Description

Technical Field

[0001] The present invention relates to the technical field of film pasting equipment, and in particular to an adaptive film pasting equipment based on visual detection. Background Art

[0002] Machine vision technology is a technology that uses computers to simulate human visual functions, extract information from images of objective objects, process and understand it, and ultimately use it for actual detection, measurement and control. In recent years, with the continuous advancement of technologies such as artificial intelligence and deep learning, machine vision technology has developed rapidly, and its application in industrial automation, intelligent manufacturing and other fields has become increasingly extensive. In industrial production, film laminating equipment is widely used in the production process of electronic products such as mobile phones, tablets, and touch screens. Traditional film laminating equipment mainly relies on manual operation or simple mechanical positioning, and has problems such as low film laminating accuracy, low efficiency, and high labor costs. With the improvement of product accuracy and the increase in demand for production efficiency, traditional film laminating equipment has been difficult to meet production requirements.

[0003] The prior art also has the following defects during use:

[0004] In the process of film pasting in the prior art, because the main lighting mechanism and detection mechanism of the film pasting table are generally concentrated in the center of the equipment, and the product placement table is generally not fixed at the center of the equipment, it needs to be placed manually at the center of the equipment. During the manual placement process, it is easy to cause a certain degree of deviation, which leads to the inability to carry out the detection and film pasting work well. Therefore, under the premise of ensuring stable transportation, the products placed on the placement table need to be fixed, so that the products can be stably placed at the processing point of the film pasting equipment during the transportation process; the general detection mechanism can be fixed at the processing point of the film pasting equipment, but the overall operation of the fixed detection mechanism is relatively rigid, and it is not convenient for subsequent adjustment, and it will occupy more working space in the center of the processing equipment, which is not conducive to maintenance and other treatments of the equipment; the film pasting detection probes of the film pasting mechanism are usually fixed on both sides. This design will affect the film pasting work to a certain extent, and it is easy to cause inconvenience to the film pasting work.

[0005] In view of this, we propose an adaptive film-sticking device based on visual detection to solve the existing problems. Summary of the invention

The third rack is meshed and installed with the upper layer of the large gear. The clamping movable part is connected with a fourth rack. The fourth rack is meshed and installed with the lower layer of the large gear.

[0009] The rotation of the main gear drives the sub-gear to rotate synchronously. The rotation of the sub-gear drives the film placement table to fix and clamp the product, and then drives the film placement table with the product fixed to slide. At the same time, the rotation of the main gear drives the film placement mechanism to slide so that the film placement mechanism is centered with the fixed product.

[0010] Preferably, the film-sticking mechanism comprises a moving part, a driving part, a first sliding block and a second sliding block, a mounting plate is arranged at the lower end of the film-sticking mechanism, a plurality of groups of grooves are symmetrically arranged on the surface of the mounting plate, and the moving part, the first sliding block and the second sliding block are slidably mounted on the grooves.

[0013] The driving member controls the movement of the moving member, and the movement of the moving member drives the first sliding block and the second sliding block to slide through the connecting rod so that the visual inspection light is close to or away from the product processing position.

[0014] Preferably, a film sticking table is arranged on the film sticking placement table, a groove is arranged on one side of the film sticking table, and the clamping movable part is slidably installed on one side of the film sticking table through the groove.

[0015] Preferably, the initial position state of the film sticking mechanism installed on the upper slide rail is relatively forward relative to the initial position state of the film sticking placement table installed on the lower slide rail.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention provides a mechanism in the film pasting device that can simultaneously realize the movement of the film pasting mechanism and the movement and clamping function of the placement table, and places the film pasting placement table at the middle of the lower end of the film pasting mechanism. Through the action transmission of the gear and the rack, when the film pasting mechanism moves to the center, the film pasting placement table first realizes clamping through the movement of the rack. After the clamping is completed, the film pasting mechanism and the film pasting placement table are in the same vertical direction together, and move to the arc lamp at the center while maintaining the alignment state. The overall mechanism can better adjust itself to the state most suitable for work; under the action of the driving part, the moving part of the film pasting mechanism starts to move downward. In the process of the moving part moving downward, due to the linkage relationship between the connecting rod and the first sliding block and the second sliding block, the visual inspection light is close to the contact surface between the film pasting wheel and the film pasting product. After the detection is completed, the moving part is reset to drive the visual inspection light to reset together. While ensuring visual inspection, it can also avoid the influence of the visual inspection lights on the film pasting product on both sides. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiment 1

[0030] like Figure 1-Figure 5 As shown, an adaptive film pasting device based on visual inspection proposed by the present invention includes a film pasting device 1, a workbench front plate 2 and a workbench rear plate 16 are arranged at the lower end of the film pasting device 1, an upper slide rail 5 and a lower slide rail 7 are respectively arranged at the upper end and the lower end of the workbench front plate 2, a main gear 15 and a sub-gear 18 are installed on the workbench rear plate 16, and the main gear 15 and the sub-gear 18 are meshingly installed, the main gear 15 is meshingly connected with a first rack 13, the first rack 13 is slidably installed on the upper slide rail 5, and the first rack 13 is fixedly connected with a film pasting mechanism 28, the sub-gear 18 is meshingly connected with a second rack 17, the second rack 17 is installed on the lower slide rail 7, and the second rack 17 is fixedly connected with a film pasting placement table 6.

[0031] The front working plate and the rear working plate are integrally arranged to form the lower working table of the film pasting equipment 1. The rear working plate is the working mounting plate 30 for mainly mounting gears and other mechanisms. The main gear 15 is driven by an external driving mechanism, thereby driving the sub-gear 18 to rotate together. During the rotation of the main gear 15 and the sub-gear 18, the first rack 13 and the second rack 17 can be driven to move. During the movement of the first rack 13, the film pasting mechanism 28 can be driven to move toward the center, and during the movement of the second rack 17, the film pasting placement table 6 can also be driven to move and clamp.

[0032] The film placement table 6 includes a connecting block 23, a clamping movable part 21, and a large gear 25. The large gear 25 is fixedly installed. The film placement table 6 is connected and fixed by the connecting block 23 and the second rack 17. The connecting block 23 penetrates the film placement table 6 and is internally connected to a third rack 24. The third rack 24 is meshed with the upper layer of the large gear 25. The clamping movable part 21 is connected to a fourth rack 26. The fourth rack 26 is meshed with the lower layer of the large gear 25.

[0033] The film placement table 6 is connected by a connecting block 23 and the second rack 17. When the connecting block 23 begins to be subjected to the pulling force brought by the movement of the second rack 17, because the friction between the connecting block 23 and the side wall of the film placement table 6 is small, the connecting block 23 moves in the slide groove 22 of the film placement table 6. During the movement of the connecting block 23, the internal third rack 24 is driven to move, and the third rack 24 transmits the movement to the upper end of the large gear 25. Because of the fixed relationship between the upper end of the large gear 25 and the lower end of the large gear 25, the lower end of the large gear 25 moves with the upper end of the large gear 25, and because of the movement of the lower end of the large gear 25, the fourth rack 26 starts to move, thereby driving the clamping movable member 21 to perform a sliding clamping action on the side of the film placement table 19.

[0034] The rotation of the main gear 15 drives the sub-gear 18 to rotate synchronously. The rotation of the sub-gear 18 drives the film placement table 6 to fix and clamp the product, and then drives the film placement table 6 with the product fixed to slide. At the same time, the rotation of the main gear 15 drives the film placement mechanism 28 to slide so that the film placement mechanism 28 is centered with the fixed product.

[0035] Furthermore, the film-sticking mechanism 28 includes a moving part 31, a driving part 41, a first sliding block 37 and a second sliding block 35. A mounting plate 30 is provided at the lower end of the film-sticking mechanism 28. A plurality of groups of grooves 27 are symmetrically provided on the surface of the mounting plate 30. The moving part 31, the first sliding block 37 and the second sliding block 35 are slidably installed on the grooves 27.

[0036] A mounting plate 30 is provided at the film-sticking mechanism 28 , and the mounting plate 30 can move to a certain extent at the film-sticking mechanism 28 , and a plurality of groups of slots 27 are provided on the surface of the mounting plate 30 , which can well support the installation of the moving part 31 , the first sliding block 37 and the second sliding block 35 .

[0037] Furthermore, the movable member 31, the first sliding block 37 and the second sliding block 35 are all provided with a hinge ring 29, and a connecting rod 36 is connected between the movable member 31, the first sliding block 37 and the second sliding block 35 via the hinge ring 29. The driving member 41 is installed on the upper end of the movable member 31, and a film sticking wheel 33 is provided at the lower end of the movable member 31. The second sliding block 35 is provided with a visual detection light 34 near the film sticking position.

[0038] The moving member 31, the first sliding block 37 and the second sliding block 35 are all connected by a hinge ring 29 and a connecting rod 36. In this connection structure, due to the movement of the moving member 31, the first sliding block 37 will follow the moving member 31 to move in the slot 27, and the second sliding block 35 will also follow the first sliding block 37 to move in the slot 27. Due to the different setting angles, when the moving member 31 moves downward, the second sliding block 35 will approach the lower end of the moving member 31, and the film sticking wheel 33 and the visual detection light 34 are respectively installed at the lower end of the moving member 31 and the lower end of the second sliding block 35. Therefore, the visual detection light 34 will approach the film sticking wheel 33 when the film sticking wheel 33 is working, and stay away from the film sticking wheel 33 when the film sticking wheel 33 is not working, according to the position of the film sticking wheel 33.

[0039] Furthermore, a control member 38 is provided on one side of the upper end of the film sticking mechanism 28, and the control member 38 is connected to a spiral rod 39, and a mounting block is installed on the spiral rod 39, and the mounting block is fixedly connected to the driving member 41;

[0040] The driving member 41 controls the movement of the moving member 31 , and the movement of the moving member 31 drives the first sliding block and the second sliding block 35 to slide through the connecting rod 32 so that the visual inspection light 34 is close to or away from the product processing location.

[0041] The control member 38 controls the installation block to move left and right to a certain extent through the screw rod 39, and the installation block and the driving member 41 are fixed. During the movement of the installation block, the driving member 41 and the lower end of the installation plate 30 will move left and right, so that the film sticking wheel 33 can effectively stick the film.

[0042] Furthermore, a film sticking table 19 is provided on the film sticking placement table 6 , a groove is provided on one side of the film sticking table 19 , and the clamping movable member 21 is slidably installed on one side of the film sticking table 19 through the groove.

[0043] The clamping movable member 21 is installed on one side of the film pasting table 19. The film pasting table 19 is the main space for placing the film pasting products. The clamping movable member 21 can slide through the groove to clamp the film pasting products.

[0044] Furthermore, the initial position state of the film pasting mechanism 28 installed on the upper slide rail 5 is relatively forward relative to the initial position state of the film pasting placement table 6 installed on the lower slide rail 7 .

[0045] The film sticking mechanism 28 is positioned forward of the film sticking table 6 because the main gear 15 and the sub-gear 18 of the same size, and the first rack 13 and the second rack 17 have the same movement speed, and most product specifications are basically the same. The film sticking table 6 needs to be fixed before it can move. Therefore, in order to keep the film sticking mechanism 28 and the film sticking table 6 in a centered state, the film sticking mechanism 28 needs to be set forward relative to the film sticking table 6.

[0046] Furthermore, a slide groove 22 is provided on one side of the film placement platform 6, and the connecting block 23 is slidably installed in the slide groove 22. A mounting base 20 is provided at the lower end of the film placement platform 6, and the film placement platform 6 is installed on the lower slide rail 7 through the mounting base 20.

[0047] The connecting block 23 connects the second rack 17 and the third rack 24 via the slide groove 22 , and the friction force applied to the connecting block 23 in the slide groove 22 is generally smaller than the friction force between the mounting base 20 and the lower slide rail 7 .

[0048] Furthermore, a film sticking sliding block 4 is connected to the upper end of the film sticking mechanism 28 , and the film sticking sliding block 4 is slidably mounted on the upper slide rail 5 . The film sticking mechanism 28 is fixedly connected to the first rack 13 via the film sticking sliding block 4 .

[0049] The film sticking sliding block 4 at the upper end of the film sticking mechanism 28 can form an integral mounting block with the first rack 13 , so that it can be slidably mounted on the upper slide rail 5 to support the movement of the film sticking mechanism 28 .

[0050] Furthermore, a control console 3 is provided at one side of the lower end of the film sticking device 1 , a display screen 8 is installed at the upper end of the film sticking device 1 , and the control console 3 and the display screen 8 are electrically connected.

[0051] The console 3 can control the display of the display screen 8 , and the console 3 can also control the actions of multiple groups of equipment. The display screen 8 is used to display the images detected by the visual detection light 34 .

[0052] Furthermore, the film-sticking equipment 1 is provided with a plurality of groups of external extension blocks 9 between the display screen 8 and the workbench front panel 2, the external extension blocks 9 are provided with hinge seats 10, a mechanical arm 12 is provided at the lower end of the hinge seat 10, and the mechanical arm 12 is connected to an arc lamp 11.

[0053] The film laminating equipment 1 is provided with an outward extension block 9 for installing an adjustable mechanical arm 12, and an arc lamp 11 is provided at one end of the mechanical arm 12 for illuminating the film laminating product at the working point and enhancing the image collection of the film laminating process by the visual inspection lamp 34, thereby ensuring the smooth progress of the film laminating work.
