Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electronic component placement equipment, and in particular to a pin shaping structure, a material taking device and a placement machine. Background Art
[0002] The plug-in machine is mainly used for the insertion of electronic components. During operation, the material picking device capable of planar movement moves to the picking position to take out the positioned and shaped electronic components and adjust the insertion posture. Then the material picking device moves to the corresponding position above the positioned PCB board to insert the electronic components. Generally, the shaping of electronic components is completed before picking. However, even if some electronic components with too long pins are shaped in advance, they will still be deformed when they are out of the shaping position. For example, if the reserved tolerance of the insertion hole on the PCB board is too small, it is easy to fail in insertion. Although the shaping function is also set in the picking device, the current structural setting of the shaping function is unreasonable, and the structure of the entire shaping function is complicated.

[0007] The above-mentioned pin shaping structure has at least the following beneficial effects: The driving rod of the first driving member is arranged to be movable along the first direction, and the first transmission member is arranged to be slidable along the second direction. By converting the movement along the first direction into the movement along the second direction through the first transmission member, the width dimension of the first shaping portion or the second shaping portion along the second direction can be made smaller and more compact. The first shaping member and the second shaping member can be driven by the first driving member to approach each other and dock or move away from each other. The shaping cavity formed after the docking of the first shaping member and the second shaping member can shape the pins of the electronic component located between the first shaping member and the second shaping member. When the pin shaping structure of the present application is installed on the picking device of the plug-in machine, the existing Z-axis of the picking device can be directly utilized. After the first shaping member and the second shaping member are docked, the pins of the electronic component picked by the picking head can be shaped. Then, the first shaping portion, the second shaping portion, and the picking head are synchronously lifted and lowered to complete the insertion of the electronic component.
[0008] According to the pin shaping structure described in the first aspect embodiment of the present application, the first transmission structure includes a cam and a guide groove that cooperate with each other. The cam is arranged on the driving rod, and the guide groove is arranged on the first transmission member. The connection line between the two ends of the guide groove is inclined with respect to the driving rod.

[0010] According to the pin shaping structure described in the first aspect embodiment of the present application, the two guide grooves are arranged in parallel or symmetrically.
[0011] According to the pin shaping structure described in the first aspect embodiment of the present application, the first shaping member has a plurality of first shaping grooves arranged in an array, and the second shaping member has second shaping grooves corresponding to the first shaping grooves. After the first shaping member and the second shaping member are docked, the first shaping grooves and the second shaping grooves form the shaping cavity.
[0012] According to the pin shaping structure described in the first aspect embodiment of the present application, the first shaping member includes a first docking layer. The first docking layer has a plurality of first grooves arranged in an array. A first convex portion is formed between two adjacent first grooves. The bottom of the first groove forms the first shaping groove. The second shaping member includes a second docking layer. The second docking layer has a plurality of second grooves arranged in an array. The second grooves are adapted to the first convex portions. A second convex portion adapted to the first groove is formed between two adjacent second grooves. The top of the second convex portion forms the second shaping groove.

The fourth docking layer has a number of fourth grooves arranged in an array, and a fourth protrusion adapted to the third groove is formed between two adjacent fourth grooves. The fourth protrusion is arranged in a dislocation manner with the first protrusion, and the first shaping groove extends to the fourth protrusion.
[0015] According to the embodiments of the second aspect of the present application, a picking device is provided, including the above-mentioned pin shaping structure.
[0016] The above-mentioned picking device has the following beneficial effects: When the electronic components picked up by one of the picking heads need to be shaped, the picking heads on the two sliding members adjacent to the picking head are removed and the first shaping part and the second shaping part are respectively installed, so that the addition of the pin shaping structure does not require re-changing the interval arrangement of the first driving module, and the components of the existing picking device are effectively utilized. Specifically, during shaping, the picking device reaches the designated picking position under the drive of the motion module of the plug-in machine, and the picking head descends to the designated position under the action of the first driving module to pick up materials, and returns to the original position after picking up the materials; during the process of the picking device moving to the designated plug-in position, the first shaping part and the second shaping part descend to the set position under the drive of the corresponding first driving module, and the first shaping member and the second shaping member approach and dock with each other, so as to shape the pins of the electronic components clamped by the picking head. When the picking device moves to the designated plug-in position, the first shaping part, the second shaping part and the picking head descend synchronously to complete the correct pre-insertion of the electronic components into the PCB board. After the pre-insertion is completed, the first shaping member and the second shaping member release the pin shaping of the electronic components and return to the original position, and the picking head continues to descend to realize the complete insertion of the electronic components. After the electronic components are inserted, the first shaping part, the second shaping part and the picking head return to the original position synchronously, and then continue the next round of insertion.

Detailed implementation manners
[0033] This section will describe in detail the specific embodiments of the present application. The preferred embodiments of the present application are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present application. However, it should not be construed as a limitation on the protection scope of the present application.
[0034] In the description of the present application, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc., is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the present application.
[0035] In the description of the present application, the meaning of several is one or more, the meaning of multiple is more than two, and understandings such as greater than, less than, exceeding, etc. do not include the present number, and understandings such as above, below, within, etc. include the present number. If there is a description of first and second, it is only for the purpose of distinguishing technical features and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.
[0036] In the description of the present application, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present application in combination with the specific content of the technical solution.
[0037] The plug-in machine generally includes an X-axis and a Y-axis. The component picking device is arranged on the X-axis or Y-axis. Generally, multiple picking heads 200 are provided on the component picking device. The axis used to drive the picking head 200 to perform linear reciprocating motion is called the Z-axis. The smaller the distance between two adjacent picking heads 200, the more picking heads 200 of the same size can be arranged on the component picking device. More picking heads 200 mean that more electronic components 400 can be inserted, and the insertion efficiency is also faster.
[0038] However, with the increasing variety of inserted components, it also means more precise requirements for insertion. The tolerance reserved for the insertion holes of some PCB boards is small (such as the holes for digital tubes). When inserting the corresponding electronic components 400, more precise pin sizes are required. If the components are still inserted after simple shaping as before, it is easy to cause insertion failure and damage to the electronic components 400 (only shaping before insertion is likely to cause the pins to deform and rebound), which also affects the insertion efficiency. Therefore, to ensure the accuracy of insertion, it is necessary to ensure that the pins of the electronic components 400 are of the correct size during the insertion process. Currently, although there is also a shaping function set on the component picking device, the current structure of the shaping function is unreasonable, and the entire structure of the shaping function is complex. It is not convenient to be directly installed on the picking head 200 for use.
[0039] Refer to Figure 7 、 Figure 8 、 Figure 11 and Figure 12 According to FIGS., the pin shaping structure of the embodiment of the present application includes a first shaping portion 310 and a second shaping portion 320 which are oppositely arranged. The first shaping portion 310 includes a second transmission module and a first shaping member 312. The second shaping portion 320 includes a second transmission module and a second shaping member 322. The second shaping portion 320 includes a first driving member 301 and a first transmission member 306 that can slide along a second direction. The first transmission member 306 is used to fix the first shaping member 312 or the second shaping member 322. Specifically, that is, the first transmission member 306 belonging to the first shaping portion 310 is used for the installation of the first shaping member 312. The first shaping member 312 is fixed to the first transmission member 306 by bolts. The first transmission member 306 belonging to the second shaping portion 320 is used for the installation of the second shaping member 322. The second shaping member 322 is fixed to the first transmission member 306 by bolts. Further, the first driving member 301 has a driving rod that can move along a first direction. The driving rod is connected to the first transmission member 306 through a first transmission structure, so that the first shaping member 312 and the second shaping member 322 can approach each other and dock or move away from each other. Among them, the first direction is perpendicular to the second direction. After the first shaping member 312 and the second shaping member 322 approach each other and dock, a plurality of shaping cavities 330 are formed.
[0040] Among them, the driving rod of the first driving member 301 is arranged to be able to move in the first direction, and the first transmission member 306 is arranged to be able to slide in the second direction. By converting the movement in the first direction into the movement in the second direction through the first transmission member 306, the width dimension of the first shaping portion 310 or the second shaping portion 320 in the second direction can be made smaller and more compact. By driving the first shaping member 312 and the second shaping member 322 by the first driving member 301, they can approach or move away from each other. The shaping cavity 330 formed after the docking of the first shaping member 312 and the second shaping member 322 can shape the pins of the electronic component located between the first shaping member 312 and the second shaping member 322.
[0041] When the pin shaping structure of the present application is installed on the material taking device of the plug-in machine, it can directly utilize the existing Z-axis of the material taking device. By docking the first shaping member 312 and the second shaping member 322, the pins of the electronic component picked up by the material taking head are shaped. Then, the first shaping portion 310, the second shaping portion 320, and the material taking head are synchronously lifted and lowered to complete the insertion of the electronic component.
[0042] In some embodiments, the first transmission structure includes a cam 303 and a guide groove 305 that cooperate with each other. The cam 303 is arranged on the driving rod, and the first transmission member 306 is provided with the guide groove 305. The cam 303 is located in the guide groove 305. Since the connection line between the two ends of the guide groove 305 is inclined with respect to the driving rod, when the driving rod drives the cam 303 to move from one end of the guide groove 305 to the other end, the first shaping member 312 or the second shaping member 322 arranged on the first transmission member 306 can perform a linear reciprocating motion. Each first transmission member 306 is provided with a guide groove 305. The guide groove 305 can be a regular straight groove, or an irregular or regular arc groove. As long as the connection line between the two ends of the guide groove 305 is inclined with respect to the driving rod, the vertical movement of the driving rod can be converted into the horizontal movement of the first transmission member 306. It should be noted that the mutually cooperating cam 303 and guide groove 305 enable the entire first shaping portion 310 or the second shaping portion 320 to be designed more compactly.
[0043] The movements of the first shaping member 312 and the second shaping member 322 both adopt the rolling friction between the cam 303 and the guide groove 305 to achieve the synchronous approach or separation of the first shaping member 312 and the second shaping member 322. The friction is small, the lateral stroke is large, and the movement is smooth, which is suitable for high-speed movement.
[0044] In a preferred embodiment, the first driving member 301 is a cylinder, and the driving rod is the cylinder rod of the cylinder. In some other embodiments, the first driving member 301 can also be an electric push rod.
[0045] Specifically, both the first shaping part 310 and the second shaping part 320 are provided with fixing seats 304. The air cylinders are fixed to the fixing seats 304. A guiding block 302 is provided on the air cylinder rod of the air cylinder. A cam 303 is arranged on the guiding block 302. The guiding block 302 is slidably arranged on the fixing seat 304 through a guide rail slider structure to prevent the self-rotation of the air cylinder rod. The first transmission part 306 is also slidably arranged on the fixing seat 304 through a guide rail slider structure. The guide rail slider structure for the first transmission part 306 includes a second guide rail 342 and a second slider 341, so that the first transmission part 306 can slide along the second direction.
[0046] In some embodiments, the two guiding grooves 305 are arranged in parallel or symmetrically. When the two guiding grooves 305 are arranged in parallel, when one air cylinder extends and the other air cylinder contracts, the first shaping member 312 and the second shaping member 322 can approach each other and dock or move away from each other. In the embodiments of the present application, as Figure 7 and Figure 8 shown, the two guiding grooves 305 are arranged symmetrically. When the two air cylinders extend or contract synchronously, the first shaping member 312 and the second shaping member 322 can approach each other and dock or move away from each other.
[0047] In the embodiments of the present application, as Figures 9 to 12 shown, the first shaping member 312 has a plurality of first shaping grooves 3125 arranged in an array. The second shaping member 322 has second shaping grooves 3225 corresponding to the first shaping grooves 3125. After the first shaping member 312 and the second shaping member 322 are docked, the first shaping grooves 3125 and the second shaping grooves 3225 form a shaping cavity 330. The first shaping grooves 3125 and the second shaping grooves 3225 correspond to each other one by one. The formed plurality of shaping cavities 330 are consistent with the pin distribution of the electronic component 400 to be shaped. So that when the first shaping member 312 and the second shaping member 322 approach each other and dock, the formed shaping cavity 330 can shape and fix the pins of the electronic component 400. The shaping cavities 330 of the present application can be adaptively adjusted according to the pins of different electronic components 400.
[0048] That is to say, after the first shaping member 312 and the second shaping member 322 are docked, the setting of the shaping grooves can align and correct each pin of the electronic component 400, ensuring that each pin remains in the target position before plugging and ensuring accurate pre-plugging alignment.
[0049] Specifically, the first shaping member 312 includes a first docking layer. The first docking layer has a plurality of first grooves 3121 arranged in an array. A first convex portion 3122 is formed between two adjacent first grooves 3121. The bottom of the first groove 3121 forms a first shaping groove 3125. The second shaping member 322 includes a second docking layer. The second docking layer has a plurality of second grooves 3222 arranged in an array. The second grooves 3222 are adapted to the first convex portions 3122. A second convex portion 3221 adapted to the first groove 3121 is formed between two adjacent second grooves 3222. The top of the second convex portion 3221 forms a second shaping groove 3225. When the first shaping member 312 and the second shaping member 322 approach and dock with each other, the first convex portions 3122 are inserted into the second grooves 3222, and the second convex portions 3221 are inserted into the first grooves 3121, ensuring the accurate docking of the first shaping groove 3125 and the second shaping groove 3225, making the shaping more precise. In the embodiment of the present application, both the second groove 3222 and the first groove 3121 are V-shaped, and the first shaping groove 3125 and the second shaping groove 3225 can be arc-shaped grooves. The first shaping groove 3125 is provided at the bottom of the first groove 3121, which can effectively guide the pins of the electronic component 400 into the first shaping groove 3125 and has a guiding effect.
[0050] In some embodiments, the second shaping member 322 further includes a third docking layer adjacent to the second docking layer. The third docking layer has a plurality of third grooves 3224 arranged in an array. A third convex portion 3223 is formed between two adjacent third grooves 3224. The third convex portion 3223 is arranged in a staggered manner with the second convex portion 3221. The second shaping groove 3225 extends to the bottom of the third groove 3224. The addition of the third groove 3224 can also effectively guide the pins of the electronic component 400 into the second shaping groove 3225 and has a guiding effect, and the shaping effect of the extended second shaping groove 3225 is better.
[0051] Furthermore, the first shaping member 312 further includes a fourth docking layer adjacent to the first docking layer. The fourth docking layer has a plurality of fourth grooves 3123 arranged in an array. A fourth convex portion adapted to the third groove 3224 is formed between two adjacent fourth grooves 3123. The fourth convex portion is arranged in a staggered manner with the first convex portion 3122. The first shaping groove 3125 extends to the fourth convex portion. When the first shaping member 312 and the second shaping member 322 approach and dock with each other, the fourth convex portion is inserted into the third groove 3224, the third convex portion 3223 is inserted into the fourth groove 3123, the first convex portion 3122 is inserted into the second groove 3222, and the second convex portion 3221 is inserted into the first groove 3121, ensuring the accurate docking of the first shaping groove 3125 and the second shaping groove 3225, making the shaping more precise, and ensuring that the distance between two adjacent pins is a preset distance.
[0052] The embodiment of the present application further provides a material taking device, which includes at least one material taking head 200, at least three first driving modules 110 arranged at intervals, and the above-mentioned pin shaping structure. Each first driving module 110 has a sliding member 113 capable of linear motion along the first direction. The first shaping part 310, the material taking head 200, and the second shaping part 320 are respectively arranged on three adjacent sliding members 113 in sequence.
[0053] Specifically, as Figures 1 to 3 shown, generally, the first driving module 110 is mainly used for driving the material taking head 200, that is, the first driving module 110 is the Z axis, so that the material taking head 200 can perform reciprocating motion to realize material taking or plug-in actions. Arranging multiple groups of first driving modules 110 at reasonable intervals according to the size of the material taking head 200 can enable a material taking device to be adapted to the installation of multiple material taking heads 200. In the embodiment of the present application, as Figure 13 shown, the material taking head 200 includes two clamping blocks 230 that can approach each other. There is a space between the two clamping blocks 230 for accommodating the electronic component 400. Among them, the material taking head 200 can be a parallel pneumatic claw.
[0054] Specifically, during shaping, the material taking device reaches the specified material taking position under the drive of the motion module of the plug-in machine. The material taking head 200 descends to the specified position under the action of the first driving module 110 to take materials, and returns to the original position after taking materials; during the process of the material taking device moving to the specified plug-in position, the first shaping part 310 and the second shaping part 320 descend to the set position under the drive of the corresponding first driving module 110. At this time, the pins of the electronic component 400 are between the first shaping member 312 and the second shaping member 322. Then, the first shaping member 312 and the second shaping member 322 approach each other and dock to realize shaping the pins of the electronic component 400 clamped by the material taking head 200. When the material taking device moves to the specified plug-in position, the first shaping part 310, the second shaping part 320, and the material taking head 200 descend synchronously to complete the correct pre-insertion of the electronic component 400 into the PCB board. After the pre-insertion is completed, the first shaping member 312 and the second shaping member 322 release the pin shaping of the electronic component 400 and return to the original position. The material taking head 200 continues to descend to realize the complete insertion of the electronic component 400. After the electronic component 400 is inserted, the first shaping part 310, the second shaping part 320, and the material taking head 200 return to the original position synchronously, and then continue the next round of insertion.
[0055] It should be noted that when there is no need to perform shaping treatment on the components, the first shaping part 310 and the second shaping part 320 can also be removed and replaced with the material taking head 200 without re-changing the parts. The entire shaping module has strong adaptability, and it can also enable the material taking device to switch between shaping and non-shaping.
[0056] In the embodiments of the present application, as Figures 1 to 6 shown, the material taking device includes a mounting substrate 101, and the first driving modules 110 are arranged in an array on the mounting substrate 101. The first driving module 110 includes a first motor 120 and two parallel first guide rails 111. Among them, there is a ball screw 112 between the two first guide rails 111. After the first motor 120 is fixed to the mounting substrate 101, it is rotationally connected to the ball screw 112 rotatably arranged on the mounting substrate 101 through a coupling (the rotational installation of the ball screw 112 is realized through a screw support seat). The sliding member 113 is bolted to the slider on the first guide rail 111, and the screw nut of the ball screw 112 is bolted to the sliding member 113, so that the sliding member 113 can perform a linear reciprocating motion.
[0057] Of course, in some other embodiments, the first driving module 110 may also be provided with a rotational driving part for the rotation of the material taking head 200, so that the material taking head 200 can adjust the material taking posture of the chuck. Specifically, the rotational driving part includes a second motor 130 and a ball spline 140. The second motor 130 is fixed to the mounting substrate 101. The ball spline 140 has two splines. One spline is rotatably arranged on the mounting substrate 101 through a bearing, and this spline is connected to the second motor 130 through a synchronous pulley and a synchronous belt. The other spline is rotatably arranged on the sliding member 113 through a bearing, and the material taking head 200 is fixedly connected to the spline shaft of the ball spline 140. The setting of the ball spline 140 enables the material taking head 200 to rotate while performing a linear motion. Of course, if the material taking head 200 does not need to rotate, the material taking head 200 can be directly fixed to the sliding member 113.
[0058] Specifically, as Figures 4 to 12 shown, the first transmission member 306 is arranged to be able to slide in a direction perpendicular to the moving direction of the sliding member 113. The first shaping member 312 or the second shaping member 322 is fixed to the first transmission member 306. The first driving member 301 is connected to the first transmission member 306 through a first transmission structure, so that the first transmission member 306 can perform a reciprocating motion. Reasonably arrange the arrangement direction of the first driving member 301, and at the same time, the newly designed first transmission structure can greatly reduce the specific sizes of the first shaping part 310 and the second shaping part 320, so that the first shaping part 310 and the second shaping part 320 will not affect the material taking and plugging operations of the material taking head 200 after being installed on the first driving module 110.
[0059] The first driving member 301 is a cylinder, and the cylinder rod of the cylinder is parallel to the moving direction of the sliding member 113. If the action direction of the cylinder rod is parallel to the moving direction of the sliding member 113, the sizes of the first shaping portion 310 or the second shaping portion 320 will be greatly increased. Therefore, the spacing of the first driving module 110 needs to be adapted to the sizes of the first shaping portion 310 or the second shaping portion 320. By setting the cylinder rod of the cylinder to be parallel to the moving direction of the sliding member 113 and then optimizing the first transmission structure, the first shaping portion 310 or the second shaping portion 320 can be made not larger than the sliding member 113, so that the first shaping portion 310 or the second shaping portion 320 can be adapted and installed on the existing material taking device without re-designing and arranging the material taking device.
[0060] The embodiment of the present application also provides a plug-in machine with the above-mentioned material taking device. When the plug-in machine needs to shape a certain electronic component 400, part of the material taking head 200 is replaced with the first shaping portion 310 and the second shaping portion 320 to realize shaping the electronic component 400 during the plug-in process. When the component to be plugged does not need to be shaped, the first shaping portion 310 and the second shaping portion 320 are removed, and then the corresponding material taking head 200 is replaced to realize the plug-in of more electronic components 400. This enables the plug-in machine to quickly switch between shaping and non-shaping, and the setting of the shaping module does not require re-designing the material taking device, with strong adaptability.
[0061] The above has described the embodiments of the present application in detail with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present application.
