Detailed Embodiments

[0034] The following are specific embodiments of the present application. In combination with the accompanying drawings, the technical solutions of the present application will be further described. However, the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help comprehensively understand the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of known functions and configurations are omitted for clarity and conciseness.

[0035] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0036] The present application provides a detection and feeding device for pin components. The pin components can be electronic components such as resistors, capacitors, and gold-plated bases. The pin components have a head and pins. The detection and feeding device provided by the present application can prevent the pin components from being bent and damaged during the feeding process.

[0037] Referring to Figure 1 , the detection and feeding device includes a detection disk 10, a material grasping assembly 20, and a rotating seat 30. A detection opening 11 capable of placing pin components is provided on the detection disk 10. The material grasping assembly 20 includes a material grasping head 21 and a driving mechanism 22. The material grasping head 21 can grasp the head of the pin component. The driving mechanism 22 can drive the material grasping head 21 to act to place the pin component downward into the detection opening 11. Specifically, when the material grasping head 21 grasps the head of the pin component, its pins face downward. In one technical solution, the material grasping head 21 is a suction nozzle, and the head of the pin component is adsorbed by negative pressure. In another technical solution, the material grasping head 21 is a pneumatic chuck, and the head of the pin component is clamped pneumatically.

[0038] Continuing to refer to Figures 2 - 5 , a tapered hole 31 is provided on the rotating seat 30. The tapered hole 31 is located above the detection opening 11 and is aligned with the position of the detection opening 11. The tapered inner wall of the tapered hole 31 expands upward and converges downward. An open notch 311 is provided on one side of the tapered hole 31. The tapered hole 31 can guide the pins of the pin component W into the detection opening 11. The rotating seat 30 is installed in a rotatable manner and can rotate when the pins of the pin component enter the detection opening 11 downward so that the pins of the pin component pass through the notch 311 of the tapered hole 31 and are separated from the rotating seat 30.

[0039] When the driving mechanism 22 drives the material grabbing head 21 to move the pin component W downward into the detection port 11, the pin of the pin component W will first pass through the conical hole 31 on the rotating seat 30. When passing through the conical hole 31, due to the upward expansion and downward contraction of the conical inner wall of the conical hole 31, the pin of the pin component W will be limited and contracted by the conical inner wall of the conical hole 31 to the range of the detection port 11, which can prevent the pin of the pin component from deviating from the detection port and avoid bending and damage during the loading process. In addition, the rotating seat 30 is installed in a rotatable manner and an open notch 311 is provided on one side of the conical hole 31. When the pin of the pin component enters the detection port 11 downward, the rotating seat 30 can be moved away from the top of the detection port 11 by rotation and the pin of the pin component can be detached from the conical hole 31 through the notch 311 of the conical hole 31, so that the pin can smoothly enter the detection port 11 and the pin component W can be smoothly placed on the detection port 11.

[0040] exist Figure 3 In the structure shown, the detection port 11 is arranged at the edge of the detection disk 10, and the detection port 11 is an open structure, and the direction of its open notch is consistent with the notch direction of the tapered hole 31. Further, a plurality of detection ports 11 are arranged at intervals along the circumference of the detection disk 10.

[0041] In one embodiment of the present application, the inspection disk 10 is provided with a plurality of inspection ports 11 spaced apart along its circumference; and the inspection feeding device further comprises a second driving source 12, which can drive the inspection disk 10 to rotate so that the inspection ports 11 thereon move one by one to a set position; the gripping assembly 20 is used to place the pin components into the inspection ports 11 at the set position. Specifically, as the second driving source 12 drives the inspection disk 10 to rotate, the plurality of inspection ports 11 on the inspection disk 10 move one by one to a predetermined position below the rotating seat 30, and the driving mechanism 22 drives the gripping head 21 to place the pin components downwards into the plurality of inspection ports 11 one by one. Furthermore, the second driving source 12 can be a motor, specifically a stepping motor or a servo motor, which can stay at different angular positions according to program settings.

[0042] The material gripping head 21 is installed on the driving end of the driving mechanism 22. The driving mechanism 22 is used to drive the material gripping head 21 to act so as to place the pin element downward into the detection port 11. In the technical solution of the present application, the driving end of the driving mechanism 22 can at least move horizontally and vertically. By horizontal movement and vertical movement, the material gripping head 21 is moved to different positions, so that the material gripping head 21 can grip the pin element at position A, and then move it above the detection port 11 and place the pin element downward into the detection port 11. In a possible technical solution, the driving mechanism 22 has a horizontal movement component and a vertical movement component, so that the driving end can realize horizontal movement and vertical movement; further, the horizontal movement component can be a linearly arranged linear module, and the vertical movement component can be a vertically arranged linear module. In a possible technical solution, the driving mechanism 22 is a PPU manipulator. The PPU manipulator is a pure cam structure transfer manipulator. Under the action of a servo or stepper motor, an object can run along a predetermined trajectory and realize vertical and horizontal movements through guiding.

[0043] In an embodiment of the present application, an installation bracket 23 is provided on the driving end of the driving mechanism 22. A first driving source 24 is installed on the installation bracket 23. The first driving source 24 is connected to the material gripping head 21 and can drive the material gripping head 21 to rotate and adjust the angle. In some cases, the pin element needs to be detected at a specific placement angle. Further, the first driving source is linked and controlled with the camera recognition component, and the required rotation angle and rotation direction are detected and determined through the camera recognition component. Further, the first driving source is a stepper motor or a servo motor, and the rotation angle and rotation direction of the material gripping head can be accurately controlled.

[0044] Reference Figure 3 and Figure 4 , in an embodiment of the present application, during the process that the driving mechanism 22 drives the material gripping head 21 to act and place the pin element downward into the detection port 11, it drives the rotating seat 30 to rotate and separate from the pins of the pin element. The rotating seat 30 is also equipped with an elastic reset element 32. The elastic reset element 32 is used to drive the rotating seat 30 to rotate and reset to the initial position where the tapered hole 31 on it is aligned with the detection port 11.

[0045] Specifically, during the process that the material gripping head 21 moves downward and places the pin element downward into the detection port 11, the driving mechanism 22 comes into contact with the rotating seat 30, thereby forcing the rotating seat 30 to rotate and separate it from the pins of the pin element, so that the pins can smoothly enter the detection port 11, and the pin element W can be smoothly placed on the detection port 11. When the material gripping head 21 moves upward away from the detection port 11, the elastic reset element 32 can perform elastic reset, so that the rotating seat 30 rotates and resets to the initial position where the tapered hole 31 on it is aligned with the detection port 11. In a specific technical solution of the present application, the elastic reset element is a spring. In Figure 4In the described structure, the driving mechanism 22 drives the rotating seat 30 to rotate counterclockwise, and the elastic reset element applies a reset elastic force for clockwise rotation to the rotating seat 30.

[0046] Further, a driving member 25 is provided on the driving end of the driving mechanism 22, and a roller 251 is provided on the driving member 25; when the driving end of the driving mechanism 22 moves downward, the roller 251 presses downward against the rotating seat 30 and forces it to rotate and separate from the lead of the lead component. Figure 4 In the shown structure, the driving member 25 is connected to the mounting bracket 23, and the rotating seat 30 is mounted on the fixed structure. When the driving member 25 moves downward, the rotating seat 30 will rotate and yield, separating from the lead of the lead component.

[0047] Further, an adjusting screw 33 is provided on the mounting bracket of the rotating seat 30, and the adjusting screw 33 is used to adjust the initial position of the rotating seat 30. Figure 4 In the shown structure, the elastic reset element applies an elastic force for clockwise rotation to the rotating seat 30, and the adjusting screw 33 applies a limit for clockwise rotation. The adjusting screw 33 can adjust the limit position by screwing.

[0048] Refer to Figure 6 , in an embodiment of the present application, the detection and feeding device further includes a vibrating bowl 40, a vibrating feeder 50, and a receiving component 60; the vibrating bowl 40 is used to output lead components in sequence; the vibrating feeder 50 has a track 51 and a vibration source 52; the track 51 is connected to the discharge end of the vibrating bowl 40 to receive the lead components output from the vibrating bowl 40 one by one; the vibration source 52 acts on the track 51 to move the lead components on the track 51 forward; the receiving component 60 includes a receiving frame 61 and a third driving source 62, and the third driving source 62 can drive the receiving frame 61 to move between a first position and a second position; when the receiving frame 61 is in the first position, the receiving frame 61 is joined with the end of the track 51 to receive the lead components output from the track 51; when the receiving frame 61 is in the second position, the driving mechanism 22 drives the gripper head 21 to grasp the lead components on the receiving frame 61.

[0049] Specifically, the vibrating bowl is an auxiliary feeding device for an automatic assembly or automatic processing machine, which can automatically and orderly orient and arrange disordered workpieces neatly and accurately convey them to the next process through vibration. The track 51 is connected to the discharge end of the vibrating bowl 40 and can receive the lead components output from the vibrating bowl 40 one by one. Driven by the vibration source 52, the lead components on the track 51 can continuously move forward along the track. It should be understood that the vibrating feeder is used for a linear feeder, and its track can be set to be linear. A common linear feeder consists of three parts, including a linear track, an electromagnet, and a spring piece; by connecting the electromagnet to 220V alternating current to make the electromagnet vibrate, the electromagnet drives the linear track to move through the spring piece, so as to achieve the purpose of linear feeding.

[0050] Specifically, the third driving source 62 is an electric driving source or a pneumatic driving source, which can drive the receiving rack 61 to move between a first position and a second position. At the first position, the receiving rack 61 is joined with the end of the track 51 to receive the pin components output from the track 51. When the receiving rack 61 is at the second position, the driving mechanism 22 drives the material grabbing head 21 to grab the pin components on the receiving rack 61. The second position is the loading position, and the receiving rack 61 can sequentially convey the pin components output from the track 51 to the loading position.

[0052] Specifically, the detection device can be provided with multiple image acquisition units to respectively acquire images of the pin components from multiple angles, and the image recognition unit uploads the acquired images to the image recognition unit for recognition. The image processing unit includes an image processor, which can perform real-time processing on the graphics acquired by the image acquisition unit, and determine whether the pin components are defective through image processing and analysis.

The material grabbing assembly includes a material grabbing head and a driving mechanism.

Above the detection port, there is a rotating seat with a tapered hole, and the tapered hole is aligned with the position of the detection port, which is used to guide the pins of the pin component into the detection port; on one side of the tapered hole, there is an open notch, and the rotating seat is installed in a rotatable manner and can rotate when the pins of the pin component enter the detection port downward, so that the pins of the pin component pass through the notch of the tapered hole and are separated from the rotating seat.
