Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly to a rapid alignment device for electronic components. Background Art

[0002] In the production and assembly processes of electronic components, the precise alignment of electronic components is a key link to ensure product performance and quality. Whether it is chip packaging, circuit board soldering, or the assembly of electronic components, it is necessary to accurately place the electronic components in the predetermined positions to ensure normal electrical connection and coordinated operation between components. Precise alignment can not only improve production efficiency but also effectively reduce the rejection rate. Therefore, the rapid alignment device for electronic components has an indispensable position in the field of electronic manufacturing.

[0003] Currently, the common electronic component alignment devices on the market usually use simple mechanical structures or single limiting methods for alignment and fixation. Some devices adjust the position of the slider on the guide rail through a manual knob to achieve the horizontal movement of the component, and rely on a bolt and nut structure to fix the bearing platform on the column in the vertical direction. After alignment, only a few fixing bolts are tightened, and the position of the component is maintained by relying on the friction between the bolt and the mounting hole and the contact pressure between the component surfaces. However, in actual production, there are many problems with this fixing method: on the one hand, a small number of fixing points are difficult to evenly disperse the external force. When the equipment vibrates during operation or is externally impacted, the component is extremely likely to shift due to uneven force; on the other hand, after long-term use, the surface wear of the components will cause the friction force to decrease, resulting in the loosening of the originally fixed components. Once the component is displaced, it will lead to deviations in subsequent assembly, affecting the performance and reliability of the product, and even requiring re-alignment and assembly, increasing production costs and production cycles.

[0004] Therefore, in view of the above problems, a rapid alignment device for electronic components is proposed to solve the above problems. Summary of the Invention

[0005] To make up for the above deficiencies, the present invention provides a rapid alignment device for electronic components, aiming to improve the problems in the prior art that the fixing method is single, the number of fixing points is small, resulting in the component being easily disturbed by external forces and loosening after alignment, and it is difficult to maintain long-term stability.

[0006] To achieve the above object, the present invention adopts the following technical solution: A rapid alignment device for electronic components, including a base, a plurality of columns are fixedly connected to the top of the base, a positioning frame is slidably connected to the outside of the plurality of columns, an adjusting mechanism is arranged inside the positioning frame, a clamping jaw table is arranged at the output end of the adjusting mechanism, and a limiting mechanism is arranged outside the positioning frame; The limiting mechanism includes a plurality of limiting plates. The inner sides of the limiting plates are slidably connected to the outer sides of the positioning frames. The tops of the limiting plates are threadedly connected with setscrews. The inner parts of the limiting plates are fixedly connected with sleeves. The outer walls of the sleeves are fixedly connected with positioning blocks. The adjacent ends of the sleeves are fixedly connected with fixing plates. A plurality of barrier strips are slidably connected to the outer sides of the fixing plates. The ends of the barrier strips are fixedly connected with sliding columns. As a further description of the above technical solution: The limiting mechanism further includes a driving rod. The outer side of the driving rod is threadedly connected to the inner side of the sleeve. The adjacent ends of the driving rod are fixedly connected with a rotating disk. An arc-shaped groove is formed in the outer part of the rotating disk. The outer sides of the sliding columns are slidably connected to the inside of the arc-shaped groove. As a further description of the above technical solution: A plurality of convex grooves are formed in the outer side of the fixing plate. The shapes of the convex grooves are adapted to the sliding sections of the barrier strips. As a further description of the above technical solution: The length of the sliding column is greater than the distance between the end part of the driving rod and the end part of the sleeve, and the outer radius of the sliding column is greater than the width of the arc-shaped groove. As a further description of the above technical solution: The adjusting mechanism includes adjusting blocks. A plurality of sliding grooves are formed in the positioning frames. The upper and lower ends of the adjusting blocks are shaped to be adapted to the sliding grooves. Activity cavities are formed in the upper and lower ends of the adjusting blocks. Adjusting screws are threadedly connected to the inner parts of adjacent adjusting blocks. Follow-up rods are slidably connected to the inner parts of the other two adjusting blocks. The outer part of the jaw table is arranged at the adjacent ends of the two adjusting screws and the two adjusting blocks. A hoop is slidably connected to the outer side of the column, and the top of the hoop is fixedly connected to the bottom of the positioning frame. Scale bars are arranged around the positioning frame. As a further description of the above technical solution: The outer ends of the barrier strips are arc-shaped, and the radius in the unfolded state is greater than the width of the positioning blocks and less than the radius of the activity cavities. As a further description of the above technical solution: Positioning grooves are formed in both sides of the top of the adjusting block. The outer sides of the positioning blocks are detachably connected to the inside of the positioning grooves. As a further description of the above technical solution: The tops of the scale bars are arranged to be rough surfaces. The setscrews penetrate through the limiting plates and the end parts are in close contact with the rough surfaces.

[0007] The present invention has the following beneficial effects: 1. In the present invention, after the adjusting block contacts the limiting plate, the driving rod is rotated to drive the rotating disk to rotate. When the rotating disk rotates, the blocking strip is extended through the action of the arc-shaped groove and the sliding column, and the top screw is used to press the limiting plate tightly, forming a multi-point rigid constraint. Through the cooperative locking structure of the limiting plate and the blocking strip, the beneficial effect of firmly fixing the position after alignment is achieved, thereby effectively resisting external force interference, preventing the adjusting block and the clamping jaw platform from shifting, ensuring the long-term stability after the alignment of the electronic components, and improving the assembly reliability.

[0008] 2. In the present invention, the positioning frame is locked by the hoop to quickly adjust the height of the entire positioning frame. And in the horizontal direction, first, the limiting plate is moved to the specified position according to the scale bar, then the top screw is turned to fix the position of the limiting plate, and then the double adjusting screw rod drives the adjusting block and the clamping jaw platform to move synchronously. Thus, while ensuring that the entire electronic component can freely and stably adjust its orientation in the plane, the adjustment range is restricted by fixing the position of the limiting plate, thereby ensuring the precise position of the electronic component.

[0011] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0012] Refer to Figures 1 to 8, an embodiment provided by the present invention: A rapid alignment device for electronic components, including a base 1. The base 1 is used to carry the entire device, providing a stable support foundation to ensure that the device remains stable when placed on a flat workbench, providing a reliable reference for the operation of subsequent components. A plurality of columns 2 are fixedly connected to its top. The columns 2 are vertically fixed to the top of the base 1, providing vertical guidance for the positioning frame 3, enabling the positioning frame 3 to slide up and down along the columns 2 to achieve height position adjustment. A positioning frame 3 is slidably connected to the outside of the plurality of columns 2. The positioning frame 3 is sleeved outside the columns 2 and can slide, used to carry the adjustment mechanism 4 and the jaw platform 5. By sliding on the columns 2, the overall height is adjusted to provide an adjustable-height working platform for the alignment of electronic components. An adjustment mechanism 4 is provided inside the positioning frame 3. The adjustment mechanism 4 is used to precisely adjust the position of the jaw platform 5 in the horizontal direction, thereby achieving the in-plane position alignment of the electronic components. It includes an adjustment block 401. A plurality of sliding grooves 404 are opened inside the positioning frame 3. The sliding grooves 404 provide tracks for the movement of the adjustment block 401, ensuring the linearity and stability of the movement of the adjustment block 401 in the horizontal direction. The adjustment block 401 is adapted to the sliding grooves 404 and makes a linear motion in the sliding grooves 404 under the action of the adjustment screw 402, driving the jaw platform 5 to move, achieving the adjustment of the position of the jaw platform 5 in the horizontal direction. The moving cavities 407 inside its upper and lower ends provide space for the movement of related components. The shapes of the upper and lower ends of the adjustment block 401 are adapted to the shapes of the sliding grooves 404. Moving cavities 407 are opened inside both the upper and lower ends of the adjustment block 401. An adjustment screw 402 is threadedly connected inside each of the adjacent two adjustment blocks 401. The adjustment screw 402 is threadedly connected to the adjacent adjustment block 401 and converts its own rotation into a linear motion of the adjustment block 401, which is the key transmission component for the adjustment mechanism 4 to achieve horizontal position adjustment. A follower rod 403 is slidably connected inside the other two adjustment blocks 401. The follower rod 403 is slidably connected to the other two adjustment blocks 401. When the adjustment screw 402 drives the adjustment block 401 to move, the follower rod 403 moves in coordination to ensure the synchronism and stability of the movement of the adjustment block 401 and the jaw platform 5, enabling the jaw platform 5 to move freely and stably within the internal space plane of the positioning frame 3. The outside of the jaw platform 5 is arranged at the adjacent ends of the two adjustment screws 402 and the two adjustment blocks 401. The jaw platform 5, as the output end of the adjustment mechanism 4, is used to place and fix electronic components, achieving precise alignment through the adjustment of the adjustment mechanism 4 and having the clamping function to clamp the electronic components. A hoop 405 is slidably connected to the outside of the column 2. The hoop 405 is slidably connected to the outside of the column 2 and its top is fixed to the bottom of the positioning frame 3, used to lock the positioning frame 3 and fix the height position of the positioning frame 3 on the column 2 to achieve vertical position locking. And the top of the hoop 405 is fixedly connected to the bottom of the positioning frame 3. Scale bars 406 are arranged around the positioning frame 3. The scale bars 406 are arranged around the positioning frame 3, providing an intuitive position reference for the operator.It is convenient to accurately adjust the positions of the adjusting block 401 and the jaw table 5 in the horizontal direction, making the adjustment process more accurate and controllable.

[0013] A limiting mechanism 6 is arranged outside the positioning frame 3. The limiting mechanism 6 is used to limit the movement range of the adjusting mechanism 4, lock the adjusted position, ensure the stability of the position of the electronic component after alignment, and prevent displacement caused by external force interference. It includes a plurality of limiting plates 601. The inner side of the limiting plate 601 is slidably connected to the outer side of the positioning frame 3 and can move to a suitable position on the outer side of the positioning frame 3 and is fixed by a setscrew 602. Its function is to limit the movement range of the adjusting block 401 and cooperate with the adjusting block 401 to achieve position locking. The inner side of the limiting plate 601 is slidably connected to the outer side of the positioning frame 3. A setscrew 602 is threadedly connected to the top of the limiting plate 601. The top of the scale bar 406 is set as a rough surface. The setscrew 602 penetrates through the limiting plate 601 and the end part is in close contact with the rough surface. The setscrew 602 is threadedly connected to the top of the limiting plate 601. Rotate the setscrew 602 so that its end part is in close contact with the rough surface at the top of the scale bar 406, and use the friction force to firmly fix the limiting plate 601 on the positioning frame 3 to ensure that the limiting plate 601 does not move when restricting the movement of the adjusting block 401. A sleeve 603 is fixedly connected inside the limiting plate 601. The sleeve 603 is fixedly connected inside the limiting plate 601 to provide guidance and support for the movement of the driving rod 609, so that the driving rod 609 can perform linear motion inside it. A positioning block 604 is fixedly connected to the outer wall of the sleeve 603. Positioning grooves are formed on both sides of the top of the adjusting block 401. The outside of the positioning block 604 is detachably connected to the inside of the positioning groove. The positioning block 604 is fixedly connected to the outer wall of the sleeve 603 and is detachably connected to the positioning groove at the top of the adjusting block 401. After the adjusting block 401 contacts the limiting plate 601, the positioning block 604 is inserted into the positioning groove to further enhance the locking effect of the limiting plate 601 on the position of the adjusting block 401. A fixed disk 605 is fixedly connected to the adjacent end of the sleeve 603. The fixed disk 605 is fixedly connected to the adjacent end of the sleeve 603 to provide support and a track for the sliding of the barrier strip 606, so that the barrier strip 606 can perform stretching and contracting movements on its outside. A plurality of barrier strips 606 are slidably connected to the outside of the fixed disk 605. The outer end of the barrier strip 606 is arc-shaped and slides in the convex groove 607 on the outside of the fixed disk 605. By stretching and contracting, a multi-point rigid constraint on the adjusting block 401 is formed. After alignment, it cooperates with the limiting plate 601 to resist external force interference and prevent the adjusting block 401 and the jaw table 5 from shifting. The outer end shape of the barrier strip 606 is arc-shaped, and the radius in the unfolded state is greater than the width of the positioning block 604 and less than the radius of the moving cavity 407. A plurality of convex grooves 607 are formed on the outside of the fixed disk 605, which are adapted to the shape of the sliding section of the barrier strip 606. A sliding column 608 is fixedly connected to the end of the barrier strip 606. The sliding column 608 is fixedly connected to the end of the barrier strip 606 and is slidably connected to the arc-shaped groove 611 on the rotating disk 610. When the rotating disk 610 moves, the barrier strip 606 is driven to slide on the outside of the fixed disk 605 by sliding in the arc-shaped groove 611, realizing the stretching and contraction of the barrier strip 606.

[0014] The limiting mechanism 6 further includes a driving rod 609. The outer side of the driving rod 609 is threadedly connected to the inner side of the sleeve 603 and makes a linear motion within the sleeve 603 by rotation, driving the rotating disk 610 to move. It is the power input component for controlling the extension and contraction of the barrier strip 606. The outer side of the driving rod 609 is threadedly connected to the inner side of the sleeve 603. The adjacent end of the driving rod 609 is fixedly connected to a rotating disk 610. The rotating disk 610 is fixedly connected to the adjacent end of the driving rod 609. An arc-shaped groove 611 is provided on the outside. It rotates and makes a linear motion under the drive of the driving rod 609. Through the interaction between the arc-shaped groove 611 and the sliding column 608, the motion of the driving rod 609 is converted into the sliding of the barrier strip 606, realizing the adjustment of the extension degree of the barrier strip 606. An arc-shaped groove 611 is provided on the outside of the rotating disk 610. The outer side of the sliding column 608 is slidably connected to the inside of the arc-shaped groove 611. The length of the sliding column 608 is greater than the distance between the end part of the driving rod 609 and the end part of the sleeve 603, and the outer radius of the sliding column 608 is greater than the width of the arc-shaped groove 611.

[0015] Working principle: Place the device on a stable workbench to ensure the stability of the base 1. At this time, the positioning frame 3 is at a certain initial position on the column 2, and the adjusting block 401 and the clamping jaw table 5 in the adjusting mechanism 4 are also in the initial state, and components such as the limiting plate 601 of the limiting mechanism 6 are not adjusted.

[0016] Place the electronic component on the clamping jaw table 5, and then start the clamping jaw table 5 to fix the entire electronic component. And the soft pads provided on the clamping jaws of the clamping jaw table 5 are used to prevent damage to the electronic component. Manually slide the positioning frame 3 up or down to move it on the column 2. The positioning frame 3 makes a linear motion along the column 2 and reaches a roughly appropriate height, and then locks it with the hoop 405 to fix the height of the positioning frame 3, preparing for subsequent precise alignment. [[ID=,9]]

[0017] Then, slide the limiting plate 601 so that it moves outside the positioning frame 3 to a suitable position on the scale bar 406. Rotate the setscrew 602, and the setscrew 602 moves towards the scale bar 406 and presses tightly to fix the limiting plate 601 on the positioning frame 3. Then rotate the adjusting screw 402. Since the adjusting block 401 is in threaded engagement with the adjusting screw 402, the rotation of the adjusting screw 402 will cause the adjusting block 401 on both sides to move linearly in the sliding groove 404 inside the positioning frame 3 by driving the movement of the jaw table 5. And during the movement of the adjusting screw 402, it drives the two follower rods 403 and another adjusting screw 402 to move in the same direction, so as to ensure that the jaw table 5 can move freely and stably in the internal space plane of the positioning frame 3. Thus, through the adjusting function of the two adjusting screws 402 in the horizontal direction and the adjusting function of the hoop 405 in the vertical direction, the entire jaw table 5 can position the electronic components conveniently in three dimensions. At the same time, due to the limiting effect of the limiting plate 601, the adjusting screw 402 is restricted after moving to a certain position, so as to ensure the precise position of the electronic components.

[0018] And when the adjusting block 401 contacts the limiting plate 601, the sleeve 603 and the positioning block 604 are inserted into the top of the adjusting block 401. Then move another limiting plate 601 on the same side to the other side of the adjusting block 401, and then rotate the driving rod 609. When the driving rod 609 rotates, it makes a linear rotational motion in the sleeve 603, driving the rotating disk 610 to move and rotate as well as move linearly. The arc-shaped groove 611 on the rotating disk 610 interacts with the sliding column 608 at the end of the barrier strip 606, causing the sliding column 608 to slide in the arc-shaped groove 611, and then driving the barrier strip 606 to slide in the convex-shaped groove 607 outside the fixed disk 605 to adjust the extension degree of the barrier strip 606. Thus, the position of the adjusting block 401 is fixed by docking the limiting plates 601 on both sides of the adjusting block 401 with the adjusting block 401. Then tighten the setscrew 602 to ensure that the limiting plate 601 does not shake, so as to ensure that the entire jaw table 5 and the electronic components will not move relative to each other due to external forces after alignment, thereby ensuring the stability of alignment.
