[0004] To achieve the above objectives, the present invention adopts the following technical solution: a TO-3PF frame strip transfer box, comprising a transfer box body, wherein a plurality of slots are provided on two symmetrical inner walls of the transfer box body, the slots on the two inner walls correspond one-to-one to form an installation area, and there is a height difference between the two corresponding slots;

[0005] Side baffles are slidably connected to both ends of the transfer box body.

[0006] Furthermore, the outer surfaces of both ends of the transfer box body are grooved, and guide rails are provided on the inner end faces of the grooves.

[0007] Furthermore, the side baffle is a semi-open box structure composed of a base plate and three side plates. An observation groove is provided in the middle of the base plate, and raised guide rails are provided on the sides of the two symmetrical side plates.

[0008] Furthermore, the width of the two side plates of the side baffle is equal to the width of the groove of the transfer box body, and the guide rail of the transfer box body is embedded in the protruding guide rail of the side baffle to form a sliding fit.

[0009] Furthermore, the depth of the slots on the inner wall of the transfer box body matches the thickness of the frame strips, and the spacing between the slots on the same side of the inner wall of the transfer box body is greater than the width of the frame strips.

[0010] Compared with the prior art, this utility model has the following advantages: This utility model places the TO-3PF frame strips into the slots of the transfer box. The slots support the upper and lower ends of the frame strips, and there is a certain distance between the slots to ensure that multiple frame strips will not contact or collide. This allows for better loading of products when using the frame strip transfer box of this invention, ensuring the stability of TO-3PF products during transportation. It also solves the problem of batch transfer of TO-3PF frame strip products from the completion of bonding and welding to the pre-sealing stage, reducing contamination and damage during product transfer. At the same time, the side baffles are provided with observation slots, allowing for observation of the transportation status at any time. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0020] TO-3PF packaged product frame strip transfer box structure as follows: Figure 2 and Figure 3 As shown. This includes the frame transfer box body 1, made of aluminum, used to support the frame strips 2, and side retaining strips 3 (see reference). Figure 4 and Figure 5 It is equipped with an observation slot to ensure that the frame will not fall out during the transfer process, and also to facilitate observation of the inside of the transfer box during transportation.

[0021] Instructions for use: Open one side baffle 3, place the TO-3PF plastic-sealed frame strip 2 products in sequence, close the side baffle 3, and a large batch of products can be transported and transferred in one go.

[0022] Example:

[0023] The main body 1 of the transfer box is made of lightweight aluminum and has multiple inclined slots 4 inside. The spacing of the slots 4 is designed according to the size of the frame strips to ensure that adjacent frame strips do not contact each other.

[0024] Side baffles 3: Located on both sides of the transfer box body 1, the outer surfaces of both sides of the transfer box body 1 are grooved, and guide rails are provided on the inner end faces of the grooves. The side baffles 3 are a semi-open box structure formed by an integrated base plate and three side plates. An observation slot is provided in the center of the base plate, and raised guide rails are provided on the symmetrical side edges of the two side plates. The width of the two side plates of the side baffles 3 is equal to the width of the grooves in the transfer box body 1. The guide rails of the transfer box body 1 are embedded in the raised guide rails of the side baffles 3 to form a sliding fit. The side baffles 3 are used to fix the frame strips to prevent them from falling off during transportation.

[0025] Slot 4 structure: The groove depth matches the frame strip thickness, and the frame strip is supported by the upper and lower ends to ensure its vertical stability.

[0026] This transfer box has the following advantages: the 4-slot partition design avoids contact between the frame strips, reducing the risk of product collision damage; the vertical placement of the 2 frame strips reduces the surface contact area, reducing the probability of contamination; it supports loading multiple frame strips at one time, improving batch transfer efficiency; and the vertical arrangement design saves more than 50% of space compared to the flat laying method.

[0027] This utility model mainly optimizes the design of a TO-3PF packaged product frame strip transfer box, which allows for better product loading, ensures the stability of TO-3PF products during transportation, solves the problem of batch transfer of TO-3PF frame strip products from the completion of bonding and wire bonding to the pre-molding stage, and reduces contamination and damage during product transfer.
