Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1As shown, the first embodiment provided in this application is an air compressor end cover assembly device, including an end cover feeding mechanism 1, a frame 2, a transfer mechanism 3 disposed between the end cover feeding mechanism 1 and the frame 2, and also including an oil distribution pipe feeding mechanism 4, an oil distribution pipe and end cover assembly mechanism 5, a pressure relief valve feeding assembly mechanism 6, and a discharge line 7 disposed on the frame 2. The oil distribution pipe feeding mechanism 4 is used to provide an oil distribution pipe 200, the oil distribution pipe and end cover assembly mechanism 5 is used to assemble the oil distribution pipe 200 with the end cover, the pressure relief valve feeding assembly mechanism 6 is used to provide a pressure relief valve 300 and end cover assembly, and the transfer mechanism 3 is used to transfer the end cover from the end cover feeding mechanism 1 to the oil distribution pipe and end cover assembly mechanism 5, transfer the end cover from the oil distribution pipe and end cover assembly mechanism 5 to the pressure relief valve feeding assembly mechanism 6, and transfer the finished product from the pressure relief valve feeding assembly mechanism 6 to the discharge line 7.

[0030] In actual use, the end cap is provided by the end cap feeding mechanism 1, and then the end cap is transferred to the oil separator pipe and end cap assembly mechanism 5 for positioning by the transfer mechanism 3. Then, the oil separator pipe feeding mechanism 4 places the oil separator pipe 200 to be assembled into the positioned end cap to achieve pre-assembly of the end cap and oil separator pipe 200. Then, the oil separator pipe and end cap assembly mechanism 5 presses the pre-assembled end cap and oil separator pipe 200 together to form a semi-finished product. Then, the semi-finished product is transferred to the pressure relief valve feeding and assembly mechanism 6 for positioning by the transfer mechanism 3. The pressure relief valve 300 is assembled on the end cap by the pressure relief valve feeding and assembly mechanism 6 to form a finished product. Then, the finished product is transferred from the pressure relief valve feeding and assembly mechanism 6 to the unloading line 7 by the transfer mechanism 3.

[0031] In the above design, the entire assembly device can automatically assemble the end cap assembly with high efficiency.

[0032] Specifically: such as Figure 1 As shown, the end cap feeding mechanism 1 includes a first frame 11, a first conveyor 12 mounted on the first frame 11, and several trays 13. The first conveyor 12 is used to transport the trays 13, and the trays 13 are used to place the end caps.

[0033] In actual use, the end cap is placed manually in the tray 13, and then the tray 13 is transported from one end to the side near the transfer mechanism 3 by the No. 1 line 12 and then the transport is stopped. Then the transfer mechanism 3 transfers the end cap in the tray 13 to the oil separator pipe and end cap assembly mechanism 5.

[0034] In the above design, the structural design and specific implementation of the end cap feeding mechanism 1 can effectively place multiple end caps in the tray 13 at one time, and use the tray 13 to place several end caps on one side of the transfer mechanism 3, so that the transfer mechanism 3 can pick them up.

[0035] Specifically: such as Figure 2 and Figure 3As shown, the oil distribution pipe feeding mechanism 4 includes a first vibratory plate 41 mounted on the frame 2, a first direct vibrator 42 connected to the first vibratory plate 41, a first distributor 43 connected to the first direct vibrator 42, a first oil spraying assembly 44 mounted on the first distributor 43, and a first transfer assembly 45 mounted on the frame 2. The first oil spraying assembly 44 includes a housing 441, a positioning seat 443 mounted inside the housing 441 and provided with a vertical positioning hole 401, a plurality of spray pipes 442 arranged circumferentially along the vertical positioning hole 401 on the positioning seat 443, and a power pump mounted on the first distributor 43 that supplies liquid to the spray pipes 442. The positioning seat 443 is also provided with a flow channel that communicates with the lower end of the vertical positioning hole 401.

[0036] In actual use, the oil distribution pipe 200 is vibrated to the first vertical vibrator 42 by the first vibrating plate 41. The first vertical vibrator 42 vibrates the oil distribution pipe 200 to the first distributor 43. Then, the first transfer component 45 clamps the oil distribution pipe 200 in the first distributor 43 and transfers it to the first oil spraying component 44 for oil spraying. At this time, the oil distribution pipe 200 extends into the vertical positioning hole 401. The outer wall of the oil distribution pipe 200 is sprayed with oil through the spray pipe 442, making the outer wall of the oil distribution pipe 200 more lubricated due to the oil stains. After the oil is sprayed, the first transfer component 45 pre-installs the oil distribution pipe 200 in the end cap. The oil sprayed from the spray pipe 442 flows along the flow channel into the box 441.

[0037] In the above design, the structural design and specific implementation of the oil distribution pipe feeding mechanism 4 facilitate the spraying of oil and feeding of oil on the oil distribution pipe 200. By spraying oil on the outer wall of the oil distribution pipe 200, the friction between the oil distribution pipe 200 and the end cap during assembly can be reduced.

[0038] Specifically: such as Figure 3 As shown, the feeding direction of the first linear vibrator 42 is the Y-axis direction. The first distributor 43 includes a first support frame 431 mounted on the frame 2, a first slide cylinder 432 mounted on the first support frame 431 along the X-axis direction, a first connecting frame 433 mounted on the output end of the first slide cylinder 432, a first linear bearing 434 mounted vertically on the first connecting frame 433, a first receiving cylinder 435 sleeved on the first linear bearing 434, and a first cylinder A436 mounted vertically on the first connecting frame 433 for driving the first receiving cylinder 435 to rise and fall. The first connecting frame 433 is provided with a first slot for receiving materials, and the first slot corresponds vertically to the first receiving cylinder 435.

[0039] It should be noted that the lower end of the oil separator pipe 200 extends into the first receiving cylinder 435, and the upper end of the oil separator pipe 200 is located on the upper surface of the first receiving cylinder 435. Because its diameter is larger than the diameter of the hole in the first receiving cylinder 435, it will not fall down.

[0040] In actual use, the first slide cylinder 432 drives the first connecting frame 433 to align the first slot with the discharge port of the first vibrator 42. After the oil separator pipe 200 enters the slot along the first vibrator 42, the first slide cylinder 432 drives the first connecting frame 433 to move, so that the slot is misaligned with the first vibrator 42 to block the discharge port of the first vibrator 42. Then, the first cylinder A436 drives the first receiving cylinder 435 to rise and lift the oil separator pipe 200 from the slot. Then, the first transfer component 45 transfers the lifted oil separator pipe 200.

[0041] In the above design, the structural design and specific implementation of the No. 1 distributor 43 can realize the distribution of oil to the oil pipe 200. By lifting the oil pipe 200 with the No. 1 receiving cylinder 435, it is easy to transfer the No. 1 transfer component 45.

[0042] Specifically: such as Figure 2 As shown, the first transfer assembly 45 includes a first support 451 mounted on the frame 2, a first linear module A452 mounted on the first support 451 along the Y-axis, a first linear module B453 mounted at the output end of the first linear module A452 along the Z-axis, a connecting plate 455 mounted at the output end of the first linear module B453, and a first gripper 454 mounted on the connecting plate 455.

[0043] In actual use, the first linear module A452 drives the first linear module B453 to move along the Y-axis so that the first gripper 454 corresponds to the oil distribution pipe 200 in the first distributor 43. The first linear module B453 drives the connecting plate 455 to move the first gripper 454 up and down, and the first gripper 454 clamps the oil distribution pipe 200 in the first distributor 43. Then, the first linear module A452 drives the first linear module B453 to move along the Y-axis to above the end cover. After the first linear module B453 drives the first gripper 454 to descend into place, the first gripper 454 disengages from the clamped oil distribution pipe 200.

[0044] In the above design, the structural design and specific implementation of the No. 1 transfer component 45 can realize the stable transfer of the oil separator 200 between the No. 1 distributor 43 and the end cap.

[0045] Specifically: such as Figure 1 and Figure 4 As shown, the oil distribution pipe and end cap assembly mechanism 5 includes a second support 51 mounted on the frame 2, a second tooling 52 mounted on the second support 51, a second lifting frame 53 mounted on the second support 51, a pressure head 54 mounted on the second lifting frame 53, and a second electric cylinder 55 mounted on the second support 51 for driving the second lifting frame 53 to rise and fall. Figure 8As shown, the second tooling 52 includes a second pallet 521 mounted on a second support 51, a vertical plate 522 mounted on the second pallet 521, a second linear guide rail 523 mounted on the vertical plate 522, a second positioning plate 524 slidably mounted on the second linear guide rail 523, elastic members 525 whose two ends respectively abut against the lower end face of the second positioning plate 524 and the upper end face of the second pallet 521, and a plurality of second rotary clamping cylinders 526 mounted on the second positioning plate 524. The second positioning plate 524 positions the end cap using its own positioning pins.

[0046] In actual use, first open the second rotary clamping cylinder 526. Then, the transfer assembly places the end cap on the second positioning plate 524 for positioning. The second rotary clamping cylinder 526 clamps the end cap on the positioning plate. When the oil distribution pipe 200 is assembled with the end cap, the second electric cylinder 55 drives the second lifting frame 53 to move down, so that the second lifting frame 53 drives the pressure head 54 to press down on the oil distribution pipe 200. During the process of the oil distribution pipe 200 being pressed down by the pressure head 54, the elastic element 525 is compressed until the oil distribution pipe 200 is assembled with the end cap. Then, the second lifting frame 53, driven by the second electric cylinder 55, drives the pressure head 54 to disengage from the oil distribution pipe 200. After that, the elastic element 525 returns to its original position.

[0047] In the above design, the structural design and specific implementation of the oil separator and end cap assembly mechanism 5 can realize the assembly of the oil separator 200 and the end cap, and during the assembly process, the elastic element 525 is used to buffer the pressure head 54 on the oil separator 200 to prevent the oil separator 200 from being damaged by excessive impact force.

[0048] Specifically: such as Figure 1 , Figure 5 and Figure 6As shown, the pressure relief valve feeding assembly mechanism 6 includes a No. 4 vibratory plate 61 mounted on the frame 2, a No. 4 linear vibrator 62 connected to the No. 4 vibratory plate 61, a No. 4 distributor 63 connected to the No. 4 linear vibrator 62, a No. 4 oil injection assembly 64 mounted on the No. 4 distributor 63, a No. 4 transfer assembly assembly 65 mounted on the frame 2, and a No. 4 tooling 66. The No. 4 distributor 63 includes a No. 4 support frame 631 mounted on the frame 2, a No. 4 receiving block 632 mounted on the No. 4 support frame 631, a No. 4 linear bearing mounted on the No. 4 support frame 631, a No. 4 receiving cylinder 634 sleeved on the No. 4 linear bearing, and a No. 4 cylinder 633 mounted on the No. 4 support frame 631 for driving the No. 4 receiving cylinder 634 to rise and fall. The No. 4 receiving block 632 is provided with a No. 4 receiving groove connected to the No. 4 linear vibrator 62. The fourth vertical hole is connected to the fourth receiving groove. The fourth receiving cylinder 634 is slidably connected to the fourth receiving groove. The fourth oil spraying assembly 64 is mounted on the fourth support frame 631. The fourth transfer assembly 65 includes a fourth support 651 mounted on the frame 2, a fourth linear module A652 mounted on the fourth support 651 along the Y-axis, a fourth linear module B658 mounted at the output end of the fourth linear module A652, a fourth frame 653 mounted at the output end of the fourth linear module B658, a fourth rotating shaft 654 rotatably mounted on the fourth frame 653, a fourth motor 655 mounted on the fourth frame 653 for driving the fourth rotating shaft 654 to rotate, a sleeve 656 mounted at the lower end of the fourth rotating shaft 654 and having a groove with the slot facing downwards, and an elastic plunger 657 radially mounted in the sleeve 656.

[0049] It should be noted that the fourth fuel injection assembly 64 has the same structure as the first fuel injection assembly 44. The elastic plunger 657 is a ball-head elastic plunger 657. The pressure relief valve 300 has threads on its outer wall.

[0050] In actual use, the pressure relief valve 300 is vibrated to the fourth vibrator 62 via the fourth vibrating plate 61. The fourth vibrator 62 then vibrates the pressure relief valve 300 to the fourth distributor 63. Subsequently, the pressure relief valve 300 in the fourth distributor 63 is transferred to the fourth oil spraying assembly 64 via the fourth transfer assembly 65 for oil spraying. After oil spraying, the pressure relief valve 300 is clamped and assembled with the end cap on the fourth tooling 66. After receiving the pressure relief valve 300 from the fourth vibrator 62, the fourth receiving cylinder 634 of the fourth distributor 63 is driven by the fourth cylinder 633 to rise, lifting the pressure relief valve 300. At the same time, the rising of the fourth receiving cylinder 634 prevents the fourth vibrator 62 from continuing to feed, thus achieving material distribution. The fourth transfer assembly component 65, driven by the fourth linear module A652, moves the fourth linear module B658 to allow the upper end of the pressure relief valve 300 located in the fourth feeder 63 to penetrate into the groove and abut against the elastic plunger 657, compressing the elastic plunger 657. Then, the fourth linear module B658 drives the fourth frame 653 to move the fourth rotating shaft 654 upward. Due to the extrusion force exerted by the elastic plunger 657 on the outer wall of the pressure relief valve 300, the pressure relief valve 300 is clamped. Then, the fourth linear module A652 drives the fourth linear module B658 to move to the corresponding position of the end cap on the fourth tooling 66. Subsequently, the fourth linear module B658 drives the fourth frame 653 downward, and the fourth motor 655 drives the fourth rotating shaft 654 to rotate, connecting the pressure relief valve 300 to the threaded hole on the end cap.

[0051] In the above design, the structural design and specific implementation of the pressure relief valve feeding and assembly mechanism 6 can effectively realize the feeding and assembly of the pressure relief valve 300. By spraying oil on the outer wall of the pressure relief valve 300, the friction between the pressure relief valve 300 and the end cover during assembly can be reduced.

[0052] Specifically: such as Figure 5 As shown, the fourth tooling 66 includes a fourth pallet 661 mounted on the frame 2, a fourth positioning plate 662 mounted vertically on the fourth pallet 661, and several fourth rotary clamping cylinders 663 mounted on the fourth positioning plate 662.

[0053] In actual use, the No. 4 rotary clamping cylinder 663 is opened first, and then the semi-finished product is transferred to the No. 4 positioning plate 662 for positioning through the transfer mechanism 3. Then the end cap is clamped by the No. 4 rotary clamping cylinder 663.

[0054] In the above design, the structural design of tooling 66 No. 4 can effectively fix the end cover. After the end cover is fixed, the end cover remains stationary, which can ensure the stability of the pressure relief valve 300 during the threaded connection with the end cover.

[0055] Specifically: such as Figure 7As shown, the transfer mechanism 3 includes a base 31, a robotic arm 32 mounted on the base 31, a flange mounting bracket 33 for an end effector mounted on the robotic arm 32, and a first cylinder gripper 34 and a second cylinder gripper 35 mounted on the flange mounting bracket 33.

[0056] In actual use, it is installed on the ground via the base 31, and the flange mounting bracket 33 is driven by the robotic arm 32 to move the first cylinder gripper 34 and the second cylinder gripper 35. The first cylinder gripper 34 or the second cylinder gripper 35 is selected according to the model of the end cover.
