[0025] The following is a detailed description of a mask plate metal strip positioning, locking, and translation device provided in an embodiment of the present invention, with reference to the accompanying drawings.

[0026] Example:

[0027] Figure 1 This illustration shows one of the three-dimensional structural schematic diagrams of the mask plate metal strip positioning, locking, and translation device provided in an embodiment of the present invention; Figure 2 1. A three-dimensional structural schematic diagram of the positioning and locking unit provided in an embodiment of the present invention is shown; 2. A second three-dimensional structural schematic diagram of the mask metal strip positioning and locking translation device provided in an embodiment of the present invention is shown. Figure 4 A top view of the mask plate metal strip positioning and locking translation device provided in an embodiment of the present invention is shown; Figure 5 The image shows a front view of the mask plate metal strip positioning, locking, and translation device provided in an embodiment of this utility model. (See image below.) Figures 1 to 5As shown in the figure, the present invention provides a mask metal strip positioning, locking, and translation device, which is used to position and tighten metal strips during the stamping process and can adapt to metal strips of different lengths and specifications. It features high automation, good adaptability, and high positioning accuracy. The mask metal strip positioning, locking, and translation device includes: a drive mechanism 1, a transmission mechanism 2, and a positioning and locking unit 3. The drive mechanism 1 includes a drive motor 101, and the transmission mechanism 2 includes: a lead screw 201, a lead screw nut 202, and a traveling bracket 203. The lead screw nut 202 is connected to the lead screw 201 via a transmission engagement, and the lead screw nut 202 and the lead screw 201 are connected by a thread, allowing the lead screw nut 202 to move linearly along the central axis of the lead screw 201, achieving high transmission accuracy. The machine 101 is driven to one end of the lead screw 201 in the transmission mechanism 2 to realize the servo rotation of the lead screw 201. The drive motor 101 drives the lead screw 201 to perform servo rotation. The walking bracket 203 is mechanically fixed on the lead screw nut 202 to realize the linear movement of the walking bracket 203. The walking bracket 203 and the lead screw nut 202 move linearly synchronously along the lead screw 201. The positioning and locking unit 3 is mechanically fixed on the walking bracket 203 and moves linearly synchronously with the walking bracket 203. It is used to position and press metal strips of different specifications. When the length of the metal strip changes or when feeding is required, the positioning and locking unit 3 moves linearly along the lead screw 201 under the drive of the drive motor 101 and the drive of the walking bracket 203 to press one end of the metal strip so that the metal strip maintains sufficient tension.

[0028] In the mask plate metal strip positioning, locking, and translation device provided in this embodiment of the utility model, specifically, the positioning and locking unit 3 includes: a pressing cylinder 301, a positioning cylinder 302, a pressing block 303, and a positioning block 304. The positioning block 304 is connected to the positioning cylinder 302, and the pressing block 303 is connected to the pressing cylinder 301 to realize the up-and-down movement of the pressing block 303 and, together with the positioning block 304, lock one end of the metal strip. The pressing cylinder 301 and the positioning cylinder 302 cooperate to operate. When the positioning cylinder 302 rises, it applies an upward force to the metal strip through the positioning block 304; when the pressing cylinder 301 descends, it applies a downward force to the metal strip through the pressing block 303, thereby realizing the pressing block 303 and the positioning block 304 pressing the metal strip, thus fixing the metal strip. The positioning and locking unit 3 can move along the central axis of the lead screw 201 to accommodate the fixing of metal strips of different lengths. When the length of the metal strip changes, the pressure block 303 of the positioning and locking unit 3 can move linearly to adapt to the change in the length of the metal strip. The pressure block 303 of the positioning and locking unit 3 can work together with the positioning block 304 of the positioning cylinder 302 to clamp the metal strip, prevent the metal strip from shifting, and keep the metal strip under sufficient tension for punching and other operations.

[0029] In a mask plate metal strip positioning, locking, and translation device provided in this embodiment of the utility model, more specifically, the transmission mechanism 2 further includes: a slide rail 206 and a slider 207. The two slide rails 206 are arranged in parallel on the workbench or the ground. The walking bracket 203 is connected to the slide rails 206 through several sliders 207 below it to achieve positioning and guidance of the walking bracket 203. Each slide rail 206 is provided with at least one slider 207, so that the walking bracket 203 moves smoothly along the direction of the slide rail 206, playing a good positioning and guiding role. At the same time, the slide rails 206 and sliders 207 are used to support the walking bracket 203, so as to reduce the force on the lead screw 201, prevent the lead screw 201 from deforming under stress, and ensure the transmission and positioning accuracy of the transmission mechanism 2.

[0030] In a mask plate metal strip positioning and locking translation device provided in this embodiment of the utility model, more specifically, the transmission mechanism 2 further includes: a first support 204 and a second support 205. The first support 204 and the second support 205 are respectively located at both ends of the lead screw 201 and are connected to the lead screw 201 by shaft hole engagement to realize the support and positioning of the lead screw 201, so that the lead screw 201 rotates on the first support 204 and the second support 205, which also realizes the support and positioning of both ends of the lead screw 201.

[0031] In a mask plate metal strip positioning and locking translation device provided in this embodiment of the utility model, as a further design improvement, it also includes: limiting blocks 4. Several limiting blocks 4 are set at both ends of the slide rail 206 to limit the travel of the walking bracket 203 and prevent the walking bracket 203 from moving out of the working area. In this embodiment of the utility model, two limiting blocks 4 are respectively set on both sides of the walking bracket 203. Here, there is no specific limitation on the number of limiting blocks 4, as long as it can meet the user's needs.

[0032] The mask plate metal strip positioning and locking translation device provided in this embodiment of the utility model further includes, as a design improvement: at least one sensor 5, which is disposed below the traveling bracket 203 to detect the position of the transmission mechanism 2, and to timely determine and correct the moving distance and position of the traveling bracket 203, thereby further ensuring the positioning accuracy of the punching point; preferably, the sensor 5 is disposed between two slide rails 206, and one or more sensors can be used to facilitate position detection of the traveling bracket 203. Preferably, the sensor 5 is configured as a proximity switch, which fully utilizes its advantages of good economy, fast response speed, and wide applicability.

[0033] As a further design improvement, the mask metal strip positioning and locking translation device provided in this embodiment of the utility model also includes: a first telescopic cover 208 and a second telescopic cover 209. The first telescopic cover 208 and the second telescopic cover 209 are mechanically connected to both sides of the walking bracket 203 to realize the internal protection of the transmission mechanism 2. At the same time, the first telescopic cover 208 and the second telescopic cover 209 can move with the walking bracket 203, and the length of the first telescopic cover 208 and the second telescopic cover 209 can be freely extended and retracted to prevent dust or other contaminants from affecting the moving parts of the transmission mechanism 2, thereby further improving the working reliability of the mask metal strip positioning and locking translation device.

[0034] In the mask plate metal strip positioning and locking translation device provided in this embodiment of the utility model, as a further design improvement, the drive mechanism 1 also includes a motor cover 102. The motor cover 102 is arranged around the drive motor 101 to protect the drive motor 101, prevent the drive motor 101 from being bumped, and improve the working safety and reliability of the drive motor 101.

[0035] Compared with the prior art, the mask plate metal strip positioning, locking and translation device provided in this embodiment of the utility model is reasonably designed. The positioning and locking unit 3 is driven to move linearly by the joint action of the drive motor 101 and the transmission mechanism 2. The positioning and locking unit 3 is used to fix the metal strip, which ensures the normal operation of other processes in the production line and the accuracy of metal strip positioning. This embodiment of the utility model has a high degree of automation, good adaptability and versatility, can adapt to metal strips of various specifications, operates reliably, improves work efficiency, and meets the specific needs of users.
