Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a material conveying device and production equipment. Background Technology

[0002] In the field of electromechanical automation technology, especially in the processes of machinery manufacturing, electronic product assembly and automobile parts production, automatic conveying devices are commonly used to transport the workpieces to be processed sequentially to each processing device in order to achieve automated processing.

[0003] However, the processing methods of different processing devices in traditional technology are different, which results in different throughputs of workpieces per unit time for different processing devices, making it easy for workpieces to get stuck when they are transferred between different processing devices. Utility Model Content

[0004] Therefore, it is necessary to provide a material conveying device and production equipment to address the above problems.

[0005] This application provides a material conveying device, which includes a conveying component, a handling component, and a buffer component. The conveying component has multiple conveying channels for conveying workpieces, each of which extends along a first direction and is arranged side by side along a second direction, the first direction intersecting the second direction. The handling component includes a gantry and a pickup component. The gantry is mounted above the conveying component, and the pickup component is movably mounted on the gantry along the first and second directions. The buffer component is located at one end of the conveying component and is used for alignment with the processing channels. The buffer component includes a transport component for conveying the workpieces. The pickup component is used to pick up the workpieces conveyed by each of the conveying channels and transfer them to the buffer component.

[0006] In one embodiment, the transport assembly includes multiple transport components, each of which moves independently. There are multiple buffer components, each of which is aligned with a plurality of processing channels. The number of transport components is the same as the number of buffer components, so as to transfer the workpiece to the buffer components accordingly.

[0007] In one embodiment, the conveying component and the buffer component are arranged sequentially along the second direction, and the transport component further includes a first driver connected to the transport component to drive the transport component to move along the second direction, with different transport components having overlapping movement areas.

[0008] In one embodiment, the buffer assembly further includes blocking components, and a plurality of blocking components are correspondingly disposed at the ends of the plurality of buffer assemblies that are away from the conveying assembly; the buffer assembly has a buffer flow channel, and the blocking component includes a lifting driver and a first blocking member, the lifting driver being connected to the first blocking member and driving the first blocking member to move, the first blocking member being movable to a position aligned with and offset from the buffer flow channel.

[0009] In one embodiment, the conveying component and the buffer component may be configured to employ any one of belt conveying, friction wheel driven conveying, and roller conveying.

[0010] In one embodiment, the conveying assembly includes a first support and a conveying component, the conveying component being disposed on the first support and used to convey the workpiece; the number of the conveying components is multiple, the multiple conveying components extending along the first direction and arranged side by side in the second direction, each of the conveying components forming a conveying channel.

[0011] In one embodiment, the conveying assembly further includes a second blocking member, and a plurality of the second blocking members are correspondingly disposed at one end of each conveying channel near the buffer assembly, wherein the projection of the second blocking member along the first direction overlaps with the conveying channel.

[0012] In one embodiment, the conveying assembly further includes a first frame, a second frame, a first driver, a second driver, and a third driver; the first driver and the first frame are both disposed on the gantry, and the first driver is connected to the first frame to drive the first frame to move along the second direction; the second driver and the second frame are both disposed on the first frame, and the second driver is connected to the second frame to drive the second frame to move along the first direction; the third driver and the pickup are both disposed on the second frame, and a plurality of the third drivers are correspondingly connected to a plurality of the pickups to drive the pickups to move along a third direction, the third direction intersecting both the first direction and the second direction.

[0013] In one embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0014] This application also provides a production apparatus, which includes a processing device and a conveying device as described above. The processing device has a processing channel, and the conveying device is used to convey the workpiece to the conveying channel.

[0015] In the aforementioned conveying device, each conveying channel extends along a first direction and is arranged side-by-side along a second direction. Therefore, a pickup component is movably configured along both the first and second directions, allowing the pickup component to pick up the workpieces transported by each conveying channel and transfer them to the buffer assembly. Compared to directly transferring workpieces to the processing channel, the buffer assembly in this application allows for temporary placement of workpieces, and the carrying component of the buffer assembly can transport workpieces. Therefore, by intermittently controlling the carrying component to transport workpieces to the processing channel, the spacing between workpieces within the processing channel can be controlled, reducing the risk of multiple workpieces accumulating at one end of the processing channel near the conveying device and causing blockages, thus facilitating the orderly processing of each workpiece within the processing channel.

Detailed Implementation

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] Please see Figure 1 One embodiment of this application provides a production device, which includes a material conveying device and a processing device. The material conveying device can transfer workpieces to the processing device, and the processing device can process the workpieces. As one example, the processing device can perform processing steps on the workpieces, including but not limited to: inspection, cutting, turning, milling, drilling, assembly, welding, dispensing, spraying, coating, and performance testing.

[0035] Furthermore, the conveying device also has a flow channel integration function. That is, the conveying device can integrate workpieces conveyed by multiple flow channels into one or fewer flow channels. For example, if a processing device includes at least one processing flow channel, the conveying device can integrate workpieces conveyed by multiple flow channels into the processing flow channel, facilitating orderly processing by the processing device.

[0036] like Figure 1 In one embodiment, the production equipment may further include a pre-processing device, which can transfer the workpieces to be processed to a conveying device, and then from the conveying device to the processing device. The pre-processing device can pre-treat the workpieces for processing by the processing device. For example, if the processing device is used to inspect the workpieces, the pre-processing device can be configured as a dust removal device. Dust removal before workpiece inspection can improve the accuracy and reliability of the inspection. Since the pre-processing device can perform dust removal on a batch of workpieces (i.e., its throughput per unit time is relatively larger), it is usually equipped with multiple flow channels to transport workpieces in batches. For the processing device, inspection requires higher accuracy, so it typically has only one or a few flow channels (i.e., its throughput per unit time is relatively smaller). In this application, the conveying device is configured with a flow channel integration function, thus integrating the workpieces transported by the multiple flow channels of the pre-processing device into a relatively small number of flow channels at the inspection device, reducing the risk of material blockage. Of course, the processing device is not limited to inspecting workpieces. At the same time, the conveying device is not limited to receiving workpieces transferred by the pre-processing device. For example, the conveying device can also be used to receive workpieces transferred by other equipment.

[0037] It should be noted that the conveying device is not limited to integrating workpieces transported from multiple flow channels into a smaller number of flow channels; the conveying device can also be used to integrate workpieces transported from one or more flow channels into a larger number of flow channels. For example, the conveying device can also be arranged between a processing unit and another processing unit.

[0038] Please see Figure 2 and Figure 3 The material conveying device 10 provided in one embodiment of this application includes a conveying component 100, a transport component 200 and a buffer component 300. The transport component 200 can transport the workpiece 20 from the conveying component 100 to the buffer component 300.

[0039] The conveying assembly 100 has multiple conveying channels 101 for conveying workpieces 20. The number of conveying channels 101 corresponds to the number of channels in the pre-processing device, so as to receive the workpieces 20 transferred by the pre-processing device. Figure 3Each conveying channel 101 extends along a first direction S1 and is arranged side-by-side along a second direction S2, where the first direction S1 and the second direction S2 intersect. (See also...) Figure 4 Combined Figure 2 The conveying assembly 200 includes a gantry 210 and a pickup 220. The pickup 220 is used to pick up workpieces 20 and is movably disposed on the gantry 210 along a first direction S1 and a second direction S2. A buffer assembly 300 is located at one end of the conveying assembly 100 and is used for alignment with the processing flow path. The buffer assembly 300 includes a transport component 320 for transporting workpieces 20. The pickup 220 is used to pick up workpieces 20 transported by each transport flow path 101 and transfer them to the buffer assembly 300.

[0040] In the aforementioned material conveying device 10, each conveying channel 101 extends along the first direction S1 and is arranged side by side along the second direction S2. Therefore, the picking member 220 is movably configured along the first direction S1 and the second direction S2, so that the picking member 220 can pick up the workpiece 20 transported by each conveying channel 101 and transfer it to the buffer assembly 300. Compared to directly transferring the workpiece 20 to the processing channel, the buffer assembly 300 in this application can provide temporary placement for the workpiece 20, and the carrying component 320 of the buffer assembly 300 can transport the workpiece 20. Therefore, by intermittently controlling the carrying component 320 to transport the workpiece 20 to the processing channel, the spacing of the workpieces 20 in the processing channel can be controlled, reducing the risk of multiple workpieces 20 being stuck at one end of the processing channel near the material conveying device 10 and causing blockage, and facilitating the orderly processing of each workpiece 20 in the processing channel.

[0041] It is easy to understand that the pre-processing device and the processing device have different processing methods for workpiece 20, and their throughput of workpiece 20 per unit time differs, mainly due to the difference in the number of flow channels. This application sets up a conveying component 100 corresponding to the pre-processing device with a larger number of flow channels (larger throughput per unit time), and a buffer component 300 corresponding to the processing device with a smaller number of flow channels (smaller throughput per unit time). The workpiece 20 is transferred from the conveying component 100 to the buffer component 300 using the handling component 200, thus integrating the flow channels. Furthermore, configuring the buffer component 300 to temporarily store the workpiece 20 and intermittently transfer it to the processing flow channel reduces the risk of workpiece 20 blockage in the processing flow channel. This configuration allows devices with different throughput per unit time to transfer workpiece 20 without obstruction.

[0042] Furthermore, since the gantry 210 is mounted above the conveying assembly 100, the overall space occupied by the handling assembly 200 in the conveying direction of the workpiece 20 is small, leaving space for the buffer assembly 300. In other words, by combining the handling assembly 200 in the form of a gantry 210 with the buffer assembly 300, the workpiece 20 can be transferred without obstruction while occupying less space, making it easier for integrated design.

[0043] Please see Figure 3 In one embodiment, the number of cache components 300 can be configured according to the number of processing channels. As one example, there are multiple cache components 300, each corresponding to a multiple processing channels.

[0044] Please see Figure 4 In one embodiment, the transport assembly 200 includes a plurality of transport components 201, each of which moves independently. The number of transport components 201 is the same as the number of buffer assemblies 300, so as to transfer the workpiece 20 to each buffer assembly 300 accordingly. Configuring multiple independently moving transport components 201 to transport the workpiece 20 to each buffer assembly 300 respectively can improve the workpiece 20 transfer efficiency.

[0045] In one embodiment, the number of pickup elements 220 is the same as the number of conveyor channels 101. Therefore, the handling assembly 200 can batch transfer workpieces 20 to be picked up at each conveyor channel 101, resulting in high transfer efficiency. Each handling component 201 includes at least one pickup element 220 to further improve the workpiece 20 transfer efficiency. It should be noted that the pickup element 220 may include a mounting plate and multiple suction cups disposed on the mounting plate. The pickup element 220 can use multiple suction cups to jointly adsorb the workpiece 20 to achieve the purpose of picking up the workpiece. The statement that the number of pickup elements 220 is the same as the number of conveyor channels 101 refers to the total number of pickup elements 220, not the number of suction cups.

[0046] Please see Figure 3 and Figure 4 As one example, the number of conveyor channels 101 is m, the number of buffer components 300, processing channels, and handling components 201 are all n, and the number of pick-up items 220 in a single handling component 201 is k, where m = k * n. Thus, multiple handling components 201 cooperate to transfer workpieces 20 in the pick-up position on all conveyor channels 101. Combined with... Figure 3Taking m=4 and n=2 as an example, there are 4 conveyor channels 101, 2 processing channels, and 2 buffer components 300, with each buffer component 300 corresponding to one of the 2 processing channels. At this time, each transport component 201 has 2 pick-up pieces 220, and there are also 2 transport components 201. Therefore, each transport component 200 can transfer a maximum of 4 workpieces at a time. The 4 pick-up pieces 220 pick up the workpieces 20 to be picked up from the 4 conveyor channels 101. Each transport component 201 transfers the workpieces 20 picked up by the 2 pick-up pieces 220 to the corresponding buffer component 300. The combination of two transport components 201 can achieve channel integration.

[0047] Please see Figure 3 In one embodiment, the conveying component 100 and the buffer component 300 are arranged sequentially along the second direction S2.

[0048] Please see Figure 4 In one embodiment, the transport assembly 200 further includes a first driver 250 connected to the transport component 201 to drive the transport component 201 to move along the second direction S2, so that the transport component 201 can move along the second direction to a position aligned with the conveying assembly 100, and to a position aligned with the buffer assembly 300, to facilitate the transfer of the workpiece 20.

[0049] In one embodiment, different transport components 201 have overlapping movement areas, meaning that any transport component 201 can move to a position aligned with each transport channel 101 to pick up the workpiece 20 in each transport channel 101 and transfer it to the buffer assembly 300. Therefore, when one of the processing channels malfunctions or requires maintenance, the workpiece 20 that should be transported to that processing channel can be uniformly transferred to another processing channel by another transport component 201, thus enabling maintenance without stopping the machine and ensuring efficiency.

[0050] In one embodiment, along the second direction S2, the conveying component 100 and the buffer component 300 have an overlapping area. For example... Figure 3 That is, the end of the buffer component 300 near the conveying component 100 can extend along the first direction S1 to the side of the conveying component 100. With this configuration, the pick-up component 220 can transfer the workpiece 20 to the buffer component 300 by moving laterally along the second direction S2. Therefore, it is not necessary to configure the pick-up component 220 to move along the first direction S1, which simplifies the structure.

[0051] In one embodiment, the first driver 250 may be configured as a multi-actuator linear motor module to independently drive the movement of each transport component 201 and allow each transport component 201 to have overlapping motion areas.

[0052] Please refer to it again. Figure 3In one embodiment, the material conveying device 10 includes a base 400, and the conveying component 100, the handling component 200 and the buffer component 300 are all disposed on the base 400.

[0053] Please see Figure 5 Combined Figure 3 In one embodiment, the conveying assembly 100 includes a first support 110 and a conveying component 120. The first support 110 is disposed on the base 400, and the conveying component 120 is disposed on the first support 110 and used to convey the workpiece 20. It is understood that the conveying component 120 extends along a first direction S1, and the conveying component 120 can carry the workpiece 20 to move along the conveying channel 101.

[0054] Please see Figure 5 In one embodiment, the buffer assembly 300 includes a second support 310 and a transport component 320. The second support 310 is disposed on the base 400, and the transport component 120 is disposed on the second support 310 and used to transport the workpiece 20. The buffer assembly 300 has a buffer flow channel 301, and the transport component 320 can transport the workpiece 20 along the buffer flow channel 301. The pick-up component 220 can pick up the workpiece 20 in the transport flow channel 101 and transfer it into the buffer flow channel 301. Further, the buffer assembly 300 can accommodate one or more workpieces 20.

[0055] Please see Figure 3 Combined Figure 5 and Figure 6 In one embodiment, the conveying assembly 100 and the buffer assembly 300 can be configured to use any one of belt conveying, friction wheel driven conveying, and roller conveying. That is, the conveying component 120 can transport the workpiece 20 along the conveying channel 101 by means of belt conveying, friction wheel driven conveying, or roller conveying. The carrying component 320 can transport the workpiece 20 along the buffer channel 301 by means of belt conveying, friction wheel driven conveying, or roller conveying.

[0056] Please see Figure 7 and Figure 8As one example, the conveying component 120 can convey the workpiece 20 via a friction wheel driven conveying method. In this case, the conveying component 120 includes a first shaft 121, a first friction wheel 122, a first transmission belt 123, and a first conveying driver 124. The first friction wheel 122 is fitted onto the first shaft 121 and is driveably connected to the first shaft 121. The first shaft 121 is rotatably engaged with the first support 110. The first conveying driver 124 is disposed on the first support 110 and is connected to the first shaft 121, used to drive the first shaft 121 to rotate. Multiple first shafts 121 are arranged side-by-side in a first direction S1 and extend in a direction intersecting the first direction S1. The first transmission belt 123 is driveably connected between adjacent first shafts 121, or the first transmission belt 123 is driveably connected between the first friction wheels 122 fitted onto adjacent first shafts 121. Therefore, when one of the first shafts 121 rotates under the drive of the first conveyor driver 124, it can drive the other first shafts 121 to rotate synchronously through the first transmission belt 123, causing each of the first friction wheels 122 to rotate synchronously. The first friction wheels 122 can contact the workpiece 20 and drive the workpiece 20 to be conveyed in the expected direction through contact friction.

[0057] Furthermore, the first shaft 121 may extend along the second direction S2. The first transmission belt 123 may be configured as a flat belt or a belt with a round cross-section.

[0058] Please see Figure 9 and Figure 10 As one example, the transport component 320 can also be driven by friction wheels. In this case, the transport component 320 includes a second shaft 321, a second friction wheel 322, a second transmission belt 323, and a second transport driver 324. The second friction wheel 322 is fitted onto the second shaft 321 and is driveably connected to the second shaft 321. The second shaft 321 is rotatably engaged with the second support 310. The second transport driver 324 is located on the second support 310 and is connected to the second shaft 321 to drive the second shaft 321 to rotate. Multiple second shafts 321 are arranged side by side in the second direction S2 and extend in a direction intersecting the second direction S2. The second transmission belt 323 is driveably connected between adjacent second shafts 321, or the second transmission belt 323 is driveably connected between the second friction wheels 322 fitted onto adjacent second shafts 321. Therefore, when one of the second shafts 321 rotates under the drive of the second conveyor driver 324, it can drive the other second shafts 321 to rotate synchronously via the second transmission belt 323, causing each of the second friction wheels 322 to rotate synchronously as well. The second friction wheels 322 can contact the workpiece 20 and drive the workpiece 20 to be conveyed in the desired direction through contact friction.

[0059] Furthermore, the second shaft 321 may extend along the second direction S2. The second drive belt 323 may be configured as a flat belt or a belt with a round cross-section.

[0060] In one embodiment, the first conveyor driver 124 and the first shaft 121 can be connected by a transmission method such as belt drive or gear drive, which will not be described in detail here. The second conveyor driver 324 and the second shaft 321 can also be connected by a transmission method such as belt drive or gear drive, which will not be described in detail here.

[0061] Of course, the conveying assembly 100 and the buffer assembly 300 can also convey the workpiece 20 in other ways. Taking the buffer assembly 300 as an example, when the buffer assembly 300 conveys the workpiece 20 via a belt, the carrying component 320 includes a first drive shaft (not shown, the same below), a second drive shaft (not shown, the same below), and a conveyor belt (not shown, the same below). One of the first drive shaft and the second drive shaft is connected to the second conveyor driver 324, and the conveyor belt is wrapped around the first drive shaft and the second drive shaft. Thus, when the second conveyor driver 324 drives one of the two drive shafts to move, it can drive the conveyor belt and the other to rotate, thereby conveying the workpiece 20.

[0062] As another example, when the buffer assembly 300 conveys the workpiece 20 via a roller conveyor, the transport component 320 includes multiple rollers (not shown in the figure, the same below) and a transmission component (not shown in the figure, the same below), with the transmission component connected between the multiple rollers. Furthermore, one of the rollers is connected to the second transport driver 324; therefore, when this roller rotates under the drive of the second transport driver 324, it can drive the other multiple rollers to rotate together via the transmission component, thus jointly conveying the workpiece 20.

[0063] Please see Figure 5 Combined Figure 3 In one embodiment, there are multiple conveying components 120, which extend along a first direction S1 and are arranged side-by-side in a second direction S2. Each conveying component 120 forms a conveying channel 101. In this embodiment, since each conveying component 120 forms a conveying channel 101, each conveying component 120 can independently drive the workpiece 20 within its respective conveying channel 101 without affecting each other. Therefore, when the workpiece 20 in any conveying channel 101 moves to a position where it can be picked up by the pickup component 220, the conveying component 120 can stop conveying, so that the workpiece 20 is stably in the pickup position. For example, a sensor can be configured to be connected to a first conveying driver 124. When the sensor senses that the workpiece 20 has arrived, it sends a stop driving signal to the first conveying driver 124.

[0064] Furthermore, there can be multiple first supports 110, with each first support 110 corresponding to a multiple transport component 320. Alternatively, multiple transport components 320 can be located on the same first support 110.

[0065] Of course, the conveying assembly 100 is not limited to forming multiple conveying channels 101 in a one-to-one correspondence with multiple conveying components 120. For example, in one embodiment, the conveying components 120 still extend along the first direction S1. The conveying assembly 100 also includes a flow divider (not shown in the figure, the same below), with multiple flow dividers extending along the first direction S1 and spaced apart in the second direction S2. Adjacent flow dividers and conveying components 120 enclose each other to form conveying channels 101. That is, each conveying channel 101 can share the same conveying component 120, and the conveying area of ​​the conveying component 120 is divided by the flow divider to form multiple parallel conveying channels 101. At this time, each conveying channel 101 conveys the workpiece 20 synchronously.

[0066] Please see Figure 10 Combined Figure 6 In one embodiment, the buffer assembly 300 further includes blocking members 330, with multiple blocking members 330 correspondingly disposed at the ends of the multiple buffer assemblies 300 away from the conveying assembly 100. In other words, the blocking members 330 are located downstream of the conveying assembly 320 in the conveying direction. The blocking member 330 includes a lifting driver 331 and a first blocking member 332. The lifting driver 331 is connected to the first blocking member 332 and drives the first blocking member 332 to move. The first blocking member 332 can move to a position aligned with and offset from the buffer channel 301. Thus, when the buffer assembly 300 is used to temporarily place the workpiece 20, the first blocking member 332 can be operated to rise and align with the buffer channel 301. At this time, the first blocking member 332 can prevent the workpiece 20 from being conveyed downstream, further reducing the risk of material blockage. It is easy to understand that when there is sufficient space in the processing channel to receive the workpiece 20, the first descent can be operated to open the buffer channel 301.

[0067] The alignment of the first blocking member 332 with the buffer channel 301 refers to the fact that the orthographic projection of the first blocking member 332 along the extension direction of the buffer channel 301 overlaps with the buffer channel 301. Furthermore, the buffer channel 301 can extend along the first direction S1, meaning the alignment refers to the fact that the orthographic projection of the first blocking member 332 along the first direction S1 overlaps with the buffer channel 301. Even further, the lifting driver 331 can drive the first blocking member 332 to directly extend into the buffer channel 301 to align with it.

[0068] Please see Figure 7 and Figure 8 Combined Figure 5In one embodiment, the conveying assembly 100 further includes second blocking members 130. Multiple second blocking members 130 are correspondingly disposed at the end of each conveying channel 101 near the buffer assembly 300, that is, at the downstream end of the conveying channel 101. The projection of the second blocking member 130 along the first direction S1 overlaps with the conveying channel 101. Therefore, the second blocking member 130 can prevent the workpiece 20 conveyed by the conveying component 120 from continuing to move downstream.

[0069] Understandably, when the conveying assembly 100 includes multiple independently start-stop conveying components 120, the second blocking member 130 can serve as a safety protection measure to reduce the risk of the workpiece 20 falling off the conveying component 120 due to sensor malfunction or accidental start-up of the conveying component 120. When the conveying assembly 100 includes the aforementioned diverter plate, the second blocking member 130 can be used to limit the position of the workpiece 20, keeping it stably in the position to be picked up.

[0070] Please see Figure 11 In one embodiment, the transport component 201 includes a first frame 230, a second frame 240, a pickup 220, a second driver 260, and a third driver 270. That is, the transport assembly 200 includes a pickup 220, a gantry 210, a first frame 230, a second frame 240, a first driver 250, a second driver 260, and a third driver 270.

[0071] The first driver 250 and the first frame 230 are both mounted on the gantry 210. The first driver 250 is connected to the first frame 230 to drive the first frame 230 to move along the second direction S2. The second driver 260 and the second frame 240 are both mounted on the first frame 230. The second driver 260 is connected to the second frame 240 to drive the second frame 240 to move along the first direction S1. The third driver 270 and the pickup 220 are both mounted on the second frame 240. Multiple third drivers 270 are correspondingly connected to multiple pickups 220 to drive the pickups 220 to move along a third direction S3. The third direction S3 intersects both the first direction S1 and the second direction S2. In this embodiment, the pickup 220 can move closer to and further away from the conveying plane where the workpiece 20 is located by moving along the third direction S3, so as to pick up and place the workpiece 20. Figure 3 The pickup component 220 can move along the first direction S1 with the second frame 240, and the pickup component 220 can move along the second direction S2 with the first frame 230 and the second frame 240. Therefore, the pickup component 220 can flexibly move to the position aligned with the conveying component 100 and the position aligned with the buffer component 300 to realize the transfer of the workpiece 20.

[0072] In one embodiment, the first direction S1 may be perpendicular to the second direction S2. Further, the first direction S1, the second direction S2, and the third direction S3 are all perpendicular to each other.

[0073] Furthermore, the pickups 220 included in a single transport component 201 can be arranged at intervals along the second direction S2. Therefore, the pickups 220 move along the second direction S2 with the first frame 230 and the second frame 240, and different pickups 220 can be switched to align with the buffer component 300.

[0074] Taking two transport components 201 as an example, the transport assembly 200 may include a first transport component and a second transport component, with the first transport component and the second transport component having overlapping motion areas in the second direction S2. Thus, both the first transport component and the second transport component are capable of transferring the workpieces 20 within each transport channel 101 of the transport assembly 100.

[0075] It should be understood that the conveying device 10 can be applied between workstations where the throughput per unit time differs. For example, the conveying device 10 can be used to feed workpiece 20, in which case the conveying channel 101 is the feeding channel.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
