Description

Technical Field

[0001] The invention relates to the field of non-standard automated assembly, and in particular to automated processing equipment applied to a clamp body. Background Art

[0002] In the field of non-standard automation, especially in the process of machining the pliers body, the inventors found that there are at least the following problems in the existing machining process:

[0003] Firstly, since the shape and structure of the pliers body itself are relatively complex and its surface is often an arc-shaped surface, different parts of the pliers body need to be processed, wherein the parts that need to be processed include at least the cylinder body and the hook claws located at the corresponding two ends of the pliers body. It is difficult to simultaneously process the overall shape of the pliers body using only a single processing station. Specifically, the clamping position of the carrier on the processing station limits the processing part of the pliers body. Therefore, the existing technology often uses multiple processing to process the pliers body one by one. In the existing processing equipment, each station is often equipped with a gripping device, which grips the pliers body through the gripping device so that the pliers body can flow between the corresponding station and the conveyor belt. However, in order to configure multiple gripping devices, the floor space of the entire processing equipment is increased. At the same time, during the processing process, each processing station has a different processing speed, and it is easy for the pliers body to be accumulated at the station with a long processing time on the transmission line, resulting in low processing efficiency. Arranging more devices for stations with long processing time to solve the problem of pliers body accumulation will also increase the volume of the entire equipment.

[0004] In view of this, it is necessary to develop an automated processing equipment for the pliers body to solve the above problems. Summary of the invention

[0005] In view of the shortcomings existing in the prior art, the main purpose of the present invention is to provide an automated processing equipment applied to the clamp body, which enables the same workpiece grabbing robot arm to move on a guide rail, so that the robot arm can move between the loading station, processing station, and unloading workpiece, thereby realizing the circulation of workpieces in each station, thereby simplifying the layout structure of the entire equipment and making the processing equipment more compact.

[0087] In a preferred embodiment, the workpiece 5 to be processed by the automatic processing equipment in the present invention is a pliers body, which specifically 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 lug 52 is provided on the other end of the pliers body 51 opposite to the clamping claw 53, and the lug 52 extends outward from both sides of the pliers body 51; a cylindrical cylinder body 55 is extended from the side surface of one end of the pliers body 51 where the lug 52 is provided.

[0088] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown in the figure, it can be seen that an automated processing device applied to a pliers body comprises: a forming assembly 1, on which a plurality of forming stations for processing a workpiece 5 are arranged;

[0089] The loading line 2 has a loading station for the workpiece 5 at its downstream end. Specifically, the loading line 2 has a built-in conveyor belt, and the workpiece 5 is placed on the conveyor belt so that the workpiece moves with the conveyor belt. The conveyor belt is driven by a driving module 213 to make a cyclic motion.

[0090] A material unloading component 3 is provided with a material unloading station, and the material unloading station is provided at the upstream end of the material unloading component 3. A conveyor belt is also provided in the material unloading component 3, and the workpiece 5 transferred to the material unloading station is moved out of the automated processing equipment through the conveyor belt; and

[0091] A gripping assembly 4, which grabs the workpiece 5 from the loading station, and the gripping assembly 4 includes a guide rail 44 and a mechanical arm 43 moving along the extension direction of the guide rail 44;

[0092] The molding station, loading station and unloading station are arranged along the extension direction of the guide rail 44, and a clamping member is installed on the power output end of the mechanical arm 43, and the clamping member includes a plurality of clamping parts 42 for grasping the workpiece;

[0093] The robot arm 43 moves on the guide rail 44 so that the clamping portion 42 grabs the workpiece 5 from the loading station and transfers it to the forming station, and then grabs the formed workpiece 5 from the forming station and transfers it to the unloading station.

[0094] Furthermore, the forming component 1 includes no less than two forming parts, each of which has the processing station built in; the forming part is used to process and form the workpiece 5, and the forming part, the loading line 2 and the unloading component 3 are located on the corresponding sides of the guide rail 44; the forming part has a built-in carrier for receiving the workpiece 5.

[0095] Specifically, there are four forming parts, which are symmetrically arranged on both sides of the guide track 44, and the loading line 2 and the unloading assembly 3 are arranged on the corresponding two sides of the guide track 44; the forming parts are respectively provided with a hanging ear processing station 11, a cylinder cavity processing station 12, a through hole processing station 13, and a hook processing station 14;

[0096] The ear processing station 11 is used to process the ear 52 of the workpiece 5 and the end face of the cylinder body 55; the cylinder body cavity processing station 12 is used to process the inside of the cylinder body 55 so that the cylinder body 55 is hollow to form a cavity; the through hole processing station 13 is used to process the through hole on the ear 52 and the through hole at the bottom of the cylinder body 55 cavity; the claw processing station 14 is used to form the claw 53; because the forming part processes different parts of the workpiece 5, the carrier used to carry the workpiece 5 in the forming part is also different, and the difference in the carrier is likely to affect the clamping component structure for grasping the workpiece 5.

[0097] However, due to the change in the structure of the clamping member, the clamping member needs to be replaced in automated production. In the existing technology, due to the difficulty of replacing the clamping member, independent clamping members are often used to correspond to the different forming parts, thereby increasing the number of clamping members and increasing the floor space when arranging the entire automated processing equipment.

[0098] In order to solve the above problems, in the preferred embodiment, it is further proposed that the clamping assembly 4 further includes a carrying platform 45, the carrying platform 45 is located on the guide track 44, and the carrying platform 45 moves with the mechanical arm 43; the carrying platform 45 can carry spare clamping components, so that after moving to the corresponding processing station, the mechanical arm 43 replaces the corresponding clamping components;

[0099] The clamping member is detachably connected to the power output end of the robot arm 43 , and the supporting platform 45 is provided with a first material receiving portion 452 and a second material receiving portion 453 for receiving the workpiece 5 , wherein the first material receiving portion 452 is used for receiving the clamping member detached from the robot arm 43 .

[0100] In order to facilitate the automated assembly and disassembly of the clamping member, in a specific embodiment, a connecting member is provided on the robot arm 43. Specifically, the connecting member includes a connecting column and a protrusion extending outwardly is provided on the circumferential side wall of the connecting column. The clamping member is sleeved on the connecting column, and the protrusion abuts against the clamping member to form a fixed connection structure. The protrusion is movable and retractable. When the protrusion retracts radially toward the connecting column, the clamping member is disconnected from the connecting column, so that the clamping member can be detached from the robot arm 43.

[0101] Furthermore, the guide rail 44 has a built-in linear motor 441 , and the carrying platform 45 and the robotic arm 43 are installed on the power output end of the linear motor 441 , so that the linear motor 441 drives the carrying platform 45 and the robotic arm 43 to move at the same time.

[0102] The second material receiving portion 453 is arranged at the edge of the carrying platform 45;

[0103] The second material receiving portion 453 includes a limiting rod, the position of which corresponds to the hook 52. When the workpiece 5 grasped by the clamping assembly 4 is placed on the second material receiving portion 453, the hook 52 is sleeved on the limiting rod to limit the position of the workpiece.

[0104] In a preferred embodiment, a standby station is provided at a position of the feeding line 2 adjacent to the feeding station, and the standby station is located upstream 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;

[0105] In the actual use of the transmission line, due to the difference in the time required for each station in the automated processing 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 position of the workpiece to shift 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.

[0106] 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.

[0107] 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.

[0108] 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;

[0109] 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.

[0110] 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.

[0111] 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 .

[0112] 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.

[0113] The end of the push rod 232 that contacts the workpiece 5 forms a correction end 2321;

[0114] 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;

[0115] 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 .

[0116] 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.

[0117] 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 .

[0118] The clamping member comprises:

[0119] A connecting portion 41 mounted on a movable power output end of the mechanical arm 43; and

[0120] 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;

[0121] 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 .

[0122] 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.

[0123] The two clamping modules of the clamping part 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 the general automated processing equipment 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 42 1 drives the two clamping modules to close 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 a relative sliding position, resulting in a reduction in the friction between the first clamping jaw 423 and the shoulder 531, which is easy to cause slippage after grasping. At the same time, in the process of adjusting the workpiece 5, there is also a situation where the first clamping jaw 423's force point is reduced due to the offset of the workpiece 5 position. In the above case, due to the reduction in the number of force points, in the project of adjusting the workpiece position by clamping force, the pressure at the force point of the first clamping jaw 423 and the shoulder 531 is relatively large, so as to cause damage to the workpiece 5.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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;

[0128] 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 .

[0129] 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.

[0130] 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.

[0131] 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 .

[0132] 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.

[0133] 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.

[0134] 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 .

[0135] 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.

[0136] 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;

[0137] 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.

[0138] 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;

[0139] 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;

[0140] 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;

[0141] 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;

[0142] 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.

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.
