Description

Technical Field

[0001] This invention relates to the field of electronic component assembly technology, and in particular to a feeding device. Background Technology

[0002] With the development of display technology in the electronics industry, the internal structure of screens is constantly becoming more precise. Consequently, the requirements for assembly precision in screens are also increasing. Current technology typically uses enclosure structures to enclose the delicate structures on the screen to ensure the assembly of internal components. However, the assembly of these enclosures is currently still done manually, which is inefficient and results in low assembly precision. Summary of the Invention

[0003] Therefore, it is necessary to provide a feeding device to address the assembly problem of the enclosure structure.

[0004] A straightening device is used to straighten the shape and position of a workpiece, the straightening device comprising:

[0005] Fixed fixture;

[0006] A straightening structure is provided for moving a workpiece from a first position to a second position. The straightening structure includes a first straightening component and a second straightening component. The first straightening component contacts a first sidewall of the workpiece to drive the workpiece to move along a first direction until the first sidewall contacts the fixed fixture. The second straightening component contacts a second sidewall of the workpiece to drive the workpiece to move along a second direction until the second sidewall contacts the fixed fixture. The first direction and the second direction are set at an angle. The first straightening component is used to press against the first sidewall when the workpiece is in the second position to keep the first sidewall in contact with the fixed fixture. The second straightening component is used to press against the second sidewall when the workpiece is in the second position to keep the second sidewall in contact with the fixed fixture.

[0007] In one embodiment, the fixing fixture surrounds a correction area, the orthographic projection of the first correction component in the plane of the fixing fixture is located within the correction area, the workpiece in the first position is located within the correction area, and when the workpiece is in the first position, the first side stop is located between the fixing fixture and the first correction component.

[0008] In one embodiment, the first correction component includes a first drive member and a first push member, wherein the first drive member is connected to the first push member for driving the first push member to move along the first direction.

[0009] In one embodiment, the fixing fixture has a receiving groove for accommodating the workpiece, and a through hole is formed on the bottom wall of the receiving groove. The first straightening component and the second straightening component pass through the through hole, and the first direction and the second direction point to the side wall of the receiving groove. The first side stop in the second position keeps in contact with the side wall of the receiving groove, and the second side stop in the second position keeps in contact with the side wall of the receiving groove.

[0010] In one embodiment, the through hole has a plurality of mating grooves on its wall, the plurality of mating grooves being spaced apart along the extension direction of the sidewall of the receiving groove, the first pusher having a plurality of spaced contact portions, the plurality of contact portions being respectively slidably engaged with the groove wall of the mating groove, and a portion of the structure of the plurality of contact portions being located outside the mating groove to contact and press against the workpiece.

[0011] In one embodiment, at least two positioning blocks are provided on the bottom wall of the receiving groove, and the workpiece in the first position can contact at least two of the positioning blocks.

[0012] In one embodiment, the correction structure further includes a third correction component for pressing against the workpiece when the workpiece is in the second position. The third correction component is capable of pushing against the workpiece in a third direction so that each edge of the workpiece remains in contact with the fixing fixture.

[0013] In one embodiment, the fixture has a plurality of adsorption holes for communicating with a vacuum generator, and the workpiece in the second position can cover the plurality of adsorption holes.

[0014] A feeding device, the feeding device comprising:

[0015] The correction device as described in any of the above embodiments;

[0016] A flipping device, comprising a rotating shaft, is connected to the corrective device for driving the corrective device to rotate a preset angle around the rotating shaft as the axis of rotation.

[0017] In one embodiment, the flipping device further includes a support member and a drive structure disposed on the support member. The drive structure is connected to the rotating shaft for driving the rotating shaft to rotate by the preset angle. The support member is provided with an optocoupler. When the optocoupler is triggered, it can control the drive structure to stop moving. The rotating shaft is provided with a baffle plate, which is used to trigger the optocoupler when the rotating shaft rotates through the preset angle.

[0018] In one embodiment, the correction device further includes a support member for supporting the fixation fixture and the correction structure, and the flipping device further includes a limiting structure for abutting the support member when the rotating shaft rotates through the preset angle, and the limiting structure for keeping the correction device and the flipping device relatively fixed.

[0019] In the aforementioned straightening device, the first direction and the second direction are not parallel. Therefore, the straightening structure combined with the fixing fixture can ensure that the workpiece has a definite preset position, namely the second position, within the plane containing the first and second directions. In this way, the workpiece can be positioned by the first and second straightening components to ensure the accuracy of workpiece assembly.

[0020] Furthermore, when in the second position, the first straightening component can press against the first side stop to bring it into contact with the fixing fixture. That is, when the workpiece is in the second position, the first straightening component and the fixing fixture can cooperate to clamp the workpiece. This allows the shape of the workpiece to be corrected, giving it a preset shape. The second straightening component can also be used to correct the shape of the workpiece in a similar manner to the first straightening component, and therefore will not be described further.

[0038] Figure 1 shows an isometric view of the feeding device according to an embodiment of the present invention; Figure 2 This shows one type of workpiece that the feeding equipment is designed for.

[0039] See Figure 1 and Figure 2An embodiment of the present invention provides a feeding device 10, including a straightening device 100 and a flipping device 200. The flipping device 200 includes a rotating shaft 210, and the flipping device 200 is connected to the straightening device 100 for driving the straightening device 100 to rotate by a preset angle about the rotating shaft 210 as the rotation axis. Figure 2 It is understandable that, as the internal structure of screens continues to become more sophisticated, technologies such as... Figure 2 The frame-like structure or "U"-shaped structure shown encloses the components inside the screen to ensure the accuracy of the installation of the corresponding components inside the screen.

[0040] In the aforementioned feeding device 10, the workpiece 20 is placed on the straightening device 100. Thus, after the straightening device 100 is driven to rotate through a preset angle by the flipping device 200, the workpiece 20 can be fed onto the screen. Therefore, by accurately controlling the preset angle through the feeding device 10, the positional accuracy of the workpiece 20 relative to the screen can be ensured, that is, the assembly accuracy of the workpiece 20 can be guaranteed.

[0041] Furthermore, in one embodiment, the correction device 100 is used to correct the shape and position of the workpiece 20. It should be understood that, to ensure the precision of the screen, the cross-sectional dimensions of each edge of the workpiece 20 need to be minimized; that is, each edge of the workpiece 20 is typically elongated. This will cause the edges of the workpiece 20 to easily deform during manufacturing or handling, and the deformed workpiece 20 often cannot maintain its preset shape, making it difficult to assemble the workpiece 20 into a preset position for stable contact with the screen. In this embodiment, the correction device 100 can correct the shape of the workpiece 20, thus ensuring that the workpiece 20 maintains a preset shape and fits snugly against the screen. Furthermore, the correction device 100 can also correct the position of the workpiece 20. This further ensures the positional accuracy of the workpiece 20 relative to the screen, guaranteeing that the workpiece 20 can be mounted on the preset position on the screen under the flipping action of the flipping device 200.

[0042] Please refer to 3 and Figure 4 In one embodiment, the straightening device 100 includes a fixing fixture 1100 and a straightening structure 1200. The straightening structure 1200 is used to move the workpiece 20 from a first position to a second position. It is understood that the second position refers to a predetermined position, that is, when the workpiece 20 is in the second position, the flipping device 200 drives the straightening device 100 to flip so that the workpiece 20 is mounted on a preset position on the screen. Conversely, the first position is the position of the workpiece 20 before the straightening device 100 straightens the workpiece 20, that is, the position when the workpiece 20 is loaded onto the straightening device 100.

[0043] Combination Figure 2The correction structure 1200 includes a first correction component 1210 and a second correction component 1220. The first correction component 1210 contacts the first side stop 21 of the workpiece 20 to drive the workpiece 20 to move along a first direction until the first side stop 21 of the workpiece 20 contacts the fixing fixture 1100. The second correction component 1220 contacts the second side stop 22 of the workpiece 20 to drive the workpiece 20 to move along a second direction until the second side stop 22 of the workpiece 20 contacts the fixing fixture 1100. (See the first direction section.) Figure 3 In the X-axis direction, see the second direction mentioned above. Figure 3 The Y-axis direction. The first direction and the second direction are set at an angle, that is, the first direction and the second direction are not parallel. It can be understood that the aforementioned first side stop 21 and second side stop 22 are the various side stops that make up the workpiece 20. In other words, the side of the first side stop 21 that contacts the first straightening component 1210, and the side of the first side stop 21 that contacts the fixing fixture 1100 can be different sides of the workpiece 20. The other side stops on the workpiece 20 are similar.

[0044] The first straightening component 1210 is used to press against the first side stop 21 when the workpiece 20 is in the second position so that the first side stop 21 is in contact with the fixing fixture 1100. The second straightening component 1220 is used to press against the second side stop 22 when the workpiece 20 is in the second position so that the second side stop 22 is in contact with the fixing fixture 1100.

[0045] The aforementioned correction device 100 has its first and second directions arranged at an angle, meaning they are not parallel. Therefore, the correction structure 1200, combined with the fixing fixture 1100, enables the workpiece 20 to have a predetermined position within the plane containing the first and second directions, namely the aforementioned second position. In other words, the workpiece 20 can be positioned using the first correction component 1210 and the second correction component 1220. Accurately positioning the workpiece 20 to the second position ensures the positional accuracy of the workpiece 20 relative to the screen when it is mounted on the screen.

[0046] Furthermore, when in the second position, the first straightening component 1210 can press against the first side stop 21 to make the first side stop 21 contact the fixing fixture 1100. That is, when the workpiece 20 is in the second position, the first straightening component 1210 and the fixing fixture 1100 can cooperate to clamp the workpiece 20. Thus, the shape of the workpiece 20 can be corrected to give the workpiece 20 a preset shape. The second straightening component 1220 can also be used to correct the shape of the workpiece 20 in a similar way, and the correction method is similar to that of the first straightening component 1210, so it will not be described again. It can be understood that the angle between the first direction and the second direction can be adaptively adjusted according to the angle between the first side stop 21 and the second side stop 22 of the workpiece 20 so that the straightening structure 1200 cooperates with the fixing fixture 1100 to correct the shape of the workpiece 20 to the expected shape.

[0047] It should be understood that in the above embodiments, the first direction and the second direction are located in the same two-dimensional plane, and the first direction and the second direction are not parallel. Thus, through the cooperation of the first correction component 1210 and the second correction component 1220 with the fixing fixture 1100, the workpiece 20 can be completely positioned in the two-dimensional plane. In other words, the workpiece 20 can be moved and held in the second position by the first correction component 1210 and the second correction component 1220.

[0048] For ease of explanation, the following description uses workpiece 20, which includes three side stops, as an example. Although to ensure the precision of the planar structure, the four side stops of workpiece 20 are typically designed to be elongated, which may cause the workpiece 20 to deform easily during manufacturing and transportation, this does not mean that the side stops of workpiece 20 cannot transmit force. That is, by having the first corrective component 1210 contact and push the first side stop 21, the workpiece 20 can be moved as a whole, and the second corrective component 1220 works similarly. In this way, workpiece 20 can be accurately moved to the second position.

[0049] Of course, combined Figure 3In the above embodiments, the straightening structure 1200 may further include two first straightening components 1210. Specifically, the workpiece 20 includes two opposing first side stops 21 and a second side stop 22. The two opposing first side stops 21 are respectively connected to both ends of the second side stop 22. The two first straightening components 1210 respectively contact the two first side stops 21. It can be understood that one of the first straightening components 1210 contacts one of the first side stops 21 and still drives the first side stop 21 to move along the first direction; the other first straightening component 1210 contacts the other first side stop 21 and drives the first side stop 21 to move in the opposite direction to the first direction until the first side stop 21 contacts the fixing fixture 1100. In this way, it can be further ensured that the workpiece 20 can be accurately moved to the second position. It should be understood that multiple first straightening components 1210 and / or multiple second straightening components 1220 may also be provided, and the driving direction of each straightening component driving the workpiece 20 may be adjusted to suit workpieces 20 with complex shapes, which will not be elaborated here.

[0050] Please see Figure 3 and Figure 4 In one embodiment, the fixing fixture 1100 surrounds a correction region 1120. The orthographic projection of the first correction component 1210 onto the plane of the fixing fixture 1100 lies within the correction region 1120. The workpiece 20 in a first position is located within the correction region 1120, and when the workpiece 20 is in the first position, the first side stop 21 is located between the fixing fixture 1100 and the first correction component 1210. The plane of the fixing fixture 1100 can be seen from... Figure 4 The XOY plane. It can be understood that part of the structure of the first straightening component 1210 is located within the straightening area 1120 to contact the workpiece 20.

[0051] For ease of explanation, let's take the first side stop 21 as an example: (Combined with...) Figure 2When workpiece 20 is in the first position, it is located within the correction area 1120. At this time, at least a portion of the first sidebar 21 is not in contact with the fixing fixture 1100, or all of the first sidebars 21 are in contact with the fixing fixture 1100, but stable contact between the first sidebar 21 and the fixing fixture 1100 cannot be guaranteed. By pushing the first sidebar 21 along the first direction with the first correction assembly 1210, the first sidebar 21 can be moved towards the side closer to the fixing fixture 1100, or at least has a tendency to move in the aforementioned direction. It is understood that since any sidebar of the fixing fixture 1100 is part of the correction area 1120, and workpiece 20 in the first position is located within the correction area 1120, when the first sidebar 21 moves along the first direction, any other sidebar on workpiece 20 connected to the first sidebar 21 will be subjected to a pulling force from the first sidebar 21, rather than a pushing force. Understandably, compared to driving the workpiece 20 as a whole by pushing, driving the workpiece 20 by pulling can avoid deformation of the workpiece 20 due to the driving force. In this way, it can be ensured that the workpiece 20 does not undergo unexpected deformation during the process of moving from the first position to the second position, and that the workpiece 20 can be maintained or corrected to the expected shape.

[0052] In the above embodiment, when the workpiece 20 is in the first position, the second side stop 22 is located between the fixing fixture 1100 and the second straightening component 1220. It can be understood that the workpiece 20 in the first position is located within the straightening area 1120, meaning that either side stop of the workpiece 20 is located within the straightening area 1120. Therefore, the second side stop 22 can also be moved to the second position without causing any expected external deformation.

[0053] Of course, the workpiece 20 can be set on the fixed fixture 1100 according to actual needs, and the position of the correction structure 1200 can be adjusted to ensure that the correction structure 1200 can be used to correct the shape and position of the workpiece 20.

[0054] Please see Figure 5 In one embodiment, the first correction assembly 1210 includes a first drive member 1211 and a first push member 1212. The first drive member 1211 is connected to the first push member 1212 for driving the first push member 1212 to move along a first direction. Specifically, the first push member 1212 is capable of contacting a first side stop 21 to drive the workpiece 20 to move along the first direction until the first side stop 21 contacts the fixing fixture 1100. The first push member 1212 is used to press against the first side stop 21 when the workpiece 20 is in a second position so that the first side stop 21 contacts the fixing fixture 1100.

[0055] In the above embodiment, the extending direction of the first pushing member 1212 can be the same as the extending direction of the first side stop 21, so as to ensure that the first pushing member 1212 can contact and press against each area on the first side stop 21. The extending directions of the first side stop 21 and the first pushing member 1212 are shown below. Figure 5 The Y-axis direction in the diagram. It is understood that this embodiment does not limit the first pushing member 1212 and the first side stop 21 to only extend along a straight line. When the first side stop 21 extends along a curve, the first pushing member 1212 can also extend along the aforementioned curve in a matching manner, which will not be elaborated further.

[0056] Please see Figure 6 and Figure 7 and combined Figure 4 In one embodiment, the fixing fixture 1100 has a receiving groove for accommodating the workpiece 20. A through hole 1111a is formed on the bottom wall 1111 of the receiving groove. It is understood that the through hole 1111a extends along the Z-axis direction and penetrates the bottom wall 1111 of the receiving groove.

[0057] The first correction component 1210 and the second correction component 1220 are disposed through the through hole 1111a. The first direction and the second direction point towards the side wall 1112 of the receiving groove. The first side stop 21 in the second position keeps in contact with the side wall 1112 of the receiving groove; the second side stop 22 in the second position keeps in contact with the side wall 1112 of the receiving groove.

[0058] Specifically, the bottom wall 1111 of the receiving groove is used to support the workpiece 20. The first straightening assembly 1210 and the second straightening assembly 1220 can move the workpiece 20 towards the side wall 1112 of the receiving groove until the workpiece 20 contacts the groove wall. Thus, through the combined action of the first straightening assembly 1210 and the second straightening assembly 1220 and the abutment of the groove wall, both the first sidewall 21 and the second sidewall 22 of the workpiece 20 maintain contact with the groove wall, thereby achieving shape correction of the workpiece 20.

[0059] Please see Figures 4 to 6 In one embodiment, a plurality of mating grooves 1112a are formed on the wall of the through hole 1111a. The plurality of mating grooves 1112a are spaced apart along the extending direction of the side wall 1112 of the receiving groove. The first pusher 1212 is provided with a plurality of spaced-apart contact portions 1212a, which respectively slide in contact with the groove wall of the mating groove 1112a. Partial structures of the plurality of contact portions 1212a are located outside the mating groove 1112a to contact and press against the workpiece 20. The extending direction of the aforementioned receiving groove is described below. Figure 4The middle arrow K. It can also be understood that multiple protrusions are provided on the side wall 1112 of the receiving groove, and the interval between adjacent protrusions is the mating groove 1112a. In conjunction with the above embodiment, the through hole 1111a is formed on the bottom wall 1111 of the receiving groove, and the mating groove 1112a is also formed on the bottom wall 1111 of the receiving groove. Thus, through multiple spaced mating grooves 1112a, while ensuring that the bottom wall 1111 of the receiving groove can support the workpiece 20, the bottom wall 1111 of the receiving groove can avoid the first pushing member 1212, preventing the first pushing member 1212 from being unable to contact and push the workpiece 20 due to the obstruction of the through hole 1111a wall.

[0060] Furthermore, the spaced-apart mating grooves 1112a on the wall of the through hole 1111a ensure the structural strength of the first pushing member 1212. Specifically, when the mating grooves 1112a are not provided on the wall of the through hole 1111a, the contact portion 1212a must extend a certain length in the first direction to ensure that it can contact and push against the workpiece 20. In this case, if the extension dimension of the contact portion 1212a is large, it is not conducive to the first driving member 1211 driving the first pushing member 1212 to move; if the extension dimension of the contact portion 1212a is small, it is not conducive to ensuring the structural strength of the contact portion 1212a and to transmitting a large pushing force to the workpiece 20. That is, it is not conducive to the correction of the workpiece 20. In this embodiment, combined with Figure 6 By providing the mating groove 1112a, it is possible to ensure that the bottom wall 1111 of the receiving groove can support the workpiece 20, while preventing the contact part 1212a from interfering with the wall of the through hole 1111a, and thus preventing the contact part 1212a from interfering with the bottom wall 1111 of the receiving groove. This allows for a larger size of the contact part 1212a, ensuring that it can transmit sufficiently large resistance pressure.

[0061] Please see Figure 6 and Figure 7 In one embodiment, at least two positioning blocks 1111c are provided on the bottom wall 1111 of the receiving groove. The workpiece 20 in the first position can contact the at least two positioning blocks 1111c. In this way, the workpiece 20 can be initially positioned by the positioning blocks 1111c, which can ensure that the straightening structure 1200 can contact and drive the workpiece 20 to move when it moves. At the same time, the initial positioning of the workpiece 20 can also reduce the displacement required by the first straightening component 1210 and the second straightening component 1220 to push the workpiece 20 to move.

[0062] Please see Figure 8In one embodiment, the second correction assembly 1220 includes a second drive member 1221 and a second push member 1222. The second drive member 1221 is connected to the second push member 1222 for driving the second push member 1222 to move along a second direction. Specifically, the second push member 1222 is capable of contacting the second side stop 22 to drive the workpiece 20 to move along the second direction until the second side stop 22 contacts the fixing fixture 1100. The second push member 1222 is used to press against the second side stop 22 when the workpiece 20 is in the second position so that the second side stop 22 contacts the fixing fixture 1100.

[0063] In the above embodiment, similar to the first pushing member 1212, the extending direction of the second pushing member 1222 can be the same as the extending direction of the second side stop 22, so as to ensure that the second pushing member 1222 can contact and press against each area on the second side stop 22. The extending directions of the second side stop 22 and the second pushing member 1222 are shown below. Figure 8 The X-axis direction in the diagram.

[0064] Furthermore, the second pusher 1222 is provided with a plurality of spaced contact portions 1212a. Similar to the first pusher 1212, the plurality of contact portions 1212a on the second pusher 1222 are also respectively slidably engaged with the groove wall of the mating groove 1112a to facilitate pressing against the workpiece 20.

[0065] Please see Figure 1 and combined Figure 6 In one embodiment, the straightening structure 1200 further includes a third straightening component 1230, which is used to press against the workpiece 20 when the workpiece 20 is in the second position. The third straightening component 1230 is capable of pressing against the workpiece 20 in a third direction so that each edge of the workpiece 20 remains in contact with the fixing fixture 1100. Figure 1 The aforementioned third party is... Figure 1 In the Z-axis direction. That is, the third correction component 1230 is used to correct the eccentricity of the workpiece 20 in the Z-axis direction. It should be understood that for a workpiece 20 whose expected shape is curved in the Z-axis direction, the shape of the fixing fixture 1100 can be adaptively adjusted so that each edge of the workpiece 20 in the second position can maintain contact with the fixing fixture 1100, thereby ensuring the correction effect of the third correction component 1230. It should be understood that the third correction component 1230 can ensure that each edge of the workpiece 20 maintains contact with the bottom wall 1111 of the receiving groove. In this way, through the first correction component 1210, the second correction component 1220 and the third correction component 1230 included in the correction structure 1200, the workpiece 20 can have a unique and definite position in space, ensuring the accuracy of the workpiece 20 mounted on the screen. It should be understood that the third direction has an angle with the plane containing the first direction and the second direction.

[0066] Please continue reading. Figure 8 In one embodiment, the third correction component 1230 includes a third driving member 1231 and a third pushing member 1232. The third driving member 1231 is connected to the third pushing member 1232 to drive the third pushing member 1232 to move along a third direction. Specifically, the third pushing member 1232 can simultaneously contact each side of the workpiece 20 to drive the entire workpiece 20, or a portion of the workpiece 20 with an offset, to move along a third direction until each side of the workpiece 20 is in contact with the bottom wall 1111 of the receiving groove. The third pushing member 1232 is used to press against each side of the workpiece 20 when the workpiece 20 is in a third position so that each side of the workpiece 20 is in contact with the bottom wall 1111 of the receiving groove.

[0067] Please refer to it again. Figure 7 In one embodiment, the fixing fixture 1100 has a plurality of suction holes 1111b for communicating with a vacuum generator (not shown, the same below). The workpiece 20 in the second position can cover the plurality of suction holes 1111b. Specifically, the vacuum suction holes 1111b can be formed on the bottom wall of the receiving groove. Thus, combined with Figure 6 Through the adsorption effect of the adsorption holes 1111b, the shape of the workpiece 20 along the Z-axis can be positioned, and the offset of the workpiece 20 in the Z-axis direction can be corrected. Similarly, the third correction component 1230 drives the workpiece 20 to move along the third direction, which can also ensure that each area on each side of the workpiece 20 can be covered by the adsorption holes 1111b, and maintain contact with the bottom wall 1111 of the receiving groove under the action of the adsorption holes 1111b, which facilitates the correction of the shape of the workpiece 20. Of course, the adsorption holes 1111b can also be opened on the side wall 1112 of the receiving groove according to actual needs to assist in the correction of each side of the workpiece 20, which will not be elaborated further.

[0068] Furthermore, when the adsorption hole 1111b is formed on the bottom wall 1111 of the receiving groove, the adsorption effect of the vacuum generator can position the workpiece 20 in the Z-axis direction, ensuring that all areas of the workpiece 20 are in contact with the bottom wall 1111 of the receiving groove. Thus, when the third correction component 1230 separates from the workpiece 20, the workpiece 20 can still maintain contact with the bottom wall 1111 of the receiving groove under the adsorption effect. This facilitates the rotation device 200 driving the correction device 100 to rotate through a preset angle. In other words, through the aforementioned adsorption effect, it can be ensured that the workpiece 20 does not undergo relative displacement with the fixed fixture 1100 during the rotation process, ensuring that the position of the workpiece 20 before and after rotation is not inconvenient relative to the position of the fixed fixture 1100. This, in turn, ensures the accuracy of the workpiece 20 mounted on the screen.

[0069] It is understandable that the structure of the adaptive correction structure 1200 can be set according to actual needs, and the above-mentioned adsorption force can be provided by means of magnetic force, electromagnetic force, etc., which will not be elaborated here.

[0070] Please see Figure 9 and Figure 10 In one embodiment, the flipping device 200 further includes a support member 220 and a drive structure 230 disposed on the support member 220. The drive structure 230 is connected to the rotating shaft 210 and is used to drive the rotating shaft 210 to rotate a preset angle. An optocoupler 240 is provided on the support member 220. When triggered, the optocoupler 240 can control the drive structure 230 to stop moving. A baffle 213 is provided on the rotating shaft 210. The baffle 213 is used to trigger the optocoupler 240 when the rotating shaft 210 rotates through the preset angle. Thus, through the cooperation of the baffle 213 and the optocoupler 240, it can be ensured that the rotating shaft 210 can accurately rotate through the preset angle.

[0071] Please continue reading. Figure 9 and Figure 10 and combined Figure 3 In one embodiment, the straightening device 100 further includes a support member 130 for supporting the fixing fixture 1100 and the straightening structure 1200. The flipping device 200 further includes a limiting structure 250. The limiting structure 250 is used to abut against the support member 130 when the rotating shaft 210 rotates through a preset angle. The limiting structure 250 is used to keep the straightening device 100 and the flipping device 200 relatively fixed. In this way, the stability of the flipping device 200 can be ensured when the feeding equipment 10 is feeding. That is, slight shaking of the straightening device 100 around the rotating shaft 210 is avoided during the feeding process of the feeding equipment 10.

[0072] Specifically, a limiting hole 131 is provided on the carrier 130, and the limiting structure 250 is used to abut against the wall of the limiting hole 131 after the correcting device 100 has rotated through a preset angle, so that the correcting device 100 and the support 220 remain relatively fixed.

[0073] Please continue reading. Figure 9 and Figure 10 In one embodiment, the rotating shaft 210 further includes a first shaft portion 211 and a second shaft portion 212 arranged concentrically. The first shaft portion 211 and the second shaft portion 212 are respectively connected to opposite sides of the support member 130. The first shaft portion 211 and the second shaft portion 212 can rotate simultaneously to drive the straightening device 100 to rotate. The above-mentioned concentric arrangement means that the central axis of the first shaft portion 211 coincides with the central axis of the second shaft portion 212.

[0074] Please continue reading. Figure 9 and Figure 10In one embodiment, the support member 220 has a tilting groove. The straightening device 100 is disposed in the tilting groove. A first shaft portion 211 is disposed on the first groove wall of the tilting groove, and a second shaft portion 212 is disposed on a second groove wall opposite to the first groove wall. The first groove wall and the second groove wall are respectively used to connect to the opposite sides of the bearing member 130.

[0075] It should be understood that, in other embodiments, the two ends of the rotating shaft 210 may be connected to the first groove wall and the second groove wall respectively. The correction device 100 is mounted on the rotating shaft 210, and when the rotating shaft 210 rotates, it can drive the correction device 100 to rotate through a preset angle.

[0076] In one embodiment, the flipping device 200 includes a plurality of limiting structures 250. The plurality of limiting structures 250 are spaced apart on the first groove wall and the second groove wall. Correspondingly, the support member 130 is provided with a plurality of limiting holes 131 for cooperating with the limiting structures 250. All the limiting holes 131 are provided on the support member 130, and the positions of the multiple limiting holes 131 are adapted to the positions of the multiple limiting structures 250.

[0077] Please see Figure 1 In a specific embodiment, taking into account various embodiments, and using the example of workpiece 20 including three side rails and the straightening structure 1200 including three straightening components, the feeding of the feeding device 10 will be described. In this embodiment, workpiece 20 is first placed on the fixed fixture 1100, and the workpiece 20 is initially positioned by the positioning block 1111c. Then, the vacuum generator is activated to adsorb workpiece 20 onto the fixed fixture 1100. Subsequently, the third straightening component 1230 is activated, causing the third pushing member 1232 to move closer to workpiece 20 along the third direction, so that each side rail of workpiece 20 is in contact with the fixed fixture 1100. Then, the second straightening component 1220 is activated, causing the second side rail 22 of workpiece 20 to move along the second direction and remain in contact with the fixed fixture 1100. When the second side rail 22 reaches the second position, the two first straightening components 1210 are activated, causing the two first side rails 21 to move in the first direction and the opposite direction, respectively, and remain in contact with the fixed fixture 1100. In this way, the correction structure 1200 completes the correction of the shape of the workpiece 20 and the positioning of the workpiece 20.

[0078] Furthermore, in the above embodiment, the preset angle can be 180°. After the workpiece 20 is corrected and positioned, the flipping device 200 can be activated to rotate the workpiece 20 180° and accurately fit it onto the screen.

[0079] Understandably, without affecting the correction and positioning of workpiece 20, the starting order of the first correction component 1210, the second correction component 1220 and the third correction component 1230 can be adjusted according to actual needs, or they can be started simultaneously.

[0080] It should be understood that for other workpieces 20 with complex shapes, multiple correction components can be added. The correction and positioning methods are the same as in the above embodiments and will not be repeated here.

[0081] 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.

[0082] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
