[0039] Embodiment 1:

[0040] like Figure 1 The foam 71 automatic bonding device shown includes a machine platform and a transmission module 1, a loading module 2, a bonding module 3, a pressure holding module 4, and a re-inspection module 5 arranged on the machine platform, and its purpose is to bond the foam 71 on the surface of the product 7.

[0041] like Figure 3 As shown, the transmission module 1 is used to transmit the product 7 to be bonded with the foam 71, and includes a streamline track 11, on which a carrier 12 loaded with the product 7 is provided. In this embodiment, four products 7 of the same specification are loaded on each group of carriers 12, and the foams 71a and 71b are located on the front surface of the product 7. The bonding station, the pressure holding station, and the re-inspection station are sequentially arranged on the transmission track corresponding to the bonding module 3, the pressure holding module 4, and the re-inspection module 5, and the carrier 12 is transmitted to each station for processing through the streamline track 11.

[0042] like Figure 4 As shown, a positioning module 6 is also provided at the bottom of the streamline track 11, and the positioning module 6 includes a positioning plate 61 provided below the streamline track 11, and the positioning plate 61 is provided with a lifting mechanism and a lifting support plate 62 provided in the output direction of the lifting mechanism at the position of each workstation, and the lifting mechanism can drive the lifting support plate 62 to move vertically. A positioning pin corresponding to the position of the positioning hole on the carrier 12 is vertically provided on the end surface of the lifting support plate 62, so that the lifting mechanism can drive the lifting support plate 62 to rise and insert the positioning pin into the bottom of the carrier 12, providing vertical support for the carrier 12. Continue to start the lifting mechanism to drive the carrier 12 to leave the streamline track 11, and fix the position of the carrier 12 above each workstation.

[0043] In this embodiment, the lifting mechanism includes a lifting cylinder 63 installed on the positioning plate 61 , and the lifting support plate 62 is connected to the output shaft of the lifting cylinder 63 .

[0044] A blocking cylinder 64 is also provided at the end position of the positioning plate 61 corresponding to each workstation, and the blocking block of the blocking cylinder 64 is connected to the front end surface of the carrier 12. The working principle of the blocking cylinder 64 is the existing technology, and the blocking block can be adjusted to the blocking state and the release state of the carrier 12 according to the stroke of the cylinder. In the blocking state, the position of the carrier 12 is fixed, which facilitates the lifting support plate 62 to rise and dock with the bottom of the carrier 12.

[0045] The feeding module 2 is used to provide the foam 71 for the entire laminating device. The device for providing the foam 71 may adopt the feeder feeding module provided in this embodiment, or may adopt other common foam 71 feeding devices.

[0046] like Figure 5 , Figure 6 As shown, the function of the laminating module 3 is to laminat the foam 71 to the surface of the product 7, including a material transfer robot 31 that absorbs the material from the loading module 2, a visual positioning component 33, and a laminating component 32 connected to the output end of the material transfer robot 31. Since the material transfer robot 31 can independently set the material transfer stroke, two or more laminating stations can be set on the transmission module 1 according to the needs of the entire device, thereby improving the laminating efficiency. When one of the laminating stations cannot be used, the operating speed of the entire assembly line is appropriately reduced, and the remaining laminating stations are relied on to work, so that the entire laminating device does not stop working completely.

[0047] Since the fitting position of the foam 71 is located on the surface of the product 7, a planar four-axis robot is used as the material transfer manipulator 31. The planar four-axis robot has the advantages of high repeatability within a short stroke and high freedom of movement in short-stroke space.

[0048] The bonding component 32 includes a bonding support plate 321 provided at the output end of the planar four-axis robot, a fixed block 322 fixedly connected to the bonding support plate 321, and a movable block 323 slidably connected to the bonding support plate 321. A suction head 324 for adsorbing the foam 71 is installed at the bottom of the movable block 323, and the fixed block 322 and the movable block 323 are connected by a compression spring 325. The suction head 324 absorbs the foam 71 from the feeding module 2 and transfers it to the bonding station on the streamline track 11, and relies on the lifting stroke of the planar four-axis robot to press down to the bonding surface of the product 7. During the entire foam 71 bonding process, the compression spring 325 can provide a buffer for the suction head 324 and apply a gradually increasing bonding force to the product 7.

[0049] The visual positioning component 33 includes a carrier monitoring unit 33a and a correction visual unit 33b. The carrier monitoring unit 33a is connected to the bonding support plate 321, and moves synchronously with the suction head 324 through the bonding support plate 321. Before the suction head 324 sucks the foam 71 from the feeding module 2 or bonds it on the surface of the product 7, the carrier monitoring unit 33a will first locate the position of the foam 71 and the part to be bonded to accurately guide the suction head 324 to suck the foam 71 or bond it. The correction visual unit 33b is set on the side of the feeding module 2, and monitors the suction head 324 and the position of the foam 71 on the suction head 324 to accurately locate the position of the foam 71 on the suction head 324.

[0050] In this embodiment, the carrier monitoring unit 33a and the correction vision unit 33b are both equipped with an industrial camera 331 system, which uses photography to locate and monitor the position of the foam 71 throughout the process, and feeds back the collected information to the control system of the material transfer robot 31 to ensure that the foam 71 can be accurately attached to the surface of the product 7.

[0051] The industrial cameras 331 of the vehicle monitoring unit 33a and the corrected vision unit 33b are illuminated by a ring light source 332 arranged around the industrial cameras 331 to maintain the clarity of the photographs.

[0052] like Figure 7 As shown, the pressure-maintaining module 4 arranged at the pressure-maintaining station includes a pressure-maintaining support plate 41 that moves in the vertical direction and pressure blocks 43 that are evenly arranged at the bottom of the pressure-maintaining support plate 41, and a rubber-wrapped pressure head that presses the foam 71 on the surface of the product 7 is arranged at the end of the pressure block 43 to simultaneously press the four groups of products 7 on the carrier 12 in the vertical direction.

[0053] The function of the pressure-maintaining module 4 is to maintain pressure on the fitting position of the product 7 in the carrier 12 for a certain period of time to prevent the foam 71 from falling off the surface of the product 7. In this embodiment, the pressure-maintaining support plate 41 is driven to move by a pressure-maintaining linear module 42 vertically arranged on the side of the streamline track 11.

[0054] The pressure block 43 is slidably connected to the pressure-maintaining support plate 41 through a linear bearing, and a counterweight block is set at the end of each linear bearing. The holding pressure is transmitted to the pressure head and foam 71 by the weight of the counterweight block itself, and the size of the holding pressure can be changed by increasing or decreasing the weight of the counterweight block.

[0055] like Fig.12As shown, the re-inspection module 5 is located at the end of the streamline track 11, and re-inspects the bonding surface of the product 7 after pressure holding, and includes a re-inspection detection unit 51 formed by an industrial camera 331 and a ring light source 332. The re-inspection detection unit 51 is connected to an X-axis re-inspection module 53 arranged along the transmission direction of the product 7 through a re-inspection support plate 52, and the X-axis re-inspection module 53 is installed on a Y-axis re-inspection module 54 arranged perpendicular to the transmission direction of the product 7. The re-inspection detection unit 51 is driven by the X-axis re-inspection module 53 and the Y-axis re-inspection module 54 to realize one by one confirmation of the bonding parts of the four groups of products 7 at the re-inspection station.

[0056] Embodiment 2:

[0057] like Figure 8 Another embodiment of the utility model is shown, which also has a machine and a transmission module 1, a feeding module 2, a positioning module 6, a laminating module 3, a pressure holding module 4, and a re-inspection module 5 arranged on the machine, and the functions of each module are substantially the same. The difference from the first embodiment is that the laminating position of the foam 71c is located in the side direction of the product 7, with a certain inclination angle, so the specific structure of each module is adjusted accordingly.

[0058] like Fig. 9 and Fig.10 As shown, in the laminating module 3, the material transfer manipulator 31 is a six-axis robot, and the laminating assembly 32 is connected to the action end of the six-axis robot through a laminating support plate 321. The laminating assembly 32 is also arranged in two groups along the streamline track 11, and two rubber heads are arranged on each group of laminating assembly 32 corresponding to the position of the product 7, so that each group of laminating assembly 32 only needs to execute power once to complete the laminating of the foam 71.

[0059] In the visual positioning component 33, the carrier monitoring unit 33a used to locate the part to be bonded on the bonding station is arranged on the side of the streamline track 11 and a monitoring angle is set for the bonding part. The visual positioning component 33 also includes a monitoring linear module that drives the carrier monitoring unit 33a to move, driving the carrier monitoring unit 33a to visually monitor the products 7 in the carrier 12 one by one. The monitoring linear module includes a Y-axis monitoring module 334 arranged along the vertical transmission direction of the carrier 12 and an X-axis monitoring module 333 arranged along the streamline track 11, wherein the Y-axis monitoring module 334 is connected to the X-axis monitoring module 333, and the carrier monitoring unit 33a is connected to the Y-axis monitoring module 334, relying on the X-axis monitoring module 333 and the Y-axis monitoring module 334 to achieve four-axis movement in the horizontal plane.

[0060] The corrective visual unit 33b for locating the position of the bonding component 32 on the material transfer robot 31 is set on the side of the streamline track 11 and is set at an inclination angle toward the bonding position. Before the bonding component 32 is bonded to the foam 71, the position of the foam 71 on the material transfer robot 31 is confirmed by taking a photo through the corrective visual unit 33b and the angle of the material transfer robot 31 is fine-tuned according to the confirmation result, so that the foam 71 is accurately bonded to the surface of the product 7.

[0061] like Fig.11 As shown, in the pressure-maintaining module 4, four groups of pressure blocks 43 are each slidably connected to the pressure-maintaining support plate 41 through a group of cylinders, and the sliding direction of the pressure blocks 43 is the same as the tilting direction of the foam 71 on the product 7. One action of the cylinder simultaneously maintains the pressure of the four groups of products 7 on the carrier 12.

[0062] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
