Description

Technical Field

[0001] The present invention belongs to the technical field of instrument housing assembly, and specifically relates to a robot for assembling instrument housings. Background Art

[0002] With the rapid development of electronic technology, the demand for various instruments is increasing. An electric meter is an instrument used to measure electric energy. When manufacturing an electric meter, it is necessary to install the main board of the electric meter in a plastic shell to protect the internal main board and facilitate use.

[0003] A patent application with the publication number CN111376031B discloses an assembly device for an instrument housing. The heights of the positioning tooling and the clamping member are both greater than or equal to the sum of the height of the pressing plate and the height of the instrument housing, so that the positioning tooling and the clamping member can accommodate the instrument housing and the pressing plate at the same time. There is no need to equip a special upper mold to carry the upper shell. The overall structural principle is simple and easy to implement. Through the joint positioning of the positioning tooling and the clamping member, this non-closed structure is adopted, and it is more convenient to place the lower shell of the instrument and take out the instrument housing after assembly. At the same time, a rodless cylinder and a guide rail are used, making the picking and placing faster, improving the assembly efficiency, and reducing the loss caused by improper force.

[0004] In the above-mentioned prior art, when assembling an electric meter, it is necessary to install the main board of the electric meter in a plastic shell. The plastic shell is usually divided into an upper shell and a lower shell. First, place the main board of the electric meter in the lower shell, and then install the upper shell at the upper end of the lower shell. The size of the main board of the electric meter is the same as that of the plastic shell. Since the surface of the main board is uneven, it is impossible to pick up the main board of the electric meter using a suction cup. The prior art generally uses a clamping plate to clamp both sides of the main board of the electric meter. When clamping and placing the main board of the electric meter in the lower shell, since the gap between the main board of the electric meter and the lower shell is small, the clamping plate cannot enter the lower shell. After the clamping device clamps the main board of the electric meter to the upper end of the lower shell, there is still a certain distance between the main board of the electric meter and the lower shell at this time. At this time, it is necessary to stop clamping the main board of the electric meter and let the main board of the electric meter slide into the lower shell. The main board of the electric meter falls freely into the lower shell, resulting in low installation accuracy and possible damage to the main board of the electric meter.

[0005] Therefore, the present invention provides a robot for assembling instrument housings. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Embodiment 1: As Figures 1-6 shown, a meter housing assembly robot according to an embodiment of the present invention includes a first disc 1 rotatably provided at the upper end of a bottom plate 8. First clamping components are respectively provided around the upper end of the first disc 1. The first clamping component includes a bevel block 12 slidably provided at the upper end of the first disc 1. First L-shaped clamping plates 121 are respectively slidably provided on both sides of the upper end of the bevel block 12. The first clamping component is used for clamping the lower meter housing. Assembly robotic arms 2 are respectively provided on both sides of the first disc 1. Second clamping components are respectively provided at the output ends of the assembly robotic arms 2. The second clamping component includes a first rectangular plate 21 rotatably provided at the output end of the assembly robotic arm 2. Second L-shaped clamping plates 22 are respectively slidably provided on both sides of the lower end of the first rectangular plate 21. One side of the assembly robotic arm 2 is used for assembling the meter main board, and a display screen is installed on the upper end of the meter main board. The other side of the assembly robotic arm 2 is used for assembling the upper meter housing.

[0024] Specifically, when assembling the electricity meter, the main board of the electricity meter needs to be installed inside the electricity meter housing. The electricity meter housing is usually divided into an upper housing and a lower housing of the electricity meter. First, place the main board of the electricity meter in the lower housing of the electricity meter, and then install the upper housing of the electricity meter at the upper end of the lower housing of the electricity meter. The size of the main board of the electricity meter is the same as that of the electricity meter housing. Since the surface of the main board is uneven, it is impossible to pick up the main board of the electricity meter using a suction cup. The prior art generally uses a clamping plate to clamp both sides of the main board of the electricity meter. When clamping and placing the main board of the electricity meter in the lower housing of the electricity meter, since the gap between the main board of the electricity meter and the lower housing of the electricity meter is small, the clamping plate cannot enter the lower housing of the electricity meter. After the clamping plate clamps the main board of the electricity meter to the upper end of the lower housing of the electricity meter, there is still a certain distance between the main board of the electricity meter and the lower housing of the electricity meter at this time. At this time, it is necessary to stop clamping the main board of the electricity meter and let the main board of the electricity meter slide into the lower housing of the electricity meter. The main board of the electricity meter falls freely into the lower housing of the electricity meter, resulting in a low installation accuracy and possible damage to the main board of the electricity meter. When using this assembly robot, place the lower housing of the electricity meter on the upper end of the bevel block 12, then drive the first L-shaped clamping plate 121 to clamp the lower housing of the electricity meter, and then drive the first disc 1 to rotate to drive the lower housing of the electricity meter to rotate to one side of the assembly robotic arm 2. Then drive the assembly robotic arm 2 on one side to move. The assembly robotic arm 2 drives the second L-shaped clamping plate 22 to clamp the display screen fixedly connected to the upper end of the main board of the electricity meter. Then drive the assembly robotic arm 2 to drive the main board of the electricity meter to move to the upper end of the lower housing of the electricity meter, and then slowly place the main board of the electricity meter into the lower housing of the electricity meter until the main board of the electricity meter is completely placed in the lower housing of the electricity meter. Then drive the first disc 1 to rotate to drive the lower housing of the electricity meter with the main board of the electricity meter installed to rotate to the side of another assembly robotic arm 2. Then drive the assembly robotic arm 2 to move. The assembly robotic arm 2 drives the second L-shaped clamping plate 22 to clamp the upper housing of the electricity meter. Then drive the assembly robotic arm 2 to drive the upper housing of the electricity meter to move to the upper end of the lower housing of the electricity meter until the upper housing of the electricity meter is installed at the upper end of the lower housing of the electricity meter. By driving the assembly robotic arm 2 to drive the second L-shaped clamping plate 22 to clamp the display screen of the electricity meter, the main board of the electricity meter can be slowly placed into the lower housing of the electricity meter until the main board of the electricity meter is completely placed in the lower housing of the electricity meter, solving the problem that the gap between the main board of the electricity meter and the lower housing of the electricity meter is small, the second L-shaped clamping plate 22 cannot enter the lower housing of the electricity meter, and after clamping the main board of the electricity meter to the upper end of the lower housing of the electricity meter, it is necessary to let the main board of the electricity meter fall freely into the lower housing, resulting in low installation accuracy and possible damage to the main board of the electricity meter.

[0025] Such as Figures 1-2As shown in the figure, first rectangular grooves 11 are respectively formed around the first disc 1, and bevel blocks 12 are respectively slidably arranged in the first rectangular grooves 11. Feeding assemblies are respectively arranged around the first disc 1. The feeding assembly includes a first conveyor belt 4 installed at the upper end of a bottom plate 8, and the first conveyor belt 4 is used for conveying the lower shell of the electric meter. The feeding assembly further includes a second conveyor belt 5 installed at the upper end of the bottom plate 8, and the second conveyor belt 5 is used for conveying the main board of the electric meter. One of the assembling robotic arms 2 is arranged on one side of the second conveyor belt 5. The feeding assembly further includes a third conveyor belt 6 installed at the upper end of the bottom plate 8, and the third conveyor belt 6 is used for conveying the upper shell of the electric meter. The other assembling robotic arm 2 is arranged on one side of the third conveyor belt 6.

[0026] Specifically, by starting the first conveyor belt 4, the lower shell of the electric meter placed on the upper end can be driven to automatically move to one side of the first disc 1, which is convenient for the picking of the assembling robotic arm 2. By starting the second conveyor belt 5, the main board of the electric meter placed on the upper end can be driven to automatically move to one side of the first disc 1, which is convenient for the picking of the assembling robotic arm 2. By starting the third conveyor belt 6, the upper shell of the electric meter on the upper end can be driven to automatically move to one side of the first disc 1, which is convenient for the picking of the assembling robotic arm 2. By driving the rotation of the first disc 1 and cooperating with the assembling robotic arm 2, the assembly can be completed.

[0027] As Figure 2 shown in the figure, the lower end of the first disc 1 is fixedly connected to a second disc 131 through a cylindrical block 13. First electric slide rails 132 are respectively fixedly connected to the upper end of the second disc 131 corresponding to the positions of the bevel blocks 12. The bevel blocks 12 are respectively slidably arranged on the upper ends of the first electric slide rails 132. The output end of a motor 14 is fixedly connected to the lower end of the second disc 131. The motor 14 is installed on the upper end of the bottom plate 8 through a motor base.

[0028] Specifically, by starting the motor 14, the second disc 131 can be driven to rotate. The second disc 131 drives the first disc 1 to rotate through the cylindrical block 13. By driving the bevel blocks 12 to slide on the upper ends of the first electric slide rails 132, the bevel blocks 12 can be driven to slide to the upper end of the first conveyor belt 4, so that the lower shell of the electric meter on the upper end of the first conveyor belt 4 slides along the bevel of the bevel block 12 to the upper end of the bevel block 12. The whole assembling robot has a small floor area and high practicability.

[0029] As Figure 3 、 Figure 7 shown in the figure, second rectangular grooves 1211 are respectively formed at the lower ends of the first L-shaped clamping plates 121. Rectangular blocks 122 are respectively fixedly connected to the upper ends of the bevel blocks 12 corresponding to the positions of the second rectangular grooves 1211. The first L-shaped clamping plates 121 are slidably arranged outside the rectangular blocks 122 through the second rectangular grooves 1211. The rectangular blocks 122 are fixedly connected to one side inside the second rectangular grooves 1211 through first springs 123. A second rectangular plate 41 is slidably arranged on the upper end of the first conveyor belt 4.

[0030] Specifically, when driving the hypotenuse block 12 to slide to the upper end of the first electric slide rail 132 and reach the upper end of the first conveyor belt 4, simultaneously drive the second rectangular plate 41 to slide downward, so that the second rectangular plate 41 abuts against one side of the lower housing of the electricity meter. One side of the hypotenuse block 12 slides downward along the hypotenuse to the lower end of the lower housing of the electricity meter, so that the lower housing of the electricity meter slides between the two first L-shaped clamping plates 121. At the same time, the first L-shaped clamping plates 121 slide outside the rectangular block 122 through the second rectangular groove 1211 and compress the first spring 123 until the lower housing of the electricity meter completely slides to the upper end of the hypotenuse block 12. At the same time, the two first L-shaped clamping plates 121 clamp the lower housing of the electricity meter. Subsequently, drive the hypotenuse block 12 to slide away from one side of the first conveyor belt 4. Subsequently, drive the first disc 1 to rotate, driving the lower housing of the electricity meter at the upper end of the hypotenuse block 12 to rotate to one side of the assembly robot arm 2, and then subsequent assembly can be carried out.

[0031] As Figure 7 shown, the output ends of the first hydraulic rods 42 are fixedly connected to both sides of the second rectangular plate 41, and the first hydraulic rods 42 are fixedly connected to the upper end of the bottom plate 8.

[0032] Specifically, by driving the first hydraulic rod 42 to contract, drive the second rectangular plate 41 to move downward, so that the second rectangular plate 41 is located on one side of the lower housing of the electricity meter. Subsequently, the hypotenuse block 12 can be driven to slide to the upper end of the first conveyor belt 4. One side of the hypotenuse block 12 slides downward along the hypotenuse to the lower end of the lower housing of the electricity meter until the lower housing of the electricity meter completely slides to the upper end of the hypotenuse block 12.

[0033] As Figure 3 shown, a number of rotating wheels 1212 are respectively rotatably arranged on the opposite sides of the first L-shaped clamping plates 121.

[0034] Specifically, when driving one side of the hypotenuse block 12 to slide downward along the hypotenuse to the lower end of the lower housing of the electricity meter, so that the lower housing of the electricity meter slides between the two first L-shaped clamping plates 121, the lower housing of the electricity meter contacts the rotating wheels 1212. When the lower housing of the electricity meter slides between the two first L-shaped clamping plates 121, it drives the rotating wheels 1212 to rotate, preventing friction against the lower housing of the electricity meter.

[0035] As Figure 6 shown, the second clamping assembly further includes air bags 221 fixedly connected to the opposite sides of the second L-shaped clamping plates 22 respectively, and the air bags 221 are fixedly connected through a telescopic plate 223.

[0036] Specifically, since the surface of the display screen installed at the upper end of the main board of the electricity meter is relatively fragile, scratches may be caused during clamping. By providing air bags 221 on the opposite sides of the second L-shaped clamping plates 22, when driving the two second L-shaped clamping plates 22 to slide towards the middle simultaneously at the lower end of the first rectangular plate 21 to clamp the display screen, the air inside the telescopic plate 223 is squeezed, so that the air inside the telescopic plate 223 enters the air bag 221, making the air bag 221 in an inflated state. Subsequently, the air bag 221 contacts the display screen to clamp the display screen, and the air bag 221 contacts the surface of the display screen to prevent scratches from being caused.

[0037] Embodiment 2: As Figures 8-9 shown, compared with Embodiment 1, another implementation manner of the present invention is: a material taking assembly is provided on one side of the first disc 1. The material taking assembly includes a fourth conveyor belt 7 installed at the upper end of a bottom plate 8. A rectangular support table 71 is provided on one side of the fourth conveyor belt 7. The rectangular support table 71 is fixedly connected to the upper end of the bottom plate 8. The rectangular support table 71 is arranged on one side of the first disc 1. A third rectangular plate 72 is longitudinally slidably arranged at the upper end of the rectangular support table 71. Second rectangular strips 73 are fixedly connected to both sides of the lower end of the third rectangular plate 72. A fourth rectangular plate 75 is horizontally slidably arranged at the upper end of the rectangular support table 71.

[0038] Specifically, after the assembly is completed, drive the first disc 1 to drive the assembled electricity meter to rotate to one side of the rectangular support table 71. Subsequently, drive the bevel block 12 to drive the assembled electricity meter to slide to the upper end of the rectangular support table 71. Then drive the third rectangular plate 72 to drive the second rectangular strips 73 to move downward, so that the second rectangular strips 73 move to both sides of the assembled electricity meter. Then drive the bevel block 12 to slide away from the rectangular support table 71. The assembled electricity meter remains on the upper end of the rectangular support table 71. Then drive the fourth rectangular plate 75 to slide towards the fourth conveyor belt 7 to push the electricity meter assembled on the upper end of the rectangular support table 71 onto the upper end of the fourth conveyor belt 7, and convey the assembled electricity meter to the next processing step to complete automatic blanking, which is convenient for continuous processing.

[0039] As Figure 9 shown, first rectangular strips 721 are arranged on both sides of the lower end of the third rectangular plate 72. Cylindrical strips 722 are fixedly connected to the upper ends of the first rectangular strips 721 respectively. The cylindrical strips 722 slidably penetrate through the third rectangular plate 72. A second spring 723 is sleeved on the outer side of the upper end of the cylindrical strip 722. The upper end of the cylindrical strip 722 is fixedly connected to the upper end of the third rectangular plate 72 through the second spring 723. The output ends of second hydraulic rods 74 are fixedly connected to the four corners of the third rectangular plate 72 respectively. The second hydraulic rods 74 are fixedly connected to the four corners of the rectangular support table 71 respectively.

[0040] Specifically, by driving the second hydraulic rod 74 to contract, the second hydraulic rod 74 drives the third rectangular plate 72 to move downward. The third rectangular plate 72 drives the first rectangular strip 721 to move downward through the cylindrical bar 722. The first rectangular strip 721 contacts the upper housing of the electricity meter and presses the upper housing of the electricity meter downward. At the same time, it drives the cylindrical bar 722 to slide in the middle of the third rectangular plate 72 and squeeze the second spring 723 to prevent excessive squeezing of the upper housing of the electricity meter, making the installation of the upper housing and the lower housing of the electricity meter more firm.

[0041] As Figure 9 shown, on the side away from the fourth conveyor belt 7 of the fourth rectangular plate 75, a T-shaped block 752 is fixedly connected through a cylindrical rod 751. One side of the T-shaped block 752 is fixedly connected to the output end of a third hydraulic rod 753, and the third hydraulic rod 753 is fixedly connected to the lower end of the rectangular support table 71.

[0042] Specifically, by driving the third hydraulic rod 753 to contract, the third hydraulic rod 753 drives the fourth rectangular plate 75 to move toward the side close to the fourth conveyor belt 7 through the T-shaped block 752 and the cylindrical rod 751, pushing the assembled electricity meter on the upper end of the rectangular support table 71 to the upper end of the fourth conveyor belt 7, transporting the assembled electricity meter to the next processing step, completing automatic blanking, and facilitating continuous processing.

[0043] Working principle: When driving the bevel block 12 to slide on the upper end of the first electric slide rail 132 to the upper end of the first conveyor belt 4, at the same time, driving the second rectangular plate 41 to slide downward, so that the second rectangular plate 41 abuts against one side of the lower housing of the electricity meter. One side of the bevel block 12 slides downward along the bevel to the lower end of the lower housing of the electricity meter, making the lower housing of the electricity meter slide between the two first L-shaped clamping plates 121. At the same time, the first L-shaped clamping plates 121 slide outside the rectangular block 122 through the second rectangular groove 1211 and squeeze the first spring 123. When the lower housing of the electricity meter slides between the two first L-shaped clamping plates 121, the lower housing of the electricity meter contacts the rotating wheel 1212. When the lower housing of the electricity meter slides between the two first L-shaped clamping plates 121, it drives the rotating wheel 1212 to rotate, preventing friction against the lower housing of the electricity meter; Subsequently, starting the motor 14 can drive the second disc 131 to rotate. The second disc 131 drives the first disc 1 to rotate through the cylindrical block 13. By driving the inclined edge block 12 to slide on the upper end of the first electric slide rail 132, the inclined edge block 12 can be driven to slide to the upper end of the second conveyor belt 5. Subsequently, drive the assembly robotic arm 2 to move. The assembly robotic arm 2 drives the second L-shaped clamping plate 22 to clamp the display screen fixedly connected to the upper end of the main meter board. By providing an airbag 221 on the opposite side of the second L-shaped clamping plate 22, when driving the two second L-shaped clamping plates 22 to slide towards the middle simultaneously under the lower end of the first rectangular plate 21 to clamp the display screen, the air inside the telescopic plate 223 is squeezed, causing the air inside the telescopic plate 223 to enter the airbag 221, making the airbag 221 in an inflated state. Subsequently, the airbag 221 contacts the display screen to clamp the display screen. The airbag 221 contacts the surface of the display screen to prevent scratches. Subsequently, drive the assembly robotic arm 2 to drive the main meter board to move to the upper end of the lower meter housing. Subsequently, slowly place the main meter board into the lower meter housing until the main meter board is completely placed inside the lower meter housing. Subsequently, drive the first disc 1 to rotate, driving the lower meter housing with the main meter board installed to rotate to one side of another assembly robotic arm 2. Subsequently, drive the assembly robotic arm 2 to move. The assembly robotic arm 2 drives the second L-shaped clamping plate 22 to clamp the upper meter housing.
