[0054] Currently, TWS earphones have very high dimensional process requirements. However, during assembly, without dedicated adjustment equipment and without matching the dimensions of the components, TWS earphones are required to achieve a step size CPK>1.33. However, TWS earphone components are usually suspended in the housing. During assembly, the components often fall below the housing surface, making it impossible to ensure that the components sink, resulting in failure to meet product dimensional requirements. After assembly, due to the lack of pre-fixation during pressure holding, the dimensional data is too scattered, and CPK<1.33, resulting in a very low product yield.

[0055] Based on the above concepts and problems, the present invention proposes a pre-fixing jig 100. The pre-fixing jig 100 is used for product assembly, such as TWS earphone products. It can be understood that the TWS earphone product includes a movable part 5 and a fixed part 6, and the fixed part 6 is provided with a receiving groove 61. During the assembly process, it is necessary to assemble and fix the movable part 5 in the receiving groove 61 of the fixed part 6, and ensure that the movable part 5 does not sink or fall below the end face of the fixed part 6 after being assembled in the receiving groove 61 of the fixed part 6, so as to meet the product size requirements and improve the product yield.

[0056] It is understood that the receiving groove 61 of the fixed component 6 is a groove structure with one end open. The material of the fixed component 6 can be the same as or different from the material of the movable component 5. Optionally, the fixed component 6 and the movable component 5 can be injection molded using a plastic material. Of course, the fixed component 6 and the movable component 5 can also be formed using a metal material.

[0057] Please refer to Figures 1 to 4 As shown, in an embodiment of the present invention, the pre-fixing jig 100 is used for pre-fixing the movable part 5 and the fixed part 6, the fixed part 6 is provided with a receiving groove 61, the pre-fixing jig 100 includes a jig body 1 and an adsorption member 2, the jig body 1 has a positioning surface 11, and a positioning portion 3 is convexly provided on the side of the jig body 1 facing the positioning surface 11, the positioning portion 3 is arranged at an angle to the positioning surface 11, the positioning portion 3 is used to abut against the outer wall of the fixed part 6 for positioning, the adsorption member 2 is provided with a positioning surface 11, and is spaced from the positioning portion 3, the adsorption member 2 is used to adsorb and fix the movable part 5; wherein, the movable part 5 has a first position in which it is movably accommodated in the receiving groove 61 and a second position in which it is pre-fixed in the receiving groove 61; in the second position, the positioning surface 11 is limitedly abutted against the end face of the notch of the receiving groove 61, and the adsorption member 2 adsorbs and fixes the movable part 5, so that the movable part 5 is pre-fixed in the receiving groove 61.

[0058] In this embodiment, the fixture body 1 of the pre-fixed fixture 100 includes a limiting portion and a positioning portion 3 arranged at an angle, and the surface of the limiting portion facing the positioning portion 3 forms a positioning surface 11, that is, the positioning portion 3 is arranged at an angle to the positioning surface 11. It can be understood that the positioning portion 3 is located at the edge of the positioning surface 11. The angle formed by the positioning portion 3 and the positioning surface 11 is greater than 0° and less than 180°. Optionally, the angle formed by the positioning portion 3 and the positioning surface 11 is 30°, 45°, 60°, 80°, 90°, 100°, 120°, 150°, etc., which is not limited here.

[0059] It should be noted that the angle between the positioning portion 3 and the positioning surface 11 is specifically determined based on the shape of the fixing component of the preassembled product and is not limited here. In this embodiment, the angle formed by the positioning portion 3 and the positioning surface 11 can be selected to be 90°, that is, the surface of the end of the fixing component 6 having the notch of the receiving groove 61 is perpendicular to the surface of the outer wall.

[0060] It is understandable that the fixture body 1 can be made of metal material processing or stamping, or can be made of plastic material injection molding, which is not limited here. In this embodiment, by setting the adsorption member 2 on the positioning surface 11 of the fixture body 1, the adsorption member 2 is used to adsorb and fix the movable part 5.

[0061] It should be noted that the movable component 5 and the fixed component 6 are separate components. When the movable component 5 is assembled in the receiving groove 61 of the fixed component 6, the product has an unassembled state in which the movable component 5 is movably received in the receiving groove 61, and an assembled state in which the movable component 5 is pre-fixed or fixed in the receiving groove 61. It will be understood that in the unassembled state, the movable component 5 is movably received in the first position in the receiving groove 61, and in the assembled state, the movable component 5 is fixed in the second position in the receiving groove 61.

[0062] In this embodiment, when the movable component 5 and the fixed component 6 are pre-assembled using the pre-fixing fixture 100, the positioning surface 11 of the pre-fixing fixture 100 is limitedly abutted against the end face of the notch of the accommodating groove 61, and the adsorption component 2 adsorbs and fixes the movable component 5 so that the movable component 5 is in the second position in the accommodating groove 61, so as to realize the pre-fixation of the movable component 5 in the accommodating groove 61, and then the subsequent fixed assembly steps are performed, thereby ensuring that the movable component 5 is fixed in the second position in the accommodating groove 61 after assembly and fixation, and the movable component 5 will not sink into the accommodating groove 61 of the fixed component 6 or the end faces of the notches of the movable component 5 and the accommodating groove 61 of the fixed component 6 will not be aligned.

[0063] The pre-fixed jig 100 of the present invention is provided with a positioning portion 3 and a positioning surface 11 set at an angle on the jig body 1, and the positioning portion 3 and the positioning surface 11 cooperate with the outer wall of the fixed component 6 and the end face of the notch of the accommodating groove 61 to limit the position, and an adsorption component 2 is provided on the positioning surface 11, and the adsorption component 2 is used to adsorb and fix the movable component 5, so that when the positioning surface 11 of the jig body 1 is limitedly abutted with the end face of the notch of the accommodating groove 61, the adsorption component 2 is used to adsorb and fix the movable component 5, so as to ensure that the movable component 5 is pre-fixed in the position in the accommodating groove 61, and effectively avoid the problem of the movable component 5 sinking or being lower than the surface of the fixed component 6 after the assembly is completed, thereby effectively ensuring the yield of the assembled product and meeting the product size requirements.

[0064] It is understood that the positioning surface 11 abuts against the end surface of the notch of the accommodating groove 61 to ensure that the movable component 5 is fixed by the adsorption member 2, and the movable component 5 can be aligned with the end surface of the notch of the accommodating groove 61 or the step difference can be reduced. In this embodiment, at least a portion of the positioning surface 11 is suspended outside the fixed component 6, that is, the area of ​​the positioning surface 11 projected onto the horizontal plane is larger than the area of ​​the notch end surface of the accommodating groove 61 projected onto the horizontal plane.

[0065] In one embodiment, the adsorption member 2 may be a magnetic member, such as a magnet, an electromagnet, a suction cup, or other structures having an adsorption and fixing function, which are not limited here.

[0066] Optionally, when the movable part 5 is made of metal, the adsorption part 2 can be a magnetic part, such as a magnet. Figure 3 and Figure 4 As shown, a magnetic member 51 such as a magnet may be provided in the movable part 5 . In this case, the adsorption member 2 and the magnetic member 51 in the movable part 5 are adsorbed and fixed to each other.

[0067] It can be understood that by adding a contoured magnet to the positioning surface 11 and adding an iron block to the movable part 5, the suspended movable part 5 is sucked onto the flat positioning surface 11 by using the magnetic attraction, the positioning surface 11 is fixed to the fixture body 1, and the movable part 5 is pre-fixed by using the magnetic attraction. After the glue between the movable part 5 and the fixed part 6 is cured at the pre-fixed position, the movable part 5 is fixed to complete the assembly of the product.

[0068] In one embodiment, the positioning surface 11 is provided with a mounting groove, and the adsorption member 2 is fixed in the mounting groove. It can be understood that by fixing the adsorption member 2 to the mounting groove of the positioning surface 11, the adsorption and fixing stability between the adsorption member 2 and the movable component 5 is ensured.

[0069] Optionally, the adsorption member 2 is flush with the positioning surface 11. Of course, the adsorption member 2 can also protrude from the positioning surface 11. In this case, a groove 52 is formed on the movable part 5. The adsorption member 2 protruding from the positioning surface 11 extends into the groove 52 to adsorb and fix the movable part 5, so that the surface of the movable part 5 abuts the positioning surface 11. When the positioning surface 11 abuts the end surface of the notch of the accommodating groove 61, the surface of the movable part 5 is flattened to the end surface of the notch of the accommodating groove 61.

[0070] To adjust the relative position of the adsorption member 2 and the positioning surface 11, the adsorption member 2 can also be configured as an adjustable structure or a movable connection structure. In one embodiment, the fixture body 1 is provided with a mounting hole 12 that passes through the positioning surface 11. The pre-fixed fixture 100 also includes an adjustment member provided on the fixture body 1. The adsorption member 2 is movably provided in the mounting hole 12 and is movably connected to the adjustment member. The adjustment member is used to adjust the height of the adsorption member 2 protruding from the positioning surface 11.

[0071] Understandably, Figure 1 、 Figure 3 and Figure 4 As shown, the adsorption member 2 is movably inserted into the mounting hole 12 and the adsorption member 2 is fixed or adjusted by the adjusting member, so that the height of the adsorption member 2 protruding from the positioning surface 11 is adjusted by the adjusting member.

[0072] It should be noted that whether the adsorption member 2 protrudes from the surface of the positioning surface 11 and the height of the protrusion are specifically set according to the external structure of the pre-assembled movable component 5 and are not limited here.

[0073] In one embodiment, the adjusting member is an adjusting screw, one end of which is movably connected to the adsorption member 2 , so that the height of the adsorption member 2 protruding from the positioning surface 11 can be adjusted by the adjusting screw.

[0074] In another embodiment, the outer wall of the adsorption member 2 is provided with a plurality of card slots, and the plurality of card slots are extended along the extension direction of the adsorption member 2. The adjustment member is an adjustment pin provided on the side of the fixture body 1 facing away from the positioning surface 11. The adsorption member 2 is movably inserted into the mounting hole 12, and the adjustment pin is detachably engaged in a card slot.

[0075] In another embodiment, a screw is provided on the side of the adsorption member 2 facing away from the positioning surface 11, the adjustment member is a bracket, the bracket is provided with a screw hole, the end of the screw away from the adsorption member 2 is passed through the screw hole and is screwed to the bracket.

[0076] Of course, the matching structure between the adjusting member and the adsorption member 2 may also be other structures capable of adjusting the height of the adsorption member 2 protruding from the positioning surface 11, which is not limited here.

[0077] In one embodiment, the outer wall of the adsorption member 2 is further provided with a scale, which is provided along the extension direction of the adsorption member 2. It can be understood that by providing a scale on the adsorption member 2, when adjusting the height of the adsorption member 2 protruding from the positioning surface 11, the adjustment can be displayed by the scale, thereby improving convenience.

[0078] In one embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, the side of the fixture body 1 away from the positioning portion 3 is further provided with an avoidance area 13, which is used to avoid the structure of the movable part 5 or the fixed part 6. It is understandable that the avoidance area 13 can be a structure such as an avoidance groove, a through groove or a notch, which is not limited here.

[0079] In one embodiment, if Figures 1 to 4 As shown, the fixture body 1 is further provided with a hollow area 14 penetrating the positioning surface 11 , and includes a plurality of adsorption members 2 , which are provided on the positioning surface 11 and symmetrically arranged on opposite sides of the hollow area 14 .

[0080] It can be understood that the hollow area 14 passes through the middle of the limiting part to separate the positioning surface 11 into two symmetrically arranged parts. By setting multiple adsorption parts 2, multiple adsorption parts 2 are arranged on the positioning surface 11 and symmetrically arranged on the opposite sides of the hollow area 14, thereby improving the stability of the adsorption parts 2 in adsorbing and fixing the movable parts 5.

[0081] In one embodiment, if Figures 1 to 4 As shown, the pre-fixing jig 100 further includes a positioning pin 4 provided on the edge of the positioning surface 11, and the positioning pin 4 is used to positionally connect with the jig on which the fixed component 6 is placed. It can be understood that by providing the positioning pin 4, when the pre-fixing jig 100 pre-fixes the movable component 5 and the fixed component 6, the pre-fixing jig 100 is positioned and connected with the jig on which the fixed component 6 is placed via the positioning pin 4, thereby avoiding the situation where the position of the adsorption member 2 adsorbing and fixing the movable component 5 is damaged when the pre-fixing jig 100 is collided with, causing the pre-fixing position of the movable component 5 in the receiving groove 61 to change.

[0082] The present invention also proposes an assembly method using the above-mentioned pre-fixing fixture 100. The specific structure of the pre-fixing fixture 100 refers to the aforementioned embodiment. Since this assembly method adopts all the technical solutions of all the aforementioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the aforementioned embodiments, which will not be described one by one here.

[0083] In this embodiment, the assembly method includes:

[0084] A fixed component 6 and a movable component 5 are provided, wherein the fixed component 6 has a receiving groove 61 for mounting and fixing the movable component 5;

[0085] Place the fixture body 1 of the pre-fixed fixture 100 in the notch of the receiving groove 61 of the fixing member 6, so that the positioning portion 3 of the fixture body 1 abuts against the outer wall of the fixing member 6, and the positioning surface 11 of the fixture body 1 abuts against the end surface of the notch of the receiving groove 61;

[0086] The adsorption member 2 of the pre-fixing jig 100 adsorbs and fixes the movable component 5 , so that the movable component 5 is pre-fixed in the receiving groove 61 .

[0087] It can be understood that the fixed component 6 and the movable component 5 are two independent components. The movable component 5 needs to be assembled and fixed in the receiving groove 61 of the fixed component 6, and ensure that the movable component 5 does not sink or fall below the end face of the fixed component 6 after being assembled in the receiving groove 61 of the fixed component 6, so as to meet the product size requirements and improve the product yield.

[0088] In this embodiment, the fixed component 6 has a receiving groove 61 for mounting and securing the movable component 5. The receiving groove 61 of the fixed component 6 is a recessed groove structure with one end open. It is understood that the material of the fixed component 6 and the movable component 5 can be the same or different. Optionally, the fixed component 6 and the movable component 5 can be injection molded from a plastic material. Of course, the fixed component 6 and the movable component 5 can also be formed from a metal material.

[0089] It should be noted that, taking the charging case of a TWS headset as an example, the fixed component 6 is the outer shell of the charging case, and the movable component 5 is the supporting component assembled within the outer shell for supporting the headset. Typically, when the supporting component is assembled within the receiving groove 61 of the outer shell, the supporting component is suspended within the receiving groove 61.

[0090] In order to ensure that the supporting component does not sink into the receiving groove 61 of the shell after assembly or the surface of the supporting component is lower than the end face of the notch of the receiving groove 61, in this embodiment, the supporting component and the shell are pre-fixed and assembled by using a pre-fixing fixture 100 to ensure the accuracy of the pre-fixing position, thereby ensuring the yield of the product.

[0091] In this embodiment, when the jig body 1 is placed in the notch of the receiving groove 61 of the fixed component 6, the positioning portion 3 of the jig body 1 abuts against the outer wall of the fixed component 6, and the positioning surface 11 of the jig body 1 abuts against the end face of the notch of the receiving groove 61, so as to utilize the positioning portion 3 and the positioning surface 11 to ensure the position of the pre-fixed jig 100 relative to the end face of the notch of the receiving groove 61 of the fixed component 6, and then utilize the adsorption component 2 to adsorb and fix the movable component 5, so as to ensure that the position of the movable component 5 pre-fixed in the receiving groove 61 does not change, and to ensure that the movable component 5 does not sink into the receiving groove 61 of the outer shell or the surface of the movable component 5 is lower than the end face of the notch of the receiving groove 61.

[0092] In one embodiment, before the step of placing the fixture body 1 of the pre-fixing fixture 100 in the notch of the receiving groove 61 of the fixing component 6, the method further includes:

[0093] Place the movable component 5 in the receiving groove 61 so that the movable component 5 is in the first position in the receiving groove 61;

[0094] The steps of adsorbing and fixing the movable component 5 by the adsorption member 2 of the pre-fixing fixture 100 so as to pre-fix the movable component 5 in the receiving groove 61 include:

[0095] The adsorption member 2 adsorbs the movable component 5 to adjust the position of the movable component 5 in the receiving groove 61 , so that the movable component 5 is pre-fixed at the second position in the receiving groove 61 .

[0096] It can be understood that when the movable part 5 is assembled in the receiving groove 61 of the fixed part 6, the movable part 5 and the receiving groove 61 of the fixed part 6 are first glued, and the movable part 5 is placed in the receiving groove 61 so that the movable part 5 is in the first position in the receiving groove 61. Then, the pre-fixing fixture 100 is used to make the fixture body 1 placed in the notch of the receiving groove 61 of the fixed part 6. The positioning portion 3 of the fixture body 1 abuts against the outer wall of the fixed part 6, and the positioning surface 11 of the fixture body 1 abuts against the end face of the notch of the receiving groove 61, so as to utilize the positioning portion 3 and the positioning surface 11 to ensure the position of the pre-fixing fixture 100 relative to the end face of the notch of the receiving groove 61 of the fixed part 6, and then the adsorption part 2 is used to adsorb and fix the movable part 5 to ensure that the position of the movable part 5 pre-fixed in the receiving groove 61 does not change, and to ensure that the movable part 5 does not sink into the receiving groove 61 of the shell or the surface of the movable part 5 is lower than the end face of the notch of the receiving groove 61.

[0097] In another embodiment, before the step of placing the fixture body 1 of the pre-fixing fixture 100 in the notch of the receiving groove 61 of the fixing component 6, the method further includes:

[0098] The adsorption member 2 adsorbs and fixes the movable component 5;

[0099] The steps of placing the fixture body 1 of the pre-fixing fixture 100 in the notch of the receiving groove 61 of the fixing component 6 so that the positioning portion 3 of the fixture body 1 abuts against the outer wall of the fixing component 6 and the positioning surface 11 of the fixture body 1 abuts against the end surface of the notch of the receiving groove 61; and the adsorption part 2 of the pre-fixing fixture 100 adsorbs and fixes the movable component 5 so that the movable component 5 is pre-fixed in the receiving groove 61 include:

[0100] The pre-fixing fixture 100 drives the movable component 5 to extend into the accommodating groove 61 through the notch of the accommodating groove 61;

[0101] Place the jig body 1 of the pre-fixed jig 100 in the notch of the receiving groove 61 of the fixed component 6, so that the positioning portion 3 of the jig body 1 abuts against the outer wall of the fixed component 6, and the positioning surface 11 of the jig body 1 abuts against the end face of the notch of the receiving groove 61, so that the movable component 5 is pre-fixed in the receiving groove 61.

[0102] It is understandable that when the movable component 5 is assembled in the receiving groove 61 of the fixed component 6, glue is first applied to the movable component 5 and the receiving groove 61 of the fixed component 6. Then, the adsorption part 2 of the pre-fixing jig 100 is used to adsorb and fix the movable component 5, and then the pre-fixing jig 100 and the movable component 5 are placed together in the notch of the receiving groove 61 of the fixed component 6. At this time, the pre-fixing jig 100 drives the movable component 5 through the notch of the receiving groove 61 and extends into the receiving groove 61, so that the positioning portion 3 of the jig body 1 abuts the outer wall of the fixed component 6, and the positioning surface 11 of the jig body 1 abuts the end face of the notch of the receiving groove 61, thereby ensuring that the movable component 5 is pre-fixed at the second position in the receiving groove 61.

[0103] In one embodiment, after the step of the adsorption member 2 of the pre-fixing jig 100 adsorbing and fixing the movable component 5 so that the movable component 5 is pre-fixed in the receiving groove 61, the step further includes:

[0104] Glue is applied between the movable component 5 and the wall of the accommodating groove 61 to form an adhesive layer, and the adhesive layer is fixed so that the movable component 5 is fixed to the wall of the accommodating groove 61 .

[0105] It can be understood that by dispensing glue on the movable component 5 and the groove wall of the accommodating groove 61 to form a glue layer, when the movable component 5 is pre-fixed at the second position in the accommodating groove 61, after the glue layer is fixed, the movable component 5 can be fixed to the groove wall in the accommodating groove 61, and then the pre-fixing fixture 100 can be removed to complete the assembly.

[0106] Of course, the step of applying glue between the movable part 5 and the wall of the accommodating groove 61 can also be placed before the step of placing the fixture body 1 of the pre-fixing fixture 100 in the notch of the accommodating groove 61 of the fixed part 6, which is not limited here.

[0107] The present invention also proposes an assembly device, which includes an assembly jig and the above-mentioned pre-fixing jig 100.

Since this assembly device adopts all the technical solutions of all the aforementioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the aforementioned embodiments, which will not be repeated here one by one.

[0108] In this embodiment, the assembly jig is provided with a placement groove for placing the fixing component 6. The pre-fixing jig 100 is placed at the end of the fixing component 6, and the positioning surface 11 of the pre-fixing jig 100 abuts against the end to limit the position. It can be understood that the placement groove is used to place and position the fixing component 6, and the placement groove can be a cavity structure such as a groove or channel.

[0109] It can be understood that in order to further position the pre-fixing jig 100 and the assembly jig, a positioning hole structure corresponding to the positioning pin 4 is provided on the assembly jig, so that the jig body 1 of the pre-fixing jig 100 is placed in the notch of the accommodating groove 61 of the fixing component 6, and the positioning pin 4 is movably positioned in the positioning hole of the assembly jig, and the positioning portion 3 of the jig body 1 is abutted against the outer wall of the fixing component 6, and the positioning surface 11 of the jig body 1 is limitedly abutted against the end face of the notch of the accommodating groove 61.
