Description

Technical Field

[0001] This utility model relates to the field of OCA optical adhesive curing technology, specifically to an OCA optical adhesive curing irradiation box. Background Technology

[0002] The OCA optical adhesive curing irradiation box is a device used for curing optical adhesives. OCA optical adhesives are commonly used in the display panels of electronic products (such as mobile phones, tablets, and TV displays) as adhesive materials for screen components. They have excellent transparency and optical properties. OCA optical adhesives need to be cured under certain light conditions to ensure their bonding performance and stability.

[0003] For example, application number 202222337808.1 describes an OCA optical adhesive curing irradiation box. The user conveniently places the raw material inside the placement box, and then the two placement boxes move in a cycle driven by a motor. When one placement box engages with the irradiation box body, the other placement box will be located next to the user, allowing the user to load or unload the material. This forms a cyclical alternating loading and unloading operation. In conjunction with the ultraviolet drying lamp and air heater, the processing efficiency of the raw material is greatly improved, making it simpler and more convenient.

[0004] It has the following disadvantages:

[0005] The placement box rotates continuously, so when the placement box passes the irradiation box body, the irradiation time of the object placed inside the placement box body is relatively short. This can easily lead to a problem where the OCA optical adhesive on the object surface is not firmly bonded to the object.

[0006] Therefore, we propose an OCA optical adhesive curing irradiation box. Utility Model Content

[0007] One of the technical problems to be solved in this application is: how to design an OCA optical adhesive curing irradiation box that can improve the bond between the object and the OCA optical adhesive.

[0008] To address the aforementioned technical problems, this application provides an OCA optical adhesive curing irradiation box, comprising a worktable, a turntable rotatably mounted on the upper surface of the worktable, a plurality of placement boxes disposed on the upper surface of the turntable, a support frame disposed on one side of the turntable, an irradiation box disposed on the lower surface of the support frame, and a drive assembly disposed on the lower surface of the worktable, the drive assembly being used to drive the turntable to rotate intermittently.

[0009] In some embodiments, the drive assembly includes a drive wheel and a driven wheel rotatably connected to the lower end face of the worktable. The driven wheel is connected to the turntable. The drive wheel has a groove that is arc-shaped and a fixing protrusion is provided inside the groove. The driven wheel has multiple slots and the fixing protrusion is engaged in one of the slots.

[0010] In some embodiments, an arc-shaped groove is formed between two adjacent slots, and the lower end face of the driven wheel is attached to the groove on the driving wheel.

[0011] In some embodiments, a protective box is provided below the drive wheel, the protective box is connected to the worktable, the drive wheel and the driven wheel are located inside the protective box, a servo motor is provided on the protective box, and the output end of the servo motor is connected to the drive wheel.

[0012] In some embodiments, a buffer assembly is provided at the bottom inner side of the placement box. The buffer assembly is used to buffer the inertial impact force of the irradiated object placed inside the placement box falling. The buffer assembly includes a support plate and a silicone pad disposed inside the placement box. The silicone pad is connected to the upper end face of the support plate.

[0013] In some embodiments, a plurality of helical springs are connected to the lower end face of the support plate, and the end of the helical springs away from the support plate is connected to the bottom end of the inner side of the placement box.

[0014] In some embodiments, the size of the irradiation chamber is adapted to the size of the placement box, and a start / stop sensor is provided on one side of the lower end face of the irradiation chamber.

[0015] This utility model has at least the following beneficial effects:

[0016] By setting the drive component, the placement box on the turntable can be rotated intermittently. This not only extends the irradiation time of the object inside the placement box, thereby improving the bonding strength between the OCA optical adhesive on the object and the object, but also allows time for loading and unloading of the object inside the placement box, making the loading and unloading of the object inside the placement box more stable.

Detailed Implementation

[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1 and 2 This utility model provides a technical solution:

[0026] An OCA optical adhesive curing irradiation box includes a workbench 1, a turntable 2 rotatably mounted on the upper surface of the workbench 1, a plurality of placement boxes 3 disposed on the upper surface of the turntable 2, a support frame 4 disposed on one side of the turntable 2, an irradiation box body 5 disposed on the lower surface of the support frame 4, and a drive assembly 6 disposed on the lower surface of the workbench 1, the drive assembly 6 being used to drive the turntable 2 to rotate intermittently.

[0027] Please see Figure 3 and Figure 4 The drive assembly 6 includes a drive wheel 61 and a driven wheel 62 rotatably connected to the lower end face of the worktable 1. The driven wheel 62 is connected to the turntable 2. The drive wheel 61 has a groove 63, which is arc-shaped. A fixing protrusion 64 is provided inside the groove 63. The driven wheel 62 has multiple slots 65, and the fixing protrusion 64 is engaged in one of the slots 65.

[0028] An arc-shaped groove 66 is provided between two adjacent slots 65, and the lower end face of the driven wheel 62 is attached to the groove 63 on the driving wheel 61.

[0029] The driving wheel 61 is tangent to the arc-shaped groove 66 on the driven wheel 62, and the diameters of the driving wheel 61 and the driven wheel 62 are matched.

[0030] A protective box 67 is provided below the drive wheel 61. The protective box 67 is connected to the workbench 1. The drive wheel 61 and the driven wheel 62 are located inside the protective box 67. A servo motor 68 is provided on the protective box 67. The output end of the servo motor 68 is connected to the drive wheel 61.

[0031] In use, the object to be irradiated is placed in an empty placement box 3, and then the servo motor 68 is started. The servo motor 68 drives the drive wheel 61 to rotate, the drive wheel 61 drives the fixed protrusion 64 to rotate, the rotation of the fixed protrusion 64 drives the driven wheel 62 to rotate, the driven wheel 62 drives the turntable 2 to rotate, and the turntable 2 drives the placement box 3 on which the object to be irradiated is placed to rotate towards the irradiation chamber 5. When the fixed protrusion 64 on the drive wheel 61 rotates out of the slot 65 on the driven wheel 62, an arc-shaped groove 66 on the driven wheel 62 is attached to the drive wheel 61. At this time, Driven wheel 62 and turntable 2 stop rotating. A placement box 3 containing the object to be irradiated is located below the irradiation box 5. The irradiation box 5 irradiates the object inside the placement box 3. When the fixed protrusion 64 on the drive wheel 61 rotates to an adjacent slot 65 on the driven wheel 62, the turntable 2 rotates in the same way as the above steps. At this time, the placement box 3 adjacent to the irradiated object placement box 3 rotates to the bottom of the irradiation box 5. Then, the irradiated object inside the placement box 3 is taken out, and then the object to be irradiated is placed in the empty placement box 3. This process is repeated.

[0032] The drive component 6 can drive the placement box 3 on the turntable 2 to rotate intermittently. This not only extends the irradiation time of the object inside the placement box 3, thereby improving the bonding strength between the OCA optical adhesive on the object and the object, but also allows time for loading and unloading of the object inside the placement box 3, making the loading and unloading of the object inside the placement box 3 more stable.

[0033] The size of the irradiation box 5 is adapted to the size of the placement box 3, and a start / stop sensor 8 is provided on one side of the lower end face of the irradiation box 5.

[0034] The start / stop sensor 8 enables the placement box 3 to start automatically when it is moved under the irradiation box 5, and to stop automatically when the placement box 3 is misaligned with the irradiation box 5, thus preventing the light source of the irradiation box 5 from leaking out.

[0035] Example 2: Please refer to Figure 5 Based on Embodiment 1, this utility model provides a technical solution for a buffer component 7:

[0036] A buffer assembly 7 is provided at the bottom inner side of the placement box 3. The buffer assembly 7 is used to buffer the inertial impact force of the irradiated object placed inside the placement box 3 falling. The buffer assembly 7 includes a support plate 72 and a silicone pad 73 disposed inside the placement box 3. The silicone pad 73 is connected to the upper end face of the support plate 72.

[0037] The lower end face of the support plate 72 is connected to a plurality of helical springs 71, and the end of the helical spring 71 away from the support plate 72 is connected to the bottom of the inner side of the placement box 3.

[0038] When the object to be irradiated is placed inside the placement box 3, the object first comes into contact with the silicone pad 73 inside the placement box 3. If the inertia of the object falling is large, the silicone pad 73 will be driven by the force to move the support plate 72 towards the bottom of the placement box 3. The movement of the support plate 72 will compress the helical spring 71 on the lower end of the support plate 72. The helical spring 71 will be compressed by the force, thereby relieving the inertial impact force on the silicone pad 73.

[0039] The buffer component 7 can buffer the inertial impact force of the irradiated object placed inside the placement box 3 as it falls, thus protecting the irradiated object placed inside the placement box 3.
