Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figures 1 to 5A feeder for transferring resistor and inductor chips according to an embodiment of the present invention includes an electromagnetic vibrator (1) disposed at the bottom of a feeding main board (2); the surface of the feeding main board (2) is provided with a first channel (21) and a second channel (22), the inlet width of the first channel (21) is equal to the width of the feeding main board (2), and gradually narrows inward along the material transfer direction, the second channel (22) is connected to the narrowed end of the first channel (21) and is of equal width; a height limiting device (3) includes a first height limiting baffle (31) and a second height limiting baffle (32), the first height limiting baffle (31) is disposed on the inlet side of the first channel (21), and the second height limiting baffle (32) is disposed at the connection between the first channel (21) and the second channel (22); the height limiting device (3) also includes two adjusting press valves (33), the adjusting press valves (33) are used to adjust the height of the first height limiting baffle (31) and the second height limiting baffle (32). The electromagnetic vibrator (1) is fixed to the bottom of the feeding main board (2) by bolts. After being powered on, it generates high-frequency vibration, driving the material on the main board (2) to move along the first channel (21). The inlet width of the first channel (21) is the same as that of the main board (2) (e.g., 80mm). After the material enters, it gradually narrows along the inward direction to the width of the second channel (22) (e.g., 5mm), realizing the conversion from parallel to vertical arrangement. The first height limit baffle (31) is located on the inlet side. Its height is adjusted by adjusting the pressing valve (33) to limit the number of material layers passing through at one time. The second height limit baffle (32) is located at the channel connection to further control the flow rate of material entering the second channel (22). During the vibration process, the material moves in an orderly manner under the constraint of the height limit baffle and is finally output to the downstream station through the second channel (22).

[0026] Please see Figures 1 to 5 In another embodiment, both ends of the first height limiting baffle (31) and the second height limiting baffle (32) are provided with support platforms (35). The bottom of the support platform (35) is provided with a slot (36), and a spring (37) is installed in the slot (36). The height limiting baffle is fixed to the side strip (23) of the feeding main board (2) by a groove (38). The support platform (35) is a rectangular steel block, welded to both ends of the first height limiting baffle (31) and the second height limiting baffle (32). The bottom of the support platform (35) is provided with a slot (36), and a stainless steel spring (37) is embedded in the slot (36). The height limiting baffle is inserted into the side of the side strip (23) of the feeding main board (2) by the groove (38). The width of the groove (38) matches the thickness of the side strip (23) (e.g., 2mm), so that the baffle is vertically fixed. When the material hits the baffle, the spring (37) is compressed to absorb the impact force, preventing the baffle from deforming or breaking; after the vibration stops, the spring (37) rebounds to its original position, ensuring that the baffle maintains the preset height.

[0027] Please see Figures 1 to 5In another embodiment, the adjusting pressure valve (33) includes a rotary valve (331) and a support frame (34). The support frame (34) is fixedly mounted on both sides of the feeding main board (2). The rotary valve (331) is threaded onto the top of the support frame (34). One end of the rotary valve (331) abuts against the support platform (35) and is opposite to the slot (36). The height of the height limiting baffle is adjusted by rotating the rotary valve (331) to compress the spring (37). The support frame (34) is an L-shaped steel piece, which is fixed to the two sides of the feeding main board (2) by bolts, and has an internal threaded hole machined on the top. The rotary valve (331) has a cylindrical structure, with an M4 fine thread matching the support frame (34) on its outer surface, and a flat end at the bottom. When the rotary valve (331) is rotated, its bottom flat end presses downward against the slot (36) area of ​​the support platform (35), compressing the spring (37), thereby pushing the first height limit baffle (31) and the second height limit baffle (32) downward as a whole; when rotated in the opposite direction, the spring (37) rebounds, causing the baffle to rise. The baffle height can be adjusted by 0.5mm for each rotation, achieving micron-level precision control.

[0028] Please see Figures 1 to 5 In another embodiment, the feeding main board (2) is further provided with multiple guide plates (24), which are arranged at intervals along the direction of the first channel (21) and the second channel (22) to form guide channels (25). The guide plates (24) are long strips of stainless steel sheets, which are fixed to the surface of the feeding main board (2) by countersunk bolts, and are arranged symmetrically on both sides of the center line of the first channel (21) and the second channel (22), forming guide channels (25) with a width of 5mm at intervals. During vibration, the material is constrained by the side walls of the guide plates (24) and can only move along the axial direction of the channel, avoiding lateral displacement or stacking.

[0029] Please see Figures 1 to 5 In another embodiment, the end of the second channel (22) is inclined downward at an angle of 10°-30°. The end of the second channel (22) is milled to form a 15° inclined surface, with the inclination direction consistent with the material conveying direction. When the material moves to the end, it accelerates down the channel under the action of gravity, reducing its dependence on vibration energy. At the same time, the inclination angle prevents the material from rushing out of the channel due to inertia.

[0030] Please see Figures 1 to 5 In another embodiment, the feeding main board (2) is an integrally formed aluminum structure with anti-slip texture on the surface.

[0031] The feeding main board (2) is made of 6061 aluminum alloy and is integrally machined by CNC milling. The surface is machined with diamond-shaped anti-slip texture with a depth of 0.3mm. Aluminum material is lightweight (40% lighter than steel main board) and easy to process complex channel structures; the anti-slip texture increases the friction between the material and the main board, preventing the material from slipping or stopping during vibration.

[0032] Please see Figures 1 to 5 In another embodiment, the electromagnetic vibrator (1) has a frequency range of 50Hz-200Hz and an amplitude of 0.1mm-0.5mm. The electromagnetic vibrator (1) controls its frequency via a frequency converter. At a low frequency of 50Hz, the amplitude is 0.5mm, suitable for the slow conveying of large-sized materials (such as 5mm×5mm chips); at a high frequency of 200Hz, the amplitude is 0.1mm, suitable for the rapid and dense feeding of small-sized materials (such as 1mm×0.5mm chips). The amplitude and frequency are adjusted in conjunction to ensure smooth material movement under different working conditions.

[0033] Please see Figures 1 to 5 In another embodiment, the spacing of the guide plates (24) is 1.2-1.5 times the width of the material. Taking a material width of 2mm as an example, the spacing of the guide plates (24) is set to 2.4mm (1.2 times). This spacing allows the material to oscillate slightly within the channel without deviating from the guide path, while avoiding material deviation or jamming due to excessive spacing.

[0034] Please see Figures 1 to 5 In another embodiment, the inward angle of the first channel (21) is 5°-15°. The first channel (21) is formed with a 10° inward angle by milling, and the inlet width gradually narrows from 80mm to 5mm. If the inward angle is too small (e.g., 5°), it will prolong the channel length and reduce efficiency; if it is too large (e.g., 15°), it will easily lead to material congestion. The 10° angle balances the transfer speed and smoothness.

[0035] Please see Figures 1 to 5 In another embodiment, the surfaces of the first height-limiting baffle (31) and the second height-limiting baffle (32) are covered with a wear-resistant ceramic layer. The surfaces of the first height-limiting baffle (31) and the second height-limiting baffle (32) are covered with an alumina ceramic layer with a thickness of 0.2 mm and a hardness of HV1200 by plasma spraying. The ceramic layer reduces frictional wear between materials (such as ceramic-based chips) and the baffle, avoids scratching the chip surface, and extends the service life of the baffle to more than 100,000 cycles.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
