Description

Technical Field

[0001] This utility model relates to the field of SMT processing technology, specifically to a bottom positioning component for a fully automated SMT laser welding production line. Background Technology

[0002] SMT (Surface Mount Technology) is an abbreviation for a series of processes performed on a PCB (Printed Circuit Board). SMT is a technology and process that is most popular in the electronics assembly industry.

[0003] Welding is a common step in the processing. The typical welding base fixes the workpiece by fixing it on both sides. This fixing method is not very secure and the workpiece may shift during welding. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a bottom positioning component for a fully automatic SMT laser welding production line. It has a simple structure and can clamp and fix the workpiece from four positions: top, bottom, end, and side. It has strong adaptability and will not shift during subsequent processing.

[0005] To solve the above-mentioned technical problems, this utility model provides a bottom positioning component for a fully automatic SMT laser welding production line. The component includes a welding table with symmetrical clamping assemblies. Each clamping assembly includes a module positioning block, a surface positioning block, and a side positioning block. A positioning cylinder is mounted on the module positioning block, and a support is mounted at the output end of the positioning cylinder. A surface cylinder is mounted on the surface positioning block, and an end face pressure plate is mounted at the output end of the surface cylinder. A side cylinder is mounted on the side positioning block, and a side pressure plate is mounted at the output end of the side cylinder.

[0006] Furthermore, the support member has an inwardly oriented guide block on its side.

[0007] Furthermore, it includes a top positioning block, on which a mounting plate is provided, and on which a top pressure cylinder is provided. The output end of the top pressure cylinder is provided with a pressure arm, and the pressure arm is provided with a rubber pressure head. The mounting plate is provided with a U-shaped ear plate, and a connecting arm is provided at the center of the pressure arm and connected to the U-shaped ear plate. Both sides of the connecting arm are connected by pins.

[0008] Furthermore, it includes a support frame, wherein the support frame is provided with legs at the bottom and a partition in the middle.

[0009] Furthermore, a control panel is provided on the side of the welding table, and a power distribution box connected to the control panel is provided at the bottom of the support frame.

[0010] The beneficial effects of this utility model are as follows: When using this device, the workpiece to be processed is placed between two clamping components. The positioning cylinder drives the support to move back and forth to adjust and achieve the supporting effect. After the adjustment is completed, the starting cylinder drives the end face pressure plate to move until both ends of the workpiece are pressed tightly. Then, the side cylinder is started to drive the side pressure plate to press the side of the workpiece. Finally, the top pressing cylinder is started, which drives the pressure arm to move (the pins on both sides of the connecting arm ensure that there is no resistance during the movement of the pressure arm and that it will rotate continuously), driving the rubber pressure head to press and fix the top of the workpiece, realizing fixed positioning in four directions, and the use effect is good.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0019] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
