[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-3 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0019] A self-testing hot-pressing mechanism for a busbar includes a back plate 42. An electromagnetic hot-pressing machine 47 is mounted on the upper part of one side of the back plate 42, and a primary buffer assembly is mounted on the lower part. A secondary buffer assembly is mounted on the other side of the back plate 42. The primary buffer assembly includes a first buffer plate 43 placed on the back plate 42. Slide rails are provided on both sides of the first buffer plate 43. A first buffer block is mounted on the first buffer plate 43 via the slide rails. A buffer spring 431 is connected above the first buffer block, and the upper end of the buffer spring 431 is connected to a limiting block 432 fixed to the back plate. When the bottom of the first buffer block is subjected to force, it compresses the buffer spring 431, achieving vertical displacement on the first buffer plate 43. The limiting block 432 is gate-shaped and surrounds the outer side of the upper end of the first buffer plate 43. A limiting screw 44 is vertically mounted on the limiting block 432, and the lower end of the limiting screw 44 extends downward beyond the bottom of the limiting block 432. When the first buffer plate moves upward and the buffer spring 431 is compressed, the top surface of the first buffer plate will abut against the bottom of the limiting screw 44. At this time, the limiting screw 44 will play a limiting role. An adapter block 433 is connected to the outside of the first buffer plate. A ceramic pressure head 434 is provided at the bottom of the adapter block 433. The copper coil welding head 471 of the electromagnetic hot iron 47 is sleeved on the ceramic pressure head 434.
[0020] The secondary buffer assembly includes a second buffer plate 41 located on the other side of the back plate 42. A slider 421 is connected between the second buffer plate 41 and the back plate, and the second buffer plate 41 and the back plate 42 are connected by buffer springs 431 on both sides of the slider. When the first buffer assembly is compressed into place and continues to be subjected to force, it will drive the back plate 42 to compress the buffer springs 431 on both sides of the slider, thereby moving the back plate 42 on the slider.
[0021] The electromagnetic hot iron 47 is equipped with a cooling component, which adopts an air-cooled form. The electromagnetic hot iron 47 is equipped with an air-cooled air inlet 46 and an air-cooled air outlet 47. Compared with the traditional water cooling, the air-cooled form can further simplify the complexity of the equipment's connection pipeline and reduce costs while ensuring the cooling effect.
[0022] To maintain and stabilize the position of the copper coil welding head of the electromagnetic heating machine during heating, preventing direct contact with the busbar and damage, and also to better protect the welding head, the copper coil welding head 471 of the electromagnetic heating machine is fitted onto the ceramic pressure head 434 on the primary buffer assembly. The bottom of the ceramic pressure head 434 extends outside the copper coil welding head. Based on the application scenario of this utility model, the final distance of the bottom of the ceramic pressure head 434 extending from the copper coil welding head is adjusted to be maintained between 1-2mm. That is, during heating, the copper coil welding head and the busbar are never in contact, maintaining a distance of 1-2mm.
[0023] In this embodiment, the ceramic pressure head 434 extends downward and is positioned outside the first buffer block. The ignition mechanism, in conjunction with the primary and secondary buffer components, applies pre-pressure to the ignition position after accurate positioning during operation, ensuring that the manifold does not shift during ignition, further improving the accuracy of the ignition position. The buffer spring and limiting screw also ensure that the pre-pressure during ignition is not excessive and could damage the manifold.
[0024] To achieve automated hot stamping efficiency, a visual monitoring component 3 is selectively installed on the upper outer side of the electromagnetic hot stamping machine 47. The visual monitoring component 3 is an image acquisition lens, which first acquires and locates the position of the busbar, providing a basis for the hot stamping mechanism to move to the required position.
[0025] The busbar self-testing and hot-pressing mechanism of this utility model is typically used in conjunction with a transfer line. Figure 3 The diagram illustrates a device with the aforementioned busbar self-testing and heat-pressing mechanism, comprising a frame and a transfer line 7 mounted above the frame. The busbar self-testing and heat-pressing mechanism is placed on the transfer line 7 via a movable frame 1, and reciprocates horizontally on the transfer line 7. To improve heat-pressing efficiency, the number of busbar self-testing and heat-pressing mechanisms on the transfer line 7 is determined by the specific number of busbars to be heat-pressed. The back side of the second buffer plate 41 is connected to a linear module 11 placed on the movable frame 1. The linear module 11 operates, driving the busbar self-testing and heat-pressing mechanism to reciprocate vertically.
[0026] A transmission mechanism 6 for transmitting photovoltaic modules is provided in the middle of the frame. The photovoltaic modules enter the transmission mechanism 6 through the input port 51 of the frame. The transfer line drives the busbar self-inspection and heat-pressing mechanism to move to the approximate position where the busbar needs to be heat-pressed. The visual monitoring component 3 of the heat-pressing mechanism identifies and locates the specific heat-pressing position, and then completes the heat-pressing. After completion, the photovoltaic modules are output from the output port 52 of the frame through the transmission mechanism 6. In this invention, the specific identification of the heat-pressing position by the image acquired by the visual monitoring component 3 is obtained by analysis by the main control unit electrically connected to the identification and monitoring component 3. The specific analysis method is not within the protection scope of this invention and will not be described further here.
