Detailed Embodiments
[0032] 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, but the present application is not limited to these embodiments. In the following description, providing specific details such as specific configurations and components is 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 here without departing from the scope and spirit of the present application. In addition, descriptions of known functions and structures are omitted for clarity and conciseness.
[0033] It should be noted that, without conflict, the implementation manners and features in the implementation manners of the present application can be combined with each other.
[0034] The present application provides a loading device for pin components. Refer to Figure 7 , the pin component W can be an electronic component such as a resistor, a capacitor, a gold-plated base, etc. The pin component has a head and pins. When loading, the present application can prevent the pins of the pin component from deviating from the loading hole through the guidance of the conical hole, and avoid bending and damage during the loading process.
[0035] Refer to Figure 1 , the loading device for pin components includes: a bracket 10, a material-gripping assembly 20, and a limit guiding mechanism 30. Among them, the material-gripping assembly 20 includes a material-gripping head 21 and a driving mechanism 22; the material-gripping head 21 can grip the head of the pin component W; the driving mechanism 22 can drive the material-gripping head 21 to act to load the pin component downward into the loading hole 41 of the material plate 40. The limit guiding mechanism 30 includes a first limit frame 31, a second limit frame 32, and a driving element; a first semi-conical hole 311 is provided on the first limit frame 31, and a second semi-conical hole 321 is provided on the second limit frame 32; the driving element can drive the first limit frame 31 and the second limit frame 32 to slide horizontally and approach each other so that the first semi-conical hole 311 and the second semi-conical hole 321 are combined together to form a complete conical hole 35; the conical inner wall of the formed conical hole expands upward and converges downward to guide the pins of the pin component into the loading hole on the lower material plate; when the pin component is loaded downward into the loading hole of the material plate, the first limit frame 31 and the second limit frame 32 slide horizontally and retreat backward to move away from each other.
[0036] When the material-gripping head 21 grips the head of the pin component, its pins face downward and are placed into the conical hole 35. In a specific technical solution, the material-gripping head is a suction nozzle, and the head of the pin component is adsorbed by negative pressure. In another specific technical solution, the material-gripping head is a pneumatic chuck, and the head of the pin component is clamped pneumatically.
[0037] Refer to Figures 2 - 6, a first limiting frame 31 is provided with a first semi-conical hole 311, and a second limiting frame 32 is provided with a second semi-conical hole 321. Under the action of a driving element, the first limiting frame 31 and the second limiting frame 32 slide horizontally and approach each other so that the first semi-conical hole 311 and the second semi-conical hole 321 are combined together to form a complete conical hole 35. During the process that the driving mechanism 22 drives the material grabbing head 21 to act and load the pin element downward into the loading hole 41 of the material plate 40, the pins of the pin element will first pass through the conical hole 35. When passing through the conical hole 35, due to the upward expansion and downward convergence of the conical inner wall of the conical hole, the pins of the pin element will be limited and converged by the conical inner wall of the conical hole 35 within the range of the loading hole 41, which can prevent the pins of the pin element from deviating from the loading hole 41 and avoid bending and damage during the loading process. In addition, when the pin element is loaded downward into the loading hole of the material plate, the first limiting frame 31 and the second limiting frame 32 slide horizontally and retreat backward to move away from each other, so that the material grabbing head 21 can pass through the gap space between the first limiting frame 31 and the second limiting frame 32 and place the pin element into the lower loading hole.
[0038] In addition, it should be understood that a plurality of loading holes 41 can be arranged and arranged on the material plate 40, and the loading device loads materials at a set loading position. After one loading, the material plate 40 can be moved to make the next loading hole 41 move to the set loading position for loading. In this way, each time loading is performed, a movement is carried out. Through multiple movements, all the loading holes on the material plate 40 can be loaded with pin elements.
[0039] Furthermore, the material grabbing head 21 is installed on the driving end of the driving mechanism 22, and the driving mechanism 22 is used to drive the material grabbing head 21 to act to load the pin element downward into the loading hole 41 of the material plate 40. In the technical solution of the present application, the driving end of the driving mechanism 22 can at least move horizontally and vertically. By moving horizontally and vertically, the material grabbing head 21 is moved to different positions, so that the material grabbing head 21 can grab the pin element at position A, and then move it to the set loading position above the material plate 40 and put the pin element downward into the loading hole. 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; furthermore, the horizontal movement component can be a horizontally arranged linear module, and the vertical movement component can be a vertically arranged linear module. In a possible technical solution, the driving mechanism 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 move along a predetermined trajectory and realize vertical and horizontal movements through guidance.
[0040] In an embodiment of the present application, both the first limiting frame 31 and the second limiting frame 32 are installed on a fixed guide rail 11; the driving element is an elastic element, and the elastic element is used to drive the first limiting frame 31 and the second limiting frame 32 to slide horizontally and approach each other along the guide rail 11 so that the first semi-conical hole 311 and the second semi-conical hole 321 are joined together to form a complete conical hole 35. Specifically, a guide rail 11 is arranged on the bracket 10 for installing the first limiting frame 31 and the second limiting frame 32 and guiding the first limiting frame 31 and the second limiting frame 32 to slide laterally. The elastic element can be a spring. Under the action of the spring, the first limiting frame 31 and the second limiting frame 32 approach each other, so that the first semi-conical hole 311 and the second semi-conical hole 321 are joined together to form a complete conical hole 35.
[0041] Further, the elastic element includes a first elastic element 33 and a second elastic element 34. Among them, the first elastic element 33 acts on the first limiting frame 31, and the second elastic element 34 acts on the second limiting frame 32. In Figure 3 the structure shown, the first elastic element 33 applies an elastic force to the first limiting frame 31 to make it approach the second limiting frame 32, and the second elastic element 34 applies an elastic force to the second limiting frame 32 to make it approach the first limiting frame 31. Thus, under the action of the first elastic element 33 and the second elastic element 34, the first limiting frame 31 and the second limiting frame 32 approach each other, and the first semi-conical hole 311 and the second semi-conical hole 321 are joined together to form a complete conical hole 35.
[0042] It should be understood that the elastic element includes a first elastic element 33 and a second elastic element 34, acts on the first limiting frame 31 and the second limiting frame 32 and can undergo elastic deformation. Therefore, when the first limiting frame 31 and the second limiting frame 32 move away from each other, the first elastic element 33 and the second elastic element 34 can undergo adaptive elastic deformation and generate a restoring elastic force that makes the first limiting frame 31 and the second limiting frame 32 approach each other.
[0043] Further, fixed first and second limit blocks 12 and 13 are respectively provided on the two outer sides of the first limit frame 31 and the second limit frame 32; moreover, the first limit block 12 is located on one side of the first limit frame 31, and the second limit frame 32 is located on one side of the second limit block 13; the first elastic element 33 is located between the first limit block 12 and the first limit frame 31, and the second elastic element 34 is located between the second limit block 13 and the second limit frame 32. Specifically, when the first limit frame 31 and the second limit frame 32 move away from each other, the first limit frame 31 moves towards the first limit block 12, the distance between the first limit frame 31 and the first limit block 12 decreases, and the first elastic element 33 undergoes compressive deformation; the second limit frame 32 moves towards the second limit block 13, the distance between the second limit block 13 and the second limit frame 32 decreases, and the second elastic element 34 undergoes compressive deformation. Further, the first elastic element 33 is a spring and is sleeved on the first guide rod 313; the second elastic element 34 is a spring and is sleeved on the second guide rod 323.
[0044] In an embodiment of the present application, during the process that the driving mechanism 22 drives the material grasping head 21 to act to downwardly load the pin element into the loading hole of the material plate, the driving mechanism drives the first limit frame 31 and the second limit frame 32 to horizontally slide backward along the guide rail 11 to move away from each other. Specifically, during the loading process, when the driving end of the driving mechanism 22 drives the material grasping head 21 to move downward, the structure of the driving end comes into contact with the first limit frame 31 and the second limit frame 32, and under the interaction, the first limit frame 31 and the second limit frame 32 overcome the elastic force of the elastic element and move backward to move away from each other.
[0045] Continue to refer to Figure 4 , a V-shaped driving member 23 is provided on the driving mechanism 22; a first roller 312 is provided on the side of the first limit frame 31 close to the second limit frame 32; a second roller 322 is provided on the side of the second limit frame 32 close to the first limit frame 31. During the process that the driving mechanism 22 drives the material grasping head 21 to act to downwardly load the pin element into the loading hole of the material plate, the V-shaped driving member 23 is inserted between the first roller 312 and the second roller 322, and forces the first limit frame 31 and the second limit frame 32 to move backward to move away from each other.
[0046] In Figure 4In the structure shown, during the loading process, when the driving end of the driving mechanism 22 drives the material grabbing head 21 to move downward, the V-shaped driving member 23 moves downward and inserts between the first roller 312 and the second roller 322, and the inclined surfaces on both sides thereof are respectively in contact with the first roller 312 and the second roller 322 on both sides. As the V-shaped driving member 23 continues to move downward, the inclined surfaces on both sides of the V-shaped driving member 23 can respectively drive the first limiting frame 31 and the second limiting frame 32 to retreat backward and move away from each other. Moreover, the first semi-conical hole 311 and the second semi-conical hole 321 are separated, thereby forming a clearance space for the material grabbing head 21 to pass through. Further, during the upward movement of the material grabbing head 21 after placing the pin element into the loading hole, the V-shaped driving member 23 moves upward accordingly. Under the action of the elastic element, the first limiting frame 31 and the second limiting frame 32 move closer to each other again, so that the first semi-conical hole 311 and the second semi-conical hole 321 are joined together again to form a complete conical hole 35 for the next loading.
[0047] In the embodiment of the present application, during the process of the driving mechanism driving the material grabbing head to act and load the pin element of the pin element downward into the loading hole of the material plate, the pins of the pin element will first pass through the conical hole. When passing through the conical hole, due to the upward expansion and downward convergence of the conical inner wall of the conical hole, the pins of the pin element will be limited and converged by the conical inner wall of the conical hole within the range of the loading hole, which can prevent the pins of the pin element from deviating from the loading hole and avoid bending and damage during the loading process. In addition, when the pin element is loaded downward into the loading hole of the material plate, the first limiting frame and the second limiting frame slide horizontally backward and retreat away from each other, so that the material grabbing head can pass through the clearance space between the first limiting frame and the second limiting frame and place the pin element into the lower loading hole.
[0048] The embodiment of the present application further provides a detection device, including: a detection component and the loading device provided in the previous part; the detection component is used to detect the pin element; the loading device is used to load the pin element after being detected by the detection component into the loading hole of the material plate. In the embodiment of the present application, the detection component includes an image acquisition unit and an image recognition unit. Among them, the image acquisition unit is used to acquire an image of the pin element, and the image recognition unit is connected to the image acquisition unit to perform recognition and detection on the image acquired by the image acquisition unit. After the detection is completed, the loading device sequentially transfers the pin elements on the detection table into the loading holes of the material plate. For the related technical means and technical effects, refer to the description of the loading device in the previous part, which will not be elaborated here.
