Description

Technical Field

[0001] The invention relates to hot pressing laminating equipment and a laminating method. Background Art

[0002] When the existing PI material is hot pressed on PFC, it is easy to have defects such as bubbles and pits, such as Figure 4 As shown, after testing, it was found that this was mainly due to the loose backing of the PI material and the insufficient pressure of the roller, which resulted in residual bubbles during the backing, causing the bubbles to be discharged under high temperature and high pressure, resulting in uneven flow, expansion and evaporation. Based on this, most of the current methods are to increase the backing pressure or reduce the backing speed to improve the problem. However, there is a pressure upper limit for increasing the backing pressure, and reducing the backing speed will also reduce the processing efficiency. Therefore, some people use dot matrix preheating pressing to solve the bubble problem, but the current dot matrix preheating pressing structure has poor flexibility, especially when changing different styles of workpieces to be hot-pressed, manual adjustment and adaptation are still required. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a hot pressing laminating device and a laminating method that are more flexible and can automatically adjust and adapt a lattice preheating and pressing structure.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A hot pressing bonding device includes a frame, and a pre-pressing device and a hot pressing device installed on the frame. The frame includes an upper workbench and a lower workbench. The pre-pressing device and the hot pressing device are arranged on the upper workbench to form a downward pressing operation. The pre-pressing device includes a pre-pressing motor and a dot matrix pre-pressing plate driven by the pre-pressing motor. The hot pressing device includes a hot pressing motor and a hot pressing plate driven by the hot pressing motor. A front camera and a rear camera are also installed on the frame.

[0006] Preferably, the dot matrix pre-pressing plate includes a dot matrix plate body, a plurality of dot matrix holes provided on the dot matrix plate body, a plurality of dot matrix hot pressing heads matched with the dot matrix holes, and a servo motor for controlling the extension and retraction of the dot matrix hot pressing heads within the dot matrix holes.

[0007] Preferably, the lower pressing surface of the dot matrix plate is concave, and the depth of the concave is consistent with the telescopic length of the dot matrix hot pressing head.

[0008] Preferably, the front camera and the rear camera are rotatably connected to the upper workbench position of the frame.

[0009] Another technical problem to be solved by the present invention is to provide a hot pressing lamination method, comprising the following steps:

[0010] The front camera is used to capture images of the workpiece to be hot-pressed at the entrance of the shooting rack, and the shooting results are sent to the server for recognition processing;

[0011] The server sends a control command to the pre-pressing device based on the recognition result, and performs dot matrix pre-pressing on the workpiece to be hot-pressed that passes through the front camera and enters the bottom of the pre-pressing device;

[0012] The workpiece that has been pre-heated and pressed in the dot matrix mode is sent to the bottom of the hot pressing device for full hot pressing;

[0013] The rear camera is used to capture images of the workpieces that have completed hot pressing at the exit of the shooting rack, and the shooting results are sent to the server for recognition processing.

[0014] Preferably, after receiving the control command sent by the server, the pre-pressing device controls the dot matrix hot pressing head to expand and contract, and forms a dot matrix distribution structure that matches the workpiece to be hot pressed.

[0015] Preferably, when the server side identifies and determines that the workpiece has a hot pressing defect, it sends a compensation command to the servo motor. The servo motor controls the dot matrix hot pressing head to extend and retract based on the received compensation command, and forms a gradual compensation adjustment for the original dot matrix distribution structure until the server side identifies and determines that the workpiece does not have a hot pressing defect.

[0016] Preferably, when the server side identifies and determines that the workpiece does not have hot pressing defects, it sends a maintenance command to the servo motor. The servo motor maintains the current dot matrix distribution structure based on the received maintenance command until it receives a new compensation instruction or receives a control command for another dot matrix distribution structure.

[0017] Preferably, several types of dot matrix distribution structures are pre-stored in the server side, and each dot matrix distribution structure matches a corresponding control command. When the server side receives the image acquisition data, it performs mechanical vision recognition and matches it with the dot matrix distribution structure based on the recognition result, and finally sends the matched control command to the servo motor.

[0018] Preferably, the method by which the servo motor controls the extension and retraction of the dot matrix thermal pressing head based on the received compensation command is: compensating for the extension and retraction length and amount of the dot matrix thermal pressing head, and the length and amount of each compensation are preset fixed values.

[0019] The beneficial effects of the present invention are:

[0020] By using the front camera and the rear camera to adjust and control the pre-pressing device, it is possible to automatically match the corresponding pre-pressing device lattice arrangement structure for pre-heating and pressing according to the workpiece identification at the entry end, and to identify the hot pressing defects at the exit end and make compensation adjustments to the lattice arrangement structure, thereby improving the effect of pre-heating and pressing, and ultimately achieving the effect of automatically adjusting the lattice hot pressing without the need for manual adjustment operations, which is highly flexible.

[0028] Example

[0029] See Figure 1-3 As shown, a hot pressing bonding device includes a frame 1, and a pre-pressing device 2 and a hot pressing device 3 installed on the frame 1, the frame 1 includes an upper workbench 11 and a lower workbench 12, the pre-pressing device 2 and the hot pressing device 3 are arranged on the upper workbench 11 to form a downward pressing operation, the pre-pressing device 2 includes a pre-pressing motor 21, and a dot matrix pre-pressing plate 22 driven by the pre-pressing motor 21, the hot pressing device 3 includes a hot pressing motor 31, and a hot pressing plate 32 driven by the hot pressing motor 31, and a front camera 4 and a rear camera 5 are also installed on the frame 1.

[0030] The dot matrix pre-pressing plate 22 includes a dot matrix plate body 221, a plurality of dot matrix holes 222 opened on the dot matrix plate body 221, a plurality of dot matrix hot pressing heads 223 matched with the dot matrix holes 222, and a servo motor 224 for controlling the extension and retraction of the dot matrix hot pressing heads 223 in the dot matrix holes 222. The lower pressing surface of the dot matrix plate body 221 is concave, and the depth of the concave is consistent with the extension length of the dot matrix hot pressing heads 223.

[0031] By controlling the expansion and contraction of a plurality of dot matrix hot pressing heads 223 in the dot matrix hole body 222, a plurality of different dot matrix preheating and pressing structures are arranged, and the workpiece to be preheated and pressed is subjected to dot matrix preheating and pressing. The dot matrix preheating and pressing structure can be in the shape of strips, curves, prisms, etc., and the specific arrangement shape is based on the pre-existing arrangement shape in the server end.

[0032] The front camera 4 and the rear camera 5 are distributed and rotatably connected to the upper workbench 11 of the frame 1. It should be noted that the front camera 4 and the rear camera 5 are aimed at the passing position of the workpiece to collect image data, and send the collected image data to the server for processing, and the server performs mechanical visual judgment on the received image data. The mechanical visual judgment method can use the mark attached to the workpiece for identification code recognition, or use a target recognition method based on shape and size as features, specifically based on the ability to determine the type of workpiece and match the corresponding dot matrix arrangement structure.

[0033] A hot pressing lamination method comprises the following steps:

[0034] The front camera is used to capture images of the workpiece to be hot-pressed at the entrance of the shooting frame 1, and the shooting results are sent to the server for recognition processing;

[0035] The server sends a control command to the pre-pressing device 2 based on the recognition result, and performs dot matrix pre-pressing on the workpiece to be hot-pressed that passes through the front camera 4 and enters the bottom of the pre-pressing device 2;

[0036] The workpiece that has been pre-heated and pressed in the dot matrix mode is fed into the bottom of the hot pressing device 3 for full hot pressing;

[0037] The rear camera 5 is used to capture images of the workpiece that has completed hot pressing at the exit of the shooting frame 1, and the shooting results are sent to the server for recognition processing.

[0038] After receiving the control command sent by the server, the pre-pressing device 2 controls the dot matrix hot pressing head 223 to expand and contract, and forms a dot matrix distribution structure that matches the workpiece to be hot pressed.

[0039] When the server side identifies and determines that the workpiece has a hot pressing defect, it sends a compensation command to the servo motor 224. The servo motor 224 controls the dot matrix hot pressing head 223 to extend and retract based on the received compensation command, and forms a gradual compensation adjustment for the original dot matrix distribution structure until the server side identifies and determines that the workpiece does not have a hot pressing defect.

[0040] The hot pressing defects mainly include bubbles and pits that appear when hot pressing PI material on the workpiece.

[0041] When the server side identifies that there is no hot pressing defect in the workpiece, it sends a maintenance command to the servo motor 224. The servo motor 224 maintains the current dot matrix distribution structure based on the received maintenance command until receiving a new compensation instruction or receiving a control command for another dot matrix distribution structure.

[0042] The server side has several types of dot matrix distribution structures pre-stored, and each dot matrix distribution structure matches a corresponding control command. When the server side receives the image acquisition data, it performs mechanical vision recognition and matches it with the dot matrix distribution structure based on the recognition result, and finally sends the matched control command to the servo motor 224.

[0043] The method in which the servo motor 224 controls the extension and retraction of the dot matrix hot pressing head 223 based on the received compensation command is: compensating for the extension length and extension amount of the dot matrix hot pressing head 223, and the length and amount of each compensation are preset fixed values. In this embodiment, the extension length compensation value is 0.1-0.5mm, and for the extension amount compensation, a circle of the dot matrix hot pressing head 223 is added to the outermost circle to extend it. Generally speaking, either method can be selected, and there is no need to use both methods at the same time.

[0044] The beneficial effects of the present invention are:

[0045] By using the front camera and the rear camera to adjust and control the pre-pressing device, it is possible to automatically match the corresponding pre-pressing device lattice arrangement structure for pre-heating and pressing according to the workpiece identification at the entry end, and to identify the hot pressing defects at the exit end and make compensation adjustments to the lattice arrangement structure, thereby improving the effect of pre-heating and pressing, and ultimately achieving the effect of automatically adjusting the lattice hot pressing without the need for manual adjustment operations, which is highly flexible.

[0046] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
