The glue dispensing component 141 includes a glue dispensing needle 1411 and a glue dispensing valve 1412. The glue dispensing needle 1411 is connected to the glue dispensing valve 1412. The glue dispensing valve 1412 is used to control the glue output of the glue dispensing needle 1411. The glue dispensing valve 1412 is connected to the glue supply device 5 through a pipeline; the glue dispensing positioning component 142 includes an industrial camera 1421 and a distance measuring sensor 1422. The industrial camera 1421 is used to photograph the electronic products on the carrier 100 to find the marking points on the electronic products, so as to facilitate the calculation of the distance between the glue coating trajectory of the glue dispensing needle 1411 and the preset trajectory. According to the data, the distance measuring sensor 1422 is used to measure the distance between the needle tip of the dispensing needle 1411 and the electronic product in the Z direction, so as to obtain the height difference between the needle tip of the dispensing needle 1411 and the electronic product on the carrier 100, so as to calculate the movement trajectory of the dispensing needle 1411. The dispensing positioning component 142 can realize the precise positioning of the dispensing needle 1411, thereby improving the accuracy of the movement trajectory of the dispensing needle 1411, and further improving the dispensing accuracy; the driving component 143 is used to drive the dispensing component 141 and the dispensing positioning component 142 to move simultaneously in the X, Y and Z directions; the needle assembly 144 is used to calibrate the position of the dispensing needle 1411, so as to improve the accuracy of the movement trajectory of the dispensing needle 1411.

[0052] Furthermore, the second positioning assembly 132 includes two groups of first positioning blocks 1321, two groups of second positioning blocks 1322 and two groups of second cylinders 1323.

[0053] It is conceivable that the first cylinder 1311 and the second cylinder 1323 are both connected to the gas source through pipelines and control valves.

[0054] In order to facilitate the industrial camera 1421 of the glue dispensing positioning component 142 to capture the marking points on the electronic products, the glue dispensing positioning component 142 in this embodiment is also provided with an illumination light source 1423, which is used to illuminate the electronic products on the carrier 100, serves as fill light, and can improve the recognition rate of the industrial camera 1421.

[0058] In order to enable the carrier 100 to reflux on the glue coating and curing assembly line, the present embodiment further provides a sixth conveying chain 15 on the first frame 11, and the sixth conveying chain 15 is located below the third conveying chain 12. The sixth conveying chain 15 can convey the carrier 100 along the X direction to achieve the reflux of the carrier 100. In order to control the reflux speed of the carrier 100, the present embodiment further provides a third positioning component with the same structure as the first positioning component 131 to stop the refluxed carrier 100 on the sixth conveying chain 15.

[0059] In order to make the glue dispensing needle 1411 more accurate in coating, the accuracy of the initial position of the glue dispensing needle 1411 is particularly important. To this end, the needle alignment assembly 144 in this embodiment is provided with a needle alignment instrument 1441 and a bracket 1442. The bracket 1442 is disposed on the first frame 11, and the needle alignment instrument 1441 is installed on the top of the bracket 1442. The needle alignment instrument 1441 can calibrate the initial position of the glue dispensing needle 1411 so that a more accurate motion trajectory can be calculated later.

[0063] In order to detect the position of the carrier 100 on the third conveying chain 12 so that the control component can control the operation of the first cylinder 1311 and the second cylinder 1323 to position the carrier 100, the present embodiment further provides two groups of proximity sensors, which are electrically connected to the control component. The two groups of proximity sensors are arranged on the first frame 11 at intervals along the X direction, and the two groups of proximity sensors are used to detect the position of the carrier 100 on the third conveying chain 12.

[0067] When the glue coating device 1 is working, the carrier 100 loaded with electronic products is first fed into the third conveyor chain 12 through the through hole on the cover. When the proximity sensor near the input end of the third conveyor chain 12 detects the carrier 100, the cylinder rod of the first cylinder 1311 extends, and the third conveyor chain 12 conveys the carrier 100 and makes the end of the carrier 100 abut against the stopper 1312 to complete the positioning in the X direction. Then, the cylinder rod of the second cylinder 1323 extends, so that the first positioning block 1321 and the second positioning block 1322 are aligned with the carrier 100. Positioning in the Y direction is performed; then, the industrial camera 1421 photographs the carrier 100 and the electronic product to identify the marking points on the carrier 100 and the electronic product, and then calculates the motion trajectory of the glue dispensing needle 1411 through the marking points; then the glue dispensing needle 1411 applies glue on the electronic product according to the calculated motion trajectory; after the gluing is completed, the glue dispensing needle 1411 returns to the initial position, the first cylinder 1311 and the second cylinder 1323 retract, and the third conveying chain 12 transports the carrier 100 and the electronic product to the curing device 2.

[0089] When the glue curing device is working, first, the operator places the electronic product on the carrier 100 located above the first carrier reflow device 3, and locks the electronic product with the carrier 100. Then, the first conveyor chain 33 transfers the carrier 100 and the electronic product to the third conveyor chain 12 of the glue coating device 1. The third conveyor chain 12 transfers the carrier 100 and the electronic product to the glue coating position, and then the glue dispensing mechanism 14 positions and dispenses glue on the electronic product. After the glue dispensing is completed, the third conveyor chain 12 transfers the carrier 100 and the electronic product to the fifth conveyor chain 62 of the carrier transition device 6. It is sent to the fourth conveyor chain 24 of the curing device 2, and then the curing lamp 22 cures the glue on the electronic product; after curing is completed, the fourth conveyor chain 24 transfers the carrier 100 and the electronic product to the second conveyor chain of the second carrier reflow device 4, the operator takes down the electronic product, the second conveyor chain moves downward, and transfers the carrier 100 to the first conveyor chain 33 located below through the seventh conveyor chain 25, the eighth conveyor chain 63, and the sixth conveyor chain 15 in sequence, the first conveyor chain 33 rises with the carrier 100 back to the initial position, waiting for the electronic product to be installed on the carrier 100.
