Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1, the present embodiment provides an automatic circuit board feeding device, which mainly includes the following components: a transfer mechanism 100, a shaping mechanism 200, a robot (not shown), and a feed mechanism 300.
In this embodiment, the conveying mechanism 100, the shaping mechanism 200, and the feeding mechanism 300 are sequentially arranged, the circuit board is automatically conveyed from the conveying mechanism 100 to the shaping mechanism 200, and after the shaping operation is completed at the shaping mechanism 200, the circuit board is conveyed to the feeding mechanism 300 by a manipulator to complete the automatic feeding operation.
Each of the parts will be described in detail below.
(1) The outlet end of the transfer mechanism 100 is connected to the inlet end of the shaping mechanism 200, and is used for sequentially conveying the circuit boards to the shaping mechanism 200 at the initial moment. The conveying mechanism 100 can be realized by an automatic conveying structure composed of a plurality of rollers arranged in parallel as shown in fig. 1, and can also be realized by a conveyor belt, which is not limited in particular.
(2) And the shaping mechanism 200 is used for shaping the circuit board before loading so as to ensure the stability of subsequent loading operation and electroplating quality. The shaping mechanism 200 includes a smooth platen 210, a platen mechanism 220, and a vacuum pump (not shown) connected to the smooth platen 210.
The inlet end of the smooth platform 210 is connected to the outlet end of the conveying mechanism 100, and the smooth platform 210 has a plurality of air suction holes uniformly formed on the surface thereof, so that the vacuum pump can be used for vacuuming, thereby smoothly and tightly adsorbing the circuit board conveyed to the smooth platform 210 on the smooth platform 210.
Referring to fig. 1 and fig. 2, the pressing plate mechanism 220 includes a first frame 221, a first horizontal sliding mechanism 222 is fixed on a table of the first frame 221, a vertical sliding mechanism 223 is slidably disposed on the first horizontal sliding mechanism 222, a roller bracket 224 is slidably disposed on the vertical sliding mechanism 223, a roller 225 is fixedly disposed on the roller bracket 224, and a length direction of the roller 225 is parallel to the table of the smooth platform 210.
The roller 225 can be moved not only in the horizontal direction but also in the vertical direction by the action of the first horizontal sliding mechanism 222 and the vertical sliding mechanism 223. The roller 225 functions as: after the circuit board is vacuum-adsorbed on the smooth platform 210, the circuit board surface is rolled to make the circuit board flat, thereby achieving the purpose of shaping.
To achieve a good shaping effect, the entire circuit board needs to be rolled to avoid missing the corner area of the circuit board, so the horizontal motion track of the roller 225 needs to cover the entire smooth platform 210. Therefore, in this embodiment, the initial position of the roller 225 is set at the entrance end of the smooth platform 210, the roller 225 is parallel to the side edge of the entrance end of the smooth platform 210, and the slidable distance of the roller 225 in the horizontal direction is not less than the vertical distance between the entrance end and the exit end of the smooth platform 210, so that the rolling surface of the roller 225 can cover the entrance end to the exit end of the smooth platform 210, that is, the entire smooth platform 210.
The specific operation process of shaping the circuit board by applying the shaping mechanism 200 is as follows:
at the initial moment, the roller 225 stays above the entrance end of the smooth platform 210;
when the circuit board is transported to the smooth platform 210 by the transport mechanism 100, the vacuum pump pumps vacuum to tightly adhere the circuit board to the surface of the smooth platform 210;
the height of the roller 225 is reduced through the vertical sliding mechanism 223, so that the roller 225 is pressed against the circuit board; then, the first horizontal sliding mechanism 222 controls the roller 225 to move from the inlet end to the outlet end of the smooth platform 210 and then return to the inlet end, so as to roll the whole circuit board;
after the roller 225 returns to the entrance end, the height of the roller 225 is raised by the vertical sliding mechanism 223, so that the roller 225 and the circuit board are separated from each other and located at a position above the entrance end of the smooth platform 210, and thus the shaping operation of the circuit board is completed.
During the shaping operation, the number of times the circuit board is rolled by the roller 225 may be set as required to achieve the best shaping effect.
(3) And the manipulator is arranged on one side of the smooth surface platform 210 and used for pushing the shaped circuit board on the smooth surface platform 210 to a preset board loading position on the feeding mechanism 300.
Due to the existence of various external factors (for example, the circuit board is inclined due to the action of external force) or self factors (for example, the specifications of the circuit board are different), the coordinate positions of the circuit boards on the smooth surface platform 210 cannot be kept completely consistent all the time, so that the loading position of the circuit board is easy to deviate, and the final clamping effect and the electroplating effect are influenced.
Therefore, in this embodiment, an automatic compensation adjustment function is further added:
an industrial camera 230 is additionally arranged above the central point of the smooth surface platform 210, the shooting range of the industrial camera can cover the whole smooth surface platform 210, and the industrial camera is used for shooting the smooth surface platform 210 and sending the shot to a computer end after the shaping mechanism 200 finishes shaping operation on the circuit board;
the computer end obtains the specific position of the current circuit board on the smooth surface platform 210 from the picture, and calculates compensation adjustment data according to the specific position;
the manipulator firstly performs corresponding posture adjustment according to the compensation adjustment data, and then grabs the circuit board on the smooth surface platform 210 and pushes the circuit board to the feeding mechanism 300, so that the accuracy of the feeding position of each circuit board is ensured.
In order to save the assembly space of the industrial camera 230 and improve the assembly convenience, in the embodiment, a camera support 240 is fixedly disposed on the top surface of the first frame 221 of the pressing plate mechanism 220, and the industrial camera 230 is fixed on the camera support 240.
(4) And a feeding mechanism 300 for completing the feeding operation of the circuit board.
As shown in fig. 1 and 3, the loading mechanism 300 includes a second frame 310, a loader mechanism 320, and a clamper 330.
A second horizontal sliding mechanism 311 is disposed on the table top of the second frame 310, the second horizontal sliding mechanism 311 includes a first end and a second end along the sliding track direction, the first end is close to the smooth surface platform 210, and the second end is far away from the smooth surface platform 210.
The plate loading mechanism 320 is slidably arranged on the second horizontal sliding mechanism 311 and can reciprocate between the first end and the second end along the sliding track; the clamping mechanism 330 is fixedly disposed on the table of the second frame 310 and located at one side of the second end of the second horizontal sliding mechanism 311.
The board loading mechanism 320 is used for absorbing the circuit board conveyed by the mechanical hand and conveying the circuit board to the clamping mechanism 330. This loader mechanism 320 includes: a rotary platform 321, a carrier plate base 322, a carrier plate 323, a vacuum suction strip 324 and a clamp opening mechanism 325.
The carrier plate 323 is fixed on the carrier plate base 322, a horizontal first slide rail 326 is arranged on the carrier plate 323, two parallel and vertical vacuum suction plate bars 324 are slidably arranged on the first slide rail 326, and the distance between the two vacuum suction plate bars 324 can be adjusted according to the size of the circuit board to adapt to the circuit boards with different specifications. The top of the carrier plate 323 is further provided with a clamp opening mechanism 325 driven by an air cylinder, and the clamp opening mechanism 325 can move upwards under the driving action of the air cylinder to push the main clamp of the electroplating clamp to open.
The rotating platform 321 is slidably mounted on the second horizontal sliding mechanism 311, can slide along the track of the second horizontal sliding mechanism 311, and can also rotate, and the rotating shaft is perpendicular to the table top of the second rack 310. A horizontal second slide rail 327 is disposed on the top surface of the rotating platform 321, a track direction of the second slide rail 327 is perpendicular to a track direction of the first slide rail 326, and the carrier board base 322 carrying the carrier board 323 is slidably disposed on the second slide rail 327.
The plate mounting process of the plate mounting mechanism 320 specifically includes:
at the initial time of loading, the plate loading mechanism 320 is located at the first end of the second horizontal sliding mechanism 311 close to the smooth platform 210; when the manipulator grabs the circuit board and pushes the circuit board to the front of the board loading mechanism 320, the carrier plate 323 drives the vacuum suction plate strip 324 to move forward towards the manipulator along the second track until the vacuum suction plate strip 324 sucks the circuit board on the manipulator; after the vacuum suction bar 324 sucks the circuit board, the rotary platform 321 rotates 180 degrees and horizontally slides to the second end of the second horizontal sliding mechanism 311 so that the circuit board faces the chuck 330. Therefore, the loader 320 can quickly, reliably and accurately transport the circuit board from the robot position to the position where the loader 330 is located.
The clamping mechanism 330 is used for opening and closing an electroplating clamp (not shown in the figure) and loading the circuit board onto the electroplating clamp under the cooperation of the plate loading mechanism 320.
The clamping mechanism 330 comprises a third frame 331, and the third frame 331 is sequentially provided with a top clamping mechanism 332, an auxiliary clamping opening and closing mechanism 333 and a cathode shielding plate opening and closing mechanism 334 from top to bottom. Because some electroplating clamps on the market at present comprise an auxiliary clamp and a cathode shielding plate besides a main clamp, in order to meet the automatic clamping opening requirement of the electroplating clamp with such a structure to improve the clamping efficiency, compared with the conventional clamping mechanism 330, the clamping mechanism 330 of the embodiment further comprises an auxiliary clamp opening and closing mechanism 333 and a cathode shielding plate opening and closing mechanism 334.
The top clamping mechanism 332 of the clamping mechanism 330 and the opening clamping mechanism 325 of the plate clamping mechanism 320 cooperate with each other to open and close the main clamp of the electroplating clamp, specifically: when the front faces of the plate loading mechanism 320 and the clamping mechanism 330 are opposite, the clamp opening mechanism 325 is lifted to push the main clamp to open, and meanwhile, the top clamping mechanism 332 is abutted against the main clamp to prevent the main clamp from moving when being opened by stress.

When the first opening and closing motor rotates forwards or reversely, the distance between the opening and closing part of the left auxiliary clamp and the opening and closing part of the right auxiliary clamp is increased or reduced, so that the auxiliary clamps are opened and closed.

When the second opening and closing motor rotates forwards or reversely, the distance between the opening and closing part of the left cathode shield and the opening and closing part of the right cathode shield is increased or reduced, so that the opening and closing of the cathode shields are realized.
The specific process of loading the circuit board on the electroplating clamp comprises the following steps: when the plate loading mechanism 320 moves to the clamping mechanism 330, the sub-clamp and the cathode shield of the electroplating clamp are respectively opened through the sub-clamp opening and closing mechanism 333 and the cathode shield opening and closing mechanism 334; the clamp opening mechanism 325 ascends, the main clamp of the electroplating clamp is opened under the cooperation of the top clamp mechanism 332, and the circuit board enters the electroplating clamp; when the main clamp, the auxiliary clamp and the cathode shielding plate of the electroplating clamp are closed, the electroplating clamp can stably clamp the circuit board, and then the normal electroplating process is carried out.
To sum up, the process of using the automatic circuit board feeding device of this embodiment to carry out the material loading is: firstly, automatically conveying the circuit board to the smooth surface platform 210 by the conveying mechanism 100, and performing rolling shaping on the circuit board after the circuit board is vacuum-absorbed by the smooth surface platform 210; then, the manipulator grabs the circuit board after performing corresponding posture adjustment and conveys the circuit board to the front of the board loading mechanism 320; the suction strips of the board mounting mechanism 320 move forward to suck the circuit board, and then rotate 180 degrees and move to the clamping mechanism 330; and opening the electroplating clamp to enable the circuit board to enter the electroplating clamp, and closing the electroplating clamp, so that the electroplating clamp clamps the circuit board, thereby finishing the loading operation of the circuit board.
