Description

Technical Field

[0002] Magnetic steel is mainly used in various fields such as sensors, instruments, electronics, electromechanics, medical treatment, teaching, automobiles, and aviation technology. Depending on the metal composition of the magnetic steel, its magnetic properties will be different, and thus its uses will also be different. At present, magnetic steel is generally manufactured by powder metallurgy, and in order to improve production efficiency, in the manufacturing process, it is usually first processed into long strips, and then the magnetic strips are cut and segmented according to the actual required length; in order to improve cutting efficiency, multiple magnetic strips are usually stacked and then cut at the same time, and glue is applied to adjacent magnetic strips when stacking to ensure that the stacked magnetic strips will not deviate when cutting.

[0003] At present, glue is generally applied to the magnets one by one using a manual handheld glue gun, and then the glued magnets are stacked on the corresponding material tray with the glue facing downward. When the material tray is filled with magnets according to the set requirements, it is transferred to the next station. This manual gluing method is not only inefficient and labor-intensive, but also causes uneven glue application, and the stacking position on the material tray cannot be accurate and consistent, which to a certain extent affects the smooth progress of the next process.

[0004] With the innovation of technology, some automatic gluing equipment has also appeared. In the automatic gluing process, the workpieces on the conveying mechanism are generally clamped and moved to the glue spraying station by a special clamping mechanism for glue spraying, and then stacked on the collection board in order. In the prior art, when the workpieces are stacked on the collection board, due to the presence of glue on the lower surface of the workpieces, the position of the workpieces is prone to slip under the action of the liquid surface tension of the glue, resulting in inaccurate final stacking position of the workpieces.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 , 2 As shown, the utility model provides a clamping mechanism, which includes a mounting plate 1 and a driving component for driving the mounting plate 1 to rise and fall. Specifically, the driving component here is one of a pneumatic cylinder, an oil cylinder or an electric push cylinder 22. In this embodiment, the electric push cylinder 22 is preferred, and the driving force is stable and reliable, and does not require an air source or hydraulic oil. It is relatively more environmentally friendly and easy to control.

[0029] In addition, the mounting plate 1 in the above structure is an L-shaped structure, wherein the horizontal plate of the mounting plate 1 is connected to the free end of the electric push cylinder 22, and a linear guide rail 16 extending along its axial direction is also provided on the outer wall of the electric push cylinder 22, and the vertical plate of the mounting plate 1 is connected to the slider of the linear guide rail 16, which fully ensures the smoothness of the lifting and lowering of the mounting plate 1.

[0030] In this embodiment, a limiting assembly is further provided on the mounting plate 1, and the limiting assembly can move between a first position and a second position in a vertical direction, and, in the first position, the lower end surface of the limiting assembly is higher than the lower end surface of the suction cup 10 assembly, so that the suction cup 10 assembly will not interfere with the workpiece when adsorbing it, thereby ensuring that the workpiece is stably adsorbed; in the second position, the lower end surface of the limiting assembly is pressed down to be flush with the lower end surface of the workpiece, so as to locate the stacking position of the workpiece, thereby ensuring that the final stacking position of the workpiece is accurate and not easily offset.

[0031] In the above structure, more specifically, Figure 3As shown, the limit assembly includes a first driving cylinder 2 and a second driving cylinder 3 vertically connected to the mounting plate 1; a limit baffle 4 is connected to the piston rod of the first driving cylinder 2, a horizontally arranged third driving cylinder 5 is connected to the piston rod of the second driving cylinder 3, and a limit pressure plate 6 is connected to the piston rod of the third driving cylinder 5, and the limit baffle 4 and the limit pressure plate 6 are respectively located at the front and rear sides of the suction cup 10 assembly; when the suction cup 10 assembly drives the workpiece to move to the set stacking position on the collecting plate 21, the suction cup 10 assembly does not withdraw first and continues to maintain the adsorption state; the first driving and the third driving cylinders are connected to the limit baffle plate 4, and the limit pressure plate 6 is connected to the piston rod of the third driving cylinder 5, and the limit baffle plate 4 and the limit pressure plate 6 are respectively located at the front and rear sides of the suction cup 10 assembly; when the suction cup 10 assembly drives the workpiece to move to the set stacking position on the collecting plate 21, the suction cup 10 assembly does not withdraw first and continues to maintain the adsorption state; The two driving cylinders 3 extend downward at the same time, driving the limit baffle 4 and the limit pressure plate 6 to move downward until they are in contact with the collecting plate 21 or the upper end surface of the workpiece, and then the third driving cylinder 5 drives the limit pressure plate 6 to be pressed against the rear end of the workpiece, and at the same time ensures that the front end of the workpiece is in contact with the limit baffle 4; the front and rear positions of the workpiece are fully positioned by the limit baffle 4 and the limit pressure plate 6, and then the adsorption force of the suction cup 10 assembly is released, and then the third driving cylinder 5 drives the limit pressure plate 6 to reset, and finally the first driving cylinder 2 and the second driving cylinder 3 reset upward to ensure that the workpiece is stacked accurately and not offset.

[0032] In this embodiment, a horizontally arranged connecting plate 7 is connected to the piston rod of the first driving cylinder 2, and the front end of the connecting plate 7 is bent downward to form a limit baffle 4; in addition, a positioning side plate 8 perpendicular to the limit baffle 4 is connected to the right side of the connecting plate 7, which is used to limit the position of the left side wall of the workpiece, further ensuring the accuracy of the workpiece stacking position. In this structure, the position where the suction cup 10 adsorbs the workpiece is basically adsorbed according to the set position, and the right side of the positioning side plate 8 is set at a position level with the left side of the workpiece, that is, to ensure that the left side wall of the workpiece is limited. Of course, in other embodiments, a structure for positioning the right side of the workpiece can be further set on the mounting plate 1.

[0033] More specifically, in the above structure, the connecting plate 7 is an L-shaped structure as a whole when viewed from top to bottom, that is, the vertical plate of the connecting plate 7 is located on the left side of the suction cup 10 assembly, the horizontal plate of the connecting plate 7 is located on the front side of the suction cup 10 assembly, and the front end of the horizontal plate is bent downward to form a wider limit baffle 4; in addition, after such an arrangement, the first drive cylinder 2 is located on the left side of the horizontal plate of the mounting plate 1, and the second drive cylinder 3 is located on the rear side of the horizontal plate of the mounting plate 1.

[0034] In addition, the suction cup 10 assembly includes a suction cup mounting block 9 connected to the lower end of the mounting plate 1, and multiple suction cups 10 are connected to the lower end surface of the suction cup mounting block 9. An air inlet connector 11 connected to each suction cup 10 is provided on the side wall of the suction cup mounting block 9, and the right side edge of the positioning side plate 8 is flush with the left side edge of the suction cup mounting block 9; in this structure, when the initial position of the suction cup 10 assembly is set, the left side wall of the adsorbed workpiece is flush with the left side wall of the suction cup mounting block 9, thereby ensuring that during the downward process of the positioning side plate 8, it basically slides along the left side wall of the workpiece, thereby ensuring the positioning of the left side of the workpiece.

[0035] In this embodiment, Figure 4 As shown, a movable plate 12 is provided on the connecting plate 7 and can slide along the front-rear direction thereof. Figure 3 As shown, a guide plate 23 extending upward is provided at the rear end of the right side of the connecting plate 7, and a first guide slot 24 is provided on the right side of the guide plate 23, and a waist-shaped hole extending in the front-to-back direction is provided on the bottom plate of the first guide slot 24, and the movable plate 12 is slidably fitted in the first guide slot 24, and the position of the movable plate 12 is fixed by connecting the fastening bolts in the waist-shaped hole; similarly, a second guide slot 25 extending in the left-right direction is connected below the front end of the movable plate 12, and the left end of the positioning side plate 8 is slidably fitted in the second guide slot 25, and a waist-shaped hole extending in the left-right direction is provided on the positioning side plate 8, and the position of the positioning side plate 8 is fixed by connecting the fastening bolts in the waist-shaped hole; more specifically, the right end of the positioning side plate 8 in this structure is provided with a bending portion 26 extending vertically downward, and the right side wall of the bending portion 26 is slidably fitted with the left side wall of the suction cup mounting block 9, which has a better positioning effect on the left side wall of the workpiece.

[0036] In addition, in order to ensure the accuracy of the suction cup 10 adsorbing the workpiece position, as Figure 4 As shown, a fixing block 13 is connected to the lower end of the mounting plate 1, and a positioning groove 14 extending in the front-to-back direction is provided on the lower end surface of the fixing block 13, and a positioning protrusion 15 slidingly matched with the positioning groove 14 is provided on the upper end of the suction cup mounting block 9, and a fastening screw for fixing the positioning protrusion 15 is penetrated on the side wall of the fixing block 13, so that the front-to-back position of the suction cup mounting block 9 can be precisely adjusted. Preferably, the cross section of the positioning groove 14 is a T-shaped structure, and the shape of the positioning protrusion 15 matches the structure of the positioning groove 14.

[0037] In this embodiment, Figure 1As shown, a fourth drive cylinder 17 vertically arranged is also connected to the mounting plate 1, and a positioning plate 18 is connected to the piston rod of the fourth drive cylinder 17. The positioning plate 18 is provided with a positioning hole for the glue spraying hose to be inserted and matched. After such arrangement, the glue spraying hose can also be integrated on the clamping mechanism. When stacking the workpieces, there is no need to move the workpieces to a specific glue spraying station for glue spraying like a traditional gluing machine, and then transfer and stack them on the collecting plate 21. The clamping mechanism in this structure clamps the workpiece from the conveying component and then moves it directly to the top of the collecting plate 21. The glue spraying hose on the positioning plate 18 first sprays glue on the stacking position of the workpiece, and then the workpiece is stacked to the corresponding position. In addition, the position can be limited by the limit baffle 4, the limit pressure plate 6 and the positioning side plate 8 during stacking, thereby effectively ensuring the accuracy of the stacking position of the workpiece.

[0038] On the other hand, Figure 5 As shown, the utility model also provides a block automatic gluing machine, including a frame 19, on which a conveyor belt assembly 20, a collecting plate 21 and the aforementioned clamping mechanism with a positioning function are arranged, and the clamping mechanism is used to clamp the workpiece on the conveyor belt assembly 20, and maintain an accurate position to stack it on the collecting plate 21. More specifically, in this embodiment, collecting plates 21 are arranged on both sides of the conveyor belt assembly 20 on the frame 19, and a gantry is arranged on the frame 19, and two clamping mechanisms are connected to the gantry, which are used to clamp and stack the workpieces on the conveyor belt assembly 20 on the corresponding collecting plate 21 one by one, that is, a double-station clamping structure, to improve the gluing stacking effect.

[0039] In addition, the first drive cylinder 2, the second drive cylinder 3, the third drive cylinder 5 and the fourth drive cylinder 17 involved in the description of this embodiment are all pneumatic cylinders; of course, in other embodiments, they can also be oil cylinders or electric push cylinders 22.

[0040] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto.
