Description

Technical Field

[0001] The present invention relates to the technical field of light source plates, and specifically to a feeder backlight source plate. Background Art

[0002] The backlight source plate uses an aluminum alloy material with excellent heat dissipation performance to make the base, and an LED lamp bead panel is inlaid inside, which is combined with a transparent cover plate to make the light source fully irradiate on the structure with a narrow space. It is usually used in the process of moving and positioning the feeder accessories to provide light source irradiation for the upper CCD camera to photograph the position of the accessories, and it is an essential component for feeder detection;

[0003] However, the cover plate of the existing LED light source plate is generally directly installed on the top surface with bolts, resulting in a gap between the cover plate and the base, and it is not completely sealed. Therefore, external air can enter through the gap and come into contact with the LED light source. Moisture and harmful chemical substances in the humid air, such as sulfur dioxide, etc., are likely to react with the LED light source, such as oxidation and sulfidation. Therefore, the LED light source plate lacks protection ability and is vulnerable to erosion by harsh environments, which will lead to a decline in the performance of the LED light source and seriously affect the service life of the LED lamp. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract, and the title of the invention. However, such simplifications or omissions shall not be used to limit the scope of the present invention.

[0023] Secondly, the present invention will be described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the drawings.

[0025] The present invention provides a backlight source board for a feeder. When using this device, first install all the LED lamp beads on the inner cavity bottom surface of the light source board base, then press the sealing strip upward, insert the transparent cover plate into the slot, so that the sealing strip is inserted into the sealing groove, and then push the transparent cover plate completely to the bottom of the slot, so that the sealing strip can seal the gap between the sealing strip and the slot. And under the action of the first spring, the sealing strip presses downward against the transparent cover plate, so that the gap between the bottom of the transparent cover plate and the bottom of the slot is blocked. Then close the closing plate, so that the side baffle presses the lock head and presses the second spring. When the locking hole is coaxial with the lock head, the second spring pops out the lock head into the locking hole to fix the closing plate, so that the side of the slot is also sealed, so as to isolate the external air and avoid the oxidation of the LED lamp beads in contact with the air.

[0026] Figures 1-5 Shown is a schematic diagram of the overall structure of an embodiment of a backlight source board for a feeder according to the present invention. Please refer to Figures 1-5 In this embodiment, a backlight source board for a feeder, its main part includes a mounting component 100 and a closing component 200.

[0027] The mounting component 100 includes a light source board base 110, LED lamp beads 110a uniformly installed on the inner cavity bottom of the light source board base 110, a slot 120 opened on the side wall of the light source board base 110, a transparent cover plate 130 inserted in the slot 120, sealing grooves 140 symmetrically opened on the top surface of the transparent cover plate 130, mounting grooves 150 symmetrically opened on the inner wall of the slot 120 and adapted to the sealing grooves 140, first springs 160 uniformly fixed on the inner wall of the mounting grooves 150, and sealing strips 170 inserted in the mounting grooves 150 and fixed on the first springs 160. The transparent cover plate 130 is a high-transparency acrylic plate;

[0028] The closing component 200 includes a closing plate 210 hinged on the outer wall of the light source board base 110, a side baffle 220 fixed on the outer wall of the closing plate 210, a locking hole 230 opened on the side baffle 220, a circular groove 240 opened on the outer wall of the light source board base 110, a second spring 250 fixed in the circular groove 240, and a lock head 260 inserted in the circular groove 240 and fixed on the second spring 250. The lock head 260 is adapted to the locking hole 230; a telescopic rod 270 is fixed on the inner wall of the circular groove 240, the second spring 250 is sleeved outside the telescopic rod 270, and the rear wall of the lock head 260 is fixed on the telescopic rod 270, so that during the movement of the lock head 260, it will not be skewed with the assistance of the telescopic rod 270;

[0029] Among them, the sealing strip 170 has elasticity. After the sealing strip 170 is inserted into the sealing groove 140, the elasticity of the sealing strip 170 itself causes the sealing strip 170 to squeeze the gap between it and the sealing groove 140, filling the sealing groove 140 and completely blocking the sealing groove 140.

[0030] Furthermore, threaded grooves 130a are symmetrically formed on the side walls of the transparent cover plate 130, and fixing grooves 180 adapted to the threaded grooves 130a are symmetrically formed on the side walls of the light source board base 110. Bolts 190 meshing with the threaded grooves 130a are inserted into the fixing grooves 180. During use, when the transparent cover plate 130 is completely inserted into the bottom of the slot 120, the threaded grooves 130a and the fixing grooves 180 are coaxial. At this time, the bolts 190 are inserted into the bottom of the fixing grooves 180, and then the bolts 190 are rotated into the threaded grooves 130a to fix the transparent cover plate 130 on the light source board base 110.

[0031] Combined Figures 1-5 , the specific use process of a backlight source board of a feeder in this embodiment is as follows: When using this device, first install all the LED lamp beads 110a on the inner cavity bottom surface of the light source board base 110, then press the sealing strip 170 upward, insert the transparent cover plate 130 into the slot 120, so that the sealing strip 170 is inserted into the sealing groove 140, and then completely push the transparent cover plate 130 to the bottom of the slot 120, so that the sealing strip 170 can seal the gap between the sealing strip 170 and the slot 120. And under the action of the first spring 160, the sealing strip 170 presses downward against the transparent cover plate 130 to block the gap between the bottom of the transparent cover plate 130 and the bottom of the slot 120. Then close the closing plate 210, so that the side baffle 220 presses the lock head 260 and presses the second spring 250. When the locking hole 230 and the lock head 260 are coaxial, the second spring 250 pops out the lock head 260 into the locking hole 230 to fix the closing plate 210, so that the side of the slot 120 is also sealed, isolating external air and preventing the LED lamp beads 110a from contacting and oxidizing with air.
