Description

Technical Field

[0001] This utility model relates to the technical field of PCA assembly fixtures, and in particular to a fixture that can check the dispensing height of circuit boards and the length of cables. Background Technology

[0002] Because the customer's circuit board design includes cables that require hand soldering, hot melt adhesive is needed to fix them in place to ensure the strength of the solder joints. Therefore, it is also necessary to control the overall height of the product after adhesive application. Current technology uses separate fixtures for cable length inspection and adhesive application height inspection. In actual operation, it is necessary to switch between two different fixtures for inspection, which wastes time due to repeated handling and transportation. Furthermore, the detection of adhesive application height is inaccurate due to cable movement. Therefore, it is necessary to design an auxiliary fixture that can simultaneously check the adhesive application height and cable length on the circuit board. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a fixture that can check the dispensing height and cable length of circuit boards. The fixture uses a cavity to accurately position and place the PCBA, and uses a linear guide rail and a limit slider to precisely control the dispensing height. The two-in-one integrated design reduces the number of fixtures, optimizes fixture management, reduces waste caused by handling during fixture switching, improves production efficiency, and enhances inspection accuracy.

[0004] The technical solution adopted by this utility model is a fixture that can realize the inspection of the dispensing height of circuit boards and the length of cables. It includes: a fixture body, a cavity set on the fixture body for placing the circuit board, a positioning mechanism for holding one end of the cable, and a measuring mechanism for measuring the dispensing height of the cable and the circuit board. The measuring mechanism includes a linear guide rail set on the side of the cavity and a limiting block slidably set on the linear guide rail. The limiting block can be moved to the dispensing point to detect whether the dispensing height is qualified.

[0005] In a preferred embodiment of the present invention, the linear guide rail is disposed on the outside of the cavity and is arranged parallel to the cavity.

[0006] In a preferred embodiment of this invention, the length of the linear guide rail is greater than the length of the cavity.

[0007] In a preferred embodiment of this utility model, a scale is provided on the clamp body along the unfolding direction of the cable.

[0008] In a preferred embodiment of this utility model, the scale is provided with a shortest limit line and a longest limit line.

[0009] In a preferred embodiment of the present invention, the positioning mechanism is disposed on the side of the clamp body away from the cavity.

[0010] In a preferred embodiment of the present invention, the positioning mechanism is a positioning ring disposed on the clamp body, and the positioning ring has a notch into which the cable can be inserted.

[0011] The beneficial effects of this utility model are: the fixture accurately positions and places the PCBA shape by relying on the cavity, and accurately controls the dispensing height by relying on the linear guide rail and the limit slider. The two-in-one integrated design reduces the number of fixtures, optimizes fixture management, reduces the waste of picking and placing and handling caused during fixture switching, improves production efficiency, and improves the accuracy of inspection.

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figure 1 The present invention is an embodiment of a fixture for checking the dispensing height of a circuit board and the length of a cable, comprising: a fixture body 1, a cavity 2 disposed on the fixture body for placing the circuit board, a positioning mechanism 3 for holding one end of a cable, and a measuring mechanism for measuring the dispensing height of the cable and the circuit board. The measuring mechanism includes a linear guide rail 4 disposed on the side of the circuit board and a limiting block 5 slidably disposed on the linear guide rail. The limiting block can be moved to the dispensing point to detect whether the dispensing height is qualified.

[0016] Specifically, the linear guide rail is set outside the cavity and parallel to it. The length of the linear guide rail is greater than the length of the cavity. When glue dispensing is required, the circuit board is placed inside the cavity, one end of the cable is aligned with the glue dispensing point on the circuit board, and the other end is held in place by a positioning mechanism. The positioning mechanism is set on the side of the fixture body away from the cavity. The positioning mechanism is a positioning ring set on the fixture body. The positioning ring has a notch that can hold the cable. The other end of the cable is inserted into the notch of the positioning ring, and then the glue dispensing operation is performed. After the glue dispensing is completed, the thickness of the limiting block is adjusted according to the upper limit height of the glue dispensing required by the customer as a reference. When the glue dispensing height exceeds the required height, the limiting block cannot pass through when it slides past the glue dispensing point, which can effectively screen out defective products.

[0017] Specifically, a scale 6 is provided on the clamp body along the unfolding direction of the cable. The scale is provided with a shortest limit line 61 and a longest limit line 62. The cable length is within the two limit lines and is considered good. The clamp of this utility model can simultaneously detect the dispensing height and the cable length. The two-in-one design reduces the number of clamps and reduces the waste caused by picking and handling during clamp switching.

[0018] The beneficial effects of this utility model of a fixture that can check the dispensing height of circuit boards and the length of cables are:

[0019] 1. The fixture uses the cavity to precisely position and place the PCBA shape, and uses linear guides and limit sliders to precisely control the dispensing height;

[0020] 2. The integrated design of the two-in-one fixtures reduces the number of fixtures, optimizes fixture management, reduces waste caused by handling and loading during fixture switching, improves production efficiency, and enhances the accuracy of inspection.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
