Description

Technical Field

[0001] The utility model relates to the technical field of dialyzer production, in particular to an aluminum foil welding system. Background Art

[0002] The dialyzer mainly utilizes the principle of semipermeable membrane to introduce the patient's blood and dialysate into the dialyzer at the same time. The two flow in opposite directions on both sides of the dialyzer membrane. With the help of the solute gradient, osmotic gradient and water pressure gradient on both sides of the membrane, the toxins and excess water retained in the body can be removed, while replenishing the body's necessary substances.

[0003] The dialyzer needs to undergo a sealing process during the production process to ensure the sealing of the internal environment of the dialyzer shell. Specifically, during operation, the hollow fiber bundle needs to be placed in the dialysis shell, and then the gaps between the hollow fiber bundles in the dialysis shell need to be filled with glue. In order to prevent the glue from entering the hollow fiber bundle from the end, aluminum foil needs to be fixed to the end of the hollow fiber bundle before glue injection to fix it, so as to fix and seal the hollow fiber bundle.

[0004] However, in the existing aluminum foil welding system, the stacking assembly for carrying the aluminum foil is fixed on the side of the workbench away from the packaging conveyor. The stacking assembly has a single placement cavity. When the aluminum foil in the placement cavity is used up, the machine needs to be stopped to manually refill the placement cavity, which affects the welding efficiency. Secondly, in the existing aluminum foil welding system, a plurality of suction holes for adsorbing the aluminum foil are provided on the flip plate. Each suction hole shares a negative pressure tube. The flip plate is flipped by a flip cylinder driving one side of the flip plate so that each aluminum foil on it is aligned with the end of each dialyzer shell one by one. Therefore, the position of each aluminum foil on the flip plate relative to the dialyzer shell cannot be adjusted individually, and the aluminum foil cannot be welded and positioned more accurately.

[0005] Therefore, how to provide an aluminum foil welding system that can solve at least one of the above technical problems is one of the technical problems that those skilled in the art need to solve. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0049] The first aspect of the present invention provides an aluminum foil welding system. Figures 1 to 3 As shown, it includes an aluminum foil feeding mechanism, a flip suction cup 4 and a welding device 5, wherein: the aluminum foil feeding mechanism includes a plurality of horizontally distributed aluminum foil placement cavities 21, and the plurality of aluminum foil placement cavities 21 have the freedom to rotate around the same vertical axis; the flip suction cup 4 is arranged on one side of the aluminum foil feeding mechanism, and the flip suction cup 4 has an adsorption groove 421 for driving a single aluminum foil to flip to align with the welding device 5; the welding device 5 includes a welding mechanism and a total driving assembly 52, and the welding mechanism and the flip suction cup 4 are connected to the power output end of the total driving assembly 52 to drive the welding mechanism and the flip suction cup 4 to move in the horizontal direction.

[0050] The aluminum foil welding system provided in the above embodiment has the following advantages:

[0051] 1. The aluminum foil feeding mechanism includes a plurality of horizontally distributed aluminum foil placement chambers 21. Multiple pieces of aluminum foil can be placed in each aluminum foil placement chamber 21. When the aluminum foil in one of the aluminum foil placement chambers 21 is used up, each aluminum foil placement chamber 21 rotates around the same vertical axis, and the aluminum foil in the next aluminum foil placement chamber 21 can be directly taken. The whole process does not require shutdown operation, thereby ensuring the continuity of aluminum foil welding and improving welding efficiency.

[0052] 2. The adsorption groove 421 on the flip suction cup 4 can drive a single aluminum foil to flip to align with the welding device 5, so that the position of each aluminum foil in the system relative to the dialyzer shell can be adjusted individually. Driven by the main drive assembly 52, the aluminum foil can be welded and positioned more accurately.

[0053] The structure of the aluminum foil feeding mechanism is described in detail below:

[0054] In some embodiments, Figure 4 and Figure 5 As shown, the aluminum foil feeding mechanism also includes a turntable drive assembly 1 and a turntable 2. The turntable 2 has a plurality of aluminum foil placement cavities 21. The power output end of the turntable drive assembly 1 is connected to the turntable 2 to drive the turntable 2 to rotate around a vertical axis, thereby realizing the rotation of the plurality of aluminum foil placement cavities 21 around the same vertical axis.

[0055] Among them, the turntable drive assembly may include structures such as a rotating motor and a rotating cylinder for rotating motion, and the power output shaft of the rotating cylinder is directly connected to the turntable 2. The turntable drive assembly may also include structures such as a linear cylinder and a linear hydraulic cylinder for linear motion, as well as transmission assemblies such as a connecting rod assembly and a crank slider assembly. The transmission assembly can convert linear motion into rotational motion.

[0056] In other words, any structure that can drive the turntable 2 to rotate can be the turntable driving assembly 1 mentioned in the above embodiment.

[0057] The number of the aluminum foil placement cavities 21 can be two, three, four or five.

[0058] In at least one embodiment, Figure 4 and Figure 5 As shown, there are two aluminum foil placement cavities 21, which are symmetrically arranged in the horizontal direction, and the distances between the two aluminum foil placement cavities 21 and the vertical axis are equal, so that the positions of the two aluminum foil placement cavities 21 can be consistent before and after the turntable 2 rotates, which is convenient for the aluminum foil transfer component 8 to take materials from the aluminum foil placement cavity 21.

[0059] like Figure 6 As shown, the aluminum foil feeding mechanism also includes a first sensor 012, which can detect whether there is aluminum foil in the aluminum foil placement cavity 21 grabbed by the aluminum foil transfer component 8. If the first sensor 012 detects that the aluminum foil in the aluminum foil placement cavity 21 has been used up, the control system controls the turntable drive component 1 to rotate, and rotates the aluminum foil placement cavity 21 with material to the position to be taken.

[0060] In some embodiments, Figure 4 and Figure 5As shown, the aluminum foil feeding mechanism further includes a lifting assembly 3, and a power output end of the lifting assembly 3 is connected to the fixed end of the turntable drive assembly 1 to drive the fixed end of the turntable drive assembly 1 to move in the vertical direction.

[0061] When in use, the stacked aluminum foil is manually placed in the aluminum foil placement chamber 21, the turntable driving assembly 1 rotates the aluminum foil 180 degrees, and after the aluminum foil transfer assembly 8 reaches the material picking position, the lifting assembly 3 lifts the stacked aluminum foil for the aluminum foil transfer assembly 8 to pick up the material.

[0062] The lifting assembly 3 can be a structure such as a linear cylinder, a linear hydraulic cylinder or a linear motor.

[0063] The structure of the flip suction cup 4 is described in detail below:

[0064] In some embodiments, Figure 2 As shown, the flip suction cup 4 includes a bracket 41, a suction cup 42 and a suction cup driving assembly 43. The suction cup 42 is rotatably matched with the bracket 41. The suction cup 42 has an adsorption groove 421. The fixed end of the suction cup driving assembly 43 is installed on the bracket 41. The power output end of the suction cup driving assembly 43 is connected to the suction cup 42 to drive the suction cup 42 to rotate around the horizontal axis.

[0065] When in use, the suction cup 42 is first parallel to the horizontal plane. The aluminum foil transfer component 8 places the aluminum foil in the adsorption groove 421. The adsorption groove 421 adsorbs the aluminum foil through negative pressure. Then the power output end of the suction cup drive component 43 drives the suction cup 42 to rotate 90° around the horizontal axis until the suction cup 42 is perpendicular to the horizontal plane. At this time, the aluminum foil is facing the end of the dialyzer shell 011, waiting for welding.

[0066] The suction cup 42 is in a circular shape, and an adsorption groove 421 is concavely provided in the inner circle of the suction cup 42 . A plurality of adsorption holes are provided on the bottom surface of the adsorption groove 421 . The vacuum equipment adsorbs the aluminum foil in the adsorption groove 421 through the adsorption holes.

[0067] Specifically, Figure 7 As shown, the flip suction cup 4 also includes a second sensor 013, which can detect whether there is aluminum foil in the adsorption groove 421. If the second sensor 013 detects that there is aluminum foil in the adsorption groove 421, the control system controls the power output end of the suction cup drive assembly 43 to drive the suction cup 42 to rotate, so as to align the aluminum foil with the end of the dialyzer shell 011.

[0068] The structure of the suction cup drive assembly 43 can be in various forms, and any structure that can drive the suction cup 42 to rotate around the horizontal axis relative to the bracket 41 can be the suction cup drive assembly 43 provided in the above embodiment. Its optional structure can refer to the turntable drive assembly 1, and will not be described in detail here to save space.

[0069] In at least one embodiment, the suction cup drive assembly 43 is implemented as a rotary cylinder.

[0070] The limiting structure used in conjunction with the welding device 5 in the aluminum foil welding system is described in detail below:

[0071] In some embodiments, to improve welding efficiency, the flip suction cup 4 is configured in plurality, and each flip suction cup 4 is provided with a welding device 5 opposite thereto. During operation, the plurality of welding devices 5 can simultaneously weld the plurality of aluminum foils to the ends of the plurality of dialyzer shells 011 .

[0072] like Figure 6 As shown, the aluminum foil welding system also includes a first limiting component 6 and a second limiting component 7. The side of each flip suction cup 4 facing away from the welding device 5 is arranged opposite to a first limiting component 6 or a second limiting component 7. The first limiting component 6 is used to limit the unwelded end face of the dialyzer shell 011 and the end face of the wire bundle, and the second limiting component 7 is used to limit the welded end face of the dialyzer shell 011.

[0073] The dialyzer housing 011 is welded in two steps. First, the aluminum foil is welded to one end of the dialyzer housing 011. At this time, the other end of the dialyzer housing 011 is against the first limiting assembly 6. The first limiting assembly 6 limits the unwelded end face and the end face of the tow of the dialyzer housing 011. After the welding of one end is completed, the dialyzer transport assembly 9 transports the dialyzer housing 011 to the next station. The second limiting assembly 7 limits the welded end face of the dialyzer housing 011 and accelerates the cooling of the welded end face. The welding device 5 welds the aluminum foil to the other end of the dialyzer housing 011.

[0074] Among them, since the first limiting component 6 needs to limit the unwelded end face and the wire bundle end face of the dialyzer housing 011 at the same time, the first limiting component 6 includes a support member 61, a stop block 62 and a cylinder 63; the power output end of the cylinder 63 is connected to the support member 61 to push the support member 61 to approach the end of the dialyzer housing 011; the support member 61 is used to limit the axial position and radial position of the glue injection cover at the end of the dialyzer housing 011, and the stop block 62 is connected to the support member 61; the stop block 62 is adjustable relative to the support member 61 along the axial direction of the dialyzer housing 011, and the stop block 62 is used to abut against the wire bundle end face to limit the position of the wire bundle end face.

[0075] The second limiting assembly 7 includes a cold abutment member, which is in the shape of a plate and is used to abut against one end of the dialyzer housing 011 that has been heat-welded, and also serves to accelerate cooling.

[0076] In some embodiments, Figure 8As shown, the flip suction cups 4 are configured into two groups along the loading direction of the dialyzer shell 011, and each group of flip suction cups 4 includes two rows of flip suction cups 4. The two rows of flip suction cups 4 are arranged parallel to the loading direction, one row is located on one side of the loading direction of the dialyzer shell, and the other row is located on the other side of the loading direction of the dialyzer shell. The two rows of flip suction cups 4 are staggered in a direction perpendicular to the loading direction.

[0077] The two groups of flip suction cups 4 are respectively set as a first group of flip suction cups 4 and a second group of flip suction cups 4 .

[0078] like Figure 8 As shown, the four flip suction cups 4 on the right are the first group of flip suction cups 4. In each row of flip suction cups 4 in the first group, the flip suction cups 4 and the first limiting components 6 are arranged alternately, that is, they are arranged in the order of one flip suction cup 4, one first limiting component 6, one flip suction cup 4, and one first limiting component 6.

[0079] like Figure 8 As shown, the four flip suction cups 4 on the left are the second group of flip suction cups 4. In each row of flip suction cups 4 of the second group, the flip suction cups 4 and the second limiting components 7 are arranged alternately, that is, they are arranged in the order of one flip suction cup 4, one second limiting component 7, one flip suction cup 4, and one second limiting component 7.

[0080] When in use, a plurality of dialyzer housings 011 are first processed at the station where the first group of flip suction cups 4 are located, and aluminum foil is welded to one end of each dialyzer housing 011. Among two adjacent dialyzer housings 011, aluminum foil is welded to the left end of one dialyzer housing 011, and aluminum foil is welded to the right end of the other dialyzer housing 011. After welding is completed, all the dialyzer housings 011 are transported to the station where the second group of flip suction cups 4 are located for processing, and aluminum foil is welded to the other end of each dialyzer housing 011. Among two adjacent dialyzer housings 011, aluminum foil is welded to the right end of one dialyzer housing 011, and aluminum foil is welded to the left end of the other dialyzer housing 011. The above method facilitates batch processing of dialyzer housings 011 and improves welding efficiency.

[0081] The structure of the welding device 5 is described in detail below:

[0082] In some embodiments, Figure 3 As shown, the welding mechanism includes a welding head 51 and a welding head driving assembly 53; the power output end of the welding head driving assembly 53 is connected to the welding head 51 to drive the welding head 51 to move in the horizontal direction, so that the welding head 51 can weld the aluminum foil to the end of the dialyzer shell 011; the bracket 41 in the flip suction cup 4 is connected to the fixed end of the welding head driving assembly 53, and the power output end of the main driving assembly 52 is connected to the fixed end of the welding head driving assembly 53.

[0083] When the aluminum foil is aligned with the end of the dialyzer shell 011, the main drive assembly 52 drives the fixed end of the welding head drive assembly 53 to move in the horizontal direction, and the welding head 51 and the bracket 41 can move in the horizontal direction synchronously, so as to approach the end of the dialyzer shell 011. After the aluminum foil fits the end of the dialyzer shell 011, the welding head drive assembly 53 is activated, and the welding head 51 welds the aluminum foil to the end of the dialyzer shell 011.

[0084] The welding head 51 can be connected to the power output end of the welding head driving assembly 53 through a hollow structure, so that the welding head 51 has a good heat dissipation effect.

[0085] Among them, the power output ends of the welding head driving assembly 53 and the main driving assembly 52 both perform linear motion, so the welding head driving assembly 53 and the main driving assembly 52 can be structures such as linear cylinders, linear hydraulic cylinders, linear motors, etc.

[0086] In at least one embodiment, the welding head driving assembly 53 and the overall driving assembly 52 may use linear cylinders.

[0087] The following is a detailed description of the transfer structure of the aluminum foil welding system:

[0088] In some embodiments, Figures 9 to 11 As shown, in order to facilitate the loading of aluminum foil, the aluminum foil welding system further includes an aluminum foil transfer assembly 8, and the aluminum foil transfer assembly 8 includes a material picking claw 81, and the material picking claw 81 is configured to move between the aluminum foil loading mechanism and the flip suction cup 4.

[0089] The picking claw 81 can be a suction cup, and the picking claw 81 can suck the aluminum foil by negative pressure to pick up the aluminum foil. The movement of the picking claw 81 between the aluminum foil feeding mechanism and the flip suction cup 4 can be achieved by a variety of structures, such as a linear cylinder, a transmission belt, a transmission chain, etc.

[0090] Of course, the picking claw 81 can also move up and down to pick up and put down the aluminum foil, and its up and down movement can be achieved by structures such as a linear cylinder and a linear motor.

[0091] In some embodiments, Fig. 9 As shown, in order to facilitate the transportation of the dialyzer, the aluminum foil welding system further includes a dialyzer transportation component 9 , and the dialyzer transportation component 9 includes a transportation claw 91 , and the transportation claw 91 is configured to move along the extension direction of the gap between the two rows of flip suction cups 4 .

[0092] The transport claw 91 can be any mechanical claw with a grasping capability. The movement of the transport claw 91 can also be achieved by structures such as a linear cylinder, a transmission belt, and a transmission chain.

[0093] The dialyzer shell positioning and clamping mechanism of the aluminum foil welding system is described in detail below:

[0094] In some embodiments, Fig. 9 As shown, the aluminum foil welding system also includes a conveying mechanism 018, which is arranged on the side of the flip suction cup 4 away from the welding device 5, and the conveying mechanism has multiple dialyzer housing bearing positions. When in use, the conveying mechanism 018 can transport the dialyzer housing to each group of flip suction cups 4, waiting for the positioning clamping mechanism to pick it up.

[0095] The conveying mechanism 018 may include a driving component and a supporting member connected to the driving component. The dialyzer housing may be placed on the supporting member, and the driving component may drive the supporting member to move along the loading direction.

[0096] The driving assembly may be a chain drive structure, a belt drive structure, or any structure that can drive the carrier to move along the feeding direction.

[0097] Specifically, one end of the support member can be fixedly connected to the power output end of the drive assembly, such as a chain or belt, and the other end can be bent into an arc or V shape, thereby limiting the rolling of the dialyzer shell and preventing the dialyzer shell thereon from rolling off.

[0098] In some embodiments, Figure 6 and Figure 7 As shown, the aluminum foil welding system also includes a positioning and clamping mechanism, which includes an upper positioning member 014 and a lower positioning member 015. The upper positioning member 014 is fixed on the mounting frame 016, and the lower positioning member 015 is installed on the lifting mechanism 017. When the lifting mechanism 017 is extended, the lower positioning member 015 can be lifted from below the conveying line to push the dialyzer shell 011 out of the conveying line and form a clamping cavity together with the upper positioning member 014 to position the dialyzer shell 011 and ensure that the dialyzer shell 011 is stable at a height position during hot welding.

[0099] Specifically, in order to more stably define the position of the dialyzer housing 011, the surfaces of the upper positioning member 014 and the lower positioning member 015 facing the dialyzer housing 011 can be bent into a V shape, so as to clamp the dialyzer housing 011 more firmly.

[0100] The cooling mechanism 10 of the aluminum foil welding system is described in detail below:

[0101] In some embodiments, Fig. 9 and Fig.12As shown, the aluminum foil welding system also includes a cooling mechanism 10, which includes a right clamping assembly 101 and at least one left clamping assembly 102. The right clamping assembly 101 includes a right clamping plate 1011 arranged opposite to the left clamping assembly 102, and the right clamping plate 1011 is configured to move in a direction gradually approaching or away from the left clamping assembly 102. A dialyzer shell clamping space is formed between the right clamping plate 1011 and each left clamping assembly 102.

[0102] When in use, the two ends of the dialyzer housing 011 are respectively facing the left clamping assembly 102 and the right clamping plate 1011, and the right clamping plate 1011 moves in a direction gradually approaching the left clamping assembly 102 until one end of the dialyzer housing 011 is pressed on the clamping end face of the left clamping assembly 102, and the other end is pressed on the right clamping plate 1011. The clamping end face of the left clamping assembly 102 and the right clamping plate 1011 absorb the heat from the end face of the dialyzer housing 011, thereby cooling the dialyzer housing 011.

[0103] The movement of the right clamping plate 1011 can be achieved by structures such as a linear cylinder, a linear hydraulic cylinder, and a linear motor.

[0104] To improve cooling efficiency, the left clamping assembly 102 can be configured as two, three, four or five, and a dialyzer housing 011 can be clamped between each left clamping assembly 102 and the right clamping plate 1011 .

[0105] In at least one embodiment, four left hold-down assemblies 102 are provided.

[0106] Specifically, the left clamping assembly 102 includes a left clamping plate, which can also be configured to move in a direction gradually approaching or away from the right clamping plate 1011. The movement of the left clamping plate can also be achieved by structures such as a linear cylinder, a linear hydraulic cylinder, and a linear motor.
