Description

Technical Field

[0001] This invention relates to the field of energy storage box coating technology, and in particular to an energy storage box coating production line. Background Technology

[0002] In the energy storage equipment manufacturing industry, the energy storage tank is a core protective and load-bearing component. The quality of its surface coating directly determines the equipment's weather resistance, insulation, and service life. Energy storage tanks generally have a rectangular, three-dimensional structure, large volume, and numerous flat surfaces, posing many challenges to the coating process. Currently, the industry mainly uses two methods: manual coating and traditional machine coating.

[0003] When using manual spraying, the large size of the energy storage tank necessitates frequent movement of operators around the tank, using spraying tools to work on different areas. On one hand, prolonged standing, moving, and tool handling leads to extremely high labor intensity, easily causing operator fatigue and resulting in efficiency far below the requirements of mass production. On the other hand, manual operation is affected by subjective factors such as experience, physical strength, and attention, making it difficult to ensure uniform coating thickness across all areas, resulting in poor coating quality stability and requiring repeated inspections and touch-ups, further increasing labor costs.

[0004] When using machine spraying, existing machine spraying equipment, in order to simplify the structure, usually has spray nozzles fixed on both sides of the energy storage tank's conveyor track. When the energy storage tank is conveyed in a straight line, it can only perform directional spraying on the left and right sides of the tank. The front and rear sides are in the blind spot of the spray nozzle coverage. To complete the full surface spraying, it is necessary to rotate the tank by 90° through a complex conveyor track linkage mechanism, so that the front and rear sides face the direction of the spray nozzle. This process not only requires additional rotary drive components, but also increases equipment costs. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes an energy storage box coating production line.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An energy storage tank coating production line includes a rectangular track frame with two U-shaped tracks symmetrically arranged front to back. A slider seat is slidably mounted on each U-shaped track. A rotating disk is rotatably mounted on the lower end of each slider seat. A vertical post is mounted on the lower end of the rotating disk, and several nozzle assemblies are evenly distributed vertically on the vertical post. An elastic positioning component is provided between the slider seat and the rotating disk to elastically fix the rotating disk. A power drive device is also provided on the rectangular track frame, which can simultaneously drive the two slider seats to move back and forth along each U-shaped track. The area below the rectangular track frame is the coating area. An adjustment device is also provided on the rectangular track frame. When the slider seat moves within the U-shaped track, the adjustment device can drive the rotating disk to rotate, thereby keeping the nozzle assemblies facing the coating area.

[0008] In some embodiments, the U-shaped track includes a transverse track extending in a left-right direction and vertical tracks disposed at both ends of the transverse track.

[0009] In some embodiments, the slider seat includes a slider that is slidably disposed in a U-shaped track, an upper seat body disposed at the upper end of the slider, and a lower seat body disposed at the lower end of the slider. The upper seat body is connected to a power drive device, and the lower seat body is connected to a rotary disk.

[0010] In some embodiments, the power drive device includes a linear screw module disposed on the upper end of the rectangular track frame. The linear screw module is provided with a screw sleeve seat that slides in the left-right direction. A hinge rod is hinged to the upper seat body, and the other end of the hinge rod is hinged to the screw sleeve seat. When the screw sleeve seat slides, the hinge rod can push the slider seat to move along the vertical track. A locking device is also provided on the screw sleeve seat. When the slider seat moves to the horizontal track end, the hinge rod is parallel to the vertical track. At this time, the locking device can lock the hinge rod to the screw sleeve seat.

[0011] In some embodiments, the locking device includes a locking hole on the hinge rod, a support frame on the lead screw sleeve seat, a first cylinder on the support frame, the piston rod of the first cylinder pointing vertically downward and having a horizontal plate, and insert rods that can be inserted into the locking hole at both ends of the horizontal plate.

[0012] In some embodiments, the elastic positioning component includes a groove at the lower end of the lower seat, a spring and a positioning steel ball are disposed in the groove, and a plurality of positioning grooves that cooperate with the positioning steel balls are evenly distributed along the circumference at the upper end of the rotating disk.

[0013] In some embodiments, the adjusting device includes rack holders spaced apart at both ends of the transverse track, a rack is provided on the rack holders, and a gear that can mesh with the rack is provided on the rotating disk. When the slider seat moves on the transverse track, the gear can mesh with the rack.

[0014] In some embodiments, the nozzle assembly includes a swing rod that swings up and down on the upright, with a nozzle at one end of the swing rod, and a swing mechanism that can drive the swing rod to swing up and down is also provided on the upright.

[0015] In some embodiments, the swing mechanism includes a cylinder fixing plate disposed on one side of the rotating disk, a second cylinder disposed on the cylinder fixing plate, a vertically downward adjusting rod disposed on the piston rod of the second cylinder, a lever disposed on the adjusting rod corresponding to the swing rod, a guide groove disposed at the end of the swing rod away from the nozzle, and each lever disposed in the guide groove.

[0016] In some embodiments, the opening edge of the locking hole and the lower edge of the insertion rod are both beveled.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The production line achieves fully automatic movement and direction adjustment of the spray nozzle assembly through a power drive device and automated track structure. Operators are not required to hold tools and work around the box, which completely replaces the traditional manual spraying mode, thereby greatly reducing labor intensity and improving efficiency.

[0019] 2. The rectangular track frame features two symmetrically distributed U-shaped tracks. As the slider slides along the tracks, it covers the left, right, front, and rear areas of the energy storage tank. Simultaneously, the adjustment device drives the rotating disk to rotate during the slider's movement, ensuring that the spray nozzle assembly on the upright always faces the spraying area. This design completely eliminates the blind spots on the front and rear sides of traditional machine spraying, eliminates the need for additional tank rotation mechanisms and manual touch-ups, and achieves one-pass full-surface spraying of the rectangular three-dimensional energy storage tank, significantly improving the consistency of appearance and protective performance.

[0020] 3. The elastic positioning component between the slider seat and the rotary table can quickly and elastically reset and lock the angle after the rotary table is adjusted in direction, ensuring that the nozzle is always accurately aligned with the spraying area, greatly reducing rework and material waste caused by positioning deviation.

[0030] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0031] like Figures 1-9The energy storage tank coating production line shown includes a rectangular track frame 1. The rectangular track frame 1 includes two U-shaped tracks 2 symmetrically arranged front to back. Each U-shaped track 2 includes a horizontal track 21 extending in a left-right direction and vertical tracks 22 located at both ends of the horizontal track 21. Sliding slider seats 3 are slidably mounted on both U-shaped tracks 2. A rotating disk 4 is rotatably mounted on the lower end of each sliding slider seat 3. A vertical rod 5 is provided at the lower end of the rotating disk 4. Several spray head assemblies are evenly distributed vertically on the vertical rod 5. Between the sliding slider seat 3 and the rotating disk 4... An elastic positioning component is provided to elastically fix the rotating disk 4. A power drive device is also provided on the rectangular track frame 1. The power drive device can simultaneously drive the two slider seats 3 to move back and forth along each U-shaped track 2. The lower part of the rectangular track frame 1 is the spraying area. An adjustment device is also provided on the rectangular track frame 1. When the slider seat 3 moves in the U-shaped track 2, it can drive the rotating disk 4 to rotate through the adjustment device, so that its nozzle assembly is kept facing the spraying area.

[0032] First, the energy storage box 10 to be sprayed is transported to the spraying area below the rectangular track frame 1 via the conveyor line 11. After the equipment is started, the power drive device on the rectangular track frame 1 begins to work, which synchronously drives the slider seats 3 on the two U-shaped tracks 2 to move back and forth along the tracks. Due to the structural characteristics of the U-shaped tracks 2, the movement trajectory of the slider seats 3 is "U" shaped, which can cover the left and right sides and the front and rear outer areas of the box in the spraying area. When the slider seats 3 move along the transverse track 21 of the U-shaped track 2, they correspond to the left and right side surfaces of the box; when the slider seats move along the longitudinal track 22 of the U-shaped track 2, they correspond to the front and rear side surfaces of the box, achieving full coverage of the four sides of the box.

[0033] As the slider seat 3 moves along the U-shaped track 2, the adjustment device on the rectangular track frame 1 is linked to the movement of the slider seat 3 in real time. When the slider seat 3 moves from the transverse section to the longitudinal section of the U-shaped track 2 (or vice versa), the adjustment device drives the rotating disk 4 at the lower end of the slider seat 3 to rotate at the corresponding angle via mechanical transmission. When the rotating disk 4 rotates, the upright 5 connected to its lower end and the nozzle assembly on the upright rotate synchronously, always keeping the spraying direction of the nozzle assembly facing the surface of the energy storage box in the spraying area. Even if the slider seat changes its moving direction, the nozzle will not deviate from the spraying direction due to the track turning, ensuring that each facade of the box can be accurately aligned by the nozzle.

[0034] When the rotating disk 4 is rotated to adjust its direction, after the rotating disk 4 is adjusted to the target angle, the elastic positioning component can quickly and elastically reset and reliably fix the rotating disk, lock the nozzle direction, prevent the rotating disk from rotating unexpectedly during the spraying process, and ensure the coating thickness and uniformity.

[0035] Furthermore, the slider seat 3 includes a slider 31 that is slidably disposed in the U-shaped track 2, an upper seat body 32 disposed at the upper end of the slider 31, and a lower seat body 33 disposed at the lower end of the slider 31. The upper seat body 32 is connected to the power drive device, and the lower seat body 33 is connected to the rotating disk 4.

[0036] During the equipment assembly phase, the various components of the slider seat 3 are precisely assembled. The slider 31 slides into the track groove of the U-shaped track 2, with its outer circumference fitting against the inner wall of the track groove to ensure stability during sliding. The upper end of the slider 31 is fixedly connected to the upper seat body 32, which is connected to the power drive device on the rectangular track frame 1 to form a power transmission path. The lower end of the slider 31 is fixedly connected to the lower seat body 33, which is rotatably connected to the rotating disk 4 through bearings, ensuring that the rotating disk can rotate flexibly around the axis of the lower seat body.

[0037] In this invention, the power drive device includes a linear lead screw module 41 disposed on the upper end of the rectangular track frame 1. The linear lead screw module 41 is provided with a lead screw sleeve seat 42 that slides in the left and right direction. A hinge rod 43 is hinged to the upper seat 32. The other end of the hinge rod 43 is hinged to the lead screw sleeve seat 42. When the lead screw sleeve seat 42 slides, the hinge rod 43 can push the slider seat 3 to move along the vertical track 22. A locking device is also provided on the lead screw sleeve seat 42. When the slider seat 3 moves to the end of the horizontal track 21, the hinge rod 43 is parallel to the vertical track 22. At this time, the locking device can lock the hinge rod 43 to the lead screw sleeve seat 42.

[0038] Specifically, during the equipment assembly stage, the power drive device completes the connection with the rectangular track frame 1 and the slider seat 3. The linear lead screw module 41 is horizontally fixed to the upper end of the rectangular track frame 1, and its extension direction is consistent with the transverse track 21 (along the left and right direction); the lead screw sleeve seat 42 engages with the lead screw of the linear lead screw module 41 through internal threads and can slide left and right along the lead screw; the upper seat 32 and the lead screw sleeve seat 42 are connected by a hinge rod 43, and the two ends of the hinge rod 43 form a rotatable hinge structure with the upper seat 32 and the lead screw sleeve seat 42 respectively, ensuring that the three can rotate relative to each other; the locking device is installed on the lead screw sleeve seat 42, and its locking end corresponds to the end face of the hinge rod 43. In the initial state, the locking device is in the unlocked state, and the hinge rod can rotate freely.

[0039] When the equipment is in the spraying stage on the vertical track 22, the drive motor of the linear lead screw module 41 starts, causing the lead screw to rotate around its own axis. Since the lead screw sleeve 42 engages with the lead screw, the rotation of the lead screw is converted into the left and right sliding of the lead screw sleeve along the lead screw. At this time, the sliding of the lead screw sleeve 42 is transmitted to the upper seat 32 through the hinge rod 43. One end of the hinge rod 43 moves left and right with the lead screw sleeve, while the other end pushes or pulls the upper seat 32 to move along the extension direction of the vertical track 22. For example, see... Figure 2 As shown, when the lead screw slide sleeve seat slides to the right, the hinge rod 43 pushes the two upper seats 32 on the front and rear sides to move along the vertical track 22 respectively. During this process, the lower seat 33, the rotating disk 4, and the spray head assembly move together to complete the spraying of the front surface of the box.

[0040] When the slider seat 3 moves along the vertical track 22 to the end of the horizontal track 21, the lead screw sleeve seat 42 slides synchronously to the preset position along with the slider seat. At this time, the extension direction of the hinge rod 43 is completely parallel to the vertical track 22. After the control system detects this position signal, it triggers the locking device on the lead screw sleeve seat 42 to start: the locking end of the locking device extends and clamps the hinge rod 43, fixing the hinge rod and the lead screw sleeve seat 42 as one unit, restricting the relative rotation between the two. At this time, the hinge rod 43 is in a rigid fixed state. The subsequent sliding of the lead screw sleeve seat along the linear lead screw module will no longer drive the slider seat to move vertically through the hinge rod, but will instead drive the entire slider seat to move along the extension direction of the horizontal track 21 with the hinge rod, realizing a smooth switch from the vertical track to the horizontal track.

[0041] Slider seat 3 completes the left and right spraying along the transverse track 21 (e.g.) Figure 4 As shown), the left and right surfaces of the housing are sprayed. When the slider seat 3 moves to the rightmost port of the horizontal track, the control system sends an unlocking signal, the locking end of the locking device retracts, releasing the fixation of the hinge rod 43, and the hinge rod returns to a free rotation state. Subsequently, the linear screw module 41 continues to drive the screw sleeve seat to slide to the right, and through the hinge rod 43, it drives the slider seat 3 to move up and down along the vertical track 22 again (as shown). Figure 7 As shown in the image, the spraying of the rear surface of the housing is completed. Then, the next vertical spraying cycle begins.

[0042] It should be noted that when the slider seat 3 moves from the vertical track 22 into the horizontal track 21, or from the horizontal track 21 into the vertical track 22, the rotating disk 4 will be rotated at a corresponding angle by the adjustment device, so as to always keep the spraying direction of the nozzle assembly facing the surface of the energy storage box in the spraying area.

[0043] Furthermore, the locking device includes a locking hole 50 on the hinge rod 43, a support frame 51 on the lead screw slide seat 42, a first cylinder 52 on the support frame 51, the piston rod of the first cylinder 52 is vertically downward and a horizontal plate 53 is provided, and insert rods 54 that can be inserted into the locking hole 50 are provided at both ends of the horizontal plate 53.

[0044] When the slider seat 3 moves along the vertical track 22 to the end of the horizontal track 21, and the hinge rod 43 moves with the lead screw sleeve seat 42 to a position completely parallel to the vertical track 22, the control system detects this status signal through the position sensor and then sends an extension command to the first cylinder 52. After receiving the command, the first cylinder 52 drives the piston rod to extend vertically downward, causing the horizontal plate 53 to move downward synchronously. The insert rods 54 at both ends of the horizontal plate 53 move downward together with the horizontal plate. Since the insert rods 54 are completely aligned with the locking holes 50 on the hinge rod 43 at this time, the insert rods 54 will be precisely inserted into the locking holes 50. At this time, the insert rods 54 fix the hinge rod 43 and the lead screw sleeve seat 42 into one piece through the locking holes 50, restricting the relative rotation between the two. The hinge rod 43 enters a rigid fixed state, preparing for the subsequent movement of the slider seat 3 along the horizontal track 21.

[0045] To facilitate the insertion of the rod 54 into the locking hole 50, the opening edge of the locking hole 50 and the lower edge of the rod 54 are both beveled.

[0046] See Figure 9 As shown, the elastic positioning component includes a groove 61 located at the lower end of the lower seat 33, a spring 62 and a positioning steel ball 63 are provided in the groove 61, and a plurality of positioning grooves 64 that cooperate with the positioning steel ball 63 are evenly distributed along the circumference at the upper end of the rotating disk 4.

[0047] When the adjusting device drives the rotating disk 4 to rotate, the rotating disk 4 is subjected to an external force, and a relative sliding friction force is generated between the positioning groove 64 on its upper end surface and the positioning steel ball 63. This friction force is greater than the elastic thrust of the spring 62 on the positioning steel ball 63, pushing the positioning steel ball 63 to overcome the spring force and compress the spring 62 downwards, gradually dislodging it from the current positioning groove 64 and entering the smooth area on the upper end surface of the rotating disk 4. At this time, the elastic positioning component releases the fixation of the rotating disk 4, and the rotating disk can rotate freely under the drive of the adjusting device. The positioning steel ball 63 slides tightly against the upper end surface of the rotating disk under the action of the spring force, continuously preparing for subsequent positioning.

[0048] When the rotating disk 4 rotates to the target angle under the drive of the adjusting device, the next positioning groove 64 on the upper surface of the rotating disk 4 rotates to the position corresponding to the positioning steel ball 63. At this time, the sliding friction force on the positioning steel ball 63 disappears, and the spring 62 extends upward under the action of elastic restoring force, pushing the positioning steel ball 63 to re-embed into the positioning groove 64. The positioning steel ball 63 and the arc-shaped surface of the positioning groove 64 fit tightly together, forming a reliable elastic positioning, which again restricts the rotation of the rotating disk 4 and ensures that the rotating disk is stably maintained at the target angle. At the same time, the continuous elastic thrust of the spring keeps the steel ball and the groove in close contact at all times. Even if the equipment vibrates slightly during operation, it can prevent the rotating disk from deviating at an angle, providing a stable guarantee for the precise alignment of the spray head assembly with the spraying area.

[0049] See Figures 2-7 As shown, the adjustment device includes a rack fixing frame 71 spaced at both ends of the transverse track 21, a rack 72 is provided on the rack fixing frame 71, and a gear 73 that can mesh with the rack 72 is provided on the rotating disk 4. When the slider seat 3 moves on the transverse track 21, the gear 73 can mesh with the rack 72.

[0050] When the power drive device moves the slider seat 3 along the transverse track 21 (soon to switch phase), the rotating disk 4, which moves synchronously with the slider seat, also approaches the rack and pinion bracket 71 of the transverse track. When the slider seat 3 moves to a preset distance from the end of the transverse track, the gear 73 on the rotating disk 4 begins to contact and gradually mesh with the rack 72 on the rack and pinion bracket 71. Since the rack 72 is fixed, the movement of the slider seat causes the gear 73 to roll along the length of the rack. The teeth of the gear and the rack mesh with each other, converting the linear movement of the slider seat into the rotational motion of the gear. As the slider seat 3 continues to move along the transverse track 21, the meshing depth of the gear 73 and the rack 72 gradually increases. The fixed teeth of the rack continuously apply a circumferential force to the teeth of the gear, driving the gear 73 to rotate around the axis of the rotating disk 4. Since the gear and the rotating disk are coaxially fixed, the rotating disk 4 rotates synchronously with the gear.

[0051] It should be noted that the number of teeth on rack 72 can be set according to the required rotation angle.

[0052] See Figure 5 , Figure 6As shown, the nozzle assembly includes a swing rod 81 that swings up and down on the upright 5. One end of the swing rod 81 is provided with a nozzle 82. The upright 5 is also provided with a swing mechanism that can drive the swing rod 81 to swing up and down. The swing mechanism includes a cylinder fixing plate 91 provided on one side of the rotating disk 4. A second cylinder 92 is provided on the cylinder fixing plate 91. A vertically downward adjusting rod 93 is provided on the piston rod of the second cylinder 92. A lever 94 corresponding to the swing rod 81 is provided on the adjusting rod 93. A guide groove 95 is provided at the end of the swing rod 81 away from the nozzle 82. Each lever 94 is correspondingly provided in the guide groove 95.

[0053] When the power drive unit moves the slider seat 3 along the U-shaped track 2, the control system synchronously sends a reciprocating motion command to the second cylinder 92 to start the swing mechanism. After receiving the command, the second cylinder 92 drives the adjusting rod 93 to move up and down reciprocally through the piston rod. The lever 94 on the adjusting rod 93 slides in the guide groove 95 on the swing rod 81, generating a longitudinal thrust on the inner wall of the groove, thereby driving the swing rod 81 to swing up and down (lever principle). The swing rod 81 swings up and down continuously, and the nozzle 82 forms a continuous up and down swinging spraying trajectory, which greatly improves the spraying effect.
