Description
Technical Field
The utility model relates to a battery manufacturing technology field, especially a battery module welding jig monomer pressure head.
Background
The welding fixture is generally used in the welding process of the electric core pole and the bus piece of the power battery module section to compress the bus piece to achieve the laminating effect of the pole and the bus piece, namely, the compression and lamination of one pole and one bus piece are realized by one pressure head. There are two designs of indenter in common use today: 1. the pressure head is designed in a single-layer mode, shielding gas in the welding process is blown from the upper portion of the pressure head, and welding slag generated in the welding process is sucked away by the copper pipe above the pressure head under the negative pressure. The design has poor actual effect because the distance between the blown shielding gas and the sucked welding slag and the surface of the welding butt is far; 2. the double-layer design pressure head, the shielding gas blows from the gap between the inner layer and the outer layer, and dust is absorbed above the pressure head in the welding process. The design reduces the distance of blowing shielding gas, and the welding seam protection is improved to a certain extent, but the design has the defects that the inner layer and the outer layer of design gaps are easily filled with welding slag, a pressure head vibrates before the next welding, the welding slag falls on a connecting piece to be welded, and welding splashing and explosion points are caused at a high probability. Therefore, it is necessary to provide a pressure head with an integrated design, which integrates the functions of blowing shielding gas and sucking welding slag, so that the shielding gas is directly blown to the surface of the splints from the bottom of the pressure head, and the welding slag can be sucked away in the first time.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a single pressure head of a welding fixture for a battery module, which is characterized by comprising a pressure head main body, a pressing mechanism, an air inlet and a dust suction pipeline joint; the pressure head main body accommodates the pressing mechanism, is provided with a protective gas channel and is connected with the gas inlet and the dust collection pipeline joint; the pressing mechanism comprises a guide pillar, a fixing block and a spring.
The pressure head main body is further provided with an air distribution block mounting opening, and an air distribution block is mounted on the pressure head main body.
Wherein, divide the gas piece to pass through bolted connection to the pressure head main part, play the guard gas guide effect.
The pressure head main body and the gas distribution block are made of chromium, zirconium and copper.
The utility model provides a battery module welding jig monomer pressure head, the shielding gas export is close apart from the face of weld distance, plays better guard action. The welding dust absorption has bigger suction effect at pressure head main part side opening, ensures to pass through outside dust collecting equipment negative pressure with welding process smoke and dust and plasma cloud and discharges. The air outlet of the air distribution block can better play a role in guiding the protective air. The main body and the gas distributing block of the pressure head are made of chromium zirconium copper, and the material has good electrical conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, crack resistance and high softening temperature. The welding rod can be effectively compressed without deformation, can not be softened in a high-temperature welding environment, has the characteristics of wear resistance and explosion resistance, and can effectively reduce the adhesion of welding slag. The monomer pressure head designs as an organic whole, adopts the pressure head body as main part frame construction, and the inlet channel of input shielding gas and the bleed passage of cleaing away the welding slag are all integrated on the pressure head body, and easy maintenance changes swiftly.

Detailed Description
The present invention will be further described with reference to the following embodiments, which are only used for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1-4, the single pressure head of the battery module welding fixture of the present invention comprises a pressure head main body 1, a pressing mechanism 2, an air inlet 3 and a dust suction pipe joint 4. The air inlet 3 is connected with an external protective gas source to prevent the high-temperature welding pool from being oxidized and prevent welding seam fish scale lines from being blown out. The dust collection pipe joint 4 is connected with an external dust removal air pipe and used for pumping out smoke dust and plasma cloud generated by welding. The pressure head main body 1 accommodates a pressing mechanism 2, is provided with a protective air passage 5, and connects an air inlet 3 and a dust suction pipe joint 4. The indenter body 1 flattens the bar piece and the pole, and prevents poor welding due to a gap between the bar piece and the pole. The pressure head main body 1 is also provided with a gas distribution block mounting port 6 for mounting a gas distribution block 7. The air distribution block 7 is connected to the pressure head main body 1 through bolts and plays a role in guiding protective air. The pressing mechanism 2 comprises a guide pillar 9, a fixing block 10 and a spring 8, and the spring 8 is compressed through external force, so that the pressure head main body 1 provides pressure for a welding workpiece.
In welding process, make module jacking or pressure head push down through external acting force, make four group's springs in the pressure head hold-down mechanism reach rated compression, spring compression load effect pressure head makes piece and utmost point post laminating, avoids leading to harmfulness such as rosin joint because of the clearance problem. The protective gas is led out through the protective gas inlet head, the pressure head main body internal channel and the gas distribution block before welding, so that the pressure head bottom area is filled with inert gas, and the high-temperature molten pool is prevented from being oxidized in the condensation process. The dust collection joint is connected with an external negative pressure device, and splashes, smoke and plasma clouds generated in the welding process are discharged nearby through a dust collection pipeline, so that the interference of the smoke and the plasma clouds and the like on a light path is ensured, and the welding quality is ensured.
While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
