Technical Field

[0001] This invention belongs to the field of motor assembly technology, specifically relating to an automated assembly and inspection line for vibration motors and its implementation method. Background Technology

[0002] The assembly process of a vibration motor requires welding the upper and lower ends. During the assembly process, it is necessary to ensure high precision in the concentricity between the inside of the housing and the mass block, and the assembly process is quite complex.

[0016] Furthermore, in this invention, the method for implementing an automated assembly and inspection line for vibration motors includes the following steps:

[0017] (I) First Machine: Manually, a material plate filled with machine shells is placed into the machine shell feeding mechanism. The hopper mechanism of the machine shell feeding mechanism picks up a single machine shell and places it into a fixture. During the placement of the machine shell, the fixture opening and closing mechanism needs to open the fixture. After the machine shell is placed, the fixture is conveyed to the mass block feeding mechanism via the first conveyor belt. The hopper mechanism of the mass block feeding mechanism picks up mass block assemblies and places them into the fixture. During the placement of the mass block assemblies, the fixture opening and closing mechanism of the mass block feeding mechanism needs to open the fixture. After the mass block assemblies are placed, the fixture passes through the first multi-station turnover mechanism. The spring sheet is transferred to the height measuring mechanism for height measurement and then to the first spring sheet assembly mechanism for spring sheet placement. The spring sheet cutting mechanism and the robot material handling mechanism cut and vacuum pick up the spring sheet, and the CCD calculates the current position of the spring sheet and the fixture. The spring sheet is then placed into the fixture and transferred to the welding pressure head mechanism for welding of the spring sheet and the mass block assembly. The first CCD detection mechanism checks whether the spring sheet is welded OK. Defective products are discharged from the first row of defective products, and qualified products are rotated 180° by the fixture flipping mechanism.

[0018] (ii) Second machine: The fixture is transferred to the second spring sheet assembly mechanism through the second multi-station turnover mechanism to place the lower spring sheet and complete the welding of the lower spring sheet. Defective products are discharged by the second defective mechanism, and qualified products are picked up by the mold removal mechanism and placed on the fourth conveyor belt. The fixture base is transported to the sixth conveyor belt through the fifth conveyor belt for buffer return.

[0019] (III) Third machine: The jig that has completed the welding of the upper and lower spring plates is transferred to the seventh conveyor belt for buffering. The end cover jig is fed by the eleventh conveyor belt. The end cover jig, end cover and jig body are assembled manually. After completion, the assembled jig is placed on the twelfth conveyor belt and transferred to the welding positioning mechanism to complete the spot welding of the end cover. The assembled jig after spot welding is disassembled manually. The end cover jig is placed on the eighth conveyor belt for return. The jig body is placed on the product picking mechanism. The assembled product is placed on the multi-station turntable mechanism by the transverse feeding mechanism. The empty jig body is returned by the thirteenth conveyor belt. The jig body and jig base are closed by the mold closing mechanism.

[0020] (iv) The multi-station turntable mechanism rotates clockwise and sequentially performs external dimension inspection, internal cavity dimension inspection, resistance inspection, laser marking and barcode scanning on the assembled products. Then, the fixture is opened and closed by the fixture loosening mechanism, and the finished products are taken out by the second hopper mechanism. Defective products are discharged by the product defect discharge mechanism.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention integrates the assembly and testing processes of the vibration motor onto the first, second, third and fourth machine tools respectively, and the first, second, third and fourth machine tools are arranged side by side in sequence, which reduces the gaps between each machine tool in the prior art and effectively reduces the space occupied.

[0023] 2. This invention achieves welding assembly of the upper and lower ends of the housing by flipping the fixture, ensuring the high precision requirement of concentricity between the housing and the mass block assembly. Compared with the prior art which requires multiple positioning of the housing, this invention improves the assembly efficiency.

[0024] 3. This invention also enables the detection of external dimensions, internal dimensions, resistance, laser marking, and barcode scanning of the completed welded and assembled products, realizing the integration of casing welding and assembly, ensuring assembly efficiency, and reducing labor intensity.

[0025] 4. The present invention achieves automated feeding of the housing and the mass block assembly by setting up the housing feeding mechanism and the mass block feeding mechanism.

[0026] 5. The present invention realizes automatic feeding and welding of spring sheets through the setting of the spring sheet assembly mechanism.

[0091] (I) First Machine: Manually, a material plate filled with machine casings is placed into the machine casing feeding mechanism 5. The hopper mechanism 51 of the machine casing feeding mechanism 5 picks up a single machine casing and places it into the fixture 46. During placement, the fixture opening and closing mechanism 53 opens the fixture 46. After the machine casing is placed, the fixture 46 is conveyed to the mass block feeding mechanism 6 via the first conveyor belt 52. The hopper mechanism of the mass block feeding mechanism 6 picks up mass block assemblies and places them into the fixture 46. During placement, the fixture opening and closing mechanism of the mass block feeding mechanism 6 opens the fixture 46. After the mass block assemblies are placed, the fixture 46 passes through the first multi-station turnover mechanism. 8. The spring sheet is transferred to the height measuring mechanism 7 for height measurement and detection, and then transferred to the first spring sheet assembly mechanism 12 for spring sheet placement. The spring sheet cutting mechanism 126 and the robot material handling mechanism 125 complete the cutting and vacuum suction of the spring sheet, and use CCD to calculate the current position of the spring sheet and the fixture 46. The spring sheet is placed into the fixture 46, and then transferred to the welding pressure head mechanism 122 to complete the welding of the spring sheet and the mass block assembly. The first CCD detection mechanism 123 detects whether the spring sheet is welded OK. Defective products are discharged by the first row of defective products mechanism 10, and qualified products are rotated 180° by the fixture flipping mechanism 9.

[0092] (II) Second machine: Fixture 46 is transferred to the second spring sheet assembly mechanism 15 through the second multi-station turnover mechanism 14 to place the lower spring sheet and complete the welding of the lower spring sheet. Defective products are discharged by the second row of defective products mechanism 16, and qualified products are picked up by the mold removal mechanism 18 and placed on the fourth conveyor belt 17. Fixture base 461 is transported to the sixth conveyor belt 21 through the fifth conveyor belt 19 for buffer return.

[0093] (III) Third machine: The jig that has completed the welding of the upper and lower spring plates is transferred to the seventh conveyor belt 22 for buffering. The end cover jig is fed by the eleventh conveyor belt 30. The end cover jig, end cover and jig body 462 are assembled manually. After completion, the assembled jig is placed into the twelfth conveyor belt 31 and transferred to the welding positioning mechanism 25 to complete the spot welding of the end cover. The assembled jig after spot welding is disassembled manually. The end cover jig is placed into the eighth conveyor belt 26 for return. The jig body 462 is placed into the product picking mechanism 33. The assembled product is placed into the multi-station turntable mechanism 41 by the transverse feeding mechanism 35. The empty jig body 462 is returned through the thirteenth conveyor belt 32. The jig body 462 and jig base 461 are closed by the mold closing mechanism 20.

[0094] (iv) The multi-station turntable mechanism 41 rotates clockwise to sequentially inspect the external dimensions, internal dimensions, resistance, laser marking, and barcode scanning of the assembled products. Then, the fixture is opened and closed by the fixture loosening mechanism 38, and the finished products are taken out by the second hopper mechanism 37. Defective products are discharged by the product defect discharge mechanism 36.

[0095] In summary, this invention integrates the assembly and testing processes of the vibration motor onto the first machine tool 1, the second machine tool 2, the third machine tool 3, and the fourth machine tool 4, respectively. These four machine tools are arranged side-by-side, reducing gaps between machine tools in existing technologies and effectively minimizing space requirements. By flipping the fixture 46, this invention achieves welding assembly of the upper and lower ends of the housing, ensuring high-precision concentricity between the housing and the mass block assembly. Compared to existing technologies requiring multiple positioning of the housing, this improves assembly efficiency. This invention also enables external dimension inspection, internal cavity dimension inspection, resistance inspection, laser marking, and barcode scanning of the completed welded assembly, achieving integrated housing welding assembly, ensuring assembly efficiency, and reducing labor intensity. The housing feeding mechanism 5 and the mass block feeding mechanism 6 automate the feeding of the housing and mass block assembly. The spring sheet assembly mechanism automates the feeding and welding of the spring sheets. The fixture of this invention can achieve precise positioning of the housing, ensuring high-precision turnover requirements.

Defective products are discharged from the first row of defective products, and qualified products are rotated 180° by the fixture flipping mechanism. (ii) Second machine: The fixture is transferred to the second spring sheet assembly mechanism through the second multi-station turnover mechanism to place the lower spring sheet and complete the welding of the lower spring sheet. Defective products are discharged by the second defective mechanism, and qualified products are picked up by the mold removal mechanism and placed on the fourth conveyor belt. The fixture base is transported to the sixth conveyor belt through the fifth conveyor belt for buffer return. (III) Third machine: The jig that has completed the welding of the upper and lower spring plates is transferred to the seventh conveyor belt for buffering. The end cover jig is fed by the eleventh conveyor belt. The end cover jig, end cover and jig body are assembled manually. After completion, the assembled jig is placed on the twelfth conveyor belt and transferred to the welding positioning mechanism to complete the spot welding of the end cover. The assembled jig after spot welding is disassembled manually. The end cover jig is placed on the eighth conveyor belt for return. The jig body is placed on the product picking mechanism. The assembled product is placed on the multi-station turntable mechanism by the transverse feeding mechanism. The empty jig body is returned by the thirteenth conveyor belt. The jig body and jig base are closed by the mold closing mechanism. (iv) The multi-station turntable mechanism rotates clockwise and sequentially performs external dimension inspection, internal cavity dimension inspection, resistance inspection, laser marking and barcode scanning on the assembled products. Then, the fixture is opened and closed by the fixture loosening mechanism, and the finished products are taken out by the second hopper mechanism. Defective products are discharged by the product defect discharge mechanism.
