Description

Technical Field

[0001] This application relates to the field of rubber processing and assembly technology, and more specifically, to a rubber bonding device. Background Technology

[0002] In the design of power hand tools such as drills, angle grinders, and edge trimmers, grip rubber is typically fitted to the holding area of ​​the casing to enhance operational safety and comfort. This grip rubber has a dual core function: firstly, it increases the friction between the operator's hand and the tool casing through surface texture or material properties, effectively preventing the tool from slipping due to vibration, oil, or other factors during use, thus ensuring operational safety; secondly, it absorbs vibrations generated during tool operation using its own elastic deformation properties, reducing the transmission of vibrations to the hand, lowering fatigue from prolonged use, and significantly improving hand comfort.

[0003] The assembly and bonding of the outer shell and the grip rubber is a critical process in the production of power hand tools. The quality of this bonding directly determines the user experience, structural stability, and appearance of the product. If the bonding position is off, it will not only affect the grip feel and anti-slip and shock absorption effects, but also lead to appearance defects. If the rubber is not tightly bonded to the outer shell, it is prone to peeling and falling off during use, seriously affecting the product's lifespan and market reputation.

[0004] Currently, the industry generally uses manual pasting for this assembly process. The specific operation procedure is as follows: First, the operator manually peels off the release paper (adhesive backing) from the back of the rubber sheet, exposing the adhesive side. Second, based on visual observation and experience, the operator aligns the rubber sheet with the pre-set pasting area (pasting frame) on the outer shell to complete the initial pasting. Third, the operator visually checks whether the rubber sheet is completely within the pasting frame. If there are any issues such as misalignment or exceeding the boundary, the rubber sheet must be peeled off the outer shell, and the alignment and pasting steps must be repeated. Fourth, once the rubber sheet is pasted in the correct position, the operator uses a cloth or other tools to press and wipe the surface of the rubber sheet, applying pressure manually to ensure that the rubber sheet adheres fully to the outer shell surface, eliminating air between the contact surfaces, and ensuring a firm bond.

[0005] However, the aforementioned manual pasting method has several inherent drawbacks: First, the positioning accuracy relies on the operator's visual judgment and operational experience, which is highly subjective and makes it difficult to guarantee the consistency of pasting positions in mass production, easily leading to deviations; second, the uneven pressure distribution during manual pressing and wiping results in unstable adhesion between the rubber and the outer shell, and some areas may have residual air bubbles due to insufficient pressing, creating a risk of detachment; third, the rework rate is high, which not only reduces production efficiency, but repeated peeling of the rubber may also damage its adhesive surface or the outer shell surface, further affecting product quality and the needs of mass production; fourth, because it relies on manual visual alignment and manual operation, operators need to have a high level of operational proficiency and accuracy, and new employees need to undergo a long period of training and practice before they can reach a qualified operating level, increasing the company's human resource training costs and time costs. Utility Model Content

[0006] In view of this, this application provides a rubber bonding device, which aims to improve the problems of low rubber positioning accuracy, bonding quality, low production efficiency, and high labor costs in the prior art.

[0007] This application provides a rubber adhesive device, comprising:

[0008] frame;

[0009] The housing positioning mechanism is used to position and fix the housing.

[0010] A rubber positioning mechanism is used to position and fix the rubber, wherein the adhesive side of the rubber faces outward;

[0011] A first driving component is connected to the housing positioning mechanism and is used to drive the housing positioning mechanism to reciprocate along a first direction.

[0012] A pressing mechanism includes two pressing frames, a roller support, a compaction seat disposed between the two pressing frames, and a pair of roller shafts. Each roller shaft is connected to one pressing frame via the roller support. One side of the roller support is rotatably connected to the pressing frame, and the other side of the roller support is rotatably connected to the roller shaft. In a first direction, the roller shaft is located between the housing positioning mechanism and the compaction seat. The compaction seat has a compaction groove on the side near the roller shaft, and the compaction groove is adapted to the outer peripheral surface of the housing. The pressing mechanism and the rubber positioning mechanism are arranged along a second direction and are both slidably connected to the frame along the second direction. The second direction is perpendicular to the first direction. In the second direction, the housing positioning mechanism is located on the same side, opposite side, or aligned with the pressing mechanism or the rubber positioning mechanism in the first direction.

[0013] The second driving component is used to synchronously or separately drive the rubber positioning mechanism and the pressing mechanism to reciprocate along the second direction.

[0014] Preferably, the rubber positioning mechanism includes a positioning base body, a negative pressure generator, and a plurality of adsorption holes. The plurality of adsorption holes are installed on the positioning base body, and the negative pressure generator is connected to the adsorption holes to generate negative pressure in the adsorption holes. The adsorption holes are used to adsorb and fix the non-adhesive surface of the rubber.

[0015] Preferably, the positioning seat body is provided with a positioning groove for accommodating the rubber, and the groove wall is used to abut against the outer contour of the rubber.

[0016] Preferably, the rubber positioning mechanism and the pressing mechanism are both mounted on the assembly base, and the assembly base is slidably connected to the frame through a sliding mechanism; the second driving component is connected to the assembly base.

[0017] Preferably, the sliding mechanism includes a slide rail and a sliding seat, the slide rail extends along the second direction and is fixedly connected to the frame, the sliding seat is slidably connected to the slide rail, and the mounting base is installed on the sliding seat.

[0018] Preferably, the housing positioning mechanism is slidably connected to the frame via a guide mechanism.

[0019] Preferably, the guiding mechanism includes a guide rail and a guide seat, the guide rail extends along the second direction and is fixedly installed on the frame, the guide seat is slidably connected to the guide rail, and the housing positioning mechanism is installed on the guide seat.

[0020] Preferably, the outer shell is a circular sleeve structure; the outer shell positioning mechanism includes a mounting post, which is used to fit the inner diameter hole of the outer shell.

[0021] Compared with the prior art, the adhesive bonding device provided in this application achieves at least the following beneficial effects:

[0022] In the rubber pasting device provided in this application, the housing positioning mechanism and the rubber positioning mechanism respectively realize the positioning and fixing of the housing and the rubber, and the adhesive side of the rubber faces outward, so it can be directly aligned with the area to be pasted, avoiding adhesive contamination or positional displacement during the positioning process; it ensures the relative positional accuracy of the housing and the rubber before pasting from the source, and provides a stable benchmark for subsequent accurate pasting.

[0023] In the pressing mechanism, the roller shaft is rotatably connected to the pressing frame via a roller support. This allows for rolling pressing of the contact area between the rubber and the outer shell during the initial bonding stage. Rolling friction replaces sliding friction, reducing rubber wrinkles and air bubbles, and simultaneously ensuring the adhesive adheres initially to the shell surface, laying the foundation for subsequent precision pressing. The compaction seat, near the roller shaft, has a compaction groove that matches the outer circumference of the shell, allowing for precise conformation to the shell's contour. This provides comprehensive and uniform surface contact compaction of the pre-pressed area, ensuring full adhesion between the adhesive and the shell surface and improving bonding strength. This progressive pressing method avoids problems such as insufficient localized pressing and uneven bonding strength that are common with single-press structures, significantly improving the overall quality and consistency of the rubber bonding.

[0024] The first driving component drives the housing positioning mechanism to reciprocate along a first direction, causing the housing to move closer to or further away from the pressing mechanism and the rubber positioning mechanism along a preset trajectory, thus achieving feeding and resetting during the pasting process. The second driving component synchronously or separately drives the rubber positioning mechanism and the pressing mechanism to move in a second direction, achieving precise alignment of the rubber and the housing in the second direction, and allowing adjustment of the pressing mechanism's position according to pasting requirements. The coordinated operation of the two-way driving mechanism eliminates the need for manual intervention in the entire pasting process, achieving automated continuous operation, significantly improving pasting efficiency, and avoiding random errors inherent in manual operation.

[0025] Of course, any product implementing this application need not specifically need to achieve all of the technical effects described above at the same time.

[0047] Please refer to Figures 1 to 8 This application provides a rubber bonding device, including a frame 100, a housing positioning mechanism 200, a rubber positioning mechanism 300, a first driving member 400, a pressing mechanism 500, and a second driving member 600.

[0048] The outer casing positioning mechanism 200 is used to position and fix the outer casing 10.

[0049] The rubber positioning mechanism 300 is used to position and fix the rubber 20, with the adhesive side of the rubber 20 facing outwards;

[0050] The first driving component 400 is connected to the housing positioning mechanism 200 and is used to drive the housing positioning mechanism 200 to reciprocate along the first direction D1.

[0051] The pressing mechanism 500 includes two pressing frames 520, a compaction seat 530 disposed between the two pressing frames 520, and a pair of roller shafts 510. Each roller shaft 510 is connected to one pressing frame 520 via a roller support 540. One side of the roller support 540 is rotatably connected to the pressing frame 520, and the other side is rotatably connected to the roller shaft 510. In the first direction D1, the roller shaft 510 is located between the housing positioning mechanism 200 and the compaction seat 530. The compaction seat 530 is close to the roller shaft. A compaction groove 531 is provided on one side of the axle 510, and the compaction groove 531 is adapted to the outer peripheral surface of the housing 10; the pressing mechanism 500 and the rubber positioning mechanism 300 are arranged along the second direction D2 and are both slidably connected to the frame 100 along the second direction D2. The second direction D2 is perpendicular to the first direction D1. On the second direction D2, the housing positioning mechanism 200 is located on the same side or opposite side of the pressing mechanism 500 and the rubber positioning mechanism 300 in the first direction D1, or aligned with the pressing mechanism 500 or the rubber positioning mechanism 300.

[0052] The second driving component 600 is used to synchronously or separately drive the rubber positioning mechanism 300 and the pressing mechanism 500 to reciprocate along the second direction D2.

[0053] In specific implementation, the first driving component 400 and the second driving component 600 can be any one or more combinations of pneumatic, hydraulic, or electric power sources. This embodiment does not impose specific limitations on this, as long as the first driving component 400 can drive the housing positioning mechanism 200 to reciprocate along the first direction D1, and the second driving component 600 can drive the rubber positioning mechanism 300 and the pressing mechanism 500 to reciprocate along the second direction D2. In practical applications, the specific structure and power source type of the driving component can be determined comprehensively based on factors such as the equipment usage scenario, power requirements, control accuracy requirements, and cost budget. This embodiment does not limit the specific structure of the driving component or the type of power source.

[0054] It should be understood that, in the second direction D2, the housing positioning mechanism 200 can be located on the same side or opposite side of the pressing mechanism 500 and the rubber positioning mechanism 300 in the first direction D1, or aligned with the pressing mechanism 500 or the rubber positioning mechanism 300. This flexible layout design allows the device to adapt to the rubber 20 pasting requirements of housings 10 of different sizes and shapes. When dealing with small housings 10 or short-distance pasting scenarios, a same-side layout can be used to shorten the movement stroke; when dealing with large housings 10 or complex contour pasting scenarios, an opposite-side layout can be used to expand the operating space; when high-precision alignment and pasting of the housing and rubber are required, a layout in which the housing positioning mechanism is aligned with the pressing mechanism or the rubber positioning mechanism can be used to further improve the accuracy of the pasting position. This setting enhances the versatility and applicability of the device and reduces the equipment replacement cost for pasting operations of products of different specifications.

[0055] In one specific implementation of this embodiment, see [link to relevant documentation]. Figure 1 In the second direction D2, the outer shell positioning mechanism 200 and the rubber positioning mechanism 300 are aligned. The following uses the rubber pasting device as an example to illustrate the working process of the profile cutting device provided in this embodiment:

[0056] (Workpiece positioning stage) The operator first installs the outer casing 10 onto the outer casing positioning mechanism 200, such as... Figure 2 As shown. The outer shell positioning mechanism 200 positions and fixes the outer shell 10 to ensure that the outer shell 10 will not shift or shake during the subsequent pasting process; at the same time, the rubber sheet 20 is installed on the rubber sheet positioning mechanism 300, and the release paper (adhesive backing paper) on the back of the rubber sheet is peeled off, so that the adhesive backing of the rubber sheet 20 faces outward (towards the direction of subsequent contact with the outer shell 10), and the rubber sheet positioning mechanism 300 completes the positioning and fixing of the rubber sheet 20.

[0057] (Position Adjustment Stage 1) Since the rubber positioning mechanism 300 is initially aligned with the outer shell positioning mechanism 200 (collinear in the first direction) in this embodiment, this step can be directly omitted.

[0058] However, in embodiments where the outer shell positioning mechanism 200 is located on the same side or opposite side of the pressing mechanism 500 and the rubber positioning mechanism 300 in the first direction D1, respectively, this step needs to be performed: according to the bonding position requirements of the outer shell 10 and the rubber 20, the second driving member 600 is activated and drives the rubber positioning mechanism 300 to move along the second direction D2 (perpendicular to the first direction D1). Figure 3 The rubber positioning mechanism 300 is adjusted to be on the movement trajectory of the outer shell positioning mechanism 200 (i.e., the rubber positioning mechanism 300 and the outer shell positioning mechanism 200 are collinear in the first direction D1). At this time, the adhesive backing surface of the rubber 20 and the surface of the outer shell 10 to be pasted are in a preset alignment state, which prepares for subsequent preliminary pasting.

[0059] (In the initial bonding stage) The first driving component 400 is activated, which drives the shell positioning mechanism 200 connected to it to move closer to the rubber positioning mechanism 300 along the first direction D1. When the surface of the shell 10 to be bonded moves to contact the adhesive backing surface of the rubber 20, the adhesive backing is used to make the shell 10 and the rubber 20 initially bonded, forming an initial bonding structure. At this time, the rubber 20 has been initially attached to the shell 10, but has not yet been fully compacted.

[0060] (Second stage of position adjustment) After the initial pasting is completed, the first driving component 400 drives the housing positioning mechanism 200 to move along the first direction D1, so that the housing positioning mechanism 200 carrying the initially pasted housing 10 and rubber 20 reaches the preset transition position, such as... Figure 4 Simultaneously, the second driving component 600 drives the pressing mechanism 500 to move along the second direction D2 until the pressing mechanism 500 is adjusted to the movement trajectory of the housing positioning mechanism 200 (i.e., the pressing mechanism 500 and the housing positioning mechanism 200 are collinear in the first direction D1), ensuring that the subsequent rolling and compaction operation can be applied to the initially bonded structure, preparing for the subsequent initial pressing, such as... Figure 5 .

[0061] (Rolling and compaction stage) The first driving member 400 drives the outer shell positioning mechanism 200 to continue moving closer to the pressing mechanism 500 along the first direction D1. The pair of roller shafts 510 in the pressing mechanism 500 first contact the front (non-adhesive surface) of the initially pasted outer shell 10 and rubber 20 and perform a rolling and compaction operation on them. During this process, the first driving member 400 continuously applies driving force, causing the outer shell positioning mechanism 200 (carrying the initially pasted outer shell 10 and rubber 20) to apply stable pressure to the roller shafts 510, and the roller shafts 510 press the non-adhesive surface of the rubber 20 against the outer wall of the outer shell 10. Because one side of the roller support 540 is rotatably connected to the pressing frame 520 and the other side is rotatably connected to the roller shaft 510, under pressure, the roller shaft 510, together with the roller support 540, rotates around the rotational connection axis between the roller support 540 and the pressing frame 520; simultaneously, the frictional force generated between the rubber sheet 20 and the roller shaft 510 drives the roller shaft 510 to rotate itself. As the outer casing 10 continues to advance, the two roller shafts 510 gradually open towards the compaction seat 530, as... Figure 6 and Figure 7 As shown, the gap between the two roller shafts 510 gradually increases. While the roller shafts 510 rotate on their own axis, they revolve around the rotating connecting shaft to ensure that the rubber 20 can be fully and evenly applied along the outer circumference of the outer shell 10, thus completing the basic compaction and bonding.

[0062] (Contact Compaction Stage) When the gap between the two roller shafts 510 increases sufficiently to allow the basically bonded outer shell 10 and rubber 20 to pass through, the first drive member 400 continues to drive the outer shell positioning mechanism 200 forward, so that the outer shell 10 and rubber 20 are integrally embedded into the compaction groove 531 of the compaction seat 530 (the compaction groove 531 is adapted to the outer peripheral surface of the outer shell 10). Through the complete wrapping and bonding of the outer peripheral surface of the outer shell 10 by the compaction groove 531, air bubbles and gaps between the rubber 20 and the outer shell 10 are further eliminated, ensuring that the rubber 20 and the outer shell 10 are fully and tightly bonded, achieving the preset bonding effect.

[0063] After the contact compaction stage (reset and part removal stage) is completed, the first driving component 400 drives the outer shell positioning mechanism 200 to move in the opposite direction along the first direction D1 to the initial position for reset; simultaneously, the second driving component 600 drives the rubber positioning mechanism 300 and the pressing mechanism 500 to move in the opposite direction along the second direction D2 to their respective initial positions for reset, as shown below. Figure 8 As shown. After all mechanisms have reset, the operator removes the pasted product from the outer casing positioning mechanism 200, thus completing one full adhesive 20 pasting process.

[0064] In the rubber pasting device provided in this embodiment, the housing positioning mechanism 200 and the rubber pasting mechanism 300 respectively realize the positioning and fixing of the housing and the rubber pasting 20. The adhesive side of the rubber pasting 20 faces outward, so it can be directly aligned with the area to be pasted, avoiding adhesive contamination or positional displacement during the positioning process. This ensures the relative positional accuracy of the housing 10 and the rubber pasting 20 before pasting from the source, providing a stable benchmark for subsequent accurate pasting.

[0065] In the pressing mechanism 500, the roller shaft 510 is rotatably connected to the pressing frame 520 via the roller support 540. This allows for rolling pressing of the contact area between the rubber 20 and the outer shell 10 during the initial bonding stage. Rolling friction replaces sliding friction, reducing wrinkles and air bubbles in the rubber 20 and ensuring the adhesive adheres initially to the surface of the outer shell 10, laying the foundation for subsequent precision pressing. The compaction seat 530, near the roller shaft 510, has a compaction groove 531 adapted to the outer circumference of the outer shell. This groove precisely conforms to the contour of the outer shell 10, providing comprehensive and uniform surface contact compaction of the pre-pressed area. This ensures full adhesion between the adhesive and the surface of the outer shell 10, improving bonding strength. This progressive pressing method avoids problems such as insufficient local pressing of the rubber 20 and uneven bonding strength, significantly improving the overall quality and consistency of the rubber 20 bonding.

[0066] The first driving component 400 drives the outer shell positioning mechanism 200 to reciprocate along the first direction D1, which can cause the outer shell 10 to move closer to or further away from the pressing mechanism 500 and the rubber positioning mechanism 300 along a preset trajectory, realizing the feeding and resetting of the pasting process; the second driving component 600 synchronously or separately drives the rubber positioning mechanism 300 and the pressing mechanism 500 to move in the second direction D2, which can not only achieve precise alignment of the rubber 20 and the outer shell 10 in the second direction D2, but also adjust the position of the pressing mechanism 500 according to the pasting requirements. The coordinated operation of the two-way driving makes the entire pasting process without manual intervention, realizing automated continuous operation, greatly improving pasting efficiency, and avoiding random errors of manual operation.

[0067] Figure 9 The diagram shown is a structural schematic of the rubber positioning mechanism 300 provided in an embodiment of this application.

[0068] See Figure 1 and Figure 9 In some embodiments, the rubber positioning mechanism 300 includes a positioning seat 310, a negative pressure generator, and a plurality of adsorption holes 320. The plurality of adsorption holes 320 are installed on the positioning seat 310, and the negative pressure generator is connected to the adsorption holes 320 to generate negative pressure in the adsorption holes 320. The adsorption holes 320 are used to adsorb and fix the non-adhesive surface of the rubber 20.

[0069] In this embodiment, the adsorption holes 320 only adsorb the non-adhesive surface of the rubber sheet 20, avoiding contact contamination or mechanical damage to the adhesive backing surface; the multiple adsorption holes 320 are evenly distributed to form a planar adsorption, making the rubber sheet 20 flat and fixed; feeding only requires placing the rubber sheet 20 and starting the negative pressure, reducing the difficulty of operation, shortening the process preparation time, and indirectly improving production efficiency.

[0070] See Figure 1 and Figure 9 In some embodiments, the positioning seat 310 is provided with a positioning groove 311 for accommodating the rubber 20, and the groove wall of the positioning groove 311 is used to abut against the outer contour of the rubber 20.

[0071] In this embodiment, the groove wall of the positioning groove 311 can provide a precise positioning reference for the rubber 20, ensuring that the rubber 20 is in an accurate position during the pasting process, thereby improving the accuracy of pasting the rubber 20 to the outer shell 10 and reducing the possibility of pasting position deviation.

[0072] See Figures 1 to 6 In some embodiments, the rubber positioning mechanism 300 and the pressing mechanism 500 are both mounted on the assembly base 110. The assembly base 110 is slidably connected to the frame 100 through the sliding mechanism 120, and the second driving member 600 is connected to the assembly base 110.

[0073] In this embodiment, the rubber positioning mechanism 300 and the pressing mechanism 500 are integrated into the same mounting base 110. The second driving component 600 is linked with the mounting base 110 to ensure that the displacement and speed of the two moving along the second direction D2 are completely synchronized (or linked according to preset logic). This avoids the movement misalignment that may occur when they are installed separately, and allows the process of positioning the rubber 20 to the outer shell 10 for initial bonding to rolling and contact compaction to be seamlessly connected. After the rubber positioning mechanism 300 drives the rubber 20 to complete the initial bonding with the outer shell 10, the pressing mechanism 500 can immediately follow up and compact synchronously without additional position calibration. This not only improves the bonding efficiency, but also ensures the accurate correspondence between the initial bonding position and the rolling path, reducing bonding deviation.

[0074] See Figure 8 In some embodiments, the sliding mechanism 120 includes a slide rail 121 and a sliding seat 122. The slide rail 121 extends along the second direction D2 and is fixedly connected to the frame 100. The sliding seat 122 is slidably connected to the slide rail 121, and the mounting base 110 is mounted on the sliding seat 122.

[0075] In this embodiment, the slide rail 121 is fixed to the frame 100 along the second direction D2, and the sliding seat 122 forms a matching sliding fit with the slide rail 121. This standardized sliding structure strictly limits the degree of freedom of movement of the assembly seat 110, ensuring that the assembly seat 110 can only move smoothly back and forth along the second direction D2. This design completely eliminates possible offset, twisting or shaking during the movement, making the initial bonding position of the rubber 20 driven by the rubber positioning mechanism 300 with the outer shell 10 more accurate. At the same time, it ensures that the roller shaft 510 of the pressing mechanism 500 rolls evenly along the preset path, avoiding the offset of the bonding position or uneven rolling force caused by movement deviation, and further ensuring the consistency of product bonding quality in mass production.

[0076] See Figures 1 to 6 In some embodiments, the housing positioning mechanism 200 is slidably connected to the frame 100 via the guide mechanism 130.

[0077] In this embodiment, the outer shell positioning mechanism 200 is connected to the frame 100 through the guide mechanism 130 (such as guide rail or guide sleeve), which restricts the degree of freedom of movement (movement only along the first direction D1) to avoid deviation, shaking or jamming during movement, and ensures that the fit between the outer shell 10 and the rubber 20 is accurate and the rolling and compaction path is uniform.

[0078] See Figure 8 In some embodiments, the guide mechanism 130 includes a guide rail 131 and a guide seat 132. The guide rail 131 extends along a first direction D1 and is fixedly installed on the frame 100. The guide seat 132 is slidably connected to the guide rail 131. The housing positioning mechanism 200 is installed on the guide seat 132.

[0079] In this embodiment, the guide rail 131 is fixed to the frame 100 along the first direction D1, and the guide seat 132 forms a high-precision sliding fit with the guide rail 131. This standardized guide structure strictly limits the motion freedom of the outer shell positioning mechanism 200, ensuring that the outer shell positioning mechanism 200 can only reciprocate smoothly along the second direction D2. This design completely avoids the outer shell 10 from shifting, twisting, or shaking during movement, making the movement trajectory of the outer shell 10 completely coordinated with the movement direction of the rubber positioning mechanism 300 and the pressing mechanism 500. This ensures that the rubber 20 and the preset pasting area of ​​the outer shell 10 are accurately aligned, fundamentally solving the problem of positioning deviation in manual pasting and further ensuring the consistency of pasting position in mass production.

[0080] See Figure 1 In some embodiments, the outer casing 10 is a circular sleeve structure; the outer casing positioning mechanism 200 includes a mounting post 210, which is used to fit the inner diameter hole of the outer casing 10.

[0081] In this embodiment, for the outer shell 10 with a circular sleeve structure, a positioning method is adopted in which the mounting post 210 is fitted into the inner diameter hole of the outer shell 10. By utilizing the matching and cooperation between the inner diameter hole and the mounting post 210, a centering and positioning is formed from the inside of the outer shell 10. This can quickly and accurately determine the reference position of the outer shell 10 in the preset pasting area, so that the rubber 20 can be accurately attached to the preset pasting frame of the outer shell 10, further improving the accuracy and uniformity of the pasting position.
