Detailed Description
The following description of a preferred embodiment of the present invention will be made in conjunction with the accompanying drawings. However, the scope of the present invention is not limited to the following embodiments, and all simple equivalent changes and modifications made by the claims and the contents of the specification are still included in the scope of the present invention.
referring to fig. 1-3, for the utility model, a backlight lighting fixture comprises a base 1, a lead screw 2, a lead screw nut and a servo motor are arranged on the base, two ends of the lead screw are erected on the upper side surface of the base, the lead screw nut is sleeved on the lead screw through threads, the servo motor can drive the lead screw to rotate relative to the base, a pair of linear rails 3 are arranged outside two sides of the lead screw, a product placing table 4 is erected on the pair of linear rails, and the lower side surface of the product placing table is fixedly connected with the lead screw nut; the base is located one side of linear track is equipped with sticker benchmark unit 5 outward, and is located the other side of linear track is equipped with sticker dust removal unit 6 outward, is located simultaneously one end of linear track is equipped with sticker pressurization unit 7 outward.
the sticker reference unit comprises an upper air cylinder 51, a lower air cylinder 51 and a pair of sticker references 52 fixedly connected with piston rods of the upper air cylinder and the lower air cylinder; the sticker dust removal unit 6 comprises a front cylinder 61 and a rear cylinder 61 and a dust collector, wherein a suction head 62 of the dust collector is fixed on a piston rod of the front cylinder and the rear cylinder; the sticker pressurizing unit comprises a lifting cylinder 71 and a pressing block 72 fixedly connected with a piston rod of the lifting cylinder; the base is provided with a power supply control box and a master controller, and the master controller controls the servo motor, the upper and lower cylinders, the front and rear cylinders and the lifting cylinder to work.
