Description

Technical Field

[0001] This utility model relates to the technical field of iron can inspection, specifically to a workpiece fixing device for inspecting printed iron cans. Background Technology

[0002] In the metal packaging container manufacturing industry, the printing quality inspection of tin cans is a crucial step in ensuring the product's appearance meets standards. Traditional inspection methods often rely on manual handheld operation or simple clamps to hold the cans, resulting in poor positioning accuracy, susceptibility to movement, and low inspection efficiency, especially when inspecting large batches, making it difficult to guarantee consistency. While some general-purpose fixing devices exist, they often lack designs adapted to the curved surfaces and different sizes of tin cans, leading to issues such as scratching the cans and uneven clamping force during inspection. Furthermore, most fixing devices do not integrate rotation adjustment functions, requiring inspectors to frequently manually adjust the can's position, increasing labor intensity and affecting the accuracy of inspection data. With the industry's increasing demand for automated inspection, developing a dedicated fixing device that is compatible with various can types, provides stable positioning, and is easy to operate is particularly necessary.

[0003] Application number CN201921221468.8 discloses a workpiece fixing device for inspecting printed tin cans, which solves the shortcomings of existing technologies where workpieces are prone to positional displacement during the inspection of printed tin cans, leading to inaccurate inspection. The device includes an inspection table with a workpiece groove. A mating chamber is located on one side of the workpiece groove and is also located on the inspection table. A mounting plate is fixedly installed at the bottom of the mating chamber, and a return spring is fixedly installed on the mounting plate. A locking plate is located at the other end of the return spring. A sliding groove is also provided on the inspection table. This invention uses the return spring to return the locking plate to clamp the workpiece in the workpiece groove, maintaining its stable position and facilitating subsequent inspection. Furthermore, the T-shaped sliding groove and sliding rod ensure that the adjustment plate can only be adjusted along the sliding groove direction, guaranteeing the stability of the overall workpiece fixing operation. However, a drawback is that the single-sided fixing method during clamping has a certain degree of instability, which could lead to the workpiece falling off during subsequent processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 As shown, this utility model is a workpiece fixing device for the inspection of printed iron cans, including a lifting and rotating assembly 1, a locking plate assembly 2 fixedly installed on the top of the lifting and rotating assembly 1, a retraction braking assembly 3 fixedly installed on the top of the locking plate assembly 2, and a clamping assembly 4 connected to the end of the retraction braking assembly 3. The three sets of clamping assemblies 4 are slidably installed on the top of the placement plate assembly 5.

[0028] The retraction braking assembly 3 includes a pneumatic telescopic pump 301, which is fixedly installed at the top center of the limiting base plate 201. A push rod 302 is fixedly installed on the top of the pneumatic telescopic pump 301, and a push plate 303 is fixedly installed on the top of the push rod 302. An mounting plate 304 is fixedly installed around the top of the push plate 303, and a connecting hinge 305 is limited and installed on the outer side of the mounting plate 304.

[0029] By installing a retraction braking assembly 3 on the device, the iron can placed on top can be clamped with one click when using the device, and the surrounding clamping operation makes the fixation more stable.

[0030] The lifting and rotating assembly 1 includes a storage base 101, on which a lifting and rotating motor 102 is fixedly installed, and a limit locking slot 103 is provided around the periphery of the storage base 101.

[0031] The locking plate assembly 2 includes a limiting base plate 201, a locking protrusion 202 fixedly installed around the periphery of the limiting base plate 201, and a support rod 203 fixedly installed on the top periphery of the limiting base plate 201. The locking protrusion 202 is limited and installed inside the limiting locking slot 103. When the storage base 101 is placed in a suitable position, the locking plate assembly 2 is securely connected to the lifting and rotating assembly 1 by limiting and installing the locking protrusion 202 inside the limiting locking slot 103.

[0032] A connecting rod 306 is rotatably mounted on the other side of the connecting hinge 305. When the pneumatic telescopic pump 301 is started, it pushes the push rod 302 upward, which in turn drives the push plate 303 upward. The push plate 303 drives the connecting hinge 305 to move via the mounting plate 304. The connecting hinge 305 rotates, which in turn drives the connecting rod 306 to move within the movable slot 502. The pneumatic telescopic pump 301 operates in the opposite direction, causing the clamping assembly 4 to loosen. The connecting rod 306 and the sliding base 401 reset, and the printed tin can that has been inspected is removed, ready for the next inspection.

[0033] The clamping assembly 4 includes a sliding base 401, which is slidably mounted on the top of the movable slide rail 402. A silicone clamp 403 is fixedly mounted on the inner wall of the sliding base 401, thereby driving the sliding base 401 to slide on the movable slide rail 402, so that the silicone clamp 403 moves toward the printed tin can and clamps it, thereby fixing the workpiece.

[0034] The placement plate assembly 5 includes a workbench 501, which is fixedly installed on the top of the support rod 203. A placement platform 503 is fixedly installed in the middle of the top of the workbench 501. At the same time, a movable slot 502 is opened around the periphery of the workbench 501. A clamping plate movable slot 504 is correspondingly provided around the outer periphery of the placement platform 503. The starting point of the clamping plate movable slot 504 is inside the workbench 501. The workbench 501 is fixedly installed on the top of the support rod 203, completing the installation of the placement plate assembly 5. The printed tin can is placed on the placement platform 503 to prepare for subsequent clamping and fixing.

[0035] A sliding base 401 is provided on the outer bottom of the movable groove 504 of the clamping plate, and a connecting rod 306 is provided inside the movable groove 502 for limiting the movement.

[0036] The end of the connecting hinge 305 is connected to the inside of the sliding base 401 via a limiting rod 3051.

[0037] The workpiece fixing device for printing tin can inspection achieves height adjustment and angle rotation through the lifting and rotating assembly 1, providing different orientations for inspection; the locking plate assembly 2 is used to securely connect the lifting and rotating assembly 1 and the retraction braking assembly 3; the retraction braking assembly 3 uses the power generated by the pneumatic telescopic pump 301, which is transmitted through components such as the push rod 302 and the push plate 303 to drive the clamping assembly 4 to move; the silicone clamp 403 of the clamping assembly 4 achieves stable clamping of the printing tin can; the placement plate assembly 5 provides support and movement space for the entire fixing and inspection process. All components cooperate with each other to complete the fixing and inspection preparation work for the printing tin can. During the operation, the storage base 101 is first placed in a suitable position and limited by the locking protrusion 202 installed in the limiting locking slot 103, thus securely connecting the locking plate assembly 2 and the lifting and rotating assembly 1. Simultaneously, the workbench 501 is fixedly installed on the top of the support rod 203, completing the installation of the placement plate assembly 5. The printed tin can is placed on the placement table 503 to prepare for subsequent clamping and fixing. The pneumatic telescopic pump 301 is started, which pushes the push rod 302 upward. The push rod 302 drives the push plate 303 upward. The push plate 303 drives the connecting hinge 305 to move through the mounting plate 304. The connecting hinge 305 rotates, driving the connecting rod 306. The connecting rod 306 moves within the movable slot 502, thereby driving the sliding base 401 to move. The sliding rail 402 slides, causing the silicone clamp 403 to move toward and clamp the printed tin can, thus fixing the workpiece. According to the testing requirements, the lifting and rotating motor 102 is started, driving the entire device to lift and rotate, adjusting the printed tin can to a suitable testing position and angle. After completing the above operations, the fixed printed tin can is tested. After the test is completed, the pneumatic telescopic pump 301 operates in reverse, causing the clamping assembly 4 to release, the connecting rod 306 and the sliding base 401 to reset, and the tested printed tin can is removed, ready for the next test.
