Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation, and in particular to a stack welding machine component level detection device and a stack welding machine. Background Art

[0002] With the development of science and technology, more and more attention has been paid to the utilization of energy. The role of photovoltaic power generation technology in life has become more and more prominent. Photovoltaic power generation technology can convert light energy into electrical energy, making full use of the energy of nature.

[0003] During the assembly process of photovoltaic modules, the battery modules need to be welded by a stack welding machine. When the battery modules are welded in the stack welding machine, in actual production, the welding platform and the battery strings on both sides are not level, which leads to hidden cracks in the modules, seriously affecting the process yield.

[0004] At present, when the battery components enter the stitch welding machine for welding, there is a lifting arm on each side of the stitch welding machine to grab the battery string. Then the lifting arms on both sides lift the battery string to the welding position and complete the welding on the welding platform. In this process, due to the different origins of the lifting arm motors on both sides and the influence of factors such as the manufacturing process, although the same lifting arm height parameters are input on site, in fact, the battery strings on both sides are not on the same horizontal plane. The current on-site adjustment method for this problem mainly relies on visually observing the height difference of the battery strings on both sides, and then inputting the adjustment to the upper computer of the stitch welding machine for adjustment. However, there are still errors in naked eye observation, and it is possible to reach the level after multiple debugging, which affects the welding progress. Utility Model Content

[0025] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides a horizontal detection device for stitch welding machine components, which is applied to the stitch welding machine and can be used to detect whether the batteries on the left and right sides of the welding platform 5 are horizontal. The device includes a guide rail 1, a plurality of distance measuring sensors 2 arranged on the guide rail 1, a data processing unit 3 for receiving data from the distance measuring sensors 2, and a display 4 for displaying data.

[0028] Specifically, in this embodiment, the guide rail 1 is disposed transversely on the top of the stitch welding machine and is located directly above the welding platform 5 and the battery placement areas on the left and right sides of the welding platform 5. Optionally, the guide rail 1 can slide forward and backward on the top of the stitch welding machine through a sliding assembly, and the guide rail 1 can also be a retractable structure to adapt to stitch welding machines of various models or sizes.

[0029] A plurality of distance measuring sensors 2 are arranged on the guide rail 1. In order to adapt to various types or sizes of stitch welding machines, as well as different battery sizes, the connection between the plurality of distance measuring sensors 2 and the guide rail 1 is set as a movable connection in this embodiment, for example, a snap-on connection, a sliding connection, a threaded detachable connection, etc. are used to realize the movable connection of the distance measuring sensor 2 on the guide rail 1, and this embodiment does not make any special limitation. At the same time, the distance measuring sensors 2 can be distributed on the guide rail 1 at equal intervals to improve the accuracy of the data. The plurality of distance measuring sensors 2 can be used to measure the distance between the distance measuring sensor 2 and the welding platform 5 below the guide rail 1 or the battery in the battery placement area, and send the data information related to the distance to the data processing unit 3 for processing, and finally the display 4 displays the data.

[0030] In some optional embodiments, the number of the distance measuring sensors 2 may be an even number. For example, if the number of the distance measuring sensors 2 is two, Figure 2 As shown, the two distance measuring sensors 2 can be respectively located above the left battery placement area 6 and the right battery placement area 7, and measure the distance between the distance measuring sensor 2 and the batteries in the left battery placement area 6 and the batteries in the right battery placement area 7. When the distance data measured by the two distance measuring sensors 2 are the same, it can be considered that the batteries placed in the battery placement areas on the left and right sides are in the same horizontal plane, and subsequent welding operations can be performed. When the distance data measured by the two distance measuring sensors 2 are different, it can be considered that the batteries placed in the battery placement areas on the left and right sides are not in the same horizontal plane, and the operator needs to adjust the height parameters of the stitch welding machine. If the number of the distance measuring sensors 2 is four or six or even more, they only need to be evenly arranged on the guide rail 1, and the distance measuring sensors 2 on the left and right sides are guaranteed to be symmetrical to ensure the accuracy of data detection.

[0031] In some optional embodiments, the number of the distance measuring sensors 2 may be an odd number. When the number of the distance measuring sensors 2 is an odd number, for example, the number of the distance measuring sensors 2 is three. Figure 3 As shown, the three distance measuring sensors 2 are respectively the first distance measuring sensor, the second distance measuring sensor and the third distance measuring sensor. Among them, the first distance measuring sensor is located in the middle position of the guide rail 1, and the second distance measuring sensor and the third distance measuring sensor are respectively located on the left and right sides of the first distance measuring sensor 2. The area below the first distance measuring sensor corresponds to the welding platform 5. The area below the second distance measuring sensor corresponds to the left battery placement area 6. The area below the third distance measuring sensor corresponds to the right battery placement area 7. At this time, the first distance measuring sensor can first measure the distance between the welding platform 5. Then the second distance measuring sensor and the third distance measuring sensor simultaneously measure and obtain the distance between the battery in the left battery placement area 6 and the battery in the right battery placement area 7. When the distance data measured by the three distance measuring sensors 2 are the same, it can be considered that the welding platform 5 and the batteries placed in the left and right battery placement areas are in the same horizontal plane, and subsequent welding operations can be performed. When the distance data measured by the three distance measuring sensors 2 are different, it can be considered that the welding platform 5 and the batteries placed in the left and right battery placement areas are not in the same horizontal plane, and the operator needs to adjust the height parameters of the stitch welding machine. If the number of the distance measuring sensors 2 is five, seven or even more, they only need to be evenly arranged on the guide rail 1, and the distance measuring sensors 2 on the left and right sides must be symmetrical to ensure the accuracy of data detection.

[0032] In addition, in this embodiment, the distance measuring sensor 2 is activated to perform horizontal detection when each battery is welded to ensure that each battery can achieve a good welding state.

[0033] In some optional embodiments, the data processing unit 3 can be implemented by a programmable PLC logic controller. It should be noted that this embodiment only proposes a frame structure capable of detecting a horizontal state, and the logic program and algorithm inside the data processing unit 3 can be implemented by existing technology, and this embodiment does not make software improvements thereto.

[0034] In some optional embodiments, the distance measuring sensor 2 can be implemented by an infrared distance measuring sensor 2 or an ultrasonic distance measuring sensor 2. The specific type can be selected according to actual conditions and is not particularly limited in this embodiment.

[0035] Furthermore, in this embodiment, the stack welding machine assembly level detection device is also provided with an alarm 8, which can be fixed on the shell of the stack welding machine. The alarm 8 is electrically connected to the data processing unit 3, and is used to receive the alarm signal sent by the data processing unit 3 and give an alarm.

[0036] Specifically, when the distance data measured by the multiple distance measuring sensors 2 are different, the data processing unit 3 will send an alarm signal to the alarm 8, and the alarm 8 will send an alarm prompt to remind the operator after being triggered. The alarm 8 can be a light alarm 8, a sound alarm 8 or a sound and light alarm 8.

[0037] The horizontal detection device of the stitch welding machine assembly in this embodiment can objectively measure the distance between the distance measuring sensor 2 and the welding platform 5 below and the battery placement area through the distance measuring sensor 2, so that the operator can intuitively perceive whether the welding platform 5 and the battery placement areas on both sides are on the same horizontal plane through the display 4, thereby quickly adjusting the height parameters of the stitch welding machine, and the detection process is more efficient and accurate.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
