Description

Technical Field

[0001] The present invention belongs to the technical field of storage devices, and in particular relates to an anti-deformation storage device for SMT carriers. Background Art

[0002] SMT carriers are auxiliary tools used to carry, fix, position and guide PCB boards and electronic components during the surface mount technology (SMT) production process.

[0003] Currently, nickel sheet SMT carriers use black frames for placement and turnover, but this placement method has many problems. The black frame design causes uneven force on the carrier during placement and turnover, which can damage the small iron sheets and deform the carrier. When personnel take the carrier, due to insufficient clearance between the carriers, it is easy for the carriers to collide or squeeze with each other during operation, further exacerbating the damage and deformation of the carrier. This frequent damage not only increases the cost of repairing and replacing the carrier, but the damage to the small iron sheet of the carrier will also lead to uneven thickness of solder paste printing, which in turn causes problems with printed tin thickness. At the same time, deformation of the carrier will scratch the PCB board, causing copper leakage on the PCB and affecting the conductivity of the circuit. In addition, the falling off of small iron sheets will cause poor solder beads during the soldering process, leading to the risk of short circuits and even causing empty soldering of nickel sheets, affecting the electrical performance of the product. Summary of the Invention

[0004] The purpose of the present invention is to propose an SMT carrier anti-deformation storage device to solve the problem of small iron sheets frequently being damaged, deformed or falling off during the SMT production and storage of nickel sheet machines. This problem not only seriously affects production efficiency but also brings many quality risks.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an anti-deformation storage device for SMT carriers, comprising a storage box, the top and bottom of which are both provided with connectors, the tops and bottoms of several storage boards are both mounted on the connectors and limited by limiting parts, several storage boards and the inner walls of the storage box are surrounded to form several storage slots, the storage boards and the inner walls of the storage box are both provided with several inwardly recessed storage slots, several SMT carriers are located in the storage slots, and the two ends of the SMT carriers are abutted against the storage slots.

[0006] As a further description of the above technical solution:

[0007] There is a gap between the upper and lower SMT carriers.

[0008] As a further description of the above technical solution:

[0009] Both sides of the storage plate located in the middle are provided with storage slots.

[0010] As a further description of the above technical solution:

[0011] The limiting members are located on both sides of the storage plate.

[0012] As a further description of the above technical solution:

[0013] When the connecting body is a screw rod, the limiting member is a limiting nut.

[0014] As a further description of the above technical solution:

[0015] When the connector is a square tube, the limiting member is a limiting ring, the square tube is provided with a plurality of limiting holes, the limiting ring is provided with connecting holes, and the latches pass through the connecting holes in sequence and are connected in the limiting holes.

[0016] As a further description of the above technical solution:

[0017] The top of the storage box is provided with a plurality of limit blocks, and the bottom of the storage box is provided with a plurality of limit slots. When the upper and lower storage boxes are stacked, the plurality of limit blocks correspondingly abut against the plurality of limit slots.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In the present invention, a plurality of connectors are provided at the top and bottom of the storage box, the top and bottom of the storage board are sleeved on the connectors, and limiters are used for positioning. When the SMT carrier needs to be stored, it is only necessary to place the two ends of the SMT carrier in the storage board and the inwardly recessed storage groove of the inner wall of the storage box, and ensure that there is a gap between the SMT carriers to avoid uneven force on the carriers during placement and turnover, thereby avoiding damage to small iron sheets and deformation of the carriers, thereby improving the quality of subsequent PCB board production.

[0020] 2. In the present invention, the storage slots are formed by a plurality of storage plates and the inner wall enclosure of the storage box, and the width between the storage slots can be adjusted by adjusting the position of the limiter connected to the connector, so as to meet the storage requirements of SMT carriers of different widths, and the applicability is strong.

[0021] 3. In the present invention, the limiting member can be set as a limiting nut, and the connecting body can be set as a screw rod. By connecting the limiting nuts to both sides of the storage board, the position of the storage board on the screw rod can be adjusted by adjusting the position of the limiting nuts, thereby adjusting the width between the storage slots, making it suitable for SMT carriers of different sizes and improving applicability.

[0022] 4. In the present invention, the limiting member can be designed as a limiting ring, and the connector can be designed as a square tube. The square tube is provided with a plurality of limiting holes, and the limiting ring is provided with a connecting hole. When adjustment is required, it is only necessary to move the limiting ring to a specific position and insert the pin into the connecting hole and the limiting hole in turn to adjust the width between the storage slots.

[0023] 5. In the present invention, by providing a limit block on the storage box and a limit groove at the bottom of the storage box, this structure can prevent displacement when the storage boxes are stacked up and down, thereby improving the stability of the entire structure during transportation.
