DETAILED DESCRIPTION

[0035] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example:

[0036] An auxiliary hot stamping device for earphone shell, see Figure 1-Figure 5 , including a hot stamping machine body 1, a pull-out plate 2 is slidably connected to the hot stamping machine body 1, a placement plate 3 is placed on the top of the pull-out plate 2, two placement blocks 5 are symmetrically connected to the left and right sides of the top of the placement plate 3, and two semicircular blocks 51 are symmetrically connected to the top of the placement block 5. An elastic support block 52 is slidably connected to the semicircular block 51. The elastic support block 52 consists of a slide rod, a support block and a compression spring. The support block is slidably connected to the semicircular block 51 through the slide rod, and the compression spring is sleeved on the slide rod. The compression spring abuts against the semicircular block 51 and the support block, and the support block back One side of the semicircular block 51 is a curved surface. The upper shell of the earphone shell 201 is placed on the support block and pressed down. Since the side of the support block facing away from the semicircular block 51 is a curved surface, the upper shell moves downward to squeeze the support block toward the semicircular block 51, and the compression spring is compressed accordingly. The compression spring enables the support block to support and fix the upper shell on the placement block 5, and since the side of the support block facing away from the semicircular block 51 is a curved surface, the support block can better fit with the inner wall of the upper shell. There are two connecting blocks 53 symmetrically connected to the left and right sides of the top of the placement block 5. The block 53 is slidably connected with an elastic support plate 54, which is composed of a slide rod, a support plate and a compression spring. The support plate is slidably connected to the connecting block 53 through the slide rod, and the compression spring is sleeved on the slide rod. The compression spring abuts against the connecting block 53 and the support plate. The side of the support plate facing away from the connecting block 53 is a curved surface. The lower shell of the earphone shell 201 is placed on the support plate and pressed down. Since the side of the support plate facing away from the connecting block 53 is a curved surface, the lower shell moves downward to squeeze the support plate toward the direction close to the connecting block 53, and the compression spring is compressed accordingly. The support plate can support and fix the lower shell on the placement block 5, and since the side of the support plate facing away from the connecting block 53 is a curved surface, the support plate can better fit the inner wall of the lower shell. A circular pressure plate 4 is hinged on the rear side of the placement plate 3. The top and inner bottom of the circular pressure plate 4 are both provided with openings for placing the film 200. A mounting groove is provided in the lower part of the circular pressure plate 4, and the mounting groove is connected to the opening on the lower side. A clamping component is provided in the mounting groove on the circular pressure plate 4, a clamping component is provided on the top of the pull-out plate 2, and a pushing component is provided between the clamping component and the hot stamping machine body 1.

[0037] When the earphone shell 201 needs to be hot stamped, first place the upper shell of the earphone shell 201 on the placement block 5, and the upper shell of the earphone shell 201 can be supported and fixed on the placement block 5 by the elastic support block 52, then place the lower shell of the earphone shell 201 on the placement block 5, and the lower shell of the earphone shell 201 can be supported and fixed on the placement block 5 by the elastic support plate 54, and then put the film 200 into the circular pressing plate 4 through the opening at the top of the circular pressing plate 4, and then rotate the circular pressing plate 4 downward to cover the circular pressing plate 4 on the placement plate 3, so that the film 200 is aligned with the placement plate 3 and attached to the surface of the earphone shell 201, so that the film 200 can be positioned by the circular pressing plate 4, and the operator does not need to manually adjust the film 200 repeatedly to align the film 200 with the placement plate 3, thereby saving time and effort, and thus improving work efficiency. The film 200 can be clamped and fixed in the circular pressure plate 4 through the clamping component to prevent the film 200 from being displaced in the circular pressure plate 4 when the circular pressure plate 4 is rotated downward, and then the pull-out plate 2 is pushed backward into the hot stamping machine body 1 to move the earphone shell 201 into the hot stamping machine body 1 for hot stamping. In the process of the pull-out plate 2 driving the clamping component to move into the hot stamping machine body 1, the pushing component pushes the clamping component to clamp and fix the placement plate 3 on the pull-out plate 2 to prevent the placement plate 3 from being displaced during hot stamping and affecting the hot stamping of the earphone shell 201. After the earphone shell 201 is stamped, the pull-out plate 2 is pulled forward from the stamping machine body 1, so that the placement plate 3, the circular pressure plate 4 and the earphone shell 201 are moved out of the stamping machine body 1. Then, the circular pressure plate 4 is rotated upward to tear the film 200 from the earphone shell 201. Since the earphone shell 201 is supported and fixed on the placement block 5 by the elastic support block 52 and the elastic support plate 54, the earphone shell 201 will not be lifted up when the film 200 is torn off. In this way, the film 200 can be quickly torn off from the earphone shell 201, which can save time and effort and further improve work efficiency. In the process of the pull-out plate 2 driving the clamping assembly to move out of the stamping machine body 1, the clamping assembly loosens the placement plate 3, so that the placement plate 3 can be removed from the pull-out plate 2, thereby facilitating the replacement of the next placement plate 3 with the earphone shell 201 to be stamped.

[0038] See also Figure 3-Figure 4 In the present invention, the clamping assembly includes a fixed clamping plate 61 connected to the mounting groove of the circular pressure plate 4, and a movable clamping plate 63 is rotatably connected to the fixed clamping plate 61 through a rotating shaft 62. The movable clamping plate 63 is located on the rear side of the fixed clamping plate 61, and a torsion spring I 65 is connected between the movable clamping plate 63 and the fixed clamping plate 61. Two shift rods 64 are symmetrically connected to the rotating shaft 62, and a through groove is symmetrically opened on the lower front side of the circular pressure plate 4 for the shift rod 64 to rotate up and down.

[0039] Initially, the lever 64 is in a horizontal state, the movable clamping plate 63 is in a vertical state and is in close contact with the fixed clamping plate 61. When the film 200 is to be placed in the return pressure plate 4, the lever 64 is pushed upward to allow the rotating shaft 62 to drive the movable clamping plate 63 to rotate downward and disengage from the fixed clamping plate 61, and the torsion spring I 65 is compressed accordingly. When the film 200 is placed in the return pressure plate 4, the lever 64 is released. Under the reset action of the torsion spring I 65, the rotating shaft 62 drives the movable clamping plate 63 to rotate upward and reset, so that the movable clamping plate 63 cooperates with the fixed clamping plate 61 to clamp the film 200 in the return pressure plate 4 to prevent the film 200 from being displaced in the return pressure plate 4 when the return pressure plate 4 rotates downward. When the film 200 has been used once and needs to be replaced or taken out for cleaning, the above operation can be repeated to loosen the film 200.

[0040] See also Figure 5-Figure 6 In the present invention, the clamping assembly includes two mounting plates 71 symmetrically connected to the top of the pull-out plate 2. A clamping plate 73 is slidingly connected to the mounting plate 71 through a sliding rod 72, and a tension spring 74 is connected between the clamping plate 73 and the mounting plate 71.

[0041] See also Figure 5-Figure 6 In the present invention, the pushing assembly includes a push plate I 81 and a push plate II 82. The push plates I 81 are connected to the sides of the left and right sliding rods 72 facing each other. The rear side of the push plate I 81 is an inclined surface. Two push plates II 82 are symmetrically connected to the left and right sides of the hot stamping machine body 1. The front side of the push plate II 82 is an inclined surface. The two push plates I 81 can contact the two push plates II 82 respectively during the process of moving into the hot stamping machine body 1.

[0042] In the process of the pull-out plate 2 moving backward into the hot stamping machine body 1, it drives the mounting plate 71, the sliding rod 72 and the clamping plate 73 to move backward, so that the push plate I81 moves backward and contacts the push plate II82. When the inclined surface on the rear side of the push plate I81 contacts the inclined surface on the front side of the push plate II82, the push plate I81 continues to move backward and the inclined surface on its rear side is squeezed by the inclined surface on the front side of the push plate II82, so that the two push plates I81 approach each other. The two push plates I81 approach each other and the sliding rod 72 pushes the two clamping plates 73 to approach each other, so as to clamp and fix the placement plate 3 on the pull-out plate 2, and the tension spring 74 is stretched accordingly. This can avoid the displacement of the placement plate 3 during the hot stamping work and affect the hot stamping of the earphone shell 201. During the process of the pull-out plate 2 moving forward out of the hot stamping machine body 1, the push plate I 81 is driven forward to disengage from the push plate II 82. Under the reset action of the tension spring 74, the clamping plate 73 moves away from the placement plate 3 to loosen the placement plate 3, so as to facilitate the removal of the placement plate 3 from the pull-out plate 2, thereby facilitating the replacement of the next placement plate 3 on which the earphone shell 201 to be hot stamped is placed.

[0043] See also Figure 7-Figure 9 In the present invention, a pushing assembly is also included, which includes a U-shaped pushing block 91 connected to the rear side of the top of the pulling plate 2, and two push rods 93 are symmetrically and slidingly connected to the lower part of the rear side of the circular pressure plate 4. A pushing plate 92 is connected between the rear sides of the two push rods 93, and the pushing plate 92 contacts the U-shaped pushing block 91. Two flaps 94 are symmetrically connected to the bottom of the movable clamping plate 63, and the two flaps 94 are respectively in contact with the two push rods 93.

[0044] Initially, the pushing plate 92 is squeezed by the U-shaped pushing block 91, and the flip plate 94 is squeezed by the pushing rod 93. The flip plate 94 is in a horizontal state, the movable clamping plate 63 is in a horizontal state and is disengaged from the fixed clamping plate 61, and the torsion spring I 65 is in a compressed state. When the return pressure plate 4 rotates downward, it drives the pushing plate 92 to rotate downward and disengage from the U-shaped pushing block 91 through the pushing rod 93. After the pushing plate 92 is disengaged from the U-shaped pushing block 91, under the resetting action of the torsion spring I 65, the movable clamping plate 63 drives the flip plate 94 to rotate to a vertical state, so that the movable clamping plate 63 clamps and fixes the film 200. In the process of rotating the flip plate 94 to the vertical state, the pushing rod 93 is squeezed to drive the pushing plate 92 to move away from the return pressure plate 4. The push plate 92 is squeezed by the U-shaped push block 91, and the push rod 93 is driven to move in the direction close to the circular pressure plate 4, so that the push rod 93 pushes the flap 94 to rotate to a horizontal state, thereby driving the movable clamping plate 63 to rotate to a horizontal state and disengage from the fixed clamping plate 61 to loosen the film 200, and the torsion spring I 65 is compressed accordingly, so that the film 200 can be automatically fixed in the process of the circular pressure plate 4 closing downward, and the film 200 can be automatically loosened in the process of the circular pressure plate 4 opening upward, so that the film 200 can be easily taken in and put out.

[0045] See also Figure 10-12 In the present invention, a locking assembly is also included, which includes an L-shaped hook block 101 slidably connected to the front side of the top of the placement plate 3 through a slide groove. The top of the L-shaped hook block 101 is an inclined surface. A support spring 102 is connected between the L-shaped hook block 101 and the placement plate 3. A wedge block 103 is connected to the front side of the top of the circular pressure plate 4. The front side of the hot stamping machine body 1 is connected to a fixed plate 104, and the fixed plate 104 is located below the pull-out plate 2. A 7-shaped push plate 105 is connected to the front side of the fixed plate 104. A through hole is opened on the front side of the pull-out plate 2 for the 7-shaped push plate 105 to pass through.

[0046] The circular pressure plate 4 rotates downward, driving the wedge block 103 to rotate downward and contact the L-shaped hook block 101. When the inclined surface on the wedge block 103 contacts the inclined surface at the top of the L-shaped hook block 101, the wedge block 103 continues to rotate downward and squeezes the inclined surface at the top of the L-shaped hook block 101 through the inclined surface thereon, so that the L-shaped hook block 101 moves backward, and the support spring 102 is compressed accordingly. When the wedge block 103 passes over the top of the L-shaped hook block 101, under the resetting action of the support spring 102, the L-shaped hook block 101 moves forward to lock the wedge block 103, thereby locking the circular pressure plate 4 to prevent the circular pressure plate 4 from swinging upward to affect the hot stamping of the earphone shell 201 during hot stamping, thereby improving stability. When the pulling plate 2 drives the placing plate 3, the circular pressure plate 4, the wedge block 103 and the L-shaped hook block 101 forward from the hot stamping machine body 1, the L-shaped hook block 101 then contacts the 7-shaped push plate 105, and the 7-shaped push plate 105 presses the L-shaped hook block 101, so that the L-shaped hook block 101 is disengaged from the wedge block 103, thereby releasing the lock on the wedge block 103 and the circular pressure plate 4, thereby facilitating the circular pressure plate 4 to be rotated upward and opened.

[0047] See also Figure 13 In the present invention, it also includes a circular unloading rod 11 hinged to the left side of the top of the placement plate 3, and a receiving groove for accommodating the circular unloading rod 11 is opened on the placement plate 3 and the placement block 5.

[0048] The earphone shell 201 on the elastic support block 52 and the elastic support plate 54 can be removed at once by rotating the circular unloading rod 11 upwards, so as to facilitate the removal of the hot-stamped earphone shell 201.

[0049] See also Figure 13 In the present invention, a torsion spring II 12 connected between the placement plate 3 and the return pressure plate 4 is also included.

[0050] The circular pressure plate 4 rotates downward to compress the torsion spring II 12. When the wedge block 103 disengages from the L-shaped hook block 101 to release the lock on the circular pressure plate 4, the torsion spring II 12 resets the circular pressure plate 4 and rotates upward to reset it. In this way, the operator does not need to manually rotate the circular pressure plate 4 upward, which can save time and effort and further improve work efficiency.
