Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic product manufacturing and assembly equipment, and in particular to a pressure-holding fixture for an NFC module of an electronic product. Background Technology
[0002] In the manufacturing process of electronic products, many products equipped with NFC modules require a pressure-pressing operation on the NFC module during assembly before proceeding to the next assembly step. Currently, the pressure-pressing of NFC modules is generally done manually, one-by-one, or by manually operating a single pressing mechanism to avoid damaging the relatively fragile NFC module. This method results in low pressing efficiency, and the stability and precision of the pressing quality need improvement. Utility Model Content
[0003] This utility model provides a pressure-holding fixture for NFC modules of electronic products, which solves the technical problem that the existing NFC module pressure holding and pressing generally requires manual operation of pressing one by one or manual operation of a single pressing mechanism, and the pressing efficiency, quality stability and accuracy need to be improved.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a pressure-holding fixture for an NFC module of an electronic product, including a device frame with an operation window. The device frame is equipped with a horizontal drive mechanism with its two ends respectively positioned inside and outside the operation window. A contoured carrier plate for placing the product is driven to move horizontally on the horizontal drive mechanism. A fixed plate is positioned above the horizontal drive mechanism inside the operation window. A first vertical limiting component is provided on the fixed plate. A moving plate is limited by the first vertical limiting component to move vertically relative to the contoured carrier plate. A second vertical limiting component is provided on the moving plate. A contoured pressure head assembly is limited by the second vertical limiting component to move vertically relative to the contoured carrier plate to hold pressure on the product. A buffer elastic component is provided between the moving plate and the contoured pressure head assembly. A pressing drive mechanism for driving the moving plate to move vertically is provided on the fixed plate. A pressure sensing mechanism is provided between the pressing drive mechanism and the moving plate. Automatic transfer and alignment, convenient operation, and high-precision elastic pressing effectively improve the quality stability and efficiency of product pressing.
[0005] Furthermore, a coupling structure is provided between the pressing drive mechanism and the pressure sensing mechanism. This coupling structure includes a first coupling and a second coupling. The upper end of the first coupling is connected and fixed to the lower end of the pressing drive mechanism and is driven to move vertically by the pressing drive mechanism. The second coupling is fixed to the upper end of the pressure sensing mechanism by bolts. The first coupling includes an internally threaded connecting post connected to the pressing drive mechanism and a mating limiting platform protruding from the lower end of the internally threaded connecting post. The outer surface of the upper end of the internally threaded connecting post has multiple corresponding planes for the knob. One side of the second coupling has an installation groove extending towards its center for the internally threaded connecting post to pass through, and a limiting groove below the installation groove for limiting the mating limiting platform. Installation, disassembly, and maintenance are convenient.
[0006] Furthermore, the pressing drive mechanism is a stroke-controllable cylinder connected in sequence to a first pressure regulating valve and a second pressure regulating valve. The pressure regulating accuracy of the second pressure regulating valve is higher than that of the first pressure regulating valve. The second pressure regulating valve is connected to an external air source. This multi-stage high-precision pressure regulation ensures the accuracy and stability of the stroke control of the pressing drive mechanism, thereby guaranteeing the quality of product pressure holding.
[0007] Furthermore, the equipment platform is equipped with control buttons, a running indicator light, and a buzzer for operating the pressing drive mechanism. The control buttons include an emergency stop button and two start buttons for dual start. Operation is convenient and user-friendly.
[0008] Furthermore, a safety light curtain is installed on the operating window of the equipment platform. This provides good safety and prevents injury to operators.
[0009] Furthermore, the first vertical limiting assembly includes multiple sets of first flange bearings and first slide rods used in conjunction, and the second vertical limiting assembly includes multiple sets of second flange bearings and second slide rods used in conjunction. This simple structure achieves vertical limiting.
[0010] Furthermore, the contouring carrier plate has multiple alignment guide holes around the periphery where the product is placed. On the lower end face of the contouring pressure head assembly, corresponding to the alignment guide holes, are pressing guide alignment posts with an outer diameter identical to the inner diameter of the alignment guide holes. The lower end of each pressing guide alignment post has a smooth guide arc surface, and the upper end of each alignment guide hole has an outwardly expanding guide arc surface. During the pressing process, high-precision alignment and limiting, along with guidance, prevent jamming and ensure proper pressing.
[0011] Furthermore, the contouring carrier plate is equipped with placement limiting points for the product, and multiple product positioning pins are installed within these points. This high-precision product positioning ensures the quality of the pressure-holding production process.
[0012] Furthermore, a hydraulic damper is provided on one side of the horizontal drive mechanism within the equipment frame to limit the movement range of the contour plate. This limits the movement distance of the contour plate, preventing misalignment due to malfunctions from causing damage to the product during pressing.
[0013] Furthermore, the buffer elastic component includes multiple springs respectively sleeved on the second slide rod and located between the lower end face of the moving plate and the upper end face of the conformal pressure head assembly. The springs sleeved on the second slide rod provide greater stability during prolonged use, effectively improving the spring's service life and the stability of the elastic pressure applied to the product.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figure 1The NFC module pressure-holding fixture for an electronic product shown includes a device stand 100 with an operation window. The device stand 100 has a horizontal drive mechanism 200 with its two ends respectively positioned inside and outside the operation window. The horizontal drive mechanism 200 has a contoured carrier plate 300 for placing the product, which is driven to move horizontally by the mechanism. A fixing plate 110 is located above the horizontal drive mechanism 200 inside the operation window. The fixing plate 110 has a first vertical limiting component 400, which limits the relative contoured carrier plate 300. A movable plate 500 that moves vertically relative to the conforming carrier plate 300 is provided on the movable plate 500.

A pressing drive mechanism 800 that drives the movable plate 500 to move vertically is provided on the fixed plate 110.

In this specific embodiment, the pressure sensing mechanism 900 is a commercially available pressure sensor with a pressure gauge; the horizontal drive mechanism 200 includes a linear slide rail and a rodless cylinder assembly that works in conjunction with the linear slide rail; in specific implementation, the pressing drive mechanism 800 drives the moving plate 500 to move vertically relative to the contour carrier plate 300 on which the product is placed, under the limitation of the first vertical limiting component 400; the contour pressing head assembly 700, under the limitation of the second vertical limiting component 600, is driven by the moving plate 500 to move relative to the contour carrier plate 300 on which the product is placed, through the elastic force applied by the buffer elastic component, to maintain pressure on the product, and the pressure sensing mechanism 900 can ensure that the pressure meets the standard, guaranteeing the quality of product pressing. Automatic transfer and alignment, convenient operation, high-precision elastic pressing, effectively improve the quality stability and efficiency of product pressing.
[0020] Based on the above, such as Figure 1 and Figure 2As shown, a coupling structure is provided between the pressing drive mechanism 800 and the pressure sensing mechanism 900. The coupling structure includes a first connector and a second connector. The upper end of the first connector is connected and fixed to the lower end of the pressing drive mechanism 800 and is driven to move vertically by the pressing drive mechanism 800. The second connector is fixed to the upper end of the pressure sensing mechanism 900 by bolts. The first connector includes an internally threaded connecting post 811 connected to the pressing drive mechanism 800 and a mating limiting platform 812 protruding from the lower end of the internally threaded connecting post 811. The outer surface of the upper end of the internally threaded connecting post 811 is provided with a plurality of corresponding planes for the knob. One side of the second connector is provided with an installation groove 911 extending toward its center for the internally threaded connecting post 811 to pass through and a limiting groove 912 located below the installation groove 911 for limiting the mating limiting platform 812. During disassembly and maintenance, simply unscrew the internal threaded connecting post 811 from the lower end of the pressing drive mechanism 800, and then slide the internal threaded connecting post 811 and the mating limit table 812 out of the mounting groove 911 and the limit groove 912 respectively to complete the disassembly of the pressing drive mechanism 800 and the pressure sensing mechanism 900, thus making room for subsequent component disassembly. Installation, disassembly, and maintenance are convenient.
[0021] Based on the above, such as Figure 1 As shown, the pressing drive mechanism 800 is a stroke-controllable cylinder and is sequentially connected to a first pressure regulating valve 820 and a second pressure regulating valve 830. The pressure regulating accuracy of the second pressure regulating valve 830 is higher than that of the first pressure regulating valve 820. The second pressure regulating valve 830 is connected to an external air source. This multi-stage high-precision pressure regulation ensures the accuracy and stability of the stroke control of the pressing drive mechanism 800, thereby guaranteeing the quality of product pressure holding.
[0022] Based on the above, such as Figure 1 As shown, the equipment stand 100 is equipped with control buttons, a running indicator light, and a buzzer for operating the pressing drive mechanism 800. The control buttons include an emergency stop button and two start buttons for dual start. It is convenient to operate and has good operability.
[0023] Based on the above, such as Figure 1 As shown, a safety light curtain 120 is installed on the operating window of the equipment platform 100. This provides good safety performance and prevents injury to operators.

On the lower end face of the contouring pressure head assembly 700, corresponding to the alignment guide holes 310, there are pressing guide alignment posts 710 with the same outer diameter as the inner diameter of the alignment guide holes 310. The lower end of the pressing guide alignment post 710 has a smooth guide arc surface, and the upper end of the alignment guide hole 310 has an outwardly expanding guide arc surface. During the pressing process, high-precision alignment and limiting, as well as guidance, prevent jamming and failure to press into place.
[0026] Based on the above, such as Figure 1 and Figure 3 As shown, the contour carrier plate 300 is provided with placement limiting holes for placing products, and multiple product positioning pins are provided within the placement limiting holes. High-precision product positioning ensures the quality of pressure-holding production.
[0027] Based on the above, such as Figure 1 As shown, the horizontal drive mechanism 200 is equipped with a hydraulic damper on one side within the equipment frame 100 to limit the movement range of the contour plate 300. This limits the movement distance of the contour plate 300, preventing misalignment due to malfunctions from causing damage to the product during pressing.
[0028] Based on the above, such as Figure 1 and Figure 3 As shown, the buffer elastic component includes multiple springs 130 respectively sleeved on the second slide bar 620 and located between the lower end face of the moving plate 500 and the upper end face of the conformal pressure head assembly 700. The springs 130, sleeved on the second slide bar 620, provide greater stability during prolonged use, effectively improving the service life of the springs 130 and the stability of the elastic pressure on the product.
