Problems solved by technology

At present, the flexible circuit board pressing devices used in the market are generally designed in the way of clamping the upper and lower boards to realize the pressing. Each pressing device can only press one version of the product at a time, and the efficiency is low; in addition, ordinary flat pressing It is difficult to ensure the reinforcing effect of some areas on the circuit board, and the pressing effect is poor; in addition, the ordinary multi-layer pressing device is generally reset by the self-resetting of the middle pressing plate, but it is reset after the actual pressing operation In the first stage, the middle platen is easily adsorbed on the upper plate for a short time. At this time, the lower plate usually continues to go down through the hydraulic cylinder. When the operator sees the separation between the lower plate and the middle platen, he may reach out to take the lower plate by mistake. For the products above, due to the heavy weight of the middle pressure plate, the middle pressure plate may drop suddenly and cause hand pressing accidents, and the safety is extremely poor

Embodiment 1

[0025] Embodiment 1: as Figure 1 to Figure 3 As shown, the present invention includes a casing 1, two sets of pressing assemblies arranged symmetrically on both sides of the casing 1, each set of pressing assemblies includes an upper fixing plate 2, a middle plate 3 and a lower pressing plate 4, Both the inside of the upper fixing plate 2 and the inside of the middle plate 3 are provided with vacuum chambers, and the lower surface of the upper fixing plate 2 and the lower surface of the middle plate 3 are provided with corresponding vacuum chambers. The airbag cavity is connected with an elastic sealing pressure film, and the casing 1 is provided with a position-limiting module 5 matched with the middle plate 3 in the middle. In the present invention, the middle plate 3 divides the pressing area between the upper fixing plate 2 and the lower pressing plate 4 into two, and the present invention has two sets of pressing assemblies, thus forming a four-opening structure, which c...

Embodiment approach

[0028]A hook device 10 is provided on the outer side of the lower platen 4, and the hook device 10 includes a rotating hook block 11 and a fixed path guide column 12, and a hook point 13 is provided on the side of the middle plate 3 , the rotating shaft 111 of the rotating hook block 11 is arranged on the side of the lower platen 4, the surface of the rotating hook block 11 is provided with a path through groove 14 matching with the path guide column 12, and the path The guide post 12 is inserted into the path through groove 14, and the path through groove 14 includes a section of inner turn structure 15, and the path guide post 12 is guided at the inner turn structure 15 during the upward movement of the lower pressing plate 4. The rotating hook block 11 rotates inwards so that the rotating hook block 11 hooks the hook point 13 . In the present invention, the hook device 10 is used to pull down the middle plate 3 through the hook point 13 when the lower platen 4 goes down, so...

Embodiment 2

[0034] Embodiment 2: Different from Embodiment 1, the upper fixing plate 2 is fixedly arranged on the upper end surface of the cavity 19, and both sides of the middle plate 3 are provided with The card position bump. The clamping projection plays the role of contacting and going up the buffer frame 20, which is similar to the effect of the limit projection 7; the middle plate 3 contacts the buffer frame 20 and is integrated with the buffer frame 20. The gaps between the shells 1 provide buffer spaces.

[0035] The invention can be used in the technical field of fast presses.

Abstract

The invention discloses and provides an FPC four-opening vacuum air bag rapid pressing machine with simple structure, high efficiency, good effect and high safety. The technical solution adopted in the present invention is: the present invention includes a casing, two sets of pressing components arranged symmetrically on both sides of the casing, and each set of pressing components includes an upper fixing plate, a middle plate and a lower pressing plate , the inside of the upper fixing plate and the inside of the middle plate are provided with vacuum air pockets, and the lower surface of the upper fixing plate and the lower surface of the middle plate are provided with vacuum air pockets corresponding to the corresponding vacuum air pockets. The matching elastic sealing pressure film is connected, and the middle part of the casing is provided with a limit module matched with the middle plate. The invention can be used in the technical field of fast presses.

Description

technical field [0001] The invention relates to a fast pressing machine for FPC four-opening vacuum air bags. Background technique [0002] Flexible circuit boards (also known as FPC or flexible printed circuit boards) generally adopt the form of multi-layers, and the layers are pressed together by a special pressing device to form a multi-layer flexible circuit board. At present, the flexible circuit board pressing devices used in the market are generally designed in the way of clamping the upper and lower boards to realize the pressing. Each pressing device can only press one version of the product at a time, and the efficiency is low; in addition, ordinary flat pressing It is difficult to ensure the reinforcing effect of some areas on the circuit board, and the pressing effect is poor; in addition, the ordinary multi-layer pressing device is generally reset by the self-resetting of the middle pressing plate, but it is reset after the actual pressing operation In the firs...
