A butt plate is one of the most important components of the anastomat, and the butt plate is usually composed of a bottom plate and two sheet bodies by an intelligent welding system at present, that is, the intelligent welding system precisely acts on a welding point by an automatic positioning structure and a laser welding head, and compared with other welding methods, the intelligent welding system can greatly avoid thermal damage to the surrounding precision structure.

DETAILED DESCRIPTION

[0018] Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0019] Embodiment: as Figures 1-12As shown, the present invention provides a technical solution: a stapler processing device with mold switching function. The stapler processing device includes a base 1 and a housing 3. The housing 3 is mounted on the base 1. A switching disk 2 is located at the middle of the upper end of the base 1. A moving module 4 is located on the side of the switching disk 2. A laser welding mechanism 5 is mounted on the moving module 4. The moving module 4 controls the lifting and horizontal movement of the laser welding mechanism 5. A reducer 11, a rotary motor 12, and a calibration mechanism 13 are installed inside the base 1. The input end of the reducer 11 is connected to the rotary motor 12. The output end of the reducer 11 is connected to the switching disk 2 via the calibration mechanism 13. The switching disk 2 has several grooves, each containing a set of fixed molds 21. During operation, the operator places the anastomosis device components to be welded onto a set of fixed molds 21 near the opening of the housing 3. Then, the switching disk 2 is rotated by the rotary motor 12, causing the fixed molds 21 containing the anastomosis device components to move below the laser welding mechanism 5. The laser welding mechanism 5 then welds the anastomosis device components. During the welding process of the stapler components, the operator can place the next stapler component onto a set of fixed molds 21 near the opening of the housing 3. This technical solution avoids the waiting time for welding and loading processes in traditional equipment. Finally, compared with the current stapler processing device, the present invention also has a calibration mechanism 13. The calibration mechanism 13 detects whether the rotation angle of the switching disk 2 is correct, thereby ensuring that after each switch, a set of fixed molds 21 accurately stops directly below the laser welding mechanism 5, ensuring the consistency and accuracy of the welding position. On the other hand, when the rotary motor 12 drives the switching disk 2 to rotate, if the rotation angle deviates due to a malfunction or a sudden stop occurs, the calibration mechanism 13 can make the switching disk 2 continue to rotate to the set angle. At this time, the operator can remove the rotary motor 12 from the base 1 for repair or replacement. During the repair or replacement of the rotary motor 12, the calibration mechanism 13 will serve as the power source for the rotation of the switching disk 2 to ensure that several fixed molds 21 can be switched normally, thereby ensuring the continuity of stapler processing.

[0020] like Figures 2-3 As shown, each groove has a reversing motor on its side, and each reversing motor is connected to a set of fixed molds 21.

[0021] As shown in Figures 4-7 , the upper middle position of the support seat 212 is provided with a positioning strip 2122, the two sides of the positioning strip 2122 are respectively provided with a limiting assembly 213, the anastomat to be welded component is usually composed of a bottom plate and a sheet body, the sheet body is placed on the bottom plate through the cooperation of the limiting assembly 213 and the positioning strip 2122.

[0024] As shown in the figure, Figures 4-7 As shown, the limiting assembly 213 comprises a mounting frame 2131, a third electromagnet 2132 and a plurality of limiting pins 2133, the plurality of limiting pins 2133 are arranged on the upper end of the mounting frame 2131, the third electromagnet 2132 is arranged on the lower end of the mounting frame 2131, and a permanent magnet is arranged on one end of each limiting pin 2133 close to the third electromagnet 2132, during the process that the to-be-welded part of the anastomat is placed on the support base 212, the plurality of limiting pins 2133 are controlled to extend out of the mounting frame 2131 by the third electromagnet 2132, and the plurality of limiting pins 2133 and the positioning strip 2122 cooperate to facilitate the worker to place the sheet on the bottom plate, after the to-be-welded part of the anastomat is completely placed on the support base 212 and is clamped and fixed, the plurality of limiting pins 2133 are controlled to retract into the mounting frame 2131 by the third electromagnet 2132, so as to facilitate the laser welding mechanism 5 to weld the side surface, the end surface and other directions of the to-be-welded part of the anastomat.

[0025] As shown in the figure, Figure 2 , Figures 8-12As shown, the calibration mechanism 13 includes a first fixed plate 131, a second fixed plate 132, and a rotating shaft 133. The first fixed plate 131 is fixedly installed inside the top of the machine base 1, and the second fixed plate 132 is located below the first fixed plate 131. The rotating shaft 133 passes through the first fixed plate 131 and the second fixed plate 132. One end of the rotating shaft 133 is connected to the output end of the reducer 11, and the other end of the rotating shaft 133 is connected to the switching plate 2. A first gear 1331 is provided at the middle position of the rotating shaft 133, and a detection element is provided on the side end of the first gear 1331. The first gear 1331 is connected to the detection element. The reducer 11 and the rotating shaft 133 are driven by the rotary motor 12. The rotating shaft 133 causes the switching plate 2 to rotate continuously at a specific angle to achieve the function of mold switching. During the rotation of the switching plate 2, the detection element monitors in real time whether the rotation angle of the switching plate 2 is correct to ensure that after each switching, a set of fixed molds 21 accurately stays directly below the laser welding mechanism 5.

[0026] like Figures 8-11 As shown, the detection element includes a fixed shaft 134 and a third gear 1342. The third gear 1342 is mounted on the fixed shaft 134.

Several light-shielding blocks 13421 are disposed on one side of the third gear 1342 near the calibration groove 1321. Each light-shielding block 13421 has a photosensitive element 13422 on its side. The dimensions of the light-shielding blocks 13421 are the same as the dimensions of the light-emitting elements 1322. When the rotating shaft 133 drives the switching disk 2 to rotate, the first gear 1331 synchronously drives the third gear 1342 to rotate around the fixed shaft 134. At the same time, the positional distribution of several light-shielding blocks 13421 is the same as the distribution of several fixed molds 21. When a set of fixed molds 21 is located directly below the laser welding mechanism 5, a set of light-shielding blocks 13421 will be aligned with the light-emitting element 1322. Through the above technical solution, the operator can indirectly determine whether the rotation angle of the switching disk 2 is correct by detecting the signals emitted by several photosensitive elements 13422.

[0028] The working principle of the present application: before work, the positioning block 214 on the shaft seat 215 is first pried open, then the distance between the two limiting assemblies 213 is adjusted through the two screw rod assemblies 2121, so as to facilitate the workers to place the anastomat parts to be welded on the support seat 212, when the anastomat parts to be welded are placed on the support seat 212, the positioning block 214 is reset by rotating, so that the positioning block 214 is close to the support seat 212, then the support seat 212 is controlled to rise through the adjusting assembly, until the anastomat parts to be welded are in contact with and clamped by the positioning block 214, finally the switching disc 2 is driven to rotate by the rotating motor 12, so that the fixed mold 21 on which the anastomat parts to be welded are placed is moved below the laser welding mechanism 5, the anastomat parts to be welded are welded by the laser welding mechanism 5, during the process of welding the anastomat parts to be welded, the workers can place the next anastomat parts to be welded on a group of fixed molds 21 close to the opening of the cabinet 3, during the work process, the calibration mechanism 13 detects whether the rotation angle of the switching disc 2 is correct, so as to ensure that each time after switching, a group of fixed molds 21 accurately stay directly below the laser welding mechanism 5, when the rotating motor 12 drives the switching disc 2 to rotate, if the rotation angle deviates due to failure, or suddenly encounters a phenomenon such as shutdown, the calibration mechanism 13 can make the switching disc 2 continue to rotate to the set angle, at this time the workers can remove the rotating motor 12 from the machine base 1 for maintenance or replacement, during the process of maintenance or replacement, the calibration mechanism 13 will serve as the power source for the rotation of the switching disc 2.
