[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] An upper and lower double-track independently driven variable-distance mechanism comprises a support frame, on which a first servo motor, a second servo motor, an upper annular guide rail and a lower annular guide rail are arranged, and an upper connecting slide group and a lower connecting slide group are installed on the upper annular guide rail and the lower annular guide rail, the first servo motor is connected to the upper connecting slide group through an upper drive chain, and the second servo motor is connected to the lower connecting slide group through a lower drive chain.

[0006] Preferably, the first servo motor is drivingly connected to the upper drive chain via an upper drive sprocket, and the second servo motor is drivingly connected to the lower drive chain via a lower drive sprocket.

[0007] Preferably, the upper end of the upper connecting slide assembly is connected to the upper driving chain through an upper connecting plate, and the bottom of the lower connecting slide assembly is connected to the lower driving chain through a lower connecting plate.

[0008] Preferably, the upper connecting slide assembly is slidably connected to the upper annular guide rail and the lower annular guide rail respectively through sliding wheels.

[0009] Preferably, the lower connecting slide assembly is slidably connected to the upper annular guide rail and the lower annular guide rail respectively through sliding wheels.

[0010] By adopting the above technical scheme, the utility model provides an upper and lower double-track independently driven variable-distance mechanism, which has the following beneficial effects: an upper connecting slide group and a lower connecting slide group are installed on the upper annular guide rail and the lower annular guide rail in the upper and lower double-track independently driven variable-distance mechanism, the first servo motor is connected to the upper connecting slide group through an upper driving chain, and the second servo motor is connected to the lower connecting slide group through a lower driving chain. By arranging the first servo motor and the second servo motor to drive the upper connecting slide group and the lower connecting slide group respectively, independent control of the corresponding upper connecting slide group and the lower connecting slide group is achieved, so that the spacing between the upper connecting slide group and the lower connecting slide group can be adjusted according to actual production needs, effectively solving the defect that the spacing of the chain drive type or the belt drive type is constant, and the clamping of the product carrier can be quickly realized, with high flexibility and able to meet production needs.

[0016] like Figure 1 As shown, the upper and lower double-track independently driven variable pitch mechanism includes a support frame 1, on which a first servo motor 2, a second servo motor 3, an upper annular guide rail 4 and a lower annular guide rail 5 are arranged, and an upper connecting slide group 6 and a lower connecting slide group 7 are installed on the upper annular guide rail 4 and the lower annular guide rail 5, the first servo motor 2 is transmission-connected to the upper connecting slide group 6 through an upper drive chain 8, and the second servo motor 3 is transmission-connected to the lower connecting slide group 7 through a lower drive chain 9. It can be understood that the structure of the upper and lower double-track independently driven variable pitch mechanism consists of: two independently driven servo motors, upper and lower closed-loop annular guide rails, upper and lower drive sprocket groups, upper and lower transmission chains, upper and lower connecting slide groups and an integral support frame, that is, the upper and lower layers are independent circulation systems, and the variable pitch function is achieved by independently driving the transmission components through the servo motors.

[0017] Specifically, the first servo motor 2 is connected to the upper drive chain 8 through the upper drive sprocket 10, and the second servo motor 3 is connected to the lower drive chain 9 through the lower drive sprocket 11; the upper end of the upper connecting slide group 6 is connected to the upper drive chain 8 through the upper connecting plate 12, and the bottom of the lower connecting slide group 7 is connected to the lower drive chain 9 through the lower connecting plate 13; the upper connecting slide group 6 is slidably connected to the upper annular guide rail 4 and the lower annular guide rail 5 through the sliding wheel 14; the lower connecting slide group 7 is slidably connected to the upper annular guide rail 4 and the lower annular guide rail 5 through the sliding wheel 14.

The first servo drive motor 2 controls the upper drive chain 8 to drive the upper connecting slide group 6, and the second servo drive motor 2 controls the lower drive chain 9 to drive the lower connecting slide group 7. The upper and lower drive sprockets do not interfere with each other during transmission, and the distance between the slides can be defined according to product requirements.
