Description

Technical Field

[0001] This invention relates to a processing device for a PTC electric heater, specifically a PTC electric heater hot pressing curing device. Background Technology

[0002] During the assembly of the PTC electric heater, the heat sink needs to be fixedly installed on the outer surface of the aluminum tube of each heating unit. During the operation, after evenly applying adhesive to the inner side of the two corrugated strips (heat sink), the heating unit is bonded between them. In subsequent processes, the heat sink and the aluminum tube of the heating unit also need to be cured at high temperature. The conventional curing method is to place them on the assembly equipment and then directly power the PTC electric heater to make it heat up, thereby completing the hot pressing curing operation on the assembly equipment.

[0003] In the above-mentioned conventional operation process, on the one hand, it is difficult to accurately fix the relative positions of each heat sink and each heating unit in the PTC electric heater that need to be hot-pressed and cured. On the other hand, it is also difficult to ensure that the relative positions of each part remain unchanged during the hot-pressing and curing process when the whole assembly is placed on the assembly equipment. Therefore, the hot-pressing and curing quality is poor. In particular, the existing assembly equipment is just a simple platform. Usually, each PTC electric heater is positioned manually using simple clamps and then wired separately. This not only easily leads to positioning reliability problems (positioning before and during the hot-pressing and curing process), but also makes it difficult to perform synchronous hot-pressing and curing of multiple PTC electric heaters. This makes the operation cumbersome, the production efficiency very low, and the space occupied by manual placement is large. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a PTC electric heater hot pressing curing device with ingenious structural design, convenient and quick operation and reliable positioning, thereby improving the quality of hot pressing curing.

[0005] To solve the above-mentioned technical problems, the PTC electric heater hot pressing curing equipment of the present invention includes an operating platform and at least one hot pressing station set on the operating platform. Each hot pressing station has a set of hot pressing positioning mechanism and also includes multiple hot pressing clamps for clamping the PTC electric heater to be hot pressed and cured. Each hot pressing clamp can be pressed and fixed by each set of the hot pressing positioning mechanism, and then hot pressing curing is performed by energizing the PTC electric heater to be hot pressed and cured.

[0006] The hot-press positioning mechanism includes a positioning seat, an upper pressing device located above the positioning seat, and a side pressing device located beside the upper pressing device. Each of the hot-press fixtures can be positioned by the positioning seat on each of the hot-press stations and pressed and fixed by the upper pressing device and the side pressing device on each of the hot-press stations.

[0007] The upper pressing device includes a support base and an upper hydraulic cylinder fixedly installed on the support base. The telescopic end of the upper hydraulic cylinder is equipped with an upper pressing block for pressing the top surface of the hot press fixture.

[0008] The positioning seat is provided with a pressure groove, and the hot pressing fixture is placed in the pressure groove and pressed by the upper pressure block.

[0009] The side-pressing device includes a mounting base and a side hydraulic cylinder fixedly mounted on the mounting base. The telescopic end of the side hydraulic cylinder cooperates with a side-pressing block to press the side of the hot press fixture.

[0010] The side pressure block is mounted on a horizontal telescopic arm. The lower part of the telescopic part of the horizontal telescopic arm is provided with a support guide wheel. The telescopic end of the side hydraulic cylinder can push the telescopic part of the horizontal telescopic arm to move horizontally back and forth.

[0011] The hot press fixture includes a base plate, a pair of side baffle structures on the base plate, and an end limiting component located at one end of one of the side baffle structures on the base plate. A positioning groove is formed between the pair of side baffle structures and the end limiting component for positioning multiple heating units and multiple heat sinks in the pre-assembled PTC electric heater.

[0012] The base plate also has a clamping component located on the opposite side of the end limiting component. The pre-assembled multiple heating units and multiple heat sinks are placed in the positioning groove and clamped and fixed by the clamping component.

[0013] The base plate is provided with ventilation holes and / or ventilation grooves.

[0014] The side baffle structure includes a side baffle for supporting the pre-assembled multiple heating units and multiple heat sinks, and at least one positioning pressure block located on the opposite side of the side baffle.

[0015] The advantages of this invention are:

[0016] (1) The PTC electric heater to be hot-pressed and cured can be clamped directly by the hot press clamp and then pressed and positioned by the hot press positioning mechanism. Then, the PTC electric heater to be hot-pressed and cured is heated by energizing it. Its structure is ingeniously designed. It can not only be reliably clamped and positioned by the special hot press clamp before hot-pressing and curing, but also achieve the operation stability and reliability of the entire hot-pressing and curing process through the hot press positioning mechanism, which greatly improves the quality of hot-pressing and curing.

[0017] (2) Multiple hot pressing stations are set on the operating platform, so that multiple PTC electric heaters can be hot-pressed and cured at the same time. During the hot pressing and curing process, it is only necessary to power on each PTC electric heater. The operation is very convenient and the method of processing multiple PTC electric heaters at the same time further improves the work efficiency.

[0018] (3) The hot pressing positioning mechanism consists of an upper pressing device and a side pressing device, which enables it to press and position from the top and the side. Its three-dimensional structural layout reduces the horizontal occupation of the operating platform space, allowing more products to be processed in a limited space, and further improving processing efficiency.

[0019] (4) By using the horizontal telescopic arm with supporting guide wheel and the side hydraulic cylinder to push and guide, the stability and reliability of clamping are further improved.

[0020] (5) The specific structural design of the hot press fixture can reliably position and clamp the heat sink and heating unit of the PTC electric heater before hot pressing and curing, and ensure that it can be directly placed in the pressure groove at the positioning seat after clamping. The placement is quick and convenient and effectively ensures the clamping reliability during the hot pressing and curing process. Attached Figure Description

[0025] The PTC electric heater assembly equipment of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] As shown in the figure, the PTC electric heater assembly equipment of the present invention includes an operating platform 1 and multiple hot pressing stations 2 set on the operating platform. Each hot pressing station 2 includes a positioning seat 3, an upper pressing device 4 located above the positioning seat, and a side pressing device 5 located beside the upper pressing device. Each hot pressing station 2 has a set of hot pressing positioning mechanism 3, and also includes multiple hot pressing jigs 5 for clamping the PTC electric heater 4 to be hot-pressed and cured. As can be seen from the figure, each hot pressing positioning mechanism 3 includes multiple positioning seats 6, an upper pressing device 7 located above each positioning seat, and multiple side pressing devices 8 located beside the upper pressing device. The PTC electric heater 4 is provided with electrodes extending out of the hot pressing jigs 5. Each hot pressing jig 5 can be positioned by the positioning seat 6 on each hot pressing station, and pressed and fixed by the upper pressing device 7 and the side pressing device 8 on each hot pressing station. Then, the electrodes of the PTC electric heater 4 to be hot-pressed and cured are hot-pressed and cured by energizing them. According to the test, taking the three hot pressing stations 2 in this embodiment as an example, the production cycle is 400 pieces / hour.

[0027] Furthermore, each of the aforementioned upper pressing devices 7 includes a support base 9 and an upper hydraulic cylinder 10 fixedly mounted on the support base (each upper pressing device 7 may share the same support base 9 or may have a separate support base). The upper hydraulic cylinder 10 necessarily has a fixed cylinder body and a telescopic end. The telescopic end of the upper hydraulic cylinder 10 is equipped with an upper pressing block 11 for pressing the top surface of the hot pressing fixture 5. A pressing groove is provided at the positioning seat 6. The hot pressing fixture 5 is placed in the pressing groove and pressed from the top by the upper pressing block 11. Each of the aforementioned side pressing devices 8 includes a mounting base 12 and a side hydraulic cylinder 13 fixedly mounted on the mounting base. The side hydraulic cylinder 13 also has a cylinder body and a telescopic end. The telescopic end of the side hydraulic cylinder 13 cooperates with a side pressing block 14 to press the side of the hot pressing fixture 5.

[0028] Furthermore, for the side pressure device 8, the following specific structural design can also be adopted: the side pressure block 14 is installed on a horizontal telescopic arm 15. The horizontal telescopic arm 15 includes a fixed cylinder fixedly installed on the support base 9 in the horizontal direction and a telescopic component that cooperates with the fixed cylinder (i.e., the telescopic part of the horizontal telescopic arm 15). The lower part of the telescopic component is provided with a support guide wheel 24. The telescopic end of the side hydraulic cylinder 13 can push the telescopic component to move horizontally in the fixed cylinder, thereby realizing horizontal reciprocating movement.

[0029] Furthermore, the hot press fixture 5 mentioned in this invention includes a base plate 16, a pair of side baffle structures 17 provided on the base plate, and an end limiting component 18 provided on the base plate at one end of the side baffle structures. The side baffle structure 17 includes a side baffle 22 for supporting the pre-assembled multiple heating units and multiple heat sinks, and at least one positioning block 23 located on the opposite side of the side baffle. The end limiting component 18 is provided with an electrode insertion hole, thereby allowing the electrode of the PTC electric heater 4 to be hot-pressed and cured to extend out of the hot press fixture 5 from the electrode insertion hole for energizing. A positioning groove is formed between the pair of side baffle structures 17 and the end limiting component 18 for positioning the multiple heating units 19 and multiple heat sinks 20 in the pre-assembled PTC electric heater 4. The base plate 16 also has a pressing component 21 located on the opposite side of the end limiting component 18. The pre-assembled multiple heating units 19 and multiple heat sinks 20 are placed in the positioning groove and pressed and fixed by the pressing component 21.

[0030] In addition, to achieve good ventilation and avoid uneven heating, ventilation holes and ventilation grooves can be arranged on the base plate 16, and ventilation holes or ventilation grooves can be designed separately.
