Description

Technical Field

[0001] The invention relates to the technical field of metal parts anodizing process production equipment, and in particular to an anodizing hanger, an upper and lower hanging system and a workpiece upper and lower hanging method. Background Art

[0002] Anodized metal casings are widely used in mobile phones, tablets, laptops and other electronic consumer products. Metal casings treated with anodizing can improve corrosion resistance. The oxide film formed by anodizing can effectively protect the metal substrate (usually aluminum or aluminum alloy) from moisture, sweat, oxygen in the air and other chemicals, greatly extending the service life of the casing, and can also enhance the hardness of the surface and improve wear resistance. The oxide film has a high hardness, which can prevent the casing from being worn due to friction, scratches, etc. during daily use, maintain the appearance quality of electronic products, and can improve the surface texture of the metal casing, facilitate dyeing, and improve aesthetics. Anodizing can give the casing a uniform, matte or mirror effect, and can also present a variety of colors through coloring technology, enhancing the visual appeal and brand recognition of the product.

[0003] The production of metal workpieces using anodizing process includes the following steps: unloading, CNC processing, pretreatment (cleaning, sandblasting or brushing), workpiece hanger, anodizing stage, post-treatment (coloring, sealing, cleaning and drying), workpiece hanger, packaging and packaging. The upper and lower hangers of the workpiece are important steps in the anodizing process. In the anodizing stage, the workpiece and the hanger need to be immersed in the anodizing tank together and electricity is applied to accelerate the oxidation of the workpiece surface.

[0004] The metal shell parts of electronic products have folded edges that bend backwards around them, and their cross-section is C-shaped, which is called edging parts in the industry. The outer surface and side surfaces of edging parts such as electronic product shells are both appearance surfaces. The contact points between the hanger and the workpiece will produce contact marks during the anodizing process. For edging parts, the hanger needs to fix the workpiece from its inner non-appearance surface.

[0005] In the anodizing process of general parts, commonly used hangers include disc clamps, frame clamps, etc. This type of hanger has the advantages of easy clamping and firm fixation. However, the workpiece needs to be clamped and fixed from both ends or the outside of the workpiece, so contact marks will be left on the appearance surface of the edging part. Workpieces with high requirements for appearance effects usually cannot use this type of hanger. There are also some, such as needle hangers, which require holes to be punched on the workpiece as hanger fixing points. The hook-type hanger has a low clamping force on the edging part.

[0006] In the prior art, there are also special clamp-type hangers specially designed for edging parts such as electronic product shells. However, this type of hanger is often designed with a complex motion mechanism, including several kinematic pairs. Because in the anodizing process, the hanger and the workpiece are immersed in an oxidation tank with a strong acid and alkali environment, and it is necessary to turn on the power to accelerate the oxidation of the workpiece. The anodizing process is also very corrosive to the hanger itself, which can easily cause the parts of the motion mechanism on the hanger to be oxidized and change their structure, resulting in the failure of the kinematic pairs. In addition, the overly complex design of the hanger will also make it too difficult to put the upper and lower hangers on, and it is impossible to use fully automatic mechanical equipment to carry out the upper and lower hanger operations of the workpiece.

[0017] The rear spring piece is in a rhombus shape, the front and rear ends are respectively the fixed end and the free end of the rear spring piece, and the four sides of the rhombus are the deformation parts of the rear spring piece;

[0018] The fixed end of the side spring piece is fixed on the deformed portion located at the rear of the outer side of the diamond-shaped rear spring piece, or on the deformed portion located at the front of the inner side of the diamond-shaped rear spring piece.

[0026] Applying the upper and lower hanging system proposed above, the present invention also proposes a hanging operation method, which comprises the following steps:

[0027] S11, carrying the empty hanger to the assembly table and fixing it with a locking mechanism, keeping the support assembly facing upward;

[0028] S12, grab and carry the workpiece to the hanging position;

[0029] Waiting hanging position: the workpiece is located directly above the support assembly, the rear folded edge of the workpiece is located directly behind the rear hook, and the front height of the workpiece is higher than the front hook; the workpiece is tilted so that the front height is higher than the rear height;

[0030] S13, driving the workpiece to move forward relative to the hanger, so that the inner side of the rear folded edge of the workpiece abuts against the rear hook; allowing the workpiece to continue to move forward toward the hanger, and the rear spring sheet is compressed and deformed; the deformation of the rear spring sheet drives the free end of the side spring sheet to move outward and abut against the inner side of the side folded edge of the workpiece, until the inner side of the front part of the workpiece moves to the front side of the front hook;

[0031] S14, driving the front side of the workpiece to move downward until the front and rear sides of the workpiece are flush with each other, and the front hook faces the inner side of the front folded edge of the workpiece;

[0032] S15, releasing the workpiece, so that the rear spring sheet pushes the workpiece backwards, and the front hook presses the front folded edge of the workpiece tightly;

[0033] S16, taking the hanger carrying the workpiece away from the assembly table.

[0034] Applying the above-mentioned upper and lower hanging system, the present invention also proposes a lower hanging operation method: comprising:

[0035] Follow these steps:

[0036] S21, carrying the hanger carrying the workpiece to the assembly table and fixing it by a locking mechanism, with the workpiece facing upward;

[0037] S22, fixing the workpiece to be hung;

[0038] S23, driving the workpiece to move forward relative to the hanger until the front hook is separated from the front folded edge of the workpiece;

[0039] S24, lifting the front end of the workpiece upward until the front folded edge of the workpiece is higher than the front hook;

[0040] S25, driving the workpiece to move backward relative to the hanger, so that the rear spring sheet gradually changes from a compressed state to an extended state, and the deformation of the rear spring sheet drives the free end of the side spring sheet and the side hook to move inward and separate from the side folded edge of the workpiece; the workpiece continues to move toward the rear of the workpiece until the rear folded edge of the workpiece separates from the rear spring sheet;

[0041] S26, taking the workpiece away from the hanger.

[0042] A hanger using the above technical solution of the present invention has the following effects:

[0043] In the prior art, a complex motion mechanism needs to be set on the hanger to achieve stable fixing of the workpiece from the inside of the workpiece. The hanger of the present invention abandons the complex motion mechanism and only has a few elastic metal sheets to achieve the same technical effect as the prior art. In addition, the elastic metal sheets do not have complex motion pairs, and the hanger can maintain stable operation for a long time even in a highly corrosive environment.

[0044] The anodizing hanger of the present invention simplifies the steps of the upper and lower hanger operations. It is only necessary to let the rear folded edge of the workpiece press against the rear hook, and the height of the front folded edge is higher than the front hook, and push the workpiece forward. During the compression process of the rear spring sheet, the side hook will be driven to press the folded edge of the side of the workpiece outward until the front folded edge of the workpiece moves to the front of the front hook, and the front of the workpiece naturally falls, and then the workpiece can be released. The rear spring sheet will partially rebound, allowing the front hook to press against the front folded edge of the workpiece. The entire loading process requires three steps, aligning, pushing the workpiece up, and finally the front falling down. The lowering process is similar. First, push the workpiece upward, so that the front folded edge of the workpiece is separated from the front hook, and then lift the front of the workpiece. Finally, the workpiece moves backward to separate from the hanger.

[0045] In order to complete the upper and lower hanger operations, the present invention also proposes an upper and lower hanger system. Due to the innovative design of the hanger of the present invention, the system does not need to set a driving component to drive the side springs and rear springs on the hanger. It only needs to fix the hanger on the assembly table and then operate the workpiece to move to complete the upper and lower hanger operations.

[0046] The accompanying invention also provides specific action steps for the upper and lower hanging systems when performing upper hanging operations and lower hanging operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The specific embodiments of the present invention are described in detail below. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0062] In the present invention, unless otherwise specified, the directional words "front, back, left, right" are used as shown in the figure. Figure 2 As shown, the position close to the top of the hanger 1 is "front" and the position close to the tail of the hanger 1 is "rear"; the two sides of the hanger 1 are "left" and "right" respectively. During the anodizing process, the hanger 1 is hung on the target, at which time the front hook 1a1 on the hanger 1 is on the top and the rear hook 1b2 is on the bottom. For the convenience of expression, this article uniformly adopts the level of assembly process Figure 2 Describe the positional relationship in .

[0063] The first aspect of the present invention provides a hanger 1, comprising a frame 1d and a plurality of support components mounted on the frame 1d. The support components include a front support mechanism 1a, a rear support mechanism 1b, and a side support mechanism 1c for supporting the front, rear, left and right sides of a workpiece 2 respectively.

[0064] The front supporting mechanism 1a includes a plurality of front hooks 1a1 , which are fixed on the frame 1d , and the front hooks 1a1 hook the inner side of the front folded edge 2c of the workpiece 2 .

[0065] The rear support mechanism 1b includes a rear spring piece 1b1 and a rear hook 1b2, wherein the fixed end of the rear spring piece 1b1 is fixed to the frame 1d, and the free end is provided with the rear hook 1b2. The rear hook 1b2 can hook the inner side of the rear folded edge 2c of the workpiece 2.

[0066] The side support mechanism 1c is provided with two left and right sides to respectively support the left and right sides of the workpiece 2, and the side support mechanism 1c includes a side spring sheet 1c1 and a side hook 1c2, the fixed end of the side spring sheet 1c1 is fixed to the rear spring sheet 1b1, and the free end is installed with the side hook 1c2. The rear hook 1b2 can support the inner side of the rear folded edge 2c of the workpiece 2.

[0067] The rear spring sheet 1b1 has a compressed state and an extended state. When the rear spring sheet 1b1 is compressed / extended, it drives the free end of the side spring sheet 1c1 to move. When the rear spring sheet 1b1 is in the compressed state, the free end of the side spring sheet 1c1 moves outward. When the rear spring sheet 1b1 is in the extended state, the free end of the side spring sheet 1c1 moves inward.

[0068] Skeleton 1d:

[0069] The hanger 1 includes a frame 1d and a plurality of support components arranged on the frame 1d. The support components are used to fix the workpiece 2. The support components include a front support mechanism 1a supporting the front of the workpiece 2, a rear support mechanism 1b supporting the rear of the workpiece 2, and a side support mechanism 1c supporting the left and right sides of the workpiece 2.

[0070] Since the working environment of the hanger 1 is very corrosive, the entire hanger 1 is made of titanium alloy. Since the movable parts and kinematic pairs are easily deformed and failed after being corroded, the support components of the hanger 1 of the present invention are directly fixed on the frame 1d.

[0071] like Figure 4 and Figure 5 As shown in the figure, the skeleton 1d of the hanger 1 is a whole frame structure, and the skeleton 1d mainly includes a keel, a main hook, a locking mechanism 4a and a power connection plate. The keel is the main body of the skeleton 1d, and other auxiliary structures are fixed on the keel. The left and right keels run through the entire hanger 1. The top of the hanger 1 is provided with a main hook, and the main hook at the top hangs the hanger 1 on the target. A power connection plate is set on the main hook. When the anodizing operation is performed, the target will be energized, and the current will be conducted to the entire skeleton 1d through the power connection plate, and then conducted to the workpiece 2. The hanger 1 is provided with a locking mechanism 4a that cooperates with the locking mechanism 4a at the top and bottom. The locking mechanism 4a fixes the hanger 1 through the locking mechanism 4a parts.

[0072] The present invention uses the front support mechanism 1a, the rear support mechanism 1b and the side support mechanism 1c to support the workpiece 2 from four sides of the workpiece 2, thereby ensuring that the workpiece 2 will not fall off the hanger 1 when moving in the anodizing tank or being sprayed with water.

[0073] Front support mechanism 1a:

[0074] The front support mechanism 1a is used to support the workpiece 2 from the front part, and is the core component that bears the stress of the workpiece 2. Therefore, the front support mechanism 1a includes a plurality of front hooks 1a1, and the front hooks 1a1 can hook the inner side of the front folded edge 2c of the workpiece 2. A plurality of front hooks 1a1 can be arranged at intervals along the extension direction of the upper edge of the workpiece 2. The front hooks 1a1 are directly fixed on the frame 1d.

[0075] Rear support mechanism 1b:

[0076] The rear support mechanism 1b supports the workpiece 2 from the rear of the workpiece 2. Figure 5 As shown in the figure, the rear support mechanism 1b includes a rear spring piece 1b1 and a rear hook 1b2. In the figure, the rear spring piece 1b1 on the side where the workpiece 2 is installed is in a compressed state, and the rear spring piece 1b1 on the side where the workpiece 2 is not installed is in an extended state. The rear spring piece 1b1 is an elastic member, and its material is titanium alloy. The front end of the rear spring piece 1b1 is a fixed end. The fixed end is directly fixed to the skeleton 1d. The rear end of the rear spring piece 1b1 is a free end, and the free end is connected to the rear hook 1b2. The rear spring piece 1b1 can be elastically deformed in the front-to-back direction. When the rear spring piece 1b1 is in a compressed state, a downward supporting force will be applied to the rear spring piece 1b1. When the rear spring piece 1b1 is deformed, the rear hook 1b2 can move in the front-to-back direction to complete the action of inserting into the inner side of the folded edge 2c of the lower edge of the workpiece 2 or the action of detaching from the workpiece 2.

[0077] The weight of the metal shell of electronic consumer products is usually not more than 1kg, and the hanger 1 generally requires a force of about 20N to 50N to fix the workpiece 2. When the hanger 1 is in working condition, the elastic force of the rear spring sheet 1b1 pushes the workpiece 2 downward through the rear hook 1b2, and the front hook 1a1 supports the workpiece 2 upward. The force acting on the front hook 1a1 is the sum of the weight of the workpiece 2 and the elastic force of the rear spring sheet 1b1. The front hook 1a1 is designed as a fixed hook to improve the stability of the workpiece 2 during movement. The fixed front hook 1a1 is on the top, and the rear hook 1b2 set by the elastic sheet is on the bottom to increase the supporting force of the front hook 1a1 and reduce the supporting force of the rear hook 1b2.

[0078] Side support mechanism 1c:

[0079] The side support mechanism 1c stabilizes the workpiece 2 from the left and right sides of the workpiece 2 to prevent the workpiece 2 from sliding left and right. The side support mechanism 1c is subjected to less force and only serves to stabilize the workpiece 2. The elastic coefficient of the side spring sheet 1c2 is smaller than that of the rear spring sheet 1b1. The side hook 1c2 includes a side spring sheet 1c1 and a side hook 1c2. The fixed end of the side spring sheet 1c1 is fixed to the rear spring sheet 1b1, and the free end is connected to the side hook 1c2. The side hook 1c2 can hook the inner side of the folded edge 2c on the left and right sides of the workpiece 2, and the side spring sheet 1c1 supports the side hook 1c2 outward. The side support mechanism 1c is provided with two left and right sides, which support the workpiece 2 from both sides of the workpiece 2 respectively. When the workpiece 2 slides in the left and right directions, the left and right side support mechanisms 1c are subjected to unbalanced forces, and the two side support mechanisms 1c will support the workpiece 2 to return to its original position.

[0080] In the present invention, the side support mechanism 1c is a driven member, and the side spring sheet 1c1 is fixed on the rear spring sheet 1b1. When the rear spring sheet 1b1 is deformed by force, it will drive the side spring sheet 1c1 to move, and then drive the side hook 1c2 at the free end of the side spring sheet 1c1 to move. Specifically, the rear spring sheet 1b1 has a compressed state and an extended state, and the rear spring sheet 1b1 drives the free end of the side spring sheet 1c1 to move when it is compressed / extended. When the rear spring sheet 1b1 is in a compressed state, the free end of the side spring sheet 1c1 moves outward; when the rear spring sheet 1b1 is in an extended state, the free end of the side spring sheet 1c1 moves inward.

[0081] In summary, the hanger 1 fixes the workpiece 2 by means of the front hook 1a1, the rear hook 1b2 and the side hook 1c2. The front hook 1a1, the rear hook 1b2 and the side hook 1c2 are inserted into the inner side of the folded edge 2c of the workpiece 2. Figure 7 As shown in , usually a workpiece 2 such as a mobile phone or a laptop computer shell has a groove at the edge fold 2c, and the front hook 1a1, the rear hook 1b2 and the side hook 1c2 are inserted into this groove. If the workpiece 2 does not have a groove at the corresponding position of the aforementioned hook, it is necessary to adjust the position of the hook. If there is no groove for the workpiece 2 to be inserted into the upper edge or the lower edge of the workpiece 2, then it is necessary to modify the design of the workpiece 2, and reserve a groove in advance at the corresponding position of the front hook 1a1 and the rear hook 1b2. If there is no groove for the workpiece 2 to be inserted into on the side edges on the left and right sides of the workpiece 5, it is not necessary to add a groove on the side of the workpiece 5, and the side hook 1c2 can be directly supported against the inner side of the fold 2c.

[0082] As to how the rear spring piece 1b1 drives the side spring piece 1c1, the present invention proposes two design ideas.

[0083] (1) The middle part of the rear spring sheet 1b1 includes a plurality of continuous deformation parts, and the two ends of the rear spring sheet 1b1 are respectively a fixed end and a free end. During the elastic deformation process of the rear spring sheet 1b1, any deformation part rotates. The side spring sheet 1c1 is fixed on the deformation part that rotates. When the rear spring sheet 1b1 is compressed, the free end of the side spring sheet 1c1 moves outward to support the inner side of the side folding edge 2c of the workpiece 2. The part of the rear spring sheet 1b1 where the side spring sheet 1c1 is fixed rotates during the elastic deformation process, which can drive the side spring sheet 1c1 fixed thereon to rotate, and the free end of the side spring sheet 1c1 can drive the side hook 1c2 to rotate within a circular arc. The left and right components of the circular motion of the side spring sheet 1c1 will drive the side spring sheet 1c1 to push outward to press the workpiece 2 or move inward to separate from the workpiece 2.

[0084] (2) The middle part of the rear spring sheet 1b1 includes a plurality of continuous deformation parts, and the two ends of the rear spring sheet are respectively a fixed end and a free end. During the elastic deformation process of the rear spring sheet 1b1, any deformation part moves horizontally in the left and right directions. The side spring sheet 1c1 is fixed on the deformation part that moves horizontally. When the rear spring sheet 1b1 moves in compression, the free end of the side spring sheet 1c1 moves outward to support the inner side of the side fold 2c of the workpiece 2.

[0085] The second design idea is to utilize the left-right lateral movement of a specific part of the rear spring sheet 1b1 during the elastic deformation process, and utilize the left-right lateral movement to directly drive the side spring sheet 1c1 to drive the side hook 1c2 to move left-right. Specifically, when the rear spring sheet 1b1 is compressed and deformed, the side spring sheet 1c1 drives the side hook 1c2 to move outward; when the rear spring sheet 1b1 rebounds, the side spring sheet 1c1 drives the side hook 1c2 to move inward. "Left-right lateral movement" refers to: the movement of the deformation part of the fixed side spring sheet 1c1 during the elastic deformation process, and the movement components in the left-right direction are decomposed through movement decomposition. That is, the specific part of the rear spring sheet 1b1 of the fixed side spring sheet 1c1 can move up and down slightly during elastic deformation, and the small up and down movement will not affect the support of the side spring sheet 1c1 on the workpiece 2, nor will it cause the side spring sheet 1c1 to separate from the side of the workpiece 2.

[0086] The present invention Figure 4 and Figure 5 The solution provided in the embodiment is a fusion of the two solutions of the rear spring sheet 1b1 driving the side spring sheet 1c1 described above. When the rear spring sheet 1b1 is deformed, the specific position of the fixed rear spring sheet 1b1 is rotated and also moves horizontally in the left and right directions. Specifically, the rear support mechanism 1b is provided with two left and right sides, the left side support mechanism 1c is provided on the rear support mechanism 1b on the same side, and the right side support mechanism 1c is provided on the rear support mechanism 1b on the same side.

[0087] like Figure 5As shown, the rear spring piece 1b1 is in a rhombus shape, the front and rear ends of the rhombus are respectively a fixed end and a free end of the rear spring piece 1b1, and the four sides of the rhombus are deformation parts of the rear spring piece 1b1.

[0088] The fixed end of the side spring piece 1c1 is fixed to the deformation part of the diamond-shaped rear spring piece located at the outer rear side, or the fixed end of the side spring piece 1c1 fixes the deformation part of the diamond-shaped rear spring piece located at the inner front side.

[0089] like Figure 4 As shown in , the support components respectively arranged on the front and back sides of the frame are defined as a group; multiple groups of support components are distributed at intervals along the extension direction of the frame.

[0090] Upper and lower hanger 1 system:

[0091] The present invention uses the hanger 1 provided above and further proposes an upper and lower hanger system for hanging the workpiece 2 on the hanger 1 or hanging the workpiece 2 from the hanger 1 .

[0092] Specifically, the upper and lower hanger system includes a hanger 1, an assembly table 3, a workpiece manipulator 5 and a hanger manipulator 6. The hanger 1 is the hanger 1 provided by the present invention. A locking mechanism 4a is provided on the assembly table 3 for fixing the hanger 1. The workpiece manipulator 5 is used to load the workpiece 2 onto the assembly table 3 or unload the workpiece 2 from the assembly table 3. The hanger manipulator 6 is used to load the hanger 1 onto the assembly table 3 or unload the hanger 1 from the assembly table 3.

[0093] The assembly table 3 includes a frame, and a combination station is provided on the table of the frame, and a locking mechanism 4a is provided at the combination station. The locking mechanism 4a can fix the hanger 1 to the combination station. Figure 1 and Figure 2 As shown, the frame is a workbench, and a combination station is reserved in the middle of the upper surface of the frame, and the subsequent work of hanging the workpiece 2 up and down is carried out at the combination station. A locking mechanism 4a is installed at the combination station, and the locking mechanism 4a cooperates with the locking mechanism 4a on the aforementioned hanger 1 to fix the hanger 1 to the assembly table 2.

[0094] Here are some design examples of the locking assembly 2c3 and the locking mechanism 4a:

[0095] 1. The locking component is a cylinder / hydraulic cylinder, and the execution end of the cylinder / hydraulic cylinder has a conical positioning cone. The locking mechanism 4a is a positioning hole that cooperates with the positioning cone. The positioning cone is inserted into the positioning hole to position and fix the hanger 1 to the assembly table 3.

[0096] 2. The locking mechanism 4a includes a trumpet-shaped slot that is larger at the top and smaller at the bottom and a pressing structure. The locking mechanism 4a includes a positioning block that cooperates with the slot. The positioning block enters the slot and is pressed by the pressing structure.

[0097] In the present invention, the side support mechanism 1c of the hanger 1 is a follow-up design, and moves with the deformation of the rear spring sheet 1b1. There is no need to set a complex driver on the assembly table 3 to drive the side spring sheet 1c1 and the rear spring sheet 1b1, which greatly simplifies the design of the assembly table 3. However, when the workpiece 2 is placed on or off the hanger, the workpiece 2 can move forward and backward relative to the hanger 1 to complete the operation of the upper and lower hangers 1.

[0098] When the workpiece 2 is on and off the hanger 1, there are two ways to achieve the forward and backward movement of the workpiece 2 relative to the hanger 1:

[0099] 1. The hanger 1 remains stationary, and the workpiece manipulator 5 carries the workpiece 2 forward.

[0100] 2. The workpiece 2 is stationary, and the hanger 1 moves forward and backward. Specifically, a translation driver is provided on the assembly table 3, and the translation driver drives the locking mechanism 4a and the hanger 1 fixed thereto to move forward and backward.

[0101] like Figure 3 As shown, a flip assembly 4 is arranged on the assembly table 3, and the flip assembly 4 includes a flip bracket, a translation bracket, a flip driver, a translation driver and a locking mechanism 4a.

A translation guide rail is arranged along the extension direction of the flip bracket, and the translation bracket is slidably arranged on the translation guide rail. A translation driver is arranged between the translation bracket and the flip bracket, and the translation driver drives the translation bracket to slide back and forth on the flip bracket. The locking mechanism 4a is installed on the translation bracket.

[0103] Workpiece manipulator 5:

[0104] like Figure 1 As shown in , the workpiece manipulator 5 can be selected as an industrial robot, and multiple robots can be set to speed up the loading and unloading speed, and is used to load the workpiece 5 from the pick-and-place station 6 of the workpiece 2 to the assembly table 2, or to unload the workpiece 5 from the assembly table 2 to the pick-and-place station 6 of the workpiece 2. The execution end of the hanger manipulator 4 is equipped with a hanger 1 clamping tool. The hanger manipulator 4 transfers the empty hanger 1 to the assembly station 2d, and takes the full hanger 1 away from the assembly station 2d. The clamping tool of the hanger manipulator 4 is a clamp-shaped clamp, which directly clamps the upper and lower ends of the hanger 1. The main body of the hanger 1 is made of titanium alloy, and its strength is sufficient to meet the requirements.

[0105] Hanger robot 6:

[0106] like Figure 1As shown in , the hanger manipulator 6 is an industrial robot, and multiple hangers can be provided to speed up the loading and unloading speed. The hanger manipulator 6 is used to load the hanger 1 from the hanger 1 to the assembly table 3; or to unload the hanger 1 from the assembly table 3 to the tool loading and unloading station.

[0107] The execution end of the workpiece manipulator 5 is provided with a clamping fixture for the workpiece 2. The clamping fixture for the workpiece 2 is usually a suction cup fixture to avoid scratching the appearance surface 2a of the workpiece 2. The workpiece manipulator 5 is divided into a workpiece loading manipulator and a workpiece unloading manipulator.

[0108] Artifact 2:

[0109] like Figure 6 and Figure 7 As shown, the workpiece 2 targeted by the present invention is a workpiece 2 such as an edge-wrapped part, such as a housing of a mobile phone, a tablet computer, or a laptop computer.
