Description

Technical Field

[0001] The invention relates to the field of glue dispensing equipment, and in particular to a glue dispensing device. Background Art

[0002] In the electronics industry such as flat panel displays, glue dispensers are usually used to drip and apply colloids on the surface or inside of products, and after the colloid solidifies, different surfaces can be connected. After working for a long time, the glue dispenser usually needs to wipe off the residual glue on the glue dispenser nozzle to avoid contamination or other effects of the residual glue on subsequent glue dispensing. The traditional way of wiping is to remove the residual glue through a wiping mechanism. First, the glue dispenser valve is fixed, and then the glue dispenser nozzle is moved to the set position through a power mechanism, so that the glue dispenser nozzle fits the wiping mechanism, and the residual glue on the glue dispenser nozzle is dissolved or wiped off through the contact between the solvent and the glue dispenser nozzle. There are currently two main specific wiping methods: one is to fix the dust-free cloth soaked in solvent, and use the power mechanism to drive the dispensing valve to reciprocate, so as to wipe off the glue remaining on the dispensing nozzle. In this wiping method, since the dust-free cloth is fixed, if it is not replaced in time, it is easy to cause secondary pollution to the dispensing nozzle, affecting the wiping effect. At the same time, it is necessary to manually spray alcohol and other solvents on the dust-free cloth, which is inconvenient to operate; the second method is to fix the dispensing nozzle, and the power mechanism drives the wiping mechanism to move in one direction, so as to wipe off the glue remaining on the dispensing nozzle. In this wiping method, when the dust-free cloth passes through the solvent tank, the solvent has poor wettability on the dust-free cloth. At the same time, the dispensing nozzle and the dust-free cloth are in hard contact, which can easily cause scratches on the dispensing nozzle.

[0003] Therefore, how to improve the cleaning effect of the dispensing nozzle of the dispensing machine while effectively protecting the dispensing nozzle has become a problem that needs to be solved urgently. Summary of the invention

[0035] In order to illustrate the dispensing device provided by the present application, the following is a detailed description in conjunction with the accompanying drawings and the text description of the embodiments.

[0036] Reference below Figure 1-Figure 3 The dispensing device 100 according to an embodiment of the present invention is described as follows. Figure 1-Figure 3As shown, the dispensing device 100 includes a base 110, a dispensing mechanism 120, a degumming mechanism 130, a buffer mechanism 140 and a detection mechanism 150. Specifically, the dispensing mechanism 120 includes a valve body 121 and a nozzle 122 and a driving member (not shown in the figure) arranged on the valve body 121. After the conventional dispensing process is completed, the driving member drives the nozzle 122 to move along the vertical direction to a position in contact with the degumming mechanism 130, and the residual glue on the nozzle 122 is removed by the degumming mechanism 130. Specifically, the degumming mechanism 130 includes a solvent box 131, a degumming component 132 and a power component 133. The solvent box 131 is provided with There is a dissolving liquid for dissolving glue, the glue removal component 132 includes a dust-free cloth 1321 and a flexible transmission component 1322, and the power component 133 includes a discharge shaft 1331, a collection shaft 1332, a support shaft 1333 and a power component (not shown in the figure), and the discharge shaft 1331 and the collection shaft 1332 are driven by the power component to rotate, and the support shaft 1333 is a driven component. Further, the dust-free cloth 1321 is sequentially sleeved on the discharge shaft 1331, the support shaft 1333 and the collection shaft 1332, and the dust-free cloth 1321 can contact the nozzle 122 moving up and down to realize the glue removal of the nozzle 122. Further, the flexible transmission component 13 22 is arranged on the supporting shaft 1333 and contacts with the dust-free cloth 1321 and the dissolving liquid respectively. Specifically, the flexible transfer member 1322 transfers the solvent to the dust-free cloth 1321 to improve the degumming effect of the dust-free cloth 1321. Specifically, the buffer mechanism 140 includes an elastic member 141, which is arranged on the base 110 and is used to generate an elastic buffer between the dispensing mechanism 120 and the degumming mechanism 130 to avoid damage to the nozzle 122 or the degumming mechanism 130 caused by hard contact. Specifically, the detection mechanism 150 is arranged on the base 110, and the detection mechanism 150 can be used to detect the nozzle 122 and the dust-free cloth 1321 The contact between the flexible transfer member 1322 and the dissolving liquid, the immersion effect between the flexible transfer member 1322 and the dissolving liquid, the movement state of the buffer mechanism 140, etc.; it can be seen that the dispensing device 100 realizes automatic glue removal by setting the glue removal mechanism 130, thereby improving the glue removal efficiency and glue removal effect. At the same time, a flexible transfer member 1322 is set in the glue removal mechanism 130, and the solvent in the solvent box 131 is transferred to the dust-free cloth 1321 through the flexible transfer member 1322, thereby further improving the dissolution and glue removal effects. At the same time, the flexible transfer member 1322 can play a certain protective role on the nozzle 122, thereby preventing the nozzle 122 from being damaged due to hard contact during the glue removal process.

[0037] It should be noted that the flexible transmission member 1322 can be made of any material that is flexible and has good water absorption performance.

[0038] It should be noted that the support shaft 1333 can be a rotatable support shaft. Further, the support shaft 1333 can be an actively rotating support shaft, or the support shaft 1333 can be a passively rotating support shaft. Of course, in some embodiments, the support shaft 1333 can also be a non-rotatable support shaft. In this case, the support shaft 1333 only serves to fix and support the flexible transmission member 1322.

[0039] It should be noted that when performing a specific glue removal operation, the dust-free cloth 1321 is first made into a roll and put on the discharge shaft 1331. The dust-free cloth 1321 passes around the support shaft 1333 and the solvent box 131 and fits on the receiving shaft 1332. The nozzle 122 is moved to a suitable position through a driving member. During glue removal, the nozzle 122 remains stationary, and the receiving shaft 1332 rotates and drives the dust-free cloth 1321 to move. The moving dust-free cloth 1321 is in continuous contact with the nozzle 122, thereby achieving the purpose of wiping off the residual glue on the nozzle 122. After completing the glue removal operation, the dust-free cloth 1321 is replaced for the next glue removal operation.

[0040] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the flexible transfer member 1322 is at least partially disposed in the solvent box 131, that is, the flexible transfer member 1322 can be in contact with the solvent in the solvent box 131. It can be understood that by partially disposing the flexible transfer member 1322 in the solvent box 131, the flexible transfer member 1322 can soak the solvent in the solvent box 131 and transfer it to the dust-free cloth 1321, which can improve the glue removal effect of the dust-free cloth 1321.

[0041] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the flexible transfer member 1322 is any one of cotton cloth, sponge, rubber or foam. It can be understood that the flexible material among cotton cloth, sponge, rubber or foam can achieve a buffering effect and play a certain protective role on the nozzle 122 to prevent the nozzle 122 from being damaged due to hard contact during the glue removal process. At the same time, the above-mentioned various materials can also transfer the dissolving liquid in the solvent box 131 to the dust-free cloth 1321, so as to further enhance the dissolution and glue removal effects.

[0042] It should be noted that the flexible transmission member 1322 may also be made of other flexible materials with good water absorption properties.

[0043] According to one embodiment of the present invention, Figure 1-Figure 3As shown, the detection mechanism 150 includes a first detection member 151 and a second detection member 152. The first detection member 151 is in contact with the elastic member 141 and is used to detect the movement state of the elastic member 141. The second detection member 152 is arranged on the supporting shaft 1333. The detection mechanism 150 can be used to detect the contact between the nozzle 122 and the dust-free cloth 1321, or to detect the immersion effect between the flexible transfer member 1322 and the dissolving liquid.

[0044] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the first detection member 151 and the second detection member 152 are one of a pressure sensor, a displacement sensor, a laser sensor, a temperature sensor or a humidity sensor. For example, the first detection member 151 is a pressure sensor for detecting the pressure exerted on the elastic member 141 and detecting the movement state of the elastic member 141. For another example, the second detection member 152 is a humidity sensor for detecting the immersion effect of the flexible transfer member 1322 by detecting the humidity of the flexible transfer member 1322.

[0045] It should be noted that in different scenarios, multiple detection components can be added as required to meet actual usage needs. Here, there is no specific limitation on the number of detection components.

[0046] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the elastic member 141 is connected to the glue dispensing mechanism 120, or the elastic member 141 is connected to the glue removal mechanism 130. It can be understood that Figure 1 As shown, the elastic member 141 is connected to the glue dispensing mechanism 120, so that the glue dispensing mechanism 120 can be displaced relative to the glue removal mechanism 130, and the hard contact between the glue dispensing mechanism 120 and the glue removal mechanism 130 is avoided by the buffering of the elastic member 141. The buffering can be achieved by the elastic member 141, or, as shown in FIG. Figure 3 As shown, the elastic member 141 is connected to the glue removal mechanism 130 so that the glue removal mechanism 130 can be displaced relative to the glue dispensing mechanism 120. The elastic member 141 can provide a buffer to avoid hard contact between the glue dispensing mechanism 120 and the glue removal mechanism 130. The elastic member 141 can provide a buffer.

[0047] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the valve body 121 has a positioning member 123 , and the positioning member 123 is used to position the valve body 121 when it moves in the vertical direction, so as to limit the position where the nozzle 122 contacts the dust-free cloth 1321 .

[0048] According to one embodiment of the present invention, Figure 1-Figure 3As shown, the glue removal mechanism 130 is provided with a matching piece 134 which is positioned and matched with the positioning piece 123. It can be understood that by setting the matching piece 134 and the positioning piece 123 to cooperate with each other, the positioning effect is better. Specifically, the positioning piece 123 and the matching piece 134 can be a positioning column and a positioning groove, or the positioning piece 123 and the matching piece 134 can be magnetic suction pieces that can be attracted to each other.

[0049] It should be noted that the positioning member 123 and the matching member 134 may also be in other matching forms, which are not specifically limited here.

[0050] According to one embodiment of the present invention, the dispensing device 100 also includes an automatic feeding mechanism (not shown in the figure), and the discharge port of the automatic feeding mechanism is connected to the solvent box 131. It can be understood that by setting up the automatic feeding mechanism, when the detection mechanism 150 detects that the dissolving liquid in the solvent box 131 is reduced, the corresponding dissolving liquid can be replenished in time, thereby maintaining a good glue removal effect.

[0051] According to one embodiment of the present invention, a plurality of chambers (not shown in the figure) are arranged inside the solvent box 131 of the dispensing device 100. Furthermore, the plurality of chambers are not interconnected. It can be understood that by providing a plurality of chambers that are not interconnected on the inside of the solvent box 131, a plurality of solvents can be stored, and then the material of the corresponding dissolving liquid can be adjusted according to the type of glue remaining on the nozzle 122 to achieve a better glue removal effect.

[0052] The above dispensing device provided in the present application is a preferred embodiment and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field should know that various improvements or replacements can be made without departing from the concept of the present application. All improvements or replacements should be within the scope of protection of the present application, that is, the scope of protection of the present application should be based on the claims.
