Description

Technical Field

[0001] The invention relates to the technical field of test equipment, and in particular to a mechanical arm vacuum operation box. Background Art

[0002] Vacuum glove boxes can provide an ultra-pure environment without water, oxygen and dust. They are widely used in laboratories and in the production of lithium-ion batteries and semiconductors. Currently, gloves are installed on vacuum glove boxes on the market. Operators wear gloves to operate materials and equipment in the glove box. However, the range of operation that human arms can perform is limited, and the operation precision of human hands with gloves is not enough, the operation is inconvenient, and the labor intensity, efficiency and safety risks of manual operation are high. At the same time, since rubber gloves have great elasticity and various complex experimental operations with ductility need to be performed after human hands wear gloves, various experimental operations cannot be performed in a vacuum state. It is necessary to evacuate both the inside and outside of the gloves at the same time, thereby evacuating the gloves without a pressure difference inside and outside the gloves, and then introducing inert gas to make the inside of the box (the inside of the glove) and the outside of the box (that is, the inside of the glove) and the outside of the box (that is, the inside of the glove) separate. There is no pressure difference in the air environment (outside the gloves), and then the vacuum chamber door of the glove port is opened, and the person puts on the gloves to operate. Therefore, a vacuum operation box with a robotic arm has now appeared. The material can be operated by the robotic arm by setting a program without manual operation. The designed glove-free fully automatic vacuum robotic arm operation box can meet the needs of industrial fully automatic production and fully automatic experimental operation; but because the air in the vacuum glove box needs to be evacuated and then filled with high-purity inert gas when it is used, the existing glove box cannot quickly remove oxygen, water, and other organic gases in the air during evacuation. This treatment method, on the one hand, is bound to lead to a long treatment time. On the other hand, if these gases are not effectively treated, they will have a great impact on the experiment. Therefore, it is necessary to design a more efficient and more thorough treatment operation box. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a robot arm vacuum operation box, which drives out the air inside the box through a reciprocating wind surface, and purifies the air inside the box quickly and thoroughly.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] The present invention provides a robot arm vacuum operation box, comprising a box body, a bracket inside the box body which reciprocates on a horizontal plane, and a driving mechanism for driving the box body to move. A vent a is provided on one side of the box body, and a vent b is provided on the other side. The bracket is provided with a plurality of nozzles with nozzles pointing to the center of the box body, and the nozzles are connected to an external air source through pipelines. When the driving mechanism drives the bracket to move forward, the nozzles are set to form an acute angle between their spraying direction and the extension direction of the movement through a swing mechanism.

[0006] Furthermore, the swing mechanism comprises a mounting plate fixedly connected to the side of the nozzle away from the nozzle opening, an elastic body tightly attached to the inner wall of the box is fixedly arranged on the mounting plate, and the nozzle is hinged in the bracket via a rotating shaft.

[0007] Furthermore, the bracket is provided with an air inlet, and an air flow channel communicating with the air inlet is provided inside, and the rotating shaft is provided with a through hole communicating with the air flow channel and the nozzle.

[0008] Furthermore, the mounting plate is provided with a C-shaped groove for clamping the elastic body.

[0009] Furthermore, the cross section of the nozzle is rectangular.

[0010] Furthermore, the bracket is formed by the cooperation and installation of symmetrical shells.

[0011] Furthermore, the driving mechanism includes a motor outside the box, a screw rod inside the box that is transmission-connected to the motor output end, and a guide rod arranged parallel to the screw rod. The bracket is provided with a screw nut that cooperates with the screw rod, and a rod sleeve that cooperates with the guide rod.

[0012] Furthermore, a vent c is provided in the box body, and the vent c is connected to the air inlet through a hose.

[0013] Furthermore, the box body is made of stainless steel, an observation window is provided on the box body, and a lighting system is arranged inside the box body.

[0014] Compared with the prior art, the beneficial effect of the present invention is that the operating box drives out the air inside the box through the reciprocating wind surface, and purifies the air inside the box quickly and thoroughly.

[0015] 1. In the present invention, when the driving mechanism drives the bracket to move, the friction between the elastic body and the inner wall of the box causes the rear end of the nozzle to lag behind, and the front end forms an acute angle with the extension direction of the movement, which ensures the formation of the blocking surface and can wipe off the dirt on the inner wall of the box, killing two birds with one stone.

[0016] 2. The elastic body of the present invention is easy to install and, when the elastic body is rubbed, it is also easy to replace. It only needs to be clamped in the C-shaped slot.

[0017] 3. The present invention uses a robotic arm to replace traditional gloves, and no manual operation is required to meet the needs of industrial fully automatic production and fully automatic experimental operations under extreme conditions; and the robotic arm uses a robotic arm with more than 3 controllable joints, which controls various operation requirements through programs to meet different production and experimental operation requirements.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7In a specific embodiment, a robotic arm vacuum operation box provided by an embodiment of the present invention includes a box body 1, a bracket 2 reciprocating on a horizontal plane inside the box body 1, and a driving mechanism driving the box body 1 to move. A vent a is provided on one side of the box body 1, and a vent b is provided on the other side; a plurality of nozzles 3 with nozzles pointing to the center of the box body 1 are provided on the bracket 2, and the nozzles 3 are connected to an external air source through a pipeline. When the driving mechanism drives the bracket 2 to move forward, the nozzles 3 are set to form an acute angle with the extension direction of the movement through a swing mechanism.

[0029] Specifically, an operation room is provided in the box 1, a workbench is provided in the operation room, at least two robotic arms are installed in the operation room, and more than three joints are controllable robotic arms. Various operation requirements are controlled by programs to meet different production and experimental operation requirements. The specific installation device is installed according to user needs; a sealed box door is provided on one side of the operation room, and a pressure gauge and a vacuum air valve connected to the operation room are provided above the box 1.

A bracket 2 that reciprocates on a horizontal plane is provided in the box 1 along its length extension direction, and a plurality of nozzles 3 with nozzles pointing to the center of the box 1 are installed on the bracket 2. When the driving mechanism drives the bracket 2 to move forward, the swing mechanism drives the nozzles of each nozzle 3 to face forward.

[0031] When in use, after placing the test object on the manipulator, close the sealed box door. Figure 1As shown, when the bracket 2 is moved to the left, the air flow switching system works as a in and b out, the vent a takes in inert gas, and the vent b recovers and discharges waste gas. The driving mechanism drives the bracket 2 to move to the left, and the swing mechanism makes the nozzle 3 spray direction form an acute angle with the extension direction of the movement. At this time, when each nozzle sprays inert gas forward, a blocking surface is formed, which drives the miscellaneous gas and active gas to move to the left and be discharged from the vent b; when it moves to the leftmost end, the driving mechanism drives the bracket 2 to move to the right again. At this time, the air flow switching system works as b in and a out , inert gas enters through vent b, exhaust gas is recovered and discharged through vent a, and the swing mechanism makes the spray direction of nozzle 3 form an acute angle with the extension direction of movement. When each nozzle sprays inert gas forward, a blocking surface is formed to drive the miscellaneous gas and active gas to move to the right, and the miscellaneous gas and active gas to move to the right and be discharged from vent a. This cycle is repeated several times in sequence, so that the active substances in the air in the operating box are quickly and thoroughly treated, and then related tests or vacuum tests are carried out, which improves efficiency and saves the amount of inert gas.
