Description

Technical Field

[0001] The utility model belongs to the technical field of screw locking equipment, and in particular relates to an improvement of the structure of a screw locking system. Background Art

[0002] When small parts are locked onto a PCB board, screw locking operations are required. Currently, automatic screw locking is mainly achieved through a locking mechanism. The existing locking mechanism structure is mainly to set up a single locking device, which absorbs the screws through the locking device, and then the electric screwdriver of the locking device drives the electric screwdriver rod to rotate to perform the screw locking operation.

[0003] Since the PCB board is thin and has poor rigidity, in order to prevent the locking device from applying too much force to the PCB board at one time during screw locking, which may cause damage to the PCB board, it is necessary to first perform pre-locking through the locking device, and then stay for a certain period of time after the pre-locking is completed, and then use the locking device to complementarily tighten again to complete the complete locking operation of the screw. When a single locking device is used for locking, since the locking cannot be completed at one time and needs to stay in the middle, the efficiency of the locking operation is greatly reduced, which reduces the overall production efficiency.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0162] When the input motor 610 rotates, it can drive the input transmission member 620 to rotate, and then drive the active input sprockets 630 arranged at both ends to rotate, drive the redirecting input sprockets 640 groups and the driven transmission sprocket group on both sides to rotate, and the input chain 354 located above it moves to transport the material plate.

[0163] The output conveyor line 700 is connected to the locking conveyor module 520 and is used to output the material plate in the locking conveyor module 520 from the locking flipping and positioning module. The output conveyor line 700 has the same structure as the input conveyor line 600.

[0164] When the screw locking system is working, the material plate is conveyed to the pre-locking conveying module 300 through the input conveying line 600, and the pre-locking conveying module 300 conveys the material plate to the pre-locking positioning module 200, and the material plate is clamped by the pre-locking positioning module 200, and then the pre-locking flipping power module 270 drives the pre-locking positioning module 200 and the pre-locking conveying module 300 to flip 180 degrees, and the pre-locking device 400 performs a screw pre-locking operation on the back of the material plate;

[0165] After the pre-locking is completed, the pre-locking positioning module 200 and the pre-locking conveying module 300 are reversely flipped by the flipping power module 270 to reset them, and then the pre-locking positioning module 200 is released, and the pre-locking conveying module 300 conveys the material plate to the locking conveying module 520, and the material plate is continued to be clamped by the locking positioning module 510, and then the locking positioning module 510 and the locking conveying module 520 are flipped, and locked by the locking device 530. After the locking is completed, it is reversed and reset, and then the material plate is transported outward by the locking conveying module 520 and output through the output material line. The material plate is always positioned during the flipping process to ensure the position accuracy of the material plate when it is transported to the next process.

[0166] In some embodiments of the present application, the pre-locking device 400 of the screw locking system is assembled on the body 100.

[0167] It includes: a pre-locked three-way moving module 410;

[0168] And a double-head pre-locking module 420 connected to the pre-locking three-way moving module 410.

[0169] In some embodiments of the present application, the pre-locked three-way movable module 410 includes a pre-locked X-way movable module 411, a pre-locked Y-way movable module 412 and a pre-locked Z-way movable module 413, wherein both ends of the pre-locked Y-way movable module 412 are respectively connected to the end support frame at one end, the pre-locked X-way movable module 411 is arranged perpendicular to the pre-locked Y-way movable module, and is connected to the end of the Y-way movable module, and the other end is fixed on the middle support frame.

[0170] The pre-locking Z-direction moving module 413 is connected to the pre-locking X-direction moving module 411 and can move linearly under the drive of the pre-locking X-direction moving module 411 .

[0171] The pre-locking X-direction moving module 411 , the pre-locking Y-direction moving module 412 , and the pre-locking Z-direction moving module 413 can directly adopt the existing linear module structure, which will not be described in detail herein.

[0172] The locking device 530 is assembled on the body 100 and includes: a locking three-way moving module 531;

[0173] In some embodiments of the present application, the locking three-way movable module 531 includes a locking X-way movable module, a locking Y-way movable module and a locking Z-way movable module, wherein the two ends of the locking X-way movable module are respectively connected to the end support frame at the other end, the locking Y-way movable module is vertically pre-locked with the X-way movable module and connected to the end of the X-way movable module, and the other end is fixed on the middle support frame.

[0174] The locking device 530 further includes: a double-head locking module 532 connected to the locking three-way moving module 531 , and the double-head locking module 532 is disposed opposite to the double-head pre-locking module 420 .

[0175] The locking three-way moving modules 531 and the locking three-way moving modules 531 are connected and surrounded to form a containing space;

[0176] By docking the pre-locking three-way movable module 410 and the locking one-way movable module and arranging the locking device 530 and the pre-locking device 400 relatively, a space for convenient operation is formed between the four.

[0177] At the same time, the input conveyor line 600, the pre-locking positioning module 200, the locking positioning module 510 and the output conveyor line 700 are all arranged in the accommodating space and arranged in sequence along the material conveying direction, so that the pre-locking device 400, the locking device 530 for locking and the pre-locking positioning module 200, the locking positioning module 510, the input conveyor line 600 and the output conveyor line 700 for locking are all integrated in the area formed by the accommodating space. The overall structure is very compact and occupies little space.

[0178] The accommodating space is divided into a pre-locking operation area and a locking operation area by an intermediate support frame located at the middle position.

[0179] The input conveyor line 600, the pre-locking positioning module 200 and the pre-locking device 400 are arranged in the pre-locking operation area. The pre-locking positioning module 200 is close to the pre-locking device, which is convenient for the pre-locking device 400 to perform rapid pre-locking operations. Similarly, the output conveyor line 700, the locking positioning module 510 and the locking device 530 are correspondingly arranged in the locking operation area. When locking, the locking device 530 can be quickly moved to the locking positioning module 510 in its corresponding area to perform locking operations.

[0180] Furthermore, since the pre-locking operation area and the locking operation area are separated, it is also possible to avoid mutual interference between the pre-locking device 400 and the locking device 530 during the locking operation.

[0181] In some embodiments of the present application, the pre-locking device 400 includes:

[0182] The pre-locking base 414 is connected to the pre-locking Y-direction moving module 412 at one end and to the pre-locking Z-direction moving module 413 at the other end, and can move in the Y direction or the Z direction under the drive of the two modules;

[0183] The pre-locking base 414 is a pre-locking mounting plate, which includes a first bending portion and a second bending portion.

[0184] When connected, one end is connected to the Y-direction moving module through the first bending portion, and the other end is connected to the Z-direction moving module through the second bending portion.

[0185] When the Y-direction moving module moves in the Y direction, it can drive it to move in the Y direction. Similarly, when the Z-direction moving module moves, it can drive it to move in the up and down directions.

[0186] Two pre-locking mechanisms 421 are provided and arranged vertically side by side;

[0187] There are two Z-axis pre-locking pneumatic modules 422 , which are mounted on the pre-locking base 414 and are respectively connected to the two pre-locking mechanisms 421 to drive the pre-locking mechanisms 421 to move up and down for locking.

[0188] Since the Z-direction pre-locking pneumatic module 422 is connected to the pre-locking mechanism 421 , and the Z-direction pneumatic module is assembled on the pre-locking base 414 , an indirect connection between the pre-locking mechanism 421 and the pre-locking base 414 is achieved.

[0189] The Z-direction pre-locking pneumatic module 422 is connected to the pre-locking mechanism 421 and can be used to drive the pre-locking mechanism 421 to move up and down to perform a locking operation.

[0190] The Z-direction pre-locking pneumatic module 422 uses a pneumatic drive method to control the pre-locking mechanism 421 to move up and down for locking, which can ensure that the pre-locking mechanism 421 moves accurately and ensures that it descends to an accurate locking position.

[0191] The pre-locking Z-direction moving module 413 is a linear moving module, and its moving position range is large, which cannot meet the use requirement of the pre-locking mechanism 421 to move downward within a precise range for locking. The pre-locking Z-direction moving module 413 can be set up to drive the pre-locking mechanism 421 to move within an approximate range in the Z direction, and then the Z-direction pre-locking pneumatic module 422 can be used to accurately control the pre-locking mechanism 421 to move downward precisely for locking.

[0192] The cooperation of the bidirectional Z-direction drive module ensures the accuracy of the locking downward movement distance of the pre-locking mechanism 421 and the precision of the pre-locking.

[0193] In this embodiment, two pre-locking mechanisms 421 are provided to form a double-headed locking module 532 .

[0194] When the movement is driven by the pre-locking X-direction moving module 411, the pre-locking Y-direction moving module 412 and the pre-locking Z-direction moving module 413, the pre-locking base 414 is driven by the pre-locking X-direction moving module 411, the pre-locking Y-direction moving module 412 and the pre-locking Z-direction moving module 413, and the two pre-locking mechanisms 421 assembled thereon are driven to move synchronously in three directions by driving the locking base.

[0195] When pre-locking is performed, each pre-locking mechanism 421 is driven to lock by a Z-direction pre-locking pneumatic module 422 separately configured therein. The two pre-locking mechanisms 421 are arranged side by side and set at a certain distance, so that when the two pre-locking mechanisms 421 are working, they can simultaneously lock screws at two workstations at a certain distance from each other, thereby realizing the pre-locking of two screws at a time and improving the pre-locking efficiency.

[0196] The structure of the locking mechanism is exactly the same as that of the pre-locking mechanism 421, and it is also a double-head locking structure. When locking, the two locking mechanisms can perform locking operations simultaneously, thereby improving the locking efficiency.

[0197] The pre-locking mechanism includes a mounting seat. Two mounting seats are provided, which are respectively used to assemble two Z-direction pre-locking pneumatic modules 422 . The pre-locking mechanism 421 is slidably connected to the mounting seat 423 .

[0198] In some embodiments of the present application, the vertical sliding track formed on the mounting seat 423 and the pre-locking mechanism 421 are connected from top to bottom with: a sliding block 424 , an assembly seat 425 and a fixing seat 426 .

[0199] The sliding block, the assembly seat and the fixing seat are slidably connected to the sliding track to achieve the sliding of the pre-locking mechanism 421 relative to the mounting seat 423 .

[0200] In some embodiments of the present application, the pre-locking mechanism 421 includes:

[0201] The electric screwdriver body 4211 is connected to the sliding block;

[0202] The first adapter seat 4212 is connected to the assembly seat, and its horizontal position relative to the assembly seat is adjustable;

[0203] A transfer shaft is rotatably arranged inside the transfer shaft;

[0204] The first adapter seat 4212 is slidably connected to the assembly seat, and a first threaded hole is provided on the assembly seat. A first adjustment slot is provided on the first adapter seat 4212. A locking screw passes through the first adjustment slot and is locked in the first threaded hole to press the first adapter seat 4212 onto the assembly seat. When adjusting, loosen the locking screw, slide the first adapter seat 4212 to change its position, and tighten the locking screw after sliding into place.

[0205] A universal joint coupling 4213, one end of which is hinged to the electric screwdriver body 4211, and the other end of which is hinged to the transfer shaft;

[0206] The second adapter seat 4214 is connected to the fixing seat, and its water level position relative to the fixing seat is adjustable;

[0207] In some embodiments of the present application, a second threaded hole is provided on the second adapter seat 4214, and a second adjustment slot is provided on the fixed seat. The locking screw passes through the second adjustment slot and is locked and fixed in the second threaded hole. When adjusting, loosen the locking screw, and then slide the second adapter seat 4214. After adjusting into place, tighten the locking screw.

[0208] The nozzle component 4215 is assembled on the second adapter seat 4214;

[0209] An electric screwdriver rod 4216, which can pass through the second adapter seat 4214 and be inserted into the suction nozzle component 4215;

[0210] The quick-change component 4217 has one end connected to the adapter shaft and the other end connected to the electric screwdriver rod 4216.

[0211] The quick-change component 4217 can adopt the existing quick-change joint structure, which can facilitate the replacement of electric screwdriver rods 4216 of different specifications and improve the versatility of the entire equipment.

[0212] Since the first adapter seat 4212 can move horizontally along the assembly seat, the second adapter seat 4214 can also move horizontally along the fixed seat, and the adapter shaft in the first adapter seat 4212 and the electric screwdriver body 4211 are movably connected through the universal joint coupling 4213, the first adapter seat 4212 and the second adapter seat 4214 can be adjusted in position by sliding, thereby adjusting and changing the distance between the two electric screwdriver rods 4216, so that it can adapt to the requirements of screw locking with different spacings.

[0213] The locking mechanism has the same structure as the pre-locking mechanism 421 , and will not be described in detail here.

[0214] In some embodiments of the present application, it also includes:

[0215] The spacing adjustment device 800 is arranged on the locking substrate and connected to the Z-direction pneumatic module of one of the locking mechanisms, and is used to drive the locking mechanism to move so as to adjust the spacing between the two locking mechanisms.

[0216] The spacing adjustment device 800 can drive the Z-direction pneumatic module of one locking mechanism to move, thereby driving the locking mechanism connected to the Z-direction pneumatic module to move relative to the other locking mechanism, thereby achieving position adjustment between the two locking mechanisms.

[0217] By adjusting the position between the two locking mechanisms, the locking function of screws with different spacings can be adapted, thereby improving the versatility of the locking mechanism and expanding the application range of the locking mechanism.

[0218] In some embodiments of the present application, the spacing adjustment device 800 includes:

[0221] and a driven pulley 830 connected to the main pulley member, rotatably connected to the pre-locking base;

[0222] A transmission belt, wound around a main pulley 820 and a driven pulley 830;

[0223] The screw nut mechanism 840 comprises:

[0224] A lead screw component connected to the output shaft of the driven pulley 830;

[0225] The nut component is threadably matched with the lead screw component and is connected to one of the mounting seats.

[0226] When the driven pulley 830 rotates, it drives its output shaft to rotate, the output shaft drives the screw component to rotate, the rotation of the screw component drives the nut component to move linearly, the linear movement of the nut component drives the mounting seat to move linearly, thereby realizing the adjustment of the mounting seat position, driving the position of the locking mechanism assembled above it to move, so as to realize the position adjustment of the two locking mechanisms, so that it can adapt to the screw locking operations of different spacings, thereby improving the versatility of the device.

[0227] In some embodiments of the present application, there are also two screw mounting seats, which are arranged on the locking base.

[0228] Both ends of the lead screw component are rotatably connected in the lead screw mounting seat through bearings, so that the lead screw component can only rotate but cannot move linearly.
