Abstract
The utility model relates to an improving method of a dolly of a warped board flatness-arranging machine used in printed circuit board (hereinafter referred to as PCB for short) industry. The dolly is suitable for a warped board flatness-arranging process of an unformed large-board workpiece. The dolly comprises an upper pressing plate, a lower pressing plate, a handle, an elevating device, a roller disc, and lower idler wheels. The upper pressing plate and the lower pressing plate are connected with each other through the elevating device. The upper pressing plate is fixed on the middle part of the handle, while the lower pressing plate is fixed on the bottom of the handle. A plurality of rollers arranged in parallel are disposed in the roller disc mounted on the upper pressing plate. The four lower idler wheels are arranged on the four corners of the lower pressing plate. A cooperating dolly is designed for a pressing disc. Material is directly transmitted by the rollers and laminated plate transmitting mode is optimized. A process of one-by-one laminated plate transmission is replaced by a process of dolly transmission, so that labor intensity is substantially reduced and effective productive capability of the flatness-arranging machine is increased.
Description
Technical field
The utility model relates to Printed circuit board(hereinafter to be referred as PCB) method of modifying of the dolly of the warping anti-stetch machine used of industry, carry out plate and stick up anti-straight operation to be fit to large 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, such as boring, electroplate outer-layer circuit, the operations such as anti-welding baking, the PCB workpiece is because the mechanical external force that is subject in the processing procedure affects, planarization variation, particularly plate thickness are less than the workpiece of 1mm, and the impact that is subject to is more obvious, generally speaking in order to satisfy the shipment specification requirement of client's plate prying, be chosen in the visual inspection operation and carry 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 such as compact dimensions, workpiece is jumped out fixing pin and is dragged for the situation of scrapping and occur 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 large 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, and the anti-directly machine that present stage uses also designs and produces according to the anti-straight operation requirements of large plate prying, is suitable for moulding platelet afterwards anti-straight.Use this equipment to carry out large plate anti-straight the time, exist and remove plate inconvenience, the problem that labour intensity is large.
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, only have both hands one little folded one little folded several times plate being sent to of depending on the operator to press the storehouse, then shut after folded expiring and press the storehouse to carry out anti-straight operation.Not only manipulation strength is large, also often can cause lamination on the irregular anti-straight effect of pressing plate that affects.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, a kind of dolly of the straight machine of reflex action of process repacking is provided, it can optimize the lamination feeding style, the artificial one by one process of lamination feeding is become the process of car load feeding, greatly reduce labour intensity, guaranteed simultaneously anti-straight effect.
According to the technical scheme that the utility model provides, the dolly of warping anti-stetch machine comprises top board, lower platen, handle and lowering or hoisting gear; Connect by 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; Described 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.
Described lowering or hoisting gear is comprised of connecting rod, lower link and pin rod on four groups, and upper connecting rod and lower link are fixed its relative position by pin rod, and upper connecting rod one end and top board are fixed, and lower link one end and lower platen are fixed.
The utlity model has following advantage: the utility model is for the dolly of a kind of cooperation of design of platens, by the direct feeding of roller bearing, can optimize the lamination feeding style, the artificial one by one process of lamination feeding is become 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 by 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; Described 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.
Described lowering or hoisting gear 4 is comprised of connecting rod 9, lower link 10 and pin rod 8 on four groups, and upper connecting rod 9 and lower link 10 are fixed its relative position by pin rod 8, and upper connecting rod 9 one ends and top board 1 are fixing, and lower link 10 1 ends are fixed with lower platen 2.
When carrying out the anti-straight process operations of plate prying, first 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 that the workpiece of folding is shifted onto anti-straight machine front, to good position, directly advance and press the storehouse, use the locking pin that workpiece is blocked after putting in place and prevent landing.Fill process finishes like this.According to the program that sets, first heating leveling enters cooling again, until termination routine, small handcart takes down the locking pin to connecting, and workpiece is released anti-straight machine press the storehouse, falls and carries out discharging above the small handcart.
