Description

Technical Field

[0001] The utility model relates to the technical field of SMT soft board processing, in particular to a drying device for SMT soft board processing. Background Art

[0002] SMT plays an important role in the field of electronic manufacturing. As electronic products develop towards miniaturization, lightweight and multifunctionality, the application of SMT flexible circuit boards is becoming more and more extensive. In the processing of SMT flexible circuit boards, drying is a key step.

[0003] Traditional drying equipment for SMT flexible circuit board processing usually places the SMT flexible circuit board into a special tray before drying, and transports it to the dryer by a conveyor belt for drying. Common trays generally have small holes at the bottom to facilitate air circulation, thereby drying the front and back sides of the SMT flexible circuit board. During the transportation process, because the bottom of the tray is in contact with the surface of the conveyor belt, air cannot circulate smoothly, which will prevent the bottom of the SMT flexible circuit board from being effectively dried, resulting in uneven drying of the SMT flexible circuit board, requiring secondary drying, which takes too long and affects production efficiency.

[0004] In addition, the stability of the pallet during transportation is also very important. During transportation, the pallet may tilt or collide, which may damage the SMT flexible circuit board, increase the loss during processing, and thus lead to economic losses. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0030] Reference Figure 1 - Figure 3 A drying device for SMT soft board processing includes a conveyor frame 1, and a conveyor 2 is provided on the upper surface of the conveyor frame 1. The conveyor 2 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A dryer 3 is provided on the upper surface of the conveyor frame 1, and a thermal insulation curtain 4 is provided on the lower surface of the dryer 3 to effectively prevent heat from dissipating. A clamping component is provided on the lower surface of the conveyor frame 1, and the clamping component includes an electric telescopic rod 52. The electric telescopic rod 52 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. More description, the lower surface of the electric telescopic rod 52 is fixedly connected with a U-shaped plate 51, and the inner wall of the U-shaped plate 51 is fixedly connected with a sliding rod 53. When sliding, the U-shaped plate 51 can drive the sliding rod 53 to squeeze the inner wall of the slide groove 501. The left surface of the U-shaped plate 51 passes through and is slidably connected with a transmission plate 54. The right surface of the transmission plate 54 is fixedly connected with a splint 55. When the transmission plate 54 slides horizontally, it can drive the splint 55 to move synchronously. The upper surface of the conveyor 2 is fixedly connected with a push plate 56, which can push the tray for placing the SMT soft board. The front surface of the transmission plate 54 is provided with a slide groove 501, and a conveying component is arranged inside the splint 55.

[0031] The conveying assembly includes a spring 61, the lower end of the spring 61 is fixedly connected to a clamping plate 62, the inner wall of the clamping plate 55 is rotatably connected to a wheel shaft 64 for supporting a conveying wheel 63, and the outer wall of the wheel shaft 64 is fixedly connected to the conveying wheel 63. When the SMT soft board tray is pushed, it will drive the conveying wheel 63 to roll.

[0032] Reference Figure 1 、 Figure 2 The electric telescopic rod 52 is set on the lower surface of the conveyor frame 1, and the U-shaped plate 51 slides on the outer wall of the conveyor frame 1. When the electric telescopic rod 52 is started, the U-shaped plate 51 will be driven to slide longitudinally on the outer wall of the conveyor frame 1. The sliding rod 53 is slidably connected to the inner wall of the slide groove 501. The slide groove 501 is set to an inclined shape. When the inner wall of the slide groove 501 is squeezed, it will drive the transmission plate 54 to slide horizontally.

[0033] The transmission plate 54 passes through the right surface of the conveyor frame 1 without causing any obstruction. The splint 55, the sliding rod 53, and the transmission plate 54 are provided in two groups. The two groups of splints 55, the sliding rod 53, and the transmission plate 54 are symmetrically arranged with respect to the center of the conveyor frame 1. When the transmission plate 54 slides, it can drive the splint 55 to move, thereby changing the distance between the splint 55 and the center of the conveyor frame 1.

[0034] Reference Figure 1 、 Figure 3 The other end of the spring 61 is fixedly connected to the inner wall of the upper end of the splint 55, and the card plate 62 is slidably connected to the inner wall of the splint 55. The front surface of the card plate 62 is set as an inclined surface. When the card plate 62 slides upward, it will squeeze the spring 61 to generate a reaction force. The elastic coefficient generated by the spring 61 is fixed, so the force applied to the card plate 62 is also fixed.

[0035] Working principle: When using this device, first place the SMT soft board that needs to be dried on a special drying tray, and then start the electric telescopic rod 52, thereby driving the U-shaped plate 51 to slide longitudinally on the outer wall of the conveyor frame 1. During the longitudinal sliding process, the U-shaped plate 51 will drive the sliding rod 53 to squeeze the inner wall of the slide groove 501, thereby driving the transmission plate 54 to slide horizontally on the inner wall of the conveyor frame 1. When the transmission plate 54 slides horizontally, it will drive the splint 55 to move synchronously, so that the two sets of splints 55 open and close synchronously.

[0036] When the two sets of splints 55 are opened and closed to the appropriate size, the drying tray is inserted into the inner wall of the splint 55, so that a certain gap is maintained between the bottom of the drying tray and the conveyor 2, ensuring air circulation and making the drying of the SMT soft board more uniform. During the insertion process, the drying tray will squeeze the inclined surface of the card plate 62, causing the spring 61 to contract, thereby driving the card plate 62 to slide to the inner wall of the splint 55, thereby releasing the limit on the drying tray. When the drying tray is inserted into the inner wall of the splint 55, the contracted spring 61 will generate a reaction force, thereby making the card plate 62 fit against the drying tray, limiting the drying tray, reducing the jitter that may occur during the transportation process, and improving the stability during transportation.

[0037] Then, the conveyor 2 is started. When the conveyor 2 is in operation, the pushing plate 56 is driven to circulate. When the pushing plate 56 circulates, the drying tray inserted in the inner wall of the clamping plate 55 is pushed to slide on the conveying wheel 63.

[0038] Slide into the dryer 3, which can dry the SMT soft board. After the drying is completed, the conveyor 2 will transport the drying plate to the other end of the conveyor 2 to complete the drying process of the SMT soft board.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
