Description

Technical Field

[0001] The present invention relates to the field of relay automatic assembly, and in particular to a relay automatic testing machine and a testing process thereof. Background Art

[0002] A relay is an electrical control device. It is an electrical device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity reaches the specified requirements. 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 usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current; it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] The structure of the relay includes components such as a relay housing, an iron frame, a magnetic block and a core body. The relay housing is a rectangular box-shaped structure, the middle of which is a cavity with an opening at the top for installing other components. The relay iron frame is a U-shaped frame structure. Two relay iron frames need to be assembled in a single relay. After the two iron frames are symmetrically assembled to form a rectangular frame structure, it is also necessary to vertically insert assembly magnetic blocks at both ends of the rectangular frame structure formed by the iron frames; then, the relay core body is vertically inserted into the rectangular frame with the magnetic blocks installed to form a semi-finished relay; finally, the semi-finished relay is assembled as a whole into the relay housing, and the core body and the iron frame are riveted and fixed to form a semi-finished relay; in the above assembly process, it is necessary to introduce the semi-finished relay into the test circuit to test its parameters before assembling the semi-finished relay into the relay housing to avoid repeated disassembly and assembly due to poor testing. Based on the above process requirements, a relay automatic testing machine needs to be designed in the relay automatic assembly line. The automatic testing machine needs to automatically connect with the automatic assembly machines in the front and rear sections of the relay automatic assembly line, and realize automatic testing of relay semi-finished products to improve the production capacity and quality of relay assembly and testing.

[0017] The beneficial effects of the present invention are: In view of the defects and shortcomings of the prior art, the present invention independently develops and designs a relay automatic testing machine and a testing process thereof which adopts dual-channel synchronous feeding and dual-position buffer transfer testing to effectively improve the relay testing efficiency, and adopts flexible stripping and transfer to realize transfer buffering of multiple groups of relays, thereby improving the transfer efficiency while reducing the equipment cost during the relay assembly test.

[0018] The present invention aims to provide an automatic testing process for a relay semi-finished product composed of a relay iron frame, a magnetic block and a core body before it is assembled into a shell. The present invention is located between a relay semi-finished product assembly machine and a relay finished product assembly machine in an automatic assembly production line of a relay, and is automatically connected with the two assembly machines; the present invention solves the problem of automatic testing before and after the assembly of the relay semi-finished product, realizes dual-channel feeding and dual-buffer material distribution testing, ensures the continuity of test feeding, realizes automatic caching of unloading, realizes the continuity of unloading, and completes the automatic and efficient connection with the front and rear two-stage assembly machines, so as to maximize the assembly and testing capacity. Specifically, the present invention as a whole comprises a dual-channel feeding mechanism, a first buffer mechanism, a second buffer mechanism, a testing mechanism, a test material selection mechanism, a buffer material selection mechanism, a first pushing mechanism, a second pushing mechanism and a feeding mechanism; the overall layout of the present invention is to respectively arrange the dual-channel feeding mechanism and the feeding mechanism on the corresponding two sides of the machine along the X direction to respectively connect the assembly machines of the front and rear sections, and the two straight transmission channels of the dual-channel feeding mechanism respectively and synchronously and independently transport the product components forward, and there is a height difference in the extension length of the end thereof; a testing station is arranged at the end of the dual-channel feeding mechanism, a testing mechanism is arranged above the testing station, and a first buffer mechanism and a second buffer mechanism are respectively arranged on both sides of the testing station in parallel and at intervals, and the first buffer mechanism and the second buffer mechanism extend along the Y direction; in addition, a test material selection mechanism is arranged below the testing station, the first buffer mechanism and the second buffer mechanism along the X direction, and a buffer material selection mechanism is arranged below the second buffer mechanism. The two linear transmission channels synchronously transmit product components forward linearly. The product components in one of the linear transmission channels are pushed into the first buffer mechanism along the Y direction by the first pushing mechanism, and then pushed to the test station along the X direction by the test material dialing mechanism for testing, or cached in the first buffer mechanism for waiting for testing; after the product components in the other linear transmission channel are transmitted to the second buffer mechanism, they are pushed toward the test station along the Y direction by the cache material dialing mechanism, and then pushed into the test station for testing by the test material dialing mechanism, or cached in the second buffer mechanism for waiting for material; thereby realizing dual-channel feeding and dual-buffer waiting material supply and testing, which can ensure the material testing and maintenance at the test station Maintain continuous stability, reduce downtime waiting time, and ensure the stability of test capacity efficiency; after the product component is tested at the test station, it is pushed to the second cache mechanism in the opposite direction along the X direction by the test material transfer mechanism, and then pushed in the opposite direction along the Y direction toward the transfer mechanism set at the end of the second cache mechanism by the second material pusher mechanism. At this time, the second cache mechanism is used as a cache platform after the inspection is completed, and the second moving arm erected above the second cache mechanism is used to transport the defective products that are NG in the test to the NG cache mechanism for caching. After the qualified products are transported to the transfer mechanism by the first moving arm for transfer caching, they are then transmitted to the qualified product unloading mechanism through the transfer mechanism to realize unloading output.Furthermore, the present invention uses the carrier of the product component as a bearing mechanism to simultaneously realize the bearing of multiple relays during the automatic loading, caching, testing and transfer unloading processes, thereby improving the testing efficiency. In addition, during the pushing and caching before the test and the unloading and caching after the test, the test material transfer mechanism and the cache material transfer mechanism arranged below are utilized to realize the transfer of the product component. This structural design can effectively save installation space while completing the automatic transfer of the product component.

[0019] Furthermore, the test material-dipping mechanism and the cache material-dipping mechanism transfer materials back and forth after passing through the upper strip chute upwards. In the actual working process, after pushing one group of product components, it is necessary to return in a straight line to push the next group of product components. The technical problem existing in its straight line return process is that it generates motion interference with the product components placed above the strip chute. To solve this technical problem, the test material-dipping mechanism of the present invention controls the first dipping block to move up and down in the vertical direction through the lifting cylinder. When it needs to push a product component, the lifting cylinder drives the first dipping block to pass through the strip chute upwards. When it completes pushing a group of product components and needs to return, the lifting cylinder drives the first dipping block to retract downwards, thereby avoiding The invention also solves the problem of motion interference in the buffer material mechanism of the present invention. As another technical means, the second shift block of the buffer material mechanism of the present invention adopts a rotatable setting mode, one end of which is rotatably connected to the rotating shaft, and the other end is provided with an upward elastic force by a vertically connected spring below to maintain the state of pushing the second shift block upward, so that the vertical end wall of the other end of the second shift block can push the product assembly horizontally and then move it. When the second shift block completes a single push and returns, the inclined guide surface set on the top of the other end of the second shift block gradually contacts the bottom surface of the product assembly. During the return process, the bottom surface of the product assembly compresses the second shift block downward, so that the spring is compressed downward, thereby solving the problem of motion interference with the product assembly during the return process.

[0020] Furthermore, the function of the first lifting arm and the second lifting arm of the present invention during the working process is to transfer the relay between different mechanisms. The first lifting arm and the second lifting arm use a material picking head as an execution structure. The material picking head drives the two groups of clamps to move closer to or away from each other through a material picking cylinder to achieve clamping and fixing of the relay. The special feature is that the material picking head uses a downwardly extending pre-pressing frame as a supporting structure, and a pre-pressing plate is provided at the bottom of the pre-pressing frame, and the pre-pressing plate is located between the two groups of clamps. During the material picking process, when the material picking head as a whole moves downward toward the relay, the two groups of clamps are in an open state, and the pre-pressing plate contacts the relay downward and presses the relay horizontally downward to achieve pre-pressing of the relay before picking, effectively ensuring the flatness of the relay and improving the position accuracy during material picking.

The product components in one of the linear transmission channels are pushed into the first buffer mechanism along the Y direction by the first pushing mechanism, and then pushed to the test station along the X direction by the test material dialing mechanism for testing, or cached in the first buffer mechanism for waiting for testing; after the product components in the other linear transmission channel are transmitted to the second buffer mechanism, they are pushed toward the test station along the Y direction by the cache material dialing mechanism, and then pushed into the test station for testing by the test material dialing mechanism, or cached in the second buffer mechanism for waiting for material; thereby realizing dual-channel feeding and dual-buffer waiting material supply and testing, which can ensure the material testing and maintenance at the test station Maintain continuous stability, reduce downtime waiting time, and ensure the stability of test capacity efficiency; after the product component is tested at the test station, it is pushed to the second cache mechanism in the opposite direction along the X direction by the test material transfer mechanism, and then pushed in the opposite direction along the Y direction toward the transfer mechanism set at the end of the second cache mechanism by the second material pusher mechanism. At this time, the second cache mechanism is used as a cache platform after the inspection is completed, and the second moving arm erected above the second cache mechanism is used to transport the defective products that are NG in the test to the NG cache mechanism for caching. After the qualified products are transported to the transfer mechanism by the first moving arm for transfer caching, they are then transmitted to the qualified product unloading mechanism through the transfer mechanism to realize unloading output.Furthermore, the present invention uses the carrier of the product component as a bearing mechanism to simultaneously realize the bearing of multiple relays during the automatic loading, caching, testing and transfer unloading processes, thereby improving the testing efficiency. In addition, during the pushing and caching before the test and the unloading and caching after the test, the test material transfer mechanism and the cache material transfer mechanism arranged below are utilized to realize the transfer of the product component. This structural design can effectively save installation space while completing the automatic transfer of the product component.

[0052] Furthermore, the test material-dipping mechanism and the cache material-dipping mechanism transfer materials back and forth after passing through the upper strip chute upwards. In the actual working process, after pushing one group of product components, it is necessary to return in a straight line to push the next group of product components. The technical problem existing in its straight line return process is that it generates motion interference with the product components placed above the strip chute. To solve this technical problem, the test material-dipping mechanism of the present invention controls the first dipping block to move up and down in the vertical direction through the lifting cylinder. When it needs to push a product component, the lifting cylinder drives the first dipping block to pass through the strip chute upwards. When it completes pushing a group of product components and needs to return, the lifting cylinder drives the first dipping block to retract downwards, thereby avoiding The invention also solves the problem of motion interference in the buffer material mechanism of the present invention. As another technical means, the second shift block of the buffer material mechanism of the present invention adopts a rotatable setting mode, one end of which is rotatably connected to the rotating shaft, and the other end is provided with an upward elastic force by a vertically connected spring below to maintain the state of pushing the second shift block upward, so that the vertical end wall of the other end of the second shift block can push the product assembly horizontally and then move it. When the second shift block completes a single push and returns, the inclined guide surface set on the top of the other end of the second shift block gradually contacts the bottom surface of the product assembly. During the return process, the bottom surface of the product assembly compresses the second shift block downward, so that the spring is compressed downward, thereby solving the problem of motion interference with the product assembly during the return process.
