[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] See also Figure 1 to Figure 2 A PCBA turnover plate provided in a first embodiment of the utility model comprises a plate body 1, wherein the upper surface of the plate body 1 is recessed downward to form a plurality of receiving grooves 11 for storing PCBAs, wherein the receiving grooves 11 comprise a plurality of side walls 111 for limiting the edge position of the PCBA, and a groove bottom 112 perpendicular to the plurality of side walls 111, wherein the receiving grooves 11 further comprise notches 14 arranged on the side walls 111, wherein the plurality of receiving grooves 11 are arranged in a linear array, wherein the upper surface of the plate body 1 is recessed downward to form a groove 13, wherein the groove 13 is arranged perpendicular to the plurality of receiving grooves 11, wherein the groove 13 comprises a plurality of groove walls 131 forming a step structure with the groove bottom 112, and a groove bottom 132 arranged perpendicular to the groove walls 131, wherein the plate body 1 further comprises adsorption surfaces 12 located on both sides of the receiving groove 11 for adsorbing the plate body 1.

[0022] In this real-time example, the linear array arrangement of the receiving grooves 11 facilitates the robot arm to pick up the PCBA board, and the groove wall 131 and the groove bottom 112 form a step structure. It can be understood that the groove wall 131 and the groove bottom 112 are arranged vertically, and the vertical distance from the groove bottom 112 to the upper surface of the PCBA board is smaller than the vertical distance from the groove bottom 132 to the surface of the PCBA tray. When the PCBA trays are stacked, the middle of the PCBA tray will be concave downward due to gravity. Since the groove 13 is provided and the groove wall 131 is vertical to the PCBA The upper surface of the BA tray is in the same horizontal plane as the direction of gravity, so that the force of gravity acts on the side of the groove wall 131, playing a role similar to a reinforcing rib, thereby preventing the lower PCBA board from being depressed downward due to excessive weight in the middle during stacking. It should be noted that the vertical groove wall 131 needs to have a certain thickness outside the edge of the PCBA tray, otherwise when gravity and the groove wall 131 are not in the same plane, the PCBA tray is not strong enough due to high pressure, causing the groove wall 131 to be pulled to both sides and not play the role of a reinforcing rib. In addition, since the depression depth of the groove 13 is deeper than the receiving groove 11, the groove 13 can also be used as a material extraction port of the receiving groove 11 to realize the function of manually taking the PCBA board. The operator can touch the bottom of the PCBA board through the groove 13 formed by the depression, hook up the PCBA board and take it. One or more grooves 13 may be provided. In the present embodiment, since the middle part of the receiving groove 11 is most depressed during the stacking process of the disk body 1, only one groove 13 is provided in the present embodiment, and it is provided in the middle part of the receiving groove 11. Preferably, the groove 13 is provided in the middle part of the receiving groove 11.

[0023] Specifically, by Figure 1 It can be seen that the receiving groove 11 is used to store rectangular PCBA boards. In this embodiment, five receiving grooves 11 are provided. In order to facilitate the storage of the PCBA board, a notch 14 is provided on the side wall 111 of the receiving groove 11 to avoid the impact of components on the upper surface of the PCBA board. Of course, the receiving groove 11 can also be directly expanded to place the PCBA board into the receiving groove 11. The problem caused by this is that in the process of the PCBA board sliding left and right, all the force points are concentrated on the protruding components, which can easily cause the components to be desoldered and damaged, and unbalanced shaking occurs.

[0024] In this embodiment, an adsorption surface 12 for machine adsorption is provided on the upper surface of the disc body 1. In order to facilitate the adsorption of the machine, the surface of the entire disc body 1 is smoothed, and the overall warping degree needs to be ≤3mm, which is conducive to the vacuum suction cup on the machine to form a good airtightness when sucking the disc body 1. At the same time, in order to prevent the adsorption surface 12 from being smooth and getting stuck in the state of multi-layer stacking, five grooves 17 are arranged in a linear array in the middle of the adsorption surface 12, wherein the number of grooves 17 can be selected according to the size of the suction cup to select the width that needs to be reserved in the middle, so as to evenly distribute the number of grooves 17. The shape of the grooves 17 can be freely selected. In this embodiment, a rounded triangle is selected, which can also mainly serve as a direction mark. Specifically, the disc body 1 is provided with a plurality of grooves 17, and the groove 17 array is arranged on the adsorption surface 12.

[0025] See also Figure 2 In this embodiment, in order to facilitate placement and stacking, the tray body 1 has a side plate 2 at the lower edge of the tray body 1. When placed alone, the side plate 2 can play the role of a base support, and when stacked, it plays the role of covering the upper surface of the tray body 1 at the lower end. Specifically, the tray body 1 also includes a side plate 2 formed by extending downward from the edge of the tray body 1. For the stability of stacking, the tray body 1 is provided with a support platform 15 and a press platform 16 used in conjunction with the support platform 15. When stacking, the upper press platform 16 overlaps with the lower support platform 15. At this time, the back of the upper tray body 1 contacts and abuts against the upper surface of the lower tray body 1 to complete the stacking. Specifically, the tray body 1 is provided with a plurality of support platforms 15, and the support platforms 15 are located on the side plates 2. The lower surface of the tray body 1 is provided with a press platform 16 used for stacking in conjunction with the support platforms 15. It should be noted that at least four support platforms 15 are provided, and they are symmetrically provided on the opposite sides of the tray body 1. In this embodiment, twenty-two support platforms 15 are provided, which have better stability.

[0026] In actual use, the bottom of the tray body 1 placed alone does not look beautiful and does not have a certain degree of stability, so a bottom plate 3 is formed by extending outward from the edge of the side plate 2. The reinforced side plate 2 has a certain stabilizing effect and increases the contact area between the bottom and the bottom surface. In the stacked state, it can be used as a contact edge for separation and lifting, and has a visually distinct effect. Specifically, the tray body 1 also includes a bottom plate 3 formed by extending outward from the lower edge of the side plate 2.

[0027] In this embodiment, the tray body 1 is rectangular. In order to facilitate the identification of one direction, the rectangular tray body 1 is chamfered for direction identification when the PCBA parts are placed and for quick positioning when stacked. The other corners are chamfered to disperse the force. Specifically, the tray body 1 is rectangular with missing corners.

[0028] In summary, a PCBA turnover tray in the above-mentioned embodiment of the utility model is provided with a receiving groove of a specific size for storing PCBA boards on the tray body, and a groove is provided in the middle of the vertical receiving groove to prevent the tray body from sinking downward due to gravity and crushing the PCBA parts at the bottom in the stacking state, and a support platform and a pressing platform used in conjunction with the support platform are provided on the side of the tray body, so that the tray body can complete a stable stacking function. In order to enable the tray body to be connected to the automatic loading function, adsorption surfaces are reserved on both sides of the tray body at the receiving groove for body adsorption and transportation, so as to implement automatic loading, improve loading efficiency, and reduce labor costs.
