Description

Technical Field

[0001] The utility model belongs to the technical field of drying machines, and in particular relates to a drying machine for conductive slurry coating. Background Art

[0002] When drying the conductive slurry coating on the surface of the workpiece, the existing dryers often use the direct exhaust method of hot air, that is, using a fan to blow air to the heater, blowing the hot air into the drying box, and using the hot air to dry the conductive slurry coating. However, this method relies solely on the high temperature drying efficiency of hot air and has low efficiency; there is also a method of blowing hot air directly onto the surface of the conductive slurry coating, but since the blowing range of a single fan is limited, it is often necessary to set up multiple fans to blow hot air to the coating from different angles, which will increase manufacturing costs. Utility Model Content

[0003] The purpose of the utility model is to provide a drying machine for conductive slurry coating to solve the problem of low drying efficiency of the existing drying machine for conductive slurry coating.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A drying machine for conductive slurry coating, comprising a chassis and a fan assembly, a heating net, a placement rack and a guide assembly arranged in the chassis from bottom to top. Two partitions are symmetrically fixedly installed in the chassis, and the upper and lower ends of the two partitions do not contact the upper and lower ends of the chassis. Circulation channels are formed between the two partitions and the chassis. The guide assembly includes two guide plates symmetrically slidably connected to the inner sides of the two partitions. The bottoms of the two guide plates are provided with guide grooves, and the guide directions of the two guide grooves are inclined downward.

[0006] Preferably, it also includes two cabinet doors symmetrically connected to one side of the cabinet and a diverter rack fixedly connected to the top of the cabinet.

[0007] Preferably, two T-slots are provided in the chassis, and a sliding rod is fixed through each of the two guide plates. One end of the two sliding rods slides in the two T-slots respectively, and a slide is fixedly connected between the other ends of the two sliding rods, and a limiting mechanism is provided on the slide.

[0008] Preferably, the limiting mechanism includes two clamping rods symmetrically slidably connected to the slide and a plurality of clamping holes opened on two partitions and slidingly matched with the clamping rods. A guide rod is slidably connected to the slide, and a pressing rod is fixedly installed on the top of the guide rod. Connecting rods are rotatably connected between both ends of the pressing rod and the two clamping rods, and a spring is fixedly connected between the pressing rod and the slide.

[0009] Preferably, the fan assembly includes a motor fixedly connected to the bottom of the chassis and fan blades fixedly connected to the output shaft of the motor.

[0010] Preferably, an activated carbon filter is slidably connected in the circulation channel between the chassis and the partition, and a slide groove cooperating with the activated carbon filter is provided on the chassis and the partition, and one end of the activated carbon filter slides through the chassis.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The utility model is provided with a guide plate, and hot air is blown upward from the bottom of the placement rack to dry the conductive slurry coating on the bottom of the workpiece with hot air. At the same time, part of the hot air directly passes through the placement rack and rises to the bottom of the guide plate. The hot air is turned and tilted downward along the guide groove of the guide plate, thereby drying the conductive slurry coating on the top and side of the workpiece with hot air. At the same time, the air is circulated and blown in the chassis through the circulation channel for heating, so that each surface of the workpiece is dried with hot air and at high temperature by a single fan, thereby improving the drying efficiency.

[0013] (2) The utility model is provided with a slide, which drives the two slide bars to slide up and down, thereby driving the two guide plates to slide up and down, thereby controlling the blowing range of the hot air when it is turned, so that the hot air can be blown directly onto the conductive slurry coating on the surface of the workpiece as much as possible after being turned, thereby reducing heat loss and improving drying efficiency.

[0014] (3) When the above-mentioned slide slides, the two connecting rods drive the two clamping rods to slide toward the middle by pressing the pressing rod. At the same time, the pressing rod compresses the spring, causing the two clamping rods to slide out of the clamping hole. At this time, the slide can be slid up and down to drive the guide plate to slide. When it moves to the set height, the pressing rod is released. Under the elastic force of the spring, the pressing rod rises, causing the connecting rod to push the clamping rod to be reinserted into the clamping hole, thereby completing the adjustment of the slide height. The operation is simple and efficient.

[0015] (4) The present invention is provided with an activated carbon filter. The hot air drying process will take away the moisture in the conductive slurry coating. When the hot air circulates in the chassis and passes through the activated carbon filter in the circulation channel, the activated carbon filter will dry the air to improve the drying efficiency. At the same time, the activated carbon filter can also absorb some harmful gases. In addition, the activated carbon filter is installed by sliding in a slide groove, which is easy to replace.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-Figure 5 As shown, the utility model provides the following technical solutions:

[0024] A dryer for conductive slurry coating, comprising a chassis 1 and a fan assembly, a heating net 18, a placement rack 11, and a guide assembly sequentially arranged in the chassis 1 from bottom to top. Two partitions 3 are symmetrically fixedly installed in the chassis 1, and the upper and lower ends of the two partitions 3 do not contact the upper and lower ends of the chassis 1. Circulation channels are formed between the two partitions 3 and the chassis 1. The guide assembly includes two guide plates 6 symmetrically slidably connected to the inner sides of the two partitions 3. The bottoms of the two guide plates 6 are each provided with a guide groove, and the guide direction of the two guide grooves is inclined downward;

[0025] The chassis 1 further comprises two doors 2 symmetrically connected to one side of the chassis 1 and a diverter rack 7 fixedly connected to the top of the chassis 1 .

[0026] Based on the above disclosed structure, when performing the drying operation of the conductive paste coating:

[0027] The workpiece coated with the conductive slurry coating is placed on the placement rack 11, and then the two box doors 2 are rotated and closed, and the fan assembly is started to make the air between the two partitions in the chassis 1 rise, and at the same time the heating net 18 is energized so that the air is heated by the heating net 18 when it rises, thereby generating hot air. The placement rack 11 is preferably provided with a plurality of through holes, and the hot air is blown directly to the bottom of the workpiece through the through holes to dry the conductive slurry coating on the bottom of the workpiece. The hot air on both sides of the workpiece directly rises through the through holes on the placement rack 11 until the hot air reaches the bottom of the guide plate 6, and then the hot air flows along the guide groove at the bottom of the guide plate 6, so that the hot air on both sides finally flows along the guide groove. It is blown downward at an angle toward the middle, so that the hot air is blown directly onto the conductive slurry coating on the top and sides of the workpiece, thereby drying the conductive slurry coating on the top and sides with hot air. Then, the fan assembly continues to work, so that the air between the two partitions 3 continues to rise. When the air rises to the top, it is diverted to both sides by the diverter rack 7, and flows from the top of the two partitions 3 into the circulation channels on both sides. Then, the air descends from the circulation channel and is blown out again from the bottom of the partition 3 by the fan assembly, so that the air is circulated and heated in the chassis 1, so that the conductive slurry coating on the surface of the workpiece can be dried with hot air and at high temperature at the same time, with high efficiency.

[0028] In addition, in order to make the hot air blow directly onto the conductive slurry coating on the surface of the workpiece as much as possible after being diverted, the following structure is preferably provided:

[0029] Two T-slots 14 are provided in the chassis 1. Slide rods 15 are fixed through the two guide plates 6. One end of the two slide rods 15 is respectively slidably fitted in the two T-slots. The other ends of the two slide rods 15 are fixedly connected to a slide 13. A limiting mechanism is provided on the slide 13.

[0030] The limiting mechanism includes two clamping rods 4 symmetrically slidably connected to the slide 13 and a plurality of clamping holes 5 opened on the two partitions 3 and slidingly matched with the clamping rods 4. A guide rod 19 is slidably connected to the slide 13, and a pressing rod 9 is fixedly installed on the top of the guide rod 19. Connecting rods 10 are rotatably connected between both ends of the pressing rod 9 and the two clamping rods 4, and a spring 8 is fixedly connected between the pressing rod 9 and the slide 13.

[0031] As can be seen from the above, the height of the guide plate 6 can control the blowing range of the hot air after it is turned. Therefore, when adjusting the height of the guide plate 6, first press the pressing rod 9 to make the pressing rod 9 close to the slide 13, so that the guide rod 19 slides and extends into the slide 13, and at the same time, the pressing rod 9 compresses the spring 8 on the slide 13, and the two ends of the pressing rod 9 drive one end of the two connecting rods 10 to approach the slide 13, so that the other ends of the two connecting rods 10 respectively drive the two clamping rods 4 to slide toward the middle, so that the two clamping rods 4 respectively slide out of the clamping holes on the two partitions 3, so that the slide 13 can be slid up and down between the two partitions 3, thereby driving the two slide rods 15 to slide in the two T-slots, thereby driving the two guide plates 6 to slide up and down on the inner side of the two partitions 3, so as to adjust the height of the guide plate 6;

[0032] When the guide plate 6 moves to the set height, the slide 13 drives the two clamping rods 4 to move to the outside of the corresponding clamping hole 5, and then the pressing rod 9 is released. At this time, under the elastic force of the spring 8, the pressing rod 9 moves away from the slide 13, so that the two ends of the pressing rod 9 drive one end of the two connecting rods 10 away from the slide 13, so that the other ends of the two connecting rods 10 respectively drive the two clamping rods 4 to slide to both sides, so that the two clamping rods 4 are inserted into the clamping hole 5 again, thereby realizing the limitation of the slide 13 and fixing the height of the guide plate 6.

[0033] Preferably, the fan assembly includes a motor 17 fixedly connected to the bottom of the chassis 1 and a fan blade 16 fixedly connected to the output shaft of the motor 17. Based on this, the fan blade 16 is driven to rotate by the motor 17, so that the fan blade 16 drives the air to rise through the heating network 18 for heating, and at the same time, the air pressure below the fan blade 16 is reduced, thereby sucking the air in the two circulation channels on both sides into the bottom of the fan blade 16, thereby facilitating air circulation in the chassis 1.

[0034] Furthermore, an activated carbon filter 12 is slidably connected in the circulation channel between the chassis 1 and the partition 3. Both the chassis 1 and the partition 3 are provided with a slide groove that cooperates with the activated carbon filter 12, and one end of the activated carbon filter 12 slides through the chassis 1. Based on this, the hot air drying process will take away the moisture in the conductive paste coating, so that the air enters the circulation channel for circulation under the action of the above-mentioned fan assembly. When the air carrying moisture passes through the activated carbon filter 12, the activated carbon filter 12 will absorb the moisture in the air, so that the air remains dry, thereby improving the drying efficiency. At the same time, the activated carbon filter 12 can also absorb some harmful gases and reduce the emission of harmful gases. In addition, the activated carbon filter 12 is slidably installed between the chassis 1 and the partition 3 through the slide groove, and one end of the activated carbon filter 12 slides through the chassis 1, so that the activated carbon filter 12 can be directly pulled out and replaced from one side of the chassis 1, which is convenient to operate and highly efficient.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
