Description

Technical Field

[0001] The present invention relates to the technical field of glue sealing equipment, and in particular to an automatic glue sealing equipment. Background Art

[0002] See also Figure 1 Many products to be sealed 1 need to be heated appropriately when they are bonded with adhesives, etc., so as to enhance the bonding effect. For example, when the component to be bonded 102 is to be bonded to the main component 101, the steps are as follows:

[0003] ① Place the main component 101 into the fixture for fixing;

[0004] ② Applying adhesive to the main body part 101;

[0005] ③ Place the component to be bonded 102 on the main component 101;

[0006] ④ The heating device 2 on the sealing device presses down the component 102 to be bonded, and heats the component 102 to be bonded at the same time. After a certain period of time, the adhesive is solidified and the sealing is completed.

[0007] In the above process, generally, the temperature of each part of the heating device 2 is equal, so the temperature of the edge position 1021 and the middle position 1022 of the to-be-bonded component 102 is also approximately equal. However, some products such as smart watches often require that the temperature of the middle position 1022 of the to-be-bonded component 102 is slightly lower than the temperature of the edge position 1021. In this case, the traditional sealing equipment cannot meet such temperature requirements.

[0065] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] In the description of the present invention, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally disposed component. When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally disposed component.

[0067] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0068] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0069] See also Figure 2 to Figure 6This embodiment provides an automated sealing device including a jig assembly 3, a heating device 2, a heat dissipation metal block 4 and a heat dissipation fan 5. The jig assembly 3 is used to fix the product to be sealed with glue. The heating device 2 is used to press and heat the edge position of the product to be sealed with glue, and a through groove is provided in the middle thereof. The lower end of the heat dissipation metal block 4 extends into the through groove to fit with the middle position of the product to be sealed with glue. The heat dissipation fan 5 is located above the heat dissipation metal block 4 and is used to dissipate heat from the heat dissipation metal block 4.

[0070] Preferably, one end of the heat dissipation metal block 4 close to the heat dissipation fan 5 is a heat dissipation fin structure 401 , so as to optimize the heat dissipation speed of the heat dissipation metal block 4 .

[0071] The present embodiment provides an automated sealing device. After the product to be sealed is placed on the jig assembly 3, the heating device 2 presses the edge of the product to be sealed and heats the edge. The lower end of the heat dissipation metal block 4 is attached to the middle of the product to be sealed and brings the heat of the middle of the product to be sealed to the upper end of the heat dissipation metal block 4. Finally, this part of the heat is taken away by the heat dissipation fan 5, so that the temperature of the edge of the product to be sealed is higher than the temperature of the middle.

[0072] Optionally, the heating device 2 includes a heat-conducting silicone rubber 201, a heat-conducting plate 202 and a heating wire 203. The heat-conducting silicone rubber 201 is located directly above the edge of the product to be sealed. The heat-conducting plate 202 is fixedly connected to the heat-conducting silicone rubber 201. The heating wire 203 is located above the heat-conducting plate 202 and is in contact with the heat-conducting plate 202, and is used to transfer heat to the heat-conducting silicone rubber 201 through the heat-conducting plate 202.

[0073] Specifically, the heating wire 203 generates heat at a point, which easily leads to a high local temperature. The heat conducting plate 202 is arranged between the heating wire 203 and the heat conducting silicone 201 so that the heat generated by the heating wire 203 is first conducted through the heat conducting plate 202, and the temperature of each part of the heat conducting plate 202 is similar, thereby making the heat conducting silicone 201 evenly heated. Furthermore, using the heat conducting silicone 201 to directly contact the product to be sealed can avoid damaging the product to be sealed.

[0074] Furthermore, the heating device 2 further comprises a middle frame 204, a pressing plate 205 and an upper cover 206. The middle frame 204 is provided with an upper positioning groove at the top and a lower positioning groove at the bottom; the heat conducting plate 202 is fixed in the lower positioning groove. The pressing plate 205 is fixed in the upper positioning groove, and the heating wire 203 is located between the bottom of the upper positioning groove and the pressing plate 205. The upper cover 206 is fixed to the top of the middle frame 204.

[0075] Specifically, the middle frame 204 , the pressing plate 205 , the upper cover 206 and the like are all supporting structural members of the heating device 2 , and realize the relative fixation of the heat conducting plate 202 and the heating wire 203 .

[0076] In this embodiment, the automatic sealing device also includes a connecting component 6 and a driving mechanism 7 that drives the connecting component 6 to move up and down. The connecting component 6 is located above the heating device 2 and the heat dissipation metal block 4, and includes a vertical plate 601, a horizontal plate 602 and a rib plate 603. The vertical plate 601 is connected to the driving mechanism 7. The horizontal plate 602 is fixedly connected to the vertical plate 601, and a ventilation hole 6021 is provided at a position corresponding to the heat dissipation metal block 4. The rib plate 603 is located above the horizontal plate 602, and a mounting groove is provided in the middle thereof. The heat dissipation fan 5 is fixed in the mounting groove, and the heat dissipation metal block 4 is cooled through the ventilation hole 6021.

[0077] It is understandable that the connection assembly 6 can realize the relative fixation between the heating device 2 and the heat dissipation fan 5. When the product to be sealed needs to be placed in the fixture assembly 3, the driving mechanism 7 drives the connection assembly 6 to move upward to provide sufficient operating space. When the product to be sealed needs to be heated, the driving mechanism 7 drives the connection assembly 6 to move downward to facilitate the heating device 2 and the heat dissipation metal block 4 to fit the product to be sealed.

[0078] Furthermore, the connecting assembly 6 also includes a first guide post 604, a first buffer spring 605, a second guide post 606, and a second buffer spring 607. The lower end of the first guide post 604 is fixedly connected to the heating device 2, and the upper end is connected to the horizontal plate 602 for sliding up and down. The first buffer spring 605 is sleeved on the outside of the first guide post 604, and is used to drive the heating device 2 to slide downward relative to the horizontal plate 602. The upper end of the second guide post 606 is fixedly connected to the horizontal plate 602, and the lower end is connected to the heat dissipation metal block 4 for sliding up and down. The second buffer spring 607 is sleeved on the outside of the second guide post 606, and is used to drive the heat dissipation metal block 4 to slide downward relative to the horizontal plate 602.

[0079] When the heating device 2 moves downward, the heat dissipation metal block 4 stops moving downward after being attached to the product to be sealed, and the heating device 2 and the connecting component 6 continue to move downward and squeeze the second buffer spring 607; when the thermal conductive silicone 201 contacts the product to be sealed, the heating device 2 stops moving downward, and the connecting component 6 continues to move downward and squeeze the first buffer spring 605 until the first buffer spring 605 presses the heating device 2 against the product to be sealed. In this process, the first buffer spring 605 can press the thermal conductive silicone 201 against the edge of the product to be sealed, and the second buffer spring 607 can press the heat dissipation metal block 4 against the middle of the product to be sealed.

[0080] Optionally, the driving mechanism 7 includes a cylinder 701, a fixed plate 702 and a slide plate 703. The housing of the cylinder 701 is fixedly connected to the fixed plate 702. The slide plate 703 is connected to the fixed plate 702 in an upward and downward sliding manner under the driving of the driving end of the cylinder 701.

[0081] In this embodiment, when the driving end of the cylinder 701 extends, the slide plate 703 slides downward, and when the driving end of the cylinder 701 retracts, the slide plate 703 slides upward. Of course, in some other embodiments, a motor and a screw rod can also be used to drive the slide plate 703 to slide up and down.

[0082] A sliding limiter assembly is provided between the slide plate 703 and the connecting assembly 6, and the sliding limiter assembly includes a first guide rail 801, a first slider 802, and a first stopper 803. The first guide rail 801 is fixed to the lower end of the slide plate 703 in the vertical direction. One side of the first slider 802 is fixed to the connecting assembly 6, and the other side is slidably connected to the first guide rail 801. The first stopper 803 is fixed below the first slider 802 to prevent the first slider 802 from sliding further downward.

[0083] Furthermore, the automated sealing device also includes a pressure-maintaining component, which includes a counterweight 901, a second guide rail 902, a second slider 903, and a second limit block 904. The counterweight 901 is located above the connecting component 6, and is used to press the connecting component 6 downward. The second guide rail 902 is fixed to the upper end of the slide plate 703 in the vertical direction. One side of the second slider 903 is fixed to the counterweight 901, and the other side is slidably connected to the second guide rail 902. The second limit block 904 is fixed below the second slider 903, and is used to prevent the second slider 903 from continuing to slide downward.

[0084] It should be noted that when it is necessary to put the product to be sealed into the jig assembly 3, the driving mechanism 7 drives the slide plate 703 to move upward. Under the action of gravity, the connecting assembly 6 slides downward until it is blocked by the first limit block 803, and the counterweight block 901 slides downward until it is blocked by the second limit block 904. At this time, the counterweight block 901 does not contact the connecting assembly 6, that is, the counterweight block 901 does not apply pressure to the connecting assembly 6. When it is necessary to heat the product to be sealed, the driving mechanism 7 drives the slide plate 703 to move downward. When the heat dissipating metal block 4 and the thermal conductive silicone 201 press the product to be sealed, the connecting component 6 stops moving downward. The counterweight block 901 continues to move downward under the action of gravity until it fits with the rib plate 603 of the connecting component 6. The slide plate 703 continues to move downward, and the second limit block 904 no longer provides an upward supporting force for the counterweight block 901. Since the weight of the counterweight block 901 remains unchanged, the counterweight block 901 can apply a constant pressure to the connecting component 6, so that the product to be sealed can be bonded under the action of constant pressure.

[0085] It is understandable that by replacing the counterweight 901 with different weights, different pressures can be applied to the connecting assembly 6.

[0086] The working process of the automatic sealing equipment provided in this embodiment is as follows:

[0087] ① The driving end of the cylinder 701 retracts, and the heating device 2 and the counterweight 901 move upward;

[0088] ② Place the product to be sealed into the product slot 301 of the fixture assembly 3;

[0089] ③ The cylinder 701 drives the slide plate 703 to slide downward, and the counterweight block 901 applies downward pressure to the connecting assembly 6. First, the second buffer spring 607 presses the heat dissipation metal block 4 against the middle position of the product to be sealed, and then the first buffer spring 605 presses the thermal conductive silicone 201 against the edge position of the product to be sealed;

[0090] ④ Start the heating wire 203 to heat, and start the cooling fan 5 to cool the heat dissipation metal block 4;

[0091] ⑤ After a certain period of time, the sealing is completed, the driving end of the cylinder 701 is retracted, and the sealed product is taken out.

[0092] The automated sealing equipment provided in this embodiment can perform differentiated and precise control of the temperature of the heating area. By setting an optimized ventilation and heat dissipation structure, it can meet the active temperature of the glue at the edge position while not affecting the operation of other components in the middle position, thereby ensuring the stability of product quality.

[0093] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
