At the manual repair welding station 5, the corner brace 107, bottom reinforcing plate 110 and other small parts that need to be welded are welded to the express cabinet. At the erection station 6, the welded express cabinet is erected.

[0020] In some embodiments, the outer casing welding station 1 includes a first welding robot 7, a rotating base 8, a rotating table 9, a support ring 10, a support frame 11, support wheels 12, a rotation drive assembly, and a loading adjustment assembly. The rotating table 9 is rotatably mounted on the rotating base 8, and the support ring 10 is coaxially fixedly mounted on the lower surface of the rotating table 9. The rotating base 8 is evenly provided with at least three sets of support frames 11, and support wheels 12 are rotatably mounted on the support frames 11 for pressing against the support ring 10. The rotation drive assembly is fixedly mounted on the rotating base 8 and is used to drive the rotating table 9 to rotate. Two sets of loading adjustment assemblies are symmetrically arranged on the rotating table 9, and the loading adjustment assemblies cooperate with the first welding robot 7. The first welding robot 7 is existing technology. The rotating base 8 is used to mount the rotating table 9 and the support frames 11. The support wheels 12 on the support frames 11 are used to press against the support ring 10 on the rotating table 9 to prevent instability of the rotating table 9 during rotation. The function of the rotation drive assembly is to drive the rotating table 9 to rotate on the rotating base 8. Two sets of loading adjustment components are provided on the rotary table 9. One set of loading adjustment components welds the back plate 100, top plate 102 and two side plates 101 together under the action of the first welding robot 7. The other set of loading adjustment components fixes the back plate 100, top plate 102 and two side plates 101 together after the shell semi-finished product is unloaded.

[0021] In some embodiments, the rotary drive assembly includes a rack 13, a transmission gear 14, a rotary drive member 15, a rack seat 16, a limiting block 17, a locking seat 18, a locking drive member 19, and a locking block 20. The rack seat 16 is fixedly mounted on the rotary base 8. The rack 13 is slidably mounted on the rack seat 16 and meshes with the transmission gear 14. The transmission gear 14 is coaxially fixedly mounted on the rotary table 9. The rotary drive member 15 is fixedly mounted on the rotary base 8 and is used to drive the rack 13 to move.

The rotating base 8 has two mating rack seats 16 for mounting rack rods 13. A transmission gear 14 meshes with the rack rods 13 between the two rack seats 16. The rotation drive 15 is a pneumatic or hydraulic cylinder, as used in the prior art. The cylinder body of the rotation drive 15 is fixed to the rotating base 8, and the piston rod of the rotation drive 15 is fixedly connected to one end of the rack rod 13 via a connecting plate. The rotating base 8 also has two locking seats 18. A limiting block 17 is fixed to the rotating table 9 and rotates with it. The rotating table 9 rotates 180 degrees and contacts the locking seats 18, then reverses 180 degrees and contacts the locking seats 18 again. Under the action of the two locking seats 18, the rotating table 9 can only rotate 180 degrees. The locking drive 19 is a tilting cylinder, as used in the prior art. The locking drive 19 drives the locking block 20 to rotate, which presses the limiting block 17 onto the locking seats 18, thus preventing the rotating table 9 from rotating.

The loading slide rails 22 and the insertion rod 28 are arranged parallel to each other. The loading slide plate 23 is slidably mounted on the loading slide rail 22 by a slider. Different models of express cabinets can be manufactured by adjusting the distance between the two loading slide plates 23. The loading slide plate 23 is fixed to the insertion rod 28 by a pin 29 to prevent the loading slide plate 23 from moving. The back plate 100 is placed directly on the loading rack 21. Vertical limit rods 24, vertical stabilizer rods 25, T-shaped rods 26 and stabilizer blocks 27 are fixedly installed on the inner end of the loading rack 21 and the loading slide plate 23. The vertical limit rods 24 limit the outer sides of the top plate 102 and the two side plates 101. The vertical stabilizer rods 25, T-shaped rods 26 and stabilizer blocks 27 work together to limit the inner sides of the top plate 102 and the two side plates 101.

[0023] In some embodiments, the inner plate welding station 2 includes an inner plate support 32, an inner plate welding frame 33, an inner plate conveying component 34, an inner plate welding adjusting component 35, and an inner plate welding head 36. The inner plate conveying component 34 is fixedly mounted on the inner plate support 32, the inner plate welding adjusting component 35 is fixedly mounted on the middle part of the inner plate support 32 via the inner plate welding frame 33, and the inner plate welding head 36 is fixedly mounted on the output part of the inner plate welding adjusting component 35. The inner plate support 32 is used to mount the inner plate welding frame 33 and the inner plate conveying component 34. The inner plate conveying component 34 is a prior art device and pushes the inner vertical plate 103 to move. The inner plate welding frame 33 is used to mount the prior art inner plate welding adjusting component 35. The inner plate welding adjusting component 35 drives the inner plate welding head 36 to move up and down. The function of the inner plate welding head 36 is to weld the inner horizontal plate 104 onto the inner vertical plate 103.

[0024] In some embodiments, the full welding station 4 includes a second welding robot 37, a transport frame 38, short-section tracks 39, a traction component, and a positioning component. At least two sets of cooperating short-section tracks 39 are provided on both sides of the transport frame 38. The transport frame 38 is equipped with a traction component and a positioning component that cooperate with the short-section tracks 39. The second welding robot 37 cooperates with the transport frame 38. The transport frame 38 is used to install components such as the traction component and the positioning component. The second welding robot 37 is existing technology and is used to weld the outer shell semi-finished product, the inner panel semi-finished product, the partition plate 105, and the base plate 106 together. The traction component moves the express cabinet on the transport frame 38, and the positioning component accurately positions the express cabinet, facilitating precise welding by the second welding robot 37.

[0025] In some embodiments, the traction assembly includes a long-distance traction drive 40, a rotating shaft 41, a short-distance traction drive 42, a moving frame 43, a pressing drive 65, and a friction block 64. The rotating shaft 41 is rotatably mounted on the transport frame 38. The long-distance traction drive 40 is fixedly mounted on the transport frame 38 and is used to drive the rotating shaft 41 to rotate. The moving frame 43 is slidably mounted on the short section track 39. The short-distance traction drive 42 is fixedly mounted on the moving frame 43 and is used to drive the moving frame 43 to move. Each moving frame 43 is provided with a pressing drive 65, and the friction block 64 is fixedly mounted on the output part of the pressing drive 65. Both the long-distance traction drive 40 and the short-distance traction drive 42 are motors in the prior art. The long-distance traction drive 40 drives the rotating shaft 41 to rotate via a chain component in the prior art. Multiple sets of rotating shafts 41 are equally spaced on the transport frame 38, and adjacent rotating shafts 41 are also transmitted through a chain component in the prior art. The rotation of the rotating shaft 41 can drive the express cabinet forward. A rack is installed on the transport frame 38, and a gear that meshes with the rack is installed on the output shaft of the short-distance traction drive 42. Through the meshing of the rack and gear, the moving frame 43 can be moved on the short-section track 39. The pressing drive 65 is a cylinder in the prior art. The pressing drive 65 is symmetrically arranged at both ends of the moving frame 43. The two pressing drive 65 on both sides drive the friction blocks 64 to move. The two friction blocks 64 press against the two side plates 101 of the express cabinet, thereby driving the entire express cabinet to move on the transport frame 38. The moving frame 43 can stop at a precise position when moving the express cabinet. In this production line, the entire transport is divided into multiple transport segments. Each transport segment is transported either by the long-distance traction drive 40 and the rotating shaft 41, or by the short-distance traction drive 42 and the moving frame 43. The two methods are not used at the same time, but positioning components are set at the welding positions where they need to stop.

[0026] In some embodiments, a vertical adjustment component 44 is fixedly mounted on the movable frame 43, a horizontal adjustment component 45 is fixedly mounted on the output of the vertical adjustment component 44, a vertical fine-tuning component 46 is fixedly mounted on the output of the horizontal adjustment component 45, and a welding component 47 is mounted on the vertical fine-tuning component 46. The vertical adjustment component 44, horizontal adjustment component 45, vertical fine-tuning component 46, and welding component 47 are all prior art. The vertical adjustment component 44 drives the welding component 47 to move a long distance vertically, the vertical fine-tuning component 46 drives the welding component 47 to move a short distance vertically, and the horizontal adjustment component 45 drives the welding component 47 to move towards both ends of the movable frame 43. The welding component 47 is used to weld the upper reinforcing plate 108 to the top plate 102 and the lower reinforcing plate 109 to the bottom plate 106.

[0027] In some embodiments, the positioning assembly includes a side positioning frame 48, a front positioning frame 49, a rear positioning frame 50, a side positioning drive 51, a side positioning block 52, a rear positioning drive 53, a rear positioning block 54, a front positioning drive 55, a front positioning block 56, and a front positioning guide rod 57. Side positioning frames 48 are fixedly mounted on both sides of the transport frame 38. A side positioning drive 51 is fixedly mounted on the side positioning frame 48, and a side positioning block 52 is mounted on the output portion of the side positioning drive 51.

The side positioning drive 51 and the front positioning drive 55 are both pneumatic or hydraulic cylinders in the prior art, while the rear positioning drive 53 is a tilting cylinder in the prior art. Side positioning frames 48 are fixedly installed on the sides of the transport frame 38. The side positioning frames 48 are used to mount the side positioning drive 51. The side positioning drive 51 drives the side positioning block 52 to move, and the side positioning block 52 abuts against the side plate 101, thus positioning both sides of the express cabinet. The front positioning frame 49 and the rear positioning frame 50 can be fixed to the ground or to the transport frame 38. The rear positioning frame 50 is used to mount the rear positioning drive 53. The rear positioning block 54 on the output part of the rear positioning drive 53 abuts against the top plate 102 and positions the end of the top plate 102. The front positioning frame 49 is used to mount the front positioning drive 55 and the front positioning guide rod 57. The front positioning block 56 is mounted on the positioning drive 55 and the front positioning guide rod 57 to position the bottom plate 106. Since the express delivery locker needs to pass through the transport rack 38, the side positioning block 52, the rear positioning block 54 and the front positioning block 56 need to be designed to be telescopic to prevent the express delivery locker from being blocked and unable to be transported.

[0028] In some embodiments, the vertical mounting station 6 includes a release bracket 58, a vertical bracket 59, a vertical rotating frame 60, a vertical driving component 61, and a release control component 62. The output end of the release bracket 58 engages with the input end of the vertical bracket 59. The output end of the release bracket 58 is equipped with the release control component 62. The vertical rotating frame 60 is rotatably mounted on the output end of the vertical bracket 59 via a hinge shaft 63. The two ends of the vertical driving component 61 are hinged to the vertical bracket 59 and the vertical rotating frame 60, respectively. Both the release bracket 58 and the vertical bracket 59 are inclined. Under gravity, the parcel locker can move from the release bracket 58 onto the vertical bracket 59. The release control component 62 is existing technology; the parcel locker can only move from the release bracket 58 onto the vertical bracket 59 after the release control component 62 is released and relaxed. The upright driving component 61 is a hydraulic cylinder in the prior art. Under the action of the upright driving component 61, the upright rotating frame 60 is pushed to rotate around the hinge shaft 63, so that the upright rotating frame 60 is erected and its lower end contacts the ground. After the upright express cabinet is transported away, the upright driving component 61 is controlled to make the upright rotating frame 60 return to its initial position.
