Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically a high-efficiency bar testing device. Background Technology

[0002] Bar stock is a key raw material for parts manufacturing, and the market demand is huge. However, bar stock produced by machine tools may have quality defects such as cracks and scratches on its surface, which can significantly affect the physical properties of the product. To ensure the quality of products leaving the factory, defective bar stock must be identified and recycled using professional testing equipment.

[0003] Currently, high-efficiency bar inspection equipment is equipped with multiple inspection modules, capable of detecting indicators such as length, end face defects, diameter, chamfer dimensions, and bar body defects, and also has a defective product recycling function. However, existing equipment has significant shortcomings in the defective product recycling process. For example, mixing all defective bars for recycling leads to the need for manual sorting later, resulting in low processing efficiency. Alternatively, using complex sensor systems in conjunction with handling mechanisms to immediately control the handling mechanism to move the bars to the corresponding recycling area after detecting defects significantly increases recycling costs and reduces work efficiency. Moreover, sensors are prone to misjudgment under continuous high-frequency use, leading to sorting errors and affecting the stability and accuracy of recycling.

[0004] The research objective of this invention is to design a high-efficiency bar material testing device to address the problems existing in the prior art. Utility Model Content

[0005] This invention provides a high-efficiency bar testing device that can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A high-efficiency bar testing device, comprising:

[0008] The testing facility includes sequentially arranged feeding stations and several testing modules for defect detection of the bars.

[0009] A feeding mechanism is used to sequentially input several bars into the feeding station;

[0010] The discharge mechanism includes several movable parts arranged side by side with several fixed parts and forming discharge stations between them, a qualified receiving device and several recycling receiving devices located below the several discharge stations respectively, the several discharge stations are arranged in a horizontal sequence, the several recycling receiving devices correspond to several detection modules respectively, and the several movable parts are driven by the discharge driving device to move to abut against the fixed parts to close the discharge station or to be spaced apart from the fixed parts to open the discharge station;

[0011] A plurality of moving mechanisms are used to move the bars sequentially along the plurality of detection modules and the plurality of discharge stations.

[0012] Furthermore, the plurality of the transfer mechanisms include a detection and transfer mechanism, a detection and shifting mechanism, and a discharge and shifting mechanism. The detection and transfer mechanism includes a plurality of transfer grippers that are arranged sequentially and driven together by a transfer drive device to move up and down and laterally. The detection and shifting mechanism includes a plurality of detection and shifting ends that are driven together by a first shifting drive device to move up and down and forward and backward. The discharge and shifting mechanism includes a plurality of discharge and shifting ends that are driven together by a second shifting drive device to move up and down and forward and backward. The plurality of transfer grippers, detection and shifting ends, and discharge and shifting ends are used to transfer or shift the bar material to move step by step along the plurality of detection modules and the plurality of discharge stations.

[0013] Furthermore, the detection mechanism also includes two sets of conveying rollers and two sets of rotating rollers that are staggered together. Each set of conveying rollers includes conveying rollers that are side by side and abut each other to form a conveying station. Each set of rotating rollers includes rotating rollers that are side by side and abut each other to form a rotating station. The two rotating rollers are driven to rotate by a rotating drive device to rotate the bar on the rotating station. The number of detection shifting ends is set to four and is used to shift the bar from the rear end of the two conveying stations and the two rotating stations to the front end.

[0014] Furthermore, the plurality of discharge stations include, in sequence from back to front, qualified discharge stations, end-face defect discharge stations, end-diameter defect discharge stations, middle-diameter defect discharge stations, length defect discharge stations, chamfer defect discharge stations, and bar body defect discharge stations. A qualified receiving device and a plurality of recycling receiving devices are distributed in sequence from back to front, and the plurality of recycling receiving devices include, in sequence from back to front, end-face defect recycling receiving devices, end-diameter defect recycling receiving devices, middle-diameter defect recycling receiving devices, length defect recycling receiving devices, chamfer defect recycling receiving devices, and bar body defect recycling receiving devices. The number of discharge shifting ends is set to six and is used for lifting and lateral movement corresponding to the rear end of the last six discharge stations to shift the bar material from back to front.

[0015] Furthermore, the feeding mechanism includes a hopper and an anti-jamming device. The hopper has a forward-sloping, downward-extending guide member inside, a discharge port extending through the front bottom, a baffle member on the bottom side that passes through the lower end of the guide member, is positioned above the discharge port, and is driven to move laterally back and forth by a clearance drive device, and a through hole at the front. The top of the lower end of the guide member is recessed and forms a clearance angle with the front end of the baffle member that matches the cross-section of a bar. The anti-jamming device includes a device that passes through the through hole and is driven by a pusher. A pusher is driven to move parallel to the upper side of the guide member at intervals. The feeding station is provided with a feeding seat with a feeding slot with a top recess and a groove gap corresponding to the discharge port. Several bars are horizontally arranged in the hopper and stacked on the guide member. The pusher moves parallel to the upper side of the guide member at intervals, pushing most of the bars upward so that a small portion of the bars within the clearance angle are in a loose state. Then, the partition moves backward to make room so that one bar within the clearance angle is discharged through the discharge port into the feeding slot.

[0016] Furthermore, the front end of the partition member is provided with a plurality of partition teeth that penetrate the lower end of the guide member and are inclined downwards with the front end facing forward. The plurality of partition teeth are spaced apart from the lower end of the guide member. The top of the lower end of the guide member is inclined downwards and recessed, forming the clearance angle with the plurality of partition teeth. The number of through holes is provided and distributed at intervals on the left and right. The telescopic ends of the pusher and the pusher drive device are inclined at the same angle as the guide member. The rear end of the pusher member is provided with a plurality of pusher teeth that are spaced apart on the left and right and extend backwards through the plurality of through holes. The rear end of the partition member extends upwards and then folds backwards, and its bottom is slidably connected to the bottom of the hopper. The clearance drive device includes a telescopic cylinder provided on the outer wall of the hopper and whose telescopic end is connected to the rear end of the partition member through a connecting rod assembly, and a plurality of buffer springs connecting the left and right ends of the connecting rod assembly and the left and right outer sides of the hopper.

[0017] Furthermore, the front and rear inner walls of the hopper and the top of the guide are respectively recessed with a number of corresponding front adjustment grooves, a number of rear adjustment grooves, and a number of bottom adjustment grooves. An adjustment plate extending forward and backward is provided inside the hopper. The front and rear ends and the lower end of the adjustment plate are used to be inserted into the corresponding front adjustment grooves, rear adjustment grooves, and bottom adjustment grooves to adjust the width of the storage area of ​​the hopper.

[0018] Furthermore, the side wall of the adjusting plate is provided with several material distribution partitions with the same inclination angle as the guide and spaced vertically. The material distribution partitions divide the storage area into several storage layers with vertical spacing for storing single rows of bars. The front ends of the lower material distribution partitions are respectively provided with flexible parts that move vertically. The front ends of the flexible parts are distributed in an arc shape from bottom to top and form a gradually increasing width between them and the inner wall of the hopper, corresponding to the pushing area of ​​the pusher. The distance between the uppermost flexible part and the front ends of the upper material distribution partitions and the front wall of the hopper is adapted to the outer diameter of a single bar. When the pusher moves upward to push the bars in the pushing area upward, the upward movement of the bars is flexibly buffered by the flexible parts.

[0019] Furthermore, the feeding mechanism also includes a filling device. The left and right side walls of the hopper are respectively recessed with vertically extending grooves, and the rear wall is a detachable, vertically sliding rear sealing plate inserted between the two grooves. Several rear adjustment grooves are provided on the inner wall of the rear sealing plate. The filling device includes a hopper at the lower front end for inserting several rear adjustment grooves and at the left and right ends of the front end for sliding vertically inserted between the two grooves. The front wall of the hopper is provided with a filling port corresponding to several storage layers, and the inner bottom is inclined forward and downward to form a guide surface connecting the filling port.

[0020] Furthermore, the feed trough extends to the left and right and is recessed with a clamping groove. A fixed top material component and a movable top material component are respectively inserted through the left and right sides. The fixed top material component and the movable top material component are driven to move laterally to the left and right by the adjustment drive device and the movable drive device, respectively. After the fixed top material component moves laterally to the set position and the bar falls into the feed trough, the movable top material component pushes the bar to abut against the fixed top material component so that the middle part of the bar corresponds to the clamping groove.

[0021] The beneficial effects of this utility model are:

[0022] 1. Through the corresponding coordination between several sequentially distributed detection modules and several discharge stations, and the transportation by a transfer mechanism, several bars are sequentially sorted and moved step by step along the detection modules and discharge stations. This allows the control system to open the corresponding discharge station when no defects are detected by the detection modules (i.e., no defects in the bars), causing the corresponding numbered bars to fall and be discharged to the qualified receiving device. This ensures that qualified bars are automatically discharged in a concentrated manner. Conversely, when a defect is detected by a detection module (i.e., a defect exists in the bars), the control system opens the corresponding discharge station, causing the corresponding numbered bars to fall and be discharged to the corresponding recycling receiving device. This ensures that bars with different defects fall automatically to the corresponding recycling receiving devices for centralized collection, achieving automatic classification and recycling of unqualified bars. This discharge layout concentrates the classification and discharge of qualified and unqualified bars in the next process of the detection mechanism, not only without affecting the detection efficiency of the bars but also allowing for efficient processing. The system determines which bar is qualified or unqualified based on its serial number before unloading. This eliminates the need for manual intervention or numerous sensors, enabling precise detection and sorting of bars. This significantly reduces the cost of bar detection and sorting, and greatly improves sorting efficiency. Furthermore, based on this unloading layout, several horizontally distributed unloading stations, formed by fixed and movable components, allow for rapid control of the unloading stations' opening and closing during the bar transport process. This control enables the bars to fall or continue moving to the next stage by the transport mechanism. This unloading method not only ensures the accurate opening of the unloading station corresponding to the bar's serial number, delivering it to the appropriate receiving device, but also allows for quick resetting of the movable components to close the unloading station after unloading, without affecting the movement of the next bar. This prevents the unloading from disrupting the overall operating rhythm of the unloading mechanism, ensuring the overall efficiency of the testing equipment.

[0023] 2. The feeding mechanism can achieve the following feeding method: the pusher moves parallel to the upper side of the guide and pushes most of the bars upward to loosen a small portion of the bars within the clearance angle. The partition moves backward to allow one bar within the clearance angle to be fed into the feeding slot through the discharge port, completing the feeding of one bar. This process is repeated to sequentially input several bars. By adding the clearance angle and anti-jamming device, the mechanism effectively loosens excessively stacked bars in the hopper. During feeding, the pusher first separates the small portion of bars within the clearance angle from the majority of the bars, ensuring that the small portion is loose and easy to discharge. Then, the partition moves backward to allow the bars to roll down one by one. This method precisely ensures that only one bar is discharged from the hopper at a time, preventing multiple bars from being squeezed into the discharge port and causing blockage. It ensures unobstructed discharge during each feeding and that the gap in the slot corresponds to the feeding. The design of the feed chute ensures that only one bar can be fed at a time. Even if bars are stacked in the feed chute, they can only fall one at a time. Only after the first bar enters the subsequent detection module and the feed chute is emptied can the second bar fall. This achieves the accuracy and stability of the feeding mechanism in sequentially feeding multiple bars into the feed chute, avoiding situations where multiple bars are fed or no bars are fed, which would disrupt the bar sorting. This, in turn, improves the stability of the subsequent detection and discharge mechanisms in sorting, detecting, and classifying the bars, thus enhancing the overall station stability of the high-efficiency bar detection equipment and ensuring work efficiency.

[0024] 3. By adding several flexible layers arranged in an arc shape from bottom to top on the rear and upper sides of the pushing area, the upward movement of the pushing component and the bar stock within the pushing area can be buffered by these flexible layers. Furthermore, the gradually increasing width of the pushing area from top to bottom increases the distance between the bottommost flexible layer and the pushing component, preventing interference. This also ensures that only a small portion of the bar stock is stacked within the pushing area during each push, while the majority of the bar stock is arranged in single rows within several storage layers and supported by several dividing partitions, thus significantly reducing the number of bar stock stacked within the pushing area. The quantity is reduced, the pushing pressure of the pusher is reduced, the number of bars pushed by the pusher is reduced, and the movement of a small number of bars is flexibly restricted by several flexible parts. This restricts the upward movement of a small number of bars to a limited pushing area, so as to avoid collision space between small numbers of bars. This allows the small number of bars to move upward stably as a whole after being pushed by the high frequency and high speed of the pusher. This avoids the situation where frequent collisions between several bars increase the probability of damage. In other words, while ensuring the efficiency of bar feeding one by one, the pusher can work at a high frequency and high speed to ensure the safety and stability of the bars in the hopper when pushed upward by the pusher.

[0037] Example 1

[0038] Reference Figure 1-9 As shown, a high-efficiency bar testing device includes:

[0039] The inspection mechanism 1 includes a feeding station (11) arranged in sequence and a number of inspection modules for defect detection of the bar stock. Specifically, the number of inspection modules includes a number of inspection stations arranged in sequence and a number of inspection devices for defect detection of the bar stock at the number of inspection stations 12. The number of inspection devices are all vision inspection devices, and their defect acquisition units are industrial cameras. The specific structure of the vision inspection device can be referred to the prior art and is not the focus of this invention, so it will not be described in detail here.

[0040] Feeding mechanism 2 is used to sequentially input several bars into the feeding station 11. Specifically, the bars can be cemented carbide, magnetic materials, etc.

[0041] The discharge mechanism 3 includes a plurality of movable parts 32 arranged side by side with a plurality of fixed parts 31 and forming discharge stations between them, a qualified receiving device 34 located below a plurality of discharge stations 33, and a plurality of recycling receiving devices. The plurality of discharge stations 33 are arranged in a horizontal sequence, and the plurality of recycling receiving devices 35 correspond to a plurality of detection devices 13. The plurality of movable parts 32 are driven by the discharge driving device 321 to move to abut against the fixed parts 31 to close the discharge station 33 or to be spaced apart from the fixed parts 31 to open the discharge station 33.

[0042] A plurality of moving mechanisms 4, through which a plurality of bars are moved sequentially along a plurality of inspection stations 12 and a plurality of discharge stations 33; specifically, a plurality of sets of high-efficiency bar inspection equipment can be arranged side by side, such as Figure 1 As shown, two sets of sheet metal testing equipment are arranged side by side on the base.

[0043] The above structure, through the corresponding cooperation between several sequentially distributed inspection stations and several discharge stations, and the transportation by the transfer mechanism 4, achieves the effect of sequentially sorting several bars and moving them step by step along several inspection stations 12 and several discharge stations 33. This allows the control system to control the corresponding discharge station 33 to open when the inspection devices 13 do not detect defects (i.e., the bars are defect-free), causing the corresponding numbered bars to fall and be discharged to the qualified receiving device 34, thus automatically and centrally discharging qualified bars. When the inspection device 13 detects a defect (i.e., the bars have a certain defect), the control system to open the corresponding discharge station 33 to cause the corresponding numbered bars to fall and be discharged to the corresponding recycling receiving device 35, causing bars with different defects to automatically fall into the corresponding recycling receiving devices for centralized recycling, achieving automatic classification and recycling of unqualified bars. This discharge layout concentrates the classified discharge of qualified and unqualified bars in the next process after the inspection mechanism 1, without affecting the inspection mechanism 1. The improved efficiency of bar inspection allows for precise bar inspection and sorting without the need for manual intervention or numerous sensors. This significantly reduces the cost of bar inspection and sorting, and greatly improves sorting efficiency. Furthermore, the horizontally distributed discharge stations formed by several fixed components 31 and movable components 32 enable rapid control of the discharge stations during bar handling by the transfer mechanism 4. This allows for quick control of the discharge stations' opening and closing, controlling the bar's descent or continued movement to the next level. This discharge method ensures accurate opening of the discharge station corresponding to the bar's serial number, discharging it to the appropriate receiving device. After bar discharge, the movable component 32 can be quickly reset to close the discharge station without affecting the movement of the next bar, thus preventing the discharge from impacting the overall operating rhythm of the discharge mechanism 3 and ensuring the overall efficiency of the inspection equipment.

[0044] To improve detection efficiency, the plurality of detection stations 12 include a plurality of static stations arranged sequentially from back to front and a plurality of rotary stations arranged sequentially from back to front. The feeding station 11, the plurality of static stations, the plurality of rotary stations, and the plurality of discharging stations 33 are arranged sequentially from back to front, and the plurality of rotary stations and the plurality of discharging stations 33 are arranged sequentially from front to back. The plurality of transfer mechanisms 4 include a detection and handling mechanism 41, a detection and shifting mechanism 42, and a discharging and shifting mechanism 43. The detection and handling mechanism 41 includes a plurality of handling grippers 412 arranged sequentially from front to back, corresponding to the static stations and driven together by the handling drive device 411 to lift and move laterally. The detection and shifting mechanism 42 includes a plurality of detection shifting ends 422 tilted to correspond to the rotary stations and driven together by the first shifting drive device 421 to lift and move forward and backward. The discharging and shifting mechanism 43 includes a plurality of discharging shifting ends 432 tilted to correspond to the plurality of discharging stations 33 and driven together by the second shifting drive device 431 to lift and move forward and backward. The above structure, through a linear arrangement of feeding stations 11, several static stations, several rotary stations, and several discharging stations 33, enables several bars to move linearly and sequentially after feeding, significantly shortening the transport stroke during the inspection process. In particular, while meeting the inspection requirements, several rotary stations and several discharging stations are specially connected sequentially, and the multiple sequentially arranged bars are pushed forward synchronously and sequentially by several inspection shifting ends 422 and several discharging shifting ends 432, thereby maximizing the movement stroke of the bars, minimizing the drive stroke of the inspection shifting mechanism 42 and the discharging shifting mechanism 43, improving the inspection cycle of the high-efficiency bar inspection equipment, and increasing the inspection efficiency.

[0045] To improve defect detection, the static workstations include an end face inspection workstation 121, an end diameter inspection workstation 122, a middle diameter inspection workstation 123, and a length inspection workstation 124. The inspection mechanism 1 also includes two sets of conveying rollers 14 and two sets of rotating rollers 15 that are staggered together. Each set of conveying rollers 14 includes conveying rollers that are side by side and abut each other, forming a conveying workstation 141. Each set of rotating rollers 15 includes rotating rollers that are side by side and abut each other, forming a rotating workstation. The two rotating rollers are driven to rotate by a rotation drive device 16 to rotate the bar on the rotating workstation. Specifically, the rotation drive device 16 can be a rotary motor, and the two rotation stations are a bar body detection station 126 and a chamfer detection station 125 distributed front and rear, respectively. The plurality of detection devices 13 include an end face detection device 131, an end diameter detection device 132, a middle diameter detection device 133, a length detection device 134, a chamfer detection device 135, and a bar body detection device 136 distributed from back to front. The number of detection shifting ends 422 is set to four and is used for lifting and lateral movement corresponding to the rear ends of the two conveying stations 141 and the two rotation stations to shift the bar material from back to front. Therefore, based on the dimensional defect detection of the bar material, such as end face inspection, diameter inspection at both ends, diameter inspection at the middle, and length inspection, the staggered arrangement of the conveyor roller group 14 and the rotating roller group 15 allows the chamfering and bar body defects of the bar material to be detected by the chamfering detection device 135 and the bar body detection device 136 respectively as the bar material passes through the chamfering detection station 125 and the bar body detection station 126 and is driven to rotate by the rotating roller group 15. This improves the completeness of the bar material defect detection, enhances the defect detection effect, and improves the quality of the bar material leaving the factory after inspection and screening.

[0046] When the bar stock qualification rate is high, setting the corresponding qualified bar stock discharge station at the front end means that a large number of qualified bars must pass through more and more other discharge stations before being discharged. This causes the fixed parts 31 and moving parts 32 of other discharge stations to be subjected to frequent friction, resulting in a reduced lifespan. Therefore, in order to improve the service life of the discharge mechanism 3, the discharge stations 33 include, from back to front, a qualified discharge station 331, an end face defect discharge station 332, an end diameter defect discharge station 333, a middle diameter defect discharge station 334, a length defect discharge station 335, and a chamfer defect discharge station 336. The bar body defect discharge station 337, the qualified receiving device 34 and the several recycling receiving devices 35 are distributed sequentially from back to front, and the several recycling receiving devices 35 include the end face defect recycling receiving device 351, the two end diameter defect recycling receiving device 352, the middle diameter defect recycling receiving device 353, the length defect recycling receiving device 354, the chamfer defect recycling receiving device 355, and the bar body defect recycling receiving device 356, which are distributed sequentially from back to front. The number of discharge shifting ends 432 is set to six and is used for lifting and lateral movement corresponding to the rear end of the six discharge stations 33 to shift the bar material from back to front. The above structure distributes the qualified discharge station 331 behind all the defective discharge stations. This ensures that, when the bar material qualification rate is high, the qualified bars, after passing inspection, immediately discharge from back to front into the qualified discharge station 331. Since the qualified discharge station 331 is open at this time, this arrangement prevents the discharge of qualified bars from causing friction to the fixed parts 31 and movable parts 32 of the defective discharge station in front, as well as to the fixed parts 31 and movable parts 32 of the qualified discharge station 331. For the small number of defective bars, they will only occasionally cause friction to the fixed parts 31 and positioning parts behind the qualified discharge station 331 and the corresponding defective discharge station. Therefore, by rearwardly arranging the qualified discharge station 331, the wear on the fixed parts 31 and movable parts 32 of each discharge station during the bar material sorting and discharge process can be greatly reduced, thereby increasing the overall service life of the discharge mechanism 3 and improving the sorting and discharge efficiency.

[0047] Specifically, the end face defects of the bar stock include missing material, cracks, and lack of luster, and the accuracy must be around 0.015mm. The chamfer defects of the bar stock include chamfer dimensions, notches, reverse orientation, missing parts, and scratches, and the accuracy must be around 0.025mm. The bar body defects of the bar stock include threads, holes, scratches, cracks, color differences, dirt, clamping marks, rust spots, and corrosion, and the accuracy must be around 0.05mm. The length accuracy of the bar stock must be around 0.05mm. The diameters at both ends and the middle of the bar stock must be around 0.5μm.

[0048] The existing feeding mechanism 2 controls the sequential falling of several bars by stacking them in a container and then opening or closing the outlet using a telescopic baffle. However, this design causes the bottom bars to be squeezed by the large number of bars above them, resulting in multiple bars falling when the baffle retracts and the outlet opens, or multiple bars being squeezed and blocked from falling, leading to gaps in the bar sorting and causing confusion in subsequent inspection work, thus affecting inspection efficiency. Therefore, to ensure the stability of sequentially inputting several bars into the feeding station 11, the feeding mechanism 2 includes a hopper 21 and an anti-jamming device 22. The hopper 21 has a guide 23 that extends downwards and tilts forward, a discharge port 211 that penetrates through the bottom front, a baffle 24 that penetrates through the lower end of the guide 23 and is positioned above the discharge port 211 and is driven to move back and forth by a clearance drive device 25, and a through hole 212 that penetrates through the front. The bottom top of the guide 23 is recessed. The anti-jamming device 22 includes a pusher 221 that passes through the through hole 212 and is driven by the pusher drive device 222 to move parallel to the upper side of the guide member 23 at intervals. The feeding station 11 is provided with a feeding seat 111 with a feeding groove 112 with a top recess and a slot gap corresponding to the discharge port 211. Several bars are horizontally arranged in the hopper 21 and stacked on the guide member 23. 3. The above structure enables the feeding mechanism 2 to achieve the following feeding method: the pusher 221 moves upward parallel to the upper side of the guide 23, pushing most of the bars upward so that a small portion of the bars within the clearance angle 26 are in a loose state. The partition 24 moves backward to make room so that one bar within the clearance angle 26 is fed into the feeding groove 112 through the discharge port 211, completing the feeding of one bar. The above action is repeated to complete the sequential input of several bars.By adding the clearance angle 26 and the anti-jamming device 22, the excessively stacked bars in the hopper 21 are loosened. During feeding, the pusher 221 first separates a small portion of the bars within the clearance angle 26 from the majority of the bars, ensuring that the small portion of bars within the clearance angle 26 is loose and easy to discharge. Then, the partition 24 moves backward to allow the bars to roll down one by one. This feeding method accurately ensures that only one bar is discharged from the hopper 21 at a time, preventing multiple bars from being squeezed into the discharge port 211 and causing blockage. This ensures that the discharge port 211 is unobstructed every time, and the gap between the slots corresponds to the discharge... The feeding trough 112 of the material inlet 211 is designed so that it can only hold one bar at a time. Even if the bars stacked in the material inlet 211 can only fall one by one, the latter can only fall after the former enters the subsequent inspection station and the feeding trough 112 is emptied. This achieves the accuracy and stability of the feeding mechanism 2 feeding several bars into the feeding trough 112 one by one, avoiding the situation where multiple bars are fed or no bars are fed, which would disrupt the bar sorting. This improves the stability of the subsequent inspection mechanism 1 and the discharge mechanism 3 in sorting, inspecting and sorting the bars, and improves the overall station stability of the high-efficiency bar inspection equipment, ensuring work efficiency.

[0049] Since the hopper 21 can hold approximately 1800 bars, the pushing force required to move them is relatively large. Therefore, to improve the driving stability of the anti-jamming device 22, the front end of the baffle 24 is provided with several baffle teeth 241 that penetrate the lower end of the guide 23 and are inclined downwards with their front ends facing forward. The baffle teeth 241 are spaced apart from the lower end of the guide 23. The top of the lower end of the guide 23 is inclined downwards and recessed, forming the clearance angle 26 with the baffle teeth 241. The number of through holes 212 is several and distributed at intervals on the left and right. The pusher 221 and the pusher... The telescopic end of the drive device 222 is inclined at the same angle as the guide member 23. The rear end of the pusher member 221 is provided with several pusher teeth 2211 that are spaced apart on the left and right and extend backward through several through holes 212. The rear end of the partition member 24 extends upward and then folds backward, and its bottom is slidably connected to the bottom of the hopper 21. The clearance drive device 25 includes a telescopic cylinder 252 located on the outer wall of the hopper 21 and whose telescopic end is connected to the rear end of the partition member 24 through a connecting rod assembly 251, and several buffer springs 253 connecting the left and right ends of the connecting rod assembly 251 and the left and right outer sides of the hopper 21. Thus, through the cooperation between the several pusher teeth 2211 spaced left and right and the several through holes 212, the contact area between the pusher 221 and the bar can be increased without the bar detaching from the hopper 21. This increases the pushing force of the pusher 221 on the bars and improves the stability of the pusher 221 pushing the bars upward along the guide 23. At the same time, since the lower end of the guide 23 itself bears a large load and all the bars are stacked on the guide 23, in order to avoid the partition 24 from collapsing with the guide during extension and retraction... The collision of component 23 weakens the structural strength of the lower end of the guide component 23 or causes damage to several bars. By setting several buffer springs 253 and setting a gap between several of the partition teeth 241 and the lower end of the guide component 23, it is possible to avoid the partition component 24 extending too fast and colliding with the lower end of the guide component 23, which would cause the structural strength of the guide component 23 to decrease and break. It is also possible to avoid the impact of the partition component 24 resetting on the guide component 23 and several bars, thereby improving the service life of the partition component 24 and the guide component 23.

[0050] To improve the adaptability of the hopper 21, the front and rear inner walls of the hopper 21 and the top of the guide member 23 are respectively recessed with a number of corresponding front adjustment grooves 213, a number of rear adjustment grooves 214, and a number of bottom adjustment grooves 231. The hopper 21 is provided with front and rear extending adjustment plates 27. The front and rear ends and the bottom end of the adjustment plates 27 are used to be inserted into the corresponding front adjustment grooves 213, rear adjustment grooves 214, and bottom adjustment grooves 231 to adjust the width of the storage area 215 of the hopper 21. By adding several front adjustment slots 213, several rear adjustment slots 214, and several bottom adjustment slots 231, the storage width of the hopper 21 can be adjusted by the installation position of the adjustment plate 27 to accommodate different bar lengths, greatly improving the storage adaptability of the hopper 21. At the same time, it ensures the stable stacking of several bars in the hopper 21, avoiding the situation where the bars deviate after the pusher 221 pushes several bars up and cannot be aligned with the discharge port 211, making it difficult to discharge the bars. This further ensures the stability of the hopper 21 discharging bars one by one.

[0051] To improve the stability of the transfer mechanism 4 in transferring the bar stock, the feed chute 112 extends laterally and is recessed with a clamping groove 1121. A fixed top material member 17 and a movable top material member 18 are respectively inserted through the left and right sides. The fixed top material member 17 and the movable top material member 18 are driven to move laterally left and right by the adjustment drive device 171 and the movable drive device 181, respectively. A centering positioning station 127 for centering the bar stock is also provided between the end face detection station 121 and the two end diameter detection stations 122. The number of transporting jaws 412 is set to six, and the second transporting jaw 412 from back to front is also driven to rotate by a steering drive device 44. The six transporting jaws 412 respectively transport the bar stock between adjacent feed stations 11, static stations, centering positioning stations 127, and the rear conveying station 141. Specifically, the adjustment drive device 171 and the movable drive device 181 can be existing drive devices such as cylinders or electric cylinders. The above structure enables the transfer of the bar stock according to its properties. The fixed top member 17 is moved laterally to a set position. After the bar falls into the feed chute 112, the movable top member 18 pushes the bar inward to abut the fixed top member 17, so that the middle of the bar corresponds to the clamping groove 1121. In this way, when the last transport claw 412 clamps the bar through the clamping groove 1121, it can accurately grasp the middle of the bar, which is beneficial to the accuracy of subsequent testing. Thus, the fixed top member 17 and the movable top member 18 increase the efficiency of the test. This design ensures the stability of the rearmost transport gripper 412 in holding and transporting the middle of the bar. Simultaneously, the addition of the centering positioning station 127 allows the transport gripper 412, after gripping the bar at the end-face inspection station 121 from the rear, to rotate 90 degrees and transport it to the centering positioning station 127 for centering. This ensures that the front transport gripper 412 can still stably grip the middle of the bar when it moves backward to grip the rotated bar, thereby ensuring the accuracy of subsequent inspection work.

[0052] To facilitate the handling of the hopper 21, the hopper 21 is installed on the top of the trolley 5. The rear side of the discharge mechanism 3 is provided with a sampling inspection mechanism 6. The sampling inspection mechanism 6 includes a clamping device 61 for clamping the bar on the frontmost discharge station 33 into the runout detection mechanism 1 for runout detection.

[0053] Example 2

[0054] To improve detection efficiency and increase the feeding speed of the bars one by one, the pusher 221 moves upwards and pushes several bars at a high frequency and speed, which leads to frequent collisions between the bars and increases the probability of damage. Therefore, to solve this technical problem, reference is made to... Figure 10-12 The difference between this embodiment and Embodiment 1 or 2 is that:

[0055] The side wall of the adjusting plate 27 is provided with several material dividing plates 271 with the same inclination angle as the guide member 23 and spaced vertically. The several material dividing plates 271 divide the storage area 215 into several storage layers 2151 with vertical spacing for storing single rows of bars. The front ends of the lower material dividing plates 271 are respectively provided with flexible parts 272 that move vertically. The front ends of the flexible parts 272 are arc-shaped from bottom to top and gradually increase in width from top to bottom with the front inner wall of the hopper 21, corresponding to the pushing of the pusher member 221. In the material area 273, the distance between the front end of the uppermost flexible part 272 and the upper plurality of material distribution partitions 271 and the front wall of the hopper 21 is adapted to the outer diameter of a single bar. This structure, through the addition of several flexible layers arranged in an arc shape from bottom to top on the rear and upper sides of the pushing area 273, achieves flexible buffering of the upward movement of the bar within the pushing area 273 when the pushing member 221 moves upward, by means of the several flexible parts 272. Furthermore, the pushing area 273, whose width gradually increases from top to bottom... The configuration of 73 increases the distance between the bottom flexible section 272 and the pusher 221, preventing interference between them. It also ensures that only a small portion of the bars are stacked in the pusher area 273 during each push, while the majority of the bars are arranged in single rows within several storage layers 2151 and supported by several dividing partitions 271. This significantly reduces the number of bars stacked in the pusher area 273, lowers the pushing pressure of the pusher 221, reduces the number of bars pushed by the pusher 221, and further reduces the amount of bars pushed by the pusher 221. The flexible sections 272 also help to control the weight distribution of the smaller portion of the bars. The movement of the bars is flexibly restricted, so that when a small number of bars are pushed upward, they are confined within a limited pushing area 273. This avoids collision space between small numbers of bars, allowing the small number of bars to move upward stably as a whole after being pushed by the high-frequency and high-speed pushing force of the pushing component 221. This avoids the situation where frequent collisions between several bars increase the probability of damage. In other words, while ensuring the efficiency of feeding bars one by one, the pushing component 221 can work at a relatively high frequency and speed to ensure the safety and stability of the bars in the hopper 21 when pushed upward by the pushing component 221.

[0056] The arrangement of several storage layers 2151 greatly increases the difficulty of loading bar stock into the silo 21. Therefore, in order to improve the convenience of loading bar stock into the silo 21, the feeding mechanism 2 also includes a filling device 28. The left and right side walls of the silo 21 are respectively recessed with vertically extending grooves 216, and the rear wall is provided with a detachable, vertically sliding rear sealing plate 217 inserted between the two grooves 216. Several rear adjustment grooves 214 are provided on the inner wall of the rear sealing plate 217. The filling device 28 includes a hopper 281 with the lower front end for inserting several rear adjustment grooves 214 and the left and right front ends for sliding vertically inserted between the two grooves 216. The front wall of the hopper 281 is provided with a filling port 2811 corresponding to several storage layers 2151, and the inner bottom is inclined forward and downward to form a guide surface 2812 connecting the filling port 2811. The above structure enables the hopper 281 and rear sealing plate 217 to slide down to the bottom storage layer 2151 corresponding to the filling port 2811 for filling. After the bottom storage layer 2151 is full, the hopper 281 and rear sealing plate 217 are moved up to the storage layer 2151 corresponding to the upper layer of the filling port 2811 for filling. This process is repeated from bottom to top, filling the storage layer 2151 corresponding to the rear wall of the hopper 21 from the rear opening. Then, the hopper 281 is moved forward to fill the remaining storage layer 2151. The hopper 281 is then disassembled and the flow is restored. After the sealing plate 217 is fixed by the connecting pin and the slide 216, the filling work of the hopper 21 is completed. Under the premise of improving the stability of the rods when the pusher 221 pushes the material by adding several storage layers 2151 and several flexible parts 272, the convenience of filling the hopper 21 is improved. By filling the material layer by layer from bottom to top, the rods in the pusher area 273 are stacked layer by layer, avoiding the rods of the uppermost storage layer 2151 from falling from too high into the pusher area 273 and being damaged, thus improving the stability of the filling of the hopper 21.
