[0029] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0030] In order to solve the problem of increasing the labor intensity of workers and poor locking precision of the power line terminal row and the board card in the related art, the present application provides a positioning tool.
[0031] As Figures 1 to 7As shown, the positioning tool includes a base 10, a fixing assembly 20, and a positioning assembly 40. The base 10 has a board mounting area 11, the fixing assembly 20 includes a fixing structure 21 for fixing a board 30 mounted in the board mounting area 11. The positioning assembly 40 includes a matching structure 41 and a positioning structure 42, the matching structure 41 is arranged on the base 10 and has a first matching part 411, the positioning structure 42 is movably arranged on the base 10 and includes a crimping part 421 and a second matching part 422. The positioning assembly 40 has a non-positioning state in which the first matching part 411 is separated from the second matching part 422, and a positioning state in which the positioning structure 42 moves to the first matching part 411 and the second matching part 422 are limited to stop. When the positioning assembly 40 is in the positioning state, the crimping part 421 presses the power line terminal 80 on the board 30.
[0032] The technical scheme of the embodiment can quickly and accurately press the power line terminal 80 on the board 30 when the positioning assembly 40 is in the positioning state, thereby reducing the time for manual adjustment and improving the efficiency of production and assembly. Thus, the automatic positioning function of the positioning tool reduces the dependence on manual positioning, and one worker can complete the fixing work of the power line terminal 80 and the board 30, thereby reducing labor costs and solving the problem of poor locking precision and increased labor intensity of workers in related technologies.
[0033] Alternatively, one of the first matching part 411 and the second matching part 422 is a protrusion, and the other is a recess, and the protrusion extends into the recess to limit the stop. In this way, the positioning structure 42 can be accurately fixed at a specific position by the cooperation of the protrusion and the recess. The above cooperation ensures that the crimping part 421 can accurately apply pressure between the power line terminal and the board in the locked state, thereby improving the positioning accuracy of the entire tool system. At the same time, after the protrusion extends into the recess, the cooperation of the two forms a physical stop, effectively preventing the positioning structure 42 from shaking or accidentally moving during locking, thereby enhancing the stability of the entire system and making the operation more reliable and less likely to fail or deviate due to the movement of the positioning structure.
[0034] In the embodiment, the second matching part 422 is a protrusion, and the first matching part 411 is a recess, and the protrusion extends into the recess to limit the stop, so that the positioning assembly 40 is in the positioning state, and the power line terminal is pressed on the board 30 by the crimping part 421, thereby facilitating subsequent locking of the power line terminal on the board 30.
[0035] In other embodiments not shown in the drawings, the second fitting part is a recess, the first fitting part is a protrusion, the protrusion extends into the recess to limit the stop, so that the positioning assembly is in the positioning state, and the power line terminal is pressed on the board card through the pressure joint part, and then the power line terminal is locked on the board card.
[0036] As shown in Figure 3 The positioning structure 42 includes a first plate body 423, a second plate body, and a third plate body 424. The second plate body is arranged on the first side edge of the first plate body 423 to form a pressure joint part 421. The third plate body 424 is arranged on the second side edge of the first plate body 423, and the second fitting part 422 is arranged on the plate surface of the third plate body 424; the second side edge is connected with the first side edge and is arranged at an angle. Among them, the third plate body 424 is two, and the two third plate bodies 424 are oppositely arranged; the second fitting part 422 is two, and the two second fitting parts 422 are arranged one by one corresponding to the two third plate bodies 424. In this way, by forming the pressure joint part 421 through the second plate body and the first side edge of the first plate body 423, and arranging the third plate body 424 on the second side edge of the first plate body 423, the power line terminal can be positioned and pressed from multiple angles. The above-mentioned multi-angle contact and pressure distribution ensures the stability and firmness of the terminal during the locking process, and avoids the position deviation or damage caused by single-point stress. At the same time, the above-mentioned arrangement of the third plate body 424 forms a triangular stability structure, which enhances the overall structural strength, so that the positioning structure 42 is not easy to deform or damage when bearing pressure, and ensures the stability and durability of long-term use.
[0037] In this embodiment, the second side edge is connected with the first side edge and is arranged at an angle, which makes the positioning structure 42 more in line with the ergonomic principle during operation, and facilitates the operator to push the positioning structure 42 with a natural gesture, reduces the fatigue during operation, and improves the work efficiency.
[0038] As shown in Figure 4 The fitting structure 41 includes a mounting block 412 and a fourth plate body 413. Among them, the mounting block 412 is connected with the machine base 10, and the fourth plate body 413 is arranged on the side edge of the mounting block 412. The fourth plate body 413 has an opening arranged away from the mounting block 412, and the opening forms the first fitting part 411. In this way, the connection of the mounting block 412 with the machine base 10 ensures the stability of the fitting structure 41, avoids arbitrary movement during the locking screw operation, and guarantees the accuracy and consistency of positioning each time. At the same time, the opening on the fourth plate body 413 as the first fitting part 411 cooperates with the second fitting part 422 on the positioning structure 42. When the positioning structure 42 moves into position, the second fitting part 422 will extend into the opening of the fourth plate body 413, forming a mechanical limit to prevent further movement of the positioning structure 42, ensuring the accuracy of positioning and the smooth progress of the locking screw operation.
[0039] As shown in Figure 1 The positioning structure 42 is slidably arranged on the base 10; the base 10 is provided with a guide column 12, and the third plate body 424 is provided with a sliding groove 4241 penetrating through the plate face of the third plate body 424; at least part of the guide column 12 extends into the sliding groove 4241 to slide along the extension direction of the sliding groove 4241; the extension direction of the sliding groove 4241 is consistent with the sliding direction of the positioning structure 42. In this way, the guide column 12 extends into the sliding groove 4241 of the third plate body 424, so that the positioning structure 42 slides along the axial direction of the guide column 12, and this guiding mechanism ensures the accurate movement path of the positioning structure 42, can accurately align the power line terminals on the board, and improves the positioning accuracy and success rate of the screw locking operation. At the same time, the setting of the sliding groove 4241 makes the movement of the positioning structure 42 more smooth, reduces the friction and resistance in the movement process, so that the operator can quickly and easily move the positioning structure 42 to the locking position, and improves the operation efficiency and convenience.
[0040] As shown in Figure 1 The base 10 is provided with a mounting hole, and the positioning tool further comprises a positioning column 50, the positioning column 50 comprising a first column body and a head arranged on one end of the first column body, the first column body being detachably mounted in the mounting hole; when the first column body is mounted in the mounting hole, the board 30 is located between the base 10 and the head to limit and stop the board 30 by the head. The outer diameter of the head is larger than the outer diameter of the first column body. In this way, after the first column body of the positioning column 50 is mounted in the mounting hole, the board 30 will be placed between the base 10 and the head of the positioning column, and the limiting and stopping effect of the head can accurately fix the board 30, ensuring that it will not move when locking the power line terminal row, and improving the positioning accuracy and fixing effect of the screw locking operation. At the same time, the diameter of the head is larger than the diameter of the first column body, which means that the head has a larger contact area with the board 30, can provide stronger support force and more stable fixing effect, thereby reducing the local stress of the board 30, avoiding the damage risk of the board under strong pressure, and enhancing the reliability of the entire positioning tool system.
[0041] As shown in Figure 1As shown, the fixing assembly 20 also includes a rotating structure 22, which is rotatably mounted on the base 10. The rotating structure 22 includes an extension arm, and the fixing structure 21 is mounted on the extension arm. The fixing assembly 20 has two configurations: the rotating structure 22 rotates to a fixed position above the board mounting area 11, and the rotating structure 22 rotates to a retracted position where the fixing structure 21 avoids the board mounting area 11. When the fixing assembly 20 is in the fixed position and the board 30 is within the board mounting area 11, the fixing structure 21 presses the board 30 into the board mounting area 11. The rotatable nature of the rotating structure 22 allows the fixing structure 21 to flexibly rotate from a fixed position above the board mounting area 11 to a retracted position where the board 30 is removed. This not only facilitates the installation and removal of the board 30, but also enables the fixing assembly 20 to adapt to different operating scenarios or the positioning requirements of boards of different sizes, thereby improving the versatility of the tooling and the ease of operation.
[0042] In this embodiment, during the installation of the board 30, the fixing structure 21 can be initially positioned in a retracted position, allowing the operator to conveniently place the board within the board installation area 11. Once the board 30 is positioned, the fixing structure 21 rotates to the fixed position, tightening the board 30. This reduces operator waiting time during the operation and improves the continuity and efficiency of the screw tightening operation.
[0043] like Figure 6 As shown, the fixed structure 21 includes a second column 211 and a pressure block 212, and the second column 211 is connected to the extension arm. The pressure block 212 is arranged at the end of the second column 211 to press the board 30. The pressure block 212 is made of rubber or silicone; or, the pressing surface of the pressure block 212 is made of rubber or silicone. In this way, the pressure block 212 or its pressing surface made of rubber or silicone can effectively disperse the pressure when pressing the board 30, avoiding local excessive pressure from causing damage to the board and its sensitive components. The above-mentioned material, due to its high elasticity and softness, can fit well on the surface of the board, reduce indentations and wear, and ensure the integrity of the board and the stability of the circuit.
[0044] In this embodiment, the high friction coefficient of the rubber or silicone material enables the clamp 212 to provide greater friction when pressing the board 30, effectively preventing the board from slipping or shifting during the screw tightening process, ensuring the accuracy and stability of the screw tightening operation. Furthermore, the resilience of these materials helps prevent the board from bouncing or causing unnecessary displacement when the clamp is removed, ensuring a smooth and safe operation.
[0045] Optionally, the board mounting area 11 is a groove, with the mounting hole located within the groove; and / or, the positioning structure 42 further includes a handle 425 disposed on the first plate 423. Thus, designing the board mounting area 11 as a groove provides a natural positioning reference for the board 30. The edge of the board 30 can be accurately aligned with the sidewalls of the groove, thereby ensuring the precise positioning and stability of the board during installation, avoiding slight movement or deflection, and ensuring precise alignment of the power cord terminal block with the board. Furthermore, the groove design can more effectively utilize the space in the base 10, reducing the space occupied by the board mounting area 11, leaving more room for other components and the operator's hands, optimizing the working environment, and improving the convenience and safety of operation.
[0046] In this embodiment, the board mounting area 11 is a recessed groove, with the mounting holes located within it. The positioning structure 42 also includes a handle 425 disposed on the first plate 423. This design prevents operators from directly contacting other parts of the positioning structure 42, particularly components that may have sharp edges or be easily damaged during operation. This not only protects the operator's hands but also reduces the risk of damage to the positioning structure 42 due to incorrect operation.
[0047] like Figure 2 and Figure 7 As shown, the positioning tool also includes a box 60 and a magnet 70. Among them, the magnet 70 is arranged on the bottom surface of the machine base 10, and the machine base 10 is magnetically attracted to the box 60 through the magnet 70. In this way, the magnetic attraction between the magnet 70 and the box 60 provides a stable working platform for the positioning tool to ensure that the positioning tool will not be displaced by external force or vibration during the screw locking operation, thereby improving the accuracy and stability of the operation. At the same time, the magnetic attraction connection method makes the deployment and movement of the positioning tool extremely fast and simple. The operator can stabilize the tool on the box 60 without complicated fixing tools. When it is necessary to change the working position or adjust the layout, the positioning tool can be easily separated to achieve fast and flexible movement, thereby improving production efficiency and operational flexibility.
[0048] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0049] When the positioning assembly is in the positioning state, the crimping section can quickly and accurately press the power cord terminal onto the board, thereby reducing the time required for manual positioning and improving production and assembly efficiency. In this way, the automatic positioning function of the positioning tool reduces reliance on manual positioning, allowing a single worker to complete the task of securing the power cord terminal to the board, reducing labor costs and resolving the problem in related technologies of increasing the labor intensity and poor locking accuracy of the power cord terminal block and board.
[0050] The principles and implementations of the present application are described in detail with specific examples in this paper, and the above examples are only used to help understand the method and its core idea of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, some improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
