Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to an automatic feeding device for the upper cover plate of a motor gearbox. Background Technology

[0002] The motor shaft uses multi-stage transmission gears to progressively reduce speed or increase speed, significantly altering the output speed and torque. In the assembly and production of motor gearboxes, [the following is used]... Figure 1 Assembling the top cover plate onto the motor assembly is a critical process. The top cover plate has a special shape and several feature holes, including mounting holes for mounting the gear shaft, oblong holes for the output shaft to extend out, and fixing holes for securing the top cover plate.

[0003] Because the top cover plate has an irregular shape and lacks a central positioning hole, it is impossible to determine its angle using traditional feeding methods such as vibratory feeders, necessitating an additional positioning step during the feeding process. Currently, the top cover plate's posture is mainly corrected manually, which is costly and prone to affecting the quality and efficiency of subsequent assembly processes due to operator fatigue and differences in experience, thus hindering the realization of fully automated assembly. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide an automatic feeding device for the upper cover plate of a motor gearbox, so as to realize the automatic feeding of the upper cover plate in batches, and thus realize fully automated assembly.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An automatic feeding device for the top cover of a motor gearbox is disclosed. The top cover has a slotted feature hole and several notches along its edge. The device includes a storage rack and a pushing mechanism.

[0007] The storage rack is equipped with a storage cavity, and several top cover plates are stacked vertically in the storage cavity. The storage cavity is equipped with a positioning rod that matches the notch and an auxiliary positioning pin that is inserted into the waist-shaped feature hole. The upper end of the storage cavity is equipped with an inlet for loading the top cover plates, and the lower end of the storage cavity is equipped with an outlet for unloading the top cover plates.

[0008] The pushing mechanism includes a push plate disposed at the discharge port, the push plate being provided with a groove for accommodating a single upper cover plate, and the push plate being switchable between a first position and a second position;

[0009] When the push plate is in the first position, the groove receives the bottom cover plate of the storage cavity;

[0010] When the push plate is in the second position, the upper cover plate in the groove is pushed out laterally, and the discharge port is blocked by the push plate.

[0011] As an optional solution, the storage rack includes several vertically spaced frame blocks. The frame blocks have through holes that match the shape of the upper cover plate. Adjacent frame blocks are connected by several vertical rods. Positioning rods are fixed to the frame blocks and located at the edge of the through holes. Auxiliary positioning pins are inserted into the through holes.

[0012] As an alternative, a locking pin is provided on the bottom frame block of the storage rack to prevent the bottom cover plate of the storage cavity from falling.

[0013] As an alternative, the auxiliary positioning pin and locking pin are used when the top cover is installed into the storage cavity and removed when the top cover is normally removed from the storage cavity.

[0014] As an optional solution, the pushing mechanism includes a fixed base located below the storage rack, a linear guide rail on the fixed base, a transfer seat mounted on the linear guide rail, a push plate mounted on the transfer seat, and a first drive cylinder on the fixed base. The first drive cylinder is used to drive the transfer seat to reciprocate along the linear guide rail, so that the push plate switches between a first position and a second position.

[0015] As an alternative, the transfer seat is equipped with a second drive cylinder located below the push plate. The output shaft of the second drive cylinder faces vertically upward, and the second drive cylinder is used to lift the upper cover plate in the groove to a set height.

[0016] As an optional solution, the automatic feeding device for the motor gearbox cover also includes a material transfer mechanism, which is used to remove the cover at a set height. The material transfer mechanism includes a three-axis drive module, and the output end of the three-axis drive module is equipped with a suction cup for adsorbing the cover.

[0017] The beneficial effects of this utility model are:

[0018] This automatic feeding device for the motor gearbox cover plate achieves precise positioning of specially shaped cover plates by adapting the positioning rod and notch in the storage rack and inserting the auxiliary positioning pin into the waist-shaped feature hole. This effectively solves the problem that existing methods cannot accurately feed automatically. In particular, the cooperation between the pushing mechanism and the storage rack enables the automatic, continuous, single-piece, and uniform feeding of the cover plates without manual correction, which significantly improves feeding efficiency and reliability, facilitating subsequent automated assembly.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Figure 1 The upper cover plate 100 has a waist-shaped feature hole 101 and several notches 102 along its edge. For workpieces with this special shape, traditional feeding methods such as vibratory feeders are unsuitable, as they cannot guarantee consistent output posture. Therefore, as... Figure 2 and Figure 3 As shown, this utility model provides an automatic feeding device for the upper cover plate of a motor gearbox, including a storage rack 1 and a pushing mechanism 2, wherein:

[0032] The storage rack 1 is provided with a storage cavity 11, and several upper cover plates 100 are stacked vertically in the storage cavity 11. The storage cavity 11 is provided with a positioning rod 12 adapted to the notch 102 and an auxiliary positioning pin 13 inserted into the waist-shaped feature hole 101. The upper end of the storage cavity 11 is provided with an inlet for loading the upper cover plates 100, and the lower end of the storage cavity 11 is provided with an outlet for unloading the upper cover plates 100.

[0033] The pushing mechanism 2 includes a push plate 21 disposed at the discharge port. The push plate 21 is provided with a groove for accommodating a single upper cover plate 100. The push plate 21 can switch between a first position and a second position.

[0034] When the push plate 21 is in the first position, the groove receives the lowermost upper cover plate 100 of the storage cavity 11;

[0035] When the push plate 21 is in the second position, the upper cover plate 100 in the groove is pushed out laterally, and the discharge port is blocked by the push plate 21.

[0036] Thus, by adapting the positioning rod 12 and the notch 102 in the storage rack 1 and by inserting the auxiliary positioning pin 13 into the waist-shaped feature hole 101, the precise positioning of the special-shaped upper cover plate 100 is achieved, effectively solving the problem that the existing method cannot accurately and automatically feed materials. Among them, the cooperation between the pushing mechanism 2 and the storage rack 1 enables the automatic, continuous, single-piece and uniform feeding of the upper cover plate 100 without manual correction, which significantly improves the feeding efficiency and reliability, so as to facilitate subsequent automated assembly.

[0037] In at least one embodiment, the storage rack 1 includes a plurality of vertically spaced frame blocks 14, each frame block 14 having through holes 15 adapted to the shape of the upper cover plate 100, adjacent frame blocks 14 being connected by a plurality of vertical rods 16, a positioning rod 12 being fixed to the frame block 14 and located at the edge of the through hole 15, and an auxiliary positioning pin 13 being inserted into the through hole 15.

[0038] The frame block 14 and the vertical rod 16 combine to form a cage-like storage rack 1, which has a simple and stable structure and can stably load multiple layers of top cover plates 100, thereby increasing storage capacity. The through hole 15 is adapted to the shape of the top cover plate 100, and together with the positioning rod 12 and the auxiliary positioning pin 13, it can accurately limit the placement position of the top cover plate 100 and ensure stacking coaxiality. The through hole 15 on the frame block 14, which is adapted to the shape of the top cover plate 100, together with the positioning rod 12 and the auxiliary positioning pin 13, can realize the posture correction of each top cover plate 100 during the storage stage, ensuring accurate output of each top cover plate 100 in the future.

[0039] Furthermore, a locking pin 17 is provided on the lowest frame block 14 of the storage rack 1, which is used to restrict the lowermost upper cover plate 100 of the storage cavity 11 from falling.

[0040] The locking pin 17 can mechanically support the weight of the entire stack of top cover plates 100, effectively preventing the top cover plates 100 from falling automatically in case the pushing mechanism 2 is not installed in place or other unexpected situations, causing damage or safety hazards. It should be noted that the auxiliary positioning pin 13 and the locking pin 17 are used when the top cover plates 100 are inserted into the storage cavity 11 and are removed when the storage cavity 11 is normally outputting the top cover plates 100, so as to avoid affecting the sequential output of each top cover plate 100.

[0041] In at least one embodiment, the pushing mechanism 2 includes a fixed base 22 disposed below the storage rack 1, a linear guide rail 23 disposed on the fixed base 22, a transfer seat 24 mounted on the linear guide rail 23, a push plate 21 disposed on the transfer seat 24, and a first driving cylinder 25 disposed on the fixed base 22. The first driving cylinder 25 is used to drive the transfer seat 24 to reciprocate along the linear guide rail 23, so that the push plate 21 switches between a first position and a second position.

[0042] The linear guide rail 23 guides the transfer seat 24 to move, ensuring that the movement trajectory of the push plate 21 is smooth and accurate, and improving the consistency of the pushing position; the first drive cylinder 25 provides fast response and stable power, enabling the push plate 21 to switch quickly between the first position (receiving material) and the second position (outputting material), resulting in high pushing efficiency.

[0043] Furthermore, a second drive cylinder 26 is provided on the transfer seat 24 below the push plate 21. The output shaft of the second drive cylinder 26 is vertically upward. The second drive cylinder 26 is used to lift the upper cover plate 100 in the groove to a set height.

[0044] The lifting function of the second drive cylinder 26 eliminates the need for the subsequent material transfer mechanism 3 to descend significantly, simplifying the motion trajectory, improving the part picking efficiency, and reducing the risk of interference between mechanisms.

[0045] Optionally, the automatic feeding device for the upper cover of the motor gearbox also includes a material transfer mechanism 3, which is used to remove the upper cover 100 at a set height. The material transfer mechanism 3 includes a three-axis drive module 31, and the output end of the three-axis drive module 31 is provided with a suction cup 32 for adsorbing the upper cover 100.

[0046] The three-axis drive module 31 can drive the suction cup 32 to move flexibly in the XYZ directions, accurately transporting the upper cover plate 100 to the assembly station, adapting to the assembly needs of different positions. The suction cup 32's adsorption method does not damage the surface of the upper cover plate 100 during material handling, and the adsorption is firm, preventing it from falling off during the transfer process, replacing manual operation, and greatly improving the overall material loading efficiency. The three-axis drive module 31 is existing technology and will not be described in detail here.

[0047] In summary, the automatic feeding device for the motor gearbox cover plate achieves precise angle control and storage of the specially shaped cover plate 100 by adapting the positioning rod 12 of the storage rack 1 to the notch 102 and inserting the auxiliary positioning pin 13 into the waist-shaped feature hole 101, so as to ensure that each cover plate 100 is output with a uniform posture. The pushing mechanism 2 relies on the linear guide rail 23, the first driving cylinder 25 and the second driving cylinder 26, and cooperates with the storage rack 1 to realize the continuous discharge of a single cover plate 100. The transferring mechanism 3 can flexibly and without damage transport the cover plate 100 to the assembly station through the three-axis drive module 31 and the suction cup 32, further improving the picking and placing accuracy and process connection efficiency.

[0048] The overall design takes into account positioning accuracy, operational safety, and automation efficiency, effectively solving the positioning problems and reliance on manual labor in traditional feeding, significantly reducing interference risks and workpiece damage, adapting to subsequent automated assembly requirements, providing a stable and efficient feeding solution for the mass production of motor gearboxes, and providing reliable technical support for the design of fully automated production lines.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
