Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PTC heater production and processing equipment, and particularly relates to a full-inspection PTC row piece device. BACKGROUND

[0002] A PTC thermistor is a typical temperature-sensitive semiconductor resistor. When the temperature exceeds a certain temperature, the resistance value of the PTC thermistor increases step by step with the increase of the temperature. The PTC thermistor is commonly used to manufacture a PTC heater. The PTC heater is a heating device composed of a PTC ceramic heating element and an aluminum pipe. The PTC heater is gradually widely used in various fields due to the characteristics of small thermal resistance, high heat exchange efficiency, automatic constant temperature, power saving, and the like.

[0003] At present, in a PTC production and processing factory, in order to ensure the quality of the PTC heater, the PTC ceramic heating element is usually subjected to sampling inspection. Related detection equipment is used to test the performance parameters of the PTC ceramic heating element, including strength, thickness, resistance, and appearance, and the like. The PTC ceramic heating element with a qualified yield rate is sequentially installed in a jig tray.

[0004] The sampling inspection can only determine the yield rate of the PTC ceramic heating element, and cannot detect the PTC ceramic heating element one by one. Only the PTC ceramic heating element that does not meet the sampling inspection requirements can be removed, and all unqualified PTC ceramic heating elements cannot be removed. The original PTC ceramic heating element has a low yield rate, which can cause the quality of the PTC heater manufactured by the PTC ceramic heating element to be reduced. Moreover, the PTC ceramic heating element is mostly manually tested by a worker on a corresponding detection table. The PTC ceramic heating element is transferred to the next station for detection after the detection at a certain station is completed. After all the performance parameters are tested, the qualified PTC ceramic heating element is installed in the jig tray. This method reduces the detection efficiency of the PTC ceramic heating element, reduces the installation efficiency of the PTC ceramic heating element on the jig tray, and reduces the yield rate of the PTC ceramic heating element. Therefore, a new scheme needs to be proposed to solve this problem. SUMMARY

The number of storage components 11 is set to two, so that the PTC ceramic heating element 100 in one storage component 11 can be replaced with the next storage component 11 in a timely manner after it is used up, thus ensuring the continuous operation of the PTC chip stacking equipment.

[0052] Reference Figure 1 and Figure 2 The lifting assembly 12 includes a lifting bracket 121 bolted to the frame 10, a lifting drive 122 bolted to the lifting bracket 121, a lifting screw 123 rotatably mounted on the lifting bracket 121 via bearings, at least one PTC ceramic heating element push rod 124 threaded onto the lifting screw 123, and a lifting guide rod 125 fixedly mounted on the lifting bracket 121. The lifting drive 122 is a servo stepper motor, which is connected to the lifting screw 123 via a coupling. The number of PTC ceramic heating element push rods 124 is set to 20, and the 20 PTC ceramic heating element push rods 124 are integrated into one unit. The integrated end is threaded onto the lifting screw 123. The number of lifting guide rods 125 is set to two, and the two lifting guide rods 125 are arranged parallel to the lifting screw 123. The lifting guide rods 125 and PTC ceramic heating element push rods 124 are slidably inserted and engaged.

[0053] When the lifting assembly 12 is working, the lifting drive component 122 drives the lifting screw 123 to rotate. Under the limiting and guiding action of the lifting guide rod 125, the lifting screw 123 drives the PTC ceramic heating element push rod 124 to move. The PTC ceramic heating element push rod 124 slides in the PTC ceramic heating element mounting slot 113, lifting the PTC ceramic heating element 100 to ensure that the top of the PTC ceramic heating element mounting slot 113 always has a PTC ceramic heating element 100. When a product is removed from the PTC ceramic heating element mounting slot 113, the lifting assembly 12 lifts upward by one unit dimension of the thickness of the PTC ceramic heating element 100, keeping the end face of the PTC ceramic heating element 100 flush with the end face of the PTC ceramic heating element mounting slot 113.

[0054] Reference Figure 3 and Figure 4 The testing module 2 includes a strength testing station 21, a thickness testing station 22, a resistance testing station 23, and an appearance testing station 24, which are arranged at equal intervals.

[0055] The strength testing station 21 includes a strength testing base 211 fixed to the frame 10 by bolts, a strength cleaning air knife 212 bolted to the end of the strength testing base 211, a storage box 213 snapped onto the strength testing base 211, and a strength testing elastic displacement suction cup 214 inserted and installed on the material picking module 4.

[0056] The strength testing base 211 has an impurity port 215 along its length. In this embodiment, the number of impurity ports 215 is set to 20. Any impurity port 215 is connected to the chamber of the receiving cavity. The PTC ceramic heating element 100 is placed at the impurity port 215 through the material taking module 4. In the initial state, the overall size of the PTC ceramic heating element 100 is larger than the impurity port 215, so that the PTC ceramic heating element 100 will not fall off at the impurity port 215.

[0057] Two strength cleaning air knives 212 are provided, located at opposite ends of the strength testing base 211. Each strength cleaning air knife 212 includes an air knife seat 2121 bolted to the end of the strength testing base 211 and a rotating air knife 2122. The air knife seat 2121 has an air inlet 2123 and an air outlet 2124. The axes of the air inlet 2123 and the air outlet 2124 are perpendicular to each other. The end face of the air outlet 2124 faces the strength testing base 211 and has an impurity port 215. The rotating air knife 2122 is rotatably mounted in the air inlet 2123, and its end is rotatably mounted on the air knife seat 2121 via a bearing.

[0058] When the intensity cleaning air knife 212 is working, air enters through the air inlet 2123. Rotating the air knife 2122 pressurizes the air in the air inlet 2123, causing the air to be discharged from the air outlet 2124. The intensity cleaning air knife 212 cleans and blows air onto the impurities placed on the intensity testing base 211, causing the impurities to fall from the impurity outlet 215 into the storage box 213.

[0059] The strength detection elastic displacement suction cup 214 includes a vacuum tube transition shaft, a linear bearing 2144 that slides and is sleeved on the vacuum tube fixed shaft, a strength suction cup mounting part 2142, a pressure spring 2143, a depth adjustment ring 2146 and a pressure adjustment nut 2145 that are threadedly installed at both ends of the vacuum tube transition shaft, and a strength suction nozzle 2147 that is inserted and installed at the end of the pressure adjustment nut 2145 on the vacuum tube transition shaft. One end of the pressure spring 2143 abuts against the strength suction cup mounting part 2142, and the other end abuts against the pressure adjustment nut 2145. The number of strength detection elastic displacement suction cups 214 is set to 20, and the 20 strength detection elastic displacement suction cups 214 are arranged in a row.

[0060] The vacuum tube transition shaft is used to transmit negative pressure suction, which facilitates the adsorption and transfer of the PTC ceramic heating element 100 by the strength suction nozzle 2147. The strength suction cup mounting part 2142 realizes the fixed installation of the strength detection elastic displacement suction cup 214 on the material picking seat 42. By adjusting the position of the depth adjustment ring 2146 and / or the pressure adjustment nut 2145 on the vacuum tube transition shaft 2141, the initial elastic force of the pressure spring 2143 can be adjusted, thereby adjusting the force exerted by the strength detection elastic displacement suction cup 214 on the PTC ceramic heating element 100.

[0061] When the strength testing station 21 is working, the material picking module 4 drives the strength testing elastic displacement suction cup 214 to press down on the PTC ceramic heating element 100 placed on the strength testing base 211. The PTC ceramic heating element 100 that is not broken is qualified in strength, and the broken PTC ceramic heating element 100 falls from the impurity port 215 into the storage box 213.

[0062] The thickness detection station 22 includes a thickness detection base 221 bolted to the frame 10, thickness cleaning air knives 222 bolted to both ends of the thickness detection base 221, and thickness detection sensors 223 threaded and snapped onto the material handling module 4. The thickness detection base 221 is the same as the strength detection base 211, the only difference being that the thickness detection base 221 does not have an impurity port 215. The number and structure of the thickness cleaning air knives 222 are exactly the same as those of the strength cleaning air knives 212, and will not be described in detail here. The thickness detection sensors 223 are contact displacement sensors, and there are 20 thickness detection sensors 223 arranged in a row. Each thickness detection sensor 223 includes two sensing heads, which work together on the same PTC ceramic heating element 100, improving the detection efficiency and accuracy of the thickness detection sensor 223 on the PTC ceramic heating element 100.

[0063] When the thickness detection station 22 is working, the material handling module 4 drives the thickness detection sensor 223 to perform contact detection on the PTC ceramic heating element 100 placed on the thickness detection base 221. The thickness data of the PTC ceramic heating element 100 is obtained based on the displacement of the thickness detection sensor 223, and it is determined whether the PTC ceramic heating element 100 meets the relevant parameter standards.

[0064] The resistance testing station 23 includes a resistance testing base 231 bolted to the frame 10, resistance cleaning air knives 232 bolted to both ends of the resistance testing base 231, and resistance testing probes 233 threaded and snapped onto the material handling module 4. The resistance testing base 231 is identical to the thickness testing base 221. The number and structure of the resistance cleaning air knives 232 are exactly the same as those of the strength cleaning air knife 212, and will not be described further here. The number of resistance testing probes 233 is set to 20, arranged in a row.

[0065] When the resistance testing station 23 is working, the material picking module 4 drives the resistance testing probe 233 to perform contact testing on the PTC ceramic heating element 100 placed on the resistance testing base 231, and determines whether the PTC ceramic heating element 100 meets the relevant parameter standards.

[0066] Reference Figure 3 and Figure 5The appearance inspection station 24 includes a transparent appearance inspection base bolted to the frame 10, appearance cleaning air knives 242 bolted to both ends of the transparent appearance inspection base, and a vision assembly 243. The transparent appearance inspection base is the same as the thickness inspection base 221, the only difference being that the transparent appearance inspection base is a glass base, thus making it transparent. The number and structure of the appearance cleaning air knives 242 are exactly the same as those of the strength cleaning air knives 212, and will not be described further here.

[0067] The vision assembly 243 includes a vision bracket 2431 bolted to the frame 10, a vision servo motor 2435 bolted to the vision bracket 2431, and at least two vision wheels 2432 with bearings mounted on the vision bracket 2431. Two vision wheels 2432 are positioned near their respective ends on the vision bracket 2431. The servo motor drives one of its vision wheels 2432 to rotate via a coupling. A vision synchronization belt 2433 is sleeved between the two vision wheels 2432, and at least one CCD camera 2434 is bolted to the vision synchronization belt 2433. The vision assembly 243 consists of two components, positioned on the upper and lower sides of the transparent base for appearance inspection.

[0068] When the appearance inspection station 24 is working, the PTC ceramic heating element 100 is placed on the transparent appearance inspection base. The vision servo motor 2435 drives the vision wheel 2432 to rotate, which in turn drives the vision synchronization belt 2433 to rotate. The vision synchronization belt 2433 drives the CCD camera 2434 to move along the length of the transparent appearance inspection base 241. The CCD camera 2434 sequentially performs appearance inspection on the PTC ceramic heating element 100 to determine whether its appearance meets the standards. The two vision components 243 are respectively placed on the upper and lower sides of the transparent appearance inspection base 241, and simultaneously inspect the upper and lower sides of the PTC ceramic heating element 100 placed on the transparent appearance inspection base 241. This eliminates the need to flip the PTC ceramic heating element 100, improving the appearance inspection efficiency of the PTC ceramic heating element 100.

[0069] Reference Figure 1 and Figure 3The defective product collection module 3 includes a defective product conveying drive 31 bolted to the frame 10, a defective product conveying wheel 32 keyed to the output shaft of the defective product conveying drive 31, a defective product conveying support 33 bolted to the frame 10, and a defective product collection conveyor belt 34 sleeved and connected between the defective product conveying support 33 and the defective product conveying wheel 32. Multiple defective product collection modules 3 are provided. In this embodiment, three defective product collection modules 3 are provided, and each module is positioned on one side of the resistance detection station 23, the thickness detection station 22, and the appearance inspection station 24.

[0070] Reference Figure 3 and Figure 6 The material handling module 4 includes a material handling space displacement robot arm 41 that is fixedly mounted on the frame 10 by bolts and a material handling seat 42 that is bolted to the material handling space displacement robot arm 41.

[0071] The material handling space displacement robot arm 41 achieves displacement in the Y-axis direction by driving the lead screw to rotate via a servo motor, thereby causing the mounting seat on the lead screw to slide. The material handling space displacement robot arm 41 achieves displacement in the Z-axis direction by extending and retracting a cylinder, which is mounted on the mounting seat of the lead screw.

[0072] The material handling seat 42 is installed at the end of the cylinder of the material handling space displacement robot arm 41. At least one PTC ceramic heating element hopper material handling suction cup 43, at least one thickness detection displacement suction cup 44, and at least one resistance detection displacement suction cup 45 are installed on the material handling seat 42 through nuts. There are 20 of each of the three: PTC ceramic heating element hopper material handling suction cup 43, thickness detection displacement suction cup 44, and resistance detection displacement suction cup 45, corresponding to 20 PTC ceramic heating elements 100 in the PTC ceramic heating element mounting slots 113.

[0073] The strength detection elastic displacement suction cup 214, the thickness detection sensor 223, and the resistance detection probe 233 are all mounted on the material handling seat 42. The PTC ceramic heating element hopper material handling suction cup 43, the strength detection elastic displacement suction cup 214, the thickness detection sensor 223, the thickness detection displacement suction cup 44, the resistance detection probe 233, and the resistance detection displacement suction cup 45 are arranged sequentially on the material handling seat 42 along the feeding direction of the PTC ceramic heating element 100, and the PTC ceramic heating element hopper material handling suction cup 43, the strength detection elastic displacement suction cup 214, the thickness detection displacement suction cup 44, and the resistance detection displacement suction cup 45 are arranged at equal intervals.

[0074] One way the material handling module 4 works is that the material handling space displacement robot arm 41 drives the material handling plate to move in space. The material handling space displacement robot arm 41 drives the strength detection elastic displacement suction cup 214, thickness detection sensor 223, resistance detection probe 233 and strength detection elastic block installed on the material handling plate to press against the PTC ceramic heating element 100, so as to realize contact detection of the PTC ceramic heating element 100.

[0075] The material handling space displacement robot arm 41 drives the strength detection elastic displacement suction cup 214, thickness detection sensor 223 and resistance detection probe 233 installed on the material handling seat 42 to simultaneously press against the corresponding PTC ceramic heating element 100, thereby realizing contact detection of PTC ceramic heating element 100.

[0076] Another working mode of the material handling module 4 is as follows: the material handling space displacement robotic arm 41 drives the material handling suction cup 43 of the PTC ceramic heating element hopper to pick up the PTC ceramic heating element 100 in the hopper module 1 and transfer it to the strength testing station 21; simultaneously, the strength testing elastic displacement suction cup 214 transfers the qualified PTC ceramic heating element 100 on the strength testing station 21 to the thickness testing station 22; simultaneously, the thickness testing displacement suction cup 44 transfers the qualified PTC ceramic heating element 100 on the thickness testing station 22 to the resistance testing station 23; simultaneously, the resistance testing displacement suction cup 45 transfers the qualified PTC ceramic heating element 100 on the resistance testing station 23 to the appearance inspection station 24; the material handling module 4 performs synchronous movement of the PTC ceramic heating element 100 between the material handling module 4, the strength testing station 21, the thickness testing station 22, the resistance testing station 23, and the appearance inspection station 24, thereby improving the transfer and testing efficiency of the PTC ceramic heating element 100.

[0077] Another operating mode of the material handling module 4 is as follows: the material handling module 4, in conjunction with the thickness detection displacement suction cup 44 and the resistance detection displacement suction cup 45, transfers the unqualified PTC ceramic heating element 100 to its corresponding defective product collection conveyor belt 34. When the defective product collection module 3 is working, the defective product conveying drive unit 31 drives the defective product conveying wheel 32 to rotate, and the defective product conveying wheel 32 drives the defective product collection conveyor belt 34 to move. The defective product collection conveyor belt 34 conveys the unqualified PTC ceramic heating element 100 out of the machine for manual secondary confirmation.

[0078] Reference Figure 7 and Figure 8The buffer module 5 includes a buffer bracket 51 bolted to the frame 10, and at least two buffer rollers 52 rotatably mounted on the buffer bracket 51 via bearings. Two buffer rollers 52 are provided, and a buffer conveyor belt 53 is sleeved and connected between the two buffer rollers 52. A partition bracket mounting plate 54 is bolted to the buffer bracket 51, and 21 partitions 55 are integrally formed on the partition bracket mounting plate 54. PTC ceramic heating elements 100 are placed within 20 installation spaces formed by the 21 partitions 55, and the PTC ceramic heating elements 100 are supported on the buffer conveyor belt 53. 20 material shortage sensors 56 are installed on the partition bracket mounting plate 54, corresponding to the 20 PTC ceramic heating elements 100, and the material shortage sensors 56 detect whether there is a material shortage on the buffer conveyor belt.

[0079] When the buffer module 5 is working, the buffer wheel 52 drives the buffer conveyor belt 53 to rotate, and the buffer conveyor belt 53 drives the PTC ceramic heating element 100 to move. The PTC ceramic heating element 100 slides along the gap between two adjacent partitions 55, and the partitions 55 shape and position the PTC ceramic heating element 100.

[0080] The buffer loading and unloading displacement module 6 includes a buffer displacement module spatial displacement robot arm 61, a buffer loading and unloading mounting base 62 fixedly installed at the end of the buffer displacement module spatial displacement robot arm 61, and a reversing adsorption component 63 fixedly installed on the buffer loading and unloading mounting base 62.

[0081] The buffer displacement module spatial displacement robot arm 61 is the same as the material handling spatial displacement robot arm 41. It achieves the displacement of the buffer displacement module spatial displacement robot arm 61 in the Y-axis direction by driving the lead screw to rotate through a servo motor, thereby causing the mounting seat on the lead screw to slide. The buffer displacement module spatial displacement robot arm 61 achieves the displacement of the buffer displacement module spatial displacement robot arm 61 in the Z-axis direction by extending and retracting a cylinder, with the cylinder mounted on the lead screw mounting seat.

[0082] The reversing adsorption assembly 63 includes a telescopic cylinder 631 bolted to the buffer unloading / loading mounting base 62 and a rotating rack 632 bolted to the output shaft of the telescopic cylinder 631. The length direction of the rotating rack 632 is parallel to the telescopic direction of the telescopic cylinder 631. A buffer suction cup 633 is rotatably mounted on the buffer unloading mounting base. A rotating gear 634 is sleeved on the outer wall of the buffer suction cup 633, and the rotating gear 634 meshes with the rotating rack 632.

[0083] One operating mode of the buffer loading / unloading displacement module 6 is as follows: the telescopic cylinder 631 drives the rotating rack 632 to move along its own axis. The rotating rack 632 meshes with the rotating gear 634, driving the rotating gear 634 and the buffer suction cup 633 to rotate. The buffer suction cup 633 adsorbs the PTC ceramic heating element 100, and in conjunction with the reversing adsorption component 63, the PTC ceramic heating element 100 is reversed in the length and width directions. The storage module spatial displacement robotic arm drives the buffer loading / unloading mounting base 62 to undergo spatial displacement, and in conjunction with the buffer suction cup 633, transfers the PTC ceramic heating element 100 on the appearance inspection station 24 to the buffer module 5.

[0084] An angle-adjustable damper 635 is bolted to the loading / unloading displacement module 6. The angle-adjustable damper 635 is a shock-absorbing cylinder, and its end is pressed against the rotating rack 632. The angle-adjustable damper 635 dampens the movement of the rotating rack 632, thereby improving the stability of the rotating rack 632 during its movement.

[0085] Another way of working the buffer loading and unloading displacement module 6 is that the spatial displacement robot arm 61 of the buffer displacement module drives the buffer loading and unloading mounting base 62 to move spatially, and cooperates with the buffer suction cup 633 to transfer the unqualified PTC ceramic heating element 100 on the appearance inspection station 24 to the corresponding defective product collection conveyor belt 34 on one side of the appearance inspection station 24.

[0086] Reference Figure 7 and Figure 9 The shaping module 7 includes a shaping bracket 71 bolted to the frame 10, shaping rollers 72 rotatably mounted at both ends of the shaping bracket 71 by bearings, and a low-friction conveyor belt 73 sleeved between the two shaping rollers 72. End positioning plates 74 are bolted to both ends of the shaping bracket 71, and shaping cylinders 75 are bolted to both sides of the shaping bracket 71. Side positioning plates 76 are bolted to the output shaft of the shaping cylinders 75.

[0087] When the shaping module 7 is working, the low-friction conveyor belt 73 drives the PTC ceramic heating element 100 to move, and the end positioning plate 74 limits the PTC ceramic heating element 100, so that sliding friction is formed between the PTC ceramic heating element 100 and the low-friction conveyor belt 73. Multiple PTC ceramic heating elements 100 are arranged and pressed together along the conveying direction of the low-friction conveyor belt 73, realizing the arrangement and shaping of the PTC ceramic heating element 100 in the end direction. The shaping cylinder 75 drives the side positioning plate 76 to move towards the PTC ceramic heating element 100, and the two side positioning plates 76 move closer to each other, realizing the arrangement and shaping of the PTC ceramic heating element 100 in the two sides direction.

[0088] The overall structure of the shaping and assembly displacement module 9 is the same as that of the buffer loading and unloading displacement module 6. The only difference between the two is that the shaping and assembly displacement module 9 does not have a reversing adsorption component 63. The suction cup structure of the shaping and assembly displacement module 9 is directly installed on the shaping and assembly mounting base of the shaping and assembly displacement module 9.

[0089] One way the shaping and assembly displacement module 9 works is to move the PTC ceramic heating element 100, which has been shaped by the buffer module 5, to the shaping module 7.

[0090] Reference Figure 7 and Figure 9 The assembly module 8 includes an assembly conveyor belt device 81 mounted on the frame 10, a jig tray 82 placed on the assembly conveyor belt device 81, and a positioning component 83.

[0091] When the assembly module 8 is working, the assembly conveyor belt device 81 carries the fixture tray 82 and transfers the fixture tray 82 between the positioning components 83. Then, the shaping assembly displacement module 9 moves the PTC ceramic heating element 100, which has been shaped and positioned by the shaping module 7, onto the fixture tray 82 to realize the mounting of the PTC ceramic heating element 100. After the mounting is completed, the assembly conveyor belt device 81 drives the mounted fixture tray 82 to leave the mounting position.

[0092] Reference Figure 9 and Figure 10 The positioning assembly 83 includes positioning cylinders 831 bolted to the frame 10. The number of positioning cylinders 831 is set to four. A positioning block 832 is screwed onto the output shaft end of each positioning cylinder 831. The positioning block 832 has a V-shaped structure. A PTC ceramic heating element positioning groove 833 is provided on the fixture tray 82. The shape of the PTC ceramic heating element positioning groove 833 is adapted to the shape of the positioning block 832 and is also V-shaped. The positioning cylinders 831 are symmetrically arranged in pairs on both sides of the fixture tray 82.

[0093] When the positioning component 83 is working, the positioning cylinder 831 drives the positioning block 832 to move towards the jig tray 82 until the positioning block 832 is inserted into the positioning groove 833 of the PTC ceramic heating element, thereby realizing the positioning of the jig tray 82 by the positioning component 83.

[0094] One way the shaping and assembly displacement module 9 works is to transfer the PTC ceramic heating element 100, which has been shaped and positioned by the shaping module 7, to the jig tray 82 of the assembly module 8, thereby realizing the tray loading of the PTC ceramic heating element 100.

[0095] The implementation principle of the full-inspection PTC chip stacking equipment in this application embodiment is as follows: When the full-inspection PTC chip stacking equipment is working, the PTC ceramic heating element 100 is stored in the material hopper module 1. The material picking module 4 transfers the PTC ceramic heating element 100 in the material hopper module 1 to the detection module 2. The detection module 2 detects the strength, thickness, resistance, and appearance parameters of the PTC ceramic heating element 100. The material picking module 4 and the loading / unloading displacement module 6 transfer the PTC ceramic heating element 100 that fails the test to the defective product collection module 3. The defective product collection module 3 then processes the defective PTC ceramic heating element 100. The process involves collecting and loading / unloading PTC ceramic heating elements 100. The loading / unloading displacement module 6 transfers the qualified PTC ceramic heating elements 100 to the buffer module 5, where they are buffered. The shaping and assembly displacement module 9 then transfers the buffered PTC ceramic heating elements 100 from the buffer module 5 to the shaping module 7 for arrangement and shaping. The shaping and assembly displacement module 9 then transfers the PTC ceramic heating elements 100 from the shaping module 7 to the assembly module 8, where the assembly module 8, in conjunction with the shaping and assembly displacement module 9, loads the PTC ceramic heating elements 100 onto trays. This PTC arrangement equipment automates the entire process of PTC ceramic heating element 100 inspection and arrangement, eliminating the need for manual inspection, transfer, and arrangement, thus improving the low efficiency of PTC ceramic heating element inspection and installation.

[0096] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
