Description

Technical Field

[0001] The present invention relates to an air intake cover assembly system, and more particularly to an automatic discharging machine for air intake cover assembly. Background Art

[0002] With the continuous development of industrial automation, the degree of automation is getting higher and higher, and more and more labor is liberated. Industrial automation technology is a comprehensive high-tech that uses control theory, instrumentation, computers, and other information technologies to achieve detection, control, optimization, scheduling, management, and decision-making in industrial production processes, aiming to increase production, improve quality, reduce consumption, ensure safety, etc. It includes three major parts: industrial automation software, hardware, and systems. As one of the most important technologies in the modern manufacturing field in the 21st century, industrial automation technology mainly solves the problems of production efficiency and consistency. Whether it is a high-speed mass manufacturing enterprise or an enterprise pursuing flexibility, flexibility, and customization, it must rely on the application of automation technology. It plays an obvious role in improving the enterprise production process:

[0003] (1) Improve the safety of the production process;

[0004] (2) Improve production efficiency;

[0005] (3) Improve product quality;

[0006] (4) Reduce the consumption of raw materials and energy in the production process.

[0007] The air quality sensor is one of the commonly used sensors nowadays, which can be used to monitor the concentration of pollutants in the air and is an important part of air purifiers and fresh air systems. The production volume of the air intake cover set on the air quality sensor is also very large. However, the existing feeding method usually relies on manual discharging one by one, and the feeding efficiency of such a feeding method is very low, which is difficult to meet the requirements of automated production, thus reducing the production efficiency. To improve the overall feeding efficiency, multiple people need to discharge materials simultaneously, which will not only increase the labor cost but also raise the production cost.

[0008] The vibrating bowl is an auxiliary feeding device for automatic assembly or automatic processing machinery. It can arrange various products in an orderly manner, cooperate with automatic assembly equipment to assemble various parts of the product into a complete product, or cooperate with automatic processing machinery to complete the processing of workpieces. Summary of the Invention

[0009] Existing vibrating bowls are usually used for automatic discharging of objects with regular shapes. It is difficult to achieve good arrangement for objects with irregular shapes such as the air intake cover of the air quality sensor, thus unable to meet the requirements of automatic arrangement of the air intake cover.

[0010] The object of the present invention is to provide an automatic discharging machine for intake cover assembly to solve at least one of the above problems, which realizes the automatic arrangement of intake covers and can automatically send them to the next process for subsequent processing and assembly.

[0011] The object of the present invention is achieved by the following technical solutions:

[0012] An automatic discharging machine for intake cover assembly includes a vibrating bowl, a feeding track and a first blowing device;

[0013] The feeding track is wound around the outside of the vibrating bowl, receives intake covers from the vibrating bowl at one end, and sends the intake covers out of the automatic discharging machine for intake cover assembly at the other end; the width of the feeding track is different, so that the intake covers with incorrect orientations fall off.

[0014] The first blowing device is arranged on the side of the feeding track, and its blowing direction is perpendicular to the track to blow off the intake covers with incorrect orientations.

[0015] Preferably, the feeding track includes a first screening section, a second screening section, a third screening section and a fourth screening section connected in sequence, and the widths of the first screening section, the second screening section and the third screening section decrease in sequence; the ratio of the width of the first screening section and the fourth screening section to the diameter of the intake cover is 1.4 - 1.6:1, the ratio of the width of the second screening section to the diameter of the intake cover is 1.15 - 1.25:1, and the ratio of the width of the third screening section to the diameter of the intake cover is 0.65 - 0.8:1. The intake covers with incorrect orientations will fall off the feeding track at the third screening section which is smaller than its diameter.

[0016] Preferably, the feeding track is continuously inclined from one end (the feeding end receiving the intake covers from the vibrating bowl) to the other end, and the inclination continuously increases the angle from the feeding end (the angle with the horizontal plane is 0°) to the other end (the angle with the horizontal plane is 60°), which is beneficial for the intake covers with incorrect orientations to fall off the feeding track.

[0017] Preferably, the ratio of the height of the first blowing device (the distance above the track) to the height of the intake cover is 0.8 - 0.9:1. The first blowing device blows off the intake covers with incorrect orientations from the feeding track.

[0018] Preferably, the end part of the feeding track is a slot track, and the slot track is respectively provided with slots for clamping the intake covers on both sides of the track. The height of the slots is the same as the height of the convex blocks arranged on the side of the intake cover. When the intake covers with correct orientations enter the slot track, they are clamped by the slots to prevent them from falling off; the first blowing device is arranged at the head of the slot track to blow off the intake covers with incorrect orientations, while the intake covers with correct orientations will not be blown off because they are clamped by the slots.

[0019] Preferably, a second air blowing device is provided above the end of the card slot track. The blowing direction of the second air blowing device forms an angle of 15-40° with the track extension direction, and is used to assist the air inlet cover reaching the end of the card slot track to continue moving forward and enter the next working section.

[0020] Preferably, a conveyor belt is further provided at the end of the card slot track, which cooperates with the second air blowing device. After the air inlet cover is pushed onto the conveyor belt, it is transported to the next working section by the conveyor belt.

[0021] Preferably, an infrared sensor is further provided at the end of the card slot track, which is used to detect whether the air inlet cover enters the next working section through the sensing area. When the air inlet cover does not pass, the second air blowing device does not blow air; when the air inlet cover passes, the second air blowing device starts to blow air to push the next air inlet cover forward.

[0022] Preferably, a spiral track spiraling upward along the inner wall is provided inside the vibrating disk. Grooves and gullies are provided at the bottom of the spiral track, so that the air inlet cover gradually moves upward along the spiral track as the vibrating disk operates.

[0023] Preferably, a third air blowing device is provided above the end of the spiral track. The blowing direction of the third air blowing device forms an angle of 15-40° with the track extension direction, and is used to assist in blowing the air inlet cover from the end of the spiral track onto the feeding track.

[0024] Preferably, the air inlet cover assembly automatic discharging machine further includes a material sensor, and the material sensor extends to the bottom of the vibrating disk to detect whether there is an air inlet cover inside the vibrating disk.

[0025] Preferably, an inlet allowing the dropped air inlet cover to return to the vibrating disk is provided at the bottom of the vibrating disk. The air inlet cover dropped on the feeding track returns to the inside of the vibrating disk through this inlet and is discharged again.

[0026] Preferably, the first air blowing device, the second air blowing device and the third air blowing device are all air blowing rods.

[0027] The working principle of the present invention is as follows:

[0028] The air inlet covers placed inside the vibrating disk gradually rise along with the spiral track under the operation (vibration) of the vibrating disk. Most of the air inlet covers with incorrect orientations will fall into the vibrating disk during the rising process and are discharged again. After the air inlet cover rises to the end of the spiral track, it continues to move forward along the feeding track as the vibrating disk operates. The width of the feeding track gradually becomes narrower, and a part of the air inlet covers with incorrect orientations will fall here. The remaining air inlet covers move forward to the card slot track. Those with correct orientations will be caught by the card slot track, while those with incorrect orientations will be blown off by the first air blowing device. Under the continuous operation of the vibrating disk, the air inlet covers continue to move forward and enter the next working section.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. On the basis of the vibrating bowl, an additional feeding track and a card slot track with different widths are added, which can effectively remove the intake covers with incorrect orientations in the queue and ensure that the intake covers with correct orientations move forward stably and are sent to the next process section.

[0031] 2. A blowing device is arranged at the end of the feeding track to blow away the intake covers with incorrect orientations. Blowing devices are respectively arranged at the ends of the spiral track and the card slot track to assist in pushing the intake covers to continue moving forward. The blowing device arranged at the end of the spiral track plays a main pushing role when there is not much material inside the vibrating bowl.

[0032] 3. A conveyor belt is arranged at the end of the card slot track to assist in transporting the intake covers, and an infrared sensor is arranged to control the discharging frequency and speed, ensuring the orderly operation of the automatic discharging machine and subsequent process sections.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Embodiment 1

[0041] An automatic discharging machine for assembling an intake cover, as Figures 1-3As shown, it includes a vibrating bowl 1, a feeding track 2, and a first blowing device (not shown in the figure); the feeding track 2 is wound around the outside of the vibrating bowl 1, one end receives the air intake cover from the vibrating bowl 1, and the air intake cover is sent out by the other end to be assembled into an automatic discharging machine; the width of the feeding track 2 is different, so that the air intake covers with incorrect orientations fall off; the first blowing device is arranged on the side of the feeding track 2, and its blowing direction is perpendicular to the track to blow off the air intake covers with incorrect orientations.

[0042] More specifically, in this embodiment:

[0043] Inside the vibrating bowl 1, there is a spiral track 11 spiraling upward along the inner wall. At the bottom of the spiral track 11, various types of grooves and gullies are provided to assist the air intake cover to gradually move upward along the spiral track 11 with the vibration of the vibrating bowl 1. Above the end of the spiral track 11, a third blowing device (not shown in the figure) is provided, and the angle between its blowing direction and the extending direction of the track is about 20°, to assist in blowing the air intake cover onto the feeding track 2. Especially when there is less material inside the vibrating bowl 1, it is difficult to send it onto the feeding track 2 only relying on the vibration of the vibrating bowl 1, and it is necessary to rely on blowing to push it forward. At this time, the blowing becomes the main driving force for its advancement.

[0044] The feeding track 2 can be divided into a first screening section 21, a second screening section 22, a third screening section 23, and a fourth screening section 24 connected in sequence according to the width change, as Figure 4 shown, where the widths of the first screening section 21, the second screening section 22, and the third screening section 23 decrease in sequence. The ratio of the width of the first screening section 21 and the fourth screening section 24 to the diameter of the air intake cover is 1.4:1, the ratio of the width of the second screening section 22 to the diameter of the air intake cover is 1.2:1, and the ratio of the width of the third screening section 23 to the diameter of the air intake cover is 0.7:1. A part of the air intake covers with incorrect orientations will fall off the feeding track 2 at the third screening section 23. Particularly, the feeding track 2 is continuously inclined from the feeding end to the discharging end. The angle between the feeding track 2 and the horizontal plane at the feeding end is about 0°, and the angle between the feeding track 2 and the horizontal plane at the discharging end is about 60°, which is more conducive to the air intake covers with incorrect orientations falling off the feeding track 2.

[0045] The end of the feeding track 2 is a clamping groove track 25. On both sides of the track, there are clamping grooves for clamping the air inlet cover. The height of the clamping groove is the same as the height of the convex block provided on the side of the air inlet cover. Clamping grooves for clamping the air inlet cover are respectively arranged on both sides of the clamping groove track 25. In this way, the air inlet cover with the correct orientation will be clamped by the clamping groove when entering the clamping groove track 25 and will not be knocked off or blown off. The first blowing device is arranged on the side of the head end of the clamping groove track 25, and the ratio of its height (the distance from the track) to the height of the air inlet cover is 0.9:1. In this way, the air flow blown by the first blowing device will be concentrated on the upper part of the air inlet cover, which is beneficial to blowing off the air inlet cover with the wrong orientation, while the air inlet cover with the correct orientation will not be blown off because it is clamped by the clamping groove. At the bottom of the vibrating bowl 1, there is an inlet through which the dropped air inlet cover can return to the vibrating bowl 1. The air inlet cover dropped on the feeding track 2 returns to the inside of the vibrating bowl 1 through this inlet and is discharged again.

[0046] A second blowing device (not shown in the figure) is arranged above the end of the clamping groove track 25. The blowing direction of this blowing device forms an angle of approximately 20° with the extending direction of the track. At the same time, there is a conveyor belt at the very end of the clamping groove track 25. The second blowing device can assist in pushing the air inlet cover onto the conveyor belt and transporting it to the next process section through the conveyor belt; the infrared sensor detects whether the air inlet cover passes through. When it detects that the air inlet cover is in the sensing area, the second blowing device stops blowing and the conveyor belt stops running; when it detects that the air inlet cover leaves the sensing area, the second blowing device starts blowing and the conveyor belt starts operating to convey the next air inlet cover forward.

[0047] The entire automatic discharging machine further includes a material sensor 3 for sensing whether there is still an air inlet cover inside the vibrating bowl 1. The sensing head of the material sensor 3 extends into the vibrating bowl 1 until the bottom of the vibrating bowl 1.

[0048] In this embodiment, the intake cover first gradually rises along the spiral track 11 under the vibration of the vibrating disk 1 and reaches the end of the spiral track 11. During this period, most of the intake covers with incorrect orientations fall from the spiral track 11 and return to the bottom of the vibrating disk 1 for re-feeding. Under the push of the third blowing device and the vibration of the vibrating disk 1, the intake cover enters the feeding track 2 and advances along the feeding track 2. When the intake cover reaches the third screening section 23, since the width of the third screening section 23 is smaller than the diameter of the intake cover and has a certain inclination, some intake covers with incorrect orientations will fall from the feeding track 2 with the vibration of the vibrating disk 1. After passing through the third screening section 23 and the fourth screening section 24, when reaching the card slot track 25, the bumps on both sides of the intake cover with the correct orientation will be caught by the card slots, while the intake covers with incorrect orientations will be blown off by the first blowing device arranged at the head end of the card slot track 25. All the fallen intake covers will be collected around the vibrating disk 1 and returned to the inside of the vibrating disk 1 through the opening at the bottom of the vibrating disk 1 for re-feeding. The intake covers passing through the first blowing device are all intake covers with the correct orientation. When being conveyed to the end of the card slot track 25, they will be pushed forward to the conveyor belt by the second blowing device together. The infrared sensor arranged on the side detects whether the intake cover passes. When it is detected that the intake cover does not pass, it indicates that there may be a pile-up in the front process section. At this time, the second blowing device and the conveyor belt pause. When it is detected that the intake cover passes, the second blowing device and the conveyor belt are restarted to continue conveying the intake cover to the next process section.

[0049] The working principle of the present invention is as follows:

[0050] The intake cover placed inside the vibrating disk 1 gradually rises along the spiral track 11 under the operation (vibration) of the vibrating disk 1. Most of the intake covers with incorrect orientations will fall into the inside of the vibrating disk 1 during the rising process for re-feeding. After the intake cover rises to the end of the spiral track 11, it continues to advance along the feeding track 2 with the operation of the vibrating disk 1. The width of the feeding track 2 gradually becomes narrower, and some intake covers with incorrect orientations will fall at this place. The remaining intake covers advance to the first blowing device, where the remaining intake covers with incorrect orientations will be blown off here, and the intake covers with the correct orientation continue to advance into the card slot track 25 and are caught by the card slots to prevent falling. Under the operation of the vibrating disk 1, the intake cover continues to advance into the next process section.

[0051] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the invention. Those familiar with the technology in this field can obviously make various modifications to these embodiments easily and apply the general principles described herein to other embodiments without creative labor. Therefore, the present invention is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art according to the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
