By detecting the height of water pump accessories, it can be directly known whether the production of accessories meets the specifications.

[0003] In the related art (publication number CN115854948B), a water pump accessory detection device is disclosed, including a conveyor belt for conveying water pump accessories. In order to facilitate the detection of water pump accessories, the present invention is provided with a conveyor belt for conveying water pump accessories. When detecting the height of water pump accessories, it is judged by detecting the height from the upper surface of the water pump accessory to the first detection head. A box body is arranged on the conveyor belt, and the water pump accessory is placed on the box body. The inner bottom surface of the box body is parallel, and the water pump accessory can be stably placed. At this time, the height from the inner bottom surface of the box body to the first detection head is detected by the first detection head as H1, and the height from the surface of the water pump accessory to the first detection head is detected by the first detection head as H2. H1 - H2 = the height of the water pump accessory. The present invention can complete the dimensional detection of water pump accessories during the conveying process by using the conveyor belt, and avoid the phenomenon of generating errors.

Especially when facing large-scale and batch water pump accessory detection tasks, due to the limited speed of manual operation and the difficulty in realizing an automated continuous detection process, it cannot meet the actual needs of high-efficiency detection, affecting the overall detection efficiency and production capacity.

[0035] Compared with the prior art, the water pump accessories detection device of the present invention has the following beneficial effects:

[0036] 1. With respect to the traditional manual-led detection method, the detection efficiency is low, especially when facing large-scale and batch water pump parts detection tasks, due to the limited speed of manual operation and the difficulty in realizing the automated continuous detection process, it is unable to meet the actual needs of efficient detection, affecting the overall detection efficiency and production capacity. The present invention can guide and limit the parts to be detected through the guide unit, and can convey the parts body one by one through the interval conveying unit, so as to ensure that each part body can automatically and orderly enter the detection unit and the pushing unit for detection, that is, the present device can realize the equidistant interval conveying and automated detection of the parts body one by one. Compared with the traditional manual-led detection method, it can realize the automated continuous detection process, which is more efficient, more suitable for large-scale and batch water pump parts detection tasks, and can better ensure the overall detection efficiency and production capacity;

[0037] Second, in the present invention, two groups of seats are arranged to be symmetrical in front and back and to swing back and forth, and to work together with the conveying function of the conveying device to achieve the effect of accurately and orderly releasing the accessory body one by one to the right, that is, the accessory body can be stably conveyed to the right to a specific inspection station in an evenly spaced manner. Compared with the traditional manual placement method, the interference of human error factors is effectively reduced. At the same time, combined with the reciprocating lifting and lowering function characteristics of the induction switch and the first contact at the detection unit detection point, a complete and efficient inspection process system is successfully constructed, thereby realizing the continuous operation of the inspection operation, greatly improving the efficiency and reliability of the overall inspection work;

[0038] 3. In the present invention, by means of the circular motion of the turntable and the cooperation of the toggle pin, the moving frame, the moving plate, the driving rod, the hollow block, etc., the seat body can be made to swing back and forth with the supporting rod as the axis, that is, the circular motion is converted into horizontal reciprocating motion and then the continuous reciprocating swing of the seat body is achieved, that is, the turntable can achieve the reciprocating swing of the seat body without changing the rotation direction. Compared with the method of frequently changing the driving force direction to achieve the reciprocating swing of the seat body, the additional energy loss caused by the frequent switching of the driving force direction is avoided, so that the consumption of driving force can be more effectively saved, the system operation cost can be reduced, and a reliable guarantee is provided for the long-term, efficient and stable reciprocating swing operation of the seat body;

[0039] Fourth, in the present invention, by setting the limit seat, the limit wheel and the limit strip, it can ensure that the movable plate can move relatively more smoothly in the limit seat, which is smoother than the sliding mode of the movable plate directly contacting the inner wall of the limit seat, reducing the resistance generated during the friction process, and is more conducive to extending the service life of the components;

[0040] 5. By providing the hollow block, the present invention can leave sufficient space for the movement of the driving rod, avoiding the problem that the movement of the driving rod is restricted by the seat body when the driving rod is directly connected to the seat body;

[0041] 6. By providing two rollers on the seat body, the present invention can limit and guide the accessory body while avoiding abrasion of the accessory body caused by direct contact between the seat body and the accessory body. On the premise of ensuring equidistant conveyance of the accessory body, the integrity of the accessory body is guaranteed not to be damaged;

[0042] 7. In the present invention, through the first rotating shaft, the first motor, the second bevel gear, the first bevel gear, and the third bevel gear, the front and rear groups of rotating rods can be driven to rotate in opposite directions, that is, it is ensured that the front and rear groups of turntables drive the corresponding toggle pins to rotate synchronously, further ensuring the synchronization and unity of the final actions of the front and rear groups of seat bodies. That is, the present invention realizes the stable and coordinated rotation of the front and rear corresponding groups of seat bodies in opposite directions by means of a single driving power source, improving the mechanical transmission efficiency and motion control accuracy of the entire device;

[0043] 8. In the present invention, when the ends of the two seat body components approach each other, the formed space distance is smaller than the diameter size of the accessory body, which can effectively block and limit the accessory body in the area between the two seat bodies. When the end of the seat body is converted to the open state, it cooperates with the conveying function of the conveying device to achieve the goal of sequentially releasing the accessory bodies one by one. As a result, the accessory bodies can smoothly enter the subsequent detection stations and carry out the individual detection process in an orderly manner, thus successfully constructing a highly automated, highly coherent detection process, and a tightly efficient production rhythm detection operation system. This system effectively reduces the manual intervention link, significantly improves the detection efficiency and quality control level, and provides strong technical support for the quality inspection link of water pump accessories;

[0044] 9. For the existing commonly used water pump accessory detection devices, when in use, they can only simply distinguish between two situations of qualified and unqualified accessories in terms of height. However, the unqualified accessories with high height are divided into two types: high and low, and the existing detection devices cannot distinguish between the above situations. In this application, through the cooperation of components such as the induction switch, the first contact, and the second contact, three situations of accessories that meet the height requirements, accessories higher than the qualified height, and accessories lower than the qualified height can be detected, that is, the accessories can be finely detected and distinguished, and combined with subsequent fine classification and collection, the cumbersome steps of secondary classification and processing of unqualified accessories are saved, and the process is more efficient;

[0045] 10. The present invention specifically sets up corresponding collection systems for three types of accessories: accessories that meet height requirements, accessories that are higher than the qualified height, and accessories that are lower than the qualified height. While realizing the height detection of accessories, it also realizes the classified collection and processing of accessories in different situations, realizing the integration of detection and classification. In the future, accessories that are higher than the qualified height can be processed by secondary cutting, thereby reducing production costs and optimizing resource allocation, and realizing the maximum utilization of defective accessories.

[0046] 11. The present invention is provided with a swing arm, a first push rod, and a second push rod. After detecting the corresponding accessories, the first push rod or the second push rod can be rotated to push the accessories to the corresponding first material trough or the second material trough for subsequent collection. At the same time, the first push rod and the second push rod can be used to limit the main body of the accessories during the detection process, ensuring that the main body of the accessories is always under the induction switch, thereby ensuring the accuracy of the subsequent detection results. That is, the setting of the pushing unit realizes the organic unity of the limiting function and the targeted pushing function during the detection of the main body of the accessories, and achieves the effect of multiple uses of one component. Compared with the traditional mode of separately setting two functional mechanisms, this integrated design can significantly save the installation space inside the equipment, optimize the overall structural layout, and improve the space utilization and compactness of the equipment;

[0047] 12. In the present invention, by providing the first feeding trough and the second feeding trough, it is possible to realize the separate conveying of qualified parts and unqualified parts. By providing two sets of screening channels at the second feeding trough and cooperating with the guide limit of the toggle plate, it is possible to further distinguish and collect the unqualified parts in a targeted manner. The fine classification of unqualified parts is helpful to formulate more reasonable reuse plans for different types of defective parts, thereby improving the utilization rate of raw materials and reducing the scrap rate and production cost.

[0048] 13. In the present invention, a swingable toggle plate is provided, which can guide and transport unqualified products corresponding to different situations after detection to the screening channels at corresponding positions, so as to carry out targeted collection later;

[0049] 14. On the basis of classifying and conveying unqualified fitting bodies according to height, the present invention also has a secondary sorting function in the corresponding screening channels, that is, in the collection channels of fitting bodies with a height lower than that of qualified products, the uncollected fitting bodies with a height lower than that of qualified products can be sorted. Similarly, in the collection channels of fitting bodies with a height higher than that of qualified products, the uncollected fitting bodies with a height higher than that of qualified products can be sorted. That is, the present invention has a secondary sorting function for unqualified products, which can avoid the omission of unqualified fitting bodies during sorting on their respective channels, ensure that each unqualified product can be accurately identified and processed, avoid unnecessary processes such as repeated detection and rework caused by omission, and the precise secondary sorting can reduce problems such as waste of raw materials, increase in labor costs, and equipment wear caused by the mixing of unqualified products into subsequent links, making the entire production process smoother and more efficient, and reducing time waste and resource consumption in the production cycle;

[0050] 15. By means of the installation rod and the second touch switch provided in the present invention, when the fitting body touches the second touch switch, the push plate, the cross bar, and the side plate can move synchronously outward, pushing the fitting body out of the corresponding second groove outward. With this setting, on the one hand, it can meet the centralized collection of fittings with a height higher than the qualified height in the left screening channel, and on the other hand, it can perform secondary sorting on the fittings with a height higher than the qualified height that are omitted in the right screening channel. That is, this setting realizes the efficient and precise conveying and collection of fittings with a height higher than the qualified height to the side in the above two different situations, greatly improving the reliability, integrity, and intelligent level of the entire sorting system;

[0051] 16. In the present invention, through the cooperation of components such as the screw rod, the optical rod, and the fixed seat, the height of the installation rod, the fixed piece, and the second touch switch can be adjusted to flexibly adjust the height of the second touch switch for fitting bodies of different batches and different heights, so that the height where the second touch switch is located can detect unqualified fittings with a height higher than that of qualified fittings. That is, through this height adaptability adjustment, it is ensured that the second touch switch is always at an optimal height level that can accurately detect unqualified fittings with a height higher than that of qualified fittings. That is, this equipment has high flexibility and adaptability, can effectively meet the diverse needs of fitting bodies of different batches and different heights in the detection link, and expands the scope of use and detection efficiency of the equipment in actual production applications.

[0052] In summary, firstly, this equipment realizes an automated inspection process. Compared with the traditional manual inspection method, it guides, limits and transports the inspected accessories one by one through specific components, and can automatically and orderly deliver the accessories to the inspection area, meeting the needs of large-scale and batch inspection tasks, greatly improving the inspection efficiency, effectively ensuring the overall inspection efficiency and capacity improvement, reducing the errors and limitations caused by manual operation, and enhancing the accuracy and stability of inspection; secondly, with the help of a series of components, the conversion from circular motion to horizontal reciprocating motion is realized, and the related components are driven to rotate or swing in a stable and coordinated manner, which not only ensures the synchronization and continuity of the movements, but also avoids the energy loss caused by frequent switching of the driving force direction, reduces the system operation cost, and extends the service life of the components. At the same time, it provides reliable guarantee for long-term, efficient and stable operation, and improves the mechanical transmission efficiency and motion control accuracy; in addition, in terms of detection accuracy and classification collection, it can accurately Refined detection distinguishes three situations: accessories that meet height requirements, accessories that are higher than the qualified height, and accessories that are lower than the qualified height. Corresponding collection systems are set up in a targeted manner to achieve integrated detection and classification, save secondary sorting and processing procedures, and adapt to the detection needs of accessories of different heights in different batches through adjustable components, improve equipment flexibility and adaptability, expand the scope of use and detection efficiency, and can distinguish and collect unqualified accessories in a high and low detailed manner, which is helpful to formulate reasonable reuse plans, improve the utilization rate of raw materials, and reduce scrap rate and production costs. In addition, it also has the function of secondary sorting of unqualified products, which can avoid sorting omissions and reduce various problems caused by unqualified products mixed into subsequent links, making the production process smoother and more efficient, reducing time and resource consumption, and improving the reliability, integrity and intelligence level of the entire sorting system, optimizing the overall structural layout, and improving the space utilization and compactness of equipment, providing sufficient guarantee for the quality inspection of water pump accessories.

The intermittent conveying unit 3 also includes a driving mechanism arranged above the two groups of intermittent conveying mechanisms, which is used to realize the synchronous and opposite-direction movement of the two groups of intermittent conveying mechanisms, improving the mechanical transmission efficiency and motion control accuracy of the entire device;

[0075] Refer mainly to Figure 6 、 Figure 8 、 Figure 10 and Figure 11As shown, each group of interval conveying mechanisms includes a first bracket 3001 fixedly mounted on the first mounting plate 2, a rotating rod 3002 is rotatably arranged on the first bracket 3001 along the vertical direction through a bearing, a rotating disk 3003 is fixedly mounted on the bottom end of the rotating rod 3002, a driving pin 3004 is installed on the lower surface of the rotating disk 3003, and the driving pin 3004 is arranged at an eccentric position of the rotating disk 3003. With the help of the rotation of the rotating rod 3002, the rotating disk 3003 can be driven to rotate, thereby realizing the circumferential rotation of the driving pin 3004 relative to the center of the rotating disk 3003, and a moving frame 3005 is slidably sleeved on the driving pin 3004, wherein the length of the inner cavity of the moving frame 3005 is greater than the diameter of the rotating disk 3003. The movable frame 3005 has a diameter, thereby ensuring that there is enough space for the toggle pin 3004 to rotate in a circular direction, thereby avoiding the circular motion of the toggle pin 3004 being affected by the limited space in the inner cavity of the movable frame 3005; the side wall of the movable frame 3005 is fixed and vertically mounted with one end of the movable plate 3006, when the toggle pin 3004 rotates in a circular direction, it can drive the movable frame 3005 to reciprocate in the horizontal direction, and the second bracket 3007 is also fixedly mounted on the first mounting plate 2, and the second bracket 3007 provides support for the subsequent installation of other components, and the second bracket 3007 is fixedly mounted with a limited seat 3008, and the movable plate 3006 slides in the horizontal direction through the inner cavity of the limited seat 3008, through The limit seat 3008 can limit the moving direction of the moving plate 3006 to ensure that the moving frame 3005 drives the moving plate 3006 to move in the horizontal direction. The other end of the moving plate 3006 is rotatably connected to the driving rod 3011 through a pin shaft. When the moving plate 3006 moves in the horizontal direction, it can drive the rotating connection between the moving plate 3006 and the driving rod 3011 to move together. A moving pin 3017 is installed on the side of the driving rod 3011 away from the moving plate 3006. A support rod 3012 is vertically installed on the second bracket 3007. The top of the support rod 3012 is rotatably connected to a connecting block 3013 through a bearing. The side wall of the connecting block 3013 is fixedly installed with a seat body 3014. The seat body 3014 The two ends are rotatably connected with rollers 3015 through bearings, and a hollow block 3016 is installed on the side wall of the seat body 3014. The moving pin 3017 is slidably embedded in the inner cavity of the hollow block 3016. The circumferentially rotating turntable 3003 prompts the toggle pin 3004 to drive the moving frame 3005 to reciprocate and move left and right, so that the moving plate 3006 drives one end of the driving rod 3011 to move back and forth synchronously. At this time, the seat body 3014 prompts the seat body 3014 to reciprocate and swing in the forward and reverse directions with the support rod 3012 as the axis, and the front and rear groups of seat bodies 3014 swing at the same angle and in opposite directions. Specifically, when the left ends of the front and rear groups of seat bodies 3014 are far away from each other and the right ends are close (refer to Figure 5 and Figure 7 In the state shown), the distance between the right ends of the two seats 3014 is less than the diameter of the accessory body 10;

[0076] Specifically, when the two groups of seat bodies 3014 rotate to a state where the left end is far and the right end is near, with the cooperation of the conveying action of the conveying device 1 to the right, one of the fitting bodies 10 is urged to enter between the two seat bodies 3014. And since the distance between the right ends of the two seat bodies 3014 is less than the diameter of the fitting body 10 at this time, the fitting body 10 is temporarily blocked and stays between the two seat bodies 3014 under the blocking action of the seat bodies 3014. When the two seat bodies 3014 continue to symmetrically rotate to a state where the left end is near and the right end is far, the distance between the right ends of the two seat bodies 3014 is greater than the diameter of the fitting body 10 at this time. With the cooperation of the conveying action of the conveying device 1 to the right, the fitting body 10 is moved to the subsequent detection unit 5 on the right for subsequent detection. That is, through the opening and closing transformation action formed by the reciprocating swing of the two groups of seat bodies 3014 arranged symmetrically before and after, and in cooperation with the conveying device 1 that conveys to the right, the fitting bodies 10 can be conveyed to the subsequent detection workstations one by one at equal intervals, without manually placing the fittings one by one.

[0077] Mainly refer to Figures 6 to 9As shown in the figure, the driving mechanism includes a first bevel gear 3018 installed at the top of the rear side rotating rod 3002, and further includes a mounting frame 3019 fixedly installed on the upper surface of the rear side first bracket 3001. A first rotating shaft 3020 is rotatably arranged through the side wall of the mounting frame 3019 via a bearing. A first motor 3021 is installed on the rear side wall of the mounting frame 3019, and the output end of the first motor 3021 is fixedly connected to the first rotating shaft 3020. A second bevel gear 3022 is fixedly installed at the end of the first rotating shaft 3020 away from the first motor 3021. By starting the first motor 3021, the first rotating shaft 3020 and the second bevel gear 3022 can be driven to rotate synchronously. A second rotating shaft 3023 is rotatably connected through the mounting frame 3019 in the vertical direction via a bearing. A third bevel gear 3024 is fixedly installed at the bottom end of the second rotating shaft 3023. Synchronous wheels 3025 are respectively fixedly installed on the second rotating shaft 3023 and the front side rotating rod 3002. The two synchronous wheels 3025 are arranged corresponding to each other front and back, and a synchronous belt 3026 is sleeved on the two synchronous wheels 3025. Among them, the first bevel gear 3018 is meshed with the second bevel gear 3022, and the second bevel gear 3022 is meshed with the third bevel gear 3024. When the synchronous wheel 3025 installed on the second rotating shaft 3023 rotates, it can drive the synchronous belt 3026 to drive the synchronous wheel 3025 installed on the second bevel gear 3022 to rotate synchronously and in the same direction. At the same time, when the second rotating shaft 3023 rotates, it can synchronously drive the third bevel gear 3024 to rotate. Through the meshing action of the second bevel gear 3022, the third bevel gear 3024 can be made to rotate in the opposite direction to the first bevel gear 3018, that is, the rotating rod 3002 connected to the first bevel gear 3018 and the front side rotating rod 3002 rotate in opposite directions, that is, the two rotating rods 3002 on the front and back sides can perform circumferential rotation in opposite directions and synchronously;

[0078] Specifically, the started first motor 3021 drives the first rotating shaft 3020 and the second bevel gear 3022 to rotate, so as to drive the third bevel gear 3024 and the first bevel gear 3018 to rotate in opposite directions. At the same time, the rotating third bevel gear 3024 drives the second rotating shaft 3023 and the synchronous wheels 3025 to rotate synchronously and in the same direction, and the synchronous belt 3026 is driven to drive the other synchronous wheel 3025 to rotate synchronously and in the same direction. That is, at this time, the two synchronous wheels 3025 rotate synchronously and in the same direction, so the rotating rod 3002 directly connected to the synchronous wheel 3025 and the rotating rod 3002 directly connected to the first bevel gear 3018 rotate synchronously and in opposite directions. Thus, the purpose of the front and rear two groups of turntables 3003 rotating synchronously and in opposite directions is achieved. The present invention only uses a single driving power source to realize the stable and coordinated rotation of the front and rear corresponding two groups of seat bodies 3014 in opposite directions, thereby ensuring the coherence and accuracy of the opening and closing transformation actions of the front and rear two groups of seat bodies 3014, and improving the mechanical transmission efficiency and motion control accuracy of the entire device.

[0079] In addition, mainly referring to Figure 8 and Figure 11 As shown, a sliding component is provided between the moving plate 3006 and the limit seat 3008; the sliding component includes limit wheels 3009 that are rotatably arranged on the upper and lower sides of the inner cavity of the limit seat 3008. Limit strips 3010 are respectively installed on the upper and lower side walls of the moving plate 3006. The limit strips 3010 move horizontally along the limit wheels 3009, thereby ensuring that the moving plate 3006 can make a smoother relative movement within the limit seat 3008. Compared with the way that the moving plate 3006 directly contacts the inner wall of the limit seat 3008 and slides, it is smoother, reduces the resistance generated during the friction process, and is more conducive to extending the service life of the components.

[0080] Mainly referring to Figure 12 and Figure 13 As shown, a pushing unit 6 is provided between the intermittent conveying unit 3 and the detection unit 5. Through the setting of the pushing unit 6, the organic unity of the limiting function and the targeted pushing function is realized during the detection process of the accessory main body 10, achieving the effect of multiple uses of one component. Compared with the traditional mode of separately setting two functional mechanisms, this integrated design can significantly save the installation space inside the device, optimize the overall structural layout, and improve the space utilization rate and compactness of the device;

[0081] Specifically, the pushing unit 6 includes a stop seat 6001. A connecting frame 6006 is installed on the right side of the stop seat 6001, and the connecting frame 6006 is connected to the trough-shaped seat 5011. A second motor 6002 is provided on the connecting frame 6006. The output end of the second motor 6002 is connected to a swing arm 6003. The front and rear ends of the swing arm 6003 are respectively installed with a first push rod 6004 and a second push rod 6005. The first push rod 6004 and the second push rod 6005 are symmetrically arranged with respect to the annular seat 5006 in the front and rear directions; by setting the swing arm 6003, the first push rod 6004, and the second push rod 6005, after detecting the corresponding accessory, the accessory main body 10 can be pushed to the corresponding direction for subsequent collection by the rotation of the first push rod 6004 or the second push rod 6005. In addition, the accessory main body 10 during the detection process can be limited by means of the first push rod 6004 and the second push rod 6005, ensuring that the accessory main body 10 always stays at the detection station, and thus ensuring the accuracy of the subsequent detection results.

[0082] In addition, mainly referring to Figures 1 to 4 , Figures 12 to 14As shown in the figure, the detection unit 5 is divided into a first detection component and a second detection component. The first detection component includes an induction switch 5007, which is a commonly used induction switch on the existing market. When it moves downward and touches an object, it can transmit a signal to the PLC controller 11 for processing. The second detection component includes a first contact 5009, a second contact 5014, and a first tactile switch 5013. The second detection component also includes a third connecting arm 5010 fixedly installed on the front side wall of the third bracket 5001. A groove-shaped seat 5011 is installed on the front side of the third connecting arm 5010, and an elastic member 5012 is installed in the groove-shaped seat 5011. Among them, the first tactile switch 5013 is installed at the top end of the elastic member 5012. The first tactile switch 5013 is installed on the inner side wall of the groove-shaped seat 5011 and is disposed below the second contact 5014. When the second contact 5014 is forced to move downward, it can cause the elastic member 5012 to be compressed and trigger the first tactile switch 5013. The first tactile switch 5013 transmits the model to the PLC controller 11 for processing;

[0083] Specifically, a second mounting plate 4 is fixedly installed on the rear side wall of the conveying device 1 to provide a mounting position for the subsequent components. The first detection component and the second detection component are uniformly driven by a lifting component. The lifting component includes a third bracket 5001 fixedly installed on the second mounting plate 4. One end of a first connecting arm 5002 is installed at the top of the front side wall of the third bracket 5001. The other end of the first connecting arm 5002 is installed with a supporting seat 5003. A first cylinder 5004 is installed on the supporting seat 5003. The output end of the first cylinder 5004 is connected with a mounting plate 5005. A circular seat 5006 is fixedly installed at the bottom end of the mounting plate 5005. One end of a second connecting arm 5008 is fixedly installed on the right side wall of the mounting plate 5005. Among them, a plurality of induction switches 5007 are provided, and the plurality of induction switches 5007 are circumferentially and equidistantly arranged along the lower surface of the circular seat 5006. The first contact 5009 is installed at the other end of the second connecting arm 5008;

[0084] Specifically, by means of the downward movement of the output end of the first cylinder 5004, the mounting piece 5005, the annular seat 5006, and the proximity switch 5007 move downward synchronously. Since a number of proximity switches 5007 are circumferentially and equidistantly arranged on the annular seat 5006, when all the proximity switches 5007 contact the bottom fitting body 10, signals can be transmitted to the PLC controller 11 for processing and recording. If one of the proximity switches 5007 is not triggered, it indicates that there is an unevenness on the upper surface of the fitting body 10 corresponding to the untriggered proximity switch 5007. Thus, while detecting the height of the fitting body 10, it is also possible to detect whether the upper surface of the fitting body 10 meets the flatness requirements. At the same time, the downward movement of the mounting piece 5005 drives the second connecting arm 5008 to move downward, causing the first contact 5009 to gradually move downward and approach the second contact 5014. At this time, the detection results of the detection unit 5 for the fitting body 10 are divided into three cases:

[0085] In the first case, when the proximity switch 5007 contacts the upper surface of the fitting body 10 to achieve triggering, the first contact 5009 and the second contact 5014 contact to achieve triggering. At this time, it indicates that the fitting body 10 is a qualified product with qualified height. Specifically, when the proximity switch 5007 contacts the upper surface of the fitting body 10 to be triggered and transmits a signal to the PLC controller 11, the contact of the first contact 5009 and the second contact 5014 to achieve triggering also transmits a signal to the PLC controller 11. That is, when the proximity switch 5007 contacts the surface of the fitting body 10, the contact of the first contact 5009 and the second contact 5014 is achieved simultaneously. At this time, it indicates that the height of the fitting body 10 is qualified. The PLC controller 11 controls the second motor 6002 to start, and causes the second motor 6002 to drive the swing arm 6003, the first push rod 6004, and the second push rod 6005 to rotate counterclockwise synchronously. That is, the first push rod 6004 applies a backward thrust to the qualified fitting body 10, causing the fitting body 10 to enter the rear side of the conveying device 1 to collect the qualified fitting bodies 10.

[0086] In the second case, the inductive switch 5007 does not contact the upper surface of the fitting body 10, and the first contact 5009 contacts and triggers the second contact 5014, and the first touch switch 5013 is triggered by the second contact 5014 moving downward. At this time, it indicates that the height of the fitting body 10 is lower than the height of the qualified product. Specifically, as the inductive switch 5007 moves downward and does not contact the upper surface of the fitting body 10, the first contact 5009 has already contacted the second contact 5014, and as the mounting plate 5005 and the second connecting arm 5008 continue to move downward, the first contact 5009 prompts the second contact 5014 to move downward synchronously. At this time, the second contact 5014 triggers the first touch switch 5013 arranged below its right side. At this time, it indicates that the height of the fitting body 10 is lower than the height of the qualified fitting. At this time, the first touch switch 5013 transmits a signal to the PLC controller 11, and the PLC controller 11 controls the second motor 6002 to drive the swing arm 6003, the first push rod 6004, and the second push rod 6005 to rotate clockwise synchronously, that is, the second push rod 6005 applies a forward thrust to the unqualified fitting with a height lower than the qualified product, and prompts the fitting body 10 with a height lower than the qualified product to be output to the front side of the conveying device 1.

[0087] In the third case, while the inductive switch 5007 contacts the upper surface of the fitting body 10 to achieve triggering, the first contact 5009 does not trigger the second contact 5014. At this time, it indicates that the height of the fitting body 10 is higher than the height of the qualified product. When the mounting plate 5005 moving downward drives the annular seat 5006 and the inductive switch 5007 to trigger the upper surface of the fitting body 10 at the bottom end, the first contact 5009 does not trigger the second contact 5014, that is, it indicates that the height of the detected fitting body 10 is higher than the height of the qualified fitting. At this time, the inductive switch 5007 transmits a signal to the PLC controller 11, and the PLC controller 11 controls the second motor 6002 to drive the swing arm 6003, the first push rod 6004, and the second push rod 6005 to rotate clockwise synchronously, that is, the second push rod 6005 applies a forward thrust to the unqualified fitting with a height higher than the qualified product, and prompts the fitting body 10 with a height higher than the qualified product to be output to the front side of the conveying device 1.

[0088] Refer mainly to Figures 2 to 5 、 Figures 15 to 18 As shown in, a shunt unit 7 is arranged on the side wall of the conveying device 1. The shunt unit 7 includes a first conveying channel and a second conveying channel. The first conveying channel is arranged at the rear side of the second push rod 6005, and the second conveying channel is arranged at the front side of the first push rod 6004. The qualified fitting body 10 after detection is conveyed through the first conveying channel, and the unqualified fitting body 10 after detection is conveyed through the second conveying channel.

[0089] Refer mainly to Figure 4As shown, the first conveying channel includes a first blanking chute 7001 fixedly installed on the rear side wall of the conveying device 1. The first blanking chute 7001 is inclined downward to the rear side. First baffle plates 7002 are symmetrically installed on the left and right sides of the front side of the first blanking chute 7001. By rotating the first push rod 6004, a backward thrust can be applied to the qualified fitting body 10, prompting the qualified fitting body 10 to enter the first blanking chute 7001 to the rear side and be output to the rear side along the inclined first blanking chute 7001 for collection;

[0090] For main reference Figure 5 As shown, the second conveying channel includes a second blanking chute 7003 fixedly installed on the front side wall of the conveying device 1. The second blanking chute 7003 is inclined downward to the front side. Second baffle plates 7004 are symmetrically installed on the left and right sides of the rear side of the second blanking chute 7003. By rotating the second push rod 6005, a forward thrust can be applied to the unqualified fitting body 10, prompting the unqualified fitting body 10 to enter the inner cavity of the second blanking chute 7003.

[0091] Specifically for main reference Figure 5 、 Figure 15 and Figure 16 As shown in, a first sorting component is provided at the second blanking chute 7003; the first sorting component includes a third motor 7006 installed on the lower surface of the second blanking chute 7003. The output end of the third motor 7006 is connected to a toggle plate 7005. By starting the third motor 7006, the toggle plate 7005 can be driven to swing, and the swing amplitude of the toggle plate 7005 can be preset by the PLC controller 11. Through the guiding and blocking after the rotation of the toggle plate 7005, the conveying direction of the fitting body 10 can be adjusted. And the toggle plate 7005 is arranged in the inner cavity of the second blanking chute 7003. The connection part between the toggle plate 7005 and the output end of the third motor 7006 is located on the center line of the second blanking chute 7003 to ensure that the toggle plate 7005 can divide the second blanking chute 7003 into two guiding channels in two directions. Two screening channels 7007 are symmetrically installed on the left and right sides of the front side port of the second blanking chute 7003. Through the toggle plate 7005, the fitting body 10 sliding down at the second blanking chute 7003 can be guided to one of the screening channels 7007 for subsequent output; in addition, a chassis 8 is installed at the bottom end of the screening channel 7007. Through the chassis 8, the bottom end of the shunting unit 7 can be supported and the installation requirement of the inclined setting of the screening channel 7007 can be realized in cooperation with the height of the conveying device 1.

[0092] In addition, for main reference Figures 15 to 18As shown, a secondary sorting component is provided at each screening channel 7007. Through the secondary sorting component, it is possible to sort the accessory main body 10 with a height lower than the qualified product that has not been sorted out in the collection channel of the accessory main body 10 with a height lower than the qualified product. Similarly, it is possible to sort the accessory main body 10 with a height higher than the qualified product that has not been sorted out in the collection channel of the accessory main body 10 with a height higher than the qualified product, reducing problems such as waste of raw materials, increase in labor costs, and equipment wear caused by the mixing of unqualified products into subsequent processes, making the entire production process smoother and more efficient, reducing time waste and resource consumption in the production cycle. The secondary sorting component includes a height limit component provided above the screening channel 7007, and also includes an output component provided at the side wall of the screening channel 7007;

[0093] Refer mainly to Figure 17 and Figure 18 As shown, the height limit component includes two fixed seats 7008 fixedly installed on the upper surface of the screening channel 7007. The two fixed seats 7008 are symmetrically arranged left and right. An installation rod 7009 is provided between the two fixed seats 7008. A fixed piece 7010 is installed at the bottom end of the installation rod 7009. A second touch switch 7011 is installed on the side of the fixed piece 7010 close to the second blanking chute 7003; A height adjustment component for adjusting the height of the second touch switch 7011 is provided at the fixed seat 7008; The height adjustment component includes a screw rod 7012 rotatably connected to one of the fixed seats 7008, and also includes a smooth rod 7013 fixedly installed in the inner cavity of the other fixed seat 7008. The installation rod 7009 is slidably sleeved on the smooth rod 7013, and the installation rod 7009 is threadedly connected to the screw rod 7012;

[0094] When the accessory main body 10 with a height higher than the qualified product entering the inner cavity of the left screening channel 7007 is mixed with the accessory main body 10 with a height lower than the qualified product that has not been detected, the accessory main body 10 with a height lower than the qualified product can slide down along the inner cavity of the left screening channel 7007 and will not be blocked by the fixed piece 7010 and the second touch switch 7011 until the accessory main body 10 with a height lower than the qualified product slides down to the front side along the inner cavity of the left screening channel 7007 for output collection, that is, the inner cavity of the left screening channel 7007 is provided with the function of the accessory main body 10 with a height lower than the qualified product that has not been detected.

[0095] The output component includes a fourth bracket 7014 fixedly installed on the side wall of the screening channel 7007, and also includes a connecting bracket 7015 fixedly installed on the fourth bracket 7014. A second cylinder 7016 is installed on the connecting bracket 7015. The output end of the second cylinder 7016 is connected to a side plate 7017. One end of a cross bar 7019 is installed at the top of the side plate 7017, and the other end of the cross bar 7019 is installed with a push plate 7018. The push plate 7018 and the side plate 7017 are arranged correspondingly, and the cross bar 7019 is arranged horizontally. A first groove 7020 and a second groove 7021 are formed on the side wall of the screening channel 7007. The push plate 7018 is slidably and internally embedded in the inner cavity of the first groove 7020, and the side plate 7017 is slidably and internally embedded in the inner cavity of the second groove 7021;

[0096] When the height of the inner cavity of the right screening channel 7007 is lower than that of the fitting main body 10 of the qualified product, and there is a fitting main body 10 with a height higher than that of the qualified product that is not detected and mixed in, the fitting main body 10 with a height higher than that of the qualified product can slide down along the inner cavity of the right screening channel 7007 until it slides down to trigger the second touch switch 7011 arranged in the right screening channel 7007. The second touch switch 7011 transmits a signal to the PLC controller 11. The PLC controller 11 controls the right second cylinder 7016 to open, and prompts the right side plate 7017, cross bar 7019, and push plate 7018 to move synchronously to the right. With the push plate 7018 moving to the right, the fitting main body 10 is pushed to the right, so that the fitting main body 10 with a height higher than that of the qualified product is output and collected to the right through the second groove 7021 on the right, that is, the inner cavity of the right screening channel 7007 is provided with the function of the fitting main body 10 with a height higher than that of the qualified product that is not detected; thus, the fitting main body 10 with sorting omission in the two screening channels 7007 can be sorted and processed for the second time.

[0097] For main reference Figure 1 、 Figure 5 、 Figure 7As shown, a guide unit 9 is provided on the conveying device 1, and the guide unit 9 includes two groups of guide components symmetrically arranged front and back, and the two groups of guide components form a channel that is wide on the left and narrow on the right above the conveying device 1, and the accessories to be inspected can be guided and limited by the guide unit 9; each group of guide components includes a fourth connecting arm 9001 and a fifth connecting arm 9002 fixedly mounted on the first mounting table 2, a first guide plate 9003 is installed on the fourth connecting arm 9001, and a third guide plate 9005 is installed on the fifth connecting arm 9002, and a second guide plate 9004 is connected between the first guide plate 9003 and the third guide plate 9005; a number of accessory bodies 10 to be inspected are placed on the left side of the upper surface of the conveying device 1, and the accessory bodies 10 are limited and guided under the guidance of the first guide plate 9003, the second guide plate 9004, and the third guide plate 9005 correspondingly arranged front and back, to ensure that the subsequent accessory bodies 10 will not separate from the upper surface of the conveying device 1 from the side.

[0098] In addition, the PLC controller 11 is electrically connected to the conveying device 1, the first motor 3021, the first cylinder 5004, the induction switch 5007, the first contact 5009, the first touch switch 5013, the second contact 5014, the second motor 6002, the third motor 7006, the second touch switch 7011, and the second cylinder 7016, respectively. The PLC controller 11 can control the above-mentioned components and process related instructions. This is the prior art. The PLC controller 11 can control the above-mentioned components to achieve related functional requirements, and its model and electrical connection relationship are not limited or elaborated here.

[0099] It should be noted that there are various water pump accessories on the market.

Subsequently, defective accessories whose height is higher than that of qualified accessories can be targetedly cut again, saving production raw materials and achieving maximum utilization of defective accessories.

[0101] The working principle of a water pump accessory detection device in this embodiment for detecting accessories is as follows:

[0102] A plurality of accessory bodies 10 to be inspected are placed on the left side of the upper surface of the conveying device 1, and the accessory bodies 10 are guided by the first guide plate 9003, the second guide plate 9004, and the third guide plate 9005 correspondingly arranged at the front and rear to limit the guide, so as to ensure that the subsequent accessory bodies 10 will not be separated from the upper surface of the conveying device 1 from the side;

[0103] The cooperation between the intermittent conveying unit 3 and the conveying device 1 realizes the equidistant conveyance of the fitting main body 10 to the right one by one: The started first motor 3021 drives the first rotating shaft 3020 and the second bevel gear 3022 to rotate, so as to drive the third bevel gear 3024 and the first bevel gear 3018 to rotate in opposite directions. At the same time, the rotating third bevel gear 3024 drives the second rotating shaft 3023 and the synchronous pulley 3025 to rotate synchronously and in the same direction, and prompts the synchronous belt 3026 to drive another synchronous pulley 3025 to rotate synchronously and in the same direction. That is, at this time, the two synchronous pulleys 3025 rotate synchronously and in the same direction, so the rotating rods 3002 directly connected to the synchronous pulley 3025 and the rotating rods 3002 directly connected to the first bevel gear 3018 rotate synchronously and in opposite directions, thereby achieving the purpose of the front and rear two groups of turntables 3003 rotating synchronously and in opposite directions; The circumferentially rotating turntable 3003 prompts the dialing pin 3004 to drive the moving frame 3005 to perform a reciprocating movement of left-right transformation, so as to realize that the moving plate 3006 drives one end of the driving rod 3011 to perform a synchronous reciprocating movement. At this time, the seat body 3014 prompts the seat body 3014 to perform a reciprocating swing of forward and reverse direction transformation with the support rod 3012 as the axis, and the front and rear two groups of seat bodies 3014 perform swings of the same angle and opposite directions; When the two groups of seat bodies 3014 rotate to the state where the left end is far and the right end is near, with the cooperation of the rightward conveying action of the conveying device 1, one of the fitting main bodies 10 enters between the two seat bodies 3014 through between the two third guide plates 9005. And because the distance between the right end parts of the two seat bodies 3014 is less than the diameter of the fitting main body 10 at this time, the fitting main body 10 is temporarily blocked and stays between the two seat bodies 3014 under the blocking action of the seat body 3014. When the two seat bodies 3014 continue to symmetrically rotate to the state where the left end is near and the right end is far, at this time, the distance between the right end parts of the two seat bodies 3014 is greater than the diameter of the fitting main body 10. With the cooperation of the rightward conveying action of the conveying device 1, the fitting main body 10 is moved to the blocking seat 6001 on the right for subsequent detection. That is, through the opening and closing transformation action formed by the reciprocating swing of the front and rear symmetrically arranged two groups of seat bodies 3014, with the cooperation of the conveying device 1 that conveys to the right, the fitting main bodies 10 can be conveyed to the subsequent detection stations one by one at equal intervals without manually placing the fittings one by one;

[0104] The accessory main body 10 realizes automatic detection at the detection unit 5 and the pushing unit 6: when the accessory main body 10 moves to the right and is blocked at the left side of the stop seat 6001 at the stop seat 6001, and is kept directly below the mounting plate 5005 under the limiting action of the first push rod 6004 and the second push rod 6005; with the downward movement of the output end of the first air cylinder 5004, the mounting plate 5005, the annular seat 5006, and the induction switch 5007 move downward synchronously. And because a number of induction switches 5007 are circumferentially and equidistantly arranged on the annular seat 5006, when all the induction switches 5007 contact the accessory main body 10 at the bottom end, they can transmit signals to the PLC controller 11 for processing and recording. If one of the induction switches 5007 is not triggered, it means that there is an uneven situation on the upper surface of the accessory main body 10 corresponding to the untriggered induction switch 5007. Thus, while detecting the height of the accessory main body 10, it can also detect whether the upper surface of the accessory main body 10 meets the flatness requirements; at the same time, the downward movement of the mounting plate 5005 drives the second connecting arm 5008 to move downward, prompting the first contact 5009 to gradually move downward and approach the second contact 5014. At this time, according to whether the accessory main body 10 is qualified, it is divided into three situations: in the first situation, when the induction switch 5007 contacts the upper surface of the accessory main body 10 and is triggered, while transmitting the signal to the PLC controller 11, the first contact 5009 contacts the second contact 5014 and is triggered to also transmit the signal to the PLC controller 11, that is, when the induction switch 5007 contacts the surface of the accessory main body 10, the contact between the first contact 5009 and the second contact 5014 is realized. At this time, it means that the height of the accessory main body 10 is qualified, and the PLC controller 11 controls the second motor 6002 to start, and prompts the second motor 6002 to drive the swing arm 6003, the first push rod 6004, and the second push rod 6005 to rotate counterclockwise synchronously, that is, prompts the first push rod 6004 to apply a backward thrust to the qualified accessory main body 10, prompting the accessory main body 10 to enter the first blanking chute 7001 backward and output backward along the inclined first blanking chute 7001 for collecting the qualified accessory main bodies 10;In the second case, as the induction switch 5007 moves downward, when it has not contacted the upper surface of the fitting body 10, the first contact 5009 has already contacted the second contact 5014. As the mounting piece 5005 and the second connecting arm 5008 continue to move downward, the first contact 5009 is prompted to push the second contact 5014 to move downward synchronously. At this time, the second contact 5014 triggers the first tactile switch 5013 arranged below its right side, indicating that the height of the fitting body 10 is lower than that of the qualified fitting. At this time, the first tactile switch 5013 transmits a signal to the PLC controller 11, and the PLC controller 11 controls the second motor 6002 to drive the swing arm 6003, the first push rod 6004, and the second push rod 6005 to rotate clockwise synchronously, that is, the second push rod 6005 applies a forward thrust to the unqualified fitting with a height lower than that of the qualified product, prompting the fitting body 10 with a height lower than that of the qualified product to enter the inner cavity of the second blanking chute 7003. And at this time, the PLC controller 11 controls the third motor 7006 to swing counterclockwise to; Figure 15The position shown, that is, at this time, the accessory body 10 whose height is lower than that of the qualified product enters the inner cavity of the screening channel 7007 on the right side under the guidance of the inclined second feed chute 7003 and the toggle plate 7005, and slides along the inner cavity of the screening channel 7007 on the right side to the front side for transportation and collection; in the third case, when the downwardly moving mounting piece 5005 drives the annular seat 5006 and the induction switch 5007 to trigger the upper surface of the accessory body 10 at the bottom, the first contact 5009 does not trigger the second contact 5014, which means that the height of the detected accessory body 10 at this time is higher than the height of the qualified accessory, and the induction switch 5007 at this time transmits the signal to the PLC controller 1 1, the PLC controller 11 controls the second motor 6002 to drive the swing arm 6003, the first push rod 6004, and the second push rod 6005 to rotate clockwise synchronously, that is, the second push rod 6005 is prompted to apply a forward thrust to the unqualified accessory with a height higher than the qualified product, so that the accessory body 10 with a height higher than the qualified product enters the inner cavity of the second feeding chute 7003, and at this time, the PLC controller 11 controls the third motor 7006 to swing clockwise to a position blocking the inner cavity of the right screening channel 7007. At this time, the left screening channel 7007 is in an open state, and the accessory body 10 that is higher than the standard height slides downward through the inclined inner cavity of the left screening channel 7007 until the accessory body The body 10 moves to the second touch switch 7011 set at the outlet of the left screening channel 7007, which is triggered. At this time, the triggered second touch switch 7011 transmits a signal to the PLC controller 11, and the PLC controller 11 controls the second cylinder 7016 on the left to open and move to the left, so as to prompt the side plate 7017, the cross bar 7019 and the push plate 7018 to move to the left synchronously. Under the pushing action of the push plate 7018, the accessory body 10 higher than the standard height is discharged to the left through the second trough body 7021 on the left, that is, the unqualified accessories higher than the qualified products are output and collected to the left; that is, after detection, the qualified accessory body 10 enters the first discharge trough 7001 backwards. The unqualified accessory bodies 10 (including products with heights lower than the qualified ones and products with heights higher than the qualified ones) are all output to the front side and enter the second discharge chute 7003. Subsequently, the accessory bodies 10 with heights lower than the qualified ones are output to the front side and collected through the screening channel 7007, and the accessory bodies 10 with heights higher than the qualified ones are output to the side through the side plates 7017 in the open state. Therefore, there is no need to perform secondary sorting and differentiation of unqualified defective accessories in the future. The accessory height detection and automatic sorting of unqualified accessories can be realized at one time. The defective accessories with heights higher than the qualified ones can be cut again in a targeted manner in the future, saving production raw materials and realizing the maximum utilization of defective accessories.

[0105] In order to further ensure that unqualified fitting bodies 10 are not missed during sorting, this application is provided with a secondary sorting function: when the height of the fitting bodies 10 entering the inner cavity of the left screening channel 7007 is higher than that of the qualified products and there are fitting bodies 10 with a height lower than that of the qualified products that have not been detected mixed in, the fitting bodies 10 with a height lower than that of the qualified products can slide down along the inner cavity of the left screening channel 7007 and will not be blocked by the fixing piece 7010 and the second touch switch 7011 until the fitting bodies 10 with a height lower than that of the qualified products slide down along the inner cavity of the left screening channel 7007 to the front side for output collection, that is, the inner cavity of the left screening channel 7007 is provided with the function of sorting out the fitting bodies 10 with a height lower than that of the qualified products that have not been detected; similarly, when the height of the fitting bodies 10 entering the inner cavity of the right screening channel 7007 is lower than that of the qualified products and there are fitting bodies 10 with a height higher than that of the qualified products that have not been detected mixed in, the fitting bodies 10 with a height higher than that of the qualified products can slide down along the inner cavity of the right screening channel 7007 until they slide down to trigger the second touch switch 7011 provided in the right screening channel 7007. The second touch switch 7011 transmits a signal to the PLC controller 11, and the PLC controller 11 controls the right second cylinder 7016 to open and prompts the right side plate 7017, the cross bar 7019, and the push plate 7018 to move synchronously to the right. With the push plate 7018 moving to the right, the fitting body 10 is pushed to the right, and the fitting body 10 with a height higher than that of the qualified products is output and collected to the right through the right second groove body 7021, that is, the inner cavity of the right screening channel 7007 is provided with the function of sorting out the fitting bodies 10 with a height higher than that of the qualified products that have not been detected; thus, the fitting bodies 10 with sorting omissions in the two screening channels 7007 can be sorted again;

[0106] In addition, when detecting fitting bodies 10 with different batches and different heights, the reciprocating moving stroke length of the first cylinder 5004 is adjusted through the PLC controller 11 to adapt it to the detection of the standard height of the fitting bodies 10 in this batch, ensuring that when the first cylinder 5004 drives the induction switch 5007 and the first contact 5009 to descend to the lowest end of this stroke, it just accurately touches the upper surface of the fitting body 10 with the standard height and is triggered; in addition, for fitting bodies 10 with different batches and different heights, the height of the second touch switch 7011 can be adjusted specifically, that is, by rotating the driving screw 7012, at this time the mounting rod 7009 moves up and down along the screw 7012 and the optical rod 7013, thereby realizing the adjustment of the height where the fixing piece 7010 and the second touch switch 7011 are located, that is, ensuring that when detecting fitting bodies 10 with different batches and different heights, the fitting bodies 10 with a height higher than the standard height can reach the height to trigger the second touch switch 7011 for sorting;

[0107] In summary, firstly, this equipment realizes an automated inspection process. Compared with the traditional manual inspection method, it guides, limits and transports the inspected accessories one by one through specific components, and can automatically and orderly deliver the accessories to the inspection area, meeting the needs of large-scale and batch inspection tasks, greatly improving the inspection efficiency, effectively ensuring the overall inspection efficiency and capacity improvement, reducing the errors and limitations caused by manual operation, and enhancing the accuracy and stability of inspection; secondly, with the help of a series of components, the conversion from circular motion to horizontal reciprocating motion is realized, and the related components are driven to rotate or swing in a stable and coordinated manner, which not only ensures the synchronization and continuity of the movements, but also avoids the energy loss caused by frequent switching of the driving force direction, reduces the system operation cost, and extends the service life of the components. At the same time, it provides reliable guarantee for long-term, efficient and stable operation, and improves the mechanical transmission efficiency and motion control accuracy; in addition, in terms of detection accuracy and classification collection, it can accurately Refined detection distinguishes three situations: accessories that meet height requirements, accessories that are higher than the qualified height, and accessories that are lower than the qualified height. Corresponding collection systems are set up in a targeted manner to achieve integrated detection and classification, save secondary sorting and processing procedures, and adapt to the detection needs of accessories of different heights in different batches through adjustable components, improve equipment flexibility and adaptability, expand the scope of use and detection efficiency, and can distinguish and collect unqualified accessories in a high and low detailed manner, which is helpful to formulate reasonable reuse plans, improve the utilization rate of raw materials, and reduce scrap rate and production costs. In addition, it also has the function of secondary sorting of unqualified products, which can avoid sorting omissions and reduce various problems caused by unqualified products mixed into subsequent links, making the production process smoother and more efficient, reducing time and resource consumption, and improving the reliability, integrity and intelligence level of the entire sorting system, optimizing the overall structural layout, and improving the space utilization and compactness of equipment, providing sufficient guarantee for the quality inspection of water pump accessories.
