Detailed Implementation

[0032] The core of this invention is to provide a sample tube sealing aluminum foil removal device. The structural design of this device enables the removal of the sample tube sealing aluminum foil before re-inspection, thus avoiding the collision phenomenon of the testing instrument.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of the sample tube sealing aluminum foil removal device provided in an embodiment of the present invention.

[0035] This invention discloses a sample tube sealing aluminum foil film removal device, which includes a lifting mechanism, a film lifting mechanism, and a film pressing mechanism.

[0036] The film-raising mechanism and the film-pressing mechanism are located at the lifting end of the lifting mechanism. The lifting mechanism is used to drive the film-raising mechanism and the film-pressing mechanism to move up and down. The film-raising mechanism includes a film-raising claw and a film-raising drive device. The film-raising claw is located at the drive end of the film-raising drive device. The film-raising drive device is used to drive the film-raising claw to move closer to or away from the sample tube. The film-pressing mechanism includes a film-pressing claw and a film-pressing drive device. The film-pressing claw is vertically and vertically positioned above the film-raising claw through the film-pressing drive device. The film-pressing claw is used to cooperate with the film-raising claw to clamp the aluminum foil film sealing the sample tube.

[0037] As can be seen, compared with the prior art, the sample tube sealing aluminum foil removal device provided in this embodiment of the invention, when the sample tube is in place, the lifting mechanism drives the film lifting mechanism and the film pressing mechanism to descend to the working position. The film lifting claw of the film lifting mechanism is driven by the film lifting driving device to approach the outer wall of the sample tube, and then moves upward under the drive of the lifting mechanism to lift the aluminum foil film adhering to the outer wall of the sample tube at the sample tube opening. Then, the film pressing claw descends under the drive of the film pressing driving device to cooperate with the film lifting claw to clamp the aluminum foil film. Finally, the lifting mechanism rises to remove the aluminum foil film from the sample tube. It can be seen that the above-mentioned sample tube sealing aluminum foil removal device can peel off the sealing aluminum foil film from the sample tube, so as to avoid the collision phenomenon of the connected detection instrument during the subsequent re-inspection process, which would cause damage to the instrument.

[0038] The lifting mechanism includes a support frame 110, a horizontal moving device 120, and a vertical moving device 130.

[0040] The vertical drive device includes a vertical drive motor 131 and a first lead screw and slider mechanism 132. The lead screw of the first lead screw and slider mechanism 132 is connected to the output end of the vertical drive motor 131, and the slider of the first lead screw and slider mechanism 132 is connected to the vertical sliding mounting base 135.

[0041] The vertical moving device also includes a vertical mounting base 133, which is fixed to a horizontal sliding mounting base 125. A vertical drive motor 131 is also mounted on the vertical mounting base 133.

[0042] The film-forming drive device includes a film-forming drive motor 201 and a first gear and rack mechanism. The first gear 203 of the first gear and rack mechanism is located at the output end of the film-forming drive motor 201, and the first rack 204 of the first gear and rack mechanism is connected to the film-forming claw 205.

[0043] from Figure 5 As can be seen, the film-forming mechanism 2 is provided with two film-forming claws 205, which are arranged opposite to each other. The first gear and rack mechanism includes a first gear 203 and two first racks 204. The two first racks 204 are on both sides of the first gear 203 and mesh with the first gear 203 respectively. Each first rack 204 is connected to a film-forming claw 205.

[0044] The film-forming mechanism 2 also includes a film-forming support 202 for fixing the aforementioned film-forming drive motor 201, the first gear rack mechanism, and the film-forming claw 205. The bottom of the film-forming support 202 is provided with a film-forming claw slide rail 206, and the film-forming claw 205 slides in cooperation with the film-forming claw slide rail 206.

[0045] The film pressing mechanism 3 is fixed on the film lifting bracket 202 by the film pressing bracket 302. The film pressing drive device includes a film pressing drive motor 301 and a second lead screw slider mechanism 303. The output end of the film pressing drive motor 301 is connected to the lead screw of the second lead screw slider mechanism 303, and the slider of the second lead screw slider mechanism 303 is connected to the film pressing claw.

[0046] The pressing claw includes a fixing part 304, a pressing part 305, and an elastic element 306. The fixing part 304 and the pressing part 305 are respectively slidably disposed on the slide rail of the second lead screw slider mechanism 303. The fixing part 304 is fixedly connected to the slider of the second lead screw slider mechanism 303, and the pressing part 305 is connected to the fixing part 304 through the elastic element 306.

[0047] The film pressing mechanism also includes a film pressing claw position detection device. The trigger end 307 of the film pressing claw position detection device is disposed on the film pressing part 305, and the detection end 308 of the film pressing claw position detection device is disposed on the slide rail of the second lead screw slider mechanism 303. When the detection end 308 of the film pressing claw position detection device detects the trigger end 307 of the film pressing claw position detection device, the film pressing drive motor 301 completes the reset to the origin.

[0048] The aforementioned sample tube sealing aluminum foil removal device also includes a sample tube clamping mechanism 4 disposed below the film-raising mechanism 2 and the film-pressing mechanism 3. The sample tube clamping mechanism 4 includes a support base 406, a gripper mounting base 416, grippers, and a clamping drive device. Multiple gripper mounting bases 416 are arranged parallel and spaced apart on the support base 406, and at least one gripper mounting base 416 is slidably disposed on the support base 406. Multiple grippers are arranged one-to-one on each gripper mounting base 416, and at least one gripper is slidably disposed on the gripper mounting base. 416 A reset member 410 is provided between the gripper and the gripper mounting base 416, so that the clamping force of the sample tube clamping device 4 can be adjusted. The clamping force of the sample tube clamping device 4 can be further adjusted by replacing the reset member 410 with a different elastic coefficient, so that it can be compatible with sample tubes of different diameters and can effectively clamp sample tubes of different diameters. The clamping drive device is used to drive each gripper mounting base 416 to drive each gripper to move together to clamp the sample tube or to move apart to release the sample tube.

[0049] In this embodiment of the invention, each gripper is slidably disposed on each gripper mounting base 416, and a reset member 410 is provided between each gripper and the corresponding gripper mounting base 416. That is, each gripper can make a certain displacement relative to the gripper mounting base 416 within the range allowed by the reset member 410. When the driving device drives the gripper mounting base 416 to move closer to the other gripper mounting bases 416 relative to the support base 406 until each gripper contacts the sample tube, the driving device continues to operate. At this time, since the gripper cannot move forward after contacting the sample tube, the gripper mounting base 416 compresses the reset member 410 between itself and the gripper. The elastic force generated by the compression of the reset member 410 acts on the gripper to hold the sample tube.

[0050] To further optimize the above technical solution, the gripper mounting base 416 is provided with a stop 409. The stop 409 is located on the side away from the gripper's clamping end via the stop mounting base 407. The stop 409 is provided with a through hole for the guide rod 414 to pass through. The guide rod 414 passes through the through hole and connects to the gripper. The reset member 410 is sleeved on the guide rod 414.

[0051] like Figure 6 and Figure 7 As shown, in this embodiment of the invention, the gripper includes a slide 408, a vertical plate 411, and a gripping head 413. The slide 408 is slidably engaged with the gripper mounting base 416. One of the slide 408 and the gripper mounting base 416 is provided with a guide rail 415, and the other of the slide 408 and the gripper mounting base 416 is provided with a groove that mates with the guide rail 415. The slide 408 and the gripper mounting base 416 are slidably connected through the engagement of the guide rail 415 and the groove. The two ends of the vertical plate 411 are respectively connected to the slide 408 and the gripping head 413 to form an S-shaped structure. The gripping heads 413 of each gripper are arranged facing each other. The reset member 410 is disposed between the vertical plate 411 and the stop block 409. The gripping head 413 serves as the gripping end of the gripper for gripping the sample tube.

[0052] Preferably, the clamping head 413 is connected to the upright plate 411 via a pad 412, and the clamping force of the sample tube clamping device can be adjusted by replacing the pads 412 of different thicknesses.

[0053] The aforementioned clamping head 413 can be made of a material with a certain elasticity and rough texture, or an elastic friction pad can be provided on the surface of the clamping head 413 that contacts the sample tube to increase the friction between the clamping head 413 and the sample tube, so as to prevent the sample tube from rotating relative to the clamping claw during the opening process of the sample tube.

[0054] To further optimize the above technical solution, each of the gripper mounting seats 416 is slidably disposed on the support seat 406. The driving device is used to drive each gripper mounting seat 416 to drive each gripper to synchronously gather together or disperse. Accordingly, a driving device can be set for each gripper mounting seat 416, or only one driving device can be set. The output end of the driving device is connected to each gripper mounting seat 416 through a transmission device to realize the synchronous action of each gripper mounting seat 416.

[0055] The aforementioned driving device is a piston cylinder, such as a hydraulic cylinder or a pneumatic cylinder; or the driving device is a linear motor; or the driving device includes a rotary motor 401 and a transmission mechanism, the transmission mechanism being used to convert the rotary motion of the rotary motor 401 into linear reciprocating motion, the transmission mechanism including but not limited to a cam linkage mechanism, a gear rack mechanism, and a lead screw slider mechanism.

[0056] Specifically, such as Figure 6 and Figure 7 As shown, the above-mentioned sample tube clamping device includes two opposing gripper mounting bases 416, such as... Figure 6 As shown, one of the gripper mounting base 416 and the support base 406 is provided with a guide rail 417, and the other of the gripper mounting base 416 and the support base 406 is provided with a sliding groove adapted to the guide rail 417. The gripper mounting base 416 and the support base 406 are slidably connected through the cooperation of the guide rail 417 and the corresponding sliding groove. The driving device includes a gripping drive motor 401, a second gear and rack mechanism, and two connecting members 418. The second gear and rack mechanism includes a second gear 403. And two second racks 404, the second gear 403 is disposed at the output end of the clamping drive motor 401, the two second racks 404 are on both sides of the second gear 403 and respectively mesh with the second gear 403, the second racks 404 are connected to the corresponding gripper mounting base 416 through the connecting member 418, so that when the clamping drive motor 401 drives the second gear 403 to rotate, the two second racks 404 will move towards each other or away from each other to realize the mutual convergence or divergence of the two gripper mounting bases 416.

[0057] To further optimize the above technical solution, the sample tube clamping device 4 also includes a mounting plate 402. The two ends of the support base 406 are respectively suspended on one side surface of the mounting plate 402 through the bottom of the support block 405. The clamping drive motor 401 is set on the other side surface of the mounting plate 402. The output end of the clamping drive motor 401 passes through the mounting plate 402 and is connected to the second gear 403 set between the support base 406 and the mounting plate 402.

[0058] In order to effectively control the operation of the driving device, the sample tube clamping device 4 also includes a position detection device and a controller. The position detection device includes a detection end 420 and a trigger end 419. The detection end 420 is disposed on the mounting plate 402, and the trigger end 419 is disposed on the gripper mounting base 416. In this embodiment of the invention, the trigger end 419 is disposed on the gripper mounting base 416 through a connecting member 418. The controller is used to confirm whether the clamping head 413 has reached the designated position after the driving device is activated when the detection end 420 detects the trigger end 419.
