[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example:
[0029] Please see Figure 1 - Figure 6 The automatic precision welding device for disposable surgical minimally invasive scalpels in this embodiment includes a welding table 1, a scalpel head 7, and a scalpel body 701. The welding table 1 is equipped with a feeding mechanism, a clamping and moving mechanism, a welding mechanism, and a positioning mechanism.
[0030] The feeding mechanism consists of a short material feeding section for feeding the cutter head 7 and a long material feeding section for feeding the user's cutter body 701. The clamping and moving mechanism consists of a short material clamping section for clamping the cutter head 7 and a long material clamping section for clamping the cutter body 701.
[0031] The positioning mechanism includes a limiting guide bar 603 that is inserted and connected to both the cutter head 7 and the cutter body 701;
[0032] The welding mechanism includes a camera 502 for positioning the connection between the cutter head 7 and the cutter body 701, and a welding head 501 for welding the connection between the cutter head 7 and the cutter body 701.
[0033] The cutting tool consists of a cutting head 7 and a cutting body 701. The cutting body 701 is longer than the cutting head 7. The cutting body 701 and the cutting head 7 have the same cross-sectional specifications and are internally connected. The middle part of the cutting body 701 is through-type. The middle part of the cutting head 7 is through-type at one end and sealed at the other end. Its feeding, clamping and moving are both composed of two parts.
[0034] The cutting head 7 and the cutting body 701 are simultaneously fed into the short material section and the long material section respectively, and the cutting head 7 and the cutting body 701 are moved to the clamping part. Then, under the multiple clamping of the cutting head 7 and the cutting body 701 by the short material clamping part and the long material clamping part, the cutting head 7 and the cutting body 701 are moved laterally into the positioning mechanism and the connecting surfaces of the cutting head 7 and the cutting body 701 are placed in contact. Then, the detailed connection status of the cutting head 7 and the cutting body 701 is captured by the camera 502, and the connection is welded and fixed by controlling the operation of the welding head 501.
[0035] After the cutting head 7 and the cutting body 701 are positioned, the limiting guide 603 is moved to insert into the cutting body 701 and the cutting head 7, and is positioned and guided from inside the connection to prevent the position from shifting during the welding process, thereby further improving the precision of the welding joint.
[0036] The short material feeding section includes a vibratory feeder 2 for vibratory feeding support and a feeding rail 201 for feeding guide support;
[0037] The upper material section includes a feeding box 3 for supporting material placement and a guide plate 301 for automatic material sliding support. The guide plate 301 is installed at an incline at the bottom of the feeding box 3, and a guide space is formed between the lower part of the guide plate 301 and the inner bottom edge of the feeding box 3. The specifications of the guide space are consistent with the specifications of a blade 701.
[0038] The upper material section also includes a telescopic motor 302 and a push plate 303. The telescopic motor 302 is installed at the lower end of the feeding box 3, and the push plate 303 is installed at the output end of the telescopic motor 302. The push plate 303 is slidably installed inside the moving groove in the middle of the lower end of the feeding box 3, and the upper surface of the push plate 303 contacts the lower surface of the guide plate 301 at a low point.
[0039] Under the guidance and support of the feeding rail 201, the cutter head 7 vibrated out of the vibrating feeder 2 can be moved in a fixed direction, so that the cutter head 7 can be moved to the accurate position. Under the support of the inclined guide plate 301 itself, the cutter body 701 placed inside the feeding box 3 can automatically move in the guide space. Under the reciprocating push of the push plate 303, the cutter body 701 moves one by one to the clamping position.
[0040] Specifically, under the separate guidance and simultaneous operation of the feeding mechanism, the cutter head 7 is moved to the accurate position through the combination of the vibrating feeder 2 and the feeding rail 201. When the cutter body 701 automatically slides into the guide space, the pusher plate 303 is controlled to reciprocate under the drive of the telescopic motor 302. Based on the specifications of the guide space, one cutter body 701 is allowed to flow at the same time. When the outer edge of the pusher plate 303 moves to the bottom of the guide inclined plate 301, the cutter body 701 moves to the outside of the pusher plate 303 through the guide space. Under the reset movement of the pusher plate 303, the cutter body 701 is pushed to the outer clamping part, so that the cutter head 7 and the cutter body 701 are moved to the accurate position for use.
[0041] By setting the internal dimensions of the feeding box 3 according to the length of the blade 701, it effectively prevents the blade from shifting during automatic sliding. The feeding method inside the feeding box 3 is manual. When the blade 701 shifts position inside, it can be manually adjusted and straightened to ensure the accuracy and reliability of the feeding status.
[0042] The clamping and moving part is provided with a drive assembly 4 for driving support of the short material clamping part and the long material clamping part. The lower end of the drive assembly 4 is equipped with a short jaw 402 for clamping the cutter head 7 and at least two long jaws 401 for clamping the cutter body 701.
[0043] Based on the three-axis drive of drive component 4, the lower drive component 4 and the long gripper 401 can move in multiple directions. Since its three-axis drive method is a conventional existing technology, it is not described in detail in this embodiment. It is sufficient to set drive component 4 to have multi-directional drive. Therefore, there is no restriction on its specific control method. Different control methods can be selected and used according to the actual use.
[0044] After the long gripper 401 behind the short gripper 402 clamps the blade 701, under the control of the drive component 4, the blade 701 is moved to the side of the cutter head 7 and then the long gripper 401 is reset and moved to clamp the blade 701 again. At the same time, the long gripper 401 in front and the long gripper 402 will move down simultaneously. At this time, the long gripper 401 on the horizontal side of the short gripper 402 clamps the blade 701, and the short gripper 402 clamps the cutter head 7. This allows the long gripper 401 and the short gripper 402 on the same side to clamp and position the blade 701 and the cutter head 7 simultaneously, forming a three-station clamping combination. The clamping drive method of the long gripper 401 and the short gripper 402 can be used with various existing methods such as traditional motor drive and screw drive, so it is not described in detail here.
[0045] The combination of a short gripper 402 and two long grippers 401 clamps a set of cutting heads 7 and blades 701 in a horizontal position, ensuring accurate positional distribution between them. When moved to the welding mechanism, the rear long gripper 401 moves to the side of the cutting head 7 while being clamped by the blade 701, providing precise placement support for the simultaneous movement of the next set of cutting heads 7 and blades 701. The cutting head 7 and blades 701 are placed on a support portion on one side of the feed rail 201, which is used for temporary placement support of the cutting head 7 and blades 701. The actual placement device can be adjusted according to actual needs, so it is not limited in this embodiment.
[0046] The positioning mechanism includes a clamping member 6 for positioning and supporting both ends and a clamping member 601. The clamping member 6 is used for positioning and placing the cutting head 7, and the clamping member 601 is used for positioning and placing the cutting body 701. The positioning mechanism also includes a clamping member 602 for positioning and placing the limiting guide 603. The limiting guide 603 is simultaneously inserted into the clamping member 601, the cutting head 7, and the cutting body 701.
[0047] The welding mechanism includes a drive assembly 503 for moving and supporting the welding head 501 and the camera 502, and a welding machine 5 mounted on the welding head 501 for providing welding.
[0048] Clamping component 1 6 and clamping component 2 601 provide clamping and rotational support for the cutting head 7 and the cutting body 701, respectively, and provide rotational support for welding of the welding head 501, so that welding can be performed at the annular connection between the cutting head 7 and the cutting body 701. Under the rotation and pushing guidance of clamping component 3 602, the limiting guide 603 moves to the cutting head 7 and the cutting body 701 and can rotate synchronously with them. While ensuring the connection and limiting support of the cutting head 7 and the cutting body 701 from the inside, it prevents damage to the inner wall when it is stationary. The operation mode of the rotation, clamping and pushing parts of clamping component 2 601, clamping component 1 6 and clamping component 2 601 are all existing technologies, so they are not described in detail in this embodiment.
[0049] When the clamping mechanism moves the cutting head 7 and the cutting body 701 between clamping member 1 6 and clamping member 2 601, clamping member 1 6 clamps and fixes the cutting head 7, and clamping member 2 601 clamps and fixes the cutting body 701. Then, clamping member 3 602 is activated. Based on the fact that the outer diameter of the limiting guide 603 is slightly smaller than the inner diameter of the cutting body 701 and the cutting head 7, the limiting guide 603 is pushed to penetrate and insert into clamping member 2 601 and the cutting body 701, and is inserted into the inside of the cutting head 7. It provides limiting guidance from the middle for the connection between the cutting head 7 and the cutting body 701. Then, clamping member 1 6 and clamping member 2 601 push the cutting head 7 and the cutting body 701 to gradually clamp. With the synchronous rotation support of clamping member 1 6, clamping member 2 601 and clamping member 3 602, the welding head 501 is precisely and stably welded.
[0050] Among them, the second drive component 503 is an existing three-axis drive mechanism, which provides movement support for the operation of the welding machine 5, the welding head 501, and the camera 502, enabling it to have the effect of position adjustment. Under the capture of the camera 502, the state of the connection between the cutter head 7 and the cutter body 701 can be accurately obtained, providing data support for the accuracy of the connection.
[0051] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
