Description

Technical Field

[0001] This utility model belongs to the technical field of component feeding and picking equipment for electronic component testing, and particularly relates to a high-speed picking mechanism for small-sized electronic component testing machines. Background Technology

[0002] Small electronic components such as capacitors, inductors, electronic chips, and crystal oscillators require performance testing during production; each product needs to be tested online. To achieve efficient and automated testing, for scattered electronic components, the through-slot uses a vibration feeding method combined with a suction nozzle transfer method for picking and feeding. However, for the testing of some crystal oscillators, the placement and angle of the product have high requirements, so simple vibration feeding and ordinary suction nozzle formulations cannot meet the requirements. Even with multiple suction nozzles, each picking up components independently, problems such as low picking efficiency and non-compact equipment structure still exist. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed material handling mechanism for a small-sized electronic component testing machine, which aims to solve the problems of non-compact structure, slow operating speed, and low material handling efficiency in the existing material handling mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed material handling mechanism for a small-sized electronic component testing machine, comprising a first mounting plate and a second mounting plate. The first mounting plate has a material loading station, a rotational correction station, and a four-sided correction station, all located on the same horizontal plane and on the same axis, and arranged at equal intervals. Three vacuum nozzles, moving synchronously and with the same nozzle height and facing downwards, are mounted on the second mounting plate. The distance between the three vacuum nozzles is equal to the distance between the material loading station and the rotational correction station. The spacing between the four sides of the calibration station is equal; a transverse guide rail and a transverse slider are mounted on the surface of the second mounting base facing the first mounting base. A connecting block is mounted on the transverse slider, and a longitudinal slider and a longitudinal guide rail are mounted on the connecting block. A "T"-shaped mounting plate is connected to the upper end of the longitudinal guide rail. The side of the T-shaped mounting plate is connected to the three vacuum nozzles respectively through three sets of nozzle bracket assemblies; a first motor is mounted on the surface of the second mounting base facing away from the first mounting base. The output end of the first motor is movably connected to the lower end of the longitudinal guide rail through a swing arm and a connecting shaft.

[0005] Furthermore, a CCD industrial camera is provided above the loading station, and the CCD industrial camera is connected to a second motor installed below the first mounting substrate. The second motor is connected to the turntable of the rotation correction station through a synchronous pulley assembly. The turntable is provided with vacuum adsorption holes for adsorbing workpieces.

[0006] The first mounting base is arranged horizontally, and the second mounting base is arranged vertically. The industrial CCD camera is mounted and suspended above the loading station via a camera bracket. The first mounting base, the second mounting base, and the camera bracket are respectively mounted on the machine table.

[0007] Furthermore, the four-sided correction station has a flat plate suspended on the first mounting base. A workpiece seat is provided in the middle of the flat plate for placing the workpiece. A pair of parallel slide rails and slide blocks are provided on both sides of the workpiece seat. Positioning seats are respectively installed on the slide blocks, and a positioning block is connected to each positioning seat. The two positioning blocks are centrally symmetrically arranged, and the inner side of the positioning blocks has positioning surfaces that are oppositely arranged. When the two positioning blocks move towards each other to the positioning position, the resulting positioning position is located above the surface of the workpiece seat. A third motor is also installed below the first mounting base. The output end of the third motor extends upward through the first mounting base and is connected to a double-headed swing arm. The double-headed swing arm is located below the flat plate, and the two ends of the double-headed swing arm are respectively connected to the positioning seats above through a bent connector. That is, the third motor synchronously drives the double-headed swing arm, thereby synchronously driving the two positioning seats and positioning blocks to move towards each other or separate synchronously, so as to perform four-sided correction on the workpiece located on the workpiece seat.

[0008] Furthermore, a track plate is installed below the transverse guide rail on the side surface of the second mounting base facing the first mounting base. The track plate has a track groove concentric with the output shaft of the first motor. Two guide wheels of equal diameter are installed on the connecting shaft, and the diameter of the guide wheel is equivalent to the inner width of the track groove. One guide wheel is set in the track groove and moves back and forth along the track groove. The other guide wheel is set in the strip-shaped hollow part of the swing arm, and the width of the strip-shaped hollow part is equivalent to the diameter of the guide wheel.

[0009] Furthermore, a crossbar is connected to the lower end of the longitudinal guide rail on the outer side, and photoelectric baffles are connected to both ends of the crossbar; correspondingly, photoelectric sensors are installed on both sides of the surface of the second mounting substrate facing the first mounting substrate. When the longitudinal guide rail moves along the arc-shaped trajectory, the photoelectric baffles on both sides of the lower end will also enter and exit the photoelectric sensors on the corresponding sides along the arc-shaped trajectory.

[0010] Through the above-described structure, the three sets of vacuum nozzles are synchronously driven by a single drive mechanism, which not only improves efficiency but also makes the equipment structure more compact. At the same time, the loading station, rotation correction station, and four-sided correction station perform angle correction and four-sided position correction during the transfer interval, ensuring that the electronic components finally transferred to the testing equipment are in the accurate testing position, thereby helping to ensure the accuracy and efficiency of the test.

Detailed Implementation

[0013] In one embodiment of this utility model, such as Figures 1 to 7 As shown, this utility model describes a high-speed material handling mechanism for a small-sized electronic component testing machine. It includes a first mounting substrate 1 and a second mounting substrate 2. The first mounting substrate 1 is horizontally arranged, and the second mounting substrate 2 is vertically arranged. The first mounting substrate 1 has a loading station 3, a rotational correction station 4, and a four-sided correction station 5, all located on the same horizontal plane and on the same axis, with equal spacing. Three vacuum nozzles 6 are mounted on the second mounting substrate 2, moving synchronously with the same nozzle height and facing downwards. The spacing between the three vacuum nozzles 6 is equal to the spacing between the loading station 3 and the rotational correction station 4. The spacing between the four-sided correction stations 5 is equal; a transverse guide rail 21 and a transverse slider 22 are mounted on the surface of the second mounting base 2 facing the first mounting base 1. A connecting block 23 is mounted on the transverse slider 22. A longitudinal slider 24 and a longitudinal guide rail 25 are mounted on the connecting block 23. A "T"-shaped mounting plate 26 is connected to the upper end of the longitudinal guide rail 25. The side of the T-shaped mounting plate 26 is connected to the three vacuum nozzles 6 respectively through three sets of nozzle bracket assemblies 27; a first motor 7 is mounted on the surface of the second mounting base 2 facing away from the first mounting base 1. The output end of the first motor 7 is movably connected to the lower end of the longitudinal guide rail 25 through a swing arm 71 and a connecting shaft 72.

[0014] Furthermore, the loading station 3 is equipped with a receiving platform 30, which has a receiving groove for receiving electronic components fed by the vibrating feeder 8. A CCD industrial camera 31 is installed above the loading station 3, and the CCD industrial camera 31 is connected to a second motor 41 installed below the first mounting base plate 1. The second motor 41 is connected to the turntable 43 of the rotation correction station 4 through a synchronous pulley assembly 42. The turntable 43 is equipped with vacuum adsorption holes for adsorbing workpieces, so that the workpiece remains stable when placed on it and rotates with the turntable 43. The second motor 41 is also a servo motor. When the workpiece is on the loading station 3, the CCD industrial camera 31 takes a picture to identify the angle of the workpiece, thereby providing data for the rotation angle of the rotation correction station 4. When the workpiece is transferred to the turntable 43 on the rotation correction station 4, the second motor 41 controls the rotation angle of the turntable 43 according to the angle data output by the CCD industrial camera 31, and quickly completes the angle correction in the time of one transfer and return. Similarly, the four-sided correction station also quickly completes the four-sided position correction in the time of one transfer and return.

[0015] The industrial CCD camera 31 is mounted and suspended above the loading station 3 via the camera bracket 32; the first mounting base 1, the second mounting substrate 2, and the camera bracket 3 are respectively mounted on the machine table.

[0016] Furthermore, the four-sided correction station 5 has a flat plate 51 suspended on the first mounting base plate 1. A workpiece seat 52 for placing workpieces is provided in the middle of the flat plate 51. The workpiece seat 52 also has a vacuum adsorption hole for adsorbing workpieces in the middle. A pair of parallel slide rails 53 and slide blocks 54 are provided on both sides of the workpiece seat 52. Positioning seats 55 are respectively installed on the slide blocks 54. A positioning block 56 is connected to each positioning seat 55. The two positioning blocks 56 are centrally symmetrically arranged and the inner side of the positioning blocks 56 is provided with positioning surfaces 561 that are arranged opposite each other. When the two positioning blocks 56 move towards each other to the positioning position, the resulting positioning position is located above the surface of the workpiece seat 52. In this embodiment, the two positioning blocks 56 are respectively provided with positioning surfaces 561 arranged at right angles and are combined. The rectangular four-sided correction surface is suitable for rectangular electronic components. A third motor 57 is also installed below the first mounting base 1. The output end of the third motor 57 extends upward through the first mounting base 1 and is connected to a double-headed swing arm 571. The double-headed swing arm 571 is located below the plate 51. The central axis of the double-headed swing arm 571 is coaxial with the central axis of the workpiece seat 52. The two ends of the double-headed swing arm 571 are respectively connected to the positioning seat 55 above through a bent connector 572. That is, the double-headed swing arm 571 is synchronously driven by the third motor 57 (which is also a servo motor), which in turn synchronously drives the two positioning seats 55 and positioning blocks 56 to move synchronously towards each other or separate along their respective slides 54 and slide rails 53, so as to perform four-sided correction on the workpiece located on the workpiece seat 52.

[0017] Furthermore, a track plate 28 is installed below the transverse guide rail 21 on the side surface of the second mounting base 2 facing the first mounting base 1. The track plate 28 has a track groove 281 concentric with the output shaft of the first motor 7. Two guide wheels 73 of equal diameter are installed on the connecting shaft 72, and the diameter of the guide wheel 73 is approximately equal to the inner width of the track groove 281. One guide wheel 73 is disposed in the track groove 281 and reciprocates along the track groove 281, while the other guide wheel 73 is disposed in the strip-shaped hollow portion 711 of the swing arm 71, and the width of the strip-shaped hollow portion 711 is approximately equal to the diameter of the guide wheel 73. The track groove 281, connecting shaft 72, and guide wheel 73 can make the movement of the swing arm 71 and the longitudinal guide rail 25 more stable, thereby making the arc-shaped lifting and lowering movement of the vacuum nozzle more stable.

[0018] Furthermore, a crossbar 251 is connected to the outer side of the lower end of the longitudinal guide rail 25, and photoelectric baffles 252 are connected to both ends of the crossbar 251. Correspondingly, photoelectric sensors 253 are respectively installed on the two edges of the side surface of the second mounting base 2 facing the first mounting base 1. When the longitudinal guide rail 25 moves along the arc-shaped trajectory, the photoelectric baffles 252 on both sides of the lower end will also enter and exit the photoelectric sensors 253 on the corresponding sides along the arc-shaped trajectory. The photoelectric sensors 253 are connected to the first motor 7 through cables, thereby controlling the rotation direction of the first motor 7, and thus realizing reciprocating picking and feeding.

[0019] In this embodiment, the first motor 7 is a servo motor, which rotates forward and backward to drive the swing arm 71 to swing. The swing arm 71 then drives the longitudinal guide rod 25 to move up and down, and at the same time, it also moves laterally along the transverse guide rail 21 through the connecting block 23 and the transverse slider 22. This makes the motion trajectory output by the upper end of the longitudinal guide rod 25 arc-shaped, moving up and down repeatedly. Then, through the "T"-shaped mounting plate 26 and the three sets of suction nozzle bracket assemblies 27, it synchronously drives the three vacuum suction nozzles 6 to move synchronously above the loading station 3, the rotation correction station 4, and the four-sided correction station 5. As shown in the figure, when the first vacuum suction nozzle 6 on the right is located on the loading station 4, the second vacuum suction nozzle in the middle is exactly located on the rotation correction station 4, and the third vacuum suction nozzle is exactly located on the four-sided correction station 5. Then, the first motor 7 drives the swing arm 71 to swing. Driven by the drive and transmission components of machine 7, the three vacuum nozzles 6 move simultaneously, picking up the workpieces they have collected. Following an arc-shaped trajectory, the workpiece on the first vacuum nozzle is transferred from the loading station 3 to the rotary calibration station 4, while the workpiece on the second vacuum nozzle is transferred from the rotary calibration station 4 to the four-sided calibration station 5. The workpiece originally on the third vacuum nozzle is then transferred from the four-sided calibration station 5 to the testing station of the testing equipment, completing the feeding operation. In other words, the workpiece is relay-transferred from the loading station 3 to the rotary calibration station 4 for rotational calibration. After the angle of the workpiece is adjusted, it is transferred to the four-sided calibration station 5 to adjust the four-sided position of the workpiece, and finally transferred to the testing station for testing. In use, the testing equipment is arranged in… Figure 1 On the left side of the position shown, the material receiving point is adjacent to the first vacuum nozzle on the left.

[0020] In summary, through the above-described structure, the three sets of vacuum nozzles are synchronously driven by a single drive mechanism, which not only improves efficiency but also makes the equipment structure more compact. Furthermore, the loading station, rotation correction station, and four-sided correction station perform angle and four-sided position corrections during the transfer interval, ensuring that the electronic components finally transferred to the testing equipment are in accurate testing positions, thereby helping to ensure the accuracy and efficiency of the test.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
