Embodiment
Below embodiment of the present utility model is described in detail:
As Figure 1-3, a kind of aeroscopic plate for wire mark welding resistance consent, is positioned at immediately below pcb board (accompanying drawing does not identify).Described aeroscopic plate comprises substrate 100, suction filtration system 500 and multiple air guide piston 300.Be provided with the container cavity 110 be communicated with suction filtration system 500 in substrate 100, substrate 100 is provided with the multiple gas ports 120 be communicated with container cavity 110 towards pcb board side.Air guide piston 300 and gas port 120 one_to_one corresponding.Multiple air guide piston 300 include can the first main body 310, first main body 310 of telescopic moving up and down through gas port 120.As shown in Figure 2, in its natural state, the sidewall close contact of the first main body 310 and gas port 120.When pcb board consent, consent scraper (accompanying drawing does not identify) above it mobile extruding air guide piston 300, air guide piston 300 power that is squeezed is sunk, again because the width of the first main body 310 from top to bottom increases gradually, when the first main body 310 is sunk will and gas port 120 between form space 121, as shown in Figure 3.The ink of consent scraper extruding will be extracted in rear quick injection pcb board via hole by space 121 by suction filtration system 500, improve consent quality, reduce consent number of times.When consent scraper away from time, air guide piston 300 rises and resets, and is sealed by gas port 120, ink can be avoided in this position via hole to continue to be taken away by vacuum, thoroughly prevents this upper end, position from occurring cavitation.The utility model, by the mode of vacuum filtration, has speeded solder mask consent flow velocity, improves consent plumpness and a consent qualification rate, effectively improves welding resistance consent quality, and structure is simple, reasonable in design.
As shown in Figure 2, in the present embodiment, the first main body 310 is provided with arc sections 311 near pcb board one end, and point cantact between arc sections 311 and pcb board prevents contact area excessive, blocking via hole.The PVC material that first main body 310 and arc sections 311 are suitable for by hardness forms, and avoids scratch pcb board face.
As shown in Figure 3-4, air guide piston 300 also comprises the second main body 320 of support first main body 310, second main body 320 is positioned at container cavity 110, and the second main body 320 is made up of elastomeric material, and thus when air guide piston 300 is under pressure, the second main body 320 is compressed drive first main body 310 and sunk.When extruding force disappears, the second main body 320 drives the first main body 310 to automatically reset, and achieves the telescopic moving up and down of air guide piston 300.
The width that second main body 320 comprises the first supporting seat 321 and the second supporting seat 322, first supporting seat 321 connected successively up and down from top to bottom reduces gradually, and the width of the second supporting seat 322 from top to bottom increases gradually.Above-mentioned design makes the width of the second main body 320 first reduce from top to bottom to increase afterwards, reaches minimum at its width of middle part of the second main body 320.Because the second main body 320 is elastic component, elastic component will expand while being under pressure, and wherein middle part expansion amplitude is maximum.Second main body 320 is designed to the narrower structure in middle part, prevents position, intermediate portion from expanding excessive because of elastic deformation, causes contacting with adjacent air guide piston 300, blocking suction filtration passage.
Second main body 320 is provided with through hole 323, and through hole 323 is positioned at the junction of the first supporting seat 321 and the second supporting seat 322.On the one hand being provided with of through hole 323 is beneficial to the second main body 320 and is squeezed force deformation, reduces the thickness of the second main body 320 middle part on the other hand, prevent the second main body 320 due to the power expansion deformation that is squeezed excessive.
As Figure 1-3, the utility model also comprises the cell body 200 be positioned at below substrate 100, and cell body 200 is connected with substrate 100.The bottom of container cavity 110 is provided with and the multiple liquid flow holes 111 be communicated with in cell body 200, is provided with the aeroscopic plate scraper plate 210 that can move left and right in cell body 200.Instantly when oil mass is excessive, ink enters after container cavity 110 and cell body 200 through gas port 120, clears up the ink in cell body 200 by mobile aeroscopic plate scraper plate 210, prevents ink from blocking gas port 120.Meanwhile, avoid the tedious work of frequent clean, improve consent efficiency.
As shown in Figure 1, in the present embodiment, suction filtration system 500 comprises and the ink collection tank 510 be communicated with in cell body 200 and the pump housing 520 be communicated with ink collection tank 510.Aeroscopic plate scraper plate 210 in cell body 200 can drive ink to enter ink collection tank 510 to carry out ink recycling.
The utility model also comprises the cover plate 400 that can move left and right, and cover plate 400 is positioned at above air guide piston 300, for regulating the sealing range of aeroscopic plate.When pcb board size is less, by cover plate 400, the part air guide piston 300 without the need to using is sealed, preventing dust in air etc. from entering in aeroscopic plate and blocking gas port 120.Thus the applicable different size pcb board of the utility model carries out consent, facilitates demonstration plant's production operation.In the present embodiment, cover plate 400 is symmetrically arranged two, the convenient sealing range simultaneously regulating aeroscopic plate from two ends.
Cover plate 400 is made up of flexible sealing material, and cover plate 400 volume is located on rotation axis 410.One of them end of rotation axis 410 is also provided with the knob 420 for driving rotation axis 410 to rotate.When needs cover air guide piston 300, can manually pull out cover plate 400; When the pcb board consent of large-size must be applicable to, drives rotation axis 410 to rotate by knob 420, cover plate 400 is furled, to adapt to pcb board size.Cover plate 400 described in the utility model can move left and right and also can be designed to according to actual needs be slidably matched between cover plate 400 and aeroscopic plate, and the cover plate 400 of pre-designed suitable length, regulates different sealing ranges by slide cover 400.
In sum, the utility model optimizes wire mark welding resistance jack process, effectively improves consent quality.When consent scraper drives ink to carry out consent, air guide piston 300 can respond to scraper pressure, air guide piston 300 is at jack position zones open, keep sealing in non-jack position region, realize jack position local vacuum-pumping, avoid being mixed with bubble in ink, accelerate rabbet ink filling speed, ensure that a cutter fills up, avoid repeatedly entrained air bubbles in consent, reduce solidification oil spilling phenomenon.The utility model is reasonable in design, and structure is simple, and cost of manufacture is cheap.
Each technical characteristic of above embodiment can combine arbitrarily, for making description succinct, all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification is recorded.
Above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
