Compared with the traditional magnetic suction method, the present invention can keep the screw vertical during the screw straightening process, thereby facilitating the existing automatic screw locking device to absorb the screw.

[0037] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] Example 1

[0041] Please refer to Figure 1-Figure 4 A combined screw feeding and straightening device comprises a support frame 1, a first limiting portion is arranged on the top of the support frame 1, a mounting plate 4 is installed on one side of the support frame 1, a driving member is arranged on the mounting plate 4, and the driving member is connected to a second limiting portion. The second limiting portion cooperates with the first limiting portion under the drive of the driving member to clamp and straighten the screw. Compared with the traditional magnetic suction method, the present application can keep the screw vertical during the screw straightening process, thereby facilitating the existing automatic screw locking device to absorb the screw.

[0042] Further, such as Figure 1-Figure 2 As shown, the first limiting portion includes a fixing seat 2 installed on the top of the support frame 1, a fixing plate 201 is fixedly installed on one side of the fixing seat 2, a third arc groove 202 is arranged on the side of the fixing plate 201 away from the fixing seat 2, and a groove 203 is opened at the bottom of the fixing seat 2, the fixing seat 2 is used to support the fixing plate 201, and the setting of the third arc groove 202 can adapt to various different screw straightening.

Specifically, Figure 1-Figure 3 As shown, the second limiting portion includes a first righting pull plate 501 connected to the telescopic rod of the cylinder 5, and the outer surface of the first righting pull plate 501 is plugged into the groove 203. The first righting pull plate 501 can be limited by the groove 203, thereby improving the stability of the movement of the first righting pull plate 501.

[0045] Further, such as Figure 1 and Figure 3 As shown, the first straightening pull plate 501 is provided with a first arc groove 502 and two first slopes 503 respectively located on both sides of the first arc groove 502 at one end thereof close to the third arc groove 202. The first slope 503 is provided to facilitate the screw to enter the first arc groove 502, and the diameter of the first arc groove 502 is selected to be compatible with the screw to be straightened. When the screw enters between the first arc groove 502 and the third arc groove 202, it can remain vertical under the limit of the first arc groove 502, and the screw is clamped and straightened.

[0046] The use process of the combined screw feeding and straightening device provided by the utility model is as follows:

[0047] Reference Figure 8 , Figure 8 The number at A is the screw of the existing screw feeder, and B is the combination screw required for straightening. When the screw disk rotates and drives the screw to reach between the third arc groove 202 and the first arc groove 502, the cylinder 5 drives the first straightening pull plate 501 to move. During the movement of the first straightening pull plate 501, the first arc groove 502 approaches the third arc groove 202, and the combination screw is clamped by the first straightening pull plate 501 and the fixed plate 201. Then the existing automatic screw locking device absorbs the combination screw, and then the cylinder 5 drives the first straightening pull plate 501 to move so that the first arc groove 502 is away from the third arc groove 202 to loosen the screw.

[0048] Example 3

[0049] The combined screw feeding and straightening device provided in Example 1 is further optimized. Specifically, Figure 4-Figure 5As shown, the second limiting portion includes a second righting pull plate 6 connected to the telescopic rod of the cylinder 5, a chamber 601 is opened in the second righting pull plate 6, a first connecting plate 602 is inserted into the chamber 601, one end of the first connecting plate 602 passes through the chamber 601 and is fixedly connected to the second connecting plate 603, the first connecting plate 602 is used to connect the second connecting plate 603 and the second righting pull plate 6, so that the second connecting plate 603 and the second righting pull plate 6 can move relative to each other, thereby reducing the damage to the screws when clamping the screws.

[0050] Further, such as Figure 5 As shown, one end of the first connecting plate 602 away from the second connecting plate 603 is fixedly connected to a buffer spring 604, and one end of the buffer spring 604 away from the first connecting plate 602 is fixedly connected to the inner wall of the chamber 601. The force of the buffer spring 604 can pull the second connecting plate 603 closer to the second straightening pull plate 6 through the first connecting plate 602.

[0051] Further, such as Figure 4 and Figure 6 As shown, a slot 605 is provided in the second connecting plate 603 , a plug plate 609 is inserted into the slot 605 , a clamp seat 610 is fixedly installed on the top of the plug plate 609 , and the plug plate 609 and the second connecting plate 603 cooperate with each other to support the clamp seat 610 .

[0052] Further, such as Figure 6 As shown, a second arc groove 612 and two second slopes 611 respectively located on both sides of the second arc groove 612 are provided at one end of the clamp seat 610 close to the third arc groove 202. The second slopes 611 are arranged to facilitate the screw to enter the second arc groove 612, and the diameter of the second arc groove 612 is selected to be compatible with the screw to be straightened. When the screw enters between the second arc groove 612 and the third arc groove 202, it can remain vertical under the limit of the second arc groove 612, and the screw is clamped and straightened.

[0053] Further, such as Figure 7 As shown, two blocking bars 606 are fixedly installed on the inner walls on both sides of the slot 605 , and the blocking bars 606 are in contact with the side surfaces of the plug board 609 . The blocking bars 606 are used to limit the plug board 609 to prevent the plug board 609 from moving horizontally in the slot 605 .

[0054] Further, such as Figure 6-Figure 7As shown, elastic sheets 607 are fixedly installed on the inner walls on both sides of the slot 605, and the tops of the two elastic sheets 607 are fixedly connected with clamping plates 608. The sides of the two clamping plates 608 that are close to each other are in contact with the two sides of the plug plate 609 respectively. Slopes are provided on both sides of the bottom of the plug plate 609. The setting of the slope facilitates the insertion of the plug plate 609 between the two clamping plates 608. The elastic sheet 607 can be made of spring steel. The elastic sheet 607 can clamp the plug plate 609 through the clamping plates 608, and then fix the clamp seat 610. After the clamp seat 610 is pulled upward to separate the plug plate 609 from the slot 605, the clamp seat 610 can be replaced, and then the clamp seat 610 with a second arc groove 612 of corresponding size can be replaced according to the diameter of the screw.

[0055] The use process of the combined screw feeding and straightening device provided by the utility model is as follows:

[0056] Reference Figure 8 , Figure 8 The number at A is the screw of the existing screw feeder, and B is the combination screw required for straightening. When the screw disk rotates and drives the screw to reach between the third arc groove 202 and the first arc groove 502, the cylinder 5 drives the second straightening pull plate 6 to move. During the movement of the second straightening pull plate 6, the second arc groove 612 approaches the third arc groove 202, and the combination screw is clamped by the second straightening pull plate 6 and the fixed plate 201. Then the existing automatic screw locking device absorbs the combination screw, and then the cylinder 5 drives the second straightening pull plate 6 to move so that the second arc groove 612 is away from the third arc groove 202 to loosen the screw.
