Abstract

The invention relates to an automatic limiting lifting platform. Materials are placed on the limiting lifting platform and limited to work stations. The lifting platform comprises a lower work table and an upper work table over the lower work table, wherein the materials are placed on the lower work table, a pair of height sensors are arranged outside the diagonal of the lower work table, and the height sensors interact with each other, monitor the height of the materials and limit the materials to the work stations. According to the automatic limiting lifting platform, the pair of height sensors automatically monitor the height of the materials, the monitored height is accurate, an auxiliary buffer device is designed, and automatic limiting and automatic lifting adjustment are achieved. The device is simple in structure, easy to operate, high in practicability and good in implementation effect.

Description

A kind of automatic spacing bay-lift

Technical field

The present invention relates to a kind of automatic spacing bay-lift, be used for accurately controlling the working position height of bay-lift, belong to printed circuit board (PCB) processing technique field.

Background technology

In printed circuit board (PCB) processing technique field, need to the prepreg of oven dry and copper-clad plate etc. be carried out superimposed compressing.In superimposed operation, need the strict height of controlling working position.In existing superimposed operation, highly control inaccuracy, cannot meet technical requirements.

Summary of the invention

The deficiency that the present invention exists for prior art just, provides a kind of automatic spacing bay-lift.

For addressing the above problem, the technical solution used in the present invention is as follows:

A kind of automatic spacing bay-lift, material is placed on bay-lift and is limited on working position, described bay-lift comprises lower table, and the upper table directly over it, material is placed on lower table, on lower table diagonal line outside, a pair of height sensor is set, height sensor interacts and monitors the height of material, and is limited on working position.

As the improvement of technique scheme, on described lower table, be provided with a plurality of transmission shafts, on transmission axle, be provided with transfer roller, transfer roller is staggered to be uniformly distributed.

As the improvement of technique scheme, at lower table, near operating surface one side, be provided with bump rubber, near being provided with between the adjacent transmission shaft of bump rubber one side, there is certain elastomeric damper.

As the improvement of technique scheme, on described upper table, be provided with a plurality of suction Palestine and Israels and stop block, inhale bar absorption carrying material, the height of bar carrying material is inhaled in stop block restriction.

Compared with prior art, implementation result of the present invention is as follows in the present invention:

Automatic spacing bay-lift of the present invention, utilizes a pair of height sensor automatically to monitor the height of material, and its monitoring is highly accurate, and is designed with auxiliary buffering device, realizes automatic spacing and automatically regulates lifting.This apparatus structure is simple, simple to operate, practical, and implementation result is good.

The specific embodiment

Content of the present invention is described below in conjunction with specific embodiments.

As shown in Figure 1, be automatic spacing bay-lift structural representation of the present invention, Fig. 2 is A-A view in Fig. 1.Automatic spacing bay-lift of the present invention, comprises lower table 10, and the upper table directly over it 20.On lower table 10, be provided with a plurality of transmission shafts 11, be provided with transfer roller 12 on transmission axle 11, transfer roller 12 is staggered to be uniformly distributed.

At lower table 10, near operating surface one side (be in Fig. 2 bottom), be provided with bump rubber 14, near being provided with between the adjacent transmission shaft 11 of bump rubber 14 1 sides, there is certain elastomeric damper 13.On lower table 10 diagonal line outsides, a pair of height sensor 15 is also set, height sensor 15 interacts and monitors the height of placing material 30 on lower table 10.The plane of Liang Ge lower floor material 31 corresponding formation is the working position (in Fig. 1 shown in dotted line) of bench board 10.When the height of material 30 is during higher than working position, built-in system circuit switches, and drives lower table 10 to move downward, until material 30 upper ends, on working position, like this, are placed on material 30 lower table 10 and are limited on working position.

On upper table 20, be provided with a plurality of suction bar 21 and stop block 22.Inhale bar 21 and be communicated with outer inside casing (not shown), utilize cylinder to produce negative pressure and can, with inhaling bar 21 absorption materials 30, realize like this object of carrying material 30.Stop block 22 has limited inhales 21 height that can carry material 30 of bar, upper table 20 is played to the effect of protection.

As shown in Figure 3, structural representation during for automatic spacing bay-lift work of the present invention, Fig. 4 is B-B view in Fig. 3.Placement of multiple layers material 30 on the lower table 10 of bay-lift, material 30 comprises lower floor's material 31 and upper materials 32.In order more clearly to describe each details, in Fig. 4, with dotted line, identify the position of material 30.

When lower floor's material 31 is sent to operating surface (be in Fig. 4 bottom) by transmission shaft 11 and transfer roller 12, at the Xia，Jiang lower floor material 31 that stops of bump rubber 14, stop.But bump rubber 14 is still given the antagonistic force of 31 1 bufferings of lower floor's material, for fear of lower floor's material 31, leave bump rubber 14, near being provided with between the adjacent transmission shaft 11 of bump rubber 14 1 sides, have certain elastomeric damper 13, damper 13 has prevented the counter motion of lower floor's material 31.Now, height sensor 15 monitors lower floor's material 31 height higher than working position, and built-in system circuit switches, drive lower table 10 to move downward, until the top of lower floor's material 31 is on working position, ，Jiang lower floor material 31 is placed on lower table 10 and is limited on working position like this.

Now, inhale bar 21 again by upper materials 32 absorption carryings, and be placed on lower floor's material 31, height sensor 15 monitors again upper materials 32 height higher than working position, built-in system circuit switches again, drive lower table 10 to continue to move downward, until the top of upper materials 32 is on working position.

Like this, by the monitoring of height sensor 15, can all the time material 30 be controlled on working position, meet the requirement to height in superimposed operation.
