A chip resistor printing device

Abstract

The invention discloses a chip resistance printing device, which comprises a printing device casing, the top outer surface of the printing device casing is close to both sides, and an operation platform is fixed by bolts, and the top outer surface of the printing device casing is close to the rear end. A printing machine is installed in a movable position, and a warning light is installed on the outer surface of the top of the printing machine near the rear end through bolts. A chip resistor printing device according to the present invention, first of all, can repair and observe each component and circuit board more intuitively, by installing the wires of the components in the inside of the wire discharge slot from the wire slot, it is convenient for each wire Carry out investigation and testing to avoid cross-connection of wires between components to affect observation. Secondly, it can improve the pass rate of resistor printing, avoid drying too fast to cause cracks inside the resistor material, etc., and can also print more accurately to avoid printing misalignment. Bring better prospects for use.

Description

technical field [0001] The invention relates to the field of resistance printing devices, in particular to a chip resistance printing device. Background technique [0002] SMD resistors, also known as chip fixed resistors, are one of the metal glass uranium resistors. The resistors are mixed with metal powder and glass uranium and printed on the substrate by screen printing. They have moisture resistance. , High temperature coefficient is small, widely used; [0003] There are certain disadvantages in the existing chip resistance printing device in use, (1), during maintenance, it is necessary to first remove the printing device shell on one side of the resistance printing device, and then repair the inside of the device, because each component and circuit They are all installed inside the device, and the space inside the device is limited, so it is difficult to observe and repair the internal device. At the same time, because the internal parts of the device overlap each o...

Problems solved by technology

[0003] There are certain disadvantages in the existing chip resistance printing device in use, (1), during maintenance, it is necessary to first remove the printing device shell on one side of the resistance printing device, and then repair the inside of the device, because each component and circuit They are all installed inside the device, and the space inside the device is limited, so it is difficult to observe and repair the internal device. At the same time, because the internal parts of the device overlap each other, the use of tools is affected. Secondly, the internal lines of the device are interlaced, which further increases the maintenance (2) For the first piece, use measuring equipment such as a microscope or a projector to determine whether the printing position is correct. Batch printing depends on the unprepared repeated positioning accuracy to complete, and random checks are made during the process. Occasional poor printing positions and poor appearance during the process It cannot be found in time, and the debugging of the first piece is time-consuming and laborious. The accumulated experience of the operator is used to operate, and the technical requirements for the operator are high. During the printing process, the printing position and appearance of the product cannot be monitored in real time for defects; (3). Dry the resistance material, the material is easy to absorb heat and dry quickly, the material is dried too fast, the internal material distribution is uneven, and the internal cracks are easy to appear, which affects the service life and safety of the printed resistance, and reduces the pass rate and causes waste of resources. , we propose a chip resistor printing device
