Description

Furnace door adjustment method and device for panel oven

The invention relates to the structural configuration of a panel oven, in particular to a method and device for adjusting an oven door of a panel oven.

As we all know, the general production process of printed circuit boards or substrates (hereinafter referred to as boards) includes processes such as ink coating, drying, and baking on the boards. Among them, the baking process of the plate is mostly carried out in a tunnel oven or an oven with independent batch space.

Wherein, the tunnel oven has at least two channel openings for loading and discharging plates, and a plate channel communicates between the two channel ports. In more advanced tunnel-type ovens, multiple temperature-controlled compartments for standing, baking and cooling are separated between the plate loading and discharge channels, and communication channels are also formed between the temperature-controlled compartments. The channel opening of the plate channel. The boards waiting to be baked in the tunnel oven can be transferred step by step one by one, or in batches of multiple batches. Sequentially pass through the channel openings of each temperature-controlled compartment, and then move out of the oven through the channel openings of the discharge plates. In addition, in an oven with an independent batch space, usually there is only a single channel opening for the internal plate channel to communicate with the outside, so that the single channel port can be shared when loading and discharging plates.

Furthermore, the oven of the above type usually relies on a transmission element to carry the plate into and out of the oven through the passage opening. When the board is in the form of step-by-piece transfer, the transmission element can be a chain that can move in circles, and a plurality of clamps are arranged at intervals on the chain, and the clamps are used to clamp the board to make the board It can move into the channel of the panel through the above-mentioned channel opening in a hanging manner, and move out of the oven. In addition, when the plate is in the form of step-by-step transfer in batches, the transmission element can be executed A plurality of walking beams (walking beams) that can generate interactive motion for reciprocating and stepping batches of boards. In addition, the transmission elements for carrying boards into and out of the oven can also be other than the above-mentioned chains and crossing beams. Pushing, pulling or other equivalent mechanisms that can drive the plate to move in the plate channel.

In addition, there is a heater (such as an electric heating tube) inside the oven, which can be used to generate heat energy to adjust and control the oven or a part of the temperature control compartment of the oven to achieve the desired heating temperature, and then bake and dry plate. Because the oven communicates with the outside world through the channel openings for loading and discharging the plates; and, for ovens with multiple temperature-controlled compartments, the plate channels are also communicated with each other through the channel ports between the temperature-controlled compartments; generally In other words, the heat energy generated by the heater will flow outward through the above-mentioned passage openings, or overflow the heat energy to the adjacent temperature-controlling chambers through the passage openings of the above-mentioned temperature-controlling chambers, affecting the inside of the oven or its temperature-controlling chambers. The effect of standing, baking or drying the parts may cause the problem of excessively increasing the power consumption of the heater.

In order to overcome this problem, the more advanced ovens at present have been equipped with a movable furnace door at the above-mentioned channel opening. The furnace door is usually completely closed. When the parts are to enter another temperature-controlled cabin from one temperature-controlled cabin, the fully closed furnace door will be fully opened, and when the plate passes through the passage opening, the furnace door will be completely closed again, thereby effectively reducing the oven temperature. Inside, especially the heat energy loss of each temperature-controlled compartment.

It is also known that according to the current technology, because the above-mentioned step-by-step transfer of boards in batches, the time that must be kept at intervals during the transfer process is relatively longer than that of step-by-piece transfer of boards. Therefore, the above-mentioned movable method The oven door is more suitable for installation in ovens that move boards in batches, and can achieve ideal energy-saving benefits.

However, for an oven that moves boards one by one, because the interval between boards is relatively short, the moving efficiency of the boards is not affected. In the case of a certain situation, setting a movable furnace door at the above-mentioned passage opening, and then controlling the full opening or full closing of the passage opening, has no substantial benefit, and even cannot overcome the problems of heat loss and power loss.

Furthermore, since the area of the plate has a variety of different sizes and specifications Moreover, a single oven must be able to accept plates of various sizes for baking and drying at the same time. However, the above-mentioned tunnel-type ovens that are more suitable for installing movable furnace doors in batches to carry panels, their movable furnace doors only have the function of fully opening or fully closing the passage opening; when the movable furnace door fully opens the passage opening, And when the surface area of the plate is relatively smaller than the passage opening, there is a considerable open area between the edge of the plate and the passage opening, forcing the heat in the oven or each temperature control chamber to pass through the open surface. If the domain spills outward, it will also cause heat loss and power loss.

Therefore, no matter whether the boards are transferred one by one or in batches, the movable door installed in the existing oven cannot reduce the heat energy in the oven through the passage without hindering the passage of the boards. The channel opening is drained outwards, so it has become a technical subject to be improved.

In order to overcome the above-mentioned technical problems, the present invention inspires a unique idea, which is to regard the panel area as a part of the furnace door area, and create a movable furnace door that can control the opening of the movable furnace door according to the panel area specifications. The new technology of the area makes the opening area of the movable oven door as close as possible to the area of the plate, so as to improve the temperature of the existing oven or its various temperatures without hindering the movement of the plate through the passage opening. The heat in the control compartment is easy to escape through the passage opening or into the temperature control compartment on the adjacent side when the plate moves through the passage opening

In a further implementation, there are three frame sides of the access opening, and three door panels are correspondingly arranged, and the first opening area is presented when the three door panels are relatively far away from each other. The second opening area is presented when the three door panels are relatively close to the three end edges of the panels, and the third opening area is presented by the closing action of at least one of the three door panels.

In a further implementation, the moving directions of at least two door panels are located on the same coordinate axis. Wherein the coordinate axis can be a coordinate horizontal line.

In a further implementation, at least two of the door panels determine the second opening area according to a panel area specification of the panel.

In a further implementation, it also includes using a control unit, before controlling the multiple opening areas of the passage opening, an operator sets a panel area specification of the panel in the control unit, the The control unit controls a plurality of opening areas of the channel opening according to the area specification of the panel.

In order to implement the above method, another preferred embodiment of the present invention is to provide an oven door adjustment device for a panel oven, which is used to further disclose the The relevant structural details of forming a panel channel, disposing the transmission element and at least two movable door panels are used to control multiple opening areas of the channel opening.

According to the above, the technical effect of the present invention is to adjust the opening area of the channel opening according to the area specification of the plate to be baked, so as to reduce the heat energy in the oven from being lost through the channel opening or overflowing through the channel opening. To the temperature control compartment on the adjacent side, so as to maintain the required standing, baking or drying temperature in the oven or in each temperature control compartment, and reduce the power loss of the heater.

For this reason, please refer to Fig. 1a earlier, illustrate that the panel provided by the present invention The method for adjusting the oven door of an oven includes performing the following steps S1 to S4 in sequence:

Step S1: Plan the channel of the panel according to the area of the panel

Please refer to FIG. 2 and FIG. 3 together, which illustrate that the plate 30 has four edges, including a quadrilateral area surrounded by the top edge 30a, the double-sided edges 30b and 30c, and the bottom edge 30d, wherein the top The end side 30a and the bottom end side 30c are opposite sides, and the double-sided end sides 30b, 30d are opposite sides. A plate channel 11 for providing the plate 30 to move is planned in the oven 10. The plate channel 11 has at least one quadrangular channel opening 12, and the plate 30 can pass through the channel opening 12 in the oven 10. Displacement in the plate channel 11. The number of the passage openings 12 is different according to the structure of the oven 10, for example: the tunnel oven 10 has two passage openings 12 for loading and discharging the plates 30; The plate channel 11 has only a single channel opening 12 to communicate with the outside; in the oven 10 with multiple heating compartments, the multiple heating compartments in it are connected via the channel opening 12, that is to say, how many of the channel openings 12 are there? indivual.

Step S2: Configure transmission components

The channel opening 12 has four frame edges 12a, 12b, 12c, 12d, wherein the frame edge 12a is opposite to the frame edge 12c, the frame edge 12b is opposite to the frame edge 12d, and the frame edge 12a The frame side 12c is the adjacent side of the frame side 12b and the frame side 12d respectively. Take the frame edge 12a and configure a transmission element 40 for carrying the plate 30 into and out of the oven 10. In this implementation, the transmission element 40 can be a chain that can move in circles. A plurality of racks for clamping the boards 30 are configured, and clamps are arranged on the racks, so that the boards 30 can be carried step by step into and out of the oven in a hanging form. In addition, the transmission element 40 may also be a walking beam (not shown in the figure) that can generate interactive motion, and is used to hang the stepping carrying plate 30 in batches into and out of the oven.

Furthermore, when the transmission element 40 steps the carrying plate 30 into and out of the oven in a piece-by-piece or batch-hanging form, the frame edge 12a of the transmission element 40 may be located in the channel The top of the opening 12 , the plate 30 accepts the suspension of the transmission element 40 and enters and exits the oven 10 through the passage opening 12 . In this embodiment, the plate 30 is suspended by the transmission element 40 via its top edge 30a; The top frame edge 12a; the double-sided end edges 30b, 30c of the plate 30 correspond to the double-sided frame edges 12b, 12c of the passage opening 12; the bottom end edge 30d of the plate member 30 corresponds to the passage opening The bottom frame edge 12d of 12. In addition, when the transmission element 40 is a pushing or pulling mechanism capable of linear movement, or other equivalent mechanisms capable of supporting and moving panels, the position of the transmission element 40 is configured, It can also be any one of the remaining three frame sides (namely, the two-side frame sides 12b, 12c and the bottom frame side 12d) other than the top frame side 12a of the channel opening 12 .

Step S3: Configure the movable door panel

In the implementation shown in Fig. 2 to Fig. 8, only take the configuration of three movable door panels as an example for illustration, but the number of door panel configurations of the present invention is not limited thereby, in essence, the number of door panel configurations of the present invention can be at least There are two (detailed later).

As shown in Figure 3, when the transmission element 40 is configured on the frame edge 12a at the top of the passage opening 12, the remaining three frame edges of the passage opening 12 (i.e. both side frame edges 12b, 12c and the bottom frame edge 12d) are equipped with a movable door panel 20 respectively, so that the number of door panels is three in total. Wherein, the moving directions of the door panels 20 arranged on the two side frame sides 12b, 12c may be along the same coordinate axis, and the coordinate axis is the coordinate horizontal line 14 in practice. Furthermore, the moving direction of the door panel 20 disposed on the bottom frame 12 d may be along another coordinate axis, which is the coordinate vertical line 13 in practice.

Step S4: Control the opening area of the passage opening

The three door panels 20 are used to control the opening areas 23 of the channel opening 12 when the panels 30 enter and exit the oven 10 . The plurality of open areas 23 respectively provide and restrict the movement of the plate 30 through the passage opening 12 . A plurality of said opening area 23 comprises a first opening area 231 (as shown in Figure 2), a second opening area 232 (as shown in Figure 4) and a third opening area 233 (as shown in Figure 5 shown).

Wherein, the first opening area 231 is formed by the three door panels 20. This occurs when the maximum surface area of the passage opening 12 is opened relatively far away (as shown in FIG. 2 ). The second open area 232 is defined by the three door panels 20 according to the area specifications of the baked plate 30 , so that the second open area 232 can be positioned at the two-side end edges 30b of the plate 30 , 30c and bottom edge 30d are relatively close to each other (as shown in FIG. 4 ); therefore, the second open area 232 must be substantially smaller than the first open area 231 and relatively larger than that of the plate 30 area, so that the plate 30 can follow the second opening area 232 and smoothly pass through the passage opening 12 with the smallest area gap; that is, the second opening area 232 is based on the The area specifications of the panel 30 are determined. The third opening area 233 is presented by the closing action of at least one door panel 20 among the three door panels 20 (as shown in FIG. 5 ), so that the third opening area 233 is relatively smaller than the first opening area. 231 and the second opening area 232 , and the third opening area 233 is only used by the transmission element 40 to pass through the passage opening 12 , and restricts the plate 30 from passing through the passage opening 12 . In other words, the first open area 231>the second open area 232>the third open area 233>0.

In addition, a soft curtain 50 (as shown in FIG. 6 ) can be provided on the top frame 12a of the passage opening 12 to cover the third opening area 233 flexibly, but the soft curtain 50 allows the transmission The element 40 penetrates and moves through the passage opening 12, so that in the state of the third open area 233, the soft curtain 50 can further reduce the heat energy in the oven 10 through the third open area 233. The channel opening 12 drains outward.

In addition, please continue to refer to FIG. 1 b to further illustrate the comparison method of the open area including the control passage opening in the above step S4, including performing the following steps S41 to S43 in sequence. in:

Step S41: Set the area specification T1 of the full opening area of the channel opening

The oven 10 is pre-configured with a control unit 15 constructed using NC or PLC technology, and the oven 10 uses the control unit 15 to control the actuation timing of the three door panels 20 to control the passage opening 12 The first open area 231 , the second open area 232 and the third open area 233 . Further, the control In the manufacturing unit 15, the specification T1 of the fully open area of the channel opening 12 has been set in advance according to the predetermined specifications of the oven equipment.

Step S42: Obtain the panel area specification T2

In the above step S4, before the first opening area 231, the second opening area 232 and the third opening area 233 of the three door panels 20 are activated, the panel area specifications of the panel 30 waiting to be baked T2 can be obtained by one of the following steps S421 and S422, wherein:

Step S421: an operator sets the panel area specification T2 according to the actual area specification (such as length, width or area) of the panel 30 waiting to be baked, and presets the panel area specification T2 in the control unit 15 internal storage; the pre-set method can be directly input by the operator through the keyboard, or the control unit 15 can be connected to receive information on the area specification of the plate to be baked in a manufacturing execution system (MES) , are within the scope of application. or,

Step S422: Take an area measuring element 16 and install it on a plate 30 on the outside of the channel opening 12 at the feeding end of the oven 10 (as shown in FIG. 9 ); the area measuring element 16 It can be constructed by a laser measuring device or a charge-coupled device (CCD), and the plate area specification T2 of the baked plate 30 is detected through the area measuring element 16, and then stored in the control unit within 15.

Step S43: Comparing the panel area specifications T1 and T2

After the control unit 15 obtains the full-open area specification T1 of the channel opening and the panel area specification T2 according to the above-mentioned step S421 or step S422, it will compare them in order to pre-calculate and obtain the required first open area 231, the second The opening area 232 and the third opening area 233 are located at the actual distance between the coordinate vertical line 13 and the coordinate horizontal line 14 shown in FIG. 2 , and then the following step S44 is performed.

Step S44: Move the door panel to present the required opening area

The control unit 15 can further control the actuators 21 and 22 (as shown in FIG. 7 ) configured respectively of the three door panels 20 to actuate according to the actual distance obtained after comparing the area specifications in the above step S43, so as to drive the three doors. The door panel 20 moves synchronously to the desired first opening area 231, the second opening area 232 and the third opening area 233 Furthermore, the three door panels 20 can be moved synchronously from the initial state to the position of the first opening area 231, and the first opening area 231 can be adjacent to or equal to the position of the passage opening. Full open area specification 23a (as shown in Figure 2).

Subsequently, when the panel 30 is about to move through the channel opening 12, the control unit 15 commands the drivers 21, 22 to synchronously drive the three door panels 20 to move from the position of the first opening area 231 to the required second opening area. 232 position, in order to facilitate the plate 30 to move through the passage opening 12 through the second opening area 232, and then enter the oven, change the position of the temperature control compartment of the oven or exit the oven. It must be noted here that, in the state of the second open area 232 (as shown in FIG. 4 ), the three end edges (i.e., both sides) of the zigzag door edge formed around the three door panels 20 and the panel 30 The gap 23a formed between the end edges 30b, 30c and the bottom end edge 30d) can be minimized to prevent the heat energy in the plate channel 11 from being exposed to the outside when the plate 30 is stepping into and out of the oven or changing the temperature control cabin. Loss or overflow to the adjacent temperature-controlled cabin, to achieve the best effect of energy saving.

In addition, when the panel 30 is stationary and the passage opening 12 is not blocked by a panel, the control unit 15 can command at least one driver 21 or 22 to drive at least one of the three door panels 20 (such as the bottom door panel 20a) Directly move from the first opening area 231 position to the required third opening area 233 position, or move from the second opening area 232 position to the required third opening area 233 position, so as to completely close the The channel opening 12 prevents the heat energy in the plate channel 11 from being lost or spilled to the adjacent temperature-controlled compartment. At this time, the plate 30 cannot enter the oven through the channel port 12, change the position of the temperature-controlled compartment of the oven or discharge oven. Conversely, when there is a plate 30 to pass through the passage opening 12, the opening area 23 of the passage opening 12 will be adjusted from the third opening area 233 to the second opening area 232, so that the plate 30 can Through the channel opening 12. Wherein, whether the plate 30 passes through the passage opening 12 or not, the control unit 15 can be notified through a common sensing element (not shown) provided at or near the passage opening 12 , and will be described.

As shown in FIG. 7 , the three door panels 20 are respectively arranged on the three double-sided frame edges 12b, 12c and the bottom frame edge 12d of the passage opening 12, and the passage opening 12 is formed by a plate in the oven 10. The channel 11 (as shown in FIG. 3 ) is extended so that the panel channel 11 can communicate with the outside world through the channel opening 12 .

As shown in FIG. 3 , the oven 10 in this embodiment is a tunnel oven, and the tunnel oven 10 has at least two channel openings 12 for loading and discharging the plates 30 , especially including an inlet channel opening 121 and A discharge passage opening 122; In addition, the passage opening 12 can also include at least one temperature-controlled cabin passage opening 123 between the feed passage opening 121 and the discharge passage opening 122, so that the plate passage 11 can It is connected between the feed channel opening 121, the temperature control chamber channel opening 123 and the discharge channel opening 122, and there is a plate moving track 111 in the plate channel 11, and the plate 30 is along the The plate moving track 111 enters the inlet channel opening 121, and can move through the temperature control cabin channel opening 123 sequentially in the static, baking and drying isothermal cabins, and finally through the discharge The access port 122 moves out of the oven 10 .

Please combine Figure 7 and Figure 8, the top frame 12a of the channel opening 12 is equipped with a transmission element 40, and the plate 30 is carried by the transmission element 40 and enters and exits the oven 10 along the plate moving track 111. . The three movable door panels 20 are respectively arranged on the remaining three frame edges (i.e., the two-side frame edges 12b, 12c and the bottom frame edge 12d) of the passage opening 12, and are driven by at least one driver to operate on the When the plate 30 enters and exits the oven 10 , it regulates the multiple opening areas 23 of the channel opening 12 .

The three door panels 20 include a vertical door panel 20a and two side door panels 20b, wherein the vertical door panel 20a is slid on the bottom frame edge 12d of the passage opening 12 along a coordinate vertical line 13, and the two The lateral door panels 20b are respectively slidingly assembled on the two side frame sides 12b, 12c of the passage opening 12 along the coordinate horizontal line 14, and the vertical door panels 20a are located on the moving track 111 of the panel in practice. It is arranged alternately adjacent to the two side door panels 20b.

Furthermore, the vertical door panel 20a passes through a vertical drive 21 is driven to move along the coordinate vertical line 13, and then control the opening area 23. The vertical drive 21 includes a motor 211 and a transmission configuration of at least one screw 212 in implementation, and the screw 212 is driven by the motor 211 to rotate. Drive the vertical door panel 20a to move. The two lateral door panels 20b are displaced along the coordinate horizontal line 14 driven by at least one transverse driver 22, and then control the opening area 23. The horizontal slide rail 221, and the motor 222 that drives the lateral door panels 20b to slide relative to the multiple horizontal slide rails 221, the motor 222 drives a screw 223 to rotate to drive the lateral door panels 20b along the multiple The horizontal slide rail 221 is displaced. In practice, the vertical drive 21 and the horizontal drive 22 may also be a transmission configuration of a motor and gears, or may be a pneumatic cylinder.

Please refer to FIG. 5 , which illustrates that the third opening area 233 can be implemented in such a way that the two side door panels 20 b are in relative contact, thereby restricting the panel 30 from moving through the passage opening 12 . Furthermore, when the two lateral door panels 20b are in contact with each other, a door closing line 201 is formed, and the vertical door panels 20a can close the door closing line 201 in a staggered manner. In addition, the third opening area 233 can also be presented by the independent movement of the vertical door panel 20a in practice.
