The frame 10 may serve as an integral fixture and mounting of the adsorption apparatus 1. The first adsorption component 20 and the second adsorption component 30 can perform an adsorption function, so that the adsorption stability of the adsorption device 1 can be improved, wherein the first adsorption component 20 comprises: the adsorption modules are connected in series and in parallel, so that the adsorption of the first adsorption module 20 can be improved. The locking assembly 40 can provide a locking function to prevent the locked object from being displaced. The control valve 50 is used for controlling the relative movement distance of the objects.

As shown in fig. 1, 4-7, the first adsorption module 20 is fixed on the frame 10, so that the stability of the first adsorption module 20 can be ensured, and the first adsorption module 20 can be more stable when adsorbing boards such as circuit boards. The first adsorption module 20 includes: the first adsorption parts 21 are distributed at intervals, the first adsorption parts 21 are main bodies of the first adsorption components 20 and have adsorption effects, and the main bodies act on plates such as a circuit board, in addition, the first adsorption parts 21 are distributed at intervals, so that the adsorption effect of the first adsorption components 20 can be improved, the stress among the first adsorption parts 21 is uniform, and the phenomenon that one first adsorption part 21 is damaged due to overlarge stress is avoided.

As shown in fig. 1, 8 and 9, the second adsorption component 30 is disposed on the frame 10, so that the stability of the second adsorption component 30 can be ensured, and the second adsorption component 30 can be more stable when adsorbing boards such as circuit boards. And the second adsorption component 30 moves in a direction close to or far from the first adsorption component 20, that is, the second adsorption component 30 can move in a direction close to or far from the first adsorption component 20, so that the distance between the second adsorption component 30 and the first adsorption component 20 can be adjusted, and thus, the distance between the second adsorption component 30 and the first adsorption component 20 can be adjusted according to the distance between two ends of a board such as a circuit board, so that the adsorption device 1 is suitable for boards such as circuit boards with different sizes, and the adsorption device 1 can better adsorb the boards such as the circuit boards. The second adsorption assembly 30 includes: the second of a plurality of interval distribution adsorbs piece 31, can promote the adsorption efficiency of second adsorption component 30 like this, can make a plurality of seconds adsorb the atress between the piece 31 even moreover, avoids a certain second to adsorb 31 atress too big and appear damaging.

That is, when the first locking member 42 and the second locking member 43 are locked, the elastic holding member 41 provides an elastic force of the first locking member 42 toward the second locking member 43, so that the first locking member 42 contacts with the second locking member 43 and maintains a locked state, the first locking member 42 is disposed on the second suction module 30, the second locking member 43 is disposed on the frame 10, so that the second suction module 30 is locked with the frame 10, and the second suction module 30 cannot move in a direction approaching to or departing from the first suction module 20. When a pulling force opposite to the direction of the elastic force is provided to the first locking member 42, and the pulling force is greater than the elastic force, the locking relationship between the first locking member 42 and the second locking member 43 can be released, so that the second suction assembly 30 can move in a direction close to or away from the first suction assembly 20, thereby adjusting the distance between the second suction assembly 30 and the first suction assembly 20, and the suction device 1 can be applied to boards such as circuit boards with different sizes, and when the distance between the second suction assembly 30 and the first suction assembly 20 is adjusted, the pulling force on the first locking member 42 is released. The elastic force helps the first locking member 42 to return to the original position, and the first locking member 42 and the second locking member 43 return to the locked position again, so that the second suction assembly 30 is prevented from shifting and the set distance between the second suction assembly 30 and the first suction assembly 20 is prevented from being disturbed.

As shown in fig. 1, a control valve 50 is provided at the first adsorption module 20 and/or the second adsorption module 30 to control opening and closing of the first adsorption member 21 and/or the second adsorption member 31. That is, by operating the control valve 50, the first adsorption element 20 and/or the second adsorption element 30 can be opened or closed, so that the distance between the first adsorption element 21 and/or the second adsorption element 31 can be adjusted, and in addition, the direction in which the first adsorption element 20 and/or the second adsorption element 30 is opened or closed is in the same plane as the direction in which the second adsorption element 30 approaches or departs from the first adsorption element 20, and the moving direction is different, so that the distance between the first adsorption element 21 and/or the second adsorption element 31 can be adjusted according to the distance between the other two ends of the board, etc., so that the adsorption device 1 is suitable for boards, etc., with different sizes, and the adsorption device 1 can better adsorb the board, etc.

When an operator operates the operating member 47, the operating arm 470 can be pressed by hand, and the operating arm 470 and the connecting arm 471 are bent, so that the operating arm 470 can generate a pulling force on the connecting arm 471, and the connecting arm 471 is connected with the first transmission member 45, so that the connecting arm 471 pulls the first transmission member 45 in a direction opposite to the elastic force, and the locking state between the first locking member 42 and the second locking member 43 is released. In addition, the operating arm 470 protrudes from the second mounting seat 46, so that the operator can press the operating arm 470 conveniently, and the whole operation process is simpler and more convenient.

The control valve 50 is set as a mechanical switch valve, and the mechanical switch valve is provided with a switch member 53 and an indication sign 51, so that an operator can select the mechanical switch valve to be opened according to the indication sign 51, and then open the switch member 53 by hand, which is more convenient to operate, so that the first adsorption assembly 20 and/or the second adsorption assembly 30 are opened or closed by a corresponding distance, and the length of the adsorption device 1 in the second direction is adjusted. In addition, the control valve 50 further includes: a mounting plate 52, a three-way joint 54 and a right-angle two-way joint 55, so that the control valve 50 can be fixedly arranged on the first adsorption assembly 20 and/or the second adsorption assembly 30, and the communication of the control valve 50 can be ensured.

In addition, as shown in fig. 1, the adsorption apparatus 1 further includes: the scale 60 and the indicator 70, the scale 60 is disposed on the frame 10, the indicator 70 is disposed on the second adsorption component 30, and the indicator 70 is matched with the scale 60. The scale 60 is disposed on the frame 10, and the scale 60 is disposed on the longer one of the at least two third connecting rods 13, so that when the second adsorption component 30 moves in a direction approaching or moving away from the first adsorption component 20, a moving distance of the second adsorption component 30 approaching or moving away from the first adsorption component 20 can be measured according to the scale 60, and thus the size of the adsorption device 1 in the second direction is adapted to the size of a board, such as a circuit board. In addition, the indicating member 70 is disposed on the second adsorption assembly 30, and the indicating member 70 is matched with the scale 60, that is, when the second adsorption assembly 30 moves in a direction approaching or moving away from the first adsorption assembly 20, the indicating member 70 moves simultaneously with the second adsorption assembly 30, so that the indicating member 70 indicates different positions on the scale 60, which can make the indicating result more intuitive, and can more conveniently and accurately measure the distance that the second adsorption assembly 30 approaches or moves away from the first adsorption assembly 20.
