Abstract
Description
Technical Field
[0001] This utility model relates to the field of UV curing technology, specifically to a UV curing device for a vacuum chamber. Background Technology
[0002] In existing technologies, UV curing is performed outside a vacuum chamber. After the product is bonded, the chamber must be opened, and then the product is transferred to a UV lamp for curing or the UV lamp is transferred above the product for curing.
[0003] Existing curing methods have the following shortcomings:
[0004] 1. It cannot be cured in a vacuum environment, and it cannot be cured while the attachment head is in a bonded state. As the Panasonic product loses the adhesion of the attachment head, the product's gravity directly squeezes the adhesive downwards, making it difficult to guarantee the adhesive thickness.
[0005] 2. Since the vacuum chamber needs to be opened, the vacuum environment will be disrupted, causing airflow disturbances around the product and potentially leading to product displacement.
[0006] 3. While extending the vacuum breaking time can alleviate product displacement in existing UV curing methods, it also affects processing efficiency.
[0007] Therefore, it is necessary to improve existing UV curing equipment. Utility Model Content

[0009] To solve the above-mentioned technical problems, this utility model provides the following solution: A UV curing device for a vacuum chamber, comprising:
[0010] The base has a groove on its upper plate, and a step on the edge of the groove. The step has a first groove on its tread surface. Multiple cable routing holes are distributed on the bottom surface of the groove, and each cable routing hole has a second groove surrounding it.
[0011] The first sealing ring is embedded in the first groove;
[0012] The second sealing ring is provided in multiple parts, and the multiple second sealing rings are embedded in multiple second grooves one to one;
[0013] Multiple LED light panels are placed one-to-one in multiple wiring avoidance holes and pressed against the second sealing ring;
[0014] A transparent plate is placed over the step of the slot and locked to the base by a locking member. The transparent plate is pressed against the first sealing ring and forms a vacuum cavity between itself and multiple LED light panels.
[0015] Multiple air connectors are connected to the side of the base, and the multiple air connectors communicate with the vacuum chamber through air passages.
[0016] Furthermore, the upper corners of each edge of the transparent plate are chamfered;
[0017] The locking element has a chamfered angle that engages with the chamfer, and it locks onto the edge of the upper plate of the base.
[0018] Furthermore, the transparent plate is a quartz transparent plate.
[0019] Furthermore, the transparent quartz plate has multiple adsorption holes that penetrate both sides, and these adsorption holes communicate with the vacuum cavity.
[0020] Furthermore, the LED light panel is a UV light panel capable of emitting ultraviolet light, with its UV lamp beads facing the transparent panel.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. This utility model designs the platform as a UV curing device, which can cure adhesive without moving the product.
[0023] 2. This utility model can be installed as a whole into a vacuum chamber. When the attachment head reaches the bonding position, it can be directly cured, effectively ensuring the thickness of the adhesive after the product is bonded. At the same time, it avoids the influence of the vacuum airflow in the chamber, and can better ensure the positional accuracy of the product. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0033] Example 1: The specific structure of this utility model is as follows:
[0034] Please refer to the appendix. Figure 1-6 The present invention provides a UV curing device for a vacuum chamber, comprising a base 1, a first sealing ring 5, a second sealing ring 6, multiple LED light panels 4, a transparent plate 2, and multiple air connectors 7.
[0035] The base 1 is a rectangular plate with a groove on its upper surface. The groove has a step at its edge, and the step has a first groove around its tread. The bottom surface of the groove has multiple wiring avoidance holes 8, and each wiring avoidance hole 8 is equipped with a cable 10, which is electrically connected to the corresponding LED light board 4.
[0036] Each trace avoidance hole 8 has a second groove around its edge that surrounds the trace avoidance hole 8, such as Figure 2 As shown, there are four trace avoidance holes 8, and four corresponding second slots. The trace avoidance holes 8 are rectangular in structure, and correspondingly, each second slot is also rectangular in structure.
[0037] The first sealing ring 5 is embedded in the first groove, and multiple second sealing rings 6 are provided, with each of the multiple second sealing rings 6 being embedded in one of the multiple second grooves; for example Figure 2 As shown, there are four second sealing rings 6.
[0038] Multiple LED light panels 4 are placed one-to-one in multiple wiring avoidance holes and pressed against the second sealing ring 6. The upper space of the multiple LED light panels 4 is separated from the wiring avoidance holes 8.
[0039] The transparent plate 2 covers the stepped area of the slot and is locked to the base 1 by the locking member 3. The transparent plate 2 is pressed against the first sealing ring 5 and forms a vacuum cavity between itself and the multiple LED light panels 4. The upper corners of each edge of the transparent plate 2 are chamfered 21. The locking member 3 has an angle that matches the chamfer and is locked to the upper edge of the base 1. The transparent plate 2 is a quartz transparent plate. The quartz transparent plate has multiple adsorption holes that penetrate both sides and communicate with the vacuum cavity.
[0040] Multiple air connectors 7 are connected to the side of the base 1, and the multiple air connectors 7 communicate with the vacuum chamber through air passages 9. When the product is placed into the surface of the quartz transparent plate through the attachment head, the multiple air connectors 7 draw air outward, creating a negative pressure in the vacuum chamber, causing the product to adhere tightly to the surface of the quartz transparent plate.
[0041] The LED light panel 4 is a UV light panel that emits ultraviolet light, with its UV lamp beads facing the transparent panel 2. When the product is attracted, the UV light panel is powered on, allowing the adhesive to cure quickly.
[0042] In summary, this utility model designs the stage as a UV curing device, which can cure without moving the product. This design successfully achieves curing inside the vacuum chamber. The entire stage can be placed completely in the vacuum chamber. When the attachment head reaches the bonding position, it can be directly cured, effectively ensuring the thickness of the adhesive after the product is bonded. At the same time, it avoids the influence of the vacuum gas flow in the chamber, which can better ensure the positional accuracy of the product bonding.
[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
