Description

Technical Field

[0001] The invention relates to the technical field of insulating cover manufacturing, and in particular to an insulating cover manufacturing device and a manufacturing method. Background Art

[0002] In new energy vehicles, the main function of the insulation cover assembly is to ensure the safety and reliability of the electrical system. During the manufacturing process, the insulation cover needs to go through the processes of blister heating, cutting, hot pressing and gluing in sequence. Among them, the blister heating process requires heating and cooling, which results in a long processing line. At the same time, the insulation cover is manually pasted during the gluing process, which makes it impossible to achieve continuous processing between equipment, which is not conducive to the full automation transformation of the production model; and the manual tape pasting has limited pasting accuracy, which is very likely to increase the production of defective products. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an insulating cover manufacturing device and a manufacturing method, which can optimize the production line of the insulating cover.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: an insulating cover manufacturing device, comprising a first conveyor belt, a heater and a cooler; the transmission surface of the first conveyor belt has a molding station, a blister mold is provided below the molding station in a lifting manner, the heater has a heating end that moves above the molding station, and the cooler is arranged above the first conveyor belt.

[0005] Another technical solution adopted by the present invention is: a manufacturing method, after the PC insulation film is heated by vacuum forming, a semi-finished insulation cover is obtained; The insulating cover semi-finished product is cut and then hot-pressed to obtain an insulating cover; The insulating cover has a first end face and a second end face along its thickness direction, and position information of the first end face and the second end face are respectively obtained, and tape is pasted on the first end face according to the position information of the first end face, and tape is pasted on the second end face according to the position information of the second end face.

[0006] The beneficial effects of the present invention are as follows: after the PC insulating film is located at the forming station of the first conveyor belt, the PC insulating film is fixed by the blister mold, and at the same time, the heating end of the heater is close to the forming station to heat the PC insulating film so that the PC insulating film can be formed on the blister mold to obtain the semi-finished insulating cover; after the heating is completed, the heating end of the heater is away from the forming station, and the cooler is operated to reduce the temperature of the semi-finished insulating cover so that the semi-finished insulating cover can be demolded from the blister mold. Then the demolded insulating cover semi-finished product is output from the first conveyor belt to the next process. During the entire blister heating process, the first conveyor belt does not need to be used to transport the PC insulating film, thereby shortening the length of the blister heating process line.

[0007] During the gluing process of the insulation cover, by obtaining the position information of the first end face and the second end face of the insulation cover and the position information of the tape, the mechanical equipment can accurately stick the tape on the first end face and the second end face of the insulation cover according to the obtained position information.

DETAILED DESCRIPTION

[0009] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0010] Please refer to Figure 1 and Figure 2 As shown, an insulating cover manufacturing device of the present invention includes a first conveyor belt 1, a heater 2 and a cooler 3; the transmission surface of the first conveyor belt 1 has a molding station, a blister mold 4 is provided below the molding station in a lifting manner, the heater 2 has a heating end that moves to above the molding station, and the cooler 3 is arranged above the first conveyor belt 1.

[0011] Working principle: After the PC insulating film is pulled out from the discharge roller and placed on the forming station of the first conveyor belt 1, the blister mold 4 rises and absorbs the PC insulating film, and then the heating end of the heater 2 is close to the forming station to heat the PC insulating film so that the PC insulating film can be formed on the blister mold 4 to obtain the semi-finished insulating cover; after the heating is completed, the heating end of the heater 2 is away from the forming station, and the cooler 3 is operated to reduce the temperature of the semi-finished insulating cover so that the semi-finished insulating cover can be demoulded from the blister mold 4. Then the demoulded insulating cover semi-finished product enters the next process from the first conveyor belt output 1. During the entire blister heating process, the first conveyor belt does not need to be used to transport the PC insulating film, thereby shortening the length of the blister heating process line.

[0012] It is worth noting that the cooler 3 preferably adopts a blower, which blows air toward the forming station.

[0013] In some embodiments, the conveyor belt of the first conveyor belt output 1 has a plurality of teeth (not shown in the figure), and the teeth are used to hook the edge of the PC insulating film to realize the conveyance of the PC insulating film.

[0014] In some embodiments, see Figure 2 As shown, the heater 2 includes a first slide rail 21 and a heating unit 22. The length direction of the first slide rail 21 is perpendicular to the transmission direction of the first conveyor belt 1. The heating unit 22 is slidably arranged on the first slide rail 21. The heating unit 22 moves closer to and away from the forming station by moving on the first slide rail 21. The driving force for the heating unit 22 to move on the first slide rail 21 can be driven by a driving component such as a cylinder, an oil cylinder, or a motor.

[0015] In some embodiments, the heating unit 22 includes a mounting frame and a plurality of electric ceramic plates mounted on the mounting frame. The mounting frame is slidably disposed on the first slide rail 21, and the electric ceramic plates heat the PC insulating film by heat radiation. The number of electric ceramic plates on the mounting frame is determined according to the area of ​​the PC insulating film located on the forming station.

[0016] In some embodiments, see Figure 2 and Figure 3As shown, the discharge end of the first conveyor belt 1 is provided with a cutting tool 5 and a first transfer device 6; the first transfer device 6 includes a second conveyor belt 61 and a clamp 62, and the clamp 62 has a clamping end that reciprocates between the discharge end of the first conveyor belt 1 and the feed end of the second conveyor belt 61. After the PC insulating film is formed into a semi-finished insulating cover by vacuum forming and heating, the semi-finished insulating cover is clamped by the clamp 62, and cooperates with the first conveyor belt 1 to pull the semi-finished insulating cover out of the first conveyor belt 1, and at the same time pull the PC insulating film on the discharge roller into the forming station, and then the PC insulating film is separated from the semi-finished insulating cover by the cutting tool 5, and finally the clamp 62 places the separated semi-finished insulating cover on the second conveyor belt 61 for the next process.

[0017] In certain embodiments, see Figure 3 As shown, the cutting tool 5 includes a third slide rail 51 and a blade 52 slidably arranged on the third slide rail 51, and the projection of the third slide rail 51 on the first conveyor belt 1 is perpendicular to the transmission direction of the first conveyor belt 1. The separation of the PC insulating film and the insulating cover semi-finished product is achieved by moving the blade 52. The driving force for the blade 52 to move on the third slide rail 51 can be driven by a driving component such as a cylinder, an oil cylinder, or a motor.

[0018] In some embodiments, the cutting tool 5 may also be a cutter moving in the vertical direction.

[0019] In certain embodiments, see Figure 3 and Figure 4 As shown, the clamp 62 includes a second slide rail 621 and a clamp 622, and the clamp 622 is slidably disposed on the second slide rail 621. The clamp 622 moves on the second slide rail 621 to grasp the semi-finished insulation cover, and transfers the semi-finished insulation cover to the feed end of the second conveyor belt 61. The driving force for the clamp 622 to move on the second slide rail 621 can be driven by a driving component such as a cylinder, an oil cylinder, or a motor.

[0020] In certain embodiments, see Figure 4 As shown, the clamp 62 further includes a lifter 623, and the clamping jaw 622 is connected to the movable end of the lifter 623. The clamping height of the clamping jaw 622 is controlled by the lifter 623, so as to place the semi-finished insulation cover on the feeding end of the second conveyor belt 61.

[0021] In certain embodiments, see Figure 1As shown, an insulating cover manufacturing device also includes a cutting component 7, which includes a material plate 71, a cutting machine 72 and a fourth manipulator 73. The cutting machine 72 has a cutting inner cavity and a material preparation station, and a cutting die is provided in the cutting inner cavity. The material plate 71 reciprocates between the material preparation station and the cutting inner cavity. The fourth manipulator 73 is used to transfer the semi-finished insulating cover at the discharge end of the second conveyor belt 61 to the material plate 71, and to transfer the semi-finished insulating cover on the material plate 71 to the next process. Since the PC insulating film is heated by vacuum forming, multiple pieces of semi-finished insulating cover connected together are obtained. The whole piece of semi-finished insulating cover is sent into the cutting inner cavity of the cutting machine 72 through the material plate 71, and the cutting machine 72 cuts the whole piece of semi-finished insulating cover into multiple pieces of semi-finished insulating cover. The material plate 71 then transfers the semi-finished insulating cover cut into multiple pieces to the material preparation station, and finally the fourth manipulator 73 transfers them one by one to the next process.

[0022] It is worth noting that in order to reduce the complexity of the execution procedure of the fourth manipulator 73, the cutting assembly 7 can be equipped with two fourth manipulators 73. Specifically, the feed end and the discharge end of the material preparation station are respectively equipped with fourth manipulators 73, and the fourth manipulator 73 at the feed end of the material preparation station has a grabbing end that reciprocates between the discharge end of the second conveyor belt 61 and the material plate 71. The fourth manipulator 73 at the feed end of the material preparation station grabs the entire piece of the semi-finished insulation cover at the discharge end of the second conveyor belt 61, and transfers and places it on the material plate 71, and then the material plate 71 sends the entire piece of the semi-finished insulation cover into the cutting inner cavity of the cutting machine 72 for cutting, so that each piece of the semi-finished insulation cover is separated, and then separated into several pieces of semi-finished insulation cover, and then sent back to the material preparation station due to the material plate 71, and finally transferred one by one to the next process by the fourth manipulator 73 at the discharge end of the material preparation station.

[0023] In some embodiments, a material sensor is provided at the discharge end of the second conveyor belt 61. The material sensor determines whether there is an insulating cover semi-finished product at the discharge end of the second conveyor belt 61, thereby facilitating the control of the operation timing of the fourth manipulator 73.

The semi-finished insulating cover is hot-pressed by the hot press machine 82 to obtain the insulating cover 100 of the desired shape.

[0025] It is worth noting that, in order to increase the complexity of the execution procedure of the fifth manipulator 83, the hot pressing assembly 8 can be equipped with two fifth manipulators 83. Specifically, one of the fifth manipulators 83 is used to place the semi-finished insulation cover at the discharge end of the third conveyor belt 81 into the hot pressing mold of the hot pressing machine 82, and the other fifth manipulator 83 is used to transfer the hot-pressed insulation cover 100 to the next process.

[0026] In some embodiments, a material sensor is provided at the discharge end of the third conveyor belt 81. The material sensor determines whether there is an insulating cover semi-finished product at the discharge end of the third conveyor belt 81, thereby facilitating the control of the operation timing of the fifth manipulator 83.

[0027] In certain embodiments, see Figure 1 , Figure 5 and Figure 6 As shown, in the production process of the insulating cover 100, a small adhesive tape needs to be pasted on the second end surface 102 of the insulating cover 100. Therefore, an insulating cover manufacturing device also includes a glue sticking component 9, and the glue sticking component 9 includes a first positioning fixture 91 and a first manipulator 92; a first camera 911 is provided at the side end of the first positioning fixture 91, and a second camera 912 is provided above the first positioning fixture; the first manipulator 92 is located at the side end of the first positioning fixture 91, and the grasping end of the first manipulator 92 passes above the first camera 911. The insulating cover 100 is positioned and placed on the first positioning fixture 91, and the second end surface 102 of the insulating cover 100 is exposed under the second camera 912, and the second camera 912 obtains the image information of the second end surface 102 of the insulating cover 100. At the same time, the first manipulator 92 grabs the small tape and carries the small tape over the first camera 911, and the first camera 911 obtains the image information of the small tape on the first manipulator 92. The first manipulator 92 can accurately stick the small tape on the second end surface 102 of the insulating cover 100 based on the image information obtained by the first camera 911 and the second camera 912.

[0028] In certain embodiments, see Figure 7As shown, the first manipulator 92 includes a first reciprocating device 921, a second reciprocating device 922 and a third reciprocating device 923; the first reciprocating device 921 has a movable end that moves in the horizontal direction, the second reciprocating device 922 is connected to the movable end of the first reciprocating device 921, the second reciprocating device 922 has a movable end that moves in the horizontal direction, and the moving direction of the movable end of the second reciprocating device 922 is perpendicular to the moving direction of the movable end of the first reciprocating device 921, the third reciprocating device 923 is connected to the movable end of the second reciprocating device 922, the third reciprocating device 923 has a movable end that moves in the vertical direction, and a suction cup is provided on the movable end of the third reciprocating device 923. The first reciprocating device 921, the second reciprocating device 922 and the third reciprocating device 923 cooperate to realize that the first manipulator 92 obtains the tape from the corresponding glue barrel and then sticks the tape on the second end surface 102 of the insulating cover 100.

[0029] In some embodiments, see Figure 5 , Figure 6 and Figure 8 As shown, in the production process of the insulating cover 100, a large-surface adhesive tape needs to be pasted on the first end surface 101 of the insulating cover 100. Therefore, the adhesive assembly 9 also includes a flipper 93, a second positioning fixture 94 and a second manipulator 95. The flipper 93 has a gripping end that flips back and forth between the first positioning fixture 91 and the second positioning fixture 94; a third camera 941 is provided at the side end of the second positioning fixture 94, and a fourth camera 942 is provided above the first positioning fixture; the second manipulator 95 is located at the side end of the second positioning fixture 94, and the gripping end of the second manipulator 95 passes above the third camera 941.

The fourth camera 942 obtains the image information of the first end surface 101 of the insulating cover 100. The second manipulator 95 grabs the large-surface tape and carries the large-surface tape over the third camera 941. The third camera 941 obtains the image information of the large-surface tape on the second manipulator 95. The second manipulator 95 can accurately stick the large-surface tape on the first end surface 101 of the insulating cover 100 based on the image information obtained by the third camera 941 and the fourth camera 942.

[0030] In some embodiments, see Figure 8As shown, the flipper 93 includes a motor 931 and a first suction cup 932; the first suction cup 932 is connected to the output shaft of the motor 931, so that the first suction cup 932 is flipped between the first positioning fixture 91 and the second positioning fixture 94. The motor 931 drives the first suction cup 932 to swing to the first positioning fixture 91, so that the insulation cover 100 can be adsorbed, and then the motor 931 drives the first suction cup 932 to swing, so that the insulation cover 100 can be turned over and transferred to the second positioning fixture 94.

[0031] In certain embodiments, see Fig. 9 As shown, the second manipulator 95 adopts a six-axis robot. The end effector of the second manipulator 95 is provided with a second suction cup 951 and a pressure roller 952 rotatably arranged on one side of the second suction cup 951. After the second manipulator 95 moves the second suction cup 951 to obtain the large-surface adhesive tape from the corresponding glue barrel, the large-surface adhesive tape is pasted on the first end face 101 of the insulating cover 100. At the same time, the pressure roller 952 is used to roll the large-surface adhesive tape pasted on the first end face 101 to ensure the pasting quality of the large-surface adhesive tape.
