Description

Technical Field

[0001] The utility model belongs to the technical field of glue spraying equipment, and in particular relates to a nozzle wet wiping structure, a nozzle wiping mechanism and a glue spraying system. Background Art

[0002] In the production process of some semiconductor products, glue needs to be sprayed on the product by a glue sprayer before subsequent processes such as mounting, welding or baking are carried out. However, after working for a long time, a lot of glue will remain at the nozzle of the existing glue sprayer, which will not only cause glue waste, but also may drip and contaminate the product, affecting the glue spraying effect and product quality. Therefore, the nozzle needs to be wiped frequently.

[0003] The existing nozzle wiping mechanism is located at the initial position, and the object to be sprayed with glue is located at the glue spraying position. The nozzle wiping mechanism is provided with two slots, a wiping material is placed on the first slot, and the second slot is the waste glue discharge position. When working, the piezoelectric spray valve descends at the initial position, so that the nozzle of the piezoelectric spray valve contacts the wiping material on the first slot, and then the nozzle moves horizontally forward to the glue spraying position, and glue is sprayed at the glue spraying position to complete the dispensing of the object to be sprayed with glue, and then the piezoelectric spray valve rises to a predetermined height and returns to the initial position, and the above steps are repeated for dispensing.

[0004] The wiping material of the existing nozzle wiping mechanism is soaked with solvent to ensure the wiping effect. However, after a long time of use, the solvent will evaporate, resulting in a decrease in the solvent content of the wiping material, and the wiping effect on the nozzle will be weakened. In addition, long-term use will cause a large amount of residual glue to accumulate on the surface of the wiping material, further weakening the wiping effect on the nozzle. Utility Model Content

[0053] Embodiment 1

[0054] like Figures 1 to 9 As shown, one embodiment of the present application provides a nozzle wet wiping structure, comprising a first box body 110, a first wiping member 120, a first rotating shaft assembly 130 and a first driving member 140;

[0055] The first box body 110 has a first accommodating chamber 111 for containing a solvent;

[0056] The first wiping member 120 has a first wiping surface 121 for wiping the nozzle 500, and the first wiping member 120 is rotatably connected to the first housing 110 via a first rotating shaft assembly 130, so that the first wiping surface 121 is immersed in the solvent of the first accommodating chamber 111;

[0057] The first driving member 140 is connected to the first rotating shaft assembly 130 , and is used to drive the first rotating shaft assembly 130 to rotate, so as to drive the first wiping member 120 to rotate.

[0058] During implementation, the nozzle wet wiping structure 100 provided in the present application is used to wipe the nozzle 500 to remove the glue at the nozzle 500, wherein the nozzle 500 refers to the nozzle 500 of the piezoelectric spray valve of the glue spraying system, and the piezoelectric spray valve sprays glue points on the workpiece 600 through the nozzle 500 to perform corresponding processes on the workpiece 600, which will not be elaborated.

[0059] Optionally, the first wiping member 120 is made of a flexible material with certain adsorption properties, such as sponge, etc., without limitation.

[0060] Optionally, the first box body 110 is a container with an open top, and a first accommodating chamber 111 is provided in the first box body 110. The first accommodating chamber 111 is used to hold a solvent. The first wiping member 120 is connected to the first rotating shaft assembly 130. At the same time, the first rotating shaft assembly 130 is rotatably connected to the first box body 110, so that the first wiping member 120 is at least partially accommodated in the first accommodating chamber 111.

[0061] Optionally, the first wiping member 120 can be designed to be cylindrical, conical, truncated cone, square cone, square cone or other shapes, without limitation. The first wiping member 120 is provided with a first wiping surface 121. For example, taking the first wiping member 120 as a cylinder as an example, the rotation axis of the first rotating shaft assembly 130 coincides with the axis of the cylinder, and the circular side of the cylinder is the first wiping surface 121. Similarly, taking the first wiping member 120 as a cone as an example, the rotation axis of the first rotating shaft assembly 130 coincides with the axis of the cone, and the conical side of the cone is the first wiping surface 121, which will not be described in detail.

[0062] During implementation, the solvent refers to a liquid that can dissolve the glue, such as citrus oil or isoamyl acetate. The corresponding solvent can be selected according to the type of glue, which will not be described in detail.

[0063] In some embodiments, the first driving member 140 can be any one of a motor, a cylinder or a screw assembly, and can be used to drive the first wiping member 120 to rotate without limitation.

[0064] When in use, the first wiping surface 121 is immersed in the solvent of the first accommodating chamber 111. Since the first rotating shaft assembly 130 can rotate relative to the first housing 110, and the first rotating shaft assembly 130 is connected to the first driving member 140, the first driving member 140 drives the first rotating shaft assembly 130 to rotate, so as to drive the first wiping member 120 to rotate relative to the first housing 110, thereby making the first wiping surface 121 cyclically contact with the solvent in the first accommodating chamber 111. In other words, the first wiping member 120 rotates to periodically contact with the solvent, and the first wiping surface 121 can be kept wet, which is equivalent to periodically adding solvent to the first wiping surface 121 to maintain the solvent content of the first wiping surface 121. When the first wiping surface 121 contacts the nozzle 500 for wiping, the wiping effect can be effectively guaranteed, and there is no need to manually add solvent to the first wiping member 120, thereby reducing manpower input.

[0065] Furthermore, even if there is residual glue on the surface of the first wiping member 120 after wiping the nozzle 500, the residual glue can be immersed in the solvent and dissolved by driving the first wiping member 120 to rotate, thereby ensuring the cleanliness of the first wiping surface 121 and further ensuring the wiping effect.

[0066] The nozzle wet wiping structure 100 provided in the present application comprises a first housing 110, a first wiping member 120, a first rotating shaft assembly 130 and a first driving member 140. The first housing 110 has a first accommodating chamber 111 for containing a solvent. The first wiping member 120 is rotatably connected to the first housing 110 through the first rotating shaft assembly 130. The first wiping member 120 has a first wiping surface 121 for wiping the nozzle 500, and the first wiping surface 121 is immersed in the solvent. The first driving member 140 is connected to the first rotating shaft assembly 130. The shaft assembly 130 is connected to drive the first rotating shaft assembly 130 to rotate, so as to drive the first wiping member 120 to rotate, so that the first wiping surface 121 of the first wiping member 120 can be repeatedly immersed in the solvent, thereby reducing the weakening of the wiping effect on the nozzle 500 due to solvent volatilization, and the residual glue remaining after the first wiping surface 121 wipes the nozzle 500 will be dissolved by the solvent in the first accommodating cavity 111, thereby ensuring the surface of the first wiping surface 121 is clean, and further ensuring the wiping effect on the nozzle 500.

[0067] In some optional embodiments, a first liquid inlet 113 and a first liquid outlet 112 are provided on the side of the first box body 110, the first liquid outlet 112 is higher than the lowest point of the first wiping surface 121, the first liquid inlet 113 is level with the first liquid outlet 112, or the first liquid inlet 113 is lower than the first liquid outlet 112.

[0068] During implementation, the first liquid inlet 113 is used to inject solvent into the first containing chamber 111, that is, the first liquid inlet 113 can be connected to the solvent source through a pipeline, and a liquid pump is also provided on the pipeline. The solvent source is pre-stored with solvent, and the solvent is pumped from the solvent source to the first containing chamber 111 by the liquid pump. The amount of solvent in the first containing chamber 111 can be maintained, that is, the liquid level of the solvent in the first containing chamber 111 is kept higher than the lowest point of the first wiping surface 121, so that the solvent can always be in contact with the first wiping surface 121, thereby keeping the first wiping surface 121 moist.

[0069] Optionally, the first liquid outlet 112 can allow the solvent in the first containing cavity 111 to flow out, for example, the first liquid outlet 112 and the above-mentioned solvent source, so as to realize the recycling of the solvent.

[0070] In some embodiments, the first liquid inlet 113 and the first liquid outlet 112 can be arranged at the same height, and the solvent is injected into the first housing 110, and the solvent dissolves the glue and then flows out from the first liquid outlet 112, so as to avoid the situation where the concentration of glue in the solvent is too high and the glue is deposited and adhered to the inner wall of the first receiving chamber 111. Optionally, the first liquid inlet 113 can also be lower than the first liquid outlet 112, so that the solvent flows from low to high in the first receiving chamber 111 to better carry away the dissolved glue.

[0071] In some possible embodiments, the solvent may be injected into the first box body 110 periodically and intermittently, or the solvent may be injected into the first box body 110 continuously. The specific settings may be made according to the actual use environment and requirements. For example, the liquid level of the solvent in the first containing cavity 111 is detected. When the liquid level is lower than the set height, the solvent is injected into the first containing cavity 111, and the solvent that has dissolved the glue is discharged to ensure the efficiency of the solvent in dissolving the glue. There is no limitation.

[0072] In some embodiments, the first shaft assembly 130 includes a hollow shaft 131 , a locking ring 132 , a solid shaft 133 , and a washer 134 ;

[0073] A convex ring 135 is disposed at the first end of the hollow shaft 131, and the second end of the hollow shaft 131 passes through the first wiping member 120 and cooperates with the locking ring 132 to lock the first wiping member 120;

[0074] The first box body 110 is provided with a first axial hole and a second axial hole, and the first end of the solid shaft 133 passes through the first axial hole, the hollow shaft 131 and the second axial hole in sequence and then cooperates with the washer 134, so that the first wiper 120 is rotatably connected to the first box body 110;

[0075] A first end of the solid shaft 133 is connected to the first driving member 140 .

[0076] During implementation, the hollow shaft 131 is in the shape of a hollow tube as a whole, and may be a circular tube, a square tube, or a hollow tube of other shapes, without limitation.

[0077] The first end of the hollow shaft 131 extends radially to form a convex ring 135, that is, the diameter of the convex ring 135 is larger than the diameter of the hollow shaft 131, and the first wiper 120 is provided with a through hole, and the second end of the hollow shaft 131 passes through the through hole and is connected with the locking ring 132. For example, the second end of the hollow shaft 131 is provided with an external thread, and the locking member is provided with an internal thread. The locking member and the second end of the hollow shaft 131 are connected by threaded cooperation. Since the diameter of the locking member is larger than the diameter of the hollow shaft 131, and the diameter of the through hole is the same or substantially the same as the diameter of the hollow shaft 131, the assembly between the hollow shaft 131 and the first wiper 120 can be achieved.

[0078] The solid shaft 133 can be installed in cooperation with the hollow shaft 131 . For example, the hollow shaft 131 can be nested outside the solid shaft 133 , thereby achieving installation cooperation between the solid shaft 133 and the first wiper 120 .

[0079] Optionally, the first housing 110 is provided with a first shaft hole and a second shaft hole, and the first wiper 120 is partially located in the first accommodating cavity 111, wherein the first end of the solid shaft 133 extends from the second shaft hole and is rotatably matched with the second shaft hole, and the second end of the solid shaft 133 passes through the first shaft hole and is rotatably matched with the first shaft hole. The second end of the solid shaft 133 extends radially to form an annular protrusion, and the first end of the solid shaft 133 cooperates with the washer 134 to limit the solid shaft 133 and prevent the solid shaft 133 from slipping out of the first shaft hole or the second shaft hole, and the structure is simple and reliable.

[0080] The first end of the solid shaft 133 extends out of the second axial hole and is connected to the first driving member 140. In some embodiments, the first end of the solid shaft 133 and the first driving member 140 can be connected by thread, bolt, welding, snap or snap connection, etc., without limitation.

[0081] The solid shaft 133 is driven to rotate by the first driving member 140, thereby driving the first wiping member 120 to rotate relative to the first housing 110. The rotation relative to the first housing 110 can make the contact surface of the first wiping member 120 when wiping the nozzle 500 change continuously, thereby increasing the service life of the first wiping member 120. In addition, the first wiping surface 121 is periodically in contact with the solvent, which can keep the first wiping surface 121 moist, thereby preventing the first wiping member 120 from having a weakened wiping effect on the nozzle 500 due to reduced solvent volatilization.

[0082] Furthermore, the first wiping member 120 is truncated cone-shaped and includes a first circular bottom surface 122, a second circular bottom surface 123 and a first wiping surface 121. The diameter of the first circular bottom surface 122 is greater than the diameter of the second circular bottom surface 123. The rotation axis of the first rotating shaft assembly 130 passes through the center of the first circular bottom surface 122 and the second circular bottom surface 123.

[0083] Optionally, the first wiping member 120 is designed to be in the shape of a truncated cone, that is, the truncated cone includes a first circular bottom surface 122, a second circular bottom surface 123 and an inclined side surface, the inclined side surface is the first wiping surface 121, the diameter of the first circular bottom surface 122 of the truncated cone is larger than the diameter of the second circular bottom surface 123 of the truncated cone, that is, the first circular bottom surface 122 of the truncated cone is a large circular bottom surface, and the second circular bottom surface 123 of the truncated cone is a small circular bottom surface, the rotation axis of the first rotating shaft assembly 130 is the center axis of the solid shaft 133, the center of the first circular bottom surface 122 and the center of the second circular bottom surface 123 are both on the center axis of the solid shaft 133, a part of the first wiping surface 121 is always immersed in the solvent, when the solid shaft 133 rotates to drive the first wiping member 120 to rotate, the first wiping surface 121 rotates to be periodically immersed in the solvent. The first wiping member 120 adopts a frustum design, that is, the first wiping surface 121 is an inclined surface, so that the nozzle 500 can be wiped better when the nozzle 500 moves through the first wiping member 120, thereby ensuring a wiping effect.

[0084] In some optional embodiments, the nozzle wet wiping structure 100 provided in the present application further includes a first lifting drive member 150 , and the first lifting drive member 150 is connected to the first box body 110 and is used to drive the first box body 110 to rise and fall.

[0085] The first lifting drive member 150 is provided to drive the first box body 110 to rise and fall, that is, the first wiping member 120 can be lifted and lowered to better contact the nozzle 500 for wiping. The nozzle 500 does not need to perform lifting motion, and the nozzle 500 only performs linear reciprocating motion, thereby reducing the moving stroke of the nozzle 500 and improving efficiency.

[0086] Optionally, the first lifting drive member 150 can be a device that can output power, such as a motor or a cylinder, and can be used to drive the first box body 110 to rise and fall, without limitation.

[0087] Embodiment 2

[0088] In some optional embodiments, the present application also provides a nozzle wiping mechanism, including an empty spray assembly 200, a glue spraying position and the above-mentioned nozzle wet wiping structure 100, and the empty spray assembly 200, the nozzle wet wiping structure 100 and the glue spraying position are arranged in sequence on the moving route of the nozzle 500.

[0089] During implementation, the empty spray assembly 200, the nozzle wet wiping structure 100 and the glue spraying position are arranged in a straight line, so that the nozzle 500 only needs to make a linear motion when moving between the empty spray assembly 200, the nozzle wet wiping structure 100 and the glue spraying position, thereby simplifying the control process of the nozzle 500 and improving efficiency.

[0090] The empty spraying position can collect bad glue dots sprayed by the nozzle 500 and provide the nozzle 500 with periodic empty spraying to prevent the nozzle 500 from being blocked due to long-term non-spraying.

[0091] A workpiece 600 to be processed is placed at the glue spraying position, so that the nozzle 500 can spray glue dots on the workpiece 600 to be processed.

[0092] The nozzle wet wiping structure 100 is as described in the first embodiment, comprising a first housing 110, a first wiping member 120, a first rotating shaft assembly 130 and a first driving member 140, wherein the first housing 110 has a first accommodating chamber 111 for containing a solvent, the first wiping member 120 is rotatably connected to the first housing 110 via the first rotating shaft assembly 130, the first wiping member 120 has a first wiping surface 121 for wiping the nozzle 500, and the first wiping surface 121 is immersed in the solvent, and the first driving member 140 is connected to the first wiping surface 121. A shaft assembly 130 is connected, which is used to drive the first shaft assembly 130 to rotate, so as to drive the first wiping member 120 to rotate, so that the first wiping surface 121 of the first wiping member 120 can be repeatedly immersed in the solvent, thereby reducing the weakening of the wiping effect on the nozzle 500 due to solvent volatilization, and the residual glue remaining after the first wiping surface 121 wipes the nozzle 500 will be dissolved by the solvent in the first accommodating cavity 111, thereby ensuring the surface of the first wiping surface 121 is clean, and further ensuring the wiping effect on the nozzle 500.

[0093] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the structure and implementation principle of the nozzle wiping mechanism described above can refer to the corresponding structure and implementation principle in the aforementioned embodiment 1, and will not be repeated here.

[0094] In some optional embodiments, the air spray assembly 200 includes a second box body 210, and the second box body 210 is provided with a second accommodating chamber 211 for containing a solvent.

[0095] Optionally, the second box 210 is a container with an opening at the top, used to collect bad glue dots sprayed by the nozzle 500. When in use, before the nozzle 500 is started or the first glue dots of a new round are sprayed, the deteriorated glue remaining in the nozzle 500 needs to be discharged in advance, and the bad glue dots formed by the discharged deteriorated glue are sprayed into the second box 210.

[0096] In some optional embodiments, the second box body 210 is provided with a second liquid inlet 212 and a second liquid outlet 213 .

[0097] Optionally, the second accommodating chamber 211 may also contain a solvent, and a second liquid inlet 212 is provided on the second box body 210 to inject the solvent into the second accommodating chamber 211 to dissolve the deteriorated glue discharged from the nozzle 500. At the same time, a second liquid outlet 213 is provided on the second box body 210 to allow the solvent after the glue is dissolved to flow out, thereby preventing the glue from accumulating and precipitating in the second box body 210, causing the glue to adhere to the wall of the second box body 210, and increasing the difficulty of cleaning and maintaining the box body.

[0098] In some embodiments, the air spray assembly 200 can also be designed to include a box bracket (not shown), and the second box 210 can be installed on the box bracket to maintain the height of the second box 210 to facilitate the nozzle 500 to accurately spray glue into the second box 210.

[0099] In some possible embodiments, the empty spray assembly 200 further includes a second lifting drive member 220, which is connected to the second box 210 and is used to drive the second box 210 to rise and fall. By providing the second lifting drive member 220, a lifting function is reserved at the empty spray position, which is convenient for later expansion.

[0100] In some embodiments, the nozzle wiping mechanism provided in the present application further includes a nozzle 500 dry wiping assembly 300 disposed between the dry spray assembly 200 and the nozzle wet wiping structure 100;

[0101] The nozzle 500 dry wipe assembly 300 includes a mounting seat 310, and a second wiper 320 rotatably connected to the mounting seat 310;

[0102] The second wiping member 320 is connected to the first driving member 140 and is configured to rotate under the drive of the first driving member 140 .

[0103] During implementation, the mounting seat 310 is the base of the second wiping member 320, and the second wiping member 320 is arranged on the mounting seat 310. Since the nozzle 500 dry wiping assembly 300 is arranged between the empty spray assembly 200 and the nozzle wet wiping structure 100, when the nozzle 500 completes wet wiping at the nozzle wet wiping structure 100, the nozzle 500 further moves to the nozzle 500 dry wiping assembly 300, and the second wiping member 320 wipes off the residual solvent of the nozzle 500 to avoid the residual solvent from mixing into the glue dots when spraying the glue dots, resulting in a decrease in the quality of the glue dots.

[0104] Optionally, the second wiping member 320 and the first wiping member 120 are both connected to the first driving member 140, and the first driving member 140 outputs power to drive the second wiping member 320 and the first wiping member 120 to rotate, which can reduce the use of the driving device and control the cost. In some possible embodiments, the first driving member 140 can also be composed of two power output devices, for example, the first driving member 140 includes two motors, and the two motors are respectively connected to the second wiping member 320 and the first wiping member 120, so as to respectively control the rotation of the second wiping member 320 and the first wiping member 120, without limitation.

[0105] In addition, the second wiping member 320 can rotate to continuously change the contact position between the second wiping member 320 and the nozzle 500, thereby extending the service life of the second wiping member 320 and allowing the solvent on the wetted wiping surface of the second wiping member 320 sufficient buffer time to evaporate.

[0106] In some embodiments, the nozzle 500 dry erase assembly 300 further includes a second shaft assembly 330;

[0107] The second wiping member 320 is truncated cone-shaped and includes a third circular bottom surface 321, a fourth circular bottom surface 322 and a second wiping surface 323. The third circular bottom surface 321 faces the air spray assembly 200, and the fourth circular bottom surface 322 faces the nozzle wet wiping structure 100. The diameter of the third circular bottom surface 321 is greater than the diameter of the fourth circular bottom surface 322.

[0108] The second rotating shaft assembly 330 passes through the centers of the third circular bottom surface 321 and the fourth circular bottom surface 322 and is rotatably connected to the mounting seat 310 .

[0109] During implementation, the second wiping member 320 and the second rotating shaft assembly 330 may refer to the shape structure and working principle of the first wiping member 120 and the first rotating shaft assembly 130 described above, and no further details are given.

[0110] Optionally, the nozzle 500 dry wipe assembly 300 also includes a third lifting drive member 340, which is connected to the mounting base 310 and is used to drive the mounting base 310 to rise and fall. By driving the second wiping member 320 to rise and fall, the nozzle 500 does not need to perform lifting movement, thereby improving work efficiency.

[0111] In some embodiments, the nozzle wiping mechanism provided in the present application further includes a soaking assembly 400;

[0112] The soaking assembly 400 includes a fourth box body 410 disposed on a side of the empty spray assembly 200 away from the nozzle wet wiping structure 100 , and the fourth box body 410 has a fourth accommodating chamber 411 for containing a solvent.

[0113] The fourth box body 410 is a container with an opening at the top. The fourth containing cavity 411 of the fourth box body 410 is filled with solvent. When the nozzle 500 does not spray glue for a long time, the nozzle 500 can be moved to the immersion component 400 and immersed in the solvent to prevent the glue from solidifying at the nozzle 500 and clogging the nozzle 500, thereby ensuring smooth glue spraying by the nozzle 500.

[0114] Optionally, the soaking assembly 400 further includes a fourth lifting drive member 420, which is connected to the fourth box 410 and is used to drive the fourth box 410 to rise and fall. By providing the fourth lifting drive member 420, the fourth box 410 has a lifting function in the vertical direction, so that the solvent contacts the nozzle 500, and the piezoelectric spray valve does not need to perform lifting motion. The piezoelectric spray valve only needs to perform linear reciprocating motion, thereby improving efficiency.

[0115] Optionally, the immersion component 400 further includes an immersion member (not shown) disposed in the fourth accommodating chamber 411 to absorb the solvent, and a plurality of accommodating grooves are disposed on one side of the immersion member facing the bottom of the fourth accommodating chamber 411 .

[0116] The impregnating member can be a sponge or other objects with adsorption capacity. For example, taking a sponge as an example, the sponge can be divided into two parts, the upper sponge is adapted to the fourth accommodating chamber 411, and the lower sponge is provided with a plurality of accommodating grooves, which can be regarded as accommodating spaces for the solvent. That is to say, the upper sponge can absorb the solvent through the lower sponge to maintain the impregnation state of the upper sponge, making full use of the solvent, and achieving a high solvent utilization rate.

[0117] Optionally, the fourth box body 410 is provided with a third liquid inlet 412 and a third liquid outlet 413 .

[0118] The third liquid inlet 412 and the third liquid outlet 413 are both connected to the fourth accommodating chamber 411, wherein the third liquid inlet 412 is used to inject solvent into the fourth accommodating chamber 411 to maintain the liquid level of the solvent in the first accommodating chamber 111, to prevent the nozzle 500 from being unable to be immersed after the liquid level drops due to solvent volatilization, resulting in residual glue and adhesive tape being precipitated from the nozzle 500 and blocking the nozzle 500. The third liquid outlet 413 is used to discharge the solvent in the first accommodating chamber 111 to discharge the dissolved glue, to avoid the situation where the concentration of glue in the solvent is too high and the glue is deposited and adhered to the inner wall of the first accommodating chamber 111, and to realize the self-cleaning mechanism of the accommodating chamber.

[0119] In some optional embodiments, the fourth box body 410 is further provided with a fifth accommodating chamber 414, and the fifth accommodating chamber 414 is used to load a third wiping piece 415. After the nozzle 500 is soaked, solvent will remain at the nozzle 500. The third wiping piece 415 is used to wipe the residual solvent in the nozzle 500 to avoid the sprayed glue containing solvent affecting the glue effect, thereby ensuring product quality.

[0120] Embodiment 3

[0121] In some optional embodiments, the present application also provides a glue spraying system, including the nozzle wiping mechanism as described above.

[0122] Those skilled in the art can clearly understand that, for the convenience and simplicity of description, the structure and implementation principle of the glue spraying system described above can refer to the corresponding structure and implementation principle in the aforementioned embodiments one and two, and will not be repeated here.

[0123] In implementation, the layout of the functional modules of the nozzle wiping mechanism of the glue spraying system provided by the present application is as follows: Fig. 9 As shown, the normal glue spraying operation logic of the glue spraying system is as follows:

[0124] Step 1.1, the nozzle 500 sprays glue dots at the empty spray position (empty spray assembly 200) for a period of time t1, at which time, the second wiper 320 and the first wiper 120 are both at the B position;

[0125] It should be noted that t1 can be set according to the actual use environment or glue type. For example, t1 can be 5 seconds, 6 seconds or 7 seconds, etc., without limitation.

[0126] Step 1.2, after the dry spraying is completed, the nozzle 500 moves to the dispensing start position;

[0127] In some possible embodiments, to improve efficiency, the nozzle 500 may be accelerated until it reaches v1 and moves to the dispensing start position. Optionally, v1 may be set by the power of the driving device of the nozzle 500 or according to actual use requirements, without limitation.

[0128] Step 1.3, the nozzle 500 moves at a constant speed v1 from the dispensing opening position to the dispensing closing position to complete the glue point spraying;

[0129] The workpiece 600 to be processed is first placed in the glue spraying position before the glue spraying system is started. The glue spraying position includes a glue dispensing start position, a glue dispensing stop position and a stop position.

[0130] Step 1.4, the nozzle 500 starts to decelerate at the dispensing closing position, and the speed drops to 0 at the stop position, and at the same time, the first wiper 120 and the second wiper 320 rise from the B position to the A position;

[0131] Step 1.5, the first wiping member 120 and the second wiping member 320 maintain the position A for a period of time t2 and then return to the position B. During the period of time t2, the nozzle 500 returns from the stop position to the empty spray position, and the first wiping member 120 and the second wiping member 320 complete wiping the nozzle 500 at the position A;

[0132] It should be noted that t2 can be set according to the distance and speed of the nozzle 500 returning from the stop position to the empty spray position, which will not be elaborated herein.

[0133] After the nozzle 500 returns to the empty spraying position, the above steps 1.1 to 1.5 are repeated to complete the next round of glue dot spraying.

[0134] In some optional embodiments, the standby operation logic of the glue spraying system is:

[0135] Step 2.1, record the time t3 that the nozzle 500 is in the empty spraying position. When t3> the specified time, the nozzle 500 moves from the empty spraying position to the soaking position, the fourth box 410 rises from the B position to the A position to soak the nozzle 500, and the glue spraying system enters the standby state;

[0136] The specified time length can be set according to the system operation requirements or the actual use environment. Exemplarily, the specified time length is set to 10 seconds to 40 seconds. For example, the specified time length can be 15 seconds, 20 seconds or 30 seconds, etc., without limitation.

[0137] Step 2.2, the glue spraying system ends standby, the fourth box 410 is lowered to the C position, the nozzle 500 moves to the empty spraying position, and the fourth box 410 is lowered to the B position;

[0138] After the nozzle 500 returns to the empty spraying position, the above steps 1.1 to 1.5 are repeated to execute the normal glue spraying operation logic.

[0139] The nozzle wet wiping structure 100 provided in the present application comprises a first housing 110, a first wiping member 120, a first rotating shaft assembly 130 and a first driving member 140. The first housing 110 has a first accommodating chamber 111 for containing a solvent. The first wiping member 120 is rotatably connected to the first housing 110 through the first rotating shaft assembly 130. The first wiping member 120 has a first wiping surface 121 for wiping the nozzle 500, and the first wiping surface 121 is immersed in the solvent. The first driving member 140 is connected to the first rotating shaft assembly 130. The shaft assembly 130 is connected to drive the first rotating shaft assembly 130 to rotate, so as to drive the first wiping member 120 to rotate, so that the first wiping surface 121 of the first wiping member 120 can be repeatedly immersed in the solvent, thereby reducing the weakening of the wiping effect on the nozzle 500 due to solvent volatilization, and the residual glue remaining after the first wiping surface 121 wipes the nozzle 500 will be dissolved by the solvent in the first accommodating cavity 111, thereby ensuring the surface of the first wiping surface 121 is clean, and further ensuring the wiping effect on the nozzle 500.
