Description

Technical Field

[0001] The utility model relates to an adhesive device for a gas interceptor applied to the blood separation process, belonging to the field of gas interceptors. Background Art

[0002] The gas interceptor is one of the components of the blood component separator, and its function is to intercept the residual gas that may be mixed in the blood component separation process to prevent the gas from entering the human body and causing harm. The entry of air into the human blood vessels may cause air embolism, embolizing various small arterial blood vessels. The more air there is, the larger the embolized blood vessels will be. There may be pulmonary embolism, coronary artery embolism and cerebral artery embolism, inducing serious critical conditions and endangering life at any time. Therefore, the production qualification rate of the gas interceptor plays a key role in the whole product working process.

[0003] The structure of the gas interceptor consists of an upper shell and a lower shell, and the upper and lower shells are bonded with dichloromethane adhesive. The current bonding operation is to dip the outer ring of the upper shell with the adhesive first, then dip the inner ring of the lower shell with the adhesive, and then align the upper and lower shells for bonding. The existing operation has the following difficulties: First, it is difficult to control the amount of adhesive. If the amount of adhesive is too small, the bonding firmness may not meet the design requirements, and even liquid leakage may occur; if the amount of adhesive is too much, it may lead to the phenomenon of glue overflow, affecting the appearance of the product. Second, the glue application depth of the adhesive cannot be accurately controlled. If the glue application depth is too shallow, the bonding will be insecure and leakage will occur; if the glue application depth is too deep, the glue will overflow, affecting the use of the product. Finally, the manual bonding process takes 1.5 minutes per piece. This product is a disposable consumable with a large production demand. Therefore, the time-consuming manual bonding is too long to meet the production requirements of this product and consumes a large amount of labor costs. Summary of the Invention

[0004] According to the problems described in the background, the problem to be solved by the utility model is to provide an adhesive device for a gas interceptor applied to the blood separation process. Through a specially designed adhesive cartridge and by using a cylinder to control the docking of the upper and lower shells of the gas interceptor after dipping, the problems of glue overflow caused by too much and too deep adhesive and insecure bonding and leakage caused by too little and too shallow adhesive are solved, and the problem of consuming a large amount of labor costs is also solved.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A bonding device for a gas interceptor in the blood separation process is provided, including a device bracket, a fixed crossbar, a gas path interface, an upper cover linear cylinder, an upper cover rotary cylinder, an upper cover linear cylinder push rod, an upper cover gripper, a lower cover linear cylinder, a lower cover rotary cylinder, a lower cover linear cylinder push rod, a lower cover gripper, an upper cover adhesive cartridge, a lower cover adhesive cartridge, an upper cover of the gas interceptor, and a lower cover of the gas interceptor. The upper part of the front of the device bracket is provided with a fixed crossbar, and the left and right ends of the fixed crossbar are connected to both ends of the device bracket. The gas path interface is installed on the side of the device bracket and is flush with the fixed crossbar. The upper cover rotary cylinder is installed on the front of the fixed crossbar and is located on the left part of the fixed crossbar. The upper cover linear cylinder is installed at the same position as the upper cover rotary cylinder and the initial position is vertically downward. The lower end of the upper cover linear cylinder is installed with an upper cover linear cylinder push rod, and the other end of the upper cover linear cylinder push rod is installed with an upper cover gripper. The lower cover rotary cylinder is installed on the front of the fixed crossbar and is located on the right part of the fixed crossbar. The lower cover linear cylinder is installed at the same position as the lower cover rotary cylinder and the initial position is vertically downward. The lower end of the lower cover linear cylinder is installed with a lower cover linear cylinder push rod, and the other end of the lower cover linear cylinder is installed with a lower cover gripper. The upper cover adhesive cartridge is located on the front of the device bracket and directly below the upper cover gripper. The lower cover adhesive cartridge is located on the front of the device bracket and directly below the lower cover gripper.

[0006] Preferably, the upper cover adhesive cartridge includes an upper cover adhesive cartridge wall, an inner support of the cartridge, and an upper cover bonding ring. There are multiple inner supports of the cartridge inside the upper cover adhesive cartridge wall. An upper cover bonding ring is installed on the inner support of the cartridge. Absorbent cotton is also wound around the upper cover bonding ring. The inner diameter of the upper cover bonding ring is the same as the outer diameter of the upper cover of the gas interceptor.

[0007] Preferably, the lower cover adhesive cartridge includes a lower cover adhesive cartridge wall and a lower cover bonding ring. The lower cover bonding ring is located inside the lower cover adhesive cartridge wall and absorbent cotton is also wound around it. The outer diameter of the lower cover bonding ring is the same as the inner diameter of the lower cover of the gas interceptor.

[0008] Preferably, the upper cover of the gas interceptor makes contact with the absorbent cotton on the upper cover bonding ring saturated with the adhesive through the outer wall of the upper cover of the gas interceptor, so that it is covered with the adhesive. The absorbent cotton can make the adhesive better adhere and can also control the amount of the adhesive, ensuring that the amount is just right.

[0009] Preferably, the lower cover of the gas interceptor makes contact with the absorbent cotton on the lower cover bonding ring saturated with the adhesive through the inner wall of the lower cover of the gas interceptor, so that it is covered with the adhesive. The absorbent cotton can make the adhesive better adhere and can also control the amount of the adhesive, ensuring that the amount is just right.

[0010] Preferably, the grasping pattern of the upper cover grasping is the upper end pattern of the upper cover of the gas interceptor, and the grasping pattern of the lower cover grasping is the lower end pattern of the lower cover of the gas interceptor. At the same time, the upper cover grasping and the lower cover grasping are rubber reverse molds, and the reverse mold pattern is smaller than the upper end pattern of the upper cover of the gas interceptor and the lower end pattern of the lower cover of the gas interceptor, so an interference fit will be formed, and both the upper cover and the lower cover will be firmly clamped, and will not fall off when dipping the adhesive and docking.

[0011] Preferably, the components grasped by the upper cover grasping and the lower cover grasping are the upper cover of the gas interceptor and the lower cover of the gas interceptor.

[0012] Preferably, the mating installation of the upper cover of the gas interceptor and the lower cover of the gas interceptor is that the outer wall of the upper cover of the gas interceptor and the inner wall of the lower cover of the gas interceptor are bonded by an adhesive.

[0013] Preferably, both the upper cover rotating cylinder and the lower cover rotating cylinder rotate 90°, and after the upper cover rotating cylinder and the lower cover rotating cylinder rotate, the upper cover grasping and the lower cover grasping are opposite to each other, and at the same time, the upper cover of the gas interceptor and the lower cover of the gas interceptor grasped by the upper cover grasping and the lower cover grasping can be correspondingly mated.

[0014] Preferably, the gas path interface controls the upper cover linear cylinder, the upper cover rotating cylinder, the lower cover linear cylinder and the lower cover rotating cylinder respectively, so that these cylinders can move independently, avoiding the situation where small-scale repairs cannot be carried out when the cylinders are damaged or other situations occur.

[0015] Working principle: The upper cover of the gas interceptor and the lower cover of the gas interceptor are respectively installed on the upper cover grasping and the lower cover grasping. Due to the interference relationship, the upper cover of the gas interceptor and the lower cover of the gas interceptor will not fall off. Then the upper cover linear cylinder and the lower cover linear cylinder operate, and the push rods of the upper cover linear cylinder and the lower cover linear cylinder push forward, so that the upper cover of the gas interceptor and the lower cover of the gas interceptor on the upper cover grasping and the lower cover grasping respectively enter the upper cover adhesive cartridge and the lower cover adhesive cartridge to dip the adhesive. Due to the effect of the absorbent cotton on the upper cover bonding ring and the lower cover bonding ring, the adhesive is evenly attached to the outer wall of the upper cover of the gas interceptor and the inner wall of the lower cover of the gas interceptor. Then the upper cover linear cylinder and the lower cover linear cylinder resume operation, the upper cover rotating cylinder and the lower cover rotating cylinder operate, so that the upper cover of the gas interceptor and the lower cover of the gas interceptor rotate to align, and then the lower cover linear cylinder operates to move the lower cover of the gas interceptor to the left until the docking with the upper cover of the gas interceptor is completed, completing the docking of one gas interceptor, and starting to cycle.

[0016] The beneficial effects of the present utility model are:

[0017] 1. Through the special adhesive cartridge, the amount and depth of the adhesive dipped by the upper and lower shells can be controlled, ensuring firm bonding without leakage, and the phenomenon of glue overflow can also be avoided, improving the qualified rate of products.

[0018] 2. The rubber gripper ensures that the upper and lower shells will not fall off, enhancing the efficiency and stability of component production.

[0019] 3. By using a linear cylinder to dip the adhesive and a rotary cylinder for docking, the production efficiency can be significantly improved. Moreover, through a series of mechanical actions, the stability of dipping and docking is ensured.

[0020] 4. Dipping and docking are not performed manually, reducing personnel consumption. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed cross bar 2 is installed on the upper front of the device bracket 1 and the fixed cross bar 2 connects the two ends of the device bracket 1 on the left and right. The gas circuit interface 3 is installed on the side of the device bracket 1 and is flush with the fixed cross bar 2. The upper cover rotating cylinder 5 is installed on the front of the fixed cross bar 2 and is located at the left part of the fixed cross bar 2. The upper cover linear cylinder 4 is installed on the upper cover rotating cylinder 5. The same position and the initial position is vertically downward, the upper cover linear cylinder 4 is equipped with an upper cover linear cylinder push rod 6 at the lower end, and the upper cover grab 7 is installed at the other end of the upper cover linear cylinder push rod 6, the lower cover rotating cylinder 9 is installed on the front of the fixed cross bar 2 and is located at the right part of the fixed cross bar 2, the lower cover linear cylinder 8 is installed at the same position as the lower cover rotating cylinder 9 and the initial position is vertically downward, the lower cover linear cylinder 8 is equipped with a lower cover linear cylinder push rod 10 at the lower end, and the lower cover grab 11 is installed at the other end of the lower cover linear cylinder 8, the upper cover adhesive barrel 12 is located on the front of the device bracket 1 and directly below the upper cover grab 7, the lower cover adhesive barrel 13 is located on the front of the device bracket 1 and directly below the lower cover grab 11, and the device can be moved at will, and a suitable place can be selected for operation.

[0031] The upper cover adhesive barrel 12 comprises an upper cover adhesive barrel wall 121, inner barrel supports 122 and an upper cover adhesive ring 123. The upper cover adhesive barrel wall 121 is provided with a plurality of inner barrel supports 122. The upper cover adhesive ring 123 is mounted on the inner barrel supports 122. The upper cover adhesive ring 123 is also wrapped with absorbent cotton. The inner diameter of the upper cover adhesive ring 123 is the same as the outer wall diameter of the gas interceptor upper cover 14. When matching with the outer wall of the gas interceptor upper cover 14, the outer wall of the gas interceptor upper cover 14 is dipped with corresponding adhesive.

[0032] The lower cover adhesive barrel 13 comprises a lower cover adhesive barrel wall 131 and a lower cover adhesive ring 132. The lower cover adhesive ring 132 is located inside the lower cover adhesive barrel wall 131 and is also wrapped with absorbent cotton.

At the same time, the upper cover gripper 7 and the lower cover gripper 11 are rubber reverse molds, and the reverse mold pattern is smaller than the upper end pattern of the upper cover 14 of the gas interceptor and the lower end pattern of the lower cover 15 of the gas interceptor. In this way, an interference fit will be formed, and both the upper cover and the lower cover will be firmly clamped, preventing them from falling off during dipping the adhesive and docking.

[0036] The components grasped by the upper cover gripper 7 and the lower cover gripper 11 are the upper cover 14 of the gas interceptor and the lower cover 15 of the gas interceptor.

[0037] The mating installation of the upper cover 14 of the gas interceptor and the lower cover 15 of the gas interceptor is that the outer wall of the upper cover 14 of the gas interceptor and the inner wall of the lower cover 15 of the gas interceptor are bonded together with an adhesive.

[0038] Both the upper cover rotating cylinder 5 and the lower cover rotating cylinder 9 rotate by 90°. After the upper cover rotating cylinder 5 and the lower cover rotating cylinder 9 rotate, the upper cover gripper 7 and the lower cover gripper 11 face each other, and at the same time, the upper cover 14 of the gas interceptor and the lower cover 15 of the gas interceptor grasped by the upper cover gripper 7 and the lower cover gripper 11 can be correspondingly mated.

[0039] The gas path interface 3 controls the upper cover linear cylinder 4, the upper cover rotating cylinder 5, the lower cover linear cylinder 8, and the lower cover rotating cylinder 9 respectively, enabling these cylinders to move independently, avoiding the inability to perform minor repairs when a cylinder is damaged or other situations occur.

[0040] Install the upper cover 14 of the gas interceptor and the lower cover 15 of the gas interceptor onto the upper cover gripper 7 and the lower cover gripper 11 respectively. Due to the interference fit, the upper cover 14 and the lower cover 15 of the gas interceptor will not fall off. Then, the upper cover linear cylinder 4 and the lower cover linear cylinder 8 operate, and the upper cover linear cylinder push rod 6 and the lower cover linear cylinder push rod 10 push forward, causing the upper cover 14 and the lower cover 15 of the gas interceptor on the upper cover gripper 7 and the lower cover gripper 11 to enter the upper cover adhesive cartridge 12 and the lower cover adhesive cartridge 13 respectively to dip the adhesive. Due to the function of the absorbent cotton on the upper cover bonding ring 123 and the lower cover bonding ring 132, the adhesive evenly adheres to the outer wall of the upper cover 14 of the gas interceptor and the inner wall of the lower cover 15 of the gas interceptor. Then, the upper cover linear cylinder 4 and the lower cover linear cylinder 8 resume operation, and the upper cover rotary cylinder 5 and the lower cover rotary cylinder 9 operate to rotate the upper cover 14 and the lower cover 15 of the gas interceptor until they are aligned. Then, the lower cover linear cylinder 8 operates to move the lower cover 15 of the gas interceptor to the left until the docking with the upper cover 14 of the gas interceptor is completed, completing the docking of one gas interceptor, and starting to cycle.
