[0002] In the home appliance manufacturing industry, the combination of glass sheets and plastic panels is very common. For example, many home appliance designs, such as refrigerators, air conditioner cabinets, disinfection cabinets, microwave ovens, and dishwashers, have adopted this process to improve the user experience.

[0003] However, glass panels are fragile, especially colored glass, which is easily scratched and affects the appearance. Therefore, on general production lines, a multi-station manual pasting and assembly method is used. The pearl cotton used to absorb shock and prevent scratches between the glass panels needs to be manually removed. Simple positioning fixtures are used to complete the loading, unloading and assembly operations. The workload is very large, the labor efficiency is low, and there is also the risk of glass breaking and injuring people.

[0033] Please see Figures 1 to 6 This utility model provides a transfer clamp that combines film tearing and weighing, comprising:

[0034] A film-tearing mechanism 1 is used to tear off the plastic protective film on the glass plate;

[0035] Adsorption mechanism 2, which is connected to film-tearing mechanism 1, is used to adsorb glass plate;

[0036] Hinge support 3, which is mounted on the top of the adsorption mechanism 2;

[0037] Weighing mechanism 4, which is installed on top of adsorption mechanism 2;

[0038] Connecting arm 5, which is mounted on the transfer machine and connected to the hinge support 3 and the weighing mechanism 4.

[0039] When the transfer machine moves the transfer clamp, which combines film tearing and weighing, close to the stacked glass plates via the connecting arm 5, the film tearing mechanism 1 tears the pearl cotton between the stacked glass plates and the plastic protective film on the surface of the glass plates. The transfer machine continues to move and pull the plastic protective film with the transfer clamp that combines film tearing and weighing until the film tearing mechanism 1 completely peels off the plastic protective film on the glass plates. Then, the transfer machine moves the transfer clamp that combines film tearing and weighing to the waste recycling area. The film tearing mechanism 1 releases the pearl cotton and the plastic protective film, causing the plastic protective film to fall into the waste recycling area.

[0040] Then, the transfer machine brings the transfer fixture, which combines film tearing and weighing, closer to the stacked glass plates. The adsorption mechanism 2 adsorbs the glass plates. At the same time, the weighing mechanism 4 weighs the film tearing mechanism 1, the adsorption mechanism 2, and the glass plates. The transfer machine brings the transfer fixture, which combines film tearing and weighing, closer to the production line. The adsorption mechanism 2 places the glass plates on the production line, and the production line transports the glass plates to the next station.

[0041] In a preferred embodiment, the film-tearing mechanism 1 includes a support 11, a lifting cylinder 12, a gripper cylinder 13, and a needle suction cup 14; the support 11 is connected to the adsorption mechanism 2, the lifting cylinder 12 and the gripper cylinder 13 are mounted on the support 11, the needle suction cup 14 is connected to the telescopic rod of the lifting cylinder 12, and the lifting cylinder 12 drives the needle suction cup 14 to move up and down.

[0042] When the transfer machine, via connecting arm 5, moves the transfer clamp, which combines film tearing and weighing functions, close to the stacked glass plates, the lifting cylinder 12 of the film tearing mechanism 1 drives the needle suction cup 14 to descend, bringing it close to the pearl cotton and plastic protective film. The needle suction cup 14 tears open the pearl cotton and the plastic protective film on the surface of the glass plates. Then, the lifting cylinder 12 drives the needle suction cup 14 to rise back to its original position.

[0043] Then, the two grippers 131 of the gripper cylinder 13 come together and clamp the pearl cotton and the plastic protective film. The transfer machine continues to drive the transfer fixture, which combines film tearing and weighing, to move until the film tearing mechanism 1 completely peels off the plastic protective film on the glass plate. The transfer machine then drives the transfer fixture, which combines film tearing and weighing, to move to the waste recycling area. The two grippers 131 of the gripper cylinder 13 of the film tearing mechanism 1 separate and release the pearl cotton and the plastic protective film, causing the plastic protective film to fall into the waste recycling area.

[0044] In a preferred embodiment, the film-tearing mechanism 1 further includes a buffer assembly 15, which includes a connecting plate 151, a damper 152, and a mounting block 153. The connecting plate 151 is connected to the telescopic rod of the lifting cylinder 12, the damper 152 is mounted on the connecting plate 151, the mounting block 153 is connected to the damper 152, and the needle suction cup 14 is mounted on the mounting block 153.

[0045] Thus, when the lifting cylinder 12 drives the needle suction cup 14 to descend close to the plastic protective film on the glass plate, the impact force can be buffered by installing a buffer assembly 15 between the lifting cylinder 12 and the needle suction cup 14, so as to avoid the excessive force applied by the lifting cylinder 12 and the needle suction cup 14, which would cause the glass plate to be crushed.

[0046] In a preferred embodiment, the adsorption mechanism 2 includes a mounting plate 21 and a vacuum suction cup 22. The support 11 is connected to the mounting plate 21, and the vacuum suction cup 22 is mounted on the mounting plate 21 and extends downward. The vacuum suction cup 22 is used to adsorb the glass plate. It should be noted that an external air pipe provides negative pressure to the vacuum suction cup 22, and a pressure sensor can be installed in the external air pipe to detect the adsorption pressure of the vacuum suction cup 22.

[0047] In a preferred embodiment, the hinge support 3 includes an upper hinge support 31, a lower hinge support 32, and a rotary pin 33; the support plate 51 of the connecting arm 5 is connected to the upper hinge support 31, the lower hinge support 32 is mounted on the mounting plate 21, and the rotary pin 33 passes through the upper hinge support 31 and the lower hinge support 32 to assemble the upper hinge support 31 and the lower hinge support 32 together, so that the upper hinge support 31 and the lower hinge support 32 can swing around the rotary pin 33.

[0048] In a preferred embodiment, the weighing mechanism 4 includes an upper connecting block 41, a lower connecting block 42, and a weighing sensor 43; the support plate 51 of the connecting arm 5 is fixedly installed with the upper connecting block 41, the weighing sensor 43 is fixedly installed between the upper connecting block 41 and the lower connecting block 42, and the lower connecting block 42 is mounted on the mounting plate 21.

[0049] This design allows the adsorption mechanism 2 to swing under the hinge support 3 when the connecting arm 5 is connected to the hinge support 3 and the weighing mechanism 4. Since the film-tearing mechanism 1 is mounted on the adsorption mechanism 2, the combined weight of the adsorption mechanism 2 and the film-tearing mechanism 1 is applied to the weighing sensor 43. The weighing sensor 43 of the weighing mechanism 4 detects the total weight of the adsorption mechanism 2 and the film-tearing mechanism 1. When the vacuum suction cup 22 completely adsorbs the glass plate, the weighing sensor 43 of the weighing mechanism 4 detects the total weight of the adsorption mechanism 2, the film-tearing mechanism 1, and the glass plate. The weight of the glass plate can be obtained by subtracting the total weight of the adsorption mechanism 2 and the film-tearing mechanism 1 from the total weight of the adsorption mechanism 2, the film-tearing mechanism 1, and the glass plate.

[0050] If the connecting arm 5 is directly fixedly connected to the adsorption mechanism 2 and the film-tearing mechanism 1, the weighing sensor 43 cannot accurately detect the force applied to the weighing sensor 43 by the adsorption mechanism 2 and the film-tearing mechanism 1, and thus cannot complete the weighing.

[0051] In a preferred embodiment, the weighing mechanism 4 further includes a protective component 44, which includes an upper mounting block 441, a lower mounting block 442, and a telescopic column 443. The upper mounting block 441 is connected to the upper connecting block 41, the support plate 51 of the connecting arm 5 is located between the upper mounting block 441 and the upper connecting block 41, the lower mounting block 442 is connected to the lower connecting block 42, and the lower mounting block 442 is also connected to the mounting plate 21. The telescopic column 443 is interposed on the upper mounting block 441 and the lower mounting block 442.

[0052] Thus, when the upper connecting block 41, the lower connecting block 42, and the load cell 43 bear excessive weight, they may easily become loose. Therefore, the design of the protective component 44 can increase the stability of the installation of the upper connecting block 41, the lower connecting block 42, and the load cell 43 and prevent them from becoming loose.

[0053] Furthermore, when the adsorption mechanism 2 swings under the hinge support 3, the telescopic column 443 will extend and retract synchronously, which will not affect the detection of the weighing sensor 43.

[0054] Working principle: When the transfer machine, via connecting arm 5, moves the transfer clamp, which combines film tearing and weighing functions, close to the stacked glass plates, the lifting cylinder 12 of the film tearing mechanism 1 drives the needle suction cup 14 to descend, bringing the needle suction cup 14 close to the plastic protective film. The needle suction cup 14 tears open the pearl cotton and the plastic protective film on the glass plate. Then, the lifting cylinder 12 drives the needle suction cup 14 to rise back to its original position.

[0055] The two grippers 131 of the gripper cylinder 13 come together and clamp the pearl cotton between the stacked glass plates and the plastic protective film attached to the surface of the glass plates. The transfer machine continues to drive the transfer clamp that combines film tearing and weighing to move and pull the plastic protective film until the film tearing mechanism 1 completely tears the plastic protective film on the glass plate. The transfer machine then drives the transfer clamp that combines film tearing and weighing to move to the waste recycling area. The two grippers 131 of the gripper cylinder 13 of the film tearing mechanism 1 separate and release the plastic protective film, causing the plastic protective film to fall into the waste recycling area.

[0056] Then, the transfer machine brings the transfer fixture, which combines film tearing and weighing, closer to the stacked glass plates. The adsorption mechanism 2 adsorbs the glass plates. At the same time, the weighing mechanism 4 weighs the film tearing mechanism 1, the adsorption mechanism 2, and the glass plates. The transfer machine brings the transfer fixture, which combines film tearing and weighing, closer to the production line. The adsorption mechanism 2 places the glass plates on the production line, and the production line transports the glass plates to the next station.

[0057] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
