[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.
[0026] A flexible etching support fixture provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.
[0027] Example 1:
[0028] Combine Figure 1-4 As shown, the utility model provides a flexible etching support fixture, including: a bracket 100, a clamping assembly 200, and a balancing assembly 300; the clamping assembly 200 includes a plurality of fixed clamps 201 arranged and fixedly installed on one side of the bracket 100, an outer clamping block 202 fixedly installed at both ends of the outer side of the fixed clamp 201, an inner clamping block 203 fixedly installed at both ends of the inner side of the fixed clamp 201, and a reference block 204 fixedly installed at the center of the inner end of the fixed clamp 201; a sliding portion 205 and an outer pressing portion 206 are respectively provided on the outer side and the inner side of the outer clamping block 202, an extrusion port 207 is also provided in the center of the outer pressing portion 206, an extrusion hole 208 is also provided in the middle part of the inner clamping block 203, and a reference edge 209 is also provided at the front end of the reference block 204, and the outer clamping block 202 and the inner clamping block 203 are both made of corrosion-resistant rubber.
[0029] Specifically, flexible etching in the field of electronic manufacturing usually refers to flexible circuit board etching technology, which is mainly used to remove unnecessary metal layers on circuit boards, thereby forming a predetermined circuit pattern on flexible materials. The flexible etching support fixture is mainly a fixture for clamping and fixing multiple sets of circuit boards. The outer clamping blocks 202 and inner clamping blocks 203 are symmetrically installed on both sides of the fixing clamp 201 on this bracket 100. They can respectively press and clamp the inner and outer ends of the end faces of both sides of the circuit board through the outer pressing parts 206, extrusion ports 207 and extrusion holes 208 on their inner sides after extrusion deformation, thereby ensuring stable support during flexible etching of the circuit board. The outer clamping blocks 202 and inner clamping blocks 203 are symmetrically installed on both sides of the fixing clamp 201 on this bracket 100. 02 The sliding portion 205 arranged on the outer side of the inner end is an outward-opening structure, which is mainly used to ensure the quick insertion of the circuit board during clamping. The outer clamping portions 206 formed on both sides of the extrusion port 207 can be clamped at two points to ensure the clamping strength of the outer side of the circuit board. The extrusion hole 208 opened at the center of the inner clamping block 203 is mainly used to press the inner end surface of the inner clamping block 203 to the outer end of the circuit board during the extrusion of the inner clamping block 203, thereby ensuring a good clamping effect. The reference edge 209 set at the front end of the inner reference block 204 of the fixing clamp 201 is mainly used to ensure the positioning of the inner clamping position of the circuit board, thereby ensuring the neatness of the arrangement of the circuit boards after clamping.
[0030] Example 2:
[0031] Combine Figure 3 and Figure 5 As shown, on the basis of Example 1, the balancing assembly 300 includes a slide groove 301 provided in the reference block 204, balancing clamps 302 movably installed on both sides of the slide groove 301, and an outer rolled portion 303 is provided on the upper front end of the balancing clamp 302. Circular holes 304 are provided at the upper and lower ends of the inner side of the balancing clamp 302, and fixed columns 305 are movably installed in the circular holes 304, and both ends of the fixed columns 305 are fixed in the slide groove 301. Springs 306 are movably installed on the outer ends of the fixed columns 305 outside the balancing clamp 302.
[0032] Specifically, the balancing clamps 302 installed on both sides of the upper end of the fixing clamp 201 can also be used to horizontally press and clamp the two sides of the circuit board during circuit board clamping, thereby ensuring the stability and balance of the circuit board after clamping. The outer rolled portion 303 provided on the outer end of the balancing clamp 302 is mainly used to facilitate the insertion of the circuit board clamping. The springs 306 installed on the outer ends of the fixed columns 305 on both sides of the balancing clamp 302 are mainly used for pressing the balancing clamp 302 when it is stretched, thereby ensuring the balance of the circuit board clamped by its inner end. The outer clamping blocks 202 and the inner clamping blocks 203 that can be pressed and deformed on both sides of the inner side of the fixing clamp 201 and the balancing clamp 302 that can be pressed and opened on both sides of the upper end of the fixing clamp 201 also make this clamp adaptable to the clamping of circuit boards of different thicknesses for flexible etching, thereby improving the applicability of this clamp.
[0033] The working principle and use process of this utility model:
[0034] When clamping the circuit board, first insert the circuit board between the sliding part 205 and the outer rolled part 303 on the outside of the fixing clamp 201, and continue to pull the circuit board inward after the circuit board is inserted, so that the circuit board squeezes the extrusion opening 207 and the extrusion hole 208 in the outer clamping block 202 and the inner clamping block 203 in turn, so as to clamp the end faces of both ends between the outer clamping blocks 202 and the inner clamping blocks 203 on both sides. After the circuit board is inserted to the front of the reference edge 209 at the inner end of the fixing clamp 201, its clamping position will be positioned, and the upper two sides of the circuit board will also be clamped between the balance clamps 302 at the inner ends of the outer rolled parts 303 on both sides, so as to ensure the overall levelness of the circuit board after clamping. Finally, after multiple groups of circuit boards are clamped in the fixing clamp 201 on the bracket 100 in turn, the circuit board clamping and fixing are completed.
[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
