[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0022] like Figure 1-3 As shown, the utility model provides a dust-proof film welding and laser cutting device for a test kit, comprising a frame 1, a welding mechanism 2, a laser cutting mechanism, a positioning jig 4 and a dust-proof film, the welding mechanism 2 and the laser cutting mechanism are arranged on the frame 1, the frame 1 is provided with an operating area 11 for exposing the positioning jig 4, the positioning jig 4 has a plurality of positioning grooves for positioning the outer shell 5; the welding mechanism 2 is used for welding the dust-proof film to the outer shell 5 and closing the piston rod hole 51 on the outer shell 5; the laser cutting mechanism is used for cutting out the excess part of the outer periphery of the dust-proof film, and cutting the surface of the dust-proof film to form a cross mark.
[0023] Through the coordinated action of the welding mechanism 2, the laser cutting mechanism, the positioning jig 4 and the dustproof film, the positioning jig 4 accurately positions the housing 5. The welding mechanism 2 accurately welds the dustproof film to the housing 5, sealing the piston rod hole 51 on the housing 5, so that the piston rod hole 51 is effectively protected by the dustproof film to prevent the intrusion of dust and other pollutants. The laser cutting mechanism cuts the dustproof film, accurately removes the excess part of the outer periphery of the dustproof film, and can also cut a cross mark on the surface of the dustproof film without cutting through the dustproof film, thereby ensuring the integrity of the dustproof film and facilitating the piston rod to pass through the dustproof film later.
[0024] As an optional implementation, Figure 2 As shown, the welding mechanism 2 includes a cylinder slide 21, a lifting cylinder 22, a base plate 23, a mounting plate 24 and a welding head 25. The cylinder slide 21 is arranged on the frame 1, the action end of the cylinder slide 21 is connected to the base plate 23, the fixed end of the lifting cylinder 22 is arranged on the base plate 23, the action end of the lifting cylinder 22 is connected to the mounting plate 24, and the welding head 25 is arranged on the bottom plate of the mounting plate 24, and is arranged one by one with the positioning grooves.
[0025] The cylinder slide 21 drives the base plate 23 to drive the lifting cylinder 22, the mounting plate 24 and the welding head 25 to move in the horizontal direction, so as to ensure that the welding head 25 can accurately move to the designated position above the housing 5 corresponding to the piston rod hole 51.
[0026] The lifting cylinder 22 drives the mounting plate 24 to move the welding head 25 in the vertical direction, so that the welding head 25 is close to or away from the piston rod hole 51 .
[0027] In the initial state of the welding mechanism 2, the cylinder slide 21 and the lifting cylinder 22 are both in their respective initial positions and will not interfere with the laser cutting mechanism.
[0028] When it is necessary to weld the dust-proof film, the cylinder slide 21 drives the lifting cylinder 22 to move the welding head 25 to a designated position above the outer shell 5 corresponding to the piston rod hole 51. Then, the lifting cylinder 22 drives the welding head 25 to move downward until the welding head 25 contacts the dust-proof film on the outer shell 5. The welding operation is performed to accurately weld the dust-proof film to the outer shell 5 and close the piston rod hole 51.
[0029] After the welding operation is completed, the lifting cylinder 22 drives the welding head 25 to move upward, separate from the housing 5, and return to the initial position. The cylinder slide 21 drives the lifting cylinder 22 to drive the welding head 25 to return to the initial position, waiting for the next welding operation.
[0030] Among them, the cylinder slide 21, the lifting cylinder 22, and the welding head 25 adopt the existing technology, which will not be described in detail here.
[0031] As an optional implementation, the base plate 23 is located above the frame 1 .
[0032] As an optional implementation, Figure 2 As shown, the welding mechanism 2 also includes a guide portion, which is symmetrically arranged on both sides of the base plate 23. The guide portion includes a guide rail 26 and a slider 27 that slides with the guide rail 26. The guide rail 26 extends in a direction parallel to the movement direction of the cylinder slide 21, and a limit block 28 is arranged near one end of the cylinder slide 21. The slider 27 is connected to the base plate 23.
[0033] The sliding cooperation between the slider 27 and the guide rail 26 improves the stability and reliability of the movement of the substrate 23 driven by the cylinder slide 21 .
[0034] The limit block 28 is used to limit the position of the substrate 23. When the slider 27 abuts against the limit block 28, the cylinder slide 21 is at an initial position.
[0035] As an optional implementation, Figure 2 As shown, the welding mechanism 2 further includes a limit plate 29 , which is located above the base plate 23 and connected to the mounting plate 24 via a connecting rod 210 . An opening is provided on the base plate 23 for the connecting rod 210 to pass through.
[0036] The limit plate 29 can limit the moving range of the welding head 25 in the vertical direction, so that the welding head 25 can accurately move to the welding position during the descending process driven by the cylinder slide 21.
[0037] As an optional implementation, the laser cutting mechanism includes a laser cutting device 3 , and a laser head 31 of the laser cutting device 3 is located above the operating area 11 and faces the positioning fixture 4 .
[0038] Furthermore, the cross mark is located at the center of the dust-proof film, which is convenient for subsequent quick positioning and identification of the center of the dust-proof film. When the piston rod needs to be inserted, it is only necessary to align the end of the piston rod with the center of the cross mark, and the piston rod can be accurately inserted into the center hole of the dust-proof film.
[0039] The laser cutting device 3 can generate and control a laser beam to perform a cutting operation. The laser cutting device 3 adopts the existing technology, which will not be described in detail here.
[0040] After the welding operation is completed, the welding mechanism 2 returns to the initial position, and the laser beam emitted by the laser head 31 of the laser cutting device 3 can cut the excess part of the outer periphery of the dustproof film according to a preset path and cut a cross mark on the surface of the dustproof film.
[0041] As an optional implementation, the positioning fixture 4 is located below the frame 1 and corresponds to the operating area 11 .
[0042] The frame 1 can be mounted on a transmission mechanism, and the transmission mechanism can drive the positioning fixture 4 to pass through the operating area 11 in sequence.
[0043] The transmission mechanism drives the positioning fixture 4 and the housing 5 to move along a preset path. When the positioning fixture 4 moves to the bottom of the operating area 11, the welding mechanism 2 and the laser cutting mechanism operate according to the preset program, that is, the welding head 25 accurately welds the dustproof film to the piston rod hole 51 of the housing 5 to achieve the closure of the piston rod hole 51. After the welding is completed, the welding mechanism 2 returns to the initial position and waits for the next operation. Then, the laser head 31 of the laser cutting device 3 emits a laser beam to cut the excess part of the outer periphery of the dustproof film according to the preset path. At the same time, a cross mark is cut on the surface of the dustproof film to provide a positioning reference for the subsequent piston rod insertion.
[0044] After the laser cutting operation is completed, the transmission mechanism moves the positioning fixture 4 that has completed the operation out of the operation area 11 , transmits it to the next process, and moves the next positioning fixture 4 to be processed to the operation area 11 .
[0045] It should be noted that the transmission operation of the transmission mechanism and the positioning fixture 4 is one of the conventional processes in the existing medical device production.
