[0058] Please refer to Figure 1 、 2 The embodiment provides a material covering control method, comprising the following steps:

[0059] S1. Obtain information that the first material is placed on the lower mold in the loading station, and control the first material to be pressed. Specifically, detect whether the first material is loaded to the lower mold arranged in the loading station; if yes, move the workbench to drive the lower mold in the loading station and the first material to move to the gluing station; if not, the workbench does not work. Wherein, the lower mold is arranged on the movable workbench; preferably, the lower mold is detachably fixed on the movable workbench in the loading station. Different types of lower molds and upper molds can be replaced according to products.

[0060] In an embodiment, photoelectric detection can be used to detect whether the first material is correctly placed on the lower mold.

[0061] In an embodiment, the loading of the first material is operated by manual operation; the lower mold is pressed and fixed on the movable workbench in a detachable manner by a pressing tool.

[0062] S2. Obtain the position information of the lower mold at the glue applying station, and control the glue applying on the laminated surface of the first material. Specifically, detect whether the moving workbench is at the glue applying station; if yes, the robot applies glue on the laminated surface of the first material; if no, the robot does not work. In this embodiment, a proximity switch can be used to detect whether the moving workbench is at the predetermined position (i.e. the glue applying station), and if the moving workbench at the glue applying station is not detected, the robot cannot be started. After the glue applying, the moving workbench drives the lower mold and the first material at the glue applying station to the laminating station.

[0063] In an embodiment, a glue machine system is provided, in which the glue temperature is 135°C, the internal pressure of the glue pipe is 40 bar, the glue applying speed is 200 mm / s, the glue width is about 2 mm, and the glue thickness is about 2 mm.

[0064] In an embodiment, after obtaining the position information of the lower mold at the glue applying station, the moving workbench can be locked to the laminating station. That is, at the predetermined position, the pin cylinder arranged on the moving workbench can lock the moving workbench to the predetermined position (i.e. the glue applying station).

[0065] S3. Obtain the position information of the lower mold at the laminating station, and control the second material to be placed on the laminated surface of the first material for glue applying. Specifically, detect whether the moving workbench is at the laminating station; if yes, place the second material on the laminated surface of the first material for glue applying; if no, do not place the second material. In this embodiment, a proximity switch can be used to detect whether the moving workbench is at the predetermined position (i.e. the laminating station).

[0066] In an embodiment, the placing of the second material is performed by a human. Preferably, the second material can be accurately placed along the guide structure to well cooperate with the first material. It can be understood that the human can be replaced by a robot.

[0067] In step S3, after obtaining the position information of the lower mold at the laminating station, the moving workbench can be locked to the laminating station. This step is S8. That is, at the predetermined position, the pin cylinder arranged on the moving workbench can lock the moving workbench to the predetermined position (i.e. the laminating station). Of course, before the moving workbench moves, the pin cylinder is unlocked, and the moving workbench can move.

[0068] S4. Obtain the information that the second material is placed on the first material, and control the upper mold to move towards the lower mold to press the second material to combine with the first material. Specifically, detect whether the second material is correctly placed; if yes, the upper mold driving assembly drives the upper mold to move towards the lower mold to press the second material to combine with the first material; if no, the upper mold driving assembly does not work. In this embodiment, a photoelectric detector can be used to detect whether the second material is correctly placed on the first material, and if the correct placement of the second material is not detected, the upper mold driving assembly cannot be started to perform the pressing operation.

[0069] In one embodiment, during the moving of the upper mold to the lower mold, the upper mold moves to a first position at a first speed, and then moves to a final pressing position at a second speed; wherein the first speed is greater than the second speed. Preferably, the first position refers to a position 10-15mm away from the second material or the lower mold, and further optionally 12mm. Preferably, the first speed is set in a range of 10-200mm / s, and further optionally 200mm / s. Preferably, the second speed is set in a range of 10-200mm / s, and further optionally 25mm / s.

[0070] S5. After the pressure maintaining, the upper mold is controlled to be separated from the lower mold. Specifically, after the pressure maintaining, the upper mold driving assembly drives the upper mold to move reversely and be separated from the lower mold. Preferably, the upper mold moves downward and engages with the lower mold, and then the upper mold moves upward and returns to the original position.

[0071] In one embodiment, the pressure maintaining time is adjusted according to actual production needs, such as 20s. The speed of the upper mold separated from the lower mold is greater than the first speed, and is set in a range of 10-200mm / s, and preferably 180mm / s.

[0072] S9. The moving workbench is controlled to move to a lower piece station, and the coated material product is taken out at the lower piece station. It can be understood that the taking out can be operated by manual operation, and can also be operated by mechanical operation.

[0073] S10. The information of the lower mold without the coated material product is obtained, and the moving workbench is controlled to return to the upper piece station. Specifically, it is detected whether the coated material product exists in the lower mold; if not, the moving workbench drives the lower mold to return to the upper piece station, and the material coating-pressing-pressure maintaining operation of the first material is performed in the next round; if yes, the moving workbench does not work.

[0074] In one embodiment, the photoelectric detection can be used to detect whether the coated material product is left in the lower mold (the coated material product needs to be taken out in time to perform the coating operation on the first material in the next round), if yes, the moving workbench cannot return to the upper piece station; if not, the moving workbench returns to the upper piece station. In the upper piece station, the latch cylinder can also lock the moving workbench to be fixed.

[0075] In the above steps, the moving workbench is used to move the lower mold and / or the first material between the gluing station and the upper station and / or between the gluing station and the laminating station. In detail, the moving workbench moves the lower mold and / or the first material between any two of the upper station, the gluing station and the laminating station. At this time, the upper station, the gluing station and the laminating station are three different stations. In addition, the upper station and the laminating station can also be set as the same station, which will be described below. Preferably, the moving speed of the moving workbench is set to 10-800 mm / s, and further preferably 600 mm / s. The movement of the moving workbench connects the stations in series and connects the corresponding processes of the stations in series, thereby improving the production efficiency.

An example is provided below, the brand and model of the glue is -700PUR-Hotmelt for headlamp assembly; the glue is a single-component, PUR moisture curing reaction type hot melt adhesive; the open time of the glue is 30 s.

[0080] In an embodiment, a hot air unit is used to preserve the glue and / or detect the temperature; wherein the hot air unit includes a hot air component and / or a temperature measuring component. The hot air component is used to blow hot air to preserve the glue coated on the first material; wherein the hot air component is heated by a hot air machine, the hot air is transmitted to the material lamination equipment (which can be a gluing and laminating equipment) through a high-temperature air pipe, and finally the hot air is blown to the surface of the first material through an air nozzle; the hot air machine is installed on the side of the material lamination equipment. Preferably, the temperature adjustment range of the hot air machine is room temperature-200°C, and the air speed is not strictly required. Further, the temperature measuring component is used to measure the temperature of the first material and / or the hot air; the temperature measuring component is preferably an infrared temperature measuring probe. The temperature measuring frequency of the temperature measuring component can be 200 ms per time.

[0081] In one embodiment, the robot is fixedly arranged for performing the gluing operation in cooperation with the gluing station; the execution end of the robot is provided with a glue gun assembly for gluing.

Hereinafter, a robot selection is provided, the robot model is ABB IRB2600-165-20, the robot arm span is 1.65 m, the repeatability accuracy is ±0.02 mm, and the load is 20 kg.

[0082] In one embodiment, in step S3, when the second material is placed, the press of the fixed lower mold is opened, the second material is accurately placed on the lower mold along the guide structure, so that the second material is well adapted to the first material, and then the press is pressed to the first material and / or the second material. According to the understanding, this is conducive to the smooth demolding of the upper and lower molds, the demolding of the glued and pressed product, and the detection of whether the glued and pressed product is taken out.

[0083] In one embodiment, the loading station and the lamination station are the same station. That is, both the first material and the second material are loaded in the lamination station, which can further improve the work efficiency.

[0084] The material lamination control method of the present application connects the gluing process and the pressing process in series, and accurately detects and effectively controls, so that the artificial only needs to perform the taking and placing operation, thereby improving the automation degree. In which, the robot is used for gluing, thereby improving the stability of the gluing quality. At the same time, the hot air unit can heat the gluing area and the glue at the same time of gluing, thereby effectively prolonging the opening time of the glue, and facilitating the effective combination of the first material and the second material.

[0099] Embodiment Three

[0100] Please refer to Figures 4-7 The present embodiment provides a glue coating and pressing equipment, which can apply the material lamination control device and / or the material lamination control method.

The moving workbench 2 is fixedly arranged on the rack 1, and is used to move between the workpiece loading station, the glue coating station and the laminating station. The workpiece loading station is used for loading the first material; the glue coating station is used for coating glue; and the laminating station is used for loading the second material and pressing the first material. The rack 1 provides a basis for the installation of parts, and the structure of the rack 1 is preferably integral.

In one embodiment, the moving workbench 2 moves from the workpiece loading station, passes through the glue coating station and the laminating station, and returns to the workpiece loading station.

[0103] In one embodiment, as Figure 5 The workbench support 10 is fixedly arranged, and can be fixedly arranged on the bottom of the rack 1. The moving workbench 2 is slidingly connected to the workbench support 10, and is used to carry the mold / glue coating and pressing tooling; the moving workbench 2 is driven to move along the length direction of the workbench support 10 by the ball screw 11. The pin air cylinder is used to lock the moving workbench 2 at the preset position, that is, when the moving workbench 2 moves to the work station, it can be locked to the workpiece loading station, the glue coating station and the laminating station, so as to facilitate the operation at the above work stations. A guide mechanism is arranged between the moving workbench 2 and the workbench support 10, and is used to guide the movement of the moving workbench 2. When the moving workbench 2 works, the ball screw 11 drives the moving workbench 2 to move along the length direction of the workbench support 10. When the moving workbench 2 moves to the preset work station, the pin of the pin air cylinder extends into the insertion hole of the workbench support 10, that is, the moving workbench 2 is locked. At this time, the mold, the glue coating and pressing tooling or the material on the moving workbench 2 at the work station can be operated (wherein the positioning pin 18 realizes positioning).

The movable die plate 29 is arranged below the fixed die plate 30 and opposite to the fixed die plate 30; the lifter is arranged on the fixed die plate 30; the action end of the lifter is connected with the movable die plate 29, and the lifter is used for driving the movable die plate 29 to vertically ascend and descend, that is, the movable die plate 29 moves towards the lower die 49. Specifically, the lifter comprises: a first servo motor 36, a speed reducer 35 and a lifting rod 34. The speed reducer 35 is in transmission connection with the first servo motor 36; the lifting rod 34 is vertically arranged; and the first end of the lifting rod 34 is fixedly connected with the movable die plate 29. Moreover, the rod body of the lifting rod 34 is formed with a rack; the rack of the lifting rod 34 is in meshing transmission with a driving gear in the speed reducer 35; and the driving gear of the speed reducer 35 drives the lifting rod 34 to ascend and descend, thereby driving the movable die plate 29 to synchronously ascend and descend. Wherein, the first servo motor 36 provides power, and when the upper die driving assembly 3 drives the upper die 50 to ascend or descend, the position of the ascending or descending can be precisely controlled; and the pressing depth and pressing speed of the upper die driving assembly 3 driving the upper die 50 to cooperate with the lower die 49 can be conveniently and timely adjusted.

[0106] In an embodiment, as Figure 7 The rubber coating and pressing tooling comprises the upper die 50 and the lower die 49 which cooperate with each other. The upper die 50 and the lower die 49 can constitute a mold.
