Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of earphone manufacturing, in particular to an earphone dispensing jig and a dispensing device. Background Art
[0002] At present, in order to facilitate the fixing of the speaker and the main control board, the earphones are usually designed to include a front shell and a middle shell, wherein the speaker is fixed on the front shell, the main control board is fixed on the middle shell, and an FPC (flexible circuit board) is connected between the speaker and the main control board. The front shell and the middle shell need to be fixed by gluing. When gluing the front shell or the middle shell, the flexible circuit board connected to the speaker will block part of the glue path on the front shell or the middle shell, resulting in the inability to complete the gluing in one go. The gluing needs to be completed in two times. Currently, when gluing for the second time, most people manually lift up the FPC and perform glue repair, or use another set of jigs to complete the glue repair. Whether manually or using another set of jigs, both methods require multiple operations of taking and placing materials on the earphones, which is labor-intensive for the operators and results in low gluing efficiency. Moreover, during the second gluing process, the operators are more likely to touch part of the glue path completed by the first gluing, resulting in poor gluing quality.
[0003] Therefore, there is a need to improve the existing technology. Utility Model Content
[0004] The utility model provides a glue dispensing jig and glue dispensing equipment for headphones, which mainly solve the technical problems of high work intensity, low work efficiency and difficulty in ensuring glue dispensing quality caused by repeated taking out and putting out of the headphones for secondary glue dispensing due to the limitation of FPC during glue dispensing of the front shell and the middle shell of the existing headphones.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A glue dispensing jig for headphones, the headphones comprising a first shell and a second shell, the first shell being provided with a speaker, the second shell being provided with a main control board, a flexible circuit board being electrically connected between the speaker and the main control board, the glue dispensing jig comprising a base, the base being provided with at least one glue dispensing station, each of the glue dispensing stations being provided with a first seat body and a second seat body arranged adjacently, the first seat body being provided with a first groove for accommodating the first shell, the second seat body being provided with a second groove for accommodating the second shell, the first seat body being rotatably connected to the base, and the second seat body being fixedly connected to the base.
[0007] In one technical solution, a first limiting surface and a second limiting surface are provided on the base, wherein the first limiting surface is used to limit the final position of the first base body when rotating relative to the base in a first direction, and the second limiting surface is used to limit the final position of the first base body when rotating relative to the base in a direction opposite to the first direction;
[0008] When the first seat body abuts against the first limiting surface, the flexible circuit board covers the first glue spot area of the first shell and covers the second glue spot area of the second shell. When the first seat body abuts against the second limiting surface, at least one of the first glue spot area or the second glue spot area is exposed.
[0009] In one of the technical solutions, the first limiting surface and the second limiting surface are both offset against the first seat by magnetic attraction.
[0010] In one of the technical solutions, an adjustment seat is connected between the second seat body and the base, and an adjustment hole is provided on the adjustment seat. The adjustment hole is used to adjust the height of the second seat body relative to the base.
[0011] In one of the technical solutions, the dispensing jig further includes a first cover plate rotatably connected to the first base, and the first cover plate is used to confine the first shell within the first groove.
[0012] In one technical solution, the first cover plate is magnetically engaged with the first base.
[0013] In one of the technical solutions, the dispensing jig further includes a second cover plate rotatably connected to the second base body, and the second cover plate is used to confine the second shell in the second groove.
[0014] In one technical solution, the second cover plate is magnetically engaged with the second base.
[0015] In one of the technical solutions, a handle is fixed to one side of the first base.
[0016] In one of the technical solutions, the axis of rotation of the first seat body relative to the base points in a vertical direction.
[0017] The present application also provides a dispensing device, including the dispensing fixture described in any of the above technical solutions.
[0018] Compared with the prior art, the headphone dispensing fixture provided by the present invention has at least the following beneficial effects:
[0019] When using this solution, the first shell of the headset (such as the front shell) can be placed in the first groove of the first base, and the second shell of the headset (such as the middle shell) can be placed in the second groove of the second base. Then, glue is applied to the part of the glue application area on the first shell or / and the second shell that is not blocked by the flexible circuit board. After the glue application is completed, the first base is driven to rotate to a suitable position relative to the base so that the other part of the glue application area on the first shell or / and the second shell that was originally blocked by the flexible circuit board is exposed. At this time, a second glue filling process can be performed. Using the glue application jig of this solution, both glue applications can be performed on the same jig. The operator does not need to use two sets of jigs, that is, the operator does not need to take and place the headset multiple times, thereby reducing work intensity and costs and reducing the risk of damage to the appearance of the headset. At the same time, the glue application efficiency of the headset shell is greatly improved. Moreover, the operator will not accidentally touch the first glue application area. Therefore, the jig of this solution is also conducive to ensuring the high quality of glue application, that is, it is conducive to ensuring excellent sealing between the headset shell and the shell.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0032] Please also refer to Figures 1 to 3, an embodiment of the present invention provides a dispensing jig for headphones, which includes a base 1, on which at least one dispensing station 11 is provided. In order to improve the efficiency of dispensing, the dispensing jig of this solution is provided with two dispensing stations 11, that is, this solution can complete the dispensing operation of two headphones at one time, and each dispensing station 11 is provided with a first seat body 2 and a second seat body 3 arranged adjacent to each other, wherein the first seat body 2 is rotatably connected to the base 1 with a rotating shaft 4 as a rotating axis, wherein the axis of the rotating shaft 4 is preferably pointing in the vertical direction, and the second seat body 3 is fixed on the base 1. Specifically, a first groove 21 is provided on the first base body 2, and a second groove 31 is provided on the second base body 3. The first groove 21 is used to accommodate the first shell with a speaker on the earphone, and the second groove 31 is used to accommodate the second shell with a main control board on the earphone. A flexible circuit board 5 is connected between the speaker and the main control board. The first shell is also called the front shell of the earphone in the earphone field, and the second shell can be only the middle shell of the earphone, or the second shell can be a shell module composed of the middle shell and the back shell of the earphone.
[0033] When using this solution, the first shell (front shell) of the earphone can be placed in the first groove 21 of the first base 2, and the second shell (middle shell) of the earphone can be placed in the second groove 31 of the second base 3, and then the glue spotting area on the first shell or / and the second shell that is not blocked by the flexible circuit board 5 can be glued once. After the glue spotting is completed, Figure 3 As shown, the first seat body 2 is driven to rotate to a suitable position relative to the base 1, so that another part of the glue spotting area on the first shell and / or the second shell that was originally blocked by the flexible circuit board 5 is exposed. At this time, a secondary glue filling process can be performed. Using the glue spotting fixture of this solution, both glue spotting can be achieved on the same fixture, and the operator does not need to use two sets of fixtures, that is, the operator does not need to take and put the earphones multiple times, thereby reducing work intensity and costs and reducing the risk of damage to the appearance of the earphones. At the same time, it also greatly improves the glue spotting efficiency of the earphone shell, and the operator will not accidentally touch the first glue spotting area. Therefore, the fixture of this solution is also conducive to ensuring the high quality of glue spotting, that is, it is conducive to ensuring excellent sealing between the front shell and the middle shell of the earphone.
[0034] Preferably, during the first glue dispensing, this solution dispenses glue on both the first shell and the second shell. During the second glue filling, this solution preferably performs a second glue dispensing on another part of the glue dispensing area on the first shell originally blocked by the flexible circuit board 5 and another part of the glue dispensing area on the second shell originally blocked by the flexible circuit board 5, so as to ensure excellent sealing after the front shell and the middle shell are combined.
[0035] Preferably, this solution also performs glue application on preset positions on the main control board before or after the second glue application. That is, the first glue application between the front shell and the middle shell, the second glue application, and the glue application on the main control board are all implemented using the jig of this solution, which is beneficial to improving the production efficiency of the headphones.
[0036] Please refer to the Figures 1 to 3 In this solution, a first limiting surface 12 and a second limiting surface 13 are provided on the base 1. The first limiting surface 12 is used to limit the final position of the first seat body 2 rotating relative to the base 1 along the first direction. Figure 1 As shown, when the first seat body 2 abuts against the first limiting surface 12, it is the position for gluing the earphone once, and the second limiting surface 13 is used to limit the final position of the first seat body 2 rotating relative to the base 1 in the opposite direction of the first direction, as shown in FIG. Figure 3 As shown, when the first base 2 abuts against the second limiting surface 13, it is the position for the second glue filling of the earphone. By setting the first limiting surface 12 and the second limiting surface 13, the earphone can be maintained in a suitable position during the first glue filling or the second glue filling process, thereby improving the accuracy of the glue filling of the earphone. More specifically, when the first base 2 abuts against the first limiting surface 12, the flexible circuit board 5 covers the first glue filling area of the first shell and the second glue filling area of the second shell. When the first base 2 abuts against the second limiting surface 13, at least one of the first glue filling area or the second glue filling area is exposed, so that the glue filling area during the second glue filling of the earphone can form a complete annular area with the glue filling area of the first glue filling, thereby ensuring that the subsequent front shell and the middle shell can have excellent sealing after being combined.
[0037] Please refer to the Figures 1 to 3 , the first limiting surface 12 and the second limiting surface 13 are both abutted against the first seat body 2 by magnetic attraction, so as to improve the firmness of the first seat body 2 abutting against the first limiting surface 12 or the second limiting surface 13, thereby further improving the accuracy of gluing the earphone shell. Optionally, a first magnet can be provided at both the first limiting surface 12 and the second limiting surface 13, and a second magnet with opposite magnetic properties to the first magnet can be provided on the first seat body 2. Optionally, a magnet can also be provided only on the first seat body 2, and then a metal part with both the first limiting surface 12 and the second limiting surface 13 can be fixed on the base 1. In this case, the first seat body 2 can also be magnetically attracted to the first limiting surface 12 and the second limiting surface 13 respectively.
[0038] See also Figure 4An adjustment seat 6 is connected between the second seat body 3 and the base 1. The adjustment seat 6 is provided with an adjustment hole 61 extending in the vertical direction. The second seat body 3 can be fixed to the adjustment seat 6 by passing a bolt through the adjustment hole 61 and screwing it onto the second seat body 3. At this time, the height of the second seat body 3 relative to the base 1 can be adjusted by changing the position of the bolt passing through the adjustment hole 61. Through such a design, it is possible to eliminate processing errors and assembly errors, ensuring that the position of the second seat body 3 relative to the first seat body 2 is more accurate, so that the dispensing equipment can accurately dispense glue on both the first shell and the second shell. In addition, in order to facilitate the operator to operate the first seat body 2 to rotate relative to the base 1, this solution fixes a handle 7 on one side of the first seat body 2.
[0039] Please refer to the Figures 1 to 3 The dispensing jig also includes a first cover plate 8 and a second cover plate 9, wherein the first cover plate 8 is rotatably connected to the first base body 2 and cooperates with the first base body 2 by magnetic attraction, and the second cover plate 9 is rotatably connected to the second base body 3 and cooperates with the second base body 3 by magnetic attraction. The first cover plate 8 is used to limit the first shell in the first groove 21 to stabilize the position of the first shell, and the second cover plate 9 is used to limit the second shell in the second groove 31 to stabilize the position of the second shell, thereby improving the accuracy of dispensing on the earphone shell.
[0040] The present application also provides a dispensing device. In addition to the existing frame and a dispensing head connected to the frame and capable of being moved, the dispensing device also includes the aforementioned dispensing jig. When the dispensing head is moved, it can perform complete annular dispensing of glue on the first shell or the second shell on the dispensing jig. Optionally, the dispensing device may further include a drive mechanism that automatically drives the first seat 2 to rotate relative to the base 1, thereby completely freeing up labor and further improving the automation level of the headphones, thereby further improving the production efficiency of the headphones.
[0041] The above is merely a preferred embodiment of the present invention and only specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be imagined by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
