Description

Technical Field

[0001] The invention belongs to the technical field of relay production, and in particular relates to a tinning and testing device for relay terminals. Background Art

[0002] After the relay winding is completed, the relay terminals need to be tinned and the relay resistance value needs to be tested. The tinning of the relay terminals is usually done manually, which is inefficient and requires high proficiency of the operators. It requires a large number of technicians, and when the personnel are tired, a large number of unqualified products are easily produced.

[0003] The existing automated equipment for tinning and testing relay terminals mostly uses a graduated circular turntable. Although it solves the problem of manual tinning, the slots of the graduated circular turntable can only fix, tin and test the terminals of a single relay. The more relay fixing slots there are on the edge of the graduated circular turntable, the larger the diameter of the graduated circular turntable will be and the lower the surface utilization rate will be. In addition, considering the space occupied by other related equipment, the graduated circular turntable is usually made smaller, so the tinning and testing of relay terminals are still inefficient. Summary of the invention

[0008] Furthermore, the loading assembly includes a loading telescopic rod and a fixed plate clamp, the loading telescopic rod is arranged on both sides of the frame, the front end of the loading telescopic rod is provided with a clamp positioning boss, the center of the clamp positioning boss is provided with a clamp slide rod hole, the side wall of the clamp positioning boss is provided with a loading cylinder, the fixed plate clamp is arranged on the loading cylinder, a positioning column is provided on the inner side of the fixed plate clamp, a clamp slide rod is provided at the bottom of the fixed plate clamp, the positioning column slot is provided in the positioning column, and the clamp slide rod slides in the clamp slide rod hole.

[0009] Preferably, the movement of the fixing plate clamp is controlled by the feeding telescopic rod, so that the positioning column is engaged in the positioning column slot of the relay fixing device, and the relay fixing device is transported from the feeding conveyor to the front side of the test frame. During the retraction of the feeding telescopic rod, the fixing column will be inserted into the relay in the relay fixing device. As the feeding cylinder drives the fixing plate clamp to descend, the relay is completely detached from the relay fixing device, so that the relay is fixed on the fixing column, thereby achieving the technical effect of automatic feeding of the test frame by the feeding assembly, and during the descent of the fixing plate clamp, the relay fixing device will be blocked by the recovery plate, so that the positioning column is detached from the positioning column slot, that is, the relay fixing device is detached from the fixing plate clamp and slides from the recovery plate, thereby achieving the technical effect of recovering the relay fixing device.

[0012] Furthermore, the test frame is arrayed with fixed columns, the front end of the fixed columns is provided with a penetrating limit hole, both ends of the limit hole are provided with limit keys, limit key springs are provided between the limit keys, both ends of the test frame are provided with transmission wheels, the lifting frame is provided with a rotating motor, and the rotating motor and the transmission wheel are connected by a transmission belt.

[0013] Preferably, the limit key applies a clamping force to the side of the relay to prevent the relay from falling from the fixed column, and prevents the relay from rotating to cause the terminal to shift, affecting the subsequent detection of the terminal. At the same time, the driving motor drives the sliding frame to move on the frame, and the sliding arm cylinder drives the lifting frame to rise and fall. At the same time, the rotating motor drives the test frame to rotate, thereby driving the relay to complete multiple processes such as soldering, tinning and detection of its terminals.

[0014] Furthermore, the soldering assembly includes a heating device and a lifting plate, the heating device is provided with a heating column fixing plate, a heating column is arrayed on one side of the heating column fixing plate, a heating cross bar is provided at the bottom of the heating column, a soldering groove is provided at the end of the heating cross bar, the soldering groove is provided in the soldering pool, the lifting plate is provided at the bottom of the heating column fixing plate, a soldering cylinder is provided at the bottom of the lifting plate, the soldering cylinder is provided in the cylinder groove, and the soldering cylinder is provided on the cylinder seat.

Gas rod connecting columns are provided on both sides of the tin scraper plate. The tin plate gas rod is arranged in the gas rod groove, and the tin plate gas rod is connected to the gas rod connecting column.

[0016] Preferably, the liquid tin in the soldering pool is heated by heating columns and heating cross bars. When the test frame moves to the soldering trough position, the soldering cylinder first drives the heating device to move upward, and then the soldering trough filled with liquid tin rises, and then the tin plate gas rod will pull back and scrape the tin plate to scrape the oxide on the surface of the liquid tin into the waste tin collection tank, and then the test frame descends to complete the tinning of the relay terminals.

[0017] Furthermore, the unloading assembly includes a unloading device and a unloading cylinder, the unloading device is arranged on the upper rear side of the frame, the unloading cylinder linear array is arranged in the unloading cylinder groove, the unloading device upper linear array is provided with a unloading trough, the back plate of the unloading trough is provided with a limit opening, the bottom of the unloading trough is provided with a rotating plate, and the cylinder shaft end of the unloading cylinder is arranged on the back of the rotating plate.

[0019] Preferably, the test columns of the test row correspond one by one to the terminals of the relay on the test frame, and the tinned relay terminals are inspected. After the inspection is completed, the test row rotates to a horizontal state, moves above the unloading device and descends to the limit port, and the relay is in the unloading chute. The test row pulls back, and the relay falls off from the fixed column under the obstruction of the limit port and slides into the unloading conveyor belt. If the relay is unqualified, the unloading cylinder under the unloading chute corresponding to the unqualified relay will start, driving the rotating plate of the corresponding unqualified chute to rotate, so that the relay falls from the unloading device in advance, and the unqualified products are collected by the waste conveyor belt.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows: 1. There are ten relay slots on the relay fixture. The relays to be welded are placed in the relay slots. The relay fixture carrying multiple relays is transported to the front side of the rack by the feeding conveyor belt, waiting for the relay terminals to be tinned and tested. This solves the problem that the indexing circle turntable can only tin and test a single relay, greatly improving the production efficiency of the relay.

[0021] 2. Control the movement of the fixing plate fixture by the feeding telescopic rod, so that the positioning column is engaged in the positioning column slot of the relay fixture, and the relay fixture is transported from the feeding conveyor to the front side of the test frame. During the retraction of the feeding telescopic rod, the fixing column will be inserted into the relay in the relay fixture. As the feeding cylinder drives the fixing plate fixture to descend, the relay is completely detached from the relay fixture, so that the relay is fixed on the fixing column, thereby achieving the technical effect of automatic feeding of the test frame by the feeding component, and during the descent of the fixing plate fixture, the relay fixture will be blocked by the recovery plate, so that the positioning column is detached from the positioning column slot, that is, the relay fixture is detached from the fixing plate fixture and slides off the recovery plate, thereby achieving the technical effect of recovering the relay fixture.

[0022] 3. The limit key will apply clamping force to the side of the relay to prevent the relay from falling from the fixed column, and prevent the relay from rotating and causing the terminal to shift, affecting the subsequent detection of the terminal. At the same time, the driving motor drives the sliding frame to move on the frame, and the sliding arm cylinder drives the lifting frame to rise and fall. At the same time, the rotating motor drives the test frame to rotate, thereby driving the relay to complete multiple processes such as soldering, tinning and detection of its terminals.

[0023] 4. The liquid tin in the soldering pool is heated by the heating column and the heating crossbar. When the test frame moves to the soldering tank position, the soldering cylinder first drives the heating device to move upward, and then the soldering tank filled with liquid tin rises. Then the tin plate gas rod will pull back the tin plate to scrape the oxide on the surface of the liquid tin into the waste tin collection tank. After that, the test frame descends to complete the tinning of the relay terminals.

[0024] 5. The test columns of the test row correspond to the terminals of the relay on the test stand one by one, and the tinned relay terminals are tested. After the test is completed, the test row rotates to a horizontal state, moves to the top of the unloading device and descends to the limit port. The relay is in the unloading chute, and the test row pulls back. The relay falls off from the fixed column under the blockage of the limit port and slides into the unloading conveyor belt. If the relay is unqualified, the unloading cylinder under the unloading chute corresponding to the unqualified relay will start, driving the rotating plate of the corresponding unqualified chute to rotate, so that the relay falls from the unloading device in advance, and the unqualified products are collected by the waste conveyor belt.

[0038] The unloading assembly 6 includes a unloading device 61 and a unloading cylinder 62. The unloading device 61 is arranged on the upper rear side of the frame 2. The unloading cylinder 62 is arranged in a linear array in the unloading cylinder groove 26. The unloading device 61 is provided with an unloading trough 611 in a linear array. A limiting opening 613 is provided on the back plate of the unloading trough 611. A rotating plate 612 is provided at the bottom of the unloading trough 611. The end of the cylinder shaft of the unloading cylinder 62 is provided on the back of the rotating plate 612.

[0039] The unloading assembly 6 further includes an unloading conveyor belt 63 and a waste conveyor belt 64 . The unloading conveyor belt 63 is located at the end of the unloading trough 611 , and the waste conveyor belt 64 is located below the rotating plate 612 .

[0040] When in use, the relay fixture 12 equipped with the relay 7 to be welded is placed on the feeding conveyor 111, and the feeding conveyor 111 brings the relay fixture 12 to the front baffle. At this time, the fixing plate fixture 32 is located directly below the relay fixture 12, and the positioning column 321 is directly opposite to the positioning column slot 122. The loading cylinder 312 is started, driving the fixing plate fixture 32 to move up, and the positioning column 321 is engaged in the positioning column slot 122, and driving the relay fixture 12 to disengage from the feeding conveyor 111. At this time, the sliding frame 4 is located at the front side of the frame 2. At the same time, under the adjustment of the rotating motor 421, the test frame 43 is in a horizontal state, and the bottom of the fixing column 431 faces forward and directly faces the relay 7 on the relay fixture 12. The center hole of the relay 7 is formed, the feeding telescopic rod 31 is retracted, and the fixing column 431 is embedded in the center hole of the relay 7. Then the feeding cylinder 312 drives the fixing plate fixture 32 to descend, and the relay 7 is completely separated from the relay fixing device 12, so that the relay 7 is fixed on the fixing column 431. In the process of the fixing plate fixture 32 descending, the relay fixing device 12 will be blocked by the recovery plate 112, so that the positioning column 321 is separated from the positioning column slot 122, that is, the relay fixing device 12 is separated from the fixing plate fixture 32, and the recovery plate 112 completes the recovery of the relay fixing device 12. Then the feeding telescopic rod 31 is extended, and the fixing plate fixture 32 is brought to the right below the new relay fixing device 12 on the feeding conveyor belt 111, and waits for the next group of relays 7 to be detected.

[0041] After the fixed column 431 is loaded with the relay 7, the driving motor 412 is started, driving the roller 414 to rotate, so that the sliding support arm 41 slowly moves toward the rear side of the frame 2, and at the same time, the rotating motor 421 drives the test frame 43 to rotate downward until the fixed column 431 is in a vertical downward state, wherein the limit key 432 on the fixed column 431 will apply a clamping force to the side of the relay 7 to prevent the relay 7 from falling from the fixed column 431. When the test frame 43 moves to the flux groove 21, the sliding support arm 41 stops moving, the sliding arm cylinder 44 drives the lifting frame 42 to move downward, and the test frame 43 follows the lifting frame 42 to move downward. The terminals of the relay 7 will be immersed in the flux. After the terminal surface is covered with flux, the sliding arm cylinder 44 drives the lifting frame 42 to move up, and the test frame 43 follows the lifting frame 42. The test frame 42 moves up, the relay 7 is separated from the flux tank 21, and the sliding support arm 41 continues to move toward the solder pool 23. When the test frame 43 moves to above the solder tank 514, the sliding support arm 41 stops moving. First, the soldering cylinder 521 drives the heating device 51 to move up, and then the solder tank 514 filled with liquid tin rises. The initial position of the tin scraper 53 is on the upper front side of the solder tank 514, and then the tin plate gas rod 54 will pull back the tin scraper 53 to scrape the oxide on the surface of the liquid tin into the waste tin collection tank 231. Then the test frame 43 descends. After the tinning of the relay 7 terminals is completed, the test frame 43 moves up to its original position, and the soldering cylinder 521 drives the lifting plate 52 to descend, and then the heating column fixing plate 511 descends. At the same time, the tin plate gas rod 54 extends to reset the tin scraper 53.

[0042] The sliding support arm 41 drives the test frame 43 to continue to move toward the test row 24. When the test frame 43 moves to the top of the test row 24, the sliding support arm 41 stops moving. At this time, the test columns of the test row 24 correspond one by one to the terminals of the relay 7 on the test frame 43. The test frame 43 moves down to make the terminals contact the test columns to complete the detection of the relay. After the detection is completed, the test row 24 moves up and rotates to a horizontal state so that the bottom of the fixed column 431 faces the rear, and the sliding support arm 41 moves to the rear side of the rack 2. At this time, the relay on the fixed column 431 is above the feed chute 611, and the test frame 43 descends to the limit opening 613. The relay 7 is in the feed chute In 611, the test row 24 is pulled back, and the relay 7 falls off from the fixed column 431 under the obstruction of the limit opening 613, and slides into the unloading conveyor belt 63. If the relay 7 is unqualified, the unloading cylinder 62 under the unloading trough 611 corresponding to the unqualified relay will be started, driving the rotating plate 612 of the corresponding unqualified trough 611 to rotate, so that the relay falls from the unloading device 61 in advance, and the unqualified products are collected by the waste conveyor belt 64. Then the sliding frame 4 will move to the front side of the frame 2, and the rotating motor 421 will drive the test frame 43 to rotate, so that the bottom of the fixed column 431 faces forward, and the next group of relays are tested. The above is the overall workflow of the present invention.
