Description

Technical Field

[0001] This utility model belongs to the technical field of industrial automation feeding equipment, specifically relating to a stable feeding device suitable for rubber ball parts. Background Technology

[0002] In industrial production, rubber ball parts play a vital role in various mechanical equipment due to their excellent elasticity and sealing properties. However, due to the inherent physical properties of rubber, they face a series of problems caused by static electricity during automated feeding, severely affecting feeding stability and efficiency. Current technologies for feeding rubber ball parts mainly rely on vibratory feeders in conjunction with pick-and-place mechanisms, but these methods suffer from the following prominent issues: First, the continuous vibration within the vibratory feeder causes frequent friction between the parts and between the parts and the inner wall of the feeder, easily generating a large amount of static electricity. When these statically charged rubber balls enter the conveyor track after being screened by the vibratory feeder, they adhere to the inner wall of the track due to electrostatic adsorption, causing jamming or even blockages during transport, severely affecting the continuity of feeding. Simultaneously, during the picking process, static electricity causes the rubber balls to attract and stick together. When using a pick-and-place mechanism, it is difficult to ensure accurate picking of each ball individually, often resulting in multiple balls being picked up at once or failure to pick up any balls at all, significantly reducing picking efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stable feeding device for rubber ball parts, which solves the problems of easy jamming and difficulty in ensuring that the picking and placing mechanism can accurately pick up each rubber ball part when using a vibratory feeder.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stable feeding device for rubber ball parts, including a vibratory plate, an anti-static air pipe, an ion fan, and a feeding box;

[0005] One end of the antistatic air pipe is connected to the feeding port on the vibrating plate, and a bypass air pipe is inclinedly connected to the feeding port. The other end of the antistatic air pipe is connected to the feeding box and communicates with the feeding track inside the feeding box.

[0006] The feeding box is provided with an ion air duct and a discharge port that are respectively connected to the end of the antistatic air pipe in the feeding track away from the end of the antistatic air pipe.

[0007] The discharge port faces upwards, and the ion air duct and the bypass air pipe are connected to the ion air outlet of the ion blower through pipelines. The inner diameter of the ion air duct and the bypass air pipe is smaller than the diameter of the rubber ball.

[0008] Optionally, a sensor electrically connected to the ion fan is also included, which is used to monitor whether a rubber ball is present at the end of the feeding track.

[0009] Optionally, the port of the ion channel connected to the end of the feeding track is located directly below the discharge port, and the rubber ball can be attached to the edge of the port of the ion channel connected to the end of the feeding track.

[0010] Optionally, the antistatic air pipe can be connected to the feeding track through a first air pipe interface provided on the feeding box, and the rubber ball inside the antistatic air pipe can flow into the feeding track through the first air pipe interface;

[0011] The pipe connected to the ion outlet can be connected to the ion duct through the second air pipe interface provided on the feed box.

[0012] Optionally, the feeding box includes a connector plate and a first housing detachably connected to the connector plate. A second housing is detachably connected to the first housing. The feeding track is formed between the first housing and the second housing, and the first housing and / or the second housing is transparent.

[0013] Optionally, the diameter of the discharge port is adapted to the size of the rubber ball, and the discharge port can only accommodate a single rubber ball.

[0014] Optionally, the feeding box is slidably connected to the profile bracket in the vertical direction, and a multi-directional adjustment bracket for mounting the sensor is slidably connected to the profile bracket in the vertical direction.

[0015] The feeding box and the multi-directional adjustment bracket can both be fixed to the profile bracket by the profile bolt assembly.

[0016] Optionally, the multi-directional adjustment bracket includes a mounting plate that can be slidably connected to the profile bracket. The mounting plate has a shaft hole for mounting the optical axis in the vertical direction, and the top end of the optical axis is provided with an angle adjustment plate for mounting the sensor.

[0017] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: the rubber balls in the vibratory feeder can enter the anti-static air pipe sequentially through the feeding port, and the ion air generated by the ion blower can be directed to the ion air duct and the bypass air pipe through pipelines, so that some of the ion air blown out through the ion air duct can directly blow onto the rubber balls placed at the end of the feeding track, quickly neutralizing the static charge on their surface. The ion air through the bypass path can enter the feeding track along the anti-static air pipe, continuously eliminating the static charge on the surface of the rubber balls in this section, ensuring that the rubber balls in the anti-static air pipe and the feeding track can flow smoothly by gravity, while also being propelled by airflow to avoid conveying jams, and the rubber balls will not attract each other, ensuring that the picking and unloading mechanism can accurately pick up individual rubber balls from the discharge port.

[0025] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1

[0026] like Figures 1-4 As shown, a stable feeding device for rubber ball parts includes a vibratory feeder 1, an anti-static air pipe 2, an ion fan 3, and a feeding box 4. The anti-static air pipe 2 is a tubular conveying component with anti-static function. It can prevent the accumulation of static electricity in the flowing medium inside the pipe during the conveying process through its own conductivity or anti-static properties, or prevent external static electricity from drying out the medium inside the pipe. In this technical solution, one end of the anti-static air pipe 2 is connected to the feeding port 101 on the vibratory feeder 1. A bypass air pipe 102 is inclinedly connected to the feeding port 101. The other end of the anti-static air pipe 2 is connected to the feeding box 4 and communicates with the feeding track 404 inside the feeding box 4. At the same time, the feeding box 4 is provided with an ion channel 405 and a discharge port 406, which are respectively connected to the end of the anti-static air pipe 2 in the feeding track 404.

[0027] The outlet 406 faces upwards, and its diameter is matched to the size of the rubber ball. Only a single rubber ball can pass through the outlet 406. The ion duct 405 and bypass air pipe 102 are connected to the ion outlet of the ion blower 3 via pipelines. It should be noted that the pipeline consists of a flow control valve, a tee connector, and multiple air pipes (not fully shown in the figure) to divert the ion air generated by the ion blower 3. The flow rate of the ion air entering the bypass air pipe 102 and ion duct 405 can be adjusted according to actual needs, thus meeting different practical requirements. Simultaneously, the inner diameter of the ion duct 405 and bypass air pipe 102 is smaller than the diameter of the rubber ball to prevent the rubber ball from blocking the ion duct 405 and bypass air pipe 102 in the reverse direction.

[0028] Specifically, in actual use, the ionizing air generated by the ionizing fan 3 can directly enter the feeding track 404 through the pipeline, and can also enter the feeding track 404 through the bypass air pipe 102 and the anti-static air pipe 2. The ionizing air blown out through the ionizing air duct 405 can directly blow on the rubber balls placed at the end of the feeding track 404. Under the action of the ionizing air, the static charge on the surface of the rubber balls can be quickly attracted and neutralized. Therefore, when the material is picked up and put away by the existing picking and putting mechanism, the rubber balls placed at the end of the feeding track 404 will not be attracted to other rubber balls, thus ensuring that the picking and putting mechanism can accurately pick up the rubber balls one by one. The ionizing air entering the feeding track 404 through the bypass air pipe 102 and the anti-static air pipe 2 can continuously eliminate the static charge on the surface of the rubber balls placed in the anti-static air pipe 2 and the feeding track 404, so that the rubber balls flowing out of the feeding port 101 on the vibrating plate 1 can flow smoothly into the feeding track 404 on the feeding box 4 under the action of their own gravity. Meanwhile, the ionizing air introduced from the bypass air pipe 102 can push the rubber balls that have entered the antistatic air pipe 2 to flow into the feed track 404 in the feed box 4, thereby effectively preventing the rubber balls from getting stuck during the conveying process.

[0029] Meanwhile, compared with the existing technology that uses a track to transport rubber balls along a fixed path, this technical solution uses an anti-static air pipe 2 to transport rubber balls. This not only provides an air duct for the ion wind that can eliminate the static charge on the surface of the rubber balls, but also allows the anti-static air pipe 2 to be bent at a certain angle according to the site environment, thereby meeting the needs of flexible site layout.

[0030] It should be noted that, as mentioned above... Figure 1 The vibratory feeder 1 shown is an automated device that uses the principle of vibration to automatically sort and directionally convey materials, which is a type of existing technology.

[0031] Furthermore, such as Figure 1 , Figure 2As shown, the stable feeding device for rubber ball parts also includes a sensor 5 electrically connected to the ion fan 3. This sensor 5 monitors whether a rubber ball exists at the end of the feeding track 404. The sensor 5 can preferably be a photoelectric sensor from the prior art. When the sensor 5 detects a rubber ball at the end of the feeding track 404, it feeds back the signal to the controller, actuator, and host computer. After processing the signal, the controller, actuator, and host computer can control the ion fan 3 to start. When the sensor 5 does not detect a rubber ball, the controller, actuator, and host computer can control the ion fan 3 to shut down. This allows the ion fan 3 to "work on demand," meaning it can be in a dormant or low-power state during non-feeding phases (when there are no balls at the end of the feeding track 404), significantly reducing its operating time and energy consumption.

[0032] In this embodiment, the port of the ion channel 405 connected to the end of the feeding track 404 is located directly below the discharge port 406, and the rubber ball can overlap the edge of the port of the ion channel 405 connected to the end of the feeding track 404. That is, the edge of the port of the ion channel 405 connected to the end of the feeding track 404 can serve as a positioning reference when the rubber ball flows to the end of the feeding track 404, thereby increasing the accuracy of the picking and unloading mechanism in picking up the rubber ball one by one. However, it should be noted that the ion wind ejected from the ion channel 405 has a relatively low wind speed (which can be adjusted by the flow control valve in the pipeline), and will not blow the rubber ball placed at the end of the feeding track 404 away. It will only cause the rubber ball placed at the end of the feeding track 404 to float and deflect within a small range, thereby effectively increasing the contact area between the ion wind and the rubber ball, and thus increasing the effect of the rubber ball in eliminating static charge.

[0033] Furthermore, such as Figure 2 , Figure 3 , Figure 4 As shown, the antistatic air pipe 2 can be connected to the feeding track 404 through the first air pipe interface 6 provided on the feeding box 4, and the rubber ball inside the antistatic air pipe 2 can flow into the feeding track 404 through the first air pipe interface 6. The pipe connected to the ion outlet can be connected to the ion air duct 405 through the second air pipe interface 7 provided on the feeding box 4. The first air pipe interface 6 and the second air pipe interface 7 are quick-connect interfaces, which can be quickly connected to the antistatic air pipe 2 or the pipe, and will not easily fall off.

[0034] Furthermore, such as Figure 3As shown, the feeding box 4 includes a connector plate 401 and a first housing 402 detachably connected to the connector plate 401. One end of the first air pipe interface 6 can be threaded onto the connector plate 401 and can be sealed and connected to the feeding track. A second housing 403 is detachably connected to the first housing 402, and a feeding track 404 is formed between the first housing 402 and the second housing 403. One end of the second air pipe interface 7 can be threaded onto the first housing 402 or the second housing 403, and the second air pipe interface threaded onto the first housing 402 can be sealed and connected to the ion air duct 405 provided on the first housing 402, or the second air pipe interface threaded onto the second housing 403 can be sealed and connected to the ion air duct 405 provided on the second housing 403. The first housing 402 and / or the second housing 403 are transparent. Bolts (not shown in the figure) that can be threaded onto the connector plate 401 and connected to the first housing 402 can be threaded onto it, thereby connecting and fixing the connector plate 401 to the first housing 402. Similarly, bolts (not shown in the figure) that can be threaded onto the second housing 403 and connected to the first housing 402 can be threaded onto it, thereby connecting and fixing the first housing 402 and the second housing 403. At the same time, the operator can directly observe the situation inside the feeding track 404 through the transparent first housing 402 or the second housing 403. And if the feeding track 404 becomes blocked due to special circumstances, the feeding track 404 can be cleared by quickly disassembling the first housing 402 or the second housing 403. Example 2

[0035] like Figures 2-4 As shown, based on Embodiment 1, the material feeding box 4 is slidably connected to the profile bracket 8 in the vertical direction, and a multi-directional adjustment bracket for mounting the sensor 5 is slidably connected to the profile bracket 8 in the vertical direction. Both the material feeding box 4 and the multi-directional adjustment bracket can be fixed to the profile bracket 8 by profile bolt assembly, so that the positions of the material feeding box 4 and the sensor 5 mounted on the profile bracket 8 can be adjusted as needed.

[0036] Furthermore, such as Figure 2As shown, the multi-directional adjustment bracket includes a mounting plate 9 that can be slidably connected to the profile bracket 8, meaning the mounting plate 9 can be fixedly mounted on the profile bracket 8 via a profile bolt assembly. Since the mounting plate 9 has a shaft hole for mounting the optical axis 10 vertically, the shaft hole can clamp and fix the optical axis 10 by contracting its opening, as can be seen in the prior art where an optical axis fixing block fixes the optical axis 10. Before the shaft hole is tightened, the optical axis 10 can rotate and move up and down along the shaft hole. Simultaneously, an angle adjustment plate 11 for mounting the sensor 5 is provided at the top of the optical axis 10. The angle adjustment plate 11 can be fixed to the top of the optical axis 10 with bolts. Two bolts are threaded onto the angle adjustment plate 11, each capable of being threadedly connected to the sensor 5. When these two bolts are not fully tightened, the sensor 5 can rotate around one of the bolts, while the other bolt can slide along the side wall of the arc-shaped hole on the angle adjustment plate 11. When these two bolts are tightened, the sensor 5 can also be fixed to the angle adjustment plate 11. The specific structure of the angle adjustment plate 11 is as follows... Figure 2 As shown, and can be referenced in the prior art for assembling aluminum profiles, an "angle adjustment plate". It should be noted that the rotation axis of sensor 5 is perpendicular to the central axis of optical axis 10, so the position and angle of sensor 5 can be adjusted in multiple directions as needed.

[0037] Working Principle: Rubber balls in the vibratory feeder 1 enter the anti-static air duct 2 sequentially through the feeding port 101. Simultaneously, the ionizing air generated by the ion fan 3 acts on the rubber balls throughout the entire conveying process via a dual path. One portion of the ionizing air blows directly onto the rubber balls placed at the end of the feeding track 404 via the ion duct 405, quickly neutralizing their surface static electricity and preventing them from adhering to other rubber balls during handling. The other portion of the ionizing air enters the anti-static air duct 2 and the feeding track 404 via the bypass air pipe 102, continuously eliminating static charge on the surface of the rubber balls during conveying. This ensures the rubber balls flow smoothly under gravity while also preventing jamming through airflow, ultimately ensuring that the picking and unloading mechanism can accurately remove individual rubber balls from the discharge port 406, achieving stable feeding.

[0038] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
