[0037] The PTC ceramic heating sheet automatic code disc device has the advantages that:

[0038] As Figures 1-7 ​​​​The utility model provides a kind of automatic tray device for PTC ceramic heating sheet, it includes heating sheet conveyor 100, copper tray conveyor 200 and tray mechanical hand 300.

[0039] Heating sheet conveyor 100 transmits PTC ceramic heating sheet 800 along horizontal direction, and first designated area 1a is arranged at its predetermined position.PTC ceramic heating sheet 800 is linearly queued and stops at first designated area 1a as the moving end point on heating sheet conveyor 100, see Figure 2 .

[0040] Copper tray conveyor 200 transmits copper tray 900 along horizontal direction, and second designated area 2a is arranged at its predetermined position.Second designated area 2a is the temporary stop area of copper tray 900 moving on copper tray conveyor 200, see Figure 4 .

[0041] Tray mechanical hand 300 is configured to grab PTC ceramic heating sheet 800 stopping at first designated area 1a, and then transfer and place it on copper tray 900 stopping at second designated area 2a.Moreover, tray mechanical hand 300 grabs at least two PTC ceramic heating sheets 800 at a time, and then transfers and places them in the pre-set groove hole 910 on the surface of copper tray 900, which matches the shape of PTC ceramic heating sheet 800.

[0042] As shown in Figure 2 , the belt body of heating sheet conveyor 100 is first belt body 150, the width of first belt body 150 is relatively narrow, slightly larger than the width of PTC ceramic heating sheet 800, and two sides are provided with baffle 140.During conveying, the length direction of PTC ceramic heating sheet 800 is consistent with the extension direction of first belt body 150, and the width of first belt body 150 limits PTC ceramic heating sheet 800 to be arranged in single column, and cannot be arranged side by side.Typically, as shown in Figure 2 , heating sheet conveyor 100 can include two or even more parallel first belt bodies 150 to improve transmission efficiency.

[0043] As shown in Figure 4 , copper tray conveyor 200 includes two parallel second belt bodies 220, and copper tray 900 is transversely arranged on the two second belt bodies 220.Moreover, the groove hole 910 of copper tray 900 on copper tray conveyor 200 is consistent with the attitude angle of PTC ceramic heating sheet 800 on heating sheet conveyor 100, that is, the length and width directions of the two are consistent.This consistency makes tray mechanical hand 300 transfer PTC ceramic heating sheet 800 without angle adjustment, which only needs to be grabbed from first designated area 1a, moved to the upper side of copper tray 900 in second designated area 2a along a reasonable path, and then released downward, without angle adjustment of PTC ceramic heating sheet 800 due to the difference in attitude angle between groove hole 910 and PTC ceramic heating sheet 800.

[0044] Generally, as shown in Figure 1 , the first designated area 1a is equipped with a first positioning device 110, which is used to limit the moving end point of the PTC ceramic heating sheet 800, forcing it to stay in linear formation in the first designated area 1a.

[0045] Specifically, as shown in Figure 2 , the first positioning device 110 is arranged at the front end of the first designated area 1a, and is fixed with the frame of the heating sheet conveying belt 100. The bottom of the first positioning device 110 is provided with a protruding part 111, which extends from top to bottom to close to the upper surface of the heating sheet conveying belt 100, and forms a block by contacting the PTC ceramic heating sheet 800 at the front end, so that several PTC ceramic heating sheets 800 stay in linear formation in the first designated area 1a.

[0046] Referring to Figure 2 , it should be noted that the lower surface of the protruding part 111 needs to be lower than the upper surface of the PTC ceramic heating sheet 800, and at the same time, there is a gap between the protruding part 111 and the first belt body 150 of the heating sheet conveying belt 100, so as to ensure that the protruding part 111 can form a block to the PTC ceramic heating sheet 800, and will not press the first belt body 150 below, avoiding affecting its normal operation.

[0047] Further, referring to Figure 2 , the first designated area 1a is also equipped with a pressing plate 120 and a third cylinder 130. The pressing plate 120 is arranged at the rear end of the first designated area 1a, and the bottom of the pressing plate 120 is provided with a protruding pressing block 121. The third cylinder 130 is fixed with the frame of the heating sheet conveying belt 100, and the piston rod of the third cylinder 130 is connected with the pressing plate 120, which is used to drive the pressing plate 120 to move vertically, so as to press or release the PTC ceramic heating sheet 800 below by the protruding pressing block 121.

[0048] Figure 2 As shown in the middle, the distance between the pressing plate 120 and the first positioning device 110 is slightly larger than the sum of the lengths of four PTC ceramic heating sheets 800, which can allow four PTC ceramic heating sheets 800 to be arranged on a single first belt body 150 in the first designated area 1a. The code disc mechanical hand 300 can grab these four PTC ceramic heating sheets 800 at the same time each time.

[0049] Among them, the number of protruding parts 111 of the first positioning device 110 matches the number of first belt bodies 150, and the number of protruding pressing blocks 121 of the pressing plate 120 also matches the number of first belt bodies 150. That is, if there are two first belt bodies 150, then the number of protruding parts 111 and protruding pressing blocks 121 is also two, and corresponds to the two first belt bodies 150 respectively.

[0050] During the working process, when the code disc mechanical hand 300 picks up the PTC ceramic heating sheet 800 staying in the first designated area 1a, the third cylinder 130 will drive the pressing plate 120 to move downward in advance, so that the protruding pressing block 121 will press the PTC ceramic heating sheet 800 (i.e. the fifth PTC ceramic heating sheet 800 from front to back in the figure) below, avoiding the situation that when the code disc mechanical hand 300 picks up the first four PTC ceramic heating sheets 800, the adjacent fifth PTC ceramic heating sheet 800 is driven to be dislocated.

[0051] Generally, as shown in Figure 3 and Figure 4 , the second designated area 2a is provided with a second positioning device 210 for clamping and stabilizing the copper disc 900 staying in the second designated area 2a.

[0052] Specifically, as shown in Figure 5 , the second positioning device 210 includes two clamping blocks 211, a first cylinder 212 and a second cylinder 213. The two clamping blocks 211 are located between the two second belt bodies 220 of the copper disc conveying belt 200, and are oppositely and spacedly arranged along the conveying direction of the copper disc conveying belt 200. The first cylinder 212 is a double-piston-rod cylinder, which is arranged between the two clamping blocks 211, and its two piston rods are respectively connected with the two clamping blocks 211, for driving the two clamping blocks 211 to move towards or away from each other, so as to clamp or release the clamping of the copper disc 900 staying in the second designated area 2a. The piston rod of the second cylinder 213 is connected with the first cylinder 212, for driving the first cylinder 212 to move vertically, so that the clamping block 211 is below or above the copper disc 900 staying in the second designated area 2a.

[0053] Further, as shown in Figure 5 , the bottom of the first cylinder 212 is fixed on a mounting seat 214. The second cylinder 213 is located below the first cylinder 212 and is fixed on a corresponding mounting frame 215. The piston rod of the second cylinder 213 vertically extends and is connected with the bottom of the mounting seat 214, for driving the mounting seat 214 to move vertically.

[0054] When the copper disc conveying belt 200 transports the copper disc 900 between the two clamping blocks 211, the copper disc conveying belt 200 is paused; then, the second air cylinder 213 works to push the mounting seat 214 to move upwards, so that the two clamping blocks 211 are respectively located on both sides of the copper disc 900; then, the first air cylinder 212 works to move the two clamping blocks 211 towards each other to clamp the copper disc 900; then, the code disc mechanical arm 300 can grab the PTC ceramic heating sheet 800 staying in the first specified area 1a and then transfer it to the slot hole 910 of the copper disc 900; after all the slot holes 910 of the copper disc 900 are filled with the PTC ceramic heating sheet 800, the first air cylinder 212 works reversely to move the two clamping blocks 211 away from each other to release the copper disc 900, and then the second air cylinder 213 works reversely to make the two clamping blocks 211 descend; then, the copper disc conveying belt 200 starts to run to transport the copper disc 900 to the subsequent process.

[0055] As shown in Figure 6 , the code disc mechanical arm 300 comprises an adsorption module 310, a lifting mechanism 320, a multi-axis motion module 330 and a variable distance module 340.

[0056] The adsorption module 310 is multiple and arranged equidistantly along the linear direction, and each adsorption module 310 corresponds to adsorb one PTC ceramic heating sheet 800. As shown in Figure 7 , the adsorption module 310 comprises a fixed block 312 and two suction nozzles 311, the fixed block 312 is installed on the variable distance module 340, the suction nozzles 311 are located at the bottom of the fixed block 312, and the two suction nozzles 311 are respectively used to adsorb the two ends of the PTC ceramic heating sheet 800 in the length direction of the upper surface. Generally, the number of adsorption modules 310 is greater than or equal to two and less than or equal to eight. In the example shown in the figure, the number of adsorption modules 310 is four.

[0057] The variable distance module 340 is a prior art device, which can be used to realize high-precision distance adjustment and is widely used in the fields of automation equipment, precision machinery and semiconductor manufacturing. When applied to the utility model, the variable distance module 340 drives each adsorption module 310 to move synchronously in the increasing or decreasing arrangement interval. The main structure of the variable distance module 340 includes a motor 341, a module shell 342 and a plurality of sliders 343. The motor 341 is installed beside the module shell 342, and the sliders 343 are installed at the bottom of the module shell 342. The sliders 343 are arranged at equal intervals along the linear direction. When the motor 341 works, it can drive the worm (not shown in the figure) inside the module shell 342 to rotate. The rotation of the worm drives the sliders 343 to move through the spiral track on the surface of the worm, so that the sliders 343 move synchronously in the increasing or decreasing arrangement interval. The fixed blocks 312 of the adsorption modules 310 are fixedly connected with the sliders 343. Therefore, when the motor 341 works, the movement of the sliders 343 drives the adsorption modules 310 to move synchronously in the increasing or decreasing arrangement interval, so as to realize the adjustment of the distance between the adsorption modules 310.

[0058] The lifting mechanism 320 is used to drive the variable distance module 340 and the adsorption module 310 to move vertically, so that the adsorption module 310 can move downward to be close to the PTC ceramic heating sheet 800 or move upward after releasing the PTC ceramic heating sheet 800. The lifting mechanism 320 can adopt a worm and gear lifting mechanism, which is a common lifting mechanism, so it is not shown in detail in the figure.

[0059] The multi-axis motion module 330 is used to drive the adsorption module 310 to move between above the first specified area 1a and above the second specified area 2a. As shown in the figure, the multi-axis motion module 330 includes a plurality of guide rails 331 and a plurality of guide wheels 332. The guide rails 331 are arranged on the first specified area 1a and the second specified area 2a, and the guide wheels 332 are arranged on the adsorption module 310. When the adsorption module 310 moves along the guide rails 331, the guide wheels 332 can move along the guide rails 331, so that the adsorption module 310 moves between above the first specified area 1a and above the second specified area 2a. Figure 6As shown, the multi-axis motion module 330 includes a fixed frame 331, a first motion mechanism 332, a cantilever 333, a housing 334, and a second motion mechanism 335. The fixed frame 331 is used to fix the multi-axis motion module 330 at a predetermined position. The first motion mechanism 332 is installed inside the fixed frame 331. One end of the cantilever 333 is located at the top of the fixed frame 331 and is driven by the first motion mechanism 332 to rotate around a first axis 3a in the horizontal plane. The housing 334 is arranged at the end of the cantilever 333 away from the fixed frame 331, and the housing 334 is located above the cantilever 333. The second motion mechanism 335 is installed in the housing 334 and connected to the end of the cantilever 333 away from the fixed frame 331, which is used to drive the housing 334 to rotate around a second axis 3b in the horizontal plane. The lifting mechanism 320 is also installed in the housing 334 and spaced a predetermined distance from the second motion mechanism 335. The variable distance module 340 is connected to the bottom of the lifting mechanism 320, and the adsorption module 310 is connected to the variable distance module 340. Among them, the first axis 3a and the second axis 3b are the axes located at both ends of the cantilever 333, and both are vertical axes. Among them, the above multi-axis motion module 330 is a prior art device, which is widely used in automated production lines. The first motion mechanism 332 and the second motion mechanism 335 in the multi-axis motion module 330 can be realized by a structure in which a motor drives a rotating shaft through a gear set (or a belt wheel combination) (the specific structure of the first motion mechanism 332 and the second motion mechanism 335 is not shown in the figure).

[0060] Before the adsorption module 310 adsorbs the PTC ceramic heating sheet 800, the variable distance module 340 pre-drives each adsorption module 310 to synchronously reduce the arrangement interval, so that each adsorption module 310 corresponds to each PTC ceramic heating sheet 800 linearly arranged in the first designated area 1a. After the adsorption module 310 adsorbs the PTC ceramic heating sheet 800 from the first designated area 1a, the variable distance module 340 drives each adsorption module 310 to synchronously increase the arrangement interval, so that each adsorbed PTC ceramic heating sheet 800 matches the interval between the grooves 910 on the copper disc 900 in the second designated area 2a.

[0061] The purpose of setting the variable distance module 340 is that when the PTC ceramic heating sheet 800 is linearly arranged in the first designated area 1a, that is, each PTC ceramic heating sheet 800 is arranged one by one (see Figure 2 When the PTC ceramic heating sheet 800 is transferred to the copper disc 900, the grooves 910 between the copper discs 900 have an interval (see Figure 4); so in the adsorption PTC ceramic heating sheet 800, need to let each adsorption module 310 close, ensure that each adsorption module 310 can accurately suck to PTC ceramic heating sheet 800, and after adsorption, need to let each adsorption module 310 separate, to match the pitch of groove hole 910 on copper disc 900, ensure that PTC ceramic heating sheet 800 can be accurately placed into groove hole 910. Therefore, the utility model specially configures the above-mentioned variable pitch module 340 for adjusting the pitch of adsorption module 310 to match different requirements of adsorption and placement.

[0062] The specific working process of the above-mentioned code disc mechanical hand 300 is as follows:

[0063] The multi-axis motion module 330 drives the adsorption module 310 to move above the first specified area 1a; before the adsorption module 310 adsorbs the PTC ceramic heating sheet 800, the variable pitch module 340 drives each adsorption module 310 to synchronously reduce the arrangement pitch in advance, so that each adsorption module 310 corresponds to each PTC ceramic heating sheet 800 linearly arranged in the first specified area 1a; then, the lifting mechanism 320 works, and the adsorption module 310 moves downward, and when the suction nozzle 311 approaches the PTC ceramic heating sheet 800, the suction nozzle 311 immediately inhales and adsorbs the PTC ceramic heating sheet 800; then, the lifting mechanism 320 works in reverse, and the adsorption module 310 moves upward, and at the same time, the variable pitch module 340 drives each adsorption module 310 to synchronously increase the arrangement pitch, so that the pitch of each adsorbed PTC ceramic heating sheet 800 is consistent with the pitch of the groove hole 910 on the upper surface of the copper disc 900; then, the first motion mechanism 332 works, and the second motion mechanism 335 works at the same time, so that the adsorption module 310 moves above the copper disc 900 in the second specified area 2a; then, the lifting mechanism 320 works, and the adsorption module 310 moves downward, and when each PTC ceramic heating sheet 800 approaches the corresponding groove hole 910 of the copper disc 900, the suction nozzle 311 stops inhaling, and each PTC ceramic heating sheet 800 is placed in the corresponding groove hole 910; in this way, a round of PTC ceramic heating sheet 800 code disc is completed; then, the first motion mechanism 332, the second motion mechanism 335 and the lifting mechanism 320 drive the adsorption module 310 to return above the first specified area 1a, and the second round of PTC ceramic heating sheet 800 code disc starts; then, the process is repeated until all PTC ceramic heating sheets 800 are completed or all groove holes 910 on the copper disc 900 are filled with PTC ceramic heating sheets 800.

[0064] The working principle of the automatic code disc device is as follows:

[0065] When working, the heating sheet conveying belt 100 successively transports a plurality of PTC ceramic heating sheets 800 to the first designated area 1a in the horizontal direction, and under the blocking of the first positioning mechanism 110, the plurality of PTC ceramic heating sheets 800 are linearly queued and stopped in the first designated area 1a; at the same time, the copper disc conveying belt 200 successively transports a plurality of copper discs 900 to the second designated area 2a in the horizontal direction, and when the foremost copper disc 900 moves to the second designated area 2a, the copper disc conveying belt 200 stops running, and then the second positioning device 210 works to clamp the copper disc 900 stably (the working process of the second positioning device 210 clamping the copper disc 900 has been described above);

[0066] Subsequently, the code disc manipulator 300 works to firstly grab the plurality of PTC ceramic heating sheets 800 from the first designated area 1a, and then shifts to the second designated area 2a to release the grabbed PTC ceramic heating sheets 800 into the slot holes 910 of the copper disc 900 (the working process of the code disc manipulator 300 shifting the PTC ceramic heating sheets 800 has been described above); in the shifting process, the heating sheet conveying belt 100 will transport the next batch of PTC ceramic heating sheets 800 (the number shown in the figure is four) to the first designated area 1a and stop here; after completing the action of grabbing-shifting-releasing once, the code disc manipulator 300 returns to the first designated area 1a again to continue the action of grabbing-shifting-releasing for the second time; subsequently, the action of grabbing-shifting-releasing is repeatedly repeated until all the slot holes 910 of the copper disc 900 are filled with the PTC ceramic heating sheets 800.

[0067] Subsequently, the copper disc conveying belt 200 starts running to convey the copper disc 900 to the subsequent printing process, and also conveys the next copper disc 900 to be coded to the second designated area 2a; subsequently, the previous action is continuously repeated to fill all the slot holes 910 of the next copper disc 900 with the PTC ceramic heating sheets 800.

[0068] Therefore, through the cooperative work of the heating sheet conveying belt 100, the copper disc conveying belt 200 and the code disc manipulator 300, the automatic coding of the PTC ceramic heating sheets is realized, the production efficiency and the coding quality are improved, the labor cost is reduced, and the rhythm and quality requirements of the automatic production are met.

[0069] The preferred embodiments of the utility model are described above only, and are not used for limiting the utility model, for the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
