Abstract
Description
Technical Field
[0001] This application belongs to the field of parts processing and production equipment, specifically relating to workpiece transfer devices. Background Technology
[0002] In the manufacturing process of industrial products, the transfer of parts is a common and crucial step. Taking the transfer of sheet-like parts as an example, in actual production lines, it is often necessary to transfer these parts from one tray to another. At the same time, based on the needs of subsequent processing or assembly of the product, it is often required to change the orientation of the sheet-like parts during the transfer process, such as changing from a vertical orientation to a horizontal orientation.
[0003] Current methods primarily rely on manual operation, where each component is placed individually by hand. However, this manual approach has several drawbacks. Firstly, manual operation is inefficient, severely limiting production speed and output, making it difficult to meet the high-efficiency demands of large-scale industrial production. Secondly, the consistency and accuracy of manual operation are difficult to guarantee, easily leading to placement errors, resulting in product quality issues, increased defect rates, and higher production costs. Therefore, there is an urgent need for a component transfer and repositioning technology solution that can address these problems to improve production efficiency and product quality. Utility Model Content
[0004] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a workpiece transfer device that can realize batch transfer and reversal of workpieces, improve the transfer efficiency of workpieces, and ensure the consistency of transfer position, thereby improving the product processing quality.
[0005] To achieve the above objectives, this application provides a workpiece transfer device, including a first workpiece tray, a second workpiece tray, a transfer guide plate, and several reversing structures. The first workpiece tray has several vertical workpiece slots, the second workpiece tray has several horizontal workpiece slots, and the transfer guide plate has several guide channels extending through it. The two ends of each guide channel are respectively formed as a narrow end and a wide end. The narrow end is adapted to and can be aligned with the vertical workpiece slots, and the wide end is adapted to and can be aligned with the horizontal workpiece slots. The reversing structures are arranged in a one-to-one correspondence with the guide channels.
[0006] In some embodiments, the reversing structure is movably configured and sequentially passes through the transverse carrier groove and the guide channel.
[0007] In some embodiments, the reversing structure includes a guide ramp that is inclined toward the narrow end.
[0008] In some embodiments, the workpiece transfer device includes a transfer positioning plate movably disposed outside the second workpiece tray, and all the reversing structures are disposed on the transfer positioning plate.
[0009] In some embodiments, the two sides of the transfer guide plate and the transfer positioning plate facing each other have a positioning hole on one side and a pin on the other side that is inserted into the positioning hole.
[0010] In some embodiments, the number of vertical carrier slots is greater than the number of guide channels, and all the narrow-mouth ends are adapted to the corresponding portions of the vertical carrier slots.
[0011] In some implementations, the number of vertical carrier slots in the first direction is twice the number of guide channels.
[0012] In some embodiments, all of the guide channels are provided for half of the vertical component slots, and after the transfer guide plate is rotated 180°, the guide channels are provided for the remaining half of the vertical component slots.
[0013] In some embodiments, the transfer guide plate is further provided with a plurality of stops, the plurality of narrow ends being adapted to and aligned with portions of the vertical loading slots, and the plurality of stops being adapted to and aligned with the remaining vertical loading slots.
[0014] In some embodiments, a first boss is formed on the top of the first carrier disk and a first countersunk portion is formed on the bottom of the transfer guide plate, and the first boss is able to engage with the first countersunk portion.
[0015] And / or, the top of the transfer guide plate is formed with a second recessed portion, and the second carrier plate can be engaged with the second recessed portion.
[0016] Through the above technical solution, when using the workpiece transfer device of this application to transfer and reverse a large number of workpieces, for example, when it is necessary to convert vertically placed workpieces to horizontally placed workpieces, each workpiece can first be placed in multiple vertical slots of a horizontally arranged first workpiece carrier. Then, the transfer guide plate and the empty second workpiece carrier are stacked on top of the first workpiece carrier in sequence, so that the two ends of each guide channel, namely the wide end and the narrow end, are connected to the corresponding horizontal and vertical workpiece carrier slots, respectively. Next, the stacked fixture is rotated 180 degrees, so that the upper and lower positions of the first and second workpiece carriers are exchanged. Under the action of gravity, the workpieces located in the vertical workpiece slots can slide down along the guide channels to the horizontal workpiece slots. Under the guidance of the reversing structure, the workpieces in the vertical state can be converted to the horizontal state, thereby realizing the synchronous transfer and reversal of a large number of workpieces. Compared with the traditional manual transfer method, this transfer method can save labor costs, improve the transfer efficiency of workpieces, and ensure the consistency of workpiece placement, thereby improving the production and processing quality of products.

[0039] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0040] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.
[0041] like Figure 1 as well as Figures 5 to 8 As shown, an exemplary embodiment of this application provides a workpiece transfer device, which mainly includes a first workpiece tray 1, a second workpiece tray 2, a transfer guide plate 3, and several reversing structures 401. The first workpiece tray 1 has several vertical workpiece slots 101, allowing for the placement of multiple vertically oriented workpieces A, such as thin sheet workpieces or long strip workpieces. The second workpiece tray 2 has several horizontal workpiece slots 201, allowing for the placement of multiple horizontally oriented workpieces. The vertical and horizontal workpiece slots 101 and 201 can be either blind slots with non-through inner walls or through slots, as long as they can accommodate workpieces; this application does not limit this. For example, the inner circumferential wall of a through slot may have stepped protrusions for supporting workpieces. The transfer guide plate 3 has several guide channels 301 extending through it, with narrow ends 302 and wide ends 303 at both ends. The reversing structures 401 are arranged in a one-to-one correspondence with the guide channels 301. (Refer to...) Figure 1 The second workpiece tray 2, the transfer guide plate 3, and the first workpiece tray 1 can be stacked in sequence to form a combination, so that the two ends of each guide channel 301 are connected to the corresponding horizontal workpiece groove 201 and vertical workpiece groove 101 respectively. That is, the corresponding horizontal workpiece groove 201, wide end 303, narrow end 302 and vertical workpiece groove 101 are connected in sequence, thereby forming multiple workpiece transfer channels.
[0042] Therefore, when using the workpiece transfer fixture of this exemplary embodiment to reposition and transfer multiple workpieces, for example, when converting a workpiece in a vertically placed state to a horizontally placed state, multiple workpieces can be pre-placed in multiple vertical loading slots 101 of the first loading tray 1. To ensure workpiece stability, the first loading tray 1 can be in a horizontal position at this time. Then, the transfer guide plate 3 and the empty second loading tray 2 are sequentially stacked and covered on the first loading tray 1, forming a structure as shown in the example. Figure 1 The assembly shown is then rotated 180 degrees, causing the first and second carrier trays 1 and 2 to exchange positions. Under gravity, the workpieces in the vertical carrier slot 101 can enter the guide channel 301 from the narrow end 302 and slide out into the horizontal carrier slot 201 from the wide end 303. The wide end 303 provides sufficient space for the workpieces to swing and change direction. Simultaneously, guided by the reversing structure 401, the workpieces in the vertical position can be converted to the horizontal position, thus achieving synchronous transfer and reversal of large batches of workpieces. Compared with the traditional manual transfer method, this transfer method significantly saves labor costs, improves workpiece transfer efficiency, ensures the consistency of workpiece placement, and improves the processing quality of products in subsequent production processes.
[0043] It should be noted that the workpiece transfer fixture using this exemplary embodiment can also convert a workpiece in a horizontally placed state to a vertically placed state. This is consistent with the principle of the above-described transfer process. Simply place the workpiece in the horizontal loading slot 201 of the second loading tray 2 beforehand, then stack the transfer guide plate 3 and the first loading tray 1 in sequence, and then rotate it 180 degrees to export the workpiece placed in the horizontal loading slot 201 to the vertical loading slot 101 of the first loading tray 1, thereby completing the conversion of the workpiece from horizontal to vertical.
[0044] To improve the smoothness of workpiece reversal and increase the success rate of reversal, the inner peripheral wall of the guide channel 301 is formed with a guide inclined surface (not shown in the attached figure) that serves as the aforementioned reversing structure 401. This guide inclined surface can guide the workpiece to reverse direction. For example, when a workpiece in a vertical state slides down the guide channel 301, it contacts the guide inclined surface, causing the workpiece to adjust from a vertical state to an inclined state that matches the guide inclined surface. The workpiece then slides down into the transverse carrier groove 201 in this inclined state. Under the action of gravity, the workpiece eventually changes from an inclined state back to a transverse state.
[0045] It should be noted that the two ends of the guide channel 301 are set as a narrow end 302 and a wide end 303. The main purpose is to adapt to the slot sizes of the vertical carrier slot 101 and the horizontal carrier slot 201, so that the workpiece can be smoothly introduced into and out of the guide channel 301 through the narrow end 302 and the wide end 303. The aforementioned guide inclined surface can be set in the guide section between the narrow end 302 and the wide end 303. This application does not limit the specific shape and structure of the guide section, as long as it is ensured that the aforementioned guide inclined surface is located on the inner peripheral wall of the guide section during use.
[0046] In an optional or preferred embodiment, the reversing structure 401 is movably disposed and can be sequentially disposed between the transverse carrier groove 201 and the guide channel 301. For example, the reversing structure 401 can be formed as follows: Figure 4 The columnar directional structure shown is as follows: Figure 9 As shown, the reversing structure 401 may include a guide ramp 4011. When the reversing structure 401 passes through the guide channel 301, the guide ramp 4011 is located on the side of the guide channel 301 from the narrow end 302 to the wide end 303. Thus, when the workpiece falls from the narrow end 302 to the wide end 303, it can land on the guide ramp 4011 midway, causing the workpiece to be in an inclined state. At this time, the reversing structure 401 is then pulled out of the guide channel 301 and the transverse loading groove 201, so that the inclined workpiece lands in the transverse loading groove 201, and finally converts it to a transversely oriented state.
[0047] In other embodiments, the reversing structure 401 can also be a vertically extending push rod. The push rod is used to eccentrically support the workpiece, which can also make the falling workpiece be in an inclined state. The specific working principle can be referred to the above embodiments, and will not be repeated here.
[0048] In an optional or preferred embodiment, such as Figures 2 to 4 As shown, the workpiece transfer device includes a transfer positioning plate 4. The transfer positioning plate 4 is provided with the aforementioned reversing structure 401 and can be stacked on the second workpiece tray 2, so that the reversing structure 401 can be sequentially inserted into the transverse workpiece slot 201 and the guide channel 301. (See details...) Figure 3 The transfer positioning plate 4, the second carrier plate 2, the transfer guide plate 3, and the first carrier plate 1 can be stacked vertically and combined into one unit. After being rotated 180 degrees, as shown... Figure 4 As shown, the reversing structure 401 is inserted upward into the transverse carrier groove 201, thereby supporting and positioning the workpiece that slides into the transverse carrier groove 201, so that the workpiece can be maintained in an inclined state when it has not completely fallen into the transverse carrier groove 201. For example, the reversing structure 401 supports the edge of the workpiece, so that the workpiece is in an inclined state.
[0049] In an optional or preferred embodiment, one side of the transfer guide plate 3 and the transfer positioning plate 4 facing each other has a positioning hole 402, and the other side has a pin 304 that engages with the positioning hole 402. Figure 4 and Figure 6 As an example, the positioning hole 402 is provided at the bottom of the transfer positioning plate 4, and the pin 304 is provided at the top of the transfer guide plate 3. When the transfer positioning plate 4 is in the position... Figure 3 When the stacked components are placed on the second carrier disk 2, the positioning hole 402 can be aligned with the pin 304 for insertion, so that the transfer positioning plate 4 and the transfer guide plate 3 together hold the second carrier disk 2, and the transfer positioning plate 4 will not deviate or shake, thus effectively ensuring stability.
[0050] It should be noted that in this application, directional terms such as "up" and "down" refer to the vertical direction, i.e., the direction of gravity, while "horizontal" refers to the direction perpendicular to the vertical. During transfer, the workpiece slides based on its own weight; directional terms such as "top" and "bottom" refer to the direction of gravity. Figure 1 and Figure 2 The vertical direction is defined in the perspective: the part of the structure located above is the top, and the part located below is the bottom.
[0051] In an optional or preferred embodiment, the number of vertical loading slots 101 is greater than the number of guide channels 301, and the multiple narrow ends 302 are respectively adapted to and aligned with portions of the vertical loading slots 101. Thus, with the second loading tray 2, the transfer guide plate 3, and the first loading tray 1 arranged in a stacked manner, the multiple guide channels 301 are respectively aligned and connected to the multiple horizontal loading slots 201, and the multiple guide channels 301 are respectively aligned and connected to portions of the vertical loading slots 101. Therefore, when the workpiece transfer device is flipped, the workpieces in some of the vertical loading slots 101 can be transferred to the respective horizontal loading slots 201 along the corresponding guide channels 301, while the other part of the workpieces remain temporarily in the corresponding vertical loading slots 101, thereby realizing the transfer of workpieces from a multi-slot carrier to a fewer-slot carrier.
[0052] In an optional or preferred embodiment, as shown in Figure 1 In the first direction shown, the number of vertical carrier slots 101 is twice the number of guide channels 301. The specific arrangement is as follows (see reference). Figure 1 and Figure 2 Multiple vertical loading slots 101, multiple horizontal loading slots 201, and multiple guide channels 301 are arranged sequentially on their respective carriers along the first direction. With the second loading tray 2, the transfer guide plate 3, and the first loading tray 1 stacked vertically, the wide ends 303 of the multiple guide channels 301 are aligned and connected to the multiple horizontal loading slots 201 one by one, and the narrow ends 302 of the multiple guide channels 301 are aligned and connected to half of the vertical loading slots 101 one by one. Thus, after flipping the fixture, half of the workpieces can be transferred at a time, realizing batch transfer and reduction transfer of multiple workpieces. Furthermore, in the second direction, the number of vertical loading slots 101 is the same as the number of guide channels 301.
[0053] In other embodiments, reference is made to Figure 1 and Figure 2 The multiple vertical component slots 101, multiple horizontal component slots 201, and multiple guide channels 301 are all arranged along the second direction, i.e., in an array. The number of vertical component slots 101 arranged along the first direction is twice the number of horizontal component slots 201 and guide channels 301 arranged along the first direction. In this embodiment, both the first and second directions are directions on a horizontal plane and are perpendicular to each other.
[0054] In an optional or preferred embodiment, all guide channels 301 are provided for half of the vertical loading slots 101, and after the transfer guide plate 3 is rotated 180°, the guide channels 301 are provided for the remaining half of the vertical loading slots 101, so that after the flip tooling is flipped, the remaining half of the workpieces can be quickly transferred to the second loading tray 2 through each guide channel 301.
[0055] Furthermore, the transfer guide plate 3 also has multiple stops 307, multiple narrow ends 302 respectively adapting to and aligning with portions of the vertical loading slots 101, and multiple stops 307 respectively adapting to and aligning with the remaining portions of the vertical loading slots 101. Specifically, as Figure 9 and Figure 10 As shown, when all guide channels 301 correspond to half of the vertical loading slots 101, multiple stops 307 can be arranged alternately with multiple narrow ends 302 along the first direction. When the transfer guide plate 3 and the first loading tray 1 are stacked on top of each other, any adjacent stop 307 and narrow end 302 respectively connect with two adjacent vertical loading slots 101. Thus, after the flipping fixture is turned over, one of the two workpieces set in the two adjacent vertical loading slots 101 can enter the guide channel 301 from the narrow end 302, and the other can be blocked by the stop 307 to stay in the vertical loading slot 101, waiting for the next transfer or to enter another processing step for use. During the next transfer, simply rotate the first loading tray 1 180 degrees around the intersection of the first and second directions, and then close the transfer guide plate 3 and the second loading tray 2 again. This will align and connect the multiple vertical loading slots 101 carrying the remaining workpieces to the corresponding narrow ends 302, facilitating the transfer of the remaining workpieces.
[0056] To achieve accurate docking and positioning between the transfer guide plate 3 and the first carrier tray 1, a first protrusion 102 is formed on one of the top of the first carrier tray 1 and the bottom of the transfer guide plate 3, and a first recessed platform 305 is formed on the other. Figure 5 and Figure 7 For example, a first protrusion 102 is formed on the top of the first carrier tray 1, and a first recessed portion 305 is formed on the bottom of the transfer guide plate 3. When the transfer guide plate 3 is stacked and covered on the first carrier tray 1, the first protrusion 102 can engage with the first recessed portion 305 to achieve precise docking between the transfer guide plate 3 and the first carrier tray 1. In particular, it ensures that the narrow end 302 of the guide channel 301 can be aligned with and connected to the corresponding vertical carrier slot 101. Under the limiting effect of the first recessed portion 305, the transfer guide plate 3 and the first carrier tray 1 are not prone to misalignment, ensuring the stability of the subsequent flipping process.
[0057] Similarly, in order to achieve accurate docking and positioning between the second carrier tray 2 and the transfer guide plate 3, one of the tops of the second carrier tray 2 and the top of the transfer guide plate 3 is provided with a second protrusion, and the other is provided with a second recessed portion 306. The second protrusion can engage with the second recessed portion 306; or, as... Figure 1 and Figure 6As shown, a second recessed platform 306 is formed on the top of the transfer guide plate 3, and the second carrier tray 2 can be fitted into the second recessed platform 306. Therefore, when the second carrier tray 2 is placed on the transfer guide plate 3, the second carrier tray 2 and the transfer guide plate 3 can mutually limit each other, ensuring that the transverse carrier groove 201 can be aligned with the wide end 303 of the corresponding guide channel 301, and that the second carrier tray 2 and the transfer guide plate 3 are not prone to misalignment, ensuring the stability of the subsequent flipping process.
[0058] For ease of understanding, the following description, in conjunction with the above embodiments, further illustrates the workflow of using the workpiece transfer device of this application to simultaneously perform number reduction transfer, reversal and distance adjustment of multiple workpieces.
[0059] As an example, this mainly illustrates the working principle of a workpiece changing from a vertical to a horizontal orientation during the transfer process.
[0060] Step 1: Place multiple workpieces into the multiple vertical slots 101 of the first workpiece carrier 1;
[0061] Step 2: Place the transfer guide plate 3 with the narrow end 302 facing down and the wide end 303 facing up on the first carrier plate 1, so that the first boss 102 and the first countersunk 305 are interlocked, the narrow end 302 is aligned and connected with the corresponding vertical carrier groove 101, and the stop position 307 is aligned and sealed with the corresponding vertical carrier groove 101.
[0062] Step 3: Place the empty second loading tray 2 on the transfer guide plate 3. For example, two second loading trays 2 can be placed simultaneously as shown in the figure, so that the transverse loading slot 201 is aligned and connected with the corresponding wide end 303.
[0063] Step 4: Cover the second carrier plate 2 with the transfer positioning plate 4, and align the positioning hole 402 with the pin 304 for insertion, so that the transfer positioning plate 4 and the transfer guide plate 3 together clamp the second carrier plate 2, and the reversing structure 401 is inserted into the corresponding transverse carrier groove 201.
[0064] Step 5: Rotate the assembled workpiece transfer device 180 degrees so that half of the workpiece load falls onto the guide slope 4011 of the reversing structure 401.
[0065] Step 6: Lift the first carrier plate 1 and the transfer guide plate 3 at the same time, ensuring that they are still stacked. Then lift the second carrier plate 2 and separate it from the transfer positioning plate 4, so that the workpiece located on the inclined end face falls into the corresponding transverse carrier groove 201 and is converted to a transverse swing state, thereby completing the first subtraction transfer of the workpiece.
[0066] Step 7: Flip the first loading tray 1 and the transfer guide plate 3 that have been lifted 180 degrees, that is, reset them to the state described in Step 2 above;
[0067] Step 8: Take another empty second loading tray 2 and repeat steps 3 to 6 above to transfer the remaining half of the workpieces to the second loading tray 2, thereby completing the second subtraction of workpieces.
[0068] As can be seen, through the above transfer process, multiple workpieces placed on the first carrier tray 1 can be transferred in two stages, that is, half of the workpieces are transferred each time, thus reducing the number of workpieces to be transferred. At the same time, the transferred workpieces can be repositioned, and the spacing between each workpiece can be appropriately adjusted to meet the pick-up requirements of subsequent production and processing steps.
