In order to improve the spraying efficiency, the bearing module has multiple bearing modules. Each bearing module can comprise a base and a bearing assembly rotatably arranged on the base. A worker can place a workpiece on the bearing assembly, and then move the base to the vicinity of the driving module and the spraying module. The driving module is then engaged with the bearing assembly on the bearing module, and then the driving module drives the bearing assembly to rotate, thereby changing the angle of the workpiece relative to the spraying end of the spraying module, and the workpiece can be sprayed on the periphery.

[0032] As Figure 1 As shown in FIG. 5, an auxiliary positioning direction-changing machine according to the first embodiment of the present application comprises a bearing station module 100 and a driving module 200, the bearing station module 100 comprises a base 110, a bearing assembly 120 rotatably arranged on the base 110, and a positioning assembly 130 movably arranged on the base 110, the bearing assembly 120 is used for placing a workpiece, and the positioning assembly 130 can be engaged with the bearing assembly 120 to limit the rotation of the bearing assembly 120, the driving module 200 comprises a base frame 210, a first driving assembly 220 movably arranged on the base frame 210, and an unlocking assembly 230 arranged on the base frame 210 or the first driving assembly 220, the first driving assembly 220 can be close to the bearing assembly 120 to engage or away from the bearing assembly 120 to disengage, the unlocking assembly 230 can act on the positioning assembly 130 to make the positioning assembly 130 disengage from the bearing assembly 120, and when the positioning assembly 130 disengages from the bearing assembly 120 and the first driving assembly 220 engages with the bearing assembly 120, the first driving assembly 220 can drive the bearing assembly 120 to rotate.

[0033] It should be noted that the bearing station module 100 can be multiple, and in order to save costs, the driving module 200 is generally only arranged one to cooperate with the corresponding spraying module 600, and the user can place the workpieces one by one on the multiple bearing station modules 100, move the workpieces which have not been sprayed to the driving module 200 through the bearing station module 100 to engage, and spray by the spraying module 600, and the sprayed workpieces can be removed from the driving module 200 by disassembling the bearing station module 100 bearing the workpieces, and this process greatly improves the spraying efficiency.

[0034] In the spraying process, the user can first place the workpiece on the bearing assembly 120, the positioning assembly 130 is engaged with the bearing assembly 120 to limit the rotation of the bearing assembly 120, to prevent the deflection of the bearing assembly 120 and the workpiece during the movement of the base 110, when the workpiece needs to be sprayed, the user moves the base 110 to the vicinity of the driving module 200, the first driving assembly 220 is close to and combined with the bearing assembly 120, in addition, the unlocking assembly 230 can also act on the positioning assembly 130, so that the positioning assembly 130 is separated from the bearing assembly 120, thereby releasing the rotation limitation of the positioning assembly 130 on the bearing assembly 120, the first driving assembly 220 can drive the bearing assembly 120 and the workpiece to rotate, and cooperate with the spraying module 600 to complete the spraying process, the design can limit the orientation of the bearing assembly 120, and is simple and convenient to use.

[0035] In some embodiments of the application, as shown in Figure 3 、 4 , the first driving assembly 220 includes a movable seat 221 movably arranged on the base frame 210 and a first driving part 222 arranged on the movable seat 221, and the unlocking assembly 230 is arranged on the movable seat 221.

Figure 1 , 2 The bearing station module 100 further comprises a track module 400, the bearing station module 100 is multiple and movably arranged on the track module 400, the driving module 200 is located on one side of the extension direction of the track module 400, there are multiple bearing station modules 100 on the track module 400, the user can set the driving module 200 at a certain position of the track module 400, when the bearing station module 100 moves to the position to combine with the driving module 200, the workpiece on the bearing station module 100 can be sprayed by the spraying module 600, and the workpiece on the bearing station module 100 in front of the driving module 200 in the moving direction is generally the workpiece that has been sprayed, and the user can take out the workpiece thereon, and the user can place the workpiece on the bearing station module 100 behind the driving module 200 in the moving direction, so as to facilitate subsequent spraying, thereby the spraying efficiency can be greatly improved.

[0046] In some embodiments of the present application, as shown in FIGS. Figure 1 , 2 The track module 400 is provided with a second driving assembly 410, the second driving assembly 410 is connected with each bearing station module 100 respectively to drive the bearing station module 100 to move along the track module 400, so that the spraying process is orderly carried out.

[0047] Specifically, the track module 400 can be a straight track, a curved track, or a ring track, etc. In the embodiment of the ring track, the second driving assembly 410 can include a motor and a belt. The motor can drive the belt arranged along the extension direction of the track module 400 to run through the components such as the driving wheel and the driven wheel. The base 110 of each carrying station module 100 can be connected with the belt, so as to drive each carrying station module 100 to move along the track module 400.

[0048] Specifically, the base 110 can be slidably arranged relative to the track module 400, or a roller can be arranged on the base 110. The roller rolls on the track module 400, so that the carrying station module 100 moves on the track module 400. As shown in Figure 4 、 5 Each roller on the carrying station module 100 can be provided with four rollers, which is not limited in particular.

[0049] In some embodiments of the present application, as shown in Figure 3 The track module 400 includes the first guide rail 420 and the second guide rail 430 arranged side by side. The first guide rail 420 and the second guide rail 430 have a gap 440 therebetween. The base 110 is movably arranged on the first guide rail 420 and the second guide rail 430. The base 110 is provided with an auxiliary guide assembly 500. The auxiliary guide assembly 500 is located in the gap 440 and can movably abut against the wall surface on both sides of the gap 440.

[0050] The auxiliary guide assembly 500 can movably abut against the wall surface on both sides of the gap 440, so as to prevent the carrying station module 100 from being separated from the track module 400.

[0051] In some embodiments of the present application, as shown in Figure 5 The auxiliary guide assembly 500 includes at least one set of guide units 510. Specifically, as shown in Figure 5 The guide unit 510 can have two sets, but is not limited in particular. The guide unit 510 includes the first guide piece 511 and the second guide piece 512. The base 110 is provided with an elastic assembly 513. One of the first guide piece 511 and the second guide piece 512 is arranged on the elastic assembly 513, and the other is arranged on the base 110. The first guide piece 511 can movably abut against the wall surface on one side of the gap 440, and the second guide piece 512 can movably abut against the wall surface on the other side of the gap 440.

[0052] The first guide member 511 and the second guide member 512 can be arranged on the elastic assembly 513, and the first guide member 511 is arranged on the elastic assembly 513 as an example.

[0053] Since the gap 440 between the first guide rail 420 and the second guide rail 430 has a width that changes due to manufacturing errors or is located at a bending position, if the distance between the first guide member 511 and the second guide member 512 is unchanged, the force applied by the first guide member 511 to the side wall of the gap 440 will increase, which will hinder the movement of the carrying station module 100 and make the movement not smooth.

[0054] The first guide member 511 and the second guide member 512 are arranged, the first guide member 511 can be in movable abutment with the wall surface on one side of the gap 440, and the second guide member 512 can be in movable abutment with the wall surface on the other side of the gap 440, thereby preventing the carrying station module 100 from being separated from the track module 400, and when the gap 440 between the first guide rail 420 and the second guide rail 430 changes, the wall surface on one side of the gap 440 acts on the first guide member 511, which can cause the elastic assembly 513 to deform, thereby slightly shortening the distance between the first guide member 511 and the second guide member 512, to adapt to the width of the gap 440 between the first guide rail 420 and the second guide rail 430, and make the movement of the carrying station module 100 more smooth.

[0056] The first guide member 511 and the second guide member 512 can be formed by a sliding block or a pulley, and the side walls on both sides of the gap 440 can be formed by the wall surfaces of the first guide rail 420 and the second guide rail 430, respectively.

[0057] In some embodiments of the present application, as shown in Figure 5As shown, the first guide 511 is closer to the driving module 200 relative to the second guide 512, when the first driving assembly 220 is close to the bearing assembly 120 and engages, the driving module 200 will exert a force on the bearing assembly 120, if the first guide 511 is located on the side far from the driving module 200, the force will cause the elastic assembly 513 to deform, causing the base 110 to deviate from the position of the bearing assembly 120, and the first driving assembly 220 is not easy to access the bearing assembly 120, therefore, the first guide 511 is arranged on the side closer to the driving module 200 relative to the second guide 512.

[0058] Specifically, as shown in the drawings, Figure 5 The first guide rail 420 is close to the driving module 200, so that the first guide 511 is in movable abutment with the wall surface of the first guide rail 420, and the second guide 512 is in movable abutment with the wall surface of the second guide rail 430.

[0060] The spraying module 600 can be selected from conventional spraying equipment, and generally comprises a barrel, a spray gun, a displacement driving mechanism, etc., and can spray the workpiece.

[0061] The spraying device of the present application can cooperate with the auxiliary positioning and direction changing machine, so that the bearing assembly 120 will not be deflected before being accessed by the first driving assembly 220, so that the workpiece can be connected with the spraying end of the spraying module 600, and the spraying effect is improved.
