Description

Technical Field

[0001] This utility model belongs to the technical field of film-removing equipment, specifically relating to a film-removing device for electronic components. Background Technology

[0002] To prevent contamination and scratches on the surface of electronic components, a protective film is usually applied before shipment to enhance their protection. Before assembly, this protective film needs to be peeled off. Because the film is typically tightly adhered to the components, and the pre-cut gripping areas are small, peeling it off is difficult. Traditionally, this is done manually, which is repetitive and tiring, leading to operator fatigue and low efficiency, unsuitable for mass production. Furthermore, manual peeling inevitably leaves sweat, dander, dust, and other foreign matter on the component surface, potentially scratching it and preventing proper functioning in subsequent processes, ultimately resulting in a decline in the quality of the assembled product. With technological advancements, numerous film-peeling machines have been designed and developed to replace manual peeling. In actual assembly, the lifting angle of the protective film on each electronic component varies greatly. When using existing film-removing equipment, it is common for it to fail to clamp the lifting part and remove the protective film, resulting in electronic components that have not been treated with film removal flowing to the next process and causing assembly abnormalities.

[0003] The purpose of this invention is to provide an electronic component film-removing device to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0005] An electronic component film-removing device includes a driving mechanism, a film-removing mechanism, and a film-collecting mechanism. The driving mechanism is connected to the film-removing mechanism, and the film-removing mechanism cooperates with the film-collecting mechanism. The film-removing mechanism includes a pneumatic finger. A first gripper finger is fixedly connected to one gripper of the pneumatic finger, and a second gripper finger is fixedly connected to the other gripper finger. The first gripper finger and the second gripper finger cooperate. The first gripper finger has a first through hole, and the second gripper finger has a second through hole. The first through hole and the second through hole correspond to each other. The second through hole is connected to a vacuum pressure detector and a first vacuum generator.

[0006] As a further improvement, the film collection mechanism includes a collection box with a feed inlet at the top and multiple through holes at the bottom. A second vacuum generator is fixedly connected to the bottom of the collection box.

[0007] As a further improvement, the first gripper finger is provided with a boss, and a first through hole passes through the boss; the second gripper finger is provided with a groove, and a second through hole passes through the groove; the boss and the groove cooperate with each other.

[0008] As a further improvement, the drive mechanism includes a first mounting plate, on which a horizontally arranged first guide rail and a first lead screw arranged parallel to the first guide rail are fixedly mounted. A first slider is slidably connected to the first guide rail and threadedly connected to the first lead screw. A first motor is fixedly mounted on the first mounting plate, and the output shaft of the first motor is fixedly connected to one end of the first lead screw.

[0009] As a further improvement, a second mounting plate is fixedly connected to the first slider, a horizontally arranged second guide rail and a second lead screw arranged parallel to the second guide rail are fixedly mounted on the second mounting plate, the extension direction of the second guide rail is perpendicular to the extension direction of the first guide rail, a second slider is slidably connected to the second guide rail, the second slider is threadedly connected to the second lead screw, a second motor is fixedly mounted on the second mounting plate, and the output shaft of the second motor is fixedly connected to one end of the second lead screw.

[0010] As a further improvement, a third mounting plate is fixedly connected to the second slider, a vertically arranged third guide rail and a third lead screw arranged parallel to the third guide rail are fixedly mounted on the third mounting plate, a third slider is slidably connected to the third guide rail, the third slider and the third lead screw are threadedly connected, a third motor is fixedly mounted on the third mounting plate, and the output shaft of the third motor is fixedly connected to one end of the third lead screw.

[0011] As a further improvement, a fourth mounting plate is fixedly connected to the third slider, a first rotating shaft is vertically rotatably connected to the fourth mounting plate, a first pulley is fixedly mounted on the first rotating shaft, a fourth motor is fixedly mounted on the fourth mounting plate, and a second pulley is fixedly mounted on the output shaft of the fourth motor.

[0012] As a further improvement, a fifth mounting plate is fixedly connected to the bottom of the first rotating shaft. The fifth mounting plate is provided with an arc-shaped sliding groove.

[0013] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0014] This utility model provides an electronic component film-removing device. By installing a first gripper and a second gripper on a pneumatic finger, the device can clamp the raised part of the protective film. When the drive mechanism moves the pneumatic finger, it can tear the protective film off the surface of the electronic component, replacing manual operation. This not only reduces labor intensity and improves work efficiency, but also avoids affecting the appearance of the electronic component.

[0015] By setting a vacuum pressure detector on the second clamping finger, the vacuum pressure value in the second through hole can be detected. When the first and second clamping fingers fail to effectively clamp the protective film, the vacuum pressure value in the second through hole will exceed the normal range, thereby triggering an equipment alarm and preventing electronic components that have not been treated with film removal from flowing to the next process.

[0016] By setting a first vacuum generator connected to the second finger, when the first and second fingers are released, the first vacuum generator delivers gas into the second through hole to blow the protective film away from the second finger, preventing the protective film from sticking to the second finger and being unable to fall off.

[0017] By installing a second vacuum generator at the bottom of the collection box, a downward airflow is generated inside the collection box. Driven by the airflow, the torn protective film can fall into the collection box more accurately. Attached Figure Description

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this utility model, not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0026] like Figure 1-6As shown, an electronic component film-removing device includes a driving mechanism 1, a film-removing mechanism 2, and a film-collecting mechanism 3. The driving mechanism 1 is connected to the film-removing mechanism 2, and the film-removing mechanism 2 cooperates with the film-collecting mechanism 3. The film-removing mechanism 2 includes a pneumatic finger 201. A first gripper 202 is fixedly connected to one gripper of the pneumatic finger 201, and a second gripper 203 is fixedly connected to the other gripper of the pneumatic finger 201. The first gripper 202 and the second gripper 203 cooperate. The first gripper 202 is provided with a first through hole 204, and the second gripper 203 is provided with a second through hole 205. The first through hole 204 and the second through hole 205 correspond to each other. The second through hole 205 is connected to a vacuum pressure detector 206 and a first vacuum generator 207. In use, the two grippers of the pneumatic finger 201 approach each other and clamp the raised part of the protective film between the first gripper 202 and the second gripper 203. The drive mechanism 1 drives the pneumatic finger 201 to move, which can peel the protective film off the surface of the electronic component. Then, the drive mechanism 1 drives the pneumatic finger 201 to move above the film collection mechanism 3. After the two grippers of the pneumatic finger 201 are released, the peeled protective film falls into the film collection mechanism 3.

[0027] The vacuum pressure detector 206 detects the vacuum pressure value within the second through-hole 205, thereby detecting whether the first clamping finger 202 and the second clamping finger 203 effectively hold the raised portion of the protective film. Specifically, in the initial state, the first vacuum generator 207 is in a pumping state. When the first clamping finger 202 and the second clamping finger 203 effectively hold the raised portion of the protective film, the raised portion of the protective film adheres to the space between the first through-hole 204 and the second through-hole 205. Due to the sealing effect of the protective film, the second through-hole 205 is under negative pressure, and the detection value of the vacuum pressure detector 206 is within the normal range. However, when the first clamping finger 202 and the second clamping finger 203 fail to effectively hold the protective film, the second through-hole 205 is connected to the outside through the first through-hole 204 and cannot form a negative pressure. The detection value of the vacuum pressure detector 206 will exceed the normal range, and the equipment will issue an alarm. The operator will then promptly handle the abnormal situation, effectively preventing untreated electronic components from flowing into the next process.

[0028] After the drive mechanism 1 moves the pneumatic finger 201 above the film collection mechanism 3, the first vacuum generator 207 switches to the blowing state. Specifically, after the two grippers of the pneumatic finger 201 are released, the first vacuum generator 207 blows air into the second through hole 205, making the protective film more easily detach from the second gripper, preventing the protective film from being unable to detach properly due to static electricity or adhesive backing attached to the second gripper 203.

[0029] In this embodiment, the film collection mechanism 3 includes a collection box 301 for collecting the torn protective film. The collection box 301 has a feed inlet 302 at the top and multiple through holes at the bottom. A second vacuum generator 303 is fixedly connected to the bottom of the collection box 301. The second vacuum generator 303 generates a downward airflow, which helps the torn protective film fall more accurately into the collection box 301.

[0030] In this embodiment, as Figure 4 As shown, the first gripper 202 has a boss, through which a first through hole 204 passes. The second gripper 203 has a groove, through which a second through hole 205 passes. The boss and the groove engage. This engagement increases the contact area between the protective film and the first gripper 202, and between the protective film and the second gripper 203, thereby increasing the friction between them and preventing the protective film from slipping out between the first gripper 202 and the second gripper 203 during the tearing process.

[0031] In this embodiment, the drive mechanism 1 includes a first mounting plate 101, on which a horizontally arranged first guide rail 102 is fixedly mounted, and a first lead screw 103 is arranged parallel to the first guide rail 102. A first slider 104 is slidably connected to the first guide rail 102, and the first slider 104 is threadedly connected to the first lead screw 103. A first motor 105 is fixedly mounted on the first mounting plate 101, and the output shaft of the first motor 105 is fixedly connected to one end of the first lead screw 103. The first motor 105 drives the first lead screw 103 to rotate, and the first lead screw 103 drives the first slider 104 to move horizontally along the first guide rail 102.

[0032] In this embodiment, a second mounting plate 106 is fixedly connected to the first slider 104. A horizontally arranged second guide rail 107 and a second lead screw 108 arranged parallel to the second guide rail 107 are fixedly mounted on the second mounting plate 106. The extension direction of the second guide rail 107 is perpendicular to the extension direction of the first guide rail 102. A second slider 109 is slidably connected to the second guide rail 107 and threadedly connected to the second lead screw 108. A second motor 110 is fixedly mounted on the second mounting plate 106, and the output shaft of the second motor 110 is fixedly connected to one end of the second lead screw 108. The second motor 110 drives the second lead screw 108 to rotate, and the second lead screw 108 drives the second slider 109 to move horizontally along the second guide rail 107. The movement direction of the second slider 109 is perpendicular to the movement direction of the first slider 104.

[0033] In this embodiment, a third mounting plate 111 is fixedly connected to the second slider 109. A vertically arranged third guide rail 112 and a third lead screw 113 arranged parallel to the third guide rail 112 are fixedly mounted on the third mounting plate 111. A third slider 114 is slidably connected to the third guide rail 112 and threadedly connected to the third lead screw 113. A third motor 115 is fixedly mounted on the third mounting plate 111, and the output shaft of the third motor 115 is fixedly connected to one end of the third lead screw 113. The third motor 115 drives the third lead screw 113 to rotate, and the third lead screw 113 drives the third slider 114 to move vertically along the third guide rail 112.

[0034] In this embodiment, a fourth mounting plate 116 is fixedly connected to the third slider 114. A first rotating shaft 117 is vertically rotatably connected to the fourth mounting plate 116. A first pulley 118 is fixedly mounted on the first rotating shaft 117. A fourth motor 119 is fixedly mounted on the fourth mounting plate 116. A second pulley 120 is fixedly mounted on the output shaft of the fourth motor 119. The first pulley 118 and the second pulley 120 are connected by a belt 121. The fourth motor 119 drives the first rotating shaft 117 to rotate via the belt 121.

[0035] In this embodiment, a fifth mounting plate 122 is fixedly connected to the bottom of the first rotating shaft 117. The first rotating shaft 117 drives the fifth mounting plate 122 to rotate horizontally. The fifth mounting plate 122 is provided with an arc-shaped sliding groove 123. A second rotating shaft and a third rotating shaft are installed on the outer wall of the pneumatic finger 201. The second rotating shaft is rotatably connected to the center position of the sliding groove 123 on the fifth mounting plate 122, and the third rotating shaft is slidably connected within the sliding groove 123. The pneumatic finger 201 can rotate a certain angle along the trajectory of the sliding groove 123 with the second rotating shaft as the center of rotation, so that the pneumatic finger 201 can tilt, which is more conducive to adjusting the position of the pneumatic finger 201.

[0036] In this embodiment, for ease of description and clarity, the movement direction of the first slider 104 is taken as the X-axis, the movement direction of the second slider 109 as the Y-axis, and the movement direction of the third slider 114 as the Z-axis. The drive mechanism 1, through the combination of multiple linear guide rail modules, enables the pneumatic finger 201 to move in the X, Y, and Z-axis directions. By setting the fourth motor 119 and the fifth mounting plate 122, the pneumatic finger 201 can rotate horizontally and adjust its tilt angle, thereby allowing for more flexible adjustment of the pneumatic finger 201's posture. The drive mechanism 1 moves the pneumatic finger 201 to the position where the protective film is raised. The two grippers of the pneumatic finger 201 approach each other until the first gripper 202 and the second gripper 203 clamp the protective film. The drive mechanism 1 then moves the pneumatic finger 201 to peel the protective film off the surface of the electronic component. During this process, the vacuum pressure detector 206, connected to the second through-hole 205 on the second gripper 203, detects the vacuum pressure value inside the second through-hole 205. When the first gripper 202 and the second gripper 203 fail to effectively hold the raised part of the protective film, the vacuum pressure value inside the second through-hole 205 will exceed the normal range, triggering an alarm to remind the operator to handle the abnormal situation promptly. After the pneumatic finger 201 moves the torn protective film above the collection box 301, the first gripper 202 and the second gripper 203 release, and the first vacuum generator 207 blows air into the second through-hole 205, making it easier for the torn protective film to detach from the second gripper 203, preventing the protective film from failing to detach properly due to static electricity or adhesive residue on the second gripper 203.

[0037] A second vacuum generator 303 is installed at the bottom of the collection box 301. The second vacuum generator 303 generates a downward airflow. Driven by the airflow, the torn protective film can fall more accurately into the collection box 301.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
