[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0028] This embodiment provides a wide-width gluing mechanism to solve the technical problems that the inner wall of the current glue dispensing head is cylindrical, the cross section of the glue flowing out is circular, the gluing width is small, and the same board needs to be coated with multiple layers to ensure the gluing coverage, which affects the production rhythm of gluing and has high investment and cost. The wide-width gluing mechanism of this embodiment realizes a wider range of wide-width gluing of the gluing head, and the glue can be evenly coated in a large area, thereby improving the product yield, meeting actual practical needs, reducing the amount of glue used, and reducing the cost of use.

[0029] Reference Figure 1-Figure 3 The large-width gluing mechanism of this embodiment includes a gluing head, a mounting part and a mixing tube 5.

[0030] The glue coating head includes two relatively arranged glue coating plates 1, and glue flow grooves are provided on opposite sides of the two glue coating plates 1. Glue outlet grooves connected to the glue flow grooves are provided on the bottoms of the opposite sides of the two adjustment plates along their length directions. A protrusion is integrally formed around its glue flow groove on one of the glue coating plates 1, and a groove is provided around its glue flow groove on the other glue coating plate 1. The protrusion is snapped into the groove, so that the glue flow grooves of the two glue coating plates 1 cooperate to form a glue cavity 2, and the two glue outlet grooves cooperate to form a strip-shaped glue outlet 3. After the glue enters the glue cavity 2, it flows out from the strip-shaped glue outlet 3. The cross-section of the glue that flows out is long and strip-shaped, and the glue coating width is large. The glue outlet speed is fast and can cover a larger area. The length of the glue coating track is reduced for the same area, which improves the production rhythm and enables the glue coating head to coat a wider range of glue. The glue can be evenly coated on a large area, thereby improving the product yield rate, meeting actual practical needs, reducing the amount of glue used, and reducing the cost of use. In this embodiment, combined with Figure 4, the depth of the glue outlet groove is less than the depth of the glue flow groove, so that the width of the strip glue outlet 3 is less than the width of the glue chamber 2, so that the internal wide outlet of the glue coating head is narrow, which meets the pressure of glue coating, allowing the glue to fill the strip glue outlet 3 and achieve uniform coating. At the same time, in this embodiment, three diverter blocks 4 are arranged in the glue flow groove of one of the glue coating plates 1 along its length direction, and a diverter channel is formed between two adjacent diverter blocks 4, so as to divert the glue and make the glue evenly distributed in the strip glue outlet 3 to meet the uniform coating. In order to improve the diversion effect, in this embodiment, the width of the diverter block 4 gradually decreases from the end away from the strip glue outlet 3 to the end close to the strip glue outlet 3. In this embodiment, the top of the opposite side of the two glue coating plates 1 is provided with a semicircular groove connected to its glue flow groove, and the two semicircular grooves are spliced ​​to form an assembly hole. In this embodiment, the two glue coating plates 1 are formed by polytetrafluoroethylene machining and can be reused after cleaning.

[0031] The mounting member includes a fixed seat 6 and a rotating seat 7 which are arranged opposite to each other. The fixed seat 6 and the rotating seat 7 are provided with mounting grooves on both sides and the two mounting grooves cooperate to form a mounting cavity. Compressed foam 15 is pasted in the two mounting grooves, and two rubber-coated plates 1 are respectively clamped in the two mounting grooves. One end of the fixed seat 6 is rotatably connected with one end of the rotating seat 7, and the other end of the fixed seat 6 is provided with a clamping groove 8 extending from its side to its inside. The rotating seat 7 is rotatably connected with a rotating shaft 9 on one side corresponding to the clamping groove 8, and a clamping column 10 which is detachably clamped in the clamping groove 8 is connected to the rotating shaft 9, and a locking knob 11 is connected to the end of the clamping column 10 away from the rotating shaft 9. When installing the glue coating head, first clamp the two glue coating plates 1 together, then clamp one of the adjustment plates into the mounting groove of the fixed seat 6, and then rotate the rotating seat 7 to cover the other glue coating plate 1. The clamping column 10 is driven to rotate by the locking knob 11 so that the clamping column 10 is clamped into the clamping groove 8, so that the glue coating head is clamped between the fixed seat 6 and the rotating seat 7. The compression foam 15 ensures the clamping force of the two glue coating plates 1 after being fitted together, and does not deform under the action of the glue pressure. In this embodiment, the top of the fixed seat 6 and the rotating seat 7 are both provided with a semicircular avoidance groove coaxial with the assembly hole, and the two semicircular avoidance grooves cooperate to form an avoidance groove. A clamping seat 12 is fixed to the top of the fixed seat 6, and the clamping seat 12 runs through a clamping hole coaxial with the assembly hole.

[0032] Since the glue will solidify over time, the above structural setting allows the glue coating head to be removed from the mounting part, making it convenient to disassemble and clean the glue coating head. The glue coating head is a processed part and can be reused after cleaning, reducing the cost of replacing the glue coating plate 1 per shift.

[0033] The bottom of the mixing tube 5 is clamped in the clamping hole and connected to the assembly hole through the avoidance groove, so that the mixing tube 5 is connected with the glue chamber 2 to transport glue into the glue chamber 2. A section of the mixing tube 5 located in the assembly hole is sleeved with an O-ring 13 for sealing. A protective sleeve 14 is sleeved outside the mixing tube 5.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
