Description

Technical Field

[0001] The present invention relates to the technical field of displays, in particular to automatic assembly equipment for a screen and a frame of a terminal display. Background Art

[0002] The cash register POS display is a device used to display transaction information. It is usually installed at the cash register or merchant counter. It can display detailed information such as product name, price, quantity and total price, and can record each transaction data. The cash register POS display also has many practical functions, such as storing and backing up transaction data, which is convenient for future inquiries; it can also support multiple payment methods, providing consumers with more flexible payment options.

[0003] The existing assembly of the screen and frame of the POS display is generally performed by manually taking the screen and installing it on the frame.

In addition, due to the fragility of the screen, the screen may be damaged, increasing costs and reducing work efficiency. Therefore, an automatic assembly device for the screen and frame of a terminal display is proposed to solve the problems raised by the background technology. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, the present invention provides an automatic assembly device for the screen and frame of a terminal display, including a placement table 1, a motor 2 is movably connected to one side of the placement table 1, a bidirectional threaded rod 3 is fixedly connected to the output shaft end of the motor 2, a gear 4 is fixedly connected to the middle of the bidirectional threaded rod 3, sliders 5 are threadedly connected to both ends of the bidirectional threaded rod 3, a first clamping plate 6 is movably connected inside the slider 5, a cavity 7 is provided in the inner cavity of the first clamping plate 6, a first piston rod 8, a second piston rod 9 and a connecting rod assembly 10 are movably connected inside the first clamping plate 6, a second clamping plate 12 and a third clamping plate 13 are movably connected inside the placement table 1, guide grooves 14 located on both sides of the first clamping plate 6 are provided on the inner wall of the placement table 1, a spring 15 is fixedly connected inside the cavity 7, and a frame body 16 is placed on the top of the placement table 1.

[0033] The above scheme is adopted: the motor 2 is operated to drive the bidirectional threaded rod 3 to rotate, thereby driving the sliders 5 and the first clamping plate 6 at both ends thereof to move toward each other. While the first clamping plate 6 moves, the convex rods at both ends thereof slide along the trajectory of the guide groove 14 and move the first clamping plate 6 upward, thereby moving the top of the first clamping plate 6 to the outside of the placement table 1. While the bidirectional threaded rod 3 rotates, it drives the gear 4 in the middle to rotate. At this time, the gear 4 engages with the second clamping plate 12 and the third clamping plate 13 to move the two toward each other. Subsequently, the second clamping plate 12 and the third clamping plate 13 respectively abut against the outer walls on both sides of the frame body 16, and the two first clamping plates 6 respectively abut against the outer walls on the other two sides of the frame body 16, thereby clamping the frame body 16, thereby fixing the position of the frame body 16.

[0034] like Figures 1 to 6 As shown, the connecting rod assembly 10 includes a first connecting rod 1001 fixedly connected to the top of the second piston rod 9, a second connecting rod 1002 is hingedly connected to one end of the first connecting rod 1001 away from the second piston rod 9, a third connecting rod 1003 is hingedly connected to the middle of the second connecting rod 1002, a fourth connecting rod 1004 is hingedly connected to the other end of the third connecting rod 1003, the bottom of the third connecting rod 1003 is fixedly connected to the top of the first clamping plate 6, a fifth connecting rod 1005 is hingedly connected to one end of the second connecting rod 1002 away from the first connecting rod 1001, and the second connecting rod 1003 is hingedly connected to the top of the first clamping plate 6. 002 rotates with the top of the third connecting rod 1003 as the axis, and a straight slot is provided at one end of the second connecting rod 1002 close to the first connecting rod 1001, which is used for the top of the first connecting rod 1001 to slide in the straight slot when it rises. The middle part of the fifth connecting rod 1005 is hinged to one end of the fourth connecting rod 1004, and the bottom end of the fifth connecting rod 1005 is fixedly connected with an inclined block 11. The first clamping plate 6 is initially located inside the placing table 1, and convex rods are provided on both sides of the first clamping plate 6, and the convex rods move inside the guide groove 14.

[0035] The above scheme is adopted: the two first clamping plates 6 move toward each other and drive the first piston rod 8 on one side thereof to move in the same direction, and then the two first piston rods 8 abut against the two sides of the frame body 16, and the first clamping plates 6 continue to move toward each other. At this time, the two first piston rods 8 are squeezed by the frame body 16 and move in opposite directions, so that the gas in the cavity 7 is compressed and pushes the second piston rod 9 upward. When the second piston rod 9 moves upward, it drives the first connecting rod 1001 upward and pushes the second connecting rod 1002 to rotate with one end of the third connecting rod 1003 as the axis, and then the second connecting rod 1002 drives the fifth connecting rod 1005 and the inclined block 11 at the other end to move downward, so that the inclined block 11 abuts against the inner wall of the frame body 16, thereby reducing the deviation caused by the suction cup when placing the screen. The first clamping plate 6 is initially located inside the placement table 1 to facilitate the placement of the frame body 16.

[0036] like Figures 1 to 6As shown, when the two-way threaded rod 3 rotates, it drives the two first clamping plates 6 to move toward each other. When the two first clamping plates 6 move toward each other, the convex rod drives the first clamping plate 6 to move upward along the trajectory of the guide groove 14. The first piston rod 8 penetrates the outer wall of the first clamping plate 6 and extends to the outside thereof. The spring 15 is used to support the first piston rod 8. When the two first clamping plates 6 move toward each other, the first piston rod 8 is driven to abut against the frame body 16. The first piston rod 8 and the second piston rod 9 are respectively movable inside the cavity 7. When the two first piston rods 8 move in opposite directions, the gas in the cavity 7 is compressed and the second piston rod 9 is pushed upward. When the second piston rod 9 moves upward, it rotates through the second connecting rod 1002 and drives the fifth connecting rod 1002. The rod 1005 drives the inclined block 11 to move downward, and there is a gap between the two inclined blocks 11 and the inner wall of the frame body 16. The second clamping plate 12 and the third clamping plate 13 are respectively provided with teeth at the bottom. When the gear 4 rotates, the second clamping plate 12 and the third clamping plate 13 are moved toward each other through the teeth at the bottom. The second clamping plate 12 and the third clamping plate 13 pass through the top of the placement table 1 and extend to the outside thereof. After the second clamping plate 12 and the third clamping plate 13 move toward each other, they abut against the frame body 16. The inner wall of the placement table 1 is respectively provided with sliding grooves 17 located on both sides of the second clamping plate 12 and the third clamping plate 13. The sliding grooves 17 are used to limit the second clamping plate 12 and the third clamping plate 13 when they move toward each other.

[0037] The above scheme is adopted: a gap is left between the inclined block 11 and the inner wall of the frame body 16 to avoid the situation where the first clamping plate 6 cannot be reset when it moves in the opposite direction. The first piston rod 8 is supported by the spring 15, so that when the two first clamping plates 6 move in the opposite direction, the two first piston rods 8 are driven to move toward each other by the elastic force of the spring 15, thereby moving the second piston rod 9 downward and driving the inclined block 11 to reset.

[0038] The working principle and usage process of the present invention are as follows: the motor 2 is operated to drive the bidirectional threaded rod 3 to rotate. The rotation of the bidirectional threaded rod 3 drives the sliders 5 and the first clamping plate 6 at both ends to move toward each other. While the first clamping plate 6 moves, the convex rods at both ends slide along the trajectory of the guide groove 14, thereby driving the first clamping plate 6 to move upward, so that the top of the first clamping plate 6 moves to the outside of the placement table 1. At the same time, the rotation of the bidirectional threaded rod 3 drives the gear 4 in the middle to rotate. At this time, the gear 4 engages with the second clamping plate 12 and the third clamping plate 13, thereby causing the two to move toward each other. Subsequently, the second clamping plate 12 and the third clamping plate 13 respectively abut against the two sides of the frame body 16, and the two first clamping plates 6 respectively abut against the other two sides of the frame body 16, thereby clamping the frame body 16 to complete the operation.

[0039] When the two sliders 5 move toward each other, the first clamping plate 6 moves upward inside the slider 5 through the guide groove 14, so that the top of the first clamping plate 6 moves to the outside of the placement table 1. When the two first clamping plates 6 move toward each other, they drive the first piston rod 8 on one side to move in the same direction. Then, the two first piston rods 8 abut against the two sides of the frame body 16. At this time, the first clamping plates 6 continue to move toward each other, so that the two first piston rods 8 are squeezed by the frame body 16 and move in the opposite direction. When the first piston rod 8 moves, The gas in the cavity 7 is compressed and pushes the second piston rod 9 inside it upward. The second piston rod 9 moves upward and drives the first connecting rod 1001 upward at the same time. Then, the top of the first connecting rod 1001 slides in the straight groove of the second connecting rod 1002 and drives the second connecting rod 1002 to rotate around the top of the third connecting rod 1003. Then, the second connecting rod 1002 drives the fifth connecting rod 1005 at the other end to move downward, and drives the inclined block 11 to move downward, so that the inclined block 11 is located inside the frame body 16, and the operation is completed.
