[0002] Photovoltaic diodes are a type of semiconductor device widely used in the new energy industry. They can convert light energy into electrical energy. At the same time, photovoltaic diodes also prevent electrical energy from flowing back to the external power grid and causing waste. In the production process of diodes, after the diodes are welded, they need to be cured again because of the phenomenon of virtual connection, so as to improve the stability of the photovoltaic diodes. Reflow soldering is the most commonly used method for curing photovoltaic diodes.

Detailed implementation manners

[0033] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0034] Please refer to Figures 1 to 16As shown in the figure, the present invention provides a technical solution: a reflow soldering device for photovoltaic diode production, including a progressive component 1, a support component 2, a propulsion component 3, an adjustment component 4, and a heating component 5. The progressive component 1 includes a progressive rotating shaft 105, which is rotatably connected to a support frame 102. A progressive support plate 106 is rotatably connected to the progressive rotating shaft 105. A second belt 107 is frictionally connected to the progressive rotating shaft 105. A progressive plate 108 is slidably connected to the progressive support plate 106. The support component 2 includes a first rotating shaft 205, which is rotatably connected to a support plate 202. A connecting plate 206 is slidably connected to the first rotating shaft 205. A second rotating shaft 207 is rotatably connected to the connecting plate 206, and the second rotating shaft 207 is also rotatably connected to the progressive plate 108 at the same time. The propulsion component 3 includes a propulsion support plate 306, which is fixedly connected to a chain 305. A propulsion slide bar 307 is slidably connected to the propulsion support plate 306. A propulsion block 309 is fixedly connected to the propulsion slide bar 307. The first end of a propulsion spring 308 is fixedly connected to the propulsion block 309, and the second end of the propulsion spring 308 is fixedly connected to the propulsion support plate 306. The adjustment component 4 includes a sliding rotating shaft 406, which is slidably connected to a slide plate 401. The first end of a first connecting rod 407 is rotatably connected to the sliding rotating shaft 406, and the second end of the first connecting rod 407 is rotatably connected to a second connecting rod 408. The second connecting rod 408 is fixedly connected to the support plate 202.

[0035] The progressive component 1 further includes a bottom plate 101, on which a support frame 102 is fixedly connected. There are two support frames 102. A progressive motor 103 is fixedly connected to the bottom plate 101. The first end of a first belt 104 is frictionally connected to the progressive motor 103, and the second end of the first belt 104 is frictionally connected to the progressive rotating shaft 105.

[0036] As Figure 5 and Figure 6As shown, there are four progressive rotating shafts 105, with two in a group. The two groups of progressive rotating shafts 105 are oppositely arranged on two support frames 102. Each group of progressive rotating shafts 105 is fixedly connected by a connecting rod. When the progressive rotating shafts 105 rotate, the end of the progressive rotating shaft 105 connected to the progressive support plate 106 will perform circular motion around the end of the progressive rotating shaft 105 connected to the first belt 104. The first belt 104 is frictionally connected to the progressive rotating shaft 105 on the side close to the progressive motor 103. The two ends of the second belt 107 are respectively frictionally connected to the two progressive rotating shafts 105 on the side far from the progressive motor 103. A plurality of card slots are provided on the progressive plate 108. During operation, the progressive motor 103 drives one progressive rotating shaft 105 to rotate through the first belt 104, and the progressive rotating shaft 105 drives other progressive rotating shafts 105 to rotate through the second belt 107, so as to realize the synchronous rotation of the four progressive rotating shafts 105. When the four progressive rotating shafts 105 rotate, the two middle connecting rods start to move around the progressive rotating shafts 105. The movement of the middle connecting rods drives the progressive support plate 106 to move, and the movement of the progressive support plate 106 drives the progressive plate 108 to move. The diode 109 is pushed through the movement of the progressive plate 108, so that the diode 109 is pushed once when the progressive rotating shaft 105 rotates one circle.

[0037] The support assembly 2 further includes a chute plate 201. The chute plate 201 is fixedly connected to the support frame 102. A support plate 202 is slidably connected to the chute plate 201. There are two support plates 202. A support slide bar 203 is fixedly connected to the support plate 202. The support slide bar 203 is slidably connected to the chute plate 201. The first end of a support slide bar spring 204 is fixedly connected to the support plate 202, and the second end of the support slide bar spring 204 is fixedly connected to the chute plate 201.

[0038] As Figure 4 and Figure 7As shown in the figure, two support plates 202 are respectively slidably connected to two chute plates 201 on both sides. Multiple card slots are provided on the support plates 202. Two support slide bars 203 are provided on each support plate 202. A support slide bar spring 204 is sleeved on each support slide bar 203. The support slide bars 203 are in a compressed state. Four connecting plates 206 are provided. Every two of them are grouped and respectively arranged on two support plates 202. At the same time, each group of connecting plates 206 is connected to a progressive plate 108. During operation, if the diode 109 is small, the support slide bars 203 reset to push the two support plates 202 to slide towards the middle. The two support plates 202 slide towards the middle and support both ends of the diode 109. At the same time, the sliding of the support plates 202 drives the support slide bars 203 to slide and the first rotating shafts 205 to move. The first rotating shafts 205 on both sides move towards the middle to push the connecting plates 206 towards the middle. When the connecting plates 206 move towards the middle, they push the progressive plates 108 on both sides towards the middle through the second rotating shafts 207. At the same time, when the diode 109 is large, it pushes the two support plates 202 to slide towards both sides. The two support plates 202 slide towards both sides to push the support slide bars 203 to slide and compress the support slide bar springs 204. When the two support plates 202 slide towards both sides, they pull the two connecting plates 206 towards both sides through the first rotating shafts 205. When the connecting plates 206 move towards both sides, they pull the two progressive plates 108 to slide towards both sides through the second rotating shafts 207. Thus, it realizes that the middle width between the two support plates 202 changes according to the size of the diode 109, and at the same time, through transmission, the progressive plates 108 move synchronously, so that the progressive plates 108 can still push the diode 109 after the support plates 202 move.

[0039] When the progressive plate 108 pushes the diode 109, the connecting plate 206 rotates around the first rotating shaft 205, so that when the progressive plate 108 pushes the diode 109, one end of the progressive plate 108 will not be transmitted to the support plate 202 through the connecting plate 206, thus causing the support plate 202 to deform or get stuck. At the same time, when the connecting plate 206 rotates to the uppermost position, the connecting plate 206 slides down a certain distance. The connecting plate 206 slides down one end, playing a role in avoiding the diode 109 transmitted above the support plate 202.

[0040] The propulsion assembly 3 further includes a first support frame 301 and a driven wheel 304. The first support frame 301 is fixedly connected to the support frame 102. A housing 303 is fixedly connected to the first support frame 301. Two groups of driven wheels 304 are provided. The two groups of driven wheels 304 are respectively rotatably connected to the first support frame 301 and the second support frame 302. A chain 305 is frictionally connected to the driven wheels 304. The chain 305 is also frictionally connected to the driving wheel 313.

[0041] The propulsion assembly 3 further includes a second support frame 302. The second support frame 302 is fixedly connected to the support frame 102. A handle 310 is rotatably connected to the second support frame 302. A handle gear 311 is fixedly connected to the handle 310. A driving wheel 313 is rotatably connected to the second support frame 302. A transmission gear 312 is fixedly connected to the driving wheel 313. The transmission gear 312 meshes with the handle gear 311.

[0042] As Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, the first support frame 301 and the second support frame 302 are respectively arranged on the two support frames 102. Driven wheels 304 are arranged on both the first support frame 301 and the second support frame 302. A plurality of propulsion support plates 306 are arranged in an array on the chain 305. A propulsion block 309 is arranged on each propulsion support plate 306. The propulsion spring 308 is in a compressed state. During operation, the propulsion block 309 is pushed by the resilience of the propulsion spring 308 to closely adhere to the diode 109. When the progressive plate 108 propels the diode 109, the diode 109 first rises and moves to the right. When the diode 109 moves, the diode 109 pushes the propulsion block 309 to move. The movement of the propulsion block 309 drives the propulsion support plate 306 to move through the propulsion support plate 306. The movement of the propulsion support plate 306 drives the chain 305 to frictionally move on the driven wheel 304. Since the chain 305 is sleeved on the driven wheels 304 at both ends, all the propulsion blocks 309 perform synchronous cyclic movement around the chain 305. When the propulsion blocks 309 perform cyclic movement, the propulsion blocks 309 that are close to the slide plate 401 once gradually move to move downward as they are pushed. During the downward movement of the propulsion block 309, the propulsion block 309 contacts the diode 109 placed on the slide plate 401. Then, as the diode 109 on the progressive plate 108 is continuously propelled, the propulsion block 309 drives the diode 109 on the slide plate 401 to slide. The propulsion block 309 pushes the diode 109 placed on the slide plate 401 to slide onto the support plate 202. After the diode 109 is pushed onto the support plate 202, it can be pushed by the progressive plate 108, thereby realizing a cycle of continuous progression and simultaneous continuous feeding, achieving the effect of continuous operation.

[0043] In the initial state, since there is no diode 109 on the support plate 202, when the progressive plate 108 moves, it cannot push the propulsion block 309 to move through the diode 109, so the chain 305 will not move. At this time, it is necessary to manually rotate the handle 310. The rotation of the handle 310 drives the handle gear 311 to rotate. The rotation of the handle gear 311 drives the transmission gear 312 to rotate. The rotation of the transmission gear 312 drives the driving wheel 313 to rotate. The rotation of the driving wheel 313 drives the chain 305 to move. After the chain 305 moves, it drives the propulsion block 309 to move. The movement of the propulsion block 309 pushes the diode 109 placed on the slide plate 401 onto the support plate 202. After there is one diode 109 on the support plate 202, stop rotating the handle 310. At the same time, after there is one diode 109 on the support plate 202, the progressive plate 108 can drive the chain 305 to move by progressing the first diode 109, so as to realize the cyclic movement of the propulsion block 309 and achieve the effect of automatic connection work.

[0044] The adjusting assembly 4 further includes a slide plate 401. The slide plate 401 is fixedly connected to the bottom plate 101. A flap frame 402 is fixedly connected to the slide plate 401. A flap 403 is rotatably connected to the flap frame 402. A limiting strip 405 is fixedly connected to the slide plate 401.

[0045] The first end of a torsion spring 404 is fixedly connected to the flap 403. The second end of the torsion spring 404 is fixedly connected to the flap frame 402.

[0046] Such as Figure 12 、 Figure 13 And Figure 14As shown, the skateboard 401 is an inclined board. On both sides of the top of the skateboard 401, there is a flap frame 402 respectively. Under the action of the torsion spring 404, the flap 403 blocks the downward sliding of the diode 109 on the skateboard 401. The limit strips 405 are arranged on both sides of the skateboard 401 to prevent the diode 109 on the skateboard 401 from deviating too much from the center of the skateboard 401. There are two sliding rotating shafts 406, which are respectively slidably connected to both sides of the skateboard 401. When the first connecting rod 407 is in the initial state, when the support slide bar spring 204 pushes the support plate 202 to move closer to the middle, a slope is formed. The two second connecting rods 408 are respectively fixedly connected to the two support plates 202. During operation, the diode 109 is manually or conveyed to the top of the skateboard 401 through a conveying device. After the diode 109 is conveyed to the top of the skateboard 401, it slides downward and is blocked by the flap 403, so that the diode 109 stops sliding downward. Then, the movement of the pushing block 309 continues to push the diode 109 downward. When the pushing block 309 pushes the diode 109 downward, the diode 109 pushes the flap 403 to flip and compress the torsion spring 404. After the first diode 109 completely passes under the flap 403, the flap 403 resets under the rebound of the torsion spring 404 and blocks the subsequent diodes 109 again. As the progressive motor 103 continues to push the diode 109 downward, both ends of the diode 109 gradually contact the slope formed by the first connecting rod 407, so that the diode 109 moves to the center of the skateboard 401. At the same time, with the continuous pushing of the pushing block 309, the diode 109 pushes the first connecting rod 407 to rotate. When the first connecting rod 407 rotates, it pushes the sliding rotating shaft 406 to slide upward. When the two first connecting rods 407 rotate, they also drive the two second connecting rods 408 to slide toward both sides of the skateboard 401. The sliding of the second connecting rod 408 drives the support plate 202 to slide, so as to realize the control of the width between the two support plates 202 according to the size of the diode 109. After the width between the two support plates 202 reaches an appropriate value, when the subsequent diodes 109 slide downward, they will not push the first connecting rod 407 to rotate again, and only make the diode 109 move to the center of the skateboard 401 during the downward sliding process through the slope formed by the first connecting rod 407.

[0047] When it is necessary to produce diodes 109 of other sizes, the feeding of diodes 109 to the skateboard 401 is stopped. After there is no diode 109 in the device, the device reaches the initial state. Then, the diodes 109 of other sizes to be produced are placed on the skateboard 401, and then the above steps are repeated to realize the adaptive adjustment of the device.

[0048] The heating assembly 5 includes a heating chamber 501, which is fixedly connected to the chute plate 201. A heating pipe 502 is fixedly connected to the heating chamber 501. A conveying pipe 503 is fixedly connected to the heating pipe 502. An air outlet 504 is fixedly connected to the conveying pipe 503.

[0049] As Figure 15 and Figure 16 shown, there are two sets of heating tubes 502, which are respectively arranged on both sides of the heating chamber 501. A delivery pipe 503 is arranged on the side of each heating tube 502 close to the diode 109. A blower is arranged inside the delivery pipe 503. During operation, the heating tubes 502 on both sides are started, and then the blower inside the delivery pipe 503 is started, so that the external air passes through the heating tubes 502 for heating. After heating, the hot air enters the air outlet 504 through the delivery pipe 503, and the diode 109 transferred from the support plate 202 is heated through the air outlet 504. Through the transfer of the progressive plate 108, the diode 109 gradually enters the interior of the heating chamber 501 to achieve gradual temperature rise. Then, through the progression of the progressive plate 108, the diode 109 is transmitted from the other end of the heating chamber 501, thereby realizing the reflow soldering process of the diode 109.

[0050] Working principle: When in use, first start the heating tube 502 and the internal fan of the conveying pipe 503 for preheating. Then, manually or through the conveying device, convey the diode 109 above the slide plate 401, and let the diode 109 slide down along the slide plate 401. After the diode 109 touches the flap 403, manually rotate the handle 310. The rotation of the handle 310 drives the rotation of the handle gear 311. The handle gear 311 drives the rotation of the transmission gear 312, causing the driving wheel 313 to rotate. After the driving wheel 313 rotates, it drives the movement of the pushing block 309 through the chain 305. The pushing block 309 pushes the diode 109 to slide down along the slide plate 401. The diode 109 slides down and pushes the flap 403 to rotate and compress the torsion spring 404. After the diode 109 passes through the flap 403, the flap 403 resets through the torsion spring 404 to block the subsequent diode 109. The diode 109 continues to slide down and touches the first connecting rod 407, and then pushes the first connecting rod 407 to rotate. The rotation of the first connecting rod 407 drives the sliding of the sliding rotating shaft 406, and at the same time drives the sliding of the support plate 202 through the second connecting rod 408. The sliding of the support plate 202 compresses the support slide bar spring 204. The sliding of the support plate 202 also drives the synchronous sliding of the progressive plate 108 through the connecting plate 206. At the same time, when the diode 109 pushes the first connecting rod 407, it moves to the center of the slide plate 401 through the reaction force of the first connecting rod 407. Then, the diode 109 slides along the slide plate 401 to the first card slot of the support plate 202. After the diode 109 moves to the first card slot of the support plate 202, stop rotating the handle 310 and start the progressive motor 103, so that the progressive motor 103 drives the movement of the progressive plate 108 through transmission. Through the movement of the progressive plate 108, the first diode 109 is pushed to the second card slot on the support plate 202. At the same time, the progressive plate 108 drives the pushing block 309 through the diode 109, and the pushing block 309 drives the movement of the chain 305. The movement of the chain 305 causes the subsequent pushing block 309 to push another diode 109 above the slide plate 401 to the second card slot of the support plate 202. Then, through the continuous rotation of the progressive motor 103, the diode 109 is pushed into the reflow soldering process inside the heating chamber 501. Then, only by continuously placing the diode 109 above the slide plate 401 and continuously operating the progressive motor 103, continuous production can be achieved. At the same time, when it is necessary to replace diodes 109 of other sizes, only after discharging the existing diodes 109 on the device and then repeating the above steps can the adjustment be automatically realized.
