[0026] See also Figure 1-Figure 5 , is a flat glue dispensing machine disclosed in the utility model, which mainly includes an assembly line transportation device 1 for fixing products and a glue dispensing device 2 for processing products.

[0027] The assembly line transport device 1 includes a fixed transport module 11 and a mobile transport module 12. The distance between the fixed transport module 11 and the mobile transport module 12 is adjusted by the movement of the mobile transport module 12. The product is placed between the fixed transport module 11 and the mobile transport module 12. The distance between the fixed transport module 11 and the mobile transport module 12 can be adjusted to adapt to products of different sizes, and the compatibility is high. Specifically, the mobile transport module 12 is driven to move by a screw module 13. The screw module 13 includes a motor 131, a screw 132 and a nut seat 133. The screw module 13 is a prior art, and the specific structure of the screw module 13 is not described in this embodiment. One end of the screw rod 132 is connected to the output shaft of the motor 131, and the other end is connected to the fixed transport module 11. The nut seat 133 is threadedly connected to the screw rod 132. The mobile transport module 12 is connected to the nut seat 133 and moves between the motor 131 and the fixed transport module 11. That is, the motor 131 drives the screw rod 132 to rotate, and the rotational motion of the screw rod 132 is converted into the linear motion of the nut seat 133. The nut seat 133 can drive the mobile transport module 12 to move linearly, that is, the distance between the fixed transport module 11 and the mobile transport module 12 can be adjusted at any time to adapt to products of different sizes.

[0028] More specifically, the fixed transport module 11 includes a fixed bracket 111 and a first transport belt 112 disposed on the fixed bracket 111, and the other end of the screw rod 132 is connected to the fixed bracket 111 through a bearing. The mobile transport module 12 includes a mobile bracket 121 and a second transport belt 122 disposed on the mobile bracket 121, and the mobile bracket 121 is connected to the nut seat 133, that is, the product is placed between the first transport belt 112 and the second transport belt 122, and both ends of the product are respectively placed on the upper ends of the first transport belt 112 and the second transport belt 122. When the first transport belt 112 and the second transport belt 122 are driven at the same time, they can drive and transport the product, and specifically adjust the distance between the first transport belt 112 and the second transport belt 122 by moving the mobile bracket 121 to adapt to products of different sizes, thereby improving the compatibility and practicality of the equipment.

[0029] In order to keep the product fixed during processing, the fixed transport module 11 and the mobile transport module 12 are both provided with a clamping assembly 14 for positioning the product, and the clamping assembly 14 includes a clamping cylinder 141 and two clips 142 arranged on the output shaft of the clamping cylinder 141, and the product is fixed between the two clips 142. One of the clips 142 is located above the first transport belt 112 or the second transport belt 122, and the other clip 142 is driven by the clamping cylinder 141 to move from the bottom of the first transport belt 112 or the second transport belt 122 to the upper direction of the clip 142, which plays the role of clamping the product, ensuring that the product can keep a fixed position during the dispensing process, thereby improving the processing accuracy.

[0030] The dispensing device 2 includes a dispensing valve module 21, a positioning module 22 and a three-axis platform module 23. The entire dispensing valve module 21 is arranged above the assembly line transport device 1. The dispensing valve module 21 is used to perform dispensing processing on the product, and the positioning module 22 is used to locate and scan the MARK point of the product dispensing path to ensure the consistency of the dispensing position. The dispensing valve module 21 and the positioning module 22 are both connected to the three-axis platform module 23. The three-axis platform module 23 drives the dispensing valve module 21 to move according to the product position information detected by the positioning module 22, so that the dispensing valve module 21 corresponds to the product position. In this embodiment, the three-axis platform module 23 includes a Y-axis linear motor module 231 for driving the dispensing valve module 21 to move horizontally in the Y-axis direction, an X-axis linear motor module 232 for driving the dispensing valve module 21 to move horizontally in the X-axis direction, and a Z-axis ball screw module 233 for driving the dispensing valve module 21 to move vertically in the Z-axis direction. Further, the X-axis linear motor module 232 is connected to the Y-axis linear motor module 231, the assembly line transport device 1 is arranged along the driving direction of the Y-axis linear motor module 231, the Z-axis ball screw module 233 is connected to the X-axis linear motor module 232, and the dispensing valve module 21 is arranged on the Z-axis ball screw module 233. That is, the dispensing valve module 21 can move in three axial directions, so as to facilitate dispensing operations at any position on the product.

[0031] Specifically, the positioning module 22 includes an upper camera module 221 and a height measuring module 222. The upper camera module 221 and the height measuring module 222 are both arranged on the Z-axis ball screw module 233 in cooperation with the dispensing valve module 21, that is, the upper camera module 221 is signal-connected with the X-axis linear motor module 232 and the Y-axis linear motor module 231. After the upper camera module 221 locates the product position, the X-axis coordinate information and the Y-axis coordinate information of the product are transmitted to the back-end control system. The back-end control system then issues an instruction to start the X-axis linear motor module 232 and the Y-axis linear motor module 231 to operate simultaneously, and adjust the position of the dispensing valve module 21 in the X-axis direction and the Y-axis direction. At the same time, the height measuring module 222 is connected to the Z-axis ball screw module 233 for signal connection. After the height measuring module 222 locates the product position, the Z-axis coordinate information of the product is transmitted to the back-end control system. The back-end control system then issues a command to start the Z-axis ball screw module 233 and adjust the position of the dispensing valve module 21 in the Z-axis direction to smoothly complete the dispensing action, so that the dispensing path can be automatically compensated in the height and width directions, and processing can be performed at any time according to the product position. The entire dispensing process is efficient and precise.

[0032] Furthermore, it also includes a calibration weighing device 3, which is arranged on the side of the assembly line transportation device 1 and below the dispensing device 2. The calibration weighing device 3 is used to quickly align the dispensing needle of the dispensing valve module 21, clear the glue and monitor the stability of the dispensing amount in real time, and has the effect of glue amount deviation alarm. Specifically, the calibration weighing device 3 includes a needle calibration module 31, a glue clearing module 32 and a weighing module 33. The needle calibration module 31 is simultaneously connected to the X-axis linear motor module 232, the Y-axis linear motor module 231 and the Z-axis ball screw module 233 by signal, so as to calibrate the position of the dispensing valve module 21 in the X-axis direction, the Y-axis direction and the Z-axis direction. In cooperation with the upper camera module 221 and the height measuring module 222, the back-end control system can quickly calculate the compensation position of the dispensing valve module 21 in the X-axis direction, the Y-axis direction and the Z-axis direction, and quickly adjust the position of the dispensing valve module 21 in the X-axis direction, the Y-axis direction and the Z-axis direction through the mutual cooperation of the X-axis linear motor module 232, the Y-axis linear motor module 231 and the Z-axis ball screw module 233, thereby improving the position compensation speed of the dispensing path in the width direction and the height, and further improving the processing efficiency. When the dispensing valve module 21 moves to the glue clearing module 32, the glue clearing module 32 performs glue clearing on the dispensing needle of the dispensing valve module 21. The weighing module 33 weighs the dispensing amount of the dispensing valve module 21, which can detect the stability of the dispensing material, realize the glue amount deviation alarm, and further improve the dispensing accuracy.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
