Description

Technical Field

[0001] This invention relates to the field of liquid crystal panel manufacturing technology. Specifically, it relates to a cleaning apparatus and system for a film conveying unit. Background Technology

[0002] In the production of LCD panels, a large number of foam cassettes are required for the recycling of glass films to be processed. Over time, material residue accumulates inside these cassettes. Currently, the production line relies entirely on manual cleaning of each cassette, which is not only inefficient but also results in poor cleaning of the glass fragments and dust due to their hardness. This residue can easily cause damage to the glass films to be processed during subsequent use of the foam cassettes. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device and system for a diaphragm conveying unit, which solves the problem of low cleaning efficiency and poor cleaning effect of existing glass diaphragm conveying units when cleaning fine particles such as glass fragments and dust.

[0004] In a first aspect, the present invention provides a cleaning apparatus for a diaphragm conveying unit, which can be placed on a working surface. The cleaning apparatus for the diaphragm conveying unit includes:

[0005] A support frame that has a support section that can be moved away from the work surface.

[0006] The tilting frame includes a conveyor roller unit and a side frame. The conveyor roller unit has a conveying surface that can roll along the conveying direction. The side frame is disposed to the side of the conveyor roller unit on the conveying surface. The middle part of the side frame is rotatably mounted on a support about a tilting axis. The tilting axis is perpendicular to the conveying direction, allowing the conveying surface to rotate between a position away from the working surface and a position towards the working surface.

[0007] A snap-fit ​​component is movably mounted on the side frame in a direction oriented towards the conveyor surface. A blower is mounted on the support frame near the work surface. The blower's blowing direction is oriented towards the tilting frame and it is capable of blowing.

[0008] In one embodiment of the cleaning apparatus for the film conveying unit of the present invention, the film conveying unit is a carrier unit that can be transferred between processes via a conveyor belt during the processing of a liquid crystal panel. The film conveying unit has a bottom that can be placed on the conveyor surface of the conveyor belt. It has two parallel long edges that are opposite to a bottom protrusion and a wide edge that is perpendicular to the long edges and opposite to the bottom protrusion. The long edges, wide edges, and bottom of the film conveying unit enclose a film receiving cavity. The bottom includes a rectangular bottom surface.

[0009] The height of the support from the working surface is greater than half the length of the edge.

[0010] The length and width dimensions of the conveying surface correspond to the length and width dimensions of the rectangular bottom surface, so that the rectangular bottom surface of the diaphragm conveying unit can cover the conveying surface.

[0011] The conveyor roller unit comprises multiple parallel rotating rollers that can rotate along the conveying direction. The rotation of the rotating rollers is controlled by a conveyor motor. The conveyor motor is controlled by a conveyor motor control terminal so that the film conveying unit can move along the conveying direction by means of the rotation of the rotating rollers.

[0012] The cleaning device of the membrane conveying unit also includes a flipping motor. When the flipping motor receives a flipping command, it drives the conveying surface to face the working surface. When the flipping motor receives a reset command, it drives the conveying surface to face away from the working surface.

[0013] The cleaning device for the diaphragm conveying unit also includes a cleaning controller. The cleaning controller is a programmable controller with input and output terminals. The output terminal is connected to the control terminals of the conveying motor and the tilting motor.

[0014] A flip position sensor is installed on the side frame, and its output is connected to the input of the cleaning controller. When the conveying surface is facing the working surface, the flip position sensor sends a flip information.

[0015] In one embodiment of the cleaning apparatus for the film conveying unit of the present invention, the side frames are a first side frame and a second side frame arranged in parallel. The extending directions of the first side frame and the second side frame are parallel to the conveying direction. The first side frame and the second side frame each form opposing surfaces. The opposing surfaces of the first side frame and the second side frame are both oriented towards the conveying surface. The distance between the opposing surfaces of the first side frame and the second side frame is greater than the width of the width edge of the film conveying unit.

[0016] The locking mechanism is configured as a first locking mechanism and a second locking mechanism. Both the first and second locking mechanisms include: a locking seat, a locking cylinder, and locking claws. The locking seat is fixedly connected to the portions of the first and second side frames opposite to each other. The locking cylinder is mounted on the locking seat. The cylinder rod of the locking cylinder extends towards the conveying surface and is perpendicular to the faces of the first and second side frames opposite to each other.

[0017] The gripper is located at the extended end of the cylinder rod. The gripper includes a width-direction gripping plate and a top gripping plate perpendicular to the width-direction gripping plate. The surface of the width-direction gripping plate can be perpendicular to the conveying surface. The surface of the top gripping plate can be parallel to the conveying surface. The width-direction gripping plate and the top gripping plate form a gripping angle. The height of the gripping angle corresponds to the distance between the conveying surface and the thickness direction height of the diaphragm conveying unit. The angle of the gripping angle is 90°~95°.

[0018] A pressure sensor is installed at the connection point between the extended end of the cylinder rod and the chuck. The pressure sensor can sense the pressure between the extended end of the cylinder rod and the chuck. The output terminal of the pressure sensor is connected to the input terminal of the cleaning controller.

[0019] At the snap-fit ​​corner, a corner pressure sensor can be installed on the top snap-fit ​​plate facing the conveying surface. The corner pressure sensor can sense the pressure between the corner and the edge of the diaphragm conveying unit. The sensor's output terminal is connected to the input terminal of the cleaning controller.

[0020] The output of the cleaning controller is connected to the drive end of the locking cylinder of the first locking component and the second locking component, respectively.

[0021] Infrared position sensors are installed on the opposing surfaces of the first and second side frames. When the diaphragm conveying unit is located on the conveying surface, the infrared position sensors generate obstruction level information. When the diaphragm conveying unit is not located on the conveying surface, the infrared position sensors generate vacancy level information. The sensing output terminal of the infrared position sensor is connected to the input terminal of the cleaning controller.

[0022] In one embodiment of the cleaning apparatus for the diaphragm conveying unit of the present invention, an end-positioning member is further included. The end-positioning member includes a fixed beam, an end cylinder, and an end plate. The fixed beam is fixed between a first side frame and a second side frame in the direction of the conveying roller unit toward the working surface. The end cylinder is connected to the fixed beam. The cylinder rod of the end cylinder is movable along a set extension direction, between an extended position and a engaged position. The set extension direction is perpendicular to the conveying surface. The end plate is connected to the outer end of the cylinder rod of the end cylinder. The surface of the end plate is perpendicular to the conveying surface.

[0023] The end cylinder can receive initial commands and positioning commands.

[0024] When the end cylinder receives the initial command, the cylinder rod driving the end cylinder is in the extended position. When the cylinder rod of the end cylinder is in the extended position, the cylinder rod drives the plate surface of the end plate to a position away from the conveying surface.

[0025] When the end cylinder receives a positioning command, the cylinder rod driving the end cylinder is in a snap-fit ​​position. The cylinder rod drives the end plate to protrude from the conveying surface and be located in the conveying direction, so that the end plate can form a blocking position for the blocking diaphragm conveying unit on the conveying surface.

[0026] The control end of the end cylinder is connected to the input end of the cleaning controller.

[0027] In one embodiment of the cleaning device of the membrane conveying unit of the present invention, after the input end of the cleaning controller receives the feeding information, it detects the sensing information of the infrared position sensor. If the sensing information of the infrared position sensor is an empty level information, the output end of the cleaning controller sends a positioning command to the control end of the end cylinder, driving the plate surface of the end plate to protrude from the conveying surface.

[0028] The output of the cleaning controller drives the control end of the conveyor motor so that the diaphragm conveying unit is carried on the conveying surface and moves along the conveying direction to the position where it is limited by the end plate.

[0029] If the cleaning controller detects that the infrared position sensor readings indicate an obstruction level, it sends cylinder drive information to the locking cylinders of the first and second locking components, respectively. Within a set pre-tightening time, it receives the first pressure sensor value from the first locking component and the second pressure sensor value from the second locking component.

[0030] In the first case, if the ratio of the first pressure sensor value to the second pressure sensor value is greater than the ratio of the second pressure sensor value to the first pressure sensor value, the pre-pressure to be obtained is based on the total pre-pressure value, the first pressure sensor value, and the second pressure sensor value.

[0031] Then continue to drive the locking cylinder of the second locking component or the locking cylinder of the first locking component until the value of the second pressure sensor reaches the pre-tightening force value.

[0032] If the value of the second pressure sensor reaches the preload value, the cleaning controller sends a flipping command to the flipping motor.

[0033] In the second scenario, if the value of the first pressure sensor equals the value of the second pressure sensor, the preload to be balanced is obtained based on the total preload value and the value of the first pressure sensor. The corresponding clamping time is then obtained based on the preload to be balanced and the clamping time matching information from the corresponding historical data.

[0034] The clamping cylinders of the second and first clamping components continue to operate until the clamping time is reached. The cleaning controller sends a flipping command to the flipping motor.

[0035] In one embodiment of the cleaning apparatus of the diaphragm conveying unit of the present invention, in a third case, the first angle pressure sensor value of the first snap fastener and the second angle pressure sensor value of the second snap fastener are received.

[0036] If there is a difference between the value of the first angle pressure sensor and the value of the second angle pressure sensor, the preload force to be applied to the angle can be obtained based on the total preload value, the value of the first angle pressure sensor, and the value of the second angle pressure sensor.

[0037] If the difference between the first angle pressure sensor value and the second angle pressure sensor value is greater than a set value, then the smaller of the two values ​​is obtained. Based on the angle pressure sensor corresponding to this smaller value, the angle re-tightening clamping information is obtained from the corresponding first or second clamping information.

[0038] Continue driving the clamping cylinder corresponding to the re-tightening clamping information until the angle pressure sensor value corresponding to the clamping cylinder corresponding to the angle re-tightening clamping information reaches the angle pre-tightening force value.

[0039] If the pre-tightening force value for the bend is reached, the output of the cleaning controller sends a flipping command to the flipping motor.

[0040] In one embodiment of the cleaning apparatus for the diaphragm conveying unit of the present invention, the receiving cavity of the diaphragm conveying unit includes a first cavity and a second cavity of equal size arranged along its length. The cavity walls of the first cavity and the second cavity are inclined surfaces sloping outwards. The angle of the inclined surfaces is 45° to 60°. An internal crossbeam is formed between the first cavity and the second cavity.

[0041] The purging components are configured as a first-side purging component and a second-side purging component.

[0042] Both the first and second side purging components include an axial extension direction. The axial extension direction is perpendicular to the conveying direction. The purging component has an air cavity along the axial extension direction, and circular air holes and elongated air holes parallel to the axial extension direction are sequentially formed on the surface of the purging component along the axial extension direction, and are connected to the ventilation cavity.

[0043] The circular or elongated air holes of the first and second side purging components are arranged opposite to each other, and the blowing direction of the circular or elongated air hole of the first side purging component forms a wind convergence angle of 90° to 120° with the blowing direction of the circular or elongated air hole of the second side purging component.

[0044] This allows the air holes and elongated air holes of the first side blowing element to reach the middle of the first cavity, and the air holes and elongated air holes of the second side blowing element to reach the middle of the second cavity, so that the air blown by the first side blowing element and the air blown by the second side blowing element converge at the crossbeam inside the cavity, forming a cleaning vortex inside the first and second cavities.

[0045] The air chamber is connected to the air supply system. The control terminal of the air supply system supplies air according to the air supply control command, and the control terminal of the air supply system is connected to the output terminal of the cleaning controller.

[0046] When the output of the cleaning controller sends a flip command, and the input of the cleaning controller receives the flip information from the flip position sensor, the output of the cleaning controller sends an air supply control command to make the first side blowing component and the second side blowing component form a cleaning vortex inside the first cavity and the second cavity.

[0047] In one embodiment of the cleaning apparatus for the diaphragm conveying unit of the present invention, the cleaning apparatus for the diaphragm conveying unit further includes:

[0048] The external frame cabinet consists of an upper frame cabinet and a lower frame cabinet. A support frame is installed between the upper and lower frame cabinets.

[0049] On both sides of the upper frame cabinet corresponding to the extension direction of the conveying direction, channels corresponding to the cross-sectional shape and size of the diaphragm conveying unit are formed. The first and second side purging components are respectively installed in the lower frame cabinet at the corresponding positions in the channels on both sides.

[0050] In one embodiment of the cleaning apparatus for the diaphragm delivery unit of the present invention, it further includes:

[0051] The lower intake duct is located at the bottom of the lower frame. The lower intake duct includes a storage cavity, the upper part of which is a storage opening. The size of the storage opening corresponds to the cross-sectional size of the bottom of the lower frame. The intake duct gradually narrows from the storage opening towards the working surface to form an intake channel.

[0052] The suction channel is connected to an air intake system with a suction pump. The suction pump is driven by suction control information. When the suction control information is received, the air intake system generates a gas suction force from the storage port to the suction channel, which sucks the object in the storage cavity out of the suction channel.

[0053] The output of the cleaning controller is connected to the control terminal of the air intake system. When the output of the cleaning controller issues an air supply control command, it sends an intake control message to the air intake system so that the object in the storage cavity is sucked out of the intake channel.

[0054] A second aspect of the present invention provides a cleaning system for a membrane conveying unit, comprising a cleaning device for the membrane conveying unit as described in the embodiments of the present invention and a material conveyor belt capable of conveying the membrane conveying unit. The conveying direction of the material conveyor belt can follow the conveying direction of the cleaning device for the membrane conveying unit.

[0066] To provide a clearer understanding of the technical features, objectives, and effects of the invention, specific embodiments of the invention are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0067] In this document, "illustrative" means "serving as an example, illustration, or description," and any illustrations or embodiments described herein as "illustrative" should not be construed as a more preferred or advantageous technical solution. For the sake of brevity, each figure only schematically shows the parts relevant to this exemplary embodiment, and they do not represent the actual structure or true proportions of the product.

[0068] Figure 1 This is a schematic diagram illustrating the structure of a cleaning device for a membrane delivery unit in one embodiment of the present invention. (Refer to...) Figure 1 In a first aspect, the present invention provides a cleaning device for a diaphragm conveying unit, which can be placed on a working surface 100. The cleaning device for the diaphragm conveying unit includes: a support frame 10, a flipping frame 20, a snap-fit ​​component 30, and a blowing component 40.

[0069] Reference Figure 1 Among them, support frame 10 (in Figure 1 (A portion of which is indicated by a double-dotted line) has a support 11 that can be moved away from the working surface 100.

[0070] Reference Figure 1 The tilting frame 20 includes a conveyor roller unit 21 and a side frame 22. The conveyor roller unit 21 has a conveying surface 23. The conveying surface 23 is capable of rolling along the conveying direction A. The side frame 22 is disposed on the side of the conveyor roller unit 21 on the conveying surface 23. The middle part of the side frame 22 is rotatably disposed on the support part 11 about the axial direction of the tilting shaft 24, that is, the tilting shaft 24 is disposed in the middle of the side frame 22. The tilting shaft 24 is rotatably connected to the support part 11 (in the form of a support plate in the figure) through bearings, so that the tilting shaft 24 can rotate from 0° to 180° and from 180° to 360° under the drive of the tilting motor 25. In the figure, the tilting motor 25 drives the tilting shaft 24 through a transmission gear.

[0071] Reference Figure 1 The axial direction of the rotating shaft 24 is perpendicular to the conveying direction A, so that the conveying surface 23 can be positioned away from the working surface 100. Figure 1 The position in the middle and the position facing the working surface 100 (e.g.) Figure 2 Rotate between the positions in the middle. Figure 2 The dashed line in the figure shows the flipping process of the flipping frame 20 along the B direction.

[0072] Reference Figure 1 The latching member 30 is movably mounted on the side frame 22 in a direction that faces the conveying surface 23. Thus, the latching member 30 can latch onto the edge of the film conveying unit 90 (i.e., the foam plastic material box). The blowing member 40 is positioned on the support frame 10 near the working surface 100. The blowing direction of the blowing member 40 is towards the direction of the tilting frame 20 and it can perform blowing. The blowing member 40 can be implemented using an air knife.

[0073] Reference Figure 3 Therefore, the working process of the cleaning device of the membrane conveying unit of the present invention is as follows: Figure 3 As shown, the film conveying unit 90 (i.e., the LCD panel material bin) is conveyed to the conveying surface 23 of the flipping frame 20 via a material conveyor belt. The film conveying unit 90 (i.e., the LCD panel material bin) is then secured to both sides of the material bin by the snap-fit ​​device 30. The flipping frame 20 is then driven to rotate. Figure 2 Position, activate the purging component 40 to purge the inside of the film conveying unit 90 (i.e., the LCD panel material box) to complete the cleaning of the inside of the film conveying unit 90 (i.e., the LCD panel material box).

[0074] In particular, for small glass fragments of liquid crystal, some will fall off after the film conveying unit 90 is flipped. Then, the inside of the film conveying unit 90 is cleaned by blowing air through the blower. Under the action of high-pressure gas, the small glass fragments of liquid crystal inserted into the foam material, i.e., the shallow surface layer of the film conveying unit 90, are thoroughly cleaned. This ensures a complete cleaning of the film conveying unit 90 (i.e., the liquid crystal panel material box), thus preventing scratches on the glass film surface from residues in the film conveying unit 90 (i.e., the liquid crystal panel material box) during subsequent production. The high-pressure gas has an outlet pressure of 0.22 MPa and a flow rate of 0.17 liters / second.

[0075] Reference Figure 3 In one embodiment of the cleaning apparatus for the film conveying unit of the present invention, the film conveying unit 90 is a carrier unit that can be transferred between processes via a conveyor belt during the processing of the liquid crystal panel. The film conveying unit 90 has a bottom that can be placed on the conveying surface (the upper surface of the conveyor belt). It has two parallel long edges that are opposite to the bottom protrusion and a wide edge that is perpendicular to the long edges and opposite to the bottom protrusion. The long edges, wide edges, and bottom of the film conveying unit 90 enclose a film receiving cavity. The bottom includes a rectangular bottom surface.

[0076] Reference Figure 3 The support part 11 is positioned at a height greater than half the length of its edge from the working surface 100. This ensures that the diaphragm conveying unit 90 can be smoothly rotated.

[0077] Reference Figure 3 The length and width dimensions of the conveying surface 23 correspond to the length and width dimensions of the rectangular bottom surface, so that the rectangular bottom surface of the film conveying unit 90 can cover the conveying surface 23. The conveying roller unit 21 includes multiple parallel rotating rollers that can rotate along the conveying direction A. The rotating rollers are controlled to rotate by a conveying motor (not shown in the figure). The conveying motor is controlled by a conveying motor control terminal so that the film conveying unit 90 can move along the conveying direction A by rotating the rotating rollers. The conveying motor model can be DPR-AD-50-W-25JSHF-W550.

[0078] Reference Figure 3 The cleaning device of the membrane conveying unit also includes a tilting motor 25. When the tilting motor 25 receives a tilting command, it drives the conveying surface 23 to rotate towards the working surface 100; when the tilting motor 25 receives a reset command, it drives the conveying surface 23 to rotate away from the working surface 100. The tilting motor can be a Mitsubishi HG-KN43B servo motor with a driver: MR-JE-40B.

[0079] The cleaning device for the diaphragm conveying unit also includes a cleaning controller (not shown in the figure). The cleaning controller can be implemented using a programmable logic controller (PLC), which has input and output terminals. The output terminal is connected to the control terminal of the conveying motor and the control terminal of the tilting motor 25. In this invention, the program control of the cleaning controller can be achieved using ladder diagrams as an auxiliary tool, thereby programming all the electrical control functions of this invention.

[0080] Reference Figure 4 A flip position sensor 51 is installed on the side frame 22, and its output is connected to the input of the cleaning controller. When the conveying surface 23 is facing the working surface 100, the flip position sensor 51 sends a flip signal. The flip position sensor can be an Omron EESX674 slot-type photoelectric sensor.

[0081] Reference Figure 1 and Figure 5 In another embodiment of the cleaning apparatus for the membrane conveying unit of the present invention, the side frames 22 are a first side frame 221 and a second side frame 222 arranged in parallel. The extending directions of the first side frame 221 and the second side frame 222 are parallel to the conveying direction A. The first side frame 221 and the second side frame 222 each form opposing surfaces. The opposing surfaces of the first side frame 221 and the second side frame 222 are both arranged towards the conveying surface 23. The distance between the opposing sides of the first side frame 221 and the second side frame 222 is greater than the width of the width edge of the membrane conveying unit 90.

[0082] Reference Figure 5 The card connector 30 is configured as a first card connector 301 and a second card connector 302. (Refer to...) Figure 6 Both the first latching component 301 and the second latching component 302 include: a latching seat 31, a latching cylinder 32, and a latching claw 33. The latching seat 31 is fixedly connected to the portions of the first side frame 221 and the second side frame 222 that are opposite to each other. The latching cylinder 32 is mounted on the latching seat 31. The cylinder rod 34 of the latching cylinder 32 extends towards the conveying surface 23 and is perpendicular to the faces of the first side frame 221 and the second side frame 222 that are opposite to each other. The latching cylinder is a JMGPM20-10-M9B from SMC Corporation.

[0083] Reference Figure 6 A clamp 33 is disposed at the extended end of the cylinder rod 34. The clamp 33 includes a width-direction clamping plate 35 and a top clamping plate 36 perpendicular to the width-direction clamping plate 35. The surface of the width-direction clamping plate 35 can be perpendicular to the conveying surface 23. The surface of the top clamping plate 36 can be parallel to the conveying surface 23. The width-direction clamping plate 35 and the top clamping plate 36 form a clamping angle. The height of the clamping angle corresponds to the thickness direction height of the conveying surface 23 plus the diaphragm conveying unit 90. The angle of the clamping angle is 90°~95°, thereby achieving smooth clamping of the diaphragm conveying unit 90.

[0084] Reference Figure 6 A pressure sensor 37 is installed at the connection between the extended end of the cylinder rod 34 and the jaw 33. The pressure sensor 37 can sense the pressure between the extended end of the cylinder rod 34 and the jaw 33. The sensing output terminal of the pressure sensor 37 is connected to the input terminal of the cleaning controller. The pressure sensor is a domestically produced RLP131M.

[0085] Reference Figure 6 At the snap-fit ​​corner, a snap-fit ​​plate 36 can be mounted on the surface facing the conveying surface 23 with a snap-fit ​​pressure sensor 38. The snap-fit ​​pressure sensor 38 can sense the pressure between the snap-fit ​​corner and the edge of the diaphragm conveying unit 90. The sensing output terminal of the snap-fit ​​pressure sensor 38 is connected to the input terminal of the cleaning controller, thereby realizing the acquisition of the snap-fit ​​pressure. The pressure sensor mentioned above is a domestically produced RLP131M.

[0086] The output of the cleaning controller is connected to the drive end of the locking cylinder 32 of the first locking component 301 and the second locking component 302, respectively.

[0087] Infrared position sensors are installed on the opposing surfaces of the first side frame 221 and the second side frame 222. When the diaphragm conveying unit 90 is located on the conveying surface 23, the infrared position sensor generates an obstruction level information. When the diaphragm conveying unit 90 is not located on the conveying surface 23, the infrared position sensor generates an empty position level information. The sensing output terminal of the infrared position sensor is connected to the input terminal of the cleaning controller. The infrared position sensor used is an Omron E3Z-D61.

[0088] Reference Figure 7 In another embodiment of the cleaning apparatus for the diaphragm conveying unit of the present invention, an end-positioning member 60 is further included. The end-positioning member 60 includes a fixing beam 61, an end cylinder 62, and an end plate 63. The fixing beam 61 is fixed between the first side frame 221 and the second side frame 222 in the direction of the conveying roller unit 21 toward the working surface 100. The end cylinder 62 is connected to the fixing beam 61. The cylinder rod 34 of the end cylinder 62 is movable in a set extension direction, between an extended position and a engaged position. The set extension direction is perpendicular to the conveying surface 23. The end plate 63 is connected to the outer end of the cylinder rod 34 of the end cylinder 62. The plate surface of the end plate 63 is perpendicular to the conveying surface 23. The aforementioned end cylinder is an SMC JMGPM20-10-M9B.

[0089] The end cylinder 62 can receive initial commands and positioning commands. When the end cylinder 62 receives the initial command, the cylinder rod 34 driving the end cylinder 62 is in the extended position. When the cylinder rod 34 of the end cylinder 62 is in the extended position, the cylinder rod 34 drives the plate surface of the end plate 63 to be away from the conveying surface 23.

[0090] When the end cylinder 62 receives a positioning command, the cylinder rod 34 driving the end cylinder 62 is in the latching position. The cylinder rod 34 causes the plate surface of the end plate 63 to protrude from the conveying surface 23 and be positioned in the conveying direction A, so that the plate surface of the end plate 63 can form a blocking position on the conveying surface 23 to block the diaphragm conveying unit 90. The control end of the end cylinder 62 is connected to the input end of the cleaning controller. On the one hand, it plays a good limiting role for the diaphragm conveying unit 90. On the other hand, it can also work with the latching device to achieve better clamping of the diaphragm conveying unit 90. Considering that the diaphragm conveying unit 90 is made of rigid foam material, multi-point fixation during cleaning can balance the forces at each fixation point and reduce the impact of local clamping force on the strength of the rigid foam material box.

[0091] In another embodiment of the cleaning device of the diaphragm conveying unit of the present invention, after receiving the feeding information, the input terminal of the cleaning controller detects the sensing information of the infrared position sensor. If the sensing information of the infrared position sensor is an empty level, the output terminal of the cleaning controller sends a positioning command to the control terminal of the end cylinder 62, driving the plate surface of the end plate 63 to protrude from the conveying surface 23. The infrared position sensor used is an Omron E3Z-D61.

[0092] The output of the cleaning controller drives the control end of the conveyor motor so that the diaphragm conveying unit 90 is carried on the conveying surface 23 and moves along the conveying direction A to the position where it is limited by the plate surface of the end plate 63.

[0093] When the cleaning controller detects that the infrared position sensor readings indicate an obstruction level, it sends cylinder drive information to the locking cylinders 32 of the first locking member 301 and the second locking member 302, respectively. Within a set pre-tightening time, it receives the first pressure sensor value from the first locking member 301 and the second pressure sensor value from the second locking member 302. The aforementioned first pressure sensor is a domestically produced RLP131M.

[0094] In the first case, if the ratio of the first pressure sensor value to the second pressure sensor value is greater than the ratio of the second pressure sensor value to the first pressure sensor value, the pre-pressure to be obtained is based on the total pre-pressure value and the values ​​of the first and second pressure sensors.

[0095] Then continue to drive the locking cylinder 32 of the second locking member 302 or the locking cylinder 32 of the first locking member 301 until the value of the second pressure sensor reaches the pre-tightening force value.

[0096] If the value of the second pressure sensor reaches the preload value, the cleaning controller sends a flipping command to the flipping motor 25.

[0097] In the second case, if the value of the first pressure sensor is equal to the value of the second pressure sensor, then the preload to be balanced is obtained based on the total preload value and the value of the first pressure sensor; and the corresponding clamping time is obtained based on the clamping time matching information in the corresponding historical data and the preload to be balanced.

[0098] Continue driving the clamping cylinder 32 of the second clamping component 302 and the clamping cylinder 32 of the first clamping component 301. After the clamping time is reached, the cleaning controller sends a flipping command to the flipping motor 25.

[0099] In another embodiment of the cleaning apparatus of the diaphragm delivery unit of the present invention, in a third case, the first angle pressure sensor value of the first snap fastener 301 and the second angle pressure sensor value of the second snap fastener 302 are received.

[0100] If there is a difference between the value of the first angle pressure sensor and the value of the second angle pressure sensor, the preload force to be applied to the angle can be obtained based on the total preload value, the value of the first angle pressure sensor, and the value of the second angle pressure sensor.

[0101] If the difference between the value of the first angle pressure sensor and the value of the second angle pressure sensor is greater than a set value, then the smaller value between the first angle pressure sensor value and the second angle pressure sensor value is obtained. Based on the angle pressure sensor 38 corresponding to the smaller value, the angle re-tightening clamping connector 30 information is obtained from the corresponding first clamping connector 301 information or second clamping connector 302 information.

[0102] Continue driving the snap-fit ​​cylinder 32 corresponding to the information of the re-tightening snap-fit ​​30 until the value of the angle pressure sensor 38 corresponding to the snap-fit ​​cylinder 32 corresponding to the information of the angle re-tightening snap-fit ​​30 reaches the angle pre-tightening force value.

[0103] If the preload value of the bend angle is reached, the cleaning controller sends a flipping command to the output flipping motor 25.

[0104] In another embodiment of the cleaning apparatus for the membrane conveying unit of the present invention, the receiving cavity of the membrane conveying unit 90 includes a first cavity and a second cavity of equal size arranged along its length. The cavity walls of the first cavity and the second cavity are inclined surfaces sloping outwards. The angle of the inclined surfaces is 45° to 60°. An internal beam is formed between the first cavity and the second cavity.

[0105] Reference Figure 8 The purging member 40 is configured as a first-side purging member 401 and a second-side purging member 402. Both the first-side purging member 401 and the second-side purging member 402 include an axial extension direction. The axial extension direction is perpendicular to the conveying direction A. The purging member 40 is provided with an air cavity along the axial extension direction, and circular air holes and elongated air holes parallel to the axial extension direction are sequentially formed on the surface of the purging member 40 along the axial extension direction, and are connected to the air cavity.

[0106] Reference Figure 8 The circular or elongated air holes of the first side blowing member 401 and the second side blowing member 402 are arranged facing each other, and the blowing direction of the circular or elongated air hole of the first side blowing member 401 and the blowing direction of the circular or elongated air hole of the first side blowing member 401 form a wind convergence angle C of 90° to 120°.

[0107] Reference Figure 8 This allows the air holes and elongated air holes of the first side blowing member 401 to blow into the middle of the first cavity. It also allows the air holes and elongated air holes of the second side blowing member 402 to blow into the middle of the second cavity, so that the airflow from the first side blowing member 401 and the second side blowing member 402 converges at the crossbeam inside the cavity, forming a cleaning vortex inside both the first and second cavities.

[0108] The air chamber is connected to the air supply system. The control terminal of the air supply system supplies air according to the air supply control command, and the control terminal of the air supply system is connected to the output terminal of the cleaning controller.

[0109] When the output of the cleaning controller sends a flip command, and the input of the cleaning controller receives the flip information from the flip position sensor 51, the output of the cleaning controller sends an air supply control command to cause the first side blowing member 401 and the second side blowing member 402 to form cleaning vortices D1 and D2 inside the first and second chambers. Thus, multiple blowing and cleaning functions can be achieved with a single air output.

[0110] Reference Figure 9 In another embodiment of the cleaning apparatus for the diaphragm conveying unit of the present invention, the cleaning apparatus for the diaphragm conveying unit further includes:

[0111] The external frame cabinet 71 includes an upper frame cabinet 72 and a lower frame cabinet 73. A support frame 10 is provided between the upper frame cabinet 72 and the lower frame cabinet 73. For ease of illustration of the internal structure, Figure 9 As shown in the diagram, the external frame cabinets are arranged without any obstructions. In another embodiment, as... Figure 10 As shown, its external frame cabinet has an external cover.

[0112] On both sides of the upper frame cabinet 72 corresponding to the extension direction of the conveying direction A, two side channels 74 are formed, corresponding to the cross-sectional shape and size of the diaphragm conveying unit 90. The first side purging member 401 and the second side purging member 402 are respectively disposed on the lower frame cabinet 73 at the corresponding positions of the two side channels 74.

[0113] Reference Figure 9 In another embodiment of the cleaning apparatus for the diaphragm conveying unit of the present invention, it further includes:

[0114] The lower intake duct 81 is located at the bottom of the lower frame. The lower intake duct 81 includes a storage cavity, the upper part of which is a storage opening. The size of the storage opening corresponds to the cross-sectional size of the bottom of the lower frame. The intake channel 82 gradually narrows from the storage opening towards the working surface 100.

[0115] The suction channel 82 is connected to an air intake system with a suction pump. The suction pump is driven by the suction control information. When the suction control information is received, the air intake system generates a gas suction force from the storage port to the suction channel 82, which sucks the object in the storage cavity out of the suction channel 82.

[0116] The output of the cleaning controller is connected to the control terminal of the air intake system. When the output of the cleaning controller issues an air supply control command, it sends an intake control message to the air intake system so that the object in the storage cavity is sucked out from the intake channel 82.

[0117] Reference Figure 10 A second aspect of the present invention provides a cleaning system for a membrane conveying unit, comprising a cleaning device for the membrane conveying unit as described in the above embodiments of the present invention and a material conveyor belt 91 capable of conveying the membrane conveying unit. The conveying direction A of the material conveyor belt can continue the conveying direction A of the cleaning device for the membrane conveying unit.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
