[0035] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0036] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0037] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] like Figures 1 to 7 As shown, according to one aspect of the utility model, a spraying fixture is provided, which is applied to a middle frame 7 of an electronic device, comprising: an upper cover 1, a bottom plate 4, a fastening pin 3 and a plurality of clamping plate assemblies 2; wherein, the structure of the upper cover 1 is the same as that of the clamping plate assemblies 2, the upper cover 1, the plurality of clamping plate assemblies 2 and the bottom plate 4 are stacked in sequence, and the middle frame 7 can be accommodated between the upper cover 1, each clamping plate assembly 2 and the bottom plate 4; the fastening pin 3 can pass through the upper cover 1, each clamping plate assembly 2 and the bottom plate 4 in sequence to lock each middle frame 7.

[0041] Specifically, in this embodiment, the spraying fixture is used to clamp and fix the middle frame 7, so as to facilitate the spraying process of the middle frame 7. The utility model arranges multiple clamping plate assemblies 2 between the upper cover 1 and the bottom plate 4, so that the middle frame 7 can be placed between the upper cover 1 and the clamping plate assembly 2 located below it, between each two adjacent clamping plates, and between the bottom plate 4 and the clamping plate assembly 2 located above it, and then the upper cover 1, each clamping plate assembly 2 and the bottom plate 4 are sequentially penetrated from top to bottom by the fastening pins 3, so as to realize the locking and fixing of the middle frame 7 clamped in each layer, so that the spraying fixture can clamp multiple middle frames 7 at a time, realize the simultaneous spraying processing of multiple middle frames 7, and improve the spraying efficiency.

[0042] In the above embodiment, the number of the splint assemblies 2 can be matched according to the actual production needs. For example, if 5 products need to be sprayed at a time, 5 splint assemblies 2 can be matched, if 6 products need to be sprayed, 6 splint assemblies 2 can be matched, and if 7 products need to be sprayed, 7 splint assemblies 2 can be matched. The spraying fixture can be matched according to the needs. In actual applications, the insertion position of the fastening pin 3 can be adaptively designed according to the position of the hole on the middle frame 7, and the length of the fastening pin 3 can also be adaptively designed according to the thickness of the sprayed product, etc. In addition, the fastening form of the fastening pin 3 can also be designed according to actual needs, such as using a screw connection form, a latch form, a rotating pin form, etc., and the utility model does not limit this.

[0043] In this embodiment, the structure of the upper cover 1 is designed to be the same as that of the clamping plate assembly 2, that is, in actual production, the uppermost clamping plate assembly 2 can be directly used as the upper cover 1, which can protect the sprayed product on the one hand, and can save the mold for making the upper cover 1 separately on the other hand. Only one set of clamping plate assembly 2 molds is needed, which simplifies the structure of the spraying fixture and saves its production cost. In addition, in order to ensure the quality of spraying and avoid the occurrence of defective products such as oily skin during the spraying process, the adaptability of the outer edge size of the bottom plate 4 and the clamping plate assembly 2, as well as the matching clearance with the product, needs to be considered during the design.

[0044] like Figures 1 to 6 As shown, optionally, the fastening pin 3 includes a pin shaft 32 and a limiting portion 31 and a locking portion 33 located at both ends of the pin shaft 32, and a matching portion 41 is provided on the base plate 4; the fastening pin 3 can be rotated to engage the locking portion 33 with the matching portion 41, and the upper cover 1, each clamping plate assembly 2 and the base plate 4 are all located between the limiting portion 31 and the locking portion 33.

[0045] Specifically, in this embodiment, after the fastening pin 3 is assembled, the pin shaft 32 passes through the upper cover 1, each clamping plate assembly 2 and the bottom plate 4, the limiting portion 31 is limited to the upper end surface of the upper cover 1, and the locking portion 33 is connected with the matching portion 41 by clamping, so that the entire spraying fixture can clamp and fix the middle frame 7 clamped in each layer, so as to facilitate the spraying process. Among them, the locking portion 33 and the matching portion 41 on the bottom plate 4 are connected in a clamping form by rotation, which makes the assembly of the fastening pin 3 simpler and improves the reliability of clamping the middle frame 7. In addition, the length of the pin shaft 32 can be designed to match the number and thickness of the clamped middle frame 7, which simplifies the production difficulty of the fixture.

[0046] Optionally, refer to Figure 3 , the projection of the pin shaft 32 covers the locking portion 33 .

[0047] Specifically, in this embodiment, the projection of the pin 32 covers the locking portion 33, so that the size of the locking portion 33 is smaller than the size of the pin 32, so that during the assembly process, the size of the entire fastening pin 3 is smaller, and it is not necessary to be limited to the shape and size of the hole on the product, thereby improving the adaptability of the spraying fixture. In practical applications, the shape of the pin 32 can be designed to be cylindrical to fit the holes on most products, improve the adaptability of the spraying fixture, and facilitate the fastener to rotate the pin 32 when locking.

[0048] Optionally, refer to Figure 3 The locking portion 33 is configured as a hook, the matching portion 41 is configured as a first through hole 42 , and the projection of the pin shaft 32 covers the first through hole 42 , and the hook can pass through the first through hole 42 and hook at the edge of the first through hole 42 .

[0049] Specifically, in this embodiment, the locking portion 33 is designed in the form of a hook, so that in the actual assembly process, the fastening pin 3 can first be sequentially inserted through the upper cover 1 and each clamping plate assembly 2 to the matching portion 41 of the bottom plate 4, and then the fastening pin 3 is rotated so that the hook can be hooked at the edge of the first through hole 42 to prevent it from being separated from the matching portion 41. This locking form of the fastening pin 3 can, on the one hand, simplify the locking method of the fastening pin 3 without the need for additional parts for auxiliary locking, and on the other hand, it is also easy to disassemble, thereby improving the disassembly and assembly efficiency of the spraying products such as the middle frame 7 and improving the efficiency of the entire production line.

[0050] Alternatively, if Figure 5 to Figure 6 As shown, a second through hole 43 is further provided on a side of the first through hole 42 away from the upper cover 1 , and an area of ​​the second through hole 43 is larger than an area of ​​the first through hole 42 , so that the locking portion 33 can be hidden in the bottom plate 4 .

[0051] Specifically, in the present embodiment, the second through hole 43 is connected to the first through hole 42 and is arranged on a side of the base plate 4 away from the upper cover 1, that is, on the lower side of the base plate 4, so that after the locking portion 33 of the fastening pin 3 passes through the first through hole 42, it is rotated and clamped at the edge of the first through hole 42, and is hidden in the second through hole 43, thereby preventing the locking portion 33 from protruding from the bottom of the base plate 4, thereby improving the aesthetics of the product, and at the same time, it can also prevent external structures or human accidental touches from causing the fastening pin 3 to be unlocked, thereby improving the clamping reliability of the spray fixture.

[0052] In one embodiment, the pin 32 is cylindrical, the hook of the locking portion 33 is a racetrack shape smaller than the cylindrical cross section, and the shape of the first through hole 42 can be a waist-shaped hole (racetrack shape) with the same shape as the locking portion 33, and the second through hole 43 can be designed to be a circle larger than the first through hole 42 to simplify the entire locking process and the structure of the clamp. In practical applications, the locking portion 33 can also be designed to be a non-circular polygonal shape, etc., and the utility model does not limit this.

[0053] Alternatively, if Figures 1 to 4 As shown, a plurality of fastening pins 3 are provided, and the plurality of fastening pins 3 are evenly arranged at the edge of the clamping plate assembly 2 .

[0054] Specifically, in this embodiment, a plurality of fastening pins 3 are provided and evenly arranged at the edge of the clamping plate assembly 2, so that the force at each clamping plate assembly 2 is relatively uniform, the flatness of the clamping plate assembly 2, the upper cover 1 and the bottom plate 4 is improved, and the spraying quality is improved. In practical applications, the specific number and position of the fastening pins 3 can be adaptively designed according to the position and number of holes on the specific product, and it can be as uniform as possible, and the utility model does not limit this.

[0055] In addition, in order to improve the flatness of the clamping plate assembly 2, the upper cover 1 and the bottom plate 4 and prevent them from deforming during high-temperature baking, the materials of each component can be made of high-temperature resistant materials such as ABS+20% glass fiber (20% glass fiber is added to ABS plastic). Furthermore, the strength of the fastening pin 3 has a great influence on the reliability of the entire spraying fixture. In actual production, the diameter of the fastening pin 3 can be made as large as possible according to actual needs to improve its strength, thereby improving the clamping force of each clamping plate assembly 2 for the sprayed product and improving the reliability of the fixture.

[0056] Alternatively, if Figure 7 As shown, the clamping plate assembly 2 includes an upper plate 21 and a lower plate 22 , the upper plate 21 and the lower plate 22 are detachably connected, and the upper surface of the upper plate 21 and the lower surface of the lower plate 22 can accommodate the middle frame 7 .

[0057] Specifically, in this embodiment, the upper plate 21 and the lower plate 22 are detachable so that in actual production, a set of molds can be used to make the upper plate 21 and the lower plate 22, and then the upper plate 21 and the lower plate 22 are assembled, thereby improving assembly efficiency and production costs. When it is used in a spraying fixture, the middle frame 7 and other products can be clamped on the upper surface of the upper plate 21 of one clamping plate assembly 2 and the small surface of the lower plate 22 of another adjacent clamping plate assembly 2.

[0058] Alternatively, if Figure 7 As shown, a first positioning hole 24 and a first positioning column 25 are respectively provided on the upper plate 21 and the lower plate 22 , and the first positioning column 25 passes through the first positioning hole 24 .

[0059] Specifically, a first positioning hole 24 is provided on the upper plate 21, and a first positioning column 25 is provided on the lower plate 22, so that when the upper plate 21 and the lower plate 22 are assembled, the upper plate 21 and the lower plate 22 can be precisely positioned by simply inserting the first positioning column 25 into the second positioning hole, thereby improving assembly efficiency. In practical applications, the first positioning column 25 can also be designed on the upper plate 21, and the first positioning hole 24 can be provided on the lower plate 22, and the utility model does not limit this.

[0060] Alternatively, if Figure 7 As shown, the upper plate 21 and the lower plate 22 are connected by a buckle 23.

[0061] Specifically, in this embodiment, before assembling the clamp assembly 2 on the spraying fixture, the upper plate 21 and the lower plate 22 can be first connected together by snapping together the buckles 23, which further improves the assembly efficiency of the upper plate 21 and the lower plate 22. In addition, the buckle 23 connection can also prevent the upper plate 21 and the lower plate 22 from being misaligned in the horizontal direction, thereby improving the product precision.

[0062] Alternatively, if Figures 1 to 3As shown, the upper surface of the bottom plate 4 and the upper surface of the clamping plate assembly 2 are both provided with second positioning columns 5 , and the second positioning columns 5 can position the middle frame 7 .

[0063] Specifically, in this embodiment, the upper surface of the bottom plate 4 and the upper surface of the clamping plate assembly 2 are used to place and position the middle frame 7. The second positioning column 5 can facilitate the accurate positioning of the middle frame 7, improve the assembly efficiency and spraying quality. The setting position can be adaptively designed according to the position of the hole on the actual product. In addition, the height of the second positioning column 5 can also be designed to match the limiting function of the fastening pin 3 in the height direction.

[0064] Alternatively, if Figure 1 As shown, a first boss 51 and a second boss 52 are stacked on the second positioning column 5 . The first boss 51 is used to position the middle frame 7 , and the second boss 52 is used to position the clamping plate assembly 2 .

[0065] Specifically, in this embodiment, the second positioning column 5 positions the middle frame 7 through the first boss 51, and positions the clamping plate assembly 2 through the second boss 52, thereby achieving the positioning accuracy of the entire spraying fixture for the middle frame 7 and the assembly accuracy of each clamping plate assembly 2, thereby improving the spraying quality of the product.

[0066] Alternatively, if Figures 1 to 3 As shown, a plurality of second positioning columns 5 are disposed on the upper surface of the base plate 4 and the upper surface of the clamping plate assembly 2 .

[0067] Specifically, in practical applications, the number and positions of the second positioning columns 5 can be adaptively designed according to the actual product, and the assembly accuracy of the product and the splint assembly 2 can be further improved by providing a plurality of second positioning columns 5 .

[0068] Alternatively, if Figures 1 to 3 as well as Figure 5 As shown, it also includes a rotating column 6, which is connected to a side of the bottom plate 4 away from the upper cover 1 and is used to assemble the spraying fixture on an external device.

[0069] Specifically, in practical applications, the spraying fixture usually needs to be assembled on the spraying line. The design of the rotating column 6 allows the entire spraying fixture to be assembled on the spraying line, so that the spraying fixture can rotate and move with the spraying line. Multiple spraying fixtures can usually be assembled on the spraying line to improve production efficiency.

[0070] According to the second aspect of the present invention, referring to Figures 1 to 7 As shown, a spraying production line is provided, including the spraying fixture of the first aspect.

[0071] Specifically, in this embodiment, the spraying fixture provided by the first aspect of the present application is used in the spraying production line to fix the middle frame 7 so as to perform spraying processing on it. The spraying fixture provided by the first aspect of the utility model has the advantages of simple structure and a large number of clamped middle frames 7, thereby improving the spraying efficiency and production cost of the spraying production line.
