[0052] Referring to Figure 1 The anti-winding multi-head dispensing equipment provided by the embodiment comprises at least two visual dispensing modules 100 for visual inspection and dispensing of workpieces, and a driving unit 200 for driving each visual dispensing module 100 to move above the workpiece;

[0053] The visual dispensing module 100 comprises a dispensing head 1 for dispensing, a camera 2 for visual inspection of the workpiece, a CCD rotary driving mechanism 3 for driving the camera 2 to rotate around a vertical axis, and a rotary wire fixing device 4.

[0054] The camera 2 is connected with a communication cable 201, and the communication cable 201 is arranged to rotate relative to the CCD rotary driving mechanism 3 through the rotary wire fixing device 4, so that when the CCD rotary driving mechanism 3 drives the camera 2 to rotate, the communication cable 201 rotates with the camera 2.

[0055] In the embodiment, the driving unit 200 is a one-way linear driving mechanism. In some other embodiments, the driving unit 200 can also be a two-way linear driving module or a three-way linear driving module.

[0056] The anti-winding multi-head dispensing equipment provided by the embodiment can perform dispensing work when needed:

[0057] (1) Each visual dispensing module 100 moves above the workpiece under the action of the driving unit 200. The camera 2 in the visual dispensing module 100 starts to perform visual inspection on the workpiece to obtain the top surface and side surface visual information of the workpiece. Since the camera 2 is equipped with the CCD rotary driving mechanism 3 and the rotary wire fixing device 4, the camera 2 can rotate around the vertical axis without winding the communication cable 201, thereby realizing omnidirectional visual inspection of the workpiece.

[0058] It should be noted that during the rotation of the camera 2, the communication cable 201 rotates synchronously with the CCD rotary driving mechanism 3 through the rotary wire fixing device 4, avoiding the winding of the cable due to the movement of the camera 2. In this way, the camera 2 can rotate around the workpiece to collect the visual information of the top surface and the side surface of the workpiece, thereby improving the accuracy of visual inspection.

[0059] (2) Dispensing work: After completing the visual inspection and obtaining the accurate position information of the workpiece, the dispensing head 1 in the visual dispensing module 100 starts to perform dispensing work. Since the equipment comprises at least two visual dispensing modules 100, dispensing can be performed on different workpieces or different positions of the same workpiece simultaneously or sequentially, thereby improving the dispensing efficiency.

[0060] Need to explain, under the accurate control of the driving unit 200, each visual point glue module 100 can work independently or cooperatively, realize the quick, efficient dispensing of workpiece. Meanwhile, the multi-head dispensing design makes the equipment can complete multiple point dispensing operation at the same time, further improves the production efficiency.

[0061] Therefore, the anti-winding multi-head dispensing equipment can effectively solve the problems of low visual detection accuracy and dispensing efficiency of the existing dispensing equipment.

[0062] In the embodiment, the visual dispensing module 100 further comprises a module fixed bottom plate 5 connected with the driving end of the driving unit 200, a lifting support 6 slidingly connected with the module fixed bottom plate 5, and a support linear driving mechanism 7 driving the lifting support 6 to slide up and down relative to the module fixed bottom plate 5.

[0063] Among them, the dispensing head 1, the camera 2, the CCD rotary driving mechanism 3 and the rotary wire fixing device 4 are all installed on the lifting support 6. When the lifting support 6 is driven by the support linear driving mechanism 7 to move up and down, the dispensing head 1, the camera 2, the CCD rotary driving mechanism 3 and the rotary wire fixing device 4 all move up and down synchronously.

[0064] Optionally, the lifting support 6 comprises a vertical sliding plate 601 connected with the driving end of the support linear driving mechanism 7, a horizontal mounting plate 602 fixed at one end of the vertical sliding plate 601, and a reverse L-shaped cover 603 fixed at the other end of the horizontal mounting plate 602.

[0065] Among them, the dispensing head 1 is fixedly arranged at the lower part of the vertical sliding plate 601; the CCD rotary driving mechanism 3 is fixedly arranged on the horizontal mounting plate 602, and the driving end of the CCD rotary driving mechanism 3 protrudes downward below the horizontal mounting plate 602 and is connected with the camera 2 below the horizontal mounting plate 602.

[0066] In the embodiment, the reverse L-shaped cover 603 comprises a vertical part fixedly connected with the horizontal mounting plate 602 at the lower end, and a horizontal part fixedly arranged at the top end of the vertical part and extending above the CCD rotary driving mechanism 3, wherein the rotary wire fixing device 4 is fixedly arranged on the horizontal part.

[0067] When the driving end of the CCD rotary driving mechanism 3 rotates, the camera 2 rotates immediately, and in turn drives the communication cable 201 to rotate. During the rotation of the communication cable 201, the rotary wire fixing device 4 is always adaptively rotated with the communication cable 201 to prevent the communication cable 201 from being wound and broken.

[0068] Referring to Figure 2Optionally, the rotating wire fixing device 4 comprises a rotating bearing 401, a wire clamping base 402 and a wire clamping top cover 403. The outer ring of the rotating bearing 401 is fixed on the horizontal part; the wire clamping base 402 is located above the rotating bearing 401 and is fixed with the inner ring of the rotating bearing 401; the wire clamping top cover 403 is detachably connected with the wire clamping base 402 to clamp the communication cable 201. The rotating action of the wire clamping base 402 and the wire clamping top cover 403 is realized by the bearing, which is low in price and helps to reduce the material cost.

[0069] In the embodiment, the axis of the rotating bearing 401 is collinear with the axis of the CCD rotating driving mechanism 3. Such a structure design helps to reduce the uneven stress of the communication cable 201 during rotation, thereby improving the smoothness of the communication cable 201 during rotation and reducing the rotation resistance of the CCD rotating driving mechanism 3.

[0070] In summary, the anti-winding multi-head dispensing equipment provided by the embodiment has the following advantages:

[0071] ① Improve the visual detection accuracy: by being equipped with the CCD rotating driving mechanism 3 and the rotating wire fixing device 4, the camera 2 can rotate around the vertical axis without winding the communication cable 201, realizing omnidirectional visual detection of the workpiece and improving the visual detection accuracy.

[0072] ② Improve the dispensing efficiency: the equipment comprises at least two visual dispensing modules 100, which can simultaneously or sequentially dispense different workpieces or different positions of the same workpiece, greatly improving the dispensing efficiency.

[0073] ③ Reduce the rotation resistance: the axis of the rotating bearing 401 is collinear with the axis of the CCD rotating driving mechanism 3, which helps to reduce the uneven stress of the communication cable 201 during rotation, improve the rotation smoothness and reduce the rotation resistance.

[0074] It should be noted that the linear driving mechanism mentioned in the utility model can be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a motor screw linear module, and the rotating driving mechanism mentioned can be a brush motor, a brushless motor or a rotary cylinder.
