Description

Technical Field

[0001] This invention relates to the field of hot stamping technology for digital products, specifically to an auxiliary hot stamping device for earphone shells. Background Technology

[0002] Hot stamping is a process that uses the principle of heat transfer to transfer the aluminum layer from electroplated aluminum foil to the surface of the substrate to create a special metallic effect. Because the main material used in hot stamping is electroplated aluminum foil, it is also called electroplated aluminum hot stamping.

[0003] Headphones are becoming increasingly popular as a symbol of portable audio equipment. Before leaving the factory, headphones usually have logos or other personalized markings hot-stamped on the shell. Existing hot-stamping equipment typically places the headphone shell on a hot-stamping platform, then uses the equipment to hot-stamp the shell. After the hot-stamping is completed, the shell is removed from the platform and collected. Currently, the hot-stamping process for headphone shells is generally done manually, which results in poor continuity and low efficiency.

[0004] Based on the above-mentioned shortcomings, it is necessary to design an auxiliary hot stamping device for earphone shells, which can conveniently and efficiently collect earphone shells after hot stamping, thereby improving work efficiency and achieving continuity of hot stamping operations. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an auxiliary hot stamping device for headphone shells, comprising a frame, a mounting frame, a support, a collecting frame, a right-angled trapezoidal block, an electric bidirectional lead screw, a guide rod, a placement rack, and a hot stamping assembly. The mounting frame and collecting frame are both mounted on the top of the frame. A support is mounted on the rear side wall of the frame, and the support is equipped with a hot stamping assembly for hot stamping the headphone shell. The hot stamping assembly performs the hot stamping operation on the headphone shell. The mounting frame contains a parallel electric bidirectional lead screw and a guide rod. The electric bidirectional lead screw includes a bidirectional lead screw rotatably mounted on the mounting frame and a drive motor for rotating the bidirectional lead screw. Two placement racks are movably mounted between the electric bidirectional lead screw and the guide rod. The electric bidirectional lead screw has its threads passing through the placement frame, and the guide rod slides through the placement frame. The top front sides of the two placement frames have symmetrical grooves. The electric bidirectional lead screw rotates to drive the two placement frames to close together, thus forming the placement groove for the earphone shell. A right-angled trapezoidal block is installed between the front and rear parts of the mounting frame. The right-angled trapezoidal block is located between the two placement frames, and its inclined surface is tilted downwards towards the collection frame. When the electric bidirectional lead screw drives the two placement frames to move in opposite directions, the earphone shell placed in the placement groove of the two placement frames falls onto the inclined surface of the right-angled trapezoidal block. The inclined surface of the right-angled trapezoidal block transports the earphone shell that has completed the hot stamping operation to the collection frame, thus realizing convenient collection of the earphone shell.

[0006] Preferably, the hot stamping assembly includes a hot stamping film, a take-up and untake-up roller, a take-up roller, a power assembly, a rotating rod, a cylinder, and a hot stamping pressure plate. The take-up and untake-up rollers and the take-up roller are correspondingly installed on the left and right sides of the upper part of the support. A rotating rod is also rotatably installed on the left and right sides of the upper part of the support. The take-up and untake-up roller, the take-up roller, and the rotating rod are all located directly above the machine frame. The hot stamping film is installed on the take-up and untake-up roller, and is connected to the take-up roller via the rotating rod. A power assembly is installed on the rear side of the upper part of the support to drive the take-up and untake-up rollers and the take-up roller to rotate, thereby achieving the take-up, untake-up, and take-up of the hot stamping film. The power assembly includes a drive motor installed on the rear side of the upper part of the support, a pulley on the output shaft of the drive motor, and a mechanism connected to the rear of the take-up and untake-up rollers and the take-up roller. The system includes pulleys and a transmission belt that transmits power from the drive motor to the take-up and take-up reels. A cylinder is also installed on the upper front side of the bracket, positioned between the take-up and take-up reels. A hot stamping plate is connected to the lower end of the cylinder piston rod. The hot stamping plate consists of an upper and a lower plate, connected by a screw. During operation, the piston inside the cylinder moves downwards, driving the hot stamping plate downwards via the piston rod. The hot stamping plate contacts the hot stamping film and stamps the markings onto the earphone shell on the rack, thus performing the hot stamping operation on the earphone shell. The power unit drives the take-up and take-up reels to rotate, enabling the take-up and take-up of the hot stamping film.

[0007] Preferably, it further includes an air cushion, a cylindrical piston cylinder, a pull rope, a reversing rod, a spring, and a conduit. An air cushion is provided on one side of the inclined surface of the right-angled trapezoidal block. The cylindrical piston cylinder is installed inside the cavity of the right-angled trapezoidal block. A pull rope is connected to the end of the piston rod of the cylindrical piston cylinder. The end of the pull rope away from the piston rod of the cylindrical piston cylinder is connected to a placement frame. A reversing rod for changing the direction of the pull rope is provided at the upper part of the cavity of the right-angled trapezoidal block. The pull rope passes over the reversing rod. A spring is provided between the top of the cavity of the cylindrical piston cylinder and the piston. There is a connection between the cavity of the cylindrical piston cylinder and the air cushion. When the electric bidirectional screw drives the placement frame to move away from the right-angled trapezoidal block, the placement frame tightens the pull rope. The pull rope drives the piston in the cylindrical piston cylinder to move upward along the inner wall of the cylindrical piston cylinder. The spring is compressed, and the upward movement of the piston compresses the gas in the cylindrical piston cylinder and delivers it to the air cushion through the conduit. The air cushion expands, thereby providing damage protection for the earphone shell. When the electric bidirectional screw drives the two placement frames to move in opposite directions, under the action of the spring force, the spring returns to its original position, and the piston in the cylindrical piston cylinder moves downward to return to its original position.

[0008] Preferably, it also includes an n-shaped plate, a rectangular piston cylinder, a telescopic tube, a rectangular piston extrusion plate, a vertical rod, a figure-7 plate, a limiting airbag, and a second spring. An n-shaped plate is installed on one side wall of the hot stamping plate, and a rectangular piston cylinder is installed on the n-shaped plate. A rectangular piston extrusion plate is slidably disposed inside the rectangular piston cylinder. A vertical rod is connected to the bottom of the rectangular piston extrusion plate, and a figure-7 plate is connected to the lower end of the vertical rod. The figure-7 plate is positioned directly above the right-angled trapezoidal block. A second spring is disposed between the figure-7 plate and the bottom of the rectangular piston cylinder. A limiting airbag is installed on the back of the figure-7 plate, and the limiting airbag is connected to the inner cavity of the rectangular piston cylinder through a telescopic tube. When the hot stamping plate moves downwards, it drives... The n-shaped plate, rectangular piston cylinder, 7-shaped plate, and limiting airbag move downwards. When the 7-shaped plate and limiting airbag contact the top of the placement frame, the placement frame blocks the downward movement of the 7-shaped plate and limiting airbag. After the 7-shaped plate and limiting airbag are blocked, the 7-shaped plate pushes the vertical rod upwards in relative motion, the second spring is compressed, and the vertical rod drives the rectangular piston extrusion plate to move upwards along the inner wall of the rectangular piston cylinder. This compresses the gas in the inner cavity of the rectangular piston cylinder and delivers the gas to the limiting airbag through the telescopic tube, causing the limiting airbag to expand. The expansion of the limiting airbag limits the earphone shell to prevent the earphone shell from shifting during the hot stamping operation.

[0009] Preferably, the limiting airbag is adapted to the placement groove formed by the two placement frames.

[0010] Preferably, it also includes an L-bar, a rack, a third spring, a second rotating rod, a gear, and a bidirectional spiral plate. The backs of the two mounting brackets are symmetrically connected to the L-bar. A rack is slidably mounted on the upper part of the L-bar. A third spring is provided between the rack and the L-bar. A second rotating rod parallel to the first rotating rod is rotatably mounted on the upper part of the bracket. The end of the second rotating rod passes through the bracket and is connected to a gear that can mesh with the rack. A bidirectional spiral plate is provided on the second rotating rod. The horizontal movement of the rack drives the gear to rotate, and the gear drives the second rotating rod to rotate. The second rotating rod drives the bidirectional spiral plate to rotate synchronously. When the bidirectional spiral plate rotates, it spreads and flattens the hot stamping film.

[0011] Preferably, the teeth on the rack mesh unidirectionally with the teeth on the gear, thereby enabling the rack to drive the gear to rotate unidirectionally.

[0012] Preferably, when the two placement frames move toward each other, the placement frame drives the rack and pinion to mesh with the gear.

[0013] Preferably, the front ends of both the take-up and take-up wheels are fitted with limiting sleeves to limit the hot stamping film.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The electric bidirectional screw drives the placement racks on both sides of the right-angled trapezoidal block to move in opposite directions. When the two placement racks move in opposite directions, the placement groove formed by the two placement racks provides a placement platform for the hot stamping operation of the earphone shell. When the two placement racks move in opposite directions, the earphone shell that has completed the hot stamping operation slides along the inclined surface of the right-angled trapezoidal block into the collection frame, thereby realizing a convenient collection operation for the earphone shell that has completed the hot stamping operation.

[0015] 2. When the two side mounting brackets move away from the right-angled trapezoidal block, the mounting brackets tighten the pull ropes, which in turn drive the piston inside the cylindrical piston cylinder to move upward along the inner wall of the cylindrical piston cylinder. This compresses the gas inside the cylindrical piston cylinder and delivers it to the air cushion through the conduit. The air cushion expands, thus providing damage protection for the headphone shell as it slides down.

[0016] 3. When the cylinder drives the hot stamping plate to move downward, the hot stamping plate drives the n-shaped plate, rectangular piston cylinder, rectangular piston extrusion plate, vertical rod, 7-shaped plate, and limiting airbag to move downward simultaneously. When the 7-shaped plate and limiting airbag come into contact with the placement frame, the placement frame blocks the downward movement of the 7-shaped plate and limiting airbag. The 7-shaped plate then pushes the vertical rod upward to move relative to it. The vertical rod drives the rectangular piston extrusion plate to move upward along the inner wall of the rectangular piston cylinder. This compresses the gas in the inner cavity of the rectangular piston cylinder and delivers it to the limiting airbag through the telescopic tube. The limiting airbag expands, thereby limiting the earphone shell on the placement frame, thus preventing the earphone shell from shifting during the hot stamping operation and ensuring the hot stamping operation of the earphone shell.

[0017] 4. When the placement racks on both sides of the right-angled trapezoidal block move towards each other in the direction of the right-angled trapezoidal block, the placement rack drives the rack and gear to mesh through the L rod. This enables the horizontal movement of the placement rack to drive the gear to rotate. The rotation of the gear drives the second rotating rod to rotate, and the second rotating rod drives the bidirectional spiral plate on it to rotate synchronously. The reverse movement of the teeth on both sides of the bidirectional spiral plate enables the hot stamping film to be unfolded and laid flat, thereby avoiding wrinkles in the hot stamping film and providing convenience for the hot stamping operation.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Example: A device for auxiliary hot stamping of earphone shells, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the device includes a frame 1, a mounting frame 101, a bracket 2, a collection frame 5, a right-angled trapezoidal block 6, an electric bidirectional lead screw 7, a guide rod 8, a placement rack 9, and a hot stamping assembly. The mounting frame 101 and the collection frame 5 are both mounted on the top of the frame 1. A bracket 2 is mounted on the rear side wall of the frame 1, and a hot stamping assembly for hot stamping the earphone shell is mounted on the bracket 2. The hot stamping assembly performs the hot stamping operation on the earphone shell. The mounting frame 101 contains a parallel electric bidirectional lead screw 7 and a guide rod 8. The electric bidirectional lead screw 7 includes a bidirectional lead screw rotatably mounted on the mounting frame 101 and a drive motor that drives the bidirectional lead screw to rotate. Two placement racks 9 are movably mounted between the electric bidirectional lead screw 7 and the guide rod 8. The electric bidirectional lead screw 7 has a bidirectional... A lead screw thread passes through the placement frame 9, and a guide rod 8 slides through the placement frame 9. The top front sides of the two placement frames 9 have symmetrical grooves. The electric bidirectional lead screw 7 rotates to drive the two placement frames 9 to close together, thus forming a placement groove for the earphone shell. A right-angled trapezoidal block 6 is installed between the front and rear parts of the mounting frame 101. The right-angled trapezoidal block 6 is located between the two placement frames 9, and the inclined surface of the right-angled trapezoidal block 6 is inclined downward towards the collection frame 5. When the electric bidirectional lead screw 7 drives the two placement frames 9 to move in opposite directions, the earphone shell placed in the placement groove of the two placement frames 9 falls onto the inclined surface of the right-angled trapezoidal block 6. The inclined surface of the right-angled trapezoidal block 6 transports the earphone shell that has completed the hot stamping operation to the collection frame 5, thereby realizing the convenient collection of the earphone shell.

[0032] like Figure 2 and Figure 3As shown, the hot stamping assembly includes a hot stamping film 200, a take-up and untake-down roller 201, a take-up roller 202, a power assembly 203, a rotating rod 204, a cylinder 3, and a hot stamping pressure plate 4. The take-up and untake-down roller 201 and the take-up roller 202 are correspondingly installed on the left and right sides of the upper part of the support 2. A rotating rod 204 is also rotatably installed on the left and right sides of the upper part of the support 2. The take-up and untake-down roller 201, the take-up roller 202, and the rotating rod 204 are all located directly above the frame 1. The hot stamping film 200 is installed on the take-up and untake-down roller 201, and the hot stamping film 200 is connected to the take-up roller 202 via the rotating rod 204. A power assembly 203 is installed on the rear side of the upper part of the support 2 to drive the take-up and untake-down roller 201 and the take-up roller 202 to achieve the take-up and untake-down and take-up of the hot stamping film 200. The power assembly 203 includes a drive motor installed on the rear side of the upper part of the support 2, a pulley on the output shaft of the drive motor, and a pulley connected to the take-up and untake-down roller. 201. The pulley connected to the rear of the take-up reel 202 and the transmission belt that transmits the power of the drive motor to the take-up reel 201 and the take-up reel 202. A cylinder 3 is also installed on the upper front side of the bracket 2. The cylinder 3 is located between the take-up reel 201 and the take-up reel 202. The lower end of the piston rod of the cylinder 3 is connected to the hot stamping plate 4. The hot stamping plate 4 is divided into an upper hot stamping plate 4 and a lower hot stamping plate 4. The upper hot stamping plate 4 and the lower hot stamping plate 4 are connected by a screw. In use, the piston in the inner cavity of the cylinder 3 moves down, and the piston drives the hot stamping plate 4 to move down through the piston rod. The hot stamping plate 4 contacts the hot stamping film 200 and stamps the marking on the hot stamping film 200 onto the earphone shell on the placement rack 9, realizing the hot stamping operation on the earphone shell. The power unit 203 drives the take-up reel 201 and the take-up reel 202 to rotate, so as to realize the take-up and take-down function of the hot stamping film 200.

[0033] like Figure 6As shown, it also includes an air cushion 10, a cylindrical piston cylinder 11, a pull rope 12, a reversing rod 13, a spring 14, and a conduit 15. An air cushion 10 is provided on one side of the inclined surface of the right-angled trapezoidal block 6. The cylindrical piston cylinder 11 is installed inside the cavity of the right-angled trapezoidal block 6. A pull rope 12 is connected to the end of the piston rod of the cylindrical piston cylinder 11. The end of the pull rope 12 away from the piston rod of the cylindrical piston cylinder 11 is connected to a placement frame 9. A reversing rod 13 is provided at the upper part of the cavity of the right-angled trapezoidal block 6 to change the direction of the pull rope 12. The pull rope 12 passes over the reversing rod 13. A spring 14 is provided between the top of the cavity of the cylindrical piston cylinder 11 and the piston. The air cushions 10 are connected by a conduit 15. When the electric bidirectional screw 7 drives the placement frame 9 to move away from the right-angled trapezoidal block 6, the placement frame 9 tightens the pull rope 12. The pull rope 12 drives the piston in the cylindrical piston cylinder 11 to move upward along the inner wall of the cylindrical piston cylinder 11. The spring 14 is compressed. The upward movement of the piston compresses the gas in the cylindrical piston cylinder 11 and delivers it to the air cushion 10 through the conduit 15. The air cushion 10 expands, thereby providing damage protection for the earphone shell. When the electric bidirectional screw drives the two placement frames 9 to move in opposite directions, the spring 14 returns to its original position under the action of the elastic force of the spring 14. The piston in the cylindrical piston cylinder 11 moves downward to return to its original position.

[0034] like Figure 7 and Figure 8As shown, it also includes an n-shaped plate 16, a rectangular piston cylinder 17, a telescopic tube 171, a rectangular piston extrusion plate 18, a vertical rod 19, a 7-shaped plate 20, a limiting airbag 21, and a second spring 22. An n-shaped plate 16 is installed on one side wall of the hot stamping plate 4. A rectangular piston cylinder 17 is installed on the n-shaped plate 16. A rectangular piston extrusion plate 18 is slidably disposed inside the rectangular piston cylinder 17. A vertical rod 19 is connected to the bottom of the rectangular piston extrusion plate 18. A 7-shaped plate 20 is connected to the lower end of the vertical rod 19. The 7-shaped plate 20 is positioned directly above the right-angled trapezoidal block 6. The limiting airbag 21 fits into the placement groove formed by the two placement frames 9. A second spring 22 is disposed between the 7-shaped plate 20 and the bottom of the rectangular piston cylinder 17. A limiting airbag 21 is installed on the back of the 7-shaped plate 20. The limiting airbag 21 and the inner cavity of the rectangular piston cylinder 17 are connected by a telescopic tube 22. When the shrink tube 171 is connected, the hot stamping plate 4 moves downward, causing the n-shaped plate 16, the rectangular piston cylinder 17, the 7-shaped plate 20, and the limiting airbag 21 to move downward. When the 7-shaped plate 20 and the limiting airbag 21 move downward and contact the top of the placement frame 9, the placement frame 9 blocks the downward movement of the 7-shaped plate 20 and the limiting airbag 21. After the 7-shaped plate 20 and the limiting airbag 21 are blocked, the 7-shaped plate 20 pushes the vertical rod 19 to move upward relative to each other. The spring 22 is compressed, and the vertical rod 19 drives the rectangular piston extrusion plate 18 to move upward along the inner wall of the rectangular piston cylinder 17. This compresses the gas in the inner cavity of the rectangular piston cylinder 17 and delivers the gas to the limiting airbag 21 through the telescopic tube 171, causing the limiting airbag 21 to expand. The expansion of the limiting airbag 21 limits the earphone shell to prevent the earphone shell from shifting during the hot stamping operation.

[0035] like Figure 9 and Figure 10 As shown, it also includes an L-bar 23, a rack 24, a third spring 25, a second rotating rod 26, a gear 27, and a bidirectional spiral plate 28. The backs of the two mounting brackets 9 are symmetrically connected to the L-bar 23. The rack 24 is slidably mounted on the upper part of the L-bar 23. A third spring 25 is provided between the rack 24 and the L-bar 23. A second rotating rod 26, parallel to the first rotating rod 204, is rotatably mounted on the upper part of the bracket 2. The end of the second rotating rod 26, passing through the bracket 2, is connected to a gear 27 that meshes with the rack 24. The teeth on the rack 24 and the teeth on the gear 27... The rack 24 drives the gear 27 to rotate in one direction. When the two mounting frames 9 move towards each other, the mounting frame 9 drives the rack 24 to mesh with the gear 27. The rotating rod 26 is equipped with a bidirectional spiral plate 28. The spiral shape of the bidirectional spiral plate 28 moves in opposite directions. The horizontal movement of the rack 24 drives the gear 27 to rotate. The gear 27 drives the rotating rod 26 to rotate. The rotating rod 26 drives the bidirectional spiral plate 28 to rotate synchronously. When the bidirectional spiral plate 28 rotates, it unfolds and flattens the hot stamping film 200.

[0036] like Figure 11As shown, the front ends of both the take-up and take-up rollers 201 and 202 are fitted with limiting sleeves 29 to limit the hot stamping film 200.

[0037] In practical application, the electric bidirectional lead screw 7 drives the placement frame 9 to move in opposite directions, thereby constructing a placement groove for the earphone shell. The earphone is then placed in the placement groove constructed by the two placement frames 9. The cylinder 3 operates, and its piston rod drives the hot stamping plate 4 downwards. The hot stamping plate 4 presses the hot stamping film 200 onto the surface of the earphone shell, thus performing the hot stamping operation. Subsequently, the power assembly 203 drives the take-up and undo wheel 201 to take up and undo the hot stamping film 200, and the take-up wheel 202 retracts the hot stamping film 200 after the hot stamping operation. When the hot stamping plate 4 moves downwards, it drives the n-shaped plate 16, the rectangular piston cylinder 17, the rectangular piston extrusion plate 18, the vertical rod 19, the 7-shaped plate 20, and the limiter. The airbag 21 moves downwards synchronously. When the 7-shaped plate 20 and the limiting airbag 21 come into contact with the placement frame 9, the placement frame 9 blocks the downward movement of the 7-shaped plate 20 and the limiting airbag 21. Under the blocking force of the placement frame 9, the 7-shaped plate 20 pushes the vertical rod 19 upwards for relative movement. The vertical rod 19 drives the rectangular piston extrusion plate 18 to move upwards along the inner wall of the rectangular piston cylinder 17. The spring 22 is compressed and deformed, thereby compressing the gas in the inner cavity of the rectangular piston cylinder 17 and transporting it to the limiting airbag 21 through the telescopic tube 171. The limiting airbag 21 inflates, thereby limiting the earphone shell in the placement slot on the placement frame 9, providing convenience for the subsequent hot stamping operation of the earphone shell. After the earphone shell has completed the hot stamping operation, the electric bidirectional wire... Rod 7 drives the two placement frames 9 to move away from the right-angled trapezoidal block 6. The earphone shell located in the placement slot constructed by the two placement frames 9 slides into the collection frame 5 along the inclined surface of the right-angled trapezoidal block 6. When the two placement frames 9 move away from the right-angled trapezoidal block 6, the placement frames 9 tighten the pull rope 12. The pull rope 12, under force, drives the piston in the cylindrical piston cylinder 11 to move upward along the inner wall of the cylindrical piston cylinder 11. The spring 14 is compressed, thereby compressing the gas in the cylindrical piston cylinder 11 and delivering the gas to the air cushion 10 through the conduit 15. The air cushion 10 expands, providing damage protection for the earphone shell to slide down. When the electric bidirectional lead screw 7 drives the two placement frames 9 to move in opposite directions, the placement frames 9 release the pull rope 12. Under the elastic force of the spring 14, When in use, the piston inside the cylindrical piston cylinder 11 returns to its original position, creating a negative pressure inside the cylindrical piston cylinder 11. The gas in the air cushion 10 is then transported into the cylindrical piston cylinder 11 through the conduit 15, causing the air cushion 10 to contract and facilitating the closing of the two placement racks 9. Simultaneously, when the placement racks 9 move towards each other, the placement rack 9 drives the rack 24 to mesh with the gear 27 via the L-rod 23. This horizontal movement of the placement rack 9 drives the gear 27 to rotate, which in turn drives the rotating rod 26 to rotate. The rotating rod 26 then drives the bidirectional spiral plate 28 to rotate synchronously. The spirals on both sides of the bidirectional spiral plate 28 move in opposite directions, thereby unfolding and flattening the hot stamping film 200 to both sides, preventing wrinkles and ensuring the hot stamping operation.
