In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.
[0027] Example, see Figure 1, a digital display device includes a main board 8 and a digital tube display board 1. The main board 8 is provided with mounting holes 7, and each mounting hole 7 is equipped with a connector. The connector includes an adhesive plate 5, and a stud 6 is fixed in the middle of the adhesive plate 5. The stud 6 is equipped with a locking nut. By directly bonding the adhesive plate 5 to the inner wall of the projection welding device shell, and then fixing the main board 8 to the adhesive plate 5, the main board 8 can be fixed. The fixing position can be adjusted at will. It can be fixed at any position where there is a gap between the projection welding shell and the internal components. The main board 8 is partially fixed to the inside of the projection welding device. The auxiliary equipment needs to be equipped with a separate shell. The main board 8 and the digital tube display board 1 need to be installed in the shell before leaving the factory, which will increase the production cost of the auxiliary equipment.
[0028] A digital tube display board wiring connector 9 is welded on the main board 8, and the digital tube display board 1 is connected to a plug connector through a wire. The plug connector is adapted to the digital tube display board wiring connector 9, and the digital tube display board 1 is directly connected to the main board 8 through the plug connector, so that the digital tube display board 1 can display.
[0029] The digital tube display board 1 is equipped with a limit frame 2, and the limit frame 2 is provided with a limit space adapted to the digital tube display board 1. The limit space prevents the digital tube display board 1 from escaping from the limit frame 2. The lower side of the limit frame 2 is also provided with a connecting skirt 3 that is folded outward horizontally. The connecting skirt 3 is fixedly connected to the device shell by gluing or magnetic attraction. The digital tube display board 1 can be directly fixed to the surface of the projection welding device shell by gluing, which can improve stability, but it is not convenient to replace the digital tube display board 1 later. Alternatively, the digital tube display board 1 can also be limited by the magnetic attraction part in this application, and for the limit frame 2, it can be enclosed in a frame shape as in this application and form a limit space with the projection welding device shell to limit the digital tube display board 1. A socket can also be opened on one side to facilitate the insertion or removal of the digital tube display board 1, and a display window is formed on the surface of the limit frame 2 for the digital tube display board 1 to display, so that the digital tube display board 1 can be limited and fixed without affecting the display function of the digital tube display board 1.
[0030] A wire hole 4 is provided on one side of the limit frame 2, so as to facilitate the arrangement of the wires of the digital tube display board 1. Furthermore, a buried wire pipe can be provided for the wires to pass through. At the same time, a magnetic attraction or adhesive part is provided at the bottom of the buried wire pipe to fix it to the shell surface of the projection welding device, so that the wires of the digital tube display board 1 can be arranged and fixed.
[0031] The digital tube display board 1 is provided with multiple LED digital tubes for displaying numbers, letters or symbols. The main board 8 is composed of a microcontroller circuit, an interface circuit, and a software burning circuit to realize output control, input acquisition, drive display, logic conversion, and decoding functions. The main board 8 is powered by the power terminal GND ground wire and VCC and +24V. The main board 8 receives 8421BCD code input, which is a binary-coded decimal representation method that can directly convert and display decimal numbers. The main board 8 has 1248DP+X1, X2, X3, X4 bit select input ports for selecting which digital tube to display. Data is input through the 8421BCD code port and combined with the bit select signal to realize the display of a specific number on a specific digital tube. The main board 8 is provided with a 485Modbus ASCII communication function to realize remote data transmission and display control.
[0032] Taking the 4-digit digital tube displaying the number 1234 as an example, the specific steps are as follows: set all bit selection signals (X1, X2, X3, X4) to low level to ensure that no digital tube is selected at the beginning, set the 8421BCD code port to 0001 (binary representation of 1), set the first bit selection signal X1 to high level (pulse signal, first high and then low), activate the first digital tube to display the number 1, change the 8421BCD code port to 0010 (binary representation of 2), and set the second bit selection signal X2 to high level. Level (pulse signal), activate the second digital tube to display the number 2, change the 8421BCD code port to 0011 (binary representation 3), set the third bit selection signal X3 to high level (pulse signal), activate the third digital tube to display the number 3, change the 8421BCD code port to 0100 (binary representation 4), set the fourth bit selection signal X4 to high level (pulse signal), activate the fourth digital tube to display the number 4. When implementing the communication function, you must ensure that the PLC or host computer software supports the Modbus ASCII protocol and correctly configure the communication parameters.
[0033] A device for detecting and preventing errors in program numbers of projection welding equipment, in which the program number signal inside the projection welding equipment is connected to a main board 8 and a signal is connected to a digital display device, an adhesive board 5 is pasted on the inner wall of the projection welding equipment shell, and the main board 8 is fixed on the adhesive board 5, and the main board 8 is connected to a digital tube display board 1 placed on the outside of the projection welding equipment through a digital tube display board wiring connector 9. On the one hand, this improves the convenience of installation. If auxiliary equipment is directly installed, the auxiliary equipment needs to be connected to the projection welding equipment first, and the projection welding equipment shell needs to be punched at the same time, and then the auxiliary equipment is fixed to the projection welding equipment shell, and the installation is not convenient enough; on the other hand, a large protrusion will be formed on the outside of the projection welding equipment. When the projection welding equipment is stored and transported, the auxiliary equipment is easily bumped, thereby causing the auxiliary equipment to separate and be damaged from the projection welding equipment, and affecting the original appearance of the projection welding equipment, which appears cumbersome.
[0034] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The embodiments of the present utility model and the features of the embodiments can be combined with each other unless there is a conflict. Therefore, the scope of protection of the present utility model shall be based on the scope of protection of the claims.
