Description

Technical Field

[0001] This invention relates to the field of bearing manufacturing technology, and in particular to a bearing cage assembly device. Background Technology

[0002] Bearings are crucial basic components in mechanical equipment, and their performance directly affects the precision, lifespan, and reliability of the machine tool. The cage, as one of the core components of a bearing, is mainly used to isolate and guide the rolling elements (such as balls) and prevent them from colliding with each other, ensuring smooth bearing operation. Bearing assemblies with upper and lower cages and intermediate balls are widely used in the automotive, precision machine tool, and aerospace industries.

[0003] Traditional cage assembly methods for this type of bearing primarily rely on manual labor or semi-automated equipment. During manual assembly, workers must manually insert each ball into the pocket of the lower cage, and then manually align and press the upper cage together. This method is not only inefficient and labor-intensive, but also heavily dependent on worker skill. It is prone to problems such as missing or incorrect ball installation, or misalignment of the riveting points between the upper and lower cages due to visual fatigue or operational errors. These issues directly affect the bearing's dynamic balance, noise, and lifespan, making it difficult to guarantee consistent product quality. Summary of the Invention

[0010] Preferably, the adjusting base includes a rotating seat rotatably mounted on the worktable, the rotating seat being driven by a geared motor; an annular groove is provided on the rotating seat, and a lifting ring is movably arranged in the vertical direction within the annular groove, with a lifting rod driven by a lifting cylinder connected below the lifting ring; a second camera is provided at the center of the rotating seat; the geared motor and the lifting cylinder are both controlled by the control platform, and the second camera transmits the acquired image signals to the control platform.

[0015] S: Lower cage unloading and positioning: The control platform controls the lower cage storage and unloading mechanism to push out a single lower cage, and controls the transfer mechanism to push it onto the adjusting base;

[0016] S: Ball assembly: The control platform controls the shifting cylinder of the ball storage and unloading mechanism to move the unloading hopper to the unloading position, and simultaneously controls the unloading motor and the reduction motor of the adjusting base to work together to load the balls into each pocket of the lower retainer in sequence.

[0017] S: Upper cage pick-up and angle correction: The control platform controls the picking mechanism to pick up and transport the upper cage to the preparatory position, and at the same time calls up the images of the first camera and the second camera for comparison. Based on the comparison result, the control motor is controlled to fine-tune the angle of the lower cage. After the angle is aligned, the picking mechanism is controlled to lower the upper cage.

[0018] S: Compression forming: The control platform controls the compression mechanism to descend and complete the compression, and monitors the feedback signal of the pressure sensor;

[0019] S: Finished product unloading: After pressing, the control platform sequentially controls the lifting cylinder of the adjusting base to lift the finished product, and controls the transfer mechanism to push the finished product into the collection box to complete one assembly cycle.

[0020] The beneficial effects of this invention are:

[0021] This invention constructs a complete automated assembly line by arranging a material handling mechanism, a storage and unloading mechanism, a transfer mechanism, a pressing mechanism, and a core control platform. From the automatic supply of upper and lower retainers, the precise quantitative placement of ball bearings, the automatic transfer of components, to the pressing and collection of the final product, the entire process requires no manual intervention and is executed in a programmed and coordinated manner by the control platform. This greatly improves assembly efficiency, reduces labor costs and labor intensity, and is suitable for large-scale continuous production.

[0022] In this invention, images of the upper and lower cages are acquired by a first camera and a second camera, respectively. These images are then processed in real-time by a vision algorithm within the control platform, which calculates the angle deviation and drives the adjusting base to perform high-precision rotational compensation. This image-based closed-loop feedback control completely solves the problem of misalignment of the riveting points or positioning marks of the upper and lower cages in traditional methods, achieving alignment accuracy at the arcsecond level. Simultaneously, the pressure sensor integrated into the pressing mechanism feeds back the pressing force to the control platform in real time, enabling precise force control during the pressing process. This avoids over-pressurization or insufficient pressing force, further improving the quality and reliability of the finished bearing.

[0023] In this invention, a control platform is responsible for executing the action sequence and processing information from multiple sensors, including vision and pressure sensors, in real time, achieving process monitoring and adaptive adjustment. This allows visual alignment to compensate for minor machining errors in the parts themselves; force-controlled pressing can adapt to normal material fluctuations. This intelligent control method improves the equipment's adaptability to different batches of parts, reducing failures or scrap rates caused by part variations. Simultaneously, the fully automated process reduces human intervention, lowering the risk of equipment damage or production interruptions due to human error, and improving the stability and reliability of equipment operation.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Reference Figure 1-9 A bearing cage assembly device mainly includes a workbench 1, a control platform 11, and multiple functional mechanisms arranged along a specific workstation on the surface of the workbench 1.

[0044] The workbench 1 serves as the supporting base and assembly plane for the entire device. Its surface is precision-machined to ensure the reference accuracy of the installation of each mechanism. At the rear end of the workbench, from left to right, the material handling mechanism 2, the upper retainer storage cylinder 3, the ball bearing storage and unloading mechanism 4, and the lower retainer storage and unloading mechanism 5 are fixedly installed. At the front end of the workbench, from left to right, the finished product collection area 6, the upper and lower retainer pressing areas, and the lower retainer discharge area 7 are defined. A pressing mechanism 8 is installed directly above the pressing area, and an adjustable base 9 that can be adjusted in angle and height is provided directly below it. Through the above workstations, a transfer mechanism 10 is provided on the workbench to synchronously push parts between the workstations. The control platform 11 is usually installed in the electrical cabinet or to the side of the workbench 1 and is connected to all the above-mentioned motors, cylinders, sensors, cameras, and other electrical control components via cables and a bus system.

[0045] The following provides a detailed description of each organization and its collaborative relationship with the control platform 11:

[0046] 1. Material handling mechanism 2 and upper retainer storage cylinder 3

[0047] The material handling mechanism 2 is used to pick up a single upper retainer from the upper retainer storage cylinder 3 and precisely transfer it above the adjusting base 9. It includes a first connecting frame 201 fixed to the table surface. A first horizontal moving mechanism 202, such as a lead screw slide driven by a servo motor, is mounted on the bottom of the first connecting frame 201, and its moving direction is parallel to the length direction of the worktable. A lifting mechanism 203, such as a pen-shaped cylinder, is mounted on the slider of the first horizontal moving mechanism 202. The lower end of the piston rod of the lifting mechanism 203 is connected to an L-shaped device plate 204. A second horizontal moving mechanism 205, such as a short-stroke cylinder, is mounted on the outside of the L-shaped device plate 204, and its piston rod passes horizontally through the L-shaped device plate 204, with its end connected to a material handling suction cup 206 for adsorbing the upper retainer. The material handling suction cup 206 is connected to a vacuum generator. The upper retainer storage cylinder 3 is a vertical cylinder, and a push plate 301 is slidably mounted on its bottom. The push plate 301 is driven to move up and down by a feeding cylinder 302 mounted directly below it. The control platform 11 controls the entire material handling process through program logic: First, it controls the feeding cylinder 302 to lift and push the bottom one of the stacked upper retainers upward to the predetermined material handling height; then, it controls the first horizontal moving mechanism 202, the second horizontal moving mechanism 205 and the lifting mechanism 203 to work together to drive the material handling suction cup 206 to move above the upper retainer and start vacuum adsorption; finally, the mechanisms move in reverse to transfer the picked-up upper retainer to the preparation station.

[0048] 2. Ball bearing storage and unloading mechanism 4

[0049] This mechanism is used to quantitatively and individually feed balls into pre-positioned lower retainer pockets. It includes two symmetrically fixed L-shaped connecting frames 401 on a platform, which together support a ball storage cylinder 402. A discharge port 403 is formed at the bottom edge of the storage cylinder 402, and a rotatable discharge wheel 404 is mounted thereon. The discharge wheel 404 has a notch 405 on its circumference that matches the size of the balls. A discharge hopper 406, which can move back and forth, is slidably connected to the discharge port 403. The shaft of the discharge wheel 404 is connected to a first bevel gear 407, which meshes with a second bevel gear 408. The second bevel gear 408 is connected to a discharge motor 409 (such as a stepper motor) via a drive shaft. A displacement cylinder 410 is mounted on one of the L-shaped connecting frames 401, and its piston rod is connected to the discharge hopper 406. The control platform 11 controls the feeding process: The feeding motor 409 is started, driving the feeding wheel 404 to rotate. When the notch 405 rotates to align with the feeding port 403, a ball falls into the notch. Continuing to rotate, the ball is carried downwards and falls into the stationary feeding hopper 406. Then, the control platform 11 controls the displacement cylinder 410 to extend, moving the feeding hopper 406 carrying the single ball to directly above the current target pocket on the lower retainer (located on the adjusting base 9). The ball falls into the pocket due to gravity. During this process, the control platform 11 must be strictly synchronized with the rotation of the adjusting base 9.

[0050] 3. Lower cage storage and unloading mechanism 5

[0051] This mechanism is used to systematically output individual lower retainers. It includes a storage cylinder 501 vertically fixed to the table surface, with a transverse moving groove 502 at its bottom. A pusher plate 503 is slidably installed within the moving groove 502. The front end of the pusher plate 503 has an arc-shaped groove 504 that matches the curvature of the inner wall of the storage cylinder 501. A pusher cylinder 505 is installed at the bottom of the worktable 1, with its piston rod connected to the pusher plate 503. The control platform 11 controls the operation of the pusher cylinder 505: when the cylinder extends, the pusher plate 503 moves forward, and its arc-shaped groove 504 precisely supports the bottommost lower retainer in the stack, pushing it out from the front of the storage cylinder 501 and placing it in a preset initial position on the table surface (lower retainer discharge area 7), waiting for the transfer mechanism 10 to push it away.

[0052] 4. Pressing mechanism 8

[0053] The pressing mechanism 8 is used to press the upper and lower retainers and the intermediate ball bearings into place. It includes a second connecting frame 801 fixed on the worktable 1. A pressing cylinder 802 (such as a servo pressure cylinder) is mounted on the top of the second connecting frame 801, with its piston rod passing vertically downward through the second connecting frame 801 and connected to a pressing plate 803 at its end. A pressure sensor 804 (such as a strain gauge sensor) is embedded in the bottom of the pressing plate 803 for real-time monitoring of the pressing force. A first camera 805 (such as an industrial CCD camera) is also mounted at the center of the bottom of the pressing plate 803. After receiving a signal indicating that the angle alignment is complete, the control platform 11 controls the pressing cylinder 802 to descend and perform the pressing operation. The pressure sensor 804 feeds back the real-time force value to the control platform 11, which can then perform precise control according to a preset pressure curve to achieve constant force or graded pressing, preventing overpressure damage to the product. The first camera 805 is also triggered by the control platform 11 to capture images of the lower state.

[0054] 5. Adjustable base 9

[0055] The adjusting base 9 is the core component for achieving precise alignment in this device. It includes a rotating base 901 rotatably mounted on the worktable 1 via bearings. The rotating base 901 is driven to rotate by a geared motor 902 (such as a servo motor with a reducer). An annular groove 903 is formed on the upper surface of the rotating base 901 to accommodate the lower cage and balls. A lifting ring 904 is coaxially arranged within the annular groove 903, and the lifting ring 904 can move vertically within the annular groove 903. A lifting rod 906 is connected below it, and the lifting rod 906 is driven by a lifting cylinder 905. A second camera 907 is installed at the central through hole of the rotating base 901, with the lens facing upwards. The control platform 11 performs multi-task coordination for this mechanism: During the ball assembly stage, it controls the geared motor 902 to perform intermittent indexing rotation, so that the pockets of the lower cage are sequentially aligned with the ball unloading positions; during the upper cage alignment stage, it receives image signals from the first camera 805 (capturing the lower cage with balls installed on the rotary seat) and the second camera 907 (capturing the upper cage adsorbed by the suction cup 206), identifies the angles of the preset rivet points or positioning marks on the upper and lower cages through the built-in image processing algorithm, calculates the rotation angle that needs to be compensated, and then sends a command to the geared motor 902 to drive the rotary seat 901 to fine-tune the rotation, so that the angles of the upper and lower cages are completely aligned. After pressing is completed, it controls the lifting cylinder 905 to move, and lifts the finished product from the annular groove 903 through the lifting ring 904 for easy transfer.

[0056] 6. 10 transshipment facilities

[0057] The transfer mechanism 10 is responsible for moving components between fixed workstations. It includes three transfer push rods 1001 located on the same horizontal line, which are fixed to the same connecting rod 1002. The connecting rod 1002 is driven by a transfer cylinder 1003 mounted on the bottom of the worktable 1, and can reciprocate along the length of the worktable. The control platform 11 controls the extension and retraction of the transfer cylinder 1003, thereby synchronously pushing components located at different workstations into the next process: for example, pushing the lower retainer from the discharge area 7 to the adjusting base 9; or pushing the pressed finished product from the adjusting base 9 into the collection box 601 in the finished product collection area 6.

[0058] 7. Control Platform 11

[0059] The control platform 11 is the command center of the entire device. In this embodiment, it is preferably an integrated control system based on a programmable logic controller (PLC) or an industrial computer (IPC). This platform integrates motion control cards, I / O modules, vision processing software, etc. It sends precise action command sequences to the drivers or solenoid valves of each motor and cylinder through pre-programmed automated program logic. Simultaneously, it acquires analog signals from the pressure sensor 804, switch signals from each position sensor, and processes digital image signals from the first camera 805 and the second camera 907 in real time. Based on this feedback information, the control platform 11 performs logical judgments and closed-loop control to ensure seamless and reliable connection and precision in all stages, including material handling, unloading, transfer, alignment, pressing, and finishing, forming a complete automated assembly cycle.

[0060] The working principle and assembly process of this invention are as follows (coordinated and executed by the control platform 11):

[0061] Initialization and Lower Holder Loading: The device is started, and the control platform 11 initializes each mechanism. First, the pusher cylinder 505 of the lower holder storage and unloading mechanism 5 is activated to push a lower holder to the discharge area 7. Next, the transfer cylinder 1003 of the transfer mechanism 10 is activated to push the lower holder into the annular groove 903 of the rotating seat 901 of the adjusting base 9 via the transfer push rod 1001 for positioning.

[0062] Automatic ball bearing assembly: The control platform 11 controls the shifting cylinder 410 of the ball bearing storage and unloading mechanism 4 to move the unloading hopper 406 to the ready position. Then, it synchronously controls the unloading motor 409 and the reduction motor 902 of the adjusting base 9. For each rotation of the unloading motor 409, one ball bearing is unloaded into the unloading hopper 406; at the same time, the reduction motor 902 rotates in increments under the command of the control platform 11. For each ball bearing installed, the rotating base 901 rotates one pocket spacing (e.g., 360° / number of pockets), so that all the pockets of the lower retainer sequentially pass through the unloading position until all pockets are filled with one ball bearing.

[0063] Upper Cage Pickup and Visual Alignment: Simultaneously or after ball assembly, the control platform 11 controls the picking mechanism 2 to pick up an upper cage from the upper cage storage cylinder 3 and transfer it to a hovering, ready position above the adjusting base 9. Subsequently, the control platform 11 triggers the first camera 805 and the second camera 907 to simultaneously capture images. The first camera 805 images downwards at the lower cage already fitted with balls, while the second camera 907 images upwards at the suction-loaded upper cage. The vision system within the control platform 11 processes the two images, identifies their respective reference angles, and calculates the angular deviation value (Δθ). Then, the control platform 11 sends a command to the geared motor 902, driving the rotating base 901 along with the lower cage component on it to rotate by an angle of Δθ, thereby completing the precise angular alignment of the upper and lower cages. After alignment, the picking suction cup 206 releases the vacuum, smoothly placing the upper cage onto the aligned lower cage assembly.

[0064] Pressing and Quality Monitoring: After the upper retainer is in place, the control platform 11 immediately controls the pressing cylinder 802 of the pressing mechanism 8 to descend. The pressing plate 803 contacts the workpiece and applies pressure, and the pressure sensor 804 provides real-time feedback of the force value to the control platform 11. The control platform 11 controls the process according to the preset pressure-displacement curve to ensure a smooth pressing process and that the pressure meets the standard, achieving reliable riveting or pressing.

[0065] Finished Product Unloading and Circulation: After pressing is completed, the pressing cylinder 802 resets. The control platform 11 controls the lifting cylinder 905 of the adjusting base 9 to lift the lifting ring 904, thereby removing the finished product from the annular groove 903. Next, the control platform 11 controls the transfer mechanism 10 to push the finished product away from the adjusting base 9 and finally into the collection box 601 in the finished product collection area 6. At this point, a complete assembly cycle ends. The control platform 11 then instructs each mechanism to reset or enter the starting state of the next cycle, realizing continuous automated production.

[0066] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
