Description

Technical Field

[0002] When the windshield of a car is installed on the sheet metal of the frame, a lower clip is set between the windshield and the sheet metal, and the lower clip is used to achieve shock absorption, noise reduction and waterproofing. Therefore, a rationally structured lower clip is the key to ensuring the safe and stable installation of the windshield. The lower clip is formed by the internal aluminum strip glue-plated to form a straight strip, and then the lower clip needs to be curved into an arc so that the lower clip needs to fit the glass. The lower clip is completely bonded to the glass by double-sided tape, which requires a high bonding strength of the double-sided tape, and the double-sided tape needs to be pasted along the arc track of the lower clip. At present, the staff puts the lower clip on the positioning block and sticks it well (the arc track of the positioning block is consistent with the arc track of the lower clip), and one staff member pastes the tape along the arc track of the lower clip, and the other staff member needs to press the lower clip to prevent the lower clip from moving along the positioning block during the process of sticking the tape, and then cut the pasted tape after sticking.

The workbench 1 is provided with a transfer guide mechanism 9, and the transfer guide assembly can move the film and the pressure roller along the arc trajectory of the positioning block. The pressure roller slightly presses the tape of the film so that the tape adheres to the lower card strip along the trajectory of the lower card strip. The longitudinal moving part 7 first causes the side abutment assembly 8 to abut the two notches 3, thereby correcting and abutting the lower card strip. The longitudinal moving part 7 then moves the film 4 and the pressure roller 5 along the arc trajectory of the positioning block 2 through the transfer guide mechanism 9, and the longitudinal moving part 7 drives the cutting assembly 11 to cut the tape. The lower card strip is obliquely attached to the positioning block, and the lower card strip is consistent with the arc trajectory of the positioning block, the servo electric cylinder is started, the servo electric cylinder drives the longitudinal moving part to move backward, and the longitudinal moving part first makes the side abutment assembly side against the two notches, and the side abutment assembly pushes the lower card strip on the positioning block to correct and maintain (the two sides of the lower card strip are flush with the side walls of the notch), and the longitudinal moving part then moves the film and pressure roller to the left along the arc trajectory of the positioning block through the transfer guide mechanism, the tape of the film is continuously output, and the pressure roller slightly presses the tape of the film, so that the tape is firmly adhered to the lower card strip along the arc trajectory of the lower card strip, and the pasted tape is unified and standard. After the pressure roller and the film move to the left to the bottom and the tape is pasted, the longitudinal moving part drives the cutting assembly to cut off the tape pressed by the pressure roller, and then the longitudinal moving part moves forward and resets, and the longitudinal moving part first resets the cutting assembly, and the longitudinal moving part moves the film and pressure roller to the right through the transfer guide assembly to reset, and slightly presses the pasted tape for the second time, and the longitudinal moving part drives the side abutment assembly to reset to loosen the lower card strip.

[0018] See also Figure 8 , Fig.12The longitudinal moving member 7 includes a long strip 7.1 longitudinally arranged on the left side and connected to an inclined plate 7.2 on the right side.

The slider 7.3 is slidably matched on the slide rail for forward and backward movement. A partial tooth 7.4 is arranged at the upper end of the long strip 7.1. A shift block 7.5 located on the right side of the slider 7.3 is arranged at the bottom of the inclined plate 7.2. The piston rod of the servo electric cylinder is connected to the long strip. The inclined surface of the inclined plate drives the block on the left side of the side abutment assembly to move, so that the block abuts against the notch. The straight surface of the inclined plate keeps the block abutting. The long strip locks the locking gear. The partial teeth drive the locking gear of the transfer guide mechanism to rotate, thereby driving the film and the pressure roller to move along the arc track of the positioning block. The pressure roller slightly presses the tape of the film, so that the tape adheres to the lower card strip along the track of the lower card strip. The shift block turns the shifting member of the cutting assembly, so that the cutting assembly cuts the glued tape.

[0019] The side abutment assembly 8 includes a abutment block 8.1 which is symmetrically arranged on the left and right. The abutment block 8.1 on the left is pushed by the inclined plate 7.2. A movable groove 8.3 is provided on the workbench 1. A rack 8.2 which is slidably fitted in the movable groove 8.3 is connected to the bottom of the abutment block 8.1. A first gear 8.4 which rotates in the movable groove 8.3 is meshed with the rack 8.2. The two first gears 8.4 are meshed with each other and are symmetrically arranged on the left and right. A torsion spring is connected between the first gear 8.4 and the movable groove 8.3. The longitudinal moving part moves backward, and the inclined surface of the inclined plate drives the left side block to move along the sliding direction of the left rack. The left rack drives the right rack through the two first gears to move with the block along the sliding direction of the right rack. The block pushes the lower card strip to return to the right position, and the two blocks simultaneously abut against the notches on the left and right sides. The straight surface of the inclined plate keeps the blocks against the lower card strip and the notch.

Part of the teeth of the longitudinal moving part drives the locking gear to rotate, and the locking gear drives the third gear and the screw to rotate through the second gear. The screw drives the screw block to move horizontally with the guide assembly, and the guide assembly drives the film and the pressure roller to move along the arc trajectory of the positioning block. The pressure roller slightly presses the tape of the film so that the tape sticks to the lower clamping strip along the trajectory of the lower clamping strip. The long strip of the longitudinal moving part can lock the locking gear so that the side resistance assembly can correct the lower clamping strip and the cutting assembly can cut the tape. The longitudinal moving part moves forward and resets. Part of the teeth of the longitudinal moving part drives the screw block to move the guide assembly, the pressure roller, and the film to the right and reset.

[0024] The cutting assembly 11 includes a toggle member 11.1 which rotates transversely on the workbench 1 and is toggle-turned by the toggle block 7.5. The toggle member 11.1 is connected to a rotating shaft 11.2 which rotates on the notch 3 through a universal joint. A groove is provided on the workbench 1, and a cutter 11.4 is slidably provided at the groove so as to move up and down. A cam 11.3 which acts on the bottom of the cutter 11.4 is keyed on the rotating shaft 11.2. When the longitudinal moving member moves backward, the toggle block of the longitudinal moving member toggles the toggle member, and the toggle member drives the rotating shaft and the cam to rotate through the universal joint, and the cam drives the cutter to rise to cut off the adhesive tape. Then the longitudinal moving member moves forward to reset, and the toggle block is separated from the toggle member. The toggle member, the cam, and the cutter are reset under the action of gravity.
