Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 4As shown, an embodiment of the present invention provides a material box structure, including: a material box body 10, the side wall of the material box body 10 having a plurality of spaced mounting holes 11; a cover plate assembly 20, the cover plate assembly 20 including a fixing member 21, a rolling member 22 and a plurality of placement members 23 spaced on the fixing member 21, the plurality of placement members 23 being inserted into the corresponding plurality of mounting holes 11 and being limited to the inner wall of the material box body 10, the fixing member 21 being detachably connected to the side wall of the material box body 10, the rolling member 22 being disposed on the placement member 23, the rolling member 22 being used to roll and cooperate with a carrier plate or lead frame inserted into the cavity of the material box body 10.

[0026] In this design, multiple placement components 23 are inserted into corresponding mounting holes 11, and the placement components 23 are mutually restrained by the inner wall of the material box body 10. This allows the placement components 23 to be fixed within the cavity of the material box body 10. Simultaneously, a rolling element 22 is mounted on the placement component 23, enabling it to roll with the carrier plate or lead frame inserted into the cavity of the material box body 10. This reduces friction between the carrier plate or lead frame and the placement component 23, effectively preventing deformation or loss of individual products on the carrier plate or lead frame. Furthermore, the fixing element 21 is detachably connected to the side wall of the material box body 10, facilitating both fixing and disassembly of the placement component 23.

[0027] There are multiple rolling elements 22, which are spaced apart on the placement element 23.

[0028] This design can further reduce the friction between the carrier plate or lead frame and the placement component 23, and more effectively prevent the deformation or loss of individual products on the carrier plate or lead frame.

[0029] In this embodiment, the rolling element 22 includes a first rolling wheel 221 and a second rolling wheel 222. The first rolling wheel 221 and the second rolling wheel 222 are arranged side by side on the placement element 23. Both the first rolling wheel 221 and the second rolling wheel 222 are used to roll and cooperate with the carrier plate or lead frame inserted into the cavity of the material box body 10.

[0030] With the above arrangement, the first roller 221 and the second roller 222 are arranged side by side on the placement member 23, which facilitates rolling cooperation with the carrier plate or lead frame inserted into the cavity of the material box body 10, so that the carrier plate or lead frame can be smoothly inserted.

[0031] The placement component 23 has a rolling hole. The first rolling wheel 221 includes a pulley 2211 and a rotating shaft. The two ends of the rotating shaft are connected to the two opposite inner walls of the rolling hole. The pulley 2211 is sleeved on the rotating shaft and has a clearance fit with the rotating shaft.

[0032] With this configuration, the pulley 2211 is fitted onto the rotating shaft and has a clearance fit with the rotating shaft, so that the pulley 2211 can rotate around the rotating shaft, thereby achieving the purpose of rolling fit with the carrier plate or lead frame inserted into the cavity of the material box body 10.

[0033] In this embodiment, the placement member 23 includes a first placement plate 231 and a second placement plate 232. The first placement plate 231 and the second placement plate 232 are spaced apart on the fixing member 21, and the rolling member 22 is disposed on the first placement plate 231 and / or the second placement plate 232.

[0034] In this solution, the rolling element 22 can be disposed on the first placement plate 231 and / or the second placement plate 232.

[0035] Furthermore, the first placement plate 231 includes a plate body 2311 and a plurality of perforated cover plates 2312. The plate body 2311 has a plurality of through holes, and the perforated cover plates 2312 are disposed on the plate body 2311. The perforated cover plates 2312 have a plurality of small holes, which are connected to the through holes. The plurality of perforated cover plates 2312 and the plurality of through holes are arranged in a one-to-one correspondence.

[0036] This design connects the pinholes and through-holes, preventing contact scratches when cleaning individual products on the carrier board or lead frame, thus ensuring the safety of each product.

[0037] Specifically, the fixing component 21 includes a vertical plate 211 and multiple horizontal plates 212. The multiple horizontal plates 212 are spaced apart on the vertical plate 211, and the placement component 23 is placed on the horizontal plate 212. The multiple horizontal plates 212 and the multiple placement components 23 are arranged in a one-to-one correspondence. Both the vertical plate 211 and the horizontal plate 212 are connected to the material box body 10.

[0038] The above setup allows for the one-to-one connection of multiple horizontal plates 212 and multiple placement components 23.

[0039] The material box structure includes a first fastener and a second fastener. The vertical plate 211 has a first connecting hole 2111, the horizontal plate 212 has a second connecting hole 2121, and the side wall of the material box body 10 has a first assembly hole 12 and a second assembly hole 13. The first fastener passes through the first connecting hole 2111 and the first assembly hole 12 in sequence to connect the vertical plate 211 and the material box body 10. The second fastener passes through the second connecting hole 2121 and the second assembly hole 13 in sequence to connect the horizontal plate 212 and the material box body 10.

[0040] The first fastener connects the vertical plate 211 to the material box body 10; the second fastener connects the horizontal plate 212 to the material box body 10.

[0041] In this embodiment, the material box body 10 has a receiving cavity 14 communicating with the mounting hole 11. The inner wall of the receiving cavity 14 has a plurality of slots 15 and limiting grooves arranged side by side. The slots 15 are used to limit the engagement with the carrier plate or lead frame, and the limiting grooves are used to limit the engagement with the placement member 23.

[0042] By setting the slot 15, it can be matched with the carrier plate or lead frame for limiting and cooperating, thereby achieving the purpose of supporting the carrier plate or lead frame for limiting and cooperating; by setting the limiting groove and the limiting groove matching the placement part, the stability of the placement part 23 is improved when the placement part 23 is inserted into the receiving cavity 14.

[0043] Specifically, the material box structure also includes a mounting plate 30, and the material box body 10 has an intercommunicating receiving cavity 14 and a material box opening. The material box opening is used for inserting a carrier plate or lead frame, and the receiving cavity is used to receive the carrier plate or lead frame.
