Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment assembly, in particular to an assembly device for a drip chamber. Background Art

[0002] The drip chamber is a common component in hemodialysis extracorporeal circuits. It collects gases generated during treatment, reducing the risk of them entering the body. The drip chamber consists of a main body with a blood inlet and a blood outlet at either end. A cap is placed on the blood inlet, and a filter is placed inside the blood outlet.

[0003] The Chinese invention patent application number "201010179987X" discloses a drip chamber assembly machine, including a turntable mechanism, around which are arranged a filter placing mechanism for placing the filter on each station of the turntable mechanism, a material unloading mechanism for placing the drip chamber body on the filter, a filter pressing mechanism for pressing the drip chamber body and the filter, a positioning mechanism for adjusting the angle of the drip chamber body to be consistent, a gluing mechanism for removing the drip chamber body with adjusted position and gluing it, and a bottom cover mounting mechanism for mounting the glued drip chamber body on the bottom cover. The turntable mechanism drives the following operations in sequence: placing the filter, placing the drip chamber body, pressing the filter and the drip chamber body, adjusting the angle of the drip chamber body by the positioning mechanism, gluing and installing the bottom cover.

[0004] However, the above scheme uses a disc mechanism as a conveying device, and other working mechanisms can only revolve around the disc mechanism, resulting in congestion. The volume of other working mechanisms cannot be increased, and each working mechanism can only assemble one drip chamber each time it moves. Its production efficiency still needs to be improved, and the disc-shaped transport mechanism causes the space in the center of the disc to be idle, resulting in low space utilization. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to solve the problems of small volume, low production efficiency and low space utilization of the existing production line.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A drop chamber assembly device comprises an assembly jig, a circulating conveyor line for conveying the assembly jig, and a mounting frame group spanning above the circulating conveyor line, the mounting frame group comprising several pairs of columns arranged on both sides of the circulating conveyor line, each pair of columns being connected by a crossbeam, and the crossbeam being located above the circulating conveyor line; the assembly jig comprises a jig base plate, a row of drop chamber rods and a row of hollow filter push rods are provided on the jig base plate, the drop chamber rods comprising a main body and a guide portion at the lower end of the main body; a loading assembly, a pressing assembly, a material moving assembly and a capping assembly are sequentially provided on the mounting frame group along the direction of travel of the circulating conveyor line, a translational glue adding assembly is further provided below the material moving assembly and the capping assembly, the loading assembly, the material moving assembly and the capping assembly are slidably connected to the mounting frame group and can slide back and forth perpendicular to the circulating conveyor line, the pressing assembly is fixedly connected to the mounting frame group and is located above the filter push rod.

[0008] The filter push rod is used to place the filter, and the filter is placed in the hollow filter push rod. The diameter of the filter is larger than the diameter of the filter push rod, and the filter is stuck on the top of the filter push rod; the drip chamber rod is used to place the drip chamber body. When the drip chamber body is put on the outside of the drip chamber rod, because the end of the drip chamber body where the cover is installed is not a regular cylinder, but has an inclined arc surface, the shape of the guide part of the drip chamber rod fits with the cover end of the drip chamber body. During the installation process of the drip chamber body, the guide positioning is automatically completed so that all the drip chamber bodies are facing in one direction. There is no need to set up an additional positioning mechanism, which simplifies the process to achieve cost reduction and efficiency improvement.

[0009] The feeding component clamps the drip chamber body on the drip chamber rod and sets it on the filter push rod, and then transports it to the bottom of the clamping component to press the filter into the slot inside the drip chamber body, and then transports it to the bottom of the material moving component. The material moving component clamps the drip chamber with the pressed filter and puts it into the translational glue adding component for glue adding. The translational glue adding component moves the drip chamber horizontally to the bottom of the capping component. The capping component clamps the drip chamber for the capping process and unloading. The entire assembly process is fully automated, the equipment layout is compact, and the space utilization rate is high. Moreover, in this solution, each working mechanism can be set with a larger volume without interfering with each other, further improving the production efficiency of the assembly line.

[0010] In the assembly equipment of this drop mouth chamber, the loading assembly includes a loading base plate, a loading translation plate, a loading translation drive source, a loading lifting plate, a loading lifting drive source and a loading clamping finger assembly; a loading translation drive source and two loading translation rails are horizontally arranged on the loading base plate, and a loading translation block adapted to the loading translation rail is arranged on one side of the loading translation plate. The loading translation drive source can drive the loading translation plate to slide horizontally back and forth, and the other side of the loading translation plate is fixedly connected to the loading lifting drive source. The bottom end of the loading lifting drive source is fixedly connected to the loading lifting plate and can drive the loading lifting plate to rise and fall vertically. Several groups of loading clamping finger assemblies are fixedly connected to the lower bottom surface of the loading lifting plate.

[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 lower end of the pressing cylinder is fixedly connected to a pressing block and can drive the pressing block to rise and fall. The pressing block is provided with a pressing cavity.

[0013] The position of the clamping block is aligned with the position of the filter push rod. The clamping cylinder drives the clamping block to descend and press the drip chamber body downward. The filter is inserted into the slot inside the drip chamber body to complete the filter assembly. The clamping cavity on the clamping block is used to accommodate one end of the blood outlet of the drip chamber body. The shape fits the end of the blood outlet of the drip chamber body to avoid damage to the drip chamber body during clamping.

[0014] In the assembly equipment of this droplet chamber, the material moving assembly includes a material moving base plate, a material moving translation driving source horizontally fixed to the material moving base plate, and a material moving mounting frame slidably connected to the material moving base plate. The material moving translation driving source can drive the material moving mounting frame to slide horizontally back and forth. A material moving lifting cylinder is fixed on the material moving mounting frame. The rod head of the material moving lifting cylinder faces downward and is fixedly connected to the material moving lifting plate. Several groups of material moving finger assemblies are fixedly connected to the lower bottom surface of the material moving lifting plate.

[0015] The material transfer translation drive source drives the material transfer mounting frame to move the material transfer clamping finger assembly forward and backward, and the material transfer lifting cylinder drives the material transfer clamping finger assembly to rise and fall. The material transfer clamping finger assembly is used to clamp the drip chamber, move the drip chamber and place it in the translation glue adding assembly for glue adding.

[0016] In the assembly equipment of this dropper chamber, the cover assembly includes a cover base plate, two cover translation rails fixedly connected to the upper surface of the cover base plate in parallel, a cover translation drive source arranged between the two cover translation rails and a cover translation plate slidably connected to the two cover translation rails. The lower bottom surface of the cover translation plate is fixedly connected to the cover mounting plate, and a through translation channel is provided in the middle of the cover base plate. The cover mounting plate passes through the translation channel and moves back and forth in the translation channel. Several cover lifting cylinders are fixedly connected to the cover mounting plate, and the lower ends of the cover lifting cylinders are fixedly connected to the cover clamping finger assembly and can control the lifting and lowering of the cover clamping finger assembly.

[0017] The capping translation drive source drives the capping translation plate to drive the capping finger assembly to translate back and forth within the translation channel. The capping lifting cylinder drives the capping finger assembly to rise and fall. The capping finger assembly is used to clamp the drip chamber after the cap is filled with glue, move the drip chamber and install the cap. After the capping is completed, the drip chamber is clamped for unloading. The capping assembly is the working mechanism with the longest travel in this solution, and the positioning of the drip chamber is more demanding during capping. Therefore, the structure of connecting the capping translation rails at both ends of the capping translation plate enhances the stability of the capping assembly during movement, avoiding the change of position angle of the drip chamber due to shaking during movement, which affects the capping effect.

[0018] Furthermore, the capping finger assembly includes a capping finger, a finger cylinder for driving the capping finger to open and close, and a top-loading cylinder. The capping finger is provided with a drip chamber accommodating cavity and a top-loading channel. The upper end of the drip chamber accommodating cavity is open, and the top-loading channel is located at the upper part of the drip chamber accommodating cavity and passes through the capping finger from front to back; a cylinder fixing block is fixed on the side of the finger cylinder, and the top-loading cylinder is fixedly connected to the cylinder fixing block. The rod head of the top-loading cylinder faces downward and is fixedly connected to the top-loading block at the rod head. The top-loading block is horizontally arranged and extends into the top-loading channel. The top-loading cylinder drives the top-loading block to rise and fall in the top-loading channel.

[0019] When installing the cap, the capping clamping fingers clamp the drip chamber, and one end of the blood outlet of the drip chamber protrudes from the open drip chamber accommodating cavity. The top-loading cylinder drives the top-loading block to descend in the top-loading channel, conflicts with one end of the blood outlet of the drip chamber and presses the drip chamber downward, completing the assembly of one end of the blood inlet of the drip chamber and the lid. The structure is simple and compact, the capping effect is good and the efficiency is high, and there is no need to clamp the drip chamber too tightly to avoid damage to the drip chamber. When unloading, the capping clamping fingers are opened and the top-loading block descends to lightly push the drip chamber, helping the drip chamber to fall more accurately into the conveying fixture below when it is separated from the capping clamping fingers.

[0020] In the assembly equipment of this dropper chamber, the translational glue adding component includes a glue adding mounting frame, a glue adding translation driving source horizontally fixed to the glue adding mounting frame, and a glue adding mechanism slidably connected to the glue adding mounting frame. The glue adding translation driving source can drive the glue adding mechanism to translate left and right; the glue adding mechanism includes a glue adding translation plate and a glue storage box located on one side of the glue adding translation plate. A glue adding lifting cylinder is fixedly connected to the outer side of the glue adding translation plate. The rod head of the glue adding lifting cylinder is fixedly connected to the glue adding lifting plate and can drive the glue adding lifting plate to rise and fall. Several groups of glue clamping finger assemblies are fixedly connected to the glue adding lifting plate.

[0021] Furthermore, the glue adding clamping finger assembly includes a glue adding clamping finger and a glue adding clamping finger cylinder that drives the glue adding clamping finger to open and close. The glue adding clamping finger is "L" shaped, including a connecting part and a clamping part. The clamping part extends horizontally to the top of the glue storage box, and an arc-shaped clamping groove is provided at the front end of the clamping part.

[0022] The glue adding translation drive source drives the glue adding mounting frame to drive the glue adding clamping finger assembly to move left and right below the material moving assembly and the capping assembly. The glue adding clamping finger assembly is used to clamp and fix the drip chamber. The glue adding lifting cylinder drives the glue adding clamping finger assembly to rise and fall, and the blood inlet end of the drip chamber is placed in the glue storage box for glue adding. When clamping, the drip chamber falls into the arc-shaped clamping groove and fits with the inner wall of the clamping groove, making the clamping more stable. At the same time, it can also play a guiding and limiting role on the drip chamber to fix its position.

[0023] The assembly equipment of this droplet chamber also includes an in-place detection component, which is located parallel to the material transfer component. The in-place detection component includes a vertically arranged detection mounting plate, a detection translation plate slidably connected to the side of the detection mounting plate, and a detection translation cylinder fixedly connected to the other side of the detection mounting plate. The detection translation cylinder can drive the detection translation plate to translate back and forth; the outer end of the detection translation plate is fixedly connected to a detection lifting cylinder, the outer end of the detection lifting cylinder is fixedly connected to the detection lifting plate and can drive the detection lifting plate to rise and fall, and several groups of in-place sensing devices are fixedly connected to the detection lifting plate.

[0024] During processing, the detection translation cylinder drives the detection translation plate, which drives the in-place sensing device to translate above the filter push rod of the assembly fixture. The detection lifting cylinder drives the in-place sensing device to rise and fall to detect the in-place status of the drip chamber. The in-place detection component and the material transfer component are arranged side by side, one near the left side of the circulating conveyor line and the other near the right side of the circulating conveyor line. The in-place detection component first checks the in-place status of the drip chamber on the assembly fixture. After the test is completed, the in-place detection component retracts, and the material transfer component extends forward to clamp the drip chamber. The two components do not interfere with each other, and their positioning fully utilizes the space above the circulating conveyor line, resulting in a compact structure and high space utilization.

[0025] The assembly equipment of the drip chamber also includes a cover translation assembly, which is located below the cover installation assembly and on the side of the glue adding translation assembly. The cover translation assembly includes a cover translation bracket, a cover translation drive source fixedly connected to the cover translation bracket, and a cover jig slidably connected to the cover translation drive source. The cover translation drive source can drive the cover jig to translate left and right, and the cover jig is provided with a number of cover accommodating cavities.

[0026] One end of the cap translation assembly is located below the cap installation assembly and on the side of the glue adding translation assembly, and the other end is connected to the cap loading device. The cap loading device arranges the caps in the cap jig, and the cap translation assembly drives the jig to translate to the corresponding position of the cap installation assembly and assembles the cap to the blood inlet end of the drip chamber.

[0027] Compared with the prior art, the technical effects of the present invention are:

[0028] First, in this solution, the shape of the guide portion of the drip chamber rod fits the inclined surface of the cover end of the drip chamber body. During the installation of the drip chamber body, the guide positioning is automatically completed so that all the drip chamber bodies are facing in one direction. There is no need to set up an additional positioning mechanism, which simplifies the process and saves costs.

[0029] Second, the entire assembly process in this solution is fully automated, and the various working mechanisms are arranged along the circular conveyor line, which can be set up with a larger volume to increase work efficiency. The structural design of each working mechanism is simple and reasonable, achieving cost reduction and efficiency improvement.

[0030] Third, the various working mechanisms in this solution are compactly arranged, making full use of the space above and on both sides of the circulating conveyor line. The processing process is smooth and the various components will not interfere with each other and affect work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, the loading assembly 3, the material moving assembly 5 and the capping assembly 6 are slidably connected to the mounting frame group 2 and can slide back and forth perpendicular to the circulating conveyor line 1, the pressing assembly 5 is fixedly connected to the mounting frame group 3 and is located above the filter push rod 13.

[0045] As a preferred solution, Figure 2 As shown, the assembly jig 11 includes a jig base plate 111 , on which a row of drip chamber rods 112 and a row of hollow filter push rods 113 are provided. The drip chamber rods 112 include a main body 114 and a guide portion 115 at the lower end of the main body 114 .

The diameter of the filter is larger than the diameter of the filter push rod 113, and the filter is stuck at the top of the filter push rod 113; the drip chamber rod 112 is used to place the drip chamber body. When the drip chamber body is put on the outside of the drip chamber rod 112, because the end of the drip chamber body for covering is not a regular cylinder, but has an inclined arc surface, the shape of the guide part 115 of the drip chamber rod 112 fits the covering end of the drip chamber body. During the process of installing the drip chamber body, the guiding positioning is automatically completed so that all the drip chamber bodies are facing in one direction. There is no need to set up an additional positioning mechanism, which simplifies the process to achieve cost reduction and efficiency improvement.

The material moving translation drive source 52 can drive the material moving mounting frame 53 to slide horizontally back and forth. A material moving lifting cylinder 54 is fixed to the material moving mounting frame 53. The rod head of the material moving lifting cylinder 54 faces downward and is fixed to the material moving lifting plate 55. The lower bottom surface of the material moving lifting plate 55 is fixedly connected to a plurality of groups of material moving clamping finger assemblies 56. The material moving translation drive source 52 drives the material moving mounting frame 53 to move the material moving clamping finger assemblies 56 back and forth. The material moving lifting cylinder 54 drives the material moving clamping finger assemblies 56 to rise and fall. The material moving clamping finger assemblies 56 are used to clamp the drip chamber, move the drip chamber, and place it in the translation glue adding assembly 7 for glue adding.

[0050] Further, such as Figure 7 As shown, the capping finger assembly 68 includes a capping finger 681, a finger cylinder 682 for driving the capping finger 681 to open and close, and a top-loading cylinder 683. The capping finger 681 is provided with a drip chamber accommodating cavity 6811 and a top-loading channel 6812. The upper end of the drip chamber accommodating cavity 6811 is open, and the top-loading channel 6812 is located above the drip chamber accommodating cavity 6811 and passes through the capping finger 681 from front to back; a cylinder fixing block 684 is fixed on the side of the finger cylinder 682, and the top-loading cylinder 683 is fixedly connected to the cylinder fixing block 684. The rod head of the top-loading cylinder 683 faces downward and is fixedly connected to the top-loading block 6831 at the rod head. The top-loading block 6831 is horizontally arranged and extends into the top-loading channel 6812. The top-loading cylinder 683 drives the top-loading block 6831 to rise and fall in the top-loading channel 6812. When installing the cap, the capping fingers 681 clamp the drip chamber, and one end of the blood outlet of the drip chamber protrudes from the open drip chamber accommodating cavity 6811. The top-loading cylinder 683 drives the top-loading block 684 to descend in the top-loading channel, conflicts with one end of the blood outlet of the drip chamber and presses the drip chamber downward, completing the assembly of one end of the blood inlet of the drip chamber and the lid. The structure is simple and compact, the capping effect is good and the efficiency is high, and there is no need to clamp the drip chamber too tightly to avoid damage to the drip chamber. When unloading, the capping fingers 681 are opened and the top-loading block 684 descends to lightly push the drip chamber, helping the drip chamber to fall more accurately into the conveying fixture below when it is separated from the capping fingers 681.

[0051] As a preferred solution, Figure 8As shown, the translational glue adding assembly 7 includes a glue adding mounting frame 71, a glue adding translational driving source 72 horizontally fixedly connected to the glue adding mounting frame 71, a glue adding mechanism 73 slidingly connected to the glue adding mounting frame 71, and a glue storage box 74 located on one side of the glue adding translation plate 71. The glue adding translational driving source 72 can drive the glue adding mechanism 73 to translate left and right; the glue adding mechanism 73 includes a glue adding translation plate 731, a glue adding lifting cylinder 732 is fixedly connected to the outer side of the glue adding translation plate 731, the rod head of the glue adding lifting cylinder 732 is fixedly connected to the glue adding lifting plate 733 and can drive the glue adding lifting plate 733 to rise and fall, and a plurality of glue adding finger assemblies 734 are fixedly connected to the glue adding lifting plate 733. The glue adding translation drive source 72 drives the glue adding mounting frame 71 to drive the glue adding clamping finger assembly 734 to translate left and right under the material moving assembly 5 and the cover assembly 6. The glue adding clamping finger assembly 734 is used to clamp and fix the drip chamber. The glue adding lifting cylinder 732 drives the glue adding clamping finger assembly 734 to rise and fall, and places one end of the blood inlet of the drip chamber into the glue storage box 74 for glue adding.

[0052] Further, such as Figure 9 As shown, the glue adding finger assembly 734 includes a glue adding finger 735 and a glue adding finger cylinder 736 that drives the glue adding finger 735 to open and close. The glue adding finger 735 is "L"-shaped, including a connecting portion 7351 and a clamping portion 7352. The clamping portion 7352 extends horizontally above the glue storage box 74.
