Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and more specifically to a grinding and shaping mechanism for soft-flanging of terminal blocks. Background Technology

[0002] A voice recorder is a product combining electronic devices and educational tools. Designed for business use and to record meeting content, a voice recorder includes a microphone, memory card, control chip, lithium battery, indicator light, and terminal board. (See also...) Figure 12 The terminal board is L-shaped and lightweight. After being soldered with components such as control chips, memory cards and indicator lights, it needs to be folded multiple times online. The terminal board undergoes multiple folding and rolling actions through automated equipment. Since the terminal board is made of copper, which is relatively soft, although the required force for folding and rolling is not high, it still leads to a decrease in the forming stability after folding and rolling.

[0003] For example Figure 12 The upper and lower rolled edges form the coiled section. The finished product requires a gap of 0.3-0.5mm between the upper and lower rolled edges after coiling, and they must remain parallel to each other to fill the necessary PI film or gasket material, ensuring that less space is occupied within the limited space of the recorder. This poses a great challenge to the automatic folding process of terminal boards with soft materials. Therefore, it is necessary to design an automatic edge-rolling and folding mechanism that can keep the upper and lower rolled edges within the qualified dimensional accuracy range after coiling, so as to improve the production efficiency and quality of the terminal board folding and flanging process. Summary of the Invention

[0004] The purpose of this invention is to maintain the upper and lower rolled edges of the terminal board within the acceptable dimensional accuracy range after rolling, ensuring the quality of the rolled structure and improving the production efficiency and quality of the terminal board folding and flanging process. We have designed and proposed a grinding and heat-setting mechanism for soft flanging of terminal boards. An automatic flipping and bending assembly is used to gradually bend the upper rolled edge of the terminal board close to the lower rolled edge. A pressure-holding and setting assembly, in conjunction with a rotating rolling rod, generates heat through friction on the unset rolled part and cools and sets it under air cooling conditions, achieving the required gap dimensional accuracy between the upper and lower rolled edges of the finished product, thereby improving the production efficiency and quality of the terminal board folding and flanging process.

[0005] The technical solution adopted to solve the above problems is:

[0006] A heat-setting and shaping mechanism for soft-flanging of terminal boards includes a material carrier, an automatic flipping and bending assembly, a pressure-holding and shaping assembly, an automatic winding assembly, and an auxiliary pressing assembly.

[0007] Positioning platforms are symmetrically placed on both sides of the loading platform. The terminal plates to be wound are placed inside the positioning platforms. The lower end of the loading platform is pushed by a lifting cylinder to feed the material to the automatic flipping and bending assembly.

[0008] The automatic flipping and bending assembly includes a flipping motor, a driving pulley, a transmission belt, a driven pulley, a flipping shaft, bearing seats, and bending blocks. The main shaft of the flipping motor is connected to the driving pulley, which transmits power to the driven pulley via the transmission belt. The driven pulley is fixedly connected to the flipping shaft via a sleeve, driving the flipping shaft to rotate. Both ends of the flipping shaft are fitted with bearing seats for positioning. Bending blocks are provided at both ends of the flipping shaft, and each bending block has a bending portion. The bending portion performs a rotational bending action on the upper rolled edge of the terminal plate.

[0009] The pressure-holding and shaping assembly is located behind the loading platform and includes a pressure-holding cylinder, a limiting slide, a push block, a pressure-holding block, and a pin. The limiting slide houses a linearly sliding push block. The tail of the push block is connected to the push rod of the pressure-holding cylinder, and the front of the push block is connected to a pin. The pin is tangentially engaged with an obliquely shaped hole in the center of the pressure block. The tail of the pressure block is movably connected to the limiting slide via a hinge shaft. Under the linear push of the pin shaft, the pressure block rotates around the hinge shaft and presses down on the already folded upper edge of the loading platform, maintaining this pressing posture.

[0010] The automatic winding assembly is positioned on the flip shaft and includes a winding bar, a bearing housing, a winding motor, and a position adjustment component. The front end of the winding bar has a friction bar with a diameter equal to the inner hole of the winding section. A driven pulley is located in the middle of the winding bar, and the rotational power of the winding motor is driven by a transmission belt and a driving pulley. The bearing housing linearly positions the winding bar, and the bearing housing and winding motor are fixed to an adjustment frame. The adjustment frame's position is adjusted in three coordinate directions by the position adjustment component. The friction bar is inserted directly into the inner hole of the winding section and rotates at high speed under the drive of the winding motor. This causes the friction bar to rub against the inner wall of the winding section with a small sliding friction force, generating heat evenly and slowly, gradually softening the winding section. The friction bar then stops rotating and retracts, allowing the winding section to be air-cooled.

[0011] The auxiliary pressing component is located above the loading platform and includes a pressing cylinder, a slider rail assembly and a pressure holding rod fixed on the support frame. The pressure holding rod is driven to lift and lower by the pressing cylinder and provides auxiliary pressing and posture maintenance for the upper rolled edge during the turning and bending process.

[0012] Furthermore, the bending portion is provided with a silicone pad that fits the upper rolled edge of the terminal plate.

[0013] Furthermore, the position adjustment assembly includes a lateral adjustment cylinder, a lateral slider rail assembly, a longitudinal adjustment bolt, a longitudinal slider rail assembly, a vertical adjustment cylinder, a vertical slider rail assembly, a lateral sliding plate, a longitudinal sliding plate, and an adjustment frame.

[0014] Furthermore, a shaping block is fixedly connected to the front end of the pressure-holding block, the shaping block is pressed above the coiling part, and an anti-wear block is filled at the lower end of the shaping block.

[0015] Furthermore, an arc-shaped curved surface is provided at the position where the lower end of the shaping block fits against the upper rolled edge.

[0016] The beneficial effects of implementing this invention are:

[0017] This heat-setting and shaping mechanism for soft edge folding of terminal boards utilizes an automatic flipping and bending assembly to flip and fold the upper rolled edge of the terminal board, achieving the initial folding action. Then, a coiling rod, in conjunction with a pressure-holding and shaping assembly, presses and positions the rolled portion according to the standard dimensional accuracy of the product. The rotating friction of the inner wall of the inner hole of the rolled portion generates heat from the friction, and then cools and shapes it under air cooling conditions, effectively preventing the upper rolled edge from springing back. This fully meets the 0.3-0.5mm gap size requirement of qualified products, improving the production efficiency and pass rate of the terminal board folding and flanging process.

Detailed Implementation

[0031] The technical solutions in the embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings provided.

[0032] Example:

[0033] Please see Figure 1-12 This embodiment proposes a grinding and shaping mechanism for soft-flanging of terminal plate 17, including a material carrier 2, two sets of automatic flipping and bending components 5 arranged symmetrically on the left and right, a pressure holding and shaping component, an automatic winding component 1, and an auxiliary pressing component 4. Positioning platforms 16 are symmetrically placed on both sides of the material carrier 2, and the terminal plate 17 to be wound is placed in the positioning platform 16. The lower end of the material carrier 2 is pushed and fed to the automatic flipping and bending component 5 by a lifting cylinder 3.

[0034] See Figure 4 , Figure 5 and Figure 6The automatic flipping and bending assembly 5 includes a flipping motor 6, a driving pulley 19, a transmission belt 20, a driven pulley, a flipping shaft 12, a bearing seat 7, and bending blocks 13. The main shaft of the flipping motor 6 is connected to the driving pulley 19. The driving pulley 19 transmits power to the driven pulley through the transmission belt 20. The driven pulley is fixedly connected to the flipping shaft 12 through a sleeve, driving the flipping shaft 12 to rotate. Both ends of the flipping shaft 12 are positioned and sleeved with the bearing seat 7. Bending blocks 13 are provided at both ends of the flipping shaft 12. The bending blocks 13 are provided with bending parts 21. The bending parts 21 perform a rotational bending action on the upper rolled edge 30 of the terminal plate 17.

[0035] See Figure 6 , Figure 7 , Figure 9 and Figure 10 The pressure-holding and shaping assembly is located behind the loading platform 2 and includes a pressure-holding cylinder 24, a limiting slide 23, a pusher 27, a pressure-holding block 22, and a pin. The limiting slide 23 is fitted with a linearly sliding pusher 27. The tail of the pusher 27 is connected to the top rod of the pressure-holding cylinder 24, and the front end of the pusher 27 is connected to a pin. The pin is tangentially fitted with an obliquely shaped hole in the middle of the pressure-holding block 22. The tail of the pressure-holding block 22 is movably connected to the limiting slide 23 via a hinge shaft. Under the linear push of the pin shaft, the pressure-holding block 22 rotates around the hinge shaft and presses down on the upper rolled edge 30 on the loading platform 2, which has already been flipped and folded, and maintains the pressing posture. The automatic winding assembly 1 performs a friction shaping process to prevent reverse rolling deformation on the winding part 29.

[0036] See Figure 3 , Figure 6 and Figure 11 The automatic winding assembly 1 is positioned on the flipping shaft 12 and includes a winding rod 15, a bearing seat 7, a winding motor 10, and a position adjustment assembly. The front end of the winding rod 15 is provided with a friction rod 34 with a diameter equal to that of the inner hole of the winding part 29. A driven pulley is provided in the middle of the winding rod 15, and the rotational power of the winding motor 10 is activated by the transmission belt 20 and the driving pulley 19. The bearing seat 7 linearly positions the winding rod 15. The bearing seat 7 and the winding motor 10 are fixedly connected to the adjustment frame. The position of the adjustment frame is adjusted in three coordinate directions by the position adjustment assembly. The friction rod 34 is inserted into the inner hole of the winding part 29 and rotates at high speed under the drive of the winding motor 10. The friction rod 34 rubs against the inner wall of the winding part 29 with a small sliding friction force, and heat is generated evenly and slowly. The winding part 29 is gradually softened. The friction rod 34 stops rotating and withdraws, and the winding part 29 is air-cooled. The winding part 29 is shaped by friction heating and cooling shrinkage.

[0037] See Figure 3The auxiliary pressing component 4 is located above the material platform 2 and includes a pressing cylinder, a slider rail assembly and a pressure holding rod 8 fixed on the support frame. The pressure holding rod 8 is driven by the pressing cylinder to lift and lower, and performs auxiliary pressing and posture holding on the upper rolled edge 30 during the turning and bending process, so that the rolled part 29 maintains the standard dimensional accuracy and posture during the cooling and shrinking process.

[0038] Further implementation plans are as follows, see [link / reference] Figure 11 The bending part 21 is provided with a silicone pad 33 that fits the upper rolled edge 30 of the terminal plate 17, and uses static friction to stably bend and flip.

[0039] A further embodiment is that the position adjustment assembly includes a lateral adjustment cylinder 11, a lateral slider rail assembly, a longitudinal adjustment bolt 25, a longitudinal slider rail assembly, a vertical adjustment cylinder 9, a vertical slider rail assembly, a lateral sliding plate, a longitudinal sliding plate 26, and an adjustment frame.

[0040] Further implementation plans are as follows, see [link / reference] Figure 9 The front end of the pressure holding block 22 is fixedly connected to the shaping block 14, which is pressed above the coiling part 29, and the lower end of the shaping block 14 is filled with an anti-wear block 28.

[0041] Further implementation plans are as follows, see [link / reference] Figure 9 The lower end of the shaping block 14 is provided with an arc-shaped curved surface 32 at the position where it fits against the upper rolled edge 30. This surface keeps the shape of the upper rolled edge 30 unchanged during the rotation of the friction rod 34 and plays a shaping role during the cooling process of the rolled portion 29.

Within the scope of knowledge possessed by those skilled in the art, various changes, modifications, substitutions and variations can be made without departing from the spirit of the present invention.
