[0034] As Figure 2 and Figure 3 shown, an embodiment of a mandrel pressing device of the present invention includes a frame 2, a product positioning mechanism 3, a pressing mechanism 4, a heating mechanism 5, a lifting drive mechanism 6, and a translation drive mechanism 7. The product positioning mechanism 3 is arranged on the frame 2, and the pressing mechanism 4 is arranged on the frame 2. Specifically, the translation drive mechanism 7 is arranged on the frame 2, the lifting drive mechanism 6 is arranged on the translation drive mechanism 7, and the pressing mechanism 4 is arranged on the lifting drive mechanism 6, that is, the pressing mechanism 4 is arranged on the frame 2 through the lifting drive mechanism 6 and the translation drive mechanism 7. The product positioning mechanism 3 is used to install and position the product 1. The pressing mechanism 4 includes a pressing drive mechanism 41 and a pressing part 42 (please refer to Figure 8 shown). The pressing drive mechanism 41 is arranged on the frame 2. Specifically, the translation drive mechanism 7 is arranged on the frame 2, the lifting drive mechanism 6 is arranged on the translation drive mechanism 7, and the pressing drive mechanism 41 is arranged on the lifting drive mechanism 6, that is, the pressing drive mechanism 41 is arranged on the frame 2 through the lifting drive mechanism 6 and the translation drive mechanism 7. The pressing part 42 is arranged on the pressing drive mechanism 41. The pressing drive mechanism 41 is used to drive the pressing part 42 to move towards the mandrel mounting groove 121 on the product 1 installed and positioned on the product positioning mechanism 3 and press the mandrel into the mandrel mounting groove 121. Due to the above technical solution, the mandrel pressing device of the present invention has the advantages of good pressing stability and being very labor-saving. The mandrel pressing device of the present invention is used to press and bond the mandrel into the mandrel mounting groove 121 on the product 1. Before using the mandrel pressing device of the present invention to press the mandrel, glue is dotted on one side of the circumferential surface of the mandrel. The product 1 is installed and fixed on the product positioning mechanism 3. The side of the mandrel with glue is facing the mandrel mounting groove 121 and the mandrel is pressed into the mandrel mounting groove 121, and a cushion block 8 is placed on the product 1 (please refer to Figure 1As shown in the figure, the spacer block 8 is abutted against the mandrel to keep the mandrel in the mandrel mounting groove 121. The pressing drive mechanism 41 drives the pressing portion 42 to move towards the mandrel mounting groove 121 on the product 1 mounted and positioned on the product positioning mechanism 3, and presses the mandrel in the mandrel mounting groove 121. After the glue on the mandrel is cured, the bonding and fixing of the mandrel in the mandrel mounting groove 121 is completed. It can be understood that the heating mechanism 5, the lifting drive mechanism 6 and the translation drive mechanism 7 are not essential structures of the present invention. For example, in some embodiments, a mandrel pressing device of the present invention may only include a frame 2, a product positioning mechanism 3 and a pressing mechanism 4, and the pressing mechanism 4 is directly connected to the frame 2, that is, the pressing drive mechanism 41 is directly connected to the frame 2.

[0035] The frame 2 includes a main support frame 21, a seat plate 22 horizontally arranged on the main support frame 21, a housing 23 arranged on the seat plate 22 and having an opening 231 for the mandrel and the product 1 to be placed therein, and a secondary support frame 24 arranged on the seat plate 22 and located inside the housing 23. The housing 23 is not an essential component of the present invention. In some embodiments, the frame 2 may only include the main support frame 21, the seat plate 22 and the secondary support frame 24.

[0036] As Figure 4As shown, the product positioning mechanism 3 includes a support base 31, a positioning portion 32, a fixing portion 33, and a pushing mechanism 34. The support base 31 is disposed on the frame 2. Specifically, the support base 31 is disposed on the seat plate 22. The support base 31 is located below the pressing portion 42. The positioning portion 32 is disposed on the support base 31 and is used for positioning the product 1. The fixing portion 33 is disposed on the support base 31 and is used for supporting and fixing the product 1. The support base 31 is connected to the frame 2 through the pushing mechanism 34. Specifically, the support base 31 is connected to the seat plate 22 through the pushing mechanism 34. The pushing mechanism 34 is used for driving the support base 31 to move towards the opening 231 so that the support base 31 moves to the position of the opening 231, and the pushing mechanism 34 is also used for driving the support base 31 to move away from the opening 231 so that the support base 31 moves below the pressing portion 42. The positioning portion 32 positions the product 1 so that the product 1 is located at an accurate position on the support base 31. The fixing portion 33 supports and fixes the product 1 so that the product 1 is stably fixed on the support base 31. In this way, the product positioning mechanism 3 can achieve the installation and positioning of the product 1. Before positioning and fixing the product 1 on the support base 31, the pushing mechanism 34 is used to drive the support base 31 to move towards the opening 231, making the support base 31 closer to the opening 231, which is more convenient for positioning and fixing the product 1 on the support base 31, for fitting the mandrel into the mandrel mounting groove 121, and for placing the spacer 8 on the product 1 so that the spacer 8 abuts against the mandrel to keep the mandrel in the mandrel mounting groove 121. After completing the positioning and fixing of the product 1 and keeping the mandrel in the mandrel mounting groove 121, the pushing mechanism 34 is used to drive the support base 31 to move away from the opening 231 so that the support portion moves below the pressing portion 42, facilitating the pressing portion 42 to press the mandrel in the mandrel mounting groove 121. It can be understood that the pushing mechanism 34 is not an essential structure of the product positioning mechanism 3. For example, in some embodiments, the product positioning mechanism 3 may only include the support base 31 and the positioning portion 32 and the fixing portion 33 disposed on the support base 31, and the support base 31 is directly fixed on the seat plate 22.

[0037] The support base 31 includes a bottom plate 311, a top plate 312, a connecting rod 313, and a baffle 314. The bottom plate 311 is disposed on the seat plate 22. Specifically, the pushing mechanism 34 is disposed on the seat plate, and the bottom plate 311 is disposed on the pushing mechanism 34, that is, the bottom plate 311 is disposed on the seat plate 22 through the pushing mechanism 34. The top plate 312 is disposed above the bottom plate 311. There are four connecting rods 313, and the connecting rods 313 are used to connect the top plate 312 and the bottom plate 311. The baffle 314 is disposed on one side of the top plate 312 and the bottom plate 311 facing the opening 231, and the baffle 314 is used to cover the gap between the top plate 312 and the bottom plate 311. It can be understood that in other embodiments, the number of the connecting rods 313 can also be other numbers.

[0038] The positioning portion 32 includes a first positioning member 321, a second positioning member 322, and a third positioning member 323. There are two first positioning members 321, and the two first positioning members 321 are disposed on the top plate 312 at positions corresponding to the second edge 112 of the main board 11. There are two second positioning members 322, and the two second positioning members 322 are disposed on the top plate 312 at positions corresponding to the third edge 113 of the main board 11. There are two third positioning members 323, and the two third positioning members 323 are disposed on the top plate 312 at positions corresponding to the fourth edge 114 of the main board 11. When positioning the product 1, the product 1 is located within the range surrounded by the first positioning member 321, the second positioning member 322, and the third positioning member 323, and the second edge 112 abuts against the first positioning member 321, the third edge 113 abuts against the second positioning member 322, and the fourth edge 114 abuts against the third positioning member 323, so that the product 1 can be positioned in this way. It can be understood that in some embodiments, the number of the first positioning member 321, the second positioning member 322, and the third positioning member 323 can also be other numbers.

[0039] The fixing portion 33 includes a fixing plate 331, a first adsorption portion 332, and a second adsorption portion 333. The fixing plate 331 is disposed on the support base 31. Specifically, the fixing plate 331 is disposed on the top plate 312. The first adsorption portion 332 is disposed on the fixing plate 331 at a position corresponding to the middle of the product 1, and the first adsorption portion 332 is used to adsorb the middle of the product 1. The second adsorption portion 333 is disposed on the fixing plate 331 and is disposed around the first adsorption portion 332. By adsorbing the middle of the product 1 through the first adsorption portion 332 and adsorbing the edge of the product 1 through the second adsorption portion 333, the product 1 can be stably fixed on the fixing plate 331, and further the product 1 can be stably fixed on the support base 31.

[0040] such as Figure 5 , Figure 6 and Figure 7As shown, the first adsorption part 332 includes a convex part 3321, a groove 3322, an adsorption cavity 3323, a cover plate 3324, adsorption holes 3325, an air suction pipe 3326, a vacuum pumping device (not shown in the figure), a sealing ring installation groove 3327 and a sealing ring (not shown in the figure). The convex part 3321 protrudes upward from the upper side surface of the fixing plate 331, and the upper side surface of the convex part 3321 is a plane. The groove 3322 is recessed upward from the lower side surface of the fixing plate 331 at a position corresponding to the convex part 3321. The adsorption cavity 3323 is recessed upward from the bottom wall of the groove 3322. The cover plate 3324 is arranged in the groove 3322 and is adapted to the groove 3322. The cover plate 3324 is used to close the lower end of the adsorption cavity 3323. The adsorption holes 3325 are multiple. It can be understood that the number of the adsorption holes 3325 is not limited to multiple. For example, in some embodiments, the adsorption hole 3325 can also be one or two. The multiple adsorption holes 3325 are formed on the convex part 3321. One end of the adsorption hole 3325 communicates with the upper side surface of the fixing plate 331, and the other end of the adsorption hole 3325 communicates with the adsorption cavity 3323. The air suction pipe 3326 is formed on the cover plate 3324. One end of the air suction pipe 3326 communicates with the adsorption cavity 3323. The vacuum pumping device can be a centrifugal vacuum pump. The vacuum pumping device communicates with the other ends of all the adsorption holes 3325. Specifically, the vacuum pumping device is connected to the other end of the air suction pipe 3326. The vacuum pumping device communicates with the other ends of all the adsorption holes 3325 through the air suction pipe 3326 and the adsorption cavity 3323. The sealing ring installation groove 3327 is recessed downward from the upper side surface of the convex part 3321. The sealing ring installation groove 3327 surrounds the multiple adsorption holes 3325. The sealing ring is arranged in the sealing ring installation groove 3327. The upper side surface of the sealing ring protrudes from the upper side surface of the fixing plate 331. The first adsorption part 332 is used to adsorb the product 1 so that the product 1 compresses the sealing ring and makes the part of the product 1 inside the sealing ring fit with the part of the upper side surface of the fixing plate 331 inside the sealing ring. When the product 1 is placed on the first adsorption part 332, the product 1 is supported on the sealing ring. At this time, a closed space is formed among the product 1, the sealing ring and the upper side surface of the convex part 3321. Then, the vacuum pumping device is started, and the air in the closed space enters the vacuum pumping device successively through the adsorption holes 3325, the adsorption cavity 3323 and the air suction pipe 3326 and is discharged through the vacuum pumping device.During the vacuum pumping process, the product 1 gradually compresses the sealing ring and is supported on the upper side surface of the convex portion 3321, and finally the product 1 is tightly adsorbed on the convex portion 3321. The portion of the product 1 corresponding to the inner side of the sealing ring can be attached to the portion of the upper side surface of the convex portion 3321 located inside the sealing ring. It can be understood that the first adsorption portion 332 is not limited to the structure described above. For example, in some embodiments, the first adsorption portion 332 may also only include the convex portion 3321, the adsorption holes 3325, the vacuum pumping device, the sealing ring installation groove 3327, and the sealing ring. The air inlet of the vacuum pumping device is connected to each of the adsorption holes 3325 through a pipeline, and the closed space can also be evacuated.

[0041] The second adsorption part 333 is used to adsorb the product 1 so that the part of the product 1 corresponding to the outside of the sealing ring fits with the part of the upper side surface of the fixing plate 331 located outside the sealing ring. The second adsorption part 333 includes a plurality of convex rings 3331 and a plurality of suction cups 3332. The plurality of convex rings 3331 are arranged around the convex part 3321 in a surrounding manner. The upper side surface of the convex ring 3331 is flush with the upper side surface of the convex part 3321. The plurality of suction cups 3332 are respectively arranged in the plurality of convex rings 3331. The adsorption end of the suction cup 3332 protrudes upward from the upper end surface of the convex ring 3331. When the first adsorption part 332 adsorbs the product 1 on the convex part 3321, the edges of the product 1 are pressed downward, so that the part of the product 1 around the convex part 3321 is supported on the upper side surfaces of the respective convex rings 3331 and adsorbed by the suction cups 3332. At this time, the part of the product 1 corresponding to the outside of the sealing ring can fit with the part of the upper side surface of the convex part 3321 located outside the sealing ring. Under the combined adsorption and fixation action of the first adsorption part 332 and the second adsorption part 333 on the product 1, it can correct some warped and deformed products 1, so that the product 1 can maintain good flatness when adsorbed on the convex part 3321, and further improve the pressing and bonding accuracy of the mandrel. It can be understood that the second adsorption part 333 is not limited to the above-described structure. For example, in some embodiments, the second adsorption part 333 may further include a plurality of convex blocks formed by protruding upward from the upper side surface of the fixing plate 331 and having an upper side surface flush with the upper side surface of the convex part 3321, an annular groove formed by recessing downward from the upper side surface of the convex block, a rubber ring arranged in the annular groove and having an upper side surface protruding from the upper side surface of the convex block, and a vacuum pump communicated with the space surrounded by the rubber ring on the convex block. The plurality of convex blocks are arranged around the convex part 3321. When adsorbing the product 1, the edge of the product 1 is pressed on the upper side surface of the rubber ring, and the vacuum pump is started. The vacuum pump sucks the space surrounded by the rubber ring on the convex block, and under the action of atmospheric pressure, the rubber ring can be compressed, and the lower side surface of the product 1 can be abutted against the upper side surface of the convex block. At this time, the part of the product 1 corresponding to the outside of the sealing ring can also fit with the part of the upper side surface of the convex part 3321 located outside the sealing ring.

[0042] Such as Figure 4As shown, the pushing mechanism 34 includes a third linear slide module 341, a first slide rail 342, and a first slide groove 343. One end of the third linear slide module 341 faces the opening 231, and the other end of the third linear slide module 341 faces away from the opening 231. The third linear slide module 341 and the first slide rail 342 are both arranged on the seat plate 22. The bottom plate 311 is arranged on the third linear slide module 341, and the first slide groove 343 is arranged on the bottom plate 311. The first slide groove 343 is slidably engaged with the first slide rail 342. With this structure, the pushing mechanism 34 can drive the support seat 31 to move towards or away from the opening 231. The first slide rail 342 guides the first slide groove 343, and thus can guide the movement of the support seat 31, making the movement of the support seat 31 more stable when moving towards or away from the opening 231.

[0043] As Figure 8 shown, the pressing drive mechanism 41 includes five second drive mechanisms 411. It can be understood that in some embodiments, the pressing drive mechanism 41 can also be three or more other quantities. The second drive mechanism can be a cylinder, a hydraulic cylinder, or a push rod motor. Each of the second drive mechanisms 411 is arranged on the frame 2. Specifically, the five second drive mechanisms 411 are all arranged on the lifting drive mechanism 6. The lifting drive mechanism 6 is arranged on the translation drive mechanism 7. The translation drive mechanism 7 is arranged on the auxiliary support frame 24. That is, each of the second drive mechanisms 411 is arranged on the frame 2 through the lifting drive mechanism 6 and the translation drive mechanism 7. Each of the second drive mechanisms 411 is arranged in sequence along the length direction parallel to the core shaft installation groove 121. It can be understood that in some embodiments, each of the second drive mechanisms 411 can also be directly installed on the auxiliary support frame 24.

[0044] The pressing part 42 includes five pressing claws 421. It can be understood that in some embodiments, the number of the pressing claws 421 can also be three or more other numbers. The plurality of pressing claws 421 respectively correspond to the five second driving mechanisms 411 one by one. The pressing claws 421 are arranged on the output shafts of the corresponding second driving mechanisms 411, that is, pressing claws 421 are arranged on the output shafts of the respective second driving mechanisms 411. The respective second driving mechanisms 411 are configured to respectively drive the respective pressing claws 421 to move towards the mandrel mounting groove 121 on the product 1 mounted and positioned on the product positioning mechanism 3 and press the mandrel into the mandrel mounting groove 121. The respective second driving mechanisms 411 respectively drive the respective pressing claws 421 to press the mandrel into the mandrel mounting groove 121, so as to form a plurality of independent pressing points on the mandrel, making the force on the mandrel more uniform and improving the assembly accuracy of the mandrel in the mandrel mounting groove 121. When changing the driving stroke of the respective second driving mechanisms 411, mandrels with different thicknesses within a certain range can be pressed.

[0045] The pressing claw 421 includes a pressing claw body 4211 and a pressing opening 4212 that is recessed inward from the side surface of the pressing claw body 4211 facing the mandrel mounting groove 121 and is adapted to the mandrel. When pressing the mandrel, the pressing opening 4212 is stuck on the mandrel to restrict the mandrel and prevent the mandrel from displacing in the up-and-down direction.

[0046] Such as Figure 9As shown, the pressing jaw 421 is not limited to the structure described above. For example, in some embodiments, the pressing jaw 421 includes a pressing jaw body 4211 and an elastic portion 4213 disposed on one side of the pressing jaw body 4211 facing the mandrel mounting groove and capable of elastic deformation. The elastic portion is used to abut against the mandrel to press the mandrel in the mandrel mounting groove 121. On the side of the elastic portion 4213 facing the mandrel mounting groove 121, a pressing opening 4212 for clamping the mandrel is formed by inward depression when the elastic portion 4213 abuts against the mandrel. The elastic portion 4213 may be a soft elastic rubber block disposed on one side of the pressing jaw body 4211 facing the mandrel mounting groove 121. The pressing opening 4212 is formed on the side of the soft elastic rubber block facing the mandrel mounting groove 121. The elastic rubber block has the ability of elastic deformation. When pressing a mandrel with a thickness larger than the size of the pressing opening 4212, the mandrel can expand the pressing opening 4212, so that the pressing opening 4212 can clamp mandrels of different sizes within a certain range, and the applicable range is wide. The elastic rubber block has the ability of elastic deformation, which can make the pressing opening 4212 more easily fit the surface of the mandrel with an irregular shape. The elastic rubber block can also be compressed, and without changing the driving stroke of each of the second driving mechanisms 411, the pressing jaw 421 can also press mandrels of different thicknesses within a certain range, and the adaptability is strong. Of course, the elastic portion can also be made of a material with elastic deformation ability.

[0047] As Figure 3 As shown, the heating mechanism 5 is disposed on the support base 31. The heating mechanism 5 is used to heat the side plate 12. By heating the side plate 12 through the heating mechanism 5, the temperature of the side plate 12 can be increased. After pressing the mandrel with glue applied thereon into the mandrel mounting groove 121, the higher temperature can make the glue cure quickly, and the bonding efficiency between the mandrel and the product 1 can be improved.

[0048] As Figure 10As shown, the heating mechanism 5 includes a heating part 51 and a first driving mechanism 52. The heating part 51 is used to abut against the side of the side plate 12 facing away from the mandrel mounting groove 121, and the heating part 51 is used to heat the side plate 12. The first driving mechanism 52 can be a cylinder, a hydraulic cylinder or a push rod motor. The first driving mechanism 52 is arranged on the supporting part. Specifically, the first driving mechanism 52 is arranged on the lower side of the top plate 312. The first driving mechanism 52 is used to drive the heating part 51 to move towards the side plate 12 and abut against the side plate 12, and the first driving mechanism 52 is also used to drive the heating part 51 to move away from the side plate 12 so that the heating part 51 disengages from the side plate 12. Before the clamping jaw 421 clamps the mandrel, the first driving mechanism 52 drives the heating part 51 to move towards the side plate 12 and abut against the side plate 12. The heating part 51 has the function of heating the side plate 12, and at the same time, it also has the function of supporting the side of the side plate 12 facing away from the mandrel mounting groove 121, which can quickly cure the glue on the mandrel, quickly bond the mandrel in the mandrel mounting groove 121, and prevent the side plate 12 from being damaged when the clamping jaw 421 clamps the mandrel. Before the product 1 needs to be taken out from the support base 31, the first driving mechanism 52 drives the heating part 51 to move away from the side plate 12 so that the heating part 51 disengages from the side plate 12, preventing the heating part 51 from scalding workers and improving safety.

[0049] The heating part 51 includes a connecting plate 511, a second slide rail 512, a second slide groove 513, a heat conducting block 514 and a heating rod (not shown in the figure). The connecting plate 511 is connected to the output shaft of the first driving mechanism 52. The second slide rail 512 is arranged on the lower side of the top plate 312. The second slide groove 513 is arranged on the upper side of the connecting plate 511. The second slide groove 513 is slidably engaged with the second slide rail 512. The heat conducting block 514 is arranged on the connecting plate 511 at a position corresponding to the side plate 12. The heating rod is arranged on the heat conducting block 514 and is used to heat the heat conducting block 514. By driving the connecting plate 511 to move through the first driving mechanism 52, and then driving the heat conducting block 514 to move towards the side plate 12 until the heat conducting block 514 abuts against the side plate 12, the side plate 12 can be heated and supported. Under the guiding action of the cooperation between the second slide groove 513 and the second slide rail 512, the heat conducting block 514 moves towards the side plate 12 more stably.

[0050] As Figure 3As shown, the lifting drive mechanism 6 is used to drive the pressing drive mechanism 41 to lift. Before positioning and fixing the product 1 on the support base 31, the lifting drive mechanism drives the pressing drive mechanism 41 to rise, that is, the lifting drive mechanism 6 drives the second drive mechanism 411 to rise, and the pressing part 42 rises with the pressing drive mechanism 41, that is, the clamping jaw 421 rises with the second drive mechanism 411, so that the second drive mechanism 411 and the clamping jaw 421 will not block the positioning and fixing of the product 1 on the support base 31, making it more convenient to position and fix the product 1 on the support base 31. Before pressing the mandrel into the mandrel mounting groove 121, the lifting drive mechanism 6 drives the second drive mechanism 411 and the clamping jaw 421 to descend, so that the height of the clamping jaw 421 descends to face the mandrel mounting groove 121 directly.

[0051] The lifting drive mechanism 6 is a second linear slide module vertically arranged on the translation drive mechanism 7, and the second linear slide module is driven by a servo motor. The lifting drive mechanism 6 is a second linear slide module driven by a servo motor. The servo motor has high movement accuracy and can make the clamping jaw 421 accurately align with the mandrel mounting groove 121 after descending. It can be understood that in some embodiments, the lifting rod drive can also be a cylinder.

[0052] As Figure 3 shown, the translation drive mechanism 7 is used to drive the lifting drive mechanism 6 to move along the length direction parallel to the mandrel mounting groove 121, and thus can drive the second drive mechanism 411 and the clamping jaw 421 to move along the length direction parallel to the mandrel mounting groove 121, facilitating the horizontal alignment of the clamping jaw 421 with the mandrel mounting groove 121.

[0053] The translation drive mechanism 7 is a first linear slide module arranged on the frame 2 and arranged along the length direction parallel to the mandrel mounting groove 121. Specifically, the first linear slide module is arranged on the auxiliary support frame 24, and the first linear slide module is driven by a servo motor. The servo motor has high movement accuracy and can make the clamping jaw 421 accurately align with the mandrel mounting groove 121 in the horizontal direction. It can be understood that in some embodiments, the translation drive mechanism 7 can also be a cylinder.

[0054] The above embodiments only represent the preferred implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
