Technical Field

[0001] This invention relates to the field of mechanical automation technology, and in particular to an adaptive pressing mechanism. Background Technology

[0002] Currently, mechanical automation is rapidly upgrading towards unmanned and intelligent operation. High-precision product assembly scenarios are placing more stringent demands on the accuracy and stability of the pressing process. Existing pressing mechanisms mostly adopt the traditional design of directly driving the pressing block with drive components. This design has strong structural rigidity but insufficient adaptability. Since dimensional tolerances are difficult to completely avoid during product manufacturing, such mechanisms are prone to localized stress concentration during pressing due to product tolerances. This not only fails to guarantee the consistency of the pressed flatness but also often results in uneven pressing. Consequently, it cannot meet the core requirement of pressure-sensitive testing for uniform force distribution and is difficult to match the quality control requirements of high-precision assembly, thus hindering the improvement of yield and efficiency in automated production lines. Summary of the Invention

[0022] Reference Figure 1 This embodiment provides an adaptive pressing mechanism, including a driving device 1 and a pressing device 2; The pressing device 2 includes an adjustment component 20 and a pressure plate component 21. The driving device 1 is disposed on the adjustment component 20, and the pressure plate component 21 is disposed at the end of the adjustment component 20 away from the driving device 1. The adjustment component 20 is used to adjust and adapt the positional deviation and force fluctuation of the pressure plate component 21 during the pressing process of the workpiece to be pressed.

[0023] In the above embodiment, the adaptive pressing mechanism consists of two main parts: a driving device 1 and a pressing device 2. The pressing device 2 further includes an adjusting component 20 and a pressure plate component 21. Spatially, the driving device 1 is located above the entire mechanism and directly mounted on one end of the adjusting component 20; the pressure plate component 21 is located at the other end of the adjusting component 20, away from the driving device 1, forming a longitudinal arrangement of "driving device 1—adjusting component 20—pressure plate component 21," with the pressing device 2 positioned below the driving device 1. The driving device 1 provides the power output required for the pressing operation; the adjusting component 20, as the intermediate structure connecting the driving device 1 and the pressure plate component 21, undertakes the core function of transmitting driving force and achieving dynamic adjustment; the pressure plate component 21 is the part that directly contacts the workpiece to be pressed, performing the actual pressing operation during the pressing process. The three components are connected rigidly or semi-rigidly to form a complete force transmission and adjustment link. When the pressure plate assembly 21 is pressing the part to be pressed, if the force fluctuates due to the positional deviation or surface unevenness of the part to be pressed, the adjustment assembly 20 can sense and respond to these changes in real time. It can fine-tune the posture or position of the pressure plate assembly 21 through its own adjustment capability. Therefore, by adjusting the adjustment assembly 20 to adapt to the dimensional tolerance of the part to be pressed in real time, the problem of pressure concentration during pressing is resolved, and the flatness of the pressed part is ensured. It can adapt to products with different tolerances without additional complex debugging, improve the adaptability of the mechanism, meet the requirements of pressure-sensitive testing and high-precision assembly, and help improve the yield and efficiency of the production line.

[0024] Reference Figures 1-2 In one embodiment, the adjustment assembly 20 includes a connecting plate 201, an adjustment shaft component 202, and a bearing mounting component 203. The connecting plate 201 is connected to the drive device 1. The bearing mounting component 203 is disposed between the connecting plate 201 and the pressure plate assembly 21. The adjustment shaft component 202 is located between the connecting plate 201 and the pressure plate assembly 21, and the adjustment shaft component 202 is movably connected to the bearing mounting component 203.

[0025] In the above embodiment, the adjustment assembly 20 consists of three parts: a connecting plate 201, an adjustment shaft component 202, and a bearing mounting component 203. The connecting plate 201, serving as the upper structure of the adjusting assembly 20, is directly connected to the drive device 1 and is used to receive and transmit motion and force from the drive device 1. The bearing mounting component 203 is located between the connecting plate 201 and the pressure plate assembly 21, serving as a support and positioning element. It has an internal installation space or structural feature for accommodating and guiding the adjusting shaft component 202. The adjusting shaft component 202 is located in the middle area between the connecting plate 201 and the pressure plate assembly 21 and is movably mounted on the bearing mounting component 203. This movable connection is preferably a rotatable connection, allowing the adjusting shaft component 202 to rotate freely relative to the bearing mounting component 203 within a certain angle range. The three components are arranged vertically in the following order: the connecting plate 201 is located at the top, adjacent to the drive device 1; the bearing mounting component 203 is in the middle, fixed below the connecting plate 201 and forming a stable connection with it; the adjusting shaft component 202 passes through or is embedded inside the bearing mounting component 203 and extends downward to indirectly or directly connect to the pressure plate assembly 21. When the adjusting shaft component 202 is subjected to lateral or tilting forces from the pressure plate assembly 21, it can adjust its posture through the rotational connection between itself and the bearing mounting component 203. This converts the local deviations faced by the pressure plate assembly 21 into its own rotational displacement, effectively isolating and compensating for unexpected forces caused by unevenness or positional offset of the surface of the workpiece to be pressed. Through the rotational connection between the adjusting shaft component 202 and the bearing mounting component 203, the pressure plate assembly 21 is endowed with multi-directional adaptive capability, significantly improving the bonding accuracy and stability during the pressing process.

[0026] Reference Figures 1-3 In one embodiment, the bearing mounting component 203 includes a first mounting plate 2030, a second mounting plate 2031, and a plurality of adjusting members 2032. The first mounting plate 2030 is disposed on the pressure plate assembly 21. The second mounting plate 2031 is connected to the side of the first mounting plate 2030 away from the pressure plate assembly 21 through the adjusting members, and the first mounting plate 2030 and the second mounting plate 2031 are arranged at intervals. The connecting plate 201 is disposed between the second mounting plate 2031 and the driving device 1.

[0027] In the above embodiment, the bearing mounting component 203 is composed of a first mounting plate 2030, a second mounting plate 2031, and multiple adjusting members 2032. The first mounting plate 2030 is directly fixedly connected to the pressure plate assembly 21, serving as a support structure on the side closest to the pressure plate assembly 21. The second mounting plate 2031 is connected to the side of the first mounting plate 2030 away from the pressure plate assembly 21 via multiple adjusting members 2032. The two are spatially spaced apart and have no direct rigid connection, relying solely on the adjusting members for mechanical coupling. Specifically, the adjusting members are springs, four in number. Every two springs are respectively located at both ends of the second mounting plate 2031 and connected to corresponding positions on the first mounting plate 2030, thus forming an elastic support system. There are two first mounting plates 2030 and two second mounting plates 2031, arranged perpendicularly to each other in space, i.e., one extends along the X direction and the other along the Y direction, forming an orthogonal layout. The connecting plate 201 is disposed between the second mounting plate 2031 and the drive device 1, and is fixedly connected to the second mounting plate 2031. It is used to receive the motion input from the drive device 1 and transmit it to the entire bearing mounting component 203. This arrangement allows the first mounting plate 2030 to undergo slight displacement or tilting when the pressure plate assembly 21 is subjected to force, while the second mounting plate 2031 absorbs and buffers these changes through the elastic deformation of the spring, while maintaining a stable connection with the connecting plate 201. This achieves effective isolation and adaptive adjustment of positional deviations and force fluctuations during the pressing process.

[0028] Reference Figures 1-3 In one embodiment, there are two first mounting plates 2030, which are arranged opposite to each other on the pressure plate assembly 21. The adjusting shaft component 202 is located between the two opposite first mounting plates 2030. The first mounting plate 2030 includes a first mounting base 2033 and a first bearing connection portion 2034. The first mounting base 2033 is connected to the pressure plate assembly 21. The first bearing connection part 2034 is disposed on the side of the first mounting base 2033 away from the pressure plate assembly 21. A first assembly hole 2035 is formed between the first bearing connection part 2034 and the first mounting base 2033. The first end of the adjusting shaft component 202 is rotatably connected in the first assembly hole 2035.

[0029] In the above embodiment, there are two first mounting plates 2030, which are arranged opposite to each other and fixedly connected to the pressure plate assembly 21 to form a symmetrical support structure. Each first mounting plate 2030 is composed of a first mounting base 2033 and a first bearing connecting part 2034, and the two are integrally formed parts with an overall T-shaped structure. The first mounting base 2033 serves as the basic connecting part and is directly fixedly connected to the pressure plate assembly 21, providing a stable mounting base surface; the first bearing connecting part 2034 is located on the side of the first mounting base 2033 away from the pressure plate assembly 21, and is located in the middle of the first mounting base 2033, protruding in the direction away from the pressure plate assembly 21, thereby forming a T-shaped vertical arm. In the intersection area of ​​the first mounting base 2033 and the first bearing connection 2034, they together form a through first assembly hole 2035. Part of the hole wall is formed by the first bearing connection 2034, and the other part is provided by the first mounting base 2033. The transition between the two adopts a chamfered arc structure to reduce stress concentration and facilitate assembly. The adjusting shaft component 202 is located between two opposing first mounting plates 2030. Its first end is the end of the cross shaft perpendicular to the two first mounting plates 2030 and is rotatably connected in the first assembly hole 2035. Since the two first mounting plates 2030 have the same structure and are symmetrically arranged, the first end of the adjusting shaft component 202 is stably clamped in the first assembly hole 2035 between them, achieving reliable rotational support. This allows the adjusting shaft component 202 to rotate freely around a specific axis under the constraint provided by the first mounting plate 2030. At the same time, the T-shaped structure ensures overall rigidity and assembly accuracy, achieving high-stability angle adjustment and improving the mechanism's response sensitivity and structural reliability.

[0030] Reference Figures 1-3 In one embodiment, there are two second mounting plates 2031, which are arranged opposite to each other on the connecting plate 201. The adjusting shaft component 202 is located between the two opposite second mounting plates 2031. The second mounting plate 2031 includes a second mounting base 2036 and a second bearing connection portion 2037. The second mounting base 2036 is connected to the side of the connecting plate 201 away from the driving device 1. The second bearing connecting part 2037 is disposed on the side of the second mounting base 2036 away from the connecting plate 201. The second bearing connecting part 2037 is spaced between two opposing first mounting bases 2033. The first bearing connecting part 2034 is spaced between two opposing second mounting bases 2036. A second mounting hole 2038 is formed between the second bearing connecting part 2037 and the second mounting base 2036. The second end of the adjusting shaft component 202 is rotatably connected in the second mounting hole 2038.

[0031] In the above embodiment, there are two second mounting plates 2031, which are arranged opposite to each other and fixedly connected to the side of the connecting plate 201 away from the driving device 1, forming a symmetrical support structure. Each second mounting plate 2031 consists of a second mounting base 2036 and a second bearing connecting part 2037, and the two are integrally formed parts with an overall T-shaped structure. The second mounting base 2036 serves as the basic connecting part and is directly fixedly connected to the connecting plate 201, providing a stable mounting interface. The second bearing connecting part 2037 is located on the side of the second mounting base 2036 away from the connecting plate 201 and is located in the middle of the second mounting base 2036, protruding in the direction away from the connecting plate 201 to form a T-shaped vertical arm. In the intersection area of ​​the second mounting base 2036 and the second bearing connection 2037, a through second assembly hole 2038 is formed. Part of the hole wall is formed by the second bearing connection 2037, and the other part is provided by the second mounting base 2036. The connection between the two adopts a chamfered arc structure to reduce stress concentration and improve assembly smoothness. The adjusting shaft component 202 is located between two opposing second mounting plates 2031. Its second end is the end of the cross shaft perpendicular to the two second mounting plates 2031 and is rotatably connected in the second assembly hole 2038.

[0032] Meanwhile, two first mounting plates 2030 are symmetrically arranged on the pressure plate assembly 21 in the same manner. Their first bearing connecting parts 2034 are spaced between the two second mounting bases 2036, while their second bearing connecting parts 2037 are spaced between the two first mounting bases 2033, so that the two sets of mounting plates are perpendicular to each other in space. The adjusting shaft component 202 acts as a cross bearing, and its two perpendicular ends are rotatably connected in the first mounting hole 2035 and the second mounting hole 2038, respectively, so that it is stably supported between the two sets of orthogonal T-shaped mounting plates. Furthermore, the first mounting plate 2030 and the second mounting plate 2031 are connected by a spring, allowing the first mounting plate 2030 to apply elastic pressure to the second mounting plate 2031. When the pressure plate assembly 21 contacts the part to be pressed, if there is a positional deviation or force fluctuation, this structure achieves multi-directional angle adjustment through the rotational degrees of freedom of the cross axis in two orthogonal directions. At the same time, it relies on the spring to provide Z-direction elastic floating support. The synergistic effect ensures that the pressure plate assembly 21 always maintains parallel contact with the surface of the part to be pressed, realizing multi-directional adaptive adjustment and elastic buffering, significantly improving the flatness of the pressing and the uniformity of the force.

[0033] Reference Figures 1-3In one embodiment, the connecting plate 201 includes a connecting base portion 2010 and a snap-fit ​​portion 2011. The connecting base portion 2010 is connected to the driving device 1 and contacts the second mounting plate 2031. The snap-fit ​​portion 2011 is disposed at one end of the connecting base portion 2010 away from the driving device 1, and the snap-fit ​​portion 2011 is disposed within the second mounting plate 2031.

[0034] In the above embodiment, the connecting plate 201 consists of two parts: a connecting base portion 2010 and a snap-fit ​​portion 2011, which together form an integral structure. The connecting base portion 2010 serves as the main body of the connecting plate 201. One end of it connects to the driving device 1, while the other end extends towards and directly contacts the second mounting plate 2031, serving to transmit driving force and provide support. The snap-fit ​​portion 2011 is located at the end of the connecting base portion 2010 furthest from the driving device 1 and in the middle of the connecting base portion 2010, thus giving the entire connecting plate 201 a T-shaped structure. Two opposing second mounting plates 2031 each have a corresponding snap-fit ​​platform on their inner side. These two snap-fit ​​platforms are opposite each other, forming a support interface for receiving and positioning the snap-fit ​​portion 2011. The snap-fit ​​portion 2011 is precisely embedded and overlapped on these two snap-fit ​​platforms, thereby achieving a stable and fixed connection between the connecting plate 201 and the second mounting plate 2031. The connecting base portion 2010 is located on top, adjacent to the drive device 1, and its lower surface is in contact with the upper surface of the second mounting plate 2031. The snap-fit ​​portion 2011 protrudes downward from the middle of the connecting base portion 2010 and is inserted into the gap between the two second mounting plates 2031, finally settling on the snap-fit ​​platform. This structure not only enhances the connection rigidity through surface contact, but also restricts the horizontal displacement of the connecting plate 201 by utilizing the cooperation between the snap-fit ​​portion 2011 and the snap-fit ​​platform. At the same time, the T-shaped design effectively concentrates the load path, improving the mechanical transmission efficiency and assembly stability of the overall structure.

[0035] Reference Figures 1-4 In one embodiment, the adjusting shaft component 202 includes an adjusting shaft body 2020 and a plurality of retaining rings 2021. The adjusting shaft body 2020 is located between the connecting plate 201 and the pressure plate assembly 21, and the adjusting shaft body 2020 is rotatably connected to the bearing mounting component 203. The retaining rings 2021 are engaged in the bearing mounting component 203 and contact the adjusting shaft body 2020.

[0036] In the above embodiment, the adjusting shaft component 202 consists of an adjusting shaft body 2020 and multiple retaining rings 2021. The adjusting shaft body 2020 is a cross bearing, located entirely within the space between the connecting plate 201 and the pressure plate assembly 21, and is assembled in the bearing mounting component 203 as a core rotating element. Both ends of the adjusting shaft body 2020 are respectively inserted through and rotatably connected to the mounting holes formed in the bearing mounting component 203, allowing it to rotate freely in two mutually perpendicular directions, thus giving the entire pressing system multi-directional angular adaptive capability. Multiple retaining rings 2021 are disposed inside the bearing mounting component 203 and contact the outer circumferential surface or ends of the adjusting shaft body 2020. Their main function is to limit the axial movement of the adjusting shaft body 2020, while providing appropriate preload to eliminate gaps and ensure smooth, non-loose rotation. The adjusting shaft body 2020 is centrally located between the connecting plate 201 and the pressure plate assembly 21, with its geometric center roughly in the middle of the distance between the two. The retaining ring 2021 is embedded in the annular groove or positioning step inside the bearing mounting component 203, surrounding or abutting against the corresponding part of the adjusting shaft body 2020, forming a reliable axial limiting structure. Through its cooperation with the bearing mounting component 203, the entire adjusting shaft assembly 202 achieves flexible multi-degree-of-freedom rotation, while the constraint of the retaining ring 2021 ensures structural compactness and motion accuracy, providing crucial mechanical support for the pressure plate assembly 21 to respond in real-time to surface deviations of the workpiece during the pressing process.

[0037] Reference Figures 1-3 In one embodiment, the pressure plate assembly 21 includes a pressure plate body 210 and a pressure plate head 211. The pressure plate body 210 is connected to the end of the adjustment assembly 20 away from the driving device 1, and the pressure plate head 211 is disposed at the end of the pressure plate body 210 away from the adjustment assembly 20.

[0038] In the above embodiment, the pressure plate assembly 21 consists of two parts: a pressure plate body 210 and a pressure plate head 211. The pressure plate body 210 is a rigid structural component, with one end connected to the end of the adjusting assembly 20 furthest from the driving device 1. It serves as the supporting framework for the entire pressure plate assembly 21, transmitting the pressing force and maintaining structural rigidity. The pressure plate head 211 is located at the other end of the pressure plate body 210 furthest from the adjusting assembly 20, at the bottom of the pressure plate assembly 21, directly facing the workpiece to be pressed. It is typically made of a flexible material (such as silicone, polyurethane, or rubber) and is used to contact the product surface during the pressing process. The pressure plate body 210 is positioned above the pressure plate head 211, and the two are arranged vertically in sequence, forming a continuous connection link of "adjusting assembly 20—pressure plate body 210—pressure plate head 211". Specifically, the pressure plate body 210 and the pressure plate head 211 are identical in size, meaning their outlines (such as length, width, or diameter) in planar projection are completely consistent. This allows the pressure plate head 211 to completely cover the entire lower surface of the pressure plate body 210, avoiding localized suspension or stress concentration. This equal-size design not only ensures uniform pressure distribution across the entire contact surface but also simplifies the assembly alignment process and improves the overall consistency and reliability of the structure. The pressure plate body 210 effectively transmits the adjustment action from the adjustment component 20 through its rigidity, while the pressure plate head 211 absorbs minor surface unevenness through its elastic deformation capability. The synergistic effect of both ensures that the pressing process possesses both structural stability and good surface adaptability.

[0039] Reference Figures 1-3 In one embodiment, the driving device 1 includes a driving motor 10 and a driving body 11, the driving body 11 being slidably connected to the driving motor 10, and the connecting plate 201 being disposed at the end of the driving body 11 away from the driving motor 10.

[0040] In the above embodiment, the driving device 1 consists of two parts: a driving motor 10 and a driving body 11. The driving motor 10 is a servo motor, serving as the power source for the entire driving device 1, and possesses high-precision position, speed, and torque control capabilities. The driving body 11 is slidably connected to the driving motor 10, specifically mounted on the output end of the driving motor 10, and can perform precise vertical linear motion under the drive of the driving motor 10. A connecting plate 201 is located at the end of the driving body 11 furthest from the driving motor 10, i.e., on the lower side of the driving body 11, serving as a transitional connector between the driving device 1 and the pressing device 2, used to transmit the linear motion of the driving body 11 to the subsequent pressing structure. The drive motor 10 is located at the top and fixed to the equipment frame or support structure. The drive body 11 is mounted or integrated onto the motion output mechanism (such as a lead screw or linear module) of the drive motor 10 and can slide along its axis. The connecting plate 201 is rigidly connected to the bottom end of the drive body 11. The three are arranged vertically in sequence to form a series structure of "drive motor 10 - drive body 11 - connecting plate 201". This layout ensures efficient transmission of driving force: after the drive motor 10 starts, it drives the drive body 11 to rise and fall smoothly through the internal transmission mechanism. The drive body 11 then directly transmits the motion to the connecting plate 201, thereby driving the entire pressing device 2 to perform the pressing action. By cooperating with the servo motor and the sliding drive body 11, high-precision and high-response linear drive is achieved, ensuring that the pressing process is controllable and reliable.

[0041] Reference Figures 1-3 In one embodiment, the driving device 1 further includes a pressure sensor, which is disposed on the driving body 11 and is used to collect and feedback the pressing contact force signal in real time.

[0042] In the above embodiment, in addition to the drive motor 10 and the drive body 11, the drive device 1 further integrates a pressure sensor. The drive body 11, as a motion actuator, is slidably connected to the drive motor 10 and moves vertically under the drive of the drive motor 10. The pressure sensor is directly mounted on the drive body 11, with its optimal installation position being the output end at the bottom of the drive body 11, or above the connecting plate 201 and in close contact with the drive body 11. This position ensures that the pressure sensor is at a critical node in the force transmission path, enabling it to directly and accurately sense the contact force transmitted from the drive body 11 to the pressing device 2. When the pressing device 2 contacts the workpiece to be pressed and generates a reaction force, this force is transmitted back along the path of "pressing device 2 - connecting plate 201 - drive body 11," and the pressure sensor is precisely located within this path, thus acquiring the actual contact force signal during the pressing process in real time. The collected force data is transmitted to the control terminal in real time as a feedback signal for closed-loop control. The control terminal dynamically adjusts the output parameters (such as current or position commands) of the drive motor 10 based on the deviation between the preset force threshold and the measured value, thereby adjusting the magnitude of the thrust applied by the drive body 11. Through this "sensing-feedback-adjustment" mechanism, the entire system ensures that the pressing force remains stably within the set range. The pressure sensor is embedded or fixed at the interface between the drive body 11 and the connecting plate 201. It does not interfere with mechanical movement and can efficiently capture load changes, forming the core sensing unit in the drive device 1 for high-precision force control. By integrating the pressure sensor on the drive body 11, real-time monitoring and closed-loop control of the pressing contact force are achieved, ensuring accurate and stable pressing force.
