Abstract

The present invention relates to a drop-off table device for an optical lens production mold. The device includes four parts: an upper mold, a lower mold, an outer mold sleeve and a drop-off table. The drop-off table device sucks the upper mold through a vacuum suction cup (4), and The vertical movement of the double linear T-shaped guide posts (16) realizes the opening and closing action flow of the upper and lower molds of the optical lens mold. The completion of this action requires manual operation. Fix the optical lens mold on the bottom stage (5) of the fall-off table, and manually press the upper plate (3) through the handle (1), so that the vacuum suction cup (4) attracts the upper plate (3). The mold is then lifted up slowly. With the help of the load and the force of the spring, the upper board (3) is raised to the top. First, take out the optical lens that has been hot-pressed, and then put the blank into the mold and press down through the handle. The upper layer board (3) makes the upper mold successfully fit into the mold sleeve to complete an action process. Then it is only necessary to send the closed mold to the subsequent assembly line for hot pressing. The invention is simple to operate, meets the requirements for high precision of the equipment, and has strong durability.

Background technique

The present either large area universalness of the electronic equipments such as mobile phone, computer or the high-precision medical treatment of medical industry is set Standby development, people are more and more for the demand of high-precision optical camera lens, especially the fast development of smart phone in recent years, People are higher and higher for the temperature taken pictures, and more and more double even three shooter's machines of taking the photograph start to popularize in the market, this undoubtedly increases Demand of the market to optical lens is added.But currently on the market fall off platform operation it is excessively cumbersome, it cannot be guaranteed that camera lens and The precision of mold, poor durability.

Summary of the invention

The present invention provides that a kind of durability is good, structure is simple, optical frames easy to use according to the deficiency of the above technology Head mold falls off platform.

The invention is realized by the following technical scheme:

A kind of optical lens mould falls off platform.Including upper die and lower die, outer die casing and four part of platform that falls off, the platform equipment that falls off by The groups such as pedestal, linear guide poles, vacuum chuck, top plate, handle, damper, caging bolt, weight bearing, positioning curved bar, buffering pulley At.Wherein vacuum chuck can external vacuum pump realize its adsorption function.

Compared with prior art, a kind of the fall off beneficial effect of platform of optical lens mould of the present invention is mainly shown as:

1, the vertical straight line movement that bilinear guide post is realized, positioning accuracy is high, and durability is strong, and double guide posts are using industry Standard component, replacement are convenient.

2, it being manually completed during pushing by worker, movement is simple, and it is easy to operate, additional training is not necessarily to worker It uses.

3, design has adjustable counterweight, can realize letter using the individual instances of abrasion condition and worker according to equipment Drag size during dullness section pushing, it is more humanized.

4, design has adjustable caging bolt, and the height of Bottom Of Descent can be adjusted according to the mold of different height, Realize the suitability of multiple kinds of molds.

5, in Bottom Of Descent position, design has damping buffer unit, and can preventing worker, operationally laminate decrease speed is too fast And damage blank material.

6, design has positioning curved bar, can increase service life, to prevent equipment from positioning after reaching certain service life Error is excessive to be led to not normally mold.

7, being used cooperatively for curved bar curved boom and cushion idler is positioned, the work for playing buffering during top plate decline can be made With, prevent damage blank material.

8, the present invention is that a kind of design is reasonable, is skillfully constructed, is practical, being easy to the optical lens that factory mass uses Mould falls off platform.

Specific embodiment

With reference to the accompanying drawing in detail narration the embodiment of the present invention, it should be noted that the present embodiment be it is narrative, no It is restrictive, this does not limit the scope of protection of the present invention.

As shown in Figure 1 and Figure 2, the present invention is that a kind of optical lens mould falls off platform, and composition includes that handle 1, cushion idler are fixed Frame 2, top plate 3, vacuum chuck 4, bottom surface objective table 5, pedestal 6, positioning curved bar 7, linear guide 8, slidably limit for height platform 9, can It adjusts limit for height bolt 10, damper 11, ball sleeve 12, shell 13, pulley 14, wirerope 15, T-type guide post 16, outer bush 17, hold Holding arms 18, adjustable pouring weight 19, cushion idler 20, anchor and connector are well-known technique, therefore are no longer repeated.

Implementation about the platform that falls off: cushion idler fixed frame 2, cushion idler 20, positioning curved bar 7, linear guide 8 it Between cooperation the positioning action during the decline of top plate 3 may be implemented, and can produce a damping force and make its decline There is a buffer function in the process.With the use of working efficiency can be improved, durability is strong for vacuum chuck 4, bottom surface objective table 5. Adjustable pouring weight 19 can be adjusted according to the concrete condition of distinct device, and itself service condition of different workers with great It is small.The specific structure of each section and mutual specific connection relationship are described in detail below: handle 1 and handle arm 18 One end is connected by bolt, and the other end of handle arm 18 is fixed on above top plate 3, can be realized by pushing with pull-up handle The decline and lifting process of top plate 3.

Top plate 3 is connect with 2 outer bush 17 above, and outer bush 17, ball sleeve 12 and T-type guide post are ball guide post Pair, T-type guide post low side are connected with pedestal.Connecting steel wire ropes 15, wirerope 15 pass through the guiding of two pulleys to top plate 3 above Effect, the other end connect adjustable pouring weight 19, and adjustable pouring weight 19 plays the role of a resistance to the decline of top plate 3, When worker does not operate, counterweight can make top plate be always positioned at eminence.

Top plate 3 fixes vacuum chuck 4, and the external vacuum pump of vacuum chuck 4 can attract the upper mold of optical lens mould.On 3 two sides of laminate secure two cushion idler fixed frames 2, cushion idler fixed frame 2 and are connected with cushion idler 20 by linear guide 8 It connects, the sliding rail of linear guide 8 is fixed on above cushion idler fixed frame 2, and cooperation positioning curved bar 7 is during top plate 3 declines Positioning action and buffer function may be implemented.

Slidably limit for height platform 9 and adjustable limit for height bolt 10 decline height with the use of top plate 3 may be implemented to pedestal 6 above Position position-limiting action is spent, the effect of one deceleration buffer when reaching spacing place of top plate 3, Ke Yibao may be implemented in damper 11 Protect the damage of blank material.
