Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] To solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0024] As Figures 1 to 3 shown, an automatic palletizing device disclosed in an embodiment of the present utility model includes a transfer track 1 and a lifting mechanism 2. The transfer track 1 is provided on both sides of the lifting mechanism 2. The conveying directions of the transfer tracks 1 on both sides are the same. A fixing member 3 is provided on the outer side of the transfer track 1. A supporting member 4 is installed on the fixing member 3. The horizontal heights of the supporting members 4 on the fixing members 3 on both sides are the same. During the process of the lifting mechanism 2 driving the workpiece to rise, the supporting member 4 rotates and approaches the fixing member 3; after the lifting mechanism 2 drives the workpiece to pass through the supporting member 4, the supporting member 4 rotates away from the fixing member 3 to a horizontal state and is fixed.

[0025] Among them, the lifting mechanism 2 drives the workpiece to move linearly. When the transfer track 1 conveys the workpiece to the specified position, the lifting mechanism 2 drives the workpiece to rise. Transfer tracks 1 are respectively arranged on both sides of the lifting mechanism 2, and the conveying directions of the transfer tracks 1 on both sides are the same. In this way, the PCB board workpieces are conveyed by the transfer tracks 1 on both sides. Fixing members 3 are arranged on the outer sides of the transfer tracks 1, that is, it indicates that fixing members 3 are respectively arranged on the transfer tracks 1 on both sides. A fixing space for stacking and placing PCB board workpieces is formed between the fixing members 3 on both sides. Further, supporting members 4 are designed on the fixing members 3, so there are supporting members 4 on both sides, and the horizontal heights of the supporting members 4 on both sides are the same. Then, a horizontal plane for fixing the workpiece is formed between the supporting members 4 on both sides.

[0026] During the process of the lifting mechanism 2 driving the PCB board workpiece to rise, the supporting member 4 can rotate close to the fixing member 3. Obviously, the supporting member 4 is arranged inside the fixing member 3. Specifically, when the workpiece moves upward, the workpiece causes the supporting member 4 to rotate and close to the inner side of the fixing member 3. During the jacking process of the workpiece, the supporting space formed between the supporting members 4 on both sides gradually increases. When the lifting mechanism 2 drives the workpiece to continue rising and passes over the supporting member 4, the supporting member 4 begins to rotate away from the fixing member 3 to the horizontal state and is fixed. That is, after the workpiece passes over the upper end of the supporting member 4, the supporting member 4 naturally rotates and falls back to the horizontal state and remains fixed. At this time, when the lifting mechanism 2 descends, the workpiece moves downward accordingly, and the lower surfaces on both sides of the workpiece are in contact with the supporting member 4, that is, the supporting member 4 fixes the workpiece on the horizontal plane where the supporting member 4 is located. Each PCB board is fixed on the supporting members 4 on both sides in a cycle.

[0027] It should be noted that the initial position of the supporting member 4 is the horizontal state. At this time, the supporting plane of the supporting member 4 is parallel to the plane of the transfer track 1, and the supporting member 4 is located above the transfer track 1. Also, the rotational damping of the supporting member 4 is small. When the workpiece moves upward under the jacking action of the lifting mechanism 2 and the two sides of the workpiece are in contact with the supporting member 4 and jack it up, the supporting member 4 can rotate easily. The supporting members 4 on both sides rotate close to the fixing member 3, and the situation where the supporting member 4 jams the workpiece will not occur. And after the jacking height of the workpiece exceeds the supporting member 4, the supporting member 4 can freely rotate back to the initial position. In this way, after the lifting mechanism 2 drives the workpiece to move upward and cross the supporting member 4, the lifting mechanism 2 drives the workpiece to move downward, and the workpiece is stuck by the supporting member 4 and will not continue to move downward, thereby completing the stacking and fixing of the workpiece.

[0028] In addition, the width between the two transfer tracks 1 on both sides is adjusted according to the width of the workpiece. Further, the width between the two fixing members 3 or the two supporting members 4 on both sides can also be adjusted according to the width of the workpiece. In the width direction, one side of the workpiece is exactly flush with one side of the transfer track 1. At this time, the end of the supporting member 4 away from the fixing member 3 at the initial position extends to the inner side of the horizontal transfer track 1. It is only necessary to ensure that when the supporting member 4 rotates close to the fixing member 3, the workpiece can move upward between the two supporting members 4 that are folded up from both sides, and at the same time, when the supporting member 4 rotates back to the initial position, it can fix the workpiece that has moved downward so that the workpiece does not continue to move downward.

[0029] Similarly, in the width direction, one side of the workpiece can also exceed one side of the transfer track 1. At this time, the horizontal installation position of the supporting member 4 is moved out a certain distance along the outside of the transfer track 1. It is only necessary to ensure that when the supporting member 4 rotates close to the fixing member 3, it does not hinder the upward movement of the workpiece, and at the same time, after the supporting member 4 freely falls back to the initial position, it can fix both sides of the workpiece. In addition, the width between the two fixing members 3 on both sides can be equal to the width of the workpiece, or the width of the two fixing members 3 on both sides can be slightly larger than the width of the workpiece to limit and fix both sides of the workpiece.

[0030] After the high-temperature adhesive tape is pasted on the PCB board by the automatic adhesive tape mounting equipment, the automatic palletizing device of this embodiment directly completes the automatic collection, sorting and palletizing of the PCB boards, so as to ensure that the direction of each PCB board is consistent, which is convenient for the automated production of the next process of the PCB board, reduces the labor intensity of employees, and also solves the problems of detachment and warping of the pasted high-temperature adhesive tape in manual sorting of PCB boards.

[0031] In some embodiments, one fixing member 3 is erected at one transfer track 1, and the other fixing member 3 is erected at the other transfer track 1. The two fixing members 3 on both sides are arranged oppositely, and the height of the fixing member 3 is adjusted according to the specific type of the PCB board. The fixing member 3 can be installed above the outside of the transfer track 1, or can be installed behind the outside of one transfer track 1 away from the other transfer track 1.

[0032] In a specific example, at least two supporting members 5 are arranged along the conveying direction of the transfer track 1 on the fixing member 3, and the at least two supporting members 5 are arranged at intervals.

[0033] In some embodiments, limit rods 5 are provided at the rear ends of the two transfer tracks 1 on both sides, and the two limit rods 5 on both sides are symmetrically arranged. After the workpiece is transferred to the designated position, the limit rod 5 is used to limit the further conveyance of the workpiece to the rear end of the transfer track 1. At the same time, the symmetrically installed limit rods 5 can ensure the consistency of the stacking of the workpieces.

[0034] The limiting rod 5 can be installed on the fixing member 3 or independently installed at the rear end position of the transmission track 1, as long as it is ensured that the limiting rod 5 can prevent the workpiece from being further conveyed and at the same time ensure that the end of the workpiece in contact with the limiting rod 5 remains horizontal.

[0035] In some embodiments, a limiting opening 31 is formed in the fixing member 3, and the supporting member 4 is rotatably installed in the limiting opening 31. When the supporting member 4 is in a horizontal state, the supporting member 4 abuts against the limiting opening 31.

[0036] By providing the limiting opening 31 on the fixing member 3 and rotatably installing the supporting member 4 in the limiting opening 31, when the supporting member 4 is in a horizontal state, since the supporting member 4 abuts against the limiting opening 31, at this time, the supporting member 4 can be in a horizontal state and remain fixed. That is, when the support frame abuts against the limiting opening 31, the horizontal state of the supporting member 4 is not damaged without external force, and the supporting member 4 is arranged parallel to the transmission plane of the transmission track 1. When the workpiece moves upward to lift the supporting member 4, the horizontal state of the supporting member 4 is damaged, and the supporting member 4 rotates close to the fixing member 3, and the supporting space formed by the two supporting members 4 increases, and the workpiece smoothly moves above the supporting member 4.

[0037] Further, a limiting portion is provided at the upper end of the fixing member 3 at the limiting opening 31, and the limiting portion is used to prevent the supporting member 4 from rotating excessively, and the limiting portion can be provided in a protruding manner.

[0038] In a specific example, the supporting member 4 is provided with a hinge portion 41 and a supporting portion 42. The hinge portion 41 is connected to the supporting portion 42. A rotating shaft 32 is provided in the limiting opening 31, and the hinge portion 41 is hinge-connected to the rotating shaft 32. In the horizontal state, the side of the supporting member 4 close to the hinge portion 41 abuts against the limiting opening 31, or the connection portion between the supporting portion 42 and the hinge portion 41 can be made to abut against the limiting opening 31, and the limiting opening 31 ensures that the supporting portion 42 remains fixed in a horizontal state.

[0039] Furthermore, the opening area of the limiting opening 31 is smaller than the area of the supporting portion 42. Specifically, along the conveying direction of the transmission track 1, the opening width of the limiting opening 31 is smaller than the width of the supporting portion 42, that is, the hinge portion 41 of the supporting member 4 can rotate freely in the limiting opening 31. When the supporting portion 42 rotates close to the fixing member 3, it is blocked by the front end or the rear end of the limiting opening 31 from approaching the fixing member 3 further. Similarly, along the longitudinal direction of the transmission track 1, the opening height of the limiting opening 31 is smaller than the height of the supporting portion 42. When the supporting portion 42 rotates close to the fixing member 3, it is blocked by the upper end of the limiting opening 31 from approaching the fixing member 3 further.

[0040] Further, the hinge connection between the hinge portion 41 of the support member 4 and the rotating shaft 32 is similar to a hinge connection of a hinge. After the workpiece passes through the upper end of the support member 4, it can freely rotate back to the initial position. Also, during the downward movement of the workpiece above, when the workpiece abuts against and presses down on the support portion 42, the support member 4 rotates away from the fixing member 3 until it remains stationary in the horizontal rotation. The rotational damping is small, and it can only achieve one-way rotation. Specifically, the support member 4 can only achieve a maximum rotation angle of 90°. Thus, the support member 4 has the characteristic of one-way opening and closing, rotating from the horizontal state at the initial position, approaching the fixing member 3, and then rotating from the position close to the fixing member 3 back to the horizontal state.

[0041] In some embodiments, induction switches are provided at both the front end and the rear end of the transmission track 1, and the induction switches are connected to the controller.

[0042] In a specific example, the transmission track 1 uses belt transmission.

[0043] In practical applications, the transmission track 1 is docked with the blanking track of the automatic adhesive tape mounting device. After the PCB board is processed by the automatic adhesive tape mounting device, it is directly transferred from the blanking track to the transmission track 1, and the stacking is completed by the cooperation of the lifting mechanism 2, the fixing member 3, and the support member 4. Preferably, an optoelectronic induction switch is used to complete the incoming material induction and in-place induction of the PCB board on the transmission track 1.

[0044] When the induction switch installed at the lower position below the inlet of the transmission track 1 detects the PCB board, it sends an induction signal to the controller. The controller starts the belt on the transmission track 1 to convey the PCB board to the set sorting and stacking area between the two fixing members 3. At this time, the limiting rod 5 blocks the PCB board, and the belt still runs and rotates. The PCB board is blocked by the blocking rod and cannot move forward. However, when the PCB board reaches the limiting rod 5, the optoelectronic induction switch at the rear end of the transmission track 1 senses the PCB board, and the controller controls the belt to stop running, and then controls the lifting mechanism 2 to act to complete the sorting and stacking.

[0045] In some embodiments, the lifting mechanism 2 is provided with a first driving member 21 and a fixing plate 22. The first driving member 21 is connected to the fixing plate 22, and the first driving member 21 drives the fixing member 3 to perform a linear motion.

[0046] Preferably, the first driving member 21 uses a cylinder, and the telescopic movement of the piston rod of the cylinder is used to realize the lifting movement of the material and the reset of the piston rod to the original position.

[0047] More preferably, the first driving member 21 can also use a motor.

[0048] After the PCB board reaches the sorting and stacking area of ​​the transmission track 1, the output end of the first driving member 21 installed between the transmission tracks 1 on both sides drives the fixing plate 22 to rise, and lifts the PCB board as a whole from the transmission track 1. After the PCB board is lifted up to pass through the support members 4 on both sides, the output end of the first driving member 21 drops to the original position, and utilizes the one-way opening and closing characteristics of the support member 4 and the free fall back to the horizontal state. When the output end of the first driving member 21 drops, the PCB board is stuck on the upper side of the support member 4 and will not drop with the output end of the first driving member 21, completing the entire stacking action of the PCB board.

[0049] Preferably, the size of the fixing plate 22 is specifically adjusted according to different models and types of PCB boards to ensure that the fixing plate 22 has as much contact area with the plane of the PCB board as possible, and to ensure that when a part of the PCB boards are stacked above the transmission track 1 and between the fixing parts 3 on both sides, the new PCB board below is not squeezed and damaged by the gravity of the upper PCB board during the process of being lifted upward by the lifting mechanism 2.

[0050] Generally, when the weight and number of layers of the upper PCB board reach the set value, the stacked PCB boards on top can be removed and re-selected for a new round of stacking to avoid situations where the lower PCB board is damaged due to the higher the stacking and the heavier the weight. In practice, the specific design is based on the weight, load-bearing capacity, size, and model of the PCB board.

[0051] In some embodiments, an adjustment mechanism 6 is also included, which includes a second driving member and a transmission member 61. The second driving member is connected to the transmission member 61, and the transmission member 61 is connected to the transmission track 1. The second driving member drives the transmission track 1 on one side to approach or move away from the transmission track 1 on the other side through the transmission member 61.

[0052] The transmission track 1 on one side is arranged at intervals from the transmission track 1 on the other side. An adjustment mechanism 6 is added to adjust the spacing between the transmission tracks 1 on both sides to adapt to the transmission of PCB boards of different sizes. In conjunction with the lifting mechanism 2, the fixing part 3 and the supporting part 4, the collection, sorting and stacking of PCB boards of different models and types can be achieved.

[0053] Preferably, the second driving member is a motor and the transmission member 61 is a screw, which is passed through a mounting seat 7 at the lower end of the transmission track 1. The mounting seat 7 serves as a structural member that supports the transmission track 1. The motor drives the screw to rotate, so that the transmission track 1 on one side moves away from or closer to the transmission track 1 on the other side, thereby increasing or decreasing the distance between the transmission tracks 1 on both sides.

[0054] More preferably, the second driving member can also be a cylinder. The piston rod of the cylinder is connected to the transmission member 61, and the transmission member 61 is connected to the fixed seat of the transmission track 1 on one side. The transmission member 61 is driven to move by the piston rod of the cylinder, so as to move the transmission track 1 on one side closer to or away from the transmission track 1 on the other side.

[0055] It further includes a frame 8, and a mounting seat 7 is provided on the frame 8. The transmission track 1 is assembled on the mounting seat 7. A carrying platform 10 is further provided on one side of the frame 8. When the lifting mechanism 2, the fixing member 3, the supporting member 4 and the transmission track 1 cooperate to stack the PCB boards to a certain number of layers, the stacked PCB boards are manually transplanted onto the carrying platform 10 for placement.

[0056] In a specific example, a guide rail 9 is further installed on the frame 8, a slider is installed at the lower end of the mounting seat 7, and the slider is slidably connected to the guide rail 9. The length direction of the guide rail 9 is the same as the width direction of the transmission tracks 1 on both sides, that is, the length direction of the guide rail 9 is the same as the moving direction of the output end of the second driving member. When the second driving member drives the transmission track 1 on one side to move linearly through the transmission member 61, the guide rail 9 and the slider are used to ensure the stability of the overall movement of the transmission track 1, the fixing member 3 and the supporting member 4.

[0057] Preferably, at least two guide rails 9 are arranged along the length direction of the transmission track 1.

[0058] In summary, after reading the documents of the present invention, those of ordinary skill in the art can make various other corresponding transformation schemes without creative mental labor according to the technical solutions and technical concepts of the present invention, and all of them fall within the scope protected by the present invention.
