Description

Technical Field

[0001] This utility model relates to the field of thermal pad application technology, and in particular to a high-precision thermal pad application device. Background Technology

[0002] In the field of electronics manufacturing, thermistors, as a key temperature-sensitive element, are widely used in various equipment. Their mounting accuracy directly affects the performance and reliability of the product. In the current technology, the mounting of thermistors usually relies on manual or semi-automatic devices. These devices use simple clamps or positioning mechanisms to fix the product and attach the thermistor. With the development of technology, some equipment has introduced guide rails and pressing mechanisms to improve the stability of positioning and operational efficiency. However, these devices still have many shortcomings in achieving high-precision mounting.

[0003] The main drawbacks of existing technologies are low positioning accuracy, cumbersome and time-consuming adjustment process, and the need for operators to repeatedly manually correct the product position, resulting in large placement errors. At the same time, the lack of effective fine-tuning mechanisms and real-time detection means that it is difficult to achieve a tight fit between the thermal sheet and the product's positioning strip, which can easily lead to offset or gaps, affecting the placement quality. In addition, existing devices cannot automatically monitor the bonding status and rely on manual visual inspection, which further increases the uncertainty and error rate of operation.

[0004] Therefore, the inventors urgently need a high-precision device for attaching thermal pads to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a high-precision thermal sheet mounting device, aiming to solve the problems of low positioning accuracy, cumbersome adjustment process, lack of effective fine-tuning mechanism and real-time detection means in the existing thermal sheet mounting devices, which result in large mounting errors, unstable bonding quality and reliance on manual visual inspection.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-precision thermal pad application device, comprising a thermal pad positioning auxiliary component, the thermal pad positioning auxiliary component comprising a dual-guide rail platform, a fine-tuning positioning mechanism symmetrically and slidably arranged on both sides of the upper end of the dual-guide rail platform, a product platform fixed in the center of the dual-guide rail platform, and a positioning pressing mechanism arranged on the rear side of the dual-guide rail platform. An L-shaped support is provided at the upper end of the product platform, the horizontal front part of the L-shaped support forms a product support surface, and the rear end forms a product positioning wall vertically upward. An elastic pad is attached to the front end face of the product positioning wall. The product is placed on the product support surface, and positioning strips are provided on both sides of the upper end of the product. Two pressing rods at the output end of the positioning pressing mechanism are respectively flush with the rear end of each positioning strip and pressed onto the product. The output end of the fine-tuning positioning mechanism is used to fine-tune and push the product so that the positioning strip is infinitely close to the front end of the pressing rod.

[0007] Based on the above, the advantages of a high-precision thermal sheet mounting device are that it solves the problems of low positioning accuracy, cumbersome adjustment process, lack of effective fine-tuning mechanism and real-time detection means in existing thermal sheet mounting devices, resulting in large mounting errors, unstable bonding quality, and reliance on manual visual inspection; mainly reflected in: 1. This utility model provides a symmetrical sliding support platform through a dual guide rail platform, which realizes the initial coarse adjustment of the fine-tuning positioning mechanism and simplifies the adjustment process. Specifically, the dual guide rail platform serves as a support structure, allowing the symmetrically configured fine-tuning positioning mechanism to slide and move on both sides of its upper end. The operator can manually push the fine-tuning positioning mechanism along the guide rail towards the center to quickly and initially position the product in the center position. This eliminates the tedious steps of repeated manual correction in the prior art, solves the problem of time-consuming adjustment process and dependence on manual operation, and improves the placement efficiency. 2. This utility model uses the output end of the fine-tuning positioning mechanism to finely adjust and push the product, making the positioning strip infinitely close to the front end of the pressing rod, achieving sub-millimeter precision fine-tuning and solving the problem of low positioning accuracy. Specifically, the output end of the fine-tuning positioning mechanism acts on the side of the product, and through components such as the fine-tuning telescopic rod, it performs fine displacement control, pushing the product to move until the positioning strip and the front end of the pressing rod are infinitely close. This provides an effective fine-tuning mechanism to ensure that the thermal sheet mounting position error is extremely small, solving the problem of large mounting error caused by insufficient positioning accuracy in the prior art. 3. This utility model provides a stable elastic positioning reference through the L-shaped support of the product platform, especially the product positioning wall and elastic pad, which solves the problem of unstable bonding quality. Specifically, the horizontal front part of the L-shaped support forms the product support surface to support the product, and its rear end forms the product positioning wall vertically upward. An elastic pad is attached to the front face. When the product is placed on the product support surface, its rear end is directly attached to the elastic pad, forming a buffer and self-adaptive positioning, avoiding the displacement caused by hard collision. This ensures that the product remains stable during fine adjustment and pressing, and solves the defect of unstable bonding quality in the prior art. 4. This utility model achieves reliable clamping and fixing by pressing the positioning pressing mechanism's pressing rods onto the product and corresponding to the rear end of the positioning strip, thus reducing mounting errors. Specifically, the output end of the positioning pressing mechanism is equipped with two pressing rods, which are flush with the rear ends of the positioning strips on both sides of the upper end of the product and directly press onto the product. After fine adjustment, the pressing rods provide uniform downward pressure, locking the positioning strips in a position close to the front end of the pressing rods. This eliminates the risk of displacement during thermal sheet bonding, solves the problem of large mounting errors caused by the lack of an effective pressing mechanism in the prior art, and reduces the reliance on manual visual inspection.

[0008] Furthermore, the fine-tuning positioning mechanism includes two sliding blocks located on the two tracks of the dual-guide rail platform, a fine-tuning mounting plate fixedly connected between the upper ends of the two sliding blocks, and a fine-tuning structure located in the middle of the upper end of the fine-tuning mounting plate. Mounting bosses and limiting bosses are provided on both sides of the middle upper end of the fine-tuning mounting plate. The fine-tuning structure includes a fine-tuning platform, a fine-tuning positioning piece, and a fine-tuning telescopic rod. The fine-tuning platform is slidably fitted between the mounting boss and the limiting boss. The fine-tuning positioning piece is fixed to the upper end of the fine-tuning platform. The fine-tuning telescopic rod is located at the front end of the mounting boss, and its output end passes through the mounting boss and connects to the fine-tuning platform. The limiting boss limits the maximum displacement distance of the fine-tuning platform.

[0009] Based on the above, the beneficial effects of the sliding block are: it enables the fine-tuning mounting plate of the fine-tuning positioning mechanism to slide smoothly along the guide rail, providing stable support for the coarse-tuning stage; the beneficial effects of the fine-tuning mounting plate are: it enables integrated installation and synchronous movement of the fine-tuning structure; the beneficial effects of the mounting boss are: it provides a fixed mounting fulcrum for the fine-tuning telescopic rod; the beneficial effects of the limiting boss are: it limits the maximum displacement distance of the fine-tuning platform; the beneficial effects of the fine-tuning platform are: it mounts the fine-tuning positioning piece and transmits the fine-tuning driving force; the beneficial effects of the fine-tuning positioning piece are: it directly contacts the side of the product, achieving precise positioning and fine-tuning guidance of the product edge; and the beneficial effects of the fine-tuning telescopic rod are: it provides precise displacement control of the fine-tuning platform, ensuring that the fine-tuning positioning piece achieves sub-millimeter-level adjustment accuracy for the product.

[0010] Furthermore, the fine-tuning positioning piece has a right-angled groove on the side near the product that matches the corner of the product, and a circular groove centered on the vertex of the right-angled groove is provided at the vertex of the right-angled groove.

[0011] Based on the above, the beneficial effects of right-angle grooves are that by adapting to the shape of the product's corners, they achieve precise positioning of the product and prevent the product from shifting or rotating during the positioning process; the beneficial effects of circular grooves are that they avoid corner damage to the product caused by rigid collisions and improve positioning tolerance by allowing for slight positional compensation.

[0012] Furthermore, the positioning and pressing mechanism also includes a hinge frame and a rotating table. The hinge frame is disposed on the rear side of the dual guide rail platform, the rotating table is hinged to the upper end of the hinge frame, and the two pressing rods are respectively fixed to the upper sides of the rotating table.

[0013] Based on the above, the beneficial effects of the hinged frame are that it provides a stable rotation fulcrum for the turntable, realizing the control of the lifting and lowering motion trajectory of the pressing rod; the beneficial effect of the turntable is that it installs two pressing rods and achieves synchronous rotation, ensuring that the pressing rods apply uniform pressure to the product.

[0014] Furthermore, each of the two fine-tuning mounting plates is provided with a positioning pin on the front side near the dual guide rail platform, and a fine-tuning side limiting plate is provided at the middle of the front end of the dual guide rail platform. The two positioning pins limit the displacement distance of the fine-tuning mounting plate by contacting the two sides of the fine-tuning side limiting plate.

[0015] Based on the above, the beneficial effect of the positioning pin is that by limiting the contact with the fine-tuning side limiting plate, the maximum displacement distance of the fine-tuning mounting plate can be precisely controlled.

[0016] Furthermore, the thermal pad attaching device also includes a camera infrared recognition component, which is mounted above the thermal pad positioning auxiliary component and is used to detect the degree of adhesion between the rear end of the positioning strip and the front end of the pressing rod.

[0017] Based on the above, the beneficial effect of the camera infrared recognition component is that it monitors the degree of fit between the rear end of the positioning strip and the front end of the pressing rod in real time through infrared detection technology, realizing automated precision detection in the mounting process and solving the uncertainty problem of traditional manual visual inspection.

[0018] Furthermore, the thermal pad application device also includes a thermal pad application machine, which is mounted directly above the product platform.

[0019] Based on the above, the beneficial effects of the thermal pad mounting machine are that it forms a vertical alignment with the precisely positioned product, realizing the accurate and automatic mounting of thermal pads and solving the problems of low efficiency and poor accuracy of traditional manual mounting.

[0020] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the following description, in conjunction with the accompanying drawings and specific embodiments, will further explain this utility model. Attached Figure Description

Positioning strips 31 are provided on both sides of the upper end of the product 3. The two pressing rods 141 at the output end of the positioning pressing mechanism 14 are respectively flush with the rear end of each positioning strip 31 and pressed onto the product 3. The output end of the fine-tuning positioning mechanism 12 is used to fine-tune and push the product 3 so that the positioning strip 31 is infinitely close to the front end of the pressing rod 141.

[0024] The fine-tuning positioning mechanism 12 includes two sliding blocks 121 located on the two tracks of the dual-guide rail platform 11, a fine-tuning mounting plate 122 fixedly connected between the upper ends of the two sliding blocks 121, and a fine-tuning structure 123 located in the middle of the upper end of the fine-tuning mounting plate 122. Mounting bosses 1221 and limiting bosses 1222 are provided on both sides of the middle of the upper end of the fine-tuning mounting plate 122. The fine-tuning structure 123 includes a fine-tuning platform 1231, a fine-tuning positioning piece 1232, and a fine-tuning telescopic rod. 1233, the fine-tuning platform 1231 is slidably fitted between the mounting boss 1221 and the limiting boss 1222, the fine-tuning positioning piece 1232 is fixed to the upper end of the fine-tuning platform 1231, the fine-tuning telescopic rod 1233 is located at the front end of the mounting boss 1221, and the output end of the fine-tuning telescopic rod 1233 passes through the mounting boss 1221 and is connected to the fine-tuning platform 1231, and the limiting boss 1222 limits the maximum displacement distance of the fine-tuning platform 1231.

[0025] The fine-tuning positioning piece 1232 has a right-angled groove 12321 on the side near the product that matches the corner of the product, and a circular groove centered on the vertex is provided at the vertex of the right-angled groove 12321.

[0026] The positioning and pressing mechanism 14 further includes a hinge frame 142 and a rotating platform 143. The hinge frame 142 is disposed on the rear side of the dual guide rail platform 11, and the rotating platform 143 is hinged to the upper end of the hinge frame 142. The two pressing rods 141 are respectively fixed to the upper sides of the rotating platform 143.

[0027] The two fine-tuning mounting plates 122 are provided with positioning pins 1223 on the front side of the side near the dual guide rail platform 11. The front middle of the dual guide rail platform 11 is provided with a fine-tuning side limiting plate 111. The two positioning pins 1223 limit the displacement distance of the fine-tuning mounting plates 122 by contacting the two sides of the fine-tuning side limiting plate 111.

[0028] The thermal sheet applicator also includes a camera infrared recognition component 2, which is mounted above the thermal sheet positioning auxiliary component 1 and is used to detect the degree of adhesion between the rear end of the positioning strip 31 and the front end of the pressing rod 141.

[0029] The thermal pad application device also includes a thermal pad application machine 4, which is mounted directly above the product platform 13.

[0030] In summary, the specific embodiments of this utility model are as follows: The operator places product 3 on the L-shaped support 131 of product platform 13, so that the rear end of product 3 is close to the elastic pad 1313 at the front end of product positioning wall 1312. At this time, the positioning strip 31 of product 3 faces upward. The operator manually pushes the fine-adjustment positioning mechanism 12 on both sides of the double guide rail platform 11 to slide along the guide rail towards the center until the right angle groove 12321 of fine-adjustment positioning piece 1232 is in contact with the side of product 3. During this process, the positioning pin 1223 at the front of fine-adjustment mounting plate 122 contacts the two sides of the fine-adjustment side limit plate 111 at the front end of the double guide rail platform 11, limiting the maximum displacement of fine-adjustment mounting plate 122 and ensuring that product 3 is positioned at the center of product support surface 1311. Subsequently, the operator rotates the rotating table 143 of the positioning and pressing mechanism 14, causing it to rotate around the hinge frame 142, which drives the two pressing rods 141 to press down onto the surface of the product 3. The front end of each pressing rod 141 is flush with the rear end of the corresponding positioning strip 31. The camera infrared recognition component 2 detects the gap between the rear end of the positioning strip 31 and the front end of the pressing rod 141 in real time. When the gap exceeds the standard, the operator manually turns the two fine-tuning telescopic rods 1233 on the left and right sides to push the fine-tuning platform 1231, so that the fine-tuning positioning piece 1232 fine-tunes the position of the product 3 until the positioning strip 31 is infinitely close to the front end of the pressing rod 141. After precise positioning is completed, the thermal pad attaching machine 4, which is set up directly above the product platform 13, presses down to accurately attach the thermal pad to the designated position of the product 3. The entire process achieves high-precision attachment through the elastic pad 1313 buffering the positioning pressure, the right-angle groove 12321 cooperating with the circular groove to prevent product corner offset, and automatic calibration by camera infrared detection.
