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.

In this way, the transmission between the first transmission member 45 and the first locking member 42 can be made more convenient and stable.
In addition, as shown in fig. 3, an annular protrusion 450 is disposed on the outer periphery of the first transmission member 45, the elastic retaining member 41 is sleeved on the first transmission member 45, and two ends of the elastic retaining member 41 are respectively engaged with the first mounting seat 44 and the annular protrusion 450. That is, the annular protrusion 450 is disposed on the outer periphery of the first transmission member 45, so that both ends of the elastic retaining member 41 can be respectively engaged with the first mounting seat 44 and the annular protrusion 450 while the elastic retaining member 41 is sleeved on the first transmission member 45, when a pulling force in a direction opposite to the elastic force is provided to the first transmission member 45, the first transmission member 45 can extrude the elastic retaining member 41 through the annular protrusion 450, so as to generate an elastic force, and after the pulling force is removed, the elastic retaining member 41 can provide the elastic force of the first transmission member 45 through the annular protrusion 450, so that the first transmission member 45 drives the first locking member 42 to move, and the first locking member 42 is in locking engagement with the second locking member 43. Therefore, the transmission between the first transmission piece 45 and the first locking piece 42 can be more reasonable, and the matching between the first transmission piece 45 and the first locking piece 42 is more stable.

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.
