[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-5As shown, this utility model is a SMT (Surface Mount Technology) calibration mechanism, including a base plate 1, and further comprising: a fixing plate 101 bolted to one side of the upper surface of the base plate 1; symmetrically formed first sliding grooves 102 on the upper surface of the base plate 1; a placement platform 2 disposed above the base plate 1, and the placement platform 2 connected to the base plate 1 via support legs; a support plate 201 fixedly connected to one side of the placement platform 2; a vertical sliding groove 202 formed on the upper surface of the placement platform 2; symmetrically formed horizontal sliding grooves 203 on the upper surface of the placement platform 2; and a limiting block 3 connected to one side of the upper surface of the placement platform 2. The two sides of the fixing plate 101 are fixedly connected to the base plate 1 by bolts. A rectangular groove is opened in the center of the fixing plate 101, and one end of the first connecting rod 301 passes through the rectangular groove and is fixedly installed on the side of the fixing plate 101 by bolts, thereby fixing the position of the first connecting rod 301. The limiting block 3 is fixedly installed on the upper surface of the placement platform 2. The sum of the lengths of the two sets of horizontal sliding grooves 203 is less than the side length of the placement platform 2, and the horizontal sliding grooves 203 and the vertical sliding grooves 202 form a "T" shape, so that the limiting block 4 and the limiting plate 5 can clamp and limit the sides of SMT components of different sizes, increasing the practicality of the device.

[0025] A first connecting rod 301 is fixedly connected to one side of the limiting block 3, and the cross-section of the first connecting rod 301 is an "L" shaped structure. One end of the first connecting rod 301 is connected to a connecting block 302, and circular grooves are opened on both sides and the front of the connecting block 302. Electromagnets 303 are embedded in the circular grooves. The left end of the first connecting rod 301 is fixedly installed on the surface of the fixing plate 101. The upper end of the first connecting rod 301 is welded to the side of the limiting block 3. The right end of the first connecting rod 301 is fixedly connected to the side of the connecting block 302. Two sets of circular grooves are opened on the front of the connecting block 302, and two sets of electromagnets 303 are embedded in the circular grooves on both sides. There are a total of four sets of electromagnets 303, which are respectively arranged inside the connecting block 302. The electromagnets 303 are electrically connected to the power supply. By energizing the electromagnets 303, the armature 403 is attracted, so that the two sets of limiting blocks 4 clamp and limit the SMT surface mount.

[0026] A clamping mechanism, disposed on the upper surface of the placement platform 2, is used to clamp and limit SMT components. The clamping mechanism includes a limiting block 4, a second connecting rod 401, a fixing block 402, and an armature 403. The limiting blocks 4 are symmetrically arranged on the upper surface of the placement platform 2. The lower surface of the limiting block 4 is connected to the second connecting rod 401, and the upper end of the second connecting rod 401 is slidably engaged inside the transverse groove 203. The middle end of the side of the second connecting rod 401 is connected to the fixing block 402, and the armature 403 is embedded inside the fixing block 402. The second connecting rod 401... The lower end of the limiting block 4 is slidably engaged inside the first slide groove 102. The lower surface of the limiting block 4 is in contact with the upper surface of the placement platform 2. The second connecting rod 401, which is provided on the lower surface of the limiting block 4, passes through the transverse slide groove 203 and is slidably engaged with the transverse slide groove 203, so that the second connecting rod 401 can move along the transverse slide groove 203 with the limiting block 4. The lower end of the second connecting rod 401 is slidably engaged with the first slide groove 102. At the same time, the first slide groove 102 can also limit the second connecting rod 401, increase the stability of the second connecting rod 401 when it moves, and prevent it from shaking.

[0027] When the electromagnet 303 is energized, it becomes magnetic. Then, the armature 403 inside the fixing block 402 is attracted by the electromagnet 303. The armature 403 is embedded inside the fixing block 402, so that the armature 403 can drive the fixing block 402 and the second connecting rod 401 to move. As the second connecting rod 401 moves, the limiting block 4 can limit both sides of the SMT patch, thereby straightening the tilted SMT patch.

[0028] The vertical slide groove 202 is internally slidably engaged with a limiting plate 5, and the limiting plate 5 has a "T" shaped cross-section. The lower end of the limiting plate 5 is threadedly connected to a lead screw 601. One end of the lead screw 601 is connected to a rotating rod 6, and the other end is rotatably connected to a moving block 602. An armature 403 is embedded in the front of the moving block 602. The "T" shaped structure allows the upper end of the limiting plate 5 to limit one side of the SMT surface mount, while the lower end is threadedly connected to the lead screw 601. One end of the lead screw 601 is rotatably connected to the rotating rod 6, and the lead screw 601 can rotate with the rotating rod 6. The other end of the lead screw 601 is rotatably connected to the moving block 602. When the lead screw 601 rotates, the moving block 602 does not rotate with the lead screw 601. When the electromagnet 303 is energized, the armature 403 on the front of the moving block 602 is attracted by the electromagnet 303, causing the moving block 602 to move to the left and be attracted by the electromagnet 303.

[0029] One end of the rotating rod 6 is connected to a sleeve 7. A slider 603 is symmetrically connected to the surface of the rotating rod 6, and the slider 603 is slidably engaged inside the sleeve 7. A spring 702 is provided inside the sleeve 7, and one end of the spring 702 is connected to the rotating rod 6, while the other end is connected to the inner wall of the sleeve 7. A groove is provided inside the sleeve 7, and the slider 603 is slidably engaged inside the groove. The rotating rod 6 can move left and right along the sleeve 7. A hydraulic rod is provided inside the spring 702, one end of which is connected to the rotating rod 6, and the other end is connected to the inner wall of the sleeve 7. The hydraulic rod can prevent the spring 702 from bending or deforming due to excessive force.

[0030] The sleeve 7 has a pulley 701 on its surface, and a transmission belt is connected inside the pulley 701. The lower end of the transmission belt is connected to a rotating shaft 801, and a pulley 701 is also provided at one end of the rotating shaft 801. One end of the rotating shaft 801 is connected to a motor 8, and the rotating shaft 801 is connected to the output end of the motor 8. The pulley 701 on the surface of the sleeve 7 and the pulley 701 on the surface of the rotating shaft 801 are on the same plane. The transmission belt can drive the two sets of pulleys 701 to rotate. One end of the rotating shaft 801 is rotatably connected to a U-shaped block to prevent the rotating shaft 801 from shaking when rotating. When the motor 8 is started, the rotating shaft 801 connected to the output end of the motor 8 begins to rotate. The pulley 701 at one end of the rotating shaft 801 rotates, and through the transmission belt, the pulley 701 on the surface of the sleeve 7 rotates, and the sleeve 7 rotates accordingly.

[0031] A scale 9 is fixedly connected to one side of the limiting plate 5, and a measuring ruler 10 is connected to one side of the scale 9. The measuring ruler 10 is installed on the upper surface of the placement platform 2. When the limiting plate 5 starts to move to the left, the scale 9 moves along one side of the measuring ruler 10. After the limiting is completed, the scale 9 points to the number on the measuring ruler 10, which can show the deviation between SMT components while calibrating.

[0032] Working principle: When using this device, the SMT chip is first placed on the placement platform 2. Then, the electromagnet 303 is energized, making it magnetic. Subsequently, the armature 403 inside the fixing block 402 is attracted by the electromagnet 303. The armature 403 is embedded inside the fixing block 402, allowing the armature 403 to drive the fixing block 402 and the second connecting rod 401 to move. As the second connecting rod 401 moves, the limiting block 4 can limit both sides of the SMT chip, thereby straightening the tilted SMT chip. The armature 403 on the front of the moving block 602 is attracted by the electromagnet 303. The adsorption causes the moving block 602 to move to the left and be attracted by the electromagnet 303, which in turn drives the limiting plate 5 to limit the SMT component. When the moving block 602 contacts the connecting block 302, the other side of the SMT component does not contact the limiting block 3. Then the motor 8 is started, and the sleeve 7 drives the lead screw 601 to rotate through the transmission belt, so that the limiting plate 5 continues to move to the left, thereby bringing one side of the SMT component into contact with the limiting block 3. After the limitation is completed, by observing the number on the measuring ruler 10 pointed to by the scale mark 9, the deviation between the SMT components can be seen during calibration.

[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
