[0095] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0096] Example

[0097] Figure 1 This is a schematic diagram of the structure of a sandblasting device 1000 in one embodiment of the present application; Figure 2 for Figure 1 A schematic structural diagram of the target component 30 in the illustrated embodiment.

[0098] See also Figure 1 The embodiment of the present application provides a sandblasting device 1000 for sandblasting two sides of a target part 30 respectively.

[0099] See also Figure 2 , the target part 30 in this embodiment is a fixture for loading the workpiece to be sandblasted.

[0100] The sandblasting equipment 1000 in this embodiment includes a turning device 100 and two sandblasting machines 200 . The two sandblasting machines 200 are respectively arranged at two ends of the conveying direction A of the conveyor belt 10 .

[0101] When in use, the target part 30 enters one of the sandblasting machines 200, and the sandblasting machine 200 sandblasts one side of the workpiece loaded with the target part 30; then, the sandblasting machine 200 conveys the target part 30 to the flipping device 100, the flipping device 100 flips the target part 30 to expose the other side of the workpiece, and conveys the target part 30 to another sandblasting machine 200; the other sandblasting machine 200 sandblasts the other side of the workpiece loaded with the target part 30.

[0102] In this way, there is no need to move the target part 30 to another location for turning over, thereby improving production efficiency and meeting the production needs of high-capacity production.

[0103] In other embodiments, the target part 30 may also be a workpiece to be sandblasted, which is directly sandblasted by the sandblasting machine 200 and turned over by the turning device 100 .

[0104] Figure 2 for Figure 1 A schematic structural diagram of the target component 30 in the illustrated embodiment; Figure 3 for Figure 1 A schematic structural diagram of the flip device 100 in the first use state in the illustrated embodiment (the first connecting portion 31 is in the first position); Figure 4 for Figure 1 A schematic structural diagram of the lifting mechanism 20 in the illustrated embodiment; Figure 5 for Figure 1 A schematic diagram of a portion of the structure of the flip device 100 in the second use state in the illustrated embodiment; Figure 6 for Figure 1 The illustrated embodiment is a schematic diagram of a portion of the structure of the flip device 100 in the third use state.

[0105] See also Figures 2 to 4 This embodiment provides a turning device 100 , including a conveyor belt 10 and a lifting mechanism 20 .

[0106] The conveyor belt 10 is used to carry a target part 30 and transport the target part 30 along the conveying direction A of the conveyor belt 10. The target part 30 has front ends 30a opposite to each other along the conveying direction A (see FIG. Figure 2 ) and rear end 30b, the target part 30 is provided with a first connection portion 31, and the first connection portion 31 is located near the front end 30a. The lifting mechanism 20 is configured to be detachably connected to the first connection portion 31, and to form a rotatable fit with the target part 30 around a rotation axis parallel to the first direction B. The lifting mechanism 20 is used to drive the front end 30a to leave the conveyor belt 10 along the second direction C, so that the conveyor belt 10 can drive the rear end 30b of the target part 30 to move along the conveying direction A, thereby rotating and turning the target part 30 around the rotation axis. Among them, the first direction B, the second direction C and the conveying direction A are perpendicular to each other.

[0107] The above-mentioned turning device 100 is provided with a lifting mechanism 20, so that when the target part 30 needs to be turned over, the lifting mechanism 20 is used to drive the front end 30a of the target part 30 to leave the conveyor belt 10 along the second direction C (such as Figure 5 As shown), the rear end 30b of the target part 30 is driven by the conveyor belt 10 to move along the conveying direction A, thereby causing the target part 30 to rotate and turn over around the rotation axis parallel to the first direction B (as shown). Figure 6 As shown), that is, the rear end 30b of the target part 30 is displaced from one side of the front end 30a along the conveying direction A to the other side of the front end 30a, so that the automatic turning over of the target part 30 is achieved, and the turning over efficiency is improved.

[0108] In actual use, the above-mentioned flipping device 100 can be applied to a variety of processing scenarios for processing workpieces. For example, in the aluminum (aluminum-plastic combination) product CNC (Computer numerical control) processing industry, many burrs will be generated on the workpiece, and the burrs are mostly removed by the production process of nylon sand blasting. The sandblasting process will generate large noise and dust. By adopting the above-mentioned flipping device 100, manpower can be saved and the flipping efficiency can be improved. In addition, the impact of the sandblasting process on the health of the operator can be reduced, the cost of labor protection and auxiliary supplies can be reduced, and the labor intensity of the operator can be reduced.

[0109] In actual use, the second direction C may be a vertical direction.

[0110] It is understandable that before the lifting mechanism 20 is connected to the first connecting portion 31 for turning over, along the conveying direction A, the front end 30 a of the target part 30 is closer to the lifting mechanism 20 than the rear end 30 b.

[0111] Figure 7 for Figure 1A partial structural diagram of the flip device 100 in the fourth use state in the illustrated embodiment (the first connecting portion 31 is in the first position).

[0112] Specifically, the target part 30 has a bottom surface and a top surface that are opposite to each other along the second direction C, and the target part 30 has a first use state and a fourth use state, such as Figure 3 As shown, in the first use state, the bottom surface is in contact with the conveyor belt 10, as shown in FIG. Figure 7 As shown, in the fourth use state, the top surface is in contact with the conveyor belt 10, and the target part 30 is configured to be able to rotate and turn over around the rotation axis from the first use state to the fourth use state.

[0113] Figure 8 for Figure 1 The schematic diagram of the flipping device 100 in the embodiment shown is when the first connecting portion 31 is in the second position.

[0114] Optionally, combined Figure 3 , Figure 7 and Figure 8 As shown, the lifting mechanism 20 is configured to drive the first connecting portion 31 (see Figure 2 ) moves back and forth between the first position and the second position along the second direction C. When the first connecting portion 31 is located at the first position, the target member 30 is in the first use state (see Figure 3 ) or the fourth use state (see Figure 7 ), when the first connection part 31 is located at the second position, along the second direction C, the rear end 30b is located between the lifting mechanism 20 and the conveyor belt 10. In this way, by setting the lifting mechanism 20 to drive the first connection part 31 to move back and forth along the second direction C, after the lifting mechanism 20 drives the first connection part 31 from the first position away from the conveyor belt 10 to the second position, the lifting mechanism 20 continues to drive the first connection part 31 from the second position close to the conveyor belt 10 to the first position, that is, the first connection part 31 is placed on the conveyor belt 10 under the drive of the lifting mechanism 20, so as to prevent the target part 30 from freely falling and colliding with the conveyor belt 10, thereby reducing the vibration of the target part 30 when it contacts the conveyor belt 10 after turning over, and making the turning over process more stable.

[0115] It is understandable that if Figure 3 and Figure 7 As shown, when the first connecting portion 31 is in the first position, the first connecting portion 31 is closest to the conveyor belt 10 along the second direction C. Figure 8 As shown, when the first connecting portion 31 is in the second position, the lifting mechanism 20 drives the front end 30a to be farthest away from the conveyor belt 10 along the second direction C.

[0116] In some embodiments, Figure 4As shown, the lifting mechanism 20 includes a grabbing assembly 21 and a first driving assembly 22. The grabbing assembly 21 is used to detachably grab the first connecting portion 31 (see Figure 2 ), the first driving assembly 22 is connected to the grabbing assembly 21 to drive the grabbing assembly 21 to drive the first connecting portion 31 to move along the second direction C relative to the conveyor belt 10 (see Figure 3 Thus, by providing the grab assembly 21, the lifting mechanism 20 and the target part 30 can be connected or separated.

[0117] Alternatively, if Figure 4 As shown, the first driving assembly 22 includes a first cylinder 221 and a first piston rod 222 disposed in the first cylinder 221. The first piston rod 222 is configured to be able to move relative to the first cylinder 221 along the second direction C, and one end of the first piston rod 222 extending out of the first cylinder 221 is connected to the grabbing assembly 21. In this way, by providing the first cylinder 221 and the first piston rod 222, the first driving assembly 22 can more stably drive the front end 30a (see Figure 2 ) leaves the conveyor belt 10 along the second direction C (see Figure 5 ), thereby further improving the stability of the target part 30 when turning over.

[0118] It can be understood that the speed at which the first piston rod 222 moves relative to the first cylinder body 221 along the second direction C is configured to match the conveying speed of the conveyor belt 10, so as to further reduce the vibration of the target part 30 during the flipping process, making the flipping process more stable. Specifically, assuming that the distance between the first connecting portion 31 and the rear end 30b along the conveying direction A is L, and the distance that the first piston rod 222 drives the first connecting portion 31 to leave the conveyor belt 10 along the second direction C is h, then the distance that the rear end 30b is transported along the conveying direction A driven by the conveyor belt 10 is

[0119] In some embodiments, Figure 4 As shown, the flipping device 100 also includes a guide rail 40 extending longitudinally along the second direction C. The grabbing assembly 21 is slidably connected to the guide rail 40 along the second direction C, so that the movement of the grabbing assembly 21 along the second direction C is more stable and deflection is avoided.

[0120] In some embodiments, Figure 5 As shown, the turning device 100 further includes a base frame 50 and a support frame 60 , the conveyor belt 10 is disposed on the base frame 50 , the support frame 60 is connected to the base frame 50 , and the guide rail 40 and the lifting mechanism 20 are respectively connected to the support frame 60 .

[0121] Optionally, the guide rail 40 is disposed on a side of the support frame 60 close to the target component 30 along the first direction B to save space.

[0122] In one embodiment, the support frame 60 may be made of aluminum profiles. In other embodiments, the support frame 60 may also be made of other materials, which are not limited here.

[0123] To facilitate the grabbing assembly 21 to grab the first connecting portion 31, in some embodiments, as Figure 2 As shown, the number of the first connection parts 31 is two, and the two first connection parts 31 are respectively arranged on both sides of the target part 30 along the first direction B. Figure 4 As shown, the grabbing assembly 21 includes two clamping members 211 respectively connected to the first driving assembly 22 by transmission, and the two clamping members 211 are arranged at intervals from each other along the first direction B. The two clamping members 211 are configured to be able to approach or move away from each other along the first direction B, so that the two clamping members 211 can be connected to or separated from the two first connecting parts 31 respectively. In this way, by setting the number of the first connecting parts 31 and the clamping members 211 to two, the lifting mechanism 20 can grasp the first connecting parts 31 more conveniently and stably, thereby making the turning process of the target part 30 more stable.

[0124] Optionally, each first connection portion 31 includes a first connection hole, and a line connecting the two first connection holes is parallel to the first direction B. Figure 4 As shown, each clamping member 211 includes a clamping member body 2111 which is transmission-connected to the first driving assembly 22, and a clamping member 2112 arranged on the clamping member body 2111, and the clamping member 2112 is used to detachably engage with the corresponding first connecting hole, and can form a rotatable engagement with the corresponding first connecting hole around a rotation axis.

[0125] Specifically, the first connection portion 31 and the end surface of the front end 30a of the target part 30 have a first spacing along the conveying direction A. It can be understood that, in combination with Figure 8 As shown, by setting a larger first distance, the movement stroke of the first piston rod 222 along the second direction C can be shortened.

[0126] Alternatively, if Figure 4 As shown, the clamping member 2112 is disposed at one end of the clamping member body 2111 away from the first piston rod 222 along the second direction C to prevent the grabbing assembly 21 from interfering with the front end 30a when the target member 30 is turned over.

[0127] In order to enable the two clamping members 211 to move closer to or farther from each other along the first direction B, in some embodiments, as Figure 4As shown, the grabbing assembly 21 also includes two second drive assemblies 212 respectively connected to the first drive assembly 22, and the two second drive assemblies 212 are respectively connected to the first drive assembly 22. The two second drive assemblies 212 are arranged spaced apart from each other along the first direction B, and the two second drive assemblies 212 are respectively connected to the two gripping members 211, and each second drive assembly 212 is used to drive the corresponding gripping member 211 to move along the first direction B relative to the first drive assembly 22.

[0128] Specifically, each second driving assembly 212 is connected to the corresponding clamping member body 2111 .

[0129] Optionally, the second driving assembly 212 may be a linear cylinder, such as a three-axis cylinder.

[0130] In some embodiments, Figure 4 As shown, the grabbing assembly 21 also includes a connecting plate 213 that is transmission-connected to the first driving assembly 22, and the two second driving assemblies 212 are detachably connected to the connecting plate 213, so that the two second driving assemblies 212 are transmission-connected to the first driving assembly 22 by means of the connecting plate 213, and the two second driving assemblies 212 can move relative to the connecting plate 213 along the first direction B, so that the positions of the two second driving assemblies 212 can be adjusted according to the use requirements. For example, according to the position of the target part 30 relative to the conveyor belt 10 in the first direction B, the positions of the two second driving assemblies 212 in the first direction B relative to the conveyor belt 10 can be adjusted so that the second driving assemblies 212 can grab the target part 30.

[0131] In some embodiments, Figure 2 As shown, the target part 30 is a fixture for carrying a workpiece (not shown in the figure) to provide protection for the workpiece.

[0132] Alternatively, if Figure 2 As shown, a receiving cavity 34 for receiving a workpiece is provided in the target part 30, and through holes communicating with the receiving cavity 34 are provided on both sides of the target part 30 along the second direction C. In this way, the surface of the workpiece to be processed in the receiving cavity 34 is exposed from the through hole so as to receive surface treatment before and after turning over.

[0133] In some embodiments, Figure 2 As shown, there are multiple accommodating cavities 34 and through holes, and the accommodating cavities 34 are arranged one by one with the workpieces, and for each accommodating cavity 34, at least one through hole is arranged on both sides of the target part 30 along the second direction C to communicate with the corresponding accommodating cavity 34. In this way, a single target part 30 can be used to accommodate multiple workpieces, so that the flipping efficiency is further improved.

[0134] In some embodiments, Figure 2As shown, the number of the accommodating cavities 34 is 4. In other embodiments, the number of the accommodating cavities 34 may also be configured in other ways according to the use requirements, which is not limited here.

[0135] In some embodiments, Figure 2 As shown, the target part 30 includes a bottom plate 35 and a cover plate 36 detachably covered on the bottom plate 35 along the second direction C. The bottom plate 35 and the cover plate 36 are connected to form an accommodating cavity 34. The bottom plate 35 and the cover plate 36 are each provided with a through hole communicating with the accommodating cavity 34. The side of the bottom plate 35 away from the cover plate 36 along the second direction C has the bottom surface of the target part 30, and the side of the cover plate 36 away from the bottom plate 35 along the second direction C has the top surface of the target part 30. In actual use, before turning over the target part 30, the side of the bottom plate 35 away from the cover plate 36 along the second direction C can be attached to the conveyor belt 10. After the target part 30 is turned over by the lifting mechanism 20 and the conveyor belt 10, the side of the cover plate 36 away from the bottom plate 35 along the second direction C is attached to the conveyor belt 10, so that the side of the workpiece close to the top surface of the target part 30 is processed before turning over, and the side of the workpiece close to the bottom surface of the target part 30 is processed after turning over.

[0136] Alternatively, if Figure 2 As shown, magnets are provided on the bottom plate 35 and the cover plate 36 so that the bottom plate 35 and the cover plate 36 are fixed by magnet attraction, so that the bottom plate 35 and the cover plate 36 fit tightly when closed and are not easily separated, thereby making the turning over of the target part 30 smoother.

[0137] In other embodiments, the bottom plate 35 and the cover plate 36 may also be detachably connected by fasteners such as screws or other methods, which are not limited here.

[0138] In some embodiments, Figure 2 As shown, the target part 30 also includes a first positioning part 32 protruding from the side of the cover plate 36 facing the bottom plate 35 along the second direction C, and a recessed portion adapted to the first positioning part 32 is provided on the bottom plate 35 to make the positioning of the cover plate 36 and the bottom plate 35 more accurate.

[0139] In some embodiments, Figure 2 As shown, the target member 30 further includes a second positioning member 33 protruding from a side of the bottom plate 35 facing the cover plate 36 along the second direction C. The second positioning member 33 penetrates the cover plate 36 to allow the cover plate 36 and the bottom plate 35 to be positioned more accurately.

[0140] Optionally, the second positioning member 33 may be a positioning pin. In one embodiment, the second positioning member 33 may be a positioning pin made of steel. In other embodiments, the second positioning member 33 may be made of other materials, which is not limited here.

[0141] In some embodiments, Figure 2 As shown, the target part 30 further includes a third positioning member 39 protruding from a side of the bottom plate 35 facing the cover plate 36 along the second direction C. The third positioning member 39 is used to position the workpiece relative to the bottom plate 35 .

[0142] It is understandable that if Figure 2 As shown, since the first connecting portion 31 is disposed at a position close to the front end 30a of the target part 30, ... Figure 5 and Figure 6 As shown, when the lifting mechanism 20 drives the front end 30a to leave the conveyor belt 10 along the second direction C, the rear end 30b abuts against the conveyor belt 10 under the gravity of the target part 30, so that the rear end 30b can be displaced along the conveying direction A driven by the conveyor belt 10, so that the target part 30 rotates around the rotation axis parallel to the first direction B and turns over. In addition, since the rear end 30b is supported by the conveyor belt 10 during the turning process, the vibration of the target part 30 is reduced during the turning process, making the turning process more stable.

[0143] In some embodiments, Figure 2 As shown, the first connecting portion 31 includes a first connecting hole, the axis of the first connecting hole is parallel to the first direction B, and the first connecting hole is connected to the first connecting hole. Figure 4 As shown, the lifting mechanism 20 is provided with a clamping member 2112, which is used to be detachably matched with the first connecting hole and can form a rotatable match with the first connecting hole around the rotation axis. In this way, through the rotational match between the clamping member 2112 and the first connecting hole, the clamping member 2112 has a higher positioning accuracy relative to the first connecting hole, thereby reducing the vibration of the target part 30 during the flipping process, making the flipping process of the target part 30 more stable.

[0144] Alternatively, if Figure 2 As shown, the first connection portion 31 is disposed on the bottom plate 35 .

[0145] In some embodiments, the target part 30 has a bottom surface and a top surface opposite to each other along the second direction C, and the target part 30 has a first use state and a fourth use state, such as Figure 3 As shown, in the first use state, the bottom surface is in contact with the conveyor belt 10, as shown in FIG. Figure 7 As shown, in the fourth use state, the top surface is in contact with the conveyor belt 10, and the target part 30 is configured to be able to rotate around the rotation axis from the first use state to the fourth use state. Figure 2 As shown, the distance between the axis of the first connecting hole and the bottom surface is smaller than the distance between the axis of the first connecting hole and the top surface.

[0146] In this way, when the front end 30a of the target part 30 leaves the conveyor belt 10 driven by the lifting mechanism 20, and there is a gap between the first side of the bottom surface of the target part 30 close to the rear end 30b and the conveyor belt 10 along the second direction C, the second side of the top surface of the target part 30 close to the rear end 30b can approach the conveyor belt 10 along the second direction C under the action of gravity, so that the second side is easy to abut against the conveyor belt 10. When the second side abuts against the conveyor belt 10, the power of the conveyor belt 10 acts on the target part 30 through the second side, that is, the second side of the target part 30 is displaced along the conveying direction A driven by the conveyor belt 10, thereby making the turning process of the target part 30 smoother and avoiding the jamming phenomenon.

[0147] Specifically, Figure 8 As shown, the lifting mechanism 20 is configured so that when the target part 30 contacts the conveyor belt 10 through the second side, the lifting mechanism 20 drives the first connecting part 31 to be farthest away from the conveyor belt 10 along the second direction C, and the first connecting part 31 is in the second position.

[0148] In some embodiments, Figure 2 As shown, the target member 30 also includes a bushing 37 that is inserted into the first connecting hole, a clamping member 2112 (see Figure 4 ) can be rotatably engaged with the bushing 37 to reduce wear.

[0149] In some embodiments, in combination Figure 2 and Figure 4 As shown, the number of the first connection holes and the clamping members 2112 are both two, the two first connection holes are respectively arranged on both sides of the target part 30 along the first direction B, and the connecting line of the two first connection holes is parallel to the first direction B. The two clamping members 2112 correspond to the two first connection holes respectively, and each clamping member 2112 is used to rotatably match the corresponding first connection hole. In this way, when turning over, the lifting mechanism 20 is connected to both sides of the target part 30 along the first direction B through the two clamping members 2112, which improves the reliability of the connection between the lifting mechanism 20 and the target part 30, thereby making the turning process of the target part 30 smoother.

[0150] In some embodiments, Figure 2As shown, the target part 30 is further provided with a second connection portion 38, and the second connection portion 38 is located near the rear end 30b. The lifting mechanism 20 is configured to be detachably connected to the second connection portion 38, and to form a rotatable fit with the target part 30 around a rotation axis parallel to the first direction B. In this way, in actual use, the top surface of the target part 30 can be made to fit with the conveyor belt 10 before turning over according to the use needs, and the rear end 30b of the target part 30 is closer to the lifting mechanism 20 than the front end 30a along the conveying direction A. When turning over, the lifting mechanism 20 is connected to the second connection portion 38 to drive the rear end 30b to leave the conveyor belt 10 along the second direction C, so that the conveyor belt 10 drives the front end 30a of the target part 30 to move along the conveying direction A, and then the target part 30 is rotated around the rotation axis to turn over, and the bottom surface of the target part 30 fits with the conveyor belt 10 after turning over.

[0151] In some embodiments, Figure 1 As shown, the target parts 30 include multiple groups, and the multiple groups of target parts 30 are arranged at intervals along the first direction B. The lifting mechanism 20 includes multiple lifting mechanisms 20, and the multiple lifting mechanisms 20 are respectively arranged corresponding to the multiple groups of target parts 30, so that the flipping device 100 can flip the multiple groups of target parts 30 at the same time, further improving the flipping efficiency.

[0152] Specifically, each lifting mechanism 20 is disposed corresponding to a group of target parts 30, and each group of target parts 30 includes a plurality of target parts 30 disposed at intervals along the conveying direction A. In the actual flipping process, the plurality of target parts 30 in the same group are sequentially conveyed to the corresponding position of the lifting mechanism 20 along the conveying direction A, and each lifting mechanism 20 is used to sequentially flip the target parts 30 of the corresponding group.

[0153] Fig. 9 for Figure 1 A schematic structural diagram of the first blocking mechanism 70, the second blocking mechanism 80 and the first guide member 90 in the illustrated embodiment.

[0154] In some embodiments, Fig. 9 As shown, the flipping device 100 also includes a first blocking mechanism 70, combined with Figure 1 and Figure 2 As shown, the first blocking mechanism 70 is used to abut against the front end 30a of the target part 30 in a controllable manner along the conveying direction A, so that the target part 30 is fixed relative to the lifting mechanism 20 along the conveying direction A. In actual use, when the lifting mechanism 20 needs to be connected to the target part 30, the first blocking mechanism 70 is configured to abut against the front end 30a of the target part 30 along the conveying direction A.

[0155] In some embodiments, Fig. 9As shown, each group of target parts 30 includes a plurality of target parts 30 spaced apart from each other along the conveying direction A, and the flipping device 100 also includes a second blocking mechanism 80 spaced apart from the first blocking mechanism 70 along the conveying direction A. When the preceding target part 30 along the conveying direction A in the same group is flipped over, the second blocking mechanism 80 is configured to be able to abut against the front end 30a of the succeeding target part 30 in the same group along the conveying direction A.

[0156] Fig.10 for Figure 1 The illustrated embodiment is a schematic diagram of a portion of the structure of the flip device 100 in use.

[0157] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the target parts 30 include two groups, and the conveyor belt 10 is provided with a feeding station 11 and a discharging station 12 opposite to each other along the conveying direction A. The turning device 100 also includes a first guide member 90, which is located between the feeding station 11 and the lifting mechanism 20 along the conveying direction A, and is located between the two groups of target parts 30 along the first direction B, and the size of the first guide member 90 along the first direction B gradually increases from one end of the first guide member 90 close to the feeding station 11 along the conveying direction A to the other end of the first guide member 90.

[0158] In this way, the first guide member 90 is provided to separate the two groups of target parts 30 on both sides of the first guide member 90 along the first direction B, and the distance between the two groups of target parts 30 along the first direction B is adjusted by changing the size of the first guide member 90 along the first direction B, so that the lifting mechanism 20 is connected to the target part 30 and the target part 30 is turned over. Specifically, Fig.10 As shown, by setting the first guide member 90 from one end close to the feeding station 11 along the conveying direction A to the other end, the size of the first guide member 90 along the first direction B gradually increases, so that the spacing between the two groups of target parts 30 along the first direction B when located at the position of the lifting mechanism 20 is greater than the spacing between the two groups of target parts 30 along the first direction B when located at the feeding station 11. Therefore, under the premise of avoiding the interference between the two lifting mechanisms 20, the spacing between the two groups of target parts 30 along the first direction B when located at the feeding station 11 is smaller, so that it can be applied to more usage requirements. For example, before the target part 30 is turned over, when the workpiece loaded by the target part 30 needs to be sandblasted by the sandblasting machine 200, the spacing between the two groups of target parts 30 along the first direction B at the feeding station 11 is smaller, that is, the target parts 30 are more compactly distributed, which is conducive to reducing the size required by the sandblasting machine 200 and facilitating the cooperation with the sandblasting machine 200.

[0159] In one embodiment, Fig.10As shown, when located at the feeding station 11, the spacing between the two groups of target parts 30 along the first direction B is 35 mm, and when located at the position of the lifting mechanism 20, the spacing between the two groups of target parts 30 along the first direction B is 100 mm.

[0160] In some embodiments, Fig.10 As shown, the first guide member 90 and the conveyor belt 10 are spaced apart from each other along the second direction C to make the conveyor belt 10 transport more smoothly.

[0161] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the turning device 100 also includes a base frame 50 and a first frame body 110, the conveyor belt 10 is arranged on the base frame 50, the first frame body 110 is connected to the base frame 50, and the first guide member 90 is connected to the first frame body 110 so that the first guide member 90 is fixed relative to the base frame 50 with the help of the first frame body 110.

[0162] Fig.11 for Figure 1 A schematic structural diagram of the second guide member 120 in the illustrated embodiment.

[0163] In some embodiments, in combination Fig.10 and Fig.11 As shown, the target parts 30 include two groups, and the conveyor belt 10 is provided with a feeding station 11 and a discharging station 12 which are opposite to each other along the conveying direction A. The turning device 100 also includes two second guide members 120, and the two second guide members 120 are located between the discharging station 12 and the lifting mechanism 20 along the conveying direction A. The two second guide members 120 are arranged to be spaced apart from each other along the first direction B, and a discharging channel 121 for the target parts 30 to pass along the conveying direction A is defined between the two second guide members 120, and the size of the discharging channel 121 along the first direction B gradually decreases from one end of the discharging channel 121 close to the lifting mechanism 20 along the conveying direction A to the other end of the discharging channel 121.

[0164] In this way, two second guide members 120 are provided to limit the sides of the two groups of target parts 30 that are away from each other along the first direction B, that is, the distance between the two groups of target parts 30 along the first direction B is adjusted by changing the size of the discharge channel 121 along the first direction B. Specifically, the size of the discharge channel 121 along the first direction B is gradually reduced from one end of the discharge channel 121 close to the lifting mechanism 20 along the conveying direction A to the other end, so as to avoid interference between the two lifting mechanisms 20 when turning over, and make the distance between the two groups of target parts 30 along the first direction B when located at the discharge station 12 smaller than the distance between the two groups of target parts 30 along the first direction B when located at the lifting mechanism 20, so as to meet more usage requirements. For example, when it is necessary to use a sandblasting machine 200 to perform sandblasting after the target part 30 is turned over, the distance between the two groups of target parts 30 along the first direction B at the discharge station 12 is smaller, so as to facilitate cooperation with the sandblasting machine 200.

[0165] In one embodiment, when located at the lifting mechanism 20 , the spacing between the two groups of target parts 30 along the first direction B is 100 mm, and when located at the unloading station 12 , the spacing between the two groups of target parts 30 along the first direction B is 35 mm.

[0166] In some embodiments, Fig.10 As shown, the second guide member 120 and the conveyor belt 10 are spaced apart from each other along the second direction C to make the conveyor belt 10 transport more smoothly.

[0167] In some embodiments, Fig.10 and Fig.11 As shown, the flipping device 100 also includes a base frame 50 and a second frame 130, the conveyor belt 10 is arranged on the base frame 50, the second frame 130 is connected to the base frame 50, and the two second guide members 120 are respectively connected to the second frame 130, so that the two second guide members 120 are fixed relative to the base frame 50 with the help of the second frame 130.

[0168] In order to improve the positioning accuracy of the target part 30 when turning over, in some embodiments, Figure 8 and Fig. 9 As shown, the flipping device 100 also includes a flipping positioning assembly 140 arranged between the lifting mechanism 20 and the conveyor belt 10 along the second direction C. The flipping positioning assembly 140 is used to position the target part 30 relative to the conveyor belt 10 along the first direction B so that the lifting mechanism 20 is connected to the target part 30.

[0169] In some embodiments, in combination Figure 7 and Fig. 9As shown, the flip positioning assembly 140 includes two first flip positioning structures 141 spaced apart from each other along the first direction B. Along the first direction B, the target part 30 is located between the two first flip positioning structures 141, so that the two sides of the target part 30 along the first direction B are limited by the two first flip positioning structures 141 respectively.

[0170] Optionally, the target parts 30 include two groups, and along the first direction B, the two groups of target parts 30 are located between two first flip positioning structures 141, so that the two groups of target parts 30 are limited on one side away from each other along the first direction B by the two flip positioning structures.

[0171] Specifically, the first flipping and positioning structure 141 is connected to the base frame 50 .

[0172] In some embodiments, in combination Figure 7 and Fig. 9 As shown, the target parts 30 include two groups, and the flip positioning assembly 140 also includes a second flip positioning structure 142. Along the first direction B, the second flip positioning structure 142 is located between the two groups of target parts 30 to limit the two groups of target parts 30 on one side close to each other along the first direction B through the second flip positioning structure 142.

[0173] Optionally, the second flipping and positioning structure 142 is connected to the support frame 60 .

[0174] In this way, by setting up the flip positioning assembly 140, the positioning accuracy of the target part 30 relative to the conveyor belt 10 is improved, so that when it is necessary to flip it, it is convenient to connect the lifting mechanism 20 with the target part 30, and it is beneficial to improve the positioning accuracy when the lifting mechanism 20 is connected with the first connecting part 31.

[0175] Fig.12 Schematic diagram of the structure of the protective cover 150 in one embodiment of the present application.

[0176] In some embodiments, Fig.12 As shown, the flipping device 100 also includes a cover arranged on the lifting mechanism 20 (see Fig.10 ) is provided with a protective cover 150 outside to provide protection.

[0177] Optionally, the protective cover 150 may be made of an acrylic plate so that the turning process of the target part 30 can be observed through the protective cover 150 .

[0178] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
