Description

Technical Field

[0001] The present application relates to the field of transfer devices, and in particular to a stapler magazine transfer structure for a stapler stapling machine. Background Art

[0002] Currently, the medical device manufacturing industry, especially in the assembly lines of staplers and related instruments, is experiencing increasing automation. To improve production efficiency and product quality, it is often necessary to introduce advanced automation equipment and technologies.

[0003] A stapler primarily consists of a stapler body and a stapler magazine containing staples. The staples in the magazine are typically assembled on an automated production line. Some stapler models require reversing the magazine during assembly to ensure the staples are positioned correctly in the corresponding magazine.

[0004] Currently, the transfer station of the stapler is usually located by sensors and then reversed by a steering platform. During the reversal process, the stapler loaded with staples will be offset from the steering platform, making it difficult for the stapler to enter the next station accurately, thus affecting the stability of the stapler during transfer. Utility Model Content

[0005] In order to improve the above problems, the present application provides a stapler stapling machine stapler transfer structure.

[0006] The present application provides a stapler stapling machine stapler transfer structure, which adopts the following technical solutions:

[0007] A stapler stapling machine stapler transfer structure is used for transferring the stapler, comprising a frame, a transfer frame and a transfer plate, wherein the transfer frame is arranged on the frame, and the transfer plate is rotatably connected to the transfer frame, and the transfer plate is provided with a first guide plate and a second guide plate opposite to each other on the side facing away from the transfer frame, wherein a guide channel for the stapler to pass through is provided between the first guide plate and the second guide plate, and a limiting component for limiting the stapler is provided on the first guide plate.

[0008] By adopting this technical solution, during the transfer of the staple cartridge, the staple cartridge is pushed between the first and second guide plates. These plates provide guidance for the staple cartridge, reducing the possibility of the staple cartridge shifting during movement. Simultaneously, the limiter assembly applies pressure to the staple cartridge, preventing it from shifting during subsequent rotation of the transfer plate, thereby improving the stability of the staple cartridge during transfer.

[0009] Preferably, the limiting assembly includes a support plate, a support rod and a pressure block, the support plate is arranged on the side of the first guide plate away from the second guide plate, the support rod is arranged on the side of the support plate close to the first guide plate, the first guide plate is provided with a clearance hole, the pressure block is arranged in the clearance hole, and the pressure block is connected to the side of the support rod away from the support plate.

[0010] By adopting the above technical solution, the support plate and the support rod provide support for the pressure block so that the pressure block can apply pressure to the nail magazine more stably, and the yield hole provides guidance for the pressure block, further reducing the possibility of displacement of the nail magazine during transfer, thereby improving the stability of the nail magazine during transfer.

[0011] Preferably, a clearance groove is provided on the side of the pressure block close to the support rod, the support rod is slidably connected to the inner wall of the clearance groove, and a first spring is sleeved on the support rod, one end of the first spring abuts against the support plate and the other end abuts against the pressure block.

[0012] By adopting the above technical solution, when the nail magazine moves to contact the pressure block, the pressure block is squeezed and the first spring is in a compressed state. Under the action of the first spring's rebound force, the pressure block always presses against the nail magazine more stably, further reducing the possibility of displacement of the nail magazine during transfer, thereby further improving the stability of the nail magazine during transfer.

[0013] Preferably, the pressing block is provided with a guiding slope.

[0014] By adopting the above technical solution, the guiding bevel provides guidance for the nail magazine, which on the one hand reduces the possibility of the pressing block damaging the nail magazine, and on the other hand provides convenience for the subsequent limiting of the nail magazine by the pressing block.

[0015] Preferably, a support is provided on the frame, a movable groove is opened on the support, a screw is rotatably connected in the movable groove, a first motor is provided on the support, the output end of the first motor is coaxially connected to the screw, a movable plate is slidably connected in the movable groove, the movable plate is threadedly connected to the screw, and the movable plate is connected to the transfer rack.

[0016] By adopting the above technical solution, the first motor controls the rotation of the screw, which, guided by the movable groove, drives the movable plate to move. The movable plate then drives the transfer rack to adjust the position of the transfer plate to transport the nail magazine to the next station.

[0017] Preferably, a second motor is provided on the transfer rack, and an output end of the second motor is connected to the transfer plate.

[0018] By adopting the above technical solution, the second motor can conveniently control the rotation of the transfer plate to adjust the positions of the transfer plate and the nail magazine.

[0019] Preferably, two opposite positioning rods are provided at the diagonals of the transfer rack, each of the positioning rods is provided with a positioning groove, a positioning column is slidably connected to the positioning groove, a second spring is provided in the positioning groove, one end of the second spring is connected to the bottom of the positioning groove, and the other end is connected to the positioning column, two opposite limiting grooves are provided at the diagonals of the transfer plate, and each of the positioning columns corresponds to a limiting groove.

[0020] By adopting the above technical solution, during the transfer plate's rotation, the transfer plate contacts the positioning post, causing it to retract into the positioning slot. At this point, the second spring is compressed. When the positioning post aligns with the next stop slot, the second spring's rebound force causes the positioning post to snap into the next stop slot, positioning the transfer plate and reducing the possibility of the transfer plate over-rotating.

[0021] Preferably, a side of the positioning column away from the positioning rod is provided with an arc surface.

[0022] By adopting the above technical solution, the arc surface facilitates the separation of the positioning column from the limiting groove at the corresponding position.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By providing a first guide plate, a second guide plate, and a limit assembly, the first and second guide plates provide guidance for the staple cartridge, and the limit assembly provides a limit for the staple cartridge, thereby reducing the possibility of displacement of the staple cartridge during transfer, thereby improving the stability of the staple cartridge during transfer;

[0025] 2. By setting the guiding slope, on the one hand, it provides guidance for the nail magazine, making it easier for the pressure block to limit the nail magazine more stably, and on the other hand, it reduces the possibility of the pressure block damaging the nail magazine;

[0026] 3. By setting positioning columns at the diagonal positions, it is convenient to position the transfer plate and reduce the possibility of excessive rotation of the transfer plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Example 1:

[0034] The embodiment of the present application discloses a stapler stapling machine staple magazine transfer structure. Figure 1 and Figure 2 A stapler stapling machine stapler transfer structure is used for transferring the stapler, and includes a frame 1, a transfer frame 2, and a transfer plate 3. The transfer frame 2 is arranged on the frame 1, and the transfer plate 3 is rotatably connected to the side of the transfer frame 2 facing away from the frame 1. The transfer plate 3 is provided with a first guide plate 31 and a second guide plate 32 opposite to each other, and a guide channel for the movement of the stapler is formed between the first guide plate 31 and the second guide plate 32. A limiting assembly 4 for limiting the position of the stapler is provided on the first guide plate 31. During the transfer of the stapler, the guide channel between the first guide plate 31 and the second guide plate 32 provides guidance for the movement of the stapler, and the limiting assembly 4 provides limitation for the stapler, which reduces the possibility of displacement of the stapler during transfer, thereby improving the stability of the stapler during transfer.

[0035] Reference Figure 1 To facilitate transporting the staple cartridge to different locations, a support 5 is fixed to the frame 1. This support 5 defines a movable slot 51, into which a screw 52 is rotatably connected. Furthermore, a first motor 53 is fixed to the support 5, the output end of which is coaxially fixed to the screw 52. A movable plate 54 is slidably connected to the movable slot 51, threadedly connected to the screw 52, ​​and fixed to the intermediate transfer rack 2.

[0036] In order to facilitate the control of the transfer plate 3 , a second motor 21 is fixed to the transfer frame 2 , and an output end of the second motor 21 is fixed to the transfer plate 3 .

[0037] After the staple cartridge moves between the first guide plate 31 and the second guide plate 32, the first motor 53 is activated and drives the screw 52 to rotate. Guided by the movable slot 51, the screw 52 then drives the movable plate 54 to move. The movable plate 54 then drives the transfer frame 2 to adjust the position of the transfer plate 3. The second motor 21 then controls the rotation of the transfer plate 3 to achieve the function of reversing the direction of the staple cartridge.

[0038] Reference Figure 1 To further enhance the guiding capabilities of the first and second guide plates 31, 32, guide plates 33 are provided on each of the first and second guide plates 31, 32. After the staple cartridge moves between the first and second guide plates 31, 32, the guide plates 33 abut against the upper end surface of the staple cartridge, further guiding the cartridge and improving its stability during transfer.

[0039] Reference Figure 1 and Figure 2 The limiting assembly 4 includes a support plate 41, a support rod 42, and a pressure block 43. The support plate 41 is fixed to the transfer plate 3, the support rod 42 is fixed to the support plate 41, and the pressure block 43 is arranged on the side of the support rod 42 facing away from the support plate 41. The first guide plate 31 is provided with a clearance hole 311, and the pressure block 43 is arranged in the clearance hole 311. The pressure block 43 extends into the guide channel and abuts against the nail magazine.

[0040] Reference Figure 2 and Figure 3 To enhance the ability of the pressure block 43 to retain the staple cartridge, a clearance groove 431 is defined on the side of the pressure block 43 near the support rod 42. The support rod 42 is slidably connected to the inner wall of the clearance groove 431. A first spring 421 is wound around the support rod 42, with one end of the first spring 421 abutting against the support plate 41 and the other end abutting against the pressure block 43.

[0041] As the staple cartridge moves between the first guide plate 31 and the second guide plate 32, the pressing block 43 is squeezed when the staple cartridge contacts the pressing block 43, compressing the first spring 421. After the staple cartridge fully contacts the pressing block 43, the rebound force of the first spring 421 causes the pressing block 43 to rest more stably against the staple cartridge, thereby stably retaining the staple cartridge in position and improving the stability of the staple cartridge during transfer.

[0042] Reference Figure 2 A guiding slope 432 is provided on the pressing block 43. On the one hand, the guiding slope 432 provides guidance for the nail magazine, making it convenient for the pressing block 43 to limit the nail magazine more stably. On the other hand, it makes it difficult for the pressing block 43 to cause damage to the nail magazine.

[0043] The working principle of the first embodiment of the present application is as follows: when the staple cartridge needs to be transferred, the staple cartridge is transported between the first guide plate 31 and the second guide plate 32. At this time, the first guide plate 31 and the second guide plate 32 provide guidance for the staple cartridge. At the same time, the limiting assembly 4 limits the guide plates, making it less likely for the staple cartridge to move during transfer, thereby improving the stability of the staple cartridge during transfer.

[0044] Example 2:

[0045] Reference Figure 4 , which is different from the first embodiment of the present application in that: two opposing positioning rods 6 are fixed at the diagonal points of the transfer frame 2, and each positioning rod 6 is provided with a positioning groove 61, in which a positioning column 62 is slidably connected. A second spring 63 is provided in the positioning groove 61, one end of the second spring 63 is fixed to the positioning column 62, and the other end is fixed to the bottom of the positioning groove 61. Two opposing limiting grooves 34 are provided at the diagonal points of the transfer plate 3, and each positioning column 62 corresponds to a limiting groove 34. An arc surface 621 is provided at the end of the positioning column 62 away from the positioning rod 6.

[0046] The implementation principle of the second embodiment of the present application is as follows: during the rotation of the transfer plate 3, the presence of the arc surface 621 on the positioning post 62 facilitates the separation of the positioning post 62 from the corresponding limiting groove 34. After the positioning post 62 separates from the limiting groove 34, the positioning post 62 is squeezed and the second spring 63 is in a compressed state. After the positioning post 62 is aligned with the limiting groove 34 at the opposite corner, the positioning post 62 is snapped into the limiting groove 34 at the opposite corner under the action of the rebound force of the second spring 63. At this time, the positioning post 62 can position the transfer plate 3, reducing the possibility of excessive rotation of the transfer plate 3, thereby further improving the stability of the nail magazine during transfer.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
