Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and in particular to a novel manipulator gripping arm structure. Background Art

[0002] As a kind of auto parts, brake pads are often pressed and formed by hot presses during the production process. The hot press pressing process includes three processes: adding friction material into the hot press mold, spreading the friction material and taking out the formed brake pads.

[0003] For example, Chinese patent CN109514912A proposes a fully automatic brake pad production equipment; it includes a feeding device, a weighing device and several hot presses, the hot press and the weighing device are arranged in a line, and the weighing device is arranged at the end, and the feeding device is arranged at the front side of the hot press and the weighing device; the feeding device includes a feeding frame, and the middle mold unit and the lower mold unit of the hot press can extend into the interior of the feeding frame; the first manipulator, the second manipulator and the third manipulator are arranged on the feeding frame from right to left in sequence; the first manipulator feeds the friction material in the material frame into the mold cavity of the hot press, the second manipulator is used to flatten the powder in the mold cavity of the hot press, and the third manipulator is used to collect the finished product.

[0004] Although this type of equipment can realize the automated production of brake pads, the robots used are expensive, occupy a large space, and require high-precision coordination with each other. Therefore, how to add friction material to the press mold, spread the friction material, and remove the formed brake pads through one robot is a problem that needs to be solved at present. Summary of the invention

[0005] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes a new type of robot gripper arm structure.

[0006] The technical solution adopted by the present invention to solve the technical problem is:

[0007] A novel manipulator gripping arm structure includes a manipulator body slidably arranged on a workshop floor rail and an actuator connected to a rotating arm of the manipulator body; the actuator includes:

[0008] The mounting seat is arranged on the rotating arm of the robot body, so that when the robot body switches actions, the mounting seat is rotated;

[0009] The clamping part is arranged on the first mounting surface of the mounting seat to feed the friction material in the material rack into the hot press mold;

[0010] A spreading part is arranged on the second mounting surface of the mounting seat to spread the friction material in the hot press mold;

[0011] The adsorption part is arranged on the third mounting surface of the mounting seat to take the molded brake pad in the hot press mold.

[0012] In this solution, the clamping portion further comprises:

[0013] A buffer assembly is arranged on the first mounting surface of the mounting seat;

[0014] The clamping assembly is connected to the buffer assembly and is used to clamp the material rack.

[0015] In this solution, the buffer component further comprises:

[0016] There are four guide rods which are vertically slidably arranged on the mounting seat;

[0017] There are four limit seats, each of which is arranged at the top of a guide rod;

[0018] A mounting plate, which has one piece and is connected to the bottom ends of the four guide rods and is provided with four strip holes for allowing bolts to be inserted;

[0019] There are four buffer springs, each of which is sleeved outside a guide rod and located between the mounting seat and the mounting plate.

[0020] In this solution, the clamping assembly further comprises:

[0021] The outer shell has two holes arranged at the corresponding positions of the four strip holes, so that the distance between the two outer shells can be adjusted, thereby being able to meet the clamping operation of racks of different specifications and sizes;

[0022] There are four telescopic cylinders, and every two telescopic cylinders are symmetrically arranged in one housing;

[0023] There are four movable seats, each of which is connected to a telescopic end of a telescopic cylinder and is horizontally slidably arranged on the housing, so that two relatively telescopic cylinders operate to move two relatively movable seats closer to or farther from each other;

[0024] There are four upper clamping plates, each connected to a moving seat, and forming an L-shaped structure;

[0025] There are four lower hook plates, each of which is connected to an upper clamping plate, so that a C-shaped clamping opening for clamping the material rack is formed between the lower hook plates and the upper clamping plates.

[0026] In this solution, the clamping assembly further includes:

[0027] There are two intermediate seats, each of which is arranged in two outer shells;

[0028] There are four horizontal springs, and every two horizontal springs are symmetrically arranged about an intermediate seat;

[0029] There are four contact plates, and every two contact plates are connected to a horizontal spring, so as to contact with the two moving seats when they approach each other, so as to achieve the purpose of buffering.

[0030] In this solution, a locking assembly is installed on the clamping part to reduce the risk of the clamping part falling off during the process of clamping the material rack. The locking assembly includes:

[0031] There are two hollow plates and they are horizontally arranged at the positions of the two lower hook plates;

[0032] There are two pressure sensors, each of which is arranged inside a hollow plate;

[0033] There are two magnetic seats, each of which is arranged outside a pressure sensor;

[0034] There are two plug plates, which are horizontally arranged at the positions of the other two lower hook plates. When the two plug plates are respectively connected to the two hollow plates, the plug plates collide with the magnetic seat, and the pressure sensor receives the pressure signal, so that the magnetic seat magnetically attracts the plug plates, thereby fixing the connection between the plug plates and the hollow plates, and finally making the bottom of the C-shaped clamp in a closed state, which has a limiting effect.

The eccentric motor is operated to make the spreading rods perform excitation action. The spreading rods contact the friction material, so that the friction material at the bottom and the friction material at the top are exchanged with each other, so that the friction material is fully and evenly spread.

[0041] In this solution, the paving part further includes:

[0042] The number of spreading springs is the same as that of spreading rods and they are arranged at the bottom of the spreading rods. Through the arrangement of the spreading springs, when the eccentric motor drives the spreading rods to operate, the excitation effect of the spreading spring part is stronger, thereby making the amplitude and frequency generated during the contact with the friction material larger, thereby improving the spreading and mixing effect of the friction material.

[0043] In this solution, the adsorption part further comprises:

[0044] The beam assembly is arranged on the third mounting surface of the mounting seat;

[0048] There is one mounting beam connected to the connecting frame, and the mounting beam is provided with a plurality of positioning holes along its length direction;

[0049] There are four fixed beams which are arranged along the length direction of the mounting beam and are correspondingly arranged at the positions of four positioning holes so that the spacing between the four fixed beams can be adaptively adjusted, and each fixed beam is symmetrically provided with two adjustment holes.

[0050] In this solution, the adsorption component further comprises:

[0051] There are eight butt-jointing pipes, each connected to an adjusting hole;

[0052] There are eight negative pressure suction nozzles, each connected to the bottom end of a butt-jointed pipe, and two negative pressure suction nozzles on the same fixed beam form an adsorption position for adsorbing the molded brake pad in the hot press mold;

[0053] There are eight connectors, each of which is connected to the top of a butt pipe;

[0054] There are eight bases, each of which is fixedly arranged outside a butt-jointed pipe and below the fixed beam, and the size of which is larger than the size of the adjustment hole;

[0055] There are eight top seats, each of which is slidably sleeved outside a butt-jointed tube and is located above the fixed beam, and has a size larger than the adjustment hole;

[0056] There are eight nuts, each of which is threadedly connected to a butt pipe and is located above the top seat to press the top seat onto the fixed beam, thereby finally fixing the position of each group of adsorption components.

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] 1. The present invention adopts an integrated arrangement of the clamping part, the spreading part and the adsorption part, so that the three processes of adding friction material into the hot press mold, spreading the friction material and taking out the formed brake pad can be realized by one robot, which not only saves costs and reduces space occupation, but also uses one robot to automate the three processes, omitting multiple actions that need to be coordinated between the three robots, and the conversion between the parts is executed more quickly, which greatly improves the production and processing efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The specific structure and layout of the manipulator body 1 are prior arts and are known to those skilled in the art. Therefore, the present invention will not be described in detail.

[0077] The execution part is arranged on the rotating arm of the robot body 1, so that when the robot body 1 performs action switching, the execution part is caused to perform a rotation action;

[0078] The executive department includes:

[0079] The mounting seat 2 is arranged on the rotating arm of the robot body 1, so that when the robot body 1 switches actions, the mounting seat 2 is rotated;

[0080] The clamping part 3 is arranged on the first mounting surface of the mounting seat 2 to feed the friction material in the material rack into the hot press mold;

[0082] The adsorption part 5 is arranged on the third mounting surface of the mounting seat 2 to take the molded brake pad in the hot press mold.

[0083] The present invention comprises the following steps in its specific implementation process:

[0084] Step 1: The clamping part 3 feeds the first friction material in the material rack into the hot press mold, the manipulator body 1 performs the first action switching, and the spreading part 4 starts to spread and mix the first friction material in the hot press mold until the spreading action is completed;

[0085] Step 2: The manipulator body 1 performs a second action switching, and the clamping part 3 feeds the second friction material in the material rack into the hot press mold until the feeding action is completed;

[0086] Step 3: the manipulator body 1 performs the third action switching, and the spreading part 4 starts to spread the second friction material in the hot press mold until the spreading action is completed;

[0087] Step 4: the manipulator body 1 performs the fourth action switching, and the adsorption part 5 takes the molded brake pad in the hot press mold until the taking action is completed;

[0088] Step 5: Repeat the above steps 1 to 4 to achieve continuous loading and spreading of the first friction material and the second friction material and the material removal of the formed brake pad.

[0089] In the above embodiment, the structure of the clamping portion 3 is specifically as follows:

[0090] See attached Figure 3 , Attachment Figure 5 And attached Fig.11 As shown, the clamping portion 3 includes:

[0091] The buffer assembly 31 is arranged on the first mounting surface of the mounting seat 2, and includes:

[0092] There are four guide rods 311 and they are vertically slidably arranged on the mounting base 2;

[0093] There are four limit seats 312, each of which is arranged at the top of a guide rod 311;

[0094] The mounting plate 313 has one piece and is connected to the bottom ends of the four guide rods 311, and is provided with four strip holes 3131 for allowing bolts to be inserted;

[0095] There are four buffer springs 314 , each of which is sleeved outside a guide rod 311 and located between the mounting seat 2 and the mounting plate 313 .

[0096] The clamping portion 3 also includes:

[0097] The clamping assembly 32 is connected to the buffer assembly 31 and is used to clamp the material rack, and includes:

[0098] The outer shell 321 has two and is arranged at the corresponding positions of the four bar holes 3131, so that the distance between the two outer shells 321 can be adjusted, thereby being able to meet the clamping operation of racks of different specifications and sizes;

[0099] There are four telescopic cylinders 322, and every two telescopic cylinders 322 are symmetrically arranged in a housing 321;

[0100] There are four movable seats 323, each connected to a telescopic end of a telescopic cylinder 322, and horizontally slidably disposed on the housing 321, so that two relative telescopic cylinders 322 operate to move two relative movable seats 323 closer to or farther from each other;

[0101] There are four upper clamping plates 324, each connected to a movable seat 323, and forming an L-shaped structure;

[0102] There are four lower hook plates 325, each connected to one upper clamping plate 324, so that a C-shaped clamping opening for clamping the material rack is formed between the lower hook plates 325 and the upper clamping plates 324;

[0103] There are two intermediate seats 326, each of which is disposed in two outer shells 321;

[0104] There are four horizontal springs 327, and every two horizontal springs 327 are symmetrically arranged about a middle seat 326;

[0105] There are four contact plates 328 , and every two contact plates 328 are connected to a horizontal spring 327 , so as to contact with the two moving seats 323 when they approach each other, thereby achieving a buffering purpose.

[0106] During the implementation of this plan, please refer to the attached Fig.11 As shown, according to the spacing between the four clamping holes of the material rack, the distance between the two shells is adjusted so that the spacing between the four C-shaped clamps matches the spacing between the four clamping holes of the material rack, and the four C-shaped clamps are respectively connected to the four clamping holes of the material rack to firmly clamp and fix the material rack.

[0107] In the above scheme, in order to reduce the risk of the clamping part 3 falling off during the process of clamping the material rack, for this purpose, refer to the attached Figure 6 As shown, a locking assembly 6 is installed on the clamping portion 3. Specifically, the locking assembly 6 includes:

[0108] There are two hollow plates 61 and they are horizontally arranged at the positions of two lower hook plates 325;

[0109] There are two pressure sensors 62, each of which is disposed inside a hollow plate 61;

[0110] There are two magnetic seats 63, each of which is arranged outside a pressure sensor 62;

[0111] There are two plug plates 64 and they are horizontally arranged at the positions of the other two lower hook plates 325. When the two plug plates 64 are respectively connected to the two hollow plates 61, the plug plates 64 collide with the magnetic seat 63, and the pressure sensor 62 receives the pressure signal, so that the magnetic seat 63 magnetically attracts the plug plates 64, thereby fixing the plug plates 64 and the hollow plates 61, and finally making the bottom of the C-shaped clamp in a closed state, with limit;

[0112] During the specific implementation process, the locking assembly 6 is used in conjunction with the clamping assembly 32. When in use, since the plug plate 64 and the hollow plate 61 are fixedly arranged on the lower hook plate 325, the plug plate 64 and the hollow plate 61 move with the movement of the lower hook plate 325 (the operation of the telescopic cylinder 322 causes the lower hook plate 325 to move closer to the center or away from the outside); when loading, the plug plate 64 is inserted into the hollow plate 61, and the plug plate 64 contacts the magnetic seat 63. At this time, the pressure sensor 62 receives the pressure signal, and the magnetic seat 63 magnetically attracts the plug plate 64 At the same time, the lower hook plate 325 stops moving toward the center (the telescopic cylinder 322 no longer operates). In this state, the plug plate 64 is fixedly connected to the hollow plate 61, so that the bottom of the C-shaped clamp is in a closed state, which has an anti-falling effect; when unloading, the lower hook plates 325 start to move away from each other (the telescopic cylinder 322 operates). At the same time, the magnetic seat 63 no longer magnetically attracts the plug plate 64. In this state, the plug plate 64 is away from the hollow plate 61, so that the bottom of the C-shaped clamp is in an open state, and normal unloading operations can be achieved.

[0113] In the above embodiment, the structure of the paving part 4 is specifically as follows:

[0114] See attached Figure 3 and attached Figure 7 As shown, the paving section 4 includes:

[0115] The bracket 41 has one and is disposed on the second mounting surface of the mounting base 2;

[0116] A horizontal plate 42, having one and being vertically connected to the bracket 41;

[0117] Eccentric motors 43, four in number and arranged on the horizontal plate 42;

[0118] There are four connecting plates 44, each connected to a motor shaft of an eccentric motor 43;

[0119] There are a plurality of spreading rods 45 which are respectively arranged at the bottom of the four connecting plates 44 to form four spreading positions. The eccentric motor 43 is operated to make the spreading rods 45 perform an exciting action. The spreading rods 45 contact with the friction material, so that the friction material at the bottom of the hot press mold and the friction material at the top are exchanged with each other, thereby making the friction material fully and evenly spread.

[0120] In the above scheme, the spreading effect of the spreading part 4 on the friction material in the hot press mold is taken into consideration. Figure 8 As shown, the paving section 4 also includes:

[0121] The number of spreading springs 46 is the same as that of the spreading rods 45 and they are arranged at the bottom of the spreading rods 45. The arrangement of the spreading springs 46 makes it possible for the eccentric motor 43 to drive the spreading rods 45 to operate, and the excitation effect of the spreading springs 46 is stronger, thereby making the amplitude and frequency of the vibrations generated during the contact with the friction material larger, thereby improving the spreading and mixing effect of the friction material.

[0122] In the above embodiment, the structure of the adsorption part 5 is specifically as follows:

[0123] See attached Figure 3 , Attachment Fig. 9 and attached Fig.10 As shown, the adsorption part 5 includes:

[0124] The beam assembly 51 is arranged on the third mounting surface of the mounting seat 2, and comprises:

[0125] The connecting frame 511 has one and is disposed on the third mounting surface of the mounting seat 2;

[0126] There is one mounting beam 512 connected to the connecting frame 511, and the mounting beam 512 is provided with a plurality of positioning holes 5121 along its length direction;

[0127] There are four fixed beams 513 arranged along the length direction of the mounting beam 512 and correspondingly arranged at the positions of four positioning holes 5121 so that the spacing between the four fixed beams 513 can be adaptively adjusted, and each fixed beam 513 is symmetrically provided with two adjustment holes 5131.

[0128] The adsorption unit 5 further includes:

[0129] There are eight groups of adsorption components 52, and every two groups of adsorption components 52 are symmetrically arranged on a fixed beam 513. The two groups of adsorption components 52 on the same fixed beam 513 form an adsorption position for adsorbing the brake pad, which includes:

[0130] There are eight butt-joining pipes 521, each connected to an adjusting hole 5131;

[0131] There are eight negative pressure suction nozzles 522, each connected to the bottom end of a butt joint 521;

[0132] There are eight connectors 523, each of which is connected to a top end of a butt-joint pipe 521;

[0133] There are eight bases 524, each of which is fixedly disposed on a butt joint 521 and is located below the fixed beam 513, and the size of which is larger than the size of the adjustment hole 5131;

[0134] There are eight top seats 525, each of which is slidably sleeved on a butt joint 521 and is located above the fixed beam 513, and has a size larger than that of the adjustment hole 5131;

[0135] There are eight nuts 526 , each of which is threadedly connected to a butt joint 521 and is located above the top seat 525 to press the top seat 525 onto the fixed beam 513 , thereby finally fixing the position of each group of adsorption components 52 .

[0136] It is worth noting that in the specific implementation of the present invention, the number of spreading positions and adsorption positions is determined according to the number of hot press molds. For example, if there are four hot press molds, there are four spreading positions and adsorption positions. If there are five hot press molds, there are five spreading positions and adsorption positions, and the three numbers correspond to each other. When in use, each spreading position corresponds to a hot press mold, and spreads the friction material therein, and each adsorption position corresponds to a hot press mold, and adsorbs the brake pad formed therein. The change in the number of spreading positions and adsorption positions can simultaneously realize the corresponding operations of all the molds of the hot press, thereby improving the processing efficiency of the brake pad.

[0137] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
