Description

Technical Field

[0001] This invention belongs to the technical field of tweezers sheathing equipment, and more specifically, relates to a tweezers sheathing device. Background Technology

[0002] Tweezers are commonly used manual gripping tools in laboratories, electronic assembly, and precision machining. They are typically made of stainless steel, titanium alloy, or antistatic plastic with a one-piece flexible arm structure. The gripping force is generated by pinching the two tips with the fingers, and they are used to pick up, transfer, and place small objects (such as biological slides, electronic components, and tiny parts) or perform precise positioning operations. During the manufacturing of tweezers, because the tips are sharp, they need to be covered with plastic sleeves for protection. Traditionally, this was done manually, which was inefficient. Summary of the Invention

[0003] In view of the problems in the related technologies, the present invention proposes a tweezers sheath device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] The present invention is a tweezers sleeve device, including a frame, on which a feeding part, a conveying part, a sleeve part and an unloading part are arranged in sequence. The conveying part includes a conveyor belt and a conveying fixture installed on the conveyor belt that can move and convey with the conveyor belt. The conveying fixture is provided with a positioning groove adapted to the tweezers.

[0006] The feeding section includes a vibrating screen, a preparation platform, and a pusher. The preparation platform is fixedly installed on one side of the starting end of the conveyor belt, and a feeding chute extending towards the conveyor belt is provided on the preparation platform. The vibrating screen can vibrate and transport the tweezers into the feeding chute on the preparation platform. The pusher can push the tweezers along the feeding chute into the positioning groove in the conveying fixture. The conveyor belt can transport the conveying fixture and the tweezers towards the sleeve section.

[0007] The sleeve part includes a sleeve reel, pneumatic scissors, and a sleeve extension cylinder. A sleeve roll is wound on the sleeve reel. The sleeve extension cylinder can clamp the end of the sleeve roll and stretch and unwind it, and put the end of the sleeve onto the tip of the tweezers. The pneumatic scissors can cut the sleeve to separate the sleeve roll from the sleeve at the tip of the tweezers.

[0008] The unloading section can clamp and unload tweezers with sleeves from the conveying fixture.

[0009] Furthermore, the pushing component includes a pushing cylinder, which is mounted on the upper part of the preparation platform via a bracket and is arranged in the same direction as the preparation platform. A pressing cylinder is fixedly installed on the telescopic end of the pushing cylinder, and a feeding pressure plate is fixedly installed on the telescopic end at the bottom of the pressing cylinder.

[0010] Furthermore, the conveying unit also includes a positioning cylinder, which is fixedly installed on the top surface of the frame and located on one side of the conveyor belt. The telescopic end of the positioning cylinder is fixedly installed with a positioning block corresponding to the material preparation table.

[0011] Furthermore, the conveying unit also includes a pressing cylinder, which is fixedly installed above the conveyor belt by a bracket, and a pressing plate is fixedly installed at the telescopic end at the bottom of the pressing cylinder.

[0012] Furthermore, the sleeve part also includes a limiting cylinder, which is fixedly installed above the sleeve station on the conveyor belt by a bracket, and a limiting pressure plate is fixedly installed on the telescopic end at the bottom of the limiting cylinder.

[0013] Furthermore, the casing section also includes a casing clamping cylinder, which can clamp and fix the unwinding portion of the casing coil.

[0014] Furthermore, the unloading section includes a displacement cylinder, which is fixedly installed above the end of the conveyor belt, and a lifting cylinder is fixedly installed on the telescopic end of the displacement cylinder, and a clamping cylinder is fixedly installed on the telescopic end of the lifting cylinder.

[0015] Furthermore, a collection bucket located below the end of the displacement cylinder's displacement stroke is fixedly installed on the frame.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this invention, a vibrating screen and a pusher work together to feed tweezers into a conveyor fixture on a conveyor belt. Then, the conveyor belt transports the conveyor fixture and tweezers to a sleeve station located on one side of the sleeve section. Next, a sleeve extension cylinder clamps the end of the sleeve roll, stretches and unwinds it, and places the end of the sleeve onto the tip of the tweezers. Then, a pneumatic shear cuts the sleeve to separate the sleeve roll from the sleeve at the tip of the tweezers, thus realizing automatic sleeve sleeve at the tip of the tweezers. Compared with manual sleeve sleeve, this improves the sleeve sleeve efficiency of the tweezers.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0033] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0034] Please see Figures 1-11 As shown, the present invention is a tweezers sleeve device, including a frame 1. The frame 1 is provided with a feeding part 2, a conveying part 3, a sleeve part 4 and a discharging part 5 arranged in sequence. The conveying part 3 includes a conveyor belt 31 and a conveying fixture 32 installed on the conveyor belt 31 and able to move and convey with the conveyor belt 31. The conveying fixture 32 is provided with a positioning groove adapted to the tweezers.

[0035] The feeding section 2 includes a vibrating screen 25, a preparation platform 24, and a pusher. The preparation platform 24 is fixedly installed on one side of the starting end of the conveyor belt 31, and a feeding chute extending towards the conveyor belt 31 is provided on the preparation platform 24. The vibrating screen 25 can vibrate and transport the tweezers into the feeding chute on the preparation platform 24. The pusher can push the tweezers along the feeding chute into the positioning groove in the conveying fixture 32. The conveyor belt 31 can transport the conveying fixture 32 and the tweezers towards the sleeve section 4.

[0036] The sleeve section 4 includes a sleeve reel 41, pneumatic scissors 44 and a sleeve extension cylinder 45. A sleeve reel is wound on the sleeve reel 41. The sleeve extension cylinder 45 can clamp the end of the sleeve reel and stretch and unwind it, and put the end of the sleeve on the tip of the tweezers. The pneumatic scissors 44 can cut the sleeve so that the sleeve reel is separated from the sleeve at the tip of the tweezers.

[0037] The unloading section 5 can clamp and unload the tweezers with sleeves from the conveying fixture 32.

[0038] The vibrating screen 25 is a vibrating conveyor tray that vibrates and conveys the tweezers inside to the feeding chute on the preparation platform 24. The conveyor belt 31 drives the conveying fixture 32 on it to move cyclically. When the conveying fixture 32 moves to one side of the preparation platform 24, the conveyor belt 31 stops conveying, so that the conveying fixture 32 is aligned and placed on one side of the preparation platform 24. Then, the pusher pushes the tweezers along the feeding chute into the positioning slot in the conveying fixture 32. Then, the conveyor belt 31 drives the conveying fixture 32 to continue conveying, so that the conveying fixture 32 and the tweezers inside are conveyed to the sleeve station on one side of the sleeve part 4. Then, the conveyor belt 31 stops conveying again. The tube extension cylinder 45 clamps the end of the sleeve roll with a pneumatic gripper on its telescopic end. Then, the tube extension cylinder 45 extends to stretch and unwind the sleeve roll with the pneumatic gripper, and puts the end of the sleeve roll onto the tip of the tweezers in the conveying fixture 32. Then, the pneumatic scissors 44 cuts and separates the sleeve roll body from the sleeve on the tip of the tweezers. Finally, the unloading unit 5 clamps the tweezers with the sleeve on from the conveying fixture 32 and unloads them, thus completing the sleeve operation on the tip of the tweezers. Moreover, the automatic sleeve of the tweezers tip is achieved through the cooperation of the feeding unit 2, the conveying unit 3, the sleeve unit 4, and the unloading unit 5, which can significantly improve the sleeve efficiency of the tweezers compared to manual sleeve.

[0039] Specifically, the pushing component includes a pushing cylinder 21, which is mounted on the upper part of the preparation platform 24 via a bracket, and the pushing cylinder 21 and the preparation platform 24 are arranged in the same direction. A pressing cylinder 22 is fixedly installed on the telescopic end of the pushing cylinder 21, and a feeding pressure plate 23 is fixedly installed on the telescopic end at the bottom of the pressing cylinder 22.

[0040] After the tweezers are vibrated and conveyed by the vibrating screen 25 into the feeding chute on the top surface of the preparation platform 24, the pressing cylinder 22 drives the feeding plate 23 to move downward so that the feeding plate 23 presses on the top of the tweezers. Then, the pushing cylinder 21 drives the pressing cylinder 22 and the feeding plate 23 to move synchronously towards the conveyor belt 31. At this time, the feeding plate 23 can push the tweezers towards the conveyor belt 31 through the pushing block at the tail, so that the tweezers are pushed and conveyed from the preparation platform 24 into the conveying fixture 32 on the conveyor belt 31.

[0041] Specifically, the conveying unit 3 also includes a positioning cylinder 33, which is fixedly installed on the top surface of the frame 1 and located on one side of the conveyor belt 31. The telescopic end of the positioning cylinder 33 is fixedly installed with a positioning block 34 corresponding to the material preparation table 24.

[0042] The positioning block 34 and the preparation table 24 are located on both sides of the conveyor belt 31, and the positioning block 34 has a groove corresponding to the end of the tweezers on the side closest to the conveyor belt 31. When the pusher pushes the tweezers from the preparation table 24 into the conveying fixture 32, the positioning cylinder 33 drives the positioning block 34 to move and fit tightly against one side of the conveying fixture 32. The groove on the side of the positioning block 34 abuts and limits the end of the tweezers in the conveying fixture 32, preventing the tweezers from being pushed and displaced excessively. This improves the accuracy of the tweezers' positioning in the conveying fixture 32. After the tweezers are pushed and positioned, the positioning cylinder 33 drives the positioning block 34 to move in the opposite direction and reset, so that the positioning block 34 is separated from the end of the tweezers and does not affect the subsequent conveying of the tweezers.

[0043] Specifically, the conveying unit 3 also includes a pressing cylinder 35, which is fixedly installed above the conveyor belt 31 by a bracket, and a pressing plate 36 is fixedly installed at the telescopic end of the bottom of the pressing cylinder 35.

[0044] When the conveyor fixture 32 and the tweezers are conveyed to the bottom of the pressure plate 36 by the conveyor belt 31, the conveyor belt 31 stops conveying, and at the same time the pressure cylinder 35 drives the pressure plate 36 to move downward, so as to press the tweezers in the conveyor fixture 32 into the fixture groove through the pressure plate 36, so as to further improve the accuracy of the placement of the tweezers in the conveyor fixture 32.

[0045] Specifically, the sleeve part 4 also includes a limiting cylinder 42, which is fixedly installed above the sleeve station on the conveyor belt 31 by a bracket, and a limiting pressure plate 43 is fixedly installed on the telescopic end at the bottom of the limiting cylinder 42.

[0046] When the conveying fixture 32 carries the tweezers to the sleeve station on one side of the sleeve section 4, the limiting cylinder 42 drives the limiting pressure plate 43 to move downward, so that the limiting pressure plate 43 presses and fixes the tweezers in the conveying fixture 32, thereby preventing the tweezers from moving backward under the sleeve thrust during sleeve installation and ensuring the stable operation of the sleeve installation process.

[0047] Specifically, the casing section 4 also includes a casing clamping cylinder 46, which can clamp and fix the unwinding part of the casing coil.

[0048] The end of the sleeve clamping cylinder 46 is equipped with a pneumatic gripper. When the sleeve extension cylinder 45 pulls the sleeve roll to unwind, the pneumatic gripper at the end of the sleeve clamping cylinder 46 is in an open state, so that the sleeve roll can be freely stretched and unwound. When the sleeve roll body is separated from the sleeve on the tip of the tweezers by the pneumatic scissors 44, the pneumatic gripper at the end of the sleeve clamping cylinder 46 clamps and fixes the unwinding part of the sleeve roll. Then, the sleeve roll is cut by the pneumatic scissors 44. Thus, the new end of the sleeve roll after being cut can be clamped and positioned by the pneumatic gripper, so that the sleeve extension cylinder 45 can find the end of the sleeve roll again and pull the sleeve roll to unwind.

[0049] Furthermore, during the tweezers transport process, the tip of the tweezers is tilted upwards at a certain angle, while only the tail of the tweezers is clamped in the fixture groove of the transport fixture 32, with the tip extending obliquely out of the fixture groove. The tweezers are retracted by the fixture groove of the transport fixture 32, causing the two clamping parts of the tip to abut against each other. The sleeve extension cylinder 45 and the sleeve clamping cylinder 46 are also installed at an angle. The sleeve extension cylinder 45 clamps the sleeve and pulls the end of the sleeve out of the sleeve roll, then places it on the tip of the tweezers, simultaneously clamping both clamping parts of the tweezers tip. Therefore, the end of the sleeve and the tip of the tweezers are on the same inclined plane. Since the sleeve end also needs to be cut and separated, if the sleeve is not clamped during cutting, it may retract. Therefore, before activating the pneumatic shears 44, the sleeve clamping cylinder 46 needs to clamp the sleeve to prevent retraction. The cutting part of the pneumatic scissors 44 is set perpendicular to the tip of the tweezers, so that the end face of the sleeve after cutting will be neater.

[0050] Specifically, the unloading unit 5 includes a shifting cylinder 52, which is fixedly installed above the end of the conveyor belt 31. A lifting cylinder is fixedly installed at the telescopic end of the shifting cylinder 52, and a clamping cylinder 53 is fixedly installed at the telescopic end of the lifting cylinder. A collection bucket 51 located below the end of the shifting stroke of the shifting cylinder 52 is fixedly installed on the frame 1.

[0051] After the tweezers are sleeved at the end, the conveyor belt 31 continues to transport the conveyor fixture 32 and the tweezers backward until the conveyor fixture 32 and the tweezers move to the lower position of the clamping cylinder 53. The lifting cylinder first drives the clamping cylinder 53 downward so that the clamping cylinder 53 can clamp and fix the tweezers in the conveyor fixture 32. Then the lifting cylinder drives the clamping cylinder 53 upward to reset so that the clamping cylinder 53 can clamp the tweezers upward and separate the tweezers from the conveyor fixture 32. Then the shifting cylinder 52 drives the lifting cylinder, the clamping cylinder 53 and the tweezers to move backward synchronously so as to move and transport the tweezers to the top of the collection bucket 51. Finally, the clamping cylinder 53 releases its grip on the tweezers, so that the tweezers fall and are transported into the collection bucket 51, thereby completing the unloading and collection of the tweezers.
