Description

Technical Field

[0001] This application relates to the field of component transfer, and in particular to a component processing and transfer device. Background Technology

[0002] When processing or assembling parts, parts usually do not have only one process. Transfer devices are needed for the transition between processes. Transfer devices can transfer parts in batches from one process to another, improving the efficiency of parts movement.

[0003] In order to increase the number of parts that can be transferred at one time, current transfer devices stack multiple layers in the height direction, thereby increasing the number of parts that can be transferred without changing the footprint of the transfer device itself.

[0004] The larger the component, the greater the gap between adjacent placement layers, and the higher the transfer device needs to be. Some transfer devices even require workers to climb ladders to place large components on higher placement layers. This not only increases the time spent retrieving and placing components but also increases the risk of accidents for workers handling the components. Summary of the Invention

[0005] In order to improve the efficiency of picking up and placing large parts on the transfer device and to improve the safety factor of workers when handling parts on the transfer device, this application provides a parts processing transfer device.

[0006] The component processing and transfer device provided in this application adopts the following technical solution:

[0007] A parts processing and transfer device includes a support frame, a first belt, a second belt, a placement rack, and a drive assembly;

[0008] The first belt and the second belt have the same structure and are both mounted on the support frame. The first belt and the second belt are arranged horizontally opposite each other and rotate and transmit on the same vertical plane.

[0009] The placement racks are connected to the first belt and the second belt respectively, and there are multiple placement racks, which are arranged at intervals along the vertical direction;

[0010] The drive assembly is mounted on the support frame and connected to the first belt and the second belt. The drive assembly is used to drive the placement rack to rise and fall by synchronously driving the first belt and the second belt in opposite directions.

[0011] By adopting the above technical solution, when workers place parts on the transfer device, the drive assembly first drives the first and second belts to move forward, causing the highest placement rack to move downwards, making it easier for workers to place parts on it. Then, as the drive assembly drives the first and second belts to move in the opposite direction, workers place parts sequentially in batches on the placement racks, thus completing the placement process. When retrieving parts, as the drive assembly drives the first and second belts to rotate forward, the highest placement rack gradually moves downwards to a suitable position for workers to retrieve them. This minimizes the need for workers to climb ladders to access parts at higher positions, improving the efficiency of handling large parts on the transfer device and increasing the safety of workers when moving parts on it.

[0012] Optionally, the placement rack includes a first placement plate and a second placement plate with the same structure and arranged horizontally opposite each other. The first placement plate is mounted on a first belt, and the second placement plate is mounted on a second belt. Both the first placement plate and the second placement plate are provided with limiting components for restricting the position of the parts.

[0013] By adopting the above technical solution, the first and second placement plates on the same placement rack are raised and lowered synchronously, and the parts on the placement rack will shake when the moving transfer device is used. The parts can be limited by the limiting component, thereby reducing the probability of the parts falling.

[0014] Optionally, the limiting assembly includes a clamping plate, a control component, and a release component;

[0015] The clamping plate is slidably connected to the upper surface of the first placement plate in a direction close to or away from the second placement plate. The control component is connected to the clamping plate and is used to control the sliding direction of the clamping plate. The release component is installed on the support frame and is flush with the lowermost first placement plate.

[0016] When the control member contacts the release member, the control member controls the clamping plate to slide in a direction away from the second placement plate. When the control member moves away from the release member, the control member controls the clamping plate to slide in a direction closer to the second placement plate.

[0017] By adopting the above technical solution, when the placement rack is raised and lowered vertically, the placement rack at the bottom will also change. When one of the placement racks moves to the bottom, the release mechanism can drive the clamping plate to slide along the direction close to the second placement plate through the control mechanism, so that the operator can place the parts between the clamping plates on the first and second placement plates. As the placement rack rises or falls, the control mechanism moves away from the release mechanism, and the clamping plates on the first and second placement plates abut against the parts, thereby limiting the position of the parts.

[0018] Optionally, the control component includes a reset spring, a first slide rod, a second slide rod, and a control spring;

[0019] The reset spring is arranged along the sliding direction of the clamping plate and its two ends are respectively connected to the clamping plate and the first placement plate. The first slide rod is slidably connected to the first placement plate along the sliding direction parallel to the clamping plate. The control spring is arranged along the sliding direction of the clamping plate and its two ends are respectively connected to the first slide rod and the first placement plate. The release member is located on the side of the first slide rod away from the control spring. The second slide rod is slidably connected to the first placement plate along the direction perpendicular to the clamping plate and its two ends abut against the first slide rod and the clamping plate, respectively.

[0020] When the first slide bar abuts against the release member, the first slide bar pushes the second slide bar to slide in a direction close to the clamping plate, causing the clamping plate to slide in a direction away from the second placement plate.

[0021] By adopting the above technical solution, when the control component comes into contact with the release component, the first slide rod slides along the direction close to the second placement plate, causing the control spring to contract. The first slide rod pushes the second slide rod to slide along the direction close to the clamping plate, causing the clamping plate to move away from the second placement plate. The reset spring extends, so as to facilitate the handling of parts.

[0022] Optionally, the release component includes a mounting rod and a release block. The mounting rod is mounted on the support frame and located on the side of the first placement plate opposite to the second placement plate. The release block is mounted on the mounting rod. The upper end surface of the release block is a first inclined surface that slides against the first sliding rod, and the lower end surface is a second inclined surface that slides against the first sliding rod. The first inclined surface slopes downward in the direction close to the first placement plate, and the first and second inclined surfaces are symmetrically arranged.

[0023] By adopting the above technical solution, when the first sliding rod abuts against the release block from top to bottom, it slides against the first sliding rod via the first inclined surface. When the first sliding rod abuts against the release block from bottom to top, it slides against the first sliding rod via the second inclined surface. This achieves the effect of pushing the first sliding rod to slide in a direction closer to the second placement plate.

[0024] Optionally, one end of the second slide bar is a third inclined surface that slides against the first slide bar, and the other end is provided with a fourth inclined surface that slides with the clamping plate. The third inclined surface is arranged at an angle away from the first slide bar and away from the second placement plate. The fourth inclined surface and the third inclined surface are arranged symmetrically.

[0025] By adopting the above technical solution, when the first slide rod slides in the direction close to the second placement plate, the first slide rod and the third inclined surface slide against each other, thereby driving the second slide rod to slide in the direction close to the clamping plate. The clamping plate and the fourth inclined surface slide against each other, thereby driving the clamping plate to slide in the direction away from the second placement plate.

[0026] Optionally, a lower pressure plate is provided on the upper surface of the clamping plate, and the lower pressure plate is located on the side of the clamping plate directly opposite the second placement plate.

[0027] By adopting the above technical solution, when the clamping plate abuts against the component, the lower end face of the pressure plate abuts against the component, thereby limiting the position of the component in the vertical direction through the first placement plate, the second placement plate and the pressure plate, further strengthening the limiting strength of the component.

[0028] Optionally, a first baffle is provided on the upper surface of the first placement plate along one side perpendicular to the sliding direction of the clamping plate, and a second baffle is provided on the side of the clamping plate opposite to the first baffle.

[0029] By adopting the above technical solution, the horizontal position of the component is further limited by the first baffle and the second baffle, thereby further strengthening the horizontal limiting strength of the component.

[0030] Optionally, the drive assembly includes a drive motor, a first rotary rod, a second rotary rod, and a steering component;

[0031] The drive motor is mounted on the support frame. One end of the first rotating rod is coaxially fixed to the pulley of the first belt and the other end is coaxially connected to the output shaft of the drive motor. One end of the second rotating rod is coaxially fixed to the pulley of the second belt and the other end is connected to the output shaft of the drive motor through a steering component. The steering component is used to control the second belt to drive in the opposite direction to the first belt.

[0032] By adopting the above technical solution, in order for the first and second placement plates to rise and fall synchronously, the first and second belts must rotate in opposite directions. Through the connection of the first rotating rod, the steering component, and the drive motor, the first rotating rod and the drive motor rotate in the same direction, while the second rotating rod and the drive motor rotate in opposite directions, thereby achieving the effect of the first and second belts rotating in opposite directions.

[0033] Optionally, the steering component includes a first bevel gear, a second bevel gear, and a third rotating rod;

[0034] The first bevel gear is coaxially mounted on the first rotating rod, the second bevel gear is coaxially mounted on the second rotating rod, and the third rotating rod is rotatably mounted on the support frame and located between the first belt and the second belt. One end of the third rotating rod is coaxially connected to a third bevel gear that meshes with the first bevel gear, and the other end of the third rotating rod is coaxially connected to a fourth bevel gear that meshes with the second bevel gear.

[0035] By adopting the above technical solution, the direction of the drive motor can be changed through the first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear, so that the first belt and the second belt rotate in opposite directions and can rotate synchronously, thereby improving the synchronization of the first belt and the second belt.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. When staff members are handling parts, the higher placement racks can be moved down to a height that is easy for staff to reach, thereby minimizing the need for staff to climb ladders to retrieve parts from high places, improving the efficiency of handling large parts on the transfer device and the safety of staff when moving parts on the transfer device.

[0038] 2. When the placement rack moves to the detached part, the control unit drives the clamping plate to slide along the direction close to the second placement plate, so that the operator can place the part between the clamping plates on the first and second placement plates to limit the part.

[0039] 3. When the control component comes into contact with the release component, the first slide rod slides in the direction close to the second placement plate, and the first slide rod pushes the second slide rod to slide in the direction close to the clamping plate, so that the clamping plate moves in the direction away from the second placement plate, so as to facilitate the picking and placing of parts.

[0046] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0047] This application discloses a parts processing and transfer device. (Refer to...) Figure 1 and Figure 2 The transfer device includes a support frame 1, a first belt 2, a second belt 3, a placement rack 4, a drive assembly 5, and a limiting assembly 6.

[0048] The first belt 2 and the second belt 3 are mounted on the upper surface of the support frame 1, and casters are installed below the support frame 1 to facilitate the movement of the transfer device. The first belt 2 and the second belt 3 have the same structure and are arranged horizontally at intervals. The first belt 2 and the second belt 3 rotate and transmit on the same vertical plane, making them suitable for lifting applications. The placement rack 4 includes a first placement plate 41 and a second placement plate 42 with the same structure and arranged horizontally at intervals. The first placement plate 41 is mounted on the first belt 2, and the second placement plate 42 is mounted on the second belt 3, allowing parts to be placed on the first placement plate 41 and the second placement plate 42 for support. Multiple placement racks 4 are arranged at intervals along the vertical direction to support more parts. Limiting components 6 are installed on both the first placement plate 41 and the second placement plate 42 to limit the movement of parts.

[0049] Furthermore, since the placement frame 4 is located between the first belt 2 and the second belt 3, in order for the first belt 2 and the second belt 3 to drive the placement frame 4 to rise and fall, the drive assembly 5 is connected to the first belt 2 and the second belt 3, and the drive assembly 5 drives the first belt 2 and the second belt 3 to move synchronously in opposite directions. When the placement frame 4 rises, the first belt 2 rotates forward and the second belt 3 rotates in the opposite direction, and the first belt 2 and the second belt 3 move in opposite directions. When the placement frame 4 falls, the first belt 2 rotates in the opposite direction and the second belt 3 rotates forward, and the first belt 2 and the second belt 3 move in the forward direction.

[0050] When staff members are handling parts, the higher placement rack 4 can be moved down to a height that is easy for staff to reach, thereby minimizing the need for staff to climb ladders to retrieve parts from high places, improving the efficiency of handling large parts on the transfer device and the safety of staff when moving parts on the transfer device.

[0051] Reference Figure 2 The drive assembly 5 includes a drive motor 51, a first rotating rod 52, a second rotating rod 53, and a steering component 54.

[0052] The drive motor 51 is mounted on the support frame 1. One end of the first rotating rod 52 is coaxially fixed to the pulley of the first belt 2, and the other end is coaxially connected to the output shaft of the drive motor 51. One end of the second rotating rod 53 is coaxially fixed to the pulley of the second belt 3, and the other end is connected to the output shaft of the drive motor 51 through the steering component 54.

[0053] The steering component 54 includes a first bevel gear 541, a second bevel gear 542, and a third rotating rod 543. The first bevel gear 541 is coaxially mounted on the first rotating rod 52, the second bevel gear 542 is coaxially mounted on the second rotating rod 53, and the third rotating rod 543 is rotatably mounted on the support frame 1 and located between the first belt 2 and the second belt 3. One end of the third rotating rod 543 is coaxially connected to a third bevel gear 544 that meshes with the first bevel gear 541, and the other end of the third rotating rod 543 is coaxially connected to a fourth bevel gear 545 that meshes with the second bevel gear 542. When the drive motor 51 drives the first rotating rod 52 to rotate forward, the steering component 54 can drive the second rotating rod 53 to rotate in the opposite direction, thereby achieving synchronous and unidirectional transmission of the first belt 2 and the second belt 3.

[0054] Since the first placement plate 41 and the second placement plate 42 have the same structure, this embodiment uses the limiting component 6 on the first placement plate 41 as an example. The position of the limiting component 6 on the first placement plate 41 is the same as the position on the second placement plate 42. (Refer to...) Figure 2 and Figure 3 The limiting assembly 6 includes a clamping plate 61, a control member 62, a release member 63, a lower pressure plate 64, a first baffle 65, and a second baffle 66. The clamping plate 61 is slidably connected to the upper surface of the first placement plate 41 in a direction close to or away from the second placement plate 42. The control member 62 is connected to the clamping plate 61, and the release member 63 is mounted on the support frame 1 and is flush with the lowermost first placement plate 41.

[0055] The control component 62 includes a reset spring 621, a first slide bar 622, a second slide bar 623, and a control spring 624.

[0056] A return spring 621 is arranged along the sliding direction of the clamping plate 61 and its two ends are respectively connected to the clamping plate 61 and the first placement plate 41. A first slide rod 622 is slidably connected to the first placement plate 41 along a sliding direction parallel to the clamping plate 61. A control spring 624 is arranged along the sliding direction of the clamping plate 61 and its two ends are respectively connected to the first slide rod 622 and the first placement plate 41. A second slide rod 623 is slidably connected to the first placement plate 41 along a direction perpendicular to the clamping plate 61 and its two ends abut against the first slide rod 622 and the clamping plate 61, respectively.

[0057] In addition, such as Figure 3 and Figure 4 As shown, the release component 63 includes a mounting rod 631 and a release block 632. The mounting rod 631 is mounted on the support frame 1 and located on the side of the first placement plate 41 opposite to the second placement plate 42. The release block 632 is mounted on the mounting rod 631. The upper end surface of the release block 632 is a first inclined surface 633 that slides against the first sliding rod 622, and the lower end surface is a second inclined surface 634 that slides against the first sliding rod 622. The first inclined surface 633 slopes downward in the direction close to the first placement plate 41, and the first inclined surface 633 and the second inclined surface 634 are symmetrically arranged. One end of the second sliding rod 623 is a third inclined surface 625 that slides against the first sliding rod 622, and the other end has a fourth inclined surface 626 that slides with the clamping plate 61. The third inclined surface 625 is inclined in the direction away from the first sliding rod 622 and away from the second placement plate 42, and the fourth inclined surface 626 and the third inclined surface 625 are symmetrically arranged.

[0058] Since the position of the release block 632 remains unchanged, when the transfer device is not working, the release block 632 is located below the lowest placement rack 4. At this time, the first slide bar 622 on the lowest first placement plate 41 is located above the release block 632.

[0059] When placing parts, the upper placement rack 4 needs to be lowered until the uppermost placement rack 4 moves to the position of the lowermost placement rack 4 when the transfer device is not working, and continues to move down, so that the first inclined surface 633 of the release block 632 slides against the first slide rod 622. The control spring 624 contracts and controls the second slide rod 623 to slide along the direction close to the clamping plate 61 through the third inclined surface 625. The second slide rod 623 pushes the clamping plate 61 to slide away from the second placement plate 42 through the fourth inclined surface 626. The return spring 621 extends to facilitate the placement of parts on the placement rack 4. Then the first belt 2 and the second belt 3 drive the placement rack 4 to rise, and new placement racks 4 continuously come into contact with the second inclined surface 634 of the release block 632. The clamping plate 61 slides away from the second placement plate 42. The worker places the parts in sequence on the placement racks 4 that come into contact with the release block 632.

[0060] When staff need to retrieve parts, they start from the parts on the bottom shelf 4. As the first belt 2 and the second belt 3 move the shelf 4 downwards, staff do not need to climb the transfer device to place or retrieve parts, thus speeding up the process and protecting staff safety.

[0061] After the parts are placed on the rack 4, in order to further limit the position of the parts, refer to Figure 1 and Figure 5 A first baffle 65 is provided on the upper surface of the first placement plate 41 along the sliding direction perpendicular to the clamping plate 61, and a second baffle 66 is provided on the side of the clamping plate 61 opposite to the first baffle 65. A lower pressure plate 64 is provided on the upper surface of the clamping plate 61, and the lower pressure plate 64 is located on the side of the clamping plate 61 directly opposite the second placement plate 42.

[0062] When the component is placed on the placement rack 4, the first sliding rod 622 abuts against the release block 632, the return spring 621 extends, and the clamping plate 61 drives the second baffle 66 and the lower pressure plate 64 to slide together away from the second placement plate 42. After the component is placed on the placement rack 4, the component abuts against the first baffle 65. Then, the placement rack 4 moves upward, causing the first sliding rod 622 to move away from the release block 632. The clamping plate 61 drives the second baffle 66 and the lower pressure plate 64 to slide together towards the second placement plate 42. The clamping plate 61 on the second placement plate 42 slides towards the first placement plate 41 until both the clamping plates 61 on the second placement plate 42 and the first placement plate 41 abut against the component. At this time, the second baffle 66 abuts against the component, thereby limiting the horizontal position of the component. At this time, the lower end face of the lower pressure plate 64 abuts against the component, thereby limiting the vertical position of the component through the lower pressure plate 64, the first placement plate 41, and the second placement plate 42. This reduces the overall probability of parts shaking or even falling off the placement rack 4.

[0063] The implementation principle of the component processing and transfer device in this application embodiment is as follows: When picking up or placing components, the drive motor 51 can drive the first belt 2 and the second belt to rotate synchronously in opposite directions, thereby driving the placement rack 4 to rise or fall. The placement rack 4 located at the top can move downward, so that the workers can pick up or place the components located at the top without climbing the transfer device. The clamping plate 61 can limit the components, and when picking up or placing components, the clamping plate 61 can move away from the components through the sliding contact of the release block 632 and the first slide rod 622, so that the workers can pick up and place the components, ultimately improving the efficiency of picking up and placing large components on the transfer device and the safety factor of the workers when handling components on the transfer device.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
