After the fixture is assembled, the USB device and the RJ11 device can be placed in two independent areas, the phenomenon that the fixture cannot be horizontally placed on a welding workbench due to the height difference of the devices is avoided, and the good relative position of the devices is provided, so that a welding operator does not need to manually adjust the fixture for multiple times. The PCB to be welded can be directly placed on the clamp without being held by hands, so that a welding operator can conveniently weld.

Description

Be used for manual welded auxiliary fixture of signal converter

Technical Field

The utility model relates to a clamp, in particular to an auxiliary clamp for manual welding of a signal converter.

Background

During the manufacture of the signal converter, all the components contained in the product need to be soldered to the PCB manually. And the relative dimensions between the component and the PCB are measured after soldering is completed.

Currently, the conventional manual soldering method is to solder the USB device with a low height first, and then solder the RJ11 device with a high height. Disadvantages of the current welding process are: because the size of the bonding pad of the PCB is slightly larger than that of the soldering leg of the device, the relative position between the devices cannot be completely ensured manually, the two devices cannot be kept isolated, and the risk of product failure caused by electrical communication exists. Meanwhile, as the USB device is provided with the curled edge, the USB device cannot be completely attached to the welding workbench, so that the welded USB device is not completely perpendicular to the PCB, a product cannot be installed in a pre-designed shell, multiple times of manual adjustment are needed, and the risk of damaging a bonding pad and increasing the rejection rate is caused.

Disclosure of Invention

In view of the above-mentioned drawbacks or shortcomings of the prior art, it is desirable to provide an auxiliary fixture for manual welding of signal converters, which is developed for solving the problem that components cannot be laid flat on a welding table due to inconsistent heights of the components, and the welding process is inconvenient to perform.

According to the technical proposal provided by the embodiment of the application, the auxiliary fixture for manual welding of the signal converter comprises a guard plate I and a guard plate II,

the rear limiting plate is fixed between the first guard plate and the second guard plate through glue,

the middle parts of the first guard plate and the second guard plate are provided with height adjusting cushion blocks, and the front ends of the height adjusting cushion blocks are fixed with a front limiting plate through glue;

the other end of the height adjusting cushion block is inserted with a movable insulating partition plate.

In the utility model, a guide groove is formed between the height adjusting cushion block and the front limiting plate.

In the utility model, the first guard plate and the second guard plate are thick in one part and thin in the other part, and the thick part is twice as thick as the thin part.

In the utility model, the installation directions of the first guard plate and the second guard plate are opposite.

To sum up, the beneficial effects of this application: convenient to use, easy to operate. After the fixture is assembled, the USB device and the RJ11 device can be placed in two independent areas, the phenomenon that the fixture cannot be horizontally placed on a welding workbench due to the height difference of the devices is avoided, and the good relative position of the devices is provided, so that a welding operator does not need to manually adjust the fixture for multiple times. The PCB to be welded can be directly placed on the clamp without being held by hands, so that a welding operator can conveniently weld.

Detailed Description

The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, an auxiliary fixture for manual welding of signal transducers comprises the following components;

and the first guard board 1 is used for attaching the USB and RJ11 devices to the left side and limiting the positions of the devices, and simultaneously supporting the PCB substrate to be welded.

One guard plate II 2: the device is used for attaching the right side of the USB and RJ11 device and limiting the device position, and simultaneously supporting the PCB substrate to be welded.

An insulating spacer 6: the device is used for insulating and isolating USB and RJ11 devices, and preventing the devices from being conducted due to displacement.

A height adjustment spacer 4: the device is used for eliminating the height difference between the USB device and the RJ11 device, so that the USB device is just supported, and the device is ensured to be perpendicular to the welding surface.

A front limiting plate 5: the USB device is arranged on the height adjusting cushion block and used for fixing the position of the USB device, and the grooving on the USB device can accommodate the curled edge of the USB device.

A rear limiting plate 3: for engaging the rear side of the RJ11 device and limiting the device position.

And combining the first guard plate 1, the second guard plate 2 and the rear limiting plate 3, ensuring the edge alignment and fixing by glue.

The height adjusting cushion block 4 is inserted into the combined guard board, fixed by glue, and whether the lower surface is horizontal or not is checked.

The front limiting plate 5 is mounted on the height adjusting spacer 4, fixed with glue, and the guide groove formed after the mounting is checked for accommodating the curled edge of the USB device.

After the height adjustment spacer 4, an insulating spacer 6 is inserted, the component is not fixed, and the proper position is adjusted along with the inserted welding device.

And (5) checking the installation state of each part, and cleaning the glue overflow of the internal joints.

After the fixture is assembled, the USB device and the RJ11 device can be placed in two independent areas, the phenomenon that the fixture cannot be horizontally placed on a welding workbench due to the height difference of the devices is avoided, and the good relative position of the devices is provided, so that a welding operator does not need to manually adjust the fixture for multiple times. The PCB to be welded can be directly placed on the clamp without being held by hands, so that a welding operator can conveniently weld.

In use, as shown in fig. 2, the tool is placed on the plane of a welding table, and the device to be welded is placed. The device was gently rocked to confirm that the device was in place. The insulating spacer 6 will be sandwiched between the two devices to provide an insulating spacing without manual intervention. The PCB may then be placed on the pin face for soldering. And taking out the product after the welding work is finished.

The above description is only illustrative of the preferred embodiments of the present application and of the principles of the technology employed. Meanwhile, the scope of the utility model referred to in this application is not limited to the technical solutions of the specific combination of the above technical features, but also covers other technical solutions formed by any combination of the above technical features or their equivalents without departing from the inventive concept.
