[0002] In the prior art, many processing procedures are completed through the interaction between the liquid and the workpiece. Taking the electroplating of metal workpieces as an example, the liquid receiving device used in the electroplating is generally used when the workpiece enters the next process after the electroplating is completed. Its purpose is to prevent the electroplating liquid on the workpiece from falling onto the ground or other mechanisms to prevent pollution. The traditional liquid receiving device requires a separate power mechanism to drive the liquid receiving box and other mechanisms to reach the receiving position when receiving the liquid. Since the power device of the liquid receiving device and the power device for lifting the workpiece are independent mechanisms, a waiting time for mutual coordination needs to be set aside between the workpiece rising and the liquid contacting action, resulting in a more complicated control process of the electroplating system, which increases the cycle time and reduces the electroplating efficiency.

[0027] When the lifting arm 2 and the workpiece 100 are lowered, the liquid receiving box 3 swings outward to the outside of the workpiece 100 under the action of gravity or external thrust, and the limit locking mechanism locks the liquid receiving box 3 in the position after the outward swing;

[0028] When the lifting arm 2 rises to a preset height, it abuts against the blocking portion 40, and the lifting force applied to the blocking portion 40 drives the vertical slide bar 4 to rise. The vertical slide bar 4 drives the first swing arm 30 and the second swing arm 31 to swing toward the workpiece 100 through the linkage arm 32, thereby driving the liquid receiving box 3 to swing to the bottom of the workpiece 100.

[0029] In the above device, during the rising or falling process of the lifting arm 2, the processing step and the liquid receiving step can be performed accordingly. When performing the processing step, the lifting arm 2 drives the workpiece 100 to descend, and the liquid receiving box 3 swings outward to the outside of the workpiece 100 under the action of gravity or external thrust, and the liquid receiving box 3 is locked in the position after the outward swing by the limit locking mechanism; when performing the liquid receiving step, the lifting arm 2 rises to a preset height and then abuts against the blocking portion 40, and the lifting arm 2 applies a lifting force to the blocking portion 40, and drives the vertical slide bar 4 to rise, and then drives the first swing arm 30 and the second swing arm 31 to swing toward the workpiece 100 through the linkage arm 32, until the liquid receiving box 3 swings to the bottom of the workpiece 100, and the liquid dripping on the workpiece 100 is received by the liquid receiving box 3. Compared with the prior art, the present invention synchronously drives the liquid receiving box 3 to enter the liquid receiving position during the rising process of the workpiece 100. During the descending process of the workpiece 100, the liquid receiving box 3 swings outward by its own gravity or thrust from the outside to perform the opening action, and is locked in the open position after opening. Based on the above structure, the linkage performance of the present invention is better, there is no need to set a waiting time, the system control process can be effectively simplified, and the production efficiency can be improved. In addition, the present invention does not need to set an independent power mechanism for the liquid receiving box 3, which greatly saves equipment costs and better meets production needs.

[0030] In order to better cooperate with the lifting arm 2 , in this embodiment, the blocking portion 40 is located at the top end of the vertical sliding rod 4 , and the blocking portion 40 is bent toward the upper side of the lifting arm 2 .

[0031] In this embodiment, after the liquid receiving box 3 is swung outward, the limit locking mechanism is used to lock the liquid receiving box 3. In order to realize the locking function, in this embodiment, see Figures 4 to 9 The limit locking mechanism 5 includes a rocking arm 50 located below the resisting portion 40, a first end of the rocking arm 50 is located above the lifting arm 2, a second end of the rocking arm 50 is located outside the lifting arm 2, and the second end of the rocking arm 50 is hinged to the frame 1, and the second end of the rocking arm 50 is formed with a driving portion 51 bent upward, and an arc-shaped locking groove 41 is provided at the connection between the resisting portion 40 and the vertical slide bar 4, the upper end of the locking groove 41 extends along the length direction of the resisting portion 40, and the lower end of the locking groove 41 extends along the length direction of the vertical slide bar 4, and a locking pin 52 is provided on the driving portion 51, and the locking pin 52 is inserted in the locking groove 41 and the two are slidably connected, and the limit locking mechanism 5 also includes an elastic mechanism 53 for driving the first end of the rocking arm 50 to swing downward, wherein:

[0032] When the lifting arm 2 and the workpiece 100 descend and the liquid receiving box 3 swings outward, the vertical slide bar 4 slides downward, the elastic mechanism 53 drives the rocker 50 to swing downward, and the locking pin 52 slides along the locking groove 41 to the side of the blocking portion 40, and the locking pin 52 locks the vertical slide bar 4 in a preset vertical position;

At this time, the vertical slide bar 4 is in a liftable state. When the lifting arm 2 continues to rise, it drives the vertical slide bar 4 to rise accordingly, and then drives the liquid receiving box 3 to swing downward to the bottom of the workpiece 100.

[0035] In order to facilitate the application of elastic force, in this embodiment, the elastic mechanism 53 includes a torsion spring, and the two ends of the torsion spring are respectively in contact with the frame 1 and the rocker 50, and the elastic force applied by the torsion spring drives the first end of the rocker 50 to swing downward.
