred to as the position with the electrode assembly. The electrode column or the electrode column and the probe constitute the electrode of the electrode assembly.

[0030] The electrode assembly displacement driving device can be a six-axis manipulator. When the manipulator is used, the photovoltaic assembly electric injection mechanism can be located next to the photovoltaic assembly production line. In the utility model, the electrode assembly displacement driving device preferably adopts an XY axis rectangular coordinate manipulator, including an X-axis servo drive mechanism 431 and a Y-axis servo drive mechanism 432. The Y-axis servo drive mechanism 432 is fixedly connected to the frame, and the X-axis servo drive mechanism 431 is fixedly arranged at the output end of the Y-axis servo drive mechanism 432. The output end of the X-axis servo drive mechanism 431 is fixedly connected to the electrode lifting device. In this way, the electrode assembly is driven by the Y-axis servo drive mechanism 432 to move along the Y axis, and the X-axis servo drive mechanism drives the electrode to move along the X axis, so that the electrode assembly can move within the XY rectangular coordinate, and then the electrode lifting device adjusts its height to achieve all-round movement. Two electrode assemblies can be set, the electrode of one electrode assembly is used to connect the positive pole of the power supply, and the electrode of the other electrode assembly is used to connect the negative pole of the power supply. The electrode lifting devices of the two electrode assemblies are both connected to the output end of the X-axis servo drive mechanism to synchronously drive the displacement of the two electrode assemblies. Alternatively, a pair of positive and negative electrodes may be provided in an electrode assembly, both of which are connected to the same electrode lifting device, the positive electrode being used to connect to the positive electrode of a power source, and the negative electrode being used to connect to the negative electrode of a power source.

[0031] Normally, the positive and negative electrodes are connected by a connecting rod 433. When two electrode assemblies are provided, an electrode assembly is provided at each end of the connecting rod, and the electrode assembly is fixedly connected to the connecting rod through an electrode lifting device. The output end of the X-axis servo drive mechanism is fixed to the connecting rod, and the output end of the Y-axis servo drive mechanism is fixedly connected to the X-axis servo drive mechanism. The Y-axis servo drive mechanism is fixedly arranged on the frame 110, and the length directions of the crossbeam and the connecting rod are arranged vertically. With the electrode assembly displacement drive device of the above structure, the Y-axis servo drive mechanism can drive the X-axis servo drive mechanism and the connecting rod to move along the length direction of the crossbeam, that is, the Y-axis direction, so as to adjust the position of the electrode assembly in the Y-axis direction, and the X-axis servo drive mechanism can drive the electrode assemblies on both sides to move in the direction of the X-axis to adjust the position of the electrode assembly in the X-axis. The electrode lifting device adjusts the position of the electrode in the Z-axis direction, thereby realizing all-round position adjustment of the electrode assembly.

[0032] It is best to set a mechanical correction mechanism 410 to correct the position of the photovoltaic module when the photovoltaic module reaches the pre-positioned position. In the field of photovoltaic module laminating machine technology, photovoltaic module correction devices are commonly used devices with various structures, all of which can be applied to the solution of this patent. In order to simplify the structure in this patent, the following structure is adopted, such as Figure 4As shown, each mechanical correction mechanism includes a correction drive 411, a guide wheel 412 and a correction frame 413. A guide wheel 412 is rotatably set at both ends of the correction frame 413. The correction frame is fixedly connected to the output end of the correction drive. A pair of correction mechanisms are correspondingly set for each photovoltaic module. The two correction mechanisms are respectively set at the two ends of the beam and are relatively set. The length direction of the correction frame is parallel to the X-axis. The output ends of the two correction drives are set facing each other. The four guide wheels form a retractable rectangle. The positions of the two correction mechanisms are relatively fixed. The correction drive is fixedly set on the frame. The photovoltaic module that deviates from the predetermined position is corrected by the correction mechanism so that it is located at the predetermined position to facilitate the operation of the electrode assembly displacement drive device. A cylinder is used as the correction drive. Since the photovoltaic modules are generally arranged in a line along the running direction when they are transmitted, the photovoltaic modules can be corrected to the predetermined position by only adjusting the position of the photovoltaic modules in the Y-axis direction.

[0033] like Figure 3 and Figure 6 As shown, it is best to set up a visual system 450 to identify and compare the position of the injected electrode sheet on each photovoltaic module. The visual system includes a camera 451 as an imaging device, a camera bracket 452, and a light source 453. The camera is fixedly arranged above the discharging transmission device 210 through the camera bracket. The lens 454 of the camera faces the predetermined position of the photovoltaic module. The control system controls the driving actions of the electrode assembly displacement drive device according to the position of the injected electrode sheet on the photovoltaic module collected by the camera, so that the electrode probe is aligned with the injected electrode sheet 120 and contacts. In the structure of the utility model, each group of electrode assemblies is linked. Therefore, as long as one camera is used to detect and identify the position of the injected electrode sheet of the photovoltaic module, the electrode probe on one side can be aligned with the injected electrode sheet, and the electrode probe on the other side can be aligned with the injected electrode sheet on the same side. In this device, a camera can also be set corresponding to each electrode assembly, and the position of the two opposite sides of the photovoltaic assembly can be detected. The two electrode assemblies are respectively provided with a Y-axis drive, which can increase the accuracy of alignment. The busbar on the photovoltaic assembly can be directly used as the injected electrode sheet.

[0034] It can be that one electrode assembly displacement drive device is provided with multiple pairs of electrode assemblies, and each photovoltaic assembly is equipped with a pair of electrode assemblies. The same electrode assembly displacement drive device drives all electrode assemblies to move synchronously on the X-axis and Y-axis to align with the injection electrode sheets set on each photovoltaic assembly. This structure is called a linkage electric injection mechanism. This structure requires that the position of the photovoltaic assembly is relatively accurate, otherwise it is easy for the electrode and the electrode sheet to be misaligned. It can also be as follows Figure 1 and 3As shown, multiple electrode assembly displacement drive devices are provided, each electrode assembly displacement drive device is equipped with a pair of electrodes, and each photovoltaic module is equipped with an electrode assembly displacement drive device and a pair of electrodes. This structure is called a single-machine electrical injection mechanism. A single-machine electrical injection mechanism is provided for each photovoltaic module. For example, when electrical injection is implemented for 7 photovoltaic modules, 7 single-machine electrical injection mechanisms are provided. The electrode assembly displacement drive device of each single-machine electrical injection mechanism drives its electrode assembly to move so that the position of the electrode assembly is relative to the predetermined position of the photovoltaic module. During electrical injection, the probe of each single-machine electrical injection mechanism performs electrical injection for the photovoltaic module at the corresponding position. The drive of the electrode assembly displacement drive device of each single-machine electrical injection mechanism is electrically connected to the control system respectively, and the 7 single-machine electrical injection mechanisms can implement electrical injection at the same time under the control of the control system. Using a single-machine electrical injection mechanism to implement electrical injection for multiple photovoltaic modules at the same time can implement electrical injection at the same time after the photovoltaic modules are in place, thereby improving the electrical injection efficiency of the photovoltaic modules.

[0035] It is best that each single-machine electrical injection mechanism is equipped with a power supply, the positive and negative electrodes of each electrical injection mechanism are respectively connected to the power supply, and the control switch of the power supply is electrically connected to the control system.

[0036] The photovoltaic module injection mechanism is preferably used in photovoltaic module packaging equipment, forming a component of the photovoltaic module packaging equipment, and implementing electrical injection on the hot photovoltaic modules after lamination and curing. The photovoltaic module packaging equipment at least includes a photovoltaic module lamination and curing unit, and the photovoltaic module electrical injection mechanism is located on the discharge side of the photovoltaic module lamination and curing unit. A photovoltaic module support platform is provided on the discharge side of the lamination and curing unit. When an XY-axis rectangular coordinate manipulator is used as an electrode assembly displacement driving device, the crossbeam of the photovoltaic module electrical injection mechanism is located above the photovoltaic module support platform and straddles the photovoltaic module support platform, thereby arranging the entire photovoltaic module electrical injection unit above the photovoltaic module support platform. The hot photovoltaic modules transmitted from the photovoltaic module lamination and curing unit are placed on the photovoltaic module support platform and then electrically injected by the electrical injection mechanism.
