Description

Technical Field

[0001] This invention relates to the field of sealing ring feeding, and more particularly to an automatic sealing ring feeding and fitting device. Background Technology

[0002] A sealing ring is a rubber product, and its material varies from soft to hard. Generally, sealing rings need to be installed in conjunction with the workpiece. However, most of the current installation is done manually, which is extremely inefficient. This is especially true when assembling sealing rings made of harder materials, as the installation is more difficult and time-consuming.

[0003] Therefore, the inventor of this invention aims to invent an automatic feeding and fitting device for sealing rings to address the above-mentioned problems. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an automatic feeding and fitting device for sealing rings.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic feeding and fitting device for sealing rings, comprising an automatic feeding component, wherein the automatic feeding component can transport the sealing ring to a horizontal conveying component, the horizontal conveying component can transport the sealing ring to an assembly station in a horizontal direction, and assemble the sealing ring with the workpiece at the assembly station, wherein the assembly station includes a primary pre-assembly component and a secondary fully assembly component, the primary pre-assembly component and the secondary fully assembly component are connected by two-stage assembly blocks, and the primary pre-assembly component can assemble the sealing ring into a primary step of the two-stage assembly blocks, and the secondary fully assembly component can assemble the sealing ring in the primary step with the workpiece.

[0006] Preferably, the automatic feeding assembly includes a feeding bin with a circular inner wall and a feeding hole at the top. A sealing ring is housed within the feeding hole. An air inlet channel is located at the bottom of the feeding bin and is horizontally positioned to blow airflow horizontally into the feeding bin. The sealing ring moves along the inner wall under the influence of the airflow and enters the feeding hole at its top. The airflow is tangential to the bottom of the circular inner wall, causing the O-ring to move along the inner wall. When it reaches the feeding hole, which is larger than the sealing ring, the sealing ring enters, thus completing the automatic feeding process and conveying the material to the horizontal conveying assembly.

[0007] Preferably, the feeding hole is located at the top of the inside of the feeding hopper, offset vertically by 0.5-2 cm in the horizontal plane, with the offset direction extending from the central vertical direction to one side of the air intake channel. The air intake channel is horizontally set, but to ensure air intake along the tangential direction, it is set slightly offset to one side, for example, as shown in the attached figure, it is set on the left side of the bottom. At the same time, the feeding hole at the top is also slightly offset to the left. This setting ensures that when the sealing ring enters the feeding hole along the inner wall, it can smoothly enter. When it continues to move, it will contact the left side wall of the feed inlet, thus blocking it and allowing the sealing ring to smoothly enter the feeding hole, ensuring timely feeding. Of course, it is necessary to ensure that the right side wall of the feeding hole is thicker than the left side wall, and the thickness does not exceed the thickness of the sealing ring, ensuring continuous feeding through the feeding hole.

[0008] Preferably, a turbulence block is also provided on the outside of the feeding hopper, and a turbulence channel is provided inside the turbulence block, with the turbulence channel leading from the outside to the inside of the feeding hopper. That is, the turbulence block can turbulentize the interior of the feeding hopper, thereby facilitating the movement of the several sealing rings stored inside. This makes it easier for the sealing rings close to the inner wall to move along the inner wall, preventing excessive accumulation of sealing rings, which could cause excessive weight on the sealing rings at the bottom, preventing them from moving smoothly along the inner wall.

[0009] Preferably, the horizontal conveying assembly includes a conveying plate disposed on top of the feeding hopper, and a conveying channel is formed between the conveying plate and the top of the feeding hopper. The conveying channel communicates with the feeding hole of the feeding hopper and is horizontally arranged.

[0010] Preferably, the conveyor plate is further provided with a conveyor block, the conveyor block having a main conveying air channel inside, and the main conveying air channel communicating with a secondary conveying air channel on the conveyor plate. Simultaneously, the secondary conveying air channel is connected to the conveying channel, and the secondary conveying air channel is inclined, with the inclination direction from the outside of the conveyor plate inwards towards the assembly station. The inclined secondary conveying air channel generates an inclined airflow, which in turn drives the small-mass sealing ring to move towards the assembly station, achieving horizontal conveying of the sealing ring.

[0011] Preferably, the primary pre-assembly component includes a pre-assembly bracket, within which a pre-assembly block is disposed. The pre-assembly block is T-shaped, with its lower end extending beyond the bottom of the pre-assembly bracket and fitted with a limiting retaining ring. A return spring is also disposed on the pre-assembly block, providing an upward force to the block. Simultaneously, the limiting retaining ring contacts the bottom end of the pre-assembly bracket. That is, the lower ends of the two-stage assembly blocks abut against the top of the pre-assembly block. When pressed down by external force, the two-stage assembly blocks move downwards together with the pre-assembly block (at which point the sealing ring at the top of the pre-assembly bracket remains stationary). Therefore, the O-ring enters the primary step of the two-stage assembly blocks, achieving pre-assembly.

[0012] Preferably, the pre-assembly bracket has a pre-assembly groove, the inner wall of the pre-assembly groove has a limiting protrusion, and the outer side of the pre-assembly block has a limiting groove, with the limiting protrusion engaging with the limiting groove. By setting the limiting protrusion vertically and the limiting groove also vertically, this engagement ensures that the pre-assembly block can move only in a vertical direction, guaranteeing the effectiveness of the pre-assembly.

[0013] Preferably, the secondary fully assembled component includes a secondary ejector block connected to a secondary ejector rod. The secondary ejector block and ejector rod are arranged in an I-shape and are located within a pre-assembly block. An I-shaped mounting groove is provided within the pre-assembly block, with both ends of the groove open. A secondary ejection cylinder is positioned directly below the secondary ejector rod. The telescopic rod of the secondary ejection cylinder contacts the secondary ejector rod, causing it to eject upwards. In other words, the secondary ejection cylinder causes the I-shaped secondary ejector block and ejector rod to eject upwards, allowing the secondary ejector block to extend beyond the surface of the pre-assembly block, thus achieving secondary assembly. The I-shape also serves as a limiting mechanism, ensuring that when the secondary ejector block is lowered to its lowest position, it is level with or slightly below the upper surface of the pre-assembly block.

[0014] Preferably, a secondary spring is provided inside the lower end of the I-shaped mounting groove, and the secondary spring is sleeved on the secondary ejector rod, and the secondary spring can exert a downward force on the secondary ejector rod. That is, it is ensured that when there is no action of the secondary ejector cylinder, the surface of the secondary ejector block is always level with or slightly lower than the surface of the pre-installed block.

[0015] Preferably, the two-stage assembly block is cylindrical and has a step in its middle. Sliding ramps are provided at both the upper and lower ends of the step, and the inclination direction of the sliding ramps is downward from the outside to the inside. Under the action of external force, the sealing ring can enter the step along the sliding ramps and then enter the workpiece set at the top of the two-stage assembly block.

[0016] Preferably, the top of the two-stage assembly block is provided with an assembly boss, which can be inserted into the workpiece, so that the outer surface of the workpiece is connected to the outer surface of the two-stage assembly block. That is, the setting of the assembly boss ensures the accurate placement of the workpiece, and at the same time facilitates the sealing ring to slide into the workpiece along the outer wall of the two-stage assembly block to complete the assembly of the sealing ring.

[0017] Preferably, an opening assembly is also provided on the pre-assembly bracket. The opening assembly includes a base plate located directly above the pre-assembly bracket and having a gap between it and the bracket, the gap communicating with the conveying channel. A through hole is provided on the base plate, and an opening ring is also provided on the base plate. The inner ring of the opening ring is the same size as and communicates with the through hole. Multiple opening blocks are arranged in a circular pattern on the outer side of the opening ring. The bottom of each opening block is hinged to the opening ring, and the opening blocks are positioned within opening grooves on the outer side of the two-stage assembly blocks. The spring holes of the multiple opening blocks are connected by coil springs, and the coil springs ensure that the opening blocks are always positioned within the opening grooves. That is, the coil springs provide a force towards the center of the multiple opening blocks.

[0018] A buffer block is also provided at the gap. One side of the buffer block is semi-circular and can match the sealing ring. A buffer waist-shaped hole is provided on the buffer block. The buffer waist-shaped hole is fitted into the buffer column above the pre-installed bracket. At the same time, the outer side of the buffer block also abuts against the buffer spring. The buffer spring exerts an inward force on the buffer block, so that the sealing ring is in the vertical axis direction of the working state. In order to protect the sealing ring, this buffer spring and buffer block are set to prevent the sealing ring from colliding with the inner wall and damaging the sealing ring when the inclined airflow blows the sealing ring, which may lead to the unqualified sealing ring on the subsequent workpiece.

[0019] Preferably, the opening groove is correspondingly provided with the opening hole, and the opening groove extends to the sliding inclined surface. At the position corresponding to the first step, the opening groove contracts inward. That is, the opening groove above the first step is inclined upward and outward, the lower opening groove is slightly inclined outward and downward, and the upper opening groove is inclined outward. This ensures that the opening block tilts outward along the opening groove, thereby allowing the sealing ring to open, facilitating assembly with the workpiece and improving assembly efficiency.

[0020] Of course, to ensure smooth operation, a cover can be installed on the outside of the pre-installed bracket.

[0021] The tooling is also equipped with photoelectric sensors. One sensor is installed in the conveying channel to detect whether the sealing ring is fed through the feeding hole; another sensor is installed above the pre-assembled block to detect whether the sealing ring is in place, so as to facilitate the operation of the first-stage pre-assembled components and ensure the effectiveness of the operation; and a third sensor is installed above the second-stage ejection cylinder to facilitate the identification of whether the second-stage ejection cylinder is performing the second-stage ejection.

[0022] The beneficial effect of the automatic feeding and assembly device for sealing rings of the present invention is that by setting this tooling, the automatic feeding and assembly of sealing rings is realized, which improves the assembly efficiency. At the same time, several sets of tooling can be set in parallel to improve the degree of automation. Attached Figure Description

[0045] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0046] See appendix Figure 1-14 As shown, an automatic feeding and fitting device for sealing rings in this embodiment includes an automatic feeding component 3. The automatic feeding component 3 can transport the sealing ring 1 to a horizontal conveying component 4. The horizontal conveying component 4 can transport the sealing ring 1 to an assembly station in a horizontal direction, and assemble the sealing ring 1 with the workpiece 2 at the assembly station. The assembly station includes a primary pre-assembly component 5 and a secondary fully assembly component 6. The primary pre-assembly component 5 and the secondary fully assembly component 6 are connected by two-stage assembly blocks 7. The primary pre-assembly component 5 can assemble the sealing ring 1 into the primary step 71 of the two-stage assembly blocks 7, and the secondary fully assembly component 6 can assemble the sealing ring 1 in the primary step 71 with the workpiece 2.

[0047] See Figure 7-9 The automatic feeding assembly 3 includes a feeding bin 31 with a circular inner wall and a feeding hole 32 at the top. A sealing ring 1 is installed in the feeding hole 32. An air inlet channel 33 is located at the bottom of the feeding bin 31. The air inlet channel 33 is horizontally positioned and blows airflow horizontally into the feeding bin 31. The sealing ring 1 moves along the inner wall under the influence of the airflow and enters the feeding hole 32 at the top. The airflow is tangential to the bottom of the circular inner wall, causing the O-ring to move along the inner wall. When it reaches the feeding hole 32, which is larger than the sealing ring 1, the sealing ring 1 enters the feeding hole 32, thus completing the automatic feeding and conveying the material to the horizontal conveying assembly 4.

[0048] See appendix Figure 3The feeding hole 32 is located at the top inside the feeding bin 31, offset vertically by 0.5-2cm in the horizontal plane, with the offset direction extending from the vertical center to one side of the air intake channel 33. The air intake channel 33 is horizontally set, but to ensure air intake along the tangential direction, it is set slightly offset to one side, for example, as shown in the attached figure, it is set on the left side of the bottom. At the same time, the top feeding hole 32 is also slightly offset to the left. This setting ensures that when the sealing ring 1 enters the feeding hole 32 along the inner wall, it can smoothly enter. When it continues to move, it will contact the left side wall of the feed inlet, thus blocking it and allowing the sealing ring 1 to smoothly enter the feeding hole 32, ensuring timely feeding. Of course, it is necessary to ensure that the right side wall of the feeding hole 32 is thicker than the left side wall, and the thickness does not exceed the thickness of the sealing ring 1, ensuring continuous feeding of the feeding hole 32.

[0049] See appendix Figure 8-9 A turbulence block 34 is also provided on the outside of the feeding hopper 31, and a turbulence channel 35 is provided inside the turbulence block 34, which leads from the outside to the inside of the feeding hopper 31. That is, the turbulence block can turbulentize the inside of the feeding hopper 31, thereby facilitating the movement of the sealing rings 1 stored inside. This makes it easier for the sealing rings 1 close to the inner wall to move along the inner wall, preventing excessive accumulation of sealing rings 1, which would cause excessive gravity on the sealing rings 1 located at the bottom, thus preventing them from moving smoothly along the inner wall.

[0050] See appendix Figure 3 The horizontal conveying assembly 4 includes a conveying plate 41, which is disposed on the top of the feeding hopper 31 and forms a conveying channel 42 between the conveying plate 41 and the top of the feeding hopper 31. The conveying channel 42 communicates with the feeding hole 32 of the feeding hopper 31 and is horizontally arranged.

[0051] See appendix Figure 3 The conveyor plate 41 is also equipped with a conveyor block 43. The conveyor block 43 has a main conveying air passage 44 inside, which is connected to a secondary conveying air passage 45 on the conveyor plate 41. The secondary conveying air passage 45 is also connected to the conveying channel 42. The secondary conveying air passage 45 is inclined, with the inclination direction from the outside of the conveyor plate 41 inwards towards the assembly station. The inclined secondary conveying air passage 45 generates an inclined airflow, which drives the small-mass sealing ring 1 to move towards the assembly station, achieving horizontal conveying of the sealing ring 1.

[0052] See appendix Figure 4The first-stage pre-assembly component 5 includes a pre-assembly bracket 51, within which a pre-assembly block 52 is disposed. The pre-assembly block 52 is T-shaped, with its lower end extending beyond the bottom of the pre-assembly bracket 51 and fitted with a limiting ring 53. A return spring 54 is also disposed on the pre-assembly block 52, providing an upward force. Simultaneously, the limiting ring 53 contacts the bottom end of the pre-assembly bracket 51. That is, the lower ends of the two-stage assembly blocks 7 abut against the top of the pre-assembly block 52. When pressed down by external force, the two-stage assembly blocks 7 move downwards along with the pre-assembly block 52 (at this time, the sealing ring 1 located at the top of the pre-assembly bracket 51 remains stationary). Therefore, the O-ring will enter the first-stage step 71 of the two-stage assembly blocks 7, achieving pre-assembly.

[0053] See appendix Figure 10 The pre-installation bracket 51 has a pre-installation groove 55, and the inner wall of the pre-installation groove 55 has a limiting protrusion 56. At the same time, the outer side of the pre-installation block 52 has a limiting groove 57, and the limiting protrusion 56 can cooperate with the limiting groove 57. The limiting protrusion 56 is set in a vertical direction, and the limiting groove 57 is also vertical. This cooperation ensures that the pre-installation block 52 can move only in a vertical direction, thus ensuring the effectiveness of the pre-installation.

[0054] See appendix Figure 4 The secondary fully assembled component 6 includes a secondary ejector block 61, which is connected to a secondary ejector rod 62. The secondary ejector block 61 and the secondary ejector rod 62 are arranged in an I-shape. The secondary ejector block 61 and the secondary ejector rod 62 are located in a pre-assembly block 52. An I-shaped mounting groove 63 is provided in the pre-assembly block 52, and both the upper and lower ends of the I-shaped mounting groove 63 are open. A secondary ejector cylinder 64 is provided directly below the secondary ejector rod 62. The telescopic rod of the secondary ejector cylinder 64 can contact the secondary ejector rod 62 and push the secondary ejector rod 62 upward. That is, the secondary ejection cylinder 64 causes the secondary ejection block 61 and the secondary ejection rod 62, which are arranged in an I-shape, to be ejected upward, so that the secondary ejection block 61 can exceed the surface of the pre-assembly block 52, thus realizing secondary assembly. At the same time, the I-shape setting can play a limiting role, ensuring that when it moves down to the lowest position, the secondary ejection block 61 is level with or slightly lower than the upper surface of the pre-assembly block 52.

[0055] See appendix Figure 14 A secondary spring 65 is installed inside the lower end of the I-shaped mounting groove 63, and the secondary spring 65 is sleeved on the secondary ejector rod 62, and the secondary spring 65 can exert a downward force on the secondary ejector rod 62. This ensures that when the secondary ejector cylinder 64 is not in action, the surface of the secondary ejector block 61 is always level with or slightly lower than the surface of the pre-installed block 52.

[0056] See appendix Figure 11The two-stage assembly block 7 is cylindrical, with a first-stage step 71 in the middle. Sliding ramps 72 are provided at the upper and lower ends of the first-stage step 71, and the inclination direction of the sliding ramps 72 is downward from the outside to the inside. Under the action of external force, the sealing ring 1 can enter the first-stage step 71 along the sliding ramp 72, and then enter the workpiece 2 set at the top of the two-stage assembly block 7 along the sliding ramp 72.

[0057] See appendix Figure 11 The top of the two-stage assembly block 7 is provided with an assembly boss 73, which can be inserted into the workpiece 2, so that the outer surface of the workpiece 2 is connected to the outer surface of the two-stage assembly block 7. That is, the setting of the assembly boss 73 ensures the accurate placement of the workpiece 2, and at the same time facilitates the sealing ring 1 to slide into the workpiece 2 along the outer wall of the two-stage assembly block 7 to complete the assembly of the sealing ring 1.

[0058] See appendix Figure 5 An opening assembly 8 is also provided on the pre-assembly bracket 51. The opening assembly 8 includes a base plate 81, which is located directly above the pre-assembly bracket 51 and has a gap with it. The gap communicates with the conveying channel 42. A through hole 82 is provided on the base plate 81, and an opening ring 83 is also provided on the base plate 81. The inner ring of the opening ring 83 is the same size as and communicates with the through hole 82. Multiple opening blocks 84 are arranged in a circular shape on the outer side of the opening ring 83. The bottom of the opening blocks 84 is hinged to the opening ring 83, and the opening blocks 84 are set in the opening groove 74 on the outer side of the two-stage assembly block 7. The spring holes 85 of the multiple opening blocks 84 are connected by coil springs 86, and the coil springs 86 can keep the opening blocks 84 always within the opening groove 74. That is, the coil springs 86 can provide a force to the multiple opening blocks 84 towards the center.

[0059] See appendix Figure 6 A buffer block 87 is also provided at the gap. One side of the buffer block 87 is semi-circular and can match the sealing ring 1. A buffer waist-shaped hole 88 is provided on the buffer block 87. The buffer waist-shaped hole 88 is fitted inside the buffer column 89 above the pre-installed bracket 51. At the same time, the outer side of the buffer block 87 also abuts against the buffer spring 810. The buffer spring 810 exerts an inward force on the buffer block 87, so that the sealing ring 1 is in the vertical axis direction of the working state. In order to protect the sealing ring 1, this buffer spring 810 is set in conjunction with the buffer block 87 to prevent the sealing ring 1 from colliding with the inner wall and damaging the sealing ring 1 when the inclined airflow blows it. This may lead to the sealing ring 1 on the subsequent workpiece 2 being unqualified.

[0060] The opening groove 74 is correspondingly set to the opening hole, and the opening groove 74 extends to the sliding inclined surface 72. At the position corresponding to the first step 71, the opening groove 74 contracts inward. That is, the opening groove 74 above the first step 71 is inclined upward and outward, the lower opening groove 74 is slightly inclined outward and downward, and the upper opening groove 74 is inclined outward. This ensures that the opening block 84 is inclined outward along the opening groove 74, thereby allowing the sealing ring 1 to open, facilitating assembly with the workpiece 2 and improving assembly efficiency.

[0061] Of course, to ensure smooth operation, a cover can be installed on the outside of the pre-installed bracket 51.

[0062] The tooling is also equipped with photoelectric sensors 9. One sensor is installed in the conveying channel 42 to detect whether the sealing ring 1 is fed through the feeding hole 32; another sensor is installed above the pre-assembly block 52 to detect whether the sealing ring 1 is in place, so as to facilitate the operation of the first-stage pre-assembly component 5 and ensure the effectiveness of the operation; and a third sensor is installed above the second-stage ejection cylinder 64 to facilitate the identification of whether the second-stage ejection cylinder 64 is performing the second-stage ejection.

[0063] The beneficial effect of an automatic feeding and assembly device for sealing rings is that by setting this tooling, the feeding and assembly of sealing rings 1 is automated, improving the assembly efficiency. At the same time, several sets of tooling can be set in parallel, which improves the degree of automation.

[0064] The basic working principle is as follows: First, the automatic feeding component 3 automatically feeds the sealing ring 1, and the horizontal conveying component 4 conveys the sealing ring 1 in the horizontal direction until it is conveyed to the assembly station.

[0065] Second, the workpiece 2 is fitted into the assembly boss 73 on the top of the two-stage assembly block 7. At this time, the outer surface of the workpiece 2 is connected to the surface of the two-stage assembly block 7. When the external force presses down on the workpiece 2, the workpiece 2 and the two-stage assembly block 7 move downward at the same time. At this time, the sealing ring 1 is stationary. During the downward movement, the sealing ring 1 will be fitted onto the lower end of the two-stage assembly block 7 and slide into the first step 71 along with the inclined plane 72. At this time, the external force disappears. Under the action of the return spring 54, the pre-assembled block 52 is reset and pushes out the two-stage assembly block 7.

[0066] Third, due to the presence of the coil spring 86, the edge of the opening block 84 is pressing against the sealing ring 1. The secondary ejection cylinder 64 causes the I-shaped secondary ejection block 61 and the secondary ejection rod 62 to be ejected along the center line. When ejected, the two-stage assembly block 7 will extend slightly upwards, and the opening block 84 will remain stationary in the horizontal direction, which will cause the opening block 84 to be located below the sealing ring 1.

[0067] Fourth, at this time, the opening block 84 is located below the sealing ring 1 on the first step 71, and the second step of pressing down is performed again. The process of being below the first step 71 is the same as the second step. During this process, because the opening block 84 is always moving inward under the action of the coil spring 86, it moves along the opening slide 74. Since the opening slide 74 is inclined outward, it opens the sealing ring 1. As the pressing process proceeds, the sealing ring 1 enters the workpiece 2 along the communicating surface.

[0068] Repeating this process twice—second, third, and fourth—achieved continuous feeding of sealing ring 1.

[0069] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They are not intended to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
