[0027] The turnover material tray provided in the embodiment of the present invention is now described.

[0028] In one embodiment of the present invention, please refer to Figures 1 to 3 The turnover material tray includes a main material tray 1, a sub-material tray 2 and a clamping assembly 3. The main material tray 1 is provided with a plurality of material tray cavities 11. A sub-material tray 2 can be placed in a material tray cavity 11. The sub-material tray 2 is clamped in the corresponding material tray cavity 11 by the clamping assembly 3. The sub-material tray 2 is provided with a plurality of product placement cavities, and each sub-material tray 2 can hold a plurality of products. When the clamping assembly 3 is loosened, the sub-material tray 2 can be removed from the main material tray 1, and the sub-material tray 2 can be reversed and then placed in the material tray cavity 11, so that the versatility of the turnover material tray can be improved. For example, when the position of the suction nozzle for adsorbing the product is changed, or when the product transportation direction is changed, the turnover material tray can still be used to carry the product. The inner wall of the material tray cavity 11 is detachably connected with a first identification member 4. When the first identification member 4 is connected to the inner wall of the material tray cavity 11, the sub-material tray 2 can be prevented from being reversed. Specifically, when the sub-material tray 2 needs to be placed in a first direction, the first identification member 4 is set at a first predetermined position so that the sub-material tray 2 can only be placed in the first direction; when the sub-material tray 2 needs to be placed in a second direction, the first identification member 4 is set at a second predetermined position so that the sub-material tray 2 can only be placed in the second direction, thereby preventing the sub-material tray 2 from being reversed in direction.

[0029] The turnover tray in the above embodiment includes a main tray 1, a sub-tray 2 and a clamping assembly 3. The main tray 1 has a plurality of tray cavities 11 for placing the sub-trays 2. The clamping assembly 3 clamps the sub-tray 2 in the tray cavity 11. When the placement direction of the product needs to be adjusted, the sub-tray 2 can be removed from the main tray 1, reversed and placed back in the tray cavity 11, making the turnover tray more versatile. The inner wall of the tray cavity 11 is detachably connected with a first identification member 4, which can prevent the sub-tray 2 from being placed in the wrong direction. Before adjusting the direction of the sub-tray 2, adjusting the position of the first identification member 4 can ensure that the sub-tray 2 is placed in the correct direction.

[0030] In one embodiment of the present invention, see Figures 2 to 4 , the sub-tray 2 is square, and accordingly, the tray cavity 11 is also square, so that the inner wall of the tray cavity 11 can limit the sub-tray 2 to a certain extent. One of the corners of the sub-tray 2 has a cut corner 21, so that the first identification member 4 can cooperate with the cut corner 21 to prevent the sub-tray 2 from being placed in the wrong direction. More specifically, two adjacent corners of the tray cavity 11 are each provided with a first positioning hole 121, and the first identification member 4 is inserted into one of the first positioning holes 121 to limit the placement direction of the sub-tray 2. When the first identification member 4 is inserted into one of the first positioning holes 121, the corner of the sub-tray 2 with the cut corner 21 can only be arranged adjacent to the first identification member 4, so that the placement direction of the sub-tray 2 can be limited.

[0031] In other embodiments, a third positioning hole is provided in the sub-tray 2, and the third positioning hole is arranged offset from the center of the sub-tray 2. The bottom wall of the tray cavity 11 is provided with two first positioning holes 121, and the first identification member 4 is inserted into one of the first positioning holes 121. When placing the sub-tray 2, the first identification member 4 needs to pass through the third positioning hole, so that the placement direction of the sub-tray 2 can be limited.

[0032] Optionally, the first identification member 4 is a positioning column or a pin, which can be detachably connected to the main material tray 1 .

[0033] In one embodiment of the present invention, see Figure 1 and Figure 4 , the four corners of the tray cavity 11 can be provided with avoidance parts, and the avoidance parts can be in an arc shape, which can avoid the corners of the sub-tray 2, so as to prevent the corners of the tray cavity 11 and the corners of the sub-tray 2 from interfering with each other when the processing accuracy of the tray cavity 11 is not enough, so that the sub-tray 2 cannot be stably fixed in the tray cavity 11. When one of the corners of the sub-tray 2 has a cut corner 21, and the first positioning holes 121 are provided at the two adjacent corners of the tray cavity 11, and the first positioning holes 121 are also provided at the corners of the tray cavity 11, then three of the avoidance parts can be set as the first avoidance parts 12, and the first positioning holes 121 are provided at the bottom wall of the first avoidance parts 12, and the remaining avoidance part is set as the second avoidance part 13, and the clamping assembly 3 is provided in the second avoidance part 13, so that the clamping assembly 3 is also provided in the tray cavity 11, and will not protrude from the surface of the main tray 1, so as to prevent scratches on the staff.

[0034] In one embodiment of the present invention, see Figure 5 The clamping assembly 3 includes a fastening clamp 31 and an elastic member 32. The fastening clamp 31 is rotatably connected to the main material tray 1. The two ends of the elastic member 32 are elastically connected to the fastener and the main material tray 1 respectively. Under the action of the elastic member 32, the fastening clamp 31 can abut against the corner of the sub-material tray 2. Under the push of the fastening clamp 31 and the combined action of the inner wall of the tray cavity 11, the sub-material tray 2 can be clamped to prevent the sub-material tray 2 from shaking and causing the product to shake out during the transportation of the turnover tray. More specifically, the fastening clamp 31 has a clamping notch 311, which is used to abut against the corner of the sub-material tray 2, so that the sub-material tray 2 is clamped. Among them, the clamping notch 311 can be fan-shaped, so that at least one side of the clamping notch 311 can abut against the side wall of the sub-material tray 2.

[0035] Optionally, the rotation axis of the fastening clamp 31 is arranged perpendicularly to the bottom surface of the tray cavity 11, so that the fastening clamp 31 can be arranged on the bottom surface of the tray cavity 11 and rotate. In this way, the fastening clamp 31 always rotates inside the tray cavity 11 and does not protrude from the surface of the main tray 1, which can prevent the staff from being scratched. More specifically, the fastening clamp 31 is in the form of a sheet and is arranged on the bottom surface of the tray cavity 11. Optionally, the fastening clamp 31 and the main tray 1 are rotatably connected by a pin shaft, and a first pin shaft hole 312 is provided on the fastening clamp 31, and a second pin shaft hole 131 is provided on the bottom wall of the tray cavity 11. The pin shaft passes through the first pin shaft hole 312 and the second pin shaft hole 131, so that the fastening clamp 31 is rotatably connected to the main tray 1.

[0036] Optionally, the second avoidance portion 13 is provided at one corner of the tray cavity 11, and the fastening clip 31 is disposed in the second avoidance portion 13, and the opening direction of the pressing notch 311 faces the interior of the tray cavity 11, so that the opening direction of the pressing notch 311 is directly opposite to the corner of the sub-tray 2. The second avoidance portion 13 may be in an arc shape.

[0037] Optionally, a receiving hole 313 is provided on the side of the fastening clamp 31, one end of the elastic member 32 extends into the receiving hole 313, and the two ends of the elastic member 32 abut against the inner wall of the receiving hole 313 and the side wall of the tray cavity 11 respectively. The receiving hole 313 can limit the elastic member 32 to prevent the elastic member 32 from shaking. When preparing to place the sub-tray 2, the fastening clamp 31 is rotated relative to the main tray 1, the elastic member 32 is compressed, and then the sub-tray 2 is placed in the tray cavity 11, and the fastening clamp 31 is released. The fastening clamp 31 rotates and clamps the sub-tray 2 under the action of the elastic member 32. When the fastening clamp 31 is set in the second avoidance portion 13, the two ends of the elastic member 32 abut against the inner wall of the receiving hole 313 and the side wall of the second avoidance portion 13 respectively. Optionally, the elastic member 32 is a spring.

[0038] In one embodiment of the present invention, the main material tray 1 is a metal material tray, which is used to replace the commonly used plastic material tray. The plastic material tray is easy to deform and damage, and the flatness and precision are not high, which will affect the test efficiency and test precision of the product. In addition, the plastic material tray needs to be replaced regularly, which increases the test cost. The metal material tray can be made of a lighter material such as aluminum, which has a stable shape and is not easy to deform. It can be matched with the first identification member 4 and the second identification member 5 described below to identify the direction of the sub-tray 2.

[0039] In one embodiment of the present invention, see Figure 3, a hollow hole 14 is provided on the main material tray 1. The setting of the hollow hole 14 makes the bottom part of the material tray cavity 11 hollow, so as to reduce the weight of the main material tray 1. In particular, when the main material tray 1 is a metal material tray, the weight of the metal material tray can be greatly reduced, and the load of the material tray transportation mechanism can be reduced. Optionally, the hollow hole 14 can be provided in a partial area corresponding to the bottom of each material tray cavity 11, or it can connect two adjacent material tray cavities 11. The shape of the hollow hole 14 is not limited here, as long as it can still support the sub-material tray 2 after the hollow hole 14 is provided. Among them, the structure of the sub-material tray 2 is not limited here, and it can be a plastic material tray or a metal material tray.

[0040] In one embodiment of the present invention, see Figure 2 and Figure 4 The main material tray 1 is square, and two adjacent corners of the main material tray 1 are provided with second positioning holes 15, and a second identification member 5 is connected to one of the second positioning holes 15, and the second identification member 5 is used to mark the placement direction of the main material tray 1. The second identification member 5 can be a marking screw or a marking pin, which can be connected to one of the second positioning holes 15. More specifically, the two second positioning holes 15 can be set on both sides of the length direction of the main material tray 1. When the main material tray 1 needs to be placed in the first direction, the second identification member 5 can be inserted into one of the second positioning holes 15 for easy identification by the staff. When the main material tray 1 needs to be placed in the second direction, the second identification member 5 is inserted into the other second positioning hole 15 for easy identification by the staff.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
