[0035] Please see Figure 1 The production equipment provided in this application is used to apply fluid to the surface of workpiece 40 by spraying technology. The production equipment includes a main body, a conveying track 50 and a fixture 10. The conveying track 50 is provided with spraying stations 20 and curing stations 30 at intervals. The fixture 10 is movably disposed on the conveying track 50. The fixture 10 can be conveyed from the spraying station 20 to the curing station 30 by a toggle. When the fixture 10 moves to the spraying station 20, it is positioned at the spraying station 20 for spraying. When the fixture 10 moves to the curing station 30, it is cured while moving.

[0036] Please refer to the following: Figure 2 and Figure 5 The fixture 10 is used to position the workpiece 40 and move it between the spraying station 20 and the curing station 30 to facilitate the spraying of fluid onto the surface of the workpiece 40. The fixture 10 includes a base 11, multiple positioning components 12, and a transmission mechanism. The multiple positioning components 12 are rotatably mounted on the base 11 to position the workpiece 40 one by one. The transmission mechanism is located on the base 11 and connected to the multiple positioning components 12. The transmission mechanism is used to cooperate with the drive mechanism of the production equipment to drive the multiple positioning components 12 to rotate, thereby driving the multiple workpieces 40 to rotate. The production equipment is a spraying production equipment. After the fixture 10 is positioned at the spraying station 20, it performs spraying. It moves and cures at the curing station 30. The workpiece 40 that the fixture 10 is used to hold is a battery cell. The fixture 10 moves between the spraying station 20 and the curing station 30 of the spraying production equipment so that the battery cell can complete the spraying process on the spraying production line. This design, through the cooperation of the transmission mechanism and the drive mechanism, can drive the battery cell to rotate during the spraying process, thereby improving the spraying efficiency and quality of the battery cell.

[0037] The positioning component 12 can be an adsorption component or a clamping component, etc., and is not limited to it here.

[0038] In some embodiments, in order for the transmission mechanism to better transmit power between the drive mechanism and the multiple positioning components 12, the transmission mechanism may include a first gear 131 and a transmission component 132. The first gear 131 is rotatably mounted on the base 11, and the transmission component 132 is rotatably mounted on the base 11 and connected to the first gear 131. The multiple positioning components 12 are connected to the transmission component 132. The first gear 131 is used to cooperate with the drive mechanism of the production equipment to drive the transmission component 132, so that the transmission component 132 drives the multiple positioning components 12.

[0039] In order to realize the installation of the first gear 131, the transmission component 132 and the multiple positioning components 12 on the base 11, the base 11 may include a base plate 111 and a mounting bracket 112. The first gear 131 is rotatably disposed at the bottom of the base plate 111, the transmission component 132 is located at the top of the base plate 111 and passes through the base plate 111 to be connected to the first gear 131, the mounting bracket 112 covers the transmission component 132, the transmission component 132 is rotatably connected to the mounting bracket 112, and the multiple positioning components 12 are rotatably disposed on the mounting bracket 112.

[0040] Furthermore, the base 11 has an elongated structure, with multiple positioning components 12 arranged sequentially along the length of the base 11. The first gear 131 is located in the middle of the base 11. There are two transmission components 132 arranged symmetrically about the first gear 131. The multiple positioning components 12 located on one side of the first gear 131 are connected to the transmission component 132 located on the same side as the first gear 131, and the multiple positioning components 12 located on the other side of the first gear 131 are also connected to the transmission component 132 located on the other side of the first gear 131. That is, the first gear 131 drives the two transmission components 132 to rotate, and the two transmission components 132 then drive the multiple positioning components 12 to rotate respectively.

[0041] Furthermore, in order to simultaneously drive multiple positioning components 12, the transmission component 132 may include a toothed transmission belt 1322 and multiple second gears 1321. The multiple second gears 1321 are rotatably mounted on the base 11, and the toothed transmission belt 1322 is wound around the outer periphery of the multiple second gears 1321 and meshes with them. One of the second gears 1321 is coaxially connected to the first gear 131, and the multiple positioning components 12 are correspondingly connected to and coaxially arranged with the corresponding second gear 1321. With this design, since one of the second gears 1321 is coaxially arranged with the first gear 131, the second gear 1321 rotates under the drive of the first gear 131, which on the one hand drives the positioning component 12 connected to it and coaxially arranged to rotate, and on the other hand drives the toothed transmission belt 1322 to drive the other second gears 1321 to rotate, thereby causing the other second gears 1321 to drive the positioning component 12 to rotate.

[0042] It is understood that, in addition to the gear + toothed belt transmission method exemplified in this embodiment, the transmission component 132 can also adopt other transmission methods such as gear + gear, gear + rack, magnetic wheel rotation, synchronous wheel rotation, and friction rotation, which are not limited here.

[0043] Please refer to the following: Figures 6 to 8 In some embodiments, considering that the jig 10 is positioned at the spraying station 20 before spraying, in order to drive the transmission mechanism, the driving mechanism may include an active driving mechanism 21 located at the spraying station 20. The active driving mechanism 21 is used to cooperate with the transmission mechanism when the jig 10 is positioned at the spraying station 20 to drive the transmission mechanism. As can be seen from the above, the transmission mechanism includes a first gear 131 and a transmission component 132, and the active driving mechanism 21 cooperates with the first gear 131 to drive the first gear 131.

[0044] Furthermore, in order for the active drive mechanism 21 to drive the first gear 131, the active drive mechanism 21 may include a first drive motor 211 and a third gear 212. The third gear 212 is connected to the first drive motor 211. When the fixture 10 is positioned at the spraying station 20, the third gear 212 is used to mesh with the first gear 131 to drive the first gear 131 to rotate under the drive of the first drive motor 211, thereby driving the multiple positioning components 12 to rotate.

[0045] It is understood that the driving mechanism 21 can drive the transmission mechanism in addition to the gear + gear transmission method exemplified in this embodiment. Other transmission methods such as gear + rack, magnetic wheel rotation, synchronous wheel rotation, and friction rotation can also be used, and these are not limited here.

[0046] In some embodiments, the third gear 212 may include multiple sub-gears 2121, which are sequentially meshed along a direction away from the fixture 10 and towards the fixture 10. The sub-gears 2121 away from the fixture 10 are connected to the first drive motor 211, while the sub-gears 2121 closer to the fixture 10 are used for meshing with the first gear 131. This design, by positioning the first drive motor 211 away from the fixture 10, creates more clearance space, preventing interference between the first drive motor 211 and the fixture 10. Furthermore, by using multiple sub-gears 2121, the problem of the first drive motor 211 being far from the fixture 10 can be solved, enabling the meshing connection between the third gear 212 and the first gear 131.

[0047] For example, there are three sub-gears 2121. It is understood that in other embodiments, there may be two, four or more sub-gears 2121, which is not limited here.

[0048] Furthermore, in order to install and fix the first drive motor 211 and multiple sub-gears 2121, the active drive mechanism 21 may also include a mounting plate 213. The mounting plate 213 is installed on the spraying station 20. The first drive motor 211 is located on the bottom of the mounting plate 213 away from the fixture 10, and the multiple sub-gears 2121 are located on the top of the mounting plate 213.

[0049] In some embodiments, the spraying station 20 may also be equipped with a second drive motor 22, which is connected to the active drive mechanism 21 to drive the active drive mechanism 21 to move in a direction close to the fixture 10 or in a direction away from the fixture 10. With this design, when the fixture 10 moves to the spraying station 20, the second drive mechanism drives the active drive mechanism 21 to move in a direction away from the fixture 10, thereby avoiding the fixture 10 and allowing the fixture 10 to slide more smoothly; when the fixture 10 is in place, the second drive mechanism drives the active drive mechanism 21 to move in a direction close to the fixture 10, so that the third gear 212 can mesh with the first gear 131.

[0050] Please see Figure 9 and Figure 10 In some embodiments, the driving mechanism may further include a first driving mechanism 31 and a passive driving mechanism 32 disposed at the curing station 30. The first driving mechanism 31 is used to drive the fixture 10 to move relative to the curing station 30, and the passive driving mechanism 32 is used to cooperate with the transmission mechanism when the fixture 10 moves to drive the transmission mechanism. As can be seen from the above, the transmission mechanism includes a first gear 131 and a transmission component 132, and the passive driving mechanism 32 cooperates with the first gear 131 to drive the first gear 131.

[0051] Furthermore, the passive drive mechanism 32 is a rack, with the rack extending in the same direction as the conveyor track 50. The first gear 131 meshes with the rack. When the fixture 10 moves relative to the curing station 30, the first gear 131 drives multiple positioning components 12 to rotate under the action of the rack. With this design, combined with the movement of the fixture 10 relative to the curing station 30, the meshing of the rack and the first gear 131 is sufficient to drive the first gear 131 to rotate, eliminating the need for an additional drive mechanism and simplifying the structure of the entire production equipment.

[0052] It is understood that the driving mechanism 32 can drive the transmission mechanism in addition to the gear + rack transmission method shown in this embodiment. Other transmission methods such as gear + gear, magnetic wheel rotation, synchronous wheel rotation and friction rotation can also be used, and are not limited here.

[0053] The production equipment provided in this application includes a main body, a conveyor track 50, and a fixture 10. The conveyor track 50 is provided with spraying stations 20 and curing stations 30 at intervals. The fixture 10 is movably disposed on the conveyor track 50. The fixture 10 can be conveyed from the spraying station 20 to the curing station 30 by means of a prying motion. The fixture 10 includes a base 11, a plurality of positioning components 12, and a transmission mechanism. The plurality of positioning components 12 are rotatably disposed on the base 11 and are used to position workpieces 40 one by one. The transmission mechanism is disposed on the base 11 and is connected to the plurality of positioning components 12. The transmission mechanism is used to cooperate with the drive mechanism of the production equipment to drive the plurality of positioning components 12 to rotate, thereby driving the plurality of workpieces 40 to rotate. This production equipment is a spray coating production equipment. The jig 10 is positioned at the spray coating station 20 for spray coating, and then moves and cures simultaneously at the curing station 30. The jig 10 is used to hold the workpiece 40, which is a battery cell. The jig 10 rotates between the spray coating station 20 and the curing station 30 of the spray coating production equipment, allowing the battery cell to complete the spray coating process on the production line. This design, through the cooperation of a transmission mechanism and a drive mechanism, allows the battery cell to rotate during the spray coating process, thereby improving the spray coating efficiency and quality.
