Description

Technical Field

[0001] This invention relates to the field of lifting device separation technology, and in particular to a separation device for automotive sheet stamping parts. Background Technology

[0002] Automotive body-in-white sheet metal stampings are essential components for car body manufacturing. During mass production and transfer, they are typically stored and transported in a stacked manner. Due to the production process, the sheet metal surfaces are smooth and coated with stamping oil. The combined stacking and extrusion action easily creates a tight bond and vacuum adhesion between the layers, posing significant challenges to destacking and unloading operations.

[0003] The existing destacking operations for thin sheet stamping parts mostly adopt a purely manual operation mode. The sheet layers are prone to sticking and adhering, making it difficult to separate individual pieces. When workers disassemble and lift the parts, they often need to bend over to pry and lift them under heavy loads, resulting in high labor intensity, low destacking efficiency, and extremely high manpower consumption.

[0004] Therefore, the existing separation and hoisting devices cannot specifically solve the problem of interlayer adhesion of thin stamped parts. When the whole sheet is lifted, the sheet remains in a close-fitting state and cannot form an effective separation gap. As a result, manual prying is still required when unstacking, resulting in poor separation effect and low work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a separation device for automotive sheet stamping parts, so as to solve the technical problem in the prior art that an effective separation gap cannot be formed and manual prying is required.

[0010] Furthermore, the linear cylinder assembly also includes a bending plate, the horizontal section of which is arranged parallel to the piston rod, and the two bent sections of the bending plate are fixed to the base plate and the L-shaped support, respectively.

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, the automotive sheet stamping separation device provided by the present invention includes: a bracket 1, a linear cylinder assembly 2, a traction assembly 3, a fixed pulley 4, a suction cup assembly 5, and a switch assembly 6; The linear cylinder assembly 2 is horizontally fixedly installed on the top of the bracket 1, the fixed pulley 4 is fixed on the bracket 1, one end of the traction assembly 3 is connected to the power end of the linear cylinder assembly 2, and the other end of the traction assembly 3 passes around the fixed pulley 4 and is fixedly connected to the suction cup assembly 5 below. The suction cup assembly 5 includes a connecting rod 501, a sliding bolt 502, an impact plate 503, a clamp 504, and a vacuum suction cup 505; the lower surface of the traction assembly 3 has a groove in the vertical direction, the connecting rod 501 is sleeved on the outside of the traction assembly 3 and slides along the groove through the sliding bolt 502 for buffering; the impact plate 503 is sleeved on the outer periphery of the connecting rod 501 and is used to impact the switch assembly 6 fixed on the bracket 1 when moving upward; the end of the traction assembly 3 is connected to the clamp 504 by bolts, and the vacuum suction cup 505 is fixed in the middle of the clamp 504.

[0030] Specifically, the linear cylinder assembly 2 is horizontally fixedly installed on the top of the bracket 1, the fixed pulley 4 is fixed at the end of the bracket 1, one end of the traction assembly 3 is connected to the power end of the linear cylinder assembly 2, and the other end of the traction assembly 3 passes around the fixed pulley 4 to complete the power reversal, extends downward in the vertical direction and is fixedly connected to the suction cup assembly 5 below; the suction cup assembly 5 includes a connecting rod 501, a sliding bolt 502, an impact plate 503, and a clamp 504. Along with the vacuum suction cup 505, the lower surface of the traction assembly 3 has a long strip-shaped groove opened in the vertical direction. The connecting rod 501 is coaxially sleeved on the outside of the traction assembly 3. The sliding bolt 502 passes through the connecting rod 501 laterally and extends into the groove to form a sliding limit fit. The impact plate 503 is fixedly sleeved on the outer periphery of the connecting rod 501. The switch assembly 6 is fixedly installed on the vertical side wall of the bracket 1 and is correspondingly set on the upward movement path of the impact plate 503. The end of the traction assembly 3 is fastened to the clamp 504 by bolts. The clamp 504 clamps and fixes the vacuum suction cup 505 in the center, so that the vacuum suction cup 505 maintains a vertical downward working posture.

[0031] The horizontal power of the linear cylinder assembly 2 is stably converted into vertical lifting power through the fixed pulley 4, driving the suction cup assembly 5 to complete the single-sided lifting and separation of the thin stamped part; the sliding cooperation between the connecting rod 501, the sliding bolt 502 and the sliding groove of the traction assembly 3 forms a buffer structure, allowing the vacuum suction cup 505 to adaptively float axially when it contacts the workpiece, avoiding scratches and deformation of the workpiece surface caused by rigid impact; the alignment of the impact plate 503 and the switch assembly 6 can detect the lifting height of the suction cup assembly 5 in real time, ensuring that the separation stroke meets the standard, the action is accurate and reliable, the overall device operates without shaking or deviation, and the separation efficiency is improved.

[0032] In embodiments of the present invention, such as Figure 2 As shown, the support 1 includes a first column 101, a square steel 102, a crossbeam 103, and a second column 104; The upper part of the first column 101 is slidably connected to the square steel 102 via a slide rail. A crossbeam 103 is vertically installed on the top of the square steel 102. A linear cylinder assembly 2 is installed above the crossbeam 103. A fixed pulley 4 is installed at the end of the crossbeam 103. The bottom of the end of the crossbeam 103 near the fixed pulley 4 is connected to the second column 104. A switch assembly 6 is fixedly installed on the side wall of the second column 104.

[0033] Specifically, the first column 101 is vertically arranged as a supporting body on one side. The upper part of the first column 101 is connected to the square steel 102 through a slide rail. The square steel 102 extends horizontally and is vertically fixed to the crossbeam 103, so that the crossbeam 103 is horizontally erected. The upper plane of the crossbeam 103 is used to install and fix the linear cylinder assembly 2. The fixed pulley 4 is fixedly assembled at the end of the crossbeam 103 away from the first column 101. The bottom of the end of the crossbeam 103 near the fixed pulley 4 is vertically fixedly connected to the second column 104. The second column 104 extends vertically downward to form the other side. The switch assembly 6 is fixedly installed on the side wall surface of the second column 104 in a vertical direction and is arranged according to the upward movement trajectory of the suction cup assembly.

[0034] The first column 101 is slidably connected to the slide rail of the square steel 102, so as to realize the flexible adjustment of the vertical height of the crossbeam 103 and the upper assembly components, which can be adapted to the separation operation of automotive sheet stamping parts with different stacking heights; the vertical assembly structure of the square steel 102 and the crossbeam 103 can ensure the stability of the horizontal installation of the linear cylinder assembly 2 and avoid tilting and shaking during power operation.

[0035] In embodiments of the present invention, such as Figure 3 , Figure 4 As shown, the linear cylinder assembly 2 includes a cylinder body 201, an L-shaped support 202, a piston rod 203, and a lug 204; the cylinder body 201 is fixed to the top of the bracket 1 away from the fixed pulley 4 by two L-shaped supports 202; the end of the piston rod 203 connected to the cylinder body 201 is fixedly connected to the lug 204, and the hook traction assembly 3 is wrapped around the lug 204.

[0036] The linear cylinder assembly 2 also includes a connecting block 205, a base plate 206, an L-shaped stop block 207, and a limiting block 208; two connecting blocks 205 are sleeved on the surface of the piston rod 203, the base plate 206 is located in the middle of the crossbeam 103, several through holes are opened on the surface of the base plate 206, the L-shaped stop block 207 is located on the surface of the base plate 206 through the through holes, and a limiting block 208 is provided on the side of the L-shaped stop block 207 facing the connecting block 205.

[0037] The linear cylinder assembly 2 also includes a bending plate 209. The horizontal section of the bending plate 209 is arranged parallel to the piston rod 203, and the two bent sections of the bending plate 209 are fixed on the base plate 206 and the L-shaped support 202, respectively.

[0038] Specifically, in the linear cylinder assembly 2, the cylinder body 201 is arranged horizontally. The cylinder body 201 is locked and fixed to the top of the bracket 1 away from the fixed pulley 4 by two L-shaped supports 202 arranged symmetrically at the front and rear, so that the cylinder body 201 maintains a horizontal and stable installation posture. The output end of the cylinder body 201 is connected to the piston rod 203. The piston rod 203 performs linear reciprocating extension and retraction motion in the horizontal direction. The extended end of the piston rod 203 is fixedly connected to the lug 204. The lug 204 serves as a power transfer component, and the external hook is connected to the traction assembly 3 to achieve stable power transmission. Two integral connecting blocks 205 are fitted onto the outer surface of the piston rod 203. The base plate 206 is horizontally fixedly installed in the middle of the crossbeam 103. Several equidistant through holes are opened on the surface of the base plate 206 along the extension and retraction direction of the piston rod 203 (the limit can be adjusted by bolts, a total of 12 adjustable holes). The L-shaped stop block 207 is detachably installed on the surface of the base plate 206 through the through holes. The end face of the L-shaped stop block 207 facing the connecting block 205 is fixedly installed with a limiting block 208, and the limiting block 208 and the connecting block 205 form a horizontal limiting fit. The linear cylinder assembly 2 also includes a bending plate 209, which is an integral bending structure. The horizontal section of the bending plate 209 is arranged parallel to the piston rod 203. The two bent sections of the bending plate 209 are respectively fixed on the base plate 206 and the L-shaped support 202 to guide and limit the piston rod 203.

[0039] The symmetrical fixing of the L-shaped support 202 ensures that the cylinder body 201 is firmly installed without loosening, and ensures that the piston rod 203 does not wobble during telescopic operation; the connecting block 205 sleeved on the piston rod 203 can guide the telescopic stroke and prevent the piston rod 203 from jamming; the multiple sets of through holes on the base plate 206 can make the positions of the L-shaped stop block 207 and the limiting block 208 adjustable, limiting the maximum extension stroke of the piston rod 203 and preventing the traction component 3 from being lowered too much and causing damage to the device; the bending plate 209 guides and limits the piston rod 203 to prevent the piston rod 203 from swaying or deviating to the left or right.

[0040] In embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the traction assembly 3 includes a wire rope 301, a counterweight 302, a chain 303, and a guide rod 304; one end of the wire rope 301 is hooked around the linear cylinder assembly 2, and the other end of the wire rope 301 passes over the fixed pulley 4 and is connected to the counterweight 302 through the lifting lug; the counterweight 302 is connected to the chain 303 through the lifting lug; and the end of the chain 303 is connected to the guide rod 304. A vertical groove is formed on the lower surface of the guide rod 304, and the end of the guide rod 304 is connected to the suction cup assembly 5. A guide support 305 is sleeved on the guide rod 304, and the fixed end of the guide support 305 is fixed to the bracket 1.

[0041] The fixed pulley 4 is fixed to the bracket 1 by the fixing frame 401, and a protective cover 402 is provided above the fixed pulley 4 by the bracket 1.

[0042] Specifically, one end of the wire rope 301 is hooked and connected to the lug 204 of the linear cylinder assembly 2. The other end of the wire rope 301 passes through the groove of the fixed pulley 4 and is fixedly connected to the counterweight 302 via a lifting lug. The bottom of the counterweight 302 is connected to the upper end of the chain 303 via a lifting lug. The end of the chain 303 is connected to the top of the guide rod 304. The lower surface of the guide rod 304 has a long strip-shaped groove in the vertical direction. The bottom end of the guide rod 304 is fixedly connected to the suction cup assembly 5. The guide support 305 is coaxially sleeved on the outside of the guide rod 304. The fixed end of the guide support 305 is locked and fixed to the vertical structure of the bracket 1. The fixed pulley 4 is locked and fixed to the end of the bracket 1 via a fixing bracket 401. A protective cover 402 is installed above the fixed pulley 4 at a corresponding position via the bracket 1. The protective cover 402 covers the outside of the fixed pulley 4.

[0043] The steel wire rope 301 works in conjunction with the fixed pulley 4 to achieve a stable conversion of horizontal power to vertical power, with flexible transmission and low resistance; the counterweight 302 uses its own weight to drive the guide rod 304 to descend smoothly, allowing the suction cup assembly 5 to gently adhere to the workpiece surface; the chain 303 forms a flexible connection, which can adapt to the adsorption of workpieces of different heights and avoid damage to components caused by rigid pulling; the guide rod 304 and the guide support 305 slide in conjunction to limit the lifting path, prevent the suction cup assembly 5 from shaking or deviating during lifting, and ensure accurate separation action.

[0044] In embodiments of the present invention, such as Figure 7 As shown, the switch assembly 6 includes a connecting plate 601 and a contact switch 602. The connecting plate 601 is fixed to the side of the second column 104. The detection end of the contact switch 602 is close to the traction assembly 3 and is used to detect the impact plate 503 in place.

[0045] like Figure 8 , Figure 9 As shown, the separation device also includes a pneumatic power control component 7 and an operating component 8; the pneumatic power control component 7 includes a support plate 701 fixed on the second column 104, and a solenoid valve 702 and a pneumatic control valve 703 are provided on the surface of the support plate 701. The operating component 8 includes a circular tube 801, which is fixed to the second column 104 by a locking block 802. A push switch 803 is provided on the circular tube 801. The push switch 803 is signal connected to the solenoid valve 702 and the pneumatic control valve 703.

[0046] Specifically, the connecting plate 601 is fixed to the side of the second column 104, and the contact switch 602 is fixedly installed on the connecting plate 601. The detection end of the contact switch 602 faces the traction component 3 and is directly opposite the movement path of the impact plate 503, used to detect the raised position of the impact plate 503. In the pneumatic power control component 7, the support plate 701 is fixed at a preset height on the side wall of the second column 104. The surface of the support plate 701 is provided with a solenoid valve 702 and a pneumatic control valve 703 side by side. The two valves stably control the extension and retraction of the cylinder and the vacuum switch, ensuring the smooth operation of the entire pneumatic circuit. The operating component 8 includes a circular tube 801, which is locked and fixed to the operating side of the second column 104 by a locking block 802. A push switch 803 is installed on the tube body of the circular tube 801 to flexibly adapt to the operator's operating height and installation position; manual pressing of the switch can control the cylinder start and stop, suction cup adsorption and release with one button.

[0047] Based on the above embodiments, the specific working process of the automotive sheet stamping separation device provided by the present invention is as follows: When thin stamped parts are stacked, although gaps are reserved between the sheets, they are prone to sticking together and are difficult to separate due to the smoothness of the sheet surfaces and the presence of oil stains. The bracket 1 provides overall fixed support, and the manual pressing operation component 8 sends a control signal. The pneumatic power regulation component 7 controls the on / off of the air circuit and drives the linear cylinder component 2 to operate. The linear cylinder component 2 extends to release the traction component 3, which works with the fixed pulley 4 to complete the power reversal. The traction structure with counterweight relies on gravity to drive the suction cup to descend smoothly, so that the vacuum suction cup adheres to one corner of the surface of the top layer of the stacked thin stamped parts. The pneumatic power regulation component establishes negative pressure, allowing the vacuum suction cup to firmly adhere to the corner of the sheet.

[0048] After the vacuum suction cup completes adsorption, the linear cylinder assembly 2 retracts and pulls the traction group 3 upward, causing the vacuum suction cup to rise vertically with the edge of the sheet metal, lifting one corner of the thin sheet stamping part, so that a sufficient separation gap is quickly formed between the sheet metal layers, completing the separation of a single sheet metal; the suction cup assembly continues to rise and touches the switch assembly 6. After the system determines that the lifting height has reached the standard, it automatically breaks the vacuum, the suction cup releases the workpiece, and two operators can then lift the sheet metal away for transfer and unloading. After the equipment is reset, it waits for the next work cycle.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
