Technical Field

[0001] The present invention relates to the field of automated production lines, and in particular, to a universal automated assembly line. Background Art

[0002] In the production process of some products, it is necessary to process and assemble their various components. At present, due to differences in function and quality, the same type of products on the market are usually divided into different models and assembled separately. For example, electric irons usually require the assembly of the soleplate cover, vaporization chamber, vaporization chamber cover and other parts. In addition, products under the same brand usually have multiple models. There are both the same and different assembly processes between different models. In order to facilitate processing, current manufacturers usually set up a separate assembly production line for different models of products, which will lead to a significant increase in costs. Summary of the invention

After the vaporization chamber cover is oiled, it is grabbed into the first screw locking device, and the semi-finished product is screwed in the first screw locking device, and then the semi-finished product with screws locked is placed in the second circulation module. Secondly, the semi-finished product that has been assembled in the cover body in the second circulation module is grabbed by the material transfer device and transferred to the riveting device for riveting. After riveting, the semi-finished product enters the heating and insulation withstand voltage detection device, the vaporization promotion coating device, the cooling device and the pressure leakage detection device in turn, thereby completing the assembly and testing of the product.

The transfer robot a433 is arranged at the end of the transfer linear module a431, and is used to transfer the welded product located in the welding fixture a421 to the transfer fixture a432. At this time, the transfer linear module a431 drives the welded product to move to the other end, waiting to be grabbed by the transfer device 1 to enter the next process.

[0047] The terminal feeding mechanism a44 includes a terminal vibration disk a441, a material dividing belt a442 provided at the output end of the terminal vibration disk a441, and a terminal material taking manipulator a443 for grabbing the terminal, wherein the terminal material taking manipulator a443 grabs the terminal located on the terminal material dividing belt a442 into the welding jig a421.

Among them, a plurality of oiling jigs are arranged on the rotating table a53, and the oiling jigs can be divided into two groups. The rotating table a53 can realize alternating oiling of the two groups of oiling jigs by rotating, thereby effectively improving the oiling efficiency of the vaporization chamber. Among them, the number of oiling jigs, the number of suction devices and the number of oilers a55 in each group are the same.

[0050] Specifically, the front-end assembly line A is equipped with two material transfer devices 1. This embodiment is illustrated by taking the front-end assembly of different series of electric irons as an example: FS machine: manually place the processed semi-finished gasification chamber into the welding fixture a421 on the first turntable a42, the terminal feeding mechanism a44 grabs the terminal into the welding fixture a421, and the welding mechanism a45 welds and inspects the terminal and the semi-finished gasification chamber; then the transfer device 1 grabs the welded gasification chamber into the semi-finished oiling device a5 for oiling, and detects the oiling effect through the camera, and the defective products are placed in the defective product collection box; at the same time, the transfer device 1 grabs the bottom plate cover from the first bottom plate cover feeding platform a3 to the first circulation module a1, and assembles the oiled gasification chamber into the bottom plate cover, forming a semi-finished assembly of the bottom plate cover and the gasification chamber, and then transfers to the next process.

The oiling effect is detected by the camera, and the defective products are placed in the defective product collection box; at the same time, the transfer device 1 grabs the bottom plate cover from the first bottom plate cover feeding platform a3 to the first circulation module a1, and assembles the oiled gasification chamber into the bottom plate cover to form a semi-finished assembly of the bottom plate cover and the gasification chamber, and then flows to the next process. This is the front-end processing and assembly process of the GHK model.

[0052] Other models: Other models do not require oiling or assembly of the bottom plate cover and the vaporization chamber. The processed semi-finished products can be directly placed into the first circulation module a1 manually and enter the next process.

[0053] It should be noted that, in order to facilitate the transportation and positioning of products, a product fixture for placing products is also provided on the first circulation module a1.

[0055] The assembly process of the middle section assembly line B is as follows: the material transfer device 1 grabs the semi-finished product assembled by the front section assembly line A into the first screw locking device b2, and then grabs the vaporization chamber cover from the cover body feeding platform b3 to the cover body oiling device b4 for oiling. After the vaporization chamber cover is oiled, it is grabbed into the first screw locking device b2, and the semi-finished product is screwed in the first screw locking device b2, and then the semi-finished product with screws locked is placed in the second circulation module b1. Secondly, the semi-finished product that has been assembled in the cover body in the second circulation module b1 is grabbed by the material transfer device 1, and transferred to the riveting device b5 for riveting. After riveting, the semi-finished product can be stored online on the transfer table b10, and then enters the heating and insulation withstand voltage detection device b6, the vaporization promotion coating device b7, the cooling device b8 and the pressure leakage detection device b9 in sequence, thereby completing the assembly and testing of the product.

At this time, the screw locking robot drives the intelligent electric screwdriver to move to the screw locking jig b221 to perform the screw locking operation on the product. The positioning camera and light source can accurately position the product.

[0057] The first screw locking device b2 of this embodiment adopts a double-station processing method, that is, two screw locking mechanisms b23 are arranged on the edge of the second turntable b22, which can realize uninterrupted processing of the first screw locking device b2, which can effectively save space and improve the screw locking efficiency of the product.

When performing the riveting operation of the product, the product is grabbed from the second flow module b1 to the first slide b522 through the material transfer device 1, and a fixture for positioning the product can be provided on the first slide b522, and then the first driving member b523 drives the first slide b522 to move into the riveting machine b51 for riveting, and after the riveting is completed, the product is transferred to the transfer table b10.

[0059] By integrating the first feeding mechanism b52, automatic feeding of the riveting machine b51 is achieved, which facilitates the grabbing and placement of the material transfer device 1. The material transfer device 1 does not need to extend into the interior of the riveting machine b51 to complete the loading.

[0063] Multiple products can be placed on the cooling conveyor line b82. In addition, by setting a cooling cover b83 above the cooling conveyor line b82 and installing multiple fans b84, all-round and efficient cooling of the products is achieved. The forced convection of the fan b84 accelerates the air flow, effectively reduces the product temperature, shortens the cooling time, and improves production efficiency.

[0064] Please refer to Fig.12 In this embodiment, the pressure leakage detection device b9 includes a fifth machine platform b91, on which a test upper mold b93 and a third slide rail b92 are provided. A test lower mold b94 is provided on the third slide rail b92. The test lower mold b94 can be moved to the bottom of the test upper mold b93 driven by the third slide rail b92. At this time, the test upper mold b93 can be pressed onto the test lower mold b94, thereby completing the pressure leakage detection of the product.

[0065] It should be noted that the cover body oiling device b4 of this embodiment is similar in structure to the semi-finished product oiling device a5, and the jig and the oiling position can be flexibly adjusted according to the actual parts that need to be oiled. The gasification-promoting coating device b7 is an existing device, and in order to adapt to the processed products, only the water supply and wastewater recovery need to be modified. For example, a centralized clean water tank is added to transport water to the clean water tank of each machine, and a level sensor is added to the clean water tank of each machine. When there is a lack of water, the water pump pumps water into the clean water tank of the equipment. A centralized wastewater tank is added to pump the water in the wastewater tank of each device into the centralized wastewater tank. A liquid level sensor is added to the wastewater tank of each machine, and when the water is full, the water pump pumps water into the centralized wastewater tank.

[0066] Specifically, this embodiment takes the middle section assembly of different series of electric irons as examples for explanation.

[0067] FS and GHK models: The material transfer device 1 grabs the product from the first circulation module a1 to the first screw locking device b2. At the same time, the material transfer device 1 grabs the vaporization chamber cover from the cover body feeding platform b3 to the cover body oiling device b4 for oiling. After the oiling is completed, the vaporization chamber cover is grabbed to the first screw locking device b2, and then the above product is screwed. After the screw locking is completed, the product is transferred to the second circulation module b1. Then, the product is riveted, heated and tested for insulation withstand voltage, vaporization promotion coating, cooled, and tested for pressure leakage.

[0068] Other models: Unlike the above two models, other models do not require the step of locking screws. Therefore, the product is grabbed from the first circulation module a1 to the second circulation module b1 through the material transfer device 1, and at the same time, the material transfer device 1 grabs the vaporization chamber cover from the cover body feeding platform b3 to the cover body oiling device b4 for oiling. After the oiling is completed, it is transferred to the second circulation module b1 for assembly. Then, the product is riveted, heated and tested for insulation withstand voltage, vaporization promotion coating, cooled, and tested for pressure leakage.

[0069] Please refer to Figure 1 In this embodiment, the rear assembly line C includes a third circulation module c1, and a second bottom plate cover feeding platform c2, a bottom plate cover oiling device c3, and a second screw locking device c4 distributed on the side of the third circulation module c1. Specifically, the bottom plate cover oiling device c3 is similar in structure to the semi-finished product oiling device a5 or the cover body oiling device b4, and the mold and the oiling position can be flexibly adjusted according to the actual product that needs to be oiled. For example, the bottom plate cover oiling device c3 does not need the flipping mechanism a54 to flip, and the flipping mechanism a54 can be omitted. Similarly, the second screw locking mechanism b23 is similar in structure to the first screw locking device b2, and the positions of the second turntable b22 and the screw locking mechanism b23 can be flexibly adjusted according to the actual product that needs to be screwed.

[0070] It should be noted that the rear-end assembly line C is an adjustment of the function of the front-end assembly line A. That is, in the assembly of the second product series, the base plate cover needs to be oiled. Therefore, the assembly of the base plate cover and the vaporization chamber is cleverly placed in the rear-end assembly line C, thereby further improving the applicability of the overall assembly line.

[0071] Specifically, this embodiment takes the rear-end assembly of different series of electric irons as examples for explanation.

[0072] Models W, WL and GHF025: The bottom plate cover of this series of products also needs to be oiled, so it is not suitable for the products assembled in the assembly process of the front-end assembly line A. Therefore, the bottom plate is not assembled first, and the products are assembled according to the normal middle-stage assembly line B. Later, the bottom plate applicable to this type of product is grabbed from the second bottom plate cover feeding platform c2 to the bottom plate cover oiling device c3 through the material transfer device 1 for oiling. After oiling, the bottom plate cover is grabbed into the second screw locking device c4, and then the semi-finished product in the pressure leakage test device is grabbed into the second screw locking device c4, and then the above products are screwed. After the screw locking is completed, it is transferred to the third flow module c1 for discharge.

[0073] Other models: For other series of products, it is only necessary to transfer the products in the pressure leakage test device to the third flow module c1 for discharge.
