[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] The core of the present application is to provide a soldering machine track system for avoiding silver glue overflow from a frame, which can effectively solve the problem of silver glue overflow from the frame due to the fluidity of the silver glue after the dispensing and soldering operations are sequentially completed on the soldering machine track and before entering the oven for baking. Another core of the present application is to provide a soldering machine comprising the above-mentioned soldering machine track system for avoiding silver glue overflow from a frame.

[0037] Please refer to Figure 3 and Figure 4 , wherein, Figure 3 is a structure diagram of the soldering machine track system for avoiding silver glue overflow from a frame provided by the present application; Figure 4 is a structure diagram of silver glue not overflowing from a frame after using the system.

[0038] The present embodiment provides a soldering machine track system for avoiding silver glue overflow from a frame, comprising:

[0039] a dispensing head 1;

[0040] a soldering piece head 2;

[0041] a first conveying track 3 for driving the frame 6 to enter from a feeding port and sequentially move to below the dispensing head 1 and below the soldering piece head 2;

[0042] a second conveying track 4 for driving the frame 6 to move from below the soldering piece head 2 to a discharging port;

[0043] a heating device 5 corresponding to the second conveying track 4, for heating the frame 6 moving on the second conveying track 4;

[0044] The control device, the dispensing head 1, the soldering head 2, the first conveying track 3, the second conveying track 4 and the heating device 5 are connected with the control device.

[0045] It should be noted that the soldering machine is also called "mounting machine" or "surface mounting system". In the production line, the soldering machine is arranged after the dispensing machine or the screen printing machine, and is a device for accurately placing the surface mounting components on the PCB pad through the moving mounting head. That is, the soldering machine mainly includes two actions of dispensing and soldering, the frame 6 (i.e. the PCB pad) runs on the track, and is dispensed at the dispensing position first, then is conveyed to the soldering position for soldering, and finally is discharged to wait for the oven baking.

[0046] In order to avoid the problem that the silver glue 7 of individual products overflows the frame 6 due to the too long residence time of the products in the residence stage before the soldering and baking, the silver glue 7 pre-solidification function (for example, the pre-solidification of the products through the area heating before the soldering and baking) can be added in the residence stage of the products before the soldering and baking (i.e. the stage of conveying the frame 6 by the second conveying track 4), so as to increase the offset tolerance rate of the dispensing and soldering position of the soldering station.

[0047] It should be further noted that the device further includes the wafer 8 connected with the control device. The wafer 8 is a power management triode, which is a kind of semiconductor device for controlling current, and functions to amplify the weak signal into the electric signal with large amplitude value, and is also used as a non-contact switch. In the actual application process, the shape, structure, size, material, type and position of the dispensing head 1, the soldering head 2, the first conveying track 3, the second conveying track 4, the heating device 5 and the control device can be determined according to the actual situation and actual demand.

[0048] When the soldering machine track system for avoiding the silver glue overflow frame provided by the utility model is used, first, the control device controls the first conveying track 3 to run, so as to drive the frame 6 with the chip to enter from the feeding port and move to the lower side of the dispensing head 1. Then, the control device controls the dispensing head 1 to run, so as to perform the dispensing operation on the frame 6. Then, the control device controls the first conveying track 3 to continue running, so that the frame 6 moves to the lower side of the soldering head 2. Thereafter, the control device controls the soldering head 2 to run, so as to press the chip and other surface mounting components on the silver glue 7 by the soldering head 2, so that the chip and other surface mounting components are welded on the frame 6. At the same time, the control device can control the heating device 5 to run, so as to heat the second conveying track 4, so that the heating operation is realized in the area of the second conveying track 4. Finally, the control device controls the second conveying track 4 to run, so that the frame 6 is conveyed from the end of the first conveying track 3 to the second conveying track 4. The silver glue 7 on the frame 6 is quickly pre-solidified and shaped under the high temperature condition, and will not flow everywhere, that is, the second conveying track 4 which can be heated helps the silver glue 7 to be quickly pre-solidified, effectively preventing the silver glue 7 from overflowing the frame 6 and causing the product to be scrapped, such as Figure 4As shown.

[0049] In summary, the soldering piece machine track system for avoiding silver adhesive overflow from the frame can effectively solve the problem of silver adhesive 7 overflow from the frame 6 due to the fluidity of the silver adhesive 7 after the product completes the dispensing and soldering piece operations on the soldering piece machine track and before entering the oven for baking.

[0050] In an embodiment, the heating device 5 includes a heating couple arranged in the second conveying track 4. That is, the second conveying track 4 with the heating couple can achieve the purpose of pre-curing the product, so that the product is quickly and timely pre-cured on the second conveying track 4 to prevent the silver adhesive 7 from overflowing from the frame 6. One or more heating couples can be arranged in the second conveying track 4, and the position, heating power, etc. of the heating couple can be determined according to actual conditions and actual needs.

[0051] In an embodiment, the heating device 5 includes an electric oven, the second conveying track 4 is arranged in the electric oven, and the electric oven is provided with an inlet and an outlet along the conveying direction of the second conveying track 4. That is, the electric oven can be used to heat the second conveying track 4 after the product is soldered and before the product formally enters the oven for baking in the next stage, so that the product moving on the second conveying track 4 is heated and warmed, and the product is quickly and timely pre-cured on the second conveying track 4 to prevent the silver adhesive 7 from overflowing from the frame 6 and damaging the product.

[0052] In an embodiment, the heating device 5 includes an electric heating fan, and the side of the second conveying track 4 is provided with the electric heating fan. That is, the electric heating fan can be arranged on one side or both sides of the second conveying track 4 to heat the product, so that the product is quickly pre-cured on the second conveying track 4 to prevent the silver adhesive 7 from overflowing from the frame 6 and damaging the product.

[0053] In an embodiment, the heating device 5 includes an infrared tunnel furnace, and the second conveying track 4 is arranged in the infrared tunnel furnace, and the infrared tunnel furnace is provided with an inlet and an outlet along the conveying direction of the second conveying track 4 to heat the second conveying track 4 by using the infrared rays of the infrared tunnel furnace.

[0054] In an embodiment, the heating device 5 includes a focused laser beam arranged on one side or both sides of the second conveying track 4 to heat the second conveying track 4 by using the laser of the focused laser beam.

[0055] In an embodiment, the heating device 5 includes a microwave curing furnace, and the second conveying track 4 is arranged in the microwave curing furnace, and the microwave curing furnace is provided with an inlet and an outlet along the conveying direction of the second conveying track 4 to heat the second conveying track 4 by using the microwaves of the microwave curing furnace.

[0056] In an embodiment, the heating device 5 comprises a pulse thermal compression bonding machine arranged on one side of the second conveying track 4, and a thermal compression head of the pulse thermal compression bonding machine is used to heat the second conveying track 4 to utilize pulse heating of the pulse thermal compression bonding machine. That is, the pulse thermal compression bonding machine utilizes low voltage and large current to heat the thermal compression head with high impedance by loading a certain pulse voltage on the thermal compression head, so as to heat the object in contact with the thermal compression head.

[0057] In an embodiment, the first conveying track 3 and the second conveying track 4 are in a split structure or an integrated structure, and the first conveying track 3 and the second conveying track 4 are in the same height.

[0058] It should be noted that the first conveying track 3 and the second conveying track 4 can be arranged in a split structure, so that the first conveying track 3 for dispensing and welding piece area is separated from the second conveying track 4 for heating and pre-curing area, thereby avoiding the heating device 5 for heating the second conveying track 4 from directly contacting the first conveying track 3 and affecting the dispensing and welding piece operation on the first conveying track 3. In addition, the first conveying track 3 and the second conveying track 4 are in the same height, and the distance between the first conveying track 3 and the second conveying track 4 is small, so that the product can be smoothly transferred from the first conveying track 3 to the second conveying track 4.

[0059] It should be further noted that the first conveying track 3 and the second conveying track 4 can also be arranged in an integrated structure, but a heat insulation member needs to be arranged at the boundary between the first conveying track 3 and the second conveying track 4, so as to avoid the heat of the heating device 5 from being transferred to the first conveying track 3 and affecting the normal operation of the product on the first conveying track 3. In actual application, the structure and size of the first conveying track 3 and the second conveying track 4 can be determined according to actual conditions and actual requirements.

[0060] In addition to the above-mentioned welding machine track system for avoiding silver glue overflow frame, the welding machine track system for avoiding silver glue overflow frame disclosed in the above-mentioned embodiment is also provided, and the structure of other parts of the welding machine can refer to the prior art, which will not be described herein.
