Moreover, the clamping baffle 213 and the clamping support rod 214 reduce the phenomenon of deformation of the clamping baffle 213 under force, and ensure that the clamping head 216 is more stable when clamping tightly.

[0035] Example 2: Please refer to Figures 1 to 7 As shown, based on Embodiment 1, this utility model provides a technical solution: the support mechanism 4 includes a support main frame 41 installed on the lower side of the transverse mechanism 3 and an adjustment groove 46 opened in the dispensing seat 13. A moving guide groove 44 is opened on the inner side of the adjustment groove 46, and a moving guide block 45 is slidably installed on the inner side of the moving guide groove 44. A support slide plate 43 is provided at one end of the moving guide block 45. A support slide groove 42 is opened on the surface of the support main frame 41, and the support slide plate 43 is slidably installed in the support slide plate 43. When the sliding seat 32 moves, the support main frame 41 is driven to slide in the adjustment groove 46. The support slide groove 42 and the support slide plate 43 guide and ensure that the support main frame 41 can stably support the sliding seat 32.

[0036] The support mechanism 4 using the above technical solution guides and positions the transverse mechanism 3 when it moves on the dispensing base 13, thereby ensuring greater stability after the lifting linear guide rail 36 moves to a new position, thus making the dispensing mechanism 10 more stable during dispensing.

[0037] Further reading is available. Figures 1 to 7The transverse mechanism 3 includes a fixed base 31 and a sliding base 32 slidably mounted within the fixed base 31. A sliding screw 34 is rotatably mounted on the inner side of one end of the sliding base 32. A sliding motor 35 is fixedly mounted on one end of the fixed base 31. The output shaft of the sliding motor 35 is fixedly connected to one end of the sliding screw 34. A sliding nut 33 is fixedly mounted on one end of the sliding base 32. The sliding nut 33 is threaded onto the sliding screw 34. The sliding motor 35 drives the sliding screw 34 to rotate, and the sliding screw 34 drives the sliding nut 33 and the sliding base 32 to move and adjust the lifting linear guide 36 and the dispensing mechanism 10. The position is determined by applying adhesive to the sealing groove of the waterproof busbar trough shell through the dispensing mechanism 10; a lifting linear guide rail 36 is fixedly installed at one end of the sliding seat 32, and the dispensing mechanism 10 is installed on the lifting linear guide rail 36; one end of the support frame 41 is fixedly installed at one end of the sliding seat 32, and the other end of the support frame 41 is slidably installed on the lower surface of the fixed seat 31, so that the support frame 41 is more stable when moving; a guide strip 37 is provided on the outer side of the sliding seat 32, and a guide groove 38 is opened on the inner wall of the fixed seat 31. The guide strip 37 is slidably installed on the inner side of the guide groove 38, so as to ensure that the sliding seat 32 is more stable after moving.

[0038] The transverse mechanism 3, which adopts the above technical solution, is slidably installed inside the fixed base 31 via the sliding seat 32 during use, which makes it more stable when the sliding motor 35 drives the sliding seat 32 to move. The dispensing mechanism 10 is raised and lowered via the lifting linear guide rail 36, which makes it more convenient to adjust the dispensing position.

[0039] The working principle and usage process of this utility model are as follows: During use, based on the length of the waterproof busbar trough's outer shell, the adjusting motor 23 drives the adjusting worm gear 24 to rotate. The adjusting worm gear 24 drives the adjusting worm wheel 25 and the adjusting screw 26 to rotate. The adjusting screw 26 drives the adjusting nut 27 and the movable clamping seat 22 to adjust their positions. Then, the clamping baffle 213 and the clamping support rod 214 are installed on the support plate 212, with the clamping support rod 214 supported on the clamping baffle 213 for stability. The corresponding clamping head 216 is selected according to the shape of the waterproof busbar trough's outer shell. The clamping cylinder 215 pushes the clamping head 216 to engage and press against the waterproof busbar trough's outer shell. The clamping baffle 213, in conjunction with this, ensures more stable clamping of the waterproof busbar trough's outer shell. The sliding motor 35 drives the sliding screw 34 to rotate, which in turn moves the sliding nut 33 and the sliding seat 32 to adjust the position of the lifting linear guide rail 36 and the dispensing mechanism 10. The dispensing mechanism 10 dispenses adhesive into the sealing groove of the waterproof busbar trough shell. When the sliding seat 32 moves, it drives the main support frame 41 to slide in the adjusting groove 46. The main support frame 41 is stably supported by the support slide groove 42 and the support slide plate 43. The moving motor 131 drives the moving screw 132 to rotate, which in turn moves the moving nut 133 and the moving seat 134 to move. This causes the transverse movement mechanism 3 and the dispensing mechanism 10 to move laterally and fully squeeze the sealant into the sealing groove of the waterproof busbar trough shell.
