Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated assembly equipment technology, specifically to an automatic planetary gear assembly mechanism. Background Technology
[0002] Currently, most automotive electronic parking brake (electronic handbrake) actuators on the market contain a planetary reduction mechanism, which works with a motor to achieve high torque output and enable the electronic parking function. Installing the planetary gear set in this actuator is relatively difficult. Because the planetary gear set has four planetary gears, and the actuator housing mounting position has internal teeth (which mesh with the planetary gears), the small clearance during installation makes it easy for the planetary gears to interfere with the internal teeth of the housing. Therefore, during assembly, the planetary gear assembly needs to be rotated while being moved downwards into the actuator housing. This makes manual assembly difficult and inefficient, and it is also difficult to guarantee the consistency of the assembled product. Utility Model Content
[0003] This utility model addresses the technical problems existing in the prior art by providing an automatic planetary gear assembly mechanism to solve the problem of labeling pipe fittings.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An automatic planetary gear assembly mechanism includes a feeding component, a tray, a lifting component, and a positioning component. An actuator housing and a planetary gear assembly are placed on the tray. The feeding component is used to transport the tray to the installation position. The lifting component includes a rotating rod, a lifting bracket, a lifting drive, a rotation drive, and an installation drive. The rotating rod passes through the lifting bracket. The lifting drive is used to drive the lifting bracket to lift the tray located at the installation position. The rotation drive is used to drive the rotating rod to rotate. The installation drive is used to drive the rotating rod to move along its axial direction. The positioning component includes a positioning bracket, a positioning gripper, a positioning drive, a pressure shaft, a pressure cover, and an elastic element. The positioning bracket is disposed at the installation position. The positioning gripper is disposed on the positioning bracket and is used to clamp the actuator housing. The elastic element is disposed between the pressure shaft and the pressure cover. The positioning drive is used to drive the pressure shaft to move towards or away from the tray.
[0005] Furthermore, the feeding assembly includes a conveyor track and a conveyor belt, the conveyor belt being disposed on the conveyor track, and the pallet being placed on the conveyor belt.
[0006] Furthermore, the feeding assembly also includes a positioning element, which is disposed at the mounting position to prevent the pallet from moving.
[0007] Furthermore, the lifting bracket includes a mounting plate and a lifting plate. The mounting plate is fixed to the mounting position and located below the tray. The lifting plate is connected to the mounting plate through the lifting drive component and is located between the mounting plate and the tray.
[0008] Furthermore, the lifting support plate is provided with a positioning pin, which is used to position the pallet.
[0009] Furthermore, the mounting drive includes a servo motor, a linear module, a rotary drive, and a mounting bracket. The mounting bracket is connected to the linear module, and the servo motor is driven by the linear module to drive the mounting bracket to move on the linear module. The rotary drive is connected to the mounting bracket, and its output end is connected to the rotating rod.
[0010] Furthermore, both the mounting plate and the lifting plate are provided with through and concentric through holes. A linear bearing is provided in the through hole of the lifting plate. The rotating rod passes through the through hole of the mounting plate and is inserted into the linear bearing.
[0011] Furthermore, the positioning component also includes a gripper cylinder, which is used to drive the positioning gripper to grip or release the actuator housing.
[0012] Furthermore, the pressure cap is slidably connected to the pressure shaft, and the elastic element is sleeved on the pressure shaft and located between the pressure cap and the pressure shaft.
[0013] Furthermore, the positioning drive component is a pneumatic slide.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0025] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed structures. Those skilled in the art can understand the specific meaning of these terms in this patent based on the specific circumstances.
[0026] like Figures 1-5 As shown, the present invention provides an automatic planetary gear assembly mechanism, including a feeding component 1, a tray 2, a lifting component 3 and a positioning component 4. The actuator housing and the planetary gear assembly are placed on the tray 2, and the feeding component 1 is used to transport the tray 2 to the installation position.
[0027] The lifting assembly 3 includes a rotating rod 31, a lifting bracket 32, a lifting drive 33, a rotation drive 34, and a mounting drive 35. The rotating rod 31 passes through the lifting bracket 32. The lifting drive 33 is used to drive the lifting bracket 32 to lift the tray 2 located in the mounting position. The rotation drive 34 is used to drive the rotating rod 31 to rotate. The mounting drive 35 is used to drive the rotating rod 31 to move along its axial direction.
[0028] The positioning component 4 includes a positioning bracket 41, a positioning gripper 42, a positioning drive 43, a pressure shaft 44, a pressure cover 45, and an elastic element 46. The positioning bracket 41 is located at the mounting position, the positioning gripper 42 is located on the positioning bracket 41 and is used to clamp the actuator housing, the elastic element 46 is located between the pressure shaft 44 and the pressure cover 45, and the positioning drive 43 is used to drive the pressure shaft 44 to move towards or away from the tray 2.
[0029] It is understood that when the feeding assembly 1 transports the pallet 2 to the installation position, the planetary gear set is placed on the actuator housing by any mechanism, such as a robotic arm. The positioning gripper 42 clamps and fixes the actuator housing, and the positioning drive 43 drives the pressure shaft 44 to press down, so that the pressure cover 45 presses against the upper surface of the planetary gear set, and the elastic element 46 is compressed. Then, the lifting bracket 32 rises under the drive of the lifting drive 33, so that the rotating rod 31 penetrates the actuator housing and presses against the lower surface of the planetary gear set. Finally, the positioning gripper 42 is released from the actuator housing, the installation drive 35 drives the rotating rod 31 to move down, and the rotation drive 34 drives the rotating rod 31 to rotate, which drives the planetary gear set to rotate. At the same time, the pressure cover 45 pushes the planetary gear set down under the elastic force of the elastic element 46. At this time, while the pressure cover 45 presses down on the planetary gear set, the planetary gear set rotates under the drive of the rotating rod 31, realizing the action of pressing down and rotating at the same time, so that the planetary gear set can be smoothly installed into the actuator housing.
[0030] It is understandable that when the rotating rod 31 presses against the lower plane of the planetary gear set, it can be connected to the gears in the planetary gear set, so that the planetary gear set can be driven to rotate together when the rotating rod 31 rotates. Alternatively, it can be not connected to the gears, but can be driven to rotate by friction. There is no limitation here, as long as it can drive the planetary gear set to rotate when the rotating rod 31 rotates.
[0031] It is understandable that both the tray 2 and the actuator housing are provided with through holes, so that the rotating rod 31 can pass through the actuator housing and press against the lower surface of the planetary gear set.
[0032] Furthermore, the feeding assembly 1 includes a conveyor track 11 and a conveyor belt 12, with the conveyor belt 12 disposed on the conveyor track 11 and the pallet 2 placed on the conveyor belt 12.
[0033] It is understood that the conveyor belt 12 can be driven in any way to move on the conveyor track 11 and move the pallet 2.
[0034] Furthermore, the feeding assembly 1 also includes a positioning element 13, which is disposed at the mounting position to prevent the pallet 2 from moving.
[0035] It is understood that when the tray 2 moves to the installation position, the positioning element 13 prevents the tray from moving further. In this embodiment, the positioning element 13 is a blocking cylinder.
[0036] Furthermore, the lifting bracket 32 includes a mounting plate 322 and a lifting plate 323. The mounting plate 322 is fixed to the mounting position and located below the tray 2. The lifting plate 323 is connected to the mounting plate 322 through the lifting drive component 33 and is located between the mounting plate 322 and the tray 2.
[0037] It is understood that when the pallet 2 moves to the mounting position, the pallet 2 is located above the mounting plate 322 and the lifting plate 323. At this time, the lifting drive 33 drives the lifting plate 323 to rise, thereby lifting the pallet 2 off the feeding assembly 1. In this embodiment, the lifting drive 33 is a cylinder.
[0038] Furthermore, a positioning pin 321 is provided on the lifting support plate 323, which is used to position the pallet 2.
[0039] It is understandable that when the lifting plate 323 lifts the pallet 2, the positioning pin 321 positions the pallet 2 and fixes it on the lifting plate 323.
[0040] Furthermore, the mounting drive component 35 includes a servo motor 351, a linear module 352, and a mounting bracket 354. The mounting bracket 354 is connected to the linear module 352. The servo motor 351 is connected to the linear module 352 for driving the movement of the mounting bracket 354 on the linear module 352. The rotation drive component 34 is connected to the mounting bracket 354, and its output end is connected to the rotation rod 31.
[0041] Furthermore, both the mounting plate 322 and the lifting plate 323 are provided with through and concentric through holes. A linear bearing 324 is provided in the through hole of the lifting plate 323. The rotating rod 31 passes through the through hole of the mounting plate 322 and is inserted into the linear bearing 324.
[0042] It is understandable that when installation is required, the servo motor 351 can drive the mounting bracket 354 on the linear module 352 to move downwards. The mounting bracket 354 drives the rotary drive component 34 to move downwards together. The rotating rod 31 moves downwards with the rotary drive component 34. Through the linear bearing 324, the rotating rod 31 moves downwards relative to the lifting plate 323 while also rotating relative to the lifting plate 323.
[0043] Furthermore, the positioning component 4 also includes a gripper cylinder 47, which is used to drive the positioning gripper 42 to grip or release the actuator housing.
[0044] Furthermore, the pressure cap 45 is slidably connected to the pressure shaft 44, and the elastic element 46 is sleeved on the pressure shaft 44 and located between the pressure cap 45 and the pressure shaft 44.
[0045] Furthermore, the positioning drive component 43 is a pneumatic slide.
[0046] Furthermore, the positioning component 4 also includes a positioning sensor and a pressure sensor. The positioning sensor is used to detect whether the planetary gear set is placed on the actuator housing when the positioning gripper 42 clamps the actuator housing; the pressure sensor is used to detect whether the pressure cover 45 presses down on the planetary gear set and whether the elastic element is compressed.
[0047] The working principle of this utility model is as follows: In the initial state, the actuator housing and planetary gear assembly to be assembled are placed on the tray 2. When assembly is required, the feeding component 1 transports the tray 2 to the installation position, and the lifting drive component 33 drives the lifting bracket 32 to move upward to lift and fix the tray 2. At this time, the planetary gear assembly on the tray 2 is placed at the entrance of the actuator housing through an external mechanism, ready for assembly. When assembly begins, the positioning gripper 42 clamps and fixes the actuator housing on the tray 2, and the positioning drive component 43 drives the pressure shaft 44 to move towards the actuator housing until the pressure cover 45 abuts against the upper surface of the planetary gear set and the elastic element is compressed. The installation drive component 35 drives the rotating rod 31 to move upward and pass through the lifting bracket 32 and the lower surface of the actuator housing, abutting against the lower surface of the planetary gear set. Finally, the positioning gripper 42 releases the actuator housing, and the installation drive 35 drives the rotating rod 31 to move downward. At the same time, the rotation drive 34 drives the rotating rod 31 to rotate. At this time, the pressure cover 45 presses down the planetary gear set under the elastic force of the elastic member 46. The rotating rod 31 drives the planetary gear set to rotate at the same time, forming the action of pressing down and rotating the planetary gear set at the same time, so as to smoothly install the planetary gear set into the actuator housing and complete the assembly.
[0048] As can be seen from the above, this utility model uses the elastic force of the elastic element to drive the pressure cover to press down on the planetary gear set, while using the rotating rod to drive the planetary gear set to rotate. The rotating rod moves down synchronously under the drive of the installation drive component, so that the planetary gear set forms a pressing and rotating action, thus achieving the effect of smoothly installing the planetary gear set into the actuator housing.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
