DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] A side frame glue dispensing device for igbt assembly, such as Figure 1-Figure 5 , including a workbench 1, an inverted U-shaped mounting plate 2, a first electric slide rail 4, a second electric slide rail 5, a third electric slide rail 51, a glue storage tank 6, a liquid pump 8, a glue delivery hose 9, a glue dispensing head 10, a heating ring 11, a support table 13, a support plate 14, a rotating clamping plate 15, a cylinder 16, a rotating sleeve 17, a worm 18, a motor 19, a fixed shell 20 and a worm gear 21. The front side of the top of the workbench 1 is symmetrically installed with an inverted U-shaped mounting plate 2, and the top of the inverted U-shaped mounting plate 2 is fixedly connected with the first electric slide rail 4, and the two third electric slide rails are fixedly connected. A second electric slide rail 5 is connected between the sliders of an electric slide rail 4, a third electric slide rail 51 is fixedly installed on the slider of the second electric slide rail 5, a glue dispensing head 10 is fixedly connected to the slider of the third electric slide rail 51, a heating ring 11 is embedded on the glue dispensing head 10, a glue storage tank 6 is connected to the top rear side of the workbench 1, a liquid pump 8 is fixedly installed at the bottom of the glue storage tank 6, the liquid pump 8 is connected to the glue dispensing head 10 through a glue delivery pipe 9, and the glue delivery pipe 9 is a hose that can be stretched and deformed to avoid hindering the movement of the glue dispensing head 10. A support platform 13 is installed on the front side of the top of the workbench 1. The support platform 13 is located between the two inverted U-shaped mounting plates 2. The top of the support platform 13 is fixedly connected to two left and right support plates 14. The top of the right support plate 14 is connected to a cylinder 16. The telescopic rod of the cylinder 16 and the left support plate 14 are both rotatably connected with a rotating clamping plate 15. The rotating clamping plate 15 is made of rubber. The rotating clamping plate 15 made of rubber is soft and can avoid pinching the side frame. At the same time, it can increase the friction with the side frame, so that the side frame can be driven to rotate stably and smoothly. A fixed shell 20 is fixedly installed on the telescopic rod of the cylinder 16, and the fixed shell 20 is located to the right of the right rotating splint 15. The right end face of the rotating splint 15 connected to the telescopic rod of the cylinder 16 is fixedly connected to a rotating sleeve 17. The right end of the rotating sleeve 17 passes through the left end face of the fixed shell 20. The right end of the rotating sleeve 17 is fixedly connected to a worm gear 21. The worm gear 21 is rotatably connected to the telescopic rod of the cylinder 16. A motor 19 is installed on the lower side of the fixed shell 20. A worm 18 is connected to the output shaft of the motor 19, and the worm 18 is meshed with the worm gear 21.

[0023] When the device is in operation, the telescopic rod of the control cylinder 16 is extended to drive the rotating clamping plate 15 on it to move to the left, and the side frame is clamped by the rotating clamping plates 15 on both sides, and the control motor 19 drives the worm 18 to rotate, and the worm 18 drives the worm wheel 21 to rotate, and the rotation of the worm wheel 21 drives the rotating clamping plate 15 on the right side to rotate through the rotating sleeve 17, and the rotation of the rotating clamping plate 15 drives the side frame to rotate to a suitable angle, and the first electric slide rail 4 is controlled to work to drive the second electric slide rail 5 to move forward, so that the third electric slide rail 51 drives the dispensing head 10 to move forward to the top of the side frame, and then the control The third electric slide 51 works to adjust the glue dispensing head 10 to a suitable glue dispensing height, and then controls the liquid pump 8 to work. The liquid pump 8 extracts glue from the glue storage tank 6 and transports it to the glue dispensing head 10 through the glue delivery pipe 9. The heating ring 11 is controlled to work to heat the glue in the glue dispensing head 10 to prevent the glue from solidifying and clogging the glue dispensing head 10. When the glue dispensing head 10 is dispensing glue, the first electric slide 4 is controlled to work so that the glue dispensing head 10 moves horizontally along the side frame to achieve uniform glue dispensing. After the glue dispensing on one side of the side frame is completed, the above operation is repeated to rotate the side frame to change the surface, so as to achieve comprehensive glue dispensing on the side frame. After the side frame is glued, the telescopic rod of the control cylinder 16 is retracted to drive the rotating clamp 15 on it to move to the right to release the clamping of the side frame. At the same time, the side frame is manually limited to prevent the side frame from falling and contacting the support platform 13 to scratch the glue, and then the side frame can be taken away.

[0024] like Figure 2 As shown, a heating ring 7 is also included. The heating ring 7 is fixedly connected to the lower side of the outer wall of the glue storage tank 6. The heating ring 7 is controlled to heat the glue in the glue storage tank 6 to prevent the glue in the glue storage tank 6 from solidifying.

[0025] like Figure 1-Figure 2 As shown, it also includes a shell 3, which is fixedly connected to the top rear side of the workbench 1. The shell 3 covers the glue storage tank 6 and the heating ring 7 as a whole. Covering the heating ring 7 with the shell 3 can prevent workers from accidentally touching the heating ring 7 during work, thereby avoiding scalding accidents.

[0026] like Figure 1 As shown, a sponge block 12 is also included. The sponge block 12 is connected between the lower parts of the inner walls on the rear sides of the two inverted U-shaped mounting plates 2. The sponge block 12 can be used to wipe the glue dispensing head 10 to clean the glue remaining at the glue outlet of the glue dispensing head 10.

It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions 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.
