Description

Technical Field

[0001] The utility model belongs to the technical field of automatic soldering machines, and particularly relates to a positioning fixture for an automatic soldering machine. Background Art

[0002] Soldering is an important part of electronic manufacturing. Ensuring soldering accuracy and efficiency is crucial to improving product quality and reducing costs. For example, soldering of motherboards;

[0003] Existing automatic soldering machines can perform soldering operations on motherboard products, but they cannot limit the position of the products, and they use one-to-one soldering. If the automatic soldering machine is not designed with a special limit device, it may not be possible to ensure precise alignment when the product is placed. This will cause the position of the solder point and the pad on the motherboard to deviate, affecting the quality of soldering. The lack of a limit device means that the position of the product may be different each time it is placed, which will reduce the consistency of soldering, and the quality and shape of each solder point may be different. Since the product cannot be accurately aligned, the operator may need to adjust the product position frequently, which increases the number of manual interventions, which is not only inefficient but also may introduce human errors.

[0004] If an automatic soldering machine is limited to one-on-one soldering, processing only one product at a time, this significantly reduces production efficiency. In mass production, this limitation results in longer production cycles, making it impossible to meet the demands of large-scale production. One-on-one soldering means the automatic soldering machine has idle time between each soldering operation, which wastes machine resources and increases unit production costs. Frequent single operations also affect operational continuity and stability, increasing the risk of errors during production.

[0005] In order to overcome these problems, we propose a positioning fixture for an automatic soldering machine with a limiting device and one-to-many welding capability to solve the above problems. Utility Model Content

[0006] The present invention aims to solve the technical problem that in the prior art, there is no limiting device, the product placement and the automatic soldering machine cannot be aligned, the soldering cannot reach the accurate point, and only one product can be soldered at a time.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A positioning fixture for an automatic soldering machine, comprising:

[0009] The jig platform base is connected to the automatic soldering machine platform and fixed on the automatic soldering machine, and the jig platform base is provided with three metal circular columns A arranged in a triangular shape and a balance bar;

[0010] The jig lower cover is connected to the jig platform base. The jig lower cover is provided with three circular metal holes for seamless insertion of three metal circular columns A, four magnets A, three circular metal columns B and six grooves A for inserting products.

[0011] The upper cover of the jig is connected to the lower cover of the jig. The upper cover of the jig is provided with three positioning holes for seamlessly fitting and positioning with the circular metal column B, four magnets B for magnetic attraction with the magnet A, and a groove B for placing the product.

[0012] Preferably, the fixture platform base is an I-shaped structure.

[0013] The I-shaped structure increases the bending rigidity and stability of the base, making the entire fixture more stable when operated on the automatic soldering machine. This structural design facilitates connection with the automatic soldering machine platform, ensuring that the fixture can be accurately installed on the machine.

[0014] Preferably, the fixture platform base is provided with four screw holes for locking and fixing with the automatic soldering machine platform.

[0015] The screw holes are used to lock the fixture platform base to the automatic soldering machine platform, providing stable support and fixation to prevent shifting during the soldering process. The screw hole design facilitates the installation and adjustment of the fixture position to ensure welding accuracy.

[0016] Preferably, the balance bar is located at the front end of the four screw holes and the three metal circular columns A.

[0017] The balance bar, located in front of the four screw holes and three metal circular columns A, helps maintain the levelness of the fixture platform base and ensures the balance of the product when placed. This can reduce deviation caused by platform imbalance during the welding process and improve welding quality.

[0018] Preferably, the lower cover of the jig and the upper cover of the jig are fitted and docked together by magnet A and magnet B.

[0019] The magnetic attraction between magnets A and B allows the lower and upper covers of the fixture to be quickly joined together, improving work efficiency. The magnetic attraction also ensures precise alignment of the upper and lower covers, reducing welding errors.

[0020] Preferably, the lower cover of the jig is provided with four small circular metal columns that are connected to and sunk into the positioning holes of the product for positioning.

[0021] These small circular metal columns, combined with the positioning holes, can precisely secure the product to the jig, ensuring the accuracy of the welding position. The design of the small circular metal columns can also prevent the product from sliding during the welding process, increasing the stability of the operation.

[0022] Compared with the prior art, the technical effects and advantages of the utility model are:

[0023] This automatic soldering machine uses a positioning jig. Three circular metal columns A on the jig platform base mate with three circular metal holes on the jig's lower cover, ensuring the cover fits precisely on the jig platform base. A balance bar helps maintain the levelness of the entire jig platform, ensuring the motherboard is balanced during placement and preventing inaccurate positioning caused by platform tilt.

[0024] The jig's lower cover features six grooves A, which can be used to position and position multiple motherboards, not just one. This allows for simultaneous soldering of multiple products, significantly improving production efficiency. The ability to place multiple motherboards in the jig at once and complete soldering of multiple products in the automatic soldering machine significantly improves production efficiency.

[0025] Four magnets A on the jig's lower cover magnetically attach to magnets B on its upper cover, ensuring a tight fit between the upper and lower layers and preventing product displacement. Positioning holes on the jig's lower cover mate with small, circular metal posts to ensure accurate alignment of the motherboard when placed in the jig.

[0026] Through these multiple positioning and fixing methods, the overall structure is very stable, ensuring that the motherboard's position does not shift during the soldering process, thereby improving soldering accuracy. In short, this automatic soldering machine positioning fixture, through its precise positioning and fixing design, solves the problems of existing automatic soldering machines' inability to limit product positioning, perform one-to-one soldering, and align product placement, greatly improving soldering accuracy and production efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following is combined with Figure 1-4 To further explain this application,

[0034] The present application discloses a positioning jig for an automatic soldering machine, comprising a jig platform base 1, a jig lower cover 2, and a jig upper cover 3. The jig platform base 1 is coupled to the automatic soldering machine platform and fixed to the automatic soldering machine, the jig lower cover 2 is coupled to the jig platform base 1, and the jig upper cover 3 is coupled above the jig lower cover 2.

[0035] The fixture platform base 1 is an I-shaped structure. The fixture platform bottom is provided with four screw holes 11 for locking and fixing with the automatic soldering machine platform, three metal circular columns A12 arranged in a triangle, and a balance bar 13. The balance bar 13 is located at the front end of the four screw holes 11 and the three metal circular columns A12.

[0036] The lower cover 2 of the fixture is provided with three circular metal holes 21 for seamless insertion of the three metal circular pillars A12, four magnets A22, three circular metal pillars B24 and six grooves A25 for inserting the product;

[0037] The jig's upper cover 3 is equipped with three positioning holes 31 for seamless insertion and positioning with circular metal pillars B24, four magnets B32 for magnetic attraction with magnets A22, and a groove B33 for inserting the product. The jig's lower cover 2 is equipped with four circular metal pillars 23 that connect to and fit into the product's positioning holes 31 for positioning. Magnets A22 and B32 magnetically attract each other, securing the jig's lower and upper covers 2 and 3 together.

[0038] The positioning jig for the automatic soldering machine includes a jig platform base 1, a jig lower cover 2 and a jig upper cover 3. The circular metal hole 21 is plugged into the metal circular column A12, and the jig lower cover 2 is joined to the top of the jig platform base 1. The motherboard to be soldered is placed on the jig platform base 1 and the jig lower cover 2, and positioned according to the six grooves A25. The jig upper cover 3 is installed, and the magnet A22 and the magnet B32 are used to magnetically attract the jig lower cover 2 and the jig upper cover 3 to fit together and fix the motherboard in the appropriate position. The battery is placed in the designated positioning groove, and the groove ensures the accurate position of the battery. After completing the above steps, the jig with the motherboard and battery is placed in the automatic soldering machine for soldering.

[0039] This automatic soldering machine positioning jig ensures the motherboard's positional accuracy during the soldering process through precise docking of the jig platform base 1 with the automatic soldering machine platform, and magnetic positioning between the jig lower cover 2 and jig upper cover 3. This design reduces the need for manual adjustments and reduces human error.

[0040] The overall structural design of the fixture takes stability into consideration. The close combination of the upper and lower covers and the adsorption effect of the magnets ensure the stability of the product during the welding process, thereby ensuring the accuracy and consistency of the solder joints.

[0041] This design allows six motherboards to be placed simultaneously, allowing multiple products to be soldered in a single operation, significantly improving production efficiency. The ability to perform soldering operations continuously reduces machine changeover and adjustment time, further increasing production capacity.

[0042] The positioning holes 31 and grooves in the jig ensure precise placement of each product, ensuring that each solder joint accurately aligns with the intended soldering location. This precise positioning reduces soldering errors and improves product quality. Furthermore, continuous soldering reduces downtime and avoids quality issues that can arise from frequent adjustments. This increased level of automation means less manual work, reducing the number of operators and saving labor costs.

[0043] The positioning fixture's one-to-six design, combined with the use of simulated dimensions, allows for the simultaneous processing of six products in a single fixture, significantly improving production efficiency. The grooves in the fixture utilize the simulated dimensions of the products, allowing the fixture to be customized to their actual dimensions. This allows for more precise placement of the products within the fixture, ensuring accurate and consistent welding.

[0044] In summary, this positioning fixture for automatic soldering machines not only improves welding quality and efficiency but also reduces production costs by optimizing design and improving automation level. It is an effective solution to improve production efficiency and quality in the electronics manufacturing industry.
