Description

Technical Field

[0001] This invention belongs to the field of automation technology, and in particular relates to an automated line carrier circulation structure. Background Technology

[0002] In the field of automation equipment, the use of jigs or carriers to position and transport products, parts, etc., that need to be processed, assembled, or tested is a common technique. When jigs or carriers are used in automation equipment, they need to be reusable; therefore, return or circulation devices are installed in the automation equipment.

[0003] For example, Chinese patent document CN221776861U discloses a carrier ring return mechanism for wire harness processing, including a main frame, a head lifting module, a tail lifting module, an upper pulley group, a lower pulley group, and a carrier group; the main frame includes a main plate, an upper main rail, and a lower main rail; the main plate is arranged along the X-axis direction, and the upper and lower main rails are arranged parallel to each other on the front of the main plate; the head lifting module includes a first lifting component and a first auxiliary rail, the first lifting component is located at the right end of the main plate, and the first auxiliary rail is installed on the upper rear side of the output end of the first lifting component, the first lifting component is used to drive the first auxiliary rail to move up or down; the tail lifting module includes a second lifting component and a second auxiliary rail, the second lifting component is located at the left end of the main plate, and the second auxiliary rail is installed on the upper rear side of the output end of the second lifting component, the second lifting component is used to drive the first auxiliary rail to move up or down; The two auxiliary rails move up or down; the upper pulley assembly includes an upper synchronous belt, which is set on the upper side of the upper main rail and wrapped around the upper outer side of the main body plate, and a first insert rod is connected to the upper synchronous belt; the lower pulley assembly includes a lower synchronous belt, which is set on the lower side of the lower main rail and wrapped around the lower outer side of the main body plate, and a second insert rod is connected to the lower synchronous belt; the carrier assembly is a T-shaped plate structure with a T-shaped cross section, and clamps for holding wire harnesses are provided at both ends of the horizontal plate of the carrier assembly. A front-to-back through limiting cavity is opened in the middle of the top surface of the horizontal plate of the carrier assembly, and the front ends of the first insert rod and the second insert rod can be inserted into the limiting cavity of the carrier assembly respectively; the first auxiliary rail and the second auxiliary rail move up simultaneously and dock with both ends of the upper main rail to form an upper long rail, and the carrier assembly is slidably connected to the upper long rail; the first auxiliary rail and the second auxiliary rail move down simultaneously and dock with both ends of the lower main rail to form a lower long rail, and the carrier assembly is slidably connected to the lower long rail.

[0004] The first and second lifting components simultaneously drive the first and second auxiliary rails upwards, respectively, to connect with both ends of the upper main rail to form the upper long rail. Simultaneously, the upward movement of the first auxiliary rail causes the vehicle assembly to move upwards, limiting the front end of the first insert rod within the limiting cavity. The rotation of the upper synchronous belt drives the first insert rod to move to the left along the X-axis, thereby causing the vehicle assembly to move to the left until it reaches the second auxiliary rail of the upper long rail. Then, the first and second lifting components simultaneously drive the first and second auxiliary rails downwards, respectively, to connect with both ends of the lower main rail to form the lower long rail. Simultaneously, the downward movement of the second auxiliary rail causes the vehicle assembly to move downwards, limiting the front end of the second insert rod within the limiting cavity. Finally, the rotation of the lower synchronous belt drives the second insert rod to move to the right along the X-axis, thereby causing the vehicle assembly to move to the right back to its initial position.

[0005] The technical solution disclosed in the aforementioned patent documents utilizes two upper and lower conveyor belts and lifting components at both ends to achieve fixture circulation. However, to achieve transmission, a rod needs to be installed on the lower synchronous belt. Since the synchronous belt is made of a flexible material, installing a rod would damage the belt's structure, leading to problems such as belt breakage. Furthermore, when the rod rotates to the synchronous pulley position, it causes deformation and tension in the synchronous belt, potentially leading to further belt breakage or damage to the synchronous pulley. Summary of the Invention

[0033] In one embodiment of the automated line carrier circulation structure of the present invention, please refer to... Figures 1 to 10 The automated line carrier circulation structure of this embodiment can be applied to automated production lines to realize the recycling of carriers or fixtures in automated production lines. The automated line carrier circulation structure of this embodiment includes a machine base 100, a return device 200, a tilting device 300, a pushing mechanism 400, and a carrier 500. Specifically: Reference Figure 1 and Figure 2 The machine base 100 is provided with a panel 110, and a stand 120 is provided on the panel 110. A first guide rail 121 is provided on the upper side of one side of the stand 120.

[0034] Reference Figures 1 to 4The return device 200 is located on the bottom side of the panel 110. The return device 200 includes a guide rail frame 210, a mounting frame 220, and a chain drive mechanism 230. The guide rail frame 210 is located on the bottom side of the panel 110 and has a second guide rail 211. The mounting frame 220 is located on the bottom side of the guide rail frame 210. The chain drive mechanism 230 is located on the mounting frame 220. The first end of the chain drive mechanism 230 is connected to a drive mechanism 240, which drives the first end of the chain drive mechanism 230 to swing up and down or rise and fall. Preferably, the mounting frame 220 includes a fixed frame 221 and a movable frame 222. One end of the movable frame 222 is rotatably connected to one end of the fixed frame 221. One end of the chain drive mechanism 230 is located on the movable frame 222, and the other end is located on the fixed frame 221. The drive mechanism 240 is connected to the movable frame 222 and is used to drive the movable frame 222 to swing. Furthermore, the drive mechanism 240 includes a telescopic cylinder 241, the bottom end of which is rotatably connected to a base 242, which is connected to the frame. The upper end of the telescopic cylinder 241 is rotatably connected to a movable frame 222. The telescopic cylinder 241 extends and retracts, driving the movable frame 222 to swing, thus realizing the swing of the first end of the chain drive mechanism 230. Specifically, the chain drive mechanism 230 includes two driven sprockets 231, a chain 232, a drive sprocket 233, and a motor 234. The two driven sprockets 231 are respectively mounted on the movable frame 222 and the fixed frame 221; the chain 232 is wound around the two driven sprockets 231; the drive sprocket 233 is mounted on the fixed frame 221 and meshes with the chain 232; the motor 234 is connected to the drive sprocket 233. The motor 234 drives the drive sprocket 233 to rotate, and the drive sprocket 233 meshes with the chain 232, causing the chain 232 to rotate together. When the drive mechanism 240 drives the movable frame 222 to swing up and down, the driven sprocket 231 on the movable frame 222 drives the chain 232 to swing.

[0035] Furthermore, referring to Figure 3 and Figure 4The movable frame 222 includes a rotating plate 223, a slide block 224, and a buffer spring 225. The rotating plate 223 is rotatably connected to the fixed frame 221, and one end of the rotating plate 223 is provided with a slide groove 226. One end of the slide block 224 is slidably connected to the slide groove 226. The buffer spring 225 is disposed in the slide groove 226, with one end abutting against the slide block 224 and the other end abutting against the inner end face of the slide groove 226. A driven sprocket 231 is disposed at one end of the slide block 224. In this embodiment, the buffer spring 225 provides a certain tension force to the driven sprocket 231, tightening the chain 232. When the drive mechanism 240 pulls the movable frame 222 to swing downwards, the upper chain 232 will tighten, while the lower chain 232 will loosen. Under the action of the buffer spring 225, the buffer spring 225 will be compressed, allowing the rotating plate 223 to swing smoothly. In a further preferred embodiment, the rotating plate 223 is also provided with a clearance groove 227, and a mounting part is formed between the clearance groove 227 and the sliding groove 226. The mounting part is provided with a through hole, and an adjusting screw 228 passes through the through hole and is rotatably connected to the sliding seat 224. The other end of the adjusting screw 228 is provided with an adjusting nut 229. By cooperating with the adjusting screw 228, the position of the driven sprocket 231 is adjusted, thereby adjusting the tension of the chain 232.

[0036] Furthermore, referring to Figure 3 The fixed frame 221 is provided with two support guide wheels 250 at one end near the movable frame 222. The two support guide wheels 250 support the upper and lower chains 231 of the chain drive mechanism 230 respectively. When the movable frame 222 swings downward, the chain 231 can be supported by the support guide wheels 250.

[0037] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 A flipping device 300 is located at one end of the upright frame 120. The flipping device 300 includes a rotating shaft 310, a flip plate 320, and a driving member 330. Support seats 311 are provided at both ends of the rotating shaft 310, and the support seats 311 are supported on the machine base 100. The flip plate 320 is located on the rotating shaft 310, and a third guide rail 340 is provided on one side of the flip plate 320. The driving member 330 is connected to the rotating shaft 310 and is used to drive the rotating shaft 310 to rotate, causing the third guide rail 340 to alternately flip to one end of the first guide rail 121 and one end of the second guide rail 211. The first guide rail 121, the third guide rail 340, and the second guide rail 211 form a transmission line. Further, the driving member 330 is a motor mounted on the upright frame 120. A blocking member 341 is provided at one end of the third guide rail 340.

[0038] Reference Figure 1 and Figure 9The carrier 500 is mounted on the transmission line. A limiting member 510 is provided on the top or bottom side of the carrier 500. The limiting member 510 is used to engage with the chain 231 of the chain drive mechanism 230. Specifically, the limiting member 510 includes a limiting sleeve 511, a compression spring 512, and a pin 513. The limiting sleeve 511 is mounted on the carrier 500, the compression spring 512 is located inside the limiting sleeve 511, and one end of the pin 513 extends into the limiting sleeve 511, while the other end extends out of the limiting sleeve 511, with the extended portion engaging with the chain 231.

[0039] The pushing mechanism 400 is mounted on the frame 120 and is used to push the carrier 500 on the first guide rail 121 to the third guide rail 340.

[0040] The automated line carrier circulation structure of this embodiment allows for the sequential arrangement of multiple different processing, assembly, or testing devices and apparatuses on one side of the first guide rail 121. The specific devices or apparatuses are determined according to the actual application. Multiple carriers 500 are arranged on the first guide rail 121, and products to be processed, assembled, or tested can be positioned on the carriers 500. The pushing mechanism 400 gradually pushes the carriers 500 to each workstation to complete the processing, assembly, or testing, and then the products or parts on the carriers 500 are removed. Finally, the pushing mechanism 400 pushes the carrier 500 onto the third guide rail 340 of the flipping device 300. The driving component 330 of the flipping device 300 drives the flip plate 320 to rotate 180°, so that the third guide rail 340 aligns with the second guide rail 211. At the same time, the limiting component 510 on the carrier 500 is positioned above the chain 231. The driving mechanism 240 drives the movable frame 222 to move upward, allowing the pin 513 of the limiting component 510 to be inserted into the tooth groove of the chain 232 and engage with the tooth groove. Therefore, under the transmission of the chain drive mechanism 230, the carrier can be returned to its starting position, thus enabling the carrier 500 to be used cyclically. Because the return of the carrier 500 is achieved by the engagement of the limiting component 510 of the carrier 500 with the chain 232 of the chain drive mechanism 230, the structure is simpler, and problems such as chain breakage are avoided, ensuring normal return.

[0041] Furthermore, refer to Figure 7The pushing mechanism 400 includes a translation component 410, a slide rod 420, and a rotation drive component 430. The translation component 410 is located on one side of the stand 120. The translation component 410 includes an electric lead screw module 411 and a movable seat 412 connected to the electric lead screw module 411. A slide rail 122 is also provided on the top side of the stand 120, and the slider of the slide rail 122 is fixedly connected to the stand 120. The slide rod 420 is fitted with multiple connecting seats 422, and the connecting seats 422 are connected to the slide rail 122. A connecting member 440 is provided between the slide rod 420 and the movable seat 412. The rotation drive component 430 is connected to the slide rod 420 and is used to drive the slide rod 420 to rotate. The slide rod 420 is provided with multiple levers 421. The carrier 500 is provided with a lever groove 501 that cooperates with the levers 421. In this embodiment, the rotating drive unit 430 can push the slide bar 420 to rotate at a certain angle, causing the lever 421 to rotate into the actuation groove 501. The electric lead screw module 411 drives the moving seat 412 to translate, and under the action of the connecting member 440, it drives the slide bar 420 to move together with the moving seat 412. This, in turn, pushes the carrier 500 to translate along the first guide rail 121.

[0042] Furthermore, refer to Figure 7 The rotating drive component 430 includes a cylinder 431, a mounting portion 413 extending from the movable seat 412, and a connecting portion 423 extending from the slide rod 420. One end of the cylinder 431 is rotatably connected to the mounting portion 412, and the other end is rotatably connected to the connecting portion 423. A connecting member 440 connects the slide rail 122 and the movable seat 412. In this embodiment, the cylinder 431 pushes the slide rod 420 to rotate, causing the lever 421 to engage or disengage from the actuation groove 501. When the movable seat 412 translates, the connecting member 440 drives the slide rail 122 to move together, thereby driving the slide rod 420 to move.

[0043] Furthermore, refer to Figure 5 and Figure 6 The flip plate 320 is also provided with a positioning seat 321 on one side, and the positioning seat 321 is provided with a positioning hole 322; the upper and lower ends of the upright frame 120 are provided with positioning cylinders 130, and the telescopic end of the positioning cylinder 130 is also provided with a positioning pin 131. After the flip plate 320 flips over, the positioning cylinder 130 pushes the positioning pin 131 to insert into the positioning hole 322 of the positioning seat 321, thereby limiting the flip plate 320.

[0044] Furthermore, the automated line carrier circulation structure of this embodiment also includes a carrier positioning mechanism 600 for positioning the carrier 500 on the first guide rail 121. Please refer to [link / reference needed] for details. Figure 1 , Figure 8 and Figure 9The carrier positioning mechanism 600 includes a swing arm 610 and a swing drive component 620. The swing arm 610 has adapter seats 630 at both ends, which are fixedly connected to the upright frame 120. Multiple positioning rods 611 are provided on the swing arm 610. The swing drive component 620 is mounted on the upright frame 120 and connected to the swing arm 610, used to drive the swing arm 610 to swing. The bottom side of the carrier 500 also has a positioning groove 502. When processing, assembling, or testing products or parts on the carrier 500, the carrier positioning mechanism 600 positions the carrier 500. Specifically, the swing drive component 620 drives the swing arm 610 to rotate a certain angle, causing the positioning rods 611 to be positioned within the positioning groove 502.

[0045] Furthermore, a third guide rail 340 is provided on both sides of the flap 320. This allows the flap 320 to receive the pushed-in carrier 500 on both sides, with one carrier 500 located at one end of the first guide rail 121 and the other carrier 500 located at one end of the second guide rail 211, thereby improving the return efficiency of the carrier 500.

[0046] Furthermore, the flipping device 300 consists of two sets, located at both ends of the return device 200. This enables fully automated circulation of the vehicle 500.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
