A formwork recycling and cleaning device for construction sites

Abstract

The present invention relates to the technical field of form cleaning, and specifically relates to a form recycling and cleaning device for construction sites, which includes a bottom plate. A cleaning mechanism is installed above the bottom plate, and a displacement mechanism is installed at the bottom of the cleaning mechanism. The cleaning mechanism includes a second motor. The output end of the second motor is an elliptical cylinder. A threaded sleeve is slidably installed outside the output end of the second motor, and a disc is threadedly installed outside the threaded sleeve. An L-shaped plate is adopted. The side in contact with the nails is comb-shaped. When the nails pass through the L-shaped plate, they enter the inside of the L-shaped plate and shake together with the L-shaped plate, causing the nails to loosen and reduce the frictional resistance with the form, making it easier to pull out the nails. The nails that are not pulled out continue to move forward and reach the root of the comb shape of the L-shaped plate. At this time, the nails and the L-shaped plate are in a rigid pulling state, that is, the L-shaped plate rigidly pulls out the nails, replacing the rigid clamping of the nail puller, reducing the damage to the form, increasing the number of times the form can be recycled, and reducing the construction cost.

Description

Technical Field

[0001] The invention relates to the technical field of template cleaning, in particular to a template recovery and cleaning device used in construction sites. Background Art

[0002] Formwork used on construction sites is a common auxiliary tool used in construction sites. It is used to support concrete pouring and is a temporary support structure, mostly made of wood. Workers use multiple formworks to enclose an open rectangle. Nails are often used to reinforce the connection between adjacent formworks. When they are later dismantled, nails will remain on the wooden boards. In order to recycle the formwork and reduce construction costs, workers need to manually pull out the nails, which is time-consuming and labor-intensive. It is not suitable for recycling large quantities of formworks on construction sites. Alternatively, nail pullers are used to pull out nails embedded in the formworks. During operation, since the formworks are made of wood, the nail pullers rigidly contact the formworks, which may damage the formwork surface during clamping and pulling out nails, reducing the number of times the formworks can be recycled and hindering construction costs. In addition, most nail pullers can only pull out one nail per operation, which is inefficient and not suitable for recycling large quantities of formworks on construction sites.

[0006] A groove is provided at the bottom of the electromagnet, and an L-shaped plate is slidably installed in the groove. The side of the L-shaped plate close to the second motor is comb-shaped. Cams are symmetrically installed at both ends of the L-shaped plate. The cam has two convex points, and the lines between the convex points of the two cams are perpendicular to each other.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) A template recycling and cleaning device for construction sites according to the present invention adopts an L-shaped plate. The side in contact with the nails is comb-shaped. When the nails pass through the L-shaped plate, they enter the interior of the L-shaped plate and shake with the L-shaped plate, causing the nails to loosen from the template and reducing the frictional resistance, making it easier to pull out the nails. The nails with relatively small frictional force with the template will move upward under the suction force of the electromagnet and adhere to the bottom of the electromagnet. The nails that have not been pulled out continue to move forward with the template. When they reach the root of the comb shape of the L-shaped plate, the nails are rigidly pulled by the L-shaped plate, that is, the L-shaped plate rigidly pulls out the nails, replacing the rigid contact between the nail puller and the template, reducing the damage to the template to a certain extent, increasing the number of times the template can be recycled, and reducing the construction cost.

[0017] (2) A template recycling and cleaning device for construction sites according to the present invention has the position where the L-shaped clamping plate contacts the template set to be inclined. Therefore, the L-shaped clamping plate will exert a downward pressure on the template, thereby causing the template to move downward, increasing the frictional force between the template and the suction cup, and enhancing the stability of the template.

[0018] (3) A template recycling and cleaning device for construction sites according to the present invention rotates and moves downward along the outside of the output end of the second motor through the piston plate and the threaded sleeve, thereby increasing the internal space of the suction cup and reducing the pressure. Under the pressure of the external atmospheric pressure, the adsorption force between the suction cup and the template is greater, further enhancing the stability of the template.

[0019] (4) A template recycling and cleaning device for construction sites according to the present invention adopts cams. Two cams alternately squeeze the L-shaped plate, causing the L-shaped plate to reciprocate horizontally. When the nails pass through the L-shaped plate, they enter the interior of the L-shaped plate and shake with the L-shaped plate, causing the nails to loosen from the template and reducing the frictional resistance, making it easier to pull out the nails.

Specific embodiments

[0032] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the present invention in combination with the accompanying drawings and the descriptions of the embodiments or the prior art. Obviously, the following descriptions of the structures of the accompanying drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but do not constitute a limitation to the present invention.

[0033] First embodiment:

[0034] As Figure 1-6 and Figure 8As shown in the figure, an embodiment of the present invention provides a template recycling and cleaning device for construction sites, including a bottom plate 1. Above the bottom plate 1, a cleaning mechanism 3 is installed. At the bottom of the cleaning mechanism 3, a displacement mechanism 2 is installed for the translation of the cleaning mechanism 3.

[0035] The cleaning mechanism 3 includes a second motor 38. The output end of the second motor 38 is an elliptical cylinder. A threaded sleeve 320 is slidably installed outside the output end of the second motor 38. A disc 37 is threadedly installed outside the threaded sleeve 320. The connection between the threaded sleeve 320 and the disc 37 is treated with frosting to increase the friction between the threaded sleeve 320 and the disc 37. Four crescent blocks 36 are evenly and fixedly installed outside the disc 37. A card slot 35 is opened outside the crescent block 36. A sleeve rod 318 is slidably clamped in the card slot 35. The sleeve rod 318 can slide in the card slot 35 but will not break away from the connection. Above the sleeve rod 318, a hollow square plate 324 is installed. A moving rod 32 is slidably installed inside the sleeve rod 318. A spring 319 is fixedly installed between the end of the moving rod 32 and the inner side of the sleeve rod 318. The spring 319 is in a stretched state. The spring 319 makes the moving rod 32 and the sleeve rod 318 elastically connected, that is, the lengths of the two are variable, so as to adapt to objects to be clamped with different sizes within a certain range. At the top of the moving rod 32, an L-shaped clamping plate 33 is fixedly installed. An electromagnet 312 is installed above the L-shaped clamping plate 33. A template 316 is movably installed between the four L-shaped clamping plates 33. A plurality of nails 317 are slidably penetrated through the middle of the template 316. The hollow square plate 324 is located below the L-shaped clamping plate 33. There is a certain gap between the hollow square plate 324 and the L-shaped clamping plate 33 to prevent the nails 317 from being bent and embedded in the template 316, which is not convenient for subsequent manual extraction.

[0036] In this embodiment, as Figure 1 shown, the staff starts the second motor 38. The second motor 38 drives the threaded sleeve 320, the air chamber 310, and the disc 37 to rotate clockwise, and then drives the crescent block 36 to rotate clockwise. The distal end of the crescent block 36 gradually contacts the sleeve rod 318, and then the sleeve rod 318 gradually moves away from the second motor 38, and the spring 319 is compressed. The sleeve rod 318 pushes the moving rod 32 and the L-shaped clamping plate 33 away from the second motor 38 through the compressed spring 319, that is, the space between the four L-shaped clamping plates 33 expands; when the second motor 38 is started in the reverse direction, the second motor 38 drives the threaded sleeve 320, the air chamber 310, and the disc 37 to rotate counterclockwise, and then drives the crescent block 36 to rotate counterclockwise. The proximal end of the crescent block 36 gradually contacts the sleeve rod 318, and then the sleeve rod 318 gradually approaches the second motor 38, and the spring 319 is stretched. The sleeve rod 318 pulls the moving rod 32 and the L-shaped clamping plate 33 close to the second motor 38 through the compressed spring 319, that is, the space between the four L-shaped clamping plates 33 shrinks, and the template 316 is clamped.

[0037] A groove is provided at the bottom of the electromagnet 312. An L-shaped plate 323 is slidably installed in the groove. One side of the L-shaped plate 323 close to the second motor 38 is comb-shaped, which is convenient for clamping the nail 317. Cam 322s are symmetrically installed at both ends of the L-shaped plate 323. The cam 322 has two convex points. The connection lines between the convex points of the two cam 322s are perpendicular to each other. When the two cam 322s rotate, they alternately squeeze the L-shaped plate 323, causing the L-shaped plate 323 to move reciprocally. A rotating column 321 is fixedly installed at the bottom of the cam 322. The bottom of the rotating column 321 is rotatably installed on the top of the bottom plate 1. A gear 315 is fixedly installed on the outer side of the rotating column 321. A rack 314 is meshingly installed on one side of the gear 315 close to the second motor 38. When the rack 314 moves, it can drive the gear 315 to rotate, and then drive the rotating column 321 and the cam 322 to rotate. The height of the nail 317 lifted by the hollow square plate 324 is slightly higher than the height of the comb-shaped position of the L-shaped plate 323, so that the lifted nail 317 can enter the inside of the comb-shaped part of the L-shaped plate 323, and the gap between the combs is larger than the cylindrical diameter of the nail 317 and smaller than the diameter of the nail cap of the nail 317.

[0038] In this embodiment, when the template 316 moves downward, it drives the nail 317 to move downward and squeeze the hollow square plate 324. When the nail 317 moves upward, it exposes the template 316. The first motor 21 is started, and the electromagnet 312 is energized to generate magnetism. The first motor 21 rotates to drive the lead screw 22 to rotate, and then drives the moving block 23 and the rack 314, template 316, nail 317, pressure sensor 44 and collection funnel 41 above it to move towards the electromagnet 312. The movement of the rack 314 drives the cam 322 to rotate. The two cam 322s alternately squeeze the L-shaped plate 323, causing the L-shaped plate 323 to reciprocally translate. When the nail 317 passes through the L-shaped plate 323, it enters the inside of the L-shaped plate 323 and shakes with the L-shaped plate 323, causing the nail 317 to become loose from the template 316 and reducing the frictional resistance, making it easier to pull out the nail 317. The nail 317 with a smaller frictional force with the template 316 will move upward under the suction force of the electromagnet 312 and adhere to the bottom of the electromagnet 312. The nails 317 that have not been pulled out continue to move forward and reach the root of the comb-shaped part of the L-shaped plate 323. At this time, the nail 317 and the L-shaped plate 323 are in a rigid pulling state, that is, the L-shaped plate 323 rigidly pulls out the nail 317. The pulled-out nails 317 are adsorbed on the bottom of the electromagnet 312. The remaining few nails 317 that have not been pulled out and are bent are manually cleaned up secondarily.

[0039] Second Embodiment:

[0040] As Figure 1-10 shown, an embodiment of the present invention provides a template recycling and cleaning device for construction sites, including a bottom plate 1. A cleaning mechanism 3 is installed above the bottom plate 1. A displacement mechanism 2 is installed at the bottom of the cleaning mechanism 3 for the translation of the cleaning mechanism 3;

[0041] The cleaning mechanism 3 includes a second motor 38. The output end of the second motor 38 is an elliptical cylinder. A threaded sleeve 320 is slidably installed outside the output end of the second motor 38. A disc 37 is threadedly installed outside the threaded sleeve 320. The connection between the threaded sleeve 320 and the disc 37 is treated with frosting to increase the friction between the threaded sleeve 320 and the disc 37. Four crescent blocks 36 are evenly and fixedly installed outside the disc 37. A card slot 35 is opened outside the crescent block 36. A sleeve rod 318 is slidably clamped in the card slot 35. The sleeve rod 318 can slide in the card slot 35 but will not disconnect. A hollow square plate 324 is installed above the sleeve rod 318. A moving rod 32 is slidably installed inside the sleeve rod 318. A spring 319 is fixedly installed between the end of the moving rod 32 and the inner side of the sleeve rod 318. The spring 319 is in a stretched state. The spring 319 elastically connects the moving rod 32 and the sleeve rod 318, that is, the lengths of the two are variable, so as to adapt to objects to be clamped with different sizes within a certain range. An L-shaped clamping plate 33 is fixedly installed at the top of the moving rod 32. An electromagnet 312 is installed above the L-shaped clamping plate 33. A template 316 is movably installed between the four L-shaped clamping plates 33. A plurality of nails 317 are slidably installed through the middle of the template 316.

[0042] A groove is opened at the bottom of the electromagnet 312. An L-shaped plate 323 is slidably installed in the groove. The side of the L-shaped plate 323 close to the second motor 38 is comb-shaped, which is convenient for clamping the nails 317. Two cams 322 are symmetrically installed at both ends of the L-shaped plate 323. The cams 322 have two convex points. The connection lines between the convex points of the two cams 322 are perpendicular to each other. When the two cams 322 rotate, they alternately squeeze the L-shaped plate 323, causing the L-shaped plate 323 to move reciprocally. A rotating column 321 is fixedly installed at the bottom of the cam 322. The bottom of the rotating column 321 is rotatably installed on the top of the bottom plate 1. A gear 315 is fixedly installed outside the rotating column 321. A rack 314 is meshingly installed on the side of the gear 315 close to the second motor 38. When the rack 314 moves, it can drive the gear 315 to rotate, and then drive the rotating column 321 and the cam 322 to rotate.

[0043] Specifically, an air chamber 310 is fixedly installed at the top of the disc 37. A suction cup 311 is fixedly installed at the top of the air chamber 310. A piston plate 39 is slidably installed inside the air chamber 310. The piston plate 39 is used to change the air pressure between the suction cup 311 and the template 316. The piston plate 39 is fixedly installed at the top of the threaded sleeve 320. The threaded sleeve 320 penetrates through the disc 37.

[0044] In this embodiment, the space between the four L-shaped clamping plates 33 is enlarged. The staff places the template 316 on the suction cup 311 and reversely starts the second motor 38. The space between the four L-shaped clamping plates 33 is reduced to clamp the template 316. After the end of the clamping groove 35 of the crescent block 36 contacts the sleeve rod 318, the rotational movement of the crescent block 36 and the disc 37 is rigidly blocked by the sleeve rod 318 and cannot continue to rotate. However, the output end of the second motor 38 continues to rotate, so that the piston plate 39 and the threaded sleeve 320 rotate and move downward along the outside of the output end of the second motor 38, thereby increasing the internal space of the suction cup 311 and reducing the pressure. Under the pressure of the external atmospheric pressure, the adsorption force between the suction cup 311 and the template 316 is greater, and the template 316 is more stable.

[0045] Specifically, the L-shaped clamping plate 33 is trapezoidal with a wider upper end. A plurality of rubber strips 34 are fixedly installed on both sides of the L-shaped clamping plate 33 close to the template 316. The rubber strips 34 are triangular with the tips facing downward. The resistance of the L-shaped clamping plate 33 sliding downward along the rubber strips 34 is much smaller than the resistance of sliding upward, thereby enhancing the clamping stability of the L-shaped clamping plate 33 to the template 316.

[0046] In this embodiment, during the process of the four L-shaped clamping plates 33 clamping the template 316, since the contact position between the L-shaped clamping plate 33 and the template 316 is inclined, the L-shaped clamping plate 33 will give the template 316 a downward pressure, thereby causing the template 316 to move downward, increasing the friction between the template 316 and the suction cup 311, and enhancing the stability of the template 316.

[0047] Third Embodiment:

[0048] As Figure 1-10 shown, the embodiment of the present invention provides a template recycling and cleaning device for a construction site, including a bottom plate 1. A cleaning mechanism 3 is installed above the bottom plate 1, and a displacement mechanism 2 is installed at the bottom of the cleaning mechanism 3 for the translation of the cleaning mechanism 3;

[0049] The cleaning mechanism 3 includes a second motor 38. The output end of the second motor 38 is an elliptical cylinder. A threaded sleeve 320 is slidably installed outside the output end of the second motor 38. A disc 37 is threadedly installed outside the threaded sleeve 320. The connection between the threaded sleeve 320 and the disc 37 is treated with frosting to increase the friction between the threaded sleeve 320 and the disc 37. Four crescent blocks 36 are evenly and fixedly installed outside the disc 37. A clamping groove 35 is formed outside the crescent block 36. A sleeve rod 318 is slidably clamped in the clamping groove 35. The sleeve rod 318 can slide in the clamping groove 35 but will not break away from the connection. A hollow square plate 324 is installed above the sleeve rod 318. A moving rod 32 is slidably installed inside the sleeve rod 318. A spring 319 is fixedly installed between the end of the moving rod 32 and the inner side of the sleeve rod 318. The spring 319 is in a stretched state. The spring 319 elastically connects the moving rod 32 and the sleeve rod 318, that is, the lengths of the two are variable, so as to adapt to objects to be clamped with different sizes within a certain range. An L-shaped clamping plate 33 is fixedly installed at the top of the moving rod 32. An electromagnet 312 is installed above the L-shaped clamping plate 33. A template 316 is movably installed between the four L-shaped clamping plates 33. A plurality of nails 317 are slidably installed through the middle of the template 316.

[0050] A groove is formed at the bottom of the electromagnet 312. An L-shaped plate 323 is slidably installed in the groove. The side of the L-shaped plate 323 close to the second motor 38 is comb-shaped, which is convenient for clamping the nails 317. Two cams 322 are symmetrically installed at both ends of the L-shaped plate 323. The cams 322 have two convex points. The connection lines between the respective convex points of the two cams 322 are perpendicular to each other. When the two cams 322 rotate, they alternately squeeze the L-shaped plate 323, causing the L-shaped plate 323 to move reciprocally. A rotating column 321 is fixedly installed at the bottom of the cam 322. The bottom of the rotating column 321 is rotatably installed on the top of the bottom plate 1. A gear 315 is fixedly installed outside the rotating column 321. A rack 314 is meshingly installed on the side of the gear 315 close to the second motor 38. When the rack 314 moves, it can drive the gear 315 to rotate, and then drive the rotating column 321 and the cam 322 to rotate.

[0051] Specifically, four L-shaped rods 31 are evenly and fixedly installed outside the second motor 38 to limit the movement track of the sleeve rod 318. The rack 314 is fixedly installed at the bottom position outside the L-shaped rod 31 through a support rod. The hollow square plate 324 is fixedly installed at the top position outside the L-shaped rod 31 through a support rod. The sleeve rod 318 is slidably installed in the middle of the top end of the L-shaped rod 31, and the sleeve rod 318 penetrates through the top end of the L-shaped rod 31.

[0052] Specifically, the displacement mechanism 2 includes a moving block 23. The moving block 23 is fixedly installed at the bottom of the second motor 38. A lead screw 22 is threadedly connected to the middle of the moving block 23. One end of the lead screw 22 is fixedly installed with a first motor 21. The other end of the lead screw 22 is rotatably installed on a fixed plate 25. The bottom of the fixed plate 25 is fixedly installed on the top of the bottom plate 1. The bottom of the first motor 21 is fixedly installed on the top of the bottom plate 1. A clamping block 24 is fixedly installed at the bottom of the moving block 23, which is used to offset the rotational force of the moving block 23 from the lead screw 22, so that the moving block 23 makes a translational motion. A chute slidably matched with the clamping block 24 is opened on the top of the bottom plate 1.

[0053] In this embodiment, as Figure 1 shown, the staff starts the first motor 21 and energizes the electromagnet 312 to magnetize it. The rotation of the first motor 21 drives the rotation of the lead screw 22, which in turn drives the moving block 23 and the template 316 and nails 317 above it to move towards the electromagnet 312.

[0054] Specifically, a collection mechanism 4 is installed on one side of the cleaning mechanism 3. The collection mechanism 4 includes a fixed rod 42. The fixed rod 42 is fixedly installed on the outside of the second motor 38. A collection funnel 41 is fixedly installed at the end of the fixed rod 42 away from the second motor 38. The dropped nails 317 can quickly slide towards the external collection device through the collection funnel 41, preventing them from being adsorbed by the electromagnet 312 again. Moreover, timely cleaning of the nails 317 adsorbed at the bottom of the electromagnet 312 can also ensure the adsorption efficiency of the electromagnet 312. A fixed block 43 is fixedly installed on one side of the collection funnel 41. A pressure sensor 44 is fixedly installed on the side of the fixed block 43 close to the electromagnet 312. The pressure sensor 44 is electrically connected to the first motor 21 and the pressure sensor 44 is electrically connected to the electromagnet 312. An extended receiving platform is arranged on one side of the top of the collection funnel 41 close to the electromagnet 312.

[0055] In this embodiment, the rotation of the first motor 21 drives the rotation of the lead screw 22, which in turn drives the moving block 23 and the template 316, nails 317, pressure sensor 44 and collection funnel 41 above it to move towards the electromagnet 312. When the pressure sensor 44 moves and touches the rightmost support column 313, the pressure sensor 44 sends an electrical signal to the first motor 21 and the electromagnet 312. The first motor 21 stops rotating and the electromagnet 312 is powered off. At this time, the extended receiving platform of the collection funnel 41 is located directly below the electromagnet 312. The nails 317 at the bottom of the electromagnet 312 fall and slide into the collection funnel 41, and then slide towards the collection device.

[0056] In this embodiment, when the pressure sensor 44 moves and touches the rightmost support column 313, the pressure sensor 44 sends an electrical signal to the first motor 21 and the electromagnet 312 through the data processor. The first motor 21 stops rotating, and the electromagnet 312 is powered off. At this time, the extended receiving platform of the collection funnel 41 is located directly below the electromagnet 312. The nail 317 at the bottom of the electromagnet 312 falls and slides into the collection funnel 41, and then slides towards the collection device.

[0057] Specifically, a support column 313 is fixedly installed between the electromagnet 312 and the bottom plate 1 for fixing the electromagnet 312.

[0058] Specific working method:

[0059] Clamping of the template 316, as Figure 1 shown, the staff starts the second motor 38. The second motor 38 drives the threaded sleeve 320, the air chamber 310, and the disc 37 to rotate clockwise, thereby driving the crescent block 36 to rotate clockwise. The distal end of the crescent block 36 gradually contacts the sleeve rod 318, thereby causing the sleeve rod 318 to gradually move away from the second motor 38. The spring 319 is compressed. The sleeve rod 318 pushes the moving rod 32 and the L-shaped clamping plate 33 away from the second motor 38 through the compressed spring 319, that is, the space between the four L-shaped clamping plates 33 expands;

[0060] The staff places the template 316 on the suction cup 311 and reversely starts the second motor 38. The second motor 38 drives the threaded sleeve 320, the air chamber 310, and the disc 37 to rotate counterclockwise, thereby driving the crescent block 36 to rotate counterclockwise. The proximal end of the crescent block 36 gradually contacts the sleeve rod 318, thereby causing the sleeve rod 318 to gradually approach the second motor 38. The spring 319 is stretched. The sleeve rod 318 pulls the moving rod 32 and the L-shaped clamping plate 33 close to the second motor 38 through the compressed spring 319, that is, the space between the four L-shaped clamping plates 33 shrinks, clamping the template 316. Since the position where the L-shaped clamping plate 33 contacts the template 316 is inclined, the L-shaped clamping plate 33 will give the template 316 a downward pressure, thereby causing the template 316 to move downward, increasing the friction between the template 316 and the suction cup 311, and enhancing the stability of the template 316. The downward movement of the template 316 drives the nail 317 to move downward and squeeze the hollow square plate 324, and the nail 317 moves upward to expose the template 316. When the end of the card slot 35 of the crescent block 36 contacts the sleeve rod 318, the rotational movement of the crescent block 36 and the disc 37 is rigidly blocked by the sleeve rod 318 and cannot continue to rotate. However, the output end of the second motor 38 continues to rotate, thereby causing the piston plate 39 and the threaded sleeve 320 to rotate and move downward along the outside of the output end of the second motor 38, thereby increasing the internal space of the suction cup 311 and reducing the pressure. Under the pressure of the external atmospheric pressure, the adsorption force between the suction cup 311 and the template 316 is greater, and the template 316 is more stable.

[0061] Clean the nails 317. As Figure 1 shown, the staff starts the first motor 21 and energizes the electromagnet 312 to magnetize it. The first motor 21 rotates to drive the lead screw 22 to rotate, and then drives the moving block 23 and the rack 314, template 316, nails 317, pressure sensor 44 and collection funnel 41 above it to move towards the electromagnet 312. The movement of the rack 314 drives the cam 322 to rotate. The two cams 322 alternately squeeze the L-shaped plate 323, causing the L-shaped plate 323 to reciprocate horizontally. When the nail 317 passes through the L-shaped plate 323, it enters the inside of the L-shaped plate 323 and shakes with the L-shaped plate 323, causing the nail 317 to become loose from the template 316 and reducing the frictional resistance, making the nail 317 easier to pull out. The nails 317 with relatively small frictional force with the template 316 will move upward under the suction force of the electromagnet 312 and adhere to the bottom of the electromagnet 312. The nails 317 that have not been pulled out continue to move forward and reach the comb-shaped root of the L-shaped plate 323. At this time, the nail 317 and the L-shaped plate 323 are in a rigid tug-of-war, that is, the L-shaped plate 323 rigidly pulls out the nail 317. The pulled-out nails 317 are adsorbed on the bottom of the electromagnet 312. When the pressure sensor 44 moves and touches the rightmost support column 313, the pressure sensor 44 sends an electrical signal to the first motor 21 and the electromagnet 312. The first motor 21 stops rotating, and the electromagnet 312 is de-energized. At this time, the extended receiving platform of the collection funnel 41 is located directly below the electromagnet 312. The nails 317 at the bottom of the electromagnet 312 fall and slide into the collection funnel 41, and then slide towards the collection device;

[0062] The staff energizes the electromagnet 312 to magnetize it again and reversely starts the first motor 21. The template 316 and the nails 317 that have not been removed move backward and reset. The staff starts the second motor 38 again. Since the adsorption force between the suction cup 311 and the template 316 is relatively large, the suction cup 311 cannot rotate relative to the template 316, that is, the disc 37 cannot rotate. However, the output end of the second motor 38 continues to rotate, causing the piston plate 39 and the threaded sleeve 320 to rotate and move downward along the outside of the output end of the second motor 38. As a result, the internal space of the suction cup 311 is restored and the pressure is restored, reducing the adsorption force between the suction cup 311 and the template 316. At this time, relative rotation can occur between the suction cup 311 and the template 316. The crescent block 36 rotates clockwise, and the distal end of the crescent block 36 gradually contacts the sleeve rod 318, causing the sleeve rod 318 to gradually move away from the second motor 38. The spring 319 is compressed. The sleeve rod 318 pushes the moving rod 32 and the L-shaped clamping plate 33 away from the second motor 38 through the compressed spring 319, that is, the space between the four L-shaped clamping plates 33 expands. The staff takes out the template 316 and then places the subsequent template 316 to be processed on the suction cup 311.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
