Description

Technical Field

[0001] The invention relates to a top-bottom cover type online degassing machine, belonging to the field of automated intelligent manufacturing and the field of full lamination technology. Background Art

[0002] Full bonding technology is the mainstream development trend of high-end smart phones, watches and tablet computer panels. The panel and the touch screen are completely glued together in a seamless manner to provide better screen reflection image display effects. High-pressure degassing is an indispensable full bonding process for the assembly of OCA optical adhesive in 3C mobile phone screens at this stage.

[0003] The actual production process of existing panel bonding is to manually transport materials to the equipment for high-pressure degassing. Most of the degassing equipment currently used on the market are tank-type degassing machines. The internal structure is equipped with multi-layer racks, and the products need to be manually stacked neatly on the racks. It takes 8-12 minutes to complete a degassing process, and 5-8 minutes to manually transport the materials. In addition, because the upstream and downstream equipment cannot be connected for production during the product manufacturing process, it is easy to cause stagnation in the production process, causing the downstream process to wait for the degassing to be completed before manually transporting the materials for production. Due to this drawback, the production is limited so that most manufacturers can only complete part of the assembly process, and cannot realize the entire production process of the product and increase production capacity. In addition, the current tank-type degassing machines on the market have a large product base for single degassing. When the control parameters are in error or out of control, it is easy to cause poor batch quality and poor product yield control. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing degassing machine is prone to stagnation during the production process, and when the control parameters are in error or out of control, it is easy to cause poor batch quality and poor product yield control.

[0005] In order to solve the above problems, the present invention provides a top and bottom cover type online degassing machine, comprising a frame assembly, a feeding conveying line and a correction mechanism, a loading and handling manipulator, a unloading and handling manipulator, a discharging conveying line and a correction mechanism, a connecting manipulator, a transplanting platform, and a top and bottom cover type sealing structure;

[0006] The feeding conveyor line and the correction mechanism are installed at the feeding port on the left side of the frame assembly, the transplanting platform is installed above the frame assembly, the sky and earth cover type sealing structure is installed above the transplanting platform, the loading and unloading handling robot is installed on both sides above the sky and earth cover type sealing structure respectively, the discharging conveyor line and the correction mechanism are installed on one side above the frame assembly, and the connecting robot is arranged on one side of the frame assembly.

[0007] Furthermore: the feed conveyor line and correction mechanism, the discharging conveyor line and correction mechanism all use optical fiber detection positioning and cylinder correction action. The cylinder is provided with a forward and backward moving slider and left and right slider mounting holes. The feed conveyor line and the correction mechanism are provided with a movable supporting foot cup at the bottom.

[0008] Furthermore: the loading and handling robot can automatically calculate the stacking incremental height according to the set product thickness and quantity.

[0009] Furthermore: the material unloading and handling robot adopts a servo motor and a linear module structure, and an adjustable position vacuum nozzle to achieve product handling in three directions: up and down, left and right, and front and back.

[0010] Furthermore: the in-line robot adopts a servo motor, a linear module structure and a rotary cylinder to realize the movement of product transportation in the front, back, up and down and rotation directions.

[0011] Furthermore: the transplanting platform adopts a servo motor and a linear module structure to achieve forward and backward movement.

[0012] Furthermore: the top and bottom cover type sealing structure adopts a cylinder plus a linear bearing to realize the up and down and rotational coordination action.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. Use the top and bottom cover sealing structure to achieve a sealed and compact degassing environment. Effectively shorten the production cycle time of the product to 6-7 minutes. The multi-station design can achieve independent loading, independent degassing, independent unloading, and non-stop production of the downstream equipment, thereby improving the overall production capacity of the production line and solving production shortcomings.

[0015] 2. This patent has four workstations with a total of eight workstations, which can be individually set to save parameters and suspend use, avoiding the problem of downtime due to the need to replace the structural parts of a single workstation after wear.

[0016] 3. The equipment is equipped with upstream and downstream material timeout alarms to promptly remind engineering personnel to judge the production situation.

[0017] 4. The number of single degassing in this patent is less than that of traditional degassing. However, when the equipment is affected by other uncontrollable factors such as parameter errors, confusion, power outages, etc., it has better controllability and better control over the overall production process.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Combined with Figure 1-10 The present invention provides a top and bottom cover type online degassing machine, comprising a frame assembly, a feeding conveying line and a correction mechanism, a loading and handling manipulator, a unloading and handling manipulator, a discharging conveying line and a correction mechanism, a connecting manipulator, a transplanting platform, and a top and bottom cover type sealing structure;

[0040] The rack assembly is used to fix and place the mechanisms required for the equipment processing process;

[0041] The left side feed port of the feed conveyor line and correction mechanism frame assembly adopts positioning optical fiber assembly positioning and correction cylinder assembly correction action, which is used to receive the product conveying positioning and product position correction after processing by the upstream equipment. The correction cylinder assembly is equipped with forward and backward moving sliders and left and right slider mounting holes, which can be moved to the appropriate correction position according to the size of the product. The bottom of the feed conveyor line and correction mechanism is equipped with a movable support foot cup, which can adjust the overall height of the feed conveyor line according to the height of the upstream equipment to facilitate the reception of upstream products;

[0042] The loading and handling robot is installed above the top and bottom cover sealing structure. It adopts servo motor, linear module structure and vacuum adsorption component to realize the reciprocating movement of product handling in the up and down and left and right directions. It is used to transport the products that have been calibrated on the feeding conveyor line to the eight workstations for stacking and stacking. The robot is equipped with an automatic height calculation function, which can automatically calculate the incremental height of stacking and stacking according to the set product thickness and quantity;

[0043] The unloading and handling robot is installed above the top and bottom cover sealing structure. It adopts servo motor and linear module structure plus adjustable position vacuum suction nozzle adsorption to realize the movement of product handling in three directions: up and down, left and right, and front and back. It is used to realize the unloading movement of products in eight workstations after degassing. The left side of the up and down handling place is equipped with a blowing and sheeting component and an anti-stacking shaking cylinder component, which are used for blowing and sheeting after degassing. It can realize the adjustment of up and down, left and right and angle to adapt to products of different sizes. The robot is equipped with an automatic height calculation function, which can automatically calculate the stacking descending height according to the set product thickness and quantity;

[0044] The unloading conveyor line and correction mechanism are installed on one side above the frame assembly. The positioning optical fiber assembly is used for positioning and the correction cylinder assembly is used for correction. It is used to convey the products that have been handled by the unloading handling robot, and convey them to the handling position of the connecting robot and correct the product position. The cylinder assembly is also equipped with forward and backward moving sliders and left and right slider mounting holes, which can be moved to the appropriate correction position according to the size of the product.

[0045] The in-line manipulator is located on one side of the frame assembly, and uses a servo motor and linear module structure, as well as an in-line rotary cylinder assembly, to achieve the front-to-back, up-and-down, and rotational movements of the product, and is used to reciprocate the transported product to the downstream equipment conveyor line;

[0046] The transplanting platform is installed above the frame assembly, and uses a servo motor and a linear module structure to achieve forward and backward movement. There are four parallel workstations, and two left and right workstations are set inside the structure, with a total of eight workstations, which receive materials transported by the feeding robot to the sealed tank structure. There is an automatic product correction structure inside, which can adjust the actual correction position according to the product size, so as to facilitate the material picking accuracy of the connected robot after the discharge conveyor line and the correction mechanism conveys and corrects;

[0047] The top and bottom cover sealing structure is installed above the transplanting platform. It adopts upper and lower cylinder assemblies, rotating cylinder assemblies and linear bearings to realize up and down and rotating coordinated actions. After cooperating with the sealed tank structure, the air intake and pressurization are realized through the air pipe and the solenoid valve control connection through parameter setting, so that the air pressure in the closed structure is increased, and the bubbles in the product are squeezed out by the air pressure. The top and bottom cover sealing structure has a total of four stations, each of which has a separate air intake and outlet interface, and a data detection table. Each station realizes separate air intake and pressurization operation, and the data simulation value input can be realized within the air pressure range of 0.05-0.6Kgf. The mechanism can add heating function according to product requirements, and preheat the sealed tank structure through the peripheral burden heating component to ensure the constant temperature in the structure, which significantly improves the degassing effect of the product and further reduces the time required for degassing.

[0048] The present invention provides a top and bottom cover type online degassing machine, which comprises the following process steps:

[0049] S1-Feeding: The products processed by the upstream equipment are transported to the optical fiber detection and positioning position through the feeding conveyor line, and the cylinder is automatically calibrated. The loading and handling robot automatically identifies the optical fiber signal and moves to the positioning position for vacuum adsorption. The products are transported to the eight work stations in the transplanting platform in turn and automatically stacked and placed according to the number of products set by the parameters.

[0050] S2-Degassing: When the number of products at a single workstation in the transplanting platform reaches the number set by the parameters, they are automatically transported to the bottom of the top-bottom cover sealing structure. The cylinder of the corresponding workstation above presses the upper cover into place and then rotates to seal with the sealed tank structure. Then, the solenoid valve is switched according to the set parameters to intake air and pressurize, and the pressure is maintained for the set time to degas. During this period, the air pressure can be automatically identified to automatically increase and reduce pressure to ensure the stability of the internal air pressure. After the pressure holding time is reached, the air valve is automatically opened to release the pressure and exhaust. After the air pressure reaches the minimum set value, it rotates and rises to open the upper cover and separate it from the mechanism, and the degassing action is completed.

[0051] S3-Unloading: After degassing is completed, the transplanting platform is automatically sent to the rear of the rack assembly. The unloading and handling robot vacuum absorbs the products in turn according to the set height and quantity of loading and transports them to the unloading conveyor line to be transported to the optical fiber detection positioning and correction products.

[0052] S4-Connection: The connection robot automatically identifies the fiber optic detection signal on the unloading conveyor line and then vacuum-adsorbs and transports the product to the downstream equipment conveyor line, and rotates or shifts the material placement according to the needs of the downstream equipment.

[0053] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
