Description

Technical Field

[0001] The present invention relates to the technical field related to the assembly of pump heads, and specifically to a fully automatic assembly machine and an assembly method for an external pump head based on ultrasonic pressing. Background Art

[0002] In daily life, there are various items that require the use of pump heads, such as shampoo, shower gel, etc. Therefore, a large number of pump heads need to be produced. The production of pump heads usually requires multiple assembly processes, and large-scale production requires the use of assembly machines.

[0003] A Chinese authorized patent (Publication No.: CN220560841U), a pump head assembly device, includes a base, on which a pump head assembly table and a pump column assembly table are provided; a glass bead feeding mechanism is provided on the pump column assembly table, and the pump column assembly table is connected to a pump column feeding barrel and a spring feeding barrel; the outside of the pump head assembly table is provided with multiple layers of feeding layers, and each layer of feeding layer is evenly distributed with multiple feeding positions, and the feeding positions of each layer correspond one by one; the feeding positions of different layers are respectively connected to a pump core feeding barrel, a pump cover feeding barrel, and a lock cover feeding barrel. The pump column assembly table is connected to the pump head assembly table, and the pump column in the pump column assembly table enters the feeding position of the bottom layer through the pump column discharge track. There are multiple installation pins on the pump head assembly table, and the installation pins correspond to the feeding positions one by one. By setting up the pump head assembly table and the pump column assembly table at the same time, the pump head is assembled in two parts, the pump column is assembled in advance, and then the pump column is sent to the pump head assembly table, which speeds up the assembly efficiency, reduces the processing beat, and saves labor.

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

[0086] The special-shaped screw-threaded cap installation station 3 is used to install the special-shaped screw-threaded cap on the pump head body, and before installation, it detects the through-hole position of the special-shaped screw-threaded cap and automatically adjusts it so that the through-hole of the special-shaped screw-threaded cap is aligned with the pump head body;

[0087] The ultrasonic heat-sealing station 4 is used to thermally press and bond the special-shaped screw-threaded cap and the pump head body into one body;

[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 pressing station 6 is used to press the outer cover onto the pump head body so that the pump head body is snap-connected to the outer cover;

[0090] The rotating station 7 is used to threadedly tighten the five-piece set and the pump head body;

[0091] The pressing head installation station 8 is used to install the pressing head on the five-piece set;

[0094] Through the design of the automated mechanical structure and the coordinated work between each station, the present invention ensures that components such as the pump head body, the special-shaped screw-threaded cap, the outer cover, the five-piece set, and the pressing head can be accurately and quickly assembled together, realizing the fully automated assembly process of the pump head, and significantly improving the assembly efficiency and accuracy.

[0095] Please refer to Figure 2 , the pump head body feeding mechanism 2 includes:

[0096] A first sliding table 203, the first sliding table 203 is driven by a first two-dimensional moving member 202 installed on the workbench 1 to perform two-dimensional position transformation, and the first two-dimensional moving member 202 is installed on the workbench 1 through a first mounting frame 201;

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

[0098] A first feeding track 207, which is installed on the workbench 1 for the transportation of the pump head body;

[0099] A first conveying component disposed on the workbench 1, the first conveying component being configured to receive a single pump head body conveyed by the first loading track 207 and laterally convey the pump head body to the clamping position of the first clamping member 204.

[0100] Exemplarily, in one implementation, the first conveying component includes a first sliding seat 206 mounted on the workbench 1 and a first conveying table 205 slidably mounted on the first sliding seat 206. A first conveying groove for the pump head body to enter is formed on the first conveying table 205. A first cylinder 208 is further mounted on the first sliding seat 206, and the movable end of the first cylinder 208 is fixed to the first conveying table 205.

[0101] The first loading track 207 is connected to a vibrating loading tray. In the initial state, the first conveying groove is aligned with the first loading track 207. After the pump head body enters the first conveying groove, 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 body, the first two-dimensional moving member 202 drives the first clamping member 204 holding the pump head body to move to the assembly position closest to the pump head body feeding mechanism 2. Subsequently, the first clamping member 204 places the pump head body on the assembly position, realizing the feeding of the pump head body.

[0102] The entire feeding process has a high degree of automation, improving the feeding efficiency. At the same time, through the action of the first two-dimensional moving member 202, the pump head body can be accurately sent to the assembly position, ensuring the accuracy and stability of the assembly.

[0103] Please refer to Figure 3 , the special-shaped screw thread cover installation station 3 includes:

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

[0105] A second loading track 306, mounted on the workbench 1 for conveying the special-shaped screw thread cover;

[0106] A second conveying component movably disposed on the workbench 1, the second conveying component being configured to receive a single special-shaped screw thread cover conveyed by the second loading track 306 and convey the special-shaped screw thread cover to the clamping position of the second clamping member 304;

[0107] It further includes a detection head 305 communicating with the rotation driving member 303. The detection head 305 cooperates with the rotation driving member 303 to adjust the position of the through hole on the special-shaped screw thread cover.

[0108] Exemplarily, in one embodiment, the second conveying assembly includes a second sliding seat 308 mounted on the workbench 1. A second conveying table 307 is slidably mounted on the second sliding seat 308, and the second conveying table 307 is driven by a second air cylinder 309 mounted on the second sliding seat 308 to move and change positions.

[0109] A second conveying groove for the special-shaped screw cap to enter is formed on the second conveying table 307.

[0110] The second feeding track 306 is connected to another vibrating feeding tray. In the initial state, the second conveying groove is precisely aligned with the second feeding track 306. When the special-shaped screw cap smoothly enters the second conveying groove, the second air cylinder 309 is immediately started to push the second conveying table 307 to move precisely, ensuring that the special-shaped screw 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 rotation driving member 303 and the second clamping member 304 thereon to move downward, so that the second clamping member 304 can accurately clamp the special-shaped screw cap. After the clamping is completed, according to the precise feedback information provided by the detection head 305, the rotation driving member 303 guides the second clamping member 304 to make precise angle adjustments, ensuring that the through holes on the special-shaped screw cap can be perfectly aligned with the assembly holes on the pump head body during each assembly process, significantly improving the assembly efficiency of the special-shaped screw cap, and enhancing the accuracy and reliability of the assembly process.

[0111] Please refer to Figure 4 , the ultrasonic heat-sealing station 4 includes a third mounting frame 401 and a second sliding table 402 mounted on the third mounting frame 401 and capable of vertical movement. An ultrasonic heat-sealing head 403 facing the assembly position is mounted on the second sliding table 402.

[0112] In this embodiment, when the second sliding table 402 moves downward, it drives the ultrasonic heat-sealing head 403 to move downward synchronously, so as to contact the connection part between the pump head body and the special-shaped screw cap, realizing the heat-sealing connection between the pump head body and the special-shaped screw cap. In order to ensure the quality of the heat-sealing connection, the ultrasonic heat-sealing head 403 will emit ultrasonic vibrations after contacting the connection part. Through the heat energy generated by high-frequency vibrations, the contact surfaces of the pump head body and the special-shaped screw cap are quickly softened and fused to form a firm connection, improving the assembly efficiency of the special-shaped screw cap and the pump head body. At the same time, through hot pressing, the firmness of the installation of the pump head body and the special-shaped screw cap can be improved, and the quality of the assembled product is also ensured, providing a reliable guarantee for subsequent use and maintenance.

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

[0114] The third sliding seat 405 is further connected to a vertical adjusting member 406 mounted on the third mounting bracket 401. The vertical adjusting member 406 is used to adjust the vertical height of the third sliding seat 405, so as to finely adjust the initial position of the ultrasonic heat sealing head 403.

[0115] Exemplarily, in one implementation, the vertical adjusting member 406 includes a threaded rod passing through the third sliding seat 405 and threadedly connected to the third sliding seat 405, and a handwheel is fixed to the end of the threaded rod.

[0116] Please refer to Figure 5 , the outer cover and five-piece set installation station 5 includes:

[0117] A third loading track 504 and a fourth loading track 505 that are arranged vertically up and down and are respectively used for conveying the outer cover and the five-piece set. A through hole 509 for the outer cover to pass through is formed at the end of the travel of the third loading track 504;

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

[0119] A vertical pressing member 503 mounted on the workbench 1, which is used to press and place the outer cover on the five-piece set;

[0120] A third conveying component movably arranged on the workbench 1. The third conveying component is used to receive a single five-piece set conveyed by the fourth loading track 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 in one loading process to realize the preliminary nesting of the five-piece set and the outer cover, thereby reducing subsequent assembly processes, effectively improving production efficiency, and reducing production costs. Specifically, the outer cover and the five-piece set are respectively conveyed by the third loading track 504 and the fourth loading track 505, and the cooperation of the third two-dimensional moving member 502 and the vertical pressing member 503 is used to realize the precise alignment and pressing of the five-piece set and the outer cover, ensuring the stability and reliability of the nesting.

[0122] Exemplarily, the third conveying assembly includes a fourth sliding seat 506 installed on the workbench 1 and a third conveying table 508 slidably installed on the fourth sliding seat 506. A third conveying groove for receiving the five-piece set is formed on the third conveying table 508, and a third cylinder 507 for driving the third conveying table 508 to change its position is arranged on the fourth sliding seat 506.

[0123] The third feeding track 504 and the fourth feeding track 505 are respectively connected to two vibrating feeding trays. In the initial state, the third conveying groove is aligned with the fourth feeding track 505. After the five-piece set smoothly enters the third conveying groove, the vertical pressing member 503 is activated to convey the outer cover at the through hole 509 onto the five-piece set. Subsequently, the third cylinder 507 drives the third conveying table 508 to move, so that the five-piece set with the outer cover sleeved thereon moves to the clamping position of the third clamping member 510. The third two-dimensional moving member 502 drives the third clamping member 510 to move downward to clamp the outer cover and the five-piece set, and clamps and conveys the outer cover and the five-piece set to the assembly position, and places the five-piece set into the pump head body, thus completing the conveying.

[0124] Among them, the vertical pressing member 503 includes a cylinder or an electric telescopic rod. A pressing head is installed at the movable end of the cylinder or the electric telescopic rod. The pressing head is provided with negative pressure holes. When the pressing head contacts the outer cover, the outer cover can be adsorbed to the pressing head to ensure that the outer cover will not have the drawback of not being able to be sleeved on the five-piece set when moving downward. The negative pressure holes are connected to a negative pressure generator through a negative pressure pipeline. The negative pressure generator provides stable negative pressure suction to ensure that the pressing head can quickly and firmly adsorb the outer cover when contacting it. After the vertical pressing member 503 completes the pressing action, the third two-dimensional moving member 502 is immediately activated to accurately transfer the outer cover and the five-piece set to the next process. The entire conveying process is smooth and efficient.

[0125] Please refer to Figure 6 , the pressing station 6 includes:

[0126] A fifth mounting frame 601 installed on the workbench 1 and a third sliding table 603 slidably arranged on the fifth mounting frame 601. The third sliding table 603 is driven by a second vertical driving member 602 installed on the fifth mounting frame 601 to move up and down in the vertical direction;

[0127] A pressing member 604 is installed on the third sliding table 603, and the pressing surface of the pressing member 604 faces the turntable 10.

[0128] When the second vertical driving member 602 acts, it drives the third sliding table 603 to move vertically downward, so as to drive the pressing member 604 to act on the outer cover, thereby pressing and fixing the outer cover and the pump head body.

[0129] Please refer to Figure 7 , the rotating station 7 includes:

[0130] The sixth mounting bracket 701 installed on the workbench 1 and the fourth sliding table 702 slidably mounted on the sixth mounting bracket 701, and the fourth sliding table 702 is driven by a fourth air cylinder 703 installed on the sixth mounting bracket 701 to realize vertical up and down movement;

[0131] A rotary drive head 706 capable of extending into the five-piece set and engaging with the five-piece set;

[0132] A driving member installed on the fourth sliding table 702 and connected to the rotary drive head 706.

[0133] Exemplarily, in one embodiment, the driving member includes a motor 704 installed on the fourth sliding table 702, and the output shaft of the motor 704 is connected to the rotary drive head 706 through a transmission gear set 705. The fourth air cylinder 703 drives the fourth sliding table 702 to move downward, so that the rotary drive head 706 is inserted into the five-piece set and engaged with the five-piece set. Subsequently, the motor 704 drives the rotary drive head 706 to rotate through the transmission gear set 705 to drive the five-piece set to be screwed tightly onto the pump head body.

[0134] Preferably, the rotary drive head 706 is provided with protrusions to increase the stability of the engagement between the rotary drive head 706 and the five-piece set.

[0135] Through the above design, in the rotation station 7, the fourth air cylinder 703 serves as a vertical drive source, which not only realizes the overall downward movement of the fourth sliding table 702 and the motor 704, the transmission gear set 705 and the rotary drive head 706 installed on the fourth sliding table 702, ensures that the rotary drive head 706 can accurately insert 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, and then completes the process of screwing the five-piece set tightly onto the pump head body.

[0136] Please refer to Figure 8 and Figure 9 , the pressing head mounting station 8 includes:

[0137] A fifth sliding table 803, the fifth sliding table 803 is driven by a fourth two-dimensional moving member 802 installed on the workbench 1 to perform two-dimensional position transformation, a gripping head 804 for gripping the pressing head is installed on the fifth sliding table 803, and the fourth two-dimensional moving member 802 is installed on the workbench 1 through a seventh mounting bracket 801;

[0138] A fifth loading track 805 installed on the workbench 1;

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

[0140] Among them, the fourth conveying component includes a fifth sliding seat 807 installed on the workbench 1 and a fourth conveying table 806 slidably installed on the fifth sliding seat 807. The fourth conveying table 806 is driven by a fifth air cylinder 808 installed on the fifth sliding seat 807 to change its position, and a fourth conveying groove for the pressing head to enter is formed on the fourth conveying table 806.

[0141] The fifth feeding track 805 is connected to a vibrating feeding tray. 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 air cylinder 808 is immediately started to push the fourth conveying table 806 to move, so that the pressing head enters the grasping position of the grasping head 804. Subsequently, the fourth two-dimensional moving part 802 drives the grasping head 804 to assemble the pressing head.

[0142] During the assembly process, the grasping head 804 precisely clamps the pressing head to ensure that the pressing head can be accurately placed at the predetermined assembly position, improving the production efficiency and ensuring the assembly quality of the product at the same time.

[0143] Among them, it should be noted that the grasping head 804 is a negative pressure head, which grasps the pressing head by means of negative pressure adsorption. This not only improves the stability and accuracy of grasping, but also avoids damaging the pressing head during the grasping process. During the assembly process, the negative pressure head can firmly adsorb the pressing head to ensure that it will not fall off or shift during the movement and placement processes, thus ensuring the assembly accuracy and quality.

[0144] Please refer to Figure 10 , the blanking station 9 includes:

[0145] A sixth sliding table 903, which is driven by a fifth two-dimensional moving part 902 installed on the workbench 1 to perform two-dimensional position transformation.
