[0042] Example 1:

[0043] This embodiment relates to a motion carrier for a linear motor, installed within the motor housing 1, for integrating linear and rotary motion functions. It is particularly suitable for industrial applications requiring high precision and repeatability, such as 3C manufacturing, semiconductor processing, and precision assembly. This embodiment aims to address the problems of structural complexity and reduced detection accuracy of the pressure sensor 401 when simultaneously mounting a pressure sensor 401 and a gas pipeline on the motion carrier within a ZR robot in existing technologies.

[0044] Figure 1 This is a schematic diagram of the overall assembly structure of this utility model. Figure 2 This is a cross-sectional view of the moving carrier in this utility model. Figure 3 This is a three-dimensional structural diagram of the moving carrier in this utility model. Figure 4 This is an enlarged view of the connection structure between the carrier body 2 and the pressure sensor assembly 4. Figure 5 for Figure 4 A schematic diagram of the bottom structure. Figure 6 This is an enlarged structural schematic diagram of the pressure sensor assembly 4 in this utility model;

[0045] like Figures 1 to 6The illustrated motion carrier for a linear motor is installed within a motor housing 1 and includes a carrier body 2. The carrier body 2 serves as a basic support structure, with a first mounting portion 204 integrally or detachably connected to its top for mounting a rotary motor. A second mounting portion 207 is located at the bottom of the carrier body 2. This second mounting portion 207 is a bushing mounting end for connecting a support bushing 7 to a motor output shaft 301. The motor output shaft 301 is used to connect to an external gripping component, and the support bushing 7 provides support and protection for the motor output shaft 301. The present invention also includes a cavity 202 inside the carrier body 2 to provide necessary rotation space for the space-constrained motor output shaft 301, ensuring that the motor output shaft 301 can rotate freely without obstruction. Specifically, as shown... Figure 2 As shown, a first sealing element 8 and a second sealing element 9 are installed in the cavity 202. The first sealing element 8 and the second sealing element 9 adopt annular sealing rings, which can prevent external dust and impurities from entering the cavity 202 and also prevent lubricant from leaking out. Through the joint action of the first sealing element 8 and the second sealing element 9, a double sealing structure is formed, which enhances the sealing effect.

[0046] This invention provides a sensor limiting component 205 on the carrier body 2 to limit the pressure sensor assembly 4. Specifically, a protrusion 2071 is integrally connected to the bushing mounting end 207 of the carrier body 2. A positioning groove 203 is formed between the protrusion 2071 and the pressure sensor assembly 4. The positioning groove 203 is used to limit the pressure sensor assembly 4. At the same time, this invention leaves gaps between the pressure sensor assembly 4 and the protrusion 2071 and the sensor limiting component 205 to allow the pressure sensor 401 to deform. This allows the pressure sensor 401 to have a certain deformation margin, which facilitates the pressure sensor 401 to respond to pressure changes and perform measurements. In this invention, an air passage is provided in the protrusion 2071, which is connected to the internal cavity of the carrier body 2. An air pipe connector 2072 is installed on the protrusion 2071 for connecting to the air pipeline. The air pipeline can be a flexible hose or a rigid pipe. Furthermore, the flexible hose can be a rubber hose or a silicone hose, and the rigid pipe can be a polyvinyl chloride pipe, a polycarbonate pipe, or a polypropylene pipe.

[0047] The sensor limiting component 205 in this invention can also fix the pressure sensor assembly 4. Specifically, the sensor limiting component 205 and the pressure sensor 401 can be fixed by adhesive bonding. Appropriate glue or adhesive can be used to bond the pressure sensor assembly 4 to the sensor limiting component 205. This fixing method is suitable for applications where frequent sensor disassembly is not required, ensuring that the pressure sensor assembly 4 will not shift during use. The sensor limiting component 205 and the pressure sensor 401 can also be fixed by screws. A threaded hole is provided at the bottom of the sensor limiting component 205, allowing the pressure sensor assembly 4 to be fastened to the limiting component using screws. This fixing method provides a stable connection and is suitable for applications where the pressure sensor 401 needs to remain in the same position for extended periods.

[0048] This invention features a guide channel 206 formed between the sensor limiting member 205 and the first mounting part 204. The guide channel 206 guides the air passage. An inclined surface 2051 is provided on the sensor limiting member 205 to guide the air passage into the guide channel 206, helping it to smoothly enter and preventing damage from excessive bending. A clearance groove 2042 is provided on the first mounting part 204, and a coupling assembly groove 201 is provided within the carrier body 2. The coupling assembly groove 201 provides space for the coupling 5, facilitating the connection of the motor output shaft 301 of the rotary motor 3 to the load end. A clearance groove 2042 is also provided on the first mounting part 204. The clearance groove 2042 is located on the front end side of the first mounting part 204. The clearance groove 2042 can make the installation of the coupling 5 more convenient and reduce obstacles in the installation process. A through hole 2041 is provided on the coupling assembly groove 201. The through hole 2041 is used to guide the motor output shaft 301 of the rotary motor 3. The present invention provides a weight reduction groove 208 on the contact surface between the carrier body 2 and the motor housing 1, which can effectively reduce the overall weight of the structure.

[0049] The pressure sensor assembly 4 of this invention includes a pressure sensor 401, a first fixing member 402, and a second fixing member 403. The pressure sensor 401 is installed between the first fixing member 402 and the second fixing member 403. The pressure sensor 401 is a key component for detecting pressure changes. It converts pressure signals into electrical signals so that the control system can read these signals and make corresponding adjustments or responses. Specifically, the pressure sensor 401 includes a sensitive element and a signal conversion circuit. The sensitive element (such as a diaphragm, Bourdon tube, etc.) deforms according to changes in pressure. This deformation is converted into a measurable electrical signal by the signal conversion circuit. This invention connects an output line 4011 to the pressure sensor 401. The output line 4011 can be one or more wires. The pressure sensor 401 is connected to the control system through the output line 4011 to transmit the electrical signals generated by the pressure sensor 401 so that the control system can perform corresponding processing and control based on these signals. In practical applications, the control system controls the start, stop, and speed adjustment of the rotary motor 3 based on the data provided by the pressure sensor 401. For example, when grasping an object, the control system can determine whether the object has been successfully grasped by monitoring the data from the pressure sensor 401, and adjust the robotic arm's force according to the object's weight and size to avoid damaging the object or failing to grasp it. The first fixing member 402 is fixedly connected inside the motor housing 1 (the first fixing member 402 is a metal or plastic mounting base, fixedly connected to the motor housing 1 by screws, clips, or other fixing methods), ensuring the stability of the pressure sensor assembly 4. The second fixing member 403, together with the first fixing member 402, fixes the pressure sensor 401, ensuring that the pressure sensor assembly 4 can be stably installed in the designated position.

[0050] This utility model provides a detachable hose guide structure on the carrier body 2. Specifically, the hose guide structure is an air passage guide 6. A guide groove 601 is provided in the air passage guide 6 to guide the direction of the air passage in the vertical direction, so as to ensure that the air passage can be correctly arranged and guided in the complex structure inside the motor housing 1.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
