Description

Technical Field

[0001] This invention relates to the field of automated mechanical equipment, and more specifically to an automated assembly device and method for latex urinary catheters. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, a balloon near the tip of the catheter secures it in the bladder, preventing it from easily falling out. The drainage tube is connected to a urine bag to collect urine. Urinary catheters can be classified according to their lumen type as single-lumen catheters, double-lumen catheters, triple-lumen catheters, and double-balloon quadruple-lumen catheters.

[0003] Currently, for traditional multi-lumen urinary catheters, which are catheters with both a urination port and an injection port, after the multi-lumen urinary catheter is molded, it needs to be cut to create the urination port and injection port. Then, a rubber stopper needs to be inserted into the injection port, and a rubber sleeve needs to be fitted over the injection port. The traditional method for processing and assembling multi-lumen urinary catheters is to have operators manually process them on an assembly line. This easily leads to a huge workload for operators, low production efficiency, and long-term, large-scale production can also cause operators to lose concentration, thus making it impossible to consistently guarantee the assembly quality of multi-lumen urinary catheters. Summary of the Invention

[0004] The purpose of this invention is to provide an automated assembly device and method for latex urinary catheters, which can realize the automated processing and assembly of latex urinary catheters, and ultimately directly obtain the actual finished product of latex urinary catheters without manual assembly, thereby reducing the workload of operators and improving the production efficiency of latex urinary catheters.

[0037] The present invention also provides an automatic assembly method for latex urinary catheters, applicable to the automatic assembly equipment for the latex urinary catheters, comprising the following steps:

[0038] Step 1: Assemble the latex catheter onto the fixture corresponding to the tooling plate assembly.

[0039] Place the tooling plate assembly with the latex catheter assembled onto the double-speed chain conveyor line;

[0040] Step 2: The tooling plate assembly moves to the pipe cutting assembly via the double-speed chain conveyor, and the lifting mechanism lifts the tooling plate assembly to the pipe cutting station;

[0041] Step 3: The first catheter alignment mechanism clamps the latex catheter located on the tooling plate assembly, thereby aligning the multiple branches of the latex catheter. The first X-axis moving mechanism controls the cutting blade to move towards the cutting station. The cutting blade cuts the multiple branches of the latex catheter, and after cutting, the catheter residue is obtained. The ends of the multiple branches of the latex catheter are respectively formed into injection ports and urination ports. Then, the first X-axis moving mechanism controls the cutting blade to move above the unloading slide, and transfers the catheter residue into the unloading slide, completing the cutting of the latex catheter.

[0042] Step 4: The first catheter positioning mechanism releases the latex catheter located on the tooling plate assembly. The lifting mechanism drives the tooling plate assembly to descend back to the position of the double-speed chain conveyor. The tooling plate assembly moves to the rubber stopper installation assembly via the double-speed chain conveyor. The lifting mechanism lifts the tooling plate assembly to the rubber stopper installation position.

[0043] Step 5: The second catheter alignment mechanism clamps the latex catheter located on the tooling plate assembly, thereby aligning the multiple branches of the latex catheter. The first vibration feeding mechanism feeds the rubber plug into the feeding trough through its outlet end. The first XZ axis moving mechanism drives the needle to insert into the feeding trough and remove the rubber plug from the feeding trough. Then, the needle carrying the rubber plug moves to the container for placing glue, so that the rubber plug is coated with glue. After being coated with glue, the rubber plug moves to the top of the injection branch of the latex catheter and is pressed into the injection branch of the latex catheter. The first XZ axis moving mechanism drives the needle to return to its original position and wait, completing the rubber plug installation of the latex catheter.

[0044] Step Six: The second catheter positioning mechanism releases the latex catheter located on the tooling plate assembly. The lifting mechanism drives the tooling plate assembly to descend back to the position of the double-speed chain conveyor. The tooling plate assembly moves to the rubber sleeve installation assembly via the double-speed chain conveyor. The lifting mechanism lifts the tooling plate assembly to the rubber sleeve installation position.

[0045] Step 7: The third catheter alignment mechanism clamps the latex catheter located on the tooling plate assembly, aligning the multiple branches of the latex catheter. The second X-axis transfer mechanism moves the feeding and transferring section to the discharge end of the second vibrating feeding mechanism. The second vibrating feeding mechanism transfers the rubber sleeve through its discharge end to the feeding and transferring section. Then, the second X-axis transfer mechanism moves the feeding and transferring section to the operable range of the first transfer mechanism. The first transfer mechanism transfers the rubber sleeve at the feeding and transferring section to the first rubber sleeve expansion mechanism. The first rubber sleeve expansion mechanism... The rubber sleeve is expanded and fixed. The feeding and conveying part returns to the discharge end of the second vibrating feeding mechanism to receive the next batch of rubber sleeves and wait for transfer. The first transfer mechanism takes the rubber sleeve from the first rubber sleeve expansion mechanism and then transfers it to the second rubber sleeve expansion mechanism. While the first transfer mechanism transfers the next batch of rubber sleeves, the second rubber sleeve expansion mechanism expands and fixes the rubber sleeve. The second transfer mechanism takes the rubber sleeve from the second rubber sleeve expansion mechanism and puts the rubber sleeve onto the outer wall of the injection manifold of the latex catheter to complete the rubber sleeve installation of the latex catheter.

[0046] Step 8: The third catheter positioning mechanism releases the latex catheter located on the tooling plate assembly. The lifting mechanism drives the tooling plate assembly to descend back to the position of the double-speed chain conveyor line. The tooling plate assembly moves to the air injection detection assembly via the double-speed chain conveyor line. The lifting mechanism lifts the tooling plate assembly to the air injection detection station.

[0047] Step Nine: The fourth catheter alignment mechanism clamps the latex catheter located on the tooling plate assembly, aligning multiple branches of the latex catheter. The second XZ axis moving mechanism controls multiple air injection mechanisms to simultaneously insert into the injection and drainage branches of the latex catheter. The main lumen clamping mechanism clamps and blocks the main tube of the latex catheter. The air injection mechanisms fill the lumen with gas into the injection and drainage branches of the latex catheter. The connection between the injection and drainage branches is checked. If they are not connected, the latex catheter is qualified; if they are connected, it is unqualified. The main lumen clamping mechanism releases the main tube of the latex catheter. The second XZ axis moving mechanism controls the air injection mechanisms to leave the injection and drainage branches of the latex catheter, completing the air injection test of the latex catheter.

[0048] Step 10: The fourth catheter positioning mechanism releases the latex catheter located on the tooling plate assembly. The lifting mechanism drives the tooling plate assembly to descend back to the position of the double-speed chain conveyor. The tooling plate assembly moves to the unloading and collection assembly via the double-speed chain conveyor. The lifting mechanism lifts the tooling plate assembly to the unloading and collection station.

[0049] Step 11: The third X-axis moving mechanism controls the first catheter clamping mechanism to move towards the unloading and collection station. The first catheter clamping mechanism clamps the latex catheter. The third X-axis moving mechanism drives the first catheter clamping mechanism to remove the latex catheter from the tooling fixture. The lifting mechanism descends and returns to the position of the double-speed chain conveyor. The empty tooling plate assembly is recovered via the double-speed chain conveyor. Then, the third X-axis moving mechanism drives the first catheter clamping mechanism to move towards the second catheter clamping mechanism. The second catheter clamping mechanism receives and clamps the latex catheter. The first catheter clamping mechanism releases the latex catheter and returns to its original position. The rotating mechanism drives the second catheter clamping mechanism to flip so that the latex catheter flips to the position facing the conveyor belt of the belt conveyor. The second catheter clamping mechanism releases the latex catheter. Under the action of gravity, the latex catheter falls freely onto the conveyor belt of the belt conveyor. The belt conveyor transfers and recovers the processed latex catheter, completing the unloading and collection of the latex catheter.

[0050] The beneficial effects of this invention are:

[0051] 1. This equipment provides a tooling plate conveying assembly for fixed assembly and automatic conveying of latex catheters. It can sequentially move the latex catheters to the tube cutting assembly, rubber stopper installation assembly, rubber sleeve installation assembly, air injection detection assembly, and unloading and collection assembly, and then automatically perform tube cutting, rubber stopper installation, rubber sleeve installation, air injection detection, and unloading and collection in a production line.

[0052] 2. This equipment provides a tube cutting assembly that can automatically cut latex catheters, cutting the branch sections of the latex catheter that has just been molded into injection and drainage branches, and can automatically collect the remaining tubing material cut from the latex catheter.

[0053] 3. This equipment provides a rubber stopper installation assembly and a rubber sleeve installation assembly. The rubber stopper installation assembly can automatically install the rubber stopper in the corresponding injection manifold of the latex catheter, and the rubber sleeve installation assembly can automatically install the rubber sleeve at the corresponding injection manifold of the latex catheter, with automatic and precise assembly capabilities.

[0054] 4. This equipment provides an air injection detection assembly, which can inject gas into the injection and urination branches of the latex catheter, filling both branches completely. If both branches expand due to the gas injection, it indicates that the rubber stopper installation meets the product manufacturing standards. If neither branch shows expansion, it indicates that the rubber stopper has not completely blocked the injection branch. If the injection and urination branches are interconnected and gas leaks out, it indicates that the latex catheter does not meet the product manufacturing standards. This equipment is designed to screen out latex catheters that do not meet the product manufacturing standards, ensuring the proper use of the finished latex catheters.

[0055] 5. This equipment provides an unloading and collection assembly, which can unload the processed and assembled latex catheters from the tooling plate conveying assembly and collect them centrally for processing, so that workers can collect the processed and assembled latex catheters in a unified manner.

[0056] 6. With the integrated tooling plate conveying assembly, pipe cutting assembly, rubber stopper installation assembly, rubber sleeve installation assembly, air injection detection assembly, and unloading collection assembly, this equipment can realize the automated processing and assembly of latex urinary catheters, ultimately directly obtaining the actual finished latex urinary catheters without manual assembly, reducing the workload of operators and improving the production efficiency of latex urinary catheters.

[0106] The working principle of this equipment is as follows: First, the latex catheter, freshly molded using a mold, is assembled onto the tooling fixture 1101 on the tooling plate assembly 1100. Then, the tooling plate assembly 1100 is placed on the upper double-speed chain conveyor 1001. The upper double-speed chain conveyor 1001 transports the tooling plate assembly 1100 to the position of the tube cutting assembly 2. The lifting cylinder 7100a drives the lifting plate 7200a to rise, and the lifting plate 7200a lifts the tooling plate assembly 1100 to the tube cutting station. The first clamping cylinder 2401 drives the first clamping part 2402 to move. The two first clamping parts 2402 clamp multiple branches of the latex catheter, thereby straightening the multiple branches of the latex catheter. The double-stroke cylinder 2301 extends... In one stroke, the displacement plate 2303 moves backward, which in turn drives the cutting blade 2200 to move backward via the displacement frame 2311 placed on the displacement plate 2303. The second stepper motor 2306 drives the transmission belt assembly 2307, which in turn drives the first lead screw 2310 to rotate. The first lead screw 2310 drives the displacement frame 2311 to move forward via the threaded tube 2312. The cutting blade 2200 cuts multiple branches of the latex catheter. After the multiple branches of the latex catheter are cut, the infusion branch and the urination branch of the latex catheter are obtained. The remaining tubing material cut from the latex catheter is placed on the surface of the cutting blade 2200. The first telescopic cylinder 2502 drives the push bar 2503 to move forward. The push bar 2503 pushes the residual material in the guide tube placed on the surface of the cutting blade 2200, preventing it from sticking to the cutting blade 2200. The double-stroke cylinder 2301 extends for another stroke, and the cutting blade 2200 moves backward to above the unloading slide 2100. The double-stroke cylinder 2301 retracts for one stroke, and the displacement plate 2303 moves forward. The second stepper motor 2306 drives the transmission belt assembly 2307, which in turn drives the first lead screw 2310 to rotate. The first lead screw 2310 drives the displacement frame 2311 to move backward through the threaded tube 2312, causing the cutting blade 2200 to move backward. Due to inertia, the residual material in the guide tube falls from the cutting blade 2200 onto the unloading slide 2100 and is discharged from the unloading slide 2100. The remaining catheter material is transferred to the recycling area. The displacement plate 2303 returns to the starting position and stands ready under the drive of the double-stroke cylinder 2301. The second stepper motor 2306 drives the transmission belt assembly 2307 again. The transmission belt assembly 2307 drives the first lead screw 2310 to rotate. The first lead screw 2310 drives the displacement frame 2311 to move through the threaded tube 2312 so that the cutting blade 2200 returns to the starting position and stands ready. The two first clamping parts 2402 release the latex catheter under the drive of the first clamping cylinder 2401. The lifting cylinder 7100a drives the lifting plate 7200a to descend, and the tooling plate assembly 1100 is lowered back to the upper double-speed chain conveyor 1001 to complete the cutting process of the latex catheter.

[0107] The upper-level double-speed chain conveyor 1001 transports the tooling plate assembly 1100 to the location of the rubber stopper installation assembly 3. The lifting cylinder 7100b drives the lifting plate 7200b to rise, and the lifting plate 7200b lifts the tooling plate assembly 1100 to the rubber stopper installation position. The second clamping cylinder 3701 drives the second clamping part 3702 to move. The two second clamping parts 3702 clamp multiple branches of the latex catheter, so that the multiple branches of the latex catheter are straightened. The first vibrating feeding mechanism 3200 transports the rubber stopper to the feeding groove 3301 of the rubber stopper feeding block 3300 through its discharge end. The rubber stopper is placed in the feeding groove 3301. It should be noted that during this process, the output end of the second telescopic cylinder 3302 drives the rubber stopper feeding block. 3300 moves reciprocally along the Y-axis to align the feeding trough 3301 with the discharge end of the first vibrating feeding mechanism 3200, enabling the feeding trough 3301 to receive the rubber plug from the first vibrating feeding mechanism 3200. Then, the rubber plug feeding block 3300 is driven back to its original position to ensure subsequent docking with the positioning sleeve 3802 and the insertion pin 3500. The third stepper motor 3603 drives the second lead screw 3604 to rotate, which in turn moves the first movable support 3605 backward, thus moving the positioning sleeve 3802 and the insertion pin 3500 above the feeding trough 3301. The second lifting cylinder 3801 drives the positioning sleeve 3802 to descend, inserting it into the upper... The material is placed in the feed trough 3301 and a single rubber stopper is inserted into it. Then, the first lifting cylinder 3606 drives the inserter 3500 to descend, and the inserter 3500 inserts into the rubber stopper in the positioning sleeve 3802. Then, the positioning sleeve 3802 and the inserter 3500 rise synchronously, and the inserter 3500 removes the rubber stopper from the feed trough 3301. The first moving support 3605 moves forward, so that the inserter 3500 carrying the rubber stopper moves above the receiving box 3400. The receiving box 3400 is used to hold glue. The positioning sleeve 3802 and the inserter 3500 descend synchronously. After the front end of the rubber stopper is covered with glue, it will rise and leave the receiving box 3400. The first moving support 3605 moves forward again, so that the positioning sleeve 3802 and the inserter 3500 move upward. The device 500 moves above the infusion port of the latex catheter. The second lifting cylinder 3801 drives the positioning sleeve 3802 to descend, which then inserts the infusion port of the latex catheter into it. The first lifting cylinder 3606 drives the insertion needle 3500 to descend, inserting a rubber stopper into the infusion port of the latex catheter. Then, driven by the first lifting cylinder 3606, the insertion needle 3500 withdraws from the infusion port of the latex catheter. The rubber stopper is then glued to the infusion port of the latex catheter. It should be noted that the positioning sleeve 3802 ensures that the infusion port of the latex catheter faces upwards to align with the rubber stopper at the insertion needle 3500. When the insertion needle 3500 moves the rubber stopper to the infusion port of the latex catheter...The aligning sleeve 3802 prevents the injection port of the latex catheter from becoming misaligned due to the downward pressure of the rubber stopper, ensuring accurate and smooth installation of the rubber stopper into the injection port of the latex catheter. The aligning sleeve 3802 and the insertion needle 3500 rise to their original positions, and the first moving support 3605 returns to its original position, ready for operation. Driven by the second clamping cylinder 3701, the two second clamping parts 3702 release the latex catheter. The lifting cylinder 7100b drives the lifting plate 7200b to descend, lowering the tooling plate assembly 1100 back to the upper double-speed chain conveyor 1001, completing the rubber stopper installation process of the latex catheter.

[0108] The upper-level double-speed chain conveyor 1001 transports the tooling plate assembly 1100 to the location of the rubber sleeve installation assembly 4. The lifting cylinder 7100c drives the lifting plate 7200c to rise, and the lifting plate 7200c lifts the tooling plate assembly 1100 to the rubber sleeve installation position. The third clamping cylinder 4801 drives the third clamping part 4802 to move. The two third clamping parts 4802 clamp multiple branches of the latex catheter, so that the multiple branches of the latex catheter are straightened. The third telescopic cylinder 4301 moves the feeding transfer part 4200 to the discharge pipe 4101 of the second vibrating feeding mechanism 4100 through the fixing part 4302. The feeding hole 4201 of the feeding transfer part 4200 faces upward to correspond to the opening of the discharge pipe 4101. The second vibrating... The feeding mechanism 4100 conveys the rubber sleeves to the placement hole 4201 through the discharge pipe 4101. The opening and closing door 4202 in the placement hole 4201 blocks and supports the rubber sleeves, allowing them to be placed inside the placement hole 4201. It should be noted that the discharge pipe 4101 is designed to convey the rubber sleeves outward one by one. When the rubber sleeves are placed in the placement hole 4201, the opening of the rubber sleeves can be aligned with the opening of the placement hole 4201. The third telescopic cylinder 4301 moves the feeding transfer part 4200 to the first rubber sleeve expansion mechanism 4400 through the fixing member 4302. The placement hole 4201 is located above the first expansion gripper 4402. The fourth telescopic cylinder 4601 drives the second moving support 4604 to move, so that the push rod 4 607 corresponds downward to the feeding hole 4201. The third lifting cylinder 4602 drives the push rod 4607 to move downward. The push rod 4607 inserts into the feeding hole 4201 and continuously pushes the rubber sleeve. The opening and closing door 4202 is pushed open under the pushing action of the push rod 4607, and the rubber sleeve is fitted into the first expanding claw 4402. The first expanding claw 4402 expands and fixes the rubber sleeve under the drive of the first claw cylinder 4401, so that the rubber sleeve remains on the first expanding claw 4402. Then the push rod 4607 withdraws from the feeding hole 4201, the opening and closing door 4202 automatically closes, re-seals the feeding hole 4201, and the feeding and conveying part 4200 returns to the discharge pipe 4101 of the second vibrating feeding mechanism 4100, ready to receive. For the next batch of rubber sleeves, the fourth telescopic cylinder 4601 drives the third movable support 4605 to move, so that the first transfer fixing claw 4608 is aligned downwards with the first expanding claw 4402. The fourth lifting cylinder 4603 drives the first transfer fixing claw 4608 to move downwards, inserting it into the rubber sleeve. The first claw cylinder 4401 drives the first expanding claw 4402 to retract, and the rubber sleeve automatically retracts and is fixed on the first transfer fixing claw 4608. The first transfer fixing claw 4608 rises, pulling the rubber sleeve out of the first expanding claw 4402. The fourth telescopic cylinder 4601 again drives the third movable support 4605 to move, so that the first transfer fixing claw 4608 is aligned downwards with the second expanding claw 4502.Driven by the fourth lifting cylinder 4603, the first transfer fixing claw 4608 inserts the rubber sleeve into the second expanding claw 4502. Driven by the second claw cylinder 4501, the second expanding claw 4502 expands and fixes the rubber sleeve. The first transfer fixing claw 4608 then retracts from the rubber sleeve, leaving it on the second expanding claw 4502. The push rod 4607 and the first transfer fixing claw 4608 return to above the first expanding claw 4402, transferring the next batch of rubber sleeves to it. Simultaneously, the fifth telescopic cylinder 47... 01 drives the fourth movable support 4704 to move, causing the second transfer fixing claw 4705 to align downwards with the second expanding claw 4502. The fifth lifting cylinder 4702 drives the second transfer fixing claw 4705 to move downwards, inserting it into the rubber sleeve. The second claw cylinder 4501 drives the second expanding claw 4502 to retract, automatically retracting and fixing the rubber sleeve onto the second transfer fixing claw 4705. The second transfer fixing claw 4705 then rises, pulling the rubber sleeve out of the second expanding claw 4502. The fifth telescopic cylinder 4701 then... The fourth movable support 4704 is moved, causing the second transfer fixing claw 4705 to align downwards with the infusion port of the latex catheter. The fifth lifting cylinder 4702 drives the second transfer fixing claw 4705 downwards, aligning the rubber sleeve with the infusion port of the latex catheter. The sixth lifting cylinder 4703 drives the push-out sleeve 4706 downwards, pushing the rubber sleeve off the second transfer fixing claw 4705 and inserting it onto the outer wall of the infusion port of the latex catheter. It is understood that the rubber sleeve is positioned on the second transfer fixing claw 4705. When the tube is in an expanded state, as the ejector sleeve 4706 pushes the rubber sleeve off the second transfer fixing claw 4705, the rubber sleeve will tighten onto the outer wall of the infusion branch of the latex catheter. Finally, the second transfer fixing claw 4705 returns and prepares to transfer the next batch of rubber sleeves. Driven by the third clamping cylinder 4801, the two third clamping parts 4802 release the latex catheter. The lifting cylinder 7100c drives the lifting plate 7200c to descend, lowering the tooling plate assembly 1100 back to the upper double-speed chain conveyor 1001, completing the rubber sleeve installation process of the latex catheter.

[0109] The upper-level double-speed chain conveyor 1001 transports the tooling plate assembly 1100 to the location of the air injection testing assembly 5. The lifting cylinder 7100d drives the lifting plate 7200d to rise, and the lifting plate 7200d lifts the tooling plate assembly 1100 to the air injection testing station. The fourth clamping cylinder 5301 drives one fourth clamping part 5302 to move towards another fourth clamping part 5302. The two fourth clamping parts 5302 clamp multiple branches of the latex catheter, thereby straightening the multiple branches of the latex catheter. The seventh telescopic cylinder 5401 drives... The clamping assembly 5402 clamps the main tube of the latex catheter, preventing vertical connection between the two sections. The seventh lifting cylinder 5202, via the sixth telescopic cylinder 5203, drives the air injection mechanism 5100 to move up and down along the Z-axis. The sixth telescopic cylinder 5203, in turn, drives the air injection mechanism 5100 to move along the X-axis, thereby causing multiple air injection needles 5104 to be inserted downwards into the infusion and drainage sections of the latex catheter. The air injection cylinder 5102, through the gas pipeline assembly 5103 and the air injection needles 5104, injects air into the infusion and drainage sections of the latex catheter. Gas is injected into the urine branch tubing, filling both the lumen of the infusion branch and the urination branch tubing. If both tubing expands due to the gas injection, the rubber stopper installation meets product manufacturing standards. Conversely, if neither tubing shows expansion, the rubber stopper fails to completely block the infusion branch. If the infusion and urination branches are interconnected and gas leaks out, the latex catheter does not meet product manufacturing standards and requires further processing before being removed from the finished product. The gas injection mechanism 5100 completes the gas injection process for the latex catheter. After the urinary catheter is filled with gas, the air injection needle 5104 is driven by the second XZ axis moving mechanism 5200 to exit from the injection and drainage pipes of the latex urinary catheter. The seventh telescopic cylinder 5401 drives the clamping assembly 5402 to release the latex urinary catheter. The fourth clamping part 5302 is driven by the fourth clamping cylinder 5301 to release the latex urinary catheter. The lifting cylinder 7100d drives the lifting plate 7200d to descend, and the tooling plate assembly 1100 is lowered back to the upper double-speed chain conveyor 1001, completing the air injection detection process of the latex urinary catheter.

[0110] The upper-level high-speed chain conveyor transports the tooling plate assembly 1100 to the location of the unloading and collection assembly 6. The eighth telescopic cylinder 6301 drives the fifth movable support 6302 to move, causing the first catheter clamping mechanism 6200 to move above the latex catheter. The lifting cylinder 7100e drives the lifting plate 7200e to rise, and the lifting plate 7200e lifts the tooling plate assembly 1100 to the unloading and collection position, placing the latex catheter in the middle position between the movable clamping plate 6202 and the fixed clamping plate 6201. The first clamping cylinder 6203 drives the movable clamping plate 6202 to move towards the fixed clamping plate 6201. The movable clamping plate 6202 and the fixed clamping plate 6201 clamp the latex catheter. Then, driven by the eighth telescopic cylinder 6301, the latex catheter is removed from the tooling fixture 1101 and moved to the clamping jaws. 6401, the second clamping cylinder 6402 drives the clamping jaws 6401 to clamp the latex catheter. The moving clamping plate 6202 releases the latex catheter and returns to its original position. The rotating motor 6501 drives the rotating shaft 6502 to rotate. The rotating shaft 6502 drives the rotating support 6503 to flip, thereby causing the clamping jaws 6401 to flip towards the conveyor belt of the belt conveyor 6100. The clamping jaws 6401 release the latex catheter, and the latex catheter falls onto the conveyor belt of the belt conveyor 6100 under the action of gravity. The belt conveyor 6100 collects the processed latex catheters. The lifting cylinder 7100e drives the lifting plate 7200e to descend, lowering the empty tooling plate assembly 1100 back to the upper double-speed chain conveyor 1001, completing the unloading and collection of the latex catheters.

[0111] It should be noted that the vertical baffle 6101 is used to sort the latex catheters carried by different tooling plate assemblies 1100 after processing for subsequent quantity counting and packaging. The unloading slide plate 6600 facilitates the sliding of the falling latex catheters into the space between the two vertical baffles 6101, ensuring that the latex catheters fall smoothly onto the belt conveyor 6100 and preventing the latex catheters from being placed in a scattered manner.

[0112] It should be noted that the empty tooling plate assembly 1100 will move to the output end of the upper double-speed chain conveyor 1001, and then sequentially return to the input end of the upper double-speed chain conveyor 1001 via the first elevator 1003, the lower double-speed chain conveyor 1002, and the second elevator 1004, so that the operator can assemble a new latex catheter that needs to be processed. During the process of the tooling plate assembly 1100 moving from the upper double-speed chain conveyor 1001 to the second elevator 1004 or from the lower double-speed chain conveyor 1002 to the first elevator 1003, one side of the support panel 1012 of the corresponding lifting docking platform 1006 will be lifted by the output end of the angle adjusting cylinder 1011. When the tooling plate assembly 1100 enters the lifting docking platform 1006 of the first elevator 1003 or the second elevator 1004, it is in a downward slope state. At this time, the tooling plate assembly 1100... The center of gravity of the tooling plate assembly 1100 shifts, and it automatically slides into the lifting docking platform 1006 of the first elevator 1003 or the second elevator 1004. Similarly, during the process of the tooling plate assembly 1100 moving from the first elevator 1003 to the upper double-speed chain conveyor 1001 or from the second elevator 1004 to the lower double-speed chain conveyor 1002, one side of the support panel 1012 of the corresponding lifting docking platform 1006 will be lowered by the output end of the angle adjustment cylinder 1011. When the tooling plate assembly 1100 enters the upper double-speed chain conveyor 1001 or the lower double-speed chain conveyor 1002, it is in a downhill state. At this time, the center of gravity of the tooling plate assembly 1100 shifts, and it automatically slides into the upper double-speed chain conveyor 1001 or the lower double-speed chain conveyor 1002, forming a double-speed chain conveyor line for cyclic conveying, and thus forming an automated assembly production line for mass latex catheters.

[0113] The present invention also provides an automatic assembly method for latex urinary catheters, applicable to the automatic assembly equipment for the latex urinary catheters, comprising the following steps:

[0114] Step 1: Assemble the latex catheter onto the tooling fixture 1101 corresponding to the tooling plate assembly 1100, and place the tooling plate assembly 1100 with the latex catheter assembled onto the double speed chain conveyor line 1000.

[0115] Step 2: The tooling plate assembly 1100 moves to the pipe cutting assembly 2 via the double-speed chain conveyor 1000, and the lifting mechanism 7a lifts the tooling plate assembly 1100 to the pipe cutting station;

[0116] Step 3: The first catheter alignment mechanism 2400 clamps the latex catheter located on the tooling plate assembly 1100, thereby aligning the multiple branches of the latex catheter. The first X-axis moving mechanism 2300 controls the cutting blade 2200 to move towards the cutting station. The cutting blade 2200 cuts the multiple branches of the latex catheter, and after cutting, the catheter residue is obtained. The ends of the multiple branches of the latex catheter are respectively formed into injection ports and urination ports. Then, the first X-axis moving mechanism 2300 controls the cutting blade 2200 to move above the unloading slide 2100 and transfer the catheter residue into the unloading slide 2100, thus completing the cutting of the latex catheter.

[0117] Step 4: The first catheter positioning mechanism 2400 releases the latex catheter located on the tooling plate assembly 1100. The lifting mechanism 7a drives the tooling plate assembly 1100 to descend back to the position of the double-speed chain conveyor 1000. The tooling plate assembly 1100 moves to the rubber stopper installation assembly 3 via the double-speed chain conveyor 1000. The lifting mechanism 7b lifts the tooling plate assembly 1100 to the rubber stopper installation position.

[0118] Step 5: The second catheter alignment mechanism 3700 clamps the latex catheter located on the tooling plate assembly 1100, thereby aligning the multiple branches of the latex catheter. The first vibration feeding mechanism 3200 feeds the rubber plug into the feeding trough 3301 through its discharge end. The first XZ axis moving mechanism 3600 drives the insertion pin 3500 to insert into the feeding trough 3301, removing the rubber plug from the feeding trough 3301. Then, the insertion pin 3500 carrying the rubber plug moves to the container 3400 for placing glue, so that the rubber plug is coated with glue. After being coated with glue, the rubber plug moves to the top of the injection branch of the latex catheter and is pressed into the injection branch of the latex catheter. The first XZ axis moving mechanism 3600 drives the insertion pin 3500 to return to its original position for standby, completing the rubber plug installation of the latex catheter.

[0119] Step Six: The second catheter positioning mechanism 3700 releases the latex catheter located on the tooling plate assembly 1100. The lifting mechanism 7b drives the tooling plate assembly 1100 to descend back to the position of the double-speed chain conveyor 1000. The tooling plate assembly 1100 moves to the rubber sleeve installation assembly 4 via the double-speed chain conveyor 1000. The lifting mechanism 7c lifts the tooling plate assembly 1100 to the rubber sleeve installation position.

[0120] Step 7: The third catheter alignment mechanism 4800 clamps the latex catheter located on the tooling plate assembly 1100, thereby aligning the multiple branches of the latex catheter. The second X-axis transfer mechanism moves the feeding transfer section 4200 to the discharge end of the second vibrating feeding mechanism 4100. The second vibrating feeding mechanism 4100 transfers the rubber sleeve through its discharge end to the feeding transfer section 4200. Then, the second X-axis transfer mechanism moves the feeding transfer section 4200 to the operable range of the first transfer mechanism 4600. The first transfer mechanism 4600 transfers the rubber sleeve at the feeding transfer section 4200 to the first rubber sleeve expansion mechanism 4400. The first transfer mechanism 4400 expands and fixes the rubber sleeve, and the feeding and conveying unit 4200 returns to the discharge end of the second vibrating feeding mechanism 4100 to receive the next batch of rubber sleeves and wait for transfer. The first transfer mechanism 4600 takes the rubber sleeve from the first rubber sleeve expansion mechanism 4400 and then transfers it to the second rubber sleeve expansion mechanism 4500. While the first transfer mechanism 4600 transfers the next batch of rubber sleeves, the second rubber sleeve expansion mechanism 4500 expands and fixes the rubber sleeve. The second transfer mechanism 4700 takes the rubber sleeve from the second rubber sleeve expansion mechanism 4500 and puts the rubber sleeve onto the outer wall of the infusion branch of the latex catheter, completing the rubber sleeve installation of the latex catheter.

[0121] Step 8: The third catheter positioning mechanism 4800 releases the latex catheter located on the tooling plate assembly 1100. The lifting mechanism 7c drives the tooling plate assembly 1100 to descend back to the position of the double-speed chain conveyor line 1000. The tooling plate assembly 1100 moves to the air injection detection assembly 5 via the double-speed chain conveyor line 1000. The lifting mechanism 7d lifts the tooling plate assembly 1100 to the air injection detection station.

[0122] Step Nine: The fourth catheter alignment mechanism 5300 clamps the latex catheter located on the tooling plate assembly 1100, thereby aligning multiple branches of the latex catheter. The second XZ axis moving mechanism 5200 controls multiple air injection mechanisms 5100 to be simultaneously inserted into the injection and drainage branches of the latex catheter. The main lumen clamping mechanism 5400 clamps and blocks the main tube of the latex catheter. The air injection mechanism 5100 fills the lumen of the injection and drainage branches of the latex catheter with gas. The connection between the injection and drainage branches is checked. If they are not connected, the latex catheter is qualified. If they are connected, the latex catheter is unqualified. The main lumen clamping mechanism 5400 releases the main tube of the latex catheter. The second XZ axis moving mechanism 5200 controls the air injection mechanism 5100 to leave the injection and drainage branches of the latex catheter, completing the air injection test of the latex catheter.

[0123] Step 10: The fourth catheter positioning mechanism 5300 releases the latex catheter located on the tooling plate assembly 1100, the lifting mechanism 7d drives the tooling plate assembly 1100 to descend back to the position of the double-speed chain conveyor line 1000, the tooling plate assembly 1100 moves to the unloading and collection assembly 6 via the double-speed chain conveyor line 1000, and the lifting mechanism 7e lifts the tooling plate assembly 1100 to the unloading and collection station;

[0124] Step 11: The third X-axis moving mechanism 6300 controls the first catheter clamping mechanism 6200 to move towards the unloading and collection station. The first catheter clamping mechanism 6200 clamps the latex catheter. The third X-axis moving mechanism 6300 drives the first catheter clamping mechanism 6200 to remove the latex catheter from the tooling fixture 1101. The lifting mechanism 7e descends back to the position of the double-speed chain conveyor 1000. The empty tooling plate assembly 1100 is recovered via the double-speed chain conveyor 1000. Then, the third X-axis moving mechanism 6300 drives the first catheter clamping mechanism 6200 towards the second catheter clamping mechanism 64. The first catheter clamping mechanism 6200 moves in the direction of 00, and the second catheter clamping mechanism 6400 receives and clamps the latex catheter. The first catheter clamping mechanism 6200 releases the latex catheter and returns to its original position. The rotating mechanism 6500 drives the second catheter clamping mechanism 6400 to flip so that the latex catheter flips to the position facing the conveyor belt of the belt conveyor 6100. The second catheter clamping mechanism 6400 releases the latex catheter, and the latex catheter falls freely onto the conveyor belt of the belt conveyor 6100 under the action of gravity. The belt conveyor 6100 transfers and recycles the processed latex catheter, completing the unloading and collection of the latex catheter.

[0125] It should be noted that the motors and cylinders inside the tooling plate conveying assembly 1, pipe cutting assembly 2, rubber plug installation assembly 3, rubber sleeve installation assembly 4, air injection detection assembly 5, and unloading collection assembly 6 are all controlled by a computer. Their circuit connection relationships are not described in detail here, but this does not affect the integrity of this technical solution.
