Description

Technical Field

[0001] This invention relates to the field of automatic relay manufacturing, specifically to an automatic relay assembly machine and its assembly process. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity changes to a specified value. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit); it is commonly used in automated control circuits, and is essentially an "automatic switch" that uses a small current to control a large current; it plays roles in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] A relay's structure comprises components such as a relay core and a relay housing. The relay core is a structural component assembled from a coil, a support, etc., while the relay housing is a shell-like structure with an open bottom. The assembly of the relay core and housing is a later stage of the relay assembly process. In this process, a shim is placed under the relay core before the relay housing is inserted from above, and the connecting clips are pressed together to secure them. Furthermore, based on product traceability and identification requirements, this stage also requires scanning and recording information on the relay core and marking multiple times on the surface of the relay housing. Based on these assembly requirements, an automated relay assembly machine and its assembly process need to be designed to implement and integrate these functions. Summary of the Invention

[0014] An assembly process for an automatic relay assembly machine includes the following steps:

[0015] S1, Loading and Transfer: The relay cores and relay housings exported from the previous workstation are transported to the transfer loading platform;

[0016] S2, Relay Core Loading: The relay core on the transfer loading platform is moved to a feeding position at the core loading station by the first lifting arm;

[0017] S3, Relay Housing Loading: After the relay core is loaded in step S1, the turntable rotates to the housing loading station, and the relay housing on the transfer loading platform is moved to another loading position by the second lifting arm;

[0018] S4. Gasket Assembly and First Marking: After the relay housing is loaded in step S3, the turntable rotates to the gasket assembly station. The material handling component of the turntable mechanism clamps the relay core and lifts it upward. At the same time, the gaskets exported by the gasket loading component are transported to the material placement position of the relay core by the gasket transfer component in a back-and-forth rotation. At the same time, the first marking gun performs the first marking on the relay housing. Then the material handling component places the relay core on the gasket.

[0019] S5. Core scanning and pre-assembly: After the gasket is assembled and the first marking is completed in step S4, the turntable rotates to the scanning and pre-assembly station. The material picking and scanning mechanism lifts the relay housing upwards, and its barcode scanner scans the relay core. Then, the lifted relay housing is placed on the relay core from above to complete the pre-assembly.

[0020] S6. Pressing and Assembly and Second Marking: After the pre-assembly is completed in step S5, the turntable rotates to the second marking and assembly station. The pressing component of the marking and pressing mechanism pushes the relay core from below and then presses the relay housing from above, so that the connecting buckle of the relay core and the relay housing is fastened and fixed to each other. Then, the second marking gun of the marking and pressing mechanism marks the relay housing for the second time.

[0021] S7. Inspection and unloading: After the pressing assembly and second marking in step S6 are completed, the product is inspected by CCD camera. Good products are transported to the unloading transfer station for buffering, while defective products are transported to the NG platform for buffering.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing an automatic relay assembly machine and its assembly process. This machine combines parallel dual feeding positions with multiple assembly stations to achieve automatic and independent feeding of relay cores and housings, marking and gasket installation, barcode scanning pre-assembly, secondary marking and pressing assembly, effectively improving assembly efficiency.

[0024] This invention aims to provide a downstream process for relay manufacturing, belonging to relay automated assembly equipment. Its function is to realize the automated assembly of relay core, relay housing and gasket. At the same time, during the assembly process, it completes two markings on the relay housing and automatic barcode scanning of the relay core, and realizes the detection, classification and unloading after assembly.Specifically, this invention uses a machine as the supporting structure, and the machine is equipped with a turntable mechanism. The turntable of the turntable mechanism serves as a rotating platform, and along the circumferential direction, it is provided with a core loading station, a housing loading station, a gasket assembly station, a barcode scanning pre-assembly station, and a second marking and assembly station. It should be noted that each of the above stations is provided with two material placement positions at intervals to allow for the side-by-side placement of relay cores and relay housings before assembly. A transfer loading platform is provided on the side of the core loading station and the housing loading station. A first lifting arm and a second lifting arm are mounted on the side of the transfer loading platform. After the relay cores and relay housings exported from the previous station are transferred to the transfer loading platform by the robot arm, they are respectively processed by the first... The first and second lifting arms move the relay cores from the core loading station and the housing loading station to the unloading position. Then, the relay cores are rotated to the gasket assembly station via a turntable. At the gasket assembly station, automatic gasket assembly is achieved. During assembly, the process of lifting the relay core using the material handling component to place the gasket effectively solves the problem of interference between the relay core and the first marking of the relay housing. This also solves the problem of interference with the relay housing marking caused by parallel placement. Simultaneously, after the gaskets are automatically exported by the gasket loading component, a gasket transfer component located between the gasket loading component and the turntable achieves cyclical picking and unloading through reciprocating rotation, effectively improving the gasket... To improve assembly efficiency, after the gasket and initial marking are completed, the turntable rotates to the barcode scanning pre-assembly station. At this station, the relay core needs to be scanned, but the parallel-placed relay housings would obstruct the scanning path. Therefore, the pre-assembly and scanning actions are combined. First, the relay housing is lifted upwards before scanning the relay core. The lifted relay housing avoids obstructing the scanning. After scanning, the relay housing is then placed onto the relay core from above, completing the pre-assembly and effectively improving assembly efficiency. After pre-assembly, the turntable rotates to the second marking and assembly station, where the second marking gun performs a second marking on the relay housing. It should be noted that... Because the marking information is different, the marking needs to be done on the relay housing twice. At the same time, the pressing assembly outputs power from the top and bottom sides to press and fasten the relay housing and the relay core together, completing the assembly. Since the connection between the relay housing and the relay core requires external pressure to fasten them together, and the relay housing is a shell-shaped structure, it is prone to deformation when subjected to excessive pressure. Therefore, the pressing assembly of this invention adopts a combination of bottom pushing and top pressing assembly method. The lower top block pushes the relay core up, while the upper pressing conformal block presses down on the relay housing to complete the mutual pressing and fastening of the two, effectively reducing the deformation of the relay housing during the pressing process.

Example 7

[0068] As an embodiment of the present invention, the present invention discloses an assembly process for an automatic relay assembly machine, comprising the following process steps:

[0069] S1, Loading and Transfer: The relay cores and relay housings exported from the previous workstation are transported to the transfer loading platform;

[0070] S2, Relay Core Loading: The relay core on the transfer loading platform is moved to a feeding position at the core loading station by the first lifting arm;

[0071] S3, Relay Housing Loading: After the relay core is loaded in step S1, the turntable rotates to the housing loading station, and the relay housing on the transfer loading platform is moved to another loading position by the second lifting arm;

[0072] S4. Gasket Assembly and First Marking: After the relay housing is loaded in step S3, the turntable rotates to the gasket assembly station. The material handling component of the turntable mechanism clamps the relay core and lifts it upward. At the same time, the gaskets exported by the gasket loading component are transported to the material placement position of the relay core by the gasket transfer component in a back-and-forth rotation. At the same time, the first marking gun performs the first marking on the relay housing. Then the material handling component places the relay core on the gasket.

[0073] S5. Core scanning and pre-assembly: After the gasket is assembled and the first marking is completed in step S4, the turntable rotates to the scanning and pre-assembly station. The material picking and scanning mechanism lifts the relay housing upwards, and its barcode scanner scans the relay core. Then, the lifted relay housing is placed on the relay core from above to complete the pre-assembly.

[0074] S6. Pressing and Assembly and Second Marking: After the pre-assembly is completed in step S5, the turntable rotates to the second marking and assembly station. The pressing component of the marking and pressing mechanism pushes the relay core from below and then presses the relay housing from above, so that the connecting buckle of the relay core and the relay housing is fastened and fixed to each other. Then, the second marking gun of the marking and pressing mechanism marks the relay housing for the second time.

[0075] S7. Inspection and unloading: After the pressing assembly and second marking in step S6 are completed, the product is inspected by CCD camera. Good products are transported to the unloading transfer station for buffering, while defective products are transported to the NG platform for buffering.

[0076] Furthermore, the present invention also includes a first marking gun 10, a third lifting arm 14, and a feeding mechanism. The first marking gun 10 is located outside the gasket assembly station C so as to perform the first marking on the relay housing during gasket assembly. The feeding mechanism includes a feeding transfer table 6 and an NG platform 15 arranged in a straight line on the side of the turntable 71. The feeding transfer table 6 and the NG platform 15 are respectively provided with strip-shaped storage slots, which are connected to each other. A feeding component is provided at the connection between the two storage slots. The feeding component is driven by a cylinder to move a paddle extending above the storage slot back and forth in a straight line so as to push the tested relay into the feeding transfer table 6 or the NG platform 15. The third lifting arm 14 is mounted between the feeding mechanism and the turntable 71 and is used to transport the assembled relay into the feeding mechanism.

[0077] It should be noted that each assembly station on the turntable 71 of the present invention adopts a dual feeding position setting, that is, it includes two feeding positions arranged side by side, so that the relay core 01 and the relay housing 02 can be placed separately before assembly. However, during the marking process, the relay core 01 and the relay housing 02 placed side by side will block the marking path. To solve this problem, the present invention sets the first marking process of the relay housing 02 during the assembly of the gasket. Since the gasket needs to be assembled to the lower part of the relay core, the feeding component of the turntable mechanism 7 lifts the relay core 02 upward to place the gasket 04. At the same time, after being lifted upward, The relay core 02 provides space for the first marking gun 10 to mark the relay housing 02. In addition, the relay core 01 needs to be scanned before assembly for information traceability. Due to the same problem, the relay housing 02 will block the scanning path. Therefore, this invention combines the pre-assembly and scanning processes. At the scanning pre-assembly station D, the relay housing 02 is first lifted upward by the material picking and scanning mechanism 11, and then scanned by the barcode scanner 118. After scanning, the lifted relay housing 02 is placed on the relay core 01 from above, thereby completing the relay pre-assembly while avoiding scanning interference.

[0078] Furthermore, this invention designs an automatic relay assembly machine and its assembly process that combines parallel dual feeding positions with multiple assembly stations to achieve automatic independent feeding of relay cores and housings, marking and gasket installation, barcode scanning pre-assembly, secondary marking, and pressing assembly, effectively improving assembly efficiency. This invention aims to provide a downstream process for relay manufacturing, belonging to the category of automated relay assembly equipment. Its function is to achieve automated assembly of relay cores, relay housings, and gaskets. Simultaneously, during the assembly process, it completes two markings on the relay housing and automatic barcode scanning of the relay core, and realizes post-assembly inspection, sorting, and unloading.Specifically, this invention uses a machine as the supporting structure, and the machine is equipped with a turntable mechanism. The turntable of the turntable mechanism serves as a rotating platform, and along the circumferential direction, it is provided with a core loading station, a housing loading station, a gasket assembly station, a barcode scanning pre-assembly station, and a second marking and assembly station. It should be noted that each of the above stations is provided with two material placement positions at intervals to allow for the side-by-side placement of relay cores and relay housings before assembly. A transfer loading platform is provided on the side of the core loading station and the housing loading station. A first lifting arm and a second lifting arm are mounted on the side of the transfer loading platform. After the relay cores and relay housings exported from the previous station are transferred to the transfer loading platform by the robot arm, they are respectively processed by the first... The first and second lifting arms move the relay cores from the core loading station and the housing loading station to the unloading position. Then, the relay cores are rotated to the gasket assembly station via a turntable. At the gasket assembly station, automatic gasket assembly is achieved. During assembly, the process of lifting the relay core using the material handling component to place the gasket effectively solves the problem of interference between the relay core and the first marking of the relay housing. This also solves the problem of interference with the relay housing marking caused by parallel placement. Simultaneously, after the gaskets are automatically exported by the gasket loading component, a gasket transfer component located between the gasket loading component and the turntable achieves cyclical picking and unloading through reciprocating rotation, effectively improving the gasket... To improve assembly efficiency, after the gasket and initial marking are completed, the turntable rotates to the barcode scanning pre-assembly station. At this station, the relay core needs to be scanned, but the parallel-placed relay housings would obstruct the scanning path. Therefore, the pre-assembly and scanning actions are combined. First, the relay housing is lifted upwards before scanning the relay core. The lifted relay housing avoids obstructing the scanning. After scanning, the relay housing is then placed onto the relay core from above, completing the pre-assembly and effectively improving assembly efficiency. After pre-assembly, the turntable rotates to the second marking and assembly station, where the second marking gun performs a second marking on the relay housing. It should be noted that... Because the marking information is different, the marking needs to be done on the relay housing twice. At the same time, the pressing assembly outputs power from the top and bottom sides to press and fasten the relay housing and the relay core together, completing the assembly. Since the connection between the relay housing and the relay core requires external pressure to fasten them together, and the relay housing is a shell-shaped structure, it is prone to deformation when subjected to excessive pressure. Therefore, the pressing assembly of this invention adopts a combination of bottom pushing and top pressing assembly method. The lower top block pushes the relay core up, while the upper pressing conformal block presses down on the relay housing to complete the mutual pressing and fastening of the two, effectively reducing the deformation of the relay housing during the pressing process.

[0079] The embodiments of this invention are merely illustrative of specific implementation methods and are not intended to limit the scope of protection. Those skilled in the art can make modifications based on these embodiments; therefore, all equivalent changes or modifications made in accordance with the scope of this invention's patent claims fall within the scope of this invention's patent claims.
