Detailed Description
Referring to fig. 1 and 2, the invention provides a disassembling jaw 1, which comprises a shell 11, a first jaw 12, a second jaw 13 and a power mechanism, wherein the first jaw 12 and the second jaw 13 are oppositely arranged, the first jaw 12 and the second jaw 13 have the same structure, the same position of the first jaw 12 and the second jaw 13 is provided with a hinge hole 14 (shown in fig. 3), and the first jaw 12 and the second jaw 13 are respectively hinged on the shell 11 through respective hinge holes 14.
Referring to fig. 3, the first jaw 12 is rotatable around the hinge hole 14, and the second jaw 13 is rotatable around the corresponding hinge hole 14, so that the positions of the end 12.1 of the first jaw and the end 13.1 of the second jaw are changed by the rotating first jaw 12 and second jaw 13, in which, in brief, the end 12.1 of the first jaw and the end 13.1 of the second jaw are close to each other or separated from each other, under the condition that the end 12.1 of the first jaw and the end 13.1 of the second jaw are close to each other, a gap 15 formed between the end 12.1 of the first jaw and the end 13.1 of the second jaw becomes smaller, and if a clamp 2 (hereinafter referred to as a "clamp") on a printed circuit board is located in the gap 15, the end 12.1 of the first jaw and the end 13.1 of the second jaw can just grasp the clamp 2 (this state is a state that the clamp is closed), and then the clamp 1 is pulled to the printed circuit board is kept at the closed by pulling the clamp 2, and the clamp 1 is detached from the printed circuit board is kept at the closed by pulling the clamp 1; then, the first and second claw pieces 12 and 13 are reversely rotated again, so that the gap 15 becomes large (this state is the open state of the split jaws), and the clip 2 slides out of the gap 15.
It should be emphasized that the above object is achieved by controlling the free increase or decrease of the gap 15, and thus the solutions for achieving the above object should all belong to the equivalent technical solutions and are not limited to the technical solutions presented in the present specification-!
The rotating first and second jaws 12, 13 bring the ends 12.1, 13.1 of the first and second jaws close to or separate from each other, and at said ends 12.1, 13.1 of the first and second jaws close to each other to a first station, in which (the closed state of the jaws 1 is detached) said ends 12.1 of the first and second jaws cooperate with the shape of the clip 2 on the printed circuit board.
In addition, the first claw 12 and the second claw 13 are driven to rotate by a power mechanism, which can be driven by a special power mechanism for the first claw 12, and the second claw 13 is driven by another special power mechanism; the first claw piece 12 and the second claw piece 13 can be driven to rotate by the same power mechanism.
Objective structure of clip: the clip 2 is clamped on a printed circuit board, the clip 2 has two inclined surfaces, namely an upper inclined surface and a lower inclined surface (the outer shape of the clip 2 can be seen in fig. 4 of patent number 201510026920.5), and the inside of the clip 2 is hollow, so that the left and right sides of the clip 2 (the left and right directions are named based on the clip 2 herein) are hollow.
The inventors consider the above, the first and second claw pieces 12 and 13 may be designed in the following two ways:
description: normally the printed circuit board is arranged horizontally, so that the two inclined surfaces of the clip 2 on the printed circuit board are arranged up and down, respectively, and so that the relative positions of the first and second claw pieces 12, 13 are explained based on this specific case.
Referring to fig. 3-5, the first design approach is: the first jaw 12 and the second jaw 13 are arranged vertically opposite to each other, and when the dismounting jaw 1 is in the closed state, the tail end 12.1 of the first jaw is attached to the upper inclined surface of the clip 2 (assuming that the clip 2 is positioned in the gap 15), and the tail end 13.1 of the second jaw is attached to the lower inclined surface of the clip 2, so that the purpose of grasping the clip 2 is achieved.
In the first design, when the clamping jaw 1 is pulled back and detached, since the first jaw 12 and the second jaw 13 are attached to the inclined surfaces of the clip 2, if the clamping force of the clip 2 is sufficiently large, the clip 2 may not be pulled down from the printed circuit board, but the first jaw 12 and the second jaw 13 may not lock the clip 2, and the first jaw 12 and the second jaw 13 may be broken (the gap 15 may become large), so that the object of the present invention may not be achieved.
Of course, considering the actual situation, the clamping force of the clip 2 is not large, and it has been verified that the above situation does not occur.
Referring to fig. 6 and 7, the second design approach is: in order to solve the possible problem of the first design manner (the clamp 2 cannot be fully locked), 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 clamping nail 19, and when the clamping 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 clamp the left and right sides of the clamp 2 respectively, and the clamping nail 19 can extend into the clamp 2 because the left and right sides of the clamp 2 are hollow; when the clamping 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 clamping jaw 1, but the clamp 19 can clamp the clamp 2, so that the clamp 2 can be pulled backwards forcefully, and the clamp 2 is prevented from falling off.
Referring to fig. 4, the first jaw 12 and the second jaw 13 are L-shaped, the hinge hole 14 on the first jaw 12 is located at a corner position of the first jaw 12, the hinge hole 14 on the second jaw 13 is located at a corner position of the second jaw 13, the starting ends of the first jaw 12 and the second jaw 13 are provided with waist slots 17, the waist slots 17 on the first jaw 12 and the waist slots 17 on the second jaw 13 are connected through connecting pins, the number of the power mechanisms is one, and the output end of the output shaft of the power mechanism is directly or indirectly connected with the starting ends of the first jaw 12 and the second jaw 13 to push the first jaw 12 and the second jaw 13 to rotate.
The first claw piece 12 is designed in the mode, the power mechanism can push the first claw piece 12 and the second claw piece 13 to rotate simultaneously only by one power mechanism, and the first claw piece 12 and the second claw piece 13 are connected through the connecting pin, and the first claw piece 12 and the second claw piece 13 are provided with the corresponding waist slots 17, so that the rotation amplitude of the first claw piece 12 and the second claw piece 13 is limited through the waist slots 17, and the first claw piece 12 and the second claw piece 13 are relatively ensured to rotate freely in the corresponding amplitude.
The shell 11 is internally provided with a mounting groove, the power mechanism is arranged in the mounting groove, the power mechanism is a first air cylinder 16, the free end of a piston rod of the first air cylinder 16 is connected with the starting end of the first claw piece 12 and the starting end of the second claw piece 13 through the connecting pin, and the symmetry line between the first claw piece 12 and the second claw piece 13 is in the same straight line with the axis of the first air cylinder 16.
The axis of the first cylinder 16 passes through the center of the gap 15, and since the piston rod of the first cylinder 16 can only move in the direction of the axis, the connecting pin is also located on the axis, thereby ensuring that the first jaw 12 and the second jaw 13 are identical in amplitude when moving, to ensure that the clip 2 is just gripped (the clip 2 is also located just on the axis).
The detachable clamping jaw 1 can be further connected with an inclined hopper 18 for directionally inducing the detached clamp 2.
Referring to fig. 8-10, the invention further provides a clip removing machine, which comprises a frame, wherein a working platform 3 is arranged on the frame, and a clip removing device 4 is respectively arranged on the left side and the right side of the working platform 3.
Work platform 3: for carrying a printed circuit board (including a bezel);
clip removing device 4: for removing clips from a printed circuit board.
It should be noted that, when the clip 2 is used to fix the printed circuit board and the frame, the clip 2 is usually clamped on the left and right sides of the printed circuit board, and the front and rear sides of the printed circuit board are clamped without the clip 2.
Thus, when the printed circuit board (with the frame and the clips 2) is placed on the work platform 3, the left and right sides of the work platform 3 coincide with the left and right sides of the printed circuit board. So the left clamp removing device 4 of the working platform 3 can remove the clamp on the left side of the printed circuit board, and the right clamp removing device 4 of the working platform 3 can remove the clamp on the right side of the printed circuit board.
Regarding the clip removing device 4:
referring to fig. 10-12, the clip removing device 4 includes a mounting platform 41, a second air cylinder 42 and a first sliding rail 43, wherein a plurality of clip removing jaws 1 are mounted on the mounting platform 41, the clip removing jaws 1 are arranged on the mounting platform 41 in a front-back direction, the direction of the first sliding rail 43 is a left-right direction, the mounting platform 41 is mounted on the first sliding rail 43, the mounting platform 41 can slide in the left-right direction, the 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 to move on the first sliding rail 43 by the second air cylinder 42.
Taking the clamping device 4 at the left side of the working platform 3 as an example, the clamping process will be described:
the printed 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 sliding rail 43, and when the mounting platform 41 reaches the rightmost side, the clamping disassembly jaws 1 on the mounting platform 41 exactly correspond to the clamps on the printed circuit board, and each clamping disassembly jaw 1 works to clamp the clamps (the specific working process is seen in the second section of the specific embodiment); then, the second air cylinder 42 works to drag the mounting platform 41 leftwards, so that the dismounting jaw 1 drags leftwards (the rear dragging of the dismounting jaw 1 corresponding to the second section of the specific embodiment) to realize the purpose of dismounting the clamp, the dismounting jaw 1 is opened, and the clamp automatically falls from the dismounting jaw 1.
It should be emphasized that the clamping device 4 on the left side of the working platform 3 and the clamping device 4 on the right side work simultaneously, so that the clamps on the left side and the right side of the printed circuit board are simultaneously dismounted, and the stress balance of the printed circuit board in the clamping process is relatively ensured.
In addition, the disassembling jaw 1 on the mounting platform 41 is detachable, a specific number of disassembling jaws 1 (the number of the disassembling jaws 1 corresponds to the number of the clips 2 on one side of the printed circuit board) can be mounted on the mounting platform 41 according to actual conditions, and meanwhile, the front and back positions of the disassembling jaws 1 on the mounting platform 41 can be adjusted, so that each disassembling jaw 1 can exactly correspond to one position of the clip 2 to be disassembled. Specific: a slideway can be arranged on the mounting platform 41, the dismounting jaw 1 is fixed on the slideway, the adjustment of the front and back positions of the dismounting jaw 1 can be realized by sliding the dismounting jaw 1 on the slideway, and after the dismounting jaw 1 is adjusted to a proper position, the dismounting jaw 1 can be relatively fixed on the mounting platform 41 by a locking mechanism (such as a locking bolt).
The inventor considers that in the practical application situation, when the clamping jaw 1 is used for clamping the clamp and dragging the clamp 2 during the clamping process, the printed circuit board may be dragged, and in order to ensure that the relative position of the printed circuit board and the working platform 3 is not changed all the time during the process, the invention also improves as follows:
referring to fig. 11, each clip removing system further includes an auxiliary platform 44, the second air cylinder 42 and the first slide rail 43 are respectively fixed on the auxiliary platform 44, and the auxiliary platform 44 is provided with a pressing plate device 5.
The main functions of the platen device 5 are: when the clamp is detached, 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 printed circuit board cannot displace, and after the clamp is separated from the printed circuit board, the pressing plate is lifted up again.
To achieve the above object, the platen device 5 may employ one of the following two modes.
A first platen device 5:
referring to fig. 13 and 14, the platen device 5 includes a platen cylinder 51, a platen 53, a link 52, and a support rod 54, the platen cylinder 51 is vertically disposed (a piston rod of the platen cylinder 51 moves in a vertical direction), the platen cylinder 51 is fixed on the auxiliary platform 44, one end of the link 52 is hinged to a top end of the piston rod of the platen cylinder 51, the other end of the link 52 is connected with the platen 53 (the platen 53 may be fixedly connected with the link 52 or connected by means of bolt fastening, as long as a connection manner in which a relative position between the platen and the link 52 does not change is achieved), one end of the support rod 54 is hinged to the auxiliary platform 44 or the platen cylinder 51 (a cylinder body of the platen cylinder 51), and the other end of the support rod 54 is hinged to a middle position of the link 52.
Through the arrangement mode, the lifting and the pressing of the pressing plate can be realized through the up-and-down reciprocating motion of the piston rod of the pressing plate cylinder 51, and particularly when the printed circuit board is required to be pressed by the pressing plate, the piston rod of the pressing plate cylinder 51 moves upwards to drive the pressing plate to press down, and conversely, the pressing plate is driven to lift.
A second platen device 5:
referring to fig. 15, the platen device 5 includes a platen cylinder 51, a platen 53 and a link 52, the platen cylinder 51 is vertically fixed on the auxiliary platform 44, a free end of a piston rod of the platen cylinder 51 is rigidly connected to one end of the link 52, the link 52 is horizontally disposed in the left-right direction (one end of the link 52 near the working platform 3 may also be disposed obliquely downward, instead of the link 52 being disposed horizontally), and the other end of the link 52 is rigidly connected to the platen 53.
The working process of the pressing plate 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 achieving the purpose of pressing the printed circuit board.
With the first type of platen device 5, any part of the platen is directly projected onto the work platform 3 in the state in which the platen is lifted, and thus the platen may hinder placement of the printed circuit board when the printed circuit board is placed on the work platform 3.
For the second type of pressing plate device 5, the pressing plate is directly above the working platform 3 in the lifted state, and when the printed circuit board is to be placed on the working platform 3, the printed circuit board can only be inserted from the side, which is troublesome.
To solve the interference problem of the above-mentioned pressing plate, the inventors also made the following improvements to the clip removing device 4:
the clamping disassembling device 4 further comprises a base platform 45, the base platform 45 is fixed on the frame, a third air cylinder and a second sliding rail 46 are fixed on the base platform 45, the third air cylinder and the second sliding rail 46 are arranged in the left-right direction, the auxiliary platform 44 is mounted on the base platform 45 through the second sliding 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 air cylinder is connected with the auxiliary platform 44, and the third air cylinder drives the auxiliary platform 44 to move in the left-right direction.
Specifically, when the printed circuit board needs to be placed on the working platform 3, the auxiliary platform 44 is pulled leftwards (the clamping device 4 on the left side of the working platform 3) through the third air cylinder, and the pressing plate device 5 is fixed on the auxiliary platform 44, so that the pressing plate device 5 can move leftwards, the pressing plate is separated from the position right above the working platform 3, and the placement of the printed circuit board is not affected.
The number of the pressing plate devices 5 on each clamping disassembling device 4 is 2 or 3, so that the effect of pressing the printed circuit board is better achieved.
Limiting blocks are respectively connected to the left and right sides of the working platform 3 for relatively fixing the printed circuit board (mainly placing the printed circuit board to move on the horizontal position) on the working platform 3. The limiting block can be seen in patent numbers: the structure and function of the stopper in 201510026920.5 are not changed, and will not be described in detail here.
Other settings:
the safety grating 6 is further arranged above the working platform 3, and when the printed circuit board is placed on the working platform 3 manually, the safety grating 6 can automatically detect work, so that the clamp dismounting device 4 is controlled to stop acting, and workers are prevented from being injured.
