Description

Technical Field

[0001] The present invention relates to a PIN processing device, and more particularly to a feeding device for a PIN folding machine and a PIN folding machine. Background Art

[0002] PIN is a metal substance used to complete the transmission of electrical signals. PIN is widely used in the fields of military, aerospace, machining, metallurgy, oil drilling, mining tools, electronic communication, etc. With the continuous development and progress of science and technology, especially electronic technology, the market demand is increasing day by day, and the demand for PIN is also rising. In this context, how to improve the processing efficiency of PIN has always been a research hotspot for technicians.

[0003] In the prior art, although the PIN bending work is simple and most of it is done manually, due to the strong demand for PIN folding, some manufacturers have begun to try to manufacture efficient PIN folding machines. To achieve this goal, two processes of feeding and PIN folding need to be completed. Among them, the feeding process is to orderly arrange and output the disorderly stacked PINs, and whether automatic and efficient feeding can be achieved is the key basis for the efficient PIN folding of the PIN folding machine. However, due to the characteristics of a large number of PINs, a relatively small shape of the female PIN body, and fine PIN needles, manual orderly arrangement has problems such as high labor intensity, low efficiency, and easy errors. Therefore, in this technical field, there is an urgent need for a feeding device with a simple configuration, low production cost, and high feeding efficiency. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention urgently needs a feeding device with a simple structure, flexible configuration, high feeding efficiency, and low cost.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows:

[0006] On the one hand, the present invention discloses a feeding device for a PIN folding machine, including: a frame body, a feeding driving unit and a feeding mechanism. The frame body is arranged at the bottom and is used to carry the feeding mechanism and the feeding driving unit; the feeding driving unit is fixedly connected to the frame body and provides driving force for the feeding mechanism; the feeding mechanism is arranged on the top of the frame body and is connected to the feeding driving unit, and under the drive of the feeding driving unit, arranges disordered PINs into PINs with the same direction and outputs them; the PIN includes a female PIN body and a PIN needle connected to the female PIN body; the feeding mechanism includes a feeding part, a feeding channel and a material returning part. The feeding part is in a barrel shape, and the bottom of the outer side is connected to the feeding driving unit; the feeding channel extends from the inner side to the outer side of the feeding part and is spiral; the feeding channel includes a feeding end and a discharging end. The feeding end is arranged at the inner bottom of the feeding part, and the discharging end is arranged at the outer side of the feeding part; the material returning part is sleeved around the feeding part, and the bottom of the material returning part communicates with the bottom of the feeding part.

[0007] The beneficial effects of adopting the above technical solution are as follows: fully considering the problems in the prior art that the processing of PINs has manual PIN picking and feeding, low efficiency and high labor costs, the feeding mechanism and the feeding driving unit are organically combined for automatic feeding. Among them, a spiral feeding channel is introduced into the feeding mechanism, so that the PINs can be arranged as required during the spiral conveying process of the feeding channel, and finally PINs with orderly arrangement and the same PIN needle direction are obtained. The whole process is automatically completed by the feeding device, saving manual allocation. In addition, the equipment itself has a simple configuration, which can effectively reduce costs while improving production efficiency. Therefore, the feeding device of the present technical solution has both practicability and economy.

[0008] As a further improvement of the present invention, the bottom of the feeding part is in a convex shape with a high center and low surroundings, and the feeding end is arranged at the bottom edge of the feeding part.

[0009] The beneficial effects of adopting the above technical solution are as follows: the feeding end is arranged at the lowest position of the feeding part. When there is only a small amount of remaining PINs, they can still successfully enter the feeding end, which can effectively improve the success rate of the feeding end receiving PINs.

[0010] As a further improvement of the present invention, the feeding driving single piece is an eccentric motor, which is used to provide vibration driving force for the feeding mechanism.

[0011] The beneficial effects of adopting the above technical solution are as follows: the setting of the eccentric motor provides vibration driving force for the feeding mechanism, so that the feeding mechanism drives the PINs to gradually move from the lower end of the spiral feeding channel under the drive of regular vibration, and the operation is stable.

[0012] As a further improvement of the present invention, the feeding channel also includes a lifting section, a sorting section and a screening section. The lifting section starts from the feed end and spirally rises on the inner side of the feeding section to the top of the feeding section; the screening section hovers on the outer side of the feeding section; the sorting section is located at the top of the feeding section, for receiving the PINs of the lifting section, and transporting the PINs to the screening section after orderly arranging them in the same direction of the PIN pins.

[0013] The beneficial effect of adopting the above technical solution is that the lifting section and the screening section are respectively arranged on the inner side and the outer side of the feeding part, and are connected by the material sorting section. The setting of the material sorting section helps to realize the orderly arrangement of PINs in the process of transferring PINs from the inner side to the outer side of the feeding part. Compared with the orderly arrangement in the lifting section or the screening section, the orderly arrangement through the material sorting section is simpler and has a higher success rate.

[0014] As a further improvement of the present invention, the upper surface of the lifting section forms an angle with the inner side surface of the feeding portion, the angle is less than 90 degrees, and the upper surface is in direct contact with the PIN.

[0015] The beneficial effect of adopting the above technical solution is: the setting of an angle less than 90 degrees provides a channel for the vibration rise of the PIN, which prompts the PIN to gradually rise along the intersection line formed by the inner side surface of the lifting section and the feeding part during the rising process, effectively preventing the PIN from falling during the conveying process and improving the conveying efficiency of the PIN.

[0016] As a further improvement of the present invention, the female PIN body has different outer diameters, and the maximum outer diameter of the female PIN body is located at the end of the female PIN body facing the PIN pin or the end away from the PIN pin; the material sorting section includes a material receiving connection plate, a material sorting baffle plate and a material screening connection plate, one end of the material receiving connection plate is connected to the material lifting section, and the other end thereof is suspended; one end of the material screening connection plate is located below the suspended end of the material receiving connection plate and is suspended, and the other end thereof is connected to the material screening section; the material sorting baffle plate is fixed above the material screening connection plate along the rotation direction of the material screening connection plate, and the inner side spacing between the material sorting baffle plate and the material screening connection plate is smaller than the maximum outer diameter of the female PIN body, and larger than the outer diameter of the rest of the female PIN body.

[0017] The beneficial effect of adopting the above technical solution is that when the female PIN body has different outer diameters,

[0018] As a further improvement of the present invention, the screening section includes a spiral bottom plate, the spiral bottom plate has an outer ring and an inner ring, the edge of the outer ring of the spiral bottom plate is higher than the edge of the inner ring at a corresponding position, the edge of the outer ring is far away from the feeding part, and the edge of the inner ring is close to the feeding part, and the edge of the inner ring of the spiral bottom plate is provided with a stop baffle.

[0019] The beneficial effects of adopting the above technical solution are as follows: The edge of the outer circle of the spiral bottom plate is higher than the edge of the inner circle. Coupled with the setting of the anti-falling baffle, it prompts the PIN to always be in an inclined state during the conveying process in the material screening section. This inclined state is not only beneficial to keeping the PIN advancing during vibration but also can prevent the PIN from falling during the advancing vibration process.

[0020] As a further improvement of the present invention, leakage holes are provided on the spiral bottom plate, and the leakage holes are used to screen out the PINs whose arrangement directions are different from the predetermined arrangement direction.

[0021] The beneficial effects of adopting the above technical solution are as follows: The setting of the leakage holes helps to screen out individual PINs with opposite arrangement directions during the advancing process of the PINs, thereby maintaining the purity of the PINs arranged in an orderly manner in a specified direction and improving the efficiency of the orderly arrangement of the PINs.

[0022] As a further improvement of the present invention, the material screening section further includes a guiding bar, the guiding bar is laid along the extending direction of the spiral bottom plate, and the vertical distance between the guiding bar and the edge of the outer circle of the spiral bottom plate is equal; along the output direction of the PIN, the height difference between the edge of the outer circle and the edge of the inner circle of the spiral bottom plate gradually increases until the spiral bottom plate is arranged in a vertical direction.

[0023] The beneficial effects of adopting the above technical solution are as follows: The setting of the guiding bar, in cooperation with the edge of the outer circle of the spiral bottom plate, constructs a guiding channel for the PINs and provides strong support and guarantee for the gradual change of the inclination angle of the PINs.

[0024] On the other hand, the present invention also discloses a PIN folding machine, and the PIN folding machine includes the feeding device for the PIN folding machine according to any one of the above solutions.

[0025] The beneficial effects of adopting the above technical solution are as follows: The PIN folding machines including the feeding devices in any one of the above technical solutions can automatically convey the PINs with the same PIN needle orientation for the PIN folding machine, and can effectively solve the technical problems of manual PIN picking and feeding, low efficiency, and high labor cost.

[0036] The beneficial effects of adopting the above technical solution are as follows: fully considering the problems in the prior art that there are manual PIN picking and feeding in PIN processing, low efficiency and high labor cost, the feeding mechanism and the feeding driving unit are organically combined for automatic feeding. Among them, a spiral feeding channel is introduced in the feeding mechanism, so that the PIN can be arranged as needed during the spiral transportation process of the feeding channel, and finally the PIN with orderly arrangement and the same PIN needle direction is obtained. The whole process is automatically completed by the feeding device, saving manual configuration. Coupled with the simple configuration of the equipment itself, while improving production efficiency, the cost can be effectively reduced. Therefore, the feeding device of this technical solution has both practicability and economy.

[0042] The beneficial effects of adopting the above technical solution are as follows: The lifting section and the screening section are respectively arranged inside and outside the feeding part, and are connected through the sorting section. The setting of the sorting section helps to realize the orderly arrangement of the PIN during the transfer process of conveying the PIN from the inside of the feeding part to the outside.
