[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] Reference Figure 1 This utility model provides a loading and unloading auxiliary device, including a support platform 1 configured in conjunction with a pre-burning furnace 4, and an antistatic mechanism 2 installed on the support platform 1. The platform 1 has an antistatic dissipation area for holding chips, and the antistatic mechanism 2 can remove static electricity from the chips located in the antistatic dissipation area. After the chips undergo aging tests, the chips can be removed from the pre-burning furnace 4 and placed on the support platform 1, and then the antistatic mechanism 2 can dissipate static electricity from the chips to reduce the risk of static electricity damage.

[0027] Reference Figure 1 and Figure 2 In this embodiment, the static eliminator 2 includes a first ion fan 21 mounted on the support platform 1. The first ion fan 21 is tilted so that its airflow direction is towards the static dissipation area. Therefore, the first ion fan 21 can effectively eliminate static electricity from the chips placed in the static dissipation area. In this embodiment, the static dissipation area is adjacent to the operating end of the support platform 1 relative to the static eliminator 2, so as to facilitate the operation and transfer of chips in the pre-burning furnace to the static dissipation area by relevant personnel.

[0028] Reference Figure 1There are two support platforms 1, located on either side of the pre-burning furnace 4, used to hold good products and defective products respectively. Each support platform 1 is equipped with an anti-static mechanism 2. After the chip aging test, good products and defective products can be placed on the two support platforms 1 respectively, thus avoiding mixing of materials.

[0029] Reference Figures 1 to 3 The height of the two supporting platforms 1 is the same as the height of the preset position of the lifting frame 422 of the pre-fired furnace 4. The preset position is the target height position for placing and removing the pre-fired plate on the lifting frame 422. When the pre-fired plate is placed or removed to the target height position via the lifting frame 422, the operator can work on the pre-fired plate, which is equivalent to the pre-fired plate being placed or removed to the ready-to-operate position (e.g., ...). Figure 3 (As shown).

[0030] It should be noted that, referring to Figures 2 to 3 The pre-burning furnace 4 typically includes a furnace body 41 for high-temperature heating of the chips, and a pre-burning plate lifting mechanism 42 installed in conjunction with the furnace body 41. The pre-burning plate lifting mechanism 42 includes a lifting assembly 421 and a lifting frame 422. The lifting assembly 421 can drive the lifting frame 422 to rise or fall. The lifting assembly 421 can be configured as a pulley system, which drives the lifting frame 422 to move. Figure 3 and Figure 4 When the lifting assembly 421 drives the lifting frame 422 to rise, it can lift the pre-burned plate (such as...) located on the lifting frame 422. Figure 4 The chip on the pre-burning board (as indicated by mark a) is pushed into the furnace body 41 to perform a high-temperature aging test. After the pre-burning board is removed from the furnace body 41 and placed into the lifting frame 422, the lifting frame 422 can be driven down to a preset position by the lifting assembly 421. At this time, the operator can transfer the chip to the static dissipation area.

[0031] Reference Figure 1 and Figure 2 Furthermore, the static elimination mechanism 2 also includes a second ion fan 22 mounted on the support platform 1. The second ion fan 22 is placed at an angle so that its airflow direction is towards the loading and unloading ends of the pre-calcining furnace 4. The first ion fan 21 and the second ion fan 22 do not interfere with each other. The loading and unloading ends of the pre-calcining furnace 4 are located at the position of the lifting frame 422 in a preset position (e.g., ...). Figure 3 (As shown). By setting a second ion fan 22, static electricity can be dissipated from the chips located on the pre-burning board in a timely manner to prevent static electricity risks. In this embodiment, combined with Figure 3 Both support platforms 1 are equipped with second ion fans 22. The air blowing directions of the two second ion fans 22 are set opposite to each other and both face the lifting frame 422 at the preset position.

[0032] Reference Figure 2The support platform 1 is equipped with an electrostatic discharge port, which can be grounded through a grounding wire to ensure effective electrostatic discharge of the chip.

[0033] Reference Figure 1 and Figure 2 The loading and unloading auxiliary device in this embodiment also includes an auxiliary table 3. The support platform 1 is the tabletop of the auxiliary table 3, and a support plate 31 is provided inside the auxiliary table 3 for temporarily placing trays. In this embodiment, one pre-burning furnace 4 is provided with two auxiliary tables 3 for placing good and defective chips. The auxiliary table 3 is provided with two layers of support plates 31 for temporarily placing trays, but this is not a limitation on the number of support plates 31. In other embodiments, other numbers of support plates 31 can be used, such as one, three, or four. By providing support plates 31 inside the auxiliary table 3, the time for operators to retrieve trays can be saved, thus improving work efficiency.

[0034] Reference Figure 1 In one embodiment of this utility model, a pre-firing furnace system is also provided, including a pre-firing furnace 4 and a loading and unloading auxiliary device as described above, which cooperates with the pre-firing furnace 4. It is understood that the pre-firing furnace system equipped with the aforementioned loading and unloading auxiliary device can not only dissipate static electricity for the chips to reduce the risk of static electricity, but also distinguish between good and defective products to prevent mixing.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
