It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model; the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; in addition, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two devices. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] Currently, for small-rate devices such as buttons in a Bluetooth transmitter, the devices are usually hot-pressed and fixed on the housing of the Bluetooth transmitter by manual operation. Since manual operation cannot control the reasonable pressure magnitude, there is a risk of damaging the devices, and the hot-pressing effects are uneven, resulting in unstable product quality.

[0027] To solve the above technical problems, this embodiment provides a hot-pressing and ironing point device. Please refer to Figure 1 and Figure 2 , the hot-pressing and ironing point device includes a bottom plate 1, a pressure sensor, and a controller. A fixing frame 2 is fixed on the bottom plate 1, and the height direction of the fixing frame 2 is perpendicular to the plate surface of the bottom plate 1.

[0028] A telescopic mechanism 3 is installed on the fixing frame 2, and a pressing block 4 is connected to the power output end of the telescopic mechanism 3. Optionally, the telescopic mechanism 3 can use a cylinder, an oil cylinder, an electric cylinder, a motor, etc. as the power source. The bottom of the pressing block 4 is detachably connected with a pressing head 5 to facilitate the replacement of different pressing heads 5.

[0029] The pressing head 5 of this embodiment is made of a heat-conducting material (such as copper or aluminum). A heating module (not shown in the figure) is provided inside the pressing head 5. A hot-pressing ejector pin 51 is arranged at the bottom of the pressing head 5. The heat on the heating module can be transmitted to the device pressed by the pressing head 5 through the hot-pressing ejector pin 51, so as to realize the heating effect on the device. The heating module is electrically connected to the controller and the power supply through wires, and electric heating is carried out by energizing the heating module.

[0030] A pressing seat 6 is installed on the bottom plate 1 at the position corresponding to the lower part of the pressing head. Please refer to Figure 3, a receiving groove 61 for placing the device to be heat-pressed is provided on the pressing seat 6, and the shape of the receiving groove 61 matches the shape of the housing m. The pressure sensor can be selectively installed on the pressing block 4, the pressing head 5 or the pressing seat 6, and is used to detect the pressure applied by the pressing head 5 to the device in real time, and feed back the detected pressure data to the controller.

[0031] Both the pressure sensor and the telescopic mechanism 3 are electrically connected to the controller. Thus, the controller can control the operation of the telescopic mechanism 3 according to the pressure data fed back by the pressure sensor, so as to control the pressing force of the pressing head 5 on the device within a preset appropriate range.

[0032] The hot pressing and spotting device of this embodiment further includes a timing module g, and the timing module g is electrically connected to the controller. The controller controls the duration of the pressing head 5 pressing the device to be heat-pressed according to the signal fed back by the timing module g.

[0033] A control box 7 is also fixed on the bottom plate 1. The controller and the timing module g are arranged on the control box 7. A power switch h is also arranged on the control box 7. Operating the power switch h can control the conduction or disconnection of the device from the external power supply.

[0034] After the housing m is placed in the receiving groove 61, the power switch h of the device is started, and the telescopic mechanism 3 drives the pressing head 5 to descend, pressing the device placed on the housing m. When the pressure detected by the pressure sensor reaches the set appropriate value, the controller controls the telescopic mechanism 3 to stop descending and maintain the current position. The heating module is powered on for electric heating, and the hot pressing ejector pin 51 of the pressing head 5 presses the component and performs hot pressing. The timing module g calculates the duration of the pressing head 5 pressing the device. When the duration reaches the preset duration, the controller controls the telescopic mechanism 3 to drive the pressing head 5 to rise to release the device.

[0035] It can be seen that the device of this embodiment can control the downward pressing force and the downward pressing duration of the pressing head 5 on the device, so that both the downward pressing force and the downward pressing duration can be controlled and stabilized within an appropriate range. Thus, it can avoid damaging the device due to excessive downward pressing force or burning out the device due to too long downward pressing time; it can also avoid too small force or insufficient downward pressing time, resulting in insecure connection of the device. It can be seen that applying the device of this embodiment to the device hot pressing operation can not only prevent damage to the device, but also ensure the unity of the hot pressing effect, which is beneficial to improving the consistency of the product.

[0036] In some preferred embodiments, a flip cover 9 is connected to the pressing seat 6 through a hinge 8 (such as a hinge). When the flip cover 9 is flipped to the position where it covers the pressing seat 6, the flip cover 9 can press the device to be heat-pressed to prevent the device from shifting during the hot pressing process. An avoidance opening 91 is provided at a position corresponding to directly below the pressing head 5 on the flip cover 9, and the hot pressing ejector pin 51 on the pressing head 5 passes through the avoidance opening 91 to press the device to be heat-pressed.

[0037] In some preferred embodiments, a slide rail a is fixed on the base plate 1, the bottom of the pressure seat 6 is detachably connected to a pressure seat connecting plate b, the bottom of the pressure seat connecting plate b is connected to a slider c, the slider c is slidably installed on the slide rail a, and the pressure seat 6 can slide along the length direction of the slide rail a, so that the relative position of the pressure seat 6 and the pressure head 5 can be adjusted, so that the pressure head 5 can press different positions on the device, or can fix the device at different positions of the shell m.

[0038] In some preferred embodiments, an elastic toggle switch d is installed on the bottom plate 1, and the elastic toggle switch d is electrically connected to the controller and the heating module; when the pressing seat 6 is pushed to slide to the position directly below the pressing head 5, the pressing seat 6 can contact the elastic toggle switch d and trigger the elastic toggle switch d. After the elastic toggle switch d is triggered, the in-position signal of the pressing seat 6 is sent to the controller. After the controller receives the in-position signal of the pressing seat 6, it controls the telescopic mechanism 3 to drive the pressing head to press down 5 and start the heating module to heat. Furthermore, the elastic toggle switch d is detachably installed on the bottom plate 1, and in combination with the position adjustment of the pressing seat 6, the pressing head 5 can press different positions on the device without replacing the pressing head 5, or the device can be fixed at different positions of the housing m.

[0039] In some preferred embodiments, a magnetic patch e is fixed on the bottom plate 1 near the elastic toggle switch d, and a magnet is fixed on the outer surface of the pressure seat 6 near the elastic toggle switch d. The magnetic attraction between the magnet and the magnetic patch e facilitates the positioning and stabilization of the pressure seat 6.

[0040] In some preferred embodiments, a guide rod f is provided on the fixing frame 2, and a through hole is provided on the pressing block 4. The guide rod f is inserted into the through hole, and the guide rod f can guide and limit the pressing block 4. Therefore, the pressing block 4 can slide stably along the height direction of the guide rod f during the lifting process, and at the same time, it is also beneficial to the stability of the pressing head 5 when pressing the device, and prevents the pressing head 5 from swinging.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
