Description

Technical Field

[0001] The present disclosure relates to the field of electronic technology, and in particular to a control device. Background Art

[0002] In the production process of electronic devices, adhesives are usually used to bond some materials in the electronic devices. For example, after the assembly of the display screen and the middle frame is completed, the contact position of the display screen and the middle frame is bonded by adhesive. In the process of bonding some materials in the electronic device by adhesive, the bonded materials can also be pressure-maintained by a magnetic pressure-maintaining device to reduce the gap between the two materials to be bonded and increase the firmness of the material bonding.

[0056] refer to Figures 1 to 5 , Figure 1 is a structural schematic diagram of a control device according to an exemplary embodiment; Figure 2 is a structural schematic diagram of a magnetic power module according to an exemplary embodiment; Figure 3 is a schematic structural diagram of a driving module according to an exemplary embodiment; Figure 4 is a schematic structural diagram of a second positioning member according to an exemplary embodiment; Figure 5 FIG. 1 is a schematic diagram showing a structure of a support portion with a magnetic power module installed according to an exemplary embodiment. Figures 1 to 5, the control device provided in the embodiment of the present disclosure is introduced.

[0057] In some embodiments, Figures 1 to 5 As shown, an embodiment of the present disclosure provides a control device, including:

[0058] At least one magnetic power module 10, the magnetic power module 10 comprises:

[0059] A first positioning member 101;

[0060] The first driving assembly is connected to the first positioning member 101 and is used to drive the first positioning member 101 to drive the magnetic member to rotate when the first positioning member 101 is engaged with the magnetic member in the pressure-maintaining device.

[0061] It can be understood that there is at least one group of magnetic parts in the pressure-maintaining device, wherein one group of magnetic parts includes a first magnetic part and a second magnetic part. When the magnetic pole directions of the first magnetic part and the second magnetic part are the same, the first magnetic part and the second magnetic part attract each other, and then pressure can be applied to the material between the first magnetic part and the second magnetic part, that is, the material between the first magnetic part and the second magnetic part is pressure-maintained. When the magnetic pole directions of the first magnetic part and the second magnetic part in a group of magnetic parts are opposite, the first magnetic part and the second magnetic part repel each other, and the pressure on the material between the first magnetic part and the second magnetic part can be relieved.

[0062] Based on this, when it is necessary to apply pressure to the material, the first positioning member 101 in the magnetic power module 10 can be clamped with the first magnetic member or the second magnetic member in the pressure maintaining device, and the first positioning member 101 can be driven to rotate by the first driving component, thereby driving the first magnetic member or the second magnetic member clamped with the first positioning member 101 to rotate, so that the magnetic poles of the first magnetic member and the second magnetic member are in the same direction, thereby causing the first magnetic member and the second magnetic member to attract each other, thereby achieving pressure on the material.

[0063] When it is necessary to release the pressure applied to the material by the first magnetic member and the second magnetic member, the first positioning member 101 can be clamped with the first magnetic member or the second magnetic member, and the first magnetic member or the second magnetic member clamped with the first positioning member 101 can be driven to rotate so that the magnetic pole directions of the first magnetic member and the second magnetic member change from the same to the opposite, so that the first magnetic member and the second magnetic member can change from a mutually attractive state to a mutually repelling state to release the pressure applied to the material by the first magnetic member and the second magnetic member.

[0064] In the following, the working process of the control device will be described by taking the engagement of the first positioning member with the first magnetic member in the pressure-maintaining device as an example. In addition, the process of driving the first magnetic member to rotate by the control device provided in the embodiment of the present disclosure so that the first magnetic member and the second magnetic member in a group of magnetic members attract each other can be understood as magnetizing the pressure-maintaining device, and the process of driving the first magnetic member to rotate by the control device provided in the embodiment of the present disclosure so that the first magnetic member and the second magnetic member in a group of magnetic members repel each other can be understood as demagnetizing the pressure-maintaining device.

[0065] In some embodiments, the number of magnetic power modules 10 included in the control device can be set as needed, and the embodiments of the present disclosure are not limited to this.

[0066] Exemplarily, the number of magnetic power modules 10 included in the control device can be set according to the number of magnetic component groups in the pressure maintaining device.

[0067] For example, when there are two groups of magnetic components in the magnetic power module 10, two magnetic power modules can be arranged in the control device, wherein one magnetic power module is used to control the rotation direction of the first magnetic component in a group of magnetic components.

[0068] In some embodiments, the first positioning member 101 may be directly engaged with the first magnetic member in the pressure-maintaining device, or may be indirectly engaged with the first magnetic member in the pressure-maintaining device, which is not limited in the embodiments of the present disclosure.

[0069] For example, the first magnetic member in the pressure-maintaining device can be fixed on the connecting member, and when the first magnetic member in the pressure-maintaining device needs to be controlled to rotate by the control device, the first positioning member 101 in the magnetic power module 10 can be clamped with the connecting member. Based on this, when the first driving component drives the first positioning member 101 to rotate, the connecting member and the first magnetic member fixed on the connecting member can be driven to rotate, thereby changing the relative direction between the magnetic poles of the first magnetic member and the magnetic poles of the second magnetic member.

[0070] In some embodiments, the shape of the first positioning member 101 can be any shape that can be directly or indirectly engaged with the first magnetic member in the pressure-maintaining device, and the embodiments of the present disclosure are not limited to this.

[0071] Exemplarily, the first positioning member 101 may be in the shape of a gear or a cylinder with one or more protrusions on the side wall.

[0072] In some embodiments, the size of the first positioning member 101 can be determined according to the size of the first magnetic member. When the size of the first magnetic member is large, the first positioning member 101 can be designed to be large, and when the size of the first magnetic member is small, the first positioning member 101 can also be designed to be small.

[0073] In some embodiments, considering that the first positioning member 101 will be driven by the driving force of the motor 103 during the process of driving the first magnetic member to rotate, a material with a certain hardness and not adsorbed by the first magnetic member can be selected when manufacturing the first positioning member 101. For example, the material for manufacturing the first positioning member 101 can be a metal material, alloy material, hard resin material, ceramic material, etc. that will not be adsorbed by the first magnetic member.

[0074] In some embodiments, reference Figure 2 A connecting shaft 102 may be further provided between the first driving assembly and the first positioning member 101 , and the first positioning member 101 may be connected to the power output end of the driving module 20 through the connecting shaft 102 .

[0075] In some embodiments, the first driving component can be a motor 103, and the first positioning member 101 can be directly connected to the first rotating shaft of the motor 103, or can be connected to the first rotating shaft of the motor 103 through the connecting shaft 102. Based on this, when the first positioning member 101 is engaged with the first magnetic member in the pressure-maintaining device, the motor 103 can be started, and the first rotating shaft of the motor 103 can be rotated to drive the first positioning member 101 to rotate, thereby driving the first magnetic member connected to the first positioning member 101 to rotate, so as to change the magnetic pole reversal of the first magnetic member.

[0076] In the embodiment of the present disclosure, the control device includes one or more magnetic power modules, and the first positioning member on each magnetic power module can be engaged with the corresponding first magnetic member on the pressure maintaining device, and the first positioning member is driven by the first driving component to drive the first magnetic member engaged with the first positioning member to rotate, so as to change the magnetic pole direction of the first magnetic member, thereby achieving the purpose of automatically magnetizing or demagnetizing the pressure maintaining device. This can increase the degree of automation in the production of electronic equipment and thereby improve the production efficiency of electronic equipment.

[0077] In some embodiments, the first drive assembly includes:

[0078] The motor 103 has a first rotating shaft;

[0079] The speed reducer 104 has a second rotating shaft and a third rotating shaft which are arranged opposite to each other. The speed reducer 104 is connected to the first rotating shaft via the second rotating shaft, and the speed reducer 104 is connected to the first positioning member 101 via the third rotating shaft.

[0080] When the motor 103 drives the second rotating shaft to rotate at a first speed through the first rotating shaft, the third rotating shaft drives the first positioning member 101 to rotate at a second speed, and the second speed is lower than the first speed.

[0081] It is understandable that, considering that the rotation speed of the motor 103 is usually fast, therefore, when the first drive assembly includes the motor 103, a reduction member 104 can be provided between the first rotating shaft of the motor 103 and the first positioning member 101, and the second rotating shaft of the reduction member 104 is connected to the first rotating shaft of the motor 103, and the third rotating shaft of the reduction member 104 is connected to the first positioning member 101. Based on this, when the first rotating shaft of the motor 103 rotates at the first rotating speed, the second rotating shaft of the reduction member 104 can be driven to rotate at the first rotating speed. The reduction member 104 can reduce the first rotating speed of the second rotating shaft to the second rotating speed, and output it through the third rotating shaft, that is, the reduction member 104 can output the second rotating speed through the third rotating shaft when the rotating speed of the second rotating shaft is the first rotating speed, thereby driving the first positioning member 101 connected to the third rotating shaft to rotate at the second rotating speed, thereby achieving the purpose of reducing the rotating speed of the first positioning member 101.

[0082] In some embodiments, the speed reducer 104 is connected to the first positioning member 101 via a third rotating shaft, including: the first positioning member 101 is directly connected to the third rotating shaft of the speed reducer 104, or the first positioning member 101 is indirectly connected to the third rotating shaft of the speed reducer 104 via a connecting shaft 102.

[0083] In some embodiments, the model of the motor included in the first drive assembly can be selected as needed, and the embodiments of the present disclosure are not limited to this.

[0084] Exemplarily, the motor 103 included in the first driving assembly may be a closed-loop stepping motor.

[0085] In some embodiments, the above-mentioned speed reducer 104 can be any speed reducer 104 that can reduce the rotation speed of the first rotating shaft of the motor 103, and the embodiments of the present disclosure are not limited to this.

[0086] Exemplarily, the above-mentioned speed reducer 104 can be a ratio reducer, a harmonic reducer, a worm gear reducer, a planetary reducer, etc.

[0087] In the disclosed embodiment, when the pressure-maintaining device is demagnetized or magnetized, the first positioning member 101 drives the first magnetic member to rotate 180° to change the magnetic pole direction of the first magnetic member. Therefore, if the rotation speed of the motor 103 is too high, it will increase the difficulty of controlling the rotation angle of the first magnetic member, and will also increase the interaction force between the first positioning member 101 and the first magnetic member, causing damage to the first positioning member 101 and the first magnetic member. By adding a speed reducer 104 between the first rotating shaft of the motor 103 and the first positioning member 101, the rotation speed of the first positioning member 101 can be controlled within the required range through the speed reducer 104, thereby more accurately controlling the rotation angle of the first magnetic member. In addition, reducing the rotation speed of the first positioning member 101 can also reduce the interaction force between the first positioning member 101 and the first magnet, thereby reducing the probability of damage to the first positioning member and the first magnetic member due to excessive interaction between the first positioning member 101 and the first magnetic member.

[0088] In some embodiments, the apparatus further comprises:

[0089] A driving module 20 connected to at least one magnetic power module 10;

[0090] The driving module 20 drives the magnetic power module 10 to approach the pressure-maintaining device, and the first positioning member 101 is inserted into the first groove formed by the depression of the magnetic member, or;

[0091] The first positioning member 101 is inserted into a second groove formed by the depression of the connecting member on the pressure-maintaining device, and the connecting member is fixedly connected to the magnetic member.

[0092] It can be understood that a driving module 20 can also be provided on the control device of the embodiment of the present disclosure, and at least one magnetic power module 10 included in the control device can be connected to the driving module 20. Based on this, the magnetic power module 10 can move in a direction close to or away from the pressure-maintaining device under the drive of the driving module 20. In addition, a groove capable of being engaged with the first positioning member 101 is provided on the pressure-maintaining device, wherein the groove can be a first groove directly provided on the first magnetic member, or a second groove provided on a connecting member fixedly connected to the first magnetic member.

[0093] Based on this, when it is necessary to use the control device provided in the embodiment of the present disclosure to drive the first magnetic part in the pressure-maintaining device to rotate, the driving module 20 can drive the magnetic power module connected to the driving module 20 to move toward the direction close to the pressure-maintaining device until the first positioning member 101 on the magnetic power module 10 is inserted into the first groove or the second groove, so that the first positioning member 101 is engaged with the first magnetic part. After completing the rotation of the first magnetic part, the driving module 20 can also drive the magnetic power module 10 away from the pressure-maintaining device until the first positioning member 101 is completely out of the first groove or the second groove.

[0094] In some embodiments, the driving module 20 may be any driving module 20 that can drive the magnetic power module 10 to move, and the embodiment of the present disclosure does not limit the type of the driving module.

[0095] Exemplarily, the driving module 20 may be a hydraulic lifting device connected to the magnetic power module 10 , a lifting device composed of a motor 103 and a screw rod, a lifting device composed of a pulley and a motor 103 , and the like.

[0096] In some embodiments, a magnetic power module 10 is disposed on a driving module 20 .

[0097] In other embodiments, all magnetic power modules 10 included in the control device can be arranged on the same driving module 20 .

[0098] In some embodiments, the connecting member fixedly connected to the first magnetic member in the pressure maintaining device may be a connecting plate fixed on a surface of the first magnetic member, or may be a shell capable of covering at least a portion of the first magnetic member.

[0099] In some embodiments, when the first positioning member 101 is connected to the first driving assembly via the connecting shaft 102 , the length of the connecting shaft 102 may also be determined according to the depth of the first groove or the second groove.

[0100] In some embodiments, the first positioning member 101 includes:

[0101] The body 1011 is connected to the first driving assembly;

[0102] A first limiting block 1012 is provided on a side wall of the body 1011;

[0103] When the first driving assembly drives the main body 1011 to drive the first limiting block 1012 to rotate to align with the alignment portion in the first groove or the alignment portion in the second groove, the driving module 20 drives the magnetic power module 10 to approach the pressure maintaining device.

[0104] It can be understood that the first positioning member 101 is composed of two parts, one part is the body 1011 of the first positioning member 101, and the other part is the first limit block 1012 arranged on the body 1011 of the first positioning member 101. In addition, there is a positioning portion for accommodating the first limit block 1012 in the first groove or the second groove of the pressure-maintaining device. Based on this, when it is necessary to use the control device provided in the embodiment of the present disclosure to magnetize or demagnetize the pressure-maintaining device, the driving module 20 can drive the magnetic power module 10 to move in the direction close to the pressure-maintaining device until there is a preset distance between the first positioning member 101 and the pressure-maintaining device. Afterwards, the first driving component drives the main body 1011 of the first positioning member 101 to drive the first limiting block 1012 to rotate until the first limiting block 1012 on the first positioning member 101 is aligned with the alignment part in the first groove or the second groove, and then drives the first positioning member 101 to be inserted into the first groove or the second groove through the driving module 20, so that the first positioning member 101 is clamped into the alignment part of the first groove or the second groove through the first limiting block 1012, thereby realizing the clamping connection between the first positioning member 101 and the first magnetic member.

[0105] In some embodiments, the shape and number of the first limiting blocks 1012 on the first positioning member 101 can be set according to the shape and number of the alignment parts in the first groove or the second groove on the pressure maintaining device.

[0106] For example, reference Figure 2 The body 1011 of the first positioning member 101 may be a cylindrical structure, and the first limiting block 1012 located on the side wall of the body 1011 of the first positioning member 101 may be a protrusion arranged on the side wall of the body 1011.

[0107] In some embodiments, the body 1011 of the first positioning member 101 and the first limiting block 1012 on the first positioning member 101 may be an integral structure or a separate structure, which is not limited in the embodiments of the present disclosure.

[0108] In some embodiments, when the first limit block 1012 and the main body 1011 of the first positioning member 101 are separate structures, the first limit block 1012 can be fixed to the main body 1011 of the first positioning member 101 from multiple directions by fixing members to increase the connection firmness between the first limit block 1012 and the main body 1011 of the first positioning member 101.

[0109] In some embodiments, the first driving assembly is used to drive the first positioning member 101 to drive the first magnetic member to rotate by a preset angle in the first direction to magnetize the pressure-holding device when the first positioning member 101 is inserted into the first groove or the second groove; or drive the first positioning member 101 to drive the first magnetic member to rotate by a preset angle in the second direction to demagnetize the pressure-holding device;

[0110] The first direction is opposite to the second direction.

[0111] It can be understood that when the driving module 20 drives the first positioning member 101 to be inserted into the first groove or the second groove, it means that the first positioning member 101 has completed the clamping connection with the first magnetic member. At this time, the first driving component can drive the first positioning member 101 to rotate by a preset angle along the first direction, thereby driving the first magnetic member connected to the first positioning member 101 to rotate by a preset angle along the first direction, so that the rotated first magnetic member and the second magnetic member opposite to the first magnetic member in the pressure-maintaining device have the same magnetic pole direction, thereby causing the first magnetic member and the second magnetic member to attract each other, thereby realizing the upper magnetization of the pressure-maintaining device. When it is necessary to demagnetize the pressure-maintaining device in the upper magnetization state, the first driving component can drive the first positioning member 101 to rotate by a preset angle along the second direction, so that the magnetic pole directions of the first magnetic member and the second magnetic member are opposite. At this time, the first magnetic member and the second magnetic member repel each other, thereby realizing the demagnetization of the pressure-maintaining device.

[0112] In some embodiments, the preset angle may be 180° or approximately 180°, wherein approximately 180° may be understood as any angle between 170° and 190°.

[0113] In some embodiments, if the first direction is clockwise, the second direction is counterclockwise; if the first direction is counterclockwise, the second direction is clockwise.

[0114] In some embodiments, the driving module 20 includes:

[0115] A first support plate, at least one magnetic power module 10 is arranged on the first support plate;

[0116] At least two second support plates 201, which are perpendicular to the first support plate and are clamped with the first support plate;

[0117] The second driving assembly 202 is connected to the first supporting plate and the second supporting plate 201 , and is used to drive the first supporting plate to drive at least one magnetic power module 10 to move in a direction parallel to the second supporting plate 201 .

[0118] It can be understood that the magnetic power module 10 may include a first support plate and at least two second support plates 201. Among them, the second support plates 201 are arranged below the first support plate and are perpendicular to the first support plate, and are used to support the first support plate. All magnetic power modules 10 included in the control device can be fixedly set on the first support plate. The second drive assembly 202 included in the drive module 20 can be fixed on the second support plate 201, and the power output end of the second drive assembly 202 is connected to the first support plate, which is used to drive the first support plate to move relative to the second support plate 201 in a direction close to or away from the pressure-maintaining device, thereby driving the magnetic power module 10 fixedly set on the first support plate to move in a direction close to or away from the pressure-maintaining device.

[0119] In some embodiments, when the control device includes multiple magnetic power modules 10, the multiple magnetic power modules 10 can be fixed on a first support plate at preset intervals, and the first positioning member 101 on the magnetic power module 10 is located on the side of the first support plate away from the second support plate 201.

[0120] In some embodiments, the size of the first support plate can be determined according to the number of magnetic power modules 10 to be arranged on the first support plate. When the number of magnetic power modules 10 to be arranged on the first support plate is large, a first support plate of larger size can be selected, and when the number of magnetic power modules 10 to be arranged on the first support plate is small, a first support plate of smaller size can be selected.

[0121] In some embodiments, the second support plate 201 may be disposed below the first support plate along the length direction or the width direction of the first support plate to support the first support plate.

[0122] The number of second support plates 201 can be determined according to the size of the first support plate. When the size of the first support plate is large, a larger number of second support plates 201 can be arranged below the first support plate to increase the balance of each second support plate 201 supporting the first support plate.

[0123] Exemplarily, when there are two second support plates 201 , the two second support plates 201 may be disposed below two opposite length sides of the first support plate, or the two second support plates 201 may be disposed below two opposite width sides of the first support plate.

[0124] In some embodiments, the second drive assembly 202 can be fixed on the side wall of the second support plate 201 and connected to the first support plate through the power output end to drive the first support plate to move toward or away from the pressure maintaining device relative to the second support plate 201, thereby driving the magnetic power module 10 located on the first support plate to move toward or away from the pressure maintaining device.

[0125] In some embodiments, the second drive assembly 202 may include a fixed end and a movable end, wherein the second drive assembly 202 may be fixed to the side wall of the second support plate 201 through the fixed end, and the movable end of the second drive assembly 202 is connected to the first support plate. Based on this, when the movable end of the second drive assembly 202 moves in a direction parallel to the second support plate 201 relative to the fixed end of the second drive assembly 202, the first support plate and the magnetic power module fixed on the first support plate may be driven to approach the pressure-maintaining device and to move away from the pressure-maintaining device.

[0126] In some embodiments, a second drive component 202 can be fixedly disposed on each second support plate 201, or a second drive component 202 can be disposed on each of two second support plates 201 that are disposed opposite to each other and are the farthest apart, so that the first support plate can maintain a horizontal state during the movement, thereby making the distance between each magnetic power module located on the first support plate and the pressure maintaining device the same or similar.

[0127] In some embodiments, the second drive assembly 202 may be a hydraulic lifting assembly or a sliding cylinder. When the second drive assembly 202 is a sliding cylinder, the second drive assembly 202 is a cylinder body of the sliding cylinder, and the movable end of the second drive assembly 202 is a slide plate of the sliding cylinder, wherein the slide plate and the cylinder body of the sliding cylinder are connected by a piston rod of the sliding cylinder.

[0128] In some embodiments, when the second drive component 202 includes a fixed end and a movable end, a third photoelectric sensor 203 may be provided at the first position of the movable end of the second drive component 202, and a fourth photoelectric sensor 204 may be provided at the second position of the second support plate 201 that fixes the second drive component 202. When the movable end of the second drive component 202 drives the first positioning member 101 on the magnetic power module 10 to be inserted into the first groove or the second groove, the third photoelectric sensor 203 on the movable end of the second drive component 202 is driven by the movable end to move to a position that can be sensed by the fourth photoelectric sensor. Based on this, when the fourth photoelectric sensor 204 senses the third photoelectric sensor 203, it can be determined that the first positioning member 101 and the first magnetic member have been connected.

[0129] In some embodiments, the third photosensor 203 may be a light signal transmitter, and the fourth photosensor 204 may be a light signal receiver.

[0130] In other embodiments, the fourth photoelectric sensor 204 may be a slot-type photoelectric sensor, and the third photoelectric sensor 203 may be a sensing piece that cooperates with the slot-type photoelectric sensor installed on the second support plate 201. Based on this, when the movable end of the second driving component 202 drives the sensing piece to move into the groove of the slot-type photoelectric sensor, the slot-type photoelectric sensor can sense the existence of the slot-type photoelectric sensing piece, and then determine that the first positioning member 101 in the magnetic power module 10 has been engaged with the first magnetic member in the pressure-maintaining device.

[0131] In some embodiments, the control device may further include a control module for controlling the states of the first drive component and the second drive component 202 included in the control device. Based on this, the control module may also determine that the first positioning member 101 and the first magnetic member have been engaged when the fourth photoelectric sensor 204 senses the third photoelectric sensor 203, and then control the movable end of the second drive component 202 to stop rising, and start the first drive component to drive the first positioning member 101 to rotate, so as to further increase the degree of automation of magnetization and demagnetization of the pressure holding device.

[0132] In some embodiments, the apparatus further comprises:

[0133] The support portion 205 is formed by the first portion of the first support plate protruding in a direction away from the second support plate 201, and at least one magnetic power module 10 is arranged on the support surface of the support portion 205;

[0134] At least two extension portions 206 are formed by extending the second portion of the first support plate in a direction parallel to the support surface;

[0135] At least two third grooves are formed by the second support plate 201 being recessed, and the extension portion 206 is engaged with the corresponding third grooves, and the notch diameter of the third groove is greater than the thickness of the extension portion 206 in the direction perpendicular to the support surface.

[0136] It can be understood that the first support plate can include a support portion 205, wherein the support portion 205 is a plane formed by the first part of the first support plate protruding in a direction away from the second support plate 201, and all the magnetic power modules 10 included in the control device are installed on the support surface of the support portion 205, wherein the support surface is the surface of the support portion 205 away from the second support plate 201. The second part of the first support plate is located below the first part and is perpendicular to the first part. The second part of the first support plate also has an extension portion 206 extending in a direction parallel to the support surface. In addition, the second support plate 201 has a third groove at one end close to the first support plate, and the extension portion 206 on the first support plate can extend into the corresponding third groove on the second support plate 201, so that the second support plate 201 is clamped with the first support plate, and the extension portion 206 on the first support plate can move in the third groove in a direction perpendicular to the support portion.

[0137] In some embodiments, reference Figure 3 The support surface of the support portion 205 may be a horizontally arranged rectangular surface. Based on this, when the control device includes multiple magnetic power modules 10, the multiple magnetic power modules 10 may be arranged on the support surface of the support portion 205 at preset intervals along the length direction of the support surface.

[0138] For example, reference Figure 1 and Figure 3 , when the first part of the first support plate and the second part of the first support plate are split structures, the first support plate may include a flat plate arranged in a horizontal direction and a side plate arranged below the flat plate. Among them, the flat plate is the first part of the first support plate, and the side plate is the second part of the first support plate. The side plate can be arranged below the flat plate and perpendicular to the flat plate. When the flat plate is a rectangular plate, the side plate can be arranged directly below the two ends of the flat plate along the length direction of the flat plate, and is used to support the flat plate and at least one magnetic power module 10 fixedly arranged on the flat plate. In addition, when the side plate is arranged below the flat plate along the length direction of the flat plate, the side plate also has an extension portion 206 extending to both sides along the width direction of the flat plate. The second support plate 201 is provided with a third groove whose opening is parallel to the length direction of the flat plate, and the extension portion 206 on the side plate can extend into the corresponding third groove on the second support plate 201 to achieve the clamping of the first support plate and the second support plate 201.

[0139] In some embodiments, the third groove on the second support plate 201 may also be a through hole having an inner diameter greater than an outer diameter of the extension portion 206 .

[0140] In the embodiment of the present disclosure, a third groove is provided on the second support plate 201, and an extension portion 206 is provided on the second portion of the first support plate. The first support plate is clamped in the third groove of the second support plate 201 through the extension portion 206. When the first support plate moves relative to the second support plate 201 in a direction perpendicular to the support portion 205, the third groove can limit the movement range of the first support plate, thereby reducing the impact of the first positioning member 101 on the pressure maintaining device when it is inserted into the first groove or the second groove due to the excessive movement range of the first support plate.

[0141] In some embodiments, the apparatus further comprises:

[0142] The first mounting hole 207 is located on the support surface, and the magnetic power module 10 is mounted on the support portion 205 through the corresponding first mounting hole 207;

[0143] A magnetic power module 10 is fixedly disposed in a first mounting hole 207 , and a first positioning member 101 in the magnetic power module 10 protrudes from a supporting surface of the supporting portion 205 .

[0144] It can be understood that the support surface of the first support plate can also be provided with first mounting holes 207 equal in number to the number of the magnetic power modules 10, and one magnetic power module 10 is fixedly mounted in a corresponding first mounting hole 207 on the support portion 205. When the magnetic power module 10 is mounted in the corresponding first mounting hole 207, the first positioning member 101 protrudes from the support surface of the support portion 205.

[0145] In some embodiments, when the first positioning member 101 is connected to the first driving assembly via the connecting shaft 102 , the first positioning member 101 and at least a portion of the connecting shaft 102 protrude from the supporting surface of the supporting portion 205 .

[0146] In some embodiments, when the magnetic power module includes a motor 103 and a speed reducer 104, the speed reducer included in the magnetic power module 10 can be fixed in the first mounting hole 207 on the support surface, so that the magnetic power module 10 is fixed as a whole in the first mounting hole 207 of the support plate.

[0147] In some embodiments, when there are multiple first mounting holes 207 on the support portion 205, the distance between two adjacent first mounting holes 207 can be determined according to the distance between two adjacent groups of magnetic members on the pressure maintaining device.

[0148] In some embodiments, reference Figure 3 When the support portion 205 has a plurality of first mounting holes 207 , the plurality of first mounting holes 207 may be arranged on the support portion 205 at preset intervals along the length direction of the support portion 205 .

[0149] In some embodiments, the apparatus further comprises:

[0150] A third support plate 208, connecting the extensions 206 on the same side;

[0151] The second driving assembly 202 is connected to the first supporting plate via the third supporting plate 208 .

[0152] It can be understood that the control transposition can also include at least two third support plates 208, wherein one third support plate 208 is used to connect each extension 206 located on the same side. Based on this, when the second drive assembly 202 is fixed to the second support plate 201 through the fixed end, the movable end of the second drive assembly 202 can be connected to the first support plate through the third support plate 208. Based on this, when the movable end of the second drive assembly 202 moves in a direction parallel to the second support plate 201 relative to the fixed end, the third support plate 208 can be driven to move in a direction parallel to the second support plate 201, and then the first support plate can be driven to move in a direction parallel to the second support plate 201, so that the magnetic power module arranged on the first support plate is close to the pressure holding device or away from the pressure holding device.

[0153] In some embodiments, reference Figure 1 and Figure 3 The extension portion 206 located on the second part of the first support plate can pass through the third groove along the thickness direction of the second support plate 201 and extend outside the third groove. The third connecting plate can connect the ends of each extension portion 206 extending out of the third groove.

[0154] In some embodiments, the third support plate 208 includes a first surface and a second surface disposed opposite to each other, and the third support plate 208 can be disposed below the extension portion 206 and disposed horizontally. Based on this, the third support plate 208 can be fixedly connected to the portion of the extension portion 206 extending out of the third groove through the first surface, and connected to the movable end of the second driving assembly 202 through the second surface.

[0155] In some embodiments, the apparatus further comprises:

[0156] The second positioning member 209 is disposed on the first supporting plate and has the same orientation as the first positioning member 101;

[0157] When the second positioning member 209 is inserted into the fourth groove on the pressure-maintaining device, the first driving assembly drives the first positioning member 101 to rotate until the first limiting block 1012 is aligned with the alignment portion.

[0158] It is understandable that a second positioning member 209 may also be provided on the first support plate, and a fourth groove is provided on the pressure-maintaining device to cooperate with the second positioning member to fix the relative position of the magnetic power module 10 and the pressure-maintaining device. Based on this, when it is necessary to magnetize or demagnetize the pressure-maintaining device through the control device provided in the embodiment of the present disclosure, the magnetic power module 10 can be driven close to the pressure-maintaining device through the driving module 20, and the second positioning member 209 can be inserted into the corresponding fourth groove on the pressure-maintaining device so that the body 1011 of the first positioning member 101 is aligned with the body of the first groove or the second groove. Afterwards, the first driving component can drive the first positioning component to rotate until the first limit block is aligned with the alignment portion in the first groove or the alignment portion in the second groove, and the magnetic power module 10 is driven by the driving module 20 to move further in the direction close to the pressure-maintaining device, so that the first positioning component is inserted into the first groove or the second groove, and the first positioning component is connected with the first magnetic component.

[0159] In some embodiments, the first positioning member 101 can be disposed on the support portion 205 of the first support plate and located close to the first positioning member 101. Based on this, when the second positioning member 209 is inserted into the corresponding fourth groove, the accuracy of the alignment between the first positioning member 101 and the first groove or the second groove can be increased. That is, the central axis of the body 1011 of the first positioning member 101 is made to coincide with the central axis of the first groove or the second groove as much as possible.

[0160] In some embodiments, the number of the second positioning members 209 disposed on the first support plate can be set as needed, which is not limited in the embodiments of the present disclosure.

[0161] Exemplarily, the same number of second positioning members 209 as the first positioning members 101 may be arranged on the first support plate, and each second positioning member 209 is arranged at a position close to the corresponding first positioning member 101 .

[0162] In some embodiments, reference Figure 1 When two magnetic power modules 10 are arranged on the support portion 205, a second positioning member 209 may be arranged near the first positioning member 101 of each magnetic power module 10. The second positioning member 209 may be Figure 4 As shown, the approximately cylindrical positioning pin, wherein the length of the second positioning member 209 protruding from the support surface is greater than the length of the magnetic power module 10 protruding from the support surface. Based on this, when the first support plate moves toward the direction close to the pressure holding device, the end of the second positioning assembly contacts the pressure holding device before the end of the first positioning member 101.

[0163] In some embodiments, when there are multiple second positioning members 209, the shapes of the positioning portions 2091 of different positioning members may be different. Based on this, when multiple second positioning members 209 are inserted into corresponding fourth grooves, the relative movement range of the control device and the pressure maintaining device can be reduced.

[0164] For example, when there are multiple second positioning members 209, the positioning portions 2091 of some second positioning members 209 may be arc-shaped surfaces, and the positioning portions 2091 of some second positioning members 209 may be diamond-shaped surfaces. Figure 5 As shown in part A of FIG. 1 , the positioning portion 2091 of the second positioning member 209 may be as shown in FIG. Figure 5 As shown in part B.

[0165] In some embodiments, a second limit block 212 may be further provided on the first support member to limit the rotation angle of the first positioning member 101 when the first positioning member 101 rotates along the first direction or the second direction, so that the rotation angle of the first positioning member 101 is within a preset angle.

[0166] For example, reference Figure 1 and Figure 3 The second limiting block 212 can be set on the supporting portion 205 and located between the first positioning member 101 and the second positioning member 209 .

[0167] In the disclosed embodiment, a second positioning member 209 is provided on the support portion 205 near each magnetic power module. When the pressure-maintaining device needs to be magnetized or demagnetized, the relative positions of the control device and the pressure-maintaining device can be fixed by the second positioning member 209 so that the first positioning member 101 is aligned with the corresponding first groove or second groove. Afterwards, the first positioning member 101 is driven to be inserted into the first groove or the second groove by the first driving component 202, which can reduce the possibility that the first positioning member 101 is driven to move in the direction close to the pressure-maintaining device when the first positioning member 101 is not aligned with the first groove or the second groove, causing the first positioning member 101 to collide with the pressure-maintaining device.

[0168] In some embodiments, reference Figure 5 , the device further comprises:

[0169] A first photoelectric sensor 210 is disposed on the first limit block 1012;

[0170] The second photoelectric sensor 211 is disposed on the first support plate, and is used for performing photoelectric sensing with the first photoelectric sensor 210 after the first limiting block 1012 drives the first photoelectric sensor 210 to rotate along the first direction by a preset angle.

[0171] It can be understood that a first photoelectric sensor 210 can also be provided on the first limit block 1012, and a second photoelectric sensor 211 capable of photoelectrically sensing the first photoelectric sensor 210 is provided at a preset position of the first support plate. When the first driving component drives the first positioning member 101 to rotate by a preset angle along the first direction or the second direction, the first limit block 1012 on the first positioning member 101 can drive the first photoelectric sensor to rotate to a position for photoelectrically sensing the second photoelectric sensor 211. Based on this, when the control device also includes a control module, the second photoelectric sensor 211 can send a signal to the control module when sensing the first photoelectric sensor 210, so that the control module knows that the first positioning member 101 has driven the first magnetic member to complete the magnetization or demagnetization of the pressure-maintaining device.

[0172] In some embodiments, the first photosensor 210 may be an optical signal transmitter, and the second photosensor 211 may be an optical signal receiver cooperating with the optical signal transmitter.

[0173] Exemplarily, the second photoelectric sensor 211 is a slot-type photoelectric sensor, and the first photoelectric sensor 210 is a sensing piece used in conjunction with the slot-type photoelectric sensor disposed on the support portion 205. After the first positioning member 101 rotates by a preset angle along the first direction or the second direction, the sensing piece on the first limit block 1012 can just be inserted into the groove of the slot-type photoelectric sensor. When the slot-type photoelectric sensor determines that the sensing piece is inserted into the groove, a signal can be sent to the control module to let the control module know that the first positioning member 101 has driven the first magnetic member to complete the magnetization or demagnetization action of the pressure-maintaining device.

[0174] It should be noted that the connection between the various components included in the above-mentioned control device can be a direct connection or an indirect connection, and the embodiments of the present disclosure are not limited to this.

[0175] In addition, the fixing method of the fixed connection between the above-mentioned components can be any feasible fixing method, such as screw fixing, bolt fixing, adhesive fixing, plug fixing, etc., which is not limited in the embodiments of the present disclosure.

[0176] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein.
