[0043] To make the objectives, features, and advantages of this application more readily apparent, the present application is further described below in conjunction with the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without inventive effort are also within the scope of protection of this application.

[0044] Reference Figures 1-10 , shows a schematic structural diagram of a double-sided drive double-station alternating loading and unloading device of the present invention, which may specifically include:

[0045] The frame structure 1 includes two mounting bases 11 disposed opposite each other. Each mounting base 11 is provided with a drive mechanism 2 and two sets of transmission mechanisms 3. The transmission mechanisms 3 of the two mounting bases 11 are synchronized via a main transmission shaft 31. The drive mechanism 2 is connected to one set of transmission mechanisms 3 of the corresponding mounting base 11.

[0046] Two carrier assemblies 4 are arranged in layers between two mounting substrates 11 and are respectively arranged to slide horizontally with the two mounting substrates 11; the carrier assemblies 4 include:

[0047] Two first movable plates 41 are arranged opposite to each other, and the two first movable plates 41 are respectively connected to two opposite sets of transmission mechanisms 3;

[0048] The tray 42 and two second movable plates 43 are arranged opposite to each other, and the tray 42 is connected between the two second movable plates 43; the two second movable plates 43 are respectively arranged to slide horizontally on the inner sides of the two first movable plates 41, and are driven to slide by the movable pulley mechanism 5 embedded in the first movable plates 41.

[0049] In the embodiment of the present application, two carrier assemblies 4 are arranged in layers between two relatively arranged mounting bases 11, a driving mechanism 2 and two sets of transmission mechanisms 3 are arranged on each mounting base 11, and the relative transmission mechanisms 3 are synchronized through the main transmission shaft 31. The driving mechanism 2 drives one set of transmission mechanisms 3 of the corresponding mounting plate 25 to operate, and can synchronously drive the transmission mechanism 3 on the relative mounting plate 25 to operate, thereby providing driving force for both ends of the two carrier assemblies 4; by setting the driving direction of the two driving mechanisms 2, the two carrier assemblies 4 can be alternately extended and retracted, thereby realizing alternating loading and unloading of double-stations; the carrier assembly 4 includes a first movable plate 41 arranged relatively to each other, and the first movable plate 41 and the transmission mechanism 3 are connected to each other. The first movable plate 41 is connected and is driven by the transmission mechanism 3 to move horizontally, so as to extend to both sides and reset to the middle; a second movable plate 43 is slidingly provided on the inner side of the first movable plate 41, and the two second movable plates 43 are connected by a tray 42 to realize the loading of materials; the second movable plate 43 is driven to slide by the movable pulley mechanism 5 embedded in the first movable plate 41, and when the first movable plate 41 moves horizontally, it drives the movable pulley mechanism 5 to operate, and the movable pulley mechanism 5 drives the second movable plate 43 to move horizontally, that is, when the driving mechanism 2 drives the first movable plate 41 to move horizontally, it can synchronously drive the second movable plate 43 to move horizontally, thereby increasing the extending length of the carrier assembly 4, and when retracted, the two are stacked on the inner side of the mounting base plate 11, which does not take up space, has a small size and low cost.

[0050] Next, a double-sided drive double-station alternating loading and unloading device in this exemplary embodiment will be further described.

[0051] In the examples of this application, refer to Figure 1 and Figure 2 The frame structure 1 is composed of two mounting base plates 11 arranged opposite to each other and a plurality of transverse plates 12 connecting the two mounting base plates 11. The plurality of transverse plates 12 are respectively connected to the top and bottom of the mounting base plates 11 so as not to affect the operation of the carrier assembly 4 between the mounting base plates 11. Each mounting base plate 11 is provided with a driving mechanism 2 and two sets of transmission mechanisms 3. The two sets of transmission mechanisms 3 on the two mounting base plates 11 are arranged opposite to each other. The relative transmission mechanisms 3 are synchronized by the main transmission shaft 31, so that both ends of the carrier assembly 4 have driving force. The driving mechanism 2 is connected to one of the transmission mechanisms 3 of the corresponding mounting base plate 11, that is, when the driving mechanism 2 drives the transmission mechanism 3 to operate, the transmission mechanism 3 drives the transmission mechanism 3 on the opposite side to operate synchronously through the main transmission shaft, so that the two relative transmission mechanisms 3 can synchronously drive the corresponding carrier assembly 4 to slide on the mounting base plate 11, so that it can extend and retract to both sides.

[0052] As an example, see Figure 3The drive mechanism 2 comprises a servo motor 21, a drive pulley 22, a driven pulley 23, and a drive belt 24. The servo motor 21 is mounted on top of the mounting base 11 via a mounting plate 25. Specifically, the tops of the two mounting bases 11 are each fixedly connected to a mounting plate 25, which supports the drive mechanism 2 and the main transmission shaft 31. The two main transmission shafts 31 are disposed opposite each other, with their ends mounted to the mounting plates 25 via bearing blocks 26. The drive pulley 22 is sleeved onto the output shaft of the servo motor 21, and the driven pulley 23 is sleeved onto the corresponding main transmission shaft 31. The drive belt 24 is sleeved onto the exterior of the drive pulley 22 and the driven pulley 23.

[0053] During actual operation, the servo motor 21 drives the driving wheel 22 to rotate, and the driving wheel 22 drives the driven wheel 23 to rotate synchronously through the driving belt 24. The driven wheel 23 drives the main transmission shaft 31 to rotate, so that the two ends of the main transmission shaft 31 respectively drive the two transmission mechanisms 3 to operate synchronously.

[0054] Specifically, the driving wheel 22, the driven wheel 23 and the driving belt 24 are preferably connected in a gear and toothed belt meshing manner, which has high mechanical strength, high transmission accuracy and transmission efficiency, and reliable operation.

[0055] As an example, see Figure 3 and Figure 4 The transmission mechanism 3 includes a first transmission wheel 32, a second transmission wheel 33, a third transmission wheel 34, a fourth transmission wheel 35, a first transmission belt 36 and a transmission toothed belt 37; the first transmission wheel 32 is sleeved on the end of the main transmission shaft 31; the second transmission wheel 33 is arranged on the outer side of the mounting base 11 and is connected to the first transmission wheel 32 through the first transmission belt 36; that is, the rotation of the main transmission shaft 31 can drive the first transmission wheels 32 at both ends thereof to rotate, thereby driving the first transmission belt 36 to rotate and driving the second transmission wheel 33 to rotate synchronously.

[0056] The third and fourth transmission wheels 34, 35 are each horizontally mounted on the inner side of the mounting base 11 via a secondary transmission shaft 38. The third transmission wheel 34 faces the second transmission wheel 33 and is respectively mounted on both ends of the corresponding secondary transmission shaft 38. The secondary transmission shaft 38 is rotatably mounted through the mounting base 11. A transmission toothed belt 37 is mounted on the exterior of the third and fourth transmission wheels 34, 35. Rotation of the second transmission wheel 33 drives the secondary transmission shaft 38 connected to it, which in turn drives the third transmission wheel 34. The third transmission wheel 34 then drives the fourth transmission wheel 35 via the transmission toothed belt 37. The transmission toothed belt 37 is connected to the carrier assembly 4 to drive the carrier assembly 4 horizontally.

[0057] It should be noted that the two sets of transmission mechanisms 3 on the same mounting substrate 11 correspond to the heights of the two carrier assemblies 4 arranged in the upper and lower layers respectively; that is, the lengths of the first transmission belts 36 of the two transmission mechanisms 3 are different, one of them is shorter, so that the transmission toothed belt 37 connected to it is located in the middle of the mounting substrate 11, and the other is longer, so that the transmission toothed belt 37 connected to it is located at the lower part of the mounting substrate 11, so that the two transmission toothed belts 37 will not interfere with each other, and can also be connected to the two carrier assemblies 4 arranged in the upper and lower layers respectively.

[0058] As an example, see Figure 1 and Figure 5 The mounting base plate 11 is provided with an adjusting structure 6 , which is arranged opposite to the fourth transmission wheel 35 ; the adjusting structure 6 is used to adjust the tension of the transmission toothed belt 37 .

[0059] Specifically, the adjustment structure 6 includes a moving block 61, an adjustment frame 62, and an adjustment screw 63. The adjustment frame 62 is mounted within a horizontally defined strip hole 13 on the sidewall of the mounting base 11. The moving block 61 is mounted via a bearing sleeve on the end of the secondary transmission shaft 38 connected to the fourth transmission wheel 35. The moving block 61 is slidably disposed within the adjustment frame 62, and both ends of the moving block 61 are connected to the adjustment frame 62 via adjustment screws 63. During adjustment, by loosening the nut on the adjustment screw 63, the moving block 61 can move left and right within the adjustment frame 62, thereby driving the connected secondary transmission shaft 38 to move left and right, causing the fourth transmission wheel 35 at the other end of the secondary transmission shaft 38 to move left and right, thereby adjusting the tension of the transmission belt 37. After adjusting to the appropriate position, the adjustment screw 63 can be fixed. The strip hole 13 defined in the mounting base 11 not only facilitates the installation of the adjustment structure 6 and reduces the space required, but also creates space for the secondary transmission shaft 38 to move left and right.

[0060] As an example, see Figure 1 and Figure 6 Two sets of tensioning structures 7 are provided on the outside of the mounting base 11, one on each side of the two first transmission belts 36, for adjusting the tension of the first transmission belts 36. Specifically, the tensioning structure 7 includes a connecting block 71 and a tensioning pulley 72. The connecting block 71 is movably mounted on the mounting base 11, and the tensioning pulley 72 is rotatably mounted on the connecting block 71. The connecting block 71 can be connected and adjusted by providing a waist hole therein and a mounting hole on the mounting base 11, and the connection is locked with a locking bolt. To adjust, loosen the locking bolt, move the connecting block 71 toward the first transmission belt 36 until the tensioning pulley 72 is pressed against the first transmission belt 36, and then tighten the locking bolt.

[0061] In the examples of this application, refer to Figure 2The carrier assembly 4 comprises two first movable plates 41 arranged opposite to each other, a tray 42 and two second movable plates 43 arranged opposite to each other. The two first movable plates 41 are respectively connected to two opposite sets of transmission mechanisms 3, that is, they are connected to the transmission toothed belts 37 of corresponding heights. The tray 42 is connected between the two second movable plates 43 to achieve material loading. The two second movable plates 43 are respectively arranged to slide horizontally on the inner sides of the two first movable plates 41 and are driven to slide by the movable pulley mechanism 5 embedded in the first movable plates 41. The movable pulley driving mechanism 2 is respectively connected to the mounting base 11 and the second movable plate 43. When the first movable plate 41 moves horizontally, it drives the movable pulley mechanism 5 to operate, and the movable pulley mechanism 5 drives the second movable plate 43 to move horizontally. That is, when the driving mechanism 2 drives the first movable plate 41 to move horizontally, it can also drive the second movable plate 43 to move horizontally, thereby increasing the extended length of the carrier assembly 4. When retracted, the two are stacked on the inner side of the mounting base 11, which does not take up space, has a small volume and low cost.

[0062] Furthermore, the first movable plate 41 and the mounting substrate 11 as well as the first movable plate 41 and the second movable plate 43 can be connected by a slide rail, which can guide and support the horizontal movement of the first movable plate 41 and the second movable plate 43, making the horizontal movement of the first movable plate 41 and the second movable plate 43 more stable.

[0063] As an example, see Figure 4 and Figure 5 The bottom of the first movable plate 41 is provided with a tooth portion 411 along its length direction, and the tooth portion 411 is provided above the transmission toothed belt 37 and meshes with it.

[0064] It should be noted that the transmission toothed belt 37 has teeth on both sides of the belt body. The third transmission wheel 34 and the fourth transmission wheel 35 are gears meshed with the transmission toothed belt 37. The teeth on the inner side of the transmission toothed belt 37 mesh with the third transmission wheel 34 and the fourth transmission wheel 35, and the teeth on the outer side mesh with the first movable plate 41, so that the first movable plate 41 can be driven to move efficiently, accurately and stably.

[0065] As an example, see Figure 4 The mounting base 11 is further embedded with a support block 14, which extends to the inner side of the transmission toothed belt 37 and supports the upper toothed belt of the transmission toothed belt 37. The support block 14 is strip-shaped and is fixedly connected to the mounting base 11 via a fixing frame provided on the outer side of the mounting base 11. It is used to support the transmission toothed belt 37 and, in turn, the first movable plate 41, thereby preventing the transmission toothed belt 37 from collapsing due to its flexibility.

[0066] As an example, see Figure 7-9The above-mentioned movable pulley mechanism 5 includes a second transmission belt 51 and a rotating wheel 52 rotatably embedded in the end of the first movable plate 41. The second transmission belt 51 is wound around both sides of the first movable plate 41 and is sleeved on the rotating wheel 52. The two ends of the second transmission belt 51 are respectively connected to the mounting base plate 11 and the second movable plate 43 through the clamping structure 8. The end of the second transmission belt 51 is fixed by the clamping structure 8, and the rotating wheel 52 is sleeved on the inner side of the second transmission belt 51. Since the mounting base 11 always remains fixed, the second movable plate 43 is slidably set on the first movable plate 41, so that the above structure constitutes a movable pulley mechanism 5, that is, when the first movable plate 41 moves horizontally under the drive of the driving mechanism 2, it will drive the rotating wheel 52 to move synchronously. Since one end of the second transmission belt 51 is fixed to the mounting base 11 by the clamping structure 8, the second transmission belt 51 and the rotating wheel 52 rotate relative to each other, and the second transmission belt 51 pulls the other end thereof fixed to the second movable plate 43 to move synchronously, thereby causing the second movable plate 43 to slide on the first movable plate 41, thereby realizing the extension and retraction between the first movable plate 41 and the second movable plate 43.

[0067] Preferably, two groups of the above-mentioned movable pulley structures are provided, which are respectively embedded in the first movable plate 41 at upper and lower intervals. The two rotating wheels 52 of the two groups of movable pulley structures are respectively provided close to the two ends of the first movable plate 41, that is, the rotation directions of the two movable pulley structures are opposite. In this way, stable sliding of the second movable plate 43 can be achieved when the carrier assembly 4 extends to both sides.

[0068] It should be noted that the rotating wheel 52 and the second transmission belt 51 are also preferably a gear and toothed belt structure.

[0069] Further, refer to Figure 10 The clamping structure 8 comprises a fixed block 81 and a tooth block 82 positioned opposite each other. One side of the fixed block 81 is fixedly connected to the mounting base plate 11 / second movable plate 43. One end of the tooth block 82 also extends and is fixed to the mounting base plate 11 / second movable plate 43. The tooth block 82 has teeth on the side facing the fixed block 81 and meshes with the second transmission belt 51, clamping the second transmission belt 51 between the fixed block 81 and the tooth block 82. During the rotation of the second transmission belt 51, its ends are always clamped and fixed by the clamping structure 8.

[0070] As an example, see Figure 2 、 Figure 3 and Figure 9The side wall of the mounting substrate 11 is provided with a plurality of photoelectric switches 15, and the first movable plate 41 is provided with a plurality of induction plates 16 respectively located at the same horizontal plane as the plurality of photoelectric switches 15; the photoelectric switches 15 are used to detect the origin position and the limit position of the carrier assembly 4 when extended to both sides. Specifically, two groups of photoelectric switches 15 are provided, one above the other, corresponding to the two carrier assemblies 4, for independently detecting the positions of the two carrier assemblies 4. Each group of photoelectric switches 15 is provided with two limit position detection switches and one origin position detection switch, and the two limit position detection switches are provided at positions near both ends of the mounting substrate 11. The first movable plate 41 is provided with an induction plate 16 on the same horizontal plane as the limit position detection switch, for detecting the limit position of the carrier assembly 4 when extended to both sides, to avoid extending beyond the end of the transmission toothed belt 37 and causing disengagement; specifically, when the first movable plate 41 extends to the left or right to the limit position, the induction plate is located at the photoelectric switch 15 at the left or right end, thereby sending a signal to the control system. The origin position detection switch is set at a position between the two extreme position detection switches so as not to interfere with them. A sensing plate is also set on the same horizontal plane as the first movable plate 41 and the origin position detection switch to detect whether the carrier assembly 4 is at the origin position, that is, retracted to the middle position of the mounting substrate 11; specifically, when the first movable plate 41 retracts to the middle position, the sensing plate is located at the origin photoelectric switch 15.

[0071] As an example, see Figure 9 The first movable plate 41 is embedded with a reserved wiring drag chain 17 near its bottom along its length direction. The reserved wiring drag chain 17 is used for routing. When the device is connected to multiple other devices, routing through the reserved wiring drag chain 17 can avoid line confusion and entanglement, which affects the operation of the carrier component 4.

[0072] As an example, see Figure 2 A material tray positioning pin 421 is further provided at one end of the tray 42 for positioning and fixing the material tray.

[0073] In one embodiment, two drive mechanisms 2 respectively drive the upper and lower trays 42 to extend to the manual operation side. After the operator removes the finished product from tray 42, the material is loaded onto tray 42. Tray 42 then retracts to a neutral position for waiting. The rear tray 42 automatically extends to the robot side, where the robot removes the material from tray 42 and places it into the processing machine. The robot then places the finished product back onto tray 42. The system then operates automatically, with the upper and lower levels alternating according to the aforementioned process. This significantly improves material loading and unloading efficiency, and the device is compact, small, and relatively low-cost.
