Description

Technical Field

[0001] This utility model belongs to the field of semiconductor packaging and testing, and in particular relates to a film-tearing gripper mechanism with high clamping force. Background Technology

[0002] In the back-end processes of semiconductor packaging and testing, after the chip is attached to the lead frame, a high-temperature resistant film needs to be applied to the back of the lead frame. This scenario is illustrated in the instruction manual. Figure 1-2 As shown, the chip on the front of the lead frame can then be encapsulated. After encapsulation, a substrate with a film on the back and a plastic cover on the front is formed. Before proceeding to the next process, the film on the back of the substrate is removed.

[0003] To address the aforementioned need for substrate film removal, the industry currently typically uses manual labor or specialized film-removing equipment to peel off the film on the back of the substrate. However, when manually removing the film, the high-temperature resistant film is not heated, making it difficult to peel off, resulting in low efficiency and potential damage to the substrate. Furthermore, the film may have strong adhesion and be firmly attached, making it difficult to completely remove the entire film using conventional film-removing equipment due to insufficient clamping force. Therefore, to address these issues, this technical solution proposes a high-force film-removing gripper mechanism. Utility Model Content

[0004] This invention provides a high-force film-tearing gripper mechanism that can handle substrates with film on the back and notched edges, as well as other special film-tearing needs. The mechanism is equipped with two sets of film-tearing grippers. One set employs a unique pneumatic linkage mechanism, with the upper and lower grippers making line contact to effectively clamp the film, resulting in a clamping force far greater than ordinary film-tearing grippers. The other set is a secondary auxiliary film-tearing gripper; the two sets of grippers clamp the film sequentially, performing the tearing action together. This solves the problems of difficulty in tearing films with high adhesion and low tearing efficiency. In summary, it solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a high-force film-tearing gripper mechanism, which includes a primary film-tearing gripper assembly, a secondary film-tearing gripper assembly, a waste film residue detection assembly, and a film-tearing gripper mounting base assembly; the primary film-tearing gripper assembly and the secondary film-tearing gripper assembly are mounted on the film-tearing connecting rod assembly mounting plate.

[0007] The film-tearing clamp assembly includes an upper clamping jaw of the film-tearing clamp driven by a cylinder through a linkage mechanism, a lower clamping jaw of the film-tearing clamp that cooperates with the upper clamping jaw to perform film-tearing work, a film-tearing linkage driving cylinder for driving the linkage mechanism to realize the rotation of the upper clamping jaw of the film-tearing clamp, and a film-tearing linkage cylinder fixing constraint for fixing the entire upper clamping jaw pneumatic linkage mechanism to the film-tearing linkage assembly mounting plate.

[0008] The secondary film-tearing clamp assembly includes an upper secondary film-tearing clamp, a lower secondary film-tearing clamp that works in conjunction with the upper secondary film-tearing clamp, a film-tearing clamp cylinder that drives the lower secondary film-tearing clamp and the upper secondary film-tearing clamp to open and close, a secondary clamp lifting cylinder that drives the secondary film-tearing clamp to lift and lower, and a secondary clamping cylinder mounting base for fixing the secondary film-tearing clamp on a first linear guide slider and moving along the first linear guide slider together with the first linear guide.

[0009] The waste film residue detection assembly includes a membrane residue detection fiber mounting base for mounting and fixing the membrane residue detection fiber and a first tearing arm base for fixing and constraining; the membrane residue detection fiber mounting base is provided with a downward air blowing hole.

[0010] The film-tear clamp mounting base assembly includes a second film-tear arm base and a film-tear arm angle adjustment block for fixing; a film-tear arm Z-direction resistance slider fixed to the second linear guide slider and provided with downward pulling force by a side tension spring; a film-tear arm angle adjustment block fixed to the film-tear arm Z-direction resistance slider and adjusted by set screws around the perimeter to adjust the installation angle of the film-tear arm; an optical fiber amplifier for displaying optical fiber detection signals; a resistance sensor mounting base for mounting and fixing a Z-direction resistance alarm photoelectric sensor; a first signal flag for providing an X-direction resistance alarm signal; a film-tear arm X-direction resistance slider fixed to the second linear guide and provided with leftward pulling force by an X-direction tension spring; a second linear guide for guiding the film-tear arm X-direction resistance slider; a photoelectric sensor for detecting the Z-direction resistance alarm signal; a second signal flag for providing the Z-direction resistance alarm signal; a third linear guide for guiding the Z-direction resistance movement of the film-tear arm; and an X-direction resistance limiting block for limiting the Z-direction resistance movement of the film-tear arm.

[0011] Furthermore, the upper jaw of the connecting rod tearing clamp rotates through the connecting rod jaw rotating pin, and the connecting rod jaw rotating pin is constrained by the upper jaw fixing constraint. The tearing connecting rod drive cylinder is connected to the connecting rod jaw rotating pin through the piston end elbow of the tearing connecting rod cylinder.

[0012] Furthermore, the film-tearing connecting rod cylinder fixing constraint is fixed with an equal-height bolt for flexible swinging when the film-tearing connecting rod drive cylinder is working. The film-tearing connecting rod drive cylinder is fixed through the non-piston end elbow joint of the film-tearing connecting rod cylinder, so that the film-tearing connecting rod drive cylinder can flexibly swing around the equal-height bolt when it moves.

[0013] Furthermore, the secondary film-tearing clamp cylinder is fixed by a cylinder mounting base, and the first linear guide rail guides the lifting and lowering movement of the secondary film-tearing clamp.

[0014] Furthermore, the X-direction tension spring is mounted and fixed on the tension spring mounting base.

[0015] Furthermore, the second signal flag is fixed to the Z-axis resistance slider of the film-tearing arm via a signal flag mounting seat.

[0016] The present invention has the following advantages over the prior art:

[0017] (1) The high-force film-tearing claw mechanism of this solution mainly serves substrates with film on the back and notches on the frame, and can also serve the film-tearing needs in other special cases; the high-force film-tearing claw mechanism is equipped with two sets of film-tearing claws, one of which is a unique pneumatic linkage mechanism. The upper and lower claws are in line contact, which can clamp the film well. The film-tearing claw has a much greater clamping force than ordinary pneumatic film-tearing claws; a secondary auxiliary film-tearing claw is also provided. The two sets of claws clamp the film in front and behind sequence and perform the film-tearing action together, which can solve the problem of film-tearing with high adhesion.

[0018] (2) The large clamping force tearing claw mechanism has a compact structure. Compared with traditional manual tearing or tearing with consumables, it is equipped with tearing resistance alarm function and fiber optic for detecting waste film residue at the claw position, which avoids damage to the substrate when tearing the film.

[0019] (3) The mechanism occupies little space and the film-tearing action is simple. This film-tearing gripper mechanism can be matched with different types of substrate film-tearing equipment.

[0020] (4) The device is also equipped with an air blowing function to prevent waste film from sticking to the grippers and to assist in the collection of waste film generated by tearing the film.

[0021] (5) The mechanism is also quite compatible. For substrates with different widths and notches on the edges that are common in the industry, the film peeling work can be carried out by adjusting the installation position of the clamps.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "side", "left", "opening and closing movement", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] like Figure 1 The image shown is a schematic diagram of a substrate with a notched frame and a film attached to the back. Figure 2 Based on Figure 1 Based on this, a schematic diagram of a substrate with a notched edge after the film has been removed is shown. In existing technologies, when manually tearing the film, these high-temperature resistant films are not heated, making them very difficult to remove. This results in low tearing efficiency and may damage the substrate, causing losses. Furthermore, in this process, there is a type of film with very strong adhesion that adheres firmly. When using film-tearing equipment to tear this type of film, the clamping force of ordinary film-tearing clamps is insufficient, failing to completely remove the entire film. Therefore, this technical solution proposes a high-force film-tearing gripper mechanism.

[0036] Please see Figure 3-7 As shown, this utility model provides a high-force film-tearing gripper mechanism, comprising a primary film-tearing gripper assembly 1, a secondary film-tearing gripper assembly 2, a waste film residue detection assembly 3, and a film-tearing gripper mounting base assembly 4; the primary film-tearing gripper assembly 1 and the secondary film-tearing gripper assembly 2 are mounted on the film-tearing connecting rod assembly mounting plate 112.

[0037] like Figure 4 As shown, the film-tearing clamp assembly 1 includes an upper clamping jaw 101 driven by a cylinder through a linkage mechanism, a lower clamping jaw 103 that cooperates with the upper clamping jaw to perform film-tearing work, a film-tearing linkage drive cylinder 106 for driving the linkage mechanism to realize the rotation of the upper clamping jaw 101, and a film-tearing linkage cylinder fixing constraint 110 that fixes the entire upper clamping jaw pneumatic linkage mechanism to the film-tearing linkage assembly mounting plate 112.

[0038] The upper gripper 101 of the linkage film-tearing clamp is driven by a cylinder through a linkage mechanism, and cooperates with the lower gripper 103 of the linkage film-tearing clamp to form a primary film-tearing clamp. The upper and lower grippers perform film-tearing operations through line contact. The lower gripper 103 of the linkage film-tearing clamp serves as the fixed lower gripper of the primary film-tearing clamp, and cooperates with the linkage-driven upper gripper to perform film-tearing operations. The upper gripper 101 of the linkage film-tearing clamp rotates via a linkage gripper rotating pin 102, which is constrained by the upper gripper fixing constraint 104. The film-tearing linkage drive... The moving cylinder 106 and the rotating pin 102 of the connecting rod gripper are connected through the piston end elbow 105 of the film-tearing connecting rod cylinder; the first air pipe connector 107 is used to connect the air supply pipe and the cylinder; the non-piston end elbow 108 of the film-tearing connecting rod cylinder is used to fix the film-tearing connecting rod drive cylinder, so that it can flexibly swing around the equal height bolt when it moves; the film-tearing connecting rod assembly upright plate reinforcing rib 111 is used to reinforce the connection and fixation between the lower gripper and the film-tearing connecting rod assembly mounting upright plate; the film-tearing connecting rod assembly mounting upright plate 112 is used to install and fix the primary film-tearing clamp connecting rod assembly and the secondary film-tearing clamp assembly;

[0039] like Figure 5As shown, the secondary film-tearing clamp assembly 2 includes an upper secondary film-tearing clamp 201, a lower secondary film-tearing clamp 202 that works in conjunction with the upper secondary film-tearing clamp 201, a film-tearing clamp cylinder 203 that drives the lower secondary film-tearing clamp 202 and the upper secondary film-tearing clamp 201 to perform opening and closing movements, a secondary clamp lifting cylinder 207 that drives the secondary film-tearing clamp to perform lifting movements, and a secondary clamp cylinder mounting base 209 for fixing the secondary film-tearing clamp cylinder 203 to a first linear guide rail slider 211 on a first linear guide rail 210 and moving along the first linear guide rail 210 together with the first linear guide rail slider 211. The upper secondary film-tearing clamp 201 is driven by the opening and closing cylinder and works in conjunction with the lower secondary film-tearing clamp. After the primary film-tearing clamp assembly tears a portion of the film, it clamps the film again, and the two sets of clamps work together to perform subsequent film-tearing actions. This helps reduce the chance of the film detaching from the grippers during subsequent film-tearing movements. The lower gripper 202 of the secondary film-tearing clamp is driven by an opening and closing cylinder and works in conjunction with the upper gripper of the secondary film-tearing clamp. After the primary film-tearing clamp assembly tears a portion of the film, it clamps the film again, and the two sets of grippers perform the subsequent film-tearing action together, which helps reduce the chance of the film detaching from the grippers during subsequent film-tearing movements. The film-tearing clamp cylinder 203 is used to drive the upper and lower grippers of the secondary film-tearing clamp to perform opening and closing movements.

The secondary clamp cylinder mounting base 209 is used to fix and constrain the secondary film-tearing clamp cylinder on the linear guide slider, so that it can move along the linear guide with the slider.

[0040] like Figure 6 As shown, the waste film residue detection assembly 3 includes a film residue detection fiber mounting base 302 for mounting and fixing the film residue detection fiber 301, and a first film tearing arm base 304 for fixing and constraining; the film residue detection fiber mounting base 302 is equipped with a downward air blowing hole; the film residue detection fiber 301 is equipped with two sets of waste film detection fibers to detect whether there is any waste film residue on the film tearing claw after the film is torn off; the film residue detection fiber mounting base 302 is used to mount and fix the film residue detection fiber, and the mounting base is also equipped with a downward air blowing hole, which can blow the waste film downward after the film is torn off, so as to prevent the waste film from sticking to the claw; the fourth air pipe connector 303 connects the air supply pipe and the air blowing hole; the film tearing arm base 304 is used to fix and constrain the primary film tearing clamp assembly, the secondary film tearing clamp assembly, and the waste film residue detection assembly;

[0041] like Figure 7As shown, the film-tear clamp mounting base assembly 4 includes a second film-tear arm base 401 and a film-tear arm angle adjustment block 402 for fixing; a film-tear arm Z-axis resistance slider 403 fixed to the second linear guide slider 417 and provided with downward pulling force by a tension spring on the side; a film-tear arm angle adjustment block 402 fixed to the film-tear arm Z-axis resistance slider 403 and adjusted by set screws around the perimeter; an optical fiber amplifier 404 for displaying optical fiber detection signals; a resistance sensor mounting base 405 for mounting and fixing a Z-axis resistance alarm photoelectric sensor; and a lifting... The system includes a first signal flag 406 for providing an X-axis resistance alarm signal, an X-axis resistance slider 410 for the film-tearing arm fixed on a second linear guide rail 411 and provided with a leftward pulling force by an X-axis tension spring 409, a second linear guide rail 411 for guiding the X-axis resistance slider 410 for the film-tearing arm, a photoelectric sensor 412 for detecting a Z-axis resistance alarm signal, a second signal flag 413 for providing a Z-axis resistance alarm signal, a third linear guide rail 414 for guiding the Z-axis resistance movement of the film-tearing arm, and an X-axis resistance limiting block 415 for limiting the Z-axis resistance movement of the film-tearing arm.

[0042] The film-tearing arm base 401 is used to fix and constrain the primary film-tearing clamp assembly, the secondary film-tearing clamp assembly, and the waste film residue detection assembly, which are fixed to the film-tearing arm angle adjustment block by themselves; the film-tearing arm angle adjustment block 402 is used to fix the film-tearing arm Z-direction resistance slider, and the installation angle of the film-tearing arm can be adjusted by the set screws around it; the film-tearing arm Z-direction resistance slider 403 is used to fix the film-tearing arm Z-direction resistance slider, and a downward pulling force is provided by the side tension spring. When the film-tearing arm encounters resistance in the Z-direction downward movement, the Z-direction resistance slider can move along the linear guide rail; the film-tearing arm X-direction resistance slider 410 is fixed to the linear guide rail slider, and a leftward pulling force is provided by the side tension spring. When the film-tearing arm encounters greater resistance in the X-direction when tearing the film, the X-direction resistance slider can move along the linear guide rail, thereby triggering a resistance alarm to prevent damage to the film-tearing product; the cable tie 418 is used to fix and constrain the air tube and cable; the adapter plate 419 is used to connect the cable of the film-tearing clamp assembly;

[0043] Among them, the film-tearing connecting rod cylinder fixing constraint 110 is fixed with a height-equalizing bolt 109 for flexible swinging when the film-tearing connecting rod drive cylinder 106 is working. The film-tearing connecting rod drive cylinder 106 is fixed by the non-piston end elbow 108 of the film-tearing connecting rod cylinder, so that the film-tearing connecting rod drive cylinder 106 swings flexibly around the height-equalizing bolt 109 when it moves. The secondary film-tearing clamp cylinder 203 is fixed by the cylinder mounting seat 206. The first linear guide rail 210 guides the lifting and lowering movement of the secondary film-tearing clamp. The X-direction tension spring 409 is installed and fixed on the tension spring mounting seat 407. The second signal flag 413 is fixed on the Z-direction resistance slider 403 of the film-tearing arm by the signal flag mounting seat (416).

[0044] The working principle of this organization is as follows:

[0045] Step 1: The film-tearing gripper mechanism moves to the designated film-tearing and clamping position on the equipment to prepare for film clamping.

[0046] Step 2: Driven by the cylinder, the upper jaw of the film-tearing clamp is moved by the linkage mechanism to make contact with the fixed lower jaw and close to clamp the film, and then perform a film-tearing action.

[0047] Step 3: After the first film-tearing action is completed, the secondary auxiliary film-tearing clamp assembly lowers the pneumatic gripper and closes, clamping the two sides of the film that has been torn off by the first gripper. Then, the two sets of grippers perform the second film-tearing action together until the film tearing is completed.

[0048] Step 4: After the membrane tearing is complete, the two sets of air grippers open, and the air blowing function at the gripper position is activated to blow the torn membrane into the waste membrane collection mechanism. Then, the waste membrane residue detection fiber optic cable detects whether there is any waste membrane residue at the gripper position. If there is no abnormality, the next membrane tearing operation continues.

[0049] This invention designs a high-force film-tearing gripper mechanism. This high-force film-tearing gripper mechanism mainly serves substrates with film adhered to the back and notched edges, and can also serve film-tearing needs in other special cases. This high-force film-tearing gripper mechanism is equipped with two sets of film-tearing grippers. The primary linkage film-tearing gripper uses a unique pneumatic linkage mechanism, and the upper and lower grippers are connected by line contact, which can effectively clamp the film. The film-tearing gripper's clamping force is much greater than that of ordinary pneumatic film-tearing grippers. A secondary auxiliary film-tearing gripper is also provided. The two sets of grippers clamp the film sequentially and perform the film-tearing action together, which can solve the problem of film tearing with high adhesion.

[0050] This high-force film-tearing gripper mechanism is compact and fully functional. Compared to traditional manual film tearing or methods using consumables, this mechanism is equipped with a film-tearing resistance alarm and fiber optic detection for residual film at the gripper position, preventing damage to the substrate during tearing. It also occupies little space, performs a simple tearing action, and can be used with film-tearing equipment for different types of substrates. Furthermore, the mechanism includes an air-blowing function to prevent waste film from sticking to the grippers and assists in the collection of waste film generated during tearing. This mechanism also has good compatibility; for substrates of various widths and with notched edges commonly found in the industry, film tearing can be performed by adjusting the gripper installation position.
