Description

Technical Field

[0001] This utility model belongs to the technical field of wave soldering equipment, specifically relating to a rapid correction device for solder pot spacing in selective wave soldering. Background Technology

[0002] Selective wave soldering equipment is widely used in the electronics manufacturing industry for selective soldering of PCBs. It typically features two movable solder pots to accommodate solder joints or circuit boards of different sizes. During production, frequent product changeovers require repeated adjustments to the spacing between the two solder pots. Current adjustment methods rely primarily on operators manually measuring and positioning using standard circuit boards and calipers. This process is not only cumbersome, involving multiple steps such as cleaning and inspection, manual coarse adjustment, precision measurement, repeated verification, and tightening, resulting in each changeover calibration taking 2 to 3 hours; but its accuracy also heavily depends on the operator's experience and responsibility, posing a risk of human error that directly impacts soldering quality and production efficiency, while also leading to low equipment utilization and high labor costs. Therefore, the industry urgently needs a solution that enables rapid, accurate, and one-click solder pot spacing calibration. Utility Model Content

[0003] This invention aims to provide a rapid correction device for the solder pot spacing in selective wave soldering, which solves the technical problems of existing selective wave soldering solder pot spacing adjustment methods being cumbersome to operate, time-consuming, and difficult to guarantee accuracy.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rapid correction device for solder pot spacing in selective wave soldering includes a correction block. One end of the correction block is provided with a reference positioning part for positioning and cooperating with a reference solder pot, and the other end is provided with a movable positioning part for positioning and cooperating with a movable solder pot. The distance between the reference positioning part and the movable positioning part is equal to the target working distance between the reference solder pot and the movable solder pot.

[0005] Furthermore, the reference positioning part and the movable positioning part are positioning holes, which are used to cooperate with the positioning posts fixedly installed on the tin pot.

[0006] Furthermore, the correction block is made of a stress-relief metal material.

[0007] Furthermore, the calibration block has two circular holes for mounting handles.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a calibration block with precise spacing, this utility model transforms the complex process of relying on manual measurement and repeated debugging into a simple "one set, one lock" operation, which greatly improves calibration efficiency and shortens the changeover time from several hours to less than ten minutes. At the same time, the device replaces manual reading and measurement with mechanical positioning, completely eliminating human error and ensuring the consistency and reliability of calibration accuracy, thereby significantly improving production quality, equipment utilization and production flexibility.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] The present invention will be further described in detail below with reference to the embodiments.

[0012] like Figure 1-3 As shown, the core of the quick correction device for solder pot spacing in selective wave soldering provided by this utility model is a specially designed and manufactured correction block 1.

[0013] The correction block 1 is an integrally formed rectangular block structure made of 45 steel or aluminum alloy that has undergone stress-relief annealing to ensure stable mechanical properties and prevent deformation under long-term use and temperature changes, thus maintaining high precision.

[0014] One end of the correction block 1 is machined with a first circular hole as a reference positioning part 11; the other end is machined with a second circular hole as a movable positioning part 12. The center distance between the reference positioning part 11 and the movable positioning part 12 is precision machined, and its size is exactly equal to the target working distance required between the reference solder pot and the movable solder pot during the operation of the selective wave soldering equipment.

[0015] Corresponding to the first and second circular holes on the calibration block 1, positioning posts are fixedly installed at the corresponding positions of the reference tin pot and the movable tin pot. The diameter of the positioning post is in close clearance fit with the hole diameter of the reference positioning part 11 and the movable positioning part 12 on the calibration block 1, for example, H7 / g6, so as to ensure that it can be easily inserted and accurately positioned.

[0016] In addition, to facilitate the operator's handling and placement, two handle mounting holes 13 are provided on the upper surface of the calibration block 1, and a U-shaped handle (not shown in the figure) can be installed by bolting or screwing in.

[0017] The working process of this utility model is as follows: The operator holds the handle and picks up the calibration block 1. It is confirmed that the surfaces of the positioning posts of the reference solder pot and the movable solder pot are clean and free of solder residue or oil. The reference positioning part 11 (i.e., the first circular hole) at one end of the calibration block 1 is aligned and fitted onto the positioning post of the fixed reference solder pot. At this point, the calibration block 1 is initially positioned with the reference solder pot as the reference.

[0018] In the control system, loosen the locking mechanism of the movable solder pot. Manually or drive the movable solder pot to move it, aligning its positioning pin with and fitting it into the movable positioning part 12 (i.e., the second circular hole) at the other end of the correction block 1. When the positioning pin of the movable solder pot is fully inserted into the movable positioning part 12, it indicates that the distance between the two solder pots has been precisely corrected to the target dimension L. At this point, immediately tighten the fixing mechanism of the movable solder pot. Lift the correction block 1 upwards, separating its two positioning holes from the positioning pins on the solder pot, thus completing the correction process. The entire process can be completed within 10 minutes, making it extremely efficient.

[0019] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
