Description

Technical Field

[0001] The utility model relates to the technical field of surface mounting, in particular to an SMT automatic loading and unloading plate fixture. Background Art

[0002] On the current SMT production line, the loading and unloading process of package substrates mainly relies on manual operation, which has problems such as low efficiency, large errors, high labor intensity and poor consistency. The loading and unloading process is one of the key links in production efficiency and product quality, especially in the ball grid array packaging industry. Accurate and rapid loading and unloading is crucial to maintaining the continuity of the production process and reducing operation time.

[0003] In the current operation process, a steel plate is used as a carrier, the package substrate is manually placed on the steel plate, and the pins on the steel plate are aligned with the openings on the substrate, and then the substrate is fixed with high-temperature tape. This process is not only time-consuming and labor-intensive, but also has the following significant problems: First, the manual alignment pins are prone to position deviation, resulting in inaccurate substrate fixation, which in turn affects the accuracy of subsequent processes and the quality of the final product; second, the high-temperature tape fixation method has the problem of unstable fixation, which may cause the substrate to loosen or shift during processing due to environmental factors; in addition, the high-temperature tape needs to be manually removed after unloading, and this process is prone to produce residual glue, which affects the surface quality of the substrate and subsequent processes, and increases the difficulty of cleaning and production costs; repetitive manual work is not only inefficient, but also increases the labor intensity and fatigue of the operator, further increasing the probability of error; the consistency difference of manual operation also affects the consistency and reliability of production, so an SMT automatic loading and unloading carrier fixture is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an SMT automatic loading and unloading plate carrier fixture, including a positioning plate, a magnet is fixed to the surface of the positioning plate, the upper end of the magnet is connected to a magnetic steel sheet, a positioning pin is fixed to the upper end of the magnetic steel sheet, and a groove is provided in the middle of the positioning plate.

[0006] Preferably, the surface of the positioning plate is provided with positioning grooves, and the positioning grooves and positioning pins are located at the four corners of the magnetic steel sheet and the positioning plate.

[0007] Preferably, a connection is fixed at the lower end of the positioning plate, and a base is fixed at the lower end of the connection.

[0008] Compared with the related art, the SMT automatic loading and unloading plate fixture provided by the utility model has the following beneficial effects:

[0009] The utility model realizes automatic loading of packaging substrates through a manipulator or a transmission device, a precise positioning device ensures accurate alignment of the substrate, and a magnetic steel sheet fixing technology replaces the high-temperature tape, thereby realizing rapid, stable fixation of the substrate and no residual glue pollution; the carrier jig is transmitted on the track to ensure stable movement and precise positioning of the packaging substrate in the production line. This automated device greatly reduces manual intervention, improves loading and unloading speeds and overall production efficiency, and the magnetic steel sheet fixing method is not only highly reliable and unaffected by environmental factors, but also convenient for rapid disassembly and assembly, improves operational convenience and stability, avoids the problem of residual glue after the removal of the high-temperature tape, and ensures the surface quality of the substrate and the smooth progress of subsequent processes; automated operation significantly reduces the labor intensity of operators, reduces fatigue, and improves the comfort of the working environment; the highly consistent operation of the automated equipment ensures consistent fixing effects for each substrate, thereby improving the stability and reliability of product quality.

[0013] Example, by Figure 1-2 It is given that the utility model includes an SMT automatic loading and unloading plate fixture, including a positioning plate 6, a magnet 8 is fixed to the surface of the positioning plate 6, the upper end of the magnet 8 is connected to a magnetic steel sheet 1, a positioning pin 7 is fixed to the upper end of the magnetic steel sheet 1, and a groove 2 is provided in the middle of the positioning plate 6.

[0014] The surface of the positioning plate 6 is provided with positioning grooves 5 , and the positioning grooves 5 and the positioning pins 7 are all located at the four corners of the magnetic steel sheet 1 and the positioning plate 6 .

[0015] A connection part 3 is fixed to the lower end of the positioning plate 6 , and a base 4 is fixed to the lower end of the connection part 3 .

[0016] The magnetic fixing mechanism of the jig includes an embedded magnet 8 and a magnetic steel sheet 1 that is bonded to the surface of the jig. This design eliminates the need for traditional high-temperature tape, quickly and stably locks the substrate through magnetic force, improves the reliability of fixation, and avoids damage and cleaning problems on the substrate surface. During the automatic loading and unloading process, the jig is first transported to the loading area together with the magnetic steel sheet 1, and then the suction nozzle of the loading mechanism first sucks up the magnetic steel sheet 1 and places it on the surface of the jig. The push rod pushes the substrate out of the magazine and is sucked up by the suction nozzle and accurately placed on the jig. After the positioning hole of the substrate is accurately docked with the positioning pin 7 of the jig, the loading mechanism re-places the magnetic steel sheet 1 on the top of the jig to fix the substrate through magnetic force.

[0017] A groove 2 is provided in the middle area of ​​the jig to speed up the efficiency of high-temperature fixation of electronic components after they are soldered to the substrate via reflow soldering, and is also conducive to the subsequent deep cleaning of the jig; at the same time, the front and back dug areas are chamfered to reduce the number of products with sharp corners and avoid affecting manual operations.

[0018] After the jig is loaded, it is automatically transferred to the work area along a 1.3mm deep track for SMT processing. After the operation is completed, the unloading mechanism uses a similar mechanism to remove the substrate from the jig and transfer it to the unloading magazine, while the empty jig is automatically recovered to the loading area, ready for the next round of automatic loading and transfer, achieving efficient recycling.
