Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic component processing, in particular to a multi-station rotatable material waiting device for an electronic component digital factory and a dispensing method. BACKGROUND

[0002] At present, inductance coils play an extremely important role in various circuit systems and are widely used. On the market, there is an inductance coil which is wound on a circular ring by a pair of coils one by one. The circular ring is an insulating tube so that the coils are insulated from each other. After winding a certain number of turns, four pins are led out. In order to increase the inductance, an iron core or a magnetic powder core is usually arranged in the inner cavity of the circular ring. This inductance coil is divided into three categories according to the shape, i.e. inductance coil without base and without bottom plate, inductance coil with base and inductance coil with bottom plate.

[0003] In the prior art, as shown in the inductance coil with base shown in Figure 1 , the circular ring wound with the coil needs to be fixedly connected with the base during production and processing. The existing fixing method is mainly to perform dispensing by a dispensing machine (the dispensing position is shown by the black dot in Figure 1 ), i.e. to perform dispensing around the contact surface of the inductance coil and the base. In order to realize automatic dispensing, the inductance coil to be dispensed usually needs to be placed on a material waiting mechanism. The existing material waiting mechanism can only place one product (inductance coil) at a time, i.e. single dispensing during dispensing, and the efficiency is relatively low. If multiple products are placed on the material waiting mechanism, how to make the multiple products rotate synchronously is a problem to be solved urgently. SUMMARY

[0044] Embodiment 2 (not shown)

[0045] The structure of the embodiment is basically the same as that of the embodiment 1, with the difference that the synchronous structure comprises a driving gear arranged on the output shaft of the rotating motor and a driven gear arranged on the material waiting seat, and the driving gear and the driven gear are driven by a chain; in the embodiment, the number of the material waiting seats can be multiple (two or more) and arranged along the length direction of the turnover support, and the driving gear on the output shaft of the rotating motor can be located at the end and drive the driven gear on the material waiting seat by the chain; at this time, the output shaft of the rotating motor drives the driving gear to rotate, the driving gear drives the driven gear on the material waiting seat to rotate by the chain, and the material waiting seat is synchronously rotated.

[0046] In order to enable the material waiting seat 10 to be assembled on the turnover support 2 and rotate in place, various structural forms can be adopted as easily thought by those skilled in the art, however, in order to facilitate implementation, the present application preferably adopts the following structural form:

[0047] As shown in Figures 2-4 , the turnover support 2 is provided with an axle hole, the axle hole is provided with a bearing 7, the lower part of the material waiting seat 10 is provided with a central shaft 9 inserted into the inner hole of the bearing 7, and the driven gear 8 is mounted on the central shaft 9. In order to facilitate the assembly of the central shaft 9 and the bearing 7, the central shaft 9 can sequentially comprise a positioning boss section 91 matched with the lower end surface of the bearing 7, a bearing mounting shaft section 92 matched with the inner hole of the bearing 7, and a gear mounting shaft section 93 for mounting the driven gear 8 from bottom to top (i.e. from left to right in the middle). Figure 4 The above-mentioned bearing 7, central shaft 9 and driven gear 8 are assembled by first embedding the bearing 7 in the axle hole on the turnover support 2, then passing the central shaft 9 through the inner hole of the bearing 7, and tightly pressing the positioning boss section 91 of the central shaft 9 and the lower end surface of the bearing 7, and then sleeving the driven gear 8 on the gear mounting shaft section 93 of the central shaft 9, so that the lower end surface of the driven gear 8 is matched with the upper end surface of the bearing 7 and can be fastened by a top screw.

[0048] As shown in Figure 2 , in order to place the to-be-glued inductor coil, the upper end of the material waiting seat 10 can be provided with a recess 101 for placing the to-be-glued inductor coil, and the recess 101 is provided with a pin insertion hole 102 for accommodating the pins of the to-be-glued inductor coil. In order to prevent the to-be-glued inductor coil from falling off the material waiting seat 10, a window 103 extending along the length direction of the recess 101 can be provided below the recess 101 on the material waiting seat 10, and the window 103 is provided with a magnet (not shown) for adsorbing the inductor coil.

[0049] The turnover driving device in the present application preferably adopts the following structural form:

[0050] As shown in Figure 2As shown, a flipping motor base can be provided on one side of the flipping bracket 2 along its length. The flipping drive device is a flipping motor 1 mounted on the flipping motor base, and the output shaft of the flipping motor 1 drives and connects to the flipping bracket 2. When the output shaft of the flipping motor 1 rotates, it can drive the flipping bracket 2 to flip, thereby causing the material holder 10 located on the flipping bracket 2 to flip to the dispensing station. The flipping motor base can include a horizontal fixed base plate 4 and a vertical fixed upright plate 3. In this case, the flipping motor base is preferably L-shaped, and the flipping motor 1 can be fixed on the fixed upright plate 3. The output shaft of the flipping motor 1 passes through the fixed upright plate 3 and drives and connects to the flipping bracket 2.

[0051] The material receiving seat 10 is preferably located on the center line of the flipping bracket 2 along its length; the axis of the output shaft of the flipping motor 1 is preferably on the same straight line as the center line of the flipping bracket 2 along its length, which facilitates the flipping motor 1 to drive the flipping bracket 2 to flip. To protect the synchronization structure, the flipping bracket 2 may be provided with a gearbox 12 to hide the synchronization structure.

[0052] To detect whether the inductor coil to be dispensed has been placed on the material holder 10 during the dispensing process, the present invention can have the following structural form:

[0053] Structural Form 1: such as Figure 5 As shown, an L-shaped sensor bracket 13 can be provided on the flip motor base (i.e., the fixed upright plate 3). The vertical part of the sensor bracket 13 is fixed on the flip motor base, and the horizontal part of the sensor bracket 13 is provided with an infrared sensor 14 opposite to the material stand 10 for detecting whether the inductor coil to be dispensed has been placed on the material stand. Specifically, the transmitting end and the receiving end of the infrared sensor 14 can be an integral structure and are both located on the horizontal part of the sensor bracket 13. When the infrared sensor 14 is working, the transmitting end emits infrared light above the material stand 10. When there is an inductor coil to be dispensed on the material stand 10, the inductor coil to be dispensed reflects the infrared light to the receiving end, and the infrared sensor 14 can know that the inductor coil to be dispensed has been placed on the material stand 10; otherwise, it has not been placed. In the embodiment shown in the figure, there are two material stands 10 and two infrared sensors 14.

[0054] Structure Form Two (not shown): An infrared sensor for detecting whether the inductor coil to be dispensed has been placed on the material holder can be provided in the groove 101. The transmitting end of the infrared sensor is located on one side wall of the groove 101, and the receiving end is located on the other side wall of the groove 101. When the infrared sensor is working, the transmitting end emits infrared light to the receiving end. When the inductor coil to be dispensed is placed on the material holder (i.e., there is an inductor coil to be dispensed in the groove 101), the inductor coil to be dispensed blocks the infrared light emitted by the transmitting end to the receiving end. The infrared sensor can then know that the inductor coil to be dispensed has been placed on the material holder. Otherwise, it has not been placed.

[0055] To detect the rotational position of the material holder 10 during the dispensing process, the present invention can have the following structural form:

[0056] Structural Form Three: such as Figure 5 As shown, a first vertical plate 15 can be provided on the side of one of the waiting seats 10 on the flipping bracket 2. The first vertical plate 15 has a U-shaped opening on the side facing the waiting seat 10. An infrared sensor for detecting the rotation position (initial position, i.e., zero position) of the waiting seat 10 is provided in the U-shaped opening. The emitting end of the infrared sensor is located on one side wall of the U-shaped opening, and the receiving end is located on the other side wall of the U-shaped opening. The waiting seat 10 is provided with a first baffle 17 that extends outward (i.e., away from the axis of the waiting seat 10) and can enter the U-shaped opening after the waiting seat 10 rotates. When the infrared sensor is working, the emitting end emits infrared light to the receiving end. When the waiting seat 10 rotates, when the first baffle 17 on it is located in the U-shaped opening of the first vertical plate 15, the first baffle 17 blocks the infrared light emitted by the emitting end to the receiving end. The infrared sensor can then know that the position of the waiting seat 10 is in the initial position, and vice versa.

[0057] Structure Form 4: The flip bracket 2 can be equipped with an infrared sensor for detecting the rotation position of the waiting seats. The transmitting end of the infrared sensor is located in the window 103 of one of the waiting seats 10, and the receiving end is located in the window 103 of the adjacent waiting seat 10. When the infrared sensor is working, the transmitting end emits infrared light. When the receiving end receives the infrared light, the infrared sensor can know that the positions of the two waiting seats are in the initial position, otherwise they are not in the initial position.

[0058] To facilitate the detection of the rotational position of the flipping bracket 2, a second vertical plate 19 can be provided on the flipping motor base (i.e., the fixed upright plate 3). The second vertical plate 19 has a U-shaped opening on the side facing the output shaft of the flipping motor 1. An infrared sensor for detecting the rotational position of the flipping bracket 2 is provided in the U-shaped opening. The emitting end of the infrared sensor is located on one side wall of the U-shaped opening, and the receiving end is located on the other side wall of the U-shaped opening. The output shaft of the flipping motor 5 is provided with a second baffle 18 that extends outward (i.e., away from the axis of the flipping motor 5) and can enter the U-shaped opening after the output shaft rotates. When the infrared sensor is working, the emitting end emits infrared light to the receiving end. When the output shaft of the flipping motor 5 rotates, and the second baffle 18 is located in the U-shaped opening of the second vertical plate 19, the second baffle 18 blocks the infrared light emitted by the emitting end to the receiving end. The infrared sensor can then know that the position of the flipping bracket 2 is in the initial position, and vice versa.

[0059] On the other hand, the present invention provides a method for dispensing adhesive using the above-mentioned multi-station rotatable material receiving device in a digital factory for electronic components, the method comprising:

[0060] Step 1: When the to-be-glued inductor coil is placed on the to-be-material seat 10, the turnover driving device drives the turnover support 2 to turn clockwise by 90 degrees from the zero position, and when the turnover support 2 is turned by 90 degrees, the glue dispensing valve of the glue dispenser moves from the initial to-be-material position to the glue dispensing position, and the first face of the to-be-glued inductor coil starts to be glued;

[0061] In this step, after the device is powered on, the turnover support 2 and the to-be-material seat 10 can be reset to the zero position. When the infrared sensor 14 on the sensor support 13 senses that there is a to-be-glued inductor coil on the to-be-material seat 10, the turnover driving device starts to work again. The specific operation process of resetting the turnover support 2 and the to-be-material seat 10 to the zero position can be as follows:

[0062] The output shaft of the turnover motor 1 rotates, so that the second baffle 18 on the output shaft of the turnover motor 1 is located in the U-shaped opening of the second vertical plate 19 on the fixed vertical plate 3, thereby resetting the turnover support 2 to the zero position; the output shaft of the rotation motor 5 rotates, so that the first baffle 17 on the output shaft of the rotation motor 5 is located in the U-shaped opening of the first vertical plate 15 on the turnover support 2, thereby resetting the to-be-material seat 10 to the zero position;

[0063] Step 3: When the first face of the to-be-glued inductor coil is glued, the rotation motor 5 of the rotation driving device drives the to-be-material seat 10 to rotate synchronously by 90 degrees clockwise through the synchronous structure, and when the to-be-material seat 10 is rotated by 90 degrees, the second face of the to-be-glued inductor coil starts to be glued;

[0064] Step 4: When the second face of the to-be-glued inductor coil is glued, the rotation motor 5 of the rotation driving device drives the to-be-material seat 10 to rotate synchronously by 90 degrees clockwise again through the synchronous structure, and when the to-be-material seat 10 is rotated by 90 degrees, the third face of the to-be-glued inductor coil starts to be glued;

[0065] Step 5: When the third face of the to-be-glued inductor coil is glued, the rotation motor 5 of the rotation driving device drives the to-be-material seat 10 to rotate synchronously by 90 degrees clockwise again through the synchronous structure, and when the to-be-material seat 10 is rotated by 90 degrees, the fourth face of the to-be-glued inductor coil starts to be glued;

[0066] Step 6: When the fourth face of the to-be-glued inductor coil is glued, the glue dispensing valve of the glue dispenser returns to the initial to-be-material position, and when the glue dispensing valve returns to the initial to-be-material position, the turnover driving device drives the turnover support 2 to return to the zero position, and the to-be-glued inductor coil is glued, and the inductor coil is removed;

[0067] In this step, after the inductor coil is removed, the zero point calibration can be performed by driving the turnover bracket 2 with the turnover motor 1 (refer to step 1), after the turnover bracket 2 completes the zero point calibration, the zero point calibration can be performed by driving the material waiting seat 10 with the rotating motor 5 (refer to step 1), after the material waiting seat 10 completes the zero point calibration, the next group of products (inductor coils to be glued) can be produced.

[0068] The above is the preferred embodiment of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
