Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for panel manufacturing, in particular to a speed reducer shaft gear transmission mechanism and a panel handling device including the same. Background Technique

[0002] During the manufacturing process of the panel of a display device, a panel handling device is often used. This panel handling device is used to move the panel to a corresponding station for corresponding operations. Among the components of the panel handling device, a transmission structure for driving a handling manipulator to carry the panel is a relatively important part.

[0003] In traditional equipment, as shown in Figure 1 , a transmission gear 1' is connected to the output shaft of a speed reducer and drives a transmission belt to move to achieve transmission of an external device. However, for the stability of the transmission of the transmission gear 1', an installation groove 11' for a support structure is provided on the side of the transmission gear 1' away from the speed reducer, and the support stability of the transmission gear 1' is achieved through the support structure. Generally, an installation groove 11' for installing a bearing 2' is provided on the transmission gear 1'. By installing the bearing 2' in the installation groove 11', and then connecting an external support structure through the inner ring 22' of the bearing 2', the support of the transmission gear 1' is achieved, and the bearing 2' does not interfere with the transmission of the transmission gear 1'.

[0004] However, in actual operation, since the hardness of the outer ring 21' of the bearing 2' is greater than that of the transmission gear 1', during the transmission operation of the equipment, the outer ring 21' generates friction on the inner wall of the installation groove 11' inside the transmission gear 1' and wears the inner wall of the installation groove 11'. The gap between the transmission gear 1' and the outer ring 21' increases, resulting in the bearing 2' losing the support force for the transmission gear 1'. Thus, under the pulling of the conveyor belt on the transmission gear 1', the coaxiality between the transmission gear 1' and the speed reducer is offset, affecting the transmission efficiency. Moreover, it will also cause uneven stress on the internal gears of the speed reducer and wear, affecting the normal operation of the speed reducer, reducing the service life of the speed reducer, increasing production costs. Summary of the Utility Model

[0005] One object of the utility model is to provide a speed reducer shaft gear transmission mechanism, which can effectively ensure the support strength and support stability of the transmission gear, ensure the coaxiality of the transmission gear and the speed reducer, thereby reducing the damage of the speed reducer and improving the service life of the speed reducer.

The transmission gear is located between the mounting bracket and the support bracket. A bearing is provided on the support bracket. The outer ring of the bearing is connected to the support bracket. An installation groove is recessed on one side surface of the transmission gear close to the support bracket. The speed reducer shaft gear transmission mechanism further includes a connection support member. One end of the connection support member is inserted into the installation groove and fixedly connected to the transmission gear. The other end of the connection support member is fixedly connected to the inner ring of the bearing.

[0009] In one embodiment, the connection support member includes a connection bottom plate and a support shaft that are connected to each other. The connection bottom plate is inserted into the installation groove. The support shaft passes through the connection through hole of the inner ring of the bearing and is fixedly connected to the inner ring of the bearing.

[0010] In one embodiment, the connection support member further includes a limit shaft. The limit shaft is disposed between the connection bottom plate and the support shaft. The size of the limit shaft is larger than the size of the connection through hole.

[0011] In one embodiment, it further includes a mounting bracket. The mounting bracket includes a connection plate and a mounting plate that are connected to each other. A first support hole is provided on the connection plate. The output shaft housing of the speed reducer passes through and is mounted on the first support hole. The support bracket is fixedly mounted on the mounting plate.

[0012] In one embodiment, the connection plate and the mounting plate are disposed at an angle. A reinforcing rib member is provided at the connection between the connection plate and the mounting plate.

[0013] The reinforcing rib member includes a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is respectively connected to the plate surfaces of the connection plate and the mounting plate. The second reinforcing rib is connected to the other plate surface of the connection plate and one side surface of the mounting plate.

[0014] In one embodiment, the support bracket further includes a support plate and a support seat. The support plate is fixedly connected to the support seat. A second support hole for installing the bearing is provided on the support plate. The support seat is fixedly connected to the mounting plate.

[0015] In one embodiment, it further includes a protective sleeve. The protective sleeve is disposed between the inner wall of the installation groove and the connection support member.

[0016] In one embodiment, a plurality of first mounting holes are provided in the mounting groove, and a plurality of second mounting holes corresponding to the first mounting holes are provided on the connection support member.

[0018] On the other hand, a panel handling device is provided, which includes a base and a handling manipulator, and also includes the above-mentioned speed reducer shaft gear transmission mechanism. The speed reducer shaft gear transmission mechanism is arranged on the base and is in transmission connection with the handling manipulator to drive the handling manipulator to reciprocate on the base.

[0019] Advantages of the present utility model:

[0020] For the speed reducer shaft gear transmission mechanism of the present utility model, one side of the connection support member is inserted into the mounting groove recessed in the transmission gear and fixedly connected to the transmission gear to realize the supporting effect of the connection support member on the transmission gear. Moreover, due to the fixed connection between the connection support member and the transmission gear, during the rotation transmission of the transmission gear driven by the driving motor and the speed reducer, the connection support member is fixed and rotates synchronously with the transmission gear, thereby reducing the possibility of relative movement between the two, effectively avoiding the wear of the mounting groove by the connection support member, ensuring the stability of the transmission of the transmission gear, and further avoiding the situation of damage to the internal components of the speed reducer caused by the deviation of the coaxiality between the transmission gear and the speed reducer, which is beneficial to improving the transmission stability, transmission efficiency and service life of the speed reducer.

[0021] Furthermore, the side of the connection support member away from the transmission gear is rotatably connected to the support frame through a bearing and is mounted on the support frame. Since the transmission gear will drive the connection support member to rotate synchronously during the rotation transmission, the design of the support frame and the bearing can not only support the connection support member to a certain extent, but also avoid interfering with the rotational movement of the connection support member following the transmission gear, which is beneficial to avoiding affecting the transmission efficiency of the speed reducer and the transmission gear and ensuring the transmission stability of the overall equipment.

[0022] The utility model provides a panel handling device, comprising a base and a handling robot, wherein the handling robot is slidably arranged on the base, and is connected to the handling robot through the above-mentioned reducer shaft gear transmission mechanism, so as to drive the handling robot to reciprocate on the base. Thus, the reciprocating handling operation of the panel is realized by the handling robot. Moreover, through the drive and transmission of the above-mentioned reducer shaft gear transmission mechanism, the handling robot can maintain good stability in the movement on the base, so that the handling robot can achieve stability in handling the panel, and can effectively avoid the problem of vibration causing damage to the panel or even causing the panel to fall.

[0037] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0038] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense.

[0040] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] As Figures 1 to 9 shown, a speed reducer shaft gear transmission mechanism of this embodiment includes a driving motor 61, a speed reducer 62, a transmission gear 1, a mounting bracket 5 and a support bracket 4. The driving motor 61 is arranged on one side surface of the mounting bracket 5. The output shaft end of the driving motor 61 is connected to the speed reducer 62. The speed reducer 62 is in transmission connection with the transmission gear 1. The support bracket 4 is arranged on the side surface of the mounting bracket 5 away from the driving motor 61. The transmission gear 1 is located between the mounting bracket 5 and the support bracket 4. A bearing 2 is arranged on the support bracket 4. The outer ring 21 of the bearing 2 is connected to the support bracket 4. An installation groove 11 is recessed on one side surface of the transmission gear 1 close to the support bracket 4. The speed reducer shaft gear transmission mechanism further includes a connection support member 3. One end of the connection support member 3 is inserted into the installation groove 11 and fixedly connected to the transmission gear 1. The other end of the connection support member 3 is fixedly connected to the inner ring 22 of the bearing 2.

[0042] In this embodiment, one side of the connection support member 3 is inserted into the installation groove 11 recessed in the transmission gear 1 and fixedly connected to the transmission gear 1 to realize the supporting effect of the connection support member 3 on the transmission gear 1. Moreover, due to the fixed connection between the connection support member 3 and the transmission gear 1, during the process of the transmission gear 1 rotating and transmitting driven by the driving motor 61 and the speed reducer 62, the connection support member 3 is fixed and rotates synchronously with the transmission gear 1, thereby reducing the possibility of relative movement between the two, effectively avoiding the wear of the connection support member 3 on the installation groove 11, ensuring the transmission stability of the transmission gear 1, and further avoiding the situation that the internal components of the speed reducer 62 are damaged due to the deviation of the coaxiality between the transmission gear 1 and the speed reducer 62, which is beneficial to improving the transmission stability, transmission efficiency and service life of the speed reducer 62.

[0043] Furthermore, the side of the connection support member 3 away from the transmission gear 1 is rotationally connected to the bearing 2 and erected on the support bracket 4. Since the transmission gear 1 will drive the connection support member 3 to rotate synchronously during the rotation and transmission process, the design of the support bracket 4 and the bearing 2 can not only support the connection support member 3 to a certain extent, but also avoid interfering with the rotational movement of the connection support member 3 following the transmission gear 1, which is beneficial to avoiding affecting the transmission efficiency of the speed reducer 62 and the transmission gear 1 and ensuring the transmission stability of the overall device.

[0044] In actual operation, the connecting support member 3 is not a standard part like the bearing 2. Therefore, the connecting support member 3 can be made of a material with a hardness similar to that of the transmission gear 1, which is convenient for material selection and production. In actual situations, due to vibrations or handling of the equipment, collisions and frictions still occur between the connecting support member 3 and the transmission gear 1. However, the connecting support member 3 and the transmission gear 1 with similar materials can cause as little wear as possible, thus ensuring the supporting force of the connecting support member 3 on the transmission gear 1 and facilitating the normal transmission of the overall device.

[0045] Furthermore, the support frame 4 can be made of a material with a hardness similar to that of the outer ring 21 of the bearing 2. Thus, during the transmission process, the support frame 4 and the outer ring 21 of the bearing 2 with similar materials can cause as little wear as possible, ensuring the supporting force between the support frame 4 and the bearing 2, that is, ensuring the supporting force of the bearing 2 on the connecting support member 3 and the transmission gear 1, which is conducive to ensuring the normal transmission of the overall device.

[0046] In one embodiment, the connecting support member 3 includes a connecting bottom plate 31 and a support shaft 33 connected to each other. The connecting bottom plate 31 is inserted into the installation groove 11, and the support shaft 33 passes through the connection through hole 23 of the inner ring 22 of the bearing 2 and is fixedly connected to the inner ring 22 of the bearing 2, thereby realizing the rotational connection of the connecting support member 3 to the support frame 4 through the bearing 2.

[0047] In one embodiment, a number of first installation holes 111 are provided in the installation groove 11, and a number of second installation holes 311 corresponding to the first installation holes 111 are provided on the connecting support member 3. The transmission gear 1 and the connecting support member 3 are fixedly connected by fasteners passing through the first installation holes 111 and the second installation holes 311 respectively.

[0048] Specifically, the bottom of the installation groove 11 is circular, and a number of first installation holes 111 are evenly distributed around the central axis of the bottom of the groove, so that the connection and installation of the connecting bottom plate 31 and the transmission gear 1 are stable, and the fasteners such as bolts placed in each of the first installation holes 111 and the second installation holes 311 are evenly stressed. Further, the central axes of the first installation holes 111 and the second installation holes 311 are parallel to the rotation center axis of the transmission gear 1, so that during the transmission of the transmission gear 1, the shearing force on the fasteners passing through the first installation holes 111 and the second installation holes 311 has the least impact on the fasteners, which is conducive to reducing the damage to the fasteners caused by the rotational shearing force, improving the overall stability, and also conducive to increasing the service life of the fasteners.

[0049] In one embodiment, the connecting support member 3 further includes a limiting shaft 32. The limiting shaft 32 is arranged between the connecting base plate 31 and the support shaft 33, and the size of the limiting shaft 32 is larger than that of the connecting through hole 23. The driving gear 1 and the bearing 2 are spaced apart by the limiting shaft 32. Due to the limiting effect of the limiting shaft 32 on the bearing 2, during the transmission process, the bearing 2 is prevented from sliding along the connecting shaft towards the driving gear 1 side and colliding or rubbing against the driving gear 1, thereby effectively protecting the driving gear 1 and improving the transmission stability and service life of the overall device.

[0050] In one embodiment, the reducer shaft gear transmission mechanism further includes a mounting bracket 5. One side of the mounting bracket 5 is connected to the reducer 62, and the other side of the mounting bracket 5 is connected to the support frame 4. Specifically, the mounting bracket 5 includes a connecting plate 51 and a mounting plate 52 that are connected to each other. The connecting plate 51 is provided with a first support hole 511, and the output shaft housing 621 of the reducer 62 passes through and is mounted on the first support hole 511. The support frame 4 is fixedly installed on the mounting plate 52. Thus, the support frame 4 is connected to the output shaft housing 621 through the mounting bracket 5, which is beneficial to maintaining the stability of the overall device. Among them, as Figure 7 shown, the mounting plate 52 is provided with first fixing holes 521 for fixedly connecting the mounting plate 52 to an external platform or external device, maintaining the connection and fixation of the overall device to the external platform or external device, which is beneficial to ensuring the transmission stability of the overall device.

[0051] In one embodiment, the connecting plate 51 and the mounting plate 52 are arranged at an angle, and a reinforcing rib member 53 is provided at the connection between the connecting plate 51 and the mounting plate 52. The connection strength between the support plate 41 and the mounting plate 52 is improved through the reinforcing rib member 53, thereby improving the overall structural stability of the mounting bracket 5.

[0052] Specifically, as Figure 7 shown, the reinforcing rib member 53 includes a first reinforcing rib 531 and a second reinforcing rib 532. The first reinforcing rib 531 is respectively connected to the plate surfaces of the connecting plate 51 and the mounting plate 52, and the second reinforcing rib 532 is connected to the other plate surface of the connecting plate 51 and one side surface of the mounting plate 52. That is, by respectively arranging the first reinforcing rib 531 and the second reinforcing rib 532 on both sides of the connecting plate 51, it is not only beneficial to improve the connection strength between the connecting plate 51 and the mounting plate 52 to improve the overall structural strength of the mounting bracket 5, but also can effectively improve the support strength and support stability of the connecting plate 51 itself, enabling the connecting plate 51 to provide strong support for the reducer 62 and further improving the transmission stability of the overall device. Further, the bottom surface of the second reinforcing rib 532 is flush with the bottom surface of the mounting plate 52. Thus, through the cooperation of the second reinforcing rib 532 and the mounting plate 52, the flatness of the overall mounting bracket 5 on the horizontal plane can also be improved, thereby further improving the overall stability of the mounting bracket 5.

[0053] In one embodiment, the support frame 4 further includes a support plate 41 and a support base 42. The support plate 41 is fixedly connected to the support base 42 to improve the stability of the support plate 41. A second support hole 411 for installing the bearing 2 is provided on the support plate 41. The bearing 2 is in transitional fit or clearance fit with the second support hole 411, and the second support hole 411 is used to fix and support the bearing 2. Among them, the support base 42 is fixedly connected to the mounting plate 52. A second fixing hole 522 for fixedly connecting the support base 42 is provided on the mounting plate 52. In actual operation, the support base 42 and the mounting plate 52 are fixedly connected by fasteners such as bolts.

[0054] In one embodiment, a protective sleeve 12 is further included. The protective sleeve 12 is arranged between the inner wall of the mounting groove 11 and the connecting and supporting member 3 to avoid friction between the connecting and supporting member 3 and the inner wall of the mounting groove 11. In actual application, the speed reducer shaft gear transmission mechanism of this embodiment is applied to the field of manufacturing the panel 9 of a display device, belonging to the high-precision technology field. During the rotation and transmission of the transmission gear 1, although the transmission gear 1 is fixedly connected to the connecting and supporting member 3, there may still be a certain amount of frictional collision at the fixed connection between the two. Or due to equipment vibration or handling, etc., collisions and frictions may still occur between the connecting and supporting member 3 and the transmission gear 1.

[0055] In the above situation, even if friction occurs between the two and debris is generated, in the panel 9 manufacturing operation with extremely high precision requirements, even very small or even invisible debris to the naked eye may affect the processing quality of the panel 9 if it falls on the panel 9. Therefore, through the protective sleeve 12 in this embodiment, the transmission gear 1 and the connecting and supporting member 3 can be effectively protected, and the friction between the transmission gear 1 and the connecting and supporting member 3 can be avoided.

[0056] In actual operation, the protective sleeve 12 is made of a heat-resistant soft protective sleeve, so that the protective sleeve 12 can withstand the high temperature generated during the transmission of the transmission gear 1, and the soft protective sleeve 12 can play a good protective and buffering role for the transmission gear 1 and the connecting and supporting member 3.

[0057] Particularly, a plurality of avoidance holes 121 corresponding to the first mounting holes 111 are provided on the side surface of the protective sleeve 12 opposite to the mounting groove 11 to prevent interference with the fixed connection between the transmission gear 1 and the connecting and supporting member 3 and ensure the smooth connection between the transmission gear 1 and the connecting and supporting member 3.

[0058] Such as Figure 10As shown in the figure, this embodiment also provides a panel handling device, which includes a base 8 and a handling manipulator 81. The handling manipulator 81 is slidably arranged on the base 8. This panel handling device also includes the speed reducer shaft gear transmission mechanism of the above embodiment. The speed reducer shaft gear transmission mechanism is arranged on the base 8 and is in transmission connection with the handling manipulator 81 to drive the handling manipulator 81 to reciprocate on the base 8. Thus, the reciprocating handling operation of the panel 9 is realized through the handling manipulator 81.

[0059] Moreover, through the drive and transmission of the above speed reducer shaft gear transmission mechanism, the movement of the handling manipulator 81 on the base 8 can maintain good stability, so that the handling manipulator 81 can achieve the stability of handling the panel 9, effectively avoiding the problems of damage to the panel 9 caused by vibration or even dropping of the panel 9.

[0060] Specifically, the handling manipulator 81 includes a sliding seat 811 and a handling support 812. A slide rail 82 for the sliding seat 811 to slide is provided on the base 8. At the same time, the sliding seat 811 is fixedly connected to the conveyor belt 7. The conveyor belt 7 is driven to reciprocate on the base 8 through the transmission of the transmission gear 1, so that the conveyor belt 7 drives the sliding seat 811 to reciprocate on the base 8. During the process of handling the panel 9, the panel 9 is placed on the handling support 812, and the handling support 812 is driven to reciprocate by the sliding seat 811 to realize the support and handling of the panel 9. Further, a number of buffer protection pads 813 are provided on the side of the handling support 812 facing the panel 9 to protect the surface of the panel 9 from being damaged by the handling support 812. Furthermore, buffer limit blocks 821 are provided at both ends of the slide rail 82 to buffer the sliding seat 811 and prevent the sliding seat 811 from falling off the base 8, ensuring the stability of the panel 9 handling operation.

[0061] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
