DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Please refer to Figure 1 to Figure 2 The utility model provides a bit selection device, which includes: a selection component 90, the selection component 90 has a matching groove 901, and the shape of at least part of the inner wall surface of the matching groove 901 matches the shape of at least part of the surface of the head of the bit 200; a moving drive component 91, the moving drive component 91 is transmission-connected with the selection component 90, and the moving drive component 91 is used to drive the selection component 90 to move along a first direction so that the bit 200 is inserted into the matching groove 901 or extracted from the matching groove 901; a rotating drive component 92, the rotating drive component 92 is transmission-connected with the selection component 90, and the rotating drive component 92 is used to drive the selection component 90 to rotate, and the selection component 90 drives the bit 200 to rotate around its central axis to adjust the angle of the bit 200.

[0024] The bit selection device with this structural design drives the selection component 90 to move by moving the driving component 91, so that the matching groove 901 of the selection component 90 is plugged into or separated from the head of the bit 200. When the two are plugged, the selection component 90 is driven to rotate by the rotating driving component 92, which can synchronously drive the bit 200 to rotate around its own central axis, thereby adjusting the bit 200 to a required angle, which is convenient for subsequent operation of the bit 200. The bit selection device with this structural design can realize the mechanized selection operation of the bit, that is, adjusting the angle of the bit to a required angle. The angle here refers to the angle of the bit 200 tilted or rotated around its central axis, which solves the technical problem of inconvenient bit selection operation in the related art.

[0025] As described above, after the angle is adjusted, it is more convenient to perform subsequent operations on the screwdriver bit 200, such as press-fitting the screwdriver bit 200 into the sleeve 100. In this process, it is necessary to ensure that the screwdriver bit 200 and the pressing surface of the pressing tool are accurately matched (for example, for a flat screwdriver bit, the matching groove of the pressing tool that matches it is also in a flat shape, and the directions of the two need to be aligned). If the angle of the screwdriver bit 200 is not adjusted in advance, the screwdriver bit 200 and the sleeve 100 cannot be pressed. For another example, after the angle of the screwdriver bit 200 is adjusted, it is more convenient to match with other components, such as with the slot of the packaging box, with the inner hole of the sleeve 100, and so on.

[0026] In this embodiment, the rotation driving component 92 is a servo motor; and / or, the screwdriver bit 200 is inserted into the sleeve 100, and the sleeve 100 is arranged on the bearing component 11, and the screwdriver bit selection device also includes a screwdriver bit detection component 98, so as to detect whether there is a screwdriver bit 200 on the bearing component 11 through the screwdriver bit detection component 98. The rotation driving component 92 adopts a servo motor, so as to more accurately control the rotation angle of the screwdriver bit 200. In this implementation scenario, the screwdriver bit 200 and the sleeve 100 are pre-assembled, that is, the screwdriver bit 200 is inserted into the inner hole of the sleeve 100, and the sleeve 100 is placed on the bearing component 11. Subsequently, it is necessary to perform a pressing operation between the screwdriver bit 200 and the sleeve 100. When pressing, it is necessary to ensure that the pressing tool and the surface of the screwdriver bit 200 are accurately matched, so the screwdriver bit 200 is selected in advance. In this embodiment, the bit direction selection device further includes a bit detection component 98, through which it is possible to detect whether there is a bit 200 on the carrier component 11, thereby avoiding invalid direction selection operations.

[0027] The bit selection device comprises: a bracket 93, a moving driving component 91 is mounted on the bracket 93; a movable seat 94, the moving driving component 91 is connected to the movable seat 94, so as to drive the movable seat 94 to move along the first direction through the moving driving component 91, wherein the rotating driving component 92 is mounted on the movable seat 94. At least part of the transmission structure between the rotating driving component 92 and the selection component 90 is compressibly arranged, when the resistance encountered by the bit 200 during the process of inserting the bit 200 into the matching groove 901 is greater than the preset resistance, the transmission structure is compressed, and the distance between the rotating driving component 92 and the selection component 90 is reduced.

[0028] In this embodiment, the transmission structure between the rotating drive component 92 and the selection component 90 is designed to be a compressible structure, which can play a buffering role in the process of inserting the screwdriver bit 200 into the matching groove 901. When the two are not aligned, the transmission structure is compressed, and then under the rotation of the rotating drive component 92, the two can be smoothly aligned and matched.

[0029] The transmission structure includes: a second compression guide assembly 95, to which the rotation driving component 92 and the selection component 90 are both connected, so as to guide the movement of the selection component 90 relative to the rotation driving component 92 through the second compression guide assembly 95; a second elastic member 96, which is arranged between the rotation driving component 92 and the selection component 90, and when the transmission structure is compressed, the second elastic member 96 undergoes elastic deformation.

[0030] In this embodiment, the transmission structure includes a second compression guide assembly 95 and a second elastic member 96. The second compression guide assembly 95 can guide the movement of the direction selection component 90 along the first direction. The second elastic member 96 can maintain a certain rebound force when compressed. When the bit 200 is aligned with the matching groove 901, the bit 200 can be automatically inserted into the matching groove 901 under the elastic action of the second elastic member 96. Of course, the transmission structure is not limited to the above form, and other structures that can achieve connection and compression are all possible. For example, in another embodiment, the transmission structure is a gas spring, which can be compressed along the first direction and has a certain elasticity.

[0031] The second compression guide assembly 95 includes an outer cylinder and an inner shaft, both of which are extended along the first direction, and the inner shaft is movably inserted into the outer cylinder along the first direction, one of the outer cylinder and the inner shaft is connected to the output shaft of the rotating drive component 92, and the other of the outer cylinder and the inner shaft is connected to the selection component 90.

[0032] A support portion 941 is provided on the movable seat 94, and an avoidance hole extending along the first direction is provided on the support portion 941. The second compression guide assembly 95 is passed through the avoidance hole, wherein the second elastic member 96 is a spring, one end of the spring abuts against the support portion 941, and the other end of the spring abuts against the selection component 90.

[0033] In this embodiment, the bit direction selection device includes a second compression detection component 97, and the second compression detection component 97 is used to detect whether the transmission structure is compressed.

[0034] By designing the second compression detection component 97, it is possible to detect whether the transmission structure is compressed, thereby determining whether the bit 200 and the direction selection component 90 are successfully matched, which is helpful for understanding the working state of the bit selection device and facilitating more accurate control thereof.

[0035] The second compression detection component 97 includes a third sensor 971 and a fourth sensor 972, which are spaced apart along the first direction. When the transmission structure is not compressed, the third sensor 971 is triggered, and when the transmission structure is compressed, the fourth sensor 972 is triggered.

[0036] In this embodiment, two compression detection components work together to detect whether the transmission structure is compressed. This is relatively convenient and the reliability of the detection using two detection components is also relatively high.

[0037] The bit direction selection device includes a controller, and the second compression detection component 97 and the rotation driving component 92 are both electrically connected to the controller. The controller controls the operation of the rotation driving component 92 according to the detection result of the second compression detection component 97.

[0038] In a preferred embodiment, there are multiple direction selection components 90, and the multiple direction selection components 90 are sequentially arranged along the second direction. Correspondingly, there are also multiple mobile drive components 91 and rotation drive components 92, and the multiple mobile drive components 91 are arranged one-to-one with the multiple direction selection components 90, and the multiple rotation drive components 92 are arranged one-to-one with the multiple direction selection components 90. Along the third direction, the direction selection component 90, the mobile drive component 91 and the rotation drive component 92 are all located on one side of the bracket 93. The first direction, the second direction, and the third direction are all different directions. Preferably, the first direction, the second direction, and the third direction are perpendicular to each other.

The bit selection device with this structural design drives the selection component 90 to move by moving the driving component 91, so that the matching groove 901 of the selection component 90 is plugged into or separated from the head of the bit 200. When the two are plugged, the selection component 90 is driven to rotate by the rotating driving component 92, which can synchronously drive the bit 200 to rotate around its own central axis, thereby adjusting the bit 200 to a required angle, which is convenient for subsequent operation of the bit 200.
