[0028] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0029] The specific implementation of the present application is further described in detail below with reference to the accompanying drawings and examples.

[0030] like Figure 1 The figure shows a schematic diagram of the structure of a flower basket in the prior art. The flower basket 100 includes a base plate 110, two side plates 120, multiple cross bars 130, and a flower basket rod 140 disposed on the base plate 110. The battery cells 110 are vertically placed on the upper end of the base plate 110, with each end of the base plate 110 connected to a side plate 120. The multiple cross bars 130 are parallel to the base plate 110, with their ends connected to the two side plates 120, respectively, to strengthen the connection. The flower basket rod 140 is used to form multiple placement spaces on the base plate 110, each placement space being used to accommodate at least one battery cell. In the prior art, if a camera is needed to detect the presence of debris, the camera's installation position must be ensured so that the camera's shooting range covers the entire flower basket 100, allowing the debris to be captured. However, due to space limitations, some devices cannot be equipped with cameras. Based on this, the embodiment of the present application is a flower basket fragment detection device for the photovoltaic manufacturing industry, which uses a photoelectric module instead of a camera for fragment detection. The photoelectric module only needs to ensure that its detection light can pass through the fragment position. It can be assembled on the flower basket, so it is basically not restricted by space. This new detection device has the advantages of low cost and easy implementation.

[0031] Specifically, the embodiment of the present application provides a device for detecting flower basket fragments in the photovoltaic manufacturing industry, such as Figure 2 and Figure 3 As shown, the flower basket fragment detection device for the photovoltaic manufacturing industry includes a photoelectric module 200, a controller 300 and an alarm 400; wherein, the photoelectric module 200 includes a light emitter 210 and a light receiver 220, the light emitter 210 is arranged on one side of the flower basket 100, and is used to emit a detection light signal 230, the detection light signal 230 is transmitted through the flower basket 100 and is received by the light receiver 220 to obtain a light intensity signal, the signal output end of the light receiver 220 is connected to the controller 300, so as to feed the light intensity signal obtained by the light receiver 220 to the controller 300, and the signal output end of the controller 300 is connected to the alarm 400, and is used to control the operation of the alarm 400 according to the light intensity signal.

[0032] In this embodiment, the detection light signal 230 emitted by the light transmitter 210 may be transmitted light. For example, in the presence of debris, the transmitted light passes through the debris and is received by the light receiver 220. At this time, the light intensity signal received by the light receiver 220 will decrease compared to when there is no debris. Therefore, a light intensity threshold can be preset. When the light intensity threshold is greater than or equal to the light intensity threshold, it indicates that the detection light signal has not detected the presence of debris, while when the light intensity threshold is less than the light intensity threshold, it indicates that debris is present. Based on the comparison result of the light intensity signal obtained by the light receiver 220 with the light intensity threshold, the controller 300 can control the alarm 400 to operate when the light intensity threshold is less than the light intensity threshold, alerting the staff member that debris is present in the flower basket 100. After receiving the alert, the staff member can remove the debris from the flower basket 100.

[0033] In this embodiment, the controller 300 can be selected as a PLC controller, and its connection with the photoelectric module 200 and the alarm 400 can be wired or wireless. The alarm 400 is installed in a conspicuous position so that the staff can receive the prompt signal of the alarm 400 in time. The alarm 400 is preferably an audible and visual alarm.

[0034] In some embodiments, as Figure 4 As shown, the optoelectronic module 200 also includes a power switch 240. After the optical transmitter 210 and the optical receiver 200 are connected in parallel, they are connected to the power supply 500 through the power switch 240. The signal output end of the controller 300 is connected to the signal input end of the power switch 240 to control the on and off of the power switch 240.

[0035] In this embodiment, the photovoltaic module 200 is not always operational; it typically activates debris detection only after a round of cell picking. Therefore, the power supply circuit for the photovoltaic module 200 is designed by adding a power switch 240 controlled by the controller 300. Depending on the actual picking process, the controller 300 can periodically activate the power switch 240 to activate the optical transmitter 210 and optical receiver 220. For example, the controller 300 can control the power switch 240 to turn on after a round of picking is completed.

[0036] In some embodiments, as Figure 5 As shown, the photovoltaic modules 200 are provided in two numbers, and the two photovoltaic modules 200 are respectively provided corresponding to two opposite corners of the flower basket 100 .

[0037] In this embodiment, please combine Figure 1 As shown, if the size of the debris 600 is larger than the distance between the two basket rods 140, the debris 600 may be present on the two basket rods 140. Therefore, two photovoltaic modules 200 can be installed corresponding to the four corners formed by the bottom plate 111 and the two side plates 130, namely, the first corner a, the second corner b, the third corner c, and the fourth corner d. Here, a and c are opposite corners, and b and d are opposite corners. The height of the two photovoltaic modules 200 should be aligned with the height of the basket rods 140 so that the detection light signals they emit can accurately detect debris 600 present on the topmost bottom plate assembly 110. In this case, both photovoltaic modules 200 are installed outside the basket 100. This is because the space inside the basket 100 is used to store solar cells. Therefore, installation outside the basket 100 allows the photovoltaic modules 200 to perform their detection function without interfering with the normal function of the basket 100.

[0038] In some embodiments, as Figure 6 As shown, the photovoltaic modules 200 are provided in two numbers, wherein one photovoltaic module 200 is provided corresponding to an opposite corner of the flower basket 100 , and the other photovoltaic module 200 is provided corresponding to an opposite border of the flower basket.

[0039] In this embodiment, please combine Figure 1As shown, if the size of the fragment 600 is larger than the distance between the two basket rods 140, the fragment 600 may be present on both basket rods 140. Therefore, one photoelectric module 200 can be positioned corresponding to the two corners formed by the bottom plate 111 and the two side plates 130, namely, the first corner a, the second corner b, the third corner c, and the fourth corner d; where a and c are opposite corners, and b and d are opposite corners. Another photoelectric module 200 is positioned corresponding to the opposite edge of the basket (i.e., on the outside of the two side plates 120). The height of the two photoelectric modules 200 should be aligned with the height of the basket rods 140 so that the detection light signals they emit can accurately detect the fragment 600 present on the topmost bottom plate assembly 110. At this time, the two photovoltaic modules 200 are both installed on the outside of the flower basket 100. This is because the inner space of the flower basket 100 is used to load solar cells. Therefore, installing them on the outside of the flower basket 100 allows the photovoltaic modules 200 to play a detection role without interfering with the normal function of the flower basket 100.

[0040] In some embodiments, for flower basket fragments that are small, i.e., smaller than the distance between two flower basket rods 140, the fragments can be detected by the photoelectric module 200 installed below the bottom plate 110 of the flower basket 100. For example, the photoelectric module 200 installed below the bottom plate 110 of the flower basket 100 can be provided in a plurality, and the layout can be as follows: Figure 7 As shown, to ensure the detection of small debris.

[0041] The above implementation modes are only used to illustrate the present application and are not intended to limit the present application. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions also fall within the scope of the present application, and the scope of patent protection of the present application shall be defined by the claims.
