[0026] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the embodiments and the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, the utility model discloses an automatic glue dispensing machine 100 based on a marble platform, which includes a marble platform 10, a Y-axis conveying device 20 installed on the marble platform 10, an XZ-axis conveying device 30 installed at the output end of the Y-axis conveying device 20, a double-valve glue dispensing device 40 installed at the output end of the XZ-axis conveying device 30, and a product conveying device 50 installed on the marble platform 10. The product conveying device 50 is arranged below the XZ-axis conveying device 30, and the product conveying device 50 conveys the product along the X-axis and is used to lift, position and fix the product. The Y-axis conveying device 20 drives the XZ-axis conveying device 30 to translate along the Y-axis direction. The XZ-axis conveying device 30 drives the double-valve glue dispensing device 40 to translate along the X-axis and Z-axis, and the double-valve glue dispensing device 40 includes two glue dispensers 41 that are parallel and independently controlled.

[0028] During processing, the product conveying device 50 conveys the product along the X-axis direction. After the product is conveyed to the right position, the product is lifted, positioned and fixed. The Y-axis conveying device 20 drives the XZ-axis conveying device 30 to translate to the top of the product conveying device 50. The XZ-axis conveying device 30 drives the double-valve dispensing device 40 to translate in the X-axis and Z-axis directions, so that the double-valve dispensing device 40 is located directly above the product and close to the product. The two dispensers 41 drip / apply the glue liquid to a specific part of the product. During this process, the Y-axis conveying device 20 and the XZ-axis conveying device 30 also move, driving the product conveying device 50 to translate along at least one of the X, Y, and Z-axis directions.

[0029] In the present invention, the double-valve dispensing device 40 includes two parallel dispensing devices 41, which work independently to improve production efficiency and flexibility. The two dispensing devices 41 can output different glues to achieve a variety of complex dispensing processes.

[0030] The utility model adopts a marble platform 10 as the support of the whole machine. During the high-speed dispensing movement, the shock absorption performance of the marble platform 10 ensures high precision during the dispensing process. The marble platform 10 is integrally cast and processed in one step, so that the precision remains unchanged under the use environment of 20-40°C. There is basically no stress release during the use process, which can ensure the stability of long-term operation. The automatic dispensing machine 100 based on the marble platform of the utility model can perform fully automatic dispensing, reduce manual intervention, and improve production efficiency.

[0031] Preferably, the products to be processed by the utility model include but are not limited to FPC boards and PCB boards, and the glue dispensing is to dispense glue to the components on the FPC boards and PCB boards. The Y-axis conveying device 20 and the XZ-axis conveying device 30 are driven by linear motors, which have higher acceleration response and meet the high position accuracy requirements.

[0032] like Figure 1 and Figure 2 As shown, the double valve dispensing device 40 of the utility model also includes a fine adjustment drive group 42, one of the two dispensing devices 41 is fixedly arranged, and the other of the two dispensing devices 41 is installed at the output end of the fine adjustment drive group 42, and the fine adjustment drive group 42 drives the dispensing device 41 to perform translation adjustment in any direction of the XYZ axis direction. The fine adjustment drive group 42 can drive one of the dispensing devices 41 to perform fine adjustment compensation in the XYZ direction to adapt to the dispensing position.

[0033] like Figure 1 and Figure 2As shown, the double-valve dispensing device 40 of the utility model also includes a visual positioning component 43 installed at the output end of the XZ axis conveying device 30. The visual positioning component 43 can ensure the accuracy and stability of the dispensing process. After the product conveying device 50 lifts, positions and fixes the product, the visual positioning component 43 takes a photo of the product to find the coordinates of the mark point and the board, uploads the photographed data to the controller and issues instructions to control the Y axis conveying device 20 and the XZ axis conveying device 30 to control the dispensing device 41 to spray the required amount of glue according to the set path. Preferably, the visual positioning component 43 adopts a CCD visual system to ensure the accuracy and stability of the dispensing process.

[0034] like Figure 1 and Figure 3 As shown, the automatic glue dispensing machine 100 based on the marble platform of the utility model also includes an auxiliary platform 60 arranged beside the product conveying device 50. The auxiliary platform 60 is installed with an electronic scale 61. The glue dispenser 41 moves to the top of the electronic scale 61, and the glue dispenser 41 dispenses glue normally in the electronic scale 61. The computer displays the weight, and then determines whether the glue output of the glue dispenser 41 is normal, which is convenient for timely correction. According to actual production needs, the above process can be measured once half a day, but it can also be measured once after a certain number of glue dispensing times, and appropriate intervals can be taken accordingly, which is not particularly limited here.

[0035] like Figure 1 and Figure 3 As shown, the auxiliary platform 60 is equipped with a vacuum glue suction device 62 for sucking the residual glue at the outlet of the glue dispenser 41. The vacuum glue suction device 62 can suck the residual glue at the outlet of the glue dispenser 41 to ensure clean glue dispensing and a qualified glue output. It should be noted that after each glue dispensing, the vacuum glue suction device 62 can be used to suck away the residual glue at the outlet of the glue dispenser 41. Of course, the vacuum glue suction device 62 can also be used to suck away the residual glue at the outlet of the glue dispenser 41 after a certain number of glue dispensing times or a certain glue dispensing time.

[0036] like Figure 1 and Figure 3 The auxiliary platform 60 is also equipped with a glue discharge cup 63. The electronic scale 61, the glue discharge cup 63 and the vacuum glue suction device 62 are arranged in sequence along the X-axis direction. Preferably, two glue discharge cups 63 are installed side by side on the auxiliary platform 60. During the machine adjustment process, the glue is discharged once before weighing, and the two glue dispensers 41 discharge the glue liquid in them into the glue discharge cup 63 respectively, so as to facilitate the collection of the glue liquid.

[0037] like Figure 1 , Figure 4 and Figure 5As shown, the product conveying device 50 includes a conveyor base 51, a conveyor belt 52, a stopper 53, a lifter 54 and a heating platform 55. The conveyor belt 52 is installed on the conveyor base 51, and the heating platform 55 is arranged on the conveyor base 51. The conveyor belt 52 conveys the heating platform 55 along the X-axis direction. The stopper 53 is used to block the heating platform 55 that is conveyed in translation. The lifter 54 lifts the heating platform 55 blocked by the stopper 53 along the Z-axis direction and fixes the heating platform 55. After the product is placed on the heating platform 55, the heating platform 55 can heat the product, and the glue dripping onto the product can maintain a certain fluidity for better bonding. The stopper 53 blocks the heating platform 55 that is transported to the right position, so that the heating platform 55 stops at a specified position, and the lifter 54 lifts the heating platform 55, and then glue dispensing can be performed.

[0038] Preferably, multiple groups of stoppers 53 and multiple groups of lifters 54 are provided on the conveyor base 51, so that multiple boards can be conveyed and lifted at the same time, thereby improving production efficiency. The stoppers 53 are driven by cylinders, but not limited thereto, and the lifters 54 are driven by cylinders, but not limited thereto. The conveyor belt 52 is a common tape, and of course, a structure similar to a chain belt can also be used.

[0039] Furthermore, a sensor (not shown) for sensing the position of the heating platform 55 is installed on the conveyor base 51. After the sensor senses that the heating platform 55 has reached the corresponding position, it sends a signal to the stopper 53 and the lifter 54. The stopper 53 blocks the heating platform 55, and the lifter 54 lifts the blocked heating platform 55, so that the heating platform 55 leaves the conveyor belt 52, realizing automatic action. The conveyor base 51 is arranged with adjustable width to accommodate heating platforms 55 of different widths.

[0040] Specifically, the conveyor base 51 includes a first base 511 that is fixedly arranged and a second base 512 that can be translated along the Y-axis direction. A conveying space for accommodating the heating platform 55 is enclosed between the first base 511 and the second base 512, and the translation of the second base 512 along the Y-axis direction enables the conveying space to be set with an adjustable width. Preferably, the first base 511 and the second base 512 are arranged in parallel, but not limited to this. The second base 512 can be driven to translate along the Y-axis by a motor and a screw nut pair, and the accuracy is relatively high. In addition, the second base 512 can also be slidably installed on a conveying rail arranged along the Y-axis to ensure the accuracy of the translation and the smoothness of the movement.

[0041] After the dispensing is completed, the lifter 54 drives the carried heating platform 55 to descend, so that the product falls back onto the conveyor belt 52, flows into the next buffer area for heating, and then the product flows out.

[0042] like Figure 1As shown, the upper end of the marble platform 10 forms an installation space 11 with an inwardly concave setting, and the product conveying device 50 and the auxiliary platform 60 are fixed in the installation space 11. A slide rail 12 extending along the Y axis is installed on the top of the marble platform 10, and the XZ axis conveying device 30 is slidably installed on the slide rail 12. The product conveying device 50, the auxiliary platform 60, the Y axis conveying device 20 and the XZ axis conveying device 30 are all installed on the marble platform 10, which helps to absorb the vibration generated by each module and ensure high-precision dispensing. The installation space 11 is set to accommodate the product conveying device 50 and the auxiliary platform 60, making the overall structure more compact.
