Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to an automatic feeding device and an automatic feeding system. Background Technology

[0002] With the improvement of automation, small and micro materials are generally fed by vibrators. Vibrators are usually less than 300mm in diameter, and the vibratory plate can only hold 2000pcs-4000pcs at a time. It requires a 2-hour shutdown and manual replenishment of the vibratory plate. At the same time, due to the constraints of equipment space and material appearance requirements, the diameter of the vibrator cannot be made large, and the machine can only be stopped to replenish the material.

[0003] Downtime affects approximately 1% of time utilization and requires an additional 0.2 people per line. There are over 1,000 various types of vibrating equipment. Downtime results in a loss of nearly 300-500 hours per day, with nearly 4 million downtimes annually, totaling 75,000 hours of downtime. This restricts the production line's UPH (Units Per Hour) and automation level. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] On the one hand, this utility model embodiment provides an automatic feeding device 1, such as... Figure 1-6 As shown, the device includes a support 11, on which a storage bin 12 and a vibrator 13 are fixedly mounted. The storage bin 12 is funnel-shaped, with a buffer slide 14 below the bottom outlet. A discharge adjustment plate 15 is mounted on the buffer slide 14, and a material-pushing rod 16 passes through the bottom outlet of the storage bin 12. The vibrator 13 is located below the buffer slide 14 and drives the buffer slide 14 and the material-pushing rod 16. In a specific implementation, the vibrator 13 can be a linear vibrator, with its vibration direction along the length of the buffer slide 14, to improve the effect of vibration in driving material discharge.

[0021] In use, the material is placed into the storage bin 12 of the automatic feeding device 1. A feeding rod 16 is inserted into the bottom discharge port of the storage bin 12. The vibrator 13 drives the feeding rod 16. Under the action of the feeding rod 16, the material falls through the bottom discharge port of the storage bin 12 onto the buffer slide 14. Then, it is discharged to the receiving device 2 (which can be the vibrating plate shown in the figure) through the buffer slide 14. The buffer slide 14 is equipped with a discharge adjustment plate 15. By adjusting the height of the discharge adjustment plate 15 (up and down), the discharge speed and quantity can be controlled.

[0022] In specific implementation, the buffer slide 14 can be horizontally set or inclined at an angle towards the receiving device 2. The inclination angle can be flexibly set according to requirements. In this embodiment of the utility model, it is preferably 3 degrees to 5 degrees. The storage tank 12 can be a non-magnetic tank with an inclined angle, so that it can be compatible with a variety of materials (including magnetic materials). The materials can be various (rigid) materials / parts required for assembling products. For example, the product can be headphones, and the materials can be magnets, yokes, voice coils, and the shells of vibrating units in headphones.

[0023] The automatic feeding device 1 of this utility model has a funnel-shaped storage bin 12, which can hold more types and quantities of materials without the need for multiple manual refills (only one feeding per day is required), greatly improving production efficiency and reducing labor costs. A buffer slide 14 is provided below the bottom discharge port of the storage bin 12, and a discharge adjustment plate 15 is provided on the buffer slide 14. Adjusting the height of the discharge adjustment plate 15 can control the discharge speed and quantity. The buffer slide 14 can reduce the impact force of the falling material and prevent fragile materials from colliding, breaking or deforming when falling directly, which is especially suitable for materials with requirements on surface or structure. A material guide rod 16 is inserted into the bottom discharge port of the storage bin 12. The material guide rod 16 can effectively prevent the material from blocking the bottom of the storage bin 12, ensuring that the material can flow out continuously and evenly, avoiding interruption of the feeding and ensuring the stable operation of the production line.

[0024] like Figure 1-2 As shown, in some embodiments of this utility model, the bracket 11 may include a guide shaft base 111 and a guide shaft 112 fixed to the guide shaft base 111. An upper mounting plate 113 and a lower mounting plate 114 are sequentially fixed on the guide shaft 112. The storage tank 12 is fixed to the upper mounting plate 113, and the vibrator 13 is fixed to the lower mounting plate 114. It is conceivable that the bracket 11 may also be in other forms, such as a square frame. Compared with a frame-type bracket, since the receiving device 2 is usually already in a fixed position in the renovation project, the vertical integrated design formed by the guide shaft base 111 and the guide shaft 112 is convenient to install on the side of the existing receiving device 2, occupies less space, and is also convenient to install or replace related components (such as the storage tank 12, vibrator 13, upper mounting plate 113, lower mounting plate 114, etc.).

[0025] In practice, the guide shaft base 111 and the guide shaft 112 can be welded together. For ease of implementation, the guide shaft base 111 is connected to the guide shaft 112 using a set screw (the embodiment shown in the figure is connected by a set screw), thus enabling 360-degree angle adjustment.

[0026] The upper mounting plate 113 and the lower mounting plate 114 can be fixed to the guide shaft 112 in various ways, such as welding or snap-fitting. In some embodiments of this utility model, the upper mounting plate 113 can be fixed to the guide shaft 112 by the upper clamping block 1131 and the upper clamping bolt 1132; the lower mounting plate 114 can be fixed to the guide shaft 112 by the lower clamping block 1141 and the lower clamping bolt 1142. In this way, both the upper mounting plate 113 and the lower mounting plate 114 can be adjusted in multiple angles and heights, and can be compatible with the specifications of various material receivers 2, storage tanks 12 and vibrators 13.

[0027] In practice, the (linear) vibrator 13 can be fixed to the buffer slide 14, the feeding rod 16 and the lower mounting plate 114 respectively by screws. At the same time, the buffer slide 14, the vibrator 13, the lower mounting plate 114 and the guide shaft 112 can be locked together to realize rotation in all directions and height adjustment, which facilitates the adjustment of the placement height and angle of the material and is compatible with receiving devices of different specifications and sizes.

[0028] In some embodiments of this utility model, a clamping plate 115 may be provided at the end of the upper mounting plate 113 away from the guide shaft 112. Both the upper mounting plate 113 and the clamping plate 115 have clamping openings on their opposite end faces for the bottom discharge port of the storage bin 12 to pass through. The clamping plate 115 is fixed to the upper mounting plate 113 by bolts (not shown). In this way, the clamping opening formed by the clamping plate 115 and the upper mounting plate 113 can adjust the height of the storage bin 12, and it is convenient to replace the storage bin 12 when using different materials. At this time, the discharge adjustment plate 15 can be fixed to the end of the clamping plate 115 away from the upper mounting plate 113. In specific implementation, flexible and precise adjustments can be made according to the needs of the receiving device 2 to avoid excessively fast discharge leading to accumulation or excessively slow discharge affecting efficiency.

[0029] In some embodiments of this utility model, the discharge adjustment plate 15 may be provided with a vertically extending first sliding hole 151, and a bolt 150 for fixing the discharge adjustment plate 15 to the clamping plate 115 is provided in the first sliding hole 151. Compared with the design of multi-level fixed holes, the sliding hole structure supports locking at any position, the adjustment is more precise, and it can meet the more accurate control of the discharge speed. Moreover, when changing materials (such as parts of different lengths and diameters), the gap between the discharge adjustment plate 15 and the buffer slide 14 can be adjusted through the first sliding hole 151, which is convenient to use.

[0030] like Figure 3As shown, in some embodiments of this utility model, the upper end of the discharge adjustment plate 15 may be provided with an upper bending portion 152, and a support member 17 is provided on the upper bending portion 152. The support member 17 extends from the upper bending portion 152 toward one end near the buffer slide 14 and has a first material detection switch 191 (specifically, a photoelectric detection switch) at its end for detecting the presence or absence of material in the buffer slide 14. In specific implementation, the support member 17 has a connecting portion 171 connected to the upper bending portion 152, a support platform 172 supporting the first material detection switch 191, and a vertically extending extension portion 173 between the two. The support member 17 may specifically be Z-shaped.

[0031] In this way, the upper bending part 152 extending from the upper end of the discharge adjustment plate 15 serves as the base for sensor installation, eliminating the need for additional independent brackets and maximizing space utilization. The first material detection switch 191 can monitor in real time whether there is material passing through or accumulating in the buffer slide 14 (specifically, the area outside the discharge adjustment plate 15), making it convenient to use.

[0032] In some embodiments of this utility model, the lower end of the discharge adjustment plate 15 may be provided with a lower bend 154. The lower bend 154 can form a smooth transition edge to prevent the material from being scratched and improve the product yield. Moreover, the lower bend 154 can cooperate with the buffer slide 14 to form a closed discharge channel on all sides to prevent small parts from accidentally popping out when passing through the discharge adjustment plate 15.

[0033] like Figure 4 As shown, in some embodiments of this utility model, the bracket 11 may also be provided with an extension rod 18 (specifically, it can be set on the guide shaft 111 or the upper mounting plate 113; in the embodiment shown in the figure, it is set on the clamping plate 115). The end of the extension rod 18 is used to extend into the receiving device 2 and is provided with a second material detection switch 192 (specifically, a photoelectric detection switch) for detecting whether there is material on the discharge path of the receiving device 2. In specific implementation, the extension rod 18 includes a horizontal rod 181 and a vertical rod 182. The horizontal rod 181 and the vertical rod 182 are movably connected by a clamping block, so the extension rod 18 can be adjusted up and down and back and forth, which is convenient for matching with receiving devices 2 of different specifications and sizes. Moreover, using the extension rod 18 as a base for sensor installation results in high space utilization. When the second material detection switch 192 detects that the material in the receiving device 2 is lower than the lower limit, the automatic feeder (i.e., the automatic feeding device 1) starts feeding material and stops feeding when the material is full.

[0034] Continue as Figure 1-2 As shown, in some embodiments of this utility model, one end of the buffer slide 14 is closed, and the other end is provided with an adjustable-angle extension slide 140. The adjustable-angle extension slide 140 can extend the length of the buffer slide 14, so that it can extend to the feeding position of the feeder 2, so that the material can be accurately fed into the feeding position.

[0035] The end side walls of the buffer slide 14 may be provided with laterally extending second sliding holes 141. The end of the extension slide 140 near the buffer slide 14 covers the end of the buffer slide 14. The end side walls of the extension slide 140 near the buffer slide 14 are provided with through holes (not shown). Fixing pins 142 (specifically bolts) pass through the second sliding holes 141 and the through holes. In this way, the extension slide 140 can adjust its angle, thereby slowing down the falling speed of the material and reducing material defects.

[0036] The feed lever 16 can take various structural forms that are easily conceived by those skilled in the art. For ease of implementation, a preferred form is, for example... Figure 3 As shown, the feeding rod 16 is a bamboo-joint shaped feeding rod. The portion of the feeding rod 16 inside the bottom discharge port of the storage hopper 12 may include at least one bamboo joint. Thus, the bamboo-joint shaped feeding rod 16 can slow down the falling speed of the material and agitate the stacked sheet material for discharge. The upper end of the feeding rod 16 can extend beyond the bottom discharge port of the storage hopper 12 into the main body of the storage hopper 12. The portion of the feeding rod 16 extending into the main body of the storage hopper 12 includes at least one bamboo joint. In this way, multi-level feeding and layered disturbance can be achieved, thereby avoiding the phenomenon of "central flow" or "eccentric flow" and improving the uniformity of material supply.

[0037] In some embodiments of this utility model, the feeding rod 16 can be made of POM (Polyoxymethylene) non-metallic material. POM material will not damage the material and is also suitable for magnetic materials.

[0038] In some embodiments of this utility model, the ratio of the inner diameter of the bottom outlet of the storage hopper 12 to the maximum outer diameter of the feeding rod 16 is 3.8-6.5, for example, it can be 4, 5, 6, etc. In specific implementation, it can be flexibly set according to the size of the material, so as to ensure that the material will not be stuck and will not fall too fast. The feeding rod 16 can be cylindrical, and a bamboo joint is formed by setting an arc groove 160 on the cylinder. The minimum inner diameter L1 of the feeding rod 16 is 4.8mm-6.2mm, for example, it can be 5mm, 5.5mm, 6mm, etc., and the maximum outer diameter L2 of the feeding rod 16 is 10mm-13mm, for example, it can be 10.5mm, 11.5mm, 12mm, etc., and further, the radius of the arc groove 160 can be selected to be 34mm-45mm, for example, it can be 35mm, 40mm, 43mm, etc., so as to better ensure the strength of the feeding rod 16 and The service life, especially the size selection of the arc groove 160, combined with the previous feature (the ratio of the inner diameter of the bottom outlet to the maximum outer diameter of the feeding rod 16 is 3.8-6.5), allows the material in the bottom outlet to slightly stack in the arc groove 160 above a bamboo joint. During the process of the vibrator 13 driving the feeding rod 16 to reciprocate, the material stacked in the arc groove 160 can fall in an orderly and controllable manner, thereby achieving the best feeding and material control effect, ensuring that the material can flow out continuously and evenly, avoiding material supply interruption, and ensuring the stable operation of the production line.

[0039] The lower end of the feed rod 16 can be provided with a stepped connector 161, which includes a large-diameter section 1611 and a small-diameter section 1612. The vibrator 13 is provided with a feed rod mounting hole 131. The large-diameter section is fixed to the feed rod mounting hole 131, and the small-diameter section 1612 passes through the bottom wall of the buffer slide 14 and is fixed to the lower end of the feed rod 16. In this way, the transmission efficiency of the vibrator 13 can be improved, resulting in better performance.

[0040] On the other hand, embodiments of this utility model provide an automatic feeding system, such as... Figure 6 As shown, it includes the receiving device 2 and the aforementioned automatic feeding device 1. The structure of the automatic feeding device 1 is the same as above, and will not be described again here.

[0041] The automatic feeding system of this utility model includes an automatic feeding device 1. The storage bin 12 of the automatic feeding device 1 is funnel-shaped, which can hold more types and quantities of materials without the need for multiple manual replenishments (only one feeding per day is required), greatly improving production efficiency and reducing labor costs. A buffer slide 14 is provided below the bottom discharge port of the storage bin 12. A discharge adjustment plate 15 is provided on the buffer slide 14. Adjusting the height of the discharge adjustment plate 15 can control the discharge speed and quantity. The buffer slide 14 can reduce the impact force of the falling material and prevent fragile materials from colliding, breaking or deforming when falling directly. It is especially suitable for materials with requirements on surface or structure. A material guide rod 16 is inserted into the bottom discharge port of the storage bin 12. The material guide rod 16 can effectively prevent the material from blocking the bottom of the storage bin 12, ensuring that the material can flow out continuously and evenly, avoiding interruption of the feeding and ensuring the stable operation of the production line.

[0042] In summary, this utility model proposes a universal and standardized automatic feeding mechanism, aiming to solve the problem of requiring multiple manual feedings for small processed parts with high requirements for appearance, quality, etc. This utility model has the following characteristics: 1. This utility model addresses the difficulty of manually feeding small and micro materials such as magnetic circuit components during machine downtime by designing a universal and standardized automatic feeding device, thereby realizing automatic feeding of the receiving device; 2. By designing a multi-directional adjustable mechanism, multi-degree-of-freedom spatial adjustment is achieved, making it compatible with various vibrators and enabling 360-degree directional adjustment. 3. By designing a new bamboo-shaped material feeding scheme, the problem of irregular thin sheet materials being easily stacked and jammed was solved, and compatibility with multiple types of materials was achieved.

[0043] In addition, this utility model has the following advantages: 1. Enables material discharge from various directions and heights, compatible with various sizes and heights of material receiving mechanisms with diameters up to 360mm, facilitating integration into various equipment units; 2. The bamboo-shaped material feeding rod driven by the linear vibrator solves the problem of thin and light materials easily stacking and getting stuck in the storage bin; 3. By adjusting the height of the discharge regulating plate, the quantity and speed of material discharge can be adjusted. 4. Cost advantage: The fiber optic testing bracket, storage tank, guide shaft and guide shaft base adopt standardized modules, which have a certain cost advantage.

[0044] This patent application can replace the manual feeding solution. It is estimated that nearly 2,000 units can be promoted within the company. After full promotion, the number of downtimes will be reduced by about 12,000 times / day, and the downtime will be reduced by about 400 hours / day, reducing the frequency and duration of downtime by 90%. The equipment utilization rate will be increased by about 1%, and the number of workers per line will be reduced by 0.2, resulting in an estimated saving of 32 workers.
