Description

Technical Field

[0001] This invention relates to a headphone case pressure-maintaining device and a method for maintaining headphone case pressure using the device, belonging to the technical field of headphone product manufacturing equipment. Background Technology

[0002] Helmet-style or over-ear headphones consist of two earpieces and a connecting section between them. During the production process, foam covers need to be installed on the earpieces. These foam covers are glued to the earpieces and then pressed for approximately 10 seconds to ensure a secure bond. Accurate positioning of the foam covers is crucial; any deviation will render them unusable. Currently, the pressing process is typically done manually, which is time-consuming, labor-intensive, and inefficient. Each step requires 1-2 operators, significantly increasing production costs. Furthermore, because the connecting part is curved and elastic, the end faces of the two earpieces are not parallel to each other in a natural state. It is very difficult to press the two earpiece covers simultaneously. Currently, the two earpiece covers are usually pressed separately, and the other earpiece is pressed after one earpiece is pressed. This results in low production efficiency. Therefore, it is necessary to develop a device that can press the two earpiece covers simultaneously to replace manual pressing and press the two earpiece covers of the helmet-mounted headset at the same time, so as to improve the production efficiency of the helmet-mounted headset cover pressing process and ensure the accurate position of the covers on the earpieces. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide a headphone case pressure-holding device, which is used for pressure holding of headphone cases in the production of helmet-style headphones. This device can simultaneously hold the headphone cases of both earpieces of helmet-style headphones with high pressure holding efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: to provide a headphone case pressure-holding device for pressurizing the headphone case during headphone production, including a frame, a working platform on the top of the frame, and a product positioning module for positioning the headphone product and a product pressure-holding module for pressurizing the headphone case on the working platform.

[0005] Preferably, the product positioning module includes a horizontal longitudinal slide rail mounted on a working platform, a first mounting seat slidably mounted on the horizontal longitudinal slide rail, two leather sleeve conforming mounting blocks mounted on the first mounting seat, the two leather sleeve conforming mounting blocks being arranged opposite each other, and each of the opposite end faces of the two leather sleeve conforming mounting blocks being provided with a leather sleeve mounting hole, the shape of the leather sleeve mounting hole being consistent with the shape of the leather sleeve, and a first cylinder being arranged horizontally longitudinally on the working platform, the first cylinder including a piston rod, the outer end of the piston rod of the first cylinder being fixedly connected to the first mounting seat.

Each of the two second mounting seats is provided with a contouring pressure plate. A leather sleeve contouring hole is provided on the outer end face of the contouring pressure plate. The contouring pressure plate on the two second mounting seats corresponds to two leather sleeve contouring mounting blocks. The outer end face of the contouring pressure plate is parallel to the end face of the corresponding leather sleeve contouring mounting block (i.e., the end face with the leather sleeve mounting hole). The height of the center of the leather sleeve contouring hole is consistent with the height of the center of the leather sleeve mounting hole. A hydraulic cylinder is provided on each of the pair of mounting plates. The outer end of the piston rod of the hydraulic cylinder is fixedly connected to the second mounting seat.

[0009] Preferably, a second horizontal slide rail is provided between the upper parts of the pair of mounting plates, and the upper ends of the two second mounting seats are respectively slidably mounted on the second horizontal slide rail.

[0011] Preferably, there are two product positioning modules and two product pressure holding modules, which are arranged side by side on the work platform.

[0012] The present invention also provides a method for maintaining the pressure of an earphone case using the above-mentioned earphone case pressure-maintaining device, comprising the following steps: (1) The earphone product is manually placed on the first mounting seat of the product positioning module in the earphone leather cover pressure holding device. The earphone part of the earphone product is placed into the leather cover mounting holes of the two leather cover contour mounting blocks on the first mounting seat. The foam leather cover is glued to the earphone part. The second cylinder drives the positioning block to move horizontally and laterally so that the positioning block presses the connection part of the earphone product near the earphone part, thus fixing the earphone part.

The contouring pressure plate squeezes the foam leather case in the leather case contouring hole and maintains the squeeze for about 10 seconds to complete the pressure holding process of the foam leather case. The foam leather case is firmly attached to the earphone part.

[0013] Preferably, after step (3) is completed, the hydraulic cylinder drives the second mounting seat to slide in the opposite direction on the first horizontal transverse slide rail and the second horizontal transverse slide rail, the contour plate retracts and resets, the second cylinder drives the positioning block to move in the opposite horizontal transverse direction and reset, the first cylinder drives the first mounting seat to slide in the opposite direction on the horizontal longitudinal slide rail, the first mounting seat and the leather case contour mounting block retract and reset, and wait for the leather case pressure holding process of the next headphone product.

By positioning the two headphone cover parts through the product positioning module, the pressure holding of the two headphone cover parts of the helmet-type headphones can be performed simultaneously. The pressure holding efficiency is high, and the position of the cover parts on the headphone parts is accurate, thereby improving the product qualification rate. Attached Figure Description

[0018] Please see Figures 1 to 4 The present invention includes: an earphone case pressure-holding device, which includes a frame 1, a working platform 2 on the top of the frame 1, and a product positioning module 3 for positioning the earphone product and a product pressure-holding module 4 for holding the earphone case pressure.

[0019] The product positioning module 3 includes a horizontal longitudinal slide rail 5 mounted on a working platform 2. A first mounting base 6 is slidably mounted on the horizontal longitudinal slide rail 5. Two leather sleeve conforming mounting blocks 7 are mounted on the first mounting base 6. The two leather sleeve conforming mounting blocks 7 are arranged opposite each other. Each of the opposite end faces of the two leather sleeve conforming mounting blocks 7 is provided with a leather sleeve mounting hole 8. The shape of the leather sleeve mounting hole 8 is consistent with the shape of the leather sleeve. A first cylinder 9 is horizontally and longitudinally mounted on the working platform 2. The first cylinder 9 includes a piston rod. The outer end of the piston rod of the first cylinder 9 is fixedly connected to the first mounting base 6.

[0020] A positioning block 10 is provided on the side of the leather sleeve conformal mounting block 7. A second cylinder 11 is provided on the first mounting base 6 for driving the positioning block 10 to move horizontally. The outer end of the piston rod of the second cylinder 11 is fixedly connected to the lower end of the positioning block 10.

[0021] The leather sleeve conformal mounting block 7 is equipped with a sensing fiber 12 for sensing the presence of the leather sleeve, preventing the leather sleeve from shifting or deforming, thereby improving the pressure holding accuracy.

[0022] The product pressure holding module 4 includes a pair of vertically arranged mounting plates 13. A first horizontal transverse slide rail 14 is arranged between the lower parts of the pair of mounting plates 13. The first horizontal transverse slide rail 14 is located above the horizontal longitudinal slide rail 5. Two second mounting seats 15 are slidably arranged on the first horizontal transverse slide rail 14. A contoured pressure plate 16 is arranged on each of the two second mounting seats 15. A leather sleeve contoured hole 17 is arranged on the outer end face of the contoured pressure plate 16. The contoured pressure plate 16 on the two second mounting seats 15 corresponds to two leather sleeve contoured mounting blocks 7 respectively. The outer end face of the contoured pressure plate 16 is parallel to the end face of the corresponding leather sleeve contoured mounting block 7 (i.e., the end face with the leather sleeve mounting hole 8). The height of the center of the leather sleeve contoured hole 17 is the same as the height of the center of the leather sleeve mounting hole 8. A hydraulic cylinder 18 is arranged on each of the pair of mounting plates 13. The outer end of the piston rod of the hydraulic cylinder 18 is fixedly connected to the second mounting seat 15. The hydraulic cylinder 18 is connected to the hydraulic system of the equipment. A pressure sensor 23 is installed on the contour plate 16 to sense the pressure. The hydraulic system is equipped with a pressure regulating valve 24 and an oil pressure damper 25, which can adjust the pressure parameters of the hydraulic cylinder 18 to achieve precise pressure holding. It is suitable for leather sleeve products of different sizes.

[0023] A second horizontal slide rail 19 is provided between the upper parts of the pair of mounting plates 13, and the upper ends of the two second mounting seats 15 are respectively slidably mounted on the second horizontal slide rail 19. The second horizontal slide rail 19 can further increase the stability of the second mounting seats 15 when sliding horizontally.

[0024] A control unit 20 is installed on the frame 1. The control unit 20 includes a PLC controller or microcomputer controller and several necessary operation buttons. A foot switch 21 is installed below the frame 1. The foot switch 21, the first cylinder 9, the second cylinder 11, and the hydraulic cylinder 18 are connected to the control unit 20 via wires. Automatic start-up and shutdown of the equipment and parameter adjustment are achieved through PLC programming of the control unit 20, thereby improving production efficiency.

[0025] There are two product positioning modules 3 and two product pressure holding modules 4, which are arranged side by side on the work platform 2.

[0026] When the headphone case pressure-holding device of the present invention is in operation, the headphone product is manually placed on the first mounting base 6, the headphone part is placed into the case mounting hole 8, and the foam case is glued to the headphone part. The connecting part of the headphone product is pressed by the product cover plate 22. The control unit 20 controls the second cylinder 11 to drive the positioning block 10 to move horizontally. The positioning block 10 presses the connecting part of the headphone product near the headphone part, fixing the headphone part. The sensing fiber optic 12 senses the headphone part, and then the foot switch 21 is pressed. The first cylinder 9 drives the first mounting base 6 to slide on the horizontal longitudinal slide rail 5, so that the first mounting base 6 and the two case contour mounting blocks 7 slide to the product pressure-holding module 4. The two case contour mounting blocks 7 are horizontally opposite to the contour pressure plates 16 on the two second mounting bases 15 respectively. The foam case on the headphone part is aligned with the case contour hole 17. The hydraulic cylinder 18 drives the second mounting base 15 to slide on the first horizontal transverse slide rail 14 and the second horizontal transverse slide rail 19, driving the contour pressure plate 16 to move horizontally. The contouring plate 16 moves to the corresponding leather case contouring mounting block 7 and approaches it. At this time, part of the foam leather case is in the leather case mounting hole 8 and the other part is in the leather case contouring hole 17. When the contouring plate 16 approaches the leather case contouring mounting block 7, it squeezes the foam leather case and maintains this squeeze for about 10 seconds to complete the pressure holding process of the foam leather case. The foam leather case is firmly attached to the earphone part (the contouring plate 16 is equipped with a pressure sensor 23 to sense the pressure of the contouring plate 16 on the leather case. The pressure sensor 23 is connected to the control unit 20). Then, the hydraulic cylinder 18 drives the second mounting seat 15 to slide in the opposite direction on the second horizontal transverse slide rail 19. The contouring plate 16 retracts and returns to its original position. The second cylinder 11 drives the positioning block 10 to move in the opposite horizontal transverse direction to reset. The first cylinder 9 drives the first mounting seat 6 to slide in the opposite direction on the horizontal longitudinal slide rail 5. The first mounting seat 6 and the leather case contouring mounting block 7 retract and reset, waiting for the leather case pressure holding process of the next earphone product. Furthermore, the equipment has two pressure-holding mechanisms that can operate simultaneously, improving the efficiency of pressure-holding production for leather sleeves. The entire pressure-holding process requires no manual intervention, which significantly reduces human error and improves product qualification rates, adapting to diverse production line needs. In addition, the equipment's modular design facilitates maintenance and upgrades, further optimizing enterprise resource utilization.

[0027] The present invention also provides a method for maintaining the pressure of an earphone case using the above-mentioned earphone case pressure-maintaining device, comprising the following steps: (1) The headphone product is manually placed on the first mounting seat 6 of the product positioning module 3 in the headphone case pressure holding device. The headphone part of the headphone product is placed into the case mounting holes 8 of the two case-contouring mounting blocks 7 on the first mounting seat 6. The foam case is glued to the headphone part. The second cylinder 11 drives the positioning block 10 to move horizontally and laterally so that the positioning block 10 presses the connection part of the headphone product near the headphone part, thus fixing the headphone part. (2) The sensing fiber 12 on the leather sleeve contour mounting block 7 senses the headphone part, and then the foot switch 21 is pressed. The first cylinder 9 drives the first mounting seat 6 to slide on the horizontal longitudinal slide rail 5, so that the first mounting seat 6 and the two leather sleeve contour mounting blocks 7 slide to the product pressure holding module 4. The two leather sleeve contour mounting blocks 7 are horizontally opposite to the contour pressure plates 16 on the two second mounting seats 15 respectively. The foam leather sleeve on the headphone part is directly opposite the leather sleeve contour hole 17 on the outer end face of the contour pressure plate 16. (3) The hydraulic cylinder 18 drives the second mounting base 15 to slide on the first horizontal transverse slide rail 14 and the second horizontal transverse slide rail 19, which drives the contouring pressure plate 16 to move horizontally. The contouring pressure plate 16 moves to the corresponding leather case contouring mounting block 7 and approaches the leather case contouring mounting block 7. The foam leather case is in the leather case contouring hole 17. The contouring pressure plate 16 squeezes the foam leather case in the leather case contouring hole 17 and maintains the squeeze for about 10 seconds to complete the pressure holding process of the foam leather case. The foam leather case is firmly attached to the headphone part.
