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] Currently, automatic unloading machines have appeared on the market. These machines consist of a feeding mechanism, a lifting mechanism, and a pushing mechanism. The automatic unloading machine pushes the PCB boards delivered by the feeding mechanism into the material board through the pushing mechanism. In the overall PCB board production system, the processing equipment upstream of the automatic unloading machine can only be spliced ​​at the end of the automatic unloading machine, that is, the receiving end of the feeding mechanism, which makes the overall production system require a large length space. Utility Model Content

[0004] The main purpose of this utility model is to propose a PCB board unloading machine, which aims to reduce the length and space occupied by the PCB board production system.

[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 vertically. 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 and above the feeding mechanism. The pushing mechanism has a pushing member that moves toward the lifting mechanism. The moving direction of the pushing member is perpendicular to the conveying direction of the feeding mechanism. The pushing member is used to push the PCB board into the material frame. The pushing member is vertically detachable and has a pushing position and a clearance position 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 feeding mechanism is rotatably mounted on the frame and has a feeding component that conveys PCB boards. The feeding component has a first state and a second state. In the first state, the conveying direction of the feeding component is parallel to the moving direction of the pushing component. In the second state, the conveying direction of the feeding component intersects with the extending direction of the pushing component. The feeding component is configured to start working when the pushing component pushes the PCB board and to stop working after receiving the PCB board.

[0011] Optionally, the feeding mechanism includes a rotating component, a mounting plate, and multiple auxiliary wheels. The rotating component is mounted on the mounting plate and is connected to the feeding component in a transmission manner. The mounting plate is mounted on the frame and spaced apart from the feeding component. The multiple auxiliary wheels are disposed between the mounting plate and the feeding component and are circumferentially distributed along the rotation axis of the rotating component.

[0012] Optionally, the feeding component includes a mounting base and a feeding assembly, a plurality of auxiliary wheels are disposed between the mounting base and the mounting plate, the rotating component is throttle-connected to the mounting base, the feeding assembly is slidably mounted on the mounting base, and the feeding assembly has a first state and a second state.

[0013] Optionally, the feeding assembly 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.

[0014] Optionally, the two mounting structures are detachably configured so that the spacing between the two mounting structures is adjustable.

[0015] 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 conveying component is provided with the placement position. The conveying direction of the conveying component is parallel to the moving direction of the pushing component.

[0016] Optionally, the inner wall of the conveying component near the feeding mechanism is provided with a protruding stop portion, which is spaced apart from the surface of the conveying component.

[0017] 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.

[0018] 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.

[0019] This utility model's technical solution involves placing a lifting mechanism on the frame and providing a placement position for the material frame. The lifting mechanism has vertically distributed receiving and unloading positions. When in the receiving position, the lifting mechanism receives the material frame, and when in the unloading position, it transfers the material frame. A feeding mechanism is located on one side of the lifting mechanism to transport the PCB board. A pushing mechanism is located on the same side of the lifting mechanism, above the feeding mechanism. The pushing mechanism has a pushing component that moves towards the lifting mechanism, with its movement direction perpendicular to the feeding mechanism's conveying direction. The pushing component pushes the PCB board into the material frame. This arrangement allows the pushing component to move towards the lifting mechanism, and its movement direction intersects with the feeding mechanism's conveying direction (i.e., the feeding mechanism's conveying direction faces the side of the frame). This configuration allows the upstream processing equipment of the PCB board unloading machine to be attached to the side of the PCB board unloading machine. Compared to the traditional method where the upstream processing equipment is attached to the end of the PCB board unloading machine, this reduces the overall length and space occupied by the PCB board production system.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text is to include three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0034] This utility model proposes a PCB board unloading machine.

[0035] In the embodiments of this utility model, such as Figures 1 to 7 As shown, the PCB board unloading machine includes a frame 10, a lifting mechanism 20, a feeding mechanism 30, and a pushing mechanism 40.

[0036] Specifically, the lifting mechanism 20 is located on the frame 10. The lifting mechanism 20 has a placement position for placing a material frame. The material frame contains multiple support parts, each supporting a PCB board. The lifting mechanism 20 has vertically distributed receiving and unloading positions. When in the receiving position, the lifting mechanism 20 receives the material frame; when in the unloading position, it transfers the material frame. The receiving position can be located below or above the unloading position. When the lifting mechanism 20 is in the unloading 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. Conversely, 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 in the placement position by an AGV.

[0037] 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.

[0038] 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 and above the feeding mechanism 30. The pushing mechanism 40 has a pushing component 41 that moves toward the lifting mechanism 20. The moving direction of the pushing component 41 intersects with the conveying direction of the feeding mechanism 30, that is, the conveying direction of the feeding mechanism 30 points to the side of the frame 10. The feeding mechanism 30 receives the PCB boards transported from the upstream side from the side of the frame 10. In other words, the processing equipment on the upstream side of the PCB board unloading machine is spliced ​​on the side of the PCB board unloading machine.

[0039] The pushing member 41 is used to push the PCB board into the material frame. The pushing member 41 is vertically adjustable and 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 conveyed 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.

[0040] 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 pushing component 41 will rise to the avoidance position and move away from the lifting mechanism 20 to wait for the next push. The lifting mechanism 20 will then move towards the unloading position to move the adjacent support part to the pushing axis of the pushing component 41.

[0041] 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.

[0042] 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.

[0043] In practical use, the feeding mechanism 30 receives and transports PCB boards from the upstream side. When the PCB board is transported to the position corresponding to the lifting mechanism 20, the feeding mechanism 30 stops transporting, 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 clearance position, and the feeding mechanism 30 continues to receive and transport PCB boards, repeating the above steps 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 position, 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.

[0044] The present invention provides a lifting mechanism 20 mounted on a frame 10, with a placement position for placing a material frame. The lifting mechanism 20 has a receiving position and a discharging position distributed vertically. The lifting mechanism 20 receives the material frame when in the receiving position and transfers the material frame when in the discharging position. A feeding mechanism 30 is mounted on one side of the lifting mechanism 20 to transport PCB boards. A pushing mechanism 40 is mounted on the same side of the lifting mechanism 20 as the feeding mechanism 30 and located above the feeding mechanism 30. The pushing mechanism 40 has a pushing component 41 that moves toward the lifting mechanism 20. The moving direction of the pushing component is perpendicular to the conveying direction of the feeding mechanism 30. The pushing component 41 is used to push the PCB board into the material frame. This arrangement allows the pushing component to move towards the lifting mechanism 20, and the direction of movement of the pushing component intersects with the conveying direction of the feeding mechanism 30, i.e., the conveying direction of the feeding mechanism 30 is towards the side of the frame 10. This arrangement allows the upstream processing equipment of the PCB board unloading machine to be spliced ​​on the side of the PCB board unloading machine. Compared with the traditional method of splicing the upstream processing equipment of the PCB board unloading machine at the end of the PCB board unloading machine, this helps to reduce the space occupied by the overall length of the PCB board production system.

[0045] In some embodiments, the feeding mechanism 30 is rotatably mounted on the frame 10 and has a feeding component 31 that feeds PCB boards. The feeding component 31 has a first state and a second state. In the first state, the feeding direction of the feeding component 31 intersects with the moving direction of the pushing component 41. In the second state, the feeding direction of the feeding component 31 is parallel to the extending direction of the pushing component 41. The feeding component 31 is configured to start working when the pushing component 41 pushes the PCB board and to stop working after receiving the PCB board.

[0046] Specifically, when the feeding component 31 is in the first state, it receives the PCB board from the upstream processing equipment of the PCB board unloading machine. After receiving the PCB board, it rotates to the second state, so that the feeding component 31 is in the second state to transport the PCB board towards the lifting mechanism 20. When the pushing component 41 moves towards the lifting mechanism 20 to push the PCB board, the feeding component 31 is in operation. This avoids friction between the PCB board and the feeding component 31 due to the pushing component 41, which helps to improve the yield rate of PCB board production.

[0047] In some embodiments, the feeding mechanism 30 includes a rotating component 32, a mounting plate 33, and a plurality of auxiliary wheels 34. The rotating component 32 is mounted on the mounting plate 33 and is connected to the feeding component 31 in a transmission manner. The mounting plate 33 is mounted on the frame 10 and spaced apart from the feeding component 31. The plurality of auxiliary wheels 34 are disposed between the mounting plate 33 and the feeding component 31 and are circumferentially distributed along the rotation axis of the rotating component 32.

[0048] Specifically, the number of auxiliary wheels 34 is at least two. The rotating component 32 drives the feeding component 31 to rotate. When the rotating component 32 drives the feeding component 31 to rotate, the multiple auxiliary wheels 34 can provide an auxiliary effect, making the rotation of the feeding part smoother and improving the smoothness of the rotation of the feeding component 31. The multiple auxiliary wheels 34 can be mounted on the mounting plate 33 or on the feeding component 31. For example, the number of auxiliary wheels 34 can be, but is not limited to, two, three, four, etc. Of course, in other embodiments, the feeding mechanism 30 may not be equipped with auxiliary wheels 34.

[0049] In some embodiments, the feeding component 31 includes a mounting base 311 and a feeding assembly 312, a plurality of auxiliary wheels 34 are disposed between the mounting base 311 and the mounting plate 33, the rotating component 32 is connected to the mounting base 311 in a transmission manner, the feeding assembly 312 is slidably mounted on the mounting base 311, and the feeding assembly 312 has a first state and a second state.

[0050] Specifically, when the feeding assembly 312 is in the second state, it can slide towards the lifting mechanism 20, while when it is in the first state, it can slide laterally towards the frame 10. This arrangement allows the feeding assembly 312 to slide towards the lifting mechanism 20 in the second state, shortening the distance between them and facilitating the pushing component 41 to push the PCB board into the material frame. When the feeding assembly 312 is in the second state, it slides laterally towards the frame 10, shortening the distance to the upstream processing equipment, thus facilitating the receiving of the PCB board.

[0051] Furthermore, one of the mounting base 311 and the feeding assembly 312 is provided with a slide rail 35, and the other is provided with a slider 36. The slider 36 is slidably mounted on the slide rail 35, which extends along the sliding direction of the feeding assembly 312. The feeding component 31 also includes a driving member 70, which is mounted on the mounting base 311 and is connected to the feeding component 31 in a transmission manner to drive the feeding component 31 to slide.

[0052] In some embodiments, the feeding assembly 312 includes two mounting structures 3121 and two conveyor belts. The two mounting structures 3121 are respectively disposed on opposite sides of the frame 10 and extend toward the direction of the lifting mechanism 20. The two conveyor belts are respectively disposed on opposite side walls of the two mounting structures 3121 and are located between the upper and lower sides of the mounting structures 3121. A limiting portion is formed between the conveyor belts and the upper side of the mounting structures 3121.

[0053] 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.

[0054] In some embodiments, the two mounting structures 3121 are detachably configured so that the distance between them is adjustable. Specifically, since the PCB boards have different sizes, the detachable configuration of the two mounting structures 3121 allows for adjustable spacing, enabling the spacing to be adjusted according to the size of the PCB board. This improves the practicality of the PCB board mounting mechanism. Of course, in other embodiments, the two mounting structures 3121 are fixedly mounted to the frame 10.

[0055] 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.

[0056] 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 material frame due to the excessive distance between the material frame and the feeding mechanism 30.

[0057] Furthermore, the inner wall of the conveying component 22 near the feeding mechanism 30 is provided with a protruding stop 221, which is spaced apart from the surface of the conveying component 22.

[0058] Specifically, the stop portion 221 is used to limit the material frame and prevent it from sliding out from 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 221. Alternatively, the inner wall of the conveying component 22 near the feeding mechanism 30 is provided with a protruding stop portion 221, and the inner wall of the opposite side of the stop portion 221 extends and is spaced apart from the surface of the conveying component.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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 connecting plate 44, on which the driving assembly 411 and the pushing assembly 412 are both mounted. The connecting 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.

[0072] Specifically, the connecting 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 connecting plate 44. This allows the mounting beam 43 of the connecting plate 44 to move along its length. After adjustment, the position can be fixed by tightening screws, ensuring that the pushing component 412 abuts against the middle of the PCB board during movement. This improves the stability of pushing the PCB board. Of course, in other embodiments, the connecting plate 44 is fixedly mounted on the mounting beam 43.

[0073] 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 41 to descend to the pushing position and move toward the lifting mechanism 20 when it receives the electrical signal from the sensor.

[0074] 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.

[0075] 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.
