Description

Technical Field

[0001] This utility model relates to the field of UV adhesive curing degree testing technology, and more specifically to a UV adhesive curing degree testing sample holder. Background Technology

[0002] A UV adhesive curing test sample holder is a device used to test the curing degree of UV adhesives. It ensures that the UV adhesive is subjected to relatively stable and controllable conditions such as light, temperature, and humidity during the test, making the test results comparable and reliable. It fixes the UV adhesive-coated sample in a specific position to prevent the sample from moving or shaking during the test, ensuring the accuracy of the test. It is used to firmly fix the UV adhesive-coated sample on the sample holder. Common fixing methods include clips, slots, and screws. For example, the sample is tightened to the frame with screws, or the sample is clamped in place by slots so that it cannot move at will.

[0003] In practical use, there are several problems with positioning samples using screws or clips: Screw positioning relies on manual tightening force, and the tightness may vary depending on the operator or the same person's repeated operations. This can cause slight positional shifts in the sample on the frame, such as tilting or height differences, resulting in inconsistent distances and angles between the sample and the UV light source. This directly affects the light intensity and uniformity received by the UV adhesive, leading to deviations in the curing degree test results. Clip positioning, on the other hand, may experience inconsistent clearances between the sample and the clip due to dimensional tolerances or wear after long-term use, resulting in slight wobbling or "not locking" the sample. The tightness of the screws also disrupts the stability of the lighting conditions. In terms of operational efficiency, screw positioning requires tightening each screw individually when loading and unloading samples. For multi-station sample racks (such as testing multiple samples simultaneously), the operation is cumbersome and time-consuming. This is especially true in scenarios where samples need to be changed frequently, such as process debugging, which will significantly reduce testing efficiency. Although buckle positioning is more convenient than screws, the "fastening / unfastening" action still requires manual operation one by one. If the buckle is too tight, extra force is required when loading and unloading, which increases operator fatigue. If it is too loose, it is necessary to repeatedly check whether it is in place, which indirectly affects efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a UV adhesive curing degree test template frame to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a UV adhesive curing degree test sample holder, including an annular plate holder, a placement groove is provided at the top center of the annular plate holder, a sliding groove is provided at the bottom of the placement groove, and limit grooves are provided at equal intervals inside the annular plate holder. A limit plate is laterally sealed and slidably connected inside the limit groove, and a connecting rod is fixedly connected to the center of the surface of the limit plate. A positioning component is installed at the end of the connecting rod away from the limit plate. A sealing cavity is provided inside the annular plate holder, and a sealing block is sealed and slidably connected inside the sealing cavity. An electric telescopic rod is fixedly installed inside the annular plate holder, and the output end of the electric telescopic rod is fixedly connected to the center of the surface of the sealing block. A vent pipe communicating with the inside of the sealing cavity is fixedly connected inside the annular plate holder, and the input end of the vent pipe is connected to the inside of the limit groove.

[0006] Furthermore, the positioning assembly includes a sealing cylinder fixedly connected to the end face of the connecting rod, a spring movably installed inside the sealing cylinder, a sealing disc longitudinally and slidably connected inside the sealing cylinder, a connecting rod fixedly connected to the top of the sealing disc, a pressure plate fixedly connected to the top of the connecting rod, a buffer plate fixedly connected to the bottom of the pressure plate, a rubber sleeve fixedly fitted onto the outer surface of the sealing cylinder, and the end of the vent pipe away from the sealing cavity fixedly connected to the bottom of the sealing cylinder and communicating with the interior of the sealing cylinder.

[0007] Furthermore, the vent pipe is a flexible hose and is movably connected inside the slide groove. Both the limiting groove and the limiting plate are square, and a sealing ring is fixedly installed on the outer surface of the limiting plate.

[0008] Furthermore, the outer surface of the annular plate frame is provided with equidistant ventilation grooves, and the end of the limiting groove away from the connecting rod is connected to the outside of the annular plate frame through the ventilation groove.

[0009] Furthermore, the outer surface of the sealing cylinder is slidably connected to the interior of the placement groove and the slide groove, and the top of the sealing cylinder extends to the upper surface of the annular plate frame.

[0010] Furthermore, a sealing ring is fixedly installed on the outer surface of the sealing disc. Under normal conditions, the sealing disc slides upward due to the elasticity of the spring. The buffer plate is a silicone ring.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model effectively solves the defects of traditional screw or buckle positioning by using a pneumatically driven synchronous positioning structure. The electric telescopic rod drives the sealing block to slide in the sealing cavity, and the generated air pressure is synchronously transmitted to multiple limiting grooves and positioning components through the air pipe, so that all positioning components move towards the center at the same time, ensuring that the sample is subjected to uniform and stable clamping force in both the horizontal and vertical directions. This synchronous driving method avoids the tightness difference caused by manual operation, reduces problems such as sample tilting and offset, and ensures that the distance and angle between the sample and the UV light source are consistent, which significantly improves the accuracy of UV adhesive curing degree test results. At the same time, the buffer plate in the positioning component is made of silicone ring material, which can not only enhance the friction on the sample, but also avoid damage to the sample surface caused by hard contact, further ensuring the stability of the test process.

[0013] 2. Compared to the traditional method of tightening screws one by one or fastening clips one by one, the pneumatic drive structure of this utility model enables rapid loading and unloading of samples. The clamping and loosening of all positioning components can be completed simultaneously by simply extending and retracting the electric telescopic rod, which greatly shortens the sample replacement time during multi-station testing. It is especially suitable for scenarios such as process debugging that require frequent sample replacement. In addition, the spring and sealing plate structure in the positioning components have a certain elastic adjustment space. Combined with the flexible contact of the rubber sleeve, it can adapt to samples of different specifications and even irregular shapes without the need to replace special clamps, thus expanding the applicability of the sample rack and improving the versatility and practicality of the equipment.

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0021] A UV adhesive curing degree test sample holder includes an annular plate holder 1. A placement groove 2 is provided at the top center of the annular plate holder 1, and a sliding groove 3 is provided at the bottom of the placement groove 2. Limiting grooves 4 are provided at equal intervals inside the annular plate holder 1. A limiting plate 5 is laterally sealed and slidably connected inside the limiting groove 4. A connecting rod 6 is fixedly connected to the center of the surface of the limiting plate 5. A positioning component 7 is installed at the end of the connecting rod 6 away from the limiting plate 5. A sealing cavity 8 is provided inside the annular plate holder 1. A sealing block 9 is slidably connected inside the sealing cavity 8. An electric telescopic rod 10 is fixedly installed inside the annular plate holder 1. The output end of the electric telescopic rod 10 is fixedly connected to the center of the surface of the sealing block 9. A vent pipe 11 is fixedly connected inside the annular plate holder 1 and communicates with the inside of the sealing cavity 8. The input end of the vent pipe 11 is connected to the inside of the limiting groove 4.

[0022] In this implementation scheme, the annular plate frame 1 drives the sealing block 9 to slide within the sealing cavity 8 via the electric telescopic rod 10. The resulting air pressure is synchronously transmitted to multiple limiting grooves 4 via the vent pipe 11, causing the limiting plate 5 to drive the positioning components 7 to move synchronously via the connecting rod 6. This achieves synchronous driving of all positioning components 7, avoiding the problem of uneven clamping force caused by differences in manual operation when using traditional screw or clip positioning. It ensures that the sample is subjected to uniform force within the placement groove 2, reduces tilting or offset, and ensures that the distance and angle between the sample and the UV light source are consistent, significantly improving test accuracy. At the same time, the connection design between the vent pipe 11 and the limiting groove 4 makes the air pressure transmission efficient and stable, further enhancing the synchronization of positioning.

[0023] Specifically, the positioning component 7 includes a sealing cylinder 71 fixedly connected to the end face of the connecting rod 6. A spring 72 is movably installed inside the sealing cylinder 71. A sealing disc 73 is longitudinally and slidably connected inside the sealing cylinder 71. A connecting rod 74 is fixedly connected to the top of the sealing disc 73. A pressure plate 75 is fixedly connected to the top of the connecting rod 74. A buffer plate 76 is fixedly connected to the bottom of the pressure plate 75. A rubber sleeve 77 is fixedly fitted onto the outer surface of the sealing cylinder 71. One end of the vent pipe 11 away from the sealing cavity 8 is fixedly connected to the bottom of the sealing cylinder 71 and communicates with the inside of the sealing cylinder 71.

[0024] In this embodiment, spring 72 provides elastic cushioning, allowing sealing disc 73 to remain in an upward sliding state under normal conditions, facilitating sample insertion. When air pressure is applied inside sealing cylinder 71, sealing disc 73 drives connecting rod 74 and pressure plate 75 to move downward, achieving longitudinal compression of the sample through buffer plate 76. The silicone buffer plate 76 increases friction with the sample to prevent slippage and avoids damage to the sample surface from hard contact. Rubber sleeve 77 enhances the lateral contact stability between sealing cylinder 71 and sample. Combined with longitudinal compression, it achieves all-round stable clamping of the sample, suitable for samples of different thicknesses, and improves positioning reliability.

[0025] Specifically, the vent pipe 11 is a flexible hose and is movably connected inside the slide groove 3. The limiting groove 4 and the limiting plate 5 are both square, and a sealing ring is fixedly installed on the outer surface of the limiting plate 5.

[0026] In this embodiment, the vent pipe 11 adopts a flexible hose design and is movably connected in the slide groove 3. It can flexibly deform as the positioning component 7 moves, avoiding pipe jamming that affects air pressure transmission. The square limiting groove 4 and the limiting plate 5 cooperate to prevent the limiting plate 5 from rotating during sliding, ensuring the stability of the lateral movement of the positioning component 7. The sealing ring on the outer surface of the limiting plate 5 enhances the sealing performance of the limiting groove 4, ensuring that the air pressure can efficiently drive the limiting plate 5 to slide, reducing the problem of insufficient driving force caused by air leakage, and improving the synchronous response speed of the positioning component 7.

[0027] Specifically, ventilation slots are provided at equal intervals on the outer surface of the annular plate frame 1, and the end of the limiting slot 4 away from the connecting rod 6 is connected to the outside of the annular plate frame 1 through the ventilation slot.

[0028] In this embodiment, the ventilation groove on the outer surface of the annular plate frame 1 allows the end of the limiting groove 4 away from the connecting rod 6 to communicate with the outside. When the limiting plate 5 slides under air pressure, the end of the limiting groove 4 away from the sliding groove 3 can quickly exhaust or enter air through the ventilation groove, avoiding the limitation plate 5 from being hindered by the air pressure difference, ensuring the smooth sliding of the positioning component 7, improving the efficiency of sample loading and unloading, and balancing the air pressure inside the limiting groove 4 to ensure the stability of the air pressure drive.

[0029] Specifically, the outer surface of the sealing cylinder 71 is slidably connected to the interior of the placement groove 2 and the slide groove 3, and the top of the sealing cylinder 71 extends to the upper surface of the annular plate frame 1.

[0030] In this embodiment, the sealing cylinder 71 is slidably connected in the placement groove 2 and the slide groove 3, and its top extends to the upper surface of the annular plate frame 1, which strictly restricts the movement trajectory of the positioning component 7, avoids lateral offset, and ensures that all positioning components 7 always point to the center of the placement groove 2, thus ensuring the concentricity of the template positioning. At the same time, the extended design of the sealing cylinder 71 facilitates the longitudinal pressing of the template by the pressure plate 75 and the buffer plate 76, making the structural layout more compact and the operation more convenient.

[0031] Specifically, a sealing ring is fixedly installed on the outer surface of the sealing disc 73. Under normal conditions, the sealing disc 73 slides upward by the elasticity of the spring 72, and the buffer plate 76 is a silicone ring.

[0032] In this embodiment, the sealing ring on the outer surface of the sealing disc 73 enhances the sealing performance of the sealing cylinder 71, ensuring that the air pressure can effectively drive the sealing disc 73 to move up and down, avoiding insufficient longitudinal clamping force caused by air leakage; under normal conditions, the spring 72 pushes the sealing disc 73 to slide upward, so that the pressure plate 75 and the buffer plate 76 are in a raised state, which facilitates the placement of the sample; the buffer plate 76 made of silicone ring material has good elasticity and wear resistance, which can not only adapt to the sample surface with different flatness, but also avoid scratching the sample when clamping, while enhancing the friction with the sample, further preventing the sample from loosening during the test.

[0033] The working principle and usage process of this utility model are as follows: During use, the sample to be tested is placed inside the placement groove 2. The electric telescopic rod 10 is activated, causing the sealing block 9 to slide to the right. At this time, the sealing cavity 8 is under negative pressure. The vent pipe 11 also creates a negative pressure at the end of the limiting groove 4 near the sliding groove 3. The limiting plate 5, through the connecting rod 6, causes all the sealing cylinders 71 to slide towards the test sample. When the surface of the rubber sleeve 77 abuts against the surface of the test sample, lateral positioning of the test sample is achieved. Due to the elasticity of the spring 72, when ventilation... When the tube 11 creates a negative pressure inside the sealing cylinder 71, the elasticity of the spring 72 prevents the sealing disc 73 from sliding down directly. When the surface of the rubber sleeve 77 presses against the surface of the test sample, the negative pressure inside the sealing cylinder 71 gradually increases, forcing the sealing disc 73 to slide down through the connecting rod 74, driving the pressure plate 75 to slide down until the bottom of the buffer plate 76 presses against the upper surface of the test sample. This directly achieves the lateral and longitudinal positioning of the test sample. Furthermore, this pneumatic positioning method can quickly adapt to different specifications and irregular samples, enabling rapid fixation.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
