Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearings, in particular to a bearing assembly assembling system and method. BACKGROUND

[0002] In the automatic assembly production line of bearings, it is often necessary to separate the stacked bearing assemblies and transport them one by one. The mainstream scheme in the prior art to achieve this function is to use a suction cup or a mechanical claw to grip. For the suction cup method, it directly sucks the top single bearing by using negative pressure; and for the mechanical claw method, it usually drives the clamping jaw to close to clamp the outer ring or inner ring of the bearing. These methods are commonly used in various automatic feeding and discharging scenes to complete the work with the gripping mechanism. However, the above-mentioned technology encounters a significant bottleneck problem when dealing with bearings that are tightly attached due to the adhesion of lubricating grease, tight fit or weak magnetic adsorption. Specifically, when the suction cup sucks the target bearing body, it is easy to bring the bearing body below it together, resulting in the suction of multiple workpieces at a time.

[0003] The prior art all applies force from the outside of the bearing body, and cannot effectively intervene and separate the contact surfaces between the bearing bodies; or intervene in the contact surfaces between the bearing bodies, but due to the intervention deviation, it cannot separate the adhered bearing bodies. This will increase the mis-grabbing rate in the production process, not only requiring additional detection and correction procedures, but also reducing production efficiency, and more likely to cause confusion in the subsequent assembly process, seriously affecting the reliability and operating efficiency of the entire automation system. Therefore, the prior art needs a device that can intervene from the interface of the bearing stack, so as to reliably separate and grab a single bearing body. SUMMARY

[0024] The moving unit drives the grabbing unit to vertically move upward to a set distance, so that the first bearing body at the top is lifted, thereby preliminarily separating from the bearing body below and expanding the gap;

[0025] The grabbing driving part drives the first grabbing module and the second grabbing module to move close to each other again, drives the first separating piece and the second separating piece to completely insert between the adjacent bearing bodies, until the first bearing body is completely separated from the bearing body below;

[0038] In the field of bearing automatic assembly, it is necessary to install sealing end covers on both ends of bearing bodies 61 with lubricating oil. It is often necessary to separate and individually grasp a plurality of stacked bearing bodies 61. However, the stacked bearing bodies 61 can be adhered together by oil, and the prior art cannot reliably intervene and separate the contact interfaces between the bearing bodies 61, or although attempts are made to intervene, separation fails due to method deviation (such as improper insertion position). This causes a series of problems such as high mis-grasping rate, reduced production efficiency, and subsequent process disorder.

[0039] Embodiment One:

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

[0041] A base assembly 50, the base assembly 50 includes a table top 51 and a mounting frame 52; the mounting frame 52 is connected with the table top 51;

[0042] A turntable unit 11, the turntable unit 11 includes a turntable body 111, a positioning rod 112 and a turntable driving part 113; the turntable body 111 is arranged on the top of the table top 51; the positioning rod 112 is arranged on the turntable body 111; the turntable driving part 113 is arranged on the bottom of the table top 51 of the base assembly 50; the turntable driving part 113 is drivingly connected with the turntable body 111;

[0043] The bearing assembly 60 is placed in the positioning rod 112, and the positioning rod 112 can be provided in multiple groups. When the bearing assembly 60 in one of the positioning rods 112 is grabbed, the turntable driving part 113 drives the turntable body 111 to rotate, so that the bearing assembly 60 to be grabbed in other positioning rods 112 is rotated to a position to be grabbed and waits for grabbing operation.

[0044] A grabbing assembly 20, the grabbing assembly 20 includes a moving unit 21 and a grabbing unit 22; the grabbing unit 22 is connected with the moving unit 21; the moving unit 21 is connected with the mounting frame 52; the grabbing unit 22 includes a grabbing driving part 221, a first grabbing module 222, a second grabbing module 224, a first separating piece 223 and a second separating piece 225; the grabbing driving part 221 is drivingly connected with the first grabbing module 222 and the second grabbing module 224 respectively; the first separating piece 223 is arranged on the bottom of the first grabbing module 222; the second separating piece 225 is arranged on the bottom of the second grabbing module 224;

[0045] The first grabbing module 222 and the second grabbing module 224 controlled by the grabbing driving part 221, and the first separating piece 223 and the second separating piece 225 respectively arranged on the bottom of the first grabbing module 222 and the second grabbing module 224, are driven by the grabbing driving part 221 to drive the first separating piece 223 and the second separating piece 225 to approach each other, and accurately enter the gap formed by the chamfered portion 62 of the adjacent bearing body 61.

[0046] A bearing assembly 60, the bearing assembly 60 includes a bearing body 61; a plurality of bearing bodies 61 are stacked in the positioning rod 112, and chamfered portions 62 are arranged at the edges of both ends of the bearing body 61;

[0047] As shown in Figure 4 Because the chamfered portions 62 are arranged at the edges of both ends of the bearing body 61, the edges naturally form a gap with a certain spacing when stacked.

[0048] The grabbing driving part 221 drives the first grabbing module 222 and the second grabbing module 224 to move close to each other, and drives the first separating piece 223 and the second separating piece 225 to enter the gap formed by the chamfered portion 62 of the adjacent bearing body 61; after the moving unit 21 drives the grabbing unit 22 to be lifted to a set distance, the grabbing driving part 221 drives the first grabbing module 222 and the second grabbing module 224 to move close to each other again, and drives the first separating piece 223 and the second separating piece 225 to be inserted between the adjacent bearing bodies 61 until the adjacent bearing bodies 61 are separated.

[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 lifting part 212 drives the grabbing unit 22 to be lifted upward by a set distance. If the adjacent two bearing bodies 61 are adhered together, the first bearing body 61 located on the upper side and the second bearing body 61 located on the lower side are adhered together. The lifting action can make the first bearing body 61 (preliminarily clamped by the separating piece) and the second bearing body 61 have a slight separation trend or increase the gap below, and at the same time, create and reserve the necessary operation space for the next deep action of the separating piece, so as to avoid the situation that the second bearing body 61 located below is directly forced to be completely inserted and is clamped or damaged due to no retreat space. After the required operation space is obtained, the grabbing driving part 221 drives the first separating piece 223 and the second separating piece 225 to move close to each other again, and drives the two separating pieces to be inserted between the adjacent bearing bodies 61 which have been preliminarily separated.

[0050] Finally, through the composite action process of “horizontal intervention → vertical lifting separation space → horizontal deepening complete separation”, the system can efficiently and reliably separate the adhered bearing bodies 61, and finally ensure that only a single bearing body 61 is grabbed each time, so that the grabbing success rate and system reliability are greatly improved.

[0051] Further, as shown in Figure 2 The jacking unit 12 comprises a jacking plate 121 and a jacking driving part 122; the jacking plate 121 is inserted into the positioning rod 112; the jacking plate 121 is in sliding connection with the positioning rod 112; the bearing bodies 61 are stacked on the jacking plate 121; the jacking driving part 122 is connected with the jacking plate 121; and the jacking driving part 122 drives the jacking plate 121 to ascend and descend.

[0052] The rotating disc unit 11 and the jacking unit 12 form a rotating disc assembly 10. The jacking hole is arranged on the rotating disc body 111, and is used for the jacking driving part 122 to push the jacking plate 121 upward through the rotating disc body 111; the limiting hole is arranged on the jacking plate 121, and is used for passing through the positioning rod 112. The limiting hole makes the jacking plate 121 only move vertically and cannot move horizontally.

[0053] The jacking plate 121 is in sliding connection with the positioning rod 112, and the jacking plate 121 can slide smoothly in the vertical direction. The jacking plate 121 is arranged at the bottom of the bearing assembly 60, and is used to provide upward thrust to the bearing assembly 60. The bearing body 61 is directly stacked on the jacking plate 121, and the displacement of the bearing assembly 60 in the horizontal direction is limited by the positioning rod 112. The jacking driving part 122 can accurately control the lifting displacement. The jacking driving part 122 drives the jacking plate 121 to rise until the upper surface of the bearing body 61 at the top layer reaches a pre-set fixed grabbing height. This height is the best position for the separation and grabbing action of the grabbing unit 22. The vertical displacement part 212 of the grabbing assembly 20 has a fixed descending stroke, and the end position thereof is just to ensure that the separation sheet can be accurately aligned with the gap of the bearing body 61 at the grabbing height. After completing a grabbing, the vertical displacement part 212 rises to the fixed original position. After a bearing body 61 is successfully taken away, the jacking driving part 122 immediately drives the jacking plate 121 to rise by an accurate distance of the thickness of the bearing body 61. This compensation action makes the top layer of the remaining bearing body 61 stack accurately rise to the grabbing height again. The rotating disc unit 11 rotates to switch the next jacking work station that has been compensated to the grabbing position, and the grabbing unit 22 again performs the work with the fixed descending stroke, so as to realize the cycle.

[0054] Therefore, through the real-time compensation of the jacking unit 12, it is ensured that the bearing to be grabbed at the top layer of the stack is always at the same height regardless of the number of bearings in the stack. This makes the vertical displacement part 212 of the grabbing unit 22 not need to be equipped with a complex visual positioning or displacement sensing system, and only needs to perform a fixed descending stroke, greatly simplifies the control logic, ensures the consistency of each grabbing action, avoids the complex problem of dynamically adjusting the grabbing pose due to the change of the grabbing height, and fundamentally eliminates the risk of insertion failure, collision or scratching of the bearing due to height deviation.

[0055] Further, as shown in Figure 2 The moving unit 21 comprises a translation part 211. The translation part 211 comprises a guide rail 2111 and a sliding block 2112. One end of the guide rail 2111 away from the rotating disc body 111 is connected with the mounting frame 52. The sliding block 2112 is sleeved on the guide rail 2111. The sliding block 2112 is in sliding connection with the guide rail 2111.

[0056] The sliding structure of guide rail 2111 and sliding block 2112 is used to realize the horizontal movement of grabbing assembly 20, which enables grabbing unit 22 to move very accurately above different stations on the turntable and ensures that the end position of each movement is consistent in height. Compared with other linear motion methods, the guide rail 2111 sliding block 2112 mechanism can provide strong lateral support force and torque carrying capacity, and is rigid; it ensures that grabbing unit 22 can accurately and stably reach the predetermined station time after time, creating a prerequisite for subsequent precise separation and grabbing actions.

[0057] Further, as shown in Figure 1 The moving unit 21 further comprises a vertical moving part 212; the vertical moving part 212 comprises a connecting block 2121 and a telescopic rod 2122, the upper end of the connecting block 2121 is connected with the sliding block 2112; the lower end of the connecting block 2121 is connected with the telescopic rod 2122; the bottom of the telescopic rod 2122 is connected with the grabbing unit 22.

[0058] The vertical moving part 212 moves vertically through the telescopic rod 2122, ensuring that the lifting path is absolutely straight and has very high verticality, which is crucial for ensuring that the separated piece is accurately and vertically inserted into the narrow bearing gap rather than colliding obliquely; it greatly reduces vibration and shaking during movement, improving the rigidity and stability of the entire system. When the grabbing unit 22 performs rapid lifting action or insertion separation, it can effectively resist impact and interference, ensuring reliable execution of the action.

[0059] Further, as shown in Figure 1 It further comprises a separation assembly 40; the separation assembly 40 comprises a separation beam 41 and a receiving box 42; the separation beam 41 is arranged on the mounting frame 52; the receiving box 42 is arranged on the side of the mounting frame 52; the receiving box 42 is arranged on the side close to the turntable body 111; the separation beam 41 is used to block the excess bearing body 61 adhered to the bottom of the taken bearing body 61; the receiving box 42 is used to collect the excess bearing body 61 blocked down.

[0060] The thickness of the separation beam 41 needs to be designed according to the specifications of the bearing, ensuring that only one bearing body 61 is located above the separation beam 41 each time, and the excess bearing body 61 adhered to the bottom is all blocked by the separation beam 41 into the receiving box 42; the receiving box 42 is installed on the side of the mounting frame 52, and its height is lower than that of the separation beam 41, ensuring that the excess bearing body 61 blocked can be collected by the receiving box 42.

[0061] Although the core gripping unit 22 can effectively separate most sticking cases by the "two-step" separation method, there is still a risk of extreme grease sticking or vacuum suction causing unexpected multiple bearings to be brought up. The partition beam 41, as a passive, mechanical physical barrier, is set on the gripping path and can absolutely reliably intercept and scrape off any extra bearing bodies 61 under the gripped bearing body 61 that have not been successfully separated; it ensures that only a single bearing body 61 is output from the system and fundamentally eliminates the risk of misgripping flowing into the subsequent precision assembly process, further improving system reliability.

[0062] The design of the receiving box 42 concentrates and orderly collects the intercepted extra bearing bodies 61, avoiding their random falling into the device interior or production line, which may cause device jamming, interfere with the operation of other stations, or cause workpiece contamination and damage.

[0063] The partition assembly 40 does not require any sensors, drivers, or complex control systems, but solves the potential problem only by a fixedly installed partition beam 41 and a receiving box 42. This purely mechanical solution has an extremely simple structure, low manufacturing cost, no risk of circuit or precision element failure, high reliability, and extremely low daily maintenance requirement.

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

[0065] Ensuring that the separation piece can be smoothly inserted into the gap without interference is a prerequisite for realizing the separation function. When the bearing bodies 61 are naturally stacked, a small, inherent gap will be formed between the chamfered portions 62. The thickness of the first separation piece 223 and the second separation piece 225 is less than the spacing of this natural gap. This allows the separation piece to easily and smoothly enter this narrow space under the push of the gripping drive portion 221, without forcibly extruding or colliding with the upper and lower bearing body 61 edges. This is the physical basis for the entire separation action to be started and executed.

[0066] If the thickness of the first separation piece 223 and the second separation piece 225 is greater than or equal to the maximum distance of the gap spacing, forcibly inserting will inevitably cause the separation piece to scratch, extrude, or pry the chamfered portion or raceway surface of the bearing, thereby scratching or bruising the precisely machined outer surface of the bearing body 61, affecting its precision and performance.

[0067] Further, the jacking plate 121 is arranged on the positioning rod 112 in an inclined manner relative to the horizontal plane; the first separating piece 223 and the second separating piece 225 are not in the same horizontal plane, and the inclination angle formed by the first separating piece 223 and the second separating piece 225 is the same as the inclination angle of the jacking plate 121; and the bearing body 61 is arranged in an inclined manner.

[0068] The scheme breaks through the limitation of the traditional horizontally stacked workpieces by matching the inclination of the jacking plate 121 with the non-coplanar design of the first separating piece 223 and the second separating piece 225, and the logic, process and effect of the separating action are completely consistent with those when handling horizontal workpieces. The inclined arrangement has the advantage of increasing the gap space between the bearing body 61 and the positioning rod 112, preventing the bearing body 61 from colliding with or being stuck to the positioning rod 112 during the transfer process, so that the bearing surface cannot be successfully grabbed and may be seriously scratched.

[0069] Further, as shown in the first embodiment of the present application, Figure 3 the first grabbing module 222 comprises a first supporting part 2221 and a first clamping part 2222; the upper end of the first supporting part 2221 is drivingly connected with the grabbing driving part 221; the lower end of the first supporting part 2221 is connected with the first clamping part 2222; and the lower end of the first clamping part 2222 is connected with the first separating piece 223.

[0070] The first supporting part 2221 and the first clamping part 2222 constitute a split modular structure, and the first clamping part 2222 is mainly responsible for accurately installing and fixing the first separating piece 223, and the design focuses on ensuring the accuracy and relative position of the installation position. The modular design means that when different sizes or types of bearings need to be handled, only the first clamping part 2222 designed for a specific bearing needs to be replaced. This makes the product changeover fast and low in cost, greatly enhancing the flexibility and versatility of the equipment. At the same time, if the first clamping part 2222 or the first separating piece 223 is worn after long-term use, it can also be quickly and conveniently replaced individually, significantly reducing maintenance costs and downtime.

[0071] Further, as shown in the first embodiment of the present application, Figure 3 the second grabbing module 224 comprises a second supporting part 2241 and a second clamping part 2242; the upper end of the second supporting part 2241 is drivingly connected with the grabbing driving part 221; the lower end of the second supporting part 2241 is connected with the second clamping part 2242; and the lower end of the second clamping part 2242 is connected with the second separating piece 225.

[0072] The grabbing unit 22 comprises a grabbing seat, and the first grabbing module 222 and the second grabbing module 224 are installed at the bottom of the grabbing seat.

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

[0076] S20: the turntable driving part 113 drives the rotation of the turntable body 111, and moves the work station carrying the bearing body 61 to the grabbing work station;
