[0029] It should be noted that in the embodiment, the number of arc-shaped racks is selected according to the size of the actual product, the fan-shaped bottom plate 1 is provided with at least one partition plate 2 in the axial direction, and the number of layers of the partition plate 2 can be stacked according to the actual situation; the partition plate 2 after stacking and the partition plate 2 are connected through the spacing column 5;
[0030] It can be understood that a universal fan-shaped carrier frame is used for placing during PCBA coating, by placing the PCBA in the carrier frame composed of the fan-shaped bottom plate 1 and the partition plate 2, selecting the corresponding arc-shaped rack according to the size of the PCBA, adjusting the spacing between the arc-shaped racks according to the actual placement situation, and using the tooth grooves on the arc-shaped racks to realize the ordered placement of the PCBA, when facing PCBA of different sizes, only the arc-shaped rack with the corresponding tooth groove width needs to be replaced, without the need to replace the entire carrier frame, solving the problems of special design of carrier frame for different products, long development cycle, low utilization rate, and high customization cost, through simple splicing, the loading needs of products of different sizes are met, the utilization rate of the carrier frame is improved, and the coating cost is reduced; only the corresponding rack of the new product needs to be customized during use, the development cycle of the carrier frame is shortened, the customization cycle of the carrier frame is also shortened, and the product production time of the customer is saved.
[0031] Specifically, please refer to Figure 2 , Figure 3 On the basis of the above embodiment, the arc-shaped rack comprises a single-sided tooth rack plate 3 and a double-sided tooth rack plate 4, the number of the single-sided tooth rack plate 3 is two in a group, and the two single-sided tooth rack plates 3 are arranged on the smallest arc-shaped section and the largest arc-shaped section of the partition plate 2 respectively, and the double-sided tooth rack plate is arranged between the two single-sided tooth rack plates 3 and connected with the partition plate 2; at the same time, the teeth on the single-sided tooth rack plate 3 are arranged towards the direction of the double-sided tooth rack plate 4. It can be understood that the combination of single-sided teeth and double-sided teeth can reduce unnecessary processing, thereby saving processing cost, and also avoiding the situation that the exposed teeth cause cuts to workers.
[0032] Specifically, please refer to Figure 2 , Figure 3On the basis of the above embodiment, the partition plate 2 is provided with a plurality of first mounting holes, and the first mounting holes arranged on the same radial direction are consistent in number and hole center distance. The first mounting holes are used to match the arc-shaped rack. The left and right ends of the double-sided tooth rack plate 4 are provided with mounting plates, and the mounting plates are provided with second mounting holes. The second bolt 7 and the nut 8 are further included. The second bolt 7 passes through the arc-shaped rack and the partition plate 2 and is connected with the second bolt 7 through the nut 8.
[0033] It can be understood that the first mounting hole and the second mounting hole are screw holes. The connection between the double-sided tooth rack plate 4 and the partition plate 2 is realized by passing the second bolt 7 through the first mounting hole and the second mounting hole. Then, the nut 8 is used for locking. At the same time, the single-sided tooth rack plate 3 is also connected with the partition plate 2 through screw holes. This connection mode can realize the disassembly and installation of the arc-shaped rack, and the operation mode is simple, which improves the application range of the carrier frame.
[0034] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 On the basis of the above embodiment, the screw 6 and the first bolt are further included. The screw 6 passes through the bottom of the spacing column 5 and is connected with the fan-shaped bottom plate 1. The first bolt passes through the partition plate 2 and is connected with the spacing column 5. It can be understood that the screw 6 connection mode is relatively simple and does not require special assembly equipment. Only ordinary tools such as screwdrivers are needed to complete the assembly. At the same time, the bolt connection is relatively fast during assembly. Usually, only the bolt needs to pass through the corresponding mounting holes of the partition plate 2 and the spacing column 5, and then it can be tightened.
[0035] Specifically, please refer to Figure 2 On the basis of the above embodiment, a plurality of through grooves are formed in the fan-shaped bottom plate 1. It can be understood that the through grooves are formed without affecting the use, which can effectively reduce the weight of the carrier frame and save the materials for manufacturing the carrier frame.
[0036] Specifically, please refer to Figure 3 On the basis of the above embodiment, the tooth widths and tooth pitches of the double-sided tooth rack plate 4 on both sides are different. It can be understood that the tooth widths and tooth pitches of the double-sided tooth rack plate 4 on both sides can be the same or different. By setting different tooth widths and tooth pitches, different sizes of PCBA can be placed in one carrier frame.
[0037] Specifically, on the basis of the above-mentioned embodiments, the arc-shaped rack is provided with a symbol mark for preventing wrong installation; it can be understood that the symbol mark can be a numerical mark, an alphabetical mark, a graphical mark, and a combination of the aforementioned marks. By setting the symbol mark, the arc-shaped rack can be prevented from being operated incorrectly during installation, and the installation speed can be improved. Meanwhile, a unique number can be engraved, which is equivalent to the identity card of the arc-shaped rack. When the arc-shaped rack is replaced, as long as the arc-shaped rack corresponding to the number of the product is found and locked by a screw, the arc-shaped rack can be avoided from being incorrectly matched.
[0038] It should be noted that in this document, the terms "comprise", "comprising", or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, device, article, or method that comprises a list of elements does not only include those elements, but can also include other elements not expressly listed or inherent to such process, device, article, or method.
