Description
Technical field
The present invention relates to the processing and manufacturing of wiring board, specifically refer to printed circuit board retaining device.
Background technology
PCB Chinese is " printed circuit board ", also known as printed circuit board (PCB), printed substrate, is important electronic unit,
It is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.Owing to it is to use electron printing (i.e.
SMT) make, therefore be referred to as " printing " circuit board.
In prior art, when PCB plate enters chip mounter printing tin cream operation, pcb board supports below location structure existence
Technological deficiency: 1, this support location structure relies solely on support pcb board two ends and realizes the support location of monoblock P plate, pcb board
Middle-end is in vacant state.When supplied materials uses this structure to support location without the pcb board deformed, unsettled owing to being in the middle part of pcb board
State, is affected by gravity, and pcb board middle part and tin cream web plate laminating degree are far below pcb board two ends, pcb board when tin cream is printed
Middle part tin cream thickness, easily beyond technological standards, causes component's feet short circuit, produces defective products；2, part pcb board comes
The trace concave change shape meeting process parameter variation scope is there is during material, when using this to support location structure support location pcb board,
Owing to only supporting pcb board two ends, location, pcb board middle part is caused to have one owing to there is trace concave change shape with tin cream web plate
Fixed gap, when tin cream is printed, the far super technological standards allowed of pcb board middle part tin cream thickness, easily causes component's feet
Short circuit, produces defective products.
Therefore, the SMT equipment in prior art that how to solve supports the pcb board middle part that the structure of location pcb board exists
The pcb board middle part tin cream printing amount that cannot fit tightly with tin cream web plate and cause is blocked up causes what defective products produced to ask
Topic, becomes those skilled in the art's important technological problems to be solved.
Summary of the invention
It is an object of the invention to provide printed circuit board retaining device, solve SMT equipment to use in current industry
That states that pcb board supports that location structure exists causes in the middle of pcb board because of pcb board self gravitation or because pcb board exists trace concave change shape
Position cannot fit tightly with tin cream web plate, causes tin cream to be printed and blocked up causes component's feet short circuit to produce the asking of defective products
Topic.
The purpose of the present invention is achieved through the following technical solutions:
Printed circuit board retaining device, including the base plate of rectangle, is respectively arranged with stripe board on two long limits of described base plate,
And on the sidewall that two stripe board are relative, reinforcing plate is installed, described reinforcing plate has and multiple are arranged side by side and are perpendicular to
The draw-in groove of stripe board, the two ends of dividing plate are respectively placed in two draw-in grooves being oppositely arranged；Along the short side direction of described base plate, the end of at
Having multiple pore side by side on plate, and multiple described pore is between two adjacent draw-in grooves, multiple pores pass through flexible pipe
It is connected with air pump.
During use, base plate is provided with on the outfan of cylinder, and web plate is fixed on the top of two stripe board, multiple demarcation strips
Upper surface constitute supporting surface to circuit board, the supporting surface formed in circuit board is placed on two stripe board, cylinder opens
Dynamic so that circuit board upper surface contacts with web plate, starts simultaneously at the components and parts attachment part to circuit board upper surface and carries out tin cream
Brush；Wherein, multiple dividing plates are evenly distributed on base plate so that the uniform force of each local on the lower surface of circuit board, especially
Being the abundant stress in middle part of circuit board, when circuit board contacts with web plate, the middle part of circuit board does not haves and subsides or recessed
Etc. situation, and then make the tin cream thickness distribution when brushing uniform, it is to avoid the tin cream thickness in the middle part of circuit board is too high and causes
There is component's feet short circuit in circuit board when using after attachment completes, substantially increase the crudy of circuit board.Further, root
Dimension and shape according to circuit board is different, can increase and decrease the dividing plate number between two stripe board at any time, to ensure that circuit board exists
Stable support during brush cream.Further, after circuit board contacts with web plate and when proceeding by brush cream, owing to not having on dividing plate
Circuit board is fastened by clamping device so that skew occurs when brush cream in circuit board, then causes the tin cream on circuit board to be coated with
The station of brush is forbidden, and inventor has multiple pore below base plate, and connection has flexible pipe, flexible pipe and air pump in the lower section of pore
Connect, i.e. in base plate uphill process, in the most airtight interval formed between two adjacent dividing plates, produced by air pump
Raw suction makes to produce below circuit board a negative pressure so that the negative pressuren zone corresponding to circuit board produces suction to circuit board, i.e.
Can guarantee that circuit board is stably fixed in dividing plate and stripe board, to avoid circuit board to produce skew, Jin Erti when brush cream
The brush cream quality of high circuit board.
The upper surface of described stripe board flushes with the upper surface of described dividing plate.As preferably, the upper surface of stripe board with every
The upper surface of plate flushes so that the contact area between the lower surface of circuit board and dividing plate and the new plate of bar increases, and then realizes
Improve the stability of strutting system of circuit board.
The adjacent spacing between two draw-in grooves is 2 ~ 8.As preferably, the spacing between two draw-in grooves is at 2 ~ 8 models
In enclosing, the spacing between i.e. two dividing plates is also in 2 ~ 8 scopes, according to thickness, the hardness size of various boards, and 2 ~ 8
Spacing can be suitable for the overwhelming majority models circuit board so that the range of the present invention is greatly enhanced.
Described dividing plate is PVC board.As preferably, select PVC material to make dividing plate, ensureing that dividing plate possesses certain support
On the premise of intensity, moreover it is possible to when circuit board contacts with web plate and during brush cream, produce trace deformation with by suffered by circuit board
Applied stress eliminate, reduce circuit board loss percentage.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, multiple dividing plates of the present invention are evenly distributed on base plate so that the uniform force of each local on the lower surface of circuit board,
The particularly abundant stress in the middle part of circuit board, when circuit board contacts with web plate, the middle part of circuit board do not have subside or
The situation such as recessed, and then make the tin cream thickness distribution when brushing uniform, it is to avoid the tin cream thickness in the middle part of circuit board too high and
Cause circuit board that component's feet short circuit occurs when using after attachment completes, substantially increase the crudy of circuit board.And
And, the dimension and shape according to circuit board is different, can increase and decrease the dividing plate number between two stripe board at any time, to ensure circuit
The plate stable support when brush cream；
2, in the present invention, the upper surface of stripe board flushes with the upper surface of dividing plate so that the lower surface of circuit board and dividing plate and bar
Contact area between new plate increases, and then realizes improving the stability of strutting system of circuit board.
