Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and more specifically, to an assembly machine for automotive armrest box parts. Background Technology

[0002] The car armrest box is an interior accessory installed between two seats. It has two main functions: first, it provides arm support for the driver during long drives, effectively relieving fatigue such as soreness, numbness, and stiffness in the arms, thereby reducing the risk of accidents; second, it provides storage space for small items such as drinks, water cups, and mobile phones, making them convenient for the driver to access.

[0003] Currently, during the assembly of car armrest boxes, different components are usually connected using accessories such as bushings and metal clips to ensure the connection effect and strength between the components. These accessories are generally fixed by an assembly machine and then manually assembled onto the car armrest box components, enabling stable assembly. However, most existing car armrest box accessory assembly machines can only fix the car armrest box components; manual operation is still required for accessory assembly. Since there are many accessories on a car armrest box, manual assembly is not only inefficient, but also difficult for workers to control the installation accuracy due to the small size of the accessories.

[0031] Example:

[0032] Please see Figure 1-8A car armrest box parts assembly machine includes two side bases 1, a central base 2, and a housing 22. The central base 2 is fixedly connected between the two side bases 1, and the housing 22 is fixedly connected to the top of the two side bases 1 and the central base 2. Each side base 1 is fixedly connected to a vibrating feeder module 3 and two robotic arms 4, with each robotic arm 4 corresponding to one of the two vibrating feeder modules 3. The output ends of each of the four robotic arms 4 are fixedly connected to a rotating material picker 5. Magnetic suction rod assemblies 6 are fixedly connected to the circumferential surfaces of each of the four rotating material picker 5, with each of the four magnetic suction rod assemblies 6 corresponding to one of the two vibrating feeder modules 3. Each of the four robotic arms 4 is fixedly connected to a vision industrial camera 7, with each of the four vision industrial cameras 7 corresponding to one of the four magnetic suction rod assemblies 6. A slide table 8 is slidably connected to the central base 2, and a positioning fixture 9 is detachably connected to the slide table 8. Two clamping assemblies 10 are slidably connected to the positioning fixture 9, and the positioning fixture 9 is fixedly connected to... Two telescopic cylinders 11 are connected, and the output ends of the two telescopic cylinders 11 are fixedly connected to two clamping components 10 in opposite directions. Lifting cylinders 12 are fixedly connected to each of the two clamping components 10. Positioning frames 13 are slidably connected to each of the two clamping components 10, and the output ends of the two lifting cylinders 12 are fixedly connected to the two positioning frames 13 respectively. A first vision inspection camera module 19 is fixedly connected to the central base 2. A second vision inspection camera module 20 is fixedly connected to the top wall of the chassis 22. A third vision inspection camera module 21 is fixedly connected to the two side bases 1. The first vision inspection camera module 19, the second vision inspection camera module 20 and the third vision inspection camera module 21 are all corresponding to the positioning fixture 9. A drive mechanism is provided between the slide table 8 and the central base 2. The drive mechanism is used to control the slide table 8 to slide on the central base 2. A quick-release mechanism is provided between the slide table 8 and the positioning fixture 9. The quick-release mechanism is used to quickly replace the positioning fixture 9.

[0033] In this embodiment, the positioning fixture 9 is mounted on the slide table 8 via a quick-release mechanism. When assembling the car armrest box component, the car armrest box component is placed on the positioning fixture 9 through the material discharge port at the front end of the machine housing 22. Two telescopic cylinders 11 control two clamping assemblies 10 to slide close together on the positioning fixture 9 to clamp the car armrest box component. Simultaneously, the two clamping assemblies 10 drive two lifting cylinders 12 and two positioning frames 13 to move. After the two clamping assemblies 10 clamp the car armrest box component from both sides, the two positioning frames 13 are positioned above the car armrest box component. The two lifting cylinders 12 control the two positioning frames 13 to move downwards to press down on the car armrest box component, thus fixing the car armrest box component on the positioning fixture 9. The moving feeder module 3 feeds the parts, and the drive mechanism makes the slide table 8 slide on the central base 2. The slide table 8 drives the positioning fixture 9 to move between the four robotic arms 4. The four robotic arms 4 drive the four rotating pick-up hands 5 to move and rotate, so that the four magnetic suction rod assemblies 6 magnetically grab the parts from the two vibrating feeder modules 3 and assemble them onto the car armrest box component. During the assembly process of the four magnetic suction rod assemblies 6, four vision industrial cameras 7 inspect the parts on the four magnetic suction rod assemblies 6. The first vision inspection camera module 19, the second vision inspection camera module 20 and the third vision inspection camera module 21 inspect the assembly positioning of the parts on the car armrest box component from the front, back, left, right and top, respectively.

[0034] Specifically, the drive mechanism includes a geared motor 241, a gear 242, and a rack 243. The geared motor 241 is fixedly connected to the bottom of the slide table 8, the gear 242 is fixedly connected to the output end of the geared motor 241, and the rack 243 is fixedly connected to the central base 2, and the gear 242 meshes with the rack 243.

[0035] In this embodiment, the gear motor 241 controls the gear 242 to rotate. Through the meshing of the gear 242 and the rack 243, the slide table 8 is driven to slide on the central base 2, thereby realizing the movement of the car armrest box component.

[0036] Specifically, the quick-release mechanism includes two guide roller assemblies 141, a double-hole positioning groove 142, a positioning post assembly 143, a fixing sleeve assembly 144, a double-hole positioning port 145, a positioning cylinder module 146, a limit post assembly 147, two side positioning cylinders 148, and two side pressure plates 149. Both guide roller assemblies 141 are rotatably connected to the slide table 8, and the positioning fixture 9 is located between the two guide roller assemblies 141. The double-hole positioning groove 142 is formed on one side of the positioning fixture 9. The positioning post assembly 143 is fixedly connected to the slide table 8, and the double-hole positioning groove 142 matches the positioning post assembly 143 for fixation. The sleeve assembly 144 is fixedly connected to the bottom end of the slide table 8. The double-hole positioning port 145 is opened on the positioning fixture 9. The positioning cylinder module 146 is fixedly connected to the bottom end of the fixed sleeve assembly 144. The limiting post assembly 147 is fixedly connected to the output end of the positioning cylinder module 146. The limiting post assembly 147 passes through the fixed sleeve assembly 144 and the slide table 8 from bottom to top and is inserted into the double-hole positioning port 145. The two side positioning cylinders 148 are fixedly connected to the slide table 8. The two side pressure plates 149 are fixedly connected to the output ends of the two side positioning cylinders 148 respectively. The two side pressure plates 149 correspond to the positioning fixture 9.

[0037] In this embodiment, when the positioning fixture 9 is assembled and disassembled on the slide table 8, it slides between two guide roller groups 141. The two guide roller groups 141 make the assembly and disassembly of the positioning fixture 9 smoother. During the sliding installation of the positioning fixture 9 on the slide table 8, it is positioned correspondingly to the positioning post assembly 143 through the double-hole positioning groove 142. After the positioning fixture 9 is positioned, the positioning cylinder module 146 controls the limiting post assembly 147 to rise and sequentially pass through the fixing sleeve assembly 144 and the slide table 8 to insert into the double-hole positioning port 145. At the same time, the two side positioning cylinders 14 8 pushes the two side pressure plates 149 respectively, so that the two side pressure plates 149 press the positioning fixture 9 from above, thereby fixing the positioning fixture 9 on the slide table 8. When it is necessary to replace the positioning fixture 9 to position different car armrest box parts, the positioning cylinder module 146 controls the limit post assembly 147 to retract into the fixing sleeve assembly 144, and the two side positioning cylinders 148 control the two side pressure plates 149 to move away from each other, thereby canceling the positioning of the positioning fixture 9, so that the positioning fixture 9 can quickly slide out from between the two guide roller assemblies 141 for disassembly and replacement.

[0038] Specifically, a first guide rail assembly 15 is fixedly connected to the central base 2, and a slide table 8 is slidably connected to the first guide rail assembly 15. A second guide rail assembly 16 is fixedly connected to the positioning fixture 9, and two clamping assemblies 10 are slidably connected to the second guide rail assembly 16. A third guide rail assembly 17 is fixedly connected to the two clamping assemblies 10, and two positioning frames 13 are slidably connected to the third guide rail assembly 17.

[0039] In this embodiment, the slide table 8 slides on the central base 2 via the first guide rail assembly 15, the two clamping assemblies 10 slide on the positioning fixture 9 via the second guide rail assembly 16, and the two positioning frames 13 slide on the two clamping assemblies 10 via the third guide rail assembly 17. The first guide rail assembly 15, the second guide rail assembly 16, and the third guide rail assembly 17 can respectively ensure the stability of the slide table 8, the two clamping assemblies 10, and the two positioning frames 13 when they move.

[0040] Specifically, a feeding baffle 18 is fixedly connected inside the chassis 22, and the feeding baffle 18 corresponds to the positioning fixture 9.

[0041] In this embodiment, the feeding baffle 18 is set at the feeding port at the front end of the chassis 22, forming a safe feeding space at the feeding port to ensure the safety of the staff when feeding materials.

[0042] Specifically, a grating sensor module 23 is fixedly connected inside the chassis 22, and the grating sensor module 23 corresponds to the feeding baffle 18.

[0043] In this embodiment, the grating sensor module 23 corresponds to the feeding baffle 18 and can detect when the worker is feeding materials, thus preventing the assembly machine from being accidentally started and injuring the worker, and further improving the safety of the worker when feeding materials.

[0044] Working principle: The positioning fixture 9 is slidably mounted on the slide table 8 via two guide roller sets 141, so that the double-hole positioning groove 142 corresponds to the positioning post assembly 143 for positioning. After the positioning fixture 9 is positioned, the positioning cylinder module 146 controls the limit post assembly 147 to rise and sequentially pass through the fixing sleeve assembly 144 and the slide table 8 to insert into the double-hole positioning port 145. At the same time, the two side positioning cylinders 148 push the two side pressure plates 149 respectively, so that the two side pressure plates 149 press the positioning fixture 9 from above, thereby fixing the positioning fixture 9 on the slide table 8. When assembling the car armrest box parts, the car armrest is placed in the material outlet at the front end of the housing 22. The armrest box component is placed on the positioning fixture 9. Two telescopic cylinders 11 control two clamping components 10 to clamp the armrest box component. Two lifting cylinders 12 control two positioning frames 13 to move down and press the armrest box component, thus fixing the armrest box component on the positioning fixture 9. Two vibrating feeder modules 3 feed the components. The reduction motor 241 controls the gear 242 to rotate. The gear 242, through meshing with the rack 243, drives the slide table 8 to slide on the central base 2. The slide table 8 drives the positioning fixture 9 to move between the four robotic arms 4, so that the armrest box component corresponds to the four robotic arms 4. The four robotic arms 4 are connected by belts. Four rotating material handling hands 5 move and rotate, causing four magnetic suction rod assemblies 6 to magnetically grab parts from the two vibrating feeder modules 3 and assemble them onto the car armrest box component. During the assembly process, four vision industrial cameras 7 inspect the parts on the four magnetic suction rod assemblies 6. The first vision inspection camera module 19, the second vision inspection camera module 20, and the third vision inspection camera module 21 inspect the assembly positioning of the parts on the car armrest box component from the front, back, left, right, and top, respectively. After the inspection is completed, the reduction motor 241 controls the gear 242 to rotate in the reverse direction, causing the slide table 8 to move the positioning fixture 9. When the component moves to the discharge port, two lifting cylinders 12 lift the two positioning frames 13, and two telescopic cylinders 11 push the two clamping components 10 away, thus releasing the fixation of the car armrest box component and allowing the car armrest box component to be taken out from the discharge port. When it is necessary to replace the positioning fixture 9 to position and assemble different car armrest box components, the positioning cylinder module 146 controls the limit post assembly 147 to retract into the fixing sleeve assembly 144, and the two side positioning cylinders 148 control the two side pressure plates 149 to move away from each other, thereby releasing the positioning of the positioning fixture 9 and allowing the positioning fixture 9 to quickly slide out from between the two guide roller assemblies 141 for disassembly and replacement.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
