[0027] Currently, the housing of a Bluetooth transmitter is usually encapsulated by gluing two parts together. During the assembly process, in order to ensure the firm connection of the two parts of the housing, it is usually necessary to press and fix for a certain period of time after applying glue. With a large production volume on the production line, currently relying on manual operation one by one is not only slow and inefficient, but also difficult to unify the pressure-holding time, and the product quality is uneven, with poor consistency.

[0028] In view of the above technical problems, this embodiment provides a pressing device for a Bluetooth transmitter, which is used to press the two parts of the Bluetooth transmitter housing after dispensing glue. Please refer to Figure 1 , which is a schematic structural diagram of the pressing device; it includes a base 1, a bracket 2, a pressing unit 3, a timer 4, and a controller 5. Please refer to them together Figure 2 , the pressing unit includes a pressing power source 31, a pressing head 32, and a pressing seat 33. Preferably, the pressing power source 31 is an electric cylinder or a cylinder, and the free end of the telescopic rod of the electric cylinder or the cylinder is fixedly connected to the pressing head 32. It should be noted that in addition to using an electric cylinder or a cylinder as the power source, other mechanisms capable of outputting linear telescopic movement can also be used as the pressing power source.

[0029] The bracket 2 is fixed on the base 1, the pressing power source 31 is fixed on the bracket 2, and the pressing head 32 is fixedly connected to the free end of the telescopic rod of the pressing power source 31. The pressing seat 33 is fixed on the base 1 and is located directly below the pressing head 32. The pressing seat 33 is provided with a first receiving groove 331 for receiving the Bluetooth transmitter m. The timer 4 and the controller 5 are both arranged on the base 1. The controller 5 is electrically connected to the pressing power source 31. The controller can control the pressing power source 31 to drive the pressing head 32 to press down so as to press the housing of the Bluetooth transmitter m; the timer 4 is electrically connected to the controller 5. The timer can send time data to the controller 5 in real time. When the pressing time of the pressing head 32 pressing the housing of the Bluetooth transmitter m reaches the preset time, the controller 5 controls the pressing power source 31 to drive the pressing head 32 to rise so as to release the housing of the Bluetooth transmitter m.

[0030] The bottom surface of the pressing head 32 is provided with a second receiving groove 321. When the pressing head 32 abuts against the pressing seat 33, the first receiving groove 331 and the second receiving groove 321 together form a closed receiving cavity.

[0031] In order to improve work efficiency, the pressing device includes a plurality of pressing units 3. The number of the timer 4 and the controller 5 matches the number of the pressing units 3. The pressing power sources 31 in all the pressing units 3 are fixedly arranged on the bracket 2 side by side at intervals, and the pressing seats 33 in all the pressing units are fixedly arranged on the base 1 side by side at intervals.

[0032] Put the Bluetooth transmitter m after dispensing into the receiving groove 331, turn on the power supply, and the pressing power source 31 starts to drive the pressing head 32 to descend until the housing of the Bluetooth transmitter m is pressed. At this time, the timer 4 starts timing. At the same time, the pressing head 32 continuously presses the housing of the Bluetooth transmitter m. When the timing duration of the timer 4 reaches the set duration, a signal is sent to the controller 5, and the controller 5 controls the pressing head 32 to rise so as to leave the housing of the Bluetooth transmitter m. It can be seen that the pressing device of this embodiment can ensure that the two parts of the housing of the Bluetooth transmitter m have sufficient and appropriate pressing duration, the connection between the two parts of the housing is stable, and the unified pressure holding time can ensure the product quality and the consistency of the product quality. At the same time, due to the adoption of mechanized operation, the production efficiency is improved compared with manual operation.

[0033] In some preferred embodiments, the pressing unit 3 further includes a pressing head connecting block 34. The pressing head connecting block 34 is fixedly connected to the power output end of the pressing power source 31. The pressing head 32 is fixedly connected to the bottom surface of the pressing head connecting block 34 in a detachable manner. Therefore, different pressing heads 32 can be replaced as needed. The pressing unit 3 further includes a pressing seat connecting block 35. The pressing seat connecting block 35 is fixed on the base 1. The pressing seat 33 is fixedly connected to the top surface of the pressing seat connecting block 35 in a detachable manner. Therefore, different pressing seats 33 can be replaced as needed.

[0034] In some preferred embodiments, please refer toFigure 3 Moreover, a key avoidance groove 332 for avoiding the Bluetooth transmitter button is provided on the pressing seat 33. The key avoidance groove 332 is located on the side wall of the receiving groove 331. An antenna avoidance groove 333 for allowing the Bluetooth transmitter antenna to extend outwards is also provided on the pressing seat 33. One end of the antenna avoidance groove 333 communicates with the receiving groove 331, and the other end communicates with the outer surface of the pressing seat 33.

[0035] In some preferred embodiments, the area of the bottom surface of the pressing head 32 is larger than the area of the notch of the receiving groove 331. This design is beneficial to uniform pressure and large coverage area. The pressing head 32 can completely cover the outer shell to achieve sealed pressing and ensure the pressing effect.

[0036] In some preferred embodiments, a countersunk threaded hole 334 is further provided on the pressing seat 33. The pressing seat 33 is fixedly connected to the base 1 by installing a countersunk screw in the countersunk threaded hole 334. The head of the countersunk screw is lower than the top surface of the pressing seat 33 and will not cause spatial interference with the pressing head 32.

[0037] In some preferred embodiments, please refer to Figure 4 An elastic buffer pad 335 is provided at the bottom edge of the receiving groove 331. By providing the elastic buffer pad 335 at the bottom of the groove, on the one hand, it can play a buffering effect to avoid rigid contact between the outer shell and the bottom of the groove, which is beneficial to protecting the outer shell from being damaged by pressing; on the other hand, it can also make the pressure in the edge area tighter and optimize the pressing effect.

[0038] In some preferred embodiments, the timer 4 is installed on the base 1 and is electrically connected to the pressing power source 31. It can set the time and control the advancement and contraction of the telescopic rod of the pressing power source 31. There is a button switch 6 beside the timer 4, which is electrically connected to the pressing power source 31 and is used to control the start of the pressing power source 31 and the start of the timer 4. Each timer 4 is independently controlled. A control panel for displaying the time and setting the time (the control panel can be integrated with the timer 4) is provided on the outer surface of the base 1. After setting the time, press the button switch 6, the pressing power source 31 drives the pressing head 32 to press down tightly, and the display screen shows the time. After reaching the set time, the telescopic rod of the pressing power source 31 automatically contracts and resets.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
