Description

Technical Field

[0001] The invention relates to the technical field of linear module processing equipment, in particular to optical axis pre-pressing equipment and a processing method. Background Art

[0002] The linear module usually includes a fixed profile and an optical axis fixedly installed in the fixed profile. The fixed profile is provided with a slot structure. After the optical axis passes through the slot structure, the stamping equipment drives the stamping head to move. When the stamping head stamps, the fixed profile is deformed, and some point-shaped structures are stamped out on the fixed profile. The deformed fixed profile will be fixed to the optical axis.

[0003] There are many structures for fixing profiles. Existing customers provide Figure 1 The schematic diagram of the linear module fixed profile, optical axis and core rod after assembly is shown. The cavity structure is located below the slot where the optical axis passes. During processing, the core rod needs to be inserted into this cavity structure ( Figure 1 The mesh part in the mold) can avoid deformation of the cavity structure during stamping, thereby ensuring product quality.

[0004] However, since the fixed profile of the linear module is usually long, steps such as assembling the optical axis, inserting the core rod and pulling out the core rod are generally performed with the fixed profile placed horizontally. Assembling the optical axis, inserting the core rod and pulling out the core rod requires reserving more space for the movement of the optical axis and the core rod, resulting in the length of the processing equipment being at least twice the length of the fixed profile.
