Description

Technical Field

[0001] This utility model relates to the field of fixed structure technology, specifically to a carrier belt deformation fixing structure. Background Technology

[0002] Carrier tape packaging is a strip-shaped product used for packaging electronic components. It is mainly used in the electronic component mounting industry. It has a specific thickness and has holes or positioning holes for indexing and positioning distributed at equal intervals along its length. Existing carrier tapes are usually stored and placed on a reel, and the output of the carrier tape is achieved by rotating the reel.

[0003] A prior art patent with publication number CN212244032U discloses a solution comprising a carrier belt machine body, a top plate, and a support. The carrier belt machine body has a conveyor groove on its surface and a concealed groove inside. A first bevel gear is welded to the left end of a threaded rod, and a second bevel gear is meshed above the first bevel gear. A slider is threaded to the outer side of the threaded rod. A first guide groove is formed inside the upper end of the limiting side plate. A first connecting plate is fixedly connected to the lower surface of the top plate, and ball bearings are provided on the lower surface of the top plate. A second guide groove is formed inside the top plate, and a through hole is formed inside the support. This carrier belt machine, with its limiting and fixing mechanism, can effectively limit carrier belts of different sizes, reduce friction between the carrier belt and the carrier belt machine, and can flatten and arrange the carrier belt, improving the processing effect of the carrier belt machine. It can also effectively adjust the tension of the carrier belt during the conveying process.

[0004] With use, existing devices, including those mentioned above, have gradually revealed shortcomings in this technology, mainly in the following aspects:

[0005] Existing carrier tape loading and unloading mechanisms require the carrier tape to be stretched open before the product is placed in place. Due to the structural limitations of current carrier tape loading and unloading machines, when the carrier tape is stretched open, products that are already installed on one side are easily damaged by the deformation of the carrier tape, which in turn reduces the yield rate.

[0006] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a carrier belt deformation fixing structure to solve the problem that, due to the structural limitations of current carrier belt installation and removal machines, when the carrier belt is stretched open, products already installed on one side are easily damaged by the deformation of the carrier belt, thus reducing the yield rate.

[0008] To achieve the above objectives, the present invention provides the following technical solution.

[0009] The carrier tape deformation and fixing structure includes two carrier tape loading and unloading machines arranged side by side, and a carrier tape passage area is formed between the two carrier tape loading and unloading machines; the carrier tape loading and unloading machine includes a lifting plate that is vertically raised and lowered, a lifting claw is fixed on the lifting plate, and a positioning block that is vertically raised and lowered is connected to one side of the lifting claw. The positioning block is connected to the lifting plate through an elastic structure. Under normal conditions, the upper surface of the positioning block is higher than the upper surface of the lifting claw.

[0010] As an optimized solution, the elastic structure includes a vertically fixed compression spring, and the positioning block is supported on the upper end of the compression spring.

[0011] As an optimized solution, an L-shaped bracket is fixed on the lifting plate, a guide post is vertically slidably mounted on the bracket, a compression spring is fitted onto the guide post, the upper end of the guide post is fixedly connected to the lower surface of the positioning block, and the lower end of the compression spring abuts against the upper surface of the bracket.

[0012] As an optimized solution, two guide posts are arranged side by side, and two compression springs are arranged accordingly.

[0013] As an optimized solution, a telescopic cylinder is fixedly connected to the upper end of the lifting plate, and the telescopic end of the telescopic cylinder passes through the lifting plate and is fixedly connected to the fixed plate.

[0014] As an optimized solution, a positioning plate is fixedly provided on the fixing plate. The positioning plate is located above the carrier belt and close to the upper surface of the side wall of the carrier belt.

[0015] As an optimized solution, guide posts are fixedly connected in parallel on the fixed plate, and guide holes matching the guide posts are opened on the lifting plate.

[0016] As an optimized solution, the lifting claw is L-shaped and located below the carrier belt and close to the lower surface of the carrier belt sidewall.

[0017] As an optimized solution, the positioning plate is provided with a clearance channel to avoid the lifting claw.

[0018] As an optimized solution, the bracket is provided with a guide hole, and the guide post is slidably connected in the guide hole.

[0019] As an optimized solution, the lower end of the guide post is provided with a threaded groove, and a limit screw is threadedly connected in the threaded groove. The shank of the limit screw abuts against the lower surface of the bracket.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] When the carrier belt is opened and products are loaded, the telescopic cylinders of the carrier belt unloading and loading machine on both sides of the carrier belt extend simultaneously. Since the telescopic rod is connected to the fixed plate, the cylinder body of the telescopic cylinder drives the lifting plate to rise. Because there is a positioning block connected to the lifting plate, and the height of the positioning block is normally higher than the lifting claw, the positioning block will first abut against the lower surface of the side wall of the carrier belt. The upper surface of the side wall of the carrier belt is limited by the action of the positioning plate, thus fixing the carrier belt. As the lifting plate continues to rise, the lifting claw will abut against the unloaded carrier belt on one side, opening it up, and then the product is placed in. Because of the positioning block, the positioning block will fix the carrier belt with the product already loaded on the side of the lifting claw, which can prevent the lifting claw from opening the unloaded carrier belt and deforming the carrier belt with the product loaded on the other side as well. Because the positioning block fixes the carrier belt with the product loaded on the side of the lifting claw, it can prevent the product from being damaged due to the deformation of the carrier belt, thereby improving the product yield.

Detailed Implementation

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] like Figures 1 to 3As shown, the carrier belt deformation and fixing structure includes two carrier belt unloading and loading machines 2 arranged in parallel, and the area between the two carrier belt unloading and loading machines 2 forms the carrier belt 1 passage area; the carrier belt unloading and loading machine 2 includes a lifting plate 3 that is vertically raised and lowered, a lifting claw 4 fixed on the lifting plate 3, and a positioning block 5 that is vertically raised and lowered connected to one side of the lifting claw 4. The positioning block 5 is connected to the lifting plate 3 through an elastic structure. Under normal conditions, the upper surface of the positioning block 5 is higher than the upper surface of the lifting claw 4.

[0029] The elastic structure includes a vertically fixed compression spring 6, with a positioning block 5 supporting the upper end of the compression spring 6.

[0030] An L-shaped bracket 8 is fixed on the lifting plate 3. A guide post 7 is vertically slidably mounted on the bracket 8. A compression spring 6 is fitted onto the guide post 7. The upper end of the guide post 7 is fixed to the lower surface of the positioning block 5, and the lower end of the compression spring 6 abuts against the upper surface of the bracket 8.

[0031] Two guide pillars 7 are arranged side by side, and two compression springs 6 are arranged accordingly.

[0032] A telescopic cylinder 13 is fixedly connected to the upper end of the lifting plate 3. The telescopic end of the telescopic cylinder 13 passes through the lifting plate 3 and is fixedly connected to the fixed plate 11.

[0033] A positioning plate 10 is fixedly provided on the fixing plate 11. The positioning plate 10 is located above the carrier belt 1 and close to the upper surface of the side wall of the carrier belt 1.

[0034] Guide posts 12 are fixedly connected side by side on the fixed plate 11, and guide holes matching the guide posts 12 are opened on the lifting plate 3.

[0035] The lifting claw 4 is L-shaped and is located below the carrier belt 1 and close to the lower surface of the side wall of the carrier belt 1.

[0036] The positioning plate 10 has a clearance channel for the clearance lifting claw 4.

[0037] The bracket 8 has a guide hole, and the guide post 7 is slidably connected in the guide hole.

[0038] The lower end of the guide post 7 is provided with a threaded groove, and a limit screw 9 is threadedly connected in the threaded groove. The shank end of the limit screw 9 abuts against the lower surface of the bracket 8.

[0039] The working principle of this device is as follows:

[0040] When the carrier belt 1 is extended and loaded with products, the telescopic cylinders 13 of the carrier belt unloading and loading machine 2 located on both sides of the carrier belt 1 extend simultaneously. Since the telescopic rod is connected to the fixed plate 11, the cylinder body of the telescopic cylinder 13 drives the lifting plate 3 to rise. Because the lifting plate 3 is connected to the positioning block 5, and the height of the positioning block 5 is normally higher than that of the lifting claw 4, the positioning block 5 will first abut against the lower surface of the side wall of the carrier belt 1. The upper surface of the side wall of the carrier belt 1 is limited by the positioning plate 10, thus fixing the carrier belt 1. As the lifting plate 3 continues to rise... The lifting claw 4 abuts against the unloaded carrier belt 1 on one side, opening it up before placing the product in. The positioning block 5 secures the product-loaded carrier belt 1 on one side of the lifting claw 4, preventing the lifting claw 4 from opening and deforming the product-loaded carrier belt 1 along with the unloaded one. The positioning block 5 also secures the product-loaded carrier belt 1 on one side of the lifting claw 4, preventing product damage due to carrier belt 1 deformation, thus improving the product yield.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
