Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, and in particular to a hardware feeding mechanism. Background Technology

[0002] In the manufacturing and core component assembly of unmanned aerial vehicles (UAVs), L-shaped metal connectors are a type of critical structural component with extremely high application frequency. They are widely installed in core areas such as fuselage frame joints, wing-to-fuselage connection nodes, and battery compartment fixing mechanisms. Their main function is to achieve precise positioning and stable connection between different components, directly affecting the overall structural stability, load-bearing capacity, and flight safety of the UAV. These connectors are usually made of high-strength alloy materials. Currently, most manufacturers still rely on manual operation for the loading of L-shaped metal connectors. Operators need to place batches of L-shaped connectors one by one into designated slots in a special fixture at the loading station on the assembly line. Then, an automated robotic arm precisely picks up the connectors from the fixture according to a preset program and transports them to the subsequent automated assembly process to complete the bolting or welding operations with other components.

[0003] However, because the long and short sides of the L-shaped hardware connector are not significantly different in appearance, operators are prone to misplacing the long and short sides of the connector due to visual fatigue and lack of concentration during long periods of repetitive work. This can disrupt the assembly process, or even result in incorrectly assembled products and product defects. Therefore, it is necessary to develop a hardware feeding mechanism to solve these problems. Utility Model Content

If the long and short sides of the hardware parts are reversed or not placed in the correct position, the second proximity sensor will not be able to detect the long side of the hardware parts, but will still detect the abnormality. After all sensors detect no abnormalities, the movable carrier plate is controlled by an operation button to move to the rear end of the worktable, and the robotic arm picks up the hardware parts and transports them to the subsequent assembly process. The advantage of this design is that it can position hardware components, improving the efficiency of hardware placement. At the same time, it can detect whether hardware components are missing, reversed, or properly placed, ensuring that all hardware components are placed correctly and improving the product qualification rate.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1 to 3 As shown, a hardware parts loading mechanism includes a mounting base 1, a worktable 2, a Y-axis drive assembly 3, a movable carrier plate 4, a placement fixture 5, and an operation button 6. The worktable 2 is fixed above the mounting base 1, the Y-axis drive assembly 3 is fixed above the worktable 2, the movable carrier plate 4 is fixed to the power output end of the Y-axis drive assembly 3, the operation button 6 is fixed to the front side of the worktable 2 and is signal-connected to the Y-axis drive assembly 3, and the placement fixture 5 is fixed on the worktable 2. Multiple placement fixtures are provided, and each placement fixture 5 includes an adjusting base 51, a support block 52, a first proximity sensor 53, and a second proximity sensor 54. The adjusting base 51 is fixed above the movable carrier plate 4. The lower end of the support block 52 is fixed to the upper end of the adjusting base 51. The upper end of the support block 52 is provided with a mounting groove 521 and a positioning post 522. A vertical positioning surface 523 is provided on one side of the support block 52. The mounting groove 521 penetrates the vertical positioning surface 523. Two sets of positioning posts 522 are provided and correspond to the left and right sides of the mounting groove 521 respectively. The lower side of the support block 52 is provided with a mounting hole 524, which penetrates the vertical positioning surface 523. The first proximity sensor 53 and the second proximity sensor 54 are fixed in the mounting groove 521 and the mounting hole 524 respectively. The sensing ends of the first proximity sensor 53 and the second proximity sensor 54 are both corresponding to the vertical positioning surface 523.

[0021] The hardware loading mechanism of this design involves manually placing hardware parts onto the placement fixture 5. Before placement, the Y-axis drive assembly 3 is controlled by operating button 6 to move the movable carrier plate 4 to the front of the worktable 2. Then, the hardware parts are manually placed. The short side of the L-shaped hardware part is placed on the upper surface of the placement fixture 5, and the positioning pin 522 is inserted into the positioning hole of the short side. The long side is then pressed against the vertical positioning surface 523. The first proximity sensor 53 and the second proximity sensor 54 detect the upper and lower sides of the long side of the hardware part, respectively. Sensor 53 is used to detect whether the hardware parts are placed, and the second proximity sensor 54 is used to detect whether the hardware parts are placed in the correct direction and in the correct position. If a hardware part is missing, the first proximity sensor 53 will detect the abnormality. If the long and short sides of the hardware part are reversed or not placed in the correct position, the second proximity sensor 54 will not be able to detect the long side of the hardware part, and will also detect the abnormality. When all sensors detect no abnormalities, the movable carrier plate 4 is moved to the rear end of the worktable 2 by operating button 6, and the robot arm picks up the hardware part and transports it to the subsequent assembly process. The advantage of this design is that it can position the hardware parts, improve the placement efficiency of the hardware parts, and at the same time, it can detect whether the hardware parts are missing, reversed, or not placed in the correct position, to ensure that all hardware parts are placed correctly and improve the product qualification rate.

[0022] The Y-axis drive assembly 3 adopts a linear motor module, which has the advantages of high precision, high stability and high efficiency.

[0023] The movable carrier plate 4 is provided with hand-held through holes 41 on both the left and right sides, and multiple sets of placement fixtures 5 are respectively provided on the front and rear sides of the movable carrier plate 4.

[0024] The movable carrier plate 4 is easily moved through the hand-held through hole 41, which facilitates the disassembly and installation of the movable carrier plate 4 on the power output end of the Y-axis drive assembly 3.

[0025] The adjusting base 51 includes a connecting base plate 511, a connecting middle plate 512, a connecting top plate 513, a first L-shaped frame 514, a first connecting rod 515, an X-axis rotating rod 516, a second L-shaped frame 517, a second connecting rod 518, and a Y-axis rotating rod 519. The lower end of the connecting base plate 511 is fixed to the movable carrier plate 4. The lower end of the connecting middle plate 512 is slidably connected to the upper end of the connecting base plate 511 and can slide along the X-axis direction. The lower end of the connecting top plate 513 is slidably connected to the upper end of the connecting middle plate 512 and can slide along the Y-axis direction. Support block 5... 2. Fixed to the upper end of the connecting top plate 513, the first L-shaped frame 514 and the first connecting rod 515 are respectively fixed to the connecting bottom plate 511 and the connecting middle plate 512. The middle part of the X-axis rotating rod 516 is threaded to the first L-shaped frame 514 and the end is rotatably mounted on the first connecting rod 515. The second L-shaped frame 517 and the second connecting rod 518 are respectively fixed to the connecting middle plate 512 and the connecting top plate 513. The middle part of the Y-axis rotating rod 519 is threaded to the second L-shaped frame 517 and the end is rotatably mounted on the second connecting rod 518.

[0026] By rotating the X-axis rotary rod 516, the relative positions of the first L-shaped frame 514 and the first connecting rod 515 change. At the same time, the connecting middle plate 512 slides on the connecting base plate 511 along the X-axis direction, thereby adjusting the position of the support block 52 in the X-axis direction. By rotating the Y-axis rotary rod 519, the relative positions of the second L-shaped frame 517 and the second connecting rod 518 change. At the same time, the connecting top plate 513 slides on the connecting middle plate 512 along the Y-axis direction, thereby adjusting the position of the support block 52 in the Y-axis direction. This allows for adjustments to accommodate the placement of hardware components for different product models.

[0027] The operation buttons 6 include a forward button 61 and a backward button 62, which are fixed to the left and right sides of the front end of the worktable 2, respectively. Both the forward button 61 and the backward button 62 are connected to the Y-axis drive assembly 3 via signals. The forward button 61 and the backward button 62 control the forward and backward movement of the movable carrier plate 4, respectively.

[0028] This design also includes a loading box 7, which is fixed on the workbench 2 and corresponds to the area between the forward button 61 and the reverse button 62. The loading box 7 is used to hold the hardware parts to be loaded, making it convenient for operators to pick up the hardware parts.

[0029] This design also includes a safety light curtain 8, which is fixed on the worktable 2 and corresponds to the Y-axis drive assembly 3 and the operation button 6. When the safety light curtain 8 detects an object, the movable carrier plate 4 will not move, thereby improving the safety of operation.

[0030] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
