Description

Technical Field

[0001] This utility model relates to the field of sheet metal technology, and in particular to a sheet metal side perpendicularity monitoring device. Background Technology

[0002] During the production of cleanroom panels, the perpendicularity of the panels, especially the perpendicularity of the side surface (i.e., the side surface) to the two panels, is required to be high. When the perpendicularity of the side surface of the panel is poor, it will cause gaps in the walls or ceiling of the cleanroom, which will not only affect the aesthetics, but also cause the cleanroom environment to fail to meet the standards.

[0003] In related technical solutions, dial indicators or micrometers are used to measure the perpendicularity of the board side at multiple points. The perpendicularity of the board side is calculated by measuring the dial indicator readings. However, this type of testing equipment is time-consuming and labor-intensive, making it inconvenient to monitor the perpendicularity of the board side in real time during the production process. This can easily lead to the failure to detect products with substandard perpendicularity, resulting in the outflow of substandard products. Utility Model Content

[0004] This invention provides a device for monitoring the verticality of the side of a sheet metal, which can at least solve one of the above-mentioned technical problems.

[0005] To address the aforementioned technical problems, one or more embodiments of this utility model provide a plate side perpendicularity monitoring device, which has a horizontal and perpendicular first direction and a second direction. It includes a base plate with a horizontal upper surface. A slide table capable of sliding along the first direction is provided on the base plate. A column is fixed on the slide table, and a slide block capable of vertically rising and falling is provided on the column. At least one measuring head capable of extending and falling along the second direction is mounted on the slide block. A spring is installed between the measuring head and the slide block, configured to provide a spring force to the measuring head extending out of the slide block. A capacitive displacement sensor is installed between the measuring head and the slide block, and the capacitive displacement sensor is signal-connected to a PLC controller. Frames are respectively installed at both ends of the base plate along the first direction. A cantilever is fixed to the upper end of the frame, and a pressure roller mechanism is mounted on the cantilever. The pressure roller mechanism can vertically rise and fall to press the plate to be measured on the base plate.

[0006] The beneficial effects of one or more of the above technical solutions are as follows:

[0007] In this design, the upper surface of the base plate is horizontal, which facilitates the use of the base plate to provide partial support for the boards in the production line. A pressure roller assembly is installed above the base plate, which helps to press the board to be tested against the base plate from top to bottom, ensuring that the board's surface is also horizontal. In other words, this design facilitates the use of the base plate and pressure roller assembly to provide partial support for the board being measured as it is conveyed along the production line, thereby facilitating the monitoring of the board's side perpendicularity during the production process.

[0008] In this design, the base plate is equipped with a slide table that moves in a first direction, a column that moves vertically, and a measuring head that extends and retracts in a second direction. This allows the slide table to drive the measuring head to move in the first direction, ensuring that the measuring head moves at the same speed as the material being measured. Combined with the vertical movement of the slide table, the displacement difference between two points on the side surface of the material and the reference point marked by the measuring head can be measured, thereby calculating the perpendicularity of the side surface of the material.

[0014] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0015] Example 1

[0016] like Figures 1-3As shown, one or more embodiments of this utility model provide a plate side perpendicularity monitoring device, which has a horizontal and perpendicular first direction and a second direction. It includes a base plate 1 with a horizontal upper surface. A slide table 13 capable of sliding along the first direction is provided on the base plate 1. A column 6 is fixed on the slide table 13. A slide seat 10 capable of vertically rising and falling is provided on the column 6. At least one measuring head 14 capable of extending and falling along the second direction is installed on the slide seat 10. A spring 146 is installed between the measuring head 14 and the slide seat 10, and the spring 146 is configured to provide a spring force to the measuring head 14 to extend out of the slide seat 10. A capacitive displacement sensor is installed between the measuring head 14 and the slide seat 10, and the capacitive displacement sensor is connected to a PLC controller. Frames 9 are respectively installed at both ends of the base plate 1 along the first direction. A cantilever 8 is fixed to the upper end of the frame 9, and a pressure roller mechanism 2 is installed on the cantilever 8. The pressure roller mechanism 2 can vertically rise and fall to press the plate to be measured on the base plate 1.

[0017] Specifically, in this embodiment, the base plate 1 is a square plate with a square horizontal surface on its upper surface to horizontally support the lower panel of the plate to be tested. Correspondingly, the slide table 13 is a square platform, and the lower end surface of the slide table 13 is in contact with the upper surface of the base plate 1.

[0018] Specifically, the horizontal cross-section of the aforementioned column 6 can be square or circular, which can be determined by those skilled in the art. Furthermore, the central axis of the column 6 is vertically aligned, and the outer surface of the column 6 is also vertically arranged.

[0019] Specifically, the elastic force of the spring 146 causes the measuring head 14 to extend out of the slide 10 and abut against the side of the plate to be measured. The side of the plate provides a reaction force to the measuring head 14, which causes the measuring head 14 to retract into the slide 10. The capacitive sensor here includes two electrode plates, one of which is fixedly attached to the measuring head 14 and the other of which is fixedly attached to the slide 10. The displacement between the measuring head 14 and the slide 10 is monitored by the capacitive sensor, thereby monitoring the extent to which the measuring head 14 extends out of the slide 10.

[0020] Specifically, the pressure roller mechanism 2 includes a frame 3, on which multiple pressure rollers are arranged in a row along a first direction. A vertically arranged electric push rod 5 or hydraulic cylinder, etc., is fixed above the frame. One end of the electric push rod, etc., is fixed to the frame, and the other end is fixed to the upper cantilever 8. Furthermore, the axis of each pressure roller is parallel to a second direction. A vertical guide rod 4 is also arranged between the frame 3 and the cantilever 8.

[0021] In this embodiment, the base plate 1 is provided with a first slide groove 11 along the first direction, and the bottom of the slide table 13 has a first slider 12 embedded in the first slide groove 11; the column 6 is provided with a second slide groove 16 along the vertical direction, and the side wall of the slide seat 10 has a second slider embedded in the second slide groove 16.

[0022] Specifically, the first slide groove 11 penetrates the upper surface of the base plate 1, and the second slide groove 16 penetrates the outer side of the column 6, so that the slide table 13 is slidably connected to the base plate 1 through the first slide groove 11, and the slide block 10 is slidably connected to the column 6 through the second slide groove 16.

[0023] In this embodiment, the first slide groove 11 and the second slide groove 16 are T-shaped grooves or dovetail grooves.

[0024] Correspondingly, the first slider 12 is a T-shaped block or a dovetail block, and the second slider is also a T-shaped slider or a dovetail block. In this embodiment, it is sufficient that the corresponding groove and the shape of the matching slider are compatible. In other embodiments, the first groove 11 and the second groove 16 can also adopt other shapes, which can be set by those skilled in the art.

[0025] In this embodiment, the measuring head 14 includes a column 142 and a cone 141 disposed at the end of the column 142, with the cone head of the cone 141 facing outward from the slide block 10; the column 142 has a shoulder 1421 in the middle, and a spring 146 is sleeved on the outside of the column 142, with one end of the spring 146 abutting against the shoulder 1421; the slide block 10 is provided with a stepped hole, which includes a first hole 143 and a second hole 144, with the diameter of the first hole 143 being larger than the diameter of the second hole 144, the first hole 143 penetrating through the outer wall of the slide block 10, and the other end of the spring 146 abutting against the inner wall of the second hole 144.

[0026] Specifically, the stepped hole here is a blind hole. The diameter of the first hole 143 is equal to the diameter of the cylinder 142, the diameter of the second hole 144 is greater than the diameter of the cylinder 142 and the shoulder 1421, and the diameter of the spring 146 is equal to the diameter of the cylinder 142. During use, the end of the cylinder 142 extending into the stepped hole always maintains a gap with the bottom wall of the stepped hole perpendicular to its own axial direction to prevent the bottom wall of the stepped hole from hindering the extension and retraction of the cylinder 142 along its own axial direction.

[0027] In this embodiment, a linear drive assembly 17 is provided on the base plate 1 to drive the slide table 13 to slide along a first direction. Specifically, the linear drive assembly is a hydraulic cylinder, a linear motor, a lead screw and nut assembly, or a linear motor.

[0028] Furthermore, the linear drive assembly is arranged horizontally, with one end fixed to the slide table 13 and the other end fixed to the base plate 1.

[0029] In this embodiment, the column 6 is equipped with a lifting drive assembly 7 to drive the slide 10 to rise and fall. Specifically, the lifting drive assembly 7 adopts a hydraulic cylinder, a linear motor, a lead screw and nut assembly, or a linear motor.

[0030] Furthermore, the lifting drive assembly 7 is arranged vertically here, with one end of the lifting drive assembly 7 fixed to the column 6 and the other end fixed to the slide block 10.

[0031] Working principle: When using this device, the entire monitoring device is arranged on one side of the board production line, so that the first direction of the monitoring device is parallel to the conveying direction of the board production line.

[0032] A monitoring section is installed at the output end of the board production line, with the width of the conveyor line being smaller than the width of the board. This causes a portion of the board structure to protrude from the production line and be supported by the base plate 1. Correspondingly, a retaining edge should be installed on one side of the board production line along the width direction to limit the board's movement in a second direction.

[0033] When the side of the board moves to the point where it begins to pass the measuring head 14, the measuring head 14 extends outward and abuts against the side surface of the board. At this time, the linear drive assembly drives the measuring head 14 to move at the same speed as the board along the first direction. The lifting drive assembly 7 drives the measuring head 14 to rise and fall, so that the measuring head 14 measures multiple points at that position.

[0034] By measuring the readings at different heights of the measuring head 14, the inclination angle of the side of the plate conveyor line relative to the vertical plane is calculated, and thus the verticality of the side is obtained.

[0035] Example 2

[0036] like Figure 4 As shown, the structure of this embodiment is basically the same as that of embodiment 1, and it also provides a plate side perpendicularity monitoring device. The difference is that in this embodiment, the slide table 13 and the column 6 are located in the middle of the base plate 1 along the second direction, and the column 6 forms a measurement space 15 on both sides along the second direction. Each measurement space 15 is equipped with a pair of uprights 9 and a pressure roller mechanism 2. The slide 10 includes a lifting part 1001 and a rotating part 1002. The lifting part 1001 is connected to the column 6, and the rotating part 1002 can rotate relative to the lifting part 1001 around the rotating shaft 1003 parallel to the first direction, so that the measuring head 14 on the rotating part 1002 can be switched to face the two measurement spaces 15 respectively.

[0037] In this embodiment, the lifting part 1001 is provided with horizontal stop plates 1004 at both ends along the second direction to stop the rotating part 1002.

[0038] The slide 10 is configured with a lifting part 1001 that can be raised and lowered and a rotating part 1002 that can be rotated, so that the individual measuring head 14 can face the measuring space 15 in different directions respectively, thereby enabling the monitoring device to intermittently monitor the side perpendicularity of the plates on two different production lines along the second direction through the individual measuring head 14.

[0039] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0040] Any aspects of this utility model not described in detail are known to those skilled in the art.
