[0018] To make the objectives, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific implementation manners. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application. Referring to Figures 1 - 10 , a schematic diagram of the structure of a bilateral drive double-station alternating loading and unloading device of the present invention is shown, which specifically may include: Frame structure 1, including two oppositely arranged mounting substrates 11; each mounting substrate 11 is provided with a driving mechanism 2 and two sets of transmission mechanisms 3, and the transmission mechanisms 3 on the two oppositely arranged mounting substrates 11 are synchronously operated through a main transmission shaft 31; the driving mechanism 2 is connected to one set of the transmission mechanisms 3 of the corresponding mounting substrate 11; Two carrier components 4, the two carrier components 4 are arranged in upper and lower layers between the two mounting substrates 11 and are respectively horizontally slidably arranged with the two mounting substrates 11; the carrier component 4 includes: Two oppositely arranged first moving plates 41, and the two first moving plates 41 are respectively connected to the two sets of opposite transmission mechanisms 3; A tray 42 and two oppositely arranged second moving plates 43, the tray 42 is connected between the two second moving plates 43; the two second moving plates 43 are respectively horizontally slidably arranged inside the two first moving plates 41 and are driven to slide by a movable pulley mechanism 5 embedded in the first moving plate 41.

[0019] In the embodiment of the present application, by arranging two carrier components 4 in upper and lower layers between two oppositely arranged mounting substrates 11, arranging a driving mechanism 2 and two sets of transmission mechanisms 3 on each mounting substrate 11, the opposite transmission mechanisms 3 are synchronously operated through a main transmission shaft 31, and the driving mechanism 2 drives one set of the transmission mechanisms 3 of the corresponding mounting plate 25 to operate, so as to synchronously drive the transmission mechanisms 3 on the opposite mounting plate 25 to operate, thereby being able to provide driving forces for both ends of the two carrier components 4; by setting the driving directions of the two driving mechanisms 2, the two carrier components 4 can be alternately extended and retracted, thereby realizing double-station alternating loading and unloading; the carrier component 4 includes oppositely arranged first moving plates 41, and the first moving plates 41 are connected to the transmission mechanisms 3, and the first moving plates 41 are driven to move horizontally by the transmission mechanisms 3 to realize extending outwards on both sides and resetting towards the middle; the second moving plates 43 are slidably arranged inside the first moving plates 41, and the two second moving plates 43 are connected by a tray 42 to realize the loading of materials; the second moving plates 43 are driven to slide by the movable pulley mechanism 5 embedded in the first moving plates 41. When the first moving plates 41 move horizontally, the movable pulley mechanism 5 is driven to operate, and the movable pulley mechanism 5 drives the second moving plates 43 to move horizontally, that is, when the driving mechanism 2 drives the first moving plates 41 to move horizontally, the second moving plates 43 can be synchronously driven to move horizontally, increasing the extending length of the carrier component 4, and when contracting, the two are stacked inside the mounting substrate 11, taking up no space, being small in volume and low in cost.

[0020] Next, a double-sided driving double-station alternating loading and unloading device in the present exemplary embodiment will be further described.

[0021] In the embodiment of the present application, with reference to Figure 1 and Figure 2The frame structure 1 is composed of two mounting substrates 11 arranged opposite to each other and a plurality of transverse plates 12 connecting the two mounting substrates 11. The plurality of transverse plates 12 are respectively connected to the top and bottom of the mounting substrates 11 so as not to affect the operation of the carrier assembly 4 between the mounting substrates 11. Each mounting substrate 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 substrates 11 are arranged opposite to each other. The relative transmission mechanisms 3 are synchronized through 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 set of transmission mechanisms 3 of the corresponding mounting substrate 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 substrate 11, so as to extend and retract it to both sides.

[0022] As an example, see Figure 3 The driving mechanism 2 comprises a servo motor 21, a driving wheel 22, a driven wheel 23 and a driving belt 24. The servo motor 21 is mounted on the top of the mounting base plate 11 through a mounting plate 25; that is, the tops of the two mounting base plates 11 are respectively fixedly connected with mounting plates 25 for supporting the driving mechanism 2 and the main transmission shaft 31. The two main transmission shafts 31 are arranged opposite to each other and their two ends are respectively mounted on the mounting plates 25 through bearing seats 26. The driving wheel 22 is sleeved on the output shaft of the servo motor 21, and the driven wheel 23 is sleeved on the corresponding main transmission shaft 31; the driving belt 24 is sleeved on the outside of the driving wheel 22 and the driven wheel 23.

[0023] In 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, and 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.

[0024] 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.

[0025] 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 plate 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.

[0026] The above-mentioned third driving wheel 34 and fourth driving wheel 35 are horizontally arranged inside the mounting substrate 11 through the auxiliary transmission shaft 38 respectively; wherein, the third driving wheel 34 is opposite to the second driving wheel 33 and is sleeved at both ends of the corresponding auxiliary transmission shaft 38 respectively; the auxiliary transmission shaft 38 rotates through the mounting substrate 11; the transmission belt 37 is sleeved outside the third driving wheel 34 and the fourth driving wheel 35. That is, when the second driving wheel 33 rotates, it drives the auxiliary transmission shaft 38 connected thereto to rotate, and then drives the third driving wheel 34 to rotate. The third driving wheel 34 drives the fourth driving wheel 35 to rotate through the transmission belt 37. The transmission belt 37 is used to connect with the carrier assembly 4 to drive the carrier assembly 4 to move horizontally.

[0027] 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 is shorter, so that the transmission belt 37 connected thereto is located in the middle of the mounting substrate 11, and the other is longer, so that the transmission belt 37 connected thereto is located at the lower part of the mounting substrate 11, so as to ensure that the two transmission belts 37 do not interfere with each other and can be respectively connected to the two carrier assemblies 4 arranged in the upper and lower layers.

[0028] As an example, referring to Figure 1 and Figure 5 , the above-mentioned mounting substrate 11 is provided with an adjusting structure 6, and the adjusting structure 6 is arranged opposite to the fourth driving wheel 35; the adjusting structure 6 is used to adjust the tension of the transmission belt 37.

[0029] Specifically, the above-mentioned adjusting structure 6 includes a moving block 61, an adjusting frame 62 and an adjusting screw 63. The adjusting frame 62 is installed in the strip-shaped hole 13 horizontally opened on the side wall of the mounting substrate 11. The moving block 61 is sleeved on the end of the auxiliary transmission shaft 38 connected to the fourth driving wheel 35 through a bearing; the moving block 61 is slidably arranged in the adjusting frame 62, and both ends of the moving block 61 are respectively connected to the adjusting frame 62 through the adjusting screw 63. During adjustment, by loosening the nut on the adjusting screw 63, the moving block 61 can move left and right in the adjusting frame 62, and then drive the auxiliary transmission shaft 38 connected thereto to move left and right, so that the fourth driving wheel 35 at the other end of the auxiliary transmission shaft 38 moves left and right, realizing the adjustment of the tension of the transmission belt 37. After adjusting to the appropriate position, fix the adjusting screw 63. Through the strip-shaped hole 13 opened on the mounting substrate 11, it is not only convenient for the installation of the adjusting structure 6, reduces the space volume, but also forms a space for the left and right movement of the auxiliary transmission shaft 38.

[0030] As an example, referring to Figure 1 and Figure 6, two sets of tensioning structures 7 are provided on the outer side of the above-mentioned mounting substrate 11, and are respectively arranged on one side of two first drive belts 36; used to adjust the tension of the first drive belts 36. Specifically, the tensioning structure 7 includes a connecting block 71 and a tensioning wheel 72. The connecting block 71 is movably mounted on the mounting substrate 11, and the tensioning wheel 72 is rotatably arranged on the connecting block 71. The above-mentioned connecting block 71 can be connected and adjusted by a structure of opening a waist hole on it and an installation hole on the mounting substrate 11 and locking and connecting with a locking bolt. During adjustment, loosen the locking bolt, move the connecting block 71 towards the first drive belt 36 until the tensioning wheel 72 abuts against the first drive belt 36, and then tighten the locking bolt.

[0031] In the embodiment of the present application, referring to Figure 2 , the above-mentioned carrier assembly 4 includes two first moving plates 41 arranged oppositely, a tray 42 and two second moving plates 43 arranged oppositely. The two first moving plates 41 are respectively connected to two sets of opposite transmission mechanisms 3; that is, connected to the transmission toothed belts 37 at corresponding heights. The tray 42 is connected between the two second moving plates 43 to realize the loading of materials; the two second moving plates 43 are respectively horizontally slidably arranged inside the two first moving plates 41 and are driven to slide by a movable pulley mechanism 5 embedded in the first moving plates 41. The movable pulley driving mechanism 2 is respectively connected to the mounting substrate 11 and the second moving plates 43. When the first moving plates 41 move horizontally, the movable pulley mechanism 5 is driven to operate, and the movable pulley mechanism 5 drives the second moving plates 43 to move horizontally. That is, when the driving mechanism 2 drives the first moving plates 41 to move horizontally, the second moving plates 43 can be synchronously driven to move horizontally, thereby increasing the extended length of the carrier assembly 4, and when contracting, the two are stacked inside the mounting substrate 11, occupying no space, having a small volume and low cost.

[0032] Furthermore, the first moving plates 41 and the mounting substrate 11 and between the first moving plates 41 and the second moving plates 43 can be connected by slide rails, which can play a guiding and supporting role in the horizontal movement of the first moving plates 41 and the second moving plates 43, making the horizontal movement of the first moving plates 41 and the second moving plates 43 more stable.

[0033] As an example, referring to Figure 4 and Figure 5 , a tooth portion 411 is arranged along the length direction at the bottom of the above-mentioned first moving plate 41. The tooth portion 411 is arranged above the transmission toothed belt 37 and meshes with it.

[0034] It should be noted that both the inner and outer sides of the belt body of the above-mentioned drive belt 37 have teeth. The above-mentioned third drive wheel 34 and fourth drive wheel 35 are gears meshing with the drive belt 37. The teeth on the inner side of the drive belt 37 mesh with the third drive wheel 34 and the fourth drive wheel 35, and the teeth on the outer side mesh with the first moving plate 41, enabling the first moving plate 41 to be driven to move efficiently, precisely, and stably.

[0035] As an example, referring to Figure 4 , the above-mentioned mounting substrate 11 is also embedded with a support block 14. The support block 14 extends to the inner side of the drive belt 37 and supports the upper belt of the drive belt 37. The above-mentioned support block 14 is strip-shaped and is fixedly connected to the mounting substrate 11 through a fixing frame arranged on the outer side of the mounting substrate 11, used to support the drive belt 37, and thus can support the first moving plate 41, and can avoid problems such as the softness of the drive belt 37 collapsing.

[0036] As an example, referring to Figures 7 - 9 , the above-mentioned movable pulley mechanism 5 includes a second drive belt 51 and a rotating wheel 52 rotatably embedded at the end of the first moving plate 41. The second drive belt 51 is wound around both sides of the first moving plate 41 and sleeved on the rotating wheel 52. Both ends of the second drive belt 51 are respectively connected to the mounting substrate 11 and the second moving plate 43 through a clamping structure 8. The end of the second drive belt 51 is fixed through the clamping structure 8, and the rotating wheel 52 is sleeved on the inner side of the second drive belt 51. Since the mounting substrate 11 always remains fixed and the second moving plate 43 is slidably arranged on the first moving plate 41, the above-mentioned structure then constitutes the movable pulley mechanism 5, that is, when the first moving plate 41 moves horizontally under the drive of the drive mechanism 2, it will drive the rotating wheel 52 to move synchronously. Since one end of the second drive belt 51 is fixed to the mounting substrate 11 through the clamping structure 8, relative rotation occurs between the second drive belt 51 and the rotating wheel 52, and the second drive belt 51 pulls the other end fixed to the second moving plate 43 to move synchronously, thereby enabling the second moving plate 43 to slide on the first moving plate 41 and realizing the telescoping between the first moving plate 41 and the second moving plate 43.

[0037] Preferably, two sets of the above-mentioned movable pulley structures are provided, which are respectively embedded on the first moving plate 41 at intervals up and down. The two rotating wheels 52 of the two movable pulley structures are respectively arranged close to both ends of the first moving plate 41, that is, the rotation directions of the two movable pulley structures are opposite. In this way, stable sliding of the second moving plate 43 can be realized when the carrier assembly 4 extends to both sides.

[0038] It should be noted that the above-mentioned rotating wheel 52 and the second drive belt 51 are also preferably a gear and a toothed belt structure.

[0039] Furthermore, referring to Figure 10, the above clamping structure 8 includes a fixed block 81 and a toothed block 82 which are arranged oppositely. One side of the fixed block 81 is fixedly connected to the mounting substrate 11 / the second moving plate 43; one end of the toothed block 82 also extends and is fixed on the mounting substrate 11 / the second moving plate 43. The side of the toothed block 82 facing the fixed block 81 has teeth and meshes with the second transmission belt 51 to clamp the second transmission belt 51 between the fixed block 81 and it. During the rotation of the second transmission belt 51, its two ends are always clamped and fixed by the clamping structure 8.

[0040] As an example, referring to Figure 2 , Figure 3 and Figure 9 , a plurality of photoelectric switches 15 are arranged on the side wall of the above mounting substrate 11, and a plurality of induction plates 16 which are respectively in the same horizontal plane as the plurality of photoelectric switches 15 are arranged on the first moving plate 41; the photoelectric switches 15 are used to detect the origin position and the extreme positions extending to both sides of the carrier assembly 4. Specifically, two sets of photoelectric switches 15 are respectively arranged, corresponding to the two carrier assemblies 4, for independently detecting the positions of the two carrier assemblies 4. Each set of photoelectric switches 15 is provided with two extreme position detection switches and one origin position detection switch. The two extreme position detection switches are arranged at positions close to both ends of the mounting substrate 11. An induction plate 16 is arranged on the first moving plate 41 in the same horizontal plane as the extreme position detection switch for detecting the extreme positions when the carrier assembly 4 extends to both sides, so as to avoid extending beyond the end of the transmission toothed belt 37 and causing disengagement; specifically, when the first moving plate 41 extends to the left or right extreme position, the induction plate is located at the photoelectric switch 15 at the left end or the right end, thereby sending a signal to the control system. The origin position detection switch is arranged at a position between the two extreme position detection switches above, so as not to interfere with it. An induction plate is also arranged on the first moving plate 41 in the same horizontal plane as the origin position detection switch for detecting whether the carrier assembly 4 is located at the origin position, that is, retracted to the middle position of the mounting substrate 11; specifically, when the first moving plate 41 retracts to the middle position, the induction plate is located at the origin photoelectric switch 15.

[0041] As an example, referring to Figure 9 , a reserved wiring drag chain 17 is embedded along the length direction near the bottom of the above first moving plate 41. The reserved wiring drag chain 17 is used for wiring. When the device is connected to other multiple devices, wiring through the reserved wiring drag chain 17 can avoid wire chaos and mutual entanglement, affecting the operation of the carrier assembly 4.

[0042] As an example, referring to Figure 2 , a material tray positioning pin 421 is further arranged at one end of the above tray 42 for positioning and fixing the material tray.

[0043] In a specific embodiment, two driving mechanisms 2 respectively drive the trays 42 on the upper and lower layers to extend to the manual operation side. After the finished products on the trays 42 are manually taken out, materials are then loaded into the trays 42. The trays 42 retract into the middle position and wait. Then the trays 42 automatically extend to the robot side, and the robot takes the materials on the trays 42 and puts them into the processing machine tool, and the robot puts the finished products back onto the trays 42. The system runs automatically, and the upper and lower layers work alternately according to the above process. This can greatly improve the efficiency of material loading and unloading, and the device has a compact structure, a small volume, and a relatively low cost.
