Description

TECHNICAL FIELD

[0001] The present application relates to the field of watch glass film detection, in particular to a watch glass module film and detection device. BACKGROUND

[0002] At present, in the production process of watch glass module, the film and detection link mostly rely on manual operation, which has many defects that are difficult to overcome. In terms of detection, manual detection requires the operator to wear gloves and hold the glass module in bright light and carefully observe with the eyes. Long time in strong light environment, the operator's eyes are prone to dryness, fatigue, vision decline and other problems, which seriously affect the health. Moreover, the efficiency of manual detection is low, which is greatly affected by the experience, state and emotion of the operator, and the detection quality is unstable, often missing and misjudging, resulting in unqualified products flowing into the market, causing a large number of complaints, increasing the cost and reputation loss of enterprises.

[0003] In terms of film, the same mode of manual wearing gloves and holding glass module in bright light environment is adopted, which not only has extremely low efficiency and cannot meet the needs of large-scale production, but also cannot guarantee the quality of film. When manually pasting the film, due to uneven hand strength control, non-standard operation method and other reasons, a large number of bubbles are easily generated between the film and the glass surface, affecting the appearance and performance of the product. At the same time, manual film pasting can not guarantee the accurate position of the film, and often causes deviation, resulting in the need for multiple film pasting operations, which will leave residual glue on the product surface, increase material waste and production cost, and affect the subsequent process and the final quality of the product. In addition, during manual operation, the glass module is easily damaged due to hand shaking, collision and other reasons, further increasing the production cost.

[0004] These problems seriously restrict the automation level and production efficiency of watch glass module production, and cannot meet the development needs of modern manufacturing industry with high quality and high efficiency.

DETAILED DESCRIPTION

[0047] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0048] Reference Figures 1 to 14 A watch glass module film pasting and detection device, comprising:

[0049] The AOI detection module 2 comprises a turntable 4 rotatably arranged in the middle of the machine table 3, an AOI detection station 5 for detecting the PCBA surface of the product 1 is arranged beside the turntable 4, and a film tearing mechanism 6 for removing the packaging film of the product 1 is arranged on the side of the turntable 4 away from the AOI detection station 5;

[0050] An optical detection module 11 for optically detecting the glass surface of the product 1 is arranged beside the machine table 3;

[0051] The optical detection module 11 is provided with a film pasting module 12 on the side away from the machine table 3, the film pasting module 12 comprises a rotary table 14 rotatably arranged in the middle of a machine frame 13, a dust removal mechanism 16 is arranged beside a feeding manipulator 15 at the rotary table 14, a film pasting mechanism 19 is arranged beside the dust removal mechanism 16, the film pasting mechanism 19 takes the film from the feeder 26 and pastes it on the upper end of the product 1, and a rolling mechanism 27 for extruding the film is arranged beside the film pasting mechanism 19;

[0052] The film tearing mechanism 6 and the rolling mechanism 27 are provided with a turnover mechanism 37 on the side thereof for turning the product 1, and a discharging manipulator 44 is arranged on the side of the turnover mechanism 37.

[0053] The rack 13 is provided with a stacking station 45 for transferring the product 1.

[0054] During the operation of the device, the product 1 is moved by the feeding manipulator 15 at the machine table 3 to the rotating disc 4 in the middle of the machine table 3, and the PCBA of the product 1 is arranged upward and is driven to move by the rotating disc 4. During the movement, the AOI detection station 5 detects the PCBA surface of the product 1, and then the discharging manipulator 44 at the machine table 3 carries the product 1 to the turnover mechanism 37, and the turnover mechanism 37 turns over the product 1 (i.e., the PCBA surface of the product 1 is turned downward, and the glass surface of the product 1 is turned upward), and then the discharging manipulator 44 at the machine table 3 moves the turned product 1 to the film tearing mechanism 6 to remove the packaging film.

[0055] The product 1 after removing the packaging film is moved to the optical detection module 11 for optical detection to detect the defects of the glass surface.

[0056] The product 1 after the optical detection is moved by the feeding manipulator 15 at the rack 13 to the upper end of the rotating table 14 at the film pasting mechanism 19, and then the rotating table 14 rotates, and the glass surface of the product 1 is first removed from the dust removal mechanism 16, and then is pasted with the film piece at the film pasting mechanism 19. In order to improve the adhesion of the film piece and the glass surface of the product 1, when the product 1 moves to the side of the rolling mechanism 27, the rolling mechanism 27 will extrude the film piece on the glass surface of the product 1, and then the product 1 moves to the code scanning mechanism 35 for identification, and the identified product 1 moves to the turnover mechanism 37 on the side of the rotating table 14, at this time the turnover mechanism 37 drives the product 1 to turn over, and finally the product 1 is moved by the discharging manipulator 44 at the rack 13 to the stacking station 45 for batch transfer of OK products and NG products.

[0057] It should be noted that in the above process, although the feeding manipulator 15 and the discharging manipulator 44 are both prior art, because the processing objects and operation requirements are different, the feeding manipulator 15 and the discharging manipulator 44 on the side of the machine table 3 and the feeding manipulator 15 and the discharging manipulator 44 at the rack 13 have differences in appearance, which is the result of selecting the mechanical structure that adapts to the requirements of each process in the prior art, and finally showing the difference in appearance. This is the embodiment of the principle of “selecting according to needs” in the actual processing process. In different scenarios, mature and suitable structures are preferred, rather than uniform design.

[0058] In order to supplement the specific structure of the film tearing mechanism 6, the following features are further provided:

[0059] ReferenceFigure 3 、 Figure 4 and Figure 5 , the film tearing mechanism 6 further comprises a single-axis moving mechanism 7 arranged beside the rotating disc 4, the output end of the single-axis moving mechanism 7 is fixedly connected with a sliding cylinder 8, the output end of the sliding cylinder 8 is fixedly connected with a clamping jaw 9, and the two clamping ends of the clamping jaw 9 are used to clamp one side of the packaging film of the product 1. After the product 1 is transported to the corresponding position of the film tearing mechanism 6, the single-axis moving mechanism 7 can drive the sliding cylinder 8 to move accurately in the horizontal direction in the X-axis and Y-axis directions, so as to adjust the position of the clamping jaw 9, so that the two clamping ends of the clamping jaw 9 can accurately align the edge of the packaging film of the product 1. After the two clamping ends of the clamping jaw 9 clamp the packaging film, the sliding cylinder 8 drives the clamping jaw 9 to move in a diagonal direction (for reference Figure 5 ), and cooperates with the linkage of the single-axis moving mechanism 7 to smoothly tear the packaging film from the product 1.

[0060] In order to improve the friction between the clamping jaw 9 and the packaging film of the product 1, the following features are further provided:

[0061] As shown in Figure 6 , the side of the two output ends of the clamping jaw 9 close to each other is provided with an anti-static ceramic 10. When the two clamping ends of the clamping jaw 9 clamp the packaging film of the product 1, the anti-static ceramic 10 can increase the friction between the two clamping ends and the packaging film, avoid the packaging film from falling off due to insufficient clamping force during the film tearing process, ensure the stability and reliability of the film tearing action, and also prevent the clamping end of the clamping jaw 9 from damaging the packaging film, and ensure the edge of the packaging film of the product 1 after tearing is neat.

[0062] In order to supplement the specific structure of the dust removal mechanism 16, the following features are further provided:

[0063] As shown in Figure 9 and Figure 10 , the dust removal mechanism 16 comprises an ion air gun 18 obliquely arranged beside the rotating table 14, and a tubular air nozzle 17 is fixedly connected to the output end of the ion air gun 18. When the product 1 moves to the dust removal mechanism 16 with the rotating table 14, the ion air gun 18 is started, and high-pressure gas is sprayed obliquely to the glass surface of the product 1 through the tubular air nozzle 17. Due to the oblique arrangement of the tubular air nozzle 17, the sprayed gas can more comprehensively cover the glass surface of the product 1, blow off the impurities such as floating dust attached to the glass surface, so as to provide a clean surface environment for the subsequent film pasting process, and avoid the influence of impurities on the pasting effect of the film and the glass surface.

[0064] In order to supplement the specific structure of the film pasting mechanism 19, the following features are further provided:

[0065] As shown in Figure 9 , Figure 11 and Figure 13The film pasting mechanism 19 comprises a three-axis moving mechanism 20 arranged beside the rotary table 14, the output end of the three-axis moving mechanism 20 is fixedly connected with a fixing frame 21, and the lower end of the fixing frame 21 is elastically provided with a first vacuum chuck 22. When the film pasting operation is needed, the three-axis moving mechanism 20 drives the fixing frame 21 to move accurately in X, Y and Z directions, so that the first vacuum chuck 22 can be accurately moved to the feeder 26 to suck the film. After the film is sucked, the three-axis moving mechanism 20 is driven to accurately move the film to the upper side of the glass surface of the product 1, and then the first vacuum chuck 22 is controlled to descend, so that the film is preliminarily pasted on the glass surface of the product 1.

[0066] In order to supplement the elastic connection structure between the first vacuum chuck 22 and the fixing frame 21, the following features are further provided:

[0067] As shown in Figure 13 , the upper end of the first vacuum chuck 22 is fixedly connected with two first rolling bearings 23, the upper ends of the two first rolling bearings 23 are fixedly connected through a pin 25, and the first rolling bearing 23 is in sliding connection with the fixing frame 21.

[0068] The side close to the two first rolling bearings 23 is provided with a buffer spring 24, the lower end of the buffer spring 24 is fixedly connected with the first vacuum chuck 22, and the upper end is fixedly connected with the fixing frame 21.

[0069] When the first vacuum chuck 22 descends to contact the glass surface of the product 1 and pastes the film, the first rolling bearing 23 slides in the fixing frame 21, which guides the movement of the first vacuum chuck 22 and prevents it from deviating. At the same time, the buffer spring 24 is compressed to generate upward elastic force, thereby buffering the pressure of the first vacuum chuck 22 on the glass surface of the product 1, avoiding damage to the glass surface due to excessive pressure, and ensuring the safety of the film pasting process.

[0070] In order to supplement the specific structure of the rolling mechanism 27, the following features are further provided:

[0071] As shown in Figure 9 , Figure 11 and Figure 14 , the rolling mechanism 27 comprises a telescopic cylinder 28 arranged beside the rotary table 14, the telescopic cylinder 28 is arranged in a horizontal state and the output end is fixedly connected with a micro air cylinder 29.

[0072] The output end of the micro air cylinder 29 is downwardly arranged and fixedly connected with an adapter seat 30, and the lower end of the adapter seat 30 is elastically provided with a rolling shaft 34 for rolling the film on the upper end of the product 1.

[0073] When the product 1 is initially pasted with the film and moves to the rolling mechanism 27 with the turntable 14, the telescopic cylinder 28 is started to drive the micro cylinder 29, the adapter seat 30 and the rolling shaft 34 to move towards the product 1, and when the rolling shaft 34 reaches the preset position above the product 1, the micro cylinder 29 drives the adapter seat 30 and the rolling shaft 34 to move downwards, so that the rolling shaft 34 contacts with the film and rolls to remove the air bubbles between the film and the glass surface.

[0074] In order to supplement the elastic connection structure between the rolling shaft 34 and the adapter seat 30, the following features are further provided:

[0075] As shown in Figure 14 , the lower end of the adapter seat 30 is provided with the shaft seat 33, the upper end of the shaft seat 33 is fixedly connected with two second rolling bearings 31, the second rolling bearings 31 are in sliding connection with the adapter seat 30, the outside of the second rolling bearings 31 is sleeved with the adapter spring 32, and the two ends of the rolling shaft 34 are rotatably connected with the shaft seat 33.

[0076] The upper end of the adapter spring 32 is fixedly connected with the adapter seat 30, and the lower end is fixedly connected with the shaft seat 33.

[0077] During the rolling process of the rolling shaft 34 on the film, when the surface of the film is uneven or has a small protrusion, the shaft seat 33 will slide in the adapter seat 30 through the second rolling bearing 31, and the adapter spring 32 will expand and contract accordingly, providing a certain buffer and elastic pressure for the rolling shaft 34, so that the rolling shaft 34 can always closely adhere to the surface of the film, ensuring the uniformity of the rolling effect and further improving the adhesion of the film to the glass surface.

[0078] In order to supplement the specific structure of the code scanning mechanism 35 and further realize the identification of the information of the product 1, the following features are further provided:

[0079] As shown in Figure 8 and Figure 11 , the code scanning mechanism 35 includes a code scanning camera 36 arranged below the turntable 14, and the code scanning camera 36 is provided with a light source 361 on the side close to the turntable 14. After the product 1 is treated by the rolling mechanism 27, it moves to the code scanning mechanism 35 with the turntable 14, and the light source 361 is turned on to provide sufficient brightness for the code scanning camera 36, so as to ensure that the code scanning camera 36 can clearly capture the bar code or two-dimensional code on the product 1. The code scanning camera 36 identifies the bar code to obtain the related information of the product 1, so as to classify and trace the product 1 in the future.

[0080] In order to supplement the specific structure of the turnover mechanism 37, the following features are further provided:

[0081] The tilting mechanism 37 includes a lifting mechanism 38. The lifting mechanism 38 located next to the turntable 4 is fixedly connected to the machine base 3, and the lifting mechanism 38 located next to the turntable 14 is fixedly connected to the machine frame 13.

[0082] like Figure 12 As shown, a motor 39 is fixedly connected to the output end of the lifting mechanism 38. A transfer frame 42 is provided on the side of the motor 39. A main pulley 40 is fixedly connected to the output end of the motor 39 along the same axis. The main pulley 40 is rotatably connected to the transfer frame 42. An auxiliary pulley 41 is provided above the main pulley 40 and is rotatably connected to the transfer frame 42. The main pulley 40 and the auxiliary pulley 41 are connected by belt drive. A second vacuum suction cup 43 is provided on the side of the transfer frame 42 away from the motor 39.

[0083] When product 1 needs to be flipped, the lifting mechanism 38 drives the motor 39, the adapter frame 42, and the second vacuum suction cup 43 to rise or fall to a preset height, so that the second vacuum suction cup 43 contacts the surface of product 1 and adheres to product 1. Then the motor 39 starts, driving the main pulley 40 to rotate. The main pulley 40 drives the auxiliary pulley 41 to rotate through the belt, thereby causing the adapter frame 42 and the second vacuum suction cup 43, along with product 1, to flip, realizing the flipping operation of product 1. After the flipping is completed, the second vacuum suction cup 43 releases product 1, and the unloading mechanical claw carries product 1 away from the second vacuum suction cup 43 and places product 1 at the stacking station 45. Finally, the lifting mechanism 38 drives all components to reset, waiting for the next flipping operation.

[0084] The detailed working principle of this device is as follows: The operation of the entire device is coordinated by the control system, and each mechanism cooperates in an orderly manner according to the preset program. First, product 1 is accurately picked up by the loading robot 15 at machine station 3 and transferred to the turntable 4 in the middle of machine station 3. At this time, the PCBA side of product 1 is facing upwards. The turntable 4 starts to rotate under the drive of the drive device, transporting product 1 to each workstation. When product 1 moves to AOI inspection station 5, AOI inspection station 5 starts and performs a comprehensive inspection of the PCBA side of product 1, including whether the circuit is intact and whether the solder joints are qualified. The inspection data is transmitted to the control system in real time for analysis and judgment.

[0085] After inspection, the unloading robot 44 at machine 3 removes product 1 from turntable 4 and transports it to the flipping mechanism 37. The lifting mechanism 38 of the flipping mechanism 37 first adjusts the height so that the second vacuum suction cup 43 contacts and firmly adheres to product 1. Then, the motor 39 drives the main pulley 40 to rotate, which in turn drives the auxiliary pulley 41 to rotate via belt transmission, thereby flipping the adapter frame 42 and the second vacuum suction cup 43, turning product 1 so that the PCBA side faces down and the glass side faces up. After flipping, the unloading robot 44 at machine 3 transfers the flipped product 1 to the film-peeling mechanism 6.

[0086] The single-axis moving mechanism 7 of the film tearing mechanism 6 drives the sliding cylinder 8 and the clamping jaw 9 to move, so that the clamping jaw 9 is aligned with the edge of the packaging film of the product 1, and the output end of the clamping jaw 9 clamps the packaging film with the assistance of the anti-static ceramic 10. Then, the sliding cylinder 8 and the single-axis moving mechanism 7 act in coordination to smoothly tear the packaging film, and the torn packaging film is collected and processed.

[0087] The product 1 with the removed packaging film is transferred to the optical detection module 11. The optical detection device detects the glass surface of the product 1 by using high-precision optical imaging technology, accurately identifies defects such as scratches, bubbles, impurities, etc. on the glass surface, and feeds back the detection results to the control system.

[0088] The product 1 that has undergone optical detection is transferred to the upper end of the turntable 14 by the loading manipulator 15 at the turntable 14. The turntable 14 starts to rotate, first conveying the product 1 to the dust removal mechanism 16. The ion air gun 18 sprays high-pressure gas obliquely to the glass surface through the tubular air nozzle 17, completely removing the surface dust and dirt. Then, the product 1 is transferred to the film pasting mechanism 19. The three-axis moving mechanism 20 drives the fixed frame 21 and the first vacuum chuck 22 to move to the film feeder 26. After the first vacuum chuck 22 sucks the film piece, the film piece is accurately and gently pasted on the glass surface under the action of the first rolling bearing 23 and the buffer spring 24.

[0089] Subsequently, the product 1 moves to the rolling mechanism 27. The telescopic cylinder 28 pushes the micro-cylinder 29, the adapter seat 30, and the rolling shaft 34 to approach the product 1. The micro-cylinder 29 drives the rolling shaft 34 to descend. Under the buffering action of the second rolling bearing 31 and the adapter spring 32, the rolling shaft 34 uniformly rolls the film piece, removes the bubbles between the film piece and the glass surface, and enhances the adhesion. After rolling is completed, the product 1 is transferred to the code scanning mechanism 35. The light source 361 provides sufficient light, and the code scanning camera 36 scans and identifies the bar code or two-dimensional code on the product 1, obtains the product 1 information, and transmits it to the control system.

[0090] After identification is completed, the product 1 moves to the turnover mechanism 37 beside the turntable 14. The turnover mechanism 37 turns over the product 1 according to the same principle as before, so that the product 1 returns to a suitable state. Finally, the unloading manipulator 44 beside the turntable 14 takes the product 1 from the turntable 14 and transfers it to the stacking station 45. The stacking station 45 transfers the OK products and the NG products to corresponding trays according to the detection results fed back by the control system, and completes the film pasting and detection process of the entire watch glass module.

[0091] The above embodiments only express one or several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
