[0044] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0045] like Figures 1 to 8 The wiper motor plug assembly and oiling device of the utility model includes a positioning unit A, a plug loading mechanism B, a plug extraction component C, a plug assembly drive unit D, an oiling unit E, a workbench F, and a metering pump G. The following describes each part and the relationship between them in detail:

[0046] The positioning unit A is installed on the workbench F. The positioning unit A positions the transmission housing 2. That is, before assembling the plug 4 and applying lubricating grease, the transmission housing 2 needs to be fixed to prevent the transmission housing 2 from shaking.

[0047] In this embodiment, the positioning unit A includes a base plate 11, a support seat 12, and a positioning pin 13. The support seat 12 is fixed to the base plate 11. The support seat 12 is provided with a positioning hole 14 for cooperating with the output shaft 3 mounting hole and the wiper mounting hole on the transmission box 2. There are at least two positioning holes 14, and the positioning pin 13 cooperates with the positioning holes 14.

[0048] The base plate 11 is fixed to the workbench F, and the base plate 11 and the workbench F are preferably fixed by screws. A plurality of L-shaped pressing blocks 15 are provided on the base plate 11, and the pressing blocks 15 are fixed to the base plate 11, for example, the pressing blocks 15 and the base plate 11 are fixed by welding. The pressing blocks 15 are provided with strip holes, and a plurality of pressing blocks 15 form an assembly area. After the support seat 12 is inserted into the gap between the pressing blocks 15 and the base plate 11, screws are used to pass through the strip holes on the pressing blocks 15 and are threadedly connected with the screw holes provided on the base plate 11, so that the support seat 12 is pressed tightly against the base plate 11.

[0049] In this embodiment, the support seat 12 is connected by a transverse mounting plate and a longitudinal mounting plate. The transverse mounting plate is mainly fixed to the base plate 11 and supports the longitudinal mounting plate. The positioning holes 14 are arranged on the longitudinal mounting plate. In this embodiment, the number of positioning holes 14 is preferably 3, namely the first positioning hole 14, the second positioning hole 14, and the third positioning hole 14. The second positioning hole 14 is located between the first positioning hole 14 and the third positioning hole 14. The three positioning holes 14 are arranged on the same straight line along the transverse direction of the longitudinal mounting plate, and the axis line of the second positioning hole 14 is the axial symmetry line of the first positioning hole 14 and the third positioning hole 14.

[0050] Since there are two wipers on the car, each wiper is connected to a wiper motor, and the transmission housings 2 on the two wiper motors are mirror-symmetrical. After the locating pins 13 are installed on the first locating hole 14 and the second locating hole 14, the transmission housing 2 on the first type of wiper motor (for example, the wiper on the left side of the car driver) can be installed through the two locating pins 13, and after the locating pins 13 are installed on the third locating hole 14 and the second locating hole 14, the transmission housing 2 on the second type of wiper motor (for example, the wiper on the right side of the car driver) can be installed through the two locating pins 13. Therefore, the same set of devices can be used for the installation of plugs and oiling of mirror-symmetrical transmission housings 2.

[0051] In this embodiment, the plug loading mechanism B is located on the other side of the positioning unit A. The plug loading mechanism B includes a seat body 20 and a slider 22. The seat body 20 is provided with a sliding fitting portion 21. The slider 22 is slidably matched with the sliding fitting portion 21 on the seat body 20. The slider 22 is provided with a receiving portion 23 for receiving the plug 4. According to the above structure, the plug 4 can be manually placed in the receiving portion 23. Based on this, the position of the receiving portion 23 corresponds to the material taking station of the plug extraction component C and can be kept stationary. As for the loading method of the plug 4, the preferred method is to allow the plug 4 to enter the receiving portion 23 by automatic loading.

[0052] In order to achieve the above-mentioned purpose of automatic feeding, the plug feeding mechanism B in this embodiment also includes an automatic feeder 24 and a first linear drive 26. The automatic feeder 24 preferably adopts a vibration feeder. The base body 20 is provided with a feeding trough 25. The output end of the automatic feeder 24 cooperates with the feeding trough 25. The sliding fitting part 21 is a groove. After the slider 22 is fitted in the groove, the feeding trough 25 is matched with the accommodating part 23; the first linear drive 26 is connected to the slider 22. The first linear drive 26 preferably adopts a cylinder. The first linear drive 26 drives the slider 22 to switch between the plug feeding station and the plug picking station.

[0053] When the accommodating portion 23 cooperates with the feeding trough 25, the accommodating portion 23 on the slider 22 is in the feeding position, and the plug 4 output from the automatic loader 24 enters the feeding trough 25. With the continuous push of the plug 4, the plug 4 located in the feeding trough 25 is pushed into the accommodating portion 23, and the first linear drive 26 drives the slider 22 to move linearly along the sliding fitting portion 21, so that the accommodating portion 23 on the slider 22 moves to the material picking position cooperated with the plug extraction component C. After the plug extraction component C takes away the plug 4, the first linear drive 26 drives the slider 22 to move linearly along the sliding fitting portion 21, so that the accommodating portion 23 on the slider 22 returns to the feeding position, so that the slider 22 switches between the feeding position and the plug picking position.

[0054] The plug extraction component C extracts the plug 4 in the plug feeding mechanism B. The plug extraction component C includes a connecting pipe 30, a suction cup 31, and a negative pressure generator (not shown in the figure). The connecting pipe 30 is connected to the plug assembly drive unit D, one end of the connecting pipe 30 is connected to the suction cup 31, and the other end of the connecting pipe 30 is connected to the negative pressure generator (not shown in the figure). The negative pressure generator can use an air pump.

[0055] The plug assembly drive unit D is connected to the plug extraction component C, and the plug assembly drive unit D drives the plug extraction component C to switch between the plug material taking station and the plug assembly station. The plug assembly drive unit D includes a bracket 40, a connecting plate 41, a lateral drive 42, and a lifting drive 43. The lateral drive 42 is fixed on the bracket 40, the lifting drive 43 is connected to the output end of the lateral drive 42, the connecting plate 41 is connected to the output end of the lifting drive 43, and the plug extraction component C is connected to the connecting plate 41.

[0056] The oiling unit E applies grease to the plug 4 assembled with the transmission housing 2, and the oiling unit E is located on one side of the positioning unit A. The oiling unit E includes a second linear drive 50, a metering valve 51, and an oiling tube 52, wherein the metering valve 51 is connected to the output end of the second linear drive 50, and one end of the oiling tube 52 is connected to the metering valve 51.

[0057] The metering pump G is arranged on the workbench F, and is connected to the metering valve 51 in the oiling unit E to control the given amount of lubricating grease.

[0058] The working process of the utility model is as follows:

[0059] The transmission housing 2 is matched with the positioning pin 13 so that the transmission housing 2 is positioned on the positioning unit A and remains stationary. The automatic loader 24 inputs the plug 4 into the feeding trough 25 by the action of vibration. With the continuous push of the plug 4, the plug 4 located in the feeding trough 25 is pushed into the accommodating portion 23. The first linear driver 26 drives the slider 22 to move linearly along the sliding fitting portion 21, so that the accommodating portion 23 on the slider 22 moves to the material picking station matched with the plug extraction component C. After the transverse drive 42 works to move the lifting drive 43 and the plug extraction component C to the material picking station, the lifting drive 43 works to lower the plug extraction component C, and the plug extraction component C presses on the plug 4. The plug extraction component C generates a negative pressure force to absorb the plug 4. After the lifting drive 43 drives the plug extraction component C to rise, the plug 4 is taken away by the plug extraction component C, and the first linear driver 26 drives the slider 22 to move linearly along the sliding fitting portion 21, so that the accommodating portion 23 on the slider 22 returns to the feeding station. , the transverse drive 42 drives the lifting drive 43 to move to the plug assembly station. At this time, the plug extraction component C corresponds to the bearing chamber 6 on the transmission case 2 and the assembly hole 5 of the worm gear. The lifting drive 43 works to make the plug extraction component C descend. The plug extraction component C carries the plug 4 through the bearing chamber 6 to feed to the assembly hole 5 of the worm gear, and presses the plug 4 into the assembly hole 5 of the worm gear. The plug extraction component C releases the negative pressure on the plug 4 to keep the plug 4 in the assembly hole 5 of the worm gear, and then the lifting drive 43 drives the plug extraction component C to rise. The second linear drive 50 in the oiling unit E works to drive the oiling pipe 52 to move to the plug 4, the metering valve 51 opens, and the lubricating grease is output to the plug 4 through the oiling pipe 52. After the grease coating is completed, the oiling unit E is reset, and the operator takes away the transmission case 2 that has completed the plug assembly and oiling, installs the next transmission case 2 on the positioning unit A, and repeats the above process.

[0060] It can be seen from the above working process that in the process of assembling the plug 4, since the bearing chamber 6 and the assembly hole 5 of the worm are in the same straight line, the bearing chamber 6 is used to give way to the plug extraction component C, thereby smoothly sending the plug 4 into the assembly hole 5 of the worm. This method realizes automated operation without changing the original structure of the transmission box 2.

[0061] Finally, it should be noted that the above-described implementation mode is only a preferred embodiment of the utility model to illustrate the technical solution of the utility model, and does not limit it, let alone limit the protection scope of the utility model; although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the protection scope of the claims.
