Abstract
The utility model relates to a pressing claw device of a lead frame, comprising a bracket, wherein the bracket comprises a vertical connecting part; the upper end of the vertical connecting part is connected with an upper platform and a lower platform which are arranged in parallel; and the upper platform is detachably connected with 2-3 pressing claws. The pressing claw device has the advantages that by adoption of the scheme, the stressing of all the parts of the lead frame is uniform by adjustment, and the weldability and the production quality are greatly improved.
Description
Technical field
The utility model relates to a kind of lead frame press claw device, belongs to the electric elements technical field of processing equipment.
Background technology
At present, in the lead frame welding process, mostly adopt paw to compress, present paw is structure as a whole, because lead frame needs bending in process of production, the height of each point of lead frame is inconsistent after the bending, when compressing lead frame with traditional paw, each position discontinuity of lead frame occurs that bonding wire is insecure, the rosin joint phenomenon, cause occurring waste product, reduced the quality of production.
The utility model content
Problem to be solved in the utility model provides a kind of lead frame press claw device that each ministries and commissions of lead frame are stressed evenly, improve solderability and the quality of production that makes.
In order to address the above problem, the utility model by the following technical solutions:
A kind of lead frame press claw device comprises support, and described support comprises vertical connecting portion, and vertically the upper end of connecting portion is connected with upper mounting plate and lower platform, and upper mounting plate and lower platform be arranged in parallel, are removably connected with 2-3 paw on the described upper mounting plate.
Below be the utility model for further improvement of these options:
Described paw comprises paw connecting portion and pawl point, has the first slotted hole on the described paw connecting portion, is provided with adjustment screw in the first slotted hole, and described adjustment screw is threaded with upper mounting plate.Can regulate by adjustment screw the front and back position of paw, and the position, the left and right sides of fine-tuning paw.
Further improve: the position near paw connecting portion rear end on the described upper mounting plate has through hole, position corresponding with the through hole on the upper mounting plate on the lower platform has deep gouge, between upper mounting plate and lower platform, regulating spring is installed, the up and down two ends of regulating spring lay respectively in through hole and the deep gouge, are provided with the jackscrew that can hold out against regulating spring with the corresponding position of deep gouge on lower platform.Can finely tune by regulating regulating spring the compression degree of pawl point to the pressure of paw connecting portion.
The utility model adopts such scheme, can by regulating, so that each position of lead frame is stressed evenly, greatly improve solderability and the quality of production.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: the 1-support; The 2-upper mounting plate; 3-paw connecting portion; 4-pawl point; 5-the first slotted hole; The 6-adjustment screw; The 7-regulating spring; 8-the second slotted hole; The vertical connecting portion of 9-; The 10-lower platform.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of lead frame press claw device comprises support 1, and described support 1 comprises vertical connecting portion 9, vertically has the second slotted hole 8 that is used for fixing support on the connecting portion 9, and vertically the upper end of connecting portion 9 is connected with upper mounting plate 2 and lower platform 10.Upper mounting plate 2 and lower platform 10 be arranged in parallel, be removably connected with 2-3 paw on the described upper mounting plate 2, described paw comprises paw connecting portion 3 and pawl point 4, have the first slotted hole 5 on the described paw connecting portion 3, in the first slotted hole 5, be provided with adjustment screw 6, described adjustment screw 6 is threaded with upper mounting plate 2, can regulate by adjustment screw 6 front and back position of paw, and the position, the left and right sides of fine-tuning paw.
Position near paw connecting portion 3 rear ends on the described upper mounting plate 2 has through hole, position corresponding with the through hole on the upper mounting plate 2 on the lower platform 10 has deep gouge, between upper mounting plate 2 and lower platform 10, regulating spring 7 is installed, the up and down two ends of regulating spring 7 lay respectively in through hole and the deep gouge, are provided with the jackscrew 11 that can hold out against regulating spring 7 with the corresponding position of deep gouge on lower platform 10.
Can finely tune by the pressure of regulating 7 pairs of paw connecting portions 3 of regulating spring the compression degree of pawl point 4.
The utility model adopts such scheme, can by regulating, so that each position of lead frame is stressed evenly, greatly improve solderability and the quality of production.
