[0023] Step 2: The transfer mechanism grabs the FPC to the left working platform corresponding to the dispensing mechanism. The spray valve on the left side performs the dispensing action.

This cycle continues continuously until it is full of a certain number of sheets, and then a full signal is given. The operator pulls out the thousand-layer rack and then puts in another thousand-layer rack.

Detailed implementation manner

[0043] This detailed implementation manner is an automatic dispensing device for FPC flexible circuit boards. The structural schematic diagram is as Figures 1-13 shown. The dispensing device includes a base 1, on which a dispensing mechanism 2 is installed. There are two independently operating working platforms 3 installed on the base 1. A transfer mechanism 4 for transferring materials is installed on the base 1. A material collecting machine 5 is arranged on one side surface of the base 1. A feeding mechanism 6 is installed on the base 1. And two second linear motors 7 for driving the movement of the working platforms 3 are installed on the base 1;

[0044] The dispensing mechanism 2 includes two mounting brackets 201 fixedly installed on the base 1, a first linear motor 202 fixedly installed on the tops of the two mounting brackets 201, two first sliding blocks 203 driven by the first linear motor 202, a housing 204 fixedly installed on the side of the first sliding block 203 away from the first linear motor 202, a first driving motor 205 fixedly installed on the top of the housing 204, a first lead screw 206 fixedly installed on the output end of the first driving motor 205, a first nut block 207 threadedly installed on the first lead screw 206, an L-shaped connecting plate 208 fixedly installed on the first nut block 207, a mounting plate 209 fixedly installed on the L-shaped connecting plate 208, and a spray valve 210 fixedly installed on the mounting plate 209. The structure of the spray valve 210 is prior art and will not be described in detail here;

[0045] When the first driving motor 205 drives the first lead screw 206 to rotate clockwise, the first lead screw 206 can drive the first nut block 207 threadedly installed thereon to move downward during rotation. During the downward movement of the first nut block 207, it can drive the L-shaped connecting plate 208 fixedly installed thereon to move downward. During the downward movement of the L-shaped connecting plate 208, it can drive the mounting plate 209 and the spray valve 210 to move downward synchronously to the dispensing position, and then perform the dispensing action;

[0046] Similarly, when the first driving motor 205 drives the first lead screw 206 to rotate counterclockwise, it can cause the mounting plate 209 and the spray valve 210 to move upward synchronously;

[0047] Therefore, after the dispensing action is completed, the first driving motor 205 drives the first lead screw 206 to rotate counterclockwise to cause the mounting plate 209 and the spray valve 210 to move upward synchronously to reset.

[0048] Each first nut block 207 is provided with two L-shaped connecting plates 208, and the two L-shaped connecting plates 208 are symmetrically installed on both sides of the first nut block 207. There is a gap between the two L-shaped connecting plates 208 and the housing 204. The ends of the two L-shaped connecting plates 208 away from the first nut block 207 are respectively fixedly connected to both ends of the mounting plate 209. Under the action of this gap, the L-shaped connecting plate 208 can be prevented from contacting the housing 204 during movement, so that the movement of the L-shaped connecting plate 208 and the mounting plate 209 can be realized;

[0049] The bottom end of the first lead screw 206 is rotatably installed on the inner bottom wall of the housing 204 through a bearing, and the housing 204 plays a supporting role for the first lead screw 206;

[0050] On the sides of the two L-shaped connecting plates 208 close to the first linear motor 202, first sliders 211 are fixedly installed. On the inner wall of one side of the housing 204 close to the first linear motor 202, two first slide rails 212 that cooperate with the first sliders 211 are fixedly installed, and the two first sliders 211 are respectively slidably installed on the two first slide rails 212;

[0051] With the cooperation of the first sliders 211 and the first slide rails 212, it can play a guiding role in the movement of the L-shaped connecting plate 208, making the movement of the L-shaped connecting plate 208 smoother, so that the mounting plate 209 and the spray valve 210 also become smoother during the movement;

[0052] Under the action of the first linear motor 202, it can drive the spray valve 210 to move in the X-axis direction. Under the action of the second linear motor 7, it can drive the working platform 3 to move in the Y-axis direction. And the spray valve 210 can move in the Z-axis direction under the cooperation of the first driving motor 205 and the first lead screw 206. That is, the spray valve 210 in this application can move flexibly in the X-axis, Y-axis, and Z-axis directions, so that the spray valve 210 can move according to the dispensing position of the product.

[0053] The material receiving machine 5 includes a frame 501, a thousand-layer rack 502 arranged on one side of the inner cavity of the frame 501, a drag net 503 placed on the thousand-layer rack 502, a lifting mechanism 504 arranged on one side of the inner cavity of the frame 501 for lifting the thousand-layer rack 502 and the drag net 503, and a clamping mechanism 505 arranged on the frame 501 for clamping the drag net 503;

[0054] The thousand-layer rack 502 includes a frame 5021, universal wheels 5022 installed at the four corners of the bottom of the frame 5021, first U-shaped plates 5023 fixedly installed on the inner walls of the front and rear sides of the frame 5021, and a handle 5024 hinged to the inner top wall of the front side of the frame 5021;

[0055] On the frame 501, second U-shaped plates 5011 are symmetrically and fixedly installed. On the outer sides of the two second U-shaped plates 5011, L-shaped plates 5013 are fixedly installed. One end of the L-shaped plate 5013 away from the second U-shaped plate 5011 is fixedly installed on the frame 501. The drag net 503 can be slidably placed on the inner sides of the two second U-shaped plates 5011 that are close to each other. That is, when the clamping mechanism 505 extracts the drag net 503 from the thousand-layer rack 502, the two sides of the drag net 503 slide inside the two second U-shaped plates 5011 respectively. When the drag net 503 is completely extracted from the thousand-layer rack 502, the two sides of the drag net 503 are respectively located inside the two second U-shaped plates 5011;

[0056] The universal wheels 5022 can adopt self-locking universal wheels, and with the action of the universal wheels 5022, the whole thousand-layer rack 502 is convenient to move;

[0057] On the left and right sides of the handle 5024 and below it, it is convenient for the user to pull the whole multi-layer rack 502 to move.

[0058] At least one first U-shaped plate 5023 is provided on the inner walls of the front and rear sides of the frame 5021, and the first U-shaped plates 5023 on the inner walls of the front and rear sides of the frame 5021 are distributed in one-to-one correspondence from top to bottom. Such a setting can place multiple trawl nets 503 simultaneously from top to bottom at one time. For example, 50 first U-shaped plates 5023 are provided on the inner walls of the front and rear sides of the frame 5021 from top to bottom, that is, 50 layers of trawl nets 503 can be placed. Each trawl net 503 receives two plates, so 100 plates can be received. At the same time, there is an equidistant interval of 15 mm between adjacent two layers of trawl nets 503, and leaving an interval can facilitate the clamping mechanism 505 to clamp the trawl nets 503.

[0059] The user pulls the frame 5021 through the handle 5024 to move through the universal wheels 5022, so that the whole multi-layer rack 502 can be conveniently moved, reducing the labor intensity of the staff.

[0060] The lifting mechanism 504 includes a base 5041 fixedly installed on the inner wall of the frame 501, a second driving motor 5042 fixedly installed on the top of the base 5041, a second lead screw 5043 fixedly installed on the output end of the second driving motor 5042, a second nut seat 5044 threadedly installed on the second lead screw 5043, a first lifting plate 5045 fixedly installed on the second nut seat 5044, and a support plate 5046 fixedly installed on the first lifting plate 5045.

[0061] A second slider 5047 is fixedly installed on the first lifting plate 5045, and a second slide rail 5048 matched with the second slider 5047 is fixedly installed on the base 5041. One end of the second slider 5047 away from the first lifting plate 5045 is slidably installed on the second slide rail 5048. With the cooperation of the second slider 5047 and the second slide rail 5048, it can play a guiding role in the lifting process of the first lifting plate 5045, making the movement of the first lifting plate 5045 more stable.

[0062] When the second driving motor 5042 drives the second lead screw 5043 to rotate clockwise, the second lead screw 5043 can drive the second nut seat 5044 to move upward. During the upward movement of the second nut seat 5044, it can drive the first lifting plate 5045 to move upward. During the upward movement of the first lifting plate 5045, it can drive the support plate 5046 to move upward. During the upward movement of the support plate 5046, it can drive the multi-layer rack 502 and the trawl nets 503 placed on the multi-layer rack 502 to move upward synchronously.

[0063] Similarly, when the second drive motor 5042 drives the second lead screw 5043 to rotate counterclockwise, it can drive the multi-layer rack 502 and the trawl net 503 placed on the multi-layer rack 502 to move downward synchronously;

[0064] Thus, under the action of the lifting mechanism 504, the lifting of the multi-layer rack 502 and the trawl net 503 placed on the multi-layer rack 502 is realized.

[0065] On one side of the inner cavity of the frame 501, a limiting mechanism 506 for limiting the multi-layer rack 502 is further provided. The limiting mechanism 506 includes a cylinder 5061 fixedly installed on the first lifting plate 5045, a limiting rod 5062 fixedly installed at the output end of the cylinder 5061, a limiting block 5063 fixedly installed on the inner bottom wall at the rear side of the frame 5021, and a limiting groove is formed in the middle of the limiting block 5063 and is matched with the limiting rod 5062;

[0066] A box door is hingedly installed on one side of the frame 501, and a door lock structure can be installed on the box door and the frame 501. The door lock structure is not the improvement point of this application, so the existing technology can be used for the door lock. Opening the box door can move out the trawl net 503 and the multi-layer rack 502 with full plates on one side of the inner cavity of the frame 501, then move a new multi-layer rack 502 into one side of the inner cavity of the frame 501, and then close the box door;

[0067] When the multi-layer rack 502 is moved into one side of the inner cavity of the frame 501, the bottom of the frame 5021 contacts the support plate 5046, the rear side of the frame 5021 contacts the first lifting plate 5045, and the limiting rod 5062 is located directly above the limiting groove formed in the limiting block 5063. At this time, the cylinder 5061 drives the limiting rod 5062 to move downward into the inside of the limiting groove. At this time, with the cooperation of the limiting rod 5062, the limiting groove and the limiting block 5063, the position of the multi-layer rack 502 can be fixed, so that the support plate 5046 can prevent the multi-layer rack 502 from displacing during the process of driving the multi-layer rack 502 to lift;

[0068] The clamping mechanism 505 includes a fourth drive motor fixedly installed on the other side of the inner cavity of the frame 501, a driving wheel 5051 fixedly installed on the output shaft of the fourth drive motor, a driven wheel 5052 rotatably installed on the frame 501, the same synchronous belt 5053 installed on the driving wheel 5051 and the driven wheel 5052, a transmission block fixedly installed on the synchronous belt 5053, a box body 5054 fixedly installed on the top of the transmission block, and a finger cylinder 5055 fixedly installed on the box body 5054;

[0069] A third slide rail 5012 is fixedly installed on the frame 501, a third slider 5056 is fixedly installed at the bottom of the box body 5054 and is matched with the third slide rail 5012, and the bottom of the third slider 5056 is slidably installed on the third slide rail 5012;

[0070] When the fourth driving motor drives the driving wheel 5051 to rotate clockwise, during the rotation of the driving wheel 5051, the driven wheel 5052 is driven to rotate synchronously through the synchronous belt 5053. During the rotation of the synchronous belt 5053, it can drive the transmission block to move towards the direction close to the multi-layer rack 502. During the movement of the transmission block, it can drive the box body 5054 to move towards the direction close to the multi-layer rack 502. During the movement of the box body 5054, it can drive the finger cylinder 5055 to move towards the multi-layer rack 502. When the finger cylinder 5055 moves to the position of the extraction trawl net 503, the clamping jaws on the finger cylinder 5055 clamp the trawl net 503. Then the fourth driving motor drives the driving wheel 5051 to rotate counterclockwise, so that the transmission block, the box body 5054 and the finger cylinder 5055 move away from the multi-layer rack 502. The trawl net 503 clamped by the finger cylinder 5055 extracts the trawl net 503 from the inside of the multi-layer rack 502. During the movement of the trawl net 503 towards the direction away from the multi-layer rack 502, its two sides slide inside the two second U-shaped plates 5011 respectively. After the trawl net 503 moves to the specified position, two plates are placed, and then the fourth driving motor drives the driving wheel 5051 to rotate clockwise so that the trawl net 503 moves inside the first U-shaped plate 5023 on the multi-layer rack 502. Finally, the fourth driving motor drives the driving wheel 5051 to rotate counterclockwise so that the transmission block, the box body 5054 and the finger cylinder 5055 move away from the multi-layer rack 502 and reset. At this time, the material receiving work of this layer of trawl net 503 is completed;

[0071] Then the lifting mechanism 504 drives the multi-layer rack 502 to rise one layer, so that the adjacent lower layer of trawl net 503 moves upward to the corresponding height position corresponding to the clamping mechanism 505, and then the above actions are repeated to complete the material receiving; this cycle works continuously until 50 layers of trawl nets 503 are filled with 100 sheets, and then a full material signal is given. The multi-layer rack 502 is manually pulled out, and then another multi-layer rack 502 is put in for material receiving;

[0072] The feeding mechanism 6 includes a fixing plate 601 fixedly installed inside the base 1, a third nut seat 602 fixedly installed at the middle position of the fixing plate 601, a third lead screw 603 threadedly installed inside the third nut seat 602, guide bushings 604 fixedly installed at the four corners of the fixing plate 601, guide rods 605 slidably installed inside the guide bushings 604, a motor mounting plate 606 fixedly installed at the bottom end of the guide rod 605, a feeding plate 607 fixedly installed at the top end of the guide rod 605, and a third driving motor 608 fixedly installed at the bottom of the motor mounting plate 606. The third lead screw 603 is fixedly installed on the output shaft of the third driving motor 608. The bottom end of the third lead screw 603 is rotatably installed at the top of the motor mounting plate 606 through a bearing, and the top end of the third lead screw 603 is rotatably installed at the bottom of the feeding plate 607 through a bearing; the feeding plate 607 is used for placing the stacked FPCs;

[0073] When the third drive motor 608 drives the third lead screw 603 to rotate clockwise, since the third nut seat 602 is fixedly installed on the fixed plate 601 and the fixed plate 601 is fixedly installed inside the base 1, when the third lead screw 603 rotates clockwise, the third lead screw 603 moves upward. When the third lead screw 603 moves upward, it drives the motor mounting plate 606 to move upward. During the upward movement of the motor mounting plate 606, it can drive the guide rod 605 to slide upward inside the guide bushing 604. During the upward sliding process of the guide rod 605, it can drive the material discharging plate 607 to slide upward;

[0074] Similarly, when the third drive motor 608 drives the third lead screw 603 to rotate counterclockwise, the material discharging plate 607 can be made to slide downward;

[0075] Therefore, the height of the material discharging plate 607 can be adjusted, so that the stacked FPC is at the loading height position when placed on the material discharging plate 607.

[0076] The transfer mechanism 4 includes two U-shaped brackets 401 fixedly installed on the top of the base 1, a third linear motor 402 fixedly installed on the top of the U-shaped bracket 401, a mounting bracket 403 driven by the third linear motor 402, a fourth linear motor 404 fixedly installed at the bottom of the mounting bracket 403, an electric slide table 405 driven by the fourth linear motor 404, a fixture mounting plate 406 driven by the electric slide table 405, and a suction cup 407 installed on the fixture mounting plate 406. The suction cup 407 uses a vacuum suction cup;

[0077] The stacked FPC is first placed on the loading plate 607. At the same time, under the action of two second linear motors 7, the two working platforms 3 are both moved to the loading position. Then, the fourth linear motor 404 drives the electric slide table 405, the fixture mounting plate 406, and the suction cup 407 to move in the direction close to the loading plate 607. When the suction cup 407 moves above the loading plate 607, the electric slide table 405 drives the suction cup 407 to move downward to adsorb the FPC. Then, the electric slide table 405 drives the suction cup 407 to move upward. Then, under the action of the third linear motor 402, it drives the mounting bracket 403, the fourth linear motor 404, the electric slide table 405, the suction cup 407, and the FPC to move above the left working platform 3. The electric slide table 405 drives the suction cup 407 and the FPC to move downward, so that the FPC is located on the working platform 3, and the adsorption of the FPC by the suction cup 407 is released. The electric slide table 405 moves upward to reset. Then, the second linear motor 7 drives the working platform 3 and the FPC to move to the dispensing station, that is, to the spray valve 210 on the left side of the dispensing mechanism 2. The spray valve 210 on the left side performs the dispensing action. At this time, under the cooperation of the third linear motor 402 and the fourth linear motor 404, it drives the electric slide table 405, the fixture mounting plate 406, and the suction cup 407 to move to the loading plate 607 to adsorb the FPC and then send the FPC to the right working platform 3. Then, the second linear motor 7 drives the right working platform 3 to move to the dispensing station, that is, to the spray valve 210 on the right side of the dispensing mechanism 2. The spray valve 210 on the right side performs the dispensing action;

[0078] After the spray valve 210 on the left side completes the dispensing action, it retreats to the loading position. Under the cooperation of the third linear motor 402 and the fourth linear motor 404, it drives the electric slide table 405, the fixture mounting plate 406, and the suction cup 407 to move to the working platform 3 at the loading position to adsorb the FPC after dispensing is completed, and then send the dispensed FPC to the drag net 503 of the material collector 5. Then, grasp the FPC to the left working platform 3 corresponding to the dispensing mechanism 2. The second linear motor 7 on the left drives the left working platform 3 to move to the spray valve 210 on the left side to perform the dispensing action. Then, after the spray valve 210 on the right side completes the dispensing action, it retreats to the loading position and sends a signal to the transfer mechanism 4. The transfer mechanism 4 grasps the FPC to the drag net 503 of the material collector 5, and then grasps the FPC to the right working platform 3 corresponding to the dispensing mechanism 2. The spray valve 210 on the right side performs the dispensing action, and so on, working continuously in a cycle.

[0079] An automatic dispensing method for an FPC flexible circuit board includes the following steps:

[0080] Step 1: Manually load a stacked FPC and place it on the loading mechanism 6. The loading mechanism 6 performs panoramic recognition and positioning. After starting the dispensing software through the controller, the loading mechanism 6 is ready and sends a signal to the transfer mechanism 4;

[0081] Step 2: The transfer mechanism 4 grabs the FPC to the left working platform 3 corresponding to the dispensing mechanism 2. The spray valve 210 on the left executes the dispensing action. Then the transfer mechanism 4 grabs another FPC to the right working platform 3 corresponding to the dispensing mechanism 2. The spray valve 210 on the right executes the dispensing action;

[0082] Step 3: After the spray valve 210 on the left completes the dispensing action, it retreats to the feeding position and gives a discharging signal to the transfer mechanism 4. The transfer mechanism 4 grabs the FPC onto the dragnet 503 of the receiving machine 5, then grabs the FPC to the left working platform 3 corresponding to the dispensing mechanism 2. The spray valve 210 on the left executes the dispensing action. Then after the spray valve 210 on the right completes the dispensing action, it retreats to the feeding position and gives a discharging signal to the transfer mechanism 4. The transfer mechanism 4 grabs the FPC onto the dragnet 503 of the receiving machine 5, then grabs the FPC to the right working platform 3 corresponding to the dispensing mechanism 2. The spray valve 210 on the right executes the dispensing action. This process repeats continuously;

[0083] Step 4: Two FPCs are received on one layer of the dragnet 503. After it is full, under the action of the lifting mechanism 504, the thousand-layer rack 502 is driven to rise one layer. The clamping mechanism 505 extracts another layer. This process repeats continuously until 100 are received. Then a full signal is given, and the thousand-layer rack 502 is manually pulled out and another thousand-layer rack 502 is put in.

[0084] In summary, by setting the transfer mechanism 4, the present invention can achieve automatic feeding. After the dispensing is completed, the transfer mechanism 4 of the same specification can also achieve automatic discharging. At the same time, through two independently operating working platforms 3 and two independently operating spray valves 210 used in cooperation with the two working platforms 3, the product can be continuously dispensed during the working process. Compared with the traditional dispensing device that can only dispense a single product at a time, the efficiency is improved.

[0085] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
