Description

Technical Field

[0001] The utility model relates to the technical field of SMT chip mounting technology, and more specifically, to a feeding device for an SMT mounter. Background Art

[0002] SMT is surface mounting technology (surface mount technology), which is currently the most popular technology and process in the electronic assembly industry. It is a circuit assembly technology that mounts leadless or short-lead surface mount components on the surface of a printed circuit board or other substrates and is soldered and assembled by methods such as reflow soldering or dip soldering.

[0003] Currently, in SMT, electronic components are installed on a PCB board by a mounter. When the mounter installs electronic components on the PCB board, a feeding device is required to supply materials to the mounter. The feeding device continuously supplies electronic components to the mounter. Although most existing feeding devices can continuously supply materials, usually only a small amount of materials can be provided each time, resulting in low work efficiency. Some feeding devices can provide a large amount of materials at one time, but the interval time is long, which also affects the work efficiency. Therefore, the utility model proposes a feeding device for an SMT mounter. Summary of the Utility Model

[0027] In this embodiment, the feeding base 1 supports the blanking plate 5 through the bracket assembly 2. Electronic components enter the two sliding channels 6 through the feeding port 7. The two sliding channels 6 convey the electronic components to the two sets of storage grooves 4 on the two feeding strips 3. The two stoppers 8 control the opening and closing of the two sliding channels 6 through the moving component. When feeding the SMT mounter, the synchronization component controls the two feeding strips 3 to slide in opposite directions on the feeding base 1. When one feeding strip 3 slides downward to the lower side of the blanking plate 5, the moving component moves the two stoppers 8 to open one sliding channel 6, and the electronic components enter a set of storage grooves 4. The two feeding strips 3 both pick up electronic components in the same way. When the feeding strip 3 that has picked up the electronic components moves out from the lower side of the blanking plate 5, the moving component closes the corresponding sliding channel 6. The feeding strip 3 carrying the electronic components moves to one side of the blanking plate 5 to feed the SMT mounter.

[0028] Specifically, the synchronization component includes a first gear 91, a forward and reverse motor 92 and two long racks 93. The first gear 91 is rotatably connected to the top of the feeding base 1. The forward and reverse motor 92 is fixedly connected to the inside of the feeding base 1, and the output end of the forward and reverse motor 92 movably penetrates to the top of the feeding base 1 and is fixedly connected to the bottom end of the first gear 91. The two long racks 93 are respectively fixedly connected to the two storage grooves 4 and are arranged in a staggered manner, and both of the two long racks 93 are meshed with the first gear 91.

[0029] In this embodiment, the forward and reverse motor 92 is electrically connected to an external power source. The forward and reverse motor 92 controls the rotation of the first gear 91. The first gear 91 drives the two long racks 93 to move in opposite directions, so that the two feeding strips 3 move in opposite directions. The feeding strip 3 moving downward to the lower side of the blanking plate 5 receives materials, and the feeding strip 3 moving out from the lower side of the blanking plate 5 feeds the SMT mounter.

[0030] Specifically, the moving component includes a second gear 101, two fixing bars 102, a fixing rod 103, a short rack 104, two springs 105, and a connecting frame 106. The second gear 101 is fixedly connected to the top end of the first gear 91. The two fixing bars 102 are respectively fixedly connected to the symmetric two side ends of the feeding base 1. The fixing rod 103 is fixedly connected between the two fixing bars 102. The short rack 104 is slidably connected to the circumferential surface of the fixing rod 103 and meshes with the second gear 101. The two springs 105 are sleeved on the circumferential surface of the fixing rod 103 and respectively correspond to the symmetric two ends of the short rack 104. The connecting frame 106 is fixedly connected to the bottom end of the short rack 104, and the two stoppers 8 are both fixedly connected to the connecting frame 106.

[0031] In this embodiment, the two fixing bars 102 are used to support the fixing rod 103. When the forward and reverse motor 92 drives the first gear 91 to rotate, the first gear 91 drives the second gear 101 to rotate. The second gear 101 drives the short rack 104 to slide on the fixing rod 103. The short rack 104 drives the two stoppers 8 to move through the connecting frame 106, so that one of the sliding material channels 6 is opened to supply materials to a group of storage grooves 4 on one feeding bar 3. The two springs 105 apply elastic force on the short rack 104 to keep the short rack 104 always meshed with the second gear 101.

[0032] Specifically, two sliding grooves 11 are opened at the top end of the feeding base 1. The bottom ends of the two feeding bars 3 are both fixedly connected with sliders 12, and the two sliders 12 are respectively slidably connected in the two sliding grooves 11.

[0033] In this embodiment, the two storage grooves 4 are slidably connected to the feeding base 1 through the two sliders 12 and the two sliding grooves 11, and move stably on the feeding base 1 to receive and supply materials.

[0034] Specifically, a partition block 13 is fixedly connected inside the feeding port 7, and the partition block 13 corresponds to the two sliding material channels 6.

[0035] In this embodiment, the partition block 13 separates the electronic components entering the feeding port 7, so that the electronic components enter the two sliding material channels 6 respectively for feeding.

[0036] Working principle: The electronic components are placed into the feeding port 7 and conveyed through two sliding material channels 6 into two groups of storage slots 4 on two feeding bars 3. The forward and reverse motor 92 controls the rotation of the first gear 91 and the second gear 101. The first gear 91 drives the two long racks 93 to drive the two feeding bars 3 to move in opposite directions. When any one of the feeding bars 3 moves to the lower side of the blanking plate 5, the second gear 101 drives the connecting frame 106 to move through the short rack 104. The two springs 105 keep the short rack 104 always meshed with the second gear 101, so that the connecting frame 106 drives the two stoppers 8 to move to open one of the sliding material channels 6. The opened sliding material channel 6 corresponds to the feeding bar 3 moving to the lower side of the blanking plate 5, so as to feed one group of storage slots 4. After the feeding is completed, the forward and reverse motor 92 controls the first gear 91 and the second gear 101 to rotate in the reverse direction, so that the other feeding bar 3 moves to the lower side of the blanking plate 5. The short rack 104 drives the connecting frame 106 to move in the reverse direction, and the two stoppers 8 open the other sliding material channel 6, so as to feed the other group of storage slots 4. At the same time, the feeding bar 3 that has received the materials moves out from the lower side of the blanking plate 5 and feeds the SMT mounter.

[0037] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
