A bearing assembly system and method

Abstract

This invention relates to the field of bearing technology, and more specifically, to a bearing assembly system and method. The assembly system includes a base assembly; a turntable unit; and a gripping assembly, which includes a moving unit and a gripping unit. Each gripping unit includes a gripping drive unit, a first gripping module, a second gripping module, a first separating plate, and a second separating plate. A bearing assembly has chamfered edges at both ends of the bearing body. The gripping drive unit drives the first and second gripping modules to move closer together, causing the first and second separating plates to enter the gaps formed by the chamfered edges of adjacent bearing bodies. After the moving unit lifts the gripping unit to a set distance, the gripping drive unit again drives the first and second gripping modules to move closer together, causing the first and second separating plates to fully insert between adjacent bearing bodies until the adjacent bearing bodies separate. This solves the problem of bearing bodies sticking together and being unable to be gripped individually.

Description

Technical Field

[0001] This invention relates to the field of bearing technology, and more specifically, to a bearing assembly system and method. Background Technology

[0002] In automated bearing assembly lines, it is often necessary to separate stacked bearing assemblies and pick them up and transfer them individually. Current mainstream solutions for this function primarily employ suction cups or mechanical grippers. Suction cups utilize negative pressure to directly pick up the topmost bearing; while mechanical grippers typically use a drive to retract the grippers to hold the outer or inner ring of the bearing. These methods are widely used in various automated loading and unloading scenarios to work in conjunction with the gripping mechanism. However, these technologies encounter significant bottlenecks when dealing with bearings that are tightly adhered due to grease adhesion, tight fit, or weak magnetic attraction. Specifically, when a suction cup picks up a target bearing, it easily lifts the bearings below it that are also adhered to it, resulting in the picking up of multiple workpieces at once.

[0003] Existing technologies apply force from outside the bearing housing, failing to effectively intervene and separate the contact surfaces between bearing housings; or, while they may intervene, intervention errors prevent the separation of adhered bearing housings. This increases the mis-grabbing rate during production, requiring additional inspection and correction procedures, reducing production efficiency, and potentially causing errors in subsequent assembly processes, severely impacting the reliability and operational efficiency of the entire automated system. Therefore, there is a need for a device that can intervene at the interface of stacked bearings to reliably separate and grasp individual bearing housings. Summary of the Invention

[0010] The gripping drive unit drives the first gripping module and the second gripping module to move closer to each other, causing the first separating piece and the second separating piece to enter the gap formed by the chamfer of the adjacent bearing body; after the moving unit drives the gripping unit to lift to the set distance, the gripping drive unit drives the first gripping module and the second gripping module to move closer to each other again, causing the first separating piece and the second separating piece to be fully inserted between the adjacent bearing bodies until the adjacent bearing bodies separate.

[0012] In some embodiments, the moving unit includes a translation section; the translation section includes a guide rail and a slider; one end of the guide rail away from the turntable body is connected to the mounting bracket; the slider is sleeved on the guide rail; the slider is slidably connected to the guide rail.

[0013] In some embodiments, the moving unit further includes a vertical displacement section; the vertical displacement section includes a connecting block and a telescopic rod, the upper end of the connecting block is connected to the slider; the lower end of the connecting block is connected to the telescopic rod; and the bottom of the telescopic rod is connected to the gripping unit.

[0015] In some embodiments, the thickness of both the first and second separation plates is less than the maximum distance between the gaps formed by the chamfered portions of adjacent bearing bodies.

[0016] In some embodiments, the lifting plate is inclined relative to the horizontal plane and mounted on the positioning rod; the first separating plate and the second separating plate are not at the same horizontal plane, and the tilt angle formed by the first separating plate and the second separating plate is the same as the tilt angle of the lifting plate; used to grip the inclined bearing body.

[0017] In some embodiments, the first gripping module includes a first support portion and a first clamping portion; the upper end of the first support portion is drivenly connected to the gripping drive portion; the lower end of the first support portion is connected to the first clamping portion; and the lower end of the first clamping portion is connected to the first separating piece.

[0023] The gripping drive unit drives the first gripping module and the second gripping module to move closer to each other, causing the first separating plate and the second separating plate to move horizontally relative to each other and insert into the gap formed by the chamfered part of the two adjacent bearing bodies at the top.

[0024] The moving unit drives the gripping unit to lift vertically upward to the set distance, causing the first bearing body at the top to rise, thereby initially separating it from the bearing body below and widening the gap;

[0025] The gripping drive unit drives the first gripping module and the second gripping module to move closer to each other, causing the first separating piece and the second separating piece to be fully inserted between the adjacent bearing bodies until the first bearing body is completely separated from the bearing body below.

[0026] The moving unit drives the gripping unit to move the separated first bearing body to the next work station.

[0027] To solve the problem of bearing bodies sticking and being unable to be gripped individually, this invention has the following advantages:

[0028] By setting a first separation plate and a second separation plate, inserting them into the gap formed by the chamfered part of the adjacent bearing body, and then lifting them upwards, a certain gap is maintained when separating the bearing body below. This application utilizes the gap formed by the chamfered part structure of the bearing body itself, and through the compound action of "initial insertion-lifting-re-insertion separation", it can effectively break the adhesion between bearings, reliably separate and grasp individual bearing bodies, and has a high grasping success rate.

[0038] In the field of automated bearing assembly, it is necessary to install sealing end caps on both ends of the bearing body 61 that has been lubricated with oil. This often requires separating multiple stacked bearing bodies 61 and picking them up one by one. However, the stacked bearing bodies 61 tend to stick together due to the grease, and existing technology cannot reliably intervene to separate the contact interface between the bearing bodies 61. Even when attempts are made, separation fails due to methodological errors (such as improper insertion position). This results in a series of problems, including a high rate of mis-picking, decreased production efficiency, and disruption of subsequent processes.

[0039] Example 1:

[0040] In this embodiment, as Figure 1 and 2 As shown, a bearing assembly system includes:

[0041] A base assembly 50, the base assembly 50 including a platform 51 and a mounting bracket 52; the mounting bracket 52 is connected to the platform 51.

[0042] The turntable unit 11 includes a turntable body 111, a positioning rod 112, and a turntable drive unit 113. The turntable body 111 is disposed on the top of the platform 51. The positioning rod 112 is disposed on the turntable body 111. The turntable drive unit 113 is disposed on the bottom of the platform 51 of the base assembly 50. The turntable drive unit 113 is drivenly connected to the turntable body 111.

[0043] The bearing assembly 60 is placed in the positioning rod 112. Multiple sets of positioning rods 112 can be set. When the bearing assembly 60 in one set of positioning rods 112 has been gripped, the turntable drive unit 113 drives the turntable body 111 to rotate, rotating the bearing assemblies 60 to be gripped in other positioning rods 112 to the gripping position to wait for the gripping operation.

[0044] A gripping component 20 includes a moving unit 21 and a gripping unit 22; the gripping unit 22 is connected to the moving unit 21; the moving unit 21 is connected to the mounting bracket 52; the gripping unit 22 includes a gripping drive unit 221, a first gripping module 222, a second gripping module 224, a first separation piece 223, and a second separation piece 225; the gripping drive unit 221 is drivenly connected to the first gripping module 222 and the second gripping module 224 respectively; the first separation piece 223 is disposed at the bottom of the first gripping module 222; the second separation piece 225 is disposed at the bottom of the second gripping module 224.

[0045] The gripping drive unit 221 controls the first gripping module 222 and the second gripping module 224, as well as the first separation plate 223 and the second separation plate 225 respectively installed at the bottom of the first gripping module 222 and the second gripping module 224. The gripping drive unit 221 drives the first separation plate 223 and the second separation plate 225 to approach each other and accurately enter the gap formed by the chamfered part 62 of the adjacent bearing body 61.

[0046] The bearing assembly 60 includes a bearing body 61; a plurality of bearing bodies 61 are stacked in the positioning rod 112, and the two ends of the bearing body 61 are provided with chamfered portions 62;

[0047] like Figure 4 As shown, since the bearing body 61 has chamfered edges 62 at both ends, gaps of a certain spacing are naturally formed at the edges when stacked.

[0048] The gripping drive unit 221 drives the first gripping module 222 and the second gripping module 224 to move closer to each other, causing the first separating piece 223 and the second separating piece 225 to enter the gap formed by the chamfered part 62 of the adjacent bearing body 61; after the moving unit 21 drives the gripping unit 22 to be raised to the set distance, the gripping drive unit 221 drives the first gripping module 222 and the second gripping module 224 to move closer to each other again, causing the first separating piece 223 and the second separating piece 225 to be fully inserted between the adjacent bearing bodies 61 until the adjacent bearing bodies 61 separate.

[0049] The first separating piece 223 and the second separating piece 225 enter the gap formed by the chamfered portion 62 of the adjacent bearing body 61. The vertical moving part 212 drives the gripping unit 22 to lift upward by a predetermined distance. If the two adjacent bearing bodies 61 are stuck together, with the first one above and the second one below, this lifting action can create a slight separation tendency between the first bearing body 61 (which is initially stuck by the separating piece) and the second bearing body 61, or increase the gap below them. At the same time, it creates and preserves the necessary operating space for the next step of the separating piece to penetrate deeper, avoiding jamming or damage to the second bearing body 61 that may be located below due to lack of room to maneuver if it is directly and forcibly inserted completely. After obtaining the required operating space, the gripping drive part 221 drives the first separating piece 223 and the second separating piece 225 to move closer to each other, pushing both separating pieces to be fully inserted between the initially separated adjacent bearing bodies 61.

[0050] Ultimately, through the aforementioned combined action process of "horizontal intervention → vertical lifting separation space → horizontal deep thorough separation", the system can efficiently and reliably separate the adhered bearing body 61, ensuring that only a single bearing body 61 is grasped each time, greatly improving the grasping success rate and system reliability.

[0051] Furthermore, such as Figure 2 As shown, the device includes a lifting unit 12, which includes a lifting plate 121 and a lifting drive unit 122. The lifting plate 121 is inserted into the positioning rod 112. The lifting plate 121 is slidably connected to the positioning rod 112. The bearing body 61 is stacked on the lifting plate 121. The lifting drive unit 122 is connected to the lifting plate 121. The lifting drive unit 122 drives the lifting plate 121 to rise and fall.

[0052] The turntable unit 11 and the lifting unit 12 together form the turntable assembly 10. The turntable body 111 is provided with a lifting hole, which is used for the lifting drive unit 122 to pass through the turntable body 111 to push the lifting plate 121 upward; the lifting plate 121 is provided with a limiting hole, which is used for the positioning rod 112 to pass through, and the limiting hole makes the lifting plate 121 only able to move vertically and not horizontally.

[0053] The lifting plate 121 is slidably connected to the positioning rod 112, allowing the lifting plate 121 to slide smoothly in the vertical direction. The lifting rod 121 is located at the bottom of the bearing assembly 60, providing upward thrust to the bearing assembly 60. The bearing body 61 is directly stacked on the lifting plate 121, and the horizontal displacement of the bearing assembly 60 is limited by the positioning rod 112. The lifting drive unit 122 can precisely control its lifting and lowering displacement. The lifting drive unit 122 drives the lifting plate 121 to rise until the upper surface of the topmost bearing body 61 reaches a preset, fixed gripping height. This height is the optimal position for the gripping unit 22 to perform separation and gripping actions. The vertical movement part 212 of the gripping assembly 20 has a fixed descent stroke each time, and its endpoint is precisely to ensure that the separating piece can be accurately aligned with the gap of the bearing body 61 at the gripping height. After completing one gripping operation, the vertical movement part 212 rises to the fixed origin. Once a bearing body 61 is successfully removed, the lifting drive unit 122 immediately drives the lifting plate 121 to rise a precise distance equal to the thickness of one bearing body 61. This compensating action causes the top layer of the remaining bearing body 61 stack to precisely return to the gripping height. The turntable unit 11 rotates, switching the next compensated lifting position to the gripping position, and the gripping unit 22 resumes operation with a fixed descent stroke, thus completing the cycle.

[0054] Therefore, through real-time compensation by the lifting unit 12, it is ensured that the topmost bearing to be grabbed is always at the same height, regardless of how many bearings remain in the material pile. This eliminates the need for the vertical movement part 212 of the grabbing unit 22 to be equipped with a complex visual positioning or displacement sensing system; it only needs to execute a fixed descent stroke, greatly simplifying the control logic, ensuring the consistency of each grabbing action, and avoiding the complex problem of needing to dynamically adjust the grabbing posture due to continuous changes in grabbing height. This fundamentally eliminates the risk of insertion failure, collision, or scratching of the bearings due to height deviation.

[0055] Furthermore, such as Figure 2 As shown, the moving unit 21 includes a translation part 211; the translation part 211 includes a guide rail 2111 and a slider 2112; one end of the guide rail 2111 away from the turntable body 111 is connected to the mounting bracket 52; the slider 2112 is sleeved on the guide rail 2111; the slider 2112 is slidably connected to the guide rail 2111.

[0056] The horizontal movement of the gripping component 20 is achieved through a sliding structure of guide rail 2111 and slider 2112. This allows the gripping unit 22 to move very precisely above different workstations on the turntable, ensuring that the endpoint position is consistently high each time. Compared to other linear motion methods, the guide rail 2111 and slider 2112 mechanism provides strong lateral support and torque bearing capacity, exhibiting high rigidity. This ensures that the gripping unit 22 can accurately and stably reach the predetermined workstation time and time again, creating the prerequisites for subsequent precise separation and gripping actions.

[0057] Furthermore, such as Figure 1 As shown, the moving unit 21 further includes a vertical moving part 212; the vertical moving part 212 includes a connecting block 2121 and a telescopic rod 2122, the upper end of the connecting block 2121 is connected to the slider 2112; the lower end of the connecting block 2121 is connected to the telescopic rod 2122; and the bottom of the telescopic rod 2122 is connected to the gripping unit 22.

[0058] The vertical movement unit 212 moves vertically via the telescopic rod 2122, ensuring an absolutely straight and highly vertical lifting path. This is crucial for the separation plate to be precisely and vertically inserted into narrow bearing gaps without oblique collisions. It significantly reduces vibration and jitter during movement, improving the rigidity and stability of the entire system. When the gripping unit 22 performs rapid lifting or insertion / separation actions, it effectively resists impacts and interference, ensuring reliable execution of the movements.

[0059] Furthermore, such as Figure 1 As shown, it also includes a separating component 40; the separating component 40 includes a separating beam 41 and a receiving box 42; the separating beam 41 is disposed on the mounting frame 52; the receiving box 42 is disposed on the side of the mounting frame 52; the receiving box 42 is disposed on the side near the turntable body 111; the separating beam 41 is used to block excess bearing bodies 61 that are stuck to the bottom of the removed bearing body 61; the receiving box 42 is used to collect the excess bearing bodies 61 that are blocked down.

[0060] The thickness of the partition beam 41 needs to be designed according to the specifications of the bearing to ensure that only one bearing body 61 can be located on the partition beam 41 at a time and pass through the partition beam 41 to enter the next process. All excess bearing bodies 61 that are stuck to the bottom are blocked by the partition beam 41 and fall into the receiving box 42. The receiving box 42 is installed on the side of the mounting frame 52 and is lower than the height of the partition beam 41 to ensure that excess bearing bodies 61 that are blocked can be collected by the receiving box 42.

[0061] Although the core gripping unit 22 can effectively separate most adhesive situations through a "two-step" separation method, there is still a risk that extreme grease adhesion or vacuum adsorption may accidentally lift multiple bearings. The separator beam 41, as a passive, mechanical physical barrier, is set on the gripping path and can reliably intercept and scrape away any excess bearings 61 that have not been successfully separated below the gripped bearing body 61. This ensures that the output from the system is always and only a single bearing body 61, fundamentally eliminating the risk of accidental gripping flowing into subsequent precision assembly processes and further improving the system's reliability.

[0062] The design of the receiving box 42 collects the excess bearing bodies 61 in a centralized and orderly manner, preventing them from falling randomly into the equipment or on the production line, which could cause equipment jamming, interfere with the operation of other workstations, or cause workpiece contamination and damage.

[0063] The separator assembly 40 solves the potential problems without any sensors, actuators, or complex control systems, using only a fixedly mounted separator beam 41 and a receiving box 42. This purely mechanical solution is extremely simple in structure, low in manufacturing cost, eliminates the risk of circuit or precision component failure, is highly reliable, and requires very little routine maintenance.

[0064] Furthermore, the thickness of the first separation piece 223 and the second separation piece 225 is less than the maximum distance of the gap formed by the chamfered portion 62 of the adjacent bearing body 61.

[0065] Ensuring that the separating plates can smoothly and without interference insert into the gap is a prerequisite for achieving the separation function. When the bearing bodies 61 are naturally stacked, a tiny, inherent gap is formed between their chamfered portions 62. The thickness of both the first separating plate 223 and the second separating plate 225 is smaller than the distance of this natural gap. This allows the separating plates to easily and smoothly enter this narrow space under the push of the gripping drive unit 221, without forcibly squeezing or colliding with the edges of the upper and lower bearing bodies 61. This is the physical basis for the initiation and execution of the entire separation action.

[0066] If the thickness of the first separating plate 223 and the second separating plate 225 is greater than or equal to the maximum distance of the gap, forced insertion will inevitably cause the separating plates to scrape, squeeze or pry the chamfer or even the raceway surface of the bearing, thereby scratching or damaging the outer surface of the precision-machined bearing body 61, affecting its accuracy and performance.

[0067] Furthermore, the lifting plate 121 is inclined relative to the horizontal plane and mounted on the positioning rod 112; the first separating plate 223 and the second separating plate 225 are not at the same horizontal plane, and the tilt angle formed by the first separating plate 223 and the second separating plate 225 is the same as the tilt angle of the lifting plate 121; used to grasp the inclined bearing body 61.

[0068] This solution overcomes the limitations of traditional horizontally stacked workpieces by matching the inclined setting of the lifting plate 121 with the non-coplanar design of the first separating plate 223 and the second separating plate 225. The logic, process, and effect of its separation action are completely consistent with those when handling horizontal workpieces. The advantage of using the inclined setting is that it increases the clearance space between the bearing body 61 and the positioning rod 112, preventing the bearing body 61 from colliding or getting stuck with the positioning rod 112 during the transfer process. This would not only prevent successful gripping but also potentially severely scratch the bearing surface.

[0069] Furthermore, such as Figure 3 As shown, the first gripping module 222 includes a first support portion 2221 and a first clamping portion 2222; the upper end of the first support portion 2221 is drivenly connected to the gripping drive portion 221; the lower end of the first support portion 2221 is connected to the first clamping portion 2222; and the lower end of the first clamping portion 2222 is connected to the first separating piece 223.

[0070] The modular structure, consisting of the first support part 2221 and the first clamping part 2222, primarily focuses on the precise installation and fixation of the first separating piece 223. Its design emphasizes ensuring the accuracy and relative position of the mounting location. This modular design means that when handling bearings of different sizes or types, only the first clamping part 2222, designed for the specific bearing, needs to be replaced. This results in rapid product changeover, low cost, and significantly enhanced equipment flexibility and versatility. Furthermore, if the first clamping part 2222 or the first separating piece 223 wears down after prolonged use, it can be quickly and easily replaced individually, significantly reducing maintenance costs and downtime.

[0071] Furthermore, such as Figure 3 As shown, the second gripping module 224 includes a second support portion 2241 and a second clamping portion 2242; the upper end of the second support portion 2241 is drivenly connected to the gripping drive portion 221; the lower end of the second support portion 2241 is connected to the second clamping portion 2242; and the lower end of the second clamping portion 2242 is connected to the second separating piece 225.

[0072] The gripping unit 22 includes a gripping base, and a first gripping module 222 and a second gripping module 224 are installed at the bottom of the gripping base.

[0073] Example 2:

[0074] In this embodiment, the present application also provides a bearing assembly method, including the following steps:

[0075] S10: Provide and initialize the bearing assembly 60 gripping system, stacking multiple bearing bodies 61 in the positioning rod 112 of the turntable unit 11;

[0076] S20: The turntable drive unit 113 drives the turntable body 111 to rotate, moving the workstation carrying the bearing body 61 to the gripping workstation.

[0077] S30: The moving unit 21 drives the gripping unit 22 to move, so that the first separating piece 223 and the second separating piece 225 are positioned directly above the stack of bearing bodies 61 at the gripping station;

[0078] S40: The gripping drive unit 221 drives the first gripping module 222 and the second gripping module 224 to move closer to each other, causing the first separating piece 223 and the second separating piece 225 to move horizontally relative to each other and insert into the gap formed by the chamfered part 62 of the two adjacent bearing bodies 61 at the top.

[0079] S50: The moving unit 21 drives the gripping unit 22 to lift vertically upward to the set distance, so that the first bearing body 61 at the top rises, thereby initially separating from the bearing body 61 below and widening the gap.

[0080] S60: The gripping drive unit 221 drives the first gripping module 222 and the second gripping module 224 to move closer to each other, causing the first separating piece 223 and the second separating piece 225 to be fully inserted between the adjacent bearing bodies 61 until the first bearing body 61 is completely separated from the lower bearing body 61.

[0081] S70: The moving unit 21 drives the gripping unit 22 to move the separated first bearing body 61 to the next work station.

[0082] In other embodiments, the separated bearing body 61 enters the next station for assembly. The successfully gripped bearing body 61 is transported to the assembly station by the conveying assembly 30, which includes a conveyor belt 31, a conveying drive unit 32, and support rollers 33.
