Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of riding drawer accessories, and in particular to a base feeding device for connecting locks. Background Technology

[0002] Currently, various connection structures between the drawer and the panel have appeared on the market. For example, Chinese Patent CN207228829U discloses a panel unlocking mechanism for a drawer, which discloses an upper connector and a lower connector. To enhance its structural strength, such connectors have been found on the market, as shown in the attached figure. Figure 1 The connection structure shown includes a base 600 and a latch 601. During assembly, the base 600 is loaded first and then the latch 601 is installed after the base is loaded to the corresponding work station.

[0003] for Figure 1 This elongated base 600 has two locking buckles 601. To accommodate the subsequent installation of the saddle blanket, the two locking buckles 601 are not symmetrically positioned around the center of the base 600. Therefore, after reserving the mounting slots 603 for the locking buckles 601, the front end of the base 600 is longer than the rear end. Since the material orientation is uncertain when feeding via a vibratory feeder, it is necessary to distinguish between the front and rear ends when feeding the base 600. Currently, the distinction between the front and rear ends when feeding this type of base 600 is mainly done manually, resulting in low efficiency. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a base feeding device for connecting locks to solve the above problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a base feeding device for connecting locks, including a vibratory feeder conveyor, front and rear end detection modules and a clamping robot, wherein the clamping robot is used to clamp the base and to move between the end of the vibratory feeder conveyor and the front and rear end detection modules.

[0006] The front and rear detection module includes a first support frame and a second support frame for supporting the front and rear ends of the base. The first support frame has a first placement slot for placing the base and a beam channel that penetrates through the frame and communicates with the first placement slot. A laser emitter is provided at one end of the beam channel and a laser receiver is provided at the other end of the beam channel. When the front end of the base is placed in the first placement slot, the front end of the base blocks the laser beam emitted by the laser emitter. When the rear end of the base is placed in the first placement slot, the laser beam emitted by the laser emitter passes through the mounting slot of the base near its own rear end and then illuminates the laser receiver.

[0007] It is worth noting that the front and rear end detection module also includes a lifting and rotating assembly disposed between the first support frame and the second support frame. The lifting and rotating assembly includes a first lifting cylinder, a first rotating cylinder and a rotating base. The telescopic shaft of the first lifting cylinder is vertically upward, the cylinder body of the first rotating cylinder is fixedly connected to the telescopic shaft of the first lifting cylinder, and the rotating output end of the first rotating cylinder is connected to the rotating base.

[0008] Preferably, the rotating base has a rotating placement groove, and when the first lifting cylinder and the first rotating cylinder are stationary, the rotating placement groove is located directly below the base of the first support frame and the second support frame.

[0009] Optionally, it also includes left and right side detection modules, which include a support frame assembly for supporting the base, and the support frame assembly has an avoidance recess at the end where the base is placed.

[0010] A linear drive mechanism and a proximity switch are provided on one side of the avoidance recess. The telescopic shaft of the linear drive mechanism is provided with a connecting block. An insertion block is provided at one end of the connecting block near the avoidance recess. The insertion block includes a rectangular column and a cylindrical member connected in sequence toward the avoidance recess.

[0011] The detection end of the proximity switch faces the clearance recess to detect whether the rectangular column is inserted into the mounting port of the base.

[0012] The gripping robot is used to move between the end of the vibratory feeder conveyor, the front and rear end detection modules, and the left and right side detection modules.

[0013] Specifically, it also includes a base flipping module, which includes a second lifting cylinder, a second rotating cylinder, a finger cylinder, and two third support frames. The third support frames are used to support the front and rear ends of the base. The second lifting cylinder is disposed on one side of one of the third support frames. The telescopic shaft of the second lifting cylinder is vertically upward and fixedly connected to the cylinder body of the second rotating cylinder. The rotating output end of the second rotating cylinder is fixedly connected to the cylinder body of the finger cylinder. The finger gripper of the finger cylinder faces the end of the base placed on the third support frame.

[0014] The gripping robot is used to move between the end of the vibratory feeder conveyor, the front and rear end detection modules, the left and right side detection modules, and the base flipping module.

[0015] It is worth noting that the base flipping module also includes a lifting cylinder, which is located below another third support frame away from the second lifting cylinder. The telescopic shaft of the lifting cylinder is vertically upward and fixedly connected to the third support frame.

[0016] The beneficial effects of this invention are as follows: In the base feeding device for connecting the latch, since the distance between the first support frame and the second support frame remains constant, after the base is placed on the first and second support frames, because the front end of the base is longer than the rear end, the position of the mounting slot corresponding to the front end will be closer to the center of the base than the position of the mounting slot corresponding to the rear end. Based on this principle, the emitting end of the laser emitter is aligned with the rearmost end of the mounting slot corresponding to the rear end of the placed base, allowing the laser beam to pass through the mounting slot and irradiate the laser receiver. If the base is placed on the first and second support frames with its front and rear ends reversed, the emitting end of the laser emitter can only be aligned with the front end of the base, preventing the laser beam from irradiating the laser receiver. Thus, by whether the laser receiver can receive the laser beam, it is possible to distinguish whether the end of the base closest to the laser emitter is the front or rear end, improving efficiency compared to manual judgment.

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1-10As shown, a base feeding device for connecting a locking buckle includes a vibratory feeder conveyor 1, front and rear end detection modules 2, and a clamping robot. The clamping robot is used to clamp the base 600 and to move between the end of the vibratory feeder conveyor 1 and the front and rear end detection modules 2. In this solution, the clamping robot is a conventional structure.

[0030] like Figure 3-5 As shown, the front and rear detection module 2 includes a first support frame 21 and a second support frame 22 for supporting the front and rear ends of the base 600. The first support frame 21 has a first placement slot 211 for placing the base 600. The first support frame 21 has a beam channel that penetrates its frame and is connected to the first placement slot 211. A laser emitter 23 is provided at one end of the beam channel and a laser receiver 24 is provided at the other end of the beam channel. When the front end of the base 600 is placed in the first placement slot 211, the front end of the base 600 blocks the laser beam 231 emitted by the laser emitter 23. When the rear end of the base 600 is placed in the first placement slot 211, the laser beam 231 emitted by the laser emitter 23 passes through the mounting slot 603 near the rear end of the base 600 and then irradiates the laser receiver 24.

[0031] In the base loading device for connecting the latch, since the distance between the first support frame 21 and the second support frame 22 remains constant, after the base 600 is placed on the first support frame 21 and the second support frame 22, because the front end of the base 600 is longer than the rear end, the position of the mounting groove 603 corresponding to the front end will be closer to the center of the base 600 than the position of the mounting groove 603 corresponding to the rear end. Based on this principle, the emitting end of the laser emitter 23 is aligned with the rearmost end of the mounting groove 603 corresponding to the rear end of the positioned base 600, so that the laser beam 231 passes through the mounting groove 603 and irradiates the laser receiver 24. If the base 600 is placed on the first support frame 21 and the second support frame 22 with its front and rear ends reversed, the emitting end of the laser emitter 23 can only be aligned with the front end of the base 600, so that the laser beam 231 cannot irradiate the laser receiver 24. Thus, by whether the laser receiver 24 receives the laser beam 231, it can be determined whether the end of the base 600 closest to the laser emitter 23 is the front or rear end, improving efficiency compared to manual judgment.

[0032] It is worth noting that, such as Figure 3 and 6As shown, the front and rear end detection module 2 further includes a lifting and rotating assembly 25 disposed between the first support frame 21 and the second support frame 22. The lifting and rotating assembly 25 includes a first lifting cylinder 251, a first rotating cylinder 252 and a rotating base 253. The telescopic shaft of the first lifting cylinder 251 is vertically upward. The cylinder body of the first rotating cylinder 252 is fixedly connected to the telescopic shaft of the first lifting cylinder 251. The rotating output end of the first rotating cylinder 252 is connected to the rotating base 253.

[0033] When the laser receiver 24 fails to receive the laser beam 231 emitted by the laser emitter 23, the first lifting cylinder 251 is activated, which drives the rotating base 253 to rise through the first rotating cylinder 252, thereby lifting the base 600 located on the first support frame 21 and the second support frame 22. Then, the first rotating cylinder 252 is activated, causing the base 600 to rotate 180°. After that, the first lifting cylinder 251 drives the rotating base 253 to descend, thereby placing the base 600 back on the first support frame 21 and the second support frame 22. At this time, if the laser emitter 23 emits the laser beam 231 again, the laser receiver 24 will be able to receive the laser beam 231.

[0034] Preferred, such as Figure 6 As shown, the rotating base 253 has a rotating placement groove 254. When the first lifting cylinder 251 and the first rotating cylinder 252 are stationary, the rotating placement groove 254 is located directly below the base 600 placed on the first support frame 21 and the second support frame 22. By providing the rotating placement groove 254, when the rotating base 253 is lifted, the base 600 can be inserted into the rotating placement groove 254 and rotate 180° under the drive of the rotating base 253, and it is not easy to detach from the rotating base 253.

[0035] Optional, such as Figure 3 and 7 As shown, it also includes left and right side detection modules 3. The left and right side detection modules 3 include a support frame assembly 31 for supporting the base 600. The support frame assembly 31 has an avoidance recess 311 at the end where the base 600 is placed, so that the mounting port 602 at the end of the base 600 is exposed, which facilitates subsequent detection.

[0036] A linear drive mechanism 32 and a proximity switch 35 are provided on one side of the avoidance recess 311. The telescopic shaft of the linear drive mechanism 32 is provided with a connecting block 33. An insertion block 34 is provided at one end of the connecting block 33 near the avoidance recess 311. The insertion block 34 includes a rectangular column member 341 and a cylindrical member 342 connected in sequence in the direction of approaching the avoidance recess 311.

[0037] The detection end of the proximity switch 35 faces the avoidance recess 311 to detect whether the rectangular column member 341 is inserted into the mounting port 602 of the base 600.

[0038] The gripping robot is used to move between the end of the vibratory feeder conveyor 1, the front and rear end detection modules 2, and the left and right side detection modules 3.

[0039] for Figure 1 and Figure 10 The base 600, designed to accommodate the subsequent installation of the saddle blanket, has a mounting opening 602 with a rectangular cross-section on the left and a circular cross-section on the right. This necessitates distinguishing between the left and right sides when loading the base 600; only then can the locking buckle 601 be assembled into the correct position in subsequent processes. Currently, distinguishing the left and right sides during loading of this base 600 is primarily done manually, resulting in low efficiency. Thus, in the linear drive mechanism 32, under the action of the cylinder, the connecting block 33 moves towards the avoidance recess 311. When the connecting block 33 drives the insertion block 34 towards the avoidance recess 311, if the base 600 is positioned with the left side of the rectangular cross-section of the mounting opening 602 facing the insertion block 34, the insertion block 34 can be fully inserted into the mounting opening 602. If the base 600 is positioned with the right side of the circular cross-section of the mounting opening 602 facing the insertion block 34, only the cylindrical part 342 of the insertion block 34 can be inserted into the mounting opening 602. The stroke of the connecting block 33 is different in the two cases. By detecting whether the connecting block 33 is close, these two cases can be identified. In both cases, when the insertion block 34 is fully inserted into the mounting opening 602, the connecting block 33 is closer to the proximity switch 35, and can be detected by the proximity switch 35.

[0040] Specifically, such as Figure 3 and 8 As shown, it also includes a base flipping module 4, which includes a second lifting cylinder 42, a second rotating cylinder 43, a finger cylinder 44, and two third support frames 41. The third support frames 41 are used to support the front and rear ends of the base 600. The second lifting cylinder 42 is disposed on one side of one of the third support frames 41. The telescopic shaft of the second lifting cylinder 42 is vertically upward and fixedly connected to the cylinder body of the second rotating cylinder 43. The rotation output end of the second rotating cylinder 43 is fixedly connected to the cylinder body of the finger cylinder 44. The finger gripper of the finger cylinder 44 faces the end of the base 600 placed on the third support frame 41.

[0041] The gripping robot is used to move between the end of the vibratory feeder conveyor 1, the front and rear end detection modules 2, the left and right side detection modules 3, and the base flipping module 4.

[0042] When the left and right side detection module 3 detects that the placement orientation of the left and right sides of the base 600 is inconsistent with the rated orientation, the gripping robot moves the base 600 to the third support frame 41 of the base flipping module 4. Then, the finger cylinder 44 actuates, clamping the end of the base 600 with its own finger gripper. Next, the second lifting cylinder 42 actuates, driving the second rotating cylinder 43 and the finger cylinder 44 to lift synchronously. Finally, the second rotating cylinder 43 drives the finger cylinder 44 to rotate 180°, reversing the placement orientation of the left and right sides. After completion, the second lifting cylinder 42 descends, and the finger gripper of the finger cylinder 44 releases the base 600.

[0043] It is worth noting that, such as Figure 3 and 9 As shown, the base flipping module 4 also includes a lifting cylinder 45, which is located below another third support frame 41 away from the second lifting cylinder 42. The telescopic shaft of the lifting cylinder 45 is vertically upward and fixedly connected to the third support frame 41.

[0044] During the lifting process of the second lifting cylinder 42, in order to prevent the other end of the base 600 not being held by the finger cylinder 44 from swinging downward, the lifting cylinder 45 will also move synchronously with the second lifting cylinder 42, driving the other third support frame 41 to rise, thereby keeping the base 600 balanced. Before the second rotating cylinder 43 rotates, the lifting cylinder 45 will first drive the other third support frame 41 to fall. After the second rotating cylinder 43 rotates, the lifting cylinder 45 will drive the other third support frame 41 to rise, thereby re-supporting the other end of the base 600.

[0045] The base feeding device for connecting the latch in this solution is suitable for... Figure 1 and Figure 10 The two bases shown are 600, for Figure 10 The base 600 shown has a centered locking buckle 601 to accommodate the subsequent installation of the saddlebag. Therefore, the front and rear ends of the base 600 are of the same length. Figure 10 When loading the base 600, it is not necessary to distinguish between the front and rear ends; only the left and right sides of the mounting port 602 need to be distinguished. However, Figure 1 and Figure 10 The two 600 bases shown are for different models of riding drawers, therefore Figure 1 and Figure 10The two types of bases 600 shown have different rear end lengths. Furthermore, when loading the base 600, the loading device uses the end of the base 600 as the reference surface. However, after loading, when installing the latch 601, the corresponding latch installation device uses the mounting groove 603 of the latch 601 as the reference surface. Therefore, before the base 600 is conveyed to the latch installation device, an alignment process is required to ensure that the loading device, whether loading or not, achieves the correct alignment. Figure 1 The base is 600 or Figure 2 The base 600 and the mounting slot 603 are all positioned uniformly. Therefore, as Figure 9 As shown, the base feeding device for connecting the latch also includes an alignment module 5. The alignment module 5 includes a fourth support frame 51 for placing the base 600. The fourth support frame 51 has an alignment recess 511. An alignment translation cylinder 52 is provided on one side of the alignment recess 511. The telescopic end of the alignment translation cylinder 52 faces the rear end of the base 600 placed in the alignment recess 511, so as to... Figure 1 The rear end of the base 600 shown is pushed away from the alignment translation cylinder 52 by a predetermined stroke; the gripping manipulator is used to move between the end of the vibratory feeder conveyor 1, the front and rear end detection modules 2, the left and right side detection modules 3, the base flipping module 4 and the alignment module 5.

[0046] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
