Description

Technical Field

[0002] The silicone sheath used for tattoo needles (usually integrated into disposable tattoo needle cups or cartridges) is an indispensable component of modern tattoo supplies. It forms an integrated structure with the needle / cartridge, rather than a separate part.

[0003] In automated production, the precise and rapid assembly of the molded silicone sheath into the plastic cartridge and the pre-assembly with the needle bar is a critical and complex process. This process requires highly precise mechanical linkage to ensure accurate positioning and stable posture of the sheath within the cartridge, and to guarantee a precise fit with the needle bar.

[0004] However, existing automated equipment often struggles to stably mount the silicone leather kit onto the outer wall of the push rod during assembly, leading to assembly failures or incomplete placement and consequently, low product yield.

Therefore, they should not be construed as limitations on this utility model.

[0059] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0060] Reference example Figures 1 to 13An automatic assembly device for silicone leather cases includes a rotating disk 1, on which a plurality of material trays 11 are evenly distributed along the circumference; the material trays 11 are provided with at least one material trough 12 and at least one limiting block 13; a back cover material conveying mechanism 2 for clamping and conveying the back cover to the material trough 12; a back cover orientation calibration mechanism 3 for calibrating the position of the back cover by rotation; a push rod material conveying and positioning mechanism 4 for clamping the push rod and calibrating the position of the push rod by rotation, and then clamping the push rod and inserting it into the limiting block 13; a first pressing mechanism 5 for pressing the push rod into the limiting block 13; a silicone leather case conveying mechanism 6; and a silicone leather case conveyor. Structure 6 includes a silicone sleeve material conveying mechanism 61, a spreading mechanism 62, and a clamping and holding mechanism 63. The silicone sleeve material conveying mechanism 61 is used to convey silicone sleeve components, the clamping and holding mechanism 63 is used to clamp and transport the silicone sleeve components to the spreading mechanism 62, the spreading mechanism 62 is used to spread the silicone sleeve, and the clamping and holding mechanism 63 is used to hold the spread silicone sleeve and fit it onto the push rod; assembly mechanism 7 is used to clamp and convey the assembly of the push rod and silicone sleeve to the rear cover; second pressing mechanism 8 is used to apply downward pressure to the assembly so that it is engaged with the rear cover; and discharge mechanism 9 is used to convey the assembled product into the storage box.

[0061] It is worth mentioning that a first top block 14 is provided on one side of the material trough 12, a second top block 15 is provided on the material tray 11, a spring 16 is provided between the second top block 15 and the first top block 14, and a cavity 131 for accommodating the push rod is provided on the limiting block 13.

[0062] Spring 16 creates a clamping force between the second top block 15 and the first top block 14 to hold the rear cover in place, preventing the rear cover from detaching during the rotation of the rotating disk 1. Furthermore, when the rear cover is not positioned between the first top block 14 and the second top block 15, a certain distance is maintained between them, facilitating the rear cover's insertion between the two components. The groove 441 matches the shape on the push rod, according to the attached... Figure 2 As shown in the exploded view above the material trough 12, the materials from top to bottom are silicone sleeve, push rod, and back cover.

[0063] It is worth mentioning that the back cover material conveying mechanism 2 and the silicone sleeve material conveying mechanism 61 include a vibrating base 21. The vibrating base 21 is provided with at least one guide rail 22 for accommodating the back cover or silicone sleeve material. A horizontal blocking block 23 is provided on one side of the discharge end of the guide rail 22. The blocking block 23 is provided with a receiving groove 231. A blocking telescopic cylinder 24 is provided below the guide rail 22 and is connected and fixed to the blocking block 23. A back cover bracket 25 is provided on one side of the vibrating base 21. The back cover bracket 25 is provided with a back cover slider 26 that can move left and right. A back cover telescopic cylinder is provided at one end of the back cover bracket 25 and is connected and fixed to the back cover slider 26. The back cover slider 26 is provided with a back cover clamping cylinder 27 that corresponds to the guide rail 22 and can be raised and lowered. The back cover slider 26 is provided with a back cover lifting cylinder 28 and is connected to the back cover clamping cylinder 27.

[0064] The vibrating base 21 continuously conveys the back cover and silicone sleeve materials to the front end of the guide rail 22. When the sensor above the guide rail 22 senses that the material has entered the receiving groove 231, the piston rod of the blocking telescopic cylinder 24 retracts, causing the receiving groove 231 to be misaligned with the guide rail 22. The blocking block 23 not only prevents the subsequent material from continuing to move forward, but also puts the receiving groove 231 in a position that can be clamped by the back cover clamping cylinder 27.

[0065] It is worth mentioning that the rear cover orientation calibration mechanism 3 includes a liftable calibration slider 31 and a calibration lifting cylinder 32 mounted thereon. The calibration lifting cylinder 32 is connected and fixed to the calibration slider 31. The calibration slider 31 is provided with an extension 311, the extension 311 is provided with a gear 33, the gear 33 is provided with a calibration rod 34, and each face of the entrance of the calibration rod 34 is provided with an inclined part 341. The calibration slider 31 is provided with calibration telescopic cylinders 35 on both sides, and the calibration telescopic cylinders 35 are provided with racks 36 and mesh with the gears 33.

[0066] To address the mismatch between the randomly oriented rear cover holes on the material tray 11 and the transmission part of the push rod, the aforementioned mechanism utilizes the rotation and descent of the calibration rod 34 to gradually influence the calibration of the rear cover holes through its tilting part 341. Since the size of the tilting part 341 is smaller than the size of the rear cover holes, the calibration process is ensured to proceed smoothly, ultimately achieving the orientation calibration of the rear cover holes.

[0067] It is worth mentioning that the push rod assembly mechanism 7 includes a push rod support platform 41, a push rod bracket 42 disposed above it, and a vibratory feeder 432. The push rod support platform 41 is provided with a push rod transport plate 43 that can move back and forth. The push rod transport plate 43 is provided with at least one chamber 431 for accommodating the push rod. The vibratory feeder 432 is provided with a curved conveying pipe 433 and is disposed above the chamber 431.

A push rod slider 46 that can move left and right is provided. A push rod telescopic cylinder 47 is provided on one side of the push rod bracket 42. The push rod slider 46 is provided with a first push rod lifting cylinder 48 and a second push rod lifting cylinder 49. The first push rod lifting cylinder 48 is provided with a first push rod clamping cylinder 481 that can be lifted and lowered, which is used to convey the push rod material to the groove 441 of the servo motor 45. The second push rod lifting cylinder 49 is provided with a second push rod clamping cylinder 491 that can be lifted and lowered, and a third push rod clamping cylinder 492. The second push rod clamping cylinder 491 is used to convey the calibrated push rod to the groove 441 of the storage block 44.

[0068] The push rod includes a push column, one end of which is provided with a transmission part. The push rod transport plate 43 moves back and forth to continuously transport the push rod material to the first push rod clamping cylinder 481. The chamber 431 prevents the push rod from detaching during the movement. In response to the problem that the transmission part with random orientation on the cavity 131 does not match the hole position of the back cover, the push rod material is transported to the groove 441. As the rod part of the push rod enters the groove 441 first, the servo motor 45 gradually rotates to make the shape of the groove 441 match the shape of the transmission part. When the two coincide, the transmission part falls into the groove 441, and finally the orientation of the push rod is calibrated.

[0069] It is worth mentioning that the first pressing mechanism 5 includes a first pressing bracket 51, the first pressing bracket 51 is provided with a first pressing lifting cylinder 52, the first pressing lifting cylinder 52 is provided with a first pressing block 53, and is located above the limiting block 13.

The holding member 637 is provided with a clearance groove 6371 that avoids the spreading part 6231.

[0072] It is worth mentioning that the assembly mechanism 7 includes an assembly bracket 71, which is provided with a first assembly slider 72 that can move back and forth.

A discharge telescopic cylinder 94 is provided at one end of the support frame 92 and is connected and fixed to the discharge slider 93. The discharge slider 93 is provided with a first clamping cylinder 96 that can move up and down and is located above the discharge slide 91. A discharge lifting cylinder 95 is provided above the discharge slider 93 and is connected to the first clamping cylinder 96.

[0075] The working principle of this utility model is described as follows:

[0076] Once all the mechanisms have completed their respective tasks and operations, the turntable 1 will rotate and transfer the material tray 11 from the previous station to the next station, thereby continuously outputting qualified products.

[0077] This is the first process. The rear cover telescopic cylinder pushes the rear cover clamping cylinder 27 to position it above the receiving groove 231. The rear cover lifting cylinder 28 pushes the rear cover clamping cylinder 27 down, so that the rear cover clamping cylinder 27 clamps the rear cover in the receiving groove 231. Then the rear cover telescopic cylinder resets, so that the rear cover clamping cylinder 27 is above the material groove 12. The rear cover lifting cylinder 28 lowers the rear cover clamping cylinder 27 and inserts the rear cover into the material groove 12. Then all cylinders reset.

[0078] This is the second process. As the calibration lifting cylinder 32 gradually descends, the calibration rod 34 gradually penetrates into the hole in the back cover. At the same time, the calibration telescopic cylinder 35 pushes the rack 36 to move, thereby driving the gear 33 and the calibration rod 34 to rotate synchronously and calibrate the orientation of the hole in the back cover. After the calibration is completed, each cylinder is reset, so that the calibration rod 34 is higher than the back cover.

[0079] This is the third process. When the chamber 431 moves below the conveying pipe 433, the vibrating plate 432 vibrates and displaces the push rod into the chamber 431. Then, the push rod transport plate 43 moves the chamber 431 containing the push rod to the position to be clamped by the first push rod clamping cylinder 481. The push rod extension cylinder 47 pushes the first push rod clamping cylinder 481 above the chamber 431, the second push rod clamping cylinder 491 above the groove 441 of the servo motor 45, and the third push rod clamping cylinder 492 above the groove 441 of the storage block 44. As the first push rod lifting cylinder 48 pushes the first push rod clamping cylinder 481 down, the first push rod clamping cylinder 481 clamps the push rod material. At the same time, the second push rod lifting cylinder 49 pushes the second push rod... The rod clamping cylinder 491 and the third push rod clamping cylinder 492 descend to clamp the push rod after it has been calibrated. Then the first push rod lifting cylinder 48 and the second push rod lifting cylinder 49 reset. The push rod extension cylinder 47 pushes the push rod slider 46. Then the first push rod lifting cylinder 48 and the second push rod lifting cylinder 49 descend. The first push rod clamping cylinder 481 puts the push rod material into the groove 441 of the servo motor 45. The second push rod clamping cylinder 491 puts the calibrated push rod into the storage block 44. The third push rod clamping cylinder 492 inserts the push rod into the cavity 131. Then each cylinder resets. The servo motor 45 calibrates the position of the push rod. After the next push rod clamping cylinder moves above it, the position of the push rod has been calibrated.

[0080] This is the fourth process. The first pressing lifting cylinder 52 pushes the first pressing block 53 down and pushes the push rod that has not fully entered the cavity 131 into it, and then resets it.

[0081] This is the fifth step. The telescopic cylinder 633 pushes the first holding cylinder 635 to move above the receiving groove 231, and the second holding cylinder 636 moves above the base 621. As the holding lifting cylinder 634 descends, the first holding cylinder 635 clamps the silicone sleeve material, and the second holding cylinder 636 lowers the holding part 637 and enters the expanded silicone sleeve. The expanding cylinder 622 then resets, so that the silicone sleeve is tightly attached to the outer wall of the holding part 637. Then the holding lifting cylinder 634 resets, and the telescopic cylinder 633 pushes the first holding cylinder 635 to move above the base 621. The second holding cylinder 636 moves above the push rod of the material tray 11. The holding lifting cylinder 634 descends, so that the silicone sleeve is fitted into the outer wall of the expanded part 6231 and the outer wall of the push rod. Finally, all cylinders reset, completing the assembly of the assembly.

[0082] This is the sixth process. A spring 16 is installed between the expansion block 623 and the base 621 to ensure that the expansion part 6231 is tightly abutted against each other. After the expansion block 623 moves away from the axis of the base 621, the spring 16 drives the expansion block 623 to reset when it needs to be reset. When the push rod 6221 rises, the second inclined surface 6222 moves along the first inclined surface 6232, causing the expansion block 623 to gradually move away from the axis of the base 621, thereby expanding the diameter of the silicone sleeve. After the retainer 637 enters the expanded sleeve, the push rod 6221 descends, the spring 16 releases energy, the expansion part 6231 resets, and the silicone sleeve... The energy is released and tightly adhered to the retainer 637; through the mutual linkage of the above components, rapid and accurate positioning and assembly are achieved, effectively avoiding the problem of incomplete assembly, thereby significantly improving product assembly efficiency. The above structure has the advantages of simple structure and few linkage steps, overcoming the defects of existing automated equipment such as complex structure, high operation precision requirements, easy failure and high maintenance cost. This device can complete the process steps of opening, clamping and fitting without the cooperation of too many parts, effectively reducing the failure rate, reducing maintenance costs, improving production efficiency, and thus effectively reducing the manufacturing cost of tattoo needles.

[0083] This is the seventh process. The assembly telescopic cylinder 73 pushes the first assembly slider 72 forward, so that the assembly clamping cylinder 76 is above the assembly. After the servo motor 45 runs, it drives the lead screw 75 to rotate and drives the second assembly slider 74 to move downward. At this time, the gripper of the assembly clamping cylinder 76 is in the open state. After the gripper is on both sides of the assembly, the assembly clamping cylinder 76 applies clamping force to the assembly. The lead screw 75 rotates and drives the second assembly slider 74 to move upward. The assembly telescopic cylinder 73 resets so that the assembly clamping cylinder 76 is above the back cover. Then the assembly clamping cylinder 76 descends and inserts the push rod into the hole in the back cover. The gripper resets.

[0084] This is the eighth process. As the servo motor 45 starts, it drives the lead screw 75 to rotate and drives the second pressing slider 82 and the pressing clamping cylinder 83 to descend simultaneously. When the pneumatic grippers of the pressing clamping cylinder 83 are located on both sides of the assembly, specifically on both sides above the push rod, the pressing clamping cylinder 83 applies clamping force to the push rod to prevent the product from shifting. It should be noted that the pneumatic grippers here are provided with grooves that match the top of the push rod. At the same time, the servo motor 45 continues to run, causing the pressing clamping cylinder 83 to continue to descend and fully insert the push rod into the back cover. The silicone sleeve is then placed on the back cover, thus completing the assembly.

[0085] This is the ninth process. The discharge telescopic cylinder 94 pushes the discharge slider 93 to move the first clamping cylinder 96 above the assembled product. The discharge lifting cylinder 95 pushes the first clamping cylinder 96 down. The first clamping cylinder 96 clamps the push rod. Then, the discharge lifting cylinder 95 and the discharge telescopic cylinder 94 reset. The first clamping cylinder 96 releases the clamped product, and the product falls to the discharge slide 91 and automatically falls into the storage box under the influence of gravity.

[0086] The above design scheme can enable the product to achieve the advantages of improved assembly efficiency, low failure rate, and reduced manufacturing cost.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
