Description

Technical Field

[0001] This utility model relates to the technical field of automated powder silo production equipment, specifically to an automatic installation device for powder silo pull rings. Background Technology

[0002] Electrophotographic imaging devices such as laser printers typically contain a toner cartridge, which can be removed from the printer. The toner hopper is the cavity inside the toner cartridge used to store toner.

[0003] After toner is filled, the filling port of the toner cartridge is usually sealed with a seal. To allow toner to be supplied smoothly during printing, the seal is removed. For easy removal of the seal, a pull ring is usually attached to the exposed end of the seal. Some existing toner cartridges, to ensure the pull ring does not interfere with subsequent assembly, insert the pull ring into a slot on the side of the toner cartridge before connecting the seal and the pull ring.

[0004] like Figure 1 As shown, the pull ring 11 has multiple insertion ends 111, which need to be inserted into different slots in the powder hopper 1, such as the first slot 12 and the second slot 13. This places high demands on alignment and insertion depth, making automation difficult. Therefore, the installation of the existing pull ring 11 is all done manually by inserting it into the powder hopper 1, which is labor-intensive and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide an automatic installation device for powder hopper pull rings, which solves the problem that the high difficulty of automated installation of existing pull rings leads to high efficiency and low cost of manual installation.

[0006] To achieve the purpose of this utility model, an automatic installation device for a powder hopper pull ring is provided, including a powder hopper conveying module, a pull ring conveying module, and a pull ring installation module. The powder hopper conveying module is used to move the powder hopper from the powder hopper loading position to the installation position. The pull ring conveying module is used to move the pull ring from the pull ring loading position to the pull ring installation module. The pull ring conveying module includes a first gripping part and a positioning seat. The first gripping part is used to move the pull ring to the positioning seat and is rotatable. The positioning seat is provided with a placement position and an outer peripheral positioning structure located on the outer periphery of the placement position. The outer peripheral positioning structure includes a positioning component, which includes a fixed part and a moving part arranged opposite to each other. The positioning surface of at least one of the fixed part and the moving part is set according to the outer peripheral contour of the pull ring. The pull ring installation module is provided with an installation position.

[0007] As can be seen from the above scheme, the positioning seat includes a placement position and an outer peripheral positioning structure. The first gripping part places the pull ring in the placement position, and the outer peripheral positioning structure adjusts the direction of the pull ring. The positioning component includes a fixed part and a moving part. The moving part is movable, and its movement generates a force on the pull ring, thereby adjusting the direction of the pull ring during placement to meet the installation requirements. At least one positioning surface of the fixed part and the moving part is set according to the outer peripheral contour of the pull ring, which can make it fit the pull ring more fully, resulting in a better positioning effect, avoiding stress concentration, and preventing damage to the pull ring. Through precise direction adjustment and positioning of the pull ring, the difficulty of automated installation of the pull ring and the difficulty of setting up the corresponding device are reduced. The entire process has a high degree of automation, high efficiency, and low labor costs.

[0008] A further option is that the peripheral positioning structure includes two sets of positioning components with mutually perpendicular positioning directions.

[0009] As can be seen from the above scheme, the two sets of mutually perpendicular positioning components enable positioning of the pull ring in multiple directions, making the positioning of the pull ring more accurate.

[0010] A further embodiment is that the two sets of positioning components include at least one of the following: one moving component is provided with a first contouring surface, the first contouring surface being a concave arc surface; one fixed component is provided with a second contouring surface, the second contouring surface being a plane; one moving component is provided with a third contouring surface, the third contouring surface being a plane; the two fixed components are respectively provided with a first fixed component contouring surface and a second fixed component contouring surface, both the first fixed component contouring surface and the second fixed component contouring surface being planes, and the first fixed component contouring surface and the second fixed component contouring surface being perpendicular to each other.

[0011] As can be seen from the above scheme, the different shapes of the fixed and moving parts are matched with the outer periphery of the pull ring, which can better position the pull ring in the required direction.

[0012] A further embodiment is that the pull ring mounting module includes a second gripping part, which is used to move the pull ring from the positioning seat to the mounting position; the second gripping part includes two claws arranged opposite each other, each claw having an inner side opposite to the other claw, the inner side being provided with a gripping groove, and the inner surface of the gripping groove being set as a fourth contour surface.

[0013] As can be seen from the above scheme, since the insertion part of the pull ring needs to be inserted into the powder hopper and cannot be used for gripping, it is necessary to consider the gripping ring part. However, the ring part made of plastic has a certain elastic deformation capability. This utility model chooses to use the two claws of the second gripping part to grip the ring part of the pull ring from both sides. The gripping groove is set with a contour surface. Since the upper and lower sides of the groove restrict the ring part, under this premise, pressure is applied from left to right. The groove also inhibits the bending deformation of the ring part in the vertical direction, so it can clamp the pull ring more stably with a greater gripping force.

[0014] A further option is that the positioning seat also has a clearance position on the outer periphery of the placement position, the first gripping part can be moved to the clearance position, and the second gripping part can be moved to the clearance position; the placement position includes a support surface, and the clearance position is recessed into the support surface; the clearance position is formed between the fixed part and the moving part.

[0015] As can be seen from the above scheme, the first gripping part can place the pull ring when it moves to the avoidance position, and the second gripping part can grab the pull ring when it moves to the avoidance position. The avoidance position can ensure that the pull ring is accurately placed on the positioning seat and accurately grabbed. The avoidance position is recessed into the support surface, which saves design space and makes the conveying line of the pull ring more reasonable.

[0016] A further option is that the installation location includes the powder hopper area and the pull ring area; the second gripper is also equipped with a limiting component, which is closer to the powder hopper area than the claw, and the limiting component faces the powder hopper area along the insertion and forward direction of the second gripper.

[0017] As can be seen from the above scheme, the limiting component restricts the forward distance of the pull ring. During the process of the second gripping part installing the pull ring into the slot of the powder hopper, when the limiting component and the powder hopper reach the contact state, the second gripping part will no longer continue to insert, so as to avoid the second gripping part from over-inserting and damaging the pull ring.

[0018] A further embodiment is that the installation location includes the powder hopper area and the pull ring area; the pull ring installation module also includes a push ring mechanism, which is located in the pull ring area. The push ring mechanism includes a push head and a push head drive unit. Under the drive of the push head drive unit, the push head can move closer to or away from the powder hopper area; the push head includes a protrusion for pushing the pull ring, and the protrusion direction of the protrusion is at an angle to the pushing direction of the push head; when the second gripping part is in the insertion position, the protrusion is coplanar with the two gripping grooves.

[0019] As can be seen from the above scheme, if the elastic ring is used as the pushing force point, it may damage the pull ring. The push ring mechanism uses the straight frame part in the middle of the pull ring as the pushing force point. The push ring mechanism plays a role in assisting the installation of the pull ring. When the second gripping part inserts the pull ring to a certain depth, the second gripping part is no longer suitable for inserting the pull ring. At this time, the push ring structure is used to push the pull ring further to insert it into place. This will not damage the pull ring. Moreover, when the push head pushes, the protruding part of the pull ring passes through the annular through hole of the pull ring. The force is applied to the straight frame of the pull ring rather than the outer arc frame, which is less likely to damage the pull ring.

[0020] A further option is to provide a hook at the tail of the protruding part that bends and extends toward the powder storage area.

[0021] As can be seen from the above scheme, the hook design prevents the pull ring from moving in the extension direction of the protrusion when the pusher pushes the pull ring.

[0022] A further embodiment is that the pull ring conveying module also includes a straight vibrator and a third gripping part. The straight vibrator is provided with a conveying channel, which includes a width limiting part. The width of the width limiting part is located between the minimum thickness and the maximum thickness of the pull ring, and the width limiting part is vertically continuous. The third gripping part is used to move the pull ring from the outlet of the conveying channel to the first gripping part. The third gripping part cooperates with the outlet of the conveying channel from below the width limiting part.

[0023] As can be seen from the above scheme, the setting of the width limiting part of the conveying channel allows the pull ring to be conveyed to the outlet in a specific vertical direction, which facilitates the subsequent clamping and installation of the pull ring. The third gripping part grabs the pull ring from below the conveying channel and then moves it to the first gripping part, making the conveying line design of the pull ring more reasonable and saving design space.

[0024] A further embodiment includes a powder hopper receiving module located downstream of the installation location. The powder hopper receiving module includes a receiving seat that can move along a first direction, and the receiving seat is provided with a fifth contoured surface. The powder hopper conveying module includes a feeding seat that can move along the first direction, and the feeding seat is provided with a sixth contoured surface. A powder hopper seat is provided at the installation location. The automatic installation equipment also includes at least two fourth gripping parts arranged along the first direction, and multiple fourth gripping parts can move along the first direction. The fourth gripping part closest to the feeding seat can reciprocate between the feeding seat and the powder hopper seat, and the fourth gripping part furthest from the feeding seat can move between the powder hopper seat and the receiving seat.

[0025] As can be seen from the above scheme, the feeding seat, mounting seat, and receiving seat are located on a straight line, making the powder hopper's conveying route simpler and eliminating the need for complex flow line design. The feeding seat, powder hopper seat, and receiving seat are all equipped with contoured surfaces, making the powder hopper's conveying process smoother and less prone to displacement. Multiple fourth gripping units can simultaneously realize the feeding and receiving of powder hoppers, improving the efficiency of automated installation. Attached Figure Description

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0042] See Figure 2 This embodiment provides an automatic installation device for a powder hopper pull ring, including a powder hopper conveying module 2, a pull ring conveying module 3, a pull ring installation module 4, a powder hopper receiving module 5, a fourth gripping part 6, and a frame 7. The powder hopper conveying module 2, the pull ring conveying module 3, the pull ring installation module 4, the powder hopper receiving module 5, and the fourth gripping part 6 are all mounted on the frame 7.

[0043] See Figures 2 to 5 The powder hopper conveying module 2 is used to move the powder hopper 1 from the powder hopper loading position to the installation position. The powder hopper conveying module 2 includes a loading seat 21, a first slide rail 22, a first drive component 27, a loading gripper 23, a loading drive component 24, a second slide rail 25, and a second drive component.

[0044] The first slide rail 22 extends along a first direction, which in this embodiment is the X-axis direction. The loading seat 21 is disposed on the first slide rail 22 and can reciprocate along the first slide rail 22 under the drive of the first driving component 27. The second slide rail 25 is disposed on one side of the first slide rail 22 along the Z-axis direction; specifically, in this embodiment, the second slide rail 25 is located above the first slide rail 22. The second slide rail 25 extends along the Y-axis direction, and the loading gripper 23 reciprocates along the second slide rail 25 under the drive of the second driving component 26. The loading driving component 24 includes a first driving unit 241 and a second driving unit 242. The first driving unit 241 drives the loading gripper 23 to move along the Z-axis direction, and the second driving unit 242 drives the loading gripper 23 to rotate in the plane formed by the X-axis and Y-axis directions.

[0045] The feeding seat 21 is provided with a first placement groove 211, and the inner surface of the first placement groove 211 is provided with a sixth contour surface, which is at least part of the outer periphery of the powder hopper 1.

[0046] The feeding gripper 23 picks up the powder hopper 1 from the powder hopper feeding position. In this embodiment, the powder hopper feeding position is located on the side of the second slide rail 25 away from the feeding seat 21. Driven by the second driving component 26, it moves along the second slide rail 25 in the Y-axis direction. At the same time, the second driving unit 242 drives the feeding gripper 23 to rotate in the plane formed by the X-axis and Y-axis directions until the outer periphery of the powder hopper 1 matches the sixth contour surface in the feeding seat 21. In this embodiment, this direction is the length direction of the powder hopper 1 coinciding with the Y-axis direction. When the feeding gripper 23 moves directly above the feeding seat 21, the first driving unit 241 drives the feeding gripper to move closer to the feeding seat 21 in the Z-axis direction, thereby placing the powder hopper 1 in the first placement groove 211 of the feeding seat 21. Subsequently, driven by the first driving component 27, the feeding seat 21 moves closer to the powder hopper seat 40 in the X-axis direction (i.e., the first direction).

[0047] The pull ring mounting module 4 is located downstream of the powder hopper conveying module 2. The pull ring mounting module 4 includes a powder hopper seat 40, which is positioned at the installation location. The powder hopper seat 40 is located on the side of the first slide rail 22 away from the second slide rail 25. Specifically, the feeding seat 21 and the powder hopper seat 40 are arranged along the X-axis direction (i.e., the first direction). The powder hopper seat 40 has a second placement groove 401, and the inner surface of the second placement groove 401 has a seventh contour surface, which mimics at least a portion of the outer periphery of the powder hopper 1.

[0048] The powder hopper receiving module 5 is located downstream of the installation position. The powder hopper receiving module 5 is used to move the powder hopper from the installation position to the unloading position. The powder hopper receiving module 5 includes a receiving seat 51, a third slide rail 52, a third drive component, a receiving gripper 53, a receiving drive component 54, a fourth slide rail 55, a sixth slide rail 56, and a conveyor belt 57.

[0049] The third slide rail 52 extends along the X-axis direction (i.e., the first direction). The receiving seat 51 is disposed on the third slide rail 52 and can reciprocate along the third slide rail 52 under the drive of the third driving component (not shown in the figure). The fourth slide rail 55 is disposed on one side of the third slide rail 52 in the Z-axis direction. Specifically, in this embodiment, the fourth slide rail 55 is disposed above the third slide rail 52. The fourth slide rail 55 extends along the X-axis direction, and the receiving gripper 53 reciprocates along the fourth slide rail 55 under the drive of the fourth driving component 56. The receiving driving component 54 includes a third driving unit 541 and a fourth driving unit 542. The third driving unit 541 drives the receiving gripper 53 to rotate in the plane formed by the X-axis and Y-axis directions, and the fourth driving unit 542 drives the receiving gripper 53 to move along the Z-axis direction.

[0050] The conveyor belt 57 is disposed downstream of the third slide rail 52. Specifically, in this embodiment, the conveyor belt 57 extends along the X-axis direction (i.e., the first direction). A portion of the fourth slide rail 55 is disposed above the third slide rail 52, and another portion of the fourth slide rail 55 is disposed above the conveyor belt.

[0051] The receiving seat 51 and the powder hopper seat 40 are arranged along the X-axis direction (i.e., the first direction). The receiving seat 51 is provided with a third placement groove 511, and the inner surface of the third placement groove 511 is provided with a fifth contour surface, which is a contour surface that imitates at least part of the outer periphery of the powder hopper 1.

[0052] The receiving seat 51 moves along the third slide rail 52 to the side close to the conveyor belt 57. The receiving gripper 53 moves along the Z-axis under the drive of the fourth drive unit 542 to grasp the powder hopper 1 on the receiving seat 51. Then, under the drive of the third drive unit 541, it rotates so that the length direction of the powder hopper 1 coincides with the X-axis direction. At the same time, under the drive of the fourth drive component 56, it moves along the fourth slide rail 55 in the X-axis direction. When it moves above the conveyor belt 57, the receiving gripper 53 moves along the Z-axis under the drive of the fourth drive unit 542 to place the powder hopper 1 on the conveyor belt 57. The powder hopper 1 continues to move with the conveyor belt 57 to the unloading position, which is set at the tail end of the conveyor belt 57.

[0053] In this embodiment, the automatic installation device further includes two fourth gripping parts 6 arranged along the X-axis direction (i.e., the first direction), and a fifth driving component 61 drives the fourth gripping parts to move along the Z-axis direction. Specifically, the two fourth gripping parts 6 are arranged on a moving plate 62 along the X-axis direction (i.e., the first direction). The moving plate is arranged on a fifth slide rail 63 extending along the X-axis direction (i.e., the first direction), and the moving plate 62 can move repeatedly along the fifth slide rail 63 under the drive of a sixth driving component 64. The fourth gripping part 6 on the side closer to the feeding seat 21 can reciprocate between the feeding seat 21 and the powder hopper seat 40, while the other fourth gripping part 6 on the side farther from the feeding seat can move between the powder hopper seat 40 and the receiving seat 51. The two fourth gripping parts 6 move synchronously and grip the powder hopper, thereby achieving simultaneous feeding and receiving, further improving installation efficiency.

[0054] See Figures 6 to 11 The pull ring conveying module 3 is used to transfer the pull ring 11 from the pull ring feeding position to the pull ring mounting module 4. The pull ring conveying module 3 includes a vibratory feeder 30, a linear vibrator 31, a third gripping part 32, a ring feeding drive unit 33, a blocking member 34, a blocking member drive unit 35, a first gripping part 36, a seventh drive component 37, a positioning seat 38, and a positioning seat drive unit 39.

[0055] The outlet end of the vibratory feeder 30 is connected to the linear vibrator 31, and the feeding position of the pull ring is set at the vibratory feeder 30. The linear vibrator 31 is provided with a conveying channel 311, which includes a width limiting part b. The width of the width limiting part b is located between the minimum and maximum thickness of the pull ring, and the width limiting part b is vertically continuous. In this embodiment, the conveying channel 311 is also vertically continuous, so that the pull ring 11 is conveyed to the outlet end of the conveying channel 311 in a specific vertical direction.

[0056] The third gripping part 32 is used to move the pull ring from the outlet of the conveying channel 311 to the first gripping part 36. Specifically, the third gripping part 32 moves along the X-axis under the drive of the ring delivery driving unit 33, moving the pull ring 11 at the outlet of the conveying channel 311 to the first gripping part 36. The third gripping part 32 and the outlet of the conveying channel 311 are engaged below the width limiting part b. Under the drive of the blocking member driving unit 35, the blocking member 34 can move between the release position and the blocking position. The blocking position is located in front of the outlet of the conveying channel 311, and the release position is when the blocking member 34 leaves the front of the outlet of the conveying channel 311, which will not affect the third gripping part 32's movement of the pull ring 11. In this embodiment, specifically, the blocking driving unit 35 drives the blocking member 34 to move along the Y-axis to block and release the outlet of the conveying channel 311.

[0057] The first gripping part 36 is positioned facing the exit of the conveyor channel 311, and under the drive of the seventh drive unit 37, the first gripping part 36 moves the pull ring 11 to the positioning seat 38. Specifically, see Figure 9The seventh driving component 37 includes a fifth driving unit 371, a sixth driving unit 372, and a seventh driving unit 373. The fifth driving unit 371 drives the first gripping part 36 to move along the X-axis, the sixth driving unit 372 drives the first gripping part 36 to move along the Z-axis, and the seventh driving unit 373 drives the sixth gripping part 36 to rotate, thereby rotating the vertically held pull ring 11 to a horizontal position and placing it on the positioning seat 38.

[0058] See Figure 10 The positioning seat 38 is provided with a placement position 381 and an outer peripheral positioning structure located on the outer periphery of the placement position. The outer peripheral positioning structure includes positioning components. The positioning components include a fixed member 382 and a movable member 383 disposed opposite to each other. The movable member 383 moves closer to or away from the corresponding fixed member 382 under the drive of the movable member driving unit 384. The positioning surface of at least one of the fixed member 382 and the movable member 383 is set according to the outer peripheral contour direction of the pull ring 11. In this embodiment, the outer peripheral positioning structure includes two sets of positioning components with mutually perpendicular positioning directions. In the positioning assembly with the positioning direction in the Y-axis direction, the moving member 383 is provided with a first contouring surface 3831, which is a concave arc surface, and the fixed member 382 is provided with a second contouring surface 3821, which is a plane. In the positioning assembly with the positioning direction in the X-axis direction, the moving member 383 is provided with a third contouring surface 3832, which is a plane, and the contouring surface 3822 of the fixed member 382 is also a plane. In this embodiment, the two fixed members are arranged perpendicularly to each other, and the corresponding first fixed member contouring surface (i.e., the second contouring surface 3821 with the positioning direction in the Y-axis direction) and the second fixed member contouring surface (i.e., the contouring surface 3822 of the fixed member with the positioning direction in the X-axis direction) are perpendicular to each other.

[0059] The positioning seat 38 also has a clearance position 385 on the outer periphery of the placement position 381. The first gripping part 36 can be moved to the clearance position 385 to place the pull ring 11. The pull ring mounting module 4 includes a second gripping part 41, and the second gripping part 42 can also be moved to the clearance position 385 to grip the pull ring 11. Specifically, the placement position 381 includes a support surface 3811, and the clearance position 385 is recessed in the support surface 3811. Preferably, the clearance position is formed between the fixed member 382 and the moving member 383.

[0060] The pull ring 11 is conveyed in a specific direction to the exit of the conveyor channel 311 by the vibrator 31. The third gripping part 32 grips the pull ring 11 at the exit and moves along the X-axis under the drive of the ring delivery drive unit 33. At the same time, the first gripping part 36 also moves closer to the third gripping part 32 under the drive of the seventh drive component 37. When the third gripping part 32 and the first gripping part 36 cooperate, the pull ring 11 is transferred. Subsequently, the first gripping part 36 moves and rotates under the drive of the seventh drive component 37 to place the pull ring 11 on the mounting base 38. The positioning base 38 includes a placement position 381 and an outer peripheral positioning structure. The outer peripheral positioning structure adjusts the direction of the pull ring 11 so that the direction of the pull ring 11 meets the installation requirements.

[0061] See Figures 11 to 15 The positioning seat 38 can move along the Y-axis under the drive of the positioning seat drive unit 39 to facilitate the transfer of the pull ring to the second gripping part 41. The pull ring mounting module 4 is used to install the pull ring 11 into the powder hopper 1. In addition to the powder hopper seat 40 and the second gripping part 41, the pull ring mounting module 4 also includes an eighth drive component 42, a push ring mechanism 43, an abutment mechanism 44, and a welding mechanism 45.

[0062] See Figure 12 The second gripping part 41 is used to move the pull ring from the positioning seat 38 to the installation position and perform preliminary installation. The second gripping part 41 includes two claw parts 411 arranged opposite to each other. Each claw part 411 has an inner side opposite to the other claw part 411, and a gripping groove 412 is provided on the inner side. The inner surface of the gripping groove is set as a fourth contour surface, which is set to imitate the outer peripheral contour of the pull ring 11.

[0063] The installation location includes a powder hopper area and a pull ring area. The powder hopper area is the area where the powder hopper 1 to be installed is located at the installation location, and the pull ring area is the area where the pull ring 11 to be installed is located at the installation location. The second gripping part 411 is also provided with a limiting member 413. The limiting member 413 is closer to the powder hopper area relative to the claw part 411. The limiting member is directly opposite the powder hopper area along the insertion direction of the second gripping part 41. In this embodiment, the insertion direction of the second gripping part 41 is the Y-axis direction. Specifically, when the second gripping part 41 inserts the insertion end 111 of the pull ring 11 into the mounting slots of the powder hopper 1, such as the first mounting slot 12 and the second mounting slot 13, at the installation location, the limiting member 413 is closer to the surface of the powder hopper 1 where the mounting slot is located.

[0064] Driven by the eighth drive unit 42, the second gripping part 41 moves the pull ring 11 from the mounting base 38 to the installation position for initial installation. Specifically, the eighth drive unit 42 includes an eighth drive unit 421 and a ninth drive unit 422. The eighth drive unit 421 drives the second gripping part 41 to move along the Y-axis, and the ninth drive unit 422 drives the second gripping part 41 to move along the Z-axis.

[0065] See Figure 13 and Figure 14 The push ring mechanism 43 is disposed in the pull ring area. The push ring mechanism 43 includes a push head 431 and a push head driving unit 432. Under the drive of the push head driving unit 432, the push head 431 can move closer to or away from the powder hopper area. In this embodiment, under the drive of the push head driving unit 432, the push head 431 can move along the Y-axis direction.

[0066] The pusher head 431 includes a protrusion 4311 for pushing the pull ring. The protrusion direction of the protrusion 4311 forms an angle with the pushing direction of the pusher head 431. Preferably, in this embodiment, the protrusion direction of the protrusion 4311 is the Z-axis direction. When the second gripping part 41 is in the insertion position, that is, when the second gripping part 41 is in the position where the insertion end 111 of the pull ring 11 can be inserted into the slot of the powder hopper 1, the protrusion 4311 is coplanar with the two gripping grooves 412. At this time, the pull ring 11 passes through the annular through hole 112 of the pull ring 11, and the force is applied to the straight frame 113 of the pull ring 11 rather than the external arc frame. The tail of the protrusion 4311 is provided with a hook 4312 that bends and extends toward the powder hopper area.

[0067] See Figure 15 Both the abutting mechanism 44 and the welding mechanism 45 are located above the installation position. Specifically, the abutting mechanism 44 is located above the powder hopper area, and the welding mechanism 45 is located above the pull ring area. The abutting mechanism 44 includes an abutting head 441 and an abutting drive unit 442. The abutting head 441 can move along the Z-axis direction under the drive of the abutting drive unit 442. The welding mechanism 45 includes a welding head 451 and a welding drive unit 452. The welding head 451 can move along the Z-axis direction under the drive of the welding drive unit 452.

[0068] The installation process involves the positioning seat 38 moving along the Y-axis while the second gripping part 41 moves closer to the positioning seat 38 under the drive of the eighth drive component 42. When the positioning seat 38 and the second gripping part 41 engage, the transfer of the pull ring 11 is completed. Subsequently, the second gripping part 41 moves closer to the installation position under the drive of the eighth drive component 42, initially inserting the insertion end 111 of the pull ring 11 into the slot of the powder hopper 1, while simultaneously positioning the protrusion 4311 of the push head 431 in the annular through hole 112 of the pull ring 11. At this time, the abutment 441 also moves downward along the Z-axis and abuts against the powder hopper 1 placed on the powder hopper seat 40, applying pressure to the powder hopper 1 to prevent displacement of the powder hopper 1 in the insertion direction during the installation of the pull ring 11. After the initial insertion is completed, the push head moves along the Y-axis to further push the pull ring 11 to achieve the final insertion, ensuring that the pull ring 11 is inserted in place without damaging it. After the pull ring 11 is inserted, the seal is located above the pull ring 11. To facilitate viewing the fit between the pull ring 11 and the powder hopper 1, the seal on the powder hopper 1 is not shown in this embodiment. However, the powder hopper being fed at the powder hopper loading position can actually be a powder hopper with a seal already installed. After the pull ring 11 is inserted, the welding head 451 moves downward along the Z-axis, causing the seal to abut against and be fixedly connected to the pull ring 11. The powder hopper 1, after installation and welding, can be received by the fourth gripping part 6 and the powder hopper receiving module 5. The entire process can be automated, resulting in high production efficiency and low labor costs.

[0069] It should be noted that the drive units in this embodiment are all drive types familiar to those skilled in the art, such as cylinder drives.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
