Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the DIP line in the present embodiment includes a card work table 1, a soldering apparatus 2, and a carrier reflow system, and the soldering apparatus 2 is disposed at the rear end of the card work table 1 along a feeding direction (the feeding direction in the present embodiment refers to a direction in which a carrier carrying a PCB is transferred from the card work table 1 to the soldering apparatus 2). The carrier reflow system includes a lifting mechanism 3, a first transmission mechanism, a second transmission mechanism 5, a third transmission mechanism and a fourth transmission mechanism 7. The lifting mechanism 3 is correspondingly arranged at the output end of the welding equipment 2, the first transmission mechanism penetrates through the bottom of the welding equipment 2, and the input end of the first transmission mechanism is correspondingly arranged with the output end of the lifting mechanism 3; the input end of the second transmission mechanism 5 is arranged corresponding to the output end of the first transmission mechanism, and the input end of the third transmission mechanism is arranged corresponding to the output end of the second transmission mechanism 5; the input end of the fourth transmission mechanism 7 is arranged corresponding to the output end of the third transmission mechanism, and the output end of the fourth transmission mechanism 7 is arranged corresponding to the input end of the plug-in workbench 1, so that a loop for a reflow carrier is formed. The first conveying mechanism and the third conveying mechanism are used for conveying the carriers along the direction opposite to the feeding direction, and the second conveying mechanism 5 and the fourth conveying mechanism 7 are used for conveying the carriers along the direction perpendicular to the feeding direction.

In particular, the output end of the inserter table 1 may be substantially aligned with the input end of the welding device 2 for a rational layout of the production line, facilitating personnel work.

Specifically, as shown in fig. 3, the lifting mechanism 3 includes a first cart 31 for transporting the carrier, a first guide rail 32, and a first driving unit (not shown). The first guide rail 32 may be vertically disposed at the output end of the welding apparatus 2, and the first carriage 31 includes a roller (not shown) which is rotatable in the direction opposite to the feeding direction, and under the rolling of the roller, the carrier may move toward the second conveying mechanism. The first driving unit can drive the first carriage 31 to move up and down along the first guide rail 32. Further, when there is no carrier on the first trolley 31, the first driving unit drives the first trolley 31 to move to the top of the first guide rail 32 for waiting, and when the person places the carrier on the first trolley 31, the first driving unit drives the first trolley 31 to move downward to the bottom of the first guide rail 32, and at this time, the input ends of the first trolley 31 and the second transmission mechanism are located at substantially the same horizontal height, and the carrier is transferred to the second transmission mechanism by the rotation of the roller of the first trolley 31. Preferably, the height from the top of the first guide rail 32 to the ground is approximately 1-1.2 m, so that the operator can place the carrier without bending down, and the operation intensity of the operator can be reduced.

Specifically, as shown in fig. 4, the first conveyance mechanism includes a first conveyor belt 4 and a second drive unit (not shown in the figure) for driving the first conveyor belt 4. Similarly, the third transfer mechanism may also include the second conveyor belt 6 and a third driving unit (not shown in the figure) for driving the second conveyor belt 6 to operate. Preferably, the level of the second conveyor 6 is substantially the same as the level of the inserter table 1, and the second conveyor 6 may be arranged horizontally at the back side of the inserter table 1 (i.e. the side opposite to the side on which the person stands during operation), so that it is also possible to arrange additional persons to stand in front of the second conveyor 6 for inserter operation when there is a need to increase the throughput of the inserter station. By adopting the above scheme, the first transmission mechanism and the third transmission mechanism in the embodiment have simple structures and are easy to implement.

Specifically, as shown in fig. 4, the second transmission mechanism 5 includes a second cart 51, a second rail 52 horizontally disposed, a third rail 53 vertically disposed at an output end of the second rail 52, and a fourth driving unit (not shown). The fourth driving unit can drive the second carriage 51 to move horizontally along the second guide rail 52 and move up and down along the third guide rail 53. Further, in the present embodiment, the input end of the welding device 2 is aligned with the card insertion table 1, and the second conveyor belt 6 is disposed on the back surface of the card insertion table 1, so that the first conveyor belt 4 and the second conveyor belt 6 penetrating the bottom of the welding device 2 are disposed to be substantially offset in both the horizontal direction and the vertical direction. The second transport mechanism 5 in this embodiment may cooperate with a horizontally disposed second rail 52 and a vertically disposed third rail 53 to transport the second cart 51 onto the second conveyor 6.

Specifically, as shown in fig. 5, the fourth transfer mechanism 7 includes a third carriage 71, a horizontally disposed fourth guide rail 72, and a fifth driving unit (not shown). The fifth driving unit can drive the third trolley 71 to move along the fourth guide rail 72, so that the third trolley 71 moves back and forth between the fourth transmission mechanism 7 and the card insertion workbench 1, and the carrier transportation is realized.

Further, the third cart 71 and the fourth rail 72 may be rotatably connected, in other words, the third cart 71 may rotate relative to the fourth rail 72. Specifically, the third cart 71 carrying the carrier may first translate on the fourth rail 72, and when moving to the middle of the fourth rail 72, the third cart 71 may rotate 180 ° to change the direction of the carrier thereon (generally, the carrier is designed to have a certain directionality for fool-proof purpose, and the side of the carrier facing the operator during operation is referred to as the front side), and then the third cart 71 may further drive the carrier to translate along the fourth rail 72 to the input end of the card workstation 1.

By adopting the scheme, when a person puts the carrier into the backflow system from the lifting mechanism 3, the carrier can be turned by 180 degrees along the direction of the incoming material, namely, when the carrier enters the backflow system, the front side of the carrier is back to the plug-in workbench 1 (and is also back to an operator in front of the plug-in workbench 1), namely, the front side of the carrier is right opposite to the operator in front of the second conveyor belt 6; when the carrier moves along the fourth guide rail 72 along with the third trolley 71, the carrier can rotate 180 degrees along with the third trolley 71 and then continue to move to the card insertion workbench 1, so that when the carrier is reflowed to the card insertion workbench 1, the front side of the carrier can be directly opposite to an operator in front of the card insertion workbench 1. Therefore, when the carrier is on the plug-in workbench 1 or the second conveyor belt 6, the front side of the carrier can be directly opposite to the corresponding operator, so that the corresponding operator can directly operate on the carrier conveniently without manually rotating the carrier.

In summary, compared with the prior art, in the DIP production line in the embodiment, the carrier reflow system is arranged between the plug-in station and the soldering station, so that the carrier can reflow to the plug-in station in time after passing through the heating furnace, the utilization rate of the carrier is improved, the carrier input amount between the two work stations can be reduced, the labor expenditure can be reduced, and the production cost can be reduced. In addition, in the carrier reflow system in this embodiment, the lifting mechanism 3 may be disposed below the output end of the welding device 2, the first transmission mechanism may be disposed at the bottom of the welding device 2 in a penetrating manner, and the third transmission mechanism may also be used as a temporary working platform.
