Description

Technical Field

[0001] This utility model relates to the field of glue potting and curing technology, specifically a glue potting and curing oven with a structure to prevent glue overflow. Background Technology

[0002] A potting curing oven is a device used to heat and cure potting compound on workpieces. It is widely used in packaging, bonding, and insulation processes in industries such as electronics, automobiles, aerospace, and communications. Its main function is to precisely control parameters such as temperature, humidity, and time to allow the potting compound to complete the curing reaction inside or on the surface of the workpiece, forming a colloidal layer with certain strength, insulation, and stability. This protects the electronic components and circuits inside the workpiece, improving the reliability and service life of the product.

[0003] In the prior art, Chinese Patent No. CN220177418U discloses a tube oven for dispensing and curing adhesive. The tube oven body is divided into a feeding section, a heating section, a cooling section, and a discharging section, and is further divided into several layers of interconnected air-cooled processing lines from top to bottom. The feeding section is equipped with a first fan and a first hot air inlet, which is connected to a heating device via a guide pipe and communicates with the inner chamber of the feeding section via the first fan. The heating section is equipped with a second fan and a second hot air inlet, which is connected to a heating device via a guide pipe and communicates with the inner chamber of the heating section via the second fan. The cooling section is equipped with a third fan and a cold air inlet, which is connected to a cooling device via a guide pipe and communicates with the inner chamber of the cooling section via the third fan. This design not only has heating and drying functions but also cooling functions, resulting in high space utilization and heat utilization. It can shorten the overall length, reduce costs, and improve production efficiency.

[0004] Based on the above materials, in the existing technology, during the actual use of the curing oven, the adhesive may overflow into the workpiece due to factors such as volume expansion, improper control of the amount of adhesive poured, or airflow interference within the curing oven. The overflow of adhesive not only contaminates the internal components of the equipment, affecting its normal operation and service life, but also leads to adhesive waste and increases production costs. In addition, it may also cause a decline in product quality, resulting in poor appearance and functional failure. Therefore, we propose a curing oven with an anti-overflow structure for adhesive. Utility Model Content

[0005] The purpose of this utility model is to provide a potting and curing oven with an anti-overflow structure to solve the problem mentioned in the background art. In the actual use of the curing oven, the adhesive may overflow into the potted workpiece due to factors such as volume expansion, improper control of the amount of adhesive poured, or airflow interference in the curing oven. The overflow of adhesive not only contaminates the internal components of the equipment, affecting the normal operation and service life of the equipment, but also leads to adhesive waste, increases production costs, and may also cause a decline in product quality, resulting in poor appearance and functional failure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a curing oven with an anti-overflow structure for adhesive, comprising a curing oven body, a conveyor belt inside the curing oven body, and an adhesive-filled workpiece placed on the outer wall of the conveyor belt. The curing oven body is provided with an anti-overflow mechanism to prevent adhesive from overflowing during the curing process of the adhesive-filled workpiece. The anti-overflow mechanism includes an adhesive-blocking frame disposed on the outer wall of the adhesive-filled workpiece, and an adhesive-blocking airbag fixedly installed on the inner wall of the adhesive-blocking frame. An air pump is fixedly installed on the top of the curing oven body, and an air pump is provided at the end of the air pump, with an air inlet pipe connected to the end of the air pump. An adjustment mechanism is provided on the outer wall of the adhesive-blocking frame for adjusting the height of the anti-overflow mechanism.

[0007] Furthermore, the cross-section of the glue-blocking frame is trapezoidal, and the top opening of the glue-blocking frame is smaller than the bottom opening, and the bottom inner diameter of the glue-blocking frame is larger than the outer diameter of the glue-filled workpiece.

[0008] Furthermore, the adhesive-blocking airbag is made of rubber, and the adhesive-blocking airbag covers the inner wall of the adhesive-blocking frame, and the outer wall of the adhesive-blocking airbag is in contact with the top outer wall of the glue-filled workpiece.

[0009] Furthermore, the air intake pipe is made of corrugated flexible hose, and one end of the air intake pipe is connected to the inside of the rubber-blocking airbag, while the other end of the air intake pipe is connected to the inflation pipe. The air intake pipe and the inflation pipe are symmetrically arranged on both sides of the rubber-blocking frame.

[0010] Furthermore, the adjustment mechanism includes a lifting slide rod fixedly installed on the outer wall of the glue-blocking frame, an adjustment column fixedly installed inside the curing oven body, and a compression spring inside the adjustment column. The end of the lifting slide rod is provided with a connecting rod, and the bottom of the connecting rod is provided with a lifting cylinder fixedly installed inside the curing oven body.

[0011] Furthermore, two sets of lifting slide rods are symmetrically arranged on the side wall of the rubber-blocking frame, and the ends of the lifting slide rods are slidably connected to the inner wall of the adjusting column. One end of the compression spring is in contact with the outer wall of the lifting slide rod, and the other end of the compression spring is in contact with the inner wall of the top of the adjusting column.

[0012] Furthermore, the adjusting column is symmetrically arranged on both sides of the transmission belt, and the outer wall of the adjusting column is provided with a lifting groove, the inner wall of the lifting groove being in contact with the outer wall of the lifting slide rod and the connecting rod.

[0013] Furthermore, the connecting rod is located between the two sets of lifting slide rods, and the bottom outer wall of the connecting rod is in contact with the output end of the lifting cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This potting and curing oven with an anti-overflow structure forms a double anti-overflow barrier through the combination design of a baffle frame and a baffle airbag. The trapezoidal cross-section baffle frame provides rigid support for the baffle airbag. The structure, which is narrow at the top and wide at the bottom, is suitable for potting workpieces of different sizes. After being inflated by an air pump, the rubber baffle airbag fits tightly against the top outer wall of the potting workpiece, filling the gap between the workpiece and the baffle frame. Even if the adhesive expands, it is difficult to overflow, significantly improving the anti-overflow effect. This can greatly reduce the contamination of internal components by the adhesive and extend the service life of the equipment.

[0016] 2. The lifting cylinder in the adjustment mechanism can precisely control the lifting height of the glue-blocking frame. Combined with the buffering effect of the compression spring, the glue-blocking frame can quickly adapt to glue-filling workpieces of different heights. When changing workpieces of different specifications, there is no need to manually disassemble or adjust the glue-blocking structure. Simply by controlling the extension and retraction of the lifting cylinder, the glue-blocking frame can be automatically raised and lowered to the appropriate position, which greatly improves the adaptability of the equipment to different workpieces, reduces the workload of operators, and effectively improves production efficiency.

[0017] 3. The corrugated hose air inlet pipe has good flexibility and high temperature resistance, and is not easy to bend or break during the lifting and lowering of the rubber baffle frame. This ensures that the air pump supplies stable air to the rubber baffle airbag. The symmetrically arranged air inlet and air inlet pipes make the rubber baffle airbag evenly stressed, avoiding sealing failure due to uneven local air pressure. Attached Figure Description

[0025] 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.

[0026] Example 1: Please refer to Figure 1-4 This utility model provides the following technical solution: a curing oven with an anti-overflow structure for adhesive, comprising a curing oven body 1, a conveyor belt 101 inside the curing oven body 1, and an adhesive-filled workpiece 2 placed on the outer wall of the conveyor belt 101. The curing oven body 1 is provided with an anti-overflow mechanism to prevent adhesive from overflowing during the curing process of the adhesive-filled workpiece 2. The anti-overflow mechanism includes an adhesive-blocking frame 3 disposed on the outer wall of the adhesive-filled workpiece 2, and an adhesive-blocking airbag 4 fixedly installed on the inner wall of the adhesive-blocking frame 3. An air pump 5 is fixedly installed on the top of the curing oven body 1, and an air inflator 501 is provided at the end of the air pump 5. An air inlet pipe 502 is connected to the end. The cross-section of the glue-blocking frame 3 is trapezoidal, and the top opening of the glue-blocking frame 3 is smaller than the bottom opening. The inner diameter of the bottom of the glue-blocking frame 3 is larger than the outer diameter of the glue-filled workpiece 2. The glue-blocking airbag 4 is made of rubber and covers the inner wall of the glue-blocking frame 3. The outer wall of the glue-blocking airbag 4 is in contact with the top outer wall of the glue-filled workpiece 2. The air inlet pipe 502 is made of corrugated hose. One end of the air inlet pipe 502 is connected to the inside of the glue-blocking airbag 4, and the other end of the air inlet pipe 502 is connected to the inflation pipe 501. The air inlet pipe 502 and the inflation pipe 501 are symmetrically arranged on both sides of the glue-blocking frame 3.

[0027] After the glue-filled workpiece 2 is placed on the conveyor belt 101 and sent into the curing oven body 1, the anti-overflow mechanism is activated. First, the air pump 5 starts working, delivering gas to the air inlet pipe 502 through the air inlet pipe 501. The corrugated hose air inlet pipe 502 has good flexibility and can adapt to the subsequent lifting and lowering movement of the glue-blocking frame 3 without affecting the gas transmission. The gas enters the glue-blocking airbag 4 covering the inner wall of the glue-blocking frame 3 through the air inlet pipe 502. As the gas is filled, the rubber glue-blocking airbag 4 gradually expands. Because the cross-section of the glue-blocking frame 3 is trapezoidal, the top opening is smaller than the bottom opening. Furthermore, the bottom inner diameter is larger than the outer diameter of the glue-filling workpiece 2. During the expansion process, the outer wall of the glue-blocking airbag 4 will tightly fit the top outer wall of the glue-filling workpiece 2, filling the gap between the workpiece and the glue-blocking frame 3 to form a sealed space. The glue-blocking frame 3 provides rigid support for the glue-blocking airbag 4. The two together form a double anti-overflow barrier. During the curing process of the glue in the glue-filling workpiece 2, even if the glue generates outward pressure due to factors such as volume expansion and airflow interference, it will be effectively blocked by the glue-blocking frame 3 and the glue-blocking airbag 4, thereby preventing the glue from overflowing, avoiding glue contamination of internal components of the equipment, reducing glue waste, and ensuring product quality.

[0028] Example 2: Please refer to Figure 3-6 Based on Embodiment 1, an adjustment mechanism is also disclosed, the specific structure of which is as follows: The outer wall of the glue-blocking frame 3 is provided with an adjustment mechanism for adjusting the height of the anti-overflow mechanism. The adjustment mechanism includes a lifting slide rod 7 fixedly installed on the outer wall of the glue-blocking frame 3. An adjustment column 6 is fixedly installed inside the curing oven body 1, and a compression spring 8 is provided inside the adjustment column 6. A connecting rod 701 is provided at the end of the lifting slide rod 7, and a lifting cylinder 9 fixedly installed inside the curing oven body 1 is provided at the bottom of the connecting rod 701. The lifting slide rod 7 is located on the side wall of the glue-blocking frame 3. Two sets are symmetrically arranged, and the end of the lifting slide rod 7 is slidably connected to the inner wall of the adjusting column 6. One end of the compression spring 8 is in contact with the outer wall of the lifting slide rod 7, and the other end of the compression spring 8 is in contact with the top inner wall of the adjusting column 6. The adjusting column 6 is symmetrically arranged on both sides of the transmission belt, and the outer wall of the adjusting column 6 is provided with a lifting groove 601. The inner wall of the lifting groove 601 is in contact with the outer wall of the lifting slide rod 7 and the connecting rod 701. The connecting rod 701 is located between the two sets of lifting slide rods 7, and the bottom outer wall of the connecting rod 701 is in contact with the output end of the lifting cylinder 9.

[0029] The adjustment mechanism is used to adapt to workpieces 2 of different heights. When it is necessary to cure the glue on workpieces 2 of different specifications, the control system sends a command to the lifting cylinder 9. The output end of the lifting cylinder 9 extends upward, pushing the connecting rod 701 located between the two sets of lifting slide rods 7 to move upward. The lifting slide rods 7 are symmetrically fixedly installed on the outer wall of the glue-blocking frame 3, and their ends are slidably connected to the inner wall of the adjusting column 6. The outer wall of the adjusting column 6 is provided with a lifting groove 601. The lifting slide rods 7 and the connecting rod 701 can slide in the lifting groove 601. Under the push of the connecting rod 701, the lifting slide rods 7 drive the glue-blocking frame 3 to move upward. When the slide bar 3 moves upward, the compression spring 8 is compressed, providing a buffer and restoring force for the lifting slide bar 7. When the glue-blocking frame 3 rises to the appropriate height, the lifting cylinder 9 stops moving, and the glue-blocking frame 3 remains stably in that position, allowing the glue-blocking airbag 4 to fit tightly against the top of the glue-filling workpiece 2. When the specifications of the glue-filling workpiece 2 need to be changed and the height of the glue-blocking frame 3 needs to be lowered, the output end of the lifting cylinder 9 retracts. Under the elastic force of the compression spring 8, the lifting slide bar 7 and the glue-blocking frame 3 move downward until they reach the appropriate position, thereby achieving precise and flexible adjustment of the height of the glue-blocking frame 3 to adapt to glue-filling workpieces 2 of different heights.
