[0033] EMBODIMENT

[0034] Referring to Figures 1-2As shown, an oven structure for improving the surface consistency of lamp beads aims to improve the heating uniformity by optimizing the internal structure. The oven structure includes an outer box body 1, a partition layer 11 is arranged in the outer box body 1, and the partition layer 11 divides the inner cavity of the outer box body 1 into an upper chamber 12 and a lower chamber 13. An inner box body 2 is arranged in the lower chamber 13, which is specially used for placing LED products to be processed. The two side walls of the inner box body 2 are provided with through holes, which make the inside of the inner box body 2 communicate with the lower chamber 13, and facilitate the circulation of hot air.

[0035] A heating assembly 3 and a turbine assembly 4 are arranged in the lower chamber 13 above the inner box body 2, the turbine assembly 4 is located directly above the heating assembly 3, an air inlet opposite to the turbine assembly 4 is arranged on the partition layer 11, and a blower 5 is arranged in the upper chamber 12. The inlet of the blower 5 communicates with the outside of the outer box body 1, and the outlet of the blower 5 communicates with the air inlet through a first pipeline 6.

[0036] In this embodiment, the inner box body 2 is arranged in the middle of the lower chamber 13, the air inlet is arranged at the middle position of the partition, and the heating assembly 3 and the turbine assembly 4 are located directly below the air inlet. Through the above design, the air blown from the blower 5 forms a circulating air to the two sides through the turbine assembly 4, and the circulating air can make the hot air flow uniformly and efficiently around the inner box body 2, thereby improving the uniformity of the heating, improving the surface consistency of the lamp beads, and improving the product quality.

[0037] An exhaust fan 7 is arranged in the upper chamber 12, the outlet of the exhaust fan 7 communicates with the outside of the outer box body 1, and the inlet of the exhaust fan 7 communicates with the inner box body 2 through a second pipeline 8. The exhaust fan 7 exhausts the air in the inner box body 2 and discharges it to the outside, forming a complete air circulation path.

[0038] In this embodiment, in order to enhance the practicability and maintenance convenience of the equipment, a separate material box door is arranged on the inner box body 2, and an upper maintenance door and a lower maintenance door are arranged on the outer box body 1 surrounding the inner box body 2. The upper maintenance door is used to open the upper chamber 12, and the lower maintenance door is used to open the lower chamber 13 except the inner box body 2. Through these designs, the convenience of maintenance and maintenance operation is improved.

[0039] In this embodiment, in order to improve the overall operability and manageability of the oven, a control cabinet 100 is specially arranged on the outside of the outer box body 1. The control cabinet 100 integrates a variety of key components inside, including a control unit responsible for the running logic of the oven, a power supply unit providing stable power, a control panel convenient for user operation, and a control switch for starting or stopping the oven.

[0040] By integrating these components within a control cabinet 100, we ensure that each part of the oven works accurately and in coordination according to the preset program and parameters. At the same time, the arrangement of the control panel and control switch allows the user to intuitively monitor the operation of the oven and make necessary adjustments as needed.

[0041] In this embodiment, the through holes on both sides of the inner box body 2 are of the same structure and are symmetrically distributed. Specifically, the through holes on each side are arranged in a circumferential array or a rectangular array on the inner box body 2, so that the external hot air can enter the inner box body 2 evenly, thereby improving the heating performance of the oven.

[0042] In this embodiment, in order to further optimize the flow path of hot air and improve the heating efficiency, a horn-shaped guide plate 10 is arranged at the air inlet, and the guide plate 10 is located in the lower chamber 13 and faces the turbine assembly 4. Through such a design, the hot air entering from the air inlet can be effectively guided and accelerated, improving the air flow rate in the lower chamber 13, and increasing the amount of hot air entering the inner box body 2 under the driving of the circulating air.

[0043] In combination with Figure 3 As shown in the figure, the heating assembly 3 includes a heating frame 31, and a resistance wire assembly 32 is installed in the heating frame 31 for generating heat. In order to ensure the safety and efficiency of the heating process, heat insulation foot pads 33 are specially arranged at the four corners of the heating frame 31. These heat insulation foot pads 33 not only effectively isolate the heat generated by the heating frame 31 to prevent adverse effects on the inner box body 2, but also slightly lift the heating frame 31 as a whole, facilitating the circulation of hot air in the inner box body 2.

[0044] In order to ensure the cleanliness of the air entering the oven, an air filtration assembly 9 is additionally arranged on the pipeline through which the air blower 5 communicates with the outside of the outer box body 1. The air filtration assembly 9 mainly consists of a filter box and a primary filter, and the primary filter is installed in the filter box.

[0045] The primary filter can effectively block dust, hair and other large-particle impurities in the external air, ensuring that only purified air can enter the interior of the oven. Such a design not only improves the cleanliness of the interior of the oven, but also prolongs the service life of the internal components of the oven.

[0046] The application of the outer box body 1 and the inner box body 2 realizes the oven structure with air inlet in the middle and air outlet on both sides, and the size of the air outlet on both sides can be adjusted through the turbine assembly 4, thereby ensuring the uniformity of the temperature and air speed inside the inner box body 2, improving the uniformity of the heating of the LED products in the oven, and improving the consistency of the color of the lamp beads in each batch.
