Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly, in particular to an assembly and screw locking device. Background Art

[0002] In the process of manufacturing various products, it is often necessary to assemble small spare parts (materials) with the products and fasten them with screws. Existing technologies often first perform assembly through different workstations and then send them to the next workstation for fixed locking. However, such spare parts are often very small, making manual assembly difficult, with low precision and efficiency. At the same time, after assembly, small screws still need to be manually locked; both manual feeding and locking of small screws are difficult, with poor locking precision and quality, and the locking standard cannot be controlled. In this way, a large amount of manpower is also required for assembly and locking, resulting in a low output ratio and a low yield. Summary of the Utility Model

[0037] Please refer to Figures 1 to 7 , an assembly and screw-locking device 100 is provided in an embodiment of the present application. The assembly and screw-locking device 100 includes: a material feeding mechanism 1, a product feeding mechanism 2, a material assembly mechanism 3, and a screw-locking mechanism 4. Among them, the material feeding mechanism 1 is used to provide materials to be assembled to the product. The product feeding mechanism 2 is used to provide products to be assembled with the materials. The material assembly mechanism 3 is arranged between the material feeding mechanism 1 and the product feeding mechanism 2, and is used to pick up materials from the material feeding mechanism 1 and rotate and assemble the materials onto the products on the product feeding mechanism 2. The screw-locking mechanism 4 includes a screw feeding mechanism 41 and a screw locking mechanism 42. The screw locking mechanism 42 is used to suck screws from the screw feeding mechanism 41 and lock the screws onto the materials and the products.

[0038] The assembly and screw-locking device 100 provided in the embodiment of the present application integrates assembly and locking in the same work station, solves the problems that after the material assembly is completed, it is necessary to move to the next station or the next device for locking, and the assembled materials are offset or dropped during the moving process; improves the assembly and locking quality, and the yield is greatly improved. Through the precise assembly of the material assembly mechanism 3, the automatic supply of screws by the screw feeding mechanism 41, and the automatic screw locking by the screw locking mechanism 42, it solves the problems of low manual production efficiency, difficult manual access to screws, and difficult screw locking, and improves the screw-locking efficiency and quality.

[0039] In a feasible implementation, the material assembly mechanism 3 includes an assembly robot 31 and a first identification mechanism 32. The assembly robot 31 is used to pick up the screw and deliver it to the first identification mechanism 32 for position identification, and then perform alignment and locking. Among them, the assembly robot 31 includes a robotic arm 311 and a robot hand 312. The robotic arm 311 is used to drive the robot hand 312 to rotate around the tip of the material, and insert the material into the installation groove of the product to achieve assembly.

[0040] In a feasible implementation, the robotic arm 311 is a six-axis robotic arm 311. The six-axis robotic arm 311 can flexibly position the end effector in three-dimensional space and reach complex working positions, which is particularly important for tasks involving irregular shapes or working in confined spaces. High-precision servo motors and advanced control systems enable the six-axis robotic arm 311 to achieve very precise positioning and repeated positioning. Through automated operation, the six-axis robotic arm 311 can work continuously, reduce human errors, increase production speed and consistency, thereby improving overall production efficiency. Contemporary six-axis robotic arms 311 are usually equipped with user-friendly programming interfaces and software, enabling operators to easily program and debug, and at the same time being easy to integrate with other automated equipment to form an efficient production line. In the long run, the six-axis robotic arm 311 can reduce labor costs, lower the scrap rate, and increase production efficiency, thus bringing considerable cost savings to the enterprise. The modern six-axis robotic arm 311 is designed with maintenance convenience in mind, and many components can be quickly disassembled and replaced, reducing downtime.

[0041] In a feasible implementation, as Figures 1 to 4 shown, the robot hand 312 is provided with a laser displacement sensor 313, a second identification mechanism 314, and a suction nozzle assembly 315. The laser displacement sensor 313 is used to determine the height of the material in the vertical direction. The second identification mechanism 314 is used to determine the position of the material in the horizontal direction, and the suction nozzle assembly 315 is used to suck the material. The second identification mechanism 314 includes a third CCD camera.

[0042] In a feasible implementation, as Figures 1 to 4As shown, the nozzle assembly 315 includes a suction head 3151, a first pressure sensor 3152, a first elastic element 3153, and a first connecting member 3154. The first connecting member 3154 is connected to the robotic arm 311. The first elastic element 3153 is disposed between the first connecting member 3154 and the first pressure sensor 3152. The first elastic element 3153 is used to buffer the force transmitted from the first connecting member 3154 to the suction head 3151. The pressure sensor is disposed between the suction head 3151 and the first elastic element 3153, and the suction head 3151 is connected to the detection end of the first pressure sensor 3152. In this way, the nozzle assembly 315 can achieve a flexible connection with the material. At the same time, when assembling the material with the product, it can also contact the product flexibly, avoiding damage to the material or the product.

[0043] Further, as Figures 1 to 4 shown, the nozzle assembly 315 further includes a second connecting member 3155 and a first guiding slide rail 3156. The first guiding slide rail 3156 is disposed on the second connecting member 3155 in the vertical direction. The first connecting member 3154 is slidably connected to the robotic arm 311 through the second connecting member 3155, and the suction head 3151 is slidably connected to the second connecting member 3155 through the first guiding slide rail 3156. The second connecting member 3155 is provided with a sliding groove, and the first connecting member 3154 is slidably connected in the sliding groove. In this way, the movement of the suction head 3151 and its contact with the material can be guided and buffered, avoiding damage to the material or the product.

[0044] In a feasible implementation manner, as Figures 1 to 6As shown, the assembly and screw locking device 100 further includes a material pressing mechanism 5. The material pressing mechanism 5 is used to press the product and the material to keep them under pressure after the material assembly mechanism 3 combines the product and the material and before the screw locking mechanism 42 locks the screws. Further, the material pressing mechanism 5 includes a positioning component 51 and a pressing head component 5252. The positioning component 51 is used to position the pressing head component 5252 in the horizontal direction. Specifically, the positioning component 51 may include a substrate 511, an X-direction module 512, and a Z-direction module 513 connected to the substrate 511. Such a combination is relatively common and will not be elaborated here. Further, the pressing head component 5252 includes: a third connecting member 521, a second elastic element 522, a second guiding slide rail 523, a second pressure sensor 524, and a pressing head 525. The third connecting member 521 is fixedly connected to the substrate 511. The second elastic element 522 is disposed between the third connecting member 521 and the second pressure sensor 524. The second pressure sensor 524 is disposed between the pressing head 525 and the second elastic element 522. The second pressure sensor 524 is slidably connected to the substrate 511 through the second guiding slide rail 523. This can enable the material pressing mechanism 5 to have a flexible contact with the material when pressing the material and the product to avoid damage. The pressure sensor detects the pressure to avoid damage caused by excessive pressure.

[0045] In a feasible implementation manner, the material feeding mechanism 1 includes: a material loading component 11, a material unloading component 12, and a transplanting component 13. Among them, the material loading component 11 is used to provide a tray full of the material to the material assembly mechanism 3, and the material unloading component 12 is used to carry an empty tray; the transplanting component 13 is used to transplant the empty tray from the material loading component 11 to the material unloading component 12.

[0046] In a feasible implementation manner, the transplanting component 13 includes a clamping jaw component 131 and a moving module 132. The clamping jaw component 131 is used to clamp the tray, and the moving module 132 is used to drive the clamping jaw component 131 to move between the material loading component 11 and the material unloading component 12.

[0047] In a feasible implementation manner, the magazine component 112 includes a belt line 1121. The belt line 1121 can be docked with the feeding or discharging streamline. In this way, it is convenient to transfer the stacked trays, saving manpower and improving production efficiency. The specific structure of the belt line 1121 can be a common belt line 1121 structure, which is not the key invention of this application and will not be elaborated here.

[0048] In a feasible implementation manner, as Figure 5As shown, the material feeding component 11 includes a lifting component 111 and a silo component 112. The lifting component 111 includes a first lifting driving member 1111, a first pallet 1112, and a first slide rail 1113. The first lifting driving member 1111 can drive the first pallet 1112 to reciprocate on the first slide rail 1113. When feeding is required, the stacked trays can enter the silo component 112 through the belt line 1121. At this time, the height of the first pallet 1112 is lower than the transmission plane of the belt line 1121 of the silo component 112. The first lifting driving member 1111 drives the first pallet 1112 to lift the stacked full trays and rise along the first slide rail 1113 until the tray at the top of the full trays is conveyed to a height where the gripper assembly 131 of the moving module 132 can grip it. Correspondingly, the material discharging component 12 is the same as or similar to the material feeding component 11, which will not be elaborated here.

[0049] In a feasible implementation manner, the product feeding mechanism 2 includes a first conveying line 21. The first conveying line 21 includes a code scanning station 211, a buffer station 212, and an assembly station 213 arranged in sequence. The assembly of the product and the material is carried out at the assembly station 213. Further, the product feeding mechanism 2 further includes a second conveying line 22. The second conveying line 22 includes a double-layer line. The upper layer of the double-layer line is a material passing line 221, and the lower layer is a return line 222. The double-layer line design allows feeding and discharging to be carried out simultaneously, reducing the waiting time and improving the logistics efficiency. The raw materials can be directly conveyed to the starting end of the production line, while the finished products or waste can be quickly removed from the other end of the production line, avoiding logistics congestion. By vertically stacking the feeding and discharging lines, more efficient material flow can be achieved in a limited space, which is particularly important for factory environments with limited space. The double-layer line design makes the layout of the production line more compact, enabling better planning and utilization of the production area, and facilitating the management and tracking of materials. In industries such as food and pharmaceuticals, separating the raw materials from the finished products can significantly reduce the risk of cross-contamination, improving product safety and quality. The upper and lower layers respectively handle different processes, facilitating the integration of automated equipment (such as robotic arms, conveyor belts, AGVs, etc.) to achieve automatic material transmission, reducing manual intervention, and improving the level of production automation. The separated logistics paths reduce the opportunity for operators to come into contact with the materials, reducing the risk of work-related injuries and facilitating the arrangement of safety facilities. The double-layer line design makes the expansion and adjustment of the production line more flexible, allowing easy adjustment of the logistics path and capacity according to changes in production requirements. By optimizing the material flow path and reducing unnecessary material handling and waiting, it helps to reduce the energy consumption of the entire production process. The specific structure of the conveying line is relatively common and is not the focus of the invention of this application, which will not be elaborated here.

[0050] In a feasible implementation manner, the first conveying streamline 21 is further provided with a re-inspection station 214. The re-inspection station 214 is arranged downstream of the assembly station 213. A re-inspection mechanism 6 is provided on the re-inspection station 214. The re-inspection mechanism 6 is used to detect whether the assembly and locking of the material and the product are qualified. The assembly and screw-locking equipment provided in this application has a simple structure. The left manipulator picks and assembles materials, and the right electric screwdriver simultaneously picks and locks screws. The material picking and assembly and screw locking are carried out alternately, with high efficiency and short CT.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0052] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
