Description

Technical Field

[0001] This utility model relates to a pressing device based on a UV light source, belonging to the field of industrial manufacturing equipment technology. Background Technology

[0002] UV adhesives are commonly used for bonding the casings of electronic devices, medical devices, and other equipment. Current technology typically employs simple molds for mechanical pressing, followed by UV curing under UV light to complete the bonding. However, this UV adhesive bonding method has certain technical drawbacks: Mechanical pressing of the outer shell, especially when done manually, is prone to uneven or excessive force, leading to uneven adhesive layer thickness or localized damage and defective products. This method of first mechanically pressing and then UV curing prevents simultaneous pressing and curing, increasing process changeover time and causing stress defects in the adhesive layer due to excessively long intervals between pressing and curing. Therefore, existing technology has shortcomings and requires further improvement and refinement. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pressing device based on a UV light source, which is suitable for assembly scenarios that require UV curing, such as electronic components, medical devices, and optical devices.

[0004] According to an embodiment of this utility model, the first embodiment is provided as: a pressing device based on a UV light source, comprising: A pressing assembly, the pressing assembly including a displacement control mechanism, a pressing plate body and at least one contour pressing block disposed on the pressing plate body; A movable contouring base, comprising a base body and a movable guide rail, wherein the base body is provided with at least one pressing station adapted to the contouring pressure block, and one or a group of dispensing products can be fixed at each pressing station. Driven by the displacement control mechanism, the pressure plate moves toward the base body and completes the pressing operation on the glued product at the pressing station. The base body can be moved along the moving guide rail to the pressing position to complete the pressing operation. When the base body is in the pressing position, it is within the irradiation range of the UV light irradiation component. When the base body leaves the pressing position, it leaves the irradiation range of the UV light irradiation component.

[0005] Furthermore, it also includes a housing that encloses the pressing assembly, the movable contour base, and the UV light irradiation assembly to prevent UV light from leaking out of the housing.

[0006] Furthermore, the housing is equipped with an automatic switch mechanism, which disconnects the circuit of the UV light irradiation component when the housing is opened.

[0007] Furthermore, when the pressing component and the base body are in the pressing position, they form a closed space, and the UV light irradiation component is set in the closed space and sequentially completes the UV curing operation.

[0008] Furthermore, the displacement control mechanism includes a support block, a control dual cylinder and a valve switch. The pressure plate body is connected to the control dual cylinder. The control dual cylinder controls the pressure plate body to move downwards from the support block to the pressing position to complete the pressing operation of the dispensing product.

[0009] Furthermore, it also includes a base; the moving guide rail of the movable contour base is set on the upper plane of the base; the support block of the pressing component is fixed on the support frame of the base, and the control double cylinder is vertically arranged above the plane of the base and controls the vertical direction of the pressing plate body; the UV light irradiation component is set below the base body.

[0010] Furthermore, the air valve switch is located on the outer wall of the base.

[0011] Furthermore, the moving guide rail consists of two parallel linear guide rails arranged on the upper plane of the base.

[0012] Furthermore, the base body is evenly provided with 2×3 pressing stations, and the pressing plate body is correspondingly provided with 2×3 contour pressing blocks.

[0013] Furthermore, it also includes a limit block. The base body moves along the moving guide rail to the limit block and stops at the pressing position. A limit switch is also provided at the pressing position. The limit switch and the limit block together fix the base body at the pressing position of the moving guide rail.

[0014] Compared with the prior art, the unique advantages of the technical solution provided in this application are as follows: This invention employs a linked design of the pressing component and the UV light irradiation component. Once the pressing is complete, the UV curing is triggered without interruption, eliminating process changeover time and significantly increasing production efficiency. Simultaneous operation also reduces internal stress in the adhesive layer, resulting in more uniform curing. Through a dual-cylinder drive and contoured pressing block design, combined with adjustable pressing stroke and speed, precise planar pressing is achieved, with adhesive layer thickness deviation controlled within ±0.02mm, reducing workpiece damage rate by 80%. The UV light source is integrated into a sealed enclosure, and with limit switches and an outer protective structure, ensures that the light irradiation only activates during pressing, automatically cutting off power upon opening the cover to prevent UV leakage. The transparent contoured base and array-style light source layout eliminate light shadows, improving curing efficiency by 40%. A guide rail-limit block-magnet positioning system enables automatic and precise base docking. Combined with a 2×3 array-style pressing station, it can process 6 workpieces at a time, adapting to the batch production needs of various product specifications. Attached Figure Description

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Example To address the problem in existing technologies where adhesive products (typically plastic housings) are first mechanically pressed and bonded before UV curing, the pressing and curing processes cannot be completed simultaneously. This increases process changeover time and can lead to stress defects in the adhesive layer due to excessively long pressing-curing intervals. This embodiment provides a pressing device based on a UV light source, suitable for assembly scenarios requiring UV curing, such as electronic components, medical devices, and optical devices.

[0020] Specifically, a pressing device based on a UV light source, such as Figure 1 As shown, it includes: a pressing assembly, which includes a displacement control mechanism, a pressing plate body 11, and at least one contouring pressing block 15 disposed on the pressing plate body 11; a movable contouring base, which includes a base body 21 and a movable guide rail 22. The base body 21 is provided with at least one pressing station 24 adapted to the contouring pressing block 15, and one or a group of dispensing products can be fixed on each pressing station 24; the pressing plate body 11 moves toward the base body 21 under the drive of the displacement control mechanism and completes the pressing operation of the dispensing products on the pressing station 24; the base body 21 can be moved along the movable guide rail 22 to the pressing position to complete the pressing operation. When the base body 21 is in the pressing station 24, it is within the irradiation range of the UV light irradiation component 30. When the base body 21 leaves the pressing position, it leaves the irradiation range of the UV light irradiation component 30.

[0021] Specifically, such as Figure 4 As shown, for example, a dispensing product includes an upper shell 62 and a lower shell 61. The lower shell 61 is provided with an adhesive tank 611, into which adhesive is injected.

[0022] Specifically, this device includes a pressing assembly, a movable contouring base, a UV light irradiation assembly 30, a housing, a base 40, and a control unit. The pressing assembly is fixed to the support frame 53 of the base 40 via a support block 13 and can be pressed down vertically; the movable contouring base is slidably connected to the base 40 via a guide rail and carries the workpiece to be processed; the UV light irradiation assembly 30 is integrated below the base body 21 and works in conjunction with the pressing assembly.

[0023] Specifically, the enclosure is constructed from a 304 stainless steel frame and UV-resistant acrylic panels, with double protective doors on the front and magnetic safety interlock switches installed on the sides of the doors. When the protective doors are opened, the interlock switches automatically cut off the power supply circuit to the UV irradiation component 30 to prevent UV leakage.

[0024] Specifically, such as Figure 3As shown, the displacement control mechanism consists of a support block 13, a control dual cylinder 12, an air valve switch 14, and a PLC controller. The control dual cylinder 12 is vertically fixed to the support frame 53 of the base 40, and its piston rod is rigidly connected to the pressure plate body 11. The air valve switch 14 is installed in the manual operation area on the right outer wall of the base 40 and is connected to the cylinder through an air pipe to control the start and stop of the pressing. Furthermore, a positioning post 16 is also provided on the pressure plate body 11 to ensure accurate pressing position.

[0025] Specifically, such as Figure 2 As shown, the base 40 is made of cast iron or marble, and the upper surface 41 is covered with two parallel linear guide rails with a spacing of 200mm. The bottom of the base body 21 is slidably connected to the guide rails via a slider, and the resistance to manual pushing is ≤5N.

[0026] The upper surface of the base body 21 has 2×3 pressing stations 24 arranged in an array, such as countersunk holes with a diameter of 20mm and a depth of 8mm, with a station spacing of 50mm×50mm; the bottom surface of the pressing plate body 11 is equipped with 2×3 silicone contour pressing blocks 15, with each pressing block corresponding to a station to ensure synchronous pressing of multiple workpieces. The base body 21 may also be equipped with a displacement handle 23 for convenient push-pull operation.

[0027] Specifically, the positioning and triggering mechanism includes: 1. Mechanical limit: A limit block 52 is provided at the end of the guide rail. When the base body 21 moves to the limit block 52, it is positioned by contact with the side buffer pad, with a repeatability accuracy of ±0.02mm. 2. Electrical interlock: A travel limit switch 51 is installed next to the limit block 52. After the base body 21 is in position, the switch is triggered, sending a signal to the PLC to start the pressing-curing process.

[0028] Workflow: Workpiece loading: Place the glued workpiece into the 2×3 pressing stations 24, manually push the base body 21 along the guide rail until it contacts the limit block 52 and is fixed by magnetic adsorption.

[0029] Pressing start: Pressing the air valve switch 14 will control the air supply of the double air cylinder 12, which will drive the main body of the pressure plate 11 to press down at a speed of 8mm / s. After the contour pressure block 15 contacts the workpiece, it will generate uniform pressure.

[0030] Curing trigger: The pressure plate body 11 is pressed down to the set stroke, triggering the limit switch 51. The PLC controls the UV light irradiation component 30 to start, and the irradiation time is adjustable from 30 to 120 seconds.

[0031] Reset and Retrieval: After curing is completed, the cylinder automatically depressurizes and resets, and the base 21 is manually pulled back to the initial position to remove the workpiece.

[0032] This invention employs a linkage design between the pressing component and the UV light irradiation component 30. Once pressing is complete, light curing is triggered without interruption, eliminating process changeover time and significantly increasing production efficiency. Simultaneous operation also reduces internal stress in the adhesive layer, resulting in more uniform curing. Through a dual-cylinder drive and contoured pressing block 15 design, combined with adjustable pressing stroke and speed, precise planar pressing is achieved, controlling adhesive layer thickness deviation within ±0.02mm and reducing workpiece damage rate by 80%. The UV light source is integrated into a sealed enclosure, and with the limit switch 51 and outer protective structure, ensures that light irradiation only activates during pressing, automatically cutting off power upon opening to prevent UV leakage. The transparent contoured base and array-style light source layout eliminate light shadows, improving curing efficiency by 40%. The guide rail-limit block 52-magnet positioning system enables automatic and precise base docking. Combined with a 2×3 array-style pressing station 24, it can process 6 workpieces at a time, adapting to the batch production needs of various product specifications.
