[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, through the cooperation of the lifting assembly and the feeding and discharging assembly, the TV circuit board sent by the conveyor belt is pulled into the feeding and discharging assembly, and the lifting assembly drives the feeding and discharging assembly and the clamping and flipping assembly inside it to rise. The clamping and flipping assembly drives the TV circuit board to rise, and the cooperation of the clamping and flipping assembly and the lifting assembly is used to clamp and fix the circuit board. After rising to a certain height, the clamping and flipping assembly drives the TV circuit board to flip, and the flipped circuit board is sent back above the support table. Through the action of the lifting assembly and the feeding and discharging assembly, the next circuit board is received and the flipped circuit board is sent to the conveyor belt on the left and sent to the next soldering process, thus realizing automatic flipping and continuous processing.

[0019] 2. In the present invention, the electric telescopic rod and the cross slider drive the support plate to move left and right at the upper end of the support table. Through the action of the pushing component between the two support plates, the TV circuit board sent by the conveyor belt on the right is received between the support plates, and it is pushed above the support table by the pushing component. The travel switches arranged at the four corners are used to drive the TV circuit board to stay above the support table by the action of the electric telescopic rod, which is convenient for subsequent flipping.

[0020] 3. After the flipping of the present invention is completed, the new TV circuit board will push open the pushing component and enter the support plate, and push the flipped circuit board to the left. When the support plate moves to the right under the action of the electric telescopic rod, the pushing component on the left will cross the flipped circuit board and push it into the conveyor belt on the left during the reset process, realizing automatic feeding and discharging.

[0021] 4. The present invention utilizes the functions of the first motor and the winding disc to drive the T-shaped slider to slide in the vertical rod through the cable, and then promotes the support plate to rise by the action of the T-shaped slider on the support plate. The clamping and flipping assembly installed on the cross slider clamps and fixes the TV circuit board during the lifting process, thereby avoiding the position deviation, collision or falling off of the TV circuit board due to the centrifugal force during the flipping process, reducing the damage to the circuit board during the flipping process, optimizing the processing flow, and thus ensuring the product quality.

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Example 1, as Figure 1 shown, a flipping device for a TV welding production line includes a conveying table 1. Four support legs 3 are fixedly connected to the lower end of the conveying table 1 in a rectangular distribution. Conveyor belts 4 are fixedly installed on the upper end of the conveying table 1 symmetrically left and right. A flipping structure 5 is fixedly installed in the middle of the upper end of the conveying table 1. The front end of the flipping structure 5 and the upper end of the conveying table 1 are fixedly connected with a controller 2 together.

[0035] It should be particularly noted that the above-mentioned controller 2 is a conventional control device, and this structure has been widely used in the prior art. In the present invention, it is only used to receive sensor and switch signals to control the start and stop of telescopic devices and driving devices, and its internal structure, operating principle, wiring and control method will not be elaborated further;

[0036] Synchronously, the above-mentioned conveyor belt 4 is composed of a bearing rotating bracket, a pulley installed in the bearing bracket, a belt wound around the outer surface of the pulley, and an electric mechanism for driving the pulley. It is a conventional conveying mechanism. In the present invention, it is only used to provide the TV circuit board for the flipping structure 5 and send out the flipped circuit board, and its internal structure, operating principle, wiring and control method will not be elaborated further.

[0037] Furthermore, in order to flip the TV circuit board to be welded, refer to Figure 2, the flipping structure 5 includes a support platform 51 fixedly connected to the upper end of the conveying platform 1. In the middle of the upper end of the support platform 51, there is a feeding and discharging component 52. At the upper end of the support platform 51, a lifting component 53 is arranged jointly with the front and rear ends of the feeding and discharging component 52. On the inner surface of the feeding and discharging component 52, clamping and flipping components 57 are symmetrically arranged front and rear. Four travel switches 54 are fixedly connected in a rectangular distribution at the upper end of the support platform 51. At the upper end of the support platform 51, relay wheels 55 are rotatably connected symmetrically left and right.

[0038] The support platform 51 arranged at the upper end of the conveying platform 1 is used to carry the TV circuit board sent by the conveyor belt 4 on the feeding side. At this time, the upper side of the material has been welded. After being flipped by the flipping structure 5, the un-welded side is placed on the upper side and sent into the next process through the conveyor belt 4 on the left for continuous welding, thus realizing continuous processing.

[0039] During the operation of this embodiment, through the cooperation of the lifting component 53 and the feeding and discharging component 52, the TV circuit board sent by the conveyor belt 4 is pulled into the feeding and discharging component 52. Through the action of the lifting component 53 on the feeding and discharging component 52, the feeding and discharging component 52 and the clamping and flipping components 57 inside it are driven to rise. The clamping and flipping components 57 drive the TV circuit board to rise, and the clamping and flipping components 57 and the lifting component 53 are used to clamp and fix the circuit board. After rising to a certain height, the clamping and flipping components 57 drive the TV circuit board to flip, and the flipped circuit board is sent back above the support platform 51. Through the action of the lifting component 53 and the feeding and discharging component 52, the next circuit board is received and the flipped circuit board is sent onto the conveyor belt 4 on the left and sent into the next welding process, thus realizing automatic flipping and continuous processing.

[0040] Embodiment 2: On the basis of Embodiment 1, through the action of the electric telescopic rod 5352 and the cross slider 5351, the support plate 521 is driven to move left and right at the upper end of the support platform 51. Through the action of the pushing component 524 between the two support plates 521, the TV circuit board sent by the conveyor belt 4 on the right is received between the support plates 521 and pushed above the support platform 51 by the pushing component 524. By using the travel switches 54 arranged at the four corners, the electric telescopic rod 5352 is used to drive the TV circuit board to stay above the support platform 51, which is convenient for subsequent flipping;

[0041] After flipping, the new TV circuit board will push open the pushing component 524 and enter the support plate 521, and push the flipped circuit board to the left. When the support plate 521 moves to the right under the action of the electric telescopic rod 5352, the pushing component 524 on the left will cross over the flipped circuit board and push it into the conveyor belt 4 on the left during the reset process, realizing automatic feeding and discharging.

[0042] Specifically, to access the TV circuit board from one side of the conveyor belt 4 and send out the flipped circuit board from the other side, refer to Figure 3 , the feeding and discharging component 52 includes two support plates 521 that are symmetrically distributed left and right and slidably connected to the upper end of the support table 51. At the mutually approaching ends of the two support plates 521, two pushing components 524 that are symmetrically distributed front and back are jointly provided. Cross-shaped sliding grooves 523 that are slidably connected to the support legs 3 are formed on the inner surfaces of the two support plates 521.

[0043] Further, to drive the support plate 521 to move left and right, refer to Figure 4 , at the end of the T-shaped slider 535 close to the support plate 521, a cross-shaped slider 5351 that is slidably connected to the inner surface of the cross-shaped sliding groove 523 is fixedly connected. At the right end of the cross-shaped slider 5351, an electric telescopic rod 5352 that is fixedly connected to the right part of the inner surface of the support plate 521 is fixedly connected.

[0044] Further, to limit the moving stroke of the support plate 521, refer to Figure 5 , buffer grooves 522 are symmetrically formed front and back at the end of the support plate 521 away from the pushing component 524. Spring buffer blocks 525 corresponding to the horizontal position of the driving rod of the travel switch 54 are fixedly installed on the inner surfaces of the two buffer grooves 522.

[0045] It should be specifically noted that the above-mentioned travel switch 54 is a conventional travel switch, which is a mature device in the prior art. When an object touches its driving rod, it will emit a signal, thereby controlling the driving device to run in reverse to drive the object to move in reverse, so as to realize the control of the moving stroke. It is a mature prior art. In the present invention, only its stroke for the support plate 521 is used for limitation, and its specific wiring, control method, operating principle and internal structure will not be shown and described in detail.

[0046] Through the action of the travel switch 54 and the controller 2, the extension and retraction of the electric telescopic rod 5352 are controlled. By using the action of the electric telescopic rod 5352 and the cross-shaped slider 5351, the support plate 521 can be driven to move left and right above the support table 51. The motor in the conveyor belt 4 is also controlled by the controller 2 and can intermittently feed materials above the support table 51. The materials will enter above the support table 51 through the relay wheel 55 and push open the right pushing component 524 to enter between the two support plates 521;

[0047] When the support plate 521 moves to the right, the pusher component 524 on the right will move to the right following the support plate 521 until it completely passes over the TV circuit board. The spring buffer block 525 contacts the first travel switch 54, and the electric telescopic rod 5352 retracts. At this time, the pusher component 524 on the right resets, and under the continuous retraction of the electric telescopic rod 5352, it pushes the TV circuit board towards the middle of the support table 51 until the left spring buffer block 525 contacts the first travel switch 54, the TV circuit board reaches the predetermined position, and the cross slider 5351 resets;

[0048] When there is a circuit board that has been flipped between the two support plates 521, the newly incoming material will push the flipped circuit board backward. When the support plate 521 moves to the right, the pusher component 524 on the left will be pushed open by the circuit board until it completely passes over the flipped circuit board. During the reset process of the support plate 521, the pusher component 524 on the left will push the flipped circuit board into the left conveyor belt 4 and send it out via the left conveyor belt 4.

[0049] Furthermore, to achieve one-way feeding and discharging, refer to Figure 6 and Figure 7 The pusher component 524 includes a flap 5241 and a T-shaped groove 5242 opened at one end of the support plate 521 close to the flap 5241. Both the front and rear ends of the flap 5241 are fixedly connected with a central shaft 5243 rotatably connected to the inner surface of the adjacent T-shaped groove 5242. On the side of both central shafts 5243 away from the flap 5241, there is fixedly connected a sector plate 5244 rotatably connected to the inner surface of the adjacent T-shaped groove 5242, and a stopper 5245 is fixedly connected to the inner surface of the central shaft 5243.

[0050] Furthermore, to limit the flipping direction and angle of the flap 5241, refer to Figure 7 The sector plate 5244 is in a sector shape, and an arc-shaped groove 5247 is opened on its sector outer surface. An arc-shaped spring 5246 fixedly connected to the stopper 5245 is fixedly connected to the inner surface of the arc-shaped groove 5247. The flap 5241 can only rotate to the left under the limitation of the T-shaped groove 5242 and the stopper 5245.

[0051] The flap 5241 rotates around the axis of the central shaft 5243. However, the sector plate 5244 is an incomplete circle, and its rotation trajectory is restricted by the stopper 5245 fixed in the T-shaped groove 5242, so it can only rotate to the right and the maximum rotation angle is ninety degrees;

[0052] When the TV circuit board enters the range of the support plate 521, it will push the flap 5241 to flip to the upper part of the circuit board until the TV circuit board is out of the range of the conveyor belt 4. At this time, the circuit board is in a position slightly to the right side of the support platform 51. When the support plate 521 moves to the right under the action of the electric telescopic rod 5352, the flap 5241 will gradually move to the right until it completely passes over the circuit board. At this time, the flap 5241 is reset to a vertical state under the action of the arc spring 5246, and during the movement of the support plate 521 to the left, it pushes the circuit board to move to the left synchronously, thereby realizing automatic material connection.

[0053] Embodiment 3: Based on Embodiment 2, this embodiment further utilizes the action of motor 1 534 and winding disk 533 to pull T-shaped slider 535 to slide in vertical pole 531 through cable 532, and then utilizes the action of T-shaped slider 535 on support plate 521 to cause support plate 521 to rise, and utilizes clamping and flipping assembly 57 installed on cross slider 5351 to clamp and fix the TV circuit board during the lifting process, thereby avoiding the position displacement, bump or falling off of the TV circuit board due to centrifugal force during the flipping process, reducing the damage to the circuit board during the flipping process, optimizing the processing flow, and ensuring product quality.

[0054] Specifically, in order to achieve the lifting of the support plate 521, provide space for flipping, and avoid collision during flipping to cause damage to the circuit board, refer to Figure 8 The lifting assembly 53 includes two vertical rods 531 which are symmetrically distributed front and back and fixedly connected to the upper end of the support platform 51. The upper parts of the ends of the two vertical rods 531 close to each other are fixedly connected with a travel switch 2 56. The travel switch 2 56 is the same as the travel switch 1 54, and only the installation position is different. The inner surfaces of the two vertical rods 531 are slidably connected with a T-shaped slider 535. The upper ends of the two T-shaped sliders 535 are fixedly connected with cables 532. The ends of the two cables 532 away from the T-shaped slider 535 extend to the inner cavity of the support platform 51 and are fixedly connected with a winding disk 533. The two cables 532 are both wound around the outer surface of the winding disk 533 and their winding directions are opposite. The inner cavity of the support platform 51 is fixedly connected with a motor 1 534 fixedly connected to one end of the winding disk 533.

[0055] During operation, the motor 534 will drive the winding disk 533 to rotate, and tighten the vertical rod 531 so that it pulls the T-shaped slider 535 to slide upward in the vertical rod 531, thereby driving the support plate 521 to move upward. During the upward movement of the support plate 521, the clamping and flipping assembly 57 can lift the circuit board, and clamp the circuit board in cooperation with the clamping and flipping assembly 57, the T-shaped slider 535 and the vertical rod 531, thereby avoiding collision of the circuit board due to position offset or falling off during the flipping process, thereby reducing unnecessary property losses and ensuring product quality.

[0056] Furthermore, in order to clamp and fix the TV circuit board during the flipping process, refer to Figure 9 and Figure 10 , one end of the cross slider 5351 away from the T-shaped slider 535 is rotatably connected to the clamping and flipping assembly 57. Release grooves 536 are symmetrically opened on the lower part of the inner surface of the vertical part of the vertical rod 531 corresponding to the T-shaped slider 535. The clamping and flipping assembly 57 includes a mounting plate 571 rotatably connected to the cross slider 5351. Four limiting grooves 572 are rectangularly distributed at one end of the mounting plate 571 away from the cross slider 5351. Clamping arms 573 are slidably connected to the inner surfaces of the four limiting grooves 572. The clamping arms 573 are made of rubber, have certain buffering characteristics, and have high friction, which can reduce the sliding of the circuit board. Four hydraulic telescopic rods 574 are fixedly connected to the inner cavity of the mounting plate 571 in a rectangular distribution. The piston rods at the output ends of the four hydraulic telescopic rods 574 are respectively fixedly connected to the adjacent clamping arms 573.

[0057] Furthermore, in order to drive the flipping of the TV circuit board and drive the clamping arms 573 to act to clamp and fix the TV circuit board, refer to Figure 9 and Figure 10 , the clamping and flipping assembly 57 further includes a second motor 570 fixedly connected to the inner surface of the T-shaped slider 535. A driving shaft 576 is fixedly connected to the output end of the second motor 570. An oil storage cavity 578 is opened on the inner surface of the vertical part of the T-shaped slider 535. Wedge-shaped spring plates 579 communicating with the oil storage cavity 578 and adapted to the release grooves 536 are fixedly connected to both the left and right ends of the vertical part of the T-shaped slider 535. A driving shaft 576 fixedly connected to the mounting plate 571 is fixedly connected to the output end of the second motor 570. A communication hole 577 communicating with its inner cavity is opened on the part of the driving shaft 576 located on the inner surface of the oil storage cavity 578. A oil pipe 575 communicating with the four hydraulic telescopic rods 574 is rotatably connected to the inner cavity of the communication hole 577 through a slip ring.

[0058] The cross slider 5351 is fixed together with the clamping and flipping assembly 57 and will not move with the movement of the support plate 521. When the circuit board enters between the two support plates 521, it will slide into between the four clamping arms 573 and rest on the two lower clamping arms 573. When the support plate 521 rises, the four clamping arms 573 on both sides can lift the circuit board to rise synchronously with the support plate 521;

[0059] Further, when the T-shaped slider 535 rises, the wedge-shaped spring plates 579 on its left and right sides will disengage from the release groove 536 and be pressed into the oil storage chamber 578 by the inner wall of the vertical rod 531. At this time, the hydraulic oil inside the wedge-shaped spring plate 579 will enter the oil storage chamber 578, causing the hydraulic oil therein to enter the hydraulic telescopic rod 574 through the communication hole 577 and the oil pipe 575. The connection between the oil pipe 575 and the hydraulic telescopic rod 574 has a reverse effect, that is, when the hydraulic oil in the oil pipe 575 enters the hydraulic telescopic rod 574, the piston rod of the hydraulic telescopic rod 574 will retract, and then the hydraulic telescopic rod 574 is used to drive the clamping arm 573 to slide in the limit groove 572, thereby realizing the clamping and fixing of the circuit board.

[0060] Synchronously, when the T-shaped slider 535 reaches a predetermined height, at this time, the travel switch two 56 is triggered by the support plate 521, the motor one 534 stops, and the motor two 570 operates to drive the drive shaft 576 and the mounting plate 571 to rotate. Then, the circuit board is driven to flip through the mounting plate 571 and the clamping arm 573. After the flipping is completed, the motor one 534 reversely releases the cable 532, and under the action of gravity, the T-shaped slider 535 and the support plate 521 are reset, and the flipped circuit board is placed back above the support table 51.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention.
