Description

Technical Field

[0001] The invention relates to the technical field of mechanical lubrication, and more particularly to an automatic bolt lubrication coating device. Background Art

[0002] In the assembly of wind turbines, bolts are the main connection method. In order to reduce the friction coefficient, reduce wear and tear, and increase equipment stability, lubricating grease is usually applied to the surface of the bolts before assembly.

[0003] At present, bolts are mainly coated manually, with one hand holding the bolt and the other hand coating it. It should be noted that the bolt consists of two parts: the head and the screw (a cylinder with external threads). Bolt coating is generally only applied to the head and tail ends of the screw.

[0004] However, with the development of large-scale wind turbines, the size of the units has increased, and the number of high-strength bolts that play an important role in connection has not only increased, but also their length has generally increased.

[0080] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0081] The core of the present invention is to provide an automatic bolt lubrication and coating device, which not only reduces the manual labor intensity, but also greatly improves the coating efficiency.

[0082] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application. In addition, the front-to-back direction described herein refers to the direction from front to back along the length of the production cabinet, that is, the direction in which the bolts are conveyed on the production line.

[0083] Please refer to Figure 1 and Figure 2 The present invention provides an automatic bolt lubrication coating device, including a feeding device 1, a feeding device 3, an input material picking device 2, a head gluing device 4, a tail gluing device 5, a receiving device 8 and a discharging material picking device.

[0084] The feeding device 1 is used to convey the bolts to the grabbing station.

[0085] The feeding device 3 includes a bolt moving frame 32 and two opposite side plates 31. The top of each side plate 31 is provided with a plurality of bolt slots 310 arranged along the front-to-back direction, and the bolt slots 310 on the two side plates 31 correspond to each other. The two opposite bolt slots 310 are used to jointly support the bolts and both the head and tail of the screw rod of the bolt extend out of the bolt slots 310. The bolt moving frame 32 can be raised and lowered and moved forward and backward and is arranged between the two side plates 31, and is used to drive multiple bolts to move at the same time, and place each bolt one by one on multiple pairs of bolt slots 310 from front to back.

[0086] The material feeding and picking device 2 is used to grab the bolts on the grabbing station to a pair of front-end bolt slots 310 .

[0087] The head glue coating device 4 is movably arranged beside the screw head located on a middle bolt slot 310, and is used to apply grease to the screw head.

[0088] The tail glue coating device 5 can be movably arranged beside the tail of the screw on the other middle bolt slot 310, and is used to apply grease to the tail of the screw.

[0089] The collecting device 8 is used to collect the bolts.

[0090] The material discharging and picking device is used to grab the bolts on a pair of rearmost bolt slots 310 and put them into the material receiving device 8 .

[0091] In the above embodiment, the function of the feeding device 1 is to convey all the bolts to be coated with glue to the grabbing station one by one. Its specific structure is not unique in this embodiment and is not specifically limited, but a belt conveyor commonly used in the prior art can be used. The function of the feeding picking device 2 is to grab the bolts on the grabbing station to the front end bolt slot 310 of the two side plates 31. Its specific structure is not unique in this embodiment and is not specifically limited, but a manipulator that can move flexibly in space in the prior art can be used. The function of the discharging picking device is to grab the bolts on the rear end bolt slot 310 of the two side plates 31 to the receiving device 8. Its specific structure can also use a manipulator that can move flexibly in space.

[0092] In the above embodiments, please refer to Figure 2 and Fig.10 The two side panels 31 are arranged opposite to each other, even if there is a gap between the two side panels 31. Each side panel 31 is provided with a plurality of bolt slots 310 arranged along the front-to-back direction. The bolt slots 310 are open slots for placing bolts, and all the bolt slots 310 on one side panel 31 correspond to all the bolt slots 310 on the other side panel 31 opposite thereto, so that the two opposite bolt slots 310 support the bolts together. It should be noted that the head of the bolt needs to extend out of the bolt slot 310 of one side panel 31, and the tail of the bolt needs to extend out of the bolt slot 310 of the other side panel 31, so as to facilitate the gluing of the head and tail of the bolt.

[0093] Preferably, the plurality of bolt slots 310 are arranged at equal intervals, thereby unifying the forward or backward movement distance of the bolt moving frame 32 each time, so as to more accurately and conveniently regulate the forward and backward movement of the bolt moving frame 32.

[0094] In the above embodiments, please refer to Fig.10The bolt moving frame 32 can be raised and lowered and moved forward and backward and is placed in the gap between the two side plates 31. Its specific structure is not unique in this embodiment and is not specifically limited, but a moving member with lifting and horizontal movement functions in the prior art can be used. Preferably, the top of the bolt moving frame 32 is provided with a plurality of clamping parts arranged along the front-to-back direction, and the clamping parts are used to clamp the screw rods of the bolts. The number of the plurality of clamping parts is greater than or equal to the number of the bolt slots 310 of each side plate 31, and the spacing between two adjacent clamping parts is consistent with the spacing between adjacent bolt slots 310 of each side plate 31, which is conducive to the bolt moving frame 32 to stably transport multiple bolts at the same time.

[0095] Therefore, when the above-mentioned automatic bolt lubrication and coating equipment is in use, the feeding device 1 first transports the bolts to be coated with grease to the grabbing station, and the feeding and picking device 2 grabs the bolts on the grabbing station to a pair of front-end bolt slots 310 (that is, the front-end bolt slots 310 of the two side plates 31), and then the bolt moving frame 32 rises to lift the bolts and drive the bolts to move backward for a certain distance, and then descends to place the bolts on the next pair of bolt slots 310, and then the feeding and picking device 2 continues to grab the next bolt and place it on a pair of front-end bolt slots 310, the bolt moving frame 32 rises again to drive the two bolts to move backward for a certain distance, and then descends to place both bolts. To the next pair of bolt slots 310, the above steps are repeated in this way to realize the conveying of multiple bolts, and in this process, if the bolt is placed on a pair of middle bolt slots 310, the head gluing device 4 will apply grease to the screw head of the bolt, and at the same time, the tail gluing device 5 will apply grease to the screw tail of the bolt, and the bolts that have been coated are placed one by one on each subsequent pair of bolt slots 310 under the drive of the bolt moving frame 32 until they are placed on a pair of rearmost bolt slots 310 (i.e., the rearmost bolt slots 310 on the two side plates 31), and the discharging picking device grabs the bolts on a pair of rearmost bolt slots 310 and puts them into the receiving device 8 for manual removal.

[0096] In summary, the present invention utilizes the head gluing device 4 and the tail gluing device 5 to simultaneously apply grease to the head and the tail of the screw respectively, so as to realize automatic gluing, and the feeding device 1, the feeding pick-up device 2, the feeding device 3 and the discharging pick-up device cooperate with each other to continuously and uninterruptedly apply glue to the bolts. Therefore, the automatic bolt lubrication and application equipment provided by the present invention can continuously and automatically apply glue, thereby reducing the labor intensity of manual labor and greatly improving the application efficiency.

[0097] In order to realize remote automated control of automatic bolt lubrication and coating equipment, on the basis of the above embodiment, it also includes a control system, and the loading device 1, the feeding device 3, the input picking device 2, the head gluing device 4, the tail gluing device 5, and the output picking device are all connected to the control system by electrical signals.

[0098] To facilitate the movement and assembly of the automatic bolt lubrication and coating equipment, please refer to the above embodiments. Figure 1 The present invention also includes a loading movable frame 10, a mobile production cabinet 9 and a discharging movable frame 13, and the four corners of the bottom ends of the three are provided with universal wheels 15 and foot cups 14, and the universal wheels 15 can be moved up and down.

[0099] Among them, the loading device 1 is arranged on the loading mobile frame 10, the conveying device, the feeding picking device 2, the head gluing device 4, the tail gluing device 5, the discharging picking device and the bolt rotation device 6 are all arranged on the mobile production cabinet 9, and the discharging picking device is arranged on the discharging mobile frame 13.

[0100] It can be seen that all devices are installed in different partitions on different moving parts. Specifically, when moving the automatic bolt lubrication and coating equipment, the universal wheel 15 is lowered, and the loading mobile frame 10 can move freely through the universal wheel 15 to drive the loading device 1 to move to the specified position. Similarly, the mobile production cabinet 9 and the unloading mobile frame 13 can drive the devices thereon to move to their respective specified positions, thereby facilitating the movement and assembly of the automatic bolt lubrication and coating equipment.

[0101] Considering the specific structure and installation method of the feeding device 1, based on the above embodiment, please refer to Figure 1 , Figures 2 to 6 The feeding device 1 includes a feeding component 11 and a dividing component 12.

[0102] The feeding assembly 11 includes a first head wheel 110 , a first tail wheel 111 , a first belt 112 and a first belt driver 113 . A closed-loop first belt 112 is sleeved outside the first head wheel 110 and the first tail wheel 111 . The first belt driver 113 is connected to the first head wheel 110 .

[0103] The material distribution assembly 12 includes a second head wheel 120 , a second tail wheel 121 , a second belt 122 and a second belt driver 123 . A closed-loop second belt 122 is sleeved on the outer sides of the second head wheel 120 and the second tail wheel 121 , and the second belt driver 123 is connected to the second head wheel 120 .

[0104] Among them, the first belt 112 is arranged higher than the second belt 122 and an inclined connecting plate 124 is provided between the two. The extension direction of the connecting plate 124 and the conveying direction of the second belt 122 are parallel to the arrangement direction of the two opposite side plates 31, and the position of the second belt 122 facing the two opposite side plates 31 is set as a grabbing station.

[0105] Thus, multiple bolts to be coated with glue can be placed manually on the first belt 112, and the first belt driver 113 drives the first belt 112 to transport the bolts backward. Under the action of their own weight, all the bolts slide one by one through the connecting plate 124 onto the second belt 122, and the second belt driver 123 drives the second belt 122 to transport the bolts to the grabbing station, so that the bolts are transported to the grabbing station, so that the feed picking device 2 can grab the bolts.

[0106] The feeding device 1 with the above-mentioned structural arrangement has the following effects: first, the inclined connecting plate 124 can make the bolts slide down by their own weight, ensuring that the bolts are smoothly transferred from the feeding component 11 to the distributing component 12, while avoiding the setting of additional transfer components, saving costs; second, the extension arrangement direction of the connecting plate 124 and the conveying direction of the second belt 122 are parallel to the arrangement direction of the two opposite side plates 31. Since a plurality of pairs of bolt slots 310 are arranged in sequence from front to back between the opposite side plates 31, the bolts are placed on the first belt 112 in parallel with the arrangement direction of the two side plates 31. The bolts then slide down through the connecting plate 124 and are then conveyed to the grabbing station through the second belt 122. This can better ensure that the bolts are still placed in parallel with the arrangement direction of the two side plates 31, so as to facilitate the feeding and picking device 2 to grab the bolts and place them on a pair of frontmost bolt slots 310.

[0107] It should be noted that the above-mentioned first belt drive 113 and second belt drive 123 are both connected to the control system electrical signal to realize remote automatic control of the feeding device 1, thereby realizing remote control of the power of the first belt drive 113 and the second belt drive 123, and further realizing precise control of the feeding rate of the bolts.

[0108] In this embodiment, please refer to Figure 3 The loading moving frame 10 includes a bottom frame 101 , a load-bearing material 102 and a belt mounting frame 103 .

[0109] The bottom frame 101 is composed of two bottom transverse profiles 1010 and two bottom longitudinal profiles 1011. The two bottom longitudinal profiles 1011 are fixed between the two bottom transverse profiles 1010 by screws and connected at 90 degrees, and the four joints are connected to the bottom ends of the four load-bearing profiles 102 by die-casting angles and screws. In addition, caster plates are installed at the four corners of the heads of the two bottom transverse profiles 1010, and a universal wheel 15 and a foot cup 14 are installed on each caster plate to realize the movement and fixation of the loading mobile rack 10.

[0110] Please refer to Figure 4The belt installation frame 103 is composed of two top transverse profiles 1030, two top longitudinal profiles 1031 and a belt support plate 1032. The two top longitudinal profiles 1031 are fixed in the middle of the two top transverse profiles 1030 by screws and connected at 90 degrees, and the four joints are correspondingly connected to the tops of the four load-bearing profiles 102 by die-casting angles and screws. The belt support plate 1032 is installed between the two top transverse profiles 1030 and located above the two top longitudinal profiles 1031. In addition, the first wheel seat 105 and the first wheel cover 106 are installed at the four corners of the head of the two top transverse profiles 1030, which are used to fix the first head wheel 110 and the first tail wheel 111. The first belt 112 connects the first head wheel 110 and the first tail wheel 111, and the wheel cover close to the first head wheel 110 is the head wheel cover, on which the first belt driver 113 is installed. Preferably, a first retaining edge 104 is installed on the top transverse profile 1030 to prevent the bolts from falling.

[0111] In summary, the loading movable frame 10 using the above-mentioned arrangement has good structural stability, and the feeding assembly 11 is arranged on the loading movable frame 10, which can ensure smooth and convenient transportation of the feeding assembly 11.

[0112] Further, considering the specific installation method of the material distribution component 12, in this embodiment, please refer to Figure 5 and Figure 6 , the material distribution assembly 12 also includes a material distribution mounting seat 129, a connecting seat 1210 and a belt support frame 1211. One side of the material distribution mounting seat 129 is fixed to the feeding end of the production cabinet 9 through the connecting seat 1210, and the other side of the material distribution mounting seat 129 is arranged adjacent to the discharging end of the first belt 112, and the material distribution mounting seat 129 is U-shaped, and the belt support frame 1211 is composed of two supporting profiles 1211a and a supporting plate 1211b. The two supporting profiles 1211a are relatively arranged between the two sides of the material distribution mounting seat 129 and connected by the supporting plate 1211b. The second wheel seat 1214 and the second wheel cover 1215 are arranged at the four corners of the head of the two supporting profiles 1211a, which are used to fix the second head wheel 120 and the second tail wheel 121, and the second belt 122 connects the second head wheel 120 and the second tail wheel 121, and the second belt driver 123 is arranged on the wheel cover close to the second head wheel 120.

[0113] In addition, the connecting plate 124 is connected to the feeding end of the first belt 112 and a supporting profile 1211a adjacent thereto, and the belt mounting frame 103 is higher than the belt support frame 1211, so that the first belt 112 is higher than the second belt 122, thereby making the connecting plate 124 tilt downward to facilitate the bolts to slide down. A second retaining edge 1216 is provided on the supporting profile 1211a on one side of the belt support frame 1211 away from the connecting plate 124 to prevent the bolts from falling.

[0114] Preferably, the belt mounting frame 103 is perpendicular to the belt support frame 1211, that is, the first belt 112 and the second belt 122 are perpendicular. Thus, the conveying direction of the first belt 112 can be perpendicular to the conveying direction of the second belt 122, so that the bolts are manually placed on the first belt 112 in a direction parallel to the conveying direction of the second belt 122 (i.e., the arrangement direction of the two opposite bolt slots 310). After being conveyed from the first belt 112 to the second belt 122, the bolts are still placed in a direction parallel to the arrangement direction of the two opposite bolt slots 310, so as to facilitate the loading of the bolts onto a pair of frontmost bolt slots 310.

[0115] Consider how to better ensure that the bolt moves to the grabbing position. Based on the above embodiment, please refer to Figure 5 A pusher driver 125 is provided on the side of the connecting plate 124 close to the grabbing station, and the output shaft of the pusher driver 125 is connected to a pusher block 1217 facing the grabbing station for positioning bolts.

[0116] Specifically, a pusher mounting plate 1212 is provided on the front profile, and the pusher mounting plate 1212 is opposite to the position between the two side plates 31 in the front-back direction, and the pusher mounting plate 1212 is located on the side of the connecting plate 124 close to the grabbing station, and the pusher driver 125 is fixed on the pusher mounting plate 1212, and the output shaft of the pusher driver 125 is connected to the pusher block 1217, and the pusher block 1217 is arranged opposite to the grabbing station. In this way, the bolt slides onto the second belt 122 through the connecting plate 124, and the bolt moves to the position of the pusher driver 125 under the drive of the second belt 122, and then moves accurately to the grabbing station under the push of the pusher driver 125, so as to facilitate the accurate grabbing of the feeding and picking device 2. It should be noted that the pusher driver 125 is connected to the control system electrical signal.

[0117] Considering how to determine whether the feeding component 11 is feeding, based on the above embodiment, please refer to Figure 5 A through hole 126 is provided on the connecting plate 124 , and a first sensor 127 is provided directly below the through hole 126 for identifying the bolts passing through the connecting plate 124 .

[0118] Specifically, a through hole 126 is provided on the connecting plate 124, and the first sensor 127 is installed on a material distribution mounting seat 129 located directly below the through hole 126. Thus, the first sensor 127 can identify the bolts passing through the connecting plate 124, and then determine whether the feeding assembly 11 is feeding. It should be noted that the first sensor 127 is connected to the control system by electrical signals.

[0119] Considering how to improve the material grabbing accuracy of the material picking device 2, based on the above embodiment, please refer to Figure 5 A second sensor 128 is provided at one end of the second belt 122 close to the grabbing station for identifying the position of the bolt.

[0120] Specifically, the belt support frame 1211 is provided with a sensor mounting block 1213 mounted at the end of the second head wheel 120, and the second sensor 128 is mounted on the sensor mounting block 1213. The distance between the second sensor 128 and the grabbing station is a preset sensing distance. If the bolt moves to the grabbing station, the second sensor 128 can identify the position of the bolt, so that the feeding picking device 2 can accurately grab the bolt. It should be noted that the second sensor 128 is connected to the control system by electrical signals.

[0121] In summary, when the feeding device 1 is in use, the bolt moves backwards driven by the first belt 112, and then automatically slides onto the second belt 122 through the inclined connecting plate 124. If the first sensor 127 recognizes the bolt and sends an identification signal to the control system, the bolt moves to the grabbing station driven by the second belt 122, and the push drive 125 drives the push block 1217 to push the bolt to the grabbing station. At this time, the second sensor 128 recognizes the position of the bolt and transmits it to the control system. The control system controls the feed picking device 2 to move to the grabbing station and accurately grabs the bolt. It should be noted that if the first sensor 127 cannot recognize the bolt, it means that no bolt has slipped onto the second belt 122. Not only can the push drive 125 be controlled not to act to save power, but it can also remind manual inspection of bolt conveying abnormalities to ensure continuous and uninterrupted feeding of the bolt.

[0122] The structures of the material input pick-up device 2 and the material output pick-up device of the present invention are consistent. Considering the specific structures of the two, the following description is made by taking the material input pick-up device 2 as an example. Figure 7 The feed picking device 2 includes a main frame 21, a first feed driver 22, a slide mounting plate 23, a second feed driver 24 and a pneumatic clamp 25. The first feed driver 22 is arranged on the top of the main frame 21 and connected to one side of the slide mounting plate 23, and is used to drive the slide mounting plate 23 to move forward and backward. The second feed driver 24 is arranged on the other side of the slide mounting plate 23 and is connected to the pneumatic clamp 25, and is used to drive the pneumatic clamp 25 to move up and down.

[0123] Therefore, when the feeding and picking device 2 is used to transport bolts, the first feeding driver 22 drives the slide mounting plate 23 to move forward, and the slide mounting plate 23 drives the pneumatic clamp 25 to move forward until the pneumatic clamp 25 moves to the top of the grabbing station, and then the second feeding driver 24 drives the pneumatic clamp 25 to descend. After the pneumatic clamp 25 grabs the bolt, the second feeding driver 24 drives the pneumatic clamp 25 to rise again, and then the first feeding driver 22 drives the slide mounting plate 23 to move backward, and the slide mounting plate 23 drives the pneumatic clamp 25 to move backward until the pneumatic clamp 25 carries the bolt to the top of a pair of front end bolt slots 310, and finally the second feeding driver 24 drives the pneumatic clamp 25 to descend, and after placing the bolt in a pair of front end bolt slots 310, the second feeding driver 24 drives the pneumatic clamp 25 to rise, and the above steps are repeated to continuously and uninterruptedly grab the bolt.

[0124] It should be noted that the first feed drive 22 and the second feed drive 24 are both connected to the control system by electrical signals, which can not only realize remote automatic control, but also accurately move the bolts to ensure that the bolts are transferred from the gripping station to a pair of front-end bolt slots 310.

[0125] In this embodiment, please refer to Figure 7 The main frame 21 is composed of two vertical support profiles 1211a, two horizontal support profiles 1211a and one oblique support profile 1211a. The bottom ends of the two vertical support profiles 1211a are connected to the top surface of the production cabinet 9 by extruding angles, and one horizontal support profile 1211a is connected between the middle parts of the two vertical support profiles 1211a by extruding angles. Another horizontal support profile 1211a is connected between the tops of the two vertical support profiles 1211a by extruding angles. The side of the middle part of a vertical support profile 1211a is connected to the horizontal support profile 1211a at the top through an oblique support aluminum material. The main frame 21 with this structural setting has high bearing strength, thereby ensuring that the structure of the input pick-up device 2 or the discharging pick-up device is stable, thereby ensuring the smooth transportation of bolts.

[0126] In this embodiment, please refer to Figure 7 , a feed mounting plate 26 is arranged on the top side of the main frame 21, a first feed driver 22 is arranged on the feed mounting plate 26, and feed guide rails 27 are respectively arranged on the feed mounting plates 26 located on the upper and lower sides of the first feed driver 22, the first feed driver 22 and the two feed guide rails 27 are both extended and arranged in the front-to-back direction, the piston of the first feed driver 22 is directly connected to one side of the slide mounting plate 23, and the upper and lower ends of the slide mounting plate 23 are correspondingly slidably matched with the two feed guide rails 27 through sliders. Therefore, the use of this structure to set the first feed driver 22 not only saves installation space, but also enables the slide mounting plate 23 to move forward and backward accurately and smoothly, thereby achieving accurate and smooth forward and backward movement of the bolts.

[0127] In this embodiment, please refer to Figure 7 , the second feed driver 24 is arranged at the top of the slide mounting plate 23. The second feed driver 24 is an embedded slide module. Its specific structure can refer to the prior art, and can achieve precise linear motion and position control. A tripod 28 is provided on the slider of the embedded slide module, and the pneumatic clamp 25 is arranged at the bottom of the tripod 28 through the mounting plate. Therefore, the second feed driver 24 and the pneumatic clamp 25 arranged in this structure not only save installation space, but also enhance the stability of the pneumatic clamp 25 structure, thereby ensuring that the pneumatic clamp 25 firmly clamps the bolt. Further preferably, an extension block 29 is provided at the lower part of the pneumatic clamp 25 to facilitate the clamping of the bolt.

[0128] Optionally, the drag chain 210 is arranged in the drag chain groove 211 at the top of the main frame 21 and extends along the front-to-back direction. The rear end of the drag chain 210 is connected to the second feed drive 24, which can further guide the forward and backward movement of the slide mounting plate 23.

[0129] Considering the specific structure and installation method of the feeding device 3, based on the above embodiment, please refer to Figure 8 The two side panels 31 are both extended in the front-to-back direction, that is, extended in the length direction of the production cabinet 9, and the two side panels 31 are fixed on the top surface of the production cabinet 9 at a certain distance, and a bolt moving frame 32 is placed in the interval.

[0130] Furthermore, in the present embodiment, the bolt moving frame 32 includes a fixed plate 320 , a moving plate 321 , two bolt placing frames 323 , two lifting notch blocks 324 and a vertical moving driver 325 .

[0131] Among them, please refer to Figure 8 The fixed plate 320 and the movable plate 321 are specifically configured as follows: the fixed plate 320 is located in the internal space of the production cabinet 9 and is fixedly connected to the top of the production cabinet 9 through four aluminum bars 326, a horizontal movable driver 322 is arranged on the lower end surface of the fixed plate 320, a transfer guide rail 327 extending in the front-rear direction is arranged on the upper end surface of the fixed plate 320, and a transfer slider 328 slidingly matched with the transfer guide rail 327 is arranged on the lower end surface of the movable plate 321, so that the movable plate 321 is slidably connected with the fixed plate 320. In addition, a long strip 329 is arranged at the end of the movable plate 321 away from the horizontal movable driver 322, and the long strip 329 penetrates the slot on the fixed plate 320 to set a first floating joint 3210, and the first floating joint 3210 is directly opposite to the output shaft of the horizontal movable driver 322, so that the output shaft of the horizontal movable driver 322 is connected to the first floating joint 3210 to drive the movable plate 321 to move forward and backward relative to the fixed plate 320.

[0132] Please refer to Fig. 9 The specific structure of the two bolt placement racks 323 is as follows: the top of each bolt placement rack 323 is provided with a plurality of slots 3216 arranged along the front-to-back direction, and the spacing between two adjacent slots 3216 is the same as the spacing between two adjacent bolt slots 310, and this spacing is called spacing A. In this way, the two bolt placement racks 323 can drive all the bolts to move backward by the spacing A at the same time, and then descend to place all the bolts on the next pair of bolt slots 310.

[0133] Please refer to Fig. 9 and Fig.10 The specific installation of the two bolt placement racks 323 is as follows: the two bolt placement racks 323 are located on the inner sides of the two side plates 31, and a lifting notch block 324, a vertical moving driver 325 and another lifting notch block 324 are sequentially arranged on the upper end surface of the moving plate 321 along the front-back direction. Notches are arranged on both sides of the two lifting notch blocks 324, and long rails 3211 are arranged in the notches. The two opposite inner sides of the two bolt placement racks 323 are slidably matched with the two long rails 3211 through connecting sliders 3212. In addition, a crossbeam 3213 is connected between the two bolt placement racks 323, and a second floating joint 3214 is arranged at the position of the crossbeam 3213 facing the vertical moving driver 325, so that the output shaft of the vertical moving driver 325 is connected to the second floating joint 3214 to drive the two bolt placement racks 323 to move up and down together.

[0134] It should be noted that the horizontal moving driver 322 and the vertical moving driver 325 are both connected to the control system electrical signal, which can not only realize remote automatic control, but also accurately move the two bolt placement racks 323 to ensure that the bolts are placed one by one on each pair of bolt slots 310.

[0135] Preferably, a fourth sensor 3215 is provided at a position of the side plate 31 adjacent to any middle bolt slot 310 for identifying the bolt. Fig. 9 The fourth sensor 3215 is connected to the control system by electrical signals. If a bolt is placed on a pair of middle bolt slots 310, the fourth sensor 3215 identifies the bolt and transmits a signal to the control system. The control system then controls the bolt rotating device 6, the head gluing device 4 and the tail gluing device 5 to act on the bolt at the same time to complete the bolt gluing operation.

[0136] In order to achieve uniform grease application on the bolts, based on the above embodiment, the present invention further includes a bolt rotating device 6, the driving end of which is rotatable and liftable and is arranged above the two opposite middle bolt slots 310, for driving the bolts to rotate, and two spaced rollers 311 are arranged in each bolt slot 310, or two spaced rollers 311 are arranged in the two opposite middle bolt slots 310, such as Figure 8 and Fig.10 shown.

[0137] It can be understood that the middle bolt slot 310 on the two side plates 31 is set as a coating station, and two spaced rollers 311 are set in the middle bolt slot 310, so that the screw end of the bolt can be rotatably placed between the two rollers 311, that is, the bolt can be rolled and placed. Alternatively, two spaced rollers 311 are set in all bolt slots 310, so that the bolt can be rotatably placed on any pair of bolt slots 310, which is convenient for adjusting the coating station to suit different coating conditions.

[0138] Both of the above two roller 311 setting methods can realize the rotatable setting of the bolt. In this way, the bolt rotates under the drive of the bolt rotating device 6, so that the head gluing device 4 evenly applies grease to the screw head of the bolt, and the tail gluing device 5 evenly applies grease to the screw tail of the bolt, thereby realizing uniform gluing of the screw.

[0139] Regarding the specific structure and installation method of the bolt rotating device 6, based on the above embodiment, please refer to Fig.11 The bolt rotating device 6 includes a bracket 61 , a first rotating driver 62 , a second rotating driver 64 and a rolling wheel 69 .

[0140] Among them, the bracket 61 is arranged on the side of the side plate 31 adjacent to the screw head; the first rotation driver 62 is arranged on the top of the bracket 61 and connected to the first mounting plate 63, which is used to drive the mounting plate to rise and fall; the second rotation driver 64 is arranged on the top of the first mounting plate 63, and the bottom of the first mounting plate 63 is provided with a rotating shaft 65, and the main synchronous pulley 66 on the output shaft of the second rotation driver 64 is connected to the secondary synchronous pulley 68 on the rotating shaft 65 through a synchronous belt 67; the rolling wheel 69 is sleeved on the rotating shaft 65 and faces the position between the two opposite middle bolt slots 310.

[0141] It can be seen that the first rotary driver 62 drives the first mounting plate 63 to rise and fall, and the first mounting plate 63 drives the rolling wheel 69 to rise and fall, so as to achieve the movement of the rolling wheel 69 close to or away from the bolt, and to prevent the rolling wheel 69 from interfering with the backward movement of the bolt. The second rotary driver 64 is connected to the rotating shaft 65 with a different axis through the synchronous pulley structure 512 to drive the rotating shaft 65 to rotate, thereby achieving the rotation of the rolling wheel 69, and then the rolling wheel 69 drives the spiral to rotate when it contacts the bolt.

[0142] It should be noted that both the first rotary driver 62 and the second rotary driver 64 are connected to the control system via electrical signals to achieve remote automated control of the bolt rotating device 6 .

[0143] In this embodiment, please refer to Fig.11The bracket 61 is composed of an L-shaped bracket 610 and a transverse plate 611.

[0145] In this way, after the bolt is placed on a pair of middle bolt slots 310, the head glue application driver 43 drives the head glue dispensing valve 44 to move toward the screw head, and the head glue dispensing valve 44 applies grease to the screw head, thus completing the gluing of the screw head.

[0146] It should be noted that the head glue application driver 43 and the head glue dispensing valve 44 are both connected to the control system via electrical signals, so as to realize remote automatic control of the head glue application device 4 to perform glue application.

[0148] Among them, the movable platform 51 is adjacent to the side plate 31 for placing the tail of the screw, and is arranged on the top surface of the production cabinet 9 to move toward or away from the middle bolt slot 310 (that is, along the vertical side plate 31 or the length direction of the production cabinet 9); the brush seat 52 is arranged on the movable platform 51 and faces another middle bolt slot 310, and three brushes 53 are arranged in a herringbone shape on one side of the brush seat 52 and form a space for inserting the tail of the screw; the brush driver 54 is arranged on the other side of the brush seat 52 and connected to the top brush 53, and is used to drive the top brush 53 to rotate; the tail dispensing valve 55 is arranged at the top of the brush seat 52 and inserted into the top brush 53.

[0149] In this way, after the bolt is placed on a pair of middle bolt slots 310, the moving platform 51 moves toward the middle bolt slots 310, so that the tail of the screw is inserted into the space formed by the three brushes 53 arranged in a triangular shape, and the brush driver 54 drives the top brush 53 to rotate, and the tail dispensing valve 55 drips grease to the top brush 53, and the top brush 53 applies the grease to the tail of the screw, and then cooperates with the other two brushes 53 to make the grease evenly applied to the rotating tail of the screw. In addition, the brush seat 52 is provided with a splash shield 514 that covers the outer periphery of the three brushes 53, and the splash shield 514 is set to an opening on the side of the side plate 31, so that when the brush 53 applies glue to the tail of the screw, the splash shield 514 plays a role in preventing grease from splashing.

[0150] In this embodiment, please refer to Fig.13 , both sides of the bottom end of the moving platform 51 are provided with glue-coating sliders 59, and the production cabinet 9 is provided with two glue-coating guide rails 58 corresponding to the two glue-coating slide rails for sliding connection, so that the moving platform 51 can be slid forward and backward on the top surface of the production cabinet 9 through the guide rail slider structure, and the internal space of the production cabinet 9 is provided with a tail glue-coating driver, and the output end of the tail glue-coating driver is connected to the lead screw 510, and the lead screw 510 is arranged along the length direction of the vertical side plate 31 (that is, along the length direction of the vertical production cabinet 9), and the end of the workbench away from the tail glue-coating driver is provided with an insert block 513 extending into the interior of the production cabinet 9, and the insert block 513 is threadedly sleeved with the lead screw 510. In this way, the tail glue-coating driver drives the lead screw 510 to rotate, and the lead screw 510 can drive the insert block 513 to move linearly thereon, thereby driving the moving platform 51 to move toward or away from the middle bolt slot 310.

[0151] Preferably, the tail gluing driver is composed of a servo motor 511 and a synchronous pulley structure 512 , so that the driver is connected to the lead screw 510 through the synchronous pulley structure 512 .

[0152] It should be noted that the tail glue coating driver, the brush driver 54 and the tail glue dispensing valve 55 are all connected to the control system via electrical signals to achieve remote automatic control of the tail glue coating device 5 to perform glue coating.

[0153] To achieve glue coating operation on bolts of different lengths, please refer to Fig.14 A sensor rail 57 extending along the front-to-back direction is provided on one side of the moving platform 51 , and a third sensor 56 is slidably connected to the sensor rail 57 .

[0154] It is understandable that the third sensor 56 can identify the position of the tail of the screw to determine the moving distance of the moving platform 51 toward the tail of the screw, thereby ensuring that the moving platform 51 drives the three brushes 53 to wrap the tail of the screw, thereby ensuring that the tail of the screw thread is coated with glue. If the length of the bolt changes, according to the length of the screw and its own recognition range, the third sensor 56 is moved forward and backward along the sensor guide rail 57 to fix the third sensor 56 at a suitable position of the sensor guide rail 57. In this way, no matter whether the length of the bolt increases or decreases, the third sensor 56 can identify the position of the tail of the screw to be suitable for gluing operations of screws of different lengths.

[0155] It should be noted that the third sensor 56 is connected to the control system by electrical signals, so that the third sensor 56 recognizes the position of the screw tail and transmits it to the control system, and the control system controls the distance of the moving platform 51 toward the screw tail according to the acquired position information.
