Description

Spring mounting mechanism SPRING PIECE MOUNTING MECHANISM Technical Field

[0001] This application relates to the field of automation equipment technology, and in particular to a spring-loaded mechanism. Prior Technology

[0002] Terminal devices typically have buttons on their sides, which are secured to the device's frame by spring-loaded contacts. In the prior art, the assembly of these side button contacts often relies on manual labor, such as workers manually aligning and pressing the contacts into their predetermined positions. Because the contacts themselves are small and the side buttons may be densely packed, manual installation can easily result in the contacts not fully engaging with the buttons or misalignment. Furthermore, the pressure applied manually is inconsistent, which can lead to improper contact installation and affect the contact's displacement accuracy. All of these factors can result in poor button feel and even affect the proper functioning of the buttons. Summary of the Invention

[0003] In view of this, this application provides a spring clip installation mechanism that can improve the installation quality of the spring clip and increase the assembly yield.

[0004] One embodiment of this application provides a spring clip mounting mechanism, including a carrier plate, a positioning fixture, a clamping post, and a locking assembly. The carrier plate has a support platform for supporting a product. The positioning fixture is located on the carrier plate and above the support platform, and has a vertically extending guide groove. A sensor is located on the inner side wall of the guide groove. The clamping post is located on the side of the positioning fixture away from the support platform, and is configured to partially pass through the guide groove and extend to the upper surface of the support platform to clamp the spring clip of the product. The locking assembly is signal-connected to the sensor. When the clamping post is not inserted into the guide groove, the locking assembly locks the position of the positioning fixture relative to the carrier plate. When the clamping post is inserted into the guide groove and triggers the sensor, the locking assembly unlocks the position of the positioning fixture relative to the carrier plate.

[0005] By using sensors to detect whether the clamping pin is accurately inserted into the guide slot, and linking the locking components to control the locking and unlocking of the positioning fixture, this design ensures that the subsequent product removal operation is only allowed after the clamping pin is accurately aligned. This improves the alignment accuracy and process reliability of the spring installation and reduces installation quality problems caused by inaccurate positioning.

[0006] In some alternative embodiments, the fastening post includes a main body, a guide, and a fastening part. The guide connects the main body and the fastening part. The main body is used to connect the robotic arm. The guide engages with a guide groove to trigger a sensor. The fastening part passes through the guide groove and extends to the upper surface of the support platform to press the spring of the product.

[0007] The main body facilitates automated control, the guide section ensures accurate motion trajectory to reliably trigger the sensor, and the fastening section focuses on pressing the spring. This structural division of labor helps improve the stability and force control of the installation action, and enhances the consistency of the installation effect.

[0008] In some alternative embodiments, the spring mounting mechanism further includes a flip plate located above the support platform, with one side of the flip plate hinged to the support plate, a locking component locking or unlocking the other side of the flip plate, and a positioning fixture fixed to the side of the flip plate away from the support platform.

[0009] The flip plate allows the positioning fixture to rotate around the hinge axis, thereby opening up the operating space, facilitating the handling of products and the observation and adjustment of the installation process, thus improving the humanization and convenience of operation.

[0010] In some alternative embodiments, multiple positioning fixtures are provided, and the multiple positioning fixtures are spaced apart on the flip plate and move synchronously with the flip plate.

[0011] By setting up multiple positioning fixtures, multiple installation stations of the product can be simultaneously addressed, enabling the synchronous or sequential installation of multiple spring clips, which significantly improves the efficiency of mass production.

[0012] In some alternative embodiments, the locking assembly includes a mounting base, a drive member, and a locking head. The mounting base is fixed to the carrier plate and has a supporting surface for supporting the lower surface of the flip plate. The drive member is disposed on the mounting base and has a drive end. The locking head is connected to the drive end to have a locked state in which the flip plate extends and blocks it, and an unlocked state in which the flip plate retracts and releases the blockage.

[0013] The mounting base provides support for the flip plate, and the drive unit controls the locking head to achieve precise locking and unlocking actions, which helps to improve the rigidity and stability of the mechanism in the working state.

[0014] In some optional embodiments, the supporting surface is provided with a positioning boss, and the flip plate is provided with a positioning groove, which engages with the positioning boss.

[0015] The snap-fit ​​between the positioning boss and the positioning groove provides precise positioning when the flip plate closes, reduces possible deviations in the closed position, and improves the repeatability of the positioning fixture relative to the carrier plate.

[0016] In some alternative embodiments, the abutment surface is further provided with a buffer member for abutting the flip plate.

[0017] The buffer component can absorb some of the impact energy when the flip plate closes, thus playing a buffering role. This helps to reduce noise and hard collisions between components, improves operational stability, and extends the service life of the mechanism.

[0018] In some alternative embodiments, the sensor is a magnetic sensor, and the guide portion has a fixing groove on the side facing the magnetic sensor. A magnet is provided in the fixing groove, and the magnet cooperates with the magnetic sensor to sense the position of the guide portion.

[0019] Using magnetic induction, the position of the guide part is determined by non-contact detection of the magnetic signal. It has the characteristics of strong anti-interference ability and long service life, which helps to improve the reliability and durability of detection.

[0020] In some alternative embodiments, the buffer is a spring, with a mounting hole on the abutting surface, the spring being located inside the mounting hole and partially extending out.

[0021] When the flip plate closes, the spring first abuts against the flip plate, and then a certain pressure is applied to make the supporting surface support the flip plate. In this way, the impact of the flip plate on the supporting surface can be reduced by the spring, which helps to reduce noise and vibration.

[0022] In some alternative embodiments, the buffer is an elastic soft membrane attached to the supporting surface.

[0023] The elastic membrane can absorb some of the impact energy when the flip-top closes, which helps to reduce noise and vibration.

[0024] It employs a light sensor to perform non-contact detection by controlling the continuity of light paths. This eliminates mechanical wear, provides a fast response, and helps improve the system's response speed and long-term stability. Simple Explanation of the Diagram

[0029] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and embodiments, is provided. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0031] Because the springs themselves are small and the side buttons may be densely packed, manual installation can easily result in the springs not fully engaging with the buttons, misalignment, or improper installation. These factors can all lead to poor button feel and even affect the normal functioning of the buttons.

[0032] This application provides a spring clip mounting mechanism, including a carrier plate, a positioning fixture, a clamping post, and a locking assembly. The carrier plate has a support platform for supporting a product. The positioning fixture is located on the carrier plate and above the support platform, and has a vertically extending guide groove. A sensor is located on the inner wall of the guide groove. The clamping post is located on the side of the positioning fixture away from the support platform, and is configured to partially pass through the guide groove and extend to the upper surface of the support platform to press the spring clip of the product. The locking assembly is signal-connected to the sensor. When the clamping post is not inserted into the guide groove, the locking assembly locks the position of the positioning fixture relative to the carrier plate. When the clamping post is inserted into the guide groove and triggers the sensor, the locking assembly unlocks the position of the positioning fixture relative to the carrier plate.

[0033] By using sensors to detect whether the clamping pin is accurately inserted into the guide slot, and linking the locking components to control the locking and unlocking of the positioning fixture, this design ensures that the subsequent product removal operation is only allowed after the clamping pin is accurately aligned. This improves the alignment accuracy and process reliability of the spring installation and reduces installation quality problems caused by inaccurate positioning.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0035] Please refer to Figures 1 and 2. One embodiment of this application provides a spring mounting mechanism 001, including a carrier plate 100, a positioning fixture 200, a fastening post 300, and a locking component 400. The positioning fixture 200, the fastening post 300, and the locking component 400 are all located above the carrier plate 100.

[0036] The carrier plate 100 is provided with a support platform 110, which is used to support a product (not shown). In this embodiment, the support platform 110 is used to support the frame of a mobile phone. In other embodiments, the support platform 110 is used to support the frame of other mobile terminal devices such as tablet computers.

[0037] The positioning fixture 200 is disposed on the carrier plate 100 and located above the support platform 110. The positioning fixture 200 is provided with a guide groove 210 that runs vertically through the product. A sensor 220 is provided on the inner side wall of the guide groove 210. The guide groove 210 faces the position of the spring to be installed on the product.

[0038] The clamping post 300 is located on the side of the positioning fixture 200 away from the support platform 110. The clamping post 300 is configured to partially pass through the guide groove 210 and extend to the upper surface of the support platform 110 to clamp the spring sheet of the product. The locking component 400 is signal-connected to the sensor 220. When the clamping post 300 is not inserted into the guide groove 210, the locking component 400 locks the position of the positioning fixture 200 relative to the carrier plate 100. When the clamping post 300 is inserted into the guide groove 210 and triggers the sensor 220, the locking component 400 unlocks the position of the positioning fixture 200 relative to the carrier plate 100.

[0039] By using sensor 220 to detect whether the fastening post 300 is accurately inserted into guide groove 210, and linking locking component 400 to control the locking and unlocking of positioning fixture 200, this design ensures that subsequent product removal operations are only allowed after the fastening post 300 is accurately aligned, thereby improving the alignment accuracy and process reliability of spring installation and reducing installation quality problems caused by inaccurate positioning.

[0040] In some embodiments, the end of the clamping column 300 furthest from the support platform 110 is connected to the robotic arm. In other embodiments, the end of the clamping column 300 furthest from the support platform 110 is connected to a multi-axis mobile platform, which may be a three-axis, four-axis, or five-axis mobile platform.

[0041] In some embodiments, the spring mounting mechanism 001 further includes a flip plate 500, which is located above the support platform 110. One side of the flip plate 500 is hinged to the carrier plate 100, and a locking component 400 locks or unlocks the other side of the flip plate 500. A positioning fixture 200 is fixed to the side of the flip plate 500 away from the support platform 110. The flip plate 500 allows the positioning fixture 200 to rotate around the hinge axis, thereby opening up the operating space, facilitating the placement and removal of the product and the observation and adjustment of the installation process, thus improving the ergonomics and convenience of operation.

[0042] In some embodiments, multiple positioning fixtures 200 are provided, and the multiple positioning fixtures 200 are spaced apart from the flip plate 500 and move synchronously with the flip plate 500. By providing multiple positioning fixtures 200, multiple installation stations of the product can be simultaneously addressed, and multiple spring pieces can be installed synchronously or sequentially, which significantly improves the efficiency of mass production.

[0043] In some embodiments, the locking assembly 400 includes a mounting base 410, a drive member 420, and a locking head 430. The mounting base 410 is fixed to the carrier plate 100 and has a bearing surface 411 for supporting the lower surface of the flip plate 500, thereby providing support for the flip plate 500.

[0044] The drive unit 420 is located on the mounting base 410 and has a drive end (not shown). The locking head 430 is connected to the drive end, so as to have a locked state in which the flip plate 500 is extended and blocked, and an unlocked state in which the flip plate 500 is retracted and released from blocking. The drive unit 420 controls the locking head 430 to achieve precise locking and unlocking actions, which helps to improve the rigidity and stability of the mechanism in the working state.

[0045] In some embodiments, the drive element 420 is a drive cylinder. In other embodiments, the drive element 420 can be a hydraulic cylinder, a linear motor, or other types of drive components.

[0046] In some embodiments, the abutment surface 411 is provided with a positioning boss 412, and the flip plate 500 is provided with a positioning groove 510, which engages with the positioning boss 412. The engagement between the positioning boss 412 and the positioning groove 510 provides precise positioning when the flip plate 500 closes, reduces possible deviations in the closed position, and improves the repeatability of the positioning fixture 200 relative to the carrier plate 100.

[0047] In some embodiments, the abutment surface 411 is also provided with a buffer (not shown), which is used to abut the flip plate 500. The buffer can absorb part of the impact energy when the flip plate 500 closes, thus playing a buffering role, which helps to reduce noise and hard collisions between components, improve operational stability and extend the service life of the mechanism.

[0048] In some embodiments, the buffer is a spring, and the abutment surface 411 is provided with a mounting hole. The spring is located in the mounting hole and partially extends out, so that when the flip plate 500 is closed, the spring first abuts against the flip plate 500, and then the abutment surface 411 supports the flip plate 500 by a certain pressure.

[0049] In other embodiments, the buffer is an elastic soft membrane attached to the abutment surface 411 so that it absorbs part of the impact energy when the flip plate 500 closes, thus playing a buffering role.

[0050] Referring to Figures 1 and 3, in some embodiments, the clamping post 300 includes a main body 310, a guide portion 320, and a clamping portion 330. The guide portion 320 connects the main body 310 and the clamping portion 330. The main body 310 is used to connect a robotic arm for easy automated control. The guide portion 320 cooperates with the guide groove 210 to trigger the sensor 220, ensuring accurate motion trajectory for reliable sensor 220 triggering. The clamping portion 330 passes through the guide groove 210 and extends to the upper surface of the support platform 110 to clamp the spring clips of the product. This structural division of labor helps improve the stability and force control of the installation action, enhancing the consistency of the installation effect.

[0051] Referring to Figures 3 and 4, in some embodiments, the sensor 220 is a magnetic sensor 220. A fixing groove 321 is provided on the side of the guide portion 320 facing the magnetic sensor 220. A magnet 322 is disposed within the fixing groove 321. The magnet 322 cooperates with the magnetic sensor 220 to sense the position of the guide portion 320. Employing magnetic induction, the position of the guide portion 320 is determined by non-contact detection of the magnet 322 signal. This method features strong anti-interference capability and a long service life, contributing to improved reliability and durability of the detection.

[0052] In some embodiments, the positioning fixture 200 has a mounting groove 230 on its side, wherein the mounting groove 230 is connected to the guide groove 210, and the magnetic sensor 220 is mounted in the mounting groove 230, which helps to improve the positional stability of the magnetic sensor 220.

[0053] In some embodiments, the sensor 220 is a pressure sensor 220. When the guide portion 320 extends into the guide groove 210, the guide portion 320 presses against the pressure sensor 220 to sense the position of the guide portion 320. Using the pressure sensor 220, the signal is triggered by direct physical contact pressure, resulting in a direct response and simple judgment logic, which helps to improve the accuracy and timeliness of detection.

[0054] In some embodiments, the sensor 220 is a light sensor 220. The light emitted by the light sensor 220 is located in the movement path of the guide portion 320. When the guide portion 320 extends into the guide groove 210, the guide portion 320 blocks the light emitted by the light sensor 220 to sense the position state of the guide portion 320. Using the light sensor 220, non-contact detection is performed by controlling the continuity of the light path. This eliminates mechanical wear, provides a fast response, and helps improve the system's response speed and long-term stability.
