Description

Technical Field

[0001] This utility model relates to the field of gasket installation technology, specifically a gasket assembly robot. Background Technology

[0002] Washers are sometimes installed on shafts or inside holes of automotive parts. To achieve sealing and lubrication, a layer of oil is applied to the surface of the washer. Traditionally, washers are installed manually. However, when manually assembling washers, the amount of lubricant applied is uncontrollable, leading to uneven application and quality issues. Furthermore, manual operation increases the operator's time, which is not conducive to the demands of rapid mass production. Therefore, we propose a washer assembly robot. Utility Model Content

[0003] This utility model provides a washer assembly robot, which has the functions of automatically picking up and installing washers, and can also apply oil to the washers after they are installed, thus solving the problems mentioned in the background art.

[0004] The technical solution of this utility model is implemented as follows: A washer assembly robot is designed, including a multi-axis robotic arm. A mounting frame is provided on the free end of the multi-axis robotic arm. A support tube is also included. An annular seat is coaxially provided at the bottom of the support tube. At least two air pipes and at least one oil pipe are symmetrically provided on the side of the support tube. Multiple channels are provided in the annular seat, which correspond to the positions of the air pipes and oil pipes respectively. The upper and lower ends of the channels are connected to the outside. The top of the channels is sealed to the ends of the air pipes and oil pipes respectively. The top of the air pipes is connected to a negative pressure device. The top of the oil pipes is connected to an oil supply device. The top of the support tube is connected to a drive device. The drive device drives the support tube to rotate. The drive device is mounted on the mounting frame.

[0005] Preferably, the multi-axis robotic arm is a six-axis robotic arm or a multi-axis gantry robotic arm.

[0006] Preferably, the top of the mounting bracket is provided with a connecting flange, which is detachably connected to the free end of the multi-axis robotic arm.

[0007] Preferably, the driving device includes a drive motor, which is mounted on a mounting base, and one end of the mounting base is connected to the mounting frame.

[0008] Preferably, mounting flanges are provided on the shaft of the drive motor and the top of the support tube, and the upper and lower mounting flanges are detachably connected.

[0009] Preferably, the top of the support tube is coaxially provided with an air slip ring and an oil slip ring. The stators of both the air slip ring and the oil slip ring can be detachably mounted on the mounting bracket, while the rotors of both the air slip ring and the oil slip ring can be detachably mounted on the support tube.

[0010] Preferably, openings are provided on the support pipe between the air slip ring and the oil slip ring, as well as on the support pipe above the vent pipe and the oil pipe.

[0011] Compared with the prior art, in use, the multi-axis robotic arm drives the support tube to adsorb the gasket. Then, the multi-axis robotic arm first moves the support tube to the port of the gasket installation location, allowing the support tube to extend into the installation location, thus placing the gasket at the installation location. Moreover, the support tube rotates under the drive of the drive motor, allowing the oil that does not flow out of the oil pipe to be applied to the gasket, thus realizing the function of grasping the gasket and then applying oil to the gasket.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 6 This utility model provides a technical solution: a washer assembly robot, including a multi-axis robotic arm 1, which is a six-axis robotic arm or a multi-axis truss robotic arm. The multi-axis truss robotic arm can be a three-axis, four-axis, five-axis, or six-axis truss robotic arm. A mounting bracket 4 is provided on the free end of the multi-axis robotic arm 1. Figure 2 As shown, specifically, a connecting flange 2 is provided on the top of the mounting frame 4. The connecting flange 2 is detachably connected to the free end of the multi-axis robotic arm 1, and the connecting flange 2 is fastened to the multi-axis robotic arm 1 by bolts.

[0022] This application also includes a support tube 7, such as Figure 4 and Figure 5 As shown, the top of the support tube 7 is connected to the drive device, which drives the support tube 7 to rotate. The drive device is mounted on the mounting bracket 4. The drive device includes a drive motor 3, which is mounted on a mounting base 8. One end of the mounting base 8 is connected to the mounting bracket 4. Specifically, mounting flanges 14 are provided on both the shaft of the drive motor 3 and the top of the support tube 7. The two mounting flanges 14 are detachably connected, meaning that the edges of the two mounting flanges 14 are fastened with bolts. The drive motor 3 can drive the support tube 7 to rotate.

[0023] The bottom of the support tube 7 is coaxially provided with an annular seat 10, such as... Figure 1 and Figure 2 As shown, the diameter of the annular seat 10 is larger than the diameter of the support tube 7, so that the annular seat 10 and the bottom of the support tube 7 are set in a stepped manner. It should be noted that the size of the annular seat 10 matches the diameter of the picked-up washer.

[0024] At least two vent pipes 9 and at least one oil pipe 11 are symmetrically arranged on the side of the support pipe body 7. In practice, there are two vent pipes 9 and one oil pipe 11. Figure 6As shown, the annular seat 10 has multiple channels 13 corresponding to the positions of the vent pipe 9 and the oil pipe 11. Importantly, the upper and lower ends of the channels 13 are connected to the outside, and the tops of the channels 13 are sealed to the ends of the vent pipe 9 and the oil pipe 11, respectively. It should be noted that the vent pipe 9 is used to exhaust air, while the oil pipe 11 supplies oil downwards to the annular seat 10. When the vent pipe 9 exhausts air, the annular seat 10 forms an annular suction cup, as... Figure 4 and Figure 5 As shown, the ring seat 10 can adsorb the washer located at its bottom, and the washer can then operate according to the set route under the drive of the multi-axis robotic arm 1.

[0025] Specifically, the top of the vent pipe 9 is connected to the negative pressure device, which is a high-pressure air pump, and the top of the oil pipe 11 is connected to the oil supply device, which is an oil supply pump.

[0026] The specific situation is as follows, such as Figure 1 and Figure 2 As shown, an air slip ring 5 and an oil slip ring 6 are coaxially arranged on the top of the support tube 7. During installation, the stator of the air slip ring 5 and the stator of the oil slip ring 6 can be detachably installed on the mounting bracket 4, that is, fastened to the mounting bracket 4 by bolts. The rotor of the air slip ring 5 and the rotor of the oil slip ring 6 can be detachably installed on the support tube 7, and the rotor is fastened to the support tube 7 by bolts.

[0027] During installation, the stator of the air slip ring 5 is connected to the reversing solenoid valve through a pipe, the reversing solenoid valve is connected to the high-pressure air pump through a pipe, the stator of the oil slip ring 6 is connected to the solenoid valve through a pipe, and the solenoid valve is connected to the oil supply pump through a pipe.

[0028] like Figure 4 and Figure 5 As shown, openings 12 are provided on the support pipe 7 between the air slip ring 5 and the oil slip ring 6, as well as on the support pipe 7 above the vent pipe 9 and the oil pipe 11. The openings 12 are used for pipe insertion, that is, the pipe connecting the rotors of the air slip ring 5 and the oil slip ring 6 is inserted into the support pipe 7 through the upper opening 12, and then exits from the lower opening 12 to connect with the top of the vent pipe 9 and the oil pipe 11, thereby realizing the passage of oil and air.

[0029] Based on the above embodiments, the specific operation process is as follows: the multi-axis robotic arm 1 drives the support tube 7 to adsorb the gasket, and then the support tube 7 can move towards the gasket installation location under the drive of the multi-axis robotic arm 1, such as... Figure 4 As shown, the multi-axis robotic arm 1 first moves the support tube 7 to the port where the washer is installed, as... Figure 5 As shown, the support tube 7 then extends into the mounting location. Once the washer is placed in the mounting groove, the extension process of the support tube 7 stops.

[0030] Then the suction force of the vent pipe 9 stops, at which point the gasket is placed in the groove. The support pipe 7 then rotates under the drive of the motor 3, and simultaneously, the oil pipe 11 begins supplying oil. The oil supply flow is slow to avoid oil spraying out; precise control of the oil reservoir is required. As the support pipe 7 rotates, the oil flowing from the bottom of the annular seat 10 can be applied to the gasket. Then, the support pipe 7 is pulled out from the gasket mounting location to allow for the next gasket installation.

[0031] Based on the above embodiments, it should be further explained that the support tube 7 can not only install washers inside the holes, but also install washers on the shaft. For example... Figure 4 and Figure 5 As shown, when installing the washer inside the hole, the support tube 7 extends into the hole. However, when installing the washer on the shaft, it is only necessary to place the shaft inside the support tube 7 and let the washer fit on the shaft. The operation process is the same as that for installation inside the hole.

[0032] Furthermore, the ring seat 10 can also install washers on a flat surface; it only requires picking up the washer and placing it in the washer installation position.

[0033] Based on the above embodiments, it should be further explained that the bottom of the annular seat has an oleophobic layer, and the surfaces of the annular seat and the support tube are also provided with an oleophobic layer. This can prevent oil from remaining at the bottom of the annular seat, and the oil storage volume of the oil pipe is precisely controlled, so there will be no oil at the bottom of the annular seat.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
