[0002] The existing mesh laminating technology cannot well fix the mesh on the surface of hemispherical or spherical products. Many people pull a large area of ​​mesh and wrap it on the surface of hemispherical 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. After the product has completed the stretching and laminating of the mesh, when it enters the process of cutting and folding the remaining fabric, 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

When the flanging portion works, it is flush with the lower end surface of the hemispherical product. The sum of the lengths of the flanging portions of all the sliders is greater than the circumference of the hemispherical product; a heating pipe and a thermocouple are provided inside the slider.;

[0004] Further, there are six sliders.

The fifth cylinder pushes the slider through the fifth push rod; the flanging fitting device includes an upper die of the flanging device.

[0006] Further, the cutting device includes a second rotating motor, a turntable, and a laser cutting gun. The second rotating motor is fixed to the workbench. The second rotating motor is connected to the turntable through a rotating shaft. The transfer carrier can be connected to the turntable. The laser cutting gun is connected to the workbench through a fixing bracket. The nozzle of the laser cutting gun is aligned with the outer diameter position of the hemispherical product connected to the turntable to cut the excess fabric of the hemispherical product.

[0007] Further, the clamping device includes a middle component and clamping components respectively arranged at both ends of the middle component. The middle component is provided with a third motor. The clamping components are matched with the third motor through a screw rod. The third motor can drive the screw rod to move horizontally through rotation, so as to control the tightness of the clamping components. By adopting the transmission mode of driving the screw rod by the rotation of the motor and controlling the third motor to control the tightness effect of the clamping device, the structure is simple, easy to realize automation, and improves work efficiency.

[0008] Further, it includes a key support mechanism. The key support mechanism includes an inclined cylinder. The second push plate is provided with a connecting plate. The inclined cylinder is fixed to the connecting plate. The inclined cylinder is provided with an inclined push rod. One end of the inclined push rod is provided with a supporting arc for supporting the soft key on the surface of the hemispherical product. The placing sphere is provided with a gap through which the inclined push rod can pass through. The inclined cylinder and the inclined push rod have an inclined angle with the horizontal plane. Soft keys need to be set on the surface of some hemispherical products. During the stretching and fitting process of the mesh fabric, the soft key part will be sunken due to the extrusion force generated by the mesh fabric, resulting in arc surface deformation of the mesh fabric. Therefore, it is necessary to use the key support mechanism to support the soft key part from the inside of the hemispherical product during the stretching of the mesh fabric and the hot pressing process. Fix the inclined cylinder to the connecting plate, so that the inclined cylinder can always be stationary relative to the push plate and the transfer carrier connected to the second push plate during the movement of the second push plate, realizing the support work for the soft key part inside the hemispherical product during the stretching of the mesh fabric and the hot pressing process.

[0009] Furthermore, both the pressing plate and the bottom plate are of polygonal structures. A limiting boss is provided at the edge of the bottom plate, and the limiting boss is used to quickly position the pressing plate on the bottom plate. Magnets are provided on both the pressing plate and the bottom plate. The magnets are arranged in a circumferential array at the edge of the circular hole and are evenly distributed at other positions of the pressing plate and the bottom plate except the edge of the circular hole. The combination of the polygonal structure and the limiting boss facilitates positioning while ensuring that the relative positions of the pressing plate and the bottom plate do not shift, avoiding the situation where the circular holes of the pressing plate and the bottom plate cannot coincide due to the relative position shift between the pressing plate and the bottom plate, which affects the mesh cloth fitting effect of the hemispherical product. Different clamping forces are required for the fitting of the mesh cloth. The magnetic force between the pressing plate and the bottom plate can be changed by changing the number and size of the installed magnets, avoiding the mesh cloth from bursting due to excessive magnetic force and avoiding the mesh cloth from wrinkling due to too small magnetic force, thereby improving the mesh cloth fitting effect for the hemispherical product. The magnets are arranged in a circumferential array at the edge of the circular hole, which can ensure that the mesh cloth at the circular hole part always remains in a taut state. Installing magnets at other positions of the pressing plate and the bottom plate except the edge of the circular hole can ensure that the part of the mesh cloth except the circular hole is evenly stressed without generating wrinkles. During the cloth pasting process of the hemispherical product, each part of the mesh cloth can move synchronously towards the circular hole part, effectively avoiding wrinkles after the cloth is pasted on the hemispherical product.

[0010] Furthermore, the bottom plate is provided with a first barrier for contacting the clamping component, and the side of the positioning jig is provided with a third barrier for contacting the clamping component. A placing base is provided at the lower end of the placing sphere, and a second barrier for contacting the clamping component is provided at the upper end of the placing base. The first barrier, the second barrier, and the third barrier are respectively fixed to the edges of the bottom plate, the placing sphere, and the positioning jig by screws or positioning pins. The clamping device can move the bottom plate, the product placing jig, and the positioning jig respectively by applying forces to the first barrier, the second barrier, and the third barrier, which is easy to realize automation. When the barrier is damaged due to long-term stress, it can be replaced by removing the relevant screws or positioning pins, or different materials of the barrier can be replaced according to the stress situation.

[0011] Further, the positioning fixture is positioned on the second push plate through a cooperating positioning pin and pin hole, and the positioning fixture is connected above the second push plate by a magnet; the placement base is positioned on the positioning fixture through a cooperating positioning pin and pin hole, and the placement base is connected above the positioning fixture by a magnet; the bottom plate is positioned on the positioning fixture through a cooperating positioning pin and pin hole, and the bottom plate is connected to the positioning fixture by a magnet; the bottom plate is positioned on the carrier fixing plate through a cooperating positioning pin and pin hole, and the bottom plate is connected to the carrier fixing plate by a magnet; the placement base is positioned on the middle die core through a cooperating positioning pin and pin hole, and the placement base is connected above the middle die core by a magnet; the positioning fixture is positioned on the turntable through a cooperating positioning pin and pin hole, and the positioning fixture is connected to the surface of the turntable by a magnet. The precise positioning of the relative positions of the relevant connecting components is achieved by the sliding fit of the positioning pin and the pin hole. By means of magnetic connection, it is easy to connect and separate, improving the work efficiency while ensuring that the relative positions of the relevant components do not shift, thereby further improving the mesh cloth fitting effect.

[0012] The present invention provides a method for stretching and folding the mesh cloth for a hemispherical product. A method for fitting the mesh cloth to the hemispherical product by using the above-mentioned mesh cloth fitting device for the hemispherical product is as follows:

[0013] Step (1): The worker places the mesh cloth on the upper surface of the bottom plate and places the pressing plate above the mesh cloth. Under the action of magnetic force, the mesh cloth is clamped. If the relative position between the pressing plate and the bottom plate shifts, the pressing plate cannot be horizontally placed above the bottom plate due to the protrusion of the limiting boss. At this time, the worker slightly moves the pressing plate to make the pressing plate horizontally placed above the bottom plate.

[0014] Step (2): The hemispherical product to be processed with glue on its surface is wrapped and installed on the placement sphere. The clamping device applies pressure to the second partition plate and moves the product placement fixture, thereby installing the product placement fixture on the positioning fixture; the clamping device applies pressure to the third partition plate and moves the positioning fixture, thereby fixing the positioning fixture to the upper end of the second push plate; the clamping device applies pressure to the first partition plate and moves the mesh cloth clamping fixture, thereby fixing the mesh cloth clamping fixture to the carrier fixing plate, and the upper surface of the second push plate is located directly below the upper surface of the carrier fixing plate.

[0015] Step (3): The second cylinder drives the positioning fixture with the sphere placed thereon to move vertically upward through the second push rod. The hemispherical product moves vertically upward relative to the mesh clamping fixture. The hemispherical product lifts the mesh, and the part of the mesh located between the pressing plate and the bottom plate gradually moves to the circular hole in the middle. The mesh gradually wraps the hemispherical product. At the same time, the first cylinder drives the hot pressing mechanism to move vertically downward through the first push rod, completing the stretching and wrapping of the mesh on the hemispherical product and the hot pressing and fitting, that is, completing the mesh stretching and fitting work on the hemispherical product. The bottom plate is in contact with the positioning fixture. At this time, the mesh clamping fixture, the sphere placement, and the positioning fixture form an integrated transfer carrier.

[0016] Step (4): Apply pressure to the third partition board through the clamping device to clamp it, and move the integrated transfer carrier. Connect the positioning fixture to the turntable. The first rotation motor drives the turntable to rotate, thereby rotating the transfer carrier. The laser cutting gun performs laser on a point position in the outer diameter of the hemispherical product. As the transfer carrier rotates, the excess mesh outside the outer diameter of the hemispherical product is initially cut.

[0017] Step (5): Apply pressure to the third partition board through the clamping device to clamp it, and move the integrated transfer carrier. Connect the positioning fixture to the middle die core. Initially, control the third vertical driving mechanism to lower the fitting movable die core fixed to the third push plate, so that the fitting movable die core is below the middle die core. Control the fourth vertical driving mechanism to press the upper die core against the hemispherical product. The three small sliders slide inward to iron and push the fabric. After maintaining pressure for a period of time, the three groups of small sliders retract. Then the three large sliders slide inward to iron and push the fabric. After maintaining pressure for a period of time, the three large sliders retract. The third vertical driving mechanism drives the fitting movable die core to push upward, and the fitting movable die core squeezes the fabric to fit the inner side of the hemispherical product. After the pressure maintaining is completed, the fourth vertical driving mechanism drives the upper die core to rise. Finally, the clamping device takes out the product, completing the hemming and fitting work.

[0018] The beneficial effects produced by the present invention are as follows: The mesh cloth clamping fixture places the mesh cloth between the pressing plate and the bottom plate connected by magnets, and the mesh cloth can be clamped. There is no need for multiple people to stretch the mesh cloth, which improves work efficiency. It can also avoid uneven stretching force of the staff and the uncontrollability of manual force application, more stably control the stretching force required for the mesh cloth, and improve the fitting effect of the mesh cloth. The product placement fixture can be connected above the positioning fixture. Through the clamping device, the second vertical driving mechanism and the carrier fixing plate, the product placement fixture installed on the positioning fixture of the second push plate moves vertically upward relative to the mesh cloth clamping fixture. At the same time, the hot pressing mechanism presses down on the hemispherical product with the placed sphere, thereby completing the mesh cloth stretching and hot pressing fitting work for the hemispherical product. After completing the mesh cloth stretching and fitting work, the mesh cloth clamping fixture will be installed on the positioning fixture. The integrated transfer carrier can be transferred to the cutting device through the clamping device, avoiding the problem of possible product glue opening during manual handling, further improving the mesh cloth fitting effect and work efficiency. After cutting the excess mesh cloth, the integrated transfer carrier can be transferred to the hemming and fitting device through the clamping device. The sum of the lengths of the hemming parts of all the sliders is greater than the circumference of the hemispherical product, ensuring that all the mesh cloth outside the edge of the hemispherical product can be folded into the hemispherical product, ensuring the hemming and fitting efficiency. The hot pressing mechanism is adopted to avoid the condensation of the glue on the product surface, further ensuring the fitting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] It includes a key support mechanism 3323. The key support mechanism 3323 includes an inclined cylinder 33231. The second push plate 33222 is provided with a connecting plate 33232. The inclined cylinder 33231 is fixed to the connecting plate 33232. The inclined cylinder 33231 is provided with an inclined push rod 33233.

The placing sphere 221 is provided with a gap through which the inclined push rod 33233 can pass. The inclined cylinder 33231 and the inclined push rod 33233 are inclined with respect to the horizontal plane. Soft keys need to be provided on the surface of some hemispherical products 6. During the stretching and fitting process of the mesh cloth, the soft key part will be sunken due to the extrusion force generated by the mesh cloth 9, resulting in arc surface deformation of the mesh cloth 9. Therefore, during the stretching of the mesh cloth and the hot pressing process, it is necessary to use the key support mechanism 3323 to support the soft key part from the inside of the hemispherical product 6. The inclined cylinder 33231 is fixed to the connecting plate 33232, so that the inclined cylinder 33231 can always be stationary relative to the second push plate 33222 and the transfer carrier 2 connected to the second push plate 33222 during the movement of the push plate, realizing the support work for the soft key part inside the hemispherical product during the stretching of the mesh cloth 9 and the hot pressing process.

[0045] Both the pressing plate 211 and the bottom plate 212 are hexagonal structures. The edge of the bottom plate 212 is provided with a limiting boss 2121 for quickly positioning the pressing plate 211 on the bottom plate 212. Both the pressing plate 211 and the bottom plate 212 are provided with magnets 7. The magnets 7 are arranged in a circular array at the edge of the round hole and evenly distributed at other positions of the pressing plate 211 and the pressing plate 211 except the edge of the round hole. The combination of the polygonal structure and the limiting boss 2121 facilitates positioning while ensuring that the relative positions of the pressing plate 211 and the bottom plate 212 do not shift, avoiding the non - coincidence of the round holes of the pressing plate 211 and the bottom plate 212 due to the relative position shift of the pressing plate 211 and the bottom plate 212, which affects the fitting effect of the mesh cloth 9 on the hemispherical product 6. Different clamping forces are required for the fitting of the mesh cloth 9. The magnetic force between the pressing plate 211 and the bottom plate 212 can be changed by changing the installation quantity and size of the magnets 7, avoiding the cracking of the mesh cloth 9 caused by excessive magnetic force and the wrinkling of the mesh cloth 9 caused by too small magnetic force, thereby improving the fitting effect of the mesh cloth 9 on the hemispherical product 6. The magnets 7 are arranged in a circular array at the edge of the round hole, which can ensure that the mesh cloth 9 at the round hole part always remains taut. Installing the magnets 7 at other positions of the pressing plate 211 and the bottom plate 212 except the edge of the round hole can ensure that the part of the mesh cloth 9 except the round hole is evenly stressed without generating wrinkles. During the cloth - pasting process of the hemispherical product 6, each part of the mesh cloth 9 can move synchronously towards the round hole part, effectively avoiding the generation of wrinkles after the hemispherical product 6 is pasted with the cloth.

[0046] The bottom plate 212 is provided with a first partition plate 2122 for contacting and clamping the component 1142. The side surface of the positioning jig 23 is provided with a third partition plate 231 for contacting and clamping the component 1142.

The first partition plate 2122, the second partition plate 22111 and the third partition plate 231 are respectively fixed to the edges of the bottom plate 212, the sphere placing part 221 and the positioning jig 23 by screws or positioning pins 8. The clamping device 114 can move the bottom plate 212, the product placing jig 22 and the positioning jig 23 by applying forces to the first partition plate 2122, the second partition plate 22111 and the third partition plate 231 respectively, which is easy to realize automation. When the partition plate is damaged due to long-term stress, it can be replaced by removing the relevant screws or positioning pins 8, or different materials of partition plates can be replaced according to the stress situation.

[0047] The positioning jig 23 is positioned on the second push plate 33222 through the matching positioning pin 8 and pin hole, and the positioning jig 23 is connected above the second push plate 33222 by a magnet 7. The placing base 2211 is positioned on the positioning jig 23 through the matching positioning pin 8 and pin hole, and the placing base 2211 is connected above the positioning jig 23 by a magnet 7. The bottom plate 212 is positioned on the positioning jig 23 through the matching positioning pin 8 and pin hole, and the bottom plate 212 is connected to the positioning jig 23 by a magnet 7. The bottom plate 212 is positioned on the carrier fixing plate 3321 through the matching positioning pin 8 and pin hole, and the bottom plate 212 is connected to the carrier fixing plate 3321 by a magnet 7. The placing base 2211 is positioned on the middle die core 513 through the matching positioning pin 8 and pin hole, and the placing base 2211 is connected above the middle die core 513 by a magnet 7. The positioning jig 23 is positioned on the turntable 42 through the matching positioning pin 8 and pin hole, and the positioning jig 23 is connected to the surface of the turntable 42 by a magnet 7. The precise positioning of the relative positions of the relevant connecting components is realized by the sliding fit of the positioning pin 8 and the pin hole. By the magnetic connection method, it is easy to connect and separate, improving the working efficiency while ensuring that the relative positions of the relevant components do not shift, thus further improving the mesh cloth laminating effect.

[0048] The present invention provides a method for stretching and laminating and hemming and laminating a mesh cloth 9 for a hemispherical product 6. A method for laminating a mesh cloth for a hemispherical product 6 by using the above-mentioned mesh cloth laminating device for a hemispherical product 6 is as follows:

[0049] Step (1): The staff places the mesh cloth 9 on the upper surface of the bottom plate 212 and places the pressing plate 211 above the mesh cloth 9. Under the action of magnetic force, the mesh cloth 9 is clamped. If the relative position of the pressing plate 211 and the bottom plate 212 is offset, the pressing plate 211 cannot be horizontally placed above the bottom plate 212 due to the protrusion of the limit boss 2121. At this time, the staff slightly moves the pressing plate 211 to make the pressing plate 211 horizontally placed above the bottom plate 212;

[0050] Step (2): The hemispherical product 6 to be processed with glue on its surface is installed in a wrapped manner on the placement sphere 221. The clamping device 114 applies pressure to the second partition plate 22111 and moves the product placement jig 22, so as to install the product placement jig 22 on the positioning jig 23; the clamping device 114 applies pressure to the third partition plate 231 and moves the positioning jig 23, so as to fix the positioning jig 23 to the upper end of the second push plate 33222; the clamping device 114 applies pressure to the first partition plate 2122 and moves the mesh cloth clamping jig 21, so as to fix the mesh cloth clamping jig 21 to the carrier fixing plate 3321. The upper surface of the second push plate 33222 is located directly below the upper surface of the carrier fixing plate 3321;

[0051] Step (3): The second cylinder 33221 drives the positioning jig 23 equipped with the placement sphere 221 to move vertically upward through the second push rod 33223. The hemispherical product 6 moves vertically upward relative to the mesh cloth clamping jig 21. The hemispherical product 6 lifts the mesh cloth 9, and the part of the mesh cloth 9 located between the pressing plate 211 and the bottom plate 212 gradually moves to the middle circular hole. The mesh cloth 9 gradually wraps the hemispherical product 6. At the same time, the first cylinder 321 drives the hot pressing mechanism 3311 to move vertically downward through the first push rod 322, completing the stretching and wrapping and hot pressing and fitting of the mesh cloth 9 on the hemispherical product 6, that is, completing the stretching and fitting work of the mesh cloth 9 on the hemispherical product 6. The bottom plate 212 is attached to the positioning jig 23. At this time, the mesh cloth clamping jig 21, the placement sphere 221 and the positioning jig 23 form an integrated transfer carrier 2;

[0052] Step (4): The clamping device 114 applies pressure to the third partition plate 231 for clamping, and moves the integrated transfer carrier 2 to connect the positioning jig 23 to the turntable 42. The first rotation motor 115 drives the turntable 42 to rotate, thereby rotating the transfer carrier 2. The laser cutting gun 43 performs laser on a point position in the outer diameter of the hemispherical product 6. As the transfer carrier 2 rotates, the excess mesh cloth 9 outside the outer diameter of the hemispherical product 6 is preliminarily cut;

[0053] Step (5): Apply pressure to the third partition plate 231 through the clamping device 114 to clamp it, and move the integrated transfer carrier 2 to connect the positioning jig 23 to the middle die core 513. Initially, control the third vertical driving mechanism 512 to lower the fitting movable die core 514 fixed to the third push plate 5123, so that the fitting movable die core 514 is located below the middle die core 513. Control the fourth vertical driving mechanism 522 to press the upper die core 523 against the hemispherical product 6. The three small sliders 5112 slide inward to iron and push the fabric. After maintaining pressure for a period of time, the three small sliders 5112 retract. Then, the three large sliders 5111 slide inward to iron and push the fabric. After maintaining pressure for a period of time, the three large sliders 5111 retract. The third vertical driving mechanism 512 drives the fitting movable die core 514 to push upward, and the fitting movable die core 514 presses the fabric against the inner side of the hemispherical product 6. After the pressure maintaining is completed, the fourth vertical driving mechanism 522 drives the upper die core 523 to rise. Finally, the clamping device 114 takes out the product to complete the hemming and fitting work.

[0054] The beneficial effects of the present invention are as follows: The mesh clamping jig places the mesh between the pressing plate and the bottom plate connected by magnets, and the mesh can be clamped, eliminating the need for multiple people to stretch the mesh, improving work efficiency, and avoiding uneven stretching force and uncontrollability of manual force application by workers. It can more stably control the stretching force required for the mesh and improve the mesh fitting effect. The product placement jig can be connected above the positioning jig. Through the clamping device, the second vertical driving mechanism, and the carrier fixing plate, the product placement jig installed on the second push plate moves vertically upward relative to the mesh clamping jig, while the hot pressing mechanism presses the hemispherical product installed with the placement sphere, thereby completing the mesh stretching and hot pressing fitting work for the hemispherical product. After completing the mesh stretching and fitting work, the mesh clamping jig will be installed on the positioning jig, and the integrated transfer carrier can be transferred to the cutting device through the clamping device, avoiding the problem of possible product glue opening during manual handling, further improving the mesh fitting effect and work efficiency. After cutting the excess mesh, the integrated transfer carrier can be transferred to the hemming and fitting device through the clamping device. The sum of the lengths of the hemming parts of all the sliders is greater than the circumference of the hemispherical product, ensuring that all the mesh outside the edge of the hemispherical product can be folded into the hemispherical product, ensuring the hemming and fitting efficiency. The hot pressing mechanism is adopted to avoid the condensation of the glue on the product surface, further ensuring the fitting effect.

Under the action of magnetic force, the mesh fabric is clamped. If the relative position of the pressing plate and the bottom plate is offset, the pressing plate cannot be horizontally placed above the bottom plate due to the protrusion of the limiting boss. At this time, the worker slightly moves the pressing plate to make the pressing plate horizontally placed above the bottom plate. Step (2): The hemispherical product to be processed with glue applied on its surface is installed in a wrapped manner on the sphere placement. The clamping device applies pressure to the second partition board and moves the product placement fixture, thereby installing the product placement fixture on the positioning fixture.
