Abstract
The invention relates to an improvement method for a trolley of a warped board straightening machine in the printed circuit board (PCB) industry. The improvement method is suitable for the warped board straightening of unformed large board workpieces. The trolley comprises an upper pressure plate, a lower pressure plate, a handle and a lifting device, wherein the upper and lower pressure plates are connected through the lifting device; the upper pressure plate is fixed on the middle part of the handle; and the lower pressure plate is fixed at the lower end of the handle. The trolley also comprises a rolling shaft plate and lower rollers, wherein the rolling shaft plate is arranged on the upper pressure plate; a plurality of rolling shafts are arranged in parallel in the rolling shaft plate; and four lower rollers are positioned on the four corners of the lower pressure plate. The trolley is matched with a platen, materials are directly fed through the rolling shafts to optimize a board stacking feeding mode, and the process of manually stacking boards one by one for feeding is replaced by an entire feeding process, so that labor intensity is greatly reduced, and the effective yield of the straightening machine is improved.
Description
Technical field
The present invention relates to the method for modifying of the dolly of the warping anti-stetch machine that Printed circuit board (hereinafter to be referred as PCB) industry uses, carry out plate and stick up anti-straight operation to be fit to big plate workpiece before the moulding.
Background technology
The PCB workpiece is after being pressed into semi-finished product, and planarization is very good, but follow-uply also will pass through a lot of procedures, like boring; Electroplate outer-layer circuit, operations such as anti-welding baking; The PCB workpiece is because receive the mechanical external force influence in the processing procedure, and planarization variation, particularly plate thickness are less than the workpiece of 1mm; The influence that receives is more obvious, generally speaking in order to satisfy the shipment specification requirement of client's plate prying, is chosen in the visual inspection operation and carries out plate and stick up anti-straight.
If but carry out processing and forming like this; Can bring a lot of negative consequences to procedure for processing, bad like compact dimensions, workpiece jumps out fixedly that pin drags for the situation appearance of scrapping in the course of processing; Also can cause electrical measurement operation false failure rate high; So occur for fear of above-mentioned situation, before processing and forming, require big plate to carry out the anti-straight of plate prying, so also can improve the operating efficiency that pressing plate sticks up.
In the PCB industry, the anti-straight work of plate prying is generally all carried out at the FINAL APPEARANCE inspection process, present stage the anti-straight machine that uses also anti-straight operation requires to design and produce according to big plate prying, the platelet that is suitable for after the moulding is anti-straight.It is anti-straight the time to use this equipment to carry out big plate, exists and removes plate inconvenience, the problem that labour intensity is big.
Be in particular in the process in workpiece feeding entrance pressure storehouse; At first, open and press the storehouse, because height finite sum platen does not have roller design; Have only by operator's both hands one little folded one little folded sending plate to several times and press the storehouse, close then after folded expiring and press the storehouse to carry out anti-straight operation.Not only manipulation strength is big, also causes lamination to the irregular anti-straight effect of pressing plate that influences through regular meeting.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point; A kind of dolly of the straight machine of reflex action of process repacking is provided, and it can optimize the lamination feeding style, becomes the process of artificial a slice a slice lamination feeding the process of car load feeding; Greatly reduce labour intensity, guaranteed anti-straight effect simultaneously.
According to technical scheme provided by the invention, the dolly of warping anti-stetch machine comprises top board, lower platen, handle and lowering or hoisting gear; Connect through lowering or hoisting gear between top board and the lower platen, lower platen is fixed in the handle lower end; Also comprise roller bearing dish and bottom roller; Said roller bearing dish is installed on the top board, is provided with the some roller bearings that are arranged in parallel in the roller bearing dish; Four bottom rollers are positioned on four angles of lower platen.
Said lowering or hoisting gear is made up of connecting rod, lower link and pin rod on four groups, and last connecting rod and lower link are through fixing its relative position of pin rod, and last connecting rod one end and top board are fixed, and lower link one end and lower platen are fixed.
The present invention has following advantage: the dolly that the present invention is directed to a kind of cooperation of design of platens; Through the direct feeding of roller bearing, can optimize the lamination feeding style, become the process of artificial a slice a slice lamination feeding the process of car load feeding; Greatly reduce labour intensity, improved anti-straight machine effective capacity.

Embodiment
As shown in Figure 1, the dolly of warping anti-stetch machine comprises top board 1, lower platen 2, handle 3 and lowering or hoisting gear 4; Connect through lowering or hoisting gear 4 between top board 1 and the lower platen 2, lower platen 2 is fixed in handle 3 lower ends; Also comprise roller bearing dish 5 and bottom roller 6; Said roller bearing dish 5 is installed on the top board 1, is provided with the some roller bearings that are arranged in parallel 7 in the roller bearing dish 5; Four bottom rollers 6 are positioned on four angles of lower platen 2.
Said lowering or hoisting gear 4 is made up of connecting rod 9, lower link 10 and pin rod 8 on four groups, and last connecting rod 9 and lower link 10 are through pin rod 8 fixing its relative positions, and last connecting rod 9 one ends are fixed with top board 1, and lower link 10 1 ends and lower platen 2 are fixed.
When carrying out the anti-straight process operations of plate prying, earlier at the anti-straight good small handcart of machine outside fix, then PCB workpiece a slice plate as requested; A slice brown paper is apart from one another by neatly being stacked on above the small handcart; Be laminated to after the satisfactory height, use small handcart to shift the workpiece of folding onto anti-straight machine front, good position; Directly advance and press the storehouse, use the locking pin to block workpiece after putting in place and prevent landing.Fill process finishes like this.According to the program that configures, heating leveling earlier gets into cooling again, and until termination routine, small handcart takes down the locking pin to connecting, and releases anti-straight machine to workpiece and presses the storehouse, falls and carries out discharging above the small handcart.
