[0002] In the industrial field, the interval between different stations is usually adjusted. The traditional interval adjustment mechanism is generally divided into fixed interval adjustment mechanism, stepped interval adjustment mechanism and stepless interval adjustment mechanism. The fixed interval adjustment mechanism can only adjust the interval of one distance. The stepped interval adjustment mechanism can adjust the interval of multiple discrete data distances.

[0003] However, the interval between stations during processing is currently diversified, especially for equipment with high processing precision requirements. Multiple interval adjustment methods need to be combined to achieve high-precision processing during workpiece processing, such as electronic component assembly, part arrangement, etc. Accurate interval adjustment of workpieces is often required.

[0038] Reference Figures 1 to 4 , the utility model embodiment provides a variable distance device.

[0039] Specifically, as shown in the figure, the moving module 100 includes a first mounting base 120, a first driving member (not shown), and a first transmission member 110. The first transmission member 110 is preferably a lead screw. The first transmission member 110 is rotatably connected to a lead screw seat 150 on the first mounting base 120, while the first driving member is disposed at either end of the first transmission member 110. The output end of the first driving member is connected to the first transmission member 110, and the first driving member drives the first transmission member 110 to rotate.

[0040] The pitch module 200 includes a second mounting base 240, a second driving member 210, a second transmission member 220, and a third transmission member 230. As shown in the figure, the second mounting base 240 is mounted on the first mounting base 120 and slidably connected to the first mounting base 120, while the second driving member 210, the second transmission member 220, and the third transmission member 230 are sequentially connected in a transmission manner. At the same time, the third transmission member 230 is also connected in a transmission manner to the first transmission member 110.

[0041] Optionally, multiple split modules 200 can be installed on the mobile module.

[0042] Furthermore, such as Figure 3 As shown, the third transmission component 230 is hollow to form a transmission cavity that can be connected to the first transmission component 110. The inner wall of the transmission cavity is provided with an internal thread that matches and connects with the first transmission component 110. That is, it can be understood that the third transmission component 230 and the first transmission component 110 are a lead screw transmission structure. When the lead screw rotates, the third transmission component 230 can move precisely linearly along the axis of the lead screw, thereby driving all the pitch modules 200 on the moving module 100 to move simultaneously. Moreover, the distance between adjacent pitch modules 200 remains unchanged during the movement, achieving constant pitch variation.

[0043] Furthermore, the second transmission component 220 is preferably a gear, and the third transmission component 230 is provided with an external gear ring that meshes with the gear. Through gear transmission, the rotation angle of the third transmission component 230 can be precisely controlled, further ensuring the processing accuracy of the product. When the second drive component 210 drives the second transmission component 220 to rotate, thereby driving the third transmission component 230 to rotate, the third transmission component 230 and the lead screw will generate a threaded transmission. At this time, the third transmission component 230 can drive the pitch module 200 to adjust its position on the moving module 100, adjusting the spacing between the pitch modules 200 according to processing requirements to achieve stepless variable pitch. The spacing between the pitch modules 200 is designed according to actual needs.

[0044] It can be understood that the distance separation module 200 is first started, linearly moves on the moving module 100, and moves to a preset position on the moving module 100 to realize the specific position adjustment of the distance separation module 200 on the moving module 100, so as to achieve the effect of stepless variable distance. When the distance between the distance separation modules 200 is determined, the moving module 100 drives the distance separation module 200 to linearly move a preset distance, and drives the distance separation module 200 to the corresponding processing station, so as to achieve the effect of fixed variable distance. That is, the distance between the distance separation modules 200 is first determined, and then the moving distance of the distance separation module 200 relative to the position of the processing station is determined.

[0045] Of course, in actual application, the moving module 100 can first drive the distance separation module 200 to linearly move a preset distance, and then the distance separation module 200 is started, linearly moves on the moving module 100, and moves to a preset position on the moving module 100 to realize the specific position adjustment of the distance separation module 200 on the moving module 100, so that the workpiece or jig on the distance separation module 200 corresponds to the processing station.

[0046] Similarly, when the distance between the processing stations changes, the distance separation module 200 can adjust the position according to the changed distance between the processing stations.

[0047] By combining stepless variable distance and fixed variable distance, the high-precision processing requirement of the workpiece is met, which helps to improve the processing precision of the product and meets the diversified variable distance requirement in automatic processing.

[0048] It should be noted that, in order to ensure the accuracy of the distance adjustment, when the third transmission member 230 drives the distance separation module 200 to adjust the position on the moving module 100, the first driving member (not shown in the figure) is in an energized state at this time, but the first driving member (not shown in the figure) is not started, and the first driving member (not shown in the figure) in the energized state can lock the first transmission member 110 to prevent the first transmission member 110 from rotating and affecting the accuracy of the distance adjustment between the distance separation modules 200.

[0049] Further, the two second transmission members 220 are synchronously rotated through the transmission shaft 250. The synchronous transmission of the two second transmission members 220 improves the stability and reliability of the transmission.

[0050] Further, the third transmission member 230 is provided with a blocking portion 231 at both ends, and the blocking portion 231 is movably abutted with the second transmission member 220 arranged on the same side. The design of the blocking portion 231 can prevent the third transmission member 230 from axially moving during rotation, thereby improving the accuracy and stability of the transmission.

[0051] According to some embodiments of the present application, the second mounting base 240 is slidably connected with the first mounting base 120. Optionally, the first mounting base 120 and the second mounting base 240 are slidably connected through a guide mechanism.

[0052] Specifically, the guide mechanism comprises a guide rail 130 and a sliding block 140, the guide rail 130 is fixed on the first mounting base 120, the sliding block 140 is slidably connected with the guide rail 130, and the second mounting base 240 is fixedly connected with the sliding block 140. Through the guide mechanism, the pitch changing module 200 can freely slide on the moving module 100, further improving the flexibility and precision of pitch changing, and improving the stability and precision of sliding.

[0053] According to some embodiments of the present application, the second mounting base 240 is provided with a wire outlet hole 241, the wire outlet hole 241 is provided on the same side of the second driving member 210, and is used for the power supply wire of the second driving member 210 to pass out to the outside of the second mounting base 240, facilitating the arrangement and management of the power supply wire.

[0054] In addition, the present application also provides a processing equipment (not shown in the figure) using the above-mentioned pitch changing device, wherein the jig is fixed on the second mounting base 240 of the pitch changing module 200. A plurality of pitch changing modules 200 are arranged along the axis direction of the first driving member 110, and a plurality of workpieces can be simultaneously pitch changed, improving the processing efficiency.
