Description

Technical Field

[0001] This utility model relates to the field of circuit board surface mount production line technology, and in particular to a dual-track connection platform. Background Technology

[0002] A PCB surface mount technology (SMT) production line is used to automatically mount electronic components onto PCBs. It typically includes, in sequence, mounting equipment, solder paste printing equipment, solder paste inspection equipment, component mounting equipment, mounting inspection equipment, and cooling equipment. Adjacent equipment is connected via a transfer platform to transport PCBs. To improve processing efficiency, some manufacturers employ a dual-line synchronous processing solution. Between the mounting inspection and cooling equipment on the two production lines, a transfer device and a double-track transfer platform are installed. The transfer device transports PCBs from the mounting inspection equipment on both lines to the double-track transfer platform, which then transports the PCBs from the transfer device to the cooling equipment. The cooling equipment simultaneously cools the PCBs from both production lines.

[0003] Currently, dual-track connection platforms typically include two conveyor modules for transporting circuit boards. Each module includes two conveyor belts and an adjustment mechanism for adjusting the distance between the two conveyor belts. The conveyor belts integrate conveyor drive components that drive the conveyor belts to transport the circuit boards. The adjustment mechanism drives the two conveyor belts and their corresponding conveyor drive components to move synchronously. In this aforementioned solution, because the conveyor drive components are integrated onto the conveyor belts, the conveyor belt structure is relatively complex, with a cluttered arrangement of parts, which is not conducive to subsequent equipment maintenance.

[0004] Therefore, how to provide a relatively neat dual-track docking platform solution has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Please see Figures 1 to 9 This embodiment discloses a dual-track connecting platform, including a frame, guide rods 23, a first lead screw mechanism, a second lead screw mechanism, and a conveying module 20. The frame includes a housing 10, within which are spaced-apart first vertical plates 31 and second vertical plates 32. Specifically, the first and second vertical plates 31 and 32 are fixed to the inner wall of the housing 10 by fasteners. At least two guide rods 23 are provided, with both ends of each guide rod 23 fixed to the first and second vertical plates 31 and 32, respectively.

[0022] The first lead screw mechanism includes a first lead screw shaft 24 and a first lead screw motor 241. The first lead screw shaft 24 is parallel to the guide rod 23, and its two ends are rotatably connected to a first vertical plate 31 and a second vertical plate 32. The first lead screw motor 241 is located on the outer side of the first vertical plate 31. Specifically, the first lead screw motor 241 can be fixed to the outer wall of the first vertical plate 31 or the inner wall of the housing 10 by fasteners. The first lead screw motor 241 is configured to drive the first lead screw shaft 24 to rotate in both directions.

[0023] The second lead screw mechanism includes a second lead screw shaft 25 and a second lead screw motor 251. The second lead screw shaft 25 is parallel to the guide rod 23, and its two ends are rotatably connected to the first vertical plate 31 and the second vertical plate 32. The second lead screw motor 251 is located on the outside of the first vertical plate 31. Specifically, the second lead screw motor 251 can be fixed to the outer wall of the first vertical plate 31 or the inner wall of the housing 10 by fasteners. The second lead screw motor 251 is configured to drive the second lead screw shaft 25 to rotate in both directions.

[0024] The conveying module 20 includes a first conveying motor 271, a second conveying motor 261, a first connecting shaft 27, a second connecting shaft 26, two first conveyor belts 21, and two second conveyor belts 22. The two ends of the first connecting shaft 27 and the second connecting shaft 26 are rotatably connected to a first vertical plate 31 and a second vertical plate 32, respectively. The two first conveyor belts 21 and the two second conveyor belts 22 are arranged side-by-side along a first direction, which is parallel to the conveying direction F of the conveying module 20. Both the first conveyor belts 21 and the second conveyor belts 22 are suspended within the housing 10, reciprocating along a second direction via two guide rods 23, which is perpendicular to the conveying direction F of the conveying module 20. This design avoids the first conveyor belts 21 and 22 from contacting the inner wall of the housing 10, thus preventing them from affecting their movement and the conveying of the circuit board.

[0025] Two first conveyor belts 21 are configured to support opposite sides of the bottom surface of the circuit board. A first conveyor motor 271 is located on the outside of the first vertical plate 31. Specifically, the first conveyor motor 271 can be fixed to the outer wall of the first vertical plate 31 or the inner wall of the housing 10 by fasteners. The first conveyor motor 271 drives the two first conveyor belts 21 to convey the circuit board along the conveying direction F through the first connecting shaft 27.

[0026] Two second conveyor belts 22 are configured to support opposite sides of the bottom surface of the circuit board. A second conveyor motor 261 is located on the outside of the first vertical plate 31. Specifically, the second conveyor motor 261 can be fixed to the outer wall of the first vertical plate 31 or the inner wall of the housing 10 by fasteners. The second conveyor motor 261 drives the two second conveyor belts 22 to convey the circuit board along the conveying direction F through the second linkage shaft 26.

[0027] In this context, the conveying direction F should be understood as the first conveyor belt 21 and the second conveyor belt 22 conveying materials in the forward and reverse directions along the conveying direction F. The forward and reverse conveying process of the first conveyor belt 21 along the conveying direction F is achieved by the forward and reverse rotation of the first conveyor motor 271. Similarly, the forward and reverse conveying process of the second conveyor belt 22 along the conveying direction F is achieved by the forward and reverse rotation of the second conveyor motor 261. The forward and reverse rotation processes of the first conveyor motor 261 and the second conveyor motor 271 are controlled by a software program.

[0028] One of the two first conveyor belts 21 is threadedly connected to the first lead screw shaft 24. When the first lead screw motor 241 drives the first lead screw shaft 24 to rotate forward and backward, the first lead screw shaft 24 drives the corresponding first conveyor belt 21 to move, thereby adjusting the distance between the two first conveyor belts 21 so that the two first conveyor belts 21 are suitable for conveying circuit boards of different widths. One of the two second conveyor belts 22 is threadedly connected to the second lead screw shaft 25. The second lead screw shaft 25 drives the corresponding second conveyor belt 22 to move, thereby adjusting the distance between the two second conveyor belts 22 so that the two second conveyor belts 22 are suitable for conveying circuit boards of different widths.

[0029] Compared with the prior art, the housing 10 of this embodiment can protect the first conveyor belt 21, the second conveyor belt 22, the guide rod 23, the first lead screw shaft 24, the second lead screw shaft 25, the first connecting shaft 27, the second connecting shaft 26, the first lead screw motor 241, the second lead screw motor 251, the first conveyor motor 271, and the second conveyor motor 261.

[0030] Furthermore, compared with the prior art, in this embodiment, the guide rod 23, the first lead screw shaft 24, the second lead screw shaft 25, the first connecting shaft 27, and the second connecting shaft 26 are arranged side by side along the first direction. The first transmission belt 21 and the second transmission belt 22 can be suspended in the housing 10 and located between the first vertical plate 31 and the second vertical plate 32. The first lead screw motor 241, the second lead screw motor 251, the first conveyor motor 271, and the second conveyor motor 261 are arranged independently on the outside of the first vertical plate 31, which provides sufficient space between the first vertical plate 31 and the second vertical plate 32 for the first transmission belt 21 and the second transmission belt 22 to move. This makes the overall structure neater and simpler, and the subsequent maintenance process of the equipment is more convenient.

[0031] In some embodiments, two first lead screw shafts 24 are configured, arranged side by side; each first lead screw shaft 24 is fitted with a first synchronous pulley, and the first synchronous pulleys on the two first lead screw shafts 24 are connected by a first synchronous toothed belt 242. The output shaft of the first lead screw motor 241 is connected to one of the two first lead screw shafts 24. Both second transmission belts 22 have first clearance holes to avoid obstructing the two first lead screw shafts 24.

[0032] When the first lead screw motor 241 drives one of the first lead screw shafts 24 to rotate, the first lead screw shaft 24 drives the other first lead screw shaft 24 to rotate through two first synchronous pulleys and a first synchronous toothed belt 242, so that the two first lead screw shafts 24 can rotate synchronously, thereby synchronously driving the first transmission belt 21 to slide back and forth along the axial direction of the guide rod 23, making the sliding process of the first transmission belt 21 more stable.

[0033] Furthermore, there are two second lead screw shafts 25 arranged side by side; each second lead screw shaft 25 is fitted with a second synchronous pulley, and the two second synchronous pulleys on the two second lead screw shafts 25 are connected by a second synchronous toothed belt 252; the output shaft of the second lead screw motor 251 is connected to one of the two second lead screw shafts 25. Second clearance holes are provided on both first transmission belts 21 to avoid obstructing the two second lead screw shafts 25.

[0034] When the second lead screw motor 251 drives one of the second lead screw shafts 25 to rotate, the second lead screw shaft 25 drives the other second lead screw shaft 25 to rotate through two second synchronous pulleys and a second synchronous toothed belt 252, so that the two second lead screw shafts 25 can rotate synchronously, thereby synchronously driving the second transmission belt 22 to slide back and forth along the axial direction of the guide rod 23, making the sliding process of the second transmission belt 22 more stable.

[0035] In some embodiments, the first synchronous pulley, the first synchronous toothed belt 242, the second synchronous pulley, and the second synchronous toothed belt 252 are all located outside the second vertical plate 32. This can prevent the first synchronous pulley, the first synchronous toothed belt 242, the second synchronous pulley, and the second synchronous toothed belt 252 from interfering with the sliding process of the first transmission belt 21 or the second transmission belt 22 along the guide rod 23. In addition, it can make the structure between the first vertical plate 31 and the second vertical plate 32 more neat and simple.

[0036] In some embodiments, the housing 10 is provided with a first cabinet door 12, which is opposite to the first vertical plate 31. When it is necessary to install, inspect, maintain, or replace the first lead screw motor 241, the second lead screw motor 251, the first conveyor motor 271, and the second conveyor motor 261, simply open the first cabinet door 12 to perform the corresponding operations on the aforementioned components. During the operation, the first conveyor belt 21 and the second conveyor belt 22 between the first vertical plate 31 and the second vertical plate 32 will not come into contact, thus avoiding contact with the first conveyor belt 21 and the second conveyor belt 22 and causing the positions of the first conveyor belt 21 and the second conveyor belt 22 to shift, thereby preventing deviations in the distance between the two first conveyor belts 21 and the two second conveyor belts 22.

[0037] Furthermore, the housing 10 also has a second cabinet door 13, which is opposite to the second vertical plate 32. When it is necessary to install, inspect, maintain, or replace the first synchronous pulley, the second synchronous pulley, the first synchronous toothed belt 242, and the second synchronous toothed belt 252, simply open the second cabinet door 13 to perform the corresponding operations on the aforementioned components. During the operation, the first transmission belt 21 and the second transmission belt 22 between the first vertical plate 31 and the second vertical plate 32 will not come into contact, thus avoiding contact with the first transmission belt 21 and the second transmission belt 22 and causing their positions to shift, thereby preventing deviations in the distance between the two first transmission belts 21 and the two second transmission belts 22.

[0038] In some embodiments, the housing 10 includes an upper cavity and a lower cavity; a first conveyor belt 21 and a second conveyor belt 22 are located in the upper cavity. A first synchronous pulley, a first synchronous toothed belt 242, a second synchronous pulley, a second synchronous toothed belt 252, a first conveyor motor 271, a second conveyor motor 261, a first lead screw motor 241, and a second lead screw motor 251 are located in the lower cavity. A first cabinet door 12 and a second cabinet door 13 are opened in the lower cavity. This makes the positions of the first conveyor belt 21 and the second conveyor belt 22 independent of the positions of the first synchronous pulley, the first synchronous toothed belt 242, the second synchronous pulley, the second synchronous toothed belt 252, the first conveyor motor 271, the second conveyor motor 261, the first lead screw motor 241, and the second lead screw motor 251.

[0039] In some embodiments, the upper cavity is provided with a third cabinet door 14. When it is necessary to install, inspect, maintain, or replace the first conveyor belt 21 and the second conveyor belt 22, the aforementioned operations can be completed simply by opening the third cabinet door 14, making the operation relatively simple.

[0040] In some embodiments, a feed window 15 and a discharge window 16 are respectively provided on opposite sides of the upper cavity. The two ends of the first conveyor belt 21 are exposed outside the feed window 15 and the discharge window 16, respectively, and the two ends of the second conveyor belt 22 are exposed outside the feed window 15 and the discharge window 16, respectively. This structure facilitates the docking of the first conveyor belt 21 and the second conveyor belt 22 with external equipment (such as transplanting equipment).

[0041] In some embodiments, the first conveyor belt 21 includes a first support plate, a first conveyor belt, a first driving pulley, and a plurality of first driven pulleys. The first support plate is threadedly connected to the first lead screw shaft 24 and is sleeved on the guide rod 23, allowing it to slide relative to the guide rod 23. The first driving pulley and the plurality of first driven pulleys are rotatably mounted on the first support plate. The first conveyor belt is sleeved on the first driving pulley and the plurality of first driven pulleys. The first connecting shaft 27 is prismatic in shape, and the shaft of the first driving pulley is a hollow tube. The inner cavity shape of the hollow tube is adapted to the shape of the first connecting shaft 27. The hollow tube is sleeved on the first connecting shaft 27. When the first connecting shaft 27 rotates, it can drive the hollow tube to rotate synchronously. The hollow tube drives the first driving pulley to rotate, and the first driving pulley can drive the first conveyor belt and the plurality of first driven pulleys to rotate. The circuit board is supported and conveyed by the first conveyor belt.

[0042] The second transmission belt 22 includes a second support plate, a second transmission belt, a second driving pulley, and multiple second driven pulleys. The surface of the second support plate is parallel to the surface of the first support plate. The second support plate is threadedly connected to the second lead screw shaft 25 and is sleeved on the guide rod 23, allowing it to slide relative to the guide rod 23. The second driving pulley and multiple second driven pulleys are rotatably mounted on the second support plate; the second transmission belt is sleeved on the second driving pulley and multiple second driven pulleys; the second connecting shaft 26 is prismatic in shape, and the shaft of the second driving pulley is a hollow tube. The inner shape of the hollow tube is adapted to the shape of the second connecting shaft 26, and the hollow tube is sleeved on the second connecting shaft 26. Specifically, the structure of the second transmission belt 22 is similar to that of the first transmission belt 21, and the connection relationship of the components of the second transmission belt 22 will not be described in detail here.

[0043] In some embodiments, the dual-track connecting platform further includes a first feed sensor 41, a second feed sensor, a first discharge sensor 42, a second discharge sensor, and a control unit 11. The control unit 11 may be a PLC controller, an industrial computer, or other common controllers. The first feed sensor 41 is located between the feed ends of the two first conveyor belts 21. The first discharge sensor 42 is located between the discharge ends of the two first conveyor belts 21. When the circuit board is conveyed to the feed end of the first conveyor belt 21, the first feed sensor 41 can sense the feed signal and feed the signal back to the control unit 11. The control unit 11 controls the first conveying mechanism to drive the first conveyor belt 21 to convey the circuit board. When the circuit board is conveyed to the discharge end of the first conveyor belt 21, the first discharge sensor 42 senses the circuit board and generates a discharge signal, which is then fed back to the control unit 11. The control unit 11 controls the first conveying mechanism to stop driving the second conveyor belt 22, waiting for the next process equipment to send a feeding signal to the control unit 11. Then, the control unit 11 controls the first conveying mechanism to drive the second conveyor belt 22 to convey the circuit board to the next process equipment. This approach allows the dual-track connecting platform of this embodiment to better adapt to the processing rhythm of the preceding and following process equipment.

[0044] The second feed sensor is located between the feed ends of the two second conveyor belts 22, and the second discharge sensor is located between the discharge ends of the two second conveyor belts 22. The first feed sensor 41, the first discharge sensor 42, the second feed sensor, the second discharge sensor, the first conveying drive mechanism, the second conveying drive mechanism, the first lead screw motor 241, and the second lead screw motor 251 are all electrically connected to the control unit 11. The working logic of the second feed sensor and the second discharge sensor is the same as that of the first feed sensor 41 and the first discharge sensor 42. Therefore, the working logic of the second feed sensor and the second discharge sensor will not be described in detail here.

[0045] In some embodiments, the first feed sensor 41, the second feed sensor, the first discharge sensor 42, and the second discharge sensor are all slidably connected to the frame. Specifically, the inner wall of the housing 10 is provided with four guide rails, and the first feed sensor 41, the second feed sensor, the first discharge sensor 42, and the second discharge sensor are respectively slidably connected to the four guide rails. The sliding directions of the first feed sensor 41 and the first discharge sensor 42 are both perpendicular to the conveying direction F of the first conveying module 20; the sliding directions of the second feed sensor and the second discharge sensor are both perpendicular to the conveying direction F of the second conveying module 20. By manually sliding the first feed sensor 41, the second feed sensor, the first discharge sensor 42, and the second discharge sensor, their positions can be changed, allowing them to adapt to sensing circuit boards of different widths.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
