Description

Technical Field

[0001] The invention relates to the technical field of an automated production line for a brake caliper bracket, and in particular to a feeding device for an automated production line for a brake caliper bracket. Background Art

[0002] The automobile brake caliper bracket parts are an important part of the automobile braking system. The structure of the automobile brake caliper bracket 1 is shown in Figure 1-2 As shown, an irregular special-shaped body includes a bracket body 1a and side portions 1b extending backward on both sides of the bottom of the bracket body 1a, wherein the bracket body 1a is an irregular, approximately bridge-shaped plate with two ends facing downward and the middle facing upward compared to the two ends. In addition, forward-protruding protrusions 1c are provided on both sides of the upper part of the bracket body 1a.

[0003] The existing automatic production line of brake caliper bracket usually includes a broaching device and a loading and unloading device, wherein the loading and unloading device generally transports the brake caliper bracket through a conveyor belt. Specifically, the brake caliper bracket to be processed is loaded from one end of the conveyor belt and then transported to the second end through the conveyor belt. A manipulator is provided at the second end of the conveyor belt to clamp the workpiece from the conveyor belt and then transfer it to the processing part. For example, the Chinese invention patent with application number: CN201510112209.1 (authorization announcement number: CN104759933B) discloses such a "conveying device for an automatic production line of automobile brake caliper brackets". However, there are certain problems when conveying the brake caliper bracket through a conveyor belt. Since the brake caliper bracket is an irregular shape, it cannot be placed flat on the conveyor belt, so the brake caliper bracket placed on the conveyor belt is in an inclined state and is arranged in a disordered manner, which is very inconvenient for the manipulator to grab, so the production efficiency is low. If disordered grabbing is to be achieved, it is inevitable that the production cost will be greatly increased.

[0004] Therefore, the feeding device of the existing automatic production line of the brake caliper bracket needs to be further improved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a feeding device for an automated production line of a brake caliper bracket, which is convenient for subsequent robot arms to grasp and effectively improves production efficiency, in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a feeding device for an automated production line of a brake caliper bracket, comprising: a fixed bracket; a workpiece conveying mechanism, comprising at least one group of chain conveying assemblies for placing the brake caliper bracket, the chain conveying assembly is arranged on the fixed bracket and can convey the brake caliper bracket placed on the chain conveying assembly from the first end to the second end; the chain conveying assembly includes two parallel conveying chains, and two symmetrically arranged shelf grooves at the bottom of the brake caliper bracket can be respectively matched on the two conveying chains; the spacing between the two conveying chains is consistent with the distance between the two shelf grooves of the brake caliper bracket.

[0007] In order to drive the two conveying chains to move synchronously and thereby transfer the brake caliper bracket from the first end to the second end of the chain conveying assembly, the workpiece conveying mechanism also includes a chain driving device capable of driving the two conveying chains in the chain conveying assembly to move synchronously; the chain conveying assembly includes two chain support frames, each of which has a sprocket that can rotate freely at both ends, and the conveying chain is mounted on the sprockets at both ends of the chain support frames, wherein the chain driving device can drive the corresponding sprockets on the two chain support frames to move synchronously.

[0008] In order to prevent the brake caliper bracket from jumping during the conveying process, a pressing rod assembly is also provided above the chain conveying assembly. The pressing rod assembly includes a first suspension and a pressing rod movably connected to the first suspension up and down. The extension direction of the pressing rod is consistent with the length direction of the chain conveying assembly.

[0009] Due to the structural characteristics of the brake caliper bracket itself, adjacent brake caliper brackets are arranged closely during the conveying process, which is very inconvenient for the robot to grab the workpiece, so the end brake caliper bracket needs to be separated from the adjacent brake caliper bracket in time to facilitate the robot to clamp the workpiece, and also includes a workpiece separation mechanism arranged at the second end position of the chain conveying assembly, the workpiece separation mechanism includes: a reverse pushing assembly, arranged in front of the second end of the chain conveying assembly, including a pushing piece that can reciprocate along the length direction of the chain conveying assembly, and the pushing piece can push the front end brake caliper bracket on the chain conveying assembly in the opposite direction to the first set position when it extends backward; a blocking assembly, including a blocking piece that can reciprocate toward the direction of the chain conveying assembly, when the reverse pushing assembly pushes the front end brake caliper bracket on the chain conveying assembly in the opposite direction to the first set position, the blocking piece extends to block other brake caliper brackets except the front end brake caliper bracket from staying in the original position.

[0010] In order to facilitate the reasonable arrangement of the various components of the workpiece separation mechanism, the material blocking member is arranged above the second end of the chain conveying assembly and can reciprocate in the up and down directions; the material blocking assembly also includes a second suspension arranged on the fixed bracket, and the second suspension is connected to a first driving device for driving the material blocking member to reciprocate.

[0011] Preferably, the reverse pushing assembly further comprises a front bracket arranged on the fixed bracket, and a second driving device for driving the pushing member to reciprocate is connected to the front bracket.

[0012] Since the distances between the two resting grooves of brake caliper brackets of different specifications are also different, in order to realize the transportation of brake caliper brackets of different specifications, a chain width adjustment mechanism for adjusting the distance between the two conveying chains in the chain conveying assembly is also provided on the fixed bracket.

[0013] In order to be able to flexibly and quickly adjust the distance between the two conveying chains, the chain width adjustment mechanism includes at least two groups of slide rail support assemblies arranged at intervals along the length direction of the conveying chain, each group of slide rail support assemblies includes a slide rail arranged on the fixed bracket and two slide seats slidably arranged on the slide rail, and each group of slide rail support assemblies is also correspondingly provided with a locking mechanism for limiting the two slide seats at preset positions on the slide rail; wherein, the slide rail is arranged along the width direction of the chain conveying assembly, and the two chain support frames are respectively connected to the two slide seats and can move away from or approach each other as the two slide seats slide.

[0014] In order to make the adjustment accuracy of the distance between the two conveying chains higher, the locking mechanism includes a standard block structure arranged between the two slides and two clamping components arranged on the outside of the two slides. The standard block structure can cooperate with the two clamping components to separate the two slides arranged on the slide rail and limit them to a preset position.

[0015] As an improvement, the standard block structure includes a first fixed seat mounted above the slide rail and a standard block detachably connected to the first fixed seat; the clamping assembly includes a second fixed seat mounted above the slide rail, and the second fixed seat is provided with an adjustment screw that can be screwed in along the length direction of the slide rail.

[0016] Compared with the prior art, the advantages of the present invention are that the feeding device of the automated production line of the brake caliper bracket in the present invention conveys the brake caliper bracket by means of two conveying chains, wherein the two conveying chains can respectively fit in two symmetrically arranged shelf grooves at the bottom of the brake caliper bracket, and the spacing between the two conveying chains is consistent with the distance between the two shelf grooves of the brake caliper bracket, so that the brake caliper bracket can be stably arranged on the conveying chain to realize orderly conveying of the workpiece, which greatly facilitates the subsequent robot to grasp at the second end of the chain conveying assembly, and effectively improves the feeding efficiency.

[0031] The present invention is further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-Figure 3 The structure of the automobile brake caliper bracket 1 is an irregular special-shaped body, specifically including a bracket body 1a, side portions 1b extending backwards on both sides of the bottom of the bracket body 1a, and protrusions 1c protruding forwards on both sides of the upper part of the bracket body 1a, wherein the bracket body 1a is an irregular, approximately bridge-shaped plate with two ends facing downwards and the middle facing upwards compared to the two ends. Specifically, the bottom of the brake caliper bracket 1 has two symmetrical shelf grooves 100, and the extension direction of the two shelf grooves 100 is consistent with the extension direction of the two side portions 1b of the brake caliper bracket 1.

[0033] See also Figure 1-Figure 14 The feeding device of the automatic production line of the brake caliper bracket includes a fixed bracket 10, a workpiece conveying mechanism, a pressure rod assembly 30, a workpiece separation mechanism and a chain width adjustment mechanism, wherein the workpiece conveying mechanism includes at least one group of chain conveying assemblies 20 for placing the brake caliper bracket 1, the chain conveying assembly 20 is arranged on the fixed bracket 10 and can convey the brake caliper bracket 1 placed on the chain conveying assembly 20 from the first end to the second end; the pressure rod assembly 30 is correspondingly arranged above the chain conveying assembly 20 to prevent the brake caliper bracket from jumping during the conveying process, so as to realize the stable and orderly conveying of the brake caliper bracket; the workpiece separation mechanism is arranged at the second end position of the chain conveying assembly 20, and is used to separate the front end of the brake caliper bracket conveyed to the second end of the chain conveying assembly 20 so that the subsequent manipulator (not shown) can perform a clamping action; the chain width adjustment mechanism is used to adjust the distance between the two conveying chains 21 in the chain conveying assembly 20, so as to facilitate the conveying of brake caliper brackets of different specifications.

[0034] See also Figure 4-Figure 6In this embodiment, the workpiece conveying mechanism includes two groups of chain conveying assemblies 20, which are placed side by side on the fixed bracket 10, wherein each group of chain conveying assemblies 20 includes two parallel conveying chains 21, and two symmetrically arranged shelf grooves 100 at the bottom of the brake caliper bracket 1 can be respectively matched on the two conveying chains 21. Specifically, the spacing between the two conveying chains 21 is consistent with the distance between the two shelf grooves 100 of the brake caliper bracket. Such a structural setting can make the two shelf grooves 100 of the brake caliper bracket just limited on the two conveying chains 21. During the conveying process, the brake caliper bracket will not have left-right deviation or front-back tilt problems, thereby facilitating the precise grasping of the manipulator.

[0035] Continue to see Figure 4-Figure 6 The chain conveying assembly 20 includes two chain support frames 22, and each of the two ends of the chain support frame 22 is provided with a sprocket 23 that can rotate freely. The conveying chain 21 is assembled on the sprockets 23 at both ends of the chain support frame 22. Specifically, the chain support frame 22 is a strip box body, and the two sprockets 23 are assembled at both ends of the strip box body, wherein the conveying chain 21 assembled on the two sprockets 23 is divided into an upper and lower layer. Specifically, the upper layer of the conveying chain 21 is exposed to the strip box body, and the lower layer is contained in the strip box body to prevent foreign objects from touching the conveying chain 21. In addition, in order to prevent the conveying chain 21 from bending after being placed on the brake caliper bracket 1 and preventing the workpiece from being smoothly transported, two chain support bars 24 for supporting the conveying chain 21 are fixed on the upper and lower walls of the strip box body, wherein the chain support bars 24 can be made of wear-resistant material. Specifically, the two chain support bars 24 are arranged side by side up and down, and both extend from the sprocket 23 at one end of the strip box body to the sprocket 23 position at the other end. More specifically, the two chain support bars 24 are connected to the upper and lower walls of the strip box body by screws. In this embodiment, at least the chain support bar 24 located on the upper layer of the strip box body is also provided with a strip-shaped limiting groove 241 for placing the transmission chain, so as to prevent the conveying chain 21 from detaching from the chain support bar 24 during the transmission process, see for details. Figure 10-13 .

[0036] See also Figure 6In order to drive the two conveying chains 21 to move synchronously, and then transfer the brake caliper bracket from the first end of the chain conveying assembly 20 to the second end, the workpiece conveying mechanism also includes a chain driving device, which is used to drive the two conveying chains 21 in the chain conveying assembly 20 to move synchronously. In this embodiment, the chain driving device is arranged at the second end of the chain conveying assembly 20. Specifically, the chain driving device includes a driving motor 25 arranged on the fixed bracket 10, and the driving motor 25 is connected to the chain support frame 22 through a gear transmission device. Sprockets 23, wherein one end of the shaft 231 of each sprocket 23 is also provided with a first driving gear 232 for driving the sprocket 23 to rotate coaxially, and the first driving gear 232 is located on the outside of the strip box body. Accordingly, the gear transmission device includes a transmission shaft 26 arranged along the width direction of the chain transmission assembly 20, and the transmission shaft 26 is provided with a plurality of second driving gears 27 that can rotate coaxially with the transmission shaft 26 at intervals along its axial direction, wherein each second driving gear 27 is meshed with the first driving gear 232 of the corresponding sprocket 23.

[0037] See also Figure 5 and Fig. 9 The press rod assembly 30 includes a first suspension 31 and a press rod 32 movably connected to the first suspension 31 up and down. The extension direction of the press rod 32 is consistent with the length direction of the chain conveying assembly 20. Specifically, a press rod 32 is correspondingly provided above each chain conveying assembly 20. Since two groups of chain conveying assemblies 20 are provided on the fixed bracket 10 in this embodiment, two press rods 32 are correspondingly provided, and the two press rods 32 are connected to the same first suspension 31. The height of the press rod 32 in this embodiment is adjusted by a lifting adjustment mechanism 33, wherein the lifting adjustment mechanism 33 includes a hand wheel 331, a screw rod 332 and a screw rod sleeve 333, the screw rod 332 is arranged on the first suspension 31, the upper end of the screw rod 332 is connected to the hand wheel 331, the lower end of the screw rod 332 is threadedly connected to the screw rod sleeve 333, the press rod 32 is connected to the bottom end of the screw rod sleeve 333, when the hand wheel 331 is turned, the screw rod sleeve 333 can drive the press rod 32 to move up and down relative to the screw rod 332. In this embodiment, in order to make the press rod 32 more firmly fixed, the first suspension 31 is three, which are spaced apart along the length direction of the fixed bracket 10, and accordingly, the lifting adjustment mechanism 33 is three groups, which are respectively arranged on the three first suspensions 31.

[0038] See also Figure 3 Due to the structural characteristics of the brake caliper bracket itself, the adjacent brake caliper brackets are arranged closely during the conveying process, which is very inconvenient for the robot to grasp the workpiece, as shown in Figure 3In the process of conveying, the side portion 1b of the brake caliper bracket extending backwards overlaps with the protrusion 1c of another brake caliper bracket protruding forwards at the rear and adjacent to it in the vertical direction. During the grasping process of the robot, interference between the two adjacent brake calipers is inevitable, so the end brake caliper bracket needs to be separated from the adjacent brake caliper bracket in time to facilitate the robot to clamp. The workpiece separation mechanism in this embodiment is arranged in front of the second end of the chain conveying assembly 20. Specifically, the workpiece separation mechanism includes a reverse pushing assembly 41 and a blocking assembly 42, wherein the reverse pushing assembly 41 and the blocking assembly 42 can cooperate with each other to separate the front end brake caliper bracket 1 conveyed to the second end of the chain conveying assembly 20 so that the subsequent robot can perform a clamping action. For details, see Figure 4 and Figure 5 .

[0039] See also Figure 5 The reverse push assembly 41 includes a front bracket 412, a second driving device 413 and a push piece 411, wherein the front bracket 412 is arranged on the fixed bracket 10, specifically located in front of the second end of the chain transmission assembly 20, and the second driving device 413 is arranged on the front bracket 412, and is used to drive the push piece 411 to reciprocate. In this embodiment, the second driving device 413 is a cylinder, and the push piece 411 is a push plate connected to the piston rod of the cylinder, wherein, under the drive of the cylinder, the push piece 411 can extend backward to push the frontmost brake caliper bracket 1 on the chain transmission assembly 20 in the reverse direction to the first set position, and the push piece 411 can block the frontmost brake caliper bracket and stay in the second set position after resetting forward, and the second set position is located in front of the first set position. In this embodiment, the travel direction of the brake caliper bracket 1 is defined as "forward", and the direction opposite to the travel direction of the brake caliper bracket 1 is defined as "rear".

[0040] See also Figure 6The material stopper assembly 42 includes a material stopper 421 that can reciprocate toward the chain conveyor assembly 20. When the material pusher 411 pushes the frontmost brake caliper bracket 1 on the chain conveyor assembly 20 in the opposite direction to the first set position, the material stopper 421 extends to block the other brake caliper brackets except the frontmost brake caliper bracket and keep them in the original position. In order to facilitate the reasonable arrangement of the various components of the workpiece separation mechanism, the material stopper 421 is arranged above the second end of the chain conveyor assembly 20 and can reciprocate in the up and down directions; the material stopper assembly 42 also includes a second suspension 422 arranged on the fixed bracket 10, and the second suspension 422 is connected to a first driving device 423 for driving the material stopper 421 to reciprocate. In this embodiment, the first driving device 423 can be selected as a cylinder, and the material blocking member 421 is a material blocking plate connected to the piston rod of the cylinder, wherein, driven by the cylinder, the pushing plate can extend downward to block the corresponding brake caliper bracket 1 and keep it in the original position. Specifically, the brake caliper bracket 1 placed on the conveying chain 21 also has two inner groove openings 101 extending in the up and down directions, and the bottom of the pressing plate has two material blocking support arms 4211, which can be inserted into the two inner groove openings 101 of the brake caliper bracket 1.

[0041] See also Figure 5 In order to facilitate understanding of the technical solution of this embodiment, in this embodiment, the brake caliper bracket adjacent to the frontmost brake caliper bracket is defined as the second brake caliper bracket. When the frontmost brake caliper bracket is pushed in the reverse direction to the first set position, the stopper assembly 42 is just located above or on one side of the second brake caliper bracket, and when the stopper member 421 is extended under the drive of the second driving device 413, the second brake caliper bracket can be blocked, and when the second brake caliper bracket is blocked and stops moving forward, the brake caliper bracket located behind the second brake caliper bracket will also stay in the original position and cannot move forward.

[0042] The action process of the workpiece separation mechanism in this embodiment is as follows: the conveying chain 21 in this embodiment is always in a continuous rotation state, and the brake caliper bracket 1 can be continuously conveyed from the first end to the second end. When the brake caliper bracket is conveyed to the second end, the reverse pushing component 41 starts to act. Specifically, the pushing member 411 is driven by the first driving device 423 to extend backward to push the front end brake caliper bracket on the conveying chain 21 in the opposite direction to the first set position, and then the blocking member 421 of the blocking assembly 42 starts to act. The blocking member 421 is driven by the second driving device 413 to extend downward to block the brake caliper bracket adjacent to the front end brake caliper bracket. At this time, all the brake caliper bracket workpieces except the front end brake caliper bracket on the conveying chain 21 are blocked and stay in the original position, and then the pushing member 4 11 resets forward to the initial position. At the same time, the brake caliper bracket at the front end of the conveying chain 21 can continue to move forward and separate from the adjacent brake caliper bracket until it moves to contact the push piece 411 again and is blocked and stops at the second set position. The manipulator can easily grab the brake caliper bracket 1 that stops at the second set position; when the brake caliper bracket at the second set position is grabbed, the baffle plate can reset upward to release the brake caliper bracket. At this time, the previously blocked brake caliper bracket can continue to move forward with the conveying chain 21, and the reverse pushing assembly 41 is activated again to push the brake caliper bracket at the front end of the conveying chain 21 in the opposite direction to the first set position again, and then the baffle 421 of the baffle assembly 42 is activated again, and this cycle is repeated to complete the workpiece separation operation of the brake caliper bracket. In this embodiment, the second set position and the first set position of the front end brake caliper bracket are defined by the initial position and the end position before and after the action of the push piece 411. For details, see Figure 5 and Figure 6 Of course, it is conceivable that the second set position of the frontmost brake caliper bracket does not need to be limited by the initial position before the pusher 411 is actuated. For example, the second set position can also be limited by other limiting and stopping components. For example, a fixed stop block provided on the fixed bracket 10 can be used to block the frontmost brake caliper bracket and limit it to the second set position.

[0043] See also Figure 8-Figure 14Since the distance between the two resting grooves 100 of brake caliper brackets of different specifications is also different, in order to realize the transportation of brake caliper brackets of different specifications, a chain width adjustment mechanism for adjusting the spacing between the two conveying chains 21 in the chain conveying assembly 20 is also provided on the fixed bracket 10. Specifically, the chain width adjustment mechanism includes at least two groups of slide rail support assemblies 50 arranged at intervals along the length direction of the conveying chain 21. Each group of slide rail support assemblies 50 includes a slide rail 51 arranged on the fixed bracket 10 and two slide seats 52 slidably arranged on the slide rail 51. Each group of slide rail support assemblies 50 is also correspondingly provided with a locking mechanism for limiting the two slide seats 52 at a preset position of the slide rail 51. More specifically, the slide rail 51 is arranged along the width direction of the chain conveying assembly 20, that is, the extension direction of the slide rail is perpendicular to the length direction of the chain conveying assembly 20. The two chain support frames 22 are respectively connected to the two slide seats 52 and can move away from or approach each other as the two slide seats 52 slide. In this embodiment, the two conveyor chains 21 are independently connected to two slide seats 52 provided on the slide rail 51 through two chain support frames 22. When the distance between the two conveyor chains 21 needs to be adjusted, flexible and rapid adjustment can be achieved through the movement of the two slide seats 52.

[0044] In order to make the adjustment accuracy of the distance between the two conveying chains 21 higher, the locking mechanism includes a standard block structure 53 arranged between the two slides 52 and two clamping assemblies 54 arranged on the outside of the two slides 52. The standard block structure 53 can cooperate with the two clamping assemblies 54 to separate the two slides 52 arranged on the slide rail 51 and limit them to a preset position. More specifically, the standard block structure 53 includes a first fixed seat 531 mounted above the slide rail 51 and a standard block 532 detachably connected to the first fixed seat 531, wherein the sizes of different standard blocks 532 are adapted to the widths of brake caliper brackets of different specifications (specifically, the distance between the two resting grooves 100 at the bottom of the brake caliper bracket); the clamping assembly 54 includes a second fixed seat 541 mounted above the slide rail 51, and the second fixed seat 541 is provided with an adjustment screw 542 that can be screwed in along the length direction of the slide rail 51, see for details. Fig.14 .

[0045] In order to transport brake caliper brackets of different specifications, when the spacing between the two conveyor chains 21 needs to be adjusted, the adjusting screw 542 on the second fixed seat 541 can be loosened first, and then the previous standard block 532 can be removed from the first fixed seat 531, so that the two slides 52 can slide and adjust on the slide rail 51, and then another standard block 532 of a suitable size is replaced. After the standard block 532 is assembled, the adjusting screw 542 on the second fixed seat 541 is tightened, and the slide (chain support frame 22) is locked on the slide rail 51. This chain width adjustment mechanism has a simple structure and is easy to adjust, and can quickly and effectively achieve the spacing between two conveyor chains 21 in a set of chain conveyor components 20.

[0046] The feeding device of the automated production line of the brake caliper bracket in this embodiment has multiple advantages: first, the feeding device conveys the brake caliper bracket 1 through two conveying chains 21, wherein the two symmetrically arranged shelf grooves 100 at the bottom of the brake caliper bracket 1 can be respectively matched on the two conveying chains 21, and the spacing between the two conveying chains 21 is consistent with the distance between the two shelf grooves 100 of the brake caliper bracket, so that the brake caliper bracket can be smoothly arranged on the conveying chain 21 to realize the orderly conveying of the workpiece, which greatly facilitates the subsequent manipulator to grab at the second end of the chain conveying assembly 20, effectively improving the feeding efficiency. Efficiency; secondly, the workpiece separation mechanism of the feeding device includes a reverse pushing component 41 and a blocking component 42, wherein the reverse pushing component 41 and the blocking component 42 can cooperate with each other to separate the front end brake caliper bracket transmitted to the second end of the chain conveying component 20, so as to avoid interference of the adjacent brake caliper bracket with the grasping of the front end brake caliper bracket, thereby effectively improving the feeding efficiency of the automated production line of the brake caliper bracket; furthermore, the chain width adjustment mechanism of the feeding device can quickly and accurately adjust the distance between the two conveying chains 21 in the chain conveying component 20, thereby realizing the conveying operation of brake caliper brackets of different specifications.
