DETAILED DESCRIPTION

[0021] The assembly device of the fire extinguisher cylinder includes an upper corrector 4, a lower corrector 5, a grab assembly A10, a grab assembly B11, a press assembly 6, a welding assembly 7 and a transport box 8 (see the attached manual). Figure 1 ).

[0022] The pressing assembly 6 includes a bottle conveyor 13, a guide slide 14, an upper end cap feeder 18, a lower end cap feeder 19 and a positioning seat 17 (see the attached manual). Fig.16 ). A guide slide 14 is installed at one end of the bottle conveyor 13; a push plate 16 is installed on the bottle conveyor 13 above the guide slide 14 through a push cylinder 15. The bottle conveyor 13 is an outsourced component and can convey the component bottle body of the fire cylinder when it is working.

[0023] When the bottle body conveyor 13 conveys the bottle body 1 to the position corresponding to the guide slide 14 during operation, the pushing cylinder 15 can push the bottle body 1 onto the guide slide 14 through the pushing plate 16 and roll the bottle body 1 onto the positioning seat 17 under the guidance of the pushing plate 16 .

[0024] A positioning seat 17 is provided below the guide slide 14 (see the attached manual). Fig.16 ); The positioning seat 17 includes an arc-shaped support 20 and a limit baffle 21; two sets of arc-shaped supports 20 are symmetrically arranged on one side of the limit baffle 21 (see the attached specification Fig.16 ).

[0025] The curvature of the arc-shaped opening of the arc-shaped support 20 is consistent with the curvature of the circumferential surface of the bottle body 1. In this way, when the bottle body rolls onto the arc-shaped support 20, the arc-shaped support 20 can provide support for the bottle body 1 through the arc-shaped opening.

[0026] An upper end cap feeder 18 is mounted on one side of the positioning seat 17, and a lower end cap feeder 19 is mounted on the other side of the positioning seat 17 (see the attached manual). Fig.16 ).

[0027] The upper end feeder 18 and the lower end feeder 19 include a feeding conveyor belt 22, a gripping claw 33, a feeding plate 26 and a positioning cylinder 25 (see the attached manual). Fig.17 ).

[0028] A positioning plate 23 is installed at one end of the feeding conveyor belt 22; a grabbing position 24 is set on the positioning plate 23; a feeding plate 26 is installed at one end of the positioning plate 23 through a positioning cylinder 25; a transverse slide 29 is slidably installed on one side of the positioning plate 23 through a base 27 and a screw mechanism 28; a lifting slider 31 is installed on the transverse slide 29 through a lifting cylinder 30; a clamping claw 33 is installed on the lifting slider 31 through a rotating cylinder 32.

[0029] During operation, after the feeding conveyor belt 22 delivers the workpiece to the positioning plate 23, the positioning cylinder 25 can push the workpiece to the grabbing position 24 through the feeding plate 26. Then, under the cooperation of the screw mechanism 28, the lifting cylinder 30 and the rotating cylinder 32, the gripping claw 33 can grab the workpiece from the grabbing position 24 and drive it to move along the trajectory.

[0030] One side of the press-fit assembly 6 is connected to the upper corrector 4 and the lower corrector 5 (see the attached manual). Figure 1The lower corrector 5 includes a plate chain hoist 48, a limit bar 49 and a conveyor A57 (see the attached manual). Figure 2 , 3 and 4).

[0031] The plate chain hoist 48 comprises a base 51, a transmission mechanism 52 and a guide slide 56. The base 51 is provided with a hoisting plate chain 53 (see the appendix of the specification) in an overall "L"-shaped structure through the transmission mechanism 52. Figure 5 ).

[0032] The transmission mechanism 52 includes a driving sprocket 58, a driven sprocket 60, a reversing sprocket 62, and a transmission chain 63 (see the attached manual). Figure 5 Two sets of driving sprockets 58 are symmetrically installed in the machine base 51 through the motor and the driving shaft 69; two sets of driven sprockets 60 are symmetrically installed on the machine base 51 below the driving sprocket 58 through the driven shaft 59; two sets of reversing sprockets 62 are symmetrically installed between the driving sprocket 58 and the driven sprocket 60 through the reversing shaft 61; a transmission chain 63 is installed between the corresponding driving sprocket 58, the driven sprocket 60 and the reversing sprocket 62; a lifting plate chain 53 (see the attached manual) is installed between the transmission chains 63. Figure 3 , 4 and 5).

[0033] The purpose of setting the transmission mechanism 52 in this way is to enable the motor to drive the driving shaft 69 and the driving sprocket 58 to rotate during operation, and the driving sprocket 58 can drive the lifting plate chain 53 to rotate synchronously with the cooperation of the reversing sprocket 62, the driven sprocket 60 and the transmission chain 63.

[0034] A plurality of guide rollers 65 are provided at intervals on one side of the transmission chain 63; the guide rollers 65 are movably connected to the guide grooves 66 provided on the base 51 (see the attached manual). Figure 2 and 8 The purpose of setting the guide roller 65 and the guide slot 66 is to enable the transmission chain 63 to move along a fixed track in cooperation with the guide roller 65 and the guide slot 66 during the process of the transmission chain 63 driving the lifting plate chain 53 to rotate, so as to avoid the lifting plate chain 53 from deviating from the movement track.

[0035] A storage hopper 54 is installed above the lower end of the lifting plate chain 53; the upper end of the lifting plate chain 53 passes through the storage hopper 54 and extends to the upper end of the machine base 51; during operation, the lower head 3 can be placed in the storage hopper 54 at will.

[0036] A plurality of limit strips 49 are installed at intervals on the lifting plate chain 53 (see the attached manual). Figure 5 , 6The purpose of setting the lifting plate chain 53 is to utilize the characteristics of the bottom of the lower head 3 being heavy and the upper end being light. When the lifting plate chain 53 drives the limit bar 49 to rotate, if the bottom of the lower head 3 rests on the limit bar 49, the lower head 3 will fit tightly on the lifting plate chain 53 under the action of gravity, and drive the limit bar 49 to move together with it (see the attached manual). Figure 6 ). When the upper end of the lower end cover 3 is placed on the limit strip 49, the lower end cover 3 will flip outwards under the action of gravity, break away from the limit strip 49 and return to the storage hopper 54.

[0037] A guide slide 56 is mounted on the base 51 at one side of the upper end of the lifting plate chain 53; a conveyor A57 is arranged below the guide slide 56 (see the attached manual). Figure 3 and 4 The purpose of setting the guide slide 56 is to make the bottom of the lower head 3 contact with the guide slide 56 after it is out of contact with the lifting plate chain 53 during operation and finally enter the conveyor A57 under its guidance, so that the conveyor A57 can uniformly output the lower heads 3 with the bottom facing downward.

[0038] The upper corrector 4 includes a plate chain hoist 48, a conveyor B68 and an adsorption magnet 67 (see the attached manual). Fig. 9 , 10 and 11). A plurality of adsorption magnets 67 are installed at intervals on the lifting plate chain 53 of the plate chain lifting machine 48 of the upper corrector 4; the diameter of the adsorption magnet 67 is consistent with the diameter of the upper port of the upper head 2.

[0039] The purpose of setting the adsorption magnet 67 in this way is that when it is working, when the upper port of the upper head 2 is attached to the adsorption magnet 67, the contact area between the adsorption magnet 67 and the upper head 2 is relatively large, and its adsorption force is relatively large, so that the upper head 2 can be driven to move together. When other positions of the upper head 2 such as the lower port are in contact with the adsorption magnet 67, since the diameter of the lower port is much larger than the diameter of the adsorption magnet 67, only a part of the adsorption magnet 67 can be in contact with the lower port of the upper head 2, resulting in a small magnetic force between the lower port of the upper head 2 and the adsorption magnet 67. In this way, during the rotation of the lifting plate chain 53, it will not be able to overcome gravity and drive the upper head 2 to move together; so far, the rotation process of the lifting plate chain 53 can only drive the upper port in contact with it to move together through the adsorption magnet 67 (see the attached manual Fig. 9 and 10 ).

[0040] One end of the plate chain hoist 48 of the upper corrector 4 is provided with a conveyor B68 (see the attached manual). Fig.11 and 12 ).

[0041] The conveyor B68 includes an upper horizontal conveying section 64 , a lower horizontal conveying section 50 and a reversing slope section 55 ; a reversing slope section 55 is arranged between the upper horizontal conveying section 64 and the lower horizontal conveying section 50 .

[0042] The purpose of setting up the conveyor B68 is to make the upper end cap 2 move with the plate chain hoist 48, and the upper end cap 2 will eventually enter the conveyor B68 under the guidance of the guide slide 56 in a way that the lower end cap 2 contacts the upper horizontal conveying section 64. After the upper end cap 2 enters the conveyor B68 in a way that the lower end cap 2 contacts the upper horizontal conveying section 64, the upper horizontal conveying section 64 drives the upper end cap 2 to move, and when it passes through the reversing slope section 55, the upper end cap 2 will turn over along the reversing slope section 55 under the action of gravity and finally engage with the lower horizontal conveying section 50 with the large end cap facing downward, and be transported backward with the lower horizontal conveying section 50 (see the attached manual). Fig.12 ), so as to achieve the purpose of correcting the posture of the upper head 2.

[0043] When the upper corrector 4 is working, the upper end cap 2 can be conveyed to the feeding conveyor 22 of the upper end cap feeder 18 through the conveyor B68 with the large port facing downward. When the lower corrector 5 is working, the lower end cap 3 can be conveyed to the feeding conveyor 22 of the lower end cap feeder 19 with the bottom facing downward.

[0044] A transport box 8 (see the attached manual) is installed between the press-fit assembly 6 and the upper and lower correctors 4 and 5 through a chain conveyor 9. Fig.15 The two ends of the transport box body 8 are provided with a clamping avoidance groove 12 (see the attached manual). Fig.15 ). When working, the grabbing assembly A10 can clamp the workpiece from the positioning seat 17 and place it in the transport box 8. The purpose of setting the clamping avoidance groove 12 is to enable the clamping slide bar 46 of the grabbing assembly A10 to clamp the workpiece from both ends and then place the workpiece on the transport box 8 from the clamping avoidance groove 12. Then the transport box 8 can drive the workpiece to move and complete the transfer work.

[0045] A welding assembly 7 is provided at one end of the chain conveyor 9 (see the attached manual). Fig.15 The welding assembly 7 includes an assembly base 34, an automatic welding robot 39, an extrusion sleeve 38 and a drive motor 37 (see the attached manual). Fig.18 ).

[0046] The assembly base 34 is symmetrically provided with a transverse slide 29 via a transverse cylinder 35; the transverse slide 29 is provided with an extrusion sleeve 38 via a drive motor 37; the extrusion sleeve 38 is symmetrically provided with an extrusion avoidance opening 40 (see the appendix of the specification) Fig.18). Two groups of automatic welding robots 39 are symmetrically installed on one side of the transverse slide 29. During operation, the extrusion sleeve 38 can tighten the workpiece from both ends, and with the cooperation of the drive motor 37, the extrusion sleeve 38 can drive the workpiece to rotate freely. During the rotation of the workpiece, the automatic welding robot 39 can complete the welding work of the workpiece.

[0047] A grabbing assembly A10 is installed above the press-fit assembly 6 and the chain conveyor 9; a grabbing assembly B11 is installed above the welding assembly 7 and the chain conveyor 9 (see the attached manual). Fig.13 and 14 ).

[0048] The grabbing assembly A10 and the grabbing assembly B11 both include a frame 41, a control cylinder 42, a longitudinal slide 43, a lifting cylinder 44, an upper and lower slide seat 45 and a clamping slide rod 46 (see the attached manual). Fig.19 ).

[0049] A longitudinal slide 43 is mounted on the frame 41 through a control cylinder 42; an upper and lower slide seat 45 is mounted on the longitudinal slide 43 through a lifting cylinder 44 and a guide slide rod; two groups of clamping slide rods 46 are symmetrically mounted on the upper and lower slide seats 45 through guide rails; a control screw 36 is mounted between the clamping slide rods 46 through a screw motor 47; the control screw 36 is connected to the corresponding clamping slide rod 46; when the control screw 36 rotates forward, the clamping slide rods 46 move closer to each other; when the control screw 36 rotates reversely, the clamping slide rods 46 separate from each other. When working, the clamping slide rod 46 can complete the work of transferring the workpiece under the cooperation of the control cylinder 42, the screw motor 47 and the lifting cylinder 44.

[0050] The assembly device of the fire extinguisher cylinder is such that the upper corrector 4 and the lower corrector 5 are firstly actuated during operation.

[0051] When the upper corrector 4 is working, firstly, a plurality of upper heads 2 are randomly placed in the storage hopper 54, and then the plate chain elevator 48 and the conveyor B68 of the upper corrector 4 are started. In this process, since the upper port of the upper head 2 is attached to the adsorption magnet 67, the contact area between the adsorption magnet 67 and the upper head 2 is relatively large, and its adsorption force is relatively large, so the upper head 2 can be driven to move together. When other positions of the upper head 2, such as the lower port, contact the adsorption magnet 67, the magnetic force between the lower port of the upper head 2 and the adsorption magnet 67 is small, and it will not be able to overcome gravity to drive the upper head 2 to move together; so far, the lifting plate chain 53 can only drive the upper port to move together with the upper head 2 in contact with it through the adsorption magnet 67 during the rotation process.

[0052] When the lifting plate chain 53 drives the upper port to move together with the upper head 2 in contact with it through the adsorption magnet 67 and contacts with the guide slide 56, under its guidance, it will enter the conveyor B68 in a manner that the lower port contacts with the upper horizontal conveying section 64.

[0053] When the upper end cap 2 enters the conveyor B68 in a manner that the lower end port contacts the upper horizontal conveying section 64, the upper horizontal conveying section 64 drives the upper end cap 2 to move. When it passes through the reversing slope section 55, the upper end cap 2 will be turned over along the reversing slope section 55 under the action of gravity and finally be buckled on the lower horizontal conveying section 50 with the large end port facing downward, and be conveyed backward along with the lower horizontal conveying section 50 (see the attached manual). Fig.12 ), so as to achieve the purpose of correcting the posture of the upper head 2.

[0054] When the lower corrector 5 is working, firstly, a plurality of lower heads 3 are randomly placed in the storage hopper 54. Then, the plate chain elevator 48 and the conveyor A57 of the lower corrector 5 are started. When the plate chain elevator 48 is working, if the bottom of the lower head 3 is placed on the limit bar 49, the lower head 3 will be closely attached to the lifting plate chain 53 under the action of gravity, and driven to move together with the limit bar 49 (see the appendix of the manual). Figure 6 ). When the upper port of the lower end cap 3 is placed on the limit bar 49, the lower end cap 3 will flip outward under the action of gravity, break away from the limit bar 49 and return to the storage hopper 54. In this way, the plate chain elevator 48 will drive the lower end cap 3 expected to be in contact with the bottom to move together and finally guide the slide plate 56 to contact and finally enter the conveyor A57 under its guidance. In this way, the conveyor A57 can uniformly output the lower end caps 3 with the bottom facing downward. At this point, the lower corrector 5 can achieve the purpose of correcting the posture of the lower end cap 3.

[0055] When the upper corrector 4 is working, the upper end cap 2 can be conveyed to the feeding conveyor 22 of the upper end cap feeder 18 through the conveyor B68 with the large port facing downward. When the lower corrector 5 is working, the lower end cap 3 can be conveyed to the feeding conveyor 22 of the lower end cap feeder 19 with the bottom facing downward.

[0056] After the above process is completed, the bottle body conveyor 13 conveys the bottle body to the position corresponding to the guide slide 14, and then the pushing cylinder 15 pushes the bottle body onto the guide slide 14 through the pushing plate 16, and the bottle body rolls onto the positioning seat 17 under the guidance of the pushing plate 16.

[0057] When the bottle body rolls onto the positioning seat 17, the feeding conveyor belt 22 of the upper head feeder 18 conveys the upper head 2 to the positioning plate 23, and then the positioning cylinder 25 pushes the workpiece to the grabbing position 24 through the feeding plate 26. Then, with the cooperation of the screw mechanism 28, the lifting cylinder 30 and the rotating cylinder 32, the clamping claw 33 can grab the upper head 2 from the grabbing position 24 and drive the upper head 2 to rotate to correspond to one end of the bottle body 1. At the same time, the lower head feeder 19 will grab the lower head 3 through the clamping claw 33 and drive the lower head 3 to rotate to correspond to the other end of the bottle body 1.

[0058] When the upper end cap 2 and the lower end cap 3 correspond to the two ends of the bottle body 1, the screw mechanism 28 of the upper end cap feeder 18 and the lower end cap feeder 19 is actuated, so that the clamping claws 33 can drive the upper end cap 2 and the lower end cap 3 to be plugged into the two ends of the bottle body 1. After the upper end cap 2 and the lower end cap 3 are plugged into the two ends of the bottle body 1, the upper end cap 2 and the lower end cap 3 will form an integral structure with the bottle body 1, i.e., a pre-assembled fire cylinder.

[0059] After the upper end feeder 18 and the lower end feeder 19 complete the assembly of the pre-assembled fire cylinder, they will reset and enter the next working cycle. Then, the grabbing assembly A10 clamps the pre-assembled fire cylinder from both ends through the clamping slide bar 46, and then the grabbing assembly A10 places the pre-assembled fire cylinder on the transfer box 8 through the clamping avoidance groove 12. Then, the chain conveyor 9 drives the transfer box 8 to move to correspond to the welding assembly 7.

[0060] When the transport box 8 moves to correspond to the welding assembly 7, the grab assembly B11 grabs the pre-assembled fire cylinder from the transport box 8 through the clamping slide 46 and places it between the extrusion sleeves 38 of the welding assembly 7. At this time, the clamping slide 46 corresponds to the extrusion avoidance opening 40 on the extrusion sleeve 38. Then the traverse cylinder 35 drives the extrusion sleeve 38 to move through the traverse slide 29, so that the extrusion sleeve 38 tightens and fixes the pre-assembled fire cylinder clamp from both ends. Then the grab assembly B11 is reset.

[0061] After the extrusion sleeve 38 tightens and fixes the pre-assembled fire cylinder clamp, the driving motor 37 drives the pre-assembled fire cylinder to rotate freely through the extrusion sleeve 38. During the free rotation of the pre-assembled fire cylinder, the automatic welding robot 39 can complete the welding work of the workpiece. At this point, the assembly device of the fire extinguisher cylinder can complete the installation and welding work of the fire cylinder. After the welding of the fire cylinder is completed, the grabbing component B11 transfers the welded cylinder to the next process, and the assembly device of the fire extinguisher cylinder can enter the next production process.
