[0040] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0041] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0042] Please refer to Figures 1-5 This embodiment provides an adhesive applicator 100, which includes an adhesive applicator table 110, a first positioning unit 120, a second positioning unit 130, and a pressing component 140.

[0043] The first positioning unit 120 is connected to the adhesive application table 110 and is used to position the sealing gasket 10 to be pressed; the second positioning unit 130 is connected to the adhesive application table 110 and is used to position the workpiece 20 to be pressed directly above the sealing gasket 10 to be pressed.

[0044] The pressing assembly 140 is connected to the adhesive application table 110 and is used to apply external force to the workpiece 20 to be pressed, so that it moves toward the sealing gasket 10 to be pressed, thereby pressing the sealing gasket 10 and the workpiece 20 to be pressed together.

[0045] Please refer to Figures 1-5 The working principle of the adhesive applicator 100 is as follows:

[0046] First, the adhesive applicator 100 is used to attach the sealing gasket 10 to the surface of the workpiece 20. In this embodiment, the workpiece 20 is a panel product, while in other embodiments, the workpiece 20 may be a long strip or other irregularly shaped product. In this embodiment, the work of attaching the sealing gasket 10 to the corresponding surface of the workpiece 20 is called adhesive applicator.

[0047] The adhesive applicator 100 includes an adhesive applicator 110, a first positioning unit 120, a second positioning unit 130, and a pressing assembly 140.

[0048] With the above-described structure, during the process of applying adhesive to the workpiece 20, the first positioning unit 120 and the second positioning unit 130 respectively position the sealing gasket 10 and the workpiece 20, thereby ensuring that the two maintain the correct relative position in the device. Then, the two can be pressed together by the pressing component 140 to complete the adhesive application process.

[0049] This setup improves the quality and efficiency of adhesive application by simultaneously positioning the sealing gasket 10 and the workpiece 20, increases the flatness of the sealing gasket 10, and reduces its rework and scrap rates, thereby lowering the overall cost of adhesive application. Furthermore, during the adhesive application process, this embodiment uses a preset direction so that the positioned sealing gasket 10 is located below the positioned workpiece 20, with the pressing component 140 acting on the upper side of the workpiece 20. The preset direction in this embodiment can be a vertical direction.

[0050] Further, please refer to Figures 1-8In this embodiment, when configuring the adhesive application table 110, the adhesive application table 110 includes a base plate 111, a placement table 112, and multiple supports 113. The placement table 112 is connected to the base plate 111 via multiple supports 113 and is spaced apart from the base plate 111. A pressing area 114 is provided on the side of the placement table 112 facing away from the base plate 111. This configuration allows for improved positioning accuracy by configuring a pressing area 114 on the placement table 112 that matches the shape and contour of the sealing gasket 10. Furthermore, when adjusting the pressed workpiece 20, the adhesive application requirements of different types of workpieces 20 can be accommodated by replacing the corresponding placement table 112.

[0051] When configuring the first positioning unit 120, this embodiment uses a first positioning unit 120 including a plurality of elastic positioning elements 121. The plurality of elastic positioning elements 121 are arranged around the contour of the pressing area 114, and the plurality of elastic positioning elements 121 are movably connected to the placement table 112 along a preset direction.

[0052] Each elastic positioning element 121 protrudes partially from the pressing area 114 under elastic action, and its protruding part is used to cooperate with the positioning hole 11 of the sealing gasket 10 to be pressed, and to abut against the workpiece 20 to be pressed directly above the sealing gasket 10.

[0053] With this configuration, the portion of the elastic positioning member 121 protruding from the pressing area 114 can position the sealing gasket 10 to be pressed, and it can also abut against the positioned workpiece 20, thus working together with the second positioning unit 130 to position the workpiece 20. Then, under the action of the pressing assembly 140, when the workpiece 20 moves toward the sealing gasket 10, the sealing gasket 10 can be made to adhere to the surface of the workpiece 20. At this time, as the workpiece 20 moves, the elastic positioning member 121 can also retract against its elastic force. After the pressing is completed, that is, after the external force of the pressing assembly 140 on the workpiece 20 disappears, the elastic positioning member 121 can also make the workpiece 20 pop out under its elastic force, so as to remove the pressed workpiece 20.

[0054] Based on the above structure, in order to enable the elastic positioning member 121 to move relative to the placement stage 112, the placement stage 112 is provided with a plurality of movable holes 115, and each elastic positioning member 121 is matched with one movable hole 115.

[0055] The elastic positioning element 121 includes a movable sleeve 122, an elastic element 123, and a guide post 124;

[0056] The guide post 124 is connected to the base plate 111 and extends in a preset direction toward its corresponding movable hole 115. The elastic element 123 is sleeved on the guide post 124, and part of the movable sleeve 122 is sleeved on the guide post 124 and abuts against the elastic element 123.

[0057] The elastic element 123 is used to make the movable sleeve 122 have a tendency to move in a predetermined direction in a direction that protrudes from the pressing area 114.

[0058] Thus, with this arrangement, the movable sleeve 122 can move relative to the guide post 124 under the action of the elastic member 123 and extend into the corresponding movable hole 115 towards the workpiece 20, thereby positioning and engaging with the positioning hole 11 of the sealing gasket 10 located in the pressing area 114. Furthermore, after protruding from the positioning hole 11, it can abut against the workpiece 20 located above the sealing gasket 10. In this way, under the action of the pressing assembly 140, when the workpiece 20 moves towards the sealing gasket 10, the movable sleeve 122 can overcome the elastic force of the elastic member 123 and retract from the movable hole 115. Then, after pressing is completed, that is, after the external force of the pressing assembly 140 on the workpiece 20 disappears, the movable sleeve 122 can also cause the workpiece 20 to pop out under the action of the elastic member 123, facilitating the removal of the pressed workpiece 20. In this embodiment, the elastic member 123 can be a spring sleeved on the guide post 124.

[0059] Further, please refer to Figures 1-8 In this embodiment, when configuring the second positioning unit 130, the second positioning unit 130 includes a plurality of positioning elements 131, which are distributed around the pressing area 114. The plurality of positioning elements 131 are used to guide the workpiece 20 to be pressed 20 to be pressed and to be pressed into contact with the sealing gasket 10 when the workpiece 20 moves toward the sealing gasket 10 to be pressed. With this arrangement, the workpiece 20 can be positioned. Moreover, based on the above, in addition to the positioning of the workpiece 20 by the plurality of positioning elements 131, the workpiece 20 can also be positioned by the aforementioned movable sleeve 122. The purpose is to improve the adhesive application quality and ensure the flatness of the sealing gasket 10.

[0060] Furthermore, in order to improve the positioning efficiency of the workpiece 20, when configuring multiple positioning elements 131, the positioning elements 131 on the two adjacent sides of the pressing area 114 are positioning posts 132, and the positioning elements 131 on the other two adjacent sides are alignment blocks 133; wherein, along the preset direction, the height of the positioning posts 132 is higher than that of the alignment blocks 133.

[0061] Thus, with this arrangement, positioning posts 132 and alignment blocks 133 are arranged around the workpiece 20. Since the positioning posts 132 are higher than the alignment blocks 133, the purpose is to quickly place the workpiece 20 into the second positioning unit 130 by moving it towards the position where it contacts the positioning posts 132. Then, guided by the positioning posts 132 and alignment blocks 133, the workpiece 20 moves towards the sealing gasket 10, and during this process, it is positioned and aligned until it abuts against the lower movable sleeve 122. To ensure that the alignment blocks 133 can effectively position and guide the workpiece 20, each alignment block 133 has a guide ramp 134 or a guide arc surface on the side facing the pressing area 114.

[0062] Based on the above structure, please refer to Figures 1-9 In this embodiment, when the pressing assembly 140 is configured, the pressing assembly 140 includes a pressing frame 141, a pressing plate 142, and a driving member 143; wherein, in this embodiment, the driving member 143 is a cylinder.

[0063] The holding frame 141 is connected to the adhesive application table 110, the driving member 143 is connected to the holding frame 141, and the pressure plate 142 is connected to the movable end of the driving member 143. The pressure plate 142 is used to hold the workpiece 20 to be pressed under the driving action of the driving member 143, and to make the workpiece 20 to be pressed move toward the sealing gasket 10 to be pressed.

[0064] Thus, with the above-described structure, the pressure plate 142 can be driven by the drive member 143 to move relative to the holding plate, thereby causing the pressure plate 142 located above the workpiece 20 to move toward the workpiece 20. After contacting the workpiece 20, the pressing work can be completed as it continues to move in the same direction.

[0065] During the movement of the pressure plate 142, in order to ensure that the force at each contact point is the same after it comes into contact with the workpiece 20, that is, to improve the uniformity of the force on the workpiece 20, the pressing assembly 140 also includes a guide post 144 extending in a preset direction. The guide post 144 is connected to the pressure plate 142, and the pressing frame 141 is provided with a guide hole 145 that slides with the guide post 144. Moreover, in order to avoid impact between the pressure plate 142 and the workpiece 20, a flexible pad 146 is provided on the side of the pressure plate 142 that is in contact with the workpiece 20 to be pressed. For example, the flexible pad 146 can be set as a sponge pad, the purpose of which is to play a contact buffering role.

[0066] Based on the above, please refer to Figures 1-9 The working steps of the adhesive applicator 100 are as follows:

[0067] Before applying the adhesive, the operator tears off the adhesive paper of the sealing gasket 10 and places it in the pressing area 114 with the sticky side facing up. When placing the sealing gasket 10, the multiple movable sleeves 122 protruding from the pressing area 114 are matched one-to-one with the multiple positioning holes 11 on the sealing gasket 10. In this embodiment, 18 elastic positioning elements 121 are configured, and the sealing gasket 10 is provided with 18 corresponding positioning holes 11.

[0068] Then, after aligning the workpiece 20 with the three positioning posts 132, it is released onto the alignment block 133, allowing it to slide freely and slowly off the alignment block 133. This achieves alignment and positioning. During this process, since the alignment block 133 has a large flat chamfer (i.e., a guide slope 134 or a guide arc surface), when the product is not placed correctly, it will contact the slope and then slide to the correct position. The workpiece 20 abuts against the movable sleeve 122. At this time, there is a distance between the workpiece 20 and the sealing gasket 10, preventing the product from contacting the sealing gasket 10 before applying the adhesive.

[0069] Once all preparations are complete, the operator activates the switch with both hands. Upon activation, the pressure plate 142 begins to move downwards, contacting the surface of the workpiece 20 and pressing it downwards. At this time, the movable sleeve 122 is under pressure, the spring is compressed, and the movable sleeve 122 moves downwards along the guide post 124, bringing the workpiece 20 into contact with the sealing gasket 10, thus achieving semi-automatic adhesive application to the workpiece 20. It should be noted that the operator should be required to use both hands when activating the switch to prevent injury from single-handed operation.

[0070] After the adhesive is applied, the cylinder holds pressure for 5 seconds before pulling the pressure plate 142 back to its original position to ensure that the sealing gasket 10 and the workpiece 20 are tightly fitted and fully adhesive is applied. In addition, a sponge pad is attached to the product side of the pressure plate 142 to prevent the pressure plate 142 from damaging the product.

[0071] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
