Description

Technical Field

[0001] This invention relates to the field of metal part inspection and conveying technology, specifically a metal part sorting, inspection and conveying device. Background Technology

[0002] In industries such as metal stamping, sheet metal processing, and electronic metal cover production, after metal sheet parts are stamped, their dimensions and weight need to be accurately inspected, and graded, sorted, and qualified products are transported based on the inspection results to ensure subsequent assembly accuracy and product yield.

[0003] Currently, for the inspection and sorting of square metal plates during the conveying and transfer process, existing inspection methods mostly involve offline sampling or using mechanical clamping arms to hold the metal parts one by one into dedicated inspection equipment for measurement. It is difficult to perform rapid online inspection of the shape, size, and weight of continuously discharged metal parts directly on the production line, resulting in a cumbersome and inefficient inspection process. Furthermore, it is impossible to automatically sort qualified and unqualified products immediately after inspection. The stacking and conveying of qualified metal parts lacks a reasonable stacking and separation structure. Existing methods often involve directly stacking metal parts, with adjacent workpieces being tightly packed together. This not only easily causes surface scratches but also makes it difficult to easily separate individual pieces in subsequent retrieval processes, seriously affecting the convenience of material retrieval and assembly cycle time. In addition, the metal parts discharged from the production line usually have a certain falling height. Directly falling into the inspection station can easily cause workpiece collisions and deformations or equipment impact damage. Existing technologies lack effective buffering and protection during the falling process, still requiring external auxiliary devices to complete the transition, further reducing the integration of the production line and the inspection efficiency. Therefore, a metal part sorting, inspection, and conveying device is needed to solve the above problems. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a metal parts sorting, inspection and conveying device.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a metal parts sorting, inspection, and conveying device, comprising an inspection body, supporting columns, supporting plates, and a fixed mounting plate.

The upper end of the sliding support plate is slidably engaged with the track conveying plate, and the front end of the first electric push rod is fixedly connected to the upper end of the sliding support plate. Side fixed mounting plates are evenly fixedly installed on both sides of the track conveying plate. The track conveyor plate, fixed connecting plate, and first electric push rod enable rapid switching and long-distance conveying of the stacking and separating main body between the working position and the conveying position. The first electric push rod drives the stacking and separating main body to slide along the track conveyor plate through the sliding support plate. When the inspection fails, the stacking and separating main body remains in a side position, which does not affect the removal of the defective products. When the inspection passes, the stacking and separating main body moves precisely to the top of the inspection body to complete the stacking and receiving. After the stacking is completed, the entire stack of qualified metal parts can be horizontally conveyed to the downstream workstation along the track conveyor plate to complete the conveying. The track conveyor plates are spliced ​​together by fixed connecting plates, which can flexibly extend the conveying stroke according to the actual production needs and adapt to the layout requirements of different production lines.

[0013] The beneficial effects of this invention are:

[0014] I. This invention achieves rapid integrated detection of the external dimensions and weight of metal parts by setting up a conical detection frame in conjunction with a multi-mode detection mechanism. The conical detection frame utilizes its top-wide and bottom-narrow structural characteristics to automatically center the falling metal parts and stop them at a height corresponding to their own dimensions. With the first laser rangefinder sensor evenly distributed on the edge of the detection plate, the external dimensions can be quickly determined by measuring the vertical distance between the bottom surface of the metal part and the sensor. The buffer auxiliary detection part set around the perimeter pushes the detection vertical plate to move inward according to a preset stroke through the fourth electric push rod. The pressure sensor collects the contact pressure in real time and assists in verifying the dimensional compliance by lateral pressure re-check. After the second electric push rod pushes the detection plate up, the weighing sensor accurately weighs the metal parts to determine whether there is any weight abnormality. The detection process does not require external clamping equipment for transfer. The metal parts can be directly slid in from the production line to complete the detection, which improves the detection efficiency. At the same time, the multi-mode verification also ensures the accuracy and reliability of the detection results.

[0015] Second, this invention achieves safe and stable reception and placement of metal parts when they are dropped from a height by setting up a buffer auxiliary detection unit. The buffer tray in the buffer auxiliary detection unit extends into the conical detection frame through the detection control groove under the drive of the third electric push rod, forming a receiving platform. Metal parts directly discharged from the production line or metal parts fed from a height by the robotic arm are first received by the buffer tray. The buffer spring effectively absorbs the impact force of the falling, avoiding the metal parts from being bumped and deformed and the equipment from being damaged. After the material is received, the buffer tray resets and exits outward, and the metal parts slide a short distance along the conical surface of the conical detection frame to the detection station. The entire material receiving and placement process is stable and controllable, without the need for mechanical clamping arms to assist in clamping and transfer. This not only protects the surface quality of the metal parts, but also extends the service life of the equipment, and simplifies the production line layout.

[0016] Third, this invention, by setting up a stacking and separating main body and its internal sliding support tray and drive control unit, realizes the neat stacking, layered and separated stacking, and convenient single-piece retrieval of qualified metal parts. The drive control unit, through the cooperation of a motor, synchronous pulley, toothed belt, and threaded adjustment rod, drives the lifting adjustment seat to accurately lift to the corresponding layer height. The seventh electric push rod and the sixth electric push rod work together to control the clamping plate to push the sliding support tray to move inward one by one, forming independent support for the bottom side of each metal part that enters. This makes the metal parts neatly stacked layer by layer from top to bottom, and adjacent metal parts do not stick to each other, completely avoiding the sticking problem caused by tight adhesion after stacking. When picking up the material, the external clamping device clamps the metal parts on both sides through the picking slot and picks them up layer by layer. The drive control unit simultaneously pulls out the sliding support tray of the corresponding layer, ensuring that there is no obstruction when picking up the material. This achieves precise single-piece retrieval, effectively avoids multiple pieces sticking together and being carried out, and greatly facilitates the need for one-by-one retrieval in subsequent assembly processes.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] like Figure 1-2As shown, a metal part sorting and inspection guiding device of the present invention includes an inspection body 7, a support column 8, a support plate 9, and a fixed mounting plate 10. The fixed mounting plate 10 is disposed at the bottom end of the inspection body 7. The support column 8 and the support plate 9 are evenly disposed between the fixed mounting plate 10 and the inspection body 7. A stacking and separating stacking body 6 is disposed above the inspection body 7. Sliding support plates 5 are fixedly connected to the upper parts of both sides of the stacking and separating stacking body 6. A track conveying plate 3 is disposed at the upper end of the sliding support plates 5. The track conveying plates 3 are spliced ​​together by fixed connecting plates 2 disposed at both ends. A first electric push rod 1 is fixedly installed on both sides of the outermost track conveying plate 3. The upper end of the sliding support plate 5 is slidably engaged with the track conveying plate 3, and the front end of the first electric push rod 1 is fixedly connected to the upper end of the sliding support plate 5. Side fixed mounting plates 4 are evenly fixedly installed on both sides of the track conveying plate 3. The inspection body 7 can be used to inspect the weight and size of the metal part 11. When the inspection meets the requirements, the first electric push rod 1 controls the stacking and separating stacking body 6 to move to the top. The detection body 7 is positioned directly above the metal parts 11 that meet the requirements, allowing them to be easily stacked into the stacking and separating body 6. If the metal parts do not meet the requirements, the stacking and separating body 6 does not move to the top of the detection body 7. At this time, the metal parts 11 that have been raised from the detection body 7 are removed by the external clamping device. When feeding materials into the detection body 7, the stacking and separating body 6 moves to the outer side above the detection body 7, making feeding convenient. The first electric push rod 1 can control the stacking and separating body 6 to slide along the track conveyor plate 3, allowing the metal parts 11 that meet the requirements to be stacked in the stacking and separating body 6 to be quickly conveyed. The track conveyor plates 3 can be easily spliced ​​together to control the conveying stroke. The first electric push rod 1 can be replaced with a long-stroke electric push rod. When using this device, it is fixedly installed on an external frame or mobile device using the side fixed mounting plate 4 and the fixed mounting plate 10. After installation, this device is electrically connected to an external control system, control display screen, and alarm.

[0032] like Figure 3-6As shown, the detection body 7 includes a conical detection frame 12. A metal part 11 to be detected is placed inside the conical detection frame 12. A bottom support plate 14 is fixedly connected to the bottom end of the conical detection frame 12. Limiting frames 15 are fixedly connected to the bottom of the outer ends of the bottom support plate 14. Buffer auxiliary detection parts 13 are provided between the outer ends of the bottom support plate 14 and the limiting frames 15. Four buffer auxiliary detection parts 13 are provided, each distributed in the middle of the outer ends of the conical detection frame 12. A detection control groove 17 is opened through the middle of the outer ends of the conical detection frame 12. A second electric push rod 16 is fixedly installed in the middle of the bottom end of the bottom support plate 14. A detection disk 18 is provided above the middle of the bottom support plate 14. The upper end of the detection disk 18... A weighing sensor 19 is installed in the middle. First laser rangefinders 20 are evenly fixedly installed along the edge of the detection plate 18. The upper end of the second electric push rod 16 passes through the bottom support plate 14 and is fixedly connected to the bottom center of the detection plate 18. The buffer auxiliary detection part 13 includes a limiting sliding vertical plate 28. A sliding adjustment plate 22 is slidably engaged at the upper end of the limiting sliding vertical plate 28. A third electric push rod 21 is fixedly installed on the outer side of the upper end of the limiting sliding vertical plate 28, and the outer end of the third electric push rod 21 is fixedly connected to the bottom of the outer end of the sliding adjustment plate 22. A buffer spring 24 is fixedly connected to the upper part of the end of the sliding adjustment plate 22 facing away from the third electric push rod 21. A buffer support plate 23 is fixedly connected to the upper end of the buffer spring 24. The upper end of the limiting sliding vertical plate 28... A fourth electric push rod 25 is fixedly installed on the outside, and the fourth electric push rod 25 is located below the third electric push rod 21. A detection vertical plate 26 is provided on the inner side of the limiting sliding vertical plate 28, and the front end of the fourth electric push rod 25 passes through the limiting sliding vertical plate 28 and connects to the middle of the inner end of the detection vertical plate 26. A pressure sensor 27 is provided between the inner end of the detection vertical plate 26 and the end of the fourth electric push rod 25. A fifth electric push rod 29 is provided on the outside of the limiting sliding vertical plate 28, and the bottom end of the fifth electric push rod 29 is fixedly connected to the bottom of the outer end of the limiting sliding vertical plate 28. The third electric push rod 21 can control each sliding adjustment plate 22 to slide along the limiting sliding vertical plate 28 and slide to the upper end of the conical detection frame 12 through the detection control groove 17. The buffer trays 23 are moved to the upper interior of the conical detection frame 12, allowing the metal parts 11 falling directly from the production height to be caught and protected by the buffer trays 23. Then, the buffer trays 23 are reset by the third electric push rod 21 and slide out of the detection control slot 17 to the outside of the conical detection frame 12. At this point, the metal parts 11 supported by the buffer trays 23 fall into the interior of the conical detection frame 12. This significantly shortens the falling detection distance, ensuring that the directly discharged metal parts 11 can safely fall into the conical detection frame 12 for detection without impact damage to either the metal parts 11 or the conical detection frame 12. Furthermore, because the conical detection frame 12 is conical with a large opening at its upper end...The falling metal part 11 is guided by the conical detection frame 12 and lands stably at a designated position inside the frame 12. The larger the size of the metal part 11, the shallower it falls into the conical detection frame 12; conversely, the smaller the size of the metal part 11, the deeper it falls into the frame 12. Based on this principle, data can be easily collected and calibrated for metal parts 11 of a fixed size, and then quickly detected using this device. Once the metal part 11 has landed at the designated position inside the conical detection frame 12, the evenly distributed first laser ranging sensors 20 analyze and judge the distance between the metal part 11 and its bottom end, and compare this distance with standard values. This allows for rapid detection of whether the metal part 11 is too large or too small. Furthermore, the first laser rangefinder sensors 20 are evenly distributed and can detect whether the metal part 11 is tilted in the conical detection frame 12. When tilted, the alarm connected to this device will sound, reminding the operator to assist in the adjustment. While the first laser rangefinder sensors 20 are detecting and analyzing, the fourth electric push rods 25 in each buffer auxiliary detection unit 13 push each detection vertical plate 26 towards the middle of the conical detection frame 12, so that the detection vertical plate 26 enters or approaches the conical detection frame 12 through the detection control groove 17, and squeezes and contacts the middle of the outer end of each metal part 11 located in the conical detection frame 12. According to the parameters and model of the metal part 11 given in advance, each fourth electric push rod 25 only controls the detection vertical plate. 26 moves forward a specified distance. At this time, the pressure value detected by the pressure sensor 27 is compared with the standard pressure value range, which can help analyze and judge whether the size of the metal part 11 meets the requirements. This makes the detection mode of the metal part 11 more diverse. At the same time, the detection plate 26 is set in a vertical plate shape, which can smoothly complete the detection of different models of metal parts 11 falling into different positions in the conical detection frame 12. After the size detection of the metal part 11 is completed, the second electric push rod 16 controls the detection plate 18 and the weighing sensor 19 to rise to support the bottom of the metal part 11 and complete the weight detection of the metal part 11. At this time, the edge of the metal part 11 no longer contacts the conical detection frame 12 after it is raised, which makes the detection accurate. The metal part 11 is conveniently discharged from the conical detection frame 12, and is supported by the bottom of the raised metal part 11. After the inspection is completed, the fifth electric push rod 29 can control the lifting and lowering adjustment of the limiting sliding vertical plate 28, thereby controlling the lifting and lowering adjustment of the buffer plate 23 and the sliding adjustment plate 22. The third electric push rod 21 moves each sliding adjustment plate 22 and buffer plate 23 to the bottom of the metal part 11 through the detection control groove 17. The limiting sliding vertical plate 28 is activated again to raise each buffer plate 23 and the limiting sliding vertical plate 28, so that the metal parts 11 that meet the inspection standards are discharged from the conical detection frame 12 and enter the highest position inside the second limiting frame 32 and the first limiting frame 30 to complete the stacking from high to low.Non-compliant metal parts (item 11) can be lifted and directly placed into the defective product stacking area by external clamping equipment.

[0033] like Figure 7-8 As shown, the stacking and separating main body 6 includes a first limiting frame 30 and a second limiting frame 32. The first limiting frame 30 and the second limiting frame 32 are arranged in a mirror-symmetrical manner. A fixed support frame 33 is fixedly installed between the side ends of the first limiting frame 30 and the second limiting frame 32. A material picking groove 31 is provided between the middle of the two sides of the second limiting frame 32 and the first limiting frame 30, and the fixed support frame 33 is located outside the material picking groove 31. Limiting frame plates 34 are symmetrically fixedly installed at the outer ends of the first limiting frame 30 and the second limiting frame 32. A drive control unit 35 is provided at the middle of the outer ends of both the first limiting frame 30 and the second limiting frame 32. A sliding support plate 39 is evenly and smoothly slidably engaged at the middle of the outer end of the first limiting frame 30 and the second limiting frame 32. An mounting plate 36 is fixedly installed at the upper middle position of the outer end of the first limiting frame 30 and the second limiting frame 32. A third laser rangefinder 38 and a second laser rangefinder 37 are fixedly installed on the mounting plate 36. The second laser rangefinder 37 is located outside the third laser rangefinder 38 and directly above the outer side of the sliding support plate 39. The third laser rangefinder 38 is located directly above the inner side of the sliding support plate 39. Through the first limiting frame 30 and the second limiting frame 32, the metal parts 11 can be sufficiently limited and stacked for stable conveying and guiding. As metal parts 11 are gradually added one by one from high to low within the space between the first and second limiting frames 30 and 32, the sliding support plates 39, which are evenly slidably disposed on the first and second limiting frames 32, automatically move towards the middle position of the first and second limiting frames 30. The sliding support plates 39 support the middle of the side ends of the metal parts 11, allowing the metal parts 11 to be neatly and separately stacked inside the first and second limiting frames 30 and 32. Furthermore, the second laser rangefinder sensor 37 detects the distance above and outside the sliding support plates 39, enabling the detection of the operating status of each sliding support plate 39 and preventing slippage. When the metal part 11 is added between the first limiting frame 30 and the second limiting frame 32, the sliding support plate 39 will not move in a way that fits the corresponding position. Similarly, by detecting the distance between the third laser ranging sensor 38 and the upper inner side of the sliding support plate 39, it can be determined whether each sliding support plate 39 slides outward and resets accordingly when the neatly stacked metal parts 11 are picked up one by one by external clamping robotic arms or other gripping devices through the material picking slot 31. This ensures that each sliding support plate 39 can accurately move and operate according to the corresponding working conditions during loading and unloading.

Inside the movable frame 40, the end of the sixth electric push rod 41 passes through the movable frame 40 and is fixedly connected to the middle of the outer end of the clamping plate 42. By starting the motor 51, the two threaded adjusting rods 45 can be rotated synchronously through the synchronous pulley 47 and the toothed belt 49. Since the lifting adjusting seat 44 is slidably limited by the sliding plate 43, the forward and reverse rotation of the threaded adjusting rods 45 can adjust the position of the lifting adjusting seat 44, thereby adjusting and controlling the position of the movable frame 40. The seventh electric push rod 50 controls the telescopic movement of the movable frame 40, and the symmetrically distributed sixth electric push rods 41 cause the clamping plates 42 symmetrically distributed in the movable frame 40 to move closer to each other. This allows each sliding support plate 39 to be clamped and pulled outwards one by one. After the two clamping plates 42 are moved and aligned with the center of the moving frame 40, the moving frame 40 and clamping plates 42 are moved forward by the seventh electric push rod 50. Each sliding support plate 39 can be inserted into the inner side of the first limiting frame 30 and the second limiting frame 32. The metal parts 11 conveyed to the second limiting frame 32 and the first limiting frame 30 can be supported on both sides of the bottom by each sliding support plate 39, so that the metal parts 11 are neatly stacked inside the second limiting frame 32 and the first limiting frame 30, which is convenient for individual clamping and picking after transfer and transportation.

[0035] The fixed connecting frame 46 is fixedly connected to the bottom middle of the first limiting frame 30 and the second limiting frame 32 respectively. The sliding plate 43 is slidably engaged on the limiting frame plate 34, which can be stably adjusted in height. The moving frame 40 is located outside the sliding support plate 39. The bottom end of the sliding support plate 5 is fixedly connected to the middle of the outer end of the fixed support frame 33. The fifth electric push rod 29 is fixedly installed on the outer end of the bottom support plate 14 and the limiting frame 15. The limiting sliding vertical plate 28 is slidably engaged on the bottom support plate 14 and the limiting frame 15. The sliding adjustment plate 22 and the buffer plate 23 are located in the middle of the detection control groove 17. The upper ends of the support column 8 and the support plate 9 are fixedly connected to the bottom edge of the conical detection frame 12, which plays a stable fixed support role.

[0036] Working Principle: In the initial state, the stacking and separating main body 6 is positioned above and to the side of the detection main body 7, without obstructing the feeding area. The buffer plate 23 in the buffer auxiliary detection section 13 is pushed by the third electric push rod 21 to slide the adjusting plate 22, which extends into the conical detection frame 12 through the detection control groove 17, forming a receiving platform. The metal parts 11 that slide down from the production line fall into the upper part of the large diameter of the conical detection frame 12, where they are first received by the buffer plate 23. The buffer spring 24 absorbs the impact force of the fall, preventing the metal parts from being bumped and deformed and the device from being damaged. After receiving the material, the third electric push rod 21 drives the buffer plate 23 to reset and exit the conical detection frame 12. After losing support, the metal parts slide a short distance along the conical surface of the conical detection frame 12, relying on the automatic centering of the conical surface to land stably at the detection station. The detection process adopts a multi-mode detection method of bottom distance measurement, side pressure re-inspection, and weighing verification. The first laser distance sensor 20 on the edge of the detection plate 18 is activated simultaneously to collect the vertical distance between the bottom surface of the metal parts and the sensor, based on the conical shape. The detection frame 12, with its wider top and narrower bottom, ensures that square metal parts 11 of the correct size will be stuck at a fixed height, with the measured distance within the standard range. If the size is too large, the stuck position will be higher; if the size is too small, the falling position will be lower. Simultaneously, the differences in the values ​​of multiple sets of sensors can determine whether the metal part is tilted. If it is tilted, an external alarm will be triggered to remind it to correct. The fourth electric push rod 25 set around the perimeter pushes the detection vertical plate 26 to move inward according to the preset standard stroke, passing through the detection control groove 17 and getting close to the side wall of the metal part 11. The pressure sensor 27 collects the contact pressure in real time. If the size is too large, the detection vertical plate 26 will contact the metal part 11 prematurely, resulting in excessive pressure. If the size is too small, there will be no effective contact or insufficient pressure even after the stroke is completed. This helps to verify the size's compliance. After the size detection is completed, the second electric push rod 16 pushes the detection plate 18 to rise, and the weighing sensor 19 lifts the metal part 11 so that it is removed from the inner wall of the conical detection frame 12. The weight of the metal part 11 is accurately collected to determine whether there are any weight abnormalities such as missing material or hidden damage. After the detection is completed, the detection plate 18 remains in the raised state and waits for sorting.

[0037] If the size or weight does not meet the standard, the stacking and separating main body 6 remains stationary in its side position. The unqualified metal parts 11 in the lifting state are directly gripped by the external robot and transferred to the defective product collection area. If all the inspections are qualified, the first electric push rod 1 drives the stacking and separating main body 6 to slide along the track conveyor plate 3 through the sliding support plate 5, and moves it precisely above the inspection main body 7. Then, the fifth electric push rod 29 drives the limiting sliding vertical plate 28 to rise as a whole. In conjunction with the third electric push rod 21, the buffer plate 23 is extended into the bottom of the metal part. The second electric push rod 16 descends slightly to transfer the metal part 11 to the buffer plate 23. Then, the buffer plate 23 lifts and conveys the metal part 11 into the top position of the stacking channel formed by the first limiting frame 30 and the second limiting frame 32. After the metal part 11 enters the stacking channel, the drive control unit 35 works with the sliding support plate 3 to move the metal part 11 into the top position of the stacking channel formed by the first limiting frame 30 and the second limiting frame 32. 9. To achieve layer-by-layer separation and stacking, the motor 51 first drives the threaded adjustment rods 45 on both sides to rotate synchronously through the synchronous pulley 47 and toothed belt 49, driving the lifting adjustment seat 44 to rise and fall along the limiting frame plate 34 to the corresponding layer height. The seventh electric push rod 50 pushes the moving frame 40 inward. The sixth electric push rod 41 drives the clamping plate 42 to clamp and push the sliding support plate 39 to move a certain distance towards the inside of the first limiting frame 30 and the second limiting frame 32 to support the bottom side of the metal part 11. The above actions are repeated from top to bottom. Each metal part is lifted and separated by an independent sliding support plate 39, achieving neat stacking without sticking to each other, avoiding the stacked pieces from sticking together. During the stacking process, the second laser range sensor 37 and the third laser range sensor 38 detect the position of the sliding support plate 39 in real time, and provide feedback on the number of stacked layers and the status of the plate to ensure stacking accuracy.

[0038] After stacking is completed, the first electric push rod 1 drives the stacking and separating stacking body 6 to move horizontally along the track conveyor plate 3, conveying the whole stack of qualified metal parts 11 to the downstream station to complete the guiding. When picking up materials downstream, the external clamping device clamps the metal parts 11 on both sides through the picking slot 31 and picks them up layer by layer. Each time a metal part 11 is picked up, the drive control unit 35 simultaneously pulls the corresponding layer's sliding support plate 39 outward a specified distance, so that the sliding support plate 39 will not cause obstruction when picking up materials, realizing accurate single-piece picking and avoiding multiple pieces sticking together and being carried out. After completing one work cycle, all components are reset and waiting for the next metal part to be fed and inspected. The track conveyor plate 3 can be extended by splicing the fixed connecting plate 2 to adapt to different conveying distances. The whole device is fixed to the production line frame or some auxiliary mobile adjustment platform by the side fixed mounting plate 4 and the fixed mounting plate 10, making the device suitable for a variety of applications.
