[0024] Various specific embodiments of the present application will be described below with reference to the accompanying drawings which constitute a part of this specification. It should be understood that in the following drawings, the same parts use the same figure numbers.

[0025] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "upper", "lower", "left", "right", "inner", "outer", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of description, and these terms are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations.

[0026] Figure 1A is a three-dimensional diagram of the reflow oven of the present application. Figure 1A As shown, the reflow oven includes a conveyor 101, a rack 102 and a heating device 103. The rack 102 is used to support the conveyor 101 and the heating device 103. The rack 102 has a length direction. The heating device 103 includes a plurality of upper heating units 105 and a plurality of lower heating units 107. The plurality of upper heating units 105 and the plurality of lower heating units 107 are arranged along the length direction of the rack 102, respectively, so as to form a conveying direction. The plurality of upper heating units 105 are arranged above the plurality of lower heating units 107, and are arranged at a certain distance from the plurality of lower heating units 107 in the height direction, so as to form a conveying space 104 having a conveying direction. The conveyor 101 includes a conveyor belt 106. The conveyor belt 106 can move along the conveying direction relative to the heating device 103, and is configured such that when the conveyor belt 106 is located in the conveying space 104, the conveyor belt 106 can carry and transport items. As an embodiment, the conveyor belt 106 can transport items to be heated (e.g., PCB boards). The object to be heated is placed on the conveyor belt 106. As the conveyor belt 106 moves along the conveying direction relative to the heating device 103, the object to be heated enters the conveying space 104. In the conveying space 104, the object to be heated passes through a plurality of upper heating units 105 and a plurality of lower heating units 107, which heat the object to be heated.

[0027] Figure 1B yes Figure 1A A perspective view of the conveyor 101 and the rack 102 is shown. Figure 1C yes Figure 1A The front view of the conveyor 101 and the rack 102 is shown. Figure 1B-1CAs shown, the frame 102 includes a support seat 122, a base 124 and several support columns 126. The support seat 122 is roughly plate-shaped and extends in the front-to-back direction to form a conveying direction with a certain length. The base 124 is roughly a rectangular frame. It is arranged below the support seat 122. Several support columns 126 are arranged between the support seat 122 and the base 124, and are arranged on the left and right sides along the conveying direction, so that the support seat 122 and the base 124 are connected and spaced a certain distance in the height direction to form a accommodating space 128. The conveyor belt 106 is annular and is arranged around the support seat 122. The conveying device 101 has a first closed-loop path. The conveyor belt 106 circulates in the first closed-loop path. Among them, some parts of the conveyor belt 106 are located in the conveying space 104 and are arranged along the conveying direction. Some parts of the conveyor belt 106 are located in the accommodating space 128. In other words, the conveyor belt 106 can reciprocate around the support base 122 relative to the rack 102, so as to transfer the articles carried on the conveyor belt 106 from a first end (e.g., the front end) of the rack 102 along a transfer direction to a second end (e.g., the rear end) of the rack 102 opposite to the first end. In the present application, the conveyor belt 106 moves at a first speed.

[0028] like Figure 1B-1C As shown, the conveyor also includes a support belt 108. The frame 102 can support the support belt 108. The support belt 108 is used to support the conveyor belt 106. Specifically, the support belt 108 is also annular and is arranged around the support seat 122. The conveyor has a second closed-loop path independent of the first closed-loop path. The support belt 108 circulates in the second closed-loop path. Among them, some parts of the support belt 108 are located in the conveying space 104 and arranged along the conveying direction. Some parts of the support belt 108 are located in the accommodating space 128. In other words, the support belt 108 can also move around the support seat 122 relative to the frame 102 in a cycle, and when the conveyor belt 106 and the support belt 108 are located in the conveying space 104, the second closed-loop path is located below the first closed-loop path. As a result, the first closed-loop path and the second closed-loop path do not completely overlap. In the conveying space 104, the support belt 108 supports the conveyor belt 106. In the present application, the support belt 108 moves at a first speed. The conveyor belt 106 and the support belt 108 are relatively stationary in the conveying space 104 .

[0029] like Figure 1B-1C As shown, the conveyor further includes a conveyor belt driving assembly 112 and a support belt driving component 114. The conveyor belt driving assembly 112 and the support belt driving component 114 are movably arranged on the frame 102. The conveyor belt driving assembly 112 is configured to drive the conveyor belt 106 to move relative to the frame 102. The support belt driving component 114 is configured to drive the support belt 108 to move relative to the frame 102.

[0030] Figure 2 Yes Figure 1B-1C A perspective view of one embodiment of the support belt 108 and the support belt drive component 114 is shown. Figure 2 As shown, the support belt 108 includes a plurality of links 201, a plurality of cover plates 202, a plurality of first shafts 211 and a plurality of second shafts 212. The plurality of links 201 are arranged in sequence along the second closed loop path. Each of the plurality of cover plates 202 is covered on two adjacent links 201. The plurality of cover plates 202 are rotatably connected to the two adjacent links 201 through the first shaft 211 and the second shaft 212. The cover plates 202 define a support surface 203 for supporting the conveyor belt 106. Specifically, each link 201 includes a first cylinder 221, a second cylinder 222, a first side plate 231 and a second side plate 232. The central axis of the first cylinder 221 and the second cylinder 222 is transverse to the conveying direction (i.e., the central axis is extended in the left-right direction), and the central axis of the first cylinder 221 and the second cylinder 222 is arranged along the second closed loop path. That is, in the conveying space 104, the central axes of the first column 221 and the second column 222 are arranged along the conveying direction. The first side plate 231 and the second side plate 232 are respectively arranged on the left and right sides of the first column 221 and the second column 222, and are connected to the ends of the first column 221 and the second column 222. The first through hole 223 and the second through hole 224 penetrate the link 201 in the left-right direction, and are respectively coaxially arranged with the central axes of the first column 221 and the second column 222. The first through hole 223 and the second through hole 224 are used to receive the second shaft 212 and the first shaft 211, respectively.

[0031] like Figure 2 As shown, the cross section of the cover plate 202 is an upside-down "concave" shape. Specifically, the cover plate 202 includes a cover top plate 240, a first cover side plate 241 and a second cover side plate 242. The first cover side plate 241 and the second cover side plate 242 extend downward from opposite sides (e.g., the left side and the right side) of the cover top plate 240. The distance between the first cover side plate 241 and the second cover side plate 242 is greater than the distance between the first side plate 231 and the second side plate 232, so that the first cover side plate 241 and the second cover side plate 242 can be arranged on the outside of the first side plate 231 and the second side plate 232. The upper surface of the cover top plate 240 is a support surface 203. The support surface 203 is substantially a plane. Each of the first cover side plate 241 and the second cover side plate 242 is provided with a first connecting hole 243 and a second connecting hole 244 , which are respectively arranged to correspond to the first through hole 223 of the first column 221 and the second through hole 224 of the second column 222 for receiving the second shaft 212 and the first shaft 211 .

[0032] refer to Figure 2As shown, the process of connecting two adjacent links 201 with one cover plate 202 is as follows: a portion of the cover plate 202 is covered on the link 201 located at the front side of the two adjacent links 201, so that the first connection hole 243 of the cover plate 202 is aligned with the second through hole 224 of the second column 222 on the link 201 located at the front side of the two links 201. The first shaft 211 is inserted into the first connection hole 243 and the second through hole 224, so that the cover plate 202 is rotatably connected to the link 201 located at the front side of the two links 201. Another portion of the cover plate 202 is covered on the link 201 located at the rear side of the two adjacent links 201, so that the second connection hole 244 of the cover plate 202 is aligned with the first through hole 223 of the first column 221 on the link 201 located at the rear side of the two links 201. The second shaft 212 is inserted into the second connection hole 244 and the first through hole 223 , so that the cover plate 202 is rotatably connected to the link 201 located at the rear side of the two links 201 .

[0033] After the plurality of chain links 201 and the plurality of cover plates 202 are connected in sequence, the annular support belt 108 is assembled. After the support belt 108 is assembled, the upper surfaces of the cover plates 240 of the plurality of cover plates 202 can be arranged substantially continuously, so that when the support belt 108 is located in the conveying space 104, the upper surface of the support belt 108 can form a substantially continuous and substantially planar support surface 203 for supporting the conveyor belt 106.

[0034] like Figure 2 As shown, in the present application, the support belt driving component 114 is a support belt sprocket 251. The support belt sprocket 251 can cooperate with the above-mentioned plurality of chain links 201, thereby driving the support belt 108 to move. Specifically, the support belt sprocket 251 is rotatably arranged on the frame 102. The support belt sprocket 251 has a plurality of sprocket teeth 252, which are used to engage with the first shaft 211 and the second shaft 212 of the above-mentioned chain link 201. The rotation of the support belt sprocket 251 can drive the support belt 108 to rotate in the second closed loop path.

[0035] Figure 3 Yes Figure 1B-1C A perspective view of an embodiment of the conveyor belt 106 and the conveyor belt driving assembly 112 is shown. Figure 3As shown, the conveyor belt driving assembly 112 includes a first chain 301, a second chain 302, a first conveyor belt sprocket 311, and a second conveyor belt sprocket 312. The first conveyor belt sprocket 311 can cooperate with the first chain 301, thereby driving the first chain 301 to move. The second conveyor belt sprocket 312 can cooperate with the second chain 302, thereby driving the second chain 302 to move. The first chain 301 and the second chain 302 are respectively annular, which are respectively arranged on opposite sides of the conveyor belt 106 (for example, the left side and the right side), and are connected to the conveyor belt 106, so that when the first chain 301 and the second chain 302 move, the conveyor belt 106 can be driven to move. In the present application, the structure of the first conveyor belt sprocket 311 and the second conveyor belt sprocket 312 is the same as Figure 2 The supporting belt sprocket 251 described above has the same structure and will not be described in detail here. Figure 4 Make an introduction.

[0036] like Figure 3 As shown, the conveyor belt 106 of the present application includes several long rods 322 and several iron wires 324. The central axis of the long rod 322 is transverse to the conveying direction (that is, the central axis is extended in the left-right direction), and the central axes of the several long rods 322 are arranged along the first closed-loop path. In other words, in the conveying space 104, the central axes of the several long rods 322 are arranged along the conveying direction. Several iron wires 324 are wound around the several long rods 322, so that the several long rods 322 and the several iron wires 324 can form a substantially continuous surface. When the conveyor belt 106 is located in the conveying space 104, the several long rods 322 and the several iron wires 324 roughly form a plane, thereby carrying items.

[0037] The first chain 301 and the second chain 302 have the same structure. Figure 4 , take the first chain 301 as an example to introduce:

[0038] Figure 4 3 is a partial exploded view of the first chain 301. Figure 4 As shown, the first chain 301 includes a plurality of chain links 201 and a plurality of connecting links 401. The plurality of chain links 201 are arranged along a first closed loop path. The plurality of connecting links 401 are rotatably connected to two adjacent chain links 201. The structure of the chain links 201 in the first chain 301 is similar to Figure 2The structures of the chain links 201 described are the same and will not be described here. Specifically, each connection link 401 includes a first plate 411, a second plate 412, a first column 421 and a second column 422. The length of the first column 421 and the second column 422 is greater than the length of the chain link 201, so that when the connection link 401 connects two adjacent chain links 201, the first plate 411 and the second plate 412 are respectively located on the outside of the chain link 201. The first plate 411 is arranged on the right side of the first column 421 and the second column 422, and is connected to the first column 421 and the second column 422. The central axes of the first column 421 and the second column 422 are transverse to the transmission direction, and the central axes of the first column 421 and the second column 422 are arranged along the first closed loop path. The second plate 412 is provided with a first connection hole 431 and a second connection hole 432, which are respectively arranged corresponding to the first column 421 and the second column 422.

[0039] refer to Figure 4 As shown, the process of connecting two adjacent links 201 with one connecting link 401 is as follows: the left end of the first column 421 is inserted into the second through hole 224 of the second column 222 on the link 201 located on the front side of the two links 201. The left end of the second column 422 is inserted into the first through hole 223 of the first column 221 on the link 201 located on the rear side of the two links 201. Then, the first column 421 and the second column 422 are respectively inserted into the first connecting hole 431 and the second connecting hole 432 provided on the second plate 412. As an example, the first column 421 and the second column 422 can be interference-fitted with the first connecting hole 431 and the second connecting hole 432, so that the second plate 412, the first column 421 and the second column 422 are connected. As another example, after the first column 421 and the second column 422 are respectively inserted into the first connection hole 431 and the second connection hole 432 provided on the second plate 412, the second plate 412, the first column 421 and the second column 422 are connected by welding. After several chain links 201 and several connecting links 401 are connected in sequence, the annular first chain 301 and the second chain 302 are assembled.

[0040] Figure 5 5 is a side view of the driving system of the conveyor of the present application. The conveyor includes a driving device 502. The driving device 502 is configured to drive the conveyor belt drive assembly 112 and the support belt drive component 114 to move. Specifically, the driving device 502 is configured to drive the support belt sprocket 251, the first conveyor belt sprocket 311 and the second conveyor belt sprocket 312 to rotate.

[0041] like Figure 5As shown, the conveying device also includes a first sprocket 522, a second sprocket 524 and a third sprocket 526. The first sprocket 522, the second sprocket 524 and the third sprocket 526 can all be matched with the conveyor belt 106. The conveyor belt 106 is arranged around the conveyor belt sprocket (that is, the first conveyor belt sprocket 311 and the second conveyor belt sprocket 312), the first sprocket 522, the second sprocket 524 and the third sprocket 526, so as to circulate in the first closed-loop path. The conveying device also includes a fourth sprocket 512, a fifth sprocket 514 and a sixth sprocket 516. The fourth sprocket 512, the fifth sprocket 514 and the sixth sprocket 516 can all be matched with the support belt 108. The support belt 108 is arranged around the support belt sprocket 251, the fourth sprocket 512, the fifth sprocket 514 and the sixth sprocket 516, so as to circulate in the second closed-loop path. In the conveying space 104, the support belt 108 is located below the conveying belt 106, thereby supporting the conveying belt 106. Therefore, the first closed loop path and the second closed loop path do not completely overlap.

[0042] like Figure 5 As shown, the conveying device also includes a drive chain 506. The drive chain 506 is sleeved on the output end 504 of the driving device 502, the rotating shaft of the conveyor belt sprocket (i.e., the first conveyor belt sprocket 311 and the second conveyor belt sprocket 312) and the rotating shaft of the support belt sprocket 251, so that the driving device 502 can drive the conveyor belt sprocket and the support belt sprocket 251 to rotate through the drive chain 506. In one embodiment, the driving device 502 is a motor. The output end 504 of the driving device 502 is a rotating sprocket. The conveyor belt sprocket (i.e., the first conveyor belt sprocket 311 and the second conveyor belt sprocket 312) and the support belt sprocket 251 are driven to rotate by a driving device 502, thereby driving the conveyor belt 106 and the support belt 108 to move.

[0043] In addition, in the present application, the radius of the conveyor belt sprocket (i.e., the first conveyor belt sprocket 311 and the second conveyor belt sprocket 312) is the same as the radius of the support belt sprocket 251. Since the driving chain 506 drives the rotating shaft of the conveyor belt sprocket and the rotating shaft of the support belt sprocket 251 to rotate at the same speed (i.e., the angular velocity of the conveyor belt sprocket and the support belt sprocket 251), the movement speed of the conveyor belt 106 and the support belt 108 (i.e., the linear velocity of the conveyor belt sprocket and the support belt sprocket 251) is the same. As a result, the conveyor belt 106 and the support belt 108 move at the same speed to be relatively stationary in the conveying space 104.

[0044] It should be noted that, although the conveyor belt 106 and the support belt 108 are driven to rotate by a driving device 502 in the present application, in other embodiments, the conveyor belt 106 and the support belt 108 may be driven to rotate by different driving devices respectively, as long as the conveyor belt 106 and the support belt 108 can be kept relatively still in the conveying space 104.

[0045] In the prior art, the conveyor belt is severely worn and needs to be replaced frequently. The inventor of the present application found that the wear of the conveyor belt is caused by friction with the support belt. In addition, for the reflow oven, replacing the conveyor belt requires removing part of the heating device first. The operation steps are cumbersome.

[0046] The support belt 108 in the conveyor device of the present application can not only support the conveyor belt 106, but also because the support belt 108 and the conveyor belt 106 each have a power source to drive their movement (i.e., the support belt driving component 114 and the conveyor belt driving assembly 112), the support belt 108 and the conveyor belt 106 remain relatively stationary, thereby avoiding the wear of the conveyor belt 106 and the support belt 108 during movement. Therefore, the conveyor device of the present application can greatly reduce the replacement frequency of the conveyor belt 106. The conveyor device of the present application reduces the operating cost while reducing the operating cost of personnel.

[0047] In addition, when the conveyor belt 106 transports components of small size and light weight, the components are placed on a substrate (not shown), and the substrate is placed on the conveyor belt 106. Since the support belt 108 and the conveyor belt 106 remain relatively stationary, the conveyor belt 106 will not shake due to friction with the support belt 108, thereby reducing the offset of the components. In one example, a reflow oven is used to heat solder paste to fix the components on the PCB board. The relative position offset of the components and the PCB board is required to be within 25%. The conveying device of the present application can effectively reduce the relative position offset of the components and the PCB board.

[0048] It should also be noted that, although the conveying device in the present application is applied to a reflow oven, those skilled in the art will appreciate that the conveying device in the present application can be applied to scenarios where various items need to be transported.

[0049] Although the present disclosure has been described in conjunction with the examples of the embodiments summarized above, various alternatives, modifications, changes, improvements and / or substantially equivalent solutions, whether known or currently or foreseeable in the near future, may be apparent to those of ordinary skill in the art. In addition, the technical effects and / or technical problems described in this specification are exemplary rather than restrictive; so the disclosure in this specification may be used to solve other technical problems and have other technical effects and / or may solve other technical problems. Therefore, the examples of the embodiments of the present disclosure as stated above are intended to be illustrative rather than restrictive. Various changes may be made without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure is intended to include all known or earlier developed alternatives, modifications, changes, improvements and / or substantially equivalent solutions.
