[0024] Reference Figure 1 The positioning fixture for automatically flipping products according to an embodiment of this application includes: a first positioning component 100, a second positioning component 200, and a rotating component 300.

[0025] The first positioning component 100 includes a first support plate 110 and a first positioning structure. The first support plate 110 is used to place the product 400 in a first posture, and the first positioning structure is used to position the product 400 on the first support plate 110. The second positioning component 200 includes a second support plate 210 and a second positioning structure. The second support plate 210 is used to place the product 400 in a second posture, and the second positioning structure is used to position the product 400 on the second support plate 210. The rotating assembly 300 includes a first clamping plate 310, a second clamping plate 320, a clamping driver 330, a rotating driver 340, and a rotating part 350. The first clamping plate 310, the second clamping plate 320, and the clamping driver 330 are disposed on the rotating part 350. The clamping driver 330 drives and connects to at least one of the first clamping plate 310 and the second clamping plate 320 to drive the first clamping plate 310 and the second clamping plate 320 to move closer to or further away from each other. The rotating part 350 is located between the first support plate 110 and the second support plate 210. The rotating driver 340 drives and connects to the rotating part 350 to drive the rotating part 350 to rotate, thereby rotating the first clamping plate 310 and the second clamping plate 320 to opposite sides of the first support plate 110 or to opposite sides of the second support plate 210.

[0026] First, it should be noted that in this embodiment, reference is made to... Figure 3 When product 400 is in the first position, that is, the front side 410 of product 400 is facing upwards, it is convenient to process the front side 410 of product 400, referring to... Figure 5When product 400 is in the second posture, that is, the reverse side 420 of product 400 is facing upwards, it is convenient to process the reverse side 420 of product 400. Of course, it should also be noted that in some other embodiments, the first posture and the second posture of product 400 can also be any posture of product 400 after being flipped, for example, the side of product 400 is facing upwards, which is convenient to process the side of product 400. This is not limited here and can be determined according to the actual processing requirements of product 400.

[0027] Understandably, referring to Figure 3 The product 400 is placed on the first support plate 110 in a first orientation, with its front surface 410 facing upwards. This facilitates processing of the front surface 410 of the product 400, and the first positioning structure positions the product 400 on the first support plate 110, improving the processing accuracy of the product 400. The clamping driver 330 drives the first clamping plate 310 and the second clamping plate 320 to move closer together, clamping the product 400 on the first support plate 110, thus further improving the positioning accuracy of the product 400 in conjunction with the first positioning structure. (Refer to...) Figure 4 After the front side 410 of product 400 is processed, the rotary driver 340 drives the rotating part 350 to rotate. The rotating part 350 drives the first clamping plate 310 and the second clamping plate 320 to rotate, and causes the product 400 held by the first clamping plate 310 and the second clamping plate 320 to flip over. Figure 5 Product 400 flips to a second orientation and falls onto the second support plate 210. At this point, the reverse side 420 of product 400 faces upward, facilitating processing of the reverse side 420. The second positioning structure also positions product 400 on the second support plate 210, improving processing accuracy. Simultaneously, the next product 400 can be placed on the first support plate 110 in its first orientation, allowing for simultaneous processing of both the front side 410 and the reverse side 420 of product 400 on the first support plate 110, thus increasing production efficiency.

[0028] In summary, the first clamping plate 310 and the second clamping plate 320, in conjunction with the first positioning structure, position the product 400 on the first support plate 110 to facilitate processing of the front side 410 of the product 400. After processing of the front side 410 of the product 400, driven by the rotary driver 340 and the rotating part 350, the first clamping plate 310 and the second clamping plate 320 can rotate the product 400 onto the second support plate 210. The second positioning structure then positions the product 400 on the second support plate 210 to facilitate processing of the reverse side 420 of the product 400. This achieves automatic rotation of the product 400, improving production efficiency. Furthermore, after the previous product 400 rotates onto the second support plate 210, the next product 400 can be placed on the first support plate 110, and the products 400 on both the first support plate 110 and the second support plate 210 can be processed simultaneously, further improving production efficiency.

[0029] Specifically, the rotary driver 340 is a motor, the rotating part 350 is a rotating shaft, the second clamping plate 320 is fixed on the outside of the rotating shaft, the clamping driver 330 is a cylinder, the clamping driver 330 is fixed on the outside of the rotating shaft, and the clamping driver 330 drives the first clamping plate 310 to move closer to or away from the second clamping plate 320. When the first clamping plate 310 moves closer to the second clamping plate 320, the first clamping plate 310 and the second clamping plate 320 can abut against the opposite sides of the product 400 to position the product 400. When the first clamping plate 310 moves away from the second clamping plate 320, the positioning of the product 400 can be canceled.

[0030] Reference Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, the first positioning structure includes a first positioning plate 120, a first limiting plate 130, and a first driver 140. The first positioning plate 120 and the first limiting plate 130 are located on opposite sides of the first support plate 110. The first driver 140 drives at least one of the first positioning plate 120 and the first limiting plate 130 to move closer to or further away from each other.

[0031] Understandably, the first driver 140 drives the first positioning plate 120 and the first limiting plate 130 to move closer to each other, and the first positioning plate 120 and the first limiting plate 130 can abut against the opposite sides of the product 400 placed on the first support plate 110 to position the product 400.

[0032] Specifically, the first driver 140 is a cylinder, the first positioning plate 120 is movably set, and the first limiting plate 130 is fixedly set relative to the first support plate 110. The first driver 140 drives the first positioning plate 120 to move the first positioning plate 120 closer to or away from the first limiting plate 130. When the first positioning plate 120 moves closer to the first limiting plate 130, the first positioning plate 120 and the first limiting plate 130 can abut against the opposite sides of the product 400 to position the product 400. When the first positioning plate 120 moves away from the first limiting plate 130, the positioning of the product 400 can be canceled.

[0033] Reference Figure 1 According to some embodiments of this application, the first positioning plate 120 and the first limiting plate 130 are located on both sides of the first support plate 110 in a first direction, and the first clamping plate 310 and the second clamping plate 320 can rotate to both sides of the first support plate 110 in a second direction, wherein the first direction and the second direction intersect.

[0034] Understandably, under the driving action of the first driver 140, the first positioning plate 120 and the first limiting plate 130 position the two sides of the product 400 in the first direction. Under the driving action of the clamping driver 330, the first clamping plate 310 and the second clamping plate 320 position the two sides of the product 400 in the second direction. Thus, by positioning the two sides of the product 400 in the first direction and the two sides in the second direction respectively, the positioning effect of the product 400 can be improved.

[0035] Specifically, the first direction and the second direction are perpendicular.

[0036] Reference Figure 1 and Figure 3 According to some embodiments of this application, the first positioning component 100 further includes an elastic block 150, which is located on the same side of the first support plate 110 as the first limiting plate 130. When the first positioning plate 120 and the first limiting plate 130 clamp the product 400, the elastic block 150 is used to abut against the product 400 and give the product 400 an elastic force away from the first limiting plate 130.

[0037] It is understandable that the side of the elastic block 150 that abuts against the product 400 is closer to the first support plate 110 than the side of the first limiting plate 130 that abuts against the product 400. That is, during the process of the first driver 140 driving the first positioning plate 120 to approach the first limiting plate 130, the first positioning plate 120 abuts against one side of the product 400 in the first direction and pushes the product 400 toward the first limiting plate 130 and the elastic block 150. The other side of the product 400 in the first direction will abut against the elastic block 150 first. Under the continuous drive of the first driver 140, the product 400 pushes the elastic block 150 to compress, and the other side of the product 400 in the first direction will abut against the first limiting plate 130. The first positioning plate 120 and the first limiting plate 130 position the two sides of the product 400 in the first direction. Thus, the elastic block 150 can play a buffering role during the process of the first positioning plate 120 and the first limiting plate 130 positioning the product 400. When it is necessary to cancel the positioning of product 400 in the first direction, the first driver 140 drives the first positioning plate 120 away from product 400, the elastic block 150 rebounds, and the elastic block 150 pushes product 400 away from the first limiting plate 130. Thus, when the first clamping plate 310 and the second clamping plate 320 drive product 400 to flip, the risk of product 400 scratching the first limiting plate 130 is reduced, ensuring the appearance yield of product 400.

[0038] Reference Figure 1 According to some embodiments of this application, the elastic block 150 is disposed on the rotating part 350.

[0039] Understandably, the elastic block 150 is disposed on the rotating part 350 and can rotate with the rotating part 350. During the rotation of the rotating part 350, the elastic block 150 remains against one side of the product 400 in the first direction, thereby reducing the risk of the product 400 scraping against the elastic block 150 during the rotation. Furthermore, during the rotation of the product 400, the elastic block 150 is located below the product 400, and the elastic block 150 can limit and support one side of the product 400, making it less likely for the product 400 to fall between the first clamping plate 310 and the second clamping plate 320 during the rotation.

[0040] Reference Figure 1 and Figure 3 According to some embodiments of this application, the first positioning component 100 further includes a first prepositioning plate 160 and a second prepositioning plate 170, which are located on both sides of the first support plate 110 in a second direction.

[0041] In some embodiments, the first clamping plate 310 can cooperate with the second prepositioning plate 170 to clamp the product 400. The second clamping plate 320 is made of plastic material. When the first clamping plate 310 and the second prepositioning plate 170 clamp the product 400, they can provide the product 400 with an elastic force that moves it away from the second prepositioning plate 170.

[0042] Understandably, before the product 400 is placed on the first support plate 110, the first clamping plate 310 and the second clamping plate 320 have already been flipped to their respective sides on the first support plate 110. The side of the second clamping plate 320 that abuts against the product 400 is closer to the first support plate 110 than the side of the second pre-positioning plate 170 that abuts against the product 400. Furthermore, before the clamping driver 330 drives the first clamping plate 310, the side of the first pre-positioning plate 160 that is closer to the first support plate 110 is closer to the first support plate 110 than the side of the first clamping plate 310 that abuts against the product 400. That is, after the product 400 is placed on the first support plate 110, both sides of the product 400 in the second direction are located between the first pre-positioning plate 160 and the second clamping plate 320, which provide initial positioning for the product 400. Subsequently, under the driving action of the clamping driver 330, the first clamping plate 310 abuts against one side of the product 400 in the second direction. Under the continuous driving of the clamping driver 330, the product 400 pushes the second clamping plate 320 to compress, and the other side of the product 400 in the second direction abuts against the second pre-positioning plate 170. The first clamping plate 310 and the second pre-positioning plate 170 position the two sides of the product 400 in the second direction. Thus, the second clamping plate 320 can play a buffering role during the positioning of the product 400 by the first clamping plate 310 and the second pre-positioning plate 170. When it is necessary to cancel the positioning of the product 400 in the second direction, the clamping driver 330 drives the first clamping plate 310 away from the product 400, the second clamping plate 320 springs back, and the second clamping plate 320 pushes the product 400 away from the second pre-positioning plate 170. Thus, when the first clamping plate 310 and the second clamping plate 320 rotate the product 400, the risk of the product 400 scratching the second pre-positioning plate 170 is reduced, ensuring the appearance yield of the product 400.

[0043] In some other embodiments, the product 400 is placed on the first support plate 110. The product 400 is initially positioned by the first prepositioning plate 160 and the second prepositioning plate 170. Subsequently, the first clamping plate 310 and the second clamping plate 320 are flipped to the sides of the first support plate 110. Then, under the driving action of the clamping driver 330, the first clamping plate 310 and the second clamping plate 320 abut against the two sides of the product 400 in the second direction to position the two sides of the product 400 in the second direction.

[0044] Of course, it should also be understood that in some other embodiments, the first prepositioning plate 160 and the second prepositioning plate 170 may not be provided, and the product 400 on the first support plate 110 may be positioned on both sides in the second direction by relying solely on the first clamping plate 310 and the second clamping plate 320.

[0045] Reference Figure 1 , Figure 2 and Figure 5 According to some embodiments of this application, the second positioning structure includes a second positioning plate 220, a second limiting plate 230, and a second driver 240. The second support plate 210 is used to place the product 400 in a second posture. The second positioning plate 220 and the second limiting plate 230 are located on opposite sides of the second support plate 210. The second driver 240 drives at least one of the second positioning plate 220 and the second limiting plate 230 to move closer to or further away from each other.

[0046] Understandably, the second driver 240 drives the second positioning plate 220 and the second limiting plate 230 to move closer to each other, and the second positioning plate 220 and the second limiting plate 230 can abut against the opposite sides of the product 400 placed on the second support plate 210 to position the product 400.

[0047] Specifically, the second driver 240 is a cylinder, the second positioning plate 220 is movably set, and the second limiting plate 230 is fixedly set relative to the second support plate 210. The second driver 240 drives the second positioning plate 220 to move the second positioning plate 220 closer to or away from the second limiting plate 230. When the second positioning plate 220 moves closer to the second limiting plate 230, the second positioning plate 220 and the second limiting plate 230 can abut against the opposite sides of the product 400 to position the product 400. When the second positioning plate 220 moves away from the second limiting plate 230, the positioning of the product 400 can be canceled.

[0048] Reference Figure 1 and Figure 5 According to some embodiments of this application, the second positioning plate 220 and the second limiting plate 230 are located on both sides of the second support plate 210 in the first direction, and the first clamping plate 310 and the second clamping plate 320 can rotate to both sides of the second support plate 210 in the second direction, wherein the first direction and the second direction intersect.

[0049] Understandably, under the driving action of the second driver 240, the second positioning plate 220 and the second limiting plate 230 position the product 400 on both sides in the first direction.

[0050] Specifically, the second direction is perpendicular to the second direction.

[0051] Reference Figure 1 and Figure 5 According to some embodiments of this application, the second positioning component 200 further includes a third positioning structure, which includes a third positioning plate 250, a third limiting plate 260, and a third driver 270. The third positioning plate 250 and the third limiting plate 260 are located on both sides in the second direction. The third driver 270 drives at least one of the third positioning plate 250 and the third limiting plate 260 to move closer to or further away from each other.

[0052] Understandably, after product 400 flips onto the second support plate 210, the rotary actuator 340 drives the rotating part 350 to immediately return the first clamping plate 310 and the second clamping plate 320 to both sides of the first support plate 110. The third positioning structure then positions the product 400 on the second support plate 210 in the second direction. Specifically, the third actuator 270 drives the third positioning plate 250 and the third limiting plate 260 to move closer together, allowing them to abut against the product 400 on the second support plate 210 in the second direction, thus positioning the product 400 in the second direction. Therefore, the second and third positioning structures work together to position the product 400 on both sides in the first and second directions, improving the positioning effect. Furthermore, by adding a third positioning structure to the side of the second support plate 210, which replaces the first clamping plate 310 and the second clamping plate 320 in positioning the product 400, production efficiency can be further improved.

[0053] Specifically, the third actuator 270 is a cylinder, the third positioning plate 250 is movably set, and the third limiting plate 260 is fixedly set relative to the second support plate 210. The third actuator 270 drives the third positioning plate 250 to move the third positioning plate 250 closer to or away from the third limiting plate 260. When the third positioning plate 250 moves closer to the third limiting plate 260, the third positioning plate 250 and the third limiting plate 260 can abut against the opposite sides of the product 400 to position the product 400. When the third positioning plate 250 moves away from the third limiting plate 260, the positioning of the product 400 can be canceled.

[0054] In some other embodiments, the third positioning structure may be omitted, and the first clamping plate 310 and the second clamping plate 320, in conjunction with the second positioning structure, can position the sides of the product 400 in two directions. Specifically, after the product 400 is flipped onto the second support plate 210, under the driving action of the clamping driver 330, the first clamping plate 310 and the second clamping plate 320 position the sides of the product 400 in the second direction. Under the driving action of the second driver 240, the second positioning plate 220 and the second limiting plate 230 position the sides of the product 400 in the first direction. Reference Figure 1 According to some embodiments of this application, the first clamping plate 310 and the second clamping plate 320 are offset in a second direction.

[0055] It is understandable that the first clamping plate 310 and the second clamping plate 320 are offset in the second direction, that is, the projections of the first clamping plate 310 and the second clamping plate 320 on the vertical plane perpendicular to the second direction are offset. It should be understood that the first clamping plate 310 and the second clamping plate 320 need to be flipped to both sides of the second support plate 210 in the second direction, and the third positioning plate 250 and the third limiting plate 260 are also located on both sides of the second support plate 210 in the second direction. Therefore, the size of the first clamping plate 310, the second clamping plate 320, the third positioning plate 250 and the third limiting plate 260 cannot be made too large, and they need to be staggered to avoid interference. Thus, the first clamping plate 310 and the second clamping plate 320 are staggered in the second direction, and the third positioning plate 250 and the third limiting plate 260 are also staggered in the second direction, and the staggered position is opposite to that of the first clamping plate 310 and the second clamping plate 320 to avoid interference. Since the first clamping plate 310 and the second clamping plate 320 are staggered in the second direction, when the first clamping plate 310 and the second clamping plate 320 clamp the product 400, they can clamp the product 400 at the staggered position in the second direction, improve the clamping stability of the product 400, and prevent the product 400 from tilting to one side during the flipping process.

[0056] In some other embodiments, the first clamping plate 310 and the second clamping plate 320 may also be arranged opposite to each other, that is, the projections of the first clamping plate 310 and the second clamping plate 320 on a vertical plane perpendicular to the second direction at least partially overlap, while the third positioning plate 250 and the third limiting plate 260 are also arranged opposite to each other.

[0057] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
