The following is a more detailed description of the specific implementation of this utility model in conjunction with specific embodiments:

[0043] like Figures 1 to 3 As shown, a watch case fixing fixture 100 provided by an embodiment of the present invention is applied to the field of watch manufacturing, wherein the watches include but are not limited to mechanical watches and smart watches; the watch 200 includes a watch case 201 and a light-transmitting structure 202 (such as glass) fixed on the watch case 201, and the light-transmitting structure 202 is used to cover the watch case 201. The existing light-transmitting structure 202 is generally fixed to the watch case 201 by gluing. Specifically, glue is applied to the circumferential part of the watch case 201, and then the light-transmitting structure 202 is covered on the glue-applied part to achieve the fixation of the two; the watch case fixing fixture 100 provided in this embodiment has the effect of reducing the possibility of displacement of the watch case 201, improving the stability of the watch case 201 when it is fixed, and thereby improving the accuracy of the gluing operation and the fixing operation; the following is an explanation through a specific implementation method:

[0044] The watch case fixing fixture 100 includes:

[0045] A first plate body 1, a limiting platform 2 provided on the first plate body 1 for supporting the main body of the watch case 201, a plurality of limiting grooves 3 of the first protruding structure 2011 for accommodating the watch case 201, and a plurality of first limiting columns 4 for limiting the main body of the watch case 201, the limiting platform 2 is provided with a contact surface 21 abutting against the watch case 201, the limiting groove 3 is arranged adjacent to the limiting platform 2, a plurality of first limiting columns 4 are arranged in sequence along the circumference of the limiting platform 2, the contact surface 21 defines a first direction and a second direction perpendicular to the first direction, at least two first limiting columns 4 are arranged in sequence along the first direction, and at least two first limiting columns 4 are arranged in sequence along the second direction.

[0046] Here, it can be understood that the first plate body 1 refers to a plate structure for supporting the watch case 201;

[0047] The limiting platform 2 is a structure for supporting the watch case 201 and limiting the movement of the watch case 201 in one direction. Specifically, the limiting platform 2 has an abutting surface 21. When the watch case 201 is placed on the limiting platform 2, the bottom surface of the main body of the watch case 201 abuts against the abutting surface 21. The abutting surface 21 is a surface that matches the bottom surface of the watch case 201. In this way, when the abutting surface 21 is vertically upward, the abutting surface 21 can support the watch case 201, which is equivalent to limiting the movement of the watch case 201 in the vertical direction.

[0048] The limiting groove 3 refers to a groove structure for accommodating the first protruding structure 2011 of the watch case 201; the limiting groove 3 is provided on the first plate 1, and the shape and size of the limiting groove 3 just match the shape and size of the first protruding structure 2011 of the watch case 201, so that the first protruding structure 2011 can be just accommodated in the limiting groove 3 when the watch case 201 is placed on the limiting platform 2; the groove wall of the limiting groove 3 can limit the movement of the first protruding structure 2011, and thus limit the movement of the entire watch case 201; in this embodiment, the first protruding structure 2011 is the connecting portion (lug) between the watch case 201 and the watch strap; the limiting groove 3 is arranged adjacent to the limiting platform 2, corresponding to the main body and the lug of the watch case 201, respectively;

[0049] The first limiting column 4 refers to a columnar structure used to limit the movement of the main body of the watch case 201; the first limiting column 4 is protruded on the first plate body 1, wherein a plurality of first limiting columns 4 are arranged in sequence along the circumference of the limiting platform 2, wherein the abutting surface 21 defines a first direction and a second direction, the second direction is perpendicular to the first direction, and the first direction and the second direction are parallel to the abutting surface 21, and at least two first limiting columns 4 are arranged in sequence along the first direction, so that the main body of the watch case 201 is blocked by the first limiting column 4 in the first direction. Since the second direction is perpendicular to the first direction, the first limiting column 4 can limit the movement of the main body of the watch case 201 in the second direction; similarly, at least two first limiting columns 4 are arranged in sequence along the second direction, so that the main body of the watch case 201 is blocked by the first limiting column 4 in the second direction. Since the first direction is perpendicular to the second direction, the first limiting column 4 can limit the movement of the main body of the watch case 201 in the first direction.

[0050] The working principle of the watch case fixing fixture 100 provided in this embodiment is as follows:

[0051] Place the first plate 1 horizontally, wherein the abutting surface 21 of the limiting platform 2 is parallel to the horizontal plane, and place the watch case 201 on the limiting platform 2, wherein the abutting surface 21 abuts against the bottom surface of the main body of the watch case 201, so that the abutting surface 21 supports the main body of the watch case 201 and limits the movement of the watch case 201 in the vertical direction, that is, limits the movement in the Z-axis direction; the first protruding structure 2011 of the watch case 201 is correspondingly accommodated in the limiting groove 3, and the groove wall of the limiting groove 3 is used to limit the first protruding structure 20 11's movement; since the first limiting posts 4 are arranged in sequence along the circumference of the limiting platform 2, the first limiting posts 4 abut against the main body of the watch case 201, and are used to limit the main body of the watch case 201, and since at least two first limiting posts 4 are arranged along the first direction, and at least two first limiting posts 4 are arranged along the second direction, a plurality of first limiting posts 4 respectively limit the movement of the main body of the watch case 201 in the first direction and the second direction, that is, limit the movement of the watch case 201 in the X-axis direction and the Y-axis direction.

[0052] By adopting the above-mentioned technical solution, a plurality of limiting grooves 3 are provided on the first plate body 1 to correspond to the lugs on the watch case 201, so that the abutting surface 21 on the limiting ring table can abut against the bottom surface of the main body of the watch case 201, and thus the entire watch case 201 can be placed horizontally on the watch case fixing jig 100, thereby limiting the movement of the watch case 201 in the vertical direction; at the same time, a plurality of first limiting columns 4 are provided on the first plate body 1 to limit the movement of the watch case 201 in the first direction and the second direction, so that the watch case fixing jig 100 limits the movement of the watch case 201 in the X-axis direction, the Y-axis direction and the Z-axis direction, thereby improving the stability of the watch case 201 fixed on the watch case fixing jig 100, and improving the accuracy and dispensing effect of the dispensing operation.

[0053] In one embodiment, the limiting groove 3 is located between two adjacent first limiting columns 4 .

[0054] Here, it can be understood that when the first protruding structure 2011 is a watch lug, the position of the watch lug is adapted to the position of the watch strap. The watch case 201 includes two groups of watch lugs, each group of watch lugs includes two symmetrically arranged watch lugs, and the first limiting column 4 is used to limit the main body of the watch case 201. The limiting groove 3 is set between two adjacent first limiting columns 4, so as to avoid the first limiting column 4 blocking the first protruding structure 2011 from being accommodated in the limiting groove 3.

[0055] By adopting the above technical solution, the degree of fit between the watch case fixing fixture 100 and the watch case 201 is improved.

[0056] In one embodiment, the limiting groove 3 includes a first limiting groove section 31 and a second limiting groove section 32. The limiting sizes of the first limiting groove section 31 and the second limiting groove section 32 are different. The first limiting groove section 31 is used to limit the first protruding structure 2011 of the first size. The first limiting groove 3 is located between two adjacent first limiting columns 4 in the first direction. The second limiting groove section 32 is used to limit the first protruding structure 2011 of the second size. The second limiting groove 3 is located between two adjacent first limiting columns 4 in the second direction.

[0057] Here, it can be understood that the sizes of the first protruding structures 2011 of different watch cases 201 are different. In this embodiment, the limiting groove 3 can adapt to the use of two first protruding structures 2011 of different sizes; specifically, the limiting groove 3 includes a first limiting groove section 31 and a second limiting groove section 32, the first limiting groove section 31 is used to limit the first protruding structure 2011 of the first size, and the second limiting groove section 32 is used to limit the second protruding structure of the second size, the first limiting groove section 31 and the second limiting groove section 32 are respectively located in the first direction and the second direction, that is, the first limiting groove section 31 is located between two adjacent first limiting columns 4 in the first direction, and the second limiting groove section 32 is located between two adjacent second limiting columns in the first direction; in this way, the watch case 201 can adjust the direction in which it is placed on the limiting platform 2 to adjust its own first protruding structure 2011 to be clamped into different limiting groove 3 sections.

[0058] By adopting the above technical solution, the applicability of the watch case fixing fixture 100 is improved.

[0059] In one embodiment, the case fixing jig 100 also includes a second limiting column 5 for interfering with the second protruding structure 2012 of the case 201. The second limiting column 5 is located circumferentially on the limiting platform 2. Two adjacent first limiting columns 4 form a group of first limiting columns 4. A second limiting column 5 is provided between at least one group of adjacent first limiting columns 4.

[0060] Here, it can be understood that the second limiting post 5 is used to interfere with the second protruding structure 2012 on the watch case 201, so that the watch case fixing fixture 100 has an anti-foolproof design; in this embodiment, the second protruding structure 2012 is a crown, and the crown is located on one side of the main body of the watch case 201. Since the watch case 201 is placed on the watch case fixing fixture 100, the watch case 201 needs to be placed on the limiting platform 2 in a specified direction, and the second limiting post 5 is set at the position of the crown corresponding to the first plate 1. When the watch case 201 is placed on the limiting platform 2 in the wrong direction, the second limiting post 5 just interferes with the crown, resulting in the bottom surface of the watch case 201 being unable to fit with the abutment surface 21. In this way, the second limiting post 5 plays an anti-foolproof role, that is, only when the watch case 201 is placed on the watch case fixing fixture 100 in the correct direction, the second limiting post 5 will not interfere with the second protruding structure 2012, and the bottom surface of the main body of the watch case 201 can fit with the abutment surface 21.

[0061] By adopting the above technical solution, the watch case fixing fixture 100 has a fool-proof design, thereby improving the accuracy and efficiency of fixing the watch case 201.

[0062] In one embodiment, the first limiting column 4 and the second limiting column 5 are protruded from the surface of the first plate 1 , the protruding portion of the first limiting column 4 is provided with a first guide structure 41 , and the protruding portion of the second limiting column 5 is provided with a second guide structure 51 .

[0063] Here, it can be understood that the first guide structure 41 is tapered from the side away from the first plate body 1 along the direction approaching the first plate body 1. Similarly, the second guide structure 51 is tapered from the side away from the first plate body 1 along the direction approaching the first plate body 1. In this way, when the watch case 201 is placed on the limit platform 2, the first guide structure 41 and the second guide structure 51 can guide the watch case 201 to be placed on the limit platform 2.

[0064] By adopting the above technical solution, the efficiency of placing the watch case 201 on the limiting platform 2 is improved.

[0065] In one embodiment, the first plate body 1 is provided with an opening 11 penetrating the first plate body 1 , and the limiting platform 2 is disposed around the opening 11 .

[0066] Here, it can be understood that the opening 11 is used for the robot to extend into the watch case 201 located on the first plate 1 , so that the robot can further assemble the watch case 201 .

[0067] By adopting the above technical solution, the opening 11 is opened in the first plate body 1, thereby increasing the operating space and improving the flexibility of assembly.

[0068] Please also refer to Figure 4 In one embodiment, the watch case fixing fixture 100 also includes a second plate 6 for pressing the light-transmitting structure 202 onto the watch case 201 and a connecting structure 7 connecting the second plate 6 and the first plate 1. The connecting structure 7 includes a hook member 71 and a hook groove 72 that cooperates with the hook member 71. The hook member 71 is provided on the first plate 1, and the hook groove 72 is provided on the second plate 6.

[0069] Here, it can be understood that the case fixing jig 100 has the functions of dispensing glue and maintaining pressure; specifically, the case fixing jig 100 also includes a second plate 6 and a connecting structure 7, wherein the second plate 6 is used to press the light-transmitting structure 202 (for example, glass) onto the case 201, and the second plate 6 is arranged parallel to and spaced apart from the first plate 1, and the connecting structure 7 includes a hook member 71 and a hook groove 72, the hook member 71 is provided on the first plate 1, and the hook groove 72 is opened on the second plate 6, the hook member 71 can be inserted into the hook groove 72 to realize the connection between the first plate 1 and the second plate 6, and at the same time, the cooperation between the hook member 71 and the hook groove 72 makes the second plate 6 pressed tightly against the first plate 1, and then the light-transmitting structure 202 is pressed tightly against the case 201, so that after the case 201 is dispensed with glue, the light-transmitting structure 202 is pressed tightly against the case 201 to achieve bonding between the two.

[0070] By adopting the above technical solution, the functionality of the watch case fixing fixture 100 is improved.

[0071] See also Figure 5 and Figure 6 In one embodiment, the hook groove 72 is provided with a hook wall 721, and the hook member 71 is provided with a hook surface 711 that abuts against the hook wall 721. The hook surface 711 is inclined relative to the hook wall 721, so that any part of the hook surface 711 in the inclined direction can abut against the hook wall 721.

[0072] Here, it can be understood that each hook member 71 has a length error. Therefore, there may be a gap when the hook member 71 cooperates with the hook groove 72, which makes it possible that a large gap may exist in a certain area between the first plate body 1 and the second plate body 6. The above design can make the hook surface 711 and the hook wall 721 always abut against each other, ensuring that the hook member 71 always applies force on the hook groove 72, reducing the possibility of a large gap between the first plate body 1 and the second plate body 6.

[0073] By adopting the above technical solution, the possibility of a large gap between the first plate body 1 and the second plate body 6 is reduced, and the reliability during pressure maintenance is improved.

[0074] In one embodiment, the second plate body 6 is provided with a hook block 61, and a hook groove 72 is provided on the hook block 61. The hook block 61 is elastically connected to the second plate body 6. The hook block 61 is used to drive the hook groove 72 to face or stagger with the hook member 71. The hook member 71 is inserted into the hook groove 72 when the hook groove 72 faces the hook member 71.

[0075] By adopting the above technical solution, the function of connecting and unlocking the first plate body 1 and the second plate body 6 by the connecting structure 7 is realized.

[0076] Please refer again Figure 4 In one embodiment, the second plate body 6 is provided with a fixing groove 62 that matches the light-transmitting structure 202, wherein the groove wall of the fixing groove 62 is provided with a soft structure 63, such as a silicone pad, so that when the second plate body 6 maintains pressure on the light-transmitting structure 202, the possibility of scratching the light-transmitting structure 202 is reduced; a plurality of soft structures 63 are arranged in sequence on the groove wall of the fixing groove 62 in the circumferential direction, so that the soft structure 63 separates the light-transmitting structure 202 and the groove wall of the fixing groove 62 by a preset distance, further reducing the risk of the light-transmitting structure 202 being scratched.

[0077] In a second aspect, a glue dispensing device for a watch 200 is provided, comprising a glue dispensing device and the above-mentioned watch case fixing fixture 100 , wherein the glue dispensing device is used for glue dispensing the watch case 201 located on the watch case fixing fixture 100 .
