Description

Technical Field

[0001] This utility model relates to the field of automated equipment, specifically to a flipping device. Background Technology

[0002] Conveyor line production is a common production method in modern industrial manufacturing. According to the process flow of the 86-type switch production line, many workstations on the production line still require manual operation. Since some workstations require the products to be flipped and installed, the manual flipping method is labor-intensive, inefficient, and costly for a large number of products, and cannot meet the usage requirements. Utility Model Content

[0003] The purpose of this invention is to overcome at least one defect of the prior art and provide a flipping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flipping device includes a transmission mechanism and a flipping mechanism. The transmission mechanism is used to convey products. The flipping mechanism includes a rotatable turntable mechanism. At least one receiving groove is provided on the radial sidewall of the turntable mechanism. The turntable mechanism is located on the conveying path of the transmission belt of the transmission mechanism, dividing the transmission belt into a first part and a second part, which are located on both radial sides of the turntable mechanism. When the turntable mechanism rotates to the position where the receiving groove is opposite to the first part of the transmission belt, the first part of the transmission belt conveys the product into the receiving groove. When the turntable mechanism rotates to the position where the receiving groove is opposite to the second part of the transmission belt, the second part of the transmission belt conveys the product away from the turntable mechanism.

[0006] The flipping mechanism includes a turntable mechanism and an active mechanism.

[0007] The active mechanism includes a first driving member and a first active member. The first active member includes a first limiting part and a first driving part. The turntable mechanism includes a first driven member that is rotatably disposed. The radial sidewall of the first driven member is provided with a plurality of sliding grooves. A second limiting part is provided between adjacent sliding grooves. The sliding grooves are elongated and extend toward the rotation center of the first driven member. The second limiting part includes an arc-shaped groove structure. The first limiting part is a first arc-shaped structure corresponding to the second limiting part. The center of the arc-shaped groove structure and the center of the first arc-shaped structure coincide.

[0008] The first driving member drives the first active member to rotate, causing the first driving part and the first limiting part to alternately cooperate with the slide groove and the second limiting part of the first driven member. When the first driving part cooperates with the slide groove, the first driving part rotates into and out of the slide groove as the first active member rotates and pushes the first driven member to rotate through the slide groove. When the first limiting part cooperates with the second limiting part, the first arc-shaped structure and the arc-shaped groove structure rotate and cooperate, limiting the first driven member to stop rotating.

[0009] Furthermore, the first driving part is a sliding shaft disposed on the first driving member.

[0010] Furthermore, the first arc-shaped structure of the first active member is provided with an outwardly protruding first rib, and the side wall of the arc-shaped groove structure is provided with a first sliding groove. When the first arc-shaped structure and the arc-shaped groove structure are rotated together, the first rib extends into the first sliding groove.

[0011] Furthermore, the turntable mechanism also includes a second follower, which is connected to the first follower and rotates synchronously. The second follower has a plurality of clamping grooves on its radial side as receiving grooves.

[0012] Furthermore, the first follower and the second follower are stacked along the axis of rotation. The multiple sliding grooves on the first follower correspond one-to-one with the multiple clamping grooves on the second follower. The clamping grooves and the sliding grooves together form the receiving groove.

[0013] Furthermore, the groove on the first follower also serves as the receiving groove.

[0014] Furthermore, there is a gap between the first follower and the second follower, and the first follower and the second follower are axially movable relative to each other to adjust the size of the gap.

[0015] Furthermore, the first driven member is provided with eight sliding grooves evenly, and correspondingly with eight second limiting parts, and the turntable mechanism is provided with eight receiving grooves.

[0016] Furthermore, it also includes a fixing mechanism, which comprises at least two fixing beams spaced apart, with the transmission belt located between the two fixing beams.

[0017] Furthermore, at least two guide members are provided opposite to each other on the loading side of the two fixed beams of the fixing mechanism. The two guide members are located above the transmission belt, and there is a channel for the product to pass through between the lower side of the two guide members and the transmission belt.

[0018] Furthermore, the distance between the two guide members is less than the width of the product, and the height of the channel is adapted to the thickness of the product.

[0019] Furthermore, a first adjustment mechanism for adjusting the height of the channel is provided between the guide member and the fixed beam, and / or a second adjustment structure for adjusting the distance between the two guide members.

[0020] Furthermore, the turntable mechanism also includes a mounting base and a second driven member. Two mounting bases are arranged opposite each other on the inner sides of the two fixed beams. A rotating shaft assembly is connected to the mounting base. The rotating shaft of the rotating shaft assembly is connected to the first driven member and the second driven member. The first driven member and the second driven member rotate synchronously through the rotating shaft assembly.

[0021] Furthermore, the rotating shaft assembly includes a bearing housing, a bearing, a rotating shaft, and a bearing cover plate. The bearing housing is connected to the mounting base. The rotating shaft is disposed inside the bearing. The rotating shaft is connected to the first driven member and the second driven member. The bearing cover plate is fixed to both ends of the bearing housing by fasteners to seal the bearing.

[0022] Furthermore, the first active member is also provided with a first notch, which is opposite to the first arc-shaped structure and is located on both radial sides of the first active member. The first notch allows the second limiting part to pass through when rotating.

[0023] Furthermore, the first active member is columnar, with one end connected to the first driving member and the other end extending to the other side of the first driven member and having a cam plate protruding radially. The cam plate and the first driving member are located on opposite sides of the first driven member. The cam plate has a sliding shaft protruding towards the first driven member as the first driving part. The first active member has the first arc-shaped structure and the first notch on its radial sides corresponding to the first driven member. The direction of the cam plate protrusion corresponds to the first notch, and both are located on the same radial side of the first active member.

[0024] Furthermore, the transmission mechanism includes two parallel transmission belts, with the turntable mechanism disposed between the two transmission belts.

[0025] Furthermore, it also includes a controller and a photoelectric mechanism, wherein the controller is connected to the active mechanism, the photoelectric mechanism and the transmission mechanism.

[0026] Furthermore, the photoelectric mechanism includes a first sensing element for sensing the position of the product on the transmission belt.

[0027] Furthermore, the photoelectric mechanism includes a second sensor and a third sensor. The second sensor is disposed on the feeding side of the turntable mechanism and is used to sense whether the product is clamped by the turntable mechanism. The third sensor is disposed on the unloading side of the turntable mechanism and is used to sense whether the product leaves the turntable mechanism.

[0028] Furthermore, the photoelectric mechanism includes a fourth sensor; the fourth sensor is disposed on the active mechanism and is used to sense the position of the first driving part of the first active component.

[0029] The flipping device of this utility model adopts a driving cooperation structure of the first driving part of the first active member and the sliding groove of the first driven member, and a limiting cooperation structure of the first arc-shaped structure and the arc-shaped groove structure rotating together. The first driven member can rotate and remain locked alternately, so as to simply and reliably control the start and stop position of the first driven member, thereby conveying the product into or out of the receiving groove of the turntable mechanism, so that the product can be automatically flipped in both directions without manual flipping, improving work efficiency and reducing energy consumption.

[0030] Furthermore, the flipping device of this application adopts a cooperative structure of the first protruding rib and the first sliding groove, so that the first driving member will not come out during the rotation in the arc-shaped groove structure, the rotation is smooth, and the first driven member is locked at the same time.

[0031] In addition, the first driven member is used to cooperate with the first driving part of the first driving member to realize transmission and drive the turntable mechanism to rotate. It can also be used to clamp the product in the receiving groove, which achieves multiple benefits and simplifies the structure.

[0032] Furthermore, the flipping device of this application adopts a structure in which the distance between the first follower and the second follower can be adjusted, thereby adapting to products of various sizes and positioning the products so that they will not fall off during rotation.

[0033] In addition, the flipping device is equipped with guide members. The distance between the two guide members is less than the width of the product. There is a channel for the product to pass through between the lower side of the two guide members and the transmission belt. The height of the channel is adapted to the thickness of the product. In this way, a product can pass under the two guide members and reliably enter the receiving slot of the turntable mechanism. At the same time, the guide members can block the products stacked on the transmission belt and make the stacked products fall off. Attached Figure Description

[0053] Product 5. Detailed Implementation

[0054] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0055] The flipping device provided in this embodiment can be connected to the production line of product 5 to automatically flip product 5 from side to side and automatically load and unload product 5. Product 5 in this embodiment is a mounting bracket for an 86-type switch socket. Of course, the flipping device in this embodiment can also be used to flip other products with similar mounting brackets.

[0056] like Figure 1 , 2 As shown in Figure 3, the flipping device includes a transmission mechanism 1 and a flipping mechanism 2. The transmission mechanism 1 is used to convey the product 5, and the flipping mechanism 2 is used to drive the product 5 to flip its front and back sides.

[0057] The transmission mechanism 1 is used to convey the product 5 to the flipping mechanism 2 and to convey the flipped product 5 away from the flipping mechanism 2. The transmission mechanism 1 includes a second drive member and a transmission belt. The second drive member is configured to drive the transmission belt, and the transmission belt is used to convey the product 5.

[0058] The flipping mechanism 2 includes a rotatable turntable mechanism 22. The turntable mechanism 22 has at least one receiving groove on its radial sidewall. The turntable mechanism 22 is located on the transmission path of the transmission belt of the transmission mechanism 1, dividing the transmission belt into a first part and a second part of the transmission belt arranged on both radial sides of the turntable mechanism 22. When the turntable mechanism 22 rotates to the point where the receiving groove is opposite to the first part of the transmission belt, the first part of the transmission belt conveys the product 5 into the receiving groove. When the turntable mechanism 22 rotates 180 degrees to the point where the receiving groove is opposite to the second part of the transmission belt, the second part of the transmission belt conveys the product 5 away from the turntable mechanism 22. In this way, the front and back sides of the product 5 are flipped through the turntable mechanism 22.

[0059] An improvement of this application is to provide a novel flipping mechanism 2, which includes a turntable mechanism 22 and an active mechanism 21. The active mechanism 21 includes a first driving member 212 and a first active member 211. The first active member 211 includes a first limiting part 2114 and a first driving part 2112. The turntable mechanism 22 includes a first driven member 221 that is rotatably disposed. The radial sidewall of the first driven member 221 is provided with a plurality of grooves 2212. A second limiting part 2214 is provided between adjacent grooves 2212. The grooves 2212 are elongated and extend toward the rotation center of the first driven member 221. The second limiting part 2214 includes an arc-shaped groove structure 2211. The first limiting part 2114 is a first arc-shaped structure 2111 corresponding to the second limiting part 2214. The centers of the arc-shaped groove structure 2211 and the first arc-shaped structure 2111 coincide.

[0060] The first driving member 212 drives the first active member 211 to rotate, causing the first driving part 2112 and the first limiting part 2114 to alternately cooperate with the slide groove 2212 and the second limiting part 2214 of the first driven member 221. When the first driving part 2112 cooperates with the slide groove 2212 of the first driven member 221, the first driving part 2112 rotates into and out of the slide groove 2212 as the first active member 211 rotates and pushes the first driven member 221 to rotate through the slide groove 2212. When the first limiting part 2114 cooperates with the second limiting part 2214 of the first driven member 221, the first arc-shaped structure 2111 rotates and cooperates with the arc-shaped groove structure 2211, limiting the first driven member 221 to stop rotating.

[0061] Specifically, such as Figure 4 , 7As shown, in this embodiment, the first driven member 221 is uniformly provided with eight sliding grooves 2212, and correspondingly provided with eight second limiting parts 2214. The turntable mechanism 22 is provided with eight receiving slots. The specific process of this embodiment is as follows: the first driving member 212 drives the first active member 211 to rotate. The first driving part 2112 of the first active member 211 contacts the edge of the sliding groove 2212 of the first driven member 221. As the first active member 211 rotates, the first driving part 2112 slides into the sliding groove 2212. The first driving part 2112 gradually extends into the sliding groove 2212, slides towards the rotation center of the first driven member 221, and pushes the first driven member 221 to rotate. After rotating a certain angle, the first driving part 2112 gradually rotates out of the sliding groove 2212, slides away from the rotation center of the first driven member 221, and pushes the first driven member 221 to continue rotating until the first driving part 2112 disengages from the sliding groove 2212. At this time, the first driven member 221 rotates 45°; after the first driving part 2112 disengages from the slide groove 2212, the first arc-shaped structure 2111 of the first driving member 211 rotates into the arc-shaped groove structure 2211 of the first driven member 221. The first arc-shaped structure 2111 rotates within the arc-shaped groove structure 2211 and restricts the first driven member 221, causing the first driven member 221 to stop rotating. During the process of the first driving member 211 rotating 180° again, the first driven member 221 remains locked (i.e., stationary). At the end point of the first driving member 211 rotating 180° again, the first arc-shaped structure 2111 rotates out of the arc-shaped groove structure 2211. The first driving part 2112 of the first driving member 211 contacts the edge of the slide groove 2212 of the first driven member 221 and is about to rotate into the slide groove 2212. After four cycles of rotation and locking, the first driven member rotates 180°, thus completing the front-to-back flipping of the product 5. It should be noted that the first driven member 221 is not limited to having eight slide grooves 2212 and eight second limiting parts 2214; fewer or more slide grooves 2212 and second limiting parts 2214 may be provided.

[0062] The flipping mechanism 2 in this embodiment adopts a driving engagement structure of the first driving part 2112 of the first active member 211 and the sliding groove 2212 of the first driven member 221, and a limiting engagement structure of the first arc-shaped structure 2111 and the arc-shaped groove structure 2211 rotating together. The first driven member can rotate and remain locked alternately, thereby enabling simple and reliable control of the start and stop position of the first driven member 221. This allows the product 5 to be conveyed into or out of the receiving groove of the turntable mechanism 22, so that the product 5 can be automatically flipped between the front and back sides without manual flipping, improving work efficiency and reducing energy consumption.

[0063] like Figures 2-5 The first active member 211 is a cam, flat in shape. A first limiting portion 2114 and a first driving portion 2112 are provided on both radial sides of the first active member 211. The first limiting portion 2114 includes a protruding first arc-shaped structure 2111. The first driving portion 2112 is a sliding shaft 214 on the first active member 211. The sliding shaft 214 rotates synchronously with the first active member 211 and is used to extend into the slide groove 2212. Further, the sliding shaft 214 is a cam bearing follower. Preferably, the cam bearing follower is provided with rollers to facilitate sliding and driving engagement with the slide groove 2212.

[0064] Furthermore, the first arc-shaped structure 2111 of the first active member 211 is provided with an outwardly protruding first rib, and the side wall of the arc-shaped groove structure 2211 is provided with a first sliding groove 2215. Figure 5 When the first arc-shaped structure 2111 and the arc-shaped groove structure 2211 are rotatably engaged, the first protruding rib extends into the first sliding groove 2215, ensuring that the first driving member 211 will not dislodge during rotation within the arc-shaped groove structure 2211, thus ensuring smooth rotation, and simultaneously locking the first driven member 221. Alternatively, the first protruding rib and the first sliding groove 2215 may not be provided.

[0065] like Figure 2 , 6 As shown, the turntable mechanism 22 also includes a second follower 222, which is connected to and rotates synchronously with the first follower 221. The second follower 222 has multiple clamping grooves 2221 on its radial side as receiving grooves. The multiple clamping grooves 2221 are evenly distributed on the radial side of the second follower 222, and each clamping groove 2221 extends in a long strip towards the rotation center of the second follower 222.

[0066] In a preferred embodiment, the first follower 221 and the second follower 222 are stacked along the axis of rotation. The multiple sliding grooves 2212 on the first follower 221 correspond one-to-one with the multiple clamping grooves 2221 on the second follower 222. The clamping grooves 2221 and the sliding grooves 2212 together form the receiving groove, which is used to clamp the product 5 and improve the reliability of clamping the product 5. The sliding grooves 2212 are used to cooperate with the first driving part 2112 of the first driving member 211 to realize transmission and drive the turntable mechanism 22 to rotate. They can also be used to clamp the product 5 in the receiving groove, which achieves multiple benefits and simplifies the structure.

[0067] As an alternative embodiment, the second driven member 222 can be omitted, and the sliding groove 2212 on the first driven member 221 can simultaneously serve as the receiving groove. The sliding groove 2212 is used to cooperate with the first driving part 2112 of the first driving member 211 to realize transmission, driving the turntable mechanism 22 to rotate, and can also be used to clamp the product 5 in the receiving groove, achieving multiple benefits and simplifying the structure. In addition, the first driven member 221 can also be provided with multiple clamping grooves that penetrate the first driven member 222 at intervals for clamping the product 5.

[0068] Specifically, both the first follower 221 and the second follower 222 are circular and flat. In this embodiment, the first follower 221 has eight grooves 2212 evenly distributed on its radial side. The grooves 2212 are elongated and extend towards the rotation center of the first follower 221. Eight second limiting parts 2214 are provided between the eight grooves 2212. The included angle between two adjacent grooves 2212 is 45°. The second follower 222 has eight clamping grooves 2221 corresponding to the eight grooves 2212. The eight grooves 2212 and the eight clamping grooves 2221 correspond one-to-one to form eight receiving grooves. The first driving member 211 rotates one revolution, causing the turntable mechanism 22 to rotate 45°. Thus, the turntable mechanism 22 can simultaneously hold four products 5. When the first arc-shaped structure 2111 and the arc-shaped groove structure 2211 rotate to limit the rotation of the first driven member 221, the transmission belt conveys the products 5 into or out of the receiving groove of the turntable mechanism 22. Of course, in other embodiments, the first driven member 221 and the second driven member 222 can also be rectangular or other polygonal.

[0069] Preferably, there is a gap between the first follower 221 and the second follower 222, and the first follower 221 and the second follower 222 are axially movable relative to each other to adjust the size of the gap. This embodiment adopts a structure in which the first follower 221 and the second follower 222 have an adjustable gap, thereby accommodating products 5 of various sizes, positioning the product 5, and preventing it from falling off during rotation.

[0070] Furthermore, a locking block can be provided between the first driven member 221 and the second driven member 222 to adjust the gap between them. Alternatively, the second driven member 222 can also be equipped with an adjusting nut, which, by adjusting the position of the adjusting nut on the shaft 2233 of the bearing 2232, can further adjust the gap between the first driven member 221 and the second driven member 222.

[0071] Preferred, such as Figure 6As shown, the first driven member 221 includes a first driven assembly 2216 and a second driven assembly 2217 stacked correspondingly. The first driven assembly 2216 and the second driven assembly 2217 are detachably connected and assembled to form the first driven member 221. The first driven assembly 2216 is disposed close to the second driven member 222, and the first driven assembly 2216 is provided with the first sliding groove 2215. Of course, the first sliding groove 2215 can also be disposed between the first driven assembly 2216 and the second driven assembly 2217 or on the second driven assembly 2217. Of course, the first driven assembly 2216 and the second driven assembly 2217 can also be integrally formed to form the first driven member 221. Further, the first driven assembly 2216 and the second driven assembly 2217 are respectively provided with connecting holes 2218, and the first driven assembly 2216 and the second driven assembly 2217 are connected by fasteners.

[0072] Furthermore, a buffer pad is provided at one end of the slide groove 2212 and the clamping groove 2221 near the bearing 2232 to prevent the product 5 from colliding with the slide groove 2212 and the clamping groove 2221.

[0073] Furthermore, the slide groove 2212 is chamfered to facilitate the rotation of the sliding shaft 214 into the slide groove 2212.

[0074] In another optional embodiment of the slide groove 2212, when the slide groove 2212 is not used to clamp the product 5, the slide groove 2212 may not penetrate through the first follower 221. The slide groove 2212 is a strip-shaped groove provided on the side wall of the first follower 221. The strip-shaped groove may be a recessed groove in the side wall of the first follower 221, or it may be an outwardly protruding annular groove protruding from the first follower 221.

[0075] Preferably, the clamping groove 2221 is chamfered to facilitate the insertion of the product 5 into the clamping groove 2221.

[0076] Preferred, such as Figure 1 As shown, the flipping device also includes a fixing mechanism 4, a photoelectric mechanism 3, a controller, and a flipping mechanism 2. The transmission mechanism 1, flipping mechanism 2, and photoelectric mechanism 3 are mounted on the fixing mechanism 4. The transmission mechanism 1, flipping mechanism 2, and photoelectric mechanism 3 are connected to the controller. The controller controls the movement of the transmission mechanism 1 and flipping mechanism 2. The photoelectric mechanism 3 monitors the position of the product 5 and / or whether the movement of the transmission mechanism 1 and flipping mechanism 2 is complete. The photoelectric mechanism 3 includes a photoelectric sensor and / or a proximity switch and / or a micro switch, etc. Alternatively, the controller and transmission mechanism 1 may not be mounted on the fixing mechanism 4.

[0077] The fixing mechanism 4 in this embodiment includes at least two fixing beams 41, which are spaced apart. The transmission belt is located between the two fixing beams 41, and the distance between the two fixing beams 41 is equivalent to the width of the product 5, which can guide the product 5 into the receiving groove of the turntable mechanism 22.

[0078] Preferably, at least two guide members 42 are arranged opposite each other on the loading side of the two fixed beams 41 of the fixing mechanism 4. The two guide members 42 are located above the transmission belt, and the distance between the two guide members 42 is less than the width of the product 5. There is a channel for the product 5 to pass through between the lower side of the two guide members 42 and the transmission belt. The height of the channel is adapted to the thickness of the product 5, so that a product 5 can pass under the two guide members 42 and reliably enter the receiving slot of the turntable mechanism 22. At the same time, the guide members 42 can block the products 5 stacked on the transmission belt, allowing the stacked products 5 to fall off. Preferably, the end of the guide member 42 away from the turntable mechanism 22 is provided with a chamfer to facilitate the product 5 to enter under the guide member 42. In this embodiment, the guide member 42 is U-shaped and clamped on the fixed beam 41 for easy adjustment and replacement. A first adjustment mechanism for adjusting the height of the channel and / or a second adjustment structure for adjusting the distance between the two guide members 42 are provided between the guide member 42 and the fixed beam 41. In this embodiment, the first adjustment mechanism is an elongated mounting hole provided on the guide member 42.

[0079] Preferred, such as Figure 1 As shown, the transmission mechanism 1 includes two parallel transmission belts, with the turntable mechanism 22 positioned between the two transmission belts. The transmission mechanism 1 is arranged in a straight line, and the second driving member drives the transmission belts to horizontally convey the product 5. The transmission mechanism 1 can also be a ring-shaped transmission mechanism, configured as a circular, elliptical, or quadrilateral transmission mechanism. Of course, the transmission mechanism 1 can also have more than two transmission belts.

[0080] Furthermore, a product fixing component is provided on the transmission belt to support the product 5 and prevent the product 5 from sliding. The product fixing component can be a corresponding limiting rib, on which the product 5 is placed and the limiting rib limits the position of the product 5.

[0081] In another optional embodiment of the transmission mechanism 1, the transmission mechanism 1 includes a first transmission structure and a second transmission structure arranged at intervals. The first transmission structure and the second transmission structure are respectively located on the loading side and unloading side of the turntable mechanism 22. The first transmission structure is used to convey the product 5 to the turntable mechanism 22, and the second transmission structure is used to convey the flipped product 5 away from the turntable mechanism 22.

[0082] In another optional embodiment of the transmission mechanism 1, a loading robot and an unloading robot are provided on the fixing mechanism 4. The loading robot is located on the loading side of the transmission mechanism 1 and is used to pick up the product 5 from the production line or the feeding table and place it onto the transmission mechanism 1. The unloading robot is located on the unloading side of the transmission mechanism 1 and is used to pick up the flipped product 5 from the transmission mechanism 1 and place it on a product 5 placement table or another switch assembly production line. The loading robot and the unloading robot can automatically place the product 5 on the transmission mechanism 1 and simultaneously pick up the flipped product 5 from the transmission mechanism 1, thereby improving production efficiency. It should be noted that the loading robot and the unloading robot are both existing technologies in the art and will not be described in detail here.

[0083] In a less desirable embodiment of the transmission mechanism 1, the product 5 is placed directly on the transmission mechanism 1 by a person or the flipped product 5 is picked up and removed from the transmission mechanism 1.

[0084] Preferred, such as Figure 2 , 3 As shown in Figure 5, the active mechanism 21 further includes a drive mounting plate 213, which is fixedly connected to the fixed beam 41 of the fixed mechanism 4. The first drive member 212 is fixedly connected to the drive mounting plate 213. The first active member 211 is mounted on the drive shaft at one end of the first drive member 212, and the first drive member 212 drives the first active member 211 to rotate.

[0085] Preferred, such as Figure 2 , 6 As shown, the turntable mechanism 22 further includes a mounting base 224 and a rotating shaft assembly 223. Two mounting bases 224 are arranged opposite each other on the inner sides of the two fixed beams 41. The rotating shaft assembly 223 is connected to the mounting base 224. The rotating shaft 2233 of the rotating shaft assembly 223 is connected to the first driven member 221 and the second driven member 222. The first driven member 221 and the second driven member 222 rotate synchronously through the rotating shaft assembly 223. The rotating shaft assembly 223 includes a bearing seat 2231, a bearing 2232, a rotating shaft 2233, and a bearing cover plate 2234. The bearing seat 2231 is connected to the mounting base 224. The rotating shaft 2233 is disposed inside the bearing 2232. The rotating shaft 2233 is connected to the first driven member 221 and the second driven member 222. The bearing cover plate 2234 is fixed to both ends of the bearing seat 2231 by fasteners to seal the bearing 2232.

[0086] Furthermore, the bearing 2232 is a deep groove ball bearing 2232. Specifically, the bearing 2232 includes an inner ring, an outer ring, rolling elements, and a cage. The inner ring is connected to the rotating shaft 2233 and rotates synchronously. The outer ring is fixedly connected to the bearing housing 2231. The opposite sides of the inner and outer rings are provided with multiple corresponding annular rolling grooves. The rolling elements (usually steel balls) roll within the rolling grooves, and the cage is used to space the rolling elements. Of course, other bearing structures can also be used.

[0087] Preferred, such as Figure 4 , 5 As shown, the first active member 211 is also provided with a first notch 2113. The first notch 2113 is opposite to the first arc-shaped structure 2111 and is located on both radial sides of the first active member 211. The first notch 2113 is used to allow the second limiting part 2214 to pass through during rotation, thereby releasing the first driven member 221 from the limit.

[0088] Specifically, the first active member 211 is columnar, with one end connected to the first driving member 212 and the other end extending to the other side of the first driven member 221, where a cam plate is provided radially. That is, the two ends of the first active member 211 are located on both sides of the first driven member 221, and the cam plate and the first driving member 212 are located on both sides of the first driven member 221. The cam plate protrudes toward the first driven member 221 and provides the sliding shaft 214 as the first driving part 2112. The first active member 211 has the first arc-shaped structure 2111 and the first notch 2113 on its radial sides corresponding to the first driven member 221, respectively. The direction of the cam plate protrusion corresponds to the first notch 2113, and both are located on the same radial side of the first active member 211. When the first driving member 212 drives the first active member 211 to rotate, the first arc-shaped structure 2111, the first driving part 2112, and the first notch 2113 rotate coaxially. Taking the driving and unlocking process as an example, during the rotation, the first driving part 2112 rotates into the slide groove 2212 to drive the first driven member 221 to rotate. Part of the second limiting part 2214 of the first driven member 221 passes through the first notch 2113, and the first arc-shaped structure 2111 separates from the arc-shaped groove structure 2211 to release the limiting. In this embodiment, the first arc-shaped structure 2111 and the first notch 2113 simultaneously realize the limiting or unlocking of the first driven member 221, preventing the first driven member 221 and the first active member 211 from interfering with each other during the rotation. The structure is simple and not prone to failure.

[0089] Preferred, such as Figure 1As shown, the photoelectric mechanism 3 of this embodiment includes a first sensor 31, a second sensor 32, a third sensor 33, and a fourth sensor 34. The first sensor 31 is used to sense the position of the product 5 on the transmission belt. The photoelectric mechanism 3 includes multiple first sensors 31, which are spaced apart on the fixed beam 41 of the fixing mechanism 4. Each first sensor 31 includes a first loading sensor 311 and a first unloading sensor 312. Specifically, the first sensor 31 includes two first loading sensors 311 and is located on the side where the transmission mechanism 1 transmits the product 5 to the flipping mechanism 2, i.e., the loading side. The first unloading sensor 312 is located on the side where the transmission mechanism 1 transmits the flipped product 5, i.e., the unloading side. The first sensor 31 is used to sense the position of the product 5 on the transmission belt and transmits a signal to the controller. The first sensor 31 can also be used to sense whether multiple products 5 are piled up on the transmission mechanism 1. The second sensor 32 is disposed on the loading side of the turntable mechanism 22 and close to the second driven member 222, and is used to sense whether the product 5 is clamped by the turntable mechanism 22 and to transmit a signal to the controller. The third sensor 33 is disposed on the unloading side of the turntable mechanism 22 and close to the second driven member 222, and is used to sense whether the product 5 leaves the turntable mechanism 22 and to transmit a signal to the controller. The fourth sensor 34 is disposed on the active mechanism 21 and is used to sense the position of the sliding shaft 214 of the first active member 211 and transmit a signal to the controller. That is, the fourth sensor 34 senses the position where the sliding shaft 214 of the first active member 211 rotates to contact the edge of the slide groove 2212 or is about to separate from the edge of the slide groove 2212, detects the sliding shaft 214 rotating into or out of the slide groove 2212, and transmits the above signal to the controller. The controller transmits a running signal or a stop signal to the active mechanism 21 and / or the transmission mechanism 1 based on the signals transmitted by the first sensor 31, and / or the second sensor 32, and / or the third sensor 33, and / or the fourth sensor 34. Of course, multiple second sensors 32 and third sensors 33 can also be provided.

[0090] Preferably, the first sensing element 31, the second sensing element 32, the third sensing element 33, and the fourth sensing element 34 are sensors. Specifically, the first sensing element 31, the second sensing element 32, and the third sensing element 33 are photoelectric sensors. The fourth sensing element 34 is a proximity switch.

[0091] Preferably, the drive mounting plate 213 is provided with a sensor bracket 341, and a fourth sensor 34 is provided on the sensor bracket 341.

[0092] Preferably, the first unloading sensor 312 is disposed on the side of the third sensor 33 away from the second sensor 32.

[0093] Preferably, the controller includes a PLC controller or an MCU processor, and is electrically connected to the active mechanism 21, the photoelectric mechanism 3, and the transmission mechanism 1. Specifically, the controller receives signals from the first sensor 31, the second sensor 32, the third sensor 33, and the fourth sensor 34, and transmits control signals to the active mechanism 21 and the transmission mechanism 1. It should be noted that the first drive unit 212, the second drive unit, the third drive unit, the fourth drive unit, and the fifth drive unit are motors, but they can also be hydraulic or other drive structures. The photoelectric mechanism 3 is not mandatory; it does not detect the position of the product 5. The turntable mechanism 22 directly waits for the product 5 to enter. If the product 5 does not correspond to the receiving slot of the turntable mechanism 22, the product 5 will collide with the side wall of the turntable mechanism 22 for limiting.
