Composite pressing clamp for LED direct plug-in soft down-lead bracket

Abstract

The invention relates to a composite pressing clamp for an LED direct plug-in soft down-lead bracket. A clamp body is formed by processing high strength engineering plastics through injection molding, thereby leading the integral weight of the clamp to be lighter; by using the method of adjusting the eccentricity of an eccentric sleeve screw cap, higher requirement on the positional precision of a base hole supporting an eccentric pipe is met; a hexagonal rotatable handle on a shaft of an inner eccentric pipe is rotated, and under the action of strong external force, the inner eccentric pipe drives the height direction of a T-shaped plate to move downwards along the vertical direction; during imposed deformation, a conjoined bracket which bears an LED direct plug-in bracket provided with epoxy resin cladding insulating separating balls is horizontally pressed to be straight and simultaneously accomplishes the self-locking pressing leveling along the height direction; and an end face thrusting lock screw accomplishes the operation of longitudinally, spirally and forcefully pushing a horizontal pushing plate, thereby leading an external electrode provided with the epoxy resin cladding insulating separating balls to be processed on a matrix formed by the gapless overlapping of the collected LED direct plug-in soft down-lead brackets, and greatly improving the subsequent production and the use efficiency.

Description

Technical field: [0001] The invention relates to a pressing fixture used when LED in-line electrode brackets need to be assembled and clamped in the process of LED processing, in particular to a composite pressing fixture for LED in-line electrode brackets whose external electrodes are flexible leads. Tighten the clamp. Background technique: [0002] At present, in the process of processing LED in-line electrode brackets, in order to cooperate with automated production and greatly improve production efficiency, the LED in-line electrode brackets must be assembled and clamped in a square array before subsequent processing (generally, the amount of clamping at one time) 500 to 600), as far as the existing clamping fixtures are concerned, there are generally two clamping forms, one is the straight push column type, and the horizontal push plate with a self-locking device is used for longitudinal pushing.

[0002] At present, in the process of processing LED in-line electrode brackets, in order to cooperate with automated production and greatly improve production efficiency, the LED in-line electrode brackets must be assembled and clamped in a square array before subsequent processing (generally, the amount of clamping at one time) 500 to 600), as far as the existing clamping fixtures are concerned, there are generally two clamping forms, one is the straight push column type, and the horizontal push plate with a self-locking device is used for longitudinal pushing. After the turning handle is self-locked, the lateral clamping of the LED in-line electrode bracket is completed. Another method is to complete the lateral clamping of the LED in-line electrode bracket by using the side vertical indentation method. For the former clamp, due to the processing process In the middle, affected by the vibration load, coupled with the large lateral pressure, it is easy to cause the pressing steel ball of the self-locking mechanism of the turning handle to wear, especially when the LED in-line electrode bracket is to be further processed by a fixture. Easy to cause clamping failure

Although the wear problem of the latter type has been fully resolved after the side cutter is pressed in sideways, the clamping force and clamping accuracy are not ideal when the bracket is further processed by the clamp, and the Both of the above-mentioned fixtures are made of high-strength aluminum alloy, which makes the weight of the fixture heavy and the manufacturing cost is high. The dynamic load inertia of the loading table on the subsequent processing machinery is relatively large. "Light Emitting Diode" Patent No. 200510022149.0 applied by the Patent Office, Patent Publication No.: CN100392880C; Automated large-scale industrial production requires the use of a conjoined frame (usually soft plastic with high self-lubricating effect) that is used to connect the LED in-line electrode bracket. Type LED brackets are processed in series after the overall square array is integrated, so the one-piece bracket must be self-locked and flattened in the height direction, and reliable locking must be performed when pressing the sideways along the length of the fixture. Only in this way can the follow-up process be carried out smoothly. Therefore, the two commonly used fixtures at present have defects and cannot meet the processing requirements of the LED in-line electrode holder with the outer lead electrode of the insulating separation bead as a flexible lead wire and needs to be improved.
