Description

Technical Field

[0001] This utility model belongs to the field of motorcycle technology, and in particular relates to a high-efficiency automated feeding bin for motorcycle engine connecting rods. Background Technology

[0002] Motorcycles are a common mode of transportation. The engine, as the core component, provides the power source for the motorcycle's movement, and the crankshaft system is the heart of the engine. During engine operation, the connecting rod, as the main transmission component of the crankshaft system, converts the reciprocating linear motion of the piston caused by the combustion of fuel and gas in the cylinder into the rotational motion of the crankshaft. Currently, small-displacement motorcycle crankshafts are generally assembled, their main structure consisting of the left / right crankshaft and the crank pin connecting them, while the connecting rod is a one-piece structure (the large end of the connecting rod is a single piece, requiring no bolt connection). The connecting rod large end bore and the crank pin are connected by a rolling bearing. Generally, the tolerance between the connecting rod large end bore, the rolling bearing, and the crank pin is in the micrometer range. The assembly precision of the connecting rod has a significant impact on the crankshaft system and even the overall performance of the engine. Problems in the connecting rod assembly process can cause abnormal engine noise, reduced power output, abnormal crankshaft wear, and in severe cases, crankshaft seizure, connecting rod breakage, and serious traffic accidents.

[0003] In the automated production of crankshafts for small-displacement motorcycles, the common method for loading connecting rods is: manual placement followed by conveyor belt transport and robot retrieval. The typical process involves workers placing the connecting rods one by one onto a positioning mechanism on the conveyor belt. Then, a motor drives the conveyor belt to transport the connecting rods to the automated loading station, where they await robot pickup. This method uses a planar conveyor system, which offers advantages in product adaptability but also suffers from limited hopper capacity. A 2-meter-long, 30-centimeter-wide conveyor belt laid flat can only hold 36 connecting rods. In actual production, stacking is generally used to increase hopper capacity (increasing the number of parts loaded at once), thereby reducing the frequency of manual loading and improving loading efficiency. However, because the linkage positioning mechanism on the conveyor belt needs to avoid gaps in the gripping position while ensuring product compatibility (reducing production changeover time), the positioning structure has a large false position. Therefore, in the case of linkage stacking, the positioning consistency deteriorates (error ±2mm). Furthermore, the frequent start-stop cycles of the conveyor belt will further deteriorate the linkage positioning accuracy due to inertia. Occasionally, this may cause the robot to stop due to interference with the robot's gripping operation during the robot loading process, requiring time for debugging and resetting, resulting in low efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a highly efficient and automated feeding bin for motorcycle engine connecting rods. This bin has a large capacity, high positioning accuracy, and high compatibility, effectively solving the current industry problem that the capacity of the connecting rod feeding bin, the accuracy of feeding and positioning, and the compatibility of the product cannot be achieved simultaneously.

[0005] This utility model is achieved through the following technical solution: A high-efficiency automated feeding bin for motorcycle engine connecting rods includes a base, a front support, a rear support, and multiple slide rods. The front and rear supports are spaced apart on the base. Multiple baffles are spaced apart along the length of the front support. The multiple slide rods are arranged in parallel. One end of each slide rod is attached to one of the baffles, and the other end is attached to the rear support. The slide rods are inclined downwards along the direction from the rear support to the front support. Adjacent slide rods form a slide track for the connecting rod to slide. The baffles are provided with blocking protrusions to block the connecting rod.

[0006] Furthermore, the rear support is equipped with an adjustment mechanism for adjusting the installation height of the slide rod.

[0007] Furthermore, the rear support includes two first columns spaced apart on the base. The first columns are provided with elongated holes and support protrusions. The elongated holes are located above the support protrusions. The adjustment mechanism includes a rear crossbeam and two long bolts. The two ends of the rear crossbeam are slidably disposed in the elongated holes of the two first columns. The bottom ends of the two long bolts are threadedly connected to the support protrusions of the two first columns, and the top ends of the long bolts are in contact with the rear crossbeam. A sliding rod is disposed on the rear crossbeam.

[0008] Furthermore, the front support includes a second connecting plate and two second columns, which are spaced apart on the base. The second connecting plate is connected to the top of the two second columns respectively. The bottom of multiple baffles is connected to a mounting plate, which is connected to the middle of the two second columns respectively.

[0009] Furthermore, the baffle includes a connecting part and a mounting part. The width of the connecting part is smaller than the width of the mounting part. The connecting plate is disposed on the mounting plate, the sliding rod is disposed on the mounting part, and the blocking protrusion is disposed on the mounting part.

[0010] Furthermore, it also includes an oil receiving tray, which is located below multiple slide bars.

[0011] Furthermore, a sensor is installed at the end of the slide to detect whether the connecting rod is in position.

[0012] Furthermore, the base includes a base plate and a support frame disposed at the bottom of the base plate.

[0013] Compared to existing technologies, the advantages of this invention are as follows: By employing a slide rail structure, the large end of the connecting rod is placed between two round sliding rods, allowing the connecting rod to be placed vertically on the slide rail. Automatic feeding is achieved by relying on the weight of the connecting rod and the tilt angle of the round sliding rods, eliminating the need for an additional power source, reducing energy consumption by 100%, and lowering production costs. The connecting rod is blocked at the end of the slide rail by a blocking protrusion, enabling it to self-correct its positioning during the sliding process under gravity, resulting in high positioning accuracy and improving the stability and positioning accuracy of the connecting rod feeding. Furthermore, a single slide rail can accommodate multiple connecting rods, and the slide rail is also compatible with connecting rods of various sizes. This invention features a large hopper capacity, high positioning accuracy, and high compatibility in connecting rod feeding. Its compact and efficient layout significantly reduces the floor space required, lowering the difficulty and cost of production line layout. It effectively solves the current industry problem of the incompatibility between connecting rod hopper capacity, feeding positioning accuracy, and product compatibility. Attached Figure Description

[0021] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the front end of the high-efficiency automated feeding bin for motorcycle engine connecting rods according to this utility model. Figure 2 for Figure 1 Enlarged diagram of part A, Figure 3 This is a partial rear view of the high-efficiency automated feeding bin for motorcycle engine connecting rods according to this utility model. Figure 4 for Figure 3 Enlarged diagram of part B, Figure 5 for Figure 1 A cross-sectional view (AA). A high-efficiency automated feed bin for motorcycle engine connecting rods includes a base 1, a front support 2, a rear support 3, and multiple slide rods 4. The front support 2 and the rear support 3 are spaced apart on the base 1. Multiple baffles 5 are spaced apart along the length of the front support 2. The multiple slide rods 4 are arranged in parallel. One end of the multiple slide rods 4 is set on the multiple baffles 5, and the other end of the multiple slide rods 4 is set on the rear support 3. The slide rods 4 are inclined downward along the direction from the rear support 3 to the front support 2. Adjacent slide rods 4 form a slide for the connecting rod 9 to slide. The baffles 5 are provided with blocking protrusions 51 for blocking the connecting rod 9.

[0022] During operation, a robot or operator places the connecting rod 9 within a slide rail formed by two adjacent sliding rods 4, ensuring that the larger end of the connecting rod 9 rests on the two sliding rods 4. The sliding rods 4 have circular cross-sections, and positioning is achieved through the contact of the curved surfaces of the sliding rods 4 on both sides of the outer contour of the larger end of the connecting rod 9. This minimizes the contact area and effectively limits the movement, reducing the possibility of surface damage to the connecting rod 9. Furthermore, this design allows for compatibility with connecting rods 9 of various sizes, such as... Figure 2 As shown. This setup avoids the need for manual stacking of link 9, reduces the difficulty of material loading operations, and minimizes downtime caused by robot interference during material handling.

[0023] Because the slide bar 4 is tilted, the connecting rod 9 automatically slides down the slideway under gravity. The slideway design balances sliding speed and stability, ensuring smooth sliding of the connecting rod 9 and achieving millimeter-level precise positioning. Simultaneously, the circular cross-section of the slide bar 4 reduces wear during the sliding and conveying process, extending its lifespan. When the connecting rod 9 reaches the bottom of the slideway and is picked up by the blocking protrusion 51, it stops at the bottom of the slideway. At this point, the robotic arm extends and picks up the lowest connecting rod 9. Subsequent connecting rods 9 automatically slide down to the picking position at the bottom of the slideway due to gravity, achieving continuous feeding. The blocking protrusion 51 has a small area, preventing the connecting rod 9 from falling with minimal contact area, avoiding damage to the surface of the connecting rod 9, while not hindering the robotic arm's picking up of materials. In one embodiment, the area of ​​the blocking protrusion 51 is 1.2 cm². In one embodiment, the baffle 5 includes a connecting portion 52 and a mounting portion 53. The width of the connecting portion 52 is smaller than the width of the mounting portion 53. The connecting plate is disposed on the mounting plate 7, the sliding rod 4 is disposed on the mounting portion 53, and the blocking protrusion 51 is disposed on the mounting portion 53. The baffle 5 is wider at the top and narrower at the bottom to ensure that it does not obstruct the robotic arm from grasping the connecting rod 9.

[0024] In one embodiment, a sensor is provided at the end of the slide to detect whether the connecting rod 9 is in position. By adding a sensor at the end of the slide to detect whether the connecting rod 9 is in position, when the connecting rod 9 slides to the end of the slide, the sensor detects that the connecting rod 9 is in position, sends a signal, and the robot arm receives the signal and removes the connecting rod 9 from the end of the slide. In one embodiment, the surface roughness of the circular slide rod 4 reaches Ra0.8μm, which greatly reduces the coefficient of friction when the connecting rod 9 slides down, preventing jamming during the sliding process.

[0025] This utility model provides a highly efficient automated feeding bin for motorcycle engine connecting rods. Automatic feeding is achieved by the weight of the connecting rod 9 and the tilt angle of the sliding rod 4. Automatic conveying is possible without an additional power source, reducing energy consumption by 100% and lowering production costs. The connecting rod 9 is blocked at the end of the slide by the blocking protrusion 51, allowing it to self-correct its positioning during the sliding process under gravity. This high positioning accuracy improves the stability and positioning precision of the connecting rod feeding. Furthermore, a single slide can accommodate multiple connecting rods 9, and the slide can also accommodate connecting rods 9 of various sizes.

[0026] This invention significantly optimizes space utilization and increases hopper capacity through a slide rail design, resulting in a large hopper capacity. Furthermore, it features a high-precision and highly compatible connecting rod 9 feeding system. Its compact and efficient layout greatly reduces the floor space required, lowering the difficulty and cost of production line layout. It effectively solves the current industry problem of the incompatibility between hopper capacity, feeding positioning accuracy, and product compatibility.

[0027] Please refer to the following: Figure 6 , Figure 6 for Figure 5 An enlarged schematic diagram of part C is shown. In one embodiment, the rear support 3 is provided with an adjustment mechanism 6 for adjusting the installation height of the slide rod 4. By adjusting the installation height of the slide rod 4 on the rear support 3, the tilt angle of the slide rod 4 is adjusted, thereby controlling the feeding speed of the connecting rod 9 and ensuring that the connecting rod 9 slides smoothly under different working conditions and achieves millimeter-level precise positioning. Furthermore, the adjustment mechanism can adjust the tilt angle of the slide rod 4 between 15° and 25°. In one embodiment, the rear support 3 includes two first columns 31 spaced apart on the base. Each first column 31 has an elongated hole 32 and a support protrusion 33. The elongated hole 32 is located above the support protrusion 33. The adjustment mechanism 6 includes a rear crossbeam 61 and two long bolts 62. Both ends of the rear crossbeam 61 are slidably disposed within the elongated holes 32 of the two first columns 31. The bottom ends of the two long bolts 62 are threadedly connected to the support protrusions 33 of the two first columns 31, and the top ends of the long bolts 62 contact the rear crossbeam 61. A sliding rod 4 is disposed on the rear crossbeam 61. By rotating the long bolts 62, the long bolts 62 push the rear crossbeam 61 upwards or downwards, causing the rear crossbeam 61 to move upwards or downwards along the elongated hole 32, thereby driving one end of the sliding rod 4 to move upwards or downwards, thus adjusting the tilt angle of the sliding rod 4.

[0028] In one embodiment, the front support 2 includes a second connecting plate 21 and two second columns 22, which are spaced apart on the base 1. The second connecting plate 21 is connected to the top of each of the two second columns 22. Multiple baffles 5 are connected at their bottom ends to mounting plates 7, which are connected to the middle of each of the two second columns 22. This arrangement facilitates the installation of the baffles 5. In another embodiment, both the first column 31 and the second column 22 are L-shaped columns. The two first columns 31 are arranged opposite each other on the base 1, and the two second columns 22 are also arranged opposite each other on the base 1.

[0029] In one embodiment, the high-efficiency automated feeding bin for motorcycle engine connecting rods of this invention further includes an oil receiving tray 8, which is positioned below multiple sliding rods 4. The oil receiving tray 8 can be placed on the base 1, or on the front support 2 and rear support 3, as long as it is positioned below the multiple sliding rods 4. During the sliding process of the connecting rod 9, the oil receiving tray 8 is responsible for collecting the oil dripping from the connecting rod 9, keeping the working environment clean.

[0030] In one embodiment, the base 1 includes a base plate 11 and a support frame 12 disposed at the bottom of the base plate 11. The base 1, with its base plate 11 and support frame 12, resembles a table structure, which can prevent the hopper from shaking during operation and ensure the positional accuracy of the connecting rod 9 when loading materials.

[0031] In one embodiment, the number of slide rods 4 is set to five.

[0032] 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. Therefore, 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 content of the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
