[0036] Example:

[0037] like Figure 1-7 As shown, this embodiment proposes a trolley mechanism, including a base 1, a support rod 2 fixedly mounted on the base 1, and an abnormal storage frame 3 fixedly mounted on the top of the support rod 2, which can store abnormal PCB boards in batches; a temporary storage rack 4 fixedly mounted on the support rod 2, and infeed / outfeed guide pulleys 5 rotatably connected to the support rod 2, guiding the carrier basket into the temporary storage rack 4 after it is guided by the infeed / outfeed guide pulleys 5; a positioning component 6 is also fixedly mounted on the support rod 2, and after the basket enters the corresponding temporary storage rack 4, the positioning component 6 is used to place the carrier basket in a suitable position; two self-resetting casters 7 and brake casters 8 are fixedly mounted on the bottom of the base 1, respectively, and the trolley is pushed to the desired workstation by pulling the self-resetting casters 7, and then used after being in place. Brake casters 8 are locked; auxiliary blocks 9 are fixedly installed on both the front and back of the abnormal storage frame 3, and baffles 10 are rotatably connected to the auxiliary blocks 9. The baffles 10 can prevent objects placed on the temporary storage rack 4 from slipping off; a sliding groove 21 is opened on the auxiliary blocks 9, and a self-locking mechanism is set in the sliding groove 21 to lock the baffles 10; a vertical plate 11 is fixedly installed on the base 1, and a connecting seat 12 is fixedly installed on the vertical plate 11. A rubber pad 27 is glued to the front of the connecting seat 12, which can reduce the impact force after the front of the trolley is hit when pushing a single trolley; an auxiliary plate 15 is fixedly installed on the base 1, and a connecting mechanism is set on the auxiliary plate 15. Multiple trolleys can be connected together through the connecting mechanism, so that multiple trolleys can be pulled at one time, which helps to improve work efficiency.

[0038] The self-locking mechanism includes a trapezoidal insert 22 slidably connected in the slide groove 21. A slide rod 23 is fixedly installed on the top of the trapezoidal insert 22. The slide rod 23 drives the trapezoidal insert 22. A pull plate 24 is fixedly installed on the top of the slide rod 23. The pull plate 24 drives the slide rod 23. A spring 25 is sleeved on the outer wall of the slide rod 23. One end of the spring 25 is fixedly connected to the inner wall of the slide groove 21, and the other end of the spring 25 is fixedly connected to the trapezoidal insert 22.

[0039] A connecting groove 13 is provided on the connecting seat 12, and a fixing bolt 14 is threadedly connected to the top of the connecting seat 12. The connecting block 17 is fixed to the connecting seat 12 using the fixing bolt 14.

[0040] The connecting mechanism includes a rotating plate 16 rotatably connected to an auxiliary plate 15, and a connecting block 17 is fixedly installed on the rotating plate 16. The connecting block 17 is adapted to the connecting groove 13. The connecting block 17 on one of the trolleys is inserted into the connecting seat 12 on the other trolley, so that the connecting block 17 is inserted into the connecting groove 13.

[0041] A locking bolt 19 is screwed onto the auxiliary plate 15. When the connecting block 17 is not in use, it is fixed to the placement plate 15 by the locking bolt 19.

[0042] A slot 26 is provided on the top of the baffle 10, and the slot 26 cooperates with the trapezoidal plug 22.

[0043] A handle 20 is fixedly installed on the base 1, and the trolley is pulled by the handle 20.

[0044] Specifically, when using this trolley mechanism: the carrier basket is guided by the infeed and outfeed guide pulleys 5 and then enters the temporary storage rack 4. After the basket enters the corresponding temporary storage rack 4, the positioning component 6 is used to place the carrier basket in the appropriate position, thus completing the placement of the carrier basket; the abnormal storage box 3 can store abnormal PCB boards in batches.

[0045] After placing the vehicle basket, rotate the baffle 10 to block the vehicle basket. At this time, the self-locking mechanism will fix the baffle 10. When you need to remove the vehicle basket, first pull the pull plate 24. The pull plate 24 drives the sliding rod 23, and the sliding rod 23 drives the trapezoidal insert 22, so that the trapezoidal insert 22 disengages from the slot 26. Then rotate the baffle 10 so that it does not block the vehicle basket, and the vehicle basket can be removed.

[0046] When multiple trolleys need to be pulled, insert the connecting block 17 on one trolley into the connecting seat 12 on another trolley, so that the connecting block 17 is inserted into the connecting groove 13, and then use the fixing bolt 14 to fix the connecting block 17 on the connecting seat 12. At this time, multiple trolleys can be pulled at one time, which helps to improve work efficiency.

[0047] Pull the trolley to the desired work position via the self-resetting caster 7, and lock it in place using the brake caster 8.

[0048] All technical features in this embodiment can be freely combined according to actual needs.

[0049] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
