[0046] See also Figures 1 to 12 The present embodiment provides a product positioning fixture, which includes a carrier 210, a positioning mechanism and a lifting mechanism 230, wherein the carrier 210 is provided with a profiling groove 211, and the profiling groove 211 is configured to accommodate the product 110. Specifically, the product 110 is pre-installed with a soft flat cable 120, and a release film 130 is attached above the joint area between the product 110 and the flat cable. The product 110, the soft flat cable 120 and the release film 130 are placed together in the profiling groove 211, and the profiling groove 211 can provide a reference for placing the product 110, thereby facilitating the placement of the product 110. The positioning mechanism includes a positioning module 221 and two first positioning pins 2221, and the two first positioning pins 2221 are arranged in the profiling groove 211. The product 110 can be sleeved on the two first positioning pins. The outer periphery of the positioning pin 2221 is used to position the product 110. In addition, the positioning module 221 has a first working state in which the product 110 is pushed against the product 110 and is pressed between the groove wall of the profiling groove 211 and the positioning module 221, and a second working state in which the pushing is released. The positioning module 221 can switch from the second working state to the first working state after the first positioning pin 2221 positions the product 110, thereby fixing the position of the product 110 to prevent the product 110 from shifting during the laser welding process, and the ejecting mechanism 230 is configured to eject the product 110 out of the profiling groove 211, that is, after the welding is completed, the positioning module 221 switches to the second working state, and the ejecting mechanism 230 ejects the product 110, thereby facilitating the removal of the product 110.

[0047] Based on the above, in this embodiment, the profiling groove 211 can provide a reference for placing the product 110, so as to facilitate the placement of the product 110. Moreover, the first positioning pin 2221 provided in the profiling groove 211 can position the product 110, and the positioning module 221 can push the product 110 after the first positioning pin 2221 positions the product 110, so that the product 110 can be pressed and limited between the groove wall of the profiling groove 211 and the positioning module 221, thereby fixing the position of the product 110 to avoid the product 110 from shifting during the laser welding process, thereby avoiding affecting the welding quality. In addition, after the welding is completed, the positioning module 221 releases the pushing, and the ejecting mechanism 230 ejects the product 110, thereby facilitating the removal of the product 110, thereby avoiding affecting the production efficiency.

[0048] It is worth noting that, in the present embodiment, two second positioning pins 2222 are further provided in the contoured groove 211 , and the release film 130 is sleeved on the outer periphery of the two second positioning pins 2222 , so as to further position the product 110 and further ensure the welding quality.

[0049] It can be understood that in other optional embodiments, the number of the first positioning pins 2221 and the second positioning pins 2222 provided in the contoured groove 211 may be three or more, and this embodiment does not impose any specific limitation on this.

[0050] It is also worth mentioning that, in the present embodiment, the positioning module 221 pushes against the parts of the product 110 on both sides of the joining area between the product 110 and the flexible flat cable 120, and abutment blocks 213 are provided on the carrier 210, and the abutment blocks 213 and the carrier 210 together form a contoured groove 211. The positioning module 221 can push against the product 110 and make the product 110 rest against the abutment blocks 213, thereby firmly fixing the product 110.

[0051] In this embodiment, the positioning module 221 includes a first push rod 2211 and an insertion rod 2212. The first push rod 2211 is provided with a first strip hole 22111. The first push rod 2211 is movably installed on the carrier 210 along the extension direction of the first strip hole 22111, and has a first working position in which the product 110 is pushed against the groove wall of the profiling groove 211 and the first push rod 2211, and a second working position in which the push is released. Specifically, the first push rod 2211 is arranged inside the carrier 210, and the first push rod 2211 can be moved along the first strip hole 22111. 22111 moves in the extension direction of the first bar hole 22111, and the insertion rod 2212 is inserted in the first bar hole 22111 and can be moved from the third working position to the profiling groove 211 to the fourth working position along the extension direction of the first bar hole 22111. Specifically, a second bar hole (not shown in the figure) is provided at the bottom of the carrier 210, and the extension direction of the second bar hole is parallel to the extension direction of the first bar hole 22111. The insertion rod 2212 can pass through the second bar hole and be inserted in the first bar hole 22111, and the insertion rod 2212 can move in the first bar hole 22111 and the second bar hole.

[0052] In addition, the positioning module 221 also includes a first elastic member 2213, and the first elastic member 2213 is installed on the side of the first push rod 2211 away from the profiling groove 211 along the extension direction of the first strip hole 22111. Specifically, the first elastic member 2213 abuts between the first push rod 2211 and the carrier 210, wherein the carrier 210 is provided with a stop plate 215, and the first elastic member 2213 abuts between the first push rod 2211 and the stop plate 215. When the insertion rod 2212 is located in the third working position, the insertion rod 2212 abuts against the hole wall of the first strip hole 22111 along its extension direction away from the profiling groove 211, and the first elastic member 2213 is elastically deformed. At this time, the first insertion rod 2212 is located in the second working position. After the insertion rod 2212 moves from the third working position to the fourth working position, the first elastic member 2213 recovers its deformation and is able to drive the first push rod 22 11 moves from the second working position to the first working position toward the side close to the profiling groove 211, that is, when the insertion rod 2212 moves from the third working position to the fourth working position to release the abutment against the hole wall of the first strip hole 22111 along its extension direction away from the profiling groove 211, under the drive of the first elastic member 2213, the first push rod 2211 moves toward the insertion rod 2212 until the insertion rod 2212 moves to the fourth working position, and the first elastic member 2213 drives the first push rod 2211 to stop until the insertion rod 2212 recovers to abut against the hole wall of the first strip hole 22111 along its extension direction away from the profiling groove 211. At this time, the first push rod 2211 moves to the first working position, so that the product 110 can be pushed against the product 110 so that the product 110 is pressed and limited between the groove wall of the profiling groove 211 and the first push rod 2211, so as to fix the position of the product 110.

[0053] As described above, since the first push rod 2211 is moved to a position where it can press against the product 110 by the first elastic member 2213 in this embodiment, the first push rod 2211 is in flexible contact with the product 110 in this embodiment, thereby avoiding damage to the product 110.

[0054] It should be noted that the positioning module 221 in this embodiment includes two first push rods 2211, and the two first push rods 2211 are each correspondingly provided with an insertion rod 2212 and a first elastic member 2213. The two first push rods 2211 can respectively push against the parts of the product 110 on both sides of the joining area between the product 110 and the soft flat cable 120. Moreover, two abutment blocks 213 are provided on the carrier 210, and the two abutment blocks 213 are arranged one by one corresponding to the two first push rods 2211. The positioning module 221 can push against the product 110 and make the product 110 abut against the two abutment blocks 213, thereby more firmly fixing the product 110.

[0055] In addition, the positioning mechanism also includes a moving plate 223, a first rotating shaft 224 and a second push rod 225. The moving plate 223 is slidably connected to the carrier 210 along the extension direction of the first strip hole 22111. Specifically, the moving plate 223 is slidably connected to the bottom of the carrier 210, and the insertion rod 2212 is fixedly connected to the moving plate 223. The second push rod 225 is fixedly connected to the first rotating shaft 224, and the first rotating shaft 224 can rotate around its axis and drive the second push rod 225 to rotate around the axis of the first rotating shaft 224 between the fifth working position and the sixth working position. The moving plate 223 is provided with a first pushing surface 2231 and a second pushing surface 2232, and a blank area 2233 for the second push rod 225 to swing is formed between the first pushing surface 2231 and the second pushing surface 2232. Specifically, an arc surface 2234 is provided between the first pushing surface 2231 and the second pushing surface 2232, thereby forming the blank area 2233. The second push rod 225 can swing in the blank area 2233 driven by the first rotating shaft 224. When the second push rod 225 is moved from the fifth working position to the sixth working position, the second push rod 225 can rotate around the axis of the first rotating shaft 224. When rotating to the sixth working position, the second push rod 225 can push against the first pushing surface 2231 and make the movable plate 223 move forward along the extension direction of the first strip hole 22111, thereby driving the insertion rod 2212 to move from the third working position to the fourth working position. When the second push rod 225 rotates from the sixth working position to the fifth working position, the second push rod 225 can push against the second pushing surface 2232 and make the movable plate 223 move in the opposite direction along the extension direction of the first strip hole 22111, thereby driving the insertion rod 2212 to move from the fourth working position to the third working position. At the same time, the insertion rod 2212 can push the first push rod 2211 to reset from the first working position to the second working position, and the first elastic member 2213 is compressed and deformed.

[0056] Exemplarily, in this embodiment, the first push surface 2231 is perpendicular to the second push surface 2232, and the second push rod 225 can rotate 90° clockwise around the axis of the first rotating shaft 224, thereby rotating from the fifth working position to the sixth working position, and actuating the movable plate 223 to drive the insertion rod 2212 to move from the third working position to the fourth working position. The second push rod 225 can also rotate 90° counterclockwise around the axis of the first rotating shaft 224 to reset, thereby resetting from the sixth working position to the fifth working position, and actuating the movable plate 223 to drive the insertion rod 2212 to reset from the fourth working position to the third working position.

[0057] Of course, in other optional embodiments, the first rotating shaft 224 can also drive the movable plate 223 to move along the extension direction of the first strip hole 22111 through a gear transmission structure or a worm gear transmission structure, and this embodiment does not impose any specific limitation on this.

[0058] Furthermore, the positioning mechanism also includes a handle 226, a first magnet 227 and a second magnet 228. The first rotating shaft 224 is protruded from the carrier 210. The handle 226 is fixedly connected to the first rotating shaft 224 and can rotate around the axis of the first rotating shaft 224, thereby driving the first rotating shaft 224 to rotate around its axis, and then driving the second push rod 225 to rotate. That is, in this embodiment, the staff can control the positioning module 221 to fix the position of the product 110 or release the control of the product 110 through the handle 226. The operation is simple, time-saving and labor-saving, thereby further improving production efficiency.

[0059] The first magnet 227 and the second magnet 228 are respectively located on both sides of the rotation path of the handle 226. When the second push rod 225 rotates to the sixth working position, the handle 226 contacts the first magnet 227. When the second push rod 225 rotates to the fifth working position, the handle 226 contacts the second magnet 228, so that the second push rod 225 can be maintained in the fifth working position or the sixth working position, and then the first push rod 2211 can be in the second working position or the first working position, thereby further ensuring that the positioning module 221 can firmly fix the product 110.

[0060] Based on the content mentioned above, it is worth mentioning that the carrier 210 is provided with two contour grooves 211, all contour grooves 211 are correspondingly provided with positioning modules 221, and all insertion rods 2212 are fixedly connected to the movable plate 223, that is, the present embodiment only provides one movable plate 223, one first rotating shaft 224, one second push rod 225 and one handle 226 to control all positioning modules 221 to simultaneously fix or release the product 110.

[0061] It is understandable that in other optional embodiments, three or more contoured grooves 211 may be provided on the carrier 210, and this embodiment does not impose any specific limitation on this.

[0062] As described above, the product positioning fixture can position more than two products 110 at one time, so that more than two products 110 can be welded at one time later, thereby further improving production efficiency.

[0063] In addition, in the present embodiment, a through hole 212 is provided at the bottom of the contoured groove 211, and the through hole 212 extends in the vertical direction. The ejecting mechanism 230 includes a ejector rod 231, a first mounting plate 232 and a second mounting plate 233. The ejector rod 231 is inserted into the through hole 212 by the bottom of the carrier 210, and the first mounting plate 232 is rotatably connected to the bottom of the carrier 210 through the second rotating shaft 234. Specifically, a mounting block 214 is fixedly connected to the bottom of the carrier 210, and the first mounting plate 232 is rotatably connected to the mounting block 214 through the second rotating shaft 234. The second rotating shaft 234 extends in the horizontal direction, and the ejector rod 231 is fixedly connected to the second mounting plate 233. The second mounting plate 233 is rotatably connected to the first mounting plate 232 through the third rotating shaft 235, and the third rotating shaft 235 is arranged parallel to the second rotating shaft 234.

[0064] From above, the first mounting plate 232 can rotate around the axis of the second rotating shaft 234, so that the second mounting plate 233 can be lifted and lowered in the vertical direction. When the second mounting plate 233 rises in the vertical direction, the push rod 231 can extend into the profiling groove 211, so as to push the product 110 out of the profiling groove 211. After the second mounting plate 233 descends in the vertical direction, the push rod 231 can be retracted into the through hole 212, so that the product 110 can be placed in the profiling groove 211.

[0065] Furthermore, the ejection mechanism 230 also includes a pressing head 236 and a second elastic member 237. The pressing head 236 is protruded from the carrier 210 in the vertical direction and is rotatably connected to the first mounting plate 232 through a fourth rotating shaft 238. The fourth rotating shaft 238 is arranged in parallel with the second rotating shaft 234. The fourth rotating shaft 238 and the third rotating shaft 235 are respectively located on both sides of the second rotating shaft 234 in a direction perpendicular to its axial direction. The pressing head 236 can move in the vertical direction, and the second elastic member 237 is arranged between the carrier 210 and the second mounting plate 233. Specifically, a mounting column 2331 is arranged on the second mounting plate 233, and the mounting column 2331 is inserted into the carrier 210. 0, and can move relative to the carrier 210 in the vertical direction. The second elastic member 237 is sleeved on the outer periphery of the mounting column 2331 and abuts between the carrier 210 and the second mounting plate 233. The staff can press the pressure head 236 to rotate the first mounting plate 232 around the axis of the second rotating shaft 234 and drive the second mounting plate 233 to rise in the vertical direction. At the same time, the second elastic member 237 is compressed and deformed. After the product 110 is taken away, the staff releases the pressure head 236, and then the second elastic member 237 recovers the deformation, so that the second mounting plate 233 descends in the vertical direction to retract the top rod 231 into the through hole 212.

[0066] That is, in this embodiment, the staff can control the push rod 231 to push out the product 110 or retract the push rod 231 into the perforation 212 through the pressure head 236, which is easy to operate, saves time and effort, and can further improve production efficiency.

[0067] It should also be noted that the carrier 210 is fixedly mounted on the base 216, and the bottom of the carrier 210 is fixedly connected to a guide column 217, which extends in the vertical direction. The second mounting plate 233 is sleeved on the outer periphery of the guide column 217, and the guide column 217 can provide a guiding effect for the movement of the second mounting plate 233, thereby ensuring that the second mounting plate 233 can be accurately lifted and lowered in the vertical direction.

[0068] Based on the above, the carrier 210 is provided with two contour grooves 211. It should also be noted that all contour grooves 211 are correspondingly provided with ejector rods 231, and all ejector rods 231 are fixedly connected to the same second mounting plate 233, that is, the present embodiment can control the ejection of all products 110 at the same time by only one pressing head 236, thereby further improving production efficiency.

[0069] In addition, the product positioning fixture also includes a pressing claw 241, a third magnet 242 and a fourth magnet 243. The pressing claw 241 is rotatably connected to the carrier 210 via a fifth rotating shaft 244, and has a seventh working position for pressing the product 110, and an eighth working position for releasing the pressing. When the pressing claw 241 is located at the seventh working position, the pressing claw 241 contacts the third magnet 242, so that the pressing claw 241 can maintain pressing the product 110, thereby further ensuring that the product 110 will not shift during the welding process. When the pressing claw 241 is located at the eighth working position, the pressing claw 241 contacts the fourth magnet 243, thereby keeping the pressing claw 241 at the eighth working position, thereby facilitating the placement of the product 110.

[0070] As described above, in this embodiment, the pressing claw 241 includes three claw portions 2411, and the three claw portions 2411 are arranged at intervals along the axial direction of the fifth rotating shaft 244, so as to ensure that the pressing claw 241 can more effectively press the product 110, thereby further ensuring that the product 110 will not shift during the welding process.

[0071] Based on the above-mentioned contents, the carrier 210 is provided with two profiling grooves 211 . It should also be noted that all the profiling grooves 211 are correspondingly provided with pressing claws 241 .

[0072] Furthermore, the three claws 2411 are fixedly connected by the connecting rod 2412, thereby ensuring that the three claws 2411 can synchronously rotate around the axis of the fifth rotating shaft 244, thereby ensuring that the pressing claw 241 can press the product 110 more effectively and stably.

[0073] It is understandable that in other optional embodiments, the pressing claw 241 may also include two or more than four claw portions 2411 , and this embodiment does not impose any specific limitation on this.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
