[0002] In the material handling process of the manufacturing industry, a vibrating feeding hopper transports materials from the storage area to the production line smoothly and continuously. Conventional vibrating feeding hoppers usually have narrower channels in the discharge area, or are equipped with special screening channels. The purpose is to perform preliminary classification and screening of the materials in order to remove those defective products that do not meet the requirements. However, in actual work, although the narrower channels can screen out some larger, irregularly shaped defective products, it is difficult to effectively identify some materials that are close in size to qualified products but have minor defects. Therefore, the screening method of the above structure has the risk of "missed detection". In high-speed flowing materials, some defective products may not be effectively identified and removed by the screening channel due to reasons such as excessive speed or poor position.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] First embodiment

[0029] This embodiment discloses a vibrating feeding hopper 100 assembly, combined with Figure 1For understanding, it includes: a feeding hopper 100, the feeding hopper 100 includes a funnel-shaped shell 110 and a first transport track 120 arranged in the funnel-shaped shell 110, the transport track is spiral, and the end of the first transport track 120 extends to the outside of the funnel-shaped shell 110. The feeding hopper 100 is set on the workbench 600, wherein the feeding hopper 100 includes a driver fixedly set on the workbench 600, and the upper end of the driver is connected to the hopper-shaped shell. In this example, the funnel-shaped shell 110 includes a closed end 111 connected to the driver and an open end 112 extending upward. The specific structure of the first transport track 120 can be referred to Figure 2 for understanding. The upper surface of the first transport track 120 is a sloped surface, and the sloped surface at the starting end of the first transport track 120 smoothly transitions to the bottom surface of the funnel-shaped shell 110. Specifically, the first transport track 120 includes a vertical surface 121 and a horizontal surface 122. The vertical section of the first transport track 120 gradually rises from the starting section, and the horizontal surface 122 extends along the spiral direction. The vertical surface 121 of the upper track is above the horizontal surface 122 of the lower track. In this example, the first transport track 120 is defined as a first spiral layer 123 and a second spiral layer 124. The end of the second spiral layer 124 also extends a lower slope section, and the lower slope section is a slope extending downward. An auxiliary track 700 is provided next to the ramp of the lower slope section, and the auxiliary track 700 extends to the side of the transfer plate 200.

[0030] In this example, the end of the first transport track 120 is directly opposite to the circumferential edge of the transfer tray 200, and the transfer tray 200 is provided with a plurality of clamps 210 at the edge; the other circumferential edge of the transfer tray 200 is directly opposite to the second transport track 500. Figure 1-3 In the structure shown, the clamp 210 is a non-standard clamping part with a clamping mouth. In different situations, the clamp 210 can be processed into different clamping structures, which are not listed here. The vibration feeding hopper 100 assembly also includes a detection assembly 300, which is arranged above the second transport track 500, and one end of the second transport track 500 faces the transfer plate 200. The starting section of the second track is provided with a wedge block 510, and the pointed end of the wedge block 510 faces the edge of the transfer plate 200. After the workpiece portion clamped by the clamp 210 is overlapped on the wedge block 510, it is guided to the second track by the wedge block 510.

[0031] During operation of the vibrating loading hopper 100 assembly, the workpiece clamped by the clamp 210 is first positioned at the circumferential edge of the transfer tray 200. Once the transfer tray 200 is activated, the workpiece is released from the clamp 210 through rotation and moves along the edge of the transfer tray 200 toward the second transport track 500. As the transfer tray 200 rotates, the workpiece gradually approaches the starting end of the second transport track 500.

[0032] When the workpiece reaches the junction of the transfer tray 200 and the second transport track 500, the pointed end of the wedge block 510 guides the workpiece smoothly into the second transport track 500. Because the wedge block 510 is designed to provide guidance, the workpiece can easily slide along the wedge block 510 toward the second transport track 500. The inclined surface design of the wedge block 510 ensures smooth and continuous transfer of the workpiece, reducing potential misalignment or jamming during transfer.

[0033] After entering the second transport track 500, the workpiece continues to advance along the track. In different situations, the second transport track 500 is designed with appropriate inclination and curvature to accommodate workpieces of different shapes and sizes, ensuring that they can stably move to the next processing or assembly station.

[0034] Second embodiment

[0035] Based on the above embodiment, continue to refer to Figure 1-2 It is understood that the transfer plate 200 includes a bottom steering column 220, and a disc 230 extends from the upper end of the bottom steering column 220, and the clamping piece 210 is provided at the edge of the disc 230. The vibrating feeding hopper 100 assembly also includes a feeding channel 400, and a first port 410 and a second port 420 are respectively provided at both ends of the feeding channel 400. The first port 410 is open, and the first port 410 is connected to the second port 420 through the feeding channel 400, and the second port 420 faces the feeding hopper 100. The feeding channel 400 is designed to guide the movement of materials from one area to another during the feeding process. Specifically, the first port 410 is located above the feeding channel 400, allowing raw materials or semi-finished products to enter the channel from above. This structure makes it easy to directly put materials into the channel from a high place or through other mechanical means, and then guide the materials to the second port 420 by gravity or mechanical push.

[0036] The second port 420 is located at the other end of the channel, facing the feeding hopper 100, so that the material transported through the feeding channel 400 can directly enter the feeding hopper 100. This layout optimizes the material conveying path, reduces the scattering and blockage of the material during the transfer process, and improves the feeding efficiency.

[0037] Furthermore, the bottom steering column 220 of the transfer tray 200 not only supports the entire transfer tray 200 but also allows it to be rotated or positioned when necessary. The circular disc 230 supports multiple clamps 210, evenly distributed around the edge of the disc 230, to facilitate the clamping and release of workpieces. The configuration and design of the clamps 210 can be adjusted based on specific work requirements and workpiece characteristics to accommodate diverse operating environments and production needs.

[0038] Furthermore, in some preferred embodiments, the structure of the feeding channel 400 can also be optimized as needed. For example, a guide plate or a rolling bar can be set inside the channel to help guide the material through the channel smoothly and prevent it from being blocked or deviating from the predetermined path during transportation.

[0039] Third embodiment

[0040] Based on the above embodiment, in this example, we continue to refer to Figure 1-2 And combined Figure 3 It is understood that the detection component 300 includes a first detection component 310 and a second detection component 320, and the second detection component 320 is away from the transfer disc 200 relative to the first detection component 310. The first detection component 310 is used to confirm whether the workpiece has correctly arrived at the starting position of the second transport track 500. In a specific example, optical or electronic sensing technology can be used to detect whether the workpiece enters the transport track according to the predetermined path to ensure that each workpiece can accurately enter the track without deviation. The first detection component 310 is used to preliminarily detect surface defects or dimensional discrepancies of the workpiece. Through a preliminary scan of the workpiece, problems that may occur in the production process can be discovered early, so that the workpiece can be eliminated or reflowed for rework before further processing.

[0041] The second inspection assembly 320, located further away from the transport track, is used for final quality inspection after the workpiece has completed all processing steps. The second inspection assembly 320 also collects data to provide real-time feedback for the production process and optimize production parameters. This helps adjust equipment settings, reduce production defects, and improve overall production efficiency.

[0042] Specifically, the first detection component 310 includes a first collecting component 311, a second collecting component 312 and a third collecting component 313; the collecting directions of the first collecting component 311, the second collecting component 312 and the third collecting component 313 converge to the area above the second transport track 500; wherein, the third collecting component 313 is located directly above the second transport track 500.

[0043] In this example, the first acquisition component 311, the second acquisition component 312 and the third acquisition component 313 are all optical sensors, specifically image collectors. The first acquisition component 311, the second acquisition component 312 and the third acquisition component 313 work together to capture images of the workpiece from three different directions, and finally generate a three-dimensional model of the workpiece through data fusion technology.

[0044] The second detection assembly 320 includes a fourth collecting component 321, a fifth collecting component 322 and a sixth collecting component 323; the collecting directions of the fourth collecting component 321, the fifth collecting component 322 and the sixth collecting component 323 converge to the area above the second transport track 500; wherein the fourth collecting component 321, the fifth collecting component 322 and the sixth collecting component 323 are located in the same plane space.

[0045] In this example, the fourth, fifth, and sixth acquisition components 321, 322, and 323 are all image acquisition devices. They are used to monitor the surface conditions of the workpiece in different directions to determine whether they meet requirements. This example is suitable for three-sided machining. In other cases, the number of acquisition components may be determined based on the number of surfaces to be inspected.

[0046] Fourth embodiment

[0047] Based on the above embodiment, a pusher 810 and a collecting channel 800 are further provided beside the second transport track 500, and the pushing direction of the pusher 810 is toward the collecting channel 800. Figure 1-3 In the structure shown, the pusher 810 is a columnar device with a cone structure at the end, and the bottom of the collecting channel 800 is connected to a material receiving bin (not shown in the figure), which is used to receive unqualified workpieces.

[0048] In this embodiment, when a workpiece passes an inspection point on the second transport track 500, the inspection assembly 300, consisting of first, second, and third acquisition components 313, performs a preliminary quality assessment. These acquisition components are high-precision image acquisition devices capable of capturing surface images of the workpiece from multiple angles and generating a three-dimensional model of the workpiece through data fusion technology. This data is analyzed in real time to determine whether the workpiece meets preset quality standards.

[0049] If the workpiece is identified as unqualified, it will be pushed by the pusher 810 to the collection channel 800 next to it. The design of the pusher 810 includes a cone structure that can accurately control the thrust to ensure that only workpieces marked as unqualified are pushed out of the transport track. The action of the pusher 810 is synchronized with the output of the detection component 300 to ensure that there will be no misoperation or omission of unqualified workpieces. The unqualified workpieces pushed out of the track slide along the collection channel 800 and eventually flow into the receiving bin at the bottom. The receiving bin is specially designed to accommodate all screened-out unqualified products, and the capacity of the receiving bin is large enough to cope with accumulation during continuous production. In addition, the design of the receiving bin is convenient for regular emptying and maintenance to ensure the continuous operation and efficiency of the production line.
