DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 6As shown, the present invention provides: a pen cap and bushing automatic assembly equipment, which is used to assemble a pen cap body 100 and a bushing body 200 together to form a pen, including a pen cap assembly mechanism 1, a bushing assembly mechanism 2, a main body 5 and a synchronization component 6. The pen cap assembly mechanism 1 can move up and down on the main body 5, and the bushing assembly mechanism 2 can move up and down on the main body 5. The pen cap assembly mechanism 1 is provided with a fixing mechanism 3 for fixing the pen cap body 100, and the bushing assembly mechanism 2 is also provided with a fixing mechanism 3 for fixing the bushing body 200. The fixing mechanism 3 can adopt a pneumatic or electromagnetic clamping method, which can firmly fix the pen cap body 100 or the bushing body 200 to prevent shaking or falling off during the assembly process. The pen cap assembly mechanism 1 is provided with a driving mechanism 7 that can make the fixing mechanism 3 rotate around its own axis. The driving mechanism 7 can be composed of a motor and a reducer, and can drive the fixing mechanism 3 (and the pen cap body 100) to rotate around its axis at a certain angle. The fixing mechanism 3 in the bushing assembly mechanism 2 cannot rotate, and a position detection component 4 for detecting whether the pen cover body 100 and the bushing body 200 are aligned is also arranged between the pen cover assembly mechanism 1 and the bushing assembly mechanism 2. A synchronization component 6 for synchronous movement of the pen cover assembly mechanism 1 and the bushing assembly mechanism 2 is also installed on the main body 5. When the pen cover body 100 and the bushing body 200 are respectively placed in the pen cover assembly mechanism 1 and the bushing assembly mechanism 2, the synchronization component 6 makes the pen cover assembly mechanism 1 and the bushing assembly mechanism 2 move relative to each other, and the pen cover body 100 is inserted into the bushing body 200. The position detection component 4 can monitor the relative position of the pen cover body 100 and the bushing body 200 in real time to ensure that the two are in a precise alignment state before assembly. Once a position deviation is detected, the position detection component 4 will immediately send a signal to the control system, and the control system will adjust the position of the pen cover assembly mechanism 1 and / or the bushing assembly mechanism 2 until the predetermined alignment standard is reached.

[0033] The pen cover body 100 and the bushing body 200 are placed on the fixing mechanism 3 of the pen cover assembly mechanism 1 and the bushing assembly mechanism 2 respectively through an automatic loading mechanism or manual loading, the position detection component 4 is started, and the alignment detection of the pen cover body 100 and the bushing body 200 is performed, the synchronization component 6 is started, and the pen cover assembly mechanism 1 and the bushing assembly mechanism 2 are driven to move relative to each other until the pen cover body 100 is accurately inserted into the bushing body 200, and the fixing mechanism 3 of the pen cover assembly mechanism 1 is rotated through the driving mechanism 7, and then the pen cover body 100 is screwed into the bushing body 200 to achieve quick assembly.

[0034] refer to Figure 7As shown, the pen cover assembly mechanism 1 includes a rotatable upper rotating disk 13, and a pen cover limiting ring 14 is arranged at the position of the fixing mechanism 3 in the upper rotating disk 13, and a limiting hole is also arranged at the center position of the pen cover limiting ring 14, and the pen cover body 100 is inserted into the limiting hole, so that the pen cover limiting ring 14 will abut against the step on the pen cover body 100 close to the pen tip, and the bushing assembly mechanism 2 includes a rotatable lower rotating disk 23, and a bushing limiting ring 24 is arranged at the position of the fixing mechanism 3 of the lower rotating disk 23, and the bushing limiting ring 24 abuts against one end of the bushing body 200.

[0035] The limiting hole at the center of the pen cap limiting ring 14 matches the shape and size of the pen cap body 100 to ensure that the pen cap can be inserted accurately. At the same time, the pen cap limiting ring 14 will abut against the step near the pen tip on the pen cap body 100 to keep the length of the pen cap body 100 consistent. The bushing limiting ring 24 is used to keep the length of each bushing body 200 consistent.

[0036] refer to Figure 8 and Fig.10 As shown, the fixing mechanism 3 includes a moving member 34 that can move back and forth. As a key component for clamping the pen cap or bushing, the moving member 34 can move back and forth along a preset track. This design allows the clamping force and position to be adjusted according to the size and shape of the pen cap or bushing, ensuring the stability and accuracy of the clamping. A clamping plate 342 is provided on the inner side of the moving member 34, and the clamping plate 342 is made of a flexible material. A pressure sensor for detecting the clamping force is also installed inside the clamping plate 342, and the clamping plate 342 is made of a flexible material. The use of flexible materials not only ensures the softness and adaptability during clamping, reduces the damage to the pen cap or bushing, but also improves the reliability of clamping. The pressure sensor installed inside the clamping plate 342 can detect the clamping force in real time, ensuring that the clamping force is neither too large nor too small, thereby protecting the pen cap or bushing from damage. When the movable member 34 moves, the clamping plate 342 is clamped on the outside of the pen cover body 100 or the sleeve body 200. A sliding groove 341 is provided on the side of the movable member 34 away from the clamping plate 342. The fixing mechanism 3 also includes a fixing member 32. A limiting column 33 is provided on the fixing member 32. The limiting column 33 is inserted into the sliding groove 341. When the movable member 34 moves, the limiting column 33 slides in the sliding groove 341. A movable rod 36 that can move up and down is installed at the center position of the fixing member 32. A plurality of connecting rods 35 are movably arranged on the outside of the movable rod 36 through an axial movement. One end of each connecting rod 35 is movably connected to its corresponding movable member 34. A telescopic driving member 31 is also installed on the top of the fixing member 32. The output end of the telescopic driving member 31 is fixedly connected to one end of the movable rod 36. When the telescopic driving member 31 moves the movable rod 36, the movable rod 36 causes the connecting rod 35 to drive the movable member 34 to move back and forth.

[0037] When the pen cap body 100 or the bushing body 200 is placed at the predetermined position of the fixing mechanism 3, the telescopic driving member 31 is started to drive the moving rod 36 to move. The moving rod 36 drives the moving member 34 to move inward through the connecting rod 35, and the limiting column 33 slides in the slide groove 341, so that the clamping plate 342 is clamped on the outside of the pen cap or bushing to ensure that the moving member 34 moves along the predetermined trajectory. At the same time, the pressure sensor inside the clamping plate 342 monitors the clamping force in real time to ensure that the clamping force is moderate. When the clamping force reaches the preset value, the telescopic driving member 31 stops working, and the fixing mechanism 3 firmly fixes the pen cap or bushing in the predetermined position, preparing for subsequent assembly operations. After the assembly is completed, the telescopic driving member 31 works in reverse to move the moving member 34 outward and release the pen cap body 100 or the bushing body 200.

[0038] refer to Figure 8 and Fig. 9 As shown, the driving mechanism 7 includes a driven gear 73, which is fixed on the fixing member 32 in the fixing mechanism 3. The driving mechanism 7 also includes a fourth rotating driving member 72. The output end of the fourth rotating driving member 72 is connected to the driving gear 71. The driving gear 71 and the driven gear 73 are meshed with each other. When the fourth rotating driving member 72 is started, the driving gear 71 is driven to rotate and then the driven gear 73 is rotated. The driven gear 73 drives the fixing mechanism 3 to make one end of the pen cover body 100 screwed into the sleeve body 200.

[0039] When the pen cap body 100 and the bushing body 200 have been moved to relative positions by the synchronization assembly 6, and the pen cap body 100 is firmly clamped by the fixing mechanism 3, the driving mechanism 7 starts to work. The fourth rotary drive member 72 is started to drive the driving gear 71 to rotate. Since the driving gear 71 and the driven gear 73 are meshed with each other, the driven gear 73 will also rotate, and drive the fixing mechanism 3 and the clamped pen cap body 100 to rotate together. As the pen cap body 100 rotates, one end of it will gradually screw into the bushing body 200 until it reaches a predetermined assembly depth. During the whole process.

[0040] The pen cover assembly mechanism 1 includes an upper sliding plate 12, a first rotary drive member 11 is fixed to the top of the upper sliding plate 12, the output end of the first rotary drive member 11 passes through the upper sliding plate 12 and is fixed to the top of the upper rotating disk 13, and when the first rotary drive member 11 is started, the upper rotating disk 13 is driven to rotate. The first rotary drive member 11 is usually a high-precision, high-torque motor or servo motor, and its output end passes through the upper sliding plate 12 and is fixedly connected to the top of the upper rotating disk 13. When the first rotary drive member 11 is started, it drives the upper rotating disk 13 to rotate around its central axis, thereby driving the pen cover body 100 or other related components fixed on the upper rotating disk 13 to rotate.

[0041] The bushing assembly mechanism 2 includes a lower sliding plate 22, and a second rotating driving member 21 is fixed to the bottom of the lower sliding plate 22 by bolts. The output end of the second rotating driving member 21 passes through the lower sliding plate 22 and is fixedly connected to the bottom of the lower rotating disk 23. When the second rotating driving member 21 is started, the lower rotating disk 23 is driven to rotate. The second rotating driving member 21 is a high-precision, high-torque motor or servo motor. Its output end passes through the lower sliding plate 22 and is fixedly connected to the bottom of the lower rotating disk 23. When the second rotating driving member 21 is started, it drives the lower rotating disk 23 to rotate, thereby driving the bushing body 200 or other related components fixed on the lower rotating disk 23 to rotate.

[0042] The position detection component 4 includes a light emitting module 41 and a photoelectric sensor 42. The light emitting module 41 is evenly installed at the bottom of the upper rotating disk 13 near the fixing mechanism 3, and the photoelectric sensor 42 is evenly installed at the top of the lower rotating disk 23 near the fixing mechanism 3. The light emitting module 41 emits a laser which is received by the photoelectric sensor 42, converts the optical signal into an electrical signal, and sends the position information to the control terminal to control the alignment of the pen cover body 100 and the sleeve body 200.

[0043] The light emitting module 41 emits light which is received by the photoelectric sensor 42. The photoelectric sensor 42 converts the light signal into an electrical signal and transmits the electrical signal to the control terminal, thereby detecting the positions of the upper rotating disk 13 and the lower rotating disk 23 in real time, thereby preventing the pen cover body 100 and the sleeve body 200 from being misaligned and causing the pen cover body 100 and the sleeve body 200 to be crushed.

[0044] The synchronization component 6 includes a limit rod 61, which is used to guide the pen sleeve assembly mechanism 1 and the bushing assembly mechanism 2. The upper sliding plate 12 in the pen sleeve assembly mechanism 1 is slidably set on the limit rod 61, and the lower sliding plate 22 in the bushing assembly mechanism 2 is also slidably set on the limit rod 61. A second transmission rod 63 is also rotatably set between the upper sliding plate 12 and the lower sliding plate 22, and a first transmission rod 62 is rotatably set at one end of the second transmission rod 63. The synchronization component 6 also includes a worm gear 64, which is set on the second transmission rod 63 through an axis. The synchronization component 6 also includes a worm 65 and a third rotation driving member 66. The output end of the third rotation driving member 66 is interconnected with one end of the worm 65, and the worm gear 64 and the worm 65 are meshed with each other.

[0045] During the assembly process, the control terminal will issue a command to start the third rotary drive member 66, and the third rotary drive member 66 drives the worm 65 to rotate. The rotational motion of the worm 65 is transmitted to the worm wheel 64 to rotate the second transmission rod 63, and the rotational motion of the second transmission rod 63 is converted into the linear sliding motion of the upper sliding plate 12 and the lower sliding plate 22 through the first transmission rod 62. Since the upper sliding plate 12 and the lower sliding plate 22 are both slidably arranged on the limit rod 61 and are connected by the transmission rod, they can maintain synchronous movement, so that the pen cover body 100 is inserted into the bushing body 200.

[0046] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
