[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a fixture and workbench for SMT assembly, including a workbench body 1, a fixture body 2 mounted on the surface of the workbench body 1, a power socket 3 mounted on the surface of the workbench body 1, and an auxiliary device 4 on the surface of the workbench body 1 to achieve the effect of clamping fixture bodies 2 of different sizes, avoiding the situation where the component is deformed and the soldering deviation is caused by external impact or vibration during the production process, resulting in a low component yield, thus improving the practicality of the device. The surface of the workbench body 1 is provided with a protective device 5 to achieve the effect of protecting the power socket 3, preventing waste generated during production and small debris from falling into the power socket 3, which could cause the power socket 3 to become blocked or damaged, thus making the workbench body 1 unusable, thus improving the practicality of the device.
[0029] The specific setup and function of its auxiliary device 4 and protective device 5 will be explained below.
[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the auxiliary device 4 includes two support rods 401, which are fixedly connected to the surface of the workbench body 1. Support plates 402 are fixedly connected to the ends of the two support rods 401 that are far apart from each other. A push rod 403 is slidably inserted into the support plate 402. A clamping plate 404 is fixedly connected to one end of the push rod 403. A screw rod 406 is fixedly connected to one side of the support plate 402. A push plate 408 is slidably connected to the arc surface of the screw rod 406. A limiting rod 409 is slidably inserted into the push plate 408. A circular plate 411 is fixedly connected to one end of the limiting rod 409. Several openings are formed on the surface of the push rod 403. A limiting hole is made, and a flexible plate 405 is fixedly connected to the surface of the clamping plate 404. The size of the limiting rod 409 is adapted to the size of the limiting hole on the surface of the push rod 403. Pushing the push rod 403 causes it to slide within the support plate 402, which in turn drives the clamping plate 404. The clamping plate 404 then drives the flexible plate 405 until the flexible plate 405 adheres to the fixture body 2. This reduces the friction between the clamping plate 404 and the fixture body 2, preventing wear and deformation of the fixture body 2 due to over-clamping. A spring 410 is fitted onto the arc surface of the limiting rod 409, and the two ends of the spring 410 are respectively connected to the circular plate 411 and the push plate. When the circular plate 411 is loosened, the spring 410's rebound force causes the limiting rod 409 to slide within the push plate 408 until it inserts into the limiting hole on the surface of the push rod 403. This achieves a stable connection between the limiting rod 409 and the push rod 403, preventing shaking during production and thus improving the stability of the device. The arc surface of the screw rod 406 is rotatably connected to a rotating ring 407, whose surface is fixedly connected to the push plate 408. The support plate 402 has a retraction hole on its surface. Rotating the rotating ring 407 causes the push plate to move. 408 rotates on the arc surface of the screw rod 406, the push plate 408 drives the limit rod 409, the limit rod 409 drives the circular plate 411 until the limit rod 409 is perpendicular to the recycling hole on the surface of the support plate 402, and then pushes the limit rod 409 to slide inside the push plate 408 until the limit rod 409 is inserted into the recycling hole on the surface of the support plate 402, thus achieving the effect of rotating and recycling the limit rod 409. This avoids the situation where the limit rod 409 slides back and forth inside the push plate 408 due to the shaking caused during production when the operator adjusts the fixture body 2 of different sizes, thus requiring the operator to keep pulling the limit rod 409.
[0031] Reference Figure 4 and Figure 5As shown, specifically, the protective device 5 includes a support frame 501, which is fixedly connected to the surface of the workbench body 1. Connecting plates 502 are fixedly connected to both ends of the support frame 501. A rotating rod 503 is fixedly connected to one side of the two connecting plates 502 that are close to each other. A protective cover 505 is rotatably connected to the arc surface of the rotating rod 503. A fixing block 506 is fixedly connected to the surface of the workbench body 1. A short rod 507 is fixedly connected to one side of the fixing block 506. A strip plate 508 is rotatably connected to the arc surface of the short rod 507. A fixing rod 509 is slidably inserted into the strip plate 508. A fixing hole is opened on the surface of the protective cover 505. A baffle 510 is fixedly connected to the arc surface of the fixing rod 509. The size of the fixing rod 509 matches the size of the fixing hole on the surface of the protective cover 505. Pulling the fixing rod 509 causes it to move in the strip plate 505. The strip plate 508 slides within the strip plate 508, and the fixing rod 509 drives the baffle 510 until the baffle 510 abuts against the strip plate 508, thus blocking the fixing rod 509 and preventing it from slipping out of the strip plate 508 due to shaking caused by external factors, which would damage the fixing rod 509 and make it unusable. The arc surface of the rotating rod 503 is fitted with two torsion springs 504, and the two ends of the torsion springs 504 are fixedly connected to the connecting plate 502 and the protective cover 505, respectively. When the fixing of the protective cover 505 is released, the torque of the torsion springs 504 drives the protective cover 505 to rotate on the arc surface of the rotating rod 503 until the protective cover 505 is fully opened, achieving the effect of automatic opening of the protective cover 505. This reduces the number of operation steps for the operator, increases the work efficiency of the operator, and improves the convenience of the device.
[0032] Working principle: The limiting rod 409 is pulled out from the limiting hole on the surface of the push rod 403. The rotating ring 407 is rotated, which drives the push plate 408 to rotate on the arc surface of the screw rod 406. The push plate 408 drives the limiting rod 409, which in turn drives the circular plate 411 until the limiting rod 409 is perpendicular to the recycling hole on the surface of the support plate 402. Then, the limiting rod 409 is pushed to slide within the push plate 408 until it is inserted into the recycling hole on the surface of the support plate 402. The push rod 403 is then pushed, and it slides within the support plate 402, driving the clamping plate 404. The clamping plate 404 drives the flexible plate 405 until the flexible plate 405 adheres to the fixture body 2. The limiting rod 409 is then pulled out from the support plate 403. Pull out the jig body 2 from the recycling hole on the surface, rotate the rotating ring 407, the rotating ring 407 drives the push plate 408 to rotate on the arc surface of the screw rod 406, the push plate 408 drives the limiting rod 409, the limiting rod 409 drives the circular plate 411 until the limiting rod 409 is perpendicular to the limiting hole on the surface of the push rod 403, release the circular plate 411, the rebound force of the spring 410 drives the limiting rod 409 to slide in the push plate 408 until the limiting rod 409 is inserted into the limiting hole on the surface of the push rod 403, thus achieving the effect of clamping the jig body 2 of different sizes, avoiding the situation where the component is deformed and the welding deviation is caused by external force impact or vibration during the production process, resulting in a low component yield, and improving the practicality of the device.
[0033] By pulling the fixing rod 509, the fixing rod 509 slides within the strip plate 508. The fixing rod 509 drives the baffle 510 until the baffle 510 abuts against the strip plate 508, pushing the protective cover 505 to rotate on the arc surface of the rotating rod 503 until the protective cover 505 fits against the surface of the power socket 3. Then, the strip plate 508 is rotated, and the strip plate 508 rotates on the arc surface of the short rod 507. The strip plate 508 drives the fixing rod 509 until the fixing rod 509 is perpendicular to the fixing hole on the surface of the protective cover 505. Then, the fixing rod 509 is pushed to slide within the strip plate 508. The device moves until the fixing rod 509 is inserted into the fixing hole on the surface of the protective cover 505. When the operator needs to use it, the fixing of the protective cover 505 is released, and the torque of the torsion spring 504 drives the protective cover 505 to rotate on the arc surface of the rotating rod 503 until the protective cover 505 is fully opened. This achieves the effect of protecting the power socket 3, preventing waste generated during production and small debris from falling into the power socket 3, which could cause the power socket 3 to become blocked or damaged, thus making it difficult to continue using the workbench body 1. This improves the practicality of the device.
