Description
Technical Field
[0001] This application relates to the field of workpiece machining and positioning, and in particular to a magnetic positioning device. Background Technology
[0002] Before processing a workpiece using processing equipment, the workpiece needs to be positioned on a positioning fixture set in the preset area of the processing equipment.
[0003] A positioning fixture in the prior art includes a positioning base fixed in a preset area of a processing equipment. The top wall of the positioning base has a positioning groove for embedding a workpiece. Several positioning rods are also fixed on the top wall of the positioning base. The positioning rods are used to fit into corresponding positioning holes on the workpiece. In practice, the workpiece is fitted onto the positioning rods through the positioning holes on the workpiece, and the workpiece is also embedded in the positioning groove. This makes it easy to position the workpiece on the positioning fixture, thereby positioning the workpiece in a preset position on the processing equipment, so that the processing equipment can process it subsequently.
[0004] In the process of developing this application, it was found that the above-mentioned technology has at least the following problems: Current processing equipment has a wide range of functions and can process not only a single type of workpiece; each type of workpiece has a different structure or shape and requires a specific positioning fixture to position it in the preset position of the processing equipment. Therefore, each time a different type of workpiece needs to be changed, the original positioning fixture needs to be removed from the processing equipment and replaced with a positioning fixture corresponding to the existing type of workpiece; it can be seen that the universality of the existing positioning fixture is poor. Summary of the Invention
[0005] To improve the versatility of positioning fixtures, this application provides a magnetic positioning device.
[0006] The magnetic positioning device provided in this application adopts the following technical solution:
[0007] A magnetic positioning device includes an electric magnetic platform, a support sensor above the electric magnetic platform, and a processor communicatively connected to the support sensor and the electric magnetic platform. The electric magnetic platform is provided with a support for positioning a workpiece and an abutment positioning structure for abutting and positioning the support, and the abutment positioning structure is electrically connected to the processor.
[0008] By adopting the above technical solution, the electric magnetic platform is positioned at a preset position on the processing equipment. Then, a support is placed on the top wall of the electric magnetic platform. Before the support is placed on the electric magnetic platform and is close to its preset position, the support's sensor detects it and sends a corresponding electrical signal to the processor. The processor then controls the electric magnetic platform to begin magnetically attracting the support based on this signal. This facilitates the initial positioning of the support on the electric magnetic platform using magnetic attraction. Furthermore, the processor controls the abutment positioning structure to support the support magnetically attracted on the electric magnetic platform. The workpiece is positioned by abutment. When a different type of workpiece needs to be processed, the processor first controls the abutment positioning structure to reset, and at the same time controls the electric magnetic suction platform to lose its magnetism. Then, the other type of workpiece is first positioned on the corresponding support, and then the support is placed on the electric magnetic suction platform, where it is positioned by magnetic attraction and abutment. In this way, when positioning different types of workpieces, it is not necessary to remove the entire positioning fixture. Instead, the other corresponding support can be repositioned by magnetic attraction and abutment. Compared with the existing technology, this improves the universality of the positioning fixture.
[0009] In one specific implementation, the electric magnetic platform is provided with a placement slot; the support sensor includes a first proximity sensor disposed in the placement slot, the first proximity sensor being communicatively connected to the processor.
[0010] By adopting the above technical solution, the placement slot prevents the first proximity sensor placed therein from protruding from the outer wall of the electric magnetic platform, thus facilitating the placement of the support on the electric magnetic platform. After the support is moved to a certain position close to the electric magnetic platform, the first proximity sensor can sense the support and generate a corresponding electrical signal, which is then sent to the processor. The processor controls the electric magnetic platform to generate magnetism to magnetically attract the support based on the corresponding electrical signal. This allows the electric magnetic platform to be powered on and generate magnetism only when it needs to magnetically attract the support. When the support is not close to the electric magnetic platform, the electric magnetic platform is powered off and loses its magnetism, thus improving the intelligence of the electric magnetic platform and saving energy.
[0011] In one specific implementation, the abutment positioning structure includes a first pressure sensor connected to the bottom of the electric magnetic platform, the first pressure sensor being communicatively connected to the processor.
[0012] By adopting the above technical solution, after the support is placed on the electric magnetic platform, the first pressure sensor between the electric magnetic platform and the processing equipment will detect a larger pressure signal and transmit the pressure signal to the processor. The processor will analyze and judge the pressure signal. If it is determined that the pressure is greater than the original pressure, it will determine that the support has been placed on the electric magnetic platform. Then, the processor will control the abutment positioning component to abut and position the support placed on the electric magnetic platform. This allows for immediate control of the abutment positioning result to abut and position the support as soon as it is detected that it has been placed on the electric magnetic platform, thereby improving the intelligence level and efficiency of the abutment positioning support.
[0013] In one specific implementation, the abutment positioning structure includes an end abutment positioning component and a side abutment positioning component connected to the electric magnetic suction platform; the end abutment positioning component is used to abut the end of the support to position the support, and the side abutment positioning component is used to abut the side of the support to position the support.
[0014] By adopting the above technical solution, after the support is positioned vertically by the electric magnetic suction platform, the two ends of the support are positioned horizontally by the end abutment positioning component, and the two sides of the support are positioned horizontally by the side abutment positioning component; thus, the six degrees of freedom of the support can be restricted to improve the positioning effect of the support.
[0015] In one specific implementation, the end abutment positioning component includes a first electric telescopic member connected to the end of the electric magnetic suction platform, the first electric telescopic member being electrically connected to the processor; a first base plate is provided on the first electric telescopic member, a first connecting bolt is slidably connected to the first base plate, a first abutment plate is connected to the first connecting bolt, a first reset spring is connected between the first base plate and the first abutment plate, and a second proximity sensor is connected to the first base plate.
[0016] By adopting the above technical solution, when the two ends of the support are positioned by abutment, the processor controls the two first electric telescopic rods to extend towards the corresponding end of the support. When the corresponding first abutment plate abuts against the corresponding end of the support, the first return spring is compressed. The first return spring is designed to prevent the first abutment plate from rigidly abutting against the support, thus preventing mutual damage. When the first abutment plate initially abuts against the support, the corresponding first electric telescopic member will continue to extend. At this time, the first return spring is gradually compressed, and the first abutment plate gradually approaches the first substrate. During this process, the second proximity sensor will sense the first substrate and send a corresponding electrical signal to the processor when it senses the first substrate. This allows the processor to control the corresponding first electric telescopic member to stop extending based on the electrical signal. This helps to prevent the first electric telescopic rod from over-extending after the end of the support is positioned by abutment.
[0017] In one specific implementation scheme, the electric magnetic suction platform has an installation cavity, a drive component is provided in the installation cavity, a drive gear is connected to the drive component, two racks are slidably connected to the electric magnetic suction platform, the two racks are parallel and both mesh with the drive gear, a second base plate is connected to the racks, a second pressure sensor is connected to the second base plate, and the second pressure sensor is connected to a second abutment plate.
[0018] By adopting the above technical solution, when the support needs to be positioned by side contact, the processor starts the drive component, which drives the drive gear to rotate. The drive gear synchronously drives the two racks to move, so that the two second contact plates move closer to each other and abut against the support. During this process, the second pressure sensor transmits the measured pressure data to the processor. The processor judges the received pressure data. When it is determined that the pressure data has reached the preset pressure threshold, the processor immediately controls the drive component to stop rotating, so that the two second contact plates no longer move closer to each other. This makes it easy to control the drive component to stop operating after the side contact positioning of the support is achieved.
[0019] In one specific implementation, a mounting plate is included for mounting above the support, the mounting plate having a camera communicatively connected to the processor and an alarm component electrically connected to the processor.
[0020] By adopting the above technical solution, a camera is used to capture images of the top wall of the support, and then the captured images are sent to a processor. The processor determines whether the top wall of the support is level by processing the images. If not, it controls the alarm component to send corresponding alarm information to the staff so that the staff can deal with the abnormal situation in a timely manner.
[0021] In one specific implementation, the support includes a base body with at least three limiting rods connected to it; the mounting plate is provided with translation components corresponding to the limiting rods one by one, the translation components are electrically connected to the processor, the translation components are provided with a second electric telescopic component electrically connected to the processor, the second electric telescopic component is connected with an end component for contacting the corresponding limiting rod, and the end component is electrically connected to the processor.
[0022] By adopting the above technical solution, an image of the top wall of the support is captured by a camera and then sent to a processor for image processing to determine the horizontal position of each limit rod. Based on the horizontal position of each limit rod, the processor controls the translation component to move the second electric telescopic rod until the end component is aligned vertically with the limit rod. The processor then controls the second electric telescopic rod to extend towards the top of the corresponding limit rod until the end component contacts the corresponding limit rod. The processor then determines whether different end components simultaneously contact the corresponding limit rod. If not, the processor determines that the top wall of the support is not horizontal and controls the alarm component to send an alarm message to the staff, allowing them to handle the abnormal situation promptly.
[0023] In one specific implementation, the end assembly includes a third base plate connected to the second electric telescopic member, a second connecting bolt slidably connected to the third base plate, a power supply board connected to the second connecting bolt, a second reset spring connected between the power supply board and the third base plate, the power supply board being electrically connected to the processor, and a first end and a second end connected to the power supply board.
[0024] By adopting the above technical solution, when the first end and the second end contact the corresponding limit rod, the circuit board is energized and then sends a corresponding electrical signal to the processor. The processor determines whether several electrical signals are sent at the same time. If not, the processor determines that the top wall of the support is not in a horizontal state and then controls the alarm component to send an alarm message to the staff so that the staff can deal with the abnormal situation in a timely manner.
[0025] In one specific feasible implementation, the electric magnetic platform is provided with several anti-slip grooves.
[0026] By adopting the above technical solution, the anti-slip grooves help prevent the support from sliding relative to the electric magnetic platform during the positioning process, thereby improving the stability of the support positioning.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. Compared with existing technologies, it can improve the universality of positioning fixtures;
[0029] 2. Facilitates improvements in the intelligence of the electric magnetic platform to save energy;
[0030] 3. Facilitates improved stability of the support positioning. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0041] This application discloses a magnetic positioning device. (Refer to...) Figure 1 and Figure 2 The magnetic positioning device includes an electric magnetic platform 2 for limiting the position on the processing equipment 1. A support sensor 3 is provided above the electric magnetic platform 2. The support sensor 3 is communicatively connected to a processor 4. The processor 4 is also electrically connected to the electric magnetic platform 2. A support 5 for positioning the workpiece is provided on the top wall of the electric magnetic platform 2. The electric magnetic platform 2 is used to magnetically position the support 5 in the vertical direction. An abutment positioning structure 6 is also provided on the electric magnetic platform 2. The abutment positioning structure 6 is used to abut and position the support 5 in the horizontal direction. The magnetic positioning device also includes a horizontal detection structure 7 set on the processing equipment 1 and located above the support. The horizontal detection structure 7 is used to detect whether the top wall of the support 5 is in a horizontal state.
[0042] It should be noted that when it is necessary to change to another type of workpiece to be processed, the processor 4 first controls the abutment positioning structure 6 to reset, and at the same time controls the electric magnetic suction platform 2 to lose its magnetism. Then, the other type of workpiece is first positioned on the corresponding support 5, and then the support 5 is placed on the electric magnetic suction platform 2, and the support 5 is positioned by magnetic attraction and abutment positioning. In this way, when positioning different types of workpieces, it is not necessary to remove the entire positioning fixture, but to re-magnetically attract and abut against the other corresponding support 5. Compared with the existing technology, the universality of the positioning fixture can be improved.
[0043] Reference Figure 2 The electric magnetic platform 2 is square in shape. Positioning holes 21 are provided vertically at the four corners of the electric magnetic platform 2. The positioning holes 21 are used for the positioning rods preset on the processing equipment 1 to be inserted, thereby achieving the purpose of positioning the electric magnetic platform 2 at the preset position of the processing equipment 1.
[0044] To prevent the support 5 placed on the electric magnetic platform 2 from sliding relative to the electric magnetic platform 2, several anti-slip grooves 22 are evenly provided on the top wall of the magnetic platform, which helps to improve the stability when the support 5 is positioned on the electric magnetic platform 2.
[0045] The top wall of the electric magnetic platform 2 has a placement slot 23 at its center, as shown in the reference. Figure 3 The support seat sensing element 3 is a first proximity sensor 31 disposed in the placement slot 23 and connected to the electric magnetic suction platform 2. The first proximity sensor 31 is electrically connected to the processor 4.
[0046] In practice, the support 5 is not always placed on the electric magnetic platform 2. If the electric magnetic platform 2 is kept in an electromagnetic attraction state even when the support 5 is not placed on the electric magnetic platform 2, it will result in a waste of electrical energy.
[0047] In the implementation of this technical solution, when the support 5 is moved to a position close to the top wall of the electric magnetic platform 2, the first proximity sensor 31 can sense the support 5 and send a first electrical signal to the processor 4. Then, the processor 4 controls the electric magnetic platform 2 to be in an electromagnetic attraction state based on the first electrical signal, thereby magnetically attracting the support 5 that has been placed on the top wall of the electric magnetic platform 2. This facilitates the magnetic positioning of the support 5 in the vertical direction. When the support 5 is removed from the electric magnetic platform 2 until the support 5 is out of the sensing range of the first proximity sensor 31, the processor 4 will no longer receive the first electrical signal and will immediately control the electric magnetic platform 2 to be in a power-off state. This facilitates the improvement of the energy efficiency and intelligence level of the electric magnetic platform 2.
[0048] Reference Figure 3 The abutment positioning structure 6 includes a first pressure sensor 61 mounted on the processing equipment 1. The first pressure sensor 61 is used to abut against the bottom wall of the electric magnetic suction platform 2, in conjunction with... Figure 1 The first pressure sensor 61 is connected to the processor 4.
[0049] The abutment positioning structure 6 also includes two end abutment positioning components 62 disposed on the electric magnetic platform 2. Both end abutment positioning components 62 are electrically connected to the processor 4. The two end abutment positioning components 62 correspond one-to-one with the two ends of the electric magnetic platform 2. Each end positioning component is disposed at the corresponding end of the electric magnetic platform 2. The two end abutment positioning components 62 are used to abut together against the end of the support seat 5 magnetically attached to the electric magnetic platform 2, thereby realizing the end abutment positioning of the support seat 5.
[0050] The abutment positioning structure 6 also includes a side abutment positioning component 63 disposed in the middle of the electric magnetic platform 2. The side abutment positioning component 63 is electrically connected to the processor 4. The side abutment positioning component 63 is used to synchronously abut against the side of the support seat 5 magnetically attached to the electric magnetic platform 2, thereby realizing the side abutment positioning of the support seat 5.
[0051] In practice, after the support 5 is placed on the electric magnetic platform 2, the first pressure sensor 61 transmits the corresponding pressure signal to the processor 4. At this time, the processor 4 determines that the pressure corresponding to the pressure signal is greater than the pressure when the support 5 is not placed on the electric magnetic platform 2. At this time, the processor 4 determines that the support 5 has been placed on the electric magnetic platform 2. Then, the processor 4 simultaneously controls the end abutment positioning component 62 and the side abutment positioning component 63 to abut and position the support 5 magnetically attached to the electric magnetic platform 2.
[0052] Reference Figure 3 The two end-abutment positioning components 62 have identical structures and are symmetrically arranged. Here, we will only describe one of the end-abutment positioning components 62. (Refer to...) Figure 4The end abutment positioning component 62 includes a folded seat 621 connected to the end side wall of the electric magnetic suction platform 2. A first electric telescopic member 622 electrically connected to the processor 4 is fixed on the folded seat 621. In this embodiment, the first electric telescopic member 622 is preferably an electric cylinder. Both first electric telescopic members 622 are arranged in the horizontal direction and are coaxial. In addition, the extension directions of the two first electric telescopic members 622 are arranged facing each other. A first base plate 623 is fixed to the end of the first electric telescopic member 622 near the end of another first electric telescopic member 622. A plurality of first connecting bolts 624 are slidably connected to the first base plate 623. The axial direction of the first connecting bolts 624 is parallel to the axial direction of the first electric telescopic member 622. A first abutting plate 625 is fixedly connected to the end of the plurality of first connecting bolts 624 away from the first base plate 623. The first abutting plate 625 is used to abut against the end side wall of the corresponding support seat 5. A first return spring 626 is sleeved on each first connecting bolt 624 and connected between the first base plate 623 and the first abutting plate 625. A second proximity sensor 627 is fixed on the side wall of the first base plate 623 near the first abutting plate 625. The second proximity sensor 627 is used to sense the corresponding first abutting plate 625.
[0053] In practice, after the support 5 is placed on the electric magnetic platform 2 and magnetically positioned, the first pressure sensor 61 transmits the corresponding pressure signal to the processor 4. The processor 4 controls the two first electric telescopic members 622 to extend towards the corresponding end sidewall of the support 5 based on the pressure signal. When the first abutting plate 625 abuts against the support 5, the first electric telescopic member 622 continues to extend until the first abutting plate 625 enters the sensing range of the corresponding second proximity sensor 627. During this process, the first return spring 626 is gradually compressed, and the elastic reaction force generated by compressing the first return spring 626... The first abutting plate 625 is gradually pressed against the support seat 5. When the second proximity sensor 627 senses the first abutting plate 625, it immediately sends a second electrical signal to the processor 4. After receiving the second electrical signal, the processor 4 determines that the two ends of the support seat 5 are in a pressed state. Then, the processor immediately controls the two first electric telescopic members 622 to stop extending to prevent the first electric telescopic members 622 from over-extending. This facilitates timely control of the electric telescopic members to stop extending after the ends of the support seat 5 are pressed against the support. In this way, the end abutting positioning of the support seat 5 is achieved, and the level of intelligence of the end abutting positioning is also improved.
[0054] Looking back Figure 2 An installation cavity 24 is provided through the middle of the electric magnetic suction platform 2, and the length of the installation cavity 24 is set along the width of the electric magnetic suction platform 2; refer to Figure 5The side-mounted positioning component 63 includes a drive member 631 fixed to the center of the bottom wall of the mounting cavity 24. The drive member 631 is electrically connected to the processor 4. In this embodiment, the drive member 631 is preferably a motor. The output shaft of the drive member 631 is vertically upward, and a drive gear 632 is coaxially fixed to the top of the output shaft of the drive member 631. The mounting cavity 24 is also provided with two racks 633 that are slidably connected to the electric magnetic platform 2. The length direction of the two racks 633 is parallel to the length direction of the mounting cavity 24. The two racks 633 are arranged horizontally on both sides of the drive gear 632 and mesh with the drive gear 632. Each rack 633 can extend out of the mounting cavity. A connector 634 is fixed to one end of each cavity 24. The top of the connector 634 is higher than the top wall of the electric magnetic platform 2. A second base plate 635 is fixed to the top of each connector 634. The length direction of the second base plate 635 is parallel to the length direction of the electric magnetic platform 2. A second pressure sensor 636 is fixed to the side wall of the second base plate 635 near the support 5. The second pressure sensor 636 is electrically connected to the processor 4. A second abutment plate 637 is fixed to the side wall of the second pressure sensor 636 near the support 5. The two second abutment plates 637 correspond one-to-one with the two side walls of the support 5. In this embodiment, the second abutment plate 637 is preferably a rubber plate.
[0055] In implementation, while controlling the two end-abutment components to perform end-abutment positioning of the support seat 5 magnetically positioned on the electric magnetic platform 2, the processor 4 also controls the side-abutment positioning component 63 to perform abutment positioning of the support seat 5. Specifically, while controlling the extension of the two first electric telescopic rods, the processor 4 also controls the drive component 631 to drive its output shaft, thereby causing the drive gear 632 to drive the two racks 633 to move towards each other, thereby causing the two second abutment plates 637 to abut against the two corresponding side walls of the support seat 5 to achieve side-abutment positioning of the support seat 5. The second abutment plate 637 is preferably a rubber plate, which can play a buffering role by utilizing its deformable characteristics during the process of the second abutment plate 637 abutting against the support seat 5; when the second abutment plate 637 abuts against the corresponding side of the support seat 5, the corresponding second pressure sensor 636 can detect the corresponding pressure and transmit the pressure data to the processor 4. When the processor 4 determines that the pressure value corresponding to the pressure data reaches the preset pressure threshold, it immediately controls the drive component 631 to stop rotating. Thus, while realizing the side abutment positioning of the support seat 5, it can also realize the timely stopping of the drive component 631, thereby improving the intelligence level of the side abutment positioning component 63 abutting and positioning support seat 5.
[0056] It should be noted that the anti-slip groove 22 can work with the end abutment positioning component 62 and the side abutment positioning component 63 to position the support seat 5.
[0057] It should be noted that, in order to ensure the accuracy of the processing, before processing the workpiece on the support 5 which is positioned by the abutment positioning structure 6, the top wall of the support 5 must be in a horizontal state.
[0058] In this embodiment, the horizontal detection structure 7 is used to detect whether the top wall of the support 5 is horizontal. (Refer to...) Figure 6 The support 5 includes a seat 51 for placement on the top wall of the electric magnetic platform 2. The seat 51 is square in shape. Limiting rods 52 are fixed at the four corners of the top wall of the seat 51. The four limiting rods 52 are all perpendicular to the top wall of the seat 51, and the top of the four limiting rods 52 are at the same height relative to the top wall of the seat 51.
[0059] In one embodiment, the horizontal detection structure 7 includes a mounting plate 71 connected to the processing equipment 1. The mounting plate 71 is arranged horizontally and positioned above the support 5. A camera 72 is fixed on the bottom wall of the mounting plate 71 and is communicatively connected to the processor 4.
[0060] In practice, after the support seat 5 is positioned by the abutting positioning structure 6, the processor 4 controls the camera 72 to take a picture of the top of the support seat 5, and then sends the picture to the processor 4. The processor 4 processes the picture to determine whether the top wall of the seat 51 is in a horizontal state.
[0061] In another embodiment, the horizontal detection structure 7 further includes four translation components 73 disposed on the bottom wall of the mounting plate 71. Each of the four translation components 73 corresponds one-to-one with one of the four limiting rods 52 in the support 5, with each translation component 73 located directly above the corresponding limiting rod 52; specifically, refer to... Figure 7 The translation component 73 includes a horizontal linear module 731 on the bottom wall of the connected mounting plate 71 and located directly above the corresponding limiting rod 52. The slider of the horizontal linear module 731 faces vertically downward, and a vertical linear module 732 is fixed to the bottom wall of the slider of the horizontal linear module 731. The vertical linear module 732 is perpendicular to the horizontal linear module 731, and the slider of the horizontal linear module 731 also faces downward.
[0062] A second electrically operated telescopic component 74, arranged vertically, is fixed to the bottom wall of the slider of the horizontal linear module 731. It should be noted that the horizontal linear module 731, the vertical linear module 732, and the second electrically operated telescopic component 74 are all electrically connected to the processor 4. Each second electrically operated telescopic component 74 has an end assembly 75 at its bottom end for contacting the top wall of the corresponding limiting rod 52. Specifically, refer to... Figure 8The end assembly 75 includes a third base plate 751 connected to the bottom end of the corresponding second electric telescopic rod. The third base plate 751 is arranged in a horizontal direction. A plurality of second connecting bolts 752 arranged in a vertical direction are slidably connected to the third base plate 751. The bottom ends of the plurality of second connecting bolts 752 are connected to a power supply board 753 electrically connected to the processor 4. Each second connecting bolt 752 is fitted with a second return spring 754 connected between the third base plate and the power supply board 753. The power supply board 753 is arranged in a horizontal direction. The bottom wall of the power supply board 753 is provided with a first end 755 and a second end 756 for contacting the top wall of the corresponding limiting rod 52. The distance between the first end 755 and the second end 756 is less than the diameter of the limiting rod 52.
[0063] In implementation, after the support seat 5 is positioned by the abutment positioning structure 6, the processor 4 controls the camera 72 to capture an image of the top wall of the support seat 5. The captured image is then processed to determine the horizontal coordinates of the four limiting rods 52. Based on each coordinate, the processor 4 controls the operation of the corresponding horizontal linear module 731 and vertical linear module 732 until the first end 755 and the second end 756 of each group are directly above the top wall of the corresponding limiting rod 52. At this point, the distance between the bottom wall of each first end 755 and the bottom wall of the corresponding limiting rod 52 is consistent. Then, the processor 4 controls the four second electric telescopic rods to move at the same speed... The lower extension; when the first end 755 and the second end 756 of each group simultaneously contact the corresponding limiting rod 52, a passage is formed between the power supply board 753, the first end 755, the second end 756 and the corresponding limiting plate. At this time, the power supply board 753 immediately sends a third electrical signal to the processor 4. In this way, the processor 4 will collect a total of 4 third electrical signals, and then determine whether the timing of collecting the 4 third electrical signals is consistent. If so, it means that the four groups of first end 755 and second end 756 simultaneously contact the corresponding limiting rod 52, that is, it means that the top wall height of the four limiting rods 52 is consistent, that is, it means that the top wall of the seat 51 is in a horizontal state; otherwise, it is determined that the top wall of the seat 51 is not in a horizontal state.
[0064] To facilitate timely communication of the assessment results regarding whether the top wall of seat 51 is level to staff, refer to Figure 6 The processor 4, which is mounted on the top wall of the mounting plate 71, is also electrically connected to an alarm component 76. Specifically, the alarm component 76 includes a first alarm 761 and a second alarm 762 connected to the top wall of the mounting plate 71, and both the first alarm 761 and the second alarm 762 are electrically connected to the processor 4.
[0065] In practice, if the processor 4 determines that the top wall of the seat 51 is in a horizontal state, the processor 4 controls the first alarm 761 to issue an alarm message; if the processor 4 determines that the top wall of the seat 51 is not in a horizontal state, the processor 4 controls the second alarm 762 to issue an alarm message; this makes it easy to promptly convey the judgment result of whether the top wall of the seat 51 is in a horizontal state to the staff.
[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
