[0028] Specifically, as Figures 1 to 6As shown, in the embodiment of the present utility model, a Tray tray provided in this embodiment includes a square Tray tray body 10. On the front surface of the Tray tray body 10, there are two rows of PCBA placement areas 20. In each PCBA placement area 20, a number of PCBA placement slots 21 are arranged at equal intervals. The axial direction of the PCBA placement slots 21 is parallel to the width direction of the Tray tray body 10. A number of PCBA placement slots 21 are connected by support slots 22. The axial direction of the support slots 22 is parallel to the length direction of the Tray tray body 10. The depth of the support slots 22 is greater than the depth of the PCBA placement slots 21, so that the PCBA to be transferred placed in the PCBA placement slots 21 straddles the support slots 22. A number of positioning grooves 11 are provided around the Tray tray body 10. The positioning grooves 11 are used to improve the stability when a number of Tray tray bodies are stacked.
[0029] Optionally, in this embodiment, the Tray tray body 10 is an overall thin-walled structure. The PCBA is a vehicle-mounted display circuit board and is overall long strip-shaped. On the front surface of the Tray tray body, there are two rows of PCBA placement areas 20. A number of long strip-shaped PCBA placement slots 21 are arranged at equal intervals in each row of PCBA placement areas 20. The axial direction of the long strip-shaped PCBA placement slots 21 is parallel to the width direction of the Tray tray body 10 and is used to place the long strip-shaped PCBA. In the middle area at the bottom of the number of long strip-shaped PCBA placement slots 21 arranged at equal intervals, there is a support slot. The axial direction of the support slot 22 is parallel to the length direction of the Tray tray body 10. The depth of the support slot 22 is greater than the depth of the PCBA placement slot 21. That is to say, on the back surface of the Tray tray body 10, the support slot 22 is a protruding support structure relative to the Tray tray body 10. In this application, by providing the support slot 22 perpendicular to the PCBA placement slot 21, the deflection of the Tray tray body 10 in the width direction is increased, and the depression caused by pressure is prevented, thereby protecting the PCBA. Further, a number of positioning grooves 11 are provided around the front surface of the Tray tray body 10. Similarly, the positioning grooves 11 are also protruding positioning structures on the back surface of the Tray tray body 10. By providing a number of positioning grooves 11 around the front surface of the Tray tray body 10, when the Tray trays are stacked, the protruding positioning structure on the back surface of the upper Tray tray is fitted with the positioning grooves on the front surface of the lower Tray tray, and a relatively stable stacking state can be formed, preventing the stacked tray trays from collapsing.
[0030] Optionally, in this embodiment, the square Tray tray body 10 includes four top corners, and a direction mark is provided at one of the top corners. In this embodiment, the stacked trays are isolated through the top corners around the perimeter, and the isolation gap is greater than the distance between the bottom of the upper support groove and the lower PCBA board, so that a gap is reserved between the support groove of the upper tray and the PCBA board of the lower tray to prevent the PCBA board from being pressed. Preferably, as Figure 1 shown, a direction mark is provided at the upper right corner of the Tray tray body 10, and the direction mark is a bevel cut angle 12, and the other three top corners are all rounded corners 13. By setting a unified direction mark, it is convenient to stack the Tray tray body 10 in order, and the other top corners are rounded to facilitate the dispersion of force; further, the warpage of the Tray tray body is ≤3 mm, and it can be injection molded from an anti-static transparent PET material; further, positioning marks 14 are provided on the periphery of the front surface of the Tray tray body 10, and the positioning marks 14 are provided to facilitate the positioning and clamping of the Tray tray body 10.
[0031] Optionally, in this embodiment, pick-and-place grooves 23 are provided on both sides of the PCBA placement groove 21 along its length direction, and the depth of the pick-and-place groove 23 is less than the depth of the PCBA placement groove 21. The pick-and-place groove 23 facilitates the picking and placing of the PCBA in the PCBA placement groove 21. Further, in this embodiment, the length of the Tray tray body 10 is 445 ± 1 mm, the width is 330 ± 1 mm, the height is 11.5 ± 0.5 mm, and the thickness of the Tray tray body 10 is 0.8 mm. The length of the PCBA placement groove 21 is 120.5 ± 0.5 mm, the width is 30.5 ± 0.5 mm, and the depth is 9.5 ± 0.2 mm. The length of the support groove 22 is 416 ± 0.5 mm, the width is 20 ± 0.5 mm, and the depth difference between the support groove 22 and the PCBA placement groove 21 is 1.5 mm. That is, the protruding height of the support structure protruding from the back surface of the Tray tray body 10 is 1.5 mm.
[0032] Optionally, in this embodiment, as Figure 6As shown in the figure, the positioning groove 11 has an open structure on the side close to the outer side of the Tray tray body 10. A card slot 15 is provided on the side of the positioning groove 11 close to the inner side of the Tray tray body 10. The card slot 15 is used to improve the stability when a plurality of Tray tray bodies are stacked. Optionally, in this embodiment, the Tray tray body 10 is made of PET material as a whole and has a certain elasticity. The positioning groove 11 is provided at the four peripheral edges of the Tray tray body 10. The outer side of the positioning groove 11 has an open structure, and a card slot is provided inside the opposite side of the open side. The back of the card slot 15 is a convex structure. When stacking the Tray trays, the convex back of the card slot 15 of the upper Tray tray fits with the front of the card slot 15 of the lower Tray tray, so that the convex back of the card slot 15 of the upper Tray tray is snapped into the card slot 15 of the lower Tray tray, greatly improving the stacking stability. On the other hand, the setting of the positioning groove and the card slot can also effectively prevent the difficulty of separation due to the suction force between the upper and lower Tray trays when the Tray trays are separated.
[0033] In summary, the Tray tray provided in this embodiment includes a square Tray tray body 10. Two rows of PCBA placement areas 20 are provided on the front of the Tray tray body 10. A plurality of PCBA placement slots 21 are equidistantly arranged in each PCBA placement area 20, and multiple PCBA can be transported simultaneously. The axial direction of the PCBA placement slots 21 is parallel to the width direction of the Tray tray body 10. A plurality of PCBA placement slots 21 are connected by support slots 22. The axial direction of the support slots 22 is parallel to the length direction of the Tray tray body 10. The depth of the support slots 22 is greater than the depth of the PCBA placement slots 21, so that the PCBA to be transferred placed in the PCBA placement slots 21 straddles the support slots 22. On the back of the Tray tray body 10, the support slots 22 are protruding support structures relative to the Tray tray body 10. In this application, by providing the support slots 22 perpendicular to the PCBA placement slots 21, the deflection of the Tray tray body 10 in the width direction is increased, and the depression caused by pressure is prevented to protect the PCBA. Similarly, the positioning groove 11 is also a protruding positioning structure on the back of the Tray tray body 10. By providing a plurality of positioning grooves 11 around the front of the Tray tray body 10, when stacking the Tray trays, the protruding positioning structure on the back of the upper Tray tray is fitted with the positioning grooves on the front of the lower Tray tray, and a relatively stable stacking state can be formed to prevent the stacked tray trays from collapsing.
