The transition block 5 is slidably fitted into the grooves of the base 3 and the mold base 4, and the transition block 5 is connected to the base 3 and the mold base 4 by a sliding mechanical seal. The transition block 5 has a transition hole 501. A lifting device is connected to the top of the frame 1. The power output end of the lifting device... A rod base 9 is connected to the rod base 9, and 12 glue-pulling rods 6 are connected to the rod base 9. Each glue-pulling rod 6 is slidably engaged with a glue-pulling hole 401. The glue-pulling hole 401 and the glue-discharging hole 301 are vertically aligned. The glue supply box 2 is connected to the frame 1 and is connected to the glue storage chamber 402. A support rod 10 and a platform 11 are connected to the frame 1. A glue dispensing head 7 is connected to the support rod 10 and is connected to the glue-discharging hole 301. A push-pull device is connected to the platform 11. The push-pull device is driven to connect to the transition block 5. The push-pull device drives the transition block 5 to move so that the transition hole 501 is connected to the glue-pulling hole 401 and the glue-discharging hole 301, or the transition hole 501 is staggered from the glue-pulling hole 401 and the glue-discharging hole 301.
[0030] The upper surface of the base 3 has a concave structure. The two ends of the base 3 are connected to the frame 1 by bolts. There are multiple glue discharge holes 301 arranged side by side. The glue extraction hole 401 on the mold base 4 corresponds to the glue discharge hole 301 vertically.
[0031] The glue supply box 2 is funnel-shaped. The bottom end of the glue supply box 2 is connected to the connector A on the glue storage chamber 402 through the first pipe 13. The glue extraction hole 401 and the glue storage chamber 402 are connected through the inclined flow channel 403.
[0032] The support rod 10 is connected to six clamps 23, and 12 dispensing heads 7 are connected to the clamps 23. The bottom of the dispensing hole 301 is connected to a connector B, and the top of the dispensing head 7 is connected to the connector B through the second pipe 14.
[0033] The lifting device is a vertically arranged first cylinder 8, and the base 3 is connected to one end of the first cylinder 8; the push-pull device is a horizontally arranged second cylinder 12, and the transition block 5 is connected to one end of the second cylinder 12.
[0034] The lower surface of the transition block 5 is slidably fitted to the upper surface of the base 3, and the upper surface and two sides of the transition block 5 are slidably fitted to the groove.
[0035] A controller 15 is connected to the frame 1. The solenoid valves of the first cylinder 8 and the second cylinder 12 are electrically connected to the controller 15, and the foot switch 16 is electrically connected to the controller 15.
[0036] A plug block 17 is connected to the frame 1 below the glue dispensing head 7, and the glue box 18 is inserted into the plug block 17.
[0037] Example 2: This example is a further improvement on Example 1. The main improvement is that, in Example 1, the glue output could not be controlled during use; while in this example, the above-mentioned defects can be avoided. Specifically:
[0038] A screw 19 is connected to the top and bottom of the frame 1. A limiting sleeve 20 is threaded onto the screw 19. A locking nut 21 is connected to the screw 19 at the top of the limiting sleeve 20. The bottom end of the limiting sleeve 20 can contact the top of the rod seat 9.

In addition, the scale 22 is connected to the top and bottom of the frame 1 to facilitate the operator to adjust the position of the adjusting sleeve.
[0039] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.
[0040] The specific working principle of this utility model is as follows:
[0041] During operation, the operator places 12 LED digital tubes side by side on a special fixture and places the plastic casings of the 12 LED digital tubes directly below the 12 dispensing heads 7. The operator presses the foot switch 16, the second cylinder 12 retracts, the glue extraction hole 401, the transition hole 501 and the glue discharge hole 301 are aligned vertically, and at the same time the first cylinder 8 extends, the glue extraction rod 6 moves downward to block the flow channel 403 and squeezes the glue in the glue extraction hole 401 downward, and enters the dispensing head 7 through the second pipe 14, and is poured into the plastic casing of the LED digital tube through the dispensing head 7.
[0042] After the glue is applied, the operator releases the foot switch 16, the second cylinder 12 extends, and the glue extraction hole 401, transition hole 501 and glue discharge hole 301 are staggered, preventing the glue from moving downwards; at the same time, the first cylinder 8 retracts, the glue extraction rod 6 moves upwards, and a negative pressure is formed in the glue extraction hole 401, so the glue in the glue storage chamber 402 will enter the glue extraction hole 401, and the glue extraction hole 401 will be filled with glue for the next batch of LED digital tubes to be applied. The glue in the glue storage chamber 402 is replenished by the first pipe 13.
[0043] After loosening the locking nut 21, the upper and lower positions of the limit sleeve 20 can be adjusted to adjust the stroke of the glue-pulling rod 6, thereby controlling the amount of glue dispensed from the glue-dispensing head 7 to meet different glue application needs.
