Description
Technical Field
[0001] The utility model relates to the technical field of motor devices, in particular to a welding device for a frameless motor for a humanoid robot joint. Background Art
[0002] The disadvantages of frameless motors for humanoid robot joints during assembly are as follows:
[0003] 1) In the original welding method, the internal and external wires of the corresponding coils are welded to the corresponding wiring ports of U, V, and W in a fixed order. Because there are many internal and external wiring heads, it is easy to make wrong wiring terminals during the welding process.
[0004] 2) Too many wiring terminals cause confusion in the motor's internal wiring.
[0005] In response to this, there are structures on the market in which circuits are prefabricated in PCB boards, which are then fixed to the PCB boards and wire ends by welding. However, there is a lack of support between the PCB boards and the frame, resulting in poor stability and inconvenience for subsequent welding, which needs to be improved. Utility Model Content
[0006] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:
[0007] The present application document discloses a welding device for a frameless motor for a humanoid robot joint, comprising an annular PCB board, a card slot being arranged at the side of the PCB board, and a bracket, wherein the bracket comprises a top ring, a bottom ring, a connecting arm, and a reinforcing arm, wherein the top ring at the top and the top ring at the bottom are connected by a connecting arm, and adjacent connecting arms are connected by a reinforcing arm, the PCB board is fixed on the top ring, and a mounting hole is arranged on the bottom ring along the axial direction.
[0008] In this solution, the structure of the welding device is improved, and a bracket is added to the original PCB board. When installing on the motor, the bracket is abutted against the end face of the frame and fixed. After that, the wire end can be clamped in the slot and welded in sequence. The support of the bracket improves the stability of the PCB board, facilitates subsequent operations, and improves performance. The frame-type structure of the connecting arm with the top ring and bottom ring helps to dissipate heat and reduce weight, and the reinforcing arm helps to improve the structural strength.
[0009] Furthermore, the ring opening wall of the top ring is stepped, the PCB board is embedded and fixed in the ring opening and supported by the lower stepped surface. The stepped shape is convenient for docking with the PCB board, and can also be fixed for a second time by screws.
[0010] Furthermore, the top ring includes a plurality of parts, and the gaps between the parts correspond to the slots, so that the line segments can be easily inserted into the slots.
[0011] Furthermore, the card slot is L-shaped, a soldering point is arranged near the card slot, and a related circuit is preformed on the PCB board, and a required circuit is formed by welding with the soldering point.
[0012] Furthermore, the peripheral wall and the ring wall of the PCB board are provided with slots to facilitate docking with the terminals.
[0013] Furthermore, the bracket is integrally formed, which helps to simplify the assembly process.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. The utility model improves the structure of the welding device, and adds a bracket on the basis of the original PCB board, so as to improve the stability of the PCB board and facilitate subsequent operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Example 1
[0023] like Figure 1 , Figure 2 As shown, in this example, a welding device for a frameless motor for a humanoid robot joint includes a ring-shaped PCB board 1, on which the required circuit is prefabricated, and a slot 10 is formed at the side of the PCB board 1 to clamp the wire end to facilitate subsequent welding.
[0024] In this example, a bracket is added, and the bracket 2 is annular frame-shaped as a whole. Specifically, the bracket 2 includes a top ring 21, a bottom ring 23, a connecting arm 22, and a reinforcing arm 24. The top ring 21 and the bottom ring 23 are arranged up and down, and the top ring 21 at the top and the bottom ring 23 at the bottom are connected by the connecting arm 22, and the connecting arm 22 is like a longitudinal rod.
[0025] The left and right adjacent connecting arms 22 are connected by a reinforcing arm 24 , which is also rod-shaped and extends circumferentially. The PCB board 1 is fixed at the top ring 21 , such as by embedding, snapping or fastening with screws, preferably by embedding and fixing.
[0026] like Figure 1 As shown, the PCB board 1 is embedded and fixed at the ring opening of the top ring 21. The ring opening wall of the top ring 21 is stepped. The PCB board 1 is embedded in the ring opening, with the peripheral wall abutting against the ring cavity wall, and the stepped surface abutting and supporting the PCB board.
[0027] In this example, the top ring 21 is composed of multiple parts, such as arc-shaped rods, and multiple parts 26 are distributed in a ring shape along the circumferential direction. The gap between the left and right adjacent parts corresponds to the slot 10, which is convenient for the wire end to enter. The connecting arms can correspond to the parts one by one, or one part can be connected to multiple connecting arms at the same time.
[0028] In this example, a through hole, namely a mounting hole 25, is formed in the axial direction on the bottom ring 23, and a screw is connected to the mounting hole. When the bottom ring abuts against the end face of the frame, the screw is screwed into the mounting hole to fix it.
[0029] The bracket is an integrated structure.
[0030] like Figure 2 As shown, for the card slot, the card slot 10 can be formed at intervals at the ring wall and the peripheral wall of the PCB board 1, and the card slot can be L-shaped, and the welding point 11 can be formed near the card slot.
[0031] During installation, the PCB board is fixed on the bracket, the bottom ring of the bracket is abutted against the end face of the frame and fixed, the winding wire end is inserted into the slot, and then it can be welded in sequence.
[0032] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments.
