Description

Technical Field

[0001] This utility model belongs to the field of electronic component technology, and specifically relates to an electronic component picking and placing device. Background Technology

[0002] Electronic components, as the basic building blocks of modern electronic systems, encompass a variety of devices such as resistors, capacitors, inductors, diodes, transistors, integrated circuits, connectors, and sensors. They enable the functionality and intelligence of circuits by regulating, transmitting, processing, and feeding back current, voltage, signals, and energy. Their performance stability, material properties, packaging forms, and process precision directly determine the reliability and adaptability of the entire device. They are widely used in consumer electronics, communication equipment, industrial control, automotive electronics, energy equipment, and aerospace, and are key basic components supporting the development of information technology, intelligent manufacturing, and high-end manufacturing technologies.

[0003] Traditional electronic pick-and-place components typically use a control board paired with an air pump to form an adsorption execution system. This requires users to perform complex programming and parameter settings for the air pump start-stop logic, adsorption timing, pressure threshold, anomaly handling, and linkage with the motion axis before use. This makes the overall debugging process not only dependent on strong programming skills and electrical control experience, but also prone to problems such as unstable adsorption, response delays, or execution errors when first getting started due to cumbersome instruction configuration, high timing coupling, and strong parameter correlation. This significantly increases the barrier to entry and prolongs the equipment implementation cycle. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electronic component pick-and-place device.

[0005] To achieve the above objectives, this utility model provides an electronic component loading and unloading device, including a gantry frame and an adsorption tube. The adsorption tube is fixed to a movable part of the gantry frame, which drives the adsorption tube to move laterally and vertically. An air pipe is also included. The movable part of the gantry frame is a second slider for vertical movement. When the second slider moves downward, a piston rod slidably mounted inside the air pipe moves downward. An air seat fixed in the middle of the air pipe is connected to the adsorption tube via a transmission pipe. When the piston rod moves downward to the air seat position, the air pipe and piston rod together form a negative pressure air chamber communicating with the air seat. At this time, the adsorption tube performs an air suction action to pick up the electronic component. After the electronic component is laterally displaced by the gantry frame, the piston rod continues to move downward to the electronic component mounting position. The negative pressure air chamber of the air pipe communicates with the outside through air holes opened on the outer wall of the air pipe, thereby releasing the electronic component. In the above technical solution, the gantry frame further includes a support frame, the two support legs of the support frame are of different lengths, and the shorter support leg is located near the electronic component area.

[0006] In the above technical solution, the horizontal motor fixed on the upper part of the support frame is fixedly connected to one end of the first lead screw rotatably mounted on the upper part of the support frame, and the first lead screw is screwed into the first slider slidably mounted on the upper part of the support frame. In the above technical solution, a vertical motor is further fixedly installed on the upper part of the support plate on one side of the first slider, and one end of the second lead screw rotatably installed on the support plate is fixedly connected to the output end of the vertical motor. In the above technical solution, the adsorption tube is further screwed to the lower part of the second slider and communicates with the transmission tube through an air passage opened inside the second slider. In the above technical solution, further, a linkage rod is fixedly connected to the output end of the piston rod, and a first baffle and a second baffle are fixedly connected to the linkage rod. The first baffle is located below the second baffle, and the second slider is between the first baffle and the second baffle. When the second slider moves down and contacts and presses the first baffle, the one-way valve fixed on the upper part of the air pipe is in an open circuit state. At this time, the piston rod moves down to form the negative pressure air chamber. When the second slider moves up and contacts and lifts the second baffle, it drives the piston rod to move up and reset, and the one-way valve is in a passage exhaust pressure stabilization state.

[0007] Compared with the prior art, this utility model has the following advantages: It utilizes a gantry frame to achieve synchronous horizontal and vertical movement of the adsorption tube and the air tube; when the second slider moves downward, it drives the entire air tube to descend, causing the internally slidably mounted piston rod to first move to the position corresponding to the air seat, forming a closed negative pressure air chamber between the air seat and the piston rod. The negative pressure acts on the adsorption tube through the transmission tube to complete the adsorption action of the electronic component; subsequently, the gantry frame drive assembly moves the adsorption tube along a predetermined path to the installation position and continues to push the piston rod downward, causing the negative pressure air chamber to move further downward until it connects with the air pores on the outer wall of the air tube, thereby rapidly restoring the original negative pressure and releasing the adsorption force, achieving reliable release of the electronic component at the target position; Throughout the entire pick-up and drop-off process, the air pressure changes generated by the piston movement are used to drive the adsorption and desorption actions. No additional programming is required to control the air pump, which significantly reduces the debugging difficulty and improves the automated pick-up and drop-off efficiency of electronic components.

Detailed Implementation To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0010] like Figures 1-4 An electronic component loading and unloading device is shown, including a gantry frame and an adsorption tube 18. The adsorption tube 18 is fixed on the movable part of the gantry frame, which drives the adsorption tube 18 to move laterally and vertically. An air pipe 9 is also included. The movable part of the gantry frame is a second slider 8 for vertical movement. When the second slider 8 moves downward, a piston rod 17 slidably installed inside the air pipe 9 moves downward. An air seat 15 fixed in the middle of the air pipe 9 communicates with the adsorption tube 18 through a transmission pipe 13. When the piston rod 17 moves downward to the position of the air seat 15, the air pipe 9 and piston rod 17 form a negative pressure air chamber communicating with the air seat 15. At this time, the adsorption tube 18 performs an air suction action to pick up the electronic component. After the electronic component is laterally displaced by the gantry frame, the piston rod 17 continues to move downward to the electronic component mounting position. The negative pressure air chamber of the air pipe 9 communicates with the outside through an air hole 16 opened on the outer wall of the air pipe 9, thereby releasing the electronic component. The above-mentioned electronic component loading and unloading device utilizes a gantry frame to achieve synchronous horizontal and vertical movement of the adsorption tube 18 and the air tube 9. When the second slider 8 moves down, it causes the air tube 9 to descend as a whole, so that the internally slidably mounted piston rod 17 first moves to the position corresponding to the air seat 15, forming a closed negative pressure air chamber between the air seat 15 and the piston rod 17. The negative pressure acts on the adsorption tube 18 through the transmission tube 13 to complete the adsorption action of the electronic components. Subsequently, the gantry drive assembly moves the adsorption tube 18 along the predetermined path to the installation position and continues to push the piston rod 17 downward, causing the negative pressure air chamber to move further down until it connects with the air hole 16 on the outer wall of the air pipe 9, thereby quickly restoring the original negative pressure and releasing the adsorption force, so as to reliably release the electronic components at the target position.

[0011] In this embodiment, the gantry includes a support frame 1. The two support legs of the support frame 1 are of different lengths. The support leg with the shorter support leg is located near the electronic component area. A horizontal motor 2 fixed to the upper part of the support frame 1 is fixedly connected to one end of a first lead screw 3 rotatably mounted on the upper part of the support frame 1. The first lead screw 3 is screwed into the first slider 4 slidably mounted on the upper part of the support frame 1. A vertical motor 6 is fixedly mounted on the upper part of a support plate 5 on one side of the first slider 4. One end of a second lead screw 7 rotatably mounted on the support plate 5 is fixedly connected to the output end of the vertical motor 6. An adsorption tube 18 is screwed into the lower part of the second slider 8 and communicates with the transmission tube 13 through an air passage opened inside the second slider 8. The support legs with different structural heights form a low working end close to the electronic components, so that the horizontal motor 2 fixed on the upper part of the support frame 1 drives the first lead screw 3 to rotate and drive the first slider 4 screwed to it to move precisely laterally along the support frame 1. The vertical motor 6 installed on the support plate 5 on the side of the first slider 4 further drives the second lead screw 7, which is fixedly connected to its output end, to rotate synchronously. This allows the second slider 8, which is screwed to the second lead screw 7, to move vertically in a controllable manner. The adsorption tube 18 is directly screwed to the lower part of the second slider 8 and forms an airflow channel inside the second slider 8 that communicates with the transmission tube 13. This allows the adsorption tube 18 to perform precise three-dimensional spatial positioning and pick-and-place actions under the bidirectional coordinated drive of the horizontal motor 2 and the vertical motor 6. The horizontal movement is used to realize cross-area movement between the electronic component area and the installation area, and the vertical movement is used to realize precise height control during adsorption, handling and release. The structural design with varying lengths of the supporting legs ensures that the adsorption end can get closer to the electronic component placement surface, thereby shortening the pick-and-place stroke, improving positioning accuracy, and reducing energy consumption. Finally, through the linkage mechanism of motor drive, lead screw guidance, slider movement, and adsorption tube 18, the entire electronic component pick-and-place process has the characteristics of path controllability, stable action, fast response, and high adaptability.

[0012] In this embodiment, a linkage rod 10 is fixedly connected to the output end of the piston rod 17. A first baffle 11 and a second baffle 12 are fixedly connected to the linkage rod 10. The first baffle 11 is located below the second baffle 12, and the second slider 8 is between the first baffle 11 and the second baffle 12. When the second slider 8 moves down and contacts and presses the first baffle 11, the one-way valve 14 fixed on the upper part of the air pipe 9 is in an open circuit state. At this time, the piston rod 17 moves down to form a negative pressure air chamber. When the second slider 8 moves up and contacts and lifts the second baffle 12, it drives the piston rod 17 to move up and reset. The one-way valve 14 is in a passage exhaust pressure stabilization state.

[0013] By fixing the linkage rod 10 to the output end of the piston rod 17 and sequentially setting the lower first baffle 11 and the upper second baffle 12 on it, the second slider 8 is always positioned between the two baffles and triggers different air pressure control states during the vertical reciprocating motion: When the second slider 8 moves downward and first contacts and presses the first baffle 11, the piston rod 17 is pushed downward synchronously, causing the one-way valve 14 fixed on the upper part of the air pipe 9 to enter the circuit break state. The air passage forms a closed cavity and forms a negative pressure air chamber with the stroke of the piston rod 17, which is used to drive the adsorption end to generate adsorption capacity. When the second slider 8 moves upward and contacts and lifts the second baffle 12, it drives the piston rod 17 to move upward in the opposite direction to the initial position, so that the one-way valve 14 returns to the open state and discharges the gas inside the air chamber, realizing the pressure stabilization and repressurization action. Thus, the dual functions of adsorption and release are completed in one continuous reciprocating stroke, and the negative pressure establishment and release process is stable and controllable, without relying on external programming or independent air pump drive.

[0014] Working principle: The gantry frame is used to realize the synchronous horizontal and vertical movement of the adsorption tube 18 and the air tube 9. When the second slider 8 moves down, it drives the air tube 9 to descend as a whole, so that the internally sliding piston rod 17 first moves to the position corresponding to the air seat 15, forming a closed negative pressure air chamber between the air seat 15 and the piston rod 17. The negative pressure acts on the adsorption tube 18 through the transmission tube 13 to complete the adsorption action of the electronic component. Then the gantry frame drive assembly moves the adsorption tube 18 along the predetermined path to the installation position and continues to push the piston rod 17 downward, so that the negative pressure air chamber moves further down until it connects with the air hole 16 on the outer wall of the air tube 9, thereby quickly restoring the original negative pressure and releasing the adsorption force, realizing the reliable release of the electronic component at the target position. The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
