[0031] The utility model provides a kind of PCB board machine.

[0032] In the embodiments of the utility model, as shown in the drawings, Figures 1 to 5 The PCB board machine includes rack 10, lifting mechanism 20, pushing mechanism 30 and material receiving mechanism 40.

[0033] Specifically, the lifting mechanism 20 is arranged on the rack 10 in a lifting manner, the lifting mechanism 20 is provided with a placing position for placing the material frame, the lifting mechanism 20 has an upper receiving position and a lower discharging position arranged in sequence, the lifting mechanism 20 receives the material frame in the receiving position, and transfers the material frame when the lifting mechanism 20 is in the discharging position. The receiving position can be arranged below the discharging position, or arranged above the discharging position.

[0034] Specifically, in some embodiments, the receiving position is arranged below the discharging position. That is, the lifting mechanism 20 is in a low position to receive the material frame loaded with the PCB, and after receiving the material frame, the lifting mechanism 20 moves towards the discharging position.

[0035] In another embodiment, the receiving position is arranged above the discharging position. That is, the lifting mechanism 20 is in a high position to receive the material frame loaded with the PCB, and after receiving the material frame, the lifting mechanism 20 moves towards the discharging position. The arrangement can be set according to actual conditions, which is not limited in the present application.

[0036] The pushing mechanism 30 is arranged on one side of the lifting mechanism 20, the pushing mechanism 30 has a pushing piece extending towards the lifting mechanism 20, the pushing piece is used to push the PCB in the material frame out of the other side of the lifting mechanism 20. Specifically, when the lifting mechanism 20 moves from the receiving position to the discharging position while carrying the material frame, the lifting mechanism 20 will pause for a certain time after moving a certain distance towards the discharging position, so that the pushing piece can push the PCB at this position out of the other side of the lifting mechanism 20 in the material frame.

[0037] The distance of the lifting mechanism 20 moving towards the discharging position each time is set according to the distance between the adjacent two PCBs in the material frame, so that the lifting mechanism 20 can move the adjacent two PCBs to the pushing axis of the pushing piece each time. The pausing time of the lifting mechanism 20 can be set according to the pushing time of the pushing piece. For example, the pausing time of the lifting mechanism 20 can be five seconds, six seconds, seven seconds, etc. The arrangement can be set according to actual conditions.

[0038] In the embodiment, the PCB loading machine further comprises a control module, the control module is in control connection with the lifting mechanism 20 and the pushing mechanism 30, and is used to control the lifting mechanism 20 and the pushing mechanism 30 according to the set parameters.

[0039] The receiving mechanism 40 is arranged on the other side of the lifting mechanism 20, and is used to receive the PCB pushed by the pushing member and to transport the PCB. The transport direction of the receiving mechanism 40 intersects with the extension direction of the pushing member. That is, the receiving mechanism 40 and the pushing mechanism 30 are arranged on opposite sides of the lifting mechanism 20. When the pushing member pushes the PCB in the material frame out, the PCB can be received by the receiving mechanism 40, and the receiving mechanism 40 transports the PCB to the next processing device. The transport direction of the receiving mechanism 40 intersects with the extension direction of the pushing member, that is, the transport direction of the receiving mechanism 40 points to the side of the rack 10, that is, the subsequent processing device of the PCB is arranged on the side of the PCB boarder.

[0040] The lifting mechanism 20 is arranged on the rack 10, and has a placing position, a receiving position and a discharging position. The lifting mechanism 20 receives the material frame in the receiving position, and moves from the receiving position to the discharging position in the state of carrying the material frame. The pushing mechanism 30 is arranged on one side of the lifting mechanism 20, and has a pushing member extending towards the lifting mechanism 20. The pushing member is used to push the PCB in the material frame to the other side of the lifting mechanism 20. The receiving mechanism 40 is arranged on the other side of the lifting mechanism 20, and is used to receive the PCB pushed by the pushing member and to transport the PCB. The transport direction of the receiving mechanism 40 intersects with the extension direction of the pushing member. In this way, the receiving mechanism 40 receives the PCB pushed by the pushing member, and transports the received PCB. The transport direction of the receiving mechanism 40 intersects with the direction of the pushing member, that is, the receiving mechanism 40 transports towards the side of the rack 10. In this way, the subsequent processing device of the PCB can be arranged on the side of the PCB boarder. Compared with the conventional way of arranging the subsequent processing device of the PCB on the tail end of the PCB boarder, the length of the overall production system of the PCB can be reduced.

[0041] In some embodiments, the receiving mechanism 40 is rotatably arranged on the rack 10, and has a feeding component 41. The feeding component 41 is used to receive the PCB pushed by the pushing mechanism 30. The feeding component 41 has a first state and a second state. In the first state, the transport direction of the feeding component 41 is parallel to the extension direction of the pushing member. In the second state, the transport direction of the feeding component 41 intersects with the extension direction of the pushing member. The feeding component 41 is configured to start working when the pushing member pushes the PCB, and to stop working after receiving the PCB.

[0042] Specifically, the feeding component 41 is in the first state for receiving the PCB pushed by the pushing piece, and rotates to the second state after receiving the PCB, so that the feeding component 41 in the second state delivers the PCB to the next processing equipment. Wherein, when the feeding component 41 receives the PCB in the first state, the feeding component 41 is in the running state, so that when the PCB contacts the feeding component 41, the friction between the PCB and the feeding component 41 caused by the pushing of the pushing piece can be avoided, that is, the production yield of the PCB is improved. Of course, in other embodiments, the receiving mechanism 40 is fixedly installed on the rack 10.

[0043] In some embodiments, the receiving mechanism 40 includes a rotating component 42, a mounting plate 43, and a plurality of auxiliary wheels 44. The rotating component 42 is installed on the mounting plate 43 and is in transmission connection with the feeding component 41. The mounting plate 43 is installed on the rack 10 and is spaced from the feeding component 41. The plurality of auxiliary wheels 44 are arranged between the mounting plate 43 and the feeding component 41 and are distributed along the circumferential direction of the rotating axis of the rotating component 42.

[0044] Specifically, the number of auxiliary wheels 44 is at least two. The rotating component 42 is used to drive the feeding component 41 to rotate. When the rotating component 42 drives the feeding component 41 to rotate, the plurality of auxiliary wheels 44 can provide an auxiliary effect, so that the rotation of the feeding component 41 is more smooth, and the rotation smoothness of the feeding component 41 is improved. Wherein, the plurality of auxiliary wheels 44 can be installed on the mounting plate 43 or the feeding component 41. For example, the number of auxiliary wheels 44 can be two, three, four, etc., but is not limited to. Of course, in other embodiments, the receiving mechanism 40 can also not be provided with auxiliary wheels 44.

[0045] In some embodiments, the feeding component 41 includes a mounting seat 411 and a feeding assembly 412. The plurality of auxiliary wheels 44 are arranged between the mounting seat 411 and the mounting plate 43. The rotating component 42 is in transmission connection with the mounting seat 411. The feeding assembly 412 is slidingly installed on the mounting seat 411. The feeding assembly 412 has a first state and a second state.

[0046] Specifically, when the feeding assembly 412 is in the first state, the feeding assembly 412 can slide towards the lifting mechanism 20. When the feeding assembly 412 is in the second state, the feeding assembly 412 can slide towards the lateral direction of the rack 10. In this way, when the feeding assembly 412 is in the first state, the feeding assembly 412 slides towards the lifting mechanism 20 to shorten the distance between the lifting mechanism 20, so as to facilitate receiving the PCB pushed by the pushing piece. When the feeding assembly 412 is in the second state, the feeding assembly 412 slides towards the lateral direction of the rack 10 to shorten the distance between the next processing equipment, so as to facilitate delivering the PCB to the next processing equipment.

[0047] Further, one of the mounting seat 411 and the feeding assembly 412 is provided with a sliding rail 45, and the other is provided with a sliding block 46, the sliding block 46 is slidingly installed on the sliding rail 45, the sliding rail 45 extends along the sliding direction of the feeding assembly 412, and the feeding assembly 41 further includes a driving member 70, which is installed on the mounting seat 411 and is in transmission connection with the feeding assembly 41, so as to drive the feeding assembly 41 to slide.

[0048] In some embodiments, the PCB plate loading machine further includes a feeding mechanism 50, which is located on the same side of the pushing mechanism 30 as the lifting mechanism 20, and is used to convey the material frame. When the material receiving position, the lifting mechanism 20 corresponds to the feeding mechanism 50.

[0049] Specifically, the material frame is conveyed by the feeding mechanism 50, which can realize the mechanical automation of the PCB plate loading machine and reduce labor costs. Of course, in other embodiments, the PCB plate loading machine does not have the feeding mechanism 50.

[0050] In some embodiments, the PCB plate loading machine includes two feeding mechanisms 50, which are located on the same side of the pushing mechanism 30 as the lifting mechanism 20, and are arranged in an upper and lower interval. When the material receiving position, one of the feeding mechanisms 50 corresponds to the lifting mechanism 20, and is used to convey the material frame to the lifting mechanism 20. When the material discharging position, the other feeding mechanism 50 corresponds to the lifting mechanism 20, and is used to send the empty material frame away.

[0051] In order to facilitate understanding of the scheme, it is assumed that the two feeding mechanisms 50 are a first feeding mechanism and a second feeding mechanism, and the first feeding mechanism is located below the second feeding mechanism.

[0052] Specifically, when the material receiving position is below the material discharging position, the lifting mechanism 20 corresponds to the first feeding mechanism to receive the material frame conveyed by the first feeding mechanism, and moves upward after receiving the material frame. When the lifting mechanism 20 corresponds to the second feeding mechanism, the lifting mechanism 20 is located at the material discharging position, at which time the PCB plate in the material frame is pushed out, i.e., the user can take the material frame away from the placing position, or send the material frame away through the second feeding mechanism. After the material frame is taken away, the lifting mechanism 20 returns to the material receiving position and repeats the above steps.

[0053] When the receiving position is above the discharging position, i.e. the lifting mechanism 20 corresponds to the second feeding mechanism, the lifting mechanism 20 receives the frame conveyed by the second feeding mechanism and moves downward after receiving the frame. When the lifting mechanism 20 corresponds to the first feeding mechanism, the lifting mechanism 20 is located at the discharging position, at which time the PCB board in the frame is pushed out, i.e. the user can take the frame away from the placing position or send the frame away through the first feeding mechanism. After the frame is taken away, the lifting mechanism 20 returns to the receiving position and repeats the above steps.

[0054] In this way, the lifting mechanism 20 can receive the frame through one of the feeding mechanisms 50. When one of the feeding mechanisms 50 fails, the other feeding mechanism 50 can be used for feeding without affecting production. Of course, in other embodiments, the PCB board placing machine can be provided with only one feeding mechanism 50.

[0055] In some embodiments, the lifting mechanism 20 includes a lifting component 21 and a conveying component 22. The lifting component 21 is installed on the rack 10 and is in transmission connection with the conveying component 22. The lifting component 21 is used to drive the conveying component 22 to lift. The conveying component 22 is provided with a placing position. The conveying direction of the conveying component 22 is parallel to the extension direction of the pushing piece.

[0056] Specifically, when the feeding mechanism 50 conveys the frame to the placing position on the conveying component 22, the conveying component 22 can drive the frame to move towards the receiving mechanism 40 to shorten the distance between the frame and the receiving mechanism 40, so as to prevent the distance between the frame and the receiving mechanism 40 from being too large to cause the PCB board to be unable to be pushed to the receiving mechanism 40.

[0057] In some embodiments, the inner wall of one end of the conveying component 22 close to the receiving mechanism 40 is provided with a protruding stop portion 221 which is spaced from the surface of the conveying component 22. Specifically, the stop portion 221 is used to limit the position of the frame to prevent the frame from sliding out of the one end of the conveying component 22 close to the receiving mechanism 40. Alternatively, the inner walls of both ends of the conveying component 22 close to the receiving mechanism 40 are provided with protruding stop portions 221. Or, the inner wall of one end of the conveying component 22 close to the receiving mechanism 40 is provided with a protruding stop portion 221, and the inner wall opposite to the stop portion 221 extends and is spaced from the surface of the conveying component 22.

[0058] In some embodiments, the feeding mechanism 50 is provided with limiting pieces 53 protruding upward on opposite sides. Specifically, the limiting pieces 53 are used to limit the position of the frame to prevent deviation of the frame when placed, which affects the subsequent pushing of the PCB board by the pushing piece, i.e. which is conducive to improving the pushing smoothness of the pushing piece. Of course, in other embodiments, the feeding mechanism 50 can also not be provided with the limiting pieces 53.

[0059] In some embodiments, the feeding mechanism 50 comprises two mounting structures 51 and two conveying belts 52, the two mounting structures 51 are detachably mounted on the rack 10, so that the spacing between the two mounting structures 51 is adjustable, the outer side wall of each of the two mounting structures 51 is provided with a limiting piece 53, and the two conveying belts 52 are mounted in one-to-one correspondence with the two mounting structures 51. Specifically, the PCB boards have different sizes, and the PCB boards of different sizes need to be correspondingly used with the adaptive material frames. The two mounting structures 51 are detachably arranged, so that the spacing between the two mounting structures 51 is adjustable. In this way, the spacing between the two mounting structures 51 can be adjusted according to the size of the material frame, so that the limiting of the material frame of different sizes can be realized. It is beneficial to improve the practicability of the PCB board feeding machine. Of course, in other embodiments, the two mounting structures 51 are fixedly mounted on the rack 10.

[0060] In some embodiments, the PCB board feeding machine further comprises a scanning mechanism 60, the scanning mechanism 60 is mounted on the rack 10, and the scanning side of the scanning mechanism 60 faces the placing position. Specifically, the scanning mechanism 60 is used for scanning the material frame on the placing position and uploading the system to register the information of the material frame. Of course, in other embodiments, the PCB board feeding machine does not arrange the scanning mechanism 60.

[0061] The above description is only the preferred embodiments of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields under the inventive concept of the present application is included in the patent protection range of the present application.
