Description

Technical Field

[0001] This invention relates to the technical field of pump head assembly, specifically to an automated external pump head assembly machine and assembly method based on ultrasonic clamping. Background Technology

[0002] Pump heads are used in many everyday items, such as shampoo and shower gel, so they need to be mass-produced. Pump head production typically involves multiple assembly processes, and large-scale production requires assembly machines.

[0003] A Chinese patent (publication number: CN220560841U) discloses a pump head assembly device, comprising a base, a pump head assembly platform, and a pump column assembly platform. The pump column assembly platform is equipped with a glass bead feeding mechanism and connected to a pump column feeding hopper and a spring feeding hopper. The outer side of the pump head assembly platform has multiple feeding layers, each layer having multiple evenly distributed feeding positions, each corresponding to a specific feeding position. Different feeding positions in different layers are respectively connected to a pump core feeding hopper, a pump cover feeding hopper, and a lock cover feeding hopper. The pump column assembly platform is connected to the pump head assembly platform. The pump column within the pump column assembly platform enters the lowest feeding position via a pump column discharge track. The pump head assembly platform has multiple mounting pins, each corresponding to a feeding position. By simultaneously setting up the pump head assembly platform and the pump column assembly platform, the pump head is assembled in two parts. The pump column is assembled in advance before being fed into the pump head assembly platform, accelerating assembly efficiency, reducing processing cycle time, and saving manpower.

[0004] The press head of a conventional pump head is located in the middle of the irregular threaded cap, so only simple positioning assembly is required during assembly. However, the above assembly method can only be used for conventional pump heads and cannot be used for pump heads with irregular threaded caps, which has limitations. Summary of the Invention

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0080] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0081] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0082] This invention relates to the assembly of a pump head with a non-circular threaded cap. The pump head includes a pump head body, a non-circular threaded cap (i.e., a threaded cap with a mounting hole not in the center), an outer cover, a five-piece set, and a pressing head. After assembly, the pump head body passes through the through hole on the non-circular threaded cap and is fixed to the non-circular threaded cap. The five-piece set is inserted into the pump head body. The outer cover is fitted onto the pump head body at the position protruding from the outside of the non-circular threaded cap. The pressing head is inserted into the pump head body and connected to the five-piece set. The five-piece set includes a main column, a secondary column, a spring, a piston, and an outer shell.

[0083] Please see Figure 1 In this embodiment of the invention, the fully automatic assembly machine for an external pump head based on ultrasonic clamping includes a workbench 1 and a turntable 10 mounted on the workbench 1 and driven to rotate by a drive source. The turntable 10 has multiple assembly positions equidistantly installed. The machine also includes:

[0084] The pump head feeding mechanism 2, the irregular threaded cap installation station 3, the ultrasonic heat sealing station 4, the outer cover and five-piece set installation station 5, the pressing station 6, the rotating station 7, the pressing head installation station 8, and the unloading station 9 are installed on the workbench 1 and arranged sequentially around the turntable 10 along the assembly process.

[0085] The pump head body feeding mechanism 2 is used to transport the pump head body to the corresponding assembly position;

[0086] The irregular threaded cap installation station 3 is used to install the irregular threaded cap onto the pump head body, and to detect and automatically adjust the position of the through hole of the irregular threaded cap before installation so that the through hole of the irregular threaded cap is aligned with the pump head body.

[0087] The ultrasonic heat sealing station 4 is used to heat-press and bond the irregular threaded cap to the pump head body into one piece.

[0088] The outer cover and five-piece set installation station 5 is used to place the outer cover on the five-piece set and then insert it into the pump head body;

[0089] The clamping station 6 is used to press the outer cover onto the pump head body, so that the pump head body and the outer cover are engaged.

[0090] Rotary station 7 is used to screw the five-piece set to the pump head body thread;

[0091] Press head installation station 8 is used to install the press head onto the five-piece set;

[0092] Unloading station 9 is used to remove the assembled pump head.

[0093] In addition, a control system is included, which is electrically connected to the drive source, the pump head feeding mechanism 2, the irregular threaded cover installation station 3, the ultrasonic heat sealing station 4, the outer cover and five-piece set installation station 5, the pressing station 6, the rotating station 7, the pressing head installation station 8, and the unloading station 9, respectively, to control the operating sequence and time of each station in order to realize the automated assembly process.

[0094] This invention, through the design of an automated mechanical structure and the collaborative work between various workstations, ensures that components such as the pump head body, irregular threaded cap, outer cover, five-piece set, and pressing head can be accurately and quickly assembled together, realizing a fully automated assembly process for the pump head and significantly improving assembly efficiency and precision.

[0095] Please see Figure 2 The pump head body feeding mechanism 2 includes:

[0096] The first slide 203 is driven by the first two-dimensional moving part 202 mounted on the worktable 1 to perform two-dimensional position transformation. The first two-dimensional moving part 202 is mounted on the worktable 1 through the first mounting bracket 201.

[0097] A first clamping member 204 is installed on the first slide table 203;

[0098] The first feeding track 207 is installed on the workbench 1 for conveying the pump head body;

[0099] The first conveying assembly is set on the workbench 1. The first conveying assembly is used to receive a single pump head body conveyed by the first feeding rail 207 and to move the pump head body laterally to the clamping position of the first clamping member 204.

[0100] In one exemplary embodiment, the first conveying assembly includes a first slide 206 mounted on the workbench 1 and a first conveying table 205 slidably mounted on the first slide 206. The first conveying table 205 has a first conveying groove for the pump head body to enter. A first cylinder 208 is also mounted on the first slide 206, and the movable end of the first cylinder 208 is fixed to the first conveying table 205.

[0101] The first feeding track 207 is connected to the vibrating feeding plate. In the initial state, the first conveying trough is directly opposite the first feeding track 207. After the pump head enters the first conveying trough, the first cylinder 208 moves to push the first conveying table 205 to the clamping position. After the first clamping member 204 clamps the pump head, the first two-dimensional moving member 202 drives the first clamping member 204 holding the pump head to move to the assembly position closest to the pump head feeding mechanism 2. Then the first clamping member 204 places the pump head on the assembly position to realize the feeding of the pump head.

[0102] The entire feeding process is highly automated, which improves feeding efficiency. At the same time, through the action of the first two-dimensional moving part 202, the pump head body can be accurately delivered to the assembly position, ensuring the accuracy and stability of the assembly.

[0103] Please see Figure 3 The irregular threaded cap installation station 3 includes:

[0104] A rotation drive 303 is provided, and a second clamping member 304 is installed on the movable end of the rotation drive 303. The rotation drive 303 is driven by a second two-dimensional moving member 302 installed on the worktable 1 to perform two-dimensional position transformation. The second two-dimensional moving member 302 is installed on the worktable 1 through a second mounting bracket 301.

[0105] The second feeding track 306 is installed on the workbench 1 for conveying irregular threaded caps;

[0106] The second conveying assembly is set on the workbench 1. The second conveying assembly is used to receive a single irregular thread cap conveyed by the second feeding track 306 and convey the irregular thread cap to the clamping position of the second clamping member 304.

[0107] It also includes a detection head 305 that communicates with the rotation drive 303. The detection head 305 cooperates with the rotation drive 303 to adjust the position of the through hole on the irregular threaded cap.

[0108] For example, in one embodiment, the second conveying assembly includes a second slide 308 mounted on a worktable 1, a second conveying table 307 slidably mounted on the second slide 308, and the second conveying table 307 is driven to move and change position by a second cylinder 309 mounted on the second slide 308.

[0109] The second conveying table 307 has a second conveying groove for the entry of irregular threaded caps.

[0110] The second feeding track 306 is connected to another vibrating feeding plate. In the initial state, the second conveying groove is precisely aligned with the second feeding track 306. After the irregular threaded cap smoothly enters the second conveying groove, the second cylinder 309 is activated to push the second conveying table 307 to move precisely, ensuring that the irregular threaded cap can smoothly enter the predetermined clamping position of the second clamping member 304. Subsequently, the second two-dimensional moving member 302 precisely controls the rotating drive member 303 and the second clamping member 304 on it to move downward, so that the second clamping member 304 can accurately clamp the irregular threaded cap. After clamping, based on the precise feedback information provided by the detection head 305, the rotating drive member 303 guides the second clamping member 304 to make precise angle adjustments, ensuring that the through hole on the irregular threaded cap can be perfectly aligned with the assembly hole on the pump head body during each assembly process, which significantly improves the assembly efficiency of the irregular threaded cap and enhances the accuracy and reliability of the assembly process.

[0111] Please see Figure 4 The ultrasonic heat sealing station 4 includes a third mounting frame 401 and a second slide 402 mounted on the third mounting frame 401 and capable of vertical movement. An ultrasonic heat sealing head 403 is mounted on the second slide 402 and is directly opposite the assembly position.

[0112] In this embodiment, when the second slide 402 moves downward, it drives the ultrasonic heat sealing head 403 to move downward synchronously, thereby contacting the connection between the pump head body and the irregular threaded cap, realizing the heat sealing connection between the pump head body and the irregular threaded cap. In order to ensure the quality of the heat sealing connection, the ultrasonic heat sealing head 403 will emit ultrasonic vibration after contacting the connection point. The heat energy generated by the high-frequency vibration will quickly soften and fuse the contact surface between the pump head body and the irregular threaded cap, forming a firm connection. This improves the assembly efficiency of the irregular threaded cap and the pump head body. At the same time, the hot pressing can improve the firmness of the installation of the pump head body and the irregular threaded cap, and also ensure the quality of the assembled product, providing a reliable guarantee for subsequent use and maintenance.

[0113] Specifically, a third slide block 405 is slidably mounted on the third mounting bracket 401, and a second slide table 402 is slidably mounted on the third slide block 405 and connected to the movable end of the first vertical drive member 404 mounted on the third slide block 405. When the first vertical drive member 404 is activated, it drives the second slide table 402 to move, thereby driving the movement of the ultrasonic heat sealing head 403.

[0114] The third slide 405 is also connected to a vertical adjustment member 406 mounted on the third mounting bracket 401. The vertical adjustment member 406 is used to adjust the vertical height of the third slide 405, thereby enabling fine-tuning of the initial position of the ultrasonic heat sealing head 403.

[0115] In one exemplary embodiment, the vertical adjustment member 406 includes a threaded rod that passes through and is threadedly connected to the third slide 405, and a handwheel is fixed to the end of the threaded rod.

[0116] Please see Figure 5 The outer cover and five-piece assembly station 5 includes:

[0117] A third feeding track 504 and a fourth feeding track 505 are arranged vertically and are used to transport the outer cover and the five-piece set respectively. The third feeding track 504 has a passage hole 509 at the end of its stroke for the outer cover to pass through.

[0118] A third two-dimensional moving part 502 is installed on the workbench 1. The third two-dimensional moving part 502 is used to drive the third clamping part 510 connected thereto to perform two-dimensional position transformation. The third two-dimensional moving part 502 is installed on the workbench 1 through a fourth mounting bracket 501.

[0119] The vertical pressing component 503, installed on the workbench 1, is used to press the outer cover onto the five-piece set;

[0120] The third conveying assembly is set on the workbench 1. The third conveying assembly is used to receive a single five-piece set conveyed by the fourth feeding rail 505 and convey the five-piece set to the clamping position of the third clamping member 510.

[0121] In this embodiment, the five-piece set and the outer cover are integrated into a single feeding process, achieving initial fitting of the five-piece set and the outer cover. This reduces subsequent assembly processes, effectively improving production efficiency and lowering production costs. Specifically, the outer cover and the five-piece set are transported by the third feeding track 504 and the fourth feeding track 505, respectively. The precise alignment and pressing of the five-piece set and the outer cover are achieved through the cooperation of the third two-dimensional moving part 502 and the vertical pressing part 503, ensuring the stability and reliability of the fitting.

[0122] For example, the third conveying assembly includes a fourth slide 506 mounted on the workbench 1 and a third conveying table 508 slidably mounted on the fourth slide 506. The third conveying table 508 has a third conveying groove for receiving the five-piece set. The fourth slide 506 is provided with a third cylinder 507 for driving the third conveying table 508 to change position.

[0123] The third feeding track 504 and the fourth feeding track 505 are respectively connected to two vibrating feeding discs. In the initial state, the third conveying trough is aligned with the fourth feeding track 505. When the five-piece set enters the third conveying trough smoothly, the vertical pressing component 503 is activated to convey the outer cover at the through hole 509 onto the five-piece set. Then, the third cylinder 507 drives the third conveying table 508 to move, so that the five-piece set with the outer cover is moved to the clamping position of the third clamping component 510. The third two-dimensional moving component 502 drives the third clamping component 510 to move down to clamp the outer cover and the five-piece set, and clamps the outer cover and the five-piece set to the assembly position, and places the five-piece set into the pump head body, thereby completing the conveying.

[0124] The vertical pressing component 503 includes a cylinder or an electric telescopic rod. The movable end of the cylinder or electric telescopic rod is equipped with a pressing head. The pressing head is provided with a negative pressure hole. When the pressing head contacts the outer cover, it can attract the outer cover to the pressing head, ensuring that the outer cover will not be unable to be put on the five-piece set when it moves down. The negative pressure hole is connected to a negative pressure generator through a negative pressure pipeline. The negative pressure generator provides a stable negative pressure suction force, ensuring that the pressing head can quickly and firmly attract the outer cover when it contacts it. After the vertical pressing component 503 completes the pressing action, the third two-dimensional moving component 502 is immediately activated, accurately transferring the outer cover and the five-piece set to the next process. The entire conveying process is smooth and efficient.

[0125] Please see Figure 6 The pressing station 6 includes:

[0126] A fifth mounting bracket 601 is mounted on the workbench 1 and a third slide 603 is slidably mounted on the fifth mounting bracket 601. The third slide 603 is driven by a second vertical drive member 602 mounted on the fifth mounting bracket 601 to achieve vertical up and down movement.

[0127] A clamping member 604 is installed on the third slide table 603, with the clamping surface of the clamping member 604 facing the turntable 10.

[0128] When the second vertical drive member 602 is activated, it drives the third slide 603 to move vertically downward, thereby causing the clamping member 604 to act on the outer cover, thus clamping and fixing the outer cover to the pump head body.

[0129] Please see Figure 7 The rotating station 7 includes:

[0130] A sixth mounting bracket 701 is mounted on the workbench 1 and a fourth slide 702 is slidably mounted on the sixth mounting bracket 701. The fourth slide 702 is driven by a fourth cylinder 703 mounted on the sixth mounting bracket 701 to achieve vertical up and down movement.

[0131] The rotary drive head 706 is capable of extending into and engaging with the five-piece set.

[0132] The drive unit is mounted on the fourth slide 702 and connected to the rotary drive head 706.

[0133] In one exemplary embodiment, the driving component includes a motor 704 mounted on a fourth slide 702. The output shaft of the motor 704 is connected to the rotary drive head 706 via a transmission gear set 705. A fourth cylinder 703 drives the fourth slide 702 to move downward, causing the rotary drive head 706 to insert into and engage with the five-piece set. Subsequently, the motor 704 drives the rotary drive head 706 to rotate via the transmission gear set 705, thereby driving the five-piece set to be threaded tightly onto the pump head body.

[0134] Preferably, the rotary drive head 706 is provided with a protrusion, thereby increasing the stability of the rotary drive head 706 engaging with the five-piece set.

[0135] Through the above design, in the rotary station 7, the fourth cylinder 703, as a vertical drive source, not only realizes the overall downward movement of the fourth slide 702 and the motor 704, transmission gear set 705 and rotary drive head 706 mounted on the fourth slide 702, ensuring that the rotary drive head 706 can be accurately inserted into the five-piece set, but also realizes the rotation action of the rotary drive head 706 through the cooperation of the motor 704 and the transmission gear set 705, thereby completing the thread tightening process of the five-piece set on the pump head body.

[0136] Please see Figure 8 and Figure 9 The pressing head installation station 8 includes:

[0137] The fifth slide 803 is driven by the fourth two-dimensional moving part 802 installed on the worktable 1 to perform two-dimensional position transformation. The fifth slide 803 is equipped with a gripping head 804 for gripping by the pressing head. The fourth two-dimensional moving part 802 is installed on the worktable 1 through the seventh mounting bracket 801.

[0138] The fifth feeding track 805 is installed on workbench 1;

[0139] The fourth conveying assembly is set on the workbench 1. The fourth conveying assembly is used to receive a single pressing head conveyed by the fifth feeding track 805 and convey the pressing head to the gripping position of the gripping head 804.

[0140] The fourth conveying assembly includes a fifth slide 807 mounted on the worktable 1 and a fourth conveying table 806 slidably mounted on the fifth slide 807. The fourth conveying table 806 is driven by a fifth cylinder 808 mounted on the fifth slide 807 to change position. A fourth conveying groove is formed on the fourth conveying table 806 for the pressing head to enter.

[0141] The fifth feeding track 805 is connected to the vibrating feeding plate. In the initial state, the fourth conveying groove is aligned with the fifth feeding track 805. After the pressing head enters the fourth conveying groove, the fifth cylinder 808 is immediately started, pushing the fourth conveying table 806 to move, so that the pressing head enters the gripping position of the gripping head 804. Then, the fourth two-dimensional moving part 802 drives the gripping head 804 to assemble the pressing head.

[0142] During assembly, the gripper head 804 precisely clamps the pressing head, ensuring that the pressing head can be accurately placed in the predetermined assembly position, which improves production efficiency and guarantees the assembly quality of the product.

[0143] It should be noted that the gripping head 804 is a negative pressure head, which grips the pressing head by negative pressure adsorption. This not only improves the stability and accuracy of gripping, but also avoids damage to the pressing head during the gripping process. During assembly, the negative pressure head can firmly adsorb the pressing head, ensuring that it will not fall off or shift during movement and placement, thereby guaranteeing the accuracy and quality of assembly.

[0144] Please see Figure 10 The unloading station 9 includes:

[0145] The sixth slide 903 is driven by the fifth two-dimensional moving part 902 installed on the worktable 1 to perform two-dimensional position transformation. The sixth slide 903 is equipped with a fourth clamping part 904. After the fourth clamping part 904 clamps the assembled pump head, the pump head is taken out by the fifth two-dimensional moving part 902 to realize material unloading.

[0146] The fifth two-dimensional moving component 902 is mounted on the workbench 1 via the eighth mounting bracket 901.

[0147] In one embodiment of the present invention, a plurality of detectors 11 are equidistantly installed on the workbench 1 along the circumference of the turntable 10 to detect whether there is material at the work station. If there is material, the workbench is rotated to the next work station.

[0148] As another embodiment of the present invention, a fully automatic assembly method for an external pump head based on ultrasonic clamping is also proposed, which uses the aforementioned fully automatic assembly machine for an external pump head based on ultrasonic clamping, and includes the following steps:

[0149] The pump head body feeding mechanism 2 transports the pump head body to the corresponding assembly position;

[0150] The irregular threaded cap installation station 3 installs the irregular threaded cap onto the pump head body. Before installation, the position of the through hole of the irregular threaded cap is detected and automatically adjusted so that the through hole of the irregular threaded cap is aligned with the pump head body.

[0151] Ultrasonic heat sealing station 4 heat-presses the irregular threaded cap and the pump head body together into one piece.

[0152] At station 5, after placing the outer cover on the five-piece set, insert it into the pump head body.

[0153] Pressing station 6 presses the outer cover onto the pump head body, so that the pump head body and the outer cover are locked together;

[0154] Rotary station 7 tightens the five-piece set to the pump head body thread;

[0155] At station 8, the press head is installed onto the five-piece set.

[0156] At unloading station 9, the assembled pump head is removed.

[0157] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0158] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
