With the continuous development of industrial technology and the increasing diversification of production requirements, higher requirements are put forward for the performance of the variable pitch mechanism. In the prior art, the variable pitch mechanism usually changes the output motion distance by adjusting the relative position or shape of the mechanism components to meet the motion requirements under different working conditions.

[0015] Beneficial effects:

[0016] The present invention provides an adjustable-spacing device. A driver and a fixing block are respectively arranged on a support base. A guiding assembly is connected to the fixing block. A first adjusting member in an adjusting mechanism is slidably arranged on the guiding assembly. The first adjusting member is connected to the driver. A second adjusting member is slidably arranged on the guiding assembly. A first adsorption assembly is connected to the first adjusting member. A second adsorption assembly is connected to the second adjusting member. A first limiting member is fixedly connected to the first adjusting member. A protruding portion of the second adjusting member is embedded inside a first limiting groove of the first limiting member. The first adjusting member, the first limiting member, and the second adjusting member move synchronously along the length extension direction of the guiding assembly. In this way, after the driver is started, the linear motion is transmitted to the first limiting member through the sliding cooperation between the first adjusting member and the guiding assembly. Due to the radial constraint of the first limiting groove of the first limiting member on the protruding portion, the second adjusting member will be forced to move in linkage. Under the guiding action of the guiding assembly, the first adjusting member and the second adjusting member will move along the length extension direction of the guiding assembly. The displacement amount between the first adjusting member and the second adjusting member is controlled by the length of the first limiting groove and the cooperation with the protruding portion. During the motion transmission process, two opposite inner walls of the first limiting groove can respectively abut against the protruding portion, so that the protruding portion moves inside the first limiting groove, limiting the moving range of the protruding portion. At the same time, the straightness constraint of the guiding assembly improves the smoothness of the motion, which is beneficial to improving the accuracy of the spacing adjustment between the first adsorption assembly and the second adsorption assembly. Thus, the technical effects of improving the adjustment accuracy and enhancing the efficiency are achieved. Description of the drawings

Figure 6 FIG. is a schematic structural diagram of a first bearing and a second bearing in an adjustable-spacing device provided in an embodiment of the present invention. Figure 7 FIG. is a schematic structural diagram of a first limiting member in an adjustable-spacing device provided in an embodiment of the present invention. Figure 8It is a schematic structural diagram of a second adjusting member in a device with adjustable spacing provided by an embodiment of the present invention. A device with adjustable spacing provided by an embodiment of the present invention includes a support base 1, a driver 2, a fixed block 3, a guiding assembly 4 and an adjusting mechanism 5. The driver 2 and the fixed block 3 are respectively arranged on the support base 1. The guiding assembly 4 is connected to the fixed block 3. The adjusting mechanism 5 includes a first adjusting member 51, a second adjusting member 52, a first adsorption assembly 53, a second adsorption assembly 54 and a first limiting member 55. The first adjusting member 51 is slidably arranged on the guiding assembly 4, and the first adjusting member 51 is connected to the driver 2. The second adjusting member 52 is slidably arranged on the guiding assembly 4. The second adjusting member 52 has a protruding portion 521. The first adsorption assembly 53 is connected to the first adjusting member 51. The second adsorption assembly 54 is connected to the second adjusting member 52. The first limiting member 55 has a first limiting groove 551. The first limiting member 55 is fixedly connected to the first adjusting member 51. At least a part of the protruding portion 521 is located inside the first limiting groove 551. The driver 2 drives the first adjusting member 51 to move along the length extension direction of the guiding assembly 4, so as to push the first limiting member 55 to pull the protruding portion 521 and the second adjusting member 52 to move, so that the first adjusting member 51, the first limiting member 55 and the second adjusting member 52 move synchronously along the length extension direction of the guiding assembly 4, so as to drive the first adsorption assembly 53 and the second adsorption assembly 54 to move respectively.

[0035] Wherein, the first limiting member 55 is fixedly connected to the side surface of the first adjusting member 51. The first limiting member 55 is provided with a strip-shaped first limiting groove 551 penetrating through its length. The groove width of the first limiting groove 551 can be slightly larger than the width of the protruding portion 521 of the second adjusting member 52. The groove width of the first limiting groove 551 can refer to the spacing between the two inner walls of the first limiting groove 551, so that the protruding portion 521 can move inside the first limiting groove 551.

[0036] Wherein, the driver 2 includes a motor or a cylinder. After the driver 2 is started, it can drive the first adjusting member 51 to move along the straight line direction of the guiding assembly 4. Through the cooperation of the first limiting groove 551 of the first limiting member 55 and the protruding portion 521, the second adjusting member 52 will be forced to move synchronously or differentially, so as to dynamically adjust the spacing between the first adsorption assembly 53 and the second adsorption assembly 54.

[0037] In this embodiment, the driver 2 and the fixing block 3 are respectively arranged on the support base 1. The guiding component 4 is connected to the fixing block 3. The first adjusting member 51 in the adjusting mechanism 5 is slidably arranged on the guiding component 4. The first adjusting member 51 is connected to the driver 2. The second adjusting member 52 is slidably arranged on the guiding component 4. The first adsorption component 53 is connected to the first adjusting member 51. The second adsorption component 54 is connected to the second adjusting member 52. The first limiting member 55 is fixedly connected to the first adjusting member 51. The protruding portion 521 of the second adjusting member 52 is embedded inside the first limiting groove 551 of the first limiting member 55. The first adjusting member 51, the first limiting member 55, and the second adjusting member 52 move synchronously along the length extension direction of the guiding component 4. After the driver 2 is started, through the sliding fit between the first adjusting member 51 and the guiding component 4, the linear motion is transmitted to the first limiting member 55. Due to the radial constraint of the first limiting groove 551 of the first limiting member 55 on the protruding portion 521, the second adjusting member 52 will be forced to move in linkage. Under the guiding action of the guiding component 4, the first adjusting member 51 and the second adjusting member 52 will move along the length extension direction of the guiding component 4. The displacement amount between the first adjusting member 51 and the second adjusting member 52 is controlled by the length of the first limiting groove 551 and the fit with the protruding portion 521. During the motion transmission process, the two opposing inner walls of the first limiting groove 551 can respectively abut against the protruding portion 521, enabling the protruding portion 521 to move inside the first limiting groove 551, limiting the movement range of the protruding portion 521. At the same time, the straightness constraint of the guiding component 4 improves the smoothness of the motion, which is beneficial to improving the accuracy of the spacing adjustment between the first adsorption component 53 and the second adsorption component 54. Thus, the technical effects of improving the adjustment accuracy and enhancing the efficiency are achieved.

[0038] As an implementation manner, the support base 1 includes a mounting block 11, a base 12, and a connecting block 13. The mounting block 11 has a mounting hole 111. The base 12 is connected to the mounting block 11. The base 12 has a through groove 121. The driver 2 is connected to the base 12. One end of the connecting block 13 is connected to the push rod of the driver 2. The other end of the connecting block 13 passes through the through groove 121 and is connected to the first adjusting member 51. The thrust of the driver 2 is directly transmitted to the first adjusting member 51 through the connecting block 13. The through groove 121 can also limit the radial displacement of the connecting block 13, enabling the driving force to be transmitted along the linear direction of the guiding component 4, reducing the movement deviation of the first adjusting member 51. At the same time, the straightness constraint of the guiding component 4 is beneficial to improving the accuracy of the spacing adjustment between the first adsorption component 53 and the second adsorption component 54.

[0039] In some embodiments, the first adjusting member 51 includes a first slider 511 and a first through hole 512. The first through hole 512 is provided in the first slider 511. The first slider 511 is connected to the other end of the connecting block 13. The guiding assembly 4 passes through the first through hole 512, and the first slider 511 is connected to the first adsorption assembly 53. The first through hole 512 and the guiding assembly 4 can be in clearance fit to reduce the frictional resistance and improve the response speed of the first adjusting member 51. Driven by the driver 2, the first slider 511 drives the first adsorption assembly 53 to move smoothly along the guiding assembly 4.

[0040] In some embodiments, the number of the second adjusting members 52 is plural, and the number of the second adsorption assemblies 54 is plural. The plural second adjusting members 52 are arranged along the length extension direction of the guiding assembly 4, and the second adsorption assemblies 54 are arranged in one-to-one correspondence with the second adjusting members 52. The plural second adsorption assemblies 54 can simultaneously adsorb and position the plural products 6. By the movement of the first adjusting member 51 to link all the second adjusting members 52, synchronous pitch adjustment of multiple workstations is achieved.

[0041] In some embodiments, the adjusting mechanism 5 further includes a second limiting member 56. One second limiting member 56 is provided between two adjacent second adjusting members 52. The second limiting member 56 has a second limiting groove 561. Along the length extension direction of the guiding assembly 4, the length of the second limiting groove 561 is the same as the length of the first limiting groove 551. The second adjusting member 52 includes a second slider 522 and a second through hole 523. The second through hole 523 is provided in the second slider 522. The second slider 522 is connected to the second adsorption assembly 54. The guiding assembly 4 passes through the second through hole 523. The convex portion 521 provided on the second slider 522 is at least partially located inside the corresponding second limiting groove 561, wherein the convex portion 521 adjacent to the first adjusting member 51 is at least partially located inside the first limiting groove 551. The second limiting member 56 prevents overshoot or hysteresis during multi-station adjustment by restricting the relative displacement amount of the second adjusting member 52. When the first adjusting member 51 moves, it will drive the second adjusting member 52 to move, and the second adjusting member 52 can also achieve differential adjustment due to the constraint of the second limiting member 56.

[0042] In some embodiments, in a device with adjustable spacing provided by Embodiment 1 of the present invention, the adjusting mechanism 5 further includes a first bearing 57 and a second bearing 58. The first bearing 57 and the second bearing 58 are respectively slidably connected to the guiding assembly 4. The first bearing 57 is fixedly connected to the first adjusting member 51, and the second bearing 58 is fixedly connected to the second adjusting member 52. The guiding assembly 4 is respectively in sliding fit with the first bearing 57 and the second bearing 58. The length extension direction of the guiding assembly 4 is parallel to the driving direction of the driver 2. The first bearing 57 and the second bearing 58 are beneficial to reducing the moving resistance of the first adjusting member 51 and the second adjusting member 52. Under the same output force of the driver 2, the response speed is increased, and the wear amount is also reduced after long-term operation, thus prolonging the service life.

[0043] In some embodiments, in a device with adjustable spacing provided by Embodiment 1 of the present invention, the guiding assembly 4 includes two guiding shafts 41. The two guiding shafts 41 are respectively connected to the fixed block 3. The first adjusting member 51 and the second adjusting member 52 are respectively sleeved outside the two guiding shafts 41, and the first adjusting member 51 and the second adjusting member 52 are respectively in sliding fit with the two guiding shafts 41, that is, the two guiding shafts 41 sequentially penetrate through the first adjusting member 51 and the second adjusting member 52, and the two guiding shafts 41 are parallel to each other. Through the two guiding shafts 41, the moving trajectories of the first adjusting member 51 and the second adjusting member 52 can be doubly constrained. When the driver 2 pushes the first adjusting member 51 to move, it is beneficial to improve the parallelism error of the displacement plane between the first adsorption assembly 53 and the second adsorption assembly 54, and enhance the consistency of multi-station spacing adjustment.

[0044] In some embodiments, the first adsorption assembly 53 includes a first support block 531, a first column 532, and a first adsorption nozzle 533. The first support block 531 is connected to the first adjusting member 51. One first column 532 and two first adsorption nozzles 533 are respectively connected to the first support block 531, and the first column 532 is located between the two first adsorption nozzles 533. The second adsorption assembly 54 includes a second support block 541, a second column 542, and a second adsorption nozzle 543. The second support block 541 is connected to the second adjusting member 52. One second column 542 and two second adsorption nozzles 543 are respectively connected to the second support block 541, and the second column 542 is located between the two second adsorption nozzles 543. The first column 532 and the second column 542 are aligned with each other. The first adsorption nozzle 533 on one side of the first column 532 is aligned with the second adsorption nozzle 543 on one side of the second column 542, and the first adsorption nozzle 533 on the other side of the first column 532 is aligned with the second adsorption nozzle 543 on the other side of the second column 542. The first column 532 and the second column 542 can serve as positioning references, so that the first adsorption nozzles 533 on both sides of the first column 532 and the second adsorption nozzles 543 on both sides of the second column 542 maintain a symmetric distribution during movement. When the first adjusting member 51 moves, all the first adsorption nozzles 533 and the second adsorption nozzles 543 will move respectively, so that the spacing between the first adsorption nozzle 533 and the second adsorption nozzle 543 on the same straight line and the spacing between adjacent second adsorption nozzles 543 are adjusted to the same spacing, which is beneficial for application in precision assembly scenarios.

[0045] To illustrate in detail a method with adjustable spacing provided by the present invention, the above-mentioned Embodiment 1 has described in detail a device with adjustable spacing. Based on the same inventive concept, the present application also provides a method with adjustable spacing, as shown in Embodiment 2 for details.

[0046] Please refer to Figure 9 , Figure 9 which is a flowchart of a method with adjustable spacing provided by an embodiment of the present invention. Embodiment 2 of the present invention provides a method with adjustable spacing, including the above-mentioned device with adjustable spacing, and further includes the following steps:

[0047] Step S100, using the driver 2 to drive the first slider 511 of the first adjusting member 51 to move along the length extension direction of the guiding assembly 4;

[0048] Step S200, through the cooperation between the first limiting groove 551 of the first limiting member 55 fixed to the first slider 511 and the protruding portion 521 of the second slider 522 of the second adjusting member 52, driving the second slider 522 to move along the length extension direction of the guiding assembly 4 following the moving first slider 511;

[0049] Step S300: Through the linkage between the second limiting grooves 561 of the second limiting members 56 between adjacent second sliders 522 and the corresponding protruding portions 521, the displacement of the first slider 511 is sequentially transmitted to a plurality of the second sliders 522, so that the distances between the first slider 511 and all the second sliders 522 are adjusted to be equal.

[0050] Specifically, after the driver 2 is started, the first slider 511 moves along the guide shaft 41. The first limiting groove 551 of the first limiting member 55 drives the protruding portion 521 of the second slider 522 to move. The second limiting grooves 561 of the second limiting members 56 between adjacent second sliders 522 are linked, so that the displacement amounts of the plurality of second sliders 522 are all equal to the displacement amount of the first slider 511, realizing the adjustment of the distances between the first suction nozzle 533 and the second suction nozzle 543 located on the same straight line and the distances between adjacent second suction nozzles 543 to the same distance.

[0051] As an implementation manner, Embodiment 2 of the present invention provides a method for adjustable distance, which further includes fixing or releasing the product through the first suction assembly 53 connected to the first slider 511 and the second suction assembly 54 connected to the second slider 522. The length of the second limiting groove 561 is the same as the length of the first limiting groove 551, so that the distance increments during the displacement transmission are evenly distributed. When the first slider 511 moves, the protruding portion 521 can slide in the corresponding second limiting groove 561, driving a plurality of second sliders 522 to move sequentially. The equal-length second limiting groove 561 and first limiting groove 551 will realize the linear relationship of the displacement transmission, avoid the distortion of the displacement ratio, and effectively solve the situation that the distances are different after the product 6 is cut.

[0052] The present invention provides a method for adjustable spacing. By using a driver 2 to drive a first slider 511 of a first adjusting member 51 to move along the length extension direction of a guiding assembly 4, through the cooperation between a first limiting groove 551 of a first limiting member 55 fixed to the first slider 511 and a protruding portion 521 of a second slider 522 of a second adjusting member 52, the second slider 522 is driven to move along the length extension direction of the guiding assembly 4 following the moving first slider 511. Through the linkage between a second limiting groove 561 of a second limiting member 56 between adjacent second sliders 522 and the corresponding protruding portion 521, the displacement of the first slider 511 is sequentially transmitted to a plurality of the second sliders 522, so that the spacing between the first slider 511 and all the second sliders 522 is adjusted to an equal spacing. In this way, after the driver 2 is started, through the sliding cooperation between the first adjusting member 51 and the guiding assembly 4, the linear motion is transmitted to the first limiting member 55. Due to the radial constraint of the first limiting groove 551 of the first limiting member 55 on the protruding portion 521, the second adjusting member 52 will be forced to be linked. Under the guiding action of the guiding assembly 4, the first adjusting member 51 and the second adjusting member 52 will move along the length extension direction of the guiding assembly 4, and the displacement amount between the first adjusting member 51 and the second adjusting member 52 is controlled by the length of the first limiting groove 551 and its cooperation with the protruding portion 521. During the motion transmission process, two opposing inner walls of the first limiting groove 551 can respectively abut against the protruding portion 521, enabling the protruding portion 521 to move inside the first limiting groove 551, limiting the moving range of the protruding portion 521, and at the same time improving the smoothness of the motion by the straightness constraint of the guiding assembly 4, which is beneficial to improving the accuracy of the spacing adjustment between the first adsorption assembly 53 and the second adsorption assembly 54. Thus, the technical effects of improving the adjustment accuracy and enhancing the efficiency are achieved.
