Description

Technical Field

[0001] The present invention relates to the technical field of dispensing, and particularly relates to a dispensing machine with a dispensing valve deviation correction mechanism. Background Art

[0002] Dispensing is a process of applying, encapsulating, or dripping electronic glue, oil, or other liquids onto products to make the products play roles such as adhesion, encapsulation, insulation, fixation, and smooth surface.

[0003] The patent application No. CN202410275578.1 discloses a dispensing device of a dispensing machine, including a base. A moving mechanism is arranged on the top of the base, and a support plate is arranged on the top of the moving mechanism. A fixing mechanism is arranged on the top of the support plate. Support columns are connected to both sides of the base through bolts, and a translation mechanism is arranged between the opposite sides of the two support columns. A support block is arranged on one side of the translation mechanism, and a hydraulic rod is connected to the bottom of the support block through bolts. A fixing block is connected to the bottom of the hydraulic rod through bolts, and a dispensing mechanism is arranged on one side of the fixing block. The dispensing mechanism includes a glue storage cylinder, a cylinder body, a piston plate, and a flow extension rod. The glue storage cylinder is connected to the fixing block through bolts, and a connecting rod is connected between the glue storage cylinder and the cylinder body. The piston plate is slidably connected to the inner wall of the glue storage cylinder. The present invention can prevent the glue remaining on the dispensing mechanism from dripping onto the material, resulting in more glue adhering to the material and causing waste of the glue.

[0004] Since the dispensing machine has strict requirements for the dispensing position, once the dispensing position deviates, it will cause deviation effects, resulting in a large number of unqualified products, increasing production costs, and affecting product quality and production efficiency.

[0045] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present invention.

When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0047] As Figures 1 to 17 shown, a dispensing machine with a dispensing valve alignment mechanism according to the present invention includes: a machine table 1; a fixed box 5 fixedly installed on the machine table 1; a dispensing mechanism 2 for dispensing glue on a workpiece; a fixing mechanism 3 for fixing the workpiece; and an alignment mechanism 4 for aligning the dispensing mechanism 2.

[0048] When dispensing glue on a workpiece, it is necessary to first fix the workpiece through the fixing mechanism 3, and then dispense glue through the dispensing mechanism 2. During the dispensing process, the dispensing head 22 in the dispensing mechanism 2 is aligned through the alignment mechanism 4, thereby ensuring the accuracy of the dispensing position and improving the dispensing quality.

[0049] The fixing mechanism 3 includes: a positioning plate 31 for positioning and placing the workpiece, and the positioning plate 31 is U-shaped; a moving component 32 for driving the positioning plate 31 to move; a clamping component 33 for clamping and fixing the workpiece; the moving component 32 includes: a limit opening formed on the machine table 1, a movable seat 321 slidably installed in the limit opening, a limit rod slidably installed on the movable seat 321, and the movable seat 321 can be limited through the arrangement of the limit rod, and the limit rod is fixedly installed in the limit opening; a support cylinder 322 and a transmission rack 323 fixedly connected to the movable seat 321, there are two support cylinders 322, symmetrically arranged on the movable seat 321, and the positioning plate 31 is fixedly installed on the tops of the two support cylinders 322; a transmission gear 324 meshed with the transmission rack 323, and the transmission gear 324 is rotatably installed in the machine table 1; a driven bevel gear 325 coaxially connected to the transmission gear 324; a driving bevel gear 326 meshed with the driven bevel gear 325; and a driving unit 327 for driving the driving bevel gear 326 to rotate.

[0050] When fixing the workpiece, first place the workpiece inside the positioning plate 31. Through the setting of the positioning plate 31, the workpiece can be limited in the moving direction of the positioning plate 31, avoiding the deviation of the workpiece in the moving direction of the positioning plate 31, improving the stability of the workpiece during dispensing. Then start the driving unit 327 to drive the workpiece to move to the dispensing position for dispensing.

[0051] The driving unit 327 includes: a movable rod 3271 fixedly connected to the movable frame 253; a movable tube 3272 fixedly connected to the movable rod 3271; a rotating rod 3273 rotatably installed on the fixed box 5 and the machine table 1, and the movable tube 3272 is sleeved and installed on the rotating rod 3273; a guiding groove 3274 opened on the rotating rod 3273; a first rolling member 3275 rotatably installed inside the movable tube 3272; the guiding groove 3274 is composed of a spiral groove and a straight groove, and the spiral groove is communicated with the straight groove; the first rolling member 3275 is rollingly installed inside the guiding groove 3274.

[0052] When starting the power source 252, it can drive the threaded rod 251 to rotate, thereby driving the movable frame 253 to move axially along the threaded rod 251. When the movable frame 253 moves downward, it can drive the movable rod 3271 to move downward, and the movable rod 3271 drives the movable tube 3272 to move downward, causing the first rolling member 3275 to roll inside the guiding groove 3274.

[0053] The first rolling member 3275 first rolls in the spiral groove, thereby driving the rotating rod 3273 to rotate. The rotating rod 3273 drives the driving bevel gear 326 to rotate, the driving bevel gear 326 drives the driven bevel gear 325 to rotate, the driven bevel gear 325 drives the transmission gear 324 to rotate, the transmission gear 324 drives the transmission rack 323 to move, the transmission rack 323 drives the movable seat 321 to move, the movable seat 321 drives the support cylinder 322 to move, and the support cylinder 322 drives the positioning plate 31 to move, thereby driving the workpiece to move to the dispensing position, thus realizing the automatic feeding of the workpiece.

[0054] When the workpiece moves to the dispensing position, the first rolling member 3275 enters the straight groove at this time, and the rotating rod 3273 no longer rotates at this time, so that the workpiece no longer moves. At the same time, the movable frame 253 continues to move downward, thereby driving the dispensing mechanism 2 to move downward and dispensing glue on the workpiece.

[0055] After the dispensing is completed, the movable frame 253 drives the dispensing mechanism 2 to reset upward. At the same time, it can drive the positioning plate 31 to reset, thus realizing the discharging of the dispensed workpiece, facilitating the removal of the dispensed workpiece and replacing the workpiece to be dispensed.

[0056] It is supplemented here that the first rolling member 3275 is preferably a bull eye ball.

[0057] The clamping assembly 33 includes: a fixed frame 331 fixedly installed on the machine table 1, on which a sliding frame is slidably installed, and the sliding frame is fixedly connected to the support cylinder 322; a liquid storage pipe 332 fixedly installed on the sliding frame; a first piston plate 333 slidably installed in the liquid storage pipe 332, and the first piston plate 333 divides the liquid storage pipe 332 into two independent spaces, one space can store air and the other space stores hydraulic oil; a clamping rod 334 fixedly connected to the first piston plate 333, the clamping rod 334 penetrates the side wall of the liquid storage pipe 332, and a sealing ring is installed at the penetration of the liquid storage pipe 332, so as to reduce the air in the liquid storage pipe 332 from discharging from the penetration of the liquid storage pipe 332; a clamping plate 335 fixedly connected to the clamping rod 334; a return spring 336 for driving the clamping plate 335 to reset, one end of the return spring 336 is fixedly connected to the first piston plate 333, and the other end of the return spring 336 is fixedly connected to the inner wall of the liquid storage pipe 332; a liquid supply unit 337 for supplying hydraulic oil into the liquid storage pipe 332; the liquid supply unit 337 includes: a second piston plate 3371 slidably installed in the support cylinder 322; a connecting rod 3372 fixedly connected to the second piston plate 3371, and the connecting rod 3372 is fixedly connected to the fixed frame 331; a liquid guide pipe 3373 connecting the support cylinder 322 and the liquid storage pipe 332.

[0058] When the positioning plate 31 drives the workpiece to move towards the dispensing position, the two support cylinders 322 move synchronously, causing the second piston plate 3371 to slide in the support cylinder 322, thereby squeezing the hydraulic oil in the support cylinder 322. The hydraulic oil enters the liquid storage pipe 332 through the liquid guide pipe 3373. When the hydraulic oil in the liquid storage pipe 332 gradually increases, the hydraulic oil generates a squeezing force on the first piston plate 333. The first piston plate 333 drives the clamping rod 334 to move and deforms the return spring 336. The clamping rod 334 drives the clamping plate 335 to move. When the positioning plate 31 drives the workpiece to move to the dispensing position, the two clamping plates 335 just abut against the workpiece, thus realizing the clamping and fixing of the workpiece, further improving the stability of the workpiece during dispensing, and preventing the workpiece from shifting during dispensing and affecting the dispensing accuracy.

[0059] When the workpiece moves to the dispensing position, at the same time, the clamping plate 335 completes the clamping and fixing of the workpiece. At this time, the first rolling member 3275 just enters the straight groove, and at this time the rotating rod 3273 no longer rotates, so that the workpiece no longer moves, that is, the support cylinder 322 no longer moves, and thus no longer supplies hydraulic oil into the liquid storage pipe 332, so that the clamping plate 335 maintains the state of clamping the workpiece; at the same time, the movable frame 253 continues to move downward, so as to drive the dispensing mechanism 2 to move downward to dispense the workpiece.

[0060] After the workpiece is dispensed, start the power source 252 to rotate in the reverse direction, so that the movable frame 253 moves upward, and then drive the dispensing mechanism 2 to reset upward. At the same time, the support cylinder 322 can be driven to reset. At this time, the second piston plate 3371 slides in the support cylinder 322 again and generates suction, so as to suck the hydraulic oil in the liquid storage pipe 332 into the support cylinder 322 through the liquid guide pipe 3373. At this time, under the elastic force of the return spring 336, the first piston plate 333 can be driven to reset, and then the clamping plate 335 is driven to reset, so that the clamping plate 335 releases the clamping state of the workpiece. At the same time, the support cylinder 322 drives the positioning plate 31 to reset, and then the dispensing of the dispensed workpiece is realized, which is convenient for taking out the dispensed workpiece and replacing the workpiece to be dispensed.

[0061] Through the setting of the fixing mechanism 3, while realizing the automatic feeding of the workpiece, the workpiece is automatically clamped and fixed. After the workpiece is dispensed, while realizing automatic glue discharging, the fixing state of the workpiece is automatically released, without manual fixing, thus improving the work efficiency.

[0062] The fixing mechanism 3 further includes: a jet head 35, which is fixedly installed on the sliding frame; an air guide pipe 34 connecting the jet head 35 and the liquid storage pipe 332.

[0063] When the support cylinder 322 moves towards the dispensing position, the first piston plate 333 slides in the liquid storage pipe 332, thereby squeezing the air in the liquid storage pipe 332. The air enters the jet head 35 through the air guide pipe 34 and is sprayed on the surface of the workpiece, so as to clean the dust on the surface of the workpiece, and then the pretreatment before dispensing the workpiece is realized, improving the dispensing effect.

[0064] The dispensing mechanism 2 includes: a mounting pipe 21 fixedly connected to the movable plate 43; a dispensing head 22 slidably mounted in the mounting pipe 21; a connecting pipe 23 communicating with the dispensing head 22, the top end of the connecting pipe 23 is fixedly connected to the movable plate 43; a reset assembly 24 for driving the connecting pipe 23 to reset; a glue storage tank 27 communicating with the connecting pipe 23, a pump body is installed in the glue storage tank 27, and the pump body is communicated with the connecting pipe 23 through a hose; a power assembly 25 for driving the dispensing head 22 to move; a drip prevention assembly 26 for preventing the glue in the dispensing head 22 from dripping; the power assembly 25 includes: a threaded rod 251 rotatably mounted in the fixed box 5; a power source 252 for driving the threaded rod 251 to rotate, the power source 252 is fixedly installed on the fixed box 5; a movable frame 253 threadedly connected to the threaded rod 251, a sliding opening is provided on the fixed box 5, and through the setting of the sliding opening, the movable frame 253 can be limited, improving the stability of the movable frame 253 during the moving process; a limiting member 254 for limiting the movable frame 253; a moving module 255 fixedly installed on the movable frame 253.

[0065] A glue outlet hole one 231 is formed on the side wall of the connecting pipe 23; a glue outlet hole two 221 is formed on the inner wall of the dispensing head 22; a cavity 222 is formed on the side wall of the dispensing head 22; the glue outlet hole two 221 communicates with the cavity 222; both the glue outlet hole one 231 and the glue outlet hole two 221 are provided with a plurality of them, and they are of the same size, and the adjacent glue outlet hole one 231 and glue outlet hole two 221 can only move relatively in the up-and-down straight line direction.

[0066] The limiting member 254 includes: a guiding rod penetrating and installed on the side wall of the movable frame 253; a guide rail fixedly installed on the fixed box 5; a guiding block slidably installed on the guide rail; the guiding block is fixedly installed on the movable frame 253; both ends of the guiding rod are fixedly installed in the fixed box 5, and two groups of the guiding rod, the guiding block and the guide rail are symmetrically arranged, so as to provide a uniform limiting effect on the movable frame 253 and further improve the stability of the movable frame 253 during the moving process.

[0067] The moving module 255 includes: a horizontal linear moving module 255 and a vertical linear moving module 255.

[0068] When dispensing glue on the workpiece, first start the moving module 255 to adjust the dispensing head 22 horizontally and vertically, so that the dispensing head 22 moves to the preset dispensing position, and start the power source 252 to drive the threaded rod 251 to rotate. Under the limiting action of the limiting member 254, the threaded rod 251 drives the movable frame 253 to move downward along the axial direction of the threaded rod 251, so as to drive the dispensing head 22 to move downward.

[0069] When the bottom end of the dispensing head 22 abuts against the workpiece, the connecting pipe 23 continues to move downward, so that the glue outlet hole one 231 communicates with the glue outlet hole two 221. At this time, start the pump body, and the glue in the glue storage tank 27 can be conveyed into the connecting pipe through the hose, and enter the cavity 222 through the glue outlet hole one 231 and the glue outlet hole two 221, and then be dot-coated on the surface of the workpiece through the dispensing head 22.

[0070] When the dispensing head 22 moves, it generates relative sliding with the connecting pipe 23, so as to adjust the positions of the adjacent glue outlet hole one 231 and glue outlet hole two 221, that is, control the communicating part of the glue outlet hole one 231 and the glue outlet hole two 221, and further realize the control of the glue output of the dispensing head 22, so as to meet the requirements of different glue output amounts.

[0071] Specifically, when the adjacent glue outlet hole one 231 and the glue outlet hole two 221 are completely aligned, the maximum connected part between the glue outlet hole one 231 and the glue outlet hole two 221 is achieved. At this time, the glue output of the glue dispensing head 22 is the largest, that is, the glue dispensing amount is the largest. When the adjacent glue outlet hole one 231 and the glue outlet hole two 221 are misaligned, the connected part between them decreases. At this time, the glue output of the glue dispensing head 22 decreases, that is, the glue dispensing amount decreases. When the adjacent glue outlet hole one 231 and the glue outlet hole two 221 are completely staggered, there is no longer a connected part between them. At this time, the glue liquid no longer enters the glue dispensing head 22, and the glue dispensing head 22 cannot perform glue dispensing. It can be seen that by the relative movement of the adjacent glue outlet hole one 231 and the glue outlet hole two 221, the glue dispensing amount of the glue dispensing head 22 can be controlled, so as to meet the requirements of different glue dispensing amounts.

[0072] In addition, when the adjacent glue outlet hole one 231 and the glue outlet hole two 221 are completely staggered, there is no longer a connected part between them. At this time, the glue liquid no longer enters the glue dispensing head 22, and the glue dispensing head 22 cannot perform glue dispensing. Thus, when the glue dispensing of the workpiece is completed, the glue dispensing head 22 resets upward. At this time, the adjacent glue outlet hole one 231 and the glue outlet hole two 221 are completely staggered, thus avoiding the problem of glue liquid dripping from the connecting pipe 23 into the inner cavity of the glue dispensing head 22, thereby playing a role in preventing dripping. On the one hand, it prevents the problem of glue liquid dripping inside the glue dispensing head 22 from causing pollution, and on the other hand, it reduces glue liquid waste and lowers the production cost.

[0073] It is supplemented here that the power source 252 is preferably a motor.

[0074] The reset component 24 includes: a movable ring 241 fixedly sleeved on the glue dispensing head 22; a slider 242 fixedly installed on the movable ring 241; a guide rod 243 slidably connected to the slider 242; a connecting spring 244 for driving the glue dispensing head 22 to reset; a chute is formed on the inner wall of the installation pipe 21, the slider 242 is slidably installed in the chute, and both ends of the guide rod 243 are fixedly installed in the chute. One end of the connecting spring 244 is fixedly connected to the slider 242, and the other end is fixedly connected to the inner wall of the chute.

[0075] When the bottom end of the glue dispensing head 22 abuts against the workpiece, the installation pipe 21 continues to move downward, thereby driving the connecting spring 244 to stretch. At this time, through the settings of the slider 242, the chute, and the guide rod 243, the connecting pipe 23 and the glue dispensing head 22 can only perform relative movement in the up and down linear direction.

[0076] When the glue dispensing is completed, the glue dispensing head 22 is separated from the workpiece. At this time, under the elastic force of the connecting spring 244, the glue dispensing head 22 can be driven to reset.

[0077] The drip-proof assembly 26 includes: a bladder 261 installed inside the installation pipe 21, the top of the bladder 261 is fixedly connected to the movable plate 43, and the bottom of the bladder 261 is fixedly connected to the movable ring 241; a glue guide pipe 262 connecting the bladder 261 and the dispensing head 22.

[0078] When the dispensing head 22 is used for the first time, when the bottom end of the dispensing head 22 abuts against the workpiece, the movable plate 43 continues to move downward, thereby driving the bladder 261 to be compressed. At this time, the air in the bladder 261 is discharged, so that the inside of the dispensing head 22 can be cleaned, thus realizing the pre-cleaning before the use of the dispensing head 22 and avoiding dust adhering to the inside of the dispensing head 22, which affects the dispensing effect.

[0079] After the dispensing is completed, the dispensing head 22 is separated from the workpiece. At this time, under the elastic force of the connecting spring 244, the dispensing head 22 is driven to reset. At the same time, the bladder 261 is not extruded by the movable plate 43 and gradually recovers. During the recovery process of the bladder 261, the residual glue in the dispensing head 22 can be sucked into the bladder 261, which plays a role in preventing the dripping of the dispensing head 22, thus avoiding the problem that the residual glue in the dispensing head 22 drips out, resulting in waste of glue and pollution of the machine 1.

[0080] It should be added here that the bladder 261 has a certain elasticity, and when the bladder 261 recovers, it can assist the dispensing head 22 to reset.

[0081] The deviation correction mechanism 4 includes: a mounting plate 41 fixedly installed on the moving module 255; a mounting hole opened on the mounting plate 41; an equal-height bolt 42 penetrating through the mounting hole; a movable plate 43 threadedly connected to the equal-height bolt 42; a positioning cylinder 44 fixedly connected to the movable plate 43; a positioning rod 47 fixedly installed on the positioning plate 31; a balance assembly 45 for keeping the mounting plate 41 and the movable plate 43 balanced; a centering assembly 46 for driving the movable plate 43 to be centered; the balance assembly 45 includes: a support tube 451 fixedly installed on the movable plate 43; a support rod 453 slidably installed inside the support tube 451; a support spring 452 fixedly installed inside the support cylinder 322; a rolling member two 454 rotatably installed at the end of the support rod 453.

[0082] Both the positioning cylinder 44 and the positioning rod 47 are provided with a plurality of them, and the inner cavity of the positioning cylinder 44 matches the positioning rod 47, and the bottom end of the positioning cylinder 44 is in a trumpet shape, so as to better dock with the positioning rod 47.

[0083] Since the inner diameter of the mounting hole for installing the equal-height bolt 42 is larger than the outer diameter of the equal-height bolt 42, the movable plate 43 threadedly connected to the equal-height bolt 42 can move back and forth and left and right relative to the mounting plate 41, and then drive the positioning cylinder 44 and the dispensing head 22 to be finely adjusted in the front, back, left and right directions.

[0084] There are multiple sets of balance components 45, which are distributed in a rectangular array on the movable plate 43. Through the elastic force of the support springs 452, a uniform support force can be provided for the mounting plate 41.

[0085] In addition, the threaded length of the equal-height bolts 42 is equal to the bolt length, which can provide a more uniform tightening force, ensuring the stability and reliability of the connection. By tightening the equal-height bolts 42 by the same number of turns, the mounting plate 41 and the movable plate 43 can be kept parallel to each other, and thus the dispensing head 22 is in a horizontal state, avoiding tilting during dispensing.

[0086] Through the setting of the rolling element two 454, when the mounting plate 41 and the movable plate 43 move relative to each other, the moving process can be smoother.

[0087] It should be added here that the rolling element two 454 is preferably a bull eye ball.

[0088] The centering component 46 includes: a fixed seat 461 fixedly installed on the movable plate 43; a mounting groove opened on the mounting plate 41; a fixed rod 462 fixedly installed on the fixed seat 461; a movable cylinder 463 sleeved on the fixed rod 462; a rolling element three 465 rotatably installed at the end of the movable cylinder 463; a linkage spring 464 fixedly installed inside the movable cylinder 463, and the other end of the linkage spring 464 is fixedly connected to the fixed rod 462; the mounting groove is opened at the center of the bottom of the mounting plate 41, and the rolling element three 465 abuts against the inner wall of the mounting groove.

[0089] There are multiple sets of the fixed rod 462, the movable cylinder 463, the rolling element three 465, and the linkage spring 464, which can support the mounting plate 41 from multiple directions. When the mounting plate 41 and the movable plate 43 are displaced relative to each other under an external force, the corresponding linkage spring 464 can be deformed. When the external force disappears, through the elastic force of the linkage spring 464, the mounting plate 41 and the movable plate 43 can be driven to reset.

[0090] It should be added here that the rolling element three 465 is preferably a bull eye ball.

[0091] When the dispensing head 22 moves downward to dispense glue on the workpiece, the deviation rectifying mechanism 4 can be driven to move downward. Under normal circumstances, the positioning cylinder 44 is completely aligned with the corresponding positioning rod 47, that is, the dispensing head 22 is completely aligned with the dispensing position on the workpiece. At this time, when the positioning cylinder 44 moves downward, it can directly sleeve on the outside of the positioning rod 47.

[0092] After the precision of the moving module 255 and the fixing mechanism 3 is superimposed, it will cause the positioning cylinder 44 and the positioning rod 47 not to be completely aligned when they are docked. After the dispensing head 22 is moved to the preset position by the moving assembly 32, the dispensing head 22 and the dispensing position on the workpiece only need to be finely adjusted. At this time, the positioning cylinder 44 moves downward, and the flared opening at the bottom of the positioning cylinder 44 abuts against the positioning rod 47. When the positioning cylinder 44 continues to move downward, through the inclined surface setting on the inner wall of the flared opening, the positioning cylinder 44 can be driven to move relative to the positioning rod 47 by a little bit, realizing the complete alignment of the positioning cylinder 44 and the positioning rod 47, and further making the dispensing head 22 and the dispensing position on the workpiece completely aligned.

[0093] Through the setting of the deviation correction mechanism 4 of the present invention, the position of the dispensing head 22 can be automatically corrected, so that the dispensing head 22 and the dispensing position on the workpiece are completely aligned, improving the dispensing accuracy and ensuring the dispensing quality.
