DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Refer to the attached Figure 1 -Attached Fig. 9 A blood perfusion device housing sealing welding device comprises a support platform 1, a turntable 2 is rotatably mounted on the top of the support platform 1, four positioning holes 3 are equidistantly penetrated in the circumferential direction of the upper surface of the turntable 2, a mesh plate 17 is fixedly mounted on the inner wall of each positioning hole 3 near the bottom thereof, the positions of the support platform 1 located at the four positioning holes 3 are sequentially set as a placement station 4, a welding station 5, a detection station 6 and a material taking station 7, a limiting mechanism is installed at the position of the turntable 2 near each positioning hole 3, a heat dissipation mechanism is installed at the bottom of the mesh plate 17, a stepper motor 23 is fixedly mounted at the bottom of the support platform 1, and the output end of the stepper motor 23 penetrates the upper surface of the support platform 1 and is fixedly mounted to the rotation center of the turntable 2.

[0021] In this embodiment, the limiting mechanism includes two slide grooves 8 symmetrically opened on the upper surface of the turntable 2 near the positioning hole 3, the inner walls of the two slide grooves 8 are slidably installed with a first clamping block 9 and a second clamping block 10, a synchronization component is installed between the first clamping block 9 and the second clamping block 10, and an extrusion component is installed between the second clamping block 10 and the support platform 1. The synchronization component includes a first rack 11 and a second rack 12 fixedly installed on the outer surface of the same side of the first clamping block 9 and the second clamping block 10, respectively. The upper surface of the turntable 2 near the first rack 11 and the second rack 12 is provided with a movable groove 16, and the movable groove 16 A synchronous gear 13 is rotatably installed on the bottom wall, and the synchronous gear 13 is arranged between the first rack 11 and the second rack 12, and the first rack 11 and the second rack 12 are both meshed with the synchronous gear 13. The extrusion assembly includes a guide column 15 fixedly installed on the outer surface of the second clamping block 10 away from the first clamping block 9. An arc-shaped pressure plate 19 is fixedly installed on the upper surface of the support platform 1 between the placement station 4 and the welding station 5. The end of the arc-shaped pressure plate 19 is a slope structure. A tension spring rod 14 is fixedly installed between the outer surface of the first clamping block 9 away from the second clamping block 10 and the inner wall of the slide groove 8.

[0022] When the turntable 2 rotates, the first clamping block 9 and the second clamping block 10 will be driven to rotate synchronously. When the guide column 15 installed on the outside of the second clamping block 10 abuts against the end of the arc pressure plate 19, since the end of the arc pressure plate 19 is a sloped structure, the arc pressure plate 19 can push the second clamping block 10 to the inside of the positioning hole 3 through the guide column 15. When the second clamping block 10 moves, the first clamping block 9 will be driven to move synchronously through the second rack 12, the synchronous gear 13 and the first rack 11, so that the first clamping block 9 and the second clamping block 10 can clamp and fix the middle cylinder of the blood perfusion device shell at the same time, so as to avoid the blood perfusion device shell from moving during the subsequent welding operation, which affects the welding effect.

[0023] In this embodiment, the heat dissipation mechanism includes a heat dissipation fan blade 20 rotatably mounted on the lower surface of the mesh plate 17, a transmission gear 21 is fixedly mounted on the rotation center of the heat dissipation fan blade 20, an incomplete gear ring 22 is fixedly mounted on the upper surface of the support platform 1, the transmission gear 21 intermittently meshes with the incomplete gear ring 22, and the locking tooth section of the incomplete gear ring 22 is arranged between the welding station 5 and the inspection station 6.

[0024] When in use, the turntable 2 is driven by the stepper motor 23 to continue to rotate 90 degrees, and the welded blood perfusion device shell is rotated to the inspection station 6 for subsequent sealing inspection operations; when the turntable 2 drives the heat dissipation fan blade 20 to rotate to the tooth segment of the incomplete tooth ring 22, the transmission gear 21 fixedly installed at the rotation center of the heat dissipation fan blade 20 will engage with the tooth segment of the incomplete tooth ring 22, so that the transmission gear 21 can drive the heat dissipation fan blade 20 to rotate, so that the heat dissipation fan blade 20 can blow air upward, and the blood perfusion device shell placed in the positioning hole 3 is cooled by air, and the cooling speed of the high temperature at the welding port of the blood perfusion device shell is accelerated, so that the welding port of the blood perfusion device shell can be cured faster, so as to ensure the strength, shape and sealing of the welded joint.

[0025] In this embodiment, a welding mechanism is installed on the upper surface of the support platform 1 near the welding station 5, and the welding mechanism includes a first cantilever plate 501 fixedly installed on the upper surface of the support platform 1, and a first electric telescopic rod 502 is fixedly installed on the top of the first cantilever plate 501. The telescopic end of the first electric telescopic rod 502 passes through the top of the first cantilever plate 501 and is fixedly installed with an ultrasonic welding head 503.

[0026] During the welding operation, the telescopic end of the first electric telescopic rod 502 drives the ultrasonic welding head 503 to move downward until it contacts the welding point of the hemoperfusion device shell, so that the ultrasonic welding head 503 performs sealing welding on the end cover and the middle tube of the hemoperfusion device shell.

[0027] In this embodiment, a detection mechanism is installed on the upper surface of the support platform 1 near the detection station 6, and the detection mechanism includes a second cantilever plate 601 fixedly installed on the upper surface of the support platform 1, and a second electric telescopic rod 606 is fixedly installed on the top of the second cantilever plate 601, and the telescopic end of the second electric telescopic rod 606 passes through the top of the second cantilever plate 601 and is fixedly installed with a hollow cover shell 602, and a sealing ring 603 is fixedly installed on the bottom end of the hollow cover shell 602, and an air inlet pipe 604 connected to the interior of the hollow cover shell 602 is fixedly installed on the outer surface of the hollow cover shell 602, and a barometer 605 is installed on the air inlet pipe 604, and a sealing gasket 18 is fixedly installed on the upper surface of the mesh plate 17 near its middle position, and the sealing gasket 18 is an inverted original cone structure, and the diameter of the sealing gasket 18 is smaller than the aperture of the positioning hole 3, so that the wind blown upward by the heat dissipation fan blades 20 flows through the gap between the sealing gasket 18 and the positioning hole 3 to perform air cooling and heat dissipation on the blood perfusion device housing.

[0028] When in use, the hollow cover 602 is driven downward by the telescopic end of the second electric telescopic rod 606, so that the sealing ring 603 installed at the bottom end of the hollow cover 602 abuts against the connection port at the top end of the blood perfusion device shell. At the same time, when the blood perfusion device shell is subjected to downward pressure, the connection port at its bottom end will abut against the sealing gasket 18 installed on the mesh plate 17, so that the sealing gasket 18 and the sealing ring 603 can block the connection ports at both ends of the blood perfusion device shell. At the same time, the external air pump injects a certain air pressure into the hollow cover 602 through the air inlet pipe 604, so that the injected air pressure can enter the inside of the blood perfusion device shell. After the air is pumped, the pressure is maintained for a certain period of time, and the pressure change of the air pressure inside the blood perfusion device shell is monitored by the air pressure meter 605. If the pressure remains unchanged, it means that the welding point of the blood perfusion device is well sealed; if the pressure drops, it means that there is a leak at the welding point of the blood perfusion device, and an alarm is sounded through the external alarm to remind the staff that the blood perfusion device is not well sealed.

[0029] A method for using a blood perfusion device housing sealing welding device comprises the following steps: S1: Place the hemoperfusion device housing with the end cap and the middle tube buckled together from the placement station 4 into the positioning hole 3 provided on the turntable 2, and drive the turntable 2 to rotate 90 degrees counterclockwise by the stepper motor 23, so that the turntable 2 drives the placed hemoperfusion device housing to rotate to the welding station 5; S2: The ultrasonic welding head 503 is driven downward by the telescopic end of the first electric telescopic rod 502 until it contacts the welding point of the hemoperfusion device housing, so that the ultrasonic welding head 503 performs sealing welding on the end cover and the middle tube of the hemoperfusion device housing; S3: After the welding is completed, the turntable 2 is driven by the stepper motor 23 to continue to rotate 90 degrees, and the welded blood perfusion device shell is rotated to the inspection station 6, and the blood perfusion device shell is inspected for sealing by the inspection mechanism; S4: After the detection is completed, the stepper motor 23 continues to drive the turntable 2 to rotate 90 degrees, so that the blood perfusion device that has been detected is rotated to the material taking station 7, and the staff takes the blood perfusion device that has been detected.

[0030] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when in use, the blood perfusion device housing with the end cap and the middle tube buckled together is placed from the placement station 4 into the positioning hole 3 provided on the turntable 2, and the bottom of the middle tube falls on the surface of the sealing gasket 18 on the mesh plate 17, so as to support the middle tube and provide a sealing effect during the subsequent sealing test (when the blood perfusion device housing with one end cap welded, the end of the welded end cap can be directly placed on the sealing gasket 18, so that when the blood perfusion device housing is tested for sealing again, the sealing gasket 18 can seal the welded end cap interface. The blood perfusion device housing in this placed state is still located inside the positioning hole 3, ensuring the clamping effect of the first clamping block 9 and the second clamping block 10 on the blood perfusion device housing). The turntable 2 is driven by the stepper motor 23 to rotate counterclockwise by 90 degrees, so that the turntable 2 drives the placed blood perfusion device shell to rotate to the welding station 5. When the turntable 2 rotates, it will drive the first clamping block 9 and the second clamping block 10 to rotate synchronously. When the guide column 15 installed on the outside of the second clamping block 10 abuts against the end of the arc-shaped pressure plate 19, since the end of the arc-shaped pressure plate 19 is a slope structure, the arc-shaped pressure plate 19 can push the second clamping block 10 to the inside of the positioning hole 3 through the guide column 15. When the second clamping block 10 moves, the first clamping block 9 will be driven to move synchronously through the second rack 12, the synchronous gear 13 and the first rack 11, so that the first clamping block 9 and the second clamping block 10 can clamp and fix the middle cylinder of the blood perfusion device shell at the same time, so as to avoid the blood perfusion device shell from moving during the subsequent welding operation, thereby affecting the welding effect.

[0031] During the welding operation, the ultrasonic welding head 503 is driven downward by the telescopic end of the first electric telescopic rod 502 until it contacts the welding point of the hemoperfusion device shell, so that the ultrasonic welding head 503 performs sealing welding on the end cover and the middle tube of the hemoperfusion device shell (the ultrasonic welding head 503 converts the high-frequency ultrasonic frequency signal into high-frequency mechanical vibration, so that the friction between the surface of the product to be welded and the molecules increases the temperature transmitted to the weld, thereby completing the welding of the product to be welded). After the welding is completed, the telescopic end of the first electric telescopic rod 502 drives the ultrasonic welding head 503 to rise and reset, completing the welding operation; After the welding is completed, the turntable 2 is driven by the stepper motor 23 to continue to rotate 90 degrees, and the welded blood perfusion device shell is rotated to the inspection station 6 for subsequent sealing inspection operations; when the turntable 2 drives the heat dissipation fan blade 20 to rotate to the tooth segment of the incomplete tooth ring 22, the transmission gear 21 fixedly installed at the rotation center of the heat dissipation fan blade 20 will mesh with the tooth segment of the incomplete tooth ring 22, so that the transmission gear 21 can drive the heat dissipation fan blade 20 to rotate, so that the heat dissipation fan blade 20 can blow air upward, and the blood perfusion device shell placed in the positioning hole 3 is cooled and dissipated, and the cooling speed of the high temperature at the welding port of the blood perfusion device shell is accelerated, so that the welding port of the blood perfusion device shell is cured faster, so as to ensure the strength, shape and sealing of the welded joint; When the sealing test is performed, the guide column 15 installed on the outer side of the second clamp block 10 is disengaged from the arc-shaped pressure plate 19, so that the first clamp block 9 and the second clamp block 10 are reset under the action of the tension spring rod 14 and the synchronization component, and the clamping of the blood perfusion device housing is released; the telescopic end of the second electric telescopic rod 606 drives the hollow cover 602 to move downward, so that the sealing ring 603 installed at the bottom end of the hollow cover 602 is abutted against the connecting port at the top end of the blood perfusion device housing. At the same time, when the blood perfusion device housing is subjected to downward pressure, the bottom end of the middle tube of the blood perfusion device housing will abut against the sealing pad 18 installed on the mesh plate 17. The sealing pad 18 and the sealing ring 603 can block the two end connection ports of the blood perfusion device housing. At the same time, the external air pump injects a certain air pressure into the hollow cover shell 602 through the air inlet pipe 604, so that the injected air pressure can enter the inside of the blood perfusion device housing. After the air is pumped, the pressure is maintained for a certain period of time. The pressure change of the air pressure inside the blood perfusion device housing is monitored by the air pressure meter 605. If the pressure remains unchanged, it means that the welding point of the blood perfusion device is well sealed; if the pressure drops, it means that there is a leak at the welding point of the blood perfusion device, and an alarm is sounded through the external alarm to remind the staff that the blood perfusion device is not well sealed. After the detection is completed, the stepper motor 23 continues to drive the turntable 2 to rotate 90 degrees, so that the blood perfusion device that has been tested is rotated to the material collection station 7, so that the staff can take the blood perfusion device that has been tested; after the material collection is completed, the turntable 2 continues to rotate 90 degrees and returns to the placement station to load the next blood perfusion device.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
