Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to a PCB board lifting machine. Background Technology
[0002] In the electronics manufacturing industry, the conveying and handling of PCBs (printed circuit boards) is a crucial step. With continuous technological advancements, the sizes and shapes of PCBs are becoming increasingly diverse, placing higher demands on PCB conveying equipment. Traditional lifting machines often encounter several problems when lifting PCBs, the most prominent being the lack of effective limiting measures for the PCBs and a lack of flexibility in handling PCBs of different sizes.
[0003] First, during the lifting process, the PCB board may shift or slip due to factors such as vibration and inertia. This may not only damage the PCB board, but also damage the conveying equipment, and even affect the normal operation of the entire production line.
[0004] Secondly, traditional lifting platforms have limitations when handling PCBs of different sizes. Due to the varying sizes and shapes of PCBs, traditional lifting platforms often cannot adapt to this diversity, leading to frequent changes in conveying equipment or adjustments to equipment parameters in practical applications. This not only increases production costs but also reduces production efficiency. Therefore, a PCB lifting platform is provided to solve the aforementioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a PCB board lifting machine to address the shortcomings of the existing technology, thereby solving the technical problems that the existing lifting machines do not have limit treatment for the PCB board during the lifting process and cannot adapt to PCB boards of various sizes.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A PCB board lifting machine includes a support frame and a housing disposed on the support frame. The support frame is provided with a lifting platform that can move up and down, and the lifting platform is equipped with a receiving component for receiving and conveying PCB boards.
[0008] The receiving component includes a fixed seat mounted on the lifting platform and a movable seat that can move towards or away from the fixed seat. The movable seat is equipped with a left conveying part, and the fixed seat is equipped with a right conveying part that cooperates with the left conveying part to receive the PCB board. Limiting components for limiting the PCB board during the lifting process are installed at the beginning and end of the movable seat and at the beginning and end of the fixed seat.
[0009] Furthermore, the sides of the housing are formed with upper and lower openings arranged vertically for the PCB board to pass through.
[0010] Furthermore, the support frame is provided with several vertically arranged first guide rails, and the lifting platform is slidably mounted on the first guide rails.
[0011] Furthermore, the lifting platform is provided with a horizontally arranged guide rod, the length direction of which is perpendicular to the conveying direction of the PCB board, and the movable seat is slidably mounted on the guide rod; a lead screw with an axis parallel to the axis of the guide rod is rotatably provided on the lifting platform, and the lead screw is threadedly connected to the movable seat.
[0012] Furthermore, the left conveying section includes a first sprocket and a second sprocket rotatably disposed at both ends of the movable seat along its length and at the same level. The length direction of the movable seat is consistent with the conveying direction of the PCB board. A first chain for conveying the PCB board is wound around the first sprocket and the second sprocket, and each pin of the first chain is provided with a material support part for supporting the PCB board. The movable seat is equipped with a first servo motor, and a third sprocket is provided at the end of the output shaft of the first servo motor. The lower half of the first chain is wound around the third sprocket.
[0013] Furthermore, the limiting component includes a cylinder, the cylinder is arranged laterally and the telescopic rod is directed toward the conveying trajectory of the PCB board, and each cylinder is equipped with a limiting plate for limiting the PCB board at the end of the telescopic rod; each limiting plate is provided with a soft pad on the side facing the material support.
[0014] Furthermore, the housing is equipped with control components for controlling the lifting platform to move up and down on the support frame.
[0015] Furthermore, the control component includes a first support base installed at the bottom of the housing and a first rotating shaft rotatably mounted on the first support base. The first rotating shaft is arranged laterally and a fourth sprocket is mounted on the first rotating shaft. A second support base is installed at the top of the housing. A second rotating shaft is rotatably mounted on the second support base, positioned directly above the first rotating shaft and with its axis parallel to the axis of the first rotating shaft. A fifth sprocket is mounted on the second rotating shaft, and a second chain is wound around the fifth sprocket and the fourth sprocket.
[0016] The support frame is equipped with a counterweight module that can move up and down. A portion of one side of the second chain is fixedly connected to the lifting platform, and a portion of the other side of the second chain is fixedly connected to the counterweight module.

[0028] The following is a detailed description of a PCB board lifting machine according to the present invention, with reference to the accompanying drawings.
[0029] like Figure 1-2 As shown, an embodiment of the PCB board lifting machine of this utility model includes a support frame 1 and a housing 2 disposed on the support frame 1. The support frame 1 is provided with a lifting platform 3 that can move up and down. The lifting platform 3 is placed inside the housing 2. The lifting platform 3 is equipped with a receiving component 4 for receiving and conveying PCB boards. When the receiving component 4 receives a single PCB board or multiple stacked PCB boards, it controls the lifting platform 3 to move up and down on the support frame 1, thereby realizing the lifting and lowering of a single PCB board or multiple stacked PCB boards, which facilitates the conveying of the PCB boards to another conveying device (not shown in the figure) for subsequent processing.
[0030] Specifically, an upper opening 202 and a lower opening 201 are formed on the side of the outer casing 2, arranged vertically. The upper opening 202 and the lower opening 201 are respectively connected to different conveying devices (not shown in the figure). When the control lifting platform 3 moves downward to the lowest point on the support frame 1, the receiving component 4 can connect with the lower opening 201. At the same time, the receiving component 4 and the conveying device (not shown in the figure) connected to the lower opening 201 are operated, so that the receiving component 4 receives the PCB board conveyed by the conveying device (not shown in the figure), thereby conveying a single PCB board or multiple stacked PCB boards to the designated position on the receiving component 4. Then, the control lifting platform 3 is activated. The lowering platform 3 moves upwards on the support frame 1 to its highest point, thereby connecting with the upper opening 202. Simultaneously, the receiving component 4 and the conveying device (not shown in the figure) connected to the upper opening 202 operate, conveying a single PCB board or multiple stacked PCB boards to the conveying device (not shown in the figure), completing the upward conveying process of the PCB boards. Conversely, when the receiving component 4 connects to the upper opening 202, it can also receive PCB boards conveyed by the conveying device (not shown in the figure), and then move downwards to its lowest point, conveying the PCB boards to the conveying device (not shown in the figure) connected to the lower opening 201. The positions of the upper opening 202 and the lower opening 201 are set according to the conveying device (not shown in the figure) to be connected. This lifting platform allows for the connection of conveying devices (not shown in the figure) of different heights, enabling the lifting and conveying of PCB boards during the conveying process. This overcomes the problem of the inability to connect conveying devices (not shown in the figure) of different heights, improving the conveying efficiency of PCB boards.
[0031] In addition, the housing 2 is equipped with a control component for controlling the lifting platform 3 to move automatically up and down on the support frame 1; by operating the control component, the lifting platform 3 can be raised or lowered to a specified height, thereby realizing the lifting and lowering of a single PCB board or multiple stacked PCB boards.
[0032] Additionally, several vertically arranged first guide rails 301 are provided on the support frame 1, and the lifting platform 3 is slidably mounted on the first guide rails 301. By setting the first guide rails 301, the lifting platform 3 can stably move up and down on the support frame 1. A door frame 203 is also provided on the side of the outer casing 2. After opening the door frame 203, the various components inside the outer casing 2 can be repaired or maintained.
[0033] like Figure 3As shown, the receiving component 4 includes a fixed seat 401 mounted on the lifting platform 3 and a horizontally arranged guide rod 403. The length direction of the guide rod 403 is perpendicular to the conveying direction of the PCB board, and a movable seat 404 is slidably provided on the guide rod 403. After applying force to the movable seat 404, the movable seat 404 slides on the guide rod 403 in a direction closer to or away from the fixed seat 401. The movable seat 404 is equipped with a left conveying section 405, and the fixed seat 401 is equipped with a right conveying section 402 that cooperates with the left conveying section 405 to receive PCB boards. When the initial ends of the left conveying section 405 and the right conveying section 402 are connected to other conveying equipment (not shown in the figure), the left conveying section 405 and the right conveying section 402 are operated simultaneously to receive the PCB boards conveyed by the conveying equipment (not shown in the figure). When the control lifting platform 3 is raised or lowered to a specified height and connected to another conveying equipment (not shown in the figure), the left conveying section 405 and the right conveying section 402 are operated simultaneously again to convey the PCB boards to the connected conveying equipment (not shown in the figure), thus completing the lifting and conveying of the PCB boards. To receive PCBs of different sizes, a lead screw 406 with its axis parallel to the axis of the guide rod 403 is rotatably mounted on the lifting platform 3, and the lead screw 406 is threadedly connected to the movable seat 404. By driving the lead screw 406 to rotate, the movable seat 404 can be controlled to slide on the guide rod 403 in a direction closer to or further away from the fixed seat 401, thereby adjusting the distance between the left conveying section 405 and the right conveying section 402 to accommodate PCBs of different sizes, thus improving the practicality of this lifting frame.
[0034] In addition, limiting components 5 are installed at the beginning and end of the movable seat 404 and at the beginning and end of the fixed seat 401 to limit the PCB board during the lifting process. After the left conveying part 405 and the right conveying part 402 have received the PCB board, multiple limiting components 5 operate simultaneously to limit the two sides of the PCB board, preventing the PCB board from detaching from the left conveying part 405 and the right conveying part 402 due to vibration during the lifting process. Under the action of the limiting components 5, the lifting process is more stable.
[0035] The left conveying unit 405 and the right conveying unit 402 have the same structure and the same operation mode. The left conveying unit 405 includes a first sprocket 4051 and a second sprocket 4052 that are rotatably disposed at both ends of the movable seat 404 along the length direction and are at the same level. The length direction of the movable seat 404 is consistent with the conveying direction of the PCB board. A first chain 4053 for conveying the PCB board is wound around the first sprocket 4051 and the second sprocket 4052. Each pin of the first chain 4053 is provided with a material support part 4054 for supporting the PCB board. After the PCB board is received by the first chain 4053, the PCB board is placed on the material support part 4054. After the first chain 4053 is driven to move, the PCB board can be conveyed. The movable seat 404 is also equipped with a first servo motor 4055. The output shaft end of the first servo motor 4055 is provided with a third sprocket 4056. The lower half of the first chain 4053 is wound around the third sprocket 4056. Running the first servo motor 4055 will cause the third sprocket 4056 to rotate, and the third sprocket 4056 will drive the first chain 4053 to move, so as to transport the PCB board.
[0036] Furthermore, the limiting component 5 includes a cylinder 502 and a mounting member 501 that mounts the cylinder 502 on the end of the movable seat 404 (or the end of the fixed seat 401). The cylinder 502 is arranged laterally with its telescopic rod facing the conveying trajectory of the PCB board. A limiting plate 503 for limiting the PCB board is installed on the end of the telescopic rod of each cylinder 502. Running the cylinder 502 pushes the limiting plate 503 onto the conveying trajectory of the PCB board, thereby limiting the PCB board placed on the support section 4054 and preventing the PCB board from detaching from the support section 4054 along the conveying trajectory during the lifting and lowering process. In addition, a soft pad 504 is provided on the side of each limiting plate 503 facing the support section 4054. The limiting plate 503 contacts the PCB board through the soft pad 504 to prevent collisions during the lifting and lowering process of the PCB board.
[0037] like Figure 4-5 As shown, the control component includes a first support base 6 installed at the bottom of the housing 2 and a first rotating shaft 7 rotatably mounted on the first support base 6. The first rotating shaft 7 is arranged laterally and a fourth sprocket 8 is mounted on it. A second support base 9 is installed at the top of the housing 2. A second rotating shaft 10 is rotatably mounted on the second support base 9, positioned directly above the first rotating shaft 7 and with its axis parallel to the axis of the first rotating shaft 7. A fifth sprocket 11 is mounted on the second rotating shaft 10, and a second chain 12 is wound around the fifth sprocket 11 and the fourth sprocket 8. By setting the fourth sprocket 8 and the fifth sprocket 11 at the bottom and top of the housing 2, respectively, the second chain 12 can be controlled to move vertically and parallel to the direction of movement of the lifting platform 3 when the first rotating shaft 7 (or the second rotating shaft 10) is driven to rotate.
[0038] When the second chain 12 is controlled to move, one side of the chain segment moves upward, while the other side moves downward. A lifting frame 17, which can move up and down, is provided on the support frame 1, and several counterweights 18 are installed inside the lifting frame 17. A portion of one side of the second chain 12 is fixedly connected to the lifting platform 3, and a portion of the other side of the second chain 12 is fixedly connected to the lifting frame 17. When the second chain 12 is controlled to move, causing the lifting platform 3 to move upward, the lifting frame 17 will move downward on the support frame 1; conversely, when the lifting platform 3 is moved downward, the lifting frame 17 will move upward. By setting several counterweights 18, the forces on the two sides of the second chain 12 are opposite, achieving a balanced effect and preventing damage to the second chain 12 caused by unilateral force.
[0039] Additionally, the lifting frame 17 and the second chain 12, as well as the lifting platform 3 and the second chain 12, are fixedly connected by the first connecting block 13. This connection facilitates the installation and disassembly of the second chain 12, and allows for easy maintenance and repair. A vertically arranged second guide rail 16 is mounted on the support frame 1, and the lifting frame 17 is slidably mounted on the second guide rail 16. The second guide rail 16 enhances the stability of the lifting frame 17 as it slides up and down on the support frame 1.
[0040] In order to control the movement of the second chain 12, a second servo motor 14 is installed inside the housing 2, and the output shaft of the second servo motor 14 is connected to the first rotating shaft 7 (or the second rotating shaft 10) through a transmission component 15. Running the second servo motor 14 drives the first rotating shaft 7 (or the second rotating shaft 10) to rotate through the transmission component 15, thereby controlling the movement of the second chain 12, driving the lifting platform 3 to move up and down, so as to drive the PCB board to move up and down.
[0041] In addition, to make the lifting platform 3 more stable when moving up and down, a third support base 20 is installed at the top inside the outer casing 2. The third support base 20 is rotatably equipped with a third rotating shaft 21 whose axis is parallel to the axis of the second rotating shaft 10 and at the same height. A seventh sprocket 22 is installed on the third rotating shaft 21. A sixth sprocket 19 is also installed on the second rotating shaft 10. A long strip of third chain 23 is wound around the sixth sprocket 19 and the seventh sprocket 22. One end of the third chain 23 is fixedly connected to the side of the lifting platform 3 away from the first connecting block 13, and the other end of the third chain 23 is fixedly connected to the lifting frame 17. When the second chain 12 moves, the third chain 23 also moves, so that the second chain 12 and the third chain 23 apply the same force to both sides of the lifting platform 3, making the lifting platform 3 more stable when moving up and down and improving the lifting effect on the PCB board.
[0042] Additionally, the lifting frame 17 and one end of the third chain 23, as well as the lifting platform 3 and the other end of the third chain 23, are fixedly connected by the second connecting block 24. The connection via the second connecting block 24 facilitates the installation and removal of the second chain 12.
[0043] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
[0044] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
