Description

Technical Field

[0001] This utility model relates to the field of gripper technology, specifically to a gripper for assembly transfer in an automotive electric drive assembly production line. Background Technology

[0002] In the electric drive assembly line, the workpiece is flipped and transferred manually using grippers, with KBK guide rails facilitating the transfer from the assembly line to the testing line. When compatibility with different electric drives is required, the grippers must be manually replaced, with the replacement grippers placed on a support. All work before this station's replacement must be done manually, resulting in high labor intensity, long processing time, and potential worker fatigue, increasing the risk of operational errors. The replaced grippers need to be properly stored for later use. However, under manual management, the storage, retrieval, and recording of grippers can become chaotic and difficult. Due to the limitations of manual operation, it is impossible to track and record the gripper replacement process. When product information needs to be traced, it is impossible to accurately determine when and which gripper was used at that station, making information correction impossible. While a Staubli quick-change mechanism can automatically switch grippers, current grippers are not easily positioned and stored to facilitate rapid gripper switching with the Staubli quick-change mechanism. Utility Model Content

[0003] This invention provides a gripper library for assembly transfer in automotive electric drive assembly production lines, which solves the technical problem in the prior art where grippers are not easy to position and store in order to facilitate automatic switching of different grippers by robots.

[0004] To solve the above problems, the assembly transfer clamping magazine for automotive electric drive assembly production lines provided by this utility model adopts the following technical solution:

[0005] The device includes a support assembly, with a connecting seat at the bottom and multiple sets of spaced-apart gripper magazines on the upper surface of the support assembly. These gripper magazines are used to store grippers of different structures.

[0006] Each set of gripper magazines includes two sets of detachable positioning pins distributed on the support assembly. One set of positioning pins has a detachable detection plate near the top, and the detection plate has a safety pin. The other set of positioning pins has a first sensor for detecting whether the gripper is in position. The distribution of the first sensor in each set of gripper magazines is different.

[0007] Furthermore, each set of locating pins includes two spaced apart, and the bottom end of each locating pin is provided with a flange for connection to the bracket assembly.

[0008] Furthermore, one of the positioning pins in one set has a diamond-shaped pin at its tip, and one of the positioning pins in the other set has a round pin at its tip, with the diamond-shaped pin and the round pin being diagonally distributed.

[0009] Furthermore, the first sensor is fixed to an L-shaped bracket, which is fixed to the top of a positioning pin by bolts.

[0010] Furthermore, the detection plate includes a first connecting plate and a second connecting plate. A groove is formed on one side of the first connecting plate, and the second connecting plate is bolted to the groove. The positioning pin is clamped between the first connecting plate and the second connecting plate.

[0011] Furthermore, the side of the slot opposite to the positioning pin and the side of the second connecting plate opposite to the positioning pin are both provided with arc-shaped grooves.

[0012] Furthermore, the first connecting plate is provided with a second sensor for detecting whether the gripper is placed horizontally.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting up multiple sets of gripper magazines for holding different types of grippers, the flexibility and adaptability of line transfers are improved. The first sensor in each set of gripper magazines is positioned differently, and different types of grippers are identified by triggering signals from the first sensor at different positions. The design of multiple gripper magazines allows for rapid switching between different grippers when transferring the electric drive assembly from the assembly line to the testing line, reducing gripper change time and downtime, and improving production efficiency.

[0015] 2. In this invention, by setting different spacing between each set of positioning pins, and by using diagonally placed diamond-shaped and round pins with specific shapes and sizes, which match the corresponding holes or slots on the grippers, this design ensures that the grippers can only be placed in the correct manner and position, thereby improving positioning accuracy.

[0016] 3. In this utility model, the circuit can only be triggered by the cooperation of the first sensor, the second sensor and the safety pin, so as to ensure the safe unlocking of the quick-change mechanism and prevent safety accidents caused by misoperation or unexpected situations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0027] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0028] An embodiment of the assembly transfer clamping magazine for automotive electric drive assembly production lines provided by this utility model:

[0029] like Figures 1 to 5 As shown,

[0030] It includes a support assembly 1, a connecting seat 2 is provided below the support assembly 1, and multiple sets of spaced gripper magazines 3 are provided on the upper surface of the support assembly 1. The multiple sets of gripper magazines 3 are used to store grippers with different structures.

[0031] By setting up multiple gripper libraries with different grippers, the flexibility and adaptability of line transitions on the production line are improved.

[0032] Each set of gripper magazines 3 includes two sets of detachable positioning pins 31 distributed on the support assembly 1. It should be noted that the back of the corresponding gripper is provided with a Staubli quick-change disc, and the front is provided with a placement block that mates with the positioning pins 31. The placement block has a slot corresponding to the positioning pins 31. When placing the gripper, the front of the gripper is facing down, so that the end of the positioning pin 31 is inserted into the placement block to achieve stable support.

[0033] One of the positioning pins 31 has a detachable detection plate 311 near the top, and the detection plate 311 is provided with a safety pin 312.

[0034] In this embodiment, the detection plate 311 includes a first connecting plate 311a and a second connecting plate 311b. A groove is formed on one side of the first connecting plate 311a, and the second connecting plate 311b is bolted to the groove. A positioning pin 311 is clamped between the first connecting plate 311a and the second connecting plate 311b. Arc-shaped grooves are provided on the side of the groove opposite to the positioning pin 311 and on the side of the second connecting plate 311b opposite to the positioning pin 311.

[0035] The detachable design of the detection plate 311 simplifies installation and maintenance. When the locating pin 31 needs replacement or repair, the detection plate 311 can be easily removed without the need for complex disassembly of the entire gripper magazine. This improves productivity and reduces maintenance costs.

[0036] It should be noted that a sensor safety lock that cooperates with the safety pin 312 is fixed on one side of the front of the gripper to be placed. When the safety pin 312 is inserted into the sensor safety lock 4, the safety circuit is triggered. With the comprehensive judgment of other sensors, the quick-change mechanism can be vented and unlocked, the quick-change disc robot is separated from the tool side, and the gripper is put into storage.

[0037] In this embodiment, each set of positioning pins 31 includes two spaced-apart pins, and the bottom end of each positioning pin 31 has a flange for connection with the bracket assembly 1. It should be noted that the spacing between the two positioning pins 31 in one set is different from the spacing between the two positioning pins 31 in the other set. By setting different spacings, the positioning of the gripper can be better assisted, avoiding situations such as inverted placement. This ensures that the gripper can be accurately aligned and stored in the predetermined position during placement. This design makes the placement of the gripper more precise, reducing errors and deviations caused by inaccurate positioning.

[0038] One of the locating pins 31 in one set has a diamond-shaped pin 314 at its tip, while the other locating pin 31 in the other set has a circular pin 315 at its tip. The diamond-shaped pin 314 and the circular pin 315 are diagonally distributed. The diamond-shaped pin 314 and the circular pin 315, placed diagonally, have specific shapes and sizes that match corresponding holes or slots on the grippers. This design ensures that the grippers are placed only in the correct manner and position, thereby improving positioning accuracy.

[0039] In this embodiment, another set of positioning pins 31 is provided with a first sensor 313 for detecting whether the gripper is in position, wherein the distribution of the first sensor 313 in each set of gripper magazines 3 is different.

[0040] Specifically, in this embodiment, the gripper magazine 3 consists of three groups. In the first group of gripper magazines 3, one first sensor 313 is located on the left positioning pin 31. In the second group of gripper magazines 3, one first sensor 313 is located on the right positioning pin 31. In the third group of gripper magazines 3, two first sensors 313 are located on the two positioning pins 31. The gripper is identified by the different positions of the first sensors 313. A signal from the left sensor indicates that gripper A is in the magazine, a signal from the right sensor indicates that gripper B is in the magazine, and simultaneous signals from both the left and right sensors indicate that gripper C is in the magazine.

[0041] In this embodiment, the first sensor 313 is fixed to the L-shaped bracket 316, which is bolted to the top of the positioning pin 31. Specifically, the first sensor 313 can be a contact-type position sensor, that is, when the gripper enters the storage compartment and contacts the corresponding first sensor 313, the first sensor 313 triggers a signal.

[0042] The first connecting plate 311a is equipped with a second sensor 311c for detecting whether the gripper is placed horizontally. Specifically, in this embodiment, the second sensor 311c can be a horizontal sensor.

[0043] In this embodiment, the assembly transfer gripper for automotive electric drive assembly production lines is used such that when the first sensor 313 detects the gripper entering the gripper and the second sensor 311c detects the gripper being placed horizontally, the gripper is determined to be in the gripper's storage state. Simultaneously, after the safety pin 312 is inserted into the sensor safety lock, the quick-change mechanism can be vented to unlock, separating the robot side and tool side of the quick-change tray, and the gripper is stored. This facilitates safe unlocking and replacement of the gripper.

[0044] The system utilizes first sensors 313 at different locations to distinguish between different grippers, and multiple gripper libraries 3 to buffer various grippers, improving the accuracy and reliability of gripper changes during line transitions. This enhances the overall performance and flexibility of the production line, and increases overall processing efficiency.
