[0033] The first clamping unit 2 includes a support seat 21, a movable seat 22, a first rolling assembly 23, and a first driving assembly 24; the support seat 21 is slidably connected to the frame 1; the first rolling assembly 23 is slidably connected to the movable seat 22; the movable seat 22 is slidably connected to the support seat 21; a pulley 25 is provided at the bottom of the movable seat 22; a groove 11 is provided on the frame 1; the pulley 25 cooperates with the groove 11 to enable the first rolling assembly 23 to continuously adhere to the side rubber strip 8; the first driving assembly 24 is connected to the support seat 21; the first driving assembly 24 is used to drive the first rolling assembly 23 to approach or move away from the side rubber strip 8.

[0034] The wiper cover plate 6 needs to be installed with a top rubber strip 7 and a side rubber strip 8. The assembly device is used for the assembly of the top rubber strip 7 and the side rubber strip 8. The driving unit 4 can select a combination of a gear rack and a motor or a cylinder. The present embodiment preferably adopts a combination of a gear rack and a motor. The motor is connected to the first clamping unit 2, the gear is connected to the power output end of the motor, and the rack is connected to the frame 11. The motor drives the gear to rotate on the rack, thereby driving the first clamping unit 2 to move along the length direction of the rubber strip. The second clamping unit 3 is connected to the first clamping unit 2 through the connecting frame 27, and the second clamping unit 3 is located above the top rubber strip 7. When the driving unit 4 drives the first clamping unit 2 to move, it also drives the second clamping unit 3 to move at the same time. The length direction of the rubber strip is the direction indicated by the projection of the top rubber strip or the side rubber strip on the vertical plane. In more popular terms, it is horizontal movement.

[0035] The specific working process of the assembly device is as follows: the staff places the wiper cover 6 on the fixing unit 5, starts the fixing unit 5, and makes the fixing unit 5 fix the wiper cover 6 on the frame 1; the staff then places the top rubber strip 7 and the side rubber strip 8 on the corresponding positions of the wiper cover 6, starts the first clamping unit 2 and the second clamping unit 3, makes the first clamping unit 2 press on the side rubber strip 8, and the second clamping unit 3 press on the top rubber strip 7; the driving unit 4 drives the first clamping unit 2 and the second clamping unit 3 to move along the length direction of the rubber strip, thereby assembling the top rubber strip 7 and the side rubber strip 8 on the wiper cover 6.

[0036] In this way, the rubber strips on the wiper cover plate 6 are pressed at one time, which improves the efficiency of pressing the rubber strips and reduces the labor intensity of the staff.

[0037] The moving seat 22 is provided with an optical axis; the supporting seat 21 is provided with a linear bearing, and the moving seat 22 is inserted into the linear bearing through the optical axis to realize the sliding connection of the moving seat 22 on the supporting seat 21.

[0038] The first driving assembly 24 drives the first rolling assembly 23 to press against the side rubber strip 8, and the driving unit 4 drives the supporting seat 21 to move on the frame 1, so that the pulley 25 rolls on the inner wall of the groove 11, and the shape of the groove 11 matches the shape of the installation position of the side rubber strip 8, and the distance between the edge of the groove 11 and the installation position of the side rubber strip 8 remains unchanged. The movable seat 22 moves the optical axis in the linear bearing to realize the position adjustment of the movable seat 22, thereby ensuring that the distance between the movable seat 22 and the wiper cover 6 remains unchanged, so that the first rolling assembly 23 can always press the side rubber strip 8.

[0039] Preferably, the first rolling assembly 23 includes a mounting seat 231 and a first pressure wheel 232 ; a limiting plate 233 is provided on the side of the mounting seat 231 away from the wiper cover 6 ; a sliding shaft 234 is provided on the limiting plate 233 ; the mounting seat 231 is slidably connected to the moving seat 22 via the sliding shaft 234 .

[0040] In this embodiment, the first driving assembly 24 drives the mounting seat 231 to approach the side rubber strip 8 until the limiting plate 233 is pressed against the moving seat 22, so that the distance between the first pressing wheel 232 and the side rubber strip 8 is the same each time, thereby ensuring the pressing force of the first pressing wheel 232 on the side rubber strip 8. The first driving assembly 24 is a cylinder.

[0041] Preferably, an adjusting rod 235 is provided on one side of the mounting seat 231 close to the wiper cover 6 ; the first pressure wheel 232 is slidably connected to the adjusting rod 235 ; the adjusting rod 235 is provided with a first spring 236 ; the first spring 236 is used to adjust the height of the first pressure wheel 232 .

[0042] In this embodiment, the height of the entire side rubber strip 8 is not the same, the adjustment rod 235 is vertically mounted on the mounting seat 231, the first pressing wheel 232 is slidably connected to the adjustment rod 235, and a first spring 236 is provided between the first pressing wheel 232 and the mounting seat 231. When the first pressing wheel 232 needs to move to different heights following the side rubber strip 8, the first pressing wheel 232 is slidably connected to the adjustment rod 235, and the first pressing roller slides on the adjustment rod 235 according to the height of the side rubber strip 8, thereby adjusting the height of the first pressing wheel 232. Secondly, by providing the first spring 236 between the first pressing wheel 232 and the mounting seat 231, the force required for adjusting the first pressing wheel 232 is reduced.

[0043] Preferably, the second clamping unit 3 includes a second rolling assembly 31 and a second driving assembly 32; the second driving assembly 32 is connected to the connecting frame 27; the second rolling assembly 31 is connected to the power output end of the second driving assembly 32; the second driving assembly 32 is used to drive the second rolling assembly 31 to move closer to or away from the top rubber strip 7.

[0044] In this embodiment, the second driving assembly 32 is connected to the connecting frame 27. When the top rubber strip 7 needs to be compressed, the second driving assembly 32 drives the second rolling assembly 31 to descend, so that the second rolling assembly 31 compresses the top rubber strip 7. After the top rubber strip 7 is compressed, the second driving assembly 32 drives the second rolling assembly 31 to rise, so that the second rolling assembly 31 is separated from the top rubber strip 7. The second driving assembly 32 is a cylinder.

[0045] Preferably, the second rolling assembly 31 includes a connecting plate 311, a rotating plate 312, a second pressure wheel 313, and a second spring 314; the connecting plate 311 is connected to the power output end of the second driving assembly 32; the rotating plate 312 is rotatably connected to the connecting plate 311; the second pressure wheel 313 is connected to the side of the rotating plate 312 close to the wiper cover 6; the two ends of the second spring 314 are respectively connected to the connecting plate 311 and the rotating plate 312; the second spring 314 is used to drive the rotating plate 312 to swing toward the top rubber strip 7 so that the second pressure wheel 313 presses the top rubber strip 7.

[0046] When the cam 312 is in the unlocking state, the second spring 314 is used to unlock the top of the cam 313 so that the cam 313 can be unlocked when the cam 313 is unlocked.

[0047] Preferably, an elastic sheet 315 is provided at the front end of the second pressing wheel 313 ; the elastic sheets 315 are symmetrically arranged on both sides of the top rubber strip 7 ; the elastic sheets 315 are used to press the side surfaces of the top rubber strip 7 .

[0048] In this embodiment, since the top rubber strip 7 is relatively high in height, the top rubber strip 7 may be tilted when the second pressing wheel 313 is used to press the top rubber strip 7, so that the second pressing wheel 313 cannot press the top rubber strip 7 well. Therefore, when the second pressing wheel 313 presses the top rubber strip 7, the two symmetrically arranged elastic sheets 315 clamp the top rubber strip 7. After the elastic sheets 315 clamp the top rubber strip 7, the second pressing wheel 313 presses the top rubber strip 7 again, so that the top rubber strip 7 remains vertical during the pressing process, thereby improving the assembly quality of the top rubber strip 7.

[0049] Preferably, the fixing unit 5 includes a fixing module 51 and an overlapping boss 52; the upper surface of the overlapping boss 52 matches the shape of the wiper cover 6; the overlapping boss 52 is used to place the wiper cover 6; the fixing modules 51 are respectively located on both sides of the overlapping boss 52; the fixing modules 51 are used to fix the wiper cover 6.

[0050] In this embodiment, a plurality of overlapping bosses 52 are arranged on the frame 1 according to the shape of the wiper cover 6, so that the wiper cover 6 can be stably placed on the overlapping bosses 52. After the placement is completed, the fixing module 51 is started to press the wiper cover 6, so that the wiper cover 6 remains stationary when the rubber strip is assembled, thereby ensuring the assembly quality of the rubber strip.

[0051] Preferably, the fixing module 51 includes a cylinder 511 and a pressing block 512 ; the pressing block 512 is connected to the power output end of the cylinder 511 ; the cylinder 511 is used to drive the pressing block 512 to approach or move away from the surface of the wiper cover 6 .

[0052] In this embodiment, after the wiper cover 6 is placed, the cylinder 511 is started, so that the power output end of the cylinder 511 drives the pressing block 512 to move toward the wiper cover 6 and press the wiper cover 6. After the rubber strip is installed, the cylinder 511 is started, and the power output end of the cylinder 511 drives the pressing block 512 to separate from the wiper cover 6.

[0053] Preferably, the first clamping unit 2 is provided with a third driving assembly 26 ; the connecting frame 27 is rotatably connected to the first clamping unit 2 ; and the power output end of the third driving assembly 26 is rotatably connected to a side of the connecting frame 27 away from the second clamping unit 3 .

[0054] In this embodiment, the third driving assembly 26 is rotatably connected to the first clamping unit 2, and the third driving assembly 26 is a cylinder. The staff drives the power output end of the third driving assembly 26 to contract, so that the connecting frame 27 drives the second clamping unit 3 to move in a direction away from the wiper cover 6, so that the staff can place the wiper cover 6 on the overlapping boss 52. After the wiper cover 6 is placed, the power output end of the third driving assembly 26 is started to extend, so that the second clamping unit 3 moves to the top of the wiper cover 6, and the second clamping unit 3 presses the top rubber strip 7 downward.
