[0031] As Figure 1 The utility model discloses a kind of automatic foam pasting equipment, including: rack 1, be set on rack 1 and be used for conveying and transporting the conveying assembly 2 of product to be pasted, be set on conveying assembly 2 one side, for installing the adsorption assembly 23 of foam raw material 31 bearing plate 30, be set on rack 1 and be used for grabbing foam raw material 31 on adsorption assembly 23, and pasting to the multi-degree-of-freedom manipulator 24 of product, the conveying assembly 2 is laid out with two columns on rack 1, and the transmission direction of two columns conveying assembly 2 is opposite in same time, to form double station for multi-degree-of-freedom manipulator 24 operation on rack 1;Wherein, the multi-degree-of-freedom manipulator 24 is located above adsorption assembly 23 and conveying assembly 2.

[0032] Working principle:

[0033] The operator places the product MIC plate 32 to be pasted on at least two rows of conveying tracks of the conveying assembly 2, and the conveying assembly 2 starts to work. Since it has double stations, it can carry two or more products to be processed at the same time, realize parallel operation, and greatly improve the work efficiency. The conveying assembly 2 accurately and stably transports the product to be pasted along the set track to the designated pasting position. During the transportation process, the speed and position accuracy of the conveying assembly 2 can be flexibly adjusted by the control end 27 according to the actual production needs. At the same time, the operator installs the foam raw material 31 carrying plate 30 on the adsorption assembly 23. When the product to be pasted reaches the predetermined position, the multi-degree-of-freedom manipulator 24 starts to work. The multi-degree-of-freedom manipulator 24 is accurately controlled by the control end 27, and can quickly and accurately grab the foam raw material 31 from the adsorption assembly 23 according to the preset motion path and action instruction. The manipulator realizes accurate grabbing, posture adjustment and spatial position movement of the foam raw material 31 by virtue of its multiple movable joints. Then, the manipulator accurately pastes the foam raw material 31 to the designated position of the product. After the product on one row of conveying assemblies 2 is pasted with foam, the products on this row can be quickly unloaded and then new products to be pasted are loaded. By utilizing the time difference between the two stations, the products on the other row of conveying assemblies 2 are conveyed inward and are ready for foam pasting operation. Through this double-station alternating cycle mode, the equipment can continuously and efficiently work, greatly improving the overall production efficiency of foam pasting.

[0034] In the above technical solution, it further comprises an industrial camera I 25 arranged at the moving end of the multi-degree-of-freedom manipulator 24, and an industrial camera II 26 arranged at one side of the adsorption assembly 23.

[0035] The industrial camera I 25 and the industrial camera II 26 are oppositely oriented in space, the industrial camera II 26 is located below the multi-degree-of-freedom manipulator 24 in space, and the industrial camera I 25 and the industrial camera II 26 are in communication connection with the control end 27 on the rack 1. With this technical solution, the industrial camera I 25 first takes a photo of the product MIC plate 32 to be pasted as a whole and uploads it to the control end 27 for analysis, and plans the subsequent pasting path of the manipulator. At the same time, the manipulator moves above the adsorption assembly 23, the industrial camera I 25 takes a photo of the foam raw material 31 carrying plate 30 and uploads it to the control end 27 for analysis, and plans the adsorption path of the manipulator to the foam raw material 31. After the adsorption of the manipulator is completed, it moves above the industrial camera II 26, takes a photo and uploads it, and identifies the foam position correction through the manipulator.

[0036] In the above technical solution, the conveying assembly 2 comprises: a support plate 21 for mounting and fixing the product to be applied, a driving component 22 for moving the support plate 21 from the working position to the unloading position, and the driving component 22 is arranged at the bottom of the support plate 21. With this technical solution, the support plate 21 serves as a carrier for mounting and fixing the product to be applied, providing a stable support surface for the product and ensuring that the product maintains a fixed position and posture during the conveying process. The driving component 22 is arranged at the bottom of the support plate 21, which can accurately control the moving distance, speed and start-stop of the support plate 21, thereby achieving accurate conveying of the product to be applied.

[0037] In the above technical solution, the support plate 21 is provided with a recess I 211 consistent with the shape of the product to be applied, and the recess I 211 is provided with a fixing member 29 of the MIC plate around it, which is spatially matched with the product to be applied. With this technical solution, the recess I 211 is consistent with the shape of the product to be applied, and after the product is placed in the recess I 211, it can be tightly fitted, with the edges of the product precisely matched with the corresponding edges of the recess I 211, and the internal shape of the recess I 211 can avoid the electronic integrated components on the back of the MIC plate. This precisely defines the position of the product on the support plate 21, reducing the positional deviation caused by shaking and deviation of the product during the conveying process, and providing a foundation guarantee for the subsequent precise application of foam.

[0038] In the above technical solution, the suction assembly 23 comprises: a fixed disc I 231 spatially matched with the foam raw material 31 carrying plate 30, a fixed disc II 232 with a recess II 2321, and the recess II 2321 of the fixed disc I 231 and the fixed disc II 232 are matched to form a hollow structure in space, and a plurality of through holes I 233 are uniformly arranged on the fixed disc I 231 and are in communication with the inside;

[0039] The external vacuum source is communicated with the inside through a plurality of through holes 2234 formed in the bottom of the fixed disc II 232. The fixed disc I 231 is fixedly connected with the rack 1 through a mounting member arranged at the bottom. A sealing member 33 is arranged at the joint of the fixed disc I 231 and the fixed disc II 232. According to the technical scheme, when the vacuum adsorption carrier of the foam raw material 31 is needed, the plurality of foam raw materials 31 are first placed on the bearing plate 30. Since the bearing plate 30 is located outside the fixed disc I 231, the placement position needs to be ensured to be accurate. Then, the external vacuum source is started. Since the grooves 22321 of the fixed disc I 231 and the fixed disc II 232 are matched, a hollow structure is formed in space. After the external vacuum source is started, the air in the hollow structure is rapidly extracted through the plurality of through holes 2234 formed in the lower surface of the fixed disc II 232. The plurality of through holes 2234 of the fixed disc II 232 increase the air inlet area, so that the air extraction process is efficient and stable, and the air pressure in the hollow structure can be reduced in a short time to form a negative pressure environment. The sealing member 33 is arranged on the contact surface of the fixed disc I 231 and the fixed disc II 232.

[0040] After the negative pressure is formed in the hollow structure, because the plurality of through holes 1233 that are in communication with the inside of the hollow structure are uniformly formed in the fixed disc I 231, the pressure difference causes the air to flow from above the bearing plate 30 to the inside of the hollow structure through the through holes 1233. According to Bernoulli's principle, the place with a high flow rate has a small pressure. The relatively high air pressure above the bearing plate 30 tightly presses the bearing plate 30 to the fixed disc I, thereby realizing the adsorption and fixation of the bearing plate 30.

[0041] In the above technical scheme, a plurality of telescopic material taking clamps 241 are arranged at the moving end of the multi-degree-of-freedom manipulator 24. The material taking clamp 241 is configured as a suction cup 242. According to the technical scheme, the plurality of telescopic material taking clamps 241 can realize the one-time taking of a plurality of foams by the manipulator. The industrial camera II 26 separately photographs the foams on each material taking clamp 241. In the pasting process, the skew angle of each foam is adjusted separately. Meanwhile, the telescopic material taking clamp 241 separately pastes the position to be pasted on the MIC plate, without affecting the pasting work of other material taking clamps 241. The material taking clamp 241 is configured as a suction cup 242, and the structure is relatively simple, so that the suction cup 242 can stably work for a long time. After the pasting is completed, each suction cup 242 blows air outward to blow off the protective film 32 of each foam raw material, without the need for manual cleaning.

[0042] In the above technical solution, the driving component 22 comprises: a rodless cylinder 221 arranged along the conveying direction of the product, the moving end of the rodless cylinder 221 is fixedly connected with the support plate 21 through a connecting piece, and further comprises: a guide rail 222 spatially matched with the rodless cylinder 221, and the connecting piece is fixedly connected with a sliding block on the guide rail 222. With this technical solution, when the equipment starts to operate, the control end 27 controls the rodless cylinder 221 to start working according to the production process requirements. The moving end of the rodless cylinder 221 starts to move under the driving of the air pressure, and drives the connecting piece to move. The connecting piece drives the sliding block fixedly connected thereto to move along the guide rail 222, and since the support plate 21 is fixedly connected with the connecting piece, the support plate 21 moves linearly along the guide rail 222 (i.e. the conveying direction of the product). During the movement of the support plate 21 from the working position to the feeding position, the rodless cylinder 221 continuously provides power, and the guide rail 222 and the sliding block ensure the accuracy and stability of the movement, so that the product to be pasted on the support plate 21 can be safely and accurately conveyed to the designated position. After completing a conveying task, the entire driving component 22 will repeat the above process according to the instruction of the control end 27, and return the support plate 21 from the feeding position to the working position, or continue to convey new products to the working position, so as to realize the circulation work and cooperate with the automatic production process of the entire foam automatic pasting equipment.

[0043] In the above technical solution, the rack 1 is provided with a plurality of Forma wheels 28 at the bottom. With this technical solution, the Forma wheels 28 have good rolling performance, so that the entire foam automatic pasting equipment can easily move on the plane. When it is necessary to adjust the position of the equipment, the operator can push the equipment to make the Forma wheels 28 roll, so as to realize the rapid translation of the equipment. This is very convenient when the workshop layout is adjusted, the equipment is cleaned or maintained, and the trouble of using large lifting equipment to move the equipment is avoided. At the same time, the self-locking brake function of the Forma wheels 28 can firmly lock the equipment at a specific position, so as to prevent the equipment from moving accidentally due to external interference during operation. The support rod on one side of the Forma wheels 28 can lift and fix the equipment after the equipment is fixed.

[0044] Although the embodiments of the present application have been disclosed as above, they are not limited to the application and implementation described in the specification and examples, and can be fully applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, and therefore the present application is not limited to specific details and the figures shown and described herein.
