[0066] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0067] It should be noted that the directional terms such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0068] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the overall structure of the stacking tray loading and unloading device in the embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the assembly structure of the loading mechanism and the lifting mechanism in the stacking tray loading and unloading device shown; Figure 3 for Figure 1 The schematic diagram of the structure of the tray separation mechanism in the stacking tray loading and unloading device shown; Figure 4 for Figure 3 A schematic diagram of the arrangement of the first non-return assembly, the second non-return assembly and the lifting and separating assembly in the tray separation mechanism; Figure 5 for Figure 1 The diagram shows the structure of the grabbing and feeding mechanism in the stacking tray loading and unloading device.

[0069] The stacking tray loading and unloading device provided in the embodiment of the present application includes a loading mechanism 1, a lifting mechanism 2, a tray separating mechanism 3 and a grabbing and feeding mechanism 4.

[0070] Among them, the loading mechanism 1 is used to transport the stacked material tray 5 filled with materials to the loading position, and the loading position is located above the initial position of the jacking mechanism 2. The jacking mechanism 2 lifts the stacked material tray 5 located at the loading position to the material separation position through the upward movement. The material separation position is located in the separation tray mechanism 3. The separation tray mechanism 3 is used to separate the material trays in the stacked material tray 5 one by one. Furthermore, the separation tray mechanism 3 includes a separation bin 31, a first non-return component 32, a second non-return component 33 and a lifting separation component 34. The separation bin 31 is located above the loading position, and the first non-return component 32 is located in the separation bin 31. The first non-return component 32 is used to support the separated material trays and the material tray that has completed material removal, the second check component 33 is arranged in the separation bin 31, the second check component 33 is located above the first check component 32, the second check component 33 is used to stack the material trays that have completed material removal, the lifting and separation component 34 is used to lift the top material tray at the material distribution position in the stacked material trays 5 to the first check component 32, and is used to lift the material tray on the first check component 32 to the second check component 33, the grabbing and feeding mechanism 4 is used to grab the material tray on the first check component 32, and transport the material tray to the working position, and the grabbing and feeding mechanism 4 is also used to transport the material tray that has completed material removal to the first check component 32.

[0071] After the material is loaded onto the loading and unloading device, the material tray 5 is loaded and the material is transported to the loading position. After the material is loaded onto the loading position, the material tray 5 is transported to the loading position. After the material is loaded onto the loading position, the material tray 5 is transported to the loading position. After the material is loaded onto the loading position, the material tray 5 is transported to the loading position. After the material is loaded onto the loading position, the material tray 5 is transported to the loading position. After the material is loaded onto the loading position, the material tray 5 is transported to the loading position. By repeating the above working process, the trays can be automatically stacked on the second non-return assembly 33. When the number of trays reaches a threshold, people will take away the stacked trays.

[0072] The stacking tray loading and unloading device provided in the embodiment of the present application mainly includes a lower loading area, a middle working area and an upper unloading area, and the lower loading area, the middle working area and the upper unloading area work independently, the overall operation is stable, and it is also convenient for staff to observe.

[0073] The stacking tray loading and unloading device provided in the embodiment of the present application can efficiently utilize the space size, realize automatic loading and unloading of the stacking tray 5, and at the same time provide stable and uniform feeding, thereby improving the degree of automation and production efficiency and reducing production costs.

[0074] In some embodiments, the loading mechanism 1 is specifically a pull-out loading mechanism, which includes a platform 11, a first linear guide rail 12 and a drawer 13, wherein the first linear guide rail 12 is arranged on the platform 11, the drawer 13 is used to load the stacked material tray 5, and the drawer 13 is used to slide along the first linear guide rail 12.

[0075] It can be seen that when loading materials, the drawer 13 is first pulled out to place the stacked material trays, and then the drawer 13 is pushed in until it reaches the loading position.

[0076] In some embodiments, the pull-out loading mechanism further includes a magnetic signal feedback member 14, a locking structure 15, and a locking cylinder 16, wherein the magnetic signal feedback member 14 is provided on the carrier 11, and the magnetic signal feedback member 14 is used to engage with the magnetic member on the drawer 13, the locking structure 15 is provided on the drawer 13, and the locking cylinder 16 is provided on the carrier 11, and the locking cylinder 16 is used to cooperate with the locking structure 15 after the magnetic signal feedback member 14 and the magnetic member are engaged, so as to fix the drawer 13. For example, after the drawer 13 is in place, the locking axis of the locking cylinder 16 extends upward and is inserted into the locking structure 15 (which may be a locking hole) at the bottom of the drawer 13 to achieve positioning of the drawer 13.

[0077] That is to say, when the drawer 13 equipped with the stacked material tray 5 reaches the loading position, the magnetic signal feedback component 14 can just engage with the magnetic component on the drawer 13, thereby feedbacking the signal to the locking cylinder 16, and the locking shaft of the locking cylinder 16 extends and cooperates with the locking hole on the locking structure 15 to lock, thereby achieving the purpose of fixing the drawer 13.

[0078] In addition, a limit block 17 may be provided on the carrier 11 , and the limit block 17 is used to prevent the drawer 13 from being separated from the carrier 11 when being drawn out.

[0079] In some embodiments, the lifting mechanism 2 includes a base plate 21, a screw rod 22, a lifting block 23, a lifting motor 24, and a guide shaft 25. The screw rod 22 is rotatably mounted on the base plate 21, and the lifting block 23 is mounted on the screw rod 22. Under the rotation of the screw rod 22, the lifting block 23 moves upward to lift the stacked material tray 5. The lifting motor 24 is connected to the screw rod 22 and is used to drive the screw rod 22 to operate. The guide shaft 25 is mounted on the base plate 21 and is used to pass through the lifting block 23 to guide the lifting block 23 during its movement.

[0080] In this way, after the drawer 13 brings the stacked material tray 5 to the loading position, the lifting motor 24 is started, the screw rod 22 is operated, and the stacked material tray 5 in the drawer 13 is lifted and moved upward to the material distribution position in the tray distribution mechanism 3 through the lifting block 23. Of course, the assembly of the screw rod 22 and the lifting block 23 can be referred to the ball screw module, and will not be elaborated here.

[0081] In some embodiments, the first check assembly 32 and the second check assembly 33 both include a first check seat 321 and a first check block 322, wherein the first check seat 321 is fixed on the inner wall of the separation bin 31, and the first check block 322 is flippably connected to the first check seat 321. During the upward movement of the stacked material tray 5, the stacked material tray 5 can contact the first check block 322, causing the first check block 322 to flip upward to avoid the material tray. After the material tray is in place, the first check block 322 can be quickly reset to support the material tray.

[0082] Of course, in order to facilitate the resetting of the first check block 322, an elastic member, such as a torsion spring, can also be provided. The torsion spring connects the first check block 322 and the first check seat 321. The torsion spring is used to provide elastic force to the first check block 322, so that the first check block 322 has a tendency to flip downward, that is, the first check block 322 has the function of resetting after flipping.

[0083] The number of the first check blocks 322 and the first check seats 321 is the same, and at least two pairs of them are provided.

[0084] Preferably, the number of the first check components 32 and the second check components 33 are two pairs, so that the first check components 32 are arranged on the inner wall of the separation bin 31 in pairs, and the second check components 33 are arranged on the inner wall of the separation bin 31 in pairs, thereby ensuring the stability of the support for the stacked material trays 5.

[0085] In some embodiments, the lifting and separation assembly 34 includes a second check seat 341, a second check block 342, a bracket 343, and a lifting drive assembly 344. The second check seat 341 is movably disposed on the separation bin 31, and the second check block 342 is reversibly connected to the second check seat 341. The second check block 342 is configured to flip upward to avoid the material tray, and the second check block 342 is configured to return to its original position after the material tray is in place to support the material tray. The bracket 343 is connected to the second check seat 341, and the lifting drive assembly 344 is connected to the bracket 343. The lifting drive assembly 344 is configured to provide power for up and down movement to drive the second check seat 341 and the second check block 342 to move up and down relative to the separation bin 31. Of course, the lifting drive assembly 344 can be a combination of a motor and a screw assembly.

[0086] The number of the second check blocks 342 and the second check seats 341 are the same, and at least two pairs are provided.

[0087] Preferably, the number of the second check blocks 342 and the second check seats 341 are both two pairs, so that the second check seats 341 are arranged opposite each other on the inner wall of the separation bin 31, and the second check blocks 342 are arranged in the corresponding second check seats 341, thereby ensuring the stability of the support for the stacked material trays 5.

[0088] Specifically, the separation bin 31 includes a front guide plate 311, a rear guide plate 312, a left plate 313 and a right plate 314. The front guide plate 311, the rear guide plate 312, the left plate 313 and the right plate 314 are combined to form a separation bin 31 with a rectangular inner cavity. The left plate 313 and the right plate 314 are both provided with sliding grooves, and the second check seat 341 can be slidably arranged in the corresponding sliding groove to realize the up and down movement of the second check block 342.

[0089] In addition, in order to facilitate the guidance of the up and down movement of the second check block 342, a second linear guide rail 35 and a third linear guide rail 36 are also included, wherein one end of the bracket 343 is slidably connected to the second linear guide rail 35, and the other end of the bracket 343 is slidably connected to the third linear guide rail 36. The second linear guide rail 35 can be arranged on the outside of the separation bin 31, and the third linear guide rail 36 can be fixed on the separation bin 31.

[0090] In some embodiments, the tray separation mechanism 3 further includes a through-beam sensor 37, which is disposed on the separation chamber 31 and is used to detect whether the stacked trays 5 have reached the separation position. When the lifting mechanism 2 lifts the stacked trays 5 to the separation position (specifically, when the top tray in the stacked trays 5 reaches the separation position), the through-beam sensor 37 detects the stacked trays 5 and issues a signal indicating that the trays have reached the separation position, thereby activating the lifting drive assembly 344.

[0091] In some embodiments, the tray separation mechanism 3 further includes a photoelectric sensor 38 , which is disposed on the top of the separation bin 31 . The photoelectric sensor 38 is used to detect whether the number of stacked trays reaches a threshold.

[0092] For example, when the number of trays on the second non-return assembly 33 reaches a threshold, the photoelectric sensor 38 generates a signal, which can cause an alarm to sound to prompt on-site staff to remove the stacked trays.

[0093] In some embodiments, the grabbing and feeding mechanism 4 includes a clamp 41, a finger cylinder 42 and a conveying assembly 43, wherein the clamp 41 is used to clamp the material tray, the finger cylinder 42 is connected to the clamp 41, the finger cylinder 42 is used to provide power so that the clamp 41 clamps the material tray, the conveying assembly 43 is connected to the finger cylinder 42, and the conveying assembly 43 is used to drive the finger cylinder 42 to move toward or away from the separation bin 31.

[0094] Specifically, the transmission component 43 can be a conveyor belt component, which includes a driving motor 431, a driving wheel 432, a driven wheel 433 and a conveyor belt 434. The finger cylinder 42 is fixedly connected to the conveyor belt 434. After the driving motor 431 is started, the finger cylinder 42 and the clamp 41 can be driven to move through the conveyor belt 434.

[0095] In some embodiments, the grabbing and feeding mechanism 4 further includes a base 44, a fourth linear guide 45, and a slider 46. The fourth linear guide 45 is disposed on the base 44, and the slider 46 is connected to the finger cylinder 42. The slider 46 is slidably disposed on the fourth linear guide 45. This arrangement allows the finger cylinder 42 to be guided when the conveyor belt 434 drives the finger cylinder 42 to move, thereby ensuring the stability of the movement of the finger cylinder 42.

[0096] In some embodiments, a positioning mechanism is further provided on the base 44, and the positioning mechanism is used to position the tray after the tray reaches the working position. The positioning mechanism may include a fixed positioning component and a movable positioning component, and the positioning of the tray is achieved by the movement of the movable positioning component relative to the fixed positioning component. For example, the movable positioning component may include a first positioning cylinder 47 and a second positioning cylinder 48, and the first positioning cylinder 47 and the second positioning cylinder 48 are positioning cylinders in the X-axis direction and the Y-axis direction respectively, for positioning the tray in the horizontal plane. Furthermore, a third positioning cylinder 49 may also be provided to achieve positioning of the tray in the vertical direction (i.e., the Z-axis direction).

[0097] In addition, in order to facilitate the fixing of the lines and the air pipe, a drag chain 410 can also be provided, and the lines and the air pipe are fixed on the drag chain 410 to prevent the on-site lines and the air pipe from affecting the operation of the grabbing and feeding mechanism 4.

[0098] In order to facilitate the detection of whether the material tray is in place, a position detector 411 can also be set up. The position detector 411 can also use a photoelectric sensor. When the material tray reaches the working position, the position detector 411 can detect the material tray and send an in-place signal, thereby facilitating the material picking mechanism to come and take away the material (chips) on the material tray.

[0099] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
