An operation button 9 is provided on the front side of the frame 1, and the working status of the device can be controlled by the operation button 9.

[0023] A fixture base 11 is fixedly installed on the workbench 2. The fixture base 11 is used to clamp the product, and the top surface of the fixture base 11 is provided with a positioning groove that matches the product to achieve product positioning. A support plate 3 that can be raised and lowered is provided above the fixture base 11, and a pressing assembly 5 is installed at the bottom of the support plate 3. After the product is placed in the positioning groove of the fixture base 11, the workbench 2 moves down, and the heating element is pressed into the product by the pressing assembly 5.

[0024] Furthermore, a guide rod 6 is fixedly installed on the workbench 2, and a top plate 4 is fixedly installed on the top of the guide rod 6. The support plate 3 is located between the workbench 2 and the top plate 4, and is slidably sleeved on the guide rod 6 through a linear bearing 7. The guide rod 6 is perpendicular to the workbench 2, the support plate 3 and the top plate 4, that is, the workbench 2, the support plate 3 and the top plate 4 are parallel to each other.

[0025] A telescopic assembly 8 is installed on the top plate 4. The telescopic assembly 8 is parallel to the guide rod 6, and the output end of the telescopic assembly 8 passes through the top plate 4 and is connected to the support plate 3, thereby realizing the lifting function of the support plate 3.

[0026] Among them, the guide rod 6 plays a supporting and guiding role. The linear bearing 7 can reduce the friction and wear between the support plate 3 and the guide rod 6. The telescopic component 8 preferably adopts existing equipment that can output linear motion, such as pneumatic cylinder, electric cylinder or hydraulic cylinder.

[0027] To ensure that the components above the frame 1 can be press-fitted in a stable environment, a U-shaped guardrail 10 is installed on the top of the frame 1. The workbench 2, support plate 3 and top plate 4 are all located inside the guardrail 10, and the opening side of the guardrail 10 corresponds to the front side of the frame 1, so as to facilitate the loading and unloading of materials by the workers.

[0029] Wherein, a driving component is arranged inside the support 501 to drive the pressing head 502 to extend and retract along the axial direction, which can be a pneumatic cylinder, an oil cylinder or an electric cylinder, so that the pressing head 502 can extend and retract along the axial direction relative to the support plate 3; and before the pressing, the lower end of the pressing head 502 is located above the two ends of the spring piece 503.

[0030] During the pressing of the ceramic heating sheet, the pressing head 502 is first lowered to make the two ends of the spring piece 503 abut against the jig seat 11, and then the pressing assembly 5 is pressed downward as a whole by the support plate 3, so that the heating sheet is pressed into the product by the pressing head 502, and the impact force on the heating sheet is greatly reduced by the cooperation of the pressing head 502 and the spring piece 503, which effectively avoids the breakage of the heating sheet due to the large impact force and improves the reliability and safety of the product.

[0031] Specifically, the pressing head 502 penetrates the middle part of the spring piece 503, the top part of the spring piece 503 is parallel to the support plate 3, and the two ends of the spring piece 503 are first bent inward and then bent outward; this structure ensures that the spring piece 503 has a certain elasticity, so that when the pressing head 502 is subjected to downward impact, the deformation of the spring piece 503 can offset part of the impact force, ensuring that the ceramic heating sheet will not break due to the large impact force.

[0032] Wherein, the pressing head 502 is made of urea resin material, which effectively improves its flexibility and reliability, avoids the deformation of the spring piece 503 caused by hard contact during assembly, and also plays a buffering role for the ceramic sheet.

[0033] Further, the bottom of the support 501 is provided with a downward protruding lug, the lug is provided with a clearance hole corresponding to the contour of the spring piece 503, and the pressing head 502 penetrates out of the clearance hole; the clearance hole can ensure that the pressing head 502 can better realize the clearance pressing during the pressing process.

[0034] The pressing head 502 clearance fitting spring piece 503 positioning structure design adopts a telescopic pressing head 502, which not only realizes precise positioning of the spring piece 503, but also buffers the impact force of the pressing head 502.

[0035] In conclusion, the ceramic heating sheet pressure buckle device can reduce the impact of the equipment from 190kgf·cm to 100kgf·cm, and through the development of the jig, the problem of ceramic heating sheet rupture caused by external force deformation during assembly can be successfully solved, which greatly helps to improve product reliability and safety, and can be used as a reference for the process experience of materials with poor toughness and easy deformation.
