The invention discloses a tunnel furnace heating unit opening device. The tunnel furnace heating unit opening device comprises a lower machine frame, a supporting rod is installed on the right side of the lower machine frame through a rotation shaft in a rotation mode, a labor-saving support is fixed on the left side of the lower machine frame, the upper end of the labor-saving support is provided with an upper articulated shaft, the upper articulated shaft is connected with a lower articulated shaft through a pull spring, the lower articulated shaft is fixed on the upper portion of the left side of an upper furnace body, the lower portion on the left side of the upper furnace body is connected with the lower machine frame through an upper furnace body hinge chain, the lower portion on the right side of the upper furnace body is provided with a limiting platform, a latch hook is installed at the right end of the limiting platform in a sliding mode, and a locking spring which is used for the return of the latch hook is arranged between the latch hook and the limiting platform. The tunnel furnace heating unit opening device has the advantages of being reasonable in design, simple in structure, stable in operation, labor-saving in opening, low in production cost and convenient to promote and use.
Description
technical field [0001] The invention relates to a mechanical opening device, in particular to an opening device for a heating unit of a tunnel furnace. Background technique [0002] The reflow soldering process is the most important soldering process in the current surface mount technology. It has been widely used in many industries including mobile phones, computers, automotive electronics, control circuits, communications, and LED lighting. More and more electronic components are converted from through-hole to surface mount, and it is an obvious trend in the soldering industry that reflow soldering has replaced wave soldering in a considerable range. At present, the opening mechanism of the reflow soldering upper furnace body is mostly an electric mechanism or a gas spring plus a hydraulic damping system, which has disadvantages such as high cost and complex structure. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming...
