Description

Technical Field

[0001] The invention relates to the technical field of hot stamping of digital products, and in particular to an auxiliary hot stamping device for an earphone shell. Background Art

[0002] The hot stamping process uses the principle of heat pressure transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate to form a special metallic effect. Because the main material used for hot stamping is electroplated aluminum foil, hot stamping is also called electroplated aluminum hot stamping.

[0003] As a symbol of portable audio, earphones are becoming more and more popular. Before leaving the factory, earphones are usually hot-stamped with a logo or other personalized logo on the earphone shell. The existing hot-stamping device usually places the earphone shell on a hot-stamping platform, and then performs hot-stamping operation on the earphone shell through the hot-stamping equipment. After the hot-stamping operation is completed, the earphone shell is taken back from the hot-stamping platform and collected. At present, the earphone shell is generally loaded and unloaded manually during the hot-stamping operation, which has the defects of poor hot-stamping continuity and low efficiency.

[0004] Based on the above defects, it is necessary to design an auxiliary hot stamping device for earphone shells, which is used to conveniently and efficiently collect the earphone shells that have completed the hot stamping operation, so as to improve work efficiency and achieve the continuity of the hot stamping operation. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides such an auxiliary hot stamping device for earphone shells, including a frame, a mounting frame, a bracket, a collection frame, a right-angle trapezoidal block, an electric bidirectional screw, a guide rod, a placement rack and a hot stamping component, the mounting frame and the collection frame are both installed on the top of the frame, a bracket is installed on the rear side wall of the frame, a hot stamping component for hot stamping the earphone shell is arranged on the bracket, and the earphone shell is hot stamped by the hot stamping component, and an electric bidirectional screw and a guide rod parallel to each other are installed in the mounting frame, wherein the electric bidirectional screw comprises a bidirectional screw rotatably installed on the mounting frame and a driving motor driving the bidirectional screw to rotate, and two placement racks are movably installed between the electric bidirectional screw and the guide rod, wherein The bidirectional screw thread of the electric bidirectional screw passes through the placement rack, and the guide rod slides through the placement rack. Symmetrical grooves are opened on the front sides of the tops of the two placement racks. The electric bidirectional screw rotates to drive the two placement racks to enclose and form a placement groove for the earphone shell. A right-angled trapezoidal block is installed between the front and rear parts of the installation frame. The right-angled trapezoidal block is arranged between the two placement racks, and the inclined surface of the right-angled trapezoidal block is inclined downward toward the collection frame. When the electric bidirectional screw drives the two placement racks to move in opposite directions, the earphone shells placed in the placement grooves of the two placement racks will fall onto the inclined surface of the right-angled trapezoidal block, and the earphone shells that have completed the hot stamping operation will be transported to the collection frame through the inclined surface of the right-angled trapezoidal block, thereby realizing convenient collection of the earphone shells.

[0006] Preferably, the hot stamping assembly includes a hot stamping film, a pay-off reel, a take-up reel, a power assembly, a first rotating rod, a cylinder, and a hot stamping platen. The pay-off reel and the take-up reel are respectively installed on the left and right sides of the upper part of the bracket. The first rotating rod is also rotatably installed on the left and right sides of the upper part of the bracket. The pay-off reel, the take-up reel, and the first rotating rod are all located directly above the frame. The hot stamping film is installed on the pay-off reel, and the hot stamping film is connected to the take-up reel through the first rotating rod. A power assembly for driving the pay-off reel and the take-up reel to rotate to realize the pay-off and take-up of the hot stamping film is installed at the rear side of the upper part of the bracket. The power assembly includes a driving motor installed at the rear side of the upper part of the bracket, a pulley on the output shaft of the driving motor, a pulley connected to the rear parts of the pay-off reel and the take-up reel, and a transmission belt for transmitting the power of the driving motor to the pay-off reel and the take-up reel. A cylinder is also installed at the front side of the upper part of the bracket. The cylinder is located between the pay-off reel and the take-up reel. The lower end of the piston rod of the cylinder is connected to the hot stamping platen. The hot stamping platen is divided into an upper hot stamping platen and a lower hot stamping platen. The upper hot stamping platen and the lower hot stamping platen are connected by a screw rod. During use, the piston in the cylinder cavity moves downward, and the piston drives the hot stamping platen to move downward through the piston rod. The hot stamping platen contacts the hot stamping film and stamps the logo on the hot stamping film onto the earphone shell on the placement rack, realizing the hot stamping operation on the earphone shell. The power assembly drives the pay-off reel and the take-up reel to rotate to realize the pay-off and take-up functions of the hot stamping film.

[0007] Preferably, it further includes an air cushion, a columnar piston cylinder, a pull rope, a reversing rod, a first spring, and a conduit. An air cushion is arranged on the inclined surface side of the right-angled trapezoidal block. A columnar piston cylinder is installed in the cavity of the right-angled trapezoidal block. The end of the piston rod of the columnar piston cylinder is connected to a pull rope. The end of the pull rope far away from the piston rod of the columnar piston cylinder is connected to a placement rack. A reversing rod for changing the direction of the pull rope is arranged at the upper part of the cavity of the right-angled trapezoidal block. The pull rope bypasses the reversing rod. A first spring is arranged between the top of the cavity of the columnar piston cylinder and the piston. The cavity of the columnar piston cylinder is communicated with the air cushion through a conduit. When the electric bidirectional lead screw drives the placement rack to move away from the right-angled trapezoidal block, the placement rack tightens the pull rope, drives the piston in the columnar piston cylinder to move upward along the inner wall of the columnar piston cylinder through the pull rope, the first spring is compressed, the piston moves upward to compress the gas in the columnar piston cylinder and transports it to the air cushion through the conduit, and the air cushion expands, thereby providing anti-damage protection for the earphone shell; when the electric bidirectional lead screw drives the two placement racks to move towards each other, under the action of the elastic force of the first spring, the first spring resets, and the piston in the columnar piston cylinder moves downward to reset.

[0008] Preferably, it further includes an n-shaped plate, a rectangular piston cylinder, a telescopic tube, a rectangular piston extrusion plate, a vertical rod, a 7-shaped plate, a limiting airbag and a second spring. An n-shaped plate is installed on one side wall of the hot stamping pressing plate. A rectangular piston cylinder is installed on the n-shaped plate. A rectangular piston extrusion plate is slidably arranged in the rectangular piston cylinder. A vertical rod is connected to the bottom of the rectangular piston extrusion plate. The lower end of the vertical rod is connected to a 7-shaped plate. The 7-shaped plate is located directly above the right-angled trapezoidal block. A second spring is arranged between the 7-shaped plate and the bottom of the rectangular piston cylinder. A limiting airbag is installed on the back of the 7-shaped plate. The limiting airbag is communicated with the inner cavity of the rectangular piston cylinder through a telescopic tube. When the hot stamping pressing plate moves downward, it drives the n-shaped plate, the rectangular piston cylinder, the 7-shaped plate and the limiting airbag to move downward. When the 7-shaped plate and the limiting airbag move downward and contact the top of the placement rack, the placement rack blocks the downward movement of the 7-shaped plate and the limiting airbag. After the 7-shaped plate and the limiting airbag are blocked, the 7-shaped plate pushes the vertical rod to move upward relatively. The second spring is compressed. The vertical rod drives the rectangular piston extrusion plate to move upward along the inner wall of the rectangular piston cylinder. Thereby, the gas in the inner cavity of the rectangular piston cylinder is compressed and the gas is transported to the limiting airbag through the telescopic tube, so that the limiting airbag expands. The earphone shell is limited by the expansion of the limiting airbag to prevent the earphone shell from displacing during the hot stamping operation.

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

[0010] Preferably, it further includes an L-shaped rod, a rack, a third spring, a second rotating rod, a gear and a bidirectional spiral plate. L-shaped rods are symmetrically connected to the backs of the two placement racks. A rack is slidably installed on the upper part of the L-shaped rod. A third spring is arranged between the rack and the L-shaped rod. A second rotating rod parallel to the first rotating rod is rotatably installed on the upper part of the bracket. The end of the second rotating rod passing through the bracket is connected with a gear that can mesh with the rack. A bidirectional spiral plate is arranged on the second rotating rod. The horizontal movement of the rack drives the gear to rotate. 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 unfolds and flattens the hot stamping film.

[0011] Preferably, the tooth shape on the rack meshes with the tooth shape on the gear unidirectionally, realizing the unidirectional rotation of the rack driving the gear.

[0012] Preferably, when the two placement racks move towards each other, the placement rack drives the rack and the gear to mesh.

[0013] Preferably, limiting sleeves for limiting the hot stamping film are sleeved on the front ends of the rewinding wheel and the winding wheel.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The placement racks on both sides of the right-angle trapezoidal block are driven by an electric bidirectional screw to move toward or in opposite directions. When the two placement racks move toward each other, the placement grooves constructed by the two placement racks provide a placement platform for the hot stamping operation of the earphone shells. When the two placement racks move in opposite directions, the earphone shells that have completed the hot stamping operation slide along the inclined surface of the right-angle trapezoidal block into the collection frame, thereby providing a convenient collection operation for the earphone shells that have completed the hot stamping operation.

[0015] 2. When the placement racks on both sides move in the direction away from the right-angled trapezoidal blocks, the placement racks tighten the pull ropes, and drive the piston in the cylindrical piston cylinder to move upward along the inner wall of the cylindrical piston cylinder through the pull ropes, thereby compressing the gas in the inner cavity of the cylindrical piston cylinder and transporting it to the air cushion through the conduit. The air cushion expands, thereby providing anti-damage protection for the downward slide of the earphone shell.

[0016] 3. When the cylinder drives the hot stamping plate to move downward, the hot stamping plate drives the n-type plate, rectangular piston cylinder, rectangular piston extrusion plate, vertical rod, 7-shaped plate and limiting airbag to move downward synchronously. When the 7-shaped plate and the limiting airbag come into contact with the placement rack, the placement rack blocks the downward movement of the 7-shaped plate and the limiting airbag, and the 7-shaped plate pushes the vertical rod to move upward relative to the vertical rod. The vertical rod drives the rectangular piston extrusion plate to move upward along the inner wall of the rectangular piston cylinder, thereby compressing the gas in the inner cavity of the rectangular piston cylinder and transporting it to the limiting airbag through the telescopic tube. The limiting airbag expands, thereby limiting the earphone shell on the placement rack, thereby avoiding displacement of the earphone shell during the hot stamping operation, thereby providing protection for the hot stamping operation of the earphone shell.

[0017] 4. When the placement racks on both sides of the right-angled trapezoidal block move toward each other in the direction of the right-angled trapezoidal block, the placement rack drives the rack to engage with the gear through the L rod, thereby realizing 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 thereon to rotate synchronously, and the function of spreading the hot stamping film is realized through the reverse movement of the teeth on both sides of the bidirectional spiral plate, so as to avoid wrinkles in the hot stamping film, thereby providing convenience for the hot stamping operation.

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

[0031] Embodiment: An auxiliary hot stamping device for earphone shells, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, it includes a machine frame 1, a mounting frame 101, a bracket 2, a collection box 5, a right 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 box 5 are both installed on the top of the machine frame 1. A bracket 2 is installed on the rear side wall of the machine frame 1, and a hot stamping assembly for hot stamping the earphone shell is arranged on the bracket 2. The earphone shell is hot stamped through the hot stamping assembly. Inside the mounting frame 101, an electric bidirectional lead screw 7 and a guide rod 8 that are parallel to each other are installed. The electric bidirectional lead screw 7 includes a bidirectional lead screw rotatably installed on the mounting frame 101 and a driving motor for driving the bidirectional lead screw to rotate. Two placement racks 9 are movably installed between the electric bidirectional lead screw 7 and the guide rod 8. The bidirectional lead screw of the electric bidirectional lead screw 7 threadedly penetrates through the placement rack 9, and the guide rod 8 slidably penetrates through the placement rack 9. Symmetric grooves are formed on the front sides of the tops of the two placement racks 9. By rotating the electric bidirectional lead screw 7, the two placement racks 9 are driven to close to form a placement groove for the earphone shell. A right trapezoidal block 6 is installed between the front and rear parts of the mounting frame 101. The right trapezoidal block 6 is arranged between the two placement racks 9, and the inclined surface of the right trapezoidal block 6 is inclined downward towards the collection box 5. When the electric bidirectional lead screw 7 drives the two placement racks 9 to move in opposite directions, the earphone shell placed in the placement groove of the two placement racks 9 will fall onto the inclined surface of the right trapezoidal block 6, and the earphone shell that has completed the hot stamping operation is conveyed into the collection box 5 through the inclined surface of the right trapezoidal block 6, thereby realizing the convenient collection of the earphone shell.

[0032] As Figure 2 and Figure 3As shown in the figure, the hot stamping assembly includes a hot stamping film 200, a winding and unwinding wheel 201, a winding wheel 202, a power assembly 203, a first rotating rod 204, a cylinder 3 and a hot stamping press plate 4. The winding and unwinding wheel 201 and the winding wheel 202 are respectively installed on the left and right sides of the upper part of the bracket 2. The first rotating rod 204 is also rotatably installed on the left and right sides of the upper part of the bracket 2. The winding and unwinding wheel 201, the winding wheel 202 and the first rotating rod 204 are all located directly above the frame 1. The hot stamping film 200 is installed on the winding and unwinding wheel 201, and the hot stamping film 200 is connected to the winding wheel 202 through the first rotating rod 204. A power assembly 203 for driving the winding and unwinding wheel 201 and the winding wheel 202 to rotate to realize the winding and unwinding of the hot stamping film 200 is installed at the rear side of the upper part of the bracket 2. The power assembly 203 includes a driving motor installed at the rear side of the upper part of the bracket 2, a pulley on the output shaft of the driving motor, a pulley connected to the rear parts of the winding and unwinding wheel 201 and the winding wheel 202, and a transmission belt for transmitting the power of the driving motor to the winding and unwinding wheel 201 and the winding wheel 202. A cylinder 3 is also installed at the front side of the upper part of the bracket 2. The cylinder 3 is located between the winding and unwinding wheel 201 and the winding wheel 202. The lower end of the piston rod of the cylinder 3 is connected to the hot stamping press plate 4. The hot stamping press plate 4 is divided into an upper hot stamping press plate 4 and a lower hot stamping press plate 4. The upper hot stamping press plate 4 and the lower hot stamping press plate 4 are connected by a screw rod. During use, the piston in the inner cavity of the cylinder 3 moves downward. The piston drives the hot stamping press plate 4 to move downward through the piston rod. The hot stamping press plate 4 contacts the hot stamping film 200 and stamps the logo 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 assembly 203 drives the winding and unwinding wheel 201 and the winding wheel 202 to rotate to realize the winding and unwinding function of the hot stamping film 200.

[0033] As Figure 6As shown in the figure, it further includes an air cushion 10, a columnar piston cylinder 11, a pull rope 12, a reversing rod 13, a first spring 14, and a conduit 15. An air cushion 10 is provided on the inclined surface side of the right trapezoidal block 6. A columnar piston cylinder 11 is installed inside the right trapezoidal block 6. The end of the piston rod of the columnar piston cylinder 11 is connected to a pull rope 12. The end of the pull rope 12 away from the piston rod of the columnar piston cylinder 11 is connected to a placement rack 9. A reversing rod 13 for changing the direction of the pull rope 12 is provided in the upper part of the inner cavity of the right trapezoidal block 6. The pull rope 12 bypasses above the reversing rod 13. A first spring 14 is provided between the top of the inner cavity of the columnar piston cylinder 11 and the piston. The inner cavity of the columnar piston cylinder 11 is communicated with the air cushion 10 through a conduit 15. When the electric bidirectional lead screw 7 drives the placement rack 9 to move away from the right trapezoidal block 6, the placement rack 9 tightens the pull rope 12, and drives the piston in the columnar piston cylinder 11 to move upward along the inner wall of the columnar piston cylinder 11 through the pull rope 12. The first spring 14 is compressed. The piston moves upward to compress the gas in the columnar piston cylinder 11 and transports it to the air cushion 10 through the conduit 15, and the air cushion 10 expands, thereby providing anti-damage protection for the earphone shell. When the electric bidirectional lead screw drives the two placement racks 9 to move towards each other, under the action of the elastic force of the first spring 14, the first spring 14 resets, and the piston in the columnar piston cylinder 11 moves downward to reset.

[0034] As Figure 7 and Figure 8As shown, it also includes an n-type 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 spring 22. An n-type plate 16 is installed on one side wall of the hot stamping plate 4, and a rectangular piston cylinder 17 is installed on the n-type plate 16. A rectangular piston extrusion plate 18 is slidably arranged in the rectangular piston cylinder 17. The bottom of the rectangular piston extrusion plate 18 is connected to a vertical rod 19, and the lower end of the vertical rod 19 is connected to a 7-shaped plate 20. The 7-shaped plate 20 is arranged just above the right-angled trapezoidal block 6. The limiting airbag 21 is adapted to the placement groove formed by the two placement racks 9. A spring 22 is arranged 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 171. The shrink tube 171 is connected, and when the hot stamping plate 4 moves downward, it drives the n-type plate 16, the rectangular piston cylinder 17, the 7-shaped plate 20 and the limiting airbag 21 downward. When the 7-shaped plate 20 and the limiting airbag 21 move downward and contact the top of the placement rack 9, the placement rack 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, the spring 22 is compressed, and the vertical rod 19 drives the rectangular piston squeezing plate 18 to move upward along the inner wall of the rectangular piston cylinder 17, thereby compressing the gas in the inner cavity of the rectangular piston cylinder 17 and transporting the gas to the limiting airbag 21 through the telescopic tube 171, so that the limiting airbag 21 expands, and the earphone shell is limited by the expansion of the limiting airbag 21 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 rod 23, a rack 24, a spring three 25, a rotating rod two 26, a gear 27 and a bidirectional spiral plate 28. The two placement racks 9 are symmetrically connected to the back with the L rod 23. The upper part of the L rod 23 is slidably mounted with a rack 24. A spring three 25 is arranged between the rack 24 and the L rod 23. The upper part of the bracket 2 is rotatably mounted with a rotating rod two 26 parallel to the rotating rod one 204. The rotating rod two 26 passes through the end of the bracket 2 and is connected to a gear 27 that can mesh with the rack 24. The tooth shape on the rack 24 is consistent with the tooth shape on the gear 27. The rack 24 is unidirectionally meshed to realize the unidirectional rotation of the gear 27 driven by the gear 27. When the two placement racks 9 move towards each other, the placement rack 9 drives the rack 24 to mesh with the gear 27. A bidirectional spiral plate 28 is provided on the rotating rod 26. 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, the hot stamping film 200 is unfolded and flattened.

[0036] like Figure 11As shown, limit sleeves 29 for limiting the hot stamping film 200 are sleeved on the front ends of the winding and unwinding wheel 201 and the winding wheel 202 respectively.

[0037] In specific application, the placement racks 9 are driven by the electric bidirectional screw 7 to move towards each other, thereby constructing a placement slot for the earphone shell, and then the earphone is placed in the placement slot constructed by the two placement racks 9, and the cylinder 3 works, and the cylinder 3 drives the hot stamping plate 4 to move downward through its piston rod, and the hot stamping plate 4 moves downward to press the hot stamping film 200 down to the surface of the earphone shell, thereby performing hot stamping on the earphone shell, and then, the power component 203 drives the retracting wheel 201 to retract the hot stamping film 200, and the hot stamping film 200 that has completed the hot stamping operation is retracted and recovered by the rewinding wheel 202; when the hot stamping plate 4 moves downward, the hot stamping plate 4 drives the n-type plate 16, the rectangular piston cylinder 17, the rectangular piston extrusion plate 18, the vertical rod 19, the 7-shaped plate 20 and the limit The airbag 21 moves downward synchronously. When the 7-shaped plate 20 and the limiting airbag 21 come into contact with the placement rack 9, the placement rack 9 blocks the downward movement of the 7-shaped plate 20 and the limiting airbag 21. The 7-shaped plate 20 and the limiting airbag 21 exert a blocking force on the placement rack 9, and the 7-shaped plate 20 pushes the vertical rod 19 to move upward relative to each other. The vertical rod 19 drives the rectangular piston extrusion plate 18 to move upward 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 expands, thereby limiting the earphone shell in the placement slot on the placement rack 9, which facilitates the subsequent hot stamping operation of the earphone shell. When the earphone shell completes the hot stamping operation, the electric bidirectional wire The rod 7 drives the two placement racks 9 to move in the direction away from the right-angled trapezoidal block 6, and the earphone shells located in the placement grooves constructed by the two placement racks 9 slide into the collection frame 5 along the inclined surface of the right-angled trapezoidal block 6. When the two placement racks 9 move in the direction away from the right-angled trapezoidal block 6, the placement racks 9 tighten the pull rope 12, and the pull rope 12 is forced to drive the piston in the columnar piston cylinder 11 to move upward along the inner wall of the columnar piston cylinder 11, and the spring 14 is compressed, thereby compressing the gas in the columnar piston cylinder 11 and transporting the gas to the air cushion 10 through the conduit 15. The air cushion 10 expands to provide anti-damage protection for the downward movement of the earphone shell; when the electric bidirectional screw rod 7 drives the two placement racks 9 to move toward each other, the placement rack 9 releases the pull rope 12, and under the action of the elastic force of the spring 14 Under the use, the piston in the columnar piston cylinder 11 is reset downward, negative pressure is formed in the columnar piston cylinder 11, and the gas in the air cushion 10 is transported to the columnar piston cylinder 11 through the conduit 15. The air cushion 10 contracts, which facilitates the encirclement of the two placement racks 9. At the same time, when the placement racks 9 move towards each other, the placement racks 9 drive the rack 24 to engage with the gear 27 through the L rod 23, thereby driving the gear 27 to rotate through the horizontal movement of the placement rack 9, and the gear 27 drives the rotating rod 26 to rotate, and the rotating rod 26 drives the bidirectional spiral plate 28 to rotate synchronously, and the spirals on both sides of the bidirectional spiral plate 28 move in opposite directions, thereby spreading and flattening the hot stamping film 200 to both sides to avoid wrinkles in the hot stamping film 200, thereby providing protection for the hot stamping operation.

The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations, improvements, and substitutions can be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
