[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the accompanying drawings of this embodiment specification, the first direction is marked as X, the second direction is marked as Y, and the third direction is marked as Z.

[0018] To address the technical problems of discontinuous and uneven dispensing in existing dispensing equipment when performing arc dispensing, this invention provides a dispensing device suitable for EHD dispensing. This device enables four-axis linkage and adjusts the relative position of the dispensing component needle and the product on the fixture platform in real time by detecting the relative position information detected by the detection component. This improves the continuity, consistency, and uniformity of dispensing, thereby enhancing dispensing quality and efficiency.

[0019] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a dispensing device suitable for EHD dispensing, which includes a frame 1, a fixture module 2 and a dispensing module 3; The fixture module 2 includes an adjustment assembly 21 fixed to the frame 1 and a fixture platform 22 disposed on the adjustment assembly 21. The fixture platform 22 is used to clamp and fix the product to be glued. The adjustment assembly 21 is used to drive the fixture platform 22 along a first direction and a second direction, and to drive the fixture platform 22 to rotate about an axis extending along a third direction. The dispensing module 3 includes a dispensing component 31 and a detection component 32. The detection component 32 is slidably disposed on the frame 1 along the third direction, and the dispensing component 31 is slidably disposed on the detection component 32 along the third direction. The detection component 32 is configured to monitor the position information of the dispensing needle of the dispensing component 31 and use the monitored position information to adjust the movement state of the dispensing component 31 and the adjustment component 21. Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0020] Specifically, in this embodiment, the frame 1 includes a workbench with a side plate vertically mounted on one side. The fixture module 2 is fixed to the workbench, while the dispensing module 3 is mounted on the side plate. The arrangement of the workbench and side plate initially ensures the relative position and state between the dispensing assembly 31 and the fixture platform 22. The adjustment component 21 can drive the fixture platform 22 to move and rotate around an axis extending in a third direction in the horizontal plane, thereby adjusting the position, angle, and orientation of the fixture platform 22 in the plane. That is, when facing the dispensing requirements of the product's arc segment, the adjustment component 21 can more accurately and quickly adjust the relative position, relative angle, and relative orientation between the fixture platform 22 and the dispensing assembly 31, thereby ensuring the continuity and stability of the arc segment dispensing work, avoiding the problem of uneven dispensing caused by discontinuous arc segment dispensing in traditional solutions, and ultimately improving dispensing quality and efficiency.

[0021] Furthermore, the detection component 32 is slidably mounted on the side plate of the frame 1 along a third direction. In actual use, this allows for better adjustment of the relative height between the detection component 32 and the fixture platform 22, thereby enabling more accurate identification and confirmation of the product to be dispensed and the dispensing position on it, thus further improving dispensing accuracy. The dispensing component 31, based on the aforementioned design, is also slidably mounted on the detection component 32. The dispensing component 31 can move relative to the detection component 32 in a third direction, meaning it can be displaced relative to the frame 1 in a third direction. This not only increases the range of motion of the dispensing component 31 but also, through the characteristics of a specific motor module (such as a voice coil motor module), improves the speed and accuracy of the dispensing component 31's movement in height. Specifically, the detection component 32 and its dispensing component 31 are moved along a third direction to a position initially close to the fixture platform 22. Then, based on the relative position and orientation of the fixture platform 22 and the dispensing component 31 detected by the detection component 32, the horizontal position and rotation angle of the fixture platform 22 are precisely adjusted. This ensures that the product to be dispensed is directly below the dispensing component 31. The dispensing component 31 is then precisely moved downwards to the working position, achieving more precise dispensing. Furthermore, during the dispensing process, the adjusting component 21 and the dispensing component 31 will simultaneously make fine adjustments based on the data detected by the detection component 32, ensuring the continuity and uniformity of the dispensing.

[0022] It is understood that in some embodiments, the worktable is made of marble, which has high planar accuracy after processing, thereby ensuring that the equipment has good rigidity after having a good reference datum, and ensuring the stability and reliability of accuracy.

[0023] In some embodiments, the adjustment assembly 21 includes a displacement mechanism 211 and a rotation mechanism 212. The displacement mechanism 211 is fixed to the frame 1, the rotation mechanism 212 is disposed on the displacement mechanism 211, and a fixture platform 22 is disposed on the top of the rotation mechanism 212. The displacement mechanism 211 is configured to drive the rotation mechanism 212 to move along a first direction and / or a second direction, and the rotation mechanism 212 is configured to drive the fixture platform 22 to rotate about an axis extending along a third direction.

[0024] Specifically, to achieve horizontal displacement and axial rotation of the fixture platform 22, the adjustment component 21 in this embodiment is divided into a displacement mechanism 211 and a rotation mechanism 212. The displacement mechanism 211 is mounted on the frame 1, while the rotation mechanism 212 is mounted on the displacement mechanism 211. The displacement mechanism 211 can achieve lateral and longitudinal displacement of the rotation mechanism 212 through a guide rail and a motor, that is, to achieve lateral and longitudinal displacement of the rotation mechanism 212 and the fixture platform 22 on it, thereby adjusting the position coordinates of the fixture platform 22 in the plane so that the product to be dispensed can be accurately moved to directly below the dispensing component 31. The rotation mechanism 212 can be driven by a rotary motor to rotate the fixture platform 22 directly, or the rotary motor can drive the fixture platform 22 to rotate through a transmission structure to meet the continuity requirements of dispensing in the arc segment, thereby improving dispensing quality and efficiency.

[0025] In some embodiments, the displacement mechanism 211 includes a base 2111, a first slide plate 2112 and a second slide plate 2113; the base 2111 is fixed to the frame 1, the first slide plate 2112 is slidably disposed on the top of the base 2111 along a second direction, the second slide plate 2113 is slidably disposed on the top of the first slide plate 2112 along a first direction, and a rotating mechanism 212 is provided on the top of the second slide plate 2113.

[0026] Specifically, in this embodiment, the base 2111 is fixed to the workbench of the frame 1, and a first guide rail extending along a second direction is provided on the base 2111. The first slide plate 2112 is slidably disposed on the top of the base 2111 via the first guide rail. A second guide rail extending along a first direction is provided on the top of the first slide plate 2112, and a second slide plate 2113 is slidably disposed on the top of the first slide plate 2112 via the second guide rail. A rotating mechanism 212 is disposed on the top of the second slide plate 2113. When the position of the fixture platform 22 needs to be adjusted laterally, it is only necessary to drive the second slide plate 2113 to move relative to the first slide plate 2112. When the position of the fixture platform 22 needs to be adjusted longitudinally, it is only necessary to drive the first slide plate 2112 to move relative to the base 2111.

[0027] It is understood that in this embodiment, the first guide rail extends along the second direction, and the second guide rail extends along the first direction. In other embodiments, the first guide rail on the base 2111 may also extend along the first direction. Correspondingly, the second guide rail on the first slide plate 2112 needs to extend along the second direction. Its specific structure is similar to that of this embodiment, and will not be described again here.

[0028] In some embodiments, the displacement mechanism 211 further includes a first drive member 2114 and a second drive member 2115 fixed to the frame 1. The first drive member 2114 is configured to connect to the first slide plate 2112 to drive the first slide plate 2112 to move in a second direction relative to the base 2111. The output end of the second drive member 2115 is fixed with a movable plate 2116. The movable plate 2116 is slidably connected to the second slide plate 2113 along the second direction. The second drive member 2115 is configured to drive the second slide plate 2113 to move relative to the first slide plate 2112 along the first direction through the movable plate 2116.

[0029] Specifically, in this embodiment, the first driving member 2114 and the second driving member 2115 provide driving force to the first sliding plate 2112 and the second sliding plate 2113, respectively, so that the first sliding plate 2112 and the second sliding plate 2113 can slide along a preset direction to adjust the position of the fixture platform 22. To resolve operational conflicts, this embodiment also includes a movable plate 2116. The base 2111 is provided with a third guide rail extending along a first direction corresponding to the movable plate 2116, and the top of the movable plate 2116 is provided with a fourth guide rail extending along a second direction. When it is necessary to adjust the position of the fixture platform 22 along the first direction, the second driving member 2115 can push the movable plate 2116 to move along the third guide rail, thereby driving the second sliding plate 2113 to move along the second guide rail. When the position of the fixture platform 22 needs to be adjusted along the second direction, the first drive member 2114 can push the first slide plate 2112 to move along the first guide rail, while the second slide plate 2113 is pushed to move along the fourth guide rail, thereby realizing the precise movement of the fixture platform 22 on the plane.

[0030] It is understood that in this embodiment, the first drive unit 2114 and the second drive unit 2115 can adopt a structure of motor and lead screw to provide power to the first slide plate 2112 and the second slide plate 2113 respectively. In other embodiments, the first drive unit 2114 and the second drive unit 2115 can also adopt a high-precision linear motor module or other linear drive structure, as long as the accuracy requirements are met, which will not be elaborated here.

[0031] In some embodiments, the rotating mechanism 212 includes a mounting base 2121 fixed to the second slide plate 2113 and a third driving member 2122 fixed to the mounting base 2121; a synchronous wheel 2123 is rotatably disposed on the top of the mounting base 2121, and a jig platform 22 is fixed on the top of the synchronous wheel 2123; the third driving member 2122 is connected to the synchronous wheel 2123 to drive the synchronous wheel 2123 to rotate.

[0032] Specifically, in this embodiment, the rotating mechanism 212 mainly includes a third driving member 2122 and two synchronous pulleys 2123, one large and one small. The third driving member 2122 and the synchronous pulleys 2123 are both mounted on the mounting base 2121, which is fixed on the second slide plate 2113. The third driving member 2122 directly drives the smaller synchronous pulley 2123 to rotate on the mounting base 2121. The smaller synchronous pulley 2123 is connected to the larger synchronous pulley 2123 via a synchronous belt to drive the larger synchronous pulley 2123 to rotate, thereby driving the fixture platform 22 on the larger synchronous pulley 2123 to rotate, thus realizing the rotation of the product to be glued.

[0033] It is understood that, in some other embodiments, meshing teeth can be provided on the inner side of the timing belt and the outer side of the two timing pulleys 2123 to improve accuracy. In other alternative embodiments, other rotating mechanisms 212 may also be used, which will not be described in detail here.

[0034] Furthermore, in this embodiment, an encoder is also installed inside the mounting base 2121. This encoder can detect and record the rotation angle of the large synchronous wheel 2123, thereby controlling the working posture of the third drive component 2122, and thus controlling the rotation angle of the fixture platform 22. Simultaneously, multiple limiting baffles are provided on the fixture platform 22. These limiting baffles can abut against the side wall of the product to be dispensed to limit the relative position of the product and the fixture platform 22. Additionally, multiple negative pressure holes are provided at the bottom of the fixture platform 22. By creating negative pressure on the fixture platform 22, the position of the product to be dispensed is stabilized, thereby ensuring subsequent dispensing accuracy.

[0035] In some embodiments, the detection component 32 includes a fourth drive member 321, a mounting plate 322 and a first camera 323. The fourth drive member 321 is fixedly mounted on the frame 1 and is connected to the mounting plate 322 to drive the mounting plate 322 to move in a third direction. Mounting plate 322 is fixedly provided with a first camera 323 for identifying products, and the front of mounting plate 322 is slidably connected to a dotted adhesive assembly 31 along a third direction.

[0036] Specifically, in this embodiment, the fourth driving component 321 is a linear motor module fixed to the side plate of the frame 1. The output end of the linear motor module is fixedly connected to a mounting plate 322. The mounting plate 322 is fixed with a first camera 323 and slidably connected to a dispensing component 31. In actual use, the fourth driving component 321 first drives the mounting plate 322 to move in a third direction to adjust the position of the first camera 323 and the dispensing component 31, so that the first camera 323 can accurately and clearly identify the feature points of the product to be dispensed on the fixture platform 22 one by one. After the product features are identified, the dispensing component 31 can move together with the mounting plate 322 in a third direction to complete the subsequent dispensing work more accurately.

[0037] It should be noted that, in this embodiment, a specific motor module (including but not limited to a voice coil motor module) is fixedly mounted on the mounting plate. This motor module is used to drive the dispensing assembly 31 to make micro-movements relative to the mounting plate 322 in a three-dimensional direction. When facing application scenarios where the dispensing height of the product fluctuates, only the dispensing assembly 31 follows the adjustment. Compared with the traditional solution where the detection component 32 and the dispensing assembly 31 are relatively fixed, and the mounting plate 322 is moved only by the fourth driving component 321, the dispensing assembly 31 in this embodiment has higher rigidity, movement speed, and accuracy, which can better meet the high-precision requirements of subsequent dispensing.

[0038] It is understood that in some other embodiments, the linear motor module is also equipped with a magnetic spring to counteract the gravitational force of the load on the linear motor module, thereby improving the stability of the dispensing assembly 31 during its up-and-down movement. Furthermore, the dispensing assembly 31 mainly includes an EHD dispensing head, which is existing technology and only needs to be mounted on the mounting plate 322. In addition, the installation angle of the dispensing needle in the dispensing assembly 31 can be adjusted according to actual dispensing needs to further improve dispensing accuracy and thus improve dispensing quality.

[0039] In some embodiments, the first camera 323 includes a height sensor 3231, a camera body 3232, a lens barrel 3233, and a light source 3234. The camera body 3232, the lens barrel 3233, and the light source 3234 are coaxially arranged along a third direction, and the height sensor 3231 is disposed on one side of the light source 3234.

[0040] Specifically, in this embodiment, the height sensor 3231 detects the height of the product at different positions on the fixture plate 22, and the software calculates and determines the product dispensing plane. This allows for more precise adjustment of the movement of the dispensing component 31 along a third direction during dispensing, thereby improving dispensing accuracy. Meanwhile, the light source 3234 illuminates the product to be dispensed on the fixture platform 22. After reflection, the light enters the lens barrel 3233 and finally enters the camera body 3232. The camera body 3232 then acquires the position of the product to be dispensed. The software adjusts the dispensing path through template comparison, thereby achieving real-time adjustment and guidance of dispensing.

[0041] In some embodiments, the mounting plate 322 is sequentially fixedly connected to a first link and a second link, and the end of the second link is fixed with a second camera 324 for monitoring the position of the dispensing assembly 31 needle and the position of the fixture platform 22.

[0042] Specifically, in this embodiment, the mounting plate 322 is further provided with a second camera 324, which is mainly used to observe and monitor the needle of the dispensing assembly 31. The second camera 324 is located on the side of the dispensing assembly 31 away from the first camera 323. The second camera 324 can continuously observe the position of the dispensing assembly 31 during the dispensing process, thereby dynamically adjusting the operation of the displacement mechanism 211 and the rotation mechanism 212, as well as the position of the dispensing assembly 31, to achieve more precise continuous dispensing, thereby improving dispensing quality and efficiency.

[0043] In some embodiments, the frame 1 is fixed with a third camera 325, which is disposed on one side of the fixture platform 22 in the second direction. The third camera 325 is used to monitor the needle position of the dispensing assembly 31 and the position of the fixture platform 22.

[0044] Specifically, in this embodiment, a third camera 325 is also provided. The third camera 325 is mounted on the frame 1 and faces the fixture platform 22 in the second direction. It can observe and monitor the position and state of the dispensing assembly 31 and the fixture platform 22 from the side during the dispensing process. Together with the first camera 323 and the second camera 324, it can provide closed-loop detection for the alignment of the dispensing assembly 31, so that the relative positional accuracy between the needle of the dispensing assembly 31 and the product to be dispensed is higher, the subsequent dispensing will be more controllable, the dispensing quality will be higher, and there will be no problems of dispensing deviation and uneven dispensing.

[0045] In some embodiments, a control module 4 is also included, which includes an industrial computer, a motor driver 41, a high-voltage power supply 42, and a dispensing controller 43. The high-voltage power supply 42 is configured to construct the dispensing electric field. The motor driver 41 is electrically connected to the corresponding motors in the dispensing module 3 and the fixture module 2. The dispensing controller 43 is electrically connected to the dispensing assembly 31 to control the working state of the dispensing assembly 31. The industrial control computer is electrically connected to the adjustment assembly 21, the detection assembly 32 and the dispensing assembly 31 to control the operation of the adjustment assembly 21, the detection assembly 32 and the dispensing assembly 31.

[0046] Specifically, in this embodiment, the high-voltage power supply 42 is used to provide electrical energy to create a suitable electric field for EHD dispensing, while the dispensing controller 43 provides start / stop and gas pressure control for dispensing. Subsequently, the industrial control computer (not shown in the figure) controls the motor driver 41 through software to electrically connect the adjustment component 21, the detection component 32 and the various motors in the dispensing component 31 to achieve linkage dispensing.

[0047] Furthermore, the motor driver 41 is electrically connected to the first drive unit 2114, the second drive unit 2115, the third drive unit 2122, and the fourth drive unit 321, thereby enabling it to receive control signals from the industrial control computer to adjust the relative position and state between the fixture platform 22 and the dispensing assembly 31. The industrial control computer, in turn, makes decisions and issues control signals by receiving information from the first camera 323, the second camera 324, and the third camera 325. Additionally, the high-voltage power supply 42 creates an electric field for the EHD dispensing process; this is existing technology and will not be described further here.

[0048] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
