[0015] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0016] like Figures 1-4As shown in the figure, a turnover mechanism for an electronic component tray has a mounting substrate 1. On the mounting substrate 1, there are a pair of oppositely arranged cylinder mounting plates 10. The first turnover cylinder 2 and the second turnover cylinder 3 are respectively installed on the outer sides of the cylinder mounting plates 10. On the mounting substrate 1 and between the two cylinder mounting plates 10, there are the first bearing seat 11, the second bearing seat 12, and the third bearing seat 13 spaced apart. The third bearing seat 13 is located between the first bearing seat 11 and the second bearing seat 12. A first turnover shaft 21 connected to the first turnover cylinder 2 is installed between the first bearing seat 11 and the third bearing seat 13 through the first bearing group 20. A second turnover shaft 31 connected to the second turnover cylinder 3 is installed between the second bearing seat 12 and the third bearing seat 13 through the second bearing group 30. And the first turnover shaft 21 and the second turnover shaft 31 are on the same axis. The output ends of the first turnover cylinder 2 and the second turnover cylinder 3 are respectively connected and driven to the first turnover shaft 21 and the second turnover shaft 31 through the couplings 201 and 301. The first turnover shaft 21 is connected to the first turnover table assembly 4, and the second turnover shaft 31 is connected to the second turnover table assembly 5. The first turnover table assembly 4 and the second turnover table assembly 5 are respectively located on both sides of the axis and can be turned around the axis. That is, the first turnover cylinder 2 can drive the first turnover table assembly 4 to turn through the first turnover shaft 21, and the second turnover cylinder 3 can drive the second turnover table assembly 5 to turn through the second turnover shaft 31, so as to align the trays adsorbed on the two turnover table assemblies and transfer the electronic components and realize the turning over of the electronic components.

[0017] Specifically, the first turnover table assembly 4 includes a first tray turnover table 41, two first turnover arms 42 arranged on one side of the first tray turnover table 41, and a first vacuum adsorption plate 43 arranged on the first tray turnover table 41. And one of the first turnover arms 42 is fixedly connected to the first turnover shaft 21, and the other first turnover arm 42 is movably connected to the second turnover shaft 31 through a bearing. The second turnover table assembly 5 includes a second tray turnover table 51, two second turnover arms 52 arranged on one side of the second tray turnover table 51, and a second vacuum adsorption plate 53 arranged on the second tray turnover table 51. And one of the second turnover arms 52 is fixedly connected to the second turnover shaft 31, and the other second turnover arm 52 is movably connected to the first turnover shaft 21 through a bearing. The two first turnover arms 42 and the two second turnover arms 52 are arranged in a staggered manner along the same axis. In this way, the turning of the two turnover table assemblies does not interfere with each other and has a more stable and balanced supporting performance, ensuring uniform and stable force during the turning process. The trays are respectively positioned on the first tray turnover table 41 and the second tray turnover table 51 and are respectively adsorbed by the first vacuum adsorption plate 43 and the second vacuum adsorption plate 53 to keep their positions fixed during the turning process.

[0018] Further, support blocks 14 for supporting the first flipping table assembly 4 and the second flipping table assembly 5 are respectively provided at both ends of the mounting substrate 1. A buffer 141 is provided on the support block 14 so as to keep the flipping table assembly horizontal and stable in the open state, and to provide a buffering effect at the moment of contact, avoiding excessive vibration of the components and position deviation;

[0019] Further, a first positioning step surface 411 is provided on the inner side of the first tray flipping table 41; a tray positioning cylinder 15 and a positioning plate 151 driven by the tray positioning cylinder 15 are further installed on the mounting substrate 1 and outside the first tray flipping table 41. The positioning plate 151 has a positioning end protruding towards the first tray flipping table 41 and is equipped with a positioning wheel 152. In this embodiment, the positioning plate 151 protrudes with two positioning ends and is respectively equipped with a positioning wheel 152, and an avoidance recess 412 for the movement of the positioning end and the positioning wheel 152 is provided on the outside of the first tray flipping table 41; the positioning wheel 152 forms a matching positioning with the trapezoidal positioning recess on the edge of the tray; that is, when the tray is placed on the first tray flipping table 41, it is first limited by the first positioning step surface 411, and then the tray positioning cylinder 15 drives the positioning plate 151 to push towards the positioning step surface. By using the positioning wheel and the trapezoidal positioning recess on the edge of the tray, the tray can be translated along the first positioning step surface 411 to achieve position adjustment in this direction and realize positioning. After positioning, the tray is adsorbed and fixed by the first vacuum adsorption plate 43 of the first tray flipping table 41, and then the tray positioning cylinder 15 drives the positioning plate 151 and the positioning wheel 152 to leave the tray.

[0020] The output end of the tray positioning cylinder 15 is arranged outward and is connected to the positioning plate 152 through a connecting block 153 and a horizontal slide rail machine assembly 154. The connecting block 153 and the horizontal slide rail assembly 154 are located above the tray positioning cylinder 15, with a compact structure.

[0021] A plurality of positioning columns 531 are provided on the second vacuum adsorption plate 53 to achieve corresponding positioning with the positioning holes on the empty tray. The tray b on the second tray flipping table 51 can have a different specification from the tray a on the first tray flipping table 41, so that the electronic components can be turned over and transferred to another specification of tray as needed, facilitating subsequent processing operations.

[0022] Combined with Figure 4As shown in the figure, when flipping, place the tray full of electronic components on the first tray flipping table surface 41 and the first vacuum adsorption plate 43 of the first flipping table surface assembly 4 for positioning and adsorption fixation. Place the empty tray on the second tray flipping table surface 51 and the second vacuum adsorption plate 53 on the other side for positioning and adsorption. Then, drive the second tray flipping table surface 51 and the empty tray to rotate through the second flipping cylinder 3, the second flipping shaft 31, and the second flipping arm 52, and cover them on the full tray of the first flipping table surface assembly 4, so that the electronic components are aligned into the empty tray. Under the action of the second flipping cylinder 3, keep the two trays in a relatively clamped state. Then, drive the first flipping table surface assembly 4 and the second flipping table surface assembly 5 as a whole to flip to the other side through the first flipping cylinder 2, the first flipping shaft 21, and the first flipping arm 42, so that the full tray is on the top and the empty tray is on the bottom and flipped to the side where the second flipping table surface assembly 5 was initially located. At this time, the electronic components on the original full tray automatically enter the cells of the original empty tray and complete the flipping. Then, the first flipping cylinder 2 drives the first flipping table surface assembly 4 and the tray to return, and then remove the trays respectively to complete the flipping of the whole tray of components.

[0023] The utility model can greatly improve the flipping efficiency of components, thereby facilitating subsequent processing. The overall structure of the tray flipping mechanism of the utility model is compact, with strong stability, and can also be flexibly adjusted according to the tray specifications to achieve versatility, thus saving costs.

[0024] The above embodiments are only the preferred embodiments of the utility model, which are only used to explain the utility model rather than limit the utility model. Any changes, substitutions, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principle of the utility model shall be equivalent replacement methods and shall be included in the protection scope of the utility model.
