Description

Technical Field

[0001] This invention relates to the field of automated mesh implantation technology, specifically to a mesh fabric external forming mechanism. Background Technology

[0002] In injection molding production, some products require the insertion of unusual materials, such as mesh, nylon, and steel wire, to improve strength and tensile strength. Mesh is the most commonly used. For products with embedded mesh, the mesh may have a unique structure, requiring irregular shapes, such as arcs or angled sections. The conventional method for embedding mesh in such products involves first cutting the mesh into a straight line, then inserting it flat into the mold. The mold then uses suction to hold the mesh in place, and finally, the internal mechanism of the mold folds the mesh into the desired shape during mold closing. However, because the forming surface of the mold is arc-shaped with limited contact area, this method makes it difficult to embed the mesh in a specific position. Therefore, the success rate of mesh embedding is low, making production difficult and significantly impacting delivery time. Summary of the Invention

[0003] The purpose of this invention is to provide a wire mesh external forming mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a network cabling external forming mechanism, comprising a carrier plate, a first mounting hole provided at the lower left end of the carrier plate, two mounting support holes connected above the first mounting hole, the two mounting support holes being symmetrically arranged front and back and penetrating the carrier plate upwards, a support insert provided in the first mounting hole, the support insert comprising an insert body and a support protrusion, the insert body being disposed in the first mounting hole, the two support protrusions being symmetrically arranged above the insert body, the two support protrusions being respectively disposed in the two mounting support holes, a contoured boss provided on the carrier plate, the contoured boss being located in the middle of the two support protrusions, a second mounting hole penetrating vertically on each of the two support protrusions, the second mounting hole communicating with the first mounting hole, a spring installed in each of the two second mounting holes, a cover plate covering the first mounting hole provided at the lower end of the carrier plate, a contoured suction block mounted above the support insert, a bent pipe joint provided at the right end of the carrier plate, and a negative pressure air inlet connecting the bent pipe joint and the first mounting hole provided on the carrier plate.

[0005] In a further preferred embodiment, the contoured protrusion is provided with a first air passage hole that runs vertically through it, and the insert body is provided with a second air passage hole that connects to the first air passage hole. The second air passage hole is connected to the first mounting hole, so that the contoured protrusion has an adsorption force and can adsorb the mesh fabric.

[0006] Further preferably, an auxiliary hole is provided on the right side of the insert body. The auxiliary hole connects to the second mounting hole and the second air passage hole. By setting the auxiliary hole, the communication area between the second mounting hole and the second air passage hole and the first mounting hole is increased, the air passage surface is increased, and the adsorption capacity of the support insert and the contoured boss on the mesh is improved.

[0007] Further preferably, the carrier plate has a through-hole in the middle for installing a connecting shaft, thereby enabling the installation and fixing of the carrier plate; the carrier plate has two symmetrically arranged second fixing holes on its upper part, both of which are connected to the connecting hole. The second fixing holes are used for installing bolts, thereby reinforcing the installation of the connecting shaft.

[0008] Further preferably, the lower right end of the contouring suction block is provided with a contouring surface, which is an upwardly concave arc-shaped surface, so as to press the mesh into an arc-shaped structure.

[0009] Further preferably, the contoured surface is provided with at least two air suction holes, through which the mesh fabric is adsorbed; the contoured suction block is connected to a moving mechanism to realize the movement of the contoured suction block, which facilitates the contoured suction block to press down on the mesh fabric and to move the mesh fabric away.

[0010] Further preferably, the second mounting hole is a stepped hole, with the lower diameter of the second mounting hole being larger than the upper diameter, thereby limiting the installation of the spring.

[0011] Further preferably, the cover plate is provided with two positioning holes for matching springs. The positioning holes are blind holes used to position the lower end of the spring to prevent the spring from tilting or moving. The outer diameter of the spring matches the lower diameter of the second mounting hole and the diameter of the positioning hole to ensure that the spring will not move arbitrarily and to ensure that the movement direction of the support insert is consistent. The spring is a miniature spring with high stability and is not easy to bend, ensuring smooth lifting and lowering of the support insert.

[0012] Further preferably, the cover plate is provided with two third mounting holes, and fastening screws are connected in the third mounting holes. The carrier plate is provided with two first fixing holes that cooperate with the fastening screws. Through the third mounting holes and the first fixing holes, the fastening screws fix the cover plate to the bottom of the carrier plate.

[0013] Further preferably, the carrier plate has clearance grooves on both the upper and lower sides of the left end, which facilitates the installation of the cover plate and prevents it from affecting the downward pressing and forming operation of the contour suction plate; the bent pipe joint is connected to a negative pressure suction device, which can generate negative pressure to realize the adsorption of the mesh by the forming mechanism.

[0014] Beneficial effects: The mesh fabric external forming mechanism disclosed in this invention, through the support insert and the contour suction block, allows the support protrusion to move up and down under the action of a spring, forming support for the mesh fabric. Combined with the stationary contour suction block, the mesh fabric is pushed into the contour surface of the arc-shaped contour suction block, achieving automatic external forming of the mesh fabric and effectively ensuring the forming quality of the mesh fabric. This forming mechanism has a simple structure, is easy to maintain, and facilitates easy and efficient mesh fabric forming, achieving rapid external forming of the mesh fabric. It can also effectively reduce the production cost of the mesh fabric and the manufacturing cost of the equipment. Through external forming of the mesh fabric, the difficulty of inserting the mesh fabric into the mold can be reduced, ensuring the stability and quality of the mesh fabric during mold insertion, and improving the yield and production efficiency of the final product.

Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1-7 As shown, an external forming mechanism for mesh fabric is used to form mesh fabric separately outside the fabric. This forming structure allows the mesh fabric to be folded into the desired arc shape. The forming mechanism includes a carrier plate 1 for mounting the mesh fabric forming components. A first mounting hole 11 is provided at the lower left end of the carrier plate 1. Two mounting support holes 18 are connected above the first mounting hole 11, symmetrically arranged front and rear and extending upwards through the carrier plate 1. A support insert 2 is provided inside the first mounting hole 11, which supports the mesh fabric and facilitates its forming.

[0027] The support insert 2 includes an insert body 21 and support protrusions 22. The insert body 21 is disposed within the first mounting hole 11. Two support protrusions 22 are symmetrically arranged above the insert body 21, and each protrusion passes through a mounting hole 18. A contoured boss 12 is provided on the carrier plate 1, located between the two support protrusions 22. Each support protrusion 22 has a second mounting hole 23 that extends vertically through it, communicating with the first mounting hole 11. A spring 5 is installed in each of the two second mounting holes 23. The boss 12 adopts a contoured structure. Two supporting protrusions 22, in conjunction with the contoured boss 12, provide support for the placement and forming of the mesh fabric. The spring 5 enables the support insert 2 to rise and fall, descending under pressure while simultaneously generating an upward force. Under the force of the spring 5, the supporting protrusions 22 support the mesh fabric, holding its bottom surface during forming and preventing excessive deformation that could affect the forming quality. The spring 5 also allows the supporting insert 2 to move and reset, facilitating continuous operation of the forming mechanism. The two second mounting holes 23 not only limit the movement of the spring 5 but also serve as gas flow channels. Negative pressure is used to adsorb the mesh fabric, fixing it to the top of the supporting protrusions 22 for easy forming. The first mounting hole accommodates the insert body 21 and the spring 5 and connects to the negative pressure inlet 13. The negative pressure generated in the negative pressure inlet 13 creates negative pressure in the second mounting holes 23. A cover plate 4 is provided below the carrier plate 1. The cover plate 4 seals the first mounting hole 11 to prevent air leakage, so that a sealed cavity space can be formed inside the first mounting hole 11 to ensure the adsorption effect of negative pressure on the mesh fabric, and at the same time, it can support the spring 5. A contouring suction block 3 is mounted above the support insert 2. The contouring suction block 3 is connected to a moving mechanism, which can be a servo linear module or a robotic arm. It can drive the contouring suction block 3 to move. By pressing down on the support protrusion 22, the support protrusion 22 can be moved towards the spring 5. The contouring boss 12 between the two support protrusions 22 is fixed to the carrier plate 1 and will not move. As the contouring suction block 3 is pressed down, the contouring boss 12 and the two support protrusions 22 form a state of one high and two low, so that the mesh fabric part on the contouring boss 12 and the two support protrusions 22 enters the contouring surface 31 of the contouring suction block 5. The contouring surface 31 is an upwardly concave arc surface. The middle height of the mesh fabric remains unchanged. The two ends of the mesh fabric bend downward as the support protrusion 22 is pressed down, thereby realizing the structure of pressing the mesh fabric into an arc shape and realizing the forming of the mesh fabric.

[0028] In this application, the right end of the carrier plate 1 is provided with a bent pipe joint 7 for connecting a negative pressure suction device, which can generate negative pressure and achieve adsorption of the mesh fabric through the negative pressure air inlet 13 of the first mounting hole 11 provided on the carrier plate 1, so as to ensure that the mesh fabric can be adsorbed on the support protrusion 22.

[0029] In this application, the contoured boss 12 is provided with a first air passage 14 that runs vertically through it, and the insert body 21 is provided with a second air passage 24 that connects to the first air passage 14. The second air passage 24 is connected to the first mounting hole 11. By setting the first air passage 14 and the second air passage 24, a negative pressure can be formed on the end face of the contoured boss 12 to adsorb the mesh fabric, further strengthening the adsorption force on the mesh fabric, ensuring that the mesh fabric will not move during forming, and improving the forming quality of the mesh fabric.

[0030] In this application, an auxiliary hole 25 is provided on the right side of the insert body 21. The auxiliary hole 25 is connected to the second mounting hole 23 and the second air passage hole 24. By setting the auxiliary hole 25, the gas flow channel can be increased, the influence of the spring 5 on the second mounting hole 23 can be reduced, and the adsorption force on the mesh cloth can be improved.

[0031] In this application, the carrier plate 1 has a through-hole 15 in the middle, and two symmetrically arranged second fixing holes 17 on the top of the carrier plate 1, both of which are connected to the through-hole 15. The through-hole 15 is used to install a connecting shaft, providing support for the carrier plate 1 and facilitating adjustment of its position and angle. The two second fixing holes 17 are screw holes for installing bolts, securing the connecting shaft installed in the through-hole 15, and improving the installation stability of the carrier plate 1.

[0032] In this application, the contoured surface 31 is provided with at least two suction holes 32, which can adsorb the formed mesh fabric and facilitate the removal of the formed mesh fabric. This application uses three suction holes 32, which are evenly arranged along the arc surface of the contoured surface 31 to ensure effective adsorption of the mesh fabric.

[0033] In this application, the cover plate 4 is provided with two positioning holes 41 that cooperate with the spring 5. The positioning holes 41 are blind holes to position the spring 5 and prevent the spring 5 from being skewed, which would cause the direction of the spring 5's contraction and extension to tilt, affecting the movement and reset of the support insert 2. The outer diameter of the spring 5 matches the lower end diameter of the second mounting hole 23 and the diameter of the positioning hole, ensuring that the spring 5 will not move arbitrarily. As the spring 5 contracts and extends, it ensures that the direction of movement of the support insert 2 is consistent. The spring 5 is a miniature spring with high stability and is not easy to bend, ensuring smooth lifting and lowering of the support insert 2 and effectively ensuring the forming quality of the mesh.

[0034] In this application, the cover plate 4 is provided with two third mounting holes 42, and fastening screws 6 are connected in the third mounting holes 42. The carrier plate 1 is provided with two first fixing holes 16 that cooperate with the fastening screws 6. Among them, the third mounting holes 42 are smooth holes, and the first fixing holes 16 are screw holes, used to connect with the fastening screws 6, so as to fix the cover plate 4 under the carrier plate 1.

[0035] In this application, the second mounting hole 23 is a stepped hole, and the lower end diameter of the second mounting hole 23 is larger than the upper end diameter, so as to limit the spring 5, ensure that the spring 5 can generate an upward force on the support insert 2, and ensure the support insert 2 supports the mesh and the support insert 2 resets after the mesh is formed.

[0036] In this application, clearance grooves are provided on both the upper and lower sides of the left end of the carrier plate 1. The clearance groove on the lower side of the carrier plate 1 facilitates the installation of the cover plate 4, and the clearance groove on the upper side of the carrier plate 1 facilitates the forming operation of the mesh and prevents it from affecting the downward pressure of the contour suction block 3.

[0037] In this application, the working process of the forming mechanism is as follows: During operation, the automatic machine cuts the mesh fabric into a straight shape, such as... Figure 8 As shown, this is the structure of a mesh fabric cut by an automatic machine. The mesh fabric is transported to two support protrusions 22 and a contouring boss 12 via a conveying mechanism. Negative pressure generated by a negative pressure suction device is applied through the bent pipe connector 7, negative pressure air inlet 13, first mounting hole 11, second mounting hole 12, second air outlet 24, and first air outlet 14 to adhere the mesh fabric. The contouring suction block 3, under the action of the moving mechanism, reaches above the mesh fabric and then presses it down. The two support protrusions 22 move downwards under the action of the contouring suction block 3 and spring 5, while the contouring boss 12 remains stationary and continues to press against the mesh fabric, thus pressing the mesh fabric onto the contouring surface 31 of the contouring suction block 3, pressing the straight mesh fabric into an arc shape, completing the mesh fabric forming process. Figure 9 The diagram shows the structure of the formed mesh. After the mesh is formed, the suction holes 32 on the contour suction block 3 generate suction on the mesh, adsorbing it and moving it to the next workstation via a moving mechanism.
