Description

[Technical Field]

[0001] This invention belongs to the field of automated production technology, and in particular relates to a high-temperature demolding automated fixture and demolding method. [Background Technology]

[0002] The production process of normal structural components carries the risk of damage from three sources, especially laptop A / C components. The exterior surface occupies the entire product, and CNC machining often involves processes with a large surface facing downwards. Furthermore, a certain percentage of these components will be damaged during the handling process. To reduce the occurrence of damage during product manufacturing, a protective film is applied to the exterior surface for protection. While most manufacturing plants have implemented automated film application, manual film removal is still used. Manual film removal requires a certain amount of labor costs, and the process itself carries the risk of damage from three sources and product deformation.

[0003] Therefore, some manufacturing plants have proposed using high-temperature adhesive-removing film. This type of protective film can adhere normally to the product at room temperature. When the protective film is immersed in hot water at a temperature of 80°C or higher, it will automatically curl and peel off. Although this solution can avoid product deformation caused by manual film tearing, it still requires manual removal of the peeled protective film from the tray. At this time, workers need to work next to hot water, which is a harsh environment and poses a risk of burns. [Summary of the Invention]

[0004] The purpose of this invention is to provide an automated high-temperature decoction fixture and decoction method, which can realize automated product transfer and automatic removal of the protective film.

[0005] The technical solution of the present invention is as follows: A high-temperature demolding automated clamp is provided for demolding products, wherein the products are placed on a tray, and the clamp includes a machine base, a bracket mounted on the machine base, a clamping mechanism fixed to the bracket, and an adsorption component fixed to the bracket. The machine base is used to drive the bracket to rotate and lift.

[0006] The gripping mechanism includes a first drive assembly fixed to the bracket and two claws respectively connected to opposite sides of the first drive assembly and extending toward the bottom of the bracket. A gripping space is formed between the two claws, and the two claws are used to grab the tray in the gripping space.

[0007] The adsorption assembly includes multiple suction cups fixed to the bracket and extending downward into the gripping space.

[0008] Furthermore, the bottom of the bracket has two spaced-apart movable openings. The first drive assembly includes a bidirectional cylinder fixed between the two movable openings of the bracket, two fixed seats respectively connected to the output end of the bidirectional cylinder and extending from the corresponding movable openings to the bottom of the bracket, and two connecting seats respectively connected to the two fixed seats. The top ends of the two hooks are respectively fixed to the two connecting seats.

[0009] Furthermore, the two hooks are symmetrically arranged, and the bottom edge of the hooks bends and extends toward the grasping space to form at least two hook protrusions arranged at intervals.

[0010] Furthermore, the fixing base includes two spaced clamping plates fixed to the output end of the bidirectional cylinder;

[0011] The connecting seat includes a telescopic plate fixed between the two clamping plates and extending outward from the gripping space, and a reinforcing plate fixed to the bottom side of the clamping plates. One side of the hook, the end of the telescopic plate, and the end of the reinforcing plate are all fixed.

[0012] Furthermore, the gripping mechanism also includes a second drive assembly fixed to the bracket and a clamping seat connected to the second drive assembly. The telescopic plate is provided with a clearance notch. The second drive assembly extends into the gripping space from the clearance notch. The clamping seat is located on the side of the hook near the gripping space. The second drive assembly is used to drive the clamping seat to move in the height direction.

[0013] Furthermore, the second drive assembly includes an adapter plate with one end fixed to the top side of the bracket and the other end bent downwards and extending downwards, and a clamping cylinder fixed to the other end of the adapter plate.

[0014] The clamping seat includes a first clamping block fixed to the output end of the clamping cylinder and a second clamping block assembled on the bottom side of the first clamping block, the second clamping block being made of a soft elastic material.

[0015] Furthermore, the gripping mechanism also includes a clamping component fixed to the side of the claw away from the gripping space, the clamping component being used to clamp against the side of the tray when the claw hooks the tray.

[0016] Furthermore, the clamping assembly includes a positioning block fixed to the claw, a damper assembled to the positioning block, and a stop member connected to the end of the damper. The stop member includes a top block protruding toward the gripping space and two spaced limiting pieces extending toward the top, with the two limiting pieces located on opposite sides of the positioning block.

[0017] Furthermore, connecting pieces are fixed on both opposite sides of the bracket, the bottom end of the connecting piece is bent, and the suction cup is fixed to the bent part at the bottom end of the connecting piece.

[0018] Furthermore, a demolding method is provided, employing the high-temperature automated demolding fixture described in any of the above claims, the demolding method comprising the following steps:

[0019] The bracket is driven to a first preset position, and the two claws of the clamping mechanism clamp the tray containing the product, while the suction cup's suction end abuts against the top surface of the product.

Then, the first drive component drives the two hooks to hook the tray, and the suction cup abuts against the top side of the product on the tray, thereby fixing the product. Afterward, the machine can drive the support to move the tray into the hot water tank. After the product in the tray is soaked until the film and product separate, the machine drives the support to move the tray to the waste film collection area. At this time, the suction cup blows air to blow the film to the waste film collection area. Then, the machine can drive the support to move the product and the tray together to the discharge area. The first drive component drives the hooks to release, so that the product and the tray can be placed together in the discharge area. The high-temperature demolding automated fixture in this solution can realize pallet transfer, product fixation, and air blowing demolding, realizing automated demolding operation, greatly improving production efficiency, reducing labor costs, and ensuring safety and reliability.

Detailed Implementation Methods

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Combination Figure 1-3 A high-temperature demolding automated fixture is provided for demolding a product 20, which is placed on a tray 10. The product 20 can be a shell structure with a large outer surface, such as a laptop A / C component. The high-temperature demolding automated fixture includes a machine base (not shown), a bracket 1 mounted on the machine base, a gripping mechanism 2 fixed to the bracket 1, and an adsorption assembly 3 fixed to the bracket 1. The machine base is used to drive the bracket 1 to rotate and lift. The gripping mechanism 2 includes a first drive assembly 21 fixed to the bracket 1 and two claws 22 respectively connected to opposite sides of the first drive assembly 21 and extending toward the bottom of the bracket 1. The two claws 22 are spaced apart to form a gripping space, and the two claws 22 are used to hook the tray 10 in the gripping space. The adsorption assembly 3 includes multiple suction cups 31 fixed to the bracket 1 and extending toward the bottom into the gripping space.

[0030] In this solution, the machine can drive the support 1 to rotate and lift, thus changing the position of the gripping component and the adsorption component 3. The first drive component 21 can drive the two hooks 22 to perform a hooking action, while the adsorption component 3 can be used to adsorb the film on the product 20. In practical applications, the gripping component can be driven to move to the area where the tray 10 is placed, so that the tray 10 is located in the gripping space. The product 20 that needs to be delaminated is placed in the tray 10. Then, the first drive component 21 drives the two hooks 22 to hook the tray 10, and the suction cup 31 abuts against the top side of the product 20 on the tray 10, thereby fixing the product 20. After that, the machine can drive the support 1 to move the tray 10 into the hot water tank. After the product 20 in the tray 10 is soaked until the film and the product 20 are separated, the machine can drive the support 1 to move the tray 10 to the waste film collection area. At this time, the suction cup 31 blows air to blow the film to the waste film collection area. Then, the machine can drive the support 1 to move the product 20 and the tray 10 together to the discharge area. The first drive component 21 drives the hooks 22 to release, so that the product 20 and the tray 10 can be placed together in the discharge area. The high-temperature demolding automated fixture in this solution can realize the transfer of pallet 10, fixation of product 20, and air blowing demolding, realizing the automated operation of demolding, greatly improving production efficiency, reducing labor costs, and ensuring safety and reliability.

[0031] In this embodiment, the bracket 1 includes a support plate 11, a connector 12 fixed to the middle of the support plate 11, and reinforcing ribs 13 fixed to the top side of the support plate 11 near the two opposite sides. The connector 12 is used to connect with the output end of the machine tool, and the reinforcing ribs 13 are used to improve the overall structural strength of the bracket 1. In this way, the machine tool can drive the bracket 1 to move and rotate in space, which is convenient for adjusting the position of the gripping components.

[0032] It should be understood that the clamping mechanism 2 and the adsorption component 3 together constitute a demolding module. One or more demolding modules can be set on a support 1. When at least two demolding modules are set, each demolding module is preferably evenly arranged around the connector 12. Setting multiple demolding modules can further improve the demolding efficiency of the product 20. In this embodiment, taking two demolding modules symmetrically arranged as an example, such as... Figure 1-2 The left side shows the demolding module that has not hooked onto tray 10, while the right side shows the demolding module that has hooked onto tray 10. It should be understood that in other embodiments, the number and arrangement of demolding modules can be adaptively adjusted according to actual conditions.

[0033] In this application, the structure of one of the demolding modules is further described as an example.

[0034] Furthermore, the bottom of the bracket 1 is provided with two spaced-apart movable openings 111. The first drive assembly 21 includes a bidirectional cylinder 211 fixed between the two movable openings 111 of the bracket 1, two fixed seats 212 respectively connected to the output end of the bidirectional cylinder 211 and extending from the corresponding movable openings 111 to the bottom of the bracket 1, and two connecting seats 213 respectively connected to the two fixed seats 212. The top ends of the two hooks 22 are respectively fixed to the two connecting seats 213. Specifically, the support plate 11 has two spaced movable openings 111. The main body of the bidirectional cylinder 211 is fixed between the two spaced movable openings 111 of the support plate 11. The two output ends of the bidirectional cylinder 211 face the two movable openings 111 respectively. Each output end is fixed with a fixed seat 212. The bottom end of the fixed seat 212 extends from the movable opening 111 into the lower part of the support plate 11. The connecting seat 213 is fixed to the bottom end of the corresponding fixed seat 212. The top end of the hook 22 is fixed to the end of the corresponding fixed seat 212. In this way, the bidirectional cylinder 211 can drive the two fixed seats 212 to move towards each other, thereby realizing the clamping or releasing action of the two hooks 22 moving closer or further away from each other.

[0035] Furthermore, a limiting block 214 is provided near the end of the top side of the bidirectional cylinder 211. The limiting block 214 is used to limit the fixed seat 212 to prevent the two hooks 22 from getting too close and crushing the tray 10.

[0036] In some embodiments, the bidirectional cylinder 211 can also be replaced by a structure of a motor plus a lead screw and slider. For example, the motor is fixed to the support plate 11, the lead screw is arranged along the arrangement direction of the two movable openings 111, the lead screw is driven to rotate by the motor, the threads at both ends of the lead screw have opposite directions and both ends are equipped with sliders, the sliders are slidably mounted on the support plate 11, and then the fixed seat 212 is connected to the sliders. In this way, the gripping action of the two hooks 22 can also be realized. It should be understood that the structure of the first drive assembly 21 can be adapted to the actual situation, as long as the gripping action of the two hooks 22 can be realized.

[0037] Furthermore, the two claws 22 are symmetrically arranged, and the bottom edge of the claws 22 bends and extends toward the grasping space to form at least two hook protrusions 221 arranged at intervals. Specifically, the claws 22 are plate-shaped and have a symmetrical structure. Therefore, each hook protrusion 221 is symmetrically distributed. The edge of the tray 10 is provided with a locking groove 101 corresponding to the hook protrusion 221 of each claw 22. When grasping the tray 10, the position and angle of the bracket 1 are first adjusted so that the hook protrusion 221 and the locking groove 101 are in corresponding positions. Then, the first drive component 21 drives the two claws 22 to move closer together, and the hook protrusion 221 extends into the corresponding locking groove 101. Then, during the upward movement of the claws 22, the hook protrusion 221 can abut against the groove wall of the locking groove 101, and together lift the tray 10.

[0038] Furthermore, the fixed base 212 includes two spaced clamping plates 2121 fixed to the output end of the bidirectional cylinder 211; the connecting base 213 includes a telescopic plate 2131 fixed between the two clamping plates 2121 and extending outwards from the gripping space, and a reinforcing plate 2132 fixed to the bottom side of the clamping plate 2121. One side of the hook 22, the end of the telescopic plate 2131, and the end of the reinforcing plate 2132 are all fixed. By connecting the reinforcing plate 2132 and the telescopic plate 2131, the structure of the connecting base 213 becomes more stable, and the hook 22 becomes more secure. In addition, after the telescopic plate 2131 extends outwards and the hook 22 is fixed at the end, the gripping space formed between the two hooks 22 is larger and is not limited to the size of the bidirectional cylinder 211.

[0039] Furthermore, the gripping mechanism 2 also includes a second drive assembly 23 fixed to the bracket 1 and a clamping seat 24 connected to the second drive assembly 23. The telescopic plate 2131 is provided with a clearance notch 21311. The second drive assembly 23 extends into the gripping space from the clearance notch 21311. The clamping seat 24 is located on the side of the hook 22 near the gripping space. The second drive assembly 23 is used to drive the clamping seat 24 to move in the height direction. The second drive assembly 23 can drive the clamping seat 24 to clamp the pallet 10, making the movement of the pallet 10 more stable.

[0040] Specifically, the second drive assembly 23 includes an adapter plate 231 with one end fixed to the top side of the bracket 1 and the other end bent downwards, and a clamping cylinder 232 fixed to the other end of the adapter plate 231. The adapter plate 231 is L-shaped. The clamping seat 24 includes a first pressing block 241 fixed to the output end of the clamping cylinder 232 and a second pressing block 242 assembled on the bottom side of the first pressing block 241. The second pressing block 242 is made of a soft elastic material, such as rubber or silicone. The adhesive material has a first pressing block 241 in the shape of an inverted T. The first pressing block 241 and each hook protrusion 221 are directly opposite each other. Thus, when the hook claw 22 picks up the tray 10, the first pressing block 241 and the second pressing block 242 can move downward under the drive of the clamping cylinder 232, so that the second pressing block 242 is pressed against the top side of the edge of the tray 10. The second pressing block 242 and the hook protrusion 221 of the corresponding hook claw 22 achieve vertical clamping of the edge of the tray 10, which improves reliability.

[0041] Furthermore, the gripping mechanism 2 also includes a clamping component 25 fixed to the side of the claw 22 away from the gripping space. The clamping component 25 is used to clamp the side of the tray 10 when the claw 22 grips the tray 10. Specifically, the clamping component 25 includes a positioning block 251 fixed to the claw 22, a damper 252 assembled on the positioning block 251, and a pusher 253 connected to the end of the damper 252. The pusher 253 includes a top block 2531 protruding toward the gripping space and two spaced limiting pieces 2532 extending toward the top. The two limiting pieces 2532 are located on opposite sides of the positioning block 251. The limiting pieces 2532 can prevent the pusher 253 from swaying as a whole. The setting of the pusher 253 can achieve abutment against the side of the tray 10, further improving the clamping degree of the side of the tray 10.

[0042] Furthermore, connecting pieces 32 are fixed on both opposite sides of the bracket 1. The bottom end of the connecting piece 32 is bent, and the suction cup 31 is fixed to the bent part at the bottom end of the connecting piece 32. Specifically, two connecting blocks 33 are provided on both opposite sides of the support plate 11. A connecting piece 32 is fixed to each connecting block 33 by screws. Then, the suction cup 31 is vertically fixed to the bent part at the bottom end of the connecting piece 32. The bottom ends of each suction cup 31 are flush. An air pump is connected to the top of the suction cup 31 to realize the suction or blowing of air to the suction cup 31.

[0043] Furthermore, based on the aforementioned high-temperature automated demolding fixture, combined with Figure 4 A method for removing the film is provided, comprising the following steps:

[0044] S100. Drive the bracket 1 to the first preset position. The two claws 22 of the clamping mechanism 2 clamp the tray 10 containing the product 20. The suction end of the suction cup 31 abuts against the top surface of the product 20. Specifically, in this step, the machine can drive the bracket 1 to move and / or rotate so that the two claws 22 of the clamping mechanism 2 reach the tray 10 placement area. One tray 10 is located in the gripping space. Then, the bidirectional cylinder 211 drives the two claws 22 to approach and hook the side of the tray 10. The pressing cylinder 232 drives the first pressing block 241 and the second pressing block 242 to press down and abut against the top side of the edge of the tray 10, thereby clamping the tray 10. It should be understood that at this time, the bottom end of the suction cup 31 just abuts against the top surface of the product 20, that is, the side of the product 20 with the film.

[0045] S200, the drive bracket 1 moves the tray 10 to a hot water tank at a preset temperature for a preset soaking time. The preset temperature is 75-85℃ and the preset time is within 60 seconds. Specifically, if the preset temperature is greater than 80℃, the preset time can be adjusted according to the actual situation, such as 10 seconds, 20 seconds, 30 seconds, 40 seconds, 60 seconds, etc. The machine can move the tray 10 to the hot water tank by moving and / or rotating the bracket 1. After the product 20 in the tray 10 is soaked for the preset time, the film will curl up on its own and lose its adhesive connection with the product 20.

[0046] S300, the drive bracket 1 moves to the second preset position, and the suction cup 31 blows air to separate the detached membrane into the collection area; the second preset position is above the waste membrane collection area. At this time, the bracket 1 can stand up and rotate or shake, and in conjunction with the suction cup 31 blowing air, the rolled membrane and product 20 are separated and fall into the waste membrane collection area.

[0047] S400, the drive bracket 1 moves to the third preset position, and the hooks 22 are released to place the tray 10 on the conveyor belt. Specifically, in this step, during the process of switching the bracket 1 from the second preset position to the third preset position, the bracket 1 is first adjusted to be horizontal to ensure the stability of the tray 10 and the product 20. Then, it moves above the conveyor belt and descends to be close to the conveyor belt. The second drive component 23 drives the clamping seat 24 to release the tray. Then, the first drive component 21 drives the two hooks 22 to release, so that the tray 10 can be placed stably on the conveyor belt.

[0048] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
