Description

Technical Field

[0001] The invention relates to the technical field of soldering equipment, in particular to a closed PCB soldering equipment. Background Art

[0002] Before the emergence of printed circuit boards, the interconnection between electronic components was based on direct connection of wires to form a complete circuit. In modern times, circuit panels only exist as effective experimental tools, while printed circuit boards have become an absolute dominant position in the electronics industry. Printed circuit boards have developed from single-layer to double-layer, multi-layer and flexible boards, and are constantly developing towards high precision, high density and high reliability. Continuously reducing the size, reducing costs and improving performance will enable printed circuit boards to maintain strong vitality in the development of future electronic products. The future development trend of printed circuit board production and manufacturing technology is to develop in the direction of high density, high precision, fine aperture, fine wire, small spacing, high reliability, multi-layer, high-speed transmission, light weight and thinness in terms of performance.

[0003] The welding gun head of the soldering equipment often generates high heat, which can easily cause burns or fire when used by unauthorized personnel. Therefore, a closed box structure is required to prevent unauthorized personnel from using the soldering equipment. At the same time, a modern lock is also used on the box structure, such as a lock composed of a card reader and a magnetic card, or a mechanical lock that requires a key to open. However, no matter which method is used, there is a problem of easy loss of keys. In reality, keys or magnetic cards are occasionally lost, and the door of the soldering equipment cannot be opened directly and quickly. At this time, although the lock structure will prevent unauthorized personnel from opening the soldering equipment, it will also hinder the operator from using the equipment. However, if no lock is provided, the door of the soldering equipment is extremely easy to be opened, and the existing equipment cannot maintain the convenience of opening the soldering equipment while preventing unauthorized personnel from opening the soldering equipment.

When the five fingers completely enter the rotating part, the end of the extension rod away from the rectangular sleeve is flush and pushes the limit part away from the hook part. The non-operating personnel cannot completely separate the limit part from the hook part due to the incompatibility of finger length. The operator then rotates his right hand, and the extension rod applies torque to the hook part, so that the hook part rotates and separates from the card holder. The present invention uses a double lock structure to lock the door body. The double lock structure can be opened by swiping a card. In the case of forgetting to bring the magnetic card, the designated operator with recorded hand shape can also complete emergency unlocking by squeezing the top pressure piece with fingers and twisting the rotating part. This ensures that unrelated personnel cannot unlock the door at will, and also ensures that in the case of forgetting to bring the magnetic card, the operator can directly unlock the door by hand, which is very convenient.

[0032] A double lock structure 3 is installed between the cabinet 1 and the door body 2, and the double lock structure 3 includes a card frame 4 fixedly connected to the door body 2. A shell 5 is installed on the cabinet 1, and a cover plate is detachably installed on the shell 5. A rotating part 6 is installed in the shell 5, and five groups of top pressure pieces 7 are slidably installed on the rotating part 6.

An extension rod 10 is slidably installed on the rectangular sleeve 9, and a limited length plug-in 11 is movably installed between the extension rod 10 and the rectangular sleeve 9. The length of the limited length plug-in 11 is different, and the length of the extension rod 10 extending from the rectangular sleeve 9 is also different, so that the length of the extension rod 10 extending is adapted to the finger length of the specially tested personnel, and the rectangular sleeve 9 is slidably connected to a guide seat 12, and the guide seat 12 is connected to the connecting A first spring is installed between the sheets 8, the guide seat 12 is fixedly connected with a rotating seat 13, the rotating seat 13 is slidably connected with a guide rail 14 fixedly connected with the shell 5, a hooking portion 15 movably connected with the card holder 4 is installed in the shell 5, the hooking portion 15 is movably connected with a limiting portion 16, when the five groups of extension rods 10 push the limiting portion 16 away from the hooking portion 15, the extension rods 10 provide a torque for the rotation of the hooking portion 15, an active pushing mechanism 17 is installed in the shell 5, the active pushing mechanism 17 is slidably connected with the hooking portion 15, a control module 18 is installed on the cabinet 1, a card reader 19 connected to the control module 18 for communication is fixedly installed on the cabinet 1, the card reader 19 is used to read a magnetic card, and the active pushing mechanism 17 and the limiting portion 16 are both connected to the control module 18 for communication;
