[0039] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0040] The structure and functions of the utility model are as follows:

[0041] like Figure 1-Figure 6 As shown, an automatic liquid suction device includes a driving device 3, the output end of the driving device 3 is connected to a clamping assembly, the clamping assembly clamps a liquid suction gun 1, and the liquid suction gun 1 is connected to a first storage container through a connecting tube group; the driving device 3 drives the liquid suction gun 1 to move linearly in a vertical direction through the clamping assembly, so that the end of the liquid suction gun 1 is immersed in the solution of the second storage container, and then the solution in the second storage container is transferred to the first storage container through the liquid suction gun 1.

[0042] The clamping assembly includes a connecting plate fixed to the output end of the driving device 3 , and at least one first pneumatic clamping jaw 6 is fixed on the end surface of the connecting plate. The first pneumatic clamping jaw 6 is used to clamp the outer side wall of the liquid suction gun 1 .

[0043] An automatic liquid suction device of the utility model is installed at the working end of the manipulator, and reaches the top of the liquid suction port of the second storage container under the drive of the manipulator, so as to suck liquid; it includes a liquid suction gun 1, a driving device 3, and a first pneumatic clamp 6;

[0044] The driving device 3 is placed upright and can adopt a linear motor module or a cylinder and other devices, which can drive the connecting plate to move linearly in the vertical direction, thereby driving the first pneumatic clamp 6 to move linearly in the vertical direction through the connecting plate, and then driving the suction gun 1 to move linearly in the vertical direction.

[0045] like Figure 1 As shown, two first pneumatic clamps 6 are provided in the utility model, and the two first pneumatic clamps 6 are arranged along the axial direction of the liquid suction gun 1. The output end of a single first pneumatic clamp 6 adopts a V-shaped iron form, which can fit the outer wall shape of the barrel 101 and can accurately position the outer ring of the liquid suction gun 1, thereby ensuring the grasping accuracy;

[0046] The two first pneumatic clamps 6 are located at an upper gripping position on the barrel 101 of the suction gun 1, which can extend the stroke of the suction gun 1 and facilitate the muzzle 102 of the suction gun 1 to reach the bottom of the second storage container to reduce the amount of suction residue.

[0047] like Figure 3As shown, the structure of the liquid suction gun 1 is as follows: it includes a cylindrical barrel 101 with a hollow interior, one end of the barrel 101 is equipped with a funnel-shaped muzzle 102, and the other end is equipped with a joint 103, and the joint 103 is used to be installed with a connecting pipe assembly;

[0048] The gun barrel 101 is made of metal and is a hard tube;

[0049] The connector 103 is used to connect with the connecting pipe set. The connecting pipe set is a hose that is retracted and released by a hose reel. A check valve is installed on the connector 103 to prevent the solution from flowing back.

[0050] The muzzle 102 is a hose that can act as a buffer to prevent friction between the muzzle 102 and the inner bottom wall of the second storage container during liquid aspiration, thereby generating debris that affects the quality of the solution. It can also ensure that the liquid aspiration gun 1 absorbs as much solution as possible from the second storage container to reduce the residual amount.

[0051] A cleaning mechanism 2 is installed below the outer wall of the liquid suction gun 1 to remove the solution attached to the outer wall of the liquid suction gun 1;

[0052] like Figure 4-Figure 6 As shown, the cleaning mechanism 2 adopts a contact cleaning method, and the structure of the cleaning mechanism 2 is as follows: it includes a mounting plate 201, a mounting ring 202 fixed on the top of the mounting plate 201, mounting holes 203 are provided on the mounting ring 202 and the mounting plate 201 at the same time, and a plurality of annular mounting grooves 204 are provided on the inner wall surface of the mounting hole 203 corresponding to the mounting ring 202 at intervals, and a sealing ring 205 is installed in each mounting groove 204, and the sealing ring 205 is closely attached to the outer wall surface of the liquid suction gun 1, so as to remove the solution attached to the outer wall surface of the liquid suction gun 1;

[0053] Specifically, the gun barrel 101 passes through the mounting hole 203 and is tightly matched with the outer circumference of the gun barrel 101 through the sealing ring 205, so that the cleaning mechanism 2 is installed on the outer circumference of the gun barrel 101, and the cleaning mechanism 2 is arranged close to the muzzle 102 before the suction begins.

[0054] The cleaning mechanism 2 uses a non-contact cleaning method, such as ultrasonic water washing, to clean the solution attached to the outer wall surface of the gun barrel 101.

[0055] like Figure 1-Figure 2 As shown, a second pneumatic clamp 7 is fixed to the bottom of the driving device 3 , and the second pneumatic clamp 7 clamps the mounting plate 201 , thereby positioning the cleaning mechanism 2 and further improving the gripping stability of the suction gun 1 .

[0056] The driving device 3 is equipped with a driving cylinder 8 through a connecting seat 4, and the output end of the driving cylinder 8 is connected to a liquid collecting box 5, and the liquid collecting box 5 collects the residual liquid inside the liquid suction gun 1;

[0057] The top of the liquid collecting box 5 is provided with an opening, and when the driving cylinder 8 drives the liquid collecting box 5 to extend, the opening faces the gun muzzle 102, so that the liquid collecting box 5 can collect the solution remaining inside after the liquid suction gun 1 sucks the liquid;

[0058] When the driving cylinder 8 drives the liquid collecting box 5 to retract, the liquid collecting box 5 is prevented from interfering with the action of the liquid suction gun 1 .

[0059] The working process of the utility model is as follows:

[0060] The automatic liquid suction device is installed at the working end of the manipulator;

[0061] Select a suitable suction gun 1, start the first pneumatic gripper 6 to grab the outer circumference of the gun barrel 101, and at the same time, start the second pneumatic gripper 7 to grab the mounting plate 201;

[0062] After the grasping is completed, the first pneumatic clamp 6 and the second pneumatic clamp 7 are locked, so as to grasp the liquid suction gun 1 and the cleaning mechanism 2 installed thereon, and ensure the grasping stability of the liquid suction gun 1;

[0063] Driven by the manipulator, the automatic liquid suction device reaches the top of the liquid suction port of the second storage container, and then the driving device 3 is started, driving the first pneumatic clamp 6 to perform a linear downward motion in the vertical direction, thereby driving the liquid suction gun 1 to descend in the vertical direction and extend into the interior of the second storage container through the liquid suction port of the second storage container, so that the gun muzzle 102 is immersed in the solution in the second storage container;

[0064] A delivery pump is installed on the delivery pipe assembly, and the delivery pump provides drive, so that the solution in the second storage container flows into the first storage container through the muzzle 102, the barrel 101, the joint 103, and the delivery pipe assembly in sequence;

[0065] During the liquid aspiration process, as the liquid level in the second storage container drops, the driving device 3 drives the liquid aspiration gun 1 to drop synchronously, so that the liquid aspiration gun 1 is always in a liquid aspiration state;

[0066] After the liquid aspiration is completed, the driving device 3 drives the liquid aspiration gun 1 to rise until it returns to its original position;

[0067] During the upward movement of the suction gun 1, since the cleaning mechanism 2 is not driven by the driving device 3, at this time, the sealing ring 205 scrapes off the solution attached to the outer wall of the barrel 101 through the inclined surface 206; after the suction gun 1 returns to its original position, the driving cylinder 8 drives the liquid collecting box 5 to extend, thereby preventing subsequent solution from dripping into the production environment.

[0068] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
