Description

Technical Field

[0001] This utility model relates to the field of pressure-holding equipment technology. More specifically, this utility model relates to a fingerprint module bending pressure-holding device. Background Technology

[0002] In the production of fingerprint modules, bending and bonding are required. Currently, the bending and bonding of fingerprint modules is generally achieved by placing the product into a bending fixture and having an operator manually press it to ensure the bending and bonding effect. However, because manual pressing is difficult to control precisely in terms of pressing time and pressure, it is hard to effectively activate the viscosity of the double-sided adhesive used for bending and bonding, and it is impossible to effectively guarantee the adhesion of the bending steel sheet in the product, resulting in unstable product quality. Therefore, it is necessary to develop a pneumatic pressure-holding device for bending fingerprint modules to precisely control the pressure and holding time, replacing manual pressing.

[0044] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0045] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] like Figures 1-4 As shown, an embodiment of this utility model provides a fingerprint module bending and pressure-holding device, comprising:

[0047] The control panel 1 is equipped with a vertical drive mechanism and a horizontal drive mechanism.

[0048] Mounting platform 2 has a fixing position at its upper end for fixing bending fixture 16, such as... Figure 1 As shown, mounting holes are provided on the bending fixture 16 and corresponding positioning holes are provided on the mounting table 2. A pin is provided in the mounting hole. The pin is inserted into the required positioning hole to fix the bending fixture 16 on the mounting table 2.

[0049] The mounting platform 2 is connected to the horizontal drive mechanism, and the horizontal drive mechanism drives the mounting platform 2 to move between the loading position and the pressure holding position;

[0050] A positioning detection mechanism is installed on the operating table 1 to detect whether the mounting table 2 is located at the feeding position or the pressure holding position;

[0051] Pressure plate 4 is positioned above the pressure holding position and is connected to the vertical drive mechanism for transmission.

[0052] In this embodiment, initially, the mounting platform 2 is located at the loading position, and the pressure plate 4 is at the highest point of its vertical movement trajectory. The holding pressure and time of the pressure plate 4 are preset. After the bending fixture 16 is fixed in the fixed position on the mounting platform 2, the fingerprint module product to be bent and bonded is placed in the bending fixture 16, and the bending and holding pressure device starts to work. Specifically, the horizontal drive mechanism drives the bending fixture 16 on the mounting platform 2 from the loading position to the holding pressure position. When the positioning detection mechanism detects that the mounting platform 2 is in the holding pressure position, the horizontal drive mechanism stops working, the bending fixture 16 reaches the holding pressure position, and at this time the horizontal drive mechanism stops working, and the bending fixture 16 stays in the holding pressure position. Then, the vertical drive mechanism moves the pressure plate 4 downwards until it is in contact with the upper end of the bending fixture 16. Using the vertical drive mechanism as a power source, the pressure plate 4 applies a holding pressure to the bending fixture 16 until the preset holding time is reached. Afterwards, the vertical drive mechanism moves the pressure plate 4 upwards to its initial position, separating the pressure plate 4 from the bending fixture 16. Then, the horizontal drive mechanism moves the bending fixture 16 on the mounting platform 2 from the holding position to the loading position, completing this holding pressure cycle and achieving the bending and bonding of the fingerprint module. After the holding pressure is completed, the horizontal drive mechanism moves the mounting platform 2 back to the loading position. When the positioning detection mechanism detects that the mounting platform 2 is in the loading position, the horizontal drive mechanism stops working, the bending fixture 16 returns to the loading position, the bent and bonded fingerprint module product is removed from the bending fixture 16, a new fingerprint module product to be bent and bonded is placed on top, and the bending and holding pressure device performs the next holding pressure cycle.

[0053] Preferably, in another embodiment of this utility model, the vertical drive mechanism includes: a gantry 5, which is mounted on the operating table 1; an air supply assembly, which is mounted on the gantry 5; and a first cylinder 6, which is mounted on the gantry 5 and connected to the air supply assembly, wherein the push rod of the first cylinder 6 is vertically downward and connected to the upper middle part of the pressure plate 4. The air supply assembly includes: an air source filter 7; a first vacuum generator 8, whose inlet is connected to the outlet of the air source filter 7; and a first solenoid valve 9, whose inlet is connected to the outlet of the first vacuum generator 8 and whose outlet is connected to the inlet of the first cylinder 6.

[0054] In this embodiment, a first power unit is formed by an air source filter 7, a first vacuum generator 8, and a first solenoid valve 9. The air source filter 7 is connected to an external air source, which can be compressed air, supplied to the air source filter 7 by a compressor, gas cylinder, or the like. By controlling the states of the first vacuum generator 8 and the first solenoid valve 9, the first power unit can supply or evacuate air to the first cylinder 6, thereby extending or retracting the push rod of the first cylinder 6.

[0055] Preferably, in another embodiment of the present invention, the vertical drive motor further includes:

[0056] At least one guide rod 10 is vertically arranged between the operating table 1 and the gantry 5, and the pressure plate 4 passes through the guide rod 10 and is slidably connected to it.

[0057] In this embodiment, by setting a guide rod 10, the movement trajectory of the pressure plate 4 is limited, making its vertical movement more stable.

[0058] Preferably, in another embodiment of the present invention, the vertical drive motor further includes:

[0059] Two protective plates 11 are respectively disposed on both sides of the pressure plate 4 and connected to the gantry 5.

[0060] In this embodiment, protective plates 11 are provided on both sides of the pressure plate 4 to isolate the pressure plate 4 from the outside world and prevent foreign objects from entering. To facilitate observation of the implementation of the pressure plate 4, the protective plates 11 can be made of transparent acrylic sheets.

[0061] Preferably, in another embodiment of the present invention, the horizontal drive mechanism includes:

[0062] A linear track 12 is provided on the upper end of the operating table 1, and the mounting platform 2 is slidably provided on the linear track 12;

[0063] A connecting block is provided at the lower middle part of the mounting platform 2, and the operating platform 1 is provided with a notch corresponding to the connecting block, and the connecting block vertically penetrates the notch;

[0064] The second cylinder 13 is located at the lower end of the operating table 1. Its push rod is parallel to the linear track 12 and connected to the connecting block. The second cylinder 13 is connected to the air supply assembly. The air supply assembly also includes: a second vacuum generator, whose inlet is connected to the outlet of the air source filter 7; and a second solenoid valve, whose inlet is connected to the outlet of the second vacuum generator and whose outlet is connected to the inlet of the second cylinder 13.

[0065] In this embodiment, a second power unit is formed by the air source filter 7, the second vacuum generator, and the second solenoid valve. By controlling the states of the second vacuum generator and the second solenoid valve, the second power unit supplies or evacuates air from the second cylinder 13, thereby extending or retracting the push rod of the second cylinder 13. The connecting block drives the mounting platform 2 to move on the linear track 12. The first vacuum generator 8 and the second vacuum generator are arranged side by side, as are the first solenoid valve 9 and the second solenoid valve (not shown in the attached drawings).

[0066] Preferably, as another embodiment of the present invention, it further includes:

[0067] Two limiting members 14 are provided on the operating table 1 and located on both sides of the mounting table 2 respectively. When the mounting table 2 moves to the feeding position and the pressure holding position, its two ends abut against the two limiting members 14 respectively.

[0068] In this embodiment, two limiting members 14 are set to control the horizontal movement trajectory of the mounting platform 2 and prevent it from derailing.

[0069] Preferably, in another embodiment of this utility model, the positioning detection mechanism includes:

[0070] Two position sensors 3 are spaced apart on the operating table.

[0071] In this embodiment, such as Figure 5 As shown, the two position sensors 3 correspond to the loading position and the pressure holding position, respectively. Sensing blocks are installed on the mounting platform 2, and the detection parts of the two position sensors 3 are located on the moving trajectory of the sensing blocks. The distance between the loading position and the pressure holding position is greater than the length of the mounting platform 2, ensuring that the two position sensors 3 cannot detect the sensing blocks simultaneously. The position sensors 3 also employ limit switches.

[0072] Preferably, as another embodiment of the present invention, it further includes:

[0073] Two start switches 15 are respectively located on both sides of the operating panel 1. The two start switches 15 are connected to the circuit of the bending and pressure-holding device.

[0074] In this embodiment, a single start switch 15 is generally used. However, in this embodiment, since the bending and pressure-holding device operates completely automatically, a dual start switch 15 mode is adopted to prevent accidental activation. The bending and pressure-holding device will only start working when both start switches 15 are pressed simultaneously.

[0075] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
