Composite pressing clamp of panel-type electrode bracket for COMMB-LED (chip on mirror metal board-light emitting diode)

Abstract

The invention discloses a composite pressing clamp of a panel-type electrode bracket for a COMMB-LED (chip on mirror metal board-light emitting diode), wherein the connection of the bearing platform of the clamp and a clamp body made of engineering plastics by injection molding is actuation of a magnetic vertical direction (Z direction) and actuation of a transverse direction (X direction), and the composite pressing clamp can achieve online transverse thrust and is convenient to dismantle. The clamp body is attached to the limiting block clamp of the bearing platform and the bottom plate flange of the clamp without clearance due to magnetic force, so higher position precision is achieved. Each single body integrated by adopting the panel-type electrode bracket for the COMMB-LED respectively and independently finishes single-body self-lock pressing arrangement in a height direction by a mechanical spring, and the composite pressing clamp is processed by insulated interlayers of electrodes outwards led at two sides of the panel-type electrode bracket for the COMMB-LED and achieved on the bearing platform of the panel-type electrode bracket for the COMMB-LED by a glue injecting mode, so the manufacture and use efficiencies of the clamp are greatly improved.

[0002] At present, in the packaging and processing process of LED electrode brackets, in order to adapt to the structural characteristics of the electrode brackets in automated production and greatly improve production efficiency, the LED electrode brackets must be assembled and clamped in a square array before subsequent processing (generally once) The clamping capacity is 100 to 200), as far as the existing clamping fixture is concerned, there are generally three clamping forms, one is the straight push column type, and the horizontal push plate with self-locking device is used for longitudinal push Finally, use the turning handle to self-lock to complete the lateral clamping of the LED in-line electrode bracket. Another method is to use the side vertical indentation method to complete the lateral clamping of the LED in-line electrode bracket. For the former clamp Due to the impact of the vibration load and the large lateral pressure during the processing, it is easy to cause the pressing steel ball of the self-locking mechanism of the handle to wear out and fail

Although the latter type is pressed in sideways by the side cutter, the wear problem has been fully solved, but the clamping force and clamping accuracy are not high when the bracket is further processed by using the fixture, and the realization effect is not ideal. .There is also a fixture suitable for the external electrode with insulating separation beads is a flexible lead LED in-line bracket, the fixture itself is light in weight, and the fixture itself can have a long service life

The above three kinds of fixtures are respectively used for the current LAMP and SMD and the external electrodes with insulating separation beads are flexible lead LED in-line brackets. They are used in the "LED Surface Light Source" patent number 2010205438630 patent publication authorized by the China Patent Office No.: CN100392880C; Among them, COMMB-LED surface-type electrode bracket, automatic large-scale industrial production requires its own poor axial strength, low precision of single cross-section size, and high reflective surface on the chip carrying surface. For the redesign of the integrated fixture, it is necessary to carry out self-locking and flattening in the height direction independently for each monomer integrated in the COMMB-LED surface electrode bracket, and to perform reliable locking when pressing laterally along the length direction of the fixture. Only by achieving high position accuracy can the follow-up process be carried out smoothly. Therefore, the three commonly used fixtures currently have defects, and they cannot meet the processing requirements of the COMMB-LED surface electrode bracket and need to be improved.
