[0100] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings.

[0101] Please refer to Figure 1 、 Figure 2 and Figure 3 together. The turning and spacing-changing device 100 provided by the embodiment of the present application is used to turn the workpiece 10 and adjust the spacing between the workpieces 10. The turning and spacing-changing device 100 includes a carrying mechanism 20, a turning mechanism 30, an adsorbing mechanism 40 and a spacing-changing mechanism 50. The carrying mechanism 20 is used to carry a plurality of workpieces 10. The turning mechanism 30 includes a turning carrier plate 31. The turning carrier plate 31 is rotatably arranged on one side of the carrying mechanism 20 and rotates between a first position 32 and a second position 33. When the turning carrier plate 31 is in the first position 32, it is spaced from the carrying mechanism 20. When the turning carrier plate 31 is in the second position 33, it is arranged opposite to the carrying mechanism 20. The adsorbing mechanism 40 includes a carrying plate 41 and multiple groups of adsorbing members 42. The carrying plate 41 is located on one side of the turning carrier plate 31. A through hole 311 extending in the first direction X is provided on the turning carrier plate 31. Multiple groups of adsorbing members 42 are arranged on the carrying plate 41. At least part of the adsorbing members 42 is slidably connected to the carrying plate 41. Each group of adsorbing members 42 extends into the through hole 311 to adsorb the workpiece 10. The spacing-changing mechanism 50 includes a spacing-changing member 51 and a driving member 52. The spacing-changing member 51 is slidably connected to the carrying plate 41 along the first direction X. The spacing-changing member 51 is sequentially provided with a plurality of spacing-changing grooves 511 along the first direction X. The lengths of the plurality of spacing-changing grooves 511 increase or decrease sequentially in the first direction X. Each group of adsorbing members 42 slidably connected to the carrying plate 41 is arranged in one spacing-changing groove 511. The driving member 52 is connected to the carrying plate 41, and the driving member 52 is configured to drive the spacing-changing member 51 to move along the first direction X, so as to drive the adsorbing members 42 in the plurality of spacing-changing grooves 511 to move relative to the carrying plate 41 to adjust the spacing between the adsorbing members 42.

[0102] In the above-mentioned turning and pitch-changing device 100, the turning carrier plate 31 is turned from the first position 32 to the second position 33. After the suction member 42 connected to the turning carrier plate 31 adsorbs the workpiece 10 on the carrying mechanism 20, the turning carrier plate 31 is reset from the second position 33 to the first position 32 to achieve the purpose of turning the workpiece 10. By means of the driving member 52 cooperating with the pitch-changing member 51, the suction member 42 slides in the pitch-changing groove 511 to adjust the distance between two adjacent groups of suction members 42, so as to achieve the purpose of pitch-changing of the workpiece 10 adsorbed by the suction member 42, thereby improving the processing efficiency of the workpiece 10.

[0103] Please refer to Figure 2 、 Figure 3 and Figure 4 as well. In some embodiments, the pitch-changing mechanism 50 further includes a limiting member 53. The limiting member 53 is connected to the side of the carrying plate 41 facing the turning carrier plate 31 and is disposed adjacent to the pitch-changing member 51. The limiting member 53 is provided with a limiting groove 531 along the first direction X. At least one group of suction members 42 slidably connected to the carrying plate 41 is also disposed in the limiting groove 531. The limiting groove 531 is configured to limit the sliding stroke of the suction member 42 in the first direction X, and the suction member 42 is configured to be clamped between the groove wall of the pitch-changing groove 511 and the groove wall of the limiting groove 531. By providing the limiting member 53, when the driving member 52 drives the pitch-changing member 51 to move, the suction member 42 slides in the pitch-changing groove 511 and also slides in the limiting groove 531. The limiting groove 531 limits the sliding stroke of the suction member 42 in the first direction X, thereby improving the pitch-changing accuracy between the workpieces 10 after the distance adjustment.

[0104] Optionally, the limiting member 53 is provided with a plurality of limiting grooves 531, and each group of suction members 42 slidably connected to the carrying plate 41 is also disposed in one limiting groove 531.

[0105] Please refer to Figure 3 、 Figure 4 and Figure 5 as well. In this embodiment, the turning and pitch-changing device 100 (refer to Figure 1 ) includes 4 groups of suction members 42, namely the first suction member 421, the second suction member 422, the third suction member 423 and the fourth suction member 424. The first suction member 421, the second suction member 422, the third suction member 423 and the fourth suction member 424 are sequentially disposed on the side of the carrying plate 41 facing the turning carrier plate 31 along the first direction X, wherein the fourth suction member 424 is fixedly connected to the carrying plate 41.

[0106] Accordingly, the pitch-changing member 51 is provided with a first pitch-changing groove 5111, a second pitch-changing groove 5112, and a third pitch-changing groove 5113. The first attracting member 421 is disposed in the first pitch-changing groove 5111, the second attracting member 422 is disposed in the second pitch-changing groove 5112, and the third attracting member 423 is disposed in the third pitch-changing groove 5113. Since the first attracting member 421 is exactly clamped in the first pitch-changing groove 5111, the length of the first pitch-changing groove 5111 is less than the length of the second pitch-changing groove 5112, and the length of the second pitch-changing groove 5112 is less than the length of the third pitch-changing groove 5113.

[0107] The limiting member 53 is provided with a first limiting groove 5311 and a second limiting groove 5312. The second limiting groove 5312 is disposed between the first limiting groove 5311 and the fourth attracting member 424. At this time, the second attracting member 422 is located in the second pitch-changing groove 5112 and also in the first limiting groove 5311. The third attracting member 423 is located in the third pitch-changing groove 5113 and also in the second limiting groove 5312. The length of the first limiting groove 5311 is greater than the length of the second limiting groove 5312, and the length of the first limiting groove 5311 is equal to the length of the third pitch-changing groove 5113, and the length of the second limiting groove 5312 is equal to the length of the second pitch-changing groove 5112.

[0108] Specifically, with the fourth attracting member 424 as a reference, the specific steps for the pitch-changing member 51 to cooperate with the driving member 52 to drive the first attracting member 421, the second attracting member 422, and the third attracting member 423 to adjust the distance relative to the fourth attracting member 424 are as follows:

[0109] The pitch-changing member 51 moves along the first direction X toward the fourth attracting member 424 by the length of the third pitch-changing groove 5113 under the drive of the driving member 52. The third attracting member 423 located in the third pitch-changing groove 5113 is abutted by the groove wall of the third pitch-changing groove 5113 until the third attracting member 423 abuts the groove wall of one end of the second limiting groove 5312 close to the fourth attracting member 424. At this time, after the pitch-changing member 51 moves by the length of the third pitch-changing groove 5113, the second attracting member 422 located in the second pitch-changing groove 5112 also moves in the first limiting groove 5311. Since the length of the first limiting groove 5311 is equal to the length of the third pitch-changing groove 5113, when the pitch-changing member 51 moves by the length of the third pitch-changing groove 5113, the second attracting member 422 is clamped between the second pitch-changing groove 5112 and the groove wall of one end of the first limiting groove 5311 close to the fourth attracting member 424.

[0110] Driven by the driving member 52, the pitch-changing member 51 moves along the first direction X by the length of the second pitch-changing slot 5112 away from the fourth suction member 424, causing the third suction member 423 located within the third pitch-changing slot 5113 to move away from the fourth suction member 424 until the third suction member 423 abuts against the wall of the second limiting slot 5312 at the end away from the fourth suction member 424. At this point, the third suction member 423 is retained between the wall of the second limiting slot 5312 and the wall of the third pitch-changing slot 5113, thereby adjusting the distance between the third suction member 423 and the fourth suction member 424. At this point, after the second suction member 422 located within the second pitch-changing slot 5112 has moved by the length of the second pitch-changing slot 5112, the second suction member 422 is retained between the wall of the second pitch-changing slot 5112 and the wall of the first limiting slot 5311 at the end away from the fourth suction member 424, thereby adjusting the distance between the second suction member 422 and the third suction member 423.

[0111] It is understandable that when the lengths of the multiple pitch-changing slots 511 in the pitch-changing member 51 along the first direction X are equal, the lengths of the multiple limiting slots 531 in the limiting member 53 along the first direction X are also equal. At this time, when the pitch-changing member 51 moves with the fourth adsorption member 424 as a reference, the second adsorption member 422 located in the second pitch-changing slot 5112 and the third adsorption member 423 located in the third pitch-changing slot 5113 move by the length of one pitch-changing slot 511. At this time, the second adsorption member 422 is exactly stuck between the second pitch-changing slot 5112 and the slot wall of the first limiting slot 5311, and the third adsorption member 423 is exactly stuck between the slot wall of the third pitch-changing slot 5113 and the slot wall of the second limiting slot 5312, thereby achieving an equal distance between two adjacent adsorption members 42 after the spacing adjustment.

[0112] Please also refer to Figure 2 and Figure 3 In some embodiments, the driving member 52 includes a variable pitch driving portion 521 and a pushing portion 522. The carrier plate 41 is provided with a sliding hole 411. The variable pitch driving portion 521 is connected to the side of the carrier plate 41 facing away from the flip carrier plate 31. One end of the pushing portion 522 is connected to the transmission end of the variable pitch driving portion 521, and the other end passes through the sliding hole 411 to connect to the variable pitch member 51, thereby enabling the variable pitch member 51 to move in the first direction X.

[0113] Please continue reading Figure 2 and Figure 3, in some embodiments, the pitch-changing mechanism 50 further includes a limiting block 54, and the limiting block 54 is connected to the side of the bearing plate 41 facing away from the flipping carrier plate 31. The limiting block 54 is provided with a sliding groove 541, and the pushing portion 522 is slidably disposed in the sliding groove 541 along the first direction X. The sliding groove 541 reduces the risk of the pushing portion 522 detaching from the bearing plate 41, and at the same time, the sliding groove 541 also limits the sliding stroke of the pushing portion 522 driving the pitch-changing member 51 in the first direction X.

[0114] Please refer to Figure 3 and Figure 4 , in some embodiments, the adsorption mechanism 40 further includes a first guiding member 43, and the first guiding member 43 includes a first guiding slide rail 431 and a plurality of first guiding sliders 432. The first guiding slide rail 431 is connected to the side of the bearing plate 41 facing the flipping carrier plate 31. The first guiding slider 432 is connected to the adsorbing member 42 slidably connected to the bearing plate 41, and the first guiding slider 432 is slidably connected to the first guiding slide rail 431 along the first direction X. Through the above arrangement, when the pitch-changing member 51 drives the adsorbing member 42 to move along the first direction X, the adsorbing member 42 drives the first guiding slider 432 to move along the first guiding slide rail 431, reducing the risk of the adsorbing member 42 deviating from the moving track during the moving process.

[0115] Please continue to refer to Figure 3 and Figure 4 , in some embodiments, each group of adsorbing members 42 includes a mounting base 425 and two suction nozzles 426. The mounting base 425 is disposed in the pitch-changing groove 511 and the limiting groove 531. The two suction nozzles 426 are spaced apart on the mounting base 425, and the end of the suction nozzle 426 away from the mounting base 425 passes through the through hole 311 and extends into the flipping carrier plate 31. The suction nozzle 426 is used to adsorb the workpiece 10. The two suction nozzles 426 improve the stability of the adsorbing member 42 when adsorbing the workpiece 10. It can be understood that, to adapt to the sizes of different workpieces 10, the number of suction nozzles 426 on each mounting base 425 can be any one of the numbers such as 1, 3, 4, 5, etc., improving the versatility of the adsorbing member 42.

[0116] Please continue to refer to Figure 3 and Figure 4 , in some embodiments, the adsorption mechanism 40 further includes a first lifting member 44, and the first lifting member 44 is connected to the bearing plate 41. The first lifting member 44 is configured to drive the bearing plate 41 to move relative to the flipping carrier plate 31 along the second direction Y, so that the adsorbing member 42 passes through the through hole 311 to adsorb the workpiece 10, and the first direction X is perpendicular to the second direction Y. Through the above arrangement, the first lifting member 44 drives the bearing plate 41 and the adsorbing member 42 disposed on the bearing plate 41 to extend out of the through hole 311 to adsorb the workpiece 10.

[0117] Please continue to refer to Figure 3 and Figure 4In some embodiments, the adsorption mechanism 40 further includes a second guide member 45, which includes a second guide rail 451 and a second guide slider 452. The second guide rail 451 is disposed on the side of the flip carrier 31 facing the carrier plate 41. The second guide slider 452 is slidably connected to the second guide rail 451 along the second direction Y, and the carrier plate 41 is connected to the second guide slider 452. When the first lifting member 44 drives the carrier plate 41 to move along the second direction Y, the carrier plate 41 drives the second guide slider 452 to move along the second guide rail 451, thereby reducing the risk of the carrier plate 41 deviating from its trajectory during movement.

[0118] The second guide member 45 further includes a mounting bracket 453, which is connected to the side of the flip carrier 31 facing the support plate 41 and is located on the side of the support plate 41 facing away from the first lifting member 44. The first guide rail 431 is connected to the side of the mounting bracket 453 facing the support plate 41. The mounting bracket 453 improves the stability of the support plate 41 when it moves relative to the flip carrier 31.

[0119] Please also refer to Figure 1 and Figure 6 In some embodiments, the flip-shift device 100 further includes two support members 60 spaced apart along a first direction X. The support mechanism 20 is configured to be slidably connected between the two support members 60 along a second direction Y. The support mechanism 20 is further configured to be telescopically disposed between the two support members 60 along a third direction Z. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular. Providing two support members 60 to support the support mechanism 20 improves the stability of the workpiece 10 when positioned on the support mechanism 20.

[0120] Specifically, the support mechanism 20 includes a support member 21 and a second lifting member 22. The support member 21 is disposed between two support members 60 and is used to support the workpiece 10. Slide bars 61 are provided on opposing sides of the two support members 60, and the support member 21 is slidably disposed between the two slide bars 61. The second lifting member 22 is connected to the support member 21 and is configured to drive the support member 21 to move in the third direction Z.

[0121] When the carrier 21 drives the workpiece 10 to slide along the slide bar 61 to a preset position, the flip carrier 31 rotates from the first position 32 to the second position 33. At this time, the second lifting member 22 drives the carrier 21 to move along the third direction Z toward the flip carrier 31 located at the second position 33. The first lifting member 44 drives the carrier plate 41 and the suction member 42 connected to the carrier plate 41 to extend out of the through hole 311 of the flip carrier 31 to suction the workpiece 10 on the carrier 21, thereby achieving the purpose of suctioning the workpiece 10 so that the workpiece 10 can be subsequently flipped and the spacing adjusted.

[0122] Please also refer toFigure 6 and Figure 7 ,In some embodiments, the flipping mechanism 30 further includes a flipping member 34. The flipping member 34 includes two brackets 341 and a flipping driving portion 342. Each bracket 341 is connected to a support member 60. The flipping carrier plate 31 is disposed between the two brackets 341. The flipping driving portion 342 is connected to one of the brackets 341 and is drivingly connected to the flipping carrier plate 31. The flipping driving portion 342 is configured to drive the flipping carrier plate 31 to rotate relative to the bracket 341 about an axis O, and the axis O is parallel to the first direction X. Through the above arrangement, the flipping driving portion 342 drives the flipping carrier plate 31 to rotate relative to the bracket 341, so that the flipping carrier plate 31 can flip between the first position 32 and the second position 33 to drive the workpiece 10 to achieve flipping.

[0123] The flipping member 34 further includes two connecting plates 343. Each connecting plate 343 is connected to a side of one bracket 341 facing the other bracket 341. Each connecting plate 343 has a first end 3431 and a second end 3432 which are oppositely arranged. The flipping carrier plate 31 is connected between the first ends 3431 of the two connecting plates 343. The flipping driving portion 342 is connected to one of the connecting plates 343. Through the above arrangement, the two connecting plates 343 drive the flipping carrier plate 31 to achieve flipping under the drive of the flipping driving portion 342.

[0124] Please continue to refer to Figure 6 and Figure 7 ,In some embodiments, the flipping member 34 further includes two counterweight blocks 344. Each counterweight block 344 is connected to the second end 3432. The two counterweight blocks 344 are used to balance the weight of the flipping carrier plate 31 during the flipping process, and at the same time improve the stability of the flipping carrier plate 31 when it is in the first position 32 or the second position 33.

[0125] Please continue to refer to Figure 6 and Figure 7 ,In some embodiments, the flipping mechanism 30 further includes a first abutting member 35 and a second abutting member 36. The first abutting member 35 is provided with two abutting ends 351 which are spaced apart along the second direction Y. The second abutting member 36 is connected to a side of the connecting plate 343. The second abutting member 36 is configured to abut against any one of the abutting ends 351 when the flipping carrier plate 31 rotates to the first position 32 or the second position 33. When the flipping carrier plate 31 flips to the first position 32 or the second position 33, the second abutting member 36 abuts against one of the abutting ends 351 to improve the accuracy of the flipping driving portion 342 driving the flipping carrier plate 31 to rotate to the first position 32 or the second position 33.

[0126] Please continue to refer to Figure 6 and Figure 7, in some embodiments, the flipping mechanism 30 further includes two buffer members 37, and each buffer member 37 is connected to a side of the abutting end 351 away from the connecting plate 343. The buffer member 37 is configured to elastically abut against the second abutting member 36 when the flipping carrier plate 31 is rotated to the first position 32 or the second position 33, and the two buffer members 37 improve the stability when the flipping carrier plate 31 is rotated to the first position 32 or the second position 33.
