Description

Technical Field

[0001] The utility model relates to the technical field of a humidifying device, in particular to a humidifying machine mainly used for humidifying and curing a circuit board. Background Art

[0002] At present, in the production process, some products need to be humidified and cured. For example, after the welding of electrical components on the substrate of the circuit board of an electrical appliance is completed, in order to protect the welding points of the welding feet of the electrical components, some need to be coated with insulating glue (such as silica gel) at the welding points of the welding feet. The insulating glue often needs to absorb moisture before curing. If the circuit board coated with insulating glue is placed in the air, the humidity in the air is unstable and uncontrollable, which will affect the timely progress of the subsequent process. For this reason, people often place the circuit board coated with insulating glue in a humidifier in sequence. The humidifier includes a box body, a heating device and a humidifying device arranged in the box body. The box body is also provided with support plates that are sequentially spaced up and down to form a multi-layer structure for the circuit boards coated with insulating glue to be placed in sequence. By using such a humidifier, the curing speed of the insulating glue can be accelerated by adjusting the temperature and humidity to improve production efficiency and ensure curing quality. However, since the gluing operation is often completed on the assembly line, the soldered circuit boards are usually transferred to the next process by a conveyor belt. In order to add a humidification process, it is necessary to manually transfer the glue-coated circuit boards to the support plates in the box in turn. After humidification, they are transferred to the conveyor belt in turn. Obviously, this humidification method is time-consuming and labor-intensive, and the concentrated entry into the box will still affect the timely progress of subsequent processes to a certain extent, so it needs to be further improved.

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 6 As shown, the humidifier in this embodiment is mainly used to humidify circuit boards (of course, other products can also be humidified as needed). It includes a box body 1, a receiving platform 2, a discharging platform 3, and a heating device 4 and a humidifying device 5 located in the box body, wherein the left and right opposite side walls of the box body 1 are provided with an inlet 11 for the carrier to enter and an outlet 12 for the carrier to be output. The carrier 100 in the figure is designed in the shape of a disc to carry the circuit board to be humidified. It can also be designed as a plate-like body when necessary, that is, it is not limited to a disc structure. The receiving platform 2 is connected to the inlet 11 of the box body 1 and corresponds to the bracket 64 at the bottom of the ascending channel described below. The discharging platform 3 is connected to the outlet 12 of the box body 1 and corresponds to the bracket 64 at the bottom of the descending channel described below. The arrangement of the receiving platform 2 and the discharging platform 3 is conducive to the carrier 100 being smoothly fed into the inlet 11 and output from the outlet 12 of the box body. In this embodiment, in order to connect with the conveyor belt on the production line and make the carrier 100 more convenient to move, the bottom of the box body 1, the bottom of the receiving platform and the bottom of the unloading platform jointly form a horizontal channel C for the conveyor belt to pass through. Specifically, the bottom plate 13 at the bottom of the box body is bent to form the middle section, and the left and right sections of the horizontal channel are formed between the bottom feet of the unloading platform 3 and the bottom feet of the receiving platform 2. In this way, when the circuit board after the previous welding process is sent to the receiving platform 2 by the conveyor belt, it can be placed on the receiving platform 2 by manual or mechanical hands, and the products that do not need to be humidified are directly sent to the next process by the conveyor belt.

[0021] In order to complete the humidification operation, an ascending channel A for the carrier to move upward and a descending channel B for the carrier to move downward are separated in the above-mentioned box body 1. Four sprocket-chain groups 6 are placed in the ascending channel A and the descending channel B. The four sprocket-chain groups 6 are respectively located at the four corners of their respective channels. Each sprocket-chain group 6 includes an upper sprocket 61 located at the top of the corresponding channel, a lower sprocket 62 located at the bottom of the corresponding channel, and a chain 63 wound around the corresponding upper and lower sprockets. Brackets 64 that can jointly support the carrier are fixed at intervals on each chain 63. At the same time, a bracket 64 is installed on the box body. There is a motor 7 that can drive each sprocket-chain group to rotate synchronously and a transmission mechanism 8 that makes the sprocket-chain groups in the ascending channel and the descending channel rotate in reverse. Specifically, the transmission mechanism 8 includes a first gear group 81, a second gear group 82 and a third gear group 83, wherein the first gear group 81 and the second gear group 82 adopt bevel gear groups, which are respectively located on both sides of the motor 7, and the input shafts of the first gear group 81 and the second gear group 82 are respectively linked with the output shaft of the motor 7, and the output shafts of the first gear group 81 and the second gear group 82 are the corresponding upper sprocket shafts 65. There are also two third gear sets 83, each third gear set 83 is located between adjacent sprocket-chain sets 6 between the ascending channel A and the descending channel B, each third gear set 83 is composed of two mutually meshing pinion gears, and each pinion gear is installed on the upper sprocket shaft 65 of the corresponding group, so that the rotation of the motor 7, through the transmission of the first gear set 81, the second gear set 82 and the third gear set 83, drives the sprocket-chain sets in the ascending channel and the descending channel to rotate synchronously, and the sprocket-chain sets in the ascending channel and the descending channel rotate in opposite directions, thereby satisfying the ascending and descending of the carrier.

[0022] At the same time, a first driving mechanism 91, a second driving mechanism 92, and a third driving mechanism 93 are also configured. Specifically, the first driving mechanism 91 can move the carrier from the entrance 11 to the bracket 64 at the bottom of the ascending channel. It is located at the bottom of the above-mentioned box body 1. The first driving mechanism 91 can be set up as one and placed in the middle position of the bottom of the box body. However, considering the arrangement of the conveyor belt and the stability of the force, the first driving mechanism 91 is arranged with two, which are respectively located at the front and rear sides of the horizontal channel C. Each first driving mechanism 91 includes a first cylinder 911, a piston rod of the first cylinder, and a second cylinder 912. A fixed first push rod 912 and a first push plate 913 fixed on the first push rod, the piston rod of the first cylinder 911 can move back and forth from the entrance to the exit of the box, the first push rod 912 is arranged in parallel with the piston rod of the first cylinder, the first push plate 913 is located at the upstream position of the carrier outside the entrance and can push the carrier through the entrance 11 with the first push rod and be placed on the bracket 64 at the bottom of the ascending channel. In the figure, in order to ensure smooth movement, a guide hole 21 extending along the moving direction of the push rod is opened on the above-mentioned receiving platform 2, and the first push plate 913 extends into the guide hole 21.

[0023] The third driving mechanism 93 is used to move the carrier 100 on the bracket 64 at the bottom of the descending channel B out of the outlet 12 of the box body. It can be set separately, but considering the compactness of the overall structure and the manufacturing cost of the humidifier, the third driving mechanism 93 and the first driving mechanism 91 share the same cylinder and push rod, that is, the third driving mechanism 93 is also designed with two, each of which includes the first cylinder 911, the first push rod 912 and the second push plate 931 fixed on the first push rod 912 (see Figure 6 The second push plate 931 is fixed on the right end of the first push rod 912, and the first push plate 913 is fixed on the left end of the first push rod 912). The second push plate 931 extends into the box body 1 and can push the carrier 100 on the bracket at the bottom of the descending channel B to move out of the outlet 12 along with the first push rod 912.

[0024] The above-mentioned second driving mechanism 92 is used to move the carrier 100 on the bracket 64 at the top of the ascending channel to the bracket 64 at the top of the descending channel. It includes a second cylinder 921 and a third push plate 922 fixed on the piston rod of the second cylinder. The piston rod of the second cylinder 921 can also move back and forth from the inlet 11 of the box to the outlet 12 of the box. The third push plate 922 is located on the outer side of the carrier at the top of the ascending channel A and can push the carrier to move to the bracket of the descending channel B with the piston rod of the second cylinder 921. In the figure, in order to apply force evenly, there are two third push plates 922, which are respectively fixed on a movable plate 923 at intervals. The movable plate 923 is fixed on the piston rod of the second cylinder 921. In order to ensure the smooth movement of the movable plate 923, the two ends of the movable plate 923 are also respectively mounted on their own guide shafts 924. The guide shafts 924 are supported on the box 1 and are distributed parallel to the piston rod of the second cylinder 921.

[0025] The above-mentioned heating device 4 and humidifying device 5 can both adopt existing technologies. In the figure, the humidifying device 5 and the heating device 4 are respectively located at the front and rear sides of the box 1, and there are two groups of heating devices 4, which are distributed at intervals above and below. At the same time, a plurality of fans 10 are also arranged in the box to make the heated air flow quickly, so that the air temperature and humidity in the box are uniform, which is conducive to improving the curing speed and curing quality.

[0026] In order to meet the coordinated operation of different components, corresponding travel switches and / or position sensors are configured in the box. When the carrier reaches the corresponding position during movement, the corresponding travel switch and / or position sensor will be triggered. The signal of the travel switch and / or position sensor will be transmitted to the controller, and then the controller will control the start and stop of the corresponding cylinder and motor. Of course, corresponding switches and indicator lights are also configured to prepare for the start or stop operation and corresponding instructions when needed. These can be completed using the PLC controller or PC in the prior art, and the control system will not be described in detail here.

[0027] During use, when the position sensor or the stroke switch senses that there is a carrier on the receiving platform, the first cylinder is started, and the first push plate will push the carrier on the receiving platform from the entrance to the bracket at the bottom of the ascending channel, and then the motor is started. The motor will drive the sprocket-chain groups to operate, so that the carrier rises in the ascending channel. When it reaches the top, the position sensor or the stroke switch at the top senses the carrier, and the controller will start the second cylinder at the top, and the third push plate will push the carrier into the bracket at the top of the descending channel, and then it will be transported to the bottom of the descending channel by the bracket on the chain in the descending channel, and finally it will be pushed to the discharge platform by the second push plate and fall onto the conveyor belt. In this process, the rotation speed of the motor is controlled so that the carrier can just complete the humidification and curing operation required for the circuit board during the ascending and descending operation. Therefore, by using the humidifier in this embodiment, the circuit boards to be humidified can continuously enter the humidification box, and at the same time, the circuit boards that have been humidified can be continuously removed from the outlet and then continuously transported to the next process by the conveyor belt, thereby meeting the timely production requirements of the entire production line.
