Description

Technical Field

[0001] This utility model relates to the field of watch production equipment technology, and in particular to a bottom case disassembly fixture. Background Technology

[0002] During watch production and assembly, an airtightness test is required at the joint where the middle frame and the case back are bonded. If a poor airtightness is detected, the case back and middle frame must be disassembled for inspection and rework. Currently, the industry commonly uses manual disassembly to separate the case back and middle frame: the adhesive at the joint is softened by heating, and then a pry tool is used to gradually separate the case back and middle frame along the outer circumference of the middle frame. However, manual disassembly suffers from low efficiency and high labor costs. Summary of the Invention

[0003] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide a bottom case disassembly fixture that can quickly disassemble the bottom case and the middle frame, thereby improving watch production efficiency and reducing production costs.

[0004] This utility model is achieved through the following technical solution: a bottom case disassembly fixture for disassembling the middle frame and bottom case of a watch, including a base, a lifting driver, a pressure seat, and a push block; the base is provided with a through groove for receiving the middle frame and bottom case and supporting the middle frame, the pressure seat is located above the through groove and is disposed at the output end of the lifting driver, and the push block is used to place the bottom case; under the drive of the lifting driver, the pressure seat pushes the push block downward, pushing the bottom case away from the middle frame.

[0005] Compared with the prior art, the bottom shell disassembly fixture provided by this utility model can quickly disassemble the bottom shell and the middle frame by accommodating the bonded middle frame through the through groove and supporting the middle frame, and then placing the push block on the bottom shell. The push block can be pressed down by the lifting driver, thereby improving the watch production efficiency and reducing the production cost.

[0006] Furthermore, the push block includes a push block body for placement on the bottom shell, and a plurality of balance columns for being pressed against by the pressure seat; the balance columns are arranged vertically on the push block body. The design of the balance columns facilitates the placement and removal of the push block body and ensures that pressure is evenly transmitted to the push block body, preventing uneven force distribution on the push block body that could lead to deformation or damage to the bottom shell.

[0007] Furthermore, the pusher body includes a connecting portion for extending into the middle frame and an abutting portion for being placed inside the bottom shell; the connecting portion matches the inner contour of the middle frame, and the abutting portion matches the inner contour of the bottom shell; the balance column is connected to the abutting portion through the connecting portion. The design of the abutting portion ensures more even pressure distribution on the bottom shell, avoiding localized stress concentration and reducing the risk of damage. In addition, the design of the connecting portion and the abutting portion not only enables rapid alignment of the pusher body, facilitating its placement on the bottom shell, but also prevents tilting or displacement of the pusher body during pressure application.

[0008] Furthermore, it also includes an elastic element disposed on the pressure base, through which the pressure base presses against the balance column. The elastic element provides cushioning to prevent excessive pressure from damaging the bottom shell.

[0009] Furthermore, the pressure base has a mounting hole at the position corresponding to the balance column for the balance column to be inserted. The mounting hole matches the balance column, and the elastic element is disposed within the mounting hole. The design of the mounting hole ensures that the pressure on the balance column is always vertically downward.

[0010] Furthermore, the number of balancing columns is four, and the four balancing columns are arranged in an array on the push block body. The array arrangement helps to distribute the force evenly.

[0011] Furthermore, the through groove includes a main through groove for accommodating the middle frame and the bottom case, and a support boss; the support boss is disposed on both sides of the main through groove and is used to extend into the lug mounting cavity of the watch and abut against the middle frame. The support boss abuts against the middle frame to prevent the middle frame from shifting downwards.

[0012] Furthermore, the pressure seat has a plurality of guide posts or guide holes on the side facing the base, and the base has corresponding guide holes or guide posts on the side facing the pressure seat; the guide posts cooperate with the guide holes. The cooperation between the guide posts and guide holes ensures that the pressure seat will not deviate when moving.

[0013] Furthermore, a guide sleeve is provided inside the guide hole, and the guide hole cooperates with the guide post through the guide sleeve. The guide sleeve reduces wear and increases the life of the fixture.

[0014] Furthermore, the base is provided with openings for removing the middle frame. These openings are respectively located on both sides of the through groove and communicate with it. The openings facilitate the removal of the middle frame.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The bottom case disassembly fixture provided in this embodiment is mainly used to disassemble the middle frame 12 and the bottom case 11 of the watch 10, which are connected by adhesive. Figures 1 to 3 As shown, in this embodiment, the middle frame 12 is sleeved on the outside of the bottom case 11. The middle frame 12 is supported by the support steps 111 on the bottom case 11, and the middle frame 12 and the bottom case 11 are bonded together with adhesive. The bottom case 11 has a mounting groove, and the middle frame 12 is mounted on the bottom case 11. The side of the middle frame 12 and the mounting groove define the lug mounting cavity 13 of the watch 10, thereby supporting the middle frame 12 through the side. During disassembly, after heating and softening the adhesive between the middle frame 12 and the bottom case 11, the middle frame 12 is supported and limited, and then a pushing force is applied to the bottom case 11 to push the bottom case 11 away from the middle frame 12, thus achieving the disassembly of the bottom case 11. Of course, it is not limited to disassembling the middle frame 12 and the bottom case 11 of the watch 10 connected by adhesive; for example, it can also disassemble the middle frame 12 and the bottom case 11 connected by elastic clips. The structure of the bottom case disassembly fixture described in this embodiment is described in detail below.

[0030] like Figures 4 to 11 As shown, the bottom case disassembly fixture includes a base 20, a lifting driver (not shown), a pressure seat 30, and a push block 40. The base 20 has a through groove 21 for accommodating the middle frame 12 and the bottom case 11 and supporting the middle frame 12. The pressure seat 20 is located above the through groove 21 and is positioned at the output end of the lifting driver. The push block 40 is placed on the bottom case 11. Under the drive of the lifting driver, the pressure seat 20 pushes the push block 40 downwards, thus pushing the bottom case 12 away from the middle frame 11. By accommodating the bonded middle frame 12 and bottom case 11 through the through groove 21 and supporting the middle frame 12, and then placing the push block 40 on the bottom case 11, the lifting driver drives the pressure seat 20 to press down the push block 40, thereby achieving rapid disassembly of the bottom case 11 and the middle frame 12. This improves watch production efficiency and reduces production costs. Multiple push blocks 40 can be used, so that the push blocks 40 can be placed on the bottom shell 11 in advance, and placed together with the middle frame 12 and the bottom shell 11 in the through groove 21, which helps to improve efficiency.

[0031] The base 20 is rectangular. In this embodiment, the through groove 21 includes a through groove body 211 for accommodating the middle frame 12 and the bottom shell 11, and a support boss 212; the through groove body 211 extends from the upper surface of the base 20 to the lower surface of the base 20; the support boss 211 is disposed on both sides of the through groove body 211, for extending into the lug mounting cavity 13 of the watch 10 and abutting against the middle frame 12. By abutting against the middle frame 12 with the support boss 212, the middle frame 12 is limited and prevented from shifting downward. Preferably, the cross-sectional shape of the through groove body 211 matches the outer contour of the middle frame 12, thereby facilitating the quick positioning and placement of the middle frame 12 and the bottom shell 11. Of course, in other alternative embodiments, the cross-sectional shape of the through-slot body 211 may not match the outer contour of the middle frame 12. For example, the middle frame 12 and the bottom shell 11 can be quickly positioned by a number of limiting blocks arranged around the inner wall of the through-slot body 211. Of course, in other alternative embodiments, the base 20 is not limited to being cuboid in shape, but may also be other columnar structures, such as columnar structures with cross-sectional shapes including but not limited to circles, ellipses, polygons other than rectangles, or irregular closed curves.

[0032] In this embodiment, the push block 40 includes a push block body 41 for placement on the bottom shell 11, and a plurality of balance columns 42 for being pressed by the pressure seat 30; the balance columns 42 are arranged vertically on the push block body 41. The design of the balance columns 42 facilitates the placement and removal of the push block body 41 and ensures that pressure is evenly transmitted to the push block body 41, preventing uneven force distribution on the push block body 41 that could lead to deformation or damage to the bottom shell 11. In this embodiment, there are four balance columns 42, arranged in an array on the push block body 41. This array arrangement helps to ensure even force distribution. Of course, in other alternative embodiments, the balance columns 42 can be two, three, or more than four. In other alternative embodiments, the balance columns 42 can also be unevenly arranged; for example, some balance columns 42 can be positioned corresponding to the reinforcing ribs inside the bottom shell 11; or, they can be arranged according to the actual internal design of the bottom shell 11. In this embodiment, the balance column 42 and the push block body 41 are separate designs and can be connected by means of threads, screws, clips, or welding. Of course, in other alternative embodiments, the balance column 42 and the push block body 41 can be an integral design.

[0033] In this embodiment, the pusher body 41 includes a connecting portion 411 for extending into the middle frame 12 and an abutting portion 412 for being placed inside the bottom shell 11. The connecting portion 411 matches the inner contour of the middle frame 12, and the abutting portion 412 matches the inner contour of the bottom shell 11. The balance column 42 is connected to the abutting portion 412 through the connecting portion 411. The design of the abutting portion 412 ensures more even pressure distribution on the bottom shell 11, avoiding localized stress concentration and reducing the risk of damage to the bottom shell 11. Furthermore, the design of the connecting portion 411 and the abutting portion 412 not only enables rapid alignment of the pusher body 41, facilitating its placement on the bottom shell 11, but also prevents the pusher body 41 from tilting or shifting during pressure application. Of course, in other alternative embodiments, the abutment portion 412 may not match the internal contour of the bottom shell 11. For example, the abutment portion 412 may include several abutment blocks for abutting the bottom shell 11. The position of the abutment blocks in the connecting portion 411 can be adjusted according to the actual internal design of the bottom shell 11, and is not limited here. In addition, some abutment blocks may match the groove or hole design inside the bottom shell 11, which can also prevent the push block body 41 from tilting or shifting during the pressure process. Preferably, the abutment portion 412 is made of silicone material. Silicone material is relatively soft and can reduce the risk of damaging the bottom shell 11. Of course, in other alternative embodiments, the abutment portion 412 may also be made of materials such as rubber, plastic, thermoplastic elastomer, etc.

[0034] In this embodiment, the shape of the pressure seat 30 matches that of the base 20, and the length and width of the pressure seat 30 are greater than those of the through-slot body 211, respectively. Through the design of the pressure seat 30, the base 20 rigidly limits the downward movement of the pressure seat 30, preventing overpressure and damage to the middle frame 12. Of course, in other alternative embodiments, the length and width of the pressure seat 30 can be the same as those of the through-slot body 211, and a limiting bracket can be provided on the base 20 to rigidly limit the downward movement of the pressure seat 30.

[0035] In this embodiment, the pressure seat 30 has a plurality of guide posts 33 on the side facing the base 20, and the base 20 has a corresponding guide hole 22 on the side facing the pressure seat 30. The guide posts 33 cooperate with the guide holes 22. The cooperation between the guide posts 33 and the guide holes 22 ensures that the pressure seat 30 will not deviate when moving. Of course, in other alternative embodiments, the pressure seat 30 may have a plurality of guide holes 22 on the side facing the base 20, and the base 20 may have a corresponding guide post 33 on the side facing the pressure seat 30, with the guide posts 33 cooperating with the guide holes 22.

[0036] Furthermore, a guide sleeve 23 is provided inside the guide hole 22, and the guide hole 22 cooperates with the guide post 33 through the guide sleeve 23. The guide sleeve 23 helps to reduce the wear of the guide post 33 and improve the life of the fixture.

[0037] In some optional embodiments, an elastic element 32 is also included on the pressure seat 30, and the pressure seat 30 presses against the balance column 42 through the elastic element 32. Specifically, the pressure seat 30 has a mounting hole 31 at the position corresponding to the balance column 42, through which the balance column 42 can be inserted. The mounting hole 31 matches the balance column 42, and the elastic element 32 is disposed within the mounting hole 31. The elastic element 32 provides cushioning to prevent excessive pressure from damaging the bottom shell 11. The design of the mounting hole 31 ensures that the pressure on the balance column 42 is always vertically downward. Furthermore, a movable block (not shown) can be provided within the mounting hole 31. The movable block is disposed on the pressure seat 30 through the elastic element 32, and the pressure seat 30 presses against the balance column 42 through the movable block, thus making the pressing more stable. Preferably, the opening of the mounting hole 31 is funnel-shaped, which helps the balance column 42 to be inserted into the mounting hole 31. Of course, in some other optional embodiments, the elastic element 32 can be directly disposed on the pressure seat 30. In some alternative embodiments, the elastic element 32 is a spring. Of course, in other alternative embodiments, the elastic element 32 can be an elastic element 32 made of elastic materials such as rubber, silicone, or thermoplastic elastomer.

[0038] In this embodiment, the base 20 is provided with an opening (not shown) for removing the middle frame 12. The opening is respectively located on both sides of the through groove 21 and communicates with the through groove 21. The opening facilitates the removal of the middle frame 12 after disassembly.

[0039] In this embodiment, the lifting actuator is a drive cylinder. The downward pressure of the pressure seat 30 can be ensured by a control valve. Of course, in other alternative embodiments, the lifting actuator can be a drive motor, and the rotational motion of the drive motor can be converted into linear lifting motion using a transmission mechanism. When using a drive motor, the downward pressure of the pressure seat 30 can be ensured by adjusting the motor speed. In this embodiment, the lifting actuator is mounted above the through slot 21 via a bracket.

[0040] Compared with the prior art, the bottom shell disassembly fixture provided by this utility model can quickly disassemble the bottom shell and the middle frame by accommodating the bonded middle frame through the through groove and supporting the middle frame, and then placing the push block on the bottom shell. The push block can be pressed down by the lifting driver, thereby improving the watch production efficiency and reducing the production cost.
