Description

A kind of pcb board material cutting machine servicing unit

Technical field

The utility model relates to a kind of cutting machine servicing unit, is specifically related to a kind of pcb board material cutting machine servicing unit.

Technical background

Cutting out plate, is that PCB manufactures a very important production process in the process, and it mainly acts on is that material plate is cut into the production size; The material plate size that buying is returned is very big; Be not suitable for manufacturing process, the important procedure so the sanction plate is absolutely necessary, the size of producing plate in process of production is to form according to the finished size layout; Therefore, the cutting of board dimension must be in strict accordance with requiring.At present, increasingly mature along with production technology, various sheet cutting machine automation degree of equipment are also perfect day by day; In the process of cutting, need sheet material be advanced to cutting machine,, be the production board size between two groups of cuttves through cutter cutting up and down; Smooth because of roller surface, the sheet material of cutting can produce the displacement phenomenon along with up and down cutter is movable, and deviation appears in the tilt production board size of back cutting of sheet material; Thereby scrappage is promoted; Cost increases, in case sheet material cutting problem occurs if sheet material lacks, then might influence manufacturing schedule.

The utility model content

The purpose of the utility model is to provide a kind of pcb board material cutting machine servicing unit, avoids in cutting process sheet material to tilt and causes the production dimensional discrepancy.

For realizing this purpose, the utility model has adopted following technical scheme:

A kind of pcb board material cutting machine servicing unit; Comprise main engine bed, roller bearing and cutter; Said roller bearing is located in the said main engine bed, and said roller bearing comprises the last roller bearing and following roller bearing that is parallel to each other, and the said roller bearing of going up comprises mutual corresponding combination cutter at interval with following roller bearing; Said roller bearing also comprises the combination slipmat of mutual correspondence, and said combination slipmat is located at the zone at interval between the combination cutter.

Further technological improvement; In the utility model, said combination cutter are three groups, its be followed successively by upper left cutter and a left side down cutter, in go up cutter and in cutter, upper right cutter and bottom right cutter down; The zone at interval is two between said three groups of combination cutter; Cutter position is guaranteed up and down, and the cutting accuracy of sheet material just can improve, and cutting can be enhanced productivity simultaneously up and down.

Further technological improvement, in the utility model, the distance of two interval regions equates between said three groups of combination cutter.

Further technological improvement, in the utility model, said combination slipmat is the annular elastic gel, elastic gel can reduce the probability that sheet material damages, and strengthens advancing the speed of plate, simultaneously, can avoid offset.

Further technological improvement, in the utility model, said combination slipmat is fixed on the roller bearing, can be according to the convenient adjustment of board materials production size position, the slipmat of damaging after service time is long uses the solid mode of cover also to change more easily and maintenance.

The utility model contrast prior art has following advantage: can avoid the offset of sheet material in cutting process, improve cutting accuracy, speed production efficient with save production cost, simple in structure, easy to operate, it is strong to implement row and generalization.

Description of drawings

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model user mode figure.

The specific embodiment

Existing with reference to accompanying drawing, further explain the utility model.

Like Fig. 1, shown in 2, a kind of pcb board material cutting machine servicing unit; Comprise main engine bed 1, roller bearing 2 and cutter 3; Roller bearing 2 is located in the said main engine bed 1, and roller bearing 1 comprises the last roller bearing 11 and following roller bearing 12 that is parallel to each other, and last roller bearing 11 comprises mutual corresponding combination cutter 3 at interval with following roller bearing 12; Roller bearing 2 also comprises the combination slipmat 4 of mutual correspondence, and combination slipmat 4 is located at the zone at interval between the combination cutter 3.

Combination cutter 3 are three groups; It is followed successively by upper left cutter 311 and a left side down cutter 312, in go up cutter 321 and in cutter 322, upper right cutter 331 and bottom right cutter 332 down; Three groups of zones of making up interval between the cutter 3 are two; Three groups of distances that make up two interval regions between the cutter 3 equate that three groups of distances that make up between the cutter 3 are adjusted according to the size of producing plate, and cutter position is guaranteed unanimity up and down; The cutting accuracy of sheet material just can improve, and cutting can be enhanced productivity simultaneously up and down.

Combination slipmat 4 is the annular elastic gel, and elastic gel can reduce the probability that sheet material damages, and strengthens advancing the speed of plate, simultaneously, can avoid offset.

Combination slipmat 4 is fixed on the roller bearing 2, can overlap also easier replacing of solid mode and the maintenance long combination slipmat 4 of damage later on service time according to the convenient position of adjusting of board materials production size.

The utility model starts cutting machine before according to the interval between the production size adjusting cutter when work, the sheet material 5 that operating personnel will cut is placed into main engine bed 1; Sheet material 5 is pushed cutting machine, and last roller bearing 11 rotates, and following roller bearing 12 scrolls up; Roller bearing 2 rotating directions inwardly form an impetus; Cut thereby can promote sheet material 5, combination cutter 3 are fixed on the roller bearing 2 with combination slipmat 4, and rotating direction is consistent with roller bearing 2; Sheet material 5 through the effect of cutter up and down, is accomplished sheet material 5 cuttings in pushing course.

Above-described the utility model embodiment does not constitute the qualification to the utility model protection domain.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the claim protection domain of the utility model.
