In the automated assembly line for ring-shaped RFID chips, these chip shells need to be oriented during loading to facilitate subsequent assembly processes.

[0003] However, existing vibratory feeders cannot meet the requirements for directional arrangement of these shells. Utility Model Content

[0004] The purpose of this invention is to provide a vibratory feeder that can qualitatively arrange the shells of ring-shaped RFID chips during feeding, facilitating subsequent automatic assembly processes.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] This utility model proposes a vibratory feeder with a spiral feeding track, the spiral feeding track including a screening track; the cross-section of the screening track is L-shaped, including a first wall and a second wall, the width of the first wall being smaller than the width of the second wall;

[0007] The second wall has a notch, and a baffle is provided between the bottom edge of the second wall and the bottom edge of the notch. The notch has a first end and a second end. The size of the notch at the first end is smaller than the size of the notch at the second end. A horn is provided above the notch at the first end.

[0008] At least at the location of the gap, the first wall slopes outward and the second wall slopes inward.

[0009] In one embodiment, the notch is a quadrilateral notch, and the bottom of the notch has a first included angle at the first end and a second included angle at the second end, wherein the first included angle is an acute angle and the second included angle is an obtuse angle;

[0010] And / or,

[0011] From the entrance of the screening track to the gap, at least a portion of the screening track gradually twists outward.

[0012] In one embodiment, the spiral feeding track further includes an L-shaped conveying track and a conveying platform, the conveying platform, the conveying track, and the screening track are connected in sequence, the conveying platform is horizontally arranged, the conveying track is provided with a third wall and a fourth wall, the width of the third wall is smaller than the width of the fourth wall, and at least part of the conveying track gradually twists outward relative to the conveying platform.

[0013] In one embodiment, the ratio of the width of the third wall, the width of the first wall, and the thickness of the RFID chip housing is 0.8 to 1.2.

[0014] In one embodiment, the spiral feeding track further includes an L-shaped screening table, which is horizontally arranged. The screening track is connected to the outer side of the screening table, and the outlet of the conveying track is located in the middle of the screening table. The screening table located between the screening track and the conveying track forms a sliding part, which is inclined outward.

[0015] In one embodiment, at the exit of the conveying track, the third wall of the conveying track widens to form a wing that protrudes from the exit of the conveying track and has a sharp corner at the bottom of the front end of the wing.

[0016] In one embodiment, at the outlet of the conveying track, the fourth wall of the conveying track has a cutout, the cutout having a first side and a second side, the angle between the first side and the second side being an obtuse angle, and the second side forming a sharp angle with the bottom edge of the fourth wall.

[0017] In one embodiment, the conveying track is connected to the outer side of the conveying platform, and at least the portion of the conveying platform adjacent to the conveying track is inclined outward.

[0018] In one embodiment, the spiral feeding track further includes a discharge channel, which is connected to the outlet of the screening track. At the outlet of the screening track, the screening track is vertically arranged. Near the outlet of the screening track, a lever is provided on the discharge channel, and the axial direction of the lever is parallel to the outlet extension direction of the screening track.

[0019] In one embodiment, the top of the notch has a fourth included angle adjacent to the first included angle and a third included angle adjacent to the second included angle, and the distance between the vertex of the second included angle and the vertex of the fourth included angle is greater than the diameter of the circular portion of the shell.

[0020] The technical solution provided by this utility model has the following advantages and effects:

[0021] By setting a screening track in the spiral feeding track, and setting notches and baffles on the screening track, the size of the first end of the notch is smaller than the size of the second end, so that when the arched shells facing backward pass through the screening track, they will fall into the material trough of the vibrating plate. At the notch position, the first wall is tilted outward and the second wall is tilted inward, so that the shells are arranged one by one as they pass through the notch, thereby realizing the directional arrangement and conveying of the shells.

[0036] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0037] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0038] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0039] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0040] like Figure 1 As shown, the first end of the housing 100 of the ring RFID chip is an arched portion 110, and the second end is a circular portion 120. The diameter of the arched portion 110 is smaller than the diameter of the circular portion 120.

[0041] With the direction of travel of the material shell 100 as the forward direction, the directional arrangement in this embodiment results in the arched portion 110 of the material shell 100 facing forward. This embodiment improves upon the existing spiral feeding track 200 of the vibratory feeder, such as... Figure 2 As shown, the spiral feeding track 200 conveys the material shells 100 spirally upwards from the bottom of the vibratory feeder. To orient these material shells 100 during feeding, a screening track 210 is provided in the spiral feeding track 200. Material shells 100 with their arched portions 110 facing backwards fall into the material trough of the vibratory feeder when passing through the screening track 210, and then re-enter the spiral feeding track 200. Only material shells 100 with their arched portions 110 facing forwards can pass through the screening track 210 for use by the automated assembly line. The spiral feeding process of the spiral feeding track 200 and the structure of the vibratory feeder are conventional technologies in the field and will not be described in detail here.

[0042] Specifically, such as Figure 3As shown, the screening track 210 in this embodiment has an L-shaped cross-section, including a first wall 211 and a second wall 212. The width of the first wall 211 is smaller than the width of the second wall 212. For ease of description, with the shell 100 placed in a flat position as a reference, the top and bottom walls of the shell 100 are collectively referred to as the planar wall 130, and the annular sidewall of the shell 100 is referred to as the vertical wall 140. When the shell 100 moves on the screening track 210, the vertical wall 140 of the shell 100 abuts against the first wall 211, and the planar wall 130 of the shell 100 abuts against the second wall 212.

[0043] To filter out incorrectly oriented shells 100, a notch can be made in the second wall. A baffle is provided between the bottom edge of the notch and the bottom edge of the second wall, and a horn is provided above the notch. Furthermore, the two ends of the notch have different dimensions. For example, to filter shells 100 with the arched portion 110 facing backward, the dimension of the first end of the notch at the rear is smaller than the dimension of the second end at the front; conversely, to filter shells 100 with the arched portion 110 facing forward, the dimension of the first end of the notch at the rear is larger than the dimension of the second end at the front. By providing the baffle, the horn, and the different dimensions of the first and second ends, it is ensured that only correctly oriented shells 100 can pass through the notch.

[0044] Specifically, in this embodiment, a quadrilateral notch 213 is cut into the second wall 212. The bottom of the notch 213 has a first included angle 2131 and a second included angle 2132, and the top has a third included angle 2133 and a fourth included angle 2134. The second included angle 2132 is located in front of the first included angle 2131. The first included angle 2131 is an acute angle, the second included angle 2132 is an obtuse angle, and the fourth included angle 2134 is an acute angle, forming an angle on the second wall 212. The distance between the vertices of the second included angle 2132 and the fourth included angle 2134 is greater than the diameter of the circular portion 120 of the shell 100, and a baffle 214 is provided between the bottom edge of the second wall 212 and the bottom edge of the notch 213. If the arched portion 110 faces forward, when the shell 100 reaches the notch 213, the arched portion 110 of the shell 100 abuts against the stop bar 214, and part of the circular portion 120 of the shell 100 abuts against the stop bar 214 and part against the corner. At this time, the shell 100 will not fall out of the notch 213. As the shell 100 continues to move forward, the circular portion 120 of the shell 100 disengages from the corner. At this time, the arched portion 110 of the shell 100 abuts against the second wall 212 in front of the second included angle 2132. Furthermore, a portion of the circular portion 120 adjacent to the arched portion 110 also abuts against the second wall 212 in front of the second included angle 2132, preventing the shell 100 from falling out of the notch 213. However, if the arched portion 110 faces backward, since the first included angle 2131 is an acute angle and is located behind the second included angle 2132, when the shell 100 travels to a certain position in the notch 213, the shell 100 will only abut against the stop bar 214. At this time, under the action of gravity, the shell 100 will fall out of the notch 213. Therefore, the directional arrangement of the shell 100 for feeding is achieved.

[0045] To prevent the shells 100 from passing through the gap 213 when they are arranged close together, and the impact of the traveling force on the arched portion 110 causing the shells 100 facing backwards to also pass through the gap 213 smoothly, this embodiment provides two gaps 213 at intervals on the second wall 212, thereby improving the reliability of the directional arrangement of the shells 100 for feeding. Obviously, the specific number of gaps is not limited, and there can be more than two.

[0046] To ensure that multiple shells 100 do not stack up when traveling on the screening track 210, the screening track 210 is configured with inclined walls, at least at the notch 213, such that the first wall 211 slopes outward and the second wall 212 slopes inward. "Outward" and "inward" refer to the exterior or interior of the vibrating disc, respectively. In this embodiment, at the entrance of the screening track 210, the second wall 212 is horizontally positioned, and near the notch 213, it is sloped inward, meaning the end of the second wall 212 facing the vibrating disc is higher than the end facing away from it. At least a portion of the screening track 210 from the entrance 215 to the notch 213 gradually twists outward. By twisting at least part of the screening track 210 from a horizontal state to an outward tilted state, if the material shells 100 are stacked, the screening track 210 is tilted, and the first wall 211 and the second wall 212 can only support one material shell 100, while the other material shells 100 will fall off, ensuring that the material shells 100 are fed one by one.

[0047] In some embodiments, after the screening track 210 is twisted outward, it maintains an inclined shape until the outlet 216 of the screening track 210, which facilitates the processing of the screening track 210. For example... Figure 4 As shown, the outlet 216 of the screening track 210 is located on the discharge platform 220. The discharge platform 220 is horizontally arranged, and the inner end of the discharge platform 220 is connected to the discharge channel 221. At the outlet 216 of the screening track 210, the screening track 210 is vertically arranged. The discharge platform 220 is inclined inward, that is, the height of the end of the discharge platform 220 away from the center of the vibrating plate is greater than the height of the end closer to the center of the vibrating plate, so that the material shell 100 can tilt after traveling to the discharge platform 220, changing from a vertical position to a horizontal position. In order to effectively tilt the material shell 100, a long lever 222 is provided on the discharge platform 220 near the outlet 216 of the screening track 210. The axial direction of the lever 222 is parallel to the extension direction of the outlet 216 of the screening track 210. That is, when the material shell 100 slides out of the outlet 216 of the screening track 210, the bottom of the material shell 100 abuts against the lever 222. Since the discharge platform 220 is tilted inward, the lever 222 tilts the material shell 100 into a horizontal position and slides to the inside of the discharge platform 220.

[0048] Because the material shells 100 can take on various shapes on the spiral feeding track, such as stacked together, one material shell 100 partially resting on another, or two material shells 100 standing side by side, etc., to ensure that the material shells 100 are arranged one by one and that their shape entering the screening track 210 is more in line with expectations, an L-shaped conveyor track 230 and a conveyor table 240 are also provided on the spiral feeding track. For example... Figure 2 and Figure 5As shown, the conveyor platform 240, conveyor track 230, and screening track 210 are connected in sequence. The conveyor platform 240 is horizontally positioned, and the material shell 100 enters the conveyor platform 240 in a horizontal state. The conveyor track 230 has a third wall 231 and a fourth wall 232. The width of the third wall 231 is smaller than the width of the fourth wall 232. The vertical wall 140 of the material shell 100 abuts against the third wall 231, and the horizontal wall 130 of the material shell 100 abuts against the fourth wall 232. Furthermore, at least a portion of the conveyor track 230 gradually twists outward, causing at least a portion of the conveyor track 230 to be inclined, thereby gradually changing the material shell 100 from a horizontal state when entering the conveyor platform 240 to an inclined state. The conveyor track 230 connects to the outer side of the conveyor platform 240, and at least a portion of the conveyor platform 240 adjacent to the conveyor track 230 is inclined outward, allowing the material shell 100 on the conveyor platform 240 to slide to the outside and thus smoothly travel onto the conveyor track 230.

[0049] The purpose of tilting the conveying track 230 and the screening track 210 is to prevent the material shells 100 from stacking or overlapping. Therefore, the width of the third wall 231 and the first wall 211 should not be too wide or too narrow. The ratio between the width of the third wall 231, the width of the first wall 211 and the thickness of the material shells 100 is between 0.8 and 1.2. Preferably, the width of the third wall 231 and the width of the first wall 211 are approximately equal to the thickness of the material shells 100.

[0050] In some embodiments, the conveying track 230 and the screening track 210 are spirally descending tracks, and the height of the conveying track 230 is higher than that of the screening track 210. The material shell 100 can also slide down by gravity while traveling on the conveying track 230 and the screening track 210, making the travel smoother.

[0051] In this embodiment, after the conveying track 230 becomes inclined, the material shell 100 remains in an inclined state until it reaches the outlet 233 of the conveying track 230. The material shell 100 at the inlet 215 of the screening track 210 is horizontal; therefore, an L-shaped screening table 250 is also provided. The screening table 250 is horizontally positioned, and the outlet of the conveying track 230 is located in the middle of the screening table 250. Since the outlet 233 of the conveying track 230 is inclined relative to the screening table 250, when the material shell 100 slides from the outlet 233 of the conveying track 230 to the screening table 250, without the clamping of the third wall 231 and the fourth wall 232, it will lie down, changing from an inclined state to a horizontal state.

[0052] The screening track 210 connects to the outer side of the screening table 250. A sliding part 251 is formed on the screening table 250 between the screening track 210 and the conveying track 230. The sliding part 251 is inclined outward, that is, the height of the end of the sliding part 251 near the center of the vibrating plate is greater than the height of the end away from the center of the vibrating plate. This allows the material shell 100 to automatically slide to the outer side on the sliding part 251 and smoothly enter the screening track 210.

[0053] To allow more of the arched portions 110 of the shells 100 to face forward at the exit of the conveyor track 230, the third wall 231 of the conveyor track 230 widens at the exit 233, extending away from the fourth wall 232 to form a side wing 234. The side wing 234 protrudes beyond the exit 233 of the conveyor track 230, and its front end has a pointed corner 2341. When the shells 100 with the arched portions 110 facing backward slide along the side wing 234, the circular portion 120 is in front. When the pointed corner 2341 abuts against the intersection of the circular portion 120 and the arched portion 110, the center of gravity of the shells 100 protrudes beyond the pointed corner 2341. As the circular portion 120 slides outward, the pointed corner 2341 acts as a fulcrum, causing most of the shells 100 to deflect, changing from having the arched portions 110 facing backward to having the arched portions 110 facing forward. As for the shell 100 with the arched part 110 facing forward, when it slides along the side wing 234, even when the arched part 110 is completely protruding from the sharp corner 2341, the center of gravity of the shell 100 is still within the range of the side wing 234, and the side wing 234 still provides support for the shell 100. Most of the shell 100 is not affected by the sharp corner 2341 and will not deflect.

[0054] To ensure that the material shell 100 becomes horizontal when sliding from the outlet 233 of the conveying track 230 to the screening table 250, this embodiment also cuts the fourth wall 232 of the conveying track 230 at the outlet 233: first longitudinally and then obliquely, forming a cut 235. The cut 235 has a first side 2351 and a second side 2352, the angle between the first side 2351 and the second side 2352 is an obtuse angle, and the second side 2352 forms a sharp angle with the bottom edge of the fourth wall 232. When the material shell 100 slides to the position of the cut 235, part of the material shell 100 overlaps on the screening table 250, and the other part overlaps on the fourth wall 232 behind the sharp angle, preventing the material shell 100 from rolling on the screening table 250. As it continues to move, the other part falls from the sharp angle onto the screening table 250, and the material shell 100 becomes horizontal, with the flat wall 130 abutting against the screening table 250.

[0055] In summary, the vibratory feeder of this embodiment filters out shells whose orientation does not meet expectations through gaps in the screening track, and sets up a conveyor track. The conveyor track twists outward to pre-filter stacked and overlapping shells, arranging them individually. A screening platform is installed at the connection between the screening track and the conveyor track, tilting outward. A side wing with a sharp angle is provided at the exit of the conveyor track to deflect shells with their arched portions facing backward as much as possible, changing them so that their arched portions face forward. This achieves forward-oriented directional feeding of the shells, facilitating subsequent processing steps.
