Description

TECHNICAL FIELD

[0001] The present application relates to the production field of television, and particularly relates to a turnover and standing machine for large-sized television on a first production line. BACKGROUND

[0002] With the continuous development of economy and the continuous progress of society, people are provided with extremely rich material consumer goods, and television is one of the material consumer goods.

[0003] In the production process of large-sized television (i.e. 50-110 inches), the large-sized television is moved from a module assembly line to a test line, and the current mode for completing the process is manual mode, vacuum chuck standing machine and mechanical gantry standing machine.

[0004] However, the manual mode is very difficult for personnel to move and stand the large-sized television due to the weight of the large-sized television reaching 110 kg and the bulky volume; the vacuum chuck standing machine causes the mirror surface in the large-sized television with no frame to be displaced relative to the back plate during the turnover and standing process of the large-sized television, so that the cooperation deviation between the mirror surface and the back plate is large, and thus the process requirement cannot be met; the mechanical gantry standing machine occupies a high space and a large area, and the maintenance department is not convenient when a fault occurs, and the production rhythm cannot meet the requirement.

[0005] Therefore, there is an urgent need for a turnover and standing machine for large-sized television to overcome one or more defects. SUMMARY

[0006] The present application aims to provide a turnover and standing machine for large-sized television to solve the problems of the easily broken mirror surface and the large deviation between the mirror surface and the back plate during the turnover and standing of the large-sized television.

[0007] In order to achieve the above object, the large television turnover and standing machine is suitable for overturning and standing a large television on a first production line at a second production line, and comprises a standing foot support, a turnover frame, a supporting mechanism, a first clamping arm, a second clamping arm, a closing and opening driver and a turnover driver. The turnover frame is rotatably assembled on the standing foot support, the first clamping arm and the second clamping arm are oppositely spaced apart along a direction of a turnover center line of the turnover frame and are movably close to or away from each other, the closing and opening driver is assembled on the turnover frame and is configured to drive the first clamping arm and the second clamping arm to move close to or away from each other, the turnover driver is configured to drive the turnover frame to overturn around the turnover center line, and the supporting mechanism is assembled on the turnover frame and located between the first clamping arm and the second clamping arm and is configured to support a first side of the large television.

[0008] Compared with the prior art, the supporting mechanism, the first clamping arm, the second clamping arm, the closing and opening driver, the turnover driver and the turnover frame are cooperated, so that in the process of overturning and standing the large television on the first production line at the second production line, the first side of the large television on the first production line is supported by the supporting mechanism, and the second side and the third side of the large television on the first production line are correspondingly clamped by the first clamping arm and the second clamping arm under the cooperation of the closing and opening driver, then the turnover driver drives the turnover frame to overturn and stand the clamped large television on the second production line. Since the first to third sides of the large television are stably supported by the supporting mechanism, the first clamping arm and the second clamping arm, the turnover and standing operation of the large television with or without a frame is suitable, and in the process of overturning and standing, the displacement of the mirror relative to the back plate of the large television is effectively blocked to cause large deviation, and the use of a vacuum chuck is avoided to cause the mirror to be easily broken.

[0029] The preferred embodiments of the present application will be described below with reference to the accompanying drawings.

[0030] Please refer to Figure 1 and Figure 2 , the turning and standing machine 100 for large-sized TV sets of the present application is suitable for turning and standing the large-sized TV set 300 on the first production line 210 (for example, a module assembly line) at the second production line 220 (for example, a testing line), which comprises the standing leg frame 10, the turning frame body 20, the holding mechanism 30, the first clamping arm 40a, the second clamping arm 40b, the opening and closing driver 50 and the turning driver 60. The turning frame body 20 is rotatably assembled on the standing leg frame 10, and the standing leg frame 10 provides support for the turning frame body 20. Optionally, in Figure 1 and 3 , as an example, the standing leg frame 10 is arranged in two, which are separated in the direction of the turning center line 21 of the turning frame body 20 (for example, the left-right direction in Figure 3 ). The turning frame body 20 is located between the two standing leg frames 10, and the end of the turning frame body 20 is assembled and connected with the corresponding standing leg frame 10. This design can make the standing leg frame 10 more reliable in supporting the turning of the two ends of the turning frame body 20, and improve the smoothness and reliability of the turning of the turning frame body 20. Of course, in other embodiments, the number of standing leg frames 10 can also be other, and is not limited thereto.

[0031] Meanwhile, the first clamping arm 40a and the second clamping arm 40b are mounted relatively apart on the tilting frame 20 along the tilting center line 21 to meet the need for the first clamping arm 40a and the second clamping arm 40b to clamp the large television 300 from opposite directions. The first clamping arm 40a and the second clamping arm 40b can also move relatively closer or further apart. That is, for the first and second clamping arms 40b mounted on the tilting frame 20, at least one of them needs to slide on the tilting frame 20 to meet the need for the first and second clamping arms 40b to move relatively closer or further apart. The tension-closing actuator 50 is mounted on the tilting frame 20, and the tilting frame 20 provides support for the tension-closing actuator 50. The tension-closing actuator 50 is configured to drive the first clamping arm 40a and the second clamping arm 40b to move relatively closer or further apart, providing power for the relative movement of the first and second clamping arms 40b. The tilting actuator 60 is configured to drive the tilting frame 20 to tilt around the tilting center line 21. The supporting mechanism 30 is mounted on the flip frame 20, which provides support for the supporting mechanism 30 and can flip together with the flip frame 20. The supporting mechanism 30 is located between the first clamping arm 40a and the second clamping arm 40b. The supporting mechanism 30 is configured to support the first side 310 of the large-screen television 300, the first clamping arm 40a is configured to clamp the second side 320 of the large-screen television 300, and the second clamping arm 40b is configured to clamp the third side 330 of the large-screen television 300. (See attached diagram). Figure 1 As shown; therefore, in Figure 2 In this process, after the first clamping arm 40a, the second clamping arm 40b, and the supporting mechanism 30 have each stabilized their respective positions on the large television 300 on the first production line 210, the flipping driver 60 drives the flipping frame 20 to flip counterclockwise around the flipping center line 21. During the flipping process, because the supporting mechanism 30 supports the first side 310 of the large television 300 and prevents the large television 300 from moving from its fourth side 340 towards its first side 310, the mirror and back panel of the large television 300 do not move relative to each other during the flipping process from the first production line 210 to the second production line 220. More specifically, as follows:

[0032] like Figures 1 to 4As shown, the first and second clamping arms 40b are each slidably arranged on the turnover frame body 20, so that the first and second clamping arms 40b can each slide relative to the turnover frame body 20, so that the first and second clamping arms 40b can be actively moved closer to or away from each other; the opening and closing drive 50 is a rotary motor, and there are two rotary motors, one rotary motor drives the first clamping arm 40a to slide through the screw nut assembly 51, and the other rotary motor drives the second clamping arm 40b to slide through the screw nut assembly 52. This arrangement allows the opening and closing drive 50 to accurately and reliably drive the first and second clamping arms 40b to slide linearly on the turnover frame body 20, improving the reliability of the first and second clamping arms 40b corresponding to clamping the second side 320 and the third side 330 of the large television 300. In addition, the detailed structure of the first and second clamping arms 40b is described below.

[0033] As shown in Figure 4 and Figure 5 , the first clamping arm 40a includes a cantilever 41 and a clamping assembly 42 assembled on the cantilever 41. The clamping assembly 42 is arranged in two in the length direction of the cantilever 41 to increase the number of clamping positions for the second side 320 of the large television 300. Of course, according to actual needs, the number of clamping assemblies 42 can also be one or three, so it is not limited to Figure 5 As shown, when the first clamping arm 40a includes the cantilever 41 and the clamping assembly 42, at this time, the cantilever 41 is assembled and connected with the turnover frame body 20, and the turnover frame body 20 provides sliding support for the cantilever 41. Specifically, in Figure 5 , as an example, the cantilever 41 includes a first arm segment 411, a second arm segment 412, and a third arm segment 413 in the length direction away from the turnover frame body 20, at this time, the first arm segment 411 is assembled on the turnover frame body 20, the third arm segment 413 is upwardly offset relative to the first arm segment 411 in the height direction of the cantilever 41, the second arm segment 412 is connected between the first arm segment 411 and the third arm segment 413, and the clamping assembly 42 is assembled on the third arm segment 413; This design can raise the third arm segment 413 relative to the first arm segment 411 (i.e., the two are not equal in height), so that the height of the turnover frame body 20 can be lower than the first production line 210 (the state is shown in Figure 2 ), so that the first production line 210 does not block the turnover of the turnover frame body 20 when the large television 300 is grabbed, and cannot be turned to the position where the first and second clamping arms 40b clamp the large television 300 on the first production line 210; in addition, Figure 4As an example, the clamping assembly 42 includes a clamping block 421 and a top pressure driver 422. The clamping block 421 is mounted on the cantilever 41 (specifically, on the third arm segment 413), and the top pressure driver 422 is mounted on the cantilever 41. Of course, it can also be mounted on the clamping block 421 as needed. The output end 4221 of the top pressure driver 422 can move linearly in the height direction of the cantilever 41. A top pressure structure 423 is mounted on the output end 4221 of the top pressure driver 422. Correspondingly, the clamping block 422 is provided with a pressure-adjusting structure 424 that cooperates with the top pressure structure 423 in the height direction of the cantilever 41, so that under the drive of the top pressure driver 422, the top pressure structure 423 and the pressure-adjusting structure 424 jointly clamp or release the second side 320 of the large television 300. More specifically, in Figure 4 As an example, the clamping block 421 has a cross-section in the shape of a "コ" (ko), which makes it easier for the clamping block 421 to move under the drive of the opening and closing actuator 50 to a position that supports the second side 320 of the large television 300 from below and laterally blocks and positions the second side 320. This state is visible. Figure 4 As shown, at this time, the top pressure structure 423, driven by the top pressure actuator 422, approaches the pressure distribution structure 424, so that the top pressure structure 423 and the pressure distribution structure 424 jointly clamp the second side 320; in addition, the third arm segment 413 is parallel to the first arm segment 411. For example, the top pressure actuator 422 is a cylinder or a hydraulic cylinder, but is not limited thereto.

[0034] like Figure 4 and Figure 6 As shown, the second clamping arm 40b includes a cantilever 43 and clamping components 44 mounted on the cantilever 43. Two clamping components 44 are arranged spaced apart along the length of the cantilever 43 to increase the number of clamping positions on the third side 320 of the large-format television 300. Of course, depending on actual needs, the number of clamping components 44 can also be one or three, therefore... Figure 6 The illustration is for illustrative purposes only; furthermore, when the second clamping arm 40b includes a cantilever 43 and a clamping assembly 44, the cantilever 43 is assembled and connected to the tilting frame 20, and the tilting frame 20 provides sliding support for the cantilever 43. Specifically, in Figure 6 In this example, the cantilever 43, along its length away from the tilting frame 20, sequentially includes a first arm segment 431, a second arm segment 432, and a third arm segment 433. The first arm segment 431 is mounted on the tilting frame 20, and the third arm segment 433 is offset upwards relative to the first arm segment 431 in the height direction of the cantilever 43. The second arm segment 432 is obliquely connected between the first arm segment 431 and the third arm segment 433, and the clamping assembly 44 is mounted on the third arm segment 433. This design allows the third arm segment 433 to be raised relative to the first arm segment 431 (i.e., they are not at the same height), thus allowing the height of the tilting frame 20 to be lower than the first production line 210 (see status).Figure 2 (As shown), to prevent the second production line 220 from blocking the flipping frame 20 from flipping when the large television 300 is being gripped, so that the first and second gripping arms 40b come to the position to grip the large television 300 on the first production line 210; also, in Figure 4 As an example, the clamping assembly 44 includes a clamping block 441 and a top pressure driver 442. The clamping block 441 is mounted on the cantilever 43 (specifically, on the third arm segment 433), and the top pressure driver 442 is mounted on the cantilever 43. Of course, it can also be mounted on the clamping block 441 as needed. The output end 4421 of the top pressure driver 442 can move linearly in the height direction of the cantilever 43. A top pressure structure 443 is mounted on the output end 4421 of the top pressure driver 442. Correspondingly, the clamping block 442 is provided with a pressure matching structure 444 that cooperates with the top pressure structure 443 in the height direction of the cantilever 43, so that under the drive of the top pressure driver 442, the top pressure structure 443 and the pressure matching structure 444 jointly clamp or release the third side 330 of the large television 300. More specifically, in Figure 4 As an example, the clamping block 441 has a cross-section in the shape of a "コ" (ko), which makes it easier for the clamping block 441 to move under the drive of the opening and closing actuator 50 to a position that supports the third side 330 of the large television 300 from below and laterally blocks and limits the third side 330. This state is visible. Figure 4 As shown, at this time, the top pressure structure 443, driven by the top pressure actuator 442, approaches the pressure distribution structure 444, so that the top pressure structure 443 and the pressure distribution structure 444 jointly clamp the third side 330; in addition, the third arm segment 433 is parallel to the first arm segment 431. For example, the top pressure actuator 442 is a cylinder or a hydraulic cylinder, but is not limited thereto.

[0035] like Figure 1 , Figure 2 and Figure 7 As shown, four supporting mechanisms 30 are arranged at intervals along the direction of the rotation center line 21 of the rotating frame 20 to increase the number of supporting positions of the supporting mechanisms 30 on the first side 310 of the large television 300. Of course, depending on actual needs, the number of supporting mechanisms 30 can also be one, two, three or five. Each supporting mechanism 30 includes a mechanism frame 31 mounted on the rotating frame 20, a supporting driver 32 mounted on the mechanism frame 31, and a supporting block 33 for supporting the large television 200. The output end 321 of the supporting driver 32 can move linearly. The supporting block 33 is mounted on the output end 321 of the supporting driver 32. The supporting block 33 has a supporting part 331 and a side stop 332. The side stop 332 and the supporting part 331 are arranged at an angle and together form a notch 333, as shown in the figure. Figure 7The design makes the supporting block 33 better support the first side 310 of the large TV 300 on the first production line 210 from below while blocking the first side 310 laterally under the drive of the supporting driver 32, achieving the purpose of supporting and positioning the large TV 300 on the first production line 210 before turning over. For example, the supporting driver 32 can be a pneumatic cylinder or a hydraulic cylinder, but is not limited thereto.

[0036] As shown in Figure 1 and Figure 2 , and Figure 8 and Figure 9 , the large TV turning machine 100 of the present application further comprises a centering mechanism 70 located beside the side of the first production line 210 away from the turning frame 20, and the centering mechanism 70 is configured to push the fourth side 340 of the large TV 300 on the first production line 210; wherein the centering mechanism 70 comprises a standing frame 71, a servo motor 72, a reducer 73, a linear module 74, a moving seat 75, a lifting driver 76 and a pushing structure 77. The servo motor 72, the reducer 73 and the linear module 74 are installed side by side at the top of the standing frame 71, so that their arrangement on the standing frame 71 is more compact; the moving seat 75 is cross-mounted on the linear module 74; the servo motor 72 drives the moving seat 75 to move through the reducer 73 and the linear module 74; the lifting driver 76 is arranged outside the opposite sides of the linear module 74 and mounted on the moving seat 75, the output end 761 of each lifting driver 76 is arranged downward and can move linearly, and the pushing structure 77 is mounted on the output end 761 of each lifting driver 76; this design can increase the position of the large TV 300 by pushing the fourth side 340 to make the first side 310 slide to the position supported by the supporting part 331 and positioned laterally by the lateral blocking part 332, as shown in Figure 7 For example, the lifting driver 76 can be a pneumatic cylinder or a hydraulic cylinder, but is not limited thereto.

[0037] As shown in Figures 1 to 2 , and Figures 10 to 11As shown, the large television set turnover and standing machine 100 of the present application further comprises a pushing-back mechanism 80 located beside the side of the second production line 220 away from the turnover frame body 20, the pushing-back mechanism 80 comprises a standing frame 81, a pushing-back driver 82, a pushing-back guide rod 83, a pushing-back guide sleeve 84, a roller 85 and a mounting bracket 86. The pushing-back driver 82 is assembled on the standing frame 81, the output end 821 of the pushing-back driver 82 is inclined up and down in the direction close to the second production line 220, and the output end 821 of the pushing-back driver 82 can also move linearly; the mounting bracket 86 is fixedly connected with the output end 821 of the pushing-back driver 82; the end of the roller 85 is rotatably assembled on the mounting bracket 86, and the mounting bracket 86 provides support for the rolling of the roller 85; the pushing-back guide rod 83 is arranged beside the opposite sides of the output end 821 of the pushing-back driver 82 respectively, so that the opposite sides of the output end 821 are each provided with the pushing-back guide rod 83, thereby ensuring the uniformity of the force distribution of the pushing-back driver 82 on the mounting bracket 86; each pushing-back guide rod 83 corresponds to a pushing-back guide sleeve 84, and each pushing-back guide rod 83 is arranged in the corresponding pushing-back guide sleeve 84, the pushing-back guide sleeve 84 is fixed on the standing frame 81, and the mounting bracket 86 is also fixedly connected with each pushing-back guide rod 83. During the process of turning over the large television set 300 from the first production line 210 and standing it on the second production line 220, the pushing-back driver 82 first drives the mounting bracket 86 to slide together with the roller 85 in the direction close to the turnover frame body 20; after the roller 85 abuts against the roller of the turned-over large television set 300, the pushing-back driver 82 drives the mounting bracket 86 to slide together with the roller 85 in the direction away from the turnover frame body 20, so that the large television set 300 is placed on the second production line 220 under the coordination of the roller 86. For example, the pushing-back driver 82 can be a pneumatic cylinder or a hydraulic cylinder, but is not limited thereto.

[0038] As shown, Figure 3 The turnover driver 60 is located beside one standing foot 10, and the turnover driver 60 drives the turnover frame body 20 to turn over through the speed reducer 61, so as to increase the ability of the turnover driver 60 to drive the turnover frame body 20 to turn over through the speed reducer 61. For example, the turnover driver 60 can be a servo motor.

[0039] The working principle of the large television set turnover and standing machine of the present application will be described in combination with the drawings:

[0040] On the first production line 210, after the mirror is covered by the back plate, the front frame is clamped and screws are screwed into the vertical machine process, the large TV 300 is carried to the position by the tool plate; after being positioned, the centering mechanism 70 pushes the fourth side 340 of the large TV 300 on the first production line 210, so that the large TV 300 is positioned, the supporting mechanism 30 lifts and supports the first side 310 of the large TV 300, and the first clamping arm 40a and the second clamping arm 40b correspondingly clamp the second side 320 and the third side 330 of the large TV 300 on the first production line 210 under the drive of the opening and closing driver 50; then, under the drive of the turnover driver 60 to the turnover frame body 20, the large TV 300 on the first production line 210 is held and separated from the tool plate, and the tool plate separated from the large TV 300 flows away; then, after the held large TV 300 is turned over 120 degrees under the drive of the turnover driver 60 to the turnover frame body 20, it falls on the test tool jig of the second production line 220, at this time, the first clamping arm 40a and the second clamping arm 40b loosen the clamping of the large TV 300.

[0041] Compared with the prior art, with the cooperation of the supporting mechanism 30, the first clamping arm 40a, the second clamping arm 40b, the opening and closing driver 50, the turnover driver 60 and the turnover frame body 20, in the process of turning over and standing the large TV 300 on the first production line 210, first, the supporting mechanism 30 supports the first side 310 of the large TV 300 on the first production line 210, so that the first clamping arm 40a and the second clamping arm 40b correspondingly clamp the second side 320 and the third side 330 of the large TV 300 on the first production line 210 under the cooperation of the opening and closing driver 50; then, the turnover driver 60 drives the turnover frame body 20 to turn over and stand the clamped large TV 300 on the second production line 220; since the supporting mechanism 30, the first clamping arm 40a and the second clamping arm 40b are used to stabilize the first to third sides 330 of the large TV 300, it is suitable for turning over and standing the large TV 300 with or without a frame, and can effectively block the displacement of the mirror in the large TV 300 relative to the back plate during turning over and standing, thereby avoiding the use of a vacuum chuck which can easily break the mirror; therefore, the large TV turnover and standing machine 100 can solve the problems of easy breakage of the mirror and excessive deviation between the mirror and the back plate during turning over and standing of the large TV, and has the advantages of small occupied space and easy maintenance compared with the mechanical gantry standing machine.

[0042] It should be noted that since the mirror of the large TV 300 is glass, in order to prevent damage to the glass, the pressure matching structure 424 and the top pressure structure 423 of the first clamping arm 40a, the pressure matching structure 444 and the top pressure structure 443 of the second clamping arm 40b, the supporting part 331 and the side blocking part 332 of the supporting block 33, the roller 85 in the push-back mechanism 80, and the pushing structure 77 in the centering mechanism 70 are all provided with a flexible material buffer structure.

[0043] The above-described embodiments are merely intended to facilitate the understanding and implementation of the present application by those skilled in the art, and should not be used to limit the scope of the present application. Any equivalent changes made in accordance with the patent scope of the present application should still fall within the scope of the present application.
