Description

Technical Field

[0001] The present invention relates to the field of SMT material receiving machines, and more specifically, to a carrier tape supporting mechanism and a supporting method. Background Art

[0002] SMT is the abbreviation of surface mount technology (surface mount technology), which is the most popular technology and process in the electronic assembly industry. Surface mount technology of electronic circuits (Surface Mount Technology, SMT) is called surface mount or surface mounting technology. It is a circuit assembly technology that mounts pinless or short-lead surface mount components (abbreviated as SMC / SMD, called sheet components in Chinese) on the surface of printed circuit boards (Printed Circuit Board, PCB) or other substrates, and assembles them by soldering through reflow soldering or dip soldering. At present, the materials are all spliced ​​by automatic splicing machines on the market. The carrier tape is placed on the carrier tape support on the flow channel, and the automatic splicing machine fits and connects the carrier tape on the carrier tape support through the splicing tape. Because there are many specifications for carrier tape thickness, the thinnest carrier tape is about 0.25mm thick. During the automatic splicing process, the carrier tape needs to be supported to prevent it from sagging, which will cause the splicing piece to fail to wrap around the edge during the splicing process. However, if the carrier tape support is always present, it will hinder the wrapping of the splicing piece, which is not conducive to the completion of automatic splicing. Summary of the invention

[0017] Figure 2 It is a schematic diagram of a carrier support mechanism of the present invention in which the second support block moves upward and the third support block sinks downward. DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner. The direction of this specific implementation is to Figure 1 Direction is standard.

[0019] like Figure 1 , Figure 2 As shown, a carrier tape support mechanism is arranged at a flow channel 7 for carrying a carrier tape, and the carrier tape support mechanism includes a first support block 1, a second support block 2, and a third support block 3 arranged in sequence for supporting the carrier tape, the second support block 2 is connected to a first driving structure 4 for driving the second support block 2 to support the carrier tape, and the third support block 3 is connected to a second driving structure 5 for driving the third support block 3 to support the carrier tape, and the second support block 2 and the third support block 3 can alternately support the carrier tape. The first support block 1 is arranged on the opposite support side of the carrier tape traction hole side support side, the second support block 2 is arranged below the carrier tape and opposite to the protruding part of the carrier tape, and the third support block 3 is arranged on the carrier tape traction hole side support side. When conveying the carrier tape, the second support block 2 needs to sink to avoid the raised part of the carrier tape, because the raised part of the carrier tape is generally components. If the second support block 2 keeps supporting it, it will cause wear of the components and hinder the conveyance of the carrier tape; when the carrier tape needs to be edged by the splicing tape, the third support block 3 needs to sink to avoid the structure of the automatic splicing machine used for edge wrapping, and at the same time, the second support block 2 needs to move up to support the carrier tape to prevent the carrier tape from sinking.

[0020] The first driving structure 4 includes a first connecting member 41 and an electromagnet 42. One end of the first connecting member 41 is connected to the second supporting block 2, and the other end of the first connecting member 41 is connected to the electromagnet 42.

[0021] The second support block 2 is driven by an electromagnet 42, and the electromagnet 42 drives the second support block 2 to generate a support force on the carrier tape that is not too large, about 5 N. Because the height of the raised portion of the bottom surface of the carrier tape is 0-3.0 mm, the second support block 2 needs to be able to support all the carrier tapes in this range. If the force is too large, the raised portion of the carrier tape will be pressed and deformed, further causing the electronic components in the carrier tape to be compressed and deformed.

[0022] The second driving structure 5 includes a second connecting member 51 and a driving motor 52. One end of the second connecting member 51 is connected to the third support block 3, and the other end of the second connecting member 51 is connected to the driving motor 52.
