Description

Technical Field

[0001] The invention relates to the technical field of electronic product assembly, and in particular to an adjustment mechanism and an assembly device. Background Art

[0002] Electronic products come in various shapes, and their assembly angles are mostly multi-angle cross-assembly. In automated equipment, materials are generally placed in a carrier, and the carrier is tilted to a suitable angle for assembly. In related technologies, the torque of the motor is transmitted to the carrier through a coupling. However, during the assembly process, the carrier needs to rotate frequently at multiple angles, so the coupling also needs to be started and stopped suddenly frequently. Frequent starts and stops will cause the diaphragm to withstand repeated stress cycles, which may cause metal fatigue and cause the diaphragm to crack or break. When suddenly started, due to inertia, the large mass load will generate a large impact force. If this impact exceeds the design limit of the diaphragm, the diaphragm may be permanently deformed, thereby affecting its compensation ability and transmission accuracy. Summary of the invention

[0045] Electronic products come in various shapes, and their assembly angles are mostly multi-angle cross-assembly. In automated equipment, materials are generally placed in a carrier, and the carrier is tilted to a suitable angle for assembly. In related technologies, the torque of the motor is transmitted to the carrier through a coupling. However, during the assembly process, the carrier needs to rotate frequently at multiple angles, so the coupling also needs to be started and stopped suddenly frequently. Frequent starts and stops will cause the diaphragm to withstand repeated stress cycles, which may cause metal fatigue and cause the diaphragm to crack or break. When suddenly started, due to inertia, the large mass load will generate a large impact force. If this impact exceeds the design limit of the diaphragm, the diaphragm may be permanently deformed, thereby affecting its compensation ability and transmission accuracy.

[0046] The present invention proposes an adjustment mechanism, aiming to provide an adjustment mechanism with high rotation accuracy, large load, and more suitable for high torque, high precision, and high-speed start and stop scenarios.

[0047] See also Figures 1 to 3In one embodiment of the present invention, the adjustment mechanism 100 includes a first driving device 1, an adjustment component and a transmission structure, wherein the first driving device 1 includes a first driving part 11 rotatably arranged around a rotation axis in the first direction; the adjustment component includes a mounting seat 2 and a fixing tool 3 for fixing a material product, and the fixing tool 3 is rotatably mounted on the mounting seat 2 around a rotation axis in the second direction; the transmission structure is transmission-connected between the first driving part 11 and the mounting seat 2, and the transmission structure includes a connecting member 6, and a first connecting part 4 and a second connecting part 5 spaced apart in the first direction, the first connecting part 4 is fixed to the first driving part 11, and the second connecting part 5 is fixed to the mounting seat 2; wherein a first connecting hole 4a is opened at one end of the first connecting part 4 toward the second connecting part 5, and a second connecting hole 5a is opened at one end of the second connecting part 5 toward the first connecting part 4, and two ends of the connecting member 6 are respectively penetrated through the corresponding first connecting hole 4a and the second connecting hole 5a.

[0048] It should be noted that the first driving device 1 includes the first driving part 11, which can rotate around a rotation axis in a specific direction (referred to as the "first direction"). The first driving part 11 can be a power output shaft of an electric motor, a hydraulic motor or other types of driving sources.

[0049] The adjustment component comprises:

[0050] The mounting seat 2 is a fixed structure used to support the adjustment assembly.

[0051] The fixing fixture 3 is generally configured as a clamp or a bracket to fix the object to be adjusted, such as a material product. The fixing fixture 3 can rotate relative to the mounting seat 2 around a rotation axis in another direction (referred to as the "second direction"), so that the material product can be adjusted with multiple degrees of freedom on two different axes.

[0052] The transmission structure comprises:

[0053] The first connecting portion 4 is fixedly connected to the first driving portion 11 , and a first connecting hole 4 a is formed at one end facing the second connecting portion 5 .

[0054] The second connection portion 5 is fixedly connected to the mounting seat 2 , and has a second connection hole 5 a formed at one end thereof facing the first connection portion 4 .

[0055] The connecting member 6 connects the first connecting portion 4 and the second connecting portion 5 to achieve power transmission.

[0056] At the same time, the fixing device 3 fixed on the mounting seat 2 can rotate around the rotation axis in the second direction, so as to adjust the angle of the material product in multiple directions.

[0057] In the technical solution of the present invention, the mass of the fixing tool 3 is very large. When the first driving device 1 needs to start and stop suddenly, the inertia of the fixing tool 3 is also relatively large. The connecting member 6 can be fine-tuned with the first connecting hole 4a and the second connecting hole 5a, and while absorbing part of the inertial force, sufficient rigidity is ensured to transmit the required torque to ensure the accuracy of torque transmission, so as to provide an adjustment mechanism 100 with high rotation accuracy, large load, and more suitable for high torque, high precision, and high-speed start and stop scenarios.

[0058] For further information, see Figure 2 and Figure 3 In this embodiment, the connecting member 6 is transitionally matched with the first connecting hole 4a and the second connecting hole 5a.

[0059] Both ends of each of the connecting members 6 pass through the corresponding first connecting hole 4a and the second connecting hole 5a respectively, and are transition fit, which means that the connecting member 6 can have a certain movable space in the hole but will not be loose enough to affect the overall stability.

[0060] When the first driving part 11 rotates around the rotation axis in the first direction, the torque is transmitted to the mounting seat 2 through the connecting member 6 in the transmission structure. Due to the transition fit between the connecting member 6 and the first connecting hole 4a and the second connecting hole 5a, this connection mode allows a certain amount of fine adjustment, while also ensuring sufficient rigidity to transmit the required torque.

[0061] For further information, see Figure 2 and Figure 3 In this embodiment, the connecting member 6 is non-rotatably engaged with the first connecting hole 4a and / or the second connecting hole 5a.

[0062] A "lock fit" is a mechanical fit that prevents relative rotation between two parts. This fit is often used in applications where it is necessary to ensure that the two parts remain in a fixed position after assembly. Lock fits can be achieved in a variety of ways, including form fit, keyway fit, pin fixation, etc.

[0063] In a specific embodiment, the connecting member 6 and the first connecting hole 4a have mutually matching anti-rotation surfaces; and / or the connecting member 6 and the second connecting hole 5a have mutually matching anti-rotation surfaces.

[0064] More specifically, the first connection hole 4a is configured as a semicircular hole or a square hole; and / or the second connection hole 5a is configured as a semicircular hole or a square hole.

[0065] It should be noted that one side of the semicircular hole is straight and the other side is semicircular. This shape does not allow the connecting member 6 (such as a pin, a shaft, etc.) to rotate within a certain range to provide sufficient supporting force to transmit torque.

[0066] The shape of the square hole is a square or a rectangle. This shape does not allow the connector 6 to rotate in the hole, thereby ensuring a more stable connection.

[0067] Different hole shapes affect the contact area between the connector 6 and the hole wall, thereby affecting the stress distribution. The semicircular hole may provide better stress dispersion in some applications due to its arc portion, while the square hole may provide stronger support in a specific direction.

[0068] By setting the first connection hole 4a and / or the second connection hole 5a as a semicircular hole or a square hole, the most suitable hole shape can be selected according to the requirements of actual application.

[0069] Of course, the first connecting hole 4a and the second connecting hole 5a can be set as hexagonal holes to cooperate with the connecting member 6 with a hexagonal cross-section to prevent rotation.

[0070] Specifically, see Figure 1 and Figure 4 In this embodiment, the first driving device 1 includes a first motor 12 and a reducer 13, the first motor 12 includes a rotor, the reducer 13 has an input shaft and an output shaft, the input shaft is fixedly connected to the rotor, and the output shaft forms the first driving part 11.

[0071] The first motor 12 is configured as a rotary servo motor, which is an electric motor capable of precisely controlling position, speed and acceleration. The rotor is a rotating component inside a rotary servo motor, usually consisting of a permanent magnet or windings. When current passes through the windings, a magnetic field is generated, which interacts with the magnetic field of the stator (fixed part) to rotate the rotor. It monitors the actual position through a feedback system (such as an encoder) and compares it with the set value to achieve precise position control.

[0072] The reducer 13 is used to reduce the output speed of the servo motor and increase the output torque. The input shaft is a part of the reducer 13 and is directly connected to the rotor of the servo motor. The input shaft receives power from the servo motor. The output shaft is another part of the reducer 13, which transmits power to an external load after gear ratio conversion. The output shaft forms the first drive unit 11, which is the part that is ultimately used to drive the adjustment component.

[0073] It should be noted that servo motors are usually equipped with built-in or external feedback devices (such as encoders) to detect the actual position and speed of the motor. The control system adjusts the current of the servo motor according to the set target value and feedback information to ensure that the output shaft moves in the predetermined manner.

[0074] By setting the rotary servo motor in combination with the reducer 13, very high positioning accuracy and repeatability can be achieved, and motion parameters such as speed, acceleration and stop position can be easily changed through programming. The servo motor has the characteristics of fast response and is suitable for application scenarios that require frequent start and stop or rapid changes. The reducer 13 improves the overall stability of the system and reduces wear caused by high-speed operation. Such a setting improves the stability and carrying capacity of the system, allowing the servo motor to provide greater torque at a lower speed, which is suitable for applications requiring high precision and high torque.

[0075] Specifically, in order to achieve a stable connection between the first connecting portion 4 and the first driving portion 11, please refer to Figure 3 and Figure 4 In this embodiment, a mounting hole 4b is provided on the first connecting part 4, and the first connecting part 4 is sleeved on the periphery of the first driving part 11; the first connecting part 4 includes a connecting body 41, and two clamping arms provided at one end of the connecting body 41 in the first direction, and the two clamping arms 42 are respectively provided on both sides of the mounting hole 4b, and each of the clamping arms 42 has a first end and a second end which are located in the circumferential direction of the mounting hole 4b, the first ends of the two clamping arms 42 are connected to the connecting body 41, and the second ends of the two clamping arms 42 can be arranged to approach and move away from each other in the circumferential direction of the mounting hole 4b, and the second end of each of the clamping arms 42 is provided with an adjusting hole 42a, and the second ends of the two clamping arms 42 are connected by a connecting structure which passes through the two adjusting holes 42a.

[0076] It is understandable that the first connecting part 4 is provided with a mounting hole 4b, and the mounting hole 4b is used to sleeve the first connecting part 4 on the periphery of the first driving part 11. The first connecting part 4 is a ring-shaped or similarly shaped component, which can be installed around the first driving part 11 (i.e., the output shaft of the reducer 13).

[0077] In addition to the mounting hole 4b, two adjustment holes 42a are further provided on the first connecting portion 4. The two adjustment holes 42a are used to adjust the distance between the second ends of the two clamping arms through the connecting member 6, thereby adjusting the clamping force of clamping the first driving portion 11, so as to fix the first connecting portion 4 and the first driving portion 11 together.

[0078] Since the rigid connection has high rigidity and stability, it is suitable for high-precision and high-load applications. This connection method not only provides mechanical fixation, but also ensures the effective transmission of torque, so that the rotational movement of the first driving part 11 can be accurately transmitted to the first connecting part 4, and then to the adjusting component.

[0079] It is understandable that if a certain component needs to be replaced or maintained, it can be done by removing the connecting member 6 without completely disassembling the entire system.

[0080] For further information, see Figure 4 In this embodiment, the first driving part 11 is anti-rotationally matched with the mounting hole 4b. The anti-rotational match can be achieved in many ways, including shape fit, keyway fit, pin fixation, etc.

[0081] In a specific embodiment, the first driving part 11 and the mounting hole 4b have mutually matching anti-rotation surfaces. More specifically, the mounting hole 4b is set as a semicircular hole or a square hole, and correspondingly, the cross section of the first driving part 11 is set as a semicircular or square. In this way, because at least one side of the semicircular hole and the square hole is set as a straight side surface, strict positioning is provided to prevent any rotation, which is suitable for applications requiring high precision and stability.

[0082] Further, in order to fix the adjustment assembly on the second connecting portion 5, please refer to Figure 1 In this embodiment, a socket (not shown) is provided on the second connecting portion 5; a connecting shaft is provided on the mounting seat 2, and the connecting shaft is inserted into the socket, and the connecting shaft and the socket are anti-rotationally engaged.

[0083] It can be understood that at least one socket is provided on the second connecting portion 5. The socket is used to receive the connecting shaft from the mounting seat 2. The socket ensures that the connecting shaft can be inserted accurately and firmly.

[0084] One or more connecting shafts are arranged on the mounting seat 2. The connecting shafts can be inserted into the sockets on the second connecting portion 5. The shape, size and position of the connecting shafts should match the sockets to ensure that the two can fit tightly.

[0085] By inserting the connecting shaft into the jack on the second connecting part 5, the second connecting part 5 is fixed to the mounting seat 2, and the connection has high rigidity and stability, which is suitable for high-precision and high-load applications. Such installation provides mechanical fixation and ensures effective transmission of torque.

[0086] If a component needs to be replaced or maintained, it can be done by disassembling the connecting shaft without completely disassembling the entire system. At the same time, different types of connecting shafts and sockets can be selected according to the needs of actual applications to meet different working conditions and performance requirements.

[0087] Further, in this embodiment, the insertion hole is configured as a square hole, and the connecting shaft is adapted to the square hole.

[0088] The insertion hole provided on the second connecting portion 5 is a square hole, and the connecting shaft on the mounting seat 2 is in a shape matching the square hole. Therefore, the cross section of the connecting shaft is also square or rectangular to ensure that it can be tightly inserted into the square hole.

[0089] The square hole and the square of the connecting shaft provide strict positioning, preventing any rotation, suitable for applications requiring high precision and stability. Due to the tight fit between the square hole and the connecting shaft, torque can be effectively transmitted, reducing energy loss and vibration.

[0090] Further, in this embodiment, the connecting shaft and the square hole are interference fit.

[0091] It is understood that interference fit means that the dimensions of the two parts (the connecting shaft and the square hole) are designed so that when they are assembled together, the outer diameter of the connecting shaft is slightly larger than the inner diameter of the square hole. In this way, a certain amount of interference will be generated during the assembly process, so that the two are tightly combined.

[0092] The interference fit can provide extremely high rigidity and stability, reducing the relative movement between the components. Since there is interference between the connecting shaft and the square hole, it is not easy to loosen or fall off during use. The interference fit can effectively transmit torque and reduce energy loss and vibration.

[0093] Specifically, see Figure 1 and Figure 5 In this embodiment, the fixing tool 3 has a connecting end and a free end in the first direction, and the connecting end of the fixing tool 3 is rotatably mounted on the mounting seat 2 around a rotation axis in the second direction; the adjusting assembly also includes a second driving device 7, and the second driving device 7 includes a second driving part movably arranged along a third direction, and the second driving part is used to drive the free end of the fixing tool 3 to rotate around its connecting end.

[0094] It can be understood that one end of the fixing fixture 3 is called a connecting end, which is rotatably mounted on the mounting seat 2 around the rotation axis in the second direction. The other end of the fixing fixture 3 is called a free end, which can be driven by the second driving device 7 to rotate around the connecting end.

[0095] The connecting end of the fixing fixture 3 is rotatably mounted on the mounting seat 2 around the rotation axis in the second direction, which means that the fixing fixture 3 is mounted on the shaft via a bearing or other rotating mechanism, thereby realizing rotation around the axis.

[0096] The second driving device 7 comprises a second driving part movably arranged along a third direction. The "third direction" refers to another direction different from the first direction and the second direction, that is, a direction perpendicular to the first two directions.

[0097] The function of the second driving part is to drive the free end of the fixing tool 3 to rotate around its connection end. This can be achieved in many ways, such as by push-pull, rotation or other mechanical transmission methods.

[0098] By combining the first driving device 1 and the second driving device 7, the fixing fixture 3 can be adjusted in multiple directions, providing greater flexibility and adaptability. The second driving device 7 can provide precise driving to ensure that the fixing fixture 3 can be adjusted according to a predetermined angle and position. Moreover, such a configuration has a compact structure and can achieve complex multi-axis adjustment in a limited space, which is suitable for applications with limited space.

[0099] Specifically, see Figure 5 In this embodiment, the second driving device 7 includes a cylinder, the cylinder includes a cylinder rod, and the second driving part includes the cylinder rod.

[0100] It is understandable that the second drive device 7 uses a cylinder as a power source. A cylinder is an actuator that uses compressed air or gas to generate linear motion. There is a retractable rod inside the cylinder, called a cylinder rod. The cylinder rod can reciprocate along its axis in the cylinder.

[0101] One end of the cylinder rod is connected to the free end of the fixing fixture 3. When the cylinder rod is extended or retracted, it pushes or pulls the free end of the fixing fixture 3, so that the fixing fixture 3 rotates around its connection end. Since the connection end of the fixing fixture 3 is mounted on the mounting seat 2 around the rotation axis in the second direction, the telescopic movement of the cylinder rod is converted into an angle change of the fixing fixture 3.

[0102] By accurately controlling the extension and retraction amount of the cylinder rod, the angle of the fixing fixture 3 can be accurately adjusted, so that the fixing fixture 3 can be adjusted according to a predetermined angle and position.

[0103] Because the cylinder has a high response speed and can complete the extension and retraction action in a short time, it is suitable for applications that require fast response. In addition, the pneumatic system has a simple structure, easy maintenance, high reliability, and is suitable for various industrial environments. Through solenoid valves and other control devices, precise control of cylinder movement can be easily achieved. Compared with electric or hydraulic drives, pneumatic systems are generally lower in cost and more energy efficient.

[0104] Further, in order to achieve the displacement in the first direction, please refer to Figure 5 In another embodiment, the adjusting mechanism 100 further includes a third driving device 8, wherein the third driving device 8 includes a third driving portion movably arranged along the first direction, and the third driving portion is fixedly connected to the first driving device 1 to drive the first driving device 1 to move along the first direction.

[0105] The third driving device 8 is a newly added component in the adjusting mechanism 100, and its main function is to provide linear motion along the first direction. The third driving device 8 includes a third driving part that is movably arranged along the first direction. The third driving part can be a slider, a piston or other parts that can perform linear motion.

[0106] The third driving device 8 is connected to the first driving device 1 , and when the third driving device moves along the first direction, the first driving device 1 is driven to move together, so that the position of the entire system can be adjusted in the first direction.

[0107] By combining the first drive device 1 (responsible for rotation around the first direction), the second drive device 7 (responsible for rotation of the fixed tool 3 around the second direction) and the third drive device 8 (responsible for linear movement along the first direction), the adjustment mechanism 100 can achieve complex multi-axis adjustment.

[0108] For example, the first driving device 1 can control the rotation angle of a certain component, the second driving device 7 can control the tilt angle of the fixing tool 3, and the third driving device 8 can control the positions of these components in the first direction.

[0109] By introducing the third drive device 8, the adjustment mechanism 100 can perform precise position and angle adjustment in multiple directions, providing higher flexibility and adaptability. In addition, the third drive device 8 can provide precise linear motion to ensure that the position adjustment of the first drive device 1 in the first direction reaches the required accuracy. Integrating multiple drive devices into one adjustment mechanism 100 can simplify the overall structure and improve the compactness and reliability of the system.

[0110] Specifically, in this embodiment, the third driving device 8 includes a second motor, the second motor includes a mover, and the third driving unit includes the mover.

[0111] It is understandable that the third drive device 8 uses a second motor as a power source. The second motor is an electric motor that converts rotational motion into linear motion. The second motor generates linear motion through electromagnetic interaction between a stator (fixed part) and a mover (moving part). When current passes through the stator winding, a magnetic field is generated, which interacts with the permanent magnet on the mover to push the mover to move along the linear guide. By changing the direction and magnitude of the current, the moving direction, speed and position of the mover can be accurately controlled, which can provide high-precision position control and fast response.

[0112] The second motor can be set as a linear servo motor. By adopting a linear servo motor, because of its very high position control accuracy, it can usually achieve micron-level or even sub-micron-level positioning accuracy, so that fine adjustment of the fixed tooling 3 in the first direction can be achieved. At the same time, the linear servo motor has a fast response speed and can adjust the position quickly, which is suitable for applications that require fast response. Since there are no intermediate links such as gears and belts in the mechanical transmission chain, the linear servo motor can provide very smooth and stable linear motion.
