Description

Technical Field

[0001] This application relates to the field of connector manufacturing technology, and more particularly to a fixture and production line. Background Technology

[0002] In related fields, gripper cylinders are used to clamp terminal pins (metal components in connectors used for conductivity and signal transmission). However, when the clamping lever arm is long, the clamping force at the far end is very small and cannot effectively clamp the product. Utility Model Content

[0003] This application provides a fixture and production line to at least partially solve the above-mentioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, a clamp is provided, including a support, a first clamping arm, a second clamping arm, a linkage mechanism, and a linear drive mechanism. The support has a first sliding groove, the second clamping arm is connected to the support, and the linear drive mechanism is connected to the linkage mechanism. The first clamping arm includes a first driving end and a first clamping end. The first driving end has a first sliding portion, which is slidably disposed within the first sliding groove. The first driving end is hinged to the linkage mechanism, and the first clamping end is hinged to the second clamping arm.

[0005] According to a second aspect of this application, a production line is provided, including the fixture described above.

[0006] The clamp of this application embodiment replaces the prior art solution of using a gripper cylinder to hold the PIN needle. It uses a linear drive mechanism to drive the linkage mechanism to move, thereby causing the first clamping arm and the second clamping arm to move closer or further away to clamp or release the PIN needle. The lever-type clamp directly transmits the clamping force, avoiding the loss of clamping force when the clamping lever arm is long, and the appropriate lever arm can be set as needed to amplify the clamping force.

Detailed Implementation

[0012] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0013] In this field, gripper cylinders are commonly used to clamp terminal pins. However, when the lever arm used for clamping is long, the clamping force at the distal end becomes very weak, resulting in ineffective product clamping. This is particularly prominent in certain applications, such as clamping pins in confined spaces. Due to the large size of the cylinder itself, long grippers are often designed to accommodate space constraints. This leads to insufficient clamping force being applied to the distal end of the gripper during clamping, affecting the clamping effect and operational stability. This design limitation not only affects the practical application of gripper cylinders but can also lead to product clamping failure. Therefore, to solve this problem, the gripper design must be improved, or new technologies must be adopted to ensure sufficient clamping force can be applied within limited space, thereby improving the reliability and efficiency of the equipment.

[0014] In view of this, please refer to Figures 1 to 3 This application provides a clamp designed to overcome at least one of the aforementioned technical problems.

[0015] Please see Figure 1 , Figure 2 The clamp includes a support 1, a first clamping arm 2, a second clamping arm 3, a linkage mechanism 4, and a linear drive mechanism 5. Please refer to [link / reference needed]. Figure 4 The support 1 has a first sliding groove 11, and the second clamping arm 3 is connected to the support 1. The linear drive mechanism 5 is connected to the linkage mechanism 4. The linear drive mechanism 5 can be selected from common drive mechanisms such as cylinders, hydraulic cylinders, linear motors, and lead screw and nut pairs. The first clamping arm 2 includes a first driving end 21 and a first clamping end 22. The first driving end 21 is provided with a first sliding part 211, which is slidably disposed in the first sliding groove 11. The first driving end 21 is hinged to the linkage mechanism 4, and the first clamping end 22 is hinged to the second clamping arm 3.

[0016] Please see Figure 3 The linear drive mechanism 5 drives the linkage mechanism 4 to move, thereby driving the first drive end 21 on the first clamping arm 2 to move. Since the first sliding part 211 on the first clamping arm 2 is restricted within the first slide groove 11, the first drive end 21 rotates in a preset direction, that is, it rotates along the first slide groove 11. Since the first clamping end 22 of the first clamping arm 2 is hinged to the second clamping arm 3, the first clamping end 22 will rotate around the hinge position, thereby moving the first clamping end 22 closer to or away from the second clamping arm 3, completing the action of clamping or releasing the PIN needle. The linkage mechanism 4 can be a single link or multiple links, as long as it can drive the first drive end 21 to rotate.

[0017] The clamp in this embodiment replaces the traditional solution of using a gripper cylinder to hold the PIN needle in the prior art. Using a lever-type first clamping arm 2 and second clamping arm 3 to hold the PIN needle effectively avoids the problem of clamping force loss caused by a long lever arm in the prior art, and allows for the setting of an appropriate lever arm to amplify the clamping force as needed. Furthermore, during the design phase, the first clamping arm 2 and second clamping arm 3 can be designed to be relatively slender according to actual needs, making them well-suited for clamping PIN needles in confined spaces.

[0018] Please see Figure 1 , Figure 3 In some embodiments, the second clamping arm 3 includes a second driving end 31 and a second clamping end 32. The second driving end 31 is provided with a second sliding portion 311 and is hinged to the linkage mechanism 4. The second clamping end 32 is hinged to the first clamping end 22. Please refer to [link to relevant documentation]. Figure 4 The support 1 also has a second sliding groove 12, and the second sliding part 311 is slidably disposed in the second sliding groove 12. The movement mode of the second clamping arm 3 is similar to that of the first clamping arm 2, and will not be described again. In this embodiment, both the second clamping arm 3 and the first clamping arm 2 are hinged to the linkage mechanism 4. Under the drive of the linkage mechanism 4, the first clamping end 22 and the second clamping end 32 move closer or further away from each other to achieve the action of clamping or releasing the PIN needle. The linkage mechanism 4 can drive the first driving end 21 and the second driving end 31 to move further or closer to each other. Compared with the solution where the second clamping arm 3 is stationary, the simultaneous movement of the first clamping arm 2 and the second clamping arm 3 can better clamp the PIN needle.

[0019] Please see Figure 1 , Figure 3 In some embodiments, the linkage mechanism 4 includes a first link 41, a second link 42, and a third link 43. The first link 41 is connected to the linear drive mechanism 5. One end of the second link 42 is hinged to the first drive end 21, and the other end is hinged to the first link 41. One end of the third link 43 is hinged to the second drive end 31, and the other end is hinged to the first link 41. Under the drive of the linear drive mechanism 5, the first link 41 moves linearly along the direction of motion of the linear drive mechanism 5. During the movement towards the linear drive mechanism, the second link 42 and the third link 43, which are connected to the first link 41, drive the first drive end 21 and the second drive end 31 to rotate towards each other, thereby causing the first clamping end 22 and the second clamping end 32 to rotate away from each other, thus realizing the release action. As the first link 41 moves away from the linear motion mechanism, it pushes the first drive end 21 and the second drive end 31 to rotate away from each other through the second link 42 and the third link 43 connected to the first link 41. This causes the first clamping end 22 and the second clamping end 32 to rotate towards each other, thus realizing the clamping action.

[0020] Please see Figure 1 , Figure 3 In some embodiments, the first link 41 has a third slide groove 411, which is arranged along the movement direction of the linear drive mechanism 5. The linkage mechanism 4 also includes a fourth link 44 and a fifth link 45. One end of the fourth link 44 is hinged to the first drive end 21, and the other end is slidably disposed in the second slide groove 12. One end of the fifth link 45 is hinged to the second drive end 31, and the other end is slidably disposed in the second slide groove 12. The fourth link 44 and the fifth link 45 perform corresponding driven actions as the first link 41 and the corresponding first drive end 21 and second drive end 31 move, which can make the rotation process of the entire fixture more stable.

[0021] Please see Figure 1 , Figure 3 In some embodiments, the first sliding part 211 is disposed between the second link 42 and the fourth link 44, and the second sliding part 311 is disposed between the third link 43 and the fifth link 45, so that the distance between the second link 42 and the fourth link 44, and the distance between the third link 43 and the fifth link 45 can be set to be larger, thereby making the movement process of the link structure smoother, and thus making the rotation process of the clamp more stable.

[0022] Please see Figure 1 , Figure 3 In some embodiments, the linkage mechanism 4 further includes a first pin 46, which is slidably disposed within the third slide groove 411 and rotatably connected to the fourth link 44 and / or the fifth link 45. Specifically, the first pin 46 can be fixed to the third link 43 and rotatably connected to the fifth link 45, or fixed to the fifth link 45 and rotatably connected to the third link 43, or rotatably connected to both the third link 43 and the fifth link 45 simultaneously. The first pin 46 allows the third link 43 and the fifth link 45 to be slidably connected to the third slide groove 411 at the same position, enabling the first clamping arm 2 and the second clamping arm 3 to move synchronously.

[0023] Please see Figures 5 to 7In some embodiments, the support 1 further includes a cover plate 13, which has a fourth sliding groove 131. The first pin 46 is slidably disposed in the fourth sliding groove 131. The fourth sliding groove 131 and the third sliding groove 411 are in the same direction, limiting the two ends of the first pin 46 respectively, making the sliding process of the first pin 46 more stable. Optionally, the cover plate 13 also has a first plug portion 132, which is adapted to the gap between the support 1, the first clamping arm 2 and the second clamping arm 3 to prevent foreign objects from entering the gap and affecting the operation of the clamp. Optionally, it also includes a base plate 14, which is disposed on the other side of the support 1 opposite to the cover plate 13, for closing the support 1. Optionally, the base plate 14 also has a second plug portion 141, which is adapted to the gap between the support 1, the first clamping arm 2 and the second clamping arm 3.

[0024] Please see Figure 1 , Figure 3 In some embodiments, the first slide groove 11 and the second slide groove 12 are arc-shaped grooves. The clamp includes a hinge shaft 6, and the first clamping end 22 and / or the second clamping end 32 are rotatably connected to the hinge shaft 6. Specifically, the hinge shaft 6 can be fixed to the first clamping end 22 and rotatably connected to the second clamping end 32, or fixed to the second clamping end 32 and rotatably connected to the first clamping end 22, or rotatably connected to both the first clamping end 22 and the second clamping end 32 simultaneously. The rotation centers of the first sliding part 211 and the second sliding part 311 overlap with the axis of the hinge shaft 6, so that during the rotation of the first clamping arm 2 and the second clamping arm 3, their rotation centers overlap with the axis of the hinge shaft 6, thereby keeping the position of the hinge shaft 6 relative to the support 1 unchanged, and thus making the process of the clamp holding the PIN needle more controllable.

[0025] Please see Figure 4 In some embodiments, the support 1 also has a limiting groove 15, which is configured to abut against the first driving end 21 and the second driving end 31 at a preset clamping position to limit the clamping position, that is, to limit the minimum distance between the first clamping end 22 and the second clamping end 32, so as to prevent the clamping force from being too large and damaging the PIN pin during the clamping process.

[0026] Please see Figure 4In some embodiments, the support 1 further includes a first sliding limiting part 16 and a second sliding limiting part 17. A first driving end 21 is disposed between the first sliding limiting part 16 and the first sliding groove 11. The first sliding limiting part 16 is used to limit the sliding of the first sliding part 211 during its sliding process. A second driving end 31 is disposed between the second sliding limiting part 17 and the second sliding groove 12. The second sliding limiting part 17 is used to limit the sliding of the second sliding part 311 during its sliding process. The first sliding limiting part 16 and the second sliding limiting part 17 are used in conjunction with the first sliding groove 11 and the second sliding groove 12 to limit both ends of the first sliding part 211 and the second sliding part 311, making the rotation process of the first clamping arm 2 and the second clamping arm 3 more stable. The first sliding part 211 and the second sliding part 311 can be selected as a second hinge shaft and a third pin shaft, which can rotatably connect the corresponding first driving end 21 and the second driving end 31, thereby reducing the friction during the sliding process.

[0027] Please see Figure 1 In some embodiments, the linear drive mechanism 5 includes a floating joint 51 connected to the first link 41. The floating joint 51 can absorb the eccentricity angle between the linear drive mechanism 5 and the first link 41, thereby reducing the relative accuracy between the linear drive mechanism 5 and the first link 41.
