The support includes a first upright plate and a second upright plate, i.e., the first upright plate and the second upright plate are arranged facing each other among a plurality of upright plates. Relative to the lifting platform, the picking component at the first transport position is located on the same side as the first upright plate, and the picking component at the second transport position is located on the same side as the second upright plate.
[0007] In one embodiment, the material transfer device further includes a lifting drive, the lifting platform includes a first connecting part and a second connecting part, the first connecting part and the second connecting part are facing each other and spaced apart, the first connecting part is slidably engaged with the first upright plate, the second connecting part is slidably engaged with the second upright plate, and the output part of the lifting drive extends between the first connecting part and the second connecting part and is simultaneously connected to the first connecting part and the second connecting part.

[0009] In one embodiment, the material transfer device further includes a rotating component, which includes a rotary driver and a transmission structure. The transmission structure is located on the end face of the lifting platform and is connected to the pickup component. The rotary driver is located in the side peripheral area of the lifting platform and is connected to the transmission structure. The rotary driver drives the transmission structure to rotate the pickup component.
[0010] In one embodiment, the pickup component includes a first driver and a second driver, the connecting frame is connected to the lifting platform, the first clamping structure and the second clamping structure are movably disposed on the connecting frame, the first driver is disposed on the connecting frame and connected to the first clamping structure to drive the first clamping structure to move closer to and away from the second clamping structure, and the second driver is disposed on the connecting frame and connected to the second clamping structure to drive the second clamping structure to move closer to and away from the first clamping structure.
[0011] In one embodiment, the picking component further includes a limiting member located between the first clamping structure and the second clamping structure in the clamping direction of the first clamping structure and the second clamping structure; the first clamping structure includes a first plate and a first abutting member, the first plate is slidably engaged with the connecting frame, the first abutting member is adjustablely disposed on the first plate along the clamping direction, and the first clamping structure moves toward the first clamping structure to a position where the first abutting member abuts against the limiting member; and / or, the second clamping structure includes a second plate and a second abutting member, the second plate is slidably engaged with the connecting frame, the second abutting member is adjustablely disposed on the second plate along the clamping direction, and the second clamping structure moves toward the first clamping structure to a position where the second abutting member abuts against the limiting member.

[0015] In the aforementioned material transfer device, the first and second clamping structures of the pickup component cooperate to clamp the workpiece. The pickup component can rise and fall with the lifting platform to remove the workpiece from or place it into a fixture or similar structure. Furthermore, the pickup component can rotate relative to the lifting platform to align with different workstations, thereby transferring the workpiece. It is readily understood that at least two positions during the rotation of the pickup component relative to the lifting platform are such that at least a portion of the pickup component's projection along the reference axis onto the lifting platform lies outside the lifting platform. That is, at least two positions are where the pickup component extends outward relative to the lifting platform.

Furthermore, the support and lifting platform occupy less space, enabling the material transfer device to be used in confined spaces.
[0016] Furthermore, the material transfer device mainly relies on the rotation of the picking component to move the workpiece to be aligned with different workstations to achieve workpiece transfer. Therefore, the material transfer device provided in this application does not require structures such as tracks to support the picking component, and occupies less space compared to devices such as conveyor belts and gantry-type robots, making it suitable for use in confined spaces.

[0024] 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.

[0028] See Figure 1 , Figure 1A schematic diagram of the modules of a production equipment provided in an embodiment of this application is shown. An embodiment of this application provides a production equipment 10, which includes a material transfer device 11 capable of picking up workpieces and driving them to switch workstations. Further, the production equipment 10 also includes a first processing device 12 and a second processing device 13. The material transfer device 11 is disposed between the first processing device 12 and the second processing device 13, and is used to transport workpieces from the first processing device 12 to the second processing device 13.
[0029] Please see Figure 2 and Figure 3 The material transfer device 11 provided in one embodiment of this application includes a support 100, a lifting platform 200, and a pickup component 300. Both the lifting platform 200 and the pickup component 300 are mounted on the support 100, and the pickup component 300 is used to pick up workpieces. The lifting platform 200 is movably mounted on the support 100 along a reference direction S. The pickup component 300 is mounted on the lifting platform 200 and can rotate relative to the lifting platform 200 around a reference axis O for alignment with different workstations. Figure 1 For example, the pickup assembly 300 can rotate about the reference axis O from a position aligned with the workstation at the first processing device 12 to a position aligned with the workstation at the second processing device 13. During at least two positions of the pickup assembly 300 relative to the lifting platform 200, at least a portion of the area of the pickup assembly 300's orthographic projection along the reference axis O onto the lifting platform 200 is located outside the lifting platform 200. These at least two positions of the pickup assembly 300 can be positions corresponding to picking up or placing a workpiece. The pickup assembly 300 includes a connecting frame 310, a first clamping structure 320, and a second clamping structure 330. At least one of the first clamping structure 320 and the second clamping structure 330 is movably disposed on the connecting frame 310 to move closer to and further away from the other for clamping the workpiece.
[0030] In the aforementioned material transfer device 11, the first clamping structure 320 and the second clamping structure 330 of the pickup assembly 300 cooperate to clamp the workpiece. The pickup assembly 300 can rise and fall with the lifting platform 200 to remove the workpiece from a fixture or other structure that carries the workpiece, or to place the workpiece into the fixture or other structure. Furthermore, the pickup assembly 300 can also rotate relative to the lifting platform 200 to rotate to a position aligned with different workstations, thereby transferring the workpiece. It is easy to understand that at least two positions during the rotation of the pickup assembly 300 relative to the lifting platform 200 are such that at least a portion of the area of the pickup assembly 300 projected onto the lifting platform 200 along the reference axis O is located outside the lifting platform 200. That is, at least two positions are such that the pickup assembly 300 extends outward relative to the lifting platform 200. This facilitates alignment of the pickup assembly 300 with each workstation, thereby ensuring stable transfer of the workpiece. On the other hand, the support 100 and the lifting platform 200 can occupy less space, enabling the material transfer device 11 to be used in confined spaces.
[0031] Furthermore, the material transfer device 11 mainly relies on the rotation of the picking component 300 to drive the workpiece to be aligned with different workstations to achieve workpiece transfer. Therefore, the material transfer device 11 provided in this application does not require a track or other structure to support the picking component 300, and occupies less space compared to devices such as conveyor belts and gantry-type robots, making it suitable for use in confined spaces.
[0032] Please see Figure 3 In one embodiment, at any position of the pickup component 300 during its rotation relative to the lifting platform 200, at least a portion of the area of the pickup component 300 projected onto the lifting platform 200 along the reference axis O is located outside the lifting platform 200.
[0033] Please see Figure 3 In one embodiment, the reference axis O is arranged parallel to the reference direction S.
[0034] Please continue reading. Figure 3 In one embodiment, the support 100 includes a plurality of upright plates 110, at least two of which are arranged facing each other, and the lifting platform 200 is slidably engaged with the at least two opposing upright plates 110. In other words, both opposing upright plates 110 can provide support for the lifting platform 200 to reduce the shaking and swaying of the extended pickup component 300 during movement and improve the stability of the transferred workpiece.
[0035] In some embodiments, the number of upright plates 110 can be four, and the four upright plates 110 are arranged sequentially in the circumferential direction around the reference axis O to further improve the stability of the rotational movement of the pickup assembly 300.
[0036] Please continue reading. Figure 3In one embodiment, the support 100 includes a base 120. The support 100 includes a first upright plate 111 and a second upright plate 112, i.e., among the plurality of upright plates 110, there are a first upright plate 111 and a second upright plate 112. The first upright plate 111 and the second upright plate 112 are both disposed on the base 120, and the first upright plate 111 and the second upright plate 112 are arranged facing each other and are slidably engaged with the lifting platform 200. The pickup component 300 can rotate relative to the lifting platform 200 to a first transport position and a second transport position. The pickup component 300 in the first transport position is aligned with the first processing device 12, and the pickup component 300 in the second transport position is aligned with the second processing device 13. Relative to the lifting platform 200, the pickup component 300 in the first transport position is located on the same side as the first upright plate 111. Relative to the lifting platform 200, the pickup component 300 in the second transport position is located on the same side as the second upright plate 112. The pickup components 300 at the two transport positions are aligned with the two processing devices, so the pickup components 300 and the lifting platform 200 usually also have lifting and lowering movements to pick up or place workpieces. Therefore, the positions of the two vertical plates 110 (i.e., the first vertical plate 111 and the second vertical plate 112) are aligned with the two transport positions of the pickup components 300, which can effectively provide support for the lifting platform 200 and the pickup components 300 and improve their movement stability.
[0037] Please see Figure 3 In one embodiment, a first upright plate 111 and a second upright plate 112 are spaced apart to form an accommodating space 101. A lifting platform 200 movably passes through the accommodating space 101 to slide with the first upright plate 111 and the second upright plate 112. The support 100 also includes a first guide rail 130 and a second guide rail 140. The first guide rail 130 is disposed on the first upright plate 111, and the second guide rail 140 is disposed on the second upright plate 112. Both the first guide rail 130 and the second guide rail 140 extend along a reference direction S. The lifting platform 200 slides with both the first guide rail 130 and the second guide rail 140.
[0038] Please continue reading. Figure 3 In one embodiment, the material transfer device 11 further includes a lifting driver 400, which is disposed within the accommodating space 101 to improve space utilization and make the material transfer device 11 easily applicable in confined spaces. The lifting platform 200 includes a first connecting portion 210 and a second connecting portion 220, which face each other and are spaced apart. The first connecting portion 210 is slidably engaged with a first upright plate 111, and the second connecting portion 220 is slidably engaged with a second upright plate 112. The output portion 410 of the lifting driver 400 extends between the first connecting portion 210 and the second connecting portion 220 and connects to both portions simultaneously, so as to drive the first connecting portion 210 and the second connecting portion 220 to move synchronously, reducing the probability of skewness or jamming.
[0039] In one embodiment, the lifting platform 200 further includes a connecting plate 230 and a support platform 240. The connecting plate 230 is connected between the first connecting portion 210 and the second connecting portion 220. The lifting drive 400 is simultaneously connected to the first connecting portion 210 and the second connecting portion 220 via the connecting plate 230. The support platform 240 is located on the same side of the first connecting portion 210 and the second connecting portion 220, and is connected to both the first connecting portion 210 and the second connecting portion 220. The pickup assembly 300 is disposed on the support platform 240.
[0040] Please see Figure 2 and Figure 3 In one embodiment, the material transfer device 11 further includes a rotating assembly 500, which is disposed on the lifting platform 200 and connected to the picking assembly 300 to drive the picking assembly 300 to rotate about the reference axis O. Further, the rotating assembly 500 is disposed on the support platform 240.
[0041] Please see Figure 2 and Figure 3 In one embodiment, the rotating assembly 500 includes a rotary driver 510 and a transmission structure 520. The transmission structure 520 is located on the end face of the lifting platform 200, that is, on the upper end face of the support platform 240, and is connected to the pickup assembly 300. The rotary driver 510 is located in the lateral region of the lifting platform 200 and is connected to the transmission structure 520. The rotary driver 510 drives the transmission structure 520 to rotate the pickup assembly 300. Since the rotary driver 510 is located in the lateral region of the lifting platform 200, it is not directly located between the lifting platform 200 and the pickup assembly 300, thereby relatively reducing the dimensions of the lifting platform 200 and the pickup assembly 300 in the direction of the reference axis O and improving structural stability. It is understood that conventional rotary drivers 510 (e.g., motors) are usually constructed with a long axial dimension, which may result in a large radial runout when the pickup assembly 300 rotates. In other words, by configuring the transmission structure 520 to replace the rotary drive 510 between the lifting platform 200 and the pickup assembly 300, this application can relatively reduce the axial dimension, reduce the radial runout of the pickup assembly 300 during rotation, and improve the positional stability of the pickup assembly 300. Furthermore, the transmission structure 520 can be configured as a hollow rotary platform.
[0042] Please see Figure 2 and Figure 3In one embodiment, the material transfer device 11 further includes a plurality of buffers 600, which are disposed on the support 100. The lifting platform 200 also includes abutment blocks 250, and the number of abutment blocks 250 can be two. The two abutment blocks 250 are respectively connected to the first connecting part 210 and the second connecting part 220. In the reference direction S, at least two buffers 600 are respectively located on opposite sides of the abutment blocks 250. The lifting platform 200 can move to the position where the abutment blocks 250 abut against the buffers 600, and the buffers 600 can buffer the lifting movement of the lifting platform 200. Further, the first upright plate 111 may be provided with two buffers 600 to correspond to the abutment blocks 250 connected to the first upright plate 111.
[0043] Please see Figure 4 In one embodiment, as described above, the pickup component 300 is configured as a gripper for gripping and picking up workpieces, and the connecting frame 310 is connected to the lifting platform 200. The pickup component 300 also includes a first driver 340 and a second driver 350. Both the first clamping structure 320 and the second clamping structure 330 are movably disposed on the connecting frame 310. The first driver 340 is disposed on the connecting frame 310 and connected to the first clamping structure 320 to drive the first clamping structure 320 towards and away from the second clamping structure 330. The second driver 350 is disposed on the connecting frame 310 and connected to the second clamping structure 330 to drive the second clamping structure 330 towards and away from the first clamping structure 320. In short, the first clamping structure 320 and the second clamping structure 330 are independently and movably disposed on the connecting frame 310 to facilitate workpiece gripping.
[0044] Please continue reading. Figure 4 In one embodiment, the pickup assembly 300 further includes a limiting member 360. The limiting member 360 is located between the first clamping structure 320 and the second clamping structure 330 in the clamping direction K of the first clamping structure 320 and the second clamping structure 330. The limiting member 360 is used to abut against the first clamping structure 320 and / or the second clamping structure 330 to restrict the movement of the first clamping structure 320 and / or the second clamping structure 330. It is understood that since the limiting member 360 is located between the first clamping structure 320 and the second clamping structure 330, the limiting member 360 is mainly used to limit the movement of the two structures closer to each other, reducing the probability of the pickup assembly 300 over-clamping and damaging the workpiece.
[0045] Please see Figure 4In one embodiment, the first clamping structure 320 includes a first plate 321 and a first abutting member 322. The first plate 321 is slidably engaged with the connecting frame 310, and the first abutting member 322 is adjustablely positioned on the first plate 321 along the clamping direction K. The first clamping structure 320 can move towards itself until the first abutting member 322 abuts against the limiting member 360. That is, the limiting member 360 limits the position of the first clamping structure 320 by abutting against the first abutting member 322. Since the first abutting member 322 is adjustablely positioned on the first plate 321 along the clamping direction K, adjusting the position of the first abutting member 322 can adjust the overall position of the first clamping structure 320 when it abuts against the limiting member 360, facilitating adaptation to workpieces of different sizes. For example, the closer the first abutment 322 is to the limiting member 360 on the first plate 321, the smaller the maximum displacement of the first clamping structure 320 from a position away from the second clamping structure 330 to a position closer to the second clamping structure 330. In this case, the pickup assembly 300 can be used to clamp relatively large workpieces.
[0046] In one embodiment, the first abutment 322 is configured as a bolt, and the first abutment 322 is threadedly engaged with the first plate 321. Its position in the clamping direction K can be adjusted by screwing on the first abutment 322.
[0047] Similarly, in one embodiment, the second clamping structure 330 includes a second plate 331 and a second abutment 332. The second plate 331 is slidably engaged with the connecting frame 310, and the second abutment 332 is adjustablely positioned on the second plate 331 along the clamping direction K. The second clamping structure 330 moves toward the first clamping structure 320 until it reaches a position where the second abutment 332 abuts against the limiting member 360. That is, the limiting member 360 limits the position of the second clamping structure 330 by abutting against the second abutment 332. Since the second abutment 332 is adjustablely positioned on the second plate 331 along the clamping direction K, the overall position of the second clamping structure 330 when abutting against the limiting member 360 can be adjusted by adjusting the position of the second abutment 332, making it easier to adapt to workpieces of different sizes. For example, the closer the second abutment 332 is to the limiting member 360 on the second plate 331, the smaller the maximum displacement of the second clamping structure 330 from a position away from the first clamping structure 320 to a position closer to the first clamping structure 320. In this case, the pickup assembly 300 can be used to clamp relatively large workpieces.
[0048] Please continue reading. Figure 4In one embodiment, the first clamping structure 320 further includes a first clamping member 323, which is disposed on the first plate 321 and is the portion of the first clamping structure 320 used to contact the workpiece. The second clamping structure 330 further includes a second clamping member 333, which is disposed on the second plate 331 and is the portion of the second clamping structure 330 used to contact the workpiece. The first clamping member 323 includes a first limiting body 324, which is disposed on the side of the first clamping member 323 facing the second clamping member 333. The second clamping member 333 includes a second limiting body 334, which is disposed on the side of the second clamping member 333 facing the first clamping member 323. The first limiting body 324 and the second limiting body 334 are used for limiting and engaging with the workpiece. Therefore, the pickup assembly 300 can not only fix the workpiece by the clamping force of the first clamping structure 320 and the second clamping structure 330, but also utilize the limiting effect of the first limiting body 324 and the second limiting body 334 when they are engaged with the workpiece to allow the workpiece to change position as the pickup assembly 300 moves. In short, configuring the first limiting body 324 and the second limiting body 334 can improve the stability of the pickup assembly 300 in picking up the workpiece.
[0049] Furthermore, the first limiting body 324 and the second limiting body 334 can be inserted and limited in conjunction with the workpiece. Alternatively, the first limiting body 324 and the second limiting body 334 can simply support the bottom of the workpiece to improve the stability of the pick-up assembly 300 in picking up the workpiece.
[0050] In one embodiment, the pickup assembly 300 further includes a slide rail (not shown, the same below), which is disposed on the connecting frame 310 and extends along the clamping direction K. The first clamping structure 320 and the second clamping structure 330 are both slidably engaged with the slide rail.
