[0001] This utility model relates to the field of prism tray technology, and in particular to a trapezoidal prism tray. Background Technology
[0002] Trapezoidal prisms are an important component of optical systems, and different surfaces require printing processes to achieve varying optical performance. Therefore, how to place and secure the prisms during their production, processing, transportation, and storage becomes a crucial issue.
[0003] Traditional prisms need to be placed on a tray or fixture for baking after one side is printed. Frequent loading, unloading, and flipping of the prism can easily cause it to collide with the tray or fixture during the loading and unloading process, thus contaminating the printed surface and resulting in low production yield.
[0004] Therefore, there is an urgent need in this field for a new type of trapezoidal prism tray to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a trapezoidal prism tray to solve the problems existing in the prior art, reduce the risk of contaminating the surface of the prism printing, and thus improve the production yield.
[0006] To achieve the above objectives, this utility model provides the following solution:
[0007] This utility model discloses a trapezoidal prism tray, including a tray body, the upper surface of the tray body is the front of the tray, the lower surface of the tray body is the back of the tray, and a plurality of prism positioning grooves are provided on the front of the tray, the prism positioning grooves are used to place trapezoidal prisms.
[0008] The first surface of the prism positioning groove is provided with a clearance surface and two support surfaces. The two support surfaces are respectively disposed on both sides of the clearance surface. When the trapezoidal prism is placed in the prism positioning groove, the two support surfaces are used to support the two long sides of the lower surface of the prism positioning groove. The second surface of the prism positioning groove is disposed opposite to the first surface of the prism positioning groove. The second surface of the prism positioning groove is a limiting surface. When the trapezoidal prism is placed in the prism positioning groove, the limiting surface abuts against one short side of the lower surface of the trapezoidal prism. The bottom surface of the prism positioning groove is provided with a support structure. When the trapezoidal prism is placed in the prism positioning groove, the support structure is used to support one short side of the lower surface of the trapezoidal prism.
[0009] Preferably, there is an included angle between the clearance surface and the support surface.
[0010] Preferably, the included angle is 25°.
[0011] Preferably, the support structure is a support column.
[0012] Preferably, each side of the limiting surface is provided with an end clearance groove.
[0013] Preferably, the prism positioning groove is further provided with a third surface and a fourth surface, the third surface and the fourth surface in the prism positioning groove are arranged opposite to each other, and each of the third surface and the fourth surface in the prism positioning groove is provided with a limiting protrusion.
[0014] Preferably, the back of the material tray is provided with multiple prism clearance slots.
[0015] Preferably, all the prism positioning slots on the front of the tray and all the prism clearance slots on the back of the tray are arranged in a rectangular array.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The purpose of this invention is to provide a trapezoidal prism tray to solve the problems existing in the prior art, reduce the risk of contaminating the surface of the prism printing, and thus improve the production yield.
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] like Figures 1-4 As shown, this embodiment provides a trapezoidal prism tray 100, including a tray body, which is a rectangular block structure. The upper surface of the tray body is the tray front 1, and the lower surface of the tray body is the tray back 2. The tray front 1 is provided with a plurality of prism positioning slots 3, each prism positioning slot 3 for placing a trapezoidal prism 11. The trapezoidal prism 11 is a common optical component, which includes an upper surface, a lower surface, a front surface, a back surface, and two side surfaces. The upper surface is a smaller rectangular surface, the lower surface is a larger rectangular surface, the front and back surfaces are trapezoidal structures with the same area (generally isosceles trapezoids), and the two side surfaces are inclined rectangular surfaces.
[0030] Regarding the specific structure inside the prism positioning groove 3, such as Figure 1 and Figure 4As shown, the inner wall of the prism positioning groove 3 has four surfaces. The first surface of the prism positioning groove 3 has a clearance surface 4 and two support surfaces 5. The two support surfaces 5 are respectively located on both sides of the clearance surface 4. When the trapezoidal prism 11 is placed in the prism positioning groove 3, the two support surfaces 5 are used to support the two long sides of the lower surface of the prism positioning groove 3. The clearance surface 4 is parallel to the lower surface of the trapezoidal prism 11 and does not contact it. The second surface of the prism positioning groove 3 is opposite to the first surface of the prism positioning groove 3. The second surface of the prism positioning groove 3 is a limiting surface 12. When the trapezoidal prism 11 is placed in the prism positioning groove 3, as shown... Figure 4 As shown, the limiting surface 12 abuts against a short side (specifically, the lower short side) of the lower surface of the trapezoidal prism 11, thereby limiting the horizontal direction of the trapezoidal prism 11. The bottom surface of the prism positioning groove 3 is provided with a support structure. When the trapezoidal prism 11 is placed in the prism positioning groove 3, the support structure supports the abutment of a short side (specifically, the lower short side) of the lower surface of the trapezoidal prism 11, thereby providing a vertically upward supporting force for the trapezoidal prism 11.
[0031] When placing the trapezoidal prism 11 into the prism positioning slot 3, only the lower surface of the trapezoidal prism 11 needs to be placed in a direction parallel to the clearance surface 4. During placement, the two long sides of the lower surface of the trapezoidal prism 11 are in line contact with the two support surfaces 5 respectively. When the trapezoidal prism 11 is placed at the bottom of the prism positioning slot 3, the limiting surface 12 abuts against the lower short side of the trapezoidal prism 11 and is in line contact, thus limiting its horizontal direction. The support structure abuts against the lower short side of the trapezoidal prism 11 and is in line contact, thus providing vertical upward support for the trapezoidal prism 11. In the prism positioning slot 3, the trapezoidal prism 11 is in line contact with all parts of the prism positioning slot 3 rather than surface contact. Reducing the contact area between the tray body and the trapezoidal prism 11 can effectively reduce the probability of contamination of the trapezoidal prism 11, thereby improving the production yield of the trapezoidal prism 11.
[0032] In this embodiment, in order to ensure that the clearance surface 4 does not contact the lower surface of the trapezoidal prism 11 when the supporting surface 5 is on the long side of the lower surface of the trapezoidal prism 11, there needs to be a certain angle between the clearance surface 4 and the supporting surface 5. In this way, the clearance surface 4 and the supporting surface 5 are not on the same plane. Therefore, when the supporting surface 5 is on the lower surface of the trapezoidal prism 11, there will be a certain gap between the clearance surface 4 and the lower surface of the trapezoidal prism 11, thereby forming a clearance effect, avoiding contact and friction between the clearance surface 4 and the trapezoidal prism 11, and ensuring the cleanliness of the lower surface of the trapezoidal prism 11.
[0033] In this embodiment, the included angle includes, but is not limited to, 25°. Those skilled in the art can also adjust the included angle appropriately by adjusting the distance between the two support surfaces 5 and the size of the trapezoidal prism 11, and are not limited to this one method.
[0034] In this embodiment, the support structure is a support column 9, which is fixed in a vertical through groove between the lower end of the clearance surface 4 and the lower end of the limiting surface 12. The axial direction of the support column 9 is perpendicular to the lower short side of the trapezoidal prism 11, thereby reducing its contact area with the trapezoidal prism 11. Furthermore, the support column 9 ensures that the trapezoidal prism 11 will not fall out of the bottom of the prism positioning groove 3 due to vibration or collision, thus improving the stability of the trapezoidal prism 11 production.
[0035] In this embodiment, each side of the limiting surface 12 is provided with an end clearance groove 10. From the top view of the main body of the tray, the end clearance groove 10 is a vertical through groove with a semi-circular cross-section. When the trapezoidal prism 11 is placed into the prism positioning groove 3, the two ends of the trapezoidal prism 11 at the bottom correspond to the two end clearance grooves 10. The purpose of this arrangement is to create clearance at the two ends of the trapezoidal prism 11 at the bottom, so as to avoid the problem of corner or edge chipping when placing the trapezoidal prism 11.
[0036] In this embodiment, the prism positioning groove 3 is further provided with a third surface and a fourth surface. The third surface and the fourth surface in the prism positioning groove 3 are arranged opposite to each other and parallel to each other. Both sides of the third surface and the fourth surface in the prism positioning groove 3 are the first surface and the second surface in the prism positioning groove 3. A limiting protrusion 6 is provided on both the third surface and the fourth surface in the prism positioning groove 3. When the trapezoidal prism 11 is placed in the prism positioning groove 3, the two limiting protrusions 6 are respectively adjacent to the front and rear of the trapezoidal prism 11 with a certain gap. The function of providing the limiting protrusions 6 is to reduce the shaking amplitude of the trapezoidal prism 11 during placement and transportation, reduce scratches caused by shaking, and improve the stability and safety of the trapezoidal prism 11 during placement. Furthermore, the front and rear of the trapezoidal prism 11 are generally not printed with ink, so there is no need to worry about contamination caused by contact between the front and rear of the trapezoidal prism 11 and the corresponding limiting protrusions 6.
[0037] In this embodiment, the back side 2 of the material tray is provided with multiple prism clearance slots 8. In actual use, multiple material trays are generally stacked sequentially from bottom to top. Figure 4 As shown, when the trapezoidal prism 11 is placed in the prism positioning groove 3, a portion of the upper end of the trapezoidal prism 11 will be higher than the front surface 1 of the tray. Therefore, the lower surface of the tray body above it (i.e., the back surface 2 of the tray) needs to be provided with a corresponding prism clearance groove 8 so that the upper end of the lower trapezoidal prism 11 extends into the upper prism clearance groove 8, thereby preventing the upper end of the trapezoidal prism 11 from contacting the tray body above it.
[0038] In this embodiment, as Figures 1-2 As shown, all the prism positioning slots 3 on the front side 1 of the material tray and all the prism clearance slots 8 on the back side 2 of the material tray are arranged in a rectangular array. And as... Figure 3 As shown, the number of prism positioning slots 3 and prism clearance slots 8 are the same and their positions correspond one-to-one. It should be noted that since the trapezoidal prism 11 is placed at an angle, the prism clearance slot 8 is located diagonally below the corresponding prism positioning slot 3 rather than directly below it.
[0039] In this embodiment, a back groove 7 is provided on each of the four sides of the back side 2 of the material tray. The purpose is to facilitate the gripper to pick up the material tray when multiple material tray bodies are stacked on the machine. In addition, the back groove 7 can reduce the thickness of the material tray body, ensuring the flatness of the material tray and preventing shrinkage during production (thicker material trays have poor flatness during production). At the same time, it can also prevent the upper surface of the trapezoidal prism 11 located below it from being exposed, ensuring the cleanliness of the trapezoidal prism 11.
[0040] In this embodiment, the material of the tray body is polyphenylene oxide (PPO) or polyether ether ketone (PEEK), both of which have high hardness and high temperature resistance. These properties are beneficial for the trapezoidal prism 11 product to be printed with ink (the purpose of printing ink is to reduce stray light) and then placed back into the tray body for high-temperature baking and curing.
