Description

Technical Field

[0001] This invention relates to the field of electromagnetic diaphragm assembly mechanism technology, and in particular to an electromagnetic diaphragm assembly mechanism and method. Background Technology

[0002] As the quality requirements for smartphones and in-vehicle systems increase, so do the manufacturing process requirements. Electromagnetic films have been added to the backlights of smartphones and in-vehicle systems. Their core function is to effectively block electromagnetic waves generated by the internal circuitry of the phone or system, thereby improving the accuracy of handwriting, enabling more efficient screen operation, and effectively carrying away some heat to provide auxiliary heat dissipation, thus ensuring the stability of the screen display. Products with rolled edges on both ends of the iron frame can only be assembled manually in the traditional way.

[0003] Traditional assembly methods typically use iron frames with only four side walls. Modern machines can vertically attach and align the diaphragm within the frame. However, for products with rolled edges at both ends, this angled insertion method is insufficient. Currently, manual assembly remains the most common method for iron frame products with rolled edges. Operators can adjust the diaphragm's position and angle to ensure proper placement within the frame, avoiding positional errors and assembly difficulties. However, manual assembly is inefficient, far slower than automated equipment, and cannot meet the demands of large-scale production. Furthermore, it is susceptible to fluctuations in assembly accuracy and adhesion quality due to operator fatigue, skill level, and mood, making it difficult to guarantee product yield. Therefore, an electromagnetic diaphragm assembly mechanism and method are needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electromagnetic diaphragm assembly mechanism includes a processing base. From left to right, the top of the processing base is provided with a feeding part, a bearing part, a transfer part and a support part. An adjustment part is provided near the support part at the top of the processing base. The modular design realizes the automation and integration of the assembly process and ensures that each process is closely connected.

[0007] The supporting part includes a processing table fixed to the surface of the processing base, and a transfer platform is provided on the side of the processing table. The transfer platform is fixedly installed on the surface of the processing base, and an electromagnetic membrane is placed and installed on the top of the transfer platform. The structure of the supporting part, including the processing table and the transfer platform, is used to place and temporarily store the electromagnetic membrane. Its function is to provide a stable working platform and ensure that the electromagnetic membrane is fixed in position during processing and transfer.

[0008] The transfer section includes a five-axis robotic arm mounted on the surface of the processing base. A second telescopic cylinder is installed at the top arm of the five-axis robotic arm, and an adsorption component is installed after the piston rod of the second telescopic cylinder passes through the arm of the five-axis robotic arm. The electromagnetic membrane is accurately transferred and positioned by the multi-axis robotic arm. Combined with the control of the lifting and lowering of the adsorption component by the second telescopic cylinder, the membrane can be moved flexibly and accurately aligned with the iron frame, thereby improving the assembly accuracy.

[0009] The supporting part includes two opposing side support plates fixed to the surface of the processing base. The two side support plates are connected and fixed to each other by an inner fixing plate. A frame plate is connected to the top of the side support plate. An iron frame is placed on the surface of the frame plate. A high-definition camera supplementary lighting module is set inside the frame plate.

[0010] Preferably, the feeding part includes a plate A fixed to the surface of the processing base. A threaded screw A is rotatably installed inside the plate A, and one end of the threaded screw A passes through the plate A and is fixedly connected to the shaft end of the micro motor A. The micro motor A is installed on the surface of the processing base. A sleeve block A is threadedly fitted on the surface of the threaded screw A, and a first telescopic cylinder is provided on the side wall of the upright end of the sleeve block A. The piston rod end of the first telescopic cylinder is connected to a robot arm, and the top of the robot arm is provided with two cantilever arms. The bottom ends of the two cantilever arms are provided with several suction nozzles A. The top of the suction nozzles A can be connected to a vacuum generator to facilitate the adsorption of the electromagnetic membrane through the suction nozzles A.

[0011] Preferably, the electromagnetic membrane is provided with a tail plug end on its side, and the tail plug end is inserted into the inner wall of the iron frame through a through groove. The left side of the electromagnetic membrane is snapped against the left side of the inner wall of the iron frame.

The tail plug end on the right side of the electromagnetic membrane can be inserted into the through groove of the iron frame during installation to achieve positioning of the electromagnetic membrane.

[0012] Preferably, the adsorption component includes a main suction cylinder that connects to the end of the piston rod of the second telescopic cylinder. A suction nozzle B is provided at the bottom of the main suction cylinder. A first auxiliary suction cylinder and a second auxiliary suction cylinder are respectively provided on the left and right sides of the main suction cylinder. A sliding plate is provided at the bottom of the shaft end of both the first auxiliary suction cylinder and the second auxiliary suction cylinder. A suction nozzle C is provided below the sliding plate. By cooperating with the main suction cylinder, the first auxiliary suction cylinder and the second auxiliary suction cylinder, two additional adsorption structures are provided compared with the traditional structure. The two suction nozzles C and the suction nozzle B can cooperate to adsorb the electromagnetic membrane, which facilitates local adjustment of the electromagnetic membrane.

[0013] Preferably, the inner side of the slide plate is provided with a guide groove, and the outer sides of the second auxiliary suction cylinder and the first auxiliary suction cylinder are provided with guide strip ends. The guide strips of the first auxiliary suction cylinder and the second auxiliary suction cylinder are slidably connected to the guide groove of the slide plate. When the slide plate moves on the guide strip ends on the surfaces of the second auxiliary suction cylinder and the first auxiliary suction cylinder, the stability of the slide plate during vertical movement can be ensured, and the slide plate is prevented from shaking or deviating during the movement of the guide strip ends on the surfaces of the second auxiliary suction cylinder and the first auxiliary suction cylinder, so that the suction nozzle C can move down stably to adsorb the two sides of the top of the electromagnetic membrane.

[0014] Preferably, the outer side of the slide plate is connected to a side frame plate. The vertical cross-section of the side frame plate is an inverted L-shaped structure. The horizontal end of the side frame plate is fitted with an upper and lower adjustment bolt through a through hole. The shaft end of the upper and lower adjustment bolt is inserted into the top of the second auxiliary suction cylinder or the first auxiliary suction cylinder through a threaded hole. By rotating the upper and lower adjustment bolt, the side frame plate is pressed down, causing the side frame plate to move the slide plate down the surface of the second auxiliary suction cylinder, thereby pushing and changing the position of the suction nozzle C.

[0015] Preferably, the adjustment part includes a bracket fixed to the top of the processing base. A plate base B is connected to the top of the bracket. A threaded screw B is rotatably installed inside the plate base B.

[0016] Preferably, the support block is an inverted T-shaped mechanism, and the vertical end of the support block is located between the two frame plates. The bottom left and right sides of the sleeve block B are attached to the inner wall of the plate base B. The two frame plates can guide and limit the support block to ensure the stability of the support block when it moves. The movement of the support block pushes the iron frame and changes the position of the fine-tuning iron frame.

[0017] An electromagnetic diaphragm assembly method includes the following steps:

[0018] The first step is to transport the processed electromagnetic film from the processing table to the transfer table via the feeding section;

[0019] The second step is to place an iron frame and use an adsorption device to adsorb the electromagnetic film on the surface of the transfer platform, and then transfer it using a five-axis robotic arm.

[0020] The third step is to use a high-definition camera and lighting module to position the electromagnetic film and the iron frame, and then use a five-axis robotic arm to control the adsorption component to adsorb the electromagnetic film and suspend it directly above the iron frame.

[0021] The fourth step is to first press down the second suction cylinder, which drives the electromagnetic diaphragm to bend on the right side and insert it into the right side of the inner wall of the iron frame. Then, by pressing down the first suction cylinder, the electromagnetic diaphragm is driven to bend on the left side and embed itself into the left side of the inner wall of the iron frame.

[0022] Fifth step: The suction of the second auxiliary suction cylinder and the first auxiliary suction cylinder is turned off, so that the two sets of suction nozzles C are separated from the electromagnetic membrane. The vacuum suction of the main suction cylinder is turned into air blowing, so that the electromagnetic membrane is attached to the iron frame with rolled edges, and the assembly is completed.

[0023] The present invention has at least the following beneficial effects:

[0024] 1. The automated mechanism enables rapid feeding, transfer, and assembly of electromagnetic diaphragms, reducing manual intervention, significantly improving production efficiency, and meeting the needs of large-scale production.

[0048] The electromagnetic membrane 32 has a tail insertion end on its side, and the tail insertion end passes through the through groove and inserts into the inner wall of the iron frame 55. The left side of the electromagnetic membrane 32 is engaged and abuts against the left side of the inner wall of the iron frame 55.

[0049] The adsorption component 43 includes a main suction cylinder 431 that is connected to the end of the piston rod of the second telescopic cylinder 42. The bottom of the main suction cylinder 431 is provided with a suction nozzle B433. The left and right sides of the main suction cylinder 431 are respectively provided with a first auxiliary suction cylinder 432 and a second auxiliary suction cylinder 434. The bottom of the shaft ends of the first auxiliary suction cylinder 432 and the second auxiliary suction cylinder 434 are both provided with a sliding plate 435. The suction nozzle C437 is provided below the sliding plate 435.

[0050] The inner side of the slide plate 435 is provided with a guide groove, and the outer sides of the second auxiliary suction cylinder 434 and the first auxiliary suction cylinder 432 are both provided with guide strip ends. The guide strips of the first auxiliary suction cylinder 432 and the second auxiliary suction cylinder 434 are slidably connected to the guide groove of the slide plate 435.

[0051] The outer side of the slide plate 435 is connected to a side frame plate 436. The vertical section of the side frame plate 436 is an inverted L-shaped structure. The horizontal end of the side frame plate 436 is provided with an upper and lower adjustment bolt 438 through a through hole. The shaft end of the upper and lower adjustment bolt 438 is inserted into the top of the second auxiliary suction cylinder 434 or the first auxiliary suction cylinder 432 through a threaded hole.

[0052] The adjustment part 6 includes a bracket 61 fixed to the top of the processing base 1. A plate base B62 is connected to the top of the bracket 61. A threaded screw B64 is rotatably installed inside the plate base B62.

The micro motor B63 is installed on the surface of the bracket 61. A sleeve block B65 is threaded on the surface of the threaded screw B64, and a support block 66 is connected to the top of the sleeve block B65.

[0053] The support block 66 is an inverted T-shaped mechanism, and the vertical end of the support block 66 is located between the two frame plates 53. The bottom left and right sides of the sleeve block B65 are attached to the inner wall of the plate base B62.

[0054] Modular design automates and integrates the assembly process, ensuring close connection between each process, improving overall work efficiency, and reducing manual intervention. The structure of the bearing part 3, including the processing table 33 and the transfer table 31, is used to place and temporarily store the electromagnetic membrane 32. Its function is to provide a stable working platform to ensure that the electromagnetic membrane 32 is fixed in position during processing and transfer, avoiding displacement or damage, and laying the foundation for subsequent assembly steps. The electromagnetic membrane 32 is accurately transferred and positioned by the multi-axis robotic arm 41. Combined with the second telescopic cylinder 42 to control the lifting of the adsorption component, it ensures that the membrane can move flexibly and accurately align with the iron frame 55, improving assembly accuracy.

[0055] The top of the suction nozzle A28 can be connected to a vacuum generator, facilitating the adsorption of the electromagnetic membrane 32 through the suction nozzle A28. The rotation of the threaded screw A23 drives the displacement of the sleeve block A24, controlling the movement of the sleeve block A24 within the groove of the plate base A21. The movement of the sleeve block A24, in conjunction with the first telescopic cylinder 25, can drive the movement. The design of the first telescopic cylinder 25 and the threaded screw A23 can control the horizontal and vertical movement of the electromagnetic membrane 32 adsorbed by the suction nozzle A28, facilitating the transfer of the processed electromagnetic membrane 32 to the surface of the transfer table 31, ensuring the orderly feeding of the electromagnetic membrane 32 onto the surface of the transfer table 31.

[0056] The electromagnetic membrane 32 is designed with a curved structure for installation. The tail end of the electromagnetic membrane 32 on the right side can be inserted into the through slot of the iron frame 55 during installation to position the electromagnetic membrane 32. Finally, the electromagnetic membrane 32 bends on the left side and snaps inward to the left side of the inner wall of the iron frame 55, which ensures the ease of assembly of the electromagnetic membrane 32. With the cooperation of the main suction cylinder 431, the first auxiliary suction cylinder 432 and the second auxiliary suction cylinder 434, there are two additional adsorption structures compared with the traditional structure. The two suction nozzles C437 and B433 can cooperate to adsorb the electromagnetic membrane 32, which facilitates the local adjustment of the electromagnetic membrane 32, meets the bending assembly requirements of the electromagnetic membrane 32, facilitates the mechanical assembly between the electromagnetic membrane 32 and the iron frame 55, and improves the assembly efficiency of the electromagnetic membrane 32 and the iron frame 55.

[0057] When the slide plate 435 moves along the guide strips on the surfaces of the second suction cylinder 434 and the first suction cylinder 432, it ensures the stability of the slide plate 435 during vertical movement, preventing it from wobbling or shifting during the movement of the guide strips on the surfaces of the second suction cylinder 434 and the first suction cylinder 432. This allows the suction nozzle C437 to move stably downwards and adsorb onto both sides of the top of the electromagnetic membrane 32. By independently moving the suction nozzles C437 on the left and right sides downwards, the electromagnetic membrane 32 can be freely bent on both sides, facilitating the assembly of the electromagnetic membrane 32 with the iron frame 55. The installation involves rotating the upper and lower adjusting bolts 438 to press down the side frame plate 436, causing the side frame plate 436 to move the sliding plate 435 down on the surface of the second auxiliary suction cylinder 434. This, in turn, pushes and changes the position of the suction nozzle C437. By pressing down the top edge of the electromagnetic diaphragm 32 through the suction nozzle C437, the curvature of the suction nozzle C437 can be adjusted, and the piston position of the second auxiliary suction cylinder 434 can be changed for data recording. The goal is to ensure that the material can be placed into the iron frame 55 from top to bottom. Subsequently, the extension and retraction state of the second auxiliary suction cylinder 434 can be controlled by reasonably recording the data.

[0058] The micro motor B63 starts and controls the rotation of the threaded screw B64. The rotation of the threaded screw B64 drives the sleeve block B65 to move, which in turn drives the support block 66 to push the iron frame 55, changing the position of the iron frame 55. This allows the iron frame 55 to be positioned by the camera image recognition of the high-definition camera supplementary lighting module 54. The two frame plates 53 guide and limit the support block 66 to ensure the stability of the support block 66 during movement. The movement of the support block 66 pushes the iron frame 55, changing and fine-tuning the position of the iron frame 55. The left and right sides of the bottom of the sleeve block B65 are attached to the inner wall of the plate base B62 to prevent the sleeve block B65 from shaking when it moves with the threaded screw B64.

[0059] An electromagnetic diaphragm assembly method includes the following steps:

[0060] The first step is to transport the processed electromagnetic film 32 from the processing table 33 to the surface of the transfer table 31 via the feeding part 2;

[0061] The second step is to place the iron frame 55 and use the adsorption component 43 to adsorb the electromagnetic film 32 on the surface of the transfer platform 31, and then transfer it using the five-axis robotic arm 41.

[0062] The third step involves using the high-definition camera supplementary lighting module 54 to position the electromagnetic film 32 and the iron frame 55, and using the five-axis robotic arm 41 to control the adsorption component 43 to adsorb the electromagnetic film 32 and suspend it directly above the iron frame 55.

[0063] The fourth step is to press down the second suction cylinder 434 to drive the electromagnetic membrane 32 to bend on the right side and insert it into the right side of the inner wall of the iron frame 55. Then, by pressing down the first suction cylinder 432, the electromagnetic membrane 32 is driven to bend on the left side and embed into the left side of the inner wall of the iron frame 55.

[0064] Fifth step: The suction of the second auxiliary suction cylinder 434 and the first auxiliary suction cylinder 432 is turned off, so that the two sets of suction nozzles C437 are separated from the electromagnetic membrane 32. The vacuum suction of the main suction cylinder 431 is converted into air blowing, so that the electromagnetic membrane 32 is attached to the iron frame 55 with rolled edges, and the assembly is completed.

[0065] Working principle: First, according to Figure 2 and Figure 3 As shown, after the electromagnetic membrane 32 is processed on the processing table 33, the micro motor A22 starts and drives the threaded screw A23 to rotate, causing the sleeve block A24 to move on the surface of the threaded screw A23. During the movement of the sleeve block A24, the first telescopic cylinder 25 drives the robot arm 26 to move, changing the position of the cantilever 27, so that several suction nozzles A28 below the cantilever 27 are suspended above the electromagnetic membrane 32. At this time, the piston of the first telescopic cylinder 25 retracts, which can drive the robot arm 26 to move downward. The suction nozzle A28 is attached to the surface of the electromagnetic membrane 32. Under the action of the external vacuum generator, the suction force is generated to firmly adsorb the electromagnetic membrane 32. The first telescopic cylinder 25 controls the upward moving robot arm 26 to move upward, driving the cantilever 27 to move the suction nozzle A28 to control the suspension of the electromagnetic membrane 32. The movement of the suction nozzle A28 is controlled by the movement of the sleeve block A24. When the suction nozzle A28 moves to the surface of the transfer table 31, the suction force of the suction nozzle A28 is turned off, so that the electromagnetic membrane 32 falls to the surface of the transfer table 31.

[0066] Secondly, according to Figure 3 and Figure 4 As shown, after the iron frame 55 is placed, the five-axis robotic arm 41 moves to the transfer platform 31. After the second telescopic cylinder 42 is activated, the piston extends and pushes the suction component 43, causing the suction nozzle B433 at the bottom of the main suction cylinder 431 to press down and suck up the electromagnetic membrane 32. After moving to the high-definition camera supplementary lighting module 54, the high-definition camera of the high-definition camera supplementary lighting module 54 finds the tail edge of the iron frame 55 and then finds the tail edge of the electromagnetic membrane 32. After the system automatically positions the point, the electromagnetic membrane 32 is then moved by the five-axis robotic arm 41 and the second telescopic cylinder 42. The cylinder 42, in conjunction with the suction component 43, is positioned at the center of the iron frame 55. The five-axis robotic arm 41 moves backward to the distance required to insert into the hole in the iron frame 55. Then, the second suction cylinder 434 presses down, causing the front end of the electromagnetic membrane 32 to bend downward at a certain angle. The specific bending angle depends on the size of the material and can be adjusted using the up-and-down adjusting bolt 438 at the top of the second suction cylinder 434. After the five-axis robotic arm 41 moves down to the appropriate position, it moves forward again to insert into the hole in the iron frame 55. Figure 5 and Figure 7As shown, at this point, the electromagnetic membrane 32 completes the head assembly. Then, the five-axis robotic arm 41 stops in place. The piston of the first suction cylinder 432 controls the other suction nozzle C437 to press down, causing the left tail end of the electromagnetic membrane 32 to bend downwards at a certain angle. The specific bending angle is determined by the size of the material and the bending edge of the iron frame 55. The bending degree can be adjusted by the up-and-down adjusting bolt 438 at the top of the first suction cylinder 432. It is advisable to allow it to be placed into the iron frame 55 from top to bottom. The five-axis robotic arm 41 moves down to a distance from the bottom of the iron frame 55 and upwards. The appropriate height is generally 0.5 mm above the inner surface of the iron frame 55. At this time, the vacuum suction of the first auxiliary suction cylinder 432 and the second auxiliary suction cylinder 434 is turned off simultaneously, so that the suction nozzle C437 is separated from the surface of the electromagnetic membrane 32. The vacuum suction of the main suction cylinder 431 is turned into air blowing, and the electromagnetic membrane 32 is successfully attached to the inside of the iron frame 55 with rolled edges. This assembly method effectively solves the problem of the iron frame 55 with rolled edges at both ends. This type of assembly method can be mass-produced normally, effectively saving the problems of poor assembly and low efficiency.
