[0002] Vibration plates are widely used in industrial automation production lines, primarily for automated sorting, directional conveying, and alignment of materials. In particular, in the electronic component manufacturing sector, they efficiently and quickly arrange small parts such as inductors, sensors, and resistors, improving production efficiency, reducing manual intervention, and lowering production costs. In recent years, the trend toward miniaturization and sophistication of electronic products has placed higher demands on the functionality and performance of vibration plates, particularly in terms of multi-position adjustment.

[0004] Related art feeding devices typically include a feeding rack, a vibrating plate, a hopper, and guide rails, feeding components through vibration and guide rail guidance. However, these devices have limitations in adjusting the position of parts. For example, they cannot accurately flip parts from a vertical position to a horizontal position, or smoothly transition between different positions, reducing the overall operating efficiency of the equipment. Summary of the Invention

[0005] In order to overcome the limitations of existing feeding devices in part posture adjustment, improve the accuracy and stability of part feeding, and ensure the smooth progress of subsequent processing, the present application provides a multi-posture adjustment vibration plate.

[0006] The multi-posture adjustment vibration plate provided in this application adopts the following technical solution:

[0007] A multi-posture adjustment vibration plate comprises a top plate, the top plate is provided with a material holding cavity for holding parts, the inner side wall of the top plate is provided with a spiral feeding channel, the feeding channel is provided with a limited turning device, a first stepped turning device, a second stepped turning device, a trough conveying device, a vertical turning device, a horizontal and vertical screening device and a spiral turning feeding trough in sequence along the feeding direction; the limited turning device is used to turn the parts in the vertical state into a lying state, the first stepped turning device is used to turn the parts in the lying state into a horizontal state and convey them to the second stepped turning device, the second stepped turning device is used to convey the parts to the trough conveying device, the trough conveying device is used to convey the parts to the vertical turning device, the vertical turning device is used to turn the parts in the vertical state into a horizontal state, the horizontal and vertical screening device is used to screen and adjust the parts to the required vertical state, and the spiral turning feeding trough is used to adjust the sensor in the vertical state to a lying state.

[0008] By implementing these technical solutions, precise adjustment and transfer of parts in multiple postures is achieved. Specifically, the limited flipping device effectively flips parts from a vertical position to a horizontal position, ensuring that the parts maintain the correct initial posture during subsequent transfer. The first-step flipping device gradually reduces the width of the trough bottom, allowing parts from a horizontal position to flip to a horizontal position under their own weight, improving the accuracy of part posture transitions. The second-step flipping device further optimizes the part transfer path, transferring parts from a horizontal position to the trough conveyor, ensuring continuous and stable transfer. The trough conveyor, using a combination of a first inclined feed trough and a vertical feed trough, gradually adjusts parts from an inclined position to a horizontal position, enhancing the smooth transition between different postures. The vertical flipping device, using a support block structure of varying heights, enables flipping parts from a vertical position to a horizontal position, ensuring consistent posture at all workstations. The horizontal and vertical screening devices screen and adjust parts according to their different postures, ensuring that only parts that meet the requirements enter the next process, improving quality control throughout the production process. The spiral flip feed chute uses a spiral torsion groove to adjust the parts in a vertical state to a flat state, ensuring that the parts reach the required state before final discharge, thereby improving the overall working efficiency of the equipment.

[0009] Optionally, a first posture guide groove is further provided at the starting position of the feeding channel, the depth and width of the first posture guide groove gradually decrease along the feeding direction, and is used to preliminarily guide the posture of the part, and the maximum width of the first posture guide groove is smaller than the width of the part.

[0010] By adopting the above technical solution, since the maximum width of the first posture guide groove is smaller than the width of the part, when the part located at the starting position is in a lying state and is conveyed forward, the first posture guide groove will not affect the normal conveying of the part in the lying state; when the part located at the starting position is in a horizontal or vertical state and is conveyed forward, its posture can be gradually guided when the part initially enters the feeding channel, making it more stable during the conveying process, and at the same time, the posture of the part is adjusted to a posture that is more conducive to subsequent flipping and conveying, reducing the jamming or falling off caused by unstable posture, and improving the overall conveying efficiency and reliability.

[0011] Optionally, the first stepped flipping device includes a first top feed trough and a first bottom feed trough in a stepped shape, and the width of the bottom of the first top feed trough gradually decreases along the conveying direction; the first top feed trough is used to convey sensors in a lying state, and the first bottom feed trough is used to convey sensors in a horizontal state.

[0012] By adopting the above technical solution, the bottom width of the first top feed trough gradually decreases along the conveying direction, so that the part gradually adjusts its center of gravity during the conveying process. When the center of gravity moves above the first bottom feed trough, with the help of gravity, the part naturally flips 90° from a lying state to a horizontal state, ensuring the posture stability and consistency of the part during subsequent transmission.

[0013] Optionally, the second stepped turning device includes a second top feed trough and a second bottom feed trough in a stepped shape, wherein the second top feed trough is used to convey parts in a horizontal state, and the second bottom feed trough is used to convey parts in a lying state.

[0014] By adopting the above technical solution, the second stepped turning device can simultaneously convey parts in a lying state or a horizontal state and smoothly convey them to the subsequent feeding device. Specifically, the second top feeding trough is used to convey parts in a horizontal state, and the second bottom feeding trough is used to convey parts in a lying state.

[0015] Optionally, a first detection air blowing device is also provided on the top plate, and the first detection air blowing device includes a detection mechanism and a blowing mechanism. The detection mechanism is used to detect the orientation of the parts, and the blowing mechanism is used to blow parts with incorrect orientation from the second top feed trough to the second bottom feed trough.

[0016] By adopting this technical solution, the first detection and blowing device can detect the orientation of parts in real time during the transfer process. It then uses the blowing mechanism to blow incorrectly oriented parts from the second top feed trough to the second bottom feed trough, ensuring that the parts always maintain the correct orientation when entering the subsequent processing steps. This not only improves the transfer accuracy of parts, but also effectively reduces the defective product rate caused by incorrect orientation, thereby improving production efficiency and product quality.

[0017] Optionally, a mounting block is provided on the top plate, and the detection mechanism and the blowing mechanism are both provided on the mounting block; a lifting avoidance groove extending vertically is provided on the mounting block, and the detection mechanism passes through the lifting avoidance groove to facilitate the detection of parts in the top plate, and the height of the detection mechanism can be adjusted in the vertical direction.

[0018] By adopting this technical solution, the vertically extending lifting and lowering grooves on the mounting block allow the height of the detection mechanism to be flexibly adjusted vertically. This allows the detection mechanism to adapt to parts of different sizes or types as needed, ensuring accurate and reliable detection. Furthermore, the detection mechanism directly inspects parts within the top plate through the lifting and lowering grooves, improving the directness and efficiency of detection. An air blowing mechanism is also located on the mounting block, facilitating collaboration with the detection mechanism to precisely control and adjust part orientation. This not only enhances the adaptability and flexibility of the equipment, but also further improves the accuracy and efficiency of part transfer and processing.

[0019] Optionally, the trough conveying device includes a first inclined feed trough and a vertical feed trough that are interconnected, the first inclined feed trough is opened on the surface of the feeding channel, and the first inclined feed trough is inclined, and is used to gradually adjust the parts from a lying state or a horizontal state to an inclined state; the vertical feed trough is opened in the first inclined feed trough, and is used to adjust the parts from an inclined state to a horizontal state.

[0020] By adopting the above-mentioned technical solution, the combination of the first inclined feed trough and the vertical feed trough in the trough conveyor system allows for gradual adjustment of the part's posture during conveyance. Specifically, the first inclined feed trough gradually transitions the part from a flat or horizontal position to an inclined position. This step effectively reduces instability during conveyance and improves conveyance stability. Subsequently, the vertical feed trough further adjusts the part from the inclined position to a horizontal position, ensuring that the part's posture and position meet established standards when it enters subsequent processing or assembly, thereby improving overall production efficiency and product quality.

[0021] Optionally, the vertical flipping device includes a guide seat, on which a high-position bearing platform and a low-position bearing platform are fixedly provided in a stepped manner, and the height of the upper surface of the high-position bearing platform is greater than the height of the upper surface of the low-position bearing platform.

[0022] By adopting this technical solution, the parts can fully utilize the stepped structure of the guide seat during vertical flipping, achieving precise posture transitions. In particular, when a part slides from the high-level platform to the low-level platform, the height difference causes the part to naturally flip 90°, adjusting it from a vertical to a horizontal position. This not only improves the reliability of part flipping, but also reduces reliance on external power, simplifies the equipment structure, and reduces energy consumption. Furthermore, the inner sidewall of the guide seat effectively prevents the part from shaking or tilting during flipping, ensuring stability and accuracy throughout the entire transfer process.

[0023] Optionally, a second detection air blowing device is also provided on the top plate, and the second detection air blowing device is set at a certain position of the feeding channel, for detecting the posture of the parts passing through this position, and blowing the parts with incorrect posture to the correct feeding path or readjusting the posture through the blowing mechanism according to the detection results, to ensure that all parts can maintain the correct posture during the feeding process.

[0024] By adopting this technical solution, the second detection air blowing device can monitor the posture of parts during the feeding process in real time, ensuring that each part maintains the correct posture. Specifically, when a part passes the position of the second detection air blowing device, the detection mechanism detects the part's orientation. If the part's orientation is incorrect, the air blowing mechanism immediately activates, using airflow to blow the part from its current path to the correct feeding path or readjust its posture. This prevents jamming or damage caused by incorrect posture, improving production efficiency and product quality.

[0025] Optionally, a posture adjustment and retransmission section is provided on the feeding channel, and the posture adjustment and retransmission section is located between the limit flipping device and the first stepped flipping device. A second posture guide groove is provided on the surface of the posture adjustment and retransmission section for guiding the posture of the part.

[0026] By adopting the above technical solution, the stability and continuity of the parts during the flipping process have been significantly improved. After the parts are initially flipped through the limit flipping device, they may not be able to directly enter the subsequent processing flow due to poor posture. At this time, the posture adjustment and retransmission section plays a key role. The posture adjustment and retransmission section is located between the limit flipping device and the first step flipping device, providing a buffer area for posture adjustment of the parts. The second posture guide groove opened on its surface can further guide the parts to gradually adjust to the optimal posture during the transmission process. In this way, even if the posture of the parts is not good after the initial flipping, it can be effectively corrected in the posture adjustment and retransmission section, thereby ensuring the smooth progress of subsequent processing and avoiding problems such as falling or deviation from the predetermined path due to unstable posture or external force interference.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through the limit turning device, the first step turning device and the second step turning device, the parts can be effectively turned from the vertical state to the horizontal state, and then gradually adjusted from the horizontal state to the required horizontal state and vertical state, ensuring the stability and consistency of the posture of the parts during the entire transmission process, and avoiding transmission failure or damage caused by improper posture adjustment;

[0029] 2. The introduction of the first and second detection air blowing devices enables real-time detection of part orientation during transfer. The air blowing mechanism promptly corrects parts with incorrect orientation, ensuring that all parts maintain the correct orientation before entering subsequent processing, thereby improving production reliability and yield.

[0030] 3. The trough conveying device and the vertical turning device are designed. Through the reasonable layout of the first inclined feeding trough and the vertical feeding trough, and the configuration of high-position and low-position loading platforms at different heights on the guide seat, a smooth transition of parts from a lying state to an inclined state and then to a horizontal state is achieved, which improves the stability and continuity of the transmission and reduces the risk of jamming and blockage.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-3 This application is described in further detail.

[0037] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are simply used to distinguish different components.

[0038] In this embodiment, since the component is in the shape of a rectangular parallelepiped, for ease of understanding, taking a rectangular parallelepiped inductor as an example, the three sides of the component are defined as length, width, and height, respectively; where the length is greater than the width and greater than the height, and the three different placement states of the component are defined as a flat state, a horizontal state, and a vertical state, respectively.

[0039] Lying state: In this state, the length and width directions of the part are both on the horizontal plane, while the height direction is perpendicular to the horizontal plane. In short, the part is in a lying state, and its bottom surface remains parallel to the horizontal plane.

[0040] Horizontal state (length along the horizontal direction): In this state, the length direction of the part (i.e., the long side of the cuboid) remains horizontal, while the width direction is perpendicular to the horizontal plane. Therefore, the part presents a "horizontal standing" posture, and its length direction does not become vertical as it stands.

[0041] Vertical position (length along the vertical direction): In this position, the length of the part has become vertical, that is, perpendicular to the ground. The width direction remains parallel to the horizontal plane. Therefore, the part presents a "vertical standing" posture.

[0042] The embodiment of the present application discloses a multi-posture adjustment vibration plate. Figure 1 The multi-posture adjustment vibrating plate includes a top plate 1, which is provided with a material holding cavity 101 for holding parts. The inner wall of the top plate 1 is provided with a spiral feeding channel 102. The feeding channel 102 is provided with a first posture guide groove 2, a position limiting and turning device 3, a first step-type turning device 4, a second step-type turning device 5, a first detection and blowing device 6, a trough conveying device 7, a vertical turning device 8, a third step-type turning device 9, a second detection and blowing device 10, a horizontal and vertical screening device 11, a spiral turning feeding trough 12 and a discharge limit device 13 in sequence along the feeding direction.

[0043] Reference Figure 1 The depth of the first posture guide groove 2 gradually decreases along the conveying direction of the feed channel 102, and its width also gradually decreases along the feed direction of the feed channel 102. When the part is in a flat position, that is, the length and width of the part are both horizontal and the height is perpendicular to the horizontal plane, the part can be smoothly conveyed forward on the surface of the feed channel 102, and the presence of the first posture guide groove 2 does not significantly affect the part's conveyance. However, when the part is in a horizontal or vertical position, that is, the height of the part is perpendicular to the horizontal plane, but the length or width has a different relationship to the horizontal plane, the first posture guide groove 2 plays a key role. In these two vertical positions, the part is conveyed forward within the first posture guide groove 2. Because the depth and width of the groove gradually decrease along the feed direction, it helps the part gradually adjust its posture during conveyance, allowing it to move more stably along the feed channel 102 and prepare for subsequent directional adjustment and flipping operations.

[0044] Continue to refer to Figure 1The limit flip device 3 includes two limit flip members 31, and both limit flip members 31 are fixed to the inner wall of the top plate 1. The distance between each limit flip member 31 and the surface of the feeding channel 102 is defined as the limit flip spacing. When the parts are in a lying state, the height of the parts is lower than the limit flip spacing, so they can easily pass through the spacing and continue to be transported downward. However, for parts in a horizontal or vertical state, since their height exceeds the limit flip spacing, when they contact the limit flip member 31 during the transmission process, they will be blocked and flipped. Under the guidance of the limit flip member 31, these parts in the vertical state will be flipped 90°, thereby turning into a lying state. Subsequently, these parts that have been flipped into a lying state can continue to be transported downward smoothly from the limit flip spacing.

[0045] Continue to refer to Figure 1 Furthermore, the device is highly adjustable. Two first adjustment slots 103 are defined along the inner sidewall of the top plate 1. These slots 103 have open tops, facilitating installation and adjustment. One end of the position-limiting flip member 31 can be inserted into the first adjustment slot 103 and secured with a bolt, screw, or fixed pin. This allows for flexible vertical adjustment of the position-limiting flip member 31, adapting to the transport requirements of parts of varying thicknesses.

[0046] Continue to refer to Figure 1 The first stepped turning device 4 is used to turn parts in a horizontal position. Specifically, the first stepped turning device 4 includes a first top feed trough 41 and a first bottom feed trough 42, each of which is stepped. The width of the bottom of the first top feed trough 41 gradually decreases along the conveying direction. After passing through the position-limiting turning device 3, parts in a horizontal position are conveyed into the first top feed trough 41. As the parts are conveyed within the first top feed trough 41, the width of the bottom of the trough gradually decreases, causing the center of gravity of the parts to gradually shift toward the first bottom feed trough 42.

[0047] Continue to refer to Figure 1 When the center of gravity of the part moves above the first bottom feeding trough 42, the part will naturally rotate 90 degrees due to its own gravity, changing from a flat position to a horizontal position, and fall into the first bottom feeding trough 42 for further transportation. The bottom of the first bottom feeding trough 42 is tilted, which ensures that the part can be stably transported to the subsequent air blowing and turning correction device in the first bottom feeding trough 42 without falling to the bottom of the material holding chamber 101 due to shaking or tilting.

[0048] Continue to refer to Figure 1The second stepped turning device 5 includes a second top feeding trough 51 and a second bottom feeding trough 52 in a stepped shape, wherein the second top feeding trough 51 is used to convey parts in a horizontal state, and the second bottom feeding trough 52 is used to convey parts in a lying state.

[0049] Reference Figure 1 and Figure 2 , the first detection air blowing device 6 is installed on the top plate 1, and the first detection air blowing device 6 includes a detection mechanism 61 and an air blowing mechanism 62. In order to realize these functions, a first mounting groove 104 is provided on the top plate 1, and a mounting block 63 is fixed inside the first mounting groove 104. The detection mechanism 61 and the air blowing mechanism 62 are both arranged on this mounting block 63. A lifting avoidance groove 64 extending vertically is provided on the mounting block 63. The detection mechanism 61 passes through the lifting avoidance groove 64 to facilitate the detection of parts in the top plate 1, and the detection mechanism 61 also has a second adjustment groove 65 extending vertically. A bolt is passed through the second adjustment groove 65. The bolt is tightly fitted with the mounting block 63 through a thread, so that the height of the detection mechanism 61 can be adjusted as needed.

[0050] Continue to refer to Figure 1 and Figure 2 When a part is in a horizontal position and moves forward within the second top feed chute 51, it first passes through the detection mechanism 61 to determine whether the part is oriented correctly. If the part's orientation meets the preset requirements, the blowing mechanism 62 remains silent, and the part continues to move forward along the second top feed chute 51, eventually reaching the chute conveyor 7.

[0051] Reference Figure 2 and Figure 3 However, if the inspection mechanism 61 detects that the part is oriented incorrectly (i.e., the side with the metal components facing the inspection mechanism 61), the air blowing mechanism 62 will quickly activate. It will use the force of the airflow to blow the part from the second top feed chute 51 to the second bottom feed chute 52, simultaneously flipping the part 90° in the process. The flipped part will continue to move within the second bottom feed chute 52 until it reaches the chute conveyor 7. This ensures that when the parts enter the chute conveyor 7, their surfaces facing the center of the material chamber 101 are all aligned, thus meeting the requirements of subsequent processing or assembly.

[0052] Reference Figure 3 The trough conveyor 7 includes a first, inclined trough 71 and a vertical trough 72, which are interconnected. The first, inclined trough 71 is located on the surface of the feed channel 102 and is inclined, with an arc-shaped inner wall. It is worth noting that the second top trough 51 and the second bottom trough 52 are both used to convey qualified parts to the first, inclined trough 71.

[0053] Continue to refer to Figure 3 Vertical feed trough 72 is located within first inclined feed trough 71, and its bottom is also tilted to ensure stability and continuity during part delivery. After completing the inspection process in first inspection air blower 6, parts are fed one by one through spiral feed channel 102 into first inclined feed trough 71. During this process, the parts gradually transition from their initial horizontal position to an inclined position to accommodate subsequent processing requirements.

[0054] Continue to refer to Figure 3 As parts continue to travel through the first inclined feed trough 71, they eventually enter the vertical feed trough 72. At this stage, the parts' position changes again, from an inclined state to a horizontal state. This continuous posture adjustment process ensures that the parts' posture and position meet established standards and requirements when they enter subsequent processing or assembly, greatly improving overall production efficiency and product quality.

[0055] Continue to refer to Figure 3 The vertical flipping device 8 includes a guide seat 81, and a second mounting groove 106 is provided at a corresponding position of the top plate 1, and the guide seat 81 is fixed in the second mounting groove 106. The inner side wall of the guide seat 81 is integrally formed with a high-level bearing platform 82 and a low-level bearing platform 83 distributed in a stepped manner. The height of the upper surface of the high-level bearing platform 82 is greater than the height of the upper surface of the low-level bearing platform 83. When the part in a horizontal state is conveyed on the high-level bearing platform 82, its length direction extends in the horizontal direction. As the part slides smoothly from the high-level upper surface of the high-level bearing platform 82 to the low-level surface of the low-level bearing platform 83, the part continues to maintain its length direction in the horizontal direction unchanged, but has completed a smooth transition from one height to another.

[0056] Continue to refer to Figure 3 However, when a part in a vertical position is transferred to the upper platform 82, the situation is different. Due to the significant height difference between the upper platform 82 and the lower platform 83, the part is induced by gravity to rotate as it slides from the upper surface of the upper platform 82 to the lower surface of the lower platform 83. Specifically, the part rotates 90 degrees around its axis, thus flipping from a vertical position to a horizontal position.

[0057] Continue to refer to Figure 3 It is worth noting that during the entire transfer process, whether the part is on top of the high-position loading platform 82 or the low-position loading platform 83, its side wall will tightly abut against the inner side wall of the guide seat 81. This not only ensures the stability of the part during transfer, but also prevents it from shaking or tilting during the flipping process.

[0058] Continue to refer to Figure 3 The third stepped turning device 9 comprises a stepped third top feed chute 91 and a third bottom feed chute 92. The height difference provides the necessary space for part turning. The second detection air blow device 10 shares the same structure and function as the first detection air blow device 6, both capable of detecting part orientation and activating the air blow mechanism 62 accordingly. As parts are conveyed forward within the third top feed chute 91, the second detection air blow device 10 first identifies their orientation. If the part's orientation is correct, the second detection air blow device 10 will not activate, and the part will continue to be conveyed forward within the third top feed chute 91 until it reaches the horizontal and vertical screening device 11.

[0059] Continue to refer to Figure 3 However, if the second detection air blowing device 10 detects that the part is not oriented correctly (i.e., the side of the part with the metal component is facing the second detection air blowing device 10), the blowing mechanism 62 is immediately activated. The second detection air blowing device 10 uses precise airflow control to blow the part from the third top feed chute 91 to the third bottom feed chute 92, flipping the part during the blowing process to correct its orientation.

[0060] Continue to refer to Figure 3 It is worth noting that in order to ensure that the parts can continue to be conveyed stably after flipping, a posture adjustment and retransmission section 14 is provided on the feeding channel 102. The posture adjustment and retransmission section 14 is located between the limit flipping device 3 and the first stepped flipping device 4. A second posture guide groove 141 is provided on the surface of the posture adjustment and retransmission section 14. The second posture guide groove 141 is not only completely the same as the first posture guide groove 2 in shape and function, but can also guide the parts to gradually adjust their posture during the transmission process. It also ensures that the parts can be smoothly transferred from the third bottom feeding trough 92 to the posture adjustment and retransmission section 14 after flipping, and then enter the subsequent processing flow.

[0061] Continue to refer to Figure 3 The horizontal and vertical screening device 11 primarily consists of a second inclined feed chute 111 formed on the inner sidewall of the top tray 1 and a feed boss 112 mounted on the inner sidewall of the top tray 1. The primary function of the feed boss 112 is to carry and convey parts. Specifically, the height of the second inclined feed chute 111 is shorter than the length of the parts but greater than their width, facilitating part screening.

[0062] Continue to refer to Figure 3When a part is in a horizontal position (i.e., its length extends horizontally and its width extends vertically), it is conveyed forward at an angle within the second inclined feed trough 111. At this point, the contact area between the part and the feed boss 112 is small, with contact relying solely on the edge of the part. Consequently, conveying stability is poor, and parts can easily fall from the feed boss 112 to the next level of the feed channel 102, returning to the repositioning and retransmission section 14 for further processing.

[0063] Continue to refer to Figure 3 When the part is in a vertical position (i.e., its length extends vertically and its width extends horizontally), it can be stably placed on the feed boss 112. Its bottom surface has a large contact area with the surface of the feed boss 112, thus ensuring stability during the transfer process. Therefore, in this position, the part will not fall to the third bottom feed chute 92 under the influence of its own gravity, but can continue to be transferred to the spiral flip feed chute 12 for subsequent processing.

[0064] Continue to refer to Figure 3 The spiral flip feeding trough 12 is opened on the inner wall of the top plate 1. The spiral flip feeding trough 12 is spiral-shaped. The spiral flip feeding trough 12 is provided with a feeding end and a discharging end. When the parts in the vertical state pass through the feeding end and enter the feeding end of the torsion trough, they are conveyed and torsionally acted by the spiral flip feeding trough 12 and are conveyed from the discharging end of the spiral flip feeding trough 12 to the discharging limit device 13.

[0065] Reference Figure 1 and Figure 3 The discharge stopper 13 is located at the discharge end of the feed channel 102 and comprises a first stopper 131 and a second stopper 132. The first stopper 131 is fixed to the top plate 1. A discharge trough 133 is defined on its upper surface, wide enough to accommodate the length of the parts. The second stopper 132 is bolted into place and, together with the first stopper 131, forms the discharge channel for the parts. The distance between the lower surface of the second stopper 132 and the bottom of the discharge trough 133 is greater than the height of the parts, ensuring that the parts can be smoothly transferred to the next process as required (flat, with the metal parts facing downward).

[0066] Continue to refer to Figure 1 and Figure 3At the same time, the discharge end of the top plate 1 is provided with an arc-shaped receiving trough 105, which is provided at the discharge end of the top plate 1 and is interconnected with the discharge end of the spiral flip feed trough 12. The receiving trough 105 is arc-shaped, which is intended to reduce the impact force when the parts are discharged from the torsion trough and provide a smooth transition area. A guide groove 107 is also provided in the receiving trough 105. The end of the guide groove 107 close to the spiral flip feed trough 12 is closed to prevent the parts from falling when they have not fully entered the receiving trough 105. The end close to the discharge trough 133 is open and interconnected with the discharge trough 133. The width and depth are the same as those of the discharge trough 133 to ensure that the parts can enter the discharge trough 133 smoothly and accurately.

[0067] The working principle of the above embodiment is as follows: First, parts fall from the hopper onto the vibrating plate, where they are initially arranged and transported via the vibrating plate body and the spiral transport track within the hopper. During the transport process, the first posture guide groove 2 allows the parts to gradually adjust their posture during transport, preparing for subsequent operations.

[0068] When a part enters the position-limiting and flipping device 3, the position-limiting and flipping member 31 blocks or flips it, depending on its current position (horizontal, first vertical, or vertical). Parts in a horizontal position can easily pass through the position-limiting and flipping gap and continue to be transported. Parts in an upright position, on contact with the position-limiting and flipping member 31, flip and return to the horizontal position before continuing to be transported.

[0069] Next, the parts enter the first stepped turning device 4, passing through the stepped feed chute. Under the action of gravity, the flat parts are naturally turned to a horizontal position and fall into the first bottom feed chute 42 for further conveying. The second stepped turning device 5 is used to convey the horizontal parts and, if necessary, adjust their orientation using the air blowing mechanism 62.

[0070] In the first detection and blowing device 6, the detection mechanism 61 detects the orientation of the part. If the orientation is incorrect, the blowing mechanism 62 is activated, blowing the part into the second bottom feed trough 52 for flipping correction. The part then enters the trough conveyor device 7 and is continuously conveyed through the first inclined feed trough 71 and the vertical feed trough 72, adjusting the part's posture to a horizontal position again.

[0071] In the vertical flipping device 8, the part is transferred and flipped between the upper and lower platforms 82 and 83 of the guide base 81 according to its current orientation (the first vertical or upright state). Then, the second detection and blowing device 10 re-detects the orientation of the part and performs any necessary flip corrections.

[0072] After undergoing these posture adjustments, the parts enter the horizontal and vertical screening device 11. Here, the second inclined feed chute 111 and feed boss 112 enable parts to be screened and stably conveyed according to their posture. Finally, qualified parts enter the spiral feed chute 12 and, through the conveying and twisting action of the torsion chute, are conveyed from the discharge end to the discharge stop device 13.

[0073] In the discharge limiting device 13, the first limiting block 131 and the second limiting block 132 together form the part discharge channel, ensuring that the parts can be smoothly transferred to the next process according to processing requirements. At the same time, the curved receiving trough 105 reduces the impact force when the parts are discharged from the torsion trough and provides a smooth transition area.

[0074] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
