[0020] Figure 3 It is a structural schematic diagram of embodiment 2 of the present invention. DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0022] Reference Figure 1FIG. 1 is a schematic diagram of a hook screening device according to an embodiment of the present invention. The screening device according to the present invention comprises a material storage box 10, and

[0023] The material taking component 20 is arranged above the material storage box 10 ; the material taking component 20 picks up materials from the material storage box 10 .

[0024] The screening component 30 is arranged below the material taking component 20. The material taking component 20 picks up the material and sends it to the top of the screening component 30, and then sends the material into the screening component 30. The screening component 30 is provided with a screening slot 31. The bottom of the screening slot 31 is a filter slot 32. Both sides of the filter slot 32 are inclined surfaces 33. The material falls into the screening slot 31. Since both sides are inclined surfaces 33, the material falls to the position of the filter slot 32. The hooks with the required posture leak out from the filter slot 32, and the hooks that do not meet the requirements are blocked in the screening slot 31. In order to send the hooks that do not meet the requirements away from the screening slot 31, the first material receiving box 35 is arranged below one end of the screening slot 31, and the push plate 34 is arranged in the other end of the screening slot 31. The push plate 34 matches the inclined surface 33. The push plate 34 is pushed out, and all the materials in the screening slot 31 are pushed out of the screening slot 31, and the materials fall into the first material receiving box 35 below. In order to simplify the structure of the screening device of the present invention and increase the continuous working ability of the device, in this embodiment, the material storage box 10 and the first material receiving box 35 are arranged to overlap, that is, the material storage box 10 and the first material receiving box 35 are the same material box, and the screening component 30 is arranged between the material taking component 20 and the material storage box 10. The material that does not meet the requirements during screening is directly returned to the material storage box 10, reducing the steps of material circulation in the first material receiving box 35 and the material storage box 10, and simplifying the process.

[0025] The first conveying assembly 40, the feeding end of the first conveying assembly 40 is arranged below the filtering slit 32, the discharging end of the first conveying assembly 40 is provided with a first detection sensor, and the discharging end of the first conveying assembly 40 is provided with a second material receiving box 36. During the screening, the hooks meeting the posture requirements leak out from the filtering slit 32 and fall on the first conveying assembly 40, and the first conveying assembly 40 sends the hooks out. When the first detection sensor detects the hooks that do not meet the use requirements, the first conveying assembly 40 continues to convey, and the hooks fall from the discharging end of the first conveying assembly to the second material receiving box 36 for collection, and then screen again. When the first detection sensor detects the hooks that meet the use requirements, the first conveying assembly 40 stops conveying, so that the next station can take them.

[0026] Further, the material taking assembly 20 includes a first horizontal cylinder 21, a first vertical cylinder 22 and a first electromagnet 23, wherein the first vertical cylinder 22 is connected to the first horizontal cylinder 21, and the first electromagnet 23 is installed at the push rod end of the first vertical cylinder 22. In this embodiment, the first horizontal cylinder 21 is arranged above the material storage box 10 and the screening assembly 30 through a bracket, and the first vertical cylinder 22 is pushed by the first horizontal cylinder 21 to move in the horizontal direction, so that the first vertical cylinder 22 moves to the top of the material storage box 10, and then the first vertical cylinder 22 extends downward, driving the first electromagnet 23 to insert into the material storage box 10, and the first electromagnet 23 is reset after adsorbing the hook. The first electromagnet 23 adsorbs 5-10 hooks each time, and since the hooks are piled up when they fall into the screening slot 31, only the hooks below can pass through the filtering slit 32, so it is not suitable to place too many hooks in the screening slot 31 each time. In this embodiment, the electromagnet adsorption method is adopted, on the one hand, the material taking quantity is appropriate and the space occupied is small, and on the other hand, the cost is low.

[0027] Reference Figure 2 As shown, in order to ensure that the hook posture passing through the filter slit 32 is appropriate, that is, the hanging ring and the fixing plate are in an unfolded state, and only one hook can leak onto the first conveying assembly 40 at each position at a time, the width of the filter slit 32 is greater than the thickness of the hook and less than the thickness of the hanging ring and the fixing plate. Therefore, only the hook with an angle of 180° between the hanging ring and the fixing plate can pass through the filter slit 32, and the hooks with other angles between the hanging ring and the fixing plate are blocked in the screening slot 31. Further, the distance between the upper surface of the first conveying assembly 40 and the filter slit 32 is greater than the width of the hook and less than the length of the hook, so only the side hook can pass through the filter slit 32, and a part of the vertical hook is still in the screening slot 31, and then pushed out by the push plate 34. It is ensured that the hooks falling on the first conveying assembly 40 are arranged along the length direction of the filter slit 32 to ensure the consistency of the hook direction. In order to push the push plate 34 to move and push out the remaining materials in the screening tank 31 , the push plate 34 is connected to a push cylinder, and the push cylinder is arranged along the length direction of the filtering slit 32 .

[0028] The first conveying assembly 40 includes a first conveyor belt 41 and a first drive motor 42, and the first drive motor 42 is connected to the first conveyor belt 41 through a transmission wheel. Since the hook is lying on its side when it falls on the conveyor belt, the conveyor belt used in this embodiment can ensure the hook is received and prevent the hook from falling from the gap of the conveying assembly. Furthermore, in order to ensure that the first conveying assembly 40 can carry as many hooks as possible and ensure that the hook falls in the middle of the width direction of the conveyor belt, the first conveying assembly 40 is arranged along the length direction of the filter slit 32. At this time, the position of the hook in the conveying direction of the conveyor belt can be determined to determine the position of the hook, so that the hook can be accurately picked up in the next step.

[0029] Reference Figure 3 As shown, since the hook direction on the first conveyor belt 41 is consistent with the length direction of the filter slot 32, if the hook direction required during installation is perpendicular to the length direction of the filter slot 32, in this case, the screening device also includes a transfer assembly 50, which is used to turn the hook and then output it. The transfer assembly 50 includes a steering assembly and a second conveying assembly 51, and the transfer assembly 50 is arranged above the first conveying assembly 40 and the second conveying assembly 51. The transfer assembly 50 picks up the material on the first conveying device and then turns it and places it on the second conveying assembly 51. Further, in order to realize the turning of the hook, the transfer assembly 50 includes a rotating cylinder 52, and the rotating cylinder 52 is connected to the second horizontal cylinder 53 and the second vertical cylinder 54, and the second electromagnet 55 is connected below the rotating cylinder 52. The second horizontal cylinder 53 and the second vertical cylinder 54 drive the rotating cylinder 52 to go back and forth between the first conveyor belt 41 and the second conveying assembly 51, and the second electromagnet 55 is used to suck up the hook as a whole, and keep the hanging ring and the fixing plate in the same plane, so that the hook is still in the form of the hanging ring and the fixing plate unfolded when it moves to the second transmission assembly 51. To ensure that the next station picks up the hook, a second detection sensor is provided at the discharge end of the second conveying assembly 51. When the second detection sensor detects that a hook has passed, the second conveying assembly 51 stops conveying, and the hook assembly device picks up the hook on the second conveying assembly 51 and installs it on the picture frame, thereby realizing automatic assembly of the hook.
