Problems solved by technology
[0002] Chip resistors, also known as chip fixed resistors, are one of the metal glass glaze resistors. They are resistant to humidity and high temperature, and have a small temperature coefficient, which can greatly save circuit space costs and make the design more refined. However, traditional chip resistors When the chip resistor is soldered to the PCB board, it is necessary to fix the chip resistor with tweezers and press it to the soldering point. Because of its small size, it is easy to lose, and it is easy to cause uneven soldering during soldering.

Embodiment Construction
[0025] The following will be combined with the Figure 1 to Figure 5 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. For ease of introduction, the specific form of the spring connection is not described below, which can adopt the conventional setting method in the mechanical design manual, that is, grooves or protrusions are provided to position the spring.
[0026] like Figure 1-5 As shown, a chip resistor and PCB board welding device includes a housing 35, a square housing 10 is fixed on the left end of the housing 35, a working cha...

The invention discloses a chip resistor and PCB welding device. The chip resistor and PCB welding device comprises a shell, a square shell body is fixedly arranged on the left end surface of the shell, a working cavity is formed in the shell, a tabletting mechanism is arranged in the middle in the working cavity, a spinning mechanism is arranged on the right end wall of the working cavity, and a conveying mechanism is arranged on the square shell body. According to the chip resistor and PCB welding device, by arranging the conveying mechanism, a chip resistor can be flatly pressed to a printedcircuit board welding point, the phenomenon that the chip resistor is lost in the welding process or is placed obliquely to affect the quality of the printed circuit board can be avoided, spot welding and chip resistor welding can be completed at a time after a spinning electrode is arranged, and the phenomena that spot welding tin is solidified due to the facts that spot welding is conducted firstly and then the chip resistor is taken out, and the printed circuit board is damaged due to the fact that the pot welding tin needs to be re-liquefied can be avoided.
Description
technical field [0001] The present invention belongs to the electronic field of the present invention, and in particular relates to a chip resistor and PCB board welding device and a use method thereof. Background technique [0002] SMD resistors, also known as chip fixed resistors, are one of the metal glass glaze resistors. They are resistant to humidity and high temperature, and have a small temperature coefficient, which can greatly save circuit space costs and make the design more refined. However, the traditional chip resistors When the chip resistor is soldered to the PCB board, it is necessary to fix the chip resistor with tweezers and press it to the soldering point. Because of its small size, it is easy to lose, and it is easy to cause uneven soldering during soldering. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a chip resistor and PCB board welding device and its use method, which aut...
