Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to an automatic bonding device for automotive screens. Background Technology

[0002] As living standards improve, people have higher and higher requirements for car interiors, and car screens have evolved from button-type to touch-screen. To make cars more aesthetically pleasing, the central control screen and instrument panel are installed in a single back cover to form a dual-screen setup. However, existing dual-screen setups are usually laid flat, so when viewing a dual-screen setup, one can only face one screen directly, making it difficult for the driver to see both screens simultaneously, which is inconvenient for the driver to use.

[0003] In the existing technology, V-shaped dual screens have appeared on the market. The screen and the bottom frame are V-shaped. Most steps are assembled manually. The screen and the bottom frame are not easy to align, which can easily lead to deviations. Moreover, manual assembly is relatively slow, and the accuracy of manual alignment is low, which can easily produce defective products. Rework is also quite troublesome, resulting in high production and labor costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides an automatic bonding device for automotive screens, which assembles the screen onto the base frame through mechanical automation. It operates stably, has a high assembly qualification rate, thereby reducing labor costs and increasing production speed.

[0005] This invention discloses an automatic bonding device for automotive screens, characterized in that it includes a frame, on which a feeding station, a pre-pressing station, a testing station and a pressure holding station are sequentially arranged along the Y-axis.

[0006] Along the Z-axis direction, the loading station is provided with a screen mounting base for assembling the screen and a bottom frame mounting base for assembling the bottom frame. The screen mounting base is provided with an adsorption component for adsorbing or releasing the screen. The bottom frame mounting base is provided with several pressure sensors for detecting the pressure at the corresponding position of the bottom frame, and also includes a height sensor for detecting the height of the bottom frame position on the bottom frame mounting base, so as to prevent the product from being crushed due to not being placed flat.

[0007] The frame is also provided with a screen lifting drive assembly for driving the screen mounting base to rise and fall along the Z-axis, a screen rotation drive for driving the screen mounting base to rotate circumferentially around the X-axis, and a screen sliding drive assembly for driving the screen mounting base to slide along the Y-axis at the position corresponding to the screen mounting base. The loading station is provided with a first visual sensor above the screen mounting base for taking pictures of the screen on the screen mounting base.

[0008] The pressing component is located above the bottom frame mounting base, which is slidably mounted on the frame along the Y-axis. The frame is also equipped with a bottom frame drive assembly for driving the bottom frame mounting base to reciprocate between the loading station, the pre-pressing station, the inspection station, and the pressure holding station.

[0009] The frame is equipped with a second vision sensor for capturing images of the screen and screen mounting base at the pre-pressing station position;

[0010] The frame is equipped with a third vision sensor at the detection station for photographing the bottom frame on the bottom frame mounting base;

[0011] The frame is equipped with a pressure-holding component at the pressure-holding station position for pressing the screen against the bottom frame and a pressure-holding drive assembly for driving the pressure-holding component to slide along the Z-axis direction.

[0012] Using the above technical solution, the processed screen is assembled onto the screen mounting base, and then the suction component holds the screen in place to prevent slippage. Next, the protective film on the screen is removed. Then, a first vision sensor takes a picture of the screen on the mounting base. The photograph determines whether the protective film has been completely removed and whether the screen is correctly positioned. The screen mounting base is then slid to the pre-pressing station by a screen sliding drive assembly. A second vision sensor then takes a picture of the position of the screen and the mounting base to further determine the screen's position. Finally, the cleaned bottom frame is assembled onto the bottom frame mounting base. A height sensor detects the height of the bottom frame on the mounting base, and the bottom frame drive assembly drives the mounting base to slide along the Y-axis. When the bottom frame mounting base slides to the detection station, a third vision sensor takes a picture of the bottom frame mounting base and the bottom frame to further determine the bottom frame's position. The screen mounting base is then slid to the pre-pressing station and positioned below the screen mounting base by the bottom frame drive assembly. At this time, the screen rotation drive component drives the screen mounting base to rotate, aligning the screen with the bottom frame. Then, the screen lifting drive component lowers the screen mounting base, placing the screen on the bottom frame. Further, the suction component releases the screen, and the screen lifting drive component, screen rotation drive component, and screen sliding drive component work together to return the screen mounting base to the loading station position. The bottom frame drive component then slides the bottom frame with the screen to the pressure holding station. Further, the pressure holding drive component drives the pressure-holding component to press the screen, further assembling the screen onto the bottom frame. During the pressing process, pressure sensors detect the pressure at multiple locations on the bottom frame and provide feedback, allowing for monitoring of the pressing force to prevent uneven pressure on the bottom frame. After a certain pressing time, the pressure holding drive component resets the pressure-holding component, achieving automatic screen assembly.

[0013] A further feature of the present invention is that the screen mounting base is provided with an assembly bracket for assembling the screen. The assembly bracket includes a left mounting plate and a right mounting plate that are separately configured and hinged together. Both the left and right mounting plates are inclined to form an inverted V-shaped mounting surface adapted to the screen. The screen mounting base is also provided with a first adjustment structure for adjusting the inclination angle of the left and right mounting plates. When the screen mounting base is located at the loading station and the screen is not assembled, the inverted V-shaped mounting surface is flipped to tilt outward.

[0014] By adopting the above technical solution, the mounting bracket can facilitate the installation of the screen. Moreover, by adjusting the tilt angle of the left and right mounting plates through the first adjustment structure, the opening angle of the mounting bracket can be changed, and the opening degree of the inverted V-shaped mounting surface can be further adjusted, thus making it suitable for assembling screens with different opening degrees, which enhances its practicality. Furthermore, the inverted V-shaped mounting surface can be flipped to tilt outward, which makes the assembly process more convenient. In addition, the inverted V-shaped mounting surface can be adapted to the screen to make it fit more closely during assembly.

[0015] A further embodiment of the present invention includes: a pressure-holding drive assembly comprising a guide rod arranged along the Z-axis, a lower pressure seat slidably arranged on the guide rod, and a lower pressure drive member for driving the lower pressure seat downward; a pressure abutment member is arranged on the lower pressure seat and slides synchronously therewith; the pressure abutment member comprises a left pressure plate and a right pressure plate that are separately arranged and hinged together; the left pressure plate and the right pressure plate are inclined, and their lower end faces are fitted to form a V-shaped pressure surface adapted to the screen; the lower pressure seat is also provided with a second adjustment structure for adjusting the tilt angle of the left pressure plate and the right pressure plate.

[0016] Using the above technical solution, the guide rod can guide the sliding of the lower pressure seat, preventing it from deviating and making it more stable during sliding, further improving accuracy. The left and right pressure plates are hinged together, so their tilt angle can be changed through the second adjustment structure, thereby adjusting the opening degree of the V-shaped lower pressure surface. This is suitable for screens with different opening degrees, making it more practical. Furthermore, using the V-shaped lower pressure surface for pressing makes it more stable and the pressure more uniform during pressing.

[0017] A further feature of the present invention is that both the left and right mounting plates are provided with adsorption components, which extend through the corresponding mounting plates to the inverted V-shaped mounting surface. The screen mounting base is also provided with a telescopic drive component for driving the adsorption components to extend and retract relative to the inverted V-shaped mounting surface.

[0018] Using the above technical solution, both the left and right mounting plates are equipped with adsorption components to make them more stable during adsorption. After the screen is processed and formed, there will be a certain space for thermal expansion and contraction, which can easily deform it. By using the telescopic drive component to drive the adsorption component to extend and retract, the screen can be stretched and shaped to prevent deformation.

[0019] A further feature of the present invention is as follows: the first adjustment structure includes a mounting plate adjustment block that is slidably supported at the bottom of the left mounting plate and the bottom of the right mounting plate, and a first adjustment screw that drives the mounting plate adjustment block to slide along the X-axis. A first guide seat is provided on the screen mounting base at the position corresponding to the mounting plate adjustment block for guiding the sliding of the mounting plate adjustment block. The first adjustment screw is rotatably mounted on the first guide seat and threadedly engaged with the mounting plate adjustment block.

[0020] Using the above technical solution, when the mounting plate adjusting block slides on the first guide seat, it can prevent it from rotating. At this time, the mounting plate adjusting block can be driven to slide by rotating the first adjusting screw. The structure is simple, the installation is convenient, and the adjustment degree can be easily controlled by adjusting the screw, which meets the accuracy requirements.

[0021] A further feature of the present invention is that the bottom of both the left and right mounting plates is provided with telescopic drive components, and each telescopic drive component output end is connected to an adsorption component assembly plate for assembling adsorption components. Each adsorption component assembly plate is provided with several adsorption components that slide synchronously with it, and each adsorption component is a suction nozzle, which includes a flexible suction cup and an air suction hole located in the middle of the suction cup.

[0022] By adopting the above technical solution, the contact between the flexible suction cup and the screen can prevent hard collisions, thus better protecting the screen. Then, an air pump or other air suction device is connected to the air suction hole. The air suction hole is located in the middle of the suction cup, which can make it more effective during use.

[0023] A further feature of the present invention is that the second adjustment structure includes a pressure adjustment block that slides against the top of the left pressure plate and the right pressure plate, and a second adjustment screw that drives the pressure adjustment block to slide along the X-axis. The lower pressure seat is provided with a second guide seat for guiding the sliding movement of the pressure adjustment block. The second adjustment screw is rotatably mounted on the second guide seat and threadedly engaged with the pressure adjustment block.

[0024] By adopting the above technical solution, when the pressure adjustment block slides on the second guide seat, it can be prevented from rotating. At this time, the pressure adjustment block can be driven to slide by rotating the second adjusting screw. The structure is simple, the installation is convenient, and the adjustment degree can be easily controlled by adjusting the screw, which meets the accuracy requirements.

[0025] A further provision of the present invention includes: screen lifting drive assemblies on both sides of the screen mounting base; each set of screen lifting drive assemblies includes a screen lifting rail arranged along the Z-axis, a screen lifting frame slidably arranged on the screen lifting rail, and a screen lifting drive component for driving the screen lifting frame to slide; each screen lifting frame is rotatably provided with a support shaft; two support shafts are concentrically arranged and locked with the screen mounting base to form a support structure; a screen rotation drive component is provided on the screen lifting frame and is linked and cooperated with the support shaft; two sets of screen sliding drive assemblies are arranged opposite each other; each set of screen sliding drive assemblies includes a screen smooth rail arranged along the Y-axis, a slide block slidably arranged on the screen smooth rail, and a slide block drive component for driving the slide block to slide; the screen lifting rail and the slide block correspond one-to-one and slide synchronously with each other.

[0026] By adopting the above technical solution, the screen mounting base can be made more stable during lifting by two sets of screen lifting drive components. When the screen lifting drive component drives the screen lifting frame to lift and lower on the screen lifting rail, it can also drive the screen mounting base to lift and lower together. The screen lifting rail can also guide the screen lifting frame during lifting and lowering, further improving stability. When the slide drive component drives the slide to slide along the Y-axis, it can also drive the screen lifting rail to slide, thereby allowing the screen mounting base to slide along the Y-axis. The screen smooth rail can also guide the slide to slide along the Y-axis, preventing the slide from deviating. The support shaft on the screen lifting frame can support its opposite ends, increasing the structural strength of the support. The screen rotation drive component is located on the screen lifting frame and can lift and lower together with the screen lifting frame, making the layout more reasonable. Furthermore, the screen rotation drive component can drive the support shaft to rotate, which in turn drives the screen mounting base to rotate, making the linkage more convenient.

[0027] A further embodiment of the present invention: the bottom frame drive assembly includes a bottom frame smooth rail arranged along the Y-axis and a bottom frame drive component that drives the bottom frame mounting base to slide on the bottom frame smooth rail, wherein the bottom frame mounting base is directly or indirectly slidably arranged on the bottom frame smooth rail.

[0028] Using the above technical solution, the bottom frame drive component can drive the bottom frame mounting base to slide on the bottom frame smooth rail. At this time, the bottom frame smooth rail can act as a guide to prevent the bottom frame mounting base from shifting.

[0029] A further feature of the present invention is that two height sensors are arranged obliquely opposite each other and located at the bottom of the screen mounting base.

[0030] Using the above technical solution, when the bottom frame drive component moves the bottom frame mounting base along the Y-axis to the inspection station, it will pass through the pre-pressing station. At this time, the height sensor can detect the height of the bottom frame on the bottom frame mounting base, thereby determining whether the bottom frame assembly is qualified, reducing the generation of defective products. In addition, the height sensor is set at an angle relative to each other, which can achieve better results and higher accuracy when shooting. Attached Figure Description

[0049] This invention discloses an automatic bonding device for automotive screens. In an embodiment, the device includes a frame 1. Along the Y-axis, the frame 1 is sequentially equipped with a loading station 11, a pre-pressing station 12, a testing station 13, and a pressure holding station 14. Along the Z-axis, the loading station 11 is sequentially equipped with a screen mounting base 2 for assembling the screen and a bottom frame mounting base 3 for assembling the bottom frame. The screen mounting base 2 has an adsorption component 21 for adsorbing or releasing the screen. The bottom frame mounting base 3 has several pressure sensors 31 for detecting pressure at corresponding positions of the bottom frame (preferably four sensors, each corresponding to a corner of the bottom frame). It also includes a height sensor 50 for detecting the height of the bottom frame on the bottom frame mounting base 3 (this sensor detects whether the height of the bottom frame on the bottom frame mounting base 3 is higher than a set value, thus determining whether the bottom frame is properly assembled and preventing damage due to uneven placement). The frame 1 also has a screen lifting mechanism corresponding to the position of the screen mounting base 2 for driving the screen mounting base 2 to move up and down along the Z-axis. The system includes a lowering drive assembly 4, a screen rotation drive 5 that drives the screen mounting base 2 to rotate circumferentially around the X-axis, and a screen sliding drive assembly 6 that drives the screen mounting base 2 to slide along the Y-axis. A first visual sensor 30 for capturing images of the screen on the screen mounting base 2 is located above the screen mounting base 2 at the loading station 11. A pressing member is located above the bottom frame mounting base 3, which is slidably mounted on the frame 1 along the Y-axis. The frame 1 is also equipped with components for driving the bottom frame mounting base 3 at the loading station 11 and the pre-pressing station 1. 2. A bottom frame drive assembly 7 that reciprocates between the detection station 13 and the pressure holding station 14; a second vision sensor 40 for photographing the screen and screen mounting base 2 is provided on the frame 1 at the pre-pressure station 12; a third vision sensor 60 for photographing the bottom frame on the bottom frame mounting base 3 is provided on the frame 1 at the detection station 13; and a pressure holding drive assembly 9 for pressing the screen onto the bottom frame and driving the pressure holding member 8 to slide along the Z-axis is provided on the frame 1 at the pressure holding station 14.

[0050] Using the above technical solution, the processed screen is assembled onto the screen mounting base 2. Then, the suction component 21 holds the screen in place, preventing it from slipping. Next, the protective film on the screen is removed. Then, the first visual sensor 30 takes a picture of the screen on the screen mounting base 2. The photograph shows whether the protective film has been completely removed and whether the screen is in the correct position. Then, the screen sliding drive component 6 moves the screen mounting base 2 to the pre-pressing station 12. Finally, the second visual sensor 40 takes a picture of the position of the screen and the screen mounting base 2. First, the screen position is determined. Then, the cleaned bottom frame is assembled onto the bottom frame mounting base 3. The height sensor 50 detects the height of the bottom frame on the bottom frame mounting base 3. When an abnormal bottom frame height is detected, the bottom frame drive assembly 7 drives the bottom frame mounting base 3 back to the loading station 11 to reassemble the bottom frame. When the bottom frame height is detected to be normal, the bottom frame drive assembly 7 drives the bottom frame mounting base 3 to slide to the detection station 13. The third vision sensor 60 takes pictures of the bottom frame mounting base 3 and the bottom frame to further determine the position of the bottom frame. Then, the bottom frame drive assembly 7 moves the bottom frame mounting base... 3. The screen slides to the pre-pressing station 12 and is positioned below the screen mounting base 2. At this time, the screen rotation drive 5 drives the screen mounting base 2 to rotate, aligning the screen with the bottom frame. Then, the screen lifting drive assembly 4 lowers the screen mounting base 2, placing the screen on the bottom frame. Further, the suction component 21 releases the screen. The screen lifting drive assembly 4, screen rotation drive 5, and screen sliding drive assembly 6 work together to return the screen mounting base 2 to the loading station 11. The bottom frame drive assembly 7 drives the bottom frame containing the screen to slide to the pressure holding station 14. Further, the pressure holding drive assembly... Part 9 drives the pressing part 8 to press the screen, so that the screen is further assembled onto the bottom frame. During the pressing, the pressure sensor detects the pressure at multiple positions on the bottom frame and provides feedback, which can monitor the pressing force and prevent the bottom frame pressure from being unbalanced. After pressing for a certain period of time, the pressure holding drive component 9 drives the pressing part 8 to reset, realizing the automatic assembly of the screen. After assembly, a V-shaped screen is formed. It can return to the loading station 11 with the bottom frame mounting base 3 for unloading. Alternatively, an unloading station can be set up for unloading, or it can be directly unloaded at the pressure holding station 14.

[0051] The screen mounting base 2 is provided with an assembly bracket 22 for assembling the screen. The assembly bracket 22 includes a left mounting plate 221 and a right mounting plate 222 that are separately set and hinged together (preferably, the screen mounting base 2 is provided with a hinge seat, and the left mounting plate 221 and the right mounting plate 222 are hinged on the hinge seat). The left mounting plate 221 and the right mounting plate 222 are both inclined to form an inverted V-shaped mounting surface adapted to the screen. The screen mounting base 2 is also provided with a first adjustment structure 10 for adjusting the tilt angle of the left mounting plate 221 and the right mounting plate 222. When the screen mounting base 2 is located at the loading station 11 and the screen is not assembled, the inverted V-shaped mounting surface is flipped to tilt outward. Preferably, the screen mounting base 2 is rotated by the screen rotation drive 5, so that the inverted V-shaped mounting surface is tilted outward.

[0052] By adopting the above technical solution, the mounting bracket 22 can facilitate the installation of the screen. Moreover, by adjusting the tilt angle of the left mounting plate 221 and the right mounting plate 222 through the first adjustment structure 10, the opening angle of the mounting bracket 22 can be changed, and the opening degree of the inverted V-shaped mounting surface can be further adjusted, so as to be suitable for the assembly of screens with different opening degrees, which is more practical. Furthermore, the inverted V-shaped mounting surface can be flipped to tilt outward, which makes the assembly more convenient. In addition, the inverted V-shaped mounting surface can be adapted to the screen to make it fit better during assembly.

[0053] The pressure holding drive assembly 9 includes a guide rod 91 arranged along the Z-axis, a lower pressure seat 92 slidably arranged on the guide rod 91, and a lower pressure drive member 93 for driving the lower pressure seat 92 to press down. The pressure member 8 is arranged on the lower pressure seat 92 and slides synchronously with it. The pressure member 8 includes a left pressure plate 81 and a right pressure plate 82 that are separately arranged and hinged together (preferably, a hinge seat is arranged on the lower pressure seat 92, and then the left pressure plate 81 and the right pressure plate 82 are both hinged on the hinge seat). The left pressure plate 81 and the right pressure plate 82 are inclined, and their lower end faces are fitted to form a V-shaped lower pressure surface adapted to the screen. The lower pressure seat 92 is also provided with a second adjustment structure 20 for adjusting the tilt angle of the left pressure plate 81 and the right pressure plate 82.

[0054] Using the above technical solution, the guide rod 91 can guide the sliding of the lower pressure seat 92, preventing it from deviating and making it more stable during sliding, further improving accuracy. The left pressure plate 81 and the right pressure plate 82 are hinged together, so their tilt angle can be changed through the second adjustment structure 20, thereby adjusting the opening degree of the V-shaped lower pressure surface. This is suitable for screens with different opening degrees, making it more practical. Furthermore, using the V-shaped lower pressure surface for pressing makes it more stable and the pressure more uniform during pressing.

[0055] Both the left mounting plate 221 and the right mounting plate 222 are provided with adsorption components 21. The adsorption components 21 extend through the corresponding mounting plates to the inverted V-shaped mounting surface. The screen mounting base 2 is also provided with a telescopic drive component 23 for driving the adsorption components 21 to extend and retract relative to the inverted V-shaped mounting surface.

[0056] Using the above technical solution, both the left mounting plate 221 and the right mounting plate 222 are equipped with adsorption components 21 to make them more stable during adsorption. After the screen is processed and formed, there will be a certain space for thermal expansion and contraction, which is prone to deformation. By using the telescopic drive component 23 to drive the adsorption component 21 to extend and retract, the screen can be stretched and shaped to prevent deformation.

[0057] The first adjustment structure 10 includes a mounting plate adjustment block 101 that is slidably supported at the bottom of the left mounting plate 221 and the bottom of the right mounting plate 222, and a first adjustment screw 102 that drives the mounting plate adjustment block 101 to slide along the X-axis. The screen mounting base 2 is provided with a first guide seat 103 at the position corresponding to the mounting plate adjustment block 101 for guiding the sliding of the mounting plate adjustment block 101. The first adjustment screw 102 is rotatably mounted on the first guide seat 103 and threadedly engaged with the mounting plate adjustment block 101.

[0058] Using the above technical solution, when the mounting plate adjusting block 101 slides on the first guide seat 103, it can prevent it from rotating. At this time, the mounting plate adjusting block 101 can be driven to slide by rotating the first adjusting screw 102. The structure is simple and easy to install. Moreover, the adjustment degree can be easily controlled by adjusting the screw, which meets the accuracy requirements.

[0059] Both the left mounting plate 221 and the right mounting plate 222 are provided with telescopic drive components 23 at their bottoms. Each telescopic drive component 23 is connected to an adsorption component assembly plate 231 for assembling adsorption components 21. Each adsorption component assembly plate 231 is provided with several adsorption components 21 that slide synchronously with it. Each adsorption component 21 is a suction nozzle, which includes a flexible suction cup and an air suction hole located in the middle of the suction cup.

[0060] By adopting the above technical solution, the contact between the flexible suction cup and the screen can prevent hard collisions, thereby better protecting the screen. Then, the suction device such as the air pump is connected to the suction hole. The suction hole is located in the middle of the suction cup, which can make it more effective when used. Moreover, the suction assembly plate 231 can drive multiple suction components 21 to extend and retract at the same time, making it more stable when used and saving manufacturing costs.

[0061] The second adjustment structure 20 includes a pressure adjustment block 201 that slides against the top of the left pressure plate 81 and the right pressure plate 82, and a second adjustment screw 202 that drives the pressure adjustment block 201 to slide along the X-axis. The lower pressure seat 92 is provided with a second guide seat 203 for guiding the sliding of the pressure adjustment block 201. The second adjustment screw 202 is rotatably mounted on the second guide seat 203 and threadedly engaged with the pressure adjustment block 201.

[0062] Using the above technical solution, when the pressure adjustment block 201 slides on the second guide seat 203, it can prevent it from rotating. At this time, the pressure adjustment block 201 can be driven to slide by rotating the second adjusting screw 202. The structure is simple and easy to install. Moreover, the adjustment degree can be easily controlled by adjusting the screw, which meets the accuracy requirements.

[0063] Screen mounting base 2 has screen lifting drive components 4 on both sides. Each screen lifting drive component 4 includes a screen lifting rail 41 arranged along the Z-axis, a screen lifting frame 42 slidably arranged on the screen lifting rail 41, and a screen lifting drive component 43 that drives the screen lifting frame 42 to slide. Each screen lifting frame 42 is rotatably provided with a support shaft 431. The two support shafts 431 are concentrically arranged and locked with the screen mounting base 2 to form a support structure (the support shaft 431 and the screen mounting base 2 are preferably locked with bolts). The screen rotation drive component 5 is provided on the screen lifting frame 42 and is linked with the support shaft 431. There are two sets of screen sliding drive components 6 arranged opposite each other. Each set of screen sliding drive components 6 includes a screen smooth rail 61 arranged along the Y-axis, a slide block 62 slidably arranged on the screen smooth rail 61, and a slide block drive component 63 that drives the slide block 62 to slide. The screen lifting rail 41 and the slide block 62 correspond one-to-one and slide synchronously with each other.

[0064] By adopting the above technical solution, the screen mounting base 2 can be made more stable during lifting by two sets of screen lifting drive components 4. When the screen lifting drive component 43 drives the screen lifting frame 42 to lift and lower on the screen lifting rail 41, it can also drive the screen mounting base 2 to lift and lower together. The screen lifting rail 41 can also guide the screen lifting frame 42 during lifting and lowering, further improving stability. When the slide drive component 63 drives the slide 62 to slide along the Y-axis, it can also drive the screen lifting rail 41 to slide, thereby causing the screen mounting base 2 to slide along the Y-axis. The screen smooth rail 61 can also guide the slide 62 during sliding along the Y-axis, preventing the slide 62 from deviating. The support shaft 431 on the screen lifting frame 42 can support its opposite ends, which can increase the structural strength of the support. The screen rotation drive component 5 is set on the screen lifting frame 42 and can lift and lower together with the screen lifting frame 42, making the layout more reasonable. The screen rotation drive component 5 drives the support shaft 431 to rotate, which can drive the screen mounting base 2 to rotate, making the linkage more convenient.

[0065] The bottom frame drive assembly 7 includes a bottom frame smooth rail 71 arranged along the Y-axis and a bottom frame drive component 72 that drives the bottom frame mounting base 3 to slide on the bottom frame smooth rail 71. The bottom frame mounting base 3 is directly or indirectly slidably arranged on the bottom frame smooth rail 71.

[0066] Using the above technical solution, the bottom frame drive component 72 can drive the bottom frame mounting base 3 to slide on the bottom frame smooth rail 71. At this time, the bottom frame smooth rail 71 can act as a guide to prevent the bottom frame mounting base 3 from shifting.

[0067] Two height sensors 50 are arranged diagonally opposite each other and located at the bottom of the screen mounting base 2.

[0068] Using the above technical solution, when the bottom frame drive component 72 drives the bottom frame mounting base 3 to slide along the Y-axis to the inspection station 13, it will pass through the pre-pressing station 12. At this time, the height sensor 50 can detect the bottom frame height on the bottom frame mounting base 3, thereby determining whether the bottom frame assembly is qualified, reducing the generation of defective products. In addition, the height sensor 50 is set at an angle relative to each other, which can achieve better results and higher accuracy when shooting.
