Technical Field

[0001] This invention relates to the field of injection molding technology, and specifically to a lower tube assembly device and assembly method. Background Technology

[0002] The lower tube assembly is an injection-molded part, consisting of a tube body and a tube connector. The tube body is connected to the sprue gate after injection molding. During the production of the lower tube assembly, the tube body and tube connector need to be pre-assembled to form the assembly. This includes removing the product from the injection molding machine cavity, trimming the sprue gate, and installing the lower tube connector. All of these operations are performed manually. Manual pre-assembly often results in incomplete sprue trimming and improper installation of the lower tube connector, easily leading to quality defects. Furthermore, it is inefficient, labor-intensive, and costly. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a lower tube assembly device and assembly method to improve the automation level of lower tube assembly operations, reduce quality abnormalities, and increase production efficiency.

[0004] The first technical solution adopted by the present invention to solve the technical problem is a pipe assembly device, including an assembly base and a water cutter assembly; The assembly base includes a workbench, on which a positioning fixture and an assembly push plate are provided. The positioning fixture is provided with a transverse groove for placing the tube body, and one end of the transverse groove is closed. The assembly push plate is located on the opening side of the transverse groove, and the assembly push plate is driven to move by the transverse moving assembly, which is mounted on the worktable. The water cutter assembly includes pneumatic shears and a collection box located below the pneumatic shears, with the pneumatic shears mounted on one side of the workbench via a bracket.

[0005] Furthermore, it also includes a tube loading robot, which is positioned between the assembly base and the injection molding machine.

[0006] Furthermore, it also includes a connector loading robot, which is disposed between the assembly base and the connector loading mechanism.

[0007] Furthermore, the connector feeding mechanism includes a frame and a temporary storage platform. A bakelite fixture is provided on the temporary storage platform. The bakelite fixture has a plurality of slots arranged on it for storing connectors. A fixing clamp is provided on the temporary storage platform for fixing the bakelite fixture.

[0008] Furthermore, the inner wall of the slot is provided with an anti-reverse mounting protrusion.

[0009] Furthermore, at least two temporary storage platforms are provided. The temporary storage platforms are horizontally slidably engaged with the frame. A horizontal cylinder is installed on the frame, and the end of the cylinder rod of the horizontal cylinder is connected to the temporary storage platform to drive the temporary storage platform to move on the frame.

[0010] Furthermore, the end of the tube loading robot is provided with a frame A, and two vacuum suction cups A are spaced apart on the frame A. The two vacuum suction cups A can respectively adsorb the two ends of the tube's periphery. Furthermore, the end of the connector loading robot is provided with a frame B, on which a connector end clamp and a vacuum suction cup B are sequentially arranged. Two vacuum suction cups B are spaced apart, and the two vacuum suction cups B can respectively adsorb the two ends of the tube body.

[0011] Furthermore, the connector end clamp includes a pneumatic finger and two clamping blocks.

[0012] Furthermore, a photoelectric switch with its detection end facing the clamping groove is installed on the clamping block.

[0013] The second technical solution adopted by the present invention to solve the technical problem is to provide a method for assembling a lower tube assembly, which uses the lower tube assembly device described above, and the specific steps are as follows: S1: The mold is opened, and the tube loading robot takes out the injection-molded tube; S2: The pipe feeding robot sends the end of the pipe with the sprue to the sprue assembly. S3: The cutter assembly cuts off the sprue on the pipe body; S4: The tube loading robot places the tube into the horizontal groove of the positioning fixture, with the tube assembly end facing the assembly push plate. S5: The connector end clamp of the connector loading robot picks up a connector and places it in the assembly position on the worktable, so that the assembly end of the connector faces the tube body. S6: The transverse component drives the assembly push plate, and the assembly push plate pushes the connector so that the connector is inserted into the tube body. S7: The vacuum suction cup B of the connector loading robot will take out the assembled lower tube assembly and send it to the collection station.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By coordinating the pipe feeding robot with the sprue assembly, the operation of automatically picking up products and automatically sprueing the nozzle is achieved.

Detailed Implementation

[0022] Preferred embodiments of the invention are described in more detail below; however, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the invention.

[0023] The lower tube assembly is an injection-molded part, consisting of a tube body and a tube connector. The tube body is connected to the sprue gate after injection molding. During the production of the lower tube assembly, the tube body and tube connector need to be pre-assembled to form the assembly. This includes removing the product from the injection molding machine cavity, trimming the sprue gate, and installing the lower tube connector. All of these operations are performed manually. Manual pre-assembly often results in incomplete sprue trimming and improper installation of the lower tube connector, easily leading to quality defects. Furthermore, it is inefficient, labor-intensive, and costly.

[0024] Example 1: To address the aforementioned issues, Embodiment 1 provides a lower tube assembly device to improve the automation level of the lower tube assembly operation, reduce quality abnormalities, and increase production efficiency.

[0025] like Figure 1-5 As shown, a pipe assembly assembly device includes an assembly base 6 and a cutter nozzle assembly 5. The assembly base 6 includes a workbench 11, on which a positioning fixture 12 and an assembly push plate 13 are provided. The positioning fixture 12 is provided with a transverse groove for placing the tube body 3, and one end of the transverse groove is closed. The assembly push plate 13 is located on the opening side of the transverse groove. The assembly push plate 13 is driven to move by the transverse moving assembly 14, which is mounted on the worktable 11. The transverse moving assembly 14 includes, but is not limited to, a cylinder, a hydraulic cylinder, or an electric push rod.

[0026] The cutter assembly 5 includes a pneumatic cutter 15 and a collection box 16 located below the pneumatic cutter 15. The pneumatic cutter 15 is mounted on one side of the workbench 11 via a bracket 17. The pneumatic cutter 15 can cut off the cutter on the pipe body 3 that has been moved to the cutting position. Due to gravity, the cutter will naturally fall into the collection box 16 below.

[0027] In this embodiment, a tube loading robot 2 is also included, which is disposed between the assembly base 6 and the injection molding machine 1.

[0028] In this embodiment, a connector loading robot 7 is also included, which is disposed between the assembly base 6 and the connector loading mechanism 8.

[0029] In this embodiment, the connector feeding mechanism 8 includes a frame 18 and a temporary storage platform 19. A bakelite fixture 20 is provided on the temporary storage platform 19. The bakelite fixture 20 has a plurality of slots 21 for storing connectors 4. A fixing clamp 23 for fixing the bakelite fixture 20 is provided on the temporary storage platform 19. By setting the fixing clamp 23, the bakelite fixture 20 can be replaced. By replacing it with other models of bakelite fixture 20, quick switching between machine models can be achieved. In actual use, the fixing clamp 23 includes an L-shaped positioning baffle and a side pressure cylinder located only on the two opposite sides of the L-shaped positioning baffle. The side pressure cylinder is perpendicular to the plate of the L-shaped positioning baffle located on its opposite side.

[0030] In this embodiment, the inner wall of the slot 21 is provided with an anti-reverse installation protrusion 22, which is adapted to the slot on the assembly end side of the connector 4. When the connector 4 is reversed, since the other end of the connector 4 does not have a matching slot, the anti-reverse installation protrusion 22 will block the end of the connector 4 from entering the slot 21. This design can prevent the product from being installed in reverse when the material is manually loaded into the slot 21.

[0031] In this embodiment, at least two temporary storage platforms 19 are provided. Each temporary storage platform 19 slides horizontally with the frame 18. A horizontal cylinder 24 is installed on the frame 18, and the cylinder rod end of the horizontal cylinder 24 is connected to the temporary storage platform 19 to drive the temporary storage platform 19 to move on the frame 18. The temporary storage platforms 19 and horizontal cylinders 24 are arranged in a one-to-one correspondence. One platform serves as a spare temporary storage platform 19 for storing material. Each time the connector loading robot 7 picks up a connector 4, it counts the number of connectors 4. When the count reaches a set value, there are no connectors 4 on that temporary storage platform 19. At this time, the horizontal cylinder 24 drives that temporary storage platform 19 to exit the loading station, while the other horizontal cylinder 24 drives the spare temporary storage platform 19 to move to the loading station. The worker places material on the temporary storage platform 19 that has exited the loading station and manually loads it into the slot 21 on the bakelite fixture 20. This design, utilizing a one-for-one backup principle, achieves uninterrupted material supply, eliminates processing waiting waste, and improves production efficiency.

[0032] In this embodiment, the end of the tube loading robot 2 is provided with a frame A9, and two vacuum suction cups A25 are spaced apart on the frame A9. The two vacuum suction cups A25 can respectively adsorb the two ends of the tube 3, and the tube 3 can be picked up and put down through the vacuum suction cups A25. In practical applications, the tube loading robot 2 is a three-axis robot or a three-axis linear module. The end of the tube loading robot 2 is connected to the lifting component 26 through a rotating joint. The frame A9 is connected to the lifting component 26. The rotating joint is driven by a cylinder or motor to rotate the frame A9 to control the frame A9 to be in a horizontal or vertical state. The lifting component 26 includes, but is not limited to, a cylinder, a hydraulic cylinder, and an electric push rod. The lifting component 26 is used to drive the frame A9 to rise and fall when the frame A9 is in a vertical state, so that the tube 3 enters or leaves the shearing station.

[0033] In this embodiment, the end of the connector loading robot 7 is provided with a frame B10. The frame B10 is sequentially provided with a connector end clamp and a vacuum suction cup B27. Two vacuum suction cups B27 are spaced apart. The two vacuum suction cups B27 can respectively adsorb the two ends of the periphery of the tube body 3. The tube body 3 can be picked up and put down through the vacuum suction cups B27. The connector end clamp can be used to pick up and put down the connector 4. The connector end clamp is used to clamp the connector 4 to the assembly seat 6 for assembly with the tube body 3. The vacuum suction cup B27 is used to adsorb the tube body 3 and take out the assembled lower tube assembly.

[0034] In this embodiment, the connector end clamp includes a pneumatic finger 28 and two clamping blocks 29. The two clamping blocks 29 are respectively installed on the two finger ends of the pneumatic finger 28, and clamping grooves for clamping the connector end are provided on the opposite sides of the two clamping blocks 29.

[0035] In this embodiment, a photoelectric switch with its detection end facing the clamping groove is installed on the clamping block 29. The photoelectric switch can determine whether there is a workpiece to be clamped. When the workpiece is reached at the joint loading clamping position, if the joint 4 is detected, it is clamped. If the joint 4 is not detected, the joint loading robot 7 moves the joint end clamp to the next joint placement area for detection again. If the joint 4 is still not detected at this time, the joint loading robot 7 stops its operation and alarms.

[0036] In this embodiment, all the electronically controlled components included in the device are electrically connected to the controller.

[0037] This device achieves automatic product loading and automatic nozzle cutting through the cooperation of the pipe loading robot 2 and the nozzle cutting assembly 5. Through the cooperation between the pipe loading robot 2, the joint loading robot 7, and the assembly base 6, this device can realize the automation of the assembly process, replacing manual assembly. This device can improve the automation level of the lower pipe assembly operation, reduce quality abnormalities, and improve production efficiency.

[0038] Example 2 Example 2 provides a method for assembling a lower tube assembly, which uses the lower tube assembly device in Example 1.

[0039] like Figure 6 As shown, the specific steps are as follows: S1: The mold is opened, and the tube loading robot 2 takes out the injection-molded tube 3; S2: The pipe feeding robot 2 delivers the end of the pipe 3 with the water outlet to the water outlet assembly 5; S3: The water outlet assembly 5 cuts off the water outlet on the pipe body 3; S4: The tube loading robot 2 places the tube 3 into the horizontal groove of the positioning fixture 12, with the assembly end of the tube 3 facing the assembly push plate 13. S5: The connector end clamp of the connector loading robot 7 picks up a connector 4 and places it in the assembly position of the workbench 11, so that the assembly end of the connector 4 faces the tube body 3. The assembly position is located between the assembly push plate 13 and the positioning fixture 12; When in the assembly position, the assembly end of the connector 4 is in contact with the assembly end of the pipe body 3, and the other end of the connector 4 abuts against the assembly push plate 13. S6: The transverse component 14 drives the assembly push plate 13, and the assembly push plate 13 pushes the connector 4 so that the connector 4 is inserted into the tube body 3, and the lower tube assembly is formed. S7: The vacuum suction cup B of the connector loading robot 7 will pick up the assembled lower tube assembly and send it to the collection station. In practical applications, finished product collection boxes or conveyor belts are set up at the collection station to collect products.

[0040] This method achieves automatic product picking and automatic nozzle cutting through the cooperation of the pipe loading robot 2 and the nozzle cutting assembly 5. Through the cooperation between the pipe loading robot 2, the joint loading robot 7, and the assembly base 6, the automated equipment can replace manual assembly. This method, together with the device provided in Embodiment 1, can improve the automation level of the lower pipe assembly operation, reduce quality abnormalities, and improve production efficiency.
