Heating bonding clamp

Abstract

The invention relates to a heating bonding clamp which comprises a table face. A bonding structure is arranged on at least one side of the table face. The heating bonding clamp is characterized in that each bonding structure comprises a bearing block, a locating structure, a mounting plate, a pressing block and a heating device; the bearing blocks are fixed to the table face so as to allow the inner surface of the front end face of a fume collection hood to be placed thereon; the locating structures are arranged on the bearing blocks to be used for locating the front end face of the fume collecting hood and face stickers; the mounting plates are fixed to the upper portion of the table face; the pressing blocks are located above the bearing block and are driven by pressing air cylinders mounted on the mounting plates to move up and down; and the heating devices are arranged in the bearing blocks and used for supporting the bearing blocks for heating. Through the arrangement of the heating devices in the bearing blocks, even though in the environment that the temperature is low, initial bonding force of double-face pressure-sensitive adhesive can be ensured, and the problem that theinitial bonding force of the double-face pressure-sensitive adhesive is low to influence reliability due to the low air temperature in winter is solved; and the heating bonding clamp is a bonding toolwhich is reasonable in structural design and can precisely and firmly bond the face stickers to the fume collecting hood, and the heating bonding clamp has the advantages of being high in bonding efficiency and precision, low in number of procedures and convenient to operate.

Description

technical field [0001] The invention relates to a tooling fixture for bonding a certain part to another part, in particular to a bonding fixture for bonding a face sticker to a fume collecting hood. Background technique [0002] The fume collecting hood is the main part of the range hood. It is generally formed by punching and bending thin steel plates and then welded. The fume collecting hood has a top surface with a middle opening. The front end face, left end face and right end face of the front end face, the left end face and the right end face, and the parts where the front end face, left end face and right end face are in contact with each other are fixed together by laser welding, and the front face is the face facing the user, on which control buttons are installed. The range hood uses touch buttons. Due to the structural characteristics of the touch buttons, in order to make the fume collection hood beautiful, it can be bonded and fixed on the front surface.

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly two ways to bond the face stickers to the front face of the smoke collecting hood: one is the traditional bonding, which uses manual bonding of the face stickers to the fan cover. This method has extremely low bonding efficiency. Under the premise of increased cost, the processing cost has increased significantly, and because there is no pressure-holding step, the bonding is not reliable, and the surface sticker is easy to detach from the front face of the smoke collection hood, and the bonding position will be inaccurate due to manual bonding. High technical requirements for workers

[0004] The other is to use simple bonding tooling to bond the face stickers. At present, the simple tooling has the following defects. One is that the size of the bonding is not easy to ensure low accuracy, and the positioning of the smoke collection hood and the face stickers is not accurate. It is easy to dislocate between the fume collecting hood and the face sticker after connecting, and the bonding gap between the fume collecting hood and the face sticker is uneven; the second is that the surface of the fume collecting hood and the face sticker is easily scratched during the bonding process Only one set of fume collecting hoods can be bonded at one time, and the bonding efficiency is low

[0005] Because the face sticker is fixed with the fume collection hood by double-sided pressure-sensitive adhesive, but in the case of low ambient temperature, the initial adhesive force of the double-sided pressure-sensitive adhesive is low, which will affect the adhesion between the face sticker and the fume collection hood.
