DETAILED DESCRIPTION OF THE INVENTION

[0028] Various specific embodiments of the present application will be described below with reference to the accompanying drawings forming a part of this specification. Terms indicating directions such as "front", "rear", "upper", "lower", "left", and "right" are used in the present application to describe various exemplary structural components and elements of the present application. It should be understood that these terms are used in this specification merely for the convenience of illustration and are determined based on the exemplary directions shown in the accompanying drawings. Since the examples disclosed in the present application can be arranged in different directions, these terms indicating directions are for illustrative purposes only and should not be regarded as limiting.

[0029] FIG. 1A is a perspective view of a reflow oven at the time of closing according to an example of the present application, and FIG. 1B is a perspective view of the reflow oven of FIG. 1A at the time of opening. As shown in FIG. 1A, the reflow oven 100 includes a bracket 115 and a reflow oven chamber body 116, and the reflow oven chamber body 116 is supported by the bracket 115. The reflow oven chamber body 116 has an overall rectangular shape and has a length direction L, a height direction H, and a width direction W. The reflow oven chamber body 116 includes an upper chamber housing 101 and a lower chamber housing 102. The upper chamber housing 101 is positioned above the lower chamber housing 102 and is arranged opposite to each other to form a chamber accommodation space 153 together. The upper chamber housing 101 and the lower chamber housing 102 together form the chamber accommodation space 153. The chamber accommodation space 153 is used to accommodate a printed circuit board (PCB) to be soldered and a transmission device for transporting and transferring the printed circuit board (PCB). Here, in the width direction W of the reflow oven chamber body 116, the upper chamber housing 101 has opposing first side surfaces 121 and second side surfaces 122, and the first side surface 121 is rotatably connected to the lower chamber housing 102. When cleaning, maintenance, etc. are required for the reflow oven, the second side surface 122 can be pushed upward to open the upper chamber housing 101 from above the lower chamber housing 102.

[0030] As shown in FIG. 1B, the upper furnace chamber housing 101 and the lower furnace chamber housing 102 can be movably connected, the bracket 115 and the lower furnace chamber housing 102 are fixedly connected, and three support assemblies 111, 112, and 113 are provided between the bracket 115 and the upper furnace chamber housing 101. The three support assemblies 111, 112, and 113 each have one end connected to the upper furnace chamber housing 101, and the other end of each of the support assemblies 111, 112, and 113 is connected to the bracket 115. The bracket 115 and the lower furnace chamber housing 102 are fixedly connected, whereby the other end of each of the support assemblies 111, 112, and 113 is connected to the lower furnace chamber housing 102 via the bracket 115. That is, the three support assemblies 111, 112, and 113 are respectively connected to the upper furnace chamber housing 101 and the lower furnace chamber housing 102. The three support assemblies 111, 112, and 113 are used to provide support between the upper furnace chamber housing 101 and the lower furnace chamber housing 102.

[0031] The three support assemblies 111, 112, and 113 are connected to the first side surface 121 of the upper furnace chamber housing 101. When the upper furnace chamber housing 101 is opened, the three support assemblies 111, 112, and 113 can support the upper furnace chamber housing 101 and keep it open. The three support assemblies 111, 112, and 113 are arranged along the longitudinal direction of the reflow furnace. The support assemblies 111 and 113 are respectively close to both ends in the longitudinal direction of the reflow furnace and are side support assemblies. The support assembly 112 is positioned at the center in the longitudinal direction of the reflow furnace and is an intermediate support assembly.

[0032] FIG. 2A is a schematic diagram of the reflow furnace according to the present application in a low-temperature state, and FIG. 2B is a schematic diagram of the reflow furnace according to the present application in a high-temperature state.

[0033] The reflow oven is at a higher temperature during operation, i.e., in a high-temperature state. The reflow oven is at the same temperature as the ambient temperature during non-operation, i.e., in a low-temperature state. Due to the principle of thermal expansion, the shapes of the upper furnace chamber housing 101 and the lower furnace chamber housing 102 are different between the low-temperature state and the high-temperature state. So that it is ensured that the reflow oven is sealed in the high-temperature state, the reflow oven is designed to have a certain amount of deformation secured with respect to the shape of the upper furnace chamber housing 101 of the reflow oven when in the low-temperature state, whereby the reflow oven reaches an optimal shape when in the high-temperature state. Specifically, as shown in FIG. 2A, the upper furnace chamber housing 101 is an arc that is slightly bent upward in the longitudinal direction when in the low-temperature state, and the center of the upper furnace chamber housing 101 is slightly higher than both ends. As shown in FIG. 2B, the upper furnace chamber housing 101 in the high-temperature state is generally horizontal in the longitudinal direction, and the height of each part of the upper furnace chamber housing 101 is generally the same.

[0034] When the reflow oven is closed, the upper furnace chamber housing 101 is press-fitted into the lower furnace chamber housing 102 by its own weight, and the support assemblies 111, 112, and 113 do not support the upper furnace chamber housing 101. When the upper furnace chamber housing 101 is opened, the support assemblies 111, 112, and 113 support the upper furnace chamber housing 101. The reflow oven opens the upper furnace chamber housing 101 only for repair when it is in a low-temperature state. The height of the central upper furnace chamber housing 101 in the low-temperature state is greater than the height of both ends. Therefore, the total length of the intermediate support assembly 112 needs to be slightly longer than the lengths of the side support assemblies 111 and 113 so that the support assemblies 111, 112, and 113 can evenly support the upper furnace chamber housing. During the processing of the upper furnace chamber housing 101, the amount of bending of the upper furnace chamber housing 101 cannot be accurately controlled according to the process conditions. When installing the support assemblies 111, 112, and 113, it is necessary to adjust the length of one or more of the support assemblies 111, 112, and 113 to match the amount of bending of the upper furnace chamber housing 101, so that the support assemblies are evenly stressed when supporting the upper furnace chamber housing 101. In one example of the present application, the intermediate support assembly 112 is arranged as a support assembly with adjustable length. In another example of the present application, all of the support assemblies, or the side support assemblies as well, can be arranged as support assemblies with adjustable length.

[0035] Figure 3A is a perspective view of the support assembly of Figure 1B, and Figure 3B is an exploded view of the support assembly of Figure 3A. Figures 3A and 3B show the structure of the intermediate support assembly 112 of Figure 1B. As shown in Figures 3A and 3B, the support assembly 112 includes a fixture 301, a support rod 302, and an adjustment device 303. The fixture 301 is connected to the upper furnace chamber housing 101, and one end of the support rod 302 is connected to the lower furnace chamber housing 102. The adjustment device 303 is disposed between the support rod 302 and the fixture 301. The adjustment device 303 is movably connectable to the support rod 302 via a first support rod shaft 329 and is movable within a certain range with respect to the support rod 302. The adjustment device 303 includes an adjustment block 311 and a fastener 312, and the adjustment block 311 is fixedly connected to the fastener 312 and the fixture 301. The relative position between the adjustment block 311 and the fixture 301 is adjustable within a certain range before the fixed connection via the fastener 312. In one example of the present application, the support rod 302 is removably connected to the lower furnace chamber housing 102 so that the support rod can be easily replaced.

[0036] Figure 4 is a perspective view of the support rod 302 in the present application showing the structure of the support rod. As shown in Figure 4, the support rod 302 includes a first rod 401, a second rod 402, and a length adjustment mechanism 403. The second rod 402 has a first end 411 and a second end 412. The first rod 401 is sleeved within the second rod 402 and extends from the first end 411. The first rod 401 is movable relative to the second rod 402 along the axial direction of the support rod 302, changing the length of the support rod 302. The length adjustment mechanism 403 is provided at the second end 412 of the second rod 402, and the length adjustment mechanism 403 is connected to the control system of the reflow furnace and can receive signals from the control system, thereby driving the movement of the first rod 401 relative to the second rod 402 so that the support rod 302 reaches a predetermined length. In one example of the present application, the support rod 302 is a screw assembly. The second end 412 of the second rod 402 forms the first end of the support rod 302, and the distal end of the first rod 401 forms the second end of the support rod 302.

[0037] The distal end of the first rod 401 has a first support rod shaft attachment portion 450, and the first support rod shaft attachment portion 450 has a through hole 451 for attaching a first support rod shaft 329 that traverses the first rod 401 along the radial direction of the support rod. The first rod 401 is connected to the adjustment device 303 via the first support rod shaft 329. The first rod 401 and the first support rod shaft 329 are fixedly connected, whereby the first support rod shaft 329 is movable together with the first rod 401. In another example of the present application, the first support rod shaft attachment portion 450 can also be arranged on the support rod 302, and the first support rod shaft 329 is fixedly connected to the adjustment device 303.

[0038] Similarly, the second end 412 of the second rod 402 has a second support rod shaft attachment portion 460, and the second support rod shaft attachment portion 460 has a through hole 461 that traverses the second rod 402 along the radial direction of the support rod. The second rod 402 is connected to the bracket 115 via the second support rod shaft, and the second rod 402 is rotatable relative to the bracket 115 at an angle.

[0039] FIG. 5 is a perspective view of the adjustment block of FIG. 1B. As shown in FIG. 5, the adjustment block 311 includes a body portion 501 and a pair of ear portions 521 and 522. The body portion 501 is generally cubic and has a top surface 531 and a bottom surface 532 disposed opposite to each other, and a left side surface 533 and a right side surface 534 disposed opposite to each other. For ease of explanation, the direction perpendicular to the left side surface 533 is referred to as the first direction E1 of the adjustment block 311, and the direction perpendicular to the top surface 531 is referred to as the second direction E2 of the adjustment block 311. The left side surface 533 and the right side surface 534 each have four attachment holes 556 for receiving the fasteners 312. In one example of the present application, the attachment holes 556 are threaded holes and the fasteners 312 are screws.

[0040] The pair of ear portions 521 and 522 extend downward from the bottom surface 532 of the main body portion 501 along the second direction. Each of the ear portions 521 and 522 is generally a plate. There is a space between the ear portion 521 and the ear portion 522 that can accommodate the first support rod shaft attachment portion 450. The shaft attachment holes 504 and 505 are provided in the ear portion 521 and the ear portion 522, respectively. The shaft attachment holes 504 and 505 are formed as U-shaped holes. The width of the shaft attachment holes 504 and 505 in the first direction is smaller than the length in the second direction, and the width of the shaft attachment holes 504 and 505 in the first direction is equal to or slightly larger than the outer diameter of the first support rod shaft 329, whereby the first support rod shaft 329 can enter the shaft attachment holes 504 and 505 and move a certain distance along the second direction. The length of the shaft attachment holes 504 and 505 in the second direction is arranged to be larger than the dimension range in which the corresponding position of the upper furnace chamber housing is deformable.

[0041] FIG. 6A is a perspective view of the fixture in the present application, and FIG. 6B is a perspective view of the fixture in FIG. 6A from another angle. As shown in FIGS. 6A and 6B, the fixture 301 includes a housing connection portion 601 and an adjustment device connection portion 602. The housing connection portion 601 includes a rod portion 641 and an extension portion 642. The rod portion 641 is generally in the shape of a long strip, having a first end portion 651 and a second end portion 652. The first end portion 651 is connected to the adjustment device connection portion 602, and the second end portion 652 is connected to the extension portion 642. Here, the rod portion 641 is arranged along the width direction of the reflow furnace 100 and is connected to the top of the upper furnace chamber housing. The extension portion 642 extends from the second end portion 652 of the rod portion 641, and the extension portion 642 is connected to the first side surface 121 of the upper furnace chamber housing 101. The opening angle between the extension portion 642 and the rod portion 641 is configured to match the shape of the upper furnace chamber housing 101. The adjustment device connection portion 602 is adjacent to the second side surface 122 of the upper furnace chamber housing 101.

[0042] The adjustment device connection part 602 includes a pair of side walls 608 and 609 arranged opposite to each other. The pair of side walls 608 and 609 are arranged along the longitudinal direction of the reflow furnace 100, and there is an interval between the side wall 608 and the side wall 609 that can accommodate the adjustment block 311. Each of the side walls 608 and 609 is provided with four slots 616 that cross each side wall. The slots 616 are long and rod-shaped and extend generally along the height direction of the reflow furnace. The slots 616 form an adjustment portion 611. The fastener 312 of the adjustment device 303 can penetrate through the adjustment portion 611 and can move within the adjustment portion 611 along the extending direction of the rod-shaped slot 616. The fastener 312 can move within the adjustment portion 611 to adjust the position of the adjustment block 311 with respect to the adjustment device connection part 602. In another example of the present application, the adjustment portion 611 is arranged on the adjustment device 303. The adjustment portion 611 is a rod-shaped recess formed from a recess extending from the outer surface of the adjustment block 311 inward, and the fastener 312 can move within the recess.

[0043] The support assembly further includes an adjustment block support seat portion 620 arranged between the pair of side walls 608 and 609. The adjustment block support seat portion 620 is positioned above the adjustment block 311 along the height direction of the reflow furnace. The adjustment block support seat portion 620 includes a substrate 622 and support columns 623. Both ends of the substrate 622 are respectively connected to the pair of side walls 608 and 609. The support columns 623 can penetrate through the substrate 622 and are adjustable with respect to the substrate 622. The support columns 623 can adjust the length of the portion of the substrate 622 extended to abut against the adjustment block 311. In one example of the present application, the support columns 623 are screws, and screw holes that fit with the screws are provided on the substrate 622.

[0044] FIG. 7A is a side view of the support assembly of FIG. 3A when the upper furnace chamber housing is closed, and FIG. 7B is a side view of the support assembly of FIG. 3A when the upper furnace chamber housing is opened.

[0045] As shown in FIGS. 3A, 3B, 7A, and 7B, the adjustment device 303 in the present application is arranged to be adjustable with respect to the fixture 301, and the adjustment device 303 can be connected to different positions of the fixture 301. That is, before the adjustment device 303 is fastened and connected to the fixture 301, the adjustment device 303 is movable with respect to the fixture 301, and after the adjustment device 303 is fastened and connected to the fixture 301, the adjustment device 303 maintains each position with respect to the fixture 301.

[0046] When the support assembly 112 is attached to the reflow oven, it is necessary to adjust the relative position between the adjustment block 311 and the adjustment device connection part 602 according to the deformation amount of the upper furnace chamber housing 101. First, insert the fastener 312 into the mounting hole 556 of the adjustment block 311 through the slot 616. The fastener 312 is slidable within the slot 616. Then, adjust the adjustment block 311 to an appropriate position, rotate the fastener 312 to tighten the adjustment block 311, whereby the adjustment block 311 cannot move relative to the adjustment device connection part 602. In one example of the present application, the fastener 312 is positioned at a position close to the lower side of the slot 616.

[0047] In connection with FIGS. 3A, 6A, 7A, and 7B, the support column 623 is configured to abut against the top surface 531 of the adjustment block 311, further preventing the adjustment block 311 from moving upward due to the pressure of the support rod 302. The adjustment device 303 is fixed in a specific position by the fastener 312 and the support column 623 and cannot move relative to the adjustment device connection part 602. In the present application, the adjustment device 303 is used to correspond to different deformation amounts of each upper furnace chamber housing 101, so that no further adjustment is required after assembly as long as there is no relative position change. In one example of the present application, the adjustment device 303 is adjustable within a range of -5 mm to 12 mm.

[0048] The first support rod shaft 329 is positioned within the shaft mounting hole 505 and is movable and rotatable within the shaft mounting hole 505. When the upper furnace chamber housing is opened, the first support rod shaft 329 abuts against the top of the shaft mounting hole 505, and the support rod 302 provides support for the upper furnace chamber housing 101. In the high-temperature state when the upper furnace chamber housing 101 is closed, the upper furnace chamber housing 101 undergoes thermal deformation, where the central portion becomes flush or nearly flush with the end portions. The upper furnace chamber housing 101 is press-fitted into the lower furnace chamber housing 102 by its own weight, forming a seal with the lower furnace chamber housing 102, and the support rod 302 no longer provides support for the upper furnace chamber housing 101. At this point, the first support rod shaft 329 moves downward out of the top of the shaft mounting hole 505 to a position positioned at the center or bottom of the shaft mounting hole 505. The shaft mounting hole 505 is arranged such that the first support rod shaft 329 can move within the shaft mounting hole 505, whereby the support rod 302 can support the upper furnace chamber housing 101 when the upper furnace chamber housing 101 is opened and can be in a free state when the upper furnace chamber housing 101 is closed and no longer supports the upper furnace chamber housing 101. The free state of the support rod 302 means that there is no axial interaction between the support rod 302 and the adjusting device 303. That is, the support rod 302 is not providing support.

[0049] The end portions of the support rod 302 are rotatably connected to the upper furnace chamber housing 101 and the bracket 115 by shafts respectively, and the angle of the support rod 302 with respect to the upper furnace chamber housing 101 and the bracket 115 is variable.

[0050] FIG. 8A is a side view of the reflow furnace of FIG. 1B, and FIG. 8B is a cross-sectional view of the reflow furnace of FIG. 8A. In the figures, part (a) corresponds to the A-A cross-sectional line, part (b) corresponds to the B-B cross-sectional line, and part (c) corresponds to the C-C cross-sectional line. The A-A cross-sectional line, B-B cross-sectional line, and C-C cross-sectional line correspond to the support assemblies 111, 112, and 113 respectively.

[0051] In the present application, the specifications for the support rods 811, 302, and 813 for each of the support assemblies 111, 112, and 113 are the same. Each support rod has a length adjustment mechanism connected to the control system. The control system sends a signal to the adjustment mechanism, thereby moving the three support rods synchronously. As shown in FIG. 8B, when opened, the support rods 811, 302, and 813 have the same length. The centers of the first support rod shafts of the support rods 811, 302, and 813 are on the same horizontal line L1, and the centers of the second support rod shafts are on one horizontal line L2. The support rods 811, 302, and 813 have the same inclination angle with respect to the bracket 115, whereby the upper furnace chamber housing 101 is uniformly stressed in the width direction. In the present application, by using the same support rods 811, 302, and 813, it becomes easy to control the synchronous movement of the three support rods, and it is ensured that the rods have the same inclination angle with respect to the bracket 115. Therefore, it is desirable to arrange one or more of the support assemblies 111, 112, and 113 so that their lengths can be adjusted to accommodate the deformation ensured by the upper furnace chamber housing 101. In one example of the present application, the length of the intermediate support assembly 112 is adjustable, and the lengths of the side support assemblies 111 and 113 are not adjustable. In another example of the present application, the lengths of the side support assemblies 111 and 113 are adjustable, and the length of the intermediate support assembly 112 is not adjustable.

[0052] Referring to FIGS. 7A, 7B, and 8, in the present application, the relative positions of the adjustment device connection portions 602 of the respective adjustment blocks 311 of the support assemblies 111, 112, and 113 are different. Therefore, when the upper furnace chamber housing 101 is closed, the relative positions of the first support rod shafts 329 in the shaft mounting holes 505 are different. However, the respective support rods of the support assemblies 111, 112, and 113 are in a free state and no longer support the upper furnace chamber housing.

[0053] In another example of the present application, each support rod of the support assemblies 111, 112, and 113 can also be connected to the upper furnace chamber housing, and the fixture is connected to the lower furnace chamber housing.

[0054] The length-adjustable support assembly in the present application can accommodate the amount of bending ensured by the upper furnace chamber housing against deformations that may occur in a high-temperature state, so that the upper furnace chamber housing is uniformly supported when the upper furnace chamber housing is opened. In particular, in some longer reflow furnaces, the service life of the support assembly can be extended by uniformly supporting the upper furnace chamber housing. In one example of the present application, the length of the reflow furnace is 5 m or more.
