[0024] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0025] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, this embodiment proposes a fully automatic glue dispensing device, including a glue dispensing platform 1 and a positioning bracket and a slide 2 arranged at the upper end of the glue dispensing platform 1, a positioning plate 6 is arranged at the bottom of the positioning bracket, and two groups of glue dispensing seats 7 are arranged on the front of the positioning plate 6, and a glue dispenser 8 is fixedly connected to the glue dispensing seat 7; A guide rail 17 is laid on the side of the positioning plate 6 facing the dispensing seat 7, and two sets of sliders 18 are sleeved on the guide rail 17. The sliders 18 are slidably connected to the guide rail 17, and the sliders 18 are fixedly connected to the dispensing seat 7; The circuit board is fixed on the top of the slide 2, and the two sets of glue dispensers 8 are respectively fixed to the two sets of glue dispenser seats 7. The glue dispenser seats 7 are slidably set on the front of the positioning plate 6 through the slider 18. When the positioning bracket pushes the positioning plate 6 to fall, the two sets of glue dispensers 8 also fall down. The design of double glue heads can perform glue dispensing operations at the same time, further improving the glue dispensing efficiency.

[0026] An adjustment slot 10 is provided at the upper end of the positioning plate 6, and two groups of adjustment blocks 14 are slidably arranged in the adjustment slot 10. A synchronous adjustment mechanism for adjusting the distance between the two groups of adjustment blocks 14 is provided in the adjustment slot 10; An elastic pin A for fixing the slider 18 is slidably provided on the adjusting block 14 , and an inclined wedge mechanism A for pulling the elastic pin A out from the top of the slider 18 after the adjusting block 14 approaches is provided on the left and right sides of the adjusting slot 10 .

[0027] The two groups of sliders 18 are respectively fixed to the two groups of dispensing seats 7. The sliders 18 are fixed to the adjustment blocks 14 through elastic pins A. The distance between the two groups of adjustment blocks 14 is synchronously adjusted through the adjustment mechanism to change the spacing between the two groups of dispensing seats 7. Through reasonable layout and synchronous control, the accuracy and flexibility of dispensing can be better guaranteed.

[0028] To facilitate the replacement of the glue dispensing seat 7 and the glue dispenser 8, after the adjustment mechanism moves the adjustment block 14 to the left and right sides of the adjustment slot 10, the inclined wedge mechanism A on the left and right sides of the adjustment slot 10 will cooperate with the elastic pin A on the adjustment block 14 to push the elastic pin A away from the slider 18, and simultaneously release the fixation between the two groups of adjustment blocks 14 and the two groups of sliders 18, and slide the glue dispensing seat 7 to the two ends of the guide rail 17, so that the glue dispensing seat 7 can be completely removed from the two ends of the guide rail 17, which is convenient for disassembly and replacement.

[0029] About the regulatory agencies: The adjusting mechanism includes a double-headed screw 12 and a motor 13. The double-headed screw 12 is rotatably connected to the inner side of the adjusting groove 10. Two sets of adjusting blocks 14 are both sleeved on the outer side of the double-headed screw 12. The double-headed screw 12 is threadedly connected to the adjusting blocks 14. The motor 13 is fixedly connected to the outer side of the positioning plate 6. The output end of the motor 13 is fixedly connected to the double-headed screw 12.

[0030] The adjustment mechanism uses a common screw transmission method to control the two groups of adjustment blocks 14. Specifically, the motor 13 drives the double-headed screw 12 to rotate, and the double-headed screw 12 cooperates with the adjustment block 14 to drive the adjustment block 14 to move along the rod of the double-headed screw 12. Due to the different rotation directions of the two threads on the outer side of the double-headed screw 12, the two groups of adjustment blocks 14 will move in opposite directions along the rod of the double-headed screw 12.

[0031] Furthermore, in order to improve the smoothness of the sliding of the slider 18 during the adjustment process of the adjustment mechanism, a guide groove 11 is opened at the lower end of the positioning plate 6, and two groups of guide blocks 15 are slidably arranged in the guide groove 11. A limiting rod 19 is fixedly connected in the guide groove 11, and the limiting rod 19 penetrates the two groups of guide blocks 15. The guide block 15 is slidably connected to the guide groove 11, and an elastic pin B for fixing the slider 18 is slidably arranged on the guide block 15.

[0032] The guide block 15 at the lower end of the positioning plate 6 is fixed to the slider 18 by an elastic pin B. When the slider 18 slides along the guide rail 17, the guide block 15 will also slide along the rod body of the limiting rod 19. The limiting rod 19 cooperates with the guide block 15 to guide the slider 18 from the bottom of the slider 18. During the guiding, the elastic pin B will cooperate with the elastic pin B to limit the slider 18 from the bottom of the slider 18. The upper and lower ends are limited at the same time, which can effectively prevent the slider 18 from falling off when sliding, and has better safety.

[0033] It is worth further explaining that the left and right sides of the guide slot 11 are provided with an inclined wedge mechanism B for pulling out the elastic pin B from the bottom of the slider 18 after the guide block 15 approaches. Similarly, after the slider 18 drives the guide block 15 to move to the left and right sides of the guide slot 11, the inclined wedge mechanism B on the left and right sides of the guide slot 11 will cooperate with the elastic pin B on the guide block 15 to push the elastic pin B away from the bottom of the slider 18, and simultaneously release the fixing of the slider 18 by the guide block 15.

[0034] About elastic pin A and elastic pin B: The elastic pin A and the elastic pin B each include at least two pin rods 24, the pin rod 24 is fixedly connected with a spring plate 16 at one end away from the slider 18, a spring 26 is fixedly connected between the spring plate 16 and the adjusting block 14 and between the spring plate 16 and the guide block 15, the spring 26 is sleeved on the outside of the pin rod 24, the adjusting block 14 and the guide block 15 are sleeved on the outside of the pin rod 24, the adjusting block 14 and the guide block 15 are slidably connected with the pin rod 24, and a slot 25 adapted to the pin rod 24 is provided at the upper and lower ends of the slider 18.

[0035] When the slider 18 moves to between the adjusting block 14 and the guide block 15, the pins 24 on the adjusting block 14 and the guide block 15 are inserted into the slots 25 provided at the upper and lower ends of the slider 18 under the push of the spring 26. The pins 24 cooperate with the slots 25 to limit the slider 18 from the top and bottom walls of the slider 18. To release the limit, the upper and lower pins 24 can be pulled out from the slots 25.

[0036] About the wedge mechanism A and the wedge mechanism B: The inclined wedge mechanism A and the inclined wedge mechanism B both include a second inclined wedge block 27 and a first inclined wedge block 20. The second inclined wedge block 27 is fixedly connected to the left and right sides of the adjustment groove 10 and the guide groove 11. The first inclined wedge block 20 is fixedly connected to the back side of the spring plate 16. The first inclined wedge block 20 is provided with a first inclined surface 22 facing the side of the second inclined wedge block 27. The second inclined surface 21 is provided with a second inclined surface 21 facing the side of the first inclined wedge block 20. The second inclined surface 21 is slidably matched with the first inclined surface 22.

[0037] When the adjusting block 14 and the guide block 15 are pushed to the left and right sides of the adjusting groove 10 and the guide groove 11 under the action of the adjusting mechanism, the first inclined wedge block 20 fixed to the spring plate 16 will collide with the second inclined wedge block 27, the second inclined surface 21 contacts the first inclined surface 22, and the second inclined wedge block 27 pushes the first inclined wedge block 20 along the first inclined surface 22, so that the spring plate 16 moves in the opposite direction of the adjusting block 14 and the guide block 15 until the upper and lower sets of pin rods 24 are pulled out of the slots 25 at the same time.

[0038] In the preferred solution, the positioning bracket includes a bracket 3, which is fixedly connected to the upper end of the dispensing table 1, and an adjusting arm 4 is fixedly connected to the top of the bracket 3. A sliding seat 5 is slidably arranged on the front of the adjusting arm 4, and a lifting member is fixedly connected to the lower end of the sliding seat 5. The lifting member is detachably connected to the positioning plate 6. The positioning bracket is used to adjust the position of the positioning plate 6 on the X-axis, Y-axis and Z-axis, and no further explanation is given here.

[0039] More specifically, the lifting member includes a lifting block 9 and an electric push rod. The lifting block 9 is slidably arranged in a movable groove opened at the lower end of the sliding seat 5. The top of the movable groove is fixedly connected with an electric push rod. The output end of the electric push rod is fixedly connected to the lifting block 9. The lifting block 9 is detachably connected to the positioning plate 6. The height of the positioning plate 6 is controlled by the electric push rod. The movable groove cooperates with the lifting block 9 to limit the lifting block 9. When the lifting block 9 falls, the positioning plate 6 will fall synchronously with the two sets of glue dispensers 8.

[0040] In a preferred solution, the back of the positioning plate 6 is fixedly connected with an assembly plate 23, and bolt holes are provided on the assembly plate 23. The lifting block 9 is equipped with a fixing bolt, and the fixing bolt is threadedly connected with the bolt hole. The lifting member and the positioning plate 6 are fixed by bolt connection, which is convenient for disassembly and maintenance of the positioning plate 6.

[0041] The circuit board is fixed on the top of the slide 2, and the two groups of glue dispensers 8 are fixed to the two groups of glue dispensers 7 respectively. The glue dispensers 7 are slidably arranged on the front of the positioning plate 6 through the slider 18. When the positioning bracket pushes the positioning plate 6 to fall, the two groups of glue dispensers 8 also fall down to dispense glue. The slider 18 is fixed to the adjustment block 14 through the elastic pin A. The distance between the two groups of adjustment blocks 14 is synchronously adjusted by the adjustment mechanism to change the spacing between the two groups of glue dispensers 7. After the adjustment mechanism moves the adjustment block 14 to the left and right sides of the adjustment slot 10, the inclined wedge mechanism A on the left and right sides of the adjustment slot 10 will cooperate with the elastic pin A on the adjustment block 14 to push the elastic pin A off the slider 18, and synchronously release the fixation between the two groups of adjustment blocks 14 and the two groups of sliders 18, and slide the glue dispensers 7 to the two ends of the guide rail 17. The glue dispensers 7 can be completely removed from the two ends of the guide rail 17.
