[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Example 1

[0024] Please see Figure 1-4The present invention provides the following technical solution: a special fixture for a palletizing robot, including a mounting frame 1, a support plate 2 mounted on the top of the mounting frame 1, a gear 3 mounted on the top surface of the support plate 2, a toothed plate 4 meshing on one side surface of the gear 3, a cylinder 5 mounted on one side of the toothed plate 4, a motor 7 mounted on one side surface of the mounting frame 1, a screw 10 with positive and negative threads connected to the output end of the motor 7, a clamping plate 6 threadedly connected to the surface of the screw 10, a dust removal component 8 installed inside the mounting frame 1, and a limit component 9 fixedly connected to the bottom surface of the mounting frame 1.

[0025] Specifically, the dust removal assembly 8 includes an air inlet 81, a dust collection box 82, a filter frame 83, a limiting block 84, an air inlet pipe 85, a jet nozzle 86, an air outlet pipe 87, and an air pump 88. The dust collection box 82 is installed inside the mounting frame 1. The limiting block 84 is installed inside the dust collection box 82. The filter frame 83 is installed on the top of the limiting block 84. The air inlet 81 is opened on the top of the filter frame 83. The air pump 88 is installed at the bottom of the filter frame 83. The air inlet pipe 85 is provided between the air pump 88 and the filter frame 83. The air outlet pipe 87 is fixedly connected to one side of the air pump 88. The jet nozzle 86 is fixedly connected to one side of the air outlet pipe 87.

[0026] By adopting the above technical solution, when using the dust removal component 8, external air is drawn into the dust removal box 82 by the air pump 88, and impurities and dust in the air are filtered by the filter frame 83. Then, the air is finally sprayed out from the air jet nozzle 86 through the air outlet pipe 87. The sprayed gas can effectively remove dust from the surface of the clamping plate 6, thereby avoiding the problem of items falling off the clamping plate 6 when it is transported due to reduced friction between the clamping plate 6 and the items caused by dust adhering to the surface of the clamping plate 6, thus improving safety. The filter frame 83 can be pulled out by the handle on one side of the dust removal box 82, which is convenient for cleaning the dust in the filter frame 83, thereby enhancing practicality. The direction of the air jet can be adjusted by the air jet nozzle 86 to facilitate dust removal at different positions of the clamping plate 6, which also enhances practicality.

[0027] Specifically, a handle is fixed to one side of the filter frame 83, and a protective net is installed inside the air inlet 81.

[0028] By adopting the above technical solution, the filter frame 83 can be easily pulled out by the handle to clean the dust in the filter frame 83, and the protective net can protect the filter frame 83 and prevent large foreign objects from entering the dust collection box 82.

[0029] In this embodiment, when using the dust removal assembly 8, external air is drawn into the dust removal box 82 by the air pump 88. Impurities and dust in the air are filtered by the filter frame 83. The air is then ejected from the air outlet 86 through the air outlet pipe 87. The ejected gas effectively removes dust from the surface of the clamping plate 6, thus preventing the clamping plate 6 from falling off during transport due to reduced friction caused by dust adhering to its surface. This improves safety. The filter frame 83 can be pulled out using a handle on one side of the dust removal box 82 for easy cleaning of the dust inside, enhancing practicality. The direction of the air jet can be adjusted via the air outlet 86 to facilitate dust removal at different locations on the clamping plate 6, further enhancing practicality. The filter frame 83 is protected by a protective net, which also prevents larger foreign objects from entering the dust removal box 82.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that, specifically, the limiting component 9 includes a mounting plate 91, a screw 92, a limiting rod 93, a bottom support component 94, an anti-slip block 95, a limiting plate 96, a support block 97, and a fixing plate 98. The mounting plate 91 is installed at the bottom of the mounting frame 1. The fixing plates 98 are fixed to both sides of the mounting plate 91. The support block 97 is fixed to one side of the fixing plate 98. The screw 92 passes through the interior of the support block 97. The limiting plate 96 is threadedly connected to the surface of the screw 92. The limiting rod 93 is fixed to one side of the limiting plate 96. The anti-slip block 95 is provided on one side of the limiting plate 96. The bottom support component 94 is installed at the bottom of the limiting plate 96.

[0032] By adopting the above technical solution, when using the limiting component 9, the items to be stacked are first clamped and fixed by the clamping plate. Then, the handwheel is turned to drive the screw 92 to rotate, so that the limiting plate 96 gradually comes closer to the items. When the limiting plate 96 can clamp and limit the other two sides of the items, the anti-slip block 95 can increase the friction between the limiting plate 96 and the items, so that the limiting is more stable. At the same time, the bottom support component 94 can also support the items, making the items more secure and stable during transportation. It also avoids the problem of items falling due to insecure clamping, further improving the clamping effect of the fixture and enhancing its practicality.

[0033] Specifically, the mounting plate 91 has mounting screw holes inside, and the mounting bracket 1 has mounting bolts on its top surface.

[0034] By adopting the above technical solution, the installation of the component can be facilitated by the cooperation of the mounting bolts and mounting screw holes, and the maintenance of the component is also more convenient, thus enhancing its practicality.

[0035] Specifically, the bottom support assembly 94 includes a cavity 941, a locking block 942, a spring 943, a locking groove 944, a bottom support plate 945, and an extension plate 946. The extension plate 946 is provided inside the limiting plate 96, the cavity 941 is provided inside the extension plate 946, the spring 943 is provided inside the cavity 941, the locking block 942 is provided on one side surface of the spring 943, the bottom support plate 945 is fixedly connected to the bottom surface of the extension plate 946, and the locking groove 944 is provided at the contact point between the locking block 942 and the limiting plate 96.

[0036] By adopting the above technical solution, when using the bottom support component 94, first press the locking block 942 to disengage the locking block 942 from the slot 944, thereby pulling the extension plate 946 to adjust the position of the bottom support plate 945, thus expanding the applicability of the clamp. The soft pad on the top surface of the bottom support plate 945 can reduce the impact on the items. After use, press the locking block 942 again to reset the extension plate 946 into the limiting plate 96, saving space and facilitating other work.

[0037] In this embodiment, when using the limiting component 9, the items to be stacked are first clamped and fixed by the clamping plate. Then, the handwheel is turned to drive the screw 92 to rotate, so that the limiting plate 96 gradually comes closer to the items. When the limiting plate 96 can clamp and limit the other two sides of the items, the anti-slip block 95 can increase the friction between the limiting plate 96 and the items, thus making the limiting more stable. At the same time, the bottom support component 94 can also support the items, making the items more secure and stable during transportation. It also avoids the problem of items falling due to insecure clamping, further improving the clamping effect of the fixture and enhancing its effectiveness. For practicality, the mounting bolts and screw holes facilitate the installation of the component, and also make maintenance easier, enhancing its usability. When using the bottom support component 94, first press the locking block 942 to disengage it from the slot 944, thereby pulling the extension plate 946 to adjust the position of the bottom support plate 945, thus expanding the applicability of the clamp. The soft pad on the top surface of the bottom support plate 945 reduces impact on the items. After use, press the locking block 942 again to return the extension plate 946 to the inside of the limiting plate 96, saving space and facilitating other work.

[0038] The structure and operating principle of the mounting frame 1, support plate 2, gear 3, toothed plate 4, cylinder 5, clamping plate 6, motor 7 and positive and negative threaded screw 10 in this utility model have been disclosed in a special fixture for a palletizing robot disclosed in Chinese patent application number 202421115360.1.

[0039] The working principle and usage process of this utility model: This utility model adjusts a special gripper for a palletizing robot. When using the dust removal component 8, external air is drawn into the dust removal box 82 by the air pump 88. Impurities and dust in the air are filtered by the filter frame 83. Then, the air is ejected from the air outlet 86 through the air outlet pipe 87. The ejected gas can effectively remove dust from the surface of the clamping plate 6, thereby preventing the clamping plate 6 from falling off during the transfer of items due to reduced friction caused by dust adhering to its surface. Safety is improved by allowing the filter frame 83 to be pulled out via a handle on one side of the dust collection box 82, facilitating dust removal and enhancing practicality. The jet nozzle 86 allows for adjustment of the jet direction, enabling dust removal at different locations on the clamping plate 6. The handle facilitates the removal of the filter frame 83 for cleaning, and the protective net protects the filter frame 83 while preventing larger foreign objects from entering the dust collection box 82. This invention adjusts a special clamp for a palletizing robot, specifically for the use of the limiting component 9. First, the items to be stacked are clamped and fixed using the clamping plate. Then, the handwheel is turned to rotate the screw 92, causing the limiting plate 96 to gradually approach the items. When the limiting plate 96 can clamp and limit the other two sides of the items, the anti-slip block 95 increases the friction between the limiting plate 96 and the items, making the limiting more stable. At the same time, the bottom support component 94 can support the items, making them more secure and stable during transportation. This also prevents items from falling due to insecure clamping, further improving the clamping effect of the fixture and enhancing its practicality. The fit between the bolts and mounting holes facilitates the installation of the component and makes maintenance easier, enhancing its practicality. When using the bottom support component 94, first press the locking block 942 to disengage it from the slot 944, thereby pulling the extension plate 946 to adjust the position of the bottom support plate 945, thus expanding the applicability of the clamp. The soft pad on the top surface of the bottom support plate 945 reduces impact on the items. After use, press the locking block 942 again to return the extension plate 946 to the inside of the limiting plate 96, saving space and facilitating other work.
