[0023] See also Figure 1-5 The mobile phone shell material structural component stacking and spraying fixture implemented in the embodiment includes a bottom plate 1, a middle plate 2 and a panel 4. The middle plate 2 is provided with a plurality of blocks. When stacking and assembling, the number of blocks of the middle plate 2 can be preset according to the needs of the enterprise. For example, the number of blocks of the middle plate 2 is three. The stacking and assembling from bottom to top are specifically the bottom plate 1, the product 15, the middle plate 2, the product 15, the middle plate 2, the product 15, the middle plate 2, the product 15 and the panel 4. If the number of the middle plate 2 is other, the stacking and assembling arrangement is similar;

[0024] The middle plate 2 is in a shell shape, and the middle plate 2 is embedded in the interior of the product 15. The shell surface of the shell-shaped middle plate 2 is used to support the inner wall of the product 15. During spraying, the shell surface of the shell-shaped middle plate 2 maintains the shape of the inner wall of the product 15.

[0025] The top of the middle plate 2 is an open end 2a, and the inner bottom surface of the middle plate 2 is provided with a positioning block. The top of the first positioning block passes through the open end 2a of the middle plate 2. The bottom surface of the panel 4 is provided with a first protruding block 5, and the top surface of the bottom plate 1 is provided with a second protruding block 6. The height of the positioning column is higher than the height of the mobile phone shell material structure. The positioning block, the first protruding block 5 and the second protruding block 6 are provided to raise the product 15, so that there are gaps between the product 15 and the bottom plate 1, between the middle plates 2 and between the panels 4, to ensure that the paint can be sprayed to the inner side of the product 15, improve the utilization rate of the spray paint, and greatly reduce the production cost;

[0026] The bottom plate 1, the middle plate 2 and the panel 4 are all provided with a matching opening 14 for matching with the opening of the mobile phone case material structure. A locking rod 12 is provided in the matching opening 14. The matching opening 14 cooperates with the locking rod 12 to lock the bottom plate 1, the middle plate 2, the panel 4 and the product 15, thereby improving the stability during spraying, ensuring the normal spraying work, and further improving the spraying efficiency.

[0027] In this embodiment, a positioning platform 7 is provided on the bottom surface of the bottom plate 1, and a positioning hole 8 is provided on the positioning platform 7. The positioning hole 8 cooperates with the positioning rod of the spray line to facilitate the clamp to clamp the product 15 for spraying.

[0028] In this embodiment, the bottom surface of the middle plate 2 and the bottom surface of the panel 4 are both provided with pads 9, which are used to reduce the contact area between the middle plate 2 and the product 15, as well as the contact area between the panel 4 and the product 15, to prevent the product 15 from sticking to the middle plate 2 or the panel 4, thereby reducing the disassembly and assembly time.

[0029] In this embodiment, the top surface of the panel 4 and the bottom surface of the bottom plate 1 are both provided with reinforcing ribs 10, and the reinforcing ribs 10 are used to strengthen the structure of the panel 4 and the structure of the bottom plate 1, thereby increasing the service life of the panel 4 and the bottom plate 1.

[0030] In this embodiment, an indicator symbol 11 is provided on the top surface of the panel 4 , and the indicator symbol 11 points to the mating opening 14 , which is convenient for reminding the staff and saving assembly time.

[0031] In this embodiment, the locking rod 12 includes a gripping portion 12a, a rod body 12b and a locking portion 12c, and the rod body 12b is disposed between the gripping portion 12a and the locking portion 12c.

[0032] Specifically, the mating opening 14 includes a through-opening body 14a, a first bayonet body 14b and a second bayonet body 14c. The first bayonet body 14b is arranged on the panel 4. The diameter of the clamping portion 12a is larger than the diameter of the first bayonet body 14b. The through-opening body 14a is arranged on the middle plate 2. The rod 12b passes through the through-opening body 14a. The second bayonet body 14c is arranged on the bottom plate 1. The locking portion 12c is arrow-shaped. The length of the second bayonet body 14c is not less than the tail length of the arrow-shaped locking portion 12c. The width of the second bayonet body 14c is not greater than the tail length of the arrow-shaped locking portion 12c.

[0033] The tightening process of the embodiment of the utility model is as follows: the staff pinches the pinching part 12a, so that the rod body 12b passes through the panel 4, the first bayonet body 14b, the product 15, the opening, the middle plate 2, the through-mouth body 14a, the product 15 opening and the bottom plate 1 in sequence, and the tail of the arrow-shaped locking part 12c passes through the second bayonet body 14c, and the pinching part 12a is rotated, and then the tail of the arrow-shaped locking part 12c is stuck in the position where the width of the second bayonet body 14c is not greater than the length of the tail of the arrow-shaped locking part 12c.

[0034] In this embodiment, the top of the first positioning block exceeds the open end 2a of the middle plate 2 by 0.5 mm, and the first protruding block 5 and the second protruding block 6 are both 0.5 mm. 0.5 mm is the optimal value to ensure that the paint can be sprayed on the inner side of the product 15. When stacking, there is a 0.5 mm spacing between the product 15 and the middle plate 2, between the product 15 and the panel 4, and between the product 15 and the bottom plate 1, which not only improves the utilization rate of the spray paint, but also greatly reduces the production cost.

[0035] The above contents are further detailed descriptions of the present invention in combination with specific further embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
