Description

Technical Field

[0001] This invention relates to the field of bar stock inspection and conveying technology, and in particular to a fully automatic bar stock inspection and packaging equipment. Background Technology

[0002] In the manufacturing process of precision cutting tools, bar stock, as the core raw material for tool machining, must first undergo precision grinding of its outer diameter using a centerless grinding machine. After grinding, the bar stock must undergo appearance defect inspection, dimensional verification, and standardized packaging before it can be transferred to the subsequent cutting edge forming process. With the continuous improvement of the efficiency of centerless grinding, the processing speed of the back-end inspection and packaging processes has become a key factor restricting the overall production line capacity.

[0003] Currently, the industry mostly adopts a layout scheme of separate independent equipment for the processing of bar stock after the centerless mill discharge: after the bar stock flows out of the centerless mill discharge conveyor line, it is transferred to the inspection station by manual or single-station transfer robot; after the inspection is completed, the bar stock is transferred to the boxing station by the same transfer mechanism, and falls into the box through the unloading structure to complete the storage.

[0004] In practical production applications, the above solutions have several shortcomings: A single-station transfer mechanism can only complete a single material handling or unloading action per cycle. The two processes of feeding the bar stock to the inspection station and unloading it to the boxing station after inspection need to be executed sequentially and step-by-step. This results in a long workpiece transfer cycle, low overall processing efficiency, and difficulty in matching the high-speed continuous output rhythm of the centerless mill. It also easily leads to bar stock accumulation at the output end, which in turn restricts the mill's processing capacity. Meanwhile, the conventional single-channel feeding structure has limited capacity to buffer bar stock at a time, making it impossible to achieve orderly buffering and alternating output of multiple bars. The single output volume is small, resulting in low boxing efficiency and poor boxing regularity. Furthermore, the feeding cycle and the front-end inspection process are difficult to reliably connect, leading to insufficient continuity in the automated operation of the entire line and making it difficult to achieve fully automated and unmanned processing of the bar stock after the centerless mill output. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems in the prior art and provide a fully automatic bar material inspection and cartoning equipment to overcome the shortcomings of low automation and low cartoning efficiency in existing inspection and cartoning lines.

[0006] The technical solution adopted by this invention to solve its technical problem is: a fully automatic bar material inspection and packaging device, comprising: The feeding conveyor line is used to continuously transport the bar stock to be tested; The appearance inspection mechanism includes a first transfer mechanism, a vision inspection module, and a first positioning seat. The first transfer mechanism is used to pick up the bar stock to be inspected one by one from the feeding conveyor line and place it on the first positioning seat. The vision inspection module is set facing the first positioning seat and is used to collect the appearance image of the bar stock on the first positioning seat for visual inspection. The boxing mechanism includes a boxing conveyor line and a dual-channel unloading mechanism installed at the end of the boxing conveyor line. The first transfer mechanism is also used to pick up the bar stock that has completed appearance inspection from the first positioning seat and place it on the boxing conveyor line. The dual-channel unloading mechanism is provided with two parallel storage channels. The two storage channels can alternately receive multiple bar stock conveyed by the boxing conveyor line and alternately unload them into the box.

[0007] As a further improvement of the present invention, the first transfer mechanism includes a dual-slide linear module, two first linear modules, and two clamping mechanisms. The dual-slide linear module is provided with two slides that move synchronously in the same direction. The two first linear modules are installed one-to-one on the two slides in the vertical direction. The two clamping mechanisms are respectively installed on the two first linear modules. Each clamping mechanism includes a gripper cylinder and two grippers installed on the gripper cylinder. When the dual-slide linear module and one of the first linear modules jointly drive the corresponding clamping mechanism to grab the bar stock from the feeding conveyor line and place it on the first positioning seat, the dual-slide linear module and the other first linear module synchronously drive the corresponding clamping mechanism to grab the bar stock that has completed appearance inspection from the first positioning seat and place it on the boxing conveyor line.

[0008] As a further improvement of the present invention, the first positioning seat is provided with a V-shaped groove for positioning the bar and a limiting baffle for limiting the axial ends of the bar; a first cylinder and a first rotating mechanism driven by the first cylinder to perform lifting and lowering motion are also installed on a first linear module near the feeding conveyor line. The first rotating mechanism includes a first motor and a first drive wheel installed at the output end of the first motor. The first motor is used to drive the first drive wheel to rotate the bar in the V-shaped groove.

[0009] As a further improvement of the present invention, the boxing mechanism further includes a second linear module and a lifting mechanism. The lifting mechanism is mounted on the second linear module, and the boxing conveyor line is mounted on the lifting mechanism. The boxing conveyor line includes a conveyor belt, and the conveyor belt has teeth evenly spaced around its outer surface. A trough that can only accommodate one bar is formed between two adjacent teeth.

[0010] As a further improvement of the present invention, the dual-channel feeding mechanism includes an arc-shaped baffle, a dual-channel feeding nozzle disposed at the bottom of the arc-shaped baffle, and a transverse movement mechanism, a blocking mechanism, and a blocking mechanism installed on the dual-channel feeding nozzle. Both storage channels are vertically arranged within the dual-channel feeding nozzle. The arc-shaped baffle is installed at the conveying end of the boxing conveyor line, forming a bar material guiding channel between them. The bar material guiding channel leads to the feed inlet at the upper end of the two storage channels. The transverse movement mechanism is disposed on the feed inlet side of one of the storage channels on the upstream side, and is used to block or open the feed inlet of that storage channel. The blocking mechanism is disposed on the outlet side of the bar material guiding channel, and is used to limit and block the bar material, cooperating with the transverse movement mechanism to alternately buffer the bar material into the two storage channels. The blocking mechanism is disposed at the bottom of the two storage channels, and is used to alternately block and open the discharge outlet at the lower end of the two storage channels.

[0011] As a further improvement of the present invention, the bottom of the dual-channel feeding nozzle is provided with a feeding port, and the discharge ports at the lower ends of the two storage channels converge and connect to the feeding port; the blocking mechanism is housed in the feeding port.

[0012] As a further improvement of the present invention, the fully automatic bar stock inspection and cartoning equipment also includes a box feeding mechanism. The box feeding mechanism includes a box storage bin, a box pushing mechanism, a lifting platform, and a box conveyor line. The box storage bin is used to stack multiple boxes. The box pushing mechanism is located at the bottom of the box storage bin and is used to push the bottom box in the box storage bin to the lifting platform. The lifting platform is used to carry the box and can lower the box onto the box conveyor line.

[0013] As a further improvement of the present invention, the fully automatic bar stock inspection and boxing equipment also includes a geometric parameter inspection mechanism, which includes a second transfer mechanism, a second positioning seat and a geometric parameter detector. The second transfer mechanism is used to pick up bars one by one from the boxing conveyor line and place them on the second positioning seat; the geometric parameter detector is used to collect the geometric parameters of the bars on the second positioning seat.

[0014] As a further improvement of the present invention, a point contact support assembly is installed on the second positioning seat. The point contact support assembly includes a steel ball and at least two wear-resistant rods. A positioning hole is opened on the second positioning seat in the horizontal direction, and the steel ball is positioned directly opposite the positioning hole. The two wear-resistant rods are distributed in a V-shape, and the central axes of the two wear-resistant rods are perpendicular to the extension direction of the positioning hole. At the same time, both wear-resistant rods have at least a portion protruding into the positioning hole.

[0015] As a further improvement of the present invention, the geometric parameter detection mechanism further includes a second cylinder and a second rotating mechanism driven by the second cylinder to perform lifting and lowering movements. The second rotating mechanism includes a second motor and a second drive wheel installed at the output end of the second motor. The second motor is used to drive the second drive wheel to rotate the bar on the second positioning seat.

[0016] The beneficial effects of this invention are: 1. This invention provides a fully automatic bar stock inspection and packaging equipment, which integrates a feeding conveyor line, an appearance inspection mechanism and a packaging mechanism into a single machine. It realizes fully automated and continuous operation of bar stock feeding, appearance visual inspection and orderly dual-channel feeding and packaging. Moreover, the dual-channel feeding buffer capacity is larger and the feeding cycle is significantly shortened, effectively improving the overall production efficiency of the bar stock processing line.

[0017] 2. This invention uses a transverse movement mechanism and a blocking mechanism to coordinate and control the flow of bar stock, enabling the bar stock to alternately enter two storage channels for buffering. The bottom blocking mechanism can alternately block and open the discharge ports at the bottom of the two storage channels, controlling the orderly feeding of the two sets of channels. The parallel buffering and alternating discharge of the dual channels can accommodate multiple bar stock at the same time, and the feeding efficiency is greatly improved compared with the single channel structure. The orderly flow and timed discharge can avoid collisions and tilting of multiple bar stock falling at the same time, ensuring that the bar stock in the material box is neatly arranged.

[0018] 3. This invention uses a geometric parameter detector to collect real-time data on the diameter, roundness, and runout of the bar stock during rotation, simultaneously verifying the dimensional accuracy and geometric tolerances after centerless grinding. It integrates visual inspection of appearance defects with geometric accuracy sampling into a single integrated device, further improving the automation level of the equipment. At the same time, the point contact support component forms local point contact support for the bar stock, ensuring accurate and unbiased detection data of geometric parameters such as the diameter, roundness, and rotational runout of the bar stock.

[0025] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0026] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0027] See Figures 1 to 9 The present invention provides a fully automatic bar material inspection and packaging equipment, including a workbench 6 and a feeding conveyor line 1, an appearance inspection mechanism 2 and a packaging mechanism 3, all installed on the workbench 6.

[0028] The feeding conveyor line 1 is connected to the centerless mill equipment at its starting end. The bar stock 100 processed by the centerless mill equipment will flow into the feeding conveyor line 1. The feeding conveyor line 1 is used to continuously convey the bar stock 100 to be tested to the feeding station at its end.

[0029] The appearance inspection mechanism 2 includes a first transfer mechanism 21, a vision inspection module 22, and a first positioning seat 23. The first transfer mechanism 21 is used to pick up the bar stock 100 to be inspected one by one from the loading station on the loading conveyor line 1 and place it on the first positioning seat 23. The vision inspection module 22 is set facing the first positioning seat 23 and is used to collect appearance images of the bar stock 100 on the first positioning seat 23 for visual inspection.

[0030] The cartoning mechanism 3 includes a cartoning conveyor line 31 and a dual-channel unloading mechanism 32 installed at the end of the cartoning conveyor line 31. The first transfer mechanism 21 is also used to pick up the bar stock 100 that has completed appearance inspection from the first positioning seat 23 and place it on the cartoning conveyor line 31. The dual-channel unloading mechanism 32 is provided with two parallel storage channels 320. The two storage channels 320 can alternately receive multiple bar stock 100 conveyed by the cartoning conveyor line 31 and alternately unload them into the material box 200.

[0031] This invention integrates the feeding conveyor line 1, the appearance inspection mechanism 2, and the boxing mechanism 3 into a single unit, specifically designed for the continuous automated processing of the raw material bar stock 100 after centerless grinding. This eliminates the need for manual transfer between multiple independent machines, resulting in a highly integrated and smaller-footprint device. The feeding conveyor line 1 provides a continuous and stable supply of the ground bar stock 100, ensuring uninterrupted processing. The appearance inspection mechanism 2, equipped with an independent first transfer mechanism 21, automatically completes the two processes of bar stock loading and unloading after inspection. The vision inspection module 22, facing the first positioning seat 23, captures a complete appearance image of the bar stock 100 for inspection. Various appearance defects such as end face chipping, notches, and peripheral scratches are eliminated. The boxing mechanism 3 is equipped with a dual-channel unloading mechanism 32. The dual-channel unloading mechanism 32 has two parallel storage channels 320. The two storage channels 320 can alternately receive multiple bars 100 conveyed by the boxing conveyor line 31 and alternately unload them into the box 200. Compared with the traditional single-channel unloading structure, the buffer capacity is larger and the unloading cycle is significantly shortened. It can match the high-speed feeding cycle of the front end, greatly reducing the labor production cost. The whole machine realizes the fully automated and continuous operation of bar feeding, appearance visual inspection, and dual-channel orderly unloading and boxing, effectively improving the production efficiency of the entire line after tool and bar processing.

[0032] To facilitate understanding of this solution, Figure 1 A three-dimensional coordinate system is established with the front edge of the worktable 6 in the X-axis direction, the right edge in the Y-axis direction, and the height of the worktable 6 in the Z-axis direction.

[0033] Among them, the feeding conveyor line 1 is arranged along the X-axis, which can be, but is not limited to, a belt conveyor line, and the axial direction of the bar stock 100 conveyed by the feeding conveyor line 1 is also distributed along the X-axis direction.

[0034] See Figure 2The first transfer mechanism 21 includes a double-slide linear module 211, two first linear modules 212, and two clamping mechanisms. The double-slide linear module 211 is arranged along the X-axis and can be, but is not limited to, a ball screw type double-slide synchronous linear module with two slides that move synchronously in the same direction. The two first linear modules 212 are mounted one-to-one on the two slides along the vertical direction, or the Z-axis. The double-slide linear module 211 drives the two slides to move the two first linear modules 212 synchronously in the same direction.

[0035] The first linear module 212 can be a ball screw linear module or a linear motor, etc.

[0036] Furthermore, both clamping mechanisms are respectively mounted on the two first linear modules 212 along the Z-axis. Both clamping mechanisms include a gripper cylinder 213 and two grippers 214 mounted on the gripper cylinder 213. The gripper cylinder 213 is used to drive the two grippers 214 to clamp or release the bar stock 100.

[0037] The dual-slide linear module 211 and a first linear module 212 on the right jointly drive the corresponding clamping mechanism to grab the bar stock 100 from the feeding conveyor line 1 and place it on the first positioning seat 23. At the same time, the dual-slide linear module 211 and another first linear module 212 on the left jointly drive the corresponding clamping mechanism to grab the bar stock 100 that has completed appearance inspection from the first positioning seat 23 and place it on the boxing conveyor line 31. The first transfer mechanism 21 in this invention uses a dual-slide linear module 211 with two sets of independent clamping components to realize the parallel and synchronous operation of two transfer processes, abandoning the step-by-step serial operation mode of traditional transfer mechanisms, greatly shortening the cycle time of a single transfer cycle, and avoiding material accumulation at the outlet of the feeding conveyor line 1.

[0038] Furthermore, the first positioning seat 23 is provided with a V-shaped groove for positioning the bar stock 100 and two limiting baffles 231 distributed on both sides of the V-shaped groove along the X-axis direction. The two limiting baffles 231 are used to limit the axial ends of the bar stock 100 in the V-shaped groove, restrict the axial movement of the bar stock 100, ensure that the position of the bar stock is fixed when the visual image is acquired, and avoid the bar stock 100 from shifting and causing the appearance defects to be missed. A first cylinder 215 and a first rotating mechanism driven by the first cylinder 215 to perform lifting and lowering motion are also installed along the Z-axis of a first linear module 212 near the feeding conveyor line 1 (i.e., a first linear module 212 on the right side). The first rotating mechanism includes a first motor 216 and a first drive wheel 217 installed at the output end of the first motor 216. The first motor 216 is used to drive the first drive wheel 217 to rotate the bar 100 in the V-groove, so that the vision inspection module 22 can collect images of the entire outer periphery and the entire contour area of ​​the bar 100, completely eliminating the blind spot of vision inspection and accurately identifying minor scratches, end face defects and other appearance defects.

[0039] Preferably, the visual inspection module 22 uses a CCD camera.

[0040] See Figure 3 The boxing mechanism 3 also includes a second linear module 33 and a lifting mechanism 34. The second linear module 33 is arranged along the Y-axis and can be a ball screw linear module or a linear motor. The lifting mechanism 34 is mounted on the second linear module 33, and the boxing conveyor line 31 is mounted on the lifting mechanism 34. The second linear module 33 is used to drive the lifting mechanism 34 and the boxing conveyor line 31 to move along the Y-axis. The lifting mechanism 34 is used to drive the boxing conveyor line 31 to perform lifting and lowering movements, thereby synchronously adjusting the discharge position and discharge height of the boxing conveyor line 31, and thus neatly arranging the bar stock 100 from front to back (or from back to front) and from low to high into the material box 200.

[0041] The lifting mechanism 34 uses existing conventional inclined lifting platforms or linear modules.

[0042] See Figure 4 The boxing conveyor line 31 includes a conveyor belt 311 and a conveyor belt drive device for driving the conveyor belt 311 to rotate. The conveyor belt 311 has teeth 3111 evenly spaced around its outer surface. A trough 3112 that can only accommodate one bar 100 is formed between two adjacent teeth 3111, so that the bar 100 is separated and isolated from each other during the conveying process. The orderly separated single trough 3112 also facilitates the diversion of bar materials by the rear dual-channel unloading mechanism 32, ensuring that the alternating buffer unloading logic is stable and reliable.

[0043] Furthermore, the dual-channel feeding mechanism 32 includes an arc-shaped baffle 321, a dual-channel feeding nozzle 322, a transverse movement mechanism 323, a blocking mechanism 324, and a blocking mechanism 325. The arc-shaped baffle 321 is installed at the conveying end of the boxing conveyor line 31, forming a bar material guiding channel between the arc-shaped baffle 321 and the conveying end of the boxing conveyor line 31. The dual-channel feeding nozzle 322 is fixedly installed at the bottom of the arc-shaped baffle 321 and is connected to the bar material guiding channel; two storage channels 320 are both vertically arranged inside the dual-channel feeding nozzle 322, and the bar material guiding channel leads to the feed inlet at the upper end of the two storage channels 320.

[0044] The transverse movement mechanism 323, the blocking mechanism 324, and the material blocking mechanism 325 are all installed on the dual-channel discharge nozzle 322. The transverse movement mechanism 323 is located in a material storage channel 320 on the upstream side. Figure 4On the left side of the material storage channel 320 shown, the material storage channel 320 is used to block or open the material storage channel 320; the blocking mechanism 324 is located on the outlet side of the bar stock guide channel, which is used to limit and block the bar stock 100, and cooperates with the transverse movement mechanism 323 to make the bar stock 100 alternately buffered into the two material storage channels 320; the blocking mechanism 325 is located at the bottom of the two material storage channels 320, which is used to alternately block and open the outlet of the lower end of the two material storage channels 320.

[0045] Specifically, the transverse mechanism 323 includes a transverse slider and a transverse drive device connected to the transverse slider. The transverse slider is slidably mounted on the top of the dual-channel feed nozzle 322 and is located to the left of the feed inlet of the left storage channel 320. The transverse drive device is used to drive the transverse slider to slide left and right to block or open the feed inlet of the left storage channel 320.

[0046] The blocking mechanism 324 includes a blocking slider and a blocking drive device connected to the blocking slider. The blocking slider is slidably mounted on the top of the dual-channel feed nozzle 322 and is located above the partition between the two storage channels 320. The blocking drive device is used to drive the blocking slider to slide left and right to limit and block the bar stock 100.

[0047] When the lateral sliding slider is positioned to the left of the feed inlet of the left storage channel 320, its feed inlet is opened. Simultaneously, the blocking slider is positioned above the partition between the two storage channels 320. At this time, the blocking slider prevents the bar stock 100 from entering the right storage channel 320, and the bar stock 100 can only fall into the left storage channel 320 along the bar stock guide channel. When the bar stock 100 in the left storage channel 320 reaches a set quantity, the lateral driving device drives the lateral sliding slider to slide to the right, blocking the feed inlet of the left storage channel 320. At the same time, the blocking driving device drives the blocking slider to slide to the right of the feed inlet of the right storage channel 320. At this time, the lateral sliding slider prevents the bar stock 100 from entering the left storage channel 320, and the bar stock 100 can only fall into the right storage channel 320 along the bar stock guide channel, until the bar stock 100 in the right storage channel 320 reaches a set quantity. This cycle repeats continuously.

[0048] The material blocking mechanism 325 includes a material blocking transfer block and a material blocking drive device connected to the material blocking transfer block. The bottom of the dual-channel discharge nozzle 322 is provided with a discharge port 3221, which includes a vertical section and a funnel-shaped material switching section connected to the top of the vertical section. The discharge ports at the lower ends of the two material storage channels 320 converge through the material switching section of the discharge port 3221 and lead to the vertical section. The material blocking transfer block is slidably installed in the material switching section of the discharge port 3221.

[0049] When the blocking drive device drives the blocking transfer block to slide to the left, a vertical channel connecting the right storage channel 320 and the discharge port 3221 is formed on the right side of the blocking transfer block. The bar stock in the right storage channel 320 falls freely along the channel under its own gravity. When the blocking drive device drives the blocking transfer block to slide to the right, a vertical channel connecting the left storage channel 320 and the discharge port 3221 is formed on the left side of the blocking transfer block. The bar stock in the left storage channel 320 falls freely along the channel under its own gravity.

[0050] This invention uses the cooperation of the transverse mechanism 323 and the blocking mechanism 324 to control the flow of bar stock, so that the bar stock alternately enters the two storage channels 320 for buffering. The blocking mechanism 325 set at the bottom can alternately block and open the lower outlet of the two storage channels 320, and control the two sets of channels to feed material in an orderly manner. The parallel buffering and alternating discharge of the dual channels can accommodate multiple bar stock 100 at the same time, and the feeding efficiency is greatly improved compared with the single channel structure. The orderly flow and timed discharge can avoid collision and tilting of multiple bar stock falling at the same time, and ensure that the bar stock in the material box 200 is arranged neatly.

[0051] Alternatively, the transverse drive device, the blocking drive device, and the material blocking drive device can all be pneumatic cylinders, electric cylinders, etc.

[0052] In this embodiment, each storage channel 320 can accommodate eight bar stock 100.

[0053] In addition, the fully automatic bar material detection and packaging equipment of the present invention also includes a material box feeding mechanism 4, which is used to realize the automatic supply and external conveying of the material box 200.

[0054] like Figure 1 and Figure 5 As shown, the material box feeding mechanism 4 includes a material box storage bin 41, a material box pushing mechanism 42, a lifting platform 43, and a material box conveyor line 44. The material box storage bin 41 is used to stack multiple empty material boxes 200. The material box pushing mechanism 42 is located at the bottom of the material box storage bin 41 and is used to push the bottom material box 200 in the material box storage bin 41 onto the lifting platform 43. The lifting platform 43 is used to carry the material box 200 and can lower the material box 200 filled with bar stock 100 onto the material box conveyor line 44, from which it is conveyed outwards. The entire material box feeding process is fully automated and can be synchronized with the front-end bar stock detection and unloading processes, greatly reducing manual box replenishment operations, enabling the equipment to operate continuously without human intervention for extended periods, and reducing labor production costs.

[0055] In this embodiment, the material box pushing mechanism 42 includes a push plate and a linear module connected to the push plate; the lifting platform 43 includes a lifting tray and a hydraulic cylinder connected to the lifting tray; and the material box conveying line 44 is a belt conveyor.

[0056] It is worth mentioning that the fully automatic bar stock inspection and packaging equipment of the present invention also includes a geometric parameter inspection mechanism 5, which is used to sample and inspect the bar stock 100 to perform geometric parameter inspection.

[0057] like Figures 6 to 9 As shown, the geometric parameter detection mechanism 5 includes a second transfer mechanism 51, a second positioning seat 52, and a geometric parameter detector 53. The second transfer mechanism 51 can be, but is not limited to, a gantry robot, on which a clamping mechanism (same as the structure described above) is mounted. The second transfer mechanism 51 is used to pick up bar stock 100 one by one from the boxing conveyor line 31 and place them on the second positioning seat 52. The geometric parameter detector 53 is used to collect the geometric parameters of the bar stock 100 on the second positioning seat 52.

[0058] Preferably, the geometric parameter detector 53 is a laser detector.

[0059] Furthermore, a point-contact support assembly is installed on the second positioning seat 52. The point-contact support assembly includes a steel ball 54 and wear-resistant rods 55 made of hard alloy material. In this embodiment, the number of wear-resistant rods 55 is specifically, but not limited to, four. A positioning hole 521 is opened on the second positioning seat 52 along the horizontal direction. The steel ball 54 is installed on the second positioning seat 52 and is positioned directly opposite the positioning hole 521. The four wear-resistant rods 55 are distributed in pairs in a V-shape, and the central axis of each wear-resistant rod 55 is perpendicular to the extension direction of the positioning hole 521. At the same time, each wear-resistant rod 55 has at least a partial protrusion into the positioning hole 521, so that the rod 100 only forms local point-contact support with the steel ball 54 and the wear-resistant rods 55, ensuring that the detection data of geometric parameters such as the diameter, roundness, and rotational runout of the rod are accurate and without deviation. At the same time, the point-contact support has a small contact area, and the support assembly is less subjected to wear caused by long-term friction with the workpiece, extending the service life of the steel ball 54 and the wear-resistant rods 55, and reducing the frequency of parts replacement and equipment maintenance costs.

[0060] See Figure 7 The geometric parameter detection mechanism 5 also includes a second cylinder 56 and a second rotating mechanism driven by the second cylinder 56 to perform lifting and lowering movements. The second rotating mechanism includes a second motor 57 and a second drive wheel 58 installed at the output end of the second motor 57. The second motor 57 is used to drive the second drive wheel 58 to rotate the bar 100 on the second positioning seat 52, so that the geometric parameter detector 53 can completely collect the outer diameter data of the bar and completely capture the radial runout value when the workpiece rotates, ensuring that the form and position parameters are detected comprehensively and without omission.

[0061] The working principle of the fully automatic bar stock inspection and packaging equipment of this invention is as follows: Before the equipment is started, several empty material boxes 200 are stacked in the material box storage bin 41. The material box pushing mechanism 42 pushes the bottom empty material box 200 to the lifting platform 43, so that the material box 200 is aligned with the discharge port 3221 of the dual-channel unloading mechanism 32, and the standby preparation is completed.

[0062] The tool bar 100 processed by the centerless grinding equipment flows out continuously and enters the beginning of the feeding conveyor line 1. The feeding conveyor line 1 uniformly conveys the bar 100 to the end feeding station along the X-axis direction, waiting for transfer feeding.

[0063] The first transfer mechanism 21 is activated, and the double slide linear module 211 drives the two slides to move the two sets of clamping mechanisms synchronously in the same direction. The clamping mechanism on the side closer to the feeding conveyor line 1 descends under the drive of the first linear module 212. The gripper cylinder 213 drives the gripper 214 to grab the bar stock 100 to be inspected at the feeding station. After rising and resetting, it moves with the slide to the top of the first positioning seat 23. It descends again to place the bar stock 100 in the V-shaped groove of the first positioning seat 23. The two ends of the bar stock 100 are limited by the limiting baffle 231 to prevent axial movement. At the same time, the clamping mechanism on the other side synchronously grabs the bar stock 100 that has completed the appearance inspection on the first positioning seat 23 and moves it synchronously with the slide to the top of the boxing conveyor line 31. The bar stock 100 is placed stably in the material trough 3112 of the conveyor belt 311. The two sets of picking and unloading actions are completed synchronously, realizing parallel operation of feeding and unloading, which greatly shortens the transfer cycle.

[0064] After the bar stock 100 is placed in the first positioning seat 23, the first cylinder 215 drives the first rotating mechanism to descend, so that the first drive wheel 217 abuts against the outer surface of the bar stock 100. The first motor 216 starts and drives the first drive wheel 217 to rotate, thereby driving the bar stock 100 to rotate circumferentially at a uniform speed in the V-groove. The vision inspection module 22 simultaneously acquires the appearance images of the outer periphery of both ends of the bar stock 100 to identify whether there are scratches on the surface of the bar stock 100, whether there are chips or notches on the end face, or other appearance defects. After the appearance inspection is completed, the first rotating mechanism rises and resets, waiting for the next transfer cycle.

[0065] After completing the appearance inspection, the bar stock 100 moves forward along the conveyor belt 311 of the boxing conveyor line 31 in the conveying direction. The equally spaced protrusions 3111 on the surface of the conveyor belt 311 form independent material troughs 3112, in which a single bar stock 100 is accommodated, separated from each other and conveyed in an orderly manner. The equipment triggers the geometric parameter detection process according to the preset program. The second transfer mechanism 51 grabs the bar stock 100 to be inspected from the boxing conveyor line 31 and transfers it into the positioning hole 521 of the second positioning seat 52, where it is supported by point contact between the wear-resistant bars 55 distributed in a V-shape and the steel balls 54.

[0066] During the sampling inspection, the second cylinder 56 drives the second rotating mechanism to descend, causing the second drive wheel 58 to abut against the outer circle of the bar stock 100. The second motor 57 drives the bar stock 100 to rotate at a constant speed. The geometric parameter detector 53 simultaneously collects the outer diameter, roundness, and radial runout data of the bar stock 100 during rotation to complete the geometric accuracy verification. The qualified bar stock 100 is sent back to the boxing conveyor line 31 by the second transfer mechanism 51 to continue forward transport, while the unqualified workpieces are transferred to the unqualified product storage area to realize automatic sorting of defective products.

[0067] The bar stock 100 is conveyed to the end of the boxing conveyor line 31 and guided by the bar stock guide channel formed by the arc baffle 321 and the end of the conveyor, entering the feeding area of ​​the dual-channel discharge nozzle 322. The lateral movement mechanism 323 and the blocking mechanism 324 work together to control the bar stock 100 to alternately enter the two storage channels 320 for buffering: In the initial state, the lateral movement mechanism 323 opens the feed port of the left storage channel 320, and the blocking mechanism 324 limits and blocks the feed port of the right storage channel 320. The bar stock 100 falls into the left storage channel 320 along the guide channel and is stacked and buffered in sequence. When the bar stock 100 in the left storage channel 320 is buffered to a set quantity, the lateral movement mechanism 323 moves laterally to block the feed port of the left storage channel 320. At the same time, the blocking mechanism 324 moves laterally to switch the limit position and opens the feed port of the right storage channel 320. The subsequent bar stock 100 is transferred to the right storage channel 320 for buffering. This cycle is used to realize the alternating storage of the two channels.

[0068] When the corresponding workstation in the lower material box 200 is waiting for material, the blocking mechanism 325 is activated, alternately opening the lower outlet of the two storage channels 320. The buffered bar stock 100 falls orderly into the material box 200 through the discharge port 3221 under its own gravity. During the feeding process, the second linear module 33 drives the boxing conveyor line 31 and the dual-channel feeding mechanism 32 to move step by step along the Y-axis. The lifting mechanism 34 adjusts the feeding height in sync, so that the bar stock 100 is placed smoothly and neatly in the material box 200 row by row and layer by layer, avoiding the bar stock from being tilted or stacked.

[0069] After a single material box 200 is filled with bar stock 100, the lifting platform 43 lowers the full material box to the conveying surface of the material box conveyor line 44, and the full material box is conveyed outward by the material box conveyor line 44 to the next process; at the same time, the material box pushing mechanism 42 is activated again to push the next empty material box 200 in the material box storage bin 41 to the lifting platform 43, and enter the next round of boxing cycle.

[0070] The entire machine operates with continuous and sequential processes, enabling fully automated, unmanned operation of bar stock feeding, full-circumference appearance inspection, geometric parameter sampling, dual-channel alternating buffer feeding, and automatic supply and output of the material box. This effectively matches the high-speed output cycle of the centerless mill, improving production efficiency and product quality stability.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
