Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure.

[0053] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms “a,” “an,” “an,” “the,” and similar words used in this application do not indicate quantity limitation and may indicate singular or plural. The terms “comprising,” “including,” “having,” and any variations thereof used in this application are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or modules (units) is not limited to the listed steps or units, but may also include steps or units not listed, or may include other steps or units inherent to these processes, methods, products, or devices. The terms “connected,” “linked,” “coupled,” and similar words used in this application are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. “Multiple” used in this application refers to two or more. “And / or” describes the relationship between related objects, indicating that three relationships may exist; for example, “A and / or B” can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following objects are in an "or" relationship. The terms "first," "second," and "third" used in this application are merely to distinguish similar objects and do not represent a specific ordering of objects. "Above," "below," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0054] As used herein, “parallel” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°.

[0055] It should be understood that when a layer or element is referred to as being on another layer or substrate, it can mean that the layer or element is directly on the other layer or substrate, or that there is an intermediate layer between the layer or element and the other layer or substrate.

[0056] This document describes exemplary embodiments with reference to sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and regions is enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Therefore, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. Thus, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0057] The speed reducer in the robot is located below the robot body. Disassembling or assembling the speed reducer requires lifting the entire robot to create sufficient space underneath. Currently, disassembling and installing the speed reducer in robots requires building complex support structures. For example, when lifting the robot body, four hydraulic jacks are used to lift the perimeter of the robot body. Because the lifting is manually controlled, it is easy for the lifting speed and distance of the perimeter (such as the four sides) to be different, resulting in imbalance during the lifting process. This causes the robot body to sway, is time-consuming and labor-intensive, and has a low safety factor.

[0058] In addition, the current equipment for disassembling and assembling robot speed reducers wastes manpower when moving and poses certain safety risks during handling.

[0059] To address the aforementioned problems in the related art, in a first aspect, embodiments of the present invention provide an auxiliary fixture, such as... Figure 1-8 As shown, the device is used to assist in the assembly and disassembly of the drive mechanism installed below the machine body. It includes a lifting mechanism 1 and a fixing mechanism 2, which are detachably connected. The upper part of the fixing mechanism 2 is used to fix the machine body. The lifting mechanism 1 is located below the fixing surface of the fixing mechanism 2, away from the fixing surface of the fixing mechanism 2. The lifting mechanism 1 can push the fixing mechanism 2 to lift the machine body to a set distance from its original position so as to facilitate the assembly and disassembly of the drive mechanism.

[0060] The machine body, under the control of a drive mechanism, can transfer the display panel from the placement clamp to the process chamber, and then from the process chamber back to the placement clamp. This drive mechanism can be a speed reducer. The set distance is 15-20 cm.

[0061] The auxiliary fixture provided in this embodiment, by setting up a lifting mechanism 1 and a fixing mechanism 2, can assist in lifting the machine body, thereby facilitating the disassembly and assembly of the drive mechanism. This auxiliary fixture reduces or avoids the machine body's forward, backward, left, and right swaying during the lifting process, and only two people are needed to support, fix, and lift the machine body, reducing workload and minimizing the swaying problem caused by multiple operators, greatly improving operational efficiency and safety. Furthermore, compared to hydraulic jacks in related technologies, this auxiliary fixture is simpler to assemble and operate, thus reducing the manpower and material resources required for assembly and use, and consequently lowering the cost of assembly and use.

[0062] In some embodiments, such as Figure 2-5 As shown, the lifting mechanism 1 includes two sets of lifting platforms 10, which are arranged at intervals along the first direction X. Each lifting platform 10 includes a first support plate 101, at least two driving members 102, a connecting shaft 103, a second support plate 104, and a handwheel 105. At least two driving members 102 are arranged sequentially on the first support plate 101 along the second direction Y and are fixedly connected to the first support plate 101. The first direction X and the second direction Y intersect each other. Each driving member 102 includes a transmission wheel, a transmission rod A, and a lifting part B. The transmission wheel and the lifting part B are movably connected, and the transmission rod A passes through the lifting part B and is movably connected to it.

[0063] The transmission wheels of any two adjacent drive members 102 are connected by a connecting shaft 103; the transmission rod A is located on the side of the transmission wheel and the connecting shaft 103 away from the first support plate 101, and the extension direction of the transmission rod A is perpendicular to the plane formed by the intersection of the first direction X and the second direction Y; the transmission wheel of the outermost drive member 102 is connected to the handwheel 105; the rotation of the handwheel 105 can drive the transmission wheel and the connecting shaft 103 to rotate synchronously; the lifting part B can reciprocate along the extension direction Z of the transmission rod A under the drive of the transmission wheel.

[0064] The transmission rod A also passes through the second support plate 104 and the two are movably connected; the second support plate 104 and the lifting part B are fixedly connected by a fixing plate 106; the second support plate 104 can reciprocate along the extension direction Z of the transmission rod A under the drive of the lifting part B.

[0065] The first direction X and the second direction Y intersect each other perpendicularly. Both the first direction X and the second direction Y are defined according to the movement direction of the machine body when transferring the display panel.

[0066] In some embodiments, the driving component 102 controls the lifting platform 10 to perform lifting actions and reduces the resistance to personnel operation when the machine body rises. The driving component 102 is a worm gear reducer. Both the worm gear and the transmission wheel are located inside the housing of the driving component 102, and the transmission wheel is movably connected to the worm gear. The worm gear is movably connected to the lifting part B, that is, the transmission wheel and the lifting part B are indirectly movably connected; the worm refers to the combination of the transmission rod A and the lifting part B; the rotation of the transmission wheel can drive the worm gear to rotate, and the rotation of the worm gear can drive the worm to move. The movement of the worm gear is the reciprocating movement of the lifting part B along the extension direction of the transmission rod A. The lifting part B and the transmission rod A are connected by a nut thread fit. The specific internal structure and motion principle of the worm gear reducer are conventional technologies and will not be described in detail here.

[0067] In this embodiment, the lifting platform 10 includes two driving components 102. When the connecting shaft 103 rotates under the drive of the handwheel 105, it can drive the lifting part B in the other driving component 102, which is not directly connected to the handwheel 105, to move synchronously, thereby ensuring that the lifting parts B in the two driving components 102 move up or down synchronously. The first support plate 101 serves as a base for fixing the two driving components 102.

[0068] In this embodiment, a hole is provided in the second support plate 104, through which the transmission rod A passes, and the second support plate 104 can move up or down along the extension direction Z of the transmission rod A. The function of the second support plate 104 is to connect the two driving members 102 arranged along the second direction into one unit to form the lifting platform 10, and to support and fix the fixing mechanism 2 located above it. Since the contact area between the lifting part B of the driving member 102 and the second support plate 104 is small, a fixing plate 106 is needed to achieve a fixed connection between the two. The handwheel 105 controls the rising and falling movement of the lifting platform 10 by human operation. For example, rotating the handwheel 105 in the forward direction controls the lifting platform 10 to rise, and rotating the handwheel 105 in the reverse direction controls the lifting platform 10 to fall.

[0069] In some embodiments, such as Figure 2 and Figure 5 As shown, the lifting platform 10 also includes a scale 107 and at least four first foot cups 108. The scale 107 is disposed on the first support plate 101 and located at one end of the second support plate 104 on the side where the corresponding handwheel 105 is located. The extension direction of the scale 107 is parallel to the extension direction Z of the transmission rod A. A pointer C is disposed on one end face of the second support plate 104 on the side where the corresponding handwheel 105 is located. The pointer C can indicate different scales on the scale 107 as the second support plate 104 moves.

[0070] The first foot cup 108 is disposed on the side of the first support plate 101 away from the driving member 102, and the first foot cup 108 is fixedly connected to the first support plate 101. The first foot cup 108 is evenly distributed in the area of ​​the first support plate 101 corresponding to the driving member 102, and the first foot cup 108 can provide support for the first support plate 101.

[0071] In this embodiment, the readable ruler 107 is provided with a scale. When the second support plate 104 moves up or down along the extension direction Z of the transmission rod A under the drive of the lifting part B, the pointer C provided on one end face of the second support plate 104 indicates different scales on the scale 107, so as to clearly indicate how much distance the machine body has been raised or lowered.

[0072] In this embodiment, since there are other fixed components on the ground at the construction site, the first support plate 101 cannot be laid directly on the ground. Therefore, the first foot cup 108 is used to support the bottom of the first support plate 101.

[0073] In some embodiments, when the handwheel 105 rotates one revolution clockwise or counterclockwise, the lifting part B rises or falls 1-2 mm along the extension direction Z of the transmission rod A.

[0074] The two sets of lifting platforms 10, spaced apart along the first direction X, require two people to operate them, each turning a handwheel 105 on one set of lifting platforms 10. Considering the uncertainty of manually controlling the balance of the two sets of lifting platforms 10, the reduction ratio of the drive unit 102 (i.e., the worm gear reducer) is set to 1:6. Calculations based on the reduction ratio and lead ratio of the worm gear reducer show that each rotation of the handwheel 105 results in a 2mm increase or decrease in the lifting distance of the lifting platform 10. This relatively small increase in lifting distance per rotation of the handwheel 105 ensures that the deviation in the distance the two sets of lifting platforms 10 are raised or lowered due to differences in operating speed is kept within a small range (i.e., within 1-2mm). This reduces or avoids lateral swaying of the machine body along the first direction X during lifting or lowering, ensuring the balance of the machine body during the lifting or lowering process, and thus ensuring operational efficiency and safety.

[0075] In some embodiments, the drive member 102 further includes a housing D and a self-locking structure. The self-locking structure and the transmission wheel are both disposed within the housing D. The self-locking structure is used to lock the position of the lifting part B when it moves to any position along the extension direction Z of the transmission rod A.

[0076] The self-locking structure uses a self-locking screw (a built-in structure in worm gear reducers), which prevents the machine body from falling due to gravity when it rises.

[0077] In some embodiments, such as Figures 6-8As shown, the fixing mechanism 2 includes at least two sets of fixing support structures 20, which are arranged sequentially at intervals along the second direction Y, and the two ends of each set of fixing support structures 20 are respectively attached to the two sets of lifting platforms 10.

[0078] In this embodiment, two sets of fixed support structures 20 are provided. The fixed support structures 20 are connected to both the machine body and the lifting platform 10, respectively, and are used to control the machine body by the lifting platform 10, and to fix and support the machine body. At least two sets of fixed support structures 20 are arranged sequentially at intervals along the second direction Y, which can reduce or avoid the back-and-forth swaying of the machine body along the second direction Y when it is lifted or lowered, ensuring the balance of the machine body during the lifting or lowering process, thereby ensuring operational efficiency and safety.

[0079] In some embodiments, the fixed support structure 20 includes a support beam 201, a perforated fixing plate 202, a plurality of first connecting plates 203 and a plurality of second connecting plates 204; both ends of the support beam 201 are fixedly connected to the second support plates 104 of the two sets of lifting platforms 10 through at least two second connecting plates 204; the perforated fixing plate 202 is disposed on the side of the support beam 201 away from the lifting platform 10 and is fixedly connected to the support beam 201.

[0080] Multiple first connecting plates 203 are fixedly connected to the multi-hole fixing plate 202 respectively, and the multiple first connecting plates 203 are spaced apart from each other; the multiple first connecting plates 203 are used to detachably fix the machine body.

[0081] In this embodiment, each set of fixed support structures 20 is provided with three first connecting plates 203. The perforated fixing plate 202 is welded to the support beam 201. The perforated fixing plate 202 has multiple connecting holes. When the first connecting plate 203 is connected to the support beam 201, its position can be adjusted through the connecting holes at different locations in the perforated fixing plate 202 to adapt to different machine body models and site conditions. The function of the first connecting plate 203 is to fix and connect the machine body. The machine body has pre-drilled connection holes, and the first connecting plate 203 is connected to the machine body using bolts. During connection, the first connecting plate 203 is first connected to the machine body, and then the first connecting plate 203 is connected to the perforated fixing plate 202 on the support beam 201 using bolts.

[0082] The second connecting plate 204 is a connecting plate that connects the support beam 201 and the second support plate 104. The second connecting plate 204 is welded to the support beam 201. The second connecting plate 204 is fixedly connected to the connecting plate welded on the second support plate 104 by bolts, thereby realizing the assembly connection between the lifting mechanism 1 and the fixed mechanism 2.

[0083] In some embodiments, such as Figures 6-8 As shown, the perforated fixing plate 202 extends along the length of the supporting crossbeam 201. Multiple connecting holes E are provided on the perforated fixing plate 202, and these holes E are distributed at different positions along the extension direction of the perforated fixing plate 202. The connection position between the first connecting plate 203 and the perforated fixing plate 202 can be adjusted according to the position of the connecting holes E in the perforated fixing plate 202 to adapt to different machine models and site conditions.

[0084] The length direction of the supporting beam 201 is the first direction X.

[0085] In some embodiments, the fixed support structure 20 further includes a plurality of support members 205 disposed below the support beam 201 and located between the two sets of lifting platforms 10. One end of the support member 205 contacts the support beam 201 and the other end contacts the ground. The support member 205 is used to indirectly support the machine body. The plurality of support members 205 are arranged at intervals or continuously along the length direction of the support beam 201.

[0086] After the machine body is raised to a certain position using the handwheel 105, a support member 205 is manually placed under the machine body for support. The function of the support member 205 is to provide auxiliary support to the machine body after it has been raised to a certain position, so as to prevent the machine body from falling due to the failure of the self-locking condition of the drive component 102 (i.e., the worm gear reducer).

[0087] In some embodiments, such as Figure 1 and Figure 6 As shown, the support member 205 includes a sleeper F, a metal plate G, and a second foot cup H. The metal plate G is connected between the sleeper F and the second foot cup H. One end of the sleeper F is in contact with the support beam 201. The second foot cup H is in contact with the ground, and the height of the second foot cup H is adjustable.

[0088] The height of the second foot cup H can be adjusted to accommodate the fixing of machine bodies of different heights.

[0089] In this embodiment, by setting two sets of lifting platforms 10 and two sets of fixed support structures 20, the left and right lifting amount along the first direction X and the front and back lifting amount along the second direction Y when the machine body is lifted or lowered can be controlled, thereby ensuring the stability of the machine body when it is lifted or lowered by the auxiliary fixture; and the auxiliary fixture can be operated by two people turning the handwheel 105.

[0090] In some embodiments, in this auxiliary fixture, any two fixedly connected structures can be connected by bolts, screws, nuts, or welding, etc., which will not be elaborated further.

[0091] Secondly, based on the above-described structure of the auxiliary fixture, this disclosure also provides an assembly method for the auxiliary fixture, including: in use, assembling the lifting mechanism and the fixing mechanism respectively, and then fixing the fixing mechanism to the machine body; and then fixing the fixing mechanism to the lifting mechanism.

[0092] Once the fixed connection is completed, the auxiliary fixture can be used to raise or lower the machine body, thereby enabling the disassembly and installation of the drive mechanism below the machine body.

[0093] In some embodiments, such as Figure 9 As shown, the assembly method of the auxiliary fixture also includes: when not in use, disassembling the connection between the fixing mechanism 2 and the machine body, and then disassembling the connection between the fixing mechanism 2 and the lifting mechanism 1;

[0094] Install casters 3 at the end of the fixed mechanism 2, place the lifting mechanism 1 on the fixed mechanism 2, and fix the lifting mechanism 1 and the fixed mechanism 2 together.

[0095] Among them, such as Figure 9 As shown, casters 3 are installed below the end of the support beam 201 in the fixing mechanism 2 and below the second connecting plate 204 connected to the end of the support beam 201; the lifting mechanism 1 is placed above the support beam 201 in the fixing mechanism 2, and the first support plate 101 in the lifting mechanism 1 and the perforated fixing plate 202 fixed on the support beam 201 are fixedly connected by bolts.

[0096] In this embodiment, when not in use, the auxiliary fixture's structural components can be reassembled and casters 3 installed. By installing casters 3, the auxiliary fixture can be directly pushed and moved, thus avoiding wasted manpower during movement and reducing safety risks during handling. This assembly scheme for the auxiliary fixture when not in use, through the installation of casters 3, solves the problem of difficulty in moving the heavy fixture. It also solves the problem of easily lost parts after use.
