Description

Technical Field

[0001] The invention relates to the field of automated assembly production, and in particular to self-adaptive jacking type pump head assembly equipment and an assembly method. Background Art

[0002] The press-type lotion pump is the most common type. Users release liquid by pressing the pump head. It is suitable for the packaging of a variety of liquid products. Users can press the pump head to obtain lotion according to actual needs. It is convenient for people to use, saves raw materials, does not cause waste, and can ensure the cleanliness of the lotion in the container. Therefore, it is widely used in household, medical, industrial and other occasions.

[0003] In the automated production of pump heads, turntable-type automated equipment is usually used to realize automatic loading, assembly and unloading processes. For this purpose, multiple points are set along the circumference of the turntable. Whenever the pump head is assembled and driven to the unloading position by the rotation of the turntable, the assembled pump head is transferred and collected by a robot, or some production lines use a jacking method to eject the pump head. In order to ensure that the pump head can produce a horizontal displacement difference after being ejected, so that the pump head can smoothly fall to the side of the equipment, a unloading chute is usually set at the unloading position, and the upper end of the unloading chute is provided with an inclined portion as a guide. After the pump body is ejected, it collides with the inclined portion. Under the interference of the inclined portion, the pump head can be offset in the horizontal direction and unload smoothly.

[0004] When the above-mentioned lifting discharge method is implemented, the lifting part uses inertia to push the pump head out. For this, the pump head needs to be subjected to a large thrust force to ensure effective discharge. As a result, the pump head and the inclined part will have a large collision, which may cause defects on the surface of the pump head. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0035] See also Figure 1-Figure 10In an embodiment of the present invention, an adaptive jacking pump head assembly device includes a base 1 and a turntable 2 arranged on the base 1, and the turntable 2 can intermittently rotate on the base 1; the adaptive jacking pump head assembly device also includes: a cylinder 8, a plurality of groups of which are equidistantly arranged along the circumference of the turntable 2, each group of the cylinders 8 includes two, connected to the mounting structure arranged on the turntable 2, and each group of the cylinders 8 is connected to a group of deflection drive mechanisms installed on the turntable 2, and the deflection drive mechanism can drive the cylinder 8 to perform a deflection action , so that the cylinder 8 switches from a vertical state to an inclined state; a material ejection mechanism is arranged in the cylinder 8, and the material ejection mechanism is connected to an ejection mechanism, and the ejection mechanism is triggered after the deflection movement of the cylinder 8 ends, and can cause the material ejection mechanism to move along the axial direction of the cylinder 8 to push out the pump head located in the cylinder 8 in an inclined state; a lifting mechanism is installed on the base 1, and can be lifted and lowered above the turntable 2, and is used to transfer the assembly parts to the cylinder 8 to complete the assembly, and the lifting mechanism cooperates with the deflection drive mechanism. The lifting mechanism includes a hydraulic cylinder 3 installed on the base 1, and the movable end of the hydraulic cylinder 3 passes through the turntable 2 and is fixedly installed with a lifting platform 4, and a column 20 is also fixedly provided at the bottom of the lifting platform 4. When the hydraulic cylinder 3 drives the lifting platform 4 to drive the column 20 to descend, the column 20 can cooperate with the deflection drive mechanism to cause the cylinder 8 located at the lowering position to perform a deflection movement.

[0036] Furthermore, the pump head includes a pump body, a button, an outlet, a container interface, a sealing ring and other parts. For this, it is necessary to form a complete automatic assembly production line for the pump head together with other devices. During assembly, these parts need to be transferred to the cylinder 8 in sequence to complete the assembly. For this, in the specific implementation, corresponding parts transportation devices (such as vibration plate automatic loader, etc.) are also arranged around the turntable 2, and a negative pressure suction mechanism is provided on the lifting platform 4. These devices cooperate with the lifting and lowering of the lifting platform 4, so that the components of the pump head are transferred to the cylinder 8 one by one, and finally assembled in the cylinder 8. The above all adopt mature existing technologies. The specific operation process and the distance therein are no longer repeated in this application. The purpose of this application is that whenever the turntable 2 stops rotating, that is, when the lifting platform 4 is lifted, the cylinder 8 located at the lowering position can be driven to deflect through the deflection drive mechanism, and the ejection mechanism is triggered, and the assembled pump head is ejected from the cylinder 8 by the ejection mechanism.

[0037] Please refer again Figure 5 , Figure 6 as well as Figure 8The mounting structure includes two vertical plates 6 fixed on the turntable 2 and arranged opposite to each other, and two rotating shafts 7 rotatably mounted on the two vertical plates 6, respectively. The two cylinders 8 are respectively fixed to the two rotating shafts 7. The two cylinders 8 are fixed by a shaft 9, which is concentric with the two rotating shafts 7. The shaft 9 is connected to the deflection drive mechanism, and the rotating shaft 7 is connected to the ejection mechanism.

[0038] Please refer again Figure 7 , Figure 8 as well as Fig.10 The deflection drive mechanism includes an elastic sliding assembly mounted on the turntable 2 and a sliding matching structure connecting the elastic sliding assembly and the shaft 9, and the elastic sliding assembly matches the column 20. The elastic sliding assembly includes two guide columns 14 fixed on the turntable 2, two sleeves 15 respectively slidably mounted on the two guide columns 14, and two third cylindrical springs 23 respectively mounted on the outer peripheries of the two guide columns 14; wherein the two ends of the third cylindrical spring 23 are respectively connected to the sleeve 15 and the turntable 2, and a follower plate 16 is fixedly connected between the two sleeves 15, and a lug 19 matching the column 20 is fixedly provided on the side of the follower plate 16.

[0039] Whenever the turntable 2 completes its rotation, the lug 19 at the unloading position corresponds to the column 20, and then the hydraulic cylinder 3 drives the lifting platform 4 to drive the column 20 to descend. The column 20 will contact the lug 19 and apply a downward thrust to the lug 19, and then the lug 19 drives the sleeve 15 to slide downward on the guide column 14. At this time, the third column spring 23 is compressed, and the follower plate 16 causes the sliding fit structure to be triggered, and the sliding fit structure drives the shaft 9 to rotate, so that the cylinder 8 swings toward the outside of the turntable 2, and the cylinder 8 switches from a vertical state to an inclined state. Then the ejection mechanism causes the ejection mechanism to move along the axial direction of the cylinder 8 to eject the assembled pump head in the cylinder 8, thereby realizing the automatic unloading function.

[0040] The sliding matching structure includes a driven shaft 11 rotatably mounted on the turntable 2 and a follower tube 17 slidably sleeved on the driven shaft 11, the follower tube 17 is fixed to the follower plate 16, and the end of the driven shaft 11 away from the turntable 2 is connected to the shaft member 9 through the bevel gear set 10. A driving column 18 is fixed to the follower tube 17, and a sliding groove 1101 adapted to the driving column 18 is provided on the outer wall of the driven shaft 11, the sliding groove 1101 is spirally arranged, and the driving column 18 extends into the sliding groove 1101 and is slidably connected to the driven shaft 11.

[0041] The bevel gear set 10 includes a first bevel gear fixedly mounted on an end of the driven shaft 11 away from the turntable 2 and a second bevel gear fixed on the shaft 9 , wherein the second bevel gear meshes with the first bevel gear.

[0042] Specifically, when the lug 19 is pushed downward by the column 20 and drives the follower plate 16 to move downward, the follower plate 16 drives the follower tube 17 to slide downward on the driven shaft 11, and then the driving column 18 moves linearly along the axial direction of the driven shaft 11, and slides with the driven shaft 11 through the slide groove 1101, so that the driven shaft 11 rotates, and the driven shaft 11 drives the shaft member 9 to rotate through the bevel gear set 10, so that the two cylinders 8 are tilted. It is convenient to extract the pump head in the cylinder 8; when the lifting platform 4 rises, the third column spring 23 rebounds, and the sleeve 15 slides upward on the guide column 14 to reset, and accordingly, the follower plate 16 drives the follower tube 17 to slide upward on the driven shaft 11 to reset, and the driving column 18 slides with the driven shaft 11 again through the slide groove 1101, so that the cylinder 8 is deflected from the inclined state to the initial vertical state. With the rotation of the turntable 2, the unloaded cylinder 8 is assembled with the pump head components.

[0043] Please refer again Fig. 9 The ejection mechanism includes a piston 12 disposed in the cylinder 8 and a push rod 13 slidably disposed on the cylinder 8 and fixedly connected to the piston 12. One end of the push rod 13 away from the piston 12 extends to the outside of the cylinder 8 and is connected to the ejection mechanism.

[0044] Furthermore, a countersunk hole is provided on the bottom wall of the cylinder 8, and the countersunk hole is adapted to the piston 12 and the push rod 13. When the cylinder 8 is in a vertical state, the piston 12 is located in the countersunk hole to ensure the flatness of the bottom wall of the cylinder 8.

[0045] The ejection mechanism includes a swing plate 27 fixed to the end of the rotating shaft 7 away from the cylinder 8, a slider 28 slidably arranged on the swing plate 27, and a two-way telescopic assembly arranged on the slider 28. The two-way telescopic assembly includes an assembly cylinder 24 fixed to the slider 28 and connected at both ends, a telescopic rod 25 slidably fitted with the assembly cylinder 24, and a first cylindrical spring 21 and a second cylindrical spring 22 arranged inside the assembly cylinder 24. One end of the telescopic rod 25 is fixed to the end of the push rod 13 away from the piston 12 through a connecting arm 26, and the other end is connected to a limit assembly arranged on the vertical plate 6. The telescopic rod 25 is also fixedly connected to a truncated cone 5 arranged in the assembly cylinder 24. The first cylindrical spring 21 and the second cylindrical spring 22 have their head ends connected to the truncated cone 5, and their tail ends abut against the inner wall of the assembly cylinder 24. The limiting assembly includes an arc-shaped plate 29 fixed to the vertical plate 6 by two fixing arms 30, the arc-shaped plate 29 is concentric with the rotating shaft 7, and a fan-shaped groove and an inclined groove 2905 are provided on the arc-shaped plate 29, and a boss 2401 is also fixed to the outer wall of the assembly tube 24, the boss 2401 extends into the inclined groove 2905 and is slidably connected to the arc-shaped plate 29; the end of the telescopic rod 25 away from the connecting arm 26 extends into the fan-shaped groove and is slidably connected to the arc-shaped plate 29.

[0046] Further, the fan-shaped groove includes a first groove 2901, a second groove 2902, a third groove 2903 and a fourth groove 2904 which are connected to each other, wherein the first groove 2901 and the third groove 2903 are arc grooves, and the second groove 2902 and the fourth groove 2904 are distributed along the radial direction of the arc plate 29; during the switching process of the cylinder 8 from the vertical state to the inclined state, the swing plate 27 swings, and the convex column 2401 slides with the arc plate 29 through the inclined groove 2905 , causing the slider 28 to slide on the swing plate 27 toward the rotating shaft 7, at which time the end of the telescopic rod 25 away from the connecting arm 26 deflects along the first groove 2901, and the first cylindrical spring 21 is compressed. After the state switching of the cylinder 8 is completed, the end of the telescopic rod 25 away from the connecting arm 26 reaches the connection between the first groove 2901 and the second groove 2902, and the first cylindrical spring 21 rebounds. The telescopic rod 25 will lift the push rod 13 through the connecting arm 26, and the push rod 13 3 pushes the piston 12 to slide in the cylinder 8 toward the outside of the cylinder 8, so that the pump head in the cylinder 8 is discharged, realizing the automatic discharge function. Accordingly, the end of the telescopic rod 25 away from the connecting arm 26 is transferred from the connection between the first groove 2901 and the second groove 2902 to the connection between the second groove 2902 and the third groove 2903; in the process of the cylinder 8 switching from the inclined state to the vertical state, the boss 2401 is slidably matched with the arc plate 29 again, and the slider 28 is The swing plate 27 slides away from the rotating shaft 7. At this time, the end of the telescopic rod 25 away from the connecting arm 26 deflects along the third groove 2903, and the second cylindrical spring 22 is compressed. After the cylinder 8 recovers to the vertical state, the end of the telescopic rod 25 away from the connecting arm 26 reaches the connection between the third groove 2903 and the fourth groove 2904, and the second cylindrical spring 22 rebounds. The telescopic rod 25 pulls the piston 12 to return to the bottom wall of the cylinder 8 through the connecting arm 26 and the push rod 13.

[0047] It should be emphasized that, compared with the first cylindrical spring 21 and the second cylindrical spring 22 , the third cylindrical spring 23 has a larger elastic potential energy, thereby ensuring the stability of the cylinder 8 when it is in a vertical state.

[0048] As another embodiment of the present invention, a pump head assembly method is also proposed, using the pump head assembly device, comprising the following steps:

[0049] Step 1: The rotation of the turntable 2 and the action of the lifting mechanism are performed alternately;

[0050] Step 2: The lifting mechanism transfers the pump head components one by one into the cylinder 8 and completes the assembly;

[0051] Step 3: The turntable 2 drives the cylinder 8 to rotate to the unloading position, and the deflection drive mechanism is triggered to drive the cylinder 8 to deflect from the vertical state to the inclined state;

[0052] Step 4: the cylinder 8 stops deflecting, and the ejection mechanism is triggered, prompting the ejection mechanism to move along the axial direction of the cylinder 8, leading the pump head in the cylinder 8 out, and completing the discharge.
