[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The turntable layout greatly saves floor space, so that assembly lines with the same production capacity can be realized in a smaller space; and all assembly processes are concentrated on the side of the turntable, with the loading end and the unloading end adjacent to each other, so that fewer or even one staff member can easily manage the entire assembly process, including material supply, process monitoring and finished product offline, thereby significantly reducing manpower requirements, reducing labor costs, and improving production efficiency.

[0014] 2. The empty tray transfer mechanism is set as the first section conveyor belt and the second section conveyor belt with an angle, so that the empty tray transfer mechanism is more suitable for the turntable production line, and the loading end and unloading end of the empty tray transfer mechanism correspond to the loading end and unloading end of the turntable respectively, so as to realize efficient loading and unloading transportation.

[0015] 3. The conventional clamp used to grasp the zinc sleeve generally adopts a tapered rod to penetrate into the zinc sleeve, and grasping is achieved by the interference fit between the tapered rod and the inner wall of the zinc sleeve. In this way, the zinc sleeve is easy to fall off and is also easy to cause deformation and damage of the zinc sleeve, and cause damage to the fixture. The present invention adopts a guide rod to penetrate into the zinc sleeve, and the guide rod only plays a guiding and positioning role. The gripping is performed by the suction of the straw, so that the zinc sleeve can be grasped stably and not easily damaged, the installation is accurate, and the safety of the fixture is guaranteed.

[0016] 4. Conventional clamps for grasping cotton stalks generally grasp the heads of the cotton stalks. Since the cotton stalks are relatively soft and long and not necessarily straight, the bottoms of the cotton stalks are easily misaligned during installation, causing the cotton stalks to be squeezed into the oil tank, resulting in a high defective rate. The present invention grasps the cotton stalks through a cotton stalk suction tube and designs the length of the suction channel so that the cotton stalks can be completely sucked into the suction tube. The cotton stalk suction tube is aligned to the desired position for installation, which can avoid damage to the cotton stalks due to misalignment of the bottoms of the cotton stalks. At the same time, slightly deformed cotton stalks can be corrected, reducing material loss and greatly improving the assembly yield.

[0017] 5. The conventional clamping claws for grabbing the cotton sheet release the cotton sheet after the cotton sheet is aligned to the position. The cotton sheet is easily turned over due to static electricity during the falling process, resulting in a high defective rate. The present invention provides a cotton sheet suction pipe that can move up and down. After the cotton sheet is aligned to the installation position, the cotton sheet suction pipe extends downward all the way to push the cotton sheet to the installation position and then releases the cotton sheet, thereby avoiding the cotton sheet from turning over and greatly improving the assembly yield rate.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are intended to distinguish two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, other steps or units inherent to a process, method, system, product or device that includes a series of steps or units.

[0024] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0025] A lighter automatic cotton loading machine, such as Figures 1 to 5 As shown, it includes a frame 1000, on which a turntable mechanism 100 is arranged, and on the turntable mechanism 100, a plurality of tooling assemblies 700 for fixing the oil tank are arranged at intervals along its circumference, and a loading clamp 800, a zinc sleeve mounting mechanism 200, a cotton rod mounting mechanism 300, a cotton sheet mounting mechanism 400, an air nozzle mounting mechanism 500 and a unloading clamp 1600 are arranged in sequence on the frame 1000 and along the rotation direction of the turntable mechanism 100, and an empty tray transfer mechanism 600 for transporting the tray 2000 is arranged on the frame 1000.

[0026] The loading clamp 800 grabs the oil tank from the tray 2000 of the empty tray transfer mechanism 600 into the tooling assembly 700. There are several rows of oil tanks neatly arranged on the tray 2000, and the loading clamp 800 grabs multiple oil tanks at one time. The turntable mechanism 100 drives the tooling assembly 700 to rotate sequentially into the zinc sleeve installation mechanism 200, the cotton rod installation mechanism 300, the cotton sheet installation mechanism 400, and the air nozzle installation mechanism 500, so that the zinc sleeve, cotton rod, cotton sheet and air nozzle are sequentially installed into the oil tank on the tooling assembly 700, and the unloading clamp 1600 then grabs the assembled oil tank back into the tray 2000 of the empty tray transfer mechanism 600 to complete the unloading.

[0027] The turntable mechanism 100 includes a rotating disk 101 and a mounting disk 102 movably arranged above the rotating disk 101. The mounting disk 102 is coaxially arranged with the rotating disk 101. The tooling assembly 700 is fixed on the rotating disk 101. Several tooling assemblies 700 are fixed at equal intervals at the edge of the rotating disk 101. The rotating disk 101 drives the tooling assembly 700 to rotate, so that the tooling assembly 700 enters each process in sequence.

[0028] The mounting plate 102 moves in the vertical direction. A plurality of guide rails 103 are provided on the mounting plate 102. A mounting frame 104 is slidably connected to the guide rails 103. The guide rails 103 are provided along the diameter direction of the rotating plate 101. When the mounting plate 102 moves in the vertical direction, the mounting frame 104 slides forward and backward along the guide rails 103. Therefore, the mounting frame 104 can move in the vertical direction and the horizontal forward and backward direction.

[0029] A driving disk 105 rotates above the mounting disk 102, and a driving rod 106 is respectively connected between the driving disk 105 and the mounting frame 104. One end of the driving rod 106 is hinged to the driving disk 105, and the other end is hinged to the mounting frame 104. The driving disk 105 rotates back and forth, thereby driving the mounting frame 104 to move forward and backward on the guide rail 103 through the driving rod 106, and all the mounting frames 104 move synchronously.

[0030] The turntable mechanism 100 of this embodiment is prior art and was purchased from Yishunxin (Suzhou) Automation Equipment Co., Ltd. The specific structural principle can refer to the patent "CN216326870U, a standard platform for turntable automation equipment".

[0031] The first ferry plate 900 and the second ferry plate 1700 are rotatably connected to the frame 100, and the first carrying jaw 1800 and the second carrying jaw 1900 are provided on the turntable mechanism 100. The first carrying jaw 1800 and the second carrying jaw 1900 are respectively connected to the mounting frame 104, so that the first carrying jaw 1800 and the second carrying jaw 1900 can move up and down and forward and backward, and the first carrying jaw 1800 and the second carrying jaw 1900 are adjacent to the mounting frame 104 where they are located.

[0032] The loading clamp 800 grabs the oil tank from the material tray 2000 of the empty tray transfer mechanism 600 and puts it into the first ferry tray 900, and the first transport clamp 1800 grabs the oil tank from the first ferry tray 900 and puts it into the tooling assembly 700, thereby completing the loading of the oil tank; the second transport clamp 1900 grabs the assembled oil tank into the second ferry tray 1700, and the unloading clamp 1600 grabs the assembled oil tank from the second ferry tray 1700 back into the empty material tray 2000 of the empty tray transfer mechanism 600, thereby completing the unloading of the oil tank.

[0033] The moving direction of the loading jaw 800 is parallel to the moving direction of the first transporting jaw 1800, and the first ferry plate 900 is located between the loading jaw 800 and the first transporting jaw 1800; the moving direction of the unloading jaw 1600 is parallel to the moving direction of the second transporting jaw 1900, and the second ferry plate 1700 is located between the unloading jaw 1600 and the second transporting jaw 1900. The loading jaw 800 has the same structure as the unloading jaw 1600, the first transporting jaw 1800 has the same structure as the second transporting jaw 1900, and the first ferry plate 900 has the same structure as the second ferry plate 1700. The first transporting jaw 1800 and the second transporting jaw 1900 use the jaws driven by cylinders in the prior art.

[0034] The first ferry plate 900 is provided with four rows of sockets 901 for inserting oil tanks, and the four rows of sockets 901 are arranged in a rectangular shape. Ten oil tanks can be inserted in each socket 901, and the loading clamp 800 can clamp 10 oil tanks at the same time and insert them into the socket 901. The first transport clamp 1800 and the tooling assembly 700 can fix five oil tanks at the same time. The first ferry plate 900 is driven by the ferry cylinder 902 to move in the left and right directions. After the first transport clamp 1800 clamps the five oil tanks in the socket 901, the first ferry plate 900 moves to the left to align the remaining five oil tanks in the socket 901 with the first transport clamp 1800. After all the ten oil tanks in the socket 901 are grabbed, the first ferry plate 900 rotates 90° to align the new socket 901 with the first transport clamp 1800, and the loading clamp 800 replenishes the oil tank into the empty socket 901, and the loading is repeated continuously.

[0035] When unloading, the second transport clamp 1900 clamps the assembled oil tank from the tooling assembly 700 and inserts it into the socket 901 above the second ferry plate 1700. After the socket 901 is filled with 10 oil tanks, the second ferry plate 1700 rotates 90°, and the unloading clamp 1600 grabs the 10 oil tanks in the socket 901 at a time, and the unloading cycle is repeated continuously.

[0036] like Figure 6 and Figure 7 As shown, the empty tray transfer mechanism 600 includes a first conveyor belt 601 and a second conveyor belt 602 with an angle, the conveying direction of the first conveyor belt 601 is perpendicular to the moving direction of the first transport clamp 1800, and the conveying direction of the second conveyor belt 602 is perpendicular to the moving direction of the second transport clamp 1900. This makes the empty tray transfer mechanism 600 more compatible with the production line with a turntable layout, the loading clamp 800 can directly grab the oil tanks from the tray 2000 in a row, and the unloading clamp 1600 can also directly put the oil tanks into the tray 2000 in a row.

[0037] The empty tray transfer mechanism 600 is provided with a steering assembly for driving the material tray 2000 to turn, and the steering assembly includes a swing rod 603 hinged at the bottom of the first section of the conveyor belt 601 of the empty tray transfer mechanism 600, and the movable end of the swing rod 603 is rotatably connected to a guide wheel 604 for fitting with the side wall of the material tray 2000. The movable end of the swing rod 603 rotates from the first section of the conveyor belt 601 to the second section of the conveyor belt 602, thereby causing the material tray 2000 to turn from the first section of the conveyor belt 601 to the second section of the conveyor belt 602.

[0038] A guide channel 605 is provided on the empty tray transfer mechanism 600. The guide channel 605 is located at the connection between the first section conveyor belt 601 and the second section conveyor belt 602, extending from the first section conveyor belt 601 to the second section conveyor belt 602, and the guide wheel 604 protrudes from the guide channel 605 to the surface of the empty tray transfer mechanism 600. When the tray 2000 moves to the guide channel 605, the side wall of the tray 2000 fits with the guide wheel 604, and the side wall of the tray 2000 is parallel to the first section conveyor belt 601. The guide wheel 604 moves along the guide channel 605, so that the tray 2000 turns to the second section conveyor belt 602, and the side wall of the tray 2000 is parallel to the second section conveyor belt 602 to complete the turning.

[0039] The steering assembly also includes a steering cylinder 606 hinged at the bottom of the second section conveyor belt 602 of the empty plate transfer mechanism 600. The piston rod of the steering cylinder 606 is hinged to the swing rod 603. The swing rod 603 is driven to swing along the guide channel 605 through the extension and retraction of the piston rod of the steering cylinder 606.

[0040] like Figures 7 to 9 As shown, the zinc sleeve installation mechanism 200 includes a zinc sleeve loading platform 202, a zinc sleeve vibrating loading tray 201 and a zinc sleeve vacuum adsorption device 203. The zinc sleeve vibrating loading tray 201 transports the zinc sleeve to the zinc sleeve loading platform 202, and the zinc sleeve vacuum adsorption device 203 then grabs the zinc sleeve and loads it into the oil tank on the tooling assembly 700.

[0041] A zinc sleeve loading plate 2021 is slidably connected to the zinc sleeve loading platform 202. The zinc sleeve loading plate 2021 is driven by a cylinder and is parallel to the moving direction of the mounting frame 104. The discharge port of the zinc sleeve vibration loading tray 201 is in contact with the upper end surface of the zinc sleeve loading plate 2021 or has a slight gap, so that the zinc sleeve at the end of the discharge port is in contact with the upper end surface of the zinc sleeve loading plate 2021. A zinc sleeve accommodating groove 2022 is provided on the upper end surface of the zinc sleeve loading plate 2021.

[0042] When the zinc sleeve loading plate 2021 moves to the zinc sleeve receiving groove 2022 and is aligned with the discharge port of the zinc sleeve vibrating loading tray 201, the last row of zinc sleeves will fall into the zinc sleeve receiving groove 2022, and then the zinc sleeve loading plate 2021 moves in the direction of the zinc sleeve vacuum adsorption device 203, and the zinc sleeve vacuum adsorption device 203 grabs the zinc sleeve in the zinc sleeve receiving groove 2022 and loads it into the oil tank on the tooling assembly 700. Then the zinc sleeve loading plate 2021 continues to move in the direction of the zinc sleeve vibrating loading tray 201, so that the next zinc sleeve falls into the zinc sleeve receiving groove 2022, and the cycle repeats. In this embodiment, 5 zinc sleeve receiving grooves 2022 are provided on the zinc sleeve loading plate 2021, and the zinc sleeve vibrating loading tray 201 is connected to 5 discharge pipes corresponding thereto, so that 5 zinc sleeves can be loaded at the same time, and the 5 oil tanks in the tooling assembly 700 are installed at the same time.

[0043] The zinc sleeve vacuum adsorption device 203 includes a zinc sleeve bracket 2031 connected to the mounting frame 104, so the zinc sleeve vacuum adsorption device 203 can be driven to move up and down and forward and backward through the turntable mechanism 100. A zinc sleeve suction pipe 2032 is vertically arranged at the bottom of the zinc sleeve bracket 2031, and the zinc sleeve suction pipe 2032 is vacuum adsorbed. A zinc sleeve guide rod 2033 is arranged in the middle of the suction channel of the zinc sleeve suction pipe 2032, and the zinc sleeve guide rod 2033 passes through the bottom opening of the zinc sleeve suction pipe 2032 and extends downward.

[0044] The zinc sleeve guide rod 2033 is cylindrical and is coaxially arranged with the air suction channel of the zinc sleeve suction pipe 2032. The diameter of the zinc sleeve guide rod 2033 is smaller than the air suction channel, and there is a gap between the peripheral side wall of the zinc sleeve guide rod 2033 and the air suction channel. The zinc sleeve vacuum adsorption device 203 inserts the zinc sleeve guide rod 2033 into the zinc sleeve, and the zinc sleeve guide rod 2033 fits with the inner wall of the zinc sleeve or has a small gap, and the zinc sleeve is sucked into the opening along the zinc sleeve guide rod 2033 by the zinc sleeve suction pipe 2032.

[0045] The zinc sleeve guide rod 2033 includes an upper end and a lower section. The diameter of the upper section is larger than the diameter of the lower section, so that a step is formed in the opening of the air intake channel. After the zinc sleeve is sucked into the opening of the air intake channel, it will abut against the step and will not continue to move inward. When installing the zinc sleeve, the zinc sleeve vacuum adsorption device 203 extends the zinc sleeve suction pipe 2032 into the oil tank. After the zinc sleeve suction pipe 2032 closes the suction force, the zinc sleeve will slide down along the guide rod to complete the installation. Through the guidance restriction of the guide rod, the installation accuracy is high. Five zinc sleeve suction pipes 2032 are arranged at the bottom of the zinc sleeve bracket 2031 of this embodiment, and five oil tanks on the tooling assembly 700 can be installed at the same time.

[0046] like Figures 11 to 14As shown, the cotton stalk installation mechanism 300 includes a cotton stalk loading platform 302, a cotton stalk vibrating loading tray 301 and a cotton stalk vacuum adsorption device 303. The cotton stalk vibrating loading tray 301 transports the cotton stalks to the cotton stalk loading platform 302, and the cotton stalk vacuum adsorption device 303 then grabs the cotton stalks and loads them into the oil tank on the tooling assembly 700.

[0047] A cotton stalk loading plate 3021 is slidably connected to the cotton stalk loading platform 302, and the cotton stalk loading plate 3021 is driven by a cylinder to move left and right, and is perpendicular to the moving direction of the mounting frame 104. The cotton stalk loading plate 3021 fits with the discharge channel of the cotton stalk vibration loading tray 301, so that a cotton stalk at the front end of the discharge channel fits with the cotton stalk loading plate 3021, and the cotton stalk loading plate 3021 is provided with a cotton stalk accommodating groove 3022 toward the discharge channel of the cotton stalk vibration loading tray 301, and the cotton stalk accommodating groove 3022 can accommodate one cotton stalk.

[0048] When the cotton stalk loading plate 3021 moves to the point where the receiving slot is aligned with the discharge channel, the frontmost cotton stalk will move into the cotton stalk receiving slot 3022. When the cotton stalk loading plate 3021 moves back at any time, the receiving slot and the discharge channel are re-displaced, and the cotton stalk vacuum adsorption device 303 grabs the cotton stalk in the cotton stalk receiving slot 3022. Then the cotton stalk loading plate 3021 moves again to the point where the receiving slot is aligned with the discharge channel, so that the next cotton stalk enters the cotton stalk receiving slot 3022, and the feeding cycle is repeated. In this embodiment, there are five cotton stalk receiving slots 3022, and five discharge channels are correspondingly provided. The cotton stalk loading plate 3021 can take out five cotton stalks at the same time when it moves.

[0049] The cotton stalk vacuum adsorption device 303 includes a cotton stalk support 3031 connected to the mounting frame 104, so the cotton stalk vacuum adsorption device 303 can be driven to move up and down and forward and backward through the turntable mechanism 100. A cotton stalk suction pipe 3032 is vertically arranged at the bottom of the cotton stalk support 3031. The cotton stalk suction pipe 3032 adopts vacuum adsorption. The length of the suction channel of the cotton stalk suction pipe 3032 is greater than the length of the cotton stalk, so that the cotton stalk suction pipe 3032 can completely suck the cotton stalk into the suction channel.

[0050] A step is provided in the air suction channel of the cotton stalk suction pipe 3032, and the length of the lower half of the step is greater than or equal to the length of the cotton stalk. After the cotton stalk suction pipe 3032 sucks the cotton stalk, the head of the cotton stalk abuts against the step and does not move upward. When installing the cotton stalk, the cotton stalk vacuum adsorption device 303 extends the cotton stalk suction pipe 3032 into the oil tank, aligns the bottom opening of the cotton stalk suction pipe 3032 with the installation position, and then releases the cotton stalk, so that the cotton stalk is accurately installed in place, the installation is accurate, and the yield rate is high. In this embodiment, 5 cotton stalk suction pipes 3032 are provided at the bottom of the cotton stalk bracket 3031, and 5 oil tanks in the tooling assembly 700 can be installed at the same time.

[0051] like Fig.15 and Fig.16 As shown, the cotton sheet installation mechanism 400 includes a cotton sheet loading platform 402, a cotton sheet vibrating loading tray 401 and a cotton sheet vacuum adsorption device 403. The cotton sheet vibrating loading tray 401 transports the cotton sheets to the cotton sheet loading platform 402, and the cotton sheet vacuum adsorption device 403 then grabs the cotton sheets and loads them into the oil tank on the tooling assembly 700; wherein the structural principle of the cotton sheet loading platform 402 is the same as the structural principle of the cotton stalk loading platform 302, and the same loading method is adopted, which will not be repeated.

[0052] The cotton sheet vacuum adsorption device 403 includes a cotton sheet support 4031 connected to the mounting frame 104, so that the cotton rod vacuum adsorption device 303 can be driven to move up and down and forward and backward through the turntable mechanism 100. A cotton sheet suction pipe 4032 is movably arranged on the cotton sheet support 4031 in the vertical direction. The cotton sheet suction pipe 4032 is fixed to the bottom of the cylinder and is driven to move up and down by the cylinder. The cotton sheet support 4031 is provided with a mounting plate located below the cylinder, and a sleeve 4033 is provided on the mounting plate. The sleeve 4033 is coaxially arranged with the cotton sheet. The cotton sheet suction pipe 4032 penetrates into the sleeve 4033 and slides up and down along the sleeve 4033. The cotton sheet suction pipe 4032 can extend from the bottom opening of the sleeve 4033.

[0053] A limit block 4034 is vertically arranged on the top of the mounting plate to limit the downward movement of the cotton sheet suction tube 4032 and improve the installation accuracy. The limit block 4034 is connected to the mounting plate by a threaded connection, and the height can be adjusted up and down, which can be adjusted according to different assembled oil tank models.

[0054] After the cotton sheet suction tube 4032 absorbs the cotton sheet, it moves upward and retracts into the sleeve 4033. The peripheral side wall of the cotton sheet fits with the sleeve 4033 to prevent the cotton sheet from shifting. When installing the cotton sheet, align the sleeve 4033 with the installation position, then extend the cotton sheet suction tube 4032 downward to the installation position and release the cotton sheet, so as to achieve accurate installation of the cotton sheet and prevent the cotton sheet from turning over, and the yield rate is high. In this embodiment, 5 cotton sheet suction tubes 4032 are arranged at the bottom of the cotton sheet bracket 4031, and 5 oil tanks in the tooling assembly 700 can be installed at the same time.

[0055] like Fig.17 and Fig.18 As shown, the air nozzle installation mechanism 500 includes an air nozzle loading platform 502, an air nozzle vibration loading tray 501 and an air nozzle vacuum adsorption device 503. The air nozzle vibration loading tray 501 transports the air nozzle to the air nozzle loading platform 502, and the air nozzle vacuum adsorption device 503 then grabs the air nozzle and loads it into the oil tank on the tooling assembly 700; wherein the structural principle of the air nozzle loading platform 502 is the same as the structural principle of the zinc sleeve loading platform 202, and the same loading method is adopted, which will not be repeated.

[0056] The air nozzle vacuum adsorption device 503 includes an air nozzle bracket 5031 connected to the mounting frame 104, so the air nozzle vacuum adsorption device 503 can be driven to move up and down and forward and backward through the turntable mechanism 100. An air nozzle suction pipe 5032 is vertically arranged at the bottom of the air nozzle bracket 5031. The air nozzle suction pipe 5032 adopts vacuum adsorption. A step is arranged at the bottom of the suction channel of the air nozzle suction pipe 5032. When the air nozzle suction pipe 5032 sucks the air nozzle, the air nozzle abuts against the step and will not continue to move inward. When installing the air nozzle, the air nozzle vacuum adsorption device 503 extends the air nozzle suction pipe 5032 into the oil tank, and the air nozzle suction pipe 5032 loosens the air nozzle, and the air nozzle falls downward to the installation position.

[0057] The air nozzle installation mechanism 500 further includes an air nozzle screwing assembly 504. The air nozzle screwing assembly 504 and the air nozzle loading platform 502 are arranged along the circumference of the rotating disk 101, and the air nozzle knob assembly is located at the next station of the air nozzle loading platform 502. After the air nozzle is installed in the oil tank, the rotating disk 101 drives the oil tank to rotate to the air nozzle screwing assembly 504, and the air nozzle screwing assembly 504 extends into the oil tank to drive the air nozzle to rotate, so that the thread of the air nozzle peripheral side wall is connected with the oil tank thread.

[0058] When the rotating disk 101 drives the oil tank to rotate to the air nozzle screwing assembly 504, the air cylinder drives the air nozzle screwing assembly 504 to descend, so that the screwing head is set on the air nozzle, and the motor drives the screwing head to rotate, thereby driving the air nozzle to rotate, so that the air nozzle is threadedly connected in the oil tank. The air nozzle screwing assembly 504 adopts the existing technology, and the structure can refer to the air nozzle knob transposition in the patent "CN118789276A A lighter gas outlet structure installation device".

[0059] Since all mounting frames 104 move synchronously, the clamps fixed on all mounting frames 104 operate synchronously, and the trajectory of all clamps grabbing parts from the loading platform and loading them into the oil tank is fixed. The rotating disk 101 rotates at intervals, and the driving disk 105 drives the clamps to complete a set of actions, so that the clamps of each process load the parts into the oil tank on the tooling assembly 700 below it, and then the rotating disk 101 rotates a certain angle to drive the tooling assembly 700 into the next process, and the cycle repeats.

[0060] like Figures 19 to 21 As shown, the tooling assembly 700 includes a tooling body 701 fixed at the bottom edge of the rotating disk 101, and a fixing member 702 and a clamping member 703 for clamping the oil tank are arranged on the tooling body 701. The fixing member 702 is fixed on the tooling body 701, and the clamping member 703 is hinged on the tooling body 701. A tooling spring 704 is arranged between the tooling body 701 and the clamping member 703. The tooling spring 704 pushes one end of the clamping member 703 through elastic force, so that the other end of the clamping member 703 rotates toward the direction of the fixing member 702, thereby clamping and fixing the oil tank.

[0061] The clamping member 703 is in an "L" shape and includes a vertical portion 7031 and a horizontal portion 7032. The middle section of the vertical portion 7031 is hinged to the front end of the tooling body 701 through a rotating shaft. The upper half of the vertical portion 7031 protrudes to the top of the tooling body 701 for clamping the oil tank. The horizontal portion 7032 extends to the bottom of the tooling body 701. The tooling spring 704 is arranged between the bottom of the tooling body 701 and the horizontal portion 7032. The spring pushes the horizontal portion 7032 downward, causing the vertical portion 7031 to rotate toward the direction of the fixing member 702, thereby clamping and fixing the oil tank.

[0062] The tooling assembly 700 also includes a tooling cylinder 705 for compressing the tooling spring 704. When the tooling cylinder 705 compresses the tooling spring 704, that is, overcomes the spring force, the clamping member 703 rotates away from the fixing member 702, thereby loosening the oil tank, and the oil tank can be taken out or put in.

[0063] The tooling cylinder 705 is fixed on the frame 1000 and is located below the rotating disk 101. The piston rod of the tooling cylinder 705 is vertically upward, and an abutment block 706 is fixed on the piston rod. There are five clamping members 703 on the tooling body 701, which can clamp five oil grooves at the same time. Through the abutment block 706, all the clamping members 703 can be pushed upward at the same time to achieve simultaneous clamping or simultaneous release of the five oil grooves.

[0064] The tooling assembly 700 of the present invention provides a clamping force through the tooling spring 704 to achieve dynamic clamping, effectively prevent the oil tank from shaking, and ensure assembly accuracy.

[0065] like Fig. 22 and Fig.23 As shown, the loading clamp 800 includes a clamp body 802 and a clamp driving seat 801. The clamp driving seat 801 is fixed on the frame 1000. A mounting portion 803 is movably provided on the clamp driving seat 801 in a direction parallel to the guide rail 103. The clamp body 802 is movably provided on the mounting portion 803 in a vertical direction, so that the clamp body 802 can move in the vertical direction and the front-to-back direction to transport the oil tank.

[0066] On the clamp driving seat 801, a belt 804 wheel is connected to the conveying shaft of the motor, and the mounting portion 803 is fixed to the belt 804, thereby driving the mounting portion 803 to move along the track. A lifting cylinder 805 is vertically arranged at the top of the mounting portion 803, and the clamp body 802 is fixed to the piston rod of the lifting cylinder 805, thereby driving the clamp body 802 to vertically lift along the track.

[0067] An abutment plate 806 and a clamping portion 807 are provided on the clamping jaw body 802. The clamping portion 807 includes a clamping bracket 8071 movably arranged on the clamping jaw body 802. A clamping plate 8072 is hinged on the clamping bracket 8071. A clamping spring 8073 is provided between the clamping plate 8072 and the clamping bracket 8071 on the side away from the abutment plate 806. A clamping cylinder 808 for driving the clamping portion 807 to move is provided on the clamping jaw body 802. The clamping cylinder 808 drives the clamping portion 807 to move toward the abutment plate 806. The clamping spring 8073 abuts against the clamping plate 8072, so that the clamping plate 8072 and the abutment plate 806 clamp and fix the oil tank.

[0068] The feeding clamping jaw 800 of the present invention provides clamping force through the clamping spring 8073, thereby realizing adaptive adjustment of the clamping force, thereby ensuring sufficient clamping stability and being applicable to oil tanks of different sizes.

[0069] The present invention also provides a material detection component on the frame 1000, and the material detection component includes a laser detector 2100 arranged on one side of the first ferry plate 900. The laser detector 2100 emits a laser toward each oil tank on the socket 901. When a laser is not blocked, it is determined that an oil tank is missing at the slot, and the staff can pause the equipment to manually refill the material.

[0070] The working process of this embodiment is as follows: The staff places the tray 2000 filled with oil tanks on the empty tray transfer mechanism 600, and the loading clamp 800 grabs the oil tanks into the first ferry tray 900. The grabbed empty tray 2000 moves along the empty tray transfer mechanism 600 to the second conveyor belt 602, and the first transport clamp 1800 grabs the oil tanks in the first ferry tray 900 into the tooling assembly 700, thereby completing the loading of the oil tanks.

[0071] The turntable mechanism 100 drives the tooling assembly 700 to rotate, so that the oil tank passes through the zinc sleeve installation mechanism 200, the cotton rod installation mechanism 300, the cotton piece installation mechanism 400, and the air nozzle installation mechanism 500 in sequence, so that the zinc sleeve, the cotton rod, the cotton piece and the air nozzle are installed in the oil tank in sequence to complete the assembly of the oil tank.

[0072] Finally, the second transport clamp 1900 grabs the assembled oil tank on the tooling assembly 700 and puts it into the second ferry tray 1700, and the unloading clamp 1600 grabs the oil tank from the second ferry tray 1700 and puts it into the empty tray 2000 on the empty tray transfer mechanism 600, completing the unloading of the oil tank.
