Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, and more specifically, to an automatic drying device for circuit boards. Background Art

[0002] After cleaning the circuit boards, they need to be dried. Existing dryers are designed to be relatively long to increase the time the boards spend passing through the dryer, thereby improving the drying effect. However, a long dryer takes up a significant amount of factory space. Furthermore, the boards are conveyed horizontally through the dryer via a conveyor belt during the drying process, hindering the removal of moisture from the boards and resulting in low drying efficiency. Utility Model Content

[0003] In order to overcome the disadvantage that circuit boards flow through the dryer in a horizontal posture, which is not conducive to draining moisture from the circuit boards and leads to low drying efficiency, the utility model provides an automatic drying device for circuit boards.

[0004] The technical solution of the utility model is:

[0005] A circuit board automatic drying equipment includes a shell and a bellows; a bellows is installed on the front and rear sides of the shell; it also includes an electric transmission wheel, a chain, a connecting plate, a receiving plate and a pipeline; at least four electric transmission wheels are installed on the shell; at least two chains are provided on the inner side of the shell, and the chains are connected to the corresponding electric transmission wheels; all chains are fixedly connected to a plurality of connecting plates; each connecting plate is fixedly connected to an inclined receiving plate; each shell is connected to a pipeline; a feed port is provided on the shell; a discharge port is provided on the shell; each receiving plate is provided with a transparent slot; each receiving plate is provided with a plurality of through holes.

[0006] Furthermore, a cover shell is included; a cover shell is fixedly connected to the lower side of each receiving plate.

[0007] Furthermore, a trumpet-shaped cavity is formed between the front portion of the cover shell and the corresponding connecting plate.

[0008] Furthermore, it also includes protrusions; each receiving plate is fixed with a plurality of protrusions.

[0009] Furthermore, it also includes a guide bar; a plurality of guide bars arranged obliquely are fixed to the front of each cover shell; and each cover shell is provided with at least two transparent grooves 2.

[0010] Furthermore, the guide strip is made of a heat-conducting material.

[0011] The beneficial effects are as follows: 1. The receiving plate drives the circuit board body to pass through the hot air flow in an inclined posture, so that the circuit board body can be moved and dried while draining, which is beneficial to improving the drying effect. In addition, the circuit board body moves upward inside the shell, that is, the device converts the horizontal movement of the circuit board body into vertical movement, which is beneficial to shortening the horizontal span of the dryer, thereby saving factory space;

[0012] Second, the cover guides clean water to the bottom of the inner side of the shell, thereby avoiding the problem of low drying efficiency caused by clean water on the upper circuit board body dripping onto the lower circuit board body. At the same time, the cover used to intercept clean water is also used to guide hot air to the bottom of the circuit board body, which is beneficial to improving the drying efficiency of the circuit board body;

[0013] 3. The hot air is diagonally directed upwards through the guide strips to prevent the hot air from flowing along the inner bottom surface of the cover, thereby avoiding interference with the drainage operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] A circuit board automatic drying equipment, such as Figures 1-4As shown, it includes an outer shell 1 and a bellows 2; a bellows 2 is installed on the front and rear sides of the outer shell 1, and the outer shell 1 is set to an alloy material; it also includes an electric transmission wheel 3, a chain 4, a connecting plate 5, a receiving plate 6 and a pipe 7; four electric transmission wheels 3 are installed on the outer shell 1; two chains 4 are provided on the inner side of the outer shell 1, and the chains 4 are connected to the corresponding electric transmission wheels 3; all chains 4 are bolted together with a number of connecting plates 5, and the connecting plates 5 are set to an alloy material; each connecting plate 5 is bolted to an inclined receiving plate 6; each outer shell 1 is fixed with a pipe 7; a feed port 91 is provided on the outer shell 1, and the circuit board 8 body is transported from the feed port 91 to the corresponding receiving plate 6 through an external conveying mechanism; a discharge port 92 is provided on the outer shell 1; each receiving plate 6 is provided with a transparent groove 93; each receiving plate 6 is provided with a number of through holes 94.

[0022] A cover shell 9 is also included; a cover shell 9 is welded to the lower side of each receiving plate 6, and the water droplets are intercepted by the cover shell 9.

[0023] A trumpet-shaped cavity is formed between the front portion of the cover 9 and the corresponding connecting plate 5 , which can guide air to the bottom of the circuit board 8 body.

[0024] It also includes protrusions 10; each receiving plate 6 is fixed with a plurality of protrusions 10.

[0025] The front of each housing 9 is welded with a plurality of guide strips 11 arranged obliquely; each housing 9 is provided with two through grooves 95 .

[0026] The guide strip 11 is made of a heat-conducting material and can absorb heat in the air.

[0027] First, manually connect the external air inlet pipe to the front bellows 2, and connect the external air outlet pipe to the rear bellows 2, and deliver hot air to the front bellows 2 through the external air inlet pipe, and the front bellows 2 delivers hot air to the inside of the shell 1 from front to back, and draws air to the rear bellows 2 through the external air outlet pipe, so that the air inside the shell 1 flows into the external air outlet pipe through the rear bellows 2, so that the hot air passes through the shell 1 from front to back, and starts the electric transmission wheel 3, which drives the chain 4 to move, and the chain 4 drives the connecting plate 5 to move, and the connecting plate 5 drives the receiving plate 6 to perform a circumferential circulation motion. In this process, the circuit board 8 to be dried is driven to move by the external conveying mechanism, so that the circuit board 8 to be dried passes through the feed port 91, and the circuit board 8 to be dried is placed on the bottom receiving plate 6 on the right. Since the receiving plate 6 is tilted, the circuit board 8 is also tilted after being placed in the receiving plate 6, and then The receiving plate 6 drives the circuit board 8 body to move upward, so that the circuit board 8 body passes through the convective hot air, and the circuit board 8 body is dried by the hot air. In the process of the circuit board 8 body moving upward in an inclined state, the water on the surface of the circuit board 8 body will flow obliquely downward and flow into the bottom of the shell 1 from the transparent groove 1 93, and then be discharged from the pipe 7, which is beneficial to improving the drying efficiency. When the receiving plate 6 drives the circuit board 8 body to move to the left of the discharge port 92, the circuit board 8 body is taken out by the external conveying mechanism to complete the drying operation. When in use, the circuit board 8 body is driven by the receiving plate 6 to pass through the hot air flow in an inclined posture, so that the circuit board 8 body can be drained while moving and drying, which is beneficial to improving the drying effect. In addition, the circuit board 8 body moves upward on the inside of the shell 1, that is, the device converts the horizontal movement of the circuit board 8 body into vertical movement, which is beneficial to shortening the horizontal span of the dryer, thereby saving factory space.

[0028] During the upward movement of the circuit board 8 body driven by the receiving plate 6, some of the clean water remaining on the circuit board 8 body will also drip from the through hole 94, which is beneficial to improving the drainage effect. In order to prevent the clean water on the upper circuit board 8 body from dripping onto the lower circuit board 8 body, a cover shell 9 is set under the receiving plate 6. After the clean water passes through the through hole 94, it will drip onto the cover shell 9, and the clean water will be guided to the inner bottom of the outer shell 1 through the cover shell 9, thereby avoiding the problem of low drying efficiency caused by the clean water on the upper circuit board 8 body dripping onto the lower circuit board 8 body.

[0029] After the circuit board 8 body is placed on the inner side of the receiving plate 6, the circuit board 8 body is lifted up by the protrusion 10, that is, a gap is formed between the circuit board 8 body and the receiving plate 6. When the receiving plate 6 drives the cover shell 9 to move upward to the hot air flow area, the hot air will flow into the cover shell 9, and the hot air will be guided to the through hole 94 through the cover shell 9, and then flow into the gap between the circuit board 8 body and the receiving plate 6 from the through hole 94, drying the bottom of the circuit board 8 body, which is beneficial to improving the drying effect. When in use, the cover shell 9 used to intercept clean water is also used to guide the hot air to the bottom of the circuit board 8 body, which is beneficial to improving the drying efficiency of the circuit board 8 body.

[0030] When the hot air flows inside the cover 9, it will interfere with the clean water flowing along the inner bottom surface of the cover 9, thereby affecting the drainage operation. Therefore, a guide strip 11 is set at the inner bottom of the cover 9. When the hot air is blown to the inside of the cover 9, the hot air is diagonally guided upward by the guide strip 11 to prevent the hot air from flowing along the inner bottom surface of the cover 9, thereby avoiding interference with the drainage operation. After the clean water is intercepted and blocked by the guide strip 11, it flows out from the transparent groove 2 95 to the inner bottom of the outer shell 1, and is finally discharged through the pipe 7.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, based on the idea of ​​the present application, there may be changes in the specific implementation methods and application scope.
