[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0039] The following is for reference. Figure 1 and Figure 2 The relay module 10 of the present invention will be described in detail.

[0040] Reference Figure 1 According to an embodiment of the present invention, the transfer module 10 includes a frame 100 and a flipping mechanism 200.

[0041] The frame 100 is provided with a loading area 110 and a loading area 120. The loading area 110 is used to store sandblasting fixtures, and the loading area 120 is used to store cleaning fixtures. The flipping mechanism 200 is provided on the frame 100 and is located between the loading area 110 and the loading area 120. The flipping mechanism 200 includes a drive assembly 210, a flipping frame 220, a first clamping assembly 230 and a second clamping assembly 240. The first clamping assembly 230 and the second clamping assembly 240 are both provided on the flipping frame 220, and the drive assembly 210 is connected to the flipping frame 220.

[0042] For example, such as Figure 1 and Figure 2As shown, a loading area 110 and a loading area 120 are provided on the frame 100, with the loading area 110 located in front of the loading area 120. A flipping mechanism 200 is disposed between the loading area 110 and the loading area 120. The flipping mechanism 200 includes a drive assembly 210, a flipping frame 220, a first clamping assembly 230, and a second clamping assembly 240. The edge of the flipping frame 220 is hinged between the loading area 110 and the loading area 120. The drive assembly 210 is connected to the flipping frame 220. Under the drive of the drive assembly 210, the flipping frame 220 can flip back and forth, so that the flipping frame 220 moves into the loading area 110.

[0043] Alternatively, the flipping frame 220 can be moved into the loading area 120. The first clamping component 230 and the second clamping component 240 are both disposed on the flipping frame 220. When the flipping frame 220 is flipped into the loading area 110, the first clamping component 230 is located below the second clamping component 240. When the flipping frame 220 is flipped into the loading area 120, the second clamping component 240 is located below the first clamping component 230.

[0044] It is understood that when the transfer module 10 of the present invention is working, an empty sandblasting fixture can be placed in the loading area 110, and a cleaning fixture fully loaded with workpieces can be placed in the loading area 120. Under the drive of the drive component 210, the flipping frame 220 can flip forward so that the flipping frame 220 moves into the loading area 110. At this time, the first clamping component 230 can clamp the sandblasting fixture in the loading area 110. Then, the drive component 210 can drive the flipping frame 220 to flip backward so that the flipping frame 220 flips into the loading area 120. At this time, the sandblasting fixture can be inverted onto the cleaning fixture, and The second clamping component 240 can clamp the cleaning fixture; then, the driving component 210 can drive the flipping frame 220 to flip forward, so that the flipping frame 220 flips again into the loading area 110. At this time, the workpiece in the cleaning fixture can be turned upside down into the sandblasting fixture, so as to realize the transfer of the workpiece from the cleaning fixture to the sandblasting fixture, and the workpiece can be flipped over when it is transferred into the sandblasting fixture; then, the first clamping component 230 releases the sandblasting fixture, and the driving component 210 drives the flipping frame 220 to flip backward, so as to move the empty cleaning fixture back into the loading area 120; then, the second clamping component 240 releases the cleaning fixture. Therefore, in the transfer module 10 of this embodiment, the transfer module 10 can automatically flip and transfer the workpiece in the cleaning fixture into the sandblasting fixture, reducing the workload of the workers and saving time and effort.

[0045] It is understandable that, since the flip frame 220 is equipped with both the first clamping component 230 and the second clamping component 240, and when the transfer module 10 is working, there is a situation where the first clamping component 230 clamps the sandblasting fixture while the second clamping component 240 also clamps the cleaning fixture. In this case, it is necessary to avoid mutual interference between the sandblasting fixture and the cleaning fixture.

[0046] To address the above problems, in a further embodiment of the present invention, reference is made to... Figure 2 The first clamping assembly 230 includes a first driver 231 and a plurality of first clamping structures 232. The plurality of first clamping structures 232 surround to form a first receiving cavity for accommodating a sandblasting fixture. The first driver 231 is connected to each of the first clamping structures 232 and is used to drive the first clamping structures 232 to move closer to or away from the first receiving cavity. The second clamping assembly 240 includes a second driver 241 and a plurality of second clamping structures 242. The plurality of second clamping structures 242 surround to form a second receiving cavity for accommodating a cleaning fixture. The second driver 241 is connected to each of the second clamping structures 242 and is used to drive the second clamping structures 242 to move closer to or away from the second receiving cavity. The second receiving cavity is located on one side of the first receiving cavity and communicates with the first receiving cavity.

[0047] It is understandable that, since multiple first clamping structures 232 surround to form a first receiving cavity and multiple second clamping structures 242 surround to form a second receiving cavity, when the first clamping assembly 230 clamps the sandblasting fixture and the second clamping assembly 240 clamps the cleaning fixture, the sandblasting fixture can be accommodated in the first receiving cavity and the cleaning fixture can be accommodated in the second receiving cavity, and the sandblasting fixture and the cleaning fixture do not interfere with each other; at the same time, since the first receiving cavity and the second receiving cavity are connected, the workpiece in the cleaning fixture can normally enter the sandblasting fixture.

[0048] For example, when the flipping frame 220 is flipped into the loading area 120, the first receiving cavity can be located above the second receiving cavity; when the flipping frame 220 is flipped into the loading area 110, the first receiving cavity can be located below the second receiving cavity.

[0049] For details, please refer to Figure 2 Here, the first clamping assembly 230 is described in detail when the flipping frame 220 is located in the loading area 120: The first clamping assembly 230 includes a first driver 231 and four first clamping structures 232. The first clamping structure 232 can be a locking member. The front edge and the rear edge of the flipping frame 220 are each provided with two locking members. The first driver 231 includes four first cylinders. The four first cylinders correspond one-to-one with the four locking members and are connected. The first cylinders can drive the locking members connected to them to move closer to or away from the first receiving cavity in order to clamp or release the sandblasting fixture in the first receiving cavity.

[0050] For details, please refer to Figure 2 Here, the second clamping assembly 240 is described in detail with the flipping frame 220 located in the loading area 120: The second clamping assembly 240 includes a second driver 241 and two second clamping structures 242. The two second clamping structures 242 are located on the left and right edges of the flipping frame 220, and the second clamping structures 242 are slidably arranged in the left and right direction. The second driver 241 includes two second cylinders, which are respectively connected to the two second clamping structures 242. The second cylinders can drive the second clamping structures 242 connected to them to move left and right to move closer to or away from the second receiving cavity. The second clamping structure 242 includes a thumb cylinder 242a and a gripper 242b. The thumb cylinder 242a and the gripper 242b are connected. Under the drive of the thumb cylinder 242a, the gripper 242b can clamp or release the edge of the cleaning fixture located in the second receiving area.

[0051] Understandably, if the workpieces in the cleaning fixture are transferred to the sandblasting fixture, and the empty cleaning fixtures in the loading area 120 or the fully loaded sandblasting fixtures in the loading area 110 are replaced manually, it will undoubtedly greatly increase labor costs.

[0052] To reduce labor costs, refer to Figure 1 In some embodiments of the present invention, the frame 100 is further provided with a material unloading area 130 and a material unloading area 140. The material unloading area 130 is located to the right of the material loading area 110, and the material unloading area 140 is located to the right of the material loading area 120. The frame 100 is also provided with a first conveyor line 101 for conveying sandblasting fixtures and a second conveyor line 102 for conveying cleaning fixtures. The first conveyor line 101 extends in the left-right direction and passes through the material loading area 110 and the material unloading area 130. The first conveyor line 101 can convey the sandblasting fixtures from right to left. The second conveyor line 102 extends in the left-right direction and passes through the material loading area 120 and the material unloading area 140. The second conveyor line 102 can convey the cleaning fixtures from left to right. Furthermore, when the sandblasting fixture in the loading area 110 is fully loaded, the fully loaded sandblasting fixture can be conveyed to the left along the first conveyor line 101 to leave the loading area 110. Then, another empty sandblasting fixture that has finished unloading workpieces in the unloading area 130 can be conveyed to the loading area 110 along the first conveyor line 101 to wait for workpiece loading. When the cleaning fixture in the loading area 120 is empty, the empty cleaning fixture can be conveyed to the right along the second conveyor line 102 to the unloading area 140 to receive workpieces unloaded from the sandblasting fixture in the unloading area 130. Then, another fully loaded cleaning fixture can be conveyed to the right along the second conveyor line 102 to the loading area 120.

[0053] Further reference Figure 1The transfer module 10 also includes a conveying mechanism 300, which is mounted on the frame 100 and is used to convey the workpieces located on the sandblasting fixture in the unloading area 130 to the cleaning fixture located in the unloading area 140.

[0054] It is understood that the input end of the first conveyor line 101 can be connected to the output end of the sandblasting module 20, and the output end of the first conveyor line 101 can be connected to the input end of the sandblasting module 20. The sandblasting fixture output by the sandblasting module 20 can be conveyed along the first conveyor line 101 to the unloading position. Then, the conveying mechanism 300 will move the workpiece on the sandblasting fixture at the unloading position to the cleaning fixture at the unloading position. Then, the empty sandblasting fixture can be conveyed along the first conveyor line 101 to the loading position to wait for the workpiece to be loaded. After the workpiece is loaded at the loading position, the sandblasting fixture can be conveyed along the first conveyor line 101 to the input end of the sandblasting module 20. After the workpiece in the cleaning fixture at the loading position is transferred to the sandblasting fixture, the empty cleaning fixture can be conveyed along the second conveyor line 102 to the unloading position and receive the workpiece moved by the conveying mechanism 300 from the fully loaded sandblasting fixture at the unloading position.

[0055] Further reference Figure 1 In a further embodiment of the present invention, the transfer module 10 further includes a plug removal and installation mechanism (not shown in the figure). The plug removal and installation mechanism is disposed on the frame 100. The frame 100 is also provided with a plug loading area 150 and a plug suction area 160, both located on the first conveying line 101. Along the conveying direction of the first conveying line 101, the plug loading area 150 is located behind the loading area 110, and the plug suction area 160 is located in front of the unloading area 130. The plug removal and installation mechanism is used to remove the plugs in the sandblasting fixture located in the plug suction area 160 and install the plugs on the sandblasting fixture located in the plug loading area 150.

[0056] Understandably, by setting up a plug removal and installation mechanism, the plug can be installed on the workpiece of the sandblasting fixture before the sandblasting fixture enters the sandblasting module 20, so as to fix the workpiece on the sandblasting fixture and reduce the shaking of the workpiece during the subsequent sandblasting process; the plug removal and installation mechanism can remove the plug on the workpiece on the sandblasting fixture before the sandblasting fixture enters the unloading area 130, so that the workpiece on the sandblasting fixture can be unloaded smoothly in the unloading area 130.

[0057] Specifically, the plug installation / removal mechanism includes a third actuator and an electromagnet. The third actuator is connected to the electromagnet and can drive the electromagnet to reciprocate between the plug loading area 150 and the plug suction area 160. When energized, the electromagnet can magnetically attract the plug; when de-energized, the electromagnet can release the attracted plug. Furthermore, the third actuator can drive the electromagnet to move to the plug suction area 160, where the electromagnet is energized to attract the plug from the workpiece. Then, the third actuator can drive the electromagnet to move to the plug loading area 150, where the electromagnet is de-energized to install the attracted plug onto the workpiece.

[0058] The following is based on Figure 4 The workpiece transfer method of the second aspect of the present invention will be described.

[0059] According to the workpiece transfer method of the second aspect of the present invention, applied to the transfer module 10 of the first aspect of the present invention, reference is made. Figure 4 The workpiece transfer method of the present invention includes, but is not limited to, the following steps:

[0060] Step S110: Drive the flipping frame 220 to flip to the loading area 110, and clamp the sandblasting fixture located in the loading area 110 through the first clamping component 230;

[0061] Step S120: Drive the flipping frame 220 to flip to the loading area 120 so that the first clamping component 230 drives the sandblasting fixture to be flipped onto the cleaning fixture, and the second clamping component 240 clamps the cleaning fixture located in the loading area 120.

[0062] Step S130: Drive the flipping frame 220 to flip again to the loading area 110 so that the workpiece in the cleaning fixture is transferred to the sandblasting fixture and the first clamping assembly 230 is released from the sandblasting fixture.

[0063] In step S140, the drive flipping frame 220 flips again to the loading area 120, so that the second clamping component 240 drives the cleaning fixture back into the loading area 120 and the second clamping component 240 releases the cleaning fixture.

[0064] It is understood that in the workpiece transfer method of this embodiment, by first inverting the sandblasting fixture onto the cleaning fixture in the loading area 120, and then flipping the sandblasting fixture and the cleaning fixture simultaneously into the loading area 110, the workpiece in the cleaning fixture can be flipped and transferred into the sandblasting fixture while reducing the number of workpieces falling.

[0065] Furthermore, the frame 100 is also provided with a waiting area 130 and a unloading area 140, and the frame 100 is also provided with a first conveyor line 101 and a second conveyor line 102. The first conveyor line 101 passes through the loading area 110 and the waiting area 130, and the second conveyor line 102 passes through the loading area 120 and the unloading area 140. The workpiece transfer method also includes, but is not limited to, the following steps:

[0066] Step S150A: Along the conveying direction of the first conveyor line 101, drive the fully loaded sandblasting fixture in the loading area 110 to leave the loading area 110, and drive the empty sandblasting fixture at the unloading position to enter the loading area 110.

[0067] In step S150B, along the conveying direction of the second conveyor line 102, drive the empty cleaning fixture in the loading area 120 into the unloading area 140, and drive a fully loaded cleaning fixture into the loading area 120.

[0068] It is understandable that the arrangement of the first conveyor line 101 and the second conveyor line 102 allows unloaded sandblasting fixtures to enter the loading area 110 for loading in sequence, and allows fully loaded cleaning fixtures to enter the waiting loading area 120 for workpiece transfer in sequence.

[0069] The following is for reference. Figure 3 The sandblasting equipment of the third aspect of the present invention will be described.

[0070] The sandblasting equipment according to a third aspect of the present invention includes the transfer module 10 of the first aspect of the present invention.

[0071] For details, please refer to Figure 3 The sandblasting equipment includes a sandblasting module 20, the input end of which is connected to the output end of the first conveyor line 101, and the output end of the sandblasting module 20 is connected to the input end of the first conveyor line 101. Furthermore, the transfer module 10 can continuously convey a sandblasting fixture loaded with workpieces to be sandblasted to the sandblasting module 20 for sandblasting, and the transfer module 10 can continuously receive sandblasting fixtures loaded with sandblasted workpieces output from the sandblasting module 20, and unload the sandblasted workpieces from the sandblasting fixtures.

[0072] For details, please refer to Figure 3 The sandblasting module 20 may include a third conveyor line 21 and two sandblasting components 22. The input end of the third conveyor line 21 is connected to the output end of the first conveyor line 101, and the output end of the third conveyor line 21 is connected to the input end of the first conveyor line 101. The third conveyor line 21 passes through the two sandblasting components 22 in sequence.

[0073] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
