Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical equipment assembly, and particularly relates to an assembling device for a drip chamber. BACKGROUND

[0002] The drip chamber is a commonly used component in a blood dialysis extracorporeal circulation pipeline, and can be used for collecting gas generated in a treatment process to reduce the risk of gas entering the human body. The drip chamber comprises a drip chamber body, and a blood inlet and a blood outlet are arranged at two ends of the drip chamber body respectively. A cover body is arranged at the blood inlet end, and a filter screen is arranged inside the blood outlet end.

[0003] A drip chamber assembling machine is disclosed in Chinese Patent Application No. 201010179987X, which comprises a rotating disc mechanism, and a filter screen placing mechanism, a material placing mechanism, a filter screen pressing mechanism, a position adjusting mechanism, a glue sticking mechanism, and a bottom cover placing mechanism are sequentially arranged around the rotating disc mechanism. The filter screen placing mechanism places the filter screen on each working position of the rotating disc mechanism, the material placing mechanism places the drip chamber body on the filter screen, the filter screen pressing mechanism presses the filter screen and the drip chamber body, the position adjusting mechanism adjusts the angle of the drip chamber body, the glue sticking mechanism sticks glue on the drip chamber body, and the bottom cover placing mechanism places the bottom cover on the drip chamber body.

[0004] However, the above-mentioned scheme uses a disc mechanism as a conveying device, and other working mechanisms can only be arranged around the disc mechanism, which leads to crowding, and the size of the other working mechanisms cannot be increased. Each working mechanism can only assemble one drip chamber at a time, and the production efficiency still needs to be improved. In addition, the disc-shaped conveying mechanism causes the space in the center of the disc to be idle, and the space utilization rate is low. SUMMARY

[0005] In view of the problems in the prior art, the present application aims to solve the problems of small pipeline size, low production efficiency, and low space utilization rate in the prior art.

[0006] The purpose of the present application can be achieved by the following technical solutions:

[0007] The application discloses an assembling device for a drop chamber, which comprises an assembling jig, a circulating conveying line for conveying the assembling jig and a mounting rack group which is horizontally arranged above the circulating conveying line. The mounting rack group comprises a plurality of pairs of vertical columns which are arranged on both sides of the circulating conveying line, and a cross beam which is arranged between each pair of vertical columns and above the circulating conveying line. The assembling jig comprises a jig bottom plate, a row of drop chamber rods and a row of hollow filter screen push rods which are arranged on the jig bottom plate. The drop chamber rod comprises a main body and a guide part at the lower end of the main body. An upper feeding assembly, a pressing assembly, a material moving assembly and a cover assembling assembly are sequentially arranged on the mounting rack group along the advancing direction of the circulating conveying line. A translation glue adding assembly is further arranged below the material moving assembly and the cover assembling assembly. The upper feeding assembly, the material moving assembly and the cover assembling assembly are slidingly connected to the mounting rack group and can slide forward and backward perpendicularly to the circulating conveying line. The pressing assembly is fixedly connected to the mounting rack group and is arranged above the filter screen push rod.

[0008] The filter screen push rod is used for placing the filter screen. The filter screen is arranged in the hollow filter screen push rod, and the caliber of the filter screen is larger than that of the filter screen push rod. The filter screen is clamped at the top end of the filter screen push rod. The drop chamber rod is used for placing the drop chamber main body. When the drop chamber main body is sleeved outside the drop chamber rod, because the end of the drop chamber main body which is covered by the cover is not a regular cylinder, the end has an inclined arc surface. Therefore, the shape of the guide part of the drop chamber rod is matched with the covered end of the drop chamber main body. In the process of arranging the drop chamber main body, the guide positioning is automatically completed, so that all the drop chamber main bodies are arranged in the same direction. Therefore, an additional alignment mechanism is not needed, the process is simplified, and the cost is reduced.

[0009] The upper feeding assembly clamps the drop chamber main body on the drop chamber rod and sleeves the drop chamber main body on the filter screen push rod. Then, the drop chamber main body is conveyed to below the pressing assembly, the filter screen is pressed into the clamping groove in the drop chamber main body, and then the drop chamber main body is conveyed to below the material moving assembly. The material moving assembly clamps the drop chamber with the pressed filter screen into the translation glue adding assembly to add glue. The translation glue adding assembly translates the drop chamber to below the cover assembling assembly. The cover assembling assembly clamps the drop chamber to perform the cover assembling process and discharges the drop chamber. The whole assembling process is fully automated. The device layout is compact, the space utilization rate is high, and in the scheme, the working mechanisms can have a larger size without interfering with each other, so that the production efficiency of the assembly line is further improved.

The bottom end of the upper feeding lifting driving source is fixedly connected to the upper feeding lifting plate and can drive the upper feeding lifting plate to lift vertically. The upper feeding lifting plate is fixedly connected to a plurality of groups of upper feeding clamping finger assemblies.

[0011] The loading lifting drive source drives the loading clamping finger assembly to rise and fall, and the loading translation drive source drives the loading translation plate to drive the loading clamping finger assembly to move back and forth. The loading clamping finger assembly is used to clamp the drip chamber body, thereby realizing the movement and placement of the drip chamber body, and finally putting the drip chamber body on the filter push rod, so that the card slot in the drip chamber body and the filter are connected.

[0012] In the assembly equipment of the drip chamber, the pressing assembly includes a pressing base plate and several groups of pressing cylinders fixedly connected to the pressing base plate.

The cover mounting lifting cylinder drives the cover mounting clamp finger assembly to ascend and descend. The cover mounting clamp finger assembly is used to clamp the drop port chamber after the glue adding is completed, and then the drop port chamber is moved and covered. After the covering is completed, the drop port chamber is clamped and unloaded. The cover mounting assembly is the working mechanism with the longest stroke in the scheme, and the positioning requirement for the drop port chamber during covering is higher. Therefore, the structure of the cover mounting translation plate connected with the cover mounting translation rail at both ends is used to enhance the stability of the cover mounting assembly during movement, so as to avoid the change of the position angle of the drop port chamber during movement due to shaking, and affect the covering effect.

[0018] Further, the cover mounting clamp finger assembly comprises a cover mounting clamp finger, a clamp finger cylinder for driving the cover mounting clamp finger to open and close, and a top mounting cylinder.

The top of the top mounting cylinder is downwardly connected with a top mounting block. The top mounting block is horizontally arranged and extends into the top mounting channel. The top mounting cylinder drives the top mounting block to ascend and descend in the top mounting channel.

[0019] During covering, the cover mounting clamp finger clamps the drop port chamber. The blood outlet end of the drop port chamber protrudes from the open drop port chamber accommodating cavity. The top mounting cylinder drives the top mounting block to descend in the top mounting channel, and abuts against the blood outlet end of the drop port chamber to press the drop port chamber downward, so as to complete the assembly of the blood inlet end of the drop port chamber and the cover.
