[0028] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0029] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0030] like Figure 1 and Figure 2As shown, a screw locking device according to a preferred embodiment of the present invention includes: a workbench 100, a fixture 200, a first clamping assembly 300, a driving device 400, a locking device 500, a robot 600, a second clamping assembly 700 and a loading device 800.

[0031] The jig 200 is placed on a workbench 100. The first clamping assembly 300 is used to clamp the pressing assembly 220. The driving device 400 is rotatably mounted on the workbench 100 and is used to drive the first clamping assembly 300 to rotate. The locking device 500 is used to lock the driving device 400 when the pressing assembly 220 is pressing the material.

[0032] A robot 600 is mounted on the workbench 100 and is used to tighten screws on the material. In this embodiment, two robots 600 are provided and mounted on the workbench 100 frame above the workbench 100 support platform. A second clamping assembly 700 is mounted on the press assembly 220 and is used to clamp the material. A feeder for providing screws is also mounted on the workbench 100 support platform.

[0033] like Figure 3 As shown, the fixture 200 includes a material loading component 210 for placing the material and a material pressing component 220 for pressing the material.

[0034] like Figure 3 and Figure 4 As shown, the material loading assembly 210 includes a base plate 211 and a plurality of support blocks 212 mounted on the base plate 211. Each support block 212 is provided with a contoured groove that conforms to the shape of the material to support it. The support blocks 212 can be replaced according to the shape of the material. The number of support blocks 212 can be selected based on the area of ​​the material.

[0035] A vertically extending retaining groove 2111 is defined on one sidewall of the base plate 211. The number of retaining grooves 2111 can be adjusted as needed. In this embodiment, two retaining grooves 2111 are provided. A positioning hole 2112 is defined on the base plate 211, located on the side of the base plate 211 opposite the retaining groove 2111. Two sets of handles 2113 are provided on the base plate 211, one on each side of the base plate 211 opposite the retaining groove 2111 and the positioning hole 2112. Each set of handles 2113 contains two handles.

[0036] like Figure 3 and Figure 5As shown, the material pressing assembly 220 includes a top plate 221 and a pressing member 222 mounted on the top plate 221 to press the material. The top plate 221 is hollowed out, and the hollowing out of the top plate 221 provides multiple through-holes, thereby reducing the weight of the top plate 221 and facilitating the installation of the pressing member 222. The pressing member 222 is cylindrical, and there are multiple pressing members 222. The number and arrangement of the pressing members 222 can be set according to the shape of the material and the location on the material where pressure is required.

[0037] Fixed blocks 223 are mounted on both sides of the top plate 221. Grooves 2231 are formed on the sidewalls of the fixed blocks 223, extending vertically through the fixed blocks 223. In this embodiment, two fixed blocks 23 are provided on each sidewall of the top plate 221, with the grooves 231 located on the outermost walls of the fixed blocks 23. The fixed blocks 223 and the handle 2113 are located on the same side. In other embodiments, the number of fixed blocks 23 can be selected as needed, and can be one or three or more.

[0038] Combine Figure 3 、 Figure 4 and Figure 5 As shown, a positioning assembly is provided between the material loading assembly 210 and the material pressing assembly 220. The positioning assembly includes a first positioning member 2114 mounted on the bottom plate 211 and a second positioning member 2211 mounted on the top plate 221. A positioning groove 21141 is provided on the first positioning member 2114, and a positioning protrusion 22111 is provided on the second positioning member 2211. When the pressing member 222 presses and fixes the material placed on the support block 212, the positioning protrusion 22111 simultaneously enters the positioning groove 21141 to achieve positioning between the material loading assembly 210 and the material pressing assembly 220, ensuring precise pressing and fixation. In other embodiments, a positioning protrusion can also be provided on the first positioning member 2114, and a positioning groove can be provided on the second positioning member 2211.

[0039] like Figure 6 and Figure 7 As shown, the first clamping assembly 300 is mounted on the drive device 400. In this embodiment, two sets of the first clamping assembly 300 are provided to clamp the fixed blocks 223 on both sides of the top plate 221. Specifically, the first clamping assembly 300 includes a mounting plate 301, a first cylinder 302, and a pressure block 303. In this embodiment, the first cylinder 302 and the pressure block 303 form a set, and two sets are provided to clamp the two fixed blocks 223 on one side of the top plate 221.

[0040] Furthermore, the mounting plate 301 is installed in cooperation with the driving device 400, the cylinder body of the first cylinder 302 is fixedly installed on the mounting plate 301, the pressing block 303 is fixedly installed on the telescopic rod of the first cylinder 302, and the first cylinder 302 drives the pressing block 303 to move to cooperate with the mounting plate 301 to clamp or release the pressing assembly 220.

[0041] like Figure 7 As shown, the pressing block 303 is formed with a first protrusion 3031 located at the bottom of the pressing block 303, and two receiving grooves are formed between the two sides of the first protrusion 3031 and the pressing block 303. When the pressing block 303 is driven downward by the first cylinder 302, the first protrusion 3031 is inserted into the groove 2231 on the fixed block 223, thereby cooperating with the mounting plate 301 to clamp the fixed block 223 of the pressing assembly 220. In other embodiments, the first protrusion 3031 and the groove 2231 may not be provided.

[0042] In this embodiment, a guide rod 304 is mounted on the mounting plate 301, and a guide bearing 305 is installed between the guide rod 304 and the drive device 400. Specifically, one end of the guide rod 304 is fixedly mounted to the mounting plate 301, and the other end passes through the drive device 400, with the guide bearing 305 disposed between the guide rod 304 and the drive device 400. The mounting plate 301 is mounted in conjunction with the cylinder body of the second cylinder 306, and the telescopic shaft of the second cylinder 306 is mounted in conjunction with the drive device 400. The second cylinder 306 can drive the mounting plate 301 up and down. When the first cylinder 302 drives the pressing block 303 downward to cooperate with the mounting plate 301 to clamp the fixed block 223 of the material pressing assembly 220, the second cylinder 306 then drives the mounting plate 301 down, thereby driving the material pressing assembly 220 down to compact the material, thereby improving the degree of compaction.

[0043] like Figure 6 As shown, the driving device 400 includes a bracket 410 and a third cylinder 420 , the cylinder body of the third cylinder 420 is rotatably mounted on the workbench 100 , the telescopic rod of the third cylinder 420 is rotatably mounted on the bracket 410 , and the bracket 410 is rotatably mounted on the workbench 100 .

[0044] The bracket 410 includes two first connecting rods 411 arranged in parallel and a third connecting rod 412 connecting the first connecting rods 411. The number of the first connecting rods 411 and the third connecting rod 412 can be selected according to needs. In other embodiments, the bracket 410 can also be of other structures. A base 430 is installed on the support platform of the workbench 100. There are two bases 430 to match the first connecting rods 411. One end of the two first connecting rods 411 of the bracket 410 is rotatably installed with the corresponding base 430 through the corresponding first rotating shaft 440. In this embodiment, combined with Figure 6 and Figure 7The telescopic shaft of the second cylinder 306 is fixedly installed with the first connecting rod 411 , and a guide bearing 305 is provided between the guide rod 304 and the first connecting rod 411 .

[0045] In this embodiment, a limit block 450 is mounted on the base 430. The limit block 450 can be tilted or processed to produce an inclined surface 451. The limit block 450 can be used to limit the rotation angle of the bracket 410 based on the inclined surface 451. For example, when the first connecting rod 411 rotates clockwise with the first rotating shaft 440 as the fulcrum, the end surface of the first connecting rod 411, which was originally perpendicular to the horizontal plane, also tilts due to the rotation. When the end surface of the first connecting rod 411 tilts due to the rotation and contacts the inclined surface 451 of the limit block 450, the first connecting rod 411 cannot continue to rotate, thereby achieving a limiting effect. In other embodiments, the limit block 450 can also be limited by the inclined surface.

[0046] Two third cylinders 420 are provided corresponding to the two first connecting rods 411. The cylinder body of the third cylinder 420 is rotatably mounted to the workbench 100, and the telescopic rod of the third cylinder 420 is rotatably mounted to the bracket 410. Specifically, the cylinder body of the third cylinder 420 is rotatably mounted to the mounting bracket 110 of the workbench 100. Based on this, since the cylinder body of the third cylinder 420 is rotatably mounted to the workbench 100 and the telescopic rod of the third cylinder 420 is rotatably mounted to the bracket 410, the third cylinder 420 can effectively push the bracket 410 and cause the bracket 410 to rotate about the first rotating shaft 440.

[0047] Furthermore, a fixing member is mounted on the cylinder body of the third cylinder 420, on which a second rotating shaft is mounted. The second rotating shaft is mounted in conjunction with a bearing and a bearing seat via a bearing, and the bearing seat is fixedly mounted to the mounting bracket 110 of the workbench 100. The telescopic rod of the third cylinder 420 is rotatably mounted to the bracket 410 via a fisheye bearing 460. Specifically, a third rotating shaft 414 is mounted on the first connecting rod 411, and the third rotating shaft 414 is rotatably mounted to the telescopic rod of the third cylinder 420 via the fisheye bearing 460.

[0048] like Figure 6 As shown, the locking device 500 includes a fifth cylinder 510 , and a locking hole is provided on the driving device 400 . The telescopic shaft of the fifth cylinder 510 can be inserted into the locking hole to lock the driving device 400 .

[0049] Specifically, the bracket 410 further includes two third connecting rods 413 connected to the first connecting rod 411. The third connecting rods 413 are vertically arranged, one end of the third connecting rod 413 is connected to the first connecting rod 411, and the other end has a locking hole. The third connecting rod 413 and the first rotating shaft 440 are located at both ends of the first connecting rod 411.

[0050] In this embodiment, the third cylinder 420 rotates and lifts the bracket 410, and the first cylinder 302 drives the pressing block 303 to cooperate with the mounting plate 301 to clamp the material pressing assembly 220. The third cylinder 420 then rotates and lowers the bracket 410, so that the end of the first connecting rod 411 is inserted into the mounting groove 120. The mounting groove 120 is provided below the support platform of the workbench 100. The fifth cylinder 510 drives its telescopic shaft to insert into the locking hole of the third connecting rod 413 to lock the bracket 410. The second cylinder 306 drives the mounting plate 301 downward, so that the pressing member 222 presses and compacts the material on the support block 212.

[0051] like Figure 3 As shown, there are two sets of second clamping assemblies 700. In this embodiment, the two sets of second clamping assemblies 700 are symmetrically mounted on the top plate 221.

[0052] like Figure 8 As shown, the second clamping assembly 700 includes a connecting member 710 , a material clamping member 720 , a fourth cylinder 730 and a push-pull member 740 .

[0053] Specifically, the connecting member 710 is rotatably mounted on the pressing assembly 220. Furthermore, the connecting member 710 is vertically arranged, and a connecting block 750 is installed on the top plate 221. The connecting member 710 is rotatably mounted with the connecting block 750 via a first connecting shaft 760. The first connecting shaft 760 passes through the connecting block 750 and the connecting member 710 at the same time. The first connecting shaft 760 is arranged near the top of the connecting member 710, and two connecting blocks 750 are provided and are respectively located on both sides of the connecting member 710.

[0054] The clamping member 720 is installed on the connecting member 710 . Specifically, the clamping member 720 is installed at the lower end of the connecting member 710 . The clamping members 720 of the two groups of second clamping assemblies 700 are arranged opposite to each other.

[0055] The push-pull member 740 is mounted in conjunction with the fourth cylinder 730 and includes a first connecting portion 741, a second connecting portion 742, and a third connecting portion 743. The first connecting portion 741 is fixedly mounted to the telescopic shaft of the fourth cylinder 730, and the cylinder body of the fourth cylinder 730 is mounted on the top plate 221. The second connecting portion 742 and the third connecting portion 743 are arranged parallel to each other, with one end each mounted on the first connecting portion 741. The first, second, and third connecting portions 741, 742, 743 are integrally formed. The top portion of the connector 710 can be inserted between the second and third connecting portions 742, 743.

[0056] A second connecting shaft 770 is mounted on the push-pull member 740 and passes through both the second connecting portion 742 and the third connecting portion 743. A slot 711 is defined on the connecting member 710. The slot 711 extends vertically downward from the top of the connecting member 710 and extends through both sides of the connecting member 710. This ensures that the second connecting shaft 770 can enter the slot 711 when the top of the connecting member 710 is inserted between the second connecting portion 742 and the third connecting portion 743.

[0057] Driven by the fourth cylinder 730, the push-pull member 740 pushes and pulls the connecting member 710 via the second connecting shaft 770 and the retaining slot 711. The two clamping members 720, driven by the corresponding connecting member 710, clamp and release the material. When the push-pull member 740 pushes the connecting member 710, the two clamping members 720 clamp the material. When the push-pull member 740 pulls the connecting member 710, the two clamping members 720 release the material.

[0058] like Figure 9 and Figure 10 As shown, the loading device 800 includes a support frame 810 for placing the jig 200 and a blocking and locking assembly mounted on the support frame 810. A locking groove 130 is formed on the workbench 100. The blocking and locking assembly is used to block the jig 200 and interlock with the workbench 100 in conjunction with the locking groove 130. In this embodiment, two sets of blocking and locking assemblies are provided.

[0059] like Figure 10 As shown, the locking groove 130 is formed by a mounting block 140 fixedly mounted on one side wall of the workbench 100 and enclosed by the side wall of the workbench 100. A first groove body and a second groove body are respectively formed on the side wall of the mounting block 140 close to the workbench 100 and the side wall away from the workbench 100. The first groove body and the second groove body are interconnected and can both penetrate the top of the mounting block 140. The projected area of ​​the first groove body on the side wall of the workbench 100 is smaller than the projected area of ​​the second groove body on the side wall of the workbench 100. That is, the lower end of the second groove body has a blocking portion 141 near the side of the first groove body. The blocking portion 141 also serves as the bottom of the first groove body. The locking groove 130 is formed by the first groove body, the second groove body, the blocking portion 141, and the side wall of the workbench 100.

[0060] like Figure 9 and Figure 10As shown, the blocking and locking assembly includes a connecting rod 821, a locking block 822, and a blocking block 823. The connecting rod 821 is rotatably mounted on the support frame 810, the blocking block 823 is fixedly mounted on the connecting rod 821, and the locking block 822 is fixedly mounted on the end of the connecting rod 821. The locking block 822 has a protrusion 8221 formed on it. The blocking block 823 is used to block the fixture 200 placed on the support frame 810 and release the blockage as the connecting rod 821 rotates. The protrusion 8221 rotates into the locking groove 130 as the connecting rod 821 rotates to lock the loading device 800 and the workbench 100 to each other.

[0061] The locking block 822 and the protrusion 8221 are inserted through the first groove into the upper end of the second groove. The connecting rod 821 is rotated to rotate the locking block 822 and the protrusion 8221. When the protrusion 8221 is rotated and inserted into the lower end of the second groove, the protrusion 8221 is blocked by the blocking portion 141, thereby locking the loading device 800 with the workbench 100. At the same time, when the jig 200 is placed on the support frame 810, the connecting rod 821 is rotated to rotate the blocking block 823 and block the jig 200, thereby preventing the jig 200 from falling during transportation. When the jig 200 needs to be moved, the connecting rod 821 is rotated again to rotate the blocking block 823 to release the blocking of the jig 200.

[0062] like Figure 9 As shown, the support frame 810 is provided with two sets of first guide wheel assemblies and two sets of first bull's eye wheel assemblies to facilitate the movement of the jig 200. Each set of first guide wheel assemblies is composed of a plurality of first guide wheels 910 arranged in a row, and each set of first bull's eye wheel assemblies is composed of a plurality of first bull's eye wheels 1010 arranged in a row. The two sets of first guide wheel assemblies are respectively located outside the two sets of blocking and locking assemblies, and the two sets of first bull's eye wheel assemblies are respectively located inside the blocking and locking assemblies. The first guide wheels 910 abut against the side walls of the base plate 211 of the jig 200, and the first bull's eye wheels 1010 abut against the bottom of the base plate 211 of the jig 200. The provision of the first guide wheel assemblies and the first bull's eye wheel assemblies facilitates the movement of the jig 200 onto the workbench 100.

[0063] In addition, Figure 6 As shown, two sets of second guide wheel assemblies and two sets of second bull's-eye wheel assemblies are installed on the support platform of the workbench 100 to facilitate the movement of the jig 200. Each set of second guide wheel assemblies consists of a plurality of second guide wheels 2010 arranged in a row, and each set of second bull's-eye wheel assemblies consists of a plurality of second bull's-eye wheels 3010 arranged in a row. A row of second guide wheels 2010 is arranged corresponding to a row of first guide wheels 910, and a row of second bull's-eye wheels 3010 is arranged corresponding to a row of first bull's-eye wheels 1010. The two sets of second bull's-eye wheel assemblies are located between the two sets of second guide wheel assemblies.

[0064] like Figure 6As shown, two sets of third bull's eye wheel assemblies 4000 are installed on the workbench 100 located between the two sets of first clamping assemblies 300, and the two sets of third bull's eye wheel assemblies are also located between the corresponding two sets of second guide wheel assemblies.

[0065] like Figure 11 As shown, the third bull's eye wheel assembly 4000 includes a lifting plate 4001 , a third bull's eye wheel 4002 , a sixth cylinder 4003 , a guide shaft 4004 and a sleeve 4005 .

[0066] Combine Figure 11 and Figure 6 Multiple third bull's-eye wheels 4002 are provided and mounted on the lifting plate 4001. These third bull's-eye wheels 4002 are arranged with corresponding second bull's-eye wheels 3010. The third bull's-eye wheels 4002 of the two third bull's-eye wheel assemblies and the second bull's-eye wheels 3010 of the two second bull's-eye wheel assemblies are arranged in two rows. One end of the guide shaft 4004 is fixedly mounted to the bottom of the support platform of the workbench 100. The other end of the guide shaft 4004 passes through the lifting plate 4001, with a shaft sleeve 4005 disposed between the guide shaft and the lifting plate 4001. The cylinder body of the sixth cylinder 4003 is fixedly mounted to the lifting plate 4001, and the telescopic shaft of the sixth cylinder 4003 is fixedly mounted to the bottom of the support platform of the workbench 100. A through hole is provided on the support platform of the workbench 100 for the third bull's eye wheel 4002 to extend out. The sixth cylinder 4003 drives the lifting plate 4001 to rise and fall, so that the third bull's eye wheel 4002 can be lifted from the bottom of the support platform of the workbench 100 through the support platform.

[0067] like Figure 6 and Figure 4 As shown, the support platform of the workbench 100 is also equipped with a positioning column 101 and a positioning block 102. The jig 200 is moved so that the positioning column 101 is inserted into the retaining groove 2111 of the base plate 211 for positioning, while the side wall of the base plate 211 abuts the positioning block 102. Furthermore, a seventh cylinder is installed at the bottom of the support platform of the workbench 100. This seventh cylinder extends its telescopic shaft through the support platform of the workbench 100 and inserts it into the positioning hole 2112 of the base plate 211 for repositioning.

[0068] Combine Figures 1 to 11 , the working principle of this embodiment is:

[0069] The loading assembly 210 on which the material with unclocked screws is placed is placed on the support frame 810 of the loading device 800. The loading assembly 210 is pushed onto the workbench 100 very effortlessly by the first guide wheel 910 and the first bull's eye wheel 1010, the second guide wheel 2010 and the second bull's eye wheel 3010, and the third bull's eye wheel 4002. Finally, the loading assembly 210 is pushed until the positioning column 101 is inserted into the limiting groove 2111 of the base plate 211, and the side wall of the base plate 211 abuts against the positioning block 102. At this time, the sixth cylinder 4003 drives the third bull's eye wheel 4002 to descend, so that the loading assembly 210 is placed stably on the support platform of the workbench 100, and the seventh cylinder extends its telescopic shaft and inserts it into the positioning hole 2112 of the base plate 211. At this point, the positioning of the loading assembly 210 on which the material to be processed is placed is completed.

[0070] The third cylinder 420 drives the bracket 410 to rotate and descend, allowing the third connecting rod 413 to extend into the mounting slot 120. At this point, the fifth cylinder 510 drives its telescopic shaft into the locking hole, thereby locking the bracket 410. Simultaneously, as the third cylinder 420 drives the bracket 410 to rotate and descend, the first clamping assembly 300 also drives the pressing assembly 220 to rotate and descend, allowing the pressing member 222 to press the material. The robot 600 then secures the material with screws.

[0071] After the screws are tightened, the fourth cylinder 730 pushes the connector 710, and the two clamps 720 clamp the material. The fifth cylinder 510 withdraws its telescopic shaft from the locking hole, and the third cylinder 420 rotates and raises the bracket 410, thereby rotating and raising the material to facilitate its removal. Simultaneously, the empty loading assembly 210 is moved to the support frame 810 of the loading device 800 to replace the unscrewed material.
