Description

Technical Field

[0001] This utility model relates to an automated assembly device for resin-filled tubes, which is applicable to the field of resin-filled tube processing technology. Background Technology

[0002] Resin-filled tubes are containers used for filling resin (as shown in the attached image). Figure 8 As shown), its structure and operating principle are similar to those of a syringe, typically consisting of a tube (attached). Figure 8 (As shown in reference numeral a), an end cap (attached) is placed on one end of the tube and has an adhesive outlet. Figure 8 (As shown in reference numeral c), the middle plug is slidably disposed inside the tube body and acts like a piston (attached). Figure 8 (As shown in reference numeral b), the push handle (attached) is inserted into the tube body from the other end and connected to the center bolt. Figure 8 The tube consists of four main components (as shown in reference d). In use, pushing the push handle drives the middle plug to squeeze the resin filling the tube body, extruding the resin from the outlet on the end cap. The processing method for the filled tube typically involves first molding the components through processes such as injection molding, then pre-assembling the tube body and middle plug to form a pre-assembled part, filling the tube body with resin, and finally assembling the end cap and push handle at the tube opening and tail of the pre-assembled part to form the final product.

[0003] The existing assembly process for filler tube pre-assemblies, end caps, and push handles is primarily completed manually on an assembly line. Pre-assemblies are transported to the production line with their tube openings facing upwards. Multiple production line workers then install end caps on these pre-assemblies. Subsequently, another assembly line transports pre-assemblies with end caps installed, ensuring their tails are facing upwards, and multiple production line workers then install push handles on these pre-assemblies. The output of this existing filler tube assembly method is entirely limited by the number of personnel. Improving production efficiency requires increasing the number of production line workers, but this incurs significant labor costs. Furthermore, manual assembly of end caps and push handles is prone to errors and inattention, leading to defective products or missing parts, severely impacting product yield and complicating subsequent quality control. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention proposes an automated assembly device for resin-filled tubes.

[0005] The technical solution adopted by this utility model is: an automated assembly device for resin-filled tubes, including a machine base, a first feeding mechanism for conveying end caps of the filling tubes, a second feeding mechanism for conveying pre-assembled components consisting of the tube body and the middle plug of the filling tube, a third feeding mechanism for conveying the push handle, and an assembly mechanism; the machine base is provided with a feeding station, a first assembly station, a second assembly station, and a processing station in sequence along the conveying direction of the workpiece in the assembly mechanism, and the discharge points of the first feeding mechanism, the second feeding mechanism, and the third feeding mechanism correspond to the feeding station, the first assembly station, and the second assembly station, respectively.

[0006] The assembly mechanism includes:

[0007] The fixing component includes a first clamp and a second clamp respectively disposed at the first assembly station and the second assembly station for fixing the pre-assembled parts;

[0008] The first mounting mechanism is located between the loading station and the first assembly station, and includes a first mounting jaw for holding the end cap, a first moving mechanism for driving the first mounting jaw to move so that the end cap is transferred from the loading station to the pre-assembled part in the first fixture, and a first rotating mechanism for driving the first mounting jaw to rotate so that the end cap is mounted on one end of the pre-assembled part.

[0009] The rotary transfer mechanism is located between the first assembly station and the second assembly station, and includes a transfer gripper for holding a pre-assembled part with an end cap installed, a second transfer mechanism for driving the transfer gripper to move, and a second rotation mechanism for driving the transfer gripper to rotate 180°.

[0010] The second mounting mechanism is located between the discharge point of the third feeding mechanism and the second assembly station. It includes a second mounting jaw for holding the push handle, a third moving mechanism for driving the second mounting jaw to move the push handle from the discharge point of the third feeding mechanism to the pre-assembled part in the second fixture, and a third rotating mechanism for driving the second mounting jaw to rotate so that the push handle is mounted on the other end of the pre-assembled part to form the product.

[0011] During the assembly of the filling tube, the pre-assembled component, consisting of the tube body and the middle plug, is first transferred to the first fixture via the second feeding mechanism. The pre-assembled component is then fixed in place by the first fixture, with its opening facing upwards. Next, the end cap is transported to the feeding station via the first feeding mechanism and held in place by the first mounting jaws. The first moving mechanism then drives the first mounting jaws to move the end cap onto the opening of the pre-assembled component in the first fixture. Finally, the first rotating mechanism drives the first mounting jaws to rotate, thus tightening the end cap onto the opening of the pre-assembled component, completing the assembly of the end cap and the pre-assembled component. The assembly process involves several steps: first, a pre-assembled component with end caps installed is held in the first fixture by a transfer gripper and transferred from the first fixture to the second fixture. During this transfer, a second rotating mechanism drives the pre-assembled component to rotate 180°, ensuring the tail of the component with end caps faces upwards and is fixed in the second fixture. After fixing, a third feeding mechanism transports the push handle to its discharge point. Then, a third moving mechanism drives the second mounting gripper to grab the push handle above the pre-assembled component in the second fixture. Finally, a third rotating mechanism drives the second mounting gripper to rotate, tightening the push handle into the central plug at the tail of the pre-assembled component, thus achieving automatic assembly of the filling tube product. Through the coordination of these mechanisms, the automatic assembly and processing of each component of the filling tube is achieved, saving significant labor costs and ensuring processing efficiency. Furthermore, by replacing manual operation with automated assembly, problems such as missing components and substandard quality caused by human factors are avoided, ensuring a high yield rate and reducing the difficulty of subsequent quality control. This also provides a foundation for the automation and unmanned operation of the entire production process.

[0012] Furthermore, the first feeding mechanism includes a first feeding assembly for supplying end caps, a blowing assembly for blowing the end caps, a first transfer gripper movably disposed between the first feeding assembly and the blowing assembly for transferring the end caps from the discharge port of the first feeding assembly to the blowing assembly, and a second transfer gripper movably disposed between the blowing assembly and the feeding station for transferring the end caps to the feeding station. The first feeding assembly conveys the end caps to their discharge port, and then the first transfer gripper picks up the end caps and places them at the blowing assembly to blow away any remaining foreign objects or dust from the end caps, facilitating subsequent installation. After blowing is completed, the second transfer gripper transfers the end caps to the feeding station for the first installation gripper to pick them up.

[0013] Furthermore, the first feeding assembly includes a first vibrating disc, a first feeding trough connected at one end to the first vibrating disc, and a first transfer member horizontally slidably disposed at the other end of the first feeding trough. The first transfer member has a first receiving groove for accommodating end caps on the side facing the first feeding trough. The first transfer member has at least two working positions by sliding. When it is in the first working position, the first receiving groove is opposite to the other end of the first feeding trough. When the first transfer member is in the second working position, the first transfer member is located at the discharge point of the first feeding assembly. The end caps are fed by vibration from the first vibrating disc, causing them to adjust to a specific posture during vibration and enter the first feeding trough sequentially from one end. When the foremost end cap moves along the first feeding trough to its other end, the first transfer member is in the first working position so that the foremost end cap enters the first receiving groove. Then, the first transfer member moves to the second working position, separating the foremost end cap from the other end caps, making it easier for the first transfer gripper to grab the end cap from the first transfer member.

[0014] Furthermore, the purging assembly includes a fixed base mounted on the machine platform for placing the end cap, and an air blowing pipe positioned above the fixed base for blowing high-pressure airflow onto the end cap. Specifically, the air blowing pipe is connected to an external high-pressure air source, and high-pressure airflow is blown onto the end cap on the fixed base through the air blowing pipe to blow away residual debris and foreign objects in the end cap, so as to avoid affecting subsequent assembly.

[0015] Furthermore, the second feeding mechanism includes a pre-inspection component mounted on the machine base for inspecting pre-assembled parts, a third transfer gripper movably positioned between the pre-inspection component and the first assembly station for transferring pre-assembled parts to the first fixture, and a waste box mounted on the machine base and located below the movement path of the third transfer gripper. In actual production, after the tube body and the middle plug of the filling tube are assembled, resin filling is performed on them, followed by the assembly of the end cap and the push handle. Therefore, in actual production, the pre-assembled parts in this solution are already filled with resin. The pre-inspection component can inspect the filling status of the pre-assembled parts to ensure that the quality of the pre-assembled parts transported to the assembly mechanism is qualified. The inspected pre-assembled parts are transported to the first fixture via the third transfer gripper. When the inspection result of the pre-inspection component is unqualified, the third transfer gripper will throw the unqualified product into the waste box when passing over it, thus realizing the transportation of pre-assembled parts and the sorting of good and bad products. Specifically, the second feeding mechanism can be connected to the resin filling equipment. The unloading robot in the resin filling equipment places the pre-assembled parts that have been filled into the pre-inspection assembly, so as to realize the automated processing of filling and assembly.

[0016] Furthermore, the pre-inspection component includes a weighing platform, a vision inspection device, and a fourth transfer gripper movably positioned between the weighing platform and the vision inspection device for transferring the pre-assembled parts on the weighing platform to the vision inspection device. A third transfer gripper transfers the pre-assembled parts from the vision inspection device to a first fixture. Weighing the pre-assembled parts on the weighing platform allows for verification of the resin content, and the vision inspection device then checks the resin filling status to prevent overflow and ensure the quality of the pre-assembled parts. The fourth transfer gripper facilitates the transfer of the pre-assembled parts.

[0017] Furthermore, the third feeding mechanism includes a second vibrating disc, a second feeding trough connected at one end to the second vibrating disc, and a second transfer member located at the discharge point of the third feeding mechanism, with one end rotatably arranged around a horizontally arranged rotating shaft and the other end having a second receiving groove for accommodating a push rod. The second transfer member has at least two working positions by rotation. When it is in the first working position, the second transfer member is horizontally arranged, and the second receiving groove is connected to the other end of the second feeding trough. When the second transfer member is in the second working position, the second transfer member is vertically arranged, and the second receiving groove is located at the discharge point of the third feeding mechanism. The material is fed by vibration from the second vibrating disc, causing the push handle to adjust itself to a specific posture during vibration and enter the second feeding groove sequentially from one end. When the foremost push handle moves along the second feeding groove to its other end, the second transfer member is in the first working position so that the foremost push handle can enter the second receiving groove. Then the second transfer member rotates to the second working position so that the push handle rotates to face the second mounting claw, so that the second mounting claw can grasp the push handle and assemble it.

[0018] Furthermore, the assembly mechanism also includes a capping assembly located at the processing station for capping the end cap, and a fifth transfer gripper movably positioned between the second assembly station and the processing station for transferring the product in the second fixture to the capping assembly. The capping assembly is used to cap the end cap, which has a body and a cap and a structure similar to a toothpaste cap, thereby improving the production process of the filling tube and achieving automated production of the filling tube.

[0019] Furthermore, the cap assembly includes a pair of actuating claws that are movably mounted on the machine base and can be closed or opened relative to each other to move the cap body of the end cap to engage with the main body of the end cap; a push rod that is movably mounted on the sides of the pair of actuating claws and used to push the cap body to engage with the main body; and a fixing claw that is movably mounted between the pair of actuating claws and the push rod and used to clamp and fix the product between the pair of actuating claws or above the push rod. Each of the opposing sides of the pair of actuating claws has a semi-circular third receiving groove. When the pair of actuating claws are closed relative to each other, the third receiving grooves on the pair of actuating claws form a complete circle, and the diameter of this circle is larger than the diameter of the main body but smaller than the sum of the diameters of the main body and the cap body. The assembled product is transferred to the cap assembly via the fifth transfer gripper and clamped by the fixed gripper. At this point, the product is in an upright position with the end cap facing downwards. Subsequently, a pair of actuating grippers open relative to each other, facilitating the fixed gripper to move the product between the third receiving slots of the pair of actuating grippers. Then, the pair of actuating grippers close and move downwards. Since the diameter of the circle formed by the third receiving slot is smaller than the sum of the diameters of the body and the cap, as the pair of actuating grippers move downwards, the cap of the end cap abuts against the bottom of the actuating grippers as the actuating grippers move, and overlaps with the body of the end cap under the actuating grippers' actuation. Then, the fixed gripper moves the product above the push rod, and the push rod moves upwards to push the cap, causing it to lock into place with the end cap body, thereby achieving the end cap closing process.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] The automated resin-filled tube assembly device of this utility model achieves automatic assembly and processing of various components of the filling tube through the cooperation of various feeding mechanisms and assembly mechanisms. This not only saves a lot of labor costs and ensures processing efficiency, but also avoids problems such as missing products and substandard quality caused by human factors by replacing manual operation through automated assembly, thus ensuring the product yield rate, reducing the difficulty of subsequent quality control, and providing a foundation for the automation and unmanned operation of the entire production process.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In the description of this utility model, it should be noted that the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, the technical features involved in the different embodiments of this utility model described below may be combined with each other as long as they do not conflict with each other.

[0035] Reference Appendix Figure 1-8 The automated resin-filled tube assembly device in this embodiment includes a machine base 1, a first feeding mechanism 2 for conveying the end caps of the filling tubes, a second feeding mechanism 3 for conveying the pre-assembled parts composed of the tube body and the middle plug of the filling tubes, a third feeding mechanism 4 for conveying the push handle, and an assembly mechanism 5. The machine base 1 is provided with a feeding station, a first assembly station, a second assembly station, and a processing station in sequence along the conveying direction of the processed parts in the assembly mechanism 5. The discharge points of the first feeding mechanism 2, the second feeding mechanism 3, and the third feeding mechanism 4 correspond to the feeding station, the first assembly station, and the second assembly station, respectively.

[0036] Assembly mechanism 5 includes:

[0037] The fixing component 51 includes a first clamp 511 and a second clamp 512 respectively disposed at the first assembly station and the second assembly station for fixing the pre-assembled parts; the first clamp 511 and the second clamp 512 fix the pre-assembled parts located at the assembly station, which facilitates the assembly operation of the end cap and the push handle.

[0038] The first mounting mechanism 52 is located between the loading station and the first assembly station. It includes a first mounting jaw 521 for holding the end cap, a first moving mechanism 522 for driving the first mounting jaw 521 to move so that the end cap is transferred from the loading station to the pre-assembled part in the first fixture 511, and a first rotating mechanism 523 for driving the first mounting jaw 521 to rotate so that the end cap is mounted on one end of the pre-assembled part. Specifically, the first moving mechanism 522 is a three-axis slide table to drive the first mounting jaw 521 to move, and the first rotating mechanism 523 is a servo motor with its rotation axis set in the vertical direction to drive the first mounting jaw 521 to rotate. In actual production, the end cap is conveyed to the loading station with the end connected to the pre-assembled part facing down. After the first mounting jaw 521 moves horizontally above the end cap, it moves down and clamps the upper part of the end cap. After clamping and fixing, it moves up to a certain height and then moves horizontally to move the end cap above the pre-assembled part. Then, the first mounting jaw 521 moves down to make the end cap contact the tube opening of the pre-assembled part. Then, the first rotating mechanism 523 drives the first mounting jaw 521 to rotate and tighten the end cap onto the tube opening of the pre-assembled part.

[0039] The rotary transfer mechanism 53 is located between the first assembly station and the second assembly station. It includes a transfer gripper 531 for holding a pre-assembled part with an end cap, a second transfer mechanism 532 for driving the transfer gripper 531 to move, and a second rotation mechanism 533 for driving the transfer gripper 531 to rotate 180°. Specifically, the second transfer mechanism 532 is a two-axis slide table, which facilitates the transfer gripper 531 to transport the pre-assembled part between the first assembly station and the second assembly station. The second rotation mechanism 533 is a servo motor, and its rotation axis is set in the horizontal direction to drive the transfer gripper 531 to rotate. In actual production, the pre-assembled part in the first fixture 511 is in a vertical position with the tube opening facing upward. When the transfer gripper 531 transfers it to the second fixture 512, the transfer gripper 531 will rotate 180° under the drive of the second rotation mechanism 533, so that the pre-assembled part is fixed in the second fixture 512 in a vertical position with the tail facing upward, which is convenient for subsequent assembly processing.

[0040] The second mounting mechanism 54 is disposed between the discharge point of the third feeding mechanism 4 and the second assembly station. It includes a second mounting jaw 541 for clamping the push handle, a third moving mechanism 542 for driving the second mounting jaw 541 to move the push handle from the discharge point of the third feeding mechanism 4 to the pre-assembled part in the second fixture 512, and a third rotating mechanism 543 for driving the second mounting jaw 541 to rotate so that the push handle is mounted on the other end of the pre-assembled part to form a product. Specifically, the third moving mechanism 542 is configured as a three-axis slide table, and the third rotating mechanism 543 is configured as a servo motor, with its rotation axis set vertically. In actual production, when the push handle is conveyed to the discharge point of the third feeding mechanism 4, it is in a vertical state, with the end of the push handle connected to the pre-assembled part facing downwards. The second mounting jaw 541 moves horizontally above the push handle, then moves downwards and clamps the upper end of the push handle. Then, driven by the third moving mechanism 542, the push handle moves upwards and horizontally above the second clamp 512. Subsequently, the second mounting jaw 541 moves downwards so that the lower end of the push handle contacts the tail of the pre-assembled part. Then, the third rotating mechanism 543 drives the second mounting jaw 543 to rotate, rotating and installing the push handle into the tail of the pre-assembled part.

[0041] During the assembly of the filling tube, the pre-assembled component, consisting of the tube body and the middle plug, is first transferred to the first clamp 511 via the second feeding mechanism 3. The pre-assembled component is then fixed in place by the first clamp 511, with the tube opening facing upwards. Next, the end cap is transported to the feeding station via the first feeding mechanism 2 and held in place by the first mounting jaw 521. The first moving mechanism 522 then drives the first mounting jaw 521 to move the end cap onto the tube opening of the pre-assembled component in the first clamp 511. Finally, the first rotating mechanism 523 drives the first mounting jaw 521 to rotate, thus tightening the end cap onto the tube opening of the pre-assembled component, completing the connection between the end cap and the pre-assembled component. The assembly of the components is as follows: then, the pre-assembled component with end caps installed in the first clamp 511 is held by the transfer gripper and transferred from the first clamp 511 to the second clamp 512. During the transfer, the pre-assembled component is rotated 180° by the second rotation mechanism 533 so that the tail of the pre-assembled component with end caps is facing upward and is fixed in the second clamp 512. After fixing, the push handle is conveyed to its discharge point by the third feeding mechanism 4. Then, the second mounting gripper 541 is driven by the third moving mechanism 542 to grab the push handle above the pre-assembled component in the second clamp 512. Then, the second mounting gripper 541 is driven by the third rotation mechanism 543 to rotate and tighten the push handle into the middle plug at the tail of the pre-assembled component, thereby realizing the automatic assembly of the filling tube product. Through the cooperation of the above-mentioned mechanisms, the automatic assembly and processing of each component of the filling tube can be achieved, which not only saves a lot of labor costs, but also ensures processing efficiency. Furthermore, by replacing manual operation with automated assembly, problems such as missing parts and substandard quality caused by human factors are avoided, ensuring the yield rate of products, reducing the difficulty of subsequent quality control, and providing a foundation for the automation and unmanned operation of the entire production process.

[0042] In a more preferred embodiment, the first feeding mechanism 2 includes a first feeding assembly 21 for supplying end caps, a blowing assembly 22 for blowing the end caps, a first transfer gripper 23 movably disposed between the first feeding assembly 21 and the blowing assembly 22 for transferring the end caps from the discharge port of the first feeding assembly 21 to the blowing assembly 22, and a second transfer gripper 24 movably disposed between the blowing assembly 22 and the feeding station for transferring the end caps to the feeding station. The end caps are conveyed to their discharge port by the first feeding assembly 21, and then the end caps are gripped by the first transfer gripper 23 and placed at the blowing assembly 22 to blow away any foreign matter or dust remaining in the end caps, facilitating subsequent installation. After blowing, the end caps are transferred to the feeding station by the second transfer gripper 24 for gripping by the first installation gripper 521.

[0043] In a more preferred embodiment, the first feeding assembly 21 includes a first vibrating disc 211, a first feeding trough 212 connected at one end to the first vibrating disc 211, and a first transfer member 213 horizontally slidably disposed at the other end of the first feeding trough 212. The first transfer member 213 has a first receiving groove 214 for accommodating an end cap on one side facing the first feeding trough 212. The first transfer member 213 has at least two working positions by sliding. When it is in the first working position, the first receiving groove 214 is connected to the other end of the first feeding trough 212. When the first transfer member 213 is in the second working position, the first transfer member 213 is located at the discharge point of the first feeding assembly 21. The end caps are fed by vibration from the first vibrating disc 211, causing them to adjust to a specific posture during vibration and enter the first feeding trough 212 sequentially from one end. When the foremost end cap moves to the other end of the first feeding trough 212, the first transfer member 213 is in a first working position, allowing the foremost end cap to enter the first receiving groove 214. Then, the first transfer member 213 moves to a second working position, separating the foremost end cap from the other end caps, facilitating the first transfer gripper 23 to pick up the end cap from the first transfer member 213. It should be noted that the end caps enter the first feeding trough 212 from the first vibrating disc 211 in a specific posture, i.e., the end of the end cap connected to the pre-loaded component faces downwards. The first vibrating disc 211 is designed to achieve the above function using a vibrating feeding mechanism that allows materials to be discharged in a specific posture or direction, as is available in the prior art.

[0044] In a more preferred embodiment, the purging assembly 22 includes a fixed base 221 fixedly mounted on the machine base 1 for placing the end cap, and an air blowing pipe 222 disposed above the fixed base 221 for blowing high-pressure airflow onto the end cap. Specifically, the air blowing pipe 222 is connected to an external high-pressure air source. High-pressure airflow is blown onto the end cap on the fixed base 221 through the air blowing pipe 222 to blow away residual debris and foreign matter in the end cap, so as to avoid affecting subsequent assembly.

[0045] In a more preferred embodiment, the second feeding mechanism 3 includes a pre-inspection component 31 disposed on the machine base 1 for inspecting pre-assembled parts, a third transfer gripper 32 movably disposed between the pre-inspection component 31 and the first assembly station for transferring pre-assembled parts into the first fixture 511, and a waste box 33 disposed on the machine base 1 and located below the movement path of the third transfer gripper 32. In actual production, after the tube body and middle plug of the filling tube are assembled, resin filling is performed, followed by the assembly of the end cap and push handle. Therefore, the pre-assembled parts mentioned in this article are already filled with resin. The filling status of the pre-assembled parts can be detected by the pre-inspection component 31 to ensure that the quality of the pre-assembled parts transported to the assembly mechanism is qualified. The pre-assembled parts that have been inspected are transported to the first fixture by the third transfer gripper 32. When the inspection result of the pre-inspection component is unqualified, the third transfer gripper 32 will throw the unqualified part into the waste box 33 when it passes over the waste box 33, realizing the transportation of pre-assembled parts and the sorting of good and bad products. Specifically, the second feeding mechanism 3 can be connected to the resin filling equipment. The unloading robot in the resin filling equipment places the pre-assembled parts that have been filled into the pre-inspection component to realize the automated processing of filling and assembly.

[0046] In a more preferred embodiment, the pre-inspection component 31 includes a weighing platform 311, a vision inspection device 312, and a fourth transfer gripper 313 movably disposed between the weighing platform 311 and the vision inspection device 312 for transferring the pre-assembled parts on the weighing platform 311 to the vision inspection device 312. The third transfer gripper 32 transfers the pre-assembled parts from the vision inspection device 312 to the first clamp 511. The pre-assembled parts are weighed by the weighing platform 311 to check whether the amount of resin filled in the pre-assembled parts meets the standard. Then, the vision inspection device 312 checks the filling status of the resin in the pre-assembled parts to avoid problems such as overflow, thereby ensuring the quality of the pre-assembled parts. The fourth transfer gripper 313 can realize the transfer of the pre-assembled parts.

[0047] In a more preferred embodiment, the third feeding mechanism 4 includes a second vibrating disc 41, a second feeding trough 42 connected at one end to the second vibrating disc 41, and a second transfer member 43 located at the discharge point of the third feeding mechanism 4, with one end rotatably arranged about a horizontally arranged rotating shaft and the other end having a second receiving groove 431 for accommodating a push rod. The second transfer member 43 has at least two working positions by rotation. When it is in the first working position, the second transfer member 43 is horizontally arranged, and the second receiving groove 431 is connected to the other end of the second feeding trough 42. When the second transfer member 43 is in the second working position, the second transfer member 43 is vertically arranged, and the second receiving groove 431 is located at the discharge point of the third feeding mechanism 4. The material is fed by vibration from the second vibrating disc 41, causing the push handle to adjust itself to a specific posture during vibration and enter the second feeding groove 42 sequentially from one end. When the foremost push handle moves along the second feeding groove 42 to its other end, the second transfer member 43 is in the first working position so that the foremost push handle enters the second receiving groove 431. Then the second transfer member 43 rotates to the second working position so that the push handle rotates to face the second mounting claw 541, so that the second mounting claw 541 can grasp the push handle and assemble it.

[0048] In a more preferred embodiment, the assembly mechanism 5 further includes a capping assembly 55 disposed at the processing station for capping the end cap, and a fifth transfer gripper 56 movably disposed between the second assembly station and the processing station for transferring the product in the second clamp 512 to the capping assembly 55. The capping assembly 55 is used to cap the end cap, which has a body and a cap and a structure similar to a toothpaste cap, thereby improving the production process of the filling tube and achieving automated production of the filling tube.

[0049] In a more preferred embodiment, the cap assembly 55 includes a pair of actuating claws 551 that are movably disposed on the machine base 1 and can be closed or opened relative to each other, for moving the cap body of the end cap to engage with the body of the end cap; a push rod 552 that is movably disposed on the side of the pair of actuating claws 551 and is used to push the cap body to engage with the body; and a fixing claw 553 that is movably disposed between the pair of actuating claws 551 and the push rod 552 and is used to clamp and fix the product between the pair of actuating claws 551 or above the push rod 552. The opposite sides of the pair of actuating claws 551 are provided with a semi-circular third receiving groove 554. When the pair of actuating claws 551 are closed relative to each other, the third receiving grooves 554 located on the pair of actuating claws 551 respectively form a complete circle, and the diameter of the circle is larger than the diameter of the body and smaller than the sum of the diameters of the body and the cap body. The assembled product is transferred to the cap assembly 55 by the fifth transfer gripper 56, and the product is clamped by the fixed gripper 553. At this time, the product is in a vertical position with the end cap facing down. Then, a pair of actuating claws 551 open relative to each other, so that the fixed gripper 553 can move the product between the third receiving grooves 554 of the pair of actuating claws 551. Then, the pair of actuating claws 551 close and move downward. Since the diameter of the circle formed by the third receiving groove 554 is smaller than the sum of the diameters of the body and the cap, when the pair of actuating claws 551 move downward, the cap of the end cap will abut against the bottom of the actuating claws 551 as the actuating claws 551 move, and will overlap with the body of the end cap under the actuation of the actuating claws 551. Then, the fixed gripper 553 moves the product above the push rod 552, and pushes the cap by the upward movement of the push rod 552, so that it is locked with the end cap body, thereby realizing the end cap closing process.
