Description

Technical Field

[0001] The invention belongs to the technical field of hemming machine equipment, and particularly relates to a semi-automatic hemming device. Background Art

[0002] The hemming machine is a device used to stack copper sheets, aluminum sheets, and wooden pads according to the process and hem them on all four sides.

[0003] In the prior art, semi-automatic hemming machines often use manual placement of aluminum sheets, wooden pads, and copper sheets. When placing aluminum sheets manually, it is easy to cause a large deviation between the placement position and the placement position specified by the operation, and it takes a lot of time to accurately place the aluminum sheets. When manually stacking wooden pads and copper sheets, the holes of the pins on the wooden pads and copper sheets need to be aligned, so that the upper pins will not easily cause the copper sheets or wooden pads to crack. It takes a lot of time to perform two types of alignments, one of which is the alignment between the holes of the wooden pads and the copper sheets, and the other is that the holes of the wooden pads and the copper sheets need to be aligned with the positions of the upper pins to ensure accurate pinning. The above-mentioned manual placement of materials is cumbersome and complicated to operate, consumes energy and time, and greatly reduces the efficiency of hemming operations. Summary of the Invention

[0004] The embodiment of the present application provides a semi-automatic edging device, which solves the problem of low operating efficiency caused by manual placement of plate materials through the arrangement of an upper pin component and an upper aluminum sheet component, achieves improved precise alignment of manual stacking, saves a lot of alignment time, enables rapid alignment and placement, effectively improves the efficiency of edging operations, and is quick and convenient to operate.

[0005] The technical solutions provided by the embodiments of this application are:

The lifting mechanism is a lifting mechanism, and a lifting mechanism is a lifting mechanism. The lifting mechanism is a lifting mechanism, and a lifting mechanism is a lifting mechanism.

The lifting mechanism is a lifting mechanism, and a lifting mechanism is a lifting mechanism. The lifting mechanism is a lifting mechanism, and a lifting mechanism is a lifting mechanism.

[0007] In the present invention, the process of stacking the wooden pads and copper sheets in sequence is as follows: before placing the wooden pads, the lifting body is activated, the positioning pin is raised, and the positioning pin passes through the guide hole to expose the support plate. The hole of the wooden pad passes through the positioning pin to position the wooden pad; then the hole of the copper sheet passes through the positioning pin, and the copper sheet is accurately stacked on top of the wooden pad. After the alignment is completed, the upper pinning machine presses the copper sheet downward, and the positioning pin is now located at the upper pin opening. The lifting body moves downward, driving the positioning pin to move downward to below the guide hole. The upper pinning machine then passes the pin through the upper pin opening and drives it into the holes of the wooden pads and copper sheet, thereby completing the pinning operation. Through this setting, the time spent on alignment is greatly reduced, alignment is rapid, and the efficiency of stacking the wooden pads and copper sheets is effectively improved. The operation is convenient and quick, and the difficulty of stacking is reduced. By providing a guide hole, it can be used for the precise upward movement of the positioning pin, serving as a guide operation; during the pinning operation, the impact force of the pin hitting the wooden pads and copper sheet can be effectively buffered, ensuring the quality of the pinning. By arranging the upper pin opening, the guide hole and the positioning pin on the same vertical line, the alignment and the position consistency of the upper pin are ensured, thereby ensuring the quality of the upper pin.

[0008] The manual sheet placement process is as follows: adjust the first adjustment body to its widest range, i.e., the longest straight-line distance between the first and second limiting slots. Place the sheet on the support plate next to the first limiting post. Then, rotate the first adjustment body to gradually narrow the range until the front and back edges of the sheet are positioned by the first adjustment body. This completes the sheet placement process. This method effectively reduces sheet placement deviation and improves accuracy. It is simple and quick to operate, significantly reducing the time required for precise sheet placement and effectively improving sheet placement efficiency, thereby shortening the hemming process and increasing hemming production efficiency. Each action can be controlled by an existing PLC program.

[0009] Furthermore, the storage mechanism also includes a second adjusting body at the lower end of the other side of the supporting plate; the supporting plate is provided with a third limiting groove corresponding to the second adjusting body; the second adjusting body moves in the third limiting groove.

[0010] The second adjusting body is used to limit the other side of the aluminum sheet relative to the first limiting post. With this arrangement, after the first adjusting body positions the aluminum sheet front and back, the second adjusting body also limits the other side of the aluminum sheet, thereby limiting all four sides of the aluminum sheet. This further improves the accuracy of aluminum sheet placement, effectively prevents deviation, and effectively ensures the accuracy and quality of subsequent stacking operations.

[0011] Among them, the first limiting column is symmetrically arranged with respect to the third limiting groove. Through this arrangement, the tilting phenomenon caused by uneven positioning force of the aluminum sheet can be effectively prevented, and the four sides of the aluminum sheet can be ensured to be parallel to the four sides of the supporting plate after placement, thereby ensuring the stability and uniformity of the placement.

[0012] Furthermore, the first regulating body includes a housing provided at the lower end of the supporting plate, a threaded rod provided in the housing and passing through one end of the housing, a regulating valve connected to one end of the threaded rod passing through the housing, a first limiting body adjacent to the regulating valve and movably connected to the threaded rod, and a second limiting body movably connected to the other end of the threaded rod; the left and right threads of the threaded rod are opposite threads. The first limiting body includes a first moving block movably connected to the threaded rod, a second limiting post connected to both ends of the first moving block; the second limiting post moves within the first limiting groove; the second limiting body includes a second moving block movably connected to the threaded rod, a third limiting post fixedly connected to both ends of the second moving block; the third limiting post moves within the second limiting groove;

[0013] The first movable block is provided with a thread groove that cooperates with the thread on the threaded rod. The shell is set to improve stability during the adjustment process. Through the above-mentioned setting, the adjustment process of the first adjusting body is as follows: after the aluminum sheet is placed on the supporting plate next to the first limiting column, the regulating valve is manually rotated to rotate the threaded rod, and by setting the thread on one side of the threaded rod to the opposite thread, the rotation of the threaded rod drives the first movable block and the second movable block to move closer, thereby driving the second limiting column to approach the front edge of the aluminum sheet and the third limiting column to approach the rear edge of the aluminum sheet, so as to limit the aluminum sheet to the desired position. The aluminum sheet has high precision, simple and quick operation, strong practicality, and effectively improves work efficiency. Before the aluminum sheet is placed on the supporting plate, the regulating valve is rotated to make the first movable block and the second movable block move away from each other, that is, the position of the first limiting groove where the second limiting column is located and the position of the second limiting groove where the third limiting column is located are the longest straight-line distance, which is convenient for placing the aluminum sheet and easy operation.

[0014] The first movable block has fixed slots at both ends corresponding to the second limiting posts, with a magnet centered within the fixing slots. The lower end of the second limiting post is inserted between the fixing slots and the magnet, and an iron sheet is embedded in the inner wall of the lower end of the second limiting post. This arrangement allows the second limiting post to be pulled upward before the aluminum sheet is placed on the support plate, freeing it from the magnet's attraction and allowing it to exit the fixing slots. This effectively reduces the height required to lift the aluminum sheet onto the support plate. Once the sheet is placed, the second limiting post is inserted into the fixing slots and secured with magnets. This effectively saves effort, makes the operation quick and easy, and is convenient to operate, improving the stability of the aluminum sheet placement and making it highly practical.

[0015] Furthermore, the second adjusting body includes a support seat provided at the lower end of the third limiting groove, slide rails provided on both sides of the support seat, and a third limiting body movably connected to the slide rails. The third limiting body includes a third moving block movably connected to the slide rails, a fourth limiting column provided on one side of the upper end of the third moving block, and a tension valve provided on the other side of the upper end of the third moving block.

[0016] With this arrangement, the adjustment process of the second adjusting body is as follows: after adjusting the front and rear edges of the aluminum sheet, the aluminum sheet is limited by the second adjusting body relative to the other side of the first limiting column, the loosening valve is screwed, and the fourth limiting column is moved to slide close to the edge of the aluminum sheet. When the fourth limiting column is close to the edge of the aluminum sheet, it stops and the loosening valve is tightened accordingly, thereby fixing the third movable block to the corresponding position of the support seat. In the sliding process, the force exerted by the fourth limiting column drives the third movable block to slide on the support seat, wherein the sliding action is performed by the existing slide rail slider. The loosening and tightening are achieved by rotating the loosening valve and are fixed by the existing bolt thread. The overall operation is simple, the operation is convenient and efficient, and the work efficiency is effectively improved.

[0017] The tension valve is equipped with anti-slip silicone patterns on its surface. This makes it easier to turn the valve, improving the anti-slip properties of the operation, making it easy to operate and highly practical. The silicone anti-slip patterns also effectively improve the comfort of the operator.

[0018] Furthermore, a fourth limiting slot is provided on one side of the support plate; the upper pin assembly also includes a second positioning mechanism; the second positioning mechanism moves within the fourth limiting slot. The second positioning mechanism includes a guide rod connected to the lower end of the support plate, a fourth movable block movably connected to the guide rod, and a positioning block fixedly connected to the upper end of the fourth movable block. The positioning block has a fixing hole on one side, and a threaded groove is provided within the fixing hole; the threaded groove is configured to engage with a bolt for secure connection.

[0019] This setup allows for a double positioning of stacked wooden backing plates and copper sheets. The second positioning mechanism operates as follows: the wooden backing plate is positioned using positioning pins. Once the wooden backing plate is in place, the positioning block is moved toward the wooden backing plate until it touches the edge. The positioning block is then locked by inserting bolts into the fixing holes. The copper sheet is then placed against the positioning block, and the sheet is laid flat, allowing the holes in the copper sheet to be inserted into the positioning pins. This makes the operation simpler and more efficient, allowing for quick alignment of boards of the same size, significantly reducing the time required to insert positioning pins. The positioning block moves via a fourth moving block that slides on a guide rod, which in turn drives the movement of the positioning block.

[0020] Among them, the positioning block is set in an inverted L-shaped positioning block, which ensures the locking force of the positioning block and improves the stability and firmness of the positioning block.

[0021] Furthermore, it also includes a rubber-coated component arranged between the upper aluminum sheet component and the upper pin component, a flip component arranged on one side of the upper aluminum sheet component, a blanking component arranged on one side of the flip component, and a straight-line conveying component running through the rubber-coated component to the flip component.

[0022] Furthermore, the first transfer mechanism is movable between the rubber-coated component and the storage mechanism; the upper pin components are symmetrically arranged, and a lifting and conveying component is provided between the upper pin components; the rubber-coated component is symmetrically provided with a rubber-coated machine and a lifting and rotating machine provided between the rubber-coated machines on both sides; the unloading component includes a plate receiving body and a second transfer mechanism movable between the plate receiving body and the flipping component.

[0023] The flipping component is used to flip the wooden backing plate or the aluminum plate upward, depending on the placement of the plates in the blanking component. That is, when placing the first plate, the wooden backing plate faces downward and the aluminum plate faces upward. The second plate needs to face the aluminum plate downward and the wooden backing plate upward. The third plate needs to face the wooden backing plate downward and the aluminum plate upward. This method of flipping the plates in this way ensures that the wooden backing plate touches the aluminum plate, effectively preventing scratches on the aluminum plate and ensuring product quality.

[0024] The hemming machine operates as follows: a wooden backing sheet and a copper sheet are stacked sequentially on the upper pin assembly, and pins are simultaneously applied to both ends of the sheet. After pinning is completed, the lifting and conveying assembly is raised by a pneumatic cylinder, allowing the pinned wooden backing sheet and copper sheet to move toward the rubber-wrapped assembly. The lifting and conveying assembly then transfers the wooden backing sheet and copper sheet to the linear conveyor assembly, which then transfers them to the lifting and rotating mechanism and stops. The first transfer mechanism in the upper aluminum sheet assembly then picks up the aluminum sheet from the storage mechanism and transfers it over the copper sheet, thereby stacking the sheets. Once stacked, the rubber-wrapping machine moves to a position based on the sheet size to begin rubber-wrapping. After rubber-wrapping both sides of the sheet, the rubber-wrapping machines are moved to their maximum distance. The lifting and rotating mechanism then lifts the sheet, rotates it 90 degrees, and then descends to its original height. The rubber-wrapping machine then moves to a position based on the sheet size to begin rubber-wrapping all four edges of the sheet. After the rubber coating is completed, the linear conveyor again sends the plate to the flipping component, which flips the plate accordingly. After the flip is completed, the second transfer mechanism picks up the plate from the flipping component and sends it to the plate receiving body, thus completing the edge wrapping operation.

[0025] By installing a pinning component, wooden backing plates and copper sheets can be stacked and pinned sequentially, effectively eliminating the space required for separate loading of wooden backing plates and copper sheets. By stacking aluminum sheets on copper sheets on the rubberized components, the required space for stacking the individual sheets is eliminated. The rubberized sheeting can then be directly loaded after stacking, resulting in a streamlined and rapid process with a fast, efficient operation schedule, effectively saving time. This overall setup results in a compact structure, minimal footprint, simple and quick operation, and a streamlined process, effectively improving operational efficiency.

[0026] Beneficial effects of the present invention:

[0027] By setting up the upper pin parts and the upper aluminum sheet parts, the problem of low working efficiency caused by manual placement of the plates is solved, the precise alignment of manual stacking is improved, and a large amount of alignment time can be saved, and the alignment can be quickly placed, which effectively improves the efficiency of the hemming operation and is convenient and quick to operate.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0039] To facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and drawings.

[0040] like Figure 1-9As shown in , a semi-automatic hemming device provided by one embodiment of the present invention includes an upper pin component 1, an upper aluminum sheet component 2 provided on one side of the upper pin component 1; the upper pin component 1 includes an upper pin machine 11, a support plate 12 provided at the lower end of the upper pin machine 11, and a first positioning mechanism 13 provided at the lower end of the upper pin component 1; the upper pin machine 11 includes an upper pin mouth, the support plate 12 is provided with a guide hole 121 relative to the upper pin mouth; the first positioning mechanism 13 includes a positioning pin 131 provided relative to the guide hole 121, and a lifting body 132 connected to the lower end of the positioning pin 131; the upper pin mouth, the The guide hole 121 and the positioning pin 131 are on the same vertical line; the upper aluminum sheet component 2 includes a storage mechanism 21 and a first transfer mechanism 22 provided at the upper end of the storage mechanism 21; the storage mechanism 21 includes a supporting plate 211 and a first adjusting body 212 provided at the lower end of the supporting plate 211; one side of the supporting plate 211 is provided with a first limiting column 2111, a first limiting groove 2112 and a second limiting groove 2113 corresponding to the two ends of the first adjusting body 212 and symmetrically arranged to the first limiting column 2111; the first adjusting body 212 moves in the first limiting groove 2112 and the second limiting groove 2113.

[0041] In the present invention, the process of stacking the wooden pads and copper plates in sequence is as follows: before placing the wooden pads, the lifting body 132 is started, the positioning pin 131 is raised, the positioning pin 131 passes through the guide hole 121 and is exposed on the support plate 12, the hole of the wooden pad passes through the positioning pin 131, and the wooden pad is positioned; then the hole of the copper sheet passes through the positioning pin 131, and the copper sheet is accurately stacked on top of the wooden pad. After the alignment is completed, the upper pin machine 11 presses the copper sheet downward, and the positioning pin 131 is located at the upper pin mouth. The lifting body 132 moves downward, driving the positioning pin 131 to move downward to the bottom of the guide hole 121. The upper pin machine 11 then passes the pin out of the upper pin mouth and drives it into the holes of the wooden pads and the copper sheet, thereby completing the upper pinning operation. Through this setting, the time spent on alignment is greatly reduced, alignment is fast, and the efficiency of stacking wooden pads and copper sheets is effectively improved. The operation is convenient and quick, and the difficulty of stacking is reduced. The guide hole 121 allows for precise upward movement of the positioning pin 131, serving as a guide. During the pinning operation, the impact of the pin driving into the wooden backing plate and copper sheet is effectively cushioned, ensuring the quality of the pinning. The pinning opening, guide hole 121, and positioning pin 131 are arranged on the same vertical line to ensure alignment and consistent positioning of the pins, thus ensuring the quality of the pinning.

[0042] The manual aluminum sheet placement process is as follows: Adjust the first adjustment body 212 to its widest range, i.e., the longest straight-line distance between the first limiting slot 2112 and the second limiting slot 2113. Place the aluminum sheet on the support plate 211, close to the first limiting post 2111. Then, rotate the first adjustment body 212 to gradually narrow the range until the front and back edges of the aluminum sheet are positioned by the first adjustment body 212. This method effectively reduces deviations in sheet placement and improves accuracy. The simple and quick operation significantly reduces the time required for precise sheet placement, effectively improving sheet placement efficiency and shortening the hemming process, thereby increasing hemming production efficiency. Each action can be controlled by an existing PLC program.

[0043] Furthermore, the storage mechanism 21 further includes a second adjusting body 213 at the lower end of the other side of the supporting plate 211 ; the supporting plate 211 is provided with a third limiting groove 2114 corresponding to the second adjusting body 213 ; the second adjusting body 213 moves in the third limiting groove 2114 .

[0044] The second adjusting body 213 is used to limit the other side of the aluminum sheet relative to the first limiting post 2111. With this arrangement, after the first adjusting body 212 positions the aluminum sheet front and back, the second adjusting body 213 also limits the other side of the aluminum sheet, thereby limiting all four sides of the aluminum sheet. This further improves the accuracy of the aluminum sheet placement, effectively prevents deviation, and effectively ensures the accuracy and quality of subsequent stacking operations.

[0045] Among them, the first limiting column 2111 is symmetrically arranged with respect to the third limiting groove 2114. Through this arrangement, the tilting phenomenon caused by uneven positioning force of the aluminum sheet can be effectively prevented, and the four sides of the aluminum sheet can be ensured to be parallel to the four sides of the supporting plate 211 after being placed, thereby ensuring the stability and uniformity of the placement.

[0046] Furthermore, the first adjusting body 212 includes a shell 2121 arranged at the lower end of the supporting plate 211, a threaded rod 2122 arranged in the shell 2121 and passing through one end of the shell 2121, a regulating valve 2123 connected to one end of the threaded rod 2122 passing through the shell 2121, a first limiting body 2124 close to the regulating valve 2123 and movably connected to the threaded rod 2122, and a second limiting body movably connected to the other end of the threaded rod 2122; the left and right threads of the threaded rod 2122 are opposite threads. The first limiting body 2124 includes a first moving block movably connected to the threaded rod 2122, and a second limiting column 21242 connected to both ends of the first moving block; the second limiting column 21242 moves in the first limiting groove 2112; the second limiting body includes a second moving block 21251 movably connected to the threaded rod 2122, and a third limiting column 21252 fixedly connected to both ends of the second moving block 21251; the third limiting column 21252 moves in the second limiting groove 2113;

[0047] Among them, a thread groove is provided in the first moving block to cooperate with the thread on the threaded rod 2122. The setting of the shell 2121 is to improve the stability during the adjustment process. Through the above setting, the adjustment process of the first adjustment body 212 is: after the aluminum sheet is placed on the supporting plate 211 close to the first limiting column 2111, the regulating valve 2123 is manually rotated to rotate the threaded rod 2122, and by setting the thread on one side of the threaded rod 2122 and the thread on the other side to be opposite threads, the rotation of the threaded rod 2122 drives the first moving block and the second moving block 21251 to move closer, thereby driving the second limiting column 21242 close to the front edge of the aluminum sheet, and the third limiting column 21252 close to the rear edge of the aluminum sheet, so as to limit the aluminum sheet to the desired position, with high precision, simple and quick operation, strong practicality, and effectively improving work efficiency. Before placing the aluminum sheet on the supporting plate 211, the regulating valve 2123 is rotated to make the first moving block and the second moving block 21251 move away from each other, so that the position of the first limiting groove 2112 where the second limiting column 21242 is located and the position of the second limiting groove 2113 where the third limiting column 21252 is located are at the longest straight-line distance, which is convenient for placing the aluminum sheet and easy operation.

[0048] The first movable block has fixed slots at both ends corresponding to the second limiting posts 21242, with a magnet centered within the fixing slot. The lower end of the second limiting post 21242 is inserted between the fixing slot and the magnet, and an iron sheet is embedded in the inner wall of the lower end of the second limiting post 21242. This arrangement allows the second limiting post 21242 to be pulled upward before the aluminum sheet is placed on the support plate 211, thereby freeing it from the magnetic attraction and allowing it to exit the fixing slot. This effectively reduces the height required to lift the aluminum sheet to the support plate 211. Once the aluminum sheet is placed, the second limiting post 21242 is inserted into the fixing slot and secured by the magnet. This effectively saves effort, makes the operation quick and easy, and is convenient to operate. It also improves the stability of the aluminum sheet placement and is highly practical.

[0049] Furthermore, the second adjusting body 213 includes a support seat provided at the lower end of the third limiting groove 2114, slide rails provided on both sides of the support seat, and a third limiting body movably connected to the slide rails. The third limiting body includes a third moving block 21331 movably connected to the slide rails, a fourth limiting post 21332 provided on one side of the upper end of the third moving block 21331, and a tension valve 21333 provided on the other side of the upper end of the third moving block 21331.

[0050] With this arrangement, the adjustment process of the second adjusting body 213 is as follows: after adjusting the front and rear edges of the aluminum sheet, the other side of the aluminum sheet relative to the first limiting post 2111 is again limited by the second adjusting body 213, the tensioning valve 21333 is loosened, and the fourth limiting post 21332 is moved to slide closer to the edge of the aluminum sheet. When the fourth limiting post 21332 is in close proximity to the edge of the aluminum sheet, it stops and the tensioning valve 21333 is tightened accordingly, thereby fixing the third movable block 21331 in the corresponding position of the support seat. During the sliding process, the force applied by the fourth limiting post 21332 drives the third movable block 21331 to slide on the support seat, wherein the sliding action is performed by the existing slide rail slider. The tensioning valve 21333 is rotated to achieve tension and release, and the tension and release are fixed by the existing bolt thread. The overall operation is simple, the operation is convenient and efficient, and the work efficiency is effectively improved.

[0051] The surface of the tension valve 21333 is equipped with anti-slip silicone anti-slip patterns. This design makes it easier to turn the tension valve 21333, improves the anti-slip performance during operation, and is easy to operate and highly practical. The anti-slip patterns are set as silicone anti-slip patterns, which effectively improves the comfort of operation.

[0052] Furthermore, a fourth limiting slot 122 is defined on one side of the support plate 12. The upper pin assembly 1 also includes a second positioning mechanism 14, which is movable within the fourth limiting slot 122. The second positioning mechanism 14 includes a guide rod 141 connected to the lower end of the support plate 12, a fourth movable block 142 movably connected to the guide rod 141, and a positioning block 143 fixedly connected to the upper end of the fourth movable block 142. A fixing hole 1431 is defined on one side of the positioning block 143, which has a threaded groove therein; the threaded groove is configured to engage with a bolt for securement.

[0053] Through this setting, the stacked wooden pads and copper sheets can be positioned twice. The use process of the second positioning mechanism 14 is as follows: the wooden pad is positioned and placed by using the positioning pin 131. After the wooden pad is placed, the positioning block 143 is moved toward the wooden pad until it is next to the edge of the wooden pad, and then the positioning block 143 is locked by inserting a bolt into the fixing hole 1431; then one side of the copper sheet is pressed against the positioning block 143, and then the copper sheet is laid flat and the hole of the copper sheet can be inserted into the positioning pin 131. The operation is simpler and more efficient, and the same size of plates can be quickly aligned, which greatly reduces the time for inserting the positioning pin 131, and is easy and quick. The positioning block 143 moves through the fourth moving block 142 to slide on the guide rod 141, thereby driving the movement of the positioning block 143.

[0054] The positioning block 143 is arranged in an inverted L-shape, which ensures the locking force of the positioning block 143 and improves the stability and firmness of the positioning block 143 .

[0055] Furthermore, it also includes a rubber-coated component 3 arranged between the upper aluminum sheet component 2 and the upper pin component 1, a flip component 4 arranged on one side of the upper aluminum sheet component 2, a blanking component 5 arranged on one side of the flip component 4, and a straight line conveying component running through the rubber-coated component 3 to the flip component 4.

[0056] Furthermore, the first transfer mechanism 22 is movable between the rubber-coated component 3 and the storage mechanism 21; the upper pin components 1 are symmetrically arranged, and a lifting and conveying component 6 is provided between the upper pin components 1; the rubber-coated component 3 is symmetrically provided with a rubber-coated machine and a lifting and rotating machine provided between the rubber-coated machines on both sides; the unloading component 5 includes a plate receiving body 51 and a second transfer mechanism 52 movable between the plate receiving body 51 and the flipping component 4.

[0057] The flipping component 4 is used to flip whether the wooden pad is facing upward or the aluminum sheet is facing upward, and flips according to the placement of the plates in the receiving plate body 51 in the blanking component 5. That is, when placing the first plate, the wooden pad faces downward and the aluminum sheet faces upward, the second plate needs to face the aluminum sheet downward and the wooden pad faces upward, and the third plate needs to face the wooden pad downward and the aluminum sheet faces upward, and the flipping cycle continues. This method places the wooden pads in contact with each other, effectively preventing scratches on the aluminum sheet and ensuring product quality.

[0058] The hemming machine operates as follows: a wooden backing sheet and a copper sheet are stacked sequentially on the upper pinning component 1, and pins are simultaneously applied to both ends of the wooden backing sheet and the copper sheet. After pinning is completed, the lifting and conveying component 6 is raised by a lifting cylinder, allowing the pinned wooden backing sheet and copper sheet to move toward the rubber-wrapped component 3. The lifting and conveying component 6 transfers the wooden backing sheet and the copper sheet to the linear conveying component, which then stops after transferring them to the lifting and rotating machine. The first transfer mechanism 22 in the upper aluminum sheet component 2 picks up the aluminum sheet from the storage mechanism 21 and transfers it above the copper sheet, thereby stacking the aluminum sheets. After stacking is completed, the rubber-wrapping machine moves to a position based on the size of the sheet to begin rubber-wrapping. After rubber-wrapping both sides of the sheet, the distance between the rubber-wrapping machines is maximized. The lifting and rotating machine then lifts the sheet, rotates it 90 degrees, and then descends to its original height. The rubber-wrapping machine then moves to a position based on the size of the sheet to begin rubber-wrapping on all four sides. After the rubber coating is completed, the linear conveying component again delivers the plate to the flipping component 4, which flips the plate accordingly. After the flip is completed, the second transfer mechanism 52 picks up the plate from the flipping component 4 and delivers it to the plate receiving body 51, thus completing the hemming operation.

[0059] By installing the upper pin component 1, wooden backing plates and copper sheets can be stacked and pinned sequentially, effectively eliminating the space required for separate loading of wooden backing plates and copper sheets. By stacking the aluminum sheet on the copper sheet on the rubberized component 3, the required stacking space for each sheet can be reduced. The rubberized sheet can then be directly loaded after stacking, resulting in a streamlined and rapid workflow with a fast operating cycle, effectively saving time. This overall setup results in a compact structure, a small footprint, simple and quick operation, and a streamlined process, effectively improving operational efficiency.

[0060] Beneficial effects of the present invention:

[0061] By setting the upper pin component 1 and the upper aluminum sheet component 2, the problem of low operating efficiency caused by manual placement of the plates is solved, the precise alignment of manual stacking is improved, and a large amount of alignment time can be saved, and the alignment can be quickly placed, which effectively improves the efficiency of the hemming operation and is convenient and quick to operate.
