DETAILED DESCRIPTION

[0015] In order to make the above-mentioned purpose, features and advantages of the double-component glue dispensing device more apparent, specific embodiments of the double-component glue dispensing device are described in detail below with reference to the drawings.

[0016] As Figure 1As shown, the two-component dispensing device provided in the embodiments of this application includes a support 1, a glue supply mechanism 2 disposed on the support 1, a mixing cylinder 3 disposed on the support 1, a screw valve mechanism 4 disposed on the support 1 for pressing the A glue and B glue in the glue supply mechanism 2 into the mixing cylinder 3, a glue dispensing component 5 communicating with the lower end of the mixing cylinder 3, a condensation component 6 disposed on the support 1 for cooling the glue dispensing component 5, and a water collection box 7 disposed on the support 1. The water collection box 7 is provided with a water collection trough and a clearance hole communicating with the water collection trough. The glue dispensing component 5 dispenses glue through the clearance hole. The glue dispensing component 5 is sealed to the clearance hole. The water collection box 7 is provided with a water suction channel communicating with the water collection trough.

[0017] In actual use, adhesive A and adhesive B are supplied to the mixing cylinder 3 via the adhesive supply mechanism 2. The flow rate of adhesive A and adhesive B in the adhesive supply mechanism 2 is controlled by the screw valve mechanism 4. After entering the mixing cylinder 3, adhesive A and adhesive B are mixed to form a mixed adhesive, which then enters the dispensing assembly 5 for dripping. Heat is generated during the mixing process of adhesive A and adhesive B. The dispensing assembly 5 is cooled by the condensing assembly 6 to prevent the mixed adhesive from reacting. Since the condensing assembly 6 produces condensate after condensation, the condensate is collected by the water collection box 7 and then sucked away by an external vacuum generator.

[0018] In the above design, by setting up the water collection box 7, the condensate of the condensation component 6 can be effectively collected, preventing the condensate generated during the dispensing process from dripping onto the electronic products undergoing the dispensing process, and effectively preventing the condensate from damaging the electronic products during the dispensing process.

[0019] Specifically, a sealing ring is provided between the lower end face of the condensation component 6 and the upper end face of the water collection box 7.

[0020] In the above design, the sealing between the lower end face of the condenser assembly 6 and the water collection box 7 can be effectively guaranteed by setting a sealant.

[0021] Specifically: such as Figure 1 As shown, the glue supply mechanism 2 includes a glue supply cylinder 21, a glue conveying block 22 mounted on the support 1, and a glue extrusion assembly mounted on the support. The glue supply cylinder 21 has a first chamber for holding glue A and a second chamber for holding glue B. The glue conveying block 22 has a first flow channel and a second flow channel. The two ends of the first flow channel are respectively connected to the first chamber and the mixing cylinder 3, and the two ends of the second flow channel are respectively connected to the second chamber and the mixing cylinder 3. The glue extrusion assembly includes a first push rod 23 slidably connected to the first chamber, a second push rod 24 slidably connected to the second chamber, a first rodless cylinder 25 mounted on the support 1 for driving the first push rod 23 to rise and fall, and a second rodless cylinder 26 for driving the second push rod 24 to rise and fall.

[0022] In actual use, the first rodless cylinder 25 drives the first push rod 23 to descend, allowing adhesive A to enter the mixing cylinder 3 from the first chamber along the first flow channel. The second rodless cylinder 26 drives the second push rod 24 to descend, allowing adhesive B to enter the mixing cylinder 3 from the second chamber along the second flow channel. During the flow of adhesive A and adhesive B along the first and second flow channels respectively, the flow rates of adhesive A and adhesive B are controlled by the screw valve mechanism 4.

[0023] In the above design, the structure of the glue supply mechanism 2 facilitates the rapid flow of glue A and glue B into the mixing cylinder 3 for mixing.

[0024] Specifically: such as Figure 1 As shown, the screw valve mechanism 4 includes a first screw valve 41 and a second screw valve 42. The first screw valve 41 is used to control the adhesive pressure in the first flow channel, and the second screw valve 42 is used to control the adhesive pressure in the second flow channel.

[0025] In actual use, the flow rate and volume of adhesive A in channel 1 and adhesive B in channel 2 cannot be kept stable on their own. The adhesive pressure in channels 1 and 2 is controlled by screw valve 41 and screw valve 42 respectively to stabilize the flow rate and volume of adhesive A in channel 1 and adhesive B in channel 2.

[0026] The above design facilitates the stability of the flow rates of adhesive A and adhesive B.

[0027] Specifically: such as Figure 2 As shown, the dispensing assembly 5 includes a dispensing valve 51, a first tube 52 connected to the mixing cylinder 3, a dispensing funnel 53 fixedly installed on the clearance hole, a needle 54 installed on the dispensing funnel 53, and a first cylinder 55 fixedly installed on the bracket 1 for driving the valve core of the dispensing valve 51 to switch directions. One of the openings of the dispensing valve 51 is connected to the lower end of the first tube 52, and the other opening of the dispensing valve 51 is connected to the upper end of the needle 54.

[0028] In actual use, when dispensing is required, the valve core of dispensing valve 51 is reversed by cylinder 55, opening the passage. The mixed adhesive then enters tube 52 from mixing cylinder 3, passes through dispensing valve 51, and enters needle 54 for dispensing. When dispensing is not required, the valve core of dispensing valve 51 is reversed by cylinder 55, closing the passage.

[0029] In the above design, the structural design and specific implementation of the dispensing assembly facilitate rapid dispensing.

[0030] It should be understood that the above are only specific embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
