Description

TECHNICAL FIELD

[0001] The utility model relates to panel switch technical field, especially a kind of capacitive touch panel switch and MES system electromechanical equipment. BACKGROUND

[0002] With the digital workshop / plant in the industrial internet era manufacturing development today, digital electronic control technology is more and more used in MES system. In manufacturing plant, the front-end data acquisition technology of MES system is an essential key technology, and the manual input of electromechanical equipment state data acquisition is changed into digital intelligent input, which is a key link.

[0003] At present, the running state of electromechanical equipment mostly adopts electromechanical equipment state manual identification board, which is a kind of state board for manual identification, and four states of the equipment are set on it, which are running, waiting for material, maintenance and repair, and the state is switched by manual knob. This electromechanical equipment identification board is not convenient for digital equipment state MES data acquisition, and only manual record and upload MES system can be realized. The function button panel switch uploads the above four states respectively. The equipment state identification and uploading process is time-consuming and laborious, and the convenience is low, and the efficiency is also very low. At present, there is also a kind of thin film switch panel, and the contact button is made of carbon powder material. Since the material is easy to pollute and deteriorate, it is not suitable for long-term use in the environment of the equipment, and there are problems such as short service life of the button, not sensitive after a long time, etc.

[0004] In summary, most of the switch box panel switches adopt button type, knob switch and thin film switch as the electromechanical equipment state acquisition. Due to the non-closed switch and the influence of on-site equipment operating environment factors, the protection level is very low, and sometimes mechanical damage and operation insensitivity occur, especially the state display is not eye-catching, which affects the accuracy of MES system electromechanical equipment state data acquisition. At the same time, the failure of switch box panel switch also brings high maintenance cost and data acquisition is not smooth. UTILITY MODEL CONTENTS

The terms used herein are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0024] In a first aspect, the present application provides a capacitive touch panel switch, please refer to Figure 1 and Figure 2The capacitive touch panel switch comprises a circuit board 100, an outer light-transmitting panel 300 and a plurality of functional button assemblies 200. The circuit board 100 is a PCB circuit board having opposite A and B surfaces. A plurality of capacitive touch sub-panels 110 are mounted on the A surface 110 of the circuit board. Each capacitive touch sub-panel 110 is mounted on the circuit board by means of a through-hole welding needle 111. Each functional button assembly 200 corresponds to each capacitive touch sub-panel 110. Each functional button assembly 200 comprises an LED indicator 210, a backlight plate 220 and an inner light shield 230. The LED indicator 210 is mounted on the B surface of the circuit board 100 and corresponds to each capacitive touch sub-panel 110. The backlight plate 220 is located on the B surface of the circuit board and covers the LED indicator 210 so that the light of each LED indicator is uniformly irradiated outward. The inner light shield 230 is arranged around the backlight plate 220 to prevent the light of the independent switch from scattering onto other button lights. As shown in FIG. 6, the plurality of functional button assemblies 200 comprise at least one of a start button assembly, a standby button assembly, a maintenance button assembly, a debugging button assembly, a line changing button assembly and a reselection button assembly. The start button assembly, the standby button assembly, the maintenance button assembly, the debugging button assembly, the line changing button assembly and the reselection button assembly are used to correspond to start function, standby function, maintenance function, debugging function, line changing function and reselection function, respectively. In addition, the capacitive touch panel switch is configured to be electrically connected to a controller of an MES system electromechanical device to control the corresponding functions of the device.

[0025] The outer light-transmitting panel 300 is arranged on the side of the backlight plate 220 away from the circuit board 100. The outer light-transmitting panel 300 forms a touch area in the corresponding area of each functional button assembly 200. In this way, the user can trigger the corresponding functional button assembly by touching the corresponding touch area with a finger.

[0026] It should be noted that the capacitive touch panel switch realizes the working principle. The technology uses a touch chip device, which is a single-key touch and proximity sensing switch. The chip input electrode can generate a self-capacitance. The self-capacitance button is connected to a single electrode of a capacitive sensor to measure the capacitance C. The value of C is the combined value of the parasitic capacitance Cp formed by the electrode and its surrounding conductor and the parasitic capacitance Cf formed by the electrode and the finger. The size of the capacitance is calculated.

[0027] Capacitance equation calculation Since the surrounding devices are static, Cp is constant, but Cf increases with the approach of the finger to contact and non-contact. By setting a threshold value for the amount of increase in Cf, it can be determined whether the touch panel switch is in an "on" or "off" state. Its use can replace the traditional mechanical switch. The touch switch chip is made of CMOS process, and the chip can be configured in multiple modes through pins and can be used for glass, ceramic, plastic and other medium surfaces.

[0028] Of course, the capacitive touch panel is a structure of the prior art, which can be directly obtained by using commercially available components, and the specific structure thereof will not be described herein. For example, the capacitive touch panel has a touch chip device.

[0029] The capacitive touch panel switch described above triggers the corresponding capacitive touch panel through multiple function button assemblies to realize the function of switch touch action, solves the problems of poor contact, low service life, insensitive key, inaccurate uploading of MES data and the like caused by the touch switch, has relatively good durability, and compared with the traditional toggle switch, the multiple button switches of the present application respectively include a power-on button assembly, a standby button assembly, a maintenance button assembly, a debugging button assembly, a line changing button assembly and a reselection button assembly, and each switch button is separately provided, so that the use is convenient. In addition, the capacitive touch panel switch provided by the present application is very similar to the effect of a touch screen, and the cost is greatly reduced compared with the touch screen.

[0030] In one embodiment, the outer light-transmitting panel is a transparent acrylic plate. In this way, the light-transmitting effect can be further improved. For example, the outer light-transmitting panel has a rectangular shape. For example, the outer light-transmitting panel has a color-printed button indication part formed by color printing in each touch area. For example, each color-printed button indication part has a rectangular shape. In this way, the color printing technology is used to play a light-transmitting and beautiful indication role. Each color-printed button indication part, such as the color-printed indication part with a text diagram "power on" formed in the touch area corresponding to the power-on button assembly, and so on. In this way, it is convenient for users to identify.
