Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated unloading equipment technology, and in particular to an automatic unloading device. Background Technology
[0002] Some electronic components need to be placed in trays during processing and moved to various processing equipment via tracks. After processing, the trays need to be transferred to the hopper via a unloading machine. The existing unloading machine uses a belt conveyor to transport the trays to the hopper. When the trays partially enter the hopper, the reduced contact area with the belt leads to decreased friction, making it difficult for them to enter the hopper stably. Utility Model Content
[0003] To address the problems in the prior art, this utility model provides an automatic unloading device that pushes the tray into the hopper via a pusher mechanism, thereby improving the stability of the tray entering the hopper.
[0004] This utility model is achieved through the following technical solution:
[0005] An automatic unloading device includes an unloading frame, and a hopper lifting device is provided on one side of the unloading frame. The hopper lifting device is used to place the hopper and control the height of the hopper in the unloading frame.
[0006] The material tray conveying mechanism includes a first conveying track that docks with the lower plate frame, the first conveying track being used to convey material trays to the hopper in the lower plate frame;
[0007] The pusher mechanism includes a push rod, a drive mechanism for driving the push rod to move along a first conveying track, and a control mechanism for controlling the top end of the push rod to rise or fall. The first conveying track includes two guide rails, and the pusher mechanism is disposed between the two guide rails and below the guide rails. When the top end of the push rod rises, the top end of the push rod is at the same height as the material tray, which is used to push the material tray to move into the hopper. When the top end of the push rod falls, the push rod is below the height of the guide rails.
[0008] Furthermore, the push rod is hinged to a push rod bracket via a pivot, and a thrust spring is installed between the push rod and the push rod bracket to keep the top of the push rod in an upward-raised state.
[0009] Furthermore, it also includes a guide rail arranged parallel to the guide rail, the guide rail being equidistant from the two guide rails, and the push rod bracket being slidably mounted on the guide rail via a slider.
[0010] Furthermore, the control mechanism includes a top block disposed at the end of the guide rail and a top plate mounted at the end of the push rod. The tail of the top plate has an upward-curving arc. A roller is mounted on the top of the top block to cooperate with the top plate to lift the end of the push rod, causing the top of the push rod to move downward.
[0011] Furthermore, when the top plate is lifted by the rollers, the highest point of the top plate is lower than the height of the guide rail; the top end face of the push rod has a preset tilt angle, and when the top end of the push rod is lifted, the top end face is parallel to the contact surface of the material tray.
[0012] Furthermore, the drive mechanism includes a transmission belt that horizontally surrounds the guide rail, a fixing block that is fixedly connected to the transmission belt on one side of the push rod bracket, and pulleys that are mounted on both ends of the transmission belt, one of which is driven by a push rod motor.
[0013] Furthermore, the hopper lifting device includes a lifting platform, a lifting bracket, a guide column and a screw and nut mechanism installed in the lifting bracket, and a lifting motor that drives the screw and nut mechanism to move; the main body of the lifting platform extends into the lower plate frame, and the side of the lifting platform is set in the lifting bracket and connected to the guide column and the screw and nut mechanism.
[0014] Furthermore, a moving belt and a positioning mechanism that cooperate with the moving belt are arranged on the lifting platform. The conveying direction of the moving belt is the same as the conveying direction of the first conveying track.
[0015] Furthermore, a first side clamping mechanism is installed on one side of the gantry support, and a gantry support is set above the moving belt to clamp the upper end of the hopper; a second side clamping mechanism is installed on one side of the moving belt to clamp the bottom of the hopper; the moving belt includes two tracks, and a positioning plate is set between the two tracks.
[0016] Furthermore, it also includes a hopper support, which is set on one side of the lower plate frame and includes upper and lower layers. Both upper and lower layers are equipped with belt conveyor mechanisms, which are used to connect with the hopper lifting device.
[0017] The beneficial effects of this utility model are: by setting the push plate mechanism between the two guide rails of the first conveying track, the material tray can be stably pushed from the first conveying track into the hopper through the push plate mechanism, and the top of the push rod can be lowered through the control mechanism, so that the material tray passes over the push rod without affecting the conveying of the material tray on the first conveying track, thereby improving the conveying stability of the material tray from the first conveying track to the hopper.

[0031] like Figure 1 The diagram shown is a structural schematic of an automatic unloading device in one embodiment of this application. The automatic unloading device provided in this embodiment includes an unloading frame 1. A hopper lifting device 2 is provided on one side of the unloading frame 1. The hopper lifting device 2 is used to place the hopper 3 and control the height of the hopper 3 in the unloading frame 1.
[0032] The lower frame 1 can be a frame structure, allowing the hopper 3 to enter and exit the lower frame 1 and to move vertically within it. The hopper 3 is typically a multi-layered hopper, a frame structure with an inlet and outlet at one end, with several layers of protrusions on opposite inner walls to support the material tray 5. The hopper lifting device 2 can include a lifting mechanism that moves the hopper 3 vertically within the lower frame 1 and controls the height of the hopper 3, allowing the material tray 5 to enter any layer within the hopper 3. The hopper lifting device 2 also includes a conveying mechanism, which can be any mechanism capable of enabling the hopper 3 to enter and exit the lower frame 1.
[0033] The automatic unloading device also includes a material tray conveying mechanism 4, which includes a first conveying track 41 that docks with the unloading frame 1. The first conveying track 41 is used to convey material trays 5 to the hopper 3 in the unloading frame 1.
[0034] The material tray conveying mechanism 4 can convey the material tray 5 from the previous step to the position of the lower plate frame 1, thereby further completing the lower plate step. A belt conveyor can be installed on the first conveying track 41. The material tray 5 is conveyed along the first conveying track 41 to the direction of the hopper 3 via the belt conveyor, and is further pushed into the hopper 3 by the push plate mechanism 6.
[0035] like Figure 2The diagram shows the installation of the push rod in this embodiment. The automatic unloading device also includes a push plate mechanism 6, which includes a push rod 7, a drive mechanism 61 for driving the push rod 7 to move along the first conveying track 41, and a control mechanism 62 for controlling the lifting or lowering of the top end of the push rod 7. The first conveying track 41 includes two guide rails, and the push plate mechanism 6 is disposed between the two guide rails and located below the guide rails. When the top end of the push rod 7 is lifted, the top end of the push rod 7 is at the same height as the material tray 5, which is used to push the material tray 5 to move into the hopper 3. When the top end of the push rod 7 is lowered, the push rod 7 is lower than the height of the guide rails.
[0036] The pusher mechanism 6 is positioned between two guide rails, enabling it to push the material tray 5 from the front, thus providing a more stable and smooth thrust and improving the conveying stability of the material tray 5 between the first conveying track 41 and the hopper 3. The drive mechanism 61 can be an electric cylinder or any other drive mechanism 61 capable of driving the push rod 7 to move linearly. The push rod 7 can be mounted on a bracket, allowing its top end to be raised and lowered, preventing it from obstructing the material tray 5 from passing over the first conveying track 41. The control mechanism 62 can be designed according to the structure of the push rod 7, and can be any control mechanism 62 capable of controlling the raising or lowering of the top end of the push rod 7, such as a control electric cylinder. In use, the control mechanism 62 first controls the top of the push rod 7 to fall, and the material tray 5 passes over the push rod 7 along the first conveying track 41. After docking with the hopper 3, the control mechanism 62 controls the top of the push rod 7 to rise, and the drive mechanism 61 drives the push rod 7 to move along the first conveying track 41, so that the top of the push rod 7 contacts the material tray 5 and pushes the material tray 5 into the hopper 3. After the material tray 5 has completely entered the hopper 3, the drive mechanism 61 controls the push rod 7 to return to its original position, and the control mechanism 62 controls the top of the push rod 7 to fall, waiting for the next material tray 5 to pass.
[0037] In this embodiment, the push plate mechanism 6 is set between the two guide rails of the first conveying track 41. The push plate mechanism 6 can stably push the material tray 5 from the first conveying track 41 into the hopper 3. The push rod 7 can be lowered by the control mechanism 62 so that the material tray 5 can pass over the push rod 7 without affecting the conveying of the material tray 5 by the first conveying track 41, thus improving the conveying stability of the material tray 5 from the first conveying track 41 to the hopper 3.
[0038] like Figure 3 As shown, this is a schematic diagram of the control mechanism in this embodiment. In this embodiment, the push rod 7 is hinged to a push rod bracket 72 via a rotating shaft 71. A thrust spring 73 is installed between the push rod 7 and the push rod bracket 72 to push the top of the push rod 7 to remain in an upward state.
[0039] In this embodiment, the top end of the push rod 7 faces the lower plate frame 1, and the thrust spring 73 can keep the top end of the push rod 7 in a raised state. The structure of this embodiment is simple and stable, and the drive mechanism 61 and the control mechanism 62 can be easily arranged. The drive mechanism 61 can directly drive the push rod bracket 72 to move, thereby driving the push rod 7 to move. The control mechanism 62 can push the tail of the push rod 7 to move upward or pull the top end of the push rod 7 downward to realize the function of controlling the push rod 7.
[0040] In this embodiment, the automatic unloading device also includes a guide rail 63 arranged parallel to the guide rails. The guide rail 63 is equidistant from the two guide rails, and the push rod bracket 72 is slidably mounted on the guide rail 63 via a slider.
[0041] The guide rail 63 is installed between the two guide rails of the first conveying rail 41 and is equidistant from both guide rails, enabling it to apply a pushing force to the material tray 5 from the center position, further improving the stability of the pushing force. The push rod bracket 72 slides on the guide rail 63 via a slider, which also improves the stable movement of the push rod 7 and prevents the push rod 7 from deviating.
[0042] like Figure 3 As shown, in this embodiment, the control mechanism 62 includes a top block 74 disposed at the end of the guide rail 63 and a top plate 75 disposed at the end of the push rod 7. The tail of the top plate 75 has an upward-curving arc. A roller 76 is mounted on the top of the top block 74 for cooperating with the top plate 75 to lift the end of the push rod 7, so that the top of the push rod 7 moves downward.
[0043] The control mechanism 62 is a top block 74 fixed to the end of the guide rail 63. It uses the lever principle to apply an upward thrust to the end of the push rod 7, causing the top of the push rod 7 to move downward. The top block 74 works in conjunction with the drive mechanism 61 to control the push rod 7. This structure is simple and stable, requires no power unit, reduces equipment costs, and improves operational stability. The curved top plate 75, in conjunction with the roller 76, prevents jamming, improves the control stability of the push rod 7, and reduces the occurrence of malfunctions.
[0044] In this embodiment, when the top plate 75 is lifted by the roller 76, the highest point of the top plate 75 is lower than the height of the guide rail; the top end face of the push rod 7 has a preset tilt angle, and when the top end of the push rod 7 is lifted, the top end face is parallel to the contact surface of the material tray 5.
[0045] In order for the material tray 5 to pass smoothly over the push rod 7, the entire push rod 7 needs to be positioned below the first conveying track 41 when its top end falls. Preferably, the structure can be designed according to the height of the hinge point of the push rod 7, the height of the top block 74, and the length of the push rod 7 to meet the above requirements. The portion of the push rod 7 from its top end to the pivot 71 can be a telescopic rod, thereby adjusting its length. Adjusting this length can control the height at which the top end of the push rod 7 is raised, ensuring that the top end of the push rod 7 is at an appropriate height when raised to further push the material tray 5. Furthermore, the length of the push rod 7 can be determined according to the distance the material tray 5 needs to be pushed, ensuring that the material tray 5 can enter the hopper 3. The inclination angle of the top end face of the push rod 7 can be designed according to the required lifting angle, so that the top end face of the push rod 7 can make close contact with the material tray 5, increasing the contact area and thus improving the stability of the pushing force.
[0046] like Figure 4 The diagram shown is a schematic diagram of the drive mechanism in this embodiment. In this embodiment, the drive mechanism 61 includes a transmission belt 64 that is horizontally wrapped around the guide rail 63. A fixing block 65 that is fixedly connected to the transmission belt 64 is provided on one side of the push rod bracket 72. The two ends of the transmission belt 64 are respectively mounted on pulleys, and one of the pulleys is driven by a push rod motor 66.
[0047] In this embodiment, the linear movement of the push rod 7 is achieved through a drive belt 64 and a guide rail 63. This not only reduces equipment and maintenance costs but also provides a longer stroke, ensuring that the material tray 5 moves into position and fully enters the hopper 3. Furthermore, the drive belt 64 can achieve higher operating speeds, improving unloading efficiency. The push rod bracket 72 clamps the drive belt 64 with a fixing block 65. The drive belt 64 horizontally wraps around the guide rail 63 and connects to the push rod bracket 72 from the side, without increasing the height of the push rod 7. This allows for full utilization of space and a reasonable arrangement of the push rod 7's position, facilitating the pushing of the material tray 5 without hindering its passage.
[0048] like Figure 5 The diagram shown is a structural schematic of the silo lifting device in this embodiment. In this embodiment, the silo lifting device 2 includes a lifting platform 21, a lifting bracket 22, a guide column 23 and a screw nut mechanism 24 installed in the lifting bracket 22, and a lifting motor 25 that drives the screw nut mechanism 24 to move. The main body of the lifting platform 21 extends into the lower plate frame 1, and the side of the lifting platform 21 is arranged in the lifting bracket 22 and connected to the guide column 23 and the screw nut mechanism 24.
[0049] The lifting bracket 22 can be fixedly connected to the lower plate frame 1 to improve the overall stability of the automatic unloading device. The lifting platform 21 is controlled by the screw and nut mechanism 24, which has higher positioning accuracy in the vertical direction. With the help of photoelectric sensors, the height of the hopper 3 on the lifting platform 21 can be precisely controlled to rise or fall one layer of material tray 5 each time.
[0050] Preferably, there are two guide columns 23, which are set on one side of the lower plate frame 1, and a triangular support plate is set at the bottom of the lifting platform 21. The screw and nut mechanism 24 is set between the two guide columns 23.
[0051] Among them, the two guide columns 23 and the triangular support plate can stably support the lifting platform 21, and setting the guide columns 23 on one side of the lower plate frame 1 can reduce the overall space occupied by the automatic lower plate device, making it easy to set the two lower plate frames 1 side by side to realize double-rail lowering or simultaneous upper and lower plate processes.
[0052] like Figure 6 The diagram shown is an installation schematic of the lifting platform in this embodiment. In this embodiment, a movable belt 26 and a positioning mechanism 27 that cooperate with the movable belt 26 are arranged on the lifting platform 21. The conveying direction of the movable belt 26 is the same as the conveying direction of the first conveying track 41.
[0053] A movable belt 26 is installed on the lifting platform 21. The movable belt 26 can be equipped with a track and is controlled by a forward and reverse motor, enabling the hopper 3 to automatically enter or exit the lifting platform 21, improving the overall automation level of the equipment and facilitating control. A gantry bracket 28 is installed above the movable belt 26 to frame the hopper 3, improving the stability of the hopper 3 on the movable belt 26. The positioning mechanism 27 can be a position switch, located at the bottom of the movable belt 26, to position the hopper 3 along the conveying direction of the movable belt 26, facilitating the transport of the material tray 5 from the first conveyor track 41 into the hopper 3.
[0054] like Figure 7 The diagram shown is a structural schematic of the lifting platform in this embodiment. In this embodiment, a gantry support 28 is provided above the moving belt 26. A first side clamping mechanism 281 is installed on one side of the gantry support 28 for clamping the upper end of the hopper 3. A second side clamping mechanism 282 is installed on one side of the moving belt 26 for clamping the bottom of the hopper 3. The moving belt 26 includes two tracks, and a positioning plate 283 is provided between the two tracks.
[0055] In this embodiment, to facilitate the entry of the hopper 3 into the lifting platform 21, a relatively large width is required. Therefore, after the hopper 3 enters the lifting platform 21, it needs to be positioned laterally to facilitate the transport of the tray 5 to the corresponding layer of the hopper 3. Both the first side clamping mechanism 281 and the second side clamping mechanism 282 can include thrust cylinders. The thrust cylinder of the first side clamping mechanism 281 is installed on one side of the gantry bracket 28, and a corresponding baffle is installed on the other side. The second side clamping mechanism 282 can consist of two thrust cylinders, both installed on the guide rail of the moving belt 26, and pushing the bottom of the hopper 3 above the belt through the guide rail. In this embodiment, the use of the gantry bracket 28 not only improves the stability of the lifting platform 21 but also allows for simultaneous clamping of the upper and lower ends of the hopper 3, improving the positioning accuracy of the hopper 3. In this embodiment, an adjustable-width hopper 3 can be used. The stroke of the first side clamping mechanism 281 and the second side clamping mechanism 282 can be designed according to the width of the hopper 3 to ensure that the sides of the hopper 3 are clamped, improving the transport accuracy of the tray 5 entering the hopper 3.
[0056] The automatic unloading device provided in this embodiment can be installed in pairs side by side, such as Figure 8 The diagram shown is a structural schematic of the automatic unloading device with parallel dual tracks in this embodiment. The automatic unloading device with parallel dual tracks in this embodiment also includes a hopper support 8. The hopper support 8 is located on one side of the unloading frame 1 and includes upper and lower layers. Both upper and lower layers are equipped with belt conveyor mechanisms 81, which are used to connect with the hopper lifting device 2.
[0057] The hopper support 8 can store the hopper 3 and connects to the hopper lifting device 2 via a belt conveyor 81 to transfer the hopper 3 between the two. The upper hopper support 8 transfers the empty hopper 3 to the hopper lifting device 2. Once the hopper 3 is filled with the tray 5, it moves to the lower position with the lifting platform 21 of the hopper lifting device 2, and then is transferred to the lower hopper support 8 to complete the unloading. Operators can then retrieve the hopper 3 filled with the tray 5 from the lower hopper support 8. This embodiment further improves the automation level of the automatic unloading device and can save labor costs.
[0058] 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. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
