DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and do not limit the scope of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The specific embodiments are as follows: Embodiment 1, as Figure 1-15 As shown, a mechanism for accurately assembling a display inner screen with multiple acupuncture points is provided. The assembly mechanism includes an inner screen supply module 100, a robot module 200, an inner screen positioning module 300, a pick-and-place inner screen module 400, and a product positioning module 500.

[0022] The inner screen module 100 is used to provide the inner screen, including the inner screen streamline 101, the material tray 102, the stop cylinder 103 and the positioning cylinder 104. At the manual loading position, the staff puts the material tray 102 carrying multiple inner screens into the inner screen streamline 101, and the inner screen streamline 101 drives the unloading material tray 102 to move to the specified position, the stop cylinder 103 extends upward to stop the material tray, and the positioning cylinder 104 extends horizontally to press the material tray 102 against one side of the inner screen streamline 101 for positioning and clamping, so as to facilitate the robot module 200 to pick up the inner screen; and after the inner tray on the material tray 102 is picked up, the stop cylinder 103 and the positioning cylinder 104 shrink, and the empty material tray 102 returns to the inner screen streamline 101 and moves to the manual unloading position, and a staff member takes away the empty material tray 102.

[0023] The manipulator module 200 uses a manipulator in the prior art, which can imitate certain movements and functions of human hands and arms, and is an automatic operating device for grabbing, moving objects or operating tools according to a fixed program. A plurality of spring suction cups are arranged at the movable end of the manipulator, which can pick up a plurality of inner screens from the material tray 102 at one time and place them in the inner screen positioning module 300. The spring suction cup can reduce the impact of one of the multiple inner screens not being sucked in place during the suction process, which causes the remaining inner screens to be affected during the suction process, and plays a certain buffering role.

[0024] The inner screen positioning module 300 is used to temporarily place the inner screen and adjust the inner screen to a suitable position. The inner screen positioning module 300 includes an inner screen base 301 and an inner screen positioning component. A plurality of inner screen acupoints 302 are provided on the inner screen base 301, the number of which is the same as the number of spring suction cups on the manipulator module 200, and the positions correspond. The inner screen positioning component is used to synchronously adjust the position and position of the inner screen on the inner screen base 301.

[0025] The product positioning module 500 includes a product carrier 501 and a product positioning component, and also includes a product flow line 509, a blocking cylinder 510 and a lifting cylinder 511. A plurality of product points 502 are arranged on the product carrier 501, and the number is the same as the number of the inner screen points 302 on the inner screen base 301, and the positions correspond one to one. After placing a plurality of products on the product carrier 501, it enters the product flow line 509, and moves to the position corresponding to the product positioning component under the action of the product flow line 509, and the blocking cylinder 510 lifts and stops the product carrier 501, and then the lifting cylinder 511 lifts and lifts the product carrier 501 away from the product flow line 510, and the positions of the plurality of products are adjusted and positioned synchronously under the action of the product positioning component, so as to facilitate the precise alignment of the positions of the plurality of products with the positions of the plurality of inner screens one by one, and complete the precise assembly of the plurality of products at one time; after the assembly is completed, the lifting cylinder 511 and the blocking cylinder 510 retract, and the product carrier 501 returns to the product flow line 510 and continues to flow downward.

[0026] The inner screen module 400 drives three KK modules to move along the X, Y, and Z axes through three servo motors, and then drives multiple inner screen suction components to move along the X, Y, and Z axes. Buffer springs are arranged in the inner screen suction components, and the number is the same as that of the spring suction cup. Based on this, the inner screen module 400 sucks multiple inner screens from the inner screen positioning module 300 at one time through the inner screen suction component, and moves to the product acupoint 502 of the product positioning module 500, and relies on the downward pressure of the KK module driven by the Z-axis motor to complete the assembly of the inner screen and the product. During the assembly process, the buffer spring plays a certain pressing buffer to prevent the inner screen from being crushed by excessive downward pressure. At the same time, the pressing buffer cylinder is always in an extended state, which reduces the occurrence of one of the multiple inner screens not being assembled in place during the assembly process, causing the remaining inner screens to be affected during the assembly process and plays a certain buffering role.

[0027] It should be noted that the inner screen positioning assembly and the product positioning assembly both include a Y-direction side push member, a Y-direction linkage member, a Y-direction driving member, an X-direction side push member, an X-direction linkage member and an X-direction driving member. In the corresponding module, the Y-direction side pusher is arranged at the end of the corresponding acupuncture point, and can move back and forth along the Y direction, and can push and adjust the position of the inner screen and / or the product in the Y direction during the process; multiple Y-direction side pushers are connected to the Y-direction linkage member at the same time, and the Y-direction linkage member is driven by the Y-direction driving member, so that the Y-direction linkage member can drive multiple Y-direction side pushers to move synchronously to adjust the position of the inner screen and / or the product in the Y direction; the X-direction side pusher is arranged on one side of the corresponding acupuncture point, and can move back and forth along the X direction, and can push and adjust the position of the inner screen and / or the product in the X direction during the process; multiple X-direction side pushers are connected to the X-direction linkage member at the same time, and the X-direction linkage member is driven by the X-direction driving member, so that the X-direction linkage member can drive multiple X-direction side pushers to move synchronously to adjust the position of the inner screen and / or the product in the X direction; and then, the synchronous adjustment of multiple products and / or inner screens can be realized to ensure that the positions of the inner screen and the product are accurately aligned one by one before assembly, so as to facilitate the accurate assembly of multiple products at one time, improve assembly efficiency, and reduce the defective rate.

The inner screen Y-direction side thrust member 303 includes a side thrust block 3031, a side thrust rod 3032, and a first elastic member 3033. More specifically, the side thrust block 3031 is vertically connected to the Y-direction side thrust rod 304, the side thrust rod 3032 is retractably connected to the end of the side thrust block 3031 away from the Y-direction side thrust rod 304, and the side first elastic member 3033 is arranged between the thrust rod 3032 and the side thrust block 3031 to provide rebound and buffering effects. In this embodiment, the inner screen Y-direction cylinder 305 is connected to the inner screen base 301, and the Y-direction side push rod 304 is connected to the telescopic end of the inner screen Y-direction cylinder 305 to realize the adjustable connection between the Y-direction side push rod 304 and the Y-direction side push member 303 on the inner screen base 301.

[0029] Further, in the inner screen positioning assembly 300, the X-direction side pusher adopts a "[" block 306; the X-direction linkage adopts an X-direction side push rod 307; and the X-direction driving member adopts an inner screen X-direction cylinder 308. More specifically, the "[" blocks 306 are all arranged on the left side of the inner screen acupuncture point 302, the U-shaped ends of the "[" blocks 306 push the inner screen, and a connecting block is arranged at the bottom of the "[" block 306. The connecting block is suspended to the space below the inner screen acupuncture point 302 and is connected to the X-direction side push rod 307 arranged in the space below the inner screen acupuncture point 302. The left end of the X-direction side push rod 307 is connected to the telescopic end of the inner screen X-direction cylinder 308, and the inner screen X-direction cylinder 308 is connected to the left side of the inner screen base 301, so as to realize the adjustable connection between the "[" block 306 and the X-direction side push rod 307 and the inner screen base 301, and realize the synchronous adjustment of multiple inner screens on the inner screen base 301.

[0030] Further, in the product positioning module 500, the product positioning component and the product carrier 501 are separately arranged, and the product positioning component is connected to the product flow line 509 through a bracket and does not move with the product flow line 509. In the product positioning module 500, the product positioning component also includes a bottom plate 508, and the Y-direction side thrust member, the Y-direction linkage member, the Y-direction driving member, the X-direction side thrust member, the X-direction linkage member and the X-direction driving member are all arranged on the bottom plate 508. The Y-direction side thrust member and the X-direction side thrust member both use a "￢" type block 503, the Y-direction linkage member uses a Y-direction side thrust plate 504, the X-direction linkage member uses an X-direction side thrust plate 506, the Y-direction driving member uses a product Y-direction cylinder 505, and the X-direction driving member uses a product X-direction cylinder 507. More specifically, the bottom plate 508 is provided with bottom plate openings 5081 corresponding one-to-one to the product points 502 on the product carrier 501, and the X-axis side push plate 506 is provided with side push plate openings 5061 corresponding one-to-one to the product points 502 on the product carrier 501. The bottom plate openings 5081 and the side push plate openings 5061 are both larger than the products for allowing the products to pass through.

[0031] In this embodiment, the product Y-direction cylinder 505 is connected to the base plate 508, the Y-direction side push plate 504 is located on the upper side of the base plate 508 and connected to the telescopic end of the product Y-direction cylinder 505, and a plurality of driving rods corresponding to the Y-direction side push members are cantilevered from the side of the Y-direction side push plate 504 close to the base plate opening 5081, and the driving rods are used to drive the "￢"-shaped block 503; the "￢"-shaped block 503 serving as the Y-direction side push member is provided at the end of the base plate opening 5081, a groove 5031 is provided at the top of the "￢"-shaped block 503, and a protrusion is provided on the lower side of the driving rod to protrude into the groove 5031, so that the Y-direction side push plate 504 can synchronously drive the multiple "￢"-shaped blocks 503 to move, and then the multiple "￢"-shaped blocks 503 can synchronously push the product to realize Y-direction synchronous adjustment.

[0032] In this embodiment, a "￢"-shaped block 503 serving as an X-direction side thrust member is arranged on the left side of the product acupoint 502, and two "￢"-shaped blocks 503 are arranged on the left side of each product acupoint 502, and a groove 5031 is arranged on the top of the "￢"-shaped block 503; the X-direction side thrust plate 506 is arranged above the bottom plate 508, and is connected to the telescopic end of the product X-direction cylinder 507 connected to the bottom plate 508, the side thrust plate opening 5061 corresponds one-to-one to the bottom plate opening 5081, and two protrusions 5062 are arranged on the lower side surface of the X-direction side thrust plate 506 and on the left side of each side thrust plate opening 5061, and the protrusion 5062 is cantilevered in the groove 5031, so as to realize the synchronous driving of multiple "￢"-shaped blocks 503, and then the X-direction synchronous adjustment of multiple products.

[0034] Furthermore, a second elastic member 5032 is provided on a side of the “￢”-shaped block 503 away from the corresponding product to play a buffering and rebounding role.

[0035] Embodiment 2, as Fig.10 As shown, a mechanism for accurately assembling a display inner screen at multiple acupoints is different from Example 1 in that a Y-axis limit block 5082 acting on the Y-axis side push plate and an X-axis limit screw 5083 acting on the X-axis side push plate are provided on the bottom plate. The positions of the Y-axis limit block 5082 and the X-axis limit screw 5083 are both adjustable and are used to adjust the stroke of the product Y-axis cylinder and the product X-axis cylinder to adapt to products of different models or categories. Other structures are not described here.

[0036] Embodiment 3, as Figure 1-15 As shown, based on the same inventive concept as the above-mentioned mechanism for accurately assembling a display inner screen with multiple acupoints, the present invention also provides a method for accurately assembling a display inner screen with multiple acupoints, the method comprising the following steps: S1: In the inner screen supply module 100, the staff puts the material tray 102 carrying multiple inner screens into the inner screen flow line 101 at the loading position. When the material tray 102 moves to the set position on the inner screen flow line 101, it is stopped by the stop cylinder 103, and the material tray 102 is stationary relative to the inner screen flow line 101. The material tray 102 is pressed tightly against one side of the inner screen flow line 101 by the positioning cylinder 104, so that the robot module 200 can absorb the inner screen. S2: The robot module 200 uses multiple spring suction cups thereon to suck up multiple inner screens at one time on the clamped material tray 102, and moves the inner screens to place them in the inner screen acupoints 302 of the inner screen positioning module 300; S3: After the robot module 200 places the multiple inner screens on the inner screen positioning module 300, the inner screen Y-direction cylinder 305 starts to drive the Y-direction side push rod 304 to move along the Y direction, and the Y-direction side push rod 304 drives the multiple inner screen Y-direction side pushers 303 to synchronously move and push the inner screen, so that the multiple inner screens are synchronously close to the bottom of the inner screen acupuncture point 302; then, the inner screen X-direction cylinder 308 starts to drive the X-direction side push rod 307 to move along the X direction, and the X-direction side push rod 307 drives the multiple "["-shaped blocks to move to the right, so that the multiple inner screens are synchronously close to the right side of the inner screen acupuncture point 302, so as to clamp and position the multiple inner screens; and after the inner screen module 400 picks up the inner screen that is clamped and positioned on the inner screen positioning module 300, the inner screen X-direction cylinder 308 and the inner screen Y-direction cylinder 305 return in sequence; S4: In the product positioning module 500, the product carrier 501 carrying the same number of products as those on the inner screen positioning module 300 enters the product flow line 509. When the product carrier 501 moves to the position aligned with the product positioning component, the blocking cylinder 510 extends to stop the product carrier 501, and then the lifting cylinder 511 extends upward to lift the product carrier 501, so that the product carrier 501 is pressed upward against the product positioning component; then, the product Y-direction cylinder 505 is started to drive the Y-direction side push plate 504 moves along the Y direction, and the Y-direction side push plate 504 drives multiple "￢"-shaped blocks 503 to move synchronously by hooking the groove 5031 with the protrusion, and multiple products are close to the bottom of the product acupoint 502. Then, the product X-direction cylinder 507 is started to drive the X-direction side push plate 506 to move along the X direction, and the protrusion 5062 hooks the groove 5031 to drive multiple "￢"-shaped blocks 503 to move synchronously, and multiple products are close to the right side of the product acupoint 502, so as to clamp and position multiple products; S5: The inner screen placement module 400 is started, and multiple inner screens are sucked from the inner screen positioning module 300 at one time by using the inner screen suction component, and moved to the product acupoint 502 of the product positioning module 500, and the assembly of the inner screen and the product is completed by relying on the downward pressure of the KK module driven by the Z-axis motor; since the position of the inner screen is adjusted by the inner screen positioning component in the inner screen positioning module 300, and the position of the product is adjusted by the product positioning component at the product positioning module 500, the inner screen and the product are in a state of precise one-to-one correspondence before assembly, so as to realize the precise assembly of multiple products at one time, which improves the assembly efficiency and reduces the defective assembly rate.

[0037] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
