Description

Technical Field

[0001] The utility model relates to the technical field of solder ball production and processing, in particular to a solder ball clamping device. Background Art

[0002] Solder balls are widely used in tinplate, flux, organic synthesis, chemical production, alloy manufacturing, and the assembly of multiple integrated circuits in the electronics industry. They are also used as reagents and reducing agents for the determination of arsenic and phosphate, tin-plated products, etc. After the production process of solder balls is completed, they need to be sampled. Since the solder balls are small, they are usually picked up with tweezers.

[0003] The existing tweezers require certain skills to grip smaller solder balls, and the round structure of the solder balls causes the tweezers to slip easily, so the tweezers need to be clamped with great force to fix the solder balls, which makes the solder balls easily damaged.

[0004] In view of this, we propose a solder ball clamping device that uses a conical three-claw clamp to effectively fit the solder ball and reduce the slippage and damage of the solder ball caused by tweezers clamping. Utility Model Content

[0010] Preferably, the clamping block has a trapezoidal structure, and a groove structure is provided on the inner wall surface of the clamping block. The trapezoidal structure of the clamping block is convenient for fixing solder balls of different sizes, and the groove structure effectively improves the friction force of the inner wall of the clamping block.

[0011] Preferably, the vertical pole includes a main pole and a pull ring, the main pole is connected to the end of the limiting plate, and the pull ring is installed at the end of the main pole, so that an operator can move and fix the vertical pole conveniently through the pull ring.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 - Figure 4 , the utility model provides a technical solution:

[0025] A solder ball clamping device comprises three clamping jaws 1 and a limiting plate 2, wherein the three clamping jaws 1 penetrate the limiting plate 2 together, a vertical rod 4 is arranged on the surface of the limiting plate 2, the vertical rod 4 penetrates a movable tube 3, the clamping jaw 1 comprises a clamping block 11 and an extension rod 12, the clamping block 11 is installed at the end of the extension rod 12, the surface of the extension rod 12 penetrates a connecting pulley shaft 13, both ends of the pulley shaft 13 are slidably connected to the limiting plate 2, the movable tube 3 comprises a fixed disk 32 and a plurality of fixed shafts 34, the plurality of fixed shafts 34 are located at the corners of the fixed disk 32, and the fixed shaft 34 is arranged at the end of the extension rod 12. Since the three clamping jaws 1 can clamp the solder ball, compared with the traditional tweezers clamping, the three clamping jaws 1 can support the solder ball after being combined, so that the clamping jaw 1 is less difficult to operate than the traditional tweezers, and the user can quickly get started, and at the same time, the inner wall of the clamping jaw 1 is also an arc structure, so that the solder ball can be effectively fitted, reducing the squeezing of the solder ball by the clamping jaw 1 during the clamping process.

[0026] The surface of the fixed plate 32 is provided with a tube body 31, and the side of the tube body 31 is provided with a limit bolt 33, and the limit bolt 33 passes through one side of the tube body 31. Through the fixation of the limit bolt 33, the position of the clamping jaw 1 connected to the movable tube 3 cannot be changed, and the clamping jaw 1 can continuously fix the solder ball. The operator does not need to apply external force to keep the clamping jaw 1 fixing the solder ball, which reduces the operator's fatigue and reduces the damage to the solder ball caused by uneven force due to long-term clamping.

[0027] The clamping block 11 has a trapezoidal structure, and a groove structure is provided on the inner wall surface of the clamping block 11. The trapezoidal structure of the clamping block 11 is convenient for fixing solder balls of different sizes, thereby improving the use range of the equipment. At the same time, the groove structure effectively improves the friction force of the inner wall of the clamping block 11, thereby preventing the solder balls from falling off during the clamping process.

[0028] The vertical pole 4 includes a main pole 42 and a pull ring 41. The main pole 42 is connected to the end of the limiting plate 2. The pull ring 41 is installed at the end of the main pole 42. The pull ring 41 facilitates the operator to move and fix the vertical pole 4. A flat cross-section is provided on one side of the main pole 42 to facilitate the fixation between the limiting bolt 33 and the vertical pole 4.

[0029] The surface of the limit plate 2 is provided with rectangular holes for passing the extension rod 12. The extension rod 12 can pass through the hole structure. The rectangular holes can limit the movement range of the extension rod 12 to prevent swinging during extension, stretching or clamping, thereby ensuring the stability of the extension rod 12 during movement.

[0030] The three clamping blocks 11 are combined to form a conical structure. The conical clamping block 11 can effectively fit the solder ball to be clamped, thereby reducing the displacement of the solder ball during the clamping process.

[0031] When the solder ball clamping device of the present invention is in use, it is necessary to loosen the limit bolt 33 on the surface of the tube body 31 so that the tube body 31 can move freely on the surface of the vertical rod 4, the operator inserts the thumb into the pull ring 41, and clamps the tube body 31 with the index finger and the middle finger, and then moves the tube body 31 up and down to test whether the clamping jaw 1 can be used normally, and then the clamping jaw 1 can start to clamp the solder ball. The operator needs to press down the movable tube 3 first so that the fixed plate 32 at the bottom end of the movable tube 3 drives the extension rod 12 to unfold, and the extension rod 12 slides along the groove of the limit plate 2 through the pulley shaft 13. The extension rod 12 makes the solder ball located inside the center of the circle of the clamping jaw 1, and then lifts the tube body 31 so that the extension rod 12 at the bottom end of the tube body 31 is closed, so that the three clamping blocks 11 at the bottom end of the extension rod 12 are connected. The inner wall of the clamping block 11 adopts an arc structure, so that the three clamping blocks 11 are combined with the inner wall to form a conical hollow, so that the solder ball is effectively attached to the inner wall surface of the clamping block 11, thereby fixing the solder ball to be clamped. When long-term clamping is required, the limit bolt 33 on the surface of the movable tube 3 can be tightened, and the limit bolt 33 is pushed inward along the thread, so that the limit bolt 33 squeezes the vertical rod 4 inside the movable tube 3 to generate friction, so that the movable tube 3 is fixed on the surface of the vertical rod 4, and the clamping jaws 1 connected to the movable tube 3 are fixed synchronously, so that the operator of the clamping jaws 1 does not need to apply force continuously, which is convenient for long-term fixation of the solder ball. The inner wall of the clamping block 11 adopts a flexible sponge pad, which will not damage the solder ball during clamping, reducing damage to the surface of the solder ball during clamping.
