Description

Technical Field

[0001] The present invention relates to the technical field of automatic equipment, in particular to an automatic feeding device. Background Art

[0002] At present, the devices used for automatic feeding in the fields of electronics, hardware, etc. are generally implemented by vibrating plates. The vibrating plate makes the hopper vibrate in the vertical direction through the pulse electromagnet under the vibrating plate hopper, and the inclined spring sheet drives the hopper to do torsional vibration around its vertical axis. The parts in the hopper rise along the spiral track due to this vibration. During the rising process, they pass through a series of track screening or posture changes, and the parts can automatically enter the assembly or processing position in a unified state according to the requirements of assembly or processing.

[0003] However, in the process of transforming the existing manual production line of explosion-proof contacts into a semi-automatic production line, the original design of the material discharge direction, the size of the machine space, the center distance between the material channels and other dimensions have been determined. Without changing the layout of the machine, it is impossible to place the vibration plate. In addition, the center of gravity of the contact is at the high cap rod, while the discharge direction of the existing vibration plate is that the contact cap is facing down and the rod is facing up, and the center of gravity is located at the top. Therefore, the traditional vibration plate screening has a low screening survival rate due to the unstable center of gravity, and cannot meet the discharge efficiency of the customer's machine. Summary of the invention

[0004] The invention aims to provide an automatic feeding device which occupies a small space.

[0005] The specific plan is as follows:

[0006] An automatic feeding device comprises a base, a linear vibrator mounted on the base and a material tray mounted on the linear vibrator; the material tray is provided with an ascending material channel and a linear output material channel, the ascending material channel has a bottom end located at a low position and a top end located at a high position, the output material channel is arranged horizontally, one end of the length direction of the output material channel is a feed end, and the other end is a discharge end, the ascending material channel and the output material channel are arranged side by side, and the top end of the ascending material channel is connected to the feed end of the output material channel through an arc channel, the linear vibrator drives the material tray mounted thereon to vibrate back and forth along the length direction of the output material channel, and then the materials stored in the ascending material channel are discharged from the output material channel in sequence.

[0007] Furthermore, the linear vibrator includes two linear vibrators arranged side by side, and the two linear vibrators act on the material tray together.

[0008] Furthermore, a screening channel is provided on the feed end of the output channel, the screening channel has a notch portion, and the material tray has a return channel connecting the notch portion and the bottom of the ascending channel, the screening channel can screen materials whose shapes do not meet the requirements, so that the materials whose shapes do not meet the requirements fall from the notch portion into the return channel.

[0009] Furthermore, the return channel is arranged obliquely, with one end thereof communicating with the notch portion being at a high position, and the other end thereof communicating with the bottom of the ascending channel being at a low position.

[0010] Furthermore, the screening channel is a channel for screening contacts, and the contacts have a disc-shaped cap portion and a columnar rod portion.

[0011] Furthermore, the screening channel includes a first screening channel, a second screening channel, a third screening channel and a fourth screening channel which are arranged in sequence from the feed end to the discharge end of the output channel, the first screening channel is a first arc-shaped channel arranged to match the shape of the contact cap; the second screening channel is a groove which is larger than the outer diameter of the contact rod and smaller than the outer diameter of the contact cap; the third screening channel is a second arc-shaped channel which is lower than the end face of the second screening channel; the fourth screening channel is a channel which is lower than the third screening channel.

[0012] Furthermore, a first notch portion is provided at the end of the first screening channel and is located next to the first screening channel, and the first notch portion is located directly above the return channel.

[0021] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides an automatic feeding device, including a base 1 , a linear vibrator 2 mounted on the base 1 , and a material tray 3 mounted on the linear vibrator 2 .

[0024] Among them, the material tray 3 is provided with an ascending material channel 31 and a linear output material channel 32, the ascending material channel 31 has a bottom end located at a low position and a top end located at a high position, the output material channel 32 is arranged horizontally, one end of the length direction is the feed end, and the other end is the discharge end, the ascending material channel 31 and the output material channel 32 are arranged side by side, and the top end of the ascending material channel 31 is connected to the feed end of the output material channel 32 through an arc channel 33, the linear vibrator 2 drives the material tray 3 installed thereon to reciprocate along the length direction of the output material channel 32, and then the material stored in the ascending material channel 31 is discharged from the output material channel 32 in sequence.

[0025] Since the automatic feeding device provided in this embodiment adopts a smaller linear vibrator to form the output power, replacing the function of the vibration plate's precision body spiral feeding, the maximum external dimensions can be reduced, so that it can be installed in a smaller space, and thus can be used in machines that transform manual contact production lines into semi-automatic production lines.

[0026] In this embodiment, the linear vibrator 2 includes two linear vibrators 21 arranged side by side, and the two linear vibrators 21 act on the material tray 3 together, so that the linear vibrator 2 can generate a greater force on the material tray 3.

[0027] In this embodiment, a screening channel 321 is provided on the feed end of the output channel 32, and the screening channel 321 has a notch portion 320, and the material tray 3 has a return channel 34 connecting the notch portion 320 and the bottom of the ascending channel 31. The screening channel 321 can screen materials that do not meet the requirements in shape, and make the materials that do not meet the requirements in shape fall from the notch portion 320 into the return channel 34. Since the return channel 34 is inclined, one end thereof connected with the notch portion 320 is in a high position, and the other end thereof connected with the bottom of the ascending channel 31 is in a low position. Therefore, the material falling into the return channel 34 will re-enter the ascending channel 31 for screening due to gravity, thereby solving the problem that material return and screening cannot be arranged.

[0028] In this embodiment, the screening channel 321 is a channel for screening the contacts 4. Figure 5 The contact 4 has a rivet-like structure, which includes a disc-shaped cap 41 and a columnar rod 42. In this embodiment, the cap of the contact has a diameter of 3 mm and a thickness of 0.7 mm, the rod has a diameter of 1.5 mm and a height of 2.7 mm. Therefore, the center of gravity of the material is roughly at the connection between the cap and the rod. The discharge direction required by the client is that the cap faces downward, the rod faces upward, and the center of gravity is at the bottom.

[0029] Therefore, the screening channel 321 in this embodiment includes a first screening channel 3211, a second screening channel 3212, a third screening channel 3213 and a fourth screening channel 3214 arranged in sequence from the feed end to the discharge end of the output channel 32, wherein the first screening channel 3211 is a first arc-shaped channel arranged to match the shape of the cap portion 41 of the contact 4, and a first notch portion 3201 located beside the first arc-shaped channel is arranged at the end of the first screening channel 3211. When the shape is different from Figure 6 When the contacts in shape a pass through the first notch portion 3201, due to the offset of the center of gravity of the contacts, most of the contacts that do not conform to shape a will fall from the first notch portion 3201 into the return channel 34 and return to the ascending channel 31 for re-screening.

[0030] The second screening channel 3212 is a groove larger than the outer diameter of the rod and smaller than the outer diameter of the cap. The contact transported from the first screening channel 3211 to the second screening channel 3212 will have its rod drop into the groove of the second screening channel 3212 due to gravity, thereby converting the shape of the contact into Figure 6 The b form in .

[0031] The third screening channel 3213 is a second arc-shaped channel lower than the end surface of the second screening channel 3212. The shape of the second arc-shaped channel is also matched with the shape of the cap 41 of the contact 4. Since the third screening channel 3213 is lower than the second screening channel 3212, when the contact is transported from the second screening channel 3212 to the third screening channel 3213, the cap 41 of the contact is set in advance during the falling process, thereby converting into Figure 6 The c form in .

[0032] The fourth screening channel 3214 is a channel lower than the third screening channel 3213. Since the fourth screening channel 3214 is lower than the third screening channel 3213, when the contact is transported from the third screening channel 3213 to the fourth screening channel 3214, the center of gravity of the contact makes the cap 41 face downward and the rod face upward during the falling process, thereby converting into Figure 6 d form in the above figure, and then sequentially discharged from the discharge end of the discharge channel 32.

[0033] In this embodiment, a second notch portion 3202 is further provided on the side of the fourth screening channel 3214, so that the contacts that do not conform to the d shape in the fourth screening channel 3214 will fall from the second notch portion 3202 into the return channel 34 due to the action of gravity, and return to the rising channel 31 for re-screening, so as to ensure that the contacts finally output from the discharge end of the output channel 32 are all d-shaped contacts, thereby ensuring the screening success rate of the automatic feeding device.

[0034] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
