[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A material guiding and screening robot for the production and transportation of stainless steel fasteners is shown, comprising a robot body 1, an upper loading and screening trough 2 is provided at the upper end of the robot body 1, and a first electrically-controlled screening frame 3, a second electrically-controlled screening frame 4 and a third electrically-controlled screening frame 5 are movably installed inside the upper loading and screening trough 2 from top to bottom, the first electrically-controlled screening frame 3, the second electrically-controlled screening frame 4 and the third electrically-controlled screening frame 5 have the same structure and control method, three lateral pull-out openings are provided at the bottom of the side wall of the robot body 1, and bottom collecting bins 6 are slidably installed at the positions corresponding to the lateral pull-out openings inside the robot body 1, and an externally mounted closed cover 7 is installed on the side wall of the robot body 1 at the back of the lateral pull-out opening.

[0032] Working principle: The electric drive wheel at the lower end of the robot body 1 controls the entire equipment to move horizontally to the discharge port of the fastener processing equipment, and then collects the fasteners dropped from the discharge port. At the same time, the first electric-controlled screening frame 3, the second electric-controlled screening frame 4 and the third electric-controlled screening frame 5 of different heights are used to screen the fasteners through large and small sieve holes respectively. Finally, fasteners of different specifications and sizes are collected in different bottom collecting bins 6, and the fasteners after screening are transported by the robot body 1, and then transferred to the next processing step.

[0033] In order to improve the assembly stability, the upper end opening of the upper loading screening trough 2 is provided with a top sinking trough.

[0034] In order to facilitate installation and translational adjustment, a bottom guide rail 8 that cooperates with the first electric-controlled screening frame 3, the second electric-controlled screening frame 4 and the third electric-controlled screening frame 5 is bolted fixed on the inner wall of one side of the upper loading screening trough 2, and an elliptical adjustment groove 9 is opened at the corresponding position of the inner wall on the other side of the upper loading screening trough 2.

[0035] In order to cooperate with reciprocating controlled translation to screen materials, the first electrically controlled screening frame 3, the second electrically controlled screening frame 4 and the third electrically controlled screening frame 5 include an inner adjusting motor 10 fixed on the inner side of the adjusting groove 9, an eccentric shaft disc 11 installed on the adjusting shaft of the inner adjusting motor 10, a control link 12 movably installed on the inner wall of the eccentric shaft disc 11, a translation frame 13 movably connected to the control link 12, and a metal screening plate 14 installed inside the translation frame 13.

[0036] The inner adjustment motor 10 drives the eccentric shaft wheel 11 to rotate, and then the eccentric shaft wheel 11 controls the control connecting rod 12 to operate, and then the control connecting rod 12 is used to perform reciprocating translation adjustment on the translation frame 13.

[0037] In order to cooperate with the lateral material guiding and facilitate the fasteners on the first electric control screening frame 3, the second electric control screening frame 4 and the third electric control screening frame 5 to be respectively introduced into the corresponding bottom material collecting bin 6, an arc-shaped material guiding plate 15 cooperating with the bottom material collecting bin 6 is fixedly assembled on the side wall of the bottom guide rail 8.

[0038] In order to cooperate with the flipping adjustment, the inner arc surface of the arc-shaped material guide plate 15 is movably equipped with an arc-shaped material blocking frame 16 and an inner side adjustment support rod 17 for controlling the coordination of the arc-shaped material blocking frame 16 .

[0039] The inner adjusting strut 17 controls the arc-shaped material blocking frame 16 to flip and adjust by telescoping. When the fasteners are placed on the first electrically-controlled screening frame 3, the second electrically-controlled screening frame 4 or the third electrically-controlled screening frame 5, the inner adjusting strut 17 controls the arc-shaped material blocking frame 16 to flip downward by stretching, thereby preventing the fasteners from detaching from the arc-shaped material guide plate 15 during the screening process. When the screening is completed, the arc-shaped material blocking frame 16 is controlled to flip upward, thereby facilitating the fasteners to slide from the arc-shaped material guide plate 15 to the bottom collection bin 6.

[0040] A pull handle 18 is bolted to the outer side of the bottom material collecting bin 6 .

[0041] In order to facilitate external storage, a lateral limiting frame 19 for placing the external closed cover 7 is welded and fixed on the side wall of the robot body 1.

[0042] The externally mounted closed cover plate 7 can be placed inside the lateral limiting frame 19 after being disassembled, which is convenient for placement.

[0043] In order to control the assembly and separation of the translation frame 13 and the control link 12, a bottom mounting groove 20 with an open lower end is opened on the side wall of the translation frame 13, and a lateral telescopic groove is opened on the inner side of the bottom mounting groove 20. A limit frame 21 that cooperates with the control link 12 is elastically assembled inside the lateral telescopic groove.

[0044] The assembly shaft outside the control link 12 is inserted into the bottom mounting groove 20 from the lower end opening, and then the limit frame 21 is used to close the lower end opening of the bottom mounting groove 20 to ensure the connection state between the control link 12 and the translation frame 13.

[0045] An upper control port connected to the lateral telescopic slot is provided at the upper end of the translation frame 13 , and the lower end opening of the bottom mounting slot 20 can be opened by controlling the translation of the limit frame 21 , so as to facilitate the separation of the translation frame 13 and the control link 12 .

[0046] In order to improve the guiding and supporting properties of the control end, a lateral stabilizing slider 22 is elastically mounted on the side wall of the translation frame 13 , and an inner guiding limit groove 23 matching the lateral stabilizing slider 22 is provided on the side wall of the upper loading screening trough 2 .

[0047] The translation frame 13 is inserted into the inner guide limit groove 23 through the lateral stabilizing slider 22 to ensure stability during reciprocating translation.

[0048] An upper operating port for controlling the extension and retraction of the lateral stabilizing slider 21 is provided on the upper surface of the translation frame 13 .

[0049] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
