[0002] When the front windshield of an automobile is installed on the sheet metal of the vehicle frame, a lower strip is provided between the front windshield and the sheet metal. Shock absorption, noise reduction, and waterproofing are achieved through the lower strip. Therefore, a lower strip with a reasonable structure is the key to ensuring the safe and stable installation of the front windshield. The lower strip is formed into a straight strip by plating glue on an internal aluminum strip, and then the lower strip needs to be bent into an arc shape later so that the lower strip can fit the glass. The lower strip is completely adhered to the glass by double-sided tape, which requires a relatively high bonding strength of the double-sided tape, and the double-sided tape needs to be pasted along the arc track of the lower strip. Currently, the staff places the lower strip against the positioning block (the arc track of the positioning block is the same as that of the lower strip). One staff member pastes the tape along the arc track of the lower strip, and another staff member needs to hold down the lower strip to prevent the lower strip from moving along the positioning block during the process of pasting the tape. After pasting, the taped strip is cut off. It is very difficult to paste the tape along the arc track of the lower strip, and it is difficult to ensure the pasting quality, and the operation is time-consuming and laborious, resulting in low production efficiency.

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.

[0030] See also Figure 8 , Figure 12 The 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. A slider 7.3 is longitudinally arranged at the bottom of the long strip 7.1. A slide rail is longitudinally arranged on the left side of the workbench 1. 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.

[0031] The side abutting assembly 8 includes abutting blocks 8.1 arranged symmetrically left and right. The left abutting block 8.1 is pushed by the inclined plate 7.2. An activity groove 8.3 is formed on the workbench 1. A rack 8.2 that is slidably fitted in the activity groove 8.3 is connected to the bottom of the abutting block 8.1. A first gear 8.4 that rotates in the activity groove 8.3 is engaged with the rack 8.2. The two first gears 8.4 are engaged with each other and arranged symmetrically left and right. A torsion spring is connected between the first gear 8.4 and the activity groove 8.3. When the longitudinal moving member moves backward, the inclined surface of the inclined plate drives the left abutting block to move along the sliding direction of the left rack. The left rack drives the right rack through the two first gears, and the right rack drives the abutting block to move along the sliding direction of the right rack. The abutting block pushes the lower clamping strip to be corrected. The two abutting blocks simultaneously abut against the notches on the left and right sides. The straight surface of the inclined plate makes the abutting block keep abutting against the lower clamping strip and the notch. After the tape is adhered and cut off, the longitudinal moving member moves forward. The inclined plate disengages from the left abutting block. The abutting blocks, racks, and first gears on the left and right sides are reset under the action of the torsion spring.

A horizontally arranged screw rod 9.4 is key-connected to the center of the third gear 9.3. Limit blocks for the rotation of the screw rod 9.4 are symmetrically arranged on the left and right sides at the upper end of the workbench 1. A guide rod 9.5 parallel to the screw rod 9.4 is connected between the two limit blocks. A screw block 9.6 that is slidably fitted on the guide rod 9.5 is screwed on the screw rod 9.4. A guiding assembly 10 is rotatably arranged on the screw block 9.6. The part of the teeth of the longitudinal moving member drives the locking gear to rotate. The locking gear drives the third gear and the screw rod to rotate through the second gear. The screw rod drives the screw block to drive the guiding assembly to move horizontally. The guiding assembly drives 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 is adhered to the lower clamping strip along the track of the lower clamping strip. The long strip of the longitudinal moving member can lock the locking gear, so that the side abutting assembly corrects the lower clamping strip and the cutting assembly cuts off the tape. The longitudinal moving member moves forward and resets. The part of the teeth of the longitudinal moving member drives the screw block to drive the guiding assembly, the pressure roller, and the film to move rightward and reset. The pressure roller slightly presses the adhered tape for the second time, so that the tape is firmly adhered.

[0033] The guiding assembly 10 includes an elastic telescopic rod 10.1 that rotates on the screw block 9.6. A vertical block 10.2 is arranged at the upper end of the elastic telescopic rod 10.1. The film 4 and the pressure roller 5 are both connected to the vertical block 10.2. A first roller 10.3 that rolls on the front surface of the positioning block 2 is rotatably arranged at the end of the elastic telescopic rod 10.1. When the screw block drives the guiding assembly to move horizontally, the elastic telescopic rod expands and contracts and rotates along with the front surface of the positioning block through the first roller, so that the pressure roller and the film on the vertical block move along the arc track of the positioning block (the arc track of the positioning block is also the arc track of the lower clamping strip).

[0034] At the upright block 10.2, a reel 10.5 and a roller 10.6 are locked by locking bolts. The film 4 and the pressure roller 5 rotate on the reel 10.5 and the roller 10.6 respectively. At the rear end of the reel 10.5, a second roller is provided that rolls on the top of the positioning block 2. The reel and the roller can be adjusted by the locking bolts, thereby adjusting the film and the pressure roller. The second roller is provided to bear the weight of the film.

[0035] At the lower end of the elastic telescopic rod 10.1, a support rod 10.4 is vertically provided. At the end of the support rod 10.4, a ball is provided that rolls on the workbench 1. The upright block, the pressure roller, and the film above are carried by the support rod and the ball.

[0036] The cutting assembly 11 includes a toggling member 11.1 that rotates horizontally on the workbench 1 and is toggled by the toggle block 7.5. The toggling member 11.1 is connected by a universal joint to a rotating shaft 11.2 that rotates in the notch 3. A groove is provided on the workbench 1, and a cutter 11.4 is slidably fitted up and down at the groove. A cam 11.3 that 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 toggling member. The toggling member drives the rotating shaft and the cam to rotate through the universal joint. The cam drives the cutter to rise to cut the taped tape. Then the longitudinal moving member moves forward and resets. The toggle block disengages from the toggling member, and the toggling member, the cam, and the cutter reset under the action of gravity.

[0037] Refer to Figure 8 、 Figure 13 The toggling member 11.1 is composed of a shaft portion 11.1.1 on the right side connecting to a rod portion 11.1.2 on the left side. A bent strip 11.1.3 that is toggled by the toggle block 7.5 is connected to the side wall of the rod portion 11.1.2. The rearward moving toggle block contacts and pushes the bent strip, thereby driving the shaft portion to rotate. The rod portion is provided to avoid the rearward moving toggle block.

[0038] The specific working process of the present invention is as follows: The staff obliquely attaches the lower card strip to the positioning block, as Figure 5 shown, and attaches a little tape of the film to the right side of the lower card strip. The servo cylinder is started. The servo cylinder drives the longitudinal moving member to move backward. The long strip of the longitudinal moving member can lock the locking gear. The inclined surface of the inclined plate of the longitudinal moving member drives the left abutting block to move along the sliding direction of the left rack. The left rack drives the right rack through two first gears to drive the abutting block to move along the sliding direction of the right rack. The abutting block pushes the lower card strip to be corrected. The two abutting blocks simultaneously abut against the notches on the left and right sides. The straight surface of the inclined plate keeps the abutting block abutted against the lower card strip and the notch, as Figure 6As shown, part of the teeth of the longitudinal moving member drives the locking gear to rotate, and the locking gear drives the third gear and the screw to rotate through the second gear, and the screw drives the screw block to move the guide assembly to the left, and the elastic telescopic rod extends and rotates along the front end surface of the positioning block through the first roller, so that the pressure roller and the film on the vertical block move along the arc track of the positioning block, and 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, and part of the teeth are separated from the locking gear and the long strip locks the locking gear, and the screw block moves to the left with the guide assembly, the pressure roller, and the film to the bottom to stick the tape, as shown in FIG. Figure 7 As shown, the shifting block of the longitudinal moving member then turns the shifting member, and the shifting member drives the rotating shaft and the cam to rotate through the universal joint. The cam drives the cutter to rise to cut off the tape pressed by the pressure roller, and then the longitudinal moving member moves forward and resets, and the shifting block of the longitudinal moving member is separated from the shifting member, and the shifting member, the cam and the cutter are reset under the action of gravity. Part of the teeth of the longitudinal moving member drives the screw block with the guide assembly, the pressure roller and the film to move right and reset, and the pressure roller slightly presses the stuck tape for the second time, and the inclined plate of the longitudinal moving member is separated from the retaining block on the left, and the retaining blocks, racks and the first gear on the left and right sides are reset under the action of the torsion spring to loosen the lower clamping strip, and the staff removes the lower clamping strip that has been stuck with the tape.
