Description

Technical Field

[0001] This application relates to the field of mechanical automation equipment technology, specifically to an adhesive bonding device for bonding and covering gasket components with adhesive tape. Background Technology

[0002] Fire sprinklers are important devices for fire prevention and control. Automatic sprinklers, due to their automatic sensing and spraying functions, play an even more important role in fire prevention and control.

[0003] Currently, most automatic sprinklers are controlled by electrical signals from temperature-sensitive or infrared sensors. These types of sprinklers suffer from defects such as signal failure and misidentification. However, there is another type of automatic sprinkler on the market that does not require sensors. It uses a combination of a thermoplastic gasket and temperature-sensitive tape to form a water valve seal. When the temperature reaches a threshold, the temperature-sensitive tape melts, and the gasket deforms, thus opening the seal and releasing the spray.

[0004] Because the gasket and the temperature-sensitive tape need to be precisely bonded, if there is stretching or deformation during the bonding process, it will lead to poor sealing. Therefore, the current production method is to apply tape to each gasket independently. This type of production method is less efficient, and individual finished products are not convenient for the subsequent automated production of sprayers.

[0005] Therefore, researching production equipment for precisely applying double-layer adhesive tape to gaskets to form rolls of material has become an urgent problem for those skilled in the art. Utility Model Content

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Furthermore, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure as shown in the attached drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the structure.

[0027] Please see Figures 1 to 16 One embodiment of this application provides a gasket overlay bonding device for bonding a gasket 200 between an upper adhesive tape 110 and a lower adhesive tape 120 to form a gasket as described above. Figure 16 The shown is a 100mm rubber-coated strip. Among them, such as... Figure 17 As shown, the washer 200 has an inner hole 210 at its center. In this embodiment, the washer 200 is made of metal. In other embodiments, the washer 200 may be made of other materials.

[0028] Combination Figure 1 refer to Figure 3 As shown in the present application, the gasket overmolding and bonding device includes a machine base 300, on which a tape conveying mechanism 1, a gasket feeding mechanism 2, a film pressing mechanism 5, a punching mechanism 7, a material tray mechanism 9, and a translation mechanism 10 are provided.

[0029] Specifically, the belt conveyor mechanism 1 includes a first belt conveyor assembly 101 for conveying the lower belt 120 and a second belt conveyor assembly 102 for conveying the upper belt 110, with the upper belt 110 located above the lower belt 120; a gasket feeding mechanism 2 is disposed between the first belt conveyor assembly 101 and the second belt conveyor assembly 102, and the gasket feeding mechanism 2 is used to pick up gasket parts 200 and place them one by one on the upper surface of the lower belt 120; a film pressing mechanism 5 is disposed in the second belt conveyor assembly. Between part 102 and the punching mechanism 7, the pressing mechanism 5 is used to press and adhere the lower tape 120 and the upper tape 110 so that the lower tape 120 and the upper tape 110 stick together the gasket part 200 to form the overmolded material tape 100; the punching mechanism 7 is located between the pressing mechanism 5 and the material tray mechanism 9, and the punching mechanism 7 is used to punch and cut the overmolded material tape 100; the material tray mechanism 9 is located at the rear end of the punching mechanism 7, and the material tray mechanism 9 is provided with a take-up roll 901, which receives the wound overmolded material tape 100.

[0030] In this application, the upper surface of the lower adhesive tape 120 is the adhesive surface, and the lower surface of the upper adhesive tape 110 is the adhesive surface.

[0031] The translation mechanism 10 periodically clamps the rubber-coated strip 100 and drives the rubber-coated strip 100 to translate.

[0032] Combination Figure 9 As shown, in one embodiment, the translation mechanism 10 includes a translation guide rail 1001, a translation driver 1002, a translation plate 1003, a translation stand 1004, and a plurality of translation clamps 1005 for clamping the rubber-coated strip 100. The translation plate 1003 is slidably disposed on the translation guide rail 1001. The translation driver 1002 is connected to the translation plate 1003 to drive the translation plate 1003 to translate relative to the translation guide rail 1001. The translation stand 1004 is fixedly connected to the translation plate 1003 to achieve synchronous translation. The translation clamps 1005 are connected to the translation stand. Each translation clamp 1005 is arranged side by side. The rubber-coated strip 100 passes through the clamping space of the translation clamp 1005. Furthermore, in order to coordinate with the cyclic clamping movement of the translation clamp 1005 in the translation mechanism 10, in this embodiment, the machine base 300 is provided with a number of positioning clamps 600. The positioning clamps 600 and the translation clamp 1005 are arranged side by side, and the rubber-coated strip 100 passes through the clamping space of the positioning clamp 600.

[0033] In this embodiment, the translation driver 1002 is a servo motor, which is connected to the translation plate 1003 through a screw transmission structure. The rotation of the screw drives the translation plate 1003 to reciprocate.

[0034] Combination Figure 9As shown, in this embodiment, the number of translation stands 1004 is consistent with the number of translation clips 1005, and each translation clip 1005 is connected to a corresponding translation stand 1004. In other embodiments, the number of translation stands 1004 may be one or less than the number of translation clips 1005, and one or more translation clips 1005 may be mounted on one of the translation stands 1004.

[0035] Specifically, in this embodiment, to save space and facilitate assembly, a mounting frame 400 is provided on the machine base 300, and the belt conveying mechanism 1, the washer feeding mechanism 2, the film pressing mechanism 5, the punching mechanism 7, and the material tray mechanism 9 are all mounted on the mounting frame 400. In other embodiments, the various mechanisms can be mounted on the same or different mounting brackets as needed.

[0036] In this embodiment, the positioning clip 600 is mounted on the mounting bracket 400.

[0037] Specifically, in this embodiment, both the translation clamp 1005 and the positioning clamp 600 employ pneumatic grippers. A pneumatic gripper is a conventional clamping actuator that includes a cylinder and grippers, using compressed air as power to drive the grippers to close and open. In other embodiments, other clamping actuators with clamping and releasing functions can also be used, such as hydraulic clamping mechanisms, magnetic clamping mechanisms, etc.

[0038] In existing tape transport solutions, most methods use a roller to pull the tape, which can achieve precise tape transfer. However, because tape itself has certain tensile deformation characteristics, the longer the tape, the greater the cumulative deformation at its rear end. For objects like the gasket-wrapped tape 100 processed in the embodiments of this application, the accumulated deformation stress can cause the finished tape to shrink after processing, greatly affecting product yield.

[0039] This application uses a translation mechanism 10 to clamp and move the overmolded material strip 100, and in conjunction with a positioning clamp 600, it can accurately move and position the overmolded material strip 100, avoiding deformation caused by tension.

[0040] Combination Figure 1 As shown, in order to facilitate the arrangement and conveying of scattered gasket parts 200 to the gasket feeding mechanism 2, the machine 300 is also provided with a gasket feeding mechanism 3 in this application. The gasket feeding mechanism 3 is connected to the gasket feeding mechanism 2. The gasket feeding mechanism 3 arranges the gasket parts 200 and moves them to the picking area of ​​the gasket feeding mechanism 2.

[0041] Combination Figure 2 , Figure 6 and Figure 7As shown, in this embodiment, the washer feeding mechanism 3 includes a vibratory feeder 301, a direct vibratory feeder 302, and a feeding turntable 303. The direct vibratory feeder 302 is connected between the vibratory feeder 301 and the feeding turntable 303, and the feeding turntable 303 is located in the material picking area of ​​the washer feeding mechanism 2.

[0042] Among them, the vibratory plate 301 and the direct vibratory feeder 302 are conventional material arrangement and conveying mechanisms, which can realize the vibration arrangement and conveying of scattered gasket parts 200.

[0043] And combined Figure 6 As shown, the feeding turntable 303 is a rotating disc with several feeding positions at equal intervals. The washer parts 200 conveyed by the direct vibration feeder 302 can be clamped at the feeding position and rotated to the picking area, so that the washer feeding mechanism 2 can pick up the material.

[0044] Combination Figure 6 and Figure 7 As shown, in this embodiment, the gasket feeding mechanism 2 includes a feeding drive motor 201, a fixed plate 202, a rotating plate 203, a pressing drive cylinder 204, and several suction heads 205 for picking up and placing gasket parts 200. The feeding drive motor 201 is fixedly mounted on the fixed plate 202, with its rotation output end facing downwards. The rotating plate 203 is connected to the rotation output end of the feeding drive motor 201. The pressing drive cylinder 204 is fixedly mounted on the fixed plate 202 and located above the lower tape 120, with its telescopic end facing downwards. Each suction head 205 is vertically slidably sleeved onto the rotating plate 203 at intervals. The telescopic end of the pressing drive cylinder 204 matches the position of the suction head 205 to drive the suction head 205 to move downwards and place the picked-up gasket part 200 onto the lower tape 120.

[0045] In this embodiment, the downward drive cylinder 204 is a pneumatic telescopic cylinder, whose telescopic end can extend downward to move the suction head 205 downward to near the lower tape 120, and release the gasket 200 close to the lower tape 120.

[0046] In this embodiment, for the metal washer 200 with magnetic properties, the suction head 205 adopts a magnetic end structure, which can magnetically attract the washer 200. Then, under the action of the downward driving cylinder 204, the suction head 205, which has attracted the washer 200, is driven to approach the lower adhesive tape 120. Due to the adhesive effect of the lower adhesive tape 120, it can adhere to the washer 200. When the suction head 205 moves upward, the adhesive force is greater than the magnetic attraction force of the suction head 205 on the washer 200, so the washer 200 is placed on the adhesive surface of the lower adhesive tape 120.

[0047] In another embodiment, the suction head 205 can be a conventional negative pressure suction mechanism, which sucks up and releases the gasket 200 by controlling the negative pressure, thereby realizing the feeding action of the gasket 200.

[0048] Combination Figure 7 As shown, in order to reset the suction head 205, a compressed elastic element 206, such as a spring, is sleeved around the outer periphery of the suction head 205. One end of the elastic element 206 abuts against the blocking part of the suction head 205, and the other end abuts against the rotating plate 203. When the extension end of the downward-pressing pneumatic cylinder retracts, the suction head 205 will reset under the action of the elastic element 206.

[0049] Combination Figure 1 To ensure a tighter wrapping of the gasket 200 by the upper tape 110 and lower tape 120, a piercing mechanism 4 is provided between the tape conveying mechanism 1 and the film pressing mechanism 5 in this application. The piercing mechanism 4 can pierce the inner hole 210 of each gasket 200 on the tape 100 to expel internal air.

[0050] Specifically, in combination Figure 11 As shown, in this embodiment, the piercing mechanism 4 includes a first upper pressing cylinder 401, a first lower pressing cylinder 402, and a piercing pressing pair 403. The piercing pressing pair 403 includes an upper pressing member 4031 and a lower pressing member 4032 arranged opposite to each other. The first upper pressing cylinder 401 and the upper pressing member 4031 are disposed above the rubber-coated material belt 100, and the first lower pressing cylinder 402 and the lower pressing member 4032 are disposed below the rubber-coated material belt 100. The upper pressing member 4031 is drivenly connected to the first upper pressing cylinder 401, and the lower pressing member 4032 is drivenly connected to the first lower pressing cylinder 402. The upper pressing member 4031 or the lower pressing member 4032 is provided with a piercing tip 4033.

[0051] exist Figure 11 In section a, it shows the closed state of the puncture pressure pair 403. Figure 11 In b, it shows the state of the puncture pressure pair 403 before the puncture begins to close.

[0052] In this embodiment, the first upper cylinder 401 and the first lower cylinder 402 are telescopic cylinders, and their respective telescopic ends are connected to the upper pressure member 4031 or the lower pressure member 4032.

[0053] In order to make the upper tape 110 and the lower tape 120 adhere to each other and bond together Figure 11 As shown, in this embodiment, the piercing mechanism 4 is further provided with a first pressure roller pair 404 and a first pressure roller pair 404. The first pressure roller pair 404 and the first pressure roller pair 404 are respectively disposed on both sides of the piercing pressure pair 403. The first pressure roller pair 404 and the first pressure roller pair 404 respectively roll and press the rubber-coated strip 100.

[0054] Specifically, the first pressure roller pair 404 and the second pressure roller pair 405 are each composed of opposing rolling pressure rollers. The first pressure roller pair 404 is positioned at the front end of the perforated pressure pair 403, and the second pressure roller pair 405 is positioned at the rear end of the perforated pressure pair 403. When the upper adhesive tape 110 and the lower adhesive tape 120 pass through the first pressure roller pair 404, they are pressed and bonded together. When the upper adhesive tape 110 and the lower adhesive tape 120 pass through the second pressure roller pair 405, due to the perforation process, the second pressure roller pair 405 can further bond the upper adhesive tape 110 and the lower adhesive tape 120 together and expel some air from the center hole 130, positioning hole, and 140 of the washer part 200.

[0055] The rubber-coated strip 100 that passes through the piercing mechanism 4 will be laminated by the laminating mechanism 5.

[0056] Combination Figure 1 and Figure 12 As shown, in this embodiment, the film pressing mechanism 5 includes a second upper pressing cylinder 501, a second lower pressing cylinder 502, and a film pressing pair 503. The film pressing pair 503 includes an upper film pressing member 5031 and a lower film pressing member 5032 arranged opposite to each other. The second upper pressing cylinder 501 and the upper film pressing member 5031 are disposed above the adhesive strip 100, and the second lower pressing cylinder 502 and the lower film pressing member 5032 are disposed below the adhesive strip 100. The upper film pressing member 5031 is drivenly connected to the second upper pressing cylinder 501, and the lower film pressing member 5032 is drivenly connected to the second lower pressing cylinder 502.

[0057] In this embodiment, the second upper cylinder 501 and the second lower cylinder 502 are telescopic cylinders, and their respective telescopic ends are connected to the upper pressure diaphragm 5031 or the lower pressure diaphragm 5032.

[0058] Combination Figure 3 As shown, in order to detect whether the position of the rubber-coating strip 100 is accurate, so that the actions of each process are executed accurately, in this application, the gasket rubber-coating bonding device is also equipped with a vision inspection mechanism 6, which is set on the machine base 300.

[0059] Combination Figure 8 As shown, in this embodiment, the visual inspection mechanism 6 includes a light source emitter 601 for emitting inspection light 6011, an auxiliary positioning plate 602 for assisting positioning, and an imager 603 for receiving inspection projections and forming inspection image data.

[0060] The light source emitter 601 is located above the rubber-coated strip 100, the auxiliary positioning plate 602 is located between the light source emitter 601 and the rubber-coated strip 100, and the imager 603 is located below the rubber-coated strip 100. The auxiliary positioning plate 602 is hollowed out and has a positioning reticle 6021. The detection light 6011 illuminates the positioning reticle 6021 and the washer 200 of the rubber-coated strip 100 and projects it onto the imager 603.

[0061] Combination Figure 15 As shown, when the detection light 6011 projects the positioning collimator 6021 and the washer 200 onto the imager 603, the projected image is displayed on the monitor through the circuit, showing the image as shown.
