Description

Technical Field

[0001] This invention relates to the field of needle grinding technology, and more specifically, to a needle grinding blade clamping mechanism. Background Technology

[0002] In the prior art, the clamping and moving operation of the grinding clamping mechanism is generally used to clamp and release the stainless steel needle tube 01 so that after the needle tip of the stainless steel needle tube 01 is ground, the needle tip can be taken out and other subsequent processes can be performed.

[0003] Currently, before sharpening fine or short needles, the lower half of the needle tube 01 needs to be held by a clamp 02, leaving space above the needle tube 01 for sharpening. One upper side of the needle tube 01 abuts against a fixed top plate 03, while the other upper side can contact the sharpening equipment for grinding. Because the needle tube 01 abuts against the fixed top plate 03, the top plate 03 cannot move, resulting in insufficient space to remove the sharpened needle tube 01, making subsequent operations on the sharpened needle tube 01 inconvenient.

[0004] In conclusion, how to quickly and easily remove the needle tip after grinding the stainless steel needle tube is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a needle grinding and clamping mechanism that can quickly and conveniently remove the needle after the tip of the stainless steel needle has been ground.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A needle sharpening clamping mechanism, comprising:

[0008] A clamp that can be opened and closed and is used to hold the lower half of a syringe.

[0009] A top plate, which is used to press against the upper half of the needle tube;

[0010] A drive unit for driving the top plate to move;

[0011] The control device is connected to both the clamp and the drive device.

[0012] Preferably, the moving end of the drive device is directly connected to the top plate.

[0013] Preferably, the driving device includes a driving member for reciprocating motion, and the moving end of the driving member is connected to the middle of the top plate;

[0014] Alternatively, the driving device may include at least two driving members for reciprocating motion, the moving ends of the driving members being connected to the top plate, and a plurality of the driving members being symmetrically distributed about the center of the top plate.

[0015] Preferably, the moving end of the drive device is indirectly connected to the top plate.

[0016] Preferably, the driving device includes a driving member for reciprocating motion and a rotating mechanism, the rotating mechanism being rotatably mounted on the frame, the moving end of the driving member being connected to the rotating mechanism, and the top plate being connected to the rotating mechanism.

[0017] Preferably, the rotating mechanism is provided with a positioning pin vertically, which is used to abut against the top plate to determine the position of the top plate.

[0018] Preferably, the driving device includes at least two driving members for reciprocating motion, a rotating mechanism, and a synchronizing component. The rotating mechanism is rotatably mounted on the frame. The moving end of the driving member is connected to the rotating mechanism. The top plate is connected to the rotating mechanism. The tops of multiple rotating mechanisms are all connected to the synchronizing component.

[0019] Preferably, the driving component is a push-pull cylinder that can be pushed outward and pulled inward;

[0020] Alternatively, the drive unit may include a first cylinder for pushing outward and a second cylinder for pulling inward.

[0021] Preferably, the driving device includes a driving component for reciprocating motion and a bracket for supporting the driving component. The position of the driving component is not flush with the position of the top plate, and the moving end of the driving component and the top plate are connected by an L-shaped connecting plate.

[0022] Preferably, the clamp includes two opposing clamping plates and a moving part for driving the clamping plates to move, the moving part being connected to the control device.

[0023] When using the needle sharpening and clamping mechanism provided by this invention, firstly, the control device controls the clamp to open, facilitating the placement of the lower half of the needle into the clamp. Then, the control device controls the clamp to close, effectively clamping the lower half of the needle. Next, the control device controls the drive device to move the top plate closer to the upper half of the needle, causing the top plate and clamp to engage and firmly hold the needle. Then, the needle can be sharpened using a sharpening device. After the needle tip is sharpened, the control device controls the drive device to move in the opposite direction, moving the top plate away from the needle tip. Finally, the control device controls the gripper to operate, gripping the upper half of the needle and transferring the needle.

[0024] In summary, the needle grinding and clamping mechanism provided by this invention can quickly and conveniently remove the needle after the tip of the stainless steel needle has been ground. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The core of this invention is to provide a needle grinding and clamping mechanism that can quickly and conveniently remove the needle after the tip of the stainless steel needle has been ground.

[0041] Please refer to Figures 3 to 9 .

[0042] This specific embodiment provides a needle sharpening clamping mechanism, including:

[0043] Clamp 1, which can be opened and closed, is used to clamp the lower half of the syringe 8;

[0044] Top plate 2, which is used to press the upper half of needle tube 8;

[0045] Drive unit 3, which is used to drive the top plate 2 to move;

[0046] The control device, clamp 1 and drive device 3 are all connected to the control device.

[0047] It should be noted that this device mainly consists of a movable top plate 2 and an openable and closable clamp 1, supplemented by other auxiliary components such as connectors, bolts, and fixing parts to achieve the coordinated linkage between the top plate 2 and the drive device 3. After the needle tip of the needle tube 8 is ground, the top plate 2 used to hold the upper part of the needle tube 8 is a movable top plate 2, that is, the top plate 2 can be moved back to leave space for grinding the needle tip, and also to facilitate the clamping parts to clamp and move the needle tube 8, so as to clamp and remove the needle tube 8 from above, thereby facilitating subsequent other process operations.

[0048] It should also be noted that the gripper may include an openable and closable gripper and a moving device for driving the gripper to move in space. Both the gripper and the moving device are connected to the control device. Therefore, when the control device drives the gripper to run, it can control the gripper to open or close to grip or release the needle tube 8. When the control device drives the moving device to run, it can control the moving device to drive the gripper to move in three-dimensional space to ensure that the ground needle tube 8 is grasped and transferred to a preset position.

[0049] In practical applications, the shape, structure, size, and material of the fixture 1, top plate 2, drive device 3, and control device can be determined according to the actual situation and needs.

[0050] When using the needle sharpening and clamping mechanism provided by this invention, firstly, the control device can control the clamp 1 to open, so that the lower half of the needle tube 8 can be placed into the clamp 1. Then, the control device controls the clamp 1 to close, so as to effectively clamp the lower half of the needle tube 8. Next, the control device controls the drive device 3 to operate, so as to drive the top plate 2 closer to the upper half of the needle tube 8, so that the top plate 2 and the clamp 1 cooperate to clamp the needle tube 8. Then, the needle tube 8 can be sharpened using a sharpening device. After the needle tip of the needle tube 8 has been sharpened, the control device can control the drive device 3 to move in the opposite direction, so that the top plate 2 is away from the needle tip. Finally, the control device can control the clamping member to operate, so that the clamping member clamps the upper half of the needle tube 8 and performs a transfer operation on the needle tube 8.

[0051] In summary, the needle tube sharpening clamping mechanism provided by the present invention can quickly and conveniently remove the needle tube 8 after the tip of the stainless steel needle tube 8 has been sharpened.

[0052] Based on the above embodiments, preferably, the moving end of the drive device 3 is directly connected to the top plate 2 to achieve convenient installation and other effects.

[0053] Preferably, the drive device 3 includes a drive member for reciprocating motion. The moving end of the drive member is connected to the middle of the top plate 2. Therefore, when the drive member performs lateral reciprocating motion, it can drive the top plate 2 to be stably pushed out or pulled back, so that the top plate 2 stably approaches or moves away from the needle tube 8.

[0054] Alternatively, the driving device 3 includes at least two driving members for reciprocating motion. The moving end of the driving member is connected to the top plate 2, and the multiple driving members are symmetrically distributed around the center of the top plate 2. When the top plate 2 is long, multiple driving members can be used to drive the top plate 2 to move, and the multiple driving members are symmetrically distributed around the center of the top plate 2, which can further ensure the synchronous movement of the top plate 2.

[0055] Based on the above embodiments, preferably, the moving end of the driving device 3 and the top plate 2 are indirectly connected to achieve a more compact device structure.

[0056] Preferably, the drive device 3 includes a drive member for reciprocating motion and a rotating mechanism 4. The rotating mechanism 4 is rotatably mounted on the frame 9. The moving end of the drive member is connected to the rotating mechanism 4, and the top plate 2 is connected to the rotating mechanism 4.

[0057] It should be noted that the top plate 2 is horizontally clamped between the frames 9, the moving end of the drive component and the rotating mechanism 4 are horizontally connected, and the fixing pin 5 vertically connects the top plate 2 and the rotating mechanism 4, so as to realize the linkage between the top plate 2 and the rotating mechanism 4 through the fixing pin 5. When the moving end of the drive component pushes outward, the rotating mechanism 4 can rotate outward around a certain fixed point of the rotating mechanism 4, and the rotation process can push the top plate 2 outward; when the moving end of the drive component pulls back inward, the rotating mechanism 4 can rotate inward around the fixed point, and the rotation process can pull the top plate 2 back inward.

[0058] Preferably, the rotating mechanism 4 is vertically provided with a positioning pin 6, which is used to abut against the top plate 2 to determine the position of the top plate 2. That is, when the top plate 2 is pulled back after being pushed out, the positioning pin 6 can abut against the top plate 2 to limit the position of the top plate 2, ensure that the top plate 2 is tightly pressed and prevent the top plate 2 from shaking.

[0059] Based on the above embodiments, preferably, the drive device 3 includes at least two drive members for reciprocating motion, a rotating mechanism 4, and a synchronizing component 7. The rotating mechanism 4 is rotatably mounted on the frame 9. The moving end of the drive member is connected to the rotating mechanism 4, the top plate 2 is connected to the rotating mechanism 4, and the tops of multiple rotating mechanisms 4 are all connected to the synchronizing component 7. The structure is as follows. Figures 5 to 7 As shown.

[0060] It should be noted that the top plate 2 is horizontally clamped between the frames 9, the moving end of the drive component and the rotating mechanism 4 are horizontally connected, and the fixing pin 5 can vertically connect the top plate 2 and the rotating mechanism 4 to achieve linkage between the top plate 2 and the rotating mechanism 4. When the moving end of the drive component pushes outward, the rotating mechanism 4 will rotate outward around a certain fixed point of the rotating mechanism 4, and the rotation process can push the top plate 2 outward; when the moving end of the drive component pulls back inward, the rotating mechanism 4 can rotate inward around that fixed point, and the rotation process can pull the top plate 2 back inward.

[0061] In addition, it should be noted that the indirect connection between the drive component and the top plate 2 is achieved by using the rotating mechanism 4, which can reduce the movement error that occurs during the operation of the drive component. Furthermore, the use of the synchronization component 7 to connect multiple rotating mechanisms 4 can ensure that the long top plate 2 can maintain synchronous movement, thereby improving the synchronization effect and movement accuracy of the top plate 2.

[0062] It should also be noted that frame 9 is used to fix the needle sharpening clamping mechanism to the sharpening equipment, so that the sharpening operation can continue after the needle 8 is fixed. When it is necessary to move the top plate 2, the control device can control the drive component to start working, so as to drive the rotating mechanism 4 to start rotating, thereby driving the top plate 2 to perform forward or backward movements. The synchronization component 7 is provided for the longer top plate 2, so that multiple linkage parts of the top plate 2 keep moving synchronously.

[0063] In practical applications, the shape, structure, size, material, and type of the driving component, rotating mechanism 4, positioning pin 6, and synchronization component 7 can be determined according to the actual situation and needs.

[0064] Preferably, the driving component is a push-pull cylinder that can be pushed outward and pulled inward, with the structure as follows: Figure 9 As shown, the drive unit includes a first cylinder 31 for pushing outward and a second cylinder 32 for pulling inward, with the structure as follows: Figure 5 and Figure 6 As shown. The use of a first cylinder 31 and a second cylinder 32 with unidirectional movement further improves the motion accuracy of the top plate 2 during extension and retraction. Furthermore, the driving component in the above embodiment can be configured as a push-pull cylinder or a lead screw and nut mechanism to ensure that the top plate 2 performs reciprocating extension and retraction operations.

[0065] Preferably, the drive device 3 includes a drive component for reciprocating motion and a bracket for supporting the drive component. The position of the drive component is not flush with the position of the top plate 2, and the moving end of the drive component and the top plate 2 are connected by an L-shaped connecting plate. That is, the moving end of the drive component and the top plate 2 are arranged in layers and connected by an L-shaped connecting plate, so that the drive component drives the top plate 2 to reciprocate. This arrangement can further reduce the assembly space between the drive component and the top plate 2, making the device structure more compact.

[0066] Preferably, the clamp 1 includes two opposing clamping plates and a moving part for driving the clamping plates to move, the moving part being connected to a control device. When it is necessary to clamp the needle tube 8, the control device can control the moving part to move, so as to drive the movable clamping plate closer to the fixed clamping plate, thereby ensuring that the two opposing clamping plates effectively clamp the needle tube 8; when it is necessary to release the needle tube 8, the control device can control the moving part to move in the opposite direction, so as to drive the movable clamping plate away from the fixed clamping plate, thereby preventing the two opposing clamping plates from continuing to clamp the needle tube 8.

[0067] In practical applications, the shape, structure, size, and material of the grippers, moving devices, clamps, and moving parts can be determined according to the actual situation and needs.

[0068] It should be noted that the first cylinder 31 and the second cylinder 32 mentioned in this application are only distinguished by their different positions and do not have any order of precedence.

[0069] In addition, it should be noted that the orientation or positional relationship indicated by "up and down" or "front and back" in this application is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the purpose of simplifying the description and making it easier to understand, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention.
