Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sealing ring production, in particular to a feeding and discharging integrated machine for sealing ring production. BACKGROUND

[0002] In the sealing ring production and processing process, burrs are common defects, mainly caused by improper material flow, mold gap or process parameter control, and after the sealing ring is produced, secondary processing is required to clean the burrs on the outer ring of the sealing ring.

[0003] Currently, the burr cleaning methods on the outer ring of the sealing ring generally have two methods of frozen trimming and laser cutting. The principle of frozen trimming is that the sealing rubber ring is rapidly low-temperature brittle, and then removed by mechanical vibration. This removal method is suitable for large quantities and low precision requirements in production and processing.

[0004] Laser cutting uses a high-power density laser beam to focus on the surface of the burr, so that the burr is instantaneously melted, vaporized or ablated, thereby realizing non-contact precision cutting, which can accurately cut off the burr on the outer ring of the sealing ring. The premise of accurate cutting is the accuracy of the position of the sealing ring after feeding, and the feeding and placement state and position of the sealing ring will directly affect the cutting position. If the feeding and placement state and position do not meet the requirements, the cutting process will damage the sealing ring, the sealing ring regularity will not meet the standards, or the burr cutting will not be thorough, and the residual burr will directly affect the quality of the sealing ring product.

[0005] Therefore, in view of the above problems, a feeding and discharging integrated machine for sealing ring production is provided. SUMMARY

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0042] Reference Figure 1 - Figure 11 A material handling machine for producing sealing rings includes a turntable 1. Multiple sets of support rods 2 are arranged in a circumferential array at an eccentric position on the turntable 1. Each support rod 2 in each set extends upward and the upper end of the support rod 2 in each set is bent inward to form a step 3. Multiple steps 3 in the same set jointly support the sealing ring 101.

[0043] A cutting assembly and a feeding assembly are provided on the outer side of the turntable 1; the cutting assembly is used to cut off the burrs on the outer ring of the sealing ring 101; the feeding assembly includes a horizontal plate 4 that rotates alternately in the forward and reverse directions, and a cylinder 5 is provided at both ends of the horizontal plate 4. Multiple fixing rods 6 are arranged in a circular array at the output end of each cylinder 5, and an arc-shaped rod 7 is provided at the end of each fixing rod 6. A claw 8 is provided at the end of the arc-shaped rod 7.

[0044] Multiple second cylinders 9 are arranged in a circular array around the output end of each first cylinder 5. An arc plate 10 is fixed to the output end of each second cylinder 9. The arc plate 10 is used to compress the arc rod 7.

[0045] The horizontal plate 4 is driven to rotate by the geared motor 11, and the geared motor 11 is controlled by the PLC, which can realize the alternating rotation of the horizontal plate 4 in the forward and reverse directions. The end shell of the geared motor 11 is fixed to the ground or the operating table by the L-shaped rib plate 12; the first cylinder 5 and the second cylinder 9 are also controlled by the PLC.

[0046] In this embodiment of the invention, the turntable 1 is driven by a drive component, which is driven by a servo motor. The servo motor is controlled by a PLC, enabling intermittent rotation of the servo motor, thereby driving the intermittent rotation of the turntable 1. In this embodiment, as shown... Figure 4 As shown, turntable 1 rotates intermittently clockwise, and the cutting assembly is positioned as follows: Figure 4 The feeding assembly is located at the top center, such as... Figure 4 The middle right position, while the feeding position is as follows: Figure 4 Lower middle position;

[0047] The specific operation of this integrated loading and unloading machine is as follows:

[0048] Step 1: Loading. When the turntable 1 stops rotating, place the sealing ring 101 on the multiple support rods 2 in the same group and press the sealing ring 101 firmly so that the lower surface of the sealing ring 101 sits on the step 3. Since the multiple support rods 2 in the same group are arranged in a circumferential array and the upper surface of the step 3 on each support rod 2 is on the same horizontal plane, after the lower surface of the sealing ring 101 sits on the step 3, the sealing ring 101 is in a horizontal state. Moreover, the diameter of the circle formed by the outer walls of the multiple support rods 2 in the same group is the same as the inner diameter of the sealing ring 101. That is, the multiple support rods 2 in the same group will not squeeze the sealing ring 101, and the sealing ring 101 can maintain its original roundness and diameter.

[0049] Step 2: Cutting. Turntable 1 transfers the finished sealing ring 101 to the cutting component. The cutting component cuts and removes the burrs on the outer ring of the sealing ring 101.

[0050] Step 3: Unloading. After the flash is cut and cleaned, turntable 1 continues to rotate, transferring the sealing ring 101 to the unloading assembly position. At this time, one end of the horizontal plate 4 is above the sealing ring 101. The first cylinder 5 at one end of the horizontal plate 4 drives the fixing rod 6, the arc rod 7, the claw 8, the second cylinder 9, and the arc plate 10 to move down synchronously. The lower surface of the claw 8 abuts against the sealing ring 101. The claw 8 deflects upward around the connection point with the arc rod 7 and passes over the sealing ring 101, placing itself below the sealing ring 101. A torsion spring is installed at the connection point between the claw 8 and the arc rod 7. The torque of the torsion spring causes the claw 8 to rotate and reset, and the upper surface of the end of the claw 8 is placed on the lower surface of the sealing ring 101. Then, the first cylinder 5 drives the fixing rod 6, the arc rod 7, and the claw 8 to move down synchronously. The second cylinder 9 and the arc plate 10 move upwards synchronously, the chuck 8 lifts the sealing ring 101 and takes it away. Then the reduction motor 11 drives the horizontal plate 4 to rotate, rotating the taken-away sealing ring 101 to the initial position at the other end of the horizontal plate 4. Then the second cylinder 9 is executed, and the second cylinder 9 drives the arc plate 10 to move upwards. The arc plate 10 no longer squeezes the arc rod 7. The arc rod 7 and the fixed rod 6 are also connected together by a torsion spring. Under the torsion of the torsion spring, multiple arc rods 7 connected to the same first cylinder 5 expand outwards synchronously. At the same time, the chuck 8 disengages from the sealing ring 101. The sealing ring 101 loses the support of the chuck 8 and falls under its own weight. At this time, the unloading of the sealing ring 101 can be completed.

[0051] Simply repeat steps one, two, and three thereafter.

[0052] During the loading process, because multiple support rods 2 in the same group are arranged in a circular array, and the upper surface of the step 3 on each support rod 2 is on the same horizontal plane, the lower surface of the sealing ring 101 is located behind the step 3, and the sealing ring 101 is in a horizontal state. Moreover, the diameter of the circle formed by the outer walls of the multiple support rods 2 in the same group is the same as the inner diameter of the sealing ring 101. That is, the multiple support rods 2 in the same group will not squeeze the sealing ring 101, and the sealing ring 101 can maintain its original roundness and diameter. Therefore, for the subsequent laser cutting process, the flash on the outer ring of the sealing ring 101 can be accurately cut off. At the same time, the loading process is simple to operate and does not require a lot of labor. In the unloading step, through the automated execution of the unloading component and the intermittently rotating turntable 1, the sealing ring 101 can be removed quickly and stably, reducing manual intervention, reducing the chance of contact between humans and machines, improving safety, and reducing labor costs.

[0053] Reference Figure 1 - Figure 13 The cutting assembly includes a third cylinder 13, and a lifting plate 14 is fixedly connected to the output end of the third cylinder 13. A cutting head 15 of a laser cutting machine is symmetrically fixedly connected to the lifting plate 14.

[0054] Rotary holes are evenly distributed at eccentric positions on the turntable 1. A rotating body 16 is rotatably connected in each rotary hole. A set of support rods 2 is provided on each rotating body 16. A toothed ring 17 is fixedly connected to the outer ring of the lower end of each rotating body 16.

[0055] A guide rail 18 is fixedly connected to the outer wall of the cylinder body of the No. 3 cylinder 13. A rack 19 is slidably connected inside the guide rail 18. The rack 19 is used to mesh with the gear ring 17 and drive the rotating body 16 to rotate.

[0056] In this embodiment, the designed cutting assembly uses a laser to cut the burrs on the sealing ring 101; the length of the guide rail 18 is greater than twice the length of the rack 19, and the meshing length between the rack 19 and the toothed ring 17 can achieve a rotation angle of more than 180 degrees for the toothed ring 17.

[0057] Specifically, a lead screw is internally threaded onto the rack 19, and the end of the lead screw is rotatably connected to the end of the guide rail 18. A motor capable of driving the rack to rotate forward and reverse alternately is connected to the end of the lead screw. Initially, the rack 19 is located at one end inside the guide rail 18, as follows: Figure 4 As shown, at one end of the guide rail 18, space is left for the gear ring 17 to revolve around the turntable 1. When the turntable 1 transfers the sealing ring 101 to the position opposite to the cutting assembly, the gear ring 17 corresponding to the sealing ring 101 below it does not engage with the rack 19. Then, the third cylinder 13 is driven, which moves the cutting head 15 downward. When the cutting head 15 moves to the specified height, it executes the laser to cut the flash, and at the same time drives the lead screw to rotate. The lead screw pushes the rack 19 to move, and the rack 19 engages with the gear ring 17. The linearly moving rack 19 rubs against the gear ring 17. The toothed ring 17 rotates, driving the sealing ring 101 to rotate via the rotating body 16. As the sealing ring 101 rotates, the cutting head 15 cuts the flash on the outer ring of the sealing ring 101. With two symmetrically arranged cutting heads 15, the sealing ring 101 only needs to rotate 180 degrees to completely cut the flash on its outer ring with laser. To avoid any residue from the cutting, when the rack 19 moves from the right end of the guide rail 18 to the left end, the rack 19 can drive the toothed ring 17 to rotate by an angle greater than 180 degrees. That is, the sealing ring 101 achieves a rotation of more than 180 degrees, resulting in a better cutting and cleaning effect.

[0058] Reference Figure 6 - Figure 8 Each of the rotating bodies 16 has a chip removal hole 20, and each set of support rods 2 is installed in each chip removal hole 20. The lower end of the support rod 2 is fixed to the inner side wall of the chip removal hole 20.

[0059] Chip removal holes 20 are provided on each rotating body 16. After the flash is cut off by laser, the flash detaches and falls down along the chip removal holes 20 to prevent the flash from accumulating on the rotating body 16 or hindering the rotation of the rotating body 16.

[0060] Reference Figure 1 - Figure 5 ,as well as Figure 15 The turntable 1 is provided with a positioning component on its outer side, and the positioning component includes a fourth cylinder 21. The output end of the fourth cylinder 21 is fixedly connected to a pressure plate 22. Multiple pressure rods 23 are arranged in a circumferential array on the lower surface of the end of the pressure plate 22. The lower ends of the multiple pressure rods 23 are fixedly connected to a pressure ring 24. The pressure ring 24 is used to press the sealing ring 101 onto the step 3.

[0061] In this embodiment, the positioning component is used to assist in feeding the sealing ring 101. Firstly, it presses the sealing ring 101 into place, and secondly, it reduces the labor intensity of manual feeding. Specifically, during manual feeding, the sealing ring 101 only needs to be placed on the upper end of the multiple support rods 2 in the same group; there is no need to forcefully press the sealing ring 101 onto the step 3, thus reducing the labor intensity of manual feeding. When the turntable 1 transfers the sealing ring 101 to a position opposite to the pressure ring 24, the fourth cylinder 21 drives the pressure ring 24 to move downwards. The upper end of the support rod 2 is placed on the inner ring of the pressure ring 24, and the lower end face of the pressure ring 24 presses down on the sealing ring 101, pressing the sealing ring 101 onto the step 3. When the pressure ring 24 presses down on the sealing ring, it presses the sealing ring 101 horizontally, ensuring that the sealing ring 101 can be stably positioned on the step 3. This also helps in the accurate feeding of the sealing ring 101 and subsequent precise laser cutting.

[0062] Reference Figure 15 Each of the pressure rods 23 includes a fixed tube 25 fixed to the lower end surface of the pressure plate 22, a spring is provided inside the fixed tube 25, a buffer rod 26 is fixed to the end of the spring, and a pressure ring 24 is fixed to the lower end of the plurality of buffer rods 26.

[0063] The pressure rod 23 is a telescopic structure. Specifically, when the fourth cylinder 21 applies downward pressure, the buffer rod 26 compresses the spring to buffer and protect the pressure on the sealing ring 101, thereby buffering and protecting the support rod 2 so that the support rod 2 will not deform after being subjected to the pressure of the pressure ring 24 multiple times, which would affect the accuracy of feeding the sealing ring 101.

[0064] Reference Figure 7 and Figure 8 Each of the support rods 2 has an arc-shaped plate 27 at its upper end, and each plate 27 has a ramp 28 at its upper outer edge for the sealing ring 101 to slide into the step 3.

[0065] The arc-shaped plate 27 increases the contact area between the support rod 2 and the inner ring of the sealing ring 101. The outer surface of the plate 27 contacts the inner ring of the sealing ring 101 and is used to expand the sealing ring 101. For some deformed sealing rings 101, the sealing ring 101 can be expanded to make the sealing ring 101 more rounded. During subsequent laser cutting, the flash on the outer ring of the sealing ring 101 can also be accurately cut. Furthermore, a slope 28 is set on the upper edge of the plate 27 to increase the possibility of the sealing ring 101 being fitted onto the plate 27. During the process of manually fitting the deformed sealing ring 101 onto the plate 27, it is easier to achieve the feeding of the sealing ring 101.

[0066] Reference Figure 12 - Figure 14 A cleaning component is provided between the cutting component and the unloading component. The cleaning component is used to clean and remove the cut-off burrs from the support rod 2. The cleaning component includes a cover plate 29. Multiple air nozzles 30 are provided on the lower surface of the cover plate 29. A vertical pipe 31 is provided above the cover plate 29. The vertical pipe 31 is connected to the air nozzles 30. A connecting plate 32 is fixedly connected to the upper surface of the cover plate 29. The connecting plate 32 is fixedly connected to the lifting plate 14.

[0067] The cleaning components are designed to clean the burrs that fall off during cutting. Specifically, the vertical pipe 31 is connected to an external air pump through a pipe. The air pump continuously injects gas into the vertical pipe 31 and discharges it from multiple air nozzles 30. When the third cylinder 13 moves the lifting plate 14 down, the lifting plate 14 moves the cover plate 29 down through the connecting plate 32. The air nozzles 30 on the lower surface of the cover plate 29 approach the chip discharge hole 20. The gas impacts the burrs remaining on the rotating body 16 and the combustion waste generated by laser cutting rubber, making the cleaning more thorough.

[0068] Reference Figure 12 - Figure 14 The outer ring of the vertical pipe 31 is fitted with a sleeve 33, and the lower half of the inner ring of the sleeve 33 is provided with a cavity 34. The cavity 34 is connected to an external air pump through a hose 35. A crossbeam 36 is fixedly connected to the outer ring of the sleeve 33 and is fixedly connected to the cylinder body of the third cylinder 13. An air inlet 37 is provided on the outer ring of the vertical pipe 31.

[0069] The sleeve 33 is used to control the intermittent discharge of gas. Specifically, in the initial state, the air inlet 37 is staggered from the cavity 34, as shown below. Figure 14 As shown, the air inlet 37 is located above the cavity 34. When the lifting plate 14 moves the cover plate 29 down through the connecting plate 32, when the cover plate 29 moves down to the specified height position, the air inlet 37 on the vertical pipe 31 is opposite to the cavity 34. At this time, the gas in the cavity 34 is injected into the vertical pipe 31 along the air inlet 37 and discharged from multiple jet nozzles 30 for cleaning.

[0070] When the lifting plate 14 moves the cover plate 29 upward to reset to the initial state, the air inlet 37 on the vertical pipe 31 moves upward, and the air inlet 37 is once again misaligned with the cavity 34. The inner wall of the upper part of the sleeve 33 blocks the air inlet 37 again, and the side wall of the vertical pipe 31 blocks the cavity 34.

[0071] Intermittent control of gas emissions and efficient, low-energy-consumption chip removal methods enable on-demand gas injection, avoiding energy waste caused by continuous gas supply.

[0072] Reference Figure 9 - Figure 11 Each of the claws 8 has a bevel 38 at its lower edge.

[0073] An inclined surface 38 is provided on the jaw 8. When the jaw 8 squeezes the sealing ring 101 at the end, the upper edge of the outer ring of the sealing ring 101 squeezes the inclined surface 38, so that the jaw 8 can quickly and easily pass over the sealing ring 101 and be placed below the sealing ring 101. The unloading component quickly grasps the sealing ring 101, improving the overall efficiency of the unloading process.

[0074] Reference Figure 7 Each of the rotating bodies 16 has an flared inner edge on its upper surface; the inner edge of the upper surface of the rotating body 16 is the upper edge of the chip removal hole 20, which increases the chip removal inlet, allowing more burrs to fall into the chip removal hole 20 and be discharged, reducing the amount of burrs remaining in the turntable 1 or the rotating hole, and facilitating the cleaning of burrs.

[0075] Working principle: The specific operation of this integrated loading and unloading machine is as follows:

[0076] Step 1: Loading. When the turntable 1 stops rotating, place the sealing ring 101 on the multiple support rods 2 in the same group and press the sealing ring 101 firmly so that the lower surface of the sealing ring 101 sits on the step 3. Since the multiple support rods 2 in the same group are arranged in a circumferential array and the upper surface of the step 3 on each support rod 2 is on the same horizontal plane, after the lower surface of the sealing ring 101 sits on the step 3, the sealing ring 101 is in a horizontal state. Moreover, the diameter of the circle formed by the outer walls of the multiple support rods 2 in the same group is the same as the inner diameter of the sealing ring 101. That is, the multiple support rods 2 in the same group will not squeeze the sealing ring 101, and the sealing ring 101 can maintain its original roundness and diameter.

[0077] Step 2: Cutting. Turntable 1 transfers the finished sealing ring 101 to the cutting component. The cutting component cuts and removes the burrs on the outer ring of the sealing ring 101.

[0078] Step 3: Unloading. After the flash is cut and cleaned, turntable 1 continues to rotate, transferring the sealing ring 101 to the unloading assembly position. At this time, one end of the horizontal plate 4 is above the sealing ring 101. The first cylinder 5 at one end of the horizontal plate 4 drives the fixing rod 6, the arc rod 7, the claw 8, the second cylinder 9, and the arc plate 10 to move down synchronously. The lower surface of the claw 8 abuts against the sealing ring 101, deflects upward and passes over the sealing ring 101, and is placed below the sealing ring 101. A torsion spring is set at the connection position between the claw 8 and the arc rod 7. The torque of the torsion spring causes the claw 8 to rotate and reset, and the upper surface of the end of the claw 8 is placed on the lower surface of the sealing ring 101. Then, the first cylinder 5 drives the fixing rod 6, the arc rod 7, the claw 8, the second cylinder 9, and the arc plate 10 to move up synchronously. The chuck 8 lifts the sealing ring 101 and removes it. Then, the reduction motor 11 drives the horizontal plate 4 to rotate, rotating the removed sealing ring 101 to its initial position at the other end of the horizontal plate 4. Next, the second cylinder 9 is activated, driving the arc plate 10 to move upward. The arc plate 10 no longer presses against the arc rod 7. The arc rod 7 and the fixed rod 6 are also connected by a torsion spring. Under the torsion of the torsion spring, multiple arc rods 7 connected to the same first cylinder 5 simultaneously unfold outward. At the same time, the chuck 8 disengages from the sealing ring 101. The sealing ring 101 loses the support of the chuck 8 and falls under its own weight. At this point, the unloading of the sealing ring 101 is completed. Steps one, two, and three can be repeated.
