DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] An automatic film stacking machine comprises a film stacking frame 1, a feeding device 2, a filter membrane temporary storage device 3, a filter membrane conveyor belt 4 and a film stacking device 5; the feeding device 2 and the filter membrane temporary storage device 3 are both arranged on the film stacking frame 1; the filter membrane temporary storage device 3 comprises a plurality of filter membrane temporary storage racks 30, and the filter membrane temporary storage device 3 is arranged on at least one side of the input end of the filter membrane conveyor belt 4; the stacking device 5 is arranged at the output end of the conveyor belt 4. The specific working principle is as follows: a variety of different filter membranes are placed on the filter membrane temporary storage rack 30, and each filter membrane is stacked in layers. When one of the filter membranes needs to be stacked, the loading device 2 will move to the top of the filter membrane, clamp the filter membrane, and then place the filter membrane on the filter membrane conveyor belt 4. The filter element often requires multiple filter membranes to be stacked. Therefore, the loading device 2 will clamp different filter membranes in a certain order according to needs, and then arrange them in order and place them on the filter membrane conveyor belt 4. The filter conveyor belt 4 will convey the filter membrane forward. The automatic membrane stacking machine of the present invention can realize stacking of multiple different filter membranes in a certain order, with a high level of automation, which can effectively reduce labor costs and improve production efficiency.

[0034] Furthermore, the feeding device 2 includes a frame 21, a beam 22, a beam driving member 23, a vertical guide plate 24, a guide plate driving member 25, a lifting driving member 26 and a feeding clamping mechanism 27; so the beam 22 is arranged at the output end of the beam driving member 23, and the beam 22 can be slidably arranged on the frame 21; the vertical guide plate 24 is arranged at the output end of the guide plate driving member 25, and the vertical guide plate 24 can be slidably arranged on the beam 22; the feeding clamping mechanism 27 is arranged at the output end of the lifting driving member 26, and the feeding clamping mechanism 27 can be slidably arranged on the vertical guide plate 24. Specifically, the crossbeam 22 can be slidably set on the frame 21, so that the crossbeam 22 can move on the frame 21 along the X-axis direction shown in the figure, the vertical guide plate 24 can be slidably set on the crossbeam 22, so that the vertical guide plate 24 can move on the crossbeam 22 along the Y-axis direction in the figure, and the loading and clamping mechanism 27 can be slidably set on the vertical guide plate 24, so that the loading and clamping mechanism 27 can move on the vertical guide plate 24 along the Z-axis direction in the figure, thereby realizing that the loading and clamping mechanism 27 can move in three directions of XYZ, ensuring that the loading and clamping mechanism 27 can accurately move to the top of the filter membrane and clamp the filter membrane.

[0035] Furthermore, the loading and clamping mechanism 27 includes a clamping frame 271, a buffer assembly 272, a clamping plate 273, a clamping rod 274 and a vacuum suction cup 275; the clamping frame 271 is arranged on the vertical guide plate 24; the clamping plate 273 is connected to the clamping frame 271 through the buffer assembly 272; a plurality of clamping rods 274 are provided, and a plurality of the clamping rods 274 are respectively arranged on the clamping plate 273; the clamping rod 274 is a tubular structure with two ends through, at least one end of a portion of the clamping rod 274 is connected to an external vacuum pumping device, and the other end of the portion of the clamping rod 274 is provided with the vacuum suction cup 275. Specifically, because the filter membrane is long and narrow, in order to facilitate the suction of the filter membrane, the clamping rods 274 at the two ends and the middle of the filter membrane need to be provided with the vacuum suction cups 275, and connected to the vacuum equipment for active suction, while other non-critical suction positions at other positions can be provided with other functional structures on the clamping rods 274; when other functional settings are not required, the optimal solution is to provide the vacuum suction cups 275 on all the clamping rods 274 and connect the vacuum equipment for active suction; in addition, in specific work, when the filter membrane needs to be transported, the loading and clamping mechanism 27 moves to the top of the filter membrane, and then moves downward to the filter membrane, and when the vacuum suction cups 275 under the clamping rod 274 press the filter membrane, due to the The buffering effect drives the clamping plate 273 and the clamping rod 274 to move upward, and generates a force to press the clamping plate 273 downward, so that the vacuum suction cup 275 can fit the filter membrane more closely, and at the same time, the external vacuum equipment is started to vacuum the internal cavity of the vacuum suction cup 275, so that the filter membrane is completely attached to and fixed on the vacuum suction cup 275. Since the suction cup is made of a soft material, it can not only effectively use the vacuum to fix the filter membrane and hold it stably, but also effectively protect the filter membrane and prevent it from being damaged. In addition, the buffer component 272 can provide a buffering effect when the clamping rod 274 is pressed down, which is beneficial to protecting the filter membrane, and at the same time provide a downward pressure, which is beneficial to ensure that the vacuum suction cup 275 fits the filter membrane firmly.

[0036] Furthermore, the buffer assembly 272 is provided with two groups, and the two groups of the buffer assembly 272 respectively include a first linear bearing 2721, a buffer guide rod 2722, a first buffer spring 2723 and a first stroke limiter 2724; the first linear bearing 2721 is sleeved on the buffer guide rod 2722; the first linear bearing 2721 is arranged on the clamping frame 271; one end of the buffer guide rod 2722 is connected to the clamping plate 273, and the other end of the buffer guide rod 2722 is provided with the first stroke limiter 2724; the first buffer spring 2723 is sleeved on the buffer guide rod 2722, and the first buffer spring 2723 is arranged between the clamping plate 273 and the clamping frame 271. In the specific work, when the first buffer spring 2723 is in a normal state, the first buffer spring 2723 is in a compressed state. Under the elastic force of the first buffer spring 2723, the clamping plate 273 and the clamping frame 271 tend to move away from each other, and the clamping plate 273 will drive the buffer guide rod 2722 to slide downward in the first linear bearing 2721. When the first travel limiter 2724 arranged at the upper end of the buffer guide rod 2722 drops to contact with the first linear bearing 2721, the buffer guide rod 2722 will be unable to drop, thereby limiting the height of the clamping plate 273, and the height of the clamping plate 273 and the first buffer can be controlled. The elastic force of the spring 2723 is adjusted; when the filter membrane is sucked, the clamping rod 274 is pressed down, which will push the clamping plate 273 toward the clamping frame 271, and the buffer guide rod 2722 slides upward in the first linear bearing 2721, and the first stroke limiter 2724 is pushed upward and separated from the first linear bearing 2721, thereby providing a buffering effect, so that the pressure of the vacuum suction cup 275 pressing down on the filter membrane becomes a flexible force, which is beneficial to protecting the filter membrane; in addition, at this time, the first buffer spring 2723 is further compressed, generating a greater elastic force to press the vacuum suction cup 275 at the lower end of the clamping rod 274 against the filter membrane, which is beneficial to ensure that the vacuum suction cup 275 and the filter membrane fit firmly.

[0037] Furthermore, the feeding and clamping mechanism 27 also includes an induction detection component 276, and the induction detection component 276 includes a detection rod 2761 and a pressure detection component 2762; one end of the detection rod 2761 is arranged on the clamping plate 273, and the pressure detection component 2762 is arranged on the other end of the detection rod 2761. Specifically, the clamping plate 273 is also equipped with the sensing detection component 276. When the vacuum suction cup 275 holds the filter membrane, the filter membrane will contact the pressure detection component 2762, and the pressure detection component 2762 will detect the pressure of the filter membrane on the pressure detection component 2762. When the pressure detection component 2762 detects the pressure value, it will send a signal to the external control system, and the loading and clamping mechanism 27 will move to transport the filter membrane. When the pressure detection component 2762 does not detect the pressure value, or the pressure value is too small, the control system will stop transporting after receiving the signal, and the vacuum suction cup 275 can be deflated to put down the filter membrane and then re-suction, or the filter membrane can be transported after the staff has eliminated the problem, which is helpful to detect that the vacuum suction cup 275 has sufficient suction force on the filter membrane to prevent the filter membrane from falling off during transportation.

[0038] Furthermore, the induction detection component 276 also includes a second linear bearing 2763, a second buffer spring 2764, a second stroke limiter 2765 and a spring limiter 2766; the second linear bearing 2763 is fixedly arranged on the clamping plate 273, and the second linear bearing 2763 is sleeved on the detection rod 2761; the second stroke limiter 2765 is arranged on the upper part of the detection rod 2761, and the spring limiter 2766 is arranged on the lower part of the detection rod 2761; the second buffer spring 2764 is sleeved on the detection rod 2761, and the second buffer spring 2764 is arranged between the second stroke limiter 2765 and the spring limiter 2766. Specifically, the induction detection component 276 is also provided with a buffering function. Under normal conditions, when the vacuum suction cup 275 does not hold the filter membrane, the second buffer spring 2764 is located between the second stroke limiter 2765 and the spring limiter 2766 and is in a compressed state. Under the elastic force of the second buffer spring 2764, the second stroke limiter 2765 and the spring limiter 2766 tend to move away from each other, and the spring limiter 2766 drives the detection rod 2761 to slide downward in the second linear bearing 2763. When the second stroke limiter 2765 arranged at the upper end of the detection rod 2761 drops to contact with the second linear bearing 2763, This will prevent the detection rod 2761 from descending, thereby limiting the height of the pressure detection component 2762, and the height of the pressure detection component 2762 and the elastic force of the second buffer spring 2764 can be adjusted; when the vacuum suction cup 275 holds the filter membrane, the filter membrane will push up the pressure detection component 2762 and the detection rod 2761 together, and the detection rod 2761 slides upward in the second linear bearing 2763, and the second stroke limiter 2765 pushes up and separates from the second linear bearing 2763, thereby providing a buffering effect, so that the pressure between the pressure detection component 2762 and the filter membrane becomes a flexible force, which is beneficial to protecting the filter membrane and the pressure detection component 2762.

[0039] Furthermore, the feeding and clamping mechanism 27 also includes two groups of lifting components 277, and the two groups of lifting components 277 are respectively arranged at the two ends of the clamping frame 271; the lifting component 277 includes a driving cylinder 2771, a lifting plate 2772 and a lifting column 2773; the driving cylinder 2771 is arranged on the clamping frame 271; the lifting plate 2772 is arranged at the output end of the driving cylinder 2771, and the lifting column 2773 is arranged on the lifting plate 2772. Specifically, the loading and clamping mechanism 27 can also transport a temporary storage frame for temporarily storing filter membranes. Lifting grooves are provided on both sides of the temporary storage frame. When the temporary storage frame needs to be transported, the lifting assembly 277 drives the lifting plate 2772 to open to the side through the driving cylinder 2771, and then descends to the side of the temporary storage frame. The driving cylinder 2771 drives the lifting plate 2772 to move inward, so that the lifting column 2773 is inserted into the lifting groove of the temporary storage frame, so that the loading and clamping mechanism 27 can move and drive the temporary storage frame to move.

[0040] Furthermore, the vacuum suction cup 275 is a corrugated vacuum suction cup. Specifically, the corrugated vacuum suction cup is made of rubber material, has good softness when sucking or putting down the workpiece, and can gently suck the fragile workpiece. The filter membrane is very thin and the material is also a relatively fragile material, so the corrugated vacuum suction cup is used in this embodiment to prevent damage to the workpiece and improve the effect of the suction cup sucking the filter membrane.

[0041] Furthermore, the first stroke limiter 2724, the second stroke limiter 2765 and the spring limiter 2766 are all limiter rings. Specifically, when installing the limiter ring, it is only necessary to put the limiter ring on the shaft, and then tighten the screws on the limiter ring to clamp the limiter ring, so that the limiter ring can be fixed on the shaft, and the movement of the shaft and the spring can be limited. Moreover, the installation of the limiter ring is convenient and quick.

[0042] Furthermore, the membrane temporary storage rack 30 includes a temporary storage rack 301, a temporary storage rack driving mechanism 302, a transmission mechanism 303, a transmission plate 304 and a membrane temporary storage frame 305; the transmission mechanism 303 is arranged on the temporary storage rack 301; the temporary storage rack driving mechanism 302 is in transmission connection with the transmission mechanism 303; the transmission plate 304 is provided with a plurality of plates, and the transmission plates 304 are arranged in an array on the transmission mechanism 303; each of the transmission plates 304 is detachably provided with the membrane temporary storage frame 305. Specifically, the filter membranes are stacked in the filter membrane temporary storage frame 305, and each of the different filter membrane temporary storage racks 30 respectively holds different types of filter membranes, while the filter membrane temporary storage frame 305 on the same filter membrane temporary storage rack 30 holds the same type of filter membrane, and the transmission mechanism 303 is provided with a plurality of transmission plates 304, and the plurality of transmission plates 304 are respectively provided with the filter membrane temporary storage frame 305 for holding the filter membrane, and the filter membranes stored in the filter membrane temporary storage frame 305 on the same transmission mechanism 303 are all It is the same type. When the filter membranes stored in the filter membrane temporary storage frame 305 at the front are used up, the loading device 2 for transporting the filter membrane will take away the empty filter membrane temporary storage frame 305, and then the transmission mechanism 303 where the empty filter membrane temporary storage frame 305 is located will be started to transport the filter membrane temporary storage frame 305 with the filter membranes stored at the rear to the front for membrane stacking operation. Not only can a large amount of filter membranes be stored, but also the automatic replenishment of the filter membranes can be realized, thereby improving the degree of automation of the equipment and improving work efficiency.

[0043] Furthermore, the transmission plate 304 includes a mounting plate 3041, a limiting protrusion 3042 and a mounting groove 3043; the mounting plate 3041 is fixedly arranged on the transmission mechanism 303; the limiting protrusions 3042 are respectively arranged at both ends of the mounting plate 3041; the limiting protrusion 3042 is arranged at the mounting groove 3043; both ends of the filter membrane temporary storage frame 305 are provided with mounting protrusions 3051; when the filter membrane temporary storage frame 305 is installed on the transmission plate 304, the mounting protrusion 3051 is limitedly arranged in the mounting groove 3043. Specifically, the transmission plate 304 is provided with limiting protrusions 3042 on both sides. When the filter membrane temporary storage frame 305 is fixed on the transmission plate 304, the filter membrane temporary storage frame 305 is arranged between the two limiting protrusions 3042, thereby limiting the left and right directions of the filter membrane temporary storage frame 305. In addition, the filter membrane temporary storage frame 305 and the filter membrane temporary storage frame 305 are provided with mounting protrusions 3051 at both ends. When the filter membrane temporary storage frame 305 is arranged between the two limiting protrusions 3042, the mounting protrusion 3051 is installed in the mounting groove 3043, so that the front and rear directions of the filter membrane temporary storage frame 305 are limited by the mounting groove 3043, thereby preventing the filter membrane temporary storage frame 305 from sliding on the transmission plate 304 and falling off.

Under the drive of the motor, the active rotating shaft 306 and the temporary storage rack 301 rotate relative to each other, driving the active transmission wheel 3031 to rotate, thereby driving the transmission belt 3033 to rotate around the active rotating shaft 306 and the driven rotating shaft 307, thereby driving the filter membrane temporary storage frame 305 installed on the transmission belt 3033 to move; both ends of the driven rotating shaft 307 are fixedly arranged on the temporary storage rack 301, and the driven transmission wheel 3032 is connected to the driven rotating shaft 307 through a bearing. The rotating shaft 307 is connected so that the driven transmission wheel 3032 and the driven rotating shaft 307 rotate relative to each other. The filter membrane used for the membrane stacking operation is located in the filter membrane temporary storage frame 305 at the front of the conveyor belt. When the filter membrane in the filter membrane temporary storage frame 305 at the front is used up, the filter membrane temporary storage frame 305 with the used filter membrane is moved away by the loading device 2, and then the external motor will drive the active rotating shaft 306 to rotate, thereby driving the transmission belt 3033 to rotate and transport the filter membrane temporary storage frame 305 with the filter membrane behind the transmission belt 3033 forward and transport it to the frontmost position of the transmission belt 3033. Not only is the transmission stable and the cost low, but the filter membrane loading operation can also be continuous, effectively improving production efficiency.

[0045] Furthermore, the membrane temporary storage rack 30 also includes an adjustment component 308, and the adjustment component 308 includes an adjustment plate 3081, an adjustment slot 3082 and an adjustment bolt 3083; two adjustment plates 3081 are provided, and the two adjustment plates 3081 are respectively arranged on both sides of the temporary storage rack 301; the adjustment slot 3082 is penetrated through the center of the adjustment plate 3081, and the two ends of the driven shaft 307 are respectively limited and set in the adjustment slots 3082 of the two adjustment plates 3081; the adjustment bolt 3083 is arranged on one side of the adjustment plate 3081, and extends into the adjustment slot 3082 to press the driven shaft 307, so that the driven shaft 307 can slide in the adjustment slot 3082. Specifically, both ends of the driven rotating shaft 307 are fixed to the temporary storage frame 301 through the adjusting assembly 308 respectively, and the end of the driven rotating shaft 307 is inserted into the adjusting groove 3082 and adjusted by the adjusting bolt 3083. The adjusting groove 3082 is long and parallel to the direction of the conveyor belt. The adjusting bolt 3083 is also arranged parallel to the adjusting groove 3082, and the adjusting bolt 3083 passes through the adjusting plate 3081 and is inserted into the adjusting groove 3082. The adjusting bolt 3083 can push the driven rotating shaft 307 to slide in the adjusting groove 3082, thereby adjusting the distance between the driven rotating shaft 307 and the driving rotating shaft 306, so as to adjust the tension state of the conveyor belt. It is not only convenient to install the conveyor belt, but also when the conveyor belt is loose due to long-term use, the conveyor belt can be tightened by the adjusting assembly 308 to ensure the smooth rotation of the conveyor belt.

[0046] Furthermore, the transmission mechanism 303 is provided with two groups, and the two groups of the transmission mechanism 303 are synchronously transmission-connected with the driving shaft 306 and the driven shaft 307. Specifically, the two groups of the transmission mechanism 303 operate synchronously, and the two ends of the transmission plate 304 are respectively connected with the two groups of transmission mechanisms 303. When the two groups of the transmission mechanism 303 operate synchronously, the filter membrane temporary storage frame 305 can be driven to move at the same time, so that the supporting area of ​​the transmission plate 304 is increased, the installation is more stable, and the transmission plate 304 can be balanced left and right during the movement, which is conducive to ensuring the smooth movement of the filter membrane temporary storage frame 305 and preventing the filter membrane temporary storage frame 305 from falling.

[0047] Furthermore, pulleys 3044 are respectively provided at both ends of the transmission plate 304. Specifically, when the transmission belt 3033 drives the transmission plate 304 to rotate, when the transmission plate 304 rotates to the bottom of the conveyor belt, it will contact the temporary storage rack 301, which will generate friction, affecting the smooth operation of the conveyor belt, and long-term friction will cause wear of the transmission plate 304, so the pulleys 3044 are provided at both ends of the transmission plate 304, and when the transmission plate 304 contacts the temporary storage rack 301, the pulleys 3044 will contact the temporary storage rack 301, and the pulleys 3044 will slide on the rack 21, reducing friction, so that the transmission belt 3033 rotates more smoothly.

[0048] Furthermore, the temporary filter storage rack 30 further includes a positioning support assembly 309, which includes a plurality of fixed plates 3091 and a support plate 3092. The plurality of fixed plates 3091 are arranged in an array on the temporary storage rack 301, and the support plate 3092 is arranged above the fixed plates 3091. Specifically, the fixed plates 3091 are provided with at least three pieces, and the support plates 3092 are fixed on the three fixed plates 3091. The conveyor belt is arranged on the support plates 3092. When the temporary filter storage frame 305 is installed on the transmission plate 304, the conveyor belt will be bent and deformed due to gravity, resulting in problems such as the conveyor belt not rotating smoothly. Therefore, the support plates 3092 can support the conveyor belt, effectively improve the safety and stability of transmission, and prevent the conveyor belt from bending and sinking due to the gravity of the temporary filter storage frame 305, which causes the conveyor belt to roll over due to high ground fluctuations during transportation.

[0049] Furthermore, the left and right ends of the support plate 3092 are respectively provided with limiting flanges 3093, and the front and rear ends of the support plate 3092 are respectively provided with chamfers. In specific operation, when the conveyor belt is rotating, the upper conveyor belt is limited between the limiting flanges 3093 at the left and right ends of the support plate 3092, which is conducive to ensuring that the conveyor belt is always limited between the limiting flanges 3093 during the movement, ensuring the stability of the rotation of the conveyor belt and reducing shaking; in addition, since the filter membrane temporary storage frame 305 on the transmission belt 3033 will press the conveyor belt downward, the inner side of the conveyor belt is provided with teeth meshing with the transmission wheel, and the teeth are easily stuck when sliding into the support plate 3092, so the front and rear ends of the support plate 3092 are respectively provided with chamfers, which is conducive to the smooth movement of the conveyor belt.

[0050] Furthermore, the temporary filter storage rack 30 also includes an inductive detector 3010, which is arranged at the output end of the transmission mechanism 303. Specifically, the function of the inductive detector 3010 is to detect the filter membrane in the temporary filter storage frame 305. The inductive detector 3010 in this embodiment is an infrared inductive switch. When the inductive detector 3010 detects that the filter membrane in the temporary filter storage frame 305 is used up, it will send a signal to the control device, and the control device will send a signal to control the feeding device 2 to take away the temporary filter storage frame 305 at the front, and then control the temporary storage rack driving mechanism 302 to start, drive the transmission mechanism 303, and move the temporary filter storage frame 305 at the rear to the front to wait for loading; it not only improves the automation level, reduces the labor cost, prevents the filter membrane in the temporary filter storage frame 305 from running out and causing production stagnation, but also improves production efficiency.

[0051] Furthermore, the film stacking machine also includes a filter membrane detection device 6 and a collection frame 7; the filter membrane detection device 6 is arranged on the filter membrane conveyor belt 4, and the filter membrane detection device 6 is arranged at the input end of the film stacking device 5; the filter membrane detection device 6 includes a thickness detector and a visual detector; the collection frame 7 is arranged at the output end of the filter membrane conveyor belt 4. Specifically, when the filter membrane passes through the filter membrane detection device 6, the filter membrane detection device 6 will detect the filter membrane to check whether the filter membranes are overlapped, whether the type of the filter membranes is wrong, etc. If there is no error and it is determined to be qualified, the filter membrane conveyor belt 4 will convey the filter membrane to the membrane stacking device 5, and the membrane stacking device 5 will clamp the filter membrane and perform the membrane stacking operation; if an error occurs and it is determined to be unqualified, the filter membrane conveyor belt 4 will transport the unqualified filter membrane to the end of the filter membrane conveyor belt 4, and transport the unqualified filter membrane to the collection frame 7 for processing, and then supplement the unqualified filter membrane and perform the membrane stacking operation again. The number and type of filter membranes are detected by the filter membrane detection device 6, which effectively prevents errors in membrane stacking and affects the quality of the filter element.

[0052] Furthermore, the film stacking device 5 includes a visual inspection system 51, a film stacking robot arm 52, a film stacking assembly box 53 and a finished product conveyor belt 54; the visual inspection system 51 is arranged above the filter membrane conveyor belt 4; the film stacking robot arm 52 is arranged at the output end of the filter membrane conveyor belt 4; the finished product conveyor belt 54 is arranged on one side of the film stacking robot arm 52; the film stacking assembly box 53 is arranged on the finished product conveyor belt 54.

[0053] In specific work, the visual inspection system 51 is used to detect the specific positions of the filter membrane on the filter membrane conveyor belt 4 and the stacking film assembly box 53 on the finished product conveyor belt 54, and then send the position parameters to the stacking film robot arm 52. The filter membrane is accurately transported to the stacking film assembly box 53 through the stacking film robot arm 52, and then the stacking film assembly box 53 is transported out through the finished product conveyor belt 54 to complete the stacking operation of the automatic stacking machine. It not only has a high degree of automation and reduces labor costs, but also has accurate positioning, high work efficiency and low error rate.

[0054] Furthermore, the film stacking device 5 also includes a positioning mechanism 55, which is arranged on the finished product conveyor belt 54; the positioning mechanism 55 includes a mounting rod 551, a guide rod 552 and a positioning rod 553; the mounting rod 551 is arranged at one end of the finished product conveyor belt 54; the guide rod 552 is an arc-shaped rod and is arranged at one end of the mounting rod 551; the positioning rod 553 is a straight rod, which is arranged at the other end of the mounting rod 551 and is connected to one end of the guide rod 552.

[0055] The stacking film assembly box 53 is moved along the curvature of the guide rod 552, and then moves along the positioning rod 553. Under the action of the positioning rod 553 and the side edge of the finished product conveyor belt 54, the stacking film assembly box 53 is limited between the positioning rod 553 and the side edge of the finished product conveyor belt 54. The direction and position of the stacking film assembly box 53 can be adjusted through the positioning mechanism 55 so that the direction and position of the empty stacking film assembly box 53 are the same each time, which is beneficial to improving the efficiency of the stacking film by the stacking film machine arm 52.

[0056] Furthermore, the present film stacking machine also includes an empty frame storage rack 8, the filter membrane temporary storage rack 30 is provided with a filter membrane temporary storage frame 305, the filter membrane temporary storage frame 305 is provided with an induction detector 3010, and the empty frame storage rack 8 is arranged on the filter membrane temporary storage device 3; the empty frame storage rack 8 includes a frame 81, a placement platform 82, a plurality of rollers 83, an empty frame induction switch 84 and a push rod device 85; the placement platform 82 is arranged at one end of the upper part of the frame 81; the push rod device 85 is arranged on one side of the placement platform 82; the empty frame induction switch 84 is arranged on the placement platform 82; a plurality of the rollers 83 are rotatably connected to the frame 81, and a plurality of the rollers 83 are arranged downwardly tilted on the other side of the placement platform 82.

[0057] Specifically, the empty frame storage rack 8 can be set at any position around the filter membrane temporary storage device 3 as needed. The empty frame storage rack 8 is used to store the empty filter membrane temporary storage frame 305. When the filter membrane in the filter membrane temporary storage frame 305 is used up, the loading device 2 will move the filter membrane temporary storage frame 305 with the used filter membrane to the placement platform 82. When the empty frame sensing switch 84 on the placement platform 82 detects the presence of the filter membrane temporary storage frame 305, the push rod device 85 will be started to push the filter membrane temporary storage frame 305 onto the roller 83. The filter membrane temporary storage frame 305 will slide downward on a number of rollers 83 due to the action of gravity until it slides to the lowest end and stops when it hits the frame 81. The filter membrane temporary storage frame 305 with the used filter membrane can be cached, and the empty filter membrane temporary storage frame 305 can be neatly arranged and collected by the roller 83, which is convenient for the staff to replenish the filter membrane.

[0058] The present invention proposes a control method for an automatic film stacking machine, wherein the automatic film stacking machine is connected to a control system, and the method comprises the following steps: step S1: placing different types of filter membranes in a plurality of filter membrane temporary storage racks 30; the control system receives parameter data of different types of filter membranes, a filter membrane stacking sequence, and a filter membrane stacking quantity N; step S2: starting a feeding device 2, the feeding device 2 clamps a first filter membrane according to the filter membrane stacking sequence, and places the first filter membrane on a filter membrane conveyor belt 4, starting the filter membrane conveyor belt 4, moving the first filter membrane forward for a certain distance, and recording the clamping The number of clamping times n is 1; step S3: the feeding device 2 clamps the remaining filter membranes in sequence according to the filter membrane stacking order, and places the filter membranes on the filter membrane conveyor belt 4 in sequence, and each time the filter membrane is placed on the filter membrane conveyor belt 4, the filter membrane conveyor belt 4 moves forward a distance, and the number of clamping times n is increased by 1, until the number of clamping times n is equal to the number of filter membrane stacking N; step S4: the filter membrane conveyor belt 4 transports the filter membrane to the membrane stacking device 5, and the membrane stacking device 5 performs membrane stacking operation on the filter membrane until the membrane stacking device 5 completes the stacking of all the filter membranes, and the filter membrane conveyor belt 4 and the membrane stacking device 5 stop.

[0059] Specifically, the control system is arranged on a control and data processing device such as a computer, and can transmit signals to and from the automatic membrane stacking machine. The control system is provided with a storage device for storing parameter data of different types of filter membranes, filter membrane stacking order, and filter membrane stacking quantity and other data. During operation, the distance that one end of the filter membrane conveyor belt moves each time is 1.5 times the length of the filter membrane. The control system controls the automatic membrane stacking machine to stack the filter membranes in sequence according to the filter membrane stacking order. The number of stacking membranes of a group of filter elements is N, and the number of clamping times of each filter membrane transported by the feeding device 2 is n, and the number of clamping times increases by 1 each time the feeding device 2 transports the filter membrane until the number of clamping times n is equal to the number of filter membrane stacking N, and the filter membrane transporting operation of a group of filter elements is completed. When the number of membrane stacking times of the filter membrane by the membrane stacking device 5 reaches the number of stacking times N, the membrane stacking operation of a group of filter elements is completed. This method replaces the traditional manual membrane stacking method, effectively improves the membrane stacking efficiency, and reduces the error rate of membrane stacking.

[0060] Furthermore, it also includes a filter membrane detection and processing method, in which the thickness h of the filter membrane is recorded in the parameter data of the filter membrane, and the filter membrane detection and processing method includes the following steps: Step A1: The thickness detector detects the thickness H of the filter membrane, and the control system compares the thickness H with the thickness h of the parameter data of the filter membrane in the system to determine whether the thickness H of the filter membrane is greater than 1.5 times the thickness h in the parameter data of the filter membrane. If not, step A2 is executed, and if so, it is determined to be unqualified and step A3 is executed; Step A2: The visual detector photographs the filter membrane on the filter membrane conveyor belt 4, and determines whether the filter membrane is consistent with the filter membrane in the system at this position; if not, the filter membrane is conveyed to the membrane stacking device 5 for membrane stacking, and if so, it is determined to be unqualified and step A3 is executed; Step A3: The filter membrane conveyor belt 4 conveys the unqualified filter membrane to the collection frame 7 at the end, and then the filter membrane conveyor belt 4 rotates in the opposite direction to transport the filter membrane backward, and the feeding device 2 is used to supplement the unqualified filter membrane at the front end, and then the filter membrane conveyor belt 4 rotates forward to transport the filter membrane forward.

[0061] Specifically, the method may also include inspecting and processing the filter membrane, using a thickness detector to detect the thickness of the filter membrane, and using a visual detector to detect the shape or color of the filter membrane. If an unqualified filter membrane is detected, the filter membrane conveyor belt 4 will transport the unqualified filter membrane to the collection frame 7 at the end of the filter membrane conveyor belt 4 for processing. The filter membrane conveyor belt 4 will rotate in the opposite direction and retract, replenish the unqualified filter membrane and then perform the membrane stacking operation. The number and type of filter membranes are detected by the filter membrane detection device 6, which can effectively prevent errors in membrane stacking and affect the quality of the filter element.

[0062] Furthermore, the present application proposes another filter membrane detection and processing method, in which the parameter data of the filter membrane records the thickness h of the filter membrane, the filter membrane cycle stacking sequence and the number of cycles L, and the filter membrane detection and processing method includes the following steps: Step B1: The thickness detector detects the thickness H of the filter membrane, and the control system compares the thickness H with the thickness h of the filter membrane parameter data in the system to determine whether the filter membrane thickness H is greater than 1.5 times the thickness h in the filter membrane parameter data. If not, execute step B2. If so, determine it as unqualified and execute step B3; Step B2: The visual detector photographs the filter membrane on the filter membrane conveyor belt 4, and determines the filter membrane Is it consistent with the filter membrane in the system at this position; if not, the filter membrane is conveyed to the membrane stacking device 5 for membrane stacking until all the membrane stacking operations of the cycle number L are completed. If so, it is determined to be unqualified and step B3 is executed; step B3: the membrane conveyor belt 4 transports all the remaining filter membranes in the filter membrane circulation stacking sequence where the unqualified filter membrane is located and some filter membranes in the next circulation stacking sequence to the collection frame 7, and the number of cycles is reduced by 1. When the filter membrane in the next filter membrane circulation stacking sequence that is at the same position as the unqualified filter membrane arrives under the thickness detector and the visual detector, the membrane conveyor belt 4 stops and steps B1 and B2 are executed.

[0063] Specifically, the present method also provides another filter membrane detection and processing implementation method. Since the stacked membranes of the filter element are often stacked in a continuous cycle of a filter membrane circulation stacking sequence, in the present embodiment, when an unqualified filter membrane appears, the filter membranes after the unqualified filter membrane are transported to the collection frame 7 through the filter membrane conveyor belt 4, until the filter membrane corresponding to the unqualified filter membrane position in the next filter membrane circulation stacking sequence arrives under the thickness detector and the visual detector, the filter membrane is detected, and when the filter membrane is qualified, the remaining filter membranes in the stacking sequence are added to the previous stacking sequence for stacking, and the number of cycles is reduced by 1, and then the stacking operation is continued. The present embodiment can realize the continuous forward rotation of the filter membrane conveyor belt 4. When an unqualified filter membrane appears, the qualified filter membrane of the next stacking sequence is replaced for stacking operation, thereby improving production efficiency and effectively preventing filter membrane errors from affecting the quality of the filter element.

[0064] Furthermore, the step S4 also includes the following steps: step C1: the filter membrane reaches above the film stacking robot arm 52, and the filter membrane conveyor belt 4 stops; step C2: the visual inspection system 51 detects the position of the filter membrane on the filter membrane conveyor belt 4, and the position of the film stacking assembly box 53 on the finished product conveyor belt 54; step C3: the film stacking robot arm 52 clamps the filter membrane and places the filter membrane into the film stacking assembly box 53, and records the number of film stacking; step C4: determine whether the number of film stacking is equal to the number N of filter membrane stacking, otherwise continue to stack the film, and if so, the film stacking robot arm 52 stops stacking; step C5: the finished product conveyor belt 54 starts to output the film stacking assembly box 53 stacked with filter membranes, and at the same time transports the empty film stacking assembly box 53 to one side of the film stacking robot arm 52, and the film stacking robot arm 52 starts to start the next round of film stacking operation.

[0065] Specifically, the film stacking device 5 uses a visual inspection system 51 to accurately locate the position of the filter membrane on the filter membrane conveyor belt 4 and the position of the film stacking assembly box 53 on the finished product conveyor belt 54, and then sends the position parameters to the film stacking robot arm 52. The filter membrane is accurately transported to the film stacking assembly box 53 by the film stacking robot arm 52, and then the film stacking assembly box 53 is transported out through the finished product conveyor belt 54 to complete the film stacking operation of the automatic film stacking machine. It not only has a high degree of automation and reduces labor costs, but also has accurate positioning, neatly stacked filter membranes, high work efficiency and low error rate.

[0066] Furthermore, it also includes a method for loading and unloading the filter membrane temporary storage frame, including the following steps: Step C1: The induction detector 3010 detects whether there is a filter membrane in the filter membrane temporary storage frame 305. If so, the loading device 2 continues to transport the filter membrane, otherwise the loading device 2 will clamp the empty filter membrane temporary storage frame 305 without the filter membrane and place it on the placement platform 82; Step C2: The empty frame induction switch 84 detects that the filter membrane temporary storage frame 305 is on the placement platform 82, starts the push rod device 85, and pushes the filter membrane temporary storage frame 305 onto the roller 83, and the filter membrane temporary storage frame 305 slides to the bottom of the roller 83.

[0067] Specifically, the induction detector 3010 detects whether there is a filter membrane in the filter membrane temporary storage frame 305. When the filter membrane in the filter membrane temporary storage frame 305 is used up, the induction detector 3010 will send a signal to the loading device 2, and the loading device 2 will move the filter membrane temporary storage frame 305 that has run out of filter membrane to the placement platform 82. When the empty frame sensing switch 84 on the placement platform 82 detects the presence of the filter membrane temporary storage frame 305, the push rod device 85 will be started to push the filter membrane temporary storage frame 305 onto the roller 83. The filter membrane temporary storage frame 305 will slide downward on the rollers 83 due to the action of gravity until it slides to the lowest end. The filter membrane temporary storage frame 305 that has run out of filter membrane can be cached, and the empty filter membrane temporary storage frames 305 can be neatly arranged and collected by the roller 83, so that the staff can replenish the filter membrane conveniently.
