DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Please refer to Figures 1-6 A semi-automatic equipment for assembling silica gel pipes of a pump type enteral nutrition device, comprising:

[0031] The base 01 and two sets of independent assembly units (work station one / work station two) symmetrically distributed.

[0032] The base 01 is a basic support platform of the whole equipment, used for bearing various main mechanism modules, ensuring the structural stability and the installation datum accuracy of various action components. The base 01 is a steel structure with high rigidity, and the surface is treated to be rust-proof and corrosion-resistant, so that the equipment can be operated in a clean workshop for a long time.

[0033] The assembly unit comprises the drop funnel base 05, the silica gel pipe base 06 and the pump pipe joint base 07 arranged on the base 01 respectively. The drop funnel base 05, the silica gel pipe base 06 and the pump pipe joint base 07 are provided with groove structures for positioning corresponding workpieces. The drop funnel base 05 is used for placing a drop funnel. The silica gel pipe base 06 is used for placing a silica gel pipe. The pump pipe joint base 07 is used for placing a pump pipe joint. The drop funnel base 05 is located on the left slide table cylinder 02 and is provided with a groove matched with the profile of the drop funnel, so that the drop funnel can be prevented from slipping or deviating during the movement and pressing of the cylinder.

[0034] The silica gel pipe base 06 is arranged at the central part of the base and serves as the connection core of the whole assembly process. The groove design of the silica gel pipe base 06 can ensure that the soft silica gel pipe can be stably fixed before being inflated.

[0035] The pump pipe joint base 07 is located above the right slide table cylinder 02 and is also provided with a special groove, so that the pump pipe joint can be stably positioned at the specified position and coaxially inserted with the silica gel pipe.

[0036] The pressing mechanism includes at least one set of rotary pressing cylinders 04 and drop funnel pressing covers 08, silica gel tube pressing blocks 09 and pump pipe joint pressing covers 010 driven by the rotary pressing cylinders 04, for pressing the drop funnel, silica gel tube and pump pipe joint on the corresponding base respectively during assembly;

[0037] The slide table cylinders 02 are provided in two sets and symmetrically arranged on the base 01. The slide table cylinders 02 are arranged in an L shape. The drop funnel base 05 is arranged on one of the slide table cylinders 02, and the pump pipe joint base 07 is arranged on the other slide table cylinder 02. The main function of the slide table cylinder 02 is to drive the drop funnel base 05 and the pump pipe joint base 07 to move synchronously towards the center to complete the sleeve connection with the expanded silica gel tube, and to reset away from the center after assembly is completed. The movement speed of the cylinder can be accurately controlled by a speed regulating valve to avoid impact on the workpiece caused by too fast movement.

[0038] The ventilation assembly includes double rod cylinders 03 and ventilation pipes 013 connected to the output end of the double rod cylinders 03. The double rod cylinders 03 are arranged in two sets and used to drive the ventilation pipes 013 to be inserted into the to-be-assembled end of the drop funnel and / or the to-be-assembled end of the pump pipe joint. The double rod cylinders 03 are arranged on the slide table cylinders 02. The ventilation pipes 013 are used to ventilate the silica gel tube to expand the inner hole thereof.

[0039] The ventilation pipes 013 are made of 316L medical-grade stainless steel and have a smooth and polished surface. The outer diameter is accurately controlled to be 0.1-0.2mm smaller than the inner diameter of the silica gel tube, so as to be easily inserted without damaging the silica gel tube. The end of the ventilation pipe 013 is designed in a smooth semispherical shape to avoid scratching the inner wall of the silica gel tube during insertion.

[0040] The ventilation pipes 013 are connected to the gas source interface 021. The gas pressure adjusting device 022 is arranged on the gas source interface 021 and used to introduce compressed air with a preset pressure into the silica gel tube. The pressure of the compressed air introduced into the silica gel tube can be accurately controlled. The pressure range can be adjusted between 0.05-0.3MPa to adapt to the expansion requirements of silica gel tubes of different specifications. The system is also equipped with a precision filter to ensure that the air introduced into the silica gel tube is clean and oil-free, meeting the production requirements of medical devices.

[0041] The application sets the ventilation assembly, including the double-rod air cylinder 03 and the ventilation pipe 013, and combines the gas source interface 021 and the air pressure adjusting device 022, so that the pre-set pressure of the compressed air can be injected into the inner cavity of the silica gel pipe before assembly, so that the lumen of the soft silica gel pipe is expanded, rounded and shaped, effectively overcoming the problems of diameter contraction, deformation and difficult insertion of the silica gel pipe in the natural state. Significantly improve the smoothness and success rate of the insertion of the dropper and the pump pipe joint and the silica gel pipe, reduce the assembly risks such as pipe jamming, pipe breaking and loose connection. At the same time, the resilience of the silica gel pipe is quickly restored after the ventilation operation is completed, ensuring its tight covering of the connecting parts, further improving the sealing performance and mechanical firmness, and providing reliable protection for the safety of liquid delivery in medical instrument applications.

[0042] The rotary compression cylinder 04 has a rotary action of at least 90 degrees and performs a downward action after rotation to drive the dropper compression cover 08, the silica gel pipe compression block 09 and the pump pipe joint compression cover 010 to compress the corresponding workpieces.

[0043] The slide table cylinder 02 is used to drive the dropper on the dropper base 05 and the pump pipe joint on the pump pipe joint base 07 to move towards the center direction, complete the sleeve connection with the silica gel pipe, and move away from the center direction of the workpiece to reset.

[0044] It also includes a rotary compression cylinder base, and the rotary compression cylinder 04 is installed on the rotary compression cylinder base.

[0045] It also includes a pad block 012, which is arranged between the double-rod air cylinder 03 and the slide table cylinder 02.

[0046] The device includes a work station one and a work station two, which are structurally symmetrical and constitute a set of independent assembly units, and can simultaneously or alternately perform assembly work. The work station one and the work station two of the device are completely symmetrical and work independently, and have the following advantages:

[0047] Two work stations can simultaneously perform assembly work, directly doubling the production capacity of the device; the simultaneous work or alternating work mode can be flexibly selected according to production needs; when one work station is maintained, the other work station can continue to produce, reducing downtime; two work stations can simultaneously assemble products of different specifications, improving the adaptability of the device.

[0048] Work flow:

[0049] Preparation stage: the operator places the dropper, silica gel pipe and pump pipe joint in the corresponding grooves of the base. After the system detects that the workpieces are in place, the next step is automatically started.

[0050] Compression and fixation stage: the rotary compression cylinder 04 rotates 90 degrees, moves each compression component above the workpiece, and then performs a downward action to firmly fix each workpiece.

[0051] Ventilation expansion stage: double rod cylinder 03 drives ventilation pipe 013 inserted into silica gel pipe at both ends at the same time, 0.15MPa compressed air is introduced into silica gel pipe through air source interface 021, so that the inner hole of silica gel pipe is uniformly expanded by 20-30%, which creates favorable conditions for sleeve connection.

[0052] Assembly sleeve connection stage: slide table cylinder 02 drives drop funnel base 05 and pump pipe joint base 07 to move synchronously to the center direction, so that the connecting ends of the drop funnel and the pump pipe joint are inserted into the silica gel pipe in the expanded state respectively. The insertion depth is accurately controlled by the stroke of slide table cylinder 02, which ensures firm and beautiful connection.

[0053] Pressure release stage: after the sleeve connection is completed, the air source is cut off and the pressure in the silica gel pipe is released, so that the silica gel pipe returns to its original state and tightly wraps around the connecting ends of the drop funnel and the pump pipe joint, forming a stable connection.

[0054] Reset and take out stage: double rod cylinder 03 drives ventilation pipe 013 to exit, slide table cylinder 02 resets, and rotary compression cylinder 04 loosens the pressure and rotates to reset. The operator takes out the assembled product, completing an assembly cycle.

[0055] The entire assembly process can be completed within 8-10 seconds, which improves the efficiency by more than 300% compared with traditional manual assembly. The equipment can be set to automatic continuous working mode or single step debugging mode, which is convenient for production and maintenance.
