Description

Technical Field

[0001] This invention belongs to the field of dispensing technology, and in particular relates to a dispensing device and a dispensing method thereof. Background Technology

[0002] Dispensing is widely used in industries such as manufacturing and decoration. Currently, dispensing equipment differs significantly between precision machining and general machining. In general machining, where precision requirements are not high and dispensing machines are expensive, manual dispensing is still used. However, in precision machining, where high precision is required for dispensing, CNC machine tools are used in conjunction with dispensing equipment. In processes requiring both precision and mass production, there is a lack of equipment that can simultaneously meet both requirements. Therefore, this paper proposes a dispensing device and its dispensing method. Summary of the Invention

[0003] The purpose of this invention is to provide a dispensing device and a dispensing method thereof to solve existing problems.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a dispensing device, comprising a dispensing head, a glue pump, an adjusting mechanism, and a clamp. One end of the dispensing head is connected to a dispensing tube, which is a two-inlet, one-outlet pipe. The two inlets of the dispensing tube are connected to the outlet of the glue pump. The inlet of the glue pump is connected to an inlet pipe. The glue pump is connected to the adjusting mechanism, which is connected to the clamp. Glue flows from the inlet pipe into the glue pump, then from the glue pump into the dispensing tube, and finally exits from the dispensing head through the converging point of the dispensing tube. The dispensing head controls the single dispensing flow rate and provides power to the glue pump. The adjusting mechanism adjusts the dispensing frequency. The clamp works in conjunction with the adjusting mechanism to provide driving force for the adjusting mechanism to operate the glue pump.

[0006] Preferably, the adhesive pump includes a pump tube, a pump chamber, a sealing ball, a pump rod, pump blades, a fixing frame, a drive sleeve, and a reset spring; two pump chambers are arranged opposite each other at both ends of the pump rod, and both ends of the pump rod are inserted into the pump chambers; two pump blades are respectively installed at both ends of the pump rod, and the two pump blades are respectively arranged in the two pump chambers; two pump tubes are respectively arranged on the outer peripheral surface of the pump chamber, and a sealing chamber is arranged at the end of the pump tube away from the pump chamber, and the sealing ball is installed in the sealing chamber, and the sealing ball and the sealing chamber are movably fitted; a fixing frame is arranged on the opposite side of the two pump chambers, and the fixing frame is nested at both ends of the pump rod and fixed. The frame and pump rod slide together; a drive sleeve is nested in the middle of the pump rod, and a reset spring is provided on one end face of the drive sleeve; the pump impeller and the pump chamber are connected by a sealing rubber ring; the adhesive enters the pump chamber through one pump pipe, and then flows out through another pump pipe by the pump impeller in the pump chamber. The two sealing chambers, two pump pipes, and one pump chamber form a power mechanism. When the pump impeller contracts, the pump chamber creates a negative pressure on the pump pipes on both sides, and the flow of the adhesive drives the sealing ball inside to move to one side of the pump chamber. Since the contraction and expansion directions of the two sealing chambers are the same, the sealing ball on the side closer to the adhesive inlet pipe is at its position. On the expanded side of the sealed chamber, the sealing ball near the outlet pipe is on the contracted side of its respective sealed chamber. That is, the inlet pipe is open, and the outlet pipe is closed. When the pump impeller continues to contract, the resulting negative pressure draws the adhesive into the pump chamber. When the pump impeller expands, the adhesive in the pump chamber is under high pressure, and the adhesive pushes the sealing balls on both sides away from the pump chamber. Following the same principle, at this time, the sealing ball near the inlet pipe and its corresponding sealed chamber are closed, while the sealing ball near the outlet pipe and its corresponding sealed chamber are open, and the adhesive is discharged into the chamber. The adhesive is fed into the dispensing tube and then squeezed into the dispensing head. By setting up two stacked pump chambers, it is possible to achieve the following: when one pump chamber is squeezing the adhesive, the other pump chamber is drawing in the adhesive. And because there is always one sealed chamber near the dispensing tube, it can prevent the adhesive in one pump chamber from flowing back into the other pump chamber, thereby improving the pumping efficiency. The fixed frame is used to limit the pump rod. The drive sleeve cooperates with the moving plate to drive the pump rod to move to one side. The reset spring is used to store the potential energy stored during compression and cooperates with the moving plate to form a reverse thrust on the pump rod, thereby making the pump rod reciprocate.

[0007] Preferably, the adjustment mechanism includes a slide rod, a movable plate, a drive arm, a transmission disk, a proportional mechanism, an adjustment disk, a rocker arm, and a drive disk; several slide rods are fixed between two pump chambers, the movable plate is nested on the slide rods, and the movable plate and the slide rods are slidably engaged; one end of the movable plate is sleeved on the pump rod and is disposed between the drive sleeve and the fixed frame on the side away from the reset spring, and the other end of the movable plate is rotatably connected to the drive arm; both ends of the drive arm are rotatably connected to the movable plate and the transmission disk, respectively; the transmission disk is connected to the proportional mechanism; the proportional mechanism meshes with the adjustment disk, and a rocker arm is inserted into the shaft of the adjustment disk; the proportional mechanism meshes with the drive disk; the movable plate slides on the slide rod, the transmission disk drives the movable plate to move through the drive arm, and the adjustment disk adjusts the rotation ratio between the drive disk and the transmission disk through the proportional mechanism; the rocker arm is a force-saving mechanism for driving the adjustment disk.

[0008] Preferably, the proportional mechanism includes an output disc, an input disc, a steel strip, a fixed rod, a threaded rod, and a threaded disc. The output disc and the input disc have the same structure, each including a fixed disc and a movable disc, which are arranged opposite to each other. The fixed disc has the same structure as the movable disc, and the fixed disc is a spliced ​​structure of a disc and a frustum, with teeth provided on the inclined surface of the frustum. The movable disc is coaxially and parallel to the fixed disc, and the inclined surfaces of the movable disc and the fixed disc with teeth are opposite to each other. The steel strip has a cross-section of a trapezoid and a rectangle, and teeth are also provided on the two inclined surfaces of the trapezoidal part of the steel strip. The teeth on the two inclined surfaces of the steel strip mesh with the teeth on the inclined surfaces of the movable disc and the fixed disc.

[0009] In this design, the fixed and movable discs of the output and input discs are positioned oppositely. The output disc is connected to the input disc via a steel belt. The movable discs of the output and input discs are connected by a fixed rod. The fixed rod has a threaded hole on its side, which is threaded to a threaded rod. A threaded disc is fixedly connected to the threaded rod, and the threaded disc engages with an adjusting disc. The fixed disc of the output disc engages with a transmission disc, and the fixed disc of the input disc engages with a drive disc. The fixed rod connects the movable discs of the output and input discs. The threaded disc drives the threaded rod to rotate, and the threaded rod drives the fixed rod to move horizontally through the threaded hole, thereby moving the movable discs of the output and input discs connected to the fixed rod. Because the fixed and movable discs of the output and input discs are positioned oppositely, when the distance between the movable disc and the fixed disc of the output disc increases, the distance between the movable disc and the fixed disc of the input disc decreases, and vice versa. Therefore, the transmission ratio of the input and output discs connected by the steel belt can be proportionally adjusted.

[0010] Preferably, the two clamps are arranged in parallel relative to each other; each clamp includes a fixed frame, a clamp seat, a lifting seat, and springs; both the clamp seat and the lifting seat are installed inside the fixed frame, and the clamp seat and the lifting seat are slidably engaged; one end of each of the springs is installed on the upper surface of the lifting seat, and the other end is connected to the inner surface of the fixed frame.

[0011] Wherein, the cross-section of the clamp is a right trapezoid; the cross-section of the lifting seat is a combination of a right trapezoid and a "convex" shape; the inclined waist of the right trapezoid in the cross-section of the clamp fits with the inclined waist of the right trapezoid in the cross-section of the lifting seat; the top surface of the lifting seat is provided with several teeth, and several springs are provided on one side of the teeth of the lifting seat.

[0012] The fixed frame has a slot inside; the clamp has inserts on both sides, which slide in the slot; the fixed frame has several openings on top, the position and number of which correspond to the teeth on the lifting seat installed inside the fixed frame.

[0013] The teeth on the lifting seat mesh with the drive disc;

[0014] The fixed frame is used to limit the clamp, lifting seat, and spring. The clamp is tightly clamped to the edge of the material to be glued. When the material to be glued is squeezed against the clamp, the inclined surfaces of the clamp and the lifting seat slide out of alignment. Since the lifting seat is limited by the fixed frame, it can only move upward. During the upward movement of the lifting seat, the teeth set on the lifting seat pass through the opening at the top of the fixed frame. At this time, the top surface of the clamp forms a rack structure, which, through the cooperation of the drive disc, generates the force to drive the glue pump. The spring is also compressed during this process, which facilitates the lifting seat to provide a downward thrust when it resets.

[0015] Preferably, the structure of the sealed chamber includes two parts: one part is a cylindrical cavity that gradually contracts at one end and gradually expands at the other end; the other part is a baffle with a polygonal opening located at the gradually expanding end of the cylindrical cavity; a sealing ball is installed inside the cylindrical cavity; and the two sealed chambers connected to a pump chamber have the same direction of contraction and expansion, wherein the gradually contracting end is the glue inlet and the gradually expanding end is the glue outlet.

[0016] Preferably, the dispensing equipment further includes a positioning frame, on which the dispensing head, glue pump, and adjustment mechanism are all fixed. The positioning frame is slidably engaged with the clamp. The shape of the positioning frame is adapted to the fixed position required by the components of the dispensing head, glue pump, and adjustment mechanism. The function of the positioning frame is to fix and limit the various components.

[0017] Preferably, the surface of the adjustment disc is provided with a scale to facilitate setting a suitable transmission ratio.

[0018] A dispensing method using a dispensing device includes the following steps:

[0019] Step 1: Connect the glue inlet tube of the dispensing equipment to the container storing the glue; and start the glue pump by rotating the drive disc to fill the glue inlet tube, glue pump, glue outlet tube and dispensing head with glue;

[0020] Step 2: Adjust the dispensing frequency according to the dispensing requirements. Start the adjustment dial by rotating the joystick and adjust it according to the scale on the adjustment dial.

[0021] Step 3: Clamp the material to be glued using the fixture, align the edge of the material to be glued with the clamp seat of the fixture, and use the extrusion device to fix the material and the fixture firmly.

[0022] Step 4: Move the positioning frame and apply adhesive.

[0023] The present invention has the following beneficial effects:

[0024] This invention, by setting up an adjustment mechanism that works in conjunction with the clamp of the material to be glued, enables glue dispensing to be completed without the need for additional power equipment when moving the positioning frame; the adjustment mechanism also allows for adjustment of the dispensing frequency, improving the applicability of the equipment.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0040] Please see Figure 1-2As shown, the present invention is a dispensing device, including a dispensing head 1, a glue pump 2, an adjusting mechanism 3, and a clamp 4. One end of the dispensing head 1 is connected to a glue outlet pipe 11, which is a two-inlet, one-outlet pipe. The two inlets of the glue outlet pipe 11 are connected to the outlet of the glue pump 2. The inlet of the glue pump 2 is connected to an inlet pipe 12. The glue pump 2 is connected to the adjusting mechanism 3, and the adjusting mechanism 3 is connected to the clamp 4. The glue flows from the inlet pipe 12 into the glue pump 2, and then from the glue pump 2 into the glue outlet pipe 11. The glue is then discharged from the dispensing head 1 through the convergence of the glue outlet pipe 11. The function of the dispensing head 1 is to control the single dispensing flow rate and to provide power for dispensing through the glue pump 2. The function of the adjusting mechanism 3 is to adjust the dispensing frequency. The clamp 4 cooperates with the adjusting mechanism 3 to provide driving force for the adjusting mechanism 3 to drive the glue pump 2 to work.

[0041] The glue pump 2 includes a pump pipe 21, a pump chamber 22, a sealing ball 24, a pump rod 25, pump blades 26, a fixing frame 27, a drive sleeve 28, and a reset spring 29. Two pump chambers 22 are positioned opposite each other at the ends of the pump rod 25, with both ends of the pump rod 25 inserted into the pump chambers 22. Two pump blades 26 are respectively installed at the ends of the pump rod 25 and are respectively positioned within the two pump chambers 22. Two pump pipes 21 are respectively provided on the outer peripheral surface of the pump chambers 22. A sealing chamber 23 is provided at the end of the pump pipe 21 away from the pump chamber 22, and the sealing ball 24 is installed within the sealing chamber 23, with the sealing ball 24 movably engaging with the sealing chamber 23. Fixing frames 27 are provided on the opposite surfaces of the two pump chambers 22, and the fixing frames 27 are nested within each other. At both ends of the pump rod 25, the fixing bracket 27 slides with the pump rod 25; a drive sleeve 28 is nested in the middle of the pump rod 25, and a reset spring 29 is provided on one end face of the drive sleeve 28; the pump blade 26 is connected to the pump chamber 22 by a sealing rubber ring; the adhesive enters into the pump chamber 22 through one pump pipe 21, and then flows out from the other pump pipe 21 by the pump blade 26 in the pump chamber 22. The two sealing chambers 23, the two pump pipes 21, and the pump chamber 22 form a power mechanism. When the pump blade 26 contracts, the pump chamber 22 creates a negative pressure on the pump pipes 21 on both sides. The flow of the adhesive drives the sealing ball 24 inside to move to one side of the pump chamber 22. Since the contraction and expansion directions of the two sealing chambers 23 are the same, the ball moves closer to the inlet pipe. The sealing ball 24 on one side of the inlet pipe 12 is located on the expanded side of its sealed chamber 23, while the sealing ball 24 on the side closer to the outlet pipe 11 is located on the contracted side of its sealed chamber 23. That is, the inlet pipe 12 is in the open state, and the outlet pipe 11 is in the closed state. When the pump impeller 26 continues to contract, the resulting negative pressure draws the adhesive into the pump chamber 22. When the pump impeller 26 expands, the adhesive in the pump chamber 22 is under high pressure, and the adhesive pushes the sealing balls 24 on both sides to move away from the pump chamber 22. Following the same principle, at this time, the sealing ball 24 closer to the inlet pipe 12 and its sealed chamber 23 are in a closed state, while the sealing ball 24 closer to the outlet pipe 11 and its sealed chamber 23 are in an open state. In the first stage, the adhesive is discharged into the dispensing pipe 11 and then squeezed into the dispensing head 1. By setting two stacked pump chambers 22, it is possible to achieve that when one pump chamber 22 is squeezing the adhesive, the other pump chamber 22 is sucking in the adhesive. And since there is always a closed sealing chamber 23 near the dispensing pipe 11, it can prevent the adhesive in one pump chamber 22 from flowing back into the other pump chamber 22, thereby improving the pumping efficiency. The function of the fixing frame 27 is to limit the pump rod 25. The drive sleeve 28 cooperates with the moving plate 32 to drive the pump rod 25 to move to one side. The reset spring 29 is used to store the potential energy stored during compression and cooperates with the moving plate 32 to form a reverse thrust on the pump rod 25, thereby making the pump rod 25 reciprocate.

[0042] The sealed chamber 23 has two parts: one part is a cylindrical cavity that gradually contracts at one end and gradually expands at the other end; the other part is a baffle with a polygonal opening located at the gradually expanding end of the cylindrical cavity. The sealing ball 24 is installed inside the cylindrical cavity. The two sealed chambers 23 connected to a pump chamber 22 have the same direction of contraction and expansion, with the gradually contracting end being the glue inlet and the gradually expanding end being the glue outlet.

[0043] The adjusting mechanism 3 includes a slide rod 31, a movable plate 32, a drive arm 33, a transmission disk 34, a proportional mechanism 35, an adjusting disk 36, a rocker arm 37, and a drive disk 38. Several slide rods 31 are fixed between two pump chambers 22. The movable plate 32 is nested on the slide rods 31, and the movable plate 32 slides in cooperation with the slide rods 31. One end of the movable plate 32 is sleeved on the pump rod 25 and is positioned between the drive sleeve 28 and the fixed frame 27 on the side away from the reset spring 29. The other end of the movable plate 32 is rotatably connected to the drive arm 33. The two ends of the arm 33 are rotatably connected to the moving plate 32 and the transmission disk 34, respectively; the transmission disk 34 is connected to the proportional mechanism 35; the proportional mechanism 35 is engaged with the adjusting disk 36, and a rocker arm 37 is inserted into the shaft of the adjusting disk 36; the proportional mechanism 35 is engaged with the drive disk 38; the moving plate 32 slides on the slide rod 31, and the transmission disk 34 drives the moving plate 32 to move through the drive arm 33; the adjusting disk 36 adjusts the rotation ratio between the drive disk 38 and the transmission disk 34 through the proportional mechanism 35; the rocker arm 37 is a force-saving mechanism for driving the adjusting disk 36.

[0044] The proportional mechanism 35 includes an output disk 351, an input disk 352, a steel belt 353, a fixed rod 354, a threaded rod 355, and a threaded disk 356. The output disk 351 and the input disk 352 have the same structure, each including a fixed disk and a movable disk. The fixed disk and the movable disk are arranged opposite to each other. The fixed disk has the same structure as the movable disk, and the fixed disk is a spliced ​​structure of a disc and a frustum. Teeth are provided on the inclined surface of the frustum. The movable disk is coaxial and parallel to the fixed disk, and the inclined surfaces of the movable disk and the fixed disk with teeth are opposite to each other. The cross-section of the steel belt 353 is a spliced ​​structure of trapezoidal and rectangular sections, and teeth are also provided on the two inclined surfaces of the trapezoidal section of the steel belt 353. The teeth on the two inclined surfaces of the steel belt 353 mesh with the teeth on the inclined surfaces of the movable disk and the fixed disk.

[0045] In this configuration, the fixed and movable discs of the output disc 351 and input disc 352 are positioned oppositely. The output disc 351 is connected to the input disc 352 via a steel strip 353. The movable discs of the output disc 351 and the input disc 352 are connected via a fixed rod 354. The side of the fixed rod 354 has a threaded hole that is threadedly connected to a threaded rod 355. A threaded disc 356 is fixedly connected to the threaded rod 355 and engages with an adjusting disc 36. The fixed disc of the output disc 351 engages with a transmission disc 34, and the fixed disc of the input disc 352 engages with a drive disc 38. The fixed rod 354 connects to the output disc 352. The movable disc of the input disc 352 and the threaded disc 356 drive the threaded rod 355 to rotate. The threaded rod 355 drives the fixed rod 354 to move horizontally through the threaded hole, which in turn drives the movable discs of the output disc 351 and the input disc 352 connected to the fixed rod 354 to move. Since the fixed disc and the movable disc of the output disc 351 and the input disc 352 are in opposite positions, when the distance between the movable disc and the fixed disc of the output disc 351 increases, the distance between the movable disc and the fixed disc of the input disc 352 decreases; and vice versa. Therefore, the transmission ratio of the input disc 352 and the output disc 351 connected by the steel belt 353 can be proportionally adjusted.

[0046] The surface of the adjustment disc 36 is marked with graduations to facilitate setting a suitable transmission ratio.

[0047] Two clamps 4 are arranged in parallel relative to each other; each clamp 4 includes a fixed frame 41, a clamp 42, a lifting seat 43, and springs 44; both the clamp 42 and the lifting seat 43 are installed inside the fixed frame 41, and the clamp 42 and the lifting seat 43 are slidably engaged; one end of each spring 44 is installed on the upper surface of the lifting seat 43, and the other end is connected to the inner surface of the fixed frame 41.

[0048] Among them, the cross-section of the clamp 42 is a right trapezoid; the cross-section of the lifting seat 43 is a combination of a right trapezoid and a "convex" shape; the inclined waist of the right trapezoid in the cross-section of the clamp 42 fits with the inclined waist of the right trapezoid in the cross-section of the lifting seat 43; the top surface of the lifting seat 43 is provided with several teeth, and several springs 44 are provided on one side of the teeth of the lifting seat 43.

[0049] The fixed frame 41 has a slot inside; the clamp 42 has inserts on both sides, which slide in conjunction with the slots; the top of the fixed frame 41 has several openings, the position and number of which correspond to the teeth on the lifting seat 43 installed inside the fixed frame 41.

[0050] Among them, the teeth on the lifting seat 43 mesh with the drive disc 38;

[0051] The fixed frame 41 is used to limit the clamp 42, the lifting seat 43 and the spring 44. The clamp 42 is clamped to the edge of the material to be glued. When the material to be glued is squeezed against the clamp 42, the inclined surface of the clamp 42 and the lifting seat 43 is misaligned and slides. Since the lifting seat 43 is limited by the fixed frame 41, it can only move upward. During the upward movement of the lifting seat 43, the teeth set on the lifting seat 43 pass through the opening at the top of the fixed frame 41. At this time, the top surface of the clamp 4 forms a rack structure, and through the cooperation of the drive disk 38, it forms a force to drive the glue pump 2. The spring 44 is also compressed in this process, so that the lifting seat 43 can provide a downward thrust when it is reset.

[0052] The dispensing equipment also includes a positioning frame. The dispensing head 1, the glue pump 2, and the adjustment mechanism 3 are all fixed on the positioning frame, and the positioning frame slides with the clamp 4. The shape of the positioning frame is adapted to the fixed position required by the parts of the dispensing head 1, the glue pump 2, and the adjustment mechanism 3. The function of the positioning frame is to fix and limit the various parts.

[0053] A dispensing method using a dispensing device includes the following steps:

[0054] Step 1: Connect the glue inlet tube 12 of the dispensing equipment to the container storing the glue; and start the glue pump 2 by rotating the drive disk 38 to fill the glue inlet tube 12, glue pump 2, glue outlet tube 11 and dispensing head 1 with glue.

[0055] Step 2: Adjust the dispensing frequency according to the dispensing requirements. Start the adjustment disk 36 by rotating the joystick 37, and adjust it according to the scale on the adjustment disk 36.

[0056] Step 3: Clamp the material to be glued using the clamp 4, align the edge of the material to be glued with the clamp seat 42 of the clamp 4, and use the extrusion device to fix and clamp the material to the clamp 4.

[0057] Step 4: Move the positioning frame and apply adhesive.
