Description

Technical Field

[0001] This utility model relates to the field of baking mold manufacturing, and specifically to a baking mold welding device. Background Technology

[0002] Chinese Patent Application No. 202421917153.8 discloses a laser welding production line for baking molds, including a placement table. The two ends of the placement table are respectively provided with a limiting plate and a first pushing mechanism. A positioning plate is provided between the limiting plate and the first pushing mechanism, extending along the pushing direction of the first pushing mechanism. The limiting plate can move closer to or away from the first pushing mechanism under the action of the sliding table. The first pushing mechanism is used to push the sub-mold or a single sub-mold towards the limiting plate. The placement table is provided with a second pushing mechanism for pushing two sub-molds or a single sub-mold that need to be welded towards the positioning plate. The pushing direction of the second pushing mechanism is perpendicular to the pushing direction of the first pushing mechanism.

[0003] In the above scheme, the movement of the sub-mold on the placement table is achieved through the movement of the limiting plate and the operation of the first pushing mechanism. After welding two adjacent sub-molds, the limiting plate needs to be moved away from the first pushing mechanism under the action of the slide table. Then, the first pushing mechanism pushes the welded sub-mold towards the limiting plate. The next sub-mold is then placed between the first pushing mechanism and the two welded sub-molds. Finally, positioning, clamping, and welding are performed, and this process is repeated to achieve welding and fixing of multiple sub-molds. Each time a sub-mold is welded, the welded sub-mold needs to be pushed on the placement table. The movement distance of the sub-mold each time it is pushed is relatively long, and the contact surface between the sub-mold and the placement table is easily damaged. Moreover, each time positioning and clamping are performed, the limiting plate and the positioning plate are subjected to force, which causes the entire slide table to be stressed. This leads to the use accuracy of the slide table, which has high precision requirements for components, resulting in inaccurate positioning of the sub-molds and a reduction in the service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a baking mold welding device that facilitates the welding of sub-molds, minimizes damage to the surface of the sub-molds, and extends their service life.

[0005] To achieve the above objectives, this utility model employs a baking mold welding device, comprising a welding mechanism and a placement platform. The placement platform is fixed to the output end of a first translation driver. Under the action of the first translation driver, the placement platform moves relative to the welding mechanism along the X direction. A first X-direction positioning block is provided at one end of the placement platform along the X direction, and a first Y-direction positioning block is provided at one end of the placement platform along the Y direction. A second translation driver is provided on the placement platform. An X-direction positioning driver and a Y-direction positioning driver are fixed at the output end of the second translation driver. The X-direction positioning driver and the Y-direction positioning driver move synchronously along the X direction under the action of the second translation driver. A second X-direction positioning block is provided at the output end of the X-direction positioning driver for moving closer to or further away from the first X-direction positioning block, and a second Y-direction positioning block is provided at the output end of the Y-direction positioning driver for moving closer to or further away from the first Y-direction positioning block.

[0006] When using this invention for welding between two sub-molds, it can be used in conjunction with the loading and unloading mechanisms of conventional baking mold welding equipment. The loading mechanism places the first sub-mold on the placement table and brings it close to the first X-axis positioning block and the first Y-axis positioning block. Then, the X-axis positioning driver and the Y-axis positioning driver are activated to cause a slight displacement of the first sub-mold, bringing it into contact with the first X-axis positioning block and the first Y-axis positioning block. Finally, the X-axis positioning driver and the Y-axis positioning driver reset.

[0007] Subsequently, under the action of the first translational driver, the placement platform moves to one side along the X direction by a distance equal to the width of a sub-mold, and under the action of the second translational driver, the X-direction positioning driver and the Y-direction positioning driver move to the other side along the X direction by a distance equal to the width of two sub-molds; the feeding mechanism places the second sub-mold on the placement platform, and then activates the X-direction positioning driver and the Y-direction positioning driver to make the second sub-mold move slightly and fit tightly against the first sub-mold, and then welds the two adjacent sub-molds through the existing welding mechanism;

[0008] After the welding of the first two sub-molds is completed, the placement platform is moved to one side along the X direction by a distance equal to the width of a sub-mold under the action of the first translation driver, and the X-axis positioning driver and the Y-axis positioning driver are moved to the other side along the X direction by a distance equal to the width of a sub-mold under the action of the second translation driver, so as to leave space for the placement of the third sub-mold. The above operation is repeated to place and weld the next sub-mold one by one, thereby realizing the welding of multiple sub-molds. Finally, the entire placement platform is moved away from the welding mechanism under the action of the first translation driver, and the X-axis positioning driver and the Y-axis positioning driver are deviated from the sub-mold on the placement platform under the action of the second translation driver. Finally, the welded sub-mold is unloaded by the unloading mechanism.

[0009] In use, this utility model device moves the placement platform to deviate the movement trajectory of the previously placed sub-mold from the feeding mechanism, thus facilitating the unloading of the subsequent sub-mold. During X-axis and Y-axis positioning and clamping, regardless of the number of sub-molds on the placement platform, the movement of each sub-mold is extremely small. The movement distance of the sub-mold on the placement platform is only related to the feeding accuracy of the feeding mechanism. After welding multiple sub-molds, the placement platform can move the welded sub-mold away from the welding mechanism and closer to the unloading mechanism. This ensures that the relative displacement between the sub-mold and the placement platform is small before and after welding, minimizing friction between the sub-mold surface and the placement platform surface and minimizing damage to the sub-mold surface.

[0010] Furthermore, since both the X-axis positioning driver and the Y-axis positioning driver are mounted on the placement platform, neither the first X-axis positioning block nor the first Y-axis positioning block will transmit force to the connection between the placement platform and the first translation driver after being subjected to force, regardless of whether the X-axis positioning driver or the Y-axis positioning driver is activated. This will prevent damage to the first translation driver and avoid a decrease in its accuracy, thus ensuring the positioning accuracy of the sub-mold, improving the welding effect, and extending the service life of the first translation driver.

[0011] Preferably, the placement platform is provided with a pad for supporting the sub-mold.

[0012] When the sub-mold is placed on the placement table or during welding, minor vibrations or impacts may occur, and the backing plate can act as a buffer to reduce the impact force on the sub-mold and protect it. At the same time, setting up the backing plate can prevent the sub-mold from directly contacting the placement table, and the smooth surface of the backing plate can facilitate the placement, positioning and cleaning of the sub-mold.

[0013] Preferably, the placement platform is provided with a receiving cavity for accommodating the electromagnet assembly, and the pad covers the upper side of the electromagnet assembly. By attracting and fixing the sub-mold with the electromagnet assembly, the fixing effect of the sub-mold can be further guaranteed, preventing lighter sub-molds from tilting or flying out when being pressed and positioned.

[0014] Preferably, the pad is detachably fixed to the placement platform. The X-axis positioning driver and the Y-axis positioning driver move to their extreme positions under the action of the second translation driver, so that the second X-axis positioning block and the second Y-axis positioning block are positioned opposite each other on the side of the pad. This arrangement facilitates the replacement and maintenance of the pad and ensures low friction between the pad and the sub-mold.

[0015] Preferably, the first X-axis positioning block is detachably fixed to the placement platform by fasteners. The first X-axis positioning block can be replaced to accommodate sub-molds of different widths, and also facilitates maintenance and repair of the first X-axis positioning block.

[0016] Preferably, the output end of the second translation driver is fixed with at least two Y-axis positioning drivers arranged side by side, and the second Y-axis positioning block of each Y-axis positioning driver corresponds to a sub-mode.

[0017] This ensures that each sub-mold receives stable and reliable positioning and clamping force in the Y direction, avoiding uneven force distribution or unstable positioning that may occur with a single actuator. As a result, the position of the sub-mold is more stable throughout the welding process, which helps to improve the stability of the welding process and the stability of the welding quality.

[0018] This invention achieves the movement of the sub-mold relative to the welding structure on the placement platform by moving the placement platform, greatly reducing the contact movement between the sub-mold and the placement platform, and has the advantage of minimizing damage to the surface of the sub-mold. Furthermore, since the X-axis and Y-axis positioning drivers are both mounted on the placement platform, they do not exert force on the first translation driver, ensuring the accuracy of the first translation driver. This invention also has the advantage of ensuring the positioning accuracy of the sub-mold, thereby improving the welding effect and extending the service life of the first translation driver.

[0022] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0023] Depend on Figures 1 to 3 As shown, this embodiment discloses a baking mold welding device, including a welding mechanism 100 and a placement platform 1. The placement platform 1 is fixed to the output end of a first translation driver 10. Under the action of the first translation driver 1, the placement platform 1 moves relative to the welding mechanism 100 in the X direction. One end of the placement platform 1 in the X direction is detachably fixed with a first X-direction positioning block 11 by fasteners, and one end of the placement platform 1 in the Y direction is provided with a first Y-direction positioning block 12. The placement platform 1 is provided with a receiving cavity 14 for accommodating an electromagnet assembly 13. A pad 15 covers the upper side of the electromagnet assembly 13 and is used to support the sub-mold to be welded. The pad 15 is detachably fixed to the placement platform 1 by fasteners.

[0024] A second translation driver 20 is fixed on the placement platform 1. An L-shaped movable plate 21 is fixed to the output end of the second translation driver 20. An X-axis positioning driver 3 is fixed to the X-axis side of the movable plate 21, and two Y-axis positioning drivers 4 are fixed to the Y-axis side of the movable plate 21. The X-axis positioning driver 3 and the Y-axis positioning driver 4 move synchronously along the X-axis under the action of the second translation driver 20. The output end of the X-axis positioning driver 3 is provided with a second X-axis positioning block 31 for approaching or moving away from the first X-axis positioning block 11, and the output end of the Y-axis positioning driver 4 is provided with a second Y-axis positioning block 41 for approaching or moving away from the first Y-axis positioning block 12. Each second Y-axis positioning block 41 of the Y-axis positioning driver 4 corresponds to a sub-mold.

[0025] When the X-axis positioning driver 3 and the Y-axis positioning driver 4 move to their limit positions under the action of the second translation driver 20, the second X-axis positioning block 31 and the second Y-axis positioning block 41 are positioned opposite each other on the side of the pad 15. In this embodiment, the first translation driver 10 is a linear motor, the second translation driver is a linear module, and both the X-axis positioning driver 3 and the Y-axis positioning driver 4 are linear cylinders.

[0026] This embodiment achieves the movement of the sub-mold relative to the welding structure on the placement platform by moving the placement platform, which greatly reduces the contact movement between the sub-mold and the placement platform, and has the advantage of minimizing damage to the surface of the sub-mold. Furthermore, since the X-axis positioning driver and the Y-axis positioning driver are both mounted on the placement platform, they do not exert force on the first translation driver, ensuring the accuracy of the first translation driver and the positioning accuracy of the sub-mold, thereby improving the welding effect and extending the service life of the first translation driver.
