[0029] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0030] Please refer to Figure 1-12 , an automatic soldering equipment, including an equipment body 1, a partition 4 is provided in the equipment body 1, the partition 4 divides the equipment body 1 into an upper box body 2 and a lower box body 3, a plurality of universal wheels 5 are provided at the bottom of the lower box body 3, wherein the universal wheels can be locked and the whole can be moved through the universal wheels, a circulation line 8 is provided in the upper box body 2, a plurality of clamping tables 82 are evenly provided on the circulation line 8, a concave cavity 10 for storing electronic components is provided on the surface of the clamping table 82, and the clamping table 82 moves accordingly when the circulation line 8 is running, a plurality of brackets 71 are provided on one side of the circulation line 8, the bottom of the bracket 71 is fixed on the partition 4, and a plurality of the brackets 71 are respectively provided with manipulators 7 for automatic welding, a visual inspection mechanism 11 for detecting solder joints is provided at one end of the circulation line 8, and an automatic sorting mechanism is provided on the side of the circulation line 8 away from the manipulator 7.

[0031] During use, the electronic components to be soldered are automatically loaded by a manipulator or an automatic fixture and placed in a concave cavity 10 on the surface of the clamping table 82. During operation, the circulating line 8 rotates and drives the clamping table 82 to move, thereby sending the electronic components to be soldered to the bottom of the manipulator 7, and the manipulator 7 operates to solder them; after the soldering work is completed, the circulating line 8 rotates and operates again, so that the soldered electronic components are moved to the bottom of the visual inspection mechanism 11, and the visual inspection mechanism 11 can detect defective products such as cold soldering and leaking soldering. After the visual inspection mechanism 11 works, the circulating line 8 rotates and operates again to the automatic line separation module, and the automatic sorting mechanism processes the visual inspection data to sort good / bad products; the entire equipment integrates loading, conveying, soldering, visual inspection, sorting, and unloading, which meets the soldering needs of electronic components, improves welding quality and ensures the yield rate.

[0032] There are three robots, and robots at different welding positions are equipped with different soldering iron tips and different welding parameters. All soldering points of the workpiece can be welded in one cycle, with a high degree of overall automation. In addition, the robot is also equipped with JBC welding module and temperature control, which has the advantages of fast heating, stable welding temperature and good welding effect.

[0033] In this embodiment, electronic components to be soldered are provided above the clamping table 82, and a primary positioning plate 821 is provided above the electronic components. The provision of the primary positioning plate 821 can not only shield other parts, but also make soldering more accurate and improve the soldering accuracy. The clamping table 82 is fixed on the surface of the mobile base 81, and one side of the mobile base 81 is fixed on the circulation line 8. When the circulation line 8 is running, the clamping table 82 is driven to move by the mobile base 81; when in use, the material is first loaded, and then the solder is transported, and then the solder is visually inspected. After the soldering, the good / bad products are screened after the visual inspection. After screening, the workpieces are sorted. After sorting, the cavity 10 is empty and can be loaded again, and the cycle is repeated.

[0034] In order to ensure the stable operation of the clamping table 82, two groups of positioning wheels 812 are further provided under the mobile base 81, each group of positioning wheels 812 has two, and the four positioning wheels are arranged opposite to each other in pairs. The circumference of the positioning wheel 812 is provided with an annular limiting groove, and the surface of the circulation line 8 is provided with a protrusion that cooperates with the annular limiting groove. The two groups of positioning wheels 812 are clamped on both sides of the circulation line 8 through the annular limiting groove; Fig. 9 As shown, each mobile base 81 is limited by four positioning wheels 812 below and the circulation line 8 to prevent the mobile base from vibrating or deviating during the transportation process, so as to ensure the transmission accuracy and improve the solder quality.

[0035] Furthermore, in order to improve the transmission accuracy, a secondary positioning device is also provided around the circulation line 8, and the secondary positioning device includes a positioning rod 831 that can rotate and swing, and the end of the positioning rod 831 is provided with a positioning terminal 832, and the outer side of the movable base 81 is provided with a slot 811 that cooperates with the positioning terminal 832. When the circulation line 8 moves, the positioning rod 831 swings outward to make the positioning terminal 832 disengage from the slot 811, and when the circulation line 8 is stationary, the positioning rod 831 swings in the opposite direction to make the positioning terminal 832 engage in the slot 811.

[0036] After the positioning rod 831 swings outward, the positioning end 832 disengages from the slot 811. At this time, the moving base 81 is unconstrained, and the moving base 81 moves and is transported when the circulation line 8 rotates; when the circulation line 8 is stationary, the positioning rod 831 swings inward and the positioning end 832 is engaged in the slot 811. At this time, the outer side of the moving base 81 is limited by the positioning rod 831 (positioning end 832); that is to say, when the electronic component is switching its working position, the positioning end 832 and the slot 811 do not cooperate, and during the working process, the positioning end 832 and the slot 811 cooperate, and the circulation line 8 performs secondary positioning in the time interval of each stop.

[0037] For ease of understanding, an example is given: during the loading process, the positioning terminal 832 cooperates with the slot 811. After the loading is completed, the positioning terminal 832 is separated from the slot 811 and the circulating line 8 rotates to feed the soldering. During the soldering process (time gap), the positioning terminal 832 cooperates with the slot 811 again; after the soldering is completed, the positioning terminal 832 is separated from the slot 811 and the circulating line 8 rotates to feed the soldering for visual inspection. During the visual inspection, the positioning terminal 832 cooperates with the slot 811 again; this cycle continues, that is, each part will perform secondary positioning on the mobile base 81 when working, which greatly improves the soldering accuracy and avoids angle or position deviation.

[0038] The secondary positioning device also includes an optical axis 83 and a fixed rod 833. Both ends of the optical axis 83 are fixed to the outer wall of the circulation line 8 through an L-shaped fixed seat 834. A bearing that cooperates with the optical axis is provided in the L-shaped fixed seat 834. The optical axis 83 passes through the positioning rod 831 and is fixed. The fixed rod 833 is provided on one side of the positioning rod 831. The optical axis 83 passes through one end of the fixed rod 833 and is fixed. A motor 84 and a plurality of cylinders 85 are provided at the bottom of the circulation line 8. The motor 84 drives the circulation line 8 to rotate. The output end 851 of the cylinder 85 is hinged to the other end of the fixed rod 833. When the output end 851 is extended or retracted, it drives the fixed rod 833 and the positioning rod 831 to swing.

[0039] That is to say, the secondary positioning is driven by the cylinder 85; when the output end 851 of the cylinder 85 contracts, the fixing rod 833 will be pulled. Since the fixing rod 833 and the positioning rod 831 are both fixed to the optical axis, the pulled fixing rod 833 can make the positioning rod 831 swing outward and the optical axis rotate a certain angle. After the positioning rod 831 swings outward, the positioning end 832 disengages from the slot 811, and the circulation line 8 can rotate and transport at this time; when the output end 851 of the cylinder 85 extends, the fixing rod 833 will be pushed. Similarly, the fixed rod 833 after being pushed can make the positioning rod 831 and the optical axis 83 rotate in the opposite direction. After the reverse rotation, the positioning end 832 is inserted into the slot 811 to realize the secondary positioning, and this cycle is repeated.

[0040] In this embodiment, the secondary positioning device corresponds to the movable base 81 one by one, that is, each movable base 81 can be secondary positioned when it moves to the next station.

[0041] Based on the above embodiments, the cylinder that controls the secondary positioning, the motor that controls the conveyor line, the robotic arm, etc. are all precisely controlled by the PLC control system.

[0042] In this embodiment, the visual inspection mechanism 11 includes a laterally arranged U-shaped frame 111, a horizontal extension rod 112 is fixed to the top of the U-shaped frame 111, a visual inspection module 113 is provided at the end of the extension rod 112, a support plate 114 is provided inside the U-shaped frame 111, a circular hole 115 is provided on the surface of the support plate 114, the visual inspection module 113 is arranged directly above the circular hole 115, wherein the inner diameter of the circular hole 115 is larger than the contour of the clamping table 82, so that the visual inspection module 113 can fully capture the workpiece, and a T-shaped fixing plate 116 is provided at the bottom of the U-shaped frame 111, and the U-shaped frame 111 is fixedly connected to the partition 4 via the T-shaped fixing plate 116.

[0043] In addition, the circumferential inner wall of the circular hole 115 is also provided with a light strip to provide a light source, and the light source emitted by the light strip is preferably red light; when the circulation line 8 transports the soldered workpiece to the bottom of the circular hole 115, it stops, and after stopping, it performs a secondary positioning, while the light strip flashes red light and the visual inspection module 113 photographs the solder surface of the electronic components; defective products are screened out by data comparison; after photographing, the secondary positioning is completed and subsequent sorting is carried out.

[0044] In this embodiment, the visual inspection module 113 is a Hikvision industrial camera, which takes pictures to identify data information such as welding shape and size, and transmits the identified information to the processing system. The system analyzes and processes the data information and sends sorting instructions; the automatic sorting mechanism sorts it after receiving the instructions and places good and defective products in different conveying positions.

[0045] Some electronic components that are soldered may have defective products such as leaking solder joints and cold solder joints. The defective products are selected through an automatic sorting mechanism, which includes a reference rod 9 and a drag chain 96 on one side of the reference rod 9. One end of the reference rod 9 is provided with a connecting plate 92 that can translate along itself, and one end of the drag chain 96 is fixedly connected to the connecting plate 92. The retraction of the drag chain 96 can drive the connecting plate 92 to translate along the reference rod 9. A servo motor 91 is provided on the connecting plate 92, and the servo motor 91 is connected to the clamping cylinder 93 below through a screw structure; the screw structure is an ordinary screw lifting structure, which will not be described in detail here; after the servo motor 91 is running, the screw structure drives the clamping cylinder 93 to rise and fall, and a clamp for clamping electronic components is provided below the clamping cylinder 93, and the clamp clamps the electronic components and places them on the conveyor belt; during use, the electronic components are visually inspected and defective products are screened out, and the defective product data information is transmitted to the automatic sorting mechanism, so as to distinguish between good and defective products.

[0046] In this embodiment, movable plates 94 are provided on both sides of the clamping cylinder 93 , and L-shaped clamping plates 95 are provided below the movable plates 94 . When the clamping cylinder 93 is in operation, the electronic components are clamped by the two clamping plates 95 .

[0047] When automatically sorting and unloading, the drag chain 96 pulls the connecting plate 92 to move the whole body into the equipment body 1. At this time, the servo motor 91 is running and the clamping cylinder 93 moves. The clamping cylinder 93 controls the two clamping plates 95 to open the two clamping plates 95. After opening, the electronic components are placed between the two clamping plates 95. The clamping cylinder 93 clamps the workpiece after running; after clamping, the drag chain 96 runs again to push the connecting plate 92, so that the whole body moves outward along the reference rod 9, and moves to the appropriate position. After moving to the appropriate position, the whole body moves downward, and at the same time, the clamping cylinder 93 runs to loosen the clamping plate, so that the electronic components are placed on the conveyor belt. Automatic sorting is achieved in this reciprocating manner.

[0048] In this embodiment, the conveyor belt includes conveyor belt 1 61 and conveyor belt 2 62, and both conveyor belt 1 61 and conveyor belt 2 62 are arranged on the outside of the equipment body 1 and are located below the outer end of the reference rod 9, wherein conveyor belt 1 61 is used to place good solder products, and conveyor belt 2 62 is used to place defective solder products so as to distinguish them from good / defective products.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
