[0002] Thermal biopsy forceps refers to a tool used for thermal biopsy, which is usually made of metal and has a pair of clamps and a heating element. The main function of thermal biopsy forceps is to perform biopsy surgery in the medical field to obtain tissue samples for pathological examination. It can quickly and accurately obtain tissue samples. It plays an important role in some pathological research and clinical diagnosis. Using thermal biopsy forceps for biopsy surgery can usually reduce bleeding and tissue damage, and improve the accuracy and efficiency of the operation.
[0003] The internal insert in the conductive positioning cap of the thermal biopsy forceps is generally assembled manually, and the assembly efficiency is very low. The internal insert is often not assembled in place, and the position of the insert is offset. The internal insert is then assembled into the conductive positioning cap through an assembly mold. Since the position of the insert is offset, it is easy to cause the insert to be crushed and cause damage to the assembly mold. Once the mold is damaged, it will incur high mold repair costs and delay production orders. Based on the above technical problems, the prior art has designed an injection mold for making a conductive positioning cap for thermal biopsy forceps, with a publication number of CN220946413U, which solves the positioning problem of the insert in the mold.

[0025] Example 1
[0026] Reference Figure 1 to Figure 4 The present embodiment provides an automatic assembly device for the internal insert of a conductive positioning cap for a thermal biopsy forceps, including a carrier plate 100, a cylinder is arranged on the carrier plate 100, a piston rod 101 is connected to the cylinder, a first grabbing member 200 is fixed to the end of the piston rod 101, and a second grabbing member 300 is arranged on the carrier plate 100; it also includes an injection mold 400, and an injection hole 401 and a positioning hole 402 are arranged on the injection mold 400; the carrier plate 100 is connected to a robot arm.
[0027] In this embodiment, the first gripping member 200 is used to grip the insert, assemble the insert onto the injection mold and then perform injection molding, and the second gripping member 300 is used to remove the injection-molded conductive positioning cap from the injection mold 400 .
[0028] Furthermore, positioning pins 102 are provided on the carrying plate 100 , and the positioning pins 102 are located at two ends of the first grabbing member 200 .
[0029] The positioning pin 102 is used for preliminary positioning to ensure that the insert grasped by the first grasping member 200 is accurately embedded in the injection hole 401 of the mold.
[0030] Furthermore, the positioning pin 102 includes a fixed tube 102a and an insertion rod 102b disposed in the fixed tube 102a, a frustum 102c is disposed at the end of the insertion rod 102b, and a spring 102d is disposed on one side of the frustum 102c and connected to the fixed tube 102a.
[0031] The frustum 102c is used for fault tolerance, and the end of the frustum 102c is a small head, which is easier to be assembled into the positioning hole 402 of the mold.
[0032] Furthermore, the first grabbing member 200 includes a side plate 201 and a plurality of grabbing shafts 202 disposed on the side plate 201 .
[0033] The grabbing shafts 202 are regularly arranged on the side plate 201. The embodiment adopts a 2-column 4-row arrangement, and 8 grabbing shafts 202 are arranged on the side plate 201. Similarly, 8 injection holes 401 are correspondingly arranged on the injection mold 400, and 8 inserts can be installed and injection-molded at the same time.
[0034] Furthermore, the grabbing shaft 202 includes a bottom shaft 202a and an embedded shaft 202b, a folding spring sheet 202c is provided on the side of the embedded shaft 202b, and the end of the folding spring sheet 202c is fixed on the bottom shaft 202a; the folding spring sheet 202c is fixed to the bottom shaft 202a by bolts.
[0035] The insert is a tubular structure with a groove in the center. The process of grabbing the insert is as follows:
[0036] The insert is fixed, and the robot arm controls the carrier plate 100 to approach the insert. After the grabbing shaft 202 is matched with the insert, the cylinder controls the first grabbing member 200 to move as a whole, the embedding shaft 202b is inserted into the insert, and the folded spring piece 202c is inserted into the insert to fix and grab it. Then the cylinder controls the first grabbing member 200 to retract, and controls the robot arm to match another grabbing shaft 202 with another insert, and continues to grab. This is done eight times to fill the single first grabbing member 200 with the insert.
[0037] Furthermore, the second gripping member 300 includes a tube column 301 and a suction head 302 disposed at the end of the tube column 301. The tube column 301 is hollow and connected to a negative pressure tube and an air pump to suck the conductive positioning cap after injection molding.
[0038] After the injection molding is completed, the robot arm controls the second grabbing member 300 to approach the mold to absorb the conductive positioning cap. Since high precision is not required for taking the part out of the mold, no positioning pin is required.
[0039] Furthermore, the inserts can be ejected one by one in sequence by designing an ejection mechanism, so that the robot arm can control the first grasping member 200 to position and grasp, which will not be described in detail herein.
[0040] The utility model can control the load-bearing plate to use the first grasping member to grasp the insert and accurately install it on the mold, and use the second grasping member to absorb the conductive positioning cap after injection molding. After absorption, they can be placed in designated packaging bags respectively, and the process of placing them in the packaging bags will not be repeated.
[0041] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
