Description

Technical Field

[0001] This utility model relates to the field of motor processing equipment technology, and in particular to a press-fitting device. Background Technology

[0002] Brushed motors consist of components such as a stator, rotor, and commutator, with the commutator press-fitted onto the motor shaft. During operation, the motor shaft rotates in conjunction with the carbon brushes. The friction generated by the rotating brushes produces carbon dust, which can easily splash to the outside and cause contamination. To prevent carbon dust from splashing to the outside, a common method is to press-fit a dust seal onto the motor shaft. This dust seal blocks the carbon dust from flying outwards.

[0003] Dust rings are thin sheet structures, and existing pressing equipment easily causes deformation during installation. Adding a shaping operation after pressing the dust rings would increase the process and require additional shaping equipment, thus increasing costs. Manual pressing of dust rings, on the other hand, is less efficient and has higher labor costs. Utility Model Content

[0004] The purpose of this invention is to provide a pressing device for reducing the degree of deformation of parts during the pressing process.

[0005] This utility model is achieved through the following technical solution:

[0006] A pressing device for pressing a part into a workpiece, the pressing device comprising:

[0007] A press-fitting station includes a press-fitting position, wherein the workpiece to be processed is positioned at the press-fitting position;

[0008] A clamping unit for clamping the part;

[0009] A drive unit is connected to the clamping unit and is used to drive the clamping unit to move toward the press-fit position, so that the part clamped by the clamping unit is pressed into the workpiece to be processed on the press-fit position;

[0010] The buffer unit includes a fixed-position limiting plate, and an elastic buffer and a rigid buffer connected to the drive unit. The elastic buffer and the rigid buffer can move synchronously with the drive unit and move towards the limiting plate during pressing. In its free state, the distance between the elastic buffer and the limiting plate is smaller than the distance between the rigid buffer and the limiting plate, so that the elastic buffer abuts against the limiting plate before the rigid buffer. When the elastic buffer abuts against the limiting plate, it buffers the movement of the drive unit, and when the rigid buffer abuts against the limiting plate, it restricts the further movement of the drive unit.

[0011] Furthermore, the elastic buffer includes a telescopic rod and an elastic element sleeved on the telescopic rod. The telescopic rod is used to abut against the limiting plate, and the telescopic rod can retract and squeeze the elastic element. The elastic force of the elastic element buffers the movement of the drive unit.

[0012] The rigid buffer is made of a rigid material and makes hard contact with the limiting plate to restrict further movement of the drive unit.

[0013] Furthermore, the buffer unit also includes a third buffer element, which is installed in the clamping unit. The third buffer element is driven by the driving unit to abut against the shaft end of the workpiece to be processed, and the third buffer element makes hard contact with both the workpiece to be processed and the driving unit to limit further movement of the driving unit.

[0014] Furthermore, the clamping unit includes a placement component and a clamping component. The placement component is used to accommodate the part, and the clamping component is fixedly accommodated within the placement component. The placement component is provided with a through cavity, and at least a portion of the third buffer component is accommodated within the through cavity. A portion of the workpiece to be processed passes through the part and makes hard contact with the third buffer component.

[0015] Furthermore, the clamping unit includes a placement member, which is provided with a receiving cavity for accommodating the part and a first opening and a second opening communicating with the receiving cavity;

[0016] The pressing equipment further includes a feeding unit, wherein the portion of the feeding unit used for mounting the part extends from outside the first opening into the receiving cavity, so that the part is accommodated in the receiving cavity;

[0017] The clamping member can extend into the receiving cavity from the second opening to clamp and fix the part.

[0018] Furthermore, the clamping unit includes a first mounting plate, the object placement component and the clamping component are respectively fixedly mounted on the first mounting plate, and the driving unit drives the object placement component, the clamping component and the first mounting plate to move synchronously.

[0019] Furthermore, the first opening and the second opening are located on different sides of the object, and the clamping member is used to press the part against the wall forming the receiving cavity.

[0020] Furthermore, the feeding unit includes a part support and a feeding drive for moving the part support; the pressing equipment also includes a feeding unit for supplying parts to the part support, and the part support is driven by the feeding drive to move the parts into the receiving cavity.

[0021] Furthermore, the feeding unit includes a guide block, which is provided with a guide groove extending along the moving direction of the part support and a loading groove communicating with the guide groove. The part support can be exposed in the loading groove to receive the part provided by the feeding unit. The part support is driven by the feeding drive to move along the guide groove.

[0022] Furthermore, the feeding unit includes a dispensing component and a transfer component. The dispensing component is used for dispensing and conveying parts, and the transfer component is installed on the side of the dispensing component adjacent to the feeding unit. The transfer component is used to move the parts on the dispensing component to the part support.

[0023] Furthermore, the material distribution assembly includes a vibratory feeder and a storage belt connected to the vibratory feeder. The vibratory feeder is used to generate vibration to distribute the parts. The storage belt extends from the vibratory feeder to the feeding unit, and the storage belt receives the parts after they have been distributed by the vibratory feeder and conveys the parts toward the feeding unit.

[0024] Furthermore, the pressing station includes a rotary seat and at least three positioning members mounted on the rotary seat. The positioning members are used to clamp and fix the workpiece to be processed. The rotary seat rotates to move the plurality of positioning members to the pressing station in sequence.

[0025] Furthermore, the pressing equipment also includes a transfer unit and a unloading unit. The transfer unit is used to reciprocate between the pressing station and the unloading unit to transfer the workpiece that has been pressed in the pressing station to the unloading unit for unloading.

[0026] Furthermore, the unloading unit includes an unloading position and a carrier located at the unloading position. The carrier is provided with a plurality of receiving slots, and the transfer unit transfers the workpiece to the receiving slot of the carrier located at the unloading position.

[0027] Multiple carriers are provided, and each carrier is connected to a transfer component. The transfer component is used to drive the carrier to move, so as to transfer an empty carrier to the unloading position or to move a carrier full of workpieces out of the unloading position.

[0028] Furthermore, the transfer unit is a four-axis robot, the workpiece to be processed is a motor shaft, and the part is a dustproof ring.

[0029] Compared with existing technologies, the advantages of this utility model are:

[0030] By ensuring that the distance between the elastic buffer and the limiting plate in its free state is smaller than the distance between the rigid buffer and the limiting plate, the elastic buffer will first contact the limiting plate, thus cushioning the movement of the drive unit and reducing its driving speed. Then, by using the rigid buffer, when the part is pressed into place, the rigid buffer contacts the limiting plate and forms a hard contact, thereby limiting further movement of the drive unit and preventing over-pressing of the part, ensuring the pressing accuracy. Furthermore, during the process of pressing the part into place without interference fit, the continuous use of elastic buffering with a continuously increasing buffering force further reduces the risk of deformation. Through the cooperation of the pressing station, clamping unit, drive unit, and buffering unit, the pressing equipment can achieve automated continuous pressing of parts, improving pressing efficiency.

Detailed Implementation

[0044] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0045] like Figures 1 to 12As shown, this utility model provides a press-fitting device for pressing a part 100 into a workpiece 200 to be processed. For example, part 100 is a dustproof ring, and workpiece 200 is a motor shaft. The press-fitting device is used to press the dustproof ring into the motor shaft. The press-fitting device includes a press-fitting station 1, a clamping unit 2, a driving unit 3, and a buffer unit 4. It may also include a feeding unit 5, a material supply unit 6, a transfer unit 7, and a unloading unit 8.

[0046] Further reference Figures 3 to 5 The press-fitting station 1 includes a press-fitting position 111, which is located below the clamping unit 2, and the workpiece 200 to be processed can be positioned at the press-fitting position 111. Specifically, the press-fitting station 1 may include a rotary seat 12 and at least three positioning members 14 mounted on the rotary seat 12. The positioning members 14 can be used to position the workpiece 200 to be processed, so that the workpiece 200 is fixed relative to the rotary seat 12. The rotary seat 12 may be a disc-shaped structure, and the rotary seat 12 may rotate around its center. When a positioning member 14 rotates to be directly below the clamping unit 2, the position of the positioning member 14 is the press-fitting position 111. The remaining positioning members 14 may be located at the finished product position 13 after the press-fitting process is completed or at the mounting position 15 of the workpiece 200 to be processed.

[0047] In this embodiment, three positioning members 14 may be provided on the rotary seat 12, and the three positioning members 14 are arranged in a ring array around the center of the rotary seat 12. When the workpiece 200 to be processed in one positioning member 14 is pressed into part 100 at the pressing position 111, the rotary seat 12 rotates so that the next positioning member 14 moves to the pressing position 111. At this time, the workpiece after pressing part 100 can be located at the finished product position 13 after the rotary seat 12 rotates. The workpiece at the finished product position 13 can be received as a finished product. The position of the positioning member 14 after the pressing position 111 is the mounting position 15. The mounting position 15 is used as the mounting position of the workpiece 200 to be processed, and the positioning member 14 at the mounting position 15 moves to the pressing position 111 after the rotary seat 12 rotates again. During the processing, the workpiece 200 to be processed is first placed on the positioning member 14 at the mounting position 15. Then, the rotating seat 12 rotates, causing the workpiece 200 to be processed at the mounting position 15 to move to the pressing position 111 for pressing. At this time, the workpiece 200 to be processed can continue to be installed at the mounting position 15. The rotating seat 12 rotates again, causing the workpiece (the workpiece 200 with part 100 pressed on) at the pressing position 111 to move to the finished product position 13 and can be transferred from the finished product position 13. The workpiece 200 to be processed at the mounting position 15 moves to the pressing position 111 for pressing. Through the sequential rotation of the rotating seat 12, the workpiece 200 to be processed is sequentially installed, pressed, and transferred, thereby causing the workpiece 200 to be processed to sequentially form a workpiece and be transferred and collected.

[0048] Further reference Figure 4 and Figure 5 In some specific embodiments, the positioning member 14 may be provided with a positioning groove 141. The shape of the positioning groove 141 may be adapted to the outer contour of the workpiece 200 to be processed, so that when the workpiece 200 is installed on the positioning member 14, the workpiece 200 may be completely or substantially completely fitted with the wall forming the positioning groove 141. At this time, the wall forming the positioning groove 141 can position the workpiece 200. The rotating seat 12 may be connected to a rotary drive component such as a motor, so that the rotating seat 12 may be driven to rotate. When three positioning members 14 are provided, the rotating seat 12 may rotate 120° each time, so that multiple positioning members 14 rotate sequentially. In other embodiments, the positioning member 14 may be used to hold the workpiece 200, or the positioning member 14 may also be connected to the workpiece 200 using other detachable connection structures.

[0049] Further reference Figure 3 , Figure 6 and Figure 7 The clamping unit 2 is used to clamp and fix the part 100, and the clamping unit 2 can be driven by the driving unit 3 to move toward the pressing position 111 so that the part 100 can be pressed onto the workpiece 200 to be processed on the pressing position 111. The clamping unit 2 may include a placement member 21 and a clamping member 22. The placement member 21 is used to accommodate the part 100, and the clamping member 22 fixes the part 100 accommodated in the placement member 21. Specifically, the placement member 21 is provided with a receiving cavity 212 for accommodating the part 100 and a first opening 213 and a second opening 214 communicating with the receiving cavity 212. The first opening 213 can serve as the mounting port of the part 100, that is, the part 100 can move from the outside of the first opening 213 into the receiving cavity 212. The second opening 214 allows the clamping member 22 to extend into the receiving cavity 212. When part 100 moves into the receiving cavity 212, clamping member 22 can move from the second opening 214 toward the receiving cavity 212 to fix part 100. After part 100 is pressed onto the workpiece 200, clamping member 22 can move away from the receiving cavity 212 to release part 100. Clamping member 22 can be a cylinder, and the pneumatic extension rod of the cylinder is used to extend from the second opening 214 into the receiving cavity 212 to press against part 100.

[0050] In some specific embodiments, the first opening 213 and the second opening 214 are located on adjacent sides of the storage member 21. For example, the first opening 213 is located on the rear side of the storage member 21, and the second opening 214 is located on the left or right side of the storage member 21. When the first opening 213 and the second opening 214 are located on opposite sides of the storage member 21, the first opening 213 and the second opening 214 are arranged opposite each other. At this time, the direction of movement of the clamping member 22 toward the receiving cavity 212 is toward the first opening 213. The clamping member 22 can only use the method of adding a clamping structure and directly clamping and fixing the part 100 through the clamping structure, and its clamping structure is complex. By setting the first opening 213 and the second opening 214 as adjacent sides of the object 21, and the opposite side of the second opening 214 forming the wall of the receiving cavity 212, the clamping member 22 only needs to press the part 100 against it. One end of the part 100 contacts the clamping member 22, and the other end of the part 100 contacts the wall forming the receiving cavity 212, so that the part 100 can be clamped. There is no need to set up an additional structure to clamp and fix the part 100, and the structure is simple.

[0051] After part 100 is fixed to the holder 21, the holder 21 will be driven by the drive unit 3 to move toward the pressing position 111. To ensure that part 100 inside the holder 21 remains fixed during movement, the clamping unit 2 may be provided with a first mounting plate 23 for mounting the holder 21 and the clamping member 22. The holder 21 and the clamping member 22 can be fixed to the first mounting plate 23 by screws or other fasteners and maintain a relatively fixed position. When the drive unit 3 drives any one of the first mounting plate 23, the holder 21, and the clamping member 22 to move, the first mounting plate 23, the holder 21, and the clamping member 22 will all move synchronously. Therefore, the clamping member 22 can move with the holder 21 so that the clamping member 22 can always press and fix the part 100 inside the holder 21.

[0052] The drive unit 3 can specifically abut against the object 21 in the clamping unit 2, so that the drive unit 3 drives the object 21 and the part 100 located in the object 21 to move. The drive unit 3 can specifically be a cylinder.

[0053] When the existing drive unit 3 drives the placement component 21 to move, the drive speed of the drive unit 3 is consistent, and the placement component 21 and the part 100 located in the placement component 21 are pressed into the workpiece 200 at a constant speed. Since the drive speed of the drive unit 3 is generally relatively fast, the part 100 is prone to deformation due to large instantaneous impact when pressing the part 100; furthermore, after the part 100 is pressed into place, there is no restraint on the drive unit 3, which may cause the drive unit 3 to continue to press the part 100, thereby causing the part 100 to be over-pressed and increasing the risk of deformation of the part 100.

[0054] Further reference Figure 4 , Figures 8 to 10 In this application, the drive unit 3 may be connected to a buffer unit 4. The buffer unit 4 is used to buffer the drive unit 3 during its operation to reduce or prevent the risk of over-insertion and deformation of the part 100. Specifically, the buffer unit 4 may include a fixed-position limiting plate 41, and elastic buffer members 42 and hard buffer members 43 connected to the drive unit 3. The limiting plate 41 is fixed in position and will not move in the pressing direction when the drive unit 3 drives the object 21 to move. The elastic buffer members 42 and hard buffer members 43 connected to the drive unit 3 will move synchronously when the drive unit 3 drives the object 21. For example, the drive unit 3 includes a housing and a telescopic member located inside the housing. The telescopic member may be a pneumatic telescopic rod of a cylinder. When the drive unit 3 is running, the housing remains fixed, and the telescopic member performs telescopic movement to drive the object 21 to move. The limiting plate 41 remains fixed to the housing of the drive unit 3, and the limiting plate 41 is located in front of the elastic buffer members 42 and hard buffer members 43 along the moving direction of the object 21. The elastic buffer 42 and the rigid buffer 43 are fixedly connected to the telescopic component of the drive unit 3 so that the elastic buffer 42 and the rigid buffer 43 can move synchronously with the telescopic component.

[0055] In this case, the distance between the elastic buffer 42 and the limiting plate 41 in the free state is smaller than the distance between the rigid buffer 43 and the limiting plate 41. (Refer to...) Figures 8 to 10 , Figure 8 This describes the state when the driving unit 3 starts driving the clamping unit 2. When the driving unit 3 operates, the elastic buffer 42 and the rigid buffer 43 move synchronously towards the limiting plate 41, with the elastic buffer 42 contacting the limiting plate 41 first. (Refer to...) Figure 9 , Figure 9 The state is as follows: when the elastic buffer 42 contacts the limiting plate 41, compression occurs, applying resistance to the movement of the drive unit 3. At this time, the driving speed of the drive unit 3 decreases, and the moving speeds of the object 21 and part 100 also decrease. Furthermore, as the drive unit 3 moves further, the elastic potential energy of the elastic buffer 42 increases with the degree of compression, increasing the resistance applied to the drive unit 3 and gradually reducing its driving speed. Therefore, when part 100 is pressed onto the workpiece 200, part 100 will not experience violent impact, effectively reducing the risk of deformation due to large instantaneous impact. Moreover, during the process of part 100 not being press-fitted into place, continuous elastic buffering with a continuously increasing buffering force further effectively reduces the risk of deformation. (Refer to...) Figure 10 , Figure 10This is the state when the rigid buffer 43 contacts the limiting plate 41. When the part 100 is pressed into place, the rigid buffer 43 contacts the limiting plate 41 and forms a hard contact with the limiting plate 41, thereby restricting the further movement of the drive unit 3. At this time, the drive unit 3 stops due to the restriction of the rigid buffer 43 to prevent the part 100 from being pressed into the wrong position and to ensure the pressing accuracy of the part 100.

[0056] The drive unit 3 is initially restricted by the elastic buffer 42 to reduce its driving speed. This reduces the pressing speed when part 100 is pressed into workpiece 200, effectively lowering the risk of part 100 deformation. Furthermore, the elastic buffer 42 allows the drive unit 3 to maintain a faster driving speed and ensure pressing force when it begins to move the workpiece 21, reducing pressing time. The driving speed decreases when the elastic buffer 42 contacts the limiting member, at which point part 100 is about to be pressed into workpiece 200 or has just come into contact with it, further reducing pressing time and the risk of part 100 deformation. A rigid buffer 43 positions part 100 in the pressing position. Once part 100 is pressed into place, the rigid buffer 43 makes hard contact with the limiting plate 41, stopping the drive unit 3 and providing a secondary restriction to prevent over-pressing of part 100.

[0057] Further reference Figures 8 to 10 In some specific embodiments, the elastic buffer 42 includes a telescopic rod 421 and an elastic element 422 sleeved on the telescopic rod 421. The telescopic rod 421 includes a head with a larger diameter and a rod with a smaller diameter. The elastic element 422 is sleeved on the rod of the telescopic rod 421, and one end abuts against the head of the telescopic rod 421. When the elastic buffer 42 contacts the limiting plate 41, the head of the telescopic rod 421 first contacts the limiting plate 41 and retracts. At this time, the head of the telescopic rod 421 presses against the elastic element 422 to apply resistance to the movement of the drive unit 3. The rigid buffer 43 can be made of a rigid material and can directly contact the limiting plate 41. For example, the rigid buffer 43 can be a hard metal or a hard plastic, and the limiting plate 41 can also be a hard metal or a hard plastic.

[0058] Further reference Figure 11In some specific embodiments, the buffer unit 4 may further include a third buffer 44. The third buffer 44 can be used to restrict the movement of the drive unit 3 to cooperate with the rigid buffer 43 and the elastic buffer 42 to form multiple protections. The third buffer 44 can be installed in the clamping unit 2 and connected to the drive unit 3. For example, the third buffer 44 can be installed in the placement member 21 of the clamping unit 2. Specifically, the placement member 21 may be provided with a through cavity 211, and the third buffer 44 is disposed in the through cavity 211. When the placement member 21 moves toward the workpiece 200, the workpiece 200 can pass through the receiving cavity 212 of the placement member 21 and extend into the through cavity 211 to abut against the third buffer 44. By controlling the installation position 15 of the third buffer 44, when the part 100 is pressed into place, the third buffer 44 abuts against the workpiece 200 and forms a hard contact. The third buffer 44 can abut against the drive unit 3, and the third buffer 44 is located between the drive unit 3 and the workpiece 200. When the third buffer 44 makes hard contact with the workpiece 200, it will also make hard contact with the drive unit 3 to limit further movement of the drive unit 3 and prevent the part 100 from being pressed into the wrong position. The shaft end of the workpiece 200 passes through the receiving cavity 212 of the placement member 21 and extends into the through cavity 211 to abut against the third buffer 44, so that the third buffer 44 makes hard contact with the workpiece 200.

[0059] The feeding unit 5 is used to move the part 100 from the first opening 213 of the object 21 into the receiving cavity 212 of the object 21. The feeding unit 5 may include a part support 51 and a feeding drive 52 for driving the part support 51 to move. The part support 51 can be used to place the part 100. The feeding drive 52 is used to drive the part support 51 toward the receiving cavity 212, so that the part of the part support 51 used to support the part 100 can move from the first opening 213 into the receiving cavity 212. After the clamping member 22 fixes the part 100 in the receiving cavity 212, the feeding drive 52 can drive the part support 51 to move out of the receiving cavity 212. Specifically, the feeding drive 52 can be a cylinder.

[0060] In some specific embodiments, the feeding unit 5 may further include a guide block 53, which is provided with a guide groove 531 extending along the moving direction of the part support 51 and a loading groove 532 communicating with the guide groove 531. The part 100 support can move within the guide groove 531, and the part 100 support can initially be positioned below the loading groove 532, and the part 100 support can receive the part 100 provided by the feeding unit 6 through the loading groove 532. Subsequently, the part support 51 is driven by the feeding drive 52 to move the part 100 into the receiving cavity 212 of the placement member 21.

[0061] Further reference Figure 12 The feeding unit 6 may include a dispensing component 61 and a transfer component 62. The dispensing component 61 is used to dispense loose parts 100 so that the parts 100 are arranged sequentially, and the dispensing component 61 is used to move the parts 100 toward the feeding unit 5. The transfer component 62 is installed on the side of the dispensing component 61 adjacent to the feeding unit 5, and the transfer component 62 is used to move the parts 100 from the dispensing component 61 to the part support 51 located below the loading trough 532. The transfer component 62 may be connected to a driving component such as a cylinder. After picking up the parts 100 from the dispensing component 61, the transfer component 62 is driven by the driving component such as the cylinder to move horizontally above the loading trough 532, and places the parts 100 on the part support 51 located below the loading trough 532. The transfer component 62 can pick up the parts 100 by clamping, vacuum adsorption, or other methods. One or more transfer components 62 may be provided.

[0062] The material distribution assembly 61 may include a vibratory feeder 611 and a storage belt 612 connected to the vibratory feeder 611. The vibratory feeder 611 generates vibration to distribute the loose parts 100. After passing through the vibratory feeder 611, the parts 100 are arranged sequentially on the storage belt 612. The storage belt 612 extends from the vibratory feeder 611 to the feeding unit 5. The storage belt 612 receives the parts 100 distributed by the vibratory feeder 611 and conveys the parts 100 toward the feeding unit 5. The storage belt 612 may be a stepping conveyor belt.

[0063] Further reference Figure 1 and Figure 2 The transfer unit 7 reciprocates between the pressing station 1 and the unloading unit 8 to transfer the workpieces that have been pressed in the pressing station 1 to the unloading unit 8 for unloading. Specifically, the unloading unit 8 includes an unloading position 81 and a carrier 82 located at the unloading position 81, and the carrier 82 is provided with multiple receiving slots 821. When the workpiece of the pressed part 100 moves to the finished product position 13 of the pressing station 1, the transfer unit 7 is used to grip and move the workpiece located at the finished product position 13 into the receiving slots 821 of the carrier 82. The transfer unit 7 can specifically be a four-axis robot.

[0064] To facilitate continuous operation, multiple carriers 82 can be provided, and each carrier 82 can be connected to a transfer component 83. The transfer component 83 can transport a carrier 82 to the unloading position 81. When the carrier at the unloading position 81 is full of workpieces, the transfer component 83 can drive the full carrier 82 out of the unloading position 81 and transfer the empty carrier 82 to the unloading position 81, so that the unloading unit 8 can continuously receive workpieces. The full carrier 82 can be removed by personnel and transported to the next process via transfer equipment such as AGV carts. The transfer component 83 can use a common existing drive system, which will not be described in detail here.

[0065] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
