Description

Technical Field

[0001] This utility model relates to the field of riveting devices, and in particular to an automatic feeding riveting device. Background Technology

[0002] In the fields of electronics and electrical appliances, riveting is an important connection process. Due to its characteristics of strong connection, convenient operation and low cost, it is widely used in the assembly process of various products. Traditional riveting operations usually rely on manual labor, that is, the operator manually places the rivet in the preset position of the workpiece to be riveted, and then uses riveting equipment such as pneumatic rivet guns and hydraulic riveting machines to squeeze and deform the rivet to achieve the connection of the workpiece.

[0003] Traditional riveting relies on manual handling of rivets, which is repetitive and time-consuming, resulting in a slow production pace that is difficult to adapt to the needs of mass production. In addition, during the traditional riveting process, operators need to be in close contact with the riveting equipment, and their hands may be pinched by the pressing and closing of the equipment, posing a safety risk.

[0004] In response to the technical problems of low efficiency and safety risks associated with traditional riveting relying on manual handling of rivets, this application proposes an automatic feeding riveting device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of traditional riveting methods, which rely on manual handling of rivets, resulting in low efficiency and safety risks. This invention proposes an automatic feeding riveting device that automatically feeds materials via a vibrating feeder and uses a cylinder to lower the mounting plate, causing the upper die to press down on top of the lower die. This achieves automatic feeding and riveting, replacing manual labor, saving time, and improving efficiency. Furthermore, the light gratings installed on both sides provide protection for workers, preventing hand pinching.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding riveting device, comprising a base plate, with support columns fixedly connected to the top four sides of the base plate, a top plate fixedly connected to the top of the support columns, a cylinder fixedly connected to the top of the top plate, a mounting plate fixedly connected to the driving end of the cylinder, an upper mold provided at the bottom of the mounting plate, four threaded holes opened at the top of the upper mold, four fasteners installed on the inner wall of the mounting plate, the fasteners being detachably connected to the threaded holes, a lower mold fixedly connected to the top of the base plate, guide shafts fixedly connected to the four corners of the top of the lower mold, and the inner wall of the upper mold slidably connected to the outer wall of the guide shafts.

[0007] Furthermore, a material vibration plate is provided at the left end of the base plate, and a guide rail is installed on the inner wall of the material vibration plate, which drives the other end of the guide rail to be located above the base plate.

[0008] Furthermore, a vibratory feeder sensor is installed on the guide rail to sense whether the guide rail is full of material.

[0009] Furthermore, a linear vibrator is provided at the left end of the base plate, and a control box is fixedly connected to the top of the linear vibrator.

[0010] Furthermore, safety light curtains are fixedly connected to both the left and right ends of the front top of the base plate to protect the hands.

[0011] Furthermore, two control switches are installed on the front side of the top of the base plate to control the start and stop of the cylinder.

[0012] This utility model has the following beneficial effects: In this invention, a vibratory feeder automatically supplies materials, and a cylinder drives the mounting plate downwards, causing the upper mold to press down on top of the lower mold. This achieves automatic material feeding and riveting, replacing manual labor, saving time, and improving efficiency. Furthermore, the light gratings installed on both sides protect workers from hand pinching. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-3An embodiment of this utility model provides an automatic feeding riveting device, comprising a base plate 1, with support columns 6 fixedly connected to the four sides of the top of the base plate 1, a top plate 8 fixedly connected to the top of the support columns 6, a cylinder 9 fixedly connected to the top of the top plate 8, a mounting plate 15 fixedly connected to the driving end of the cylinder 9, an upper mold 7 provided at the bottom of the mounting plate 15, four threaded holes opened at the top of the upper mold 7, four fasteners 16 installed on the inner wall of the mounting plate 15, the fasteners 16 being detachably connected to the threaded holes, a lower mold 4 fixedly connected to the top of the base plate 1, guide shafts 5 fixedly connected to the four corners of the top of the lower mold 4, and the inner wall of the upper mold 7 sliding. A material vibrating plate 11 is installed on the left end of the base plate 1, connected to the outer wall of the guide shaft 5. A guide rail 14 is installed on the inner wall of the material vibrating plate 11, which drives the other end of the guide rail 14 to be located above the base plate 1. A vibrating plate sensor 12 is installed on the guide rail 14 to sense whether the material on the guide rail 14 is full. A linear vibrator 13 is installed on the left end of the base plate 1. A control box 10 is fixedly connected to the top of the linear vibrator 13. Safety light curtains 3 are fixedly connected to both the left and right ends of the top front side of the base plate 1 to protect the hands. Two control switches 2 are installed on the top front side of the base plate 1 to control the start and stop of the cylinder 9.

[0017] Specifically, two transverse grooves are provided on both the front and rear sides of the mounting plate 15. Fasteners 16 are located on the inner wall of the transverse grooves, and the top part of the fasteners 16 is larger than the width of the transverse grooves. The fasteners 16 can move within the transverse grooves, thereby allowing the position of the upper mold 7 to be adjusted when the lower mold 7 is installed. When the cylinder 9 drives the upper mold 7 to move downward, the upper mold 7 will move on the guide shaft 6, so that the cutter shaft 6 guides and limits the movement of the upper mold 7, enabling it to accurately close and extrude with the lower mold 4. The linear vibrator 13 can control the guide rail 14. The material vibrating plate 11 uses the directional force generated by vibration to arrange disordered materials in an orderly manner and transport them to the designated position. The safety light curtains 3 on both sides of the base plate 1 respectively form the transmitting end and the receiving end. The transmitting end has multiple built-in Infrared LEDs emit infrared beams sequentially at a certain frequency. The receiver has multiple built-in photoelectric sensors to receive the beams emitted by the transmitter, forming a dense "infrared protective net". When the equipment is operating normally and the infrared beams emitted by the transmitter are not blocked, the receiver can continuously receive the complete beams and output an "unobstructed" signal to the equipment control system. The equipment continues to operate normally. If an object enters the range of the infrared protective net, it will block part or all of the infrared beams. At this time, the receiver will immediately output an "obstruction alarm" signal to the control system because it cannot receive the complete beams. The control system will respond quickly and trigger cylinder 9 to stop urgently, avoiding safety accidents such as pinching or crushing injuries caused by contact between the human body and moving parts.

[0018] Working principle: In use, the material vibrating plate 11 is first started through the control box 10. The material vibrating plate 11 vibrates the riveting material onto the guide rail 14 until the riveting material fills the guide rail 14. The vibrating plate sensor 12 senses that the material vibrating plate 11 stops vibrating. After the riveting material flows into the designated position, the substrate to be riveted is placed into the lower mold 4 and the riveting material is inserted. Then, the control switches 2 at both ends of the base plate 1 are pressed to start the cylinder 9. The cylinder 9 drives the mounting plate 15 to move downward, and the mounting plate 15 drives the upper mold 7 to descend. The upper mold 7 contacts the lower mold 4 to rivet the substrate and the riveting material. After riveting is completed, the upper mold 7 rises, and the product can be taken out. The safety light curtains 3 installed on both sides of the base plate 1 can prevent hands from being pressed or pinched. When the cylinder 9 drives the upper mold 7 to press down, if a hand is inserted, the safety light curtain 3 will sense it and immediately stop the cylinder 9 to prevent the upper mold 7 and lower mold 4 from pinching the worker's hand, thus playing a safety protection role.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
