Description

Technical Field

[0001] The invention relates to the technical field of filter gluing, in particular to a device and method for synchronously gluing two sides of an air filter. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It sends the low-dust air into the room after purification to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

[0003] The dispensing process of air filters needs to comprehensively consider factors such as the type, precision, stability and environmental impact of the dispensing equipment. By rationally selecting and optimizing the dispensing system, the sealing quality and production efficiency of the air filter can be significantly improved.

[0004] The existing glue dispensing process generally uses a glue dispensing machine to dispense glue on one side of the filter.

After the curing is completed, the filter needs to be taken out and turned over, and then glue is dispensed on the other side by the glue dispensing machine. However, when dispensing glue in this way, it is necessary to wait until the glue curing is completed before dispensing glue on the other side of the filter, which leads to complicated operation procedures and poor glue dispensing efficiency.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0046] See also Figure 1 to Figure 12 In an embodiment of the present invention, a double-sided synchronous gluing device for an air filter includes: a processing frame 1, a glue dispenser 2, a truss 3, a conveyor belt 4, a glue solid cabinet 5, a pulley, a lifting component, a support plate 8, a pushing and flipping mechanism, a clamping plate 34, a clamping mechanism, a follow-up rotating mechanism, and a spacing control component. In order to ensure that the two glue dispensers 2 can synchronously perform glue dispensing on both sides of the filter, the filter needs to be turned over to ensure the processing efficiency of the filter. When glue dispensing is required, the filter can be transported to the bottom of one of the glue dispensers 2 through the conveyor belt 4, and under the action of the glue dispenser 2, one side of the filter is glued.

[0047] When the glue dispensing is completed, the conveyor belt 4 continues to move and controls the filter to be transported to the bottom of the card plate 34. Under the action of the lifting component, the support plate 8 is controlled to move, and the card plate 34 is controlled to move to a position matching the filter by pushing the flip mechanism and the clamping mechanism. Under the action of the flip mechanism, the two card plates 34 are controlled by the clamping mechanism to move toward each other. After the filter is fixed, the filter is pushed toward the glue solidifying cabinet 5 for glue solidifying. When the glue solidifying is completed, the card plate 34 is controlled to move away from the filter under the action of the flip mechanism and the clamping mechanism, and When the card plate 34 is separated from the glue cabinet 5, the lifting assembly moves, causing the card plate 34 to move in the direction away from the conveyor belt 4. At the same time, the push-turn mechanism will control the flipping of the card plate 34 through the clamping mechanism to turn the filter over. After the flipping is completed, under the action of the push-turn mechanism and the clamping mechanism, the card plate 34 moves in the direction away from each other, so that the filter is released onto the conveyor belt 4 again. Under the action of the conveyor belt 4, the filter is controlled to move to the bottom of the other glue dispenser 2. At this time, the two glue dispensers 2 move synchronously to synchronously perform glue dispensing on both sides of the two filters.

[0048] The details are as follows, including:

[0049] A processing frame 1, and a glue dispensing machine 2 and a truss 3 symmetrically mounted on the processing frame 1, a pulley rotatably mounted on the truss 3, a conveyor belt 4 sleeved on the pulley, and a glue solidifying cabinet 5 fixedly mounted on the truss 3;

[0050] Among them, when it is necessary to dispense glue on the filter, the filter can be placed on the conveyor belt 4. At this time, the pulley will drive the conveyor belt 4 to move, thereby driving the filter to move to a position that cooperates with one of the glue dispensing machines 2. After the glue dispensing machine 2 completes the glue dispensing, the conveyor belt 4 continues to move and drives the filter to move to a clamping position. At the same time, the next filter will be transported to a position that cooperates with the glue dispensing machine 2. During the process of the glue dispensing machine 2 dispensing glue on the filter, the filter with one side of the glue can be transported to the glue solidifying cabinet 5 to solidify the glue. After the solidification is completed, the filter in the glue solidifying cabinet 5 can be taken out, turned over and placed on the conveyor belt 4. Under the action of the conveyor belt 4, the filter is transported to another glue dispensing machine 2. At this time, three filters will be processed synchronously, namely, the filters located below the two glue dispensing machines 2 and with opposite glue dispensing surfaces, and the third filter is located in the glue solidifying cabinet 5 for glue solidification.

[0051] Also includes:

[0052] See also Figure 1-Figure 4, a lifting assembly is arranged on the processing frame 1, and a support plate 8 is connected to the lifting assembly. The lifting assembly includes a support sleeve 6 installed on the truss 3 and symmetrically arranged, and a support rod 7 is slidably installed in the support sleeve 6. The support rod 7 is connected to the support plate 8. The truss 3 is also provided with a first cylinder 9 connected to the support plate 8.

[0053] In detail, in order to prevent the filter from interfering with the conveyor belt 4 when the filter is turned over, the filter needs to be lifted to a certain height. Therefore, when the height of the support plate 8 needs to be adjusted, the support plate 8 is driven to move under the action of the first cylinder 9, thereby driving the support rod 7 to move along the length direction of the support sleeve 6. The support rod 7 and the support sleeve 6 have a guiding function to ensure that the support plate 8 will not shift during movement. When the height of the support plate 8 reaches the desired position, the first cylinder 9 stops moving.

[0054] See also Figure 1-Figure 5 , Figure 7-Figure 9 , a push-turn mechanism is arranged on the support plate 8, the push-turn mechanism comprises a fixed sleeve 10 mounted on the support plate 8, two straight grooves 1002 are symmetrically opened on the fixed sleeve 10 along its length direction, the two straight grooves 1002 are connected in the circumferential direction of the fixed sleeve 10 through two first spiral grooves 1003, two guide rods 11 cooperating with the first spiral grooves 1003 are rotatably mounted on the fixed sleeve 10, the fixed sleeve 10 is provided with a protrusion 12 corresponding to and abutting the two guide rods 11, the support plate 8 A sliding component connected to the fixed sleeve 10 is provided, wherein the sliding component includes a first through groove 1001 opened on the outer wall of the fixed sleeve 10, a push plate 14 is slidably installed in the first through groove 1001, a rotating sleeve 15 slidably connected to the fixed sleeve 10 is rotatably installed on the push plate 14, a first limit block 16 that can slide along the straight groove 1002 and the first spiral groove 1003 is provided on the rotating sleeve 15, and a symmetrically arranged second cylinder 13 is provided on the support plate 8, and the output end of the second cylinder 13 is connected to the push plate 14.

[0055] It should be noted that a torsion spring is sleeved on the rotating shaft of the guide rod 11. Under the action of the torsion spring, the guide rod 11 and the protrusion 12 are in abutment state. In the initial state, under the action of the second cylinder 13, the push plate 14 is located at the end of the stroke away from the support plate 8, and the first limit block 16 is located at the end of the stroke of the straight groove 1002 away from the support plate 8. When the filter needs to be glued, at this time, under the action of the second cylinder 13, the push plate 14 is driven to move toward the support plate 8 and slide along the length direction of the first through groove 1001. The push plate 14 will drive the rotating sleeve 15 to move horizontally, thereby driving the first limit block 16 to move along the straight groove 1 002 moves in the length direction. When the first limit block 16 moves to fit with one side of the guide rod 11, the first limit block 16 drives the guide rod 11 to rotate and gradually separates from the protrusion 12. When the first limit block 16 is separated from the guide rod 11, under the action of the torsion spring, the guide rod 11 is reset, and the first limit block 16 continues to move. While the rotating sleeve 15 moves, the clamping mechanism is driven to control the two clamping plates 34 to move in a direction close to each other. When the clamping plate 34 fixes the filter after glue application, it pushes the filter to move toward the glue solidifying cabinet 5 until the filter is in the glue solidifying cabinet 5. Under the action of the glue solidifying cabinet 5, the glue on the filter is solidified.

[0056] Preferably, at this time, under the action of the conveyor belt 4, another filter is transported to the bottom of one of the glue dispensers 2 to ensure that during the filter curing process, the glue dispenser 2 dispenses glue on the new filter. When the curing is completed, the second cylinder 13 drives the push plate 14 to move in a direction away from the support plate 8, thereby driving the rotating sleeve 15 to move. The rotating sleeve 15 will drive the first limit block 16 to slide along the straight groove 1002. When the filter is out of the glue cabinet 5, the infrared sensor is used to send a command to the first cylinder 9 to make it work, controlling the support plate 8 to move far upward. The filter is moved in the direction away from the conveyor belt 4 to ensure that there will be no interference with the conveyor belt 4 when the filter is turned over. At this time, the second cylinder 13 continues to move, so that the first limit block 16 continues to move along the length direction of the straight groove 1002 until the first limit block 16 moves to the connecting position of the straight groove 1002 and the first spiral groove 1003, and the first limit block 16 will abut against the guide rod 11. Since the guide rod 11 is set at the connecting point of the straight groove 1002 and the first spiral groove 1003, and under the action of the protrusion 12, the guide rod 11 cannot rotate, Under the guidance of the guide rod 11, the first limit block 16 enters the first spiral groove 1003. At this time, the rotating sleeve 15 will rotate, so that the filter is turned over by the clamping mechanism and the clamping plate 34. When the first limit block 16 is separated from the first spiral groove 1003 and enters another straight groove 1002, the filter just rotates half a circle to complete the flipping action. At this time, the first cylinder 9 moves again and controls the filter to move toward the conveyor belt 4. At the same time, the first limit block 16 continues to move along the direction of the straight groove 1002 and under the action of the clamping mechanism Under the action of the first cylinder 9, the card plate 34 is separated from the filter, the conveyor belt 4 moves, and the filter that has been glued is controlled to enter under the other glue dispensing machine 2, and the filter that has not been glued enters under the card plate 34, and the new filter will be transported to under one of the glue dispensing machines 2. At this time, the two glue dispensing machines 2 work synchronously and perform glue dispensing on both sides of the two filters synchronously.

[0057] See also Figure 1-Figure 5 , Fig. 9 , Fig.11 , Fig.12, the support plate 8 is also provided with a clamping mechanism connected to the pushing and flipping mechanism, and the clamping mechanism is connected with a symmetrically arranged and relatively movable card plate 34, and the pushing and flipping mechanism can perform a flipping action while the clamping mechanism moves horizontally relative to the support plate 8, the clamping mechanism includes a rotating rod 17 slidably installed in the rotating sleeve 15, and a receiving plate 26 is rotatably installed at the end of the rotating rod 17, and a symmetrically arranged guide rod 25 is arranged on the receiving plate 26, and a supporting assembly is arranged on the receiving plate 26, wherein the supporting assembly includes a sliding groove 2601 opened on the receiving plate 26 and symmetrically arranged, a sliding block 27 is slidably installed in the sliding groove 2601, and a sliding plate 30 is arranged on the side wall of the sliding block 27; it also includes a guide sleeve 31 installed on the sliding plate 30, a movable rod 32 is slidably installed in the guide sleeve 31, the movable rod 32 is connected to the card plate 34, and a third spring 33 abutting against the card plate 34 is sleeved on the movable rod 32.

[0058] Furthermore, in the initial state, the guide rod 25 is located in abutment with the support plate 8, so that the card plate 34 is located above the conveyor belt 4. Since the third spring 33 has pre-compressed elastic potential energy, the movable rod 32 extends out of the guide sleeve 31 to the maximum extent, and the distance between the card plate 34 and the sliding plate 30 is maximized. Under the action of the distance control component, the sliding block 27 is located at the end of the stroke on one side of the slide groove 2601, so that the distance between the two card plates 34 is maximized. Under the action of the first cylinder 9, a certain gap is left between the card plate 34 and the conveyor belt 4. When it is necessary to cure the glue on one side of the filter, the card plate 34 is moved toward the conveyor belt 4 under the action of the first cylinder 9. At this time, the filter will be located between the two card plates. The plates 34 are located between the plates 34. At the same time, under the action of the second cylinder 13, the rotating sleeve 15 moves toward the direction of the glue solid cabinet 5. The rotating sleeve 15 will also drive the rotating rod 17 to move through the follow-up rotating mechanism, and control the two sliding blocks 27 to slide along the slide groove 2601 through the spacing adjustment component, and move in the direction of approaching each other. The sliding block 27 will also drive the sliding plate 30 to move, so as to drive the card plate 34 to move through the movable rod 32. Under the action of the card plate 34, the filter is clamped. When the clamping is completed, the rotating rod 17 will control the receiving plate 26 to move in the direction away from the support plate 8 to drive the filter to move toward the glue solid cabinet 5. When the filter is completely entered into the glue solid cabinet 5, the glue is cured under the action of the glue solid cabinet 5.

[0064] Furthermore, the guide groove can be divided into four sections, namely the first vertical groove 1701, the first annular groove 1702, the second vertical groove 1703, and the second annular groove 1704. The first vertical groove 1701, the first annular groove 1702, the second vertical groove 1703, and the second annular groove 1704 are connected to each other from head to tail and are arranged in a mouth shape. In the initial state, the guide rod 25 abuts against the support plate 8.

The first spring 19 is also in a compressed state, and at this time the first The elastic potential energy of the spring 19 is smaller than the elastic potential energy of the second spring 22. At this time, the second limit block 23 is located at the position where the first vertical groove 1701 and the second annular groove 1704 meet, and at this time, the two clamping plates 34 are in an open state, and the distance between the two is the largest. When it is necessary to clamp the filter with glue dispensed on one side, at this time, the rotating sleeve 15 is driven by the second cylinder 13 to move toward the glue cabinet 5. Since the second spring 22 provides a thrust to the connecting ring 21 in the direction away from the fixed ring 1503, and the connecting column fixed between the connecting ring 21 and the sliding ring 20 is located at the end of the second spiral groove 1502 away from the fixed ring 1503, the connecting column will not slide in the second spiral groove 1502, and under the action of the second spring 22 , ensuring that the rotating rod 17 will not rotate, and the first spring 19 and the second spring 22 will give a thrust to the rotating ring 18 to ensure that the rotating rod 17 will not move with the rotating sleeve 15, and the rotating sleeve 15 will drive the second limit block 23 to move along the length direction of the first vertical groove 1701. With the movement of the fixing ring 1503, the second spring 22 is elastically released until the elastic potential energy of the second spring 22 is less than the elastic potential energy of the first spring 19. Since the second limit block 23 is still in the first vertical groove 1701, the rotating rod 17 will not rotate, and the rotating rod 17 is in a locked state. Therefore, the sliding ring 20 and the connecting ring 21 will not move. When the second limit block 23 moves to the first vertical groove 1701 and connects with the first annular groove 1702, When the filter is in the open position, the second limit block 23 and the first vertical groove 1701 no longer provide locking force to the rotating rod 17. At this time, the elastic potential energy of the first spring 19 is greater than the elastic potential energy of the second spring 22. Therefore, the first spring 19 is elastically released and drives the connecting ring 21 and the sliding ring 20 to move toward the fixed ring 1503, so as to drive the connecting column to slide along the second spiral groove 1502. Since the first limit block 16 is located in the straight groove 1002, it is ensured that the rotating sleeve 15 does not rotate. Therefore, under the action of the connecting column and the second spiral groove 1502, the rotating rod 17 is driven to rotate, so that the two sliding blocks 27 are controlled to move in a direction close to each other through the spacing control component, so as to clamp the filter through the clamping plate 34. When the rotating rod 17 rotates,Since the guide plate 24 is slidably connected with the guide rod 25, the rotating rod 17 will not drive the receiving plate 26 to rotate. The rotating rod 17 will also control the second limit block 23 to move to the connection position between the first annular groove 1702 and the second vertical groove 1703. At this time, under the action of the second limit block 23 and the first annular groove 1702, the rotating rod 17 is driven to move synchronously with the rotating sleeve 15, and the filter is transported to the glue cabinet 5 for glue solidification through the clamping plate 34. Under the action of the guide groove, the rotating rod 17 will not move before the clamping plate 34 clamps the filter. After the clamping plate 34 fixes the filter, the rotating rod 17 moves with the rotating sleeve 15.

[0065] Preferably, when the glue is fixed, the rotating sleeve 15 moves toward the initial position, and the rotating rod 17 is driven to move synchronously by the first spring 19 and the second spring 22, thereby driving the receiving plate 26 to move. When the filter is separated from the glue fixing cabinet 5, the first limit block 16 just enters the first spiral groove 1003, and the rotating sleeve 15 will rotate, thereby controlling the receiving plate 26 to rotate through the guide plate 24 and the guide rod 25, so as to control the filter to flip through the clamping plate 34. At the same time, since the second limit block 23 is located in the second vertical groove 1703, and the second limit block 23 is fixed to the inner wall of the rotating sleeve 15, when the rotating sleeve 15 rotates, it drives the second limit block 23 to follow the movement. Under the action of the second limit block 23 and the second vertical groove 1703, the rotating rod 17 rotates synchronously to ensure that the spacing adjustment component does not move. When the first limit block 16 is separated from the first spiral groove 1003 and enters the straight groove 1002 again, the guide rod 25 just moves to the position abutting against the support plate 8, thereby The receiving plate 26 controls the rotating rod 17 to stop moving, and the rotating sleeve 15 continues to move, so that the second limit block 23 slides along the second vertical groove 1703. At the same time, the guide plate 24 compresses the second spring 22 until the elastic potential energy of the second spring 22 is greater than the elastic potential energy of the first spring 19, and the second limit block 23 is still in the second vertical groove 1703. When the second limit block 23 moves to the connection position between the second vertical groove 1703 and the second annular groove 1704, the rotating rod 17 can rotate freely, the second spring 22 is elastically released, and drives the connecting ring 21 and the sliding ring 20 to move, and under the action of the second spiral groove 1502, the rotating rod 17 rotates to control the second limit block 23 to return to the connection position between the first vertical groove 1701 and the second annular groove 1704. When the rotating rod 17 rotates, it will also drive the sliding block 27 to move in the direction away from each other through the spacing control component to control the card plate 34 to move in the direction away from each other, so that the filter is released and falls onto the conveyor belt 4.

[0066] See also Figure 1-Figure 5 , Fig. 9 , Fig.11The clamping mechanism is provided with a spacing adjustment component, and the follow-up rotating mechanism can be activated when the pushing and flipping mechanism moves, so as to control the clamping mechanism and the spacing adjustment component to control the clamping plate 34 to move closer to or farther away from each other, and the spacing adjustment component includes a third spiral groove 1705 opened on the rotating rod 17, and a movable plate 28 slidably connected to the guide rod 25 is slidably installed on the rotating rod 17, and a third limit block 2801 slidably connected to the third spiral groove 1705 is provided on the inner wall of the movable plate 28, and a connecting rod 29 hinged to the sliding block 27 is hinged on the movable plate 28.

[0067] To explain in detail, in the initial state, the rotating sleeve 15 is located at the end of the stroke away from the glue cabinet 5, and the third limit block 2801 is located at the end of the stroke of the third spiral groove 1705 toward the receiving plate 26 side, so as to control the maximum distance between the two sliding blocks 27 through the connecting rod 29. When the rotating rod 17 rotates, the third spiral groove 1705 is driven to move. Under the action of the third spiral groove 1705 and the third limit block 2801, the movable plate 28 is moved in the direction away from the receiving plate 26. The movable plate 28 will also drive the sliding block 27 to move in the direction close to the receiving plate 26 through the connecting rod 29, so as to clamp the filter through the clamping plate 34. If the rotating rod 17 is reversed, under the action of the third spiral groove 1705 and the third limit block 2801, the movable plate 28 is moved in the direction away from the receiving plate 26, so that the clamping plates 34 are moved away from each other, thereby releasing the filter.

[0068] A method for synchronously gluing air filters on both sides, comprising the following steps:

[0069] Step 1: Place the filter to be coated with glue on the conveyor belt 4 and control it to be transported to the bottom of one of the glue dispensers 2, where it is glued by the glue dispenser 2;

[0070] Step 2: After the glue is applied to one side of the filter, the conveyor belt 4 controls it to move to a position where it matches with the card plate 34. At the same time, under the action of the lifting assembly, the card plate 34 is controlled to move toward the conveyor belt 4 by pushing the flip mechanism and the clamping mechanism, so that the filter is located between the two card plates 34.

[0071] Step 3: At this time, under the action of pushing the flip mechanism, the clamping mechanism and the follower rotating mechanism are driven to move, so that the card plate 34 moves in a direction close to each other, and the filter is fixed, and the flip mechanism is pushed to continue to move, so as to transport the filter to the glue solidifying cabinet 5 through the card plate 34, so as to solidify the glue;

[0072] Step 4: After the glue is fixed, the flip mechanism is pushed to control the card plate 34 to leave the glue fixing cabinet 5. At the same time, under the action of the lifting component, the card plate 34 is controlled to move in a direction away from the conveyor belt 4, and under the action of pushing the flip mechanism, the filter is turned over by the card plate 34;

[0073] Step 5: When the flipping is completed, the lifting assembly controls the card plate 34 to move toward the conveyor belt 4 again, and under the action of pushing the flipping mechanism and the clamping mechanism, the card plate 34 moves in the direction away from each other to release the filter. The filter will fall onto the conveyor belt 4 again, and under the action of the conveyor belt 4, it will be transported to the next glue dispensing machine to perform glue dispensing on the other side of the filter.
