[0055] In this invention, during operation, the operator stacks the motor rear covers in the rear cover receiving fixture of the indexing turntable mechanism, and places the motor body on the motor body placement platform. The rotation of the indexing turntable mechanism moves one of the rear cover receiving fixtures to the working position. The moving platform of the lifting and translating mechanism, through a lateral floating adjustment mechanism, moves the adsorption mechanism above the working position. After the adsorption mechanism adsorbs the motor rear cover, the lifting and translating mechanism moves the adsorption mechanism to above the motor body placement platform. The lateral floating adjustment mechanism adjusts the lateral position once to align the motor rear cover with the motor body. After assembly, this lateral position setting remains unchanged, and it can be used again in subsequent assembly processes as long as the position of the motor body placement platform remains unchanged. The entire process achieves multi-station motor rear cover supply through the indexing turntable mechanism, solving the problem of low efficiency in manual material handling; the lifting and translating mechanism enables the adsorption mechanism to move horizontally and vertically, solving the problem of transporting the motor rear cover from the material handling station to the assembly station; and the lateral floating adjustment mechanism's floating adjustment section sets the lateral position once, solving the problem of adaptability to differences in assembly positions between different devices. The synergistic effect of these technical features has enabled the automation of motor rear cover loading and assembly, improving production efficiency and assembly accuracy.
[0056] Furthermore, the chassis is rotatably mounted on the frame and equipped with locking holes. This, combined with the structure of the telescopic drive, swing plate, and movable telescopic actuator, enables the intermittent rotation and positioning of the indexing turntable, ensuring the rear cover accurately rotates to the working position to accommodate the tooling. The loading and lifting mechanism, through the cooperation of the lifting drive source, lifting guide rail, lifting guide block, lifting nut, lifting screw, and lifting rod, lifts the topmost motor rear cover of the stack to an appropriate height, facilitating gripping by the adsorption mechanism and avoiding positional deviations during adsorption. The combined configuration of the horizontal and vertical moving mechanisms allows the lifting and translation mechanism to move precisely in three-dimensional space, achieving accurate positioning of the adsorption mechanism from the material handling station to the assembly station. The lateral floating adjustment mechanism, through the cooperation of the upper fixed plate, lower floating plate, vertical fixing component, and floating shaft, allows for small-amplitude lateral adjustments during assembly. After adjustment, the position remains fixed, adapting to the assembly position requirements of different motor bodies.
[0057] In summary, this utility model achieves automated feeding and precise assembly of the motor rear cover through the coordinated operation of the indexing turntable mechanism, the lifting and translation mechanism, the lateral floating adjustment mechanism, and the adsorption mechanism. This significantly improves production efficiency and reduces manual labor intensity. At the same time, the one-time lateral adjustment function enhances the adaptability and assembly accuracy of the equipment, demonstrating good practicality and economic benefits.

[0069] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0070] like Figure 1-11 As shown, a motor rear cover feeding mechanism includes:
[0071] Rack 1;
[0072] Indexing turntable mechanism 2 is rotatably mounted on frame 1. Indexing turntable mechanism 2 includes multiple rear cover receiving fixtures 21 distributed at equal intervals along the circumference. The rear cover receiving fixtures 21 are suitable for carrying stacked motor rear covers. Indexing turntable mechanism 2 is provided with working station.
[0073] Motor body placement platform 3 is mounted on frame 1;
[0074] Lifting and translating mechanism 4 is mounted on frame 1 and is equipped with a moving platform 41.
[0075] The lateral floating adjustment mechanism 5 is installed on the moving platform 41 of the lifting and translation mechanism 4. The lateral floating adjustment mechanism 5 is provided with a floating adjustment part suitable for lateral adjustment.
[0076] Adsorption mechanism 6 is installed on the floating adjustment part of the transverse floating adjustment mechanism 5;
[0077] Among them, the lifting and translation mechanism 4 is adapted to drive the adsorption mechanism 6 to adsorb the motor rear cover located at the working position of the indexing turntable mechanism 2 and move it to the motor body on the motor body placement platform 3 through the horizontal floating adjustment mechanism 5.
[0078] In this embodiment, during operation, the operator stacks the motor rear covers in the rear cover receiving fixture 21 of the indexing turntable mechanism 2, and places the motor body on the motor body placement platform 3. The indexing turntable mechanism 2 rotates, causing one of the rear cover receiving fixtures 21 to rotate to the working position. The moving platform 41 of the lifting and translating mechanism 4 drives the adsorption mechanism 6 to move above the working position through the lateral floating adjustment mechanism 5. After the adsorption mechanism 6 adsorbs the motor rear cover, the lifting and translating mechanism 4 drives the adsorption mechanism 6 to move the motor rear cover above the motor body placement platform 3. The lateral position is adjusted in one go by the lateral floating adjustment mechanism 5 to align the motor rear cover with the motor body. After the assembly is completed, this lateral position setting remains unchanged. In subsequent assembly processes, as long as the position of the motor body placement platform 3 remains unchanged, this position can continue to be used. The entire process utilizes the indexing turntable mechanism 2 to achieve multi-station motor back cover supply, solving the problem of low efficiency caused by manual material handling; the lifting and translation mechanism 4 enables the adsorption mechanism 6 to move horizontally and vertically, solving the problem of transporting the motor back cover from the material handling station to the assembly station; and the floating adjustment part of the lateral floating adjustment mechanism 5 allows for one-time lateral position setting, solving the problem of adaptability to differences in assembly positions between different equipment. The synergistic effect of these technical features automates the motor back cover loading and assembly, improving production efficiency and assembly accuracy.
[0079] Specifically, the indexing turntable mechanism 2 includes:
[0080] The chassis 22 is rotatably mounted on the frame 1, and the chassis 22 is provided with a plurality of engagement holes 221 spaced out in the circumferential direction.
[0081] Telescopic drive component 23, one end of which is hinged to the frame 1, and the telescopic drive component 23 is provided with a drive end;
[0082] The swing plate 24 is coaxially hinged to the chassis 22 on the frame 1, and one end of the swing plate 24 is hinged to the drive end of the telescopic drive component 23.
[0083] The movable telescopic actuator 25 is mounted on the other end of the swing plate 24. The movable telescopic actuator 25 is provided with a telescopic end and is adapted to extend and retract so that the telescopic end can be selectively inserted into the engagement hole 221.
[0084] The rear cover receiving fixture 21 is installed at intervals along the circumference of the chassis 22. The telescopic drive component 23 is adapted to drive the swing plate 24 to swing when the movable telescopic driver 25 is inserted into the engagement hole 221, and at the same time drive the chassis 22 to rotate by a preset angle.
[0085] Specifically, the motor rear cover feeding mechanism also includes a limiting telescopic device 26, which is mounted on the frame 1. The limiting telescopic device 26 is adapted to extend and retract so that its telescopic end passes through the frame 1 and is inserted into the engagement hole 221, thereby limiting the rotation of the chassis 22.
[0086] In this embodiment, during the operation of the indexing turntable mechanism 2, when indexing rotation is required, the movable telescopic actuator 25 is activated first. The movable telescopic actuator 25 can be a cylinder, or in some embodiments, a hydraulic cylinder or an electric push rod, etc., a linear drive device. Its telescopic end extends through the arc-shaped groove on the frame 1 and inserts into the corresponding engaging hole 221 on the chassis 22 to achieve positioning and locking of the chassis 22. Subsequently, the telescopic drive component 23 starts to work. The telescopic drive component 23 is a cylinder, and its drive end pushes the swing plate 24 to swing around the hinge point. Since the middle part of the swing plate 24 is coaxially hinged with the chassis 22, the swing of the swing plate 24 drives the chassis 22 to rotate around its axis by a preset angle, thereby realizing the intermittent rotation of the indexing turntable.
[0087] The limiting telescopic device 26 plays a role in the positioning of the indexing turntable mechanism 2. The limiting telescopic device 26 can be a cylinder. When the chassis 22 rotates to the correct position, the telescopic end of the limiting telescopic device 26 passes through the frame 1 and inserts into the corresponding engaging hole 221 to lock the chassis 22 and prevent displacement of the chassis 22 during operation. A pair of limiting mechanisms 27 are respectively installed on both sides of the swing plate 24 on the frame 1. Each limiting mechanism 27 includes a fixing block fixed to the bottom of the frame 1 and an abutment rod threadedly connected to the fixing block. By adjusting the extension length of the abutment rod, the swing angle range of the swing plate 24 can be adjusted to ensure the accurate rotation angle of the chassis 22.
[0088] In the structural design of the rear cover receiving fixture 21, each fixture consists of two opposing baffles vertically fixed on the bottom panel. The inner sides of the opposing baffles are machined with arc surfaces that match the shape of the motor rear cover, so that the motor rear cover can be stably constrained between the two baffles. The number of rear cover receiving fixtures 21 is eight. In some embodiments, the number of rear cover receiving fixtures 21 is not limited to eight and can be set according to specific needs. In addition, this embodiment also includes a distance sensor, which is installed on the frame 1 on one side of the rear cover receiving fixture 21 at the working station. The height of the distance sensor is set to be higher than the height of the baffles. When the motor rear covers stacked in the rear cover receiving fixture 21 are removed by the lifting and translation mechanism 4 in conjunction with the adsorption mechanism 6, the distance sensor detects the distance change and triggers a signal to provide workpiece status feedback to the controller.
[0089] Specifically, the bottom of the rear cover receiving fixture 21 is provided with a through hole 211, and the bottom of the indexing turntable mechanism 2 is provided with lifting holes that are spaced apart along the circumference and correspond one-to-one with the rear cover receiving fixture 21.
[0090] The motor rear cover feeding mechanism also includes a feeding lifting mechanism 7, which includes:
[0091] A lifting drive source 71 is mounted on the frame 1.
[0092] Lifting guide rail 72 is vertically mounted on frame 1;
[0093] The lifting guide block 73 is slidably mounted on the lifting guide rail 72.
[0094] The lifting nut 74 is fixedly mounted on the lifting guide block 73.
[0095] The lifting screw 75 is rotatably mounted on the frame 1, and the lifting screw 75 is threadedly engaged with the lifting nut 74.
[0096] The lifting rod 76 is fixedly connected to the lifting guide block 73 at its lower end.
[0097] Among them, the lifting drive source 71 is adapted to drive the lifting screw 75 to rotate so as to drive the lifting guide block 73 to move up and down along the lifting guide rail 72, and lift the motor back cover stacked on the working position through the lifting rod 76 passing through the lifting hole and the through hole 211.
[0098] In this embodiment, during the operation of the material lifting mechanism 7, the lifting drive source 71 can be a motor. When it is necessary to lift the motor back covers stacked on the working station, the lifting drive source 71 drives the transmission belt to rotate through the drive wheel on its drive end. The transmission belt drives the driven wheel installed at the lower end of the lifting screw 75 to rotate, thereby driving the lifting screw 75 to rotate. The rotation of the lifting screw 75 converts the rotational motion into linear motion through the threaded engagement with the lifting nut 74, pushing the lifting guide block 73, which is fixed with the lifting nut 74, to rise along the lifting guide rail 72. The rise of the lifting guide block 73 drives the lifting rod 76, which is fixedly connected to it, to rise synchronously.
[0099] During the upward movement, the upper end of the lifting rod 76 passes through the lifting hole corresponding to the bottom of the indexing turntable mechanism 2 and the through hole 211 at the bottom of the rear cover receiving fixture 21 in sequence, and directly acts on the bottom of the motor rear cover stacked in the rear cover receiving fixture 21, lifting the uppermost motor rear cover to an appropriate height, so that the lifting and translation mechanism 4 can cooperate with the adsorption mechanism 6 to grab it.
[0100] In addition, this embodiment is provided with a pair of contact sensors, which are respectively set at the starting position and the ending position of the lifting guide rail 72. During the movement, the blocking block on the lifting guide block 73 blocks the contact sensor at the corresponding position in sequence. The controller determines the accurate position of the lifting guide block 73 through the signal feedback of the contact sensor, thereby controlling the start and end of the lifting stroke and preventing the lifting rod 76 from overextending or retracting.
[0101] Specifically, the motor rear cover feeding mechanism also includes an adjusting mounting block 77, which is mounted on the lifting guide block 73 and has a dovetail groove.
[0102] The lower end of the lifting rod 76 is provided with a guide part that cooperates with the dovetail groove, and the lifting rod 76 is adapted to move linearly along the dovetail groove through the guide part.
[0103] In this embodiment, the adjusting mounting block 77 is mounted on the lifting guide block 73. The adjusting mounting block 77 is machined with a dovetail groove, which has an inverted trapezoidal cross-section. The lower end of the lifting rod 76 is machined with a guide portion that matches the dovetail groove. The cross-sectional shape of the guide portion corresponds to the narrow end of the dovetail groove, allowing it to slide within the dovetail groove.
[0104] When the lifting rod 76 needs to be adjusted in position, the guide part moves linearly along the length of the dovetail groove to adjust the horizontal position of the lifting rod 76 relative to the lifting guide block 73.
[0105] Specifically, the lifting and translation mechanism 4 includes a horizontal moving mechanism mounted on the frame 1 and a vertical moving mechanism mounted on the horizontal moving mechanism.
[0106] Specifically, the horizontal movement mechanism includes:
[0107] Two horizontal guide rails 421 are horizontally mounted on the frame 1;
[0108] Horizontal slider 422 is slidably mounted on horizontal guide rail 421;
[0109] A horizontal telescopic drive source 423 is mounted on the frame 1. The telescopic end of the horizontal telescopic drive source 423 is fixedly connected to the horizontal slider 422. The horizontal telescopic drive source 423 is suitable for driving the horizontal slider 422 to move horizontally along the horizontal guide rail 421.
[0110] In this embodiment, the horizontal telescopic drive source 423 can be a cylinder, or in some embodiments it can be a hydraulic cylinder or an electric push rod or other linear drive device. Its cylinder body or fixed end is mounted on the frame 1 by a bracket, and the telescopic end is fixedly connected to the horizontal slider 422 by a connector.
[0111] When the horizontal telescopic drive source 423 is working, the extension or retraction of its telescopic end directly pushes or pulls the horizontal slider 422 to move horizontally along the horizontal guide rail 421, thereby driving the subsequent mechanism mounted on the horizontal slider 422 to move in the horizontal direction. Stops are provided at the starting and ending positions of the horizontal guide rail 421, and the stops are fixed to the guide rail or the frame 1 by bolts. When the horizontal slider 422 moves to the end of its stroke, the stops act as mechanical limiters to prevent the horizontal slider 422 from exceeding its designed stroke range.
[0112] Specifically, the vertical movement mechanism includes:
[0113] Base plate 431, base plate 431 is mounted on the horizontal moving mechanism;
[0114] Vertical guide nut 432 is fixedly mounted on base plate 431;
[0115] Vertical screw 433, which is threadedly engaged with vertical guide nut 432;
[0116] Upper bearing plate 434 is installed on the upper end of vertical screw 433;
[0117] Four vertical guide posts 435 are slidably mounted on the base plate 431 in the vertical direction, and the upper end of the vertical guide post 435 is fixedly connected to the upper bearing plate 434.
[0118] A rotary drive source 436 is mounted on an upper support plate 434. The rotary drive source 436 is connected to a vertical screw 433. The rotary drive source 436 is adapted to drive the vertical screw 433 to rotate so as to drive the upper support plate 434 to move up and down along the vertical guide column 435.
[0119] The mobile platform 41 is installed at the lower end of the vertical screw 433 and is fixedly connected to the lower end of the vertical guide post 435.
[0120] In this embodiment, in the working principle of the vertical moving mechanism, the base plate 431 is installed on the horizontal slider 422 of the horizontal moving mechanism by bolts or other fasteners, providing a mounting base for the entire vertical moving mechanism. The vertical guide nut 432 is fixedly installed on the base plate 431, and its internal thread mates with the external thread of the vertical screw 433.
[0121] The rotary drive source 436 can be an electric motor, or in some embodiments, an engine, a hydraulic motor, or a combination of one of these with a reducer, etc., mounted on the upper support plate 434. The rotary drive source 436 is connected to the vertical screw 433 via a coupling. When the rotary drive source 436 is working, it drives the vertical screw 433 to rotate. Since the vertical screw 433 is threadedly engaged with the fixed vertical guide nut 432, the rotation of the screw is converted into linear motion of the upper support plate 434, causing the upper support plate 434 to rise and fall vertically.
[0122] The lower end of the vertical guide column 435 passes through the base plate 431 and is fixedly connected to the moving platform 41, while the upper end is fixedly connected to the upper bearing plate 434. It serves as a guide during the lifting and lowering of the upper bearing plate 434, preventing it from deflecting or swaying. The moving platform 41 is also installed at the lower end of the vertical screw 433 and connected to the screw via a bearing, allowing the moving platform 41 to move up and down with the rotation of the vertical screw 433, but not to rotate with the screw itself.
[0123] Specifically, the lateral floating adjustment mechanism 5 includes:
[0124] The upper fixed plate 51 is installed on the moving platform 41 of the lifting and translation mechanism 4. The upper fixed plate 51 is provided with a first through hole and a second through hole.
[0125] The lower floating plate 52 is located below the upper fixed plate 51;
[0126] Four vertical fixing members 53 are provided. The vertical fixing members 53 pass through the first through hole and are threadedly connected to the lower floating plate 52. The outer diameter of the vertical fixing members 53 is smaller than the diameter of the first through hole.
[0127] The floating shaft 54 passes through the second through hole and is fixedly connected to the lower floating disk 52. The outer diameter of the floating shaft 54 is smaller than the diameter of the second through hole, and the upper end of the floating shaft 54 forms a flat part.
[0128] A floating adjustment block 55 is mounted on the upper fixed plate 51. The floating adjustment block 55 is provided with a square groove 551 that mates with the flat part of the floating shaft 54.
[0129] The floating shaft 54 is adapted to adjust the position of the lower floating disk 52 along the length of the square groove 551, and the floating adjustment part is provided on the lower floating disk 52.
[0130] In this embodiment, in the structure of the lateral floating adjustment mechanism 5, the upper fixed plate 51 is fixedly mounted on the moving platform 41 of the lifting and translating mechanism 4 by bolts. The upper fixed plate 51 is machined with a first through hole and a second through hole, the diameters of which respectively cooperate with the corresponding fixing parts and shafts. The lower floating plate 52 is located below the upper fixed plate 51, and a certain gap is maintained between the two plates, allowing the lower floating plate 52 to move slightly relative to the upper fixed plate 51 in the horizontal direction.
[0131] The vertical fixing member 53 can be a bolt or screw or other fastener. Its lower end is threaded to the lower floating plate 52, and its upper end passes through the first through hole of the upper fixed plate 51. Since the outer diameter of the vertical fixing member 53 is smaller than the diameter of the first through hole, a radial gap is formed between the first through hole and the vertical fixing member 53. This gap allows the lower floating plate 52 to float and adjust relative to the upper fixed plate 51 in the horizontal direction. The lower end of the floating shaft 54 is fixedly connected to the lower floating plate 52, and its upper end passes through the second through hole. The outer diameter of the floating shaft 54 is also smaller than the diameter of the second through hole, forming a radial gap.
[0132] The upper end of the floating shaft 54 is machined into a flat portion. The floating adjustment block 55 is mounted on the upper fixed plate 51, and its interior is machined with a square groove 551 that matches the flat portion of the floating shaft 54. When it is necessary to adjust the horizontal position of the lower floating plate 52, the vertical fixing member 53 can be loosened, allowing the flat portion of the floating shaft 54 to slide along its length within the square groove 551, thereby driving the lower floating plate 52 to move in the corresponding direction, achieving precise adjustment of the lateral position.
[0133] Specifically, the motor rear cover feeding mechanism also includes a hollow rotating platform 8, which includes a fixed base and a rotating table. The fixed base is installed on the moving platform 41 of the lifting and translation mechanism 4.
[0134] A rotary driver 81 is mounted on a fixed base and is adapted to drive the rotary table to rotate.
[0135] The adsorption mechanism 6 is installed on the rotating platform.
[0136] In this embodiment, the hollow rotating platform 8 is existing technology and will not be described in detail. The rotating driver 81 can be a servo motor, a stepper motor, or a pneumatic motor. When the rotating driver 81 is working, it drives the rotating table to rotate around its axis, thereby adjusting the angle of the adsorption mechanism 6 mounted on the rotating table.
[0137] The adsorption mechanism 6 includes three suction cups, which are mounted on the rotating table via a bracket. The suction cups are connected to the vacuum pump via vacuum lines. When it is necessary to adsorb the motor back cover, the vacuum pump works to generate negative pressure, so that the suction cups can be firmly adsorbed onto the surface of the motor back cover.
[0138] The upper fixed plate 51 is equipped with two push rods, the positions of which correspond to the slots on the motor rear cover. While the suction mechanism 6 is adsorbing the motor rear cover, the push rods are inserted into the slots on the motor rear cover to provide additional positioning, ensuring the positional stability of the motor rear cover during transportation and preventing positional shifts that may occur when relying solely on suction cup adsorption.
[0139] The complete operation process of the motor rear cover loading mechanism is as follows: The operator first stacks multiple motor rear covers in the respective rear cover receiving fixtures 21 of the indexing turntable mechanism 2. Each fixture can accommodate multiple stacks of motor rear covers. At the same time, the motor body to be assembled is placed on the motor body placement platform 3. After the equipment is started, the indexing turntable mechanism 2 first performs indexing and positioning. The telescopic end of the movable telescopic drive 25 is inserted into the corresponding engagement hole 221 on the chassis 22. Then, the telescopic drive component 23 pushes the swing plate 24 to swing, causing the chassis 22 to rotate at a preset angle, so that one of the rear cover receiving fixtures 21 rotates to the working position.
[0140] Once the work station is determined, the telescopic end of the limit telescopic device 26 inserts into the corresponding engaging hole 221 to lock and position the chassis 22. The loading and lifting mechanism 7 starts working, with the lifting drive source 71 driving the lifting screw 75 to rotate, causing the lifting guide block 73 to rise along the lifting guide rail 72. The lifting rod 76 passes through the lifting hole and through hole 211, lifting the topmost motor rear cover stacked at the work station to an appropriate height. At this time, the horizontal movement mechanism in the lifting and translating mechanism 4 works first, with the horizontal telescopic drive source 423 driving the horizontal slider 422 to move along the horizontal guide rail 421, moving the entire lifting and translating mechanism 4 above the work station.
[0141] Subsequently, the vertical moving mechanism operates, with the rotary drive source 436 driving the vertical screw 433 to rotate, causing the moving platform 41 to descend to a suitable height, bringing the three suction cups of the adsorption mechanism 6 close to the lifted motor rear cover. The vacuum pump starts, generating negative pressure within the suction cups through the vacuum lines, firmly adsorbing the motor rear cover. Simultaneously, two push rods on the upper fixed plate 51 insert into the slots in the motor rear cover, providing additional positioning support. After adsorption is complete, the vertical moving mechanism drives the moving platform 41 to rise, causing the motor rear cover to detach from the lifting rod 76.
[0142] Next, the horizontal moving mechanism operates, moving the lifting and translating mechanism 4, which holds the motor rear cover, above the motor body placement platform 3. According to assembly process requirements, the rotary driver 81 drives the rotary table of the hollow rotary platform 8 to rotate, adjusting the angle and orientation of the motor rear cover. The vertical moving mechanism then operates again, lowering the moving platform 41 and accurately positioning the motor rear cover onto the motor body. Before this process, the lateral floating adjustment mechanism 5 functions, adjusting the lateral position of the lower floating disk 52 along its length within the square groove 551 via the floating shaft 54, ensuring precise alignment between the motor rear cover and the motor body. After this initial position setting, the lateral position remains fixed, and this set position can be used continuously during subsequent assembly processes as long as the position of the motor body placement platform 3 remains unchanged.
[0143] After assembly, the vacuum pump stops working, the suction cup releases its adsorption on the motor rear cover, the push rod exits the slot, and the lifting and translating mechanism 4 rises and returns to its initial position. The distance sensor detects that the motor rear cover at the working station has been removed and sends a signal to the controller. Subsequently, the loading and lifting mechanism 7 resets, and the lifting rod 76 descends to its initial position. If there are still remaining motor rear covers in the rear cover accommodating fixture 21 at the current working station, the system continues to the next round of material handling and assembly cycle; if all motor rear covers in the current fixture have been removed, the indexing turntable mechanism 2 rotates, moving the next fixture containing a motor rear cover to the working station, and the entire material handling and assembly process continues.
[0144] In other embodiments, the number of tooling 21 accommodated in the rear cover can be adjusted according to production needs, and is not limited to eight. The number and arrangement of suction cups in the adsorption mechanism 6 can also be optimized according to the size and shape of the motor rear cover. The entire system can be configured with a controller for automated control. The controller can be a PLC, industrial computer, or dedicated controller, electrically connected to each drive source and sensor, receiving sensor feedback signals, and controlling each mechanism to act sequentially according to a preset program, thereby realizing the automated operation of the entire loading and assembly process.

It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
