Description

Technical Field

[0001] The present invention relates to the technical field of material adsorption, and in particular to an adsorption device and its control system. Background Art

[0002] The material adsorption mechanisms in the prior art are generally divided into three types. The first is the permanent magnet adsorption mechanism, which mainly relies on the force generated by the permanent magnet on the ferromagnetic object to be adsorbed, and the objects to be adsorbed are relatively limited. The second is the electromagnetic adsorption mechanism, which needs to be continuously powered to maintain the adsorption force, and the products adsorbed by it are also ferromagnetic objects. Using this adsorption mechanism not only has relatively limited objects to be adsorbed, but also has the problem of high energy consumption during long-term power supply. The third is the vacuum adsorption mechanism, which relies on the gas source system and has high requirements for the surface flatness of the object to be adsorbed, and cannot adsorb porous or rough objects to be adsorbed.

[0003] However, during industrial use, the objects to be adsorbed are diverse, including ferromagnetic objects to be adsorbed and non-ferromagnetic objects to be adsorbed, smooth-surface objects to be adsorbed and rough-surface objects to be adsorbed. In the existing use process, generally, the adsorption mechanism is selected directionally according to the material and surface smoothness to complete the adsorption of the object to be adsorbed. Using this method, although the adsorption of the object to be adsorbed can be effectively achieved, it is necessary to replace the adsorption mechanism directionally according to the different objects to be adsorbed, and the operation is cumbersome. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the present invention provides an adsorption device and its control system. To achieve the above purpose, the present invention adopts the following technical solutions: An adsorption device includes an upper cover body and a lower cover body that are buckled together to jointly form an installation cavity. A permanent magnet adsorption mechanism that allows a force to be applied to a ferromagnetic object to be adsorbed is arranged in the installation cavity, and an electromagnetic adsorption mechanism that is selectively activated to apply a force to the ferromagnetic object to be adsorbed. Wherein, an elastic part is further arranged on the lower cover body, and the elastic part and the lower cover body jointly form a vacuum cavity. A negative pressure component is also arranged in the installation cavity, and the negative pressure component is configured to be selectively activated to pump air into the vacuum cavity, so that the vacuum cavity adsorbs the object to be adsorbed.

[0005] Furthermore, two permanent magnet adsorption mechanisms and two electromagnetic adsorption mechanisms are respectively arranged and distributed in the installation cavity in a corresponding manner, so that when the force is generated, the force presents a rectangle.

[0006] Further, an installation groove penetrating the lower cover body is provided on the lower cover body, and the permanent magnet adsorption mechanism is arranged corresponding to the installation groove.

[0007] Further, the permanent magnet adsorption mechanism is composed of a plurality of strip-shaped permanent magnets and arranged in a Halbach array to increase the magnetic force on the adsorption side of the permanent magnet adsorption mechanism.

[0008] Further, the electromagnetic adsorption mechanism includes an electromagnet arranged in the cavity and a power supply component connected to the electromagnet through a wire for supplying power to the electromagnet, so that the electromagnet generates an acting force on the ferromagnetic object to be used.

[0009] Further, an installation opening penetrating the lower cover body is also provided on the lower cover body, and the installation opening is arranged corresponding to the electromagnet.

[0010] Further, the negative pressure component includes a negative pressure pump for pumping air from the vacuum chamber and a one-way valve arranged at the air extraction end of the negative pressure pump. When the negative pressure pump is working for air extraction, the one-way valve allows the negative pressure pump to communicate with the vacuum chamber. The one-way valve is configured so that the pressure in the vacuum chamber can be continuously maintained by the one-way valve after the negative pressure pump completes the air extraction work on the vacuum chamber.

[0011] According to the second aspect of the present invention, an adsorption device control system is provided. The control system includes a control board, a power supply component, a proximity sensor, and a buzzer connected together in sequence. The control board is configured to allow the power supply component to supply power to the proximity sensor in a selectable manner. The proximity sensor is configured to allow the object to be used to be identified, and when the object to be used cannot fully cover the proximity sensor, the buzzer is allowed to be turned on.

[0012] Further, the control system also includes a Hall sensor and an electromagnet connected together in sequence. The Hall sensor is configured to be connected to the power supply component, and after the ferromagnetic object to be used is identified, the Hall sensor allows the electromagnet to be turned on to adsorb the ferromagnetic object to be used.

[0013] Further, the control system also includes a negative pressure pump for pumping air from the vacuum chamber connected to the power supply component and a vacuum pressure sensor connected to the control board for monitoring the vacuum pressure in the vacuum chamber. The vacuum pressure sensor is configured to, according to its threshold value, selectively enable the control board to turn on or off the operation of the power supply component to supply power to the negative pressure pump.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, an upper cover body and a lower cover body that are buckled together to jointly form an installation cavity are provided. Inside the installation cavity, a permanent magnet adsorption mechanism that allows a magnetic force to be applied to a magnetic usage object and an electromagnetic adsorption mechanism that can be selectively activated to apply a magnetic force to the magnetic usage object are provided. At the same time, a negative pressure assembly is also provided inside the installation cavity. The negative pressure assembly is configured to be selectively activated to pump air into a vacuum cavity, so that the vacuum cavity can adsorb the usage object. In this way, when the device adsorbs a magnetic usage object, the permanent magnet adsorption mechanism, the electromagnetic adsorption mechanism, and the negative pressure assembly can jointly act on the magnetic usage object, thereby increasing the adsorption force stability of the device when adsorbing the magnetic usage object. When adsorbing a non-magnetic usage object, the negative pressure assembly can still apply a force to it. In this setting method, the applicability of the device can be improved, thus avoiding frequent replacement of the adsorption mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0017] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0018] In order to better understand the purpose, structure and function of the present invention, a kind of adsorption device and its control system of the present invention will be further described in detail below with reference to the drawings.

[0019] Figure 1 、 2 Schematically shows the overall structure of an adsorption device according to the invention. As in Figure 1 、 2 In the shown embodiment, the adsorption device 100 includes an upper cover body 1 and a lower cover body 2 that is snap-connected to the upper cover body 1. In this way, the upper cover body 1 and the lower cover body 2 can jointly form a mounting cavity 3. Among them, as Figure 5 shown, a permanent magnetic adsorption mechanism 4 is further provided in the mounting cavity 3. The permanent magnetic adsorption mechanism 4 is made of a permanent magnet and is used to adsorb a ferromagnetic object to be used (not shown in the figure).

[0020] In this way, when the device 100 needs to adsorb a ferromagnetic object to be used, the device 100 can be arranged on the ferromagnetic object to be used, and the lower cover body 2 is made to fit with the ferromagnetic object to be used. In this setting mode, the permanent magnetic adsorption mechanism 4 will continuously apply a force to the ferromagnetic object to be used. Thus, the device 100 can be relatively fixed to the ferromagnetic object to be used, thereby realizing the adsorption of the ferromagnetic object to be used.

[0021] In one embodiment, as Figure 4 shown, a mounting groove 21 penetrating the lower cover body 2 is provided on the lower cover body 2, and the mounting groove 21 corresponds to the permanent magnetic adsorption mechanism 4. In this way, it can be avoided that when the permanent magnetic adsorption mechanism 4 applies a force towards the ferromagnetic object to be used, the lower cover body 2 consumes the force. Thus, the adsorption performance of the permanent magnetic adsorption mechanism 4 can be improved.

[0022] According to a preferred embodiment of the present invention, as Figure 4 shown, two installation grooves 21 are provided and distributed on the lower cover body 2 in a corresponding manner. It should be noted that two permanent magnet adsorption mechanisms 4 are also provided, and each permanent magnet adsorption mechanism 4 corresponds to the installation groove 21 respectively. In this way, when it is necessary to adsorb a ferromagnetic object to be used by the device 100, the two permanent magnet adsorption mechanisms 4 can act on the ferromagnetic object to be used together, thereby enhancing the adsorption ability of the device 100 to the ferromagnetic object to be used.

[0023] In one embodiment, as Figure 4 shown, the permanent magnet adsorption mechanism 4 is composed of a plurality of strip-shaped permanent magnets 41 arranged in a Halbach array to increase the magnetic force on the adsorption side of the permanent magnet adsorption mechanism 4. It should be noted that the Halbach array is well known to those skilled in the art. Therefore, it will not be elaborated here.

[0024] In one embodiment, as Figure 5 shown, the adsorption device 100 further includes an electromagnetic adsorption mechanism 5. In this embodiment, the electromagnetic adsorption mechanism 5 includes an electromagnet 51 disposed in the cavity 3 and a power supply assembly 52 connected to the electromagnet 51 through a wire (not shown in the figure) for supplying power to the electromagnet 51.

[0025] In this way, when the power supply assembly 52 operates and continuously supplies power to the electromagnet 51, the electromagnet 51 can be activated to generate magnetic force. In this setting mode, the electromagnet 51 can adsorb the ferromagnetic object to be used. However, when the power supply from the power supply assembly 52 to the electromagnet 51 is cancelled, the magnetic force generated by the electromagnet 51 can disappear. Thus, the adsorption of the ferromagnetic object to be used by the electromagnet 51 can be cancelled.

[0026] In this setting mode, when it is necessary to adsorb a ferromagnetic object to be used, the device 100 is placed on the ferromagnetic object to be used, and the lower cover body 2 is made to fit with the ferromagnetic object to be used. At this time, the permanent magnet adsorption mechanism 4 will continuously exert a force on the ferromagnetic object to be used.

[0027] Meanwhile, the power supply assembly 52 is activated. At this time, the power supply assembly 52 will continuously supply power to the electromagnet 51, so that the electromagnet 51 is activated and then generates magnetic force. In this way, the forces generated by the permanent magnet adsorption mechanism 4 and the electromagnet 51 can act on the ferromagnetic object to be used together, thereby realizing the adsorption of the ferromagnetic object to be used. Thus, the force generated when the device 100 adsorbs the ferromagnetic object to be used can be further increased, and then the ferromagnetic object to be used can be stably adsorbed.

[0028] In one embodiment, as Figure 4 shown, an installation opening 22 penetrating through the lower cover body 2 is further provided on the lower cover body 2, and the installation opening 22 corresponds to the electromagnet 51. In this way, when the electromagnet 51 applies a force to the ferromagnetic object to be used, the lower cover body 2 can be prevented from consuming the force. Thus, the adsorption performance of the electromagnet 51 can be improved.

[0029] According to a preferred embodiment of the present invention, as Figure 4 shown, two installation openings 22 are provided and are distributed on the lower cover body 2 in a corresponding manner. It should be noted that two electromagnets 51 are also provided, and each electromagnet 51 corresponds to the installation opening 22 respectively. In this way, when it is necessary to adsorb the ferromagnetic object to be used through the device 100, the two electromagnets 51 can act on the ferromagnetic object to be used together, thereby enhancing the adsorption ability of the device 100 to the ferromagnetic object to be used.

[0030] In one embodiment, as Figure 5 shown, the permanent magnet adsorption mechanism 4 and the electromagnet 51 are arranged in the installation cavity 3 in a perpendicular manner. Specifically, the two permanent magnet adsorption mechanisms 4 are arranged along the axis of the installation cavity 3, and the two permanent magnet adsorption mechanisms 4 are respectively located on both sides of the installation cavity 3, while the electromagnet 51 is arranged along the radial direction of the installation cavity 3, and the two permanent magnet adsorption mechanisms 4 are respectively located on both sides of the installation cavity 3.

[0031] In this way, the forces generated by the two permanent magnet adsorption mechanisms 4 and the two electromagnets 51 can form a rectangle. Thus, the adsorption ability of the device 100 can be further improved.

[0032] According to a preferred embodiment of the present invention, as Figure 5 shown, on the upper housing 1, first receiving grooves 11 are respectively provided on both sides in the axial direction, and the first receiving grooves 11 are configured to allow several bar-shaped permanent magnets 41 to be placed. In this way, several bar-shaped permanent magnets 41 can be stably arranged in the installation cavity 3.

[0033] Meanwhile, as Figure 5 shown, on the upper housing 1, second receiving grooves 12 are respectively provided on both sides in the radial direction, and the second receiving grooves 12 are configured to allow the electromagnets 51 to be placed. In this way, the two electromagnets 51 can be stably arranged in the installation cavity 3.

[0034] In addition, as Figure 5As shown, on the upper housing 1, a third receiving groove 13 is further provided, and the third receiving groove 13 is configured to allow the placement of the power supply component 52. In this way, the power supply component 52 can be stably arranged in the installation cavity 3. In this embodiment, the power supply component 52 is composed of a lithium battery.

[0035] In one embodiment, as Figure 2 , 4 shown, the adsorption device 100 further includes a negative pressure adsorption mechanism 6. In this embodiment, the negative pressure adsorption mechanism 6 includes an elastic part 61 provided on the lower cover body 2 and hermetically connected to the lower cover body 2. In the illustrated embodiment, the elastic part 61 is arranged along the contour of the lower cover body 2. In this way, the elastic part 61 and the lower cover body 2 can jointly form a circumferentially sealed vacuum chamber 62. It should be noted that the elastic part 61 is made of a material that allows elastic deformation, such as rubber.

[0036] Meanwhile, as Figure 5 shown, the negative pressure adsorption mechanism 6 further includes a negative pressure component 63 arranged in the installation cavity 3. In this embodiment, the negative pressure mechanism 63 is configured to be interconnected with the power supply component 52. In this way, the negative pressure component 63 can be selectively activated.

[0037] In addition, in the illustrated embodiment, as Figure 5 shown, the negative pressure component 63 is also arranged to communicate with the vacuum chamber 62. In this setting, when the negative pressure component 63 is activated, the vacuum chamber 62 can be evacuated. Specifically, when the power supply component 52 continuously supplies power to the negative pressure component 63, the negative pressure component 63 will be in an open state.

[0038] In this setting, when it is necessary to adsorb a ferromagnetic object to be used, the device 100 is arranged on the ferromagnetic object to be used, and the elastic part 61 located on the lower cover body 2 is brought into abutment with the ferromagnetic object to be used. At this time, the permanent magnet adsorption mechanism 4 will continuously exert a force on the ferromagnetic object to be used.

[0039] Meanwhile, the power supply component 52 is activated, and the power supply component 52 supplies power to the electromagnet 51 and the negative pressure component 63 respectively. During this process, the electromagnet 51 and the negative pressure component 63 will be activated respectively. At this time, the forces generated by the permanent magnet adsorption mechanism 4 and the electromagnet 51 will act on the ferromagnetic object to be used jointly.

[0040] In addition, during this process, the negative pressure component 63 will continuously evacuate the vacuum chamber 62. At this time, as the negative pressure component 6 continuously evacuates the vacuum chamber 62, the elastic part 61 will continuously undergo elastic deformation and fit together with the ferromagnetic object to be used, thereby adsorbing the ferromagnetic object to be used. In this way, when the device 100 adsorbs the ferromagnetic object to be used, the ferromagnetic object to be used can be subjected to the combined action of the permanent magnet adsorption mechanism 4, the electromagnet 51, and the negative pressure component 63. Therefore, the ability of the device 100 to adsorb the ferromagnetic object to be used can be further improved.

[0041] However, when the object adsorbed by the device 100 is a non-ferromagnetic object to be used, the negative pressure component 63 can still apply a force to the object, thereby realizing the adsorption of the non-ferromagnetic object to be used.

[0042] In one embodiment, as Figure 5 shown, the negative pressure component 63 includes a negative pressure pump 631 for allowing air extraction, and a one-way valve 632 provided at the air extraction end of the negative pressure pump 631 and allowing communication with the negative pressure pump 631 when the negative pressure pump 631 is performing air extraction work. In this setting, after the negative pressure pump 631 completes the air extraction work on the vacuum chamber 62, the pressure in the vacuum chamber 62 can be maintained by the one-way valve 632, thereby preventing the negative pressure pump 631 from continuously working to maintain the vacuum environment in the vacuum chamber 62. In this way, the energy consumption of the device 100 can be reduced.

[0043] According to a preferred embodiment of the present invention, as Figure 5 shown, on the upper housing 1, a fourth receiving groove 14 is further provided, and the fourth receiving groove 14 is configured to allow the placement of the negative pressure pump 631 and the one-way valve 632 communicating with the negative pressure pump 631.

[0044] Meanwhile, as Figure 4 shown, a through hole 23 allowing communication with the air extraction end of the negative pressure pump 631 is further provided on the lower housing 2. In this way, a passage for extracting air into the vacuum chamber 62 can be jointly formed between the through hole 23 and the negative pressure pump 631, so that the gas in the vacuum chamber 62 can move along the passage, and thus the vacuum chamber 62 can adsorb the object to be used (ferromagnetic object to be used and non-ferromagnetic object to be used).

[0045] In the illustrated embodiment, as Figure 4 shown, a waterproof and breathable membrane 231 is further covered on the through hole 23. In this way, when the negative pressure pump 631 extracts air from the vacuum chamber 62, it can prevent the fluid in the vacuum chamber 62 from entering the negative pressure pump 631 along the through hole 23, so as to reduce the service life of the negative pressure pump 631.

[0046] In one embodiment, as Figure 2 、 6 shown, the adsorption device 100 further includes a control system 10. The control system 10 includes a control board 101 connected to the power supply component 52, and a Hall inductor 102 that penetrates through the lower cover 2 and allows receiving signals from the control board 101, and then starts in a selective manner.

[0047] It should be noted that the Hall inductor 102 can sense a ferromagnetic object to be used. When the relative distance between the Hall inductor 102 and the ferromagnetic object to be used reaches a certain degree, the Hall inductor 102 can identify the ferromagnetic object to be used. It should be noted that the manner in which the Hall inductor 102 senses the ferromagnetic object to be used and at what distance from the ferromagnetic object to be used it can identify the ferromagnetic object to be used is well known to those skilled in the art. Therefore, it will not be elaborated here.

[0048] Among them, as Figure 6 、 8 shown, the control board 101 is configured to allow the power supply component 52 to be turned on when receiving a signal transmitted by the Hall inductor 102, and to continuously supply power to the electromagnet 51 by the power supply component 52. In this way, the electromagnet 51 is turned on, thereby generating a magnetic force to adsorb the ferromagnetic object to be used.

[0049] In one embodiment, as Figure 6 、 9 shown, the control system 10 further includes a vacuum pressure sensor 103 connected to the control board 101. In this embodiment, the vacuum pressure sensor 103 is configured to continuously monitor the vacuum pressure in the vacuum chamber 62 and allow the monitored pressure information to be continuously transmitted to the control board 101, so that the control board 101 can selectively turn on the operation of the power supply component 52 to supply power to the negative pressure pump 631 according to the received pressure information, and then the negative pressure pump 631 can selectively evacuate the vacuum chamber 62.

[0050] It should be noted that the vacuum pressure sensor 103 is provided with a threshold value. Specifically, when the vacuum pressure in the vacuum chamber 62 reaches the upper limit value of the vacuum pressure sensor 103, the control board 101 will disconnect the operation of the power supply component 52 to supply power to the negative pressure pump 631, and then the one-way valve 632 will maintain the vacuum pressure in the vacuum chamber 62. As the vacuum pressure in the vacuum chamber 62 continues to drop, when the vacuum pressure drops to the lower limit value, the control board 101 will start the operation of the power supply component 52 to supply power to the negative pressure pump 631, so that the vacuum pressure in the negative pressure pump 631 continues to rise to meet the adsorption of the objects to be used (magnetic objects to be used and non-magnetic objects to be used).

[0051] According to a preferred embodiment of the present invention, as Figure 9 shown, the control system 10 further includes a vacuum-breaking valve 104 connected to the control board 101 and communicating with the vacuum chamber 42. The vacuum-breaking valve 104 is configured to allow the vacuum environment formed in the vacuum chamber 62 to be destroyed in a selective manner, so that the vacuum chamber 62 is balanced with the atmospheric pressure outside. In this way, the adsorption of the object to be used by the vacuum chamber 62 is cancelled. It should be noted that when the control board 101 activates the vacuum-breaking valve 104, the power supply component 52 and the negative pressure pump 631 are in an open circuit state.

[0052] In one embodiment, as Figure 6 、 7 shown, the control system 10 further includes proximity sensors 105 connected to the control board 101 and distributed on the lower cover 2 in a pairwise opposite manner. The proximity sensors 105 are configured to be able to identify the flatness of the objects to be used (magnetic objects to be used and non-magnetic objects to be used), and allow the identified information to be continuously transmitted to the control board 101.

[0053] At the same time, as Figure 6 shown, the control system 10 further includes a buzzer 106 connected to the control board 101 and the power supply component 52 respectively. In this embodiment, the control board 101 is configured to allow the power supply component 52 to supply power to the buzzer 106 when the information transmitted by the four proximity sensors 105 is not received, and then activate the buzzer 106 to alarm.

[0054] In addition, in the illustrated embodiment, as Figure 6 shown, the control board 101 is further configured to allow continuous monitoring of the power of the power supply component 52, and when its power is lower than a certain percentage, the control board 101 allows the power supply component 52 to supply power to the buzzer 106, and then activates the buzzer 106 to alarm.

[0055] According to a preferred embodiment of the present invention, as Figure 8As shown, the control board 101 is also configured such that as the Hall sensor 102 continuously approaches the object to be used, when the relative distance between the Hall sensor 102 and the object to be used reaches the threshold value of the Hall sensor 102 and no ferromagnetic object to be used is recognized, the control board 101 performs an operation of not supplying power to the electromagnet 51 by the power supply component 52. Specifically, when the Hall sensor 102 does not recognize a ferromagnetic object to be used, the electromagnet 51 is not activated.

[0056] Meanwhile, as Figure 9 shown, the control board 101 is also configured such that when the negative pressure pump 631 continuously pumps air from the vacuum chamber 62 and the vacuum pressure in the vacuum chamber 62 still does not reach the upper limit value of the vacuum pressure sensor 103, the control board 101 allows the power supply component 52 to supply power to the buzzer 106, thereby activating the buzzer 106 to give an alarm.

[0057] In one embodiment, as Figure 1 、 6 shown, the adsorption device 100 further includes a start button 20. In this embodiment, the start button 20 is set to be connected to the control board 101 in a wired or wireless manner to turn on the control board 101 and thus start the device 100.

[0058] In this setting mode, when it is necessary to use the device 100 to adsorb an object to be used (ferromagnetic object to be used and non-ferromagnetic object to be used), first move the device 100 to the object to be used. Meanwhile, operate the start button 20 to start the device 100.

[0059] During this process, the proximity sensor 105 will identify the object to be used. When the object to be used cannot fully cover the proximity sensor 105, the control board 101 will allow the power supply component 52 to supply power to the buzzer 106, thereby activating the buzzer 106 to give an alarm. During this process, the staff can adjust the placement position of the device 100 or replace the object to be used according to the information prompt generated by the alarm.

[0060] When the object to be used can fully cover the proximity sensor 105, at this time the control board 101 will activate the Hall sensor 102. During this process, the Hall sensor 102 will identify the material of the object to be used. If the object to be used is made of iron, the Hall sensor 102 will then feed back the information to the control board 101.

[0061] During this process, the control board 101 will initiate the operation of continuously powering the electromagnet 51 by the power supply component 52. In this way, the electromagnet 51 is turned on, generating a magnetic force to adsorb the ferromagnetic object to be used. It should be noted that during this process, the permanent magnet adsorption mechanism 4 will also apply an adsorption force to the iron object to be used, so that the iron object to be used can be subjected to the adsorption forces jointly exerted by the bar permanent magnet 41 and the electromagnet 51.

[0062] However, during this process, when the Hall sensor 102 fails to recognize the ferromagnetic object to be used, the control board 101 will not start the operation of powering the electromagnet 51 by the power supply component 52, thus saving the power of the power supply component 51.

[0063] Moreover, during this process, the control board 101 will also initiate the operation of powering the negative pressure pump 631 by the power supply component 52, so that the negative pressure pump 631 pumps air out of the vacuum chamber 62 until the vacuum pressure in the vacuum chamber 62 reaches the upper limit value of the vacuum pressure sensor 103. At this time, the control board 101 will disconnect the operation of powering the negative pressure pump 631 by the power supply component 52, and then the one-way valve 632 will maintain the vacuum pressure in the vacuum chamber 62.

[0064] As the vacuum pressure in the vacuum chamber 62 continues to drop, when the vacuum pressure drops to the lower limit value, the control board 101 will initiate the operation of powering the negative pressure pump 631 by the power supply component 52, so that the vacuum pressure in the negative pressure pump 631 continues to rise to meet the adsorption of the object to be used.

[0065] In addition, when the negative pressure pump 631 continuously pumps air out of the vacuum chamber 62, but the vacuum pressure in the vacuum chamber 62 still fails to reach the upper limit value of the vacuum pressure sensor 103, the control board 101 allows the power supply component 52 to power the buzzer 106, and then activates the buzzer 106 to alarm.

[0066] In this way, when the device 100 adsorbs the ferromagnetic object to be used, the bar permanent magnet 41, the electromagnet 51, and the vacuum chamber 62 can jointly exert forces on the ferromagnetic object to be used, so that the device 100 can stably adsorb the ferromagnetic object to be used. However, when the device 100 adsorbs a non-ferromagnetic object to be used, the vacuum chamber 62 will be able to exert a force on the part to meet the adsorption requirements for the object to be used.

[0067] When the adsorption of the object to be used is completed and it is necessary to cancel the force exerted on the object to be used by the device 100, the start button 20 is operated again. At this time, the control board 101 will activate the vacuum-breaking valve 104 that communicates with the vacuum chamber 42, so that the vacuum chamber 62 is balanced with the atmospheric pressure outside, thereby canceling the adsorption of the vacuum chamber 62 to the object to be used.

[0068] Meanwhile, during this process, the control board 101 will cancel the operation of the power supply component 52 to supply power to the electromagnet 51, so that the electromagnet 51 does not generate magnetic force, thereby canceling the adsorption of the electromagnet to the ferromagnetic object to be used. Thus, the adsorption of the object to be used and the cancellation of the adsorption of the object to be used are realized.

[0069] According to a preferred embodiment of the present invention, as Figure 3 shown, a connecting portion 15 is provided on the upper cover 1, and the connecting portion 15 is configured to allow the device 100 to be connected to a support device (not shown in the figure). It should be noted that the connecting portion 15 is not the focus of this design improvement in this embodiment. Therefore, it will not be elaborated here.

[0070] According to a preferred embodiment of the present invention, as Figure 3 shown, a display screen 16 and an indicator light 17 are provided on the upper cover 1 and are respectively connected to the control board 101. The display screen 16 is configured to allow the display of the vacuum pressure in the vacuum chamber 62, while the indicator light 17 is configured to allow the display of the power of the power supply component 52.

[0071] The operation of the adsorption device 100 according to the present invention is as follows.

[0072] When it is necessary to use the device 100 to adsorb an object to be used (ferromagnetic object to be used and non-ferromagnetic object to be used), first connect the device 100 to a support device (not shown in the figure), and move the device 100 to the object to be used through the support device. At the same time, the start button 20 is operated to start the device 100. At this time, the indicator light 17 will continuously display the power of the power supply component 52. When the power of the power supply component 52 is less than the set percentage, the control board 101 will activate the buzzer 106 to make the buzzer 106 emit an information prompt.

[0073] Meanwhile, during the process of the device 100 continuously approaching the object to be used, the proximity sensor 105 will identify the object to be used. When the proximity sensor 105 cannot fully identify the object to be used, the control board 101 will activate the buzzer 106, so that the buzzer 106 emits an information prompt, and then the staff will adjust the placement position of the device 100 or replace the object to be used according to the information prompt generated by the alarm.

[0074] When the object to be used can fully cover the proximity sensor 105, the control board 101 will activate the Hall sensor 102 at this time. During this process, the Hall sensor 102 will identify the material of the object to be used. If the object to be used is made of iron, the control board 101 will start the operation of continuously supplying power to the electromagnet 51 by the power supply component 52. In this way, the electromagnet 51 is turned on, generating a magnetic force to adsorb the ferromagnetic object to be used.

[0075] When the Hall sensor 102 does not detect a ferromagnetic object to be used, the control board 101 will not start the operation of supplying power to the electromagnet 51 by the power supply component 52, thus saving the power of the power supply component 51.

[0076] Moreover, during this process, the control board 101 will also start the operation of supplying power to the negative pressure pump 631 by the power supply component 52, so that the negative pressure pump 631 evacuates the vacuum chamber 62 until the vacuum pressure in the vacuum chamber 62 reaches the upper limit value of the vacuum pressure sensor 103. At this time, the control board 101 will disconnect the operation of supplying power to the negative pressure pump 631 by the power supply component 52, and then the one-way valve 632 will maintain the vacuum pressure in the vacuum chamber 62. During this process, the display screen 16 will also continuously display the vacuum pressure in the vacuum chamber 62.

[0077] As the vacuum pressure in the vacuum chamber 62 continuously decreases, when the vacuum pressure drops to the lower limit value, the control board 101 will start the operation of supplying power to the negative pressure pump 631 by the power supply component 52, so that the vacuum pressure in the negative pressure pump 631 continuously rises to meet the adsorption of the object to be used.

[0078] When the negative pressure pump 631 continuously evacuates the vacuum chamber 62, but the vacuum pressure in the vacuum chamber 62 still does not reach the upper limit value of the vacuum pressure sensor 103, the control board 101 allows the power supply component 52 to supply power to the buzzer 106, and then starts the buzzer 106 to alarm.

[0079] When the adsorption of the object to be used is completed and it is necessary to cancel the force exerted on the object to be used by the device 100, the start button 20 is operated again. At this time, the control board 101 will activate the vacuum-breaking valve 104 that communicates with the vacuum chamber 42, so that the vacuum chamber 62 is balanced with the atmospheric pressure outside, and then the adsorption of the vacuum chamber 62 on the object to be used is cancelled.

[0080] At the same time, during this process, the control board 101 will cancel the operation of supplying power to the electromagnet 51 by the power supply component 52, so that the electromagnet 51 does not generate a magnetic force, thereby canceling the adsorption of the electromagnet on the ferromagnetic object to be used. Thus, the adsorption of the object to be used and the cancellation of the adsorption of the object to be used are realized.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
