Description

Technical Field

[0001] The present invention relates to the field of coating equipment, and in particular to a powder spraying device for a battery energy storage box and a powder spraying process thereof. Background Art

[0002] Energy storage power stations use large-scale batteries to store surplus electricity in the power grid during off-peak periods, and return the stored electricity to the grid during peak periods to alleviate power supply shortages. Battery energy storage boxes are an important part of energy storage power stations and are used to accommodate batteries.

[0003] In the process of producing battery energy storage boxes, the box body or the plates that constitute the box body need to be painted to prevent rust. This requires the use of electrostatic powder spraying equipment. The powder coating is sprayed on the surface of the plate through the electrostatic powder spraying equipment, and then the plate is sent to the baking room. After high-temperature baking, the powder coating is leveled and solidified to form a protective layer.

[0004] The plates of battery energy storage boxes are usually large in size and usually require multiple powder spraying to ensure the coverage effect. On the existing circulating conveyor line, the plates are usually turned over and returned to their original positions. However, large-sized plates are very prone to collision when turned over, and large-sized plates are easy to shake when hung on the bracket, which is not conducive to powder spraying during the transportation process. Summary of the invention

[0011] Preferably, a waist-shaped through hole is provided on the base, and the annular conveying track is located in the waist-shaped through hole and moves. An elliptical plate is provided at the bottom of the partition, and the width between the outer wall of the elliptical plate and the inner wall of the waist-shaped through hole is not less than the diameter of the shaft rod, and the shaft rod moves in the waist-shaped limiting channel formed between the elliptical plate and the waist-shaped through hole.

[0012] Preferably, the top edge strips are arranged horizontally, and at least two vertically extending guide rods are arranged on the opposite sides of the two top edge strips, and the guide rods are inserted into the guide sleeves arranged on the mounting bracket; the top edge strips are provided with racks parallel to the guide rods, and the racks on the two top edge strips are respectively meshed and connected to the two sides of the center gear, and the center gear is rotatably installed at the center position of the mounting bracket. The mounting bracket is also fixedly installed with a rotary drive, and the center gear is transmission-connected to the working end of the rotary drive.

[0014] A powder spraying process for a battery energy storage box, applied to a powder spraying device for a battery energy storage box, comprises the following steps:

[0015] Step 1: Load the plate manually or by a robotic arm, and the top edge bar of the hanging device cooperates with the vacuum suction cup to fix the plate;

[0021] Secondly, the sliding groove of the rectangular slider in the present invention is provided with two shock-absorbing springs elastically connecting the two ends of the rectangular limit block. When the rectangular slider moves at the rounded corners and short sides of the rounded rectangular limit groove, the position of the rectangular limit block in the sliding groove of the rectangular slider can be changed by compressing the shock-absorbing springs at both ends, thereby adapting to the position movement of the sliding seat in the circular arc section of the annular conveying track, ensuring that the rectangular limit block provides a horizontal pulling force perpendicular to the straight section of the annular conveying track to the rectangular slider, so that the rectangular slider moves along the short side of the rounded rectangular limit groove.

[0022] Thirdly, the hanging device in the present invention fixes large-sized plates through top edge strips and vacuum suction cups. The presence of the shock-absorbing spring can buffer the inertia of the plates when they move to the two ends of the circular conveying track for changing direction. In conjunction with the top edge strips and vacuum suction cups, the position of the plates on the hanging device can be effectively prevented from shifting, thereby avoiding the position of the secondary powder spraying from shifting and affecting the powder spraying effect.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figures 1 to 10 :

[0036] A powder spraying device for a battery energy storage box, comprising a conveying device 1, a hanging device 2, a powder spraying gun 3 and a protective cover 4, wherein the conveying device 1 comprises a base 11 and an annular conveying track 12 mounted on the base 11, wherein the annular conveying track 12 is provided with a plurality of sliding seats 121, the hanging device 2 comprises a vertical mounting bracket 21, wherein two top side strips 22 are slidably mounted on the mounting bracket 21, wherein the top side strips 22 are provided with a plurality of vacuum suction cups 23, wherein the top side strips 22 cooperate with the vacuum suction cups 23 to fix the plate, wherein the upper and lower ends of the mounting bracket 21 are provided with vertical shaft rods 211, wherein the shaft rod 211 at the bottom of the mounting bracket 21 It is rotatably mounted on a limiting sleeve 212, a fixed seat 213 is arranged at the bottom of the limiting sleeve 212, and the fixed seat 213 is fixedly mounted on the sliding seat 121; a rectangular limiting block 214 is fixedly mounted on the top of the shaft rod 211 on the upper side of the mounting bracket 21, and the rectangular limiting block 214 is slidably mounted in a rectangular sliding block 215, and a top plate 13 is arranged above the conveying device 1 on the base 11, and a rounded rectangular limiting groove 131 is arranged on the top plate 13, and the rectangular sliding block 215 is slidably mounted in the rounded rectangular limiting groove 131, and when the annular conveying track 12 drives the hanging device 2 to move, the direction of the hanging device 2 is fixed toward the side of the powder spray gun 3.

[0037] When the powder spraying device in the present application is in use, the staff manually or automatically loads the plate with a mechanical arm. The plate is mounted on the hanging device 2. The protective cover 4 should ensure that part of the moving path of the annular conveying track 12 is located outside the protective cover 4 to facilitate the loading and unloading of the plate. Multiple plates are sequentially mounted on the hanging device 2 and follow the sliding seat 121 on the annular conveying track 12 to move through the working position of the powder spraying gun 3. The powder spraying gun 3 has several working ends connected to the powder spraying gun 3 by a linear drive, and the linear drive can be a screw slide, etc. The linear drive drives the powder spraying gun 3 to reciprocate in the vertical direction to spray powder on the plate fixed by the hanging device 2. The powder spraying gun 3 should be connected to a pump body for conveying powder through a powder conveying pipe, and the pump body is connected to the powder spraying gun 3. The storage barrel for storing powder is received, and after being sprayed with powder by the powder spraying gun 3, the annular conveying track 12 drives the hanging device 2 and the plate fixed by the hanging device 2 to move in the opposite direction to the loading position, and then passes through the powder spraying gun 3 for a second powder spraying. Since the moving path of the annular conveying track 12 is elliptical, the sliding seat 121 needs to turn 180 degrees when moving in the opposite direction on the annular conveying track 12, thereby driving the plate on the hanging device 2 to flip over. The flipping angle of the plate is too large. In this embodiment, the mounting bracket 21 of the hanging device 2 is coaxially arranged with vertical shaft rods 211 at the upper and lower ends. The shaft rod 211 at the bottom of the mounting bracket 21 is rotatably installed in the limiting sleeve 212. The limiting sleeve 212 is installed on the sliding seat 121 through the fixed seat 213. The rectangular limit block 214 connected to the shaft 211 above 21 is slidably installed in the rectangular slider 215, and the rectangular slider 215 is limitedly installed in the rounded rectangular limit groove 131 of the top plate 13. Therefore, when the mounting bracket 21 follows the sliding seat 121 to move in the straight section of the annular conveying track 12, the rectangular limit block 214 pushes the rectangular slider 215 to move in the rounded rectangular limit groove 131 of the top plate 13. When the sliding seat 121 moves to the arc section of the annular conveying track 12, the limit sleeve 212 and the fixed seat 213 follow the sliding seat 121 to move and rotate. At this time, since the rectangular slider 215 cannot rotate in the rounded rectangular limit groove 131, the mounting bracket 21 is moved around the axis of the shaft 211 in the limit sleeve 212. The movement of the limiting sleeve 212 causes the mounting bracket 21 to pull the rectangular slider 215 to move along the short side of the rounded rectangular limiting groove 131 through the rectangular limiting block 214. During this process, the hanging device 2 fixes the plate and translates along the short side of the rounded rectangular limiting groove 131 until the sliding seat 121 connected to the hanging device 2 moves to another straight section of the annular conveying track 12 and moves in the opposite direction. At this time, the plate on the hanging device 2 still remains facing the side of the powder spraying gun 3. The hanging device 2 does not flip over when the sliding seat 121 passes through the arc section of the annular conveying track 12, and only moves in the horizontal direction, thereby avoiding the problem of excessive flipping area due to excessive plate size. At the same time, the volume of the conveying device 1 can also be reduced to reasonably utilize the space.

[0038] In order to solve the problem of how to ensure the stability of the hanging device 2 when it moves around the annular conveying track 12, the following features are specifically set:

[0039] The rectangular limit block 214 and the rectangular slider 215 extend horizontally along the conveying direction of the annular conveying track 12, the length of the rectangular slider 215 is greater than the length of the rectangular limit block 214, and the rectangular limit block 214 is slidably installed in a sliding groove 216 extending along its own length direction arranged below the rectangular slider 215; the long side of the rounded rectangular limit groove 131 extends horizontally along the moving path of the rectangular limit block 214, and the width of the long side of the rounded rectangular limit groove 131 is the same as the width of the rectangular slider 215; the short side of the rounded rectangular limit groove 131 extends perpendicular to the length direction of the rectangular limit block 214, and the width of the short side of the rounded rectangular limit groove 131 is the same as the length of the rectangular slider 215 (such as Figure 6 as shown).

[0040] Two damping springs 217 are arranged in the sliding groove 216 of the rectangular sliding block 215 . The damping springs 217 are respectively located on both sides of the rectangular limiting block 214 and elastically connect the rectangular limiting block 214 and the inner wall of the rectangular sliding block 215 .

[0041] In this embodiment, the rectangular limit block 214 and the rectangular slider 215 both extend along the length direction of the straight section of the annular conveying track 12. The length of the rectangular limit block 214 is less than the length of the rectangular slider 215. Therefore, the rectangular limit block 214 can have a certain range of motion in the sliding groove 216 of the rectangular slider 215. In this embodiment, when the hanging device 2 moves along the straight section of the annular conveying track 12 driven by the sliding seat 121, the rectangular limit block 214 moves to one end of the sliding groove 216 and compresses the shock absorbing spring 217, and then drags the rectangular slider 215 to move along the long side of the rounded rectangular limit groove 131. The width of the long side of the rounded rectangular limiting groove 131 is the same as the width of the rectangular slider 215, so it can be inserted into the limiting sleeve 212 in conjunction with the shaft 211 to ensure the stability of the hanging device 2 and the plate fixed by the hanging device 2 during movement. When the sliding seat 121 moves to the arc section of the annular conveying track 12, the sliding seat 121 drives the hanging device 2 to move along the arc of the annular conveying track 12. At this time, the rectangular slider 215 immediately moves along the rounded corner of the rounded rectangular limiting groove 131 to the short side of the rounded rectangular limiting groove 131 under the pull of the rectangular limiting block 214. Since the width of the short side of the rounded rectangular limiting groove 131 The length of the rectangular slider 215 is the same as that of the rectangular slider 215. Therefore, when the rectangular slider 215 passes through the rounded corner and moves to the short side of the rounded rectangular limiting groove 131 and moves from the short side of the rounded rectangular limiting groove 131 to the long side of the other side, the length direction of the rectangular slider 215 does not change. Cooperating with the limiting of the rectangular limiting block 214 by the sliding groove 216, the plate fixed by the hanging device 2 does not flip during the movement. In this embodiment, due to the presence of the damping spring 217 in the sliding groove 216, the rectangular slider 215 can change the torque when moving at the rounded corner and the short side of the rounded rectangular limiting groove 131 by compressing the damping springs 217 at both ends. The position of the rectangular limit block 214 in the sliding groove 216 adapts to the movement of the sliding seat 121 in the arc section of the annular conveying track 12, ensuring that the rectangular limit block 214 provides a horizontal pulling force perpendicular to the straight section of the annular conveying track 12 to the rectangular slider 215, so that the rectangular slider 215 moves along the short side of the rounded rectangular limit groove 131, and the presence of the shock-absorbing spring 217 can buffer the inertia of the plate when it moves to the two ends of the annular conveying track 12 for changing direction, effectively preventing the position of the plate on the hanging device 2 from shifting, and avoiding the position of the secondary powder spraying from shifting and affecting the powder spraying effect.

[0042] In order to solve the problem of how to prevent the powder spray gun 3 from affecting the surface of the plate moving in the opposite direction, the following features are specifically set:

[0043] A partition plate 132 extending vertically downward is provided below the top plate 13 . The partition plate 132 is located on a side opposite to the output end of the powder spray gun 3 . The annular conveying track 12 drives the hanging device 2 to move on both sides of the partition plate 132 .

[0044] The partition 132 is located at the output end of the powder spraying gun 3 to block the powder output by the powder spraying gun 3 to prevent the subsequent plates from being affected by the plates that have been powder sprayed once. The partition 132 is located in the middle of the circular conveying track 12 and does not affect the movement of the sliding seat 121. The circular conveying track 12 drives the sliding seat 121 to drive the hanging device 2 to move around the partition 132. The side of the partition 132 away from the powder spraying gun 3 can be provided with a drying device and other subsequent processing steps. After the plate fixed by the hanging device 2 is subjected to secondary processing, the plate can be directly subjected to powder solidification and other processing steps by the drying device on the back of the partition 132 when passing through the back of the partition 132, thereby improving work efficiency. The devices with this function are all existing technologies, and the staff can set them according to actual needs, which are not shown in the figure.

[0045] In order to solve the problem of how to prevent the powder sprayed by the powder spray gun 3 from affecting the annular conveying track 12 on the base 11, the following features are specifically set:

[0046] A waist-shaped through hole 111 is provided on the base 11, and the annular conveying track 12 is located in the waist-shaped through hole 111 and moves. An elliptical plate 133 is provided at the bottom of the partition 132. The width between the outer wall of the elliptical plate 133 and the inner wall of the waist-shaped through hole 111 is not less than the diameter of the shaft rod 211. The shaft rod 211 moves in the waist-shaped limiting channel formed between the elliptical plate 133 and the waist-shaped through hole 111.

[0047] In this embodiment, the base 11 is provided with a waist-shaped through hole 111, and the annular conveying track 12 is installed in the waist-shaped through hole 111. The elliptical plate 133 at the bottom of the partition 132 is located above the annular conveying track 12 to block the annular conveying track 12. The shaft 211 below the mounting bracket 21 of the hanging device 2 is located in the waist-shaped limiting channel formed between the waist-shaped through hole 111 and the elliptical plate 133 and moves, that is, the moving path of the shaft 211 can be stabilized without affecting the rotation of the shaft 211. The waist-shaped through hole 111 and the elliptical plate 133 can block most of the powder sprayed by the powder spray gun 3. A rubber strip or a brush can be set on the side opposite to the waist-shaped through hole 111 and the elliptical plate 133 to block the powder from passing through the waist-shaped limiting channel without affecting the movement of the shaft 211. A powder-absorbing cleaning device can be set in the protective cover 4 to cooperate with the waist-shaped through hole 111 and the elliptical plate 133 to prevent the powder from falling into the annular conveying track 12 and affecting the movement of the sliding seat 121; the rubber strip or brush or cleaning device are all existing technologies and can achieve the purpose, and are not shown in the figure.

[0048] In order to solve the problem of how to realize that the hanging device 2 stably drives the large-sized plate to move, the following features are specifically set:

[0049] The top edge strips 22 are arranged horizontally, and at least two vertically extending guide rods 221 are arranged on the opposite side of the two top edge strips 22, and the guide rods 221 are inserted into the guide sleeves 218 arranged on the mounting bracket 21; a rack 222 parallel to the guide rod 221 is arranged on the top edge strips 22, and the racks 222 on the two top edge strips 22 are respectively meshed and connected to the two sides of the center gear 223, and the center gear 223 is rotatably installed at the center position of the mounting bracket 21. The mounting bracket 21 is also fixedly installed with a rotating driver 224, and the center gear 223 is transmission-connected to the working end of the rotating driver 224.

[0050] The top edge strip 22 is provided with a plurality of mounting holes penetrating the top edge strip 22 , and the vacuum suction cup 23 is fixedly mounted in the mounting holes on the top edge strip 22 , with the air inlet end of the vacuum suction cup 23 facing the side of the top edge strip 22 away from the mounting bracket 21 , and the vacuum suction cup 23 is connected to a vacuum generator 232 fixedly mounted on the mounting bracket 21 via an air pipe 231 .

[0051] The two top side strips 22 slidably mounted on the mounting bracket 21 of the hanging device 2 in this embodiment can fit the upper and lower side strips on the inner side of the plate to support the plate. The top side strips 22 are inserted into the guide sleeve 218 through the guide rod 221 to stabilize its moving path in the vertical direction. When the rotary driver 224 is started to drive the central gear 223 to rotate, the racks 222 from the two top side strips 22 meshing on both sides of the central gear 223 can be driven to move synchronously in the opposite direction, so that the top side strips 22 can support plates of any size. The rotary driver 224 can be a servo motor. The servo motor 224 can independently control the top edge bar 22 on a single mounting bracket 21 each time it rotates. When the moving range of the top edge bar 22 is smaller than the height of the plate to be fixed, the hanging device 2 can adsorb the inner wall of the plate through the vacuum suction cup 23 arranged in the mounting hole on the top edge bar 22, thereby keeping the hanging device 2 stable in a vertical state. The vacuum generator 232 that drives the vacuum suction cup 23 is installed on the mounting bracket 21 and moves synchronously with the mounting bracket 21, thereby achieving the fixation of larger-sized plates and improving the applicability of the equipment.

[0052] A powder spraying process for a battery energy storage box, applied to a powder spraying device for a battery energy storage box, comprises the following steps:

[0053] Step 1: Load the plate manually or by a robot arm, and the top edge strip 22 of the hanging device 2 cooperates with the vacuum suction cup 23 to fix the plate;

[0054] Step 2: The annular conveying track 12 is started to drive the hanging device 2 and the plate to move, and the powder spraying gun 3 performs powder spraying on the plate;

[0055] Step 3: The annular conveying track 12 drives the hanging device 2 and the plate to reset for secondary powder spraying processing;

[0056] Step 4: remove the powder-sprayed plate from the hanging device 2 for subsequent processing.

[0057] Working principle: When in use, the staff manually or automatically loads the plate using a robotic arm. The plate is mounted on the hanging device 2 that moves on the circular conveying track 12. Multiple plates are sequentially mounted on the hanging device 2 and follow the sliding seat 121 on the circular conveying track 12 to move through the working position of the powder spraying gun 3. The powder spraying gun 3 is connected to the working end of the linear drive. The powder spraying gun 3 reciprocates in the vertical direction to spray powder on the plate fixed by the hanging device 2. After the powder spraying gun 3 sprays powder, the circular conveying track 12 drives the hanging device 2 and the plate fixed by the hanging device 2 to move in the opposite direction to the loading position. When the sliding seat 121 moves to When the annular conveying track 12 is in the circular arc section, the limiting sleeve 212 and the fixed seat 213 of the hanging device 2 move and rotate with the sliding seat 121. At this time, the rectangular sliding block 215 on the top of the hanging device 2 cannot rotate in the rounded rectangular limiting groove 131 of the top plate 13, so that the mounting bracket 21 rotates around the axis of the shaft rod 211 in the limiting sleeve 212, and the plate on the hanging device 2 still remains facing the side of the powder spraying gun 3. The annular conveying track 12 drives the hanging device 2 and the plate fixed by the hanging device 2 to pass through the powder spraying gun 3 again for secondary powder spraying, and then is removed from the hanging device 2 for subsequent processing operations.

[0058] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
