Description

Technical Field

[0001] The invention relates to the technical field of production of insulation cover and thermal insulation pad assemblies, and in particular to an automatic visual bonding production line for insulation cover and thermal insulation pads. Background Art

[0002] Insulation cover and thermal insulation pad assembly products play many roles in new energy vehicles and are widely used in the protection of key components inside automobiles. The demand for insulation cover and thermal insulation pad assembly products is growing, and traditional production processes are increasingly unable to meet customer needs, so it is necessary to develop new production lines to improve production efficiency.

[0003] Traditional production and processing technology:

[0004] (1) Die-cutting: Die-cut the semi-finished insulation cover sheet from the PC insulation film roll; manually transfer the semi-finished insulation cover sheet to the hot pressing process;

[0005] (2) Hot pressing: The hot pressing mold is heated by a hot pressing machine, and the die-cut insulation cover sheet semi-finished product is placed in the hot pressing mold. The insulation cover semi-finished product with a ballast structure is manufactured by the pressing action of the hot pressing mold and the heat transferred from the hot pressing mold; the insulation cover semi-finished product is manually transferred to the bending process;

[0006] (3) Bending: The bending die is installed on a pneumatic punch press, and the semi-finished insulation cover with a baffle structure is placed in the bending area of ​​the debending die. The finished insulation cover with an L-shaped bent end is obtained by stamping the "V"-shaped punch and the "V"-shaped sink groove of the bending die; the finished insulation cover is manually transferred to the bonding process;

[0007] (4) Bonding: Use manual operation to bond the thermal insulation pad onto the finished insulation cover with bent ends.

[0008] Traditional production and processing technology has the following disadvantages:

[0009] 1. To process the semi-finished insulation cover sheet after die-cutting into the finished insulation cover with L-shaped bent end, it needs to go through two processes: hot pressing and bending. Due to the addition of the bending process, the processing efficiency is low and the processing cost is high. The corresponding mold also needs to be made of hot pressing mold and bending mold at the same time, which increases the cost of bending mold. When using the original bending mold and punching equipment for processing, it is impossible to heat and hold the pressure, the bending angle deviation is large, and the bending angle stability is relatively poor.

[0010] 2. The production efficiency is extremely low, as the insulation pads and insulation covers are manually attached one by one. Accordingly, additional staffing is required to deliver the products on time to meet customer order requirements. In addition, manually attaching insulation pads one by one is unstable, which easily increases the number of defective products. The high labor cost and unstable product quality easily lead to customer complaints, affecting the image of the production company.

[0011] 3. There are many processes, and the insulation cover and thermal insulation pad assemblies need to go through multiple processes to produce and process. Continuous processing cannot be achieved between various equipment, and the material transfer work needs to be completed manually, which is not conducive to the full automation transformation of the production model.

[0012] Therefore, how to automatically transport the insulation cover material, perform hot pressing and bending operations on the same equipment, automatically fit the insulation cover and the insulation pad, and improve the production efficiency of the insulation cover and insulation pad assembly is a technical problem that needs to be solved urgently in this field. Summary of the invention

[0013] The technical problem to be solved by the present invention is to provide an automated visual bonding production line for insulation covers and thermal insulation pads, automatically transport insulation cover materials, perform hot pressing and bending operations on the same equipment, automatically bond insulation covers and thermal insulation pads, and improve the production efficiency of insulation cover and thermal insulation pad assemblies.

[0016] The die-cutting machine is used to die-cut the insulating film to obtain the semi-finished insulating cover sheet material, and the semi-finished insulating cover sheet material enters the manipulator loading and unloading hot pressing molding machine;

[0017] The manipulator loading and unloading hot press molding machine comprises a first transport device, a loading manipulator, a hot press bending and molding device, a unloading manipulator and a second transport device, the manipulator loading and unloading hot press molding machine is used to transport the insulating cover sheet semi-finished product to the transport area of ​​the loading manipulator through the first transport device, the loading manipulator transports the insulating cover sheet semi-finished product from the first transport device to the hot press bending and molding device, the hot press bending and molding device presses the insulating cover sheet semi-finished product into an insulating cover finished product with a bent end, the unloading manipulator transports the insulating cover finished product from the hot press bending and molding device to the second transport device, and the second transport device transports the insulating cover finished product to the visual bonding machine;

When the release paper tearing device clamps the release paper of the thermal insulation pad semi-finished product, the thermal insulation pad transfer device transfers the thermal insulation pad semi-finished product from the thermal insulation pad conveying device. The release paper of the double-sided tape is torn off and the thermal insulation pad semi-finished product becomes a finished thermal insulation pad. The thermal insulation pad transfer device then transfers the finished thermal insulation pad to the shooting area of ​​the insulation cover insulation pad bonding camera and places it on the upper surface of the insulation cover finished product. The finished thermal insulation pad is bonded with the insulation cover finished product to obtain an insulation cover insulation pad assembly. The assembly unloading and handling device takes away the insulation cover insulation pad assembly.

[0019] Compared with the background technology, the advantages and beneficial effects of the present invention are:

[0051] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] See also Figures 1 to 25 , a preferred embodiment of the present invention.

[0053] An automatic visual bonding production line for insulation covers and thermal insulation pads, comprising:

[0054] Die-cutting machine 1, robot loading and unloading hot pressing machine 2 and visual laminating machine 3;

[0055] The die-cutting machine 1 is used to die-cut the insulating film 4 to obtain the insulating cover sheet semi-finished product 41, and the insulating cover sheet semi-finished product 41 enters the manipulator loading and unloading hot pressing molding machine 2;

[0056] The manipulator loading and unloading hot press molding machine 2 comprises a first transport device 21, a loading manipulator 22, a hot press bending and molding device 23, a unloading manipulator 24 and a second transport device 25. The manipulator loading and unloading hot press molding machine is used to transport the insulating cover sheet semi-finished product 41 to the transporting area of ​​the loading manipulator 22 through the first transport device 21. The loading manipulator 22 transports the insulating cover sheet semi-finished product 41 from the first transport device 21 to the hot press bending and molding device 23. The hot press bending and molding device 23 presses the insulating cover sheet semi-finished product 41 into an insulating cover finished product 42 with a bent end 421. The unloading manipulator 24 transports the insulating cover finished product 42 from the hot press bending and molding device 23 to the second transport device 25. The second transport device 25 transports the insulating cover finished product 42 to the visual bonding machine 3.

[0057] The visual bonding machine 3 includes an insulation cover feeding and conveying device 31, an insulation cover conveying device 32, an insulation cover positioning camera 33, an insulation cover thermal insulation pad bonding camera 34, an insulation pad supplying device 35, an insulation pad feeding and conveying device 36, an insulation pad conveying device 37, an insulation pad positioning camera 38, a release paper tearing device 39, an insulation pad transferring device 310 and an assembly discharging and conveying device 320. The visual bonding machine is used to place the insulation cover finished product 42 on the insulation cover conveying device 32 through the insulation cover feeding and conveying device 31, the insulation cover conveying device 32 conveys the insulation cover finished product 42 to the shooting area of ​​the insulation cover positioning camera 33 and the insulation cover thermal insulation pad bonding camera 34 in sequence, the insulation pad supplying device 35 provides the insulation pad semi-finished product 5, the insulation pad semi-finished product 5 is affixed with double-sided tape, and the insulation pad feeding and conveying device 36 transfers the insulation pad semi-finished product 5 The semi-finished insulation pad 5 is transported to the insulation pad conveying device 37, and the insulation pad conveying device 37 conveys the semi-finished insulation pad 5 to the shooting area of ​​the insulation pad positioning camera 38 and the release paper tearing device 39 in sequence. When the release paper tearing device 39 clamps the release paper 51 of the semi-finished insulation pad 5, the insulation pad transfer device 310 transfers the semi-finished insulation pad 5 from the insulation pad conveying device. The release paper 51 of the double-sided tape is torn off and the semi-finished insulation pad 5 becomes a finished insulation pad 52. The insulation pad transfer device 310 then transfers the finished insulation pad 52 to the shooting area of ​​the insulation cover insulation pad bonding camera 34, and places it on the upper surface of the insulation cover finished product 42. The finished insulation pad 52 is bonded with the insulation cover finished product 42 to obtain an insulation cover insulation pad assembly 6, and the assembly unloading and conveying device 320 takes away the insulation cover insulation pad assembly 6.

[0058] The beneficial effect of the above technical scheme is that the die-cutting machine 1, the robot loading and unloading hot pressing molding machine 2 and the visual bonding machine 3 are arranged in an assembly line, the insulating cover sheet semi-finished product 41 coming out of the die-cutting machine 1 enters the robot loading and unloading hot pressing molding machine 2, the robot loading and unloading hot pressing molding machine 2 automatically transports the insulating cover sheet semi-finished product 41, and the insulating cover sheet semi-finished product 41 is subjected to hot pressing and bending operations in the hot pressing and bending molding device 23 to obtain an insulating cover finished product 42 with a bent end 421, and the insulating cover finished product 42 is automatically transported to the visual bonding machine 3, and the visual bonding machine 3 automatically bonds the insulating cover and the thermal insulation pad, thereby improving the production efficiency of the insulating cover and thermal insulation pad assembly 6.

[0059] The first transport device 21 and the second transport device 25 are both belt conveyors. The loading robot 22 and the unloading robot 24 both have a suction cup structure; the loading robot 22 handling area is provided with a first sensor 221 for detecting the semi-finished insulation cover sheet material. When the first sensor 221 detects the semi-finished insulation cover sheet material, the first sensor 221 sends a detection signal to the control device of the robot loading and unloading hot pressing molding machine 2. The control device first sends a stop signal to the first transport device 21 to stop the movement of the semi-finished insulation cover sheet material, and then sends a handling signal to the loading robot 22. The loading robot 22 sucks the semi-finished insulation cover sheet material and then transports it to the hot pressing bending molding device 23, and finally releases the semi-finished insulation cover sheet material. After the hot pressing and bending forming device 23 completes the hot pressing and bending operations, the unloading robot 24 sucks the finished insulation cover 42 and then transports it to the second transport device 25. The transport area of ​​the unloading robot 24 is provided with a second sensor 241 for detecting the stacking height of the finished insulation cover 42. When the second sensor 241 does not detect the finished insulation cover 42, the control device stops the second transport device 25 from moving, and the unloading robot 24 stacks the finished insulation cover 42 on the second transport device 25. When the finished insulation cover 42 is stacked to a specified height, the second sensor 241 detects the finished insulation cover 42, and the second sensor 241 sends a detection signal to the control device, which sends a stepping signal to the second transport device 25, and the second transport device 25 moves forward a stacking area distance. The finished insulation cover 42 is stacked in groups and enters the visual bonding machine 3.

[0060] The insulation cover feeding and conveying device 31, the insulation pad feeding and conveying device 36, the insulation pad transfer device 310 and the assembly discharging and conveying device 320 all use manipulators equipped with suction cups, wherein the insulation pad transfer device 310 can also be replaced with a four-axis robot. The insulation cover conveying device 32 and the insulation pad conveying device 37 both use belt conveyors. Double-sided tape is obtained by bonding release paper and glue to each other.

[0061] The camera 33 for positioning the insulation cover, the camera 34 for fitting the insulation cover and the camera 38 for positioning the insulation cover are all first used with industrial vision cameras; the camera 33 for positioning the insulation cover and the camera 34 for fitting the insulation cover and the insulation cover are both above the insulation cover conveying device 32, the camera 33 for positioning the insulation cover is used to detect whether the position of the finished insulation cover 42 on the insulation cover conveying device 32 is normal, the camera 34 for fitting the insulation cover and the insulation cover is used to detect whether the finished insulation cover 42 and the finished insulation cover 52 are in a normal fitting position; the camera 38 for positioning the insulation cover is above the insulation cover conveying device 37, the camera 38 for positioning the insulation cover is used to detect whether the semi-finished insulation cover 5 is in the release paper 51 tearing position, which helps to cooperate with the release paper tearing device 39 and the insulation cover transfer device 310.

[0062] Furthermore, the thermal insulation pad supply device 35 includes a base 351, a material bin 352, a lifting plate 353, a slide plate 354 and a material pushing drive mechanism 356. The lower end of the material bin 352 is fixedly set on the base 351, and a material taking port 3521 is provided at the upper end of the material bin 352. The lifting plate 353 is slidably set inside the material bin 352. A guide hole 3522 is provided on the side wall of the material bin 352. The slide plate 354 passes through the guide hole 3522, and the material pushing drive mechanism 356 is connected to the lifting plate 353 through the slide plate 354.

[0063] The beneficial effect of this technical solution is that the semi-finished insulation pads 5 are stacked and placed on the lifting plate 353, and the lifting drive mechanism 356 causes the lifting plate 353 to rise gradually, so that the semi-finished insulation pads 5 emerge one by one from the material bin 352's material port 352, making it convenient to cooperate with the thermal insulation pad feeding and handling device 36 to take out the semi-finished insulation pads 5 from the material bin 352 one by one, and the semi-finished insulation pads 5 are placed one by one at the entrance of the thermal insulation pad conveying device 37, and the thermal insulation pad conveying device 37 conveys the semi-finished insulation pads 5 in a step-by-step manner.

[0064] Furthermore, the visual bonding machine 3 also includes an insulating cover supply device 330, and the structure of the insulating cover supply device 330 is the same as that of the thermal insulation pad supply device 35. The insulating cover feeding and conveying device 31 includes a feeding support 311, a lifting drive cylinder 312, a support block 313, a rotating drive cylinder 314, a rotary arm 315, a first suction cup 316 and a second suction cup 317. The lifting drive cylinder 312 is fixedly arranged on the feeding support 311, the support block 313 is fixedly arranged on the lifting end of the lifting drive cylinder 312, the rotating drive cylinder 314 is fixedly arranged on the support block 313, and the middle part of the rotary arm 315 is fixedly arranged on the rotating end of the rotating drive cylinder 314. The first suction cup 316 and the second suction cup 317 are respectively fixedly arranged at the two ends of the rotary arm 315, and the two ends of the rotary arm 315 are respectively aligned downward with the material taking port 3521 of the insulating cover supply device 330 and the entrance of the insulating cover conveying device 32.

[0065] The beneficial effect of this technical solution is that when the stacked insulation cover finished products 42 arrive at the exit of the second transportation device 25, the stacked insulation cover finished products 42 are manually placed into the material bin 352 of the insulation cover supply device 330, thereby improving the loading efficiency of the insulation cover finished products 42; with the cooperation of the lifting drive cylinder 312 and the rotating drive cylinder 314 of the insulation cover feeding and conveying device 31, the first suction cup 316 sucks down the insulation cover finished products 42 located at the material taking port 3521 of the insulation cover supply device 330, and the first suction cup 316 rises again, rotates 180° to reach above the entrance of the insulation cover conveying device 32, and the first suction cup 316 descends again to release the insulation cover finished products 42, and the insulation cover finished products 42 fall at the entrance of the insulation cover conveying device 32, and at this time, the second suction cup 317 is aligned with the material taking port 3521 of the insulation cover supply device 330, and the cycle is operated in this way, thereby improving the loading efficiency of the insulation cover finished products 42. This is one embodiment of the present invention; in another embodiment, the insulating cover feeding and conveying device 31 can directly convey the insulating cover finished product 42 from the outlet of the second conveying device 25 to the inlet of the insulating cover conveying device 32.

[0066] Furthermore, the visual bonding machine 3 also includes an insulating cover guide device 340, and the insulating cover guide device 340 includes a left guide plate 3401, a right guide plate 3402, a bridging plate 3403 and a spacing adjustment cylinder 3404. The spacing adjustment cylinder 3404 is fixedly connected to the left side of the conveying belt of the insulating cover conveying device 32 through the bridging plate 3403. The left guide plate 3401 is fixedly arranged at the telescopic end of the spacing adjustment cylinder 2404, and the right guide plate 3402 is fixedly connected to the right side of the conveying belt of the insulating cover conveying device 32. There is a gap between the right guide plate 3402 and the conveying belt of the insulating cover conveying device 32, and the right guide plate 3402 has an inclined surface at the lower left and upper right.

[0067] The beneficial effect of this technical solution is that the spacing adjustment cylinder 3404 is used to adjust the spacing between the left guide plate 3401 and the right guide plate 3402 according to actual production conditions; when the insulation cover feeding and conveying device 31 releases the insulation cover finished product 42, the insulation cover finished product 42 falls between the left guide plate 3401 and the right guide plate 3402, and the bent end 421 of the insulation cover finished product 42 enters the gap along the inclined surface of the right guide plate 3402, which helps to make the fitting surface of the insulation cover horizontal, thereby improving the fitting efficiency of the insulation cover and the thermal insulation pad.

[0068] Furthermore, the visual bonding machine 3 also includes a defective product rejection device 350, and the defective product rejection device 350 is adjacent to the insulation cover conveying device 32. When the insulation cover thermal insulation pad bonding camera 34 recognizes that the bonding position of the insulation cover thermal insulation pad assembly 6 is poor, the insulation cover thermal insulation pad bonding camera 34 sends a rejection signal to the defective product rejection device 350, and the defective product rejection device 350 rejects the insulation cover thermal insulation pad assembly 6 from the shooting area of ​​the insulation cover thermal insulation pad bonding camera 34.
