[0002] At present, after dispensing glue, the existing glue dispensing machine generally has residual glue on its dispensing needle, which needs to be cleaned before being put into use to avoid affecting the quality of later dispensing glue. However, the existing glue dispensing machine does not have the function of self-cleaning, and often needs to be cleaned manually, usually by manually scraping glue on the needle, which is inefficient and has poor cleanliness. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a bidirectional high-speed and high-precision glue cleaning device, which can automatically clean glue, clamp the glue needle from two directions, and clean glue from multiple angles of the glue needle.

[0004] The purpose of the present invention is achieved by the following technical solutions:

[0006] The clamping assembly includes two first clamps, two second clamps, a first clamp driving mechanism and a second clamp driving mechanism. The two first clamps are spaced apart in the X-axis direction; the two second clamps are spaced apart in the Y-axis direction; the first clamp driving mechanism is used to drive the two first clamps to move closer to or away from each other; the second clamp driving mechanism is used to drive the two second clamps to move closer to or away from each other.

[0007] Furthermore, a flexible material layer is provided on the inner side of the first clamping block and the second clamping block; the flexible material layer is foam.

[0009] Furthermore, one of the first clamping blocks or the second clamping block is provided with a through-hole; the receiving hopper is inserted into the clamping assembly through the through-hole.

[0010] Furthermore, the two second clamping blocks are distributed above the two first clamping blocks.

[0011] Furthermore, the bidirectional high-speed and high-precision glue cleaning device also includes a second guide component, which is distributed between the first guide component and the traction component. The first guide component is used to guide the glue cleaning tape in and out of the clamping component in a horizontal direction; the second guide component is used to guide the glue cleaning tape in a vertical direction into the waste collection box.

[0012] Furthermore, the unloading assembly includes two unloading rollers, and the two unloading rollers are used to wind the cleaning tape.

[0013] Furthermore, the first guiding assembly includes a first roller group and a second roller group, and the rotation axes of the first roller group and the second roller group are parallel to the vertical direction; the first roller group is arranged between the discharge assembly and the clamping assembly; the second roller group is arranged between the clamping assembly and the traction assembly; and the cleaning tape is used to be wound around the first roller group and the second roller group.

[0014] Furthermore, the traction assembly includes a motor, two gears and an elastic component, the rotating shaft of the motor is synchronously connected to one of the gears; the two gears are meshed with each other; the elastic component is used to provide elastic stress to bring the two gears closer to each other; the cleaning tape is used to be inserted between the two gears.

[0015] Furthermore, the discharge assembly, the clamping assembly, the traction assembly and the first guide assembly are each provided with two groups.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the clamping assembly of the clamping assembly can clamp the glue needle.

The clamping surface of the glue needle can be cleaned in a targeted manner, and the glue cleaning accuracy is high.

[0017] In addition, since the clamping assembly has two first clamping blocks distributed along the X-axis direction and two second clamping blocks distributed along the Y-axis direction, when clamping the glue needle, the two first clamping blocks can clamp the two surfaces of the glue needle in the X-axis direction, and the two second clamping blocks can clamp the two surfaces of the glue needle in the Y-axis direction, so that the cleaning tape can enter along the X-axis or Y-axis direction to clean the corresponding surface of the glue needle, and the other surface of the glue needle can be removed by the friction between the glue needle and the corresponding clamping blocks under the drive of the cleaning tape.

DETAILED DESCRIPTION

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0025] like Figure 1-5 A bidirectional high-speed and high-precision adhesive cleaning device is shown, comprising a discharge assembly 10, a clamping assembly 20, a traction assembly 50, a first guide assembly and a waste collection box 60, wherein the discharge assembly 10, the clamping assembly 20 and the traction assembly 50 can be mounted on a machine body. Specifically, the discharge assembly 10 can be wound with adhesive cleaning tape, and the traction assembly 50 is used to provide traction force, and under the action of the traction force, the adhesive cleaning tape can pass through the first guide assembly and the clamping assembly 20 in sequence. The first guide assembly is used to guide the adhesive cleaning tape to enter and exit the clamping assembly 20 in a horizontal direction.

[0026] In addition, the clamping assembly 20 may include two first clamps 21, two second clamps 23, a first clamp driving mechanism 22 and a second clamp driving mechanism 24. The two first clamps 21 are spaced apart in the X-axis direction, and the two second clamps 23 are spaced apart in the Y-axis direction. The first clamp driving mechanism 22 can drive the two first clamps 21 to move closer to or away from each other, and the second clamp driving mechanism 24 can drive the two second clamps 23 to move closer to or away from each other.

[0027] On the basis of the above structure, when cleaning the residual glue on the glue needle, the glue needle can be clamped in the clamping component 20, and by starting the traction component 50, the traction force provided by the traction component 50 can drive the cleaning tape to be released from the discharge component 10, and under the action of the traction force, the cleaning tape can be guided in and out of the clamping component 20 by the first guide component, and the surface of the glue needle clamped by the clamping component 20 can be cleaned. The clamping surface of the glue needle can be cleaned in a targeted manner, and the glue cleaning accuracy is high.

[0028] Specifically, when clamping, the glue needle can be placed between the two first clamping blocks 21 and the two second clamping blocks 23. Driven by the first clamping block driving mechanism 22 and the second clamping block driving mechanism 24, the two first clamping blocks 21 and the two second clamping blocks 23 can clamp the glue needle at the same time. Therefore, when clamping the glue needle, the two first clamping blocks 21 can clamp the two surfaces of the glue needle in the X-axis direction, and the two second clamping blocks 23 can clamp the two surfaces of the glue needle in the Y-axis direction, so that the cleaning tape can enter along the X-axis or Y-axis direction to clean the corresponding surface of the glue needle, and the other surface of the glue needle can be removed by the friction between the glue needle and the corresponding clamping block driven by the cleaning tape. In this way, the cleaning of the glue needle is cleaner, the cleaning speed is faster, and the cleaning accuracy is higher.

[0029] In this embodiment, the adhesive cleaning tape enters the clamping assembly 20 along the Y-axis direction under the guidance of the first guide assembly. When cleaning the adhesive, the adhesive cleaning tape is drawn out from the material discharge assembly 10 and guided by the first guide assembly to enter between the two first clamping blocks 21. The adhesive cleaning tape can be attached to the inner side surface of the first clamping block 21 under the action of traction force, and the corresponding two second clamping blocks 23 can be distributed above or below the two first clamping blocks 21. The two first clamping blocks 21 can clamp the adhesive needle from the X-axis direction, and the two second clamping blocks 23 can clamp the adhesive needle from the Y-axis direction above or below the first clamping block 21. In this way, the adhesive cleaning tape section can rub with the surface of the adhesive needle to take away the residual adhesive on the surface of the adhesive needle, and clean the surface of the adhesive needle in the X-axis direction, while the surface of the adhesive needle in the Y-axis direction can be cleaned by the friction between the second clamping block 23 and the adhesive needle. Since the first clamping block 21 and the second clamping block 23 are staggered up and down, the conveying of the adhesive cleaning tape is not affected.

[0030] It should be noted that the cleaning tape in this embodiment can be implemented by using a dust-free cloth tape in the prior art. The X-axis direction refers to the length direction of the machine body, and the Y-axis direction refers to the width direction of the machine body.

[0031] More specifically, a flexible material layer can be provided on the inner side of the first clamping block 21 and the second clamping block 23, so that when the two first clamping blocks 21 and the two second clamping blocks 23 are close to each other to clamp the rubber needle, the contact with the rubber needle is flexible to prevent damage to the rubber needle. Specifically, the above-mentioned flexible material layer is foam. Compared with other flexible materials such as silicone, foam has better flexibility and is easier to deform, so it is easy to fit on the surface of the rubber needle. The foam inside the two second clamping blocks 23 can clean the surface of the rubber needle in the Y-axis direction while clamping the rubber needle, and the cleaning effect is better.

[0032] Furthermore, the above-mentioned clamping assembly 20 also includes a material receiving hopper 25, which is connected to the bottom of the clamping assembly 20 and is used to receive residual glue. That is, when cleaning the glue, the glue needle is clamped between the two first clamping blocks 21 and the two second clamping blocks 23, and the material receiving hopper 25 can be located below the glue needle. In this way, when the glue cleaning belt moves and the glue is cleaned, some residual glue will fall and be received by the material receiving hopper 25 below the clamping assembly 20, so as to prevent the residual glue from falling directly on other equipment of the body and affecting the operation of other equipment.

[0033] Specifically, when the two second clamping blocks 23 are distributed above the two first clamping blocks 21, a through-interface may be provided on one of the first clamping blocks 21, and the receiving hopper 25 is inserted into the clamping assembly 20 through the through-interface. When installing the receiving hopper 25, the receiving hopper 25 can be inserted into the clamping assembly 20 through the through-interface, and the other end of the receiving hopper 25 can form a hand-held portion that is easy to operate, so that the receiving hopper 25 can be easily taken in and out. The receiving hopper 25 can be located at the bottom of the clamping interval, and the receiving hopper 25 can receive residual glue during glue cleaning. After the glue cleaning is completed, the receiving hopper 25 can be taken out from the first clamping block 21, and the residual glue in the receiving hopper 25 can be cleaned up in a centralized manner, and it is easy to disassemble and assemble.

[0034] When the two second clamping blocks 23 are distributed below the two first clamping blocks 21 , the above-mentioned through-port can be provided on one of the second clamping blocks 23 to ensure that the receiving hopper 25 is located below the clamping assembly 20 after assembly.

[0035] Of course, the first clamping block driving mechanism 22 and the second clamping block driving mechanism can be implemented by a cylinder in the prior art, and the piston rod of the cylinder can be extended and retracted to achieve the two clamping blocks to move closer to or farther from each other. Of course, the clamping assembly 20 can also be directly selected as other clamps such as pneumatic fingers or clamps in the prior art.

[0036] Furthermore, the bidirectional high-speed and high-precision glue cleaning device also includes a second guide component 40, which is distributed between the first guide component and the traction component 50. Specifically, the first guide component is used to guide the glue cleaning tape in and out of the clamping component 20 in the horizontal direction, and the second guide component 40 is used to guide the glue cleaning tape in the vertical direction into the waste collection box 60.

[0037] That is, when cleaning the glue, since the cleaning surface of the cleaning tape is in a vertical state, the contact area between the cleaning surface and the glue needle is large, and thus the first guide assembly can guide the cleaning tape to be transported horizontally, and the cleaning surface of the cleaning tape is in a vertical state and enters between the two first clamping blocks 21 and adheres to the surface of the first clamping block 21, so that the cleaning area is larger.

[0038] When the cleaning tape is transported in the horizontal direction, there will be residual glue on the cleaning tape led out by the clamping component 20. When transported horizontally, more residual glue will fall on the machine body. Therefore, the second guiding component 40 can guide the cleaning tape to fall vertically to the waste collecting box 60. The waste collecting box 60 directly receives the cleaning tape, which reduces the dragging section of the cleaning tape on the machine body. The residual glue also falls directly into the waste collecting box 60, and the cleaning effect is better.

[0039] Furthermore, the discharge assembly 10 includes two discharge rollers 11, and the two discharge rollers 11 are used for winding the cleaning tape. That is, when cleaning the glue, two cleaning tapes can be discharged from the discharge roller 11 at the same time. When entering the clamping assembly 20 of the clamping assembly 20, the two cleaning tapes can be respectively attached to the two side walls of the clamping assembly 20, and the glue can be cleaned on both sides of the glue needle at the same time, and the glue cleaning effect is better.

[0040] Furthermore, the above-mentioned first guide assembly includes a first roller group 31 and a second roller group 32, and the rotation axes of the first roller group 31 and the second roller group 32 are parallel to the vertical direction. Specifically, the first roller group 31 is arranged between the discharge assembly 10 and the clamping assembly 20, and the second roller group 32 is arranged between the clamping assembly 20 and the traction assembly 50; the cleaning tape can be wound around the first roller group 31 and the second roller group 32.

[0041] When guiding the cleaning tape, the cleaning tape can be led out from the discharge component 10, wound around the first roller group 31, and enter the clamping component 20, and received by the second roller group 32. Since the rotation axes of the first roller group 31 and the second roller group 32 are parallel to the vertical direction, the cleaning surface of the cleaning tape can be vertically wound around the first roller group 31 and the second roller group 32. Therefore, the cleaning surface of the cleaning tape section located in the clamping component 20 is in vertical contact with the glue needle, the contact area is larger, and the cleaning effect is better.

[0042] In the case where the material discharging assembly 10 is composed of two material discharging rollers 11, both the first roller group 31 and the second roller group 32 can be made of two rollers, and the rollers can be pivotally connected to the machine body through a guide shaft.

[0043] Furthermore, the second guide assembly 40 includes a third roller group, the rotation axis of the third roller group is parallel to the horizontal direction, and the cleaning tape can be wound around the third roller group. Since the rotation axis of the third roller group is parallel to the horizontal direction, when the cleaning tape is wound around the third roller group, the cleaning surfaces are parallel, and the entire cleaning tape can fall vertically.

[0044] Specifically, during actual assembly, the distance between the third roller group and the second roller group 32 needs to be long enough so that the cleaning tape led out from the second roller group 32 has a sufficiently long buffer section when it is wound on the third roller group to prevent the cleaning tape from getting stuck due to the change in conveying direction.

[0045] Furthermore, the traction assembly 50 in this embodiment includes a motor 51, two gears 52 and an elastic component 53, and the rotating shaft of the motor 51 is synchronously connected to one of the gears 52, and the two gears 52 are meshed with each other. Specifically, the elastic component 53 is used to provide elastic stress to make the two gears 52 approach each other, and the cleaning tape is used to pass between the two gears 52.

[0046] In this way, when traction is performed, the cleaning tape can be led out by the discharge roller 11, enter the clamping assembly 20 through the first roller group 31, and then be led out of the clamping assembly 20 by the second roller group 32, and then guided by the third roller group to between the two gears 52, and the motor 51 is started. The rotation of the shaft of the motor 51 can drive one of the gears 52 to rotate, and then drive the other gear 52 to transmit. The rotation of the two gears 52 can drive the cleaning tape to be transported downward, providing traction to pull the cleaning tape on the discharge roller 11 for continuous output.

[0047] The elastic stress provided by the elastic component 53 can keep the gear 52 clamped with the cleaning tape and keep the tension and relaxation appropriate. A rotating arm 54 is rotatably connected to the body, and one gear 52 is pivotally connected to the rotating arm 54; one end of the elastic component 53 can be connected to the body, and the other end of the elastic component 53 can abut against the side of the rotating arm 54 away from the other gear 52, so that the elastic component 53 can provide elastic stress to keep the gear 52 on the rotating arm 54 in a state of meshing with the other gear 52. Of course, the elastic component 53 can be a spring.

[0048] Furthermore, in the present embodiment, the above-mentioned discharge assembly 10, clamping assembly 20, traction assembly 50, first guide assembly, and second guide assembly 40 are each provided with two groups, that is, two groups of discharge assemblies 10 are provided on the machine body to simultaneously wind the cleaning tape, and the cleaning tape discharged by the corresponding discharge assembly 10 can enter and exit the clamping assembly 20 of the corresponding clamping assembly 20 through the corresponding first guide assembly, and then be guided to the middle waste collection box 60 through the corresponding second guide assembly 40, so that the cleaning operation can be carried out on both sides at the same time, and the cleaning efficiency is higher.

[0049] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
