Description

Technical Field

[0001] This application relates to the field of bearing assembly technology, and in particular to a bearing unloading mechanism. Background Technology

[0002] Bearing packaging is a key link to ensure the safety of product storage and transportation and prevent surface scratches. Among them, cap packaging has become one of the common forms of small and medium-sized bearings because it can achieve sealed protection and stacked storage. The cap and bearing are usually designed with an interference fit, which requires external force to press them together to achieve tight assembly. At present, the industry generally relies on manual operation to complete the cap pressing. After the operator holds the bearing and aligns it with the cap opening, he presses it together by tapping with his palm or using simple tools. This is not only labor-intensive, but also prone to occupational health risks such as wrist joint strain and palm pressure injury in the long term. In terms of production efficiency, the single person's production capacity for manual pressing is usually less than 5,000 pieces. Moreover, due to the influence of the operator's proficiency, the defect rate of cap tilting and incomplete pressing is as high as 3% to 5%, which is difficult to meet the high efficiency and standardization requirements of large-scale production. [1] Utility Model Content To overcome the problems existing in related technologies, this application provides a bearing unloading mechanism. Through automated feeding design, the bearings of the next-level storage unit are successively fed into the previous-level storage unit under structural constraints, forming a continuous relay conveying.

[0019] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] See Figures 1-3 This application provides a bearing unloading mechanism, including a frame 1, a storage assembly 2, a positioning plate 3, a feeding assembly 4, a first driving component 5, a second driving component 6, and a third driving component 7; The frame 1 has a support platform, and the support platform has a guide channel extending in a preset direction; the storage assembly 2 is disposed on the support platform and includes a plurality of storage units spaced apart along the length of the guide channel. Each storage unit has a vertical receiving cavity for stacking and storing bearings. The discharge end of the storage unit is connected to the guide channel, and the side wall of the storage unit has a mating hole that communicates with the vertical receiving cavity. The first driving component 5 is mounted on the support platform, and its output end is connected to the positioning plate 3. The positioning plate 3 is provided with a plurality of positioning structures that correspond one-to-one with the mating holes. The shape of the positioning structure matches the outer periphery of the bearing. The second driving member 6 is mounted on the frame 1, and its output end is connected to the third driving member 7 to drive the third driving member 7 to slide along the length of the guide channel. The output end of the third driving member 7 is connected to the feeding assembly 4. The feeding assembly 4 is movably mounted in the guide channel and is provided with a plurality of positioning posts. Each positioning post is coaxially mounted with the vertical receiving cavity of the corresponding storage unit. One end of the guide channel forms a transfer station.

[0021] In this embodiment, the storage assembly 2 is composed of several parallel storage units. The stacked bearings are defined from bottom to top as the first bearing, the second bearing, the third bearing, ... the nth bearing; along the transfer station direction, the storage units are defined as the first storage unit, the second storage unit, the third storage unit, ... the nth storage unit. The positioning plate 3 is a long strip-shaped structure. The positioning structure refers to the protrusion extending outward from the surface of the positioning plate 3. The outer peripheral surface of the protrusion is adapted to the outer peripheral surface of the bearing. The feeding assembly 4 is a long strip-shaped structure. The bottom of the feeding assembly 4 is connected to the output end of the third drive member 7. The positioning post is located at the top of the feeding assembly 4. The positioning post and the feeding assembly 4 are integrally formed. Under the drive of the third drive member 7, the positioning post passes through the guide channel and enters the inner hole of the first bearing.

[0022] The discharge process of the bearing unloading mechanism is as follows: (1) The positioning pins of the feeding assembly 4 are aligned directly below each storage unit and rise under the drive of the third driving component 7, passing through and supporting the first bearing at the bottom of the storage unit; at this time, the first driving component 5 drives the positioning plate 3 away from the storage unit, and the positioning structure disengages from the bearing.

[0023] (2) After the feeding assembly 4 descends by one bearing height, the first driving component 5 drives the positioning plate 3 to approach the storage unit, the positioning structure inserts into the mating hole and presses against the second bearing to achieve temporary locking of the upper bearing.

[0024] (3) The second drive component 6 drives the feeding assembly 4 to move to the transfer station, and then the third drive component 7 drives the feeding assembly 4 to rise, so that the first bearing accurately docks with the external robot gripping position; during the rising process, the first bearing of the original second storage unit enters the first storage unit, and due to the continuous pressure of the positioning structure, it is limited to the first storage unit, while the first bearing of the third storage unit enters the second storage unit, and so on.

[0025] (4) The third driving component 7 drives the feeding component 4 to descend and reset, and the second driving component 6 drives the feeding component 4 to move back to the initial position. The positioning column is re-aligned below each storage unit, and steps 1 to 3 are repeated to achieve continuous feeding.

[0026] Correspondingly, to facilitate the replacement of storage units lacking material and to adapt to bearings of different specifications and sizes, the storage units are detachably connected to the frame 1. T-shaped slots (not shown) are machined at intervals along the length of the bearing platform of the frame 1. A wedge-shaped positioning platform is provided at the bottom of the inner sidewall of each slot, and a limit baffle is provided at the end of the slot. The spacing between the slots is consistent with the arrangement spacing of the storage units, and wear-resistant nylon bushings are embedded in the slots. L-shaped stainless steel lugs (not shown) extend symmetrically from both sides of the bottom of the storage unit. The ends of the lugs are provided with inclined locking parts that match the wedge-shaped positioning platforms, and polyurethane buffer pads are installed at the bottom. Simultaneously, guide rounded corners are machined on the outer sides of the lugs to facilitate quick insertion into the slots. Furthermore, positioning holes and positioning pins can also be provided on the side walls of each storage unit. Adjacent storage units achieve secondary positioning through the positioning holes and positioning pins between them, thereby improving the assembly stability of the storage assembly 2.

[0027] Correspondingly, since the bearing is relatively heavy, a friction plate can also be provided at the bottom of the vertical receiving cavity (i.e., the area in contact with the first bearing) to improve the locking ability of the positioning plate 3.

[0028] This application enables the bearings of the next-level storage unit to be successively added to the previous-level storage unit under the structural limiting action through the coordinated operation of locking and releasing of the positioning plate 3 and lifting and translating of the feeding component 4, so as to realize the orderly relay conveying of multiple sets of bearings without the need for manual intervention in grasping and alignment throughout the process.

[0029] Furthermore, the storage unit has a vertical through-hole on its side wall that communicates with the vertical receiving cavity. Operators can directly observe the stacking status of the bearings within the vertical receiving cavity through this through-hole, such as whether the bearings are stuck or neatly arranged. When a bearing encounters obstruction during its descent within the receiving cavity, an auxiliary tool can be inserted through the through-hole to adjust its position, preventing misalignment of the bearings and subsequent feeding failure. In addition, the through-hole reduces the contact area between the storage unit's side wall and the bearing's outer ring, lowering the risk of jamming due to friction during the bearing's descent.

[0030] Furthermore, the surface of the positioning structure facing the vertical receiving cavity is provided with a buffer pad layer. The buffer pad layer can be made of rubber, silicone or polyurethane material. Its function is to absorb the impact energy of the positioning plate 3 when it comes into contact with the bearing and to increase the frictional resistance to the bearing.

[0031] Furthermore, the aforementioned first driving component 5 is a linear cylinder, and a sliding guide assembly is provided between the positioning plate 3 and the support platform. A linear cylinder is a power element that converts compressed air into linear reciprocating motion; specifically, it can be a single-acting or double-acting cylinder. Its output end is rigidly connected to the positioning plate 3 via a piston rod, used to drive the positioning plate 3 to move in a direction perpendicular to the support platform. The sliding guide assembly consists of a guide rail and a slider. The guide rail is fixed to the support platform, and the slider is installed at the bottom of the positioning plate 3. The two cooperate to form a sliding pair, used to constrain the movement trajectory of the positioning plate 3 and prevent deviation or jamming.

[0032] Furthermore, the top of the aforementioned positioning post is provided with a tapered guide portion, the taper of which is 30°~60°. When the feeding assembly 4 moves along the guide channel to below the storage unit, the bearing falls from the vertical receiving cavity to the top of the positioning post. The tapered surface of the tapered guide portion contacts the edge of the bearing's inner hole, and the inclined surface guides the bearing to automatically adjust its position, ensuring that the axis of the bearing's inner hole coincides with the axis of the positioning post. The taper is controlled within the range of 30° to 60°, for example, using a 45° taper angle, which ensures that the bearing slides quickly into the positioning post under gravity, while avoiding bearing jamming or displacement due to excessive tapered surface inclination.

[0033] Furthermore, the bottom of the aforementioned guide channel is provided with several rolling support members. The feeding assembly 4 makes rolling contact with the rolling support members. The rolling support members can be ball bearings, rollers, or drum structures. The rolling contact reduces the frictional resistance when the feeding assembly 4 moves, thereby avoiding jamming caused by sliding friction.

[0034] Furthermore, the aforementioned storage assembly 2 also includes a feeding guide hopper located at the top of the storage unit. The inner diameter of the feeding guide hopper gradually narrows from top to bottom and communicates with the vertical receiving cavity. The guide slope formed by its narrowing inner diameter can guide the bearings axially into the storage unit. Simultaneously, the feeding guide hopper can be connected to an external conveying device or manually added in batches. When operators add bearings in batches, the bearings first fall into the entrance area of ​​the feeding guide hopper and slide along the narrowing inner wall into the vertical receiving cavity of the storage unit under the action of gravity. Because the narrowing structure of the guide hopper creates a spatial constraint on the bearing's falling path, the bearings are automatically corrected to a coaxial state with the vertical receiving cavity before entering the storage unit, eliminating the need for manual adjustment of the bearing's posture. This structure ensures that the stacked bearings remain axially aligned within the storage unit, creating a foundation for the accurate insertion of the positioning pin of the subsequent feeding assembly 4 into the bearing's inner hole.

[0035] Furthermore, a photoelectric sensor is provided on one side of the aforementioned storage component 2. The detection end of the photoelectric sensor faces the transfer station to detect whether the bearing is in place. When the feeding component 4 pushes the bearing to the transfer station along the guide channel, the bearing enters the detection range of the photoelectric sensor. The sensor generates a positioning signal by receiving changes in the light signal that is blocked or reflected. This signal can trigger the control system to stop the feeding action or start the subsequent process.

[0036] Furthermore, both the second driving component 6 and the third driving component 7 are linear cylinders, and the third driving component 7 is slidably connected to the frame 1.

[0037] Furthermore, the bearing feeding mechanism also includes an adjusting component. The second driving component 6 and the third driving component 7 are connected and fixed through the adjusting component. The adjusting component includes a mounting base, an adjusting plate, and an adjusting screw. The adjusting screw is threadedly connected to the mounting base, and one end of the adjusting screw abuts against the adjusting plate. The adjusting plate is bolted to the output shaft of the second driving component 6 and to the mounting base. The third driving component 7 is fixed on the mounting base. When it is necessary to adjust the relative position of the second driving component 6 and the third driving component 7, the bolts between the adjusting plate and the mounting base are loosened, and the adjusting screw is rotated to push the adjusting plate along the surface of the mounting base. At this time, the output shaft of the second driving component 6 moves synchronously with the adjusting plate, while the third driving component 7 remains stationary because it is fixed on the mounting base, thereby changing the initial distance between them. After adjustment, the bolts are tightened again to fix the position of the adjusting plate. This structure allows for precise calibration of the installation position of the driving components before equipment operation or during maintenance, ensuring that the movement trajectory of the feeding assembly 4 in the guide channel remains coaxial with the vertical receiving cavity of the storage unit.

[0038] In some specific embodiments, the adjusting screw can be equipped with a dial to quantify the adjustment amount, for example, one millimeter movement of the adjusting plate for each full rotation. A guide groove can be machined onto the surface of the mounting base, and a raised slider is provided at the bottom of the adjusting plate to embed within the groove, preventing lateral displacement during adjustment.
