[0002] During the processing of a workpiece, it is usually necessary to process multiple surfaces of the workpiece.

[0037] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] Please refer to Figures 1 to 3 , which is a partial structural schematic diagram of a flipping device provided by an embodiment of the present utility model. The flipping device of this embodiment includes a workbench 100, a conveying mechanism 200, a jig mechanism 300, and a flipping mechanism 400.

[0039] The conveying mechanism 200 is arranged on the workbench 100. The jig mechanism 300 includes a jig base 310 and a workpiece fixing component 320. Among them, the conveying mechanism 200 is used to convey the jig base 310 along a preset path, the workpiece fixing component 320 is rotatably connected to the jig base 310, and the workpiece fixing component 320 is used to detachably clamp the periphery of the workpiece; among them, the conveying mechanism 200 can be a belt conveyor, a ball conveyor, or a magnetic levitation conveyor.

[0040] The flipping mechanism 400 includes a first guiding member 540, a second guiding member 640 and an intermediate guiding member 700. The first guiding member 540 is inclined and disposed on the workbench 100 and is located on the right side of the preset path. The second guiding member 640 is inclined and disposed on the workbench 100 and is located on the left side of the preset path. Moreover, the first guiding member 540 and the second guiding member 640 are staggeredly disposed on the preset path. The intermediate guiding member 700 is inclined and connected between the tops of the first guiding member 540 and the second guiding member 640. Wherein, along the conveying direction of the conveying mechanism 200, the first guiding member 540 has a first guiding surface 541 that extends obliquely upward, the second guiding member 640 has a second guiding surface 641 that extends obliquely downward, and the intermediate guiding member 700 has an intermediate guiding surface that gradually inclines from the first guiding surface 541 towards the second guiding surface 641. Wherein, when the workpiece fixing assembly 320 is conveyed by the conveying mechanism 200, it is adapted to be gradually flipped by 180 degrees under the sequential guidance of the first guiding surface 541, the intermediate guiding surface and the second guiding surface 641.

[0041] During the specific flipping process, the workpiece to be flipped is loaded on the workpiece fixing assembly 320. The conveying mechanism 200 conveys the jig mechanism 300 along the preset trajectory. The jig mechanism 300 carries the workpiece to be flipped and passes through the first guiding member 540, the intermediate guiding member 700 and the second guiding member 640 in sequence to complete the 180-degree flipping of the workpiece, wherein:

[0042] During the process that the jig mechanism 300 passes through the first guiding member 540, the lower end of the first guiding surface 541 abuts against the lower side of the handle portion 323 of the workpiece fixing assembly 320. The jig mechanism 300 continues to move forward along with the conveying mechanism 200, and the handle portion 323 of the workpiece fixing assembly 320 moves forward along the first guiding surface 541. Also, because the first guiding surface 541 extends obliquely upward, when the handle portion 323 of the workpiece fixing assembly 320 moves forward along the first guiding surface 541, the first guiding surface 541 gradually pushes the workpiece fixing assembly 320 upward to flip. When the handle portion 323 of the workpiece fixing assembly 320 passes through the upper end of the first guiding surface 541, the workpiece fixing assembly 320 is approximately flipped to a position close to 90 degrees. Thus, the workpiece on the workpiece fixing assembly 320 is flipped to a position close to 90 degrees.

[0043] When the jig mechanism 300 passes through the intermediate guide member 700, the conveying mechanism 200 continues to convey the jig mechanism 300 forward, and the handle portion 323 of the workpiece fixing assembly 320 slides from the upper end portion of the first guide surface 541 to the right end portion of the intermediate guide surface. Also, since the intermediate guide surface is inclined and extends forward, the intermediate guide surface of the intermediate guide member 700 is inclined and abuts against the handle portion 323. With this setting, the intermediate guide member 700 has a holding force to the left on the handle portion 323 of the workpiece fixing assembly 320, thereby effectively preventing the workpiece fixing assembly 320 from rotating downward. The jig mechanism 300 continues to move forward along with the conveying mechanism 200, and the intermediate guide surface of the intermediate guide member 700 pushes the workpiece fixing assembly 320 to continue to rotate upward through the handle portion 323. When the handle portion 323 of the workpiece fixing assembly 320 moves to the left end portion of the intermediate guide surface, the workpiece fixing assembly 320 is flipped more than 90 degrees. Correspondingly, the workpiece on the workpiece fixing assembly 320 is flipped more than 90 degrees.

[0044] When the jig mechanism 300 passes through the second guide member 640, the conveying mechanism 200 continues to convey the jig mechanism 300, and the handle portion 323 of the workpiece fixing assembly 320 slides from the intermediate guide surface to the upper end portion of the second guide surface 641 and moves forward along the second guide surface 641. Also, since the second guide surface 641 gradually extends downward, the second guide surface 641 of the second guide member 640 pushes the workpiece fixing assembly 320 to rotate downward through the handle portion 323. When the handle portion 323 of the workpiece fixing assembly 320 moves to the lower end portion of the second guide surface 641, the workpiece fixing assembly 320 completes a 180-degree flip. Correspondingly, the workpiece on the workpiece fixing assembly 320 completes a 180-degree flip.

[0045] As can be seen from the above, when the conveying mechanism 200 conveys the jig mechanism 300 forward, the handle portion 323 of the workpiece fixing assembly 320 relatively slides with the first guide surface 541 of the first guide member 540, the intermediate guide surface of the intermediate guide member 700, and the second guide surface 641 of the second guide member 640 in sequence. In this way, the first guide member 540, the intermediate guide member 700, and the second guide member 640 gradually push the workpiece fixing assembly 320 to flip 180 degrees, thereby completing the flipping of the workpiece on the workpiece fixing assembly 320. Among them, during the flipping of the workpiece fixing assembly 320 by the flipping mechanism 400, there is no need for an additional power source to push the workpiece fixing assembly 320 to flip 180 degrees, reducing the manufacturing cost.

[0046] In addition, in the prior art, when the conveying mechanism 200 conveys the jig mechanism 300 to a set position, the jig mechanism 300 needs to stay at this position to complete a 180-degree flip of the workpiece. In this application, during the process of the flipping mechanism 400 flipping the workpiece fixing component 320, the conveying mechanism 200 still keeps conveying the jig mechanism 300, enabling the conveying mechanism 200 to quickly convey the workpiece from the previous node to the next node, thereby improving the processing efficiency of the workpiece.

[0047] In some embodiments, referring to Figures 1 to 3 , along the conveying direction of the conveying mechanism 200, the width of the first guiding member 540 gradually increases from the lower end to the upper end, and the width of the second guiding member 640 gradually decreases from the upper end to the lower end. It can be understood that during the process of the first guiding surface 541 of the first guiding member 540 pushing the handle portion 323 of the workpiece fixing component 320 to rotate upward, the handle portion 323 of the workpiece fixing component 320 gradually moves closer to the left. The width of the first guiding member 540 gradually increases from the lower end to the upper end, causing the first guiding surface 541 to be gradually extended to the left. With this setting, during the forward movement of the workpiece fixing component 320, the end of the handle portion 323 of the workpiece fixing component 320 always remains in contact with the first guiding surface 541, and the first guiding member 540 can stably push the workpiece fixing component 320 to rotate upward. Of course, if the handle portion 323 of the workpiece fixing component 320 is set to be long enough, the first guiding surface 541 does not need to be extended to the left, and the first guiding surface 541 can also remain in contact with the handle portion 323. On the contrary, the width of the second guiding member 640 gradually decreases from the upper end to the lower end so that the second guiding surface 641 contracts to the right, so as to stably push the workpiece fixing component 320 to rotate upward.

[0048] Furthermore, the first guiding surface 541 and the second guiding surface 641 can both be set to extend in an arc or a straight line. With this setting, when the workpiece fixing component 320 moves forward, the handle portion 323 of the workpiece fixing component 320 can smoothly slide along the first guiding surface 541 and the second guiding surface 641. Therefore, the first guiding member 540 and the second guiding member 640 can smoothly act on the handle portion 323 of the workpiece fixing component 320, thereby stably pushing the workpiece fixing component 320 to rotate.

[0049] In a possible embodiment, the intermediate guide 700 can be a steel wire, the intermediate guide surface is the surface of the steel wire, and the inclination angles before and after the steel wire can be between 10 degrees and 60 degrees. Among them, the larger the inclination angle of the steel wire, the better the holding force on the workpiece fixing component 320, so that the workpiece fixing component 320 can be effectively prevented from rotating downward. It can be understood that during the sliding of the handle part 323 of the workpiece fixing component 320 along the steel wire, the steel wire has a certain deformation ability, and the steel wire can preferably abut against the handle part 323 of the workpiece fixing component 320, so that the workpiece fixing component 320 can be effectively prevented from rotating downward, and further ensure that the handle part 323 of the workpiece fixing component 320 smoothly flips to the left during the sliding along the steel wire.

[0050] In some embodiments, referring to Figures 1 to 3 , the first guide 540 is adjustably arranged on the workbench 100 along the conveying direction of the conveying mechanism 200. Thus, the first guide 540 can adjust its position along the conveying direction of the conveying mechanism 200, so as to adjust the distance between the first guide 540 and the second adjusting member; and / or, the second guide 640 is adjustably arranged on the workbench 100 along the conveying direction of the conveying mechanism 200. Thus, the second guide 640 can adjust its position along the conveying direction of the conveying mechanism 200, so as to adjust the distance between the second guide 640 and the second adjusting member. It can be understood that when the conveying force of the conveying mechanism 200 on the jig mechanism 300 is large enough, the inclination angle of the steel wire does not need to be set large, and the steel wire has a large abutting force on the handle part 323 of the workpiece fixing component 320, so as to ensure that the workpiece fixing component 320 does not rotate downward. When the conveying force of the conveying mechanism 200 on the jig mechanism 300 is small, the inclination angle of the steel wire needs to be set large, so as to ensure that the steel wire has a better holding force on the handle part 323 of the workpiece fixing component 320, so as to ensure that the workpiece fixing component 320 does not rotate downward, and ensure that the handle part 323 of the workpiece fixing component 320 can smoothly slide along the steel wire.

[0051] In order to realize the adjustable arrangement of the first guide 540 and the second guide 640 on the workbench 100, in a specific embodiment, referring to Figure 2 and Figure 4 , the flipping mechanism 400 further includes a first mounting component 500 and a second mounting component 600.

[0052] The first mounting assembly 500 includes a first guide rail base 510, a first mounting base 520, and a first locking member 550. Among them, the first guide rail base 510 is fixedly arranged on the workbench 100 along the conveying direction of the conveying mechanism 200. The first guiding member 540 is connected to the first mounting base 510. The first mounting base 520 is slidably connected to the first guide rail base 510 to adjust the distance between the first guiding member 540 and the second guiding member 640. The first locking member 550 detachably locks the first mounting base 520 to the first guide rail base 510.

[0053] The first guide rail base 510 defines a first sliding groove 511 along its length direction. A first accommodating groove 512 is formed at the bottom of the first sliding groove 511. The first sliding groove 511 and the first accommodating groove 512 penetrate through both ends of the first guide rail base 510. When the first mounting base 520 slides to a suitable position on the first guide rail base 510, the first locking member 550 passes through the first mounting base 520, the first sliding groove 511 and abuts against the first accommodating groove 512 so that the first mounting base 520 is locked to the first guide rail base 510. The first locking member 550 can be a bolt or a screw.

[0054] Specifically, when it is necessary to adjust the first guiding member 540, the staff loosens the first locking member 550, and the first mounting base 520 slides back and forth along the first guide rail base 510, thereby adjusting the position of the first guiding member 540. After the adjustment of the first guiding member 540 is completed, the staff tightens the first locking member 550. The nut or screw cap of the first locking member 550 tightly abuts against the upper top surface of the first accommodating groove 512, thereby fixing the first mounting base 520 at the corresponding position, and further fixing the first guiding member 540 at the adjusted position.

[0055] Similarly, the second mounting assembly 600 includes a second guide rail base 610, a second mounting base 620, and a second locking member 650. Among them, the second guide rail base 610 is fixedly arranged on the workbench 100 along the conveying direction of the conveying mechanism 200. The second guide rail base 610 defines a second sliding groove along its length direction. A second accommodating groove is formed at the bottom wall of the second sliding groove. The second sliding groove and the second accommodating groove penetrate through both ends of the second guide rail base 610. The second guiding member is connected to the second mounting base 620. The second mounting base 620 is slidably connected to the second guide rail base 610 to adjust the distance between the first guiding member 540 and the second guiding member 640. The second locking member 650 detachably locks the second mounting base 620 to the second guide rail base 610. The second locking member 650 can be a bolt or a screw.

[0056] Specifically, when it is necessary to adjust the second guiding member 640, the staff loosens the second locking member 650, and the second mounting seat 620 slides back and forth along the second guide rail seat 610, so as to adjust the position of the second guiding member 640. After the adjustment of the second guiding member 640 is completed, the staff tightens the second locking member 650, and the nut or screw nut of the second locking member 650 tightly abuts against the upper top surface of the second accommodating groove, so as to fix the second mounting seat 620 at the corresponding position, and further fix the second guiding member 640 at the adjusted position.

[0057] To achieve the rotational adjustment of the first guiding member 540, in a possible embodiment, refer to Figure 1 and Figure 2 , the first guiding member 540 is rotatably arranged on the first mounting seat 520, and its rotating shaft is perpendicular to the conveying path, that is, arranged left and right. Thus, the first mounting seat 520 can rotate back and forth. At the same time, the first mounting assembly 500 further includes a first scale 530, the first scale 530 is fixedly arranged on the first mounting seat 520, and the first guiding member 540 is rotatably connected to the first scale 530 through a rotating shaft. The first scale 530 is provided with scales for displaying the rotation angle of the first guiding member 540.

[0058] At the same time, to achieve the rotational adjustment of the second guiding member 640, in a possible embodiment, the second guiding member 640 is rotatably arranged on the second mounting seat 620, and its rotating shaft is perpendicular to the conveying path, that is, arranged left and right. Thus, the second mounting seat 620 can rotate back and forth. At the same time, the second mounting assembly 600 further includes a second scale 630, the second scale 630 is fixedly arranged on the second mounting seat 620, and the second guiding member 640 is rotatably connected to the second scale 630 through a rotating shaft. The second scale 630 is provided with scales for displaying the rotation angle of the second guiding member 640.

[0059] In the actual application process, due to the different specifications of the workpieces, the inclination angles of the first guiding surface 541 of the first guiding member 540 and the second guiding surface 641 of the second guiding member 640 may not be optimally applicable to the replaced workpieces. In this application, the first guiding member 540 is rotatably connected to the first dial 530. Thus, the first guiding member 540 can be rotationally adjusted to change the forward inclination angle, thereby adjusting the inclination angle of the first guiding surface 541; and, the second guiding member 640 is rotatably connected to the second dial 630. Thus, the second guiding member 640 can be rotationally adjusted to change the backward inclination angle, thereby adjusting the inclination angle of the second guiding surface 641. Among them, the operator can determine the rotation angle of the first guiding member 540 according to the first dial 530, and can determine the rotation angle of the second guiding member 640 according to the second dial 630. Thus, the operator can accurately rotate the first guiding member 540 and the second guiding member 640 to the same angle, so that the inclination angles of the first guiding surface 541 and the second guiding surface 641 are substantially the same. It can be understood that when the flipping mechanism 400 of this application is applied, the inclination angles of the first guiding member 540 and the second guiding member 640 can be flexibly adjusted, thereby adjusting the inclination angles of the first guiding surface 541 and the second guiding surface 641, and further better adapting to workpieces of various specifications.

[0060] In some embodiments, referring to Figure 3 , the workpiece fixing assembly 320 includes two workpiece mounting seats 321, a rotating shaft 322, and a handle portion 323.

[0061] The two workpiece mounting seats 321 are connected to both ends of the rotating shaft 322, and the rotating shaft 322 is rotatably connected to the jig base 310. The workpiece mounting seat 321 is used to detachably clamp the circumferential side of the workpiece. Specifically, the workpiece mounting seat 321 has a through hole, and the workpiece is clamped in the through hole. After the front surface of the workpiece is sandblasted by the sandblasting device, it is pushed and flipped by the flipping mechanism 400 and then the back surface is sandblasted. The handle portion 323 is connected to the side of the rotating shaft 322.

[0062] Furthermore, the end of the handle portion 323 is provided with a guiding arc surface 3231, and the guiding arc surface 3231 is used to relatively slide with the first guiding surface 541, the intermediate guiding surface, and the second guiding surface 641 in sequence to drive the rotating shaft 3211 to gradually rotate, so that the workpiece on the workpiece mounting seat 321 is gradually flipped by 180 degrees.

[0063] It can be understood that the end of the handle part 323 is set as the guiding arc surface 3231. With this setting, during the relative sliding process of the handle part 323 with the first guiding part 540, the middle guiding part 700 and the second guiding part 640, the friction force between them is small, so as to ensure that the handle part 323 of the workpiece fixing component 320 can slide smoothly, thereby completing the flipping of the workpiece mounting seat 321. In addition, the end of the handle part 323 is set as the guiding arc surface 3231, and the middle guiding part 700 can preferably act on the handle part 323 to the left through the guiding arc surface 3231, so as to prevent the workpiece mounting seat 321 from returning and rotating downward. Moreover, during the forward movement of the workpiece mounting seat 321, the middle guiding part 700 pushes the handle part 323 to the left through the guiding arc surface 3231, so as to ensure that the workpiece mounting seat 321 can be flipped to more than 90 degrees, and the solution can be implemented.

[0064] Further, the jig base 310 includes a mounting base plate 311, a boss 312, a first protruding part 313 and a second protruding part 314. The conveying mechanism 200 is used to convey the mounting base plate 313 along a preset path. The boss 312 protrudes from the mounting base plate 313. The first protruding part 311 protrudes from the middle position of the boss 312. The rotating shaft 322 is rotatably connected to the first protruding part 313. The two second protruding parts 314 are spaced apart on the boss 312 and are located on both sides of the first protruding part 313 to support the handle part 323 before and after flipping. The rotating shaft 322 is located between the two second protruding parts 314. When the workpiece on the workpiece mounting seat 321 is in the starting position, the second protruding part 314 on the right supports the handle part 323, so that the handle part 323 can slide onto the first guiding surface 541 (refer to Figure 2 ). After the workpiece on the workpiece mounting seat 321 is flipped 180 degrees, the second protruding part 314 on the left supports the handle part 323, so that the workpiece fixing component 320 remains in the flipped state.

[0065] It can be understood that the height of the boss 312 is greater than the flipping diameter of the workpiece. With this setting, during the rotation of the two workpiece mounting seats 321 along with the rotating shaft 322, the two workpiece mounting seats 321 will not interfere with the jig base 310, so as to ensure that the workpiece on the workpiece fixing component plate 3212 can be flipped 180 degrees.

[0066] The present application also discloses a workpiece sandblasting system, including the above-mentioned flipping device and sandblasting equipment. The sandblasting equipment is used to sandblast the workpiece on the flipping device. Specifically, it can be used to sandblast the workpiece in any one or more states before flipping, after flipping and during flipping.

[0067] It can be understood that, referring to Figure 1 and Figure 2, when the workpiece sandblasting system conveys the jig mechanism 300 forward, the handle portion 323 of the workpiece fixing assembly 320 slides relative to the first guide member 540, the intermediate guide member 700 and the second guide member 640 in sequence. Thus, the first guide member 540, the intermediate guide member 700 and the second guide member 640 gradually push the workpiece fixing assembly 320 to turn 180 degrees, thereby completing the turning of the workpiece on the workpiece fixing assembly 320. Among them, during the process of turning the workpiece fixing assembly 320 by the turning mechanism 400, there is no need for an additional power source to push the workpiece fixing assembly 320 to turn 180 degrees, which reduces the manufacturing cost, and has a simple structure, is efficient and convenient to operate, and is flexible and fast in positioning and installation.

[0068] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
