Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape bonding, in particular to an automatic adhesive tape assembly bonding device. Background Art

[0002] The bonding of tape components is a major step in the molding process of rubber tape products, and its bonding quality directly affects the subsequent product molding quality. The main bonding material is a flexible tape that is double-sided and unvulcanized. The bonding process requires spraying / coating a bonding solvent on one side of the adhesive tape. After the solvent evaporates, the centers of the two pieces of tape are overlapped and arranged at 45 degrees and bonded together to form a tape component. Figure 1 (Non-porous tape assembly) and Figure 2 (Porous tape assembly). Currently, the adhesive tape assembly bonding process is done manually by operators, which has the following problems:

[0003] 1) Difficulty in locating the bonding position and large angle deviation: The existing bonding method is to simply mark the bonding outer edge position of the small piece of tape on the large piece of tape when cutting the material, and the operator will gradually press the small piece of tape along the mark from one side to the other side to bond. However, in the actual bonding process, the mark will fade after the large piece of tape is sprayed / coated with an adhesion-promoting solvent. During bonding, the operator can only find the edge and control the angle by subjective feeling, which is difficult to achieve precise alignment, which can easily lead to quality problems such as center misalignment and large angle deviation.

[0004] 2) Bubbles are likely to appear between the tape layers after bonding: Under the action of the adhesion-promoting solvent, the surfaces of large and small pieces of tape have strong adhesion. When the operator bonds along one edge in one direction, in order to eliminate the bubbles between the tape layers, the operator generally adopts the method of bonding and pressing at the same time, which requires high standards for the operators. However, even so, due to the manual bonding of flexible tape, bubbles that cannot be eliminated are likely to appear during the process.

[0005] 3) Low bonding efficiency: Due to different techniques of operators, the amount of solvent used is also different, and the waiting time of the process is also different. Not only is the efficiency of manual bonding low, but the quality of the finished product after molding will also be uneven.

[0006] 4) Impact on product molding quality: During the bonding process, operators have manual positioning and angle control deviations, which directly affect the quality consistency of the finished product after molding. Summary of the invention

[0007] In order to solve the problem that the existing adhesive tape assembly bonding performed manually by an operator has large positioning deviation and is prone to bubble generation, the present invention provides an automatic adhesive tape assembly bonding device.

The input of the controller is also connected to the second sensor, and the output of the controller is also used to control the start and stop of the second conveyor belt (it is well known to those skilled in the art that It is known that when the controller judges the position information sent by the second sensor, if it is determined that the small piece of tape has been positioned, the controller controls the second conveyor belt to stop); the base of the automatic pressing station includes a first adsorption plate for adsorbing the large piece of tape, the adsorption plate of the second manipulator is controlled by a plurality of vacuum adsorption chambers to adsorb the small piece of tape, and one side of the adsorption plate of the second manipulator is provided with a driven (this drive can be manual, hydraulic, pneumatic or other) and liftable pressing block (in specific implementation, the bottom of the pressing block is semi-cylindrical, and when the pressing block is pressed down, one end of the small piece of tape is linearly pressed together with the corresponding position of the large piece of tape, thereby increasing the pressing strength and further improving the pressing quality).

[0009] When in use, the process steps are as follows: 1) According to the production arrangement, the cut large piece of tape and the small piece of tape are manually placed on the large piece positioning station and the small piece positioning station respectively; 2) The first conveyor belt and the first U-shaped guide plate are used to cooperate to realize the positioning of the large piece of tape.

Specifically, when the controller determines the positioning of the small piece of tape through the data transmitted by the second sensor, the controller controls the second conveyor belt to stop and wait for the second robot to grab it; 3) The first robot uses vacuum adsorption to move the large piece of tape from the large piece positioning station to the first adsorption plate of the automatic pressing station; 4) The large piece of tape adsorbed on the first adsorption plate is sprayed (can be Manual spraying or external robot or another robot can be added to the device for spraying); 5) The second robot uses vacuum adsorption to take the small piece of tape from the second conveyor belt, and after spraying / coating the adhesion-promoting solvent in the set area according to the process requirements, it moves to the set position of the automatic lamination station; 6) The second robot tilts and moves slowly and gradually, so that one end of the small piece of tape is in linear contact with one end of the set position of the large piece of tape, and the pressing block presses down so that one end of the small piece of tape is pressed together with the corresponding position of the large piece of tape, and the second robot is operated to move forward, so that the pressing block slowly presses the tape assembly forward, and at the same time, when the second robot moves forward, the adsorption force of the vacuum chamber of the second robot is slowly released in sequence, so that the small piece of tape slowly falls off as the bonding progresses until the bonding is completed; 7) The bonded film assembly on the automatic lamination station is taken away.

[0010] The beneficial effects of the present invention are as follows: 1) The conveyor belt, U-shaped positioning plate, and the structure in which the manipulator and the first adsorption plate cooperate on the positioning station solve the problem of difficult positioning of the bonding position, with a simple structure and novel concept; 2) The use of a rotatable and liftable second manipulator and a pressing block structure cleverly solves the problem of bubbles easily appearing between the tape layers after the tape is bonded, while freeing the operator's hands and improving the bonding efficiency.

[0020] When in use, the process steps are as follows: 1) According to the production arrangement, the cut large piece of tape 24 and the small piece of tape 25 are manually placed on the large piece positioning station 1 and the small piece positioning station 3 respectively; 2) The first conveyor belt 6 and the first U-shaped guide plate 7 are used to cooperate to realize the positioning of the large piece of tape 24.
