Description

Technical Field

[0001] This utility model relates to the field of chip mounter technology, specifically to a large-stroke plug mounting mechanism. Background Technology

[0002] In the field of electronic equipment manufacturing and automated testing, connector bonding mechanisms play a crucial role, widely used to connect circuit boards, testing equipment, and other electronic components requiring precise mating. Traditional connector bonding mechanisms are often limited by their travel range and rotational flexibility, making it difficult to meet the growing demands for precise mating and diverse connections. Especially in applications involving the R-axis, traditional mechanisms often cannot achieve large-travel rotational mating, thus limiting their applicability in the assembly and testing of complex electronic equipment.

[0003] Travel limitations: Traditional mechanisms typically have limited rotational travel, making it difficult to meet the demands of large-angle, wide-range rotational docking. This results in traditional mechanisms falling short in situations requiring significant adjustments to the docking position or angle.

[0004] Insufficient Precision: In the manufacturing and testing of precision electronic equipment, the accuracy of mating is crucial. However, traditional R-axis rotary plug-in mechanisms often struggle to guarantee high-precision positioning during rotation, which can affect the performance and reliability of the equipment.

[0005] Complex structure: In order to achieve the rotation function, traditional mechanisms often use complex transmission mechanisms and components, which not only increases manufacturing costs, but may also lead to failure and wear during long-term use.

[0006] Poor adaptability: With the continuous upgrading and iteration of electronic devices, the adaptability requirements for plug-in mechanisms are also increasing. Traditional mechanisms often struggle to quickly adapt to new connection needs and specification changes, thus limiting their application in a wider range of fields. Summary of the Invention

[0032] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them.

It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Example

[0033] like Figure 1-7 As shown, this utility model provides a long-stroke plug-in mechanism, including:

[0034] The frame 1 is vertically set, and a horizontal platform 2 is set on the frame 1. The platform 2 is equipped with several spline rods 4, and the spline rods 4 are movably connected to the platform 2.

[0035] The linear motion structure includes a spline seat 3, a track 10, a slider 11, and a long-stroke transmission module. The spline seat 3 is fixedly connected to the surface of the slider 11, and the slider 11 is engaged with the track 10 and slidably connected to the track 10. The long-stroke transmission module is fixedly connected to the spline seat 3 and drives the spline seat 3 to move up and down. The long-stroke transmission module includes a second motor 12, a third synchronous pulley 14, a first transmission belt 16, a transmission block 22, and a pressure block 23. The second motor 12 is located at the top of the frame 1, and a second synchronous pulley 13 is connected to the rotor of the second motor 12. The third synchronous pulley 14 is located below the second synchronous pulley 13. The first transmission belt 16 is pin-connected to the second synchronous pulley 13 and the third synchronous pulley 14. The first transmission belt 16 moves synchronously with the third synchronous pulley 14. A transmission rod 15 is inserted at the shaft of the third synchronous pulley 14. The transmission rod 15 is fixed with the fourth synchronous pulley 17. A fifth synchronous pulley 19 is arranged below the fourth synchronous pulley 17. The fifth synchronous pulley 19 is pin-connected to the fourth synchronous pulley 17 with the second transmission belt 21. The third synchronous pulley 14 drives the fourth synchronous pulley 17 through the transmission rod 15, thereby moving the second transmission belt 21. The transmission block 22 is arranged on the back of the spline seat 3. The transmission block 22 is fixed on the second transmission belt 21 by the pressure block 23.

[0036] The rotating structure includes a spline sleeve 5, a first motor 6, and a third transmission belt 33. The spline sleeve 5 is fitted onto the spline rod 4 and is fixedly connected to the spline rod 4. The first motor 6 is fixed to the side of the platform 2. A first synchronous pulley 7 is provided on the rotor of the first motor 6. The first synchronous pulley 7 drives the spline sleeve 5 to rotate through the third transmission belt 33 connected by a pin.

[0037] The first pulley seat 18 and the second pulley seat 20 are respectively located on one side of the fourth synchronous pulley 17 and the fifth synchronous pulley 19. Their main function is to support and guide the synchronous belt (i.e., the second transmission belt 21). During transmission, the synchronous belt needs to maintain a certain tension and stability. The pulley seats are designed to ensure that the synchronous belt can smoothly pass over the synchronous pulleys, reducing the sway and vibration of the synchronous belt, thereby improving the accuracy and stability of the transmission.

[0038] Spline rod 4 and quick-release head 8: The movable connection between the spline rod 4 and the platform 2 and the design of the quick-release head 8 make it easy to install and replace different air clamp kits 9 or suction head kits 24 to adapt to different operational needs.

[0039] Linear movement and rotary movement: The linear movement structure enables the splined seat 3 and the load to move up and down via a long-stroke transmission module, while the rotary movement structure enables the splined sleeve 5 and the load to rotate via the first motor 6 and the third transmission belt 33. This combination of linear and rotary motion capabilities allows the mechanism to perform complex tasks.

[0040] The first sensor 34 and the sensing plate 31 are designed to calibrate the deflection angle of the spline rod 4, ensuring the accuracy of the rotational motion. The second sensor 35 and the blocking plate 36 are used to detect the highest position of the spline seat 3 and the load, preventing it from exceeding the design range.

[0041] See Figure 1 , Figure 2 and Figure 7 The lower end of the spline rod 4 is provided with a quick-release head 8, which is connected to an air clamp kit 9 ​​or a suction head kit 24.

[0042] The quick-release head 8 is designed to allow operators to quickly and easily change the pneumatic clamp kit 9 ​​or the suction head kit 24. The locking and releasing mechanism of the quick-release head 8 ensures the stability and safety of the tool change process.

[0043] The air clamp kit 9 ​​is typically used to clamp and secure objects of various shapes and sizes, while the suction head kit 24 is suitable for adsorbing and moving lightweight or flat objects. By connecting different tool kits via the quick-release head 8, the mechanism can flexibly adapt to a variety of tasks, improving its versatility and practicality.

[0044] The ability to quickly change tools means that operators can complete tool changes in less time, thereby reducing downtime and improving overall work efficiency. Furthermore, the efficient clamping and suction capabilities of the air clamp kit 9 ​​and suction head kit 24 also contribute to faster work.

[0045] See Figure 1 and Figure 4 Platform 2 is equipped with an idler wheel 30, which is located between spline sleeves 5 to change the direction of the third transmission belt 33, thereby increasing the contact area between the third transmission belt 33 and the spline sleeves 5 and the first synchronous pulley 7.

[0046] The idler pulley 30 allows the transmission direction of the third transmission belt 33 to change, adapting to the complex transmission requirements of the mechanism. By changing the direction of the transmission belt through the idler pulley 30, the contact area between the third transmission belt 33 and the spline sleeve 5 and the first synchronous pulley 7 is increased. A larger contact area means better frictional contact and more stable transmission, which helps reduce slippage and wear during transmission, improving the reliability and lifespan of the transmission.

[0047] The increased contact area not only improves transmission stability but also helps optimize transmission efficiency. A larger contact area allows for more efficient power transmission, reduces energy loss, and thus improves the overall operating efficiency of the mechanism.

[0048] In some space-constrained or complex mechanical systems, the use of idler pulleys 30 allows for more flexible design of the transmission belt path. By cleverly arranging the idler pulleys 30, various complex transmission layout requirements can be adapted to ensure the smooth operation of the mechanism.

[0049] The idler pulley 30 can also reduce shock and vibration during transmission to a certain extent. When the transmission belt passes over the idler pulley 30, its movement trajectory becomes smoother, which helps to reduce shock and vibration caused by sudden changes in direction, and improves the stability and service life of the mechanism.

[0050] See Figure 4 A first sensor 34 is provided on one side of the spline sleeve 5. A sensing plate 31 is provided on the spline sleeve 5. A notch 32 is provided on the sensing plate 31. The first sensor 34 is located on one side of the spline sleeve 5 and is fixedly connected to the platform 2. The sensing point of the sensor is aligned with the sensing plate 31. The notch 32 of the sensing plate 31 is used to calibrate the deflection angle of the spline rod 4.

[0051] The combined design of the sensing plate 31 and the notch 32 allows the first sensor 34 to accurately detect the rotational position of the spline sleeve 5, especially its deflection angle. When the spline sleeve 5 rotates, the sensing plate 31 moves accordingly, and the appearance and disappearance of the notch 32 triggers a change in the sensor's signal, thereby enabling precise measurement and calibration of the deflection angle.

[0052] By calibrating the deflection angle of the spline rod 4, this design can significantly improve the positioning accuracy of the mechanism. In automated operations, precise positioning is a key factor in ensuring work quality and efficiency. The combination of the first sensor 34 and the sensing plate 31 ensures that the spline sleeve 5 and the load reach the predetermined position during rotation, thereby achieving high-precision operation.

[0053] The first sensor 34 can monitor the rotational state of the spline sleeve 5 in real time and feed the signal back to the control system. This real-time monitoring capability helps to detect and correct potential positioning errors in a timely manner, ensuring that the mechanism can operate stably and reliably.

[0054] See Figure 6 A blocking plate 36 is provided on the top of the spline base 3, and a second sensor 35 is provided at the highest point that the spline base 3 can reach. When the spline base 3 reaches the highest point, the blocking plate 36 can just enter the sensing range of the second sensor 35.

[0055] When the spline holder 3 rises to its highest reach, the blocking plate 36 will fall precisely within the sensing range of the second sensor 35. This action triggers the sensor to generate a signal, which the control system can use to confirm that the spline holder 3 has reached the predetermined highest position.

[0056] By incorporating the second sensor 35 and the stop plate 36, damage to other parts of the mechanism due to overshoot during the upward movement of the spline holder 3 can be effectively prevented. Once the spline holder 3 reaches its highest point and triggers the sensor, the control system can immediately stop or reverse the drive motor, thereby avoiding further upward movement and potential damage.

[0057] See Figure 1 It also includes a housing 41, which encloses the frame 1, the linear movement structure, and the rotation structure.

[0058] The housing 41 isolates the internal components of the mechanism from the external environment, providing effective mechanical protection. This prevents damage to the internal components from external physical impacts, bumps, or collisions, ensuring the stability and durability of the mechanism. The housing 41 protects the internal components from external factors such as dust and moisture.

[0059] See Figure 1 The frame 1 is provided with a first rotating wheel seat 18 and a second rotating wheel seat 20. The first rotating wheel seat 18 is located on one side of the fourth synchronous wheel 17, and the second rotating wheel seat 20 is located on one side of the fifth synchronous wheel 19.

[0060] The first rotating wheel seat 18 and the second rotating wheel seat 20 are respectively located on one side of the fourth synchronous wheel 17 and the fifth synchronous wheel 19, providing necessary support and fixation for the synchronous wheels. This support ensures that the synchronous wheels remain stable during rotation and do not wobble or shift.

[0061] The first pulley seat 18 and the second pulley seat 20 can be used to install corresponding transmission elements such as drive belts or chains, thereby achieving effective transmission with the synchronous pulley. At the same time, these pulley seats also serve a guiding function, ensuring that the transmission elements can move along a predetermined path during transmission.

[0062] During the operation of the mechanism, the synchronous pulley needs to bear the load from the transmission system. By setting the first pulley seat 18 and the second pulley seat 20, part of the load can be distributed to the frame 1, thereby reducing the burden on the synchronous pulley and improving its service life.

[0063] The positions and angles of the first wheel seat 18 and the second wheel seat 20 can be adjusted according to actual needs. This adjustment can optimize the performance of the transmission system, such as improving transmission efficiency and reducing energy loss. At the same time, by adjusting the position and angle of the wheel seats, precise control of the mechanism's motion trajectory can also be achieved.

[0064] In some complex or high-speed transmission systems, the stability and reliability of the synchronous pulley are crucial. By setting up a first pulley seat 18 and a second pulley seat 20, the stability of the synchronous pulley during rotation can be enhanced, reducing the risk of failure due to vibration or impact.
