Description

Technical Field

[0001] The utility model relates to the technical field of ear-hook type Bluetooth earphones, in particular to an ejection device for the ear-hook type Bluetooth earphone after the ear-hook is formed. Background Art

[0002] In recent years, as many mobile phone manufacturers have begun to abandon the headphone jack on their mobile phones, Bluetooth headsets have been widely used in smart devices and smart communications, especially ear-hook Bluetooth headsets.

[0003] Existing Bluetooth headsets are roughly divided into two categories: one is an in-ear Bluetooth headset in which the sound element is worn inside the user's ear canal when in use; the other is an open-type Bluetooth headset in which the sound element is worn outside the user's ear canal to produce sound. This open-type Bluetooth headset is also called an earhook Bluetooth headset.

[0004] Since the transmitter of the ear-hook Bluetooth headset is suspended outside the user's ear canal, the ear-hook Bluetooth headset cannot be worn through the user's ear canal as an auxiliary. Therefore, general ear-hook Bluetooth headsets require an ear hook for auxiliary wearing to be provided on the headset body.

[0005] After the existing ear hooks are formed on the mold core, they are usually separated manually. However, due to the manual separation, the ear hooks are easily damaged after separation. Moreover, the labor cost is high and the efficiency is low.

[0006] Therefore, it is necessary to develop a new technical solution to solve the above problems. Utility Model Content

[0007] The present invention aims to overcome the deficiencies in the above-mentioned prior art and its main purpose is to provide an ejection device for the ear hook of an ear hook type Bluetooth headset after it is molded. The device can separate the injection molded ear hook from the mold core, thereby improving the separation effect and the quality rate of the product. Moreover, the device has a high degree of intelligence and reduces labor costs.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0009] An ejection device for an earhook of an earhook type Bluetooth headset after the earhook is formed, comprising a frame and an ejection device body arranged on the frame;

[0012] The bearing block, the first separation mechanism, the second separation mechanism, the air blowing cooling mechanism and the third separation mechanism are all arranged on the frame;

[0013] The device further comprises a main control unit, which is respectively connected to the first separation mechanism, the second separation mechanism, the air blowing cooling mechanism and the third separation mechanism.

[0046] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 9 As shown, an ejection device for an earhook of an earhook type Bluetooth headset after the earhook is formed comprises a frame 10 and an ejection device body 20 disposed on the frame 10;

[0048] The left and right sides of the frame 10 can be rotatably connected with a handle 11 for storage or use. When the handle 11 is not in use, it can save space and avoid the handle 11 from causing harm to the human body.

[0049] The frame 10 has a horizontal workbench 12, on which the ejector body 20 is mounted. In this embodiment, a plurality of ejector bodies 20 are provided, spaced apart in the horizontal direction on the horizontal workbench 12. The four ejector bodies 20 can operate simultaneously, significantly improving ejection efficiency.

[0050] The ejection device body 20 includes a supporting block 30 for placing a mold core 82 with an injected ear hook 81, a first separation mechanism 40 for moving the insert 83 on the mold core 82 on the supporting block 30 downward to separate the first buckle position of the injected ear hook 81 from the insert 83, a second separation mechanism 50 for separating the second buckle position of the injected ear hook 81 on the mold core 82 on the supporting block 30 from the mold core 82, an air blowing cooling mechanism 60 for blowing air to cool the injected ear hook 81 on the mold core 82 on the supporting block 30, and a third separation mechanism 70 for completely separating the injected ear hook 81 on the mold core 82 on the supporting block 30 from the mold core 82.

[0051] The bearing block 30, the first separation mechanism 40, the second separation mechanism 50, the air blowing cooling mechanism 60 and the third separation mechanism 70 are all arranged on the frame 10;

[0052] The main control unit is further included, and the main control unit is connected to the first separation mechanism 40, the second separation mechanism 50, the air blowing cooling mechanism 60 and the third separation mechanism 70 respectively.

[0053] In this embodiment, the ejector body 20 further includes a control switch 21, with each control switch 21 configured for one ejector body 20. The control switch 21 is mounted on the frame 10 and is connected to a main control unit. Pressing the control switch 21 activates the main control unit to control the operation of the first separation mechanism 40, the second separation mechanism 50, the air cooling mechanism 60, and the third separation mechanism 70.

[0054] The upper end surface of the horizontal workbench 12 is connected to a bracket 13 with an opening facing downward. The air blowing cooling mechanism 60 is disposed on the bracket 13 and is located above the bearing block 30 .

[0055] In this embodiment, the air blowing cooling mechanism 60 includes an air blowing cooling head 61, an extension block 62 and an air supply unit for providing a cold air source. The air supply unit is respectively connected to the main control unit and the air blowing cooling head 61. The air blowing cooling head 61 is connected to one end of the extension block 62, and the other end of the extension block 62 is connected to the bracket 13.

[0056] In this embodiment, the first separation mechanism 40 includes a first separation member 41 and a first driving cylinder 42 that drives the first separation member 41 to reciprocate in the front-to-back direction. The first driving cylinder 42 is located behind the bearing block 30.

[0057] The first separating member 41 is formed with a separating inclined surface 411 for cooperating with the inclined surface 831 of the insert 83 on the mold core 82 on the carrier block 30. The first driving cylinder 42 drives the first separating member 41 to extend into the carrier block 30 and move forward, causing the separating inclined surface 411 to abut against the inclined surface 831 of the insert 83 on the mold core 82 on the carrier block 30 and drive the insert 83 on the mold core 82 on the carrier block 30 to move downward. The first separating mechanism 40 is located behind the carrier block 30 and converts the linear force of the first driving cylinder 42 in the front-to-back direction into linear force in the vertical direction. This allows the first driving cylinder 42 to be installed horizontally, does not occupy too much vertical installation space, and does not affect the normal operation of the air blowing cooling mechanism, which is beneficial to the ejection effect.

[0058] A groove 121 is formed downwardly on the upper end surface of the horizontal workbench 12 for connecting to the interior of the frame 10. The second separation mechanism 50 and the third separation mechanism 70 are both obliquely arranged beside the supporting block 30. Parts of the second separation mechanism 50 and the third separation mechanism 70 are installed inside the frame 10 through the groove 121.

[0059] Next, the working principle is briefly explained: first, the mold core 82 with the molded ear hook 81 that has completed the injection molding task is placed on the supporting block 30, and then the first separation mechanism 40, the air blowing cooling mechanism 60, the second separation mechanism 50 and the third separation mechanism 70 are controlled in sequence to complete the demolding of the molded ear hook 81.

[0060] The key points of the design of the utility model are: it can separate the injection-molded ear hook from the mold core mainly through the cooperation of the supporting block, the first separation mechanism, the second separation mechanism, the blowing cooling mechanism and the third separation mechanism, thereby improving the separation effect and the quality rate of the product, and the degree of intelligence is high, which reduces labor costs.

[0061] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
