Description

Technical Field

[0001] This invention belongs to the field of crystal oscillator manufacturing technology, specifically relating to an automatic crystal oscillator feeding device and sorting method. Background Technology

[0002] Crystal oscillators, as core frequency components in electronic devices, are widely used in communications, consumer electronics, automotive electronics, and other fields. Their production quality and efficiency directly affect the performance and cost of end products. In the automated production process of crystal oscillators, material feeding and sorting are key steps that determine overall capacity and yield.

[0003] In terms of the inspection process, existing equipment generally suffers from the dual defects of low efficiency and insufficient accuracy. On the one hand, due to the failure to solve the problem of material stacking in the feeding stage, crystal oscillators often enter the inspection station in an overlapping state, which makes it impossible for the visual recognition system to clearly capture the surface image of each crystal oscillator, resulting in missed detections or misjudgments. In the sorting and collection stages, most existing technical solutions are limited to the simple separation of good and bad products, lacking the ability to classify multi-level products (such as qualified products, defective products, and unqualified products) in a refined manner.

[0004] Therefore, how to provide an automatic crystal oscillator feeding device and sorting method that integrates automatic feeding, positive and negative identification, non-destructive testing and accurate grading functions to solve the technical problems of easy stacking of crystal oscillators, low detection efficiency and inability to automatically classify and collect them in the prior art has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

The top plate has a groove structure inside, and a spiral feeding channel is provided at the bottom and above the sides of the groove.

[0008] In one possible implementation, the spiral feeding channel is divided into multiple spiral layers, with a guiding surface between any two spiral layers; The top of the top plate is equipped with a material discharge channel and a storage bin.

[0009] In one possible implementation, the outer surface of the conveyor belt is provided with air suction holes, and multiple partition plates are fixedly arranged at equal intervals on the outer surface of the conveyor belt. The U-shaped plate has air inlets on both sides, and an air pump is installed at the lower end of the U-shaped plate.

[0010] In one possible implementation, the upper end of the support plate is symmetrically fixed with lateral adjustment sleeves, and the two lateral adjustment sleeves are slidably sleeved with lateral sleeve rods inside. A first fastening bolt is threaded onto the side wall of the lateral adjusting sleeve, and the end of the first fastening bolt passes through the lateral adjusting sleeve and is threaded onto the lateral sleeve rod. A vertical adjusting sleeve is fixedly provided at one end of the horizontal sleeve rod, and a vertical sleeve rod is movably sleeved inside the vertical adjusting sleeve. A second fastening bolt is threaded onto one side of the vertical adjusting sleeve, and the end of the second fastening bolt passes through the vertical adjusting sleeve and is threaded onto the vertical sleeve rod.

[0011] In one possible implementation, the sorting disc is driven to move horizontally and vertically reciprocatingly via transverse and longitudinal slide rails; The sorting disc is located at the bottom end of the inclined conveyor plate.

[0012] In one possible implementation, a receiving component is provided at the upper end of the box and on one side of the sorting component, the receiving component including a receiving tray rotatably disposed at the upper end of the box; The upper end of the receiving tray has a ring array of multiple receiving ports, and the lower end of each of the multiple receiving ports is provided with a receiving box.

[0013] In one possible implementation, each of the multiple receiving boxes has a sliding groove on its side, a receiving plate is slidably arranged inside each of the multiple receiving boxes, and a connecting rod is provided on one side of each of the multiple receiving plates. One end of each of the multiple connecting rods is fixedly provided with the same lifting plate, and the lower end of the lifting plate is connected to a telescopic rod.

[0014] In one possible implementation, a pusher cylinder is provided at the upper end of the housing, flush with the upper surface of the sorting disc, and a pusher plate is provided on one side of the pusher cylinder.

[0015] A sorting method using an automatic crystal oscillator feeding device, characterized by the following specific steps: S1. Start the device. The crystal oscillator in the storage bin is fed to the spiral feeding channel of the vibrating feeding mechanism through the feeding channel. Through the high-frequency vibration of the top plate and the buffering of the guide surface, the crystal oscillator rises in an orderly manner along the spiral channel. S2. The crystal oscillator enters the conveyor belt of the horizontal conveying assembly. The air pump works to generate negative pressure, which adsorbs and fixes the crystal oscillator through the air suction hole. The detection sensor identifies the front and back of the crystal oscillator. The reverse crystal oscillator is guided into the return plate of the return channel through the rejection mechanism. S3. The front crystal oscillator falls into the sorting tray via the inclined conveyor plate of the sorting component. The sorting tray moves in a horizontal and vertical reciprocating S-shape to spread the crystal oscillator evenly and avoid stacking. S4. The detection device of the detection component moves along the first transverse guide rail and the first longitudinal slide rail to simultaneously complete the appearance and electrical performance detection of the crystal oscillator, and classify the crystal oscillator into qualified products, defective products and unqualified products. The flat telescopic cylinder drives the adsorption component to move the defective products and unqualified products to the corresponding receiving port of the receiving component. S5. The receiving tray rotates, aligning the qualified product inlet with the sorting tray. The pusher plate pushes the qualified products to the corresponding receiving inlet, and the lifting receiving tray moves down synchronously to achieve buffer stacking, thus completing the sorting.

[0016] The significant technical effects of the embodiments of the present invention are as follows: (1) This invention completely solves the problem of blind spots caused by crystal stacking by setting up a sorting tray that can move horizontally and vertically to receive crystal oscillators sliding down from the inclined conveyor plate and spreading them evenly on the surface of the sorting tray in an S-shaped trajectory. With the help of an integrated detection device that can move along the horizontal and vertical guide rails, it can simultaneously complete multi-dimensional detection of crystal oscillator appearance defects and electrical performance, and automatically classify crystal oscillators into three levels: qualified products, defective products, and unqualified products. During the detection process, the crystal oscillator is always exposed to the vision system with its front facing upward, ensuring the accuracy of the identification information reading and the completeness of the surface defect identification.

[0017] (2) This invention features a rotatable receiving tray with multiple receiving ports arranged in a ring array, corresponding to qualified, defective, and unqualified products. The tray automatically switches the corresponding receiving port to the sorting tray's discharge position based on the test results. Defective and unqualified products are precisely transferred to their corresponding receiving ports via an adsorption device, while qualified products are pushed in batches via a pusher plate. The receiving box contains a lifting receiving tray that is linked to a telescopic rod. This tray moves downwards synchronously during the receiving process, ensuring a small drop between the crystal oscillator and the receiving tray surface. This prevents pin deformation or housing damage caused by direct falls, achieving non-destructive collection and neat stacking of crystal oscillators, significantly improving the final product yield.

[0018] (3) This invention utilizes the suction holes on the surface of the conveyor belt in the horizontal conveying assembly, combined with the negative pressure generated by the air pump, to firmly adhere the crystal oscillator to the surface of the conveyor belt. Combined with equally spaced separator plates, this effectively prevents the crystal oscillator from shifting or stacking during the conveying process. Simultaneously, a detection sensor identifies the front and back of the crystal oscillator. Reverse-side crystal oscillators are guided by a rejection mechanism to an adjustable-angle return plate, where they automatically fall back to the vibrating feeding mechanism for secondary sorting under gravity, thus achieving automatic recycling of defective crystal oscillators. This structural design not only ensures the stability of the feeding process but also significantly reduces the need for manual intervention and substantially improves material utilization.

[0028] Please see Figures 1-4 This illustration shows an automatic crystal oscillator feeding device according to an embodiment of the present invention, including a vibration feeding mechanism 100. The vibration feeding mechanism 100 includes a base plate 101, and a shock-absorbing rubber pad is provided on the upper end of the base plate 101 to isolate the vibration transmission during equipment operation. A base 102 is provided on the upper end of the shock-absorbing rubber pad, and an electromagnet 103 is provided inside the base 102. Spring plates are installed on the side walls of the electromagnet 103 to accumulate elastic potential energy and guide the vibration direction. A top plate 104 that can move up and down is provided on the upper end of the base 102, and an armature 105 is provided on the bottom end of the top plate 104. The electromagnet 103 is electrically connected to a controller. When the electromagnet 103 is electrically connected to the controller and driven by a pulse current, the electromagnet 103 periodically attracts the armature 105, thereby driving the top plate 104 to perform high-frequency micro-amplitude vibration. The interior of the top plate 104 has a groove structure, and a spiral feeding channel is provided on the bottom and upper side of the groove for vibrating feeding of the crystal oscillator.

[0029] The spiral feeding channel, viewed from one cross-section, consists of multiple spiral layers 106. A guide surface 107 is located between any two spiral layers 106. The inclination angle of the guide surface 107 needs to be slightly smaller than the friction angle between the crystal oscillator and the track surface. The guide surface 107 can be a continuous curved surface or a concave arc surface to increase the radius of curvature of the transition path, allowing the crystal oscillator to smoothly transition between adjacent spiral layers 106. Multiple deceleration ridges are spaced along the crystal oscillator's travel direction on the surface of the guide surface 107 to increase frictional resistance and slow the crystal oscillator's descent. An elastic buffer stop, made of flexible material, is provided at the junction of the guide surface 107 and the upper spiral layer 106 to catch the crystal oscillator sliding down from the guide surface 107, preventing a rigid collision with the edge of the upper spiral layer 106.

[0030] A conical receiving plate is provided in the middle of the top plate 104. Multiple damping springs 110 are provided on the upper surface of the conical receiving plate, and the upper end of the multiple damping springs 110 is provided with the same conical receiving sleeve plate 111. When the crystal oscillator is replenished from the storage bin 109 onto the conical receiving sleeve plate 111, the damping springs 110 will undergo elastic deformation with the impact force, slowly attenuating the impact force to prevent the crystal oscillator from falling and breaking directly. At the same time, it guides the crystal oscillator to slide smoothly down the conical surface to the spiral feeding channel, ensuring the stability of the feeding process.

[0031] A feeding device is installed at the top of the top plate 104. The feeding device includes a feeding channel 108 and a storage bin 109 fixedly installed at the top of the top plate 104. The lower end of the feeding channel 108 extends to the middle of the top of the spiral feeding channel, ensuring that the crystal oscillator can fall into the middle of the spiral feeding channel. A valve is installed on the storage bin 109, and the opening of the valve is controlled by detecting the number of crystal oscillators inside the spiral feeding channel. The upper surface of the feeding channel 108 is provided with multiple deceleration ridges, and the bottom end of the feeding channel 108 is designed with a flat opening. The width of the flat opening matches the size of the crystal oscillator, which facilitates the concentrated discharge of the crystal oscillator in a directional manner, reducing the risk of scattering and blockage. A material level sensor is installed on the side wall of the spiral feeding channel to detect the number or stacking height of crystal oscillators inside the spiral feeding channel in real time. The material level sensor is electrically connected to the controller. When the number of crystal oscillators detected is lower than the preset threshold, the controller automatically controls the valve to open, so that the crystal oscillators in the storage bin 109 are replenished into the spiral feeding channel through the feeding channel 108. When the number of crystal oscillators reaches the preset upper limit, the controller controls the valve to close, thereby realizing automatic quantitative feeding.

[0032] Compared with existing technologies, this embodiment provides an automatic crystal oscillator feeding device. By optimizing the tilt angle and buffer structure of the interlayer guide surface 107, the falling impact during crystal transition is mitigated, avoiding damage caused by rigid collisions. Simultaneously, combined with the slow-descent design of the feeding channel 108 and the linkage control of the material level sensor, quantitative and directional stable feeding of crystal oscillators is achieved. This device significantly improves the yield and automation level of the feeding process, solving the problems of easy crystal oscillator damage and uneven feeding in existing technologies.

[0033] Further, please refer to Figures 5-7 As shown, a box is provided on one side of the vibrating feeding mechanism 100, and a horizontal conveying assembly 200 is provided on the box. The horizontal conveying assembly 200 includes a horizontally arranged straight vibration channel and a return channel. The straight vibration channel includes a U-shaped plate 201 provided at the opening of the vibrating feeding mechanism 100. The lower end of the U-shaped plate 201 is connected to the top of the box.

[0034] A conveyor roller is symmetrically rotated on the inner wall of the U-shaped plate 201, and a conveyor belt 202 is sleeved on the conveyor roller. One end of one of the conveyor rollers passes through the side wall of the U-shaped plate 201 and is equipped with a conveyor motor. Multiple partition plates 203 are fixedly arranged at equal intervals on the outer surface of the conveyor belt 202. An air suction hole 204 is opened on the outer surface of the conveyor belt 202, and an air inlet 205 is opened on one side of the U-shaped plate 201. An air pump 206 is installed at the lower end of the U-shaped plate 201, and one end of the air pump 206 is connected to the air inlet 205 through a conduit. When the air pump 206 works, it creates a negative pressure in the negative pressure chamber through the air inlet 205, which then firmly adsorbs the crystal oscillator onto the surface of the conveyor belt 202 through the air suction hole 204, ensuring conveying stability. A detection sensor 207 is installed at the upper end of the U-shaped plate 201. The detection sensor 207 adopts the photoelectric sensing principle and identifies the orientation of the crystal oscillator by the reflection characteristics of light. When a crystal oscillator is detected facing down, the detection sensor 207 marks it and sends a signal to the controller. Subsequently, the marked crystal oscillator is guided into the return channel by the rejection mechanism, and then falls back into the spiral feeding channel for secondary sorting, realizing the automatic recycling of unqualified crystal oscillators.

[0035] Further, please refer to Figures 6-7 As shown, the return channel includes a support plate 208 fixedly mounted on the housing. Two mounting seats 209 are symmetrically fixedly mounted on the upper end of the support plate 208, and a return plate 210 is rotatably mounted between the two mounting seats 209 via a rotating shaft. The return plate 210 is inclined, with its lower end extending to the opening of the vibrating feeding mechanism 100 and contacting the edge of the opening. It is used to receive the reverse-facing crystal oscillators rejected from the straight vibration channel and guide them back into the spiral feeding channel by gravity, thereby realizing the cyclic feeding of defective products.

[0036] Because different crystal oscillators have different materials, package sizes, and surface finishes, their coefficients of friction with the surface of the return plate 210 vary significantly. The coefficient of friction directly affects the slid-down speed and trajectory of the crystal oscillator on the return plate 210: a higher coefficient of friction results in greater resistance to slid-down movement, making it prone to stagnation on the return plate 210; a lower coefficient of friction causes the crystal oscillator to slide down too quickly, easily resulting in impact damage when it falls into the spiral feeding channel. Therefore, the tilt angle of the return plate 210 needs to be precisely adjusted according to the specific model of the crystal oscillator.

[0037] A lateral adjusting sleeve 211 is symmetrically fixed on one side of the support plate 208 to adjust the horizontal position of the return plate 210. A lateral sleeve rod 212 is slidably fitted inside each of the two lateral adjusting sleeves 211. Multiple first threaded holes are linearly arranged along the length of the upper surface of the lateral sleeve rod 212. A first fastening bolt 213 is threaded to the side wall of the lateral adjusting sleeve 211. The end of the first fastening bolt 213 passes through the lateral adjusting sleeve 211 and is threaded to the corresponding first threaded hole on the lateral sleeve rod 212, thereby locking the lateral sleeve rod 212 within the lateral adjusting sleeve 211.

[0038] A vertical adjusting sleeve 214 is fixedly installed at the end of the horizontal sleeve rod 212 away from the horizontal adjusting sleeve 211, for adjusting the height of the return plate 210 in the vertical direction. A vertical sleeve rod 215 is movably sleeved inside the vertical adjusting sleeve 214. Multiple second threaded holes are linearly arranged along one side of the vertical sleeve rod 215. A second fastening bolt 216 is threaded onto the side wall of the vertical adjusting sleeve 214. The end of the second fastening bolt 216 passes through the vertical adjusting sleeve 214 and is threaded into the corresponding second threaded hole on the vertical sleeve rod 215, thereby locking the vertical sleeve rod 215 inside the vertical adjusting sleeve 214. The upper end of the vertical sleeve rod 215 is hinged to the bottom of the return plate 210.

[0039] When replacing crystal oscillators with different models, the operator, based on the friction coefficient of the crystal oscillator and referring to the preset adjustment parameters, first loosens the first fastening bolt 213. Then, by extending and retracting the horizontal sleeve 212 within the horizontal adjusting sleeve 211, the horizontal projection position of the return plate 210 is adjusted. Simultaneously, the second fastening bolt 216 is loosened, and by raising and lowering the vertical sleeve 215 within the vertical adjusting sleeve 214, the support point height of the return plate 210 is adjusted. The coordinated adjustment of the horizontal position and support height jointly determines the tilt angle of the return plate 210 relative to the horizontal plane. For crystal oscillators with a lower friction coefficient, the tilt angle of the return plate 210 needs to be reduced to slow down the descent speed; for crystal oscillators with a higher friction coefficient, the tilt angle needs to be appropriately increased to ensure smooth descent. After adjustment, the first fastening bolt 213 and the second fastening bolt 216 are tightened respectively to fix the posture of the return plate 210.

[0040] A pusher cylinder is provided on one side of the U-shaped plate 201. The pusher cylinder is used to push the crystal oscillator, which is reversed after being detected by the detection sensor 207, from the direct vibration channel to the return channel.

[0041] Compared with the prior art, this embodiment provides an automatic crystal oscillator feeding device. By setting up a horizontal feeding component 200 with negative pressure adsorption and positive and negative detection, and combining it with an angle-adjustable return plate 210, it realizes stable feeding of crystal oscillators and recycling of defective products. It solves the problems of easy deviation of crystal oscillator feeding and inability to automatically reuse crystal oscillators with reverse side down in the prior art, and significantly improves feeding efficiency.

[0042] Example 2: Based on Example 1, please refer to... Figure 8 , Figure 9 As shown, a sorting assembly 300 is installed at the upper end of the housing. The sorting assembly 300 includes an inclined conveyor plate 301 fixed by two symmetrical columns. The upper end of the inclined conveyor plate 301 contacts the side of the conveyor belt 202. A sorting disc 302 is installed in the middle of the upper surface of the housing. The sorting disc 302 can move horizontally and vertically reciprocally via transverse and longitudinal slide rails. The sorting disc 302 is located at the bottom end of the inclined conveyor plate 301 and is used to receive crystal oscillators that are facing upwards and slowly slide down from the inclined conveyor plate 301. It performs fine inspection on the crystal oscillators facing upwards and rejects unqualified products. The transverse and longitudinal slide rails are reciprocated by a motor, a lead screw, and a slider. The inspection items mainly cover two aspects: appearance inspection and electrical performance inspection. Appearance inspection includes surface defects and packaging integrity, while electrical performance inspection includes nominal frequency accuracy and resonant resistance. The transverse and longitudinal slide rails can be reciprocated by a motor, a lead screw, and a slider.

[0043] The crystal oscillators slowly conveyed from the upper end of the inclined conveyor plate 301 can slowly fall onto the sorting tray 302. Simultaneously, the sorting tray 302 can move horizontally and vertically back and forth, causing the crystal oscillators to disperse in the middle of the sorting tray 302, avoiding stacking. When receiving crystal oscillators, the sorting tray 302 is S-shaped, ensuring the crystal oscillators are evenly distributed on its upper surface. After a batch of crystal oscillators has been conveyed, the conveyor belt 202 stops conveying, and sorting begins. The horizontal and vertical movement of the sorting tray 302 does not interfere with the receiving tray 401 because the height of the sorting tray 302 is higher. Furthermore, when receiving qualified products, the sorting tray 302 slowly moves until it is in contact with the receiving tray 401.

[0044] A detection component is installed at the top of the housing and above the sorting tray 302. This detection component integrates a high-resolution industrial camera and a crystal parameter tester to perform comprehensive quality inspection on the crystal oscillator and automatically classify the crystal oscillator into three levels: qualified, defective, and unqualified, based on the inspection results.

[0045] Qualified products refer to those with intact appearance, electrical parameters that meet specifications, and reliability standards for the corresponding application scenario; defective products refer to those with minor scratches or blurred markings that do not affect electrical performance; unqualified products refer to those with serious appearance defects such as cracks or broken pins, or fatal problems such as out-of-tolerance electrical parameters or no output frequency. Crystal oscillators are placed face up into sorting tray 302 because the front is printed with identification information such as model and frequency, facilitating accurate reading and verification by the vision system. Simultaneously, the front, as the primary inspection surface, must be fully exposed to the vision system to ensure accurate identification of surface scratches, contamination, and other defects, thereby guaranteeing the authenticity of the inspection results and the reliability of subsequent processes.

[0046] The detection assembly includes a U-shaped frame 303 fixedly mounted on the upper end of the housing. A first transverse guide rail 304 is mounted on the upper end of the U-shaped frame 303. A first slider 305 is slidably mounted on the upper end of the first transverse guide rail 304. The transverse sliding of the first slider 305 is achieved by a motor and a lead screw connected to the motor, both located on one side of the first transverse guide rail 304. The lead screw is threadedly connected to the first slider 305, and the first slider 305 is slidably engaged with the first transverse guide rail 304. When the motor receives a drive signal from the controller, it starts operating, and the motor output shaft drives the lead screw to rotate synchronously. Because the first slider 305 is threadedly connected to the lead screw and slidably engaged with the first transverse guide rail 304, the rotational motion of the lead screw is converted into linear motion of the first slider 305 along the first transverse guide rail 304. A first longitudinal slide rail 306 is fixedly mounted on the upper end of the first slider 305. A second slider 307 is slidably engaged on the first longitudinal slide rail 306. The second slider 307 also achieves its longitudinal reciprocating sliding through a motor and a lead screw. A detection device 308 is provided on one side of the second slider 307. This detection device 308 is an integrated vision and electrical inspection module, which internally encapsulates a high-resolution industrial camera, a microscope lens, a ring light source, and a retractable miniature test probe. The industrial camera is used to acquire images of the crystal oscillator surface to identify appearance defects such as scratches, contamination, and blurred markings. The miniature test probe is driven by a cylinder to extend downwards and contact the crystal oscillator pins to measure electrical parameters such as frequency accuracy and resonant resistance in real time. The detection data is transmitted back to the controller in real time for analysis and judgment. A flat telescopic cylinder 309 is provided on the other side of the second slider 307. An adsorption component 310 is provided at the lower end of the flat telescopic cylinder 309. This adsorption component 310 is a miniature vacuum nozzle. Its lower opening matches the shape of the crystal oscillator, and its upper end is connected to a vacuum generator inside the housing through a flexible air tube. The start and stop of the vacuum generator are controlled by the controller based on the detection results.

[0047] When a defective or substandard product is detected, the flat telescopic cylinder 309 directly moves the adsorption element 310 downward, transferring the crystal oscillator to the corresponding defective or substandard product collection channel. Qualified products remain on the sorting tray 302. A pushing cylinder is installed flush with the upper surface of the sorting tray 302 at the top of the housing. A pushing plate 311 is installed on one side of the pushing cylinder, which pushes the qualified products placed on the upper surface of the sorting tray 302 to the qualified product collection channel.

[0048] With the continuous improvement of industrial production levels, the pass rate of product production lines is constantly rising, while the proportion of defective and unqualified products is correspondingly reduced to a lower level. Based on this trend, the actual working frequency of the adsorption component 310 is significantly reduced. After the sorting and removal of a small number of defective and unqualified products, the remaining large number of qualified products can be directly pushed to the next process in batches by the pushing mechanism, without the need for individual adsorption processing. This effectively simplifies the operation process and improves overall production efficiency.

[0049] Compared with the prior art, this embodiment provides an automatic crystal oscillator feeding device. By setting a two-dimensional movable sorting disk 302 in conjunction with an S-shaped spreading trajectory, and combining an integrated detection component and a vacuum adsorption rejection mechanism, it realizes the automatic spreading, multi-dimensional detection and graded collection of crystal oscillators, which significantly improves detection efficiency and sorting accuracy, and solves the problems of easy stacking of crystal oscillators and untimely rejection of defective products in the prior art.

[0050] Example 3: Based on Examples 1 and 2, please refer to... Figures 10-12 As shown, a receiving component 400 is provided on one side of the sorting component 300 at the upper end of the box. The receiving component 400 includes a receiving tray 401 that is rotatably disposed at the upper end of the box. The receiving tray 401 and the sorting tray 302 do not interfere with each other in horizontal and vertical movement. The receiving tray 401 rotates via a motor, a drive gear, and a driven gear. A driven gear is sleeved on the surface of the support rod at the lower end of the receiving tray 401. The motor drives the drive gear to rotate, which in turn drives the driven gear meshing with it to rotate, thus rotating the receiving tray 401. The upper end of the receiving tray 401 has multiple receiving ports 402 arranged in a circular array. These ports are for qualified products, defective products, and unqualified products, respectively. Each receiving port 402 has a receiving box 403 at its lower end. Each receiving box 403 has a sliding groove 404 on its side. Each receiving box 403 has a receiving plate 405 slidably installed inside it. Each receiving plate 405 has a connecting rod 406 on one side. One end of each connecting rod 406 is fixedly connected to the same lifting plate 407. The lower end of the lifting plate 407 is connected to a telescopic rod 408.

[0051] When receiving defective and non-conforming products, the controller drives the receiving tray 401 to rotate, adjusting the defective or non-conforming product inlet to correspond with the discharge position of the sorting tray 302. Then, the telescopic rod 408 extends, simultaneously moving multiple receiving trays 405 upwards to a receiving position near the receiving port 402 via the lifting tray 407 and connecting rod 406. At this time, the flat telescopic cylinder 309 drives the adsorption element 310 downwards, adsorbing the defective or non-conforming products as determined by inspection and transferring them to the corresponding receiving port 402 for release. The crystal oscillator falls onto the receiving tray 405 below. Since the number of non-conforming and defective products is relatively small, the telescopic rod 408 moves downwards only a small distance. After each batch of defective or non-conforming products is transferred, the controller drives the receiving tray 401 to rotate again, aligning the conforming product inlet with the discharge position of the sorting tray 302. As the pusher plate 311 slowly pushes the qualified products gathered on the upper surface of the sorting tray 302 into the qualified product inlet, the telescopic rod 408 simultaneously drives the receiving tray 405 to slowly and uniformly move downwards. This ensures that the falling crystal oscillators maintain a small drop difference from the upper surface of the receiving tray 405, preventing direct impact damage from the crystal oscillators and achieving neat stacking and collection of multi-layer crystal oscillators. Through the above structure, the receiving component 400 not only achieves the classified collection of crystal oscillators of different grades, but also effectively protects the integrity of the crystal oscillators during the receiving process through the lifting and buffering of the receiving tray 405, improving the final product yield. A door that can be opened is provided on one side of the receiving box 403, and a conveyor belt can be installed on one side of the receiving component 400. The doors of the boxes for qualified products, defective products, and unqualified products can be opened sequentially to remove the crystal oscillators inside, allowing the crystal oscillators to be transported out intermittently.

[0052] Compared with the prior art, this embodiment provides an automatic crystal oscillator feeding device. By setting a rotatable receiving tray 401 in conjunction with multiple graded feeding ports, and combining a lifting receiving tray 405 with a telescopic rod 408 linkage mechanism, it realizes the automatic classification, collection and buffer stacking of qualified products, defective products and unqualified products. It effectively solves the problems of chaotic receiving and easy damage to crystal oscillators by falling in the prior art, and significantly improves the collection quality and classification efficiency of products.

[0053] Please see Figures 1-12 As shown, this application provides a sorting method, comprising the following steps: S1: Start the device. The crystal oscillator in the storage bin 109 is fed to the spiral feeding channel of the vibrating feeding mechanism 100 through the feeding channel 108. Through the high-frequency vibration of the top plate 104 and the buffering of the guide surface 107, the crystal oscillator rises in an orderly manner along the spiral channel. S2: The crystal oscillator enters the conveyor belt 202 of the horizontal conveying assembly 200. The air pump 206 works to generate negative pressure, which adsorbs and fixes the crystal oscillator through the air suction hole 204. The detection sensor 207 identifies the front and back of the crystal oscillator. The reverse crystal oscillator is introduced into the return plate 210 of the return channel through the rejection mechanism. S3: The front crystal oscillator falls into the sorting tray 302 via the inclined conveyor plate 301 of the sorting component 300. The sorting tray 302 moves horizontally and vertically in an S-shape to spread the crystal oscillator evenly and avoid stacking. S4: The detection device 308 of the detection component moves along the first transverse guide rail 304 and the first longitudinal slide rail 306, and simultaneously completes the appearance and electrical performance detection of the crystal oscillator, classifying the crystal oscillator into qualified products, defective products and unqualified products. The flat telescopic cylinder 309 drives the adsorption component 310 to move the defective products and unqualified products to the corresponding receiving port 402 of the receiving component 400. S5: The receiving tray 401 rotates, so that the qualified product inlet connects with the sorting tray 302. The pusher plate 311 pushes the qualified product to the corresponding receiving inlet 402. The lifting receiving tray 405 moves down synchronously to achieve buffer stacking and complete the sorting.
