[0069] In the embodiment, as shown in Figures 2 to 4 The turnover mechanism 100 further comprises a turnover driving device 141, a first pulley 142 connected with a driving end of the turnover driving device 141, a second pulley 143 connected with the second turnover disc 120, and a third pulley 144 connected with the first turnover disc 110. The first pulley 142 and the second pulley 143 are provided with a first synchronous belt 145. The second pulley 143 and the third pulley 144 are provided with a second synchronous belt 146. In the embodiment, the turnover driving device 141 drives the first turnover disc 110 and the second turnover disc 120 to rotate simultaneously through the design of the belt transmission, which effectively ensures the synchronization and alignment accuracy of the first turnover disc 110 and the second turnover disc 120 and ensures the safe operation of the turnover mechanism 100.

[0070] Preferably, the turnover driving device 141 is a servo motor, which can effectively ensure the rotation accuracy and stable operation of the first turnover disc 110 and the second turnover disc 120.

[0080] Further, the second pulley 143 is sleeved on the second shaft portion 171 and is connected through a second flat key 173 to avoid the rotation of the second pulley 143 on the second shaft portion 171. The second pulley 143 is radially threadedly connected with a fourth fastener 174 which abuts against the second flat key 173 on the first shaft portion 151 to prevent the displacement of the second pulley 143 on the first shaft portion 151.

[0081] Further, the second rotating member 170 further comprises a second connecting portion 175 which is fixedly connected with the second turnover disc 120 through a screwing member.

In this embodiment, when the product 500 on the conveying belt 210 corresponds to the feeding position, under the guiding action of the first guiding assembly 330, the first pushing mechanism 300 drives the first pushing member 310 to move to transfer the product 500 on the conveying belt 210 to the first carrying space at the feeding position on the first turnover disc 110.

[0102] Preferably, the first pushing driving device 320 is a push rod cylinder. Specifically, the conveying mechanism 200 is provided with a support seat 360, which is located on the opposite side of the turnover mechanism 100.

The feeding process is accurate and stable, the structure is simple, and the service life is long.

[0107] It is worth mentioning that when the products 500 do not need to be flipped and transferred to the next station, the blocking driving device 350 drives the blocking rod 340 to move away above the conveying belt 210, so that the products 500 can be directly transferred to the next station on the conveying belt 210.

[0114] Embodiment two

[0115] The turning method of the turning device in embodiment one can be used, and referring to Figure 11 , the turning method comprises the following steps:

[0116] S100, the first turning disc 110 rotates around the first direction to turn the product 500 by 90°;

[0117] S200, the transfer assembly 130 transfers the product 500 turned by 90° from the first turning disc 110 to the second turning disc 120;

[0118] S300, the second turning disc 120 rotates around the first direction to turn the product 500 turned by 90° again by 90°.

[0119] Figure 12 is a detailed step flow chart of the turning method provided by the embodiment, and the turning method will be described in detail according to Figure 12 .

[0120] Step one, the conveying mechanism 200 conveys the product 500.

[0121] Specifically, the conveying driving device drives the conveyor belt 210 to rotate circularly to convey the product 500 to the upper feeding position.

[0122] Step two, the first pushing mechanism 300 transfers the product 500 corresponding to the upper feeding position to the first turning disc 110.

[0123] Before the product 500 is transferred to the position corresponding to the loading position on the conveying belt 210, the incoming product sensor 220 detects the incoming product 500, and after detecting the incoming product 500, the stop driving device 350 drives the stop lever 340 to move so that the stop lever 340 is transversely arranged on the conveying mechanism 200 to stop the incoming product 500.

[0124] Further, after the product 500 is stopped by the stop lever 340, under the guidance of the first guide assembly 330, the first pushing mechanism 300 drives the first pushing member 310 to move so as to transfer the product 500 on the conveying belt 210 to the first carrying space on the first turnover disc 110 at the loading position.

[0125] Step three, the turnover mechanism 100 turns over the product 500.

[0126] Specifically, step three includes the following steps:

[0127] S310, the turnover driving device 141 drives the first turnover disc 110 and the second turnover disc 120 to simultaneously rotate by 90° through belt transmission so as to turn over the product 500 by 90°.

[0128] S320, the third driving device 134 drives the transition plate 135 to move along the vertical direction to the splicing position.

[0129] Specifically, when the transition plate 135 is located at the splicing position, the transition plate 135 is spliced with the first carrying plate 111 and the second carrying plate 121 in the horizontal state to form an integrated body, and fills the gap between the first carrying plate 111 and the second carrying plate 121.

[0130] S330, the transfer assembly 130 transfers the product 500 turned over by 90° from the first turnover disc 110 to the second turnover disc 120.

[0131] Specifically, first, the second driving device 132 drives the yoke 133 to move along the first direction to the pushing position so as to insert the yoke 133 into the accommodation slot 112 of the first carrying plate 111; then, the first driving device 131 drives the second driving device 132 and the yoke 133 to move along the second direction so as to push the innermost sub-product 510 with the yoke 133, and the product 500 moves along the second direction so that the outermost sub-product 510 abuts against the second carrying plate 121 in the vertical state; finally, the first driving device 131, the second driving device 132 and the third driving device 134 return to the initial position to wait for the next round of product 500 to be transferred.

[0132] S340, the turnover driving device 141 drives the first turnover disc 110 and the second turnover disc 120 to simultaneously rotate by 90° again through belt transmission, so as to turn over the product 500 by 90° again.

[0133] It is worth mentioning that a step S311 can be inserted between the step S310 and the step S320, specifically:

[0134] S311, whether the position sensor 157 has a signal, if the signal is generated, proceed to step S320; if there is no signal, the turnover device is automatically stopped and an alarm is given.

[0135] In the embodiment, the signal generated by the position sensor 157 proves that the first turnover disc 110 and the second turnover disc 120 are accurately rotated by 90°, and if the position sensor 157 has no signal, it indicates that the first turnover disc 110 and the second turnover disc 120 are not rotated to 90° or are rotated more than 90°, thereby ensuring the safe transfer of the product 500 between the first turnover disc 110 and the second turnover disc 120, and avoiding the collision between the transition plate 135 and the first turnover disc 110 and the second turnover disc 120.

[0136] Further, if the position sensor 157 is designed to generate an induction signal when the induction disc 156 is rotated by 90° with the first shaft part 151, a step S341 can be added after the step S340, specifically:

[0137] S341, whether the position sensor 157 has a signal, if the signal is generated, proceed to step S320; if there is no signal, the turnover device is automatically stopped and an alarm is given.

[0138] The function of the step S341 is similar to that of the step S311, which can ensure the safe transfer of the product 500 between the second turnover disc 120 and the conveying belt 210.

[0139] Step four, the second pushing mechanism 400 pushes the product 500 with the completed surface out of the second turnover disc 120.

[0140] Specifically, under the guidance of the second guide assembly 430, the second pushing mechanism 400 drives the second pushing piece 420 to move to transfer the product 500 with the completed surface to the conveying belt 210, and the conveying belt 210 transfers the product 500 with the completed surface to the next station.
