Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, in particular to a spraying device for metal plate processing. Background Art

[0002] Surface spraying of metal plates is a process in metal plate processing. Surface spraying of metal plates is usually done by manually lifting the metal plates with hooks. Workers hold spray guns to spray the metal plates and rotate the metal plates suspended by the hooks during the spraying process. After the metal plates are sprayed, they need to be removed from the hooks, which is a complicated operation.

[0003] In the prior art, for example, Chinese patent application No. 202011056975.8 discloses an automatic flip-type plate surface spraying device, which can automatically spray both sides of the metal plate, simplifying the work flow of metal plate surface spraying for workers. However, when the equipment performs spraying on the surface of the metal plate, it drives the spray head to rotate around the metal plate, and the spray head is connected to the liquid storage tank through a hose. There are problems with this arrangement. First, the connection stability between the hose and the spray head, and second, when spraying the upward side of the metal plate, since the spray head sprays the metal plate from top to bottom, the liquid flowing out of the spray head can fully fall on the metal plate, while when spraying the downward side of the metal plate, the liquid moving from the spray head from bottom to top may not fall on the metal plate due to the gravity of the liquid itself, resulting in less spraying at the bottom of the metal plate; resulting in uneven spraying on both sides of the metal plate.

[0004] For example, a spraying device for metal plate processing disclosed in Chinese patent application No. 202221789807.4 sprays the metal plate from top to bottom from beginning to end, and can flip the metal plate by rotating the clamped metal plate. However, this process requires continuous manual operation, because the nozzle is facing the center of the metal plate. Simply keeping the metal plate surface horizontal will cause the side of the metal plate to not be sprayed. Therefore, the staff needs to constantly flip the metal plate so that the side of the metal plate is aligned with the nozzle. Therefore, the operation steps are complicated, affecting the spraying efficiency. Summary of the invention

It should be noted that the terms used in the present invention are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

[0023] The technical solutions in the embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0024] Embodiment 1:

[0025] The metal plate processing spraying device provided in Example 1 of the present invention is as follows: Figures 1 to 4 As shown, it includes a clamping mechanism 1 and a flipping mechanism 2; the clamping mechanism 1 includes a base 11, a first clamping assembly 12 and a second clamping assembly 13; the first clamping assembly 12 includes a first mounting plate 121 and a first clamping block 3; the first mounting plate 121 is fixed on the base 11; the first clamping block 3 can be rotatably fixed on the first mounting plate 121; the first clamping block 3 is horizontal compared to the rotation axis of the first mounting plate 121; the flipping mechanism 2 is fixed on the first mounting plate 121; the flipping mechanism 2 can drive the first clamping block 3 to rotate relative to The first mounting plate 121 rotates; the second clamping assembly 13 includes a second mounting plate 131 and a second clamping block 4; the second mounting plate 131 can be slidably fixed on the base 11; the sliding direction of the second mounting plate 131 relative to the base 11 is parallel to the rotation axis of the first clamping block 3 relative to the first mounting plate 121; the second clamping block 4 can be rotatably fixed on the second mounting plate 131; the second clamping block 4 is coaxial with respect to the rotation axis of the second mounting plate 131 and the rotation axis of the first clamping block 3 relative to the first mounting plate 121.

[0026] When the metal plate processing spraying device provided in Example 1 of the present invention is used, it is necessary to first use the clamping mechanism 1 to clamp the metal plate. During this period, the staff is required to manually place the metal plate between the first clamping assembly 12 and the second clamping assembly 13, and adjust the position of the second clamping assembly 13 on the bottom plate 11 by controlling the second mounting plate 131 to slide relative to the base 11, thereby changing the spacing between the first clamping assembly 12 and the second clamping assembly 13, so as to clamp metal plates of different lengths, and use the first clamping block 3 and the second clamping block 4 to clamp the opposite sides of the metal plate (the first clamping block 3 and the second clamping block 4) respectively. Block 4 is the prior art. In a spraying equipment for metal plate processing disclosed in comparative document 2, Chinese patent application number 202221789807.4, the clamping seat structure can be the first clamping block 3 and the second clamping block 4 of this embodiment), so as to complete the clamping work of the metal plate; the first clamping block 3 is driven to rotate relative to the first mounting plate 121 by the flipping mechanism 2, so as to realize the automatic rotation of the metal plate; when the staff needs to paint the metal plate, they only need to spray paint downward vertically above the (clamped) metal plate, and automatically rotate the metal plate through the flipping mechanism 2, so as to achieve uniform painting of the metal plate. Compared with the prior art, it is necessary to constantly adjust the position of the nozzle to adjust the paint spraying angle, which can easily lead to the defect of uneven paint spraying on the surface of the metal plate (the paint spraying from bottom to top is less on the surface of the metal plate than the paint spraying from top to bottom). When using the equipment of this embodiment, the staff can always keep the position of the nozzle unchanged, and change the relative position of the metal plate and the nozzle by rotating the metal plate clamped by the clamping mechanism 1 through the flipping mechanism 2, and the operation is simple; and there will be no situation where different spraying amounts are produced during the same spraying time due to changes in the nozzle position, thereby facilitating the realization of uniform spraying on the surface of the metal plate. Therefore, compared with the prior art, the structure of this embodiment can facilitate the spraying work on the surface of the metal plate and improve the spraying effect on the surface of the metal plate.

[0027] The spraying device for metal plate processing provided in Example 1 of the present invention solves the problem of complicated metal plate spraying operation and poor spraying effect in the prior art, and can improve the spraying efficiency of the metal plate surface and improve the quality of the metal plate surface spraying.

[0028] As a preferred scheme, in the present embodiment, the first clamping block 3 includes a first upper clamping plate 31, a first lower clamping plate 32 and a first slider 33; a semicircular first guide rail 1211 is provided on the first mounting plate 121; the first slider 33 can be slidably fixed in the first guide rail 1211; the flipping mechanism 2 can drive the first slider 33 to slide compared with the first guide rail 1211; the first upper clamping plate 31 and the first lower clamping plate 32 are arranged opposite to each other; the first upper clamping plate 31 and the first lower clamping plate 32 are parallel to each other; the first upper clamping plate 31 and the first lower clamping plate 32 are connected by a screw perpendicular to the surface of the first upper clamping plate; the first upper clamping plate 31 can be rotatably fixed on the first mounting plate 121; the first upper clamping plate 31 is coaxial with the semicircular axis of the first guide rail 1211 compared to the rotating shaft of the first mounting plate 121; the first slider 33 can be rotatably fixed on the first upper clamping plate 31. The present embodiment adopts the first upper clamping plate 31 (the plate surface) to stick to the upper surface of one side of the metal plate, adopts the first lower clamping plate 32 (the plate surface) to stick to the lower surface of one side of the metal plate, and then changes the relative position of the first upper clamping plate 31 and the first lower clamping plate 32 by rotating the screw, so that the first upper clamping plate 31 and the first lower clamping plate 32 respectively apply pressure to the upper and lower plate surfaces of the metal plate, thereby fixing the metal plate. Compared with the clamping seat structure in the above-mentioned comparative document 2, such fixation can increase the contact area of ​​the force-bearing point of the metal plate. When the same clamping force is applied to the metal plate, the structure of the present embodiment can reduce the local pressure on the metal plate and reduce the deformation of the metal plate due to excessive pressure during the clamping process; when the flip mechanism 2 drives the first slider 33 to slide compared to the first guide rail 1211, the first slider 33 is rotated to rotate. The sliding trajectory of a slider 33 in the first guide rail 1211 is a semicircular arc. Since the first guide rail 1211 is a semicircular arc, the first slider 33 fixed on the first guide rail 1211 is at a distance from the axis of the semicircular arc. The first slider 33 can be rotatably fixed on the first upper clamping plate 31. Therefore, the first slider 33 is at a distance from the rotation axis of the first upper clamping plate 31 (compared to the rotation of the first mounting plate 121). The first slider 33 pulls the first upper clamping plate 31 to rotate the first upper clamping plate 31, which can increase the force arm (compared with directly using a motor to coaxially fix the first upper clamping plate 31 at the rotation axis of the first upper clamping plate 31), thereby saving effort, and can prevent the first upper clamping plate 31 from directly affecting the motor output shaft when vibrating, causing the motor to be easily damaged.

[0029] Similar to the structure of the first clamping block 3, in this embodiment, the second clamping block 4 includes a second upper clamping plate 41, a second lower clamping plate 42 and a second slider 43; a semicircular second guide rail 1311 is provided on the second mounting plate 131; the second slider 43 can be slidably fixed in the second guide rail 1311; the axis of the semicircular arc of the second guide rail 1311 is coaxial with the semicircular arc axis of the first guide rail 1211; on a plane perpendicular to the axis of the first guide rail 1211 (semicircular arc), the projections of the first guide rail 1211 and the second guide rail 1311 coincide; the second upper clamping plate 41 and the second lower clamping plate 42 are arranged opposite to each other; the second upper clamping plate 41 and the second lower clamping plate 42 are parallel; the second upper clamping plate 41 and the second lower clamping plate 42 are connected to each other by a screw perpendicular to the surface of the second upper clamping plate; the second slider 43 can be rotatably fixed on the second upper clamping plate 41. When the second clamping block 4 clamps the metal plate, the distance between the second upper clamping plate 41 and the second lower clamping plate 42 is changed, and one side edge of the metal plate (i.e., the side edge opposite to the metal plate clamped by the first clamping block 3) is fixed by friction. When the spraying process is performed, the first clamping block 3 is driven to rotate by the flipping mechanism 2, which will drive the metal plate to rotate. The rotation of the metal plate will drive the second clamping block 4 to rotate in the opposite direction. The second clamping block 4 is provided with a rotating shaft as a follower, which is used to fix the metal plate and stabilize the rotating shaft position of the metal plate.The first guide rail 1211 and the second guide rail 1311 are both set to be semicircular arc shape because after the metal plate is flipped 180°, the two side plate surfaces of the metal plate can be directed to the fixed spray head at different angles, thereby realizing spraying on the front and back sides of the metal plate. The purpose of setting the semicircular arc guide rail is to make the first slider 33 and the second slider 43 have extreme positions, that is, when the first slider 33 and the second slider 43 move to the ends of the semicircular arc of the first guide rail 1211 and the second guide rail 1311, the first clamping block 3 and the second clamping block 4 will not be able to continue to rotate, thereby limiting the postures of the first clamping block 3 (relative to the first mounting plate 121) and the second clamping block 4 (relative to the second mounting plate 131), thereby facilitating the fixing of the metal plate (because when the staff fixes the metal plate, the angles of the first clamping block 3 and the second clamping block 4 (the surfaces of the fixed metal plate) compared to the ground can be unified, so that the first upper clamping plate 31 and the second upper clamping plate 41 The plate surfaces are coplanar. By setting the distance between the first lower clamping plate 32 and the first upper clamping plate 31, and the distance between the second lower clamping plate 42 and the second upper clamping plate 41, the first lower clamping plate 32 and the second lower clamping plate 42 are coplanar, so that the metal plate can slide against the first lower clamping plate 32 and the second lower clamping plate 42 until the metal plate slides to the center of the first clamping block 3 and the second clamping block 4 (the center is the rotation axis of the first clamping block 3) and is fixed. Therefore, this structure is convenient for The staff fixed that if the first guide rail 1211 and the second guide rail 1311 are simply set to be circular, it is difficult for the plate surfaces of the first lower clamping plate 32 and the second lower clamping plate 42 to be parallel when the metal plate is not clamped. The steps of adjusting the plate surfaces of the first lower clamping plate 32 and the second lower clamping plate 42 to be parallel will be very cumbersome. In this embodiment, it can be easily achieved by only moving the first slider 33 to the end of the first guide rail 1211 and the second guide rail to the end of the second guide rail 1311.

[0030] In order to specifically realize that the flip mechanism 2 drives the first slider 33 to slide relative to the first guide rail 1211, as a preferred solution, in this embodiment, the flip mechanism 2 includes a first motor 21 and a first crank 22; the first crank 22 is fixed on the output shaft of the first motor 21; the output shaft of the first motor 21 is coaxial with the semicircular arc axis of the first guide rail 1211; and the end of the first crank 22 is rotatably fixed on the first slider 33. The rotation of the output shaft of the first motor 21 can drive the rotation of the first crank 22, thereby driving the first slider 33 fixed at the other end of the first crank 22 to move. The motion trajectory of the first slider 33 is an arc with the output shaft of the first motor 21 as the axis and the length of the first crank 22 (the length between the first motor output shaft 21 and the axis of the first crank 22 that can rotatably fix the first slider 33) as the radius. Therefore, when the first motor 21 rotates, the first slider 33 moves in an arc trajectory, thereby realizing the movement of the first slider 33 on the semicircular arc first guide rail 1211.

[0031] In order to avoid that when the first clamping block 3 rotates, the metal plate needs to be used as a structure to transmit the force of the second clamping block 4 to rotate, so that the metal plate is easily deformed and the quality of the metal plate is affected, as a preferred solution, in this embodiment, the clamping mechanism 1 also includes a transmission rod 14; the first clamping block 3 and the second clamping block 4 are connected through the transmission rod 14. By setting the transmission rod 14 to connect the first clamping block 3 and the second clamping block 4, the first clamping block 3 and the second clamping block 4 can rotate synchronously, which can also ensure that the plate surfaces of the first upper clamping plate 31 and the second upper clamping plate 41 are level, which is convenient for fixing the metal plate.

[0032] After spraying, the staff needs to remove the metal plate from the first clamping block 3 and the second clamping block 4. This removal operation is cumbersome because on the one hand, the staff needs to avoid the relative friction between the metal plate and the first clamping block 3 and the second clamping block 4 affecting the quality of the metal plate, and on the other hand, they also need to avoid the paint on the metal plate from sticking to themselves. In this embodiment, a plurality of first rollers 311 are rotatably fixed on the first upper clamping plate 31; the rotating shafts of the first rollers 311 are parallel to the plate surface of the first upper clamping plate 31; the rotating shafts of the first rollers 311 are parallel to each other. ; The minimum distance from the rim of the first roller 311 to the first lower clamping plate 32 is smaller than the distance between the first upper clamping plate 31 and the first lower clamping plate 32 relative to the plate surface; a plurality of second rollers 411 are rotatably fixed on the second upper clamping plate 41; the rotating axes of the second rollers 411 are parallel to the plate surface of the second upper clamping plate 41; the rotating axes of the second rollers 411 are parallel to each other; the minimum distance from the rim of the second roller 411 to the second lower clamping plate 42 is smaller than the distance between the second upper clamping plate 41 and the second lower clamping plate 42 relative to the plate surface. After the metal plate is sprayed, the first motor 21 is controlled to rotate so that the first upper clamping plate 31 and the second upper clamping plate 41 are under the metal plate, and the surfaces of the first upper clamping plate 31 and the second upper clamping plate 41 are tilted. At this time, the staff loosens the clamping of the metal plate by the first clamping block 3 and the second clamping block 4 by turning the bolts. The metal plate can slide downward along the surfaces of the first upper clamping plate 31 and the second upper clamping plate 41 through the rotation of the first roller 311 and the second roller 411. The metal plate can move downward due to its own gravity and the component force in the direction of the surface of the first upper clamping plate 31. The metal plate can automatically slide away from the first clamping block 3 and the second clamping block 4.

[0033] To facilitate the sliding of the second mounting plate 131 relative to the base 11, in this embodiment, a pushing mechanism 5 is also included; the pushing mechanism 5 includes a second motor 51, a threaded rod 52 and a guide block 53; the threaded rod 52 is transmission-fixed on the output shaft of the second motor 51; the second motor 51 can drive the threaded rod 52 to rotate; an internal thread is provided in the guide block 53 to cooperate with the threaded rod 52; the guide block 53 is fixed on the threaded rod 52; a guide groove 111 is provided on the base 11; the guide block 53 can be slidably fixed in the guide groove 111; the extension direction of the guide groove 111 is perpendicular to the plate surface of the first mounting plate 121; the second mounting plate 131 is fixed on the guide block 53. The output shaft of the second motor 51 rotates to drive the threaded rod 52 to rotate. The threaded rod 52 rotates, and the guide block 53 is restricted to slide in the guide groove 111. Therefore, the guide block 53 does not rotate. The rotating thread of the threaded rod 52 will push the guide block 53 to slide relative to the guide groove 111, thereby making the second mounting plate 131 slide relative to the guide groove 111, and the sliding direction is perpendicular to the board surface of the first mounting plate 121.

[0034] As a preferred solution, in this embodiment, a spraying mechanism 6 is also included; the spraying mechanism 6 includes a fixed plate 61 and a plurality of spray heads 62; the fixed plate 61 is fixed above the base 11; the surface of the fixed plate 62 is horizontal; a plurality of fixing holes are provided on the fixed plate 61; the fixing holes are provided at equal intervals; the axis of the fixing holes is perpendicular to the surface of the fixed plate; the spray heads 62 are fixed in the fixing holes; the mouth of the spray heads 62 is vertically downward; during the rotation of the first clamping assembly 12 and the second clamping assembly 13, the spray heads 62 are always above the first clamping assembly 12 and the second clamping assembly 13. In this embodiment, the spray head 52 is arranged above the (fixed) metal plate, which can reduce the waste of the spraying liquid (compared with the spray head 52 being arranged on the side of the metal plate, part of the liquid will fall and be lost on the path between the spraying and the metal plate, and the liquid will not reach the surface of the metal plate due to its own gravity, and will bounce off the surface of the metal plate and fall and be wasted).
