Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary components for automated equipment, specifically relating to an EL alignment wheel mounting plate. Background Technology

[0002] The EL alignment wheel mounting plate is a key auxiliary component of the EL testing production line. Its core function is to provide a stable mounting base for the alignment wheel body and guide the components to be accurately transferred on the production line, ensuring the accuracy and continuity of EL testing. In the actual application of EL testing in the front layer of Workshop 4, the alignment wheel was initially directly mounted on the profile. When producing large-size components, the installation position of the alignment wheel could not be adjusted outward, resulting in insufficient spacing between the alignment wheels on both sides of the production line, which directly affected normal production. To address this, the existing EL alignment wheel mounting plate has been equipped with an L-shaped bracket plate. The alignment wheel body is mounted on the L-shaped bracket plate through a fixing mechanism, and the L-shaped bracket plate is fixed to the profile through adjustable screw grooves and mounting screws. This not only allows for flexible adjustment of the alignment wheel spacing to accommodate large-size components, but also solves the previous problems of loosening caused by small spacing and inconvenient adjustment of the alignment wheel, as well as the fault of easy plate jamming during component transfer, ensuring stable operation of the equipment. However, during use, the alignment wheel lacks effective support and is susceptible to damage from lateral forces. When guiding component transmission, the alignment wheel is subjected to lateral forces due to component misalignment and transmission speed fluctuations. The existing mounting plate only fixes the wheel axle through a fixing mechanism and does not provide support for the edge of the alignment wheel body. The lateral forces are concentrated on the wheel axle for a long time, which can easily cause the wheel axle to tilt, bend, or even loosen the connection between the fixing mechanism and the wheel axle, affecting the guiding accuracy of the alignment wheel. In severe cases, it is necessary to stop the machine to replace the wheel axle, interrupting the production process. Moreover, the existing alignment wheel body has no additional support structure. During operation, it is prone to slight shaking due to its own weight or lateral forces, which makes it impossible for the alignment wheel to maintain a stable rotation trajectory. This shaking will cause the component to deviate from the preset path during transmission, which not only increases the risk of misjudgment in EL detection, but may also aggravate the friction between the component and the alignment wheel, causing scratches on the component surface or wear on the edge of the alignment wheel, increasing the product defect rate and component replacement costs. Utility Model Content

[0003] The purpose of this utility model is to provide an EL alignment wheel mounting plate to solve the problem mentioned in the background art that when the alignment wheel guide assembly is transmitted, due to component offset and speed fluctuation, it is subjected to lateral force. The existing mounting plate only relies on the fixing mechanism to fix the wheel axle and does not support the edge of the wheel axle. The lateral force concentration causes the wheel axle to tilt, bend or loosen, affecting accuracy. In severe cases, it is necessary to stop the machine and replace the wheel axle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an EL alignment wheel mounting plate, comprising an L-shaped bracket plate and adjustable screw grooves located on the left and right sides inside the center of the rear end of the L-shaped bracket plate.

The top of each of the four cuboid fixed bases is vertically provided with a metal support prism.

[0006] Preferably, the aligning wheel support and stabilizing device further includes a thickened metal shaft, a support and stabilizing roller, and a U-shaped wheel groove. The four metal support prisms are arranged at a circular angle around the outside of the wheel shaft. Each of the four metal support prisms has a U-shaped wheel groove inside its top, and the support and stabilizing roller is arranged inside the U-shaped wheel groove. The support and stabilizing roller is rotatably connected to the metal support prisms through the thickened metal shaft.

[0007] Preferably, the diameter of the supporting and stabilizing roller is greater than the depth of the U-shaped groove, the top of the metal supporting prism is semi-circular, and the upper half of the fan-shaped area of ​​the supporting and stabilizing roller is exposed outside the top of the metal supporting prism.

[0008] Preferably, the top of the supporting and stabilizing roller is in full contact with the bottom outer wall of the correcting wheel body near the edge, the center point between the four supporting and stabilizing rollers coincides with the rotation center of the correcting wheel body, and the rotation direction of the four supporting and stabilizing rollers revolves around a complete circle, that is, when the correcting wheel body rotates, it will drive the bottom supporting and stabilizing rollers to rotate synchronously through rolling friction.

[0009] Preferably, the fixing mechanism includes a left semi-circular fixing sleeve, a semi-circular anti-detachment ring, a fixed bearing, and a right semi-circular fixing sleeve. The left semi-circular fixing sleeve is provided on the outside of the left half of the fixed bearing, and the right semi-circular fixing sleeve is sleeved on the outside of the right half of the fixed bearing. The arc-shaped inner wall at the top of the left and right semi-circular fixing sleeves is provided with a semi-circular anti-detachment ring. The circular anti-detachment ring formed by the two semi-circular anti-detachment rings closing together blocks the top of the fixed bearing.

[0010] Preferably, the bottom end of the axle at the center of the correcting wheel body is inserted and fixed in the fixed bearing, and the axle can rotate clockwise and counterclockwise in the fixed bearing. The four cuboid fixed bases are arranged in a circular angle around the outer circular side of the left and right semicircular fixed sleeves after they are closed together, and the included angles between the four cuboid fixed bases and the center points of the front and rear ends and the left and right ends of the fixed bearing are all 45 degrees.

[0011] Preferably, the fixing mechanism further includes a left mounting fixing block, a right mounting fixing block, and fixing screws.

[0013] Compared with the prior art, this utility model provides an EL alignment wheel mounting plate, which has the following beneficial effects: This invention features four equidistant support and stabilizing devices added to the bottom of the alignment wheel body near its circular edge. These devices provide uniform and stable multi-point support to the alignment wheel body, effectively resisting lateral forces during operation. This prevents damage such as tilting and bending of the wheel axle due to uneven stress, significantly improving the operational stability and service life of the alignment wheel body. The four support and stabilizing devices are equidistantly distributed in a circular angle around the bottom edge of the alignment wheel body, forming a... The comprehensive support system ensures that when the aligning wheel is subjected to lateral force, the four support points can evenly distribute the force, avoiding wheel axle tilting caused by excessive force at a single point. This structurally improves the deformation resistance of the aligning wheel. Furthermore, the device's support and stabilizing rollers are rotatably connected to the metal support prism via a thickened metal shaft and maintain rolling contact with the bottom outer wall of the aligning wheel. This design allows the support and stabilizing rollers to rotate synchronously when the aligning wheel rotates, converting contact friction into rolling friction. While providing stable support, this minimizes the resistance to the rotation of the aligning wheel, ensuring its smooth operation. The device boasts strong structural adaptability and high support stability. The diameter of the supporting stabilizing roller is greater than the depth of the U-shaped groove, ensuring full contact with the centering wheel body. The semi-circular treatment at the top of the metal support prism and the concentric arrangement of the four support points with the center of rotation of the centering wheel further guarantee the accuracy and stability of the support, ensuring that the support force always acts in the correct direction. This effectively counteracts the adverse effects of lateral forces on the wheel axle. By resisting lateral forces and preventing the wheel axle from tilting or bending, the device significantly reduces the risk of wear and damage to the centering wheel body and wheel axle, decreasing the frequency of maintenance and replacement due to component deformation, and indirectly improving the overall operational reliability and economy of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-5 The diagram shows an EL alignment wheel mounting plate. This EL alignment wheel mounting plate's core design goals are stable installation, precise alignment, and long-term support. Through a scientifically arranged layout and connection method, the various components achieve stable fixation and smooth operation of the alignment wheel body 6. The spacing adjustment capability is optimized, especially for the production needs of large-size components. The core supporting component of the mounting plate is the L-shaped bracket plate 1. The core value of this design lies in solving the production pain point of insufficient alignment wheel spacing on the front EL production line of workshop 4. Previously, the alignment wheels were directly installed on the profiles. When making large-size components, the installation position of the alignment wheels could not be adjusted outwards, resulting in excessively small spacing. This not only made adjustment inconvenient and caused the alignment wheels to loosen easily, but also frequently led to component jamming problems, affecting normal production. The L-shaped bracket... The upper half of plate 1 extends forward horizontally, serving as the mounting carrier for the alignment wheel body 6 and the fixing mechanism 5. Two adjustable screw grooves 2 are vertically formed on the left and right sides of the rear center, with mounting screws 3 inserted into them. The L-shaped bracket plate 1 is fixed to the profile via the mounting screws 3. The adjustment principle of this structure is that the height of the bracket plate can be finely adjusted up and down via the adjustable screw grooves 2. More importantly, the horizontal extension design of the L-shaped bracket plate 1, combined with the flexibility of profile installation, allows for outward expansion of the alignment wheel's installation position, thereby freely adjusting the spacing between the alignment wheels on both sides of the production line. This perfectly accommodates the production of large-size components. Simultaneously, locking the mounting screws 3 prevents the alignment wheel from loosening, fundamentally solving the component jamming problem and ensuring normal equipment operation.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fixing mechanism 5 is installed at the top middle section of the L-shaped bracket plate 1. It is the core component connecting the centering wheel body 6 and the bracket plate. Through a semi-circular splicing and anti-detachment limiting design, it achieves precise fixing and free rotation of the wheel axle. The core rotating component of the fixing mechanism 5 is the fixed bearing 13. The bottom end of the wheel axle at the center of the centering wheel body 6 is inserted and fixed in the bearing. The wheel axle can rotate freely clockwise and counterclockwise in the bearing, providing a smooth rotational basis for the centering action of the centering wheel body 6. The fixed bearing 13 adopts a left-right splicing fixing structure. The left half is fitted with a left semi-circular fixing sleeve 11, and the right half is fitted with a right semi-circular fixing sleeve 14. After the two semi-circular fixing sleeves are closed, they form a complete circular sleeve that completely encloses the fixed bearing 13. This splicing design facilitates later disassembly and maintenance (such as replacing the bearing) without the need to completely dismantle the mechanism, improving the convenience of operation and maintenance. The top arc-shaped inner wall of the left semi-circular fixing sleeve 11 and the right semi-circular fixing sleeve 14 are both equipped with semi-circular anti-detachment retaining rings 1. 2. After the two retaining rings close, they form a complete circular anti-disengagement retaining ring, which is precisely blocked at the top of the fixed bearing 13. This structure can limit the upward displacement of the wheel shaft and prevent the centering wheel body 6 from being dislodged from the bearing due to vibration or lateral force, thus ensuring operational safety. The lower half of the left semicircular fixed sleeve 11 has a left mounting fixing block 10 at the left end, and the lower half of the right semicircular fixed sleeve 14 has a right mounting fixing block 15 at the right end. Both are fixed to the top of the L-shaped bracket plate 1 by fixing screws 16, locking the position of the fixed sleeve from the bottom. At the same time, the arc-shaped outer walls at both ends of the left semicircular fixed sleeve 11 have left metal connecting blocks 9, and the corresponding positions of the right semicircular fixed sleeve 14 have right metal connecting blocks 8. The connecting blocks are connected by fastening screws 7. When the fastening screws 7 are tightened, the left and right connecting blocks will move closer to each other, further reducing the gap between the two semicircular fixed sleeves, ensuring that the fixed sleeve and the fixed bearing 13 fit tightly, preventing the bearing from shaking. Combined with the stable installation of the L-shaped bracket plate 1, this provides double protection to prevent the centering wheel from loosening.

[0023] like Figure 1 , Figure 4 and Figure 5As shown, to address the issue of the axle tilting and bending easily caused by lateral forces during operation of the aligning wheel body 6, four aligning wheel support and stabilizing devices 4 are equidistantly arranged at the bottom near the circular edge of the aligning wheel body 6. Through multi-point uniform support and rolling friction coordination, the aligning wheel's lateral resistance and smooth operation are enhanced. The bottom of each of the four support and stabilizing devices is a cuboid fixed base 17, which is fixed to the top of the L-shaped bracket plate 1 by multiple base screws 19, ensuring that the entire device remains stationary. The cuboid fixed bases 17 are equidistantly distributed in a circular angle, surrounding the closed left semicircular fixed sleeve 11 and right semicircular fixed sleeve 1. 4. The outer side, and the angle between the center point of the front and rear, left and right ends of the fixed bearing 13 and the center point of the fixed bearing 13 are all 45°. This layout can make the four support points form an all-round symmetrical support system, ensuring that the force can be evenly distributed when the correcting wheel body 6 is subjected to force, avoiding single-point overload. Each cube fixed base 17 has a metal support prism 18 vertically set at the top. The top of the prism is semi-circular, which not only avoids sharp edges from scratching the correcting wheel body 6, but also reduces contact friction with the correcting wheel. At the same time, the four metal support prisms 18 are distributed around the outer side of the wheel axle to ensure that the support force always acts on the reasonable position of the edge of the correcting wheel and accurately resists the lateral force.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, a U-shaped groove 22 is formed inside the top of the metal support prism 18, and a support and stabilizing roller 21 is installed in the groove. The roller is rotatably connected to the prism via a thickened metal shaft 20. The thickened metal shaft 20 can improve the rotational stability of the roller and prevent the roller from deforming due to force. The diameter of the support and stabilizing roller 21 is larger than the depth of the U-shaped groove 22, so that the upper half of the fan-shaped area of ​​the roller is exposed outside the top of the prism, and it is in full contact with the bottom outer wall of the correcting wheel body 6 near the edge, forming a tight rolling support. The key design principle is that the center point of the four support and stabilizing rollers 21 is aligned with the rotation of the correcting wheel body 6. With the centers of rotation coinciding and the rollers rotating around a complete circle, when the alignment wheel body 6 rotates, it will drive the supporting and stabilizing roller 21 to rotate synchronously through rolling friction, converting sliding friction into rolling friction. While providing stable support, it minimizes the resistance to the rotation of the alignment wheel, ensuring smooth alignment. At the same time, continuous rolling contact can resist the lateral force on the alignment wheel in real time, preventing the wheel axle from tilting or bending due to uneven force, significantly extending the service life of the alignment wheel and wheel axle. Combined with the L-shaped bracket plate 1 to solve the spacing and clamping plate problems, it fully ensures the stability of large-size component production.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
