Description

Technical Field

[0001] The utility model relates to a level ruler production device, in particular to a level ruler automatic leveling device. Background Art

[0002] A spirit level is a measuring instrument that uses the principle of liquid level to directly display angular displacement with a spirit bubble to measure the deviation of the measured surface relative to the horizontal position, plumb position, and tilt position. The spirit level consists of a spirit level body and a bubble located in the middle. The bubble needs to be fixed to the spirit level body during the production process. Therefore, whether the bubble can maintain the same parallelism with the spirit level body during the fixing process determines the quality of the spirit level itself. However, there are still a large number of manual operation links in the current spirit level production process. Although manual operations that are not easy to complete with some equipment can be completed manually, there are technical differences in manual operation, especially in the bubble installation link. If the bubble installation accuracy is not enough, the spirit levels produced will be defective products. Therefore, it is particularly important to develop a spirit level production equipment that can install bubbles with high precision. Summary of the invention

[0003] The utility model provides an automatic leveling device for a level ruler, which solves the problem in the prior art that it is difficult to ensure the installation accuracy of water bubbles on the manually installed level ruler.

[0004] The above technical problem of the utility model is mainly solved by the following technical solution: a level ruler automatic leveling device, characterized in that it comprises: a frame, a horizontal operating table is provided on the frame, a unilateral positioning part is fixed on the operating table, and the unilateral positioning part is generally a long straight strip structure;

[0005] A clamping assembly, which can press the level ruler body onto the unilateral positioning portion;

[0006] Two height adjustment components, including a vertically arranged servo linear guide rail module, a lifting seat and a push rod arranged on the lifting seat, wherein the two push rods are located above the two ends of the bubble;

[0007] A visual inspection system, comprising a light source module, a camera module and a display module, wherein the light source module and the camera module are arranged on both sides of the water bubble;

[0008] The glue injection component comprises a three-axis linear module and a glue injection head. The three-axis linear module can drive the glue injection head to move to the glue injection position of the bubble.

[0009] The operating principle of the utility model is: manual or automated equipment is used to send the already connected level ruler body and bubble to the middle of the operating table, and one side of the level ruler body is made to rest against the unilateral positioning part. At this time, the bubble is located on the upper surface of the level ruler body, and then the clamping assembly clamps the level ruler body on the unilateral positioning part, and the visual inspection system starts to perform visual inspection on the liquid bubble in the bubble, observes the actual position of the liquid bubble, and obtains the actual downward pressure distance of the two height adjustment assemblies through the algorithm, and then the two servo linear guide modules move accurately under the control of the controller, so that the two push rods are pressed against the two ends of the bubble, and ensure that the bubble and the level ruler body are parallel to each other, and then the glue injection assembly starts to dispense glue on the contact part between the bubble and the level ruler body, and the three-axis linear module can control the glue injection head to move accurately according to the preset trajectory, and finally the glue injection assembly, height adjustment assembly, and clamping assembly are reset, and the level ruler is removed by manual or automated equipment.

[0010] Furthermore, the lifting seat is also provided with a striking cylinder arranged downward, and the telescopic rod of the striking cylinder can strike the upper end of the push rod. After the bubble is combined with the level ruler body, the bubble may not be pressed down to a horizontal position due to some factors, such as stress, position deviation, burrs, etc. At this time, the striking cylinder can be started to quickly strike the push rod, so that the bubble can produce a slight jump, so that its position on the level ruler body is reset to eliminate the situation where it cannot be pressed down to the right position. This step may need to be repeated many times.

[0011] Furthermore, a mounting frame for mounting two height adjustment components is fixed on the operating table, and a horizontal guide rail and a reverse screw module are fixed on the mounting frame. Two horizontal slides are slidably matched on the horizontal guide rail, and two screw nuts are provided on the reverse screw module. The two screw nuts are respectively fixed on the two horizontal slides, and two servo linear guide rail modules are also respectively fixed on the two horizontal slides. By controlling the forward and reverse rotation of the reverse screw module, the two screw nuts will drive the two horizontal slides to move in the opposite direction along the horizontal guide rail, thereby realizing the control of the spacing between the two height adjustment components to adapt to the installation of different types of level rulers.

[0012] Furthermore, it also includes a level ruler positioning assembly, including a horizontally arranged linear moving module and a horizontal lever, wherein the distribution direction of the linear moving module is parallel to the length direction of the unilateral positioning portion. The level ruler positioning assembly is used to position the position of the level ruler in the length direction, and the specific positioning method is as follows: the level ruler loading position is deliberately biased toward one side of the level ruler positioning assembly, and before the clamping assembly is clamped, the linear moving module first drives the horizontal lever to move according to the set moving distance, and the horizontal lever can push the level ruler to move to the center position until the level ruler is unloaded, and the level ruler positioning assembly is reset.

[0013] Furthermore, two windows are correspondingly arranged on the operating table on both sides of the bubble, and the clamping assembly, the light source module and the glue injection assembly are all located in the windows and can be extended or retracted from the windows. When the clamping assembly, the light source module and the glue injection assembly are all retracted into the windows, there is no redundant structure on the operating table that will interfere with the loading and unloading of the level ruler.

[0014] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The visual detection system can perform visual detection on the liquid bubble in the bubble, and control the actual pressing distance of the two height adjustment components through an algorithm to ensure that the bubble and the level body are parallel to each other, and then the glue injection component starts to dispense glue on the contact part between the bubble and the level body, so that the utility model has a high-precision installation effect and a high degree of automation; 2. After the bubble is combined with the level body, the bubble may not be pressed down to a horizontal position due to some factors. At this time, the striking cylinder can be started to quickly knock the push rod, which can make the bubble jump slightly and reset its position on the level body to eliminate the situation where it cannot be pressed down into place.

[0025] See Figure 1 and Figure 5 , two sets of clamping assemblies 200, the clamping assemblies include a first linear module 210 vertically fixed on the frame, a first lifting platform 220, a first ejection module 230 arranged on the first lifting platform, and a pressing block 240, the first ejection module is a servo electric cylinder, and the pressing block is a flexible material with a certain elasticity;

[0026] See Figure 3 , two height adjustment components 300, including a vertically arranged servo linear guide rail module 310, a lifting seat 320 and a push rod 330 arranged on the lifting seat, the two push rods are located above the two ends of the bubble, and the lifting seat is also provided with a downwardly arranged striking cylinder 340, the telescopic rod of the striking cylinder can strike the upper end of the push rod (see Figure 7 );

[0027] See Figure 2 and Figure 5 , a visual inspection system, including a light source module 410, a camera module 420 and a screen display module 430, the light source module and the camera module are arranged on both sides of the bubble, and the light source module includes a second linear module 411 vertically fixed on the frame, a second lifting platform 412 and a light source 413;

[0028] See Figure 1 and Figure 6 The glue injection assembly 500 includes a three-axis linear module 510 and a glue injection head 520. The three-axis linear module can drive the glue injection head to move to the glue injection position of the bubble.

[0029] See Figure 3 and Figure 4The operating table is also fixed with a mounting frame 600 for mounting two height adjustment components, on which two parallel horizontal guide rails 610 and a reverse screw module 620 are fixed, and two horizontal slides 630 are slidably matched on the horizontal guide rails, and two screw nuts 640 are provided on the reverse screw module, and the two screw nuts are respectively fixed on the two horizontal slides, and two servo linear guide rail modules are also respectively fixed on the two horizontal slides. By controlling the forward and reverse rotation of the reverse screw module, the two screw nuts will drive the two horizontal slides to move in the opposite direction along the horizontal guide rails, thereby realizing the control of the spacing between the two height adjustment components to adapt to the installation of different types of level rulers.

[0030] See Figure 1 , also includes a level ruler positioning assembly 700, including a horizontally arranged linear moving module 710 and a horizontal lever 720, and the distribution direction of the linear moving module is parallel to the length direction of the unilateral positioning part.

[0031] See Figure 1 Two windows 130 are correspondingly arranged on the operating table on both sides of the bubble, and the clamping component, the light source module and the glue injection component are all located in the windows and can be extended or retracted from the windows.

[0032] The operating principle of this embodiment is as follows: in the initial state, the clamping assembly, the light source module and the glue injection assembly are all located in the window, and the operating table is almost unobstructed at this time, which makes it easy to load the level assembly using manual or automated equipment, and makes one side of the level body lean against the unilateral positioning portion, and the whole leans toward one side of the level positioning assembly. The linear moving module first drives the horizontal lever to move according to the set moving distance, and the horizontal lever can push the level to the center position, and then the clamping assembly starts the clamping action, and the first linear module pushes the first lifting platform to rise. At this time, the first ejection module extends out of the window and pushes the pressure block to clamp the level body on the unilateral positioning portion, and then the second linear module pushes the second lifting platform and The light source on it rises until it can fill in the light of the bubble. The camera module performs visual detection on the liquid bubble in the bubble, observes the actual position of the liquid bubble, and obtains the actual downward pressure distance of the two height adjustment components through the algorithm. Then the two servo linear guide modules move accurately under the control of the controller, so that the two push rods are on both ends of the bubble and ensure that the bubble and the level body are parallel to each other. Then the glue injection component starts to dispense glue on the contact part between the bubble and the level body. The three-axis linear module can control the precise movement of the glue injection head according to the preset trajectory. Finally, the light source module, glue injection component, height adjustment component, clamping component, and level positioning component are all reset, and the level is removed manually or with automated equipment.

[0033] After the bubble is combined with the spirit level body, the bubble may not be pressed down to a horizontal position due to some factors, such as stress, position deviation, burrs, etc. At this time, the striking cylinder can be started to quickly tap the push rod. This will cause the bubble to jump slightly and reset its position on the spirit level body to eliminate the situation where it cannot be pressed down into place. This step may need to be repeated many times.

[0034] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
