Abstract
Description
Technical Field
[0001] This application relates to the field of automatic assembly technology, specifically to a rotating mechanism and a pressing device. Background Technology
[0002] With the development of new energy vehicles, the requirements for automation in production are becoming increasingly stringent. New energy vehicles often have water pipes, at both ends of which connectors are needed. To ensure a tight seal between the water pipe and the connector, an interference fit is typically used. While this method guarantees a tight seal, during the automated connection process, the water pipe is prone to yielding and deformation, affecting the efficiency of automated assembly.
[0003] In existing technology, an expander is used to first enlarge the water pipe opening, increasing its diameter. The diameter of the connector is smaller than or equal to the expanded water pipe opening diameter, making it easier to insert the connector into the water pipe opening. Guided by the water pipe opening, the connector is then gradually inserted into the gradually decreasing diameter water pipe, thus improving the assembly success rate. Existing connector assembly procedures include at least three steps: material loading, hole enlargement, and assembly. The next cycle begins only after these steps are completed. However, during this cycle, because assembly requires continuously inserting the connector into the water pipe opening, this step takes a long time, and the overall cycle time for completing the three steps is correspondingly increased, resulting in low water pipe assembly efficiency.

[0006] The turntable and motor are connected by a drive to the turntable. At least two material-carrying modules and expansion modules are installed on the turntable, and the material-carrying modules and expansion modules are located on the same rotation circumference on the turntable.
[0007] In one embodiment, the expansion module includes a cone with its tip located on the circumference of rotation.
[0008] In one embodiment, the loading module has a second receiving groove, the center of which is located on the circumference of rotation.

[0018] In one embodiment, the base and the bottom plate are slidably connected by a slider and a slide rail.
[0019] This application has at least the following beneficial effects:
[0020] The rotating mechanism in this application has two loading modules. While one loading module is assembling the connector and the water pipe, the other loading module is loading the connector. Although the connector assembly step still includes three steps: loading, hole enlargement, and assembly, the loading time of the connector and the assembly time of the connector and the water pipe overlap in the two cycles. In fact, the assembly time is reduced by the loading time, which shortens the assembly cycle time and improves the assembly efficiency. Attached Figure Description

[0045] The embodiments of this application are described in detail below with reference to the accompanying drawings.
[0046] Reference Figure 1 , 3As shown, in some embodiments of this application, a pressing device is provided, including: a rotating assembly 100, a base 200, and a clamping assembly 300. The clamping assembly 300 is used to load a water pipe 41 and is mounted on the base 200. Specifically, the base 200 includes a housing, the clamping assembly 300 is fixedly connected to the housing, and the base 200 has a built-in linear drive module 21. The rotating assembly 100 is connected to the linear drive module 21. The linear drive module 21 can drive the rotating assembly 100 to move relative to the base 200, thereby enabling the rotating assembly 100 to move relative to the clamping assembly 300.
[0047] In this scheme, the rotating component 100 is equipped with a connector 42. Under the drive of the linear drive module 21, the rotating component 100 brings the connector 42 close to the water pipe 41 on the clamping component 300 and finally connects the connector 42 to the water pipe 41.
[0048] In some embodiments of this application, the rotating assembly 100 includes a base plate 11, a turntable 12, a bracket 13, and a motor 14. The bracket 13 is mounted on the base plate 11, and in this embodiment, the bracket 13 stands upright on the base plate 11. The motor 14 is fixedly connected to the bracket 13, and the turntable 12 is connected to the power output end of the motor 14. The bracket 13 supports the turntable 12 at a fixed height. It is understood that the fixed height is adapted to the height of the water pipe 41 loaded on the clamping assembly 300.
[0049] A transmission structure is also provided between the turntable 12 and the motor 14. For example, the transmission structure is a planetary gear transmission structure. In this solution, at least two material-carrying modules 16 and expansion modules 15 are installed on the turntable 12. Preferably, there are two material-carrying modules 16, each including a first carrier 1601 and a second carrier 1602. At any given time, at least one of the first carrier 1601 and the second carrier 1602 contains a connector 42. The first carrier 1601, the second carrier 1602, and the expansion module 15 are located on the same rotation circumference C on the turntable 12.
[0050] It is understandable that the number of material-carrying modules 16 can also be three, four, or even more. Meanwhile, the number of expansion modules 15 can also increase proportionally with the increase in the number of material-carrying modules 16. In another specific embodiment, based on the scheme that the number of expansion modules 15 increases proportionally with the number of material-carrying modules 16 (specifically, the ratio of the number of material-carrying modules 16 to the number of expansion modules 15 is 2:1), multiple water pipes 41 can be assembled simultaneously.
[0051] The expansion module 15 can enlarge the opening diameter of the water pipe 41. The pressing device uses the expansion module 15 to enlarge the opening of the water pipe 41 loaded on the clamping assembly 300. Specifically, the rotation circumference C is a circle with the rotation axis of the turntable 12 as the center and the distance from the loading module 16 and the expansion module 15 to the center as the radius.
[0052] The rotating assembly 100 has an assembly station and a loading station. The turntable 12 rotates to align the two loading modules 16 with the assembly station and the loading station, respectively. Simultaneously, the expansion module 15 can rotate to the assembly station. The loading module 16 at the assembly station cooperates with the clamping assembly 300, allowing the connector 42 of the loading module 16 at the assembly station to be inserted into the water pipe 41. An external loading device is positioned corresponding to the loading station, loading the connector 42 onto the loading module 16 at the loading station. For example, the assembly station is located at the lowest point in the vertical direction of the rotation circumference C, while the loading station is located at the highest point in the vertical direction of the rotation circumference C.
[0053] The clamping assembly 300 has a clamping space in which the water pipe 41 is placed and clamped to restrict its displacement. In this design, the central axis of the clamping space is projected onto the circumference of rotation, ensuring that after the rotating assembly 100 moves toward the clamping assembly 300, either the expansion module 15 or the connector 42 can accurately contact the water pipe 41 on the clamping assembly 300. More specifically, the central axis of the clamping space corresponds to the assembly station setting.
[0054] Furthermore, combined Figure 2 As shown, the expansion module 15 includes a cone 151, the tip of which is located on the aforementioned circumference of rotation, meaning the center point of the cone 151 is located on the baseline of the aforementioned circumference of rotation. The cone 151 is conical in shape. Because the center point of the cone 151 is located on the aforementioned circumference of rotation, the central axis of the cone 151 is collinear with the axis of the water pipe 41, allowing the cone 151 to smoothly extend into the water pipe 41 and enlarge the water pipe opening. After the cone 151 is inserted into the water pipe 41, it forces the opening of the water pipe 41 to deform, increasing the opening area near the end face of the water pipe 41, thus facilitating the insertion of the connector 42 into the water pipe 41.
[0055] The connector 42 includes an integral adapter 421 and a plug-in portion 422, wherein the plug-in portion 422 is inserted into the water pipe 41. The loading module 16 has a first receiving groove 161 and a second receiving groove 162 that are connected. The adapter 421 is housed in the first receiving groove 161, and the plug-in portion 422 is inserted into the second receiving groove 162, with the portion of the plug-in portion 42 inserted into the water pipe 41 extending out of the second receiving groove 162. The center of the second receiving groove 162 is located on the reference line of the rotation circumference C. Specifically, the center of the second receiving groove 162 is the point located on the axis of the plug-in portion 42 when it is housed in the second receiving groove 162.
[0056] Furthermore, the loading modules 16 are evenly distributed on the rotating circumference. Specifically, the angle formed by the center of the second receiving groove 162 in the two loading modules 16 to the rotation axis of the turntable 12 is 180°. In this scheme, since the assembly station and the loading station are respectively located at the lowest and highest positions in the vertical direction of the rotating circumference C, and since the angle formed by the center of the two second receiving grooves 162 to the rotation axis of the turntable 12 is 180°, it is ensured that when one loading module 16 is located at the assembly station, the other loading module 16 is located at the loading station. When the connector 42 on one loading module 16 is assembled to the water pipe 41, the other loading module 16 can be loaded with a new connector 42 to perform the next assembly operation.
[0057] Meanwhile, on the rotating circumference C, the distances from the expansion module 15 to the two material-carrying modules 16 are consistent. That is, the angle formed by the center point of the cone 151 and the center of any second receiving slot 162 to the rotation axis of the turntable 12 is 90°. Based on the above layout design of the expansion module 15 and the material-carrying module 16 on the turntable 12, the motor 14 drives the turntable 12 to rotate clockwise and counterclockwise reciprocally, with a rotation angle of 180°, and pauses when it has rotated 90° clockwise or counterclockwise, thus simplifying the control logic of the motor 14.
[0058] In some embodiments of this application, reference is made to Figure 4-6As shown, a pressure sensing module 18 is provided between the base plate 11 and the linear drive module 21. The pressure sensing module 18 is used to detect the pressure generated by the rotating component 100 pressing against the clamping component 300. The pressure sensing module 18 includes a pressure sensor 185. A fixed seat 183 and a connecting seat 184 are spaced apart on the base plate 11. The pressure sensor 185 is connected between the fixed seat 183 and the connecting seat 184. The connecting seat 184 is installed at the power output end 211 of the linear drive module 21. More specifically, a guide rail 181 is installed on the base plate 11, and a guide block 182 is slidably connected to the guide rail 181. The connecting seat 184 is installed on the guide block 182. The sliding direction of the guide block 182 is consistent with the driving direction of the linear drive module 21. The fixed seat 183 is fixed to the base plate 11, and the guide block 182 and the connecting seat 184 can move relative to the fixed seat 183. The two ends of the pressure sensor 185 are connected to the fixing base 183 and the connecting base 184 by screws. When the rotating assembly 100 presses against the clamping assembly 300, the pressure sensor 185 is squeezed between the guide block 182 and the connecting base 184. The pressure sensor 185 detects the squeezing force, which is equivalent to the pressure between the connector 42 and the water pipe 41. After the connector 42 and the water pipe 41 are assembled, the connecting base 184 drives the fixing base 183 and the base plate 11 to move through the pressure sensor 185, so that the rotating assembly 100 moves away from the clamping assembly 300.
[0059] Furthermore, the base 200 and the base plate 11 are slidably connected via a slider 17 and a slide rail 22. The slide rail 22 is mounted on the outer casing, and the slider 17 is mounted on the base plate 11. The slider 17 and the slide rail 22 are slidably connected to guide the rotating component 100 to move relative to the base 200 in a straight line. The extension direction of the slide rail 22 is consistent with the extension direction of the guide rail 181. Specifically, there are two slide rails 22, and multiple sliders 17 are mounted on the base 200. Each slider 17 corresponds to any one of the slide rails 22 to improve the stability of the rotating component 100's movement.
[0060] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
