Description

Technical Field

[0001] The present invention relates to the technical field of rubber transfer control, and in particular to a control method and system applied to a rubber transfer molding machine. Background Art

[0002] Rubber transfer refers to a rubber molding process that involves the use of molds. This process involves the design and manufacture of molds, as well as the molding process of rubber products. The rubber transfer molding machine is used to make rubber products through the rubber transfer process. Specifically, the rubber transfer molding machine heats and pressurizes the rubber through the mold to shape it in the mold, thereby obtaining the desired rubber product. This process is often used to produce various rubber products, such as seals, gaskets, pipe connectors, etc.

[0003] The most important factors affecting the rubber molding effect in the rubber transfer process are the temperature, pressure and time during transfer. If the transfer temperature is low or the transfer time is short, the rubber cannot be effectively melted, resulting in the product not being formed. If the transfer pressure is small, the rubber cannot be fully filled, resulting in bubbles in the product. However, traditional rubber transfer molding machines are manually controlled and automatically controlled. Manual control requires manual pressing by staff, and the production efficiency is low and cannot be mass-produced; while automatic control can only produce according to preset transfer parameters, and cannot automatically adjust the transfer parameters according to the product, resulting in a low yield rate. Therefore, it is necessary to design a control method and system for rubber transfer molding machines to solve the problem of low efficiency of traditional manual transfer and low yield rate of automatic transfer. Summary of the invention

[0004] In view of this, the present invention proposes a control method and system for a rubber transfer molding machine, aiming to solve the problem of low efficiency of traditional manual transfer and low yield of automatic transfer.

[0005] In one aspect, the present invention provides a control method and system for a rubber injection molding machine, comprising:

[0006] Turn on the machine and install the product mold into the transfer mechanism;

[0007] Click the Start option on the control panel, select the type of rubber compound used, then click Start Quality Inspection, select the automatic mode and confirm, and the rubber transfer molding machine will start the quality test;

[0008] The detection module obtains product information by detecting the product mold, and transmits the information to the data processing module and the information storage module. The data processing module generates the transfer temperature parameter, the transfer pressure parameter, the transfer time parameter, and the required rubber material quality parameter, and transmits the parameter information to the control module;

[0009] After receiving the information, the control module controls the mold moving mechanism to feed the rubber material into the mold, and then moves the remaining rubber material back to its original position;

[0010] The mold closes and the injection starts. The control module controls the injection mechanism to increase the mold temperature and pressure to the set parameter values;

[0011] When the preset time is reached, heating and pressurization stop, and the injection ends. The control module controls the cooling system to rapidly cool the mold;

[0012] When the detection module detects that the mold has cooled to the set temperature, the cooling ends. The control module controls the injection mechanism to open the mold, and controls the ejection mechanism to eject the rubber product;

[0013] The quality inspection module inspects whether the product is qualified. If the inspection is qualified, the injection parameters of the product are stored in the information storage module, and then the production quantity is set. The injection machine starts automatic production until the corresponding quantity of products is produced. During the automatic production process, the detection module real-time detects the temperature and pressure during injection. When any one of them exceeds the preset maximum value, the control module immediately controls the rubber injection machine to stop running and issues an alarm; If it is unqualified, the quality inspection module adjusts the parameters according to the product defects, and then restarts the quality test until the test is qualified;

[0014] The information storage module presets the density ρ of various types of rubber materials. The data processing module calculates the required rubber material mass parameter M according to the product volume V and the density calculation formula M = ρ×V;

[0015] The quality inspection module determines whether the product is qualified by detecting three defect parameters: the smoothness of the product surface, whether there are bubbles in the product, and the product quality error. If one or more of the three defect parameters are unqualified, the product is unqualified.

[0016] Furthermore, the information storage module sets the required injection temperature and injection pressure for various types of rubber materials. The data processing module generates injection temperature parameters and injection pressure parameters according to the selected rubber material type.

[0017] Furthermore, the detection module obtains the mold volume V by detecting the product mold. The data processing module pre-sets a first preset time T1, a second preset time T2, a third preset time T3, and a fourth preset time T4, and T1 < T2 < T3 < T4; A first product volume V1, a second product volume V2, a third product volume V3, and a fourth product volume V4 are pre-set, and VI < V2 < V3 < V4;

[0018] Determine the injection time according to the detected product volume V and the pre-set product volume size relationship:

[0019] When V1≤V<V2, the first predetermined time T1 is selected as the transfer time;

[0020] When V2≤V<V3, the second predetermined time T2 is selected as the transfer time;

[0021] When V3≤V<V4, the third predetermined time T3 is selected as the transfer time;

[0022] When V4≤V, the fourth predetermined time T4 is selected as the transfer time.

[0023] Furthermore, the quality detection module includes an image collection unit for collecting product images. The quality detection module divides the product image into a number of pixel blocks, and then obtains the overall image similarity S1 by calculating the similarity of adjacent pixel blocks, and compares the calculated similarity S1 with the similarity S preset in the quality detection module:

[0024] When S1<S, the product surface is not smooth, and then the quality inspection module increases the transfer time according to the difference ΔS between S1 and S2. The larger the difference, the larger the adjustment value.

[0025] When S1≥S, the product surface is smooth.

[0026] Furthermore, the quality detection module detects the actual volume V2 and the actual mass M1 of the product. The quality detection module obtains the product mass M2 by V2×ρ according to the formula M=ρ×V, and then compares the values ​​of M1 and M2:

[0027] When M1<M2, there are bubbles in the product, and then the quality inspection module increases the pressure parameter according to the difference ΔM between M1 and M2. The larger the difference, the larger the adjustment value.

[0028] When M1≥M2, the product contains bubbles.

[0029] Furthermore, the quality detection module compares the measured actual product quality M1 with the product quality M:

[0030] When M1<M, there is an error in product quality, and then the quality detection module increases the required rubber quality parameter according to the M difference ΔM1 of M1, and the value of ΔM1 is the increased parameter value.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: the product volume is obtained through the product mold, and then the transfer temperature parameters, transfer time parameters, transfer pressure parameters and required rubber parameters are automatically produced according to the product volume and the type of rubber, without manual input, thereby improving work efficiency and saving labor costs; whether the product is qualified is judged by detecting three defect parameters, namely, the smoothness of the product surface, whether the product has bubbles, and the product quality error. If the product is unqualified, the transfer parameters are automatically adjusted according to the above defect parameters, thereby greatly improving the yield rate of automated production and saving production costs; by setting an information storage module to store product transfer parameter information, the information is automatically retrieved when the product is produced again, without the need to re-detect production, thereby greatly improving automated production efficiency; by providing the option of manual control for quality testing, the practicality of the rubber injection molding machine is improved.

[0032] On the other hand, the present application also provides a control system for a rubber injection molding machine, comprising:

[0033] The detection module is used to collect product mold volume information and monitor the temperature and pressure during the transfer process in real time;

[0034] A data processing module is used to generate transfer temperature parameters, transfer pressure parameters, transfer time parameters, and required rubber material quality parameters according to the product mold volume information collected by the detection module;

[0035] A control module, used for controlling the rubber transfer molding machine to produce products according to the transfer temperature parameters, transfer pressure parameters, transfer time parameters, and required rubber material quality parameters generated by the data processing module;

[0036] The quality inspection module is used to check whether the product is qualified and adjust the injection pressure parameters, injection time parameters, and the required rubber quality parameters;

[0037] When one or more of the three defect parameters, namely, product surface smoothness, product bubble and product quality error, are unqualified, the product is unqualified, and then the transfer pressure parameter, transfer time parameter and required rubber material quality parameter are automatically adjusted according to the defect parameters;

[0038] The information storage module is used to store the transfer temperature of various types of rubber materials, the density of various types of rubber materials, and the product transfer parameters, which are automatically used when the product is produced again without the need for re-testing.

[0039] It is understandable that the above-mentioned control method and system applied to the rubber injection molding machine have the same beneficial effects, which will not be described in detail here.

[0040] The present invention also includes a rubber transfer molding machine using the control method and system for rubber transfer molding machine, including: a main control box, an oil tank, a frame, a base, an upper seat, an ejection mechanism, an upper mold moving mechanism, and an upper film pulling mechanism;

[0041] A control panel is provided on an outer side wall of the main control box, and an integrated circuit board is provided on an inner side wall corresponding to the control panel, and the detection module, the data processing module, the control module and the quality detection module are integrated on the integrated circuit board;

[0042] The top of the oil tank and the bottom of the main control box are fixedly connected;

[0043] The top of the frame is connected to the bottom of the oil tank;

[0044] A body is arranged above the frame, the interior of the body includes four columns, and bases are arranged outside the four columns;

[0045] The ejection mechanism is arranged on one side of the base;

[0046] The upper seat is arranged above the base and located outside the four pillars;

[0047] The upper drawing die mechanism is arranged above one side of the upper seat;

[0048] The upper mold moving mechanism is arranged on the outer side of the column.

[0049] Furthermore, the rubber transfer molding machine further comprises a transfer mechanism, which is composed of a mold frame in front of the transfer mechanism and an upper heating plate in the rear of the transfer mechanism;

[0050] The front mold frame of the transfer mechanism is located between the upper mold mechanisms;

[0051] The rear upper heating plate of the transfer mechanism is located below the front mold frame of the transfer mechanism.

[0052] Furthermore, a motor and an oil circuit board are arranged inside the main control box.

[0053] Compared with the prior art, the beneficial effect of the present invention is that: this model adopts the above control method to move the rubber into the mold during transfer injection through the upper mold structure, and moves the rubber out after the transfer injection is completed, thereby avoiding heat vulcanization of the rubber, and can be recycled for multiple times, saving rubber.

DETAILED DESCRIPTION

[0060] The exemplary embodiments disclosed in the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments disclosed in the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0061] The rubber transfer molding machine is a machine that prepares rubber products through the transfer process. It mainly prepares rubber products by heating, melting and pressurizing the rubber in the mold. The most important factors affecting the rubber molding effect in the rubber transfer process are the temperature, pressure and time during the transfer. If the transfer temperature is low or the transfer time is short, the rubber cannot be effectively melted, resulting in the product not being formed. If the transfer pressure is small, the rubber cannot be fully filled with the rubber, resulting in bubbles in the product. However, traditional rubber transfer molding machines are manually controlled and automatically controlled. Manual control requires manual pressing by staff, and the production efficiency is low and cannot be mass-produced; while automatic control can only produce according to preset transfer parameters, and cannot automatically adjust the transfer parameters according to the product, resulting in a low yield rate. Therefore, it is necessary to design a control method and system for rubber transfer molding machines to solve the problem of low efficiency of traditional manual transfer and low yield rate of automatic transfer.

[0062] Reference Figure 1 In some embodiments of the present application, an automatic control method for a rubber injection molding machine includes:

[0063] Step 1: Turn on the machine and install the product mold into the transfer mechanism;

[0064] Step 2: Click the Start option on the control panel, select the type of rubber compound used, then click the automatic mode and confirm to start the quality test;

[0065] Step 3: The detection module obtains product information by detecting the product mold, and transmits the information to the data processing module and the information storage module. The data processing module generates the transfer temperature parameter, the transfer pressure parameter, the transfer time parameter, and the required rubber material quality parameter, and transmits the parameter information to the control module;

[0066] Step 4: After receiving the information, the control module controls the mold moving mechanism to send the rubber material into the mold, and then moves the remaining rubber material back to its original position;

[0067] Step 5: The mold is closed and transfer injection begins. The control module controls the transfer injection mechanism to increase the mold temperature and pressure to the set parameter values;

[0068] Step 6: When the preset time is reached, heating and pressurization are stopped, the transfer is ended, and the control module controls the cooling system to quickly cool the mold;

[0069] Step 7: The detection module detects that the mold has cooled to the set temperature and ends cooling. The control module controls the transfer mechanism to open the mold and controls the ejection mechanism to eject the rubber product.

[0070] Step 8: The quality inspection module checks whether the product is qualified. If the inspection is qualified, the injection parameters of the product are stored in the information storage module, and then the production quantity is set, and the injection machine starts automatic production until the corresponding quantity of products is produced; if it is unqualified, the quality inspection module adjusts the parameters according to the product defects, and then starts the quality test again until the test is qualified.

[0071] Specifically, the detection module can scan the product mold through a scanning device to obtain the volume V of the product to be produced. The first preset time T1, the second preset time T2, the third preset time T3, and the fourth preset time T4 are preset in the data processing module, and T1 < T2 < T3 < T4; the first product volume V1, the second product volume V2, the third product volume V3, and the fourth product volume V4 are preset, and V1 < V2 < V3 < V4;

[0072] Determine the injection time according to the detected product volume V and the preset product volume size relationship;

[0073] When V1 ≤ V < V2, select the first predetermined time T1 as the injection time;

[0074] When V2 ≤ V < V3, select the second predetermined time T2 as the injection time;

[0075] When V3 ≤ V < V4, select the third predetermined time T3 as the injection time;

[0076] When V4 ≤ V, select the fourth predetermined time T4 as the injection time;

[0077] It can be understood that the product volume directly affects the injection time. The larger the product volume, the more rubber material is required, and the longer its melting time is, resulting in a longer injection time.

[0078] Specifically, the data processing module obtains the required rubber material mass parameter M according to the product volume V and the density calculation formula M = ρ × V.

[0079] It can be understood that the rubber material used for the injection raw material is rubber material that has been roughly processed, and there will inevitably be air bubbles in it, so the rubber material volume cannot be directly matched according to the product volume.

[0080] Specifically, the control module is connected to the power systems of the rubber injection molding machine, such as the electrical box, fuel tank, motor, and oil circuit board; the control module controls the operation of each mechanism by controlling the power systems of the rubber injection molding machine.

[0081] Specifically, the quality inspection module determines whether the product is qualified by detecting three defect parameters: the smoothness of the product surface, whether there are air bubbles in the product, and the product quality error. When one or more of the three defect parameters are unqualified, the product is unqualified.

[0082] Furthermore, the quality detection module includes an image collection unit for collecting product images. The quality detection module divides the product image into a number of pixel blocks, and then obtains the overall image similarity S1 by calculating the similarity of adjacent pixel blocks, and compares the calculated similarity S1 with the similarity S preset in the quality detection module:

[0083] When S1<S, the product surface is not smooth, and then the quality inspection module increases the transfer time according to the difference ΔS between S1 and S2. The larger the difference, the larger the adjustment value.

[0084] When S1≥S, the product surface is smooth.

[0085] It is understandable that when the quality detection module collects product images, a rough image will cause a large difference in similarity between adjacent pixel blocks, while a smooth image will cause a small difference in similarity between adjacent pixel blocks.

[0086] It is understandable that when the transfer time is too short, the rubber cannot be effectively melted and retains some shape, which will result in an uneven surface. Therefore, the transfer time is adjusted through the similarity parameter.

[0087] Furthermore, the quality detection module detects the actual volume V2 and the actual mass M1 of the product. The quality detection module obtains the product mass M2 by V2×ρ according to the formula M=ρ×V, and then compares the values ​​of M1 and M2:

[0088] When M1<M2, there are bubbles in the product, and then the quality inspection module increases the pressure parameter according to the difference ΔM between M1 and M2. The larger the difference, the larger the adjustment value.

[0089] When M1≥M2, the product contains bubbles.

[0090] It can be understood that when there are no bubbles in the product, its mass is equal to the product of volume and density, and when there are bubbles in the product, its mass is less than the product of volume and density. At the same time, the size of the difference in mass between the two represents the number of bubbles.

[0091] It is understandable that when the transfer pressure is too low, the rubber cannot fully fill the mold, resulting in bubbles in the product, so the pressure parameters should be adjusted according to the number of bubbles in the product.

[0092] Furthermore, the quality detection module compares the measured actual product quality M1 with the product quality M:

[0093] When M1<M, there is an error in product quality, and then the quality detection module increases the required rubber quality parameter according to the M difference ΔM1 of M1, and the value of ΔM1 is the increased parameter value.

[0094] It is understandable that when the actual mass of the product is less than the expected mass of the product, it means that the rubber has been lost during the transfer process, and the difference in mass between the two is the loss amount, so the required rubber mass can be adjusted according to the mass difference.

[0095] Furthermore, during the production process, the detection module monitors the temperature and pressure during the transfer. Once the values ​​of the two exceed the set maximum values, the machine operation is immediately stopped and an alarm is sounded to avoid danger in time.

[0096] See also Figure 2 As shown, in some other embodiments of the present application, when the scanning device of the detection module is damaged, or the special shape of the mold makes it impossible to effectively obtain the product volume, the manual quality test includes:

[0097] Step 1: Turn on the machine and install the mold into the transfer mechanism.

[0098] Step 2, click Start, select Manual mode, and click Start production

[0099] Step 3: Manually input the transfer time parameters and the required rubber quality parameters and confirm

[0100] Step 4: The control module controls the mold transfer mechanism to deliver the required rubber material into the mold, and then moves the remaining rubber material back to its original position.

[0101] Step 5: The mold is closed and transfer injection begins. The control module controls the transfer injection mechanism to increase the mold temperature and pressure to the set parameter values.

[0102] Step 6: When the preset time is reached, stop heating and pressurizing, end the transfer, and the control module controls the cooling system to quickly cool the mold.

[0103] Step 7: The detection module detects that the mold has cooled to the set temperature, and the cooling is ended. The control module controls the transfer mechanism to open the mold and controls the ejection mechanism to eject the rubber product.

[0104] Step 8: The staff checks whether the product is qualified. If it is qualified, the production quantity is set and automatic production begins. If it is unqualified, the staff adjusts the transfer parameters according to the product defects and restarts the quality test.

[0105] It is understandable that the manual control mode does not mean that every product must be manually controlled. Instead, after the transfer parameters are manually adjusted and pass the quality test, the rubber transfer machine can automatically produce according to the set parameters.

[0106] In another preferred embodiment based on the above embodiment, refer to Figure 3 As shown, this embodiment provides a control system applied to a rubber injection molding machine, including:

[0107] The detection module is used to collect product mold volume information and monitor the temperature and pressure during the transfer process in real time;

[0108] A data processing module is used to generate transfer temperature parameters, transfer pressure parameters, transfer time parameters, and required rubber material quality parameters according to the product mold volume information collected by the detection module;

[0109] A control module, used for controlling the rubber transfer molding machine to produce products according to the transfer temperature parameters, transfer pressure parameters, transfer time parameters, and required rubber material quality parameters generated by the data processing module;

[0110] The quality inspection module is used to check whether the product is qualified and adjust the injection pressure parameters, injection time parameters, and the required rubber quality parameters;

[0111] When one or more of the three defect parameters, namely, product surface smoothness, product bubble and product quality error, are unqualified, the product is unqualified, and then the transfer pressure parameter, transfer time parameter and required rubber material quality parameter are automatically adjusted according to the defect parameters;

[0112] The information storage module is used to store the transfer temperature of various types of rubber materials, the density of various types of rubber materials, and the product transfer parameters, which are automatically used when the product is produced again without the need for re-testing.

[0113] It is understandable that the above-mentioned control method and system applied to the rubber injection molding machine have the same beneficial effects, which will not be described in detail here.

[0114] See also Figure 4 The present invention provides a rubber transfer molding machine, which adopts the above-mentioned control method and system applied to the rubber transfer molding machine, including: a main control box 100, an oil tank 200, a frame 300, a base 400, an upper seat 500, an ejection mechanism 600, an upper mold moving mechanism 700, and an upper film pulling mechanism 800;

[0115] Specifically, a control panel 110 is arranged on an outer wall of the main control box 100, an integrated circuit board is arranged on the inner wall corresponding to the control panel, a detection module, a data processing module, a control module and a quality detection module are integrated on the integrated circuit board, and a motor and an oil circuit board are arranged inside the main control box 100 for providing power for the rubber injection molding machine; the top of the oil tank 200 is fixedly connected to the bottom of the main control box 100; the top of the frame 300 is connected to the bottom of the oil tank 200; a body is arranged above the frame 300, and the interior of the body includes four columns, and a base 400 is arranged on the outside of the four columns; an ejection mechanism 600 is arranged on one side of the base 400; an upper seat 500 is arranged above the base 400 and located on the outside of the four columns; an upper drawing mold mechanism 800 is arranged above one side of the upper seat 500; and an upper moving mold mechanism 700 is arranged on the outside of the column.

[0116] It is understandable that during transfer, the rubber material enters the transfer mechanism through the upper mold moving mechanism 70, and the rubber material is removed after the transfer is completed to avoid the rubber material from being heated and vulcanized. The rubber material can be recycled for multiple times, saving rubber material.
