Description

Technical Field

[0001] This utility model relates to the field of new energy battery module production equipment, and in particular to an electrode sheet fixing clamp. Background Technology

[0002] Electrode sheets are an important component of new energy batteries. During the processing of electrode sheets, special fixtures are usually used to clamp the blank sheets, and then they are transferred on the production line according to the process. Since the electrode sheets themselves are relatively thin, it is necessary to ensure the stability of the clamping without damaging the surface of the electrode sheets. Traditional fixtures are generally clamping fixtures. These fixtures clamp directly from top to bottom during clamping. Although the clamping speed is fast, the clamping force cannot be automatically adjusted according to the condition of each electrode sheet. Sometimes this can lead to excessive force on the surface, resulting in indentations and the formation of defective products. Utility Model Content

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] Please see Figures 1 to 5 The embodiments of this utility model include:

[0027] An electrode sheet fixing fixture includes: a clamping base 2, a gripper mechanism, and a gripper driving mechanism, both of which are mounted on the clamping base 2. The clamping base 2 has two symmetrically arranged mounting slopes on its top, dividing it into a base plate 201 with a rectangular cross-section and a positioning platform 202 with an isosceles trapezoidal cross-section. An electrode sheet pad 8 is mounted on the upper surface of the positioning platform 202. The gripper mechanism consists of two sets, symmetrically mounted on the two mounting surfaces. On the inclined surface, each gripper mechanism includes a gripper push rod 6 and a gripper head 7. The top end of the gripper push rod 6 and the tail end of the gripper head 7 are rotatably connected by a pin 11. The electrode pad 8 is an I-beam with symmetrically arranged grooves on both sides. Gripper rotating shafts 10 are symmetrically installed in the two grooves. A gripper head 7 is rotatably installed on each gripper rotating shaft 10. The rod body 602 of the gripper push rod 6 is installed in a pre-set push rod hole 207 on the inclined surface of the corresponding side of the positioning table 202. The bottoms of the push rod holes 207 on the inclined surface are interconnected; the gripper drive mechanism includes a gripping drive shaft 3 and a top block 4; a transversely penetrating drive shaft mounting hole and a top block limiting slide groove 203 are provided in the middle of the base plate 201; the drive shaft mounting hole is provided with an internal thread; the opening of the top block limiting slide groove 203 is located at the bottom of the base plate 1; a dust cover 209 is installed on the opening; the groove body vertically passes through the midpoint of the drive shaft mounting hole; and the top is connected to the bottom connection position of the two push rod holes 207. The clamping drive shaft 3 includes a front pressure cover 301, a shaft body, and a limiting cover 205. The shaft body is provided with external threads, and a tapered guide section 303 is provided in the middle of the shaft body. The length of the tapered guide section 303 and the length of the drive shaft mounting hole are equal to the length of the shaft body. The clamping drive shaft 3 and the top block 4 are respectively installed in the drive shaft mounting hole and the top block limiting groove 203. The bottom of the top block 4 abuts against the surface of the tapered guide section 303 of the clamping drive shaft 3, and the top abuts against the two gripper push rods 6.

[0028] The angle between the mounting ramp and the base plate 201 is 30° to 60°, and in actual implementation, the angle is generally 45°. The push rod hole 207 is perpendicular to the opening of the corresponding mounting ramp. In this way, the lever effect of the gripper push rod 6 on the gripper head 7 is maximized, resulting in the best clamping stability on the gripper head 7.

[0029] The gripper push rod 6 includes a rod body 602 and a rod foot 602. The top of the rod body 602 has a pin hole for connection to the gripper head 7. The outer diameter of the rod foot 602 is clearance-fitted with the inner diameter of the push rod hole 207. The diameter of the rod body 602 is smaller than the diameter of the rod foot 602. A return spring 9 is mounted on the rod body 602. A spring cover plate 5 is mounted on the push rod hole 207. The spring cover plate 5 has a rod body through hole in the middle, the diameter of which is between the diameter of the return spring 9 and the diameter of the rod body 602. The rod foot 601 has a splicing surface. When both gripper push rods 6 are fully reset simultaneously, the two splicing surfaces are perfectly aligned. In this way, when the gripping drive shaft 3 is released, the return spring 9 can push the gripper push rod 6 to automatically and quickly reset, significantly improving reset efficiency. Moreover, after reset, the splicing of the rod feet 601 maximizes the extension stroke of the two gripper push rods 6 when the top block 4 is ejected. A pressure cover protection step 208 is also provided on the inclined surface above the opening of the push rod hole 207. By setting the pressure cover protection step 208, the tail end of the gripper head 77 can be prevented from hitting the spring cover plate 5 when the gripper push rod 6 is pulled down, thus preventing damage to the surface of the spring cover plate 5.

[0030] The gripper head 7 includes a lower connecting rod 701, an upper connecting rod 702, and a pressure head 703. The lower connecting rod 701 has a connecting groove 704 at its tail, and a pin 11 connected to the gripper push rod 6 is installed in the connecting groove 704. The pressure head 703 is vertically mounted on the top of the upper connecting rod 702. The angle between the lower connecting rod 701 and the upper connecting rod 702 is the angle between the mounting slope and the substrate 201 plus 90°. A rotation shaft mounting hole is provided at the connection position between the lower connecting rod 701 and the upper connecting rod 702. The bending angle of the gripper head 7 can match the angle of the mounting slope. When the gripper push rod 6 is fully reset, the upper connecting rod 702 can remain vertical, and the pressure head is positioned directly above the electrode pad 8, reducing the required movement range of the gripper push rod 6 during clamping.

[0031] The tapered guide section 303 divides the shaft body into a front threaded connection section 302 and a rear threaded connection section 302. A buffer chamber 204 is provided in the middle of the drive shaft mounting hole. The buffer chamber 204 divides the drive shaft mounting hole into a front positioning mounting hole 205 and a rear positioning mounting hole 206. When the clamping drive shaft 3 is installed, the front threaded connection section 302 and the rear threaded connection section 304 are respectively installed into the front positioning mounting hole 205 and the rear positioning mounting hole 206. The length of the buffer chamber 204 is not less than the length of the tapered guide section 303, and is generally equal to the length of the tapered guide section 303. The bottom of the push rod hole 207 is located at the top of the buffer chamber 204. The reason for setting up the buffer chamber 204 is that the entire drive structure is very compact and has a large longitudinal force. Without a large buffer space, the drive shaft may get stuck due to slight deformation under force during actual use, making it difficult to continue working. The connection between the bottom of the push rod 207 and the top of the buffer chamber 204 can reduce the transmission distance of the top block 4 and reduce the overall friction. It also makes it easy to set the top block 4 as a cylinder with a circular cross-section. The advantage of using a cylindrical structure is that the top block 4 can adjust the force at the contact position by rotating when it contacts the conical guide section 303, reducing the resistance when pushing upward.

[0032] The actual working method of this embodiment is as follows: In actual use, first rotate the clamping drive shaft 3 so that the front end of the clamping drive shaft 3 is away from the base 201 to the maximum position. At this time, the lowest point of the tapered guide section 303 on the shaft body is located in the top block limiting groove 203. At this time, under the action of the return spring 9, the rod feet 601 of the two gripper push rods 6 are located at the bottom of the corresponding push rod holes 207, and the inclined surfaces on the two rod feet 601 are just joined together. At this time, the distance between the two pressure heads 703 and the electrode pad 8 is the maximum. Under this condition, the on-site personnel manually or through special equipment place the electrode 1 to be processed on the electrode pad 8, and then... Rotating the clamping drive shaft 3 in the reverse direction pushes the conical guide section 303 backward, gradually raising the portion overlapping with the top block limiting groove 203, thereby pushing the top block 4 upward. During the upward movement of the top block 4, the top pushes the two claw push rods 6 outward along the corresponding push rod holes 207. When the claw push rods 6 are pushed out, their top ends press against the lower connecting rod of the claw head 7, causing the claw head 7 to rotate around the rotating shaft 10, thereby pressing the pressure head 703 tightly onto the electrode sheet 1, completing the clamping action. After processing, simply rotating the clamping drive shaft 3 in the reverse direction will release the electrode sheet 1, making it convenient for on-site personnel to remove the electrode sheet 1 from the electrode sheet pad 8.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
