Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and more specifically, to a molding and forming equipment and method for automotive sealing strips. Background Technology

[0002] Automotive weatherstripping is typically made of rubber or other soft materials, possessing a degree of elasticity and durability. It is installed on car doors, windows, trunks, and hoods to provide protection, sound insulation, and sealing. After being formed into strips using methods such as injection molding, the strips have relatively long openings along their extension direction. Therefore, the openings of the strips require edge-pressing to ensure a neater, smoother, and more aesthetically pleasing finish, as well as to increase the strength and stability of the sealing strip.

[0003] In related technologies, the edge pressing of automotive sealing strips is usually performed manually to form a sealed strip with a closed cross section. However, due to the instability of the pressure applied by manual pressing, some areas of the automotive sealing strip may be under-pressed or over-pressed (uneven pressing), which affects the edge pressing quality and efficiency of the automotive sealing strip. Summary of the Invention

[0004] The problem solved by this invention is how to uniformly press the edges of automotive sealing strips.

[0005] To address the aforementioned problems, this invention provides a sealing strip edge-forming device, comprising a worktable, a slide rail structure, a positioning clamping device, a transmission structure, and two edge-forming devices. The slide rail structure and the transmission structure are spaced apart and parallel to each other on the worktable. The positioning clamping device is provided with a positioning groove and is located between the two ends of the slide rail structure. The two edge-forming devices are respectively located at both ends of the positioning clamping device along the extension direction of the slide rail structure.

[0006] The edge-fitting and forming device includes a first movable plate, a first translation drive unit, and an edge-fitting and forming fixture. The first movable plate is slidably mounted on the slide rail structure. The first translation drive unit and the edge-fitting and forming fixture are respectively disposed on the first movable plate. The edge-fitting and forming fixture is provided with a forming groove. The positioning groove and the forming grooves on the two edge-fitting and forming fixtures together form a mounting position, which is used to install the product. The first translation drive unit is connected to the transmission structure and is used to drive the first movable plate to move along the slide rail structure to move closer to or away from the positioning fixture device.

[0007] Optionally, the edge-sealing forming fixture includes a first support wheel, two forming drive cylinders, and two forming fixture assemblies. The two forming drive cylinders and the two forming fixture assemblies are spaced apart along an extension direction perpendicular to the slide rail structure. A forming groove is formed between the two forming fixture assemblies. The first support wheel is mounted on the first moving plate and is located in the forming groove. The two forming drive cylinders are used to drive the two forming fixture assemblies to form or release the product, respectively.

[0008] Optionally, the edge-sealing and forming device further includes a second support wheel and an adjusting plate. The second support wheel is mounted on the adjusting plate and is located on the side of the first support wheel away from the positioning clamp device. The adjusting plate is detachably mounted on the first movable plate, and the position of the adjusting plate on the first movable plate is adjustable.

[0009] Optionally, the forming fixture assembly includes a mounting frame, a first pin, and a first forming roller. The first pin is vertically mounted in the mounting frame, and the first forming roller is sleeved on the first pin. When the two first forming rollers in the two forming fixture assemblies are close together, they form the product.

[0010] Optionally, the forming clamp assembly further includes a second pin and a second forming roller. The second pin is vertically disposed within the mounting frame, and the second forming roller is sleeved on the second pin and located on the side of the first forming roller away from the positioning clamp device.

[0011] Optionally, the forming fixture assembly further includes a limiting plate, which is mounted on the mounting frame and located on the side away from the positioning fixture device. The limiting plate has a limiting groove, and the two limiting grooves in the two forming fixture assemblies are closed to form an annular limiting groove, which matches the size of the product.

[0012] Optionally, the positioning clamping device includes a second movable plate and a positioning clamping assembly disposed on the second movable plate; the positioning clamping assembly includes a positioning drive cylinder, two clamping mounting plates, a fixed clamping block, and a movable clamping block. The second movable plate is slidably mounted on the slide rail structure. The positioning drive cylinder and one of the clamping mounting plates are spaced apart on the second movable plate along an extension direction perpendicular to the slide rail structure. The fixed clamping block is mounted on the second movable plate through one of the clamping mounting plates. The movable clamping block is mounted on the other clamping mounting plate. The positioning drive cylinder is connected to the other clamping mounting plate and is used to drive the movable clamping block to move closer to or away from the fixed clamping block to position, clamp, or release the product.

[0013] Optionally, the fixed clamping block and the movable clamping block are respectively detachably mounted on the two clamp mounting plates.

[0014] Optionally, the positioning fixture device further includes a second translation drive unit, which is mounted on the second moving plate and is connected to the transmission structure for driving the second moving plate to move the positioning fixture assembly along the extension direction of the slide rail structure.

[0015] Compared with the prior art, before the product is pressed and folded, the present invention first uses two first translational drive units in two pressing and folding devices to cooperate with the transmission structure to drive two pressing and folding fixtures to move to a position adjacent to the positioning fixture device. The product is then installed in the mounting position formed by the positioning groove and the two pressing grooves. The positioning fixture device positions and clamps the middle part of the product. The two ends of the product pass through the two pressing and folding devices respectively to complete the installation of the product. Subsequently, the two first translational drive units in the two pressing and folding devices cooperate with the transmission structure. The two edge-forming clamps are driven to move away from the positioning clamping device. In other words, the two edge-forming clamps move from the part of the product that is positioned and clamped by the positioning clamping device to both ends of the product until the two ends of the product are disengaged from the edge-forming clamps of the two edge-forming devices. This allows for edge-forming of the open part of the product in the extension direction to form a sealing strip with a closed cross section. Since the pressing force of the edge-forming clamps on the product is uniform and stable during the edge-forming process, the edge-forming quality and efficiency of products such as automotive sealing strips are effectively improved.

[0016] The present invention also provides a method for edge pressing of automotive sealing strips, based on the edge pressing equipment for automotive sealing strips as described above, comprising the following steps:

[0017] Install the product in the mounting position;

[0018] The product is positioned and clamped by a positioning clamping device;

[0019] The product is pressed by the edge pressing fixtures in the two edge pressing devices. The first translation drive unit in the two edge pressing devices is driven by the transmission structure to drive the first moving plate to move away from the positioning fixture device along the slide rail structure so as to press the edge of the product in the extension direction area.

[0020] The two edge-pressing clamps release the product, and the positioning clamp device releases the product.

[0021] Therefore, since the edge-fitting method for automotive sealing strips is based on the edge-fitting equipment for automotive sealing strips as described above, the edge-fitting method for automotive sealing strips has at least all the technical effects of the edge-fitting equipment for automotive sealing strips, which will not be elaborated further here.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0033] To solve the above technical problems, combined with Figure 1 As shown, this embodiment of the invention provides a sealing strip edge pressing device, including a worktable 1, a slide rail structure 2, a positioning clamp device 4, a transmission structure 3, and two edge pressing devices 5. The slide rail structure 2 and the transmission structure 3 are installed on the worktable 1 at intervals and in parallel. The positioning clamp device 4 is provided with a positioning groove and is located between the two ends of the slide rail structure 2. The two edge pressing devices 5 are respectively located at both ends of the positioning clamp device 4 along the extension direction of the slide rail structure 2.

[0034] The edge-fitting and forming device 5 includes a first movable plate 51, a first translation drive unit 52, and an edge-fitting and forming fixture 53. The first movable plate 51 is slidably mounted on the slide rail structure 2. The first translation drive unit 52 and the edge-fitting and forming fixture 53 are respectively disposed on the first movable plate 51. The edge-fitting and forming fixture 53 is provided with a forming groove. The positioning groove and the forming grooves on the two edge-fitting and forming fixtures 53 together form a mounting position, which is used to install the product 6. The first translation drive unit 52 is connected to the transmission structure 3 and is used to drive the first movable plate 51 to move along the slide rail structure 2 to approach or move away from the positioning fixture device 4.

[0035] It should be noted that the positioning clamping device 4 is used to position and clamp a certain part between the two ends of the product 6; the first translation drive unit 52, which is set on the first moving plate 51, is driven to connect with the transmission structure 3. The transmission structure 3 is parallel to the slide rail structure 2, and the first moving plate 51 is slidably installed on the slide rail structure 2, so that the first moving plate 51 can drive the edge pressing clamp 53 to move along the slide rail structure 2 under the cooperation of the first translation drive unit 52 and the transmission structure 3, so as to move closer to or away from the positioning clamping device 4.

[0036] Before the edge-fitting and molding operation of product 6, the two edge-fitting and molding devices 5 can move towards the positioning clamp device 4 until they are arranged close to the positioning clamp device 4. After the product 6 is placed in the installation position and positioned and clamped by the positioning clamp device 4, the two edge-fitting and molding devices 5 move from the part of the product 6 that is positioned and clamped by the positioning clamp device 4 to both ends of the product 6. This allows the two edge-fitting and molding devices 5 to start the molding operation from a certain part between the two ends of the product 6, which is equivalent to performing the edge-fitting and molding operation from the middle of the product 6 to both ends at the same time, thereby effectively improving the edge-fitting and molding quality and efficiency of product 6.

[0037] The extension direction of slide rail structure 2 is in line with Figure 1 The X-axis of the coordinate system is parallel and also refers to the left-right direction, while the direction perpendicular to the extension of slide rail structure 2 is... Figure 1 The Y-axis of the coordinate system is parallel, and it also refers to the forward and backward direction.

[0038] Before the edge-fitting and molding operation on product 6, in this embodiment, the two first translational drive units 52 in the two edge-fitting and molding devices 5 cooperate with the transmission structure 3 to drive the two edge-fitting and molding fixtures 53 to move to a position adjacent to the positioning fixture device 4. Product 6 is then installed in the mounting position formed by the positioning groove and the two molding grooves. The positioning fixture device 4 clamps and positions the middle part of product 6. Both ends of product 6 pass through the two edge-fitting and molding devices 5 respectively, completing the installation of product 6. Subsequently, the two first translational drive units 52 in the two edge-fitting and molding devices 5 cooperate with the transmission structure 3 to drive the two edge-fitting and molding fixtures 53 to move to a position adjacent to the positioning fixture device 4. The two edge-fitting clamps 53 move away from the positioning clamp device 4 respectively. In other words, the two edge-fitting clamps 53 move from the part of the product 6 that is positioned and clamped by the positioning clamp device 4 to both ends of the product 6 until both ends of the product 6 are disengaged from the edge-fitting clamps 53 of the two edge-fitting devices 5. This allows for edge-fitting of the opening part of the product 6 in the extension direction to form a sealing strip with a closed cross section. Since the pressing force of the edge-fitting clamps 53 on the product 6 is uniform and stable during the edge-fitting process, the edge-fitting quality and efficiency of the product 6, such as automotive sealing strips, are effectively improved.

[0039] In one embodiment of the present invention, the edge-sealing and forming device 5 further includes a first sliding block structure, which is disposed on the first moving plate 51, and the first moving plate 51 is slidably connected to the slide rail structure 2 through the first sliding block structure.

[0040] It should be noted that the first movable plate 51 is slidably connected to the slide rail structure 2 disposed on the worktable 1 through the first sliding block structure, thereby improving the smoothness of the movement of the first movable plate 51 relative to the worktable 1. The number of first sliding block structures and slide rail structures 2 are matched.

[0041] In one embodiment of the present invention, the first translation drive unit 52 includes a first drive motor and a first drive gear, the transmission structure 3 is a rack structure, the first drive motor is mounted on the first moving plate 51, the first drive motor is drivenly connected to the first drive gear, and the first drive gear is meshed with the rack structure.

[0042] It should be noted that when the edge-fitting and forming device 5 needs to move along the extension direction of the slide rail structure 2, the first drive motor works to drive the first drive gear to rotate. The first drive gear meshes with the transmission structure 3, which is a rack structure. The transmission structure 3 is fixedly installed on the worktable 1. The rotational motion of the motor shaft of the first drive motor is converted into the linear reciprocating motion of the first moving plate 51 through the meshing connection of the first drive gear and the rack structure. This enables the first moving plate 51, the first translation drive part 52 installed on the first moving plate 51, and the edge-fitting and forming fixture 53 to move closer to or away from the positioning fixture device 4.

[0043] Specifically, the first drive gear is positioned below the first moving plate 51, so that the rotation of the first drive gear will not interfere with the linear movement of the first moving plate 51.

[0044] In one embodiment of the present invention, combined with Figure 2 and Figure 3 As shown, the edge-sealing forming fixture 53 includes a first support wheel 531, two forming drive cylinders 532, and two forming fixture assemblies 533. The two forming drive cylinders 532 and the two forming fixture assemblies 533 are all spaced apart along the extension direction perpendicular to the slide rail structure 2. The forming groove is formed between the two forming fixture assemblies 533. The first support wheel 531 is mounted on the first moving plate 51 and is located in the forming groove. The two forming drive cylinders 532 are used to drive the two forming fixture assemblies 533 to form or release the product 6 respectively.

[0045] It should be noted that before product 6 is pressed, the two pressing fixture assemblies 533 in the edge-joining pressing fixture 53 are spaced apart and form the pressing groove between them. Then, the corresponding part of product 6 is placed on the first support wheel 531 within the pressing groove. At this time, the first support wheel 531 positions and supports product 6, ensuring that product 6 is at a suitable pressing height. When product 6 is pressed, the two pressing drive cylinders 532 operate to drive the two pressing fixture assemblies 533 closer together to a suitable position, completing the installation and clamping of product 6 (applying a certain clamping force to product 6). Subsequently, the first translation drive unit 52 in the two edge-joining pressing devices 5 engages with the transmission structure 3 to drive the two... The edge-fitting and forming fixture 53 moves from the part of the product 6 that is clamped by the positioning fixture device 4 towards both ends of the product 6. During the movement, the two forming fixture components 533 in the edge-fitting and forming fixture 53 always exert a certain forming force on the product 6 to perform edge-fitting and forming operations on the product 6 in the opening area in the extension direction. After the product 6 is formed, the two ends of the product 6 are disengaged from the two edge-fitting and forming devices 5, and the two forming drive cylinders 532 work again to drive the two forming fixture components 533 to release the product 6, so that the operator can take out the formed product 6. Finally, the two edge-fitting and forming devices 5 move towards the positioning fixture device 4 to prepare for the next edge-fitting and forming operation.

[0046] Specifically, the edge-fitting and forming fixture 53 may include a first rotating shaft and a support wheel frame. The first support wheel 531 can be mounted on the support wheel frame of the worktable 1 through the first rotating shaft and is located in the middle of the two forming fixture assemblies 533. The first support wheel 531 rotates relative to the support wheel frame, so that the product 6 rotates relative to the product 6 during the edge-fitting and forming operation when the edge-fitting and forming device 5 is in the process of moving, thereby reducing the friction between the first support wheel 531 and the product 6, and thus reducing the wear of the first support wheel 531 during the edge-fitting and forming of the product 6.

[0047] In one embodiment of the present invention, combined with Figure 2 As shown, the edge-sealing and forming device 5 further includes a second support wheel 54 and an adjusting plate 55. The second support wheel 54 is mounted on the adjusting plate 55 and is located on the side of the first support wheel 531 away from the positioning clamp device 4. The adjusting plate 55 is detachably mounted on the first moving plate 51, and the position of the adjusting plate 55 on the first moving plate 51 is adjustable.

[0048] It should be noted that the second support wheel 54 can be mounted on the first moving plate 51 via the adjusting plate 55. Since the second support wheel 54 is mounted on the adjusting plate 55 and is located on the side of the first support wheel 531 away from the positioning fixture device 4, when the edge-closing forming fixture 53 moves away from the positioning fixture device 4, it performs edge-closing forming on the opening part of the product 6 in the extension direction. The second support wheel 54 supports the part of the product 6 on the side of the positioning fixture device 4 to prevent the product 6 from sinking in the part outside the positioning fixture device 4. This ensures that the part of the product 6 in the extension direction is basically at the same height throughout the forming process, thereby further improving the edge-closing forming quality of the product 6.

[0049] Furthermore, since the adjusting plate 55 is detachably mounted on the first moving plate 51, and the position of the adjusting plate 55 on the first moving plate 51 is adjustable, the position of the adjusting plate 55 on the first moving plate 51 can be adjusted according to the different lengths of the edge-joining and forming product 6, so that the second support wheel 54 can always provide support during the entire edge-joining and forming process of the product 6. In other words, the position of the second support wheel 54 in the edge-joining and forming device 5 on the first moving plate 51 can be adjusted according to different models and lengths of the product 6, thereby improving the versatility of the edge-joining and forming device 5.

[0050] Specifically, a strip hole is provided on the adjusting plate 55, and the adjusting plate 55 can be adjusted in position on the first moving plate 51 by means of bolt fasteners passing through the strip hole and the first moving plate 51.

[0051] In one embodiment of the present invention, combined with Figure 3 As shown, the forming fixture assembly 533 includes a mounting frame 5331, a first pin 5332, and a first forming roller 5333. The first pin 5332 is vertically mounted in the mounting frame 5331, and the first forming roller 5333 is sleeved on the first pin 5332. When the two first forming rollers 5333 in the two forming fixture assemblies 5333 are close together, they form the product 6.

[0052] It should be noted that, Figure 3This is a partial structural diagram of the left-side edge-fitting forming fixture 53. The right-side edge-fitting forming fixture 53 is axially symmetrical to the left-side edge-fitting forming fixture 53, and will not be described in detail here. Taking the edge-fitting forming device 5 forming the left side of the middle position of the product 6 as an example: When one side of the middle part of the product 6 is in the forming groove between the two forming fixture assemblies 533, the first support wheel 531 supports the product 6 from below. Then, the two forming drive cylinders 532 in the left-side edge-fitting forming device 5 work to drive the two forming cylinders respectively. The two forming jig assemblies 533 approach each other so that the two first forming rollers 5333 in the two forming jig assemblies 533 approach each other to form the product 6. Then, the first translation drive 52 in the left edge forming device 5 cooperates with the transmission structure 3 so that the left edge forming device 5 moves towards the left end of the product 6. During the movement, the two first forming rollers 5333 on the left rotate around their respective first pins 5332, thereby realizing the rapid edge forming operation of the opening part of the product 6 in the extension direction during the rotation.

[0053] Specifically, the mounting bracket 5331 provides a mounting base for the first pin 5332 and the first forming roller 5333; since the first pin 5332 is vertically mounted in the mounting bracket 5331, the first forming roller 5333 rotates around the axis of the first pin 5332.

[0054] In one embodiment of the present invention, combined with Figure 3 As shown, the forming clamp assembly 533 further includes a second pin 5334 and a second forming roller 5335. The second pin 5334 is vertically disposed within the mounting bracket 5331, and the second forming roller 5335 is sleeved on the second pin 5334 and located on the side of the first forming roller 5333 away from the positioning clamp device 4.

[0055] It should be noted that since the second forming roller 5335 is located on the side of the first forming roller 5333 away from the positioning fixture device 4, it is equivalent to increasing the forming length of the forming roller in the extension direction of the product 6, so that the first forming roller 5333 and the second forming roller 5335 sequentially squeeze the same part of the product 6 in the extension direction, thereby effectively improving the edge forming effect of the product 6.

[0056] In the edge-joining forming device 5, one of the forming fixture components 533 further includes a third roller 5336, which is sleeved on the second pin 5334 and located above the second forming roller 5335. The diameter of the third roller 5336 is larger than that of the second forming roller 5335. The third roller 5336 in one forming fixture component 533 is in contact with the second forming roller 5335 in the corresponding forming fixture component 533, thereby allowing the third roller 5336 to upper limit the product 6 from above. When the two first forming rollers 5333 perform edge-joining forming operations on the current part of the product 6 in the extension direction, the third roller 5336 and the second forming roller 5335 cooperate to effectively upper limit the adjacent parts of the product 6 being formed from above, so that the current part of the product 6 being formed and the adjacent parts are at the same height, further effectively improving the forming quality of the product 6.

[0057] Specifically, in the left-side edge-sealing forming device 5, the third roller 5336 and the second forming roller 5335 are located to the left of the first forming roller 5333; in the right-side edge-sealing forming device 5, the third roller 5336 and the second forming roller 5335 are located to the right of the first forming roller 5333.

[0058] In one embodiment of the present invention, combined with Figure 3 As shown, the forming fixture assembly 533 also includes a limiting plate 5337, which is mounted on the mounting bracket 5331 and located on the side away from the positioning fixture device 4. A limiting groove is formed on the limiting plate 5337, and the two limiting grooves in the two forming fixture assemblies 533 surround each other to form an annular limiting groove, which matches the size of the product 6.

[0059] It should be noted that by installing the limiting plate 5337 on the mounting frame 5331 and placing it on the side away from the positioning fixture device 4, a limiting groove is opened on each limiting plate 5337, and the two limiting grooves in the two forming fixture assemblies 533 are joined together to form an annular limiting groove. This ensures that the adjacent position of the product 6 away from the positioning fixture device 4 in the forming position of the first forming roller is within the annular limiting groove. This allows the annular limiting groove to not only support the adjacent part of the product 6 being formed, so that the adjacent part is at the same height as the forming position, and the forming area of ​​the product 6 can be kept uniform, but also to limit and guide the adjacent part of the product 6 being formed, so as to prevent the adjacent part of the product 6 being formed from deviating from the forming height, thereby further improving the quality of forming the edges of the product 6.

[0060] Specifically, the limiting plate 5337 is vertically arranged so that the limiting groove on the limiting plate 5337 is also vertically arranged.

[0061] In one embodiment of the present invention, combined with Figure 4 As shown, the positioning clamping device 4 includes a second movable plate 41 and a positioning clamping assembly 42 disposed on the second movable plate 41. The positioning clamping assembly 42 includes a positioning drive cylinder 421, two clamping mounting plates 422, a fixed clamping block 423, and a movable clamping block 424. The second movable plate 41 is slidably mounted on the slide rail structure 2. The positioning drive cylinder 421 and one of the clamping mounting plates 422 are spaced apart on the second movable plate 41 along an extension direction perpendicular to the slide rail structure 2. The fixed clamping block 423 is mounted on the second movable plate 41 through one of the clamping mounting plates 422. The movable clamping block 424 is mounted on the other clamping mounting plate 422. The positioning drive cylinder 421 is connected to the other clamping mounting plate 422 and is used to drive the movable clamping block 424 to move closer to or away from the fixed clamping block 423 to position, clamp, or release the product 6.

[0062] It should be noted that by sliding the second movable plate 41 onto the slide rail structure 2 and setting the positioning clamp assembly 42 on the second movable plate 41, the position of the second movable plate 41 on the workbench 1 can be flexibly adjusted according to different models of products 6 on site, so as to adjust the position of the positioning clamp assembly 42 accordingly. The positioning groove is formed between the fixed clamping block 423 and the movable clamping block 424.

[0063] During the positioning and clamping operation of product 6, a certain position between the two ends of product 6, such as the middle position, is first determined to be within the positioning groove. Then, the positioning drive cylinder 421 operates to drive the movable clamping block 424 towards the fixed clamping block 423 by driving the other clamp mounting plate 422. When it reaches the preset position, the interaction between the movable clamping block 424 and the fixed clamping block 423 achieves the positioning and clamping operation of the middle position of product 6, thereby preparing for the edge-fitting and forming operation of product 6 by the two edge-fitting and forming devices 5. After the edge-fitting and forming operation of product 6 is completed, the positioning drive cylinder 421 operates to drive the movable clamping block 424 away from the fixed clamping block 423 to release the formed product 6, so that the operator can remove the formed product 6.

[0064] Specifically, the positioning fixture device 4 further includes a second slide structure, which is disposed on the second movable plate 41. The second movable plate 41 is slidably connected to the slide rail structure 2 via the second slide structure. It should be noted that the second movable plate 41 is slidably connected to the slide rail structure 2 disposed on the worktable 1 via the second slide structure, thereby improving the smoothness of movement of the second movable plate 41 relative to the worktable 1. The number of second slide structures matches the number of slide rail structures 2.

[0065] In one embodiment of the present invention, combined with Figure 5 As shown, the fixed clamping block 423 and the movable clamping block 424 are respectively detachably installed on the two clamp mounting plates 422.

[0066] It should be noted that the shapes of the opposite sidewalls of the fixed clamping block 423 and the movable clamping block 424 are matched. For example, when the sidewall of the movable clamping block 424 has a groove structure, the opposite sidewall of the fixed clamping block 423 has a protrusion structure, thereby making the product 6 more securely positioned and pressed. Since the fixed clamping block 423 and the movable clamping block 424 are respectively detachably mounted on the two clamping mounting plates 422, in other words, the fixed clamping block 423 and the movable clamping block 424 can be removed and replaced from their respective clamping mounting plates 422, thereby adapting to different models of products 6, such as sealing strips, and thus improving the versatility of the positioning clamping device 4.

[0067] Specifically, taking the example of a fixed clamping block 423 being detachably installed on a fixture mounting plate 422, the positioning fixture assembly 42 includes a connecting plate and fastening bolts. The fixture mounting plate 422 is provided with a guide block, and the side wall of the fixed clamping block 423 away from the moving block is provided with a guide groove that matches the guide block. The guide groove of the fixed clamping block 423 is slidably connected to the guide block on the fixture mounting plate 422. The fastening bolts pass through the connecting plate and the guide block, and the connecting plate is located above the fixed clamping block 423 and the guide block, and is in contact with the fixed clamping block 423 and the guide block, thereby limiting the fixed clamping block 423 to the fixture mounting plate 422 from above through the connecting plate. When it is necessary to replace the fixed clamping block 423, it is only necessary to remove the connecting plate and the fastening bolts to replace the fixed clamping block 423.

[0068] In one embodiment of the present invention, combined with Figure 4 As shown, the positioning clamp device 4 further includes a second translation drive unit 43, which is mounted on the second moving plate 41. The second translation drive unit 43 is connected to the transmission structure 3 and is used to drive the second moving plate 41 to move the positioning clamp assembly 42 along the extension direction of the slide rail structure 2.

[0069] It should be noted that the second translation drive unit 43, which is set on the second moving plate 41, is connected to the transmission structure 3, and the second moving plate 41 is slidably mounted on the slide rail structure 2, so that the second moving plate 41 can drive the positioning clamp assembly 42 to position and clamp or release the product 6 under the cooperation of the second translation drive unit 43 and the transmission structure 3.

[0070] The second translation drive unit 43 includes a second drive motor and a second drive gear. The transmission structure 3 is a rack and pinion structure. The second drive motor is mounted on the second moving plate 41. The second drive motor is driven by the second drive gear, and the second drive gear is meshed with the rack and pinion structure.

[0071] It should be noted that when the positioning fixture assembly 42 needs to be adjusted in position along the extension direction of the slide rail structure 2, the second drive motor works to drive the second drive gear to rotate. The second drive gear meshes with the transmission structure 3, which is a rack and pinion structure. The transmission structure 3 is fixedly installed on the worktable 1. The rotational motion of the motor shaft of the second drive motor is converted into the linear reciprocating motion of the second moving plate 41 through the meshing connection of the second drive gear and the rack and pinion structure. This realizes the adjustment of the position of the second moving plate 41, the second translation drive unit 43 installed on the second moving plate 41, and the positioning fixture assembly 42 on the worktable 1.

[0072] Specifically, the second drive gear is positioned below the second moving plate 41, so that the rotation of the second drive gear does not interfere with the linear movement of the second moving plate 41.

[0073] Another embodiment of the present invention provides a method for edge pressing of automotive sealing strips, based on the edge pressing equipment for automotive sealing strips described in the above embodiment, including the following steps:

[0074] S1. Install product 6 in the mounting position.

[0075] It should be noted that product 6 can be placed on the mounting position manually or by a robotic arm to realize the loading process of product 6.

[0076] S2. Position and clamp the product 6 using the positioning clamping device 4.

[0077] It should be noted that the positioning clamp device 4 can be used to position and clamp a certain part between the two ends of the product 6, such as the middle position, to prevent the product 6 from shifting during the molding process.

[0078] S3. The product 6 is pressed by the edge pressing fixtures 53 in the two edge pressing devices 5 respectively. The first translation drive part 52 in the two edge pressing devices 5 is in transmission cooperation with the transmission structure 3 to drive the first moving plate 51 to move away from the positioning fixture device 4 along the slide rail structure 2, so as to press the edge of the product 6 in the extension direction area.

[0079] It should be noted that the edge-fitting and forming clamps 53 in the two edge-fitting and forming devices 5 clamp the adjacent left and right positions of the product 6 respectively (in other words, the edge-fitting and forming clamps 53 exert a certain squeezing or forming force on the adjacent positions of the product positioning parts). Subsequently, the first translation drive unit 52 in the two edge-fitting and forming devices 5 is in transmission cooperation with the transmission structure 3 to drive the corresponding edge-fitting and forming clamps 53 along the extension direction of the slide rail structure 2 away from the positioning clamp device 4 by driving the first moving plate 51. In other words, the two edge-fitting and forming clamps 53 move from the adjacent positions of the positioning clamp device 4 to both ends of the product 6. Since the two edge-fitting and forming clamps 53 always exert a stable squeezing or forming force on the product 6 during the movement, the edge-fitting and forming operation is realized in the extension direction area of ​​the product 6. When the two ends of the product 6 are detached from the two edge-fitting and forming clamps 53, the forming operation of the product 6 is completed.

[0080] S4. The two edge-fitting clamps 53 release the product 6, and the positioning clamp device 4 releases the product 6.

[0081] It should be noted that after the edge-fitting and molding operation of product 6 is completed, the two edge-fitting and molding clamps 53 release product 6, and the positioning clamp device 4 releases product 6, thereby releasing the two edge-fitting and molding clamps 53 and the positioning clamp device 4 from fixing product 6, so that the workers can take out the molded product 6 and prepare for the feeding process of the next product 6 to be molded.

[0082] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
