Description

Technical Field

[0001] This utility model relates to the field of automated conveying technology, and in particular to a return conveying line. Background Technology

[0002] In the field of automated production, return conveyor lines are key equipment for enabling the transfer of workpieces between various processes. Their operating efficiency and stability directly affect production progress and product quality. However, existing return conveyor lines have several shortcomings: First, when fixtures turn between the transverse and longitudinal conveyor lines, mismatched guide structures often lead to poor docking and jamming, severely impacting transfer efficiency. Second, fixture positioning accuracy is low, with significant positional deviations at each station, increasing the error rate in subsequent processing or assembly steps. Third, during transport, vibrations or start-stop impacts from the conveyor line can easily damage workpieces on the fixtures, increasing production costs. Fourth, the stability of the drive mechanism's cooperation with the fixtures is insufficient, easily causing power transmission interruptions and affecting the continuity of transport. Therefore, designing a return conveyor line that can solve the above problems is of great significance. Utility Model Content

[0023] like Figure 1 As shown, in an exemplary embodiment of this utility model, the longitudinal conveyor line is composed of a longitudinal guide module 11, a longitudinal drive module 12 and a fixture positioning mechanism 13, with the longitudinal guide module 11 and the longitudinal drive module 12 arranged parallel to each other at longitudinal intervals. The longitudinal guide module 11 uses a guide rail to guide the fixture seat 100 to slide longitudinally. The longitudinal drive module 12 consists of a mounting side plate 121, a synchronous toothed belt 122, a drive motor 123, a drive pulley 124, and multiple sets of driven pulleys 125. The drive motor 123 is fixed on the mounting side plate 121 and drives the drive pulley 124 to rotate. The multiple sets of driven pulleys 125 are rotated on the mounting side plate 121. The synchronous toothed belt 122 is wound around the drive pulley 124 and the multiple sets of driven pulleys 125. The synchronous toothed belt 122 is arranged parallel to the guide rail along the longitudinal direction and matches the rack 200 on the bottom side of the fixture seat 100 base to drive the fixture seat 100. The fixture positioning mechanism 13 is used to position the fixture seat 100 to ensure its accurate position on the workstation.

[0024] like Figure 1 As shown, in an exemplary embodiment of this utility model, the transverse conveyor line consists of a transverse guide module 21, a transverse drive module 22, and a transfer guide module 23. The transverse guide module and the transverse drive module are arranged parallel to each other at transverse intervals. The transverse guide module 21 uses a second guide rail to guide the transfer guide module 23 to slide laterally. The transverse drive module 22 uses a rodless cylinder and is arranged parallel to the second guide rail at transverse intervals to drive the transfer guide module 23 to move. The transfer guide module 23 consists of a slide block 231, a third guide rail 232, and a limiting block 233. The slide block 231 slides on the second guide rail and is driven by the rodless cylinder. The third guide rail 232 is fixed longitudinally on the slide block 231 and can dock with the first guide rail to receive or transport the slider of the fixture seat 100. The limiting block 233 is fixed on the slide block 231 and located at the outer end of the third guide rail 232 to prevent the fixture seat 100 from slipping.

[0025] like Figure 1As shown, in an exemplary embodiment of this utility model, the fixture base 100 comprises a slider 101, a base 102, a floating plate 103, and a fixture 104. The base 102 is fixedly mounted on the slider 101, the floating plate 103 is mounted on the base 102 via a floating assembly, and the fixture 104 is mounted on the floating plate 103. The base 102 is provided with a positioning hole 1021 for positioning in conjunction with the fixture positioning mechanism 13. The floating assembly includes multiple sets of guide posts and rectangular springs. The guide posts are vertically arranged on the bottom side of the floating plate 103 and their top ends are fixedly connected to the floating plate 103. The base 102 is provided with guide sleeves that correspond to and match the guide posts. The guide posts slide in the guide sleeves, and the bottom end of the guide posts is provided with a stop block. The rectangular springs are sleeved on the guide posts, with one end abutting against the bottom side of the floating plate 103 and the other end abutting against the top side of the base 102, thus providing a buffering and shock-absorbing effect.

[0026] During operation, the fixture seat 100 is driven by the synchronous toothed belt 122 of the longitudinal drive module 12 meshing with the rack 200 on the longitudinal conveyor line, and slides along the guide rail 1 of the longitudinal guide module 11. When it reaches a specific workstation, the fixture positioning mechanism 13 inserts into the positioning hole 1021 to achieve positioning. When it reaches the docking position with the transverse conveyor line, the longitudinal drive module 12 drives the fixture seat 100 to transfer to the guide rail 3 232. Then, the rodless cylinder of the transverse conveyor line drives the fixture seat 100 to move along the guide rail 2, so that the guide rail 3 232 docks with the guide rail 1 on the other side. The slider of the fixture seat 100 is then driven by the longitudinal drive module 12 on the other side to transfer to the corresponding guide rail 1, completing the transfer and realizing rectangular return.
