[0025] Referring to Figures 1-7 , a heat dissipation fin detection tooling, comprising a frame body 1. A conveying tooling assembly 4 is provided at the top of the frame body 1. A plurality of mounting tooling assemblies 5 for adaptively adjusting and fixing heat dissipation fins of different lengths are provided on the conveying tooling assembly 4. A lower detection tooling assembly 3 for detecting the downward bending of the deformation degree of the heat dissipation fins placed in the mounting tooling assembly 5 and an upper detection tooling assembly 2 for detecting the upward bending are provided at the top of the frame body 1. Both the upper detection tooling assembly 2 and the lower detection tooling assembly 3 are dimensionally matched with the mounting tooling assembly 5.

[0026] In the present invention, the mounting tooling assembly 5 includes two end toolings 501 and a plurality of detachable toolings 502. The two end toolings 501 are respectively fixed on the conveying tooling assembly 4 by bolts. The plurality of detachable toolings 502 can be plugged into and unplugged from the mounting tooling assembly 5. Embedding cavities 505 for placing the heat dissipation fins are provided inside both the end toolings 501 and the detachable toolings 502. A plurality of retaining grooves 507 are provided on both inner walls of the embedding cavity 505. A baffle 503 for blocking and limiting the ends of the heat dissipation fins can be inserted into the two opposite retaining grooves 507. Connecting grooves 504 are provided on both sides of the end toolings 501 and the detachable toolings 502. Two connecting insertion teeth 508 matching with the connecting grooves 504 are provided at the ends of the detachable toolings 502. An elastic locking mechanism is provided between the connecting grooves 504 and the connecting insertion teeth 508. Rubber strips 509 are bonded to both sides of the baffle 503. The rubber strips 509 can contact the inner walls of the retaining grooves 507. By clamping the heat dissipation fins into the embedding cavities 505 provided in the two opposite end toolings 501, the heat dissipation fins are placed and fixed. When placing and fixing heat dissipation fins of different lengths, first, several groups of detachable toolings 502 are determined according to the length of the heat dissipation fins, and then the detachable toolings 502 are clamped into the connecting grooves 504 through the connecting insertion teeth 508, and then the fast insertion and fixing between the detachable toolings 502 and the end toolings 501, as well as between the two detachable toolings 502, are realized through the elastic locking mechanism.

[0027] The elastic locking mechanism in the present invention includes arc-shaped hole grooves 506 respectively formed on the inner walls of one side of the two connecting grooves 504. Inner holes 511 are formed on the inner walls of the opposite sides of the two connecting splines 508. A pin 512 that cooperates with the arc-shaped hole groove 506 is inserted into the inner hole 511. A spring 510 is fixed between the pin 512 and the inner wall of one side of the inner hole 511 by a bolt. By inserting the pin 512 into the arc-shaped hole groove 506, at this time, under the elastic force of the spring 510, the position of the connecting spline 508 is locked and fixed. When disassembling, only need to pull the detachable tooling 502 outwards, and the pin 512 and the arc-shaped hole groove 506 will compress and shorten the spring 510 and achieve the separation action.

[0028] In the present invention, both the upper detection tooling assembly 2 and the lower detection tooling assembly 3 include a mounting frame 201 fixed to the top of the frame body 1 by bolts. A plurality of avoidance sliding frames 203 are inserted into the interior of the mounting frame 201. Two disc springs 204 are fixed between the top end of the avoidance sliding frame 203 and the mounting frame 201 by bolts. A wheel frame 206 is fixed to the bottom end of the avoidance sliding frame 203 through a force sensor 205. An induction wheel 202 is rotatably connected inside the wheel frame 206. The lowest point of the induction wheel 202 in the upper detection tooling assembly 2 is at the same horizontal height as the upper surface of the heat dissipation fin placed in the mounting tooling assembly 5. The highest point of the induction wheel 202 in the lower detection tooling assembly 3 is at the same horizontal height as the lower surface of the heat dissipation fin placed in the mounting tooling assembly 5. The inner bottom walls of a plurality of avoidance sliding frames 203 are all fixed with limit card frames 207 by bolts. A plurality of limit sliding grooves 211 corresponding to the induction wheels 202 are formed inside the mounting frame 201. A limit sliding frame 208 that cooperates with the limit card frame 207 is slidably connected inside the limit sliding groove 211. Magnetic blocks one 209 are fixed to both inner walls of the limit sliding groove 211 by bolts. Magnetic blocks two 210 that generate magnetic attraction fixation with the two magnetic blocks one 209 are fixed to both sides of the limit sliding frame 208 by bolts, and the position of the limit sliding frame 208 is magnetically fixed. The hovering position of the induction wheel 202 is positioned by the disc spring 204. When detecting the deformation degree of the heat dissipation fin, if the heat dissipation fin is bent upward, the induction wheel 202 of the upper detection tooling assembly 2 contacts the bent part of the heat dissipation fin. The induction wheel 202 is stressed and applies pressure to the force sensor 205. At this time, the force received by the force sensor 205 changes and triggers a defective product alarm. The disc spring 204 and the avoidance sliding frame 203 provide avoidance for the upward movement of the induction wheel 202 under stress, avoiding damage to the force sensor 205 caused by hard connection. Similarly, when detecting a heat dissipation fin with a downward bend, it is detected by the induction wheel 202 of the lower detection tooling assembly 3. When detecting heat dissipation fins of different sizes, the number of induction wheels 202 needs to be adaptively adjusted. For example, by sliding the avoidance sliding frame 203 to a specified position, pushing the limit sliding frame 208 into the limit card frame 207, and locking the position of the induction wheel 202. At this time, it is avoided that the redundant induction wheels 202 touch the detachable tooling 502.

[0029] In the present invention, the conveying tooling assembly 4 includes two support frames 407 fixed to the top of the frame body 1 by bolts. Synchronous pulleys 404 are rotatably connected to both ends of the two support frames 407. A synchronous belt 406 is used for driving connection between the two synchronous pulleys 404 located on the same support frame 407. Adjacent synchronous pulleys 404 are connected by a transmission rod 405. A driven pulley 402 is key-connected to the end of the transmission rod 405. A driving motor 403 is fixed to one side of the frame body 1 by bolts. One end of the output shaft of the driving motor 403 is key-connected with a driving pulley 401 which is connected to the driven pulley 402 by a synchronous belt. A collection box 6 for collecting the heat dissipation fins after detection is provided at the end of the frame body 1. By starting the driving motor 403, the driving motor 403 rotates to drive the driven pulley 402 to rotate through the driving pulley 401. The driven pulley 402 rotates to drive the synchronous pulley 404 to rotate through the transmission rod 405, and the synchronous belt 406 wound around the synchronous pulley 404 and the installation tooling assembly 5 are conveyed.

[0030] When the present invention is in use, it includes the following steps: S1: During detection, the heat dissipation fins are placed and fixed by clamping them into the embedding cavities 505 opened in the two opposite end toolings 501. When placing and fixing heat dissipation fins of different lengths, first determine several detachable toolings 502 according to the length of the heat dissipation fins, and then insert the detachable toolings 502 into the connection slots 504 through the connecting splines 508. S2: At this time, the pin 512 is inserted into the arc-shaped hole groove 506, and under the elastic force of the spring 510, the position of the connecting spline 508 is locked and fixed. S3: Then, the number of induction wheels 202 needs to be adaptively adjusted. When adjusting the number, only need to slide the avoidance carriage 203 to the specified position, and push the limit carriage 208 into the limit holder 207 to lock the position of the induction wheel 202. At this time, the extra induction wheels 202 are prevented from touching the detachable tooling 502. S4: Then, by starting the driving motor 403, the driving motor 403 rotates to drive the driven pulley 402 to rotate through the driving pulley 401. The driven pulley 402 rotates to drive the synchronous pulley 404 to rotate through the transmission rod 405, and the synchronous belt 406 wound around the synchronous pulley 404 and the installation tooling assembly 5 are conveyed. S5: Since the hovering position of the induction wheel 202 is positioned by the disc spring 204. S6: When detecting the deformation degree of the heat dissipation fins, if the heat dissipation fins are bent upward, the induction wheel 202 of the upper detection tooling assembly 2 contacts the bent part of the heat dissipation fins. The induction wheel 202 is stressed and applies pressure to the force sensor 205. At this time, the force on the force sensor 205 changes and triggers a defective product alarm, while the disc spring 204 and the avoidance carriage 203 provide avoidance for the upward movement of the induction wheel 202 due to the force; S7: Similarly, when detecting the heat dissipation fins with downward bending deformation, the detection operation is carried out through the induction wheel 202 of the lower detection tooling assembly 3; S8: The heat dissipation fins after detection are conveyed to the end of the conveying tooling assembly 4 through the synchronous belt 406, and then fall into the collection box 6 under the action of gravity.

[0031] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0032] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
