Detailed Description

Referring to fig. 1, 9-11, the utility model provides a full-automatic tear-open press from both sides machine, including the frame, work platform 3's the left and right sides sets up one respectively and tears open and press from both sides device 4, and work platform 3's rear side sets up categorised storage device 8, and work platform 3, tear open and press from both sides device 4 and categorised storage device 8 all install in the frame certainly.

The frame and the printed circuit board are relatively fixed through the clamp, so that the circuit board is integrally formed. The utility model aims at automatically disassembling the clamp on the circuit board and separating the frame from the printed circuit board and respectively automatically storing the frame and the printed circuit board.

When the circuit board sorting device is used, the circuit board is usually placed on the working platform manually or automatically (the state of the circuit board is that the frame is positioned on the upper side of the printed circuit board at the moment), then the clamp dismounting device works to dismount the clamps on the left side and the right side of the circuit board respectively, and then the sorting device is used for respectively storing the frame and the printed circuit board.

The following describes specific mechanisms of the clip detaching device and the sorting and storing device.

Regarding the clip removal device:

referring to fig. 9-13, the unclamping device 4 includes a mounting platform 41, a second air cylinder 42 and a first slide rail 43, first, a plurality of unclamping jaws 1 are mounted on the mounting platform 41, the unclamping jaws 1 are arranged on the mounting platform 41 in a front-back direction, the first slide rail 43 is in a left-right direction, the mounting platform 41 is mounted on the first slide rail 43, the mounting platform 41 can slide in the left-right direction, a free end of a piston rod of the second air cylinder 42 is connected with the mounting platform 41, and the mounting platform 41 is pushed by the second air cylinder 42 to move on the first slide rail 43.

Taking the unclamping device 4 on the left side of the working platform 3 as an example, the process of unclamping is explained:

the circuit board is positioned on the working platform 3, the second air cylinder 42 pushes the mounting platform 41 to move rightwards along the first slide rail 43, when the mounting platform 41 reaches the rightmost side, the dismounting clamping jaws 1 on the mounting platform 41 just correspond to the clips on the circuit board, and the clips are clamped by the dismounting clamping jaws 1; then, the second cylinder 42 works to drag the mounting platform 41 leftwards, so that the dismounting clamping jaw 1 is dragged leftwards, the purpose of dismounting the clamp is realized, the dismounting clamping jaw 1 is opened, and the clamp automatically drops from the dismounting clamping jaw 1.

It should be emphasized that the unclamping device 4 on the left side and the unclamping device 4 on the right side of the working platform 3 work simultaneously, so that the clamps on the left and right sides of the circuit board are dismounted simultaneously, and the stress balance of the circuit board in the unclamping process is relatively ensured.

In addition, the dismounting claws 1 on the mounting platform 41 are detachable, a specific number of dismounting claws 1 can be mounted on the mounting platform 41 according to actual conditions (the number of the dismounting claws 1 corresponds to the number of the clips 2 on one side of the circuit board), and meanwhile, the front and back positions of the dismounting claws 1 on the mounting platform 41 can be adjusted, so that each dismounting claw 1 can exactly correspond to the position of one clip 2 to be dismounted. Specifically, the method comprises the following steps: the installation platform 41 can be provided with a slideway, the dismounting clamping jaw 1 is fixed on the slideway, the front and back positions of the dismounting clamping jaw 1 can be adjusted by sliding the dismounting clamping jaw 1 on the slideway, and after the dismounting clamping jaw 1 is adjusted to a proper position, the dismounting clamping jaw 1 can be relatively fixed on the installation platform 41 by a locking mechanism (such as a mode of locking a bolt).

The inventor considers, under the practical application condition, at the split clamp in-process, split clamping jaw 1 and be grabbing the clip, when dragging clip 2, probably can drag the circuit board, can not change with work platform 3 relative position all the time for guaranteeing this in-process circuit board, the utility model discloses still make following improvement:

referring to fig. 12, each special unclamping system further includes an auxiliary platform 44, the second cylinder 42 and the first slide rail 43 are relatively fixed on the auxiliary platform 44, and the pressing plate device 5 is disposed on the auxiliary platform 44.

The main functions of the platen device 5 are: when the clamp is disassembled, the pressing plate on the pressing plate device 5 can be pressed downwards to press the printed circuit board and the frame, so that the circuit board cannot be displaced, and the pressing plate is lifted up after the clamp is separated from the circuit board.

To achieve the above object, the platen device 5 may adopt one of the following two ways.

First platen device 5:

referring to fig. 14 and 15, the pressing plate device 5 includes a pressing plate cylinder 51, a pressing plate 53, a connecting rod 52 and a supporting rod 54, the pressing plate cylinder 51 is vertically disposed (a piston rod of the pressing plate cylinder 51 moves in a vertical direction), the pressing plate cylinder 51 is fixed on the auxiliary platform 44, one end of the connecting rod 52 is hinged to a top end of the piston rod of the pressing plate cylinder 51, the other end of the connecting rod 52 is connected to the pressing plate 53 (the pressing plate 53 can be fixedly connected to the connecting rod 52 or connected through a bolt fastening manner, as long as a connection manner that the relative positions of the pressing plate and the connecting rod 52 do not change is achieved), one end of the supporting rod 54 is hinged to the auxiliary platform 44 or the pressing plate cylinder 51 (a cylinder body of the pressing plate cylinder 51).

Through the above arrangement mode, the piston rod of the pressing plate cylinder 51 reciprocates up and down, so that the pressing plate can be lifted up and pressed down, and when the circuit board is required to be pressed down through the pressing plate, the piston rod of the pressing plate cylinder 51 moves upwards to drive the pressing plate to press down, otherwise, the pressing plate is driven to lift up.

Second platen device 5:

referring to fig. 16, the pressing plate device 5 includes a pressing plate cylinder 51, a pressing plate 53 and a connecting rod 52, the pressing plate cylinder 51 is vertically fixed on the auxiliary platform 44, a free end of a piston rod of the pressing plate cylinder 51 is rigidly connected to one end of the connecting rod 52, the connecting rod 52 is horizontally arranged in the left-right direction (one end of the connecting rod 52 close to the working platform 3 may also be obliquely arranged, but the connecting rod 52 is not necessarily horizontally arranged), and the other end of the connecting rod 52 is rigidly connected to the pressing plate 53.

The working process of the plate pressing device 5 is as follows: the up-and-down movement of the piston rod of the pressing plate cylinder 51 can directly drive the pressing plate to move up and down, thereby realizing the purpose of pressing the circuit board.

With the first platen device 5, when the platen is in the raised state, any part of the platen is directly projected on the work platform 3, so that the platen may obstruct the placement of the circuit board when the circuit board is placed on the work platform 3.

For the second pressing plate device 5, when the pressing plate is in the upward-lifting state, the pressing plate is directly over the working platform 3, and when the circuit board is to be placed on the working platform 3, the circuit board can only be inserted from the side, which is troublesome.

In order to solve the interference problem of the pressing plate, the inventor further improves the clamp dismounting device 4 as follows:

the unclamping device 4 further comprises a base platform 45, the base platform 45 is fixed on the frame, a third cylinder and a second slide rail 46 are fixed on the base platform 45, the third cylinder and the second slide rail 46 are arranged in the left-right direction, the auxiliary platform 44 is installed on the base platform 45 through the second slide rail 46, the auxiliary platform 44 can slide left and right relative to the base platform 45, the free end of a piston rod of the third cylinder is connected with the auxiliary platform 44, and the third cylinder drives the auxiliary platform 44 to move in the left-right direction.

Specifically, when the circuit board needs to be placed on the working platform 3, the auxiliary platform 44 is pulled to the left (the clamping device 4 on the left side of the working platform 3) through the third cylinder, and the pressing plate device 5 is fixed on the auxiliary platform 44, so that the pressing plate device 5 can move left, the pressing plate is separated from the position right above the working platform 3, and the circuit board is not affected.

The number of the pressing plate devices 5 on each de-clamping device 4 is 2 or 3, so as to achieve better effect of pressing the circuit board.

The left side and the right side of the working platform 3 are respectively connected with a limiting block for relatively fixing the circuit board on the working platform 3 (mainly preventing the circuit board from moving on a horizontal position). The stopper can refer to patent number: 201510026920.5, the structure and function of the stopper in this application do not change, and therefore, the description thereof is omitted.

And as to the specific structure of the stripping jaw:

referring to fig. 2 to 4, the disassembling clamping jaw includes a housing 11, a first jaw 12, a second jaw 13 and a power mechanism, the first jaw 12 and the second jaw 13 are disposed opposite to each other, the first jaw 12 and the second jaw 13 have the same structure, hinge holes 14 (shown in fig. 4) are formed in the same positions of the first jaw 12 and the second jaw 13, and the first jaw 12 and the second jaw 13 are respectively hinged to the housing 11 through the respective hinge holes 14.

The first claw piece 12 can rotate around the hinge hole 14, and similarly, the second claw piece 13 can also rotate around the corresponding hinge hole 14, the positions of the end 12.1 of the first claw piece and the end 13.1 of the second claw piece are changed by the rotating first claw piece 12 and the second claw piece 13, that is, simply, the end 12.1 of the first claw piece and the end 13.1 of the second claw piece are close to or separated from each other, under the condition that the end 12.1 of the first claw piece and the end 13.1 of the second claw piece are close to each other, the gap 15 formed between the end 12.1 of the first claw piece and the end 13.1 of the second claw piece becomes smaller, if the clip 2 (hereinafter referred to as "clip") on the circuit board is positioned in the gap 15, as the gap 15 becomes smaller (the first claw piece 12 and the second claw piece 13 both rotate inwards), the end 12.1 of the first claw piece and the end 13.1 of the second claw piece can just grab the clip 2 (the closed state), at this time, force is applied to the detaching claw 1 through the outside, the detaching claw 1 is dragged backwards (corresponding to the fact that the second cylinder 42 works to drag the mounting platform 41 leftwards in the section 8 of the embodiment) (the detaching claw is kept locked in a closed state), and as the clip 2 is clamped on the circuit board and the position of the circuit board is relatively fixed, the detaching claw 1 can detach the clip 2 from the circuit board, so that the purpose of detaching the clip is achieved; then, the first claw piece 12 and the second claw piece 13 are rotated in the opposite directions, so that the gap 15 becomes large (this state is an open state of the release claw), and the clip 2 slides out of the gap 15.

It should be emphasized that the above-mentioned objects can be achieved only by controlling the free size of the gap 15, and therefore, the solutions for achieving the above-mentioned objects should be equivalent solutions, not limited to the solutions described in this document!

The first jaw 12 and the second jaw 13 are rotated such that the end 12.1 of the first jaw and the end 13.1 of the second jaw are brought towards or away from each other, and in the first position (closed state of the stripping jaw 1) the end 12.1 of the first jaw and the end 13.1 of the second jaw are brought towards each other to a first position, in which the end 12.1 of the first jaw and the end 13.1 of the second jaw cooperate with the outer shape of the clip 2 on the circuit board.

It should be noted that, the first claw piece 12 and the second claw piece 13 are driven to rotate by a power mechanism, which may be driven by a special power mechanism for the first claw piece 12, and driven by another special power mechanism for the second claw piece 13; the first claw piece 12 and the second claw piece 13 can be driven to rotate by the same power mechanism.

Objective construction of the clip: the clip 2 is clipped on the circuit board, the clip 2 has two slopes, i.e., an upper slope and a lower slope (the outer shape of the clip 2 can be seen in fig. 4 of patent No. 201510026920.5), and the inside of the clip 2 is hollow, so that the left and right sides (the left and right directions herein are named on the basis of the clip 2) of the clip 2 are hollow.

In consideration of the above, the inventor can adopt the following two design modes for the first claw piece 12 and the second claw piece 13:

description of the drawings: normally the circuit board is arranged horizontally and thus the two inclined surfaces of the clamp 2 on the circuit board are arranged up and down, respectively, and the relative positions of the first 12 and second 13 claws are explained based on this particular situation.

Referring to fig. 5 and 6, the first design is: the first jaw 12 and the second jaw 13 are arranged opposite to each other, and when the detachable jaw 1 is in the closed state, the tip 12.1 of the first jaw abuts against the upper inclined surface of the clip 2 (assuming that the clip 2 is located in the gap 15), and the tip 13.1 of the second jaw abuts against the lower inclined surface of the clip 2, so that the purpose of grasping the clip 2 is achieved.

To the first design, when pulling the clamping jaw 1 backward, because the first claw piece 12 and the second claw piece 13 are attached to the inclined plane of the clamp 2, if the clamping force of the clamp 2 is large enough, the clamp 2 may not be pulled down from the circuit board, but the first claw piece 12 and the second claw piece 13 cannot lock the clamp 2, and instead, the first claw piece 12 and the second claw piece 13 are collapsed (the gap 15 becomes large), and the object of the present invention cannot be achieved.

Of course, the clamping force of the clamp 2 is not large in consideration of the actual situation, which has not occurred through practical verification.

Referring to fig. 7 and 8, the second design approach: in order to solve the problem that the first design mode may possibly occur (the complete locking of the clamp 2 cannot be ensured), the first claw piece 12 and the second claw piece 13 are oppositely arranged left and right, the tail end 12.1 of the first claw piece and the tail end 13.1 of the second claw piece are respectively extended with the clamp nail 19, the first claw piece 12 and the second claw piece 13 are oppositely arranged left and right, so when the dismounting clamp jaw 1 is in a closed state, the tail end 12.1 of the first claw piece and the tail end 13.1 of the second claw piece respectively clamp the left side and the right side of the clamp 2, and the clamp nail 19 can extend into the clamp 2 because the left side and the right side of the clamp 2 are hollow; when the detaching jaw 1 is pulled backwards, even if the clamping force of the clamp 2 is large, the clamp 2 does not move backwards along with the detaching jaw 1, but the clamp 2 can be clamped by the clamp nail 19, so that the clamp 2 can be pulled backwards forcibly, and the clamp 2 is prevented from falling off.
