Description

Technical Field

[0001] This utility model relates to the field of positioning equipment technology, and in particular to a detachable base for a four-axis robot buckle assembly device. Background Technology

[0002] In the manufacturing of electronic components and automotive parts, snap-fit ​​connections are widely used in the assembly processes of various products due to their convenient assembly and low cost. With the increasing demand for automated production, four-axis robots, with their flexible operating precision and efficient operation capabilities, have gradually become the core execution equipment in snap-fit ​​assembly processes. As the core positioning component of four-axis robot snap-fit ​​assembly equipment, the ease of disassembly and assembly, positioning accuracy, and operational stability of the base directly determine the overall production efficiency and product qualification rate of the assembly process. Currently, the bases used with four-axis robot buckle assembly equipment on the market have insufficient positioning accuracy, resulting in a high scrap rate. Existing bases lack effective limiting and detection auxiliary structures. The docking and positioning of the base and the platform mainly rely on manual visual calibration. Workers need to repeatedly adjust the position of the base to ensure that the docking platform of the assembly part is aligned with the robot's clamping path. However, manual calibration is easily affected by operating experience and visual errors, making it difficult to guarantee positioning accuracy. In actual production, the buckle and the docking platform are often misaligned due to base offset, which not only causes buckle damage and scratches on the assembly part, but also keeps the product scrap rate at a high level of 5%-8%, increasing production costs. Therefore, the above problems need to be improved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4This utility model discloses a detachable base for a four-axis robot snap-fit ​​assembly device, comprising a base plate 6 installed on one side of the top surface of a base 1. The base 1 facilitates the support of subsequent components. The base 1 also houses pneumatic and control components. The base plate 6 facilitates the connection of handles 7 and a placement platform 8 with external components and secures itself to the base 1. Handles 7 are installed at the front and rear ends of the top surface of the base plate 6. A placement platform 8, located in the middle of the top surface of the base plate 6, is installed between the proximal ends of the two handles 7. The handles 7 facilitate the quick replacement of the movable base plate 6 and the various components installed on the top surface of the base plate 6. The placement platform 8 in the middle of the top surface of the base plate 6 facilitates the use of external grooving processes and opening... The process includes creating a first vent hole 9, a second vent hole 10, a constant pressure hole 12, an exhaust groove 11, and a placement groove. The placement platform 8 uses the placement groove to limit the subsequent assembly of the main body 13. The substrate 6 is equipped with disassembly and assembly components for easy connection to the base platform 1. A receiving mechanism 2 is installed on one side of the front end of the top of the base platform 1, which facilitates the subsequent guidance and collection of the clips 14 of the feeding structure 3. A feeding mechanism 3 is installed on the other side of the receiving mechanism 2, which facilitates the collection and adjustment of the clips 14 of the transport and feeding mechanism 4 and their transport to the receiving mechanism 2. A feeding mechanism 4 is installed on one side of the feeding mechanism 3, which facilitates the subsequent pouring of the required clips 14 by external personnel for transport to the feeding machine. The feeding mechanism 3 is equipped with a robotic arm positioning mechanism 5 at its rear end. This mechanism facilitates the subsequent clamping and transport of the buckle 14 located at the receiving mechanism 2 to the clamping platform of the assembly body 13 by the built-in air pump assembly of the base 1. The base 1 has multiple air supply holes, mounting holes, and limiting holes equidistantly connected on one side of its rear end. The placement platform 8 has placement grooves at both its front and rear ends. Each of the two placement grooves has a first vent hole 9 on both sides of the same end. A positioning hole connecting the placement platform 8 and cooperating with the air supply holes is located between the two first vent holes 9 at the same end. This positioning hole facilitates the subsequent installation of air nozzles and pneumatic components to fix the assembly body 13 placed in the placement groove. A second vent hole 10 is provided between the two first vent holes 9 to connect the placement platform 8. The front and rear ends of the bottom of the placement platform 8 are provided with exhaust grooves 11 that connect the first vent holes 9 and the second vent holes 10. The front and rear ends of the other side of the placement platform 8 are respectively provided with constant pressure holes 12 that connect the exhaust grooves 11. The first vent hole 9, the second vent hole 10, the exhaust grooves 11 and the constant pressure holes 12 facilitate the transmission of compressed air generated by the downward pressure when the assembly body 13 is placed on the placement platform 8 through the placement grooves to the exhaust grooves 11, and then the air is discharged through the constant pressure holes 12. Finally, the assembly body 13 is fixed with the help of pneumatic components and air nozzles installed in the positioning holes. In this invention, the front and rear ends of the placement platform 8 are respectively equipped with the assembly body 13 that matches the placement slot. The top surface of the assembly body 13 has multiple waiting docking platforms, and the assembly body 13 is fitted with multiple buckles 14 that engage with the waiting docking platforms. The buckles 14 facilitate the engagement of the robotic arm positioning mechanism 5 with the waiting docking platforms provided on the assembly body 13. The disassembly and assembly components include limiting platforms 15 located at the rear end of one side and the front end of the other side of the substrate 6. The proximal ends of the two limiting platforms 15 abut against the bottom surface of the substrate 6, and the limiting platforms 15 facilitate the disassembly and assembly of the substrate 6. The limit position prevents loosening from the base 1; the limit position 15 is installed on the base 1 by bolts and limit holes, and the top surface of the base 1 is equipped with a detection platform 16 with matching installation holes. The detection platform 16 facilitates the subsequent installation of the laser sensor 17 through external limit components; the detection platform 16 has two detection holes connected to it, the detection holes are aligned with the substrate 6, and the detection platform 16 is equipped with a laser sensor 17 that matches the detection holes. The laser sensor 17 facilitates the detection of whether the substrate 6 has reached the correct predetermined position. The model of the laser sensor 17 is HL-G108-SJ.

[0015] Working principle: When using this utility model, the operator first checks whether the transmission components of the receiving mechanism 2, feeding mechanism 3, and feeding mechanism 4 are flexible and whether the clamping part of the robotic arm positioning mechanism 5 is intact. Then, the operator moves the base placement assembly to the rear end of the top surface of the base 1 by holding the handles 7 at the front and rear ends of the substrate 6. During the placement process, it is necessary to ensure that the bottom surface of the substrate 6 abuts against the limiting platform 15 on the base 1 so that the limiting platform 15 can limit the horizontal displacement of the substrate 6 and prevent the substrate 6 from shifting during the assembly process. At the same time, the operator fixes the detection platform 16 through the mounting holes using external components. It is necessary to manually confirm whether the two detection holes are aligned with the substrate 6. Then, the operator installs the laser sensor 17. After the installation is completed, power is supplied to the equipment, and the laser sensor 17 is activated. The laser sensor 17 emits a laser through the detection hole to determine whether the substrate 6 is in place. If the signal is abnormal, the position of the substrate 6 needs to be readjusted until the laser sensor 17 confirms accurate positioning. Then, the workers pour the buckles 14 to be assembled into the feeding mechanism 4 in batches. After sorting, the feeding mechanism 4 conveys the buckles 14 to the feeding mechanism 3. The feeding mechanism 3 transports the buckles 14 to the receiving mechanism 2 via the built-in conveyor belt. The receiving mechanism 2 temporarily stores the buckles 14 through the positioning groove or guide plate to ensure that the position of each buckle 14 is aligned with the clamping path of the robot positioning mechanism 5. Then, the workers place the assembly body 13 into the placement grooves at the front and rear ends of the top of the placement table 8. The placement grooves can restrict the displacement of the assembly body 13 in the direction perpendicular to the plane of the placement table 8 (during the process of placing the assembly body 13 into the placement groove, the assembly body 13 will squeeze the air in the groove when it presses down on the placement groove, and some of the air will be released). Air enters the exhaust groove 11 through the first vent hole 9 and the second vent hole 10 on both sides of the same end of the placement groove, and is finally discharged through the constant pressure hole 12 connected to the exhaust groove 11. This prevents the assembly body 13 from not being able to fit the placement platform 8 due to air pressure buildup in the placement groove, and balances the air pressure inside and outside the placement platform 8 to ensure stable pneumatic adsorption force. Then, the operator activates the pneumatic component in the inner cavity through the control component installed on the base 1 to provide negative pressure to the air nozzle in the positioning hole, thereby generating an adsorption force on the assembly body 13 in the placement groove and fixing the assembly body 13. After fixing, the operator sends a command to the robot positioning mechanism 5 through the control component installed on the base 1. The robot positioning mechanism 5 moves to the receiving mechanism 2 according to the preset program, accurately clamps the temporarily stored buckle 14, moves it to the assembly body 13 above the placement platform 8, aligns the buckle 14 with the receiving platform on the top surface of the assembly body 13, and then applies downward pressure to make the buckle 14 and the receiving platform complete the snap-fit ​​fixing. This process can be repeated.
