[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0028] First Embodiment
[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 A schematic diagram of the first embodiment of a safety-type hollow lead frame carrier box structure with a locking device provided by this utility model; Figure 2 for Figure 1 The diagram shows a top view of the main body of the carrier box. Figure 3 for Figure 1 The diagram shows the side structure of the main body of the carrier box; Figure 4 for Figure 1 The diagram shows the end face structure of the carrier box body.
[0030] Figure 5 for Figure 1 The diagram shown is a top view of the carrier lid structure. Figure 6 for Figure 1 The diagram shows the structure of the locking device when it is locked. Figure 7This is a schematic diagram of a lead frame carrier structure in the prior art provided by this utility model. A safety-type hollow lead frame carrier structure with a locking device includes: a carrier body 1, a carrier cover 2, a locking device 3, and a QR code identification slot 4. The carrier cover 2 is respectively disposed at both ends of the carrier body 1, and the locking device 3 and the QR code identification slot 4 are both disposed at the top of the carrier body 1.
[0031] The locking device 3 includes a locking device cover 31 and a locking device lever 32. The locking device lever 32 is slidably connected to the inner side of the locking device cover 31, and the bottom of the locking device cover 31 is connected to the bottom of the carrier body 1.
[0032] The two ends of both sides of the main body 1 of the carrier box are provided with sliding grooves 11, and the end face of the cover 2 of the carrier box is slidably connected to the inner side of the sliding grooves 11.
[0033] Multiple fabric grooves 13 are provided on both sides of the inner side of the carrier body 1.
[0034] The side of the carrier body 1 is provided with a hollow strip hole 12.
[0035] The side of the carrier cover 2 has a through hole 21.
[0036] The bottom of the locking lever 32 abuts against the top of the carrier cover 2.
[0037] The lead frame carrier body 1 has an external length of 256mm, a width of 86.5mm, a height of 127mm, and an internal width of 70.2mm. The carrier body 1 contains 13 material slots, each 1.4mm high and 5.15mm deep, with a spacing of 5.21mm between adjacent slots. It can support up to 20 lead frames. The top of the carrier body 1 has chamfered rectangular openings at both ends of the short side, each 50mm long and 6mm wide. The sides of the carrier body 1 have perforated strip holes parallel to the direction of the material strips being carried. 2. Each side has 19 rows and 2 columns, with holes 102mm long and 2mm wide. The short side of the strip holes has a 1mm radius rounded corner. The top of the main body 1 of the carrier box has an inwardly recessed QR code label groove 4 with an area of 15mm*15mm. The top of the main body 1 of the carrier box has a locking device 3, which is lower than the top side wall, making it less prone to damage and not affecting the stacking of multiple carrier boxes. The locking device 3 is composed of a locking device cover plate 31 and a locking device lever 32. When the locking device is active, it can prevent the carrier box cover 2 from sliding up and down.
[0038] The main body 1 of the carrier box increases the distance between adjacent material feeding grooves 13, eliminates the bottom opening and reduces the area of the top rectangular hole, reducing the risk of material jamming on the machine and accidental contact with the material inside the carrier box by personnel, which could lead to material contamination and collapse of the guide wire.
[0039] The main body height was reduced, and side perforated strip holes 12 were added. This reduced the weight of the carrier box while ensuring its strength and protection, thus improving material transportation efficiency. The addition of side perforated strip holes 12 improved the heat uniformity of the carrier box during the baking process, enhanced hot air flow, and prevented moisture and volatiles from accumulating in the cavity and contaminating the material. The addition of side perforated strip holes 12 also allowed the carrier box to be directly placed into the cavity-type plasma cleaner for cleaning, greatly improving cleaning efficiency and avoiding the risk of material damage caused by manual / mechanical material removal during the cleaning process.
[0040] The top of the main body 1 of the carrier box is equipped with a QR code marking slot 4, which can be laser printed with QR codes. With the help of a smart handheld terminal, the QR code can be scanned for traceability, enabling refined control of materials. The QR code placement area is recessed inward to avoid wear and failure of the QR code.
[0041] The working principle of the safety-type hollow lead frame carrier box structure with locking device provided by this utility model is as follows:
[0042] The lead frame is placed inside the carrier body 1 and protected by the cushioning fabric in the fabric groove 13. The carrier cover 2 is installed onto the carrier body 1 via the slide groove 11, ensuring a tight fit. When locking the carrier, push the locking lever 32 so that its bottom abuts against the top of the carrier cover 2, thereby restricting the upward movement of the carrier cover 2 and completing the locking operation. To open the carrier, push the locking lever 32 in the opposite direction to disengage it from the top of the carrier cover 2. During material management, a QR code containing detailed material information is printed in the QR code identification slot 4 using a laser printer. Staff can use a smart handheld terminal to scan the code to obtain material information, enabling material traceability management.
[0043] Compared with related technologies, the safety-type hollow lead frame carrier structure with a locking device provided by this utility model has the following advantages:
[0044] With the locking device 3 in use, one side of the locking device tweezers 32 can abut against the top of the carrier lid 2, thereby limiting the carrier lid 2 and preventing it from sliding, thus preventing materials from falling out during transportation.
[0045] Furthermore, with the QR code identification slot 4, staff can use smart handheld terminals to scan the code for traceability and implement refined management of materials.
[0046] Second Embodiment
[0047] Please refer to the following: Figure 8Based on the first embodiment of this application which provides a safety-type hollow lead frame carrier box structure with a locking device, the second embodiment of this application proposes another safety-type hollow lead frame carrier box structure with a locking device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0048] Specifically, the second embodiment of this application provides a safety hollow lead frame carrier structure with a locking device, which differs in that the safety hollow lead frame carrier structure with a locking device further includes a first positioning member 5 and two second positioning members 6. The first positioning member 5 is embedded in the top of the inner side of the locking device cover 31, and the two second positioning members 6 are embedded in the top of the locking device lever 32.
[0049] Both the first positioning element 5 and the second positioning element 6 can be made of magnetic metal, so that they can be magnetically attracted to each other during use, thereby playing a limiting role.
[0050] The working principle of the safety-type hollow lead frame carrier box structure with locking device provided by this utility model is as follows:
[0051] When in use, when the locking lever 32 is pushed out so that the bottom of one end of the locking lever 32 abuts against the top of the carrier cover 2, the first positioning member 5 will be magnetically attracted to one of the second positioning members 6, thereby limiting the locking lever 32.
[0052] When it is necessary to release the lock, move the lock lever 32 toward the inner side of the lock cover 31. At this time, the first positioning member 5 will be magnetically attracted to the other second positioning member 6.
[0053] Compared with related technologies, the safety-type hollow lead frame carrier structure with a locking device provided by this utility model has the following advantages:
[0054] The first positioning element 5 and the second positioning element 6 work together to limit the locking lever 32 during use, preventing the locking lever 32 from moving arbitrarily and increasing the stability of the locking lever 32 during use.
[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
