Description

Technical Field

[0001] The utility model belongs to the technical field of electronic manufacturing, and in particular relates to a gluing device for a halogen-free copper-clad plate. Background Art

[0002] In the manufacturing process of electronic products, copper clad laminate is one of the basic raw materials, and its quality directly affects the performance and reliability of the final product. In the traditional copper clad laminate processing process, the gluing operation is a crucial step, which involves evenly applying glue on the surface of the copper clad laminate to ensure that the copper clad laminate has good adhesion and protection in subsequent lamination or processing. However, there are many problems with the existing gluing technology, such as uneven application of glue and improper handling of excess glue.

[0003] On the one hand, traditional glue coating devices usually use a single glue coating mechanism, which limits the uniform distribution of glue and processing efficiency, especially when layered glue coating is required. In addition, excessive use of glue not only increases material costs, but may also affect the surface quality of the copper clad laminate due to glue accumulation. On the other hand, the recycling of excess glue is often inefficient, which not only causes a waste of resources, but also causes potential pollution to the environment.

[0004] In the prior art, the glue spraying system and glue recovery system are often operated independently, and the adjustment and maintenance of the overall equipment are relatively complicated, which increases the workload of the operators. During the glue spraying process, common problems include glue splashing and dripping, which will affect the uniformity of the glue coating of the copper clad laminate and may cause pollution to the working area environment. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a halogen-free copper clad laminate gluing device, which can achieve efficient and uniform application of glue and optimize the use and recovery process of the glue.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A gluing device for a halogen-free copper-clad laminate comprises a conveyor belt, a gluing mechanism is arranged above the conveyor belt, and the number of the gluing mechanisms is set to two;

[0008] The glue coating mechanism comprises a driving roller, one end of which is provided with a first motor that drives the driving roller to rotate;

[0009] A glue spraying hose is provided on one side of the conveyor belt, and the glue spraying hose is located between the driving roller and the driven roller;

[0010] Both ends of the glue coating mechanism are provided with glue collecting mechanisms;

[0011] A scraper assembly is arranged above the glue coating mechanism, and the scraper assembly is used to scrape off the excess glue on the driving roller.

[0012] Furthermore, the glue collecting mechanism comprises a collecting bin located at both ends of the driving roller, and an oblique flow member is provided below the collecting bin;

[0013] The diagonal flow member is arranged obliquely.

[0014] Furthermore, the longitudinal section of the collecting bin is set to an inverted trapezoid, and a first discharge hole is opened through the bottom of the collecting bin. A guide plate is fixedly connected to the bottom of the collecting bin, and the guide plate is inclined, and one end of the guide plate extends into the oblique flow member.

[0015] Furthermore, both sides of the top of the collection bin are fixedly connected with connecting plates, and the upper end surface of the connecting plate is penetrated with connecting holes at equal intervals along the length direction thereof.

[0016] Furthermore, a second discharge hole is formed through the bottom of one end of the oblique flow member.

[0017] Furthermore, the scraper assembly includes a positioning shaft, and one end of the positioning shaft is provided with a second motor for driving the positioning shaft to adjust its angle;

[0018] A linkage plate is connected to the outer side of the positioning shaft, and a scraper strip is connected to the inner side of one end of the linkage plate.

[0019] Furthermore, a clamping plate is provided on the outer side of the scraper strip, and the clamping plate and the linkage plate are connected by bolts.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] First, by adopting the dual glue coating mechanism configuration, the device can flexibly adjust the glue coating operation according to the processing requirements of the copper clad laminate, whether working independently or synchronously, it can significantly improve the efficiency and quality of glue coating. This design allows more copper clad laminates to be processed in a shorter time, while ensuring that the glue is evenly distributed on each board, which directly improves the quality of the product and the continuity of production.

[0022] Secondly, through the integrated glue recovery mechanism, especially the design of the glue collection mechanism and the diagonal flow piece, the excess glue can be effectively collected and reused or safely disposed of. This not only reduces the waste of glue, but also reduces the environmental burden. The guide plate and inverted trapezoidal collection bin in the design further optimize the collection and flow control of glue, prevent glue splashing and leakage, and keep the work area clean and safe.

[0023] Finally, the adjustable design of the scraper assembly (adjusting the angle and pressure of the positioning shaft and scraper bar through the second motor) provides more precise control of the glue thickness for the copper clad laminate. This ensures the uniformity and appropriate thickness of the glue layer on the surface of the copper clad laminate, thereby meeting the requirements of adhesion and protection for different applications. Through the optimization of the scraper assembly, the device can not only improve the processing quality of the copper clad laminate, but also simplify maintenance work and improve operational efficiency.

[0039] See also Figure 2 The glue collecting mechanism 4 includes a collecting bin 41 located at both ends of the driving roller 21, and an oblique flow member 44 is arranged below the collecting bin 41; the oblique flow member 44 is inclined so that the recovered glue liquid can flow to the designated processing system or storage container conveniently.

[0040] See also Figure 2 The longitudinal section of the collecting bin 41 is set to an inverted trapezoid, and a first discharge hole 411 is opened through the bottom of the collecting bin 41.

[0045] The working principle of the utility model is:

[0046] When the copper clad laminate is glued, the glue is transported between the driving roller 21 and the driven roller 22 through the glue spraying tube 3. The driving roller 21 and the driven roller 22 are driven to rotate by the first motor 23, so that the glue is evenly applied to the driving roller 21 and the driven roller 22. In the process of evenly applying the glue, the excess glue is discharged from both ends of the driving roller 21 and the driven roller 22 and drips into the collecting bin 41. The glue that falls into the collecting bin 41 enters the oblique flow member 44 through the first discharge hole 411. By providing a guide plate 43 between the collecting bin 41 and the oblique flow member 44, the glue is prevented from splashing when it falls into the oblique flow member 44.

[0047] When the gluing operation is completed, the second motor 55 drives the positioning shaft 51 to turn over, so that the scraper 53 is attached to the driving roller 21, and the glue on the positioning shaft 51 is scraped off by the scraper 53;

[0048] By setting the number of the gluing mechanisms 2 to two, the copper clad laminate can be glued in layers according to processing requirements, thereby improving the gluing quality of the copper clad laminate.
