A pair of second cylinders 813 are symmetrically arranged on both sides of the first cylinder 811. A pair of buckle plates 814 are symmetrically arranged on the piston rod of the second cylinder 813.During assembly, the workpiece is positioned and supported by the carrier 13. The carrier then enters the frame 1 through the feed inlet 2. The loading mechanism 4 loads the carrier 13. The first clamping cylinder 804 is then driven downwards to the clamping position by the second lifting mechanism 805 at its top. The grippers at the bottom of the first clamping cylinder 804 clamp the carrier 13. The second lifting mechanism 805 then resets, lifting the carrier 13. At this point, the second translation mechanism 802 drives the first clamping cylinder 804 to move to the top of the moving platform of the first translation mechanism 6. The second lifting mechanism 805 then drives the first clamping cylinder 804 downwards again, placing the carrier 13 on the first... The translation mechanism 6 moves the carrier limiting mechanism at the top of the platform; at this time, the first translation mechanism 6 drives the carrier 13 to move to the bottom of the pressure block 812, and the third lifting mechanism 808 drives the second connecting plate 809 to move downward until the limiting pin 810 at the bottom of the second connecting plate 809 is inserted into the corresponding limiting hole on the surface of the carrier 13 to limit the carrier 13; at this time, the first cylinder 811 drives the pressure block 812 to move downward until it abuts against the workpiece, fixing the workpiece at the top of the carrier 13, and then the second cylinders 813 on both sides drive a pair of buckle plates 814 to move towards each other until they are engaged with the cover plates on the upper side of the nozzle mounting parts on both sides of the top of the workpiece. At this time, the third lifting mechanism 808 drives the buckle plates to move towards each other. 814 moves upward to remove the cover plate on top of the workpiece, exposing the nozzle mounting part; then the first translation mechanism 6 drives the carrier 13 to move to the bottom of the nozzle assembly mechanism 9, and the nozzle assembly mechanism 9 transports the carrier 13 to the positioning mechanism 12, and the positioning mechanism 12 positions the carrier 13. Then, the nozzle feeding mechanism 11 places the nozzle on the nozzle mounting part on top of the workpiece, and the nozzle assembly mechanism 9 installs the nozzle on both sides of the top of the workpiece; after the nozzle is installed, the nozzle assembly mechanism 9 transports the carrier 13 to the first translation mechanism 6, and the first translation mechanism 6 drives the carrier 13 to move again to the bottom of the pressure block 812. At this time, the cover plate disassembly and assembly mechanism 8... Repeat the above steps in reverse order, reinstalling the top cover plate of the workpiece on the upper side of the nozzle mounting parts on both sides of the top of the workpiece to protect the nozzles; then, the first translation mechanism 6 drives the carrier 13 to move to the bottom of the second clamping cylinder 806, and the second lifting mechanism 805 drives the jaws at the bottom of the second clamping cylinder 806 to clamp the carrier 13. The second translation mechanism 802 transports the carrier 13 to the top of the unloading flow line 5, so that the assembled workpiece flows out along the unloading flow line 5 along the outlet 3. Through the above steps, the top cover plate of the workpiece can be automatically disassembled and assembled during the assembly process, which facilitates the assembly of the nozzles, effectively improves the automation level of the equipment, and thus improves the assembly efficiency of the nozzles.

[0034] Please see Figure 5The loading mechanism 4 includes a first mounting frame 401, the bottom of which extends through the mounting plate to the lower side of the mounting plate. A first lifting mechanism 406 is provided on the side wall of the first mounting frame 401. A loading rack 402 is vertically fixed to the bottom of the mounting plate. A loading flow line 405 is horizontally arranged at the bottom of the loading rack 402. Several carriers 13 are detachably mounted on the top of the loading flow line 405. An adjusting frame 403 is detachably mounted on the outer side of the bottom of the loading rack 402. A barcode scanner 404 is detachably mounted on the top of the adjusting frame 403. During loading, the carriers 13 move along the loading flow line 405 to the lifting platform of the first lifting mechanism 406. The barcode scanner 404 can scan and register the information of the workpiece on the top of the carrier 13 during the movement of the carrier 13. After scanning, the first lifting mechanism 406 transports the carrier 13 to the top of the mounting plate, realizing automatic loading of the carriers 13 and the workpiece.

[0035] Please see Figure 9 The nozzle assembly mechanism 9 includes a third mounting bracket 901. A third translation mechanism 902 is provided on the top of the third mounting bracket 901. A third connecting plate 903 is fixedly connected to the moving platform of the third translation mechanism 902. A fourth lifting mechanism 904 is provided on the side wall of the third connecting plate 903. A fourth connecting plate 905 is fixedly connected to the lifting platform of the fourth lifting mechanism 904.

A pair of third cylinders 907 are symmetrically provided on the side wall of the fourth connecting plate 905. A pressure head 908 is fixedly connected to the piston rod of the third cylinder 907. When the carrier 13 moves to the bottom of the pressure head 908, it stops moving. At this time, the fourth lifting mechanism 904 drives the fourth connecting plate 905 to move downward until the locking pin 906 at the bottom of the fourth connecting plate 905 is inserted into the limiting hole on the surface of the carrier 13. The locking pin 906 is an expansion pin that expands when inserted into the carrier 13 to fix the carrier 13. Then the fourth lifting mechanism 904 resets and lifts the carrier 13. The third translation mechanism 902 drives the carrier 13 to move to the top of the positioning mechanism 12. After the carrier 13 is positioned, the nozzle is placed on the nozzle mounting part on the top of the workpiece by the nozzle feeding mechanism 11. Then the third cylinder 907 drives the pressure head 908 to move downward to press the nozzle and the workpiece together.

[0036] A first vision module 909 is provided on the side of the fourth lifting mechanism 904, and a second vision module 14 is provided on the lower part of the third translation mechanism 902 facing the positioning mechanism 12. The second vision module 14 is located at the bottom of the fourth connecting plate 905. During the process of limiting the position of the carrier 13, the first vision module 909 can provide visual guidance for the position of the carrier 13. When the carrier 13 is transported, it passes through the second vision module 14, which can detect the position of the carrier 13 to prevent the carrier 13 from tilting during assembly.

[0037] Please see Figure 11 The nozzle feeding mechanism 11 includes a fourth mounting frame 1101. A fourth translation mechanism 1102 is provided on the top of the fourth mounting frame 1101. A fifth connecting plate 1103 is fixedly connected to the moving platform of the fourth translation mechanism 1102. A fifth lifting mechanism 1104 is provided on the side wall of the fifth connecting plate 1103. A pair of third clamping cylinders 1105 are fixedly connected to the lifting platform of the fifth lifting mechanism 1104. A pair of limit blocks 1106 are fixedly connected to the piston rod of the third clamping cylinder 1105. A third vision module 1007 is provided on the side of the fifth lifting mechanism 1104. When the nozzle is being fed, the fifth lifting mechanism 1104 drives the third clamping cylinder 1105 to move downward until the limiting block 1106 at its bottom is inserted into the inner side of the nozzle at the corresponding position on the material tray to limit the nozzle. Then the fifth lifting mechanism 1104 resets and drives the nozzle to move upward to disengage from the material tray. Then the fourth translation mechanism 1102 drives the nozzle to move to the top of the workpiece nozzle mounting part of the positioning mechanism 12. Then the fifth lifting mechanism 1104 drives the third clamping cylinder 1105 to place the nozzle on the nozzle mounting part on the top of the workpiece. During placement, the third vision module 1007 can provide visual guidance for the nozzle feeding, so as to achieve precise automatic feeding of the nozzle.

[0038] Please see Figure 10 A tray feeding mechanism 10 is provided on the side of the nozzle feeding mechanism 11 away from the first translation mechanism 6. The tray feeding mechanism 10 includes a fifth translation mechanism 1001. Several hoppers 1002 are provided on the top of the fifth translation mechanism 1001. Tray picking cylinders 1003 are provided on both sides of the bottom of the hoppers 1002. A tray placement platform 1004 is fixedly connected to the moving platform of the fifth translation mechanism 1001. When feeding the nozzle, the tray at the bottom of the hopper 1002 can be placed on the tray placement platform 1004 by the tray picking cylinders 1003. Then, the tray placement platform 1004 is driven to move to the nozzle feeding station by the fifth translation mechanism 1001 to realize automatic feeding of the tray.

[0039] The positioning mechanism 12 includes a base 1201, a positioning cylinder 1202 is horizontally fixedly connected to the top of the base 1201, a positioning platform 1203 is fixedly connected to the piston rod of the positioning cylinder 1202, a number of positioning blocks 1205 are provided on the top of the positioning platform 1203, and a number of distance sensors 1204 are provided on the edge of the positioning platform 1203. During nozzle assembly, the carrier 13 is placed on top of the positioning table 1203 by the nozzle assembly mechanism 9. During placement, the positioning block 1205 limits the carrier 13, and the distance sensors 1204 on both sides can precisely adjust the position of the carrier 13 to facilitate positioning. After the carrier 13 is placed, the positioning cylinder 1202 drives the positioning table 1203 and the carrier 13 to move towards the nozzle feeding mechanism 11 until the carrier 13 stops at the nozzle unloading station. At this time, the nozzle feeding mechanism 11 places the nozzle on the nozzle mounting part on top of the workpiece. Then, the positioning cylinder 1202 resets, causing the carrier 13 to move to the nozzle pressing station, where the press head 908 presses the nozzle. Through the above steps, the carrier 13 and the nozzle can be precisely positioned during nozzle assembly, effectively improving the assembly accuracy of the nozzle.

[0040] The feeding flow line 405 and the unloading flow line 5 are arranged in parallel directions. The first translation mechanism 6 and the fifth translation mechanism 1001 are arranged in directions perpendicular to the feeding direction of the unloading flow line 5. The second translation mechanism 802, the third translation mechanism 902 and the fourth translation mechanism 1102 are all arranged in directions parallel to the feeding direction of the unloading flow line 5.

[0041] The first translation mechanism 6 has a temporary storage flow line 7 on its side, and the conveying direction of the temporary storage flow line 7 is perpendicular to the conveying direction of the unloading flow line 5. By setting up the temporary storage flow line 7, the carrier 13 can be buffered in the event of equipment failure, thus avoiding congestion.

[0042] Working Principle: During assembly, the workpiece is positioned and supported by the carrier 13. The carrier then enters the frame 1 along the feed inlet 2. The loading mechanism 4 loads the carrier 13. During loading, the carrier 13 moves along the loading flow line 405 to the lifting platform of the first lifting mechanism 406. The barcode scanner 404 scans and registers the information of the workpiece on top of the carrier 13 during its movement. After scanning, the first lifting mechanism 406 transports the carrier 13 to the top of the mounting plate, achieving automatic loading of the carrier 13 and the workpiece. Then, the second lifting mechanism 805 at the top of the first clamping cylinder 804 drives the first clamping cylinder 804 to move downward to the clamping position. The grippers at the bottom of the first clamping cylinder 804 clamp the carrier 13. Then, the second lifting mechanism 805 resets, lifting the carrier 13. At this time, the second translation mechanism 802 drives the first clamping cylinder 804 to move to the first translation machine. The first lifting mechanism 805 drives the first clamping cylinder 804 to move downward again, placing the carrier 13 on the carrier limiting mechanism at the top of the first translation mechanism 6. At this time, the carrier 13 is driven to move to the bottom of the pressure block 812 by the first translation mechanism 6, and the second connecting plate 809 is driven to move downward by the third lifting mechanism 808 until the limiting pin 810 at the bottom of the second connecting plate 809 is inserted into the corresponding limiting hole on the surface of the carrier 13 to limit the carrier 13. At this time, the first cylinder 811 drives the pressure block 812 to move downward to abut against the workpiece, fixing the workpiece at the top of the carrier 13. Then, the second cylinders 813 on both sides drive a pair of buckle plates 814 to move towards each other until they are fastened to the cover plates on the upper side of the nozzle mounting parts on both sides of the top of the workpiece. At this time, the third lifting mechanism 808 drives the buckle plates 814 to move upward, removing the cover plates on the top of the workpiece, so that the nozzle mounting parts are exposed.

[0043] Then, the first translation mechanism 6 drives the carrier 13 to move to the bottom of the nozzle assembly mechanism 9. When the carrier 13 moves to the bottom of the pressure head 908, it stops moving. At this time, the fourth lifting mechanism 904 drives the fourth connecting plate 905 to move downward until the locking pin 906 at the bottom of the fourth connecting plate 905 is inserted into the limiting hole on the surface of the carrier 13. The locking pin 906 is an expansion pin, which expands when inserted into the carrier 13 to fix the carrier 13. Then, the fourth lifting mechanism 904 resets and lifts the carrier 13. The third translation mechanism 902 drives the carrier 13 to move to the top of the positioning mechanism 12. During nozzle assembly, the nozzle... Assembly mechanism 9 places carrier 13 on top of positioning table 1203. During placement, positioning block 1205 limits the carrier 13, while distance sensors 1204 on both sides allow for precise adjustment of the carrier 13's position, facilitating its positioning. After carrier 13 is placed, positioning cylinder 1202 drives positioning table 1203 and carrier 13 towards nozzle feeding mechanism 11 until carrier 13 reaches nozzle unloading position. At this point, nozzle feeding mechanism 11 places nozzle on the nozzle mounting part on top of workpiece, and then positioning cylinder 1202 resets. This causes the carrier 13 to move to the nozzle pressing station, where the nozzle is pressed in place by the press head 908. Through these steps, precise positioning of the carrier 13 and the nozzle can be achieved during nozzle assembly, effectively improving the nozzle assembly accuracy. After the carrier 13 is positioned, the nozzle is placed on the nozzle mounting part at the top of the workpiece by the nozzle feeding mechanism 11. During nozzle feeding, the fifth lifting mechanism 1104 drives the third clamping cylinder 1105 downwards until the bottom limiting block 1106 inserts into the inner side of the nozzle at the corresponding position on the material tray, limiting the nozzle. Then, the fifth lifting mechanism 1104 resets, driving the nozzle towards... The upper movement detaches from the material tray, and then the fourth translation mechanism 1102 drives the nozzle to move to the top of the workpiece nozzle mounting part of the positioning mechanism 12. Then the fifth lifting mechanism 1104 drives the third clamping cylinder 1105 to place the nozzle on the top of the workpiece nozzle mounting part. During placement, the third vision module 1007 can provide visual guidance for the nozzle loading, realizing precise automatic loading of the nozzle. After the nozzle is placed, the positioning cylinder 1202 resets, causing the carrier 13 to move to the nozzle pressing station. Then the third cylinder 907 drives the pressing head 908 to move downward, pressing the nozzle and the workpiece together.

[0044] After the nozzles are installed, the carrier 13 is transported to the first translation mechanism 6 by the nozzle assembly mechanism 9. The first translation mechanism 6 drives the carrier 13 to move to the bottom of the pressure block 812 again. At this time, the cover plate disassembly and assembly mechanism 8 repeats the above steps in reverse, and reinstalls the cover plate on the top of the workpiece on the upper side of the nozzle mounting parts on both sides of the top of the workpiece to protect the nozzles. Then, the first translation mechanism 6 drives the carrier 13 to move to the bottom of the second clamping cylinder 806. The second lifting mechanism 805 drives the jaws at the bottom of the second clamping cylinder 806 to clamp the carrier 13. The second translation mechanism 802 transports the carrier 13 to the top of the unloading flow line 5, so that the assembled workpiece flows out along the unloading flow line 5 and the discharge port 3.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
