Description

Technical Field

[0001] The utility model relates to the technical field of capacitive pen welding, and particularly relates to a positioning device for capacitive pen welding. Background Technique

[0002] A capacitive pen is a pen made of a conductor material with conductive properties, used to touch a capacitive screen to complete human-computer interaction operations. The capacitive pen is an auxiliary device that uses a conductor material to imitate the human body (usually a finger) to complete human-computer interaction.

[0003] For the existing Chinese utility model patent with the reference publication number: CN203418278U, it discloses a welding positioning device. The device includes a bottom plate. At one end of the surface of the bottom plate, two workpiece brackets are symmetrically arranged. Between the two workpiece brackets, a limiting plate is symmetrically arranged. On the surface of the limiting plate, a connecting rod pressing mechanism is arranged. On the surface of the end of the bottom plate where no workpiece bracket is arranged, a positioning block is arranged. A hole is opened on the positioning block, and a groove is also opened on the positioning block. Compared with the prior art, through the positioning in three directions of the workpiece bracket, the limiting plate and the positioning block, the processed workpiece is accurately positioned. Then, through the groove opened on the positioning block, the welding part and the processed workpiece are positioned, ensuring the accuracy and symmetry of welding.

[0004] The existing positioning device generally restricts the position of the workpiece through a fixture. Since the outer shape of the capacitive pen is cylindrical, a large clamping force is required in this way to restrict the position of the capacitive pen, which may cause damage to the appearance of the capacitive pen. And affected by the outer shape of the capacitive pen, this method requires manual restriction of the position of the capacitive pen before clamping to avoid the movement of the capacitive pen, which is very inconvenient.

[0015] Compared with the prior art, the utility model provides a positioning device for the welding of a capacitive pen, which has the following beneficial effects:

[0016] 1. Through the setting of the bracket in the utility model, the bracket is fixedly installed at the center of the top surface of the bottom plate. The top end of the bracket is an arc surface structure. After the pen barrel is placed above the bracket, the pen barrel will roll to the center of the bracket under the influence of its own gravity and the arc surface structure at the top end of the bracket. A groove for fitting with the magnetic strip is arranged at the center of the arc surface structure of the bracket, and the magnetic strip is fitted and installed in the groove structure of the bracket. After the pen barrel rolls to the center of the top end of the bracket, the magnetic force of the magnetic strip will adsorb the pen barrel to the center of the bracket.

The lower part of the guiding columns is fixedly connected to the bottom plate. The silica gel pads are symmetrically installed on the left and right sides of the front end of the clamp. The spring is located between the limiting plate and the clamp. When the limiting pistons on both sides of the bottom plate extend, the distance between the clamps is reduced, so that the silica gel pads at the front end of the clamps contact the pen barrel. The silica gel pads will generate deformation for fitting with the pen barrel along with the extension of the limiting pistons to facilitate fixing the position of the pen barrel and play a protective role for the pen barrel at the same time. At the same time, as the limiting pistons extend, the limiting plate will squeeze the spring, making the spring in a contracted state. The spring clamps the pen barrel by the elastic force during contraction. This method can avoid excessive pressure on the surface of the pen barrel and cause deformation.

The limiting columns 17 are symmetrically installed on the left and right sides of the limiting plate 16 with the center of the limiting plate 16 as the reference, and a sliding connection is formed between the limiting columns 17 and the limiting plate 16. The clamp 19 is movably connected to the limiting plate 16 through the limiting columns 17. A concave structure for fitting with the bracket 11 is provided on the front side of the clamp 19.

[0028] Specifically, the base plate 1 can play a supporting role. The bracket 11 can limit the position of the pen barrel.

[0029] In use, the bracket 11 is fixedly installed at the center of the top surface of the bottom plate 1. The top end of the bracket 11 is an arc surface structure. After the pen barrel is placed above the bracket 11, the pen barrel will roll to the center of the bracket 11 under the influence of its own gravity and the arc surface structure at the top end of the bracket 11. A groove for fitting with the magnetic strip 12 is provided at the center of the arc surface structure of the bracket 11.

The spring 18 is located between the limit plate 16 and the clamp 19. When the limit pistons 14 on both sides of the bottom plate 1 extend, the distance between the clamps 19 is reduced, so that the silica gel pads 111 at the front end of the clamp 19 contact the pen barrel. The silica gel pads 111 will deform to fit with the pen barrel as the limit pistons 14 extend to facilitate fixing the position of the pen barrel and at the same time protect the pen barrel. At the same time, as the limit pistons 14 extend, the limit plate 16 will squeeze the spring 18, making the spring 18 in a contracted state. The clamp 19 clamps the pen barrel by the elastic force of the spring 18 during contraction. This method can avoid excessive pressure on the surface of the pen barrel and cause deformation.
