Compared with the prior art, when installing oil seals, it is only necessary to manually place the end cap on the feeding table, then start the central control button, and the end cap is transferred to the placement plate of the turntable through the end cap transfer mechanism. At the same time, the oil seal is placed on the storage mechanism. The storage mechanism rotates until the oil seal falls onto the conveyor. The conveyor transfers the oil seal to the position directly below the pressure rod. Then the pressure rod starts to press down and press the oil seal into the end cap. In this way, in the entire process of pressing the oil seal, it is only necessary to manually place the end cap on the feeding table and the oil seal on the storage mechanism in sequence, and the equipment can realize the automatic pressing.

[0015] 2. The present invention provides an automatic oil sealing machine for end caps. The conveying component includes a conveying plate with a receiving groove. When the oil seal on the storage mechanism falls into the receiving groove of the conveying plate, the oil seal in the receiving groove is conveyed by the conveying plate to the position directly below the pressure plate. Then, the pressure rod presses vertically downward to pick up the oil seal on the conveying plate and move it above the pressure rod. At this time, the conveying plate is in the second position. After the oil seal is removed, the conveying plate retracts and moves to the first position, waiting for the oil seal to continue falling into the receiving groove. After the conveying plate is removed, the pressure rod falls again to press the oil seal into the end cap.

[0016] 3. The present invention provides an automatic end cap oil sealing machine. The storage mechanism includes a storage base plate and a storage turntable disposed above the storage base plate. The storage turntable has multiple storage stations, each storage station having a groove. The storage base plate has a conveying groove. When any groove aligns with the conveying groove, the oil seal in the groove will fall into the receiving groove through the conveying groove, and then be conveyed to the position directly below the pressure rod for operation through the receiving groove.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Example

[0033] This embodiment provides an automatic end cap oil sealing machine, including: a housing 1; a feeding platform 2, disposed above the housing 1, for placing end caps 21; a turntable 3, rotatably mounted on the housing 1, with multiple placement trays 31 for placing end caps 21 disposed above the turntable 3; an end cap conveying mechanism 4, disposed between the feeding platform 2 and the turntable 3, for conveying the end caps 21 on the feeding platform 2 to the placement trays 31; and an oil seal conveying mechanism 5, including a storage mechanism 51 for storing oil seals, a conveying component 52 for conveying oil seals to the top of the housing 1, and a pressing rod 53 for pressing the oil seals into the end caps 21.

[0034] The specific improvements mentioned above are as follows: Figure 1 and Figure 2As shown, compared to existing technologies, when installing oil seals, only manual placement of the end cap 21 on the feeding table 2 is required, filling the entire feeding table 2. Then, the central control button is activated. The feeding table 2 is equipped with a sensor. When the sensor detects the presence of the end cap 21, the end cap 21 is clamped by the end cap transmission mechanism 4 and transferred to the placement plate 31 of the turntable 3. At the same time, the oil seal is placed on the storage mechanism 51. The storage mechanism 51 rotates, and there is a channel between the storage mechanism 51 and the conveyor 52. When the storage mechanism rotates to the channel, the oil seal will fall into the conveyor 52 along the channel. The conveyor 52 then transfers the oil seal to the position directly below the pressure rod 53. The pressure rod 53 then presses downward to press the oil seal into the end cap 21. Thus, in the entire process of pressing the oil seal, only manual placement of the end cap 21 on the feeding table 2 and the oil seal on the storage mechanism 51 are required, and the equipment can achieve automated pressing, greatly improving production efficiency.

[0035] Based on the above embodiments: the conveying member 52 includes a conveying plate 521 disposed below the storage mechanism 51. The conveying plate 521 is provided with a receiving groove 522 for the oil seal in the storage mechanism 51 to fall into. The pressure rod 53 can be inserted into the receiving groove 522 to pick up the material. The conveying plate 521 has a first position for the oil seal to fall into the receiving groove 522 and a second position for the receiving groove 522 to be vertically aligned with the pressure rod 53. The conveying plate 521 can slide back and forth between the first position and the second position.

[0036] The specific improvements mentioned above are as follows: The conveying component 52 includes a conveying plate 521, and the conveying plate 521 is provided with a receiving groove 522. When the oil seal on the storage mechanism 51 falls into the receiving groove 522 of the conveying plate 521, the oil seal located in the receiving groove 522 is transported by the conveying plate 521 to the position directly below the pressure plate. Then the pressure rod 53 presses vertically downward, taking the oil seal on the conveying plate 521 above the pressure rod 53. At this time, the conveying plate 521 is in the second position. After the oil seal is taken away, the conveying plate 521 retracts and moves to the first position, waiting for the oil seal to continue falling into the receiving groove 522. After the conveying plate 521 is removed, the pressure rod 53 falls again, pressing the oil seal into the end cover 21.

[0037] Based on the above embodiments: the storage mechanism 51 includes a storage base plate 511 and a storage turntable 512 coaxially disposed above the storage base plate 511. The storage base plate 511 is provided with a conveying groove 513 located above the receiving groove 522. The storage turntable 512 is provided with a plurality of storage stations 54 arranged along the circumference of the storage turntable 512. The storage station 54 includes a groove 541 for embedding an oil seal and a plurality of first limiting rods 25 disposed on the outer periphery of the groove 541 for positioning the outer side of the oil seal. The first limiting rods 25 are fitted with pressure blocks 543 for pressing the oil seal. When any groove 541 rotates to a position above the conveying groove 513, the oil seal falls into the receiving groove 522.

[0038] The specific improvements mentioned above are as follows: Figures 2-5 As shown, the storage mechanism 51 includes a storage base plate 511 and a storage turntable 512 disposed above the storage base plate 511. A motor driving the storage turntable 512 is connected below it. Below the storage base plate 511 is a conveying groove 513 corresponding to the receiving groove 522. The conveying groove 513 is only large enough for one oil seal to fall into. The storage turntable 512 has multiple storage stations 54 for storing oil seals. Each storage station 54 has a groove 541. To restrict the movement direction of the oil seal, three first limiting rods 25 are provided around the outer periphery of the groove 541. A pressure block 543 is provided above the oil seal to press it down and ensure that pressure is provided during rotation to cause the oil seal in the groove 541 to fall into the conveying groove 513. When any oil seal in any groove 541 falls into the conveying groove 513... The oil seal continues to fall down along the direction of the conveyor 513 until it falls into the receiving groove 522. There is a sensor on the storage turntable 512, which is connected to a receiver on the conveyor plate 521. When the storage turntable 512 rotates, the sensor transmits information to the receiver on the conveyor plate 521. The conveyor rod starts to move, sending the oil seal in the receiving groove 522 directly below the pressure rod 53. There is also a receiver on the pressure rod 53. After the conveyor rod moves, the receiver receives information and drives the pressure rod 53 to move downward and insert into the receiving groove 522. The oil seal is removed by the friction between the oil seal and the pressure rod 53. There is also a sensor above the pressure rod 53. When the sensor senses that the pressure rod 53 is moving upward, it transmits information to the transmission plate. The transmission rod retracts, and the pressure rod 53 moves downward again, pressing the oil seal into the end cover 21.

[0039] Based on the above embodiments: the feeding table 2 includes a feeding turntable 22 and a placement station 23 circumferentially arranged above the feeding turntable 22. The placement station 23 includes a receiving base 24 for receiving end caps 21 and at least two second limiting rods 542 arranged on the outer periphery of the receiving base 24. Multiple end caps 21 can be stacked vertically above the receiving base 24.

[0040] The specific improvements mentioned above are as follows: Figures 3-6 As shown, the function of the feeding platform 2 is to send the end cap 21 to the turntable 3. The motor under the feeding turntable 22 will drive the corresponding receiving base 24 to move up one position after the end cap 21 on any of the placement stations 23 is removed, so that the sensor on the feeding platform 2 can continue to sense the end cap 21. In order to enable the end cap 21 to be stacked upward, three second limit rods 542 are set on the outer periphery of the receiving base 24.

[0041] Based on the above embodiments: the end cap transmission mechanism 4 includes a first gripper cylinder 41 and a moving cylinder 42 that drives the first gripper cylinder 41 to move. The moving cylinder 42 is provided with a moving shaft 43. The first gripper cylinder 41 can reciprocate along the setting direction of the moving shaft 43. The first gripper cylinder 41 has an initial position above the receiving chassis 24 and a placement position above the placement plate 31. The moving cylinder 42 can drive the first gripper cylinder 41 to reciprocate between the initial position and the placement position.

[0042] The specific improvements mentioned above are as follows: Figure 4 As shown, the end cap transfer mechanism 4 includes a first gripper cylinder 41 and a moving cylinder 42 that drives the first gripper cylinder 41 to move. When the sensor on the feeding table 2 senses the presence of the end cap 21, the first gripper cylinder 41 starts, moves downward, opens its gripper to clamp the end cap 21, and then moves upward. The moving cylinder 42 then drives the first gripper cylinder 41 to move along the setting direction of the moving shaft 43 to above the placement plate 31 on the turntable 3. Then the first gripper cylinder 41 moves downward, the gripper opens, and the end cap 21 is placed on the placement plate 31. After that, the first gripper cylinder 41 continues to move upward, the gripper tightens, and the moving cylinder 42 drives the first gripper cylinder 41 to return to its original position.

[0043] Based on the above embodiments: a rotary motor 32 for driving the rotary table 3 to rotate is provided below the rotary table 3. The rotary table 3 is provided with a working station 33 located below the pressure rod 53 and several waiting stations 34 waiting to enter the working station 33. An anti-detachment block 35 is provided between the working station 33 and the pressure rod 53 to prevent the end cover 21 from being pulled upward after the pressure rod 53 seals the oil seal into the end cover 21. The anti-detachment block 35 has a first through hole 350 in the middle for the oil seal to pass through.

[0044] The specific improvements mentioned above are as follows: Figure 4 As shown, a rotary motor 32 is installed below the turntable 3 to drive the turntable 3 to rotate. The turntable 3 has a working station 33 and multiple waiting stations 34 waiting to enter the working station 33. When the first gripper cylinder 41 transfers the end cover 21 from the feeding table 2 to the waiting station 34, the rotary motor 32 below the turntable 3 will drive the turntable 3 to rotate, so that the end cover 21 on the waiting station 34 rotates to the working station 33, and then waits for the oil seal to be pressed in.

[0045] Based on the above embodiments: a first oil injection block 36 for injecting lubricating oil into the oil seal is provided above the anti-detachment block 35. The first oil injection block 36 is provided with a first oil injection port 37. A second oil injection block 361 is provided on the pressure rod 53. A second oil injection port 362 communicating with the second oil injection block 361 is provided on the pressure rod 53. The first oil injection block 36 is provided with a second through hole 351 for the oil seal to pass through, and a plurality of first oil injection holes 352 distributed circumferentially on the inner wall of the second through hole 351. The plurality of first oil injection holes 352 are connected to the first oil injection port 37. The side of the pressure rod 53 facing the anti-detachment block 35 is provided with a second oil injection hole 353 communicating with the second oil injection block 361.

[0046] The specific improvements mentioned above are as follows: Figure 7 and Figure 8 As shown, when the pressure rod 53 is pressed into the anti-detachment block 35 and the first oil injection block 36, the oil seal will stick to the inner wall of the first oil injection block 36. At this time, the first oil injection port 37 and the second oil injection port 362 simultaneously spray oil to lubricate the inner and outer walls of the oil seal. After lubrication is completed, the pressure rod 53 continues to press downward into the end cover 21.

[0047] Based on the above embodiments: the chassis 1 is also provided with a material picking mechanism 6 that is linked with the turntable 3, the turntable 3 is also provided with a material picking station 61, the material picking mechanism 6 includes a moving motor 62 and a second gripper cylinder 63 provided on the moving motor 62, the side of the material picking mechanism 6 is provided with a receiving platform 64 for placing the processed end cap 21, the second gripper cylinder 63 has a gripping position above the material picking station 61 and a receiving position above the receiving platform 64.

[0048] The specific improvements mentioned above are as follows: Figure 4 and Figure 6 As shown, there is a material picking station 61 on the turntable 3. After the oil seal is pressed into the end cover 21, the rotating motor 32 will drive the turntable 3 to rotate, which will bring the end cover 21 on the working station 33 to the material picking station 61. Then the second gripper cylinder 63 will move downward and open the gripper to clamp the end cover 21. Then the moving rod of the moving motor 62 will move from the gripping position to the receiving position.

[0049] Based on the above embodiments: the chassis 1 is also provided with a receiving device 7, the receiving device 7 includes a receiving base 71 that rotates in a circle and a plurality of receiving stations 72 provided above the base. The receiving station 72 includes a placement tray 73 for accommodating end caps 21 and at least two third limiting rods 74 provided on the outer periphery of the placement tray 73. A plurality of end caps 21 can be stacked vertically above the placement tray 73.

[0050] The specific improvements mentioned above are as follows: Figure 4 As shown, the receiving device 7 includes a receiving base 71 and multiple receiving stations 72 arranged on the receiving base 71 and along the circumference of the receiving base 71. When the second gripper cylinder 63 moves from the gripping position to the receiving position, the second gripper cylinder 63 moves downward to the position directly above the placement plate 73, and then releases the gripper. The end cap 21 will then fall to the placement plate 73 along with the third limit rod 74.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
