The existing dispensing device generally includes a dispensing mechanism and a fixture mechanism. The dispensing mechanism is used to dispense glue on the product fixed by the fixture mechanism. The traditional fixture mechanism can only realize the positioning and fixing of the product. After the product is dispensed, it will not pre-press the product, but transfer the product to a special pressure-maintaining mechanism for compaction. Although this method can maintain the pressure of the product, it is generally used in assembly lines and is not applicable to separately set dispensing mechanisms. Therefore, since the glue solidifies in a short time, the product can be pre-pressed for a short time in advance during the gap period of glue solidification to enhance the bonding effect of the product.

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2 As shown, the automatic dispensing device provided in the embodiment of the present application has a structure including a frame 1, a feeding mechanism 2 arranged on the frame 1, a dispensing mechanism 3 arranged on the frame 1 for dispensing glue to the product on the feeding mechanism 2, and also includes a clamping mechanism 4, the feeding mechanism 2 includes a fixture 21 provided with a mounting groove 200, a support 23 arranged on the frame 1, and a rotating drive component 22 arranged on the support 23 for driving the fixture 21 to rotate, the clamping mechanism 4 includes a No. 1 clamping component and a No. 2 clamping component respectively arranged on both sides of the fixture 21, the No. 1 clamping component includes a No. 1 cylinder 41 arranged along the Y direction and a No. 1 pressure plate 42 arranged at the output end of the No. 1 cylinder 41, and the No. 2 clamping component includes a No. 2 cylinder 43 arranged along the Y direction and a No. 2 pressure plate 44 arranged at the output end of the No. 2 cylinder 43.

[0019] like Figure 4 As shown, it should be noted that the products include product A101 and product B102, and product A101 is provided with a docking groove for installing product B102.

[0020] In actual use, first, the mounting groove 200 of the fixture 21 is kept vertical with the groove facing upward, then the product A101 is placed in the mounting groove 200, and then the glue is dispensed through the glue dispensing mechanism 3, and then the product B102 is placed in the docking groove of the product A101. After the glue is dispensed, the rotary drive component 22 drives the fixture 21 to rotate 90°, and then the No. 1 clamping component and the No. 2 clamping component move relative to each other, so that the No. 1 cylinder 41 drives the No. 1 pressure plate 42 to abut against the part of the rotary drive component 22 corresponding to the fixture 21, and the No. 2 cylinder 43 drives the No. 2 pressure plate 44 to press the product to the side of the No. 1 pressure plate 42.

[0021] In the above design, the glue dripping on the product can be completed quickly, and the product can be pre-pressed after the glue dripping to ensure the connection and fixing effect of the glue dripping on the product.

[0022] Specifically: Figure 2 As shown, the support 23 includes a No. 1 seat and a No. 2 seat arranged on the frame 1 along the X direction, the rotation drive assembly 22 includes a No. 1 ball bearing 221 arranged on the No. 1 seat, a No. 2 ball bearing arranged on the No. 2 seat, a rotating part 223 fixedly connected to the inner ring of the No. 1 ball bearing 221 and the inner ring of the No. 2 ball bearing, and a No. 1 motor 224 arranged on the No. 2 seat for driving the rotating part 223 to rotate, and the fixture 21 is fixedly set on the rotating part 223.

[0023] In actual use, the rotating part 223 is driven by the No. 1 motor 224 to rotate 90°, so that the rotating part 223 drives the fixture 21 to rotate 90° synchronously, and then the product on the fixture 21 is synchronously rotated 90°, from a vertical state to a horizontal state.

[0024] In the above design, the structural design and specific implementation of the support 23 and the rotation drive assembly 22 facilitate the 90° driving of the fixture 21 .

[0025] Specifically: Figure 2 As shown, a No. 1 disk 226 is coaxially fixedly provided on the rotating part 223, and an infrared photoelectric 225 is also provided on the No. 2 seat. The No. 1 disk 226 extends into the sensing area of ​​the infrared photoelectric 225, and a avoidance hole 201 for avoiding the infrared light of the infrared photoelectric 225 is radially provided on the No. 1 disk 226. When the avoidance hole 201 avoids the infrared light of the infrared photoelectric 225, the motor stops driving.

[0026] In actual use, when the rotating part 223 drives the fixture 21 to rotate, so that the product rotates from a vertical state to a horizontal state, the infrared light of the infrared photoelectric 225 is shielded by the No. 1 disk 226 and is avoided by the avoidance hole 201. Thus, the entire PLC system senses the information that the rotating part 223 has rotated to the right position, and controls the No. 1 motor 224 to stop rotating.

[0027] In the above design, it is convenient to automatically and accurately control the rotation angle of the rotating part 223, thereby ensuring that the product can be stopped from driving in time.

[0028] Specifically: Figure 1 As shown, the glue dispensing mechanism 3 includes a glue dispensing gun 31, a mounting seat 32 arranged on the frame 1, and a three-axis driving component 33 arranged on the mounting seat 32 for driving the glue dispensing gun 31 to move in three axes.

[0029] In actual use, the glue dispensing gun 31 is driven by the third driving component to move along the three directions of X, Y and Z, so that the glue dispensing gun 31 can complete the glue dispensing requirements.

[0030] In the above design, the structural design and specific implementation method of the glue dispensing mechanism 3 can effectively realize the automatic movement of the glue dispensing gun 31 along the glue dispensing path.

[0031] Specifically: Figure 3 As shown, the three-axis driving assembly 33 includes a No. 1 linear guide 331 arranged on the mounting seat 32 along the X direction, a No. 1 plate 332 slidably arranged on the No. 1 linear guide 331, a No. 1 synchronous belt assembly 333 arranged on the mounting seat 32 for driving the No. 1 plate 332 to slide along the No. 1 linear guide 331, a No. 2 linear guide 334 arranged on the No. 1 plate 332 along the Y direction, a sliding seat 335 slidably arranged on the No. 2 linear guide 334, a No. 2 synchronous belt assembly 336 for driving the sliding seat 335 to slide along the No. 2 linear guide 334, a No. 3 linear guide 337 vertically arranged on the sliding seat 335, a mounting plate 338 slidably arranged on the No. 3 linear guide 337 for mounting the dispensing gun 31, and a No. 3 synchronous belt assembly 339 arranged on the sliding seat 335 for driving the mounting plate 338 to slide along the No. 3 linear guide 337.

[0032] In actual use, the first plate 332 is driven to move along the X direction by the first synchronous belt assembly 333, so that the sliding seat 335 drives the mounting plate 338 and the glue gun 31 to move synchronously. The second synchronous belt assembly 336 drives the sliding seat 335 to move along the Y direction, so that the mounting plate 338 and the glue gun 31 move synchronously along the Y axis. The third synchronous belt assembly 339 drives the mounting plate 338 to move along the Z direction, so that the glue gun 31 moves synchronously along the Z direction.

[0033] In the above design, the structural design and specific implementation method of the three-axis driving assembly 33 can effectively realize the three-axis driving of the dispensing gun 31.

[0034] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
