Description
Technical field
The utility model relates to the paste solder printing equipment of pcb board, specifically refers to a kind of stencil printer of scraper X-direction motion.
Background technology
In manufacturing electronic product process, need to adopt surface mounting technology (SMT) that various components and parts are welded on printed circuit board (PCB) (PCB), comparatively conventional surface mount process flow process is: the one side that first need to mount components and parts at PCB need to mount the position coating tin cream of components and parts, and then the components and parts of needs welding are attached on the position that PCB is corresponding, after completing the mounting of components and parts, carry out reflow soldering, so just completed wherein mounting of the upper components and parts of one side of PCB, through completing surface mount after the assay was approved, the tin cream amount of coating is the key factor that affects welding quality, tin cream amount is the shape by the opening design of steel mesh, size and thickness determine.
A series of actions that tin cream is coated on pcb board adopts special equipment to complete, and this equipment is called as stencil printer.In order to improve the tin cream coating efficiency of stencil printer and to improve, apply effect, the applicant has invented pump formula scraper head before this, and this pump formula scraper head is installed on stencil printer and by tin cream and is coated on steel mesh.As shown in Figure 1, pump formula scraper head 10 comprises following structure: the first cavity 13, the second cavity 14, the first pressing plate 15, the first depression bar 11, the second pressing plate 16, the second depression bar 12, nozzle 18.Pump formula scraper head 10 is divided in the first cavity 13 and 14, two cavitys of the second cavity fills tin cream.The first pressing plate 15 is in the interior round elevating movement of the first cavity 13.The first pressing plate 15 connects with the first depression bar 11, and the first depression bar 11 drives the first pressing plate 15 to pressurize to the tin cream in the first cavity 13 by External Force Acting.Same, the second pressing plate 16 is in the interior round elevating movement of the second cavity 14, and the second pressing plate 16 connects with the second depression bar 12, and the second depression bar 12 drives the second pressing plate 16 to pressurize to the tin cream in the second cavity 14 by External Force Acting.When the first depression bar 11 and the second depression bar 12 repeatedly move up and down, the tin cream that is contained in the first cavity 13 and the second cavity 14 is extruded, and by nozzle 18, is sprayed on steel mesh.As shown in Figure 1, first, second depression bar is the tin cream of extrusion packing in first, second cavity being sprayed on steel mesh alternately, thereby guarantee the lasting supply of same quality tin cream, and reduce to greatest extent tin cream waste.
The scraper direction of motion great majority of conventional pcb board stencil printer be take Y direction as moving direction on the market at present, when the scraper of this stencil printer prints on steel mesh, PCB is positioned at the centre position of scraper, steel mesh is fixed between pcb board and scraper, and scraper length should be greater than the length of PCB conventionally, like this when scraper moves, prints on steel mesh, the part that PCB is longer than at two ends, left and right, bottom there is not pcb board to support, also having pcb board and not having the place of pcb board, be highly inconsistent, so various piece pressure is also different.Especially, because pump formula scraper cost is high, and the PCB length of producing is conventionally different in size, can not customize according to pcb board length the pump formula scraper of same size, so when the different pcb board of printing, because pcb board size is inconsistent, can there is no on the steel mesh of part correspondence of pcb board at pcb board two ends residual solder(ing) paste.And As time goes on, the residual tin cream of this part can hardening, thereby have influence on the quality of whole tin cream, must cancel and process, thereby the consumption of the tin cream also increasing.
On the other hand, no matter be the stencil printer of Y direction printing or the stencil printer of X-direction printing on the market, its scraper installation direction is all parallel with the limit of most of steel mesh perforates, when scraper moves brush tin with certain movement direction on steel mesh, perforate on steel mesh may hinder to some extent to scraper, especially larger cubic hole, when the limit parallel with scraper, hole upwarps, as if the left side of square bar mesh upwarps, when scraper is scraped in the past from right to left, wing and the limit, hole upwarping can produce active force, may destroy steel mesh hole or wing.
