Description

Technical Field

[0001] The invention relates to the field of non-standard automatic assembly, and in particular to a feeding device for a clamp body. Background Art

[0002] In the field of non-standard automation, it is well known to use a feeding device to achieve automation when transferring the clamp body. The inventors have found that the existing feeding device has at least the following problems during the feeding process:

[0003] Firstly, since the shape and structure of the pliers body itself is relatively complex and its surface is often an arc-shaped surface, the pliers body is prone to shaking during the transmission of the pliers body by a general feeding device due to the small contact area between the pliers body surface and the conveyor belt on the feeding device, making it difficult to control the position of the pliers body, making it difficult for the subsequent grasping mechanism to accurately grasp the pliers body, resulting in low feeding efficiency.

[0004] In view of this, it is necessary to develop a feeding device for a clamp body to solve the above problems. Summary of the invention

[0005] In view of the shortcomings in the prior art, the main purpose of the present invention is to provide a feeding device for a pliers body, which limits the movement of the pliers body by a blocking part and uses a correction part to push the pliers body to rotate, thereby adjusting the position of the pliers body so that the clamping assembly can accurately grasp the pliers body and improve the feeding efficiency.

[0019] Preferably, the shape of the end face of the correction end corresponds to the side face of the raised portion, so that the push rod pushes the workpiece to rotate until the end face of the correction end is in contact with the side face of the raised portion.

[0020] Preferably, the loading station includes a limiting portion, and the workpiece moves to abut against the limiting portion, thereby limiting the movement of the workpiece;

[0021] The gripping assembly includes a gripping portion for gripping a workpiece;

[0022] The workpiece includes a pliers body and a hook extending outward from one end of the pliers body, and a shoulder with an arc-shaped surface is formed at a portion where the hook is integrated with the pliers body;

[0075] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown in the figure, it can be seen that a feeding device of a clamp body comprises: a feeding line body 2, a feeding station of a workpiece 5 is arranged at its downstream end, specifically, a conveyor belt is built in the feeding line body 2, the workpiece 5 is placed on the conveyor belt, so that the workpiece moves with the conveyor belt, and the conveyor belt is driven by a driving module 213 to make a cyclic motion; and

[0076] A gripping assembly 4, which grabs the workpiece 5 from the loading station and moves the workpiece 5 out of the loading line 2, so that the workpiece 5 located upstream of the loading line 2 flows to the loading station;

[0077] Wherein, further, a standby station is arranged at a position of the feeding line 2 adjacent to the feeding station, and the standby station is located at an upstream position of the feeding station; the workpiece 5 flowing in from the upstream end of the feeding line 2 is transmitted to the standby station and the workpiece 5 is restricted at the standby station, and after the workpiece 5 at the feeding station is moved out, the workpiece 5 at the standby station is moved to the feeding station;

[0078] In the actual use of the transmission line, due to the difference in the time required for each station in the automated assembly line to complete a processing, there is often a backlog of workpieces on part of the transmission line. The workpieces that have completed the processing subsequently will collide with the workpiece limited in front, which can easily cause the workpiece to shift in position after the collision. In order to ensure the accuracy of loading, a standby station is set to ensure the accuracy of the position of the workpiece transmitted between the loading station and the standby station.

[0079] In order to ensure the accuracy of the workpiece 5 flowing from the standby station to the loading station, the standby station includes a stopper 22 and a correction part 23. The movable end of the stopper 22 moves to the transmission path of the workpiece 5 on the loading line 2, thereby limiting the movement of the workpiece with the loading line 2. After the stopper 22 limits the position of the workpiece 5, the correction part 23 drives the workpiece 5 to rotate around the transmission direction of the workpiece 5 to adjust the position of the workpiece 5.

[0080] The workpiece 5 includes a pliers body 51 and a hook claw 53 extending outward from one end of the pliers body 51, so that the workpiece 5 is L-shaped as a whole, and a shoulder 531 with an arc-shaped surface is formed at the integral combination position of the hook claw 53 and the pliers body 51; specifically, the shoulder 531 is located at the bending position of the hook claw 53 and the pliers body 51; a hanging ear 52 is provided on the other end of the pliers body 51 opposite to the clamping claw 53, and the hanging ear 52 extends outward from both sides of the pliers body 51.

[0081] Since the outer surface of the clamp body 51 is in an arc shape, when the clamp body 51 is placed on the feeding line 2, the clamp body 51 and the feeding line 2 are in a tangent state. At the same time, when the feeding line 2 drives the workpiece 5, the workpiece 5 is prone to shaking, thereby causing the position of the workpiece 5 to deflect. When the clamping component 4 grasps the workpiece 5, the grasping angle is offset, resulting in an unsatisfactory grasping effect. For this reason, the workpiece 5 is driven to rotate by the correction part 23 to adjust the position of the workpiece 5, thereby ensuring the accuracy of the position of the workpiece 5, so that when it is moved to the feeding station, the clamping component 4 can accurately clamp the workpiece 5, thereby improving the feeding efficiency.

[0082] The feeding line 2 is provided with a guide module 211 and a pad 215 corresponding to the guide module 211. A gap is set between the pad 215 and the guide module 211, so that a guide groove is formed between the pad 215 and the guide module 211. When the workpiece 5 moves on the feeding line 2, the hanging ear 52 extends into the guide groove, thereby limiting the position of the workpiece 5 during the transmission process;

[0083] The guide module 211 includes a mounting frame 2111 and a guide plate 2112 mounted on the mounting frame 2111. The guide plate 2112 extends along the transmission direction of the workpiece 5. The mounting frame 2111 is mounted at both ends of the guide plate 2112.

[0084] The pad 215 is installed on the feeding line 2, and the pad 215 and the guide plate 2112 are arranged vertically and parallelly, so that the guide plate 2112 and the pad 215 form the guide groove.

[0085] The guide module 211 and the stopper 22 are sequentially arranged along the transmission direction of the workpiece 5 , and the correction part 23 is installed on the mounting frame 2111 close to the side of the stopper 22 .

[0086] The correction part 23 includes a push rod 232 and a push cylinder 231 driving the push rod 232 . When driven by the push cylinder 231 , the push rod 232 pushes the workpiece 5 to rotate.

[0087] The end of the push rod 232 that contacts the workpiece 5 forms a correction end 2321;

[0088] A protrusion 54 is provided on one end of the workpiece 5, and the push cylinder 231 drives the push rod 232 to move in the vertical direction, so that the correction end 2321 is pressed on the side of the protrusion 54 to drive the workpiece 5 to rotate; the protrusion 54 is located at one end where the hanging ear 52 is provided, and the correction part 23 is located at the upstream position of the stopper 22;

[0089] The end surface shape of the correction end 2321 corresponds to the side surface of the protrusion 54 , so that the push rod 232 pushes the workpiece 5 to rotate until the end surface of the correction end 2321 is in contact with the side surface of the protrusion 54 .

[0090] The blocking portion 22 includes a support 221 and a driving element 222 installed on the support 221. A block 223 for blocking the workpiece 5 is installed on the power output end of the driving element 222. Driven by the driving element 222, the block 223 moves in a vertical direction, so that the block 223 moves to the transmission path of the workpiece 5 to limit the workpiece from moving with the loading line 2. The driving element 222 is respectively installed on both sides of the support 221, so that the two blocks 223 limit the position of the workpiece 5 at the same time. At the same time, one of the blocks 223 is used to limit the subsequent movement of the workpiece 5 to the standby station.

[0091] The support 221 is further provided with a guide rail 224 , and a sliding groove of the stopper 223 is provided on the guide rail 224 . The stopper 223 is driven to move along a direction defined by the guide rail 224 by the driving element 222 .

[0092] The clamping assembly 4 comprises:

[0093] Robotic arm 43;

[0094] A connecting portion 41 mounted on a movable power output end of the mechanical arm 43; and

[0095] At least two clamping parts 42 are arranged circumferentially on the side wall of the connecting part 41, which are used to clamp the workpiece 5; in a preferred embodiment, the number of the clamping parts 42 is three, and the clamping parts 42 are evenly arranged circumferentially on the side of the connecting part 41, so that multiple workpieces 5 can be transported in a single transmission process, thereby improving the transmission efficiency;

[0096] Driven by the robot arm 43 , the clamping portion 42 moves to the loading station of the loading line 2 , grabs the workpiece 5 and takes the workpiece 5 away from the loading line 2 .

[0097] The clamping portion 42 includes a first clamping module 422 corresponding to the pressing shoulder 531 and a second clamping module 424 for clamping the other end of the workpiece 5. The first clamping module 422 is pivotally connected to the first clamping jaw 423. The driver 421 in the clamping portion 42 drives the first clamping module 422 and the second clamping module 424 to close, and drives the first clamping jaw 423 to rotate to adjust the first clamping jaw 423 to fit on the shoulder 531.

[0098] The two clamping modules of the clamping portion 42 respectively clamp the shoulder 531 and the other end of the clamp body 51 corresponding to the shoulder 531. The other end surface of the clamp body 51 is flat, which is convenient for the clamping claw to fit on the clamp body 51. On one end of the shoulder 531, due to the limitation of the shape of the shoulder 531 itself, when the first clamping claw 423 contacts the arc-shaped shoulder 531 surface, when a general feeding device clamps the workpiece 5, the first clamping claw 423 and the shoulder 531 are in a tangent state, resulting in the force point being only at one point. If the placement position of the workpiece 5 is offset before grasping, the force point of the first clamping claw 423 and the shoulder 531 is not at a fixed point, and the driver 421 The two clamping modules are driven together, and the clamping force of the two clamping modules will drive the workpiece 5 to adjust its own position to meet the clamping of the clamping jaws on both sides. At this time, the first clamping jaw 423 and the shoulder 531 have relative sliding positions at the points of application, resulting in a reduction in the friction between the first clamping jaw 423 and the shoulder 531, which can easily cause slippage after grasping. At the same time, in the process of adjusting the workpiece 5, there is also a situation where the point of application of the first clamping jaw 423 is reduced due to the offset of the position of the workpiece 5. In the above case, due to the reduction in the number of points of application, in the project of using the clamping force to adjust the position of the workpiece, the pressure at the point of application of the first clamping jaw 423 and the shoulder 531 is relatively large, causing damage to the workpiece 5.

[0099] In the present embodiment, the first rotatable clamping jaw 423 is used. When the driver 421 drives the two clamping molds to close together, the first clamping jaw 423 is rotated by the support force of the workpiece 5 to adjust to the fixed force point with the shoulder 531. As the driver 421 drives the two clamping molds to close together, the first clamping jaw 423 is driven by the force to drive the workpiece 5 to rotate around the pivot axis. At this time, the force point of the first clamping jaw 423 and the shoulder 531 is relatively fixed, thereby ensuring its clamping effect. In the preferred embodiment shown in the figure, the first clamping jaw 423 includes a connecting column 4231 and a connecting column 4231 facing one side. It extends outward to form a protruding clamping end 4232; there are two hooks 53, the position of the clamping end 4232 corresponds to the hook 53, and the clamping end 4232 is arranged along the extension direction of the connecting column 4231; when the placement position of the workpiece 5 is deflected, driven by the driver 421, the first clamping jaw 423 first conflicts with one of the hooks 53, and the first clamping jaw 423 will rotate due to the supporting force of the conflicting hook 53, thereby preferentially making the first clamping jaw 423 rotate to a position tangent to the two hooks 53, and at this time, the fulcrum points of the first clamping jaw 423 and the two hooks 53 are fixed fulcrum points.

[0100] At the same time, since the first clamping jaw 423 rotates to adjust to a fixed fulcrum point with the shoulder 531, the number of fulcrum points between the first clamping jaw 423 and the shoulder 531 is guaranteed, avoiding the problem of increased pressure at the fulcrum position due to a reduction in the number of fulcrum points.

[0101] A buffer block 4233 is installed on the side of the clamping end 4232 corresponding to the hook claw 53. When the first clamping jaw 423 is pressed onto the workpiece 5, the buffer block 4233 elastically deforms to fit the hook claw 53. The elastic deformation of the buffer block 4233 increases the contact area with the hook claw 53, thereby increasing the friction and reducing the probability of falling off. At the same time, the elastic deformation reduces the damage to the workpiece 5 caused by rigid contact and effectively absorbs the force generated by the impact when the first clamping jaw 423 contacts the workpiece 5.

[0102] The loading station includes a limiting portion 212, the workpiece 5 moves to abut against the limiting portion 212, thereby limiting the movement of the workpiece 5, the limiting portion 212 is located at the moving terminal position of the workpiece 5 on the loading line 2, the workpiece 5 moves to abut against the limiting portion 212, thereby limiting the movement of the workpiece 5, one end of the workpiece 5 provided with a hook 53 abuts against the limiting portion 212, the limiting portion 212 is provided with a clearance opening 2121, the position of the clearance opening 2121 corresponds to the hook 53, the first clamping jaw 423 extends into the clearance opening 2121; the clamping end 4232 extends into the clearance opening 2121;

[0103] The clearance opening 2121 is provided with a sensing module 2122 for sensing the workpiece 5 . The clamping end 4232 is provided with a notch 4235 . When the clamping end 4232 extends into the clearance opening 2121 , the sensing module 2122 is disposed in the notch 4235 .

[0104] In a preferred embodiment, the loading line 2 is equipped with two conveyor belts so that the loading line 2 can simultaneously convey two workpieces 5, thereby improving the loading efficiency. At the same time, the conveying directions of the two conveyor belts are parallel. At this time, four clearance openings 2121 are provided on the limiting portion 212 to correspond to the hooks 53 on the two workpieces 5. Two sensing modules 2122 are provided in the clearance openings 2121 to respectively detect the positions of the workpieces 5 transmitted on the two conveyor belts. At the same time, the two sensing modules 2122 are arranged in the clearance openings 2121 on the two outer sides corresponding to the loading line 2. In order to facilitate the first clamp 423 to clamp the workpieces in the two conveyor belts, the two clamping ends 4232 are provided with the notches 4235 to simplify the control logic.

[0105] The loading station also includes a blocking module 214, which includes a side mounting plate 2141 and a limiting rod 2142 installed on the side mounting plate 2141. The side mounting plate 2141 is installed on the loading line 2. When the workpiece 5 is transferred to the loading station, the limiting rod 2142 abuts against the hanging ear 52, and cooperates with the limiting part 212 to limit the position of the workpiece.

[0106] The second clamping module 424 includes a clamping jaw bracket 4241 and a second clamping jaw 4242 installed on the clamping jaw bracket 4241 ; the second clamping jaw 4242 abuts against the bottom of the hanging ear 52 ; specifically, the bottom surface of the hanging ear 52 is a flat surface, which facilitates the clamping of the second clamping jaw 4242 .

[0107] In a preferred embodiment, the ears 52 are arranged on the corresponding two sides of the clamp body 51, the clamp bracket 4241 is C-shaped, and the second clamp 4242 is installed at the two end positions of the clamp bracket 4241, so that the second clamp 4242 on the two ends of the clamp bracket 4241 can extend to the bottom of the ear 52.

[0108] The surface of the second clamping jaw 4242 that contacts the hanging ear 52 is provided with undulating tooth-shaped protrusions to form a contact surface 42421 of the second clamping jaw 4242 , so that the clamping effect of the second clamping jaw 4242 is better.

[0109] In a preferred embodiment, the first clamping module 422 includes a base 4231 , and the first clamping jaw 423 is pivotally connected to the base 4231 .

[0110] The base 4231 is provided with a through slot penetrating two opposite side surfaces thereof, and the first clamping jaw 423 is disposed in the through slot.

[0111] Furthermore, the base 4231 is further installed with a mounting plate 4223, and the mounting plate 4223 covers the through slot, so that a receiving cavity 4225 of the first clamping claw 423 is formed between the base 4231 and the mounting plate 4223;

[0112] A pin groove 4234 is provided on the surface of the first clamping jaw 423, and a deep groove is provided at the position of the through groove corresponding to the pin groove 4234 on the first clamping jaw 423. The pin groove 4234 on the first clamping jaw 423 and the deep groove on the inner wall of the through groove form an installation position for accommodating the pin 4224, so that the first clamping jaw 423 can rotate around the axis direction of the pin 4224.

[0113] Furthermore, an elastic layer 4222 is provided between the first clamping jaw 423 and the mounting plate 4223, and the elastic layer 4222 rebounds and resets to facilitate the next grasping;

[0114] At the same time, the surface of the hook 53 extending outward from the caliper body 51 is tilted downward relative to the shoulder 531 to form a slope 532;

[0115] After the first clamping jaw 423 is pressed on the shoulder 531, the first clamping jaw 423 is driven by the driver 421 to press the elastic layer 4222 to deform the elastic layer 4222, so that the first clamping jaw 423 deflects radially downward of the pin shaft 4224, and then the first clamping jaw 423 tilts and fits the slope 532;

[0116] Through the elastic deformation of the elastic layer 4222, not only the first clamping jaw 423 can rotate around the axis direction of the pin shaft groove 4234, but also the first clamping jaw 423 can rotate around the extension direction of the connecting column 4231 thereon, so that the first clamping jaw 423 is turned over to achieve the purpose of the first clamping jaw 423 being attached to the slope surface 532, thereby increasing the contact area between the first clamping jaw 423 and the workpiece 5, and further improving the clamping effect;

[0117] Specifically, when the driver 421 drives the first clamping module 422, the first clamping jaw 423 first rotates to fit the shoulder 531. As the driver 421 continues to drive, the first clamping module 422 rotates to adjust the position of the workpiece 5. When the driver 421 further drives the first clamping module 422, the first clamping jaw 423 drives the elastic deformation of the elastic layer 4222, so that the first clamping jaw 423 flips over, thereby making the first clamping jaw 423 fit the slope 532 to achieve a better clamping effect.

[0118] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to specific details.
