[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] like Figure 1-11 As shown, an embodiment of the present invention provides an automated assembly device for forklift steering knuckle bearing inner rings, comprising a control system, a support body 2, a flow tray 1, a lifting plate 3, a hopper 4, a material gripping mechanism 11, and a drive mechanism 12. The control system can be a PLC control system or other structure such as a chip or controller to control the entire device's operation, such as the start and stop of the related power structure 16, the movement process and travel range of the drive structure, etc.

[0040] See also Figure 2-11In one embodiment of the present invention, the support body 2 may include a number of fixedly connected plate-shaped and rod-shaped structures to form a support structure of the equipment, forming an installation position for installing various functional components. The support body 2 is arranged on the path of the conveyor line 7, and is connected with the previous and next processes through the conveyor line 7 to realize the automated processing of the entire production process. The conveyor line 7 is used to transport the produced workpieces and improve the overall automation level. The conveyor line 7 may include two parallel and spaced brackets, and a wheel structure or a chain structure is provided at the top of the bracket to provide power to drive the product or flow tray 1 on the conveyor line 7 to move. The conveyor line 7 may also adopt other conveying structures that can realize the conveying function. The outer side of the support body 2 (especially the moving structure part) may be provided with a fence 5, which plays a shielding role and reduces safety hazards. Fence 5 has an operational gap for accessing and unloading materials or for maintenance. A safety light barrier 6 can be installed at the gap. When the safety light barrier 6 detects the presence of an entity within the operational gap, such as an operator reaching into the space enclosed by fence 5, the operation of silo 4 stops, meaning that silo 4 must remain stationary. The operation of the loading mechanism can also be stopped, and an alarm can be issued to prevent accidents. Fence 5 can also be equipped with a display screen to display various operating parameters of the equipment, facilitating adjustments. Fence 5 can also be equipped with a start / stop button to control the start and stop of related devices and structures.

[0041] See also Figure 2-11 In one embodiment of the present invention, the flow tray 1 flows along with the conveyor line 7 and is used to carry processed products for circulation; the flow tray 1 can be a rectangular plate-like structure, which includes at least a flat bottom surface, the size of which is larger than the size between the two support frames of the conveyor line 7, so that it can flow smoothly on the conveyor line 7. The flow tray 1 is provided with a placement position for accommodating the steering knuckle, and the placement position can be a groove-type structure that matches the steering knuckle, or it can be provided with a clamping assembly for fixing the steering knuckle located thereon to ensure the stability of the steering knuckle during the entire production process. When the steering knuckle is located in the placement position on the flow tray 1, the two bearing holes of the steering knuckle are located at the upper and lower ends respectively. The posture of the steering knuckle on the flow tray 1 is as follows Figure 1 shown.

[0042] See also Figure 2-11In one embodiment of the present invention, the lifting plate 3 is arranged between the two brackets of the conveyor line 7, and the size of the lifting plate 3 is smaller than the size between the two brackets. The lifting plate 3 is connected to the first linear drive component 8; the first linear drive component 8 is used to drive the lifting plate 3 to rise or fall. Under normal conditions, the lifting plate 3 is lower than the height of the top of the conveyor line 7, which does not affect the flow of the transfer pallet. When the flow pallet 1 flows to the top of the lifting plate 3, the lifting plate 3 lifts the flow pallet 1 so that the flow pallet 1 is separated from the conveyor line 7 for subsequent pressing. A plurality of top blocks are provided on the top surface of the lifting plate 3. The top blocks can be cylindrical and are respectively arranged at the edge positions of the lifting plate 3. The stability of the lifting process of the flow pallet 1 is ensured by setting the top blocks.

[0043] See also Figure 2-11 In one embodiment of the present invention, the flow tray 1 may be provided with a plurality of positioning holes, and the lifting plate 3 may be provided with positioning pins 9. The positioning pins 9 may also be provided at the top of a cylindrical top block. When the lifting plate 3 rises to lift the flow tray 1, the positioning pins 9 flexibly engage with the positioning holes for positioning, ensuring the positional accuracy of the flow tray 1 at the lifting position, thereby ensuring the accuracy of the subsequent inner ring assembly and placement. To ensure the positional accuracy of the flow tray 1 during its rest and lifting, a positioning blocking structure 10 (such as a vertically arranged telescopic rod, which, when blocking is required, rises above the conveyor line 7 and retracts below the conveyor line 7 to release the flow tray 1) may be provided. This structure may be driven by a pneumatic cylinder to stop the flow tray 1 at this position when it is transferred along the conveyor line 7. This effectively ensures the accuracy of the position at which the flow tray 1 stops lifting. After the inner ring is assembled, the blocking member is released, allowing it to continue to flow downward. The blocking member may also be driven by a pneumatic cylinder or other power source to rotate within a certain angle to achieve blocking, stopping, and positioning of the flow tray 1.

[0044] See also Figure 2-11 In one embodiment of the present invention, a positioning shaft 13 can be fixedly provided on the top surface of the lifting plate 3, and a through hole is provided on the bottom surface of the flow tray 1. The through hole is consistent with the hole position of the steering knuckle for accommodating the bearing hole. When the lifting plate 3 rises to lift the flow tray 1, the positioning shaft 13 can rise synchronously with the lifting plate 3 and then be inserted into the hole position between the two bearing holes of the steering knuckle to achieve secondary precision positioning of the steering knuckle. As another example, the positioning shaft 13 can be set through the lifting plate 3 and driven up and down by another cylinder.

[0045] See also Figure 2-11In one embodiment of the present invention, the gripping mechanism 11 is used to clamp the inner diameter of the bearing inner ring; the gripping mechanism 11 may include a plurality of clamping jaws distributed in a cylindrical shape and a power assembly, and the power assembly is used to drive the clamping jaws to open. Specifically, as an example, the power assembly may be a cylinder, and the number of the clamping jaws may be three. The clamping jaws are rotatably arranged on a movable seat, and the clamping jaws can be driven to open by the cylinder. The three clamping jaws are distributed in a ring shape, and there are gaps between adjacent clamping jaws. The outer wall of the clamping jaws is a curved surface structure. When in use, the clamping jaws are first in a retracted state, and then move to the through-hole position of the bearing inner ring. Then the clamping jaws open, and the outer wall of the clamping jaws abuts against the inner wall of the inner ring through-hole, completing the clamping operation of the bearing inner ring.

[0046] See also Figure 2-11 In one embodiment of the present invention, the drive mechanism 12 is used to drive the gripping mechanism 11 in both horizontal and vertical directions; that is, it is used to drive the movable base and the clamping jaws in both horizontal and vertical directions. The drive mechanism 12 may be a truss manipulator structure. Specifically, as an example, the drive mechanism 12 may include a second linear drive assembly and a third linear drive assembly. The second and third linear drive assemblies are arranged in an intersecting manner and are used to drive the movable base in both horizontal and vertical directions, respectively. The clamping jaws are provided on the movable base to clamp the inner ring of the bearing. Specifically, the second linear drive assembly may be mounted on the support body 2 and connected to the third linear drive assembly via a slide, enabling horizontal and vertical movement of the third linear drive assembly. The third linear drive assembly is used to drive the movable base in both horizontal and vertical directions. The second and third linear drive assemblies provide the movable base with freedom of movement in both horizontal and vertical directions. Specifically, the second and third linear drive assemblies may be ball screw structures, or they may be slide rails and slide seats, powered by pneumatic cylinders. Other linear motion structures may also be used, without limitation.

[0047] See also Figure 2-11In one embodiment of the present invention, the silo 4 is located to the side of the conveyor line 7 and is used to store bearing inner rings to be assembled. Specifically, as an example, the silo 4 includes a base plate and retaining rods fixed to the base plate. The base plate can be circular and horizontally arranged. Multiple sets of retaining rods are arranged vertically along the circumference of the base plate to retain multiple stacked, vertically columnar bearing inner rings. The stacked bearing inner rings are stacked with their axes vertical. Multiple sets of retaining rods are provided; each set can contain at least three retaining rods. The inscribed circle of the retaining rods in the set matches or is slightly larger than the outer diameter of the bearing inner rings, thereby forming a space between the multiple retaining rods in the set to accommodate the stacked bearing inner rings. The number of retaining rods in each set should not be too large, as this would increase the difficulty of unloading the materials and the difficulty of grasping them by the robot arm. Preferably, the number is three or four. Furthermore, a power source can be provided at the bottom of the silo 4 to drive the intermittent rotation of the silo 4. This allows the base plate to rotate continuously, facilitating material discharge and positioning of the material near the gripping mechanism 11, facilitating its grasping and loading. The specific structure of the power source is not limited, as long as it can drive the base plate to rotate intermittently. For example, this can be driven by a servo motor, which is controlled by a PLC control system, thereby controlling the angle of each rotation of the base plate. Other intermittent rotation structures, such as cam structures and grooved wheel mechanisms, can also be used.

[0048] See also Figure 2-11 In one embodiment of the present invention, the device further includes a grease injection mechanism, which includes a grease injection head 14 and a power structure 16 for driving the grease injection head 14 to move horizontally and vertically. The power structure 16 may include a horizontally arranged cylinder and a vertically arranged cylinder, the horizontally arranged cylinder is used to drive the longitudinally arranged cylinder to move horizontally, and the longitudinally arranged cylinder is used to drive the grease injection head 14 to move longitudinally. The grease injection head 14 may be connected to a container for containing grease through a pipeline. The grease injection head 14 may be provided with an air-controlled grease injection valve 17 for controlling the opening and closing of the outlet of the grease injection head 14. Furthermore, the grease injection head 14 may be provided with a grease flowmeter 15 for quantitative grease injection. The grease injection head 14 may be provided with a single outlet, and preferably, a plurality of grease injection outlets are distributed circumferentially at the lower end of the grease injection head 14. Grease is injected on the inner wall of the outer ring of the bearing using multiple outlets.

[0049] In one embodiment of the present invention, an oil receiving pan is further provided, and the oil receiving pan is arranged below the grease injection head 14 to prevent grease from dripping and contaminating the grease injection head 14. Preferably, a cylinder is provided to drive the oil receiving pan to move linearly. Initially, the end of the oil receiving pan is located at the side of the steering knuckle and below the grease injection head 14. After the grease injection head 14 completes the grease injection action in the steering knuckle, the grease injection head 14 rises and separates from the steering knuckle. At this time, the oil receiving pan extends to the bottom of the grease injection head 14 to prevent grease from dripping. Then the grease injection head 14 returns to its original position and separates from the space above the steering knuckle to facilitate the subsequent placement of the inner ring. At the same time, the oil receiving pan and the grease injection head 14 are reset synchronously and are always ensured to be located below the grease injection head 14 to prevent grease from dripping and contaminating the grease injection head 14.

[0050] Working principle of the present invention:

[0051] The working process of this equipment can be carried out under the control of a control system (such as a PLC control system). The working process of automatic grease injection and automatic inner ring assembly is as follows:

[0052] Initially, the lifting plate 3 is in a low position, and the positioning shaft 13 is in a low position, that is, below the height of the conveyor line 7. When the flow tray 1, carrying the steering knuckle with the bearing outer ring pressed, flows along the conveyor line 7 to the top of the lifting plate 3, the flow tray 1 is stopped in the lifting position by the action of the blocking structure 10, and the blocking structure 10 has a blocking and positioning effect. Then, the lifting plate 3 rises, lifting the flow tray 1 off the conveyor line 7. During this process, the positioning shaft 13 is inserted into the hole between the two bearing holes of the steering knuckle, achieving secondary precision positioning. After the transfer tray 1 is lifted, the grease head 14, driven by the power structure 16, first moves horizontally to just above the steering knuckle. It then moves downward until its outlet is located inside the bearing outer ring, dispensing a fixed amount of grease onto the inner wall of the bearing outer ring. Once grease is complete, the grease head 14 moves upward and away from the steering knuckle. Simultaneously, the oil receiving pan extends above the steering knuckle and below the grease head 14. The grease head 14 then retracts and returns to its original position, along with the oil receiving pan. This completes the process of quantitative grease injection.

[0053] Driven by the drive mechanism 12, the gripper of the gripping mechanism 11 first moves directly above the inner ring stacking column in the hopper 4, then moves downward to the topmost inner ring. At this point, the gripper is positioned inside the through-hole of the topmost bearing inner ring. The gripper then opens, abutting the inner wall of the through-hole, securing the topmost bearing inner ring. The gripper then moves upward, clearing the confining rod area of ​​the hopper 4, and then laterally out of the hopper 4. This completes the gripping process for the bearing inner ring, which can be performed simultaneously with the metered grease injection process. After the inner ring is captured, the drive mechanism 12 drives the gripper to move horizontally to directly above the steering knuckle. Then, it moves downward to the knuckle's bearing hole, where the gripper retracts, placing the bearing inner ring inside the greased outer ring. This completes the assembly of the topmost bearing inner ring. The gripper 11 then disengages from the steering knuckle, and the flow tray 1 drops onto the conveyor line 7. Simultaneously, the blocking structure 10 releases its blockage on the flow tray 1, allowing it to be transferred along the conveyor line 7 to the next process step. Subsequently, the retainer can be installed first, and then the steering knuckle can be turned over to complete the assembly of the bearing inner ring at the other end.

[0054] After the flow tray 1 is in place, it stops and is lifted off the conveyor line 7. At the same time, the RFID information is read to confirm the product-related information. The cycle time is 4 seconds. During this process, a sensor can be installed at the side to detect whether there is a steering knuckle workpiece on the pallet. A pallet presence detection sensor can be installed at the position of the conveyor line 7 corresponding to the lifting plate 3. Two sensors can be arranged diagonally opposite each other to detect whether the flow tray 1 is present at the press position.

[0055] Next, the positioning shaft 13 rises, completing the secondary fine positioning of the product. This process takes approximately 3 seconds. The grease injection head 14, driven by a pneumatic cylinder, then descends, injecting a fixed amount of grease onto the bearing outer ring. Upon completion, it rises and resets. This process takes 10 seconds. When the robot grasps the bearing inner ring, sensors can be installed in the gripper to detect the presence of the inner ring and the orientation of the inner ring components to prevent press-fitting errors. The grasping process takes 4 seconds and can be performed simultaneously with the greasing process. The robot moves to a position above the flow tray 1, places the bearing inner ring inside the outer ring, and resets it. This process takes 6 seconds. After greasing and inner ring assembly, the positioning shaft 13 descends and resets, and the lifting plate 3 descends and resets. This process takes 3 seconds. The flow tray 1 then moves to the next station, taking another 3 seconds. Specifically, the automated assembly of bearing inner rings using this solution results in a press-fitting time of 29 seconds per piece.

[0056] The above-mentioned sensor may be a photoelectric sensor, a proximity sensor, an optical sensor or other types of sensors, such as an infrared sensor.

[0057] The present application is provided with a grease injection head 14, which is driven by a power mechanism to move horizontally and vertically. A control valve and flow meter are provided at the position of the grease injection head 14, which can automatically and quantitatively inject grease into the inner side of the bearing outer ring of the steering knuckle. A material grabbing mechanism 11 is provided to automatically grab the bearing inner ring from the hopper 4 and place the bearing inner ring inside the bearing outer ring on the grease injection outer wall, completing the automated grease injection and inner ring assembly of the steering knuckle. This solves the problems existing in the prior art of manual labor, low assembly efficiency, high proficiency requirements for staff, difficulty in ensuring assembly quality, and difficulty in ensuring quality consistency between different products.
