Technical Field

[0001] The utility model belongs to the technical field of magnet cleaning, and particularly relates to an automatic reciprocating planar cleaning device. Background Technique

[0002] Each magnet in the magnet assembly (hereinafter referred to as the product) is connected by glue. After degumming, it needs to be assembled into a carrier for storage and transportation; after the product is degummed, there may still be glue residues on its surface. Moreover, during the subsequent production process of the product, dust will fall or there will be oil stains caused by manual contact. The glue residues, dust or oil stains will all affect the surface tension of the product, making it inconvenient for subsequent bonding processes and reducing the qualified rate of finished products. Therefore, it is necessary to clean the surface of the product.

[0003] The existing cleaning process is that workers use lint-free cloth dipped in alcohol to clean the surface of the product. When cleaning manually, there will be problems such as incomplete cleaning and missed cleaning of some products, resulting in unqualified surface adhesion of the product, low qualified rate of finished products, low efficiency, and high labor cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic reciprocating planar cleaning device, which can automatically complete the cleaning of products, effectively improve production efficiency and the qualified rate of products, and reduce labor costs.

[0005] To achieve the above object, the solution of the utility model is: an automatic reciprocating planar cleaning device, including a lifting mechanism, a driving mechanism, a wiping assembly, and a spraying mechanism. The spraying mechanism and the lifting mechanism are arranged on the production line for transporting products and are arranged in sequence along the transportation direction of the products;

[0006] The driving mechanism and the wiping assembly are both arranged on the lifting mechanism. The driving mechanism includes a first servo motor, an eccentric wheel, a first connecting rod, and a linear slide rail. The first servo motor is drivingly connected to the eccentric wheel. One end of the first connecting rod is eccentrically connected to the eccentric wheel. A transverse groove is provided on the wiping assembly. The other end of the first connecting rod is slidably fitted in the transverse groove. The linear slide rail is arranged above the wiping assembly and is connected to the wiping assembly. The transverse groove is perpendicular to the linear slide rail, and the linear slide rail is perpendicular to the transportation direction of the products;

[0007] When the lifting mechanism drives the wiping assembly to descend and contact the surface of the product, the first servo motor drives the eccentric wheel to rotate, so that while the first connecting rod reciprocates in the transverse groove, the wiping assembly reciprocates horizontally along the linear slide rail to wipe the product.

[0008] Further, the driving mechanism further includes a driving frame and a second connecting rod. The first servo motor is disposed on the top of the driving frame. The eccentric wheel is disposed inside the driving frame and is connected to the first servo motor through the second connecting rod. Two support arms are provided on both sides of the bottom of the driving frame, and linear slide rails are disposed at the bottoms of the two support arms.

[0009] Further, the wiping assembly includes a wiping head, a fixing plate, and a connecting plate. Both sides of the connecting plate are respectively connected to the two linear slide rails. A transverse groove is disposed on the top surface of the middle part of the connecting plate. The fixing plate is detachably mounted on the bottom surface of the connecting plate. The wiping head is fixed to the bottom of the connecting plate.

[0010] Further, the fixing plate and the connecting plate are magnetically connected.

[0011] Further, a fixing disc is disposed on the top surface of the connecting plate. The fixing disc is disposed below the eccentric wheel, and a transverse groove is provided on the fixing disc.

[0012] Further, the wiping head is made of a nano sponge material, and a dust-free cloth is wrapped around the outer periphery of the wiping head.

[0013] Further, the lifting mechanism includes a second servo motor and a lead screw sliding platform. The second servo motor is drivingly connected to the lead screw sliding platform, and the driving mechanism is fixed on the lead screw sliding platform.

[0014] Further, a conveyor belt for conveying products is provided on the production line. The driving mechanism and the wiping assembly are located above the conveyor belt. The lifting mechanism is disposed on one side of the conveyor belt. The spraying mechanism is an inverted U-shaped mechanism, and both ends of the spraying mechanism are respectively fixed on both sides of the conveyor belt, so as to be erected on the production line.

[0015] Further, a photoelectric induction switch for sensing products is provided on the spraying mechanism.

[0016] Further, a guiding mechanism is further provided on the production line. The guiding mechanism includes four guiding plates and two guiding rods. Two guiding plates are respectively provided on both sides of the conveyor belt. The lifting mechanism and the spraying mechanism are disposed between the four guiding plates. The inner ends of the guiding plates are located above the conveyor belt. Both ends of the guiding rods are respectively connected to the inner ends of the two guiding plates on the same side, and the two guiding rods are parallel to each other to prevent the products from shifting.

[0017] After adopting the above solution, the beneficial effects of the present utility model are as follows:

[0018] The utility model sets a lifting mechanism and a spraying mechanism on the assembly line, and the lifting mechanism and the spraying mechanism are arranged in sequence along the transportation direction of the product. The driving mechanism and the wiping assembly are both arranged on the lifting mechanism. After the product is assembled and degummed, it is directly conveyed to the spraying mechanism and the lifting mechanism by the assembly line in sequence. The spraying mechanism first sprays alcohol on the surface of the product, and then the lifting drive drives the wiping assembly to descend to a suitable position, that is, the position where the wiping assembly can contact the surface of the product to wipe the surface of the product. Then, the first servo motor drives the eccentric wheel to rotate. Since the eccentric wheel is eccentrically connected to one end of the first connecting rod, the other end of the first connecting rod is slidably fitted in the transverse groove of the wiping assembly. The wiping assembly is also connected with a linear slide rail in cooperation. The transverse groove is perpendicular to the linear slide rail, and the linear slide rail is perpendicular to the transportation direction of the product. Therefore, when the eccentric wheel rotates, the first connecting rod will reciprocate in the transverse groove, and the wiping assembly will reciprocate horizontally along the linear slide rail, so as to reciprocally wipe the surface of the product perpendicular to the transportation direction of the product, complete the cleaning action, and remove the dust, oil stains and residual glue on the surface of the product.

[0019] The utility model uses the structure of the cooperation of the eccentric wheel, the first connecting rod, the transverse groove and the linear slide rail to convert the rotational drive of the first servo motor into a horizontal reciprocating drive, so that the wiping assembly makes a horizontal reciprocating motion similar to manual wiping of the product, realizes automatic cleaning, can effectively improve the production efficiency and the product qualification rate, reduce the labor cost, and is applicable to the cleaning of all flat products, with good versatility.

[0020] In addition, the lifting mechanism and the spraying mechanism are both arranged on the assembly line. After the product assembly and degumming are completed, it is automatically transported to the spraying mechanism and the lifting mechanism for spraying alcohol and cleaning, realizing automatic feeding and discharging, without the need to set up loading and unloading structures, further reducing the cost.

[0027] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] As Figures 1-4 shown, the present utility model provides an automatic reciprocating planar cleaning device, including a lifting mechanism 1, a driving mechanism 2, a wiping assembly 3, and a spraying mechanism 4. The spraying mechanism 4 and the lifting mechanism 1 are arranged on an assembly line 5 for transporting a product 6 and are arranged in sequence along the transportation direction of the product 6. A conveyor belt 51 for transporting the product 6 is provided on the assembly line 5. After the product 6 is assembled and degummed, it is first sent to the spraying mechanism 4. The spraying mechanism 4 is controlled by a solenoid valve and can spray atomized alcohol on the surface of the product 6. Then the product 6 is sent to the lifting mechanism 1. The driving mechanism 2 and the wiping assembly 3 are provided on the lifting mechanism 1. The lifting mechanism 1 drives the wiping assembly 3 to descend to a suitable position, that is, a position where the wiping assembly 3 contacts the surface of the product 6 and can wipe the surface of the product 6. The driving mechanism 2 drives the wiping assembly 3 to reciprocate horizontally to perform a cleaning action on the surface of the product 6, so as to remove dust, oil stains, and glue residues on the surface of the product 6.

[0029] With particular reference to Figures 2-3 , the driving mechanism 2 can be a horizontally arranged linear movement module, and the wiping assembly 3 is driven by the movement module to reciprocate horizontally. And this linear movement module can be driven by mechanisms such as a cylinder and a screw rod. However, the present utility model adopts a structure that converts the rotational motion of a motor into a horizontal reciprocating motion. Specifically, the driving mechanism 2 includes a first servo motor 21, an eccentric wheel 22, a first connecting rod 23, and a linear slide rail 24. The first servo motor 21 is connected to the rotation axis of the eccentric wheel 22 and can drive the eccentric wheel 22 to rotate. One end of the first connecting rod 23 is eccentrically connected to the eccentric wheel 22. A horizontal groove 341 is provided on the wiping assembly 3. The other end of the first connecting rod 23 is slidably fitted in the horizontal groove 341. The linear slide rail 24 is arranged above the wiping assembly 3 and is connected to the wiping assembly 3. The horizontal groove 341 is perpendicular to the linear slide rail 24. The linear slide rail 24 is perpendicular to the transportation direction of the product 6.

[0030] After the wiping assembly 3 moves down to a suitable position, the first servo motor 21 drives the eccentric wheel 22 to rotate. Since the eccentric wheel 22 is eccentrically connected to one end of the first connecting rod 23, the other end of the first connecting rod 23 slides in the transverse groove 341 of the wiping assembly 3. The wiping assembly 3 is also connected with a linear slide rail 24. The transverse groove 341 is perpendicular to the linear slide rail 24. The linear slide rail 24 is perpendicular to the transportation direction of the product 6. Therefore, when the eccentric wheel 22 rotates, the first connecting rod 23 will reciprocate in the transverse groove 341 to laterally decompose the force of the rotation of the eccentric wheel 22. The wiping assembly 3 makes a reciprocating horizontal motion along the linear slide rail 24 to longitudinally decompose the force of the rotation of the eccentric wheel 22. Therefore, the wiping assembly 3 can reciprocate and wipe the surface of the product 6 in a direction perpendicular to the transportation direction of the product 6 to complete the cleaning action and remove dust, oil stains and residual glue on the surface of the product 6. Moreover, the lifting mechanism 1 and the spraying mechanism 4 are both arranged on the assembly line 5. After the product 6 is assembled and debonded, it is automatically transported to the spraying mechanism 4 and the lifting mechanism 1 for spraying with alcohol and cleaning, realizing automatic feeding and discharging, without setting up loading and unloading structures, further reducing costs.

[0031] Furthermore, the driving mechanism 2 also includes a driving frame 25 and a second connecting rod 26. The first servo motor 21 is arranged on the top of the driving frame 25, and the eccentric wheel 22 is arranged inside the driving frame 25. The rotation axis of the eccentric wheel 22 is connected to the first servo motor 21 through the second connecting rod 26. The distance between the eccentric wheel 22 and the motor can be pulled apart to leave space for setting a linear slide rail 24 on the driving frame 25. Two support arms 251 are provided on both sides of the bottom of the driving frame 25. The bottoms of the two support arms 251 are both provided with linear slide rails 24. The eccentric wheel 22 and the second connecting rod 26 are arranged between the two support arms 251.

[0032] Key References Figure 3, the wiping assembly 3 includes a wiping head 31, a fixing plate 32, and a connecting plate 33. Both sides of the connecting plate 33 are respectively connected to two linear slide rails 24. A transverse groove 341 is provided on the top surface of the middle part of the connecting plate 33. A fixed disk 34 can be arranged on the top surface of the connecting plate 33. The size of the fixed disk 34 is the same as that of the eccentric wheel 22. The fixed disk 34 is located below the eccentric wheel 22 and aligned with the eccentric wheel 22. The transverse groove 341 provided in the diameter direction on the fixed disk 34 can accurately cooperate with the eccentric wheel 22. The fixing plate 32 is detachably installed on the bottom surface of the connecting plate 33, and the wiping head 31 is fixed to the bottom of the connecting plate 33. The wiping head 31 can be replaced by disassembling and assembling the fixing plate 32. The fixing plate 32 and the connecting plate 33 can be set to be magnetically connected, that is, the fixing plate 32 or the connecting plate 33 is made of a strong magnetic material, or a strong magnet can be installed on the fixing plate 32 and the strong magnet to achieve the magnetic connection between the fixing plate 32 and the connecting plate 33, making the replacement of the wiping head 31 more convenient. In addition, a fixing groove for fixing the wiping head 31 is provided at the bottom of the fixing plate 32, which also facilitates the removal of the wiping head 31 from the fixing plate 32.

[0033] Furthermore, the wiping head 31 is made of a nano sponge material, and a dust-free cloth is wrapped around the outer periphery of the wiping head 31 to achieve flexible contact with the surface of the product 6, so as to clean the product 6 without damaging the product 6.

[0034] Refer to with emphasis Figure 4 , the lifting mechanism 1 includes a second servo motor 11 and a screw sliding platform 12. A fixed bracket 122 is arranged on the screw sliding platform 12. The driving frame 25 is fixed on the fixed bracket 122. The fixed bracket 122 is connected to the screw mechanism 121 of the screw sliding platform 12. The second servo motor 11 is drivingly connected to the screw mechanism 121, so that the screw mechanism 121 drives the fixed bracket 122 and the driving frame 25 to lift, thereby driving the wiping head 31 to lift.

[0035] Refer to with emphasis Figure 1, the lifting mechanism 1 is arranged on one side of the conveyor belt 51. The spraying mechanism 4 is an inverted U-shaped mechanism, and both ends of the spraying mechanism 4 are respectively fixed on both sides of the conveyor belt 51, thus being erected on the assembly line 5. Taking the direction of transporting the product 6 as the left direction as an example, the screw sliding platform 12 is arranged at the rear side of the conveyor belt 51. The driving mechanism 2 and the wiping assembly 3 are located above the conveyor belt 51. Both ends of the spraying mechanism 4 are respectively fixed on the front and rear sides of the conveyor belt 51 to straddle the conveyor belt 51. There is a photoelectric induction switch (not shown in the figure) on the spraying mechanism 4, and the photoelectric induction switch is signal-connected to the control module of the whole device. When the product 6 passes through below the spraying mechanism 4, the photoelectric induction switch senses the product 6 and sends a signal to the control module. The control module controls the spraying mechanism 4 to spray alcohol, and then controls the lifting mechanism 1 to lower the wiping head 31 to a proper position for wiping action. The interval between the lifting mechanism 1 and the spraying mechanism 4 can be set to be relatively small. After the whole product 6 is wiped, the photoelectric induction switch cannot sense the product 6, then the control module controls the wiping head 31 to lift and waits for the next product 6 to enter.

[0036] For key reference Figure 1 , there is also a guiding mechanism on the assembly line 5. The guiding mechanism includes four guiding plates 7 and two guiding rods 8. Two guiding plates 7 are respectively arranged on both sides of the conveyor belt 51. The lifting mechanism 1 and the spraying mechanism 4 are arranged between the four guiding plates 7. Specifically, two guiding plates 7 are respectively arranged on the front and rear sides of the conveyor belt 51. The two guiding plates 7 on the same side are respectively located on the left side of the lifting mechanism 1 and the right side of the spraying mechanism 4. The outer ends of the guiding plates 7 are fixed on the assembly line 5 on the front and rear sides of the conveyor belt 51, and the inner ends of the guiding plates 7 are located above the conveyor belt 51. Both ends of the guiding rod 8 are respectively connected to the inner ends of the two guiding plates 7 on the same side. The two guiding rods 8 are parallel to each other to form a limiting channel on the assembly line 5, and the product 6 is limited in the limiting channel to prevent the product 6 from deviating out of the conveyor belt 51 during wiping.

[0037] To sum up, the working process of the present utility model is as follows: First, the conveyor belt 51 conveys the product 6 to be cleaned from right to left into the limiting channel below the spraying mechanism 4. The photoelectric induction switch senses the product 6 and sends a signal. The control module controls the spraying mechanism 4 to spray alcohol on the surface of the product 6, then controls the lifting mechanism 1 to lower the wiping head 31 to a proper position, and then controls the first servo motor 21 to drive the eccentric wheel 22 to rotate, so that the first connecting rod 23 moves left and right in the transverse groove 341, and the wiping head 31 moves back and forth to wipe the surface of the product 6 to complete the cleaning action. After the product 6 leaves the wiping head 31, the photoelectric induction switch cannot sense the product 6 and sends a signal to the control module again. The control module controls the wiping head 31 to stop and lift, waits for the next product 6 to enter, and repeats the above steps to complete the cleaning of all products 6.

[0038] The above are only the preferred embodiments of the present utility model, and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
