Abstract

The present invention discloses an intelligent electric screwdriver three-axis screw locking device, which relates to the field of camera processing technology. The intelligent electric screwdriver three-axis screw locking device includes an air-blowing automatic screw locking machine for intelligently locking screws. The present invention enables the screw to be screwed into the interior of the screw hole through the mutual cooperation of components such as a three-axis control component, a discharge component, a positioning component, and a support component. During the locking and fixing process, the support effect prevents the screwdriver bit from swinging when pushing and rotating the screw, so that the screwdriver bit can stably screw in and push the screw, reducing the probability of an inclination angle between the screw and the screw hole, further ensuring the quality of screw locking and fixing. In the entire supporting process, the screwdriver bit is not supported before it is abutted against the screw, so that the screwdriver bit can be slightly offset and swung when it is abutted against the screw, making it easier for the screwdriver bit to align more freely with the screw head.

Description

Technical Field

[0001] The present invention relates to the technical field of camera processing, and in particular to an intelligent electric screwdriver three-axis screw locking device. Background Art

[0002] During the camera processing process, some connecting parts need to be limited by screw locking and tightening after splicing. In order to facilitate the intelligent and efficient locking and fixing of the screws, an air-blowing automatic screw locking machine is often used to lock and tighten the screws after delivery.

[0003] The air-blowing automatic screw locking machine is in use. According to the needs of use, the screw bit on the air-blowing automatic screw locking machine is longer in length. The longer screw bit can more easily reach some deeper or difficult-to-reach positions. The longer screw bit can cross other components and directly reach the screw hole position for locking operations without the need for complicated disassembly or adjustment of the product. This makes the screw locking machine more adaptable when facing products of various shapes and structures, and can complete the screw locking task in a more complex spatial environment. However, in the process of rotating and locking the screw with a longer screw bit, if there is a gap between the screw bit and the screw connection part or the connection is not firm enough, the screw bit is prone to swing during high-speed rotation. In the process of tightening the screw, the swing of the screw bit may cause the screw to be screwed into the screw hole at a certain tilt angle, so that the screw cannot completely fit the inner wall of the screw hole, affecting the quality of screw locking and fixation. For this reason, we propose an intelligent electric screwdriver three-axis screw locking device. Summary of the 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 making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] See also Figures 1-14 The figure shows an intelligent electric screwdriver three-axis screw locking device, including an air-blowing automatic screw locking machine for intelligently locking screws.

[0040] It should be noted here that: the interior of the electric screwdriver body 102 is provided with a rotating member for rotating the screwdriver head 105, and the feeder is responsible for distributing the screws one by one to the locking position. It usually adopts a mechanical structure or a pneumatic method to ensure that only one screw is fed out at a time. The electric screwdriver body 102 and the feeder are conventional operating components in the technical field of air-blowing automatic screw locking machines. In this application, as prior art, their working method and principle will not be further described.

[0041] The machine also includes: a three-axis control component for controlling the multi-angle movement of the air-blowing automatic screw locking machine; a connecting seat 3 is provided between the feed head 103 and the mounting seat 101; a first telescopic component for telescopically connecting the feed head 103 is provided between the connecting seat 3 and the mounting seat 101; a positioning component for assisting in screw delivery and positioning, and a discharging component for assisting in discharging after positioning are provided on the feed head 103;

[0042] The discharge assembly includes a mounting hole 501 formed on the connecting base 3, a mounting tube 502 being fixed inside the mounting hole 501, one end of the mounting tube 502 being fixed to the upper end of the feed head 103, a discharge hole 503 being provided inside the feed head 103, the feed tube 104 and the mounting tube 502 being communicated with the interior of the discharge hole 503, an annular cover 7 being fixed to the mounting tube 502, a support assembly for supporting the screwdriver bit 105 being provided inside the annular cover 7, and a cleaning assembly for cleaning the outside of the screwdriver bit 105 being provided at the upper end of the mounting tube 502;

[0043] It should be noted here that: through the mutual cooperation of the three-axis control component, the discharge component, the positioning component and the support component, the screw is screwed into the inside of the screw hole to complete the locking and fixing operation of the screw. The entire locking and fixing process is highly automated, making the locking and fixing of the screw more intelligent. In the locking and fixing process, the support effect is used to prevent the screw head 105 from swinging when pushing and rotating the screw, so that the screw head 105 can stably screw in and push the screw, reducing the probability of an inclination angle between the screw and the screw hole, further ensuring the quality of the screw locking and fixing, and in the entire supporting process, the screw head 105 is not supported before it is abutted against the screw, so that the screw head 105 can be slightly offset and swung when it is abutted against the screw, making it easier for the screw head 105 to align more freely with the screw head.

[0044] Preferably, the positioning assembly includes two sets of L-shaped positioning plates 602, and the two sets of L-shaped positioning plates 602 are rotatably connected to the feed head 103 through the torsion shaft 601. The two sets of L-shaped positioning plates 602 are provided with semicircular positioning holes for positioning the screws after outflow, and the upper ends of the two sets of semicircular positioning holes are provided with conical surfaces 603 for abutting against the ends of the screws for transmission;

[0045] It should be noted here that the screws entering the feed head 103 pass through the discharge hole 503 and fall between the two groups of semicircular positioning holes of the L-shaped positioning plates 602, and the screws after delivery are positioned by the two groups of semicircular positioning holes.

[0046] Multiple groups of support assemblies are provided, and the multiple groups of support assemblies are arranged in a state of an annular array inside the annular cover 7. The support assembly includes a mounting plate 801 arranged inside the annular cover 7, a support plate 802 is provided on one side of the mounting plate 801, and the mounting plate 801 and the support plate 802 are connected by an elastic component. A rolling assembly for facilitating the rotation of the bit 105 during the support process of the bit 105 is provided on one side of the support plate 802. A transmission assembly for transmitting the mounting plate 801 and a guide assembly for guiding during the transmission process are provided on the annular cover 7;

[0047] It should be noted here that: through transmission, the ball 902 on the front side of the support plate 802 is abutted against the outer side of the bit 105. The abutment between the ball 902 and the outer side of the bit 105 supports the outer side of the bit 105. The support prevents the bit 105 from swinging when pushing and turning the screw.

[0048] The rolling assembly includes a spherical groove 901 formed on one side of the support plate 802. A ball 902 is rotatably connected to the interior of the spherical groove 901 for supporting against the outer side of the screwdriver bit 105.

[0049] It should be noted that after the ball 902 abuts against the outer side of the bit 105 , the rotatable connection of the ball 902 inside the spherical groove 901 can maintain support for the bit 105 without affecting its rotation.

[0050] The transmission assembly includes a transmission plate 1001 arranged inside the annular cover 7, a second telescopic assembly for telescopically connecting the transmission plate 1001 is provided inside the annular cover 7, a fixed plate 1002 is provided on one side of the mounting plate 801, an oblique groove 1003 is provided on the transmission plate 1001, a transmission pin 1004 is slidably connected to the oblique groove 1003, one end of the transmission pin 1004 is fixed to the fixed plate 1002, a push rod 1005 is slidably connected to the connecting seat 3 and the annular cover 7, one end of the push rod 1005 is fixed to the transmission plate 1001, and an extrusion assembly for extruding the push rod 1005 is provided below the electric batch body 102;

[0051] It should be noted here that: through the extrusion component, the transmission plate 1001 is pushed to move downward inside the annular cover 7. During the movement of the transmission plate 1001, the interaction between the inclined groove 1003 and the transmission pin 1004 drives the fixed plate 1002 and the mounting plate 801 to move toward the outside of the screwdriver bit 105. During the movement, the connecting action of the elastic component causes the ball 902 on the front side of the support plate 802 to be pressed against the outside of the screwdriver bit 105.

[0052] Preferably, the extrusion assembly includes an annular pressure plate 1101 sleeved on the outside of the screwdriver head 105 and used to abut against the upper end of the push rod 1005. The annular pressure plate 1101 is connected and fixed to the lower end of the electric screwdriver body 102 by multiple groups of L-shaped plates 1102.

[0053] It should be noted here that: as the screwdriver head 105 continuously pushes and rotates the screw, the electric screwdriver body 102 continuously moves toward the connecting seat 3 that is limited by the offset. During the movement, the L-shaped plate 1102 drives the annular pressure plate 1101 to offset the upper end of the push rod 1005 and pushes the transmission plate 1001 at one end of the push rod 1005 to move downward inside the annular cover 7 under force.

[0054] Preferably, the guide assembly includes a plurality of first sleeves 1301 fixed inside the annular cover 7, and a first slide bar 1302 is slidably connected to the first sleeve 1301, and one end of the first slide bar 1302 is fixed to the mounting plate 801;

[0055] It should be noted here that the movement of the mounting plate 801 after being subjected to force is guided by the first sleeve 1301 and the first slide bar 1302 .

[0056] Preferably, the second telescopic assembly includes a rectangular plate 1401 fixed to the lower end of the transmission plate 1001, a plurality of second sleeves 1402 are fixed to the rectangular plate 1401, a second slide rod 1403 is slidably connected to the second sleeve 1402, one end of the second slide rod 1403 is fixed to the inside of the annular cover 7, and a mounting spring 1404 is sleeved on the outside of the second sleeve 1402;

[0057] It should be noted here that: through each group of second sleeves 1402 and second slide rods 1403, the rectangular plate 1401 and the transmission plate 1001 are guided to extend and retract after being subjected to force, and by installing springs 1404, the rectangular plate 1401 and the transmission plate 1001 are easily reset after the contraction movement.

[0058] Preferably, the elastic component includes multiple groups of third sleeves 1201 fixed to one side of the mounting plate 801, and a third sliding rod 1202 is slidably connected to the third sleeve 1201. One end of the third sliding rod 1202 is fixed to one side of the support plate 802, and an extrusion spring 1203 is sleeved on the outer side of each group of third sleeves 1201;

[0059] It should be noted here that: after the ball 902 on one side of the support plate 802 is against the outer side of the screwdriver bit 105, the screwdriver bit 105 has a limiting effect on the ball 902 and the support plate 802 and as the mounting plate 801 continues to move, the mounting plate 801 is forced to move toward the support plate 802 for contraction. During the movement, each group of third sliding rods 1202 is pushed to slide on each group of third sleeves 1201 respectively, and the extrusion spring 1203 is deformed under force to generate elastic force. Through the elastic force of the extrusion spring 1203, the ball 902 on the support plate 802 is pushed to counteract the outer side of the screwdriver bit 105 with a greater force, thereby ensuring the support effect of the screwdriver bit 105.

[0060] Preferably, the cleaning assembly includes an annular cleaning cover 1501 rotatably connected to the upper end of the mounting tube 502, a plurality of air holes 1502 for feeding materials during the cleaning process are provided on the inner side of the annular cleaning cover 1501, an exhaust fan 1503 for extracting the pressure inside the annular cleaning cover 1501 is installed on the upper end of the annular cleaning cover 1501, and a rotating assembly for rotating the annular cleaning cover 1501 is provided on the connecting base 3;

[0061] It should be noted here that: the annular cleaning cover 1501 is driven to rotate by the rotating component. During the rotation of the annular cleaning cover 1501, the exhaust fan 1503 exhausts air inside the annular cleaning cover 1501 and the communication effect of each group of air holes 1502, so as to extract and press the outer side of the screwdriver bit 105 passing through. Through the extraction and pressure effect, foreign matter adsorbed on the outer surface of the screwdriver bit 105 is sucked into the interior of the annular cleaning cover 1501 through the air holes 1502 for collection, thereby ensuring the cleanliness of the outer surface of the screwdriver bit 105 and further facilitating the high-quality locking and fixing operation of the screwdriver bit 105.

[0062] Preferably, the rotating assembly includes a ring gear 1601 fixed to the outside of the annular cleaning cover 1501, an L-shaped frame 1602 is fixed to the connecting seat 3, a mounting shaft 1603 is rotatably connected to the L-shaped frame 1602, a gear 1604 is fixed to the mounting shaft 1603, the gear 1604 and the ring gear 1601 are meshed with each other, and a driving motor 1605 for driving the mounting shaft 1603 is installed on the L-shaped frame 1602;

[0063] It should be noted here that: the gear 1604 on the mounting shaft 1603 is driven to rotate by the driving motor 1605. During the rotation of the gear 1604, the annular cleaning cover 1501 is driven to rotate through the mutual engagement transmission between the gear 1604 and the ring gear 1601.

[0064] Preferably, the first telescopic assembly includes a plurality of groups of T-shaped rods 401 slidably connected to the mounting base 101, one end of each group of T-shaped rods 401 is fixed to the connecting base 3, and a connecting spring 402 is sleeved on the outer side of each group of T-shaped rods 401;

[0065] It should be noted that the T-shaped rod 401 and the connecting spring 402 facilitate the telescopic connection between the connecting seat 3 and the mounting seat 101 and the reset after the telescopic movement.

[0066] Preferably, the three-axis control assembly includes a mounting platform 201, a first slide 202 is slidably connected to the mounting platform 201 via a slide rail, a first cylinder 203 for driving the first slide 202 is installed on the mounting platform 201, a second slide 204 is slidably connected to the first slide 202 via a slide rail, a second cylinder 205 for driving the second slide 204 is installed on the first slide 202, the mounting seat 101 is slidably connected to the second slide 204 via a slide rail, a third cylinder 206 for driving the mounting seat 101 is installed on the second slide 204, and a limit block 207 for abutting against the descending connecting seat 3 is fixed to the lower end of the second slide 204;

[0067] It should be noted here that: through the driving action of the first cylinder 203 on the first slide 202, the driving action of the second cylinder 205 on the second slide 204 and the driving action of the third cylinder 206 on the mounting base 101, the mounting base 101 can be conveniently moved in the three-axis directions of horizontal, longitudinal and vertical directions. Through the movement of the position, it is convenient to perform screw locking and fixing operations at different positions.

[0068] In this solution: an intelligent electric screwdriver three-axis screw locking device includes the following steps:

[0069] During the processing of the camera, when the air-blowing automatic screw locking machine is used to lock and fix the screws at the corresponding positions, the screws to be used are conveyed to the inside of the feed head 103 through the feed pipe 104 through the feeding function of the external feeder and the connecting and conveying function of the air pipe. The screws entering the feed head 103 pass through the discharge hole 503 and fall between the semicircular positioning holes of the two groups of L-shaped positioning plates 602. The screws after conveyance are positioned through the two groups of semicircular positioning holes. After the screws are fed and positioned, the mounting base 101 is adjusted by the three-axis control component. The feeding head 103 below the mounting seat 101 is moved to the designated position where the screw needs to be locked and fixed. After the movement is completed, the mounting seat 101 and the electric screwdriver body 102 on the mounting seat 101 are driven to move downward by the third cylinder 206. During the downward movement of the mounting seat 101, the connecting seat 3 and the feeding head 103 below the connecting seat 3 are driven to move downward by the connection effect of the first telescopic component. The downward movement of the feeding head 103 makes the front end of the screw after the positioning on the feeding head 103 be in the positive position of the screw hole in the locking and fixing position. Above, and in the process of the connecting seat 3 descending movement, the connecting seat 3 is abutted against the limit block 207, and the descent of the connecting seat 3 and the feeding head 103 is limited. As the mounting seat 101 continues to be driven downward, the screw bit 105 on the electric screwdriver body 102 passes through the mounting tube 502 and is abutted against the upper end of the positioned screw. After the abutment connection, the screw is rotated by the electric screwdriver body 102 on the screw bit 105 and the screw bit 105 continues to descend, so that the screw is rotated and forced to move downward to the feeding head 103. In the process of the screw movement In the process, the two sets of L-shaped positioning plates 602 are driven to rotate away from each other by the counteraction between the end of the screw and the inner wall of the tapered surface 603, so that the screw is pushed out from the feed head 103. During the pushing process, the screw is connected to the screw hole at the locking and fixing position by the rotation of the screw bit 105. With the continued rotation and pushing action of the screw bit 105 on the screw, the screw is screwed into the inside of the screw hole, completing the locking and fixing operation of the screw. The whole locking and fixing process has a high degree of automation, making the locking and fixing of the screw more intelligent.

[0070] As the screwdriver head 105 continuously pushes and rotates the screw, the electric screwdriver body 102 continuously moves toward the connection seat 3 that is limited by the offset. During the movement, the annular pressure plate 1101 is driven by the L-shaped plate 1102 to offset the upper end of the push rod 1005 and push the transmission plate 1001 at one end of the push rod 1005 to move downward inside the annular cover 7. During the movement of the transmission plate 1001, the interaction between the inclined groove 1003 and the transmission pin 1004 drives the fixing plate 1002 and the mounting plate 801 to move toward the outside of the screwdriver head 105. During the movement, the ball 90 on the front side of the support plate 802 is connected by the elastic component. 2. The outer side of the bit 105 is abutted against the outer side of the bit 105 by the abutting effect of the ball 902 and the outer side of the bit 105, so as to support the outer side of the bit 105. The supporting effect prevents the bit 105 from swinging when pushing and rotating the screw, so that the bit 105 can stably screw the screw into the screw, reduce the probability of an inclination angle between the screw and the screw hole, and further ensure the quality of the screw locking and fixing. In the whole supporting process, the bit 105 is not supported before the bit 105 is abutted against the screw, so that the bit 105 can be slightly offset and swung when it is abutted against the screw, so that the bit 105 can be more freely aligned with the screw head.

[0071] In the process of passing the screwdriver bit 105 through the mounting tube 502, the annular cleaning cover 1501 is driven to rotate by the rotating assembly. During the rotation of the annular cleaning cover 1501, the exhaust fan 1503 exhausts air inside the annular cleaning cover 1501 and the communication effect of each group of air holes 1502 is used to extract and press the outside of the screwdriver bit 105. Through the extraction and pressure action, foreign matter adsorbed on the outer surface of the screwdriver bit 105 is sucked into the interior of the annular cleaning cover 1501 through the air holes 1502 for collection, thereby ensuring the cleanliness of the outer surface of the screwdriver bit 105 and further facilitating the high-quality locking and fixing operation of the screwdriver bit 105.
