[0069] The MacBook small part fixing mechanism of the embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

[0070] Refer to Figures 1 to 8 As shown, the MacBook small part fixing mechanism provided by the embodiment of the present utility model includes a connection block 10, a loading platform 20, a first fixing member 30 and a second fixing member 40.

[0071] The connection block 10 is adapted to be fixed on a jig, and an installation hole 101 is provided in the middle of the connection block 10.

[0072] The stage 20 is disposed within the mounting hole 101 and can float in the height direction of the connecting block 10. A receiving groove 201 is provided in the middle of the stage 20 for receiving small parts of the MacBook. It should be noted that in order to reduce the weight of the pressure-holding fixture and facilitate operation, the fixture is basically made of aluminum material, thus greatly reducing the weight of the fixture. However, since the stage 20 floats up and down each time it is used, and the hardness of the aluminum material is limited, the stage 20 will be worn after multiple uses, resulting in unstable floating. Therefore, to solve this problem, the connecting block 10 (this connecting block 10 is made of high-hardness metal material) is specifically designed, inlaid on the fixture, and the stage 20 (this stage 20 is also made of high-hardness metal material) is disposed within the connecting block 10, so as to ensure the long service life of the stage 20 while ensuring the light weight of the fixture.

[0073] The first fixing member 30 is slidably disposed on the stage 20, and one end extends into the receiving groove 201 for abutting against the side surface of the small part of the MacBook.

[0074] The second fixing member 40 is slidably disposed on the stage 20 and is perpendicular to the first fixing member 30. One end of the second fixing member 40 extends into the receiving groove 201 for abutting against the other side surface of the small part of the MacBook.

[0075] Based on the above, it is fixed on the fixture through the connecting block 10, and the stage 20 is allowed to float in the height direction within the connecting block 10. This design enables each small part of the MacBook to be in close contact with the product through its floating effect when installing multiple small parts of the MacBook at the same time, so as to ensure the stability of installing multiple small parts of the MacBook at the same time. The first fixing member 30 and the second fixing member 40 are both slidably disposed on the stage 20. This design also facilitates the user to accurately position and fix according to the specific shape and size of the small part of the MacBook. By stably and reliably fixing the small part of the MacBook, it helps to improve the processing efficiency, and at the same time reduce the damage or error caused by unstable fixing, thereby improving the product quality.

[0076] Preferably, in an embodiment of the present invention, a first sliding groove 202 is horizontally provided on the stage 20, and the first fixing member 30 is slidably disposed within the first sliding groove 202.

[0077] A second sliding groove 203 is longitudinally provided on the stage 20, and the second fixing member 40 is slidably disposed within the second sliding groove 203.

[0078] Thus, this design enables the first fixing member 30 and the second fixing member 40 to slide freely on the stage 20, thereby enabling flexible adjustment of their positions. This is particularly important for application scenarios that require precise positioning or adaptation to objects of different sizes and shapes, greatly improving the adaptability and flexibility of the device.

[0079] Preferably, in an embodiment of the present invention, the first fixing member 30 includes a first sliding column 301 and a first pressing block 302.

[0080] The first sliding column 301 is slidably disposed in the first sliding groove 202.

[0081] The first pressing block 302 is disposed at the end of the first sliding column 301, and one end of the first pressing block 302 extends into the accommodating groove 201 to press against the side surface of the small MacBook.

[0082] Thus, the slidable design of the first sliding column 301 in the first sliding groove 202 enables the first pressing block 302 to be precisely adjusted to the desired position. One end of the first pressing block 302 extends into the accommodating groove 201, which can directly press against the side surface of the small MacBook (or other electronic device parts of similar size), achieving a stable fixing effect. The design of the first pressing block 302 usually takes into account the protection of the small MacBook, and a soft material or a design with a buffer pad is adopted to reduce the pressure on the side surface of the workpiece and avoid scratches or damage.

[0083] Preferably, in an embodiment of the present invention, a first stopper 303 is provided on the side surface of the stage 20. The first stopper 303 is disposed opposite to the first sliding groove 202. A first spring member 304 is provided at the tail end of the first sliding column 301, and the other end of the first spring member 304 is connected to the first stopper 303.

[0084] Thus, the elastic force provided by the first spring member 304 ensures that the first pressing block 302 can continuously and evenly apply pressure to the small MacBook, thereby achieving a tighter and more stable fixation. At the same time, since the elastic force of the spring is controllable, it can be ensured that the small MacBook will not be subjected to excessive pressure or damage during fixation.

[0085] Preferably, in an embodiment of the present invention, the second fixing member 40 includes a second sliding column 401 and a second pressing block 402.

[0086] The second sliding column 401 is slidably disposed in the second sliding groove 203.

[0087] The second pressing block 402 is arranged at the end of the second sliding column 401, and one end of the second pressing block 402 extends into the accommodating groove 201 for pressing against the other side surface of the small MacBook parts.

[0088] In this way, through the combined use of the first fixing member 30 and the second fixing member 40, both side surfaces of the small MacBook parts are effectively pressed and fixed. This all-round fixing method greatly enhances the stability of the device. Since the second sliding column 401 and the second pressing block 402 are also slidable and cooperate with the second sliding groove 203, they can easily adapt to small MacBook parts of different sizes. This flexibility enables the fixing system to be widely applied in various scenarios and requirements.

[0089] Preferably, in an embodiment of the present invention, a second stop block 403 is arranged on the other side surface of the loading platform 20. The second stop block 403 is arranged opposite to the second sliding groove 203. A second spring member 404 is arranged at the tail end of the second sliding column 401, and the other end of the second spring member 404 is connected to the second stop block 403.

[0090] In this way, the second spring member 404 automatically adjusts the positions of the second sliding column 401 and the second pressing block 402 through its elastic force to ensure that they can tightly press against the other side surface of the small MacBook parts. This automatic adjustment mechanism not only improves the stability of the fixation but also reduces the risk of insecure fixation caused by improper manual operation.

[0091] Advantageously, by replacing the second spring member 404 with different strengths or lengths, it is possible to adapt to the requirements of small MacBook parts of different sizes, weights or shapes for the fixing pressure. This flexibility makes the fixing system more versatile and practical.

[0092] Preferably, in an embodiment of the present invention, a first limiting portion 204 is further included. The first limiting portion 204 is arranged on the loading platform 20 and is located on the side away from the first fixing member 30. The side surface of the first limiting portion 204 is flush with the groove wall on the side of the accommodating groove 201 away from the first fixing member 30 to cooperate with the first fixing member 30 to limit the small MacBook parts.

[0093] In this way, the first limiting portion 204 and the first fixing member 30 are respectively located on both sides of the MacBook small part and are flush with the corresponding groove walls of the accommodating groove 201, jointly forming a stable limiting framework. The first limiting portion 204 not only provides physical obstruction but also enhances the fixing effect of the first fixing member 30 through its structural design. When the first pressing block 302 presses against the MacBook small part, the first limiting portion 204 serves as a support point, making the fixing force more uniform and stable, thereby improving the reliability and durability of the fixing.

[0094] Preferably, in an embodiment of the present invention, a second limiting portion 205 is further included. The second limiting portion 205 is provided on the carrier 20 and is located on the side away from the second fixing member 40. The side surface of the second limiting portion 205 is flush with the groove wall of the accommodating groove 201 on the side away from the second fixing member 40 to cooperate with the second fixing member 40 to limit the MacBook small part.

[0095] In this way, the second limiting portion 205 is flush with the groove wall of the accommodating groove 201, forming a stable side support, and jointly acting with the second fixing member 40 to perform two-way limiting on the MacBook small part. This design effectively prevents the MacBook small part from shifting or toppling when subjected to lateral force, improving the stability of the fixing.

[0096] At the same time, although the design of the second limiting portion 205 is mainly based on the general size of the MacBook small part, its flush design with the groove wall of the accommodating groove 201 enables the fixing system to have a certain adaptability to slightly larger or smaller workpieces. By adjusting the position and force of the second fixing member 40, it can cooperate with the second limiting portion 205 to effectively limit MacBook small parts of different sizes.

[0097] Preferably, in an embodiment of the present invention, a plurality of convex portions 206 are provided on the bottom surface of the carrier 20. The plurality of convex portions 206 are arranged in a rectangular array, and a third spring member 207 is provided on the bottom surface of each convex portion 206.

[0098] Thus, during the installation of MacBook small parts, when the workpiece abuts against the MacBook small parts and is pressed down, this design enables the entire carrier 20 to sink, and the third spring member 207 plays a crucial role in this process. Specifically, the reaction force provided by the third spring member 207 ensures that the MacBook small parts can be stably installed on the MacBook backplane. Usually, multiple MacBook small parts are installed simultaneously. Then, since the carrier 20 is floating and supported by the third spring member 207, when the workpiece is pressed down, the carrier 20 can be finely adjusted according to the heights and positions of different MacBook small parts. This fine adjustment ensures that all MacBook small parts can be evenly attached to the MacBook backplane, avoiding the problem of insecure installation caused by height differences or position offsets.

[0099] Preferably, in an embodiment of the present invention, a first strip-shaped groove 2021 is provided at the bottom of the first chute 202, and the first strip-shaped groove 2021 penetrates to the bottom surface of the carrier 20. A first insertion hole 305 is provided at the bottom surface of the first fixing member 30, and the first insertion hole 305 and the first strip-shaped groove 2021 are vertically opposite.

[0100] A second strip-shaped groove 2031 is provided at the bottom of the second chute 203, and the second strip-shaped groove 2031 penetrates to the bottom surface of the carrier 20. A second insertion hole 405 is provided at the bottom surface of the second fixing member 40, and the second insertion hole 405 and the second strip-shaped groove 2031 are vertically opposite.

[0101] Thus, by providing the first strip-shaped groove 2021 and the second strip-shaped groove 2031 at the bottoms of the first chute 202 and the second chute 203 and penetrating these strip-shaped grooves to the bottom surface of the carrier 20, a direct access path is provided for the driving end of the disassembly table. When it is necessary to disassemble the MacBook small parts, simply insert the driving end of the disassembly table into the first insertion hole 305 and the second insertion hole 405, and then the driving end can drive the first fixing member 30 and the second fixing member 40 away from the MacBook small parts to achieve rapid disassembly. Since the first insertion hole 305 and the second insertion hole 405 are respectively vertically opposite to the first strip-shaped groove 2021 and the second strip-shaped groove 2031, this design ensures that the driving end of the disassembly table can be accurately inserted into the insertion holes and move along the lengths of the first strip-shaped groove 2021 and the second strip-shaped groove 2031.

[0102] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0103] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
