[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a variable-pitch loading and transfer device includes: an X-axis frame 1, a Y-axis frame 11 mounted at the bottom of the X-axis frame 1, and a Z-axis frame 12 mounted on one side of the X-axis frame 1; a mounting box 2 is provided on one side of the Z-axis frame 12, and a transfer pitch-changing mechanism is provided at the bottom of the mounting box 2; translation components for providing translational forces in the X, Y, and Z axis directions are provided on one side of the X-axis frame 1, the top of the Y-axis frame 11, and one side of the Z-axis frame 12, and limiting components for providing stable translation during translation are also provided; the transfer pitch-changing mechanism includes: fixed to the mounting box 2. A fixed block 3 at the bottom, several transfer plates 31 set at the bottom of the fixed block 3, and several negative pressure suction cups 32 installed at the bottom of the transfer plates 31; several linear guide rails 33 are fixed at the bottom of the fixed block 3, and several sliders 34 are fixed at the top of the transfer plates 31, with the tops of the sliders 34 slidably connected to the bottoms of the linear guide rails 33; a power mechanism for driving the transfer plates 31 on both sides to move closer synchronously is installed inside the fixed block 3, and a spacing maintaining component for maintaining the distance between adjacent transfer plates 31 is installed between the transfer plates 31.
[0029] It should be noted that the negative pressure suction cups 32 and the transfer plates 31 are evenly distributed in a linear array, and the sliders 34 on the transfer plates 31 are staggered with the sliders 34 on adjacent transfer plates 31. During the material loading and transfer operation in the production of buttons, a three-dimensional moving frame is formed by the X-axis frame 1, Y-axis frame 11 and Z-axis frame 12. The mounting box 2 serves as the carrier of the transfer pitch mechanism. With the cooperation of the translation component and the limiting component, it can achieve precise movement in the X, Y and Z directions, ensuring that the negative pressure suction cups 32 at the bottom of the transfer plate 31 can accurately and stably suction the buttons. The buttons located on the worktables at different positions are attached to each other. With the cooperation of the power mechanism, the transfer plates 31 on both sides can be driven to move closer synchronously, so that several sliders 34 can slide stably along several linear guide rails 33. With the cooperation of the spacing maintenance component, the spacing between adjacent transfer plates 31 is maintained, thereby realizing the adjustment and maintenance of the spacing between the transfer plates 31 and the negative pressure suction cup 32. This enables the adaptation to buttons of different sizes, which not only solves the problems of poor size adaptability and low efficiency of small precision parts in the loading and transfer process, but also significantly improves the automation level and flexibility of the production line.
[0030] In some embodiments, a gas flow channel is provided on the inner side of the transfer plate 31, and the inner side of the gas flow channel is connected to the inner side of a plurality of negative pressure suction cups 32. An external negative pressure device is connected to one end of the gas flow channel through a pipeline. When the negative pressure device increases the air pressure, the negative pressure generated can act on the plurality of negative pressure suction cups 32, so that the negative pressure suction cups 32 generate a vacuum adsorption force, which can firmly adsorb the button.
[0031] like Figure 2 and Figure 3 As shown, in some embodiments, the power mechanism includes: a servo motor 4 fixed to one side of the fixed block 3, a lead screw 41 disposed inside the fixed block 3, and a plurality of moving blocks 42 disposed on the side of the lead screw 41; the output end of the servo motor 4 is provided with a transmission component for transmitting rotational motion to the lead screw 41, a limiting groove 43 is opened at the bottom of the fixed block 3, and the bottoms of the plurality of moving blocks 42 penetrate into the inner side of the limiting groove 43 and are respectively fixed to the outermost slider 34.
[0032] It should be noted that the sides of the lead screw 41 near both ends are rotatably connected to the inner side of the fixed block 3 via bearings. The surface of the lead screw 41 is provided with threads in opposite directions. The inner sides of several moving blocks 42 are threadedly connected to the sides of the lead screw 41. When the transfer plates 31 on both sides move closer synchronously, the servo motor 4 drives the lead screw 41 to rotate through the cooperation of the transmission components. Since the surface of the lead screw 41 is provided with threads in opposite directions, when the lead screw 41 rotates, the moving blocks 42 threadedly connected to it will move in opposite directions along the limiting groove 43. This can drive the corresponding outermost slider 34 of the moving block 42 to move synchronously, thereby driving the transfer plate 31 to move closer or further away synchronously, realizing the variable pitch function.
[0033] In some embodiments, the transmission assembly includes: a driving synchronous pulley 5 mounted on the output end of the servo motor 4, a driven synchronous pulley 51 mounted on one end of the lead screw 41, and a toothed belt 52 meshing with the sides of the driving synchronous pulley 5 and the driven synchronous pulley 51.
[0034] It should be noted that when the servo motor 4 is started, it can drive the active synchronous pulley 5 at the output end to rotate. Through the meshing of the toothed belt 52, the driven synchronous pulley 51 at one end of the lead screw 41 can be driven to rotate synchronously by the active synchronous pulley 5, thereby increasing the rotational power of the lead screw 41.
[0035] In some embodiments, the spacing maintaining assembly includes: a plurality of first hinge bars 6 hinged to one side of the external transfer plate 31, and a plurality of second hinge bars 61 hinged to one side of the central transfer plate 31; one end of the plurality of first hinge bars 6 is hinged to one end of the plurality of second hinge bars 61.
[0036] It should be noted that the hinge point between the first hinge strip 6 and the transfer plate 31 is located at one end of the first hinge strip 6, and several first hinge strips 6 are stacked on top of each other in a V-shape; the hinge point between the second hinge strip 61 and the transfer plate 31 is located in the middle of the second hinge strip 61, and several second hinge strips 61 are stacked on top of each other in a cross shape; when the transfer plate 31 moves, through the hinged connection between the first hinge strip 6 and the second hinge strip 61, the hinged and stacked method of the first hinge strip 6 and the second hinge strip 61 allows it to adaptively adjust its shape as several transfer plates 31 move, avoiding deformation or misalignment, thereby ensuring the stability of the transfer plate 31 during movement and the consistency of the spacing between adjacent transfer plates 31.
[0037] In some embodiments, in the planar direction, the translation component on one side of the X-axis frame 1 is perpendicular to the translation component on the top of the Y-axis frame 11; in the vertical direction, the translation component on one side of the X-axis frame 1 is perpendicular to the translation component on one side of the Z-axis frame 12.
[0038] It should be noted that the translation component includes at least: a support plate for connection and support, a power source for providing driving force, a transmission component for power transmission, and a translation block that is driven to move; the specific structure is a mechanical structure in the prior art that can convert rotational motion into linear motion, which is common knowledge in the field. Therefore, this application will not explain the control method and structure in detail, and will not elaborate on them here.
[0039] In some embodiments, the limiting component includes: a slide rail 7 fixed to one side of the X-axis frame 1, the top of the Y-axis frame 11, and one side of the Z-axis frame 12, respectively, and a limiting block 71 fixed to the bottom of the X-axis frame 1, one side of the Z-axis frame 12, and one side of the mounting box 2, respectively; one side of the limiting block 71 is slidably connected to one side of the slide rail 7.
[0040] It should be noted that by using a limit assembly consisting of a slide rail 7 and a limit block 71, the travel of the X-axis frame 1, Z-axis frame 12 and mounting box 2 is limited by the sliding connection between the slide rail 7 and the limit block 71, ensuring that they move stably within a predetermined range and avoiding damage or malfunction caused by exceeding the range.
[0041] In use, this invention utilizes a three-dimensional moving frame comprised of an X-axis frame 1, a Y-axis frame 11, and a Z-axis frame 12, along with translation and limiting components, to achieve precise movement of the transfer pitch-changing mechanism in the X, Y, and Z directions. The transfer pitch-changing mechanism is mounted on one side of the Z-axis frame 12 via a mounting box 2. The bottom of the internal fixing block 3 has several transfer plates 31, with negative pressure suction cups 32 evenly distributed on the bottom of each transfer plate 31 for adsorbing buttons. A slider 34 is located at the top of each transfer plate 31, slidingly connected to a linear guide rail 33 at the bottom of the fixing block 3 to ensure stable movement of the transfer plate 31. A power mechanism drives the transfer plates 31 on both sides to move synchronously closer or further apart, transmitting power through a transmission component to achieve the pitch-changing function. A spacing maintenance component ensures consistent spacing between adjacent transfer plates 31. A negative pressure device is connected to the gas flow channel inside the transfer plate 31 via a pipeline, generating negative pressure adsorption force to adsorb the buttons. In the planar direction, the translation components of the X-axis frame 1 and Y-axis frame 11 are perpendicularly arranged, and in the vertical direction, the translation components of the X-axis frame 1 and Z-axis frame 12 are perpendicularly arranged to ensure precise movement. The limiting component consists of a slide rail 7 and a limiting block 71, which limits the range of movement and ensures stability. This design allows for adaptation to buttons of different sizes, improving the efficiency and automation level of material loading and transfer.
