Description

Background Technical field

[0001] The present disclosure relates to a reflow oven. In particular, the present disclosure relates to a reflow oven whose transfer device can move in three dimensions. State of the art

[0002] Due to the development of the electronics industry, welding technology is widespread, and the reflow oven, designed for soldering the joints of electronic components, is an application of this technology. The reflow soldering process reduces bubbles within the solder joints and thus increases the yield.

[0003] In conventional reflow ovens, the support rod used to reposition the electronic devices can only move along a Y-axis and a Z-axis. After the support rod has moved the tray to a specific location, it is necessary to move it back along the Y-axis to avoid interfering with the reflow process. Therefore, the support rod requires a significant amount of space along the Y-axis, resulting in wasted space.

[0004] Due to the problems mentioned above, it is a goal for experts in this field to effectively increase the space efficiency of reflow ovens. Brief summary of the invention

[0005] According to one aspect, the present disclosure provides a reflow oven comprising a transfer base, two support rod assemblies, an X-axis motion mechanism, a Z-axis motion mechanism, and a Y-axis motion mechanism. The two support rod assemblies are movably arranged on the transfer base to move a shell, and each of the support rod assemblies has a support rod and a roller gear located at one end of the support rod.The X-axis motion mechanism is connected to the two support rod assemblies and comprises an X-axis support frame, two X-axis slides movably mounted on the X-axis support frame and each connected to the two support rod assemblies, two X-axis drive gears each mounted on the two X-axis slides and engaging with the two roller gears, and two X-axis drive components designed to drive the two X-axis slides so that the two X-axis slides can move closer to or away from each other along an X-axis. The Z-axis motion mechanism includes a Z-axis slider connected to the X-axis support frame and a Z-axis drive component designed to drive the Z-axis slider to move up or down along a Z-axis.The Y-axis motion mechanism comprises a Y-axis slider connected to the X-axis support frame and a Y-axis drive component configured to drive the Y-axis slider to move along a Y-axis.

Detailed description

[0016] Fig. Figure 1 is a three-dimensional schematic view of a reflow oven 1000 according to an embodiment of the present disclosure. Fig. Figure 2 is a schematic partial view of the reflow oven 1000 according to the embodiment in Fig. 1. Fig. Figure 3 is a partially exploded view of the reflow oven 1000 according to the embodiment in Fig. 1. The reflow oven 1000 has a transfer base 1100, two support rod assemblies 1200, an X-axis motion mechanism 1300, a Z-axis motion mechanism 1400 (in Fig. 7 marked) and a Y-axis movement mechanism 1500 (in Fig. 7 marked) on.

[0017] The two support rod assemblies 1200 are movably arranged on the transfer base 1100 to support a shell T1 (in Fig. 8 shown) to relocate, and each of the support rod assemblies 1200 has a support rod 1201 and a roller gear 1202 which is arranged at one end of the support rod 1201. The X-axis motion mechanism 1300 is connected to the two support rod assemblies 1200 and comprises an X-axis support frame 1301, two X-axis slides 1302, which are movably arranged on the X-axis support frame 1301 and each connected to the two support rod assemblies 1200, two X-axis drive gears 1303, each arranged on the two X-axis slides 1302, and two X-axis drive components 1304, each configured to drive the two X-axis slides 1302 so that the two X-axis slides 1302 can move closer to or further apart from each other along an X-axis. The Z-axis motion mechanism 1400 comprises a Z-axis slide 1401 (in Fig. 7), which is connected to the X-axis support frame 1301, and a Z-axis drive component 1402 (in Fig. 4) which is configured to drive the Z-axis slider 1401 to move up or down along a Z-axis. The Y-axis motion mechanism 1500 has a Y-axis slider 1501 (in Fig. 7 marked), which is connected to the X-axis support frame 1301 (in Fig. 7) is connected, as well as a Y-axis drive component 1502, which is configured to drive the Y-axis slider 1501 along a Y-axis. The two X-axis drive components 1304 each drive the two X-axis sliders 1302 so that the two support rod assemblies 1200 can move closer to each other along the X-axis, and each of the X-axis drive gears 1303 drives each of the roller gears 1202 so that each of the support rod assemblies 1200 can rotate.When each of the support rod assemblies 1200 is in a closed position, the Z-axis drive component 1402 drives the Z-axis slider 1401 so that the associated X-axis support frame 1301 can move upwards along the Z-axis, allowing the support rod assemblies 1200 to come into contact with the shell T1, and the Y-axis drive component 1502 drives the Y-axis slider 1501 to move the X-axis support frame 1301 along the Y-axis to move the shell T1 from a first position to a second position.

[0018] Therefore, with the configuration in which the X-axis motion mechanism 1300, the Z-axis motion mechanism 1400, and the Y-axis motion mechanism 1500 are arranged on the transfer base 1100, the support rod assemblies 1200 can be moved three-dimensionally to increase space efficiency. Furthermore, by rotating each of the support rod assemblies 1200 around the X-axis, the structure is more stable.

[0019] More precisely, the transfer base 1100 can comprise a furnace body 1101 and a cover body 1102. The furnace body 1101 is rectangular and columnar, with a longitudinal direction parallel to the Y-axis, a lateral direction parallel to the X-axis, and a vertical direction parallel to the Z-axis. The cover body 1102 is also rectangular and columnar and can be pivotally mounted on one side of the furnace body 1101. The two support rod assemblies 1200 project along the Y-axis into an upper region within the furnace body 1101 and are spaced apart from each other along the X-axis. The length of each of the support rod assemblies 1200 is slightly greater than that of the furnace body 1101, thereby lifting the shell T1 and transferring it into different chambers within the furnace body 1101.

[0020] In the present embodiment, there are two X-axis motion mechanisms 1300. The two X-axis motion mechanisms 1300 are each arranged on opposite sides of the furnace body 1101. The two sides are parallel to the X-axis. Each of the X-axis support frames 1301 is essentially a rectangular plate. The two X-axis sliders 1302 are each movably arranged on opposite sides of one of the X-axis support frames 1301. Each of the X-axis drive components 1304 can be a motor and is arranged on a bottom side of each of the X-axis sliders 1302. Each of the X-axis drive components 1304 is moved with each of the X-axis sliders 1302. Each of the X-axis drive gears 1303 is arranged on a top side of each of the X-axis sliders 1302.Two ends of each support rod assembly 1200 extend into the top of each X-axis slider 1302, allowing each roller gear 1202 to engage with each X-axis drive gear 1303. One of the X-axis motion mechanisms 1300 is described in detail below.

[0021] The X-axis motion mechanism 1300 can further comprise two racks 1305 arranged on the X-axis support frame 1301, as well as two X-axis motion gears 1306, each arranged on the X-axis slides 1302 and each rotated by the X-axis drive components 1304. Each of the X-axis motion gears 1306 engages with each of the racks 1305. The X-axis motion mechanism 1300 can further comprise two X-axis drive rods 1307. One end of each of the X-axis drive rods 1307 is connected to each of the X-axis drive components 1304, and another end of each of the X-axis drive rods 1307 is designed such that each of the X-axis drive gear units 1303 can be mounted on it. Each of the X-axis motion gear units 1306 is mounted on each of the X-axis drive rods 1307.When each of the X-axis drive components 1304 rotates each of the X-axis drive rods 1307, each of the X-axis motion gears 1306 and each of the X-axis drive gears 1303 are driven to allow each of the support rods 1201 to move and rotate along the X-axis at the same time.

[0022] Each of the X-axis drive rods 1307 is arranged on the X-axis slide 1302, and the longitudinal direction of each of the X-axis drive rods 1307 is parallel to the Z-axis. The other end of each of the X-axis drive rods 1307 is connected to each of the X-axis drive gears 1303, and each of the X-axis drive gears 1303 is engaged with each of the roller gears 1202. Each of the roller gears 1202 and each of the X-axis drive gears 1303 is a bevel gear, thereby driving each of the X-axis drive rods 1307, whose longitudinal direction is parallel to the Z-axis, and each of the support rods 1201, whose longitudinal direction is parallel to the Y-axis.

[0023] Each of the X-axis motion gears 1306 is mounted at one end of each of the X-axis drive rods 1307 and engages with each of the racks 1305. The X-axis motion mechanism 1300 can further comprise two X-axis projection frames 1312, which are arranged on the X-axis support frame 1301. The two racks 1305 are each arranged on the two X-axis projection frames 1312, and one longitudinal direction of each of the racks 1305 is parallel to the X-axis. An inner groove (not shown) is arranged on one side of each of the X-axis projection frames 1312 facing the X-axis support frame 1301, with each of the X-axis sliders 1302 penetrating into each inner groove and being movable in each inner groove.Each of the X-axis motion gears 1306 is a spur gear gear, so that each of the X-axis sliders 1302 can be driven by each of the X-axis drive components 1304 to move along the X-axis via each of the X-axis motion gears 1306.

[0024] The X-axis motion mechanism 1300 can further comprise two X-axis cover bodies 1313. Each of the X-axis cover bodies 1313 is cover-shaped and arranged on the upper side of each of the X-axis slides 1302 to cover and protect each of the X-axis drive rods 1307, each of the X-axis drive gears 1303 and each of the roller gears 1202 arranged therein.

[0025] In the present embodiment, it should be noted that because each of the X-axis motion gears 1306 and each of the X-axis drive gears 1303 is arranged on each of the X-axis drive rods 1307, when each of the X-axis drive components 1304 rotates each of the X-axis drive rods 1307, each of the X-axis motion gears 1306 rotates relative to each of the racks 1305, and each of the X-axis drive rods 1307 rotates each of the roller gears 1202, allowing each of the support rods 1201 to move and rotate along the X-axis. In another embodiment, each of the X-axis motion gears and each of the X-axis drive gears can be driven by different components and can also each drive each of the support rods to move and rotate along the X-axis.

[0026] The X-axis motion mechanism 1300 can further comprise two rails 1308 and two sliding blocks 1309. The two rails 1308 are arranged on the X-axis support frame 1301. Each of the sliding blocks 1309 is connected to each of the X-axis sliders 1302. The shape of each of the sliding blocks 1309 corresponds to each of the rails 1308; therefore, each of the X-axis sliders 1302 can move along each of the rails 1308 over each of the sliding blocks 1309 when each of the X-axis motion gears 1306 is rotated relative to each of the racks 1305.

[0027] The X-axis motion mechanism 1300 can further comprise two flat connectors 1310 and two photointerrupters 1311. The two flat connectors 1310 are each arranged on the undersides of the X-axis sliders 1302. The two photointerrupters 1311 are arranged on the X-axis support frame 1301, specifically in the same plane of the X-axis support frame 1301 as each of the X-axis sliders 1302, and each of the flat connectors 1310 can slide along the X-axis with each of the X-axis sliders 1302. Each of the photointerrupters 1311 is arranged in a movement path of each of the flat connectors 1310, and the position of each of the photointerrupters 1311 can represent a limit position. If each flat connector 1310 triggers each of the photointerrupters 1311, each of the X-axis sliders 1302 moves to an endpoint, and each of the X-axis drive components 1304 can be stopped.

Fig. Figure 5 is an enlarged partial cross-sectional side view of the reflow oven 1000 according to the embodiment in Fig. 1. Fig. Figure 6 is another enlarged partial cross-sectional side view of the reflow oven 1000 according to the embodiment in Fig. 1. With reference to the Fig. 4, Fig. 5 to Fig. 6 and with reference to Fig. 1. The Z-axis motion mechanism 1400 can further comprise a Z-axis drive rod 1403, a Z-axis drive bevel gear 1404, a Z-axis screw bevel gear 1405, and a Z-axis screw 1406. One end of the Z-axis drive rod 1403 is arranged on the Z-axis drive component 1402. The Z-axis drive bevel gear 1404 is arranged on the other end of the Z-axis drive rod 1403. The Z-axis screw bevel gear 1405 engages with the Z-axis drive bevel gear 1404. The Z-axis screw 1406 is connected to the Z-axis slide 1401 (in Fig. (7 shown) is screwed together and connected to the Z-axis screw bevel gear 1405. When the Z-axis drive component 1402 rotates the Z-axis drive rod 1403, the Z-axis drive bevel gear 1404 drives the Z-axis screw bevel gear 1405 to drive the Z-axis screw 1406, which allows the Z-axis slider 1401 to move along the Z-axis.

[0029] In particular, the Z-axis drive component 1402 is a motor and is arranged below a central section of the furnace body 1101. The Z-axis motion mechanism 1400 can further comprise a first Z-axis drive bevel gear 1412 and a second Z-axis drive bevel gear 1413. The first Z-axis drive bevel gear 1412 is arranged on the Z-axis drive component 1402, the second Z-axis drive bevel gear 1413 is engaged with the first Z-axis drive bevel gear 1412, and the second Z-axis drive bevel gear 1413 is mounted on one end of the Z-axis drive rod 1403. One end of the Z-axis drive rod 1403 is parallel to the Y-axis, the other end of the Z-axis drive rod 1403 is connected to the Z-axis drive bevel gear 1404, the Z-axis drive bevel gear 1404 is engaged with the Z-axis screw bevel gear 1405, and the Z-axis screw bevel gear 1405 is connected to one end of the Z-axis screw 1406.Since the Z-axis drive bevel gear 1404 and the Z-axis screw bevel gear 1405 are bevel gears, the Z-axis drive rod 1403, whose longitudinal direction is parallel to the Y-axis, and the Z-axis screw 1406, whose longitudinal direction is parallel to the Z-axis, can be driven. The Z-axis screw 1406 extends upwards along the Z-axis and has an external thread. The Z-axis slide 1401 is a square plate. The Z-axis slide 1401 has a central hole in its middle, which has internal threads that correspond to the external thread of the Z-axis screw 1406, and thus the Z-axis screw 1406 is screwed to the Z-axis slide 1401.

[0030] Fig. Figure 7 is another schematic partial view of the reflow oven 1000 according to the embodiment in Fig. 1. With reference to Fig. 7 with references to the Fig. 3, Fig. 4, Fig. 5 to Fig. 6. The Z-axis motion mechanism 1400 can further comprise two Z-axis guide rods 1407 and a Z-axis connecting seat 1408. The Y-axis slider 1501 has two guide holes (not shown), and one direction of extension of each of the guide holes is parallel to the Z-axis. The two Z-axis guide rods 1407 are each guided through the two guide holes. The Z-axis connecting seat 1408 is connected to the two Z-axis guide rods 1407.

[0031] Each of the Z-axis guide rods 1407 is a circular column whose direction of extension is parallel to the Z-axis. Each of the guide holes is a circular hole whose direction of extension is parallel to the Z-axis, so that one end of each of the Z-axis guide rods 1407 can be movably inserted into each of the guide holes. The other end of each of the Z-axis guide rods 1407 can be connected to the Z-axis connecting seat 1408. The Z-axis connecting seat 1408 is a rectangular body, and each of the Z-axis guide rods 1407 is arranged below the Z-axis connecting seat 1408 at intervals along the X-axis.

[0032] The Z-axis motion mechanism 1400 can further comprise two Z-axis connecting rods 1416, which are arranged between the Y-axis slider 1501 and the X-axis support frame 1301, as well as two Z-axis guide blocks 1417, which are arranged on the Z-axis slider 1401 and are designed such that the two Z-axis connecting rods 1416 can pass through them.

[0033] The first ends of the Z-axis connecting rods 1416 are arranged at intervals along the Y-axis on two sides of the Z-axis connecting seat 1408. The Z-axis connecting rods 1416 extend along the Y-axis, and their second ends are each arranged on the X-axis support frame 1301. The two Z-axis guide blocks 1417 are arranged on two sides of the Z-axis slide 1401. Each of the Z-axis guide blocks 1417 has a hole in its center through which the Z-axis connecting rods 1416 pass, allowing each Z-axis guide block 1417 to move relative to each of the Z-axis connecting rods 1416.

[0034] The Z-axis drive component 1402 drives the second Z-axis drive bevel gear 1413 via the first Z-axis drive bevel gear 1412, thereby rotating the Z-axis drive rod 1403 and the Z-axis drive bevel gear 1404, and driving the Z-axis screw bevel gear 1405, the Z-axis screw 1406 and the Z-axis slide 1401, enabling the Z-axis slide 1401 to be raised or lowered along the Z-axis. In addition, each of the Z-axis guide blocks 1417 and each of the Z-axis connecting rods 1416 are raised or lowered, thereby driving the Z-axis connecting seat 1408 and each of the Z-axis guide rods 1407 to move the X-axis support frame 1301, thereby moving the two support rod assemblies 1200, which are arranged on the X-axis support frame 1301, along the Z-axis.

[0035] The Z-axis motion mechanism 1400 can further comprise a Z-axis horizontal lifting rod 1409. The Z-axis horizontal lifting rod 1409 is configured to support the two support rod assemblies 1200. The Z-axis drive component 1402 can be configured to drive the Z-axis horizontal lifting rod 1409 to move it along the Z-axis.

[0036] The Z-axis motion mechanism 1400 can further comprise two Z-axis lifting connecting rods 1410 and a Z-axis lifting platform 1411. The Z-axis lifting connecting rods 1410 are each arranged at two ends of the Z-axis horizontal lifting rod 1409. The Z-axis lifting platform 1411 can be configured such that the Z-axis lifting connecting rods 1410 can be arranged on it. The Z-axis drive component 1402 drives the Z-axis lifting platform 1411 to drive the two Z-axis lifting connecting rods 1410 and the Z-axis horizontal lifting rod 1409, thereby moving the two support rod assemblies 1200 along the Z-axis.

[0037] More precisely, the Z-axis motion mechanism 1400 can further comprise a third Z-axis drive bevel gear 1414 and a Z-axis helicopter 1415. The third Z-axis drive bevel gear 1414 engages with the second Z-axis drive bevel gear 1413 and is located at one end of the Z-axis helicopter 1415. The Z-axis helicopter 1415 extends upward along the Z-axis and has external threads. The Z-axis screw 1406 extends upward along the Z-axis and has external threads. The Z-axis lifting platform 1411 is a square plate. The Z-axis lifting platform 1411 has a central hole in the middle, the central hole has internal threads that correspond to the external threads of the Z-axis lifting screw 1415, and thus the Z-axis lifting screw 1415 is screwed to the Z-axis lifting platform 1411 and lifts the Z-axis lifting platform 1411.The extension direction of each of the two Z-axis lifting connecting rods 1410 is parallel to the Z-axis. First ends of the Z-axis lifting connecting rods 1410 are each arranged on two sides of the Z-axis lifting platform 1411 along the Y-axis, and second ends of the Z-axis lifting connecting rods 1410 are each arranged at two ends of the Z-axis horizontal lifting rod 1409.

[0038] The Z-axis horizontal lifting rod 1409 extends parallel to the X-axis. Middle sections of the two support rod assemblies 1200 are arranged at opposite ends of the Z-axis horizontal lifting rod 1409. The Z-axis horizontal lifting rod 1409 can not only be used to lift the two support rod assemblies 1200, but also to prevent bending of the middle sections of the two support rod assemblies 1200 caused by excessive length of the two support rod assemblies 1200.

[0039] The Z-axis drive component 1402 drives the first Z-axis drive bevel gear 1412 and the second Z-axis drive bevel gear 1413, which in turn drives the third Z-axis drive bevel gear 1414, which rotates the Z-axis helicopter 1415, allowing the Z-axis lift platform 1411, the two Z-axis lift connecting rods 1410 and Z-axis horizontal lift rod 1409 to be moved upwards, thereby pushing the two support rod assemblies 1200 along the Z-axis.

[0040] It should be noted that when the Z-axis drive component 1402 is actuated, the Z-axis horizontal lifting rod 1409 is driven, while the X-axis support frame 1301 is moved by means of the Z-axis slider 1401 and the support rod assemblies 1200 are raised or lowered at one end and in their middle section.

[0041] As in Fig. As shown in Figure 7, the Y-axis motion mechanism 1500 can further include a Y-axis screw 1503 which is arranged between the Y-axis drive component 1502 and the Y-axis slider 1501.

[0042] The Y-axis drive component 1502 can be a motor and is located below the furnace body 1101. One end of the Y-axis screw 1503 is connected to the Y-axis drive component 1502. The Y-axis screw 1503 extends along the Y-axis and has external threads. The Y-axis slide 1501 is a square plate. The Y-axis slide 1501 has a central hole in its center, which has internal threads that correspond to the external threads of the Y-axis screw 1503, thus screwing the Y-axis screw 1503 to the Y-axis slide 1501.

[0043] The Y-axis drive component 1502 rotates the Y-axis screw 1503 to drive the Y-axis slider 1501, the two Z-axis connecting rods 1416 and the X-axis motion mechanism 1300, the two support rod assemblies 1200 which are arranged on the X-axis support frame 1301 are moved, and the two Z-axis guide blocks 1417 and the Z-axis slider 1401 remain in place.

[0044] Fig. Figure 8 is a schematic top view of the two support rods 1201 and the Z-axis horizontal lifting rod 1409 of the reflow oven 1000 of the embodiment in Fig. 1 to move the bowl T1. As in the Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig.As shown in Figure 8, the two X-axis drive components 1304 each drive the X-axis drive gears 1303 and the two X-axis motion gears 1306 when the shell T1 is to be moved. The X-axis drive gears 1303 rotate the two roller gears 1202 to roll the two support rod assemblies 1200 along the X-axis. The two X-axis motion gears 1306 each rotate relative to the two racks 1305, allowing the two support rod assemblies 1200, arranged on the X-axis motion mechanism 1300, to move along the X-axis from a separating position to the closing position relative to each other. The two support rod assemblies 1200 are located below the shell T1.The Z-axis drive component 1402 drives the Z-axis slider 1401 via the Z-axis screw 1406, the Z-axis slider 1401 moves the two support rod assemblies 1200 arranged on the X-axis support frame 1301, and the Z-axis drive component 1402 can further drive the Z-axis helicopter 1415 to move the Z-axis lifting platform 1411, the two Z-axis lifting connecting rods 1410 and the Z-axis horizontal lifting rod 1409 simultaneously, thereby raising the two support rod assemblies 1200 to touch and lift the shell T1. The Y-axis drive component 1502 drives the Y-axis slider 1501 via the Y-axis screw 1503, which moves the two Z-axis connecting rods 1416 and the X-axis support frame 1301, so that the two support rod assemblies 1200 arranged on the X-axis support frame 1301 can move along the Y-axis, thereby moving the shell T1 from the first position to the second position.The Z-axis drive component 1402 can be driven in reverse to move the Z-axis slider 1401 via the Z-axis screw 1406, thereby causing movements of the two support rod assemblies 1200 arranged on the X-axis support frame 1301. The Z-axis drive component 1402 also drives the Z-axis helicopter 1415 to raise the Z-axis lifting platform 1411, simultaneously driving the two Z-axis lifting connecting rods 1410 and the Z-axis horizontal lifting rod 1409, thus lowering the two support rod assemblies 1200 to separate from the shell T1. The process can therefore be repeated to move the shell T1 to a predetermined position.
