Abstract

The invention provides a placement machine, comprising a placement machine body, first guide rails are provided on both sides of the placement machine body, moving columns are slidably installed on the two first guide rails, and a moving column is fixed between the two moving columns. The second guide rail is slidingly connected with the mounting head; the conveying slide rail is arranged under the mounting head, and the conveying platform is slidably installed on the conveying slide rail, and the carrying platform is detachably connected to the conveying platform through a shock absorbing mechanism; The shock mechanism includes a cylinder, a push rod and a damping spring. The upper end of the push rod is provided with a block; the bearing table is provided with a first installation groove and a second installation groove matching the shape of the upper end of the push rod. The clamping block passes through the second installation groove and snaps into the first installation groove; the two sides of the carrying platform are provided with a fixing mechanism, and the fixing mechanism includes a fixing seat, a pull plate, a fixing plate and a tension spring; Shock, which effectively slows down the vibration generated during the mounting process, reduces the damage caused by the vibration, and improves the mounting quality.

Description

technical field

[0001] The invention relates to the field of circuit board processing, in particular to a placement machine. Background technique

[0002] SMD is a circuit assembly technology that mounts non-lead or short-lead surface mount components on the surface of a printed circuit board or other substrates, and solders and assembles them by reflow soldering or dip soldering. During the placement process, since the component is pressed on the substrate from the z-axis direction under the action of a certain amount of placement force and is stuck by viscous media such as solder paste and adhesive or flux, the suction of the placement head The nozzle will press the substrate down; and now the placement machine is more and more efficient, and the assembly speed of the suction nozzle used to pick up the components to be mounted on the placement head has also become very fast, so that the substrate will also Vibration is generated under the impact of each assembly; on the o...
