Description

Technical Field

[0001] This application relates to the field of circuit board transportation technology, and in particular to a transportation device and production line. Background Technology

[0002] During the production process, PCBs (Printed Circuit Boards) typically require transportation and transfer to undergo various processing steps. In related technologies, conveyor belts are commonly used to transport PCBs. This involves setting up two conveyor belts, one carrying one end of the PCB and the other carrying the other. The synchronous rotation of the two conveyor belts drives the movement of the PCB.

[0003] During the implementation of this application embodiment, the inventors discovered that in related technologies, the distance between the two conveyor belts of the transport equipment is difficult to adjust, which limits the size of the PCB boards that the transport equipment can transport. Summary of the Invention

[0004] The main technical problem solved by the embodiments of this application is to provide a transportation equipment and production line that can adjust the distance between conveyor belts according to PCB boards of different sizes, thereby expanding the application range of the transportation equipment.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a transportation device, including a mounting frame; a first upright, disposed on the mounting frame; a second upright, including a first guide rail, a first slider, a first connecting frame, a first mounting plate, a locking member, and a screw connector, wherein the first guide rail is disposed on the mounting frame, the first slider is slidably disposed on the first guide rail, and the first slider can slide relative to the first guide rail along a first direction, the first direction being parallel to the arrangement direction of the first upright and the second upright; the first connecting frame is disposed on the first slider, and the first mounting plate is disposed on the first connecting frame; the locking member is disposed on the mounting frame, the locking member having a first through hole, the screw connector passing through the first through hole, and the screw connector being screwed and fixed to the first connecting frame. In a first direction, the size of the first through hole is larger than the nominal diameter of the screw connector; a first drive module is mounted on the mounting bracket; a first drive wheel is rotatably mounted on one end of the first upright, and the first drive wheel is connected to the first drive module; a first driven wheel is rotatably mounted on the first upright, and the first drive wheel and the first driven wheel are respectively located at both ends of the first upright; a first conveyor belt is sleeved on the first drive wheel and the first driven wheel; a second drive wheel is rotatably mounted on one end of the first mounting plate, and the second drive wheel is connected to the first drive module; a second driven wheel is rotatably mounted on the first mounting plate, and the second driven wheel and the second drive wheel are respectively located at both ends of the first mounting plate; a second conveyor belt is sleeved on the second drive wheel and the second driven wheel.

The carrier includes a first part and a second part. The first part is provided with a receiving groove, and the second part is removably covered by the receiving groove. The receiving groove is used to receive a PCB board. In a first direction, the size of the first part is larger than the size of the second part. In a second direction, a third conveyor belt and a fifth conveyor belt are spaced apart from each other, and a fourth conveyor belt and a sixth conveyor belt are spaced apart from each other. In the first direction, the distance between the third conveyor belt and the fourth conveyor belt is greater than the distance between the fifth conveyor belt and the sixth conveyor belt. The third conveyor belt and the fourth conveyor belt are used together to transport the first part, and the fifth conveyor belt and the sixth conveyor belt are used together to transport the second part.

[0013] In some embodiments, the transport equipment further includes a material unloading module, which includes a fifth upright, a sixth upright, a fourth drive module, a seventh drive wheel, a seventh driven wheel, a seventh conveyor belt, an eighth drive wheel, an eighth driven wheel, and an eighth conveyor belt.

The seventh conveyor belt and the eighth conveyor belt are used together to transport PCB boards.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in the embodiments of this application is to provide a production line, including the above-mentioned transportation equipment.

[0015] The beneficial effects of this application embodiment are as follows: Unlike the prior art, in this application embodiment, by rotatably setting the first drive wheel and the first driven wheel at both ends of the first upright, and by sleeved the first conveyor belt on the first drive wheel and the first driven wheel, and rotatably setting the second drive wheel and the second driven wheel at both ends of the first mounting plate, and by sleeved the second conveyor belt on the second drive wheel and the second driven wheel, the first drive wheel and the second drive wheel are driven to rotate by the first drive module, thereby driving the first conveyor belt and the second conveyor belt to move.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The transport equipment 100 includes a mounting frame 11, a first upright frame 12, a second upright frame 13, a first drive module 14, a first drive wheel 15, a first driven wheel 16, a first conveyor belt 17, a second drive wheel 18, a second driven wheel 19, and a second conveyor belt 20. The mounting frame 11 forms the main frame structure of the transport equipment 100. The mounting frame 11 is generally frame-shaped and is used to support and install the various components of the transport equipment 100, providing a stable mounting foundation for each component. The first upright frame 12 is mounted on the mounting frame 11. The first upright frame 12 is generally plate-shaped or frame-shaped and extends along the transport direction, supporting the first drive wheel 15 and the first driven wheel 16.

[0023] The second support frame 13 includes a first guide rail 131, a first slider 132, a first connecting frame 133, a first mounting plate 134, a locking element 135, and a screw connector 136. The first guide rail 131 is disposed on the mounting frame 11 and extends along a first direction X. The first direction X is parallel to the arrangement direction of the first support frame 12 and the second support frame 13, i.e., the first direction X is perpendicular to the transport direction of the PCB board 200. The first slider 132 is slidably disposed on the first guide rail 131. The first slider 132 has a groove inside that matches the first guide rail 131. The first slider 132 can slide relative to the first guide rail 131 along the first direction X, thereby realizing the position adjustment of the second support frame 13 relative to the mounting frame 11. The first connecting frame 133 is disposed on the first slider 132. The first connecting frame 133 has a plate-like or frame-like structure and is used to connect the first slider 132 and the first mounting plate 134, serving as a connecting element. The first mounting plate 134 is disposed on the first connecting frame 133. The first mounting plate 134 has an overall plate-like structure and extends along the transport direction to support the second drive wheel 18 and the second driven wheel 19.

[0024] A locking member 135 is disposed on the mounting bracket 11. The locking member 135 has a plate-like structure and a first through hole 1351, which extends in a long strip along the first direction X. A screw connector 136 passes through the first through hole 1351 and is screwed to the first connecting bracket 133 for fixation. The screw connector 136 can be a bolt or a screw. In the first direction X, the size of the first through hole 1351 is larger than the nominal diameter of the screw connector 136, so that the screw connector 136 can move within the first through hole 1351 along the first direction X within a certain range. Therefore, when adjusting the position of the second stand 13, the screw connector 136 will not obstruct the movement of the second stand 13. After the adjustment is completed, by tightening the screw connector 136, the head of the screw connector 136 presses against the locking member 135, which can fix the first connecting frame 133 to the locking member 135, thereby fixing the second stand 13 to the mounting bracket 11.

[0025] The first drive module 14 is mounted on the mounting frame 11 and provides driving force to drive the conveyor belt. The first drive wheel 15 is rotatably mounted at one end of the first upright 12 and is connected to the first drive module 14, allowing the first drive module 14 to drive the first drive wheel 15 to rotate. The first driven wheel 16 is rotatably mounted on the first upright 12, with the first drive wheel 15 and the first driven wheel 16 located at opposite ends of the first upright 12, maintaining a certain distance between them to tension the first conveyor belt 17. The first conveyor belt 17 is fitted onto the first drive wheel 15 and the first driven wheel 16, and is circular. When the first drive wheel 15 rotates, it drives the first conveyor belt 17 to move, which in turn drives the first driven wheel 16 to rotate.

[0026] The second drive wheel 18 is rotatably mounted on one end of the first mounting plate 134. The second drive wheel 18 is connected to the first drive module 14, which can simultaneously drive the first drive wheel 15 and the second drive wheel 18 to rotate. The second driven wheel 19 is rotatably mounted on the first mounting plate 134, and the second driven wheel 19 and the second drive wheel 18 are located at opposite ends of the first mounting plate 134, with a certain distance between them to tension the second conveyor belt 20. The second conveyor belt 20 is sleeved on the second drive wheel 18 and the second driven wheel 19. The second conveyor belt 20 is annular. When the second drive wheel 18 rotates, it drives the second conveyor belt 20 to move, which in turn drives the second driven wheel 19 to rotate.

[0027] During operation, the PCB board 200 is placed on the first conveyor belt 17 and the second conveyor belt 20. The first conveyor belt 17 carries one end of the PCB board 200, and the second conveyor belt 20 carries the other end of the PCB board 200. The first drive module 14 drives the first drive wheel 15 and the second drive wheel 18 to rotate, thereby driving the first conveyor belt 17 and the second conveyor belt 20 to move synchronously. The first conveyor belt 17 and the second conveyor belt 20 together carry the PCB board 200 and drive the PCB board 200 to move along the transport direction, realizing the transfer of the PCB board 200 to different workstations.

[0028] By setting the first mounting plate 134 on the first connecting frame 133, setting the first connecting frame 133 on the first slider 132, and sliding the first slider 132 on the first guide rail 131, the distance between the first mounting plate 134 and the first stand 12 can be adjusted. When it is necessary to transport PCB boards 200 of different sizes, by loosening the screw connector 136, the first slider 132 can slide along the first guide rail 131, thereby adjusting the distance between the first mounting plate 134 and the first stand 12, and thus adjusting the distance between the first conveyor belt 17 and the second conveyor belt 20; after adjustment, the second stand 13 is fixed by tightening the screw connector 136. Since the size of the first through hole 1351 is larger than the nominal diameter of the screw connector 136, the screw connector 136 can move freely within the first through hole 1351 during adjustment, which helps to improve the smoothness of the adjustment process. After adjustment, the screw connector 136 is screwed and fixed to the first connecting frame 133, and the locking member 135 is pressed by the head of the screw connector 136, thereby firmly fixing the second stand 13 to the mounting frame 11, which helps to improve the stability of the second stand 13 during operation. With the above structure, the transport equipment 100 can be used to transport PCB boards 200 of various sizes without replacing equipment or making major modifications, which helps to reduce production costs, shorten equipment debugging time, and expand the application range of the transport equipment 100.

[0029] It is worth noting that in some cases, the first conveyor belt 17 and the second conveyor belt 20 need to move synchronously to keep the PCB board 200 stable during transportation and reduce the risk of the PCB board 200 tilting or falling. Additionally, since the position of the first mounting plate 134 is adjustable, the second drive wheel 18 moves along the first direction X with the first mounting plate 134. After adjusting the position of the first mounting plate 134, the position of the second drive wheel 18 along the axial direction of the drive shaft 142 needs to be restricted to ensure that the second drive wheel 18 can stably drive the second conveyor belt 20, reducing the risk of axial movement of the second drive wheel 18 during rotation.

[0030] Please see Figure 2 and Figure 3In some embodiments, the first drive module 14 includes a first motor 141, a drive shaft 142, and two limiting rings 143. The first motor 141 is mounted on the mounting bracket 11 and serves as a power source to provide rotational driving force. The first motor 141 can be a servo motor or a stepper motor. The drive shaft 142 extends along a first direction X and passes through a first mounting plate 134. The drive shaft 142 is rotatable relative to the first mounting plate 134, and a bearing is provided on the first mounting plate 134 to support the drive shaft 142. The first drive wheel 15 and the second drive wheel 18 are both sleeved on the drive shaft 142, and both the first drive wheel 15 and the second drive wheel 18 are circumferentially fixed to the drive shaft 142. Circumferential fixation can be achieved through keyed or splined connections. When the drive shaft 142 rotates, the first drive wheel 15 and the second drive wheel 18 rotate synchronously. The output shaft of the first motor 141 is connected to the drive shaft 142 via a coupling, or via a belt pulley or gear transmission. The first motor 141 can drive the drive shaft 142 to rotate via the output shaft.

[0031] Both limiting rings 143 are sleeved on the drive shaft 142. One limiting ring 143 abuts against the side of the first mounting plate 134 opposite to the second drive wheel 18, and the other limiting ring 143 abuts against the side of the second drive wheel 18 opposite to the first mounting plate 134. The two limiting rings 143 can move along the axial direction of the drive shaft 142. After the position of the first mounting plate 134 is adjusted into place, the two limiting rings 143 can be locked so that they abut against the first mounting plate 134 and the second drive wheel 18 respectively, thereby restricting the movement of the second drive wheel 18 along the axial direction of the drive shaft 142. The first motor 141 and the drive shaft 142 simultaneously drive the first drive wheel 15 and the second drive wheel 18 to rotate. Since both the first drive wheel 15 and the second drive wheel 18 are mounted on the same drive shaft 142, they can rotate synchronously at the same speed. This improves the consistency of the movement speed between the first conveyor belt 17 and the second conveyor belt 20, allowing the PCB board 200 to maintain a stable posture during transportation and reducing the risk of the PCB board 200 tilting or falling. Furthermore, the two limiting rings 143 limit the second drive wheel 18 in the axial direction, restricting its movement along the drive shaft 142. This improves the stability of the second drive wheel 18 during operation, reduces the risk of the second conveyor belt 20 deviating due to the movement of the second drive wheel 18, and thus enhances the stability and reliability of the second conveyor belt 20's movement.

[0032] It is worth noting that the limiting ring 143 needs to be able to move freely along the axial direction on the drive shaft 142 so that after adjusting the position of the first mounting plate 134, the limiting ring 143 can be moved to a suitable position. At the same time, the limiting ring 143 also needs to be able to be securely fixed to the drive shaft 142 in a suitable position to achieve reliable limiting of the second drive wheel 18. Therefore, a limiting ring 143 with a simple structure and convenient operation is needed to meet the above-mentioned requirements for movement and fixation.

[0033] Please see Figure 3 and Figure 4 In some embodiments, the limiting ring 143 includes a ring body 1431 and a screw 1432. The ring body 1431 is generally ring-shaped and is sleeved on the drive shaft 142. The inner diameter of the ring body 1431 is slightly larger than the outer diameter of the drive shaft 142, allowing the ring body 1431 to slide along the axial direction of the drive shaft 142. The ring body 1431 is provided with a notch 1433 and a screw hole 1434. The notch 1433 penetrates the outer and inner circumferential surfaces of the ring body 1431 in the radial direction, forming an open ring structure. The screw hole 1434 penetrates the notch 1433, meaning that the axis of the screw hole 1434 is perpendicular to the extension direction of the notch 1433. The screw 1432 is screwed into the screw hole 1434, with the threaded portion of the screw 1432 passing through the screw hole 1434.

[0034] When screw 1432 is tightened, the threaded portion of screw 1432 screws into the threaded hole 1434. Screw 1432 presses against the two side walls of notch 1433, causing notch 1433 to gradually close. The material on both sides of notch 1433 moves closer to each other, and the inner diameter of ring 1431 gradually decreases. This causes the inner wall of ring 1431 to tightly grip the outer wall of drive shaft 142, thus fixing the limiting ring 143 to drive shaft 142. When it is necessary to adjust the position of limiting ring 143, screw 1432 is loosened. Notch 1433 opens under the elastic restoring force of the material of ring 1431, the inner diameter of ring 1431 increases, the friction between ring 1431 and drive shaft 142 decreases, and limiting ring 143 can move freely along the axial direction of drive shaft 142. With the above structure, the limiting ring 143 can be easily adjusted and fixed on the drive shaft 142 without the need for special tools; only a screwdriver is required. This simple and quick operation improves adjustment efficiency and shortens equipment debugging time. Furthermore, the simple structure and few parts of the limiting ring 143 help reduce manufacturing and maintenance costs.

[0035] It is worth noting that when processing PCB board 200, it is usually necessary to remove it from the conveyor belt and transfer it to the processing station. In related technologies, if a robotic arm needs to grasp the PCB board 200 from the conveyor belt, the conveyor belt usually needs to be stopped until the robotic arm completes the grasp before resuming operation. However, stopping the conveyor belt affects transport efficiency and increases production cycle time. In addition, frequent start-stop of the conveyor belt increases the load on the drive motor, shortens the motor's lifespan, and increases equipment maintenance costs.

[0036] Please see Figure 1 and Figure 2 In some embodiments, the transport device 100 further includes a lifting module 22. The lifting module 22 includes a lifting cylinder 221 and a top plate 222. The lifting cylinder 221 is disposed on the mounting frame 11, located below the first conveyor belt 17 and the second conveyor belt 20. The lifting cylinder 221 provides linear driving force and can be a single-acting or double-acting cylinder. The top plate 222 is disposed at the output end of the lifting cylinder 221, i.e., the top plate 222 is connected to the piston rod of the lifting cylinder 221. The top plate 222 has a plate-like structure, and its upper surface is flat, used to support the PCB board 200. The lifting cylinder 221 drives the top plate 222 to move along a second direction Y, which is perpendicular to the first direction X. In the illustrated orientation, the second direction Y is vertical, meaning the top plate 222 can move up and down.

[0037] During operation, when the first conveyor belt 17 and the second conveyor belt 20 transport the PCB board 200 to the first preset position, the lifting cylinder 221 drives the top plate 222 to move upward along the second direction Y. The top plate 222 rises through the gap between the first conveyor belt 17 and the second conveyor belt 20, and the upper surface of the top plate 222 contacts the bottom surface of the PCB board 200. It continues to rise, lifting the PCB board 200 from the first preset position to the second preset position, thus separating the PCB board 200 from the first conveyor belt 17 and the second conveyor belt 20. After the PCB board 200 is separated from the conveyor belts, it is stably supported by the top plate 222 and no longer moves with the conveyor belts. The robot arm can easily grasp the PCB board 200 without stopping the first conveyor belt 17 and the second conveyor belt 20. By lifting the PCB board 200 and separating it from the conveyor belts through the lifting module 22, the first conveyor belt 17 and the second conveyor belt 20 can continue to operate, which helps to improve transportation efficiency and shorten production cycle time. Meanwhile, since the conveyor belt does not need to be frequently started and stopped, it helps to reduce the load on the drive motor, extend the motor's service life, and reduce equipment maintenance costs. In addition, after the top plate 222 lifts the PCB board 200, the PCB board 200 is in a stable stationary state, which helps to improve the positioning accuracy of the robot arm when grasping the PCB board 200 and reduce the risk of grasping failure.

[0038] In some embodiments, there are two lifting modules 22, one of which is located on the side of the first support 12 away from the second support 13, and the other is located on the side of the second support 13 away from the first support 12. With this arrangement, the two lifting modules 22 can lift the PCB board from both ends of the PCB board 200 respectively, which helps to improve the stability during the process of lifting the PCB board.

[0039] It is worth noting that the top plate 222 can only accurately lift the PCB board 200 when the PCB board 200 is in a specific position (i.e., the first preset position). If the PCB board 200 has not reached the first preset position or has passed the first preset position, the top plate 222 may not be able to make proper contact with the PCB board 200 after rising, resulting in lifting failure. Therefore, a mechanism is needed to ensure that the PCB board 200 can accurately stay in the first preset position so that the top plate 222 can accurately lift the PCB board 200.

[0040] In some embodiments, please refer to Figure 2 and Figure 3 The transport equipment 100 also includes a baffle module 21. The baffle module 21 includes a blocking cylinder 211 and a blocking block 212. The blocking cylinder 211 is mounted on the mounting frame 11 and located between the first conveyor belt 17 and the second conveyor belt 20. The blocking cylinder 211 provides linear driving force. The blocking block 212 is located at the output end of the blocking cylinder 211, i.e., the blocking block 212 is connected to the piston rod of the blocking cylinder 211. The blocking block 212 has a block-like structure and can be made of metal or engineering plastic. Viewed along the second direction Y, the blocking block 212 is located in the gap between the first conveyor belt 17 and the second conveyor belt 20. The blocking cylinder 211 is configured to drive the blocking block 212 to move along the second direction Y, i.e., the blocking block 212 can move up and down.

[0041] When the blocking block 212 moves to the third preset position, in the second direction Y, the blocking block 212 at least partially protrudes from the top of the first conveyor belt 17, that is, the top of the blocking block 212 is higher than the upper surface of the first conveyor belt 17. When the PCB board 200 moves to the third preset position under the drive of the first conveyor belt 17 and the second conveyor belt 20, the front end of the PCB board 200 abuts against the part of the blocking block 212 protruding from the first conveyor belt 17. The blocking block 212 prevents the PCB board 200 from continuing to move forward, so that the PCB board 200 can accurately stop at the first preset position, which facilitates the top plate 222 to lift the PCB board 200. After the top plate 222 lifts the PCB board 200, the gripping module 23 grips the PCB board 200; after the PCB board 200 is gripped, the blocking cylinder 211 drives the blocking block 212 to move downward below the upper surface of the first conveyor belt 17, and the blocking block 212 no longer protrudes from the conveyor belt surface, so that the subsequent PCB board 200 can continue to move forward. The baffle module 21 ensures that the PCB board 200 accurately stops at the first preset position, which helps improve the success rate of the top plate 222 lifting the PCB board 200 and reduces the risk of lifting failure due to the positional deviation of the PCB board 200. In addition, the blocking cylinder 211 drives the blocking block 212 to rise and fall, which can realize the automatic control of the blocking block 212 without manual intervention, thus facilitating the automation of the production process.

[0042] It is worth noting that after the PCB board 200 is lifted by the top plate 222, it needs to be transferred to the processing station for processing. Relying solely on manual handling is inefficient and easily damages the PCB board 200; placing the processing equipment directly above the lifting position limits the flexibility of its layout. Therefore, a gripping module 23 and a feeding module 24 are required to automate the transfer of the PCB board 200 from the lifting position to the processing station.

[0043] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the transport device 100 further includes a gripping module 23 and a feeding module 24. Both the gripping module 23 and the feeding module 24 are connected to the mounting frame 11. The gripping module 23 is used to grip the PCB board 200 located at a second preset position and transfer it to the feeding module 24, and the feeding module 24 is used to transport the PCB board 200 to the processing station.

[0044] By cooperating with the gripping module 23 and the feeding module 24, the PCB board 200 can be automatically transferred from the top plate 222 to the processing station. Specifically, after the top plate 222 lifts the PCB board 200 to the second preset position, the gripping module 23 grips the PCB board 200 and places it on the feeding module 24, which then transports the PCB board 200 to the processing station. In this way, the transfer process of the PCB board 200 does not require manual intervention, which helps improve production efficiency and reduce labor costs. At the same time, automated transfer reduces the risk of damage to the PCB board 200 during manual handling, thus improving product yield. Furthermore, by using the feeding module 24 to transport the PCB board 200 to the processing station, the placement of the processing equipment is no longer limited by the lifting position, which improves the flexibility of the processing equipment layout and optimizes the production line layout.

[0045] In some embodiments, the gripping module 23 can be a robotic arm, which includes multiple joints and an end effector, such as a suction cup or a gripper. The robotic arm can flexibly grip the PCB board 200 and place it on the feeding module 24. The robotic arm can be a three-axis, four-axis, or six-axis robotic arm, and the appropriate type of robotic arm can be selected according to actual needs.

[0046] In some embodiments, please refer to Figure 5 and Figure 6The feeding module 24 includes a mounting base plate 241, a movable frame 242, a first drive assembly 243, a second drive assembly 244, and a support frame 245. The mounting base plate 241 is mounted on the mounting frame 11 and has an overall plate-like structure, used to support the movable frame 242 and the first drive assembly 243. The first drive assembly 243 is mounted on the mounting base plate 241 and consists of a first drive motor 2431 and a first lead screw 2432. The first lead screw 2432 extends along a first direction X, with one end connected to the output shaft of the first drive motor 2431 and the other end supported on the mounting base plate 241 by a bearing. The movable frame 242 is threadedly connected to the first lead screw 2432, and a nut 2421 matching the first lead screw 2432 is provided on the movable frame 242. The first drive assembly 243 drives the movable frame 242 to move along the first direction X via the first lead screw 2432. The second drive assembly 244 is disposed on the movable frame 242 and is used to drive the carrier frame 245 to move up and down along the second direction Y. The gripping module 23 is used to grip the PCB board 200 and place the PCB board 200 on the carrier frame 245. Then, the second drive assembly 244 drives the carrier frame 245 to move along the second direction Y to a suitable height position. Then, the first drive assembly 243 drives the carrier frame 245 to move along the first direction X, moving the PCB board 200 to the processing station. Through the cooperation of the first drive assembly 243 and the second drive assembly 244, the carrier frame 245 can move freely in the plane formed by the first direction X and the second direction Y, which helps to improve the movement flexibility of the feeding module 24 and adapt to the position requirements of different processing stations.

[0047] In some embodiments, the second drive assembly 244 includes a second drive motor 2441, a transmission belt 2442, and two second lead screws 2443. The two second lead screws 2443 are rotatably mounted on both sides of the movable frame 242, and both extend along the second direction Y. The two second lead screws 2443 are threadedly connected to both ends of the support frame 245, meaning that nuts matching the two second lead screws 2443 are respectively provided at both ends of the support frame 245. The second drive motor 2441 is mounted on the movable frame 242 and is drively connected to the two second lead screws 2443 via the transmission belt 2442. The transmission belt 2442 is sleeved on the output shaft of the second drive motor 2441 and the ends of the two second lead screws 2443, enabling the second drive motor 2441 to simultaneously drive the two second lead screws 2443 to rotate. The two second lead screws 2443 rotate synchronously, thereby driving the support frame 245 to move along the second direction Y. By connecting the two second lead screws 2443 to both ends of the support frame 245 respectively, the two ends of the support frame 245 can be raised and lowered synchronously, which helps to improve the stability and balance of the support frame 245 during movement and reduces the risk of the support frame 245 tilting due to unilateral drive.

[0048] It is worth noting that in some cases, the PCB board 200 needs to be processed using a carrier 300. The carrier 300 is a tooling used to support and secure the PCB board 200. Before loading, the PCB board 200 is placed in the receiving slot 3011 of the carrier 300, which positions and protects it. After processing, the PCB board 200 needs to be removed from the carrier 300 and transferred to the equipment used in the next process. The empty carrier 300 needs to be returned to the loading position for reuse. In related technologies, after processing, the empty carrier 300 needs to be manually collected and transported to the loading position, resulting in high labor costs and low manual handling efficiency, making it difficult to meet the demands of high-speed production.

[0049] In some embodiments, please refer to Figure 1 , Figure 7 and Figure 8 The transport equipment 100 also includes a return track 25. The return track 25 includes a third upright 251, a fourth upright 252, a second drive module 253, a third drive wheel 254, a third driven wheel 255, a third conveyor belt 256, a fourth drive wheel 257, a fourth driven wheel 258, and a fourth conveyor belt 259. The third upright 251 and the fourth upright 252 are spaced apart along a first direction X on the mounting frame 11, and the distance between the third upright 251 and the fourth upright 252 matches the width of the carrier 300. Both the third upright 251 and the fourth upright 252 have a plate-like or frame-like structure, and are used to support the third drive wheel 254, the third driven wheel 255, the fourth drive wheel 257, and the fourth driven wheel 258, respectively.

[0050] The third drive wheel 254 is rotatably mounted at one end of the third support frame 251, and the third driven wheel 255 is rotatably mounted at the other end of the third support frame 251. The third conveyor belt 256 is fitted onto the third drive wheel 254 and the third driven wheel 255, and the third conveyor belt 256 is annular. The fourth drive wheel 257 is rotatably mounted at one end of the fourth support frame 252, and the fourth driven wheel 258 is mounted at the other end of the fourth support frame 252. The fourth conveyor belt 259 is fitted onto the fourth drive wheel 257 and the fourth driven wheel 258, and the fourth conveyor belt 259 is annular. The second drive module 253 is mounted on the mounting frame 11. The third drive wheel 254 and the fourth drive wheel 257 are both connected to the second drive module 253. The second drive module 253 can simultaneously drive the third drive wheel 254 and the fourth drive wheel 257 to rotate, thereby causing the third conveyor belt 256 and the fourth conveyor belt 259 to move synchronously.

[0051] The return track 25 is configured to transport the carrier 300 used to load the PCB board 200. After processing, the PCB board 200 and carrier 300 are returned from the processing station to the working range of the gripping module 23 via the feeding module 24. Then, the gripping module 23 removes the PCB board 200 from the carrier 300 and transfers it to the unloading module 26 (i.e., the unloading track). The empty carrier 300 is then transferred to the return track 25 via the gripping module 23. The carrier 300 is placed on the third conveyor belt 256 and the fourth conveyor belt 259. The third conveyor belt 256 carries one end of the carrier 300, and the fourth conveyor belt 259 carries the other end. The second drive module 253 drives the third conveyor belt 256 and the fourth conveyor belt 259 to move synchronously, causing the carrier 300 to return to the loading position, thereby facilitating the centralized recycling and reuse of the carrier 300. By setting up the return track 25, the carrier 300 can automatically return to the loading position, eliminating the need for manual recycling and handling, which helps save labor costs and reduce labor intensity. At the same time, automatic return improves the turnover efficiency of the carrier 300 and shortens its return time, thus improving production cycle time and meeting the demands of high-cycle production. Furthermore, the return track 25 is integrated with other parts of the transport equipment 100, resulting in a compact overall structure that helps save floor space on the production line.

[0052] It is worth noting that, please refer to Figure 9 The carrier 300 typically consists of two parts: a first part 301 and a second part 302. The first part 301 is the main body of the carrier 300, equipped with a receiving slot 3011 for accommodating the PCB board 200. The second part 302 is the cover plate of the carrier 300, removably placed over the receiving slot 3011 to clamp and protect the PCB board 200. Since the first part 301 needs to have the receiving slot 3011 to accommodate the PCB board 200, while the second part 302 only needs to cover the opening of the receiving slot 3011, the dimensions of the first part 301 and the second part 302 are often different, with the first part 301 typically being larger than the second part 302. Using a single-pitch track makes it difficult to simultaneously recover the first part 301 and the second part 302, which have different dimensions. Setting up two separate return tracks would increase equipment costs and floor space.

[0053] Please see Figure 7 and Figure 8In some embodiments, the return track 25 further includes a third drive module 25a, a fifth drive wheel 25b, a fifth driven wheel 25c, a fifth conveyor belt 25d, a sixth drive wheel 25e, a sixth driven wheel 25f, and a sixth conveyor belt 25g. The fifth drive wheel 25b is rotatably mounted at one end of the third support frame 251, the fifth driven wheel 25c is rotatably mounted at the other end of the third support frame 251, and the fifth conveyor belt 25d is fitted over the fifth drive wheel 25b and the fifth driven wheel 25c, forming a ring. The sixth drive wheel 25e is rotatably mounted at one end of the fourth support frame 252, the sixth driven wheel 25f is rotatably mounted at the other end of the fourth support frame 252, and the sixth conveyor belt 25g is fitted over the sixth drive wheel 25e and the sixth driven wheel 25f, forming a ring. The third drive module 25a is mounted on the mounting bracket 11. The fifth drive wheel 25b and the sixth drive wheel 25e are both connected to the third drive module 25a for transmission. The third drive module 25a can simultaneously drive the fifth drive wheel 25b and the sixth drive wheel 25e to rotate, thereby causing the fifth conveyor belt 25d and the sixth conveyor belt 25g to move synchronously.

[0054] Please combine Figure 7 , Figure 8 and Figure 9 The carrier 300 includes a first part 301 and a second part 302. The first part 301 is provided with a receiving groove 3011, which is a recessed area on the upper surface of the first part 301. The shape and size of the receiving groove 3011 match the PCB board 200, and the receiving groove 3011 is used to receive the PCB board 200. The second part 302 is removably disposed on the receiving groove 3011. The second part 302 has a plate-like structure, and its shape and size match the opening of the receiving groove 3011. The second part 302 is used to cover the receiving groove 3011 and press the PCB board 200. In the first direction X, the size of the first part 301 is larger than the size of the second part 302, that is, the width of the first part 301 is greater than the width of the second part 302.

[0055] In the second direction Y, the third conveyor belt 256 and the fifth conveyor belt 25d are spaced apart, and the fourth conveyor belt 259 and the sixth conveyor belt 25g are spaced apart. Specifically, the third conveyor belt 256 and the fourth conveyor belt 259 are located above the fifth conveyor belt 25d and the sixth conveyor belt 25g, that is, the return track 25 forms an upper and lower layer structure. In the first direction X, the distance between the third conveyor belt 256 and the fourth conveyor belt 259 is greater than the distance between the fifth conveyor belt 25d and the sixth conveyor belt 25g, that is, the spacing of the upper conveyor belts is greater than the spacing of the lower conveyor belts. Therefore, the third conveyor belt 256 and the fourth conveyor belt 259 can be used together to transport the larger first part 301, and the fifth conveyor belt 25d and the sixth conveyor belt 25g can be used together to transport the smaller second part 302.

[0056] Because the third conveyor belt 256 and the fourth conveyor belt 259 are located above, and the distance between the third conveyor belt 256 and the fourth conveyor belt 259 is relatively large, when the gripping module 23 grips the smaller second part 302, it needs to pass through the gap between the third conveyor belt 256 and the fourth conveyor belt 259 from above to place the second part 302 on the fifth conveyor belt 25d and the sixth conveyor belt 25g below. Due to the large spacing between the upper conveyor belts, the gripping module 23 has ample room to maneuver when passing through the gaps, reducing the risk of interference between the gripping module 23 and the third or fourth conveyor belt 256, and improving the smoothness and efficiency of the carrier 300 retrieval process. Furthermore, by setting up two layers of conveyor belts on the same frame, the first part 301 and the second part 302, which are of different sizes, can be retrieved simultaneously without the need for two separate return tracks, thus reducing equipment costs and saving production line floor space. Meanwhile, the second drive module 253 and the third drive module 25a can independently control the movement of the upper and lower conveyor belts, allowing the first part 301 and the second part 302 to return at different speeds, which helps to improve the operational flexibility of the return track 25.

[0057] It is worth noting that after processing is completed, the PCB board 200 needs to be removed from the carrier 300 and transferred to the equipment used in the next process for further processing. Therefore, a feeding track (i.e., feeding module 26) needs to be set up to transport the processed PCB board 200, so as to realize the automated transfer of the PCB board 200 from the current process to the next process.

[0058] In some embodiments, please refer to Figure 1 , Figure 10 and Figure 11 The transport equipment 100 also includes a feeding module 26. The feeding module 26 includes a fifth upright 261, a sixth upright 262, a fourth drive module 263, a seventh drive wheel 264, a seventh driven wheel 265, a seventh conveyor belt 266, an eighth drive wheel 267, an eighth driven wheel 268, and an eighth conveyor belt 269. The fifth upright 261 and the sixth upright 262 are mounted on the mounting frame 11, and are positioned opposite each other along a first direction X. The distance between the fifth upright 261 and the sixth upright 262 matches the width of the PCB board 200. The fifth upright 261 and the sixth upright 262 respectively support the drive wheel and driven wheel of the conveyor belt.

[0059] The seventh drive wheel 264 is rotatably mounted at one end of the fifth support frame 261, and the seventh driven wheel 265 is rotatably mounted at the other end of the fifth support frame 261. A seventh conveyor belt 266 is fitted over the seventh drive wheel 264 and the seventh driven wheel 265, forming a ring. The eighth drive wheel 267 is rotatably mounted at one end of the sixth support frame 262, and the eighth driven wheel 268 is rotatably mounted at the other end of the sixth support frame 262. An eighth conveyor belt 269 is fitted over the eighth drive wheel 267 and the eighth driven wheel 268, forming a ring. A fourth drive module 263 is mounted on the mounting frame 11. Both the seventh drive wheel 264 and the eighth drive wheel 267 are connected to the fourth drive module 263. The fourth drive module 263 can simultaneously drive both the seventh drive wheel 264 and the eighth drive wheel 267 to rotate, thus causing the seventh conveyor belt 266 and the eighth conveyor belt 269 to move synchronously. The seventh conveyor belt 266 and the eighth conveyor belt 269 are used together to transport the PCB board 200.

[0060] After processing, the gripping module 23 removes the PCB board 200 from the carrier 300 and places it on the seventh conveyor belt 266 and the eighth conveyor belt 269. The seventh conveyor belt 266 carries one end of the PCB board 200, and the eighth conveyor belt 269 carries the other end. The fourth drive module 263 drives the seventh conveyor belt 266 and the eighth conveyor belt 269 to move synchronously, moving the PCB board 200 along the transport direction and transporting it to the equipment used in the next process. This facilitates the automation of the production process and reduces labor costs. By setting up the unloading module 26, the PCB board 200 can be automatically unloaded and transferred after processing, eliminating the need for manual handling, which improves production efficiency and reduces the risk of damage to the PCB board 200 during handling.

[0061] In some embodiments, the structure of the sixth support 262 is the same as or similar to that of the second support 13. Specifically, the sixth support 262 includes a guide rail, a slider, a connecting frame, a mounting plate, a locking member, and a screw connector. The guide rail is disposed on the mounting frame 11, the slider is slidably disposed on the guide rail, the connecting frame is disposed on the slider, the mounting plate is disposed on the connecting frame, the locking member is disposed on the mounting frame 11, the locking member has a through hole, and the screw connector passes through the through hole and is screwed and fixed to the connecting frame. The size of the through hole is larger than the nominal diameter of the screw connector. With the above structure, the distance between the sixth support 262 and the fifth support 261 in the first direction X can be adjusted, thereby adjusting the distance between the seventh conveyor belt 266 and the eighth conveyor belt 269 in the first direction X. When transporting PCBs 200 of different sizes, the slider is moved along the guide rail by loosening the screws, thereby adjusting the distance between the sixth stand 262 and the fifth stand 261, and consequently adjusting the distance between the seventh conveyor belt 266 and the eighth conveyor belt 269. After adjustment, the sixth stand 262 is fixed by tightening the screws. In this way, the distance between the seventh conveyor belt 266 and the eighth conveyor belt 269 can be flexibly adjusted according to the size of different PCBs 200, which helps to improve the applicability of the unloading module 26 and enable it to adapt to the unloading needs of PCBs 200 of various sizes.

[0062] In this embodiment, the first drive wheel 15 and the first driven wheel 16 are rotatably mounted on both ends of the first upright 12, the first conveyor belt 17 is fitted onto the first drive wheel 15 and the first driven wheel 16, the second drive wheel 18 and the second driven wheel 19 are rotatably mounted on both ends of the first mounting plate 134, and the second conveyor belt 20 is fitted onto the second drive wheel 18 and the second driven wheel 19. The first drive module 14 drives the first drive wheel 15 and the second drive wheel 18 to rotate, thereby driving the first conveyor belt 17 and the second conveyor belt 20 to move. The first conveyor belt 17 and the second conveyor belt 20 can jointly bear the load. The PCB board 200 is carried and moved to realize the transfer of the PCB board 200 to different workstations; the first mounting plate 134 is set on the first connecting frame 133, and the first connecting frame 133 realizes the distance between the first mounting plate 134 and the first upright frame 12 through the sliding cooperation between the first slider 132 and the first guide rail 131. Thus, the distance between the first conveyor belt 17 and the second conveyor belt 20 can be adjusted according to the PCB board 200 of different sizes, so that the transport equipment 100 can be used to transport PCB boards 200 of various sizes, thus expanding the application range of the transport equipment 100.

[0063] This application also provides a production line embodiment, which includes the aforementioned transport equipment 100. For the specific structure and function of the transport equipment 100, please refer to the above embodiments; further details will not be repeated here. By employing the aforementioned transport equipment 100, the production line can achieve automated transport, transfer, processing, and unloading of the PCB board 200, which is beneficial for improving production efficiency, reducing labor costs, and enhancing product quality stability.

[0064] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
