[0042] like Figure 1 As shown, an embodiment of this application provides a transfer device 100, mainly used in robots. The transfer device 100 includes a support 110, a linear drive 120, a rotary drive 130, and a vacuum suction device 140.
[0043] See also Figure 2The fixed end of the linear drive 120 is connected to the support 110, the fixed end of the rotary drive 130 is connected to the output end of the linear drive 120, the vacuum adsorption component 140 is connected to the output end of the rotary drive 130, and the vacuum adsorption component 140 is used to adsorb the workpiece 200.
[0044] The transfer device 100 provided in the embodiments of this application connects the fixed end of the linear drive member 120 to the support 110 and connects the fixed end of the rotary drive member 130 to the output end of the linear drive member 120, so that the rotary drive member 130 can directly follow the output end of the linear drive member 120 to reciprocate linearly.
[0045] Meanwhile, by connecting the vacuum adsorption component 140 used to adsorb the workpiece 200 to the output end of the rotary drive component 130, the vacuum adsorption component 140 can directly follow the output ends of the rotary drive component 130 and the linear drive component 120 to move back and forth linearly in sync, and the vacuum adsorption component 140 can directly follow the output end of the rotary drive component 130 to rotate relative to the fixed end of the rotary drive component 130.
[0046] In this way, by using direct drive, the size of the transfer device 100 is effectively reduced, the structure of the transfer device 100 is simplified, and the transmission error and wear caused by intermediate transmission are reduced, thereby effectively improving the motion accuracy of the transfer device 100.
[0047] For example, the linear drive 120 can be a linear drive motor, the rotary drive 130 can be a direct drive motor, and the vacuum suction component 140 can be a vacuum suction cup.
[0048] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the transfer device 100 further includes a connector 150, which is connected to the output end of the linear drive 120 and the fixed end of the rotary drive 130, respectively.
[0049] In this embodiment, by providing a connector 150 that is connected to the output end of the linear drive 120 and the fixed end of the rotary drive 130 respectively, the fixed end of the rotary drive 130 is fixedly connected to the output end of the linear drive 120 through the connector 150, thereby enabling the fixed end of the rotary drive 130 to reciprocate linearly and stably in sync with the output end of the linear drive 120 through the connector 150.
[0050] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the support 110 is provided with a guide rail 111, and the connector 150 is slidably connected to the guide rail 111.
[0051] In this embodiment, by setting a guide rail 111 on the support 110 and slidingly connecting the connector 150 to the guide rail 111, the output end of the linear drive 120 and the fixed end of the rotary drive 130 are slidably connected to the guide rail 111 on the support 110 through the connector 150, so as to play a guiding role, thereby helping to further improve the reciprocating linear motion accuracy of the transfer device 100.
[0052] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the support 110 is provided with a limiting groove 112, the limiting groove 112 extends along the movement direction of the linear drive member 120, and the connector 150 is provided with a limiting protrusion 151 that is adapted to the limiting groove 112.
[0053] In this embodiment, a limiting groove 112 is provided on the support 110 along the movement direction of the linear drive member 120, and a limiting protrusion 151 adapted to the limiting groove 112 is provided on the connector 150. Under the limiting action of the limiting groove 112 on the limiting protrusion 151, the stroke limitation function of the reciprocating linear motion of the connector 150 is realized, thereby realizing the overall stroke limitation function of the output end of the linear drive member 120 and the fixed end of the rotary drive member 130.
[0054] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the transfer device 100 further includes a guide 160 and an elastic member 170. One end of the guide 160 is fixedly connected to the fixed end of the rotary drive 130, and the other end is movably connected to the connector 150. The elastic member 170 is sleeved on the guide 160 and abuts against the fixed end of the rotary drive 130 and the connector 150, respectively.
[0055] In this embodiment, one end of the guide member 160 is fixedly connected to the fixed end of the rotary drive member 130, and the other end of the guide member 160 is movably connected to the connector 150, so that the fixed end of the rotary drive member 130 and the connector 150 are integrated, and the fixed end of the rotary drive member 130 can move relative to the connector 150. Simultaneously, by sleeved on the guide member 160 and abutting against both the fixed end of the rotary drive member 130 and the connector 150, the elastic force of the elastic member 170 provides a buffering and vibration-damping effect on the connection between the fixed end of the rotary drive member 130 and the connector 150, thereby improving the stability and lifespan of the rotary drive member 130.
[0056] For example, guide 160 can be a guide pin and elastic element 170 can be a cylindrical spring.
[0057] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the transfer device 100 further includes a mounting member 181 and a balancing support member 182. The mounting member 181 is connected to the output end of the rotary drive member 130, and the balancing support member 182 is movably mounted on the mounting member 181 for balancing and supporting the workpiece 200.
[0058] In this embodiment, by connecting the mounting member 181 to the output end of the rotary drive member 130 and movably mounting the balance support member 182 on the mounting member 181, the workpiece 200 is supported and balanced, thereby improving the adsorption effect of the vacuum adsorption member 140 on the workpiece 200.
[0059] For example, the balance support 182 is slidably mounted on the mounting member 181.
[0060] like Figure 1 and Figure 2 As shown, in the above embodiments of this application, two balance supports 182 are provided, and the two balance supports 182 are respectively located on two opposite sides of the vacuum adsorption member 140.
[0061] In this embodiment, by setting the number of balancing support members 182 to two and placing the two balancing support members 182 on opposite sides of the vacuum adsorption member 140, the support and balancing effect on the workpiece 200 is further improved, thereby further improving the adsorption effect of the vacuum adsorption member 140 on the workpiece 200.
[0062] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the transfer device 100 further includes a connecting pipe 190, one end of which is connected to the vacuum adsorption member 140, and the other end passes through the rotary drive member 130 and the linear drive member 120 in sequence, for connection to an external negative pressure device.
[0063] In this embodiment, one end of the connecting tube 190 is connected to the vacuum adsorption component 140, and the other end of the connecting tube 190 passes sequentially through the rotary drive component 130 and the linear drive component 120 and is connected to an external negative pressure device. This allows the vacuum adsorption component 140 to connect to the external negative pressure device via the connecting tube 190, thereby enabling the vacuum adsorption component 140 to adsorb the workpiece 200. Furthermore, the structure of the connecting tube 190 passing sequentially through the rotary drive component 130 and the linear drive component 120 prevents the connecting tube 190 from rotating with the output end of the rotary drive component 130, thus avoiding the problem of the connecting tube 190 becoming tangled and knotted, which would affect vacuum adsorption.
[0064] In one embodiment of this application, the transfer device 100 further includes a controller, which is electrically connected to the rotary drive 130 and the linear drive 120, respectively.
[0065] In this embodiment, by electrically connecting the controller to the rotary drive 130 and the linear drive 120 respectively, precise control of the rotary drive 130 and the linear drive 120 is achieved, thereby ensuring the motion accuracy of the transfer device 100. For example, the controller can be a programmable logic controller.
[0066] This application also provides a robot, including a robotic arm and the transfer device 100 described in the above embodiments, wherein the support 110 is connected to the robotic arm.
[0067] The robot has the transfer device 100 in any of the above embodiments, and therefore has all the beneficial effects of the transfer device 100, which will not be described in detail here.
