Description

Technical Field

[0001] This utility model relates to the field of SMT processing technology, specifically to an adjustable workbench for SMT circuit board production. 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 surface mount technology and one of the most popular technologies and processes in the electronics assembly industry.

[0003] Soldering is a common step in the circuit board processing. Generally, soldering is done fully automatically using large automated machinery, but this is costly. Some small factories, when faced with orders with small production volumes that cannot be processed by large equipment, require separate workbenches for individual soldering operations. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable workbench for SMT circuit board production, which is simple to operate and has a split upper and lower design, making it convenient for workers to use and replace components, and has good performance.

[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable SMT circuit board production workbench, including a frame and a workbench. A clamping assembly is provided on the workbench. An electrode mounting plate and a cylinder fixing plate are provided on the frame near the workbench. A lifting cylinder is provided on the cylinder fixing plate. An electrode seat is provided at the output end of the lifting cylinder. The electrode mounting plate is connected to the electrode seat through a copper strip. An electrode arm and an electrode head corresponding to the clamping assembly are provided at the bottom of the electrode seat.

[0006] Furthermore, the clamping assembly includes a fixed base, an insulating plate is provided on the side of the fixed base, a placement seat is provided on the fixed base, and limit seats are provided on both sides of the placement seat. The limit seats are fixed by screws, a placement groove is provided at the center of the placement seat, and an adjustment block is provided on the limit seat corresponding to the position of the placement groove.

[0007] Furthermore, the upper surface of the fixed base is provided with a vertical plate on one side of the placement seat, a clamping cylinder is provided on the vertical plate, the output end of the clamping cylinder is provided with a pressure arm corresponding to one of the limiting seats, a pressure block seat is provided on the vertical plate, and the pressure block seat is connected to the center position of the pressure arm through a connecting plate, and both sides of the connecting plate are connected by pins.

[0008] Furthermore, an AC transformer connected to the electrode mounting plate is provided on the back of the frame.

[0009] Furthermore, safety light curtains are installed on both sides of the workbench.

[0010] Furthermore, the copper strip is connected to the electrode mounting plate via a pressure plate and to the electrode base via a copper busbar.

[0011] The beneficial effects of this utility model are as follows: When using this device, the workpiece to be welded is first placed in the placement slot on the placement seat. The placement seat is limited by the limiting seats on both sides. At the same time, the adjusting blocks on the limiting seats can be adjusted according to the size of the workpiece, thereby limiting the workpiece on both sides. After the limiting is completed, the clamping cylinder is activated, which drives the pressure arm to move. The center position of the pressure arm is connected to the pressure block seat through the connecting plate, that is, the pressure arm can rotate along the connection point until the end of the pressure arm presses against the side limiting block to achieve the double limiting effect. After the limiting is completed, the lifting cylinder at the top is activated to energize the electrode mounting plate, which can drive the bottom electrode arm and electrode head to perform welding operations on the workpiece. The operation is simple and the upper and lower separation design makes it convenient for workers to use and replace components. The effect of use is good. Attached Figure Description

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.

[0018] 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.

[0019] 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.

[0020] 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.
