Problems solved by technology

[0004] Although clamping can be realized in this way, each ejector assembly directly drives the pressing assembly to move towards the direction of the product to be welded to achieve clamping. Setting a plurality of such ejector assemblies makes the entire clamp larger in size and poor in compactness.

Embodiment 1

[0038] Embodiment 1: a kind of ultrasonic welding fixture, such as figure 1 and figure 2 As shown, it includes a base 1, a placement part is provided at the center of the base 1, and the placement part is sunken to form a placement groove 2 for the placement of the weldment, and the first workpiece 3 to be welded is placed in the placement groove 2. A second piece to be welded 4 is stacked on a piece to be welded 3, wherein the first piece to be welded 3 and the second piece to be welded 4 are connection terminals, wherein the second piece to be welded 4 is integrally located in the placement groove 2, the first Part of the part to be welded 3 is located in the placement groove 2, and part of it is bent upwards and higher than the placement groove 2 to form a bent part 5. A through groove 6 is opened on the bent part 5. At the same time, a support for the bent part 5 is provided on the base 1. Support block 7, the first workpiece 3 to be welded is pre-positioned by the suppo...

Embodiment 2

[0044] Embodiment 2: a kind of ultrasonic welding fixture, such as Figure 4 As shown, its difference from Embodiment 1 is that only one slide block 11 is provided in the chute 13, and the auxiliary clamp block 17 and the protrusion 16 on the clamp block 10 are all slidably connected to the slide block 11 at the same time. In a chute 15, only a single driver 12 can be set at one end of the chute 13 to drive the slider 11 to move, and realize the synchronous movement of the auxiliary clamping block 17 and the clamping block 10 to realize clamping or loosening. Open, the structure is more simplified, and the number of driving parts 12 is reduced, effectively reducing the cost.

Embodiment 3

[0045] Embodiment 3: a kind of ultrasonic welding fixture, such as Figure 5 As shown, the difference between it and Embodiment 1 lies in the difference in the structure of the linkage. In this embodiment, the linkage includes a linkage bar 21, and the two ends of the linkage bar 21 are respectively hinged on the slider 11, the clamping block 10, the slider 11 and the auxiliary clamping block 17, the force is directly transmitted to the clamping block 10 and the auxiliary clamping block 17 through the linkage bar 21 to drive them to move synchronously, and the direct linkage between the slider 11 and the clamping block 10 can also be realized. The overall structure of the linkage is simpler; and when the clamping block 10 and the auxiliary clamping block 17 are in the clamped state, the linkage bar 21 is perpendicular to the sliding direction of the slider 11, and at this time, there will be no separation even if the subsequent vibration generated by welding The force drives t...

Abstract

The invention discloses an ultrasonic welding clamp. The ultrasonic welding clamp comprises a base, wherein a placing part for placing a piece to be welded is arranged on the base; the edge part of the placing part is connected with a clamping block in a sliding mode; sliding blocks are arranged on the base in a sliding mode; the sliding directions of each sliding block and the clamping block areperpendicular to each other; a linkage piece is arranged between each sliding block and the clamping block; and driving pieces for driving the sliding blocks to move are arranged on the base. Each sliding block is driven to move by the corresponding driving piece and the clamping block is linked by each linkage piece to clamp the piece to be welded, and the sliding directions of each sliding blockand the clamping block are perpendicular to each other, so that the whole length of the clamp in the sliding direction of each sliding block is shorter, each driving piece is more compact on the clamp, and the size of a whole mould is smaller; and in addition, high-frequency vibration can exist in ultrasonic welding, and the clamping block cannot be directly transmitted to each driving piece dueto vibration, so that the purpose of better clamping stability is achieved, and the whole welding precision is higher.

Description

technical field [0001] The invention relates to the field of fixtures, more specifically, it relates to an ultrasonic welding fixture. Background technique [0002] Ultrasonic welding is the use of high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form fusion between molecular layers. It can be used for welding plastic products. It can also be applied to the welding of metal products. [0003] For example, the Chinese patent with the notification number CN208696544U discloses an ultrasonic welding fixture, which includes a fixed base and at least three pressing components evenly arranged on the fixed base. The tight component is arranged on the outside of the fixed base along the circumferential direction of the fixed plate. The product to be welded is placed on the fixed plate, and the fixed component is arranged on the fixed base to resist the product to ...
