[0002] In machine vision systems, it is usually necessary to use a light source to illuminate the product when inspecting its appearance.
[0003] When visually inspecting large-format products such as LCD screens, PCBs, and textiles, standard-length bar lights often fail to meet illumination requirements due to the excessive lateral distance of these products. Therefore, extra-long bar lights are needed to provide uniform illumination. However, since the lengths of different large-format products vary, custom-made extra-long bar lights are required. The need for independent design of different lengths of bar lights leads to excessively high inspection costs. Furthermore, the large size of extra-long bar lights makes transportation difficult, and even partial damage necessitates replacing the entire bar light source, resulting in high maintenance costs.

For two adjacent light-emitting components, the two first magnetic components are magnetically connected to the two second magnetic components respectively.
[0008] Furthermore, the first electrical connector is a spring pin, and the second electrical connector is a pin pad.
[0009] Furthermore, in the first direction, the distance between the end of the pin away from the base and the end face of the first side is greater than the distance between the end of the first electrical connector away from the base and the end face of the first side.

[0025] Please see Figures 1 to 4 This utility model provides a magnetically interlocked splicing strip light source, which includes a light-emitting component 100; multiple light-emitting components 100 are provided; each light-emitting component 100 includes a base 110 and a light-emitting element 140; the base 110 is provided with a receiving groove 111 and a light-emitting port 112; the light-emitting port 112 is located at the bottom end of the base 110 and communicates with the receiving groove 111; the light-emitting element 140 is disposed in the receiving groove 111; the two ends of the base 110 along a first direction are a first side end 120 and a second side end 130, respectively; a pin is provided on the end face of the first side end 120 of the base 110. 121. A first magnetic attractor 122 and a first electrical connector 123; a slot 131, a second magnetic attractor 132 and a second electrical connector 133 are provided on the end face of the second side end 130 of the base body 110; the first electrical connector 123 and the second electrical connector 133 are both electrically connected to the light-emitting component 140; a plurality of light-emitting components 100 are arranged sequentially along a first direction, the first side end 120 of two adjacent light-emitting components 100 abuts against the second side end 130, the pin 121 is provided in the slot 131, the first magnetic attractor 122 and the second magnetic attractor 132 are magnetically connected, and the first electrical connector 123 and the second electrical connector 133 are connected.
[0026] The light-emitting component 100 emits light outward from the light outlet 112 through the light-emitting element 140; multiple light-emitting components 100 are arranged sequentially along a first direction, and in two adjacent light-emitting components 100, the pin 121 of one light-emitting component 100 is inserted into the slot 131 of the other light-emitting component 100, and the first magnetic attraction element 122 of one light-emitting component 100 is attracted to the second magnetic attraction element 132 of another, so that the two adjacent light-emitting components 100 are fixedly connected to each other, improving the stability between adjacent light-emitting components 100; the light-emitting components 100 are connected by a pin 121. Pin 121, slot 131, first magnetic clasp 122 and second magnetic clasp 132 are interconnected, making assembly relatively easy. The number of interconnected light-emitting components 100 can be increased or decreased as needed to adapt to different products with large formats to be tested. Furthermore, when the magnetically interlocked splicing strip light source needs to be transported, the light-emitting components 100 can be disassembled to reduce transportation difficulty. Even if a single light-emitting component 100 is damaged, the damaged light-emitting component 100 can be removed and replaced with a new one, resulting in low maintenance costs.
[0027] Reference Figure 2 and Figure 3 In some embodiments of this utility model, the cross-section of the pin 121 and the cross-section of the slot 131 are the same and both are non-circular surfaces, so as to achieve the effect of preventing mistaken identity and to avoid the pin 121 from rotating relative to the first direction in the slot 131.
[0028] The bases 110 of two adjacent light-emitting components 100 are connected to each other by a pin 121 and a slot 131, so as to connect the two bases 110 and define the position between the two bases 110. The pin 121 abuts against the groove wall of the slot 131, so that there is friction between the pin 121 and the groove wall of the slot 131; wherein, the pin 121 and the slot 131 are interference fit.
[0029] Specifically, the cross-section of the pin 121 and the cross-section of the slot 131 can be a semi-circular surface, a square surface, or other non-circular surfaces.
[0030] Reference Figure 2 and Figure 3 In some embodiments of this utility model, two first magnetic attractors 122 and two second magnetic attractors 132 are provided. The magnetic poles of the two first magnetic attractors 122 are opposite, and the magnetic poles of the two second magnetic attractors 132 are opposite. For two adjacent light-emitting components 100, the two first magnetic attractors 122 are magnetically connected to the two second magnetic attractors 132 respectively.
[0031] By setting two first magnetic clasps 122 and a second magnetic clasps 132, the stability of the connection can be improved, and the loosening of the base 110 of the two light-emitting components 100 can be reduced.
[0032] The two first magnetic components 122 have opposite magnetic poles, and the two second magnetic components 132 have opposite magnetic poles, so as to prevent fooling. If one of the light-emitting components 100 rotates around 180° with the other light-emitting components, the first magnetic component 122 and the second magnetic component 132 will have the same pole.
[0033] Reference Figures 2 to 4 In some embodiments of this utility model, the first electrical connector 123 is a spring pin, and the second electrical connector 133 is a pin pad.
[0034] The spring pin protrudes outside the base 110, and the pin pad is embedded inside the base 110. The first side end 120 and the second side end 130 of two adjacent light-emitting components 100 abut against each other, and the spring pin abuts against the pin pad to achieve an electrical connection.
[0035] Reference Figures 2 to 4 In some embodiments of this utility model, in the first direction, the distance between the end of the pin 121 away from the base 110 and the end face of the first side end 120 is greater than the distance between the end of the first electrical connector 123 away from the base 110 and the end face of the first side end 120. This enables the pin to be inserted into the slot 131 at least partially before the two light-emitting components 100 are connected to each other, so that the first electrical connector 123 can be connected to the second electrical connector 133. This can achieve the effect of pre-positioning the first electrical connector 123 and the second electrical connector 133.
[0036] In some embodiments of this utility model, a power supply component is also included; the light-emitting component 140 includes a light-emitting structure and a circuit board; the light-emitting structure is disposed on the circuit board, and the first electrical connector 123 and the second electrical connector 133 are both electrically connected to the circuit board.
[0037] The first electrical connector 123 of the first light-emitting component 100 located at the head end of the multiple light-emitting components 100, and / or the second electrical connector 133 of the first light-emitting component 100 located at the head end, are connected to the power supply component so that the light-emitting components 140 of the multiple light-emitting components 100 can be electrically connected to each other, and the power supply component supplies power to one of the light-emitting components 140, thus enabling power supply to multiple light-emitting components 140 and reducing the difficulty of power supply.
[0038] Specifically, the power supply component can be connected to the first electrical connector 123 or the second electrical connector 133 to reduce the difficulty of power supply. The power supply component can also be connected to the first electrical connector 123 or the second electrical connector 133 at the same time to improve the stability of power supply.
[0039] In some embodiments of this utility model, a control component is also included; the control component is disposed on the circuit board of one of the multiple light-emitting components 100.
[0040] Since multiple light-emitting components 100 are interconnected through a first electrical connection and a second electrical connection 133, the opening and closing of the light-emitting elements 140 of the multiple light-emitting components 100 can be controlled by a control unit.
[0041] Reference Figure 1 In some embodiments of this utility model, the first direction is set in the same direction as the length direction of the base 110 so that multiple light-emitting components 100 can be assembled together, which can extend the length of the magnetically interlocked splicing strip light source and has good adaptability.
[0042] Reference Figure 2 and Figure 3 In some embodiments of this utility model, there are two of each of the first electrical connector 123 and the second electrical connector 133, and they are symmetrically arranged; for two adjacent light-emitting components 100, the two first electrical connectors 123 are respectively connected to the two second electrical connectors 133.
[0043] The stability of the electrical connection can be improved by setting two first electrical connectors 123 and two second electrical connectors 133.
[0044] Reference Figure 2 and Figure 3 In some embodiments of this utility model, a diffuser plate 200 is also included, which is disposed at the light outlet 112.
[0045] By setting up a diffuser plate 200, the light can be diffused.
[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
