Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] An embodiment of the present invention provides an automated production system for ultrafiltration membrane pressure testing, assembly and packaging, including a pressure testing device 1, an assembly slide 2, a packing slide 3, a hoisting device 4, and a handling device for transporting filter cartridges between various workstations.

[0036] As shown Figure 1 in the figure, the pressing device 1 and the handling device are both arranged within the operation area. Part of the assembly slide table 2 is distributed within the operation area, and the other part is distributed within the safety area. Part of the packing slide table 3 is distributed within the operation area, and the other part is distributed within the safety area. The hoisting device 4 is arranged within the safety area, and the hoisting device 4 is distributed above the packing slide table 3. A protective fence 5 is arranged between the operation area and the safety area. Since the ultrafiltration membrane is large in weight and volume, the operation area and the safety area are divided by the protective fence 5, and the staff only need to operate within the safety area.

[0037] As shown Figure 1 in the figure, the handling device includes a running track 6 and a robotic arm, and the robotic arm is slidably arranged on the running track 6. The pressing device 1 is distributed on one side of the running track 6, the assembly slide table 2 is distributed on the other side of the running track 6, and the packing slide table 3 and the hoisting device 4 are distributed outside one end of the running track 6. In addition, as a further preference of the present invention, a number of turnover tables 7 are also arranged within the operation area, and the turnover tables 7 are used for the turnover storage after the filter cartridge pressing and / or assembly operations.

[0038] The application process of this device:

[0039] First, the staff transports all or in batches the ultrafiltration membrane filter cartridges to be operated to the turnover table 7 near the pressing device 1 in the operation area. After the transportation is completed, the staff withdraws to the safety area. The handling device and the pressing device 1 are started, and the robotic arm moves the filter cartridge from the turnover table 7 to the pressing device 1 arranged in the operation area for pressing treatment. After the pressing is completed, it is transported by the robotic arm to the turnover table 7 near the assembly slide table 2 in the operation area. Then, the robotic arm transports the pressed filter cartridge from the turnover table 7 to the assembly slide table 2, and the assembly slide table 2 is started to make the filter cartridge move linearly on the assembly slide table 2, sliding from the operation area to the safety area, and the staff manually assembles the filter cartridge on the assembly slide table 2 in the safety area. After the assembly process is completed, the assembly slide table 2 is started again to make the filter cartridge move linearly on the assembly slide table 2, sliding back from the safety area to the operation area. Subsequently, it is transported by the robotic arm to the packing slide table 3, and the packing slide table 3 is started to make the filter cartridge move linearly on the packing slide table 3, sliding from the operation area to the safety area. Finally, the filter cartridge is lifted by the hoisting device 4, and with the assistance of manual operation, the filter cartridge is moved into the packing box.

[0040] Embodiment 2

[0041] The main structure of this embodiment is the same as that of Embodiment 1, the difference being that: the structure of the assembly slide table 2 is defined in this embodiment.

[0042] Specifically, the assembly slide table 2 includes an assembly fixing frame 2-1, a first Y-axis slide carriage 2-2, and two first X-axis slide carriages 2-3.

[0043] As Figure 1 shown, a first guide rail 2-4 is provided on the top of the assembly fixing frame 2-1. A slider is provided at the bottom of the first Y-axis slide carriage 2-2. The first Y-axis slide carriage 2-2 is slidably mounted on the assembly fixing frame 2-1 through the slider and the first guide rail 2-4. The first Y-axis slide carriage 2-2 can linearly move along the assembly fixing frame 2-1 and operate between the working area and the safety area. The driving structure of the first Y-axis slide carriage 2-2 is a rodless cylinder 2-9. The rodless cylinder 2-9 is provided on the assembly fixing frame 2-1 and is parallel to the first guide rail 2-4. The moving part of the rodless cylinder 2-9 is fixedly connected to the first Y-axis slide carriage 2-2 and can drive the first Y-axis slide carriage 2-2 to linearly move along the assembly fixing frame 2-1. A second sensor 2-11 is provided on the rodless cylinder 2-9, and the second sensor 2-11 is used to detect the moving distance of the first Y-axis slide carriage 2-2.

[0044] As Figure 1 shown, two second guide rails 2-5 perpendicular to the first guide rail 2-4 are provided on the top of the first Y-axis slide carriage 2-2. Sliders are provided at the bottoms of the two first X-axis slide carriages 2-3 and are respectively slidably mounted on the two second guide rails 2-5. First V-shaped positioning members 2-6 for supporting the filter cartridge are respectively fixedly mounted on the tops of the two first X-axis slide carriages 2-3. The two first X-axis slide carriages 2-3 can be driven to slide in opposite directions through the first X-axis slide carriage driving device, so as to adjust the distance between the two first V-shaped positioning members 2-6, thereby adapting to filter cartridges of different sizes.

[0045] In this embodiment, the first X-axis carriage driving device includes a first motor 2-12, a first synchronous pulley 2-13, a second synchronous pulley 2-14, and a first ball screw 2-15 with opposite threads. The second synchronous pulley 2-14 is fixed on the first ball screw 2-15 with opposite threads. The first motor 2-12 is fixed at the bottom of the first Y-axis carriage 2-2. The output end of the first motor 2-12 is drivingly connected to the first synchronous pulley 2-13. The first synchronous pulley 2-13 and the second synchronous pulley 2-14 are connected by a synchronous belt. The first ball screw 2-15 with opposite threads is rotationally connected to the first Y-axis carriage 2-2 (through bearings and bearing seats), and the first ball screw 2-15 with opposite threads is parallel to the second guide rail 2-5. The first ball screw 2-15 with opposite threads is provided with two threaded sections with opposite directions. Two first screw sleeves 2-16 are respectively threadedly installed on the two threaded sections. The two first screw sleeves 2-16 are respectively fixedly connected to the two first X-axis carriages 2-3. The first motor 2-12 can drive the first synchronous pulley 2-13 to rotate, and then drive the second synchronous pulley 2-14 to rotate. The second synchronous pulley 2-14 drives the first ball screw 2-15 with opposite threads to rotate self, which can drive the two first screw sleeves 2-16 to move, and then drive the two first X-axis carriages 2-3 to move towards each other or away from each other, so as to realize the adjustment of the distance between the two first V-shaped positioning members 2-6.

[0046] As Figure 1 shown, as a further preference of this embodiment, a second V-shaped positioning member 2-7 and a cylinder 2-8 are arranged between the two first X-axis carriages 2-3. The cylinder 2-8 is fixedly arranged at the center position of the first Y-axis carriage 2-2. The second V-shaped positioning member 2-7 is fixedly connected to the top output end of the cylinder 2-8. The cylinder 2-8 can drive the second V-shaped positioning member 2-7 to move up and down, and a first sensor 2-10 is arranged on the cylinder 2-8. The first sensor 2-10 is used to detect the moving height of the second V-shaped positioning member 2-7.

[0047] In this embodiment, the two first V-shaped positioning members 2-6 are symmetrically distributed on both sides of the second V-shaped positioning member 2-7. Rubber pads are not provided in the positioning grooves of the first V-shaped positioning member 2-6 and the second V-shaped positioning member 2-7. Rubber pads are arranged at the outer ends of the two first X-axis carriages 2-3. The arrangement of the rubber pads can buffer and protect the filter cartridge. In this embodiment, the filter cartridge is supported by three V-shaped positioning members together, which can improve the structural stability. In addition, the height of the second V-shaped positioning member 2-7 is variable, which can lift the filter cartridge to facilitate the robotic arm to take out the filter cartridge from the assembly slide 2.

[0048] The application process of the assembly slide 2 in this embodiment:

[0049] First, start the first motor 2-12. The first motor 2-12 drives the two first X-axis carriages 2-3 to move towards or away from each other, so that the distance between the two first V-shaped positioning members 2-6 is adapted to the length of the filter cartridge.

[0050] After the adjustment is completed, the robotic arm places the filter cartridge on one side of the assembly slide 2 in the working area, and the three V-shaped positioning members jointly support the filter cartridge.

[0051] Turn on the rodless cylinder 2-9. The rodless cylinder 2-9 drives the first Y-axis carriage 2-2 to move linearly along the assembly fixing frame 2-1 until it reaches the safe area, and then the rodless cylinder 2-9 stops working.

[0052] The staff manually performs the assembly operation on the filter cartridge.

[0053] After the assembly is completed, turn on the rodless cylinder 2-9 again. The rodless cylinder 2-9 drives the first Y-axis carriage 2-2 to move linearly along the assembly fixing frame 2-1, so that the first Y-axis carriage 2-2 returns to the working area.

[0054] Start the cylinder 2-8. The cylinder 2-8 drives the second V-shaped positioning member 2-7 to move upward, thereby lifting the filter cartridge. The robotic arm removes the filter cartridge from the assembly slide 2, and then starts the cylinder 2-8 again to return the second V-shaped positioning member 2-7 to its original position.

[0055] Embodiment 3

[0056] The main structure of this embodiment is the same as that of Embodiment 2, the difference being that the structure of the hoisting device 4 is defined in this embodiment.

[0057] Specifically, the hoisting device 4 includes a hoisting fixing frame 4-1 and a hoisting assembly; the hoisting assembly includes a second Y-axis carriage 4-2, a second motor 4-3, a transmission spline shaft 4-4, and two wire pulley wheels 4-5.

[0058] As Figure 1 shown, a third guide rail 4-11 is provided at the top of the hoisting fixing frame 4-1. The second Y-axis carriage 4-2 is movably installed on the third guide rail 4-11 through a slider. The second Y-axis carriage 4-2 can move linearly along the third guide rail 4-11, and the driving structure of the second Y-axis carriage 4-2 can be a rodless cylinder.

[0059] As Figure 1As shown, the second motor 4-3 is fixedly installed at the bottom of the second Y-axis carriage 4-2. The transmission spline shaft 4-4 (with axially distributed splines on its outer surface) is rotatably installed at the bottom of the second Y-axis carriage 4-2 through bearings and bearing mounts, and the transmission spline shaft 4-4 is perpendicular to the third guide rail 4-11. The second motor 4-3 is drivingly connected to the transmission spline shaft 4-4, and the second motor 4-3 can drive the transmission spline shaft 4-4 to rotate. Two wire pulling wheels 4-5 are arranged on the transmission spline shaft 4-4 and can rotate with the rotation of the transmission spline shaft 4-4. A hoisting wire for hoisting the filter cartridge is arranged on the wire pulling wheel 4-5. When the second motor 4-3 drives the transmission spline shaft 4-4 to rotate, it can drive the two wire pulling wheels 4-5 to rotate, and then can adjust the hoisting length of the hoisting wire, thereby adjusting the hoisting height of the filter cartridge.

[0060] In this embodiment, the hoisting device 4 further includes two second X-axis carriages 4-6. Two fourth guide rails 4-7 perpendicular to the third guide rail 4-11 are arranged at the bottom of the second Y-axis carriage 4-2. The two second X-axis carriages 4-6 are respectively slidably installed on the two fourth guide rails 4-7 through sliders. Bearing seats 4-8 are respectively fixedly arranged on the two second X-axis carriages 4-6. A connecting piece is arranged inside the wire pulling wheel 4-5. The connecting piece is rotatably installed in the bearing seat 4-8 through a bearing, and the connecting piece is provided with a central through hole adapted to the shape and specifications of the transmission spline shaft 4-4. The wire pulling wheel 4-5 is provided with a central through hole. The wire pulling wheel 4-5 and the connecting piece are both sleeved on the transmission spline shaft 4-4, and the wire pulling wheel 4-5 and the connecting piece can move along the transmission spline shaft 4-4. When the second X-axis carriage 4-6 slides along the fourth guide rail 4-7, it can drive the bearing seat 4-8, the connecting piece and the wire pulling wheel 4-5 to slide along the fourth guide rail 4-7 together. That is to say, the two wire pulling wheels 4-5 can not only rotate with the rotation of the transmission spline shaft 4-4, but also move along the transmission spline shaft 4-4, so as to adjust the distance between the two wire pulling wheels 4-5 to adapt to filter cartridges of different sizes.

[0061] In this embodiment, the structure for driving the second X-axis carriage 4-6 to slide is the second X-axis carriage driving device. The second X-axis carriage driving device includes a third motor, a third synchronous pulley, a fourth synchronous pulley, and a second left-right ball screw 4-9. The fourth synchronous pulley is fixed on the second left-right ball screw 4-9. The third motor is fixed on the second Y-axis carriage 4-2. The output end of the third motor is drivingly connected to the third synchronous pulley. The third synchronous pulley and the fourth synchronous pulley are connected by a synchronous belt for transmission. The second left-right ball screw 4-9 is rotationally connected to the second Y-axis carriage 4-2 through a bearing and a bearing support, and the second left-right ball screw 4-9 is parallel to the fourth guide rail 4-7. The second left-right ball screw 4-9 is provided with two threaded segments with opposite directions. Two second screw sleeves 4-10 are threadedly installed on the two threaded segments respectively. The two second screw sleeves 4-10 are respectively fixedly connected to the two second X-axis carriages 4-6. The third motor can drive the third synchronous pulley to rotate, and then drive the fourth synchronous pulley to rotate. The fourth synchronous pulley drives the second left-right ball screw 4-9 to rotate on its own axis, which can drive the two second screw sleeves 4-10 to move, and then drive the two second X-axis carriages 4-6 to move towards each other or away from each other, so as to adjust the distance between the two wire pulling wheels 4-5.

[0062] The application process of the hoisting device 4 in this embodiment:

[0063] First, the robotic arm places the assembled filter cartridge on one side of the packing slide table 3 (the packing slide table 3 has the same structure as the assembly slide table 2) in the working area, and slides it to the safe area under the drive of the rodless cylinder;

[0064] Turn on the third motor. The third motor drives the two second X-axis carriages 4-6 to move towards each other or away from each other, so that the distance between the two wire pulling wheels 4-5 is adapted to the length of the filter cartridge, and then turn off the third motor;

[0065] Turn on the second motor 4-3. The second motor 4-3 drives the transmission spline shaft 4-4 to rotate, drives the two wire pulling wheels 4-5 to rotate, and then adjusts the hoisting length of the hoisting wire, and then turn off the second motor 4-3;

[0066] The staff fixes the hoisting wire to both sides of the filter cartridge;

[0067] After the fixing is completed, turn on the second motor 4-3 again. The second motor 4-3 drives the transmission spline shaft 4-4 to rotate, and then drives the two wire pulling wheels 4-5 to rotate in the reverse direction to lift the filter cartridge;

[0068] Start the rodless cylinder. The rodless cylinder drives the second Y-axis carriage 4-2 to move linearly along the third guide rail 4-11 until it moves directly above the packing box;

[0069] Turn on the second motor 4-3, slowly drop the filter cartridge into the packing box, and complete the packing operation.

[0070] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and modifications made without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
