Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying in mechanical manufacturing, in particular to a self-adaptive buffer conveying mechanism for micro part assembly. BACKGROUND

[0002] With the development of small unmanned aerial vehicles, micro robots and other products, the assembly of their core parts (size 2-10 mm, weight 0.1-5 g) relies on automatic conveying mechanisms, which require a conveying speed of 1-3 m / min, a part damage rate of ≤0.1%, a position deviation of ≤0.2 mm, and the ability to adapt to the conveying of different shaped parts (cylindrical, square, irregular).

[0003] Referring to the patent document CN114655711B, published on July 18, 2023, a small part pneumatic feeding buffer device is disclosed, which includes a bracket, a base, a cylinder, a baffle, a fixed block, and a pipe clamping assembly. The bracket is fixed above the installation equipment, and the upper soft tube is connected with the airflow nozzle at one end and is installed with the pipe clamping assembly at the other end. The lower soft tube is connected with the inlet of the installation equipment at one end and is installed with the pipe clamping assembly at the other end. The pipe clamping assembly includes a sleeve and a clamping block, the sleeve is provided with an annular groove at the bottom, the sleeve is inserted into the mounting hole of the fixed block, the fixed block is installed on the bracket and is provided with a pin hole at the side, the pin hole corresponds to the annular groove, and the limit pin is inserted into the pin hole to clamp the sleeve. The fixed block has two and is arranged in an upper and lower manner, a pullable baffle is arranged between the two fixed blocks, and a spring is arranged between the connecting bed plate and the baffle. The present application can eliminate the impact force of small parts and prevent small parts from being stuck in the installation equipment.

[0004] Based on the search of the patent number and the deficiencies in the prior art, it is found that:

[0005] The existing hard belt or metal track is often used for conveying micro parts. When the parts fall from the feeding device into the conveying track, there is no buffer, which easily causes collision and damage, with a damage rate of 3%-5%. Especially for thin-walled micro parts (such as 0.1 mm thick micro metal gaskets), damage is easily caused after collision, and position deviation is easily caused during high-speed conveying. In addition, special conveying tracks need to be replaced for different shaped parts (such as V-shaped groove track for cylindrical parts and flat bottom track for square parts), and the replacement time is 30-60 minutes, which affects the assembly efficiency. Furthermore, in the process of conveying micro parts, dust, oil stains or debris easily accumulate on the conveying guide rail, which affects the positioning accuracy and increases the risk of part contamination. SUMMARY

[0015] Preferably, a sliding groove is formed in the middle of one side of each of the two deflection plates, and the two limiting rods are slidingly clamped in the middle of the sliding groove.

[0016] Preferably, the outer side of the transmission shaft is fixedly provided with two symmetrically distributed driving blocks, and the two driving blocks are slidingly clamped in the middle of one side of the deflection plate.

[0017] Advantages

[0018] Compared with the prior art, the advantages of the present application are:

[0019] 1. The micro parts fall into the U-shaped track, and the silica gel buffer layer in the middle of the track absorbs the impact energy of the falling parts through deformation, avoiding direct collision of the parts with the hard track. Meanwhile, the polyurethane elastic barrier on the upper part of the U-shaped track can be automatically flipped by 0-30° through the micro torsional spring according to the width of the parts, which not only limits the parts horizontally, but also avoids rigid friction between the barrier and the parts. Through the synergistic effect of impact absorption of the silica gel buffer layer and flexible limiting of the elastic barrier, the problem of part damage rate of 3%-5% in the existing hard conveying track is effectively solved, and the damage rate of micro parts (especially thin-walled parts) can be controlled at a low level, significantly improving the integrity of the parts during conveying.

[0020] 2. The soft rubber micro positioning protrusions embedded in the silica gel buffer layer of the U-shaped track can form "multi-point support positioning" according to the shape of the part bottom (such as the deformation of the protrusions to both sides when the cylindrical part is extruded, and the local depression of the protrusions when the square part is extruded), limiting the part from rotating and deviating. Meanwhile, the micro air nozzle is arranged every 100mm at the side top end, and the 0.2-0.3MPa low-pressure air flow emitted by the nozzle acts on the part at an angle of 45°, which not only presses the part towards the buffer layer, but also corrects the positional deviation through "air flow guiding force", so that stable conveying of micro parts with a width of 3-10mm and different shapes (cylindrical, square, irregular) can be realized without replacing the track or positioning components, avoiding the cumbersome operation of replacing the special track of the existing equipment, and greatly improving the changeover efficiency and versatility of the assembly line.

[0021] 3. The application starts the driving motor to make the rotating disc and the driving rod drive the transmission shaft to reciprocate, and the rubber scraper always adheres to the silica gel buffer layer under the pressure of the spring, efficiently removing dust, oil stains and debris, avoiding the accumulation of dust, oil stains and debris, which affects the positioning accuracy and increases the risk of part contamination.

[0031] The cleaning assembly 22 is arranged on one side of the mounting plate 1 and is used for cleaning the upper surface of the U-shaped track 211.

[0032] The cleaning assembly 22 comprises two deflection plates 223 rotatably mounted on the opposite sides of the two mounting plates 1, the middle portions of the two deflection plates 223 are slidably clamped with a transmission shaft 221, the middle portion of the transmission shaft 221 is fixedly mounted with an oscillating plate 222, the two sides of the two mounting plates 1 are fixedly mounted with limiting rods 227, the upper portions of the two limiting rods 227 are sleeved with springs 225, the top ends of the two springs 225 are fixedly mounted on one side of the upper portion of the limiting rod 227, the bottom ends of the two springs 225 are fixedly mounted with pressing rings 226, the bottom ends of the two pressing rings 226 are in contact with the upper surface of the oscillating plate 222, and the pressing ring 226 is pressed downward to press the lower deflection plate 223, so that the oscillating plate 222 and the rubber scraper 2221 are always deflected to one side of the U-shaped track 211, and are in contact with the outer surface of the silica gel buffer layer 212, so that the oil stains and other impurities adhered to the surface are scraped off. One side of one of the mounting plates 1 is fixedly mounted with a mounting frame 228, the top end of the mounting frame 228 is fixedly mounted with a driving motor 2281, the driving end of the driving motor 2281 is fixedly mounted with a rotating disc 229, one side of the rotating disc 229 is movably mounted with a driving rod 2291, one side of the transmission shaft 221 is provided with a mounting groove 2292, the other end of the driving rod 2291 is movably mounted in the middle portion of one side of the mounting groove 2292. Under the drive of the driving motor 2281, the rotating disc 229 is driven to rotate, so that the eccentrically mounted driving rod 2291 is driven to reciprocatingly oscillate the transmission shaft 221, so that the oscillating plate 222 and the rubber scraper 2221 can reciprocatingly move, and the dust, oil stains and debris on the silica gel buffer layer 212 can be more efficiently cleaned.

[0033] The driving assembly comprises two synchronous rollers 2161 rotatably mounted in the middle portions of the two mounting plates 1, the outer sides of the two synchronous rollers 2161 are sleeved with synchronous belts 217 used in cooperation with each other, and the top end of the synchronous belt 217 is bonded to the upper surface of the two U-shaped tracks 211. One side of one of the mounting plates 1 is fixedly mounted with a servo motor 216, and one side of one of the synchronous rollers 2161 is fixedly mounted in the driving end of the servo motor 216. The servo motor 216 is a stepping motor. The synchronous roller 2161 is controlled to rotate by the stepping motor (rotation speed 50-150 r / min), so that the synchronous belt 217 and the U-shaped track 211 thereon are driven to move, the adjustable conveying speed of 1-3 m / min is realized, and then the micro parts are stably conveyed.

[0034] The upper surface of the synchronous belt 217 is bonded with evenly distributed anti-skid rubber particles 218, the bottom ends of the two U-shaped tracks 211 are in contact with the anti-skid rubber particles 218, the thickness of the anti-skid rubber particles 218 is 0.5 mm, and the particle size is 0.1 mm. The anti-skid rubber particles 218 can increase the friction between the U-shaped track 211 and the synchronous belt 217, and avoid slipping.

[0035] The middle part of one side of the two mounting plates 1 is provided with a micro photoelectric sensor 219, and the two micro photoelectric sensors 219 are used for detecting the part conveying speed in real time. The detection accuracy of the micro photoelectric sensor 219 is 0.05 mm, the part conveying speed is detected in real time, when the speed deviation exceeds ±5%, the micro photoelectric sensor 219 feeds back a signal to the controller, and the rotating speed of the stepping motor is adjusted to ensure the stability of the conveying speed.

[0036] One end of the swing plate 222 is fixedly provided with a rubber scraper 2221, and one side of the rubber scraper 2221 is in contact with the outer surface of the silica gel buffer layer 212. The rubber scraper 2221 can better fit the silica gel buffer layer 212 and the micro positioning protrusion 213, thereby ensuring more effective cleaning.

[0037] The middle part of one side of the two deflection plates 223 is provided with a sliding groove 224, and the two limiting rods 227 are slidingly clamped in the middle part of the sliding groove 224. When the deflection plate 223 moves downward on one side under the pressing of the pressing ring 226, the limiting rod 227 can move in the sliding groove 224, ensuring smooth deflection movement of the deflection plate 223.

[0038] The outer side of the transmission shaft 221 is fixedly provided with two symmetrically distributed driving blocks 2293, and the two driving blocks 2293 are slidingly clamped in the middle part of one side of the deflection plate 223. Through the driving block 2293, the connection between the transmission shaft 221 and the deflection plate 223 is more stable.

[0039] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0040] When working, first, according to the size specification of the micro parts to be conveyed, the splicing length of the U-shaped track 211 is adjusted through the sliding groove and sliding block structure between the U-shaped tracks 211 to meet the conveying demand. After starting the equipment, the servo motor 216 starts to work, and the servo motor 216 drives the synchronous roller 2161 connected thereto to rotate. Under the action of the synchronous roller 2161, the synchronous belt 217 moves, and in turn drives the U-shaped track 211 bonded on the synchronous belt 217 to move. When the micro part enters the U-shaped track 211, the silica gel buffer layer 212 on the upper surface of the middle part of the U-shaped track 211 deforms to absorb the impact energy when the part falls, preventing the part from being damaged due to collision. The micro positioning protrusion 213 on the upper part of the silica gel buffer layer 212 will deform according to the shape of the bottom of the part to form “multi-point support positioning” of the part, limiting the rotation and deviation of the part during the conveying process.

[0041] Meanwhile, the elastic baffle 214 on the upper part of the U-shaped track 211 can be automatically flipped according to the width of the parts, which can limit the transverse deviation of the parts and adapt to parts with different widths of 3-10 mm. During the conveying process of the parts, the micro air jet nozzle 215 at the side top end of the U-shaped track 211 sprays low-pressure air flow, the direction of the air flow is 45° to the conveying direction, the air flow pressure presses the parts to the silica gel buffer layer 212 at the bottom of the U-shaped track 211, and at the same time, the air flow forms a "air flow guiding force" to correct the position deviation of the parts during the conveying process, so as to ensure that the parts are conveyed along the correct path. The micro photoelectric sensor 219 in the middle of one side of the two mounting plates 1 detects the conveying speed of the parts in real time, and the detection accuracy is 0.05 mm. When the detected speed deviation exceeds ±5%, the micro photoelectric sensor 219 feeds back a signal to the controller, and the controller adjusts the rotating speed of the servo motor 216 to ensure the stability of the conveying speed of the parts.

[0042] During the entire conveying process, the cleaning assembly 22 continuously cleans the upper surface of the U-shaped track 211. The driving motor 2281 drives the rotating disc 229 to rotate, the rotating disc 229 drives the transmission shaft 221 to reciprocate through the eccentric driving rod 2291, and then drives the swing plate 222 and the rubber scraper 2221 at one end of the swing plate 222 to reciprocate. At the same time, the spring 225 pushes the compression ring 226 to press the deflection plate 223, so that the rubber scraper 2221 is always in close contact with the outer surface of the silica gel buffer layer 212, which can efficiently remove dust, oil stains, debris and other impurities attached to the silica gel buffer layer 212, and ensure the cleanliness of the conveying environment.
