Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board processing technology, and in particular to a PCB board unloading machine. Background Technology
[0002] Printed circuit boards (PCBs), also known as circuit boards, are important electronic components. They are made from insulating boards cut to specific dimensions, with at least one conductive pattern and holes such as component mounting holes, mounting holes, and metallized holes. They replace the traditional chassis used for mounting electronic components and enable interconnection between these components. Because these boards are manufactured using electronic printing techniques, they are called "printed" circuit boards.
[0003] After the PCB board is manufactured, it needs to be collected. Currently, this work is usually done manually, one board at a time. However, manual collection is inefficient and has a low degree of automation, which affects the production efficiency of PCB boards. Utility Model Content
[0004] The main purpose of this utility model is to propose a PCB board unloading machine, which aims to improve the production efficiency of PCB boards.
[0005] To achieve the above objectives, the PCB board unloading machine proposed in this utility model includes:
[0006] frame;
[0007] A lifting mechanism is provided on the frame. The lifting mechanism has a placement position for placing a material frame. The lifting mechanism has a receiving position and a discharging position distributed above. The lifting mechanism receives the material frame when it is in the receiving position and transfers the material frame when it is in the discharging position.
[0008] A feeding mechanism, located on one side of the lifting mechanism, is used to transport PCB boards; and
[0009] A pushing mechanism is located on the same side of the lifting mechanism as the feeding mechanism. The pushing mechanism has a pushing member that moves toward the lifting mechanism. The pushing member is located above the feeding mechanism. The pushing member is vertically movable and has a pushing position and a clearance position located above the pushing position. In the pushing position, the pushing member is used to push the PCB board conveyed by the feeding mechanism into the material frame. In the clearance position, the pushing member is spaced apart from the feeding mechanism.
[0010] Optionally, the pushing mechanism includes two support frames and a mounting beam. The two support frames are respectively disposed on opposite sides of the frame. The two ends of the mounting beam are respectively connected to the two support frames, and the mounting beam is located at the end of the support frame away from the frame. The pushing component is installed on the mounting beam and can be raised and lowered from the mounting beam.
[0011] Optionally, the mounting beam has a through hole that penetrates the upper and lower surfaces of the mounting beam and is elongated along the length of the mounting beam. The pushing mechanism also includes a mounting plate on which the pushing mechanism is mounted. The mounting plate has screw holes that correspond to the through hole. The PCB board unloading mechanism also includes a locking screw that is screwed into the screw hole through the through hole.
[0012] Optionally, the feeding mechanism includes two mounting structures and two conveyor belts. The two mounting structures are respectively disposed on opposite sides of the frame and extend toward the direction of the lifting mechanism. The two conveyor belts are respectively disposed on two opposite side walls of the two mounting structures and located between the upper and lower sides of the mounting structures. A limiting part is formed between the conveyor belts and the upper side of the mounting structure.
[0013] Optionally, the two mounting structures are detachably configured so that the spacing between the two mounting structures is adjustable.
[0014] Optionally, the PCB unloading machine further includes an electrical control module and a sensor. The electrical control module is mounted on the frame and is electrically connected to the lifting mechanism, the feeding mechanism, the pushing mechanism, and the sensor. The sensor is located on the frame, with its sensing side facing the feeding mechanism and the end near the lifting mechanism. The sensor is configured to send an electrical signal to the electrical control module when it detects a PCB board. The electrical control module is configured to control the feeding mechanism to pause and control the pushing component to descend to the pushing position and move towards the lifting mechanism when it receives the electrical signal from the sensor.
[0015] Optionally, the PCB unloading machine further includes a conveying mechanism, which is located on the other side of the lifting mechanism. The conveying mechanism is used to convey the material frame, and the lifting mechanism corresponds to the conveying mechanism when it is located at the receiving position or the unloading position.
[0016] Optionally, the PCB unloading machine includes two conveying mechanisms, both of which are located on the other side of the lifting mechanism and are spaced vertically apart. When the lifting mechanism is in the receiving position, one of the conveying mechanisms corresponds to the lifting mechanism and is used to convey the material frame to the placement position of the lifting mechanism. When the unloading position is in the unloading position, the other conveying mechanism corresponds to the lifting mechanism and is used to receive the material frame from the placement position.
[0017] Optionally, the lifting mechanism includes a lifting component and a conveying component. The lifting component is mounted on the frame and is connected to the conveying component in a transmission manner. The lifting component is used to drive the conveying component to rise and fall.

The lifting mechanism has receiving and unloading positions distributed at its top. A feeding mechanism is positioned on one side of the lifting mechanism for conveying PCB boards. A pushing mechanism is located on the same side of the lifting mechanism as the feeding mechanism. The pushing mechanism has a pushing component that moves towards the lifting mechanism, positioned above the feeding mechanism and vertically movable.

[0033] This utility model proposes a PCB board unloading machine.
[0034] In the embodiments of this utility model, such as Figures 1 to 6 As shown, the PCB board unloading machine includes a frame 10, a lifting mechanism 20, a feeding mechanism 30, and a pushing mechanism 40.
[0035] Specifically, the lifting mechanism 20 is located on the frame 10. The lifting mechanism 20 has a placement position for placing material frames. The material frame contains multiple support parts, each supporting a PCB board. The lifting mechanism 20 has a receiving position and a discharging position distributed at the top. When in the receiving position, the lifting mechanism 20 receives the material frame; when in the discharging position, it transfers the material frame. The receiving mechanism can be located below or above the discharging position. When the lifting mechanism 20 is in the discharging position, the material frame loaded with PCBs can be transferred by the conveying mechanism 50, or the material frame loaded with PCBs can be removed from the placement position by a worker; or the material frame can be removed from the placement position by an AGV. Of course, when the lifting mechanism 20 is in the receiving position, the material frame can also be conveyed to the placement position by the conveying mechanism 50, or the material frame can be placed from the placement position by a worker; or the material frame can be placed at the placement position by an AGV.
[0036] It is worth noting that during the movement of the lifting mechanism 20 from the receiving position to the unloading position, it pauses for a certain period of time after moving a certain distance. This moving distance is set by the distance between two adjacent support parts on the adjacent material frame, so that each time the lifting mechanism 20 moves, it can move the adjacent support part to the moving axis of the pushing member 41. The pause duration of the lifting mechanism 20 can be set according to the pushing duration of the pushing member 41. For example, the pause duration of the lifting mechanism 20 can be, but is not limited to, five seconds, six seconds, seven seconds, etc. The specific setting can be determined according to the actual situation.
[0037] The feeding mechanism 30 is located on one side of the lifting mechanism 20 and is used to transport PCB boards. The pushing mechanism 40 is located on the same side of the lifting mechanism 20 as the feeding mechanism 30. The pushing mechanism 40 has a pushing member 41 that moves toward the lifting mechanism 20. The pushing member 41 is located above the feeding mechanism 30 and is vertically movable. It has a pushing position and a clearance position above the pushing position. In the pushing position, the pushing member 41 is used to push the PCB board transported by the feeding mechanism 30 into the material frame. In the clearance position, the pushing member 41 is spaced apart from the feeding mechanism 30 to prevent the pushing member 41 from interfering with the feeding mechanism 30 and affecting the transport of the PCB board by the pushing member 41.
[0038] When the PCB board conveyed by the feeding mechanism 30 corresponds to the lifting mechanism 20, the feeding will be paused. The pushing component 41 will descend to the pushing position and move towards the lifting mechanism 20. During the movement of the pushing component 41 towards the lifting mechanism 20, the pushing component 41 will push the PCB board on the feeding mechanism 30 into the material frame. After the pushing component 41 pushes the PCB board into the material frame, the lifting mechanism 20 will rise or fall to move the adjacent support part to the pushing axis of the pushing component 41.
[0039] Specifically, in some embodiments, the receiving position is located below the unloading position. That is, the lifting mechanism 20 receives the material frame at a low position and then moves towards the unloading position after receiving the material frame.
[0040] In another embodiment, the receiving position is located above the unloading position. That is, the lifting mechanism 20 receives the PCB board loading frame at a high position, and after receiving the frame, moves towards the unloading position. The specific configuration can be adjusted according to actual conditions, and this application does not impose any specific limitations.
[0041] In practical use, the feeding mechanism 30 conveys the PCB board. When the PCB board is conveyed to the position of the lifting mechanism 20, the feeding mechanism 30 stops conveying, the pushing component 41 descends to the pushing position and moves toward the lifting mechanism 20 to push the PCB board into the material frame. Subsequently, the pushing component 41 moves to the avoidance position, and the feeding mechanism 30 continues to convey the PCB board. The lifting mechanism 20 moves a certain distance toward the unloading position and then pauses. When the PCB board conveyed by the feeding mechanism 30 is at the position of the lifting mechanism 20, the pushing component 41 descends to the pushing position and moves toward the lifting mechanism 20 to push the PCB board into the material frame. This process is repeated until the material frame is full of PCB boards. After the material frame full of PCB boards is removed from the placement position, the lifting mechanism 20 moves to the receiving mechanism, places the empty material frame in the placement position, and repeats the above steps, thereby realizing the mechanical automation of PCB board collection and loading.
[0042] The present invention provides a lifting mechanism 20 mounted on a frame 10. The lifting mechanism 20 has a placement position for placing a material frame. The lifting mechanism 20 has a receiving position and a discharging position distributed at the top. A feeding mechanism 30 is mounted on one side of the lifting mechanism 20 and is used to transport PCB boards. A pushing mechanism 40 is mounted on the same side of the lifting mechanism 20 as the feeding mechanism 30. The pushing mechanism 40 has a pushing component 41 that moves toward the lifting mechanism 20. The pushing component 41 is located above the feeding mechanism 30 and can be raised and lowered. The pushing component 41 has a pushing position and a clearance position located above the pushing position. In the pushing position, the pushing component 41 is used to push the PCB board transported by the feeding mechanism 30 into the material frame. In the clearance position, the pushing component 41 is spaced apart from the feeding mechanism 30. In this way, the PCB board is transported by the feeding mechanism 30, and the PCB board transported by the feeding mechanism 30 is pushed into the material frame by the pushing mechanism 40. The material frame is used to load the PCB board, realizing the automated collection and loading of PCB board, saving labor and improving the production efficiency of PCB board.
[0043] In some embodiments, the pushing mechanism 40 includes two support frames 42 and a mounting beam 43. The two support frames 42 are respectively disposed on opposite sides of the frame 10. The two ends of the mounting beam 43 are respectively connected to the two support frames 42, and the mounting beam 43 is located at the end of the support frame 42 away from the frame 10. The pushing component 41 is mounted on the mounting beam 43 and can be raised and lowered from the mounting beam 43. That is, the mounting beam 43 is mounted by the two support frames 42, and the pushing component 41 is mounted by the mounting beam 43. This arrangement helps to reduce the installation difficulty of the pushing component 41.
[0044] In some embodiments, the pushing component 41 includes a driving component 411 and a pushing component 412. The driving component 411 is mounted on the mounting beam 43 and connected to the pushing component 412. The driving component 411 is used to drive the pushing component 412 to move toward the lifting mechanism 20.
[0045] The drive assembly 411 includes a motor, two drive pulleys, and a drive belt. The motor is mounted on the mounting beam 43. One drive pulley is fitted onto the motor's output shaft, and the other drive pulley is mounted on the mounting beam 43. The drive belt is fitted onto the two drive pulleys, and the push assembly 412 is connected to the drive belt. That is, the motor drives the drive pulleys to rotate, which in turn drives the drive belt, which in turn moves the push assembly 412. The direction of movement of the push assembly 412 can be controlled by rotating the motor.
[0046] In some embodiments, the mounting beam 43 is provided with a through hole that penetrates the upper and lower surfaces of the mounting beam 43 and is in the shape of an elongated strip extending along the length of the mounting beam 43. The pushing mechanism 40 also includes a mounting plate 44, on which the driving assembly 411 and the pushing assembly 412 are both mounted. The mounting plate 44 is provided with screw holes that correspond to the through hole. The PCB board lowering mechanism also includes a locking screw that is screwed into the screw hole through the through hole.
[0047] Specifically, the mounting plate 44 is detachable. When the position of the pushing member 41 against the PCB board is biased to one side, the position of the pushing member 41 can be adjusted, which in turn adjusts the position of the mounting plate 44. This allows the mounting beam 43 of the mounting plate 44 to move along its length. After adjustment, the position can be fixed by tightening screws, so that during the movement of the pushing member 41, the pushing component 412 abuts against the middle of the PCB board, which helps improve the pushing stability of the PCB board. Of course, in other embodiments, the mounting plate 44 is fixedly mounted on the mounting beam 43.
[0048] In some embodiments, the PCB board unloading machine further includes an electrical control module and a sensor. The electrical control module is mounted on the frame 10 and is electrically connected to the lifting mechanism 20, the feeding mechanism 30, the pushing mechanism 40, and the sensor. The sensor is located on the frame 10, with its sensing side facing the end of the feeding mechanism 30 near the lifting mechanism 20. The sensor is configured to send an electrical signal to the electrical control module when it detects a PCB board. The electrical control module is configured to control the feeding mechanism 30 to pause conveying and control the pushing component 412 to descend to the pushing position and move toward the lifting mechanism 20 when it receives the electrical signal from the sensor.
[0049] Specifically, when the sensor detects a PCB being conveyed by the feeding mechanism 30, it sends a first detection signal to the electronic control module. Upon receiving the first detection signal, the electronic control module controls the feeding mechanism 30 to pause conveying and controls the pushing component 412 to descend to the pushing position and move towards the lifting mechanism 20. When the sensor cannot detect the PCB, it sends a second detection signal. Upon receiving the second detection signal, the electronic control module controls the feeding mechanism 30 to continue conveying the PCB and controls the pushing component 412 to rise to the avoidance position. Optionally, the sensor can be an infrared sensor or a laser sensor.
[0050] In some embodiments, the feeding mechanism 30 includes two mounting structures 31 and two conveyor belts 32. The two mounting structures 31 are respectively disposed on opposite sides of the frame 10 and extend toward the direction of the lifting mechanism 20. The two conveyor belts 32 are respectively disposed on opposite side walls of the two mounting structures 31 and are located between the upper and lower sides of the mounting structures 31. A limiting part is formed between the conveyor belts 32 and the upper side of the mounting structure 31.
[0051] Specifically, the limiting part is used to limit the PCB board to prevent the PCB board from deviating during transportation or placement, which would affect the subsequent pushing of the PCB board by the pushing component 41. This setting helps to improve the pushing smoothness of the pushing component 412.
[0052] In some embodiments, the two mounting structures 31 are detachably configured so that the distance between them is adjustable. Since PCBs have different sizes, the detachable configuration of the two mounting structures 31 allows for adjustment of the distance between them according to the size of the PCB, enabling positioning of PCBs of different sizes. This improves the practicality of the PCB board mounting mechanism. Of course, in other embodiments, the two mounting structures 31 are fixedly mounted to the frame.
[0053] In some embodiments, the PCB board unloading machine further includes a conveying mechanism 50, which is located on the other side of the lifting mechanism 20. The conveying mechanism 50 is used to convey the material frame, and the lifting mechanism 20 corresponds to the conveying mechanism 50 when it is in the receiving position or the unloading position.
[0054] Specifically, the conveying mechanism 50 is used to transport empty material frames to the lifting mechanism 20 or to transfer material frames loaded with PCB boards, so as to realize the automation of material frame loading or unloading. This configuration helps to reduce labor costs. Of course, in other embodiments, the PCB board loading machine does not have a feeding mechanism 30.
[0055] Furthermore, the PCB unloading machine includes two conveying mechanisms 50, both of which are located on the other side of the lifting mechanism 20 and are spaced vertically apart. When the lifting mechanism 20 is in the receiving position, one of the conveying mechanisms 50 corresponds to the lifting mechanism 20 and is used to convey the material frame to the placement position of the lifting mechanism 20. When the unloading position is in the unloading position, the other conveying mechanism 50 corresponds to the lifting mechanism 20 and is used to receive the material frame from the placement position.
[0056] Specifically, one conveying mechanism 50 is used to transport the material frame to the lifting mechanism 20, and the other conveying mechanism 50 is used to transfer the material frame loaded with PCB boards, so as to realize the mechanical automation of the material frame loading and unloading of the PCB board unloading machine, which helps to reduce labor costs. Moreover, multiple material frames can be placed on the conveying mechanism 50 at one time, instead of placing them one by one, which helps to improve the continuity of work and thus improve work efficiency.
[0057] To facilitate understanding of this scheme, it is assumed that the two conveying mechanisms 50 are the first conveying mechanism 50 and the second conveying mechanism 50, and the first feeding mechanism 30 is located below the second feeding mechanism 30.
[0058] Specifically, in one embodiment, the receiving position is located below the unloading position, that is, the lifting mechanism 20 corresponds to the first feeding mechanism 30, and is used to receive the empty material frame conveyed by the first feeding mechanism 30. After receiving the material frame, it moves upward. When the lifting mechanism 20 corresponds to the second feeding mechanism 30, the lifting mechanism 20 is located at the unloading position. At this time, the material frame is fully loaded with PCB boards, and the material frame is sent away by the second feeding mechanism 30. After the material frame is removed, the lifting mechanism 20 returns to the receiving position and repeats the above steps.
[0059] When the receiving position is above the unloading position, i.e., the lifting mechanism 20 corresponds to the second feeding mechanism 30, it receives the empty material frame conveyed by the second feeding mechanism 30 and moves downward after receiving the material frame. When the lifting mechanism 20 corresponds to the first feeding mechanism 30, the lifting mechanism 20 is in the unloading position. At this time, the material frame is fully loaded with PCB boards, and the material frame is sent away by the first feeding mechanism 30. After the material frame is removed, the lifting mechanism 20 returns to the receiving position and repeats the above steps.
[0060] This configuration allows the lifting mechanism 20 to select one of the feeding mechanisms 30 to receive materials. For example, when the user is weak, the material frame can be placed on the second feeding mechanism 30 to transport the empty material frame.
[0061] In some embodiments, the lifting mechanism 20 includes a lifting component 21 and a conveying component 22. The lifting component 21 is mounted on the frame 10 and is connected to the conveying component 22 in a transmission manner. The lifting component 21 is used to drive the conveying component 22 to rise and fall. The conveying component 22 is provided with a placement position. The conveying direction of the conveying component 22 is parallel to the moving direction of the pushing component 41.
[0062] Specifically, when the conveying mechanism 50 conveys the material frame to the placement position on the conveying component 22, the conveying component 22 can drive the material frame to move towards the feeding mechanism 30 to shorten the distance between the material frame and the feeding mechanism 30, and prevent the PCB board from being unable to be pushed into the receiving mechanism due to the excessive distance between the material frame and the feeding mechanism 30.
[0063] In some embodiments, the inner wall of the conveying component 22 near the feeding mechanism 30 is provided with a protruding stop portion, which is spaced apart from the surface of the conveying component 22.
[0064] Specifically, the stop portion is used to limit the material frame and prevent it from sliding out of the end of the conveying component 22 near the feeding mechanism 30. Optionally, both inner walls of the conveying component 22 near the feeding mechanism 30 are provided with protruding stop portions. Alternatively, the inner wall of the end of the conveying component 22 near the feeding mechanism 30 is provided with a protruding stop portion, the inner wall of the opposite side of the stop portion extends and is spaced apart from the surface of the conveying component.
[0065] In some embodiments, the PCB board-mounted machine further includes a scanning mechanism 60, which is mounted on the frame 10 with its scanning side facing the placement position. Specifically, the scanning mechanism 60 is used to scan the material frame on the placement position and upload the information to the system for registration of the material frame information. Of course, in other embodiments, the PCB board-mounted machine does not include a scanning mechanism 60.
[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
