Description

Technical Field

[0001] This utility model relates to the field of battery explosion-proof sheet technology, specifically a precision positioning and assembly device for battery explosion-proof sheets. Background Technology

[0002] Battery explosion protectors are important devices used to protect batteries. They can prevent batteries from exploding or catching fire in cases of overcharging, over-discharging, short circuits, or external damage. Battery explosion protectors are classified into categories such as PTC explosion protectors, magnetic reed explosion protectors, and electronic explosion protectors.

[0003] After production, battery explosion-proof sheets often need to be fixed to the battery by a clamping device, and then the explosion-proof sheet is welded to the outside of the battery by a robotic arm. However, the existing clamping devices can only limit the battery position and cannot position and assemble the explosion-proof sheet, which makes it impossible to accurately place the explosion-proof sheet in the required position on the outside of the battery. Therefore, a precision positioning and assembly device for battery explosion-proof sheets is proposed to solve the above-mentioned problems. Utility Model Content

However, the existing clamping device can only limit the battery and cannot position and assemble the explosion-proof sheet, resulting in the explosion-proof sheet not being able to be accurately placed in the required position on the outside of the battery.

[0027] In the embodiments, by Figure 1-4 The present invention provides a precision positioning and assembly device for a battery explosion-proof sheet. The present invention includes a housing 1, a dual-axis motor 2 fixedly connected inside the housing 1, threaded horizontal rods 3 fixedly connected to the output ends on both sides of the dual-axis motor 2, a threaded vertical rod 4 rotatably connected inside the housing 1, movable blocks 5 threadedly connected to the outer sides of the two threaded horizontal rods 3 and the threaded vertical rod 4, clamping blocks 6 fixedly connected to the front of the two top movable blocks 5, a push block 7 fixedly connected to the front of the bottom movable block 5, and an assembly mechanism 8 fixedly connected to the front of the housing 1.

[0028] A handle 9 is fixedly connected to the bottom of the threaded vertical rod 4, and the handle 9 is located at the bottom of the outer casing 1;

[0029] The threaded vertical rod 4 can be rotated by the throttle 9;

[0030] The assembly mechanism 8 includes a cylinder 801, a locking block 802 is fixedly connected to the bottom of the cylinder 801, an explosion-proof disc body 803 is locked to the bottom of the locking block 802, and a top block 804 is fixedly connected to the front of the outer shell 1.

[0031] The cylinder 801 enables the locking block 802 to extend and retract;

[0032] The top block 804 has an internal mounting hole 10, which is compatible with the locking block 802;

[0033] The mounting hole 10 allows the card block 802 to extend and retract to the outside of the battery;

[0034] The interior of the outer casing 1 has two transverse sliding slots 11, which are adapted to the two moving blocks 5 at the top;

[0035] The two moving blocks 5 at the top can move laterally via the transverse sliding groove 11;

[0036] The interior of the outer casing 1 is provided with a vertical moving groove 12, which is adapted to the moving block 5 at the bottom;

[0037] The vertical moving slot 12 enables the bottom moving block 5 to move vertically.

[0038] Working principle:

[0039] Step 1: Place the battery on top of the casing 1, then start the dual-axis motor 2. The output ends on both sides of the dual-axis motor 2 drive the two threaded crossbars 3 to rotate. The rotation of the two threaded crossbars 3 drives the outer moving blocks 5 to move to opposite sides, thereby causing the two top moving blocks 5 to drive the two clamping blocks 6 to clamp the battery. When the battery is in a vertical position, the dual-axis motor 2 drives the two clamping blocks 6 to move to opposite sides, thereby creating a gap between the two clamping blocks 6 and the battery. Then turn the handle 9, causing the handle 9 to drive the threaded vertical rod 4 to rotate. The rotation of the threaded vertical rod 4 drives the bottom moving block 5 to move upward, thereby allowing the bottom moving block 5 to drive the push block 7 to move upward and push the battery upward, thereby moving the battery to the top block 804 for limiting. Then, the dual-axis motor 2 drives the two clamping blocks 6 to clamp the battery on both sides, thereby limiting the battery.

[0040] Step 2: Connect the explosion-proof plate body 803 to the locking block 802, start the cylinder 801, and make the cylinder 801 drive the locking block 802 and the explosion-proof plate body 803 to move to the outside of the battery through the mounting hole 10 inside the top block 804, and then weld them by the robot arm.
