Description

Technical Field

[0001] The utility model relates to the technical field of mold processing devices, in particular to a UV photosensitizer used in a mold graining process. Background Art

[0002] Texture is a common process for mold surface treatment. Mold texture is also called mold biting, mold etching and mold etching. It is widely used because of its low process cost, rich effects and fast molding speed. Correspondingly, the product made by the texture mold can form the texture corresponding to the mold. Some of these textures are used for decoration, while others belong to the structural design requirements. Therefore, the implementation effect of mold texture directly affects the surface beauty and structural design of the product.

[0003] The principles and steps of sunburn are as follows:

[0004] 1.1. First, use photos and computer technology to make a specific etching pattern film negative.

[0005] 1.2. Then stick the film onto the clean mold surface step by step, and manually correct the gaps during the sticking process.

[0006] 1.3. Next, the mold workpiece is placed under ultraviolet (UV) light for curing and developed in a prepared photographic solution.

[0007] 1.4. Then, under precise control, the mold surface will be corroded into a pattern layer with a specific depth by a certain acid according to the developed etching pattern; the whole etching process is to make an acid pool with an appropriate amount of accurately proportioned acid solution such as nitric acid or ferric chloride and then put the workpiece into the acid pool, or spray the acid directly onto the mold surface in the form of a spray. The specific etching time can be selected according to different etching depths or pattern complexity, and the etching depth is usually between 0.1-0.5mm.

[0008] 1.5. In addition, many etched patterns on the surface of molds are made by multiple etchings or multi-layer etched pattern films, which requires multiple etching steps and a combination of multiple special pattern films to achieve.

[0009] Among them, the curing process of placing the mold workpiece under the ultraviolet curing lamp is currently mainly done by the operator holding the UV curing lamp to irradiate the photosensitive ink, which cannot effectively protect the mold workpiece and is also easy to cause damage to the operator's eyes. In addition, in the current operation method, the specific control factors such as irradiation distance and irradiation time are basically based on personal experience, which makes it difficult to control the standardization of the operation, resulting in differences in status during the operation, and it is difficult to ensure the consistency of the production status.

DETAILED DESCRIPTION

[0040] The following is an explanation and description of the technical solution of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiments are only preferred embodiments of the utility model, not all; and under the premise that the technical solutions do not conflict, the technical means of each embodiment can be reasonably and freely combined. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making creative work are all within the protection scope of the utility model.

[0041] In the description of the present utility model, it needs to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships that are based on the orientations or relative positional relationships shown in the accompanying drawings, and are intended to facilitate a clear description of the structure of a product or device, and are not used to limit the actual orientation of the product or device during production, use, sales, and the like.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more, unless otherwise clearly defined.

[0043] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "set", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0045] This embodiment provides a UV photosensitive device, which is used in the implementation of the ultraviolet photosensitive curing process in the mold grain processing process, and is intended to improve the efficiency of the curing process of the mold workpiece through ultraviolet light irradiation. Figure 1 , Figure 2 and Figure 3 As shown, the UV photosensitive device provided in this embodiment includes: a UV protective cover 10, a UV irradiation module 20 and a workpiece carrier 30; the UV protective cover 10 has an openable and closable side door 11; the UV irradiation module 20 is arranged in the UV protective cover 10; the workpiece carrier 30 is pulled out of or pushed into the UV protective cover 10 through the side door.

[0046] Among them, the UV protective cover 10 is made of ultraviolet-proof material and has a certain accommodating space inside; the workpiece carrying platform 30 is used to carry the workpiece to be UV-sensitive and send the workpiece into the UV protective cover 10; the UV irradiation module 20 is used to perform ultraviolet irradiation on the workpiece sent into the UV protective cover 10.

[0047] Specifically, when the workpiece carrier 30 is pulled out of the UV protective cover 10 through the side door 11, the staff or the automatic transfer mechanism places the workpiece to be UV-exposed on the workpiece carrier 30, and then pushes the workpiece carrier 30 into the UV protective cover 10, and closes the side door 11; then the UV irradiation module 20 is turned on to irradiate the workpiece in the UV protective cover 10. In this way, during the irradiation process, the UV protective cover 10 can not only protect the workpiece inside (for example, dustproof), but also protect the staff outside from ultraviolet rays; moreover, the workpiece to be UV-exposed can be conveniently moved into the UV protective cover 10 and the UV-exposed workpiece can be moved out of the UV protective cover 10 through the workpiece carrier 30.

[0048] In one implementation of this embodiment, the UV irradiation module 20 is adjustably disposed in the UV protective cover 10 through a position adjustment mechanism 40. In the above preferred embodiment, the UV irradiation module is set to be position-adjustable through the position adjustment mechanism, so that the UV irradiation module can better adapt to various types of workpieces pushed into the UV protective cover 10; for example, workpieces of different thicknesses will have different heights when placed on the workpiece carrier, or the workpiece placed on the workpiece carrier cannot be placed in the center, so these differences can be accommodated by adjusting the position of the UV irradiation module. It is understandable that the UV irradiation module 20 can also be fixedly disposed in the UV protective cover 10, so that it can also adapt to the same type of mold workpieces.

[0049] In addition, the UV photosensitive device provided in this embodiment further includes a distance detection module 50, which is used to detect the relative distance between the UV irradiation module 20 and the workpiece to be UV-sensitive on the carrier. In this embodiment, the distance detection module detects the distance between the workpiece to be UV-sensitive on the carrier and the UV irradiation module, which can provide a reference for adjusting the appropriate position of the UV irradiation module 20.

[0050] Specifically, the distance detection module 50 is a light-sensing distance detection module, such as a photoelectric sensing module based on the principle of light reflection. In this embodiment, the distance detection module 50 is integrated with the UV irradiation module 20, or is arranged adjacent to the UV irradiation module 20 on the position adjustment mechanism 40. In this way, by arranging the distance detection module 50 and the UV irradiation module 20 as one or adjacent to each other, the distance detected by the distance detection module 50 can most closely represent the position of the UV irradiation module 20, providing a more accurate reference for adjusting the specific position of the UV irradiation module. It is understandable that the distance detection module 50 can also be a distance detection module based on the principle of metal detection, or a distance detection module based on image analysis.

[0051] See also Figure 3As shown, the UV photosensitive device provided in this embodiment also includes a UV energy detector 60, which is arranged in the UV protective cover 10. By setting the UV energy detector 60, the energy intensity of the UV irradiation module 20 can be detected in advance, providing a reference for the position adjustment of the UV irradiation module 20 and the adjustment of its own power level; at the same time, it can also provide a reference for the irradiation time of the specific irradiation operation process of the workpiece.

[0052] In addition, the UV photosensitive device provided in this embodiment further includes a light shielding plate 70, which is disposed at the lower part of the UV protective cover 10 and divides the lower part of the UV protective cover into a carrier accommodating chamber 101 and a detector accommodating chamber 102. Figure 3 As shown. The UV energy detector 60 is disposed in the detector accommodating cavity 102, and the workpiece carrier 30 pushed into the UV protective cover is located in the carrier accommodating cavity 101. In this embodiment, by disposing a light baffle 70 at the lower part of the UV protective cover 10, and dividing the lower part of the UV protective cover 10 into the carrier accommodating cavity 101 and the detector accommodating cavity 102, the UV energy detector 60 can pre-detect the energy intensity of the UV irradiation module 20 in a light-shielding space (detector accommodating cavity 102) without affecting the workpiece in the carrier accommodating cavity 101; at the same time, the undivided space in the upper part of the UV protective cover 10 facilitates the displacement and switching of the UV irradiation module between the carrier accommodating cavity 101 and the detector accommodating cavity 102 (wherein, Figure 3 The UV irradiation module 20 shown by the middle dotted line is a schematic diagram of the UV irradiation module 20 being displaced into the detector accommodating cavity 102).

[0053] Continue to see Figure 2 As an implementation mode, the workpiece carrier 30 includes a carrier plate 31 and a sliding member 32, and the carrier plate 31 is fixedly arranged on the sliding member 32; at the same time, a slide groove is arranged at the bottom of the UV protective cover 10, and the sliding member 32 cooperates with the slide groove so that the carrier plate 31 can be pulled out or pushed into the UV protective cover 10 through the side door 11.

[0054] In addition, the workpiece carrier 30 also includes a driving component (not shown in the figure), which can be a motor and a gear set. A rack is arranged on the sliding member 32. The motor gear set is engaged with the rack, so that the sliding member 32 and the carrier plate 31 can be driven to slide automatically along the slide groove. In this embodiment, the driving component drives the sliding member to slide automatically along the slide groove, so that the workpiece carrier 30 can be automatically pulled out of the UV protective cover 10 so that the staff can load the material (i.e., place the workpiece to be UV-sensitive); it can also be automatically pushed into the UV protective cover 10 for UV-sensitive operation, which greatly improves production efficiency.

[0055] Continue to see Figure 2 and Figure 3The position adjustment mechanism 40 mentioned above includes an X-direction linear drive module 41, a Z-direction linear drive module 42 and a Y-direction linear drive module 43; the distance detection module 50 and the UV irradiation module 20 are movably arranged on the X-direction linear drive module 41 along the X-direction, the X-direction linear drive module 41 is movably arranged on the Z-direction linear drive module 42 along the Z-direction, the Z-direction linear drive module 42 is movably arranged on the Y-direction linear drive module 43 along the Y-direction, and the Y-direction linear drive module 43 is fixedly arranged on the inner side wall of the UV protective cover 10 along the Y-direction.

[0056] It is understandable that the position adjustment mechanism 40 can also be a multi-axis robot, and the distance detection module 50 and the UV irradiation module 20 are arranged at the free drive end of the multi-axis robot. Regardless of the cooperation of the multi-axis robot or the X\Y\Z three-way linear drive module, the distance detection module and the UV irradiation module 20 can be quickly and accurately adjusted to the desired position, and at the same time, according to the detection signal of the distance detection module 50, the position of the distance detection module 50 and the UV irradiation module 20 can be further corrected and fine-tuned.

[0057] Continue to see Figure 1 The UV photosensitive device provided in this embodiment also includes a main control module 90, which is electrically connected to the UV irradiation module 20, the distance detection module 50, the position adjustment mechanism 40, the UV energy detector 60, and the driving component; the main control module 90 includes a display panel, an input case and a PLC control component, which controls the above modules and mechanisms to automatically cooperate and operate, making the device more intelligent and automated.

[0058] The above embodiments are only intended to fully disclose but not limit the present invention. Any replacement of equivalent technical features based on the creative purpose of the present invention without creative labor should be regarded as the scope disclosed in this application.
