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 detecting the effectiveness of induction elements. Background Technique

[0002] In the sanitary ware field, compared with ordinary toilets, intelligent toilets are favored by household users because they are more convenient, hygienic and intelligent. The induction elements in intelligent toilets are key components that reflect the quality of intelligent toilets. The induction elements are installed on the intelligent toilet and are used to sense whether the user arrives at the intelligent toilet, whether the user gets up, etc. After the induction elements sense, they transmit the induction signals to the control system of the intelligent toilet. The control system of the intelligent toilet can control the toilet lid to open or close, control automatic flushing, etc.

[0003] During the production of intelligent toilets, in order to ensure the quality of intelligent toilets, it involves the detection of various components of intelligent toilets. When detecting the effectiveness of the induction elements of intelligent toilets, the traditional method is that employees place a shielding plate above the induction elements and keep a certain distance from the induction elements. If the induction elements sense the presence of the shielding plate, they transmit the induction signals to the control system, and the display screen in the control system will display. At this time, it is considered that the induction elements are effective. If the induction elements do not sense the presence of the shielding plate, no induction signal will be generated, and the display screen in the control system will not display either. This indicates that the induction elements are ineffective and there are quality problems.

[0004] However, this traditional method of testing the induction elements of intelligent toilets has the following problems:

[0005] 1. When the induction elements are produced, there is an optimal induction distance set. The originally set optimal induction distances of induction elements for different uses are also different. If employees use a shielding plate to test the effectiveness of the induction elements, it is often because the shielding plate held by the employees is too close or too far from the induction elements, and it is impossible to quickly and accurately detect the effectiveness of the induction elements. Not only is it very inconvenient for employees to operate, but also the efficiency of detecting the effectiveness of the induction elements is low, and the error rate is high.

[0006] 2. The effectiveness of the induction elements is displayed through the display screen of the control system, and the intuitiveness is poor, which reduces the detection operation efficiency of employees. Summary of the Invention

[0007] Aiming at the existing technical problems, the purpose of the utility model is to provide a device for detecting the effectiveness of induction elements, which uses an intelligent device to automatically adjust the distance between the shielding plate and the induction elements, facilitating employees to detect the effectiveness of the induction elements and improving the work efficiency of employees.

[0008] To achieve the above object, the present utility model provides the following technical solutions:

[0009] A device for detecting the effectiveness of an induction element, comprising a detection table and a PLC controller. The PLC controller is electrically connected to an information input device and an information display device. A linear module is provided on the detection table. The linear module includes a linear guide fixedly connected to the tabletop of the detection table. A slider is sleeved on the linear guide. A cylinder is provided at the slider. The cylinder includes a cylinder body and a piston rod. The cylinder body is fixedly connected to the slider. One end of the piston rod away from the cylinder body is fixedly connected to a shielding plate. The PLC controller controls the operation of the linear module and the cylinder.

[0010] When the slider drives the cylinder body to move, the piston rod extends out of the cylinder body and pushes the shielding plate away from the cylinder body. At this time, the shielding plate is facing the induction element and an induction distance is maintained between the shielding plate and the induction element.

[0011] When the induction element senses the shielding plate, the induction element transmits an induction signal to the PLC controller, and the PLC controller controls the information display device to emit a valid signal.

[0012] By adopting the above technical solutions, when the user uses it, the user inputs a command of how much induction distance needs to be adjusted into the PLC controller through the information input device in advance. After the PLC receives this command, it controls the slider to perform a linear motion along the linear guide 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 induction element and make the shielding plate move to the corresponding induction distance. If the induction element is effective, the induction element will sense the shielding plate, and then transmit the induction signal to the PLC controller. The PLC controller controls the information display device to emit a valid signal. If the function of the induction element fails, it will not sense the shielding plate, and no induction signal will be transmitted to the PLC controller, and the information display device will not emit a valid signal.

[0013] Further, the information input device is an information input touch screen.

[0014] By adopting the above technical solutions, the user can click on the information input touch screen to select various commands, and transmit the relevant commands to the PLC controller in a touch selection manner, making the user operation more convenient.

[0015] Further, the shielding plate is an iron plate.

[0016] Further, the induction element is placed on a tooling plate. A plurality of placement grooves are provided on one side of the tooling plate facing the shielding plate, and each placement groove places the induction element.

[0017] By adopting the above technical solution, since a number of placement grooves are provided on the tooling plate, multiple induction elements can be placed on the tooling plate. In this way, when detecting the effectiveness of the induction elements, after the PLC controller adjusts the distance between the shielding plate and the tooling plate through the linear module and the cylinder, multiple induction elements of the same type can be detected simultaneously.

[0018] Furthermore, the induction element is electrically connected to the PLC controller through a wire, and a notch for the wire to pass through is provided at the placement groove.

[0019] For the induction element to transmit the induction signal to the PLC controller, the common method is to electrically connect the induction element and the PLC controller using a wire. By adopting the above technical solution, setting a notch at the placement groove can facilitate the better passage of the wire and prevent the wire from being blocked by the bottom of the placement groove.

[0020] Furthermore, two groups of tooling plates are provided.

[0021] By adopting the above technical solution, setting the tooling plates in two groups is also to increase the number of induction elements of the same type detected simultaneously and improve the work efficiency of employees.

[0022] Furthermore, the information display device is a number of signal lights, and the signal lights correspond to the induction elements one by one.

[0023] By adopting the above technical solution, when the information display device is set as a signal light, the effective signal emitted by the information display device is the light being on. In this way, the user can determine whether the induction element is effective by observing whether the light is on. If a certain induction element is effective, the corresponding signal light of the induction element emits light; if a certain induction element fails, the corresponding signal light of the induction element does not emit light. This enables the user to more intuitively feel whether the induction element is effective and improves the efficiency of the employee during the detection operation.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. By inputting relevant instructions for adjusting the induction distance into the PLC controller through the information input device, controlling the operation of the linear module and the cylinder through the PLC controller to make the shielding plate reach the appropriate position, after the induction element senses the shielding plate, an effective signal is emitted through the information display device, so that the effectiveness of the induction element can be detected more intelligently and accurately, improving the work efficiency of employees; 2. Through the cooperation of the induction element, the PLC controller and the signal light, after detecting the effectiveness of the induction element, the user can immediately and intuitively see the detection result.

Detailed implementation manners

[0032] The following combines the drawings and embodiments to describe the present utility model in detail.

[0033] The present utility model uses terms such as "first", "second", or "third" to distinguish different objects, rather than to describe a specific order.

[0034] 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 element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as limiting the specific protection scope of the present utility model.

[0035] The term "fixed connection" used in the present utility model should be understood in a broad sense, that is, any connection method in which there is no displacement and relative rotation between the two during use.

[0036] See Figure 1 、 Figure 2As shown in the figure, a device for detecting the effectiveness of an induction element includes a detection table 1 and a PLC controller 2. The PLC controller 2 is electrically connected to an information input device and an information display device. Specifically, the information input device is an information input touch screen 3. The PLC controller 2 stores in advance the optimal induction distances for testing various types of induction elements 10, and then displays them on the information input touch screen 3. When the user needs to test a certain type of induction element 10, the user selects that type by clicking on the information input touch screen 3, thereby inputting a command to the PLC controller 2 on how much induction distance needs to be adjusted for that type.

[0037] Specifically, the information display device is several signal lamps 4 arranged on the tabletop of the detection table 1. Each signal lamp 4 corresponds one-to-one to several induction elements 10 to be tested. The signal lamp 4 is used to display whether the induction element 10 is effective after detection. If the induction element 10 is effective, the corresponding signal lamp 4 emits light; if the induction element 10 is ineffective, the corresponding signal lamp 4 does not emit light.

[0038] See Figure 1 、 Figure 3 、 Figure 4 As shown in the figure, a linear module is arranged on the detection table 1. The linear module includes a linear guide rail 5 fixedly connected to the tabletop of the detection table 1. The linear guide rail 5 is perpendicular to the tabletop of the detection table 1. A slider 6 is sleeved on the linear guide rail 5. The linear module is of an existing structure. A thread is provided between the sleeved slider 6 and the linear guide rail 5. A motor is used to drive the linear guide rail 5 to rotate. When the linear guide rail 5 rotates, the slider 6 will move linearly along the linear guide rail 5 on the premise that the slider 6 is restricted by a restricting member and cannot rotate. To facilitate the PLC controller 2 to control the operation of the linear module, the motor that drives the linear guide rail 5 to rotate can be electrically connected to the PLC controller 2.

[0039] A cylinder is arranged at the slider 6. The cylinder is horizontally placed and perpendicular to the linear guide rail 5. The cylinder includes a cylinder body 7 and a piston rod 8. The cylinder body 7 is fixedly connected to the slider 6. One end of the piston rod 8 away from the cylinder body 7 is fixedly connected with a shielding plate 9. The shielding plate 9 is specifically an iron plate placed horizontally. The above cylinder is of an existing structure. The intake and exhaust of the inside of the cylinder body 7 are controlled by opening and closing the solenoid valve of the cylinder, thereby controlling whether the piston rod 8 extends from the cylinder body 7 or retracts into the cylinder body 7. To facilitate the PLC controller 2 to control the operation of the cylinder, the solenoid valve that controls the intake and exhaust of the inside of the cylinder body 7 can be electrically connected to the PLC controller 2.

[0040] A support frame 11 is fixedly connected to the tabletop of the detection table 1. A tooling plate 12 is placed on the support frame 11. A plurality of placement grooves 13 are arranged on the surface of the tooling plate 12 facing the shielding plate 9. Each placement groove 13 places a same type of induction element 10. Each induction element 10 is electrically connected to the PLC controller 2.

[0041] When the user needs to detect the sensing element 10, first place the sensing elements 10 of the same category in the placement slots 13, with one sensing element 10 placed in each placement slot 13. Then, according to the category of the sensing element 10 to be detected, the user clicks and selects on the information input touch screen 3, thereby inputting corresponding commands to the PLC controller 2. After receiving the commands, the PLC controller 2 controls the linear module to operate, causing the slider 6 to move along the linear guide 5, and then driving the cylinder and the shielding plate 9 to move. After moving a certain distance, the PLC controller 2 controls the cylinder to operate, causing the piston rod 8 to extend from the cylinder block 7 and push the shielding plate 9 away from the cylinder block 7. Finally, the shielding plate 9 is located directly above the sensing element 10. At this time, the shielding plate 9 not only faces the sensing element 10 directly, but also the distance between the shielding plate 9 and the sensing element 10 is just the optimal sensing distance for testing the sensing element 10 of this category.

[0042] At this time, if the detected sensing element 10 is effective, it will sense the presence of the shielding plate 9, and then transmit the sensing signal to the PLC controller 2. Then, the PLC controller 2 controls the information display device to emit an effective signal, that is, the signal lamp 4 corresponding to the sensing element 10 lights up. If the detected sensing element 10 fails, the signal lamp 4 corresponding to the sensing element 10 does not light up. The user can know whether the detected sensing element 10 is effective by whether the signal lamp 4 lights up.

[0043] See Figure 5 As shown, generally speaking, for the sensing element 10 to be able to transmit the sensing signal to the PLC controller 2, a common method is to electrically connect the sensing element 10 and the PLC controller 2 using wires. However, if the sensing element 10 is connected to the PLC controller 2 through wires, then when connecting the wires, it is easy to be blocked by the bottom of the placement slot 13. And setting a notch 14 for the wire to pass through at the placement slot 13 in advance can effectively solve this problem.

[0044] See Figure 1 、 Figure 6 As shown, in order to increase the number of detection elements of the same category detected simultaneously, the tooling plate 12 can also be set into two groups.

[0045] The above is only the preferred implementation manner 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 in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
