Description

Technical Field

[0001] This utility model relates to a floating etchant suction knife, and more particularly to a etchant suction knife that can maintain its horizontality on its own. Background Technology

[0002] The widely used horizontal PCB etching production line is simple to operate and has a large capacity. This type of production line sprays etching solution on both the top and bottom surfaces of the PCB board. During the etching process, because the etching solution in the middle of the upper surface of the PCB board flows away more slowly than the etching solution at the edges, some of the reacted etching solution accumulates in the middle. The amount of fresh etching solution replenished is reduced, and the etching speed is correspondingly slower. This is what the industry calls the pool effect. In order to solve the pool effect, etching solution suction blades are usually installed close to the surface of the PCB board to remove the reacted etching solution in real time, thereby making the etching rate in the middle and the edges of the board the same.

[0003] like Figure 1 As shown, the conventional etching solution suction knife 90 is equipped with a bracket 91 at both ends, and a positioning seat 92 is provided on the etching table of the etching equipment. The bracket 91 is used to lock the etching solution suction knife 90 onto the positioning seat 92. However, if such a locking design encounters an abnormal state during the etching process, causing a deviation in the horizontality of the etching solution suction knife 90, the etching solution suction knife 90 cannot restore its horizontality on its own, resulting in inconsistent etching rates on the surface of the PCB board and unstable etching quality. Utility Model Content

[0004] The purpose of this invention is to provide a floating etching solution suction knife that can maintain its horizontality.

[0005] Another objective of this invention is to facilitate the adjustment of the position of the etching solution suction knife.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0007] It includes: a suction knife; a pair of floating components disposed at both ends of the suction knife, the floating components having a slider and a slider locking fastener, the slider having a pair of longitudinal guide grooves formed on both sides; and a pair of bases disposed on the etching table of the etching equipment, the bases having a pair of longitudinal guide posts, the pair of longitudinal guide posts forming a slider floating space, the slider being accommodated in the slider floating space.

[0008] Furthermore, the suction knife has a U-shaped positioning part at both ends, and the slider locking fastener secures the slider to the U-shaped positioning part. A slider positioning seat is also provided between the U-shaped positioning part and the slider, and the slider locking fastener secures the slider and the slider positioning seat to the U-shaped positioning part. The contact surfaces of the slider and the slider positioning seat are formed with mutually mating concave and convex structures. The base is formed with multiple pairs of longitudinal guide posts, thereby forming multiple slider floating spaces. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0032] The following is a reference to the appendix. Figure 2 To be continued Figure 5 The present invention comprises: a suction knife 10; a pair of floating components 20 disposed at both ends of the suction knife 10, each floating component 20 having a slider 21 and a slider locking fastener 22, the slider 21 having a pair of longitudinal guide grooves 211 formed on both sides; and a pair of bases 30 disposed on the etching table of an etching device (a predetermined mounting location not shown in the figure), the bases 30 having at least a pair of longitudinal guide posts 31 formed in conjunction with the pair of longitudinal guide grooves 211, the pair of longitudinal guide posts 31 forming a slider floating space 32, the slider 21 being accommodated in the slider floating space 32 by means of the pair of longitudinal guide grooves 211, the pair of longitudinal guide grooves 211 being guided by the pair of longitudinal guide grooves 211, allowing the slider 21 to float in the slider floating space 32.

[0033] Next, the suction knife 10 has a U-shaped positioning part 11 at both ends, and the slider locking fastener 22 locks the slider 21 to the U-shaped positioning part 11; wherein, a slider positioning seat 23 can also be provided between the U-shaped positioning part 11 and the slider 21. The slider 21 is made of UPE material, and the slider positioning seat 23 is made of PVC material. The contact surfaces of the slider 21 and the slider positioning seat 23 are formed with mutually cooperating concave structure 212 and convex structure 231. The slider locking fastener 22 locks the slider 21 and the slider positioning seat 23 to the U-shaped positioning part 11.

[0034] Based on this configuration, the present invention places the pair of bases 30 on the etching table of the etching equipment, and the pair of sliders 21 located at both ends of the suction knife 10 can float up and down in the slider floating space 32 of the base 30. Even if an abnormal state is encountered during the etching process, causing a temporary deviation in the level of the suction knife 10, the pair of sliders 21 can return to the normal position and restore the level of the suction knife 10 after the abnormal state is resolved, thus having the effect of allowing the etching solution suction knife to maintain its level.

[0035] Furthermore, the present invention forms multiple pairs of longitudinal guide posts 31 on the base 30, thereby forming multiple slider floating spaces 32, so that the pair of sliders 21 can be accommodated in different locations as needed.
