Description

Technical Field

[0001] This invention relates to a PTC heater assembly device with electrical testing function, belonging to the field of assembly technology. Background Technology

[0002] PTC heating elements, also known as PTC heaters, consist of PTC ceramic heating elements and aluminum tubes. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic temperature-controlled, energy-saving electric heater. Its outstanding feature is its safety performance; under any application, it will not produce the surface "red-hot" phenomenon seen in electric heating tube heaters, thus avoiding safety hazards such as burns and fires. PTC heating elements utilize U-shaped corrugated heat sinks, improving heat dissipation and combining the advantages of adhesive and mechanical bonding. It fully considers various thermal and electrical phenomena of the PTC heating element during operation, resulting in strong bonding, excellent thermal conductivity and heat dissipation, high efficiency, and reliable safety. This type of PTC heater has the advantages of low thermal resistance and high heat exchange efficiency, making it an automatic temperature-controlled, energy-saving electric heater. A major highlight is its safety performance: when the fan fails and stops, the PTC heater cannot dissipate heat sufficiently, and its power will automatically and rapidly decrease. At this time, the surface temperature of the heater will be maintained at around the Curie temperature (generally around 250℃), thus preventing the surface "red-hot" phenomenon seen in electric heating tube heaters.

[0003] In the industrial manufacturing of PTC heaters, the assembly process typically includes electrode pressing, lead wire welding, shell encapsulation, and final circuit performance testing. Among these, the capping process, as the final structural forming step to achieve electrical insulation and environmental protection, directly determines the long-term reliability of the product due to its process stability. However, in the existing technology system, circuit continuity testing is always performed as an independent post-process, completely decoupled from the capping process. After capping, the product needs to be transferred to a dedicated testing station to verify circuit continuity through insulation resistance measurement or contact probe continuity testing. If an open circuit, poor soldering, or insulation failure is found, the capped product must be destructively disassembled, internal components replaced, and reassembled. This process not only takes 15-30 minutes per piece to rework, but also significantly increases the risk of batch scrap due to deformation of the plastic shell and peeling of the sealing layer caused by mechanical stress. The industry average rework rate is generally higher than 8%. Therefore, we propose a PTC heater assembly equipment with electrical testing function. Summary of the Invention

[0004] The purpose of this invention is to provide a PTC heater assembly device with electrical testing function to solve the problems mentioned in the background art.

A clamping sleeve is fixedly installed at the bottom end of the movable frame, and an outer conductive block is fixedly installed inside the clamping sleeve. The bipolar pulse constant current source is connected to the outer conductive block through a wire.

[0008] Furthermore, the drive structure includes a clamping telescopic column, an active block, and a linkage block. The clamping telescopic column is installed above the inspection and assembly platform, the active block is fixedly installed on the movable frame, the output shaft of the clamping telescopic column is fixedly connected to the active block, and the top of the active block is fixedly supported by the linkage block.

[0009] Furthermore, the assembly component includes a limiting frame, with a limiting block fixedly supported on the inner wall of the limiting frame. Two limiting plates are fixedly connected to the inner bottom surface of the limiting frame. A second spring is fixedly connected to the top surface of the limiting frame. A limiting sleeve is fixedly installed on the top end of the second spring. A connecting block is fixedly connected to the inner bottom surface of the limiting sleeve.

An assembly frame is fixedly installed at the bottom end of the connecting block. A third spring is fixedly connected inside the assembly frame. The third spring supports an assembly gripper that is movably fitted inside the assembly frame.

[0010] Furthermore, the limiting plate is fixedly installed with a support sleeve, and a fourth spring is fixedly connected inside the support sleeve. The other end of the fourth spring is fixedly supported by a support bar that is movably fitted inside the support sleeve, and a housing is fixedly supported above the two support bars.

[0011] Furthermore, a feeding component is provided above the inspection assembly platform, located outside the assembly components. The feeding component includes a feeding telescopic column and a feeding pipe. The feeding telescopic column is fixedly supported outside the limiting frame, and the feeding pipe is located outside the limiting plate. The feeding telescopic column can push the housing to move above the support bar.

[0012] Furthermore, the material changing component includes a conveyor belt, which is fixedly connected to the outside of the inspection and assembly platform. Two telescopic columns are fixedly installed on the outside of the conveyor belt. A connecting frame is fixedly connected to the outside of the output shaft of the telescopic column, and a feeding gripper is supported on the inner side of the two connecting frames.

[0013] Furthermore, the arc surface of the outer conductive block fits into the arc surface of the inner conductive block, and the outer conductive block will squeeze the inner conductive block to clamp the PTC cells towards the center.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By inspecting the assembly platform, it can drive the PTC to rotate sequentially during use, complete the transfer of multiple workstations, and simultaneously achieve synchronous processing of multiple workstations. The PTC circuit is tested in the pre-assembly process, and waste is diverted to ensure that the assembled finished products are all good products. At the same time, the positioning plate above the support frame can perform limit positioning, and the conductive clamp and arc-shaped spring can achieve stable clamping.

[0016] By using a bipolar pulse constant current source, the clamping sleeve and clamping frame supported by the movable frame and positioning plate are used to limit the movement of the outer and inner conductive blocks. At the same time, the first spring helps to achieve a tight fit between the inner and outer conductive blocks, thus ensuring the stability of conductivity and avoiding the impact of unstable power supply on the stability of detection. The positioning plate can also help to position the clamping frame and the PTC.

[0017] By setting a limiting frame and installing a limiting block on the inner side of the limiting frame, the position of the clamping sleeve can be limited during the movement of the assembly frame, thereby controlling the clamping sleeve to clamp the shell during its movement. At the same time, after pressing to the appropriate position, the clamping sleeve will separate from the shell, making it easy to reset the empty clamp and continuously perform assembly processing.

[0018] By using the clamping telescopic column, the output shaft of the clamping telescopic column can control the movement of the active block. At the same time, the transmission of the linkage block can squeeze the driven block to move downward, completing the assembly of the parts. During the processing, the movement of the detection component can drive the pressing and assembly of the assembly parts, and the processing is carried out synchronously. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-11 The present invention provides a technical solution: A PTC heater assembly equipment with electrical testing function improves space utilization by setting up a circular workstation. At the same time, the testing workstation is located upstream of the assembly workstation, and the testing can be completed before assembly during the processing, thus avoiding the large losses caused by direct installation. Meanwhile, the assembly workstation can be driven to process simultaneously during the testing process, thereby achieving efficient synchronous testing and processing.

[0024] The assembly platform is supported by assembly components. The assembly component station is located downstream of the clamping contact station. The assembly component is driven by the electrical detection component to assemble the PTC and the housing.

[0025] See Figure 1-3An inspection and assembly platform is installed between several material changing components. The inspection and assembly platform includes a processing frame 1, and a processing platform 3 is movably mounted on the inner top surface of the processing frame 1. A servo motor 2 with an output shaft connected to the processing platform 3 is fixedly installed inside the processing frame 1. The output shaft of the servo motor 2 can drive the processing platform 3 to rotate, thereby controlling the processing platform 3 to drive the PTC above to rotate, realizing the transfer of different processing stations. A support frame 4 is fixedly supported above the processing frame 1. The support frame 4 can cooperate to support the drive structure and assembly components above, thereby cooperating with the drive components to simultaneously control the operation of the assembly components and the inspection components. A positioning piece 5 is fixedly connected above the processing platform 3. A conductive clip 6 is fixedly installed on the top of the positioning piece 5. An arc-shaped spring piece 7 is fixedly supported inside the conductive clip 6. The positioning piece 5 plays a role in positioning and can also restrict movement.

[0026] See Figure 4-8 An electrical testing component for testing PTCs is installed above the inspection and assembly platform. The inspection and assembly platform assists the electrical testing component in testing PTCs. The PTC is fixed above the inspection and assembly platform while two cells are connected, so that the two cells are in a conductive state, and the testing of two cells can be completed simultaneously. The electrical testing component includes a driving structure and a testing structure. The testing structure includes a bipolar pulse constant current source 12 and a movable frame 17.

[0027] A support spring 19 is connected to the outside of the movable frame 17. The other end of the support spring 19 is fixedly connected to a positioning plate 18 that fits against the bottom surface of the movable frame 17. During the movement, the movable frame 17 will first drive the positioning plate 18 to move. At the same time, the clamping frame 20 and clamping sleeve 21 on the inner side of the movable frame 17 and the positioning plate 18 will move synchronously. After the positioning plate 18 moves to the outside of the PTC, the outside of the positioning plate 18 is blocked by the PTC. Then the movable frame 17 will compress the support spring 19. The clamping frame 20 is fixedly connected to the outside of the positioning plate 18. One end of the first spring 24 is fixedly installed inside the clamping frame 20. The other end of the first spring 24 supports the conductive block 23 located inside the clamping frame 20. The clamping sleeve 21 is fixedly installed at the bottom of the movable frame 17.

[0028] After the positioning plate 18 comes to a stop, the clamping frame 20 will also come to a stop. Then, the clamping sleeve 21 will continue to move under the drive of the movable frame 17, thereby driving the inner outer conductive block 22 to move towards the center of the processing platform 3. The inclined surfaces of the outer conductive block 22 and the inner conductive block 23 are in contact, thereby squeezing the inner conductive block 23 and compressing the first spring 24. The inner conductive block 23 will continue to move towards the center of the clamping frame 20 until the two inner conductive blocks 23 squeeze and adhere to the outside of the two battery cells respectively. The outer conductive block 22 is fixedly installed inside the clamping sleeve 21. The bipolar pulse constant current source 12 is connected to the outer conductive block 22 through wires, thereby enabling the battery cells to complete the connection with the bipolar pulse constant current source 12, so that the bipolar pulse constant current source 12 can detect the circuit's continuity status. The arc surface of the outer conductive block 22 is in contact with the arc surface of the inner conductive block 23. The outer conductive block 22 will squeeze the inner conductive block 23 to clamp the PTC battery cells towards the center respectively.

[0029] The drive structure includes a clamping telescopic column 13, an active block 14, and a linkage block 15. The clamping telescopic column 13 is installed above the inspection and assembly platform. The active block 14 is fixedly installed on the movable frame 17. The output shaft of the clamping telescopic column 13 is fixedly connected to the active block 14. The top of the active block 14 is fixedly supported by the linkage block 15. The linkage block 15 is in contact with the driven block 16, and the contact surface between the linkage block 15 and the driven block 16 is an inclined surface. The horizontal movement of the linkage block 15 will push the driven block 16 to move downward.

[0030] See Figure 9-11 The assembly platform is supported by an assembly component. The assembly component station is located downstream of the clamping contact station. The assembly component includes a limiting frame 25. The inner wall of the limiting frame 25 is fixedly supported by a limiting block 29. The limiting block 29 guides the trajectory of the assembly gripper 33. During the downward movement of the assembly gripper 33, the assembly gripper 33 can stably clamp the housing 34. The limiting block 29 will squeeze the assembly gripper 33 to move towards the middle of the assembly frame 31 to clamp the housing 34. The width of the middle part of the limiting block 29 is greater than the width of the upper and lower ends, thus transporting it downward. Two limiting plates 30 are fixedly connected to the inner bottom surface of the limiting frame 25. The setting of the limiting plates 30 serves to limit the movement and can simultaneously support the support bar 37.

[0031] A second spring 27 is fixedly connected to the top surface of the limiting frame 25. A limiting sleeve 28 is fixedly installed at the top of the second spring 27. The limiting sleeve 28 is movably fitted onto the outside of the limiting frame 25. A connecting block 26 is fixedly connected to the bottom inner side of the limiting sleeve 28. A driven block 16 is fixedly supported on the outer side of the connecting block 26. The driven block 16 fits into the drive structure of the electrical detection component. An assembly frame 31 is fixedly installed at the bottom end of the connecting block 26. A third spring 32 is fixedly connected inside the assembly frame 31. The third spring 32 supports the assembly gripper 33 movably fitted inside the assembly frame 31.

[0032] During the downward movement, the assembly frame 31 will drive the assembly gripper 33 to move downward. As the assembly frame 31 moves downward under the push of the driven block 16 and the connecting block 26, the assembly frame 31 will gradually move to the outside of the housing 34. At the same time, the assembly gripper 33 will complete the clamping of the housing 34 under the pressure of the limiting block 29. After pushing the housing 34 to the outside of the PTC, the housing 34 will be separated. After the connecting block 26 and the driven block 16 are no longer subjected to downward pushing force, the second spring 27 will support the limiting sleeve 28 to return to its original position, thereby driving the connecting block 26 and the driven block 16 to return to their original position.

[0033] The limiting plate 30 is fixedly mounted with a support sleeve 36. A fourth spring 35 is fixedly connected inside the support sleeve 36. The other end of the fourth spring 35 is fixedly supported by a support bar 37 that is movably fitted inside the support sleeve 36. A housing 34 is fixedly supported above the two support bars 37. When the housing 34 moves downward... Above the inspection and assembly platform is a feeding component located outside the assembly components. The feeding component includes a feeding telescopic column 39 and a feeding pipe 38. The feeding telescopic column 39 is fixedly supported outside the limit frame 25, and the feeding pipe 38 is located outside the limit plate 30. The feeding telescopic column 39 can push the housing 34 to move above the support bar 37.

[0034] The material changing component includes a conveyor belt 8, which is fixedly connected to the outside of the inspection and assembly platform. Two telescopic columns 9 are fixedly installed on the outside of the conveyor belt 8. A connecting frame 10 is fixedly connected to the outside of the output shaft of the telescopic column 9. The inner side of the two connecting frames 10 supports the feeding gripper 11. The telescopic column 9 plays the role of conveying the PTC at the end of the conveyor belt 8 to the processing platform 3, completing the material transfer and removal. The feed port and waste port are opposite each other, and the inspection station and assembly station are opposite each other.

[0035] The workflow of this embodiment is as follows: By placing the PTC above the conveyor belt 8, the PTC is transported to a position close to the processing rack 1 by the conveyor belt 8. Then, the connecting frame 10 and the loading gripper 11 are controlled by the telescopic column 9 to clamp the PTC above the processing platform 3, so that the PTC fits the positioning piece 5. At the same time, the conductive clamp 6 and the arc-shaped spring piece 7 above the positioning piece 5 clamp the battery cell part respectively. Then, the servo motor 2 is started, and the servo motor 2 drives the processing platform 3 to rotate, so that the processing platform 3 rotates counterclockwise by one station from the top view, and the PTC is transferred to the inspection station.

[0036] The clamping telescopic column 13 is activated, and the output shaft of the clamping telescopic column 13 drives the active block 14 to move towards the processing platform 3. The active block 14 then drives the movable frame 17 and the support spring 19 to move forward synchronously with the positioning plate 18. After the positioning plate 18 is in contact with the outer side of the PTC, the positioning plate 18 stops moving and drives the movable frame 17 to continue moving. The movable frame 17 and the positioning plate 18 compress the support spring 19. Subsequently, the movable frame 17 pushes the clamping sleeve 21 and the outer conductive block 22 to move towards the processing platform 3 under the restriction of the clamping frame 20. After the outer conductive block 22 and the inner conductive block 23 are squeezed by the arc surface, the outer conductive block 22 will squeeze the inner conductive block 23 towards the middle of the clamping frame 20, so that the inner conductive block 23 is in contact with the PTC cell.

[0037] Start the bipolar pulse constant current source 12. Stage 1: Initial check of the room temperature path, 10ms, 100mA constant current pulse, voltage drop ≤50mV, resistance ≤0.5Ω, quickly screen out open circuits, cold solder joints, poor contact (95% of abnormalities are intercepted at this stage); Stage 2: Temperature control function verification, heat up to 80°C, 500mA constant current for 500ms, resistance jump ratio ≥15:1, response time τ≤1.2s, resistance jumps from ≤0.5Ω to ≥7.5Ω to verify the activity of PTC material and eliminate "false path" - normal resistance but no thermal protection capability.

[0038] After the inspection is completed, the connecting structure and PTC are separated by the clamping telescopic column 13 and the active block 14. Then, the processing platform 3 is started to drive the PTC to the next station. If the inspection shows that it is a waste material, it is sent out through this station. If the inspection shows that it is a normal part, this station is a misoperation. When it is transferred again, the PTC is transferred to the fourth station.

[0039] At this workstation, as the PTC clamps the telescopic column 13 and drives the active block 14 to retract, the driven block 16 is simultaneously pushed downward by the linkage block 15 above the active block 14. During the downward movement of the driven block 16, the connecting block 26 is simultaneously driven downward, causing the assembly frame 31 to move downward. During the movement of the assembly frame 31, the assembly gripper 33 is simultaneously driven to move. With the support of the limiting block 29 on the inner side of the limiting frame 25, the assembly gripper 33 is pushed towards the middle of the assembly frame 31, and the assembly gripper 33 is used to clamp the housing 34.

[0040] As the assembly frame 31 continues to move downwards, it will push the support bar 37 outwards, causing the support bar 37 to compress the fourth spring 35. This will prevent the support bar 37 from restricting the position of the housing 34. Subsequently, as the housing 34 is clamped downwards, it will be stably clamped to the outside of the PTC. At the same time, the limiting block 29 will no longer support the assembly claw 33 at the bottom, and the assembly claw 33 will separate from the housing 34. Then, during the reset of the active block 14, the driven block 16 will no longer be subjected to external force. The second spring 27 will support the limiting sleeve 28 to move upwards, which will then drive the assembly frame 31 to reset through the connecting block 26. Finally, the feeding telescopic column 39 will push the housing 34 inside the feeding pipe 38 back above the two support bars 37.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
