Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a gantry type automatic film taking machine. Background Art

[0002] The condenser and evaporator are important components of the air conditioner, and the fin group and U-shaped copper tube are the main parts of the condenser and evaporator. The fin group and the U-shaped copper tube are usually assembled manually. The fin group is first positioned by a positioning mold, and then the workers insert the U-shaped copper tube into the fin group. However, due to the large size of the assembled product, the workers cannot independently remove the assembled product from the positioning mold, and the fins are relatively fragile and easily damaged. Therefore, a fin extractor is designed to extract the assembled fin group from the positioning mold. The fin extractor currently used has a complex structure and occupies a large space, which requires enterprises to invest more costs to increase the factory area.

[0003] In view of the above problems, the utility model document proposes a gantry type automatic film taking machine. Utility Model Content

[0026] Example:

[0027] Reference Figure 1-Figure 4 As shown, a gantry 1 type automatic film pick-up machine comprises a gantry 1, a crane 2 is arranged on the gantry 1, a lifting mechanism is arranged on the crane 2, and a clamping mechanism is arranged on the lifting mechanism;

[0028] The clamping mechanism includes a supporting frame 3, which is horizontally arranged. A clamping slide rail 4 is arranged on the top surface of the side wall along its length direction. Two groups of clamping units are arranged on the clamping slide rail 4. The clamping unit includes a rectangular clamping frame 7 and a clamping power assembly that drives the clamping frame 7 to move. The clamping frame 7 is arranged on the outer side of the supporting frame 3. The clamping power assembly includes a clamping motor 5 and a screw rod 6. The output shaft of the clamping motor 5 is connected to the screw rod 6 through power transmission. A first sliding block 8 that cooperates with the screw rod 6 is provided on the clamping frame 7. The clamping motor 5 and the screw rod 6 are arranged on the supporting frame 3, and the screw rod 6 is arranged parallel to the clamping slide rail 4.

[0029] The size of the rectangular clamping frame 7 is larger than the fin group. The clamping motor 5 drives the screw rod 6 to rotate. The rotation of the screw rod 6 causes the first slider 8 to move along the screw rod 6. The movement of the first slider 8 drives the clamping frame 7 to move along the supporting frame 3. The clamping frames 7 of the two clamping units can move toward each other to cover the clamping frame 7 on the outside of the fin group, and can move away from the outside of the fin group.

[0030] The lifting mechanism drives the clamping mechanism to move up and down, and the two clamping frames 7 clamp the fin group inside the clamping frame 7. The lifting mechanism moves upward, driving the clamping frame 7 to move upward. The bottom side wall of the clamping frame 7 supports the bottom of the fin group, driving the fin group to move upward together, and the fin group can be lifted up and separated from the mold. The two clamping frames 7 ensure that the fin group is evenly stressed, which can ensure the stability of the movement of the fin group, improve the safety of the movement of the fin group, and effectively prevent the fin group from being damaged.

[0031] A positioning plate 9 is provided in the middle of the support frame 3, one end of the screw rod 6 is rotatably set on the positioning plate 9, and the other end is rotatably set on the side wall in the width direction of the support frame 3. Bearings are clamped at positions corresponding to the screw rod 6 on the positioning plate 9 and the support frame 3, and the end of the screw rod 6 is arranged in the bearing.

[0032] The positioning plate 9 facilitates the installation of the screw rod 6 and also reduces the use length of the screw rod 6. Since there are two groups of clamping units moving toward or away from each other on the support frame 3, the moving range of each group of clamping units on the support frame 3 is basically half of the length of the support frame 3. The positioning plate 9 is arranged in the support frame 3, so that the length of the screw rod 6 does not need to reach the length of the support frame 3. The two ends of the screw rod 6 can be respectively installed on the positioning plate 9 and the side wall of the end of the support frame 3. The length of the screw rod 6 is shortened and its bearing strength is correspondingly increased, thereby ensuring the stability of the rotation of the screw rod 6.

[0033] The clamping motor 5 is arranged on the side wall of the support frame 3 in the width direction. The output shaft of the clamping motor 5 is provided with a driving wheel, and the end of the screw rod 6 is provided with a driven wheel. The driving wheel and the driven wheel are connected by a belt.

[0034] The clamping motor 5 drives the screw rod 6 to rotate through a belt drive to reduce the noise of the equipment operation. In addition, a leather bag drive is adopted so that the clamping motor 5 and the screw rod 6 do not need to be in the same straight line. On the one hand, it reduces the space occupation, and on the other hand, it avoids the clamping motor 5 being placed outside and affecting the safety of use.

[0035] The supporting frame 3 is located inside the clamping frame 7 , and the clamping frame 7 is arranged perpendicular to the supporting frame 3 . A second sliding block 10 matching with the clamping slide rail 4 is arranged on the inner side surface of the upper side wall of the clamping frame 7 .

[0036] The clamping frame 7 can accurately clamp the fin group inside, while ensuring the stability of the clamping of the fin group. The second slider 10 cooperates with the clamping rail 4 so that the clamping frame 7 can slide on the supporting frame 3.

[0037] The lifting mechanism includes a lifting plate 11, a lifting power assembly and a lifting rail 13. There are two lifting rails 13, which are arranged parallel to each other on the trolley 2 and perpendicular to the support frame 3. The lifting plate 11 is slidably arranged on the lifting rail 13. The lifting power assembly controls the movement of the lifting plate 11. The support frame 3 is fixedly arranged on the lifting plate 11.

[0038] The operation of the lifting power assembly drives the lifting plate 11 and the lifting rail 13 to slide, and the support frame 3 is set on the lifting plate 11, which in turn drives the support frame 3 to move up and down, so that the clamping unit on the support frame 3 moves up and down, and the two clamping units clamp the fin group, thereby driving the fin group to move and separate it from the mold.

[0039] It also includes a support plate 14, one end of which is fixedly arranged on the traveling crane 2, and the support plate 14 is arranged parallel to the lifting track 13. The lifting power assembly includes a lifting motor 12 and a transmission rack 15. The lifting motor 12 is arranged on the lifting plate 11, and the power transmission on the output shaft of the lifting motor 12 is connected with a transmission shaft, and a transmission gear 16 is arranged on the transmission shaft. The transmission rack 15 is fixedly arranged on the support plate 14, and the transmission gear 16 is meshed with the transmission rack 15.

[0040] A transmission rack 15 is arranged on the traveling crane 2 through the support plate 14, and the lifting motor 12 is arranged on the lifting plate 11. The lifting motor 12 drives the transmission gear 16 to rotate, so that the transmission moves on the transmission rack 15, so that the lifting plate 11 moves along the transmission rack 15, and the transmission rack 15 is arranged parallel to the lifting guide rail, so that the lifting plate 11 moves along the lifting guide rail, and at the same time, the lifting guide rail is used to improve the stability of the movement of the lifting plate 11.

[0041] It also includes a structure reinforcement plate 17 , which is arranged at the bottom end of the lifting slide rail, and the bottom end of the support plate 14 is also fixedly connected to the structure reinforcement plate 17 .

[0042] The structural reinforcement plate 17 improves the stability of the support plate 14 and the lifting rail, avoids the lifting plate 11 from being unstable during movement, avoids damage to the fin group, and even the risk of falling, thereby improving safety in use.

[0043] When in use, after the U-shaped copper tube on the fin group is installed, the fin group needs to be removed from the positioning mold, and the crane 2 is started to move the crane 2 on the gantry 1. When the position of the clamping mechanism corresponds to the position of the fin group, the crane 2 stops, and the clamping motor 5 is started to move the two clamping frames 7 back to back. When the distance between the two clamping frames 7 is greater than the width of the fin group, the clamping motor 5 is turned off, and the lifting motor 12 is started at the same time, so that the lifting motor 12 drives the transmission gear 16 to rotate, and the transmission gear 16 moves along the transmission rack 15, driving the lifting plate 11 along The lifting track 13 slides, and when the horizontal position of the inner side surface of the bottom side wall of the clamping frame 7 is lower than the horizontal position of the bottom surface of the fin group, the lifting motor 12 is turned off, and the clamping motor 5 is started at the same time, so that the two clamping frames 7 move toward each other, so that the two clamping frames 7 are sleeved on the outside of the fin group, and then the clamping motor 5 is turned off, and then the lifting motor 12 is started, so that the supporting frame 3 moves upward, driving the two clamping frames 7 to move upward, the bottom of the clamping frame 7 supports the fin group, and the side wall can protect the fin group. At the same time, the fin group is lifted up and removed from the mold.

[0044] In actual use, both the clamping motor 5 and the lifting motor 12 are forward and reverse servo motors.

[0045] The gantry 1 is used for support, and at the same time, the use of the space below the gantry 1 is not affected. The film loading machine occupies less space, thereby reducing the cost investment of the enterprise.

[0046] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model; in the absence of conflicts, the embodiments of the utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
