Description

Technical Field

[0001] This invention relates to the field of transportation technology, and more particularly to an FPC feeding mechanism. Background Technology

[0002] Flexible printed circuit (FPC) is also known as a flexible printed circuit board. FOG bonding equipment is used to press FPC sheets onto a glass substrate for further processing. FOG bonding equipment includes electronic paper preparation equipment, and the FPC feeding mechanism is a crucial component of the electronic paper preparation equipment.

[0003] The existing FPC feeding mechanism includes a loading mechanism, a picking mechanism, a transfer mechanism, and a unloading mechanism. The loading mechanism is used to place the tray containing the FPC sheet. The transfer mechanism uses a robot arm to transfer the entire tray of the loading mechanism to its own pallet. Then, the transfer mechanism moves the pallet and the FPC sheet on the pallet to the designated unloading position. Then, the picking mechanism uses a robot arm to pick up the FPC sheet on the pallet and transfer it to the unloading mechanism. The unloading mechanism then transfers the FPC sheet to the next process.

[0004] In the above process, the feeding mechanism must first wait for the transfer mechanism's pallet to place the empty pallet in the pallet recycling area before moving back to its original position to wait for feeding. Then, the transfer mechanism uses a robotic arm to transfer the pallet from the feeding mechanism to the transfer mechanism. This means that after the unloading mechanism finishes its work, the feeding mechanism still needs to wait for a period of time for the pallet to return to its original position before the transfer mechanism's robotic arm can transfer the pallet from the feeding mechanism to the pallet again. As a result, the feeding speed of the FPC feeding mechanism is slow, and the pause time between the feeding mechanism and the picking mechanism is long, leading to discontinuous picking actions of the picking mechanism and low production efficiency. Summary of the Invention

[0052] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0053] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0054] The invention also includes a control panel and a PLC control system, through which users can control the start and stop of the corresponding mechanism, the start and stop of the whole system, and emergency stop.

[0055] As one embodiment, refer to the appendix Figure 1-6The present invention proposes an FPC feeding mechanism, including a feeding mechanism 1, a conveying mechanism 2, a picking mechanism 3, and a tray recycling mechanism 4.

[0056] The discharge port of the feeding mechanism 1 is connected to the inlet of the transmission mechanism 2, and the discharge port of the transmission mechanism 2 passes through the picking mechanism 3 and is connected to the inlet of the tray recycling mechanism 4.

[0057] The feeding mechanism 1 is used to transfer the material tray containing the material to the picking mechanism 3 through the transmission mechanism 2. The picking mechanism 3 is used to pick up the material on the tray of its corresponding transmission mechanism 2 and transfer it to the unloading mechanism 5.

[0058] In this embodiment, FPC sheets are used as an example of the material. The material trays containing the material are stacked on the feeding mechanism 1. The material tray recycling mechanism 4 is used to collect the empty material trays after the FPC sheets have been taken out, and the empty material trays are stacked on the material tray recycling mechanism 4.

[0059] In this embodiment, compared with the FPC feeding mechanism in the prior art, the FPC feeding mechanism of the present invention optimizes the feeding mechanism 1 and the picking mechanism 3, making it faster and more continuous than the feeding mechanism in the prior art.

[0060] Specifically, the feeding mechanism 1 is first filled with trays containing FPC sheets. Then, the button to start the FPC feeding mechanism is pressed on the control panel. The PLC control system then controls the feeding mechanism 1 to continuously transfer the trays containing FPC sheets to the transfer mechanism 2. The PLC control system then controls the transfer mechanism 2 to sequentially transfer the trays to the picking mechanism 3. The picking mechanism 3 then continuously picks up the FPC sheets from the trays and transfers them to the unloading mechanism 5. Finally, the PLC control system controls the unloading mechanism 5 to transport the FPC sheets to the next process.

[0061] During this process, the feeding mechanism 1 will not transfer a new tray to the transfer mechanism 2 until the picking mechanism 3 has finished picking up the FPC sheet on the tray. Only after the picking mechanism 3 has finished picking up the FPC sheet will the transfer mechanism 2 move forward one tray distance, allowing the tray with the picked-up FPC sheet to move one tray distance until it reaches the tray recycling mechanism 4. At the same time, the feeding mechanism 1 will place a new tray containing FPC sheet onto the transfer mechanism 2. This forward movement of the transfer mechanism 2 facilitates the continuous transfer of trays containing FPC sheet to the picking mechanism 3, ensuring that the picking mechanism 3's picking action is smooth and uninterrupted, increasing the picking speed of the picking mechanism 3, and thus increasing the speed at which the FPC feeding mechanism can feed to the next process, thereby improving the production efficiency of the FPC feeding mechanism.

[0062] Among them, refer to the appendix Figure 1The feeding mechanism 1, the conveying mechanism 2, the picking mechanism 3, and the unloading mechanism 5 are each provided in two parts.

[0063] The opposite sides of the material tray recycling mechanism 4 are respectively connected to the outlet of a transmission mechanism 2, the inlet of each transmission mechanism 2 is respectively connected to the outlet of a feeding mechanism 1, and a picking mechanism 3 is provided on the transmission mechanism 2 between each feeding mechanism 1 and the corresponding material tray recycling mechanism 4.

[0064] Compared to the original single feeding structure and corresponding transmission, picking, and unloading mechanisms, this invention provides two feeding mechanisms 1 and corresponding transmission, picking, and unloading mechanisms 2, 3, and 5, which can further improve the feeding speed of the FPC feeding mechanism to the next process and further improve the production efficiency of the FPC feeding mechanism.

[0065] Furthermore, the feeding times of the two feeding mechanisms 1 should be staggered to prevent the corresponding transmission mechanism 2 from simultaneously transmitting empty material trays to the material tray recycling mechanism 4, causing collisions and affecting the normal operation of the FPC feeding mechanism.

[0066] Specifically, refer to the appendix Figure 2 The feeding mechanism 1 includes a storage bin 11, a lifting plate 12, a first lifting actuator 13, a insert plate 15, and a telescopic actuator 16. Both the first lifting actuator 13 and the telescopic actuator 16 are preferably motors.

[0067] The bottom of the storage bin 11 is provided with a lifting plate 12, the bottom of which is connected to the drive end of the first lifting actuator 13; the lifting plate 12 is provided with a plurality of holes 121, and each hole 121 is provided with a suction cup 14; wherein the suction cup 14 is a suction cup connected to an air passage (specifically, a suction cylinder or other suction device can be provided).

[0068] The lower part of the storage bin 11 is provided with inserts 15 on both sides perpendicular to the transmission direction of the transmission mechanism 2, and each insert 15 is connected to the drive end of one of the telescopic actuators 16.

[0069] The first lifting actuator 13 can drive the lifting plate 12 to move up and down within the storage bin 11; the suction cup 14 is used to adsorb the material trays on the last layer of the storage bin 11; the telescopic actuator 16 can drive the insert 15 to move telescopically toward the interior of the storage bin 11, and the insert 15 is used to engage and support the material trays inside the storage bin 11.

[0070] When the feeding mechanism 1 needs to place the tray containing FPC sheets onto the conveying mechanism 2, the PLC control system will control the first lifting actuator 13 to move the lifting plate 12 upward and lift the stacked trays in the storage bin 11. At the same time, the telescopic actuator 16 will control the insert 15 to retract from both sides of the storage bin 11 (i.e., the insert 15 will no longer engage with the trays in the storage bin 11). Then, the suction cup 14 will firmly adhere to the tray of the last layer. Then, the first lifting actuator 13 will descend by the height of one tray, and then the telescopic actuator... 16. Then, the insert 15 extends from both sides of the storage bin 11, so that the insert 15 is inserted between the last and second-to-last material trays, so that the second-to-last and above material trays are supported by the insert 15. Then, the first lifting actuator 13 descends to or below the conveying surface of the transmission mechanism 2. The last material tray will follow the first lifting actuator 13 down until it is placed on the transmission mechanism 2. Then, the suction cup 14 no longer holds the last material tray, so that when the transmission mechanism 2 moves forward, it can drive the material tray to the picking mechanism 3.

[0071] The transmission mechanism 2 can be any one of a transmission belt, a transmission roller, and a transmission mesh chain. In this embodiment, the transmission mechanism 2 is preferably a transmission belt.

[0072] Among them, refer to the appendix Figure 3 The picking mechanism 3 includes a four-axis transmission device 31 and an adsorption device 32; the driving end of the four-axis transmission device 31 is connected to the adsorption device 32; wherein the adsorption device 32 is preferably a suction cup connected to the air passage (specifically, an air suction cylinder or other air suction device can be set), and the FPC sheet is picked up by adsorbing the suction cup.

[0073] The four-axis transmission device 31 is used to control the adsorption device 32 to perform four-axis motion, so as to pick up the material on the transmission mechanism 2 and transfer it to the feeding mechanism 5.

[0074] In this way, the picking mechanism 3 can control the adsorption device 32 to perform four-axis motion to pick up FPC sheets from different positions on the same tray and place them onto the unloading mechanism 5.

[0075] Specifically, refer to the appendix Figure 3 The four-axis transmission device 31 includes an X-axis guide rail 312, a Y-axis guide rail 313, a Z-axis guide rail 314, and a Q-axis actuator 315; the Q-axis actuator 315 is preferably a motor.

[0076] A first base 311 is provided on one side of the transmission mechanism 2 located between the feeding mechanism 1 and the material tray recycling mechanism 4, and an X-axis guide rail 312 is horizontally provided on the first base 311.

[0077] The Y-axis guide rail 313 is vertically connected to the X-axis guide rail 312 and moves horizontally along the X-axis guide rail 312; the Z-axis guide rail 314 is connected to the Y-axis guide rail 313 and moves along the Y-axis guide rail 313; the Q-axis actuator 315 is connected to the Z-axis guide rail 314 and moves vertically along the Z-axis guide rail 314; the adsorption device 32 is connected to the drive end of the Q-axis actuator 315 and rotates around the axis of the Q-axis actuator 315.

[0078] When the picking mechanism 3 is running, the PLC control system first controls the Y-axis guide rail 313 to move horizontally along the X-axis guide rail 312, then controls the Z-axis guide rail 314 to move horizontally on the Y-axis guide rail 313, and then controls the Q-axis actuator 315 to move vertically on the Z-axis guide rail 314, so that the adsorption device 32 approaches or even contacts the FPC sheet on the tray. Then the adsorption device 32 adsorbs the FPC sheet, and the PLC control system can control the adsorption device 32 to rotate around the axis of the Q-axis actuator 315 (i.e., move in the Q-axis direction). Therefore, the PLC control system can control the adsorption device 32 to perform four-axis movements of X, Y, Z, and Q to achieve the adsorption device 32 to accurately adsorb the FPC sheet and pick it up to the unloading mechanism 5.

[0079] Of course, the horizontal movement of the Z-axis guide rail 314 on the Y-axis guide rail 313, the horizontal movement of the Z-axis guide rail 314 on the Y-axis guide rail 313, and the vertical movement of the Q-axis actuator 315 on the Z-axis guide rail 314 are all achieved by motors.

[0080] Among them, refer to the appendix Figure 4 The material tray recycling mechanism 4 includes a cuboid recycling tray 41. The top of the two side walls of the recycling tray 41 along the transmission direction of the transmission mechanism 2 are provided with guide components 42, which include a parallel plate 421 and an inclined plate 422.

[0081] The discharge port of the transmission mechanism 2 is connected to one end of the parallel plate 421, and the parallel plate 421 is flush with the transmission mechanism 2. The other end of the parallel plate 421 is connected to an inclined plate 422, which is inclined toward the center of the recycling tray 41.

[0082] When the conveying mechanism 2 transports the empty material tray to the recycling tray 41 for stacking, the empty material tray will first pass through the parallel plate 421, and then slide along the inclined plate 422 into the recycling tray 41 for stacking. This can limit the movement direction of the empty material tray and ensure the direction in which the empty material tray falls.

[0083] Among them, refer to the appendix Figure 4A sensor 43 is provided on the upper part of one side wall of the recycling tray 41, which is perpendicular to the transmission direction of the transmission mechanism 2. The sensor 43 is used to detect the position of the empty tray. When the sensor 43 detects that the recycling tray 41 has fallen into the first empty tray, it sends a feedback electrical signal to the PLC control system. After receiving the signal, the PLC control system will control the corresponding structure to perform the corresponding movement.

[0084] Specifically, the material tray recycling mechanism 4 further includes a second lifting actuator (not shown, the same throughout), the drive end of which is connected to the bottom wall of the recycling material tray 41; the second lifting actuator is used to drive the recycling material tray 41 to perform lifting movements.

[0085] The second lifting actuator is located below the recycling tray hopper 41. When there is no empty tray in the recycling tray hopper 41, the PLC control system will control the second lifting actuator to drive the recycling tray hopper 41 to move upward. In this way, when the transmission mechanism 2 transmits the first empty tray to the recycling tray hopper 41, the first empty tray will not jam. Jamming includes situations where the empty tray is irregularly placed, not horizontally placed, which is not conducive to the stacking of subsequent empty trays. When the sensor 43 of the recycling tray hopper 41 detects that an empty tray has fallen into the recycling tray hopper 41, the sensor 43 will send a first feedback electrical signal to the PLC control system. After receiving the signal, the PLC control system will control the second lifting actuator to drive the recycling tray hopper 41 to move downward, i.e., reset.

[0086] When the sensing sensor 43 detects that the empty material tray transmitted by the transmission mechanism 2 is suspended above the recycling tray 41 and does not fall, the sensing sensor 43 will send a second feedback electrical signal to the PLC control system again. After receiving the signal, the PLC control system will control the second lifting actuator to drive the recycling tray 41 to move upward, so that the suspended material tray falls correctly into the recycling tray 41. Then, the PLC control system will control the second lifting actuator to reset the recycling tray 41.

[0087] Among them, refer to the appendix Figure 5 Above the picking mechanism 3, there is also a camera component 6, which is used to capture images of the material on the tray inside the picking mechanism 3 and upload them to the host computer.

[0088] Because the FPC sheets on the tray will undergo slight displacement during the transfer process between the feeding mechanism 1 and the conveying mechanism 2, resulting in different placement positions of the FPC sheets on the tray, when the picking mechanism 3 is working, the PLC control system will simultaneously activate the camera component 6 to acquire the image position information of the FPC sheets in the tray and upload it to the host computer. Then, the host computer processes the received image position information and sends a control signal to the PLC control system. The PLC control system will adjust the position of the adsorption device 32 accordingly based on the received control signal, so that the adsorption device 32 can accurately adsorb the corresponding FPC sheet and then pick it up onto the unloading mechanism 5.

[0089] Specifically, refer to the appendix Figure 5 The camera assembly 6 includes a second base 61, a slide rail 62, a slider 63, and a camera 64.

[0090] The second base 61 is vertically provided with a slide rail 62, which is slidably connected to the sliding member 63. A camera 64 is mounted on the sliding member 63, and the lens of the camera 64 faces the transmission mechanism 2.

[0091] Before the FPC feeding mechanism is started, the user adjusts the position of the camera component 6 to ensure that the camera 64 of the camera component 6 can capture image information of all positions of the FPC sheet on the entire tray.

[0092] The adjustment method for camera component 6 is as follows:

[0093] The slider 63 is moved up and down along the slide rail 62 to adjust the distance between the camera 64 and the transmission mechanism 2. After adjustment, the slider 63 is prevented from moving downward during the operation of the FPC feeding mechanism by a limiting device, which would affect the picking efficiency of the picking mechanism 3 and reduce the production efficiency of the FPC feeding mechanism. This limiting device is existing technology and will not be described in detail here.

[0094] Among them, refer to the appendix Figure 6 The unloading mechanism 5 includes an unloading guide rail 51, on which a support platform 52 is slidably connected. First, the PLC control system controls the support platform 52 to slide along the unloading guide rail 51 to the picking mechanism 3 via a motor. Then, the picking mechanism 3 picks up the FPC sheet and places it on the support platform 52. Finally, the support platform 52 and the FPC sheet it carries are controlled to move along the unloading guide rail 51 to the next process.

[0095] The usage process of the FPC feeding mechanism of this invention:

[0096] First, the material storage bin 11 of the feeding mechanism 1 is filled with trays containing FPC sheets. Then, the start button is pressed on the control panel. The PLC control system then controls the feeding mechanism 1 to place the trays containing FPC sheets onto the transmission mechanism 2. The transmission mechanism 2 then transmits the trays containing FPC sheets to the bottom of the picking mechanism 3. The camera component 6 is then controlled to acquire the image position information of the FPC sheets in the tray and upload it to the host computer. The host computer then processes the received image position information and sends a control signal to the PLC control system. The PLC control system will adjust the position of the adsorption device 32 according to the received control signal, so that the adsorption device 32 can accurately adsorb the FPC sheets and pick them up to the unloading mechanism 5.

[0097] After the picking mechanism 3 has picked up all the FPC sheets from the tray, the PLC control system will control the transmission mechanism 2 to move one tray distance so that the next tray containing FPC sheets can be transferred to the picking mechanism 3. The empty tray after picking up the FPC sheets will move forward one tray distance until the empty tray falls into the recycling tray 41.

[0098] When the material trays in the storage bin 11 are used up, the corresponding button can be pressed on the control panel to stop the PLC control system from controlling the feeding mechanism 1 to stop working. However, the transmission mechanism 2, the picking mechanism 3, and the camera component 6 will continue to work. After the user fills the storage bin 11 with material trays containing FPC sheets again, the corresponding button can be pressed on the control panel to start the feeding mechanism 1 to start working again.

[0099] Obviously, the embodiments described above are merely some embodiments of the present invention, not all embodiments.

The present invention can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention.
