Description

Technical Field

[0001] The present application relates to the field of surface mounting technology, and in particular to a tray removing head device. Background Art

[0002] The placement machine, also known as the placement machine, is an extremely core equipment in the SMT (Surface Mount Technology) industry production line. It is mainly used to place electronic components on circuit boards. Generally, the placement machine accounts for more than 60% of the total investment of the SMT production line, and the production capacity of the production line is also mainly determined by the placement machine. Among them, the material tray of the feeding station can convey the material tape to the placement machine so that the placement machine can complete the placement work. Usually, when the material tape in the old material tray of the feeding station is about to run out, the operator needs to remove the old material tray on the feeding station, take a new material tray, manually tear the material head (tape head) off the material tape, and then crimp the material tape and manually place the new material tray on the feeding station to continue the old material tray. On the one hand, manual tearing of the material head and manual replacement of the material tray are inefficient and easily affect the production efficiency of the production line. In addition, the labor cost increases year by year, and the cost overhead is high. On the other hand, manual operation is prone to errors, especially for SMT equipment, which has a variety of material types and a high frequency of replenishment (especially 7-inch material trays). If the personnel operate improperly, errors are more likely to occur, affecting the production line.

[0003] Therefore, how to improve the technical defects in the prior art and develop equipment that can perform the material tray removal head process before material replacement for the placement machine has always been a problem that ordinary technicians in this field need to solve urgently.

At the same time, the present application also provides an upper cutter head. While the lower cutter head shovels up the material head, the upper cutter head and the lower cutter head gradually close until the shoveled material head is clamped to achieve the clamping of the material head. At this time, the upper cutter head and the lower cutter head can be driven to move by the transfer module to achieve the tearing off of the material head, so as to facilitate the subsequent material head shearing operation.

At the same time, a suction hole is provided on the side of the upper cutter head facing the lower cutter head. After the lower cutter head scoops up the material head, air is blown outwards through the blowing hole to blow the material head onto the upper cutter head, and then the material head is adsorbed onto the upper cutter head by using the suction hole, so that the upper cutter head and the lower cutter head can clamp the material head better, which is less prone to errors, and the material head is flatter after clamping, which is conducive to the upper and lower cutter heads clamping the material head and tearing off the material strip.

[0034] 4. In the present application, the material head disassembly mechanism also includes a camera module, a laser sensor, and a slide that can drive the camera module to move.

In this way, regardless of the size of the material tray or the amount of material belt in the material tray, the camera module in the present application can obtain the position of the material head through image acquisition, which has strong versatility and a wide range of applications.

[0035] 5. In the present application, the tray disassembly head device also includes a tray pick-up and placement mechanism, which can realize automatic loading and unloading of the tray, for example, conveying the tray to the tray clamping mechanism, or conveying the cut tray from the tray clamping mechanism to the tray temporary storage rack.

In addition, the tray pick-up and placement mechanism is also provided with a pressure wheel, which can convey the tape to the bottom of the restraining roller on the tray temporary storage station, so that when the tray is stored in the tray temporary storage rack, the torn tape can be kept in a torn state, so that the tape on the tray can be directly spliced ​​later without repeatedly tearing the tape.

[0060] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various components of the present application are not absolute but relative. These descriptions are appropriate when these components are in the positions shown in the drawings.

[0061] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0062] According to a specific embodiment provided by the present invention, see Figures 1 to 3 A material tray head removal device includes a material tray clamping mechanism, a head removal mechanism 200 and a cutting mechanism 300. The material tray clamping mechanism is used to clamp a material tray 700 to be removed, the head removal mechanism 200 is used to search, clamp and tear off a head 720 on the material tray 700, and the cutting mechanism 300 is used to cut off a material-free area on a material belt 710, so as to prepare the material tray head removal process before material replacement for the placement machine.

[0063] Specifically, see Figure 3 and Figure 4The stripping head mechanism 200 includes a stripping head body and a transfer module for driving the stripping head body to move. The stripping head body further includes an upper cutter head 210, a lower cutter head 220, and a first drive member 230 for driving the upper cutter head 210 and the lower cutter head 220 to open and close. The first drive member 230 can be a cylinder. Among them, at least the head end of the lower cutter head 220 is in a shovel-shaped structure, which can scoop up the material head 720 of the material belt 710 on the material tray 700. After the material head 720 is scooped up, the upper cutter head 210 and the lower cutter head 220 can continue to approach each other until they are closed to clamp the scooped material head 720, thereby achieving the clamping of the material head 720. After the material stripping head body (upper blade head 210, lower blade head 220) clamps the material head 720, the transfer module can drive the material stripping head body to move away from the material tray 700, so that the material stripping head body tears the material belt 710, thereby tearing off the material head 720 for the subsequent cutting operation of the material head 720.

[0064] Specifically, see Figure 1 and Figure 2 The tray clamping mechanism includes a first clamping member 110, a second clamping member 120, and a third driving member 130 for driving the first clamping member 110 and the second clamping member 120 to open and close. The third driving member 130 can be a cylinder. The first clamping member 110 and the second clamping member 120 are used to stably clamp the tray 700 so that the lower cutter head 220 can better scoop up the material head 720. Among them, the first clamping member 110 (or the second clamping member 120) is provided with a rotating shaft 140 suitable for passing through the center hole of the tray 700, so that the tray 700 can rotate around the center line of the rotating shaft 140 relative to the tray clamping mechanism, which is conducive to the tray head removal device to find the material head 720 and tear off the material belt 710 after clamping the material head 720.

[0065] For example, see Figure 2 and Figure 3 The tray clamping mechanism is also provided with a rotating motor 601 capable of driving the rotating shaft 140 to rotate, and the stripping head mechanism 200 also includes a camera module 602, which can collect image information of the tray 700. In this way, when the rotating motor 601 drives the rotating shaft 140 to drive the tray 700 to rotate, the position of the material head 720 on the tray 700 can be obtained through the camera module 602. That is, the rotating motor 601 drives the rotating shaft 140 to rotate until the camera module 602 recognizes different color modules (the material heads 720 on the tray 700 are distinguished by different colors), the rotating motor 601 stops running, and the stripping head body scoops up and tears the material heads 720.

[0066] Further, see Figure 7The cutting mechanism 300 includes an electric scissors 310. After the material stripping head body tears the material strip 710, the electric scissors 310 can cut off the material strip 720 in the material-free area, so that the material stripping head device of the material tray can automatically complete the head search, clamping, tearing and cutting operations of the material strip 710, so as to complete the material stripping head 720 process of the material tray 700 before material replacement for the placement machine, and the equipment has a higher degree of automation, which is conducive to improving the production efficiency of the production line.

[0067] The cutting mechanism 300 further includes two oppositely arranged material belt grippers, namely a first material belt gripper 321 and a second material belt gripper 322, wherein the first material belt gripper 320 is on the same side as the material tray clamping mechanism 100, and the second material belt gripper 330 is on the same side as the material stripping head mechanism 200. After the material stripping head mechanism 200 tears the material belt 710, the first material belt gripper 320 and the second material belt gripper 330 alternately clamp and pull the material belt 710 downward, and when the material head is pulled to the cutting position, the electric scissors 310 cut off the material head 720 in the material-free area. Specifically, after the stripping head mechanism 200 tears and clamps the material belt 710, the first material belt gripper 320 first moves forward to clamp the material belt 710 and pulls it downward, the stripping head mechanism 200 releases the material belt 710 and moves backward, then the second material belt gripper 330 clamps the material belt 710, the first material belt gripper 320 releases the material belt 710 and moves downward, and the second material belt gripper 330 pulls the material belt 710 downward; then, the first material belt gripper 320 re-clamps the material belt 710. 0, the second material belt gripper 330 releases the material belt 710 and moves downward; then, the second material belt gripper 330 clamps the material belt 710, the first material belt gripper 320 releases the material belt 710, and the second material belt gripper 330 pulls down the material belt 710, and this reciprocating process is repeated until the material belt 710 is torn to completely expose the material area, and the electric scissors 310 move to the junction between the material area and the non-material area to cut it, thereby cutting off the material head 720 with the non-material area.

[0068] In this embodiment, the material strip 710 is torn by setting the first material strip gripper 320 and the second material strip gripper 330. Compared with tearing the material strip 710 with a single gripper, the first material strip gripper 320 and the second material strip gripper 330 need to move within a smaller range, which is more conducive to the high concentration setting of the equipment and reduces the volume of the tray removing head device.

[0069] Among them, in order to ensure the tension and straightness of the material strip 710 during the tearing process, when the first material strip gripper 320 and the second material strip gripper 330 pull the material strip 710 downward, the rotating motor 601 on the material tray clamping mechanism needs to cooperate with the two material strip grippers to control the rotation of the rotating shaft 140, thereby constraining the material strip 710 to be tensioned and in a straight line without loosening, so that the electric scissors 310 can cut off the material head 720 with the material-free area in one stroke.

[0070] The cutting mechanism 300 should also be provided with a camera module 602, which can collect image information of the material belt 710. When it detects the material area of ​​the material belt 710, the electric scissors 310 move to the junction between the material area and the material-free area to cut it, so as to cut off the material head 720 with the material-free area.

[0071] In actual production, the cutting mechanism 300 can be directly integrated into the tray clamping mechanism and located between the first clamping member 110 and the second clamping member 120. The tray stripping head device has a smaller size and a higher degree of equipment integration.

[0072] In a preferred embodiment, see Figure 5 A blowing hole 222 is provided on the side of the lower cutter head 220 facing the upper cutter head 210, which can blow the scooped material head 720 toward the upper cutter head 210; at the same time, a suction hole (not shown) is provided on the side of the upper cutter head 210 facing the lower cutter head 220, which can adsorb the material head 720 that has been blown toward the upper cutter head 210, so that it will not fall back toward the lower cutter head 220. The upper cutter head 210 and the lower cutter head 220 can better clamp the material head 720, which is less prone to errors, and the clamped material head 720 is flatter, which is beneficial for the upper cutter head 210 and the lower cutter head 220 to clamp the material head 720 and tear off the material strip 710.

[0073] Specifically, see Figures 3 to 5 The upper cutter head 210 includes a main body 211 and a first clamping portion 212 disposed at the side edge of the main body 211. The main body 211 is further provided with a first docking portion 213 located below the first clamping portion 212. A through hole is provided on the first docking portion 213. The lower cutter head 220 includes a second clamping portion 221 and a second docking portion 223. The second docking portion 223 is provided in the through hole. The second clamping portion 221 is provided at one end of the second docking portion 223 facing the first clamping portion 212 and has a shovel-shaped structure. The first driving member 230 can realize the opening and closing of the upper cutter head 210 and the lower cutter head 220 by driving the second docking portion 223 to rise and fall. After the camera module 602 finds the material head 720, the transfer module drives the material stripping head body to approach the material tray 700, and the first drive component 230 drives the lower cutter head 220 to rise to scoop up the material head 720. After scooping up the material head 720, the first drive component 230 continues to drive the lower cutter head 220 to rise until the upper cutter head 210 and the lower cutter head 220 close to clamp the material head 720. The transfer module then drives the material stripping head body to move, so that the material stripping head body tears open the material belt 710, thereby tearing off the material head 720, and completing the material tray material stripping process before material replacement for the SMT machine.

[0074] As a preference, see Figure 3The stripping head mechanism 200 is provided with a stopper 240 on the side of the second docking portion 223 away from the lower cutter head 220, the stopper 240 is drivingly connected to the first driving member 230, and a buffer 250 is provided between the stopper 240 and the second docking portion 223. The buffer 250 can be a spring, which can realize the elastic resistance of the lower cutter head 220 to the material belt 710, so that the lower cutter head 220 is not easy to scratch the material belt 710 when shoveling the material head 720.

[0075] Furthermore, the main body 211 of the upper cutter head 210 is of a plate-shaped structure, and its axial width of the tray 700 clamped by the tray clamping mechanism is relatively small, so it can adapt to trays 700 of different sizes, and facilitate the removal head body to extend into the tray 700 from the side to clamp, tear off, and other operations on the material head 720 thereon, and has strong versatility.

[0076] In actual production, see Figure 2 and Figure 3 A supporting member 290 may also be provided at the upper end of the upper cutter head 210, which can prop open the material tray 700 before the upper cutter head 210 and the lower cutter head 220 are inserted into the material tray 700, making it easier for the upper cutter head 210 and the lower cutter head 220 to insert into the material tray 700 and perform operations such as clamping and tearing off the material heads 720 thereon, and is highly practical.

[0077] Specifically, see Figure 5 , one side of the second clamping portion 221 facing the first clamping portion 212 is an inclined surface, and the inclined surface is inclined toward the side away from the second docking portion 223 and close to the main body 211 to form the above-mentioned shovel-shaped structure. At the same time, one side of the first clamping portion 212 facing the second clamping portion 221 is arranged parallel to the inclined surface. On the one hand, the setting of the inclined surface is more conducive to the lower blade 220 scooping up the material head 720; on the other hand, it can make the first clamping portion 212 and the second clamping portion 221 fit better and the fitting area is larger, which is more conducive to clamping the material head 720, not easy to loosen, and not easy to tear the material strip 710 in the process of tearing the material strip 710. The structural setting is more reasonable and practical.

[0078] Specifically, see Figure 3 The transfer module includes a vertical transfer module 261, a first horizontal transfer module 262 and a second horizontal transfer module 263. The material stripping head body is mounted on the vertical transfer module, the vertical transfer module is mounted on the first horizontal transfer module 262, and the first horizontal transfer module 262 is mounted on the second horizontal transfer module 263. At this time, the second horizontal transfer module 263 is suitable for driving the first horizontal transfer module 262, the vertical transfer module and the material stripping head body to move axially along the material tray 700 clamped by the material tray clamping mechanism; the first horizontal transfer module 262 is suitable for driving the vertical transfer module and the material stripping head body to move radially along the material tray 700 clamped by the material tray clamping mechanism; the vertical transfer module is suitable for driving the material stripping head body to rise and fall.

[0079] This embodiment provides a first vertical transfer module 261, a first horizontal transfer module 262 and a second horizontal transfer module 263, so that the stripping head body can be moved in six directions (three-axis movement), thereby improving the flexibility of the stripping head body, especially the first horizontal transfer module 262. It can also control the depth of the stripping head body extending into the material tray 700, so that the material head 720 can be clamped and torn off the material trays 700 of different sizes and specifications, and has strong versatility.

[0080] Specifically, the material stripping head body extends into the material tray 700 to a depth of 15 mm to 105 mm, for example, Figure 6 As shown, it can not only adapt to 7-inch and 13-inch feed trays, but also can further adapt to full and half-full feed trays.

[0081] In actual production, the arrangement of the first vertical transfer module 261, the first horizontal transfer module 262 and the second horizontal transfer module 263 is not limited. The second horizontal transfer module 263 can also be set on the first horizontal transfer module 262, and the first horizontal transfer module 262 can be set on the first vertical transfer module 261, and so on. As long as the three-axis movement of the stripping head body can be realized, it is within the protection scope of this application.

[0082] In a preferred embodiment, see Figure 3 The stripping head mechanism 200 further includes a laser sensor 270, a slide (not shown) and a fixed frame 280. The fixed frame 280 is installed on the stripping head body, the slide and the laser sensor 270 are installed on the fixed frame 280, and the camera module 602 is installed on the slide. Among them, the laser sensor 270 can be used to measure the radius of the material belt circle in the material tray 700. The slide is configured to drive the camera module 602 to move according to the data measured by the laser sensor 270, so that the material belt 710 is located in the focus area of ​​the camera module 602. In this way, regardless of the size of the material tray 700 or the amount of material belt in the material tray 700, the camera module 602 in this embodiment can obtain the position of the material head 720 through image acquisition, and assist the stripping head mechanism 200 to automatically complete the search, clamping, tearing and other operations of the material head 720, which has strong versatility and a wide range of applications.

[0083] In a specific embodiment, see Figure 1 , Figure 8 and Fig. 9The tray head removal device also includes a tray pick-up and placement mechanism 400, which is used to grab and transport the tray 700. For example, the tray 700 transported from the previous process is clamped and placed on the tray clamping mechanism, and the tray 700 with the material-free area cut off is removed from the tray clamping mechanism. The tray pick-up and placement mechanism 400 may specifically include a clamping claw 410 and a clamping claw cylinder 420 for driving the clamping claw 410 to open and close. When the clamping claw 410 is opened and pressed against the wall of the central hole of the tray 700, the tray pick-up and placement mechanism 400 grabs the tray 700. When the clamping claw 410 is closed, the tray 700 is separated from the tray pick-up and placement mechanism 400.

[0084] In order to prevent the cut material head 720 from re-sticking and affecting the subsequent splicing of the material strip 710, the material tray placement mechanism 400 should also include a material strip fixing gripper 430 for clamping the material strip 710 after the material tray 700 is torn, so as to keep the material strip 710 (material head 720) in a torn state.

[0085] In a specific embodiment, see Figure 1 and Fig.10 The tray head removal device also includes a tray temporary storage station 500, which has a plurality of accommodating slots 510 for storing trays 700 with cut-off material-free areas. After a certain number of trays 700 are stored, they are transported to the SMT assembly line via an AGV trolley for automatic material receiving and changing procedures.

[0086] Among them, see Fig. 9 The tray pick-up and placement mechanism 400 further includes a photoelectric sensor 440. When the tray pick-up and placement mechanism 400 grabs the tray 700 with the material-free area cut off, the photoelectric sensor 440 can sense the size of the tray 700 grabbed by the claw 410. Specifically, the photoelectric sensor 440 is set at a distance of about 3.5 inches to 6.5 inches from the claw 410. When the tray 700 grabbed by the claw 410 can block the photoelectric sensor 440, the tray 700 grabbed by the claw 410 is a 13-inch tray 700. When the tray 700 grabbed by the claw 410 fails to block the photoelectric sensor 440, the tray 700 grabbed by the claw 410 is a 7-inch tray 700. In this embodiment, the photoelectric sensor 440 is provided to help the tray pick-up and placement mechanism 400 identify the size of the tray 700, so that the tray 700 is placed in a suitable accommodating groove 510, with a high degree of automation and strong practicality.

[0087] Of course, in actual production, the tray picking and placing mechanism 400 can also adopt a universal setting, that is, the accommodating groove 510 can adapt to both 7-inch trays and 13-inch trays. No further details will be given here, as they are all within the protection scope of this application.

[0088] Specifically, see Fig.10, a constraint roller 520 is provided on the upper end surface of the tray temporary storage station 500, and there is a gap between the constraint roller 520 and the upper end surface of the tray temporary storage station 500 for the material belt 710 to pass through. At the same time, the tray pick-up and place mechanism 400 also includes a second vertical transfer module 450, a pressure wheel 460 installed on the second vertical transfer module 450, and a second driving member for driving the pressure wheel 460 to rotate, wherein the second driving member can be a rotary motor 601. When the tray 700 is placed in the accommodating groove 510, the second vertical transfer module 450 drives the pressure wheel 460 to press down to press the torn material belt 710 against the upper end surface of the tray temporary storage station 500, and the second driving member drives the pressure wheel 460 to rotate and then drives the material belt 710 to move, so that the material belt 710 passes through the gap between the constraint roller 520 and the upper end surface of the tray temporary storage station 500. In this way, during the process of the AGV trolley conveying the material tray 700, the constraint roller 520 can limit the material belt 710 to prevent the material belt 710 from retreating and re-adhering due to shaking or vibration, so that it remains in a torn state, so that the material belt 710 on the material tray 700 can be directly spliced ​​later without repeatedly tearing the material belt 710. The process of removing the material head 720 of the material tray 700 before changing materials is completed for the placement machine, and the production line has higher production efficiency and lower cost.

[0089] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0090] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
