[0037] Reference Figures 1 to 6 According to an embodiment of the present application, the material handling fixture includes:

[0038] Positioning plate 100;

[0039] Two clamping plates 200 are provided, and are respectively located on both sides of the positioning plate 100. The lower ends of the clamping plates 200 protrude vertically from the positioning plate 100 and form a clamping portion; an adjustment hole is formed on the side of the clamping plate 200 away from the positioning plate 100, wherein the adjustment hole includes a clamping hole 211 and a loosening hole 212, and the depth of the loosening hole 212 is greater than the depth of the clamping hole 211;

[0040] The swinging member 300 is hinged to the positioning plate 100, and a protrusion 311 is provided on the side of the swinging member 300 close to the two clamping plates 200. The swinging member 300 can rotate relative to the positioning plate 100 to drive the protrusion 311 to engage in the clamping hole 211 or the release hole 212, and the protrusion 311 can abut against the bottom of the clamping hole 211 or the bottom of the release hole 212, so that the clamping plate 200 is close to or away from the positioning plate 100.

[0041] According to the above scheme, since the swinging member 300 is hinged to the positioning plate 100, the swinging member 300 can rotate relative to the positioning plate 100. When the swinging member 300 rotates, the protrusion 311 on the swinging member 300 will rotate accordingly, wherein the clamping hole 211 and the release hole 212 are both located on the rotation path of the protrusion 311. Therefore, when the swinging member 300 rotates, the protrusion 311 can be clamped into the clamping hole 211 or the release hole 212, and abut against the bottom of the clamping hole 211 or the bottom of the release hole 212, that is, when the protrusion 311 is clamped into the clamping hole 211, the two clamping plates 200 are in a state of approaching each other, and when the protrusion 311 is clamped into the release hole 212, the two clamping plates 200 are in a state of moving away from each other.

[0042] It is understood that when it is necessary to transfer parts, at the beginning, refer to Figures 5 and 6 , the protrusion 311 is inserted into the release hole 212, and the two clamping plates 200 are in a state of being away from each other. Then, the clamping plate 200 is moved close to the parts placed in the array so that the parts are between the clamping parts of the two clamping plates 200. Figures 1 to 3 , apply force to the swing member 300 to rotate the swing member 300, so that the protrusion 311 moves from the release hole 212 to the clamping hole 211. Since the depth of the clamping hole 211 is less than the depth of the release hole 212, when the protrusion 311 is clamped into the clamping hole 211, the protrusion 311 pushes the clamping plates 200 closer to each other, and the clamping portion of the clamping plates 200 clamps the part to complete the clamping of the part. After clamping the part, the material removal fixture of the present application is brought close to the cleaning tray, and then, force is applied to the swing member 300 to rotate the swing member 300, so that the protrusion 311 moves from the clamping hole 211 to the release hole 212. Similarly, when the protrusion 311 is clamped into the release hole 212, the clamping plates 200 can move away from each other, so that the product can fall from between the two clamping plates 200.

[0043] It can also be understood that the positioning plate 100 can play an auxiliary limiting role, limiting the distance between the two clamping plates 200 and preventing the clamping plates 200 from getting too close and damaging parts.

[0044] It should be noted that in order to ensure that the protrusion 311 can be switched between the clamping hole 211 and the release hole 212, in this embodiment, the protrusion 311 is a ball plunger. When the protrusion 311 needs to be switched between the clamping hole 211 and the release hole 212, a certain force is applied to the swinging member 300, and the ball head of the ball plunger retracts and slides on the side of the clamping plate. After sliding to the release hole 212 or the clamping hole 211, the ball head pops out and gets stuck in the hole.

[0045] In other embodiments, the protrusion 311 may also be a plastic part, that is, it itself has a certain plasticity. When the protrusion 311 needs to be switched between the clamping hole 211 and the release hole 212, a certain force is applied to the swinging part 300, and the protrusion 311 undergoes plastic deformation to disengage from the clamping hole 211 or the release hole 212, and slide on the side of the clamping plate. After sliding to the release hole 212 or the clamping hole 211, the protrusion 311 returns to its original shape and is stuck in the hole.

[0046] For the specific structure of the swing member 300, refer to Figure 1 and Figure 4 The swing member 300 has a U-shaped structure, that is, the swing member 300 includes an opening portion 310 and a closed portion 320, and the opening portion 310 has two ends. The middle portion of the swing member 300 is hinged to both sides of the positioning plate 100. The two ends of the swing member 300 are respectively located on the side of the two clamping plates 200 away from the positioning plate 100, and the two ends of the swing member 300 are provided with protrusions 311 on the side close to the clamping plates 200. That is, the two ends of the opening portion 310 are respectively located on the side of the two clamping plates 200 away from the positioning plate 100, and the two ends are provided with protrusions 311 on the side close to the clamping plates 200. Therefore, each clamping plate 200 is provided with a set of adjustment holes corresponding to each swing member 300, and the set of adjustment holes is a loosening hole 212 and a clamping hole 211.

[0047] It can be understood that the closed part 320 of the swing member 300 is used to bear force, that is, by applying force to the closed part 320, the swing member 300 swings, and the two ends of the opening part 310 swing, so that the protrusion 311 on the end moves and converts between the clamping hole 211 and the release hole 212.

[0048] In addition, it should be noted that, in order to ensure the stability of the clamping plates 200 when they are close to each other, in this embodiment, Figure 1 and Figure 4 There are two swinging members 300 , and the two swinging members 300 are respectively arranged at both ends of the positioning plate 100 , and a group of adjustment holes are respectively provided at both ends of each positioning plate 100 corresponding to the swinging members 300 .

[0049] It can be understood that, corresponding to the two swinging members 300, a group of adjustment holes are provided at both ends of each positioning plate 100. When parts need to be clamped, force is applied to the swinging members 300 at the same time, so that the protrusions 311 on the two swinging members 300 simultaneously push the clamping plates 200 closer to each other, thereby improving the stability of the clamping plates 200 during movement.

[0050] To limit the rotation angle of the swing member 300, refer to Figure 1 and Figure 4 The material picking fixture of the present application also includes a limit member 400, which is arranged on the rotation path of the swing member 300. When the protrusion 311 is inserted into the clamping hole 211 or the release hole 212, the swing member 300 abuts against the limit member 400.

[0051] It is understandable that after the protrusion 311 is inserted into the clamping hole 211 or the release hole 212 , the swing member 300 cannot continue to rotate, ensuring that the protrusion 311 can be inserted into the clamping hole 211 or the release hole 212 .

[0052] For the specific matching form of the limiting member 400 and the swing member 300, refer to Figure 2 and Figure 5 The limiting member 400 is formed with a first limiting surface 410 and a second limiting surface 420, and an angle is formed between the first limiting surface 410 and the second limiting surface 420. Corresponding to the first limiting surface 410 and the second limiting surface 420, the swinging member 300 is formed with a first abutting surface 330 and a second abutting surface 340, wherein, when the protrusion 311 is inserted into the clamping hole 211, the swinging member 300 abuts against the first limiting surface 410 of the limiting member 400 through the first abutting surface 330; when the protrusion 311 is inserted into the release hole 212, the swinging member 300 abuts against the second limiting surface 420 of the limiting member 400 through the second abutting surface 340.

[0053] In addition, it should be noted that one end of a swinging member 300 is provided corresponding to one limiting member 400 .

[0054] To ensure that the two clamping plates 200 are away from each other when the protrusion 311 moves from the clamping hole 211 to the loosening hole 212, in this embodiment, referring to Figure 2 and Figure 5 An elastic member 500 is provided between the positioning plate 100 and the clamping plate 200 .

[0055] It can be understood that since the depth of the release hole 212 is shallower than the depth of the clamping hole 211, when the protrusion 311 is inserted into the release hole 212, the protrusion 311 cannot be lowered to the bottom of the release hole 212. Therefore, under the elastic force of the elastic member 500, when the protrusion 311 is inserted into the release hole 212, the elastic member 500 will push the clamping plate 200 away from the positioning plate 100, and the clamping plate 200 will approach the protrusion 311 and keep the protrusion 311 against the bottom of the release hole 212, so that the two clamping plates 200 will move away from each other.

[0056] In other embodiments, a cylinder may be provided between the positioning plate 100 and the clamping plate 200, or a cylinder or elastic member 500 may be provided between the two clamping plates 200, or the clamping plates 200 may be moved away from each other manually or by a robot.

[0057] It should be noted that, since the clamping plate 200 needs to be hinged with the swing member 300 and clamp parts, in order to ensure the rigidity of the connection between the clamping plate 200 and the swing member 300 and to avoid the clamping plate 200 from clamping parts, in this embodiment, the clamping plate 200 is hinged with the swing member 300 and clamps the parts. Figure 1 and Figure 4 The clamping plate 200 includes an outer plate 210 and an inner plate 220. The outer plate 210 is set to a metal material, and the inner plate 220 is set to a plastic material. The outer plate 210 and the inner plate 220 are fixedly connected. The inner plate 220 is arranged on the side of the outer plate 210 close to the positioning plate 100. The inner plate 220 constitutes a clamping portion, and the outer plate 210 forms an adjustment hole, that is, the inner plate 220 is arranged between the outer plate 210 and the positioning plate 100.

[0058] It is understood that the hinged connection between the metal outer plate 210 and the swing member 300 and the formation of the adjustment hole that cooperates with the protrusion 311 can make the outer plate 210 less susceptible to damage and scratches by the protrusion 311. The plastic inner plate 220 clamps the parts to avoid rigid collision with the parts and thus prevent damage to the parts.

[0059] For better gripping of parts, refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 The lower end of the positioning plate 100 forms a fixed groove 110 . It should be noted that the shape of the fixed groove 110 corresponds to the outer contour of the part, and a notch 111 is formed at the position of the fixed groove 110 close to the clamping plate 200 .

[0060] It is understandable that when the clamping jig of the present application approaches the part, the part will enter the fixed groove body 110, and the two ends of the part close to the clamping plate 200 will be exposed through the notch 111. When the clamping plates 200 are close to each other, the clamping plates 200 abut the exposed part of the part and clamp the fixed part. In summary, the fixed groove body 110 can play a role in assisting in fixing the part and has a limiting effect on the part. In the process of the clamping plate 200 clamping the part for transportation, the part is not easy to slide or fall. In addition, it should be noted that the fixed groove body 110 includes multiple ones, and is distributed along the length direction of the positioning plate 100, so that the clamping jig of the present application can clamp multiple parts at the same time.

[0061] In order to ensure the accuracy of the material removal fixture in the present application in placing the parts on the cleaning tray, a positioning column (not shown in the figure) is provided at the lower end of the positioning plate 100, and correspondingly, a positioning hole is provided on the cleaning tray.

[0062] It is understandable that when the material picking fixture needs to place the parts it clamps on the cleaning tray, the positioning column of the positioning plate 100 is inserted into the positioning hole of the cleaning tray, and then the swing member 300 is rotated to make the clamping plate 200 release the parts so that the parts fall accurately onto the cleaning tray.

[0063] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
