Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 and Figure 2 The pump body 1 has the largest dimensions in the middle, and smaller dimensions at the top and bottom. The pressure head 2 and the protective sleeve 3 are similar in shape, both having a cylindrical structure and a trapezoidal structure on the outside of the cylindrical structure. The protective sleeve 3 has an opening on one side to facilitate the insertion of the pressure head 2 through the opening. After assembly, the pressure head 2 is located at the top of the pump body 1, and the protective sleeve 3 is located at the bottom of the pressure head 2.

[0023] Reference Figure 3 , Figure 4 and Figure 5 The tooth-locking machine of this utility model embodiment includes a turntable mechanism 900, a mold base 910, a pump body station 100, a glass ball inspection station 200, a pressure head station 300, a pump inspection station 400, a tooth-locking station 500, a sheath station 600, a discharge station 700, and a defective product station 800. The mold base 910 is mounted on the turntable mechanism 900, which drives the mold base 910 to rotate sequentially to different stations. The mold base 910 has mounting holes, which are through holes with the same shape as the middle part of the pump body 1. The upper and lower ends of the pump body 1 protrude from the mounting holes, and the mold base 910 is stepped, meaning the lower dimension of the mold base 910 is smaller than the upper dimension, thereby supporting the pump body 1 and preventing it from falling out of the mounting holes.

[0024] Pump body station 100 serves as the initial process, responsible for precisely transferring pump body 1 to mold base 910, providing a basic carrier for subsequent assembly. Then, mold base 910, with pump body 1 on it, rotates to glass ball detection station 200. At glass ball detection station 200, pressing the upper end of pump body 1 connects the internal piston of pump body 1. A first negative pressure detection device is then connected to the lower end of pump body 1, and by activating the first negative pressure detection device, negative pressure is drawn to detect the presence of glass balls inside pump body 1. Next, mold base 910, with pump body 1 on it, rotates to pressure head station 300, where pressure head 2 is placed at the end of pump body 1 on mold base 910, achieving initial fixation and positioning of pressure head 2 and pump body 1. The mold base 910, containing the pump body 1 and pressure head 2, continues to rotate to the pump testing station 400. A pressure gauge is connected to the lower end of the pump body 1, and the pressure head 2 is pressed down simultaneously to create negative pressure inside the pump body 1. The pressure gauge reading is used to determine if the pump output of the pump body 1 meets the pumping performance requirements. The mold base 910 continues to rotate to the locking station 500, where the pressure head 2 is rotated to lock it relative to the pump body 1. The mold base 910 continues to rotate to the sheath station 600, where the sheath 3 is installed below the pressure head 2. After the pump assembly is complete, it reaches the discharge station 700. If all previous tests meet the process requirements, the pump is removed from the discharge station 700 and transported to the next process. If any test fails, the pump continues from the discharge station 700 to the defective product station 800, where the corresponding part is removed from the mold base 910.

[0025] Understandably, the glass ball inside pump body 1 acts as a one-way valve core to restrict the direction of fluid flow. When one of the defects is detected, the product on the corresponding mold base 910 is not further assembled, which allows for early detection of problems, avoids unnecessary assembly and disassembly work, and improves work efficiency. For example, when the glass ball detection station 200 detects that there is no glass ball inside pump body 1, the system automatically marks the mold base 910 as a defective product. Subsequent stations (pressure head 2 installation, thread locking, etc.) skip this process and do not assemble pressure head 2 and sheath 3, directly proceeding to the defective product removal process.

[0026] It should be noted that glass ball inspection station 200, pump inspection station 400, material discharge station 700, and defective product station 800 are not necessary stations in the assembly process and can be added or removed according to actual needs.

[0027] The key processes are described in detail below.

[0028] Reference Figure 4It is understood that the pump body station 100 is equipped with a first vibratory feeder 110, a first positioning mechanism, a first mechanical clamp, and a first conveying mechanism 120. The first vibratory feeder 110 is used to supply pump bodies 1. The function of the first vibratory feeder 110 is to organize the disordered pump bodies 1 into an ordered queue through vibration and convey them along the material channel. The first positioning mechanism is used to position the pump bodies 1 at the end of the material channel of the first vibratory feeder 110. The first positioning mechanism can be set as a positioning plate with positioning grooves. The pump bodies 1 of the first vibratory feeder 110 enter the positioning grooves on the positioning plate in sequence to achieve positioning. The first mechanical clamp is used to clamp the pump bodies 1. The first conveying mechanism 120 is used to drive the first mechanical clamp to rise to remove the pump bodies 1. The first conveying mechanism 120 is also used to drive the first mechanical clamp to move horizontally to send the pump bodies 1 above the mold base 910 and drive the first mechanical clamp to fall. After the first mechanical clamp is released, the pump bodies 1 enter the mold base 910. The first conveying mechanism 120 may include a first cylinder and a second cylinder. The first cylinder is used to drive the first mechanical clamp to rise and fall, and the second cylinder is used to drive the first mechanical clamp to move in the horizontal direction.

[0029] The glass ball testing station 200 is equipped with a third cylinder, a fourth cylinder, and a first negative pressure testing device. The third cylinder presses down on the upper end of the pump body 1, activating the internal piston and creating conditions for subsequent negative pressure testing. The fourth cylinder rises, causing the first negative pressure testing device to seal against the lower end of the pump body 1, forming a closed space. When the first negative pressure testing device is activated, negative pressure is drawn. If a glass ball is present in the pump body 1, the glass ball will block the channel due to the negative pressure, creating a stable negative pressure within the closed space. If no glass ball is present, negative pressure cannot be formed in the closed space, thus the test is deemed unqualified.

[0030] Reference Figure 4 The pressing station 300 is equipped with a second vibrating plate 310, a second positioning mechanism, a first suction cup mechanism, and a second conveying mechanism 320. The second vibrating plate 310 supplies the pressing heads 2. The vibration of the second vibrating plate 310 organizes the disordered pressing heads 2 into an ordered queue, and then stably conveys them to the end of the station through a direct vibration material channel. The second positioning mechanism is used to position the pressing heads 2 at the end of the material channel of the second vibrating plate 310. The second positioning mechanism can be set as a pusher plate. The pusher plate slides and drives the pressing heads 2 to move a certain distance, so that the pressing heads 2 can face a preset direction to achieve lateral positioning. The first suction cup mechanism is used to pick up the pressing heads 2. The second conveying mechanism 320 drives the first suction cup mechanism to descend and pick up the pressing heads 2. Then, the second conveying mechanism 320 drives the first suction cup mechanism and the pressing heads 2 to move above the pump body 1. The second conveying mechanism 320 descends and presses the pressing heads 2 onto the upper end of the pump body 1.

[0031] The pump testing station 400 is equipped with a fifth cylinder, a sixth cylinder, and a second negative pressure detection device. The fifth cylinder drives the second negative pressure detection device, which is connected to the lower end of the pump body 1, forming a sealed environment. Simultaneously, the sixth cylinder presses the pressure head 2, simulating a pressing action in a usage scenario, causing a pressure change inside the pump body 1. The second negative pressure detection device detects the pressure value. For example, the second negative pressure detection device includes a pressure gauge, which monitors the pressure change in real time and records the pressure value. If the value reaches a preset standard, it indicates that the pump output of the pump body 1 meets the pumping performance requirements (i.e., it can normally extract liquid); otherwise, it is judged as unqualified.

[0032] Reference Figure 5 The locking station 500 is equipped with a seventh cylinder 510, a base 560, an eighth cylinder 570, and a locking mechanism. The seventh cylinder 510 drives the base 560 to rise, and the base 560 is locked to the lower end of the pump body 1 to fix the pump body 1 and provide a stable reference for locking. The eighth cylinder 570 drives the locking mechanism to rise and fall via a connecting rod 530. The locking mechanism includes a first servo motor 520, a pressure column 540, and a rotating pin 550. The rotating pin 550 is located on the outer periphery of the pressure column 540, and the height of the lower end face of the rotating pin 550 is lower than the height of the lower end face of the pressure column 540. The first servo motor 520 drives the rotating pin 550 to rotate around the axis of the pressure column 540. The eighth cylinder 570 drives the locking mechanism to fall, and the first servo motor 520 starts to rotate. A spring is installed at the connecting rod 530 as a cylinder buffer. When the pressure column 540 contacts the pressure head 2, the rotating pin 550 abuts against the liquid outlet end of the pressure head 2, thereby driving the pressure head 2 to rotate and locking the pressure head 2 relative to the pump body 1. After locking, the first servo motor 520 reverses 20 degrees, and all cylinders reset to avoid interference during the reset process.

[0033] Understandably, existing pump head locking machines mostly use friction or magnetic coupling to adjust the locking force during the locking process. However, due to dimensional tolerances in the pump head components during production, the required locking force is not a fixed value. These methods can result in locking that is either too loose or too tight, compromising locking quality. The locking machine in this embodiment uses a servo motor to control the locking force, precisely controlling the rotation angle and output torque to accommodate the dimensional tolerances of the pump body 1 and the pressure head 2, preventing excessive looseness or tightness and ensuring locking quality.

[0034] Reference Figure 6The sheathing station 600 is equipped with a third vibratory feeder 670, a third positioning mechanism, a tenth cylinder 650, and a second mechanical clamp 660. The third positioning mechanism is used to rotate the pressure head 2 to a preset direction to ensure the directional consistency of the sheath 3 during assembly, providing a benchmark for precise assembly. The third vibratory feeder 670 supplies the sheath 3, organizing the disordered sheath 3 into an orderly queue through vibration and conveying it to the station. The second mechanical clamp 660 clamps the sheath 3 so that the side of the sheath 3 with an opening faces the pressure head 2. The tenth cylinder 650 pushes the second mechanical clamp 660 to move, allowing the sheath 3 to complete the assembly with the pressure head 2. The direction of the pressure head 2 is adjusted by the third positioning mechanism to ensure that the assembly posture of each pressure head 2 is uniform. The tenth cylinder 650 pushes the mechanical clamp to precisely align the sheath 3 with the pressure head 2, completing the assembly. The purpose of this process is to achieve efficient integration of the sheath 3 and the pressure head 2 through automated positioning, feeding, and assembly, ultimately giving the pump head an anti-accidental contact function (limiting the downward movement of the pressure head 2) while maintaining product consistency.

[0035] Reference Figure 6 (To facilitate the display of the mating relationship, components such as pump body 1 are hidden in the diagram.) The third positioning mechanism includes a ninth cylinder 610 and a positioning component. The ninth cylinder 610 drives the positioning component to rise and fall, achieving precise docking (closer or farther away from the pressure head 2) between the positioning component and the pressure head 2. The positioning component includes a second servo motor 620, a second suction cup mechanism 630, and a positioning pin 640. The second suction cup mechanism 630 adheres tightly to the pressure head 2 through suction, providing a certain fixing force while allowing the pressure head 2 to slip relative to it (avoiding damage from hard contact). The second servo motor 620 drives the second suction cup mechanism 630 to rotate, and the positioning pin 640 is fixed, serving as a fixed limiting reference. Through contact with the liquid outlet end of the pressure head 2, it limits the rotation angle of the pressure head 2. The ninth cylinder 610 drives the positioning component to descend, causing the second suction cup mechanism 630 to adhere tightly to the pressure head 2 and adhere and fix it. The second servo motor 620 starts, driving the second suction cup mechanism 630 to rotate, thereby driving the pressure head 2 and pump body 1 to rotate synchronously through suction force. When the liquid outlet end of the pressure head 2 contacts the positioning pin 640, the pressure head 2 stops rotating due to obstruction. At this time, the second suction cup mechanism 630 continues to rotate, and the pressure head 2 slips relative to the suction cup (to avoid damage from excessive force). The servo motor reverses the preset angle, driving the pressure head 2 to rotate in the opposite direction to complete the positioning (ensuring that the liquid outlet end faces the assembly requirements of the sheath 3), and after the ninth cylinder 610 resets, interference can be avoided.

[0036] The discharge station 700, for assembled and inspected pump bodies 1, uses mechanical clamps to hold the finished product and, with the help of cylinder-driven lifting and forward / backward movement, removes the assembled and qualified sheath 3 pump head from the mold base 910 and transports it to the next process (such as packaging or boxing). The defective product station 800 is specifically used to remove unqualified semi-finished products or pump parts (such as missing glass bulbs, substandard pump performance, etc.). The discharge station 700 and the defective product station 800 form a closed loop of "qualified output - defective product removal", which not only ensures the quality of products flowing into subsequent processes, but also prevents defective products from occupying the mold base 910 or interfering with other stations by timely removal.

[0037] To better understand the locking machine of this utility model embodiment, the operation process of the locking machine of this utility model will be described below.

[0038] Pump body 1, pressure head 2, sheath 3, etc., are arranged into an orderly queue by different vibratory feeders and conveyed to the corresponding workstations using direct vibration. Under the rotation of the turntable mechanism 900, the mold base 910 moves orderly and precisely between each workstation. When the mold base 910 moves to the pump body workstation 100, the pump body 1 is clamped, removed, and placed inside the mold base 910. When the mold base 910 moves to the glass ball detection workstation 200, the airtightness inside the pump body 1 is checked to determine the presence of the glass ball. When the mold base 910 moves to the pressure head workstation 300, a suction cup is used to pick up the pressure head. Head 2 is removed and placed on pump body 1 in mold base 910; when mold base 910 moves to pump detection station 400, the pump output of pump body 1 is detected by pressing the pump head; when mold base 910 moves to locking station 500, pump body 1 is fixed and pressure head 2 is locked; when mold base 910 moves to sheath station 600, pressure head 2 is positioned, clamps sheath 3, and pushes it for assembly; when mold base 910 moves to discharge station 700, finished product is removed; when mold base 910 moves to defective product station 800, semi-finished product is removed and cleaned, and assembly is completed.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
