[0003] The drawbacks of the above technical solution are: it fails to achieve the purpose of self-adjustment of product and small parts positioning, resulting in low work efficiency, poor relative positioning between the two, and low pressing accuracy. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a positioning and pressing mechanism, a positioning and pressing method, and a pressing device for small parts on the side wall of a product.

[0005] The objective of this invention can be achieved through the following technical solutions: The product sidewall small part positioning and pressing mechanism includes: Mounting rack; The product positioning component includes a product positioning platform that is slidably mounted on the mounting bracket. The product positioning platform has a product positioning structure in its circumferential direction and a product centering structure on its back. The small part positioning assembly includes a small part pressing structure disposed on the mounting frame and located below the product positioning platform, and a small part positioning structure disposed on the small part pressing structure. The heating and pressing assembly includes a fixed heating module disposed on one side of the product positioning platform and acting on the bottom of the product, and a movable heating module disposed on the mounting bracket and acting on the top of the product.

[0006] Furthermore, the mounting bracket is equipped with an inclined mounting platform, and the mounting platform is equipped with an adjusting guide rail that is slidably connected to the product positioning platform.

[0007] Furthermore, the product positioning platform is inclinedly mounted on the mounting frame, the product positioning platform has a product adsorption cavity inside and a product adsorption hole communicating with the product adsorption cavity on the upper surface of the product positioning platform, and an annular sealing ring is provided on the product positioning platform.

[0008] Furthermore, the product positioning structure includes a fixed abutment block disposed on the mounting frame and located at the bottom of the product positioning platform, an adjustable abutment block disposed on the upper side of the mounting frame on the product positioning platform, and pressing fixing blocks disposed at intervals on the mounting frame in the circumferential direction of the product positioning platform.

[0009] Furthermore, the product centering structure includes a mounting block disposed on the mounting frame, two horizontal adjusting rods symmetrically disposed on the mounting block, a rotating adjusting rod hinged to one end of the horizontal adjusting rod protruding from the mounting block, a centering clamping block slidably connected to both sides of the mounting frame located on the product positioning platform at the end of the rotating adjusting rod away from the horizontal adjusting rod, a synchronous drive rod disposed in the mounting block and acting on the ends of the horizontal adjusting rods respectively, and a first elastic element disposed in the mounting block and acting between the two horizontal adjusting rods.

[0010] Furthermore, the small part pressing structure includes a fixed frame disposed on the mounting bracket, a pressing driver disposed on the fixed frame, a small part positioning block passing through the fixed frame at the output end of the pressing driver, and a small part adsorption cavity disposed on the small part positioning block.

[0011] Furthermore, the small part positioning structure includes a drive plate disposed at the output end of the pressing driver, a small part clamping block with a surrounding guide motion provided circumferentially at the fixed frame and located at the small part positioning block, a synchronous transmission rod with both ends respectively hinged between the drive plate and the small part clamping block, and a second elastic element disposed between the small part positioning block and the small part clamping block.

[0012] Furthermore, the movable heating module includes a lateral displacement structure disposed on the mounting bracket, a longitudinal displacement structure disposed on the lateral displacement structure, a vertical pressing structure disposed on the longitudinal displacement structure, a vertical displacement structure disposed on the vertical pressing structure, and a movable heating block disposed on the vertical displacement structure.

[0013] The present invention also provides a positioning and pressing method for a product sidewall small part positioning and pressing mechanism, the positioning and pressing method comprising the following steps: S1. Load the product onto the product positioning platform. After positioning the product on the product positioning platform using the product centering structure, fix the product's position using the product positioning structure. S2, the small part is loaded onto the small part pressing structure, and the small part is positioned on the small part pressing structure by the small part positioning structure. After the small part is fixed by the small part pressing structure, the small part is driven to press the small part from bottom to top onto the product side wall to set the installation position, forming a pressing and holding pressure state. S3, by moving the heating module downwards and pressing it on the upper part of the product near the small part pressing position, the fixed heating module located at the bottom of the product and the moving heating module located at the top of the product are activated at the same time to complete the heat pressing of the product and the small part under the pressure holding state.

[0014] The present invention also provides a pressing device having a product sidewall small part positioning and pressing mechanism as described above.

[0015] Compared with existing technologies, the side wall small part positioning and pressing mechanism of this product has the following advantages: 1. By adopting an inclined product positioning method, the product centering structure acts on the product, reducing the relative displacement between the product and the product positioning platform, and ensuring that the product is in a precise set position.

[0016] 2. The small parts are automatically positioned and clamped accurately. Then, the small parts are clamped and fixed by negative pressure adsorption at the end instead of circumferential clamping. The small parts are then pushed and pressed from bottom to top, which improves the efficiency of small parts positioning and pressing. 3. The product adopts a heating and pressing assembly with the bottom and top sides attached, which increases the uniformity of heating at the product ends and prevents movement and interference during product loading; 4. By tilting the product positioning structure, the product is positioned close to a vertical position. The small part is positioned below the product. By driving the small part from bottom to top in combination with the end adsorption positioning method, the small part can maintain a precise state to complete the positioning and pressing with the side wall of the product, thus improving the accuracy of positioning and pressing.

[0026] Example 1, please refer to Figure 1 This is a schematic diagram of a product sidewall small part positioning and pressing mechanism provided by the present invention. The product sidewall small part positioning and pressing mechanism includes: a mounting frame 10, a product positioning component 20, a small part positioning component 30, and a heating and pressing component 40 disposed on the mounting frame 10. It is conceivable that this product sidewall small part positioning and pressing mechanism also includes other functional components and specific structures, such as electrical connection components, control components, and mounting structures, all of which are technologies known to those skilled in the art, and therefore will not be described in detail here.

[0027] Please see Figure 8In this embodiment, the product is rectangular in shape, and a recessed small part mounting groove is provided on one side wall of the product; the small part is a strip-shaped structure, and the outer contour of the small part is the same as that of the small part mounting groove. Fixing adhesive is provided in the small part mounting groove or on the small part mating surface, which can play an adhesive role after melting when the set temperature is reached. In this embodiment, the small part is a strip-shaped part with a double-end arc-shaped convex surface as an example.

[0028] Please see Figures 2 to 4 In this embodiment, the mounting frame 10 is installed on a machine base or equipment platform, serving as a carrier for assembling various components. It improves the positioning height of the product and smaller parts, and provides greater circumferential space for automated operations such as loading and pressing. Specifically, the mounting frame 10 is equipped with an inclined mounting platform 11. The mounting platform 11 facilitates the installation and adjustment of various components, ensuring that the product and smaller parts are self-adjusting under their own weight. The inclination angle of the mounting platform 11 should be greater than 45°; ideally, the mounting platform 11 is approximately perpendicular to the horizontal direction of the machine base or equipment platform.

[0029] In this embodiment, the product positioning component 20 includes a product positioning platform 21 slidably mounted on the mounting frame 10. The product positioning platform 21 uses the mounting platform 11 as its base, meaning that the product positioning platform 21 and the mounting platform 11 maintain the same tilt angle to prevent the product from tipping over when initially placed on the product positioning platform 21. The outer contour of the product positioning platform 21 closely approximates the outer contour of the product, facilitating the action of the product centering structure 23 on the product. Furthermore, the mounting platform 11 is provided with an adjusting guide rail 12 that is slidably connected to the product positioning platform 21, allowing the product positioning platform 21 to move synchronously with the product, reducing the relative displacement travel between the product and the product positioning platform 21, and minimizing wear caused by displacement.

[0030] Specifically, the upper end of the product positioning platform 21 is flat, and the product positioning platform 21 has a product adsorption chamber 211 inside. The product adsorption chamber 211 is connected to a cylinder. The upper plane of the product positioning platform 21 has a product adsorption hole 212 communicating with the product adsorption chamber 211, and an annular sealing ring 213 is provided on the product positioning platform 21. The annular sealing ring 213 has two sections, which are respectively arranged circumferentially along the outer edge and the inner edge of the product adsorption hole 212. The annular sealing ring 213 seals the space between the bottom of the product and the product positioning platform 21, which facilitates the formation of negative pressure adsorption and realizes the adsorption and fixation of the bottom of the product. A recessed adsorption relief groove 214 can be provided at the edge or corner of the product positioning platform 21. The adsorption relief groove 214 forms a gap between the edge of the product and the product positioning platform 21, so as to achieve a close fit after the adsorption is released.

[0031] In this embodiment, a product positioning structure 22 is provided circumferentially on the product positioning platform 21. The product positioning structure 22 includes initial positioning for loading and secondary fixing after product adjustment. Specifically, the product positioning structure 22 includes a fixed abutment block 221 set on the mounting frame 10 and located at the bottom of the product positioning platform 21. The fixed abutment block 221 is used to support the product when it is placed on the inclined bottom of the product positioning platform 21. An adjustable abutment block 222 is provided on the mounting frame 10 on the upper side of the product positioning platform 21. The adjustable abutment block 222 is connected to a threaded cylinder. The threaded cylinder makes it easier to control the stroke of the adjustable abutment block 222 and avoids the problem of direct impact on the outer wall of the product. Pressing fixing blocks 223 are arranged at intervals circumferentially on the mounting frame 10 around the product positioning platform 21. The pressing fixing blocks 223 are connected to a planar rotary cylinder. The planar rotary cylinder adjusts the lifting height while rotating, so as to press and fix the pressing fixing blocks 223 down to the upper edge of the product and prevent the product from detaching outward under force.

[0032] In this embodiment, a product centering structure 23 is provided on the back of the product positioning platform 21. The product centering structure 23 acts on the product, enabling the product to move synchronously with the product positioning platform 21 over a long stroke and to move relative to it over a short stroke, thus completing the centering and positioning adjustment of the product and placing it in a precise set position. Specifically, the product centering structure 23 includes a mounting block 231 set on the mounting frame 10. The mounting block 231 serves as a mounting reference block, facilitating the installation of various components. The mounting block 231 has a horizontal axial connecting hole 238, through which two symmetrically arranged horizontal adjusting rods 232 are inserted. One end of each horizontal adjusting rod 232 extends out of the mounting block 231 and is hinged to a rotating adjusting rod 233. The rotating adjusting rod 233 is L-shaped to save installation space. The end of the rotating adjusting rod 233 away from the horizontal adjusting rod 232 is slidably connected to the mounting frame 10. Centering clamping blocks 234 are located on both sides of the product positioning platform 21. These blocks 234 are slidably mounted on the mounting platform 11 via guide rails, with the sliding direction being the same as that of the product positioning platform 21. A first elastic element 237, a spring, is disposed within the mounting block 231 and acts between two horizontal adjusting rods 232. The elastic potential energy generated by the first elastic element 237 forces the two horizontal adjusting rods 232 to tend to move outwards. After rotation of the adjusting rod 233, the centering clamping blocks 234 are axially clamped inwards. The mounting block 231 also includes synchronous drive rods 235, with both ends acting on the ends of the horizontal adjusting rods 232. An adjusting guide rod 236, perpendicular to the moving direction of the horizontal adjusting rods 232, is also provided in the mounting block 231. The synchronous drive rod 235 is sleeved on the adjusting guide rod 236 and connected to a centering driver and a cylinder, for guiding the synchronous drive rod 235 along the adjusting guide rod 236. The synchronous drive rod 235 is U-shaped. By driving the synchronous drive rod 235, it acts on both ends of the horizontal adjusting rod 232, ultimately driving the centering clamping block 234 to move axially outward to form a centering open state. Rollers are provided at the hinge at the end of the horizontal adjusting rod 232 to improve the smoothness of the drive.

[0033] Optimally, an edge notch 215 is provided at the edge of the product positioning platform 21, and a corresponding protruding centering abutment 239 is provided on the centering clamping block 234. The centering abutment 239 abuts against the side wall of the product and can be finely adjusted at the edge notch 215, reducing the area of ​​force on the product and improving the accuracy of positioning adjustment.

[0034] Please see Figures 5 to 6In this embodiment, the small part positioning assembly 30 includes a small part pressing structure 31 disposed on the mounting frame 10 and located below the product positioning platform 21. The small part pressing structure 31 is used to fix the small part and push it directly into the small part mounting groove on the side wall of the product. A small part positioning structure 32 is provided on the small part pressing structure 31. The small part positioning structure 32 is used to adjust the positioning state of the small part on the small part pressing structure 31 to make it converge to the optimal state. Specifically, the small part pressing structure 31 includes a fixing frame 311 disposed on the mounting frame 10. The fixing frame 311 consists of two spaced plates with guide posts between the plates. A pressing driver 312 is provided on the fixing frame 311. The pressing driver 312 is a cylinder that drives the small part to press directly. A small part positioning block 313 is provided at the output end of the pressing driver 312 and passes through the fixing frame 311. The circumferential contour of the small part is consistent with the end size of the small part positioning block 313 or the circumferential edge of the small part protrudes beyond the end of the small part positioning block 313. A small part adsorption cavity 314 is provided on the small part positioning block 313. The small part positioning block 313 is connected to a cylinder, which can provide a negative pressure function for the small part adsorption cavity 314 to be controlled by an on / off switch. After the small part is first adjusted by the small part positioning structure 32, the small part adsorption cavity 314 adsorbs and fixes the small part, keeping the small part close to the end of the small part positioning block 313. The pressure driver 312 directly pushes the small part to adhere to the side wall of the product, and provides the small part with a force-holding pressure state during the subsequent heating and pressing process.

[0035] In this embodiment, the small part positioning structure 32 includes a drive plate 321 disposed at the output end of the press driver 312. The drive plate 321 is driven synchronously with the small part positioning block 313. Small part clamping blocks 322 are provided on the fixed frame 311 at circumferential intervals around the small part positioning block 313 for enclosing and guiding movement. The fixed frame 311 is provided with an inclined guide hole 325 for the small part clamping block 322 to pass through at an incline, and synchronous transmission rods 323 are respectively hinged at both ends between the drive plate 321 and the small part clamping block 322. The press driver 312 drives the drive plate 321 to drive the multiple synchronous transmission rods 323 to rotate, and the rotated small part clamping block 322 moves along the inclined guide hole 325 to complete the folding and opening of the small part clamping block 322 around the small part positioning block 313. Small parts need to be loaded when the small part positioning block 313 is in a semi-closed state, ensuring sufficient space between the small part positioning block 313, the product side wall, and the small part clamping block 322. While driving the small part positioning block 313 to pull back, the small part clamping block 322 retracts and, under its own gravity, adheres to the end of the small part positioning block 313, activating the negative pressure adsorption of the small part adsorption chamber 314. Then, the small part positioning block 313 is driven to push and press against the product side wall. This automatic positioning and precise clamping of the small part, combined with end negative pressure adsorption replacing circumferential clamping, and subsequent upward pushing and pressing, improves the efficiency of small part positioning and pressing.

[0036] Optimally, a second elastic element 324 is provided between the small part positioning block 313 and the small part clamping block 322. The second elastic element 324 is a spring. The small part clamping block 322 and the inclined guide hole 325 are in a close-fitting guide. Adding the second elastic element 324 can keep the small part clamping block 322 in a stressed state at all times, avoiding the problem of material jamming.

[0037] Please see Figure 2 , Figure 7 In this embodiment, the heating and pressing assembly 40 includes a fixed heating module 41 disposed on one side of the product positioning platform 21 and acting on the bottom of the product. An installation notch 13 is provided at the corner of the product positioning platform 21 near the small part positioning and pressing position. The fixed heating module 41 is positioned at the installation notch 13. When the product is positioned on the product positioning platform 21, the bottom surface of the product near the small part positioning and pressing position is in contact with the fixed heating module 41. A fixed abutment block 221 is also provided on the fixing frame 311 to support the lower end of the product. The product can completely fit the outside of the fixed heating module 41, and an outer heat insulation baffle 411 is provided around the fixed heating module 41 to avoid material loading safety issues and glue melting issues before small part loading and pressing.

[0038] In this embodiment, a movable heating module 42 is provided on the mounting frame 10 and acts on the upper end of the product. The movable heating module 42 is used to fit against the upper surface of the product, increasing the uniformity of heating at the end of the product and preventing movement interference during product loading. Specifically, the movable heating module 42 includes a lateral displacement structure 421 provided on the mounting frame 10. The lateral displacement structure 421 includes a slidably connected lateral guide rail and a lateral slider, and a lateral cylinder for driving the lateral slider, used to adjust the lateral displacement of the movable heating block 425. A longitudinal displacement structure 422 is provided on the lateral displacement structure 421. The longitudinal displacement structure 422 includes a slidably connected longitudinal guide post and a longitudinal slider, and a longitudinal cylinder for driving the longitudinal slider, used to adjust the longitudinal displacement of the movable heating block 425. A vertical pressing structure 423 is provided on the longitudinal displacement structure 422. The vertical pressing structure 423 includes a vertical guide rail and a vertical slider that are slidably connected, as well as a vertical cylinder that drives the vertical slider, for adjusting the vertical displacement of the moving heating block 425. A vertical limiting block is provided on the longitudinal slider to limit the excessive movement of the vertical slider.

[0039] In addition, a vertical displacement structure 424 is provided on the vertical pressing structure 423. The vertical displacement structure 424 is a cylinder direct drive method, which is used to move the heating block 425 vertically until it is attached to the upper surface of the product. The end of the moving heating block 425 is provided with an L-shaped bonding surface 426, which is attached to the edge of the product to improve the bonding stability.

[0040] In this embodiment, the fixed heating module 41 and the movable heating block 425 can be rapidly heated using internal heating wires, heating rods, or other heat transfer methods.

[0041] Example 2: The present invention also provides a positioning and pressing method for a product sidewall small part positioning and pressing mechanism, the positioning and pressing method comprising the following steps: S1, the product is loaded onto the product positioning platform 21, and the product is positioned on the product positioning platform 21 by the product centering structure 23, and then the product position is fixed by the product positioning structure 22. S2, the small part is loaded onto the small part pressing structure 31, and the small part is positioned on the small part pressing structure 31 by the small part positioning structure 32. After the small part is fixed by the small part pressing structure 31, the small part is driven to press from bottom to top onto the product side wall to set the installation position, forming a pressing and holding state. S3, the moving heating module 42 moves down and presses on the upper part of the product near the small part pressing position, and at the same time, the fixed heating module 41 located at the bottom of the product and the moving heating module 42 located at the top of the product are activated to complete the heat pressing of the product and the small part under the pressure holding state.

[0042] By tilting the product positioning structure 22, the product is positioned close to a vertical position. The small part is positioned below the product. By driving the small part from bottom to top in combination with the end adsorption positioning method, the small part can maintain a precise state to complete the positioning and pressing with the side wall of the product, thereby improving the accuracy of positioning and pressing.

[0043] Example 3: The present invention also provides a pressing device having a product sidewall small part positioning and pressing mechanism as described above. Except for the product sidewall small part positioning and pressing mechanism, the other components are all prior art or commercially available parts.
