Description

Technical Field

[0001] The invention mainly relates to the field of SMC ceiling processing technology, in particular to a SMC antibacterial ceiling forming device and a continuous forming process. Background Art

[0002] SMC material is a glass fiber reinforced plastic made of unsaturated polyester resin, glass fiber roving, and other matching materials, which is then thickened, cut, put into a metal mold and cured at high temperature and high pressure. SMC material has high strength and rigidity. Its tensile strength, bending strength and impact strength are comparable to those of some metal materials. It can meet the requirements of structural strength under different working conditions. At the same time, it is light in weight, with a specific gravity between 1.7-2.0, which can achieve lightweight design. On the premise of excellent mechanical strength, SMC material has good tolerance to acids, alkalis, salts, organic solvents, etc., can maintain stable performance for a long time in harsh chemical environments, and also has excellent electrical insulation properties and thermal stability.

[0003] Based on the above advantages, SMC materials are widely used in the fields of industry, construction, communications, etc. Based on its excellent physical and chemical properties, in interior design, SMC wall panels and ceilings are usually added with silver ion antibacterial additives. Based on this, SMC ceilings usually have antibacterial properties, so compared with ordinary ceilings, they are more popular. Especially in public places such as shopping malls, hospitals, and stations, SMC antibacterial ceilings are widely used due to their own fire retardant, waterproof and moisture-proof, stain-resistant and easy to clean, thermal insulation, antibacterial and antibacterial characteristics. Whether used in public places or residential areas, they have advantages that traditional ceilings cannot match.

[0004] The molding of the antibacterial ceiling made of SMC material is different from the various special-shaped shell parts used in industry. The material of the ceiling has a standard shape and uniform thickness, which makes it easier to distribute and fill when hot pressing and melting. This makes it unnecessary to deliberately distribute the fillers when feeding the raw material sheets into the mold. And because its thickness is generally small, the molding time is short. Based on this molding feature, it is easier to apply mechanized operations in the molding process of SMC ceilings.

[0005] The current problems in processing are the low degree of mechanization. The manual weighing and feeding method seriously restricts production efficiency. Although the molding machine is more efficient in the production of ceilings, it still takes 3-5 minutes. This leads to the inability to achieve optimal coordination between manual work and the molding machine, which seriously affects the improvement of production efficiency. Summary of the invention

[0036] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application. Example

[0037] The present invention provides an SMC antibacterial ceiling forming device, which realizes the automated production of SMC ceilings. The cutting, weighing, and loading and unloading of the sheet no longer require manual operation, and the process is clearer and more specific. One cutting and weighing unit corresponds to multiple forming units, which greatly improves the production efficiency. The device as a whole includes a continuously arranged sheet cutting machine, a front conveyor belt, a weighing platform 2, and multiple forming machines 3. A front manipulator 4 for transferring the cut sheet from the front conveyor belt to the weighing platform 2 is arranged on one side of the front conveyor belt and the weighing platform 2. The sheet cutting machine realizes automated feeding, film tearing, and cutting of the sheet. The cut sheet is transported away from the sheet cutting machine by the front conveyor belt, and then transported to the grabbing position, where it is grabbed by the front manipulator 4 and accurately transported to the weighing platform 2 for weighing. The front robot 4 completes the grabbing and releasing actions of the sheet. In order not to interfere with the feeding and grabbing and feeding actions after weighing is completed, the present invention designs the front robot 4 into a cantilever structure. The front robot 4 is only installed on one side to avoid interference with subsequent actions.

[0038] The specific structure of the front manipulator 4 is as follows: it includes a front frame 41 arranged on one side of the front conveyor belt and the weighing platform 2, and the front frame 41 is fixedly installed on the ground by expansion bolts to ensure stable support and ensure the accuracy of sheet material grabbing and transportation. The front frame 41 is horizontally installed with a front slide rail 42 and a front screw drive mechanism 43 along the conveying direction of the front conveyor belt. The front drive seat 44 is slidably arranged on the front slide rail 42. The front screw drive mechanism 43 is driven by a servo motor. The front drive seat 44 is fixedly installed on the synchronous belt. Through the drive of the front screw drive mechanism 43, the front drive seat 44 can be driven to slide accurately along the front slide rail 42. The front conveyor belt conveys the cut sheets, and the conveying position of the sheets is positioned by the position sensor installed on its edge. The front drive seat 44 is accurately parked at the position to be grabbed of the sheets through the servo drive, thereby completing the determination of the grabbing position. The front drive seat 44 is installed with a lifting rail 45 and a lifting screw drive mechanism 46. The lifting screw drive mechanism 46 includes a lifting screw and a screw motor. The lifting screw is rotatably installed between the two lifting rails 45. The cantilever frame 47 is slidably installed on the lifting rail 45. The lifting screw cooperates with the screw nut installed at the end of the cantilever frame 47. The screw motor adopts a servo motor. The cantilever frame 47 can be driven to lift accurately and stably through the drive of the screw motor. The cantilever rail 48 and the cantilever synchronous belt drive mechanism 49 are installed on the cantilever frame 47. The front grabbing suction cup 40 is slidably set on the cantilever rail 48. The front grabbing suction cup 40 includes a suction cup frame and a plurality of negative pressure suction cups. The suction cup frame is slidably installed on the cantilever rail 48. The cantilever synchronous belt drive mechanism 49 is driven by a servo motor, which can drive the front grabbing suction cup 40 to accurately and stably dock at any position of the cantilever frame 47. The cantilever synchronous belt drive mechanism 49 is used to drive the front grabbing suction cup 40 to move in the width direction of the front conveyor belt to achieve left and right adjustment of the grabbing position. The synchronous belt mechanism is lighter in weight and can achieve a weight reduction effect when applied to the cantilever structure. The lifting screw drive mechanism 46 controls the up and down movement of the cantilever frame 47, thereby completing the grabbing and releasing of the sheet. The front manipulator 4 adopts a cantilever structure to achieve displacement in three-dimensional space and realize automatic positioning, grabbing and positioning release of the sheet. No human intervention is required in the process, making the cutting and weighing of the sheet more standardized and normalized, and the operation time of each process can be quantified, so that it can cope with the continuous molding operations of multiple molding machines and improve the overall processing efficiency.

[0039] Since there are thickness errors in the sheet material during the preparation process, and there may be wrinkles and edge defects, the weight of the sheets cut at a fixed width may not meet the standard after being stacked. In the prior art, manual cutting and replenishing is usually adopted, but the present invention focuses on the automated production process, and the manual material distribution method cannot meet the design requirements. Therefore, the present invention adds an automatic material distribution device, which can automatically replenish the sheet material according to the weighing data of the weighing table 2 to ensure that the quality of the sheet material raw material meets the standard, ensure sufficient flow under high temperature and high pressure during molding by the molding machine 3, and ensure the quality of the finished product.

[0040] Specifically, the feeding mechanism 1 is arranged on the other side of the weighing platform 2 to avoid interference with the front manipulator 4. The feeding mechanism 1 includes a feeding frame 11, on which a feeding arm 13 is rotatably arranged, and the feeding arm 13 can swing in a horizontal plane. A swing drive mechanism 14 is arranged at the bottom of the feeding frame 11, and the swing drive mechanism 14 is used to drive the feeding arm 13 to swing. The swing drive mechanism 14 is a combination of a servo motor and a gear reducer. Through the drive of the swing drive mechanism 14, the feeding arm 13 can be driven to swing above the sheet to be weighed or to one side of the weighing platform 2. Through the design of the swinging action, the feeding arm 13 can be swung to the top of the weighing platform 2 for feeding when feeding is needed. When feeding is not needed, the feeding arm 13 is on standby on one side and does not interfere with the front manipulator 4. A material tray 12 is rotatably installed on the rear side of the feeding arm 13, and the material tray 12 is used to store and release the sheet for feeding. Specifically, the sheet material for replenishment is formed by continuously cutting the whole box of sheet material with a cutting machine, and the sheet material is rolled up by a material tray while cutting, and is used as a standby for replenishment. The material tray 12 is driven by a rotating motor, and the release of the sheet material for replenishment is achieved by the rotation of the motor.

[0041] The sheet material on the feed tray 12 passes through the feeding arm 13 and is released at the front end of the feeding arm 13. The feeding arm 13 serves as a channel for the feeding sheet material, so that it can be smoothly released onto the stacked complete sheets to complete the weight replenishment. The feeding arm 13 is equipped with several pairs of conveying rollers 16, at least one of which is an active roller. The active roller is driven by a servo motor, thereby driving the conveyed sheet material to be transported stably. A meter is connected to one of the driven rollers to count the conveying length of the sheet material. The weight of the sheet material can be calculated by the length of the sheet material, thereby more accurately controlling the weight of the feeding. A pneumatic shear 15 is arranged at the front end of the feeding arm 13, and the pneumatic shear 15 is used to cut the feeding sheet material, thereby completing the release of the feeding sheet material. Furthermore, in order to ensure the stable transportation of the filling sheet, the present invention sets a pair of compression conveyor belts 17 in an upper and lower position relationship on the front side of the filling arm 13, and the filling sheet passes between the two compression conveyor belts 17, and the pneumatic shears 15 are installed on the front side of the pair of compression conveyor belts 17. Each compression conveyor belt 17 includes a pair of compression rollers arranged front and back, and at least one compression roller is an active roller driven by a driving motor. A compression belt is stretched between the two compression rollers, and the two compression belts rotate in opposite directions. The distance between the upper and lower compression belts is less than the thickness of the sheet. The sheet is squeezed and conveyed by the two compression conveyor belts 17. This conveying structure can further reduce the sliding between the sheet and the conveying roller 16, thereby ensuring the weight of the filling sheet.

[0042] The plurality of molding machines 3 are arranged linearly, and preferably, the spacing between two adjacent molding machines 3 is consistent. The molding machine 3 is equipped with an upper mold and a lower mold, and heating oil is passed through the mold to complete heating. The upper mold is pushed down by a hydraulic cylinder to press the sheet between the upper mold and the lower mold, and the melting and shaping of the sheet are completed by high temperature and high pressure.

[0043] A feeding slide rail 58 is laid between the molding machine 3 and the weighing platform 2, and the feeding slide rail 58 is parallel to the arrangement direction of the molding machine 3. A feeding screw drive mechanism 59 is arranged on one side of the feeding slide rail 58. In this embodiment, the feeding slide rail 58 is a pair of parallelly arranged, and the feeding screw drive mechanism 59 is arranged between the two feeding slide rails 58. The feeding screw drive mechanism 59 includes a rotatably mounted feeding cylinder, and the end of the feeding screw is driven by a servo motor. A transfer seat 5 is slidably arranged on the feeding slide rail 58, and a screw nut matched with the feeding screw is installed at the bottom of the transfer seat 5. Driven by the feeding screw drive mechanism 59, the transfer seat 5 can be driven to run accurately and stably along the feeding slide rail 58, so that the transfer seat 5 can be more accurately docked at a position corresponding to the molding machine 3.

[0044] A loading positioning mechanism 52 corresponding to the molding machine 3 is installed on the loading slide rail 58. The loading positioning mechanism 52 is used to position the displacement of the transfer seat 5, so that the transfer seat 5 can be accurately docked at the molding machine 3 to complete the loading operation of the sheet raw materials. Specifically, a loading manipulator 51 is installed on the transfer seat 5. The loading manipulator 51 adopts a four-axis or five-axis mechanical arm. The front end of the mechanical arm is equipped with a needle mechanism to grab the stacked sheets, and follow the transfer seat 5 to transfer to the corresponding position of the molding machine 3. Finally, the loading manipulator 51 completes the automatic feeding of the sheets. The feeding positioning mechanism 52 in the present invention is used to position the feeding point of the transfer seat 5, and specifically includes a feeding positioning sensor and a feeding positioning cylinder 54. A feeding positioning plate is set at the front end of the piston rod of the feeding positioning cylinder 54. When the feeding positioning cylinder 54 is in a retracted state, the feeding positioning plate will not interfere with the feeding slide 58. Only when the corresponding molding machine 3 completes the processing of the previous product and is about to carry out the next feeding, the feeding positioning cylinder 54 extends, and the feeding positioning plate is located on the feeding slide 58 to block the transfer seat 5. The feeding positioning sensor is installed on the feeding slide 58 to assist in positioning, and the feeding positioning cylinder 54 is used as a mechanical positioning component. The two cooperate to achieve accurate positioning of the feeding position, ensuring the accuracy of the feeding action of the feeding manipulator 51.

[0045] The molding machine 3 is used to heat and pressurize the raw material sheet so that the sheet is melted and spread in the mold, and a chemical reaction occurs under high temperature and high pressure to finally shape it. After the SMC ceiling is shaped, an automated pickup device is also used to automatically pick up the ceiling sheet, avoiding direct contact between workers and high-temperature sheets. At the same time, the pickup can be completed in time, improving the overall processing efficiency. Specifically, a discharge slide 56 parallel to the loading slide 58 is laid on the rear side of the molding machine 3, and a discharge screw drive mechanism 57 is set on one side of the discharge slide 56. Specifically, the discharge slide 56 has the same laying structure as the loading slide 58, and also adopts a double-track structure, and the discharge screw drive mechanism 57 is set between the two discharge slides 56. The discharge screw drive mechanism 57 includes a discharge screw rotatably installed between the two discharge slides 56, and the end of the discharge screw is driven by a servo motor. The pick-up seat 6 is slidably mounted on the unloading slide rail 56, and a screw nut matching the unloading screw is mounted at the bottom of the pick-up seat 6. The unloading screw drive mechanism 57 drives the pick-up seat 6 to slide accurately along the unloading slide rail 56, so that the pick-up seat 6 can be more accurately parked at the corresponding molding machine 3 to complete the subsequent grabbing of the finished ceiling product.

[0046] The unloading slide rail 56 is provided with an unloading positioning mechanism 53 corresponding to the molding machine 3. The unloading positioning mechanism 53 is used to position the displacement of the pickup seat 6, so that the pickup seat 6 can accurately stop at the molding machine 3 to complete the pickup operation of the finished ceiling parts. Specifically, the unloading manipulator 61 is installed on the pickup seat 6. The unloading manipulator 61 and the loading manipulator 51 can use the same model of four-axis or five-axis manipulator. The front end of the manipulator is equipped with a negative pressure suction cup group to grab the processed ceiling and transfer the ceiling to the rear conveyor belt to the next finishing process. The unloading positioning mechanism 53 of the present invention is used to position the pickup point of the pickup seat 6, and specifically includes an unloading positioning sensor and an unloading positioning cylinder 55. The front end of the piston rod of the unloading positioning cylinder 55 is provided with an unloading positioning plate. When the unloading positioning cylinder 55 is in a retracted state, the unloading positioning plate will not interfere with the unloading slide rail 56. Only when the corresponding molding machine 3 completes the processing of the finished ceiling product, the unloading positioning cylinder 55 extends, and the unloading positioning plate is located on the unloading slide rail 56 to block the pickup seat 6. The unloading positioning sensor is installed on the unloading slide rail 56 to assist in positioning, and the unloading positioning cylinder 55 is used as a mechanical positioning component. The two cooperate to achieve accurate positioning of the pickup position, ensuring that the unloading manipulator 61 accurately grabs the finished ceiling product.

[0047] In view of the above SMC antibacterial ceiling molding equipment, a SMC antibacterial ceiling continuous molding process is provided. The main steps are as follows:

[0048] The continuous sheets are cut by a sheet cutting machine, the sheets are automatically conveyed on the sheet cutting machine, and the film tearing operation is completed. The width of the conveyed sheets is adjustable, and finally the fixed width cutting of the sheets is completed by the reciprocating motion of the cutting knife of the sheet cutting machine.

[0049] The cut sheets are transported to the grabbing point by the front conveyor belt, and the front manipulator 4 grabs the sheets and transfers them to the weighing platform 2. Depending on the thickness of the SMC ceiling being processed, the sheets are stacked in 2-4 layers on the weighing platform 2, and the stacked sheets are weighed on the weighing platform 2. If the weight m after weighing is y If the weight after weighing is less than the standard weight m, the feeding mechanism 1 will automatically feed the material to make the total weight greater than or equal to m. y If the weight is not less than the standard weight m, it is directly grabbed by the feeding robot 51 and transferred to the molding machine 3 for hot pressing molding.

[0050] Among them, when the feeding mechanism 1 is feeding, the feeding arm 13 first swings to the top of the stacked sheets, and at the same time, the feeding sheet is released through the material tray 12, and the conveying roller 16 drives the sheet to be conveyed on the feeding arm 13. After the conveyed sheet is of sufficient length, the sheet is cut by the pneumatic shears 15 so that it falls on the stacked sheets to complete the feeding, and then the feeding arm 13 is reset.

[0051] Specifically, in order to ensure that the weight of the sheet material after feeding can meet the standard, no secondary feeding is performed. The present invention adopts an excessive feeding method to meet the total weight of the sheet material. The weight after weighing m y The difference from the standard weight m is m n , the feeding weight of feeding mechanism 1 is m b , then m b is m n In this embodiment, the SMC ceiling is 600×600mm and 2.0mm thick, with an area of ​​0.36 square meters and a density of 1.8 g / cm³, so the weight is about 130g. n When it is less than or equal to 0.5g, m b is m n 4 times, when the difference m n When greater than 0.5g and less than or equal to 1g, m b is m n 2 times, when the difference m n When greater than 1g and less than or equal to 2g, m b is m n 1.5 times of the difference m n When it is greater than 2g, m b is m n This feeding method can ensure that the sheet material reaches the standard weight after feeding to the greatest extent, and reduce the waste of sheet material to a certain extent.

[0052] The weighed sheets are transferred to the molding machine 3 for hot pressing and shaping. Multiple molding machines 3 receive the sheets in sequence according to the arrangement order. The sheets cover 70%-80% of the area of ​​the lower mold of the molding machine 3. The mold temperature of the molding machine 3 is 130-150 degrees, the molding pressure is 6-8 MPa, and the holding time is 3-5 minutes, so that the SMC ceiling is hot pressed in the mold.

[0053] The finished ceiling product is taken out of the molding machine 3 by the unloading robot and transported to the next process by the rear conveyor belt for trimming of waste edges and grinding of mold edges.

[0054] In this embodiment, each cutting and weighing device corresponds to 3-5 forming machines 3, which fully improves the utilization rate of the cutting and weighing devices, wherein the cutting and weighing devices correspond to the middle position of multiple forming machines 3. Example

[0055] In response to the solution of Example 1, a preheating device is added in this embodiment before the sheet raw material is transferred from the weighing platform 2 to the molding machine 3. The preheating device preheats the sheet raw material. The preheating device adopts an electric heating structure, which can accurately control the temperature. Compared with the heating oil heating method of the mold, the heating speed is faster, thereby shortening the time for the raw material to be heated from room temperature to a molten state, so that each molding process of the molding machine is shortened by about 20 seconds, thereby improving the overall processing efficiency.

[0056] Specifically, a central conveyor belt 7 is arranged between the weighing platform 2 and the feeding slide rail 58. The central conveyor belt 7 is arranged downstream of the weighing platform 2 and does not contact the weighing platform 2. The weighing conveyor belt is on the top of the weighing platform 2. The weighing conveyor belt does not move during the weighing process to avoid interference with the weighing result. After the weighing is qualified, the weighing conveyor belt starts to drive the sheet raw material to the central conveyor belt 7 to complete the delivery of the sheet raw material. A heating bin 8 is arranged above the middle of the central conveyor belt 7. The central conveyor belt 7 is used to transport the weighed sheet raw material to the end to be grabbed by the feeding robot 51. During the conveying process, the sheet raw material is paused or runs slowly in the heating bin 8, and the sheet raw material is preheated by the heating bin 8, and the preheating temperature is 75-80 degrees. A temperature sensor is installed in the heating bin 8 to control the heating temperature of the sheet raw material.
