Description

Technical Field

[0001] This application relates to the field of spraying technology, and in particular to a spraying device. Background Technology

[0002] In battery cell production, the surface coating process is crucial for ensuring the insulation, pressure resistance, and corrosion resistance of the cells, directly affecting the safety and service life of the finished product. Currently, the industry commonly uses automated track conveyor systems to transport battery cell coating fixtures. A track drive mechanism moves the fixture carrying the battery cells along a preset path, and the fixture must precisely stop at the processing station to ensure that the processing equipment operates according to preset parameters.

[0003] However, in actual production, due to factors such as deviations in track assembly accuracy, wear and tear between the fixture and the track, vibration of the conveying power mechanism, and uneven loading weight of the battery cells, after the fixture is delivered to its position, displacement deviations often occur along the length or width of the track, resulting in the fixture and the workstation reference positioning surface not fitting precisely. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a spraying device that can solve the problem that the fixture and the station reference positioning surface of the existing spraying device cannot be accurately aligned.

[0005] To address the aforementioned technical problems, this application discloses a spraying device, comprising:

[0006] The track has a first positioning part on one side;

[0007] A fixture is movable within the track, and the fixture is provided with a second positioning part at a position facing the other side of the track;

[0008] A first positioning mechanism, located on the other side of the track, is movable to abut against the fixture, so that the first positioning mechanism and the first positioning part together restrict the position of the fixture along the width direction of the track; and

[0009] The second positioning mechanism is located on the other side of the track and can be moved to cooperate with the second positioning part to limit the position of the fixture along the length of the track.

[0010] As an optional implementation, in this embodiment of the application, the fixture is provided with a first plane corresponding to the position of the first positioning mechanism. The first plane is parallel to the first positioning part. The side of the first positioning mechanism facing the fixture is provided with a second plane corresponding to the first plane. When the first positioning mechanism abuts against the fixture, the second plane fits against the first plane.

[0011] As an optional implementation, in this embodiment of the application, the first positioning mechanism includes a first drive motor and a first positioning block. The first drive motor is located on the other side of the track, and the first positioning block is connected to the first drive motor. The first drive motor is used to drive the first positioning block to move along the direction close to the fixture to abut against the fixture, or to move along the direction away from the fixture to separate from the fixture.

[0012] As an optional implementation, in this embodiment of the application, the second positioning part is a V-shaped groove with an opening facing the second positioning mechanism, and the second positioning mechanism is provided with a V-shaped block protruding towards the fixture. When the second positioning mechanism cooperates with the second positioning part, the V-shaped block is embedded in the V-shaped groove.

[0013] As an optional implementation, in this embodiment of the application, the second positioning mechanism includes a second drive motor and a second positioning block. The second drive motor is located on the other side of the track, and the second positioning block is connected to the second drive motor. The second drive motor is used to drive the second positioning block to move along the direction close to the fixture to cooperate with the second positioning part, or to move along the direction away from the fixture to separate from the second positioning part.

[0014] As an optional implementation, in this embodiment of the application, the fixture can move within the track along a first direction, and the spraying equipment further includes a check mechanism, which is used to abut against the fixture when the fixture is located within the track to prevent the fixture from moving back in a direction opposite to the first direction.

[0015] As an optional implementation, in this embodiment of the application, the anti-return mechanism includes a rotating shaft, an elastic element, and a limiting block. The rotating shaft and the elastic element are both located on the other side of the track. The limiting block is rotatably mounted on the rotating shaft, and the elastic element is connected to the end of the limiting block that is away from the fixture.

[0016] When the fixture is in the track, the other end of the limiting block rotates under the push of the fixture to tilt and abut against the fixture, and the elastic element is stretched under the action of the limiting block;

[0017] When the fixture is not in the track, the elastic element retracts and pulls one end of the limiting block, while the other end of the limiting block rotates to extend into the track.

[0018] As an optional implementation, in this embodiment of the application, the track includes an infeed station, a processing station and an outfeed station arranged sequentially along the first direction. The fixture is also provided with a positioning groove corresponding to the processing station. When the fixture is located at the infeed station and the outfeed station, the other end of the limiting block abuts against the side wall of the fixture. When the fixture is located at the processing station, the other end of the limiting block is engaged in the positioning groove.

[0019] As an optional implementation, in this embodiment of the application, the track includes an infeed station, a processing station, and an outfeed station arranged sequentially along the first direction. One end of the limiting block is provided with a sensing plate. The spraying equipment also includes a first sensor and a second sensor. The first sensor and the second sensor are spaced apart on the other side of the track. When the fixture is located at the infeed station and the outfeed station, the sensing plate is located in the sensing area of ​​the first sensor. When the fixture is located at the processing station, the sensing plate is located in the sensing area of ​​the second sensor.

[0020] As an optional implementation, in this embodiment of the application, the other end of the limiting block is provided with a pulley, and the pulley slides against the fixture.

[0021] Compared to existing technologies, this application provides a spraying device including a track, a fixture, a first positioning mechanism, and a second positioning mechanism. A first positioning part is provided on one side of the track, allowing the fixture to move within the track. A second positioning part is provided on the fixture facing the other side of the track. The first positioning mechanism is located on the other side of the track and can move to abut against the fixture, so that the first positioning mechanism and the first positioning part together restrict the position of the fixture along the width direction of the track. The second positioning mechanism is located on the other side of the track and can move to cooperate with the second positioning part to restrict the position of the fixture along the length direction of the track. With this design, the first positioning mechanism and the first positioning part cooperate to position the fixture in the width direction, and the second positioning mechanism and the second positioning part cooperate to position the fixture in the length direction, thereby ensuring that the fixture accurately conforms to the workstation reference.

It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application. Unless further described, elements, structures, and features in one embodiment may be advantageously combined with other embodiments.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0030] The terms "length," "width," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to constitute an infringement.

[0031] The instruction or implication refers to a device or component that must have a specific orientation, be constructed and operated in a specific orientation.

[0032] Please refer to the following: Figures 1 to 4As shown, the spraying equipment provided in this application includes a track 10, a fixture 20, a first positioning mechanism 30, and a second positioning mechanism 40. A first positioning part 11 is provided on one side of the track 10. The fixture 20 can move within the track 10. A second positioning part 21 is provided on the fixture 20 facing the other side of the track 10. The first positioning mechanism 30 is located on the other side of the track 10 and can move to abut against the fixture 20, so that the first positioning mechanism 30 and the first positioning part 11 together restrict the fixture 20 along the width direction of the track 10 (e.g., ...). Figure 2 The position of the fixture 20 (as shown in the middle x); and the second positioning mechanism 40 is located on the other side of the track 10 and can be moved to cooperate with the second positioning part 21 to limit the fixture 20 along the length direction of the track 10 (as shown in the middle x). Figure 2 The position is shown in y1. With this design, the first positioning mechanism 30 and the first positioning part 11 cooperate to position the width of the fixture 20, and the second positioning mechanism 40 and the second positioning part 21 cooperate to position the length of the fixture 20, thereby ensuring that the fixture 20 accurately fits the work station reference.

[0033] In some embodiments, the fixture 20 has a first plane 22 corresponding to the position of the first positioning mechanism 30. The first plane 22 is parallel to the first positioning part 11. The side of the first positioning mechanism 30 facing the fixture 20 has a second plane 321 corresponding to the first plane 22. When the first positioning mechanism 30 abuts against the fixture 20, the second plane 321 fits against the first plane 22. With this design, during positioning, the first positioning mechanism 30 moves until the second plane 321 fits against the first plane 22, which is equivalent to the second plane 321 being parallel to the first positioning part 11. The two planes clamp the two sides of the fixture 20, thereby better restricting its position along the width direction of the track 10.

[0034] In some embodiments, in order for the first positioning mechanism 30 to move to abut against the fixture 20, the first positioning mechanism 30 includes a first drive motor 31 and a first positioning block 32. The first drive motor 31 is located on the other side of the track 10, and the first positioning block 32 is connected to the first drive motor 31. The first drive motor 31 is used to drive the first positioning block 32 to move in a direction close to the fixture 20 to abut against the fixture 20, or to move in a direction away from the fixture 20 to separate from the fixture 20. With this design, when the fixture 20 needs to be positioned, the first positioning block 32 can move under the drive of the first drive motor 31 to abut against the fixture 20; when the fixture 20 does not need to be positioned, the first positioning block 32 can move under the drive of the first drive motor 31 to separate from the fixture 20, thereby avoiding interference with the movement of the fixture 20 on the track 10.

[0035] In some embodiments, in order for the second positioning mechanism 40 to cooperate with the second positioning part 21 to limit the position of the fixture 20 along the length direction of the track 10, the second positioning part 21 is a V-shaped groove with an opening facing the second positioning mechanism 40, and the second positioning mechanism 40 is provided with a V-shaped block 421 protruding towards the fixture 20. When the second positioning mechanism 40 cooperates with the second positioning part 21, the V-shaped block 421 is embedded in the V-shaped groove.

[0036] In some embodiments, in order for the second positioning mechanism 40 to move to engage with the second positioning part 21, the second positioning mechanism 40 includes a second drive motor 41 and a second positioning block 42. The second drive motor 41 is located on the other side of the track 10, and the second positioning block 42 is connected to the second drive motor 41. The second drive motor 41 is used to drive the second positioning block 42 to move in a direction close to the fixture 20 to engage with the second positioning part 21, or to move in a direction away from the fixture 20 to separate from the second positioning part 21. With this design, when the fixture 20 needs to be positioned, the second positioning block 42 can move under the drive of the second drive motor 41 to engage with the second positioning part 21; when the fixture 20 does not need to be positioned, the second positioning block 42 can move under the drive of the second drive motor 41 to separate from the second positioning part 21, thereby avoiding interference with the movement of the fixture 20 on the track 10.

[0037] like Figure 5 As shown, in some embodiments, to prevent the jig 20 from moving back within the track 10, the jig 20 may move within the track 10 along a first direction (e.g., Figure 2 As shown in Figure 2, the spraying equipment also includes a check mechanism, which abuts against the fixture 20 when the fixture 20 is within the track 10 to prevent the fixture 20 from moving back in a direction opposite to the first direction. With this design, the check mechanism abuts against the fixture 20, preventing the fixture 20 from moving in the opposite direction.

[0038] Furthermore, the check mechanism includes a rotating shaft 51, an elastic element 52, and a limiting block 53. The rotating shaft 51 and the elastic element 52 are both located on the other side of the track 10. The limiting block 53 is rotatably mounted on the rotating shaft 51. The elastic element 52 is connected to the end of the limiting block 53 that is away from the fixture 20. When the fixture 20 is within the track 10, the other end of the limiting block 53 rotates under the push of the fixture 20 to tilt and abut against the fixture 20. The elastic element 52 is stretched under the action of the limiting block 53. The retraction force of the elastic element 52 acts on one end of the limiting block 53, so that the other end of the limiting block 53 abuts tightly against the fixture 20. When the fixture 20 is not within the track 10, the elastic element 52 retracts and pulls one end of the limiting block 53, and the other end of the limiting block 53 rotates to extend into the track 10.

[0039] Preferably, the other end of the limiting block 53 is provided with a pulley 54, which slides against the fixture 20. With this design, the friction between the limiting block 53 and the fixture 20 can be reduced because the end of the limiting block 53 is provided with a pulley 54.

[0040] In some embodiments, the track 10 includes an entry station, a processing station and an exit station arranged sequentially along a first direction. The fixture 20 enters the processing station from the entry station, is positioned at the processing station to process the battery cell on the fixture 20, and then exits from the exit station after processing is completed.

[0041] The fixture 20 is also equipped with a positioning groove 23 corresponding to the machining station. When the fixture 20 is located at the moving-in station and the moving-out station, the other end of the limiting block 53 abuts against the side wall of the fixture 20. When the fixture 20 is located at the machining station, the other end of the limiting block 53 is engaged in the positioning groove 23. This design makes the positioning effect of the fixture 20 better at the machining station.

[0042] Furthermore, considering the need to check whether the fixture 20 is in the processing position when restarting the spraying equipment after an abnormal shutdown, a sensing element 60 is provided at one end of the limit block 53. The spraying equipment also includes a first sensor 70 and a second sensor 80, which are spaced apart on the other side of the track 10. When the fixture 20 is in the infeed or outfeed position, the sensing element 60 is located within the sensing area of ​​the first sensor 70, allowing the first sensor 70 to send information about the fixture 20 being in an inaccurate position within the track 10 to the control system. When the fixture 20 is in the processing position, the sensing element 60 is located within the sensing area of ​​the second sensor 80, allowing the second sensor 80 to send information about the fixture 20 being in the correct position within the track 10 to the control system. Additionally, if neither the first sensor 70 nor the second sensor 80 sends any feedback, it indicates that the fixture 20 has not been detected.

[0043] Among them, the sensing sheet 60 is a photoelectric sensing sheet 60, and the first sensor 70 and the second sensor 80 are both photoelectric sensors.

[0044] This application provides a spraying device including a track 10, a fixture 20, a first positioning mechanism 30, and a second positioning mechanism 40. A first positioning part 11 is provided on one side of the track 10, and the fixture 20 can move within the track 10. A second positioning part 21 is provided on the fixture 20 facing the other side of the track 10. The first positioning mechanism 30 is located on the other side of the track 10 and can move to abut against the fixture 20, so that the first positioning mechanism 30 and the first positioning part 11 jointly restrict the position of the fixture 20 along the width direction of the track 10. The second positioning mechanism 40 is located on the other side of the track 10 and can move to cooperate with the second positioning part 21 to restrict the position of the fixture 20 along the length direction of the track 10. With this design, the first positioning mechanism 30 cooperates with the first positioning part 11 to position the fixture 20 in the width direction, and the second positioning mechanism 40 cooperates with the second positioning part 21 to position the fixture 20 in the length direction, thereby ensuring that the fixture 20 accurately conforms to the workstation reference.
