[0030] Reference below Figure 1 and Figure 2 The transfer module 10 of the first aspect of the present invention is described in detail.

[0031] Reference Figure 1 According to the first aspect of the utility model, the transfer module 10 includes a frame 100 and a flip mechanism 200.

[0032] A loading area 110 and a waiting area 120 are provided on the frame 100. The loading area 110 is used to store sandblasting jigs, and the waiting area 120 is used to store cleaning jigs. The flipping mechanism 200 is provided on the frame 100 and is located between the loading area 110 and the waiting area 120. The flipping mechanism 200 includes a driving component 210, a flipping frame 220, a first clamping component 230 and a second clamping component 240. The first clamping component 230 and the second clamping component 240 are both provided on the flipping frame 220, and the driving component 210 is connected to the flipping frame 220.

[0033] For example, Figure 1 and Figure 2 As shown, a loading area 110 and a waiting area 120 for loading are provided on the frame 100, and the loading area 110 is located at the front side of the waiting area 120 for loading; a flip mechanism 200 is provided between the loading area 110 and the waiting area 120 for loading, and the flip mechanism 200 includes a driving assembly 210, a flip frame 220, a first clamping assembly 230 and a second clamping assembly 240, and an edge of the flip frame 220 is hinged between the loading area 110 and the waiting area 120 for loading, and the driving assembly 210 is connected to the flip frame 220. Under the drive of the driving assembly 210, the flip frame 220 can flip forward and backward to move the flip frame 220 into the loading area 110.

[0034] Or, so that the flip frame 220 moves to the loading area 120, the first clamping assembly 230 and the second clamping assembly 240 are both arranged on the flip frame 220, when the flip frame 220 is flipped to the loading area 110, the first clamping assembly 230 is located below the second clamping assembly 240, and when the flip frame 220 is flipped to the loading area 120, the second clamping assembly 240 is located below the first clamping assembly 230.

[0035] It can be understood that when the transfer module 10 of the present invention is working, an empty sandblasting jig can be placed in the loading area 110, and a cleaning jig fully loaded with workpieces can be placed in the waiting loading area 120. Under the drive of the driving component 210, the flip frame 220 can flip forward to move the flip frame 220 into the loading area 110. At this time, the first clamping component 230 can clamp the sandblasting jig in the loading area 110; then, the driving component 210 can drive the flip frame 220 to flip backward to flip the flip frame 220 into the waiting loading area 120. At this time, the sandblasting jig can be inverted on the cleaning jig and Furthermore, the second clamping assembly 240 can clamp the cleaning jig; then, the driving assembly 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 jig can be inverted into the sandblasting jig to achieve the transfer of the workpiece from the cleaning jig to the sandblasting jig, and the workpiece can be turned over when transferred to the sandblasting jig; then, the first clamping assembly 230 releases the sandblasting jig, and the driving assembly 210 drives the flipping frame 220 to flip backward to move the unloaded cleaning jig back to the loading area 120; then, the second clamping assembly 240 releases the cleaning jig. Furthermore, in the transfer module 10 of the present embodiment, the transfer module 10 can automatically flip the workpiece in the cleaning jig and transfer it to the sandblasting jig, reducing the workload of the staff and saving time and effort.

[0036] It can be understood that since the first clamping assembly 230 and the second clamping assembly 240 are simultaneously provided on the flip frame 220, and when the transfer module 10 is working, there is a situation where the first clamping assembly 230 clamps the sandblasting jig while the second clamping assembly 240 also clamps the cleaning jig. In this case, it is necessary to avoid mutual interference between the sandblasting jig and the cleaning jig.

[0037] In view of the above problems, in a further embodiment of the present utility model, reference is made to Figure 2 The first clamping assembly 230 includes a first driver 231 and a plurality of first clamping structures 232, and the plurality of first clamping structures 232 surround and form a first accommodating cavity for accommodating a sandblasting jig. The first driver 231 is connected to each of the first clamping structures 232 and is used to drive the first clamping structure 232 to move closer to or away from the first accommodating cavity. The second clamping assembly 240 includes a second driver 241 and a plurality of second clamping structures 242, and the plurality of second clamping structures 242 surround and form a second accommodating cavity for accommodating a cleaning jig. The second driver 241 is connected to each of the second clamping structures 242 and is used to drive the second clamping structure 242 to move closer to or away from the second accommodating cavity. The second accommodating cavity is located on one side of the first accommodating cavity and is connected to the first accommodating cavity.

[0038] It can be understood that since the multiple first clamping structures 232 are surrounded to form the first accommodating cavity, and the multiple second clamping structures 242 are surrounded to form the second accommodating cavity, when the first clamping assembly 230 clamps the sandblasting jig, and the second clamping assembly 240 clamps the cleaning jig, the sandblasting jig can be accommodated in the first accommodating cavity, and the cleaning jig can be accommodated in the second accommodating cavity, and the sandblasting jig and the cleaning jig do not interfere with each other; at the same time, since the first accommodating cavity and the second accommodating cavity are connected, the workpiece in the cleaning jig can enter the sandblasting jig normally.

[0039] For example, when the flip frame 220 flips into the loading area 120, the first accommodating cavity can be located above the second accommodating cavity; when the flip frame 220 flips into the loading area 110, the first accommodating cavity can be located below the second accommodating cavity.

[0040] Specifically, refer to Figure 2 Here, the first clamping assembly 230 is described in detail when the flip 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 flip frame 220 are each provided with two locking members. The first driver 231 includes four first cylinders. The four first cylinders correspond to and are connected to the four locking members one by one. The first cylinder can drive the locking member connected thereto to approach or move away from the first accommodating cavity to clamp or release the sandblasting jig in the first accommodating cavity.

[0041] Specifically, refer to Figure 2 Here, the second clamping assembly 240 is described in detail when the flip frame 220 is 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 respectively located on the edges of the flip frame 220 on the left and right sides, and the second clamping structures 242 are slidably arranged along the left and right directions, the second driver 241 includes two second cylinders, the two second cylinders are respectively connected to the two second clamping structures 242, and the second cylinders can drive the second clamping structures 242 connected thereto to move left and right to approach or move away from the second accommodating cavity; the second clamping structure 242 includes a thumb cylinder 242a and a clamping claw 242b, the thumb cylinder 242a is connected to the clamping claw 242b, and under the drive of the thumb cylinder 242a, the clamping claw 242b can clamp or release the edge of the cleaning jig located in the second accommodating area.

[0042] It is understandable that after the workpiece in the cleaning jig is transferred to the sandblasting jig, if the empty cleaning jig in the loading area 120 is replaced manually, or the fully loaded sandblasting jig in the loading area 110 is replaced manually, the labor cost will undoubtedly be greatly increased.

[0043] In order to reduce labor costs, refer to Figure 1 In some embodiments of the utility model, a material unloading area 130 and a material unloading area 140 are further provided on the frame 100. The material unloading area 130 is located on the right side of the loading area 110, and the material unloading area 140 is located on the right side of the material unloading area 120. The frame 100 is also provided with a first conveyor line 101 for conveying sandblasting jigs and a second conveyor line 102 for conveying cleaning jigs. The first conveyor line 101 extends in the left-right direction and passes through the loading area 110 and the material unloading area 130. The first conveyor line 101 can convey the sandblasting jig from right to left. The second conveyor line 102 extends in the left-right direction and passes through the material unloading area 120 and the material unloading area 140. The second conveyor line 102 can convey the cleaning jig from left to right. Furthermore, when the sandblasting jig in the loading area 110 is fully loaded, the fully loaded sandblasting jig can be conveyed to the left along the first conveyor line 101 to leave the loading area 110, and then, another empty sandblasting jig that has unloaded the workpiece in the unloading area 130 can be conveyed to the loading area 110 along the first conveyor line 101 to wait for loading of the workpiece; when the cleaning jig in the loading area 120 is empty, the empty cleaning jig can be conveyed to the right along the second conveyor line 102 to the unloading area 140 to receive the workpiece unloaded from the sandblasting jig in the unloading area 130, and then, another fully loaded cleaning jig can be conveyed to the right along the second conveyor line 102 to the loading area 120.

[0044] For further reference, Figure 1The transfer module 10 further includes a transport mechanism 300 , which is disposed on the frame 100 and is used to transport the workpiece on the sandblasting fixture in the unloading area 130 to the cleaning fixture in the unloading area 140 .

[0045] It can be 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 jig output by the sandblasting module 20 can be conveyed to the unloading position along the first conveyor line 101, and then the conveying mechanism 300 conveys the workpiece on the sandblasting jig at the unloading position to the cleaning jig at the unloading position, and then the unloaded sandblasting jig can be conveyed to the loading position along the first conveyor line 101 to wait for loading of workpieces. After the workpiece is loaded at the loading position, the sandblasting jig can be conveyed to the input end of the sandblasting module 20 along the first conveyor line 101; after the workpiece in the cleaning jig at the loading position is transferred to the sandblasting jig, the unloaded cleaning jig can be conveyed to the unloading position along the second conveyor line 102, and receive the workpiece conveyed by the conveying mechanism 300 from the fully loaded sandblasting jig at the unloading position.

[0046] For further reference, Figure 1 In a further embodiment of the utility model, the transfer module 10 also includes a plug disassembly and assembly mechanism (not shown in the figure), which is arranged on the frame 100. The frame 100 is also provided with a plug installing area 150 and a plug suction area 160, both of which are located on the first conveyor line 101. Along the conveying direction of the first conveyor line 101, the plug installing area 150 is located on the rear side of the loading area 110, and the plug suction area 160 is located on the front side of the unloading area 130. The plug disassembly and assembly mechanism is used to remove the plug in the sandblasting jig located in the plug suction area 160, and install the plug on the sandblasting jig located in the plug installing area 150.

[0047] It can be understood that by setting up a plug disassembly and assembly mechanism, the plug disassembly and assembly mechanism can install the plug on the workpiece of the sandblasting jig before the sandblasting jig enters the sandblasting module 20 to fix the workpiece on the sandblasting jig, thereby reducing the shaking of the subsequent workpiece during the sandblasting process; the plug disassembly and assembly mechanism can remove the plug on the workpiece on the sandblasting jig before the sandblasting jig enters the waiting area 130, so that the workpiece on the sandblasting jig can be smoothly unloaded in the waiting area 130.

[0048] Specifically, the plug disassembly and assembly mechanism includes a third driver and an electromagnet. The third driver is connected to the electromagnet and can drive the electromagnet to move back and forth between the plug installation area 150 and the plug suction area 160. The electromagnet can magnetically absorb the plug when it is powered on, and can release the absorbed plug when it is powered off. Then, the third driver can drive the electromagnet to move to the plug suction area 160, and the electromagnet is powered on to absorb the plug on the workpiece, and then the third driver can drive the electromagnet to move to the plug installation area 150, and the electromagnet is powered off to install the absorbed plug on the workpiece.

[0049] Reference below Figure 3 The sandblasting equipment according to the second aspect of the present invention will be described.

[0050] The sandblasting equipment according to the second embodiment of the utility model includes the transfer module 10 according to the first embodiment of the utility model.

[0051] Specifically, refer to Figure 3 The sandblasting equipment includes a sandblasting module 20, the input end of the sandblasting module 20 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 transport the sandblasting jig loaded with the workpiece to be sandblasted to the sandblasting module 20 for sandblasting, and the transfer module 10 can continuously receive the sandblasting jig loaded with the workpiece that has been sandblasted output by the sandblasting module 20, and unload the workpiece that has been sandblasted on the sandblasting jig.

[0052] Specifically, refer to Figure 3 The sandblasting module 20 may include a third conveyor line 21 and two sandblasting assemblies 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 assemblies 22 in sequence.

[0053] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
