Description

Technical Field

[0001] This invention relates to the field of sealing ring production, specifically a sealing ring suction device. Background Technology

[0002] After the sealing ring is injection molded, it is removed from the mold. In existing technologies, mechanical gripping is often used. However, traditional mechanical gripping only grips one point of the ring. The ring is still at a relatively high temperature after molding. Improper removal methods may lead to uneven stress on the ring during demolding, causing defects such as ring deformation during ejection. Furthermore, since the sealing ring is inside the mold core, mechanical gripping can easily cause deformation of the ring opening, affecting the molding quality. At the same time, during the production of the sealing ring, there is a sprue connected to the sealing ring at the injection gate. The actual product used is the ring included in the sealing ring. The sprue needs to be recycled. In existing technologies, a robot is used to grip and collect the sealing ring as a whole. Subsequently, the ring and sprue on the sealing ring need to be separated and re-sorted, which increases the workload of processing the sealing ring as a whole. Summary of the Invention

[0003] The purpose of this invention is to provide a sealing ring suction device, which replaces the mechanical gripping method of the sealing ring in the prior art with a method of suctioning the sealing ring by an air suction component. At the same time, the two air paths of the air suction component can be used to suction and separate the ring on the sealing ring and the pouring head on the sealing ring respectively, so as to solve the problems mentioned in the background art.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1:

[0024] like Figure 1 As shown in the embodiment of the present invention, a sealing ring suction device is provided, wherein the sealing ring includes a circular ring and an injection-molded gating head, and the sealing ring suction device includes a suction assembly with an air tube and a panel connected to the air tube.

[0025] The suction assembly 10 can be, but is not limited to, a vacuum pump. A pipe connected to the suction assembly 10 can connect to a gas path of the suction assembly 10. This gas path can be controlled by the suction assembly to suction or blow air into the pipe. When the pipe suctions air, it forms a vacuum zone on the panel, adsorbing the sealing ring onto the panel. When the pipe blows air, it can blow the sealing ring away from the panel, completing the removal operation of the sealing ring.

[0026] like Figure 1As shown, the panel has a suction groove configured to accommodate the sealing ring. The suction groove includes an annular groove 31 for placing the ring and a recessed groove 35 for placing the pouring head. The annular groove 31 has a venting hole 21 penetrating the panel and several suction holes 22. The venting hole 21 is located within the recessed groove and corresponds to the center of the pouring head. The suction holes 22 are located within the annular groove 31. The axial angles of the suction holes 22 and venting holes 21 penetrating the panel include, but are not limited to, 90 degrees, 45 degrees, and 15 degrees. The air pipe connects to a suction cup 24 and the suction holes 22, guiding the air... All holes 21 are sealed connections. The annular groove and recess can perfectly match the ring and the gating on the sealing ring. After the sealing ring is produced, it is pushed out by the mold core into the suction groove of the panel. The annular groove and recess limit the ring and the gating respectively. At the same time, the air pipe on the suction assembly connection 10 sucks air through the suction cup, so that the air guide hole and the suction hole adsorb the ring and the gating respectively. After the sealing ring is adsorbed, compared with the existing technology of grasping by a robot, the present invention can increase the force-bearing area of ​​the sealing ring and avoid the deformation of the sealing ring caused by the stress concentration of the robot on the sealing ring.

[0027] The suction cup 24 is sealed to both the suction hole 22 and the air guide hole 21. The suction hole 22 corresponds to the position of the ring, and the air guide hole 21 corresponds to the position of the pouring head. Therefore, under the action of the suction assembly, the sealing ring can be controlled by the suction cup 24.

[0028] The aforementioned panel may include a detachable and fixed connecting plate 20 and a limiting plate 30. An air suction groove is provided on the limiting plate 30 to limit the sealing ring pushed out by the mold core. At the same time, the air guide hole and the air suction hole are respectively provided on the connecting plate and the limiting plate 30. In this case, not only will the limiting effect on the sealing ring be not affected, but the limiting plate can also be replaced according to the size of the sealing ring, increasing the applicability of the overall device.

[0029] like Figure 1-2 As shown, the panel may include a detachable and fixed connecting plate 20 and a limiting plate 30. An air intake groove is formed on the limiting plate 30. The air intake groove is a through groove. A crescent-shaped block 34 fixed to the connecting plate is provided in the annulus formed by the air intake groove. The cavity formed between the outer surface of the crescent-shaped block and the side surface of the air intake groove can limit the sealing ring. At the same time, in this case, the limiting block 30 and the crescent-shaped block 34 can be selected and replaced according to the size of the sealing ring, increasing the applicability of the overall device.

[0030] On the side of the panel near the suction groove 31, a strip groove 33 is formed that communicates with the sealing ring groove 31. A section of the arc of the suction groove 31 coincides with the strip groove 33. The depth of the strip groove and the sealing ring groove are equal. Sensors are fixed on both sides of the panel. The sensors on both sides play the roles of infrared emission and reception, respectively. The function of the strip groove is to form a path between the infrared emission and reception ends of the sensors on both sides. At the same time, a section of the arc of the suction groove coincides with the strip groove 33. Therefore, when the sealing ring is pushed into the suction groove by the mold core, the sealing ring disrupts the infrared emission and reception path of the sensor. Through the above principle, the sensor can identify the sealing ring.

[0031] Example 2:

[0032] like Figure 1 As shown in the embodiment of the present invention, a sealing ring suction device is provided, wherein the sealing ring includes a circular ring and an injection-molded gating head. The sealing ring suction device includes a suction assembly with two air pipes and a panel. A suction cup 24 and a suction nozzle 23 are respectively fixed on the two air pipes. The suction cup 24 and the suction nozzle 23 are respectively sealed and connected to the suction hole 22 and the air guide hole 21 opened on the panel.

[0033] The suction assembly 10 can be, but is not limited to, a vacuum pump. The two air pipes connected to the suction assembly are respectively connected to two air paths of the suction assembly. One air path continuously draws air from the air pipe, while the other air path first draws air from the air pipe and then blows air out. When both air pipes are drawing air simultaneously, the suction cups 24 and nozzles 23 corresponding to the two air pipes can respectively create a vacuum surface between the suction holes 22 and the air guide holes 21 on the panel, allowing the sealing ring to adhere to the panel. At this time, the operator can introduce a cutting tool from outside the device to cut the sealing ring adhered to the panel, separating the ring and the cast ring. After the head is cut and separated, the ring and the topping are adsorbed into the annular groove 31 and the groove 35 respectively by the suction cup 24 and the suction nozzle 23. At this time, the air pipe corresponding to the adsorbed ring changes the air path direction, turning the suction into blowing, so that the ring adsorbed in the annular groove 31 is blown out. Finally, the suction assembly 10 is closed, and the topping can no longer be adsorbed on the panel and falls out of the groove 35. Through the above operation, the sealing ring can be separated from the ring and the topping during the adsorption process and collected separately, saving the subsequent operation of separating the ring and the topping on the sealing ring separately.

[0034] The suction cup and the suction nozzle are respectively connected to two air pipes. The suction cup 24 is sealed to the suction hole 22, and the suction nozzle 23 is sealed to the air guide hole 21. At the same time, the suction hole 22 corresponds to the position of the ring, and the air guide hole 21 corresponds to the position of the gating. Therefore, under the action of the suction assembly, the ring and the gating are controlled separately through two air paths.

[0035] The aforementioned panel may include a detachable and fixed connecting plate 20 and a limiting plate 30. An air suction groove is provided on the limiting plate 30 to limit the sealing ring pushed out by the mold core. At the same time, the air guide hole and the air suction hole are respectively provided on the connecting plate and the limiting plate 30. In this case, not only will the limiting effect on the sealing ring be not affected, but the limiting plate can also be replaced according to the size of the sealing ring, increasing the applicability of the overall device.

[0036] like Figure 1-2 As shown, the panel may include a detachable and fixed connecting plate 20 and a limiting plate 30. An air intake groove is formed on the limiting plate 30. The air intake groove is a through groove. A crescent-shaped block 34 fixed to the connecting plate is provided in the annulus formed by the air intake groove. The cavity formed between the outer surface of the crescent-shaped block and the side surface of the air intake groove can limit the sealing ring. At the same time, in this case, the limiting block 30 and the crescent-shaped block 34 can be selected and replaced according to the size of the sealing ring, increasing the applicability of the overall device.

[0037] On the side of the panel near the suction groove 31, a strip groove 33 is formed that communicates with the sealing ring groove 31. A section of the arc of the suction groove 31 coincides with the strip groove 33. The depth of the strip groove and the sealing ring groove are equal. Sensors are fixed on both the left and right surfaces of the panel. The sensors on both sides play the roles of infrared emission and reception, respectively. The function of the strip groove is to form a path between the infrared emission and reception ends of the sensors on both sides. At the same time, a section of the arc of the suction groove coincides with the strip groove 33. Therefore, when the sealing ring is pushed into the suction groove by the mold core, the sealing ring disrupts the infrared emission and reception path of the sensor. Through the above principle, the sensor can identify the sealing ring.

[0038] like Figure 6 As shown, the sealing ring suction device has three different states. First, before the sealing ring injection is completed, there is no sealing ring in the suction groove of the sealing ring suction device. After the sealing ring injection is completed, it is pushed into the suction groove by the mold core. The suction component 10 uses the suction nozzle to firmly fix the sealing ring in the suction groove. At this time, the robotic arm at the outer end cuts the sealing ring into separate rings and sprues. Then, the two air paths of the suction component blow out the rings and continuously absorb the sprues. Finally, the rings and sprues are collected separately, saving the subsequent operation of separating the rings and sprues on the sealing ring.

[0039] This invention features a novel structure and stable operation. It replaces the existing method of using a robotic arm to grasp the sealing ring with a method of sucking the sealing ring through an air suction component, increasing the force-bearing area of ​​the sealing ring and reducing the possibility of deformation. In addition, the two air paths of the suction component can simultaneously suck up the ring and the topping on the molded sealing ring on the panel, cut them with the robotic arm, and then eject them separately, reducing the difficulty of separating the ring and the topping for workers, reducing the workload of overall sealing ring processing, and facilitating the recycling of the topping.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
