Abstract
The utility model discloses a baking board rack structure for a large board, which comprises a supporting main body, an upper fixing rack and a lower fixing rack, wherein the upper fixing rack is erected at the uppermost end of the supporting main body, and the lower fixing rack is erected in the middle of the supporting main body. When the baking board rack structure for the large board is in use, the upper edge of the large board is fixed on the upper fixing rack of the baking board rack structure by using a copper wire and is fixed in an auxiliary way by using a strong clip; the lower fixing rack is adjusted, so that the lower fixing rack is slightly lower than the lower edge of the large board; the copper wire is penetrated through a hole on the large board; and the lower edge of the large board is fixed on the lower fixing rack of a baking board rack. The baking board rack structure fixes the upper edge and the lower edge of the large board; and compared with the fixation of the left edge and the right edge of the large board by a conventional baking board rack, the large board cannot be suffered from extrusion force from the left edge and the right edge, and the middle part of the large board is difficult to be extruded to deform. The space of each board of the baking board rack structure is about 170 mm so as to guarantee that any two boards cannot be in contact with each other in a board baking process, thereby avoiding the conditions of abrasion marks by solder mask ink and the adhesion of the two boards.

The utility model content
The purpose of the utility model is to provide a kind of big plate to bake framed plate structure; It can overcome above-mentioned defective; Can bake plate greater than the wiring board of 620mm * 620mm to size, and solve the difficult fixing big plate of existing roasting grillage, be prone to make the plate distortion, make the coherent problem of plate easily.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of big plate is baked framed plate structure; It is characterized in that: it comprises supportive body, upper holder and lower fixed frame; Described upper holder is located at the top of described supportive body, and described lower fixed frame is located at the mid portion of described supportive body.
Above-mentioned supportive body comprises base for supporting and main body frame, and described base for supporting is located at the bottom of main body frame.
Above-mentioned supportive body is that stainless steel tube is made.
Above-mentioned upper holder is made by iron wire or steel wire.
Above-mentioned upper holder is that iron wire or the steel wire of 8mm is made by diameter.
Above-mentioned lower fixed frame is made by iron wire or steel wire.
Above-mentioned lower fixed frame is that iron wire or the steel wire of 8mm is made by diameter.
Above-mentioned a kind of big plate is baked framed plate structure, and it also further includes regulates the sleeve structure that described lower fixed frame moves up and down.
Preferably, above-mentioned sleeve structure is four groups, is located at respectively on described four angles that comprise base for supporting.
Preferably, above-mentioned sleeve structure comprises support bar, sleeve pipe and locking part, and the upper end of described support bar and described main body frame set firmly; Lower end and described base for supporting set firmly, and described casing pipe sleeve is located on the described support bar, and described sleeve pipe and described lower fixed frame set firmly; Described sleeve pipe is provided with fixing hole; Described fixing hole is provided with internal thread, and described locking part is provided with external screw thread, and the internal thread on the described fixing hole matches with external screw thread on the described locking part.
After adopting technique scheme, during use, be fixed on this novel upper holder with the top of copper wire with big plate, and with powerful clip auxiliary fixing; The adjustment lower fixed frame makes it the lower limb a little less than big plate, passes the hole on the big plate with copper wire, big plate lower limb is fixed on the lower fixed frame of roasting grillage; This novel fixing be the both sides up and down of big plate, with the roasting plate cage of tradition fixedly the right and left compare, plate can not receive the extruding force on both sides greatly, the centre is not easy to be extruded distortion.The spacing of every plate that this is novel is about 170mm, can not contact in roasting plate process to guarantee any two plates, thereby avoid hindering the generation that the solder paste China ink is wiped flower and two coherent situation of plate.Compare with commonly using, this novel equipment can guarantee the smooth of plate carrying out the fixing and roasting plate of larger size panel (size is greater than the plate of 620mm * 6200mm), and no adhesion does not have quality abnormals such as the flower of wiping.
Description of drawings
