[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0025] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] like Figures 1 to 5 As shown, the feeding device for PCB testing of the utility model comprises: a frame 1; a carrier conveying line 2, a carrier fixing mechanism, a feeding mechanism and a transfer mechanism are installed on the frame 1.

[0027] The carrier transport line transports the carrier, and the carrier is fixed by the carrier fixing mechanism. The transfer mechanism places the PCB of the feeding mechanism on the carrier, so as to transport the carrier and load the PCB at the same time.

[0028] The feeding mechanism includes: a lifting plate 3 and a driving mechanism 4 for driving the lifting plate 3 to move up and down. The driving mechanism 4 can be a linear module, a cylinder, etc.

[0029] The transfer mechanism includes a moving module 5, a material picking cylinder 6 fixedly installed on the moving part of the moving module 5, a material picking plate installed on the piston rod of the material picking cylinder 6, and a suction nozzle 7 fixedly installed on the material picking plate; the moving module 5 drives the material picking cylinder 6 to move, and the material picking cylinder 6 drives the material picking plate to rise and fall, so that the suction nozzle 7 on the material picking plate contacts the material to pick up the material.

[0030] The carrier fixing mechanism includes a fixing frame 8, a lifting plate 9 for lifting the carrier and separating it from the carrier transportation line 2, a side thrust cylinder 10 and a rotating positioning frame 11; the rotating positioning frame 11 is rotatably installed on the fixing frame 8, and when the side thrust cylinder 10 pushes the carrier along the flow direction of the carrier transportation line 2, the rotating positioning frame 11 contacts the adjacent side of the carrier; a lifting cylinder for driving the lifting plate 9 is connected to the top, and the lifting cylinder is fixedly installed on the fixing frame 8, and the side thrust cylinder 10 is fixedly installed on the fixing frame 8; the lifting cylinder drives the lifting plate 9 to move upward and separate from the carrier transportation line 2, and the side thrust cylinder 10 pushes the carrier, and at the same time the rotating positioning frame 11 rotates so that the rotating positioning frame 11 contacts the adjacent side of the carrier to complete the positioning.

[0031] It should be noted here that a limit block for rotationally positioning the rotating positioning frame 11 is installed on the lifting plate 9. When the rotating positioning frame 11 contacts the limit block, the rotating positioning frame 11 contacts the adjacent side of the carrier, thereby preventing the carrier from tilting.

[0032] The carrier fixing mechanism also includes an elastic member 12 fixedly mounted on the fixing frame 8. The installation heights of the elastic member 12 are different. Along the flow direction of the carrier transport line 2, the installation height of the elastic member 12 decreases. The elastic member 12 is preferably a nitrogen spring, which plays a role in fixing the carrier. By lowering the height, the carrier can be better fixed.

[0033] The lifting plate 9 is provided with a ball bearing 13 , which is installed in an embedded manner. The ball bearing 13 is provided to facilitate the rolling of the carrier on the lifting plate 9 .

[0034] The carrier fixing mechanism also includes a carrier push-back assembly, which consists of a push-back cylinder 14 fixedly mounted on the fixing frame 8 and a push-back plate 15 mounted on the push-back cylinder 14. The end of the push-back plate 15 is inclined, and the push-back plate 15 pushes back the carrier that has moved excessively to move it to the correct position.

[0035] Working principle:

[0036] The lifting cylinder drives the lifting plate 9 to move upward and away from the carrier transport line 2, and the side push cylinder 10 pushes the carrier. At the same time, the rotating positioning frame 11 rotates, so that the rotating positioning frame 11 contacts the adjacent side of the carrier to complete the positioning; the moving module 5 drives the material picking cylinder 6 to move, and the material picking cylinder 6 drives the material picking plate to rise and fall, so that the suction nozzle 7 on the material picking plate contacts the material to pick up the material.

[0037] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
