Description

A feeding machine

Technical Field

The utility model relates to circuit board production equipment, in particular to a blanking machine.

Background Art

In the production process of circuit boards (especially FPC), the circuit boards are connected to each other, but in the production process, the circuit boards need to be separated at the connected positions. Since the FPC circuit boards are flexible, they are generally moved under the clamping of the jig during the production process. At this time, since the FPC circuit boards need to be separated at the connection, the jig is provided with corresponding hollowing at the FPC connection. In order to improve the stability and efficiency of separating the FPC circuit boards, a laser machine is generally used for cutting. After cutting, the FPC is a separate component. In order to facilitate subsequent production work, it is necessary to separate the jig and the FPC at this time, and collect the separate FPCs at the same time. Therefore, there is an urgent need for an automated equipment for classification and collection after laser cutting to improve production efficiency.

As shown in Figures 1 to 8, a blanking machine is characterized in that it includes a workbench 1, and the upper side of the workbench 1 is provided with

The feeding conveying structure 2 is provided with a conveyor belt for receiving the jig carrying the circuit board after laser treatment;

The rotating structure 3 is used to take out and flip the jig carrying the circuit board on the upper side of the conveying structure;

A mobile manipulator 4 is used to take out the jig and the circuit board from the jig carrying the circuit board;

The material collecting structure 5 is used to collect the circuit boards taken out by the mobile manipulator 4 .

During the production process, after laser cutting at the previous workstation, the jig carrying the separated circuit boards flows to the position of this equipment. At this time, the cover of the jig is taken out, and then the individually separated circuit boards after cutting are taken out into the material box, thus completing the laser cutting unloading process. The entire process is automated to improve production efficiency.

At this time, the mobile manipulator 4 is used to move the jig and the circuit board. In the present embodiment, the mobile manipulator 4 is provided with a suction cup structure 41 for fixing the jig and the circuit board. The suction cup structure 41 includes a suction cup spindle 411. A suction cup bracket 412 is fixed to the lower side of the suction cup spindle 411.

At this time, in order to be able to take out different products through the suction cup structure 41, in this embodiment, the suction cup structure 41 is provided with a product suction cup, a cover plate suction cup, and a carrier plate suction cup for taking out the corresponding products. At this time, since the circuit board is different in size from the cover plate and the carrier plate, the product suction cup can be set at the innermost position, and then the cover plate suction cup and the carrier plate suction cup are set on the outside, so as to achieve the purpose of distributing different suction cups in different positions, thereby achieving the purpose of taking out the product, the cover plate, and the carrier plate.

The rotating structure 3 is used to rotate the turning fixture. In this embodiment, the rotating structure 3 includes a rotating base 31, and the rotating base 31 is fixed to the workbench 1 through a lateral moving structure.

The rotating fixed frame 32 is fixed on the upper side of the rotating base 31, and the rotating fixed frame 32 is connected to the rotating base 31 through a vertical moving structure.

There are two rotating side walls 33, which are fixed at intervals on both sides of the rotating fixed frame 32.

The rotating bracket 34 is rotatably connected to the rotating side wall 33. There are two rotating brackets 34, which are respectively located at the inner sides of the two rotating side walls 33.

The rotating clamping member 35 is located at the side of the rotating bracket 34. The rotating clamping member 35 includes a plurality of finger cylinders. The piston rods of the finger cylinders are provided with clamping parts for clamping the fixture.

The rotating motor 36 has a shaft connected to the rotating bracket 34 via a synchronous belt transmission structure, and is used to control the rotation of the rotating bracket 34 .

Under the action of the rotating motor 36, the rotating bracket 34 and the rotating side wall 33 rotate relative to each other, so that the rotating clamp 35 can rotate synchronously, and the jig clamped by the rotating clamp 35 follows the synchronous rotation. At the same time, after the rotating clamp 35 clamps the fixed jig, under the action of the lateral moving structure and the vertical moving structure, the rotating side wall 33, the rotating bracket 34, and the rotating clamp 35 can move synchronously in the lateral and vertical directions, so that the jig can be moved to the position of the material taking platform 6.

Since the circuit boards need to be taken out one by one, in order to improve production efficiency, in this embodiment, a material taking platform 6 is also provided on the workbench 1. The material taking platform 6 is located on the upper side of the conveyor belt of the feed conveyor structure 2. The material taking platform 6 includes an upper conveyor belt 61 and a lower conveyor belt 62 distributed in the upper and lower layers. A positioning structure 63 for positioning the jig is provided on the side of the upper conveyor belt 61. The positioning structure 63 includes a positioning cylinder and a positioning plate. A separation structure 64 for separating the jig is also provided on the side of the upper conveyor belt 61. The separation structure 64 includes a separation cylinder and a separation plug. The separation plug is inserted between the carrier plate and the cover plate of the jig under the action of the separation cylinder. Further, the rotating structure 3 and the material taking platform 6 are provided in plurality, and the material taking platform 6 is arranged in parallel with the feed conveyor structure 2. At this time, the material-collecting platform 6 is arranged corresponding to the rotating structure 3, and the material-collecting platform 6 is located at the upper side of the feeding conveying structure 2, specifically, at the upper side of the conveyor belt of the feeding conveying structure 2. During the production process, the circuit board after laser cutting flows into the feeding conveyor belt structure position (carried and moved by the jig), and then moves to the material-collecting platform 6 position under the action of the rotating structure 3. At this time, the jig is placed at the upper conveyor belt 61 position. At this time, the upper conveyor belt 61 is moved to a position higher than the conveyor belt, and the lower conveyor belt 62 is flush with the conveyor belt, so that the upper conveyor belt 61 stops rotating and the lower conveyor belt 62 continues to operate, so that the conveyor belt of the feeding conveying structure 2 and the lower conveyor belt 62 can continue to convey the jig. Move the jig to the next set material collection platform 6 and rotating structure 3 position. When the jig moves to the position of the upper conveyor belt 61, the upper conveyor belt 61 is provided with a positioning structure 63 for positioning the jig. At this time, the positioning structure 63 is a positioning cylinder and a positioning plate. Under the action of the positioning cylinder, the positioning plate abuts against the jig to determine the position of the jig and the circuit board, so as to facilitate the moving structure to move the jig and the circuit board. At this time, in order to facilitate the separation of the cover plate and the circuit board, in this embodiment, a separation cylinder and a separation plug are provided. Under the action of the separation cylinder, the separation plug is inserted into the groove between the cover plate and the carrier plate. When the cover plate is taken out by the corresponding suction cup of the moving structure, the carrier plate can be taken out at the same time.

After the circuit board is taken out, it is necessary to collect the circuit board through a material box. In this embodiment, the material collection structure 5 includes a material box storage mechanism 51 for storing empty material boxes;

The receiving conveyor belt 52 is used to place individual boxes.

The material box moving mechanism 53 is used to move the material box loaded with circuit boards;

The material box collecting mechanism 54 is used to collect the material boxes loaded with circuit boards.

Specifically, the material box moving structure includes a linear guide rail 531 parallel to the material receiving conveyor belt 52, and a material box moving cylinder 532 moving along the direction of the linear guide rail 531 is provided on the upper side of the linear guide rail 531, and the piston rod of the material box moving cylinder 532 is connected to a moving plate 533, and the moving plate 533 is provided with a raised limiting plate 534, and at least two limiting plates 534 are provided. The limiting plates 534 move up and down under the action of the material box moving cylinder 532, so that they can abut against the side of the material box, and when the material box moving cylinder 532 moves along the direction of the linear guide rail 531, the limiting plates 534 move the material box at the conveyor belt position to the position of the material box collecting mechanism 54.

At this time, the limit plates 534 are provided with 3 intervals, and the width of the two adjacent limit plates 534 on the left side is adapted to the width of the material box. The material box moving cylinder 532 is connected to the workbench 1 through a linear motor. In this way, under the action of the linear motor and the linear guide 531, the material box moving cylinder 532 can move back and forth. During the movement, the material box moving cylinder 532 can control the movement of the upper limit plate 534. When the empty material boxes are moved to the position of the receiving conveyor belt 52 one by one, the mobile manipulator 4 moves individual circuit boards one by one to the material box at the position of the receiving conveyor belt 52. After the material box is full, under the action of the linear motor and the material box moving cylinder 532, the two limit plates 534 on the left side are respectively abutted against the two side edges of the material box, and then the linear motor controls the material box moving cylinder 532 to move horizontally along the direction of the receiving conveyor belt 52, so that the material box can be controlled to move to the position of the material box collecting mechanism 54.

Specifically, the material box collecting mechanism 54 includes a discharging conveyor belt 541, a discharging movable plate 542533 that moves up and down is provided on the upper side of the discharging conveyor belt 541, a discharging cylinder 543 is provided on the upper side of the discharging movable plate 542533, and a discharging clamping plate 544 is connected to the piston rod of the discharging cylinder 543, and the discharging clamping plate 544 is located at the lower side of the material box moved to this position. Further, the discharging movable plate 542533 is located between two parallel conveyor belts of the discharging conveyor belt 541, and the discharging movable plate 542533 moves up and down, thereby moving the material box at the position of the discharging clamping plate 544 to the position of the discharging conveyor belt 541. When the material box moves to the position of the discharge clamping plate 544, the discharge clamping plate 544 drags and fixes the bottom of the material box under the action of the discharge cylinder 543, and then the discharge moving plates 542533 move upward to the lower side of the material box, and the discharge clamping plate 544 moves outward. When the discharge moving plates 542533 move downward, the material box is supported and moved downward until the material box moves to the upper side of the discharge conveyor belt 541, so that the material box filled with circuit boards can be transferred out.

As for the material box storage mechanism 51, in this embodiment, a plurality of empty material boxes are first piled up, and then the up and down movement of the material boxes is controlled by the action of the vertically arranged upper and lower cylinders. At the same time, a horizontal cylinder and a horizontal plate are provided for inserting in the second to last material box position, and an output conveyor belt is provided for transferring the material boxes to the material box conveyor belt position, thereby realizing active loading of the material boxes one by one.
