Abstract
Description
Technical Field
[0001] This invention relates to the field of auxiliary equipment for toolbox production, and in particular to an auxiliary device for a toolbox production line. Background Technology
[0002] A toolbox, as the name suggests, is a container used to store tools and various household items. It can be used for various purposes such as production, home, repair, and fishing, and is widely used. Currently, toolboxes on the market are generally made of engineering plastic injection molding or compression molding, which has good load-bearing capacity, beautiful and elegant appearance, strong plasticity, and a variety of colors.
[0003] In the toolbox production process, after each component is manufactured on its respective machine tool, a robotic arm picks it up and places it on a conveyor belt. The conveyor belt is generally a conveyor belt, with multiple workstations set up on the outer side of the conveyor belt away from the machine tool. After the toolbox components placed on the conveyor belt are transported to the designated position, the workers at the workstations pick up some of the toolbox components from the conveyor belt for assembly. This eliminates the need for personnel to manually pick up each component from the machine tool, improving overall work efficiency. However, the toolbox components are scattered on the conveyor belt, which may result in personnel missing or taking too many, or encountering defective products. When personnel leave the workbench to pick up or put back the missing components, it will affect the assembly efficiency of themselves or subsequent personnel. At the same time, there are individual differences between personnel, and when the conveyor belt is too wide, it is inconvenient for personnel to reach into it to pick up the components, which affects assembly efficiency. There are also safety hazards for personnel when they are close to the conveyor belt during transportation. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an auxiliary device for toolbox production lines.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an auxiliary device for a toolbox production line, comprising a conveyor belt for conveying toolbox components and a workbench disposed on its side wall for assembly by personnel. Several sets of workbench are arranged sequentially along the length of the conveyor belt. A second conveyor belt is disposed between the first conveyor belt and the workbench along the length of the first conveyor belt. An extension plate is disposed on the second conveyor belt, and a storage box is rotatably connected to the extension plate via a connecting rod. Several sets of storage boxes are disposed along the length of the first conveyor belt, with each set of storage boxes facing each set of workbench. Supports for the storage boxes are disposed at the left and right ends of the upper side of the first conveyor belt, and one side of each storage box is open. The support has a through hole, and a guide plate rotatably mounted on the support opposite to the through hole. A rack is mounted on the side of the storage box away from the through hole along its length. A gear meshing with the rack is mounted on the support. A motor is mounted on one of the conveyor belts, and the output shaft of the motor is connected to the gear via a rotating rod. A lifting component is mounted on the support facing the guide plate. The lifting component includes a drive wheel rotatably mounted on the support, a lifting rod located below the guide plate, and a driven wheel sleeved on the outer wall of the lifting rod. The drive wheel meshes with the driven wheel, and a transmission rod is mounted on the drive wheel. The transmission rod is connected to the output shaft of the motor for belt drive. The outer wall of the lifting rod is provided with an external thread, and the inner wall of the driven wheel is provided with an internal thread that is screwed into the external thread.
[0006] Preferably, an electromagnetic attraction block and a magnetic attraction block are provided on opposite sides of the transmission rod and the drive wheel.
[0007] Preferably, the rotating rod and the output shaft of the motor are respectively provided with a magnetically attracted block II and an electromagnetically attracted block II on opposite sides.
[0008] Preferably, the upper side of the lifting rod has an arc surface.
[0009] Preferably, the storage box has an opening at the bottom inside, and a baffle is rotatably installed at the opening. The side of the storage box away from the workbench is inclined.
[0010] Preferably, the guide plate is provided with a guide plate.
[0011] Preferably, the placement box is provided with a cover plate that can be rotated by a rotating rod, the cover plate is provided with an observation window, and the upper side of the cover plate away from the rotating rod is provided with a handle.
[0012] Preferably, a torsion spring is fitted on the outer wall of the rotating rod, with one end of the torsion spring connected to the placement box and the other end connected to one side of the cover plate.
[0013] Preferably, a cylinder is provided on the side of the workbench facing the second conveyor belt, a limit plate is provided at the top of the piston rod of the cylinder, a pressure sensor is provided on the outer wall of the placement box, and a ball bearing is provided on the side of the limit plate facing the pressure sensor.
[0014] Preferably, the workbench is equipped with indicator lights.
[0015] The beneficial effects of this invention, compared with the prior art, are as follows: This invention sets up a second conveyor belt between the first conveyor belt and the worktable. A storage box is installed on the second conveyor belt for personnel at the worktable to place and retrieve excess toolbox parts, eliminating the need for personnel to leave the worktable to return or retrieve them, thus reducing the impact on work efficiency during assembly. Simultaneously, a storage box slides on the first conveyor belt, with a rotating guide plate on it. This eliminates the need for personnel to sort and retrieve toolbox parts from the first conveyor belt; the parts are guided into the storage box by the guide plate. The storage box moves to the worktable, and the toolbox parts fall onto the worktable through a through-hole in the opening of the baffle. This avoids the safety hazards of personnel reaching into the first conveyor belt to retrieve parts, and also reduces the time-consuming and laborious problem of manual retrieval, thereby improving the overall assembly efficiency of the toolbox.

All technical solutions that fall within the scope of the present invention should be considered within the scope of protection of the present invention. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
[0024] It should be noted that in this document, relational terms such as first and second, or "connecting plate one, connecting plate two," are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0025] The directional terms mentioned in this embodiment, such as "up," "down," "left," and "right," are merely used to help those skilled in the art understand the relationships between various features or parts in conjunction with the accompanying drawings.
[0026] In this embodiment, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0027] like Figures 1 to 6As shown, an auxiliary device for a toolbox production line includes a conveyor belt 1 for transporting toolbox components. Multiple workbenches 35 are arranged along the length of conveyor belt 1 on the right rear end. These workbenches 35 are used by personnel to place and assemble toolboxes. A second conveyor belt 2 is arranged between conveyor belt 1 and the workbenches 35 along the length of conveyor belt 1. It should be noted that the drive mechanisms of both conveyor belts 1 and 2 operate independently. In this embodiment, the drive mechanisms employ motors, a technique commonly used by those skilled in the art. Rectangular extension plates 33 are vertically fixed at opposite ends on the outer wall of conveyor belt 2. A placement box 34 is arranged between the two sets of extension plates 33. A connecting rod 32 is provided on the side of the extension plate 33 facing the placement box 34, rotatably connecting it to the placement box 34. In this embodiment, the height of the placement box 34 is lower than that of the extension plate 33. This is to ensure that when the conveyor belt 2 circulates and drives the placement box 34, the outer wall of the placement box 34 will not come into contact with or interfere with the outer wall of the conveyor belt 2. A cover plate 29 is provided at the upper end of the placement box 34 to prevent the toolbox parts inside the placement box 34 from falling out. The rear end of the cover plate 29 is rotatably connected to the placement box 34 via a rotating rod 19. A torsion spring 11 is sleeved on the outer wall of the rotating rod 19. The opposite ends of the torsion spring 11 are fixedly connected to the opposite sides of the placement box 34 and the cover plate 29, so that the cover plate 29 can be reset in time after being opened. An embedded handle 30 is fixed on the upper front end of the cover plate 29 to facilitate personnel to open the cover plate 29. A transparent observation window 31 is embedded on the upper side of the cover plate 29 to facilitate personnel to observe the situation inside the placement box 34 in time.
[0028] A cylinder 6 is fixed on the side of the workbench 35 facing the second conveyor belt 2. The cylinder 6 is located directly above the second conveyor belt 2 and above the placement box 34. The top of the piston rod of the cylinder 6 faces the placement box 34, and a cuboid limiting plate 7 is fixed to the piston rod of the cylinder 6. The limiting plate 7 is located directly above the first conveyor belt 1. A pressure sensor 9 is fixed on the side of the placement box 34 facing the rear end of the first conveyor belt 1. The pressure sensor 9 adopts a technical component commonly used by those skilled in the art. Its purpose is that after contacting the limiting plate 7 and being pressed to a certain extent, the movement of the second conveyor belt 2 can be stopped by the control system, which plays a safety limiting role and avoids the placement box 34 not stopping immediately after contacting the limiting plate 7. Furthermore, movable ball bearings 8 are embedded along the length of the limiting plate 7 on the side facing the pressure sensor 9. The purpose is to reduce the friction between the limiting plate 7 and the pressure sensor 9 and reduce the wear on the surface of the pressure sensor 9 when the limiting plate 7 no longer limits the placement box 34 and needs to move upward.
[0029] An indicator light is fixed on the side of the workbench 35 facing the conveyor belt 2, directly above the cylinder 6. The indicator light is electrically connected to the cylinder 6. Its purpose is to change the indicator light to different colors when the cylinder 6 moves. This can be achieved by a PLC controller, so that the personnel on the workbench 35 can understand the assembly status required by the personnel in front.
[0030] A rectangular storage box 13 is positioned directly above the conveyor belt 1 and opposite each set of worktables 35. T-shaped brackets 16 are fixed on the left and right side walls of the conveyor belt 1. The length of the storage box 13 is longer than the width of the conveyor belt 1. An inner cavity (not shown in the attached drawing) is opened at the end of the storage box 13 directly above the conveyor belt 1. An inclined surface is provided on the side of the inner wall of the inner cavity away from the worktable 35. The inclined surface is designed to move downward toward the worktable 35 assembly. A rectangular opening (not shown in the attached drawing) is opened at the bottom of the inner cavity. Rectangular baffles 15 are positioned opposite each other at the opening. The length of the two sets of baffles 15 is greater than the minimum distance between the two sets of opposing brackets 16. The purpose is to avoid the lower end being unsupported when the baffles 15 are directly above the conveyor belt 1.
[0031] like Figure 4 As shown, the front and rear ends of the baffle 15 are rotatably connected to the front and rear sides of the inner wall of the opening. This is so that when opened, the middle section opens first, allowing the toolbox components inside the storage box 13 to fall out first, preventing them from falling out from the edges. The two sets of baffles 15 also provide some guidance when they rotate open. It should be noted that the length of the storage box 13 is such that when one end of the inner cavity of the storage box 13 is directly above the workbench 35, the other end is still on a set of supports 16 near the conveyor belt 2. The supports 16 can always provide support for the storage box 13. For support, a rack 12 is fixed along the length of the storage box 13 on the side away from the front end of the conveyor belt 1. A rectangular through hole 14 is opened on the other side of the storage box 13. A guide plate 3 is set at the through hole 14. The guide plate 3 is rotatably connected to the inner wall of the two sets of brackets 16. A fan-shaped guide plate 4 is fixed on the upper side of the guide plate 3 away from the second conveyor belt 2. The purpose is to guide and collect the toolbox parts on the first conveyor belt 1 into the storage box 13 through the guide plate 3. The guide plate 4 is used to guide the moving toolbox parts to a suitable position on the guide plate 3.
[0032] A motor 23 is fixed to the lower end of the bracket 16, with the output shaft of the motor 23 facing upwards. Figure 5As shown, a rotating rod 19 is vertically mounted on the top of the output shaft and rotatably connected to it. An electromagnetic suction block 17 is embedded on the top of the output shaft of the motor 23. A magnetically attracted block 20, which magnetically engages with the electromagnetic suction block 17, is embedded at the lower end of the rotating rod 19. A gear 18, which meshes with the rack 12, is fixedly fitted onto the outer wall of the upper end of the rotating rod 19. A transmission rod 36 is rotatably mounted on the lower side of the bracket 16 facing the front end of the conveyor belt 1. The transmission rod 36 is connected to the output shaft of the motor 23 via belt drive. A drive wheel 28 is mounted on the lower side of the transmission rod 36 and rotatably mounted on the bracket 16. On the upper part, electromagnetic attraction block 22 and magnetic attraction block 21 with magnetic attraction are respectively provided on the opposite side between the transmission rod 36 and the drive wheel 28. A driven wheel 27 that meshes with the drive wheel 28 is rotatably provided on the bracket 16. The driven wheel 27 is located directly below the guide plate 3. A lifting rod 26 is vertically provided in the middle of the driven wheel 27. The inner wall of the driven wheel 27 is provided with an internal thread 24. The outer wall of the lifting rod 26 is provided with an external thread 25 that is screwed into the internal thread 24. The upper end face of the lifting rod 26 is designed with an arc, the purpose of which is to make the rotation of the guide plate 3 smoother when it is pushed up.
[0033] It should be noted that in this embodiment, the conveyor belt is used to move and place the box 34. The purpose is to optimize the movement logic. The horizontal reciprocating movement may cause problems, such as when the personnel on the first workbench 35 have extra toolbox parts to place, and the personnel on the second workbench 35 happen to need them. The box 34 is at the rear of the second workbench 35. With the horizontal reciprocating movement, it will pass through the second workbench 35 first, so that the box 34 is blocked by the limiting plate 7 on the second workbench 35 before the personnel on the first workbench 35 can place the toolbox parts on it.
[0034] When the personnel on the workbench 35 are assembling the toolbox components on the workbench 35 without needing to retrieve new components from the conveyor belt 1, the end of the storage box 13 with an inner cavity is located directly above the conveyor belt 1. The guide plate 3 is located at the front end of the through hole 14 of the storage cavity to block it. The lower end of the lifting rod 26 is located in the driven wheel 27. The two sets of baffles 15 are supported by the bracket 16. The motor 23 is in a de-energized state. At the same time, the electromagnetic suction block 12 and the electromagnetic suction block 27 are both in an energized state. The purpose is to limit the position of the rotating rod 19 and the transmission rod 36. At this time, the toolbox components moving on the conveyor belt 1 will pass under the storage box 13.
[0035] When personnel need to assemble new toolbox components on conveyor belt 1, they first de-energize the electromagnetic chuck 17 via the control system, preventing the rotating rod 19 from being driven by the output shaft of motor 23. Then, motor 23 starts rotating forward. Motor 23 is connected to transmission rod 36 via belt drive, driving wheel 28 to rotate. Driven wheel 28 drives driven wheel 27 to rotate. Driven wheel 27 is limited to rotating around its own central axis on bracket 16. The internal thread 24 of driven wheel 27 engages with the external thread 25 of lifting rod 26, driving lifting rod 26 to rotate. As the guide plate 3 moves vertically downwards, it begins to rotate around its central axis at the connection point with the bracket 16 due to gravity. Its upper end gradually approaches and contacts the upper surface of the conveyor belt 1. The conveyor belt 1 continues to move, and the toolbox components on the conveyor belt 1 gradually move onto the guide plate 3. After placement, the operator reverses the motor 23, thereby indirectly driving the lifting rod 26 to move vertically upwards. The guide plate 3 is simultaneously pushed upwards, and the toolbox components on it, due to gravity and the surface slope of the guide plate 3, enter the storage box 13 through the through hole 14. Then, the operator stops energizing electromagnetic block 22, allowing electromagnetic block 17 to re-energize. Motor 23 begins to rotate forward. At this time, because electromagnetic block 22 is no longer magnetically attracted by electromagnetic block 21, drive wheel 28 cannot be synchronously driven by transmission rod 36. Rotating rod 19 begins to rotate, and gear 18 on rotating rod 19 begins to mesh with rack 12, causing rack 12 to move horizontally. Storage box 13, fixed to rack 12, begins to move horizontally on support 16 towards the operator's workbench 35. The process stops when the baffle 15 under the storage box 13 moves out of the support range of the bracket 16. Without support, the baffle 15 begins to rotate downwards, and the toolbox parts on the baffle 15 fall onto the workbench 35. After falling, the personnel close the baffle 15 and then start the motor 23 to reverse, indirectly driving the inner cavity of the storage box 13 to reset and move directly above the conveyor belt 1. The baffle 15 is then supported by the bracket 16 again, completing the retrieval operation of the toolbox parts from the conveyor belt 1 to the personnel's workbench 35, reducing the safety hazards of personnel handling the parts.
[0036] It should be noted that some defective parts are produced during the manufacturing of the toolbox. When a person takes it, a set of toolboxes will be missing parts. The person can directly place the toolbox parts other than the defective ones into the placement box 34. If other defective parts need to be replaced later, the person can take the toolbox parts from the placement box 34.
[0037] When a person needs to place toolbox parts into the placement box 34, the control system activates the cylinder 6, the second conveyor belt 2, and the indicator light. The cylinder 6 pushes the limit plate 7 down to align with the pressure sensor 9 on the upper side of the placement box 34 on the second conveyor belt 2. The second conveyor belt 2 then moves the placement box 34. When it reaches the position of the workbench 35 where the toolbox parts need to be placed, the pressure sensor 9 contacts the limit plate 7. After the pressure sensor 9 receives a certain pressure, the control system stops the second conveyor belt 2. Then, the person pulls the cover plate 29 to put the toolbox parts in. After the parts are placed in, the cylinder 6 moves the limit plate 7 up, no longer obstructing the placement box, so that the person who needs to find the toolbox parts later can move the placement box 34 over.
[0038] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
