Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roller detection, in particular to a roller automatic detection device. BACKGROUND

[0002] The roller is an element that bears load when the bearing is running, and is the weakest part in the roller bearing. The manufacturing quality of the roller has a great influence on the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.), and the quality of the roller is a main factor affecting the service life of the bearing. Therefore, the quality of the roller needs to be detected after the roller is processed.

[0003] The cylindrical roller is a common kind of roller. After the cylindrical roller is processed by a processing device, it needs to go through a series of detection steps such as outer diameter and height. Currently, the outer diameter detection device for detecting the outer diameter of the cylindrical roller bearing and the device for detecting the height of the cylindrical roller bearing are performed separately.

[0004] In the related art, after the outer diameter of the cylindrical roller is detected by the outer diameter detection device, the unqualified products are removed by workers, the qualified products are placed into a collection box and transported to the height detection device for height detection, and finally the workers classify the cylindrical rollers with different heights after the detection is completed, thereby causing low efficiency of quality detection. SUMMARY

[0005] In order to improve the detection efficiency of the roller, the present application provides a roller automatic detection device.

[0006] The roller automatic detection device provided by the present application adopts the following technical scheme:

[0007] A roller automatic detection device, comprising:

[0008] A feeding mechanism connected to and communicated with a device for processing rollers;

[0009] A hardness detection mechanism for detecting the hardness of the roller;

[0010] An outer diameter detection mechanism, comprising a positioning assembly for positioning the roller, a ejector rod assembly cooperating with the positioning assembly to clamp the roller, and an outer diameter measuring assembly for measuring the outer diameter of the roller;

[0011] A height detection mechanism, comprising a material rotating disc assembly for placing the roller after the outer diameter is measured, a height measuring assembly for detecting the height of the roller on the material rotating disc assembly, and a rotating disc driving assembly for driving the material rotating disc assembly to rotate;

[0012] The transferring mechanism comprises a swing arm assembly and an adsorption assembly mounted on the swing arm assembly, and the adsorption assembly is used to transfer the roller on the feeding mechanism to the hardness detection mechanism, transfer the roller on the hardness detection mechanism to the outer diameter detection mechanism, and transfer the roller on the outer diameter detection mechanism to the height detection mechanism.

[0013] The discharging mechanism is used to transfer the roller on the height detection mechanism to the next process.

[0014] By adopting the above technical scheme, the processed roller enters the feeding mechanism, then the swing arm assembly drives the adsorption assembly to adsorb the roller on the feeding mechanism, and places the roller on the hardness detection mechanism through the swing displacement of the swing arm assembly to detect the hardness of the roller, and then the roller with the detected hardness is transferred to the outer diameter detection mechanism through the cooperation of the swing arm assembly and the adsorption assembly.

[0015] When the roller is transferred to the outer diameter detection mechanism, the positioning assembly positions the roller, then the ejector rod assembly moves and cooperates with the positioning assembly to clamp and position the roller, and at this time, the outer diameter measurement assembly measures the outer diameter of the roller.

[0016] The roller with the measured outer diameter continues to be transferred to the rotating disc assembly through the transferring mechanism, the rotating disc assembly rotates under the drive of the rotating disc drive assembly, moves the roller to the lower side of the height measurement assembly for height detection, then the rotating disc assembly continues to rotate to move the measured roller to the position of the discharging mechanism, and the roller is transferred to the next process through the discharging mechanism.

[0017] In the process of moving the roller on the feeding mechanism to the hardness detection mechanism, the transferring mechanism also simultaneously moves the roller on the hardness detection mechanism to the outer diameter detection mechanism, and moves the roller on the outer diameter detection mechanism to the height detection mechanism. Through the above structure, the various mechanisms for detecting the roller are integrated on one device, and the transferring mechanism can simultaneously move the rollers on three different mechanisms on one side, thereby improving the detection efficiency of the roller.

[0018] Optionally, the feeding mechanism comprises a feeding track, a feeding rotating wheel and a feeding motor, a plurality of roller grooves are arranged on the circumferential wall of the feeding rotating wheel at intervals, the feeding track is in communication with the roller grooves, and the roller falls from the feeding track to the roller grooves, and the feeding motor drives the feeding rotating wheel to rotate.

[0019] By adopting the technical scheme, the processed roller rolls from the feeding track to a roller groove on the side of the feeding rotary wheel and communicates with the feeding track, then the feeding motor drives the feeding rotary wheel to rotate to rotate the roller in the roller groove on the side of the feeding rotary wheel to the upper side, that is, to vertically place the roller (that is, the central axis direction of the roller is vertical), thereby facilitating the transfer mechanism to move the roller to the next detection mechanism position.

[0020] With each rotation of the feeding rotary wheel, the roller in the feeding track will roll into the roller groove communicating therewith, and each rotation has the roller in a vertical state, thereby improving the detection efficiency.

[0021] Optionally, the positioning assembly comprises a first positioning rod and a second positioning rod, the ejector rod assembly comprises an ejector rod and an ejector rod driver for driving the ejector rod to move radially relative to the measured roller, and the first positioning rod, the second positioning rod and the ejector rod are arranged circumferentially around the measured roller.

[0022] By adopting the technical scheme, two-point positioning is formed under the action of the first positioning rod and the second positioning rod, and the transfer mechanism can relatively accurately move the roller to the corresponding position. Then the ejector rod driver drives the ejector rod to move and push the roller to move slightly until the first positioning rod, the second positioning rod and the ejector rod clamp and position the roller, at which time the outer diameter measurement can accurately measure the outer diameter of the roller.

[0023] Optionally, the material transfer disc assembly comprises a material transfer disc base and a rotating disc mounted on the material transfer disc base, a plurality of height detection grooves are formed on the side of the rotating disc away from the material transfer disc base, the height detection grooves are arranged circumferentially on the rotating disc, and the height measurement assembly is mounted on the material transfer disc base to detect the roller in the height detection groove.

[0024] By adopting the technical scheme, the arrangement of the material transfer disc base can make the roller in the height detection groove and the roller at the outer diameter detection mechanism position at about the same height, thereby facilitating the transfer mechanism to move the roller whose outer diameter has been measured to the height detection groove. With rotation of the rotating disc, the height measurement assembly detects the roller moved thereunder.

[0025] Optionally, the adsorption assembly comprises a suction pipe, a rubber suction cup and a buffer spring, a plug-in groove is formed on one side of the rubber suction cup, a vent hole is formed in the groove bottom of the plug-in groove, one end of the suction pipe is inserted into the plug-in groove, the other end of the suction pipe is connected with a suction pump, one end of the buffer spring abuts against the groove bottom of the plug-in groove, and the other end of the buffer spring abuts against the suction pipe.

[0026] By adopting the technical scheme, after the rubber suction disc abuts against the upper end face of the roller, the air pump performs air extraction through the air extraction pipe, the airflow between the rubber suction disc and the roller enters the plug-in groove through the air vent hole, and then is extracted to form negative pressure, thereby sucking up the roller.

[0027] In addition, the rubber suction disc reduces the risk of scratching the end face of the roller compared with a plastic product. When the rubber suction disc abuts against the end face of the roller, the buffer spring also has a buffering effect, further reducing the risk of scratching the end face of the roller. At the same time, the arrangement of the buffer spring also enables the rubber suction disc to adsorb rollers of different heights.

[0028] Optionally, the discharging mechanism comprises a rotating assembly for rotating the roller, a lifting driving assembly for driving the rotating assembly to ascend or descend to adsorb the roller, and a size defect collecting assembly for collecting size defect rollers.

[0029] By adopting the technical scheme, the lifting driving assembly drives the rotating assembly to descend and adsorb the roller whose outer diameter has been detected, and then the lifting driving assembly drives the rotating assembly to ascend to take the roller out of the height detection groove. If the roller is qualified, the rotating assembly rotates to place the roller in the next process. If the outer diameter or height of the roller is unqualified, the rotating assembly rotates to place the roller in the size defect collecting assembly, so that the rotating assembly does not idle and generate energy consumption every time.

[0030] Optionally, the rotating disc driving assembly comprises a rotating shaft, a connecting rod rotating disc, a first connecting rod, a second connecting rod, a ratchet disc and a ratchet gear.

[0031] The rotating disc, the connecting rod rotating disc and the ratchet disc are sleeved on the rotating shaft, and the rotating disc and the ratchet disc rotate synchronously.

[0032] The first connecting rod is rotatably installed on the swing arm assembly, one side of the second connecting rod is rotatably connected with the connecting rod rotating disc, the other side is rotatably connected with the first connecting rod, and the ratchet gear is rotatably installed on the connecting rod rotating disc and matched with the ratchet disc.

[0033] By adopting the technical scheme, the swing arm assembly moves the roller every time, so that the connecting rod rotating disc rotates a certain angle with the rotating shaft as the rotation axis along with the swing arm motion of the swing arm assembly when the swing arm assembly swings, and the first connecting rod and the second connecting rod are rotatably connected to reduce the occurrence of the connecting rod rotating disc being stuck when the swing arm assembly swings.

[0034] The ratchet installed on the connecting rod turntable rotates with the connecting rod turntable, and each rotation of the ratchet drives the ratchet wheel to rotate by a certain angle, and further drives the rotating disc to rotate, so as to transfer the roller to the lower side of the height measurement assembly for measurement. The above structure is mechanically linked, which is less susceptible to interference compared to electrical signal rotation, and runs more stably; at the same time, the motor driving the rotating disc to rotate is saved, and energy consumption is reduced.

[0035] Optionally, the lifting driving assembly comprises a reset spring, a first bevel gear, a second bevel gear, a transmission shaft, a transmission wheel and a linkage plate.

[0036] The first bevel gear is installed on the rotating shaft and rotates synchronously with the rotating shaft, the rotating shaft is rotatably installed on the material rotating disc base, the second bevel gear and the transmission wheel are both installed on the transmission shaft and rotate synchronously with the transmission shaft, and the second bevel gear is engaged with the first bevel gear.

[0037] The outer peripheral wall of the transmission wheel is provided with a plurality of convex teeth at intervals, the linkage plate is installed on the rotating assembly, and the linkage plate is provided with a rack engaged with the convex teeth.

[0038] The reset spring is used to drive the rotating assembly to reset after movement.

[0039] By adopting the above technical scheme, when the rotating disc rotates through the cooperation of the ratchet wheel and the ratchet, the rotating shaft will rotate synchronously with the rotating disc, and the transmission shaft will rotate under the cooperation of the first bevel gear and the second bevel gear. After the transmission shaft rotates, the transmission wheel is driven to rotate, the convex teeth on the transmission wheel will engage with the rack on the linkage plate to drive the rotating assembly to descend, after the linkage plate descends, the transmission wheel rotates to the smooth part between the adjacent two convex teeth, and the linkage plate will reset under the action of the reset spring, and the rotating assembly drives the roller to rise.

[0040] The above structure still uses the driving force when the swing arm assembly swings, and a pure mechanical linkage is generated between the rotating disc, compared with the cylinder driving the rotating assembly to ascend and descend, the driving source of the cylinder is saved, and the energy consumption is reduced.

[0041] Optionally, the material rotating disc base is provided with a hardness defective product guide pipe, and the material rotating disc base is provided with a discharging hole for communicating the defective product guide pipe with the height detection groove.

[0042] By adopting the above technical scheme, since the rotating disc rotates in the same direction under the cooperation of the ratchet and the ratchet teeth, the product with unqualified hardness continues to rotate after being detected by the height measuring assembly and passes through the blanking mechanism, and the blanking mechanism does not blank and lose energy consumption. After the defective product passes through the blanking mechanism, it will rotate to the blanking hole, at which time the roller will slide from the rotating disc to the guide pipe for collection. Since the rotating disc itself rotates, compared with separately setting a mechanism for recycling hardness defective products between the hardness detection mechanism and the outer diameter detection mechanism, the above structure saves space.

[0043] Optionally, the roller automatic detection device further comprises a distributing mechanism, the distributing mechanism comprising: a distributing conveying belt assembly having a plurality of roller channels;

[0044] a distributing box assembly arranged with a plurality of groups of boxes for containing rollers of different specifications;

[0045] a distributing manipulator assembly for moving the rollers in the different roller channels to the corresponding distributing box assemblies.

[0046] By adopting the above technical scheme, since there is a small error in the processing of the roller, after being detected by the outer diameter detection mechanism and the height detection mechanism, the same error rollers are placed in the same roller channel by the blanking mechanism, and then the distributing manipulator assembly moves and places the rollers in the same roller channel into the corresponding distributing box assemblies for separate collection.

[0047] In summary, the present application has at least one of the following beneficial technical effects:

[0048] The hardness detection mechanism, the outer diameter detection mechanism and the height detection mechanism are integrated on one device, and the transfer mechanism can move the rollers on the feeding mechanism to the hardness detection mechanism, and also move the rollers on the hardness detection mechanism to the outer diameter detection mechanism, and move the rollers on the outer diameter detection mechanism to the height detection mechanism, thereby improving the detection efficiency of the rollers;

[0049] The first positioning rod and the second positioning rod form two-point positioning, and the transfer mechanism can relatively accurately move the roller to the corresponding position. Then the rod driving member drives the rod to move and push the roller to move slightly, until the first positioning rod, the second positioning rod and the rod clamp and position the roller, at which time the outer diameter measurement can accurately measure the outer diameter of the roller;

[0050] The rollers detected by the outer diameter detection are transferred to the height detection groove by the transfer mechanism. With the rotation of the rotating disc, the rollers in the height detection groove are first detected by the height measurement assembly. The rollers with qualified height and outer diameter are transferred to the corresponding roller channel in the material distribution conveying belt by the blanking mechanism, and then transferred and placed in the corresponding material distribution box assembly by the material distribution mechanical arm assembly for separate collection. The unqualified products in height or outer diameter fall into the guide pipe from the blanking hole after rotating through the blanking mechanism, and are rolled out from the guide pipe for unified collection.

[0051] Each time the swing arm assembly moves the roller, the rotating disc is linked with the swing arm assembly to rotate through the cooperation of the ratchet and the gear teeth. After the rotating disc rotates, the driving wheel is driven to rotate to engage the teeth with the rack, so that the linkage plate drives the rotating assembly to descend and cooperate with the roller in the height detection groove. When the driving wheel rotates between the adjacent two teeth, the rotating assembly will rise under the action of the return spring for resetting. Thus, one swing arm action will generate two mechanical linkages of rotating disc rotation and rotating assembly descent, saving two driving sources. BRIEF DESCRIPTION OF DRAWINGS

The transfer mechanism 6 can move the roller on the feeding mechanism 2 to the position of the hardness detection mechanism 3 through swing arm movement to detect the hardness, and at the same time, the roller after the hardness detection is transferred to the position of the outer diameter detection mechanism 4 to detect the outer diameter of the roller, and the roller after the outer diameter detection is transferred to the position of the height detection mechanism 5 to detect the height. The finally qualified roller is transferred to the distributing mechanism 8 through the discharging mechanism 7, and the distributing mechanism 8 collects the rollers with the same error.

[0065] In combination Figure 1 Referring to Figure 2 and Figure 3 , the feeding mechanism 2 comprises a feeding track 21, a feeding rotating wheel 22, a blocking plate 23 and a feeding motor 24. The outer peripheral wall of the feeding rotating wheel 22 is uniformly and circumferentially spaced apart to be provided with a plurality of roller grooves 221, and the roller grooves 221 penetrate through the feeding rotating wheel 22 along the axial direction of the feeding rotating wheel 22.

The top of the outer diameter mechanism rack 41 also places a mark rack 46, and the mark rack 46 places a roller mark element, thereby providing a basic reference value for the measured roller.

[0068] Referring to Figure 2 With Figure 3 , the positioning assembly 42 and the top rod assembly 43 cooperate to clamp and position the roller, and then the outer diameter measurement assembly 44 measures the outer diameter size of the roller. When the roller is tilted when being transferred to the positioning assembly 42, the inclination sensor 45 will transmit a signal to the control system, and the control system will control the alarm to issue an alarm, and each detection mechanism will stop running, and the worker will put the roller in place, and then each detection mechanism will continue to operate.

The protective cover 442 is arranged on the diameter measurement probe 441 and is fixed on the top of the outer diameter mechanism rack 41 by bolts, thereby reducing the influence of other components on the measurement of the diameter measurement probe 441. The protective cover 442 has an open channel along the measurement direction of the diameter measurement probe 441, thereby not interfering with the measurement of the diameter measurement probe 441.

[0072] Referring to Figure 1 with Figure 4 , the height detection mechanism 5 includes a rotating disc assembly 51, a height measurement assembly 52 and a rotating disc driving assembly 53.

The height measurement probe 521 is installed on the suspended part of the mounting plate 522 above the rotating disc 512, and the height measurement probe 521 is opposite to the slot of the height detection groove 5121. That is, the roller is located directly below the height measurement probe 521 after the rotating disc 512 rotates.

When the roller after the height detection rotates to the blanking hole 51121 with the rotating disc 512, the hardness unqualified roller will enter the guide pipe through the blanking hole 51121 and roll out from the guide pipe for collection.

[0078] With reference to Figure 4 With Figure 5 The rotating shaft 531 is located between the two support vertical plates 5111, and the rotating shaft 531 passes through the support horizontal plate 5112 and is partially above the support horizontal plate 5112 and partially below the support horizontal plate 5112. The rotating shaft 531 is rotatably installed on the support horizontal plate 5112. The connecting rod rotating disc 532 is rotatably installed on the rotating shaft 531 and rotates around the rotating shaft 531 as the rotating shaft 531. The ratchet disc 535 and the rotating disc 512 are both sleeved on the rotating shaft 531 and are keyed connected with the rotating shaft 531, so that the ratchet disc 535 and the rotating disc 512 will rotate synchronously with the rotating shaft 531. The ratchet 536 is rotatably installed on the connecting rod rotating disc 532 and cooperates with the ratchet wheel, and the connecting rod rotating disc 532 will drive the ratchet wheel and the rotating disc 512 to rotate synchronously during the return process after each rotation.

The rotating plate 5321 is sleeved on the rotating shaft 531. The arc-shaped plate 5322 shields at least two adjacent height detection grooves 5121 in the rotating direction of the connecting rod rotating disc 532, so that when the roller is placed in the height detection groove 5121 by the transferring mechanism 6, the bottom of the roller abuts against the arc-shaped plate 5322, reducing the risk of interference of the roller with the arc-shaped plate 5322 when the arc-shaped plate 5322 reciprocatingly rotates with the rotating plate 5321. The extension rod 5323 protrudes from the ratchet disc 535 along its own extension, and the ratchet 536 is rotatably installed on the extension rod 5323 through a rotating shaft. The extension rod 5323 is connected with a tension spring 537 which drives the ratchet 536 to always abut against the ratchet disc 535. One end of the tension spring 537 is connected to one side of the ratchet 536 close to the ratchet disc 535, and the other end is connected to the extension rod 5323. The second connecting rod 534 is rotatably connected with the extension rod 5323.

The arc-shaped groove 51122 is concentrically arranged with the rotating plate 5321, and the arc-shaped groove 51122 is in communication with the height detection groove 5121. A plurality of balls 51123 are placed in the arc-shaped groove 51122, so that when the rotating disc 512 rotates, the rollers in the height detection groove 5121 abut against the balls 51123, becoming rolling friction, reducing the wear of the end surface of the roller.

[0081] The second connecting rod 534 is rotatably connected to a rotating block 538 on the side away from the extension rod 5323 through a rotating shaft 531, and the second connecting rod 534 and the rotating block 538 are rotatably connected in the horizontal direction.

[0092] Referring to Figure 6 With Figure 7 , the first bevel gear 732 is located below the support cross plate 5112 and is keyed to the rotating shaft 531 to rotate synchronously with the rotating shaft 531. The bottom of the blanking cross plate 712 is provided with a transmission vertical plate 737, which is fixedly installed on the base 1.

[0094] The size defective product collecting assembly 74 includes a blanking passage 741 and a waste collecting box 742, and the blanking passage 741 is fixed on the side wall of the blanking horizontal plate 712 by bolts. The waste collecting box 742 is placed on the base 1 and located at the discharge port of the blanking passage 741. The rotating rod 725 drives the size-unqualified roller to rotate above the blanking passage 741 and then releases the roller, so that the roller rolls into the collecting box from the blanking passage 741.

The rollers with the same outer diameter error are located in the same roller passage 8111 by the rotating rod 725.

[0097] The distributing box assembly 82 is composed of multiple collecting boxes 821, and the multiple collecting boxes 821 are located on both sides perpendicular to the conveying direction of the conveying belt 811 and are arranged at intervals, so that the rollers in the same roller passage 8111 can be placed in the same collecting box 821.

[0098] Referring to Figure 9The distribution mechanical arm assembly 83 is located above the conveying belt 811 and is installed on the side wall of the rack at the top of the base 1.

Then the rollers in the roller channel 8111 are grabbed and placed in the corresponding material collecting box 821.

[0099] The implementation principle of the roller automatic detection device is that the swing arm motor 614 drives the swing arm plate 613 to perform a reciprocating swing action, so that the adsorption assembly 62 moves the roller on the feeding rotating wheel 22 to the hardness detector 31 to detect the hardness; the roller on the hardness detector 31 is moved to the top of the outer diameter mechanism rack 41, and the first positioning rod 421, the second positioning rod 422 and the top rod 431 are clamped to detect the outer diameter; the roller on the top of the outer diameter mechanism rack 41 is moved to the height detection groove 5121, and the height measurement probe 521 detects the height of the roller by rotating the rotating disc 512.

[0100] After the rotating disc 512 rotates, the roller with qualified hardness is placed in the corresponding roller channel 8111 by rotating the rotating rod 725. Then the distribution mechanical arm assembly 83 moves the roller in the corresponding roller channel 811 to the corresponding material collecting box 821. The roller with unqualified hardness is collected by rolling out from the guide pipe.

[0101] In the process of the swing arm plate 613 swinging, the driving connecting rod rotating disc 532 is driven to rotate, the ratchet 536 drives the ratchet disc 535 and the rotating disc 512 to rotate, and then the roller in the height detection groove 5121 is rotated. When the rotating disc 512 rotates, the rotating shaft 531 rotates, the first bevel gear 732 and the second bevel gear 733 mesh to rotate the transmission shaft 734, then the transmission wheel 735 rotates, and the convex teeth 7351 and the rack 7361 on the linkage plate 736 mesh to drive the installation base plate 721 to descend, so that the adsorption assembly 62 on the rotating rod 725 can be adsorbed to the roller in the height detection groove 5121. When the convex teeth 7351 do not mesh with the rack 7361, the installation base plate 721 rises under the driving of the return spring 731, and then the roller in the height detection groove 5121 is pulled out. The above structure realizes multiple mechanical linkage.
