Description

Technical Field

[0001] The 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 processing of the camera, 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 use requirements, the screw bits on the air-blowing automatic screw locking machine are used in a longer length. The longer screw bits can more easily reach some deeper or more difficult-to-reach positions. The longer screw bits 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 connecting part of the screw 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

During the movement, through the connection of the elastic component, the ball 902 on the front side of the support plate 802 is pressed against the outside of the screwdriver bit 105.

[0052] Preferably, the extrusion assembly includes an annular pressing plate 1101 which is sleeved on the outside of the screwdriver head 105 and is used to abut against the upper end of the push rod 1005. The annular pressing 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 restrained and limited. During the movement, the annular pressure plate 1101 is driven by the L-shaped plate 1102 to resist 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.

[0054] Preferably, the guide assembly includes a plurality of first sleeves 1301 fixed inside the annular cover 7, 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;

[0059] It should be noted here that: after the ball 902 on one side of the support plate 802 abuts against the outer side of the screwdriver bit 105, the screwdriver bit 105 exerts 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 contract toward the support plate 802. During the movement, each group of third sliding bars 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 abut against the outer side of the screwdriver bit 105 with a greater force, thereby ensuring the support effect on the screwdriver bit 105.

[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 scheme: 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 conveyed screws are positioned through the two groups of semicircular positioning holes. After the screws are fed and positioned, the mounting seat 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 action of the first telescopic component. Through the downward movement of the feeding head 103, the front end of the screw delivered and positioned on the feeding head 103 is in the correct position of the screw hole in the locking and fixing position. The connecting seat 3 is above the upper part, and in the process of the connection seat 3 descending, the connecting seat 3 is abutted against the limit block 207, and the descent of the connecting seat 3 and the feed head 103 is limited by abutment. As the mounting seat 101 continues to be driven downward, the screwdriver head 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 and forced to move downward to the feed head 103 through the rotation effect of the electric screwdriver body 102 on the screwdriver head 105 and the continued downward movement of the screwdriver head 105. In the process of the screw movement In the process, the two groups of L-shaped positioning plates 602 are driven to rotate away from each other by the counteraction between the ends of the screws and the inner wall of the conical surface 603, so that the screws are pushed out from the feed head 103. In the process of pushing out, the screws are connected with the screw holes at the locking and fixing positions by the rotating action of the screwdriver bit 105. With the continued rotation and pushing action of the screwdriver bit 105 on the screws, the screws are screwed into the inside of the screw holes, and the locking and fixing operation of the screws is completed. The whole locking and fixing process has a high degree of automation, making the locking and fixing of the screws more intelligent.

[0070] As the screwdriver bit 105 continuously pushes and rotates the screw, the electric screwdriver body 102 continuously moves toward the connection seat 3 that is restrained and limited. During the movement, the annular pressure plate 1101 is driven by the L-shaped plate 1102 to resist 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 bit 105. During the movement, the ball 90 on the front side of the support plate 802 is connected by the elastic component. 2 is against the outer side of the screwdriver bit 105, and the outer side of the screwdriver bit 105 is supported by the abutment between the ball 902 and the outer side of the screwdriver bit 105. The support prevents the screwdriver bit 105 from swinging when pushing and rotating the screw, so that the screwdriver bit 105 can stably screw the screw in and push it, reducing the probability of an inclination angle between the screw and the screw hole, further ensuring the quality of screw locking and fixing, and in the whole supporting process, the screwdriver bit 105 is not supported before the screwdriver bit 105 is abutted and connected, so that the screwdriver bit 105 can be slightly offset and swung when it is abutted and connected with the screw, so that the screwdriver 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 through the rotating assembly. In the process of the rotation of the annular cleaning cover 1501, the exhaust fan 1503 exhausts air inside the annular cleaning cover 1501 and the communication function of each group of air holes 1502 is used to extract and press the outer side of the screwdriver bit 105. Through the extraction and pressing effect, foreign matter adsorbed on the outer surface of the screwdriver bit 105 is sucked into the inner part 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.
