[0025] Reference Figures 1 to 10 In the first aspect, embodiments of the present invention propose an automatic assembly machine for spray booms, which can automatically assemble spray boom workpieces, greatly improving the production efficiency of spray boom workpieces and ensuring product quality.

[0026] The automatic spray boom assembly machine of this invention can automatically assemble the outer tube 910, the first connector 920, the second connector 930, and the inner tube 940 into a spray boom workpiece. (Refer to...) Figure 11 The system comprises a first connector 920 located at the outlet end of the outer pipe 910, a second connector 930 connected to the inlet end of the outer pipe 910, an inner pipe 940 inserted within the outer pipe 910, and an outlet end of the inner pipe 940 flush with the end face of the first connector 920.

In use, the air inlet is connected to an external air supply device, and the water inlet is connected to an external water supply device.

[0027] Reference Figure 1The automatic spray bar assembly machine includes a feeding assembly, a conveying assembly 100, and an assembly assembly 600. The conveying assembly 100 is equipped with at least one conveyor seat 110, which has a positioning hole for inserting an outer tube 910. The feeding assembly includes a first feeder 200, a second feeder 300, a third feeder 400, and a fourth feeder 500. The conveyor seat 110 of the conveying assembly 100 can sequentially pass through the first feeder 200, the second feeder 300, the third feeder 400, and the fourth feeder 500.

[0028] The first feeder 200 is used to feed the outer tube 910, the second feeder 300 is used to feed the first connector 920 and connects the first connector 920 to the outlet end of the outer tube 910, the third feeder 400 is used to feed the second connector 930 and connects the second connector 930 to the inlet end of the outer tube 910, and the fourth feeder 500 is used to feed the inner tube 940, which can be inserted inside the outer tube 910.

[0029] Assembly component 600 is located on the outlet side of fourth feeder 500. After feeding is completed, the conveyor seat 110 corresponding to conveyor component 100 moves to assembly component 600. Assembly component 600 is used to rivet and reinforce the components in the spray bar workpiece to prevent the inner tube 940 from coming out of the outer tube 910. Assembly component 600 includes a first pressing component 610 and a riveting component. The first pressing component 610 is located above conveyor component 100, and the riveting component is located below conveyor component 100. The first pressing component 610 can press down the spray bar workpiece located on conveyor seat 110, so that the lower end of the spray bar workpiece extends into the riveting position corresponding to the riveting component. The riveting component can apply pressure to the outer periphery of outer tube 910, so that outer tube 910 and inner tube 940 are riveted and fixed.

[0030] In some embodiments, the conveying assembly 100 is provided with a conveying disk, and the conveying seat 110 is arranged around the central circumference of the conveying disk. The rotation of the conveying disk allows the conveying seat 110 to move sequentially past the first feeder 200, the second feeder 300, the third feeder 400, the fourth feeder 500, and the assembly assembly 600.

[0031] In some embodiments, refer to Figure 2The first feeder 200 includes a first support 270, a first hopper 220, a first drive component 240, a first distribution plate 230, and a first gripper 250. The first support 270 is disposed on the side of the conveying assembly 100. The first hopper 220, the first drive component 240, and the first gripper 250 are respectively connected and installed on the first support 270. The first hopper is used to place the outer tube 910. The outer periphery of the first distribution plate 230 is provided with at least one first groove, and the first groove is connected to the outer... The surface of the tube 910 is fitted with the outlet end of the first hopper 220, which is located above the first distribution plate 230. The output end of the first drive component 240 is connected to the first distribution plate 230. Under the driving action of the first drive component 240, the first distribution plate 230 rotates, and the first groove can rotate from the upper end of the first distribution plate 230 to the lower end of the first distribution plate 230, that is, the outer tubes 910 can be transferred one by one from the upper end to the lower end of the first distribution plate 230. The first pneumatic gripper 250 is located below the first distribution plate 230 and can clamp the outer tubes 910 located in the first groove at the lower end of the first distribution plate 230 and clamp the outer tubes 910 onto the conveyor seat 110.

[0032] In some embodiments, the first feeder 200 further includes a first flipping component, which is mounted on the first bracket 270 and its output end is connected to the first pneumatic gripper 250, enabling the first pneumatic gripper 250 to rotate. It is understood that after the first pneumatic gripper 250 clamps the outer tube 910, the first flipping component drives the first pneumatic gripper 250 to flip, allowing the horizontally positioned outer tube 910 to rotate and be inserted into the positioning hole of the conveyor seat 110 in a vertically positioned manner.

[0033] In some embodiments, the first feeder 200 further includes a first lifting component 260, which is mounted on the first bracket 270. Its output end is connected to the first flipping component and can drive the first flipping component and the first pneumatic gripper 250 to move in the vertical direction. After the first pneumatic gripper 250 clamps the outer tube 910 and flips the outer tube 910 to a vertical position, it can adjust the position of the outer tube 910 in the vertical direction so that the outer tube 910 can be smoothly inserted into the positioning hole.

[0034] In some embodiments, refer to Figure 1The automatic spray bar assembly machine also includes a positioning component 210, which includes a seventh drive component and a positioning rod. The output end of the seventh drive component is connected to the positioning rod, enabling it to drive the positioning rod to move vertically. After the first feeder 200 completes the feeding of the outer tube 910, the outer tube 910 moves with the conveyor seat 110 to below the positioning component 210. Under the driving action of the seventh drive component, the positioning rod moves downward, causing the outer tube 910 to move downward in the positioning hole of the conveyor seat 110 until the lower end of the positioning rod moves to a preset height, ensuring that the outer tube 910 is at a uniform height when entering the station of the second feeder 300, so as to facilitate the subsequent installation of the first connector 920 on the outer tube 910.

[0035] In some embodiments, refer to Figure 3 The second feeder 300 includes a third support 390, a first vibrating disc 330, a first track 370, a first pushing component 350, a first slider 360, and a second pressing component 340. The first vibrating disc 330, the first track 370, the first pushing component 350, and the second pressing component 340 are respectively connected to the third support 390. The first slider 360 is slidably connected to the first track 370 and is located above the conveying assembly 100. The first slider 360 is provided with a first through hole. The output end of the first pushing component 350 is connected to the first slider 360. The second pressing component 340 is located above the conveying assembly 100 and above the first slider 360. The outlet end of the first vibrating disc 330 faces the first slider 360, and the first vibrating disc 330 can feed a first connector 920 into the first through hole of the first slider 360. Driven by the first pushing component 350, the first slider 360 can move along the extension direction of the first track 370, causing the first connector 920, which falls into the first through hole, to move with the first slider 360 from the outlet end of the first vibrating plate 330 to below the second pressing component 340. The second pressing component 340 is provided with a pressing rod that can move up and down. The pressing rod can drive the first connector 920 located at the first through hole to move downward to the upper end of the outer tube 910 on the conveying seat 110, and make the connection between the first connector 920 and the outer tube 910 stable.

[0036] Furthermore, a first support plate is connected to the lower end of the first track 370, and the first slider 360 is slidably connected to the upper surface of the first support plate. The first support plate extends from the lower end of the outlet of the first vibrating plate 330 toward the conveying assembly 100. During the movement of the first slider 360, the lower end of the first through hole is blocked by the first support plate to prevent the first connector 920 from falling downward. When the first through hole of the first slider 360 moves to above the conveying seat 110, the lower end of the first through hole is not blocked by the first support plate, and the first connector 920 moves downward to the upper end of the outer tube 910 by the downward pressing action of the second pressing component 340.

[0037] Furthermore, the second feeder 300 also includes a first buffer spring 380, which is connected to the third bracket 390. The first buffer spring 380 is located below the conveying assembly 100. When the second pressing component 340 presses down on the first connector 920, the upper end of the first buffer spring 380 provides a buffering force to the lower end of the outer tube 910.

[0038] In some embodiments, refer to Figure 1 The automatic spray bar assembly machine also includes a punching component 320, which punches holes in the first connector 920, enabling the produced spray bar workpieces to achieve a mist-like water spraying effect during use. The punching component 320 is located on the outlet side of the second feeder 300. After passing through the second feeder 300, the conveyor seat 110 on the conveying component 100 enters the punching station where the punching component 320 is located. The punching component 320 includes a fourth bracket 323, a third drive component 321, and a punch 322. The fourth bracket 323 is located on the side of the conveying component 100, the third drive component 321 is connected to the fourth bracket 323, and the punch 322 is located above the conveying component 100. The output end of the third drive component 321 is connected to the punch 322, and the punch 322 can move vertically under the driving action of the third drive component 321. It is understandable that during the downward movement of the punch 322, the first connector 920 on the conveyor seat 110 can be punched, so that at least one punch is formed on the first connector 920.

[0039] Furthermore, refer to Figure 4 The punching assembly 320 also includes a support base 324, which is located below the punch 322 and is used to support the lower end of the outer tube 910 to prevent the outer tube 910 from shifting downwards during the punching process.

[0040] Furthermore, refer to Figure 1 The automatic spray bar assembly machine also includes a first detection component 310, which is located between the second feeder 300 and the punching component 320. It can detect whether the outer tube 910 is connected to the first connector 920, so as to facilitate the subsequent removal of defective products.

[0041] In some embodiments, refer to Figure 5The third feeder 400 includes a fifth support 480, a second vibrating disc 420, a second track 460, a second pushing component 440, a second slider 450, and a first lifting component 430. The second vibrating disc 420, the second track 460, the second pushing component 440, and the first lifting component 430 are respectively connected to the fifth support 480. The outlet end of the second vibrating disc 420 faces the second slider 450 and is used to provide a second connector 930 to the second slider 450. The second slider 450 is provided with a second through hole penetrating its upper and lower surfaces. The second slider 450 is slidably connected to the second track 460. The output end of the second pushing component 440 is connected to the second slider 450. Under the driving action of the second pushing component 440, the second slider 450 can move along the second track 460, causing the second through hole to move back and forth between the outlet end of the second vibrating disc 420 and the top of the first lifting component 430. The first lifting component 430 is located below the conveying assembly 100. When the second slider 450 moves to the lower part of the conveying seat 110 of the conveying assembly 100, the first lifting component 430 can lift the second connector 930 at the second through hole upward to the lower end of the outer tube 910 on the conveying seat 110, so that the second connector 930 is connected to the outer tube 910.

[0042] Furthermore, a second support plate is connected to the lower end of the second track 460, and the second slider 450 is slidably connected to the upper surface of the second support plate. The second support plate extends from the lower end of the outlet of the second vibrating disc 420 toward the conveying assembly 100. During the movement of the second slider 450, the lower end of the second through hole is blocked by the second support plate to prevent the second connector 930 from falling downward. When the second through hole of the second slider 450 moves to below the conveying seat 110, the lower end of the second through hole is not blocked by the second support plate, and the first lifting component 430 can pass upward through the second support plate and contact the second connector 930 located at the second through hole. The second connector 930 moves upward to the lower end of the outer tube 910 by the lifting action of the first lifting component 430.

[0043] Furthermore, the third feeder 400 also includes a second buffer spring 470, which is connected to the fifth bracket 480. The second buffer spring 470 is positioned above the conveying assembly 100. When the first lifting component 430 presses down on the second connector 930, the upper end of the second buffer spring 470 provides a buffering force to the upper end of the outer tube 910.

[0044] In some embodiments, refer to Figure 1The automatic spray bar assembly machine also includes an adjustment assembly 410, which includes an eighth drive component and an adjustment rod. The output end of the eighth drive component is connected to the adjustment rod, enabling it to move the adjustment rod vertically. The adjustment rod is located above the conveying assembly 100. After the third feeder 400 completes the feeding of the second connector 930, the outer tube 910 moves with the conveying seat 110 to below the adjustment rod. Under the driving action of the eighth drive component, the adjustment rod moves downward, causing the outer tube 910, which is connected to the first connector 920 and the second connector 930, to move downward in the positioning hole of the conveying seat 110 until the lower end of the adjustment rod moves to a preset height. This ensures that the outer tube 910 is at a uniform height when it enters the station of the fourth feeder 500, facilitating the subsequent installation of the inner tube 940 inside the outer tube 910.

[0045] In some embodiments, refer to Figure 6 The fourth feeder 500 includes a second support 580, a second hopper 520, a second drive component 540, a second distribution plate 530, and a second pneumatic gripper 550. The second support 580 is disposed on the side of the conveying assembly 100, and the second hopper, the second drive component 540, and the second pneumatic gripper 550 are respectively connected to the second support 580. The second hopper 520 is used to hold the inner tube 940, and the outlet end of the second hopper 520 is located above the second distribution plate 530, allowing the inner tube 940 to be fed into the second distribution plate 530. At least one second groove is provided on the outer periphery of the second distribution plate 530, and the second groove mates with the surface of the inner tube 940. When the inner tube 940 in the second hopper 520 falls onto the second distribution plate 530, it can be separated by the second groove. The output end of the second driving component 540 is connected to the second distributing plate 530. Under the driving action of the second driving component 540, the second distributing plate 530 rotates, causing the second groove to rotate from the upper end of the second distributing plate 530 to the lower end, thereby allowing the inner tubes 940 to move one by one to the lower end of the second distributing plate 530. The second pneumatic gripper 550 is located below the second distributing plate 530 and can clamp the inner tubes 940 in the second groove at the lower end of the second distributing plate 530, and transfer the inner tubes 940 to the conveying seat 110, allowing the inner tubes 940 to be inserted into the interior of the outer tube 910.

[0046] In some embodiments, the fourth feeder 500 further includes a second flipping component, which is mounted on the second bracket 580 and its output end is connected to the second pneumatic gripper 550, enabling the second pneumatic gripper 550 to rotate. It is understood that after the second pneumatic gripper 550 clamps the inner tube 940, the second flipping component drives the second pneumatic gripper 550 to flip, allowing the horizontally positioned inner tube 940 to rotate and be inserted vertically into the outer tube 910 of the conveyor seat 110.

[0047] In some embodiments, the fourth feeder 500 further includes a second lifting component 560, which is mounted on the second bracket 580. Its output end is connected to the second flipping component, which can drive the second flipping component and the second pneumatic gripper 550 to move in the vertical direction. After the second pneumatic gripper 550 clamps the outer tube 910 and flips the inner tube 940 to a vertical position, it can adjust the position of the inner tube 940 in the vertical direction so that the inner tube 940 can be smoothly inserted into the outer tube 910.

[0048] In some embodiments, both the first drive component 240 and the second drive component 540 are servo motors.

[0049] In some embodiments, the fourth feeder 500 further includes a third pneumatic gripper 570, which is disposed above the conveying assembly 100 and can clamp the outer tube 910 located on the conveying seat 110. It can position the outer tube 910 to prevent the outer tube 910 from moving downward during the insertion of the inner tube 940, so as to facilitate the smooth insertion of the inner tube 940.

[0050] In some embodiments, refer to Figure 1 The automatic spray bar assembly machine also includes a flattening component 510, which can position the relative positions of the inner tube 940 and the outer tube 910, making the upper end face of the inner tube 940 flush with the upper end face of the first connector 920. (Refer to...) Figure 10 The flattening assembly 510 includes a third pressing component 511 and a second lifting component 512. The third pressing component 511 is located above the conveying assembly 100, and the second lifting component 512 is located below the conveying assembly 100. When positioning the inner tube 940, the third pressing component 511 and the second lifting component 512 can operate simultaneously. The output shaft of the third pressing component 511 moves downward and presses the inner tube 940 down to a preset position, while the output shaft of the second lifting component 512 moves upward. The output shaft of the second lifting component 512 is provided with a clearance hole. During the downward movement of the inner tube 940 and the upward movement of the output shaft of the second lifting component 512, the lower end of the inner tube 940 can enter the clearance hole, and the output shaft of the second lifting component 512 can abut against the second connector 930 installed at the lower end of the outer tube 910, thereby restricting the position of the second connector 930 and the outer tube 910 and preventing the outer tube 910 from moving downward as the inner tube 940 moves downward.

[0051] In some embodiments, refer to Figure 7 and Figure 8The riveting component includes a ninth bracket 650, a riveting seat 620, a fourth drive component 640, multiple actuating rods 660, and multiple swing rods 630. The fourth drive component 640 and the riveting seat 620 are both mounted on the ninth bracket 650. The multiple actuating rods 660 are arranged around the central circumference of the riveting seat 620. Each actuating rod 660 extends along the riveting seat 620 and can move radially along the riveting seat 620. The swing rods are rotatably connected to the riveting seat 620 and are arranged in a one-to-one correspondence with the actuating rods 660. One end of the swing rod 630 is movably connected to the end of the actuating rod 660 away from the center of the riveting seat 620, and the other end is connected to the output end of the fourth drive component 640. Under the driving action of the fourth drive component 640, the swing rod 630 can rotate relative to the riveting seat 620 and drive the actuating rods 660 to move closer to or away from the center of the riveting seat 620 radially.

[0052] In some embodiments, four actuating rods 660 and four swing rods 630 are respectively provided. The four actuating rods 660 are evenly arranged around the central circumference of the riveting seat 620. The fourth driving component 640 can simultaneously drive the four swing rods 630 to swing and drive the four actuating rods 660 to simultaneously move closer to or away from the center of the riveting seat 620. After the first pressing component 610 presses down the spray bar workpiece, the four actuating rods 660 move simultaneously towards the spray bar workpiece under the driving action of the fourth driving component 640, and cause the outer tube 910 of the spray bar workpiece to form a pressure point that is recessed inward. The outer tube 910 and the inner tube 940 disposed inside the outer tube 910 are riveted and fixed through the pressure point.

[0053] In some embodiments, the fourth driving component 640 is a cylinder, and its output end is connected to a frustum 641. The upper diameter of the frustum 641 is smaller than the lower diameter. A third roller 631 is connected to the lower end of the rocker arm 630. When the fourth driving component 640 drives the frustum 641 to move upward, the third roller 631 can roll along the side wall of the frustum 641 and drive the rocker arm 630 to rotate relative to the riveting seat 620, thereby driving the actuating rod 660 to move horizontally toward the center of the riveting seat 620 and providing pressure to the spray bar workpiece.

[0054] In some embodiments, refer to Figure 1 The automatic spray bar assembly machine also includes a bending component 700, which is located on the outlet side of the assembly component 600. After assembly, the spray bar workpiece can be moved to the corresponding station of the bending component 700 under the action of the conveying component 100. The bending component 700 can bend the spray bar workpiece to change the outlet direction of the spray bar workpiece, making it more suitable for dental equipment so that it can be inserted into the patient's mouth for use.

[0055] Furthermore, refer to Figure 9The bending assembly 700 includes a sixth bracket 790, a fifth drive component 710, a sixth drive component 760, a third slider 720, a third track 730, two fourth sliders 740, a fourth track 750, a fifth track 780, and a bending block 770. The fifth drive component 710, the sixth drive component 760, the third track 730, the fourth track 750, and the fifth track 780 are all mounted on the sixth bracket 790. The third track 730 extends vertically and is located above the conveying assembly 100. The third slider 720 is slidably connected to the third track 730, and the output end of the fifth drive component 710 is connected to the third slider 720. Under the driving action of the fifth drive component 710, the third slider 720 can move vertically. The third slider 720 is provided with a guide groove that opens downwards. The fourth track 750 extends horizontally, and two fourth sliders 740 are slidably connected to the fourth track 750. Each fourth slider 740 is provided with a first roller 742. An elastic element (not shown in the figure) is provided between the two fourth sliders 740. The two sides of the guide groove along the extension direction of the fourth track 750 are inclined surfaces. The two inclined surfaces gradually approach each other from bottom to top. The two first rollers 742 contact the two inclined surfaces respectively. When the fifth drive component 710 drives the third slider 720 to move downward, the first rollers 742 can roll along the inclined surfaces, causing the two fourth sliders 740 to approach each other. When the fifth drive component 710 drives the third slider 720 to move upward, the fourth sliders 740 move away from each other and reset under the action of the elastic element. A clamping block 741 is provided at the lower end of the fourth slider 740. A clamping groove is provided on the side of the two clamping blocks 741 facing each other for clamping the outer tube 910. When the two fourth sliders 740 approach each other, the two clamping blocks 741 can clamp the outer tube 910 stably. The output end of the sixth driving component 760 is driven and connected to the bending block 770. The fifth track 780 is arranged parallel to the fourth track 750. The bending block 770 is slidably connected to the fifth track 780. Under the driving action of the sixth driving component 760, the bending block 770 can move along the fifth track 780. When the bending block 770 moves to the position of contacting the outer wall of the outer tube 910, the sixth driving component 760 continues to drive the bending block 770 to move in the original direction, which can bend the outer tube 910 and the inner tube 940 inside.

[0056] It is understandable that the clamping block 741 is positioned above the conveyor seat 110, and the bending block 770 is positioned above the clamping block 741. The bending angle of the spray bar workpiece can be adjusted by controlling the sliding stroke of the bending block 770 through the sixth drive component 760.

[0057] The fifth drive component 710 and the sixth drive component 760 can be cylinders, electric cylinders, etc., and are not specifically limited here.

[0058] In some embodiments, the bending block 770 is provided with a second roller 771 at one end that contacts the spray bar workpiece. In use, the second roller 771 contacts the side wall of the outer tube 910, reducing the friction between the bending block 770 and the outer wall of the outer tube 910 and preventing damage to the outer tube 910.

[0059] In some embodiments, refer to Figure 1 The automatic spray boom assembly machine also includes a second detection component 800, a first discharge component 810, and a second discharge component 820. The second detection component 800 is located on the outlet side of the assembly component 600, specifically on the outlet side of the bending component 700. It can detect whether the spray boom workpiece on the conveyor seat 110 is qualified. For example, it uses sensors in the second detection component 800 to detect whether the bending angle of the spray boom workpiece meets the standard, and whether any parts are missing. In some embodiments, a spray boom workpiece with no missing parts and meeting the bending angle standard is determined to be a qualified spray boom workpiece. The first discharge component 810 and the second discharge component 820 are respectively located on the outlet side of the second detection component 800. When the spray boom workpiece is qualified, the first discharge component 810 removes the spray boom workpiece from the conveyor seat 110 and collects it into the corresponding collection device. When the spray boom workpiece is determined to be unqualified, the second discharge component 820 removes the spray boom workpiece from the conveyor seat 110 and collects it into the waste disposal device. The second detection component 800, the first discharge component 810, and the second discharge component 820 complete the sorting and discharge of the spray bar workpieces, reducing the subsequent manual inspection and sorting processes and greatly improving production efficiency.

[0060] In some embodiments, if the first detection component 310 detects that the outer tube 910 is not connected to the first connector 920, that is, the first connector 920 is not feeding normally, the second discharge component 820 can also remove the workpiece on the conveyor seat 110 to the corresponding waste disposal device.

[0061] In some embodiments, the first discharge assembly 810 and the second discharge assembly 820 respectively include a ninth driving component, a tenth driving component, and a fourth pneumatic gripper. The output end of the ninth driving component is connected to the tenth driving component, and the output end of the tenth driving component is connected to the fourth pneumatic gripper. Under the driving action of the ninth driving component, the tenth driving component and the fourth pneumatic gripper can move on the horizontal plane and reach above the conveyor seat 110. The tenth driving component can drive the fourth pneumatic gripper to move in the vertical direction, and the fourth pneumatic gripper can grip the spray bar workpiece on the conveyor seat 110.

[0062] It is understood that the conveyor seat 110 in the conveying assembly 100 can pass under the first discharge assembly 810 and then under the second discharge assembly 820, or it can pass under the second discharge assembly 820 and then under the first discharge assembly 810; no specific limitation is made here. After the discharge is not completed, the conveyor seat 110 is empty and can move again under the action of the conveyor plate and pass under the first feeder 200.

[0063] In some embodiments, the automatic spray bar assembly machine further includes a worktable 900, and a first support 270, a second support 580, a third support 390, a fourth support 323, a fifth support 480, a sixth support 790, a seventh support, an eighth support, a ninth support 650, a first detection component 310, a second detection component 800, a first discharge component 810, a second discharge component 820, and a conveyor tray are all installed on the worktable 900.

[0064] Secondly, embodiments of the present invention provide a control method for an automatic spray boom assembly machine, which is applied to the automatic spray boom assembly machine as described in any of the embodiments of the first aspect, and can realize the automatic assembly of spray boom workpieces. The automatic spray boom assembly machine includes steps one, two, three, four, and five.

[0065] Step 1: Control the first feeder 200 to send the outer tube 910 onto the conveyor seat 110, and make the outer tube 910 extend in the vertical direction and be inserted into the positioning hole.

[0066] Step 2: When the conveyor seat 110 moves to the second feeder 300, control the second feeder 300 to install the first connector 920 onto the upper end of the outer tube 910.

[0067] Step 3: When the conveyor seat 110 moves to the third feeder 400, control the third feeder 400 to install the second connector 930 to the lower end of the outer tube 910.

[0068] Step 4: When the conveyor seat 110 moves to the fourth feeder 500, control the fourth feeder 500 to insert the inner tube 940 into the inner cavity of the outer tube 910.

[0069] Step 5: When the conveyor seat 110 moves to the assembly component 600, control the first pressing component 610 to press down the spray bar workpiece on the conveyor seat 110, so that the spray bar workpiece enters the riveting component, and control the riveting component to apply inward pressure to the outer periphery of the outer tube 910 so that the outer tube 910 is riveted to the inner tube 940.

[0070] In some embodiments, the automatic spray bar assembly machine further includes a punching assembly 320. After completing step two, the control method of the automatic spray bar assembly machine further includes controlling the third drive component 321 to start and causing the punch 322 to move downward to punch a hole in the first connector 920.

[0071] In some embodiments, the automatic spray bar assembly machine further includes a bending component 700. After completing step five, the control method of the automatic spray bar assembly machine further includes step six, controlling the bending component 700 to bend the spray bar workpiece. Specifically, the fifth driving component 710 is controlled to move, causing the third slider 720 to move downward and the two fourth sliders 740 to move towards each other. The spray bar workpiece is stably clamped by the two clamping blocks 741. The sixth driving component 760 is controlled to move, causing the bending block 770 to move towards the spray bar workpiece. After the bending block 770 contacts the spray bar workpiece, the sixth driving component 760 continues to drive the bending block 770 to move along the original direction, causing the spray bar workpiece to bend.

[0072] In some embodiments, the automatic spray bar assembly machine further includes a first detection component 310, a second detection component 800, a first discharge component 810, and a second discharge component 820. The first detection component 310 is disposed on the outlet side of the second feeder 300, and the second detection component 800 is disposed on the outlet side of the bending component 700. The control method of the automatic spray bar assembly machine further includes step seven, sorting and discharging. Specifically, based on the detection results of the first detection component 310 and the second detection component 800, the first discharge component 810 and the second discharge component 820 are controlled to operate, thereby realizing the automatic sorting and discharging of the spray bar workpieces.

[0073] This invention also provides a control device, including a memory, a processor, and a program stored in the memory and executable on the processor. When the program is executed by the processor, it implements the control method of the automatic spray bar assembly machine described above.

[0074] Taking the example of a processor and memory in a control device being connected via a bus, memory, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, memory may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. In some embodiments, memory may optionally include memory remotely located relative to the control processor, and these remote memories can be connected to the control device via a network.

[0075] The non-transient software program and instructions required to implement the control method of the above embodiments are stored in memory. When executed by the processor, the control method of the above embodiments is performed. For example, steps one to seven are executed.

[0076] The device embodiments described above are merely illustrative.
