3results about How to "Prevent affecting the welding effect" patented technology

An in-die laser welding structure comprises an upper die base, a lower die base, a discharging plate and a material belt, the upper die base and the discharging plate are fixedly connected through a connecting plate, a fixing plate is arranged at the upper end of the lower die base, a laser welding head is obliquely arranged in the fixing plate, the material belt is fixedly arranged at the upper end of the fixing plate, the upper die base comprises a male die, and a female die is fixedly arranged in the fixing plate. The upper die base drives the male die to punch a material belt, a product is punched from the material belt into the female die, a welding groove is formed in the product, the laser welding head is aligned with the welding groove to weld the product, the laser welding head is arranged in the lower die base, laser welding is directly completed before discharging after the lower die base completes punching, and high precision and consistency of the welded product are guaranteed. A laser welding head is obliquely arranged in the fixing plate, so that the welding space is sufficient, and heat accumulation can be prevented from affecting the welding effect; and the original clamping station and the original welding station are omitted, so that the production cost is greatly reduced.

This utility model discloses a planar small-part welding positioning platform, including a base, a negative pressure seat, a planar small-part positioning seat, and a product positioning seat. The negative pressure seat includes a mounting plate, a support plate, and multiple negative pressure suction heads. The mounting plate is disposed on the base, and the support plate is disposed on the mounting plate. The upper surface of the support plate is provided with multiple protrusions, and the upper surface of the multiple protrusions is provided with positioning mounting holes extending into the support plate. The multiple negative pressure suction heads are respectively disposed in the multiple positioning mounting holes for suctioning the product. The planar small-part positioning seat is disposed on the mounting plate for positioning and fixing the small part. The product positioning seat is disposed on the mounting plate for positioning the product, so that when the product is adsorbed onto the support plate, the planar small-part positioning seat is located within the welding area on the product. The planar small-part welding positioning platform provided by this utility model has a simple structure, is easy to use, and can position and fix small parts, preventing the small parts from shifting during the welding process and affecting the welding effect.

This utility model relates to the field of battery pack welding, specifically a lithium battery pack welding auxiliary positioning device, including a support plate, a processing table, a clamping mechanism, a pressing mechanism, and a moving mechanism. The clamping mechanism includes a mounting plate, a first clamping assembly, a second clamping assembly, two first clamping plates, and two second clamping plates. The pressing mechanism includes two pressing blocks, two positioning assemblies, and two resetting assemblies. The moving mechanism includes a movable block, a lead screw slide, and a lifting assembly. A controller controls a first motor to rotate, which in turn drives a first rotating rod to rotate, causing the two first clamping plates to clamp and fix the two sides of the lithium battery pack, keeping the lithium battery pack aligned front to back for easy placement of welding pieces. The controller then controls a second motor to rotate, causing the two second clamping plates to move on the processing table and clamp the other two sides of the lithium battery pack. Together with the first clamping assemblies, the device can position and clamp the lithium battery pack on all four sides.
