[0034] See the example. Figure 1-6 :
[0035] A battery module dispensing device includes a Y-axis linear module 1, an X-axis linear module 2 disposed on the Y-axis linear module 1, a Z-axis linear module 3 disposed on the X-axis linear module 2, a mounting plate 30 arranged on the slide of the Z-axis linear module 3, and an image capturing component 4 and a dispensing component 5 arranged side by side on the front side of the mounting plate 30.
[0036] In one implementation, the Z-axis linear module 3 is mounted on the slide of the X-axis linear module 2 via a second vertical mounting plate 20. A Y-axis linear module 1 and a second slide rail 10 are respectively arranged at both ends of the X-axis linear module 2, with the Y-axis linear module 1 and the second slide rail 10 arranged parallel to each other. A connecting plate 11 is provided between the slide of the Y-axis linear module 1 and the slider of the second slide rail 10. A first vertical mounting plate 12 is provided on the connecting plate 11, and the X-axis linear module 2 is mounted on the first vertical mounting plate 12. The Y-axis linear module 1 drives the X-axis linear module 2 to move along the Y-axis direction, the X-axis linear module 2 drives the Z-axis linear module 3 to move along the X-axis direction, and the Z-axis linear module 3 drives the mounting plate 30 and its image capturing component 4 and dispensing component 5 to move along the Z-axis direction. Preferably, the Y-axis linear module 1, X-axis linear module 2, and Z-axis linear module 3 are all servo linear modules.
[0037] In one embodiment, the image capturing component 4 includes a first lifting device 40, on which an industrial camera 41 is mounted. The lens of the industrial camera 41 faces downwards, and the first lifting device 40 is used to drive the industrial camera 41 to move up and down.
[0038] In one implementation, a coaxial light source 42 is disposed below the lens of the industrial camera 41. The coaxial light source 42 provides more uniform illumination while avoiding reflections from objects, thus improving the accuracy and reproducibility of machine vision. A ring light source 43 is disposed below the coaxial light source 42, with the light emission channel of the coaxial light source 42 located at the center hole of the ring light source 43. The ring light source 43 is used to highlight changes in the edges and height of the measured object, achieving better illumination and facilitating image capture by the industrial camera 41.
[0039] In one embodiment, a transition block 44 is installed on the lifting platform of the first lifting device 40, and a second mounting plate 45 is installed on the other side of the transition block 44. An industrial camera 41 is mounted on the second mounting plate 45 via a camera mounting plate 46, and a coaxial light source 42 is mounted on the second mounting plate 45 via an upper light source mounting plate 47. A lower light source mounting plate 48 is arranged below the coaxial light source 42, and the upper light source mounting plate 47 is mounted on the second mounting plate 45. A ring light source 43 is mounted on the bottom surface of the lower light source mounting plate 48, and the lower light source mounting plate 48 has a light source opening directly opposite the light emission channel of the coaxial light source 42. It is understood that the industrial camera 41 is connected to the camera mounting plate 46, the coaxial light source 42 to the upper light source mounting plate 47, and the ring light source 43 to the lower light source mounting plate 48 via screws.
[0040] The dispensing assembly 5 includes a second lifting device 50. First slide rails 51 are arranged parallel to and in the same direction on both sides of the second lifting device 50. A connecting block is installed on the lifting platform of the second lifting device 50. An extrusion mounting plate 53 is vertically installed on one side of the connecting block. The extrusion mounting plate 53 is mounted on the sliders of the first slide rails 51 on both sides. An upper extrusion mounting block 54 is vertically arranged on the front side of the extrusion mounting plate 53. A pressure sensor 6 is arranged on the bottom surface of the upper extrusion mounting block 54. An extrusion shaft 56 is connected to the bottom surface of the pressure sensor 6 via a lower extrusion mounting block 55. The extrusion shaft 56 is used to squeeze the glue in the dispensing container 57 so that it is sprayed out from the dispensing nozzle 58. The dispensing nozzle 58 of the dispensing container 57 is equipped with a dispensing valve 59. Preferably, the length of the first slide rail 51 is not less than the lifting stroke length of the second lifting device 50, and first guide rail limiting blocks are arranged at both ends of the first slide rail 51.
[0041] Specifically, two dispensing cylinders 57 are configured, one extrusion shaft 56 and one dispensing container 57. The bottoms of the two dispensing container 57 converge and connect to the dispensing nozzle 58. The two dispensing container 57 are used to hold AB glue. The pressure sensor 6 is used to detect the extrusion pressure of the extrusion shaft 56, which helps to prevent mistaken extrusion and over-extrusion, and ensures extrusion accuracy. At the same time, since the A and B components of AB glue are mixed, the mixed AB glue will begin to solidify, which can easily cause the glue outlet channel of the dispensing nozzle 58 to narrow and the extrusion pressure of the extrusion shaft 56 to increase. As a result, the pressure sensor 6 detects the increased extrusion pressure, which helps to monitor the solidification of AB glue in the dispensing nozzle 58. It is understood that the second lifting device 50 is used to drive the extrusion shaft 56 to rise and fall. When the dispensing valve 59 is opened and the extrusion shaft 56 descends, the extrusion shaft 56 squeezes the glue in the dispensing container 57 so that it is sprayed out from the dispensing nozzle 58, so that the glue can be applied to the position to be dispensed on the battery module 7.
[0042] In one embodiment, the dispensing container 57 is mounted on the mounting plate 30 via a dispensing container mounting block. The dispensing container mounting block includes an upper placement block 52 and a lower placement block 523 below it. The upper placement block 52 is connected to an upper retaining block 521. A receiving groove is formed between the upper placement block 52 and the upper retaining block 521 to facilitate the accommodating of the dispensing container 57. The lower placement block 523 is provided with a dispensing container groove 524. The lower end of the dispensing container 57 is placed in the dispensing container groove 524. An inner through groove is formed in the dispensing container groove 524 so that the dispensing nozzle 58 is arranged downward through the inner through groove. Preferably, the upper placement block 52 and the upper retaining block 521 are connected by a pin 522.
[0043] In one embodiment, a dispensing station is set below the dispensing assembly 5. The dispensing station is used to place the battery module 7 to be dispensed. A camera calibration block 8 and a waste glue cup 9 are arranged on one side of the dispensing station. The camera calibration block 8 is located within the shooting field of the industrial camera 41. The waste glue cup 9 is arranged within the travel range of the dispensing nozzle 58, so that waste glue can be squeezed out and discharged into the waste glue cup 9 during use.
[0044] In one embodiment, a first cable protection drag chain 13 is mounted on the upper side of the Y-axis linear module 1, and a second cable protection drag chain 14 is mounted on the upper side of the connecting plate 11. Preferably, both the first cable protection drag chain 13 and the second cable protection drag chain 14 are arranged on the drag chain plate 19, and the surface of the drag chain plate 19 is provided with a drag chain placement groove.
[0045] The first vertical mounting plate 12 is provided with a first connector mounting plate 15 on the side near the Y-axis linear module 1, and the second vertical mounting plate 20 is provided with a second connector mounting plate 21 on its upper part; the moving end of the first cable protection drag chain 13 is connected to the first connector mounting plate 15 through a corresponding drag chain connector, the fixed end of the first cable protection drag chain 13 is mounted on the drag chain plate 19 erected on the upper side of the Y-axis linear module 1 through a corresponding connector bracket, the moving end of the second cable protection drag chain 14 is connected to the second connector mounting plate 21 through a corresponding drag chain connector, and the fixed end of the second cable protection drag chain 14 is mounted on the drag chain plate 19 erected on the upper side of the connecting plate 11 through a corresponding connector bracket.
[0046] In one implementation, the Y-axis linear module 1 and the second slide rail 10 are respectively arranged on gantry frames 16 on both sides. Each gantry frame 16 includes two columns, with a crossbeam atop each column. A mounting bracket 17 is mounted on each column of the gantry frame 16, and a barcode scanner 18 is mounted on the mounting bracket 17. It is understood that the barcode scanner 18 is an industrial barcode scanner, which is mounted on the mounting bracket 17 with screws.
