Description

Technical Field

[0001] The utility model relates to the technical field of SMT patches, in particular to an SMT patch conveying device. Background Art

[0002] SMT is surface assembly technology, which is the most popular technology and process in the electronic assembly industry. The surface assembly technology of electronic circuits is called surface mounting or surface installation technology. SMT patch refers to the abbreviation of a series of process flows based on PCB. PCB is a printed circuit board, which is the most popular technology and process in the electronic assembly industry. In the above-mentioned process of patch processing on PCB circuit boards, a conveying device is needed to convey the PCB circuit boards to improve the processing efficiency of the PCB circuit boards. However, the existing conveying device lacks a corresponding limiting mechanism, which makes the PCB circuit boards easy to fall from the conveying device, seriously affecting the processing efficiency of the PCB circuit boards.

[0003] For example, a conveying device for SMT patch processing disclosed in a Chinese patent document (publication number: CN220068181U) has a pillar that is clamped into a clamping slot. At this time, the slider is driven to slide in the sliding slot under the action of the elastic force of the compression spring. When the clamping strip on the top of the slider is clamped into the clamping slot on the outer wall of the pillar, the pillar can be limited and fixed. In addition, since L-shaped limit strips are provided on the outer walls on both sides of the pillar, the two L-shaped limit strips can limit the PCB board on the conveyor belt to prevent the PCB board from falling from the conveyor belt during the conveying process. On the one hand, it avoids damage to the PCB board and improves the processing safety of the PCB board. On the other hand, it improves the processing efficiency of the PCB board.

[0004] However, in the implementation of the above scheme, since the PCB circuit boards need to be transported individually, it is necessary to manually place the PCB circuit boards on the surface of the conveyor belt one by one for transportation. Long-term repetitive actions can easily cause work fatigue to the workers, which not only greatly increases the manual labor force, but also easily leads to the problem of reduced PCB circuit board transportation efficiency.

The observation slot 5 is not only convenient for observing the PCB circuit board surplus inside the storage shell 4, but also convenient for stacking the PCB circuit boards inside the storage shell 4, a discharge port 6 is opened on one side surface of the storage shell 4, and a push slot 7 is opened on the lower surface of the storage shell 4, and one end of the push slot 7 is communicated with the inner bottom wall of the discharge port 6;

[0025] An automatic material pushing and conveying device is provided on one side surface of the storage shell 4, and the automatic material pushing and conveying device includes a material guide plate 8, and baffles are provided on both sides of the material guide plate 8 to prevent the PCB from falling during the unloading process. One end of the material guide plate 8 is fixedly connected to the one side surface of the storage shell 4.

[0026] A servo motor 81 is fixedly installed on one side surface of one of the support blocks 3, and a rotating shaft 82 is fixedly installed on the output shaft of the servo motor 81 through a coupling. One end of the rotating shaft 82 passes through and extends to the other side surface of one of the support blocks 3, and one end of the rotating shaft 82 is fixedly connected to a rotating sleeve 83. The servo motor 81 drives the rotating sleeve 83 to position and rotate through the rotating shaft 82. A moving rod 84 is movably sleeved on the inner wall of the rotating sleeve 83, and one end of the moving rod 84 is fixedly connected to a connecting seat 85. A contraction spring 86 is movably sleeved on the outer surface of the moving rod 84. The rotation of the rotating sleeve 83 is coordinated with the connecting seat 85 and the contraction spring 86 to cooperate with the moving rod 84 to move. One end of the contraction spring 86 is fixedly connected to the lower surface of the rotating sleeve 83, and the other end of the contraction spring 86 is fixedly connected to the upper surface of the connecting seat 85. A movable rod 87 is installed on one side surface of the connecting seat 85 through a bearing.

[0027] One end of the movable rod 87 is fixedly connected to a lifting block 88, and the inner wall of the lifting block 88 is movably sleeved with a guide rod 89. The guide rod 89 guides the lifting and lowering movement of the lifting block 88. One end of the guide rod 89 is fixedly connected to a moving sleeve 810, and the inner wall of the moving sleeve 810 is movably sleeved with a positioning rod 811. The positioning rod 811 guides the movement of the moving sleeve 810 and limits the stroke. Both ends of the positioning rod 811 are fixedly connected to symmetrically distributed fixed blocks 812. The lower surfaces of the two fixed blocks 812 are fixedly connected to the upper surface of the base 1. One side surface of the lifting block 88 is fixedly connected to a mounting plate 813, and the upper surface of the mounting plate 813 is fixedly connected to a push plate 814. The movement of the lifting block 88 drives the push plate 814 to move synchronously through the mounting plate 813.

[0028] By setting up an automatic pushing and conveying device, the PCB circuit boards can be automatically unloaded and conveyed in pieces, avoiding the fatigue caused by repeated manual placement. This not only reduces manual labor but also improves the conveying efficiency.

[0029] Working principle: Step 1, the staff places the stacked PCB circuit boards inside the storage shell 4. The observation slot 5 is not only convenient for observing the remaining PCB circuit boards inside the storage shell 4, but also convenient for stacking the PCB circuit boards inside the storage shell 4. During transportation, the servo motor 81 is started to work, and the servo motor 81 drives the rotating sleeve 83 to rotate through the rotating shaft 82. However, when the rotating shaft 82 rotates ninety degrees, the rotation of the rotating sleeve 83 drives the connecting seat 85 at one end thereof to move through the moving rod 84. The movement of the connecting seat 85 drives the lifting block 88 to move upward through the cooperation of the guide rod 89 and the movable rod 87, and at the same time, the lifting block 88 is driven to move to one side through the cooperation of the positioning rod 811 and the moving sleeve 810;

[0030] Step 2, when the rotating shaft 82 continues to rotate, the lifting block 88 moves in the opposite direction through the cooperation of the positioning rod 811 and the movable sleeve 810, and the elastic force of the contraction spring 86 is used to increase the driving force of the lifting block 88 during translation. The movement of the lifting block 88 drives the upper end of the push plate 814 to move to the inside of the pushing groove 7 through the mounting plate 813, and drives the bottom PCB circuit board inside the storage shell 4 to be pushed through the push plate 814. When the rotating shaft 82 rotates to two hundred and seventy degrees, its PCB circuit board is pushed out through the discharge port 6 and transported to the top of the conveying mechanism body 2 through the guide plate 8 for conveying. At this time, the rotating shaft 82 has completed one circle of rotation, and the PCB circuit boards stacked on the top move downward, waiting to be pushed out and conveyed.
