Description

载具吸吹循环自动锁螺丝机Carrier suction and blow cycle automatic screw locking machine 技术领域Technical field
本发明涉及上螺丝自动设备技术领域，具体涉及一种载具吸吹循环自动锁螺丝机。The invention relates to the technical field of automatic screw loading equipment, and in particular to an automatic screw locking machine with a suction and blow cycle for a carrier.
背景技术Background technique
螺丝是机械设备和电子设备组装过程中必不可少的五金标准件，在一台机械设备上可能有几十个、以致于几百个螺丝要锁付，为了提高工作效率，减轻工人的劳动负担，人们发明了自动锁螺丝机。Screws are essential hardware standard parts in the assembly process of mechanical equipment and electronic equipment. There may be dozens or even hundreds of screws to be locked on a piece of mechanical equipment. In order to improve work efficiency and reduce the labor burden of workers, , people invented the automatic screw locking machine.
“气吹式”自动螺丝机的问世，因为可以做到自动补料，大大提高工作效率，手持式自动螺丝机，操作灵活简便，例如公开号为CN204524739U的中国专利公开了一种具有一级缓冲装置的吹气式自动锁螺丝机，由机台、X轴模组、Y轴模组、Z轴模组、螺丝机头、X轴模组支架和吹气式供料装置组成，所述Y轴模组有两组，分别水平安装在机台的上平面，用来驱动工作台的前后位移，形成了双工位操作台；所述X轴模组水平安装在机台后面的X轴模组支架上，用来驱动螺丝机头的左右位移；所述Z轴模组垂直安装在所述X轴模组上，用来驱动螺丝机头的上下位移；所述吹气式供料装置分别安装在Z轴模组和机台的上面。The advent of the "air-blown" automatic screw machine greatly improves work efficiency because it can automatically replenish materials. The hand-held automatic screw machine is flexible and easy to operate. For example, the Chinese patent with publication number CN204524739U discloses a first-level buffer The air-blowing automatic screw locking machine of the device is composed of a machine table, an X-axis module, a Y-axis module, a Z-axis module, a screw head, an X-axis module bracket and an air-blowing feeding device. The Y There are two sets of axis modules, which are installed horizontally on the upper plane of the machine platform to drive the front and rear displacement of the workbench, forming a dual-station operating platform; the X-axis module is installed horizontally on the X-axis module behind the machine platform. The set of brackets is used to drive the left and right displacement of the screw head; the Z-axis module is installed vertically on the X-axis module and is used to drive the up and down displacement of the screw head; the air blowing feeding device is respectively Installed on the Z-axis module and machine table.
但是有明显的局限性：But there are obvious limitations:
(1)需要将螺丝锁付模块固定在XYZ模组或四轴机械臂上，能够按照设定程序自动锁付螺丝，但是每锁付一个螺丝后都要回到螺丝供料器取料，大量时间消耗在取料动作上，严重影响效率；(1) The screw locking module needs to be fixed on the XYZ module or the four-axis robotic arm. It can automatically lock the screws according to the set program. However, after each screw is locked, it must be returned to the screw feeder to retrieve materials. A large number of Time is consumed in the retrieval action, seriously affecting efficiency;
(2)因为采用磁吸式即利用批头的磁性吸住螺丝，只能适用于铁质螺丝；(2) Because the magnetic suction type uses the magnetism of the bit to hold the screws, it can only be applied to iron screws;
(3)螺丝的输送管道是用最常见的圆形高压风塑料软管，采用压缩空气将螺丝通过输送管道吹送到螺丝夹头，螺丝在输送过程中经过输送管和夹头，必须要保持“头上脚下”即螺丝的帽头在上螺丝末端在下，为此只能用在细长螺丝(螺丝长度至少是帽头直径的1.2倍)，否则会在输送过程中会发生翻转；(3) The screw transportation pipeline uses the most common round high-pressure air plastic hose. Compressed air is used to blow the screws through the transportation pipeline to the screw chuck. During the transportation process, the screws pass through the transportation pipe and the chuck, and must be kept " "Head and foot" means that the cap head of the screw is on the top and the end of the screw is on the bottom. For this reason, it can only be used on slender screws (the length of the screw is at least 1.2 times the diameter of the cap head), otherwise it will flip over during transportation;
(4)输送管道内径和夹头上方螺丝通孔的内径大小必须要和螺丝匹配，过大螺丝会翻转过小螺丝不能通过，实际上每台螺丝机为某个特定的螺丝量身定做，通用性很差，而螺丝的种类非常多，尤其是螺丝帽头直径千差万别，这就大大限制了螺丝机的使用范围，尤其是现在产品更新换代越来越快，产品更新换代后所用的螺丝也会改变，原先的螺丝机就用不上了。(4) The inner diameter of the conveying pipe and the inner diameter of the screw hole above the chuck must match the screw. Oversized screws will flip over and small screws cannot pass. In fact, each screw machine is tailor-made for a specific screw and is universal. The performance is very poor, and there are many types of screws, especially the diameters of the screw cap heads. This greatly limits the scope of use of the screw machine. Especially now that product updates are getting faster and faster, the screws used after product updates will also After the change, the original screw machine will no longer be used.

The discharging module base 241 is also installed with an alignment mounting plate 245. The discharging module base 241 is docked and fixed with the chuck fixing base 32 through the alignment mounting plate 245, which facilitates the docking installation of the discharging module base 241 and the chuck mechanism 3.
参照图9和图10所示，螺丝载具26包括载具本体261，所述载具本体261的横向截面设置成非圆周形中的椭圆形，载具输送管25的管道截面也对应设置成椭圆形，所述载具本体261的前侧面上开设有T型槽262，所述载具本体261的后侧面上开设有与T型槽262相连通的吹风孔263。椭圆形的设计加工容易而且可以有效避免在输送过程中椭圆形截面发生横向方位上的偏转。通过在载具本体261的后侧面上开设有与T型槽262相连通的吹风孔263，实际卸料时，可以通过吹风孔263处吹气，将螺丝由T型槽262内从载具本体261的前侧面出料。通过将载具本体261的横向截面设置成非圆周形，可以使得载具本体261在非圆周形的载具输送管25内不会轻易转动，如果是设计成圆形的话，螺丝载具26在输送过程中很容易发生横向方位上的偏转，这样一来，在螺丝进料和螺丝出料处，就需要加装载具二次定位的复杂机构，结构复杂臃肿，无法实行手持操作。通过在载具本体261的前侧面上开设有T型槽262，便于装载各种类型的螺丝，只要螺丝头及螺丝柱不超过T型槽262最大或者最小的极限要求即可，相比传统的只能一种输送管道匹配单一的一种类型的螺丝，其适应性大大增强。Referring to Figures 9 and 10, the screw carrier 26 includes a carrier body 261. The transverse cross-section of the carrier body 261 is set to an elliptical shape in a non-circular shape, and the cross-section of the carrier delivery pipe 25 is also correspondingly set to Oval shape, the front side of the carrier body 261 is provided with a T-shaped slot 262, and the rear side of the carrier body 261 is provided with a blowing hole 263 connected with the T-shaped slot 262. The elliptical design is easy to process and can effectively avoid lateral deflection of the elliptical cross-section during transportation. A blowing hole 263 connected to the T-shaped slot 262 is provided on the rear side of the carrier body 261. During actual unloading, air can be blown through the blowing hole 263 to remove the screws from the carrier body through the T-shaped slot 262. The front side of 261 is discharged. By setting the transverse cross-section of the carrier body 261 to a non-circular shape, the carrier body 261 will not easily rotate in the non-circular carrier conveying tube 25. If it is designed to be circular, the screw carrier 26 will During the transportation process, it is easy to deflect in the lateral direction. As a result, at the screw feeding and screw discharging points, a complex mechanism for secondary positioning of the loader needs to be added. The structure is complex and bloated and cannot be operated by hand. By providing a T-shaped slot 262 on the front side of the carrier body 261, it is convenient to load various types of screws, as long as the screw heads and screw columns do not exceed the maximum or minimum limit requirements of the T-shaped slot 262. Compared with the traditional Only one type of delivery pipe can be matched with a single type of screw, which greatly enhances its adaptability.
本实施例中，载具本体261的横向截面还可以设置成非圆周形中的六边形或者四边形，载具输送管25的管道截面也对应设置成六边形或者四边形，其主要目的是保证载具本体261在高压风的吹送过程中，载具本体261不会因为转动而造成T型槽262的位置偏转，避免螺丝无法进入T型槽262或者无法从T型槽262出料。In this embodiment, the transverse cross-section of the carrier body 261 can also be set in a non-circular hexagon or quadrilateral, and the cross-section of the carrier delivery pipe 25 can also be set in a hexagon or quadrilateral. The main purpose is to ensure When the carrier body 261 is blown by high-pressure wind, the carrier body 261 will not cause the position of the T-shaped slot 262 to deflect due to rotation, preventing the screw from being able to enter the T-shaped slot 262 or the material from being unable to be discharged from the T-shaped slot 262.

设有磁力吸附模块44的螺丝锁付机构4在实际工作时：气缸423带动所述架体固定座和夹头机构3下行，电批头426相对夹头机构3往上移动，直至电批头426的下端缩回到夹头机构3的顶部。然后，所述出料机构后侧面的吹料气嘴15将螺丝载具26内的螺丝从出料机构前侧面的T型出料槽244经由夹头机构3上的T型进料槽吹入夹头机构3内。需要进行锁付螺丝时，气缸423带动夹头固定座32上行，电批头426旋转着从夹头机构3中往下伸出。往上移动的夹头机构3将磁力安装座441往上顶起，使得磁座压紧簧444被压缩。在这过程中，电批头426抵住螺丝顶开左半夹头311和右半夹头312。而由于电批头426始终穿设于环形磁铁443中，电批头426带有磁性能够将螺丝吸附在电批头426的下端。当批头扭力达到设定值，锁付完毕，批头离开锁付工位后，气缸423带动夹头固定座32下行，进行下一个螺丝的锁付。When the screw locking mechanism 4 equipped with the magnetic adsorption module 44 is actually working: the cylinder 423 drives the frame fixing seat and the chuck mechanism 3 downward, and the electric bit 426 moves upward relative to the chuck mechanism 3 until the electric bit The lower end of 426 is retracted to the top of the collet mechanism 3. Then, the blowing air nozzle 15 on the rear side of the discharging mechanism blows the screws in the screw carrier 26 from the T-shaped discharging slot 244 on the front side of the discharging mechanism through the T-shaped feeding slot on the chuck mechanism 3 Inside the chuck mechanism 3. When it is necessary to tighten the screws, the cylinder 423 drives the chuck holder 32 upward, and the electric bit 426 rotates and extends downward from the chuck mechanism 3 . The upward moving chuck mechanism 3 pushes up the magnetic mounting base 441, causing the magnetic base compression spring 444 to be compressed. During this process, the electric bit 426 resists the screw and pushes open the left half chuck 311 and the right half chuck 312 . Since the electric bit 426 is always inserted into the annular magnet 443, the electric bit 426 has magnetism and can attract the screws to the lower end of the electric bit 426. When the bit torque reaches the set value, locking is completed, and after the bit leaves the locking station, the cylinder 423 drives the chuck holder 32 downward to lock the next screw.
所述导向柱442的下端设有限位块。所述导向柱442的长度根据气缸423行程来设置，夹头固定座32的行程超出磁力安装座441的行程一定距离为佳。当气缸423带动夹头固定座32下行时，磁力安装座441到达下极限位置，其下端与限位块抵接。这时气缸423仍带动夹头固定座32下行，夹头固定座32相对于磁力安装座441往下移动，也即左夹体331和右夹体332能够相对于导向件333往下移动，安装在左夹体331和右夹体332的驱动端334上的滚轮能够在夹紧弹簧的作用下沿导轨槽3331滚动。所述导轨槽3331包括夹持段和进料段。所述进料段设于导轨槽3331的下端，所述夹持段设于进料段的上侧。所述夹持段沿上下方向延伸。两个导轨槽3331的所述进料段相向靠近延伸。The lower end of the guide column 442 is provided with a limiting block. The length of the guide post 442 is set according to the stroke of the cylinder 423. It is better that the stroke of the chuck fixing base 32 exceeds the stroke of the magnetic mounting base 441 by a certain distance. When the air cylinder 423 drives the chuck fixing base 32 downward, the magnetic mounting base 441 reaches the lower limit position, and its lower end contacts the limiting block. At this time, the cylinder 423 still drives the chuck holder 32 downward, and the chuck holder 32 moves downward relative to the magnetic mounting seat 441. That is, the left clamp body 331 and the right clamp body 332 can move downward relative to the guide 333, and the installation The rollers on the driving ends 334 of the left clamp body 331 and the right clamp body 332 can roll along the guide groove 3331 under the action of the clamping spring. The guide rail groove 3331 includes a clamping section and a feeding section. The feed section is provided at the lower end of the guide rail groove 3331, and the clamping section is provided on the upper side of the feed section. The clamping section extends in the up and down direction. The feeding sections of the two guide rail grooves 3331 extend toward each other.
当安装在驱动端334的滚轮抵紧在夹持段时，左夹体331和右夹体332的下端相向抵紧合拢。当安装在驱动端334的滚轮沿所述进料段往下移动时，所述左夹体331和右夹体332的驱动端334在导轨槽3331的作用下相互靠近，左夹体331和右夹体332的下端相互远离而张开，所述左联动臂3311和右联动臂3321相向靠近，使得所述左半夹头311的上端和右半夹头312的上端受到挤压而相向靠近，左半夹头311和右半夹头312的下端张开一定距离，使得两个Γ形槽3114能够相互张开，螺丝更容易从T型出料槽244吹入到T型进 料槽内。当夹头固定座32移动到下极限位置后，螺丝从出料机构吹入到夹头机构3后，会落入左半夹头311和右半夹头312之间的空间内，螺丝的下端会从左半夹头311和右半夹头312合拢形成的圆孔中伸出。When the roller installed on the driving end 334 is pressed against the clamping section, the lower ends of the left clamp body 331 and the right clamp body 332 are pressed against each other and closed. When the roller installed on the driving end 334 moves downward along the feeding section, the driving ends 334 of the left clamp body 331 and the right clamp body 332 approach each other under the action of the guide groove 3331, and the left clamp body 331 and the right clamp body 332 move closer to each other. The lower ends of the clamp body 332 are spread apart from each other, and the left linkage arm 3311 and the right linkage arm 3321 are close to each other, so that the upper ends of the left half clamp 311 and the right half clamp 312 are squeezed and approach each other. The lower ends of the left half chuck 311 and the right half chuck 312 are opened at a certain distance, so that the two Γ-shaped grooves 3114 can open to each other, and the screws are more easily blown into the T-shaped feed chute from the T-shaped outlet chute 244. When the chuck holder 32 moves to the lower limit position, the screw is blown into the chuck mechanism 3 from the discharging mechanism, and then falls into the space between the left half chuck 311 and the right half chuck 312. The lower end of the screw It will protrude from the circular hole formed by the closing of the left half clamp 311 and the right half clamp 312.
在气缸423带动夹头固定座32上行时，夹头固定座32相对磁力安装座441往上移动。左夹体331和右夹体332上端的滚轮沿导轨槽3331往上移动，在夹紧弹簧的作用下，左夹体331和右夹体332的下端相互靠近合拢，对伸出夹头组件31下侧的螺丝进行整理，从而让电批头426的端部能够与螺丝的螺丝帽对齐，确保电批头426能够对螺丝成功锁付。与此同时，左联动臂3331和右联动臂3321相互远离，左半夹头311和右半夹头312也能在复位弹簧的作用下相互合拢，从而避免螺丝从T型进料槽掉出，导致异常。When the air cylinder 423 drives the chuck holder 32 upward, the chuck holder 32 moves upward relative to the magnetic mounting base 441. The rollers at the upper ends of the left clamp body 331 and the right clamp body 332 move upward along the guide groove 3331. Under the action of the clamping spring, the lower ends of the left clamp body 331 and the right clamp body 332 are close to each other, and the clamp assembly 31 extends out. The screws on the lower side are arranged so that the end of the electric bit 426 can be aligned with the nut of the screw to ensure that the electric bit 426 can successfully lock the screw. At the same time, the left linkage arm 3331 and the right linkage arm 3321 move away from each other, and the left half chuck 311 and the right half chuck 312 can also close each other under the action of the return spring, thereby preventing the screws from falling out of the T-shaped feed slot. Cause exception.
左夹体331和右夹体332通过左联动臂3311和右联动臂3321，能够与所述左半夹头311和右半夹头312实现同步开合，从而螺丝进料后能够将螺丝限制在特定位置，确保电批头426的端部能够与螺丝的螺丝帽对齐，大大提高锁付稳定性。The left clamp body 331 and the right clamp body 332 can be opened and closed synchronously with the left half clamp 311 and the right half clamp 312 through the left linkage arm 3311 and the right linkage arm 3321, so that the screw can be limited after the screw is fed. The specific position ensures that the end of the electric bit 426 can be aligned with the nut of the screw, greatly improving the locking stability.
