Description

Technical Field

[0001] This utility model relates to the field of medical consumable production equipment, and in particular to a directional feeding device for dialyzer end caps. Background Technology

[0002] In dialyzer manufacturing, the consistent orientation of the dialysate inlet around the end cap is crucial and is a key indicator of product quality. However, in actual production, the end cap feeding direction is not always consistent. This leads to significant manpower and time spent adjusting the end cap orientation during subsequent assembly. Currently, most dialyzers on the market have the dialysate inlet designed as an integral part of the shell, resulting in a lack of existing technology for adjusting the end cap orientation during feeding. Therefore, there is an urgent need for an efficient end cap orientation adjustment device to replace manual operation. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a directional feeding device for dialyzer end caps, solving the issue of inconsistent dialysate flow direction during end cap feeding.

[0004] A directional feeding device for a dialyzer end cap, the end cap having a blood inlet and a dialysate inlet, wherein the dialysate inlet is a circumferentially protruding structure, characterized in that it comprises:

[0005] A direct vibration feeding assembly, wherein the material channel of the direct vibration feeding assembly continuously feeds the end cap;

[0006] A stationary material channel assembly is disposed in the conveying direction of the linear vibrating feeding assembly. The stationary material channel plate of the stationary material channel assembly is connected to the material channel. The stationary material channel plate is provided with a material arrival sensor for detecting the end cap conveyed to a receiving part of the stationary material channel plate.

[0007] An end cap transfer mechanism drives two finger clamps to move toward the stationary material channel plate. The finger clamps are inserted into the inner cavity of the end cap. The two finger clamps are driven by a pneumatic gripper to press the inner wall of the end cap in the opposite direction to achieve clamping. The end cap transfer mechanism moves the clamped end cap.

[0008] The end cap orientation mechanism has a feeding plate with a positioning hole that matches the blood inlet. The rotary cylinder of the end cap orientation mechanism drives the lever to rotate circumferentially along the positioning hole. The blocking drive cylinder of the end cap orientation mechanism drives the blocking block to move along the conveying direction perpendicular to the material channel. The blocking block cooperates with the lever to limit the rotation angle of the dialysate inlet, so that the dialysate inlet is forcibly corrected to a preset direction.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the initial orientation of the end cap is completed by the direct vibration feeding component and the stationary material channel component, and then the dialysate flow direction of the end cap is corrected to a uniform direction by the cooperation of the blocking block and the lever in the end cap orientation mechanism, thus solving the problem of inconsistent dialysate flow direction of the end cap during end cap feeding.

[0010] In the aforementioned directional feeding device for dialyzer end caps, the stationary feed channel plate further includes a second receiving portion. The first receiving portion is used to cooperate with the cylindrical portion of the end cap to position the end cap, and the second receiving portion is used to receive the dialysate outlet.

[0011] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by positioning a pair of columns in the receiving part, the circumferentially protruding dialysate outlet can be located in the receiving part, which can ensure the accurate positioning of each end cap on the stationary material channel plate and is more conducive to the end cap transfer mechanism to transfer the end cap.

[0012] In the aforementioned directional feeding device for dialyzer end caps, the first and second receiving portions are integrally designed and detachably mounted on the stationary feed channel plate.

[0013] In the aforementioned directional feeding device for dialyzer end caps, the end cap transfer mechanism further includes a second mounting plate, a second movable plate, two sets of lifting and picking components, and a third translation cylinder. The second mounting plate is fixedly mounted on the frame, the second movable plate is slidably mounted on the second mounting plate, the third translation cylinder is fixedly mounted on the second mounting plate, and the driving end of the third translation cylinder is connected to the second movable plate and can drive the second movable plate to translate. The two sets of lifting and picking components are mounted on the second movable plate.

[0014] One set of lifting and picking components clamps and moves the end cap after it has been corrected by the end cap orientation mechanism, while another set of lifting and picking components clamps and moves the end cap on the stationary material channel plate.

[0015] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by using two sets of lifting and picking components to simultaneously pick up the upper cover of the stationary material channel plate and the upper cover of the feeding plate, the working efficiency is accelerated and the feeding cycle of the device is improved.

[0016] In the aforementioned directional feeding device for dialyzer end caps, the lifting and feeding assembly includes a lifting drive unit and a clamping execution unit. The lifting drive unit includes a lifting cylinder, a guide rod, and a mounting plate. The clamping execution unit includes a pneumatic gripper and finger grippers. The lifting cylinder is disposed on the moving plate and its driving end is connected to the mounting plate. The guide rod slides through the moving plate and its downward end is connected to the mounting plate. The pneumatic gripper is fixedly disposed on the mounting plate and its driving end is connected to two finger grippers. The lifting cylinder drives the two finger grippers to move up and down along the guide direction of the guide rod.

[0017] In the aforementioned directional feeding device for dialyzer end caps, the end cap directional mechanism further includes a moving plate, a slide rail assembly, a translation cylinder, and a mounting plate. The mounting plate is fixedly mounted on the frame, and the moving plate is slidably mounted on the mounting plate via the slide rail assembly. The translation cylinder is fixedly connected to the mounting plate and its driving end is connected to the moving plate. The feeding plate, the rotating cylinder, and the blocking driving cylinder are all mounted on the moving plate.

[0018] In the aforementioned directional feeding device for dialyzer end caps, the end cap directional mechanism has at least two moving plates, the number of receiving portions on the stationary feed channel plate matches the number of moving plates, the two moving plates are driven to move by corresponding translation cylinders, and the two moving plates can move away from or close to each other. The lifting drive unit picking assembly has clamping execution units matching the number of moving plates, and the spacing between the clamping execution units in the two sets of lifting picking assemblies is different. The spacing between the two clamping execution units in one set of lifting picking assemblies matches the spacing between the two receiving portions on the stationary feed channel plate, and the spacing between the two clamping execution units in the other set of lifting picking assemblies matches the maximum spacing after the feeding plates on the two moving plates move away from each other.

[0019] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: the feeding plate, the rotary cylinder and the blocking drive cylinder are all set on the moving plate one. By adjusting the distance between multiple moving plates one, the angle correction of the action end cover and the spacing adjustment of multiple end covers can be realized simultaneously. Combining the two actions into one step simplifies the device structure and reduces costs.

[0020] By applying the technical solution of this utility model, a rotary cylinder drives a lever to adjust the position of the dialyzer end cap. The lever and the blocking block form a dynamic mechanical limit, and through the synergistic effect of rotational interference and translational constraint, the consistent angle of the dialysate inlet is ensured. This device keeps the dialysate inlet direction of the end cap consistent during cap feeding, which can greatly improve production efficiency and reduce the time and cost of manual adjustment.

[0037] The end cap 500 has a blood outlet 501 and a dialysate outlet 502, wherein the dialysate outlet 502 is a circumferentially protruding structure.

[0038] like Figures 1 to 5 As shown, this embodiment provides a directional feeding device for dialyzer end caps, including a direct vibration feeding assembly 100, a stationary feed channel assembly 200, a cap orientation mechanism 300, and an end cap transfer mechanism 400. The direct vibration feeding assembly 100 continuously feeds end caps 500 through the feed channel 102. The end caps 500 enter the stationary feed channel plate 201 of the stationary feed channel assembly 200 along the feeding direction and stop. The stationary feed channel plate 201 is provided with a receiving portion 202. After the end cap 500 falls into the receiving portion 202, a position signal is detected by the material arrival sensor 204. The end cap transfer mechanism 400 responds to the signal and drives the finger grippers 408 on the pneumatic grippers 407 to move towards the stationary feed channel plate 201. After the two finger grippers 408 are inserted into the inner cavity of the end cap 500, they expand in the opposite direction, achieving reverse clamping by squeezing the inner wall. The end cap transfer mechanism 400 transfers the clamped end cap 500 to the discharge plate 304 of the end cap orientation mechanism 300. The discharge plate 304 has a positioning hole that mates with the blood outlet 501 of the end cap. Because the dialysate outlet 502 of the end cap 500 transported by the feed channel 102 is randomly oriented, the rotary cylinder 302 drives the lever 303 to rotate circumferentially along the positioning hole. When the lever 303 contacts the dialysate outlet 502, it rotates the outlet, while simultaneously the blocking drive cylinder 306 drives the blocking block 307 to move perpendicular to the feed channel direction, forming a limiting space in conjunction with the lever 303. When the dialysate outlet 502 rotates to the constrained position of the blocking block 307 and the lever 303, the end cap 500 is forcibly corrected to a uniform orientation, achieving the effect of end cap orientation adjustment. After orientation correction, the two sets of finger grippers 408 of the end cap transfer mechanism 400 operate synchronously. The first group picks up the newly arrived end cap 500 from the stationary material channel plate 201; the second group picks up the already corrected end cap 500 from the discharge plate 304. The translation cylinder 3 403 drives the moving plate 2 402 to move horizontally, transferring the two groups of end caps 500 to their respective next processes, completing the directional feeding cycle.

[0039] The structure of each part will be described in detail below with reference to the attached diagram.

[0040] As attached Figure 1As shown, the overall device consists of a direct vibration feeding assembly 100, a stationary material channel assembly 200, an end cap orientation mechanism 300, and an end cap transfer mechanism 400. The stationary material channel assembly 200 is positioned in the conveying direction of the direct vibration feeding assembly 100, the end cap orientation mechanism 300 is positioned on one side of the stationary material channel assembly 200, and the end cap transfer mechanism 400 is positioned above the stationary material channel assembly 200 and the end cap orientation mechanism 300.

[0041] See Figure 2As shown, the vertical vibration feeding assembly 100 and the stationary material channel assembly 200 work together to complete the initial orientation and conveying control of the end cap 500. The vertical vibration feeding assembly 100 includes a vertical vibrator 101, a material channel 102, and a baffle plate 103. The vertical vibrator 101 is fixed to the frame and provides a vibration power source for the material channel 102, driving the end cap 500 to be continuously conveyed along the material trough of the material channel 102 towards the stationary material channel assembly 200. The width of the material trough is slightly larger than the diameter of the end cap 500, ensuring that the end cap 500 can slide freely along the material channel 102; the baffle plate 103 is set at the top of the material channel 102, and its lower end protrudes slightly from the inner wall of the material trough, restricting the vertical displacement space of the end cap 500 and preventing the end cap 500 from jumping off due to vibration during the conveying process. The stationary feed channel assembly 200's stationary feed channel plate 201 docks with the end of the feed channel 102. The end cap 500 is moved from the feed channel 102 to the receiving portion 202 of the stationary feed channel plate 201 and stops. The main body of the end cap 500, except for the blood outlet 501 and the dialysate outlet 502, is cylindrical. The receiving portion 202 forms a barrier against the main body of the end cap 500 through two angled sidewalls, thereby restricting the end cap 500 to a preset position, ensuring that the position grasped by the finger clamp (408) is consistent each time. The receiving portion 202 is designed as a split unit, detachably mounted on the stationary feed channel plate 201, and its position is adjusted using a positioning pin 205 to adapt to the positioning requirements of end caps 500 of different specifications. When the end cap 500 reaches the receiving portion 202, the material arrival sensor 204 detects the positioning signal and triggers the end cap transfer mechanism 400 to operate. To address the random orientation of the dialysate outlet 502 of the end cap 500, the stationary channel 201 also includes a second receiving section 203. This second receiving section 203 is integrated with the first receiving section 202 and is detachably mounted on the stationary channel plate 201. If the dialysate outlet 502 faces the conveying direction of the channel 102, when the end cap 500 is moved to the stationary channel plate 201, the dialysate outlet 502 will extend into the second receiving section 203, avoiding interference through spatial avoidance. If the dialysate outlet 502 faces the opposite conveying direction, the sidewall of the first receiving section 202 restricts its offset, ensuring the consistency of the end cap 500's posture on the stationary channel plate 201. Through the docking design between the channel 102 and the stationary channel plate 201, the complementary spatial constraints between the first receiving section 202 and the second receiving section 203, and the adjustable structure of the positioning pin 205, the initial orientation and stable docking of the end cap 500 are achieved, providing a foundation for subsequent precise positioning. Understandably, when there are multiple material troughs with conveying end caps 500 in the material channel 102, the corresponding number of receiving parts 1 202 and receiving parts 203 also need to be set on the corresponding stationary material channel plate 201.

[0042] It should be noted that the receiving section 202 can also be supported by a space for a receiving end cap 500 by several protrusions provided on the stationary material channel plate 201.

[0043] See Figure 3As shown, the end cap orientation mechanism 300 achieves forced angle correction of the dialysate outlet 502 of the end cap 500 through mechanical linkage. The end cap orientation mechanism 300 includes a mounting plate 301, a slide rail assembly 311, a moving plate 310, a rotary cylinder 302, a lever 303, a discharge plate 304, an avoidance notch 305, a blocking drive cylinder 306, a blocking block 307, and a translation cylinder 312. The mounting plate 301 is fixedly mounted on the frame, and the moving plate 310 is slidably mounted on the mounting plate 301 along the conveying direction perpendicular to the feed channel 102 via the slide rail assembly 311. The translation cylinder 312 is fixedly connected to the mounting plate 301, and its drive end is connected to the moving plate 310. The moving plate 310 is driven by the translation cylinder 312. The feeding plate 304, rotary cylinder 302, and blocking drive cylinder 306 are mounted on the moving plate 310 to achieve overall position adjustment of the feeding plate 304, rotary cylinder 302, and blocking drive cylinder 306. The sliding setting of the moving plate 310 is to adjust the distance between the end caps on the two feeding plates 304 in the end cap orientation mechanism 300. Since the distance between the two material troughs in the direct vibration feeding assembly 100 is different from the distance required for feeding the end cap 500, it is necessary to drive the moving plate 310 to move by the translation cylinder 312 to adjust the distance. Accordingly, at least two moving plates 310 are slidably mounted on the mounting plate 301. The corresponding number of rotary cylinders 302, levers 303, feeding plates 304, blocking drive cylinders 306, blocking blocks 307, and translation cylinders 312 on the moving plate 310 are required. The stationary material channel plate 201 also needs an equal number of receiving parts 202 and 203. The movement of the moving plate 310 can be driven by a single translation cylinder 312, or by a number of translation cylinders 312 corresponding to the moving plate 310. It is understandable that when no spacing adjustment is required, the slide rail assembly 311 and the moving plate 310 can be omitted, and the feeding plate 304, rotary cylinder 302, and blocking drive cylinder 306 are directly mounted on the mounting plate 301. Below the feeding plate 304 of the rotary cylinder 302 of the end cap orientation mechanism 300, the lever 303 connected to the drive end of the rotary cylinder 302 extends above the feeding plate 304. The lever 303 is driven by the rotary cylinder 302 to correct the circumferential angle of the end cap 500. The discharge plate 304 has a through positioning hole that matches the blood outlet 501 of the end cap 500. A clearance notch 305 is provided on the side of the discharge plate 304 to provide space for the rotation of the lever 303. The arc-shaped trajectory of the clearance notch 305 matches the rotation path of the lever 303 to prevent motion interference. The drive end of the rotary cylinder 302 is connected to the drive lever 303, causing the lever 303 to rotate around the axis of the positioning hole. When the end cap 500 is placed on the discharge plate 304, the lever 303 contacts the dialysate outlet 502 during the driving process and drives the dialysate outlet 502 to rotate, causing the end cap 500 to rotate around the positioning hole as a circumferential fixed position.A blocking drive cylinder 306 is installed on the moving plate 310, located on one side of the discharge plate 304. The driving end of the blocking drive cylinder 306 is connected to the blocking block 307, driving the blocking block 307 to move along the conveying direction of the vertical material channel 102, forming a dynamic clamping space with the lever 303. The initial positions of the lever 303 and the blocking block 307 are located on both sides of the positioning hole, and the lever 303 rotates around the positioning hole at an angle greater than 180°. When the rotary cylinder 302 is activated, the lever 303 pushes the dialysate outlet 502 to rotate, and the blocking block 307 simultaneously approaches and limits the maximum rotation angle of the dialysate outlet 502. It is understood that the limiting surface of the blocking block 307 can also be provided with a replaceable gasket to provide flexible contact for different dialysate outlet 502 thicknesses, avoiding rigid impact damage.

[0044] Furthermore, to prevent the end cap 500 from colliding with the blocking block 307 during the process of placing it onto the feeding plate 304, the end cap orientation mechanism also includes a translation cylinder 308. The driving end of the translation cylinder 308 is connected to the blocking drive cylinder 306, thereby driving the blocking block 307 away from or towards the feeding plate 304.

[0045] See Figure 4 In another embodiment of the end cap orientation mechanism, the two blocking blocks 307 can also be controlled by a blocking drive cylinder 306 to cooperate with the two levers 303, which requires the two levers 303 to rotate in opposite directions. In this case, the blocking drive cylinder 306 is connected to the mounting plate 301 via a fixing plate 309.

[0046] See Figure 1 and Figure 5As shown, the end cap transfer mechanism 400 is mounted above the direct vibration feeding assembly 100, the stationary material channel assembly 200, and the end cap orientation mechanism 300. It achieves synchronous clamping and efficient transfer of the end cap 500 through a dual-station lifting and picking assembly. Mounting plate 2 401 is fixedly connected to the frame, with a height higher than other components to ensure uninterrupted transfer path. Moving plate 2 402 is horizontally slidable on mounting plate 2 401 along the conveying direction of the material channel 102 via a slide rail. Translation cylinder 3 403 is fixedly mounted on mounting plate 2 401, with its drive end connected to moving plate 2 402. Moving plate 2 402 is driven by translation cylinder 3 403, and its stroke covers the entire path from the stationary material channel plate 201 to the discharge plate 304. Two sets of lifting and picking components are arranged side by side on the moving plate 2 402, corresponding to the uncorrected end cap 500 of the stationary material channel plate 201 and the corrected end cap 500 of the discharging plate 304, respectively, to achieve synchronous picking and discharging. Each set of lifting and picking components includes a lifting drive unit and a clamping execution unit. Each set of lifting and picking components may have more than two clamping execution units, and the number of clamping execution units is the same as the number of receiving parts 202 on the stationary material channel plate 201. The spacing between the multiple clamping execution units in the two sets of lifting and picking components may be different. The spacing between the clamping execution units in one set of lifting and picking components must match the spacing between the two receiving parts 202 on the stationary material channel plate 201, and the spacing between the clamping execution units in the other set of lifting and picking components must match the maximum spacing between the discharging plates 304 on the two moving plates 310 after they are far apart. The lifting drive unit includes a lifting cylinder 404, a guide rod 405, and a mounting plate 406. Lifting cylinder 404 is vertically fixed to moving plate 402, and the piston rod end is connected to mounting plate 406. Guide rod 405 passes through the linear bearing of moving plate 402, and the downward-facing end of guide rod 405 is fixedly connected to mounting plate 406 in parallel with lifting cylinder 404 to ensure the stability of the lifting movement of mounting plate 406. The clamping execution unit includes pneumatic grippers 407 and finger grippers 408. Pneumatic grippers 407 are installed at the bottom of mounting plate 406 and drive the two finger grippers 408 to perform clamping actions. The two finger grippers 408 are inserted into the end cover 500 and open in the opposite direction under the drive of pneumatic grippers 407, achieving non-destructive clamping through frictional contact. Translation cylinder 403 drives moving plate 402 to move directly above the stationary material channel plate 201, and lifting cylinder 404 presses down to insert the finger grippers 408 into the inner cavity of end cover 500. Pneumatic gripper 407 drives finger gripper 408 to expand and clamp, while lifting cylinder 1 404 retracts, lifting end cap 500 away from stationary material channel plate 201. Translation cylinder 3 403 pushes moving plate 2 402 to slide above the discharge plate 304, during which time the second set of lifting and picking components simultaneously descends to pick up the calibrated end cap 500. The first set of finger grippers 408 releases the uncalibrated end cap 500 into the positioning hole of the discharge plate 304; the second set of finger grippers 408 moves the calibrated end cap 500 to the next assembly station. Moving plate 2 402 returns to its initial position, entering the next work cycle.By using two sets of lifting and picking components that operate independently, and achieving synchronous "picking-and-placing" through cylinder timing control, the efficiency is higher than that of a single lifting and picking component for picking and placing before and after end cap alignment. The finger gripper 408 is understandably covered with a polyurethane liner to provide sufficient friction while preventing scratches on the dialysate outlet 502.
