Description

Technical Field

[0001] This application relates to the field of material loading and unloading technology, and in particular to a material tray feeding device and its installation structure, and a material tray loading and unloading method. Background Technology

[0002] A material tray, also known as a material container, is a carrier used to hold processed parts. During processing or inspection, the material tray carries the products to be processed. Since the products are located at multiple workstations during processing or inspection, the material tray needs to be transported. The material tray transport mainly consists of three parts: tray separation and removal, transport, and empty tray collection. These steps usually require the coordination of multiple mechanisms located at different positions on the production line, resulting in a complex operating mechanism structure.

[0003] In order to improve feeding efficiency, existing material trays are usually stacked together when feeding. However, when the material trays are stacked together, it is difficult to keep feeding one tray at a time, resulting in poor feeding effect and affecting the overall process efficiency. Summary of the Invention

[0004] The present invention aims to solve at least one technical problem: existing tray feeding devices have difficulty maintaining a single tray feeding each time.

[0005] To address this, the present invention provides a material tray feeding device that separates the top tray from other trays by setting a tray disassembly mechanism, thereby achieving single-tray feeding for each feeding, improving the feeding effect and enhancing the overall process efficiency.

[0006] A tray feeding device according to an embodiment of the present invention includes:

[0007] A storage cabinet for storing multiple stacked trays, the top of which is open.

[0008] A tray-removing mechanism separates the top tray from other trays and transfers the top tray to an output position located at the top opening of the storage cabinet.

[0009] A conveying mechanism is provided on one side of the storage cabinet and opposite to the output position, and receives the material tray pushed from the output position and conveys the material tray to the target position.

[0010] A pushing device is used to push the tray located at the output position onto the conveying mechanism.

[0011] The beneficial effect of this invention is that by setting up a tray-splitting mechanism, the top tray is separated from other trays, thereby achieving single-tray feeding for each feeding, improving the feeding effect and enhancing the overall process efficiency.

[0014] A transmission assembly connected to the storage cabinet for simultaneously driving two connecting seats to move along the Z-axis;

[0015] A tray separation assembly is provided on each tray separation section, and the tray separation assembly is used to separate a tray located on the top layer at the output position from other trays.

[0016] According to one embodiment of the present invention, the disassembly assembly includes a disassembly component hinged to a connecting seat, the disassembly component having a bearing surface, the disassembly component having a first state and a second state, the disassembly component being in the first state with the bearing surface horizontally positioned, the disassembly component being able to rotate upward toward a direction away from the interior of the storage cabinet to the second state, and the disassembly component being able to return from the second state to the first state by a reset component.

[0017] According to one embodiment of the present invention, the bottom surface of the tray disassembly component protruding from the tray disassembly base is provided with a guide surface, and the end of the guide surface near the inside of the storage cabinet is inclined toward the bearing surface.

[0018] According to one embodiment of the present invention, each of the dismantling sections is connected to a plurality of dismantling components on the side wall facing the inside of the storage cabinet, and the plurality of dismantling components are arranged along the Z-axis direction.

[0019] According to one embodiment of the present invention, the top of the storage cabinet is provided with two support plates, which are respectively disposed on two opposite inner sidewalls of the storage cabinet. The support plates are hinged to the storage cabinet, and a reset member is also provided on the hinge axis between the support plates and the storage cabinet. The support plates are provided with a support surface, and the support plates have a first state and a second state. When the support plate is in the first state, the support surface is horizontally disposed. The support plate can rotate upward away from the interior of the storage cabinet to the second state. The support plate can be restored from the second state to the first state by the reset member.

[0020] According to one embodiment of the present invention, it further includes a lifting mechanism disposed within the storage cabinet for lifting a plurality of stacked trays and moving them toward the output position.

[0021] According to one embodiment of the present invention, an empty tray storage area is provided above the storage cabinet, the empty tray storage area is located above the output position, and a return device is provided on the conveying mechanism for pushing the empty tray below the empty tray storage area.

[0022] According to one embodiment of the present invention, the top of the storage cabinet is provided with four guide plates, the four guide plates are arrayed on the top of the storage cabinet, and an empty tray storage area is formed between the four guide plates. The side wall of the guide plate facing the empty tray storage area is also connected with a tray removal component for supporting the empty tray. The tray removal component on the guide plate is located above the support plate.

[0023] According to one embodiment of the present invention, the conveying mechanism includes mounting plates and a conveyor belt. Two mounting plates are provided, and the two mounting plates are connected to the rear side wall of the storage cabinet. The conveyor belt is disposed on the inner side of the two mounting plates via conveyor wheels and conveys the material tray along the Y-axis direction. The conveying mechanism is provided with a return device, which is used to push the material tray on the conveying mechanism back to the output position.

[0024] According to one embodiment of the present invention, a limiting plate is provided between the two mounting plates. The limiting plate is located near the storage cabinet and has an opening.

[0046] like Figure 1As shown, a material tray feeding device includes a storage cabinet 1, a lifting mechanism 2, a pushing device 3, a return device 4, a tray unloading mechanism 5, and a conveying mechanism 6.

[0047] The top of the storage cabinet 1 is set as an opening, and an output position 11 is set at the top opening of the storage cabinet 1. Multiple trays are stacked inside the storage cabinet 1. A lifting mechanism 2 is set on the storage cabinet 1 to lift the trays from the bottom of the multiple stacked trays toward the output position 11. A tray removal assembly 7 is set on the top of the storage cabinet 1. The tray removal assembly 7 separates one tray located on the top layer. A conveying mechanism 6 is connected to one side of the storage cabinet 1. One end of the conveying mechanism 6 is opposite to the output position 11. A pushing device 3 is set on the top of the storage cabinet 1. The pushing device 3 and the conveying mechanism 6 are respectively set on both sides of the output position 11. The pushing device 3 pushes the trays of the output position 11 toward the conveying mechanism 6, so that the trays enter the conveying mechanism 6.

[0048] An empty tray storage area 13 is provided above the storage cabinet 1. Multiple guide plates 12 are provided on the top of the storage cabinet 1. Four guide plates 12 are arrayed on the top of the storage cabinet 1, and the empty tray storage area 13 is formed between the four guide plates 12. The return device 4 is connected to the conveying mechanism 6 and is used to push the empty trays on the conveying mechanism 6 back to the top of the storage cabinet 1. The tray removal mechanism 5 is provided on the storage cabinet 1 and is used to separate a tray at the top of the output position 11 from other trays. As the lifting mechanism 2 lifts, the empty tray is lifted to the empty tray storage area 13 for storage.

[0049] Specifically, a cabinet door 14 is provided on the side of the storage cabinet 1 opposite to the conveying mechanism 6. The cabinet door 14 is located on the front side of the storage cabinet 1 (on the positive Y-axis side) and is used to convey material trays into the storage cabinet 1.

[0050] like Figure 2 , 3As shown, the lifting mechanism 2 includes a support plate 21, a first transmission assembly 22, and a first guide rail 229. The first transmission assembly 22 includes a drive source 221, a transmission shaft 222, a drive wheel 223, a transmission wheel 224, and a transmission belt 225. The drive source 221 is located inside the storage cabinet 1. The transmission shaft 222 is rotatably connected to the storage cabinet 1. The axial direction of the transmission shaft 222 is along the X-axis. Both ends of the transmission shaft 222 extend through the left and right side walls of the storage cabinet 1 (positive and negative X-axis directions). Drive wheels 223 are provided at both ends of the transmission shaft 222. 4. Two drive wheels 224 are respectively installed on the left and right (positive and negative X-axis directions) outer side walls of the storage cabinet 1. The drive wheels 224 are located directly above the opposing drive wheels 223 along the Z-axis. The drive wheels 224 and drive wheels 223 on the same side of the storage cabinet 1 are driven by a belt. Tensioning wheels 226 are also installed on the left and right side walls of the storage cabinet 1. The tensioning wheels 226 are located between the drive wheels 224 and drive wheels 223 and are located on one side of the belt, abutting against the belt. The installation position of the tensioning wheels 226 can be moved along the Y-axis. The drive source 221 is installed inside the storage cabinet 1. The output shaft of the drive source 221 is connected to a drive wheel, and the driven wheel 228 is coaxially connected to the drive shaft 222. The drive wheel and the driven wheel 228 are driven by a belt. In other embodiments, the drive wheel and the driven wheel 228 can be two meshing gears.

[0051] Multiple slides 227 are connected to the bottom of the support plate 21. In this embodiment, four slides 227 are arranged in a rectangular array at the bottom of the support plate 21. Two sliding openings 15 are respectively provided on the left and right side walls of the storage cabinet 1. The two sliding openings 15 on each side of the storage cabinet 1 are arranged along the Y-axis. The number of first guide rails 229 matches the number of slides 227. The four first guide rails 229 are respectively arranged on one side of the four sliding openings 15. The length direction of the first guide rails 229 and the sliding openings 15 are both arranged along the Z-axis. The ends of the four slides 227 away from the support plate 21 pass through the four sliding openings 15 respectively. The slides 227 are slidably connected to the first guide rails 229 through sliders. The two slides 227 located opposite each other on both sides of the storage cabinet 1 are respectively engaged with two belt drives. The drive source 221 drives the transmission shaft 222 to rotate via the drive wheel and driven wheel 228. The transmission shaft 222 drives the drive wheels 223 on both sides to rotate synchronously, thereby the belt drives the slide 227 to move along the Z-axis. The support plate 21, carrying multiple stacked material trays, moves towards the output position 11. Photoelectric sensors are also installed on the left and right side walls of the storage cabinet 1 to limit the stroke of the support plate 21.

[0052] The tray-removing mechanism 5 includes a second transmission assembly 51, a connecting seat 52, and a tray-removing assembly 7. Two connecting seats 52 are provided, symmetrically arranged on both sides of the storage cabinet 1. Each connecting seat 52 is slidably engaged with the storage cabinet 1 along the Z-axis via two second transmission assemblies 51. The structure of the second transmission assembly 51 is identical to that of the first transmission assembly 22, and will not be described further here. Each connecting seat 52 is engaged with a belt drive in one of the two second transmission assemblies 51. Second guide rails along the Z-axis are also provided on the left and right side walls of the storage cabinet 1, and the two ends of the connecting seats 52 are slidably engaged with the second guide rails via sliders.

[0053] The two ends of the connecting seat 52 are respectively connected to the mounting seats 53. In this embodiment, the connecting seat 52 is set as a U-shaped plate with the opening facing. The top of the storage cabinet 1 is provided with four notches 16. The ends of the four mounting seats 53 away from the connecting seat 52 are respectively located in the four notches 16. The part of the mounting seat 53 located in the notch 16 is defined as the disassembly section. There are multiple disassembly components 7 on the side wall of the disassembly section facing the inside of the storage cabinet 1. The multiple disassembly components 7 are arranged along the Z-axis direction. In this embodiment, two disassembly components 7 are provided on each disassembly section along the Z-axis direction.

[0054] like Figure 4 As shown, the tray removal assembly 7 includes a tray removal base 71 and a tray removal component 72. The tray removal base 71 is mounted on the mounting base 53 and has a mounting opening. The tray removal component 72 is hinged in the mounting opening. The tray removal assembly 7 also includes a reset component for controlling the reset of the tray removal component 72. In this embodiment, a torsion spring 73 is provided on the hinge shaft between the reset component 72 and the tray removal base 71. One end of the tray removal component 72 protrudes from the tray removal base 71 and is used to be inserted between adjacent trays. A guide surface 74 is provided on the bottom surface of the end of the tray removal component 72 that protrudes from the tray removal base 71. The tray removal components 72 located on the same side of the storage cabinet 1 can be connected together and integrally installed. When the torsion spring 73 is in its natural state, the top surface of the disassembly part 72 is set as the bearing surface, and the bearing surface is set horizontally. This is the first state of the disassembly part 72. The end of the guide surface 74 near the inside of the storage cabinet 1 is inclined towards the bearing surface. When the torsion spring 73 is in a deformed state, the disassembly part 72 flips upward. This is the second state. The disassembly part 72 is initially in the first state.

[0055] The top of the storage cabinet 1 is provided with two support plates 17, which are respectively set on the two opposite inner side walls of the storage cabinet 1. The length direction of the support plates 17 is set along the Y-axis. Both ends of the support plates 17 are hinged to the storage cabinet 1. A reset component, which is a torsion spring 73, is also provided on the hinge axis between the support plates 17 and the storage cabinet 1. The reset component is a torsion spring 73. A support surface is provided on the support plates 17. When the torsion spring 73 is in its natural state, the support plates 17 are set horizontally. This is the first state of the support plates 17. When the torsion spring 73 is in its deformed state, the support plates 17 are flipped upward. This is the second state of the support plates 17.

[0056] It should be noted that the bottom of the tray has four slots, which are located at the bottom of the two side walls along the long side of the tray. When the support plate 21, carrying multiple trays stacked on it, moves towards the output position 11 to the predetermined position, the lifting mechanism rises. The tray at the top level pushes the disassembly piece 72 upward along the guide surface 74 of the disassembly piece 72 on the lifting mechanism. The disassembly piece 72 rotates upward. When the tray at the top level moves above the disassembly piece 72, one end of the disassembly piece 72 protruding from the disassembly base 71 inserts between adjacent trays (into the slot on the tray) and resets under the action of the torsion spring 73, supporting the tray at the top level, thereby separating the tray at the top level from the other trays. The rising of the connecting seat 52 causes a material tray located at the top layer to rise until it moves above the support plate 17. The support plate 17 supports the material tray on the output position 11. The pushing device 3 pushes the material tray on the output position 11 towards the conveying mechanism 6. The pushing device 3 can be a rotary cylinder, linear cylinder, lead screw structure, etc., and there are no restrictions here. A photoelectric sensor can also be installed on the top of the storage cabinet 1 to detect whether there is a material tray at the output position 11, to prevent the pushing device 3 from running empty.

[0057] like Figure 5 As shown, the conveying mechanism 6 includes a mounting plate 61, a conveyor belt 62, and a motor 63. There are two mounting plates 61, which are connected to the rear side wall of the storage cabinet 1 and are located near the top of the storage cabinet 1. The conveyor belt 62 is located inside the two mounting plates 61 via a conveyor wheel, which is rotatably connected to the mounting plate 61. The motor 63 drives the conveyor wheel to rotate, and the conveyor belt 62 conveys the material tray along the Y-axis.

[0058] A limiting plate 43 is provided between the two mounting plates 61. The limiting plate 43 is located near the storage cabinet 1 and has a through-hole 44 that penetrates the side wall of the limiting plate 43 near the storage cabinet 1. The return device 4 includes a pusher 41 and a pusher plate 42. The pusher 41 controls the movement of the pusher plate 42 along the Y-axis. In this embodiment, the pusher 41 moves linearly along the Y-axis through a screw-slider mechanism. A slide rail can also be provided between the mounting plates 61 to guide the pusher 41. A photoelectric sensor is provided on the slide rail to limit the movement stroke of the pusher 41.

[0059] One end of the push plate 42 is hinged to the output end of the push member 41. An elastic element is provided at the hinge between the push plate 42 and the push member 41. In this embodiment, the elastic element is also a torsion spring 73. The push plate 42 is provided with an abutment surface. Under the action of the torsion spring 73, the abutment surface is always in contact with the bottom of the limiting plate 43. The push member 41 is located on the side of the opening 44 away from the storage cabinet 1. In the initial state, the push plate 42 is located below the limiting plate 43. The push member 41 controls the push plate 42 to face the opening. As the opening 44 moves to one side, the push plate 42 emerges from the bottom of the limiting plate 43 and rotates to the top of the conveyor belt 62 and the limiting plate 43, thereby pushing the empty tray toward the storage cabinet 1. The contact surface is set as an inclined surface facing away from the storage cabinet 1. When the push plate 42 moves away from the storage cabinet 1, the contact surface contacts the lower edge of the side wall of the opening 44 away from the storage cabinet 1 and rotates, returning to its initial position.

[0060] When the next empty tray moves above the storage cabinet 1, it is located at the bottom of the previous empty tray. The previous empty tray, pushed by the next empty tray, moves upward along the guide surface 74 on the tray removal component 72 at the output position 11, thus allowing the empty tray to enter the empty tray storage area 13 from the bottom. A tray removal component 7 is also connected to the side wall of the guide plate 12 facing the empty tray storage area 13 to support the empty trays. The tray removal component 7 on the guide plate 12 is located above the support plate 17. Preferably, the distance between the tray removal component 7 and the support plate 17 is greater than the height of one tray but less than the height of two trays.

[0061] Furthermore, protective plates 18 are provided on both the left and right side walls of the storage cabinet 1. The protective plates 18 cover the side walls of the storage cabinet 1 to protect the first transmission component 22, the second transmission component 51, the connecting seat 52 and other components.

[0062] It should be noted that, as Figure 6 As shown, when the material tray feeding device is assembled with the working mechanism, the storage cabinet 1 is installed on the outside of the working mechanism, and the conveying mechanism 6 can extend into the working mechanism and be installed inside the working mechanism. The material tray feeding device works with the working mechanism to send the material tray into the working mechanism, which can shorten the movement path of the machine head in the working mechanism, thereby reducing the overall space occupied by the working mechanism.

[0063] A method for loading and unloading materials onto a tray, comprising:

[0064] Step 1, full tray loading: Open the upper cabinet door 14 and place multiple trays with heat dissipation covers onto the support plate 21 (maximum 10 trays). After successful loading, the support plate 21 will reflect a photoelectric signal.

[0065] Step 2, First tray dismantling: Lifting mechanism 2 controls multiple trays to rise and transport them toward dismantling mechanism 5 until the top tray abuts against dismantling component 72 in dismantling mechanism 5. Dismantling component 72 rotates and changes from the first state to the second state. After the top tray moves above dismantling component 72, dismantling component 72 resets under the action of torsion spring 73, returning to the first state and inserting into the slot on the tray, thereby separating one top tray from the other trays. Connecting seat 52 rises and moves the top tray to abut against support plate 17. Support plate 17 rotates and changes from its first state to the second state. After the top tray moves above support plate 17, support plate 17 resets to the first state under the action of torsion spring 73. Support plate 17 supports the bottom of the tray, thereby moving the tray to output position 11. Connecting seat 52 descends.

[0066] Step 3, feeding: The pushing device 3 pushes the material tray on the output position 11 toward the conveying mechanism 6, and the material tray moves onto the conveyor belt 62 and moves toward the working equipment through the conveyor belt 62. The material tray moves to the target position and waits to be picked up.

[0067] Step 4, Empty Disk Recycling: After the working mechanism completes the material picking, it receives a signal from the working mechanism, and the conveyor belt 62 reverses its rotation to transport the empty disk toward the output position 11. When the empty disk moves above the opening 44 and the push plate 42 is close to the output position 11, the pusher 41 moves, and the push plate 42 protrudes from the opening 44 to push the empty disk to the output position 11.

[0068] Step 5, Subsequent Disassembly: After the first tray is disassembled, the connecting seat 52 descends and resets. In this step, the connecting seat 52 rises again to disassemble the next tray located on the top layer. The disassembled tray is supported on the disassembly component 72 located below the connecting seat 52. The connecting seat 52 continues to rise, and the disassembly component 72 located above the connecting seat 52 supports the empty tray that has returned to the output position 11 and pushes it to the empty tray storage area 13. The empty tray is supported on the disassembly component 72 in the empty tray storage area 13. At the same time, the disassembled tray is moved to the support plate 17 to wait for discharge.

[0069] Step six: Repeat steps three to five until all material trays have been filled. During this process, when the empty tray storage area 13 is full of empty trays, the empty trays must be removed in time.
