Description

Technical Field

[0001] The utility model relates to a feeder pressing device for a chip mounter, which is used for fixing and assisting in conveying a material belt of the chip mounter. Background Art

[0002] In the process of stripping the tape, the existing SMT machine uses a feeder pressing device to press the tape and strip the film on the tape. Because the placement speed of the SMT machine is very fast, the feeding requirements are both accurate and fast. However, the existing SMT machine feeder pressing device is often complex in structure, high in cost, and difficult to adjust. It is impossible to adjust the stripping mechanism for the tape of corresponding thickness, resulting in low adaptability. In addition, the stripping structure is not easy to disassemble and install, which often leads to shutdown problems when components are damaged.

[0003] For example, a Chinese patent with a patent publication number of CN215379366U discloses a material tray limiting mechanism of a placement machine, which is applied to the placement machine. The material tray limiting mechanism of the placement machine includes a support shaft for supporting a material tape roll, the material tape roll is sleeved outside the support shaft, and the support shaft is rotatably connected to the placement machine. During use, one end of the material tape of the material tape roll is installed into the placement machine. At this time, the placement machine will pull the material tape, and the material tape can drive the support shaft to rotate relative to the placement machine, so that the material tape gradually moves into the placement machine; at this time, since the support shaft is rotatably connected to the placement machine, the position stability of the support shaft is relatively high, achieving the purpose of improving the structural stability of the material tray limiting mechanism.

[0004] However, the solution of the patent has the problem that it is not easy to replace new material belts, and it is not good for supporting material belts of different specifications and thicknesses. Moreover, the speed of replacing material belts is slow and the adaptability is poor. Summary of the invention

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the embodiments. The following embodiments are intended to explain the present invention but the present invention is not limited to the following embodiments.

[0030] Embodiment 1:

[0031] like Figures 1 to 5 As shown, this embodiment describes a feeder pressing device for a chip mounter, which is arranged on a feeder of the chip mounter, and is used to press the material belt of the chip mounter and assist the normal movement of the material belt. The feeder pressing device for the chip mounter is composed of.

[0032] The stainless steel pressing plate 1 is composed of a mutually perpendicular side plate 13, a top plate 14 and a bottom plate 18. The bottom plate 18 is at the bottom, and the side plate 13 connects the bottom plate 18 and the top plate 14. A structural opening 17 is provided on the side plate 13, which reduces weight and saves materials on the one hand, and also strengthens the strength of the stainless steel pressing plate 1 on the other hand. A material belt opening 15 and a material discharge opening 16 are provided on the top plate 14. The top plate 14 cooperates with the limiting surface 9 above the flyer base 5.

[0033] The bottom of the stainless steel pressing plate 1 is matched with the flyer base 5 through the fixing structure 8 and the support spring 6. A vertical bar-shaped pressing plate mounting hole 12 is provided on the side of the flyer base 5, and the side of the stainless steel pressing plate 1 is mounted on the flyer base 5 through the flat head screw 7. The support spring 6 and the flyer base 5 cooperate with each other. The elastic pad 3 and the pad spring 4 are flexibly installed on the flyer base 5, located below the top plate 14, and the bottom end of the elastic pad 3 is provided with a connection structure that cooperates with the pad spring 4.

[0034] During the process of feeding the material belt and changing the material belt, the support spring 6 is manually compressed and deformed to bounce the stainless steel pressure plate 1 upward. When loading the material belt, the hole on the material belt passes through the gear teeth of the ratchet 2. When the ratchet 2 rotates, it drives the material belt forward to realize the feeding function of the material belt. When the support spring 6 recovers its deformation, the stainless steel pressure plate 1 and the elastic pad 3 interact with each other to fix the material belt, so that the material belt will not shake up and down during feeding. The elastic pad 3 fixes its own position through the positioning hole 10 on the feeder base 5, and can also manually adjust the adjustment hole 11 on the elastic pad 3 to adapt to the thickness of different types of material belts. In addition, when the elastic pad 3 is fixed, it can adapt to different types of material belts under the action of the self-elastic force of the pad spring 4, and the left and right limit surfaces 9 on the feeder base 5 can limit the material belt to the left and right to prevent the material belt from moving left and right, so as to realize the stable operation of the feeder feeding.

[0035] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different. All equivalent or simple changes made based on the structure, features and principles described in the concept of the utility model patent are included in the protection scope of the utility model patent. The technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar way, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
