Description

Technical Field

[0001] This utility model relates to the technical field of UV-curable adhesive production equipment, specifically a potting device for UV-curable adhesive production. Background Technology

[0002] In the production process of UV-curable adhesives, potting is a key step to ensure product quality. As a special type of adhesive, the core characteristic of UV-curable adhesives is that they will rapidly cure under the irradiation of specific light such as ultraviolet light. If they cure prematurely, not only will the adhesive lose its usability, but it may also clog the pipes, filling heads and other components of the potting device, causing equipment failure and increasing production downtime and maintenance costs.

[0003] Currently, although UV-curable adhesive filling devices on the market have taken light-shielding requirements into account, they usually use light-shielding materials to make the storage tank or set up simple light shields in the filling area. However, there are still obvious defects in actual filling operations. When filling bottles, the bottles often need to enter the filling station from the conveyor track. During this process, the bottles are inevitably exposed to the ambient light of the workshop. Especially in production workshops with strong light, the ambient light may cause the adhesive in the bottle to cure prematurely in some areas, affecting product performance. After filling, a small amount of adhesive will remain at the discharge end of the filler. Existing devices cannot ensure that the filler is always in a dark environment. The residual adhesive is easy to solidify and clump under the action of light, which not only affects the accuracy of the next filling, but also requires frequent cleaning of the filling head, reducing production efficiency.

[0004] In addition, the light-shielding structure design of some filling and sealing devices is unreasonable. Either the light-shielding range is limited and cannot fully cover the key areas of the bottle and the filling device, or the operation is complicated and the light-shielding parts need to be manually adjusted when the bottle enters or leaves the filling station. This makes it difficult to meet the high-efficiency operation requirements of automated production lines. Therefore, we need to provide filling and sealing devices for the production of UV-curable adhesives. Utility Model Content

[0005] The purpose of this invention is to provide a filling device for the production of light-curing adhesives. The filling device is placed inside a sunshade box, and a sunshade mechanism is set up to send the bottle to be filled into the sunshade box for filling. The filling operation is carried out in a dark environment. At the same time, when the bottle leaves the sunshade box, it can automatically block the light from the bottom opening of the sunshade box, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a potting and encapsulation device for producing photocurable adhesives, comprising:

[0007] The sunshade box includes a filling device, a bottle body, and a sunshade mechanism. The filling device is installed inside the sunshade box. The top tube of the filling device is connected to an external glue tank. The sunshade mechanism is installed inside the sunshade box to allow the bottle body to be filled in a low-light environment.

[0008] The sunshade mechanism includes a push plate, a limiting platform, a cylinder, and a guide tube. The push plate is slidably installed at the bottom of the sunshade box and has a limiting platform on its surface. The limiting platform is used to position and place the bottle. A cylinder for adjusting the height of the push plate is embedded in the bottom of the sunshade box. The guide tube is located at the top of the bottle and is embedded in the bottom of the sunshade box.

[0009] Preferably, the limiting platform includes an arc-shaped plate and an arc-shaped foam. The two arc-shaped plates are located on both sides of the bottle body and fixed to the surface of the push plate. An arc-shaped foam is fixedly installed on each adjacent side of the two arc-shaped plates.

[0010] Preferably, the guide cylinder is provided with a shielding component, which includes a frame, a conical seat, a spring, a bracket, and a top plate. The guide cylinder has a frame embedded in both sides, and a conical seat is slidably installed in the frame. The top plate is fixedly installed on the surface of the conical seat by the bracket, and a spring is provided between the bracket and the guide cylinder.

[0011] Preferably, two top plates are located at the top of the guide cylinder for sunshading the top of the guide cylinder. A rod is slidably installed inside the bracket, with one end of the rod fixed to the surface of the guide cylinder and the surface being movably connected to a spring.

[0012] Preferably, two sealing rings are fixedly installed inside the guide cylinder.

[0013] Preferably, the surface of the bottle is configured as a conical surface for use in conjunction with the conical seat.

[0014] Preferably, the sunshade box is provided with a collection device for catching liquid leakage from the drain end of the filling device.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention places the filling device inside a sunshade box, combined with a sunshade mechanism, allowing the entire filling process to be conducted in a dark environment, eliminating light interference, preventing premature curing of the adhesive, and ensuring product quality. The bottle is fed into the sunshade box for filling, reducing the time it is exposed to external light and lowering the risk of the adhesive being affected. When the bottle is removed, the bottom opening of the sunshade box automatically blocks light, keeping the box continuously dark and ensuring that the filling device and any residual adhesive inside do not cure due to light. This reduces equipment blockage and cleaning frequency, improving production efficiency. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a potting and encapsulation device for producing photocurable adhesives, comprising:

[0026] The sunshade box 1, filling device 2, bottle body 3 and sunshade mechanism 4 are provided. The filling device 2 is installed inside the sunshade box 1. The top tube of the filling device 2 is connected to the external glue tank. The sunshade mechanism 4 is installed inside the sunshade box 1 to make the bottle body 3 fill in a low light environment.

[0027] The sunshade mechanism 4 includes a push plate 41, a limiting platform 42, a cylinder 43, and a guide tube 44. The push plate 41 is slidably installed at the bottom of the sunshade box 1, and the limiting platform 42 is provided on its surface. The limiting platform 42 is used to position and place the bottle 3. The bottom of the sunshade box 1 is embedded with a cylinder 43 for adjusting the height of the push plate 41. The guide tube 44 is located at the top of the bottle 3 and is embedded in the bottom of the sunshade box 1.

[0028] Specifically, the filling device 2 is placed inside the sunshade box 1, and a sunshade mechanism 4 is set up. The bottle 3 that needs to be filled with adhesive is sent into the sunshade box 1 for filling, so that the filling operation is carried out in a dark environment. At the same time, when the bottle 3 leaves the sunshade box 1, it can automatically block the light from the bottom opening of the sunshade box 1. By placing the filling device 2 inside the sunshade box 1 and combining it with the sunshade mechanism 4, the filling process can be carried out in a dark environment, eliminating light interference, preventing the adhesive from curing prematurely, and ensuring product quality. When the bottle 3 is sent into the sunshade box 1 for filling, the time exposed to external light is reduced, reducing the risk of the adhesive being affected. When the bottle 3 leaves, the bottom opening of the sunshade box 1 can automatically block the light, keeping the sunshade box 1 dark and ensuring that the filling device 2 and the residual adhesive inside will not cure due to light, reducing equipment blockage and cleaning frequency, and improving production efficiency.

[0029] The limiting platform 42 includes an arc-shaped plate 421 and an arc-shaped foam 422. The two arc-shaped plates 421 are located on both sides of the bottle body 3 and are fixed on the surface of the push plate 41. An arc-shaped foam 422 is fixedly installed on the adjacent side of the two arc-shaped plates 421.

[0030] Furthermore, the curved plate 421 is made of 0.5-1mm thick spring 53 steel, and the curved foam 422 is closed-cell EPDM foam with a density of 30-50kg / m³. The curved foam 422 is bonded to the curved plate 421 with food-grade silicone adhesive, and the side of the curved foam 422 away from the curved plate 421 has a wavy protrusion. The distance between the two curved plates 421 is 2-5mm less than the diameter of the bottle 3. When the bottle 3 is placed on the limiting platform 42, the curved foam 422 is compressed and deformed by 5-8mm, forming a circumferential contact with the surface of the bottle 3. The spring 53 steel curved plate 421 provides elastic clamping force. Combined with the cushioning characteristics of EPDM foam, it can not only adapt to different bottles 3 with a diameter error of ±3mm, but also avoid damage to the bottle 3 caused by hard contact. The wavy protrusion increases the friction with the bottle 3 and prevents the bottle 3 from shaking when the push plate 41 is raised and lowered, solving the problem of poor compatibility with bottle 3 specifications and easy slippage of traditional limiting structures.

[0031] The guide cylinder 44 is provided with a shielding component 5, which includes a frame 51, a conical seat 52, a spring 53, a bracket 54 and a top plate 55. The guide cylinder 44 is embedded in both sides of the frame 51. The conical seat 52 is slidably installed in the frame 51. The top plate 55 is fixedly installed on the surface of the conical seat 52 through the bracket 54. A spring 53 is provided between the bracket 54 and the guide cylinder 44.

[0032] It is worth noting that the frame 51 is a rectangular steel channel with a polytetrafluoroethylene coating on the inner wall, the conical seat 52 has a conical angle of 30°-45°, and the surface is coated with a 0.1mm thick titanium nitride wear-resistant layer; the bracket 54 is an L-shaped aluminum alloy profile, one end of which is fixed to the conical seat 52 by a countersunk bolt, and the other end is welded to the top plate 55; the spring 53 is a stainless steel compression spring with a diameter of 1.5-2mm, and its length in its natural state is 8-10mm longer than the distance between the bracket 54 and the guide cylinder 44. The polytetrafluoroethylene coating reduces the sliding resistance of the conical seat 52, and the titanium nitride layer reduces the wear rate by more than 60%; the stainless steel compression spring provides stable rebound force, ensuring that the top plate 55 can close quickly after the bottle 3 is lowered, solving the problem of delayed light blocking caused by excessive friction or insufficient elasticity of traditional blocking parts 5.

[0033] Two top plates 55 are located on the top of the guide cylinder 44 to provide shade for the top of the guide cylinder 44. A rod 6 is slidably installed inside the bracket 54. One end of the rod 6 is fixed to the surface of the guide cylinder 44, and the surface is movably connected to the spring 53.

[0034] It is worth noting that the rod 6 is a chrome-plated carbon steel rod, and a limiting nut is provided at the end away from the guide cylinder 44; the sliding hole on the bracket 54 is clearance-fitted with the rod 6, and the two ends of the spring 53 abut against the annular bosses on the surfaces of the bracket 54 and the guide cylinder 44, respectively. The compression of the spring 53 changes linearly with the opening and closing angle of the top plate 55. The chrome-plated rod 6 and the precision sliding hole fit together to ensure that the bracket 54 moves in a straight line, avoiding the light-blocking gap caused by the offset of the top plate 55; the limiting nut prevents the bracket 54 from detaching from the rod 6, and together with the linearly changing force of the spring 53, the opening and closing process of the top plate 55 is smooth and without jamming, solving the problem of light-blocking failure caused by the offset of the movement trajectory of the blocking part 5.

[0035] Two sealing rings 7 are fixedly installed inside the guide cylinder 44;

[0036] Specifically, the sealing ring 7 is made of fluororubber with a Shore hardness of 60-70 and has a "U" shaped cross-section. It is nested in the annular groove on the inner wall of the guide cylinder 44 through an interference fit. When the bottle body 3 passes through, the lip of the sealing ring 7 flips outward and forms a line contact seal with the surface of the bottle body 3. The fluororubber sealing ring 7 is resistant to the corrosion of the adhesive and undergoes adaptive deformation when the bottle body 3 is inserted. The double sealing structure reduces the light transmittance. The line contact design ensures the light-blocking effect and controls the frictional resistance to within 5N, solving the contradiction of traditional sealing structures either leaking light or jamming the bottle body 3.

[0037] The surface of the bottle body 3 is set as a conical surface for use in conjunction with the conical seat 52;

[0038] The taper of the conical surface of the bottle body 3 is consistent with the angle of the conical surface of the conical seat 52. The height of the conical surface is 30-50mm, and a frosted section is provided within 10mm of the top of the bottle body 3. When the bottle body 3 rises to the filling position, the frosted section and the sealing ring 7 form a secondary seal. The matching taper design allows the bottle body 3 to accurately push open the conical seat 52 when it rises, ensuring that the top plate 55 opens synchronously. The frosted section increases the friction with the sealing ring 7, preventing the bottle body 3 from rotating accidentally during filling and solving the problem of liquid displacement caused by inaccurate positioning of the bottle body 3.

[0039] The sunshade box 1 is equipped with a collection device for catching the leakage from the drain end of the filling machine 2;

[0040] The collection component includes a motor for driving the filling machine 2 to rotate. The collection plate is fixed to the inner wall of the sunshade box 1 by magnetic attraction, and its area is three times the projected area of ​​the drain end of the filling machine 2. The stainless steel collection plate is resistant to the corrosion of the cured adhesive, which solves the problems of leakage contaminating the equipment and difficulty in cleaning after curing.

[0041] The filling device 2 and cylinder 43 involved in this application are both implemented using existing mature technologies and connected to an external PLC controller and power supply. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.

[0042] This device places the bottle 3 between two arc-shaped plates 421. The bottle 3 is then squeezed by the arc-shaped foam 422 within the plates 421, providing auxiliary clamping. The cylinder 43 is activated, causing the push plate 41 and bottle 3 to move upwards. The guide cylinder 44, positioned directly above the bottle 3, allows the bottle 3 to be inserted into it. Because the guide cylinder 44 has two sealing rings 7 on its inner wall, these rings deform upon contact with the bottle 3, providing light shielding. As the bottle 3 rises, its conical surface presses against two conical seats 52, causing them to move away from each other. The conical seats 52 then move the support 54 and top plate 55, further distancing the two top plates. At this point, the filling device 2 is activated, injecting the UV-curable adhesive into the bottle 3. After completion, the cylinder 43 drives the push plate 41 downwards. After the bottle body 3 is filled with glue, it becomes heavier and will not get stuck in the guide cylinder 44. The sealing ring 7 on the inner wall of the guide cylinder 44 serves to block light and has a small clamping force on the bottle body 3. After the bottle body 3 is filled, it is pushed out and the bottle cap is quickly tightened manually to seal it. Under the action of the spring 53, the two top plates 55 are brought closer together to block the light on the top of the guide cylinder 44 again. Adhesive layer can be provided on the adjacent side of the two top plates 55. A collection part is provided to prevent the bottom of the filling device 2 from dripping onto the top plate 55. After filling is completed, the motor is started to drive the filling device 2 to rotate, and the bottom drain port of the filling device 2 is rotated to the top of the collection plate. The collection plate is snapped into the inner wall of the sunshade box 1. The sunshade box 1 has a sealed cabinet door that can be opened. The top of the filling device 2 is connected to the external liquid supply equipment through a corrugated pipe.
