[0046] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. For the purpose of simplicity, the components and arrangements of the particular examples are described in the following disclosure. These are, of course, merely examples and are not intended to limit the present application in any way. Furthermore, the present application can be implemented in a variety of environments and / or applications, and the following description is not intended to limit the present application to any particular environment or application. In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize that other processes and / or materials can be used.

[0047] Please refer to Figures 1-11 The present application provides a technical solution: a production feeding equipment for a fresh air purification system assembly and a working method thereof, comprising a feeding port 1, a screening mechanism, an integration mechanism 2, and a feeding channel 3,

[0048] The screening mechanism is arranged at the lower end of the feeding port 1, and the screening mechanism comprises a plurality of single-slot grooves, the width of the single-slot groove is matched with the width of the blade 5, and the lower side of the single-slot groove is provided with a conveying inclined belt 101, which conveys the blade 5 to the upper end;

[0049] The integration mechanism 2 is arranged at the lower side of the conveying inclined belt 101 conveying end, and the integration mechanism 2 comprises an integration limiting frame 201, the inner side of the integration limiting frame 201 is provided with a limiting groove 202, and the limiting groove 202 limits the blade 5 to be in a horizontal standing state;

[0050] The feeding channel 3 is connected with the integration limiting frame 201, the blade 5 is laid flat back to normal and enters the feeding channel 3 after being separated from the limiting groove 202.

[0051] In the current production and manufacturing companies that pursue automated processing, vibrating loading trays and loading robots are often used to achieve the sorting, screening and loading of a large number of parts. However, when it comes to the blade 5 part, the above technologies have some shortcomings, such as Figure 1 As shown, the blades 5 are slender, curved, and thin-sheet structures, which are very easy to hook and stack with each other in the vibrating track, forming a "bird's nest" disorder. During the vibration process, the curved pieces may enter the track at any angle (positive / negative / sideways), which is difficult to reliably correct through baffles or blowing devices; and the blades 5 are in a highly random overlapping state when they are scattered. The robot cannot accurately locate the gripping point of each blade 5 through a conventional visual system, and without a targeted clamping claw design, it is also impossible to stably clamp the blade 5. Therefore, the present application discloses an automatic sorting, screening, and feeding device specifically for the blades 5, which is as follows:

[0052] When screening and loading are first started, a batch of blades 5 are manually put into the feeding port 1. Several blades 5 are restricted in the feeding port 1 and fall into the screening mechanism. Several single-row slots are provided. The width of the single-row slots is not less than the width of the blades 5. Several blades 5 fall into the several single-row slots. The single-row slots restrict and accommodate blades 5 that are adapted to their width. At this time, the several blades 5 in the single-row slots may be in several states, such as vertical or inclined, stacked in multiple layers, or parallel to the single-row slots; then the several blades 5 in the single-row slots are transported upward by the conveyor inclined belt 101. Because it is set to be inclined for transportation, under the action of gravity and the contact friction on both sides of the slot, the several blades 5 in the vertical or stacked state gradually slide in the opposite direction of transportation, leaving the blades 5 attached to the upper side of the conveyor inclined belt 101 and parallel to it, and then a single blade 5 can be screened out for transportation. Several single-row slots and several conveyor inclined belts 101 are provided to realize simultaneous screening of multiple rows, thereby increasing the efficiency and success rate of screening;

[0053] However, even after the above screening mechanism, the screened blades 5 will still be in two states (for example, Figure 1 As shown), an integration mechanism 2 is provided. Specifically, multiple rows of blades 5 are uniformly transported to the integration limit frame 201, and the blades 5 fall into the integration limit frame 201. The blades 5 are restricted to a horizontal upright state (as shown in FIG. 2 ) by the limit groove 202. Figure 4 As shown), the blades 5 are transported to the upper channel 3 in sequence until they are out of the limiting groove 202. Since the curvature of the blades 5 in the horizontally upright state is offset to one side, the blades 5 are tilted and flattened back to the right position under the gravity offset of their own curvature. That is to say, through the integration mechanism 2, the multiple rows of screened blades 5 are finally integrated into the same row, and the blades 5 in the front and back states are finally returned to the same state. Finally, they are transported to the next assembly process by the feeding channel 3, thereby realizing stable screening and feeding of the blades 5.

[0054] The upper end of the limiting groove 202 is provided with a circular arc inclined surface;

[0055] The inner side of the integrated limiting frame 201 is provided with two rows of rotating wheels 205, the upper end of the rotating wheel 205 is provided with an inclined chamfer, and the interval between the two rows of rotating wheels 205 is matched with the overall thickness of the blade 5.

[0056] Preferably, when the plurality of blades 5 are transported into the integrated limiting frame 201, the plurality of blades 5 fall into the limiting groove 202 along the circular arc inclined surface, so that the overall state of the blade 5 gradually changes to the standing state, until falling into the bottom of the limiting groove 202, and finally becoming a horizontal standing state, at the same time, two rows of rotating wheels 205 are arranged at the bottom of the integrated limiting frame 201, the blade 5 falls between the two rows of rotating wheels 205, and the rotating wheel 205 is driven to rotate by the motor, so as to clamp and transport the blade 5 to the feeding channel 3.

[0057] One end of the integrated limiting frame 201 is provided with a discharge port, and the height of the discharge port is matched with the overall width of the single blade 5.

[0058] Preferably, when the blade 5 maintains the horizontal standing state and moves to the discharge port, since the discharge port can only limit the single blade 5 to pass, if there are multiple vertically stacked blades 5, they are limited to remain in the integrated limiting frame 201, that is, the single blade 5 can be screened onto the feeding channel 3, and the blade 5 separated from the discharge port can be returned to normal, completing the screening of the normal and reverse postures;

[0059] Optionally, in order to avoid that the interval between the two rows of rotating wheels 205 is too small and the blade 5 is stuck when falling and cannot fall into the bottom, one of the rotating wheels 205 is provided with a movable wheel frame (such as Figure 11 The wheel frame is driven by a linear driving mechanism, so as to adjust the interval between the two rows of rotating wheels 205, when the interval is sufficient for the blade 5 to fall stably, the wheel frame is displaced so that the two rows of rotating wheels 205 clamp the blade 5, and the other row of rotating wheels 205 is driven to rotate, realizing the transportation of the blade 5. The linear driving mechanism includes but is not limited to a cylinder, a gear and rack mechanism or a lead screw mechanism.

[0060] The screening mechanism further comprises a plurality of rotating rollers 102, the rotating directions of adjacent rotating rollers 102 are opposite, the lower end of the rotating roller 102 is provided with a partition plate 103, the diameter of the rotating roller 102 is the same as the thickness of the partition plate 103, and a single column groove is formed between adjacent partition plates 103.

[0061] Preferably, in order to avoid that the plurality of blades 5 to be screened are stacked and stuck in the feeding port 1, the rotating roller 102 is driven by a motor assembly, and the rotating directions of adjacent rotating rollers 102 are opposite, so that the blade 5 in contact with the rotating roller 102 is continuously subjected to rotating friction, thereby changing its position state until it can fall into the single column groove, thereby increasing the screening efficiency.

[0062] The lower end of the partition 103 is fixedly connected to the supporting inclined bottom plate 104. The two ends of the supporting inclined bottom plate 104 are respectively provided with a first pulley 105, a second pulley 106 and a third pulley 107. The two sides of the supporting inclined bottom plate 104 are provided with an adaptive belt groove, which is equal to the width of the single row groove.

[0063] Tension rollers 108 are staggeredly provided at the lower end of the second pulley 106 .

[0064] Preferably, a first pulley 105, a second pulley 106 and a third pulley 107 are provided to drive the conveyor inclined belt 101 to achieve oblique transport and screening of the blades 5;

[0065] Optionally, a tensioning roller 108 may be provided to tighten the conveyor diagonal belt 101 to ensure the stability of transportation;

[0066] Optional, such as Figure 10 As shown, the pulley can be set as a synchronous pulley and the transmission inclined belt 101 can be set as a synchronous belt to further improve the transmission stability.

[0067] One end of the partition 103 is connected to a grid inclined plate 109, which is fixed to the upper end of the supporting inclined bottom plate 104. A first screening inclined block 4 is provided at the outlet of the single-row trough, and a second screening inclined block 401 is provided on the middle side of the grid inclined plate 109. The spacing between the first screening inclined block 4 and the second screening inclined block 401 is not less than the length of a single blade 5, and the straight-line distance from the second screening inclined block 401 to the conveying inclined belt 101 is not less than the overall thickness of a single blade 5.

[0068] Preferably, in order to further improve the accuracy of screening and avoid multiple layers of stacked blades 5 from being unable to be screened out, a first screening inclined block 4 is provided. Specifically, if the overall height of the blade 5 in the position state is greater than the straight-line distance from the first screening inclined block 4 to the conveyor inclined belt 101, it will be restricted by the first screening inclined block 4 and cannot pass through. In other words, the blades 5 in the oblique transport are further restricted so that only the blades 5 with a stacking height less than the first screening inclined block 4 can pass through. The blades 5 that cannot pass through fall back onto the conveyor inclined belt 101 for re-screening.

[0069] Preferably, a second screening bevel 401 is also provided similarly to further limit the stacking height of the blades 5 , so that only a single layer of blades 5 can pass through, thereby completing a single screening task.

[0070] The integrating mechanism 2 further includes a sliding slope 204 . The sliding slope 204 is disposed at the lower side of the end of the conveying inclined belt 101 .

[0071] Preferably, when the leaves 5 complete the screening work and are transported to the end of the conveying inclined belt 101, a plurality of leaves 5 then fall onto the sliding slope 204, so that the plurality of leaves 5 slide into the integrated limiting frame 201, and a vibration motor can be further arranged in the sliding slope 204, thereby improving the sliding efficiency of the leaves 5.

[0072] One end of the grid inclined plate 109 is connected with a grid straight plate 110, and the third pulley 107 is rotationally connected between adjacent grid straight plates 110, and adjacent third pulleys 107 are arranged staggered and spaced apart by a distance not less than the length of the leaf 5.

[0073] The upper side of the sliding slope 204 is provided with a plurality of discharging square frames 203, the upper end of the discharging square frame 203 is connected with the grid straight plate 110, adjacent discharging square frames 203 are arranged staggered, and the lower end surface of the discharging square frame 203 is adapted to the slope of the sliding slope 204 and has a distance difference.

[0074] Optionally, since a plurality of leaves 5 are simultaneously dropped from the conveying inclined belt 101, in order to avoid the plurality of leaves 5 being too close to each other and thus being stacked, causing the plurality of leaves 5 to be stuck in the integrated limiting frame 201 and unable to smoothly fall, the adjacent third pulleys 107 are arranged staggered (as shown in Figure 9 , so that the lengths of the ends of the adjacent conveying inclined belts 101 are different, so that the adjacent leaves 5 transported are dispersedly dropped into the corresponding discharging square frames 203, avoiding interference between each other, and maintaining a proper distance to enter the integrated limiting frame 201 in sequence and in order.

[0075] A plurality of grid straight plates 110 are fixedly connected with upper stop blocks 111.

[0076] Preferably, in order to improve the stability of the overall posture of the leaf 5 when falling, the upper stop block 111 is arranged, and specifically, when the head end of the leaf 5 moves out of the end of the conveying inclined belt 101, the whole leaf 5 is inclined due to gravity, and at this time the upper stop block 111 limits the rear end of the leaf 5, avoiding excessive inclination of the whole leaf 5, so as to maintain the falling posture of the leaf 5 as stable as possible.
