Detailed Implementation

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] Example 1

[0031] A specific embodiment of this utility model is as follows: Figure 1 As shown, an automatic injection device for honeycomb cavities is disclosed, including a three-dimensional scanning module 1, a gantry robot module 2, a rotating base 3, a track moving structure 4, a single-hole injection module 5, and an overall injection module 6.

[0032] The truss robot module 2 includes a truss and a walking robot capable of reciprocating on the truss; a 3D scanning module 1 is mounted on the truss and used to scan the honeycomb cavities that need to be filled; a rotating base 3 is located below the truss, can rotate around its own axis, and can also reciprocate along the track moving structure 4. The walking robot can be selectively connected to the integral compact structure of the single-hole filling module 5 or the integral filling module 6 to facilitate automatic filling of the honeycomb cavities of arc-shaped or circular plate-shaped honeycomb products.

[0033] For details, see Figure 1 The truss consists of four vertically supporting beams, two horizontally arranged transverse beams, and two longitudinal beams. The vertical beams are bolted to the ground. The ends of the transverse beams are each fixed to the top of one of the vertical beams. The longitudinal beams are mounted on the transverse beams and can reciprocate along them. The walking robot is mounted on the longitudinal beams and can reciprocate along them. This configuration allows the walking robot to move freely within the truss's range.

[0034] In the preferred embodiment, four longitudinal beams are provided, corresponding to two walking robots. This configuration allows two walking robots to work simultaneously, further improving production efficiency.

[0035] The walking robot features a first quick-change connector, suitable for rapidly grasping the integral pressing structure of either the single-hole injection module 5 or the overall injection module 6. The first quick-change connector can utilize a conventional structure found in the mechanical equipment field.

[0036] The truss robot module 2 provides support and positioning for the single-hole injection module 5, the scanner 11, and the overall compaction structure 68, and is automatically controlled by the central control system.

[0037] The track-moving structure 4 includes a track fixed to the ground and a slider mounted on the track. The first end of the track is adjacent to the product lifting and unloading point, and the second end extends to the underside of the truss.

[0038] The rotating base 3 is rotatably mounted on the slider, allowing it to reciprocate along the track and rotate around its own axis. The rotating base 3 is used to secure the honeycomb product to be filled. During operation, the rotating base 3 first moves to the first end of the track, loads and secures the product at the product lifting / unloading point, and then moves to the second end of the track for the filling operation.

[0039] Rotating base 3 is used to support, for example Figure 6The arc-shaped and circular plate-shaped honeycomb products shown feature low rotation speed and high precision, enabling them to be used in conjunction with other automated equipment for automatic filling operations. The track-moving structure 4 is used to transfer products. When a product needs processing, the track-moving structure 4 drives the rotating base 3 to the product unloading area, loads and secures the product, and then moves it to the center of the gantry robot module 2 for filling operations.

[0040] See Figure 1 , Figure 5 The 3D scanning module 1 includes a scanner module 11 and a matching tracker. The 3D scanning module 1 is used to construct a 3D model of the cellular network, digitize the product data, and store the scanned model data into the central control system to provide data information for subsequent automated control.

[0041] See Figure 2 The single-hole filling module 5 includes a quick-change assembly 54, a first stirring assembly, and a discharge filling assembly. The first stirring assembly and the discharge filling assembly are mounted on the walking robot via the quick-change assembly 54. The quick-change assembly 54 includes a second quick-change connector adapted to engage with the first quick-change connector. The quick-change assembly 54 also includes a support frame for fixing the first stirring assembly.

[0042] The first mixing assembly includes a first feed inlet 51, a first variable frequency motor 52, and a first mixing drum 53. Material enters the first mixing drum 53 through the first feed inlet 51, and the first variable frequency motor 52 drives the mixing elements within the first mixing drum 53 to mix the material. The first mixing drum 53 is fixedly mounted within a support frame on one side of the quick-change assembly 54. The entire first mixing assembly is made of stainless steel and has an anti-stick coating to prevent material from adhering to the inner wall. The volume of the first mixing drum 53 is preferably 60L.

[0043] The material discharging and filling assembly includes a C-axis rotary motor 55, an R-axis oscillating motor 56, a first discharging and weighing unit 57, and a filling unit 58. The C-axis rotary motor 55 is fixedly mounted below the quick-change assembly 54 and drives the material discharging and filling assembly to rotate around the C-axis, which is the central axis of the filling unit 58. The R-axis oscillating motor 56 is positioned between the C-axis rotary motor 55 and the filling unit 58 and drives the filling unit 58 to oscillate around the horizontal R-axis. The first discharging and weighing unit 57 is located below the first stirring drum 53, with its inlet connected to the first stirring drum 53 and its outlet connected to the filling unit 58. The bottom of the filling unit 58 has a filling port for injecting material into the honeycomb cavity. The weight of the filler is calculated using data from each single hole obtained by the 3D scanning module 1. An appropriate amount of material is weighed for each single hole, and the filling unit 58 performs adaptive filling of the honeycomb pores, enabling the material to fill each single hole and improving the filling efficiency of each single hole.

[0044] The single-hole injection module 5 is suitable for injection operations on arc-shaped products.

[0045] See Figure 1 , Figures 3-4 In addition to the integral pressing structure 68, the integral filling module 6 also includes a second mixing component and a discharge blanking component. The second mixing component and the discharge blanking component are fixedly mounted on the ground, located on one side of the rotating base 3 and the track moving structure 4. They are used to mix the material evenly, weigh it, and then transport the material into blanks before placing them above the rotating base 3. The integral pressing structure 68 is connected to the first quick-connect coupling of the walking robot, and is used to press the blanks placed on the honeycomb product to be filled, which is fixed on the rotating base 3, into the honeycomb holes of the product.

[0046] Specifically, the second mixing assembly includes a second feed inlet, a second mixing drum 61, and a second mixing frequency conversion motor 62. The discharge and blanking assembly includes a second discharge and weighing unit 63, a blanking unit 64, and a telescopic belt conveyor 65. The entire second mixing assembly is made of stainless steel and has an anti-stick coating to prevent materials from sticking to the inner wall. The volume of the second mixing drum 61 is preferably 300L.

[0047] The second discharge and weighing unit 63 is located below the second mixing drum 61, with its inlet connected to the second mixing drum 61 and its outlet connected to the billet-making unit 64. The billet-making unit 64 is used for rapid production of billets and can control the uniformity of the billets. The billet-making unit 64 includes a servo electric cylinder, which can precisely control the stroke of the servo to control the size of the billets. A telescopic belt conveyor 65 is located at the outlet of the billet-making unit 64. After the billets are pressed, they are conveyed onto the telescopic belt conveyor 65, which transports them above the rotating base 3. The telescopic belt conveyor 65 can freely extend and retract along its length, reaching up to the center of the rotating base 3, assisting operators in placing the billets on the honeycomb products to be filled.

[0048] See Figure 4 The integral billet pressing structure 68 includes a third quick-connect coupling, a pressure column, and a pressure plate. The third quick-connect coupling is located at the top of the pressure column and is used to connect with the first quick-connect coupling. The pressure plate is located at the bottom of the pressure column and is used to press the billet into the honeycomb cells. The integral billet pressing structure 68 uses a walking robot on a truss to provide pressure to press the billet into the honeycomb cells of the product, which can quickly complete the operation of pressing a large number of billets into the honeycomb cells.

[0049] The integral injection module 6 is suitable for injection operations of round plate-shaped products.

[0050] Compared with the prior art, the automatic cell filling device provided in this embodiment automatically identifies the cell product data through three-dimensional scanning and then processes the data to calculate various data of each cell, such as mechanical coordinates, center point coordinates, height and cell grid cross-sectional area. The system controls the single-cell filling module to perform filling operation on each cell or the overall filling module to perform filling operation on multiple cells at the same time based on the data.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
