Technical Field
[0001] This utility model relates to the field of automation equipment technology, and in particular to a material conveying mechanism. Background Technology
[0002] In the processing industry, materials are usually transported between different workstations through material conveying mechanisms, so that the materials can move automatically between the workstations, thereby facilitating the processing and / or loading and unloading of workpieces.
[0003] Existing material conveying mechanisms typically carry materials directly. When conveying materials, they can only transport materials from upstream to downstream workstations. When the materials arrive at the downstream workstation, a robotic arm is required to remove the materials from the material conveying mechanism, which increases the demand for robotic arms and leads to higher production costs. Utility Model Content
[0004] The purpose of this utility model is to provide a material conveying mechanism to solve the problem that the material conveying mechanism in the prior art needs to be used in conjunction with a robotic arm for loading and unloading, which increases the demand for robotic arms and leads to higher production costs.
[0005] This utility model provides a material conveying mechanism, which includes:
[0006] frame;
[0007] A guide rail is mounted on the frame and extends along a first direction;
[0008] A pusher frame is slidably connected to the frame along a first direction. The pusher frame is located above the guide rail. The pusher frame is provided with a material receiving groove and an opening communicating with the material receiving groove. The opening is opened along the first direction, and the opening allows material located in the material receiving groove to pass through along the first direction.
[0009] A stop is movably disposed on the pusher frame, the stop being movable relative to the pusher frame to open the opening or at least partially close the opening, and when the stop at least partially closes the opening, the stop prevents material located in the receiving trough from passing through the opening.
[0010] As a preferred technical solution for the material conveying mechanism, the material conveying mechanism includes two stops, which are arranged opposite to each other on both sides of the opening along a second direction, and both stops are movably connected to the pusher frame, and each stop can close the opening portion.
[0011] As a preferred technical solution for the material conveying mechanism, the stop and the pusher are rotatably connected by a rotating shaft. The material conveying mechanism also includes a torsion spring, which is sleeved on the rotating shaft. The two torsion arms of the torsion spring abut against the pusher and the stop respectively. When the stop closes the opening, the pusher and the stop abut against each other in the first direction, and the torsion spring drives the stop to close the opening.
[0012] As a preferred technical solution for the material conveying mechanism, the pusher includes a frame, two adjusting plates, and two limiting seats. Both adjusting plates are connected to the frame, and the relative positions of the two adjusting plates and the frame along the second direction are adjustable. The two limiting seats are connected to the two adjusting plates one-to-one. The material receiving trough and the opening are both provided on the frame. The two stops are movably connected to the two limiting seats respectively, and when the stop closes the opening, the stop and the corresponding limiting seat abut against each other along the first direction.
[0013] As a preferred technical solution for the material conveying mechanism, the frame includes a first frame and a second frame, the first frame and the second frame are connected, and the relative position of the first frame with respect to the second frame along the second direction is adjustable. The first frame and the second frame enclose the material receiving trough and the opening, and the two adjusting plates are respectively connected to the first frame and the second frame.
[0014] As a preferred technical solution for the material conveying mechanism, the guide rail includes two linear rails that are parallel and spaced apart along the second direction, and both linear rails extend along the first direction;
[0015] The linear guide includes a vertically connected support surface and a limiting surface, and the limiting surfaces of the two linear guides limit the position of the material along the second direction.
[0016] As a preferred technical solution for the material conveying mechanism, the material conveying mechanism further includes a drive component mounted on the frame and a connecting block fixedly connected to the pusher frame, wherein the drive component and the connecting block are connected in a transmission manner.
[0017] As a preferred technical solution for the material conveying mechanism, the material conveying mechanism further includes a slide rail fixedly installed on the frame and a slider slidably connected to the slide rail. The slide rail extends along the first direction, and the pusher frame is fixedly connected to the slider.
[0018] As a preferred technical solution for the material conveying mechanism, the material conveying mechanism further includes a first sensor and a second sensor, both installed on the frame, and a detection component fixedly connected to the pusher frame.
[0019] As a preferred technical solution for the material conveying mechanism, the material conveying mechanism further includes a first damper and a second damper both installed on the frame. The first damper and the second damper are spaced apart along the first direction, and the first damper and the second damper limit the sliding range of the connecting block relative to the frame.
[0020] The material conveying mechanism provided by this utility model has at least the following beneficial effects:
[0021] When this material conveying mechanism needs to convey materials, the materials are placed in the receiving trough of the pusher frame and supported by the guide rail. The stopper closes the opening at least partially. By pushing the pusher frame, the materials move synchronously along the guide rail. When the materials are conveyed to the appropriate position, the stopper opens the opening and pushes the pusher frame back. The materials can exit the receiving trough through the opening, allowing the materials and the pusher frame to separate automatically. There is no need to equip a robotic arm to handle the materials, which can effectively reduce production costs. Attached Figure Description

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0042] Existing material conveying mechanisms typically carry materials directly. When conveying materials, they can only transport materials from upstream to downstream workstations. When the materials arrive at the downstream workstation, a robotic arm is required to remove the materials from the material conveying mechanism, which increases the demand for robotic arms and leads to higher production costs.
[0043] To address this issue, this embodiment provides a material conveying mechanism. This mechanism is used to convey materials. In this embodiment, the material can switch positions between a loading station, a processing station, and a unloading station under the conveying action of the mechanism. Of course, in other embodiments, the material can also switch between a first processing station, a second processing station, and a third processing station, depending on actual needs.
[0044] Specifically, please refer to Figures 1 to 6 The material conveying mechanism includes a frame 1, a guide rail 2, a pusher frame 3, and a stop 4. The frame 1 is used for installation on external equipment such as an assembly line, and the guide rail 2 is installed on the frame 1, with the guide rail 2 along a first direction (e.g., Figure 1 Extending in the direction indicated by the middle arrow ab), the guide rail 2 is used to support the material; the pusher frame 3 is slidably connected to the frame 1 along the first direction, the pusher frame 3 is located above the guide rail 2, the pusher frame 3 is provided with a material receiving groove 31 and an opening 32 communicating with the material receiving groove 31, the material receiving groove 31 is used to receive the material, the opening 32 is opened along the first direction, and the opening 32 allows the material in the material receiving groove 31 to pass through along the first direction; the stop 4 is movably disposed on the pusher frame 3, the stop 4 can move relative to the pusher frame 3 to open the opening 32 or at least partially close the opening 32, and when the stop 4 at least partially closes the opening 32, the stop 4 can prevent the material in the material receiving groove 31 from passing through the opening 32.
[0045] The material conveying mechanism provided in this embodiment has a pusher 3 that can move relative to the frame 1 to have a first position and a second position, and a stop 4 that can move relative to the frame 1 to have an open position that opens the opening 32 and a closed position that at least partially closes the opening 32. The material, conveyed by the material conveying mechanism, has a feeding position and a processing position. Figure 1 As shown, the pusher 3 is initially in the first position, and the stop 4 is in the closed position; as Figure 2 As shown, the material is placed in the receiving trough 31 of the pusher 3 located in the first position, and the material is supported by the guide rail 2. At this time, the material is in the feeding position; then the pusher 3 is pushed to the second position along the first direction. During this process, the pusher 3 will push the material to move synchronously along the guide rail 2; as shown Figure 3 As shown, when the pusher 3 reaches the second position, the material reaches the processing position, causing the stop 4 to switch to the open position, and then driving the pusher 3 back to the first position; as shown Figure 4 As shown, as the pusher 3 moves, when the pusher 3 moves to the first position, the material will pass through the opening 32 and exit the receiving trough 31, realizing the automatic separation of the material and the pusher 3. Therefore, there is no need to equip a robotic arm to handle the material, which can effectively reduce production costs.
[0046] In this embodiment, when the pusher 3 is in the first position, the material can be moved to the loading position using a robotic arm and a lifting mechanism. Of course, in other embodiments, the material can also be moved to the loading position manually as needed.
[0047] In this embodiment, the material container 31 is along the vertical direction (e.g., Figure 1 The material trough 31 is opened in the direction indicated by the middle arrow cd, and the material trough 31 passes through the pusher frame 3; in other embodiments, the material trough 31 can also be set as a blind trough opened in the vertical direction, and the opening of the material trough 31 faces downward, so as to allow the material to extend into the material trough 31.
[0048] Furthermore, the materials can be configured according to the needs of the actual processing situation. In this embodiment, an exemplary scheme is provided in which the materials include a carrier 15 and a workpiece positioned on the carrier 15. In this case, the material conveying mechanism directly conveys the carrier 15 and drives the workpiece positioned on the carrier 15 to move synchronously, enabling the workpiece to switch between different workstations, so as to facilitate the processing and transportation of the workpiece.
[0049] In other embodiments, the material can also be set as an empty carrier. In this case, the material conveying mechanism is only used to transport the empty carrier. This is suitable for situations where the empty carrier needs to be moved from the rear station to the front station after the product is processed, which facilitates the reuse of the empty carrier. The material can also be set as the workpiece to be processed, especially irregularly shaped workpieces or large workpieces. The workpiece can be directly supported and transported by the material conveying mechanism, so that the workpiece can be switched between different stations. This also facilitates the processing and transportation of the workpiece.
[0050] Alternatively, please refer to Figure 4 The material also has a discharge position located downstream of the working position. This material conveying mechanism can not only transport material from the loading position to the working position, but also transport material located at the working position to the discharge position, thereby further improving the conveying capacity of the material conveying mechanism. Specifically, when the material conveying mechanism transports the first material to the working position and the pusher 3 returns to the first position, the stop 4 switches back to the closed position; for example... Figure 5 As shown, the second material is loaded into the feeding position, and then the pusher 3 is pushed to the second position. During this process, the stop 4 will contact the first material located in the working position and push the material to continue moving in the first direction; as shown Figure 6 and Figure 7 As shown, when the pusher 3 reaches the second position, the first material is pushed to the unloading position, and the workpiece of the first material can be unloaded. At the same time, the second material is in the working position, which is convenient for processing the workpiece of the second material. Therefore, the material conveying mechanism can switch between the loading position, the processing position and the unloading position, which effectively reduces equipment investment and production costs.
[0051] Optionally, in this embodiment, when the stop 4 is in the closed position, the stop 4 partially closes the opening 32. In other embodiments, when the stop 4 is in the closed position, the stop 4 may also completely close the opening 32.
[0052] Alternatively, please refer to Figure 8 The material conveying mechanism includes two stops 4, which are positioned along a second direction (e.g., Figure 1The two stops (in the direction indicated by the arrow ef) are positioned opposite each other on both sides of the opening 32, and both stops are movably connected to the pusher frame 3. Each stop 4 can partially close the opening 32. This arrangement ensures the stability of the material movement when the stops 4 push the first material to the lower position. Specifically, in this embodiment, the opening 32 is closed together by the cooperation of the two stops 4. The opening 32 can be completely closed by the two stops 4, or it can be partially closed by the two stops 4, as long as the distance between the two stops 4 along the second direction is less than the dimension of the material along the second direction when the two stops 4 are in the closed position. In this embodiment, the first direction, the second direction, and the vertical direction are mutually perpendicular. In other embodiments, the first direction and the second direction can be set at an angle, and both the first direction and the second direction are perpendicular to the vertical direction.
[0053] Alternatively, please refer to Figure 9 The stop 4 and the pusher 3 are rotatably connected by the rotating shaft 5. The material conveying mechanism also includes a torsion spring 6, which is sleeved on the rotating shaft 5. The two torsion arms 61 of the torsion spring 6 abut against the pusher 3 and the stop 4 respectively. When the stop 4 partially closes the opening 32, the pusher 3 and the stop 4 abut against each other in the first direction and the torsion spring 6 drives the stop 4 to partially close the opening 32. With this configuration, when the pusher 3 returns from the second position to the first position, the stop 4 will come into contact with the material and, under the force exerted by the material, will automatically switch from the closed position to the open position, allowing the material to gradually exit the receiving trough 31 through the opening 32. After the material exits the receiving trough 31 through the opening 32, the stop 4 can automatically switch to the closed position under the drive of the torsion spring 6. When the pusher 3 moves from the first position to the second position again, the stop 4 in the closed position will come into contact with the material in the working position, and the pusher 3 will hold the stop 4, so that the forward force of the pusher 3 is transmitted to the material in the working position through the stop 4, thereby pushing the material in the working position to the lower material position.
[0054] In other embodiments, a first motor can be used instead of the torsion spring 6. The first motor can be fixedly mounted on the pusher frame 3. The first motor is connected to the stop 4 in a transmission connection, and the stop 4 is driven by the first motor to switch between the open position and the closed position.
[0055] As an alternative, the stop 4 can also be slidably connected to the pusher 3. The stop 4 can slide relative to the pusher 3 and switch between the closed position and the open position. The stop 4 can be switched between the closed position and the open position by the second motor.
[0056] Alternatively, please refer to Figure 9The pusher rack 3 includes a frame 33, two adjusting plates 34, and two limiting seats 36. Both adjusting plates 34 are connected to the frame 33, and their relative positions along a second direction are adjustable. The two limiting seats 36 are connected to the two adjusting plates 34 one-to-one. A material receiving trough 31 and an opening 32 are both located on the frame 33. Two stops 4 are movably connected to the two limiting seats 36. When a stop 4 is in the closed position, it abuts against the corresponding limiting seat 36 along a first direction. This configuration allows adjustment of the distance between the two stops 4 by adjusting the relative positions of the adjusting plates 34 to the frame 33 along the second direction, thereby adjusting the degree to which the two stops 4 close the opening 32 when in the closed position, facilitating the handling of different types of materials.
[0057] Specifically, in this embodiment, the adjusting plate 34 is provided with a first oblong hole 341, which extends along a second direction. A first bolt 35 passes through the first oblong hole 341 and is threadedly connected to the frame 33. When the first bolt 35 is loosened, the adjusting plate 34 can be moved along the second direction to adjust the relative position of the adjusting plate 34 and the frame 33. When the first bolt 35 is tightened, the relative position of the adjusting plate 34 and the frame 33 can be locked. In other embodiments, multiple first through holes can be provided on the adjusting plate 34, which are spaced apart along the second direction. The first bolt 35 passes through one of the first through holes and is threadedly connected to the frame 33.
[0058] Alternatively, please refer to Figure 10 The frame 33 includes a first frame 331 and a second frame 332, which are connected. The relative position of the first frame 331 to the second frame 332 along a second direction is adjustable. The first frame 331 and the second frame 332 form a material receiving trough 31 and an opening 32. Two adjusting plates 34 are respectively connected to the first frame 331 and the second frame 332. This arrangement facilitates adjustment of the size of the material receiving trough 31 along the second direction to accommodate different types of materials.
[0059] Specifically, in this embodiment, a second oblong hole 333 is provided on the first frame 331. The second oblong hole 333 extends along a second direction. A second bolt passes through the second oblong hole 333 and is threadedly connected to the second frame 332. When the second bolt is loosened, the first frame 331 can be moved along the second direction to adjust the relative position of the first frame 331 and the second frame 332. When the second bolt is tightened, the relative position of the first frame 331 and the second frame 332 can be locked. In other embodiments, multiple second through holes can be provided on the first frame 331. The multiple second through holes are spaced apart along the second direction. A second bolt passes through one of the second through holes and is threadedly connected to the second frame 332.
[0060] Alternatively, please refer to Figure 8 and Figure 10 The frame 33 also includes two push blocks 334, which are connected to the first frame 331 and the second frame 332 respectively, and are located below the first frame 331 and the second frame 332. When the pusher 3 pushes the material, it contacts the material through the two push blocks 334 and provides power to the material. In other embodiments, the material can also be pushed by the wall of the material receiving tank 31.
[0061] Alternatively, please refer to Figures 1 to 6 The guide rail 2 includes two parallel and spaced linear rails 21 arranged along a second direction, both extending along a first direction. Each linear rail 21 includes a vertically connected support surface 211 and a limiting surface 212. The support surface 211 supports the material, and the limiting surfaces 212 of the two linear rails 21 restrict the position of the material along the second direction. Specifically, when the material is supported on the guide rail 2, the carrier 15 is supported by the two support surfaces 211, and the carrier 15 is located between the two limiting surfaces 212. The two limiting surfaces 212 restrict the position of the material along the second direction. This arrangement ensures that the material's movement direction remains stable when the pusher 3 pushes the material to slide along the guide rail 2. Preferably, the relative position of at least one guide rail 2 with respect to the frame 1 along the second direction is adjustable to accommodate different types of materials.
[0062] It should be noted that the linear guide 21 can be set as a whole, or it can be spliced from multiple sections according to actual needs. When splicing, adjacent sections can abut against each other or be spaced a certain distance apart, as long as the material can be smoothly moved from one section to the next adjacent section.
[0063] Alternatively, please refer to Figures 1 to 6 ,as well as Figure 8 and Figure 10 The material conveying mechanism also includes a drive component 7 mounted on the frame 1 and a connecting block 16 fixedly connected to the pusher frame 3. The drive component 7 and the connecting block 16 are connected in a transmission manner. Specifically, the drive component 7 drives the connecting block 16 and drives the pusher frame 3 to move synchronously along the first direction, thereby realizing automatic material conveying. Of course, in other embodiments, the material rack can also be manually driven to convey materials along the first direction as needed.
[0064] In this embodiment, the driving component 7 is specifically a rodless cylinder. In other embodiments, the driving component 7 may also be a rod-type cylinder, a hydraulic cylinder, or an electric cylinder.
[0065] Alternatively, please refer to Figure 3The material conveying mechanism also includes a slide rail 8 fixedly mounted on the frame 1, and a slider 9 slidably connected to the slide rail 8. The slide rail 8 extends along a first direction, and the pusher frame 3 is fixedly connected to the slider 9. By setting the slide rail 8 and the slider 9, the pusher frame 3 can be ensured to slide smoothly relative to the frame 1. Preferably, the material conveying mechanism includes two slide rails 8 and two sliders 9. Both slide rails 8 are fixedly mounted on the frame 1, and the two slide rails 8 are parallel and spaced apart along a second direction. Two linear rails 21 are located between the two slide rails 8, and the two sliders 9 are slidably connected to the two slide rails 8 respectively. The first frame 331 and the second frame 332 are fixedly connected to the two sliders 9 respectively.
[0066] Alternatively, please refer to Figures 1 to 6 ,as well as Figure 8 and Figure 10 The material conveying mechanism also includes a first damper 10 and a second damper 11, both mounted on the frame 1. The first damper 10 and the second damper 11 are spaced apart along a first direction. The first damper 10 and the second damper 11 are used to limit the sliding range of the connecting block 16 relative to the frame 1. This arrangement ensures that the pusher 3 stops stably at the first position and the second position, thereby ensuring the positional accuracy of the material when it is in the working position and the unloading position.
[0067] Specifically, in this embodiment, the first damper 10 and the second damper 11 are both used to abut against the connecting block 16. In other embodiments, the first damper 10 and the second damper 11 can also be used to abut against the pusher frame 3.
[0068] Alternatively, please refer to Figure 8 The material conveying mechanism also includes a first sensor 12 and a second sensor 13, both mounted on the frame 1, and a detection element 14 fixedly connected to the pusher frame 3. Specifically, both the first sensor 12 and the second sensor 13 are used to detect the position of the detection element 14. When the pusher frame 3 is in the first position, the detection element 14 cooperates with the first sensor 12 and is separated from the second sensor 13; when the pusher frame 3 is in the second position, the detection element 14 cooperates with the second sensor 13 and is separated from the first sensor 12. This arrangement ensures that the drive unit 7 stably drives the pusher frame 3 to the first or second position.
[0069] Specifically, in this embodiment, both the first sensor 12 and the second sensor 13 can be photoelectric sensors. Taking the first sensor 12 as an example, the first sensor 12 includes a light receiver and a light emitter arranged at intervals and opposite to each other. When the pusher 3 is in the first position, the detection element 14 is located between the light receiver and the light emitter. The light receiver cannot receive the light emitted by the light emitter, causing the first sensor 12 to emit a first detection signal (such as a low level). When the pusher 3 leaves the first position, the detection element 14 leaves the space between the light emitter and the light receiver. The light receiver receives the light signal emitted by the light emitter, causing the first sensor 12 to emit a second detection signal (such as a high level). Therefore, when the first sensor 12 emits the first detection signal, it indicates that the pusher 3 is in the first position at this time, and the drive element 7 can be controlled to stop driving to ensure that the pusher 3 can be accurately stopped at the first position.
[0070] In other embodiments, the first sensor 12 and the second sensor 13 may also be configured as a contact switch, a Hall sensor, etc.
[0071] The working principle of the material conveying mechanism provided in this embodiment is as follows:
[0072] 1) Initially, the pusher 3 is in the first position, the first damper 10 abuts against the connecting block 16, and the stop 4 is in the closed position. At this time, the first material is placed into the loading position, so that the first material is in the material receiving trough 31 and supported by the guide rail 2. Then, the pusher 3 is pushed to the second position along the first direction by the drive component 7, at which time the first material reaches the processing position. Then, the pusher 3 is driven back to the first position by the drive component 7. When the first material comes into contact with the stop 4, the force exerted by the first material on the stop 4 can overcome the torque of the torsion spring 6, so that the stop 4 rotates to the open position, so that the first material and the pusher 3 gradually separate. When the first material exits from the material receiving trough 31, the stop 4 switches to the closed position under the action of the torsion spring 6. Finally, the pusher 3 returns to the first position, the first damper 10 abuts against the connecting block 16, and the first material stays in the working position.
[0073] 2) The second material is placed in the feeding position, so that the second material is located in the material receiving trough 31 and supported by the guide rail 2; then the pusher 3 is moved to the second position along the first direction by the drive component 7. When the stop 4 comes into contact with the first material, the stop 4 will push the first material to move synchronously. When the pusher 3 reaches the second position, the second damping 11 comes into contact with the connecting block 16, and the first material reaches the unloading position; then the pusher 3 is driven back to the first position by the drive component 7. When the second material comes into contact with the stop 4, the force exerted by the second material on the stop 4 can overcome the torque of the torsion spring 6, so that the stop 4 rotates to the open position, so that the second material and the pusher 3 gradually separate. When the second material exits from the material receiving trough 31, the stop 4 switches to the closed position under the action of the torsion spring 6; finally, the pusher 3 returns to the first position, and the first damping 10 comes into contact with the connecting block 16. The second material stays in the working position, and the first material stays in the unloading position.
