Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and in particular to a telescopic wire with electronic sound generation and its processing equipment. Background Technology

[0002] In devices requiring acoustic or electrical stepped feedback, a common technique involves arranging multiple electrical contacts with specific height differences on a substrate. For example, some encoders or position sensors use multiple stepped metal contacts that sequentially contact each other via a sliding or rotating brush, generating signals representing different positions. The core of this approach lies in the precise manufacturing and installation of the absolute heights of the contacts and their relative height differences. Any minute deviation will directly lead to errors in the output signals (such as sound, resistance, and level), causing the core function to fail.

[0003] However, in existing manufacturing processes, achieving efficient and consistent assembly and welding of these miniature, precise, and stepped contact points presents a significant challenge. Traditional methods typically rely on manual welding (such as soldering), the quality of which is highly dependent on the operator's skills and condition, resulting in poor weld consistency, extremely low efficiency, and high dependence on operator skills, making it difficult to guarantee the consistency of batch products. Even when using automated equipment, the lack of dedicated detection and closed-loop correction mechanisms for the critical dimension of "height sequence" often means that while contacts can be welded, the final stepped height cannot be guaranteed to meet stringent acoustic or electrical models. Furthermore, the contact roots lack effective protection after conventional welding, making them susceptible to performance degradation due to corrosion and stress during dynamic use.

[0004] Therefore, designing a specialized processing method and equipment that can automatically, accurately, and reliably achieve stepped contact positioning, welding, and integrated sealing has become a technological bottleneck in realizing such high-performance products. Summary of the Invention

[0005] This invention provides a retractable cable with electronic sound generation and its processing equipment, which can solve the problem that existing technologies rely on manual welding (such as soldering iron welding), the quality of which is highly dependent on the operator's skills and condition, resulting in poor weld consistency, extremely low efficiency, and difficulty in ensuring the consistency of batch products.

[0028] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0029] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a retractable cord with electronic sound generation, comprising: a retractable cord body 7, a rotating generating disk 72, and a contact base plate 21. A retractable cord 71 is installed inside the retractable cord body 7. The rotating generating disk 72 and the contact base plate 21 are both installed inside the retractable cord body 7. The rotating generating disk 72 is disposed on the upper side of the contact base plate 21. A plurality of abutment guide plates 22 are disposed on the contact base plate 21. An elastic connecting piece 73 is installed at the bottom end of the rotating generating disk 72. When the retractable cord 71 is pulled out, it can synchronously drive the rotating generating disk 72 to rotate, so that its elastic connecting piece 73 can abut against the plurality of abutment guide plates 22.

[0030] Multiple welding grooves 23 are provided on the contact base plate 21, and the abutment guide plate 22 is installed in the welding groove 23.

[0031] The abutting guide plate 22 includes a welding frame and a metal sheet. The welding frame is installed on the outer end of the metal sheet, and an elastic metal rod is installed at the bottom end of the welding frame. A molten protective layer is installed around the elastic metal rod.

[0032] The core function of the telescopic cord with electronic sound provided in this embodiment of the invention is to directly convert the linear telescopic movement of the telescopic cord 71 into a layered electronic sound effect with distance indication.

[0033] When the user pulls the telescopic cable 71 outward, the linear motion of the telescopic cable 71 synchronously drives the rotating disk 72 to rotate through the internal transmission mechanism, and the elastic connecting piece 73 fixed to the bottom of the rotating disk 72 then makes a circular motion above the contact base plate 21.

[0034] The multiple contact guide plates 22 arranged on the contact base plate 21 are not on the same plane, but are preset to have progressively increasing heights.

[0035] Therefore, as the rotation angle of the rotating disk 72 increases corresponding to the increased extension length of the telescopic line 71, the elastic connecting piece 73 will sequentially contact and separate from the abutment guide piece 22 at different heights. Each contact generates an electrical pulse signal.

[0036] The signal can drive a simple sound-generating circuit, such as a buzzer, to produce sound. Since the contact guide plate 22 is arranged in a circle with a fixed height difference, and the rotation of the rotating generating disk 72 and the pulling out of the telescopic line 71 are continuous and synchronous.

[0037] Its acoustic feedback logic is not a simple single-loop cycle. When the telescopic cable 71 is continuously pulled out and the rotating disk 72 goes beyond the first loop to enter the second loop and even the subsequent loops, the elastic connecting piece 73 will pass through all the abutting guide pieces 22 again with the same height sequence. Therefore, the sound pattern heard by the user is progressively increasing.

[0038] For example, the sound sequence of the first round is tone A-tone B-tone C, while the beginning of the second round, when the lowest point is touched again, is uttered with tone D, which represents a longer duration, and the sequence continues to progress linearly.

[0039] The above method achieves hierarchical and cumulative intuitive distance feedback. Users can not only perceive the relative extension progress of the telescopic line 71 through the pitch change within the current cycle, but also judge the approximate total extension length of the telescopic line 71 by recognizing how many times a certain reference tone has been heard. This achieves a practical human-computer interaction function that goes beyond simple prompts and is rich in information.

[0040] The abutment guide plate 22 adopts a split design, consisting of a metal plate responsible for contacting the elastic connecting plate 73 and a welding frame for welding and fixing.

[0041] The elastic metal rod is covered with a solid fusible protective layer. During the final assembly welding, the welding heat of the welding frame and the welding groove 23 on the contact base plate 21 will melt this protective layer. The molten material flows into and fills the bottom of the welding groove 23. After cooling, it forms an insulating seal to prevent the risk of electrochemical corrosion and increased contact resistance caused by moisture and sweat intrusion.

[0042] like Figures 5 to 7 As shown, a telescopic wire processing device with electronic sound generation includes: a telescopic wire processing device, which is used to weld a contact base plate 21 to multiple abutment guide pieces 22, and the telescopic wire processing device includes: a transmission table 2 and a processing table 1. The transmission table 2 is used to transmit multiple contact base plates 21; a driving component is installed on the processing table 1, and the processing table 1 is connected to the transmission table 2. A positioning welding component 3 is installed at the output end of the driving component. The positioning welding component 3 is used to fix multiple abutment guide pieces 22 in a sequentially increasing order in the welding groove 23, thereby completing the welding of multiple abutment guide pieces 22.

[0043] The drive assembly includes a drive column 11, the bottom end of which is connected to the top of the processing table 1. An electric push rod is installed at the bottom end of the drive column 11, and the output end of the electric push rod is connected to the positioning and welding assembly 3. The positioning and welding assembly 3 includes a positioning ring 4, a feedback ring 5, and a welding ring 6. A support column is installed in the middle of the positioning ring 4, and the bottom surface of the positioning ring 4 is inclined.

[0044] Multiple evenly distributed electric push rods 41 are installed at the bottom of the positioning ring 4. A vacuum adsorption tube 42 is installed at the output end of the electric push rod 41, and the vacuum adsorption tube 42 is matched with the welding groove 23.

[0045] Among them, the drive assembly and positioning ring 4 system is the core actuator for achieving precise positioning and welding of multiple abutment guide plates 22. Its design principle and beneficial effects are as follows:

[0046] The drive assembly of the system is supported by the drive column 11, with its bottom fixed to the processing table 1. The electric push rod installed at the top is responsible for driving the entire positioning and welding assembly 3 to move vertically up and down, and provides stable and controllable axial feed power for subsequent precise positioning and welding operations.

[0047] The positioning ring 4 in the positioning welding assembly 3 is characterized by having its bottom surface set as an inclined plane, which creates a height difference between the initial spatial positions of the multiple electric push rods 41 and the vacuum adsorption tube 42 installed at its bottom end.

[0048] When the positioning welding assembly 3 is pressed down as a whole, these uniformly distributed vacuum adsorption tubes 42 will simultaneously contact and press into each abutment guide plate 22 in the welding groove 23.

[0049] Due to the effect of the inclined bottom surface, the initial height of the pressure application point of the vacuum adsorption tube 42 is different. Combined with the elastic force provided by the elastic metal rod set at the lower end of the abutment guide plate 22, all abutment guide plates 22 can be synchronously pre-pressed to a pre-set spatial posture that increases sequentially from low to high, thus completing a rapid and consistent preliminary coarse positioning.

[0050] Once completed, the vacuum adsorption tube 42 generates negative pressure to firmly adsorb the contact guide plate 22 in a non-mechanical clamping manner. Each vacuum adsorption tube 42 is connected to an independent electric push rod 41, which allows for independent and precise height adjustment of each contact guide plate 22.

[0051] After subsequent detection by the pressure sensor 52 of the feedback loop 5, if the height of a certain abutting guide plate 22 deviates from the preset acoustic model, the corresponding specific electric push rod 41 can be instructed to extend or retract individually, driving the abutting guide plate 22 to make fine adjustments in height until the height sequence of all abutting guide plates 22 reaches the precise design requirements.

[0052] This integrated design combines three main functions: initial positioning via an inclined surface, precise fixing via vacuum adsorption, and independent fine-tuning via an electric push rod. It replaces the traditional positioning methods that rely on manual labor or complex vision systems with a high degree of automation. The mechanical structure design directly generates a height gradient, which is then combined with electronic control closed-loop feedback for precise correction. This fundamentally ensures the accuracy and consistency of the relative distance between the multiple contact guides 22, thereby guaranteeing the accuracy and stability of the pitch change sequence of the final electronic sound-emitting telescopic cable when it emits sound. At the same time, it significantly improves production efficiency and product yield.

[0053] A connecting frustum 51 is installed in the middle of the feedback loop 5. The connecting frustum 51 is fixedly connected to the support column, and a servo motor is embedded at the bottom of the connecting frustum 51. A miniature electric actuator is installed at the output end of the servo motor, and a pressure sensor 52 is installed at the output end of the miniature electric actuator. The pressure sensor 52 is electrically connected to the electric actuator 41.

[0054] Among them, the feedback loop 5 is a precision closed-loop control unit that performs final calibration and verification of the height sequence of the contact guide plate 22 after the vacuum adsorption fixation has been completed. Its operation is based on the fact that the inclined bottom surface of the positioning ring 4 has been mechanically squeezed to compress the elastic metal rods under each contact guide plate 22, thereby forming a preliminary height gradient.

[0055] The servo motor and the miniature electric actuator first drive the pressure sensor 52 to descend vertically, so that its retractable measuring head contacts and stably presses against the abutment guide plate 22, which is confirmed as the initial lowest point.

[0056] At this point, the system records the pressure sensor reading at this reference point and uses it as the zero point or reference value for subsequent comparisons.

[0057] Subsequently, the servo motor starts, driving the pressure sensor 52 to rotate horizontally. The retractable measuring head of the pressure sensor 52 will pass over the top of each of the other abutting guide plates 22 on the circumference in turn. Since the preset height of each guide plate is different, the amount of compression when the measuring head contacts them is also different, thus generating different pressure readings in real time.

[0058] The control system continuously reads the pressure values ​​during the rotational scanning process. These pressure values ​​are not used to infer the absolute height, but are directly compared with a preset pressure threshold range corresponding to the "qualified height range".

[0059] If the pressure reading corresponding to a certain abutment guide plate 22 falls within the preset range, its height is deemed to be qualified; if the reading deviates from the range, it is determined that the height of that point needs to be adjusted, and the abnormal point will be locked immediately. After the scanning cycle ends or through communication, the electric push rod 41 of the corresponding point will be controlled to extend and retract slightly, thereby adjusting the height of the abutment guide plate 22 fixed by the vacuum adsorption tube 42. This process can be iterated until the pressure readings of all points meet the requirements.

[0060] The presence of the elastic metal rod is crucial, as it provides the necessary and controllable rebound force during the initial positioning stage, enabling simple mechanical compression to form a preliminary and stable height gradient, thus creating conditions for subsequent vacuum adsorption fixation and precision detection. The retractable measuring head of the pressure sensor is adapted to the working conditions of rotating scanning on the fixed part, avoiding jamming or interference.

[0061] In summary, this feedback loop 5 works in deep collaboration with the previous positioning steps to ensure that the entire processing equipment meets the acoustic accuracy requirements—a core intelligent element.

[0062] The top of the welding ring 6 is connected to the feedback ring 5 via multiple connecting rods, and 61 is embedded inside the welding ring 6. An electric slider 62 is slidably connected inside the 61, and a micro welding robot 63 is installed on the top of the electric slider 62.

[0063] Among them, the welding ring 6 is the functional module in the positioning welding assembly 3 that ultimately performs the connection task. Its design realizes automated and flexible welding operations.

[0064] The welding ring 6 is rigidly connected to the feedback ring 5 above it through multiple connecting rods. This structure ensures that the welding ring 6, the feedback ring 5 which has completed the height detection and calibration, and the positioning ring 4 always maintain precise concentricity and fixed relative position.

[0065] Once the pressure sensor 52 of the feedback loop 5 confirms the final precise position of all the contact guide plates 22, the welding work is then carried out through the welding ring 6.

[0066] The core actuator for welding operations is integrated inside the welding ring 6. The annular electric slide rail 61 embedded inside it forms a continuous circular motion path. The electric slider 62 is slidably connected inside the slide rail and is driven by a precision motor. It can perform circumferential motion with high repeatability and positioning accuracy along the slide rail. The micro welding manipulator 63 mounted on the top of the electric slider 62 integrates welding energy generation devices such as micro laser heads or resistance welding electrodes and their control systems.

[0067] Once the positioning and feedback process is complete, the entire positioning welding assembly 3 can be slightly raised or held in position to make room for the welding ring 6. The control system drives the electric slider 62 to carry the micro welding robot 63 along the slide rail 61 according to the program, and stops precisely above each welding frame that abuts the guide plate 22.

[0068] Subsequently, the micro welding robot 63 performs micro-movements in the vertical direction and starts the welding program, such as emitting a laser or energizing the device. In conjunction with the vacuum adsorption tube 42, it fixes the contact guide plate 22 and completes the welding of the connection point between the welding frame and the contact base plate 21.

[0069] Since all the contact guide plates 22 are precisely distributed in a circular pattern and height sequence according to the acoustic model requirements, the welding robot 63 only needs to operate according to the preset program sequence, without the need for repositioning, which greatly improves efficiency and consistency.

[0070] It should be noted that when the welding ring 6 performs welding, the local high temperature generated by the micro welding robot 63, for example, the temperature of the micro laser welding point can reach above 800°C or the resistance welding temperature is around 600°C, is conducted to the elastic metal rod through the welding frame while the welding frame is being connected.

[0071] The material of the fusible protective layer on the elastic metal rod can preferably be a special polyamide (PA) or thermoplastic polyurethane (TPU) material with a melting point between 180°C and 220°C, and can be compounded with micron-sized ceramic fillers to adjust its flowability and final insulation strength.

[0072] The material's transition temperature is set significantly lower than the weld heat-affected zone temperature but much higher than the product's daily operating temperature, ensuring that the phase transition is reliably triggered only during welding.

[0073] Upon heating, the protective layer rapidly melts into a low-viscosity liquid to ensure smooth downward flow along the surface of the elastic metal rod under gravity and capillary action. The liquid material completely fills the bottom space of the weld groove 23, which is enclosed by the elastic metal rod, the metal bottom end of the guide plate 22, and the inner side of the weld. Subsequently, the material cools naturally and solidifies again.

[0074] Its volume shrinkage rate after curing is usually designed to be less than 2% to avoid internal stress or peeling.

[0075] During product use, the repeated pulling of the telescopic cord will cause the rotating disk 72 and its bottom elastic connecting piece 73 to have continuous dynamic contact and friction with multiple abutting guide pieces 22. This action itself will disturb the internal space, making it easy for pollutants such as moisture, dust and human sweat in the environment to enter the welding tank 23.

[0076] If there are microscopic metal bonding defects inside the solder joint of the contacting guide piece 22, these invading contaminants will form electrolytic corrosion channels along the defects, causing interface corrosion, slow increase and instability of contact resistance. The direct consequence is that the electrical contact signal generated when the elastic connecting piece 73 passes by will be mixed with noise and become intermittent, ultimately causing the prompt sound emitted by the product to be distorted, pitched or malfunctioning, and the core acoustic prompt function will be lost.

[0077] The synchronous process integrated in this design uses the high-temperature residual heat generated during welding as a controllable heat source to trigger an in-situ phase change and melt flow of the special protective layer material surrounding the elastic metal rod. The molten material actively penetrates and fills the micro-defects on the inside of the weld and the interface of the solder metal through capillary action, and after solidification, it forms a dense insulating sealing layer that is integrated with the structure.

[0078] Therefore, the core function of this sealing layer is to ensure that the electrical connection between each contact guide 22 and the chassis remains stable during long-term repeated use, thereby ensuring the accuracy and stability of the electronic sound signal throughout the entire product life cycle.

[0079] Ultimately, this modular design ensures that welding can be performed with the highest positional accuracy and efficiency after complex height calibration, thus reliably solidifying the acoustic design into a physical product and guaranteeing the consistency and stability of the final electronic sound generation function.

[0080] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
