[0049] As Figures 2 - 4 shown, the curing system includes a housing 10, a support mechanism, and a lamp head mechanism 3. Among them:

[0050] The housing 10 serves as the framework of the curing system. Its four sides are enclosed for shielding, and an opening 100 is provided at the top. The catheter can be installed through the opening 100. In the illustration, the opening 100 is only opened above the support mechanism, and the upper part of the lamp head mechanism 3 is also closed. In this embodiment: The housing 10 is made of black POM material, and the shielding effect is better.

[0051] A cover 11 is connected to the housing 10, and the cover 11 can shield the opening 100 of the housing 10. In this embodiment: The cover 11 is slidably connected to the housing 10, that is, the opening of the housing can be opened or closed by sliding the cover 11. Sliding open the cover 11 allows the catheter to be installed, and sliding closed the cover 11 allows curing, thus facilitating the operator to open or close.

[0052] As Figure 5 shown: The support mechanism is arranged inside the housing 10. The support mechanism includes a fixed support 20 and a rotating support assembly. A curing area 22 is formed between the fixed support 20 and the rotating support. Among them:

[0053] The fixed support 20 is fixedly connected to the bottom of the housing 10. A groove 200 is formed on the upper surface of the fixed support 20, and the tube body 51 of the catheter can be supported in the groove 200 of the fixed support 20. In this embodiment: The groove 200 is V-shaped. The V-shaped groove 200 can prevent the tube body 51 of the catheter from shifting and better position it while providing support. Of course, the fixed support 20 can also be arranged in a form where the distance between it and the rotating support assembly is adjustable to support catheters of different lengths. Its structure can be a sliding adjustment method, etc., which will not be elaborated here.

[0054] The rotating support assembly includes a pair of brackets 210 and a thimble. Among them: The brackets 210 are fixedly connected to the bottom of the housing 10, the thimble is rotatably connected to the brackets 210, and the thimble can rotate in the direction between the opening 100 facing the housing 10 and the fixed support 20. In this embodiment: The thimble includes a needle tip 211 and a needle base 212, the needle tip 211 is connected to the needle base 212, a rotating shaft 213 is connected between the pair of brackets 210, and the needle base 212 is rotatably connected to the brackets 210 through the rotating shaft 213.

[0055] When the catheter is supported on the support mechanism, one orifice of the four-way pipe 50 of the catheter is inserted on the needle tip 211 of the thimble, and the pipe body 51 of the catheter is supported in the V-shaped groove 200 of the fixed support 20.

[0056] In an implementation manner of this embodiment: A notch 101 is formed on the housing 10, the notch 101 communicates with the opening 100, the notch 101, the fixed support 20 and the thimble are located on a straight line, that is, the catheter can be supported on these three at the same time. In this embodiment: The notch 101 is also V-shaped, and the V-shaped notch 101 and the fixed support 20 cooperate to prevent the protruding part of the pipe body 51 of the catheter from being displaced, and better position while supporting, and the V-shaped notch 101 of the housing 10 has the same shape as the V-shaped groove 200 of the fixed support 20 and is in close contact with each other. Due to the different lengths of the catheters, the pipe body 51 of the longer catheter can extend out of the housing 10 from the notch 101 on the housing 10 and is also supported at the notch 101.

[0057] Such as Figure 6a 、 6b As shown: The lamp head mechanism 3 is arranged inside the housing 10 and is located on at least one side of the curing area 22, and the distance and / or angle of the lamp head mechanism 3 relative to the curing area 22 is adjustable. In this embodiment: The lamp head mechanism 3 is arranged on both sides of the curing area 22 to achieve synchronous curing on both sides, improving the curing efficiency and quality of the catheter.

[0058] The lamp head mechanism 3 includes a chassis 30, a frame 31 and a plurality of lamp heads 32. The chassis 30 is connected to the bottom of the housing 10, the frame 31 is connected to the chassis 30, and the plurality of lamp heads 32 are connected to the frame 31.

[0059] In this embodiment: The chassis 30 can move in the direction of approaching or departing from the curing area 22, and / or the frame 31 can rotate relative to the chassis 30 in the up and down directions, and / or the distance between two adjacent lamp heads 32 is adjustable, so that the lamp head mechanism 3 can be independently or cooperatively adjusted in terms of the irradiation length range, irradiation width range, and irradiation distance to meet different adhesive curing requirements.

[0060] In one embodiment of the present embodiment: a linear adjustment hole 300 is provided on one of the chassis 30 and the bottom of the housing 10, and a connection hole is provided on the other of the chassis 30 and the bottom of the housing 10. The linear adjustment hole 300 and the connection hole are adjustably connected. In the figure: the linear adjustment hole 300 is a linear adjustment hole. The linear adjustment hole 300 of the present embodiment is provided at the bottom of the L-shaped chassis 30. By adjusting the fixed positions of the connection hole and the linear adjustment hole 300, the distance between the double-sided lamp head mechanism 3 and the curing area 22 can be adjusted.

[0061] In one embodiment of the present embodiment: an arc adjustment hole 301 is provided on one of the chassis 30 and the frame 31, and a connection hole is provided on the other of the chassis 30 and the frame 31. The arc adjustment hole 301 and the connection hole are adjustably connected. The arc adjustment hole 301 of the present embodiment is provided at the upper part of the L-shaped chassis 30. By adjusting the fixed positions of the connection hole and the arc adjustment hole 301, the tilt angle of the lamp head 32 on the frame 31 can be adjusted, as Figure 7 、 8 shown.

[0062] In the present embodiment, one lamp head 32 passes through the upper part of the chassis 30 and the frame 31 at the same time to form a rotating shaft for the frame 31 to rotate relative to the chassis 30. The frame 31 rotates around the lamp head 32 to adjust the tilt angle; the remaining lamp heads 32 are distributed on both sides of the lamp head 32.

[0063] In one embodiment of the present embodiment: a strip-shaped adjustment hole 310 is provided on the frame 31, and a connection hole is provided on the lamp head 32. The strip-shaped adjustment hole 310 of the frame 31 and the connection hole of the lamp head 32 are adjustably connected. In the figure: the strip-shaped adjustment hole 310 is a straight strip-shaped adjustment hole. By adjusting the fixed positions of the connection hole and the strip-shaped adjustment hole 310, the distance between two adjacent lamp heads 32 can be adjusted.

[0064] The light source system is an ultraviolet light source 4, and the ultraviolet light source 4 is connected to the lamp head 32 through a cable 40.

[0065] In one embodiment of the present embodiment: a wire hole 102 is provided on the housing 10, and the cable 40 is connected to the lamp head 32 through the wire hole 102, which is convenient for the light transmission between the ultraviolet light source 4 and the lamp head 32. In addition, a wiring area for the cable 40 is formed around the inside of the housing 10, and part of the wiring area is shielded by a baffle 12 to avoid operating errors.

[0066] The following specifically introduces the use process of the present embodiment:

[0067] The sliding cover 11 opens the opening 100 of the housing 10, exposing the support mechanism from the opening 100. Rotate the needle 211 upward so that the needle 211 faces the opening 100. Insert one nozzle of the four-way pipe 50 of the catheter into the needle 211. Rotate the needle 211 downward so that the pipe body 51 of the catheter is simultaneously supported in the V-shaped groove 200 of the fixed support 20 and the V-shaped notch 101 of the housing 1, completing the fixation of the catheter. Of course, if the catheter is not long enough, the pipe body 51 of the catheter can also be supported only in the V-shaped groove 200 of the fixed support 20. The sliding cover 11 closes the opening 100 of the housing 10, turns on the ultraviolet light source 4, and the ultraviolet light irradiates and cures the catheter through the lamp head 32. After the curing is completed, the catheter can be taken out.
