[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown: A transfer trolley for automotive welding includes a base 2 and a gravity-limiting support mechanism 5;

[0022] The base 2 is equipped with several gravity-limiting support mechanisms 5;

[0023] The gravity-limiting support mechanism 5 includes columns 8, L-shaped flip plates 9, and limiting blocks. Two columns 8 are mounted on the base 2, and several limiting blocks are arranged between the front and rear of the two columns 8. An L-shaped flip plate 9 is rotatably mounted between the two columns 8 and between the two limiting blocks. In this embodiment, there are four sets of gravity-limiting support mechanisms 5, each set containing four L-shaped flip plates 9. The number of gravity-limiting support mechanisms 5 and L-shaped flip plates 9 can be increased or decreased according to requirements. The spacing between two adjacent L-shaped flip plates 9 can also be reduced or increased according to the workpiece condition, and the stacking spacing can be adjusted accordingly. At the same time, the flipping angle and length of the L-shaped flip plates 9, as well as the counterweight 15, also change accordingly.

[0024] Furthermore, the L-shaped tilting plate 9 is provided with tilting holes 14, a pad 13 is provided at one end of the L-shaped tilting plate 9, and a counterweight 15 is provided at the other end; a tilting shaft 12 is provided between the two columns 8, and the L-shaped tilting plate 9 rotates on the tilting shaft 12 through the tilting holes 14. The columns 8 are made of angle iron for supporting stability. The pad 13 is made of polyurethane block, which is glued to one end of the L-shaped tilting plate 9 for protecting the lowered workpiece; the counterweight 15 is welded to the other end of the L-shaped tilting plate 9 for counterweighting; (Reference) Figure 1-3 The diagram shows three states of the L-shaped flip plate 9: loaded, pre-loaded, and unloaded. When the robot gripper places the completed workpiece onto the L-shaped flip plate 9, the end with the pad 13 flips downward to the position of the first limit block 10, and the pad 13 is in a horizontal loading state. When the lower L-shaped flip plate 9 is in the loading state, the end with the counterweight 15 flips upward and pushes upward to the upper L-shaped flip plate 9, and the pad 13 is in a pre-loaded state. When the lifting device lifts the workpiece from the L-shaped flip plate 9, the end with the counterweight 15 flips downward to the position of the second limit block 11, and the pad 13 retracts between the two columns 8, presenting a non-loaded state. The workpiece handling is not affected by this interference.

[0025] Base 2 is a frame structure.

[0026] A base plate 6 is provided on the base 2, and a column 8 is provided on the base plate 6. In this embodiment, there are four base plates 6 in total. The four base plates 6 are welded to the base 2 according to the design position, and the column 8 is then welded to the base plates 6. The number of base plates 6 is adjusted according to the number of gravity-limiting support mechanisms 5.

[0027] Several limiting rods 7 are provided on one side of the base 2, and several insertion tubes 3 are also provided on the base 2, with insertion rods 4 inserted into the insertion tubes. In this embodiment, there are two limiting rods 7, and two insertion tubes 3 and two insertion rods 4. Before the workpieces are stacked, the transfer trolley is fixed at the lower workstation by the limiting rods 7, and the lower workstation cylinder is locked to ensure its unique position. The insertion rods 4 in the insertion tubes 3 are removed to prevent interference from the gripper during the robot stacking process. After the workpieces are stacked, the cylinder is unlocked, and the insertion rods 4 are inserted into the insertion tubes 3. The insertion rods 4 serve as handles, and the transfer trolley is manually moved to the upper workstation for hoisting. The limiting rods 7 are fixed at the upper workstation for hoisting, and the cylinder is locked to ensure its unique position. The hoisting device uses a front and rear gripping method, and the insertion rods 4 do not need to be removed during the hoisting process.

[0028] The base 2 is also equipped with casters 1 at its bottom. The four casters 1 are bolted to the bottom of the base 2 for easy movement.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
