Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, and more specifically, to a 3M adhesive application equipment for door trim strips. Background Technology

[0002] In the furniture manufacturing industry, door trim strips are a common decorative and functional component, widely used on the surfaces of cabinet doors, etc. They can protect the edges of cabinet doors, reduce the noise of closing the door, and reduce wear and tear, while also beautifying the appearance of the cabinet doors. These trim strips usually need to be fixed with tapes with high adhesive strength. Among them, 3M double-sided tape has become one of the mainstream adhesive materials in this application due to its excellent initial tack, durability and environmental adaptability.

[0003] Currently, most companies still require manual application of 3M adhesive strips during production. The process typically involves operators cutting the tape roll, peeling off the release paper, aligning it according to the strip shape, and applying pressure to achieve initial bonding. During this process, it is difficult to control the force and uniformity of manual pressure, resulting in unevenness, edge lifting, air bubbles, and poor adhesion to the substrate. These quality issues not only lead to poor product appearance and reduced sealing performance, but also significantly reduce work efficiency due to rework and repairs. They also increase material waste and labor costs, seriously affecting overall production efficiency and product quality consistency.

[0004] Therefore, there is an urgent need for a 3M adhesive application device that can apply pressure evenly and position precisely to solve the above problems. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a 3M adhesive application device for door trim strips, thereby solving the technical problem of poor quality in the traditional manual application of 3M adhesive strips in the existing production process.

[0006] The purpose and effect of this utility model's 3M adhesive application device for door trim strips are achieved through the following specific technical means:

[0007] A 3M adhesive applicator for door trim strips includes a bracket, a base plate, and a housing. The base plate is connected to the top of the bracket by screws, and the housing is detachably connected to the top of the base plate. A cylinder is provided on the top of the housing.

[0008] The base plate is connected to a mounting base by screws. A lower mold is mounted on the top of the mounting base. Multiple air nozzles are mounted on the top of the lower mold. Multiple pressure sensors are installed inside the lower mold. 3M adhesive and an upper mold are installed on the top of the lower mold. Multiple suction cups are installed at the bottom of the upper mold.

[0009] The inner wall of the outer casing is detachably connected to a solenoid valve and a pressure reducing valve.

[0010] According to a preferred embodiment, the telescopic end of the cylinder is provided with a connecting block, the bottom of the connecting block is connected to the upper mold by screws, the top of the upper mold has multiple sets of first connecting holes, the tops of multiple sets of suction cups are all connected to the first connecting holes, and the bottom of the upper mold is fixedly connected with multiple sets of guide rods.

[0011] According to a preferred embodiment, the top of the bottom mold has multiple sets of guide holes, and multiple sets of guide rods are respectively inserted into the multiple sets of guide holes. The side of the lower mold has multiple sets of second connecting holes, and the bottom of the multiple sets of air nozzles are all connected to the second connecting holes.

[0012] According to a preferred embodiment, the top of the lower mold has multiple sets of mounting slots, and the pressure sensor is installed in each of the multiple sets of mounting slots.

[0013] According to a preferred embodiment, two sets of support plates are detachably connected inside the outer shell. The bottom of both sets of support plates is connected to the base plate. A slide rail is installed on one side of each set of support plates. A slider is locked on one side of each set of slide rails. One side of each set of sliders is connected to the upper mold by screws.

[0014] According to a preferred embodiment, one end of the solenoid valve is connected to a first connecting pipe, the other end of the first connecting pipe is connected to the pressure regulating valve, and two sets of second connecting pipes are connected to one side of the solenoid valve.

[0015] According to a preferred embodiment, the top of the housing has multiple sets of through holes, and two sets of the second connecting pipes pass through the through holes and are connected to the cylinder.

[0016] According to a preferred embodiment, the bottom of the bracket is provided with four sets of casters.

[0017] Based on the above aspects, this utility model has the following beneficial effects:

[0018] First, the upper and lower molds are connected to an external negative pressure device through the first and second connecting holes, respectively, creating negative pressure at the suction cup and air nozzle. The upper mold adsorbs the door trim, and the lower mold adsorbs 3M adhesive. After the protective film of the 3M adhesive is manually removed, the extension and retraction of the cylinder is controlled by a solenoid valve, and the pressure reducing valve adjusts the thrust of the cylinder. The cylinder drives the upper mold to slowly press down. Two sets of sliders and slide rails on one side of the upper mold guide the movement of the upper mold to prevent deviation. The guide rod at the bottom of the upper mold also prevents deviation between the upper and lower molds. After the upper and lower molds are closed, the cylinder maintains pressure, ensuring that the 3M adhesive and the door trim are fully bonded. Second, when the cylinder pushes the upper mold, the pressure sensor in the lower mold continuously provides feedback on the pressure on the lower mold. The controller controls the pressure reducing valve to control the thrust of the cylinder, preventing excessive local pressure on the door trim and 3M adhesive from causing uneven bonding and ensuring the uniformity of the bonding between the 3M adhesive and the door trim. This equipment can process continuously, improving processing efficiency and reducing human intervention (such as manual pressing), thus reducing quality fluctuations caused by individual operational differences.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] A 3M adhesive applicator for door trim includes a bracket 100, a base plate 101, and a housing 102. The base plate 101 is connected to the top of the bracket 100 by screws, and the housing 102 is detachably connected to the top of the base plate 101. A cylinder 103 is installed on the top of the housing 102. It is understood that the bracket 100 and the base plate 101 provide support for the overall equipment and ensure the stability of the equipment during use. Various necessary components can be installed inside the housing 102.

[0029] The top of the base plate 101 is connected to the mounting base 104 by screws. The mounting base 104 is equipped with a lower mold 105. The mounting base 104 is equipped with a lower mold 105 to prevent the lower mold 105 from slipping, which would cause deviations in the mold closing process and result in product defects. The top of the lower mold 105 is equipped with multiple sets of air nozzles 106, which can adsorb 3M adhesive 109. The lower mold 105 is equipped with multiple sets of pressure sensors 108, which can be DJDD-130M model. The top of the lower mold 105 is equipped with 3M adhesive 109 and an upper mold 107. The bottom of the upper mold 107 is equipped with multiple sets of suction cups 110, which can pick up the door trim strip. When the upper mold 107 and the lower mold 105 are closed, the 3M adhesive 109 can be attached to the surface of the door trim strip.

[0030] The inner wall of the outer casing 102 is detachably connected to a solenoid valve 111 and a pressure reducing valve 112. Both the solenoid valve 111 and the pressure reducing valve 112 can be connected to an external control module (not shown in the figure). The solenoid valve 111 can control the extension and retraction of the cylinder 103, and the pressure reducing valve 112 can control the thrust of the cylinder 103, making the control of the cylinder 103 more precise.

[0031] The telescopic end of the cylinder 103 is provided with a connecting block 113. The bottom of the connecting block 113 is connected to the upper mold 107 by screws. The connection block 113 allows the cylinder 103 to be connected to the upper mold 107. When the telescopic end of the cylinder 103 moves, it can drive the upper mold 107 to move. The top of the upper mold 107 is provided with multiple sets of first connecting holes 114. The tops of multiple sets of suction cups 110 are all connected to the first connecting holes 114. The multiple sets of first connecting holes 114 can be connected to an external negative pressure device (not shown in the figure). The external negative pressure device can generate negative pressure at the ports of multiple sets of suction cups 110, thereby adsorbing the door trim strip, which is convenient for subsequent mold closing and 3M adhesive 109 attachment. The bottom of the upper mold 107 is fixedly connected with multiple sets of guide rods 115.

[0032] The lower mold 105 has multiple sets of guide holes on its top, and multiple sets of guide rods 115 are respectively inserted into the multiple sets of guide holes. The setting of guide rods 115 and guide holes can make the mold closing process of the upper mold 107 and the lower mold 105 more accurate, and prevent the product defects caused by the mold closing deviation. Multiple sets of second connecting holes 116 are provided on one side of the lower mold 105. The bottom of multiple sets of air nozzles 106 are all connected to the second connecting holes 116. The second connecting holes 116 can be connected to an external negative pressure device, so that negative pressure is generated at the multiple sets of air nozzles 106, thereby adsorbing the 3M adhesive 109.

[0033] The top of the lower mold 105 has multiple sets of mounting slots, and each set of mounting slots is equipped with a pressure sensor 108. The pressure sensor 108 is electrically connected to an external control module. The pressure sensor 108 can provide feedback on the pressure on the lower mold 105 after the upper mold 107 and the lower mold 105 are closed, so that the user can adjust the thrust of the cylinder 103 according to the pressure to prevent the door trim strip from not adhering properly to the 3M adhesive 109 or from being under too much pressure.

[0034] Two sets of support plates 117 are detachably connected inside the outer casing 102. The support plates 117 can provide certain support for the top of the outer casing 102 to prevent the cylinder 103 installed on the top of the outer casing 102 from shaking. The bottom of both sets of support plates 117 is connected to the base plate 101. A slide rail 118 is installed on one side of each set of support plates 117. A slider 119 is locked on one side of each set of slide rails 118. One side of each set of sliders 119 is connected to the upper mold 107 by screws. It can be understood that when the cylinder 103 drives the upper mold 107 to move up and down, the cooperation between the slider 119 and the slide rail 118 can provide a guiding effect for the movement of the upper mold 107, preventing the upper mold 107 from deviating during the movement, thereby causing mold closing deviation.

[0035] One end of the solenoid valve 111 is connected to a first connecting pipe 120, and the other end of the first connecting pipe 120 is connected to a pressure reducing valve 112. Two sets of second connecting pipes 121 are connected to one side of the solenoid valve 111.

[0036] Multiple sets of through holes are provided on the top of the outer casing 102, and two sets of second connecting pipes 121 pass through the through holes and are connected to the cylinder 103.

[0037] The bottom of the bracket 100 is equipped with four sets of casters 122, which facilitate the movement of the equipment and improve its flexibility.

[0038] The specific usage and function of this embodiment are as follows:

[0039] First, the user activates the external negative pressure device. The 3M adhesive 109 and door trim strip are manually applied to the lower mold 105 and upper mold 107 respectively, ensuring the product perfectly aligns with the mold positioning reference. Then, the protective film on the 3M adhesive 109 is peeled off, ensuring the bonding surface is clean and uncontaminated. The solenoid valve 111 controls the cylinder 103 to extend downwards, moving the upper mold 107 downwards to close with the lower mold 105, allowing the 3M adhesive 109 to adhere to the door trim strip. The pressure sensor 108 monitors the closing pressure in real time, ensuring the 3M adhesive 109 is evenly pressurized. The pressure relief valve 112 adjusts the thrust of the cylinder 103 to maintain the closing pressure at 0.3-0.6 MPa for 5-10 minutes. Then, the control module controls the solenoid valve 111 to reset the cylinder 103, shutting off the negative pressure device, and the user manually removes the product using anti-static tools.
