Description

Technical Field

[0001] The present disclosure relates to a clamping device for an earphone and an earphone adhesive curing device including the clamping device. Background Art

[0002] The prior art solution is mainly aimed at the UV drying process of the adhesive of the earphone product. In this process, the UV light source (not shown) is placed on the Figure 1 The clamping device shown is placed directly above the earphone product to ensure that the adhesive can be evenly and effectively irradiated with ultraviolet rays, thereby achieving rapid curing of the adhesive. However, due to the structural characteristics of the earphone product and the structure of the existing clamping device, the product needs to be turned over during the drying process to ensure that the adhesive can be fully cured on both sides. This means that the entire drying process needs to be turned over and dried at least twice, which not only increases the complexity of the operation, but also prolongs the production cycle.

[0003] In addition, existing headphone adhesive curing devices (UV drying equipment) usually require manual door opening and closing. During the drying process, the operator needs to manually open the device door, put the product into the device, and then close the device door to start drying. After one side is dried, the operator manually opens the device door again, takes out the product, turns it over, and then puts it back into the device for a second drying. This manual operation is not only inefficient, but also prone to product quality problems due to improper operation.

[0004] In summary, the existing UV drying technology for earphone adhesives has the following problems:

[0005] Since it is necessary to turn over and dry at least twice, each time the adhesive needs to be completely cured, which greatly increases the total drying time and leads to low drying efficiency. On the production line, this waste of time will directly lead to reduced production efficiency and increased production costs.

[0006] Manual door opening and closing and flipping operations increase the complexity of operations. This not only requires operators to have a higher level of skills, but also requires more time and effort. At the same time, manual operations also increase the possibility of human errors, such as uneven curing of adhesives caused by improper operation.

[0007] Due to the need for manual turning and operation, the stability of product quality is difficult to guarantee. The operating habits and skill levels of different operators may lead to inconsistency in product quality, which in turn affects the overall quality of the product.

[0008] In summary, the existing UV drying technology for earphone adhesive has problems such as low drying efficiency, high operation complexity and poor quality stability. In order to solve these problems, it is necessary to develop a new clamping device and technical solution that can achieve uniform curing of adhesive in one go. Utility Model Content

[0055] Thus far, in order that the detailed description of the present disclosure herein can be better understood, and in order that the contribution of the present disclosure to the prior art can be better appreciated, the present disclosure has been fairly broadly outlined. Of course, embodiments of the present disclosure will be described below and will form the subject matter of the appended claims.

[0056] Likewise, those skilled in the art will recognize that the conception upon which the present disclosure is based can be easily used as the basis for designing other structures, methods and systems for implementing the several purposes of the present disclosure. Therefore, it is important that the appended claims should be considered to include such equivalent structures as long as they do not exceed the essence and scope of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The following drawings will provide a better understanding of the present disclosure and more clearly demonstrate the advantages of the present disclosure. The drawings described herein are for illustrative purposes only of selected embodiments, not all possible implementations, and are not intended to limit the scope of the present disclosure.

[0065] Figure 8 The internal structure of the earphone adhesive curing device according to the present disclosure is shown, wherein an ultraviolet light source and a conveying device are schematically shown. DETAILED DESCRIPTION

[0066] The specific implementation methods according to the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0067] Figures 2 to 6 A clamping device 2 for earphones 1 according to the present disclosure is shown. The clamping device 2 can clamp a plurality of earphones 1 therein. For example, Figure 2 In the figure, the clamping device 2 is shown to clamp four earphones 1 therein.

[0068] The earphone 1 includes a first earphone housing 1-1 and a second earphone housing 1-2. An adhesive is provided at the bonding surfaces of the first earphone housing 1-1 and the second earphone housing 1-2.

[0069] The first earphone shell 1-1 and the second earphone shell 1-2 together define a closed space. The closed space contains the main components of the earphone, such as the drive unit: this is the core part of the earphone, responsible for converting electrical signals into sound. For dynamic earphones, the drive unit usually includes a magnet, a coil and a vibrating membrane. When current passes through the coil, it is acted upon by a force in the magnetic field, causing the vibrating membrane to vibrate and produce sound. Dynamic iron earbuds use a balanced armature located in the center of the permanent magnetic field, which is transmitted to the center point of the micro-diaphragm through a precision connecting rod, generating vibrations and making sounds; Voice coil: In dynamic earphones, the voice coil is a coil wrapped around the driver unit. When current passes through, the voice coil will vibrate due to the magnetic field; Diaphragm: This is another key component in the driver unit. When the voice coil vibrates, the diaphragm will also vibrate, thereby producing sound; Magnet: Provides a magnetic field for the driver unit so that the voice coil can be affected by force when current passes through; Circuit board: Used to control the transmission and processing of audio signals, which may include functions such as volume control and noise cancellation; Microphone (for earphones with call function): Used to capture the user's voice for calls or voice input; Battery and charging contacts (for wireless or Bluetooth earphones): The battery provides power to the earphones, and the charging contacts are used to charge the battery.

[0070] Those skilled in the art will appreciate that, depending on the type of earphone, different components may be accommodated therein.

[0071] like Figure 4 and Figure 5 As shown, the clamping device 2 includes a base 3, a base connecting plate 4 connected to the base 3, and a plurality of spring pressure rods 5 arranged on the base connecting plate 4. The number of the spring pressure rods 5 is the same as the number of the earphones to be clamped. Figure 2 As shown, four spring pressure rods 5 are shown.

[0072] The base 3 and the base connecting plate 4 are made of metal materials, such as but not limited to aluminum alloy materials.

[0073] The base 3 is substantially U-shaped, and includes a base portion 3 - 1 and base support portions 3 - 2 extending vertically upward from both ends of the base portion 3 - 1 .

[0074] The two ends of the base connecting plate 4 are respectively connected and fixed to the two base supporting parts 3 - 2 through fasteners 6 .

[0075] A plurality of connecting plate through holes 4 - 1 are provided on the base connecting plate 4 along the length direction of the base connecting plate 4 , and the spring compression rods 5 pass through the corresponding connecting plate through holes 4 - 1 and fit in the connecting plate through holes 4 - 1 .

[0076] An open space is defined between the base connecting plate 4 and the base 3-1, wherein a plurality of earphones 1 waiting for the adhesive to cure can be accommodated. Figure 3 As shown, the ultraviolet light source of the earphone adhesive curing device can simultaneously irradiate the earphone from both sides of the earphone (the left and right sides, i.e., the ear-in-ear side of the earphone and the ear-outside side of the earphone) through the open space, that is, the ultraviolet light sources 10 arranged on both sides of the open space simultaneously irradiate the earphone 1 through the open space in a direction parallel to the bonding surface, thereby curing the adhesive. Compared with irradiating the ultraviolet light source from the upper direction of the earphone, with the aid of the clamping device 2 according to the present disclosure, the ultraviolet light source 10 can irradiate from both sides of the earphone 1, so that the irradiation area is increased, which is conducive to completing the adhesive curing in one go.

[0077] like Figure 3 As shown in the top view, two exemplary ultraviolet light sources 10 are located on both sides of the earphone 1, or in other words, on both sides of the clamping device 2.

[0078] The spring pressure rod 5 includes a pressure rod housing 5-1, a spring 5-2 and a pressure rod 5-3, wherein the spring 5-2 is held inside the pressure rod housing 5-1, the pressure rod 5-3 is slidably fitted inside the pressure rod housing 5-1, the spring 5-2 acts between the pressure rod housing 5-1 and the pressure rod 5-3 and applies a spring force to the pressure rod 5-3 in the direction toward the earphone. The pressure rod housing 5-1 is connected to the base connecting plate 4.

[0079] The pressure rod housing 5 - 1 and the pressure rod 5 - 3 are made of metal materials, such as but not limited to aluminum alloy materials.

[0080] The pressure rod 5 - 3 of the spring pressure rod 5 applies force toward the first earphone housing 1 - 1 , so that the second earphone housing 1 - 2 abuts against the base 3 , thereby clamping the earphone 1 between the spring pressure rod 5 and the base 3 .

[0081] A flexible sheath 5-4 is provided on one end of the pressure rod 5-3. Under the action of the spring 5-2, the flexible sheath 5-4 can abut against the first earphone shell of the earphone 1, so that the earphone 1 can be clamped between the spring pressure rod 5 and the base 3-1.

[0082] The flexible sheath 5-4 is made of Teflon material. The flexible sheath 5-4 is helpful to prevent the earphone 1 from being damaged when the earphone 1 is clamped. The flexible sheath 5-4 is also helpful to increase the friction between the flexible sheath 5-4 and the earphone 1 when the earphone 1 is clamped, so as to help keep the earphone in place stably when the earphone is clamped, and prevent the spring pressure rod 5 from sliding on the earphone 1.

[0083] Since the pressure rod 5-3 is slidably engaged with the pressure rod housing 5-1, earphones 1 with different sizes can be clamped between the spring pressure rod 5 and the base 3-1.

[0084] According to another embodiment of the present disclosure, a base recess 3-2 is further provided in the base 3-1. A flexible pad 7 is provided in the base recess 3-2. By rotating the spring pressure rod 5, the flexible sheath 5-4 can be pressed against the first earphone housing 1-1 of the earphone 1, so that the earphone 1 can be clamped between the spring pressure rod 5 and the flexible pad 7.

[0085] The flexible pad 7 is made of Teflon material and is helpful to prevent the earphone 1 from being damaged when the earphone 1 is clamped.

[0086] The flexible pad 7 is provided with a pad holding recess 7-1, in which the second earphone housing 1-2 of the earphone 1 can be held. The shape of the pad holding recess 7-1 is consistent with the outer contour of the second earphone housing of the earphone (that is, the cavity formed by the pad holding recess 7-1 can be different according to the different contours of the earphone, so as to be suitable for earphones of different models), so as to help stably hold the earphone 1 in place when clamping the earphone 1 and prevent the earphone 1 from moving on the flexible pad 7.

[0087] A magnetic attraction component (such as a magnet) is also provided in the base recess 3-2, which is used to absorb the flexible pad 7 (for example, by an iron block provided in the flexible pad 7) in the base recess 3-2, thereby facilitating the rapid installation and removal of the flexible pad 7.

[0088] like Figure 7 and Figure 8 As shown, according to another embodiment of the present disclosure, an earphone adhesive curing device 8 is disclosed. The earphone adhesive curing device 8 comprises a clamping device 2 as described in the above-mentioned embodiments. The clamping device 2 can clamp a plurality of earphones 1 therein.

[0089] The earphone adhesive curing device 8 further comprises a conveying device 9, which is configured to transport a plurality of the clamping devices into the interior of the earphone adhesive curing device 8.

[0090] An ultraviolet light source 10 is arranged inside the earphone adhesive curing device 8 .

[0091] The ultraviolet light sources 10 on both sides of the open space of the clamping device 2 simultaneously illuminate the earphone 1 clamped on the clamping device 2 through the open space, that is, the ultraviolet light source 10 can simultaneously illuminate the earphone 1 from the ear side and the outer side of the ear (the left and right sides) of the earphone.

[0092] The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the embodiments to the precise forms disclosed. Modifications and variations may be made in light of the above disclosure or may be acquired from practice of the embodiments.

[0093] Even though particular combinations of features are recited in the claims and / or disclosed in the specification, these combinations are not intended to limit the disclosure of the various embodiments. In fact, many of these features may be combined in ways not specifically recited in the claims and / or disclosed in the specification. Although each dependent claim listed below may only directly depend on one claim, the disclosure of the various embodiments includes each dependent claim in combination with every other claim in the claim set.
