[0002] The existing mesh laminating technology cannot well fix the mesh on the surface of hemispherical products or spherical products. Many people pull a large area of ​​mesh and wrap it on the surface of hemispherical products or spherical products. The tensile force required for the mesh cannot be stably controlled. Too much tension will cause the mesh to crack. Too little tension or uneven force on the mesh will cause the mesh to wrinkle and the laminating effect is poor. When the product is transferred to the next process, the manual movement of the staff may cause the product to come apart. This may lead to poor production quality and low first-time yield of the product, requiring more people to rework and repair, further reducing work efficiency. Summary of the invention

[0004] Further, the first vertical driving mechanism includes a first cylinder, the first cylinder is provided with a first push rod, the first push rod is slidably connected to the first cylinder, the second vertical driving mechanism includes a second cylinder and a push plate, the second cylinder is provided with a second push rod, the second push rod is slidably connected to the second cylinder, the push plate is provided with a gap for the carrier fixing plate to pass through, and the positioning fixture can be connected to the push plate.

Some hemispherical products need to be provided with soft buttons on the surface. During the stretching and laminating process of the mesh cloth, the soft buttons will be concave due to the squeezing force generated by the mesh cloth, thereby causing the mesh cloth to deform on the arc surface. Therefore, it is necessary to use the button support mechanism to support the soft buttons from the inside of the hemispherical product during the stretching of the mesh cloth and the hot pressing process. The inclined cylinder is fixed to the connecting plate so that the inclined cylinder can always be stationary relative to the push plate and the transport carrier connected to the push plate during the movement of the push plate, so as to achieve the support work for the soft buttons inside the hemispherical product during the stretching of the mesh cloth and the hot pressing process.

[0007] Furthermore, the pressing plate and the bottom plate are both polygonal structures, and a limiting boss is provided on the edge of the bottom plate, and the limiting boss is used to quickly position the pressing plate on the bottom plate. The combination of the polygonal structure and the limiting boss facilitates positioning while ensuring that the relative position of the pressing plate and the bottom plate does not shift, thereby avoiding the circular holes of the pressing plate and the bottom plate not being able to overlap due to the relative position shift between the pressing plate and the bottom plate, thereby affecting the mesh lamination effect of the hemispherical product.

[0008] Furthermore, the pressing plate and the bottom plate are both provided with magnets, and the magnets are distributed in a circular array at the edge of the circular hole and evenly distributed at the pressing plate and other positions of the pressing plate except the edge of the circular hole.

The magnets are installed in a circular array at the edge of the circular hole to ensure that the mesh in the circular hole part is always kept taut. The magnets are installed at other positions of the pressing plate and the bottom plate except the edge of the circular hole to ensure that the mesh part except the circular hole is evenly stressed without wrinkles. During the bonding process of the hemispherical product, the various parts of the mesh can move synchronously toward the circular hole part, which can effectively avoid wrinkles after the hemispherical product is bonded.

An external clamping mechanism such as a manipulator can transfer the base plate and the positioning fixture respectively by applying force to the first blocking plate and the third blocking plate, which is easy to realize automation. The first blocking plate and the third blocking plate fixed by screws or positioning pins are easy to replace. When the blocking plate is damaged due to long-term force, it can be replaced by removing the screws, and the blocking plate of different materials can also be replaced according to the force conditions.

[0010] Furthermore, a placing base is provided at the lower end of the placing sphere, and a second blocking plate for contacting an external force-applying object is provided at the upper end of the placing base, and the second blocking plate is fixed to the placing sphere by a latch. An external clamping mechanism such as a manipulator can move the placing sphere by applying force to the second blocking plate, which is easy to realize automation. The second blocking plate fixed by the latch is easy to replace. When the blocking plate is damaged due to long-term force, it can be replaced by removing the latch, and the blocking plate of different materials can also be replaced according to the force conditions.

[0011] Furthermore, the positioning jig is positioned on the push plate by means of matching positioning pins and pin holes, and the positioning jig is connected to the top of the push plate by means of magnets; the placement base is positioned on the positioning jig by means of matching positioning pins and pin holes, and the placement base is connected to the top of the positioning jig by means of magnets; the bottom plate is positioned on the positioning jig by means of matching positioning pins and pin holes, and the bottom plate is connected to the positioning jig by means of magnets; the bottom plate is positioned on the carrier fixing plate by means of matching positioning pins and pin holes, and the bottom plate is connected to the carrier fixing plate by means of magnets.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0026] Figure 1-Figure 7 The present invention shows a mesh stretching and laminating device for hemispherical products, comprising a frame 1, wherein the frame 1 comprises an upper support plate 11 and a lower support plate 12, wherein the upper support plate 11 is fixed to the lower support plate 12 via a plurality of support columns 113, and further comprises a first vertical drive mechanism 2, a hot pressing jig 3 and a transfer carrier 4; the first vertical drive mechanism 2 is fixed to the top of the upper support plate 11; the transfer carrier 4 comprises a mesh clamping jig 41, a product placement jig 42 and a positioning jig 43, wherein the mesh clamping jig 41 comprises a pressing plate 411 and a bottom plate 421 connected via a magnet 6, wherein the middle portions of the pressing plate 411 and the bottom plate 421 are provided with a circular hole through which the product placement jig 42 can penetrate; the product placement jig 42 comprises a placement sphere 421, wherein the outer surface of the placement sphere 421 is connected to the placement sphere 421 so as to match the inner surface of the hemispherical product 8 to be processed. The hot pressing jig 3 includes an upper mold 31 and a lower mold 32, the upper mold 31 includes a hot pressing mechanism 311 and a heat insulation board 312, the hot pressing mechanism 311 is fixed to the heat insulation board 312, the heat insulation board 312 is fixed to the first vertical driving mechanism 2, the first vertical driving mechanism 2 can drive the hot pressing mechanism 311 to make a linear motion in the vertical direction, the lower surface of the hot pressing mechanism 311 is provided with a hemispherical groove 3111 which matches the outer surface of the hemispherical product 8 to be processed, the lower mold 32 of the hot pressing jig is provided with a plurality of carrier fixing plates 321 for supporting the mesh clamping jig 41 and a second vertical driving mechanism 322 for making the transfer carrier 4 make a vertical upward linear motion, and the plurality of carrier fixing plates 321 are fixed to the lower support plate 12.

[0027] The first vertical driving mechanism 2 includes a first cylinder 21, the first cylinder 21 is provided with a first push rod 22, and the first push rod 22 is slidably connected to the first cylinder 21. The second vertical driving mechanism 322 includes a second cylinder 3221 and a push plate 3223. The second cylinder 3221 is provided with a second push rod 3222, and the second push rod 3222 is slidably connected to the second cylinder 3221. The push plate 3223 is provided with a gap for the carrier fixing plate 321 to pass through, and the positioning fixture 43 can be connected to the push plate 3223.

[0028] It includes a button support mechanism 5, which includes an inclined cylinder 51. The push plate 3223 is provided with a connecting plate 511. The inclined cylinder 51 is fixed to the connecting plate 511. The inclined cylinder 51 is provided with an inclined push rod 52. One end of the inclined push rod 52 is provided with a supporting arc 521 for supporting the soft buttons on the surface of the hemispherical product 8. The placement sphere 421 is provided with a gap for the inclined push rod to pass through. The inclined cylinder 51 and the inclined push rod 52 are inclined at an angle to the horizontal plane. Some hemispherical products 8 need to be provided with soft buttons on their surfaces. During the mesh stretching and bonding process, the soft buttons will be sunken due to the extrusion force generated by the mesh, thereby causing arc deformation of the mesh. Therefore, it is necessary to use the button support mechanism 5 to support the soft buttons from the inside of the hemispherical product 8 during the mesh stretching and hot pressing process. The inclined cylinder 51 is fixed to the connecting plate 511 so that the push plate 3223 can always be stationary relative to the push plate 3223 and the transfer carrier 4 connected to the push plate 3223 during the movement, thereby achieving support for the soft buttons inside the hemispherical product 8 during the mesh stretching and hot pressing process.

[0029] A heating tube 3112 is provided inside the hot pressing mechanism 311, and a thermocouple 3113 is provided in the hot pressing mechanism 311. The material of the working surface of the hot pressing mechanism 311 is polytetrafluoroethylene. Polytetrafluoroethylene has the characteristics of high temperature resistance, corrosion resistance, non-stickiness, and extremely low friction coefficient, which prevents impurities such as dust from sticking or the mesh 413 from sticking to the working surface during the stretching and bonding process, thereby affecting the mesh bonding effect of the hemispherical product, and further improves the mesh bonding quality of the hemispherical product 8.

[0030] The pressing plate 411 and the bottom plate 421 are both polygonal structures, and a limiting boss 4121 is provided on the edge of the bottom plate 421, and the limiting boss 4121 is used to quickly position the pressing plate 411 on the bottom plate 421. The combination of the polygonal structure and the limiting boss 4121 facilitates positioning while ensuring that the relative position of the pressing plate 411 and the bottom plate 421 does not shift, thereby preventing the circular holes of the pressing plate 411 and the bottom plate 421 from not overlapping due to the relative position shift of the pressing plate 411 and the bottom plate 421, thereby affecting the mesh bonding effect of the hemispherical product 8.

[0031] The pressing plate 411 and the bottom plate 421 are both provided with magnets 6 , which are distributed in a circular array at the edge of the circular hole and evenly distributed at the pressing plate 411 and other positions of the pressing plate 411 except the edge of the circular hole. Different meshes 413 require different clamping forces for bonding. The magnetic force between the pressing plate 411 and the bottom plate 421 can be changed by changing the number and size of the installed magnets 6 to avoid the mesh 413 from cracking due to excessive magnetic force or wrinkling due to insufficient magnetic force, thereby improving the effect of bonding the mesh 413 to the hemispherical product 8. The magnets 6 are installed in a circular array at the edge of the circular hole to ensure that the mesh 413 in the circular hole part is always kept taut. Magnets 6 are installed at other positions of the pressing plate 411 and the bottom plate 421 except the edge of the circular hole to ensure that the mesh 413 other than the circular hole is evenly stressed without wrinkles. During the bonding process of the hemispherical product 8, various parts of the mesh 413 can move toward the circular hole part synchronously, which can effectively avoid wrinkles after the hemispherical product 8 is bonded.

[0032] The bottom plate 421 is provided with a first blocking plate 4122 for contacting an external force-applying object, and the side of the positioning fixture 43 is provided with a third blocking plate 4321 for contacting an external force-applying object, and the first blocking plate 4122 and the third blocking plate 4321 are respectively fixed to the edges of the bottom plate 421 and the positioning fixture 43 by screws or positioning pins 7. An external clamping mechanism such as a manipulator can apply force to the first blocking plate 4122 and the third blocking plate 4321 to transfer the bottom plate 421 and the positioning fixture 43 respectively, which is easy to realize automation. The first blocking plate 4122 and the third blocking plate 4321 fixed by screws or positioning pins 7 are easy to replace. When the blocking plate is damaged due to long-term force, it can be replaced by removing the screws, and blocking plates of different materials can also be replaced according to the force conditions.

[0033] The lower end of the placement sphere 421 is provided with a placement base 422, and the upper end of the placement base 422 is provided with a second blocking plate 4221 for contacting an external force-applying object, and the second blocking plate 4221 is fixed to the placement sphere 421 by a latch. An external clamping mechanism such as a manipulator can move the placement sphere 421 by applying a force to the second blocking plate 4221, which is easy to realize automation. The second blocking plate 4221 fixed by the latch is easy to replace. When the blocking plate is damaged due to long-term force, it can be replaced by removing the latch, and the blocking plate of different materials can also be replaced according to the force conditions.

[0034] The positioning jig 43 is positioned on the push plate 3223 by means of matching positioning pins 7 and pin holes, and the positioning jig 43 is connected to the top of the push plate 3223 by means of magnets 6; the placement base 422 is positioned on the positioning jig 43 by means of matching positioning pins 7 and pin holes, and the placement base 422 is connected to the top of the positioning jig 43 by means of magnets 6; the bottom plate 421 is positioned on the positioning jig 43 by means of matching positioning pins 7 and pin holes, and the bottom plate 421 is connected to the positioning jig 43 by means of magnets 6. The relative positions of the positioning jig 43 and the base plate 421, the positioning jig 43 and the placement base 422, and the positioning jig 43 and the push plate 3223 are accurately positioned by slidingly cooperating with the positioning pin 7 and the pin hole. The magnetic connection is easy to connect and separate, which improves the work efficiency while ensuring that the relative positions of the positioning jig 43 and the base plate 421, the positioning jig 43 and the placement base 422, and the positioning jig 43 and the push plate 3223 are not offset, thereby improving the mesh bonding effect.

[0035] Working method: Step (1): The staff places the mesh 413 on the upper surface of the bottom plate 421, and places the pressing plate 411 above the mesh 413. Under the action of the magnetic force, the mesh 413 is clamped. If the relative position of the pressing plate 411 and the bottom plate 421 is offset, the pressing plate 411 cannot be placed horizontally above the bottom plate 421 due to the protrusion of the limiting boss 4121. At this time, the staff slightly moves the pressing plate 411 so that the pressing plate 411 is placed horizontally above the bottom plate 421. The setting of the limiting boss 4121 ensures that the relative position of the pressing plate 411 and the bottom plate 421 is not offset, and it is also more convenient for the staff to realize the positioning of the pressing plate 411.

[0036] Step (2): Install the hemispherical product 8 in a wrapped manner on the placement sphere 421, apply pressure to the third blocking plate 4321 through an external clamping mechanism such as a manipulator and move the product placement jig 42, so that the product placement jig 42 is installed on the positioning jig 43; apply pressure to the third blocking plate 4321 through an external clamping mechanism such as a manipulator and move the positioning jig 43, so that the positioning jig 43 is fixed to the upper end of the push plate 3223, apply pressure to the first blocking plate 4122 through an external clamping mechanism such as a manipulator and move the mesh clamping jig 41, so that the mesh clamping jig 41 is fixed to the upper end of the carrier fixing plate 321, and the upper surface of the push plate 3223 is located directly below the upper surface of the carrier fixing plate 321;

[0037] Step (3): the second cylinder 3221 pushes the positioning fixture 43 equipped with the sphere 421 to make a vertical upward movement through the second push rod 3222, and the hemispherical product 8 makes a vertical upward movement relative to the mesh clamping fixture 41, and the hemispherical product 8 lifts up the mesh 413, and the part of the mesh 413 located between the pressing plate 411 and the bottom plate 421 gradually moves to the circular hole in the middle, and the mesh 413 gradually wraps the hemispherical product 8. At the same time, the first cylinder 21 pushes the hot pressing mechanism 311 to make a vertical downward movement through the first push rod 22, completing the stretching, wrapping and hot pressing of the mesh 413 of the hemispherical product 8, that is, completing the bonding work of the mesh 413 of the hemispherical product 8, and the bottom plate 421 is bonded with the positioning fixture 43. At this time, the mesh clamping fixture 41, the sphere 421 and the positioning fixture 43 form an integrated transfer carrier 4;

[0038] Step (4): Apply pressure to the third baffle plate 4321 through an external clamping mechanism such as a robot arm and move the integrated transfer carrier 4 to the next process.

[0039] The beneficial effects of the present invention are as follows: the mesh clamping fixture 41 places the mesh 413 between the pressing plate 411 and the bottom plate 421 connected by the magnet 6, and the mesh 413 can be clamped, and there is no need for multiple people to stretch the mesh 413, which improves work efficiency and avoids the uneven stretching force of the staff and the uncontrollability of manual force, and more stably controls the stretching force required for the mesh 413, thereby improving the fitting effect of the mesh 413; the product placement fixture 42 can be connected to the top of the positioning fixture 43, and is installed on the push plate 3 through an external clamping mechanism such as a manipulator, a first vertical drive mechanism 2 and a carrier fixing plate 321. The product placement jig 42 on the positioning jig 43 of 223 moves vertically upward relative to the mesh clamping jig 41, and at the same time, the hot pressing mechanism 311 presses down on the hemispherical product 8 installed on the placement sphere 421, thereby completing the stretching and hot pressing bonding of the mesh 413 of the hemispherical product 8. After completing the stretching and bonding of the mesh 413, the mesh clamping jig 41 will be installed on the positioning jig 43. The integrated transfer carrier 4 can be transferred to the next process by means of clamping by an external clamping mechanism such as a robot, etc., to avoid the problem of product debonding that may occur during manual movement, and further improve the mesh bonding effect and work efficiency.
