Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, specifically to a welding machine for the ear mesh of a wireless Bluetooth headset. Background Technology

[0002] With the rapid development of science and technology and the continuous improvement of people's requirements for quality of life, wireless Bluetooth headsets have been widely used. Many people have the habit of listening to music while sleeping, usually by setting a timer or letting it play freely. Music before bed can help them fall asleep quickly, and it does indeed have a good effect. Bluetooth headsets apply Bluetooth technology to hands-free headsets, allowing users to be free from the shackles of annoying wires and easily make calls in various ways. Since its advent, Bluetooth headsets have been a great tool for mobile business professionals to improve efficiency. During the headset manufacturing process, a steel mesh needs to be welded to the headset. However, in the conventional welding process between the steel mesh and the shell, the manufacturer usually needs to manually position and stack the steel mesh on the shell. This not only increases the labor intensity of the manufacturer but also easily leads to problems such as misalignment of the steel mesh or weak welding, greatly affecting the subsequent use of the headset.

The guide mounting groove has a guide rail parallel to the slide rail, and each slide groove has a clamping block connected to the guide rail. Each clamping block has a compression spring on both sides that presses against the side wall of the slide groove. Two pusher cylinders push the corresponding slide seat to move the clamping blocks closer to each other, so that the two clamping blocks clamp and push the material into the corresponding positioning hole. Due to the action of the compression spring, the material is not deformed.

[0015] The material level detection component includes a sliding cylinder and a support plate located at the output end of the sliding cylinder. The support plate has several through holes, and each through hole is equipped with a sensor for sensing the material.

[0016] Preferably, the welding mechanism further includes an adjustment and moving platform, which includes a Y-axis adjustment module and a Z-axis adjustment module. There are two Z-axis adjustment modules, which are respectively mounted on the Y-axis adjustment module and driven by the Y-axis adjustment module to move closer or further apart. The Y-axis adjustment module is equipped with a horizontal guide rail assembly and a bidirectional lead screw. The two Z-axis adjustment modules are slidably mounted on the horizontal guide rail assembly and threadedly connected to the bidirectional lead screw. Y-axis adjustment handwheels are provided at both ends of the bidirectional lead screw.

[0023] Preferably, it also includes a PLC control device.

[0024] The beneficial effects of adopting the above scheme are:

[0025] The wireless Bluetooth headset ear mesh welding machine of this invention automates the assembly and welding of the ear mesh and the shell, greatly improving production efficiency and reducing the labor intensity of producers. Simultaneously, through the setting of multiple calibration components, precise alignment of the mesh and shell is ensured during the assembly process, avoiding problems such as misalignment of the steel mesh or weak welding, thus guaranteeing the subsequent performance of the headset. Through a carefully designed mechanical structure and intelligent control system, an efficient, precise, and reliable production process is achieved.

[0026] In practical implementation, the intermittent conveying mechanism, with its unique drive components, ensures that the turntable rotates precisely at preset time intervals, thereby orderly conveying the assembly fixtures to each workstation. This design not only improves production efficiency but also ensures the smooth operation of each process. The mesh feeding mechanism and the shell feeding mechanism are equipped with efficient mesh storage components and shell storage components, respectively. Through precise calibration components, the mesh and shell can be quickly removed from the storage components and calibrated multiple times to ensure accurate positioning. Then, the first and second four-axis industrial robots respectively transport them to the assembly fixtures. The precise coordination of this series of actions greatly improves the efficiency and accuracy of feeding and assembly.

[0027] As the core component of the entire equipment, the welding mechanism employs a dual-set galvanometer laser welding machine, enabling high-quality welding tasks to be completed in a very short time. Simultaneously, the alignment component pre-presses and aligns the mesh on the assembly fixture before welding to ensure accurate welding positioning. The fume extractor effectively absorbs and treats harmful gases generated during welding, ensuring a clean production environment and protecting worker health.

[0028] The visual inspection unit utilizes high-precision cameras and advanced image processing technology to comprehensively inspect the welded finished products, ensuring that each product meets quality standards. Based on the inspection results from the visual inspection unit, the finished product storage unit uses third- and fourth-axis industrial robots to store qualified or defective products into the corresponding finished product storage components or defective product storage components, achieving automated sorting and storage and further enhancing the intelligence level of the production line.

[0029] Furthermore, the four-axis industrial robots are equipped with buffer and anti-collision components at the material handling end, employing multiple protection designs including a buffer base, movable block, and gripper. This effectively avoids potential collisions and damage during material handling, further enhancing the stability and reliability of the equipment. The linkage and spring design at the top of the movable block ensures smoother gripping and releasing of materials, guaranteeing operational accuracy and safety.

[0030] The ear mesh welding machine for wireless Bluetooth headsets of this invention significantly improves production efficiency and reduces production costs. Furthermore, through precise calibration and welding technology, it ensures product quality and stability. Simultaneously, its remote data acquisition and transmission capabilities greatly facilitate production management, making the production process more transparent and controllable. The advent of this innovative equipment undoubtedly brings revolutionary changes to the field of wireless Bluetooth headset manufacturing, creating enormous economic and social benefits for enterprises.

[0041] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0042] The present invention provides the following preferred embodiments.

[0043] like Figure 1 and Figure 2 As shown, this embodiment provides a wireless Bluetooth headset ear mesh welding machine. The wireless Bluetooth headset ear mesh welding machine includes a cabinet body 10. An intermittent conveying mechanism 20 is provided on the cabinet body 10. Along the conveying direction of the intermittent conveying mechanism 20, a mesh feeding mechanism 30, a shell feeding mechanism 40, a welding mechanism 50, a vision inspection mechanism 60, and a finished product storage mechanism 70 are sequentially arranged and fixed on the cabinet body 10. A PLC control device is provided on the outside of the cabinet body 10 for controlling the operation of the intermittent conveying mechanism 20, the mesh feeding mechanism 30, the shell feeding mechanism 40, the welding mechanism 50, the vision inspection mechanism 60, and the finished product storage mechanism 70.

[0044] Specifically, such as Figure 3 The intermittent conveying mechanism 20 is used to convey materials to each workstation for processing. The intermittent conveying mechanism 20 includes a fixed disc 21, a turntable 22 that moves around the fixed disc 21, and an intermittent drive assembly that drives the turntable 22 to rotate intermittently. The turntable 22 is provided with multiple mounting holes at equal intervals around its circumference. Each mounting hole is provided with a fixed post 23 that is partially exposed outside the turntable 22. An assembly fixture 24 is inserted into two adjacent fixed posts 23.

[0045] In this embodiment, the fixed disk 21 is equipped with a remote I / O module with communication functions (a remote data acquisition and / or transmission module), a power supply, a pneumatic control device, a vacuum control device, and a signal diversity card connected to the remote I / O module. The fixed disk 21 also has a protective cover 25 that encloses the remote I / O module, power supply, pneumatic control device, and vacuum control device. A heat dissipation system 26 is located on the top of the protective cover 25. The remote I / O module, power supply, pneumatic control device, and vacuum control device are signal-connected to the PLC control device. This remote I / O module enables real-time monitoring and data acquisition of the equipment status, ensuring the high efficiency and stability of the welding machine. The power supply provides stable power support for the entire system, ensuring the normal operation of each component. The pneumatic control device is responsible for driving pneumatic components such as cylinders, achieving fast and precise motion control. The vacuum control device is used to generate the necessary vacuum environment during the welding process to ensure welding quality and product performance. The heat dissipation system 26 uses a high-efficiency fan or heat sink design, which can effectively dissipate the heat generated by the components inside the protective cover 25, preventing overheating from damaging the equipment. At the same time, the design of the shield 25 not only protects the internal components from interference and damage from the external environment, but also keeps the equipment clean and aesthetically pleasing.

[0046] The mesh loading mechanism 30 is used to adjust the position of the mesh and place it on the assembly fixture 24. The mesh loading mechanism 30 includes a mesh storage component 31, a mesh calibration component 32, and a mechanism for conveying the mesh from the mesh storage component 31 to the mesh calibration component 32. After the mesh is calibrated twice by the mesh calibration component 32, the mesh is conveyed to the first four-axis industrial robot 33 on the assembly fixture 24. During operation, the mesh storage component 31 moves the tray containing the mesh to below the first four-axis industrial robot 33. After component 31 moves the tray to the set position, the first four-axis industrial robot 33 starts and grabs 5 nets from the tray at once, moving them to the net calibration component 32. After the first four-axis industrial robot 33 and the net calibration component 32 adjust and correct the position of the 5 nets, the first four-axis industrial robot 33 places the 5 nets on the assembly fixture 24. Then, the gap drive component drives the turntable 22 to rotate and transport the assembly fixture 24 containing the nets to the housing loading mechanism 40.

[0047] The housing loading mechanism 40 is used to correct the position of the housing and then transport the housing to the assembly fixture 24 to assemble the mesh and the housing. The housing loading mechanism 40 includes a housing storage component 41, a housing calibration component 42, and a mechanism to transport the housing from the housing storage component 41 to the housing calibration component 42. The housing is then calibrated twice by the housing calibration component 42 before being assembled onto the mesh of the assembly fixture 24 onto the second four-axis industrial robot 43. During operation, the housing storage component 41 moves the tray containing the housing to below the second four-axis industrial robot 43. After the placement component 41 moves the tray to the set position, the second four-axis industrial robot 43 starts and grabs 5 mesh bodies from the tray at once, moving them to the housing calibration component 42. After the second four-axis industrial robot 43 and the housing calibration component 42 adjust and correct the position of the 5 housings, the second four-axis industrial robot 43 places the 5 housings on the assembly fixture 24, assembling the mesh bodies and housings. Then, the gap drive component drives the turntable 22 to rotate and transport the assembly fixture 24 containing the mesh bodies and housings to the welding mechanism 50.

[0048] The welding mechanism 50 is used to weld the assembled mesh and shell together. The welding mechanism 50 includes an adjustable moving platform 51 fixed to the cabinet body 10, a correction component 52 for pre-pressure correction of the mesh, a dual-mirror laser welding machine 53 for welding the mesh and shell together, and a fume purifier 54 for absorbing the gases generated during welding. The adjustable moving platform 51 includes a Y-axis adjustment module 510 and a Z-axis adjustment module 511. Two Z-axis adjustment modules 511 are provided, respectively mounted on the Y-axis adjustment module 510, and driven by the Y-axis adjustment module 510 to move closer or further apart. The Y-axis adjustment module 510 is equipped with a horizontal guide rail. The system includes a horizontal guide rail assembly and a bidirectional lead screw. Two Z-axis adjustment modules 511 are slidably mounted on the horizontal guide rail assembly and threadedly connected to the bidirectional lead screw. Y-axis adjustment handwheels are located at both ends of the bidirectional lead screw. The Z-axis adjustment module 511 has a movable seat slidably connected to the horizontal guide rail assembly. The movable seat has a vertical guide rail assembly and a vertical adjustment lead screw. The galvanometer laser welding machine 53 is slidably mounted on the vertical guide rail assembly and threadedly connected to the vertical adjustment lead screw. A Z-axis adjustment handwheel is located at the top of the vertical adjustment lead screw. The position of the galvanometer laser welding machine 53 is adjusted by the Y-axis adjustment module 510 and the Z-axis adjustment module 511 to ensure accurate alignment of the mesh and the shell during welding. A correction component 52 is used to pre-press and correct the mesh before welding to ensure that the position and shape of the mesh meet welding requirements, thereby improving welding quality. A fume purifier 54 effectively reduces harmful gas emissions during welding by absorbing the gases generated during welding, protecting the health of operators.

[0049] like Figure 4 The dual-galvanometer laser welding machine 53 integrates a vision inspection unit. The two galvanometer laser welding machines 53 are tilted and arranged in a V-shape, with their laser emission areas directly facing the material on the assembly fixture 24. Furthermore, the fume extractor 54's fume extraction pipe is fixed to the cover of the main cabinet 10, extending one end between the two galvanometer laser welding machines 53, allowing it to effectively absorb the exhaust gases generated during welding. This design enables the laser beam to irradiate the material at a specific angle, achieving precise welding of material edges or complex shapes. The vision inspection unit is responsible for real-time monitoring of the welding process, automatically judging omissions and assembly defects to ensure welding accuracy and consistency. This results in a welding efficiency of 1 second per piece and a welding yield of over 99%. The tilted V-shape arrangement of the two galvanometer laser welding machines 53 not only optimizes the welding space layout but also improves welding efficiency. By precisely controlling the direction and angle of the laser beam, this welding machine can flexibly handle materials of different shapes and sizes, achieving high-quality automated welding.

[0050] In addition, in this embodiment, the vision inspection mechanism 60 is fixed on the cover of the main body 10 of the cabinet. The vision inspection mechanism 60 includes a CCD camera and a light source. After the welding mechanism 50 welds the mesh and the shell together, the gap drive component drives the turntable 22 to move the welded assembly to the vision inspection mechanism 60. The vision inspection mechanism 60 takes pictures of the assembly on the assembly fixture 24 and transmits the pictures to the PLC control device. The PLC control device analyzes and judges the pictures. After the PLC control device judges, it feeds back the signal to the finished product storage mechanism 70. The finished product storage mechanism 70 executes the command fed back by the PLC control device and places good products and defective products separately.

[0051] In this embodiment, the finished product storage mechanism 70 is located to the side of the welding mechanism 50. The finished product storage mechanism 70 includes a finished product storage component 71, a defective product storage component 72, and a third or fourth-axis industrial robot 73 that picks up welded finished products or defective products from the assembly fixture 24 and transports them to the finished product storage component 71 or the defective product storage component 72. The third or fourth-axis industrial robot 73 picks up the assembly from the assembly fixture 24 and executes the instructions fed back by the PLC control device to place good products and defective products in the finished product storage component 71 and the defective product storage component 72 in sequence. The defective product storage component 72 includes a placement rack fixed on the cabinet body 10, and a material tray is placed on the placement rack.

[0052] To ensure that the first four-axis industrial robot 33, the second four-axis industrial robot 43, and the third four-axis industrial robot 73 avoid deforming or damaging the product when picking up materials, in this embodiment, as follows: Figure 5The first four-axis industrial robot 33, the second four-axis industrial robot 43, and the third four-axis industrial robot 73 are equipped with buffer anti-collision components 100 at their picking ends. The buffer anti-collision components 100 include a buffer base 101, a movable block 102 slidably mounted on the buffer base 101, and a pneumatic gripper 103 located at the bottom of the movable block 102. Each of the two sliders of the pneumatic gripper 103 is equipped with a clamping block 104, and multiple grippers 105 are arranged on the two clamping blocks 104. One of the clamping blocks 104 is equipped with a proximity sensor. When the proximity sensor detects a contact object, the first four-axis industrial robot 33, the second four-axis industrial robot 43, or the third four-axis industrial robot 73 stops operating. When the pneumatic gripper 103 drives the two clamping blocks 104 to open, the grippers 105 open and clamp the housing. The top of the movable block 102 is equipped with a connecting rod that is connected to the buffer base 101 and fitted with a spring. The spring allows the movable block 102 to buffer against external forces, preventing direct rigid collisions that could damage the product. Furthermore, the design of the buffer anti-collision component 100 also considers the accuracy and stability of material handling. When the proximity sensor detects a contact object and stops the industrial robot's operation, the pneumatic gripper 103 can precisely control the opening degree of the clamping block 104, ensuring that the gripper 105 can firmly clamp the shell, preventing the shell from slipping or being damaged due to improper operation. The application of the buffer anti-collision component 100 greatly improves the automation level and product quality of the entire ear mesh welding machine, making the production of wireless Bluetooth headsets more efficient and reliable.

[0053] The aforementioned mesh calibration component 32 and housing calibration component 42 are used to calibrate the mesh and housing, respectively. They have the same structure, both including a calibration component 320 and a material level judgment component 321 located to the side of the calibration component 320; for example... Figure 6 The calibration component 320 includes a support platform 3201, a positioning fixture 3202 with five positioning holes on the support platform 3201, and pusher components symmetrically arranged on both sides of the positioning fixture 3202 to push materials into the positioning holes; the pusher components include a slide rail disposed on the support platform 3201 and parallel to the positioning fixture 3202, a slide block 3203 slidably mounted on the slide rail, and a pusher cylinder 3204 on the support platform 3201 to drive the slide block 3203 to reciprocate along the slide rail; The positioning fixture 3202 has a guide mounting groove on one end of the slide 3203, and several slide grooves connected to the guide mounting groove are equally spaced on the slide 3203. The guide mounting groove is provided with a guide rail parallel to the slide rail. Each slide groove is provided with a clamping block 3205 connected to the guide rail. Each clamping block 3205 has a compression spring on both sides, one end of which presses against the side wall of the slide groove. The two compression springs can open the clamping block 3205, so that the shell and mesh will not be deformed due to the clamping of the two clamping blocks 3205.

[0054] like Figure 7In addition, the material level judgment component 321 includes a sliding cylinder 3211 and a support plate 3212 located at the output end of the sliding cylinder. The support plate 3212 has five through holes, each containing a sensor for sensing materials. When the first four-axis industrial robot 33 or the second four-axis industrial robot 43 transports the five meshes or shells to the positioning fixture 3202, the two push cylinders 3204 push the corresponding slides 3203 to bring the clamping blocks 3205 closer together, causing the two clamping blocks 3205 to clamp each other and push the material into the corresponding positioning hole. Due to the compression spring... The function is to prevent the material from being deformed by pressure. After the position is corrected, the first four-axis industrial robot 33 or the second four-axis industrial robot 43 transports the five meshes or shells to the support plate 3212, so that the five meshes or shells on the first four-axis industrial robot 33 or the second four-axis industrial robot 43 are aligned with the through holes, so that the sensors can sense the meshes or shells and realize the positioning of the meshes or shells. Then, the five meshes or shells on the first four-axis industrial robot 33 or the second four-axis industrial robot 43 are transported to the assembly fixture 24, thereby making the loading repeatability positioning accuracy ±0.015.

[0055] To prevent the housing and mesh from shifting during welding, a correction component 52 is installed on the side of the adjusting moving platform 51. This correction component 52 presses the housing and mesh firmly onto the assembly fixture 24 so that the dual-galvanometer laser welding machine 53 can weld them. Figure 8 The correction component 52 includes a bracket 520 fixed to the main body 10 of the cabinet. A lifting cylinder 521 is provided on the bracket 520. A horizontal pneumatic slide 522 is provided at the output end of the lifting cylinder 521. A horizontal plate 523 is provided at the output end of the horizontal pneumatic slide 522. A welding groove is provided on the horizontal plate 523 near one end of the assembly fixture 24. Pressure blocks 524 for pressing the material on the assembly fixture 24 are evenly distributed on both sides of the welding groove. The pressure block 524 includes a fixing block embedded in the horizontal plate 523 and an L-shaped connecting block connected to the fixing block. A horizontal pressing plate is provided on the L-shaped connecting block away from the fixing block. The fixing block, the L-shaped connecting block and the horizontal pressing plate are integrated. The horizontal plate 523 is driven to move down by the lifting cylinder 521, so that the horizontal pressing plate presses the shell and the mesh, so as to facilitate welding by the dual-group galvanometer laser welding machine 53. The position of the pressure block 524 is adjusted by the horizontal pneumatic slide 522, so that the pressure block 524 effectively presses the shell.

[0056] In an alternative embodiment, such as Figure 9The assembly fixture 24 includes a positioning frame 240 with five limiting holes, a lifting component 241 for lifting materials in the limiting holes, and a pressure plate drive component 242 mounted on the positioning frame 240 for pressing the materials in the limiting holes. The lifting component 241 is equipped with a push rod for lifting the materials. When the housing is placed in the limiting hole, the pressure plate drive component 242 is activated, fixing the mesh and the housing. During the placement and movement, the mesh and the housing are disengaged from the limiting hole. The lifting component 241 is used to push the welded assembly out of the limiting hole. It should be noted that the pressure plate drive component 242 is equipped with a pneumatic gripper and a lifting cylinder. The two grippers of the pneumatic gripper are equipped with pressure plates, which allows the pressure plates to move horizontally and separate, thus not affecting the feeding and unloading of materials.

[0057] In an alternative embodiment, such as Figure 10 The mesh storage component 31, the housing storage component 41, and the finished product storage component 71 include a moving module 310, a lifting platform 311 located at the output end of the moving module 310, and a tray storage bin 312 located at one end of the moving module 310 and driven by the moving module 310 to receive trays. The tray storage bin 312 includes an empty tray storage bin and a full tray storage bin. The moving module 310 is located below the tray storage bin 312 and is driven by the moving module 310 to lift and lower the tray. Lifting platform 311 moves to the full material tray position, where the full material tray is placed onto the lifting platform 311. Then, the moving module 310 drives the lifting platform 311 to move to the corresponding position, where the four-axis industrial robot picks up the material. After the material is picked up, the moving module 310 drives the lifting platform 311 to the empty material tray position. The lifting platform 311 lifts the empty material tray, causing the empty material tray placement compartment to lock the empty material tray. Then, the lifting platform 311 resets, thus unloading the empty material tray.

[0058] In summary, the working principle of this invention is as follows: the mesh storage component 31 moves the tray containing the mesh to below the first four-axis industrial robot 33. After the mesh storage component 31 moves the tray to the set position, the first four-axis industrial robot 33 starts and grabs 5 meshes from the tray at once, moving them to the mesh calibration component 32. After the first four-axis industrial robot 33 and the mesh calibration component 32 adjust and correct the position of the 5 meshes, the first four-axis industrial robot 33 places the 5 meshes on the assembly fixture 24. Then, the gap drive component drives the turntable 22 to rotate and transport the assembly fixture 24 containing the meshes to the housing loading mechanism 40.

[0059] The housing storage component 41 moves the tray containing the housings to below the second four-axis industrial robot 43. After the housing storage component 41 moves the tray to the set position, the second four-axis industrial robot 43 starts and grabs five nets from the tray at once, moving them to the housing calibration component 42. After the second four-axis industrial robot 43 and the housing calibration component 42 adjust and correct the position of the five housings, the second four-axis industrial robot 43 places the five housings on the assembly fixture 24 and assembles the housings and nets together. Then, the gap drive component drives the turntable 22 to rotate and transport the assembly fixture 24 containing the nets and housings to the welding mechanism 50. After the assembly fixture 24 is rotated and transported to the welding mechanism 50, the lifting cylinder 521 drives the horizontal plate 523 to move down, so that the horizontal pressure plate presses the housings and nets together to facilitate welding by the dual-group galvanometer laser welding machine 53.

[0060] After the welding mechanism 50 welds the mesh and the shell together, the gap drive assembly drives the turntable 22 to move the welded assembly to the vision inspection mechanism 60. The vision inspection mechanism 60 takes pictures of the assembly on the assembly fixture 24 and transmits the pictures to the PLC control device. The PLC control device analyzes and judges the pictures. After the PLC control device judges, it feeds back the signal to the finished product storage mechanism 70. At the same time, the lifting assembly 241 pushes the welded assembly out of the limit hole. The third and fourth axis industrial robots 73 execute the instructions fed back by the PLC control device and place the good products and defective products in the finished product storage assembly 71 and the defective product storage assembly 72 in sequence.

[0061] The wireless Bluetooth headset ear mesh welding machine of this invention automates the assembly and welding of the ear mesh and the shell, greatly improving production efficiency and reducing the labor intensity of producers. Simultaneously, through the setting of multiple calibration components, precise alignment of the mesh and shell is ensured during the assembly process, avoiding problems such as misalignment of the steel mesh or weak welding, thus guaranteeing the subsequent performance of the headset. Through a carefully designed mechanical structure and intelligent control system, an efficient, precise, and reliable production process is achieved.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
