Description

Technical Field

[0001] The present application relates to the technical field of product assembly and processing, and in particular to a centering assembly tool. Background Art

[0002] The popularity of smart interactive display devices such as tablets, all-in-one machines, and conference screens has greatly facilitated people's lives, studies, work, and entertainment. In the manufacturing process of smart interactive display devices, the light board and the bottom shell are assembled and fixed together by screws. Currently, workers manually position and center the light board and the bottom shell, and then manually and in combination with equipment complete the installation of multiple screws.

[0003] However, since the mounting holes on the light board and the bottom shell are designed with a certain hole position tolerance, and manual errors are prone to occur in the manual positioning of the light board and the bottom shell, the combination of these two factors will result in that although the bottom shell and the light board can be fixed normally by screwing, the positioning accuracy between the bottom shell and the light board cannot be guaranteed. After the two are assembled into one, there will be deviations of varying sizes in the up, down, left and right directions, which will produce a matching gap, causing poor display of light and dark lines, affecting the quality of the equipment's finished products, and the manual positioning has low operating efficiency and high output costs. Summary of the invention

[0004] Based on this, it is necessary to provide a centering assembly tool to address the problem that poor display of light and dark lines affects the quality of equipment products and manual operation efficiency is low.

[0005] The present application provides a split assembly tool, which includes:

[0006] A tooling seat body, wherein the tooling seat body is provided with a receiving portion, and the receiving portion is configured to receive the bottom shell and the lamp panel to be assembled;

[0007] A first pushing mechanism and a first centering mechanism, wherein the first pushing mechanism and the first centering mechanism are arranged on opposite sides of the tooling seat body in a first direction with a spacing therebetween; and

[0008] A second pushing mechanism and a second centering mechanism, wherein the second pushing mechanism and the second centering mechanism are arranged on opposite sides of the tooling seat body in a second direction, the second direction intersects the first direction;

[0009] Among them, the first pushing mechanism is used to push the bottom shell and the light board toward the first centering mechanism and the second pushing mechanism is used to push the bottom shell and the light board toward the second centering mechanism, so as to realize the pre-assembly alignment of the bottom shell and the light board, and the first centering mechanism is used to push the bottom shell toward the first pushing mechanism and the second centering mechanism is used to push the bottom shell toward the second pushing mechanism, so that the bottom shell is displaced relative to the light board to realize the centering positioning of the bottom shell and the light board.

[0010] When the centering assembly tooling of the present scheme is working, the lamp board and the bottom shell to be assembled are stacked in sequence and placed on the accommodating part of the tooling seat body, and then the first pushing mechanism and the second pushing mechanism are controlled to act, the first pushing mechanism pushes the bottom shell and the lamp board toward the first centering mechanism and the second pushing mechanism pushes the bottom shell and the light board toward the second centering mechanism, so that the four sides of the bottom shell and the light board are simultaneously in contact with the first pushing mechanism, the second pushing mechanism, the first centering mechanism and the second centering mechanism, so that the bottom shell and the light board that are initially placed on the accommodating part and are not aligned properly can be assembled and aligned, for example, the preliminary alignment of the through hole on the bottom shell and the threaded hole on the lamp board is completed, but because the through hole and the threaded hole are designed with a certain size of hole position tolerance, the through hole and the threaded hole cannot be truly coaxially arranged at this time, which causes the four sides of the bottom shell to be aligned with the four sides of the lamp board. Deviations of varying sizes exist along the edges, resulting in fitting gaps, which can easily cause the problem of poor display of light and dark lines. To address this, the first centering mechanism is further operated to push the bottom shell to move relative to the light board along a first direction, and the second centering mechanism is operated to push the bottom shell to move relative to the light board along a second direction, thereby achieving precise adjustment and centering of the relative positions of the bottom shell and the light board, that is, the through hole and the threaded hole can be adjusted to a coaxial arrangement relationship, while eliminating the deviations of varying sizes between the four sides of the bottom shell and the four sides of the light board, eliminating the fitting gap, solving the problem of poor display of light and dark lines, and ensuring the quality of the finished product of the display device subsequently equipped with the bottom shell and the light board.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0033] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0034] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0037] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0038] In the manufacturing process of the intelligent interactive display device, there is a processing step in which the light board 300 and the bottom shell 200 are assembled and fixed into one by screws. Currently, workers mainly manually position and center the light board 300 and the bottom shell 200, and then tighten and install multiple screws manually or manually in combination with equipment.

[0039] However, since the threaded holes on the light board 300 and the through holes on the bottom shell 200 are designed with a certain size of hole position tolerance, and manual errors are prone to occur in the manual positioning of the light board 300 and the bottom shell 200, the combination of these two factors will result in that although the bottom shell 200 and the light board 300 can be fixed normally by screwing screws (in order to facilitate the insertion of screws, the aperture of the through hole on the bottom shell 200 is generally larger than the diameter of the screw, so even if the center line of the through hole and the center line of the threaded hole are deviated to a certain extent and are not coaxially arranged, the screw can still pass through the through hole and be normally inserted into the threaded hole). Precisely because the through hole and the threaded hole do not form a precise alignment of coaxial arrangement, the positioning accuracy between the bottom shell 200 and the light board 300 cannot be guaranteed. After the two are assembled into one, there will be deviations of varying sizes in the up, down, left and right directions, resulting in a matching gap, causing poor display of light and dark lines, affecting the quality of the finished equipment, and the manual positioning has low operating efficiency and high output costs.

[0040] In view of the above problems, the present invention adopts an automated centering assembly tool 100 to realize the automatic centering assembly of the bottom shell 200 and the light board 300, and adopts a first pushing mechanism 20 to push the bottom shell 200 and the light board 300 to actively abut against the first centering mechanism 30, and at the same time, a second pushing mechanism 40 pushes the bottom shell 200 and the light board 300 to actively abut against the second centering mechanism 50, so as to realize the automatic preliminary alignment of the bottom shell 200 and the light board 300 from the intersecting first direction and second direction, at which time the through hole and the threaded hole are basically aligned, but there is still a gap that allows On this basis, the first centering mechanism 30 and the second centering mechanism 50 are further used to push the bottom shell 200 along the first direction and the second direction respectively to perform a slight displacement relative to the light board 300 (such as moving a distance of several threads), so as to complete the high-precision alignment of the bottom shell 200 and the light board 300, that is, to achieve the coaxial arrangement of the through hole and the threaded hole, and at the same time, the four sides of the bottom shell 200 are evenly aligned with the four sides of the light board 300, eliminating the gap caused by the matching deviation, and then causing the problem of poor display of bright and dark lines.

[0041] See Figures 1 to Figure 4 , which is a centering assembly tool 100 shown in an embodiment of the present application, is used in processing scenarios for positioning and assembling the bottom shell 200 and the light board 300. That is, when the centering assembly tool 100 completes the centering positioning of the bottom shell 200 and the light board 300, the through hole on the bottom shell 200 and the threaded hole on the light board 300 are coaxially arranged, and at the same time, the four sides of the bottom shell 200 and the four sides of the light board 300 are evenly aligned and tightly matched, and then a screw driving device is used to automatically screw the screws into each group of aligned through holes and threaded holes, so that the bottom shell 200 and the light board 300 can be locked and fixed as a whole, so that they can be transferred to the next assembly link as accessories for display device production.

[0042] The display device can be any one of, but not limited to, a conference screen, an all-in-one machine, a television, etc., and can be selected according to actual needs.

[0043] Exemplarily, the centering assembly tool 100 includes a tool base body 10 , a first pushing mechanism 20 , a first centering mechanism 30 , a second pushing mechanism 40 and a second centering mechanism 50 .

[0044] The tooling seat body 10 is provided with a receiving portion 11, which is configured to receive the bottom shell 200 and the light board 300 to be assembled. For example, the tooling seat body 10 in the present application is a rectangular block structure made of metal material, which has a simple structure and high strength, is easy to manufacture, and has low cost.

[0045] The tooling seat body 10 has a first direction, a second direction and a third direction. Specifically, the first direction is the X-axis direction, which can also be regarded as the length direction of the tooling seat body 10; the second direction is the Y-axis direction, which can also be regarded as the width direction of the tooling seat body 10; the third direction is the Z-axis direction, which can also be regarded as the height direction of the tooling seat body 10.

[0046] The first pushing mechanism 20 and the first centering mechanism 30 are arranged on opposite sides of the first direction of the tooling seat body 10 at intervals; the second pushing mechanism 40 and the second centering mechanism 50 are arranged on opposite sides of the second direction of the tooling seat body 10 at intervals, and the second direction intersects with the first direction.

[0047] That is, the first pushing mechanism 20, the second pushing mechanism 40, the first centering mechanism 30 and the second centering mechanism 50 are arranged around the periphery of the accommodating portion 11 and are distributed in a rectangular shape. Such a structural arrangement can be suitable for the abutment and positioning needs of the lamp panel 300 and the bottom shell 200 which also have a rectangular shape.

[0048] Among them, the first pushing mechanism 20 is used to push the bottom shell 200 and the light board 300 toward the first centering mechanism 30 and the second pushing mechanism 40 is used to push the bottom shell 200 and the light board 300 toward the second centering mechanism 50, so as to realize the pre-assembly alignment of the bottom shell 200 and the light board 300, the first centering mechanism 30 is used to push the bottom shell 200 toward the first pushing mechanism 20 and the second centering mechanism 50 is used to push the bottom shell 200 toward the second pushing mechanism 40, so that the bottom shell 200 is displaced relative to the light board 300 to realize the centering positioning of the bottom shell 200 and the light board 300.

[0049] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: when the centering assembly tool 100 of this solution is working, the lamp board 300 and the bottom shell 200 to be assembled are stacked in sequence on the accommodating portion 11 of the tool seat body 10, and then the first pushing mechanism 20 and the second pushing mechanism 40 are controlled to act, the first pushing mechanism 20 pushes the bottom shell 200 and the lamp board 300 toward the first centering mechanism 30, and the second pushing mechanism 40 pushes the bottom shell 200 and the lamp board 300 toward the second centering mechanism 50, so that the four sides of the bottom shell 200 and the lamp board 300 are simultaneously aligned with the first pushing mechanism 20 and the second pushing mechanism 40. The pushing mechanism 40, the first centering mechanism 30 and the second centering mechanism 50 are abutted at the same time, so that the bottom shell 200 and the lamp board 300 that are initially placed on the accommodating portion 11 and are not properly aligned can be assembled and aligned, for example, the through hole on the bottom shell 200 and the threaded hole on the lamp board 300 are initially aligned. However, since the through hole and the threaded hole are designed with a certain size of hole position tolerance, the through hole and the threaded hole cannot be truly coaxially arranged at this time, resulting in unequal deviations between the four sides of the bottom shell 200 and the four sides of the lamp board 300, thereby generating a matching gap, which can easily cause the problem of poor display of light and dark lines.

[0050] In view of this, by further operating the first centering mechanism 30 to push the bottom shell 200 to move relative to the light board 300 along the first direction, and operating the second centering mechanism 50 to push the bottom shell 200 to move relative to the light board 300 along the second direction, the relative positions of the bottom shell 200 and the light board 300 can be accurately adjusted and aligned, that is, the through hole and the threaded hole can be adjusted to a coaxial arrangement relationship, and at the same time, the unequal deviations between the four sides of the bottom shell 200 and the four sides of the light board 300 can be eliminated, the fitting gap can be eliminated, the problem of poor display of bright and dark lines can be solved, and the quality of the finished product of the display device subsequently installed with the bottom shell 200 and the light board 300 can be ensured; and the centering assembly work completes the centering assembly of the bottom shell 200 and the light board 300 through semi-automatic or fully automatic control, which significantly improves the working efficiency compared with traditional manual operation, and helps to reduce output costs.

[0051] In one embodiment, the tooling seat body 10 has a top surface and a bottom surface, and the top surface and the bottom surface are spaced and arranged opposite to each other along the third direction of the tooling seat body 10. That is, in the height direction (i.e., the Z-axis direction) of the tooling seat body 10, the top surface is arranged above the bottom surface, and the top surface is set as a receiving portion 11, and the receiving portion 11 is provided with a recessed cavity 12 formed by being recessed toward the bottom surface. That is, the lamp board 300 and the bottom shell 200 can be placed directly on the top surface, and the placement method is simple. The top surface is a flat surface and an open structure with no obstructions on all sides, so there will be no obstruction or interference to the actions of the first pushing mechanism 20, the second pushing mechanism 40, the first centering mechanism 30, and the second centering mechanism 50. The recessed cavity 12 has a weight-reducing effect, realizing a lightweight design of the centering assembly tool 100.

[0052] Please continue to refer to Figures 1 and 2. Specifically, in an optional embodiment, the first pushing mechanism 20 and the second pushing mechanism 40 both include a carrier plate 20a, a push block assembly 20b and a power source 20c for outputting telescopic power. The carrier plate 20a is arranged on the side of the tooling seat body 10, the power source 20c is installed on the carrier plate 20a, and the telescopic shaft of the power source 20c is connected to the push block assembly 20b, and the push block assembly 20b is used to push the bottom shell 200 and the light board 300.

[0053] During installation, one end of the carrier plate 20a is fixed to the side bottom of the tooling seat body 10, and the installation method can be one of screw connection, clamping connection, etc. The other end of the carrier plate 20a extends to the outside of the tooling seat body 10 to form a suspension structure, and the upper plate surface of the suspension part of the carrier plate 20a provides space for the installation of the power source 20c. Then the push block assembly 20b is connected to the telescopic shaft of the power source 20c. When the light board 300 and the bottom shell 200 are stacked and placed on the accommodating portion 11 in sequence, the two power sources 20c in the first direction and the second direction drive the push block assembly 20b to extend, and the push block assembly 20b abuts against the same side of the bottom shell 200 and the light board 300, so that the bottom shell 200 and the light board 300 that are not aligned in the height direction can be adjusted to be basically aligned.

[0054] In the above embodiment, the push block assembly 20b includes a support block 21b, an elastic unit 22b and a push block 23b. The support block 21b is connected to the telescopic shaft of the power source 20c, and the push block 23b is elastically telescopically connected to the support block 21b through the elastic unit 22b. The support block 21b is connected to the telescopic shaft of the power source 20c, and is used to transmit the telescopic power of the telescopic shaft to the push block 23b, so that the push block 23b abuts against the bottom shell 200 and the light board 300 to complete the preliminary alignment adjustment. The elastic unit 22b is connected to the push block 23b and the support block 21b bracket, so that the push block 23b can elastically abut against the bottom shell 200 and the light board 300 to prevent rigid extrusion deformation or even damage to the bottom shell 200 and the light board 300.

[0055] For example, the elastic unit 22b includes a guide column and a spring, one end of the guide column is fixedly connected to the push block 23b, and the other end can be movably inserted into the preset through hole of the support block 21b, and the spring is sleeved outside the guide column and the two ends respectively contact the push block 23b and the support block 21b in a one-to-one manner. When the power source 20c drives the push block 23b to contact the bottom shell 200 and the light board 300, the spring is compressed and the guide column slides in the preset through hole, and the push block 23b approaches the support block 21b to form an elastic avoidance to the bottom shell 200 and the light board 300, so as to achieve the purpose of preventing the bottom shell 200 and the light board 300 from being rigidly squeezed.

[0056] Optionally, the power source 20c is any one of a pneumatic cylinder, an electric push rod, an oil cylinder, etc.

[0057] Please continue to refer to Figures 1 and 2, and Figure 4 and Figure 5 In addition, based on any of the above embodiments, the first centering mechanism 30 and the second centering mechanism 50 both include a centering fixed block 30a, a centering movable block 30b and an adjusting member 30c. The centering fixed block 30a is fixed to the tooling seat body 10, and the installation method can be at least one of screw connection, bonding, clamping, welding, etc. For example, in this embodiment, two bolts are respectively installed at the two ends of the centering fixed block 30a in the length direction and are screwed and fixed to the tooling seat body 10. The installation method is simple and the connection strength is high.

[0058] The adjusting member 30c is movably mounted on the centering fixed block 30a and connected to the centering movable block 30b. The adjusting member 30c is used to drive the centering movable block 30b to move relative to the centering fixed block 30a, so as to achieve the centering positioning of the bottom shell 200 and the light board 300. By operating the adjusting member 30c, the centering movable block 30b can be driven to extend and move relative to the centering fixed block 30a. The centering movable block 30b alone pushes the bottom shell 200 to move slightly relative to the light board 300 in the first direction and the second direction (such as moving a distance of several threads, where one thread is equal to 0.01 mm), so as to achieve high-precision centering positioning of the bottom shell 200 and the light board 300.

[0059] For example, the adjusting member 30c is an adjusting bolt, and the centering fixed block 30a is provided with a threaded hole that penetrates the structure. The adjusting bolt is screwed into the threaded hole, and the two ends of the adjusting bolt extend to the outside of the two openings of the threaded hole respectively, so as to be connected to the centering movable block 30b and facilitate the turning of the adjusting bolt.

[0060] In order to improve the smoothness of the extension and movement of the centering movable block 30b and thereby ensure the centering accuracy between the bottom shell 200 and the lamp board 300, on the basis of the above embodiment, a guide groove 31a is formed on the side of the centering fixed block 30a facing the accommodating portion 11, and the centering movable block 30b is arranged in the guide groove 31a and cooperates with the movable guide of the groove side wall of the guide groove 31a.

[0061] In addition, based on the above-mentioned embodiments, the first centering mechanism 30 and the second centering mechanism 50 also include a limit plate 30d, an elastic member 30e and a connecting pin 30f. The connecting pin 30f is movably arranged in the centering fixed block 30a in a direction close to or away from the accommodating portion 11, and the opposite ends of the connecting pin 30f respectively and one by one pass through the outside of the opposite sides of the centering fixed block 30a. One end of the connecting pin 30f is connected to the centering movable block 30b, and the other end of the connecting pin 30f is connected to the limit plate 30d. The elastic member 30e abuts between the centering fixed block 30a and the limit plate 30d. By adopting the limit plate 30d, the elastic member 30e and the connecting pin 30f to assemble and connect with the centering fixed block 30a and the centering movable block 30b, when the bottom shell 200 and the lamp board 300 are removed from the tooling seat body 10 after the centering and screw locking processing, and the adjusting bolt is turned in the reverse direction, the elastic member 30e applies elastic pulling force to the centering movable block 30b, so that the centering movable block 30b can be automatically reset.

[0062] Optionally, the elastic member 30e may be, but is not limited to, any one of a spring, an elastic column, a spring sheet, etc.

[0063] In order to more accurately realize the micro-displacement drive of the bottom shell 200 and complete the high-precision centering positioning of the bottom shell 200 and the light board 300, in one embodiment, the centering assembly tool 100 also includes a feeler gauge, and the centering movable block 30b has an active surface facing the bottom shell 200, and the active surface and the side wall of the bottom shell 200 are used to cooperate to form a centering gap, and the feeler gauge is used to insert the centering gap. For example, after the preliminary alignment of the bottom shell 200 and the lamp board 300 is completed by the first pushing mechanism 20 and the second pushing mechanism 40, assuming that the alignment tolerance between the threaded hole on the lamp board 300 and the through hole on the bottom shell 200 is ten threads, and five threads on a single radial side, a feeler gauge with a thickness of five threads is inserted into the centering gap between the active surface of the centering movable block 30b of the first centering mechanism and the bottom shell 200, and into the centering gap between the active surface of the centering movable block 30b of the second centering mechanism and the bottom shell 200, and then the centering movable block 30b is adjusted to push the feeler gauge against the side wall of the bottom shell 200, so as to achieve precise adjustment of the coaxial arrangement of the threaded hole and the through hole (i.e., five threads on a single radial side), thereby completing the centering positioning of the bottom shell 200 and the lamp board 300.

[0064] Please continue to refer to Figures 1 and 2. In addition, based on any of the above embodiments, the centering assembly tool 100 further includes at least one first clamping mechanism 60 and at least one second clamping mechanism 70. The first clamping mechanism 60 and the second clamping mechanism 70 are respectively arranged on the opposite side or adjacent side of the tool seat body 10, and are used to clamp or release the bottom shell 200 and the light board 300 in the accommodating portion 11. By simultaneously clamping the bottom shell 200 and the light board 300 by the first clamping mechanism 60 and the second clamping mechanism 70, it is possible to prevent the bottom shell 200 and the light board 300 from loosening and shifting during the automatic screwing process of the screw driving equipment, thereby affecting the normal assembly process.

[0065] Specifically, in an optional embodiment, the first clamping mechanism 60 and the second clamping mechanism 70 each include at least one clamping arm 60a and at least one clamping driver 60b for outputting rotational power, the clamping driver 60b is mounted on the side of the tooling seat body 10, the clamping arm 60a is connected to the clamping driver 60b in a one-to-one correspondence, and the clamping arm 60a has a clamping position and a release position; when in the clamping position, the clamping arm 60a is disposed directly above the accommodating portion 11 to clamp and fix the bottom shell 200 and the lamp board 300, and when in the release position, the clamping arm 60a is disposed outside the accommodating portion 11 to disengage from the bottom shell 200 and the lamp board 300. The first clamping mechanism 60 and the second clamping mechanism 70 have simple structural compositions and working principles, and the clamping arm 60a moves quickly and switches positions accurately. Not only can the bottom shell 200 and the lamp board 300 be reliably clamped and limited to the surface of the tooling seat body 10 during automatic screwing, but also different bottom shell 200 and lamp board 300 materials can be processed continuously, thereby improving production efficiency.

[0066] For example, the clamping driver 60b is a rotary cylinder, which is arranged vertically, and the rotating arm of the rotary cylinder is arranged upward to be fixedly connected to the pressing arm 60a, so that the pressing arm 60a can rotate in both directions in a horizontal plane parallel to the top surface of the tooling seat body 10. For example, when rotating in a clockwise direction, the pressing arm 60a can rotate from the outside of the accommodating portion 11 to just above the accommodating portion 11 to clamp the bottom shell 200 and the light board 300; when rotating in a counterclockwise direction, the pressing arm 60a can rotate from just above the accommodating portion 11 to the outside of the accommodating portion 11 to separate from the bottom shell 200, and then the first pushing mechanism 20 and the first centering mechanism 30 and the second pushing mechanism 40 and the second centering mechanism 50 move away from each other, and the bottom shell 200 and the light board 300, which are locked and fixed as an integral structure, are completely released from the constraints, so that they can be removed from the tooling seat body 10 and sent to the next process flow.

[0067] Taking into account the sliding contact friction between the pressing arm 60a and the bottom shell 200, in order to prevent the pressing arm 60a from scratching or squeezing and deforming the bottom shell 200, in an optional embodiment, the pressing arm 60a is made of a flexible material; or, in another optional embodiment, the side of the pressing arm 60a used for crimping the bottom shell 200 is provided with a flexible portion.

[0068] For example, the material of the pressure arm 60a and the flexible portion may be one of rubber, epoxy resin, and the like.

[0069] In addition, the centering assembly tool 100 further includes a control valve 80, which is controllably connected to the first pushing mechanism 20, the second pushing mechanism 40, the first clamping mechanism 60, and the second clamping mechanism 70. By operating the control valve 80, the first pushing mechanism 20, the second pushing mechanism 40, the first clamping mechanism 60, and the second clamping mechanism 70 can be controlled to move, that is, the first pushing mechanism 20 and the second pushing mechanism 40 first move to center the bottom shell 200 and the light board 300, and then the first clamping mechanism 60 and the second clamping mechanism 70 clamp the bottom shell 200 and the light board 300 to position them, ensuring that they do not loosen when the screws are screwed.

[0070] For example, the control valve 80 may be a manual valve, an electric control valve, etc., which can be flexibly selected according to actual needs.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
