Description

Technical Field

[0001] This invention relates to the field of equipment component assembly technology, specifically a gasket and gear assembly machine. Background Technology

[0002] As is generally known, a planetary gear set is a composite gear system consisting of multiple planetary gears, a sun gear, an internal gear ring, and a planetary carrier. It is typically used for transmission and speed change. When the planetary gear set is working, the sun gear drives the planetary gears, and the planetary gears simultaneously mesh with the internal gear ring. Depending on the input and output connection method, the output speed and torque can be changed.

[0003] When assembling a planetary gear set, multiple planetary gears need to be mounted on a planetary carrier. This requires installing shims at both axial ends of each planetary gear. For example, patent CN119238068A, published on January 3, 2025, entitled "An Automated Planetary Gear Installation Device," includes: an installation station for mounting a planetary carrier, the planetary carrier being rotatably positioned at the installation station; a feeding module for feeding planetary gears into a window of the planetary carrier, including a feeding track and a feeding frame moving along the feeding track; and a material loading module, including a gear loading module and a shim loading module, for loading planetary gears and shims onto the feeding frame, respectively. The automated installation equipment provided by this invention, through the cooperation between the installation station, the feeding module, and multiple loading modules, enables the sequential configuration and assembly of various components of the planetary gear transmission structure without human intervention. By replacing human labor with machines, the positioning accuracy between the components and the stability during assembly are greatly improved, thereby increasing the yield and efficiency of the planetary gear transmission structure assembly work, effectively controlling labor costs, and facilitating production management.

[0004] The shortcoming of the above-mentioned prior art is that the installation of planetary gears, planet carriers and shims requires multiple loading operations, and the operation is carried out at one station. Obviously, this operation method will have an adverse effect on the assembly efficiency of planetary gear sets. Summary of the Invention

[0005] The purpose of this invention is to provide a gasket and gear assembly machine to solve the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A gasket and gear assembly machine includes a frame assembly with mounting bases for placing a planetary carrier, a gasket feeding mechanism, and a gear feeding mechanism arranged on the frame assembly. It also includes a conveyor line assembly with a first installation station and a second installation station arranged sequentially along its conveying direction. Several mounting bases are arranged on the conveyor line assembly. The gasket feeding mechanism includes a lower module for feeding lower gaskets and an upper module for feeding upper gaskets. The lower module is located at the first installation station. During operation, the lower module installs the lower gasket at a designated position on the planetary carrier. The upper module and the gear feeding module are arranged together at the second installation station. During operation: in the first stroke, the upper module installs the upper gasket on the planetary gear; in the second stroke, the gear feeding module installs the planetary gear at the position of the lower gasket on the planetary carrier.

[0008] As described above, the planetary gear consists of a gear, a cage, and a needle roller bearing, and the equipment frame assembly is provided with a detection mechanism for detecting the planetary gear assembly.

[0009] Each of the aforementioned mounting bases is provided with several material feeding grooves for placing the lower and upper gaskets.

[0010] The arrangement of the lower shim in the corresponding feed slot is the same as its arrangement when it is installed on the planetary carrier; the arrangement of the upper shim in the corresponding feed slot is the same as its arrangement when it is installed on the planetary gear.

[0011] As mentioned above, each of the feeding troughs is equipped with a first combing mechanism. Based on the combing action of the first combing mechanism, multiple lower pads are arranged axially spaced in the corresponding feeding troughs.

[0012] The first combing mechanism mentioned above includes two belt drive mechanisms arranged radially in the feeding trough. Each belt drive mechanism has a plurality of combing blocks arranged sequentially along the conveying track on its conveyor belt. The plurality of combing blocks on the two belt drive mechanisms correspond one-to-one. The space between two combing blocks at adjacent positions along the conveying direction is used to place the lower pad.

[0013] As described above, each of the belt drive mechanisms is also provided with a one-way drive mechanism; when the lower pad is placed into the feeding trough, the one-way drive mechanism releases the restriction on the belt drive mechanism; when the lower module picks up the lower pad from the feeding trough, based on the restriction of the one-way drive mechanism, the belt drive mechanism transports the lower pad in the direction away from the feeding trough.

[0014] As described above, the lower module includes a drive mechanism and a gripping mechanism located at the power output end of the drive mechanism. The gripping mechanism includes a gripping arm, and two clamping blocks are slidably provided on the gripping arm along a certain radial direction of the lower pad. Under the driving force of the drive mechanism, the two clamping blocks clamp the inner ring of the lower pad in a way that they are far apart.

[0015] As described above, the two clamping blocks are provided with clamping grooves in contact with the clamped lower pad, and the outer shape of the clamping grooves matches the inner ring outer shape of the lower pad.

[0016] As described above, each of the clamping blocks is provided with a second combing mechanism. The two clamping blocks can grab a number of lower pads corresponding to the number of lower pads that need to be installed on each planetary carrier at one time. Based on the combing action of the second combing mechanism, the two lower pads at adjacent positions are arranged at intervals.

[0017] The beneficial effects of the present invention are as follows: by arranging a first installation station and a second installation station on the conveyor assembly, in the conveying direction of the conveyor assembly, when the second installation station sequentially assembles the upper shim and planetary gear, and the planetary gear and planetary carrier, the first installation station installs the lower shim on the next planetary carrier. Obviously, the dual-station operation can better improve the assembly efficiency of the planetary gear set compared with the single-station operation. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 11 The present invention will now be described in further detail.

[0033] This invention provides a gasket and gear assembly machine, including a frame assembly 1. The frame assembly 1 has an mounting base 2 for placing a planetary carrier 9, a gasket feeding mechanism 3, and a gear feeding mechanism 4 arranged on it. It also includes a conveyor line assembly 5, with a first installation station and a second installation station arranged sequentially in its conveying direction. Several mounting bases 2 are arranged on the conveyor line assembly 5. The gasket feeding mechanism 3 includes a lower module for feeding lower gaskets 7 and an upper module for feeding upper gaskets 6. The lower module is located at the first installation station. During operation, the lower module installs the lower gasket 7 at a designated position on the planetary carrier 9. The upper module and the gear feeding module are arranged together at the second installation station. During operation: in the first stroke, the upper module installs the upper gasket 6 onto the planetary gear 8; in the second stroke, the gear feeding module installs the planetary gear 8 onto the position of the lower gasket 7 on the planetary carrier 9.

[0034] Specifically, during the assembly of planetary gear set 8, the shims and planetary gear 8 need to be installed on the planet carrier 9 first, and then the rotating shaft in the middle of planetary gear 8 needs to be installed. For ease of description and understanding, the planetary gear 8 is installed on the planet carrier 9 with its axial direction parallel to the vertical direction. The shim at the lower end of the planetary gear 8's axial direction is called the lower shim 7, and the shim at the upper end of its axial direction is called the upper shim 6. The upper shim 6 and the lower shim 7 have the same structure and are symmetrically arranged at both ends of the planetary gear 8's axial direction. During the assembly process, the planet carrier 9 is first placed on the mounting base 2. The mounting base 2 is a plate-like structure, on which a clamping mechanism for holding the planet carrier 9 and a mechanism for driving the planet carrier 9 around its circumference are arranged. The intermittently rotating mechanism, which is existing technology and will not be described in detail, involves the following assembly process: the shim feeding mechanism 3 first places the lower shim 7 sequentially along the circumference on the planetary carrier 9 at designated positions, then places the upper shim 6 on the axial upper end of the planetary gear 8, and then places the planetary gear 8 and the upper shim 6 together on the planetary carrier 9 at positions corresponding to the lower shim 7. This completes the assembly of the shims, planetary gear 8, and planetary carrier 9. However, the drawback is that the installation of the planetary gear 8, planetary carrier 9, and shims requires multiple feeding operations, all performed at one workstation. Obviously, this operation method will have an adverse effect on the assembly efficiency of the planetary gear 8 assembly.

[0035] Based on the above problems, in this embodiment, a conveyor assembly 5 (i.e., a conveying mechanism) is provided on the equipment frame assembly 1. Several mounting bases 2 are arranged in the conveying direction of the conveyor assembly 5, and a first mounting station and a second mounting station are arranged in the conveying direction. The gasket feeding mechanism 3 is divided into a lower module for feeding the lower gasket 7 and an upper module for feeding the upper gasket 6. The lower module is arranged at the first mounting station, and the upper module and the gear feeding module are arranged together at the second mounting station.

[0036] During assembly, planetary gears 8, planetary carriers 9, upper shims 6, and lower shims 7 are manually replenished. The lower module includes a part for placing the lower shims 7 and a part for gripping each lower shim 7. The upper module includes a part for placing the upper shims 6 and a part for gripping each upper shim 6. The gear loading module includes a part for placing the planetary gears 8 and a part for gripping each planetary gear 8. At the start of the assembly, the first planetary carrier 9 is placed on the first mounting base 2 along the conveyor line assembly 5. At this time, the first mounting base 2 is in the first installation position. The mounting base 2 is equipped with a lifting mechanism and an intermittent rotation mechanism. The intermittent rotation mechanism rotates the planetary carrier 9 90 degrees each time. That is, the lower module will first grip one lower shim 7 and send it to the designated position on the planetary carrier 9. The intermittent rotation mechanism will then rotate the planetary carrier 9 90 degrees, and the lower module will then send the second lower shim 7 to the designated position on the planetary carrier 9. This process continues until all the lower shims 7 that need to be installed on the planetary carrier 9 are rotated a corresponding number of times by the intermittent rotation mechanism until all the lower shims 7 need to be installed on the planetary carrier 9 are rotated. The lower shims 7 are installed at all the positions where they are to be installed. Then, the conveyor assembly 5 transports the first mounting base 2 to the second mounting station, and the second mounting base 2 moves to the first mounting station. Subsequently, the gear feeding module places a planetary gear 8 on the mounting base 2. The upper module picks up the first upper shim 6 and installs it on the upper axial end of the planetary gear 8. Then, the gear feeding module pushes the planetary gear 8 and the upper shim 6 together into the planetary carrier 9 at the positions corresponding to each lower shim 7. After all the positions where the lower shims 7 are installed have planetary gears 8 installed, the conveyor assembly 5 transports the first mounting base 2 to the mounting shaft position, and the second mounting base 2 reaches the second mounting station. The third mounting base 2 reaches the first mounting station. The specific installation process is the same as described above. When the last mounting base 2 is in the shaft mounting position and the planetary gear 8 group has been assembled, the conveyor assembly 5 will drive all the mounting bases 2 back to the initial position. Then, following the above work process, the assembly operation of the next batch of planetary gear 8 groups will continue.

[0037] The beneficial effect of this embodiment is that by arranging a first installation station and a second installation station on the conveyor assembly 5, in the conveying direction of the conveyor assembly 5, when the second installation station sequentially assembles the upper shim 6 and the planetary gear 8, and the planetary gear 8 and the planet carrier 9, the first installation station installs the lower shim 7 on the next planet carrier 9. Obviously, the dual-station operation can better improve the assembly efficiency of the planetary gear 8 group compared with the single-station operation.

[0038] Preferably, the planetary gear 8 is composed of gears, a cage, and needle roller bearings. The equipment frame assembly 1 is provided with a detection mechanism for detecting the composition of the planetary gear 8. Specifically, to avoid defective products during the assembly of the planetary gear 8, this embodiment arranges a detection mechanism on the equipment frame assembly 1, which can detect whether any components of the planetary gear 8 are missing. If no components are missing, the material is fed normally. If there are missing components, the waste material is processed into a waste trough. An alarm will be triggered when the waste trough is full. The waste material in the waste trough is then manually cleaned. The detection mechanism can use a smart camera or a multi-point detection switch to identify the height of any position within the area, thereby ensuring that no planetary gear 8 with missing components is assembled onto the planet carrier 9.

[0039] Preferably, each of the installation bases 2 is provided with a plurality of material troughs 20 for placing lower shims 7 and upper shims 6; specifically, in order to facilitate each material loading, this embodiment provides a plurality of material troughs 20 on each installation base 2, and each material trough 20 is used to place a plurality of upper shims 6 or lower shims 7 separately. When the upper shims 6 or lower shims 7 in the material trough 20 are used up, they are manually replenished.

[0040] Since both the upper gasket 6 and the lower gasket 7 need to be positioned according to requirements during assembly, in the optional embodiment, the placement of the lower gasket 7 in the corresponding feed groove 20 is consistent with its placement when mounted on the planetary carrier 9; the placement of the upper gasket 6 in the corresponding feed groove 20 is consistent with its placement when mounted on the planetary gear 8. Therefore, the internal shape of the feed groove 20 is adapted to the outer ring shape of the lower gasket 7 or the upper gasket 6 placed therein. That is, the upper gasket 6 and the lower gasket 7 designed in this embodiment have the same structure and both have ears for anti-rotation and limiting, that is, a section will extend out from the outer ring edge of the gasket, and the end of the extended part away from the gasket body has a certain angle of bending structure (the specific extension length and bending angle are set according to the actual situation, and will not be described in detail here).

[0041] For ease of description and understanding, subsequent embodiments will use the lower pad 7 as an example, meaning the upper and lower modules have the same structure. As can be seen from the foregoing embodiments, due to the structural characteristics of the lower pad 7, when multiple lower pads 7 are placed in the same feeding slot 20, adjacent lower pads 7 will not be completely fitted together, and there will be a certain angle of contact between them. Thus, when the lower module picks up the lower pad 7, the lower pad 7 is not corrected in position. As a result, when it is assembled onto the planetary carrier 9, the lower pad 7 may be misplaced. Therefore, in a further embodiment, each feeding slot 20 is provided with a first combing mechanism. Based on the combing action of the first combing mechanism, multiple lower pads 7 are arranged axially separated in the corresponding feeding slot 20, that is, adjacent two pads are arranged separately, and the radial direction of each pad is kept parallel to the radial direction of the corresponding feeding slot 20. In this way, the lower pad 7 picked up by the lower module is also kept parallel to the horizontal plane in radial direction, which can effectively reduce the misplacement of the lower pad 7 when it is placed onto the planetary carrier 9.

[0042] Preferably, the first combing mechanism includes two belt drive mechanisms arranged radially within the feeding trough 20. Each belt drive mechanism has a plurality of combing blocks 21 arranged sequentially along the conveying track on its conveyor belt. The plurality of combing blocks 21 on the two belt drive mechanisms correspond one-to-one. The space between two combing blocks 21 at adjacent positions along the conveying direction is used to place the lower pad 7.

[0043] Specifically, each belt drive mechanism includes a drive belt and two pulleys. The specific working principle is existing technology and will not be elaborated here. In this embodiment, based on the belt drive mechanism, multiple combing blocks 21 are arranged sequentially along the track of the drive belt. Several combing blocks 21 on two belt drive mechanisms correspond one-to-one. The space between two combing blocks 21 at adjacent positions along the conveying direction is used to place the lower pads 7. This space is named the discharge cavity. When several lower pads 7 are placed in the discharge groove 20, along the depth direction of the discharge groove 20 (parallel to its own axis away from the opening end), after placing a lower pad 7 in the uppermost discharge cavity, it will move down one unit distance. The size of this unit distance is the thickness size of a lower pad 7. At this time, another discharge cavity will be formed at the top. This continues to place lower pads 7 until no more can be placed. When the lower module grabs the lower pads 7, it also grabs them sequentially from top to bottom.

[0044] As the number of lower pads 7 gripped increases, the depth of the lower module extending into the discharge trough 20 also increases. Therefore, in an optional embodiment, each belt drive mechanism is also equipped with a one-way drive mechanism. When a lower pad 7 is placed into the discharge trough 20, the one-way drive mechanism releases the restriction on the belt drive mechanism, that is, at this time, the two belt drive mechanisms cooperate to extend the lower pad 7 into the discharge trough 20. When the lower module grips the lower pad 7 from the discharge trough 20, based on the restriction of the one-way drive mechanism, the belt drive mechanism transports the lower pad 7 in the direction away from the discharge trough 20, that is, at this time, the lower module grips... When the previous lower pad 7 needs to leave the feeding trough 20, the lower pad 7 will drive the two belt transmission mechanisms to move. At this time, the two belt transmission mechanisms are equivalent to conveying the lower pad 7 outward. However, after the lower module grabs the previous lower pad 7 and leaves the feeding trough 20, based on the gravity of the remaining lower pads 7 and under the restriction of the one-way transmission mechanism, the two belt transmission mechanisms will not extend into the feeding trough 20 to convey the lower pads 7. Among them, the one-way transmission mechanism, such as the ratchet and pawl mechanism, only needs to release the restriction of the ratchet on the ratchet when loading the lower pad 7 into the feeding trough 20. This is the existing technology and will not be elaborated on further.

[0045] Preferably, the lower module includes a drive mechanism and a gripping mechanism located at the power output end of the drive mechanism. The gripping mechanism includes a gripping arm 30, and two clamping blocks 31 are slidably provided on the gripping arm 30 along a certain radial direction of the lower pad 7. Under the driving force of the drive mechanism, the two clamping blocks 31 clamp the inner ring of the lower pad 7 in a way that they are far apart.

[0046] Specifically, the planetary carrier 9 has a flange structure at the bottom along the axial direction and a horizontally arranged plate structure at the top, with holes for mounting the planetary gear 8 shafts. The flange structure also has corresponding holes for each shaft. The plate structures on both sides of each planetary gear 8 mounting position are connected to the flange structure by vertically arranged plate structures. Therefore, when assembling the lower gasket 7 and the planetary gear 8, it can only enter and exit from the radial side. Thus, in this embodiment, the drive mechanism needs to enable the gripping mechanism to move linearly in multiple directions and also needs to drive the two clamping blocks 31 to move away from each other and clamp the lower gasket 7 from the inner ring. The drive mechanism can be composed of multiple drive sources that can achieve linear movement, such as multiple cylinders arranged in multiple directions. Clamping the lower gasket 7 from the inner ring is because the lower gasket 7 is installed at the corresponding position on the planetary carrier 9. When the lower gasket 7 is in the middle, the outer ring is blocked. Using inner ring and outer support clamping can better deliver the lower gasket 7 into place.

[0047] Preferably, the two clamping blocks 31 are provided with clamping grooves 32 in contact with the clamped lower pad 7. The outer shape of the clamping grooves 32 matches the inner ring outer shape of the lower pad 7. Specifically, since the lower pad 7 is relatively thin, it may rotate or fall off when clamped by the two clamping blocks 31. Therefore, in this embodiment, clamping grooves 32 are provided on each clamping block 31. In this way, when the lower pad 7 is clamped by the two clamping blocks 31, the risk of the lower pad 7 falling off can be effectively solved because there is a height difference between the part of the clamping groove 32 in contact with the inner ring of the lower pad 7 and the rest of the clamping block 31. Moreover, the outer shape of the clamping groove 32 is adapted to the inner ring outer shape of the lower pad 7, so it is difficult for the lower pad 7 to rotate relative to the contact surface of the clamping groove 32, thereby better clamping each lower pad 7.

[0048] Furthermore, each of the clamping blocks 31 is provided with a second combing mechanism. The two clamping blocks 31 can grab a number of lower pads 7 corresponding to the number of lower pads 7 that need to be installed on each planetary carrier 9 at one time. Based on the combing action of the second combing mechanism, the two lower pads 7 at adjacent positions are arranged at intervals.

[0049] The second combing mechanism includes a belt drive mechanism (with the same structure as the belt drive mechanism in the aforementioned embodiment) arranged on each clamping block 31. Multiple gripping blocks 33 are sequentially arranged along the conveying track on the conveyor belt of the belt drive mechanism. The distance between two adjacent gripping blocks 33 is the same as the thickness of a lower pad 7. The multiple gripping blocks 33 on the two clamping blocks 31 correspond one-to-one. Thus, the two belt drive mechanisms work together, and the two clamping blocks 31 can grip the corresponding number of lower pads 7 that need to be installed on each planetary carrier 9 at one time. For example, if each planetary carrier 9 requires four lower pads 7, then the two clamping blocks 31 can grip each lower pad 7 at one time. The device can grasp four or more lower pads 7 at a time. Each belt drive mechanism has a pulley with a fixed drive wheel 34. The two drive wheels 34 are symmetrically arranged. The drive mechanism includes a drive source for driving the relative movement of the two clamping blocks. A first pressing rod 35 is mounted on the power output end of this drive source. The first pressing rod 35 is slidably mounted on the gripping arm 30, which is slidably positioned on the power output end of the drive source in the drive mechanism area. Each clamping block 31 has a pressure surface 36. The first pressing rod 35 and each pressure surface 36 are wedge-shaped to form a pressing action. The two clamping blocks 31... An elastic element 37 is provided between the two clamping blocks 31. Based on the elastic force of the elastic element 37, the two clamping blocks 31 tend to move away from each other to achieve outward expansion and external support clamping of the lower pad 7. Each clamping block 31 has a guide groove 38, and a guide block 39 is slidably provided in the guide groove 38. The guide block 39 is fixed to the clamping arm to ensure the stability of the relative movement of the two clamping blocks 31. When the first extrusion rod 35 extrudes the two pressure surfaces 36, the two clamping blocks 31 move closer to each other and release the clamping of the lowermost lower pad 7. The lower pad 7 falls into the designated position on the planetary carrier 9. During the process of the first extrusion rod 35 extruding the two pressure surfaces 36... Since the elastic force of the elastic element 37 will prevent the first extrusion rod 35 from extruding the two pressure surfaces 36, in the initial stage, after the first extrusion rod 35 contacts the two pressure surfaces 36, based on the elastic force of the elastic element 37, the first extrusion rod 35 will first drive the clamping arm to move and drive the two clamping blocks 31 into the planetary carrier 9. When the movement of the clamping arm is restricted, the first extrusion rod 35 will continue to move and extrude the two pressure surfaces 36. Conversely, when the first extrusion rod 35 moves away from the two pressure surfaces 36, under the action of the rebound force of the elastic element 37, the first extrusion rod 35 will first disengage from the two pressure surfaces 36, and then drive the clamping arm to be pulled away from the planetary carrier 9.

[0050] Each drive wheel 34 has multiple first grooves 340, multiple second grooves 341, and one third groove 342 on its surface. The length direction of the first groove 340 is parallel to the axial direction of the drive wheel 34. The second groove 341 has a columnar spiral structure on the surface of the drive wheel 34. The multiple first grooves 340 and multiple second grooves 341 are arranged alternately in the circumferential direction of the drive wheel 34. The first extrusion rod 35 is provided with a second extrusion rod 343. The second extrusion rod 343 has an elastic telescopic structure and can slide within the first grooves 340, second grooves 341, and third grooves 342. For ease of description and understanding, the direction in which the first extrusion rod 35 extrudes the pressure-bearing surface 36 is taken as the reference direction. Along this direction, the first groove 340 sequentially includes end a. The second groove 341 includes ends c and d. Taking one of the drive wheels 34 as an example, when the lowest lower pad 7 needs to be placed in a designated position on the planetary carrier 9, the drive wheel 34 needs to rotate counterclockwise. That is, end b of the first groove 340 is connected to end d of the second groove 341, which is adjacent in the counterclockwise direction, and end a of the first groove 340 is connected to end c of the second groove 341, which is adjacent in the clockwise direction. In the direction of movement when the first extrusion rod 35 extrudes the pressure surface 36, the second extrusion rod 343 will directly enter end c of the second groove 341, which is adjacent in the clockwise direction, from end a of the first groove 340 (that is, the depth of end a is the same as the depth of end c, while the depth of the rest of the first groove 340 is less than...). The second extrusion rod 343 moves from the d end of the second groove 341 to the b end of the adjacent clockwise first groove 340. During this process, the second extrusion rod 343 exerts a pressing effect on the side wall of the second groove 341, causing the power wheel 34 to rotate once in the clockwise direction. Each rotation will drive the belt drive mechanism to move once, causing the lower pad 7 at the lowest position to fall into the designated position of the planetary carrier 9. As the first extrusion rod 35 moves away from the pressure surface 36, the second extrusion rod 343 moves from the b end of the first groove 340 where it is located to the a end (that is, the depth of the b end is greater than the depth of the d end). To prevent the power wheel 34 from rotating when the first extrusion rod 35 presses the two pressure surfaces 36, the second extrusion rod 343 moves from the b end of the first groove 340 to the a end (that is, the depth of the b end is greater than the depth of the d end). The b-end of the first groove 340 extends outwards, meaning the first pressing rod 35 drives the second pressing rod 343 directly from the a-end of the first groove 340 into the c-end of the adjacent clockwise second groove 341, and then from the d-end of the second groove 341 into the b-end of another adjacent clockwise first groove 340. It then continues to move along the length of the first groove 340. At this point, the second pressing rod 343 has no circumferential pressing action with the first groove 340, so the power wheel 34 will not rotate. The first pressing rod 35 presses the two pressure surfaces 36, causing the two clamping blocks 31 to move closer together, dropping the lowermost pad 7 into the designated position on the planetary carrier 9. To prevent the remaining lower pads 7 from falling from their positions...The furthest distance between the two corresponding gripping blocks 33 of the two belt drive mechanisms is still greater than the furthest distance between the clamped positions of the lower pads 7. To facilitate the subsequent loading of the lower pads 7 onto the two clamping blocks 31, this embodiment provides a third groove 342 at end a of the first groove 340. The third groove 342 has an annular structure, and its depth is less than the depth of the first groove 340. (During the circumferential sliding of the second extrusion rod 343 along the third groove 342, each time it reaches a position of the first groove 340, the first groove 340 will obstruct the continued movement of the second extrusion rod 343. This method can be used to measure the number of lower pads 7 loaded each time, and can also prevent the belt drive mechanism from rotating due to weight changes in the loaded lower pads 7.) That is, when loading from the discharge trough 20, the two clamping blocks 31 will... The second pressing rod 343 is inserted into the discharge trough 20. At this time, the two belt drive mechanisms within the discharge trough 20 are restricted by a one-way transmission mechanism. As the two clamping blocks 31 enter the discharge trough 20, the two belt drive mechanisms on the clamping blocks 31 rotate due to the obstruction of the lower pads 7, rotating once after each lower pad 7. During the withdrawal of the two clamping blocks 31 from the discharge trough 20, the two belt drive mechanisms within the discharge trough 20 can rotate under external force, while the second pressing rod 343 returns from the third slide 342 to the corresponding first slide 340. The rotation of the power wheel 34 is then restricted. Therefore, during the process of the two clamping blocks 31 pulling out the lower pads 7, the two belt drive mechanisms within the discharge trough 20 are not restricted by the one-way rotation mechanism, allowing the lower pads 7 to be loaded smoothly.

[0051] The advantages of this setup are: firstly, it reduces the number of times the lower pad 7 is loaded, thereby reducing the travel of the clamping arm and improving the assembly efficiency of the lower pad 7; secondly, by arranging the loaded lower pads 7 separately, the lowermost lower pad 7 is placed at a designated position on the planetary carrier 9 each time, and the remaining lower pads 7 will not fall, thus avoiding affecting the assembly operation.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
