Description

Technical Field

[0001] The utility model belongs to the technical field of windshield wiper production, in particular to a rubber block transfer device. Background Art

[0002] A windshield wiper is a sheet-type structure installed in front of the windshield. It consists of an electric motor, a reducer, a four-bar linkage, a wiper arm spindle, a rubber strip, a wiper blade assembly, etc. Its main function is to sweep away rain, snow and dust on the windshield that obstructs vision. The rubber strip is used to be installed on the linkage mechanism and is driven by the motor to scrape away rain, snow and dust on the windshield. During the production of the rubber strip, it is necessary to put a rectangular rubber block into the lower hot pressing mold, and then control the upper hot pressing mold to press down so that the rubber block is hot-pressed between the upper hot pressing mold and the lower hot pressing mold to form multiple rubber strips. Because the current production method mainly relies on manual placement of the rubber block into the lower hot pressing mold to complete the alignment, during the production process, the hand will frequently be extended under the upper hot pressing mold. If the hand is not extended in time during the downward pressing process of the upper hot pressing mold, safety problems will arise, so it is necessary to make improvements. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] The present application embodiment provides a rubber block transfer device, such as Figure 1-Figure 3 As shown, it includes a suction cup 1, a pressing mechanism 2, a first cylinder 5, etc.

[0022] Specifically, the top of the suction cup 1 is connected to the telescopic end of the pressing mechanism 2, the pressing mechanism 2 is fixed to one end of a connecting rod 3, the bottom of the other end of the connecting rod 3 is vertically connected to a rotating shaft 4, the rotating shaft 4 is rotatably connected to a support seat 401, and the top of the rotating shaft 4 has a toothed structure 402; the telescopic end of the first cylinder 5 is connected to one end of a rack 501, and the toothed structure 402 is meshed with the rack 501.

[0023] In actual use, the device can be installed on one side of the hot pressing equipment, and a rubber block placement rack can be set outside the hot pressing equipment. When the telescopic end of the first cylinder 5 is pushed out, the suction cup 1 is outside the hot pressing equipment and directly above the rubber block placement rack. At this time, the telescopic end of the pressing mechanism 2 is controlled to be pushed out, so that the suction cup 1 can adsorb the rubber block on the placement rack, and then the telescopic end of the pressing mechanism 2 is controlled to be retracted, and the telescopic end of the first cylinder 5 is controlled to be retracted, and the connecting rod 3 and the suction cup 1 are driven to rotate through the rotating shaft 4 to transfer the rubber block to directly above the lower hot pressing mold of the hot pressing equipment, and then the telescopic end of the pressing mechanism 2 is controlled to be pushed out, so that the rubber block can be placed in the lower hot pressing mold to complete the alignment.

[0024] For details, see Figure 1 The rack 501 is slidably connected in a first sliding sleeve 502 , and the first sliding sleeve 502 is connected to the support seat 401 through a vertical plate 503 to achieve stability of the rack 501 during movement.

[0025] For details, see Figure 2 , Figure 3 A pair of guide holes 301 are formed at one end of the connecting rod 3 away from the rotating shaft 4. The pressing mechanism 2 is disposed between the pair of guide holes 301. Guide posts 302 are inserted into the guide holes 301. The bottom of the guide posts 302 is connected to the top of the suction cup 1. When the telescopic end of the pressing mechanism 2 is pushed out, the guide posts 302 can only move axially along the guide holes 301, thereby preventing the suction cup 1 from deflecting during the downward movement. More specifically, the telescopic end of the pressing mechanism 2 is connected to the top of the suction cup 1 through a connecting plate 3021. The connecting plate 3021 can be connected to the suction cup 1 through screws. The bottom of the guide posts 302 is connected to the connecting plate 3021. In this way, the suction cup 1 can be easily disassembled and replaced.

[0026] Preferably, see Figure 3The connecting rod 3 includes a front section 303 and a rear section 304. The front section 303 is connected to the telescopic end of a second cylinder 6, and the rear section 304 is connected to the fixed end of the second cylinder 6. The front section 303 is connected to the pressing mechanism 2, and the rear section 304 is connected to the rotating shaft 4. The overall length of the connecting rod 3 can be controlled by controlling the telescopic end of the second cylinder 6 to be pushed out or retracted. When the upper hot pressing mold and the lower hot pressing mold of the hot pressing equipment are slidably connected by the sliding column, the telescopic end of the second cylinder 6 can be controlled to retract when the suction cup 1 rotates to prevent the suction cup 1 from being blocked by the sliding column. When the suction cup 1 rotates to face the hot pressing equipment, the telescopic end of the second cylinder 6 is controlled to be pushed out, so that the suction cup 1 can reach directly above the lower hot pressing mold. When the rubber block adsorbed by the suction cup 1 is too large or too small and does not match the lower hot pressing mold, the rubber block can be sucked up by the suction cup 1 and then driven to rotate above the rubber block placement rack. At this time, the telescopic end of the second cylinder 6 is controlled to be pushed out, and the suction cup 1 is controlled to cancel the adsorption, so that the rubber block that does not match the size falls to another place on the rubber block placement rack, which is different from other rubber blocks, so that it is easy to distinguish from other unprocessed rubber blocks.

[0027] For details, see Figure 1 , Figure 3 The second cylinder 6 is disposed in a second sleeve 7, and the second sleeve 7 is sleeved outside the front section 303 and the rear section 304, and the front section 303 is slidably connected to the sleeve, and the rear section 304 is fixedly connected to the sleeve. The sleeve can generate a supporting force for the front section 303, so as to avoid the telescopic end of the second cylinder 6 bearing the gravity of the front section 303, the suction cup 1 and the rubber block alone, and to avoid the telescopic end of the second cylinder 6 being subjected to a downward force for a long time and deforming. For more details, refer to Figure 1 The bottom of the second sliding sleeve 7 is connected to one end of an inclined rod 8, and the other end of the inclined rod 8 is connected to the rotating shaft 4. The inclined rod 8 and the sliding sleeve, the rear section 304, and the rotating shaft 4 can form a triangular structure, so that the rotating shaft 4 supports the sliding sleeve through the inclined rod 8, which can further improve the stability of the device.

[0028] The above are only some of the embodiments listed in this application and are not intended to limit this application.
