Description

Technical field:

[0001] The utility model relates to the technical field of touch module assembly, in particular to a conductive cloth laminating and assembling device in a notebook touch module. Background technology:

[0002] The touch module is one of the important components of a laptop computer. It is mainly used for human-computer interaction of the laptop computer. The touch module is composed of multiple parts, among which the conductive cloth is one of the important components. During the assembly and production process of the touch module, the conductive cloth needs to be attached to the support frame. However, the traditional production method is still mainly manual assembly, which not only has low assembly efficiency and high labor intensity, but is also prone to assembly errors.

[0003] The invention patent application with Chinese patent application number 202010249920.2 discloses a device for pasting conductive cloth and foam. In the technical scheme disclosed in the patent, the conductive cloth is fed by the conductive cloth and foam stripping device 4, and the conductive cloth is grabbed by the manipulator device 5 and pasted on the back shell of the mobile phone. The manipulator device 5 includes an XYZ axial drive component, a conductive cloth suction head component 52 and a foam suction head component 53, and the conductive cloth suction head component 52 includes a lifting drive mechanism 521, a rotating drive mechanism 522 and a hollow suction head 523. During the assembly work, the conductive cloth and foam stripping device 4 places the conductive cloth peeled off on the conductive cloth adsorption seat 417, and then the XYZ axial drive component in the manipulator device 5 moves the conductive cloth suction head component 52 to the conductive cloth adsorption seat 417 to grab the conductive cloth, and then moves the conductive cloth to the industrial camera device 6 to obtain position information, and then moves the conductive cloth to the top of the back shell of the mobile phone to fit the conductive cloth on the conductive cloth assembly position to complete the assembly. In this patent, since a hollow suction head 523 is used to directly absorb the conductive cloth for bonding, and many of the conductive cloth assembly positions in the product are uneven stepped, when the conductive cloth is directly attached by the hollow suction head 523, there will be a situation where the local contact surface cannot be bonded, resulting in an unsatisfactory bonding effect, causing quality problems in the final product, and affecting the yield and lifespan.

[0004] In view of this, the inventor proposes the following technical solution. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a conductive cloth laminating and assembling device in a notebook touch module.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a conductive cloth bonding and assembly device in a notebook touch module, comprising: a material picking robot, on which is at least one material picking claw for grabbing the conductive cloth for assembly, the material picking claw comprising a lifting cylinder, a first pressure plate arranged at the lower end of the lifting cylinder, an active vacuum negative pressure plate floatingly arranged on the first pressure plate and used for adsorbing the conductive cloth, and a second pressure plate floatingly arranged on the first pressure plate; when the lifting cylinder is pressed down, the contact surfaces of the first pressure plate and the active vacuum negative pressure plate and the lower end of the second pressure plate are not at the same height, and after the lifting cylinder is lifted, the contact surface of the lower end of the active vacuum negative pressure plate protrudes from the contact surface of the lower ends of the first pressure plate and the second pressure plate.

[0007] Furthermore, in the above technical solution, one side of the first pressure plate is provided with a first step surface protruding downward and used to press the conductive cloth, and under their own weight, the lower end contact surfaces of the movable vacuum negative pressure plate and the second pressure plate extend out of the first step surface.

[0009] Furthermore, in the above technical solution, the upper end of the movable vacuum negative pressure plate passes through the first pressure plate and is limited by a first limit pin, and the upper end of the second pressure plate passes through the first pressure plate and is limited by a second limit pin.

[0010] Furthermore, in the above technical solution, a positioning cover plate is installed on the upper end of the first pressing plate, and a vacuum pipe joint for connecting the movable vacuum negative pressure plate and the vacuum pipe is provided on the positioning cover plate.

[0011] Furthermore, in the above technical solution, two of the material picking claws are arranged in parallel on the material picking robot, and the two material picking claws are symmetrically distributed; the material picking robot is also provided with two film tearing mechanisms symmetrically located on both sides of the material picking claws, and the film tearing mechanism is used to tear off the protective film on the conductive cloth.

[0012] Furthermore, the above technical solution also includes an assembly line transfer module for transferring semi-finished products, at least one first feeder arranged next to the assembly line transfer module and used to provide conductive cloth, a positioning and cutting mechanism arranged next to the first feeder and used to place and position the conductive cloth, a lower visual inspection module arranged below the movement stroke of the material picking robot and used for secondary positioning of the material placement, and a waste collection device arranged within the movement stroke of the material picking robot and used to collect waste film.

[0014] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model adopts a floating movable vacuum negative pressure plate and a second pressure plate arranged on the lifting cylinder. When the lifting cylinder does not press down, due to the action of gravity, the movable vacuum negative pressure plate and the second pressure plate will sink to the lowest end, so that the movable vacuum negative pressure plate can protrude from the first pressure plate, so that the movable vacuum negative pressure plate can absorb and grab the conductive cloth.

In the automated production process of the touch module, the assembly line transfer module 1 passes through each station in turn, and the assembly equipment at each station places different components into the assembly line transfer module 1 and assembles them. Among them, the conductive cloth laminating process is the next process after the positioning bracket is assembled in the touch module.

A floating movable vacuum negative pressure plate 313 and a second pressing plate 314 are provided on the lifting cylinder 311. When the lifting cylinder 311 does not press down, due to the effect of gravity, the movable vacuum negative pressure plate 313 and the second pressing plate 314 will sink to the lowest end, so that the movable vacuum negative pressure plate 313 can protrude from the first pressing plate 312, so that the movable vacuum negative pressure plate 313 can absorb and grab the conductive cloth.

The first pressing plate 312 will first fit the conductive cloth to the installation position, and then the vacuum negative pressure plate 313 and the second pressing plate 314 will successively fit the conductive cloth to the installation position, so as to achieve step-fitting of the conductive cloth to cope with installation positions on different planes, ensure that the conductive cloth can be completely fitted to the installation position, prevent the conductive cloth from falling off during use, and improve the service life of the finished product.

The movable vacuum negative pressure plate 313 is limited by the positioning cover plate 318 covering the first pressure plate 312 to prevent the vacuum negative pressure plate 313 from extending out from above the first pressure plate 312. Similarly, the second pressure plate 314 is also limited on the first pressure plate 312 in the same way.
