[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0023] like Figures 1-10 As shown, the present invention proposes an SMD material supply device, including a housing 1, a first conveyor belt 3 installed on the top of the housing 1, four sets of progressive gears 4 installed on one side of the top of the housing 1, a control plate 5 installed on the other side of the top of the housing 1, a first hydraulic rod 6 fixedly connected inside the housing 1, a baffle 7 fixedly connected to one side of the inner wall of the housing 1, a push plate 8 fixedly connected to the output end of the first hydraulic rod 6, and the push plate 8 being disposed at the bottom of the baffle 7. The SMD material supply device also includes a dehumidification component for treating humid air during material transmission, the dehumidification component including a drying structure and a uniform structure, and a transfer component for transferring SMD materials.
[0024] To address the impact of humid environments on SMD material supply, when supplying tape resistors, the tape resistors can be placed at the top of the housing 1 with their bottoms against the first conveyor belt 3. The control board 5 then starts the operation of the first conveyor belt 3 and the advancing gear 4, which transfer the tape resistors to one side. A drying structure dries the air around the tape resistors passing through the first conveyor belt 3, creating a relatively dry environment. A uniform structure generates a slight airflow, which absorbs humid air. When a set of resistors is transferred above the baffle 7, the first hydraulic rod 6 pushes the push plate 8 upwards. As the push plate 8 moves upwards, it works with the baffle 7 to cut off a set of resistors, holding them on the baffle 7. The cut resistors can then be transferred out via a transfer assembly.
[0025] As one implementation method, such as Figure 3 and Figure 4 The drying structure is used to dry the surface of SMD materials. The drying structure includes a top plate 2, which is fixed to the top of the outer shell 1. A second conveyor belt 9 is installed on the inner wall of the top plate 2. The second conveyor belt 9 is located at the top of the first conveyor belt 3. A storage box 10 is fixed to the surface of the second conveyor belt 9. The storage box 10 is made of non-woven fabric and is filled with desiccant. Multiple sets of storage boxes 10 are provided and are distributed in parallel on the outer wall of the second conveyor belt 9.
[0026] By driving the second conveyor belt 9 to run slowly, multiple externally installed storage boxes 10 can be driven to rotate slowly at the same time. Since the storage box 10 is made of breathable non-woven fabric, the desiccant inside the storage box 10 can absorb the humid air inside the top plate 2. The second conveyor belt 9 can then cause multiple storage boxes 10 to take turns absorbing the humid air. Since the second conveyor belt 9 is located at the top of the first conveyor belt 3 and is close to the tape resistor, it can absorb the humid air inside the top plate 2 in advance, keeping the area around the tape resistor relatively dry.
[0027] As one implementation method, such as Figure 3 and Figure 4 The uniform structure facilitates the adsorption of surrounding humid air by the drying structure. The uniform structure includes a first pulley 11, which is fixed to the drive shaft of the second conveyor belt 9. A transmission belt 12 is sleeved on the outer wall of the first pulley 11, and a second pulley 13 is sleeved on the other side of the inner wall of the transmission belt 12. A guide tube 16 is fixed to the top of the top plate 2, and a fixing frame 17 is fixed to the inner wall of the guide tube 16. A rotating rod 14 is rotatably connected to the inner wall of the fixing frame 17. One end of the rotating rod 14 is fixed to the center of the second pulley 13, and a fan blade 15 is fixed to the outer wall of the rotating rod 14. A filter screen 18 is installed on one side of the guide tube 16, and a guide plate 19 is fixed to the inner wall of the top plate 2. Multiple sets of guide plates 19 are provided.
[0028] When the second conveyor belt 9 runs at a slow speed, it drives the first pulley 11 on the drive shaft to rotate. When the first pulley 11 rotates, it drives the transmission belt 12 on the outer wall to rotate. The transmission belt 12 can then drive the second pulley 13, the rotating rod 14, and the fan blade 15 to rotate together. When the fan blade 15 rotates, due to the slow speed, a weak airflow is generated to one side. The airflow is transmitted to the interior of the top plate 2 through the guide pipe 16. By setting multiple sets of guide plates 19 inside the top plate 2, the airflow can be dispersed and guided until the weak airflow is evenly diffused into the interior of the top plate 2. The multiple sets of weak airflow can cause a slight flow of air inside the top plate 2, thereby causing the humid air to be absorbed.
[0029] As one implementation method, such as Figures 6-10 The transfer assembly includes a first motor 20, which is fixed to the top of the housing 1. A circular plate 21 is fixed to the output shaft of the first motor 20. A second hydraulic rod 22 is fixed to the bottom of the circular plate 21. A vertical rod 23 is fixed to the bottom of the second hydraulic rod 22. A side plate 24 is fixed to one side of the vertical rod 23. A support plate 25 is rotatably connected to the bottom of the vertical rod 23. A first locking tooth 26 is fixed to one side of the support plate 25. A horizontal plate is fixed to one side of the housing 1. A third conveyor belt is installed inside the horizontal plate. An installation groove 27 is provided on one side of the vertical rod 23. A locking structure is provided inside the installation groove 27.
[0030] After the resistor is cut off, a second hydraulic rod 22 can be activated, pushing the vertical rod 23 downwards. The side plate 24 and support plate 25 on the vertical rod 23 will also move downwards along with the vertical rod 23. When the support plate 25 contacts the top of the push plate 8, the interaction force between the vertical rod 23 and the support plate 25 will flip the support plate 25 to one side until the support plate 25 slides below the set of resistors. As the vertical rod 23 moves downwards, the side plate 24 will also move downwards. The locking structure can fix the position of the support plate 25 when the support plate 25 is parallel to the side plate 24, so that a set of resistors can be clamped by the support plate 25 and the side plate 24. After clamping a set of resistors, a set of second hydraulic rods 22 can be retracted to move a set of vertical rods 23, support plate 25, side plate 24 and resistors upward. The first motor 20 drives the circular plate 21 to rotate, so that the set of vertical rods 23, support plate 25 and side plate 24 that clamped the resistors can be rotated to one side together, which facilitates the transfer of the next set of resistors.
[0031] As one implementation method, such as Figures 6-10The locking structure includes a slide rod 28, which is slidably connected inside the mounting groove 27. The bottom of the mounting groove 27 has a circular groove. A circular rod 29 is fixedly connected to the bottom of one side of the slide rod 28. The circular rod 29 is slidably connected to the inner wall of the circular groove. A second locking tooth 31 is fixedly connected to the bottom of the circular rod 29. A first spring 30 is fixedly connected to the top of the second locking tooth 31. The first spring 30 is fixedly connected to the inner wall of the circular groove. A square plate 32 is fixedly connected to the top of the horizontal plate.
[0032] When a set of resistors is clamped by the vertical rod 23, side plate 24, and support plate 25, the support plate 25 will flip when it touches the push plate 8. The first locking tooth 26 on the support plate 25 will also flip along with it until the first locking tooth 26 flips to one side of the second locking tooth 31. Since both the first locking tooth 26 and the second locking tooth 31 have inclined surfaces at this time, when the first locking tooth 26 touches one side of the second locking tooth 31, the second locking tooth 31 can be pushed upward by the first locking tooth 26 continuing to flip to one side. The first locking tooth 26 will then pass through the second locking tooth 31 by squeezing the first spring 30. After the first locking tooth 26 passes through the second locking tooth 31, the second locking tooth 31 can be moved downward by the restoring force of the first spring 30 to reset the position of the first locking tooth 26 and the support plate 25. When the vertical rod 23, side plate 24, and support plate 25 that hold the resistors move to the top of the third conveyor belt, the second hydraulic rod 22 can be activated to move the vertical rod 23, side plate 24, and support plate 25 downward. When the sliding rod 28 on one side of the vertical rod 23 contacts the square plate 32, it will be blocked by the square plate 32. As the vertical rod 23 continues to move downward, the sliding rod 28 can be pushed upward. When the sliding rod 28 moves, it will pull the round rod 29 and the second locking tooth 31 to move upward and squeeze the first spring 30 until the second locking tooth 31 moves away from one side of the first locking tooth 26. This will cause the support plate 25 to lose its lock and flip downward, thereby placing a set of resistors between the support plate 25 and the side plate 24 onto the third conveyor belt. The third conveyor belt is equipped with multiple sets of rubber arc-shaped pads to protect the resistors.
[0033] like Figure 11 and Figure 12 A horizontal frame 33 is fixed to one side of the outer casing 1, a mounting plate 34 is fixed to one side of the horizontal frame 33, a second motor 35 is fixed to one side of the mounting plate 34, and a winding wheel 36 is fixed to the output shaft of the second motor 35. The mounting plate 34, the second motor 35 and the winding wheel 36 are all provided in two sets and are symmetrically distributed on both sides of the horizontal frame 33.
[0034] After the tape resistance is cut off, the remaining tape waste will continue to be conveyed to one side by the first conveyor belt 3. One end of the tape waste can be fixed on the take-up roller 36, and the two sets of second motors 35 can be started to drive the two sets of take-up rollers 36 to rotate. The rotation frequency of the two sets of second motors 35 is the same as the frequency of the first conveyor belt 3, so the tape waste on both sides can be successfully wound up and collected.
[0035] like Figure 11 and Figure 12 An L-shaped plate 37 is fixedly connected to one side of the outer shell 1. A third motor 38 is fixedly connected to one side of the L-shaped plate 37. A bidirectional screw 39 is fixedly connected to the output shaft of the third motor 38. A nut 40 is threadedly connected to the outer wall of the bidirectional screw 39. A connecting plate 42 is fixedly connected to one side of the nut 40. Two sets of limiting plates 43 are fixedly connected to one side of the connecting plate 42. The two sets of limiting plates 43 are arranged on both sides of the take-up roller. A slider 41 is fixedly connected to the bottom of the nut 40. A sliding groove is opened at the top of the cross frame 33. The slider 41 is slidably connected to the inner wall of the sliding groove.
[0036] When winding up the tape waste, four sets of limiting plates 43 can be used to limit the two sides of the winding wheel 36 to prevent deviation during winding. After a batch of tape resistance is supplied, the third motor 38 can be started, and the third motor 38 drives the bidirectional screw 39 to rotate. When the bidirectional screw 39 rotates, it will drive the two sets of nuts 40 and the connecting plate 42 to move towards the center together, and also cause the four sets of limiting plates 43 to move towards the center together. When the four sets of limiting plates 43 move, they will push the tape waste collected on the winding wheel 36 until the edge tape waste is removed from the winding wheel 36, which makes it easier to centrally process the tape waste.
[0037] like Figure 13 A second spring 44 is fixedly connected to the inner wall of the connecting plate 42. A mounting frame 45 is fixedly connected to one side of the second spring 44. A pressure roller 46 is rotatably connected to the inner wall of the mounting frame 45. A guide groove is provided on the inner wall of the connecting plate 42. Guide strips 47 are fixedly connected to both sides of the mounting frame 45. Two sets of guide strips 47 are slidably connected in the guide groove.
[0038] When winding up the tape waste, the outer tape waste will press against the pressure roller 46. As more and more layers of tape waste are collected, the pressure roller 46 will be gradually pushed to one side. By setting the guide strip 47 and guide groove, the pressure roller 46 and the mounting frame 45 can be limited when moving. A second spring 44 is set on one side of the pressure roller 46. Therefore, when the pressure roller 46 moves to one side, it will squeeze the second spring 44 to generate a reaction force, causing the pressure roller 46 to return to one side. Therefore, the tape waste can be more compacted when packaged.
[0039] like Figure 5An inclined plate 48 is fixed to the side of the outer shell 1 away from the horizontal frame 33. Three sets of pulleys 49 are rotatably connected to the inner wall of the inclined plate 48. Two sets of inclined plates 48 are provided and are symmetrically distributed on one side of the outer shell 1.
[0040] When the tape resistor is placed on the first conveyor belt 3, it can be guided into the interior of the top plate 2 by two sets of inclined plates 48, and by setting three sets of pulleys 49, when the edge of the tape resistor contacts the pulleys 49, the pulleys 49 will keep the tape resistor in the center position.
[0041] An SMD production system includes the aforementioned SMD material supply equipment. To address the impact of humid environments on the SMD material supply process, when supplying tape resistors, the tape resistor can be placed on the top of the housing 1, with its bottom attached to the first conveyor belt 3. An inclined plate 48 and pulley 49 ensure the tape resistor is centered. The first conveyor belt 3 and the advancing gear 4 are then activated via a control board 5, and the tape resistor is transferred to one side via the first conveyor belt 3 and the advancing gear 4. Driving a second conveyor belt 9 at a slow speed simultaneously rotates multiple externally mounted storage boxes 10. Since the storage boxes 10 are made of breathable non-woven fabric, the desiccant inside can absorb humid air from the top plate 2. The second conveyor belt 9 causes multiple storage boxes 10 to alternately absorb humid air. Because the second conveyor belt 9 is located on the first conveyor belt 2... The top of the conveyor belt 3 is close to the tape resistor, so it can adsorb the humid air in the top plate 2 in advance, keeping the area around the tape resistor relatively dry. When the second conveyor belt 9 runs slowly, it will drive the first pulley 11 on the drive shaft to rotate. When the first pulley 11 rotates, it will drive the transmission belt 12 on the outer wall to rotate. The transmission belt 12 can drive the second pulley 13, the rotating rod 14 and the fan blade 15 to rotate together. When the fan blade 15 rotates, due to the slow speed, it will generate a weak airflow to one side. The airflow will be transmitted to the inside of the top plate 2 through the guide pipe 16. By setting multiple sets of guide plates 19 inside the top plate 2, the airflow can be dispersed and guided until the weak airflow is guided and evenly diffused into the inside of the top plate 2. The multiple sets of weak airflow can cause the air in the top plate 2 to move slightly, thereby causing the humid air to be adsorbed. When a set of resistors is passed to the top of the baffle 7, the push plate 8 can be pushed upward by activating the first hydraulic rod 6. As the push plate 8 moves upward, it can work with the baffle 7 to cut off a set of resistors and hold them on the baffle 7. After the resistors are cut off, a second hydraulic rod 22 can be activated, and the vertical rod 23 can be pushed downward by the second hydraulic rod 22. The side plate 24 and the support plate 25 provided on the vertical rod 23 will also move downward along with the vertical rod 23. When the support plate 25 contacts the top of the push plate 8, the interaction force between the vertical rod 23 and the support plate 25 will flip the support plate 25 to one side until the support plate 25 slides to the bottom of the set of resistors. As the vertical rod 23 moves downward, the side plate 24 also moves downward. When the support plate 25 flips, the first locking tooth 26 on the support plate 25 flips along with it until it flips to one side of the second locking tooth 31. Since both the first locking tooth 26 and the second locking tooth 31 have inclined surfaces at this time, when the first locking tooth 26 is against one side of the second locking tooth 31, the second locking tooth 31 can be pushed upward by the first locking tooth 26 continuing to flip to one side. The first locking tooth 26 is then pushed through the second locking tooth 31 by the compression of the first spring 30. After the first locking tooth 26 passes through the second locking tooth 31, it can be pushed upward by the first spring. The reset force of 30 pushes the second clamping tooth 31 downward to reset, thereby fixing the position of the first clamping tooth 26 and the support plate 25. This allows the support plate 25 and the side plate 24 to clamp a set of resistors. After clamping a set of resistors, a second hydraulic rod 22 can be retracted to move a set of vertical rods 23, the support plate 25, the side plate 24, and the resistors upward. The first motor 20 drives the circular plate 21 to rotate, causing the set of vertical rods 23, the support plate 25, and the side plate 24 that clamped the resistors to rotate together to one side, facilitating the transfer of the next set of resistors. When the set of vertical rods 23, the side plate 24, and the support plate 25 that clamped the resistors moves to the top of the third conveyor belt, the conveyor belt can be opened. The second hydraulic rod 22 moves the vertical rod 23, side plate 24 and support plate 25 downward. When the sliding rod 28 on one side of the vertical rod 23 contacts the square plate 32, it will be blocked by the square plate 32. As the vertical rod 23 continues to move downward, the sliding rod 28 can be pushed upward. When the sliding rod 28 moves, it will pull the round rod 29 and the second locking tooth 31 to move upward and squeeze the first spring 30 until the second locking tooth 31 moves away from one side of the first locking tooth 26. This will cause the support plate 25 to lose its lock and flip downward, thereby placing a set of resistors between the support plate 25 and the side plate 24 onto the third conveyor belt. The third conveyor belt is equipped with multiple sets of rubber arc-shaped pads to protect the resistors. After the tape resistance is cut off, the remaining tape waste is conveyed to one side by the first conveyor belt 3. One end of the tape waste can be fixed to the take-up roller 36, and the two sets of second motors 35 are started to drive the two sets of take-up rollers 36 to rotate. The rotation frequency of the two sets of second motors 35 is the same as the frequency of the first conveyor belt 3, so the tape waste on both sides can be smoothly collected and wound up. At the same time, the two sides of the take-up roller 36 can be limited by four sets of limit plates 43 to prevent deviation during winding. As more and more layers of tape waste are collected, the pressure roller 46 will be gradually pushed to one side. By setting guide strips 47 and guide grooves, the movement of the pressure roller 46 and the mounting frame 45 can be limited. A second spring 44 is provided on one side of the pressure roller 46. Therefore, when the pressure roller 46 moves to one side, it will squeeze the second spring 44 to generate a reaction force, causing the pressure roller 46 to return to one side. This makes the tape waste more compact when packaging. After a batch of tape resistance is supplied, the third motor 38 can be started, and the bidirectional screw 39 will be rotated by the third motor 38. When the bidirectional screw 39 rotates, it will drive the two sets of nuts 40 and the connecting plate 42 to move together towards the center, and also cause the four sets of limiting plates 43 to move together towards the center. When the four sets of limiting plates 43 move, they will push the tape waste collected on the take-up roller 36 until the edge tape waste is removed from the take-up roller 36, which makes it easier to centrally process the tape waste.
