[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] like Figures 1 to 6 As shown, this utility model provides a drying fixture for angled bottom shells of multi-size LED modules, including a square tray 1. The tray 1 includes a base 2, and a frame is fixedly connected to the edge of the base 2. The upper surface of the frame is higher than the upper surface of the base 2. The frame includes two parallel horizontal frames 3 and two parallel vertical frames 4, which are fixedly connected to each other to form a square frame.

[0032] A first groove 5 is provided at the connection of the horizontal frame 3 and the vertical frame 4. The first groove 5 is adapted to the four corners of the beveled bottom case of the LED module. The space enclosed by the horizontal frame 3 and the vertical frame 4 can place the beveled bottom case arranged on the LED module.

[0033] A spacer 10 is detachably connected to the frame. Specifically, a spacer 10 is detachably connected between two longitudinal frames 4. Third grooves 6 are provided on both sides of the longitudinal frame 4 connected to the spacer 10. The third grooves 6 are adapted to the bevels of the beveled bottom case of the LED module. The space enclosed by the spacer 10, the horizontal frame 3 and the longitudinal frame 4 can place two beveled bottom cases of the LED module, and the two beveled bottom cases of the LED module can be of the same or different models. In this embodiment, the spacer 10 is located at the middle position of the longitudinal frame 4. The space enclosed by the spacer 10, the horizontal frame 3 and the longitudinal frame 4 can place two beveled bottom cases of the same model of the LED module. Those skilled in the art can also appropriately adjust the relative positions of the spacer 10 and the frame according to the model of the beveled bottom case of the LED module that needs to be glued specifically to place two beveled bottom cases of different models. To meet the glue drying requirements, multiple spacers 10 can also be provided.

[0034] A plurality of support frames are also detachably connected to the chassis 2. Second grooves 7 are provided at the four corners of the support frames. The second grooves 7 are fitted with the four corners of the beveled bottom case of the LED module. The frame and the support frames form a "hui" character shape, and two support frames form a "hui" character shape.

[0035] A plurality of first positioning holes 11 and a plurality of first fixing holes 12 are provided through the chassis 2. The first positioning holes 11 are adapted to the first positioning posts fixedly connected to the back of the support frame. The first fixing holes 12 and the second fixing holes 13 provided through the support frame are in one-to-one correspondence and coaxially arranged. A plurality of first positioning holes 11 enclose a plurality of square structures, a plurality of first fixing holes 12 enclose a plurality of square structures. The cooperation of the plurality of first positioning holes 11, the plurality of first fixing holes 12 and the plurality of first positioning posts can fixedly connect support frames of different specifications to the chassis 2. The positions of the first positioning holes 11 and the positions of the first fixing holes 12 are determined according to support frames of different specifications to support beveled bottom cases of different specifications of the LED module.

[0036] In this embodiment, two support frames are connected to the chassis 2, namely a first support frame 8 and a second support frame 9. Specifically, the chassis 2 is provided with eight first positioning holes 11 and twenty first fixing holes 12. Four first positioning holes 11 and ten first fixing holes 12 form a group to fix one support frame, and the other four first positioning holes 11 and ten first fixing holes 12 form a group to fix a support frame of another specification. In this way, the eight first positioning holes 11 and twenty first fixing holes 12 cooperate with each other to support two different specifications of support frames. The two different specifications of support frames cooperate with the frame to fix and support three different specifications of LED module angled bottom shells.

[0037] When multiple support frames are fixed to the chassis 2, the upper surface of the frame is higher than the upper surface of any support frame. The cross-sections of the support frames and the frame form a trapezoidal structure. The height of the multiple support frames relative to the chassis 2 gradually decreases from the side of the frame inwards, and the cross-sections of the multiple support frames form a trapezoidal structure. In this embodiment, the frame, the first support frame 8, and the second support frame 9 are connected sequentially from the edge of the chassis 2 to the center of the chassis 2. The upper surface of the frame is higher than the upper surface of the first support frame 8, the upper surface of the first support frame 8 is higher than the upper surface of the second support frame 9, and the upper surface of the second support frame 9 is higher than the upper surface of the chassis 2.

[0038] In this embodiment, the square structure formed by the horizontal frame 3 and the vertical frame 4 can support the 320mm*320mm LED module angled bottom shell; when the spacer 10 is fixedly connected between the two vertical frames 4, the square structure formed by the spacer 10, the horizontal frame 3, and the vertical frame 4 can support two 320mm*160mm angled fixtures; after the spacer 10 is removed, the first support frame 8 and the second support frame 9 are installed on the chassis 2 to support products of 250mm*250mm and 192mm*192mm respectively. The glue drying operation can be completed for four different sizes of LED module angled bottom shells, which expands the applicability of the bottom shell glue drying fixture and greatly improves the glue drying efficiency.

[0039] Those skilled in the art can also adjust the positions of the first positioning hole 11 and the first fixing hole 12 and the specifications of the support frame according to needs and application scenarios to accommodate more different specifications of the support components.

[0040] The frame, the spacer 10, and the support frame are all provided with second positioning holes 14 that are adapted to the positioning posts on the angled bottom shell of the LED module, for fixing and supporting the angled bottom shell of the LED module.
