Referring to fig. 1, fig. 1 shows an exploded view of a suction apparatus, a workpiece, and a box according to an embodiment of the present utility model, and a suction apparatus 10 according to an embodiment of the present utility model is provided for picking up a workpiece 20 to separate the workpiece 20 from the box 30. The workpiece 20 may be, for example, a display module, and the display module may include a plurality of display modules spliced in an array. The adsorption apparatus 10 can pick up any one of the display modules to be separated from other display modules and the case 30 for maintenance thereof.

Referring to fig. 2 to 4, in one embodiment, the suction apparatus 10 includes a suction cup 100, a negative pressure device 200, a pressure detector 300, and a control circuit board 400. The suction cup 100 is used for being matched with the workpiece 20 to form a closed matching cavity 101, and an air flow hole 110 communicated with the matching cavity 101 is formed in the suction cup 100. A negative pressure device 200 communicates with the airflow hole 110 to form a negative pressure in the fitting chamber 101. The pressure detector 300 is provided in the fitting chamber 101 or communicates with the fitting chamber 101 to detect a pressure value. The pressure detector 300 is electrically connected with the control circuit board 400, and the control circuit board 400 is electrically connected with the negative pressure device 200 to negative the pumping degree of the negative pressure device 200 according to the pressure value.

In the above-described suction apparatus 10, the suction cup 100 is engaged with the workpiece 20 to enclose the relatively closed engagement chamber 101, and the negative pressure generator 200 is capable of forming a negative pressure in the engagement chamber 101 through the airflow hole 110. Thus, the workpiece 20 and the chuck 100 can be pressed toward each other by the atmospheric pressure, so that the workpiece 20 can be fixed relative to the chuck 100. In this way, the suction apparatus 10 forms a force application point on the end surface of the workpiece 20 by the cooperation of the suction cup 100 and the negative pressure device 200, so that the suction apparatus 10 can conveniently control the spatial position of the sucked workpiece 20.

Further, the pressure detector 300 can detect the pressure value in the matching chamber 101, and the control circuit board 400 is electrically connected with the negative pressure device 200 to control the suction degree of the matching chamber 101. That is, by matching the negative pressure device 200 with the control circuit board 400, the pressure value of the negative pressure device 200 in the matching cavity 101 can be controlled, so that the negative pressure formed in the matching cavity 101 is in an ideal negative pressure range, and the workpiece 20 is prevented from being deformed or damaged under the action of the atmospheric pressure due to the excessively large difference between the negative pressure value in the matching cavity 101 and the atmospheric pressure.

It is understood that the negative pressure mentioned above refers to a lower pressure relative to the atmospheric pressure. The way in which the control circuit board 400 controls the suction degree of the negative pressure device 200 may be to control the output power of the negative pressure device 200 and/or control the rotation speed of an actuator in the negative pressure device 200.

Referring to fig. 3, in one embodiment, the adsorption apparatus 10 further includes a battery 500, and the battery 500 is electrically connected to the control circuit board 400 to supply power to the control circuit board 400 and to supply power to the negative pressure device 200 through the control circuit board 400. It can be understood that the control circuit board 400 controls the suction degree of the negative pressure device 200, so that the workpiece 20 is prevented from being deformed due to excessive force; and simultaneously, the energy consumption of the battery 500 can be reduced, and the cruising ability of the adsorption equipment 10 can be improved.

Referring to fig. 3, in one embodiment, the suction apparatus 10 further includes a housing 600, and the housing 600 is fixedly connected to the suction cup 100. The negative pressure device 200, the battery 500 and the control circuit board 400 are all disposed in the housing 600. The holding part 620 is formed at one side of the housing 600 away from the suction cup 100, and the overall position of the suction apparatus 10 can be more conveniently controlled by the holding part 620, so that the workpiece 20 can be more conveniently separated from the case 30.

Referring to fig. 2 to 4, in one embodiment, the housing 600 is provided with an air outlet 610, and the suction cup 100 is provided with a suction hole 140 communicating with the mating cavity 101. The air inlet hole 210 of the negative pressure device 200 faces the suction hole 140, and the air outlet hole (not shown, the same applies hereinafter) of the negative pressure device 200 communicates with the air outlet 610. In this way, the negative pressure device 200 can suck the gas in the fitting chamber 101 through the gas flow hole 110 and discharge the sucked gas to the outside of the case 600 through the gas discharge port 610.

Referring to fig. 4, in one embodiment, the adsorption apparatus 10 further includes a sealing ring 700, and a support plate 800. The support plate 800 is connected to the suction cup 100. The pressure detector 300 is located at a side of the support plate 800 away from the suction cup 100, and the pressure detector 300 communicates with the mating cavity 101 through the support plate 800 and the suction cup 100. The sealing ring 700 is provided between the pressure detector 300 and the support plate 800 and around the pressure detector 300, thereby enabling the space inside the fitting chamber 101 to be sealed. It will be appreciated that since the pressure detector 300 is required to detect the pressure value in the mating chamber 101 and to transmit the detection result to the control circuit board 400, the pressure detector 300 is typically required to be installed through the suction cup 100. Since the suction cup 100 is usually an elastic member and/or a flexible member, the suction cup 100 is easy to deform when being subjected to an external force, and the tightness of the two opposite sides of the suction cup 100 is not easily ensured if the pressure detector 300 is directly arranged through the suction cup 100. In this embodiment, by connecting the support plate 800 to the suction cup 100, and disposing the seal ring 700 between the support plate 800 and the pressure detector 300 and surrounding the pressure detector 300 with the seal ring 700, it is possible to ensure that no leakage occurs between the pressure detector 300 and the suction cup 100 in a comprehensive and stable manner.

With continued reference to fig. 4, in one embodiment, the housing 600 is provided with an abutment post 640, and the abutment post 640 abuts against a side of the pressure detector 300 away from the support plate 800. In this way, the pressure sensor and the support plate 800 can be kept relatively fixed by the abutting action of the abutting post 640; and simultaneously, the sealing ring 700 can be clamped, so that the tightness of the matching cavity 101 is further ensured.

With continued reference to fig. 4, in one embodiment, the suction cup 100 is provided with an extension 120 connected to the sealing ring 700, that is, the suction cup 100 is integrally connected to the sealing ring 700 through the extension 120, so as to form a unitary structure. In other words, the suction cup 100 is designed integrally with the seal ring 700. It will be appreciated that the negative pressure device 200 will vibrate to some extent during operation, and that the seal 700 will be in direct contact with the vibrating negative pressure device 200 and will be likely to undergo a play displacement, resulting in leakage. In this embodiment, by integrally setting the sealing ring 700 and the suction cup 100, relative displacement and movement between the sealing ring 700 and the suction cup 100 can be avoided, and leakage can be avoided.

Moreover, the abutting post 640 abuts against the pressure detector 300 and is combined with the supporting plate 800 to clamp the sealing ring 700, and the sealing ring 700 and the sucking disc 100 are matched to be integrally designed, so that the tightness between the pressure detector 300 and the sucking disc 100 can be ensured, and the negative pressure in the matching cavity 101 is prevented from leaking.

The support plate 800 is provided with a first detection hole 810, the extension part 120 is hollow to form a second detection hole 121, and the second detection hole 121 is communicated with the matching cavity 101. The walls of the first detection hole 810 and the second detection hole 121 are sleeved outside the pressure detector 300 from outside to inside. In this way, the pressure detector 300 can penetrate the first and second detection holes 810 and 121 to communicate with the fitting chamber 101.

Further, the radial dimension of the part of the structure of the pressure detector 300 located on the side of the support plate 800 away from the suction cup 100 is larger than the radial dimension of the first detection hole 810, that is, the contact between the pressure detector 300 and the side of the wall of the first detection hole 810 enables at least part of the structure of the pressure detector 300 to be located outside the first detection hole 810, so that the pressure detector 300 can be prevented from being pushed into the matching cavity 101 by the atmospheric pressure.

With continued reference to fig. 4, in one embodiment, a side of the support plate 800 adjacent to the negative pressure device 200 protrudes to form a fence 820, and the fence 820 is disposed around the seal ring 700. The enclosing barrier 820 is enclosed on the periphery of the sealing ring 700, so that the position of the sealing ring 700 can be limited on one hand; on the other hand, the seal ring 700 can be co-extruded with the pressure detector 300, so that the seal ring 700 is deformed and fills up the gap between the pressure detector 300 and the support plate 800, and the tightness between the pressure detector 300 and the support plate 800 is ensured.

Referring to fig. 3 in combination with fig. 5, in one embodiment, the adsorption apparatus 10 further includes a conductive member 900, where the conductive member 900 is movably disposed inside and outside the housing 600. The control circuit board 400 is provided with a button 410 capable of controlling the start and stop of the negative pressure device 200 when triggered. The conductive element 900 can contact and trigger the button 410 or be separated from the button 410 when moving. In this manner, by driving the movement of the conductive member 900 relative to the housing 600, the button 410 can be activated outside the housing 600 to cause the suction apparatus 10 to start sucking the workpiece 20 or cause the suction apparatus 10 to lower the workpiece 20.

Referring to fig. 5, in one embodiment, the holding portion 620 is provided with a limiting groove 621 along the moving direction of the conductive member 900, and the housing 600 is provided with a through hole 630 communicating with the limiting groove 621, and the through hole 630 faces the button 410. The conductive element 900 is slidably matched with the groove wall of the limiting groove 621 and the hole wall of the through hole 630, so that the groove wall of the limiting groove 621 and the hole wall of the through hole 630 can limit and guide the displacement of the conductive element 900, and the conductive element 900 can be ensured to stably trigger the button 410.

With continued reference to fig. 5, in one embodiment, the holding portion 620 is provided with a pressing hole 622 penetrating through the holding portion 620, and the pressing hole 622 is in communication with the limiting slot 621. A portion of the structure of the conductive member 900 extends from the limiting groove 621 into the pressing hole 622 and at least partially protrudes out of the pressing hole 622. Thus, the trigger button 410 can be easily made to be held by the grip 620, and the suction apparatus 10 can be easily operated with one hand.

Referring to fig. 6, in one embodiment, the adsorption apparatus 10 may further include a propping member 130. The propping piece 130 is located in the matching cavity 101, one end of the propping piece 130 is connected with the sucker 100, and the other end of the propping piece 130 is used for propping against the workpiece 20. In this way, the abutting piece 130 can abut against the workpiece 20, so that deformation of the upper part of the workpiece 20 under the action of atmospheric pressure is avoided.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
