[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Please refer to them. Figures 1 to 8 The figure shown is a preferred embodiment of the present invention.

[0030] It should be understood that, unless otherwise expressly specified and limited, in this application, the terms "upper," "lower," "front," "rear," "left," "right," etc., indicate the orientation or positional relationship based on the illustrations and are only for the convenience of description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed or operated in a specific orientation.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "set", "connect", "connect", "fixed" and other such terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part.

[0032] It should be noted that in the following embodiments and accompanying drawings, components unrelated to the present invention have been omitted and not shown; and for ease of understanding, the size ratios between the components are exaggerated and differ from the actual product.

[0033] Reference Figure 1 and Figure 2 , Figure 1 A tray jig 100 is provided as an embodiment of the present utility model. The tray jig 100 includes a base 10 and a first nested jig 20.

[0034] The base 10 has an upwardly opening first positioning groove 11, which can be used to accommodate a first-size tray 1.

[0035] The first nested fixture 20 is movably disposed inside the first positioning groove 11, including a first main board 21, and a second positioning groove 22 is formed inside the first main board 21. The second positioning groove 22 can be used to accommodate a second-size tray 2.

[0036] When the tray jig 100 accommodates the tray 1 of the first size, the first main board 21 is pressed and moves downward in the vertical direction to expose the opening of the first positioning groove 11.

[0037] By setting the base 10 and the first nested fixture 20, the tray fixture 100 can be flexibly adjusted according to different sizes of the tray, thereby improving the versatility and applicability of the fixture.

[0038] When it is necessary to accommodate the first size tray 1, simply place the tray in the first positioning groove 11 of the base 10. At this time, the first main board 21 of the first nested fixture 20 will be pressed by the tray and move downward in the vertical direction, thereby exposing the opening of the first positioning groove 11, which facilitates the stable positioning and removal of the first size tray 1.

[0039] When it is necessary to accommodate the second-sized tray 2, the tray can be placed in the second positioning groove 22 of the first nested fixture 20. At this time, the second positioning groove 22 can provide suitable positioning to ensure the stability of the second-sized tray 2. In this way, two different sizes of trays, the first-sized and the second-sized tray 2, can be stored compatiblely, improving the applicability and flexibility of the tray fixture 100.

[0040] The movable design of the first motherboard 21 allows for automatic space adjustment when accommodating trays of different sizes, eliminating the need to change different fixtures and saving operation time and fixture costs.

[0041] Furthermore, the first nested fixture 20 also includes a first elastic element 23, one end of which is connected to the bottom of the first main board 21, and the other end is fixed to the bottom wall of the first positioning groove 11.

[0042] The first elastic element 23 is disposed between the bottom of the first positioning groove 11 and the first main board 21, and is used to provide support and reset force for the first main board 21.

[0043] When the first size tray 1 needs to be accommodated, the first motherboard 21 will be compressed and move in the vertical direction, and the first elastic element 23 will be compressed and store elastic potential energy. When the first size tray 1 is removed, the first elastic element 23 releases elastic potential energy, pushing the first motherboard 21 to move in the vertical direction back to the initial position, so that the first positioning groove 11 is covered again.

[0044] The first elastic element 23 not only improves the stability and durability of the tray jig 100, but also makes the first nested jig 20 smoother during use, thus enhancing the user experience.

[0045] Multiple first elastic members 23 may be provided and distributed around the bottom of the first main board 21 to provide uniform support and restoring force to the first main board 21 in the vertical direction, so as to avoid deformation or damage to the first main board 21 due to uneven force.

[0046] Meanwhile, the first elastic elements 23 distributed around the perimeter effectively improve the stability of the main board during reset, allowing the first main board 21 to rise and fall stably and accurately return to its initial position, ensuring the normal use of the fixture. Furthermore, the multiple first elastic elements 23 enhance the overall structural strength of the fixture, improving its durability and service life.

[0047] The first nested fixture 20 also includes a first limiting pin 24 disposed on the side of the first main board 21. The base 10 has a first limiting hole 12 extending in the vertical direction on its side, and the first limiting pin 24 is slidably connected in the first limiting hole 12.

[0048] During the lifting and lowering process of the first main board 21, the first limiting pin 24 slides along the first limiting hole 12. The first limiting hole 12 not only restricts the movement range of the first main board 21, but also provides it with clear guidance, allowing the main board to move smoothly along a predetermined vertical path during the compression and reset of the first elastic element 23, preventing it from shifting in the horizontal direction, thereby maintaining the accuracy and stability of the fixture. This helps to extend the service life of the fixture and ensures that it can still maintain good working condition after long-term use.

[0049] The width of the first limiting hole 12 matches the diameter of the first limiting pin 24, and the length matches the lifting stroke of the first main board 21. This allows the first limiting pin 24 to slide smoothly within the first limiting hole 12, while limiting its excessive displacement and preventing damage caused by excessive compression or stretching of the elastic element.

[0050] In this embodiment, the first limiting hole 12 is approximately elongated elliptical in shape, with its end arc-shaped to fit the first limiting pin 24. This reduces the impact and wear of the first limiting pin 24 when it slides to both ends of the limiting hole, thereby further extending the service life of the fixture.

[0051] The first limiting pin 24 is fixed to the side of the first motherboard 21, and the side of the first motherboard 21 is provided with a first insertion hole 211 for the first limiting pin 24 to be inserted.

[0052] In this embodiment, two first limiting pins 24 are provided at intervals on both the left and right sides of the first mainboard 21. Correspondingly, two first limiting holes 12 corresponding to the first limiting pins 24 are also provided at intervals on both the left and right sides of the base 10. The two first limiting pins 24 are respectively located near the side ends of the first mainboard 21 to improve the stability of the first mainboard 21 during the lifting and lowering process.

[0053] Trays are generally directional, such as having a positioning notch at any corner of the tray. The base 10 has a first positioning part 13 that mates with the positioning notch, and the first main board 21 has a second positioning part 212 that mates with the positioning notch. The first positioning part 13 and the second positioning part 212 ensure the accurate positioning of the tray in the fixture, preventing the tray from being reversed and causing directional errors during production, which could lead to component misalignment, equipment jamming, or even product scrap.

[0054] Furthermore, the tray fixture 100 also includes a second nested fixture 30 movably disposed inside the second positioning groove 22. The second nested fixture 30 includes a second main board 31, and a third positioning groove 32 is formed inside the second main board 31. The third positioning groove 32 can be used to accommodate a third-size tray 3.

[0055] When the tray jig 100 accommodates a tray 1 of a first size or a tray 2 of a second size, the second main board 31 is pressed and moves downward in the vertical direction to expose the first positioning groove 11 or the second positioning groove 22.

[0056] The second nested fixture 30 allows the tray fixture 100 to accommodate a third-sized tray 3, further increasing the versatility of the tray fixture 100 and making the fixture structure more compact.

[0057] Specifically, when a third-sized tray needs to be accommodated, the tray can be placed in the third positioning groove 32 of the second nesting fixture 30. When a first-sized tray 1 or a second-sized tray needs to be accommodated, the second main board 31 will move vertically downwards under the gravity of the tray until the first positioning groove 11 or the second positioning groove 22 is fully exposed, thus allowing the first or second-sized tray to be smoothly inserted.

[0058] Thus, the tray fixture 100 can accommodate trays of three different sizes, thereby improving its applicability and flexibility.

[0059] The second nested fixture 30 also includes a second elastic element 33, one end of which is connected to the bottom of the second main board 31, and the other end is fixed to the bottom wall of the positioning groove.

[0060] The second elastic element 33 is located between the bottom of the second main board 31 and the bottom wall of the positioning groove. It is used to push the second main board 31 to move vertically and return to the initial position after the first or second size tray 2 is removed. No manual operation is required, which can improve the automation and convenience of the fixture.

[0061] Similarly, multiple second elastic elements 33 may be provided, distributed around the bottom perimeter of the second main board 31, to ensure the smooth vertical movement of the second main board 31 and avoid jamming or tilting caused by uneven force. The provision of multiple second elastic elements 33 also enhances the durability and stability of the fixture, improves its load-bearing capacity, and enables it to stably accommodate trays of the first or second size.

[0062] The second elastic element 33 is disposed on the inner side of the base 10 near the middle region, relative to the first elastic element 23.

[0063] The second nested fixture 30 also includes a second limiting pin 34 disposed on the side of the second main board 31. The base 10 has a second limiting hole 14 extending vertically on its side. The first main board 21 has a clearance hole 213 opening towards the bottom. The second limiting pin 34 passes through the clearance hole 213 and is slidably connected to the second limiting hole 14.

[0064] During the lifting and lowering process of the second main board 31, the second limiting pin 34 slides along the second limiting hole 14. The second limiting hole 14 not only restricts the movement range of the second main board 31 but also provides clear guidance, enabling the second main board 31 to move smoothly along a predetermined vertical path during the compression and reset of the second elastic element 33, preventing it from shifting in the horizontal direction, thereby maintaining the accuracy and stability of the fixture. This helps extend the service life of the fixture and ensures that it maintains good working condition even after long-term use.

[0065] The width of the second limiting hole 14 matches the diameter of the second limiting pin 34, and the length matches the lifting stroke of the second main board 31. This allows the second limiting pin 34 to slide smoothly within the second limiting hole 14, while limiting its excessive displacement and preventing damage caused by excessive compression or stretching of the second elastic element 33.

[0066] In this embodiment, the shape of the second limiting hole 14 is the same as that of the first limiting hole 12, which is an elongated ellipse. The end is arc-shaped to fit the second limiting pin 34, which can reduce the impact and wear of the second limiting pin 34 when it slides to both ends of the second limiting hole 14, and further extend the service life of the fixture.

[0067] The second limiting pin 34 is fixed to the side of the second motherboard 31, and the side of the second motherboard 31 is provided with a second insertion hole 311 for the second limiting pin 34 to be inserted.

[0068] In this embodiment, a second limiting pin 34 is provided on each of the left and right sides and the rear side of the second main board 31. Correspondingly, a second limiting hole 14 corresponding to the second limiting pin 34 is also provided on each of the left and right sides and the rear side of the base 10. The three second limiting pins 34 are respectively provided in the middle part of the left and right sides and the rear side of the second main board 31 to improve the stability of the second main board 31 during the lifting and lowering process.

[0069] Of course, the position and number of the first and second limit pins can be adjusted according to actual needs to adapt to different sizes of trays or different installation requirements. For example, limit pins can also be added to the front side of the first main board 21 and the second main board 31, or more limit pins can be added on the basis of the existing limit pins to improve the stability and load-bearing capacity of the fixture.

[0070] Meanwhile, the shape and size of the limiting pin can also be customized as needed to ensure a tight fit with the limiting hole and avoid excessive gaps or shaking during sliding, so that the tray jig 100 can meet the needs of different users.

[0071] The second motherboard 31 also has a third positioning part 312 that cooperates with the positioning notch provided at any corner of the tray.

[0072] In addition, the base 10 has a first slot 15 that opens to the side and communicates with the first positioning slot 11; the first main board 21 has a second slot 214 corresponding to the first slot 15, and the second main board 31 has a third slot 313 corresponding to the first slot 15.

[0073] The first slot 15, the second slot 214, and the third slot 313 have the same slot length, which is less than the length of the third positioning slot 32 in that direction.

[0074] The first slot 15, the second slot 214, and the third slot 313 make it easier to assemble and disassemble the tray jig 100 by placing and removing trays. Mechanical grippers or manual handling can extend into the base 10 through these slots to grasp, place, or adjust the trays, thus improving operational efficiency. This also facilitates user maintenance and cleaning of the jig, extending its service life.

[0075] In summary, this new tray fixture allows for the compatible placement of trays of different sizes, demonstrating versatility and practicality. The movable design of the first main board enables automatic space adjustment when accommodating trays of different sizes, eliminating the need to change fixtures and saving operation time and fixture usage costs.
