Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

In the assembly process of the workpiece, a glue coating device is generally used, and glue is coated at a specified position through the glue coating device, for example, so that the fixing, heat conduction and other effects of the workpiece are realized. The glue outlets of the gluing devices in the related art are all round hole type glue outlets, namely, finally-coated glue is columnar, and a wider adhesive tape can be coated only by multiple times of coating, so that the gluing efficiency is low. Based on this, this embodiment provides a rubber coating device, can improve rubber coating efficiency.

The gluing device is described in detail below with specific examples:

referring to fig. 1 to 10, the present embodiment provides a glue spreading device, which includes a glue spreading head body 1, the glue spreading head body 1 has a pressure stabilizing cavity 10, one end of the pressure stabilizing cavity 10 has a glue inlet 101, and the other end of the pressure stabilizing cavity 10 has a glue outlet 102. It can be understood that the glue enters the pressure stabilizing cavity 10 from the glue inlet 101, flows along the pressure stabilizing cavity 10 toward one end of the glue outlet 102, and is finally coated out from the glue outlet 102.

The colloid can be heat-conducting colloid or non-heat-conducting colloid. The colloid can be single-component colloid, double-component colloid or multi-component colloid. The present disclosure is not particularly limited to this, and may be set according to actual needs.

In a specific implementation, as shown in fig. 1 and 13, the glue applying device may include a mixing tube adapter 2, and the glue applying device may be specifically communicated with the mixing tube through the mixing tube adapter 2, wherein the mixing tube contains a colloid, for example, when the colloid is a two-component colloid or a multi-component colloid, the colloid is mixed in the mixing tube. Specifically, the mixing tube adapter 2 has an inlet 21 and an outlet 22, the inlet 21 is communicated with the mixing tube, and the outlet 22 is communicated with the glue inlet 101, that is, the glue in the mixing tube enters the pressure stabilizing cavity 10 through the mixing tube adapter 2. Mixing tube crossover sub 2 has and stretches into section 20, stretches into section 20 and can stretch into to rubber coating head body 1 in, the lateral wall that stretches into section 20 is provided with the external screw thread, and rubber coating head body 1's corresponding position has the internal thread, realizes mixing tube crossover sub 2 and rubber coating head body 1's being connected through external screw thread and internal screw thread cooperation.

Referring to fig. 1, in this embodiment, the glue outlet 102 is specifically a strip-shaped glue outlet, and the glue outlet 102 is set as the strip-shaped glue outlet, so that the glue strip directly coated from the glue outlet 102 is a strip-shaped glue strip, that is, a wide glue strip, thereby ensuring the width of the coated glue strip, avoiding multiple coating, and improving the coating efficiency.

Generally, the adhesive tape to be applied needs to be attached to a workpiece after the adhesive is applied, if the surface of the adhesive tape applied from the adhesive outlet 102 is flat, an escape route of air is easily closed in the pressing process, so that air bubbles are easily mixed in the adhesive tape, and the bonding effect is affected, for example, when the adhesive is a heat-conducting adhesive, the mixing of the air bubbles can affect the heat-conducting effect. Based on this, in the present embodiment, the width a of the glue outlet 102 is greater than the width b of the glue inlet 101. As shown in fig. 1, 6 and 7, since the width a of the glue outlet 102 is greater than the width b of the glue inlet 101, when viewed from the whole, in the process that the glue passes through the pressure stabilizing cavity 10 from the glue inlet 101 and is finally coated from the glue outlet 102, the pressure of the glue is attenuated from the center to the periphery, so that the thickness of the wide glue strip finally extruded from the glue outlet 102 is attenuated to both sides to a certain extent from the center, i.e. to form a smaller radian, and when the wide glue strip is attached to a workpiece for installation, air in the glue pressing process can escape from both sides of the wide glue strip, thereby avoiding the occurrence of air bubbles mixed in the wide glue strip after the glue pressing is completed, and avoiding the influence of the air bubbles on the bonding effect or the heat conduction effect.

As shown in fig. 7 and 8, the width b of the glue inlet 101 refers to the lateral width of the glue inlet 101 in the figure. In the present embodiment, the cross section of the glue inlet 101 is circular, and the width b of the glue inlet 101 refers to the diameter of the glue inlet 101. In other implementations, the cross section of the glue inlet 101 may also have other shapes, and the width of the glue inlet 101 is the size of the glue inlet 101 in the transverse direction. Referring to fig. 5 and 7, the width a of the glue outlet 102 refers to the lateral width of the glue outlet 102 in the figure. That is, the lateral width of the glue outlet 102 is larger than the lateral width of the glue inlet 101.

According to the gluing device provided by the embodiment, the glue outlet 102 is arranged to be the strip-shaped glue outlet 102, so that the glue outlet 102 directly coats a strip-shaped glue strip, namely a wide glue strip, multiple coating can be avoided, and the coating efficiency is improved; meanwhile, because the width of the glue outlet 102 is greater than that of the glue inlet 101, in the process that the glue flows from the glue inlet 101 to the glue outlet 102 through the pressure stabilizing cavity 10, the pressure of the glue is attenuated from the center to the periphery, so that the thickness of the wide glue strip extruded from the glue outlet 102 is attenuated to a certain degree from the center to two sides, namely, a smaller radian is formed, when the wide glue strip is attached to a workpiece to be installed, air in the glue pressing process can escape from two sides of the wide glue strip, the situation that air bubbles are mixed in the wide glue strip after the glue pressing is finished is avoided, and the bonding effect or the heat conduction effect and the like are prevented from being influenced by the mixed air bubbles.

With continued reference to fig. 1, 6 and 7, it is preferable that the width of the pressure stabilizing cavity 10 gradually increases and then gradually decreases along the direction from the glue inlet 101 to the glue outlet 102. Note that the width of the cavity 10 here is the transverse dimension L of the cavity 10 in fig. 7.

It can be understood that a section of the pressure stabilizing cavity 10 close to the glue inlet 101 is an expanding section, and a section of the pressure stabilizing cavity 10 close to the glue outlet 102 is a closing section. The colloid enters the pressure stabilizing cavity 10 from the colloid inlet 101, the pressure of the colloid is gradually reduced from top to bottom, and the colloid gradually attenuates from the center to the pressure around when passing through the section as the width of the pressure stabilizing cavity 10 is gradually increased. Because the width of the pressure stabilizing cavity 10 is further gradually reduced, namely the closing-in section can realize the reinforcement of the glue injection pressure of the outer ring, and the reinforcement force is conducted from outside to inside, the reinforcement pressure is gradually attenuated from outside to inside, and the compensation is just formed with the glue injection pressure attenuated from the center to the periphery, so that the thickness of the extruded wide glue strip is more uniform. In addition, because the width of the glue outlet 102 is larger than that of the glue inlet 101, the overall pressure of the glue is attenuated from the center to the periphery, so that the thickness of the extruded wide glue strip is slightly reduced from the center to the two sides, namely, a small radian is formed, and gas can be discharged when the wide glue strip is attached to a workpiece. That is to say, with the setting of steady voltage chamber 10 as above, not only can guarantee the thickness homogeneity of broad width adhesive tape, guaranteed simultaneously again that the smooth and easy escape of air when broad width adhesive tape and work piece laminate, avoid the condition that the bubble sneaks into to appear.

Specifically, the glue inlet 101 and the glue outlet 102 can be located on the central axis of the pressure stabilizing cavity 10, so that the flow process of the glue can be smoother, and the uniformity of the wide glue strip can be further improved.

Wherein, can make the area of advancing gluey mouth 101 be greater than or equal to the area of going out gluey mouth 102 to guarantee the pressure demand of going out gluey mouth 102, guarantee rubber coating's stability, make to paint and change and control. Preferably, the area of the glue inlet 101 is equal to the area of the glue outlet 102. Referring to fig. 4 and 5, it should be noted that the area herein specifically refers to the cross-sectional area of the glue inlet 101 and the glue outlet 102.

In this embodiment, the gluing head body 1 specifically includes a first housing 11 and a second housing 12 connected to the first housing 11, and the first housing 11 and the second housing 12 together enclose to form the pressure stabilizing cavity 10. Namely, the gluing head body 1 is composed of two parts of shells, so that the gluing head body 1 is more convenient to manufacture. In the specific assembly, the first housing 11 and the second housing 12 are butted and then fixed together.

Specifically, the first housing 11 and the second housing 12 may be detachably connected. This facilitates assembly and maintenance. For example, when one of the first casing 11 and the second casing 12 is damaged, the first casing and the second casing are detached from each other, and only the damaged casing needs to be replaced, so that the scrapping of the whole gluing head body is avoided, and the maintenance cost is saved.

In the present embodiment, the first housing 11 has a first mounting hole 110, and the second housing 12 has a second mounting hole 120 at a position corresponding to the first mounting hole 110, when assembling, the first mounting hole 110 and the second mounting hole 120 are aligned, and the first housing 11 and the second housing 12 are connected by screws inserted into the first mounting hole 110 and the second mounting hole 120. Specifically, a plurality of first mounting holes 110 and second mounting holes 120 may be provided to improve connection stability. Of course, the first housing 11 and the second housing 12 may be connected by other methods such as snap-fitting.

Wherein, a maintenance opening 103 may be further opened at an edge of the joint of the first housing 11 and the second housing 12 to facilitate the separation of the first housing 11 and the second housing 12. For example, the maintenance opening 103 is formed in an edge of a surface of the first housing 11 which is in contact with the second housing 12.

With continued reference to fig. 9 and 10, in the present embodiment, the plenum 10 is provided specifically on the first housing 11, and the side of the second housing 12 facing the plenum 10 has an extended projection 121. When the first housing 11 and the second housing 12 are matched, the extending convex part 121 extends into the pressure stabilizing cavity 10, and a space for the glue to flow is formed between the extending convex part and the pressure stabilizing cavity 10. The end of the extending protrusion 121 away from the glue inlet 101 and the first housing 11 jointly define the glue outlet 102. The extending convex part 121 is arranged, so that the extending convex part 121 is matched with the pressure stabilizing cavity 10, and the colloid is guided.

Specifically, one surface of the extending convex portion 121 facing the surge chamber 10 is formed as a guide inclined surface 122, and the guide inclined surface 122 is inclined toward the inner cavity direction close to the surge chamber 10 in the direction from the glue inlet 101 to the glue outlet 102. That is, the guiding inclined plane 122 gradually inclines downwards in the direction from the glue inlet 101 to the glue outlet 102, i.e. the final strip-shaped glue outlet is gradually formed from top to bottom, so as to mold the wide glue strip.

In this embodiment, the gluing head body 1 is further provided with a heating structure 13, and the heating structure 13 is used for heating the glue entering from the glue inlet 101, so that the temperature of the glue meets the specific requirements.

The heating structure 13 specifically comprises a heating element (not shown in the figure) arranged outside the gluing head body 1, and the heat emitted by the heating element is transferred to the glue body through the gluing head body 1, so that the glue body is heated. It can be understood that, this moment, can make rubber coating head body 1 have thermal conductivity, also can set up the heat-conducting piece in rubber coating head body 1, and the heat that the piece that generates heat sent transmits to the colloid through the heat-conducting piece. The temperature of the colloid can be controlled by controlling the heating temperature of the heating element. The heating element can be an electric heating tube or an electric heating wire, or a heating tube with heating liquid, and can be set according to actual requirements.

Referring to fig. 1 to 5, 11 and 12, the heating structure 13 specifically includes a plate 131, the plate 131 is disposed outside the gluing head body 1, a receiving groove 132 is disposed on a surface of the plate 131 facing the gluing head body 1, and the heating element is disposed in the receiving groove 132.
