[0020] 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.

[0021] Embodiment 1

[0022] Reference Figure 1 As shown, this embodiment discloses an automated manufacturing method for a bulletproof insert plate, comprising the following steps:

[0023] S1, cutting: The sheet is cut to the target size using laser, forming several buffer layers and fed into the main conveyor.

[0024] Specifically, the plate is first fixed, the target size of the buffer layer is preset on the laser cutting machine, the laser cutting machine automatically identifies the outer contour of the plate, and divides the plate into several buffer layers according to the target size, and uses the laser to cut the plate into several buffer layers along the divided path, and the manipulator loads the buffer layers one by one into the sub-conveyor belt, and the sub-conveyor belt conveys the buffer layers to the plate station of the main conveyor belt, and a mold is set on the plate station, and the buffer layer is fixed in the center of the mold by a latch through the way of locking, and the main conveyor belt is transported according to the set operation process and time interval. Preferably, the time interval is 3s-5s.

[0025] Since the target sizes of different parts are different, in order to improve the utilization rate of the plate, buffer layers of different target sizes can be cut out from the same plate.

[0026] The material of the plate is PE plate. Preferably, the PE plate includes but is not limited to aramid plate or PBO plate.

[0027] In a preferred embodiment of the present invention, the length a of the buffer layer is 250mm-350mm, and the width b is 200mm-300mm, that is, the target size is 250mm-350mm*200mm-300mm. Preferably, the target size is 250mm-300mm.

[0028] S2, Gluing: Remove the buffer layer from the main conveyor belt and place it in the glue dispensing station, identify the glue coating area, set the glue coating thickness, and calculate the glue coating amount. Pour a certain amount of glue into the production box and evenly coat it on the buffer layer. Let it stand for 5min-10min and then send it back to the main conveyor belt.

[0029] Specifically, a robot is used to absorb or clamp the buffer layer on the main conveyor belt and place it on the dispensing station of the dispensing machine or laminating machine. The CCD obtains the image of the buffer layer, and obtains the length a and width b of the buffer layer, sets the glue coating thickness h, and calculates the amount of glue Y. The calculation formula is Y=a*b*h. The dispensing machine or laminating machine pours Y amount of glue into the production box and evenly coats the glue on the buffer layer. After coating, it is left to stand for 5-10 minutes until the glue produces a visual sense of drawing on the buffer layer to ensure that the glue and the buffer layer have been solidified to a certain strength. After standing, the robot is used to push the buffer layer onto the main conveyor belt.

[0030] In a preferred embodiment of the present invention, the glue is resin, and the thickness h of the glue coating is in the range of 2 mm to 8 mm.

[0031] In a preferred embodiment of the present invention, the length a of the buffer layer is 250 mm, the width b is 300 mm, and the thickness h of the glue coating is 5 mm, then the glue coating amount Y=0.25*0.3*0.005m 2 =0.000375m2 .

[0032] S3, bonding: transfer the buffer layer from the main conveyor belt to the bonding station, identify the position of the buffer layer, set the bonding drawing of the bulletproof layer, and bond the bulletproof layer to the set position, and then return it to the main conveyor belt after completion.

[0033] Specifically, a manipulator is used to suck or clamp the buffer layer from the main conveyor belt and place it on the bonding station. The CCD obtains the image of the buffer layer and sets the bonding drawing of the bulletproof layer. The drawing at least includes the shape and position of the bulletproof layer. When the bulletproof layer is bonded, the logical formula is Zs=As*Ws+Bs*Vs+Cs*Xs, where Z is the number and shape code of the bulletproof layer; W, V, and X represent the codes of different bulletproof layers respectively. When W, V, or X is 1, it means that a bulletproof layer of this shape is required, and when it is 0, it means that a bulletproof layer of this shape is not required; A, B, and C represent the number of bulletproof layers of different shapes respectively, and s is the number of bonding rows. The manipulator bonds the bulletproof layer to the buffer layer in sequence according to the set drawing. After the bonding is completed, the manipulator is used to transport the bonded buffer layer and bulletproof layer to the main conveyor belt.

[0034] For example, when bonding the first row, s is 1. W, V, and X represent small rectangles, large rectangles, and triangles, respectively. Two W-shaped bulletproof layers and three V-shaped bulletproof layers are needed for bonding, so Z=2*1+3*1+0*0.

[0035] In a preferred embodiment of the present invention, the bulletproof layer is ceramic.

[0036] S4, verification: obtain the images of the buffer layer and the bulletproof layer after bonding, and verify whether the bonding of each bulletproof layer is qualified row by row according to the logic formula and sequence. If the bulletproof layer is qualified, it will be sent back to the main conveyor belt. If it is unqualified, the unqualified product will be removed from the production line.

[0037] When verifying, the pseudo code is:

[0038] If

[0039] z1=Z1,w1=W1,v1=V1,x1=X1,a1=A1,b1=B1,c1=C1 (z, w, v, x, a, b, c here are the first row of data recognized by CCD camera, and each row is compared with the set logic formula and sequence to confirm whether they are consistent. Different subscripts of z below represent different numbers of rows)

[0040] y2……

[0041] y3……

[0042] then

[0043] "qualified"

[0044] Else

[0045] "FAIL" and "WARNING"

[0046] That is, if the bonding inspection between the bulletproof layer and the buffer layer is normal, a "qualified" instruction is given and the product continues to be transported. If an abnormality is found, an "unqualified" and "WARNING" instruction is given, an alarm sounds, and the abnormal product is transported to the inspection area via a sub-conveyor belt. At the same time, the abnormal situation is fed back to the central control and handled by on-site staff.

[0047] S5, hemming: Take the buffer layer and bulletproof layer from the main conveyor belt to the hemming station and cover them with waterproof cover. The thickness of the waterproof cover shall not exceed 2cm. After the coating is completed, it will be transported back to the main conveyor belt.

[0048] S6, pressurized curing: the coated buffer layer and bulletproof layer are taken from the main conveyor belt to the pressing station, with a pressure of 5kg-10kg and a pressing time of 12-36 hours, and then returned to the main conveyor belt. After pressurized curing, it becomes a qualified bulletproof insert.

[0049] Specifically, a laminating machine is used for laminating. The laminating machine has 5-10 laminating stations, each of which accommodates 10-30 coated buffer layers and bulletproof layers. A pneumatic control method is used to generate a pressure of 5kg-10kg on the pressing plate, and the pressing is performed for 12-36 hours.

[0050] The pseudo code of the working logic of the press machine is:

[0051] If

[0052] L=10 (here L is the number of superimposed layers, here we take 10 layers as an example)

[0053] Then

[0054] "work"

[0055] Else

[0056] "waiting"

[0057] When the "work" command is given, the laminating machine opens the pneumatic valve and performs the laminating work. When the "waiting" command is given, the pneumatic valve does not open and continues to wait. After the laminating is completed, the conveyor belt sends the product to the printing station.

[0058] S7, Printing: Take the bulletproof insert plate to the screen printing station and print the specification information. After printing, the bulletproof insert plate is returned to the main conveyor belt.

[0059] S8, packaging, take the bulletproof insert to the packaging station for packaging, and after packaging, it is transported to the shelf by the conveyor belt.
