Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit production, and in particular to a rotary pre-laminating device. Background Art

[0002] One structure of an integrated circuit is a multi-layer board, for example, a structure formed by covering the upper and lower surfaces of a core board provided with an integrated circuit with PP sheets respectively. This multi-layer board structure can effectively isolate the integrated circuit from the outside world, thereby making the working environment of the integrated circuit more stable.

[0003] In the preparation of a multi-layer board, it is necessary to pre-laminate a first PP sheet, a core board, and a second PP sheet in sequence to form a pre-laminated structure, and then transfer it to the next station for processing. The current pre-laminating method usually uses multiple manipulators in cooperation with a pre-laminating combination table. For details, reference can be made to Chinese patents with patent numbers CN202110852558, CN202120528184.4, etc. Only one pre-laminated structure can be formed on a pre-laminating combination table at a time, resulting in very low efficiency. Summary of the Invention

[0004] The present invention provides a rotary pre-laminating device for the problems of the prior art, which can improve the efficiency of pre-laminating.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A rotary pre-laminating device provided by the present invention includes a first feeding mechanism, a second feeding mechanism, a third feeding mechanism, a material transfer mechanism, and a rotary table mechanism. The rotary table mechanism is provided with a plurality of fixed modules for accommodating materials. The first feeding mechanism, the second feeding mechanism, the third feeding mechanism, and the material transfer mechanism are arranged in sequence along the rotation direction of the rotary table mechanism. The first feeding mechanism is used to feed a first PP sheet into the fixed module, the second feeding mechanism is used to feed a core board onto the first PP sheet in the fixed module, the third feeding mechanism is used to feed a second PP sheet onto the core board in the fixed module. The first PP sheet, the core board, and the second PP sheet are stacked in sequence to form a pre-laminated structure, and the material transfer mechanism is used to transfer the pre-laminated structure to the outside.

[0007] Further, the fixed module includes a base and a plurality of pressing components, both of which are arranged on the rotating disk. The base has a receiving groove for accommodating materials, and the pressing components are used to press the materials in the receiving groove to fix them in the receiving groove.

[0008] Furthermore, the pressing component includes a pressing cylinder and a pressing piece. The pressing cylinder is installed on the rotating disk, and the pressing piece is installed on the piston of the pressing cylinder.

[0009] Further, the first feeding mechanism includes a first bin, a first transfer module, a first positioning module, and a first feeding robot. The first bin is used to store the first PP sheets. The first transfer module is used to transfer the first PP sheets in the first bin to the first positioning module. The first positioning module is used to identify the position and posture of the first PP sheets. The first feeding robot is used to transfer the first PP sheets to the fixing module according to the recognition result of the first positioning module.

[0010] Furthermore, the first positioning module identifies the first PP sheets by means of vision.

[0011] Further, the second feeding mechanism includes a second bin, a second transfer module, a second positioning module, and a second feeding robot. The second bin is used to store the core boards. The second transfer module is used to transfer the core boards in the second bin to the second positioning module. The second positioning module is used to identify the position and posture of the core boards. The second feeding robot is used to transfer the core boards to the fixing module according to the recognition result of the second positioning module.

[0012] Furthermore, the second feeding mechanism further includes a code scanning device, which is used to obtain the identification code on the core board.

[0013] Further, the material transfer mechanism includes a material transfer module, a turntable, and a rotation module. The material transfer module is used to transfer the pre-stack structure to the turntable. The rotation module is used to drive the pre-stack structure in the turntable to rotate to adjust the posture.

[0014] Advantages of the present invention: The present invention replaces the traditional combined table for pre-stacking with a turntable mechanism. By using the turntable mechanism, the fixing module passes through the first feeding mechanism, the second feeding mechanism, the third feeding mechanism, and the material transfer mechanism one by one, so as to achieve the effect of synchronous movement of multiple mechanisms, and further improve the efficiency of pre-stacking.

Detailed implementation mode

[0018] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation mode does not limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0019] As Figure 1 and Figure 2 shown, a turntable type pre-stack device provided by the present invention includes a first loading mechanism 1, a second loading mechanism 2, a third loading mechanism 3, a material transfer mechanism 4 and a turntable mechanism 5. The turntable mechanism 5 is provided with a plurality of fixing modules 53 for accommodating materials. The first loading mechanism 1, the second loading mechanism 2, the third loading mechanism 3 and the material transfer mechanism 4 are arranged in sequence along the rotation direction of the turntable mechanism 5. The first loading mechanism 1 is used to load the first PP sheet into the fixing module 53. The second loading mechanism 2 is used to load the core board onto the first PP sheet in the fixing module 53. The third loading mechanism 3 is used to load the second PP sheet onto the core board in the fixing module 53. The first PP sheet, the core board and the second PP sheet are stacked in sequence to form a pre-stack structure. The material transfer mechanism 4 is used to transfer the pre-stack structure to the outside.

[0020] In the prior art, only a pre-stack combination table as mentioned in the prior art is used, or a structure with dual-platform switching is adopted, such as the loading structure disclosed in the patent with the patent number CN202311830284.2. No matter which method is used, the effect of enabling the first loading mechanism 1, the second loading mechanism 2, the third loading mechanism 3 and the material transfer mechanism 4 to execute actions simultaneously cannot be achieved, so the efficiency is not high.

[0021] In actual use, the turntable mechanism 5 includes a rotating disk 51 and a turntable driving module 52. The turntable driving module 52 is used to drive the rotating disk 51 to rotate. A number of fixed modules 53 are distributed in a circular array on the rotating disk 51 with the center of the rotating disk 51 as the center of the circle. The fixed modules 53 are used to accommodate the pre-stacked materials. Specifically, the number of the fixed modules 53 is preferably four, corresponding to the first feeding mechanism 1, the second feeding mechanism 2, the third feeding mechanism 3, the material transfer mechanism 4, and the turntable mechanism 5 respectively.

[0022] Using the turntable mechanism 5 to realize the transmission of materials, in addition to improving efficiency, since the turntable driving module 52 is located at the bottom of the rotating disk 51, it effectively ensures that debris, dust, etc. will not float between the upper and lower parts of the rotating disk 51, ensuring that the oil, debris, etc. that may be generated during the operation of the turntable driving module 52 will not fall on the fixed module 53 of the rotating disk 51, thus ensuring cleanliness.

[0023] Based on the above problems, the present invention first uses the turntable mechanism 5 to replace the traditional combined table structure, and uses the turntable mechanism 5 to realize the simultaneous movement of multiple stations, so that the first feeding mechanism 1, the second feeding mechanism 2, the third feeding mechanism 3, and the material transfer mechanism 4 can perform corresponding actions at different stations simultaneously, making the pre-stacking action change from a cycle of 20 seconds to a cycle of 8 seconds, greatly improving the efficiency.

[0024] In this embodiment, the fixed module 53 includes a base 531 and a plurality of pressing components 532 that are both arranged on the rotating disk 51. The base 531 has a receiving groove 535 for accommodating materials, and the pressing components 532 are used to press the materials in the receiving groove 535 to fix them in the receiving groove 535.

[0025] That is, the receiving groove 535 of the base 531 is used to accommodate the first PP, the core board, and the second PP, so that the three are pre-stacked in the receiving groove 535 in sequence, ensuring the accuracy of the position. The pressing components 532 are used to press each material after one material is fed, so as to ensure that the relative positions of different materials in the receiving groove 535 will not change when the rotating disk 51 rotates.

[0026] Specifically, the pressing component 532 includes a pressing cylinder 533 and a pressing piece 534. The pressing cylinder 533 is installed on the rotating disk 51, and the pressing piece 534 is installed on the piston rod of the pressing cylinder 533. The pressing of the materials is realized by the cooperation of the pressing cylinder 533 and the pressing piece 534. The structure is simple and easy to implement, and the pressing effect is also ensured. Preferably, the number of the pressing components 532 is not less than three, and the not less than three pressing components 532 are located on the periphery of the base 531, respectively used to press different positions of the materials.

[0027] Specifically, the pressing cylinder 533 is a rotary cylinder. After the pressing cylinder 533 controls the lifting of the pressing member 534, the pressing member 534 will rotate to a position not directly above the receiving groove 535, so as to avoid interfering with the feeding of the material.

[0028] In this embodiment, the first feeding mechanism 1 includes a first material bin 11, a first transfer module 12, a first positioning module 13, and a first feeding robot 14. The first material bin 11 is used to store the first PP sheet. The first transfer module 12 is used to transfer the first PP sheet in the first material bin 11 to the first positioning module 13. The first positioning module 13 is used to identify the position and posture of the first PP sheet. The first feeding robot 14 is used to transfer the first PP sheet to the fixing module 53 according to the identification result of the first positioning module 13.

[0029] Specifically, the first material bin 11 and the first transfer module 12 are conventional mechanisms for PP sheets and will not be elaborated here. After the first PP sheet is transferred from the material bin to a specific position of the first transfer module 12, the first positioning module 13 positions the first PP sheet, specifically by identifying the coordinate position and posture of the first PP sheet. Then, the first feeding robot 14 performs positioning and picking according to the position of the first PP sheet, and performs horizontal rotation according to the posture of the first PP sheet, so that the first PP sheet is transferred to the fixing module 53 in the required posture, and then is fixedly pressed by the pressing component 532 in the fixing module 53 to ensure that the posture of the first PP sheet does not change relative to the rotating disk 51 during the rotation of the rotating disk 51.

[0030] The specific structure of the third feeding mechanism 3 is similar to that of the first feeding mechanism 1 and will not be elaborated here.

[0031] Specifically, the first positioning module 13 identifies the first PP sheet by visual means. That is, the first positioning module 13 is preferably an industrial camera or other high-precision identification device, which is used to identify the first PP sheet transferred to a specific position (such as the end) of the first transfer module 12, so as to send the identification result to the first robot, and the first robot accurately picks up the first PP sheet and adjusts it to a suitable posture.

[0032] In this embodiment, the second feeding mechanism 2 includes a second material bin 21, a second transfer module 22, a second positioning module 23, and a second feeding robot 24. The second material bin 21 is used to store the core board. The second transfer module 22 is used to transfer the core board in the second material bin 21 to the second positioning module 23. The second positioning module 23 is used to identify the position and posture of the core board. The second feeding robot 24 is used to transfer the core board to the fixing module 53 according to the identification result of the second positioning module 23. Specifically, the second feeding mechanism 2 further includes a scanning device, and the scanning device is used to obtain the identification code on the core board.

[0033] The second loading mechanism 2 is used to load the core board, that is, the material with integrated circuits. In order to ensure traceability, each core board is equipped with a unique identification code for identity recognition. When loading the core board, the second transfer module 22 transfers the core board from the second bin 21 to a specific position, and then the code scanning device scans and identifies the identity information of the core board during the transfer process / at a specific position and enters it. Then, the second positioning module 23 identifies the specific coordinate position and posture of the core board. The identification method can be achieved by using specific features of the core board as the identification points. After identifying the coordinate position and posture of the core board, the second loading robot 24 picks up the core board and places it into the fixing module 53 containing the first PP sheet, and ensures that the core board and the first PP sheet are stacked in the required posture. Subsequently, the fixing module 53 presses the two in the current posture into the accommodation groove 535, so that they will not move relative to each other when the rotating disk 51 rotates, ensuring the accuracy of pre-stacking.

[0034] In this embodiment, the material transfer mechanism 4 includes a material transfer module 41, a transfer table 42, and a rotation module 43. The material transfer module 41 is used to transfer the pre-stacked structure to the transfer table 42, and the rotation module 43 is used to drive the pre-stacked structure in the transfer table 42 to rotate to adjust the posture.

[0035] That is, the pre-stacked structure is transferred from the material transfer module 41 to the transfer table 42, and then, according to the needs of subsequent processes, it is decided whether to rotate the pre-stacked structure horizontally by 180°. This rotation is controlled and achieved by the rotation module 43. Subsequently, an external manipulator transfers the pre-stacked structure on the transfer table 42 to the reflow line 44, and all the actions of the present invention can be completed.

[0036] For the sake of easy understanding, the main action steps of the present invention are described again here:

[0037] A. The first PP sheet is transferred from the first bin 11 to the first specific position through the first transfer module 12. Then, the first positioning module 13 takes an image of the first PP sheet and obtains the position and posture of the first PP sheet from the image. Then, the first loading robot 14 picks up the first PP sheet according to the position and posture of the first PP sheet and adjusts it to the required posture and places it into the accommodation groove 535.

[0038] B. After the pressing mechanism presses the first PP sheet, the rotating disk 51 rotates, so that the accommodation groove 535 with the first PP sheet is transferred to the second loading mechanism 2; then the pressing mechanism releases the first PP sheet.

[0039] C. The core board is transported from the second bin 21 to the second specific position through the second transport module 22. Then, the imaging device acquires the image of the core board and extracts the identification code from the image. Next, the second positioning module 23 acquires the position and attitude of the core board. Specifically, the operation of the first positioning module 13 can be referred to. Then, the second loading robot 24 picks up the core board, adjusts its attitude, and places it into the receiving groove 535, so that the core board contacts the first PP sheet with the required relative attitude.

[0040] D. The pressing mechanism presses the core board until it stably abuts against the first PP sheet. Then, the rotating disk 51 rotates to move the receiving groove 535 with the first PP sheet and the core board to the second loading mechanism 2. Then, the pressing mechanism releases the core board.

[0041] E. The third loading mechanism 3 operates to form a pre-stack structure in the receiving groove 535. Specifically, the operation of the third loading mechanism 3 refers to step A.

[0042] F. After the pressing mechanism presses the pre-stack structure, the rotating disk 51 rotates to move the receiving groove 535 with the pre-stack structure to the material transfer mechanism 4. Then, the pressing mechanism releases the pre-stack structure.

[0043] G. The material transfer mechanism 4 removes the pre-stack structure from the receiving groove 535.

[0044] H. The rotating disk 51 rotates to move the empty receiving groove 535 to the first loading mechanism 1.

[0045] Among them, steps A / C / E / G are executed on different receiving grooves 535 simultaneously.

[0046] As mentioned above, it is only a preferred embodiment of the present invention, and there is no any form of limitation to the present invention. Although the present invention is disclosed as the above preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the technical solution scope of the present invention, when making some changes or modifications using the above-disclosed technical content to equivalent embodiments of equivalent changes, but as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
