DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-Figure 4 As shown, a safety shield for spot welding operations in the production of lithium-ion battery packs comprises a transparent baffle 1, the tops of the front and rear ends of the transparent baffle 1 are fixedly connected with fixed blocks 11, the bottom of the fixed block 11 is fixedly connected with a limiting mechanism 2, the front and rear parts of the right end of the transparent baffle 1 are fixedly connected with an extension mechanism 3, the front part of the right end of the transparent baffle 1 is fixedly connected with a cleaning mechanism 4, the limiting mechanism 2 comprises two fixing plates 21, one end of the fixing plate 21 is fixedly connected to the bottom of the fixing block 11, the extension mechanism 3 comprises two extension rods 32, the left end of the extension rod 32 is fixedly connected to the right end of the transparent baffle 1, and the cleaning mechanism 4 comprises a mounting plate 41, the left end of the mounting plate 41 is fixedly connected to the front part of the right end of the transparent baffle 1.

[0028] The height of the device is changed by extending the mechanism 3 so that the device can adapt to lithium-ion battery packs of different heights. The transparent baffle 1 after the angle is changed can be limited by the limiting mechanism 2 so that the transparent baffle 1 can no longer rotate. During subsequent work, the waste generated during work can be collected by the cleaning mechanism 4 to facilitate subsequent cleaning.

[0029] like Figure 2 , Figure 3 As shown, the inner wall of the fixed plate 21 is slidably connected with a pull rod 22, the top of the pull rod 22 is fixedly connected with a connecting plate 24, the outer wall of the pull rod 22 is movably sleeved with a spring 23, the top of the spring 23 is fixedly connected to the bottom end of the connecting plate 24, the top of the connecting plate 24 is fixedly connected with a limiting block 25, and the inner wall of the limiting block 25 is clamped with a clamping block 26.

[0030] By pressing the connecting plate 24, the connecting plate 24 drives the limit block 25 to move downward, and at the same time, the pull rod 22 slides on the inner wall of the fixed plate 21, driving the spring 23 to contract, so that the inner wall of the limit block 25 is no longer engaged with the outer wall of the clamping block 26, thereby canceling the limit of the limit block 25 on the clamping block 26, and then the transparent baffle 1 can be rotated.

[0031] like Figure 2 , Figure 3 As shown, a rotating shaft 27 is fixedly connected to the axis of the clamping block 26 , and the outer wall of the rotating shaft 27 is rotatably connected to the fixing block 11 and the top of the transparent baffle 1 .

[0032] When the transparent baffle 1 is rotated, the rotating shaft 27 is driven to rotate synchronously, and the rotating shaft 27 drives the clamping block 26 to rotate synchronously. When the transparent baffle 1 is rotated to a suitable angle, the rotation of the transparent baffle 1 can be stopped, and then the connecting plate 24 is loosened to make the inner wall of the limit block 25 engage with the outer wall of the clamping block 26 again, thereby fixing the transparent baffle 1 after the angle is changed, thereby achieving a limiting effect.

[0033] like Figure 2 , Figure 4 , Figure 5 As shown, the outer wall of the extension rod 32 is movably sleeved with the fixed rod 31, the extension rod 32 has a T-shaped appearance, a slot 33 is provided on the outer wall of the extension rod 32, a sleeve block 34 is fixedly connected to the top of one end of the fixed rod 31, the inner wall of the sleeve block 34 is movably sleeved with a limit rod 35, the outer wall of the limit rod 35 is plugged into the inner wall of the slot 33, the outer wall of the limit rod 35 is fixedly connected to a limit plate 36, the outer wall of the limit rod 35 is movably sleeved with a limit spring 37, and the outer wall of the limit spring 37 is slidably connected to the inner cavity of the sleeve block 34.

[0034] By pulling the limit rod 35, the limit rod 35 drives the limit plate 36 to slide on the inner wall of the sleeve block 34, so that the limit spring 37 contracts, and at the same time the outer wall of the limit rod 35 is no longer plugged into the inner wall of the slot 33, then the extension rod 32 can be pulled to slide on the inner wall of the fixed rod 31, when the distance is appropriate, stop pulling the extension rod 32, then release the limit rod 35, so that the outer wall of the limit rod 35 is plugged into the inner wall of the slot 33 again, thereby limiting the position and making the extension rod 32 unable to extend any further, thereby changing the height of the transparent baffle 1, achieving the effect of changing the height.

[0035] like Figure 2 , Figure 6 As shown, a blower 42 is fixedly connected to the top of the front end of the mounting plate 41, a dust suction port 43 is fixedly connected to the input end of the blower 42, an outer wall of the dust suction port 43 is fixedly connected to the top of the mounting plate 41, a dust outlet 44 is fixedly connected to the output end of the blower 42, a support plate 45 is fixedly connected to the bottom of the front end of the mounting plate 41, a collection box 46 is fixedly connected to the top of the support plate 45, and the collection box 46 is located below the dust outlet 44.

[0036] By turning on the blower 42, the waste chips generated during the welding process are sucked away by the dust suction port 43 and transported to the dust outlet 44, and then fall into the collection box 46 from the dust outlet 44, so that the waste chips are collected for subsequent cleaning.

[0037] The working principle of the utility model is as follows: when in use, the lithium-ion battery pack that needs to be welded is placed on the designated workbench, and then the device is fixed on the workbench so that the transparent baffle 1 blocks the lithium-ion battery pack, and at the same time, the device is raised according to the height of the lithium-ion battery pack, and the limit rod 35 is pulled, so that the limit rod 35 drives the limit plate 36 to slide on the inner wall of the sleeve block 34, so that the limit spring 37 contracts, and at the same time, the outer wall of the limit rod 35 is no longer plugged into the inner wall of the slot 33, and then the extension rod 32 can be pulled to make the extension rod 32 slide on the inner wall of the fixed rod 31. When the distance is appropriate, stop pulling the extension rod 32, and then release the limit rod 35, so that the outer wall of the limit rod 35 is plugged into the inner wall of the slot 33 again, thereby limiting the position and making the extension rod 32 unable to extend any further, thereby changing the height of the transparent baffle 1, which has the effect of changing the height, and then the electric welding work can be started, and according to the needs of the work, The angle of the transparent baffle 1 can be adjusted to make the work more convenient. By pressing the connecting plate 24, the connecting plate 24 drives the limit block 25 to move downward, and at the same time the pull rod 22 slides on the inner wall of the fixing plate 21, driving the spring 23 to contract, thereby making the inner wall of the limit block 25 no longer engage with the outer wall of the block 26. After that, the transparent baffle 1 can be rotated to make the transparent baffle 1 rotate around the rotating shaft 27. When the transparent baffle 1 is rotated to a suitable angle, the rotation of the transparent baffle 1 can be stopped, and the connecting plate 24 can be loosened at the same time, so that the inner wall of the limit block 25 is engaged with the outer wall of the block 26 again, thereby fixing the transparent baffle 1 after the angle is changed, which plays a limiting effect. Later, when working, the blower 42 can be turned on, and the dust suction port 43 can suck away the waste chips generated during the electric welding process and transport them to the dust outlet 44, and the dust outlet 44 falls into the collection box 46, so that the waste chips are collected, which is convenient for subsequent cleaning, thereby greatly improving the use experience.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
