Description

Technical Field

[0001] This invention relates to the field of product testing technology, and specifically to an automatic product electrical characteristic testing and sorting system and method. Background Technology

[0002] In modern manufacturing, the production of electronic components, precision injection molded parts, semiconductor chips and other products is rapidly iterating towards high integration, miniaturization and multi-specification. The separation of products, electrical characteristic testing and precise material distribution are key post-processing links in the production chain, which directly determine product yield, production efficiency and downstream assembly quality.

[0003] Currently, traditional equipment in the industry generally faces the following problems: First, traditional product electrical characteristic testing and sorting equipment typically adopts a rigid, single physical structure design, which can only adapt to specific product models. When the production line switches to products with different sizes, shapes, or pin pitches, it often requires long downtime and manual replacement or adjustment of a large number of mechanical parts. This not only leads to low production efficiency and high line changeover costs, but also repeated disassembly and adjustment can easily cause wear and tear and precision degradation of key components, which in turn leads to serious problems such as material stacking, jamming, and poor conveying in subsequent processes. Second, most equipment adopts an offline process of "separation first, then testing," usually treating separation, testing, and sorting as independent physical stations or intermittent production units, resulting in limited physical space. The increased intervals and transfer links make it easy for products to shift positions during transport. Even slight positional deviations can lead to detection failures, test data fluctuations, or even equipment alarms and shutdowns, seriously affecting the accuracy, repeatability, and continuous smoothness of production. Thirdly, traditional material sorting units mainly rely on the physical size or weight of the products to perform their actions, lacking in-depth and real-time linkage with electrical performance test results. The system cannot perform precise sorting based on electrical characteristic quality data, and cannot achieve automatic quality grading and sorting, resulting in redundant processes that are prone to damage to lightweight and easily deformable products. It may also introduce human error and secondary damage, making it difficult to adapt to the production needs of multi-category, small-batch, and quick-change products. This invention proposes a new solution to the above problems. Summary of the Invention

[0004] In order to overcome at least one of the above-mentioned disadvantages, the present invention provides an automatic product electrical characteristic detection and sorting system and a detection and sorting method.

[0005] The objective of this invention can be achieved by adopting the following technical solution: A first aspect of this application provides an automatic product electrical characteristic detection and sorting system for sensor products.

The material dispensing rotary drive cylinder is used to drive the receiving channel to rotate according to the detection result of the product, so that the receiving channel is aligned with the dispensing channel corresponding to the detection result.

[0014] A second aspect of this application provides an automatic detection and sorting method for the electrical properties of manufactured products, applicable to any of the automatic detection and sorting systems for the electrical properties of manufactured products described in the first aspect.

[0018] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of the present invention more clearly, the embodiments described below are not limited thereto. The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0019] The first aspect of this application, as Figures 1-33 As shown, an automatic product electrical characteristic detection and sorting system is provided, applied to sensor products 100. Several products 100 are grouped and arranged on a carrier body 4011 to form carrier strips 401. Several carrier strips 401 are grouped and arranged within a loading fixture 311. The automatic product electrical characteristic detection and sorting system includes a loading module 102, a separation module 103, a transfer module 104, a detection module 105, and a sorting module 106. The loading module 102 is used to push the carrier strips 401 containing the products 100 to be processed out of the loading fixture 311 one by one and transfer them to the separation track. The separation module 103 is used to separate the product 100 from the carrier body 4011 after it is pushed out of the carrier strip 401. The transfer module 104 is used to grab the separated individual product 100 located on the separation track and transfer it to the transfer track 506. The detection module 105 is used to move the individual product 100 on the transfer track 506 to the detection track 601 and perform positioning, pin separation and electrical characteristic detection on the individual product 100 in sequence. The sorting module 106 is used to sort the product 100 into the corresponding receiving container according to the detection result of the detection module 105.

[0020] The automatic electrical characteristic detection and sorting system for products provided in this embodiment achieves a fully automated processing flow from loading and detection to sorting of sensor products 100 through the coordinated operation of the loading module 102, separation module 103, transfer module 104, detection module 105, and sorting module 106. The loading module 102 ensures a continuous and stable supply of carrier strip 401 from the loading fixture 311 to the processing station. The separation module 103, through horizontal alignment and lifting demolding, can efficiently and accurately separate the product 100 from the carrier body 4011 without damaging the product 100. The transfer module 104 ensures reliable transfer of the product 100 between different stations. The transfer and inspection module 105 accurately measures and judges the electrical characteristics of each product 100, while the sorting module 106 automatically classifies and collects qualified and unqualified products based on the inspection results. This effectively solves the technical problems of low efficiency, unstable quality control, and high production costs associated with traditional manual inspection and sorting, significantly improving the production efficiency and product consistency of sensor products 100. Through an adjustable mechanical structure, different products 100 can be adapted, enabling the system to flexibly meet the inspection needs of various specifications of sensor products 100. It can be widely applied to online quality inspection scenarios for multiple categories of miniaturized electronic devices, improving the system's versatility and flexibility.

[0021] Among them, the feeding module 102, as the starting point of the entire system, adopts the carrier bar 401 feeding mechanism to realize feeding one bar at a time. Relying on the feeding fixture 311, it realizes the safe storage and stable transmission of batch products 100. The feeding module 102 accurately pushes the carrier bar 401 containing a set of products 100 to be tested to the processing station one by one, and performs automatic replenishment and preparation of materials. It realizes the automated cyclic processing of the feeding fixture 311, ensuring the continuity and stability of the entire feeding process, and avoiding the inefficiency and operation error problems caused by the traditional manual feeding method.

[0022] Among them, the separation module 103 achieves non-destructive separation of product 100 from carrier body 4011 through a combination of horizontal straightening and vertical lifting. This effectively solves the technical problems that are easy to occur in traditional separation methods, such as product 100 jamming, stacking, and incomplete separation, and lays a good foundation for the accurate detection of individual products 100 in the future.

[0023] Among them, the material transfer module 104 realizes the efficient transfer of individual products 100 after separation through gripping and transfer actions. It can adapt to the transfer requirements of sensor products 100 of different specifications, ensure that the product 100 has a stable posture and accurate positioning during the transfer process, effectively avoid damage to the product 100 caused by mechanical impact or positioning deviation, and ensure the reliability and consistency of the detection process.

[0024] The detection module 105 integrates three functional units: precise positioning, pin separation, and electrical characteristic detection. It enables the automatic transfer of the product 100 between various detection stations, accurately measures the key electrical parameters of the sensor product 100, and provides real-time feedback of the detection results. This ensures the accuracy and timeliness of product quality control and provides reliable data support for subsequent intelligent sorting.

[0025] Among them, the sorting module 106 realizes intelligent classification and processing of products 100 based on the detection results. It can automatically sort qualified and unqualified products into different receiving containers according to the preset quality grade standards. It adopts a rotary sorting structure, which has fast sorting speed and high accuracy, effectively avoiding the problems of high misjudgment rate and high labor intensity in traditional manual sorting methods.

[0026] In one possible implementation, such as Figures 7-11 As shown, the feeding module 102 includes a pushing module 1021, a replenishing module 1023, and a preparation module 1022. The pushing module 1021 includes a pushing drive assembly and a feeding push rod 306. The pushing drive assembly drives the feeding push rod 306 to reciprocate, pushing the carrier strip 401 in the feeding fixture 311 into the separation track. The replenishing module 1023 includes a clamping mechanism 312, a replenishing horizontal drive cylinder 314, and a replenishing lifting drive cylinder 313. The clamping mechanism 312... The feeding horizontal drive cylinder 314 is used to clamp or release the feeding fixture 311, and the feeding horizontal drive cylinder 314 is used to drive the clamping mechanism 312 to move the feeding fixture 311 horizontally. The feeding lifting drive cylinder 313 is used to drive the clamping mechanism 312 to lift the feeding fixture 311. The material preparation module 1022 includes an upper transfer layer 310 and a lower transfer layer 309. The upper transfer layer 310 is used to store the fully loaded feeding fixture 311, and the lower transfer layer 309 is used to retrieve the empty feeding fixture 311.

[0027] Among them, the pusher module 1021 adopts the cooperation of drive components and push rods, which can reliably push the carrier bar 401 containing the product to be processed 100 out of the loading tooling 311 and accurately push it to the separation track, ensuring the continuity of product 100 supply and the accuracy of positioning.

[0028] Furthermore, such as Figure 10As shown, the feeding module 1021 also includes a mounting bracket 301, a drive motor 302, a sliding base 303, a push rod fixing member 304, a guide rail 305, and a pulley 307. The feeding module 1021 adopts a motor-driven belt transmission system and is fixed to the side of the feeding module 1023 and the preparation module 1022 via the mounting bracket 301. The feeding push rod 306 is fixed to the sliding base 303 via the push rod fixing member 304. The feeding push rod 306 moves along the carrier strip 401. The sliding base 303 is connected to the belt drive system along its length. When the loading fixture 311 moves to the designated position, the drive motor 302 drives the belt drive mechanism, causing the sliding base 303 to slide along the guide rail 305. This allows the loading push rod 306 to achieve stable lateral reciprocating motion. The loading push rod 306 contacts the end of the carrier strip 401 and continues to move, smoothly pushing the carrier strip 401 into the separation track, ensuring the smoothness and accuracy of the loading action. The entire pushing module 1021 has a compact structure and a clear transmission path, reliably pushing the carrier strips 401 out of the loading fixture 311 one by one and accurately pushing them into the separation track, significantly improving the automation level and production safety of the loading process. Sensors can also be set for identification, effectively avoiding mechanical collision damage that may occur due to positional deviation of the loading fixture 311 during the pushing process.

[0029] Among them, the feeding module 1023, through the cooperation of the clamping mechanism 312 and the dual-axis drive system, realizes the precise clamping, horizontal movement and vertical lifting operation of the unloaded feeding fixture 311, and effectively completes the automatic recycling and position adjustment of the feeding fixture 311.

[0030] Furthermore, such as Figure 11 As shown, the feeding module 1023 employs a cylinder-driven clamping mechanism 312, which reliably clamps or releases the feeding fixture 311. Through the coordinated action of the feeding horizontal drive cylinder 314 and the feeding lifting drive cylinder 313, precise displacement control of the feeding fixture 311 in the horizontal and vertical directions is achieved, enabling the feeding fixture 311 to automatically adjust its position and complete the entire process from feeding to loading. A buffer spring can be configured inside the clamping mechanism 312 to prevent mechanical damage to the feeding fixture 311 during clamping, ensuring the integrity and service life of the feeding fixture 311.

[0031] The material preparation module 1022 adopts a layered transfer structure design. The upper transfer layer 310 is responsible for storing the fully loaded loading tool 311 to maintain continuous supply, while the lower transfer layer 309 undertakes the function of collecting and temporarily storing the unloaded loading tool 311, forming a complete cyclic supply mechanism for the loading tool 311.

[0032] Furthermore, such as Figure 11As shown, the material preparation module 1022 adopts a layered transfer structure. The automated storage and retrieval of the loading fixture 311 is achieved through cylinder drive. The upper transfer layer 310 and the lower transfer layer 309 operate on the same principle, both using cylinders to move the loading fixture 311. When the upper layer is fully loaded and the loading fixture 311 is tightly fitted against the clamping mechanism 312, the replenishing clamping cylinder immediately activates to complete the clamping operation, ensuring the stability and safety of the loading fixture 311 during storage. After the loading action is completed, the unloaded loading fixture 311 is lowered to the lower transfer layer 309 via an electric cylinder drive. The automatic retrieval of the unloaded loading fixture 311 is achieved in conjunction with the cylinder-connected baffle, effectively realizing the recycling of the loading fixture 311 and improving the efficiency and automation level of the production line.

[0033] It is understandable that, such as Figure 11 As shown, the feeding module 1021, the replenishing module 1023, and the preparation module 1022 are all installed on the first mounting plate 308, and the integrated layout of the three modules is achieved by unifying the first mounting plate 308.

[0034] In one possible implementation, such as Figure 14 as well as Figures 22-25 As shown, the carrier strip 401 includes a long strip-shaped carrier body 4011 and a plurality of through holes 4012 spaced apart along its length. The product 100 includes a probe 110, a first pin 120 and a second pin 130. The probe 110 is located above the carrier body 4011, and the first pin 120 and the second pin 130 pass through the through holes 4012 and are located below the carrier body 4011.

[0035] In this embodiment, the carrier strip 401 has a long strip structure, and a number of through holes 4012 spaced along its length are adapted to the size and shape of the product 100 to ensure the stable positioning of the product 100 on the carrier. The spaced layout of the products 100 on the carrier strip 401 ensures that there will be no physical interference between adjacent products 100, effectively preventing pin swaying contact damage caused by vibration or mechanical stress during transportation.

[0036] Among them, such as Figures 22-25 As shown, probe 110 is located above vehicle body 4011, and both first pin 120 and second pin 130 extend through through hole 4012 to below vehicle body 4011, as shown. Figure 20As shown, the separation track uses two parallel conveying beams with an outer edge plate structure. A gap is formed between the two conveying beams to accommodate the pins of product 100. During the conveying process, the two conveying beams support the carrier body 4011. An outer edge plate is provided on the outside of the conveying beams, and the carrier body 4011 is located between the two outer edge plates. Whether during the feeding process or during the conveying process on the separation track, product 100 maintains a suspended posture and does not come into contact with other mechanical equipment except for the carrier body 4011. The suspended conveying method keeps product 100 in a stable posture throughout the entire transmission process. The pins and probes 110 of product 100 always maintain a safe distance from the separation track, avoiding contact damage and ensuring the integrity and detection accuracy of product 100 during the conveying process. This significantly improves the reliability of the automated production line and the stability of product quality.

[0037] Understandably, the adaptation of multiple types of sensor products 100 can be achieved by adjusting the parameters of the through hole 4012, such as the size, shape and spacing of the through hole 4012. This significantly improves the versatility and flexibility of the equipment. There is no need to disassemble or modify the production line. Only the carrier strip 401 corresponding to the product 100 needs to be customized to match products 100 of different specifications, thus reducing the cost of equipment modification.

[0038] In one possible implementation, such as Figure 12 and Figure 13 As shown, the loading fixture 311 is used to store several parallel carrier strips 401. The loading fixture 311 includes several parallel receiving grooves 3111. The opposite side walls of the receiving grooves 3111 are provided with supporting flanges 3112 to support the carrier body 4011 so that the carrier strips 401 can be suspended in the receiving grooves 3111.

[0039] In this embodiment, the feeding fixture 311 adopts a structure of multiple parallel receiving slots 3111. Each receiving slot 3111 has a supporting flange 3112 on its opposite side walls, which can reliably support the carrier body 4011 and make the carrier strip 401 stably suspended in the receiving slot 3111, thereby improving the stability and safety of the product 100 on the carrier strip 401.

[0040] Furthermore, such as Figure 13 As shown, the receiving groove 3111 has openings at both ends, which facilitates the sliding of the carrier strip 401 into the receiving groove 3111 from the openings, and also facilitates the feeding module 102 to push the carrier strip 401 from the receiving groove 3111 into the separation track from the openings.

[0041] Furthermore, such as Figure 13As shown, a limiting flange can also be provided above the supporting flange 3112. The height difference between the supporting flange 3112 and the limiting flange is greater than the thickness of the carrier body 4011. When the carrier strip 401 is loaded onto the loading fixture 311, the limiting flange is located directly above the carrier body 4011 to form a stop. At this time, the inner surfaces of the two side walls of the receiving groove 3111, the supporting flange 3112 and the limiting flange form a limit on the carrier body 4011 from four directions. During the loading process, when the loading push rod 306 contacts the carrier strip 401 and pushes it to load, the carrier strip 401 can only enter the separation track in the set direction under the restriction, which significantly improves the stability of the carrier strip 401 during the loading process.

[0042] Furthermore, the height difference between the support flange 3112 and the bottom of the receiving groove 3111 is greater than the pin length, that is, when the product 100 is suspended on the carrier strip 401, the pin does not contact the groove wall of the receiving groove 3111, thus avoiding contact damage to the pin.

[0043] In this arrangement, several products 100 are loaded in a row along a first direction onto the carrier body 4011, while multiple carrier strips 401 are spaced apart along a second direction on the loading fixture 311. The first and second directions are arranged perpendicularly, as shown below. Figure 8 As shown, the direction in which the carrier bar 401 moves away from the loading fixture 311 and enters the separation track is the first direction, and the direction in which the fully loaded loading fixture 311 replenishes materials is the second direction.

[0044] The feeding fixture 311 and carrier strip 401 provided in this embodiment are particularly suitable for batch processing of sensor products 100. The suspension support method ensures the stability of the products 100 during the transmission process, while facilitating subsequent separation, testing and other processes.

[0045] In one possible implementation, such as Figure 15 , Figure 20 and Figure 22 As shown, the automatic electrical characteristic detection and sorting system for product 100 also includes a transfer mechanism 403. The transfer mechanism 403 includes a transfer pin 4033, a transfer lifting drive cylinder 4031, and a transfer horizontal drive cylinder 4032. The carrier body 4011 is provided with several positioning holes 4013 for positioning. The transfer lifting drive cylinder 4031 is used to drive the transfer pin 4033 to rise and fall to insert into or disengage from the positioning hole 4013. The separation track includes a front track 402 and a rear track 405 connected to each other. The transfer horizontal drive cylinder 4032 is used to drive the transfer pin 4033 to move horizontally to transfer the carrier strip 401 from the front track 402 to the rear track 405.

[0046] The transplanting mechanism 403 is located between the feeding module 102 and the separating module 103. Through the cooperation of the transplanting pin 4033 and the dual-axis drive system, the dual-axis drive system achieves the precise insertion and disengagement of the transplanting pin 4033 into the positioning hole 4013 of the carrier strip 401 through the coordinated action of the transplanting lifting drive cylinder 4031 and the transplanting horizontal drive cylinder 4032, thus ensuring the stable positioning of the carrier strip 401 during the transfer process.

[0047] The connection design of the front end track 402 and the rear end track 405 of the separation track forms a continuous product 100 transmission path. The separation station of the rear end track 405 can be equipped with fiber optic sensors to identify the position of the carrier strip 401. The transfer mechanism 403 realizes the reliable positioning and accurate transfer of the carrier strip 401, solving the problems of inaccurate positioning and low transfer efficiency in the traditional manual transfer method.

[0048] Among them, such as Figure 20 and Figure 22 As shown, the positioning hole 4013 is located at the edge of the carrier body 4011, and can be located on both sides and / or at both ends of the through hole 4012. It provides a reliable positioning reference for the transplanting pin 4033. The transplanting pin 4033 can avoid the product 100 and perform precise insertion or removal operations on the positioning hole 4013, effectively avoiding direct contact between the transplanting pin 4033 and the product 100 body, and preventing mechanical damage to sensitive devices. The transplanting lifting drive cylinder 4031 drives the transplanting pin 4033 to insert or remove from the positioning hole 4013, and the transplanting horizontal drive cylinder 4032 drives the transplanting pin 4033 to move the carrier strip 401 along the separation track and reset after transfer, realizing the positioning and movement functions of the carrier strip 401 and the reset function of the transplanting mechanism 403.

[0049] In one possible implementation, such as Figures 15-21 As shown, the separation module 103 includes a straightening mechanism 406 and a lifting mechanism 407. The straightening mechanism 406 includes a straightening horizontal drive cylinder 4061 and a straightening block 4062. The straightening block 4062 is provided with a plurality of isolation strips 4063 that can be adapted to the spacing of the products 100 on the carrier strip 401. The straightening horizontal drive cylinder 4061 is used to drive the isolation strips 4063 to insert between adjacent products 100 to horizontally limit the products 100; the lifting mechanism 407... 07 includes a lifting and lowering drive cylinder 4071 and a lifting block 4072. The top of the lifting block 4072 is provided with a limiting groove 4073 for the pins of the product 100 to be inserted. After the straightening mechanism 406 completes the horizontal limiting of the product 100, the lifting and lowering drive cylinder 4071 drives the lifting block 4072 to rise so that the limiting groove 4073 contacts the pins of the product 100 and pushes the probe 110 of the product 100 away from the carrier body 4011.

[0050] In this embodiment, the separation module 103, through the cooperation of the straightening mechanism 406 and the lifting mechanism 407, allows the lifting mechanism 407 to start immediately after the straightening mechanism 406 completes the horizontal limit straightening. Through precise vertical movement, it achieves reliable separation of the product 100. It can be precisely adjusted according to the height requirements of different products 100, realizing the straightening and separation actions of the product 100 on the carrier body 4011. This ensures the smoothness and repeatability of the separation action, effectively prevents the product 100 from shifting, and ensures that the product 100 has the correct posture after separation, making it easy to grasp later.

[0051] Among them, such as Figures 16-20 As shown, the straightening mechanism 406 drives the straightening block 4062 to extend through the straightening horizontal drive cylinder 4061, so that the isolation strip 4063 on the straightening block 4062 can be accurately inserted between the pins of adjacent products 100. The outer edge plate of the separation track is provided with a clearance hole 404 for the isolation strip 4063 to pass through, so as to realize the horizontal limiting function of the product 100. The separation track forms a stop for the pins that are offset in the second direction, and the isolation strip 4063 forms a stop for the pins that are offset in the first direction. Through the coordinated cooperation of the separation track and the isolation strip 4063, a reliable positioning is formed with the product 100, ensuring that the product 100 maintains the correct posture before the separation action, and effectively avoiding the positional displacement of the product 100 due to external force or vibration during the separation process.

[0052] Furthermore, mechanical limit devices can be installed before and after the straightening horizontal drive cylinder 4061 to ensure precise control of the cylinder extension length, enabling the straightening block 4062 to achieve precise limit actions and ensuring the consistency and reliability of each separation operation. This straightening mechanism 406 has good adaptability, capable of accommodating products 100 of different specifications by adjusting the spacing of the isolation strips 4063, achieving universal processing capability for various types of sensor products 100. This provides a precise positioning basis for subsequent lifting and separation actions, significantly improving the stability and accuracy of the entire separation process.

[0053] Among them, such as Figures 15-18 as well as Figure 21As shown, the lifting mechanism 407 drives the lifting block 4072 to rise via the lifting and lowering drive cylinder 4071, so that the limiting groove 4073 on the top of the lifting block 4072 makes precise contact with the pin of the product 100 after it has been straightened by the straightening mechanism 406, thereby lifting the probe 110 of the product 100 away from the carrier body 4011 to complete the separation action. After the product 100 is horizontally limited and straightened by the straightening mechanism 406, the pin maintains an approximately vertical posture. The limiting groove 4073 of the lifting block 4072 matches the pin of the product 100, and the top limiting groove 4073 of the lifting mechanism 407 allows the pin end to be embedded in it. At this time, the lifting block 4072 continues to move upward to apply a pushing force to the pin end. The vertically rising pin is more stable and less prone to deformation, preventing damage to the product 100 such as pin deformation or breakage caused by improper force during the lifting process, and ensuring the accuracy and reliability of the separation action.

[0054] Understandably, the straightening mechanism 406 and the lifting mechanism 407 can be precisely adjusted according to the shape, size and height requirements of different products 100, which improves the versatility and flexibility of the production line, ensures the consistency and reliability of each separation operation, and effectively avoids the problem of product 100 being damaged or incompletely separated due to height mismatch.

[0055] In one possible implementation, such as Figures 26-31As shown, the material transfer module 104 includes a gripping module, a transfer module, and a pressing and limiting mechanism 508. The gripping module is used to transfer the separated individual products 100 from the rear track 405 to the transfer track 506. The gripping module includes a gripping clamp 501, a gripping horizontal drive cylinder 502, and a gripping lifting drive cylinder 503. The gripping horizontal drive cylinder 502 is used to drive the gripping clamp 501 to move the individual product 100 horizontally, and the gripping lifting drive cylinder 503 is used to drive the gripping clamp 501 to lift the individual product 100. The transfer module includes a transfer horizontal drive cylinder 504 and an elastic pusher 505. The elastic pusher 505 includes an elastic element and a push block. The push block makes elastic contact with the product 100 through the elastic element. The transfer horizontal drive cylinder 504 drives the elastic pusher... The pusher 505 pushes the product 100 received on the transfer track 506 to the linear feeder 507; the pressing and limiting mechanism 508 includes a limiting bar 5081, an elastic limiting block 5082 and a pressing and lifting drive cylinder. The elastic limiting block 5082 is located above the outlet of the linear feeder 507. The elastic limiting block 5082 is set at the end of the limiting bar 5081 and its bottom protrudes from the limiting bar 5081. The elastic limiting block 5082 and the limiting bar 5081 are elastically movable. The pressing and lifting drive cylinder is used to drive the limiting bar 5081 to rise and fall, so that a gap is formed between the limiting bar 5081 and the linear feeder 507 for the product 100 to pass through. The elastic limiting block 5082 is located on the travel trajectory of the product 100 and elastically limits the product 100.

[0056] Among them, such as Figure 31 As shown, the gripping module, as a key mechanism for serial separation and inspection, achieves reliable gripping and precise transfer of individual products 100 after separation through the cooperation of gripping fixture 501, gripping horizontal drive cylinder 502, and gripping lifting drive cylinder 503. The gripping module is fixed on the first mounting plate 308. The gripping fixture 501 securely grips the lifted individual product 100 through clamping blocks. The gripping lifting drive cylinder 503 controls the vertical movement of the gripping fixture 501, which, together with the gripping horizontal drive cylinder 502, achieves the horizontal displacement of the product 100. This effectively avoids problems such as inaccurate positioning and unstable operation that may occur in traditional manual gripping methods. Through automated control, stable gripping and reliable transfer of product 100 are achieved, providing reliable assurance for subsequent transfer and inspection processes, and significantly improving the automation level and operational efficiency of the entire production line.

[0057] Furthermore, a mechanical limit device can be configured to ensure precise control of the cylinder extension length, enabling precise position adjustment of the gripping action.

[0058] Among them, such as Figure 26 , Figure 28 , Figure 30 and Figure 31As shown, the transfer module, through the cooperation of the horizontal drive cylinder 504 and the elastic pusher 505, realizes the smooth pushing of the product 100 from the transfer track 506 to the linear feeder 507, ensuring the integrity of the product 100 during the transfer process, providing a stable and reliable supply of the product 100 for the subsequent inspection and sorting process, and realizing the connection from separation to inspection.

[0059] Furthermore, the elastic pusher 505 can adopt a combination structure of elastic element and push block. The push block forms elastic contact with the product 100 through the elastic element. The elastic element can be selected from springs, elastic sheets, etc. The horizontal drive cylinder 504 drives the elastic pusher 505 to accurately push the product 100 into the linear feeder 507. When a jam occurs during the pushing process, the spring is compressed and triggers the sensor alarm, and the equipment automatically stops running, effectively preventing damage to the product 100 caused by mechanical impact and effectively avoiding damage to the product 100 that may be caused by traditional rigid pushing. The setting of the spring anti-collision mechanism further enhances the safety protection capability of the system.

[0060] Among them, such as Figures 26-31 As shown, the downward limiting mechanism 508, by setting an elastic limiting block 5082 at the end of the limiting bar 5081 with its bottom protruding from the limiting bar 5081 and being elastically movablely connected to the limiting bar 5081, can provide a moderate elastic stop when the product 100 passes through, ensuring the normal transmission of the product 100 while avoiding damage to the product 100 caused by rigid limiting. The downward lifting drive cylinder controls the lifting movement of the limiting bar 5081, so that an appropriate feeding gap is formed between the limiting bar 5081 and the linear feeder 507, ensuring that the product 100 can pass through smoothly. The elastic limiting block 5082, which protrudes slightly from the bottom of the limiting bar 5081, can be positioned on the travel trajectory of the product 100 to form a stop, which is especially suitable for the transmission of precision components such as sensor products 100, effectively preventing deformation or damage to the product 100 caused by mechanical hard contact.

[0061] Furthermore, air-blowing plates can be installed on both sides of the linear feeder 507, optimizing the conveying environment of the product 100 and improving the stability of the transfer process. The air-blowing plates can effectively remove dust or foreign objects on the conveying path, keeping the conveying channel clean, while the airflow assists to make the product 100 move more smoothly during the conveying process. However, when the product 100 reaches the end of the linear feeder 507, due to the limiting effect of the elastic limit block 5082, the product 100 cannot overcome the elastic force to continue moving forward, ensuring the accurate positioning of the product 100 at the designated position. Through the dual protection of mechanical limiting and airflow assistance, precise control and stable operation of the product 100 conveying are achieved.

[0062] It is understandable that the transfer track 506 is similar in structure to the separation track. The transfer track 506 also includes two parallel support beams, with a gap between the two support beams for the pins to pass through. The two support beams are used to support the probe 110. When the elastic limit block 5082 contacts the product 100, specifically the probe 110, it avoids damage to the fragile pins.

[0063] In one possible implementation, such as Figures 26-32 As shown, the detection module 105 includes a positioning mechanism 602, a circulating material unloading mechanism 606, a pin separation mechanism 603, an electrical performance detection mechanism 604, a detection light source 607, and a feeding channel 605. The positioning mechanism 602 includes a positioning fixture, a positioning clamping drive cylinder, and a positioning horizontal drive cylinder. The positioning horizontal drive cylinder drives the positioning fixture to move to the end of the limit bar 5081. After the positioning clamping drive cylinder drives the positioning fixture to clamp the product 100 located at the end of the limit bar 5081, the positioning horizontal drive cylinder drives the positioning fixture to move the product 100 so that the elastic limit block 5082 automatically avoids it, and then moves the product 100 to the detection track 601 and releases the product 100. The circulating material unloading mechanism 606 includes at least three cylinder grippers, a material unloading lifting drive cylinder, and a material unloading horizontal drive cylinder. The material unloading lifting drive cylinder drives at least three cylinder grippers to lift and lower synchronously, and the material unloading horizontal drive cylinder drives at least three cylinder grippers to lift and lower synchronously. The horizontally moving, cyclically unloading mechanism 606 is used to repeatedly grip the product 100 after it is released by the positioning mechanism 602, so that the product 100 passes through the pin separation position, the electrical detection position, and the unloading position in sequence; the pin separation mechanism 603 includes a pin horizontal driving cylinder and a pin separation partition. The pin horizontal driving cylinder drives the pin separation partition to insert between the first pin 120 and the second pin 130 of the product 100 located at the pin separation position to form physical isolation; the electrical performance detection mechanism 604 includes a detection horizontal driving cylinder and a detection head. The detection horizontal driving cylinder drives the detection head to move to contact the first pin 120 and the second pin 130 of the product 100 located at the electrical detection position to perform electrical performance detection; the detection light source 607 is set above the electrical detection position to simulate the lighting environment during the detection process. The position and angle of the detection light source 607 are adjustable; the unloading channel 605 is located below the unloading position to receive the product 100 after detection.

[0064] Among them, such as Figures 26-30 as well as Figure 32As shown, the positioning mechanism 602, through the cooperation of a positioning fixture, a positioning clamping drive cylinder, and a positioning horizontal drive cylinder, achieves precise clamping and positioning of the product 100. It accurately clamps the product 100 located at the end of the limiting bar 5081. Through precise control of the positioning horizontal drive cylinder, the positioning fixture overcomes the elastic force of the elastic limiting block 5082, stably transferring the product 100 to the designated position on the detection track 601. The positioning clamping drive cylinder ensures stable clamping of the product 100 during the transfer process, preventing slippage or positional displacement due to insecure clamping. The positioning mechanism 602 has good adaptability, capable of precise adjustment according to different specifications and positional requirements of the product 100, ensuring accuracy and consistency in each positioning operation.

[0065] Among them, such as Figure 26 , Figure 28 , Figure 29 , Figure 30 as well as Figure 32 As shown, the circulating material unloading mechanism 606, through the cooperation of at least three cylinder grippers, a material unloading lifting drive cylinder, and a material unloading horizontal drive cylinder, constructs an automated circulating transfer system for the product 100 between inspection processes. Employing a multi-gripper design, at least three cylinder grippers correspond to the pin separation position, electrical detection position, and unloading position, respectively. The number of cylinder grippers can also be more than three to correspond to empty positions, enabling simultaneous gripping and releasing of multiple products 100, significantly improving inspection efficiency. Synchronous control of the material unloading lifting drive cylinder and the material unloading horizontal drive cylinder ensures precise movement of the grippers in both vertical and horizontal directions, realizing the cyclical transfer of the product 100 between the pin separation position, electrical detection position, and unloading position. The multi-point circulating design not only allows for the simultaneous processing of multiple products 100 but also enables parallel operation of various inspection processes, greatly improving the efficiency, stability, and safety of the production line. Precise mechanical control avoids potential misoperations and damage to the product 100 that may occur in traditional manual transfer methods.

[0066] Among them, such as Figure 26 , Figure 28 , Figure 29 , Figure 30 and Figure 32 As shown, the pin separation mechanism 603, through the cooperation of the pin horizontal drive cylinder and the pin separation partition, achieves reliable physical isolation of the pins of the product 100. The pin separation mechanism 603, through precise control of the pin horizontal drive cylinder, ensures that the pin separation partition is accurately inserted between the first pin 120 and the second pin 130 of the product 100 at the pin separation position, forming a stable physical isolation. This effectively avoids problems such as short circuits caused by pin overlap in traditional testing methods, ensuring the accuracy and reliability of subsequent electrical performance testing.

[0067] Understandably, the structural design of the pin separation partition can be designed according to the pin spacing requirements of different specifications of the product 100, and can adapt to the detection needs of various types of sensor products 100.

[0068] Among them, such as Figure 26 , Figure 28 , Figure 30 and Figure 32 As shown, the electrical performance testing mechanism 604, through the cooperation of a detection horizontal drive cylinder and a detection head, achieves precise contact-type electrical performance testing of the pins of product 100. The electrical performance testing mechanism 604 uses a detection horizontal drive cylinder to control the precise movement of the detection head, ensuring that the detection head accurately contacts the first pin 120 and the second pin 130 of product 100, thus achieving reliable testing of the electrical characteristics of product 100. The electrical performance testing mechanism 604, in conjunction with the pin separation mechanism 603, effectively avoids testing errors or damage to product 100 caused by poor contact or excessive contact force through pin isolation, precise mechanical control, and stable contact force adjustment, ensuring the reliability and consistency of product quality control.

[0069] Understandably, the testing head can be designed according to the contact requirements of 100 pins of different products, and can adapt to various pin contact surfaces to ensure the stability and accuracy of the testing process.

[0070] Among them, such as Figure 26 , Figure 28 , Figure 30 and Figure 32 As shown, the detection light source 607, with its adjustable position and angle design, provides an ideal lighting environment for the electrical performance testing process. Positioned above the electrical performance testing location, the detection light source 607 can simulate different lighting conditions, providing a stable illumination foundation for the testing process. The stability and uniformity of the detection light source 607 ensure the consistency of the testing process, avoiding testing errors caused by uneven illumination. The cooperation between the detection light source 607 and the electrical performance testing mechanism 604 provides crucial environmental protection for achieving high-precision electrical performance testing, significantly improving the reliability and accuracy of the test results.

[0071] Furthermore, the precise positioning and adjustment function of the light source bracket allows inspectors to adjust the illumination angle and intensity according to different inspection requirements, ensuring the best visual effect and inspection accuracy during the inspection process. The adjustable design is especially suitable for the inspection of photosensitive sensor products 100, and can meet the illumination needs of various inspection environments.

[0072] Among them, such as Figure 26 , Figure 28 , Figure 30 and Figure 32As shown, the feeding channel 605 reliably collects the inspected products 100. Located below the feeding position, the feeding channel 605 accurately receives the products 100 released from the inspection process, ensuring that the inspected products 100 can enter the corresponding receiving containers in an orderly manner. The connection between the feeding channel 605 and the inspection process ensures the continuous transmission of the inspected products 100, avoiding production interruptions caused by poor feeding, and ensuring that the inspected products 100 can accurately and safely enter the subsequent sorting process.

[0073] Understandably, the structure of the feeding channel 605 can be designed according to the size requirements of products 100 of different specifications, and can adapt to the collection needs of various types of products 100.

[0074] In one possible implementation, such as Figure 33 As shown, the sorting module 106 includes a receiving channel 706, several dispensing containers 702, several dispensing channels 703, and a dispensing rotary drive cylinder 708. The receiving channel 706 is located below the unloading channel 605 and is used to receive the inspected products 100. The several dispensing containers 702 are used to hold products 100 with different inspection results. Each dispensing container 702 is equipped with a dispensing channel 703. After being sorted by the receiving channel 706, the inspected products 100 enter the corresponding dispensing container 702 through the dispensing channel 703. The dispensing rotary drive cylinder 708 is used to drive the receiving channel 706 to rotate according to the inspection result of the product 100, so that the receiving channel 706 is aligned with the dispensing channel 703 corresponding to the inspection result.

[0075] The sorting module 106, through the cooperation of the receiving channel 706, the dispensing container 702, the dispensing channel 703, and the dispensing rotary drive cylinder 708, constructs an intelligent product 100 classification and collection system. The sorting module 106 adopts a modular design. The receiving channel 706 is located below the unloading channel 605 and can receive the inspected products 100. The dispensing rotary drive cylinder 708 drives the receiving channel 706 to rotate, realizing the automatic alignment of the receiving channel 706 with the corresponding dispensing channel 703. Each dispensing container 702 is equipped with a dedicated dispensing channel 703 to ensure that products 100 with different inspection results can be accurately diverted to the corresponding collection container.

[0076] Furthermore, the sorting module 106 also includes a material distribution tray 704, a conductive slip ring 705, and a counting sensor 707. The material distribution tray 704 is fixed to the frame 101 via a second mounting plate 701, ensuring a stable and reliable structure that is easy to maintain and adjust. The counting sensor 707 is installed on the receiving channel 706, enabling accurate counting and status monitoring of the product 100 during the unloading process, thus ensuring the accuracy of the sorting process. Several material distribution containers 702 and material distribution channels 703 are arranged circumferentially around the rotation axis. The conductive slip ring 705 installed above the rotation axis effectively solves the problem of wire crossing and entanglement during rotation, ensuring the long-term stable operation of the system.

[0077] like Figures 1-6 As shown, the automatic product electrical characteristic detection and sorting system provided in this embodiment also includes a frame 101. The overall frame of the equipment, excluding the aluminum profile frame cabinet 201, is divided into upper and lower parts by an operating table 203. The lower frame of the operating table 203 has safety doors 202 around its perimeter, each of which can be used as an inspection door for easy equipment maintenance and troubleshooting. Component mounting plates 207 are installed inside the cabinet, providing a standardized mounting medium for wiring and pneumatic circuits, ensuring the neatness and safety of the internal wiring. A safety light curtain 206, a display 204, and a control panel 205 are installed above the operating table 203, enabling convenient human-machine interaction. The front safety door 202 can also be equipped with a drawer design, providing convenient storage space for keyboards and other operating devices. Multiple safety doors 202 are provided at the top, along with viewing windows, allowing operators to observe the equipment's operating status in real time, improving the safety and convenience of equipment operation.

[0078] A second aspect of this application provides an automatic detection and sorting method for the electrical properties of manufactured products, applicable to any of the automatic detection and sorting systems for the electrical properties of manufactured products described in the first aspect. The detection method includes the following steps: A number of products to be tested 100 are loaded into a carrier body 4011 to form a carrier strip 401, and the carrier strip 401 are loaded into a loading fixture 311. The feeding module 102 automatically supplies the carrier strip 401 inside the feeding fixture 311; The separation module 103 performs horizontal positioning and lifting separation of the product 100 from the carrier strip 401; The material transfer module 104 picks up the separated individual product 100 and transfers it to the next workstation; The detection module 105 performs electrical characteristic detection on the transferred product 100; The sorting module 106 automatically sorts the products 100 into the corresponding receiving containers based on the test results.

[0079] The automatic electrical characteristic detection and sorting method for products provided in this embodiment achieves fully automated processing from input, detection, and classification. This process involves loading the feeding fixture 311 and carrier strip 401, feeding, separation, transfer, transmission, positioning, electrical characteristic detection, and finally intelligent sorting. The modules work closely together: the feeding module 102 ensures continuous supply; the separation module 103 provides precise separation of individual products 100; the transfer module 104 ensures stable transfer of products 100; the detection module 105 performs accurate electrical performance measurements; and the sorting module 106 automatically classifies products based on the detection results. Through modular design and automated control, this method significantly improves detection efficiency and product quality consistency, effectively avoiding the inefficiencies and unstable quality problems inherent in traditional manual detection methods. The entire detection and sorting process has good adaptability and scalability, allowing for adjustment of process parameters according to different product specifications 100, providing an efficient and reliable solution for modern precision manufacturing.

[0080] The automatic detection and sorting method for the electrical properties of products provided in this embodiment constructs a complete sensor product 100 processing system from feeding, detection, and sorting through a precise automated control process.

[0081] After the equipment starts, the fully loaded loading fixture 311 stored in the upper transplanting layer 310 is automatically transported to the clamping mechanism 312 position by a cylinder. The feeding horizontal drive cylinder 314 drives the clamping mechanism 312 to achieve precise positioning and locking of the loading fixture 311.
