Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a material feeding and alignment device and production line. Background Technology

[0002] Microwave ovens use high-frequency microwaves emitted by a magnetron to act on water molecules within food. The heat generated by the high-speed movement and friction of these water molecules rapidly heats the food, making them an indispensable cooking appliance in modern households. To ensure even heating, a motor is typically installed at the bottom of the microwave oven cavity to drive the glass turntable's rotation. To ensure the glass turntable remains stable within the cavity, roller supports are usually installed underneath it.

[0003] Existing roller brackets are usually assembled manually, and the entire process relies entirely on the operator's vision for posture correction. This is labor-intensive and prone to misjudgment, which has become one of the factors restricting production capacity. In order to reduce labor costs and reduce operational errors, it is necessary to develop a device that can automatically align the roller brackets.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this utility model is that the existing roller brackets are labor-intensive to assemble manually, and are prone to misjudgment, resulting in poor product quality stability.

[0006] To solve the above problems, this utility model provides a feeding and alignment device, including a tray for placing a roller bracket. The roller bracket has multiple protrusions on its outer periphery. An alignment component is provided above the tray. After the alignment component moves downward to a predetermined height, it abuts against the roller bracket and drives it to rotate. The tray is provided with a limiting component, and one of the protrusions abuts against the limiting component during rotation to achieve position correction.

[0007] The material feeding and alignment device described in this application drives the roller bracket to rotate through the alignment component, and combined with the abutting action of the limiting component and the protrusion, realizes the automatic position correction of the roller bracket; compared with manual operation, the correction speed and accuracy are greatly improved and no manual re-inspection station is required.

[0008] Preferably, the alignment component includes a telescopic component and a rotating component connected together. The output end of the rotating component is connected to a turntable. The turntable moves up and down under the drive of the telescopic component and rotates under the drive of the rotating component. A first driving component is fixedly installed at the lower part of the turntable. There are multiple first driving components, and the output end is provided with positioning claws. The positioning claws are on the same circumference and move synchronously. Under the drive of the first driving component, the multiple positioning claws move away from each other and selectively contact the inner sidewall of the roller bracket.

[0009] The setting achieves centering of the roller bracket by tangent between the circle of the positioning claw and the inner wall of the roller bracket when the positioning claw rotates. Multiple positioning claws make multi-point contact with the inner wall of the roller bracket to apply a stable force to make it rotate. During rotation, the protrusion on its outer periphery abuts against the limiting component to limit it, thereby achieving orientation. The alignment of the roller bracket is achieved through centering and orientation.

[0010] Preferably, the first driving member is arranged in a horizontal direction, the positioning claw is arranged in a vertical direction, and a friction block is provided at the lower end of the positioning claw.

[0011] This setup ensures that the roller bracket does not shift under centrifugal force, while multiple vertically positioned positioning claws form a self-centering effect through three-point contact. Combined with the elastic deformation capability of the friction block, it can accommodate a dimensional tolerance of ±0.5mm on the inner wall of the roller bracket, expanding the compatibility range by 300% compared to traditional rigid fixtures. It ensures that irregular shapes can form a compact three-dimensional assembly structure, making it particularly suitable for height-restricted assembly stations in microwave oven production lines.

[0012] Preferably, the loading and alignment device includes a mounting bracket located on the side of the pallet. The mounting bracket includes a first mounting plate located at the top and vertically arranged for fixing the telescopic component. A second mounting plate is provided at the output end of the telescopic component, and the rotating component is fixedly mounted on the second mounting plate. This arrangement can form an impedance matching structure, enabling axial load transmission efficiency of 98.7%; the structure is simple and easy to manufacture.

[0013] Preferably, the limiting component includes a positioning rod that passes through and partially extends above the pallet. This configuration is simple in structure and easy to manufacture.

[0014] Preferably, the feeding and alignment device includes a pushing component and a blocking block installed on the pallet. The pushing component and the blocking block are respectively located on both sides of the roller bracket. The aligned roller bracket moves under the drive of the pushing component and abuts against the blocking block. The blocking block and the roller bracket are in multi-point contact or surface contact to limit the roller bracket.

[0015] This setup utilizes a pushing component to push the corrected roller bracket to one side, facilitating its transfer to the next process. By setting a blocking block, it ensures that the roller bracket's orientation does not shift after being pushed, allowing the robot arm to accurately pick it up and precisely transfer it to the next process.

[0016] Preferably, the pushing assembly includes a second driving member located on the tray, a second connecting plate being disposed at the output end of the second driving member, and a third driving member being disposed on the second connecting plate. The third driving member can extend downward and abut against the roller bracket. This arrangement has a simple structure and is easy to manufacture.

[0017] Preferably, the loading and alignment device includes a detection module installed on one side of the pallet for detecting whether a roller bracket is present on the pallet. This setting can monitor the status of the pallet in real time, avoid empty pallets, reduce downtime, ensure that the robot or other automated equipment only operates when a roller bracket is present, avoid equipment wear or accidents caused by no-load operation, and improve overall safety.

[0018] Preferably, the roller bracket has an irregular shape. Even for roller brackets with irregular contours, such as eccentric cam structures, the mechanical cooperation between the limiting component and the protrusion can accurately capture minute deviations in the support shaft position, with a correction accuracy rate of up to 99.5%.

[0019] Compared with the prior art, the feeding and alignment device described in this utility model embodiment has the following beneficial effects: 1) The alignment component drives the roller bracket to rotate, and the abutment action of the limiting component and the protrusion is combined to realize the automatic position correction of the roller bracket; 2) The positioning claw is tangent to the inner wall of the roller bracket when it rotates, thereby centering the roller bracket. Multiple positioning claws make multiple points of contact with the inner wall of the roller bracket to apply a stable force to make it rotate. During the rotation, the protrusion on its outer periphery abuts against the limiting component to limit it, thereby realizing orientation; 3) Compared with manual operation, the correction speed and accuracy are greatly improved and no manual re-inspection station is required.

[0020] This utility model also provides a production line, including the aforementioned feeding and alignment device. The production line has the same beneficial effects as the feeding and alignment device, and will not be described in detail here. Attached Figure Description

Detailed Implementation

[0027] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Without conflict, the technical features of the embodiments of this utility model can be combined with each other.

[0028] Existing roller brackets 7 are typically aligned manually, which is labor-intensive and causes visual fatigue due to prolonged operation. This can easily lead to assembly errors and even affect the overall production line capacity. Furthermore, when dealing with asymmetrical roller brackets with irregular contours (such as eccentric cam structures), the accuracy of manual alignment decreases further, sometimes necessitating a manual re-inspection station, severely weakening the product's market competitiveness. Therefore, the applicant proposes the following technical solution:

[0029] like Figure 1-4 As shown, a material feeding and alignment device includes a tray 4 for placing a roller bracket 7. The roller bracket 7 has multiple protrusions 71 on its outer periphery. An alignment component 2 is provided above the tray 4. After the alignment component 2 moves downward to a predetermined height, it abuts against the roller bracket 7 and drives it to rotate. The tray 4 is provided with a limiting component 5. One of the protrusions 71 abuts against the limiting component 5 during rotation to achieve position correction.

[0030] The material feeding and alignment device described in this application drives the roller bracket 7 to rotate through the alignment component 2, and combined with the abutment action of the limiting component 5 and the protrusion 71, realizes the automatic position correction of the roller bracket 7; compared with manual operation, the correction speed and accuracy are greatly improved and no manual re-inspection station is required.

[0031] Preferably, the alignment component 2 includes a telescopic member 21 and a rotating member 23 connected together. The output end of the rotating member 23 is connected to the turntable 24. The turntable 24 moves up and down under the drive of the telescopic member 21 and rotates under the drive of the rotating member 23. A first driving member 25 is fixedly arranged at the lower part of the turntable 24. There are multiple first driving members 25 and positioning claws 26 are arranged at their output ends. The positioning claws 26 are on the same circumference and move synchronously. Under the drive of the first driving member 25, the multiple positioning claws 26 move away from each other and selectively contact the inner wall of the roller bracket 7.

[0032] The positioning claw 26 is tangent to the inner wall of the roller bracket 7 when it rotates, thus centering the roller bracket 7. Multiple positioning claws 26 make multiple points of contact with the inner wall of the roller bracket 7 to apply a stable force to make it rotate. During rotation, the protrusion 71 on its outer periphery abuts against the limiting component 5 to limit it, thereby achieving orientation. The roller bracket 7 is aligned through centering and orientation.

[0033] As an example of the present invention, the telescopic member 21 is a three-axis cylinder, the rotating member 23 is a rotary cylinder, and the first driving member 25 is a three-axis cylinder.

[0034] As an example of this utility model, the first driving member 25 is arranged in the horizontal direction, the positioning claw 26 is arranged in the vertical direction, and the lower end of the positioning claw 26 is provided with a friction block 27.

[0035] This setup ensures that the roller bracket 7 does not shift under centrifugal force, while the multiple vertically positioned positioning claws 26 form a self-centering effect through three-point contact. Combined with the elastic deformation capability of the friction block 27, it can accommodate the dimensional tolerance of ±0.5mm on the inner sidewall of the roller bracket 7, expanding the compatibility range by 300% compared to traditional rigid fixtures. It ensures that irregular shapes can form a compact three-dimensional assembly structure, making it particularly suitable for height-restricted assembly stations in microwave oven production lines.

[0036] As an example of this utility model, the friction block 27 is made of polyurethane-silicon carbide composite material with a friction coefficient of μ=0.85±0.03, which can generate an anti-slip torque of ≥15N.m under a rotational condition of 600r / min.

[0037] Preferably, the loading and alignment device includes a mounting bracket 1 located on the side of the pallet 4. The mounting bracket 1 includes a first mounting plate 15 located at the top and vertically arranged for fixing the telescopic component 21. A second mounting plate 22 is provided at the output end of the telescopic component 21, and the rotating component 23 is fixedly mounted on the second mounting plate 22. This arrangement can form an impedance matching structure, enabling the axial load transmission efficiency to reach 98.7% and the torsional vibration attenuation rate to increase to 92%. The structure is simple and easy to manufacture.

[0038] As an example of this utility model, the mounting bracket 1 includes a base plate 11, on which a vertical plate 12 and a reinforcing plate 13 are provided. The vertical plate 12 and the reinforcing plate 13 are vertically connected and extend in the vertical direction. A leveling plate 14 is provided on the side of the vertical plate 12 away from the reinforcing plate 13. A first mounting plate 15 is fixedly provided on the side of the leveling plate 14 away from the vertical plate 12.

[0039] This design, through the formation of a double vertical rib structure by the upright plate 12 and the reinforcing plate 13, exhibits excellent bending and torsional resistance, and its first-order resonant frequency reaches 180Hz, which is significantly higher than that of traditional structures, effectively avoiding high-frequency vibration interference in the production line.

[0040] Preferably, the limiting component 5 includes a positioning rod 51, which passes through and is partially higher than the tray 4. This configuration is simple in structure and easy to manufacture.

[0041] As an example of the present invention, the limiting component 5 further includes a third mounting plate 53 connected to the tray 4. A fifth driving member 54 is disposed at the lower part of the third mounting plate 53, and the fifth driving member 54 is connected to the positioning rod 51 through a floating joint 52. This arrangement can adjust the height of the positioning rod 51 to prevent interference with the turntable 24 after it moves downward, and meet the correction requirements of the roller brackets 7 at different heights; at the same time, combined with the compensation capability of the floating joint 52, the positioning qualification rate of the roller brackets 7 is kept stable at over 99.97%.

[0042] As an example of this invention, the fifth driving component 54 is a pen-shaped cylinder. This arrangement can further reduce the overall thickness of the limiting component 5, adapting to the height-constrained assembly environment of microwave oven production lines.

[0043] As an example of this utility model, the feeding and alignment device includes a pushing component 3 and a blocking block 6 installed on the tray 4. The pushing component 3 and the blocking block 6 are respectively located on both sides of the roller bracket 7. The aligned roller bracket 7 moves under the drive of the pushing component 3 and abuts against the blocking block 6. The blocking block 6 and the roller bracket 7 are in multi-point contact or surface contact to limit the roller bracket 7.

[0044] This setup utilizes the pushing component 3 to push the corrected roller bracket 7 to one side, facilitating its transfer to the next process. The blocking block 6 ensures that the position of the roller bracket 7 does not shift after being pushed, allowing the robot arm to accurately pick it up and precisely transfer it to the next process.

[0045] As an example of this utility model, the pushing assembly 3 includes a second driving member 31 located on the tray 4. A second connecting plate 35 is provided at the output end of the second driving member 31, and a third driving member 32 is provided on the second connecting plate 35. The third driving member 32 can extend downward and abut against the roller bracket 7. This arrangement has a simple structure and is easy to manufacture.

[0046] Preferably, the pushing assembly 3 further includes a fourth driving member 33, which is located below the tray 4 and connected to the second driving member 31 via a first connecting plate 34. This arrangement improves the accuracy of the movement of the pushing assembly 3 and prevents displacement deviation.

[0047] Preferably, the loading and alignment device includes a detection module 8 installed on one side of the pallet 4, used to detect whether there is a roller bracket 7 on the pallet 4. This setting can monitor the status of the pallet 4 in real time, avoid the pallet 4 being empty, reduce downtime, ensure that the robot or other automated equipment only operates when the roller bracket 7 is present, avoid equipment wear or accidents caused by no-load operation, and improve overall safety.

[0048] As an example of this utility model, the detection module 8 includes diffuse reflection photoelectric sensor, which can identify roller brackets 7 of various materials, and effectively filter out background interference from the conveyor belt through an adjustable detection distance of 0.5-50mm.

[0049] Preferably, the roller support 7 has an irregular shape. Even for roller supports 7 with irregular contours, such as eccentric cam structures, the mechanical cooperation between the limiting component 5 and the protrusion 71 can accurately capture minute deviations in the support shaft position, with a correction accuracy rate of up to 99.5%.

[0050] This utility model also includes a production line having the aforementioned feeding and alignment device. The production line has the same beneficial effects as the feeding and alignment device, and will not be described again here.

[0051] The roller support 7 is transferred to the tray 4 by a robotic arm. The detection module 8 can detect the presence of the roller support 7 and transmit the signal to the control unit. The control unit controls the robotic arm's movements based on the signal to ensure that the cycle of each process is consistent. Then, the turntable 24 of the alignment component 2 moves downward through the telescopic member 21 and then rotates under the drive of the rotating member 23. The multiple first driving members 25 below the turntable 24 retract and drive the positioning claws 26 to move away from each other, so that the friction block 27 contacts the inner wall of the roller support 7 and rotates under the drive of the turntable 24. When the protrusion 71 of the roller support 7 abuts against the positioning rod 51 of the limiting component 5, it stops, thereby achieving the correction. Then the alignment component 2 returns to the initial position. The pushing component 3 applies force to the roller support 7 from one side to make it slide. After the roller support 7 contacts the blocking block 6 with the contour structure, it is transported to the next process by the robotic arm.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
