Problems solved by technology

[0004] In the basic process of SMT above, the equipment used in the silk screen printing process is a screen printing machine. However, the use of a screen printing machine has certain disadvantages. The uniformity of the solder paste dripped on the PCB board through the screen printing machine is poor, which is easy to cause due to excessive dripping. Lead to the waste of solder paste, or cause poor connection between SMT parts and PCB boards, thereby reducing product quality and resulting in waste of resources

Abstract

The invention discloses an automatic tin adding machine, which comprises a controller, a horizontal transmission mechanism and an automatic tin adding mechanism. The automatic tin adding mechanism is connected with the horizontal transmission mechanism via a connecting support and comprises a vertical transmission mechanism, a squeezing flange and a fixing flange, the vertical transmission mechanism is connected with the connecting support, the squeezing flange is connected with the vertical transmission mechanism and used for downwards squeezing a tin cream box, the fixing flange is connected with the connecting support and used for fixing the tin cream box, and the horizontal transmission mechanism and the vertical transmission mechanism are electrically connected with the controller. The automatic tin adding machine can achieve purposes of uniformly squeezing out tin cream, increasing the quality of products and saves resources.

Description

technical field [0001] The invention relates to an electronic assembly machine, in particular to a screen printing device, in particular to an automatic tinning machine. Background technique [0002] At present, surface mount technology SMT is the most popular technology and process in the electronic assembly industry, which has many advantages such as high assembly density, small size and light weight of electronic products. [0003] The elements of the basic SMT process include: silk screen printing (or dispensing) - placement - (curing) - reflow soldering - cleaning - testing - repair. Among them, the role of silk screen printing is to leak solder paste or patch glue onto the pads of the printed circuit board PCB to prepare for the welding of components; and then accurately install the surface mount components on the PCB board through the mounting process In a fixed position, the patch adhesive or solder paste is melted by curing or reflow soldering, so that the surface ...
