Background

In the manufacturing process of a printed circuit board, a subsequent baking process is usually performed on the board after a specific process step is completed. For example, after coating the surface of the printed circuit board, the board is baked to complete the process of making the coating layer. During the baking process, it is usually necessary to hold the board body of the printed circuit board by a clamp to convey the printed circuit board to a baking apparatus for a baking process. However, after the baking process is finished, the jig is often left with dirt such as paint from the board, so that the next baking process using the jig is continued after the dirt on the jig is removed, so as to prevent the dirt on the jig from contaminating the printed circuit board to be subsequently clamped. Generally, the clamp is mounted on the conveying rail during the baking process of the board, so that the clamp must be detached from the conveying rail to perform the cleaning process when the clamp is to be cleaned, and the clamp must be mounted back on the conveying rail after the cleaning process is completed.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, an embodiment of the baking apparatus 100 of the present invention is shown, in which the baking apparatus 100 is adapted to be used with a plurality of jigs 200 and a coating device 300, so that after a plurality of boards 400 (such as printed circuit boards) are coated with a coating material by the coating device 300, the boards 400 are clamped by the jigs 200 and baked in the baking apparatus 100, and the jigs 200 not clamping the boards 400 can be cleaned after the baking process is finished, so as to remove dirty components such as the coating material on the jigs 200. Specifically, the baking apparatus includes a baking box 1, an operation device 2, a clamp transferring device 3, a clamp lifting device 4, a clamp cleaning device 5 and a temperature control device 6, and the specific embodiment thereof will be described later.

The baking oven body 1 is, for example, a tunnel type baking oven, and has an inlet end 11 for feeding the plate 400 and an outlet end 12 for taking out the plate 400 after the baking process of the plate 400 is completed. The baking oven 1 has openings at the inlet end 11 and at the outlet end 12, which are not shown in detail. In this embodiment, the coating device 300 is disposed outside the baking oven 1 and corresponds to the position of the feeding end 11, and the baking process of the plate 400 and the cleaning process of the jig 200 are performed in the baking oven 1.

The control device 2 is a system formed by a computer and other control units, and is a control center of the baking apparatus 100, and an operator can control the baking apparatus 100 to perform various process procedures.

The clamp transfer device 3 is mainly disposed on the top side in the baking box body 1 and includes a guide rail 31. The guide rail 31 is adapted to detachably mount the clamp 200 thereon, and can be operated under the control of the operating device 2, so that the clamp 200 can move from the feeding end 11 to the discharging end 12 or from the discharging end 12 to the feeding end 11 in the baking oven box 1. In this embodiment, the guide rail 31 has an input section 311 and an output section 312, the input section 311 and the output section 312 are connected to form a continuous path, and the output section 312 is located above the input section 311. The gripper 200 is loaded in the input section 311 mainly from the feeding end 11 to the discharging end 12 of the baking oven 1, and the gripper 200 is loaded in the output section 312 mainly from the discharging end 12 to the feeding end 11 of the baking oven 1, so as to realize continuous circulation of the gripper 200. In addition, in this embodiment, the end of the guide rail 31 corresponding to the feeding end 11 extends out of the baking oven 1 and corresponds to the position of the coating device 300, so that the plate 400 can be conveyed to the clamp 200 at the feeding end 11 after being coated with the coating material on the surface by the coating device 300, and the plate 400 enters the baking oven 1 from the feeding end 11 along the input section 311 of the guide rail 31 after being clamped by the clamp 200 for the baking process. Since the guide rails 31 form a continuous path, after the board 400 is taken out from the discharging end 12 after the baking process, the clamps 200 that do not clamp the board 400 can be returned from the discharging section 312 to the feeding end 11 for recycling. In addition, since the input section 311 and the output section 312 of the guide rail 31 are configured to be stacked in the height direction, the planar occupation space of the toasting carriage 1 can be effectively reduced. Of course, the above-mentioned embodiment of the guide rail 31 is an example of the present embodiment, and the implementation form thereof can be adjusted as needed, and is not limited to the above-mentioned contents.

The jig lifting device 4 is disposed in the baking oven 1, and is controlled by the control device 2 to guide the lifting and lowering movement of the jig 200 loaded on the guide rail 31, so as to remove the jig 200 from the guide rail 31 and guide it into the jig cleaning device 5 for cleaning, and further, to guide the cleaned jig 200 back to the guide rail 31. In this embodiment, the fixture lifting device 4 is preferably disposed in the baking oven chamber 1 near the feeding end 11, and can be implemented by, for example, a vertical guide rail and other mechanisms, which are not illustrated in detail in this embodiment and are not limited to a specific embodiment.

The fixture cleaning device 5 is used for cleaning the fixture 200, and includes a cleaning tank 51 and an air outlet unit 52, which are disposed in the baking oven 1. The cleaning tank 51 may receive the jig 200 after the jig 200 not holding the plate 400 is guided to be lowered by the jig lifting device 4, and may clean the jig 200 by at least one of immersing the jig 200 in a chemical solution to remove an unclean component, washing the surface with clean water, and blowing the surface with high pressure air. Specifically, the cleaning tank 51 is located in the baking oven body 1 adjacent to the feeding end 11, and has a first processing tank 511, a second processing tank 512 and a third processing tank 513 which are isolated from each other and sequentially arranged from the feeding end 11 to the discharging end 12. The first treatment tank 511 is adapted to contain a chemical solution for cleaning the plate body 400, the second treatment tank 512 is adapted to contain clean water for cleaning the plate body 400, and the third treatment tank 513 contains the air outlet unit 52, wherein the chemical solution is, for example, a chemical agent capable of removing a coating material stained on the jig 200. The cleaning process of the jig 200 is to place the jig 200 in the first processing tank 511 to remove the dirty components by the chemical solution, then place the jig 200 in the second processing tank 512 under the driving of the guide rail 31 and the jig lifting device 4 to clean the plate 400 by the clean water, and finally place the jig in the third processing tank 513 by the guiding of the guide rail 31 and the jig lifting device 4 to blow off the residual moisture by the high pressure gas generated by the air blowing unit 52. Accordingly, the dirty components contaminated after the plate 400 is clamped by the clamp 200 can be effectively removed according to the above cleaning procedure. However, the cleaning process of the jig 200 may be performed by a process different from the above process, for example, some steps may be omitted or other auxiliary cleaning processes may be added, so that the embodiment of the jig cleaning apparatus 5 and the specific cleaning process of the jig 200 may be adjusted as needed, and the process sequence or process method for disposing the first processing bath 511, the second processing bath 512 and the third processing bath 513 is not limited.

The temperature control device 6 is installed in the baking box 1 and controlled by the control device 2 to adjust the temperature in the baking box 1, so that the plate 400 or the cleaned clamp 200 is baked in the baking box 1. Specifically, the temperature control device 6 can cooperate with components not shown in the drawings, such as a heater, a temperature sensor, and a control circuit, to realize the functions thereof, and is not limited to a specific implementation. In addition, the cleaning tank 51 may be provided with a heater, a temperature sensor, and the like as needed, and the temperature control device 6 is not limited to be provided only in the baking oven 1.

With reference to fig. 1 to 3, the operation of the baking apparatus 100 is described below.

First, as shown in fig. 1, the baking process of the plate 400 is that after the plate 400 is coated with the coating material on the surface by the coating device 300, the plate 400 is transported to the feeding end 11 of the guide rail 31 by a transport mechanism not shown in the figure and is clamped by the clamp 200, the plate 400 and the clamp 200 can enter the baking box 1 from the feeding end 11 of the baking box 1 along the input section 311 of the guide rail 31 and are gradually transported to the discharging end 12 along the path of the guide rail 31, during the transportation process, the plate 400 can be baked in the high temperature environment in the baking box 1 to complete the baking process, after reaching the discharging end 12, the plate 400 having completed the baking process can be unloaded, and the clamp 200 not clamping the plate 400 can return to the feeding end 11 along the output section 312 of the guide rail 31, for continuous recycling. In the above process, since the baking process is focused on the plate 400, the jig cleaning device 5 and the jig lifting device 4 are substantially in the non-operating state, and the cleaning bath 51 does not need to contain a cleaning solution such as a chemical solution or clean water.

On the other hand, the cleaning process of the jig 200 is performed along the guide rail 31 in a state where the jig 200 does not clamp the plate 400, as shown in fig. 2. Before the cleaning process is performed, the cleaning tank 51 must be properly prepared. After the clamp 200 is driven by the guide rail 31 and transmitted to the clamp lifting device 4, the clamp lifting device 4 lowers and raises the clamp 200 three times along the sequence of the first processing tank 511, the second processing tank 512 and the third processing tank 513, and drives the clamp 200 to advance by matching with the guide rail 31, so as to clean the clamp 200 in an automatic and continuous manner. The fixture 200 cleaned by the cleaning slot 51 can continue to advance to the discharge end 12 along the guide rail 31 and be dried in the baking box 1, and the temperature and time conditions for drying can be the same as or different from those for baking the plate 400, so as to thoroughly clean and dry the fixture 200. Since the cleaning process is performed in an automated manner and the jig 200 does not need to be removed from the guide rail 31 and remounted, the efficiency of performing the cleaning process on the jig 200 can be maximized. In addition, since the cleaning tank 51 is installed closer to the feeding end 11, the jig 200 can be baked for a long time in the baking oven 1 after being cleaned, thereby completely removing the residual moisture.

In summary, the baking apparatus 100 of the present invention can not only bake the board 400 through the cooperation of the clamp 200, but also clean the board from the guide rail 31 to the cleaning tank 51 guided by the clamp lifting device 4 when the clamp 200 does not clamp the board 400, and after the cleaning is completed, the board can be lifted back to the guide rail 31 guided by the clamp lifting device 4, and then bake the clamp 200 directly in the baking box 1 along the moving track of the guide rail 31. The above-mentioned automatic cleaning and baking processes for the fixture 200 not only can effectively reduce the time consumed for cleaning the fixture 200, but also can share the related devices for baking the board 400, thereby realizing the diversified process functions of the baking apparatus 100. Therefore, the toasting device 100 according to the present invention does achieve the object of the present invention.
