Description

Technical Field

[0001] The invention relates to the technical field of glass loading and unloading equipment, and in particular to an adsorption-type glass loading and unloading device. Background Art

[0002] An adsorption glass loading and unloading device is mainly used in automated production lines to safely and efficiently transport and place glass plates, especially in glass deep processing, building curtain wall production, home appliance manufacturing and other industries. This device mainly uses vacuum adsorption technology to grab and fix the glass plate to ensure the stability and safety of the glass during the handling process.

[0003] The existing glass loading and unloading devices usually require manual operation of the air valve to switch the negative pressure suction air source when adsorbing, capturing, lifting, loosening and unloading the glass. The operation is relatively troublesome and inconvenient. Although some devices can automatically switch the negative pressure suction air source on and off when lifting and loosening the glass, the automatic switching of the negative pressure suction air source is mostly implemented through limit sensors in conjunction with solenoid valves. The limit sensors and solenoid valves require additional wiring and connection, which are troublesome and inconvenient to install and use. In addition, the procurement costs of the limit sensors and solenoid valves are high, which is not conducive to reducing the overall manufacturing cost of the device. Summary of the invention

[0004] In view of this, the present invention provides an adsorption-type glass loading and unloading device to solve the problem of automatic switching of the negative pressure suction air source, which is mostly implemented through a limit sensor in conjunction with a solenoid valve. The installation and use are relatively troublesome and inconvenient, which is not conducive to reducing the overall manufacturing cost of the device.

[0005] The technical solution proposed by the present invention is: an adsorption-type glass loading and unloading device, specifically comprising: a frame, wherein the frame as a whole is composed of two U-shaped vertical frames symmetrically welded;

[0006] In the space between the horizontal bracing side rods at the top of the two U-shaped vertical frames, four mutually parallel swing arms are rotatably installed, and a horizontal loading rack is rotatably connected between the head ends of the four swing arms, and a horizontal bracing connecting rod is rotatably connected between the tail ends of the two swing arms on each side; two vertical air exhaust pipes are symmetrically penetrated and slid on the horizontal loading rack through the pushing of a spring, and the bottom threads of the vertical air exhaust pipes are fastened with suction cups, and the top ends of the two vertical air exhaust pipes are commonly fastened with T-shaped air distribution pipes through threads; a chain with a rectangular structure in a tensioned state is installed in the bottom side part of the space between the two U-shaped vertical frames, and an air valve is fixed on the longitudinal bracing side rod of the U-shaped vertical frame, and the air valve is connected to the T-shaped air distribution pipe through a hose, and the chain is used to drive the air valve to switch while driving the four swing arms to swing back and forth.

[0007] Furthermore, two longitudinal support positioning shafts are symmetrically welded between the top transverse support side bars of the two U-shaped vertical frames, and the four swing rods are arranged in groups of two to rotate with the two longitudinal support positioning shafts, and the two swing rods in each group of swing rods are symmetrically arranged.

[0008] Furthermore, a force transmission rod is rotatably installed between the middle sections of the two cross brace connecting rods, and a force transmission sleeve is welded to the middle position of the force transmission rod.

[0009] Furthermore, the horizontal loading rack as a whole is composed of four loading rods that are welded together, two horizontally and two vertically interlaced with each other, wherein two longitudinal loading rods protrude from the frame, and the head end portion of the longitudinal loading rod is welded with an upwardly supporting L-shaped support rod, and the vertical exhaust pipe is pushed by a spring and slides through the top horizontal portion of the L-shaped support rod and the head end of the longitudinal loading rod.

[0010] Furthermore, a horizontal support frame is welded to the lower half of the vertical support side rods of the U-shaped vertical frame. The horizontal support frames are symmetrically arranged in two U-shaped structures, and the four cross-bracing side plates of the two horizontal support frames are fixedly connected to the inner sides of the four vertical support side rods on the two U-shaped vertical frames.

[0011] Furthermore, two sprockets are symmetrically mounted on the longitudinal support side plates at the head end of the horizontal support frame, the chain is tensioned and sleeved on the four sprockets, and two vertically supported shifting shafts are symmetrically fixed to the same position on the chain.

[0012] Furthermore, a horizontal support positioning shaft is welded between the two vertical support side bars of the U-shaped vertical frame, the horizontal support positioning shaft is located above the horizontal support frame, a T-shaped driving frame is slidably mounted on the two horizontal support positioning shafts, and a strip driving frame is welded to the bottom of the vertical support bar of the T-shaped driving frame;

[0013] The vertical support rod of the T-shaped driving frame is correspondingly and slidably matched with the force transmission shaft sleeve, and the upper shifting shaft is plug-connected and matched with the strip driving frame.

[0014] Furthermore, a mounting ring is welded on a vertical support side rod of one of the U-shaped vertical frames, and the mounting ring is located in the adjacent space below the U-shaped vertical frame at the corresponding position. A driving device is threadedly fastened and hoisted on the mounting ring, and the driving device is connected to a sprocket shaft at the corresponding position for transmission.

[0015] Furthermore, the air valve is threadedly fastened to the lower half of the two vertical support side rods on the same side of the two U-shaped vertical frames, and the air valve is fixed to the outer side of the vertical support side rods of the U-shaped vertical frames;

[0016] The valve body of the gas valve is composed of three valve tubes, one long and two short, which are welded vertically and staggered. A hexagonal sliding shaft is installed in the interior of the long valve tube through which a spring pushes and slides. A valve core with a columnar structure is welded at the head end of the hexagonal sliding shaft. A sealing plate is welded and sleeved on the head end of the hexagonal sliding shaft. Under normal conditions, the sealing plate is sealed against the side wall of the head end of the long valve tube.

[0017] An L-shaped transmission rod is welded to the head end of the hexagonal sliding shaft, and a vertical force block is bent at the head end of the longitudinal support part of the L-shaped transmission rod, and the longitudinal support part of the L-shaped transmission rod is slidably fitted with the longitudinal support side plate of the horizontal support frame close to the driving device side;

[0018] The upper shifting shaft rotates with the chain and comes into contact with the vertical force bearing block.

[0019] The present invention provides an adsorption-type glass loading and unloading device, which has the following beneficial effects:

[0020] The present invention uses the power transmission of the lower pull shaft in conjunction with the spring on the hexagonal sliding shaft. When the chain rotates to drive the four swing arms to swing left and right to transfer the glass, the air valve can be driven to automatically switch on and off when the glass is loosened and unloaded and adsorbed and grabbed, and the negative pressure suction air source can be turned on and off. This can save the trouble of manually operating the air valve to switch the negative pressure suction air source each time the glass is loosened or tightened. Compared with the prior art, the operation is convenient and efficient.

[0021] In addition, the automatic switching function of the negative pressure suction air source of the present device completely relies on a purely mechanical sliding valve core structure which is arranged inside the air valve and pushed by a spring and is assisted by a chain drive. The pure mechanical sliding valve core structure is composed of an L-shaped transmission rod, a hexagonal sliding shaft, and springs on the valve core and the hexagonal sliding shaft. The above components are all traditional mechanical components with simple structure, manufacturing process and relatively low cost. Compared with the existing technology of automatically switching the negative pressure suction air source through a limit sensor and cooperating with an electromagnetic valve, there is no need for additional wiring and connection for the limit sensor and the electromagnetic valve. It is easy to install and use, and the implementation cost of the automatic function is low, which is conducive to reducing the overall cost of the device.

[0022] In addition, when the lower shift shaft slides forward, its left and right positions remain unchanged, and the four swing arms will remain in a left-leaning state for a certain period of time, and the two vertical exhaust pipes and two suction cups will remain in a state close to the first station loading plate to unload the glass. The time period when the two vertical exhaust pipes and the two suction cups are kept in position allows the lower shift shaft to drive the air valve to close, and allows the two suction cups to have sufficient time to separate and disengage from the glass.

[0023] In addition, when the glass is lifted, the distance that the two vertical vacuum tubes slide down can provide a movable margin for the two suction cups to slide up and separate from the glass. This movable margin is used together with the rebound and pushing of the springs on the two vertical vacuum tubes to ensure that the two suction cups and the glass are separated and unloaded normally and effectively, avoiding the situation where the two suction cups re-suck and grab the glass that has been separated and unloaded from them.

[0024] In addition, before unloading, the glass is attached to the first station loading plate and a gap is maintained between the glass and the first station loading plate. Firstly, it can ensure that the glass can rely on its gravity to fall and unload. Secondly, it can ensure that the first station loading plate does not slide up and push the two vertical exhaust pipes. This ensures the existence of movable margin space on the two vertical exhaust pipes, which helps to indirectly ensure the normal and effective implementation of the unloading function of the two suction cups being completely separated from the glass.

The frame 1 as a whole is composed of two U-shaped vertical frames 106 symmetrically welded;

[0054] Among them, in the space between the horizontal brace side bars at the top of the two U-shaped vertical frames 106, four mutually parallel swing rods 2 are rotatably installed, and the head ends of the four swing rods 2 are rotatably connected to the horizontal material carrier 201, and the tail ends of the two swing rods 2 on each side are rotatably connected to the horizontal material carrier 201.

Figure 1 and Figure 2 As shown); the valve body of the air valve 6 is composed of three valve tubes, one long and two short, welded vertically; the head end of the hose is connected to the head end opening of the vertical support pipe section of the T-shaped air pipe 302, and the tail end is connected to the top end opening of the upper short valve tube, and the bottom end opening of the lower short valve tube is connected to the external negative pressure suction system through a soft air pipe. When the air valve 6 is opened, the negative pressure suction system is connected to the two suction cups 301, and suction can be generated inside the suction cups 301 to form a negative pressure suction force, so that the two suction cups 301 can absorb and grab the glass; the first station loading plate 7 and the second station loading plate 8 are arranged in a left-right symmetrical manner in the adjacent space in front of the top of the frame 1;

[0055] The four swing rods 2, the horizontal material carrier 201 and the two horizontal connecting rods 203 are connected together to form a parallelogram swing mechanism. Through this mechanism, the four swing rods 2 can swing left and right to drive the two vertical suction pipes 3, the two suction cups 301 and the glass adsorbed and grasped on the two suction cups 301 to transfer between the first station material carrier 7 and the second station material carrier 8 (combined with Figure 1 , Figure 4 and Figure 7 ) to load and unload the glass.

[0056] Preferably, two longitudinal support positioning shafts 103 are symmetrically welded between the top horizontal support side bars of the two U-shaped vertical frames 106, and the four swing rods 2 are arranged in groups of two to rotate with the two longitudinal support positioning shafts 103, and the two swing rods 2 in each group of swing rods 2 are symmetrically arranged.

[0057] Preferably, a force transmission rod 204 is rotatably mounted between the middle sections of the two cross-bracing connecting rods 203 , and a force transmission sleeve is welded at the middle position of the force transmission rod 204 .

[0058] Preferably, the horizontal loading rack 201 is composed of four loading rods that are welded together, two horizontally and two vertically interlaced with each other, wherein two longitudinal loading rods protrude from the frame 1, and the head end portion of the longitudinal loading rod is welded with an upwardly supporting L-shaped support rod 202, and the vertical exhaust pipe 3 is pushed by a spring and slides through the top horizontal portion of the L-shaped support rod 202 and the head end of the longitudinal loading rod.

[0060] Preferably, two sprockets 105 are symmetrically mounted on the longitudinal support side plates at the head end of the horizontal support frame 101, the chain 5 is tensioned and sleeved on the four sprockets 105, and two vertically supported shifting shafts 501 (such as Figure 6 shown).

[0061] Preferably, a transverse support positioning shaft 102 is welded between the two vertical support side rods of the U-shaped vertical frame 106, and the transverse support positioning shaft 102 is located above the horizontal support frame 101. A T-shaped drive frame 9 is slidably installed on the two transverse support positioning shafts 102, and a strip drive frame 901 is welded to the bottom of the longitudinal support rods of the T-shaped drive frame 9; the vertical support rods of the T-shaped drive frame 9 correspond to the force transmission sleeves that penetrate and slide, and the upper shift shaft 501 is plug-fitted with the strip drive frame 901, and through the power transmission of the force transmission sleeve, the force transmission rod 204 and the two transverse support connecting rods 203, the T-shaped drive frame 9 can slide left and right to drive and control the four swing arms 2 to swing left and right, and through the power transmission of the upper shift shaft 501, the chain 5 can rotate to drive the strip drive frame 901 and the T-shaped drive frame 9 to slide left and right.

[0062] Preferably, a mounting ring 104 is welded on a vertical support side rod of a U-shaped vertical frame 106, and the mounting ring 104 is located in the adjacent space below the U-shaped vertical frame 106 at the corresponding position. A driving device 4 is threadedly fastened and hoisted on the mounting ring 104, and the driving device 4 is axially connected to a sprocket 105 at the corresponding position for transmission. Through the four sprockets 105, the driving device 4 can drive the chain 5 to rotate, thereby providing driving force for transferring and loading and unloading the glass.

[0063] Preferably, a hexagonal sliding shaft 601 is installed in the interior of the long valve tube through a spring push-through sliding installation, a valve core 603 of a columnar structure is welded to the head end of the hexagonal sliding shaft 601, and a sealing plate 604 is welded to the head end of the hexagonal sliding shaft 601. Under normal conditions, the sealing plate 604 is sealed against the side wall of the head end of the long valve tube; an L-shaped transmission rod 602 is welded to the head end of the hexagonal sliding shaft 601, and a vertical force block is bent at the head end of the longitudinal support part of the L-shaped transmission rod 602, and the longitudinal support part of the L-shaped transmission rod 602 is slidably fitted with the longitudinal support side plate of the horizontal support frame 101 close to the side of the driving device 4; the upper side shifting shaft 501 rotates with the chain 5 and is in contact with the vertical force block;

[0064] During the whole process of adsorption, grasping and transfer of the glass, the air valve 6 is kept open to ensure that the two suction cups 301 can stably grasp and fix the glass to prevent the glass from falling. When the upper side shift shaft 501 follows the chain 5 to move to the leftmost position, the T-shaped driving frame 9 is driven to the top of the two chains 5 on the left, and the four swing arms 2 are in a right-leaning state. The two suction cups 301 are transferred to press on the second station loading plate 8 to adsorb and grasp the glass (refer to Figure 1 , Figure 2 and Figure 3 ), when the upper side shift shaft 501 follows the chain 5 to move to the rightmost position, the T-shaped driving frame 9 is driven to the top of the two right chains 5, the swing rods 2 are in a left-leaning state, and the two suction cups 301 are transferred to the first station loading plate 7 to loosen and unload the glass sucked and grasped thereon (refer to Figure 7 , Figure 8and Fig. 9 ), and when the upper shift shaft 501 follows the chain 5 to move to the leftmost position, the lower shift shaft 501 is also synchronously moved to the leftmost position. At this time, following the continuous rotation of the chain 5, the movement direction of the lower shift shaft 501 changes, and it begins to slide forward and abuts against the vertical force block. The abutment and contact between the lower shift shaft 501 and the vertical force block can push and drive the L-shaped transmission rod 602, the hexagonal sliding shaft 601 and the valve core 603 to slide forward, blocking the through air holes between the two short valve tubes and the long valve tube, automatically closing the air valve 6 to cut off the negative pressure suction air source, releasing the negative pressure suction force of the two suction cups 301, so that the suction cups 301 release the glass, and completing When the glass is unloaded on the first station loading plate 7, the lower side shift shaft 501 slides to the frontmost position on the right, and its movement direction changes again and starts to slide to the left. At this time, the lower side shift shaft 501 is separated from the vertical force block. After the lower side shift shaft 501 is separated from the vertical force block, the L-shaped transmission rod 602, the hexagonal sliding shaft 601 and the valve core 603 lose the forward pushing holding force from the lower side shift shaft 501, and can be automatically rebounded by the spring on the hexagonal sliding shaft 601 and driven back to the original position, so that the air valve 6 is automatically opened to restore the supply of the negative pressure suction air source, and the negative pressure suction force of the two suction cups 301 is restored, so that the two suction cups 301 can adsorb and grab the glass again (refer to Figure 7 , Figure 8 , Fig. 9 and Fig.11 );

[0065] Then, through the power transmission of the lower pull shaft 501 and the use of the spring on the hexagonal sliding shaft 601, the chain 5 drives the swing rods 2 to swing left and right to transfer the glass. When the glass is loosened and unloaded or adsorbed and grabbed, it can also drive the air valve 6 to automatically switch on and off, and the negative pressure suction air source is turned on and off, which can save the trouble of manually operating the air valve 6 to switch the negative pressure suction air source every time the glass is loosened or tightened. Compared with the prior art, the operation is convenient and efficient, and the automatic switching function of the negative pressure suction air source of the device is completely dependent on the spring arranged inside the air valve 6. The pure mechanical sliding valve core structure is pushed by a spring and driven by a chain 5. The pure mechanical sliding valve core structure is composed of an L-shaped transmission rod 602, a hexagonal sliding shaft 601, a valve core 603 and a spring on the hexagonal sliding shaft 601. The above components are all traditional mechanical components with simple structure, manufacturing process and relatively low cost. Compared with the existing technology of automatically switching the negative pressure suction air source through a limit sensor and a solenoid valve, there is no need for additional wiring and connection for the limit sensor and the solenoid valve. It is easy to install and use, and the implementation cost of the automation function is low, which is conducive to reducing the overall cost of the device.

[0066] It is worth noting that when the lower side shift shaft 501 slides forward, its left and right positions remain unchanged, and the four swing arms 2 are kept in a left-leaning state for a certain period of time, and the two vertical exhaust pipes 3 and the two suction cups 301 are kept in a state close to the first station loading plate 7 for unloading the glass. The time period during which the two vertical exhaust pipes 3 and the two suction cups 301 are kept in position is sufficient for the lower side shift shaft 501 to drive the air valve 6 to close, and the two suction cups 301 have sufficient time to separate from the glass.

[0067] The suction cup 301 has a certain height. When it is compressed and adsorbed on the glass, the height is greatly reduced. This means that when it is separated from the glass, the distance between it and the glass must be greater than its height before being compressed, so as to avoid that the suction cup 301 cannot be completely separated from the glass, and when the air valve 6 is opened again, the glass that has been separated from it for unloading is sucked and grabbed again, affecting the normal unloading of the glass;

[0068] The two vertical exhaust pipes 3 are installed by spring push sliding. When the glass is lifted and transferred, the heavy pressure of the glass drives the two vertical exhaust pipes 3 to compress the two springs thereon and slide downward (refer to Figure 1 and Figure 5 ), and when the swing rods 2 swing to the left, the two vertical exhaust pipes 3 are transferred to the first station loading plate 7, and the glass is ready to be loosened and unloaded, the glass is close to the first station loading plate 7 but not directly in contact with the first station loading plate 7. The glass still presses the two vertical exhaust pipes 3 to keep them in a downward state (refer to Figure 7 ), during this process, when the air valve 6 is closed, the two suction cups 301 lose their adsorption and holding force on the glass, and the glass can rely on its gravity to slide down relative to the two suction cups 301 and abut against the first station loading plate 7. After the two suction cups 301 lose their adsorption and holding force, the connection between them and the glass becomes loose. At this time, the springs on the two vertical suction pipes 3 can rebound and push to drive their bodies and the two suction cups 301 to slide upward and reset to completely separate from the glass. Then, when the glass is lifted, the distance that the two vertical suction pipes 3 slide down can provide a movable margin for the upward sliding separation of the two suction cups 301 and the glass. This movable margin is used together with the rebound and pushing of the springs on the two vertical suction pipes 3 to ensure that the two suction cups 301 and the glass are separated and unloaded normally and effectively, and avoid the situation where the two suction cups 301 again suck and grab the glass that has been separated and unloaded from them;

[0069] Before unloading, the glass is attached to the first station loading plate 7 and a gap is maintained between the glass and the first station loading plate 7. Firstly, it can ensure that the glass can fall down by its gravity for unloading. Secondly, it can ensure that the first station loading plate 7 does not slide up and push the two vertical exhaust pipes 3, thereby ensuring the existence of movable margin space on the two vertical exhaust pipes 3, which helps to indirectly ensure the normal and effective implementation of the unloading function of the two suction cups 301 being completely separated from the glass.

[0070] Working principle: The first station loading plate 7 and the second station loading plate 8 are arranged symmetrically in the adjacent space in front of the top of the frame 1. When the air valve 6 is opened, the negative pressure suction system is connected with the two suction cups 301, and suction can be generated inside the suction cups 301 to form a negative pressure suction force, so that the two suction cups 301 can absorb and grab the glass; the first station loading plate 7 and the second station loading plate 8 are arranged symmetrically in the adjacent space in front of the top of the frame 1;

[0071] The four swing arms 2, the horizontal material carrier 201 and the two horizontal bracing connecting rods 203 are connected together to form a parallelogram swing mechanism. Through this mechanism, the four swing arms 2 can swing left and right to drive the two vertical exhaust pipes 3, the two suction cups 301 and the glass adsorbed and grasped on the two suction cups 301 to transfer between the first station material carrier plate 7 and the second station material carrier plate 8, so as to load and unload the glass. Through the power transmission of the force transmission sleeve, the force transmission rod 204 and the two horizontal bracing connecting rods 203, the T-shaped driving frame 9 can slide left and right to drive and control the four swing arms 2 to swing left and right, and through the power transmission of the upper side shifting shaft 501, the chain 5 can rotate to drive the strip driving frame 901 and the T-shaped driving frame 9 to slide left and right. Through the four sprockets 105, the driving device 4 can drive the chain 5 to rotate, so as to provide driving force for transferring and loading the glass.

[0072] During the whole process of adsorption, grasping and transfer of the glass, the air valve 6 is kept open to ensure that the two suction cups 301 can stably grasp and fix the glass to prevent the glass from falling. When the upper side shift shaft 501 follows the chain 5 to move to the leftmost position, the T-shaped driving frame 9 is driven to the top of the two chains 5 on the left, and the four swing arms 2 are in a right-leaning state. The two suction cups 301 are transferred to press on the second station loading plate 8 to adsorb and grasp the glass (refer to Figure 1 , Figure 2 and Figure 3 ), when the upper side shift shaft 501 follows the chain 5 to move to the rightmost position, the T-shaped driving frame 9 is driven to the top of the two right chains 5, the swing rods 2 are in a left-leaning state, and the two suction cups 301 are transferred to the first station loading plate 7 to loosen and unload the glass sucked and grasped thereon (refer to Figure 7 , Figure 8 and Fig. 9), and when the upper shift shaft 501 follows the chain 5 to move to the leftmost position, the lower shift shaft 501 is also synchronously moved to the leftmost position. At this time, following the continuous rotation of the chain 5, the movement direction of the lower shift shaft 501 changes, and it begins to slide forward and abuts against the vertical force block. The abutment and contact between the lower shift shaft 501 and the vertical force block can push and drive the L-shaped transmission rod 602, the hexagonal sliding shaft 601 and the valve core 603 to slide forward, blocking the through air holes between the two short valve tubes and the long valve tube, automatically closing the air valve 6 to cut off the negative pressure suction air source, releasing the negative pressure suction force of the two suction cups 301, so that the suction cups 301 release the glass, and completing When the glass is unloaded on the first station loading plate 7, the lower side shift shaft 501 slides to the frontmost position on the right, and its movement direction changes again and starts to slide to the left. At this time, the lower side shift shaft 501 is separated from the vertical force block. After the lower side shift shaft 501 is separated from the vertical force block, the L-shaped transmission rod 602, the hexagonal sliding shaft 601 and the valve core 603 lose the forward pushing holding force from the lower side shift shaft 501, and can be automatically rebounded by the spring on the hexagonal sliding shaft 601 and driven back to the original position, so that the air valve 6 is automatically opened to restore the supply of the negative pressure suction air source, and the negative pressure suction force of the two suction cups 301 is restored, so that the two suction cups 301 can adsorb and grab the glass again (refer to Figure 7 , Figure 8 , Fig. 9 and Fig.11 ).
