Description

TECHNICAL FIELD

[0001] The utility model relates to a carrying clamp jaw technical field especially with detection function's welding line carrying clamp jaw. BACKGROUND

[0002] In the seat slide rail welding production process, the traditional carrying mode often relies on manual operation or relatively simple mechanical device, which has many disadvantages. On the one hand, manual carrying of seat slide rail is low in efficiency, and when the welded seat slide rail is transferred to the next process, a lot of time and manpower are consumed, which is difficult to meet the growing production demand and seriously restricts the overall efficiency improvement of seat slide rail welding production.

[0003] Some existing grabbing devices can also transfer seat slide rails from one station to another, however, since most of the parts are installed below the seat slide rail, during carrying, the parts may still remain in the station due to incomplete welding of the seat slide rail and the parts, resulting in unqualified seat slide rails being transferred to the next process, increasing the subsequent product quality risk and production error correction cost.

[0004] At the same time, when grabbing the seat slide rail, due to the cooperation problem of the seat slide rail and the positioning pin on the production line, the positioning pin often gets stuck in the positioning hole of the seat slide rail, causing the seat slide rail to be unable to be smoothly clamped, which not only affects the normal production process, but also may cause damage to the equipment and seat slide rail.

[0005] Therefore, it is necessary to design a welding line carrying clamp jaw with detection function to solve the above problems. UTILITY MODEL CONTENTS
