Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0051] The following is in conjunction with the appendix Figure 1-10 The present invention provides a further description of the compact multi-suction head feeding mechanism and automatic dispensing production line.

[0052] Please refer to this carefully. Figure 1-5In sections 9-10, this utility model discloses a compact multi-head material handling and feeding mechanism 5. The compact multi-head material handling and feeding mechanism 5 is used for handling and feeding sheet-shaped irregular workpieces 05. One side of the sheet-shaped irregular workpiece 05 is provided with a recessed colloid receiving groove 051; the bottom of the colloid receiving groove 051 is provided with a protruding workpiece body 052; the compact multi-head material handling and feeding mechanism 5 includes a suction head assembly 51; the suction head assembly 51 includes a connecting frame; the connecting frame includes: a first frame plate 511 and a second frame plate 512 arranged vertically at intervals, and a connecting plate 511 and the second frame plate 512 in the same direction. The frame vertical plate 513 is located on one side; the suction head assembly 51 also includes n suction heads, each mounted side-by-side in a row on the second frame plate 512, where n is a natural number ≥ 2; the suction head includes: a cylinder fixing plate 515, a slide cylinder 516, a cylinder movable plate 517, an inverted F-shaped mounting bracket 518, a rotary motor 519, and a suction rod 520; the cylinder fixing plate 515 has a plate fixing side and a cylinder mounting side on its two sides, respectively. The plate fixing side is fixed to the upper part of the second frame plate 512, and the cylinder mounting side extends away from the frame vertical plate 513 and protrudes from the second frame plate 512; the slide cylinder 516 includes a cylinder fixing body 516. 1. A cylinder sliding body 5162 and a cylinder fixing body 5161 are installed on the cylinder mounting side. A cylinder movable plate 517 is fixedly installed on the lower part of the cylinder sliding body 5162. The inverted F-shaped mounting bracket 518 is generally inverted "F" shape, and the inverted F-shaped mounting bracket 518 includes a first horizontal bracket plate 5181 and a second horizontal bracket plate 5182 arranged at intervals, and a mounting bracket vertical plate 5183 connecting the first horizontal bracket plate 5181 and the second horizontal bracket plate 5182 on the same side. The top of the mounting bracket vertical plate 5183 is located above the first horizontal bracket plate 5181, and the top of the mounting bracket vertical plate 5183 is fixed to the lower part of the cylinder movable plate 517. The rotary motor 519 is mounted on the top of the first horizontal frame plate 5181, and the output end of the rotary motor 519 passes through the first horizontal frame plate 5181. The lower part of the suction rod 520 is provided with a protruding suction column 5201, and the shape of the suction column 5201 matches the shape of the workpiece body 052. The suction column 5201 is provided with a suction hole 5202 passing through it. The upper part of the suction rod 520 passes through the second horizontal frame plate 5182 and is connected to the output end of the rotary motor 519. The compact multi-suction head material handling and feeding mechanism also includes a material handling robot 52, and the upper part of the first frame plate 511 is mounted on the material handling robot 52.

[0053] In this embodiment, the connecting frame has multiple functions: the first frame plate 511 is used to connect with the picking robot 52 to realize the suction head assembly 51 being mounted on the picking robot 52; the second frame plate 512 is used to centrally install multiple suction heads; and the frame vertical plate 513 is used to fix the first frame plate 511 and the second frame plate 512.

[0054] Regarding the suction head: The cylinder fixing plate 515 is used to fix the suction head to the second frame plate 512. The slide cylinder 516 provides linear extension and retraction power for the suction rod 520. Since each suction head has an individual slide cylinder 516, each suction rod 520 can extend and retract independently. The rotary motor 519 provides rotational power for the suction rod 520. Since each suction head has an individual rotary motor 519, each suction rod 520 can rotate independently. This structure enables each suction head to extend, retract, and rotate independently to pick up workpieces. The cylinder movable plate 517 is used to fix and connect the cylinder sliding body 5162 and the inverted F-shaped mounting bracket 518. The inverted F-shaped mounting bracket 518 provides a mounting base for the rotary motor 519 and the suction rod 520. The suction rod 520 is used to pick up workpieces. During use, the suction column 5201 extends into the colloid receiving tank 051 and aligns with the workpiece body 052. The suction hole 5202 is used to pick up sheet-like irregularly shaped workpieces 05. With this structure, the suction hole 5202 acts directly on the solid workpiece body 052, avoiding suction gaps and ensuring stable adsorption of the entire sheet-like irregularly shaped workpiece 05. Furthermore, during adsorption, the suction column 5201 aligns with the workpiece body 052, providing positioning for the workpiece body 052 and ensuring the accuracy and stability of the feeding process. Each suction head can extend, retract, and rotate independently, adsorbing one workpiece at a time. After adsorbing n workpieces, the entire assembly moves with the picking robot 52.

[0055] In this embodiment, the connecting frame, cylinder fixing plate 515, cylinder movable plate 517, and inverted F-shaped mounting bracket 518 together form a highly compact mounting bracket structure. The gap between adjacent suction heads is small (only ensuring that adjacent cylinder movable plates 517 can slide smoothly individually), enabling highly integrated installation of the suction head assembly 51 and multiple suction heads without affecting the individual extension, retraction, and rotation of each suction rod 520. This makes the suction head assembly 51 compact and small in size while still being functional. With this structure, the gap between adjacent suction heads is small, and in subsequent processes, the gap between the suction heads is the same as the gap between the workpieces on the carrier tray. Therefore, this structure provides conditions for multiple suction heads to simultaneously place multiple workpieces, thus improving loading efficiency.

[0056] The material handling robot 52 is an outsourced component. In specific implementation, an existing multi-axis robot can be selected according to the needs of the operation, or the material handling robot 52 can be assembled from multiple existing linear motion modules. The suction head assembly 51 is used to directly act on the sheet-like irregular workpiece 05, and under the combined action of the material handling robot 52, loading and unloading are realized.

[0057] The following describes in detail the usage process of the compact multi-suction head feeding mechanism 5 of this utility model.

[0058] Multiple sheet-like irregularly shaped workpieces 05 are located within a flexible vibrating plate 82 and laid flat under the action of the vibrating plate 82. A material handling robot 52, carrying a suction head assembly 51, moves above the flexible vibrating plate 82. After one suction head in the suction head assembly 51 is basically aligned with a sheet-like irregularly shaped workpiece 05, the rotary motor 519 rotates, aligning the suction column 5201 with the workpiece body 052. Then, the suction rod 520 extends sequentially and picks up a sheet-like irregularly shaped workpiece 05. The material handling robot 52, carrying another suction head in the suction head assembly 51, aligns with another sheet-like irregularly shaped workpiece 05, and repeats the above steps to complete the adsorption of that sheet-like irregularly shaped workpiece 05. This process is repeated until each suction head adsorbs a sheet-like irregularly shaped workpiece 05, completing the entire material adsorption action. The material handling robot 52, carrying the suction head assembly 51 and the adsorbed sheet-like irregularly shaped workpieces 05, moves as a whole to the fixture carrier plate 7, and simultaneously lowers all the adsorbed sheet-like irregularly shaped workpieces 05, completing the loading process. Since a suction head assembly 51 includes n suction heads, the material handling robot 52 can pick up multiple workpieces in one trip (from the flexible vibratory plate 82 to the fixture carrier plate 7), which greatly improves the efficiency of material loading.

[0059] In summary, the compact multi-head material handling and feeding mechanism 5 of this utility model can stably and accurately adsorb uneven workpieces. Moreover, the compact multi-head material handling and feeding mechanism 5 is highly integrated in structure, with a small overall size and a small distance between adjacent workpieces. When the compact multi-head material handling and feeding mechanism 5 works in conjunction with the material handling robot 52, it can quickly pick up workpieces and pick up multiple workpieces in one trip, thus achieving high feeding efficiency.

[0060] According to a specific embodiment of the present invention, the frame vertical plate 513 is provided with an air pipe through hole 5131 through which the cylinder pipe 514 passes; the suction head assembly 51 also includes a cylinder pipe 514 for providing a pressure air source to the slide cylinder 516, one end of the cylinder pipe 514 being connected to the slide cylinder 516 through the air pipe through hole 5131.

[0061] In this embodiment, the frame vertical plate 513 is also used to form an air pipe through hole 5131, providing conditions for the centralized installation of the cylinder pipe 514.

[0062] According to a specific embodiment of this utility model, the suction rod 520 includes a hollow rod 5203 and an adsorption plate 5204 that are fixedly connected vertically. Both the hollow rod 5203 and the adsorption plate 5204 are cylindrical in shape. The hollow rod 5203 passes through the second horizontal frame plate 5182 and is rotatably connected to the second horizontal frame plate 5182 via a bearing 521. The adsorption column 5201 is located at the lower part of the adsorption plate 5204. The interior of the hollow rod 5203 communicates with the adsorption hole 5202. A vacuum connector 522 communicating with the interior of the hollow rod 5203 is provided on one side of the hollow rod 5203. The adsorption head also includes a coupling 523, and the hollow rod 5203 is connected to a rotary motor 519 via the coupling 523.

[0063] In this embodiment, the structure of the suction rod 520 is designed in more detail.

[0064] The top of the hollow rod 5203 is connected to the rotary motor 519; the hollow hole inside the hollow rod 5203 and the vacuum connector 522 on the side are connected to the vacuum source; the middle section of the hollow rod 5203 is rotatably connected to the second horizontal frame plate 5182 via the bearing 521, which helps to ensure the positional accuracy of the hollow rod 5203; the bottom of the hollow rod 5203 is connected to the adsorption plate 5204, which is used to transmit the rotational power and the vacuum source to the adsorption plate 5204. Furthermore, the suction rod 520 is a stepped structure composed of two cylinders of different sizes. Through the protruding adsorption column 5201 at the bottom, it can adsorb workpieces with irregular shapes. The design is ingenious, the shape is simple, and it is easy to mold.

[0065] As can be seen from the above, the two ends, sides and interior of the suction rod 520 in this embodiment each have their own purpose. The structure is compact, the layout is reasonable, and they do not interfere with each other, so as to realize the function of rotating the suction rod 520 and picking up the workpiece.

[0066] According to a specific embodiment of the present invention, the adsorption head further includes a rotation angle positioning sensor 524 sleeved and fixed on the hollow rod 5203. A photoelectric sensor 525 is provided on one side of the rotation angle positioning sensor 524 to cooperate with the rotation angle positioning sensor 524 and to detect the rotation angle of the suction rod 520. The photoelectric sensor 525 is fixedly installed on the lower part of the second horizontal frame plate 5182.

[0067] In this embodiment, the second horizontal frame plate 5182 is also used to install a photoelectric sensor 525. The photoelectric sensor 525 acquires the rotation angle information of the suction rod 520, and in conjunction with the electrical control system, can precisely control the start and stop of the rotary motor 519, ultimately achieving precise control of the rotation angle of the suction rod 520. It should be noted that both the rotation angle positioning sensor 524 and the photoelectric sensor 525 are purchased components.

[0068] According to a specific embodiment of this utility model, the material handling robot 52 is a four-axis horizontal robot, and the upper part of the first frame plate 511 is mounted on the end of the four-axis horizontal robot.

[0069] In this embodiment, a four-axis horizontal robot is used, which occupies a smaller overall volume and helps to reduce the overall size of the compact multi-suction head material feeding mechanism 5 of this utility model.

[0070] Please refer to this carefully. Figure 6-10 This utility model also discloses an automatic dispensing production line, including: a material conveying line 6, a fixture carrier 7 disposed on the material conveying line 6 and moving with the material conveying line 6, and a feeding unit 8, a dispensing unit 9, and a curing unit arranged sequentially along the conveying direction of the material conveying line 6; the feeding unit 8 includes: a discharge bin 81, a flexible vibrating plate 82, a discharge vision module 83, and a compact multi-suction head feeding mechanism 5 as described in the above embodiment; the discharge bin 81 includes a discharge port 811 facing the flexible vibrating plate 82, and the discharge bin 81 is used to receive sheet-shaped irregular workpieces 05; and the discharge bin 81 is also used to input sheet-shaped irregular workpieces 05 into the flexible vibrating plate 82 through the discharge port 811; the discharge vision module... Block 83 is used to take pictures to determine the front and back sides and position information of the sheet-like irregular workpiece 05. The upper surface of the fixture carrier plate 7 is provided with a recessed workpiece receiving groove 71. The workpiece receiving groove 71 is distributed in a rectangular array. The workpiece receiving groove 71 is arranged in m rows, where m is a natural number ≥ 1. Each row includes n workpiece receiving grooves 71. In each row, the position of the n workpiece receiving grooves 71 corresponds one-to-one with the position of the n suction heads. The shape of the workpiece receiving groove 71 matches the outer contour shape of the sheet-like irregular workpiece 05. The picking robot 52 is used to pick up the sheet-like irregular workpiece 05 from the flexible vibrating plate 82 and put it into the workpiece receiving groove 71 according to the front and back sides and position information of the sheet-like irregular workpiece 05 determined by the discharge vision module 83.

[0071] In this embodiment, the material conveyor line 6 is a belt drive conveyor line or a chain drive conveyor line. The jig tray 7 is used to hold materials, and the feeding unit 8 is used to realize the automatic discharge, suction, and feeding of sheet-shaped workpieces 05. In use, the discharge bin 81 holds the sheet-shaped workpieces 05. The discharge bin 81 is an existing purchased component that can realize the automatic vibration discharge of sheet-shaped workpieces 05.

[0072] In this embodiment, the structure of the fixture carrier 7 is specifically designed. First, regarding the shape of a single workpiece receiving slot 71, by using a workpiece receiving slot 71 whose shape matches the workpiece shape, the positional accuracy of the workpiece on the fixture carrier 7 can be guaranteed. Furthermore, the workpiece is confined within the workpiece receiving slot 71, ensuring positional accuracy when the workpiece moves between workstations. Second, the arrangement of the workpiece receiving slots 71 is such that the number and spacing of the workpiece receiving slots 71 in each row are completely consistent with the number and spacing of the suction heads in the suction head assembly 51. Thus, when the suction head assembly 51 releases material, after aligning the suction heads with a row of workpiece receiving slots 71, all the suctioned workpieces can be released simultaneously, filling one row of workpiece receiving slots 71 perfectly, greatly improving loading efficiency. Moreover, the workpiece receiving slots 71 are arranged in multiple rows, allowing the fixture carrier 7 to hold a large number of workpieces at once. Each reciprocating motion of the suction head assembly 51 fills one row, until all workpiece receiving slots 71 are filled. This improves the efficiency of the dispensing operation.

[0073] In summary, the automatic dispensing production line of this utility model can ensure the positional accuracy of the workpiece on the fixture carrier 7, that is, ensure the positional accuracy of the workpiece when it flows through each station. Moreover, the design in conjunction with the suction head assembly 51 can improve the overall dispensing efficiency.

After the loading camera 832 is installed on the loading vision mounting frame 831, it can take pictures of the flexible vibrating plate 82, obtain the front and back sides and position information of the workpiece in the flexible vibrating plate 82, and send them to the picking robot 52. The loading camera 832 can also take pictures of the fixture tray 7 located at the loading station 61, obtain the position information of the workpiece receiving groove 71 in the fixture tray 7, and send it to the picking robot 52. According to the position information of the workpiece, the picking robot 52 picks up the workpiece with the colloid receiving groove 051 facing upward and places it in the workpiece receiving groove 71.

[0076] Compared to the structure of mounting a vision camera on the material handling robot 52, in this embodiment, the loading camera 832 is a fixed structure. The material handling robot 52 does not need to be moved above the flexible vibrating plate 82 or the loading station 61 to obtain the position information of the workpiece and the workpiece receiving groove 71 to be loaded in advance, which can improve the efficiency of material handling robot 52 in picking up and loading materials.

[0077] According to a specific embodiment of this utility model, there are two loading stations 61, and the two loading stations 61 are arranged at intervals along the conveying direction of the material conveying line 6; a dispensing station 62 is also provided on the material conveying line 6, and the dispensing unit 9 includes a dispensing machine 91 and a dispensing vision module 92. The dispensing machine 91 is installed on one side of the dispensing station 62, and the dispensing vision module 92 includes: a dispensing vision mounting bracket 921 installed directly above the dispensing station 62, and a dispensing camera 922 installed on the camera mounting bracket. The dispensing machine 91 is used to dispense glue into the glue receiving tank 051 according to the position information obtained by the dispensing vision module 92.

[0078] In this embodiment, since the material handling robot 52 needs to make multiple round trips to load a jig tray 7, two loading stations 61 are set up in conjunction with one dispensing station 62. This avoids waiting, ensures continuous dispensing operations, and further improves dispensing efficiency. The dispensing camera 922 is used to provide the dispensing machine 91 with the position information of the glue receiving tank 051 to be dispensed. Similar to the loading camera 832, the dispensing camera 922 has a fixed structure. It can obtain the position information of the workpiece and the glue receiving tank 051 to be dispensed in advance without the robot arm of the dispensing machine 91 moving it above the dispensing station 62, which can further improve dispensing efficiency.

[0079] According to a specific embodiment of the present invention, the material conveying line 6 passes through the curing unit, and the curing unit includes a drying oven 10 and an air-drying oven 11 arranged sequentially along the conveying direction of the material conveying line 6.

[0080] In this embodiment, the workpiece after dispensing passes through the drying oven 10 and the air drying oven 11 in sequence to achieve rapid curing.

[0081] According to a specific embodiment of this utility model, there are four workpiece bodies 052, which are evenly distributed along the center of the workpiece body 052. The workpiece body 052 is cylindrical in shape. The workpiece body 052 is spaced apart from the side wall of the colloid receiving tank 051. The top surface of the workpiece body 052 is flat. The lower part of the suction rod 520 has four adsorption columns 5201 that correspond one-to-one with the four workpiece bodies 052. The bottom surface of the adsorption column 5201 is flat. Each adsorption column 5201 is provided with an adsorption hole 5202.

[0082] In this embodiment, the shape of the suction rod 520 is set according to the characteristics of the sheet-like irregular workpiece 05. Specifically, since the workpiece body 052 has a convex structure and a flat top surface, a corresponding suction column 5201 with the same structure is set. During adsorption, they correspond one-to-one and the surfaces attract each other, which greatly improves the stability of adsorption.

[0083] It should be noted that the sheet-shaped workpiece 05 can be a rubber button. Rubber buttons are widely used in various electronic products, and their shape matches the shape of the button switch to be used. During use, it is fitted over the button switch to protect it, preventing direct contact with the external environment and thus extending the button's lifespan. Furthermore, the rubber button increases the friction and tactile feel of the button switch, making it easier for users to control and operate electronic products. After the rubber button is molded, adhesive is applied to one side to improve its performance, primarily enhancing tactile feel and durability, improving precision and consistency, and enhancing waterproofing. The outer contour of the sheet-shaped workpiece 05 can be a plum blossom shape, a cloud shape, or other irregular shapes.

[0084] It should also be noted that in this utility model, the material handling vision module, the four-axis horizontal robot, and the slide cylinder 516 can all be directly purchased components. The detailed structure of this utility model is not disclosed in detail, but this does not affect the full disclosure of this utility model. The vision module includes: a camera, a lens, a light source, and an adjustment structure; it is used for positioning and detection at the flexible vibrating plate 82, material handling, and dispensing points.

[0085] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
