Description

Technical Field

[0001] This invention relates to an automatic feeding device based on visual recognition, specifically a fully automatic feeding device for tapered roller bearing retainers. Background Technology

[0002] In automated feeding systems, the stable conveying of materials and the accurate detection of bearing cages determine the quality of tapered roller bearing cages at the outlet. Currently, most cage feeding is done manually, which is prone to errors due to insufficient professional skills of some personnel and visual fatigue from long-term feeding and inspection. This makes it difficult to achieve efficient feeding of bearing cages and has defects such as large errors from manual intervention, slow speed, and outdated detection methods.

[0003] Chinese invention patent CN109973532B discloses a tapered roller bearing assembly machine, comprising: a worktable including a retainer feeding station, a retainer pushing station, a position detection station, a roller and inner ring assembly station, a roller assembly detection station, an assembly orientation station, and a riveting station; a retainer pushing mechanism for pushing the retainer; and a position detection mechanism for detecting whether the retainer is located at the center of the position detection station.

[0004] The problem is that the holder loading station, holder pushing station, and position detection station only realize holder loading and pushing, and the detection is only for posture detection, and does not involve monitoring the quality of holder products.

[0005] To improve the efficiency and precision required in the automatic feeding process and to promptly screen out substandard products, it is necessary to automate and monitor the tapered roller bearing retainer in real time during the feeding process. Summary of the Invention

[0006] This invention is a fully automatic feeding device for tapered roller bearing retainers. The device is used for the automated feeding of tapered roller bearing retainers and automatically completes sorting and recycling during real-time detection, realizing real-time detection and sorting and recycling of tapered roller bearing retainers.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical means:

[0008] An automatic feeding device for tapered roller bearing retainers includes a frame, on which are mounted a front-to-back transmission mechanism, a left-to-right transmission mechanism, a top-to-bottom transmission mechanism, a gripping module, a position scanning and detection mechanism, a falling module, and a conveying module, a recycling module, a tilting module, a material rising module, a sliding module, and a material placing mechanism located on the side of the frame.

[0009] The front and rear transmission mechanism drives the left and right transmission mechanisms to move in the front and rear directions;

[0010] The left and right transmission mechanism drives the up and down transmission mechanism to move in the left and right directions;

[0011] The up-and-down transmission mechanism drives the gripping module to move in the vertical direction;

[0012] The gripping module grips the bearing retainers stacked on the material placement mechanism and transports the bearing retainers to the falling module.

[0013] The position scanning and detection mechanism includes a support base, a camera integration mechanism, and a fixing base; it is fixed above the frame, acquires the conveying image of the bearing retainer, and transmits its position information to the control system.

[0014] The control system identifies the feeding position, conveying position, and conveying speed of the bearing retainer to ensure stable feeding quality.

[0015] The falling module delivers bearing retainers to the conveying module one by one;

[0016] The conveying module is equipped with a conveyor belt, which carries the bearing retainer transported by the falling module to the recovery module and the tilting module.

[0017] The recycling module is located on one side of the conveyor module. The recycling module includes a baffle three and a recycling slide. The recycling slide is inclined and its top end is connected to one side of the conveyor belt. The baffle three is located at the connection between the recycling slide and the conveyor belt. The baffle three causes the bearing retainers that are not up to size to slide off the conveyor belt onto the recycling slide. The bearing retainers that are up to size continue to be conveyed from the conveyor belt to the tilting module.

[0018] Dimensional non-compliance refers to a bearing retainer that is laid flat and conveyed with a height greater than the height of a qualified product. The recycling module blocks the non-qualified bearing retainer with baffle three and pushes it into the recycling chute for recovery, thus completing the bearing retainer screening process.

[0019] The tilting module is located at the end of the conveying module. The tilting module includes a partition, an arc-shaped groove, and a second slide rail. The partition is connected to the end of the conveyor belt and has a rotational gap between its bottom surface and the conveyor belt to prevent it from obstructing the rotation of the conveyor belt. The second slide rail is tilted and its top is connected to one side of the conveyor belt. An arc-shaped groove is provided on one side of the top of the second slide rail. The selected single bearing retainer is blocked by the partition and slides into the arc-shaped groove. Under the action of gravity and the support force of the arc-shaped groove on one side, the bearing retainer flips over, rotates 90 degrees from the flat position to the upright position, and rolls down along the second slide rail to the material rising module.

[0020] The material lifting module delivers the bearing retainer to the sliding module;

[0021] The sliding module receives the qualified bearing retainer conveyed by the material lifting module and delivers it to the subsequent processing equipment.

[0022] As a further improvement to this technical solution: the front and rear transmission mechanism includes a front and rear moving servo motor, a first power gear, and a first belt. The front and rear moving servo motors are located at both ends of the crossbeam and are connected to drive the first power gear. The first power gear meshes with the first belt, which is positioned along the top of the frame. When the front and rear moving servo motors operate, the first power gear moves along the first belt, thereby causing the crossbeam to move back and forth along the frame.

[0023] As a further improvement to this technical solution: the crossbeam is provided with a left and right transmission mechanism, which includes a left and right moving servo motor, a second power gear, and a second belt. The left and right moving servo motor is mounted on a feeding connecting seat on one side of the crossbeam. The left and right moving servo motor drives the second power gear, which meshes with the second belt. The second belt is connected to one side of the crossbeam. When the left and right moving servo motor works, the second power gear moves along the second belt, thereby causing the feeding connecting seat to move along the crossbeam in the left and right direction.

[0024] As a further improvement to this technical solution: the upper and lower transmission mechanism is connected and mounted on the loading connecting seat. The upper and lower transmission mechanism includes an upper and lower movement servo motor, a third power gear, a third belt, and a guide rail. The upper and lower movement servo motor is connected and mounted on the loading connecting seat, driving the third power gear. The third power gear meshes with the third belt, which is mounted on a vertical transmission rod. The guide rail is connected to the vertical transmission rod and slides in contact with the loading connecting seat. When the upper and lower movement servo motor operates, it causes the third power gear to move along the third belt, thereby driving the vertical transmission rod to rise or fall. The sliding contact between the guide rail and the loading connecting seat limits the movement of the vertical transmission rod, making the movement smoother.

[0025] As a further improvement to this technical solution: the gripping module is located at the bottom end of the vertical transmission rod, and includes a cylinder, a slide rail, a robotic arm, and a circular fixed platform; the cylinder, slide rail, and robotic arm are arranged in three sets at equal intervals in a triangular pattern and fixed on the circular fixed platform; the cylinder provides power, and the robotic arm extends along the slide rail one by one to grip the bearing retainers stacked on the material placement mechanism. The gripping module realizes the gripping function of the bearing retainers and transports them.

[0026] As a further improvement to this technical solution: the falling module is located at the material outlet at the bottom of the stacking cavity above the feed end of the conveying module. Three falling modules are evenly spaced along the circumference of the stacking cavity, each with the same structure. Each falling module is equipped with a stepper motor, gears, a fixed bracket, and a worktable. The stepper motor is connected to the worktable, which is fixedly connected to the stacking cavity. The stepper motor drives the gears, and the three gears rotate to clamp the bearing retainers in the stacking cavity and push them downward to the conveying module. The gears are driven to rotate sequentially to push the stacked bearing retainers.

[0027] The drop module converts the stacked bearing retainers into a single state, facilitating subsequent retainer testing.

[0028] As a further improvement to this technical solution: the conveying module includes a servo motor, a conveyor belt, and a roller; the conveyor belt is connected to two spaced rollers, one of which is driven by a servo motor, and the conveyor belt conveys the bearing retainer to the recycling module and the tilting module.

[0029] As a further improvement to this technical solution: the material lifting module includes a lowering support platform, a second servo motor, a second roller, a transmission belt, a conveyor belt, a first vertical baffle, and a second vertical baffle; the lowering support platform is evenly connected to the conveyor belt, and the conveyor belt is connected to two second rollers, one of which is driven to rotate by the second servo motor via the transmission belt, thereby driving the conveyor belt to rotate; the conveyor belt is vertically arranged, and its bottom end mates with the discharge port at the bottom end of the slide rail of the tilting module; the width of the lowering support platform is smaller than that of the tapered roller bearing retainer. The width is such that a portion of the tapered roller bearing retainer, which is placed upright on the lower slide support, protrudes outside the lower slide support; a vertical baffle is provided on the opposite side of the conveyor belt, and a movement gap is provided between the vertical baffle and the lower slide support; the lower slide support is inclined, with the higher end facing the tilting module as the feed end and the lower side as the discharge end; a vertical baffle is provided at the lower end of the lower slide support, and a movement gap is provided between the vertical baffle and the lower slide support; a discharge port for the tapered roller bearing retainer to roll out is provided at the top of the vertical baffle.

[0030] When the tapered roller bearing retainer rolls from the tilting module onto the sliding support, it is blocked by the second vertical baffle. The tapered roller bearing retainer has a conveyor belt on one side and a first vertical baffle on the other. The conveyor belt uses the sliding support to transport the tapered roller bearing retainer upward. When it reaches the discharge port on the second vertical baffle, it rolls out from the sliding support through the discharge port under the action of gravity and enters the next process.

[0031] To protect the tapered roller bearing retainer, the two vertical baffles are provided with an anti-collision layer on the inner side of the sliding support, and the anti-collision layer is made of elastic cushioning material.

[0032] As a further improvement to this technical solution: the material rising module is provided with a baffle four at its top, the height of the baffle four corresponds to the discharge port, the baffle four is set between the vertical baffle one and the sliding support platform and is located on the higher side of the sliding support platform; the width of the sliding support platform is less than the width of the tapered roller bearing retainer, so that a part of the tapered roller bearing retainer protrudes from the sliding support platform and extends toward the vertical baffle one; when the tapered roller bearing retainer is conveyed to the baffle four, the part of it extending toward the vertical baffle one touches the baffle four, causing the tapered roller bearing retainer to roll from the sliding support platform through the discharge port and enter the next process.

[0033] By setting baffle four, it can be ensured that under certain circumstances, the tapered roller bearing retainer that has not rolled out of the sliding support due to gravity will be rolled out by the thrust of baffle four.

[0034] As a further improvement to this technical solution: the material placement mechanism is placed below the gripping module. The material placement mechanism includes a base and a retainer placement frame. The lower end of the retainer placement frame is equipped with a pulley. The retainer placement frame is slidably removed or placed in the base through the pulley. The retainer placement frame can move for replacement. Each stacked bearing retainer is fixed in position by three columns arranged in a triangular pattern, which can be accurately positioned. The base is provided with a pulley groove. The opening of the pulley groove is Y-shaped, which makes it easier for the pulley to roll into the pulley groove.

[0035] The bearing retainer moves through front-to-back transmission mechanism, left-to-right transmission mechanism, and up-down transmission mechanism. The gripping module, position scanning and detection mechanism, falling module, and conveying module work together to feed the bearings. Unqualified bearing retainers are recovered by the recycling module, while qualified products are adjusted in direction by the tilting module, lifted by the material lifting module, and then transported to the processing equipment by the sliding module. The entire bearing retainer feeding process is completed.

[0036] Both the conveying module and the descent module are equipped with photoelectric proximity switches. The photoelectric proximity switches check whether the bearing retainer is being conveyed, thereby controlling the descent module or the material rising module to temporarily stop working, which facilitates the control of the bearing retainer conveying.

[0037] The working principle and process of some mechanisms in this utility model are explained below:

[0038] The front-to-back transmission mechanism, left-to-right transmission mechanism, and up-down transmission mechanism enable the bearing retainer to move along three mutually perpendicular dimensions to transfer the bearing retainer for inspection.

[0039] The working principle and process of this invention are as follows:

[0040] The bearing retainers to be tested are placed on the material placement mechanism. The front-to-back, left-to-right, and up-down transmission mechanisms work together to enable the gripping module to grasp and move the bearing retainers on the material placement mechanism. The position scanning and detection mechanism detects the image information of the bearing retainers being transported and the camera processing the image information to determine whether they have moved to the appropriate position. The gripping module then lowers the material to the falling module, which then places the stacked bearing retainers one by one onto the conveyor belt of the lower conveying module for transport. The conveyor belt is equipped with photoelectric proximity switches to detect the feeding progress. When the number of retainers on the conveyor belt reaches a certain limit, the falling stops. The bearing retainers being transported pass through the recycling module. Unqualified bearing retainers are blocked by baffle three and pushed into the slide for recycling, thus completing the bearing retainer screening work. The qualified bearing retainer is transported to the tilting module by a conveyor belt. Under the action of gravity and the support force of the arc-shaped groove on one side, the bearing retainer flips over, rotates 90 degrees from a flat position, and rolls into the slide rail two after becoming an upright position. From the slide rail two, it enters the material lifting module, which lifts the bearing retainer. After reaching the designated position, the bearing retainer is blocked by the baffle four, causing the retainer to roll down to the sliding module. On the sliding module, the first photoelectric proximity switch detects the feeding progress of the retainer, and the second photoelectric proximity switch detects whether the exit position has been reached, realizing closed-loop control of bearing retainer feeding detection. After feeding is completed, it is conveyed to the subsequent processing equipment for processing.

[0041] The advantages of this embodiment are:

[0042] (1) By setting up a position scanning detection mechanism, the camera can capture clear and complete images, which improves the image acquisition quality and target recognition accuracy of the machine during the bearing retainer detection and feeding process.

[0043] (2) By setting up front and rear transmission mechanisms, left and right transmission mechanisms, and up and down transmission mechanisms, precise movement in the X, Y, and Z directions is achieved, thereby realizing precise movement of the bearing retainer.

[0044] (3) By setting up a recycling module, baffle three, and recycling slide, the bearing retainer can be detected, screened and recycled in real time, which greatly improves sorting efficiency and reduces manual labor input. Attached Figure Description

Detailed Implementation

[0063] The present invention will be further described below with reference to the embodiments.

[0064] Reference Figures 1-5 As can be seen, the fully automatic feeding device for tapered roller bearing retainers of this utility model consists of a frame 2, a front-to-back transmission mechanism 1, a left-to-right transmission mechanism 3, a top-to-bottom transmission mechanism 4, a gripping module 5, a position scanning and detection mechanism 6, a falling module 7, and a conveying module 8, a recycling module 9, a tilting module 10, a material rising module 11, a sliding module 12, and a material placing mechanism 13 arranged on the side of the frame 2.

[0065] See Figure 2 It can be seen that the bearing retainer is initially placed at the material placement mechanism 13 to transport and supply materials.

[0066] See Figure 3 , Figure 6 , Figure 7 , Figure 8 It is understood that the front-to-back transmission mechanism 1 is equipped with a front-to-back moving servo motor 101, a drive gear 102, and a belt 103. The front-to-back moving servo motor 101 is located at both ends of the crossbeam and is connected to drive the drive gear 102. The drive gear 102 meshes with the belt 103, which is located along the top of the frame. When the front-to-back moving servo motor 101 operates, it causes the drive gear 102 to move along the belt 103, thereby causing the crossbeam to move back and forth along the frame.

[0067] The crossbeam is equipped with a left-right transmission mechanism 3. The left-right transmission mechanism 3 is equipped with a front-back moving servo motor 301, a second power gear 302, and a second belt 303. The front-back moving servo motor 301 is mounted on a feeding connecting seat on one side of the crossbeam. The front-back moving servo motor 301 drives the second power gear 302, which meshes with the second belt 303. The second belt 303 is connected to one side of the crossbeam. When the front-back moving servo motor 301 works, it causes the second power gear 302 to move along the second belt 303, thereby causing the feeding connecting seat to move along the crossbeam in the left-right direction.

[0068] The upper and lower transmission mechanism 4 is connected and mounted on the loading connecting seat. The upper and lower transmission mechanism 4 includes an upper and lower movement servo motor 401, a power gear 402, a belt 403, and a guide rail 404. The upper and lower movement servo motor 401 is connected to the loading connecting seat and drives the power gear 402. The power gear 402 meshes with the belt 403, which is mounted on a vertical transmission rod. The guide rail 404 is connected to the vertical transmission rod and slides in contact with the loading connecting seat. When the upper and lower movement servo motor 401 operates, it causes the power gear 402 to move along the belt 403, thereby driving the vertical transmission rod to rise or fall. The guide rail 404 slides in contact with the loading connecting seat, limiting the movement of the vertical transmission rod and making the movement smoother.

[0069] See Figure 9 It is understood that the gripping module 5 is located at the bottom end of the vertical transmission rod. The gripping module 5 includes a cylinder 501, a slide rail 502, a robotic arm 503, and a circular fixed platform 504. The cylinder 501, slide rail 502, and robotic arm 503 are arranged in three sets at equal intervals in a triangular pattern and fixed on the circular fixed platform 504. The cylinder 501 provides power, and the robotic arm 503 extends along the slide rail 502 to grip the bearing retainers stacked on the material placement mechanism 13. The gripping module 5 realizes the gripping function of the bearing retainers and performs the transportation of the bearing retainers.

[0070] The front-to-back transmission mechanism 1, the left-to-right transmission mechanism 3, the up-to-down transmission mechanism 4, and the gripping module 5 clamp and transfer the bearing retainer from the material placement mechanism 13 to the falling module 7.

[0071] See Figure 2 It is understood that the position scanning and detection mechanism 6 includes a support base 601, a camera integration mechanism 602, and a fixing base 603; it is fixed above the frame 2, acquires the conveying image of the bearing retainer, and transmits its position information to the control system. The control system identifies the feeding position, conveying position, and conveying speed of the bearing retainer to ensure stable feeding quality.

[0072] See Figure 3 , Figure 4 , Figure 10 It is understood that the falling module 7 is located at the material outlet at the bottom of the stacking cavity above the feeding end of the conveying module 8. Three falling modules 7 are evenly spaced along the circumference of the stacking cavity, each with the same structure. Each falling module 7 is equipped with a stepper motor 701, gears 702, a fixed bracket 703, and a worktable 704. The stepper motor 701 is connected to the worktable 704, which is fixedly connected to the stacking cavity. The stepper motor 701 drives the gears 702. The three gears 702 rotate to clamp the bearing retainers in the stacking cavity and push them downwards towards the conveying module 8. The gears 702 are driven to rotate sequentially, pushing the stacked bearing retainers. The falling module 7 converts the stacked bearing retainers into a single state, facilitating subsequent retainer inspection.

[0073] See Figure 4 , Figure 11 It is known that the conveying module 8 includes a servo motor 801, a conveyor belt 802, and a roller 803; the conveyor belt 802 is connected to two rollers 803 that are spaced apart, one of which is driven by a servo motor 801; the conveyor belt 802 conveys the bearing retainer and transports the bearing retainer to the recycling module 9 and the tilting module 10.

[0074] See Figure 12 It is understood that the recycling module 9 is located on one side of the conveying module 8. The recycling module 9 includes a baffle 901 and a recycling slide 902. The recycling slide 902 is inclined and its top end is connected to one side of the conveyor belt 802. The baffle 901 is located at the connection between the recycling slide 902 and the conveyor belt 802. The baffle 901 causes the bearing retainers that are not up to size to slide off the conveyor belt 802 onto the recycling slide 902. "Not up to size" means that the height of the bearing retainer being conveyed horizontally is greater than the height of the qualified product. The recycling module 9 blocks the unqualified bearing retainers with the baffle 901 and pushes them into the slide 902 for recycling, thus completing the bearing retainer screening process.

[0075] See Figure 13It is known that the tilting module 10 is located at the end of the conveying module 8. The tilting module 10 includes a partition 1001, an arc-shaped groove 1002, and a second slide rail 1003. The partition 1001 is connected to the end of the conveyor belt 802 and there is a rotational gap between its bottom surface and the conveyor belt 802 to prevent it from obstructing the rotation of the conveyor belt 802. The second slide rail 1003 is tilted and its top end is connected to one side of the conveyor belt 802. An arc-shaped groove 1002 is provided on one side of the top end of the second slide rail 1003. The single bearing retainer that has passed the screening is blocked by the partition 1001 and slides into the arc-shaped groove 1002. Under the action of gravity and the support force of the arc-shaped groove 1002 on one side, the bearing retainer flips over, rotates 90 degrees from the flat position to the upright position, and rolls down along the second slide rail 1003 to the material rising module 11.

[0076] See Figure 14 The material lifting module 11 includes a lower sliding support 1101, a second servo motor 1102, a second roller 1103, a transmission belt 1104, a conveyor belt 1105, a first vertical baffle 1107, and a second vertical baffle 1108. The lower sliding support 1101 is evenly connected to the conveyor belt 1105, and the conveyor belt 1105 is connected to two second rollers 1103. One of the rollers 1103 is driven to rotate by the second servo motor 1102 through the transmission belt 1104, thereby driving the conveyor belt 1105 to rotate. The conveyor belt 1105 is vertically arranged, and its bottom end mates with the discharge port at the bottom end of the slide rail 1003 of the tilting module 10. The width of the lower sliding support 1101 is smaller than that of the tapered roller shaft. The width of the retainer allows a portion of the tapered roller bearing retainer, which is placed on the lower slide support 1101, to protrude outside the lower slide support 1101. A vertical baffle 1107 is provided on the opposite side of the conveyor belt 1105. A movement gap is provided between the vertical baffle 1107 and the lower slide support 1101. The lower slide support 1101 is inclined, with the higher end facing the tilting module 10 as the feed end and the lower end as the discharge end. A vertical baffle 2 1108 is provided at the lower end of the lower slide support 1101 of the conveyor belt 1105. A movement gap is provided between the vertical baffle 2 1108 and the lower slide support 1101. A discharge port 1109 for the tapered roller bearing retainer to roll out is provided at the top of the vertical baffle 2 1108.

[0077] When the tapered roller bearing retainer rolls from the tilting module 10 onto the lower slide support 1101, it is blocked by the vertical baffle 1108. The tapered roller bearing retainer is supported by a conveyor belt 1105 and a vertical baffle 1107 on both sides. The conveyor belt 1105 uses the lower slide support 1101 to transport the tapered roller bearing retainer upward. When it reaches the discharge port 1109 on the vertical baffle 1108, it rolls out from the lower slide support 1101 through the discharge port 1109 under the action of gravity and enters the next process.

[0078] To protect the tapered roller bearing retainer, the inner side of the vertical baffle 1108 facing the sliding support 1101 is provided with an anti-collision layer, which is made of elastic cushioning material.

[0079] The material lifting module 11 is provided with a baffle 4 1106 at its top. The height of the baffle 4 1106 corresponds to the discharge port 1109. The baffle 4 1106 is located between the vertical baffle 1107 and the sliding support 1101 and is located on the higher side of the sliding support 1101. The width of the sliding support 1101 is smaller than the width of the tapered roller bearing retainer, so that a part of the tapered roller bearing retainer protrudes from the sliding support 1101 and extends toward the vertical baffle 1107. When the tapered roller bearing retainer is conveyed to the baffle 4 1106, the part of it extending toward the vertical baffle 1107 touches the baffle 4 1106, causing the tapered roller bearing retainer to roll from the sliding support 1101 through the discharge port 1109 and enter the next process.

[0080] By setting baffle four 1106, it can be ensured that, under certain circumstances, the tapered roller bearing retainer that has not rolled out of the sliding support 1101 due to gravity will be rolled out by the thrust of baffle four 1106. See also Figure 1-5 It can be seen that the sliding module 12 receives the qualified bearing retainer conveyed by the material lifting module 11 and conveys it to the subsequent processing equipment.

[0081] See Figure 15 It is known that the material placement mechanism 13 is placed below the gripping module 5. The material placement mechanism 13 includes a base 1301 and a retainer placement frame 1302. The retainer placement frame 1302 has a pulley at its lower end. The retainer placement frame 1302 is slidably removed or placed in the base 1301 through the pulley. The retainer placement frame 1302 can move to replace the bearing retainer. Each stacked bearing retainer is fixed in position by three columns in a triangular arrangement, which can be accurately positioned. The base 1301 is provided with a pulley groove. The opening of the pulley groove is Y-shaped, which makes it easier for the pulley to roll into the pulley groove.

[0082] The bearing retainer moves via the front-to-back transmission mechanism 1, the left-to-right transmission mechanism 3, and the up-and-down transmission mechanism 4. The gripping module 5, the position scanning and detection mechanism 6, the falling module 7, and the conveying module 8 work together to feed the bearing retainer. Unqualified bearing retainers are recovered by the recycling module 9, and qualified products are adjusted in direction by the tilting module 10 and lifted by the material lifting module 11. They are then conveyed to the processing equipment by the sliding module 12. The entire bearing retainer feeding process is completed.

[0083] Both the conveying module 8 and the sliding module 12 are equipped with photoelectric proximity switches 14. The photoelectric proximity switches 14 check whether the bearing retainer is being conveyed, thereby controlling the falling module 7 or the material rising module 11 to temporarily stop working, so as to facilitate the control of the bearing retainer conveying.

[0084] The working principle and process of some mechanisms in this invention are explained below:

[0085] The front-to-back transmission mechanism 1, the left-to-right transmission mechanism 3, and the up-to-down transmission mechanism 4 enable the bearing retainer to move along three mutually perpendicular dimensions to transfer the bearing retainer for inspection.

[0086] The working principle and process of this invention are as follows:

[0087] The bearing retainers to be tested are placed on the material placement mechanism 13. The front-to-back transmission mechanism 1, the left-to-right transmission mechanism 3, and the up-and-down transmission mechanism 4 work together to make the gripping module 5 grip and move the bearing retainers on the material placement mechanism 13. The position scanning detection mechanism 6 detects the acquisition of the bearing retainer conveying image information and the recognition and processing of the camera to determine whether it has moved to the appropriate position. The gripping module 5 puts the material down to the falling module 7. The falling module 7 puts the stacked bearing retainers one by one onto the conveyor belt 802 of the lower conveying module 8 for transportation. The conveyor belt 802 is equipped with a photoelectric proximity switch 14 to detect the feeding progress. When the number of retainers on the conveyor belt 802 reaches the limit, the falling stops. The bearing retainers in the transportation pass through the recycling module 9. The unqualified bearing retainers are blocked by the baffle 3 901 and pushed into the slide 902 for recycling. The bearing retainer screening work is completed in this way. The qualified bearing retainer is transported by conveyor belt to the tilting module 10. Under the action of gravity and the support of the arc-shaped groove 1002 on one side, the bearing retainer flips over, rotates 90 degrees from the flat position, and rolls into the slide rail 1003. From the slide rail 1003, it enters the material lifting module 11. The material lifting module 11 lifts the bearing retainer. After reaching the designated position, the bearing retainer is blocked by the baffle 4, causing the retainer to roll down to the sliding module. The first photoelectric proximity switch 14 on the sliding module 12 detects the progress of the retainer feeding, and the second photoelectric proximity switch 14 detects whether the exit position has been reached, realizing closed-loop control of bearing retainer feeding detection. After feeding is completed, it is conveyed to the subsequent processing equipment for processing.

[0088] The advantages of this embodiment are:

[0089] First: By setting up the position scanning detection mechanism 6, the camera can capture clear and complete images, which improves the image acquisition quality and target recognition accuracy of the machine during the bearing retainer detection and feeding process.

[0090] Second: By setting up a front-to-back transmission mechanism 1, a left-to-right transmission mechanism 3, and an up-to-down transmission mechanism 4, precise movement in the X, Y, and Z directions is achieved, thereby realizing precise movement of the bearing retainer.

[0091] Third: By setting up recycling module 9, baffle 3 901, and recycling slide 902, the bearing retainer can be detected, screened and recycled in real time, which greatly improves sorting efficiency and reduces manual labor input.

[0092] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent structural changes made based on the content of the present utility model specification and drawings are included within the scope of the present utility model.
