Description

Technical Field

[0001] This utility model relates to the field of gripper mechanism technology, specifically a gripper mechanism that can simultaneously clamp and rotate. Background Technology

[0002] A gripper mechanism is a mechanical structure used to grasp, hold, or manipulate objects. It's used for handling items, clamping materials, etc. The design goals of gripper mechanisms are typically to achieve efficient and reliable operation, while maximizing flexibility and adaptability to handle objects of different shapes and sizes. With technological advancements, modern gripper mechanisms are becoming increasingly important, enabling convenient use in more scenarios to meet increasingly complex operational requirements. Currently, achieving rotation and clamping requires the use of pneumatic grippers. However, when a pneumatic gripper rotates, the air hose connected to it (for air supply) must also move, which can cause the hose to become tangled, resulting in insufficient air supply and affecting the normal operation of the pneumatic gripper. Utility Model Content

[0003] The present invention addresses the shortcomings of the prior art by providing a gripper mechanism that can simultaneously clamp and rotate. This solves the problem that existing pneumatic grippers are required to achieve both rotation and clamping, but when performing rotation, the air tubes are prone to tangling, resulting in insufficient air supply and affecting the normal use of the pneumatic grippers.

[0004] Specifically, the gripper assembly can clamp and fix the battery cell tabs, while the rotating shaft is rotatably connected to the fixed base, allowing the material to be clamped and rotated simultaneously. This can be used in battery cell tab alignment mechanisms, solving the problem that when existing pneumatic grippers rotate, the air pipes connected to the grippers (used for air supply) must also move, which can cause the air pipes to become knotted. This ensures that the battery cell tabs are clamped securely.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A gripper mechanism capable of simultaneously clamping and rotating includes: a fixed base, wherein a rotating shaft is movably connected inside the fixed base;

[0007] A pull rod is movably installed inside the rotating shaft, and a spring is sleeved on the pull rod, with both ends of the spring fixed to the rotating shaft and the pull rod respectively.

[0008] A gripper assembly is provided on each side of the rotating shaft. The pull rod is connected to the two gripper assemblies. When the pull rod moves downward, it drives the two gripper assemblies to move closer to each other, so that the two gripper assemblies clamp and fix the battery cell tabs.

[0009] In a further preferred embodiment, in one of the gripper assemblies, the gripper assembly includes a sliding plate and grippers, a placement groove is provided on the rotating shaft, the sliding plate is movably disposed in the placement groove, and the grippers are mounted on the sliding plate.

[0010] In a further preferred embodiment, both sliding plates are provided with inclined grooves, which are arranged intersectingly. The pulling rod is provided with a fixing groove, which is connected to the two inclined grooves, so that the pin provided on the pulling rod can pass through the fixing groove and the two inclined grooves.

[0011] In a further preferred embodiment, a limit block is installed on the pull rod, and one end of the spring is fixed to the limit block.

[0012] In a further preferred embodiment, the rotating shaft is fitted with a bearing, and the rotating shaft is rotatably connected to the fixed base via the bearing.

[0013] In a further preferred embodiment, the rotating shaft is a stepped shaft, and a retaining ring is fitted onto the stepped shaft to confine the bearing to the stepped shaft.

[0014] In a further preferred embodiment, two bearings are provided, with each bearing disposed between the rotating shaft and the fixed base.

[0015] In a further preferred embodiment, a pressure block is installed on the top of the rotating shaft, and the pressure block has a connecting through hole that communicates with the rotating shaft.

[0016] In a further preferred embodiment, the bottom of the gripper is provided with a mounting groove, and one end of the sliding plate is embedded in the mounting groove.

[0017] In a further preferred embodiment, both the gripper and the sliding plate are provided with fixing holes for installing screws or bolts.

[0018] The advantages and beneficial effects of this utility model compared to the prior art are as follows:

[0019] The battery cell tabs can be clamped and fixed by using a combination of placement groove, sliding plate, inclined groove, gripper, pull rod and spring. The rotating shaft is rotatably connected to the fixed base, which can rotate while clamping the material. It can be used in battery cell tab alignment and other mechanisms, which solves the problem of air tube tangling when existing pneumatic grippers perform rotation, and ensures that the battery cell tabs are clamped.

Detailed Implementation

[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] Please see Figures 1-6 A clamping and rotating gripper mechanism includes: a fixed base 1, a rotating shaft 101 movably connected inside the fixed base 1, a pull rod 203 movably installed inside the rotating shaft 101, a spring 204 sleeved on the pull rod 203, and the two ends of the spring 204 being fixed to the rotating shaft 101 and the pull rod 203 respectively. A gripper assembly is provided on each side of the rotating shaft 101. The pull rod 203 is connected to the two gripper assemblies. When the pull rod 203 moves downward, it drives the two gripper assemblies to move closer to each other, so that the two gripper assemblies clamp and fix the battery cell tabs.

[0029] In a gripper assembly, the gripper assembly includes a sliding plate 201 and a gripper 202. A placement groove 2 is provided on the rotating shaft 101. The sliding plate 201 is movably disposed in the placement groove 2. The gripper 202 is mounted on the sliding plate 201. Both sliding plates 201 are provided with inclined grooves 201a. The two inclined grooves 201a are arranged intersectingly. A fixing groove 203a is provided on the pulling rod 203. The fixing groove 203a and the two inclined grooves 201a are connected to each other so that the pin provided on the pulling rod 203 can pass through the fixing groove 203a and the two inclined grooves 201a.

[0030] Please see Figure 1 and Figure 2 When the fixed base 1 is in use, the rotating shaft 101 is placed inside the fixed base 1, and the pull rod 203 is installed inside the rotating shaft 101. The top of the pull rod 203 is equipped with a sliding plate 201 and a gripper 202. That is, the sliding plate 201 is located inside the placement groove 2. When clamping and fixing the battery cell tab, the spring 204 pushes the pull rod 203 downward to pull the sliding plate 201. The sliding plate 201 slides downward under force inside the inclined groove 201a, thereby driving the gripper 202 to clamp. That is, the gripper 202 is installed on the rotating shaft 101, which makes it easy to clamp and fix the battery cell tab. The rotating shaft 101 is rotatably connected to the fixed base 1, which can clamp the material while rotating. It can be used in battery cell tab alignment and other mechanisms to solve the problem that when the existing pneumatic gripper performs rotation, the air pipe (used for air supply) connected to the pneumatic gripper must also move with it, which will cause the air pipe to become knotted. This ensures that the battery cell tab is clamped.

[0031] Please see Figure 2 A pressure block 4 is installed on the top of the rotating shaft 101, and a connecting through hole 401 is provided on the pressure block 4 to communicate with the rotating shaft 101.

[0032] When the sliding plate 201 is used inside the top of the rotating shaft 101, the pressure block 4 is installed on the top of the rotating shaft 101 to limit the sliding plate 201, preventing the sliding plate 201 from sliding out from inside the top of the rotating shaft 101, ensuring the normal use of the sliding plate 201 and the clamp 202. During the clamping and fixing of the battery cell tab by the clamp 202, the through hole 401 can prevent the battery cell tab from touching the pressure block 4 and causing damage.

[0033] It should be noted that a limit block 205 is installed on the pull rod 203, and one end of the spring 204 is fixed to the limit block 205. When the spring 204 is used on the pull rod 203, the limit block 205 at the bottom of the pull rod 203 can limit the spring 204 and prevent the spring 204 from slipping off the pull rod 203.

[0034] Please see Figure 6The rotating shaft 101 is fitted with a bearing 206, and the rotating shaft 101 is rotatably connected to the fixed seat 1 through the bearing 206. The rotating shaft 101 is a stepped shaft, and a retaining ring 207 is fitted on the stepped shaft. The retaining ring 207 is used to limit the bearing 206 on the stepped shaft. There are two bearings 206, which are respectively set between the rotating shaft 101 and the fixed seat 1. When the rotating shaft 101 is placed inside the fixed seat 1, the rotating shaft 101 is rotatably connected to the fixed seat 1 through the bearing 206, which can ensure that the rotating shaft 101 drives the gripper 202 to rotate for operation.

[0035] Please see Figure 2 The bottom of the gripper 202 is provided with a mounting groove 3. One end of the sliding plate 201 is embedded in the mounting groove 3. Both the gripper 202 and the sliding plate 201 are provided with fixing holes 301. The fixing holes 301 are used to install screws or bolts. When the sliding plate 201 is in use, it is inserted into the mounting groove 3. The mounting holes 301 on the outside of the sliding plate 201 are connected to the mounting groove 3. When the sliding plate 201 and the mounting groove 3 are tightly fitted, the mounting holes 301 on the outside of the sliding plate 201 are aligned with the mounting holes 301 on the outside of the gripper 202. The bolts are tightened inside the mounting holes 301 to fix the sliding plate 201 and the gripper 202.

[0036] Please see Figure 5 When installing the sliding plate 201 and the pull rod 203, the sliding plate 201 is inserted into the fixing groove 302 and fixed with screws, so that the pull rod 203 can pull the sliding plate 201 to slide under force in the placement groove 2.

[0037] Please see Figure 3 and Figure 4 When the sliding plate 201 is used inside the top of the rotating shaft 101, the pressure block 4 is installed on the top of the rotating shaft 101 to limit the sliding plate 201, preventing the sliding plate 201 from sliding out from inside the top of the rotating shaft 101, ensuring the normal use of the sliding plate 201 and the clamp 202. During the clamping and fixing of the battery cell tab by the clamp 202, the through hole 401 can prevent the battery cell tab from touching the pressure block 4 and causing damage.

[0038] Finally, when the spring 204 is used on the pull rod 203, the limiting block 205 at the bottom of the pull rod 203 can limit the placement of the spring 204 to prevent the spring 204 from slipping off the pull rod 203.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
