[Brief explanation of the drawings]

[0018] Other features, objects and advantages of the invention will become more apparent upon reading the detailed description given below of non-limiting examples with reference to the drawings, in which:

[0019] [Figure 1] 1 is a schematic diagram mainly showing a front view of an LED strip-type digital picking display according to the present invention; FIG. [Figure 2] 1 is a schematic diagram of a circuit board according to the present invention, mainly showing that the circuit board is connected to a multi-core wire through a connector; [Figure 3] 1 is a schematic diagram mainly showing the connection of the LED strip type digital picking indicator according to the present invention; FIG. DETAILED DESCRIPTION OF THE INVENTION

[0020] The present invention will be described in detail below with reference to specific examples. The following examples are intended to help those skilled in the art to better understand the present invention, but are not intended to limit the present invention in any way. Those skilled in the art may make some modifications and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention.

[0021] As shown in Fig. 1, the LED strip-type digital picking display according to the present invention includes a base 1, a cable assembly, a switch 4, a substrate 6, an LED lamp 5, and a cover plate 7. The cable assembly is fixedly attached to the bottom of the base 1, the substrate 6 is fixed inside the cover plate 7, the LED lamp 5 is attached to the substrate 6 facing the cover plate 7, and the switch 4 is provided between the substrate 6 and the cable assembly. The base 1 allows the cover plate 7 to move in the direction of extension and contraction of the switch 4, and the switch 4 turns off the LED lamp 5.

[0022] In this invention, a command is sent from the host computer to the controller, which turns on the LED light at the storage location where work is required. When the sorting work is completed and the light needs to be turned off, the worker presses down on the cover plate 7 with their hand. Because the board 6 is fixed inside the cover plate 7, the board 6 moves downward, and the switch 4 is pressed by the cable assembly (the spring of the switch 4 is attached to one end close to the board 6). The switch 4 is compressed by the force and sends a light-off signal to the host controller, turning off the LED light. After the worker releases their hand, the spring built into the switch 4 returns, causing the switch 4 to move upward, driving the entire board 6 and cover plate 7 to return to their original positions.

[0023] It should be noted that the method of pressing the cover plate 7 is a method of turning off the LED light, and the turning off of the LED light can also be controlled directly by a host controller. The structural design of the present invention is mainly to turn off the light by pressing the cover plate 7, and the method of controlling the turning on or off of the LED light by a host controller is not within the scope of protection of the present invention.

[0024] Specifically, the cable assembly includes a multi-core wire 2 and a protective plate 3. The multi-core wire 2 is disposed in a space defined by the protective plate 3 and the bottom of the base 1, and the protective plate 3 is engaged in a first engaging groove 101 at the bottom of the base 1. In one possible embodiment, the protective plate 3 has an inverted U-shape and is preferably made of PVC. First, the multi-core wire 2 is disposed at the bottom of the base 1, and the inverted U-shaped protective plate 3 is press-fitted into the engaging groove at the bottom of the base 1. The multi-core wire 2, preferably a four-core wire, is accommodated in the space defined by the protective plate 3 and the bottom of the base 1. The protective plate 3 protects the multi-core wire 2 from external forces, while the switch 4 has one end connected to the substrate 6 and the other end in contact with the protective plate 3. The switch 4 is compressed by the pressing force of the protective plate 3.

[0025] In one possible embodiment, as shown in FIG. 2 , the board 6 includes a printed circuit board, and an upper controller supplies signals and power to the board 6 via the multi-core wire 2. The multi-core wire 2 is connected to the board 6 via a connector 8, which includes a male connector and a female connector for easy installation and wiring. The male connector is inserted into the female connector, which is connected to the multi-core wire 2, and the male connector is connected to the board 6, completing the connection between the multi-core wire 2 and the board 6. By connecting the board 6 and the multi-core wire 2 using the connector 8, the connector 8 can be divided into a male connector and a female connector, making it easy to disconnect and connect the connector 8.

[0026] The cover plate 7 of the present invention must be able to allow the LED lamp to radiate heat outward through the cover plate 7 and be able to withstand pressure. Therefore, the cover plate 7 is preferably made of PC material. PC material has high strength and elastic modulus, is not easily deformed when subjected to large external forces, has excellent impact resistance, and is known as "transparent metal" with a light transmittance of over 90%, making it suitable for the production of optical devices and transparent components. PC material also has strong resistance to ultraviolet rays and climate changes, and is not easily discolored or embrittlement.

[0027] The structure of the cover plate 7 must satisfy the following: The base 1 allows the cover plate 7 to move in the extension / contraction direction of the switch 4, and by pressing the cover plate 7, the switch 4 is compressed under force, turning off the LED lamp 5. The structure of the cover plate 7 is designed so that second engaging grooves 701 are formed opposite each other on the inner wall of the cover plate 7, both sides of the substrate 6 are engaged in the second engaging grooves 701, the substrate 6 is fixed inside the cover plate 7, the LED lamp is fixed to the substrate 6, and the LED lamp is housed in the space surrounded by the substrate 6 and cover plate 7 so that it faces the cover plate 7, and when the LED lamp is turned on, the cover plate 7 emits light to the outside. The side wall of the base 1 extends into the base 1 to form a position limiting end 102, and a third engagement groove 702 is provided opposite the outer wall of the cover plate 7, the position limiting end 102 is accommodated in the third engagement groove 702, the switch 4 is compressed by an external force, and the position limiting end 102 allows the third engagement groove 702 to move along the extension / contraction direction of the switch 4, the position limiting end 102 at the upper end of the base 1 is gap-fit ​​with the third engagement groove 702, and the gap between the position limiting end 102 and the third engagement groove 702 allows the cover plate 7 to move downward when pressed, but does not allow the cover plate 7 to move excessively downward, and the position limiting end 102 is a first position limiting structure. The base 1 has two opposing position limiting protrusions 103 on its inner wall. When the switch 4 is compressed by an external force, the position limiting protrusions 103 will not allow the switch 4 to pass through the third engagement groove 702, further preventing the cover plate 7 from moving excessively downward, forming a second position limiting structure. Generally, when the cover plate 7 is pressed, the cover plate 7 will not move downward under the position limiting action of the position limiting ends 102, and the switch 4 will also be compressed by the force, turning off the LED lamp.

[0028] Specifically, as shown in Figure 3, the LED strip digital picking indicator of the present invention further includes sealing heads 9 fixed to both ends of a base 1, with mounting holes 901 formed at the top of the sealing heads 9. The mounting holes 901 are used to fasten the sealing heads 9 to the shelf where the digital picking indicator is required, thereby securing the LED strip digital picking indicator to the shelf. The length of the LED strip digital picking indicator is adjustable, so that if the shelf is narrow, the LED strip digital picking indicator can be shortened to accommodate fewer LED lamps 5, and if the shelf is wide, the LED strip digital picking indicator can be lengthened to accommodate more LED lamps 5. Two or more LED strip digital picking indicators are fixedly connected by a partition block 10, and the leading and trailing ends of the two or more LED strip digital picking indicators are further secured to the shelf by sealing heads 9. The LED strip-type digital picking indicator of the present invention is highly customizable and can meet customer needs for various sizes, formats, storage locations, and usage scenarios.
