Description

Technical Field

[0001] This utility model belongs to the field of FPC board production technology, specifically relating to an automatic dispensing equipment for FPC flexible circuit boards. Background Technology

[0002] Flexible printed circuit boards (FPCs) require dispensing using spray valves during production. However, some existing spray valves are installed separately, and each valve can only dispense adhesive onto one product at a time. This results in slow dispensing speeds when dealing with mass production. Furthermore, in existing technologies, loading and unloading of materials during the dispensing process are sometimes done manually, leading to low production efficiency. Utility Model Content

[0021] An automated dispensing method for FPC flexible circuit boards includes the following steps:

[0022] Step 1: Manually load a stacked FPC into the feeding mechanism. The feeding mechanism is equipped with panoramic recognition and positioning. After the dispensing software is started via the controller, the feeding mechanism is ready and sends a signal to the transfer mechanism.

[0023] Step 2: The transfer mechanism picks up the FPC and places it on the left working platform corresponding to the dispensing mechanism. The spray valve on the left performs the dispensing action. The transfer mechanism then picks up another FPC and places it on the right working platform corresponding to the dispensing mechanism. The spray valve on the right performs the dispensing action.

[0024] Step 3: After the left spray valve completes the dispensing action, it retracts to the loading position and sends a signal to the transfer mechanism to unload the FPC. The transfer mechanism grabs the FPC onto the receiving machine's trolley, and then grabs the FPC onto the left working platform corresponding to the dispensing mechanism. The left spray valve then performs the dispensing action. After the right spray valve completes the dispensing action, it retracts to the loading position and sends a signal to the transfer mechanism to unload the FPC. The transfer mechanism grabs the FPC onto the receiving machine's trolley, and then grabs the FPC onto the right working platform corresponding to the dispensing mechanism. The right spray valve then performs the dispensing action. This cycle continues continuously.

[0025] Step 4: Two FPCs are collected on each layer of the drag net. Once full, the lifting mechanism raises the multilayer rack by one layer, and the clamping mechanism pulls out another layer. This cycle continues until the rack is full. Then, a full material signal is given, and the multilayer rack is manually pulled out and another multilayer rack is placed in.

[0026] (3) Beneficial effects

[0028] This invention enables automated material feeding through a transfer mechanism. After dispensing is completed, the same-specification transfer mechanism can also achieve automated material unloading. Furthermore, this invention utilizes two independently operating work platforms and two independently operating spray valves that work in conjunction with these platforms, allowing for continuous dispensing of products during operation. Compared to traditional dispensing devices that can only dispense one product at a time, this significantly improves efficiency. Attached Figure Description

Detailed Implementation

[0043] This specific embodiment is an automatic dispensing device for FPC flexible circuit boards, and its structural schematic diagram is shown below. Figures 1-13 As shown, the dispensing equipment includes a base 1, a dispensing mechanism 2 installed on the base 1, two independently working work platforms 3 installed on the base 1, a transfer mechanism 4 for transferring materials installed on the base 1, a receiving machine 5 set on one side of the base 1, a feeding mechanism 6 installed on the base 1, and two second linear motors 7 for driving the work platforms 3 to move on the base 1.

[0044] The dispensing mechanism 2 includes two mounting brackets 201 fixedly mounted on the base 1, a first linear motor 202 fixedly mounted on the top of the two mounting brackets 201, two first sliding blocks 203 driven by the first linear motor 202, a housing 204 fixedly mounted on the side of the first sliding block 203 away from the first linear motor 202, a first drive motor 205 fixedly mounted on the top of the housing 204, a first lead screw 206 fixedly mounted on the output end of the first drive motor 205, a first nut seat 207 threaded onto the first lead screw 206, an L-shaped connecting plate 208 fixedly mounted on the first nut seat 207, a mounting plate 209 fixedly mounted on the L-shaped connecting plate 208, and a spray valve 210 fixedly mounted 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 drive motor 205 drives the first lead screw 206 to rotate clockwise, the first lead screw 206 can drive the first nut seat 207 threadedly installed with it to move downward during the rotation. The first nut seat 207 can drive the L-shaped connecting plate 208 fixedly installed with it to move downward during the downward movement. The L-shaped connecting plate 208 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 drive motor 205 drives the first lead screw 206 to rotate counterclockwise, it can make the mounting plate 209 and the spray valve 210 move upward synchronously.

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

[0048] Each first nut seat 207 has two L-shaped connecting plates 208, and the two L-shaped connecting plates 208 are symmetrically installed on both sides of the first nut seat 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 seat 207 are respectively fixedly connected to the two ends of the mounting plate 209. Under the action of this gap, the L-shaped connecting plates 208 will not contact the housing 204 during movement, thereby enabling the movement of the L-shaped connecting plates 208 and the mounting plate 209.

[0049] The bottom end of the first lead screw 206 is rotatably mounted on the inner bottom wall of the housing 204 via a bearing, and the housing 204 provides support for the first lead screw 206.

[0050] Two L-shaped connecting plates 208 are fixedly mounted with first sliders 211 on the side near the first linear motor 202. Two first slide rails 212 that cooperate with the first sliders 211 are fixedly mounted on the inner wall of the side of the housing 204 near the first linear motor 202. The two first sliders 211 are slidably mounted on the two first slide rails 212 respectively.

[0051] With the cooperation of the first slider 211 and the first slide rail 212, the movement of the L-shaped connecting plate 208 can be guided, making the L-shaped connecting plate 208 more stable during movement, thereby making the mounting plate 209 and the spray valve 210 more stable during movement.

[0052] The first linear motor 202 can drive the spray valve 210 to move in the X-axis direction, and the second linear motor 7 can drive the working platform 3 to move in the Y-axis direction. Furthermore, the spray valve 210 can move in the Z-axis direction with the cooperation of the first drive 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 receiving machine 5 includes a frame 501, a multi-layer rack 502 disposed on one side of the inner cavity of the frame 501, a drag net 503 placed on the multi-layer rack 502, a lifting mechanism 504 disposed on one side of the inner cavity of the frame 501 for lifting the multi-layer rack 502 and the drag net 503, and a clamping mechanism 505 disposed on the frame 501 for clamping the drag net 503;

[0054] The shelf 502 includes a frame 5021, casters 5022 installed at the four corners of the bottom of the frame 5021, a first U-shaped plate 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] A second U-shaped plate 5011 is symmetrically fixedly installed on the frame 501. An L-shaped plate 5013 is fixedly installed on the side of the two second U-shaped plates 5011 that is far apart from each other. The end of the L-shaped plate 5013 that is far away from the second U-shaped plate 5011 is fixedly installed on the frame 501. The side of the two second U-shaped plates 5011 that is close to each other can slide to place the trawl net 503. That is, when the clamping mechanism 505 pulls the trawl net 503 from the multi-layer rack 502, the two sides of the trawl net 503 slide inside the two second U-shaped plates 5011 respectively. When the trawl net 503 is completely pulled out from the multi-layer rack 502, the two sides of the trawl net 503 are located inside the two second U-shaped plates 5011 respectively.

[0056] The caster wheel 5022 can be a self-locking caster wheel, which makes the entire shelf 502 easy to move.

[0057] The handles 5024 are positioned on the left and right sides to make it easy for the user to pull the entire shelf 502 and move it.

[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 one-to-one from top to bottom. This arrangement allows multiple layers of trawl nets 503 to be placed at the same time from top to bottom. For example, if there are 50 first U-shaped plates 5023 on the inner walls of the front and rear sides of the frame 5021 from top to bottom, 50 layers of trawl nets 503 can be placed. Each trawl net 503 holds two plates, so 100 plates can be held. At the same time, the two adjacent layers of trawl nets 503 are equally spaced by 15mm to facilitate the clamping mechanism 505 to clamp the trawl nets 503.

[0059] Users can move the frame 5021 by pulling the handle 5024 and moving it via the casters 5022, which makes the entire shelf 502 easy to move and reduces 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 drive 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 drive 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 that cooperates with the second slider 5047 is fixedly installed on the base 5041. The 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, the first lifting plate 5045 can be guided during the lifting process, making the movement of the first lifting plate 5045 more stable.

[0062] When the second drive 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, the second nut seat 5044 can drive the first lifting plate 5045 to move upward. During the upward movement, the first lifting plate 5045 can drive the support plate 5046 to move upward. During the upward movement, the support plate 5046 can drive the multi-layer rack 502 and the trawler 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 drag net 503 placed on the multi-layer rack 502 to move downward synchronously.

[0064] Thus, the lifting mechanism 504 enables the lifting and lowering of the multi-layer rack 502 and the trawler 503 placed on the multi-layer rack 502.

[0065] A limiting mechanism 506 for limiting the shelf 502 is also provided on one side of the inner cavity of the frame 501. The limiting mechanism 506 includes a cylinder 5061 fixedly installed on the first lifting plate 5045, a limiting rod 5062 fixedly installed on the output end of the cylinder 5061, a limiting block 5063 fixedly installed on the inner bottom wall of the rear side of the frame 5021, and a limiting groove that cooperates with the limiting rod 5062 is opened in the middle of the limiting block 5063.

[0066] A door is hinged to one side of the frame 501. A door lock structure can be installed on the door and the frame 501. The door lock structure is not an improvement of this application. Therefore, the existing technology can be used for the door lock. Opening the door can remove the trolley 503 and the multi-layer rack 502 that are filled with plates on one side of the inner cavity of the frame 501. Then, a new multi-layer rack 502 is moved into one side of the inner cavity of the frame 501. Then the door is closed.

[0067] When the multi-layer rack 502 moves 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 opened by the limiting block 5063. At this time, the cylinder 5061 drives the limiting rod 5062 to move downward into the interior of the limiting groove. 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. In this way, the support plate 5046 can prevent the multi-layer rack 502 from shifting during the lifting and lowering process.

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

[0069] A third slide rail 5012 is fixedly installed on the frame 501, and a third slider 5056 that cooperates with the third slide rail 5012 is fixedly installed on the bottom of the housing 5054. The bottom of the third slider 5056 is slidably installed on the third slide rail 5012.

[0070] When the fourth drive motor drives the drive wheel 5051 to rotate clockwise, the drive wheel 5051 drives the driven wheel 5052 to rotate synchronously via the synchronous belt 5053. The synchronous belt 5053, during its rotation, drives the transmission block to move closer to the shelf 502. The transmission block, in turn, drives the housing 5054 to move closer to the shelf 502. The housing 5054, in turn, drives the finger cylinder 5055 to move towards the shelf 502. When the finger cylinder 5055 reaches the position for pulling out the netting 503, the grippers on the finger cylinder 5055 clamp the netting 503. Then, the fourth drive motor drives the drive wheel 5051 to rotate counterclockwise, causing the transmission block, housing 5054, and finger cylinder 5055 to move. 5. Move away from the multi-layer rack 502. The drag net 503 held by the finger cylinder 5055 is pulled out from the inside of the multi-layer rack 502. During the movement away from the multi-layer rack 502, the drag net 503 slides inside the two second U-shaped plates 5011 on both sides. After the drag net 503 moves to the designated position, two plates are placed. Then, the fourth drive motor drives the drive wheel 5051 to rotate clockwise, so that the drag net 503 moves into the inside of the first U-shaped plate 5023 on the multi-layer rack 502. Finally, the fourth drive motor drives the drive wheel 5051 to rotate counterclockwise, so that the transmission block, the box 5054 and the finger cylinder 5055 move away from the multi-layer rack 502 and reset. At this time, the material collection work of the drag net 503 of this layer is completed.

[0071] Then, the lifting mechanism 504 drives the multilayer rack 502 to rise one layer, so that the adjacent next layer of trawl 503 moves upward to the height position corresponding to the clamping mechanism 505. Then, the above action is repeated to complete the material collection. This cycle continues until the 50-layer trawl 503 has collected 100 sheets. Then, a full material signal is given, and the multilayer rack 502 is manually pulled out and another multilayer rack 502 is put in for material collection.

[0072] The feeding mechanism 6 includes a fixed plate 601 fixedly installed inside the base 1, a third nut seat 602 fixedly installed in the middle of the fixed 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 fixed plate 601, guide rods 605 slidably installed inside the guide bushings 604, a motor mounting plate 606 fixedly installed at the bottom of the guide rods 605, a feeding plate 607 fixedly installed at the top of the guide rods 605, and a third drive 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 drive motor 608. The bottom end of the third lead screw 603 is rotatably installed on the top of the motor mounting plate 606 through a bearing, and the top end of the third lead screw 603 is rotatably installed on the bottom of the feeding plate 607 through a bearing. The feeding plate 607 is used to place 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, the third lead screw 603 moves upward when it rotates clockwise. 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 of the guide rod 605, it can drive the feeding plate 607 to slide upward.

[0074] Similarly, when the third drive motor 608 drives the third lead screw 603 to rotate counterclockwise, the feeding plate 607 can slide downward.

[0075] Therefore, the height of the feeding plate 607 can be adjusted so that the stacked FPCs are at the feeding height position when the feeding plate 607 is placed.

[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 brackets 401, a mounting bracket 403 driven by the third linear motor 402, a fourth linear motor 404 fixedly installed on the bottom of the mounting bracket 403, an electric slide 405 driven by the fourth linear motor 404, a clamp mounting plate 406 driven by the electric slide 405, and a suction cup 407 installed on the clamp mounting plate 406. The suction cup 407 is a vacuum suction cup.

[0077] The stacked FPCs are first placed on the feeding plate 607. Simultaneously, under the action of two second linear motors 7, both working platforms 3 are moved to the loading position. Then, the fourth linear motor 404 drives the electric slide 405, the clamp mounting plate 406, and the suction cup 407 to move closer to the feeding plate 607. When the suction cup 407 moves above the feeding plate 607, the electric slide 405 drives the suction cup 407 downwards to pick up the FPC. Then, the electric slide 405 drives the suction cup 407 upwards. Then, under the action of the third linear motor 402, the mounting bracket 403, the fourth linear motor 404, the electric slide 405, the suction cup 407, and the FPC are moved to above the left working platform 3. The electric slide 405 drives the suction cup 407 and the FPC... C moves downward, placing the FPC on the working platform 3 and releasing the suction cup 407 from adsorbing the FPC. The electric slide 405 moves upward to reset, and then the second linear motor 7 drives the working platform 3 and the FPC to the dispensing station, that is, the spray valve 210 on the left side of the dispensing mechanism 2. The left spray valve 210 performs the dispensing action. At this time, with the cooperation of the third linear motor 402 and the fourth linear motor 404, the electric slide 405, the clamp mounting plate 406 and the suction cup 407 are driven to move to the feeding plate 607 to adsorb the FPC and then send the FPC to the working platform 3 on the right side. Then the second linear motor 7 drives the working platform 3 on the right side to the dispensing station, that is, the spray valve 210 on the right side of the dispensing mechanism 2. The right spray valve 210 performs the dispensing action.

[0078] After the left spray valve 210 completes the dispensing action, it retracts to the loading position. With the cooperation of the third linear motor 402 and the fourth linear motor 404, it drives the electric slide table 405, the clamp mounting plate 406, and the suction cup 407 to move to the working platform 3 at the loading position to pick up the FPC after dispensing. Then, the FPC after dispensing is sent to the trolley 503 of the receiving machine 5. Next, the FPC is grabbed onto 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 left spray valve 210 to perform the dispensing action. Then, after the right spray valve 210 completes the dispensing action, it retracts to the loading position and sends a feeding signal to the transfer mechanism 4. The transfer mechanism 4 grabs the FPC onto the trolley 503 of the receiving machine 5. Then, the FPC is grabbed onto the right working platform 3 corresponding to the dispensing mechanism 2. The right spray valve 210 performs the dispensing action. This cycle continues continuously.

[0079] An automated dispensing method for FPC flexible circuit boards includes the following steps:

[0080] Step 1: Manually load a stacked FPC and place it on the loading mechanism 6. The loading mechanism 6 is equipped with panoramic recognition and positioning. After the dispensing software is started 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 onto the left working platform 3 corresponding to the dispensing mechanism 2, and the spray valve 210 on the left performs the dispensing action. The transfer mechanism 4 then grabs another FPC onto the right working platform 3 corresponding to the dispensing mechanism 2, and the spray valve 210 on the right performs the dispensing action.

[0082] Step 3: After the left spray valve 210 completes the dispensing action, it retracts to the loading position and sends a dispensing signal to the transfer mechanism 4. The transfer mechanism 4 grabs the FPC onto the trawl 503 of the receiving machine 5, and then grabs the FPC onto the left working platform 3 corresponding to the dispensing mechanism 2. The left spray valve 210 performs the dispensing action. Then, after the right spray valve 210 completes the dispensing action, it retracts to the loading position and sends a dispensing signal to the transfer mechanism 4. The transfer mechanism 4 grabs the FPC onto the trawl 503 of the receiving machine 5, and then grabs the FPC onto the right working platform 3 corresponding to the dispensing mechanism 2. The right spray valve 210 performs the dispensing action. This cycle continues continuously.

[0083] Step 4: Two FPCs are collected on the first layer of the drag net 503. After the net is full, the lifting mechanism 504 drives the multilayer rack 502 to rise one layer, and the clamping mechanism 505 pulls out another layer. This cycle continues until 100 sheets are collected. Then, a full material signal is given, and the multilayer rack 502 is manually pulled out and another multilayer rack 502 is put in.

[0084] In summary, this utility model can achieve automated feeding by setting up a transfer mechanism 4. After the dispensing is completed, the transfer mechanism 4 of the same specification can also achieve automated unloading. At the same time, this utility model can continuously dispense products during the operation by using two independently working working platforms 3 and two independently working spray valves 210 that cooperate with the two working platforms 3. Compared with the traditional dispensing device, which can only dispense one product at a time, the efficiency is improved.

[0085] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
