Description

Technical Field

[0001] This invention belongs to the field of inspection port assembly technology, specifically relating to an automatic assembly device used on an automatic assembly line for the inner and outer frames of an aluminum inspection port. Background Technology

[0002] Access panels (also known as access doors or air vents) are widely used in ceilings and walls due to their lightweight, aesthetic appeal, durability, and ease of molding, to conceal and facilitate the maintenance of pipelines and equipment. Access panels typically consist of components such as an inner frame, an outer frame, and a cover plate. The quality of their assembly directly affects the flatness, airtightness, and reliability of the installed panel.

[0003] Traditional access panel assembly relies primarily on manual operation or semi-automatic equipment. In manual assembly, workers must manually handle inner and outer frame parts, performing a series of operations such as alignment, clamping, and fastening (e.g., screws). This method has significant drawbacks: First, it is inefficient and labor-intensive, making it difficult to meet the demands of large-scale mass production. Second, assembly quality is highly dependent on worker skill and focus, easily leading to problems such as inaccurate positioning, uneven clamping force, missing screws, or improper torque, resulting in poor product consistency and the potential for loosening or deformation. Furthermore, frequent manual handling and repetitive operations increase labor costs and management complexity. Summary of the Invention

[0037] To make the objectives, technical solutions, and advantages 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 and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0038] Example 1: refer to Figures 2-10 An automatic assembly device for use on an automatic assembly line for inner and outer frames of an aluminum inspection port includes a workbench 10 and an assembly platform 20. The assembly platform 20 is installed on the surface of the workbench 10 and provides a displacement assembly part and a clamping part. The clamping part clamps the inspection port 50 and the displacement assembly part automatically assembles the inspection port 50. In this embodiment of the invention, the clamping part can securely clamp the inspection port 50, and the displacement assembly part can automatically complete the assembly of the inspection port 50. This automates the assembly process of the inspection port 50 and effectively improves assembly efficiency.

[0039] refer to Figure 1 and Figure 11 The feeding device 40 is located around the workbench 10 and is used to transport the parts required for assembling and fixing the inspection port 50. In this embodiment of the invention, the feeding device 40 is used to automatically transport the parts used for assembling the inspection port 50, so that the entire assembly process is freed from the dependence on manual handling of parts. This not only effectively improves the efficiency and accuracy of parts transportation and ensures that parts can arrive at the designated assembly position in a timely and accurate manner, but also further optimizes the continuity and smoothness of the assembly process, laying a solid foundation for the efficient and high-quality assembly of the inspection port 50.

[0040] refer to Figures 11-17 The transport device 30 is installed on the assembly platform 20. The transport device 30 includes a first transport group 325, a second transport group 326 and a third transport group 327. The first transport group 325, the second transport group 326 and the third transport group 327 are used to clamp the parts in the feeding device 40 and assemble the clamped parts with the inspection port.

[0041] In this embodiment of the invention, the first transport group 325 and the second transport group 326 have identical structures, both intended to hold parts within the feeding device 40. The transport device 30 is precisely mounted on the assembly platform 20, undertaking the crucial task of picking up parts from the feeding device 40. Through precise mechanical movements and control, it can stably and efficiently remove parts from the feeding device 40 and accurately assemble them with the inspection port 50. This achieves seamless integration of parts from storage to assembly, greatly improving the automation and coordination of the entire inspection port 50 assembly process, effectively reducing manual intervention, and minimizing assembly errors caused by human factors, thereby ensuring the quality and efficiency of the inspection port assembly.

[0042] The assembly platform 20 includes a circular assembly disk 201 with guide grooves 202 distributed on its surface; the displacement assembly section is provided with four sets of circumferential arrays distributed below the assembly disk 201, and the clamping part is provided in each displacement assembly section.

[0043] In the embodiments of the present invention, reference is made to Figures 2-4In this product, four inspection ports 50 are used to assemble an inner and outer frame of an inspection port. Four sets of displacement assembly parts are set, each corresponding to one of the four inspection ports 50. The automated assembly function is achieved by operating each displacement assembly part. First, the clamping part is clamped, and then the displacement assembly part is automatically assembled. It should be noted that the four inspection ports 50 need to be placed on the surface of the assembly tray 201, corresponding to the positions of the four displacement assembly parts. The placement of the inspection ports 50 also needs to be achieved by a mechanical automation mechanism, such as a robotic arm or an electric pusher, to push the four inspection ports 50 one by one into the surface of the assembly tray 201, corresponding to each displacement assembly part. This invention does not disclose the material release structure of the inspection ports 50, so the material release structure of the inspection ports 50 is not protected here. Alternatively, even if the automatic placement function of the inspection ports 50 is not used, manual material release can be used. This product can still achieve the function of automatic assembly without affecting the overall function of the equipment.

[0044] refer to Figures 1-10 The displacement assembly includes a base plate 203, with side plates 204 fixed on both sides of the base plate 203. The side plates 204 are fixed below the assembly plate 201. A clamping motor 217 is fixedly installed at the bottom of the base plate 203. A driven gear 218 meshes with the output end of the clamping motor 217. A screw 219 is fixedly connected to the driven gear 218. A transmission block 220 is driven and engaged on the screw 219. A slide plate 207 is fixedly connected to the transmission block 220. A first slider 206 is fixedly installed at the bottom of the slide plate 207. A first track 205 is fixedly connected to the surface of the base plate 203. The first slider 206 is slidably mounted on the first track 205. A second track 208 is fixedly connected to the surface of the slide plate 207. The clamping part is slidably mounted on the second track 208.

[0045] In this embodiment of the invention, since the output end of the clamping motor 217 is engaged with the driven gear 218, it can be known (in conjunction with the appendix) that Figure 7 The output end of the clamping motor 217 is also a gear structure. When the driven gear 218 rotates, its screw 219 will rotate synchronously. Since the bottom of the slide plate 207 is slidably engaged with the first track 205 through the first slider 206, the rotation of the screw 219 causes the position of the transmission block 220 to change. That is, the transmission block 220 drives the slide plate 207 to slide and displace on the first track 205. Since the clamping part is slidably assembled on the second track 208, when the slide plate 207 moves, it will synchronously drive the clamping part to move, thereby automatically assembling and splicing the parts clamped by the clamping part.

[0046] In this embodiment of the invention, optionally, the clamping motor 217 is a stepper motor, which has functions such as precise position control, good low-speed torque, and good synchronization. It is suitable for scenarios with medium and low speed, high precision requirements, cost sensitivity, and feasible open-loop control. The screw 219 and the transmission block 220 are fitted with a ball screw. The ball screw has high transmission efficiency, requires less torque from the motor, consumes less energy, and generates less heat. A smaller power servo or stepper motor can be selected, saving overall system cost and energy consumption.

[0047] refer to Figures 5-10 The clamping part includes a support plate 210. A second slider 209 is fixed to the bottom of the support plate 210 and slidably assembled with the second track 208. A pusher 212 is also fixed to the surface of the slide plate 207. The output end of the pusher 212 has a push rod 213. A linkage plate 211 is fixed on the push rod 213 and is fixed below the support plate 210. A fixing block 214 is also fixed to the surface of the slide plate 207. The fixing block 214 extends out of the support plate 210. An extension rod 215 is fixedly connected to the top of the fixing block 214. A pad 216 is fixed to the surface of the support plate 210. The pad 216 and the fixing block 214 extend into a guide groove 202 located on the surface of the assembly plate 201.

[0048] In this embodiment of the invention, the pusher 212 is preferably a pneumatic structure. Pneumatic structures react quickly and can respond rapidly during operation via the push rod 213. The push rod 213 pushes the linkage plate 211 to move, meaning the linkage plate 211 causes the support plate 210 to slide on the second track 208. Here, the fixing block 214 and the extension rod 215 are fixed to the surface of the slide plate 207, while the pad 216 is fixed to the surface of the support plate 210. Therefore, when the support plate 210 moves, it will cause the pad 216 to move closer to the extension rod 215, completing a clamping action. The inspection port 50 is clamped between the pad 216 and the extension rod 215. Subsequently, through the linkage of the displacement assembly parts, the inspection port 50 is assembled. (Reference) Figure 7 In the direction of the arrow, the access port 50 needs to be inserted from the side between the pad 216 and the extension rod 215 (automatic mechanical insertion or manual insertion), and then clamped by the start-up pusher 212; here, since the guide groove 202 of the pad 216 and the fixing block 214 extends from the surface of the assembly plate 201, it means that the access port 50 is clamped by the pad 216 and the extension rod 215 on the surface of the assembly plate 201 (see reference). Figure 10 and Figure 17 ).

[0049] refer to Figure 3 A reversing motor 221 is fixedly connected inside the workbench 10, and a large gear 222 is fixedly connected to the bottom of the assembly plate 201. The large gear 222 meshes with the output end of the reversing motor 221.

[0050] In this embodiment of the invention, the assembly disk 201 is rotatably mounted on the assembly platform 20. When the reversing motor 221 starts, the gear at the output end of the reversing motor 221 meshes with the large gear disk 222, thereby causing the assembly disk 201 to rotate. The rotation of the assembly disk 201 means that the positions of the displacement assembly part and the clamping part will change. Here, since the inspection port 50 needs to be inserted from the side between the pad 216 and the extension rod 215 (see...) Figure 7 (Arrow direction) Here, four access ports 50 need to be inserted. Using the reversing motor 221: ① In manual insertion, workers only need to stand in one direction, insert one access port 50, and then start the reversing motor 221 to rotate the assembly plate 201 by 90°. This allows workers to insert all four access ports 50 from one location without adjusting their position; ② Similarly, when using a robotic arm, only one automatic insertion mechanism needs to be set up in one direction. Each time the automatic insertion mechanism performs one... The insertion action is that the reversing motor 221 starts once until all four inspection ports 50 are inserted into each clamping part; ③: Supplement to the usage scheme in ②. Method ② uses an automatic insertion mechanism. Here, two automatic insertion mechanisms are set (symmetrically set). This way, two inspection ports 50 can be inserted at the same time on both sides. When two automatic insertion mechanisms are set, the output angle of the reversing motor 221 is 180°, which means that only two insertions are needed to insert all four inspection ports 50 into the assembly plate 201 and clamp them with the pad block 216 and the extension rod 215.

[0051] Example 2: The first material handling component 309, the second material handling component 310, the third material handling component 321, the fourth material handling component 323, and the fifth material handling component 324 of the present invention have the same structure and function. In the following embodiments, only the structure of the first material handling component 309 is disclosed and described. The functions of the other material handling components are the same as the structure of the first material handling component 309. The common structure of each material handling component is the lifting motor 307 and the clamping cylinder 308.

[0052] refer to Figures 11-14 The transport device also includes a top plate 301, which is installed above the assembly plate 201. A third track 315 is fixed on the surface of the top plate 301. The first transport group 325, the second transport group 326 and the third transport group 327 are all slidably assembled on the third track 315. The third transport group 327 is located between the first transport group 325 and the second transport group 326.

[0053] In this embodiment of the invention, the structures of the first transport group 325 and the second transport group 326 are mirror images, and their functions are identical. The bottom of the top plate 301 has a support leg 302, which supports the surface of the worktable 10.

[0054] The first transport group 325 includes a shared arm 303. A third slider 316 is fixed at the bottom of the shared arm 303 and slidably assembled with a third track 315. A first drive motor 304 and a second drive motor 305 are fixed on both sides of the shared arm 303 respectively. A first material picking component 309 and a second material picking component 310 are slidably assembled on the shared arm 303. In this embodiment of the invention, since the first transport group 325 and the second transport group 326 have the same function, it means that the overall structure and function are the same. Here, the first transport group 325 is described as an example. In the shared arm 303 of the first transport group 325, the first picking component 309 and the second picking component 310 are slidably assembled at both ends of the shared arm 303, which means that the two first picking components 309 and the second picking component 310 can be used to clamp parts in the two feeding devices; The first material handling assembly 309 includes a displacement plate 306, which is slidably mounted on the shared arm 303. A lifting motor 307 is installed on one side of the displacement plate 306. A clamping cylinder 308 is fixedly connected to the output end of the lifting motor 307. The clamping cylinder 308 is used to clamp the parts in the feeding device 40. The second transport group 326 is provided with a fourth material handling assembly 323 and a fifth material handling assembly 324.

[0055] In this embodiment of the invention, the displacement plate 306 is slidably mounted on the shared arm 303, and a first transmission motor 304 and a second transmission motor 305 are respectively fixed on both sides of the shared arm 303. The first transmission motor 304 and the second transmission motor 305 can drive the displacement plate 306 to move on the shared arm 303 when they are activated. That is, the first transmission motor 304 drives the first material picking component 309, and the second transmission motor 305 drives the second material picking component 310. Specifically, the displacement plate 306 has a threaded sleeve structure on its side, and the power output of the first transmission motor 304 is given to the threaded rod. Thus, the displacement plate 306 achieves transmission through a threaded transmission engagement. The same transmission structure as the screw 219 and the transmission block 220 can be referred to here. The specific transmission method of the displacement plate 306 is not limited and can be any translational transmission method, such as a linear motor. When picking up a part from the feeding device 40, the first drive motor 304 first drives the first picking component 309 to move above the feeding device 40 (directly above the part). Then, the lifting motor 307 is started to control the clamping cylinder 308 to descend. The clamping cylinder 308 moves onto the part to perform the clamping operation. After the clamping cylinder 308 clamps the part, the lifting motor 307 is started again to control the clamping cylinder 308 to rise to complete the picking operation. It should be noted that for the convenience of position description, the x, y, z coordinate system in the figure is used to describe the directional relationship. Here, the first drive motor 304 and the second drive motor 305 change the x-direction coordinate position of the first picking component 309 and the second picking component 310, and the first picking component 309 and the second picking component 310 change the z-direction coordinate position of the clamping cylinder 308.

[0056] The first material handling component 309 and the second material handling component 310 can simultaneously pick up parts. Similarly, the fourth material handling component 323 and the fifth material handling component 324 can simultaneously pick up parts. The third material handling component 321 also picks up materials simultaneously. The setting of multiple material handling components can greatly improve the material handling speed and further improve production efficiency.

[0057] A first assembly motor 311 is fixed on one side of the shared arm 303. The output end of the first assembly motor 311 is connected to a drive gear 312. A bidirectional rack 314 is also fixed on the surface of the top plate 301 and meshes with the drive gear 312. The first assembly motor 311 is installed on the first transport group 325, and a second assembly motor 313 is installed on the second transport group 326. The drive gears 312 of the first assembly motor 311 and the second assembly motor 313 are located on both sides of the bidirectional rack 314, respectively.

[0058] In the embodiments of the present invention, both the first assembly motor 311 and the second assembly motor 313 are provided with a drive gear 312. Since the drive gear 312 meshes with the bidirectional rack 314, it means that the first assembly motor 311 can change the position of the first transport group 325 in the y-direction coordinate, and similarly the second assembly motor 313 can also change the position of the second transport group 326 in the y-direction coordinate. In summary, the system integrates adjustable coordinates in the x, y, and z directions, namely, left-right (x), front-back (y), and up-down (z) directions. This allows for convenient installation of parts held by the first material handling assembly 309, the second material handling assembly 310, the third material handling assembly 321, the fourth material handling assembly 323, and the fifth material handling assembly 324 onto each inspection port 50.

[0059] The third transport group 327 includes an adjustable pitch motor 317, which is fixed on the top plate 301. A first wide rail plate 318 is connected to one side of the adjustable pitch motor 317. A push motor 319 is slidably mounted on the first wide rail plate 318. A second wide rail plate 320 is connected to one side of the push motor 319. A third material handling component 321 is slidably mounted on the second wide rail plate 320. A fourth slider 322 is fixed to the bottom of the push motor 319 and slidably mounted on the third rail 315.

[0060] In this implementation plan, reference is made to Figure 14 The adjustable-pitch motor 317 drives the push motor 319 to move on the first wide rail plate 318, and the push motor 319 drives the third material handling component 321 to move on the second wide rail plate 320. Both are controlled by a screw drive. Specific structural details are not shown here, but the interaction between the screw 219 and the transmission block 220, or other drive methods such as linear motors, can be referenced. The output structure principle is not limited here. The adjustable-pitch motor 317 can change the y-axis position of the push motor 319, and the push motor 319 can change the x-axis position of the third material handling component 321. The third material handling component 321 adjusts its z-axis position.

[0061] Example 3: For details of this implementation, please refer to the reference. Figure 11 and Figures 15-17 ,exist Figure 11The corresponding values ​​(321,e), (310,b), (323,a), (324,c), and (309,d) are given. Here, a, b, c, and d are all clamping cylinders 308. (323,a) represents that cylinder a is located on the fourth material handling component 323; (310,b) represents that cylinder b is located on the second material handling component 310; (324,c) represents that cylinder c is located on the fifth material handling component 324; (309,d) represents that cylinder d is located on the first material handling component 309; and (321,e) represents that cylinder e is located on the third material handling component 321.

[0062] The feeding device 40 includes a first vibrating feeder 401, a second vibrating feeder 402, a third vibrating feeder 403, a fourth vibrating feeder 404, and a fifth vibrating feeder 405.

[0063] In this implementation scheme, corresponding to (321,e), (310,b), (323,a), (324,c), and (309,d) above, it can be deduced similarly that the third material handling component 321 is used to clamp the sheet metal sheet 601 in the fifth vibrating feeder 405, the fifth material handling component 324 clamps the corner sheet metal 60 in the second vibrating feeder 402, the first material handling component 309 clamps the corner sheet metal 60 in the first vibrating feeder 401, the second material handling component 310 clamps the corner sheet metal 60 in the fourth vibrating feeder 404, and the fourth material handling component 323 clamps the corner sheet metal 60 in the third vibrating feeder 403.

[0064] The inner and outer frames of the inspection port are formed by splicing four inspection ports. The two sides of the inspection port are set with a 45° bevel angle. The parts inside the feeding device 40 are corner sheet metal 60 and sheet metal sheet 601. The first vibrating feeder 401, the second vibrating feeder 402, the third vibrating feeder 403 and the fourth vibrating feeder 404 are all corner sheet metal 60, and the fifth vibrating feeder 405 is sheet metal sheet 601. In this embodiment of the invention, the 45° bevel angle is used to assemble a rectangular inner and outer frame of the inspection port through the four inspection ports. The corner sheet metal 60 is assembled on the four corners of the rectangular inner and outer frame of the inspection port, and the sheet metal piece 601 is only assembled on one of the inspection ports 50. The inspection port has an L-shaped structure, and its inspection port is clamped between the pad block 216 and the extension rod 215. The structure of the pad block 216 and the extension rod 215 is designed to match the shape of the inspection port. The pad block 216 can support the inspection port 50, and the function of stable clamping is achieved by the pad block 216 moving closer to the extension rod 215.

[0065] Among them, reference Figure 15When installing the four corner sheet metal pieces 60 onto each inspection port 50, the sheet metal piece 601 on the e-cylinder must first be inserted into one of the inspection ports 50. The specific steps are as follows: the pitch motor 317 drives the push motor 319 to move on the first wide rail plate 318, and the fourth slider 322 slides synchronously on the third rail 315, positioning the push motor 319 above the sheet metal piece 601. Then, the push motor 319 is activated to drive the third material handling assembly 321 to move on the second wide rail plate 320, causing the third material handling assembly... The displacement 321 is directly above the sheet metal sheet 601. The sheet metal sheet 601 is clamped by the e-cylinder. Then, the pitch adjustment motor 317, the push motor 319, and the lifting motor 307 in the third material handling assembly 321 are adjusted again to change the position of the x, y, and z axes so that the sheet metal sheet 601 clamped by the e-cylinder is just located on the side of the inspection port 50. Finally, the y-axis direction is changed by the pitch adjustment motor 317, and the sheet metal sheet 601 is slid into the inspection port 50. The e-cylinder releases the clamping action, and the above steps are repeated to continue the next set of clamping operations.

[0066] After the sheet metal piece 601 is inserted, the next step is to assemble the four corner sheet metal pieces 60. The specific steps are as follows: the first material handling component 309, the second material handling component 310, the fourth material handling component 323, and the fifth material handling component 324 can work simultaneously, using a, b, c, and d respectively to clamp the corresponding corner sheet metal pieces 60 on the vibrating feeder. Specifically, the fifth material handling component 324 clamps the corner sheet metal piece 60 in the second vibrating feeder 402, the first material handling component 309 clamps the corner sheet metal piece 60 in the first vibrating feeder 401, the second material handling component 310 clamps the corner sheet metal piece 60 in the fourth vibrating feeder 404, and the fourth material handling component 323 clamps the corner sheet metal piece 60 in the third vibrating feeder 403. The specific steps for picking up materials are the same for the first picking component 309, the second picking component 310, the fourth picking component 323, and the fifth picking component 324. Taking the first picking component 309 as a detailed example: The first drive motor 304 first drives the first picking component 309 to move so that the cylinder d is directly above the first vibrating feeder 401. Then, the lifting motor 307 is started to control the clamping cylinder 308 to descend, and the clamping cylinder 308 moves onto the part to perform the clamping work. After the clamping cylinder 308 clamps the part, the lifting motor 307 is started again to control the clamping cylinder 308 to rise to complete the picking operation. Subsequently, the first drive motor 304 is started again to control the clamping cylinder 308 to rise to complete the picking operation. Motor 304 changes the position of the first material handling component 309 in the x-axis direction, and together with the first material handling component 309, changes the position of the clamping cylinder 308 in the z-axis direction. Then, the first assembly motor 311 starts, changing the position of the first transport group 325 in the y-axis direction. By adjusting the positions in the x, y, and z axes, the corner sheet metal 60 clamped by the d cylinder is positioned exactly on the side of the inspection port 50. Finally, the first assembly motor 311 changes the position of the first transport group 325 in the y-axis direction, and the corner sheet metal 60 is slidably inserted into the inspection port 50. The d cylinder then releases its clamping action, and the above steps are repeated to continue the next set of clamping operations.

[0067] It should be noted that since the first material handling component 309 and the second material handling component 310 are set on the first transport group 325, the first material handling component 309 and the second material handling component 310 cannot simultaneously slide the corner sheet metal 60 into the inspection port 50. This step needs to be operated separately and independently. Similarly, the fourth material handling component 323 and the fifth material handling component 324 also need to be operated separately and independently.

[0068] During assembly: Reference Figure 16 The solid, curved arrow represents the first step, where the sheet metal piece 601 is first inserted into one of the inspection ports 50. Next, the dashed arrow represents the second step, where all four corner sheet metal pieces 60 are inserted into the ends of two inspection ports 50. The other two inspection ports 50 are positioned on the sides of the corner sheet metal pieces 60. Finally, the solid, straight arrow represents the third step, where the inspection ports 50, held by the pad 216 and the extension rod 215, are activated by the clamping motor 217, causing the inspection ports 50 at both ends to shift inwards. This means the other side of the two corner sheet metal pieces 60 will be inserted into the other two inspection ports 50, thus completing the product assembly (the assembled product can be referenced). Figure 2 and Figure 4Because the displacement assembly section has four sets of circular arrays, each displacement assembly section can be controlled independently, realizing the function of the assembly inspection port 50. The initial and starting positions can be adjusted by programming according to actual usage needs. This product is designed for the coordinated control of multiple motors and requires programming and PLC coordinated control to achieve automation. Detailed protection is not provided for this programming and PLC coordinated control.

[0069] The specific implementation process of this invention is as follows: 50mm clamping port for inspection: The inspection port 50 is pushed into the surface of the assembly plate 201, located between the pad 216 and the extension rod 215. The push rod 213 pushes the linkage plate 211 to move, that is, the linkage plate 211 drives the support plate 210 to slide on the second track 208, which drives the pad 216 to approach the extension rod 215, thus completing the clamping action.

[0070] During assembly: Reference Figure 16 The solid curved arrow represents the first step, where the sheet metal piece 601 is first inserted into one of the inspection ports 50. The dashed arrow represents the second step, where all four corner sheet metal pieces 60 are inserted into the two ends of two inspection ports 50. The positions of the other two inspection ports 50 correspond to the sides of the corner sheet metal pieces 60. Finally, the solid straight arrow represents the third step, where the inspection ports 50 held by the pad 216 and the extension rod 215 are started according to the direction of the solid straight arrow. The clamping motor 217 is started, and the inspection ports 50 at both ends are moved inward. That is, the other side of the two corner sheet metal pieces 60 will be inserted into the other two inspection ports 50, thus completing the assembly of the product.
