Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of locking equipment, in particular to a screw locking device with depth control and detection function. BACKGROUND

[0002] Screw locking is an indispensable basic link in modern industrial manufacturing, and is widely used in automatic production lines of electronic products, automobile parts, household appliances, etc. In order to improve efficiency and quality, automatic screw locking equipment has emerged, and is developing towards high precision, high flexibility and high intelligence. However, even if advanced locking equipment is used, a series of technical problems caused by the limitations of workpiece fixing methods, locking environment and quality detection methods are still faced in the production process, which directly affects the reliability and qualification rate of the final product.

[0003] When the existing equipment performs locking action, its positioning system and workpiece clamping system are often separated or not precisely cooperative. The driving head rotates at high speed to apply torque, and this process will generate force on the workpiece. If the workpiece cannot be firmly and accurately fixed at the locking point, the instantaneous impact and vibration will cause the workpiece to produce a small displacement. This displacement directly causes the screw to tilt into the hole, damage the screw thread, and even scratch the workpiece surface, resulting in locking failure. In addition, as product design becomes increasingly complex, workpiece surfaces vary, including curved surfaces, thin walls or fragile materials. The general clamps matched with traditional locking equipment are rigid structures, lack of adaptability, and when clamping such special workpieces, the contact pressure is difficult to control, and permanent pressure marks, scratches or structural damage are easily caused. At the same time, dust, debris and other small foreign matters in the production environment may fall into the screw hole to be locked, and the existing equipment lacks a pre-processing link, resulting in the screw being unable to be tightened in place, causing false locking.

[0004] In production practice, a certain proportion of defective screws are inevitable, and if the unqualified screws are operated on the products on the production line by the screw locking equipment, it may cause the screw to be locked skew, the toothless screw to be locked empty, and the false locking, etc. These screws with quality problems will cause quality risks to the product workpiece (such as a circuit board) in the locking process, making the quality of the processed products unstable, and even causing the scrap of the circuit board workpiece.

[0023] Specifically, the device gives the moving plate 3 the ability of fast and accurate movement in three-dimensional space through the three-axis guide rail 2, and the visual guiding assembly 9 is used for intelligent visual addressing, so that the automatic accurate focusing on any screw hole position on the complex workpiece is realized; before locking, the clamping finger 509 of the fixing assembly 5 stably clamps the workpiece under the protection of the gasket 510, so that the micro displacement of the workpiece caused by the reaction force in the locking process is prevented, and the auxiliary assembly 6 synchronously blows and purifies the target screw hole, so that the hidden troubles of false locking or floating locking caused by foreign matters are eliminated from the source; the motor 403 of the rotary driving assembly 4 provides controllable torque, the pneumatic cylinder 402 controls the downstroke and depth of the chuck 404, and meanwhile the chuck 404 is constrained by the guide cylinder 504, so that the absolutely vertical locking posture is ensured, and the screw inclination or thread damage is effectively prevented.

[0024] Please refer to the accompanying drawings Figure 6 - the accompanying drawings Figure 7The auxiliary assembly 6 comprises a fixed block 601, the upper surface of the fixed block 601 is fixed to the lower surface of the shell 502, the lower surface of the fixed block 601 is fixed with an air bag 602, the two sides of the air bag 602 are penetrated by air ducts 603, the end of the air duct 603 is fixed with a nozzle one 604, the nozzle one 604 is arranged below the clamping finger 509, the outer wall of the rotating rod 508 is fixed with a plurality of cams 605, the cam 605 is arranged in the inside of the shell 502, the outer wall of the cam 605 is arranged above the air bag 602.

[0025] Specifically, when the rotating rod 508 used for clamping the workpiece rotates, the cam 605 integrated thereon will accurately extrude the air bag 602. This purely mechanical driving mode instantaneously converts the gas in the air bag 602 into a high-pressure pulse airflow through the air duct 603, and accurately sprays it to the target screw hole area by the nozzle one 604.

[0026] Please refer to the accompanying drawings Figure 8 - the accompanying drawings Figure 9 The vibration assembly 7 comprises a support plate one 701, the outer wall of the support plate one 701 is fixed to the outer wall of the fixed seat 401, the inside of the support plate one 701 is fixed with a hydraulic rod one 702, the driving end of the hydraulic rod one 702 is fixed with a piezoelectric ceramic exciter 703, the detection assembly 8 comprises a support plate two 801, the outer wall of the support plate two 801 is fixed to the outer wall of the fixed seat 401, the inside of the support plate two 801 is fixed with a hydraulic rod two 802, the driving end of the hydraulic rod two 802 is fixed with a fixed ring 803, the inside of the fixed ring 803 is fixed with a plurality of microphones 804, the microphone 804 annular array is outside the batch head 404, the upper surface of the fixed ring 803 is fixed with a processor 10, and the processor 10 and the microphone 804 are electrically connected.

[0027] Specifically, after the screw locking is completed, the piezoelectric ceramic exciter 703 driven by the hydraulic rod 1 702 applies precise control of high-frequency vibration energy to the screw head as an excitation signal, so as to excite the inherent resonance response of the entire fastening connection body, at the same time, the microphone 804 array on the fixed ring 803 is deployed to the optimal sound field receiving position by the hydraulic rod 2 802, so as to synchronously capture the weak acoustic frequency spectrum and time domain decay characteristics generated by the response from multiple dimensions; the high-dimensional data collected is analyzed by the processor 10 in real time, and by comparing with the acoustic fingerprints of standard qualified parts in the database, the resonance frequency deviation and damping change caused by thread slip, locking floating or substrate microcrack can be extremely sensitively distinguished, so that direct and quantitative evaluation of fastening quality is realized.

[0028] Please refer to the accompanying drawings Figure 8 -attached drawings Figure 9 The visual guidance assembly 9 comprises a mounting block 2 901, the outer wall of the mounting block 2 901 is fixed on the outer wall of the fixed seat 401, the outer wall of the mounting block 2 901 is fixedly connected with a connecting block 1 902, the inner part of the connecting block 1 902 is fixedly connected with a camera probe 903, the lower part of the camera probe 903 is provided with a magnetic ring 905, the outer wall of the magnetic ring 905 is attached with an electromagnet 904, the outer wall of the electromagnet 904 is fixed on the outer wall of the supporting plate 2 801, the upper surface of the magnetic ring 905 is fixedly connected with a miniature air pump 906, the driving end of the miniature air pump 906 is fixedly connected with an exhaust pipe 907, the end of the exhaust pipe 907 is fixedly connected with a flow divider 908, a plurality of nozzles 2 909 are penetrated through the outer side of the flow divider 908, the outer wall of the flow divider 908 is fixedly connected with a connecting block 2 910, the lower surface of the connecting block 2 910 is fixed on the upper surface of the magnetic ring 905, the outer wall of the fixed seat 401 is fixedly connected with a controller 1 1, and the controller 1 1 and the camera probe 903 are electrically connected.

[0029] Specifically, the core component camera probe 903 driven by the controller 1 1 can realize sub-millimeter level accurate positioning guidance through advanced image recognition algorithm for high-speed scanning and feature point matching of workpieces, so as to give the whole device the flexible production capacity of adapting to different workpieces and different cloth arrangement modes; the ingenious part of the assembly is its active environment protection system, in which the miniature air pump 906 can periodically spray high-pressure pulse airflow from the multiple nozzles 2 909 through the exhaust pipe 907 and the flow divider 908, form a gas curtain barrier, and actively blow off the dust attached to the surface of the optical lens, so as to ensure the visual clarity and positioning accuracy under long-term operation; more importantly, the electromagnet 904 and the magnetic ring 905 work cooperatively to generate a controllable magnetic field trap in the key area, which is used to actively capture and adsorb the tiny metal debris generated in the production process, so as to prevent these conductive pollutants from causing permanent scratches on the lens or short circuit risk on the circuit board.

[0030] Working principle: First, the controller 11 receives instructions, activates the visual guidance component 9, the inside of the camera probe 903 takes pictures of the workpiece to identify the screw hole, the controller 11 drives the three-axis guide rail 2 according to the image data, so that the moving plate 3 drives the entire functional head to move to the target point directly above; Then, the fixed component 5 starts to work, the electric push rod 505 drives the rack 506, the rack 506 engages the gear 507 to make the left and right two rotating rods 508 rotate towards each other, thereby driving the lower clamping fingers 509 to clamp the workpiece, the gasket 510 at the bottom end can avoid damaging the surface of the workpiece, while the rotating rods 508 are rotating, the cam 605 on the outer wall will squeeze the air bag 602 in the auxiliary component 6, so that air is sprayed out from the nozzle one 604 through the air guide pipe 603, and the screw hole about to be locked is cleaned by air; After positioning and cleaning, the air cylinder 402 in the rotary drive component 4 pushes down, so that the motor 403 drives the chuck 404 to descend and tighten the screw through the precise guidance of the guide cylinder 504; After locking, the key detection stage is entered, the hydraulic rod one 702 of the vibration component 7 is extended, so that the piezoelectric ceramic exciter 703 at the top end contacts the screw head and applies excitation with a specific high-frequency signal (such as 32 kHz) to make it resonate, at the same time, the hydraulic rod two 802 of the detection component 8 is also extended synchronously, the microphone 804 ring array on the fixed ring 803 is deployed around the screw, which is used to collect the acoustic response signals generated by resonance; these signals are transmitted to the processor 10, the processor 10 accurately calculates the locking depth and actual tightening state of the screw by analyzing the phase difference and sound wave flight time of each microphone 804 signal, and combining the Doppler effect compensation algorithm, so as to effectively identify hidden defects such as loose, floating lock or substrate cracking; Finally, during the detection interval or when needed, the miniature air pump 906 in the visual guidance component 9 will spray clean air flow from the nozzle two 909 through the exhaust pipe 907 and the flow divider 908, to remove contaminants on the surface of the camera probe 903 or the microphone 804, ensuring long-term detection accuracy, while the electromagnet 904 and the magnetic ring 905 cooperate to assist the precise positioning or adsorption of metal dust of the cleaning module, and finally the entire device completes a closed-loop locking operation with high precision and depth detection under the support of the bracket 1.

[0031] The core formula of the Doppler effect compensation algorithm is as follows: In the formula: f e : the compensated emission frequency (Hz), the original vibration frequency of the sound source (screw head) actually emitted without the influence of Doppler frequency shift calculated by the algorithm; f m: apparent frequency (Hz) measured by the microphone, which is the frequency of the sound wave actually received by the stationary microphone, which has changed due to the movement of the sound source; c: propagation speed of the sound wave in the medium (m / s), which is a known physical quantity, in this scenario, it usually refers to the speed of sound in air (about 343 m / s), which is affected by environmental factors such as temperature, humidity, etc.; v s : locking speed of the sound source (screw head) (m / s), which refers to the speed of the screw head moving along the axis direction towards the microphone, and the value is positive, which is provided by the servo motor encoder or controller of the device in real time.
