Description

Technical Field

[0001] The utility model relates to a tube outer circular particle layer pasting technology, in particular to a regular mechanical arm of a tube outer circular particle layer pasting device. Background Art

[0002] In some equipment, it is necessary to paste a particle layer on the outer circle of the tube body, that is, to paste one or more particle layers on the outer circle surface of the equal-diameter circular tube body, the variable-diameter circular tube body or the conical tube body with quick-drying glue (such as 502 glue); the shape of the particles is a cube, a cuboid or a rhombus, etc. When pasting, the geometric axis of the particle pasting surface needs to be tangent to the surface of the tube body, and the bottom of each particle is required to be in close contact with the outer circle surface of the tube body and filled with quick-drying glue, the surrounding of the particle is in close contact with the adjacent particles and filled with quick-drying glue, and the gaps between the particles are staggered (see Appendix Figure 1 , in the figure, a is the tube body and b is the particle). Due to the processing error of the particle's external dimensions, the gaps between particles during pasting cannot be exactly the same. Therefore, the design specification specifically stipulates that the number of particles pasted in each circle shall not be less than the set number, and the gap between the last particle and the first particle shall not be greater than the width of one particle; and the number of particle circles in the axial direction of the tube body shall not be less than the set number, and the gap between the last circle of particles and the edge of the tube body shall not be greater than the length of one particle.

[0003] The existing process of pasting the outer circular particle layer of the pipe body adopts a manual method to paste. The particles are placed on the outer circular surface of the pipe body manually, and quick-drying glue is injected under the premise of stabilizing the position of the particles. After the glue is dry and sticky, the next particle pasting is carried out. Of course, one particle can be pasted at a time, or several particles can be pasted at a time; but the basic requirements are the same, that is, the bottom of each particle is in close contact with the outer circular surface of the pipe body and filled with quick-drying glue, and the surrounding of the particle is in close contact with the adjacent particles and filled with quick-drying glue. In addition, the number of particles in each circle and the number of axial circles must also meet the design requirements. In order to improve the pasting efficiency and quality, a device and method specifically used for pasting the outer circular particle layer of the pipe body have emerged. A mechanical transmission arm is used to transport the arranged particles to the surface of the pipe body, and then a regularizing manipulator is used to regularize the particles in three directions: circumference, radius and axial direction. The regularizing manipulator includes a reference baffle, a circumferential push plate, an axial push plate and a radial push plate; the reference baffle, circumferential push plate, axial push plate and radial push plate are all hydraulically driven. When the particles are arranged in a specific manner, for the initial pasting of each circle of particles, the reference baffle moves forward to block the rightmost particle at the set position, and the circumferential push plate moves from left to right to push the particles to be arranged neatly in the circumferential direction based on the reference baffle; for the pasting of the remaining particles in each circle of particles, the circumferential push plate moves from left to right to push the particles to be arranged neatly in the circumferential direction based on the already pasted particles; at the same time, the radial push plate moves toward the center of the tube body to push the particles to the outer circular surface of the tube body, so that the inner side of the particles is perpendicular to the outer circular surface of the tube body; the axial push plate moves downward along the axis of the tube body to push the particles to the edge step of the tube body or the previous circle of particles that have been pasted. In this way, the particles are neatly and orderly stacked in rows at the set position, and the set posture and position are kept unchanged (see attached Figure 2 and 3 , in the figure, a is the tube body, b is the particle, 1-1 is the reference baffle, 1-2 is the circumferential push plate, 1-3 is the radial push plate, and 1-4 is the axial push plate). At this time, the dispensing tube moves to the top of the particle and starts to inject quick-drying glue between the particle and the outer circular surface of the tube body and between the particles, thereby completing this round of particle pasting. Obviously, it is very important for the regularizing robot to regularize the particles in three directions: circumference, radius and axial direction. If the particles are not arranged neatly, or the posture of the particles is not right (that is, the inner side of the particle is not perpendicular to the outer circular surface of the tube body); it may cause the gap between the inner side of the particle and the outer circular surface of the tube body to be inconsistent, or the gap between the particles to be inconsistent, resulting in the pasting quality failing to meet the design requirements.

[0004] From the above analysis, it can be seen that the radial push plate of the regularizing robot of the prior art tube body outer circular particle layer pasting device is an overall arc shape. When the posture of individual particles in the whole row of particles is incorrect (for example, the inner side surface of individual particles is not normal to the outer circular surface of the tube body, but a certain edge of the particle is in contact with the outer circular surface of the tube body), the radial push plate may be "blocked" by the particle when pushing toward the center of the circle, which may cause problems in the arrangement or posture of the whole row of particles, resulting in the pasting quality of this round of particles failing to meet the design requirements.

[0005] Obviously, the conventional device for tidying up the outer circular particle layer of a tube body has the problem that the radial push plate may be "jammed", causing problems in the arrangement or posture of the entire row of particles, resulting in the particle pasting quality failing to meet the design requirements. Summary of the invention

[0006] In order to solve the problem that the radial push plate of the regularizing robot of the prior art device for pasting circular particle layers outside a tube body may be "jammed", causing problems in the arrangement or posture of the whole row of particles, resulting in the pasting quality of the particles failing to meet the design requirements, the utility model proposes a regularizing robot for the device for pasting circular particle layers outside a tube body.

[0007] The utility model discloses a tidying robot for the outer circular particle layer pasting device of the tube body, which adopts the tidying robot to tidy the particles in three directions: circumferential, radial and axial. The tidying robot comprises a reference baffle, a circumferential push plate, a radial push plate and an axial push plate. The characteristic of the tidying robot is that the radial push plate is a segmented structure, that is, the overall circular arc-shaped radial push plate is evenly divided into two or more sub-arc push plates from the circumferential direction, and each sub-arc push plate is provided with a hydraulic or starting drive. Moreover, each sub-arc push plate is combined to form the whole of the circular arc-shaped radial push plate.

[0008] Furthermore, a curved flexible pad is provided at the front end of each segment of the curved push plate.

[0009] Furthermore, the arc-shaped flexible pad is a silicone rubber flexible pad, a nitrile rubber flexible pad or a plastic flexible pad.

[0010] The beneficial technical effect of the regularizing manipulator of the outer circular particle layer pasting device of the utility model is that it can effectively avoid the phenomenon that the radial push plate may be "jammed", avoid the arrangement or posture problems of the whole row of particles, and effectively improve the pasting quality.

[0016] The following is a further description of the regularizing manipulator of the outer circular granular layer pasting device of the utility model in conjunction with the accompanying drawings and specific implementation methods. DETAILED DESCRIPTION

[0017] Attached Figure 4 The three-dimensional schematic diagram of the regular manipulator of the device for pasting the round granular layer outside the tube body of the utility model is shown in FIG. Figure 5 It is a three-dimensional schematic diagram of another embodiment of the regularizing manipulator of the device for pasting the outer circular particle layer of the tube body of the utility model; in the figure, a is the tube body, b is the particle, and 1-3-1 is the sub-arc push plate. As can be seen from the figure, the regularizing manipulator of the device for pasting the outer circular particle layer of the tube body of the utility model adopts the regularizing manipulator to regularize the particles from three directions: circumference, radius and axial direction. The regularizing manipulator includes a reference baffle, a circumferential push plate, a radial push plate and an axial push plate; it is characterized in that the radial push plate 1-3 is a segmented structure, that is, the overall arc-shaped radial push plate is evenly divided into two or more sub-arc push plates 1-3-1 from the circumferential direction, and each sub-arc push plate 1-3-1 is provided with a hydraulic or pneumatic drive; and each sub-arc push plate is combined to form the whole of the arc-shaped radial push plate. The regularizing manipulator of the device for pasting the outer circular particle layer of the tube body of the utility model adopts two or more sub-arc push plates, and each sub-arc push plate is provided with a hydraulic or pneumatic drive. When the posture of individual particles in a whole row of particles is incorrect, a certain section of the arc-shaped radial push plate may be affected by the particle, but it will not affect the advancement of other sub-arc-shaped push plates, so that most of the particles in the whole row can still be arranged as a whole and in the correct posture. In fact, since each section of the sub-arc-shaped push plate contacts fewer particles (usually no more than three particles), and the drive of this section of the sub-arc-shaped push plate is operated separately, with the push of this section of the sub-arc-shaped push plate, the particles with incorrect postures may be pushed by the sub-arc-shaped push plate and restored to the correct posture. It can be seen that the beneficial technical effect of the regular manipulator of the outer circular particle layer pasting device of the utility model is that it can effectively avoid the phenomenon that the radial push plate may be "blocked", avoid problems with the arrangement or posture of the whole row of particles, and effectively improve the pasting quality.

[0018] In order to further improve the ability of each segment of the arc-shaped push plate to push the particles or correct the posture of the particles, as one of the preferred solutions, the front end of each segment of the arc-shaped push plate is provided with an arc-shaped flexible pad. The addition of the flexible pad can prevent the pushing effect from being affected by the uneven surface of the particle when there is an error in the particle size within the tolerance range. In addition, when a certain edge of the particle contacts the outer circular surface of the tube body, so that the corresponding edge points to the front end of the sub-arc-shaped push plate, the flexible pad can play a better buffering role. Moreover, under the further push of the flexible pad, the particle may rotate and then return to the correct posture.

[0019] As one of the preferred solutions, the arc-shaped flexible pad is a silicone rubber flexible pad, a nitrile rubber flexible pad or a plastic flexible pad. The silicone rubber flexible pad, the nitrile rubber flexible pad or the plastic flexible pad can all be used as the flexible pad, and can be selected according to actual needs.

[0020] Obviously, the beneficial technical effect of the regular robot of the outer circular particle layer pasting device of the utility model is that it can effectively avoid the phenomenon that the radial push plate may be "blocked", avoid problems with the arrangement or posture of the whole row of particles, and effectively improve the pasting quality.
