[0049] Please also refer to Figures 1 to 8 The handle loading device provided by the present invention is now described. The handle loading device comprises a handle loading machine 30, a handle transfer mechanism 40, and a handle moving platform 50. The handle loading machine 30 has a lifting mechanism, which is used to adjust the handle to a preset posture (see Figure 5 ) is lifted to a preset height, the handle moving platform 50 is located in front of the handle loading machine 30, and is used to drive the handle to move in the front and rear directions, and the handle transfer mechanism 40 is used to transfer the handle on the lifting mechanism to the handle moving platform 50, and drive the handle to rotate during the transfer process to ensure that the raised structure of the handle is set forward.

[0050] It should be noted that the “front” in this application is Figure 5 From the directions marked in the figure, it is not difficult to understand that "back" is the opposite of "front".

[0051] The specific working process of the handle loading device provided in this embodiment is: the handle loading machine 30 lifts a handle to a preset height through the jacking mechanism, the handle transfer mechanism 40 grabs the handle on the jacking mechanism and ensures that the raised structure on the handle is set forward by rotation, and the handle transfer mechanism 40 transports the adjusted handle to the handle moving platform 50, and the handle moving platform 50 grabs the handle and moves it to the outside of the plastic barrel, which can then be assembled with the plastic barrel.

[0052] Compared with the existing technology, the lifting mechanism in the handle loading device of the utility model can ensure the consistency of the posture of the handle, and the handle is rotated by the handle transfer mechanism 40 to switch the direction of the raised structure on the handle, thereby ensuring the assembly accuracy of the plastic barrel and the handle. The posture of the handle is automatically adjusted without manual intervention, reducing labor costs and improving assembly efficiency.

[0053] In some embodiments, a specific embodiment of the handle loading machine 30 can be as follows: Figures 5 to 8 The structure shown. Figures 5 to 8 The lifting loading machine 30 also includes a storage rack 31, a third lifting cylinder 32, a first pushing block 33, a fourth lifting cylinder 34 and a second pushing block 35. The storage rack 31 has a supporting plate 311 that gradually tilts downward from back to front. The lowest side of the supporting plate 311 is provided with a first through slot 312 and two second through slots 313. The two second through slots 313 are symmetrically located on opposite sides of the first through slot 312. The third lifting cylinder 32 is provided in the storage rack 31 and is located below the supporting plate 311. The first pushing block 33 is fixed to the third lifting cylinder 34. The piston rod of the lowering cylinder 32, the first pusher block 33 corresponds to the first through slot 312 up and down, the top of the first pusher block 33 has a supporting slot 331 and a guide slope 332 located on the rear side of the supporting slot 331, and the guide slope 332 gradually tilts downward from front to back; the fourth lifting cylinder 34 is arranged in the storage rack 31 and is located below the supporting plate 311; the second pusher block 35 is fixed to the piston rod of the fourth lifting cylinder 34, the second pusher block 35 corresponds to the second through slot 313 up and down, and the top surface of the second pusher block 35 gradually tilts upward from front to back;

[0054] The third lifting cylinder 32 and the first pushing block 33 form a lifting mechanism.

[0055] It should be noted that the width of the support groove 331 is equal to the thickness of the handle, thus ensuring that only one handle enters the support groove 331 and that the handles are positioned in the same position within the support groove 331. Side panels 314 are provided on opposite sides of the support plate 311, with the distance between the two side panels 314 being equal to the length of the handle. The first pusher block 33 is located in the middle of the support plate 311, thereby ensuring that the support groove 331 supports the middle of the handle and preventing the handle from tilting and falling out of the support groove 331. To facilitate observation of the operation of the third and fourth lifting cylinders 32 and 34, observation windows 315 are provided on the side panels 314.

[0056] After the lifting of the lifting plate 311, the lifting device 312 is lifted and the lifting of the lifting plate 311 is lifted, and the lifting of the lifting plate 311 is lifted and the lifting of the lifting plate 311 is lifted.

[0057] This structure can ensure that the raised structure of the handle is facing toward or away from the assembly platform 10 when the handle is in the supporting groove 331, thereby facilitating subsequent rotation adjustment and assembly of the handle and ensuring rapid assembly of the handle and the plastic bucket.

[0058] As an improved embodiment of the handle loading machine 30, not shown in the figure, the front side wall of the storage rack 31 is also provided with a pushing cylinder, which is used to push the handle on the lowest side of the support plate 311 backward, so as to avoid the piled-up handles at this position from twisting with each other and affecting the loading of a single handle.

[0059] In some embodiments, an improved embodiment of the handle loading machine 30 can be adopted as follows Figure 6 The structure shown. Figure 6 A vibrator 318 is provided at the bottom of the supporting plate 311. By providing the vibrator 318 at the bottom of the supporting plate 311, it is convenient to promote the handle on the supporting plate 311 to slide toward the lowest side of the supporting plate 311 through vibration, thereby ensuring that there is a handle on the top of the jacking mechanism.

[0060] In some embodiments, a specific embodiment of the handle transfer mechanism 40 can be as follows: Figures 5 to 8 The structure shown. Figures 5 to 8, a photoelectric identifier 36 is provided on the top of the handle loading machine 30, and the handle transfer mechanism 40 includes a fourth linear module 41, a second rotary motor 42, a fifth lifting cylinder 45, a third fixed platform 43 and two second clamps 44. The fourth linear module 41 is arranged above the handle moving platform 50, and the fourth linear module 41 is parallel to the running track of the handle moving platform 50; the second rotary motor 42 is slidably connected to the fourth linear module 41, and the output shaft of the second rotary motor 42 is vertically arranged. The second rotary motor 42 is communicatively connected to the photoelectric identifier 36; the fifth lifting cylinder 45 is fixedly connected to the output shaft of the second rotary motor 42; the third fixed platform 43 is fixedly connected to the piston rod of the fifth lifting cylinder 45; the two second clamps 44 are fixedly connected to the third fixed platform 43, and the two second clamps 44 are used to grab the two ends of the handle;

[0061] When the photoelectric identifier 36 identifies that the raised structure on the handle is facing the assembly platform 10, the second rotary motor 42 does not rotate; when the photoelectric identifier 36 identifies that the raised structure on the handle is facing away from the assembly platform 10, the second rotary motor 42 rotates 180°.

[0062] When the first pushing block 33 lifts the handle to a preset height, the photoelectric identifier 36 identifies the direction of the raised structure on the handle, and the second clamping jaws 44 are located directly above the handle. The two second clamping jaws 44 grab the two ends of the handle and take the handle out of the supporting groove 331. The second rotating motor 42 rotates 180° or does not rotate according to the signal of the photoelectric identifier 36. Then the second clamping jaws 44 move to directly above the handle moving platform 50. After the handle moving platform 50 clamps the handle, the second clamping jaws 44 releases and continues to grab the next handle.

[0063] This structure can automatically identify the raised structure of the handle and adjust the direction of the raised structure on the handle through the second rotary motor 42, replacing manual labor. The adjustment process is rapid and the assembly efficiency is improved.

[0064] Optionally, the second clamping jaw 44 is a pneumatic clamping jaw.

[0065] In some embodiments, an improved embodiment of the handle loading machine 30 can be adopted as follows Figures 5 to 7 See the structure shown. Figures 5 to 7 The storage rack 31 is further provided with a guide groove 316 on the side facing the assembly platform 10. The guide groove 316 extends in the up-down direction, and the first pusher block 33 is slidably fitted in the guide groove 316. The first pusher block 33 can be provided with a guide structure that matches the shape of the guide groove 316. During the up-down sliding process of the first pusher block 33, the guide structure slides within the guide groove 316, which can ensure that the width of the supporting groove 331 on the first pusher block 33 is constant, thereby preventing the distance between the first pusher block 33 and the side wall of the storage rack 31 from increasing during the up-down sliding process, thereby preventing multiple handles from entering the supporting groove 331.

[0066] Specifically, a guide plate 317 is provided on the side of the storage rack 31 facing the assembly platform 10, and a guide groove 316 is located on the guide plate 317. A fourth telescopic cylinder 37 is also provided horizontally at the top of the guide plate 317, as well as a blocking block 38 fixed to the piston rod of the fourth telescopic cylinder 37. When the first pusher 33 drives the handle upward, the fourth telescopic cylinder 37 controls the blocking block 38 to extend and position itself directly above the supporting groove 331. This limits the rising height of the first pusher 33 and also presses the handle into the supporting groove 331 to maintain its posture when the handle has not yet fully fallen into the supporting groove 331. When the handle transfer mechanism 40 grabs the handle, the fourth telescopic cylinder 37 controls the blocking block 38 to retract, ensuring that the second gripper 44 can smoothly remove the handle.

[0067] In some embodiments, an improved embodiment of the handle loading machine 30 can be adopted as follows Figures 5 to 7 The structure shown. Figures 5 to 7 Each of the two side panels 314 is equipped with a centering mechanism 39. This mechanism comprises a centering cylinder 391 and a centering block 392 secured to the piston rod of the centering cylinder 391. The two centering blocks 392 are positioned opposite each other to enable relative or opposite movement. These blocks 392 push the ends of the handle so that the support groove 331 supports the center of the handle. The centering mechanism 39 allows the handle to be adjusted left and right (perpendicular to the front-to-back and vertical directions) to ensure that the raised structures at both ends align with the mounting holes after subsequent bending, improving assembly accuracy.

[0068] In some embodiments, an improved embodiment of the handle loading machine 30 can be adopted as follows Figures 5 to 7 The structure shown. Figures 5 to 7 A handle identifier 310 is provided on the side of the storage rack 31 facing the assembly platform 10. The handle identifier 310 is in communication with the fifth lifting cylinder 45. The handle identifier 310 is mounted on one side of the guide plate 317. When the first pusher block 33 drives the handle to rise to a preset height, the middle portion of the handle is located within the support slot 331, with both ends extending outside the support slot 331. The handle identifier 310 is used to identify the portion of the handle outside the support slot 331. When a handle is identified, the fifth lifting cylinder 45 activates and drives the second clamping claw 44 to grab the handle. When the handle identifier 310 detects that there is no handle, the fifth lifting cylinder 45 does not activate, thereby reducing the number of times the fifth lifting cylinder 45 runs idle.

[0069] In some embodiments, a specific implementation of the handle moving platform 50 can be as follows: Figure 3 The structure shown. Figure 3The handle moving platform 50 includes a fifth linear module 51 and a third clamping jaw 52. The fifth linear module 51 is connected between the handle loading machine 30 and the assembly platform 10, and the third clamping jaw 52 is slidably connected to the fifth linear module 51. After the second clamping jaw 44 grabs the handle and places it into the third clamping jaw 52, ​​the third clamping jaw 52 moves on the fifth linear module 51, driving the handle toward the plastic bucket until the handle is installed.

[0070] Optionally, the third clamping jaw 52 is a pneumatic clamping jaw.

[0071] Based on the same inventive concept, the present invention also provides a plastic bucket handle assembly device. The device comprises an assembly platform 10, a gripping device 20, the handle loading device, an identification unit 60, and an assembly mechanism 70. The gripping device 20 comprises a first running track 21, a first gripping mechanism 22, and a second gripping mechanism 23. The first running track 21 is located above the assembly platform 10. The first gripping mechanism 22 and the second gripping mechanism 23 are slidably connected to the first running track 21. The first gripping mechanism 22 is used to place the plastic bucket on the assembly platform 10 and drive the plastic bucket on the assembly platform 10 to rotate. The second gripping mechanism 23 is used to grab the plastic bucket and remove it from the assembly platform 10. The identification unit 60 is disposed on both sides of the assembly platform 10 and is in communication with the first gripping mechanism 22. The identification unit 60 is configured to stop the first gripping mechanism 22 from rotating the plastic bucket upon identifying a mounting hole on the plastic bucket. The assembly mechanism 70 is disposed on both sides of the assembly platform 10 and is configured to push the raised structure on the handle into the mounting hole of the plastic bucket.

[0072] It should be noted that the handle moving platform 50 is located between the assembly platform 10 and the handle loading machine 30. The assembly platform 10 is located in front of the handle loading machine 30. Therefore, it is necessary to ensure that the raised structure of the handle is set forward.

[0073] The first grasping mechanism 22 grasps the plastic barrel onto the assembly platform 10, and identifies the position of the mounting hole on the plastic barrel through the identification unit 60. If the mounting hole does not correspond to the identification unit 60, the first grasping mechanism 22 will drive the plastic barrel on the assembly platform 10 to rotate until the identification unit 60 identifies the mounting hole. During this process, the handle loading device synchronously performs the handle loading. The handle moving platform 50 grasps the handle and moves it to the outside of the assembly platform 10. At this time, the height of the raised structure on the handle is equal to the height of the mounting hole of the plastic barrel. Then, the assembly mechanism 70 bends the handle and pushes the raised structure on the handle into the mounting hole of the plastic barrel. The second grasping mechanism 23 grabs the assembled plastic barrel on the assembly platform 10.

[0074] Compared with the prior art, the plastic bucket handle assembly equipment of the present invention can automatically rotate the posture of the plastic bucket through the first gripping mechanism 22 in the gripping mechanism, and the lifting mechanism in the handle loading device can ensure the consistency of the posture of the handle, and the handle is rotated through the handle transfer mechanism 40 to switch the direction of the raised structure on the handle, thereby ensuring the assembly accuracy of the plastic bucket and the handle, and the posture of the plastic bucket and the handle are automatically adjusted without manual intervention, thereby reducing labor costs and improving assembly efficiency.

[0075] In order to facilitate the transportation of plastic barrels before and after assembly, a loading conveyor belt 80 and a unloading conveyor belt 81 can be set on opposite sides of the assembly platform 10 respectively. The loading conveyor belt 80 is used to transport the plastic barrels before assembly, and the barrel mouth of the plastic barrel faces downward; the unloading conveyor belt 81 is used to transport the assembled plastic barrels, and the barrel mouth of the plastic barrel still faces downward.

[0076] It should be noted that the loading conveyor belt 80 and the unloading conveyor belt 81 are located below the two ends of the first running track 21, so that the first grabbing mechanism 22 can move above the loading conveyor belt 80 and the assembly platform 10, and the second grabbing mechanism 23 can move above the assembly platform 10 and the unloading conveyor belt 81 and the assembly platform 10.

[0077] Specifically, in order to save space, the loading conveyor belt 80 and the unloading conveyor belt 81 can be arranged in parallel.

[0078] In some embodiments, a specific embodiment of the above-mentioned feeding conveyor belt 80 can be as follows Figure 1 See the structure shown. Figure 1 Guide rods 82 and limit plates 83 are provided on top of the feeding conveyor 80. The guide rods 82 are located on opposite sides of the feeding conveyor 80 and are parallel to the running path of the feeding conveyor 80. The limit plates 83 are located at the ends of the feeding conveyor 80. During transportation on the feeding conveyor 80, the plastic barrel is always located between the two guide rods 82. When the plastic barrel moves directly below the first running track 21, it contacts the limit plates 83 and stops moving. At this time, the plastic barrel can be grasped by the first grasping mechanism 22. This structure can limit the plastic barrel, improve the alignment accuracy between the first grasping mechanism 22 and the plastic barrel, and facilitate grasping by the first grasping mechanism 22.

[0079] In addition, a position sensor can be set on the feeding conveyor belt 80. When the plastic barrel moves to contact the limit plate 83, the position sensor recognizes that there is a plastic barrel here and transmits a signal to the first grabbing mechanism 22. The first grabbing mechanism 22 starts to grab the plastic barrel on the feeding conveyor belt 80.

[0080] Similarly, the unloading conveyor belt 81 may also be provided with a guide rod 82 and a limiting plate 83 of the same structure.

[0081] In some embodiments, a specific implementation of the identification unit 60 may be as follows: Figures 1 to 4 The structure shown. Figures 1 to 4 The identification unit 60 includes a first lifting cylinder 61, a first fixed platform 62, a first telescopic cylinder 63 and an identification module. The first lifting cylinder 61 is arranged on both sides of the assembly platform 10: the first fixed platform 62 is fixed to the piston rod of the first lifting cylinder 61; the first telescopic cylinder 63 is fixed to the first fixed platform 62; the identification module is fixed to the piston rod of the first telescopic cylinder 63; the first telescopic cylinder 63 is used to drive the identification module to move in the direction close to or away from the assembly platform 10.

[0082] In this embodiment, since both the identification unit 60 and the assembly mechanism 70 need to operate on the mounting hole of the plastic barrel, by setting the first lifting cylinder 61, the identification module can be moved downward to avoid the assembly mechanism 70 when the assembly mechanism 70 is used, and the assembly mechanism 70 will be moved away when it is not used. At this time, the identification module moves upward to the same height as the mounting hole on the plastic barrel; during the identification process, the first telescopic cylinder 63 drives the identification unit 60 close to the mounting hole of the plastic barrel to perform the normal identification process.

[0083] In some embodiments, a specific implementation of the above-mentioned recognition module can be as follows: Figures 1 to 4 The structure shown. Figures 1 to 4 The identification module includes a second fixed platform 64, a first fixed block 65, a test needle 66, a spring 67 and a distance sensor 68. The second fixed platform 64 is fixed to the piston rod of the first telescopic cylinder 63; the first fixed block 65 is fixed to the first fixed platform 62; the test needle 66 is slidably connected to the first fixed block 65; the spring 67 is sleeved on the outer circumference of the test needle 66, and the spring 67 has a pre-tightening force that enables the test needle 66 to be inserted into the mounting hole on the plastic barrel; the distance sensor 68 is arranged on the side of the test needle 66 facing away from the assembly platform 10;

[0084] When the test needle 66 is inserted into the mounting hole of the plastic barrel, the distance sensor 68 detects that the distance between the test needle 66 and the test needle 66 changes, and transmits a signal to the first gripping mechanism 22, and the first gripping mechanism 22 stops rotating the plastic barrel.

[0085] After the plastic barrel is placed on the assembly platform 10, the first gripping mechanism 22 has not released the plastic barrel. At this time, the identification module rises to a position at the same height as the mounting hole on the plastic barrel. The first telescopic cylinder 63 drives the first fixed platform 62 to move a preset distance close to the assembly platform 10. If the test needle 66 does not correspond to the mounting hole of the plastic barrel, the test needle 66 abuts against the outer extension of the barrel mouth of the plastic barrel. The test needle 66 squeezes the spring 67, and the distance measured by the distance sensor 68 is x1. The first gripping mechanism 22 drives the plastic barrel to rotate. When the test needle 66 corresponds to the mounting hole, the spring 67 rebounds so that the test needle 66 extends into the mounting hole. At this time, the distance between the distance sensor 68 and the test needle 66 is x2, and x2 is greater than x1. At this time, it is judged that the rotation is in place, and the first gripping mechanism 22 stops rotating the plastic barrel and releases the plastic barrel.

[0086] When the plastic barrel is placed on the assembly platform 10, the first telescopic cylinder 63 drives the first fixed platform 62 to move a preset distance closer to the assembly platform 10. At this time, if the test needle 66 is just inserted into the mounting hole of the plastic barrel, the distance measuring sensor 68 directly measures the distance between it and the test needle 66 as x2, then the first grasping mechanism 22 does not rotate the plastic barrel and directly releases it.

[0087] By measuring the state of the plastic barrel through the device, the position of the installation hole of the plastic barrel can be quickly determined, and then the posture of the plastic barrel can be adjusted in cooperation with the first grasping mechanism 22 to improve the accuracy of subsequent assembly.

[0088] In some embodiments, an improved embodiment of the assembly platform 10 may be as follows: Figures 1 to 4 The structure shown. Figures 1 to 4 Assembly platform 10 is provided with positioning blocks 11, which are designed to fit against the inner wall of the plastic bucket. Once placed on assembly platform 10, the plastic bucket fits over the outer periphery of positioning blocks 11, ensuring that the plastic bucket is centered on assembly platform 10. This ensures a consistent spacing between the plastic bucket and the two test pins 66 on either side, as well as between the plastic bucket and the extrusion head 721 of assembly mechanism 70. This ensures that the raised structures on both ends of the handle fit into the mounting holes during assembly. Furthermore, both the test pins 66 and assembly mechanism 70 apply a certain amount of pressure to the plastic bucket during operation. Positioning blocks 11 provide support against the inner wall of the plastic bucket, preventing deformation of the plastic bucket during assembly.

[0089] Optionally, the shape of the positioning block 11 can be annular or circular, and the diameter of the annular or circular positioning block 11 is equal to the diameter of the inner circumference of the plastic barrel; or the shape of the positioning block 11 is a quadrilateral, in which case there are two positioning blocks 11, and the two positioning blocks 11 correspond to the positions of the two test needles 66. Similarly, during assembly, the two positioning blocks 11 also correspond to the positions of the two extrusion heads 721 in the assembly mechanism 70.

[0090] In some embodiments, a specific embodiment of the assembly mechanism 70 can be as follows: Figures 3 and 4 See the structure shown. Figures 3 and 4 The assembly mechanism 70 includes a bending component 71 and an assembly component 72. The bending components 71 are respectively arranged on opposite sides of the handle moving platform 50. The bending component 71 includes a bending rod 711. The bending rod 711 is used to push the end of the handle so that the raised structure on the handle fits the plastic bucket; the assembly components 72 are respectively arranged on opposite sides of the assembly platform 10. The assembly component 72 includes an extrusion head 721. The extrusion head 721 is used to push the raised structure on the handle into the mounting hole of the plastic bucket.

[0091] Since the handle is straight in its natural state, but becomes curved after being installed on the plastic bucket, in order to ensure installation, when the handle moving platform 50 drives the handle to move to the outer periphery of the plastic bucket, the bending rod 711 on the bending component 71 pushes the end of the handle to bend toward the plastic bucket until the protruding structure on the handle corresponds to the installation hole. At this time, the assembly component 72 is started, and the extrusion head 721 pushes the protruding structure into the installation hole to complete the assembly. After the assembly is completed, the bending component 71, the assembly component 72, and the handle moving platform 50 all return to their initial positions.

[0092] In some embodiments, a specific implementation of the bending assembly 71 can be as follows: Figure 3 See the structure shown. Figure 3 The bending assembly 71 also includes a first linear module 712 and a second lifting cylinder 713. The first linear module 712 is parallel to the trajectory of the handle moving platform 50. The second lifting cylinder 713 is slidably connected to the first linear module 712. The bending rod 711 is fixed to the piston rod of the second lifting cylinder 713. The second lifting cylinder 713 can drive the bending rod 711 downward, thereby avoiding the height of the handle when the handle moving platform 50 drives the handle. After the handle moves to the outer periphery of the plastic barrel, the bending rod 711 rises and moves on the first linear module 712 to push the end of the handle to bend.

[0093] In some embodiments, an improved embodiment of the assembly platform 10 may be as follows: Figure 4 See the structure shown. Figure 4 , limit platforms 12 are provided on opposite sides of the top of the assembly platform 10, and the bottom surface of the bending rod 711 is flush with the top surface of the limit platform 12; wherein, the plastic bucket is placed between the two limit platforms 12, and the handle is placed on the top of the two limit platforms 12.

[0094] By setting the limit platform 12, the height of the handle can be limited to ensure that it corresponds to the mounting hole on the plastic bucket, and the operating height of the bending rod 711 can also be limited. The handle can only be pushed when the bending rod 711 rises to the top surface of the limit platform 12, otherwise it will abut against the side wall of the limit platform 12 and cannot move.

[0095] In some embodiments, a specific embodiment of the assembly component 72 can be as follows: Figure 4 The structure shown. Figure 4 The assembly component 72 also includes a second telescopic cylinder 722 and a third telescopic cylinder 723. The piston rod of the second telescopic cylinder 722 is parallel to the running path of the handle moving platform 50. The third telescopic cylinder 723 is fixed to the piston rod of the second telescopic cylinder 722. The extrusion head 721 is fixed to the piston rod of the third telescopic cylinder 723 and is used to move closer to or away from the plastic barrel.

[0096] When the recognition unit 60 is working, the second telescopic cylinder 722 drives the extrusion head 721 away from the top of the recognition unit 60. At this time, the recognition unit 60 can work normally. After the recognition unit 60 finishes working, the recognition module descends, and the second telescopic cylinder 722 drives the third telescopic cylinder 723 to move until the extrusion head 721 corresponds to the mounting hole position on the plastic barrel. At this time, the third telescopic cylinder 723 is directly above the recognition module. The third telescopic cylinder 723 drives the extrusion head 721 to move closer to the plastic barrel until the protruding structure is pushed into the mounting hole.

[0097] In some embodiments, a specific implementation of the first gripping mechanism 22 can be as follows: Figures 1 to 3 The structure shown. Figures 1 to 3 The first grasping mechanism 22 includes a second linear module 221, a first rotary motor 222 and a first clamp 223. The second linear module 221 extends in the up and down directions, and the second linear module 221 is slidably connected to the first running track 21; the first rotary motor 222 is slidably connected to the second linear module 221, and the output shaft of the first rotary motor 222 is arranged up and down; the first clamp 223 is fixed to the output shaft of the first rotary motor 222, and the first clamp 223 is used to grasp the plastic bucket.

[0098] Optionally, the first clamp 223 is a pneumatic clamp, and the second linear module 221 moves on the first running track 21, so that the first clamp 223 switches above the loading conveyor 80 and the assembly platform 10, and the first rotary motor 222 moves on the second linear module 221 to realize the lifting and lowering of the first clamp 223. Then, the first clamp 223 can grab the plastic barrel and also drive the plastic barrel to rotate when the first rotary motor 222 is started. The first clamp 223 has better gripping stability for the plastic barrel and is not easy to slip during the rotation process.

[0099] In some embodiments, a specific implementation of the second gripping mechanism 23 can be as follows: Figures 1 to 3 The structure shown. Figures 1 to 3The second gripping mechanism 23 includes a third linear module 231 and a suction cup module 232. The third linear module 231 extends vertically and is slidably connected to the first operating rail 21. The suction cup module 232 is slidably connected to the third linear module 231 and is used to absorb the plastic bucket. The third linear module 231 moves on the first operating rail 21 to grab the plastic bucket from the assembly platform 10 and place it on the unloading conveyor 81. The suction cup module 232 moves on the third linear module 231 to move the plastic bucket up and down. Since the second gripping mechanism 23 does not need to rotate the plastic bucket, the suction cup module 232 can quickly grasp and release the plastic bucket, speeding up the work process.
