Description

Technical Field

[0001] This application relates to the field of material feeding technology, and in particular to an automatic feeding device for a vibratory feeder. Background Technology

[0002] Vibratory feeders are widely used in many industrial fields such as electronics manufacturing and component processing as a common automatic feeding or sorting device. They can arrange disordered workpieces or materials in an orderly manner according to certain rules and transport them to the next production stage, greatly improving production efficiency and automation. Currently, there are various automatic vibratory feeder replenishment devices on the market, which to some extent replenish the materials in the vibratory feeder. However, existing automatic vibratory feeder replenishment devices have many shortcomings when dealing with replenishing special materials such as aluminum electrolytic capacitors. The feeding speed of existing replenishment devices is relatively fixed and cannot be adjusted in real time according to the production rhythm and the consumption rate of materials in the vibratory feeder, easily leading to over- or under-feeding, affecting the continuity and stability of production. Furthermore, for materials like aluminum electrolytic capacitors, existing replenishment devices may not be able to guarantee their stable and smooth entry into the vibratory feeder during the replenishment process, easily causing problems such as material jamming, affecting replenishment efficiency and production progress.

[0003] Regarding the aforementioned technologies, there is a drawback that the feeding device cannot guarantee the stable and smooth entry of materials such as capacitors into the vibratory feeder. Utility Model Content

[0004] In order to enable materials such as capacitors to enter the vibratory feeder stably and smoothly, this application provides an automatic feeding device for the vibratory feeder.

[0005] The automatic feeding device for a vibratory feeder provided in this application adopts the following technical solution: An automatic feeding device for a vibratory feeder includes: A hopper is used to hold materials. A hopper detection device is installed on the hopper, and the hopper detection device is used to detect the remaining amount of material in the hopper; An angle adjustment device is connected to the hopper and the hopper detection device. The angle adjustment device is used to drive the hopper to tilt so that the material falls into the vibrating plate. The angle adjustment device controls the tilt angle of the hopper according to the remaining amount of material in the hopper.

[0006] By adopting the above technical solution, when there is a lot of material in the hopper, the angle adjustment device can maintain a small tilt angle to prevent excessive material leakage. When the material in the hopper decreases, the angle adjustment device can automatically increase the tilt angle and use gravity compensation to maintain a relatively constant discharge flow rate. This makes the feeding process of the vibratory feeder smoother, more continuous, and more uniform. Through the closed-loop control of "detection-feedback-adjustment," the feeding process is fully automated, requiring no manual intervention, reducing labor costs, and ensuring the continuous and stable operation of the production line, thereby improving overall production efficiency.

[0007] Optionally, the angle adjustment device includes a rotating shaft, a half gear, and a drive motor. The hopper and the half gear are mounted on the rotating shaft. A drive gear is mounted on the output shaft of the drive motor. The drive gear meshes with the half gear. The drive motor is used to drive the drive gear to rotate, thereby causing the half gear to rotate and tilting the hopper.

[0008] By adopting the above technical solution, gear transmission has the advantages of constant transmission ratio and no slippage compared to belt transmission or friction transmission. This ensures that the rotation of the drive motor can be accurately and without error converted into the tilt angle of the hopper, achieving precise control of the feeding process.

[0009] Optionally, the angle adjustment device further includes a first support plate and an angle adjustment bracket, the angle adjustment bracket being disposed on the first support plate, the rotating shaft being rotatably disposed on the angle adjustment bracket, and the drive motor being disposed on the angle adjustment bracket.

[0010] By adopting the above technical solution, the first support plate provides a robust support platform, ensuring that key components such as the rotating shaft and drive motor can be installed and operated stably, guaranteeing the accuracy and repeatability of the angle adjustment action, and avoiding transmission errors or equipment damage caused by loose structure.

[0011] Optionally, the angle adjustment bracket is provided with a sliding groove, and a sliding rod is slidably disposed in the sliding groove, the sliding rod being used to lock the drive gear.

[0012] By adopting the above technical solution, the locking mechanism can fix the hopper at any specific angle when needed, effectively preventing accidental rotation and ensuring the safety of operators and maintenance personnel. At the same time, this also facilitates cleaning and maintenance of the hopper's interior or discharge port.

[0013] Optionally, the vibratory feeder automatic feeding device further includes a height adjustment device. The height adjustment device includes a second support plate, multiple sliding rods, multiple sleeve rods, and a telescopic cylinder. The sleeve rods are disposed on the second support plate, and the sliding rods are slidably disposed within the sleeve rods. The sliding rods are connected to the first support plate. The telescopic cylinder is disposed on the second support plate, and the telescopic end of the telescopic cylinder is connected to the first support plate. The telescopic cylinder is used to control the movement of the first support plate to drive the hopper to rise and fall.

[0014] By adopting the above technical solution, the height adjustment device allows the feeding device to be easily used with vibratory feeders or production lines of different heights without requiring major modifications to the equipment itself. It also facilitates installation, commissioning, and quick line changeovers.

[0015] Optionally, the hopper detection device includes a hopper detection bracket and a hopper detection sensor, wherein the hopper detection bracket is disposed on the hopper and the hopper detection sensor is disposed on the hopper detection bracket.

[0016] By adopting the above technical solution, the sensor is stably fixed at a specific position on the hopper using a bracket, ensuring the accuracy and stability of the detection, thereby providing reliable data input for subsequent angle adjustment and control.

[0017] Optionally, the automatic feeding device for the vibratory feeder further includes a vibratory feeder detection device, which includes a vibratory feeder detection bracket and a vibratory feeder detection lever. The vibratory feeder detection lever is mounted on the vibratory feeder detection bracket and is used to detect the remaining material in the vibratory feeder.

[0018] By adopting the above technical solution, the actual demand of the downstream equipment (vibratory feeder) is detected. Feeding is only triggered when the material in the vibratory feeder is indeed insufficient. This avoids overload of the vibratory feeder and material accumulation, making the entire system operate more intelligently and efficiently.

[0019] Optionally, the hopper is provided with a discharge port, which is located above the vibrating plate.

[0020] By adopting the above technical solution, it is ensured that the material can flow smoothly from the hopper into the vibrating plate by gravity, which is the basis for the realization of the function of the entire device.

[0021] Optionally, the hopper is provided with a plurality of material-pushing rods near the discharge port, the material-pushing rods being used to push the material passing through the discharge port.

[0022] By adopting the above technical solution, when the hopper is tilted and the material flows towards the discharge port, the push rod can play a role in stirring and guiding, effectively destroying the "bridging" structure of the material, ensuring that the material can be smoothly discharged from the discharge port even when the flowability is poor, and greatly expanding the range of applicable materials of the device.

[0023] Optionally, the hopper is also connected to a buffer plate, which is used to buffer the material passing through the discharge port.

[0024] By adopting the above technical solution, the buffer plate provides a cushioning transition for falling materials, effectively reducing the impact force. This protects the integrity of fragile materials, reduces wear and noise on the vibratory feeder surface, and helps maintain a stable material distribution within the vibratory feeder, further ensuring production quality and equipment lifespan.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When there is a lot of material in the hopper, the angle adjustment device can maintain a small tilt angle to prevent excessive material leakage. When the material in the hopper decreases, the angle adjustment device can automatically increase the tilt angle, using gravity compensation to maintain a relatively constant discharge flow rate. This makes the feeding process of the vibratory feeder smoother, more continuous, and more uniform. Through closed-loop control of "detection-feedback-adjustment," the feeding process is fully automated, requiring no manual intervention, reducing labor costs, and ensuring the continuous and stable operation of the production line, thereby improving overall production efficiency. 2. The first support plate provides a sturdy support platform, ensuring that key components such as the rotating shaft and drive motor can be installed and operated stably, guaranteeing the accuracy and repeatability of angle adjustment actions, and avoiding transmission errors or equipment damage caused by loose structure; 3. By using a bracket to stably fix the sensor at a specific position on the hopper, the accuracy and stability of the detection are ensured, thus providing reliable data input for subsequent angle adjustment and control; 4. The buffer plate provides a cushioning transition for falling materials, effectively reducing the impact force. This protects the integrity of fragile materials, reduces wear and noise on the vibratory feeder surface, and helps maintain a stable material distribution within the vibratory feeder, further ensuring production quality and equipment lifespan.

[0030] The hopper 10 is provided with a discharge port 11. Near the discharge port 11, the hopper 10 is provided with multiple material-pushing rods 12, which are used to push the material passing through the discharge port 11.

The angle adjustment bracket 32 ​​is mounted on the first support plate 31. The rotating shaft 33 is rotatably mounted on the angle adjustment bracket 32 ​​and connected to the hopper 10. The half gear 34 is mounted on the rotating shaft 33. The drive motor 35 is mounted on the angle adjustment bracket 32. A drive gear 36 is mounted on the output shaft of the drive motor 35. The drive gear 36 meshes with the half gear 34. The drive motor 35 drives the drive gear 36 to rotate, thereby tilting the hopper 10. The angle adjustment bracket 32 ​​also has a sliding groove 32a.

[0034] The control logic for the hopper detection sensor 22, the vibratory feeder detection lever 62, and the drive motor 35 is as follows: Material replenishment trigger: The vibratory feeder detection lever 62 detects that the vibratory feeder 50 is short of material and sends a "start replenishing" signal.

[0035] Feeding rate adjustment: After receiving the "start feeding" signal, the drive motor 35 starts to work, and its specific tilt angle is adjusted in real time by the signal of the hopper detection sensor 22 to achieve a stable feeding effect of "small angle when there is more material and large angle when there is less material".

[0036] The implementation principle of the automatic feeding device for a vibratory feeder in this embodiment is as follows: When there is a lot of material in the hopper 10, the angle adjustment device 30 can maintain a small tilt angle to prevent excessive material leakage; when the material in the hopper 10 decreases, the angle adjustment device 30 can automatically increase the tilt angle and use gravity compensation to maintain a relatively constant discharge flow rate. This makes the feeding process of the vibratory feeder 50 smoother, more continuous, and more uniform. Through the closed-loop control of "detection-feedback-adjustment", the feeding process is fully automated, requiring no manual intervention, reducing labor costs, and ensuring the continuous and stable operation of the production line, thereby improving overall production efficiency.
