Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, specifically to an adjustable SMT template pneumatic tooling and fixture. Background Technology
[0002] Surface Mount Technology (SMT) is an important technology used in electronics manufacturing. It enables the miniaturization and high density of electronic products by directly mounting electronic components onto the surface of a printed circuit board (PCB). In the SMT production process, the SMT stencil is a key tool used to accurately print solder paste onto the PCB, providing the necessary materials for subsequent component mounting and soldering.
[0003] Existing tooling fixtures are usually designed with fixed dimensions and can only fit specific sizes of stencil frames. Since different models of SMT stencils have different stencil frame sizes, manufacturers need to prepare a variety of tooling fixtures of different sizes to meet production needs. This not only increases production costs but also occupies a lot of storage space. In actual production, operators need to frequently change tooling fixtures according to different stencil frame sizes, which reduces production efficiency.
[0004] To address this, an adjustable SMT template pneumatic tooling fixture is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide an adjustable SMT template pneumatic tooling fixture in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] An adjustable SMT template pneumatic fixture includes a horizontal frame and a vertical frame. The vertical frame is provided with a fixing adjustment mechanism to fix the vertical frame to the top surface of the horizontal frame. The fixing adjustment mechanism is provided with a position adjustment mechanism, and a cylinder is fixedly installed on the surface of the position adjustment mechanism. A clamping component is fixedly installed on the free end of the cylinder so that the cylinder drives the clamping component to fix the SMT template.
[0008] Furthermore, the fixed adjustment mechanism includes a first movable block that is slidably installed in the top groove of the crossbeam, and a first threaded rod is fixedly installed on the top surface of the first movable block. The first threaded rod and the longitudinal frame are movably inserted into each other, and a pressure block is movably sleeved on the surface of the first threaded rod. A first knob is threadedly sleeved on the top end of the first threaded rod.
[0009] Furthermore, the position adjustment mechanism includes a Z-shaped mounting bracket that is slidably sleeved on the surface of the longitudinal frame, and a second movable block is slidably installed in the groove on the side of the longitudinal frame. A second threaded rod is fixedly installed on the end face of the second movable block, and the second threaded rod is movably inserted into the Z-shaped mounting bracket. A second knob is threadedly sleeved on the surface of the second threaded rod, and a cylinder is fixedly installed on the Z-shaped mounting bracket.
[0010] Furthermore, the clamping assembly includes a top seat fixedly installed on the top of the cylinder, a stepped rod movably inserted into the top seat, and a pressure plate fixedly installed at the bottom end of the stepped rod. A spring is sleeved on the surface of the stepped rod, and the two ends of the spring are fixedly installed to the top surface of the top seat and the end surface of the stepped rod, respectively.
[0011] Furthermore, the surface of the Z-shaped mounting bracket is provided with protrusions, and the protrusions on the surface of the Z-shaped mounting bracket are slidably disposed in the grooves on the top surface and side surface of the longitudinal frame, respectively.
[0012] Furthermore, the pressure plate is located above the Z-shaped mounting bracket, and the pressure plate is made of rubber material.
[0013] The beneficial effects of this utility model are as follows:
[0014] The fixed adjustment mechanism allows the longitudinal frame to move and adjust on the top surface of the transverse frame. The position adjustment mechanism moves the cylinder and clamping assembly on the surface of the longitudinal frame, thereby adjusting the position of the position adjustment mechanism and clamping assembly. This allows for adjustment to accommodate the size of the SMT template, ensuring that the position adjustment mechanism and clamping assembly align with the edge of the frame. The cylinder drives the clamping assembly to move vertically downwards, bringing the bottom of the clamping assembly into contact with the top surface of the frame. The elastic part of the clamping assembly prevents excessive pressure from damaging the frame. Attached Figure Description
