Description

Technical Field

[0001] This utility model relates to the technical field of plate feeding machines, and specifically to a plate pushing mechanism of a plate receiving machine. Background Technology

[0002] The board receiving machine is one of the most commonly used automated equipment on the PCB production line. Currently, the standard board pushing mechanism can only push bare boards or PCB boards with components no more than 20mm high. Boards higher than 30mm cannot be used. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pusher mechanism for a board receiving machine, which solves the problem of pushing PCB boards with components larger than 30mm. The first and second transmission guides are raised by the moving rail seat and the fixed rail seat to create a pushing space suitable for PCB boards with components larger than 30mm. The pushing part is then pushed upward by the lifting cylinder, and the pushing part is pulled by the transmission motor as the power source. The pushing part of the pusher assembly moves forward by the cooperation of the slide rail and the slider to push the PCB board with components larger than 30mm into the material frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pusher mechanism for a board collecting machine includes a frame. The pusher mechanism further includes a support frame disposed on one side of the frame, a mounting assembly disposed above the support frame, a pusher assembly disposed above the mounting assembly and connected to it via a connecting plate, and a power assembly disposed below the connecting plate. The power assembly provides a driving force for horizontal movement of the pusher assembly, which pushes the PCB board into a collection frame. The mounting assembly is used to mount the pusher assembly.

[0006] The mounting assembly includes at least two lead screw mounting portions located on both sides above the support frame, at least three threaded lead screws passing through the lead screw mounting portions, and at least two optical shafts located between the threaded lead screws. The optical shafts are slidably connected to the connecting plate through the lead screw mounting portions.

[0007] A first transmission guide rail is provided on one side of the lead screw mounting part. At least one movable rail seat is provided at the bottom of the first transmission guide rail. The movable rail seat is slidably connected to the lead screw through a threaded connector. The movable rail seat is slidably connected to the optical shaft through a flange bearing. A second transmission guide rail is provided on the other side of the lead screw mounting part. At least one fixed rail seat is provided at the bottom of the second transmission guide rail. The fixed rail seat is fixedly connected to the optical shaft.

[0008] The power assembly includes a transmission motor located below the connecting plate, a motor wheel located at one end of the transmission motor, and a transmission belt sleeved on the motor wheel. The transmission motor is fixedly connected to the lower part of the connecting plate through a motor plate.

[0009] The pusher assembly includes mounting blocks at both ends of the connecting plate and a sensor on one side of the mounting block, which is used to sense the running trajectory of the pusher assembly.

[0010] The pusher assembly also includes a guide rail disposed on the upper surface of the connecting plate, on which a slider is slidably connected.

[0011] The pusher assembly also includes a pusher mounting plate disposed on the upper surface of the slider, two vertical optical axes passing through the pusher mounting plate, a pushing part disposed at one end of the vertical optical axes, and a pressure block disposed on one side of the pusher mounting plate, the pressure block being fixedly connected to the transmission belt.

[0012] At least one roller is provided on the side of one end of the vertical optical axis, which is used to make the push plate assembly slide and connect with the connecting plate.

[0013] The push plate assembly includes a lifting cylinder that passes through the bottom surface of the connecting plate. One end of the lifting cylinder is connected to a cylinder clamping block, and one side of the cylinder clamping block is fixedly connected to the connecting plate. The cylinder clamping block is used to fix the lifting cylinder.

[0014] The lifting cylinder has a lifting rod at one end, and a buffer part at the end of the lifting rod. The buffer part is used to buffer the interaction force when the lifting rod lifts and pushes the part. The lifting cylinder is used to drive the lifting rod to lift and push the part.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The cooperation of the lead screw mounting part, the threaded lead screw and the optical axis ensures the stability and accuracy of the pusher assembly during movement. The threaded lead screw plays a guiding role, while the optical axis plays a supporting role, enabling the pusher assembly to push the PCB board smoothly and accurately.

[0017] 2. The moving rail seat and the fixed rail seat raise the first and second transmission rails, which are suitable for pushing PCB boards with components higher than 30mm. The power component efficiently transmits power to the pusher assembly through the cooperation of the transmission motor, motor wheel and transmission belt, which simplifies the power transmission path and enables the pusher assembly to complete the push more quickly.

[0018] 3. The sensor setup enables the control terminal to monitor the position and status of the pusher assembly in real time, thereby achieving precise control of the pushing process, avoiding errors and collisions during the pushing process, and improving the reliability and safety of the equipment.

[0019] 4. Through the cooperation of the lifting cylinder and the lifting rod, the pushing part has a lifting adjustment function, which enables the pushing mechanism to adapt to PCB boards of different heights, thus improving the versatility and adaptability of the equipment.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figure 1-7 As shown, this utility model relates to a pusher mechanism for a board collecting machine, including a frame 1, a support frame 3 disposed on one side of the frame 1, a mounting assembly 4 disposed above the support frame 3, a pusher assembly 6 disposed above the mounting assembly 4 and connected by a connecting plate 40, and a power assembly 5 disposed below the connecting plate. The power assembly 5 is used to provide a driving force for the horizontal movement of the pusher assembly 6. The pusher assembly 6 is used to push the PCB board into the collection frame 2. The mounting assembly 4 is used to mount the pusher assembly 6.

[0031] like Figure 1-3As shown, the mounting assembly 4 includes two lead screw mounting portions 41 each located on both sides above the support frame 3, at least three threaded lead screws 42 passing through the lower part of the lead screw mounting portion 41, and at least two optical shafts 43 located between the threaded lead screws 42. The optical shafts 43 are slidably connected to the connecting plate 40 through the lead screw mounting portions 41. A first transmission guide rail 44 is mounted on one side of the lead screw mounting portion 41. At least one movable rail seat 45 is mounted on the bottom of the first transmission guide rail 44. The movable rail seat 45 is slidably connected to the threaded lead screw 42 through a threaded connector 46. The movable rail seat 45 is slidably connected to the optical shaft 43 through a flange bearing 47. A second transmission guide rail 48 is provided on the other side of the lead screw mounting portion 41. Two fixed rail seats 49 are provided at the bottom of the second transmission guide rail 48. The fixed rail seats 49 are fixedly connected to the optical shaft 43.

[0032] like Figure 2-3 As shown, preferably, three sets of threaded screws 42 are selected. These three sets of threaded screws 42 are on the same horizontal plane and are respectively installed at the front, middle and rear ends of the screw mounting part 41. The cooperation between the three sets of threaded screws 42 and the threaded connectors 46 is conducive to the smooth adjustment of the displacement of the moving rail seat 45. When the threaded screws 42 rotate, the threaded connectors are displaced through the threads between the threaded screws 42 and the threaded connectors 46, thereby causing the threaded connectors 46 to move along the setting direction of the threaded screws 42, so that the distance between the moving rail seat 45 and the fixed rail seat 49 matches the width of the PCB board. Two sets of optical axes 43 are selected. The main function of the optical axes is to support the stability of the moving rail seat 45 and the fixed rail seat 49. The optical axes 43 are connected to the connecting plate 40 in the vertical direction. The push plate assembly 6 is connected to one side of the connecting plate 40.

[0033] like Figure 3 As shown, a bearing 4a is further connected between the threaded screw 42 and the screw mounting part 41. The bearing 4a is used to adjust the displacement of the moving rail seat 45 by rotating the threaded screw 42. The optical shaft 43 is fixedly connected to the screw mounting part 41. One end of the optical shaft 43 and the threaded screw 42 are together mounted on the moving rail seat 45.

[0034] like Figure 4 As shown, the power assembly 5 includes a transmission motor 50 located below the connecting plate 40, a motor wheel 51 located at one end of the transmission motor 50, and a transmission belt 52 sleeved on the motor wheel 51. The transmission motor 50 is fixedly connected to the lower part of the connecting plate 40 through a motor plate 53.

[0035] like Figure 2-4As shown, the pusher assembly 6 includes mounting blocks 60 at both ends of the connecting plate 40, a sensor 61 on one side of the mounting block 60, a guide rail 62 on the upper surface of the connecting plate 40 and a slider 63 slidably connected to the guide rail 62, a pusher mounting plate 64 on the upper surface of the slider 63, two vertical optical axes 65 passing through the pusher mounting plate 64, a pushing part 66 at one end of the vertical optical axes 65, a pressure block 67 on one side of the pusher mounting plate 64, and a lifting cylinder 68 passing through the bottom surface of the connecting plate 40. The pressure block 67 is fixedly connected to the transmission belt 52, and the sides of one end of the vertical optical axes 65 are respectively... At least one roller 69 is provided, which is used to slide the push plate assembly 6 and the connecting plate 40. One end of the lifting cylinder 68 is connected to the cylinder clamp 6a, and one side of the cylinder clamp 6a is fixedly connected to the connecting plate 40. The cylinder clamp 6a is used to fix the lifting cylinder 68. One end of the lifting cylinder 68 is connected to a lifting rod 6b, and the end of the lifting rod 6b is connected to a buffer part 6c. The buffer part 6c is used to buffer the interaction force when the lifting rod 6b lifts the pushing part 66. The lifting cylinder 68 is used to drive the lifting rod 6b to lift the pushing part 66. The sensor 61 is used to sense the running trajectory of the push plate assembly 6.

[0036] like Figure 4 As shown, the working state of sensor 61 is as follows: when the push plate assembly 6 connected to slider 63 moves to one end of guide rail 62, the front sensing plate on the push plate assembly 6 contacts sensor 61 and sends a signal to the control terminal. The control terminal receives and processes the signal, and the transmission motor 50 works to reset the push plate assembly. After the push plate assembly returns to the other end of the guide rail, the rear sensing plate on the push plate assembly contacts sensor and sends a signal to the control terminal. The control terminal receives and processes the signal.

[0037] like Figure 1 , 5As shown, further, a material frame transfer mechanism 7 is provided on one side of the frame 1. The material frame transfer mechanism 7 is used to transport the collection frame. The material frame transfer mechanism 7 includes a first transfer component 70 disposed on the same plane as the first transmission guide rail 44 and a second transfer component 71 disposed below the first transfer component 70. The first transfer component 70 and the second transfer component 71 are fixedly connected to one side of the frame 1 through a mounting bracket 700. The first transfer component 70 is used to output the collection frame, and the second transfer component 71 is used to input the collection frame. The first transfer component 70 includes a part disposed on the upper part of the mounting bracket 700. The assembly includes a first main transmission shaft 701, two first transmission gears 702 mounted on the first main transmission shaft 701, two first auxiliary gears 703 mounted on one side of the first main transmission shaft 701, and a first drive motor 704 positioned between the first main transmission shaft 701 and the first auxiliary gears 703. The first drive motor 704 is rotatably connected to the first main transmission shaft 701. Here, the motor's first transmission gear 705 meshes with a first mating gear 706 mounted on the first main transmission shaft 701. When the collection frame enters the first transfer assembly 70, the bottom of the collection frame contacts the first transmission gears. Wheel 702, the first drive motor 704 causes the first main transmission shaft 701 to rotate synchronously through the meshing of the first transmission gear 705 and the first mating gear 706, the first main transmission shaft 701 synchronously drives the first transmission gear 702 to rotate, thereby transferring the collection frame; the second transfer assembly 71 includes a second main transmission shaft 710 located at the lower part of the mounting bracket 700, two second transmission gears 711 located on the second main transmission shaft 710, two second auxiliary gears 712 located on one side of the second main transmission shaft 710, and a second auxiliary gear 712 located between the second main transmission shaft 710 and the second auxiliary gear 712. The second drive motor 713 is rotatably connected to the second main transmission shaft 710. Here, the second transmission gear 714 of the motor meshes with the second mating gear 715 provided on the second main transmission shaft 710. When the collection frame enters the second transfer assembly 71, the bottom of the collection frame contacts the second transmission gear 711. The second drive motor 713 causes the second main transmission shaft 710 to rotate synchronously through the meshing of the second transmission gear 714 and the second mating gear 715. The second main transmission shaft 710 synchronously drives the second transmission gear 711 to rotate, thereby transferring the collection frame.

[0038] like Figure 1 , 6As shown in Figure 7, furthermore, a lifting mechanism 8 is provided inside the frame 1. This lifting mechanism 8 is used to cooperate with the pusher assembly 6 to load the sheet metal. The lifting mechanism 8 includes a lifting component 80 located on one side of the frame 1, a support component 81 located on one side of the lifting component 80, and a third transfer component 82 located at the bottom of the support component 81. The lifting component 80 is used to cooperate with the pusher assembly 6 to lift the collection frame to collect the sheet metal. The support component 81 is used to support and fix the collection frame. The third transfer component 82 is used to transfer the collection frame. The lifting component 80 includes two fixed shafts 800 located inside the frame 1 and a transmission shaft 80 located between the two fixed shafts 800. 1. A drive motor 802 is located on one side of the drive shaft 801. The drive motor 802 is fixedly connected to the frame 1. The drive shaft 801 is rotatably connected to the drive motor 802. Both ends of the drive shaft 801 are rotatably connected to the frame 1. The support assembly 81 includes a fixed frame 810 located on one side of the fixed shaft 800 and four clamping members 811 located on one side of the fixed frame 810. The fixed frame 810 is slidably connected to two fixed shafts 800 respectively through sliding bushings 812. The fixed frame 810 is rotatably connected to the drive shaft 801 through a coupling 813. The third transfer assembly 82 includes a third main transmission shaft located at the bottom of the fixed frame 810. 820, two third transmission gears 821 mounted on the third main transmission shaft 820, two third auxiliary gears 822 mounted on one side of the third main transmission shaft 820, and a third drive motor 823 located between the third main transmission shaft 820 and the third auxiliary gears 822. The third drive motor 823 is rotatably connected to the third main transmission shaft 820. Here, the motor's third transmission gear 824 meshes with a third mating gear 825 mounted on the third main transmission shaft 820. When the collection frame enters the third transfer assembly 82, the bottom of the collection frame contacts the third transmission gear 821, and the third drive motor 823 rotates through the third transmission gear 821. The meshing of the four wheels with the third gear 825 causes the third main transmission shaft 820 to rotate synchronously. The third main transmission shaft 820 synchronously drives the third transmission gear 821 to rotate, causing the collection frame to transfer. When the collection frame enters the fixed frame, the collection frame is fixed by the clamping member 811. The transmission motor 802 drives the transmission shaft 801 to rotate. The fixed frame 810 slides along the fixed shaft 800 through the coupling 813. After the collection frame is full, the fixed frame 810 is lifted to the upper part of the frame 1. The clamping member 811 releases the collection frame. The third transfer component 82 transfers the collection frame to the first transfer component 70. The first transfer component 70 transfers the collection frame out of the working position.

[0039] Working principle: First, based on the width of the PCB board, the distance between the first transmission guide rail 44 and the second transmission guide rail 48 is adjusted via the threaded screw 42 to accommodate the width of the PCB board. Second, when the sensor 61 at one end of the pusher assembly 6 senses the board's arrival signal, the lifting cylinder 68 operates, causing the lifting rod 6b to rise, thus lifting the pushing part 66 of the pusher assembly 6 to the pushing position. The lifting cylinder 68 then stops operating. Simultaneously, the empty material collection frame 2 is lifted to the pushing position via the lifting mechanism within the frame 1. This lifting mechanism works in conjunction with the pusher assembly 6. Each time the pusher assembly 6 pushes a board, it lifts... The lifting mechanism rises synchronously to one station until the collection box 2 is full. At this time, the transmission motor 50 starts to work, and drives the push plate mounting plate 64 of the push plate assembly 6 to move along the guide rail 62 through the transmission belt 52 on the motor wheel 51. This causes the pushing part 66 to push the PCB board forward along the first transmission guide rail 44 and the second transmission guide rail 48, and push the PCB board into the collection box 2. Then, the rear sensor on the push plate assembly contacts the sensor and sends a signal to the control terminal. The control terminal receives and processes the signal, and the transmission motor 50 reverses to reset the push plate assembly 6 and start the next work cycle.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
