Description

Technical Field

[0001] The utility model relates to the technical field of intelligent toilet component detection equipment, and more specifically, it relates to a device for automatically detecting the effectiveness of induction elements. Background Art

[0002] With the increasing living standards of people, the demand for the convenience and intelligence of various products is also increasing. Traditional toilets are gradually being phased out, and intelligent toilets are gradually entering every household. At the same time, the popularization of intelligent toilets is also the basis for realizing an intelligent home in the future. An important component in an intelligent toilet is the induction element. To achieve functions such as automatic toilet lid opening, automatic flushing, and automatic heating of the toilet seat ring in an intelligent toilet, the induction element needs to be used. Therefore, detecting the effectiveness of the induction element in advance during the assembly of the intelligent toilet is an important link to ensure the quality of the produced intelligent toilet.

[0003] In the prior art, when detecting the effectiveness of the induction element of an intelligent toilet, the general method is that the user aligns the shielding plate with the induction element and keeps a certain distance. If the induction element is effective, the induction element will sense the presence of the shielding plate and then transmit the induction signal to the PLC controller, and the PLC controller controls the signal lamp to light up. If the induction element is ineffective, the signal lamp does not light up, so as to judge the effectiveness of the induction element.

[0004] However, the common methods for detecting the effectiveness of intelligent toilet induction elements have the following problems:

[0005] 1. When the induction element is produced, there is a preset optimal induction distance in advance. For different types of induction elements, the originally set optimal induction distance is also different. If an employee holds the shielding plate to test the effectiveness of the induction element, it is often because the employee has poor control over the distance between the shielding plate and the induction element, resulting in the employee being unable to quickly and accurately detect the effectiveness of the induction element and needing to operate repeatedly, reducing work efficiency.

[0006] 2. The existing manual detection method cannot detect a large number of induction elements at the same time, and the work efficiency is low.

[0007] 3. During the existing manual detection, since the employee's hand is prone to shaking, the work efficiency will also be reduced during the detection. Summary of the Invention

[0008] Aiming at the existing technical problems, the purpose of the utility model is to provide a device for automatically detecting the effectiveness of induction elements, so that the device can automatically sense the type of the induction element to be detected and automatically adjust the distance between the shielding plate and the induction element, facilitating the employee to detect the effectiveness of the induction element.

[0009] To achieve the above object, the utility model provides the following technical solutions:

[0010] A device for automatically detecting the effectiveness of induction elements, comprising a detection table and a control system. The control system includes a PLC controller and an operation display screen. The operation display screen is electrically connected to the PLC controller. A linear module is arranged on the tabletop of the detection table. A cylinder is arranged at the slider of the linear module. The cylinder block of the cylinder is fixedly connected to the slider of the linear module. One end of the piston rod of the cylinder is fixedly connected with a shielding plate. The shielding plate is located outside the cylinder block of the cylinder. The PLC controller controls the operation of the linear module and the cylinder.

[0011] When the slider drives the cylinder block to move, the piston rod extends out of the cylinder block. At this time, the shielding plate is facing the placement rack. The placement rack is used for placing various tooling plates. The surface of the tooling plate facing the shielding plate is used for placing induction elements. The induction element and the shielding plate are within the induction distance.

[0012] An RFID chip is fixedly connected to the surface of the tooling plate facing the detection table. An RFID reader is fixedly connected to the tabletop of the detection table. The induction element and the RFID reader are both electrically connected to the PLC controller.

[0013] By adopting the above technical solutions, a fixed number can be manually set for the same type of induction elements. Then, the tooling plate carrying this type of induction elements is fixedly connected with an RFID chip, and the previously set fixed number is electronically stored in the RFID. The fixed number corresponding to this type of induction elements and the induction distance corresponding to this fixed number are also stored in advance in the PLC controller. After the induction element is electrically connected to the PLC controller, an induction element number representing the induction element will be generated in the PLC control and displayed on the operation display screen. When an employee is using it, the tooling plate carrying a certain type of induction elements is placed on the placement rack. At this time, the RFID reader will read the RFID chip on the tooling plate and then send the read fixed number to the PLC controller. The PLC controller matches the corresponding induction distance according to the received fixed number and issues a control command. The PLC controller controls the slider of the linear module to move linearly and controls the piston rod of the cylinder to extend and retract, so as to move the shielding plate to a position directly opposite to the tooling plate and make the shielding plate move to the corresponding induction distance. If a certain induction element is effective, it will sense the shielding plate and then send an induction signal to the PLC controller. The PLC controller then controls the operation display screen to display a valid symbol at the induction element number representing the induction element. If a certain induction element fails, the operation display screen will not display a valid symbol at the induction element number representing the induction element. In this way, it enables employees to more conveniently and accurately detect the effectiveness of induction elements.

[0014] Further, the operation display screen is a touch screen.

[0015] By adopting the above technical solution, the operation display screen is set as a touch screen, so that later it is convenient for employees to perform operations such as page turning by touching and clicking, which is convenient for users to view the effectiveness of a certain sensing element or perform editing operations.

[0016] Further, the placement rack includes a plurality of vertical plates fixedly connected to the tabletop of the detection table. The vertical plates are respectively located at both ends of the tooling plate. A U-shaped groove is fixedly connected to the surface of each vertical plate facing the tooling plate, and both ends of the tooling plate are clamped into the U-shaped groove.

[0017] By adopting the above technical solution, when a user needs to place the tooling plate on the placement rack, they can hold the tooling plate and clamp both ends of the tooling plate into the U-shaped grooves at both ends respectively. This is not only convenient for installation, but also the limiting effect of the U-shaped groove can reduce the situation that the tooling plate is accidentally knocked off by employees during the detection of the sensing element.

[0018] Further, a blocking plate is fixedly connected to one end of the U-shaped groove.

[0019] By adopting the above technical solution, the blocking plate is to reduce the situation that employees accidentally push the tooling plate out from one end of the U-shaped groove during the detection of the sensing element.

[0020] Further, a rotatable movable baffle is provided at the end of the U-shaped groove away from the blocking plate.

[0021] By adopting the above technical solution, when a user needs to place the tooling plate on the placement rack, they push aside the movable baffle and clamp the tooling plate into the U-shaped groove from the end of the U-shaped groove away from the blocking plate. After the tooling plate is installed, they rotate the movable baffle to block the end of the U-shaped groove away from the blocking plate. In this way, not only can the installation of the tooling plate be completed, but also after the tooling plate is installed, it will not be accidentally pushed out by employees during the detection of the sensing element due to carelessness.

[0022] Further, the tooling plate can place a plurality of sensing elements at the same time.

[0023] Further, two groups of tooling plates are provided.

[0024] By adopting the above technical solution, it is to increase the number of sensing elements of the same type detected simultaneously.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. Through the cooperation of the RFID chip, RFID reader, PLC controller, linear module, cylinder, and operation display screen, when the tooling plate loaded with the sensing element is placed on the placement rack by the user, the PLC controller can automatically adjust the distance between the shielding plate and the sensing element for detection without the user performing other operations. The detection result is displayed to the user through the operation display screen. This method of detecting the effectiveness of the sensing element is convenient, fast, and accurate, improving the work efficiency of employees; 2. The setting of the tooling plate can detect multiple sensing elements of the same type simultaneously. Stably installing the tooling plate on the placement rack further improves the work efficiency of employees in detecting the effectiveness of the sensing element. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0036] The present utility model uses terms such as "first", "second", or "third" to distinguish different objects, rather than to describe a specific order.

[0037] The orientation terms used in the present utility model, such as "upper", "lower", "left", "right", etc., are based on the orientation and positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as limiting the specific protection scope of the present utility model.

[0038] The term "fixed connection" used in the present utility model should be understood in a broad sense, that is, in the process of use, any connection method in which there is no displacement and relative rotation between the two.

[0039] See Figure 1 、 Figure 2 As shown, a device for automatically detecting the effectiveness of an induction element includes a detection table 1 and a control system. The control system includes a PLC controller 2 and an operation display screen 3. The operation display screen 3 is electrically connected to the PLC controller 2, so that the information received by the PLC controller 2 can be displayed on the operation display screen 3. In addition, for the convenience of user operation, the operation display screen 3 can also be set as a touch screen.

[0040] See Figure 1 、 Figure 3 、 Figure 4 As shown, a linear module 4 is provided on the tabletop of the detection table 1. The linear module 4 is a conventional existing structure that can make the slider 41 move linearly. Specifically, it includes a linear guide rail 42 fixedly connected to the tabletop of the detection table 1. The linear guide rail 42 is perpendicular to the tabletop of the detection table 1. A slider 41 is sleeved on the linear guide rail 42. A thread is provided between the sleeved slider 41 and the linear guide rail 42. Then, a motor 43 is used to drive the linear guide rail 42 to rotate. When the linear guide rail 42 rotates, the slider 41 will move linearly along the linear guide rail 42 on the premise that it is restricted by a restricting member 44 and cannot rotate. For the convenience of the PLC controller 2 to control the operation of the linear module 4, generally, the motor 43 that drives the linear guide rail 42 to rotate is electrically connected to the PLC controller 2.

[0041] See Figure 1 、 Figure 3 、 Figure 4As shown in the figure, in order to enable the baffle 6 used to detect the effectiveness of the induction element 9 to move in multiple dimensions, we set a cylinder 5 at the slider 41 of the linear module 4. The cylinder 5 is horizontally placed and perpendicular to the linear guide 42. The cylinder block 51 of the cylinder 5 is fixedly connected to the slider 41 of the linear module 4, and one end of the piston rod 52 of the cylinder 5 is fixedly connected to a horizontally placed baffle 6, and the baffle 6 is located outside the cylinder block 51 of the cylinder 5.

[0042] The above-mentioned cylinder 5 itself belongs to an existing conventional structure. Its working principle is to control the intake and exhaust inside the cylinder block 51 by opening and closing the solenoid valve of the cylinder 5, and then control whether the piston rod 52 extends from the cylinder block 51 or retracts into the cylinder block 51. Therefore, in order to facilitate the PLC controller 2 to control the operation of the cylinder 5, generally, the solenoid valve that controls the intake and exhaust inside the cylinder block 51 is electrically connected to the PLC controller 2.

[0043] See Figure 1 、 Figure 5 、 Figure 6 As shown in the figure, a placement rack 7 is fixedly connected to the tabletop of the inspection table 1. Various tooling plates 8 are placed on the placement rack 7. A number of induction elements 9 of the same type are placed on the side of the tooling plate 8 facing the baffle 6 at the same time. And the tooling plate 8 can be set into two groups. An RFID chip 10 is fixedly connected to the side of the tooling plate 8 facing the inspection table 1. An RFID reader 11 is fixedly connected to the tabletop of the inspection table 1. The induction element 9 and the RFID reader 11 are both electrically connected to the PLC controller 2.

[0044] Since the PLC controller 2 is originally electrically connected to the operation display screen 3, and at this time the induction element 9 is also electrically connected to the PLC controller 2, the PLC controller 2 can be used to control the operation display screen 3 to generate and display the induction element number representing the induction element 9.

[0045] Before use, a fixed number is artificially set for the same type of induction element 9, and then the RFID chip 10 on the tooling plate 8 carrying this type of induction element 9 is set, and the previously artificially set fixed number is electronically stored in the RFID chip 10. At the same time, the fixed number corresponding to this type of induction element 9 and the induction distance corresponding to this fixed number are also stored in advance in the PLC controller 2.

[0046] In use, the employee places the tooling plate 8 carrying a certain type of sensing element 9 on the placement rack 7. At this time, the RFID chip 10 reads the information of the sensing element 9 and sends it to the RFID reader 11, and the RFID reader 11 interprets the RFID chip 10 on the tooling plate 8 and then sends the interpreted fixed number to the PLC controller 2. The PLC controller 2 matches the corresponding sensing distance according to the received fixed number and issues a control command. The PLC controller 2 controls the linear module 4 to operate, so that the slider 41 moves linearly along the linear guide 42. The movement of the slider 41 drives the cylinder block 51 to move. Then the PLC controller 2 controls the cylinder 5 to operate, so that the piston rod 52 extends from the cylinder block 51. This not only makes the shielding plate 6 fixedly connected to the piston rod 52 just face the placement rack 7 exactly, but also makes the sensing element 9 on the placement rack 7 and the shielding plate 6 just within the sensing distance. At this time, if a certain sensing element 9 is effective, it will sense the shielding plate 6 and then transmit the sensing signal to the PLC controller 2. The PLC controller 2 then controls the operation display screen 3 to display a valid symbol at the sensing element 9 number representing the sensing element 9. If a certain sensing element 9 fails, the operation display screen 3 will not display a valid symbol at the sensing element 9 number representing the sensing element 9. In this way, it enables the employee to more conveniently and accurately detect the effectiveness of the sensing element 9.

[0047] See Figure 1 , Figure 7 , Figure 8 As shown, in order to enable the tooling plate 8 to be stably placed on the placement rack 7, the structure of the placement rack 7 needs to be designed. The placement rack 7 includes a plurality of vertical plates 71 fixedly connected to the tabletop of the inspection table 1. The vertical plates 71 are respectively located at both ends of the tooling plate 8. A U-shaped groove 72 is fixedly connected to the surface of the vertical plate 71 facing the tooling plate 8. A blocking plate 73 is fixedly connected to one end of the U-shaped groove 72, and a rotatable movable baffle 74 is provided at the end of the U-shaped groove 72 away from the blocking plate 73.

[0048] When placing the tooling plate 8, the user first pushes aside the movable baffle 74, inserts the tooling plate 8 from the end of the U-shaped groove 72 away from the blocking plate 73. After the two ends of the tooling plate 8 are both inserted into the U-shaped groove 72, rotate the movable baffle 74 to block the end of the U-shaped groove 72 away from the blocking plate 73.

[0049] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
