[0022] The utility model aims to provide a wiper assembly auxiliary device, which can reduce the workload of workers when assembling bracket components and improve production efficiency. This auxiliary device mainly includes a plurality of limit fixtures and a turntable mechanism that allows several of the limit fixtures to circulate and rotate between several stations. This auxiliary device is designed with multiple stations, each station corresponds to a different assembly step, and includes the following assembly steps in sequence according to the assembly process: placing a secondary bracket; placing a main bracket; pressing the convex shaft of the secondary bracket into the bayonet of the main bracket; pressing the main bracket along the width direction of the bracket assembly; and transferring the finished bracket assembly to a bracket assembly collection area. Accordingly, this auxiliary device also includes a pressing mechanism for pressing the convex shaft of the secondary bracket into the bayonet of the main bracket, a clamping mechanism for transferring the bracket assembly, and a clamping mechanism for pressing the main bracket along the width direction of the bracket assembly.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and one of the embodiments of the present invention.

[0024] See also Figures 3 to 5 In one embodiment of the utility model, the wiper assembly auxiliary device provided by the utility model includes a machine platform 1, and a turntable mechanism is provided on the machine platform 1, and the turntable mechanism includes a turntable 2 and a first driving device for driving the turntable 2 to rotate. A pressing mechanism is also provided on the machine platform 1, and the pressing mechanism includes a first pressing block 31 and a second driving device 32, the first pressing block 31 is located above the turntable 2, and the second driving device 32 is used to drive the first pressing block 31 to move up and down.

[0025] Considering that the main bracket 100 is a metal part, in order to improve the width w of the bracket assembly (see Figure 1 ), a clamping mechanism is also provided on the machine 1, the clamping mechanism includes a second clamping block 41, a side plate 42 and a third driving device 43, and the third driving device 43 is used to drive the second clamping block 41 to move closer to and away from the side plate 42. In other embodiments of the utility model, the clamping mechanism may not be provided.

[0026] In order to save labor and improve efficiency, a support frame 5 is also provided on the machine 1. A guide rail 61 of a clamping mechanism is erected above the turntable 2 through the support frame 5. The clamping mechanism also includes a first clamping jaw 62, a second clamping jaw 63 and a fourth driving device 64. The fourth driving device 64 is connected to the second clamping jaw 62, and the second clamping jaw 62 is connected to the third clamping jaw 63, so that under the drive of the fourth driving device 64, the first clamping jaw 62 and the second clamping jaw 63 can be synchronously moved along the guide rail 61. In other embodiments of the utility model, the clamping mechanism may not be provided, and a worker is responsible for transferring the bracket assembly from the turntable to the clamping mechanism and from the clamping mechanism to the bracket assembly collection point. However, if the operation is improper, the clamping mechanism may pinch the hand; or, in the case of no clamping mechanism, a worker directly transfers the bracket assembly from the turntable to the bracket assembly collection point.

[0027] In order to solve the problem of placing the main bracket, the auxiliary bracket and the bracket assembly, the utility model specifically provides a limiting tool 7, see Figures 7A to 7D The limiting tooling 7 includes a base 71 and an intermediate limiting block 72, two first limiting blocks 73, two second limiting blocks 74, two third limiting blocks 75 and two fourth limiting blocks 76 arranged on the upper side of the base 71. The two first limiting blocks 73, the two second limiting blocks 74, the two third limiting blocks 75 and the two fourth limiting blocks 76 are respectively located on both sides of the intermediate limiting block 72, and the distances between the first limiting block 73, the second limiting block 74, the third limiting block 75 and the fourth limiting block 76 and the intermediate limiting block 72 increase successively.

[0028] The second limit block 74 and the third limit block 75 are provided with limit grooves for preventing the auxiliary bracket 200 from moving along the width direction w of the bracket assembly. The first limit block 73 and the fourth limit block 76 are used to prevent the auxiliary bracket 200 from moving along the length direction L of the bracket assembly (see Figure 1 ), the two third limit blocks 75 are used to prevent the main bracket 100 from moving along the length direction L of the bracket assembly, the middle limit block 72 is used to prevent the main bracket 100 from moving along the width direction w of the bracket assembly, and the base 71 is used to support the main bracket 100 and the auxiliary bracket 200 along the height direction h. By preventing the main bracket 100 and the auxiliary bracket 200 from moving along the length direction L and the width direction w of the bracket assembly, the convex shaft 211 can be accurately inserted into the corresponding bayonet 101.

[0029] The second limit block 74 is arranged near the connection between the convex shaft 211 and the bayonet 101, and the upper surface is matched with the main bracket 100, so as to support the main bracket 100 along the height direction h when the convex shaft 211 is pressed into the bayonet 101, so as to make the pressing process smoother. In other embodiments of the utility model, the first limit block 73 and / or the second limit block 74 and / or the third limit block 75 may not be provided. When the first limit block 73 is not provided, the structure of the middle limit block 72 is adjusted accordingly so that it can replace the first limit block 73 to limit the auxiliary bracket 200 along the length direction L of the bracket assembly; when the third limit block 75 is not provided, the structure of the middle limit block 72 is adjusted accordingly so that it can replace the third limit block 75 to limit the main bracket 100 along the length direction L of the bracket assembly; when the second limit block 74 is not provided, when the pressing mechanism applies pressure to the main bracket 100, the support of the limit fixture 7 to the main bracket 100 along the height direction h is weak.

[0030] A clearance groove 721 is provided on the upper side of the middle limit block 72 corresponding to the joint connecting shaft 102 of the main bracket 100. The clearance groove 721 is used to make way for the joint connecting shaft 102 of the main bracket 100. The clearance groove 721 includes a "\ / "-shaped guide section, which is used to guide the joint connecting shaft 102 when the main bracket 100 is placed on the limiting fixture 7, so that the process of placing the main bracket 100 on the limiting fixture 7 is smoother. In other embodiments of the utility model, the middle limit block can also be other structures, which can achieve the limitation of the main bracket 100 along the width direction w of the bracket assembly. When designing the limiting fixture 7, a fool-proof design is made for the placement direction of the main bracket 100 and the auxiliary bracket 200 (for example, the position of the upper limit grooves of the second limit block 74 and the third limit block 75 is not centered), which can prevent the main bracket 100 and the auxiliary bracket 200 from being placed upside down and causing assembly failure.

[0031] See also Figure 6, four limit fixtures 7 are arranged on the turntable 2, and the four limit fixtures 7 are arranged at intervals of 90° along the circumference of the turntable 2, corresponding to positions A to D respectively, and the pressing mechanism and the clamping mechanism are arranged at intervals of 90° along the circumference of the turntable 2. A limit fixture 7 is arranged between the second pressing block 41 and the side plate 42, corresponding to position E. The assembly process is as follows:

[0032] At station A, see Fig. 7A , a worker places two auxiliary brackets 200 on the limiting tooling 7 in a specific direction;

[0033] The turntable 2 rotates 90° in direction r, and the limit fixture 7 originally at station A rotates to station B. Figure 7B , another worker places a main bracket 100 on the limiting tooling 7 in a specific direction;

[0034] The turntable 2 rotates another 90° in direction r, and the limit fixture 7 originally at station B rotates to station C. Figure 7C , the pressing mechanism applies a downward pressure F to the main bracket 100 stacked on the two auxiliary brackets 200, so that the protruding shaft 211 is pressed into the corresponding bayonet 101;

[0035] The turntable 2 rotates another 90° in direction r, and the limit fixture 7 originally at station C rotates to station D. Fig.7D At this time, the main bracket 100 and the two auxiliary brackets 200 have been assembled together to form a bracket assembly in a semi-finished state;

[0036] The first clamp 62 transfers the semi-finished bracket assembly from the limiting tool 7 at the station D to the limiting tool 7 at the station E, and then the limiting tool 7 originally at the station D is rotated to the station A to enter the next cycle;

[0037] The main bracket 100 is a metal part. At the workstation E, the pressing mechanism presses the main bracket 100 of the semi-finished bracket assembly on the limiting fixture 7, so that the side wall of the main bracket 100 and the auxiliary bracket 200 are more closely fitted, and the semi-finished bracket assembly becomes a finished bracket assembly;

[0038] The second clamping jaw 63 transfers the finished bracket assembly from the work station E to the bracket assembly collection station F.

[0039] The wiper assembly auxiliary device also includes a control device, and the first drive device, the second drive device 32, the third drive device 43, the fourth drive device 64, the first clamping jaw 62 and the second clamping jaw 63 are controlled by the control device to implement the above process. The first drive device, the second drive device 32, the third drive device 43 and the fourth drive device 64 can be cylinders or motors.

[0040] See also Figure 6At the same time, (1) the worker at station A places the auxiliary support 200 on the limiting fixture 7, (2) the worker at station B places the main support 100 on the limiting fixture 7, (3) the pressing mechanism at station C assembles the main support 100 and the auxiliary support 200 together, (4) the first clamp 62 at station D transfers the semi-finished support assembly to station E, and (5) the second clamp 63 at station E transfers the finished support assembly to the support assembly collection point F. These five steps are parallel. The control device only needs to rotate the turntable 2 by 90° every short period of time, and at the same time, the gripping mechanism performs a combination action of the gripping jaw descending and grabbing + the gripping jaw rising and moving forward + the gripping jaw descending and releasing + the gripping jaw rising and moving backward to reset. The control program is very simple. In other embodiments of the utility model, stations A and B can also be combined into one, and one worker can complete the placement of the auxiliary support 200 and the main support 100.

[0041] After using the above-mentioned wiper assembly auxiliary equipment, workers only need to simply place the auxiliary bracket 200 / main bracket 100 on the limiting tooling 7, which reduces the workload and fatigue. The assembly process of the bracket assembly is transformed from fully manual to semi-automatic, and the production efficiency and yield rate are improved.
