The process of sorting and inspecting electronic components (such as memory cards) generally includes transporting a tray carrying the components to be inspected from a preparation position to an inspection position for inspection, transporting the tray to a sorting position after inspection, and picking out defective products by a pick-and-place mechanism according to the inspection result and moving the tray to another tray. Today's inspection sorters perform the inspection of electronic components of different sizes, so that the tray has a specific matrix layout according to the size of the electronic components, so that each electronic component is confined to a slot of a size corresponding to it.
The above pick-and-place mechanism is generally provided with a plurality of pick-and-place devices on a cross beam, and the pick-and-place devices generate suction force by adopting a vacuum suction technology so as to pick electronic components at specific positions from the tray. Based on the size differences of the electronic components and the spacing on the tray, the width distance between the various pickers must be adjustable to enable their nozzles to align with the electronic components.
Some previous patents disclose techniques for taking and placing the pitch. For example:

Detailed Description
For the purpose of illustrating the present invention, the following embodiments will be described with reference to the accompanying drawings. The various objects of the embodiments are depicted in terms of scale, dimensions, amounts of deformation or displacement suitable for illustration, rather than in terms of actual component proportions, as previously described. And in the following description, like components are denoted by the same reference numerals.
The interval simultaneous adjustment mechanism shown in fig. 1 is provided with a first transmission rod 11, a second transmission rod 12 and a positioning rod 13 horizontally disposed on a frame 10; the first transmission rod 11 is provided with a first threaded section 111 and a second threaded section 112, and a non-threaded section 113 is arranged between the first threaded section and the second threaded section; the second transmission rod 12 is also provided with a first threaded section 121 and a second threaded section 122 with an unthreaded section 123 therebetween. The first thread section and the second thread section of each transmission rod are both reverse threads. The pitch of the teeth of the threaded section of the first transmission rod 11 is greater than the pitch of the teeth of the threaded section of the second transmission rod 12.
As shown in fig. 3, a driving source 50 controls the first transmission lever 11 and the second transmission lever 12 to rotate in the same direction. The driving source 50 includes: a first driving wheel 51 for driving the first transmission rod 11, a second driving wheel 52 for driving the second transmission rod 12, a driving wheel 53 in driving-driven relationship with the first driving wheel 51, and an idle wheel 54 between the first driving wheel 51 and the second driving wheel 52. The rotation of the driving wheel 53 can achieve the purpose of rotating the first and second transmission rods 11, 12 in the same direction and at the same speed by the master-slave relationship of each wheel.
A fixed pick-and-place device 20 is fixed to a reference position of the frame 10 by a fixed mounting module 25. A plurality of mobile pick-and-place devices 40 are respectively mounted on the first transmission bar 11 and the second transmission bar 12 by respective sliding type mounting modules 30 and are arranged on both sides of the fixed pick-and-place device 20 in an even number. The sliding type installation module 30 includes a carrier 31, a nut 32 matching with the threaded section of the transmission rod is fixed at the rear of the carrier 31, and a sliding member 33 matching with the positioning rod 13. The nut 32 is assembled to the first threaded section or the second threaded section, and the sliding member 33 is assembled to the positioning rod 13.
For convenience of describing the arrangement and adjustment of the mobile pick-and-place devices 40, the mobile pick-and-place devices 40 are referred to as a first unit 41, a second unit 42, a third unit 43, and a fourth unit 44, respectively. Wherein,
the first unit 41 is mounted on the first threaded section 111 and the positioning rod 13 of the first transmission rod 11.
The second unit 42 is mounted on the first threaded section 121 and the positioning rod 13 of the second transmission rod 12.
The third unit 43 is mounted on the second threaded section 122 of the second transmission rod 12 and the positioning rod 13.
The fourth unit 44 is mounted on the second threaded section 112 of the first transmission rod 11 and the positioning rod 13.
As shown in fig. 2, when the driving source 50 is started and the first driving lever 11 and the second driving lever 12 rotate synchronously in the same speed and the same direction, the first unit 41 and the second unit 42 move in the same direction and the third unit 43 and the fourth unit 44 move in the same direction based on the relationship of the reverse screw threads, but the moving directions of the two sets are opposite. The moving distance of each moving unit is different due to the different thread pitch. Therefore, the plurality of mobile pick-and-place devices 40 can perform the adjustment of the same movement but different displacement distances with respect to the fixed pick-and-place device 20, and finally obtain the equal spacing.
