Description

Technical Field

[0001] This utility model belongs to the field of lithium battery processing technology, and in particular relates to a clamping device for lithium battery processing. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. During the processing of lithium batteries, such as cutting, grinding or welding, clamping devices are usually required to fix the lithium batteries in place.

[0003] The clamping force of existing clamping devices is not easy to adjust, and it is easy to damage the lithium batteries themselves when clamping lithium batteries of different specifications, resulting in unnecessary economic losses. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for lithium battery processing, which solves the problem that the clamping force of existing clamping devices is inconvenient to adjust, and that the lithium batteries are easily damaged when clamping lithium batteries of different specifications, resulting in unnecessary economic losses.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a clamping device for lithium battery processing, comprising a base and a clamping assembly. Connecting rods are fixedly connected to both sides of one end of the base. The connecting rods are L-shaped, and a sliding frame is fixedly connected to one end of each of the two sets of connecting rods. The sliding frame is inclined and positioned diagonally above the base. A fixing rod is fixedly connected to one side of the sliding frame, and a mounting frame is fixedly connected to one end of the fixing rod. An electric push rod is installed within the mounting frame. A power supply is installed on one side of the bottom surface of the mounting frame. A pressure switch is installed on the side of the sliding frame near the limiting rod. The pressure switch is electrically connected to the power supply, and the electric push rod is electrically connected to the pressure switch.

[0007] The output end of the electric push rod passes through the mounting frame and is fixedly connected to a connector. The upper and lower ends of the connector are respectively hinged to hinge plates. One end of each of the two sets of hinge plates is respectively hinged to two sets of linkage rods. The hinge plates are located on the outside of the sliding frame.

[0008] The clamping assembly includes an electric push rod, a linkage rod, and a linkage plate. Two sets of linkage rods are provided, each set located within a sliding frame and slidingly engaged with it. One end of each linkage rod is fixedly connected to a connecting frame. Multiple sets of limiting holes are evenly distributed on the surface of the other end of each linkage rod. A limiting rod is inserted into one set of these limiting holes and is located on one side of the sliding frame. The connecting frame is located on the outside of the sliding frame and is L-shaped. Two sets of linkage plates are provided, each set located within a connecting frame and hinged to it. A clamping head is fixedly connected to the other end of each linkage plate and is located on the outside of the connecting frame, above the base.

[0009] A connecting rod is fixedly connected inside one end of the connecting frame. The linkage plate is "L" shaped, and a cooperating spring is fixedly connected between one side of the linkage plate and the connecting rod. By setting the cooperating spring, the movement trajectory of the linkage plate driving the clamping head is stable, while avoiding rigid clamping of the lithium battery.

[0010] This utility model has the following beneficial effects:

[0011] This invention utilizes a clamping assembly to place a lithium battery on a base between two sets of clamping heads. The position of the limiting rod is adjusted according to the specifications of the lithium battery to be clamped. Then, an electric push rod is activated, causing it to move two sets of linkage rods within a sliding frame via a connector and hinge plate. The movement of the linkage rods drives a linkage plate through the connector, which in turn moves the clamping heads to clamp the lithium battery. While the clamping heads are clamping and fixing the battery, the movement of the linkage rods causes the limiting rod to contact a pressure switch on the sliding frame, immediately de-energizing the electric push rod and stopping its operation. This effectively clamps and fixes the lithium battery while preventing excessive clamping force that could damage it. Furthermore, the use of limiting rods and limiting holes facilitates adjustment for clamping different specifications of lithium batteries, making it highly adaptable.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1-3As shown, this utility model is a clamping device for lithium battery processing, including a base 1 and a clamping assembly 2. Connecting rods 101 are fixedly connected to both sides of one end of the base 1. The connecting rods 101 are "L" shaped. A sliding frame 102 is fixedly connected to one end of each of the two sets of connecting rods 101. The sliding frame 102 is inclined and is located diagonally above the base 1. A fixing rod 103 is fixedly connected to one side of the sliding frame 102. A mounting frame 104 is fixedly connected to one end of the fixing rod 103. An electric push rod 201 is installed inside the mounting frame 104. A power supply is installed on one side of the bottom surface of the mounting frame 104. A pressure switch is installed on the side of the sliding frame 102 near the limiting rod 204. The pressure switch is electrically connected to the power supply. The electric push rod 201 is electrically connected to the pressure switch.

[0023] The output end of the electric push rod 201 passes through the mounting frame 104 and is fixedly connected to the connector 210. The upper and lower ends of the connector 210 are respectively hinged to the hinge plate 211. One end of the two sets of hinge plates 211 is respectively hinged to the two sets of linkage rods 202. The hinge plate 211 is located on the outside of the sliding frame 102.

[0024] The clamping assembly 2 includes an electric push rod 201, a linkage rod 202, and a linkage plate 208. There are two sets of linkage rods 202, which are respectively set in two sets of sliding frames 102 and slide in cooperation with the sliding frames 102. One end of each set of linkage rods 202 is fixedly connected to a connecting frame 206. Multiple sets of limiting holes 203 are evenly distributed on the surface of the other end of the linkage rod 202. A limiting rod 204 is inserted into the inside of one set of limiting holes 203. The limiting rod 204 is set on one side of the sliding frame 102.

[0025] The connecting frame 206 is located on the outside of the sliding frame 102. The connecting frame 206 is "L" shaped. There are two sets of linkage plates 208. One end of each set of linkage plates 208 is located inside the two sets of connecting frames 206 and is hinged to the connecting frame 206. The other end of the linkage plate 208 is fixedly connected to a clamping head 205. The clamping head 205 is located on the outside of the connecting frame 206 and above the base 1.

[0026] A connecting rod 207 is fixedly connected to one end of the connecting frame 206. The linkage plate 208 is "L" shaped. A cooperating spring 209 is fixedly connected between one side of the linkage plate 208 and the connecting rod 207. By setting the cooperating spring 209, the movement trajectory of the linkage plate 208 driving the clamping head 205 is stable, while avoiding rigid clamping of the lithium battery.

[0027] It should be further explained that in actual use, the lithium battery is placed on the base 1 and positioned between the two sets of clamping heads 205. The position of the limiting rod 204 is adjusted according to the specifications of the lithium battery to be clamped. Then, the electric push rod 201 is activated, causing it to move the two sets of linkage rods 202 within the sliding frame 102 via the connector 210 and hinge plate 211. The movement of the linkage rods 202 drives the linkage plate 208 via the connector 206, which in turn causes the linkage plate 208 to move the clamping heads 205. When the lithium battery is clamped, the clamping head 205 clamps and fixes it. As the linkage rod 202 moves, the limiting plug 204 contacts the pressure switch on the sliding frame 102, and the electric push rod 201 is de-energized and stops working. This effectively clamps and fixes the lithium battery while avoiding excessive clamping force that could damage the lithium battery itself. Furthermore, the limiting plug 204 and the limiting hole 203 make it easy to adjust the clamping of lithium batteries of different specifications, making it highly applicable.
