Description

Technical Field

[0001] This application relates to the field of glue filling technology, and in particular to a glue filling mechanism for precise quantitative dispensing. Background Technology

[0002] In modern industrial production, adhesives, as important bonding materials, are widely used in electronics, medical devices, automobile manufacturing, packaging, and many other fields. Adhesive filling is a crucial step in the production process, and its accuracy and efficiency directly affect product quality and enterprise production efficiency. A patent document with authorization announcement number CN215249511U discloses a precise quantitative adhesive filling and propulsion mechanism, including a support frame, a glue-filling tank below the support frame, a glue-filling mechanism on the outside of the glue-filling tank, a glue-receiving tank below the glue-filling tank, and a glue-receiving mechanism on the outside of the glue-receiving tank. A driving component is provided between the glue-filling mechanism and the glue-receiving mechanism.

[0003] While the above-mentioned solutions can meet the basic requirements for quantitative filling of adhesive, at least the following shortcomings have been found in actual use: only a quantitative amount of adhesive can be filled into one container at a time, resulting in low work efficiency.

[0004] Therefore, we propose a precise quantitative glue filling mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a precise quantitative glue filling mechanism that can simultaneously and accurately fill multiple glue containers, saving working time, improving work efficiency, and meeting different quantitative filling needs, thus expanding its application range.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a precise quantitative glue filling mechanism, comprising a machine base, wherein vertical plates are fixedly installed on both sides of the top of the machine base, and a horizontal plate is fixedly installed on the top of the two vertical plates. A glue quantitative filling assembly is provided between the horizontal plate and the two vertical plates. The glue quantitative filling assembly includes two connecting plates, a disc, multiple suction cylinders, multiple suction tubes, multiple filling tubes, multiple pistons, multiple transverse push-pull rods, a hydraulic cylinder, a lifting plate, and multiple connecting rods. The two connecting plates are respectively fixedly installed on the side of the two vertical plates that are close to each other. The disc is fixedly installed between the two connecting plates. The multiple suction cylinders are all fixedly installed on the top of the disc and are evenly spaced. The device is arranged in a ring. Multiple suction pipes are fixedly connected to one side of the corresponding suction cylinder, and multiple filling pipes are fixedly connected to the bottom of the corresponding suction cylinder. The bottom ends of the multiple filling pipes all pass through the first disc. Multiple pistons are slidably installed inside the corresponding suction cylinders. Multiple transverse push-pull rods are fixedly installed on one side of the corresponding pistons. One end of the multiple transverse push-pull rods extends to the outside of the corresponding suction cylinder. A hydraulic cylinder is fixedly installed at the bottom of the horizontal plate. A lifting plate is fixedly installed at the output shaft end of the hydraulic cylinder. One end of multiple connecting rods is rotatably connected to the outer wall of the lifting plate. The multiple connecting rods are evenly spaced in a ring and are inclined. The other end of the multiple connecting rods is rotatably connected to one end of the corresponding transverse push-pull rod.

[0007] By adopting the above technical solution, the vertical lifting plate can be controlled by a hydraulic cylinder. By using multiple connecting rods, the vertical movement of the lifting plate can be converted into the horizontal reciprocating movement of multiple horizontal push-pull rods and multiple pistons. By using the horizontal sliding of the pistons in the suction cylinder, the suction cylinder can suck in and discharge glue, thereby enabling the simultaneous quantitative filling of multiple glue containers, saving working time and improving work efficiency.

[0008] A further feature of this application is that: an avoidance hole is provided on the side of the suction cylinder away from the suction pipe, one end of the transverse push-pull rod passes through the avoidance hole, and the outer circular wall of the piston slides and seals against the inner wall of the suction cylinder.

[0009] By adopting the above technical solution, it is ensured that the lateral push-pull rod drives the piston to move smoothly horizontally.

[0010] A further feature of this application is that: a hinge groove 1 is provided at one end of the transverse push-pull rod outside the draw tube, and a hinge groove 2 is provided on the outer side wall of the lifting plate. A hinge shaft is fixedly installed in both hinge groove 1 and hinge groove 2, and the two ends of the connecting rod are respectively rotatably sleeved on the corresponding hinge shaft.

[0011] By adopting the above technical solution, it is possible to ensure that the vertical movement of the lifting plate is smoothly converted into the horizontal reciprocating motion of the horizontal push rod and piston.

[0012] A further provision of this application is that the glue metering filling assembly further includes a second hydraulic cylinder and a stop block. The second hydraulic cylinder is fixedly installed at the top center of the first disc, and the stop block is fixedly installed at the output shaft end of the second hydraulic cylinder. The top of the stop block abuts against the bottom of the lifting disc.

[0013] By adopting the above technical solution, the descent height of the lifting plate can be precisely positioned using the stop block, thereby ensuring that the descent height of the lifting plate remains unchanged each time. This ensures that the sliding stroke of the control piston in the suction cylinder remains constant each time, enabling precise quantitative filling. Furthermore, the hydraulic cylinder can control the vertical lifting and lowering of the stop block. By adjusting the height of the stop block, the descent height of the lifting plate can be adjusted, thereby adjusting the sliding stroke of the piston in the suction cylinder to meet different quantitative filling requirements.

[0014] A further feature of this application is that a one-way valve is fixedly installed on the suction tube, and a one-way valve is fixedly installed on the filling tube.

[0015] By adopting the above technical solution, it is ensured that the adhesive flows unidirectionally in the suction tube and filling tube, thus guaranteeing smooth quantitative dispensing of adhesive.

[0016] A further feature of this application is that a sealing cap is fixedly fitted at the bottom end of the filling tube.

[0017] By adopting the above technical solution, it is possible to prevent glue from splashing out of the glue container during the filling process.

[0018] A further feature of this application is that the tube is made of transparent tempered glass, and scale lines are provided on the outer wall of the tube.

[0019] By adopting the above technical solution, the tube made of transparent tempered glass not only has the characteristics of high strength and durability, but also has good transparency, making it easy to observe the position of the piston inside the tube. With the help of scale lines, it is easy to adjust the piston's movement stroke according to the glue filling requirements.

[0020] A further provision of this application is that: a glue container is fixedly installed on the top of the horizontal plate, the top ends of multiple suction tubes penetrate the horizontal plate and are fixedly installed on the bottom of the glue container, and the multiple suction tubes are connected to the inside of the glue container.

[0021] By adopting the above technical solution, the glue container is used to hold glue.

[0022] A further feature of this application is that the top of the glue container is provided with a feeding hole, and a plug is threaded into the feeding hole.

[0023] By adopting the above technical solution, it is convenient to add glue to the glue container.

[0024] A further feature of this application is that a hydraulic cylinder three is fixedly installed on the top of the machine tool, and a disc two is fixedly installed on the output shaft end of the hydraulic cylinder three. The top of the disc two is provided with a plurality of glue container placement slots arranged in an equal-spaced ring. The plurality of glue container placement slots are located directly below the corresponding filling tubes, and glue containers are placed in the plurality of glue container placement slots.

[0025] By adopting the above technical solution, hydraulic cylinder three is used to control the vertical lifting and lowering of disc two, which in turn can push multiple glue containers to lift and lower vertically, so as to simultaneously fill multiple glue containers with a quantitative amount of glue.

[0026] This application includes at least one of the following beneficial technical effects:

[0027] 1. This application designs a glue quantitative filling component that, without changing the height of the stop block, ensures that the height of the hydraulic cylinder remains constant during each descent. This ensures that the sliding stroke of the control piston within the suction cylinder remains constant, enabling precise quantitative filling of multiple glue containers simultaneously, saving working time and improving work efficiency. Furthermore, by using the hydraulic cylinder 2 to control the vertical lifting and lowering of the stop block, the height of the stop block can be adjusted. By adjusting the height of the stop block, the descent height of the lifting plate can be adjusted, thereby adjusting the sliding stroke of the piston within the suction cylinder. This allows for the satisfaction of different quantitative filling requirements, increasing the applicability and improving practicality.

[0028] 2. This application utilizes a sealing cap to prevent glue from splashing out of the glue container during the filling process, which not only ensures a clean working environment but also greatly reduces glue waste. Attached Figure Description

[0036] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] See Figures 1-5This application provides a precise quantitative glue filling mechanism, including a machine base 1. Vertical plates 2 are fixedly installed on both sides of the top of the machine base 1. A horizontal plate 3 is fixedly installed on the top of the two vertical plates 2. A glue quantitative filling assembly 4 is disposed between the horizontal plate 3 and the two vertical plates 2. The glue quantitative filling assembly 4 includes two connecting plates 41, a disc 42, multiple suction cylinders 43, multiple suction pipes 44, multiple filling pipes 45, multiple pistons 46, multiple horizontal push-pull rods 47, a hydraulic cylinder 48, a lifting plate 49, and multiple connecting rods 410. The two connecting plates 41 are respectively fixedly installed on the sides of the two vertical plates 2 that are close to each other. The disc 42 is fixedly installed between the two connecting plates 41. All cylinders 43 are fixedly installed on the top of the disc 42 and are distributed in a ring at equal intervals. Multiple suction pipes 44 are fixedly connected to one side of the corresponding suction cylinder 43. Multiple filling pipes 45 are fixedly connected to the bottom of the corresponding suction cylinder 43, and the bottom ends of the multiple filling pipes 45 all penetrate the disc 42. Multiple pistons 46 are slidably installed inside the corresponding suction cylinder 43. Multiple transverse push-pull rods 47 are fixedly installed on one side of the corresponding piston 46, with one end of each transverse push-pull rod extending outside the corresponding suction cylinder 43. A hydraulic cylinder 48 is fixedly installed at the bottom of the horizontal plate 3. A lifting plate 49 is fixedly installed at the output shaft end of the hydraulic cylinder 48. One end of multiple connecting rods 410 is connected to... The outer wall of the lifting plate 49 is rotatably connected, and multiple connecting rods 410 are evenly spaced in a ring and inclined. The other end of each connecting rod 410 is rotatably connected to one end of a corresponding transverse push-pull rod 47. The vertical lifting of the lifting plate 49 can be controlled by a hydraulic cylinder 48. The vertical movement of the lifting plate 49 can be converted into the horizontal reciprocating movement of multiple transverse push-pull rods 47 and multiple pistons 46 by the multiple connecting rods 410. The horizontal sliding of the pistons 46 in the suction cylinder 43 enables the suction cylinder 43 to draw in and discharge glue. The glue metering filling assembly 4 also includes a hydraulic cylinder 411 and a stop block 412. The hydraulic cylinder 411 is fixedly installed at the top center of the disc 42. The stop block 412 is fixedly installed at the output shaft end of the hydraulic cylinder 411. The top of the stop block 412 abuts against the bottom of the lifting plate 49. The stop block 412 can be used to accurately position the descent height of the lifting plate 49, thereby ensuring that the descent height of the lifting plate 49 remains unchanged each time. This ensures that the sliding stroke of the control piston 46 in the suction cylinder 43 remains unchanged each time, enabling precise quantitative filling. Moreover, the hydraulic cylinder 411 can control the vertical lifting and lowering of the stop block 412. By adjusting the height of the stop block 412, the descent height of the lifting plate 49 can be adjusted, thereby adjusting the sliding stroke of the piston 46 in the suction cylinder 43 to meet different quantitative filling requirements.

[0038] In this embodiment, a clearance hole is provided on the side of the suction cylinder 43 away from the suction pipe 44, and one end of the transverse push-pull rod 47 passes through the clearance hole. The outer circular wall of the piston 46 slides and seals against the inner wall of the suction cylinder 43 to ensure that the transverse push-pull rod 47 drives the piston 46 to move horizontally smoothly.

[0039] In this embodiment, the transverse push-pull rod 47 has a hinge groove 1 at one end outside the draw cylinder 43, and the outer side wall of the lifting plate 49 has a hinge groove 2. A hinge shaft is fixedly installed in both the hinge groove 1 and the hinge groove 2. The two ends of the connecting rod 410 are respectively rotatably sleeved on the corresponding hinge shaft, which can ensure that the vertical movement of the lifting plate 49 is smoothly converted into the horizontal reciprocating movement of the transverse push-pull rod 47 and the piston 46.

[0040] In this embodiment, a one-way valve 413 is fixedly installed on the suction pipe 44, and a one-way valve 414 is fixedly installed on the filling pipe 45 to ensure that the adhesive flows in one direction in the suction pipe 44 and the filling pipe 45, and that backflow will not occur, thus ensuring that the quantitative delivery of adhesive is smooth.

[0041] In this embodiment, a sealing cap 415 is fixedly sleeved at the bottom end of the filling tube 45. The design of the sealing cap 415 prevents glue from splashing out of the glue container 10 during the filling process, which can not only ensure a clean working environment, but also greatly reduce glue waste.

[0042] In this embodiment, the tube 43 is made of transparent tempered glass. The outer wall of the tube 43 is provided with scale lines 416. The tube 43 made of transparent tempered glass not only has the characteristics of high strength and durability, but also has good transparency, which makes it easy to observe the position of the piston 46 inside the tube 43. With the scale lines 416, it is convenient to adjust the movement stroke of the piston 46 according to the glue filling requirements.

[0043] In this embodiment, a glue container 5 is fixedly installed on the top of the horizontal plate 3. The top ends of multiple suction pipes 44 all penetrate the horizontal plate 3 and are fixedly installed on the bottom of the glue container 5. The multiple suction pipes 44 are all connected to the inside of the glue container 5. The glue container 5 is used to hold glue. A feeding hole is opened on the top of the glue container 5. A plug 6 is threaded in the feeding hole to facilitate adding glue to the glue container 5.

[0044] In this embodiment, a hydraulic cylinder 3 7 is fixedly installed on the top of the machine base 1, and a disc 2 8 is fixedly installed on the output shaft end of the hydraulic cylinder 3 7. The top of the disc 2 8 is provided with multiple glue container placement slots 9 arranged in an evenly spaced ring. The multiple glue container placement slots 9 are located directly below the corresponding filling tubes 45. Each of the multiple glue container placement slots 9 contains a glue container bottle 10. The hydraulic cylinder 3 7 can control the vertical lifting and lowering of the disc 2 8, thereby pushing the multiple glue container bottles 10 to lift and lower vertically, so as to simultaneously fill the multiple glue container bottles 10 with glue in a quantitative manner. This enables the simultaneous quantitative filling of multiple glue container bottles 10, saving working time and improving work efficiency.

[0045] In this embodiment, it should be noted that hydraulic cylinder 48, hydraulic cylinder 411, and hydraulic cylinder 7 are all commercially available, and their wiring connection and control methods are mature technologies in the field and have been fully disclosed, so they will not be described in detail here.

[0046] With the above structure, the working principle of the precise quantitative glue filling mechanism provided in this application is as follows:

[0047] Unscrew the stopcock 6 and pour glue into the glue container 5 through the feeding hole. Then tighten the stopcock 6 in the feeding hole. Next, take multiple glue containers 10 and place them into the corresponding glue container placement slots 9. Then control the hydraulic cylinder 3 7 to extend and run, which will push the disc 2 8 and multiple glue containers 10 to rise vertically until the tops of multiple glue containers 10 touch the corresponding sealing caps 415. Stop the operation of the hydraulic cylinder 3 7. At this time, the bottom ends of multiple filling tubes 45 are also inserted into the corresponding glue containers 10.

[0048] Next, the hydraulic cylinder 48 retracts and resets once, causing the lifting plate 49 to rise. At this time, multiple connecting rods 410 pull the corresponding transverse push rods 47 outward from the suction cylinder 43. The multiple transverse push rods 47 move the corresponding pistons 46, creating negative pressure inside the multiple suction cylinders 43. The glue in the glue container 5 is sucked into each suction cylinder 43 through multiple suction pipes 44. Then, the hydraulic cylinder 48 extends once, causing the lifting plate 49 to descend. At this time, multiple connecting rods 410 push the corresponding transverse push rods 47 inward from the suction cylinder 43. The multiple transverse push rods 47 move the corresponding pistons 46, increasing the pressure inside the multiple suction cylinders 43. The glue in multiple suction cylinders 43 is discharged through the corresponding filling tubes 45 and filled into the corresponding glue containers 10. When the lifting plate 49 descends to the stop block 412, the operation of the hydraulic cylinder 48 is stopped, thus completing the simultaneous quantitative filling of glue into these glue containers 10. Then, the hydraulic cylinder 7 is controlled to retract and reset, and the glue container placement slot 9 and multiple glue containers 10 filled with glue are controlled to descend vertically back to their original positions. The multiple glue containers 10 filled with glue can then be taken out in sequence for subsequent sealing and packaging. By following the above operation steps, multiple glue containers 10 can be taken out again and placed into the corresponding glue container placement slot 9 in sequence to continue the simultaneous quantitative filling of multiple glue containers 10.

[0049] During the batch filling process of glue containers 10 of the same size, without changing the height position of the stop block 412, the height position of the hydraulic cylinder 48 can be kept constant each time it descends, so that the sliding stroke of the control piston 46 in the pump cylinder 43 remains constant each time, thus achieving precise quantitative filling.

[0050] When batch filling glue containers 10 of other sizes, the height of the stop block 412 can be adjusted by controlling the vertical lifting of the stop block 412 using the hydraulic cylinder 411. By adjusting the height of the stop block 412, the descent height of the lifting plate 49 can be adjusted, thereby adjusting the sliding stroke of the piston 46 in the suction cylinder 43. This can meet the quantitative filling volume requirements of different needs, increase the scope of application, and improve the practical performance.
