Description

Technical Field

[0001] The present application relates to the technical field of electronic component assembly and processing, and in particular to a pickup head exchange device of an insertion machine. Background Art

[0002] In recent years, with the vigorous development of industrial automation and intelligent equipment, many automation equipment innovations have been launched to replace manual labor. Among them, there is an automatic plug-in machine that can deal with the plug-in of special-shaped electronic components on PCB boards, replacing manual plug-in with machine intelligent plug-in. The plug-in machine is a machine that automatically installs electronic components on printed circuit boards according to the program. The automatic plug-in machine mainly relies on the pickup head (claw type / suction cup type) to pick up electronic components for plug-in. During the automatic plug-in process, due to the different types and sizes of electronic components, it is necessary to change the pickup head to pick up the electronic components.

[0003] In order to adapt to the shape of electronic components, current automatic insertion machines need to replace the corresponding pick-up heads for better picking up electronic components. The process of replacing the pick-up heads is generally done manually, by manually finding the pick-up heads for installation and storing the removed pick-up heads.

[0070] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0071] See also Figure 1-18The present invention discloses a pick-up head exchange device 100 of an insertion machine, which is installed on the insertion machine and is used to pick up special-shaped electronic components. Special-shaped electronic components refer to electronic components that are different from traditional components in terms of shape, size, structure, material, etc. Their appearance can be arbitrary and is not restricted by traditional components, so they have higher design freedom and wider application fields. There are many types of special-shaped components, including capacitors, inductors, resistors, transistors, diodes, integrated circuits, etc. in various shapes. The shapes of these components can be round, square, triangular, elliptical, irregular, etc., and can even be three-dimensional. Their sizes can also be customized according to needs, and they can be picked up and processed for equipment that needs clamping, such as loading and unloading, PCB board patch production, etc.

[0072] The device includes a control identification module 5, a replacement mechanism 1, at least two picking mechanisms 2, a placement mechanism 3, an exhaust mechanism 4, and a moving mechanism. The moving mechanism is connected to the replacement mechanism 1, and the exhaust mechanism 4 is connected to the replacement mechanism 1. The control identification module 5 is connected to the moving mechanism, the exhaust mechanism 4, and the placement mechanism 3. The placement mechanism 3 is provided with at least two placement positions 32, including a first placement position 321 and a second placement position 322. The first picking mechanism 21 is placed in the first placement position 321, and the second picking mechanism 22 is placed in the second placement position 322. The replacement mechanism 1 is connected to any one of the picking mechanisms 2. The moving mechanism is used to drive the replacement mechanism 1. The control identification module 5 is used to identify the position of the placement position 32 and to identify whether there is a picking mechanism 2 on the placement position 32.

[0073] Specifically, the exhaust mechanism 4 is used to extract the gas in the replacement mechanism 1, so that the replacement mechanism 1 is in a vacuum state. One end of the picking mechanism 2 corresponds to the structure of the replacement mechanism 1, and the other end picks up the electronic component. The placement mechanism 3 can be placed on the picking mechanism 2 that can pick up different types of electronic components, and the replacement mechanism 1 can be connected to different picking mechanisms 2. The control identification module 5 can identify whether the placement position 32 is vacant, and can also identify the type of electronic component that can be picked up by the picking mechanism 2 placed in the placement position 32. The user inputs the type of electronic component currently picked up to the control identification module 5, and the control identification module 5 obtains the type of electronic component currently picked up. According to the type of electronic component, the replacement mechanism 1 connects to the corresponding picking mechanism 2 for picking up, which increases the rate of replacing the pickup head, improves production efficiency, and increases the degree of automation of the equipment.

[0074] In addition, the replacement mechanism removes the used picking mechanism and places it on a vacant placement position, moves the replacement mechanism to other placement positions and replaces it with another picking mechanism for use, thereby achieving the purpose of automatically storing the picking heads. At the same time, the picking heads are placed in the device at the same time, avoiding manual selection and providing corresponding picking heads, reducing manual operation time, and increasing the rate of replacing the picking heads.

[0075] Furthermore, different picking mechanisms 2 can be placed on the placement position 32, and the picking mechanisms 2 can pick up corresponding types of electronic components, but different picking mechanisms 2 can be connected to the same replacement mechanism 1, so that the same replacement mechanism 1 can be replaced with different types of picking mechanisms 2 to pick up different types of electronic components, solving the problem of universal compatibility of picking heads of different special-shaped electronic components.

[0076] As an embodiment, the moving mechanism can adopt any kind of conveying mechanism such as a robotic arm, a linear guide group, a conveyor belt, etc. In this embodiment, the moving mechanism adopts the structure of a linear guide group to move the replacement mechanism 1, but the moving mechanism is not limited to the linear guide group used in this embodiment.

[0077] The replacement mechanism 1 includes a connecting tube 11, a limit spring 13, a limit pin 14, a sleeve 15, and a retaining ball 16. The sleeve 15 and the limit spring 13 are both sleeved on the outer peripheral side of the connecting tube 11 and installed on one end of the connecting tube 11. The limit pin 14 is inserted into the connecting tube 11. The sleeve 15 is provided with two slide grooves. Both ends of the limit pin 14 slide in the two slide grooves. The retaining ball 16 is provided between the connecting pipe and the sleeve 15. The connecting tube 11 is provided with a first hole position 12. The sleeve 15 is provided with a second hole position 17. The retaining ball 16 can be retained in the first hole position 12 or the second hole position 17.

[0078] Specifically, one end of the connecting tube 11 is connected to the vacuum mechanism 4, and the other end is connected to the picking mechanism 2. The vacuum mechanism 4 draws air to make the inside of the connecting tube 11 in a vacuum state. The picking mechanism 2 is inserted into the connecting tube 11, and the state of grabbing and releasing the electronic components in the picking mechanism 2 is switched from the vacuum state to the broken vacuum state or from the non-vacuum state to the vacuum state. The connecting tube 11 is connected to one end of the picking mechanism 2, and a protrusion is provided on the connecting tube 11. A limit spring 13 is provided between the protrusion and one end of the sleeve 15. The connecting tube 11 and the sleeve 15 are connected through the limit spring 13. A limit portion is provided in the connecting tube 11, and the limit portion contacts the connection end of the picking mechanism 2. A gasket is also provided on the limit portion to increase the air tightness between the connecting tube 11 and the picking mechanism 2.

[0079] Specifically, the sleeve 15 can move along the direction of the connecting tube 11. The sleeve 15 is configured to be trumpet-shaped, with the trumpet mouth facing the picking mechanism 2. Usually, the position of the trumpet mouth bears external force. When the sleeve 15 receives external force, the sleeve 15 moves toward the end of the connecting tube 11 connected to the air extraction mechanism 4. The sleeve 15 compresses the limit spring 13. When the force received by the sleeve 15 disappears, the limit spring 13 can push the sleeve 15 back to its original position. The limit pin 14 is inserted into the connecting tube 11. The sleeve 15 is provided with two opposite slide grooves. Both ends of the limit pin 14 are inserted into the slide grooves. The sleeve 15 moves along the connecting tube 11. The limit pin 14 slides in the slide groove. The position of the trumpet mouth of the slide groove near the sleeve 15 is an opening. The limit pin 14 can enter the slide groove from the opening and slide in the slide groove, which can limit the distance that the sleeve 15 moves in the connecting tube 11.

[0080] Specifically, the retaining ball 16 is installed in the gap between the sleeve 15 and the connecting tube 11. The inner diameter of the inner side of the connecting tube 11 on the first hole 12 is smaller than the inner diameter of the outer side, and the inner diameter of the second hole 17 close to the connecting tube 11 is larger than the inner diameter of the outer side of the sleeve 15, which can prevent the retaining ball 16 from leaking from the inside of the connecting tube 11 or the outside of the sleeve 15. Since the inner wall of the sleeve 15 is similar to a trumpet shape, the inner diameter near the connecting tube 11 is smaller than the inner diameter near the trumpet mouth. When the sleeve 15 moves along the connecting tube 11, the retaining ball 16 will move between the first hole 12 and the second hole 17. It can be understood that when the sleeve 15 moves along the connecting tube 11 toward the picking mechanism 2, the holding ball 16 is pressed into the first hole 12 by the inner wall of the sleeve 15. At this time, the connecting end of the picking mechanism 2 contacts the gasket in the connecting tube 11, and the exhaust mechanism 4 extracts gas to make the connecting tube 11 in a vacuum state, and a vacuum is formed between the connecting tube 11 and the picking mechanism 2; when the sleeve 15 moves along the connecting tube 11 toward the exhaust mechanism 4, the holding ball 16 is no longer pressed by the inner wall of the sleeve 15, and the holding ball 16 moves to the second hole 17. At this time, the connecting end of the picking mechanism 2 is separated from the connecting tube 11, and the exhaust mechanism 4 no longer exhausts gas, and the vacuum state in the connecting tube 11 is broken.

[0081] A limiting groove is set at the position where the first picking mechanism 21 and the second picking mechanism 22 are connected to the connecting tube 11. The size of the limiting groove matches the holding ball 16. The holding ball 16 is in the first hole 12 and is pressed by the sleeve 15 so that it is pressed toward the inside of the first hole 12. When the first picking mechanism 21 is inserted into the replacement mechanism 1, the holding ball 16 is clamped into the limiting groove of the first connecting tube 11, thereby limiting the first picking mechanism 21 and the second picking mechanism 22 from being disconnected from the connecting tube 11. That is, the sleeve 15 presses the holding ball 16 so that the holding ball 16 is pressed against the first hole 12, and part of the holding ball 16 is exposed into the connecting tube 11, and the exposed part can be clamped into the limiting groove, thereby limiting the first picking mechanism 21 and the second picking mechanism 22 through the holding ball 16, so that the replacement mechanism 1 is connected to the first picking mechanism 21 or the second picking mechanism 22.

[0082] In particular, the retaining ball 16 is in the first hole 12. Due to the size setting of the first hole 12, the opening of the first hole close to the inner wall is smaller than the diameter of the retaining ball 16, so that the retaining ball 16 can be partially exposed into the connecting tube 11, thereby being retained in the limiting groove, and the retaining ball 16 cannot fall from the first hole 12 to the connecting tube 11.

[0083] The picking mechanism 2 includes a first picking mechanism 21 and a second picking mechanism 22, wherein the first picking mechanism 21 and the second picking mechanism 22 pick up different types of electronic components. In this example, the first picking mechanism 21 is a gripper 2131 type picking head, and the second picking mechanism 22 is a nozzle type picking head, but the picking method of the picking mechanism 2 and the corresponding type of electronic components picked up can also be different, and are not limited to the type used in this embodiment.

[0084] The first picking mechanism 21 includes a first connecting tube 211, a first piston assembly 212, a clamping jaw assembly 213, and a first limiting pin 214. The connecting tube is connected to the first piston assembly 212, the clamping jaw assembly 213 is connected to the first piston assembly 212, the first limiting pin 214 passes through the first connecting tube 211 and the first piston assembly 212, and the clamping jaw assembly 213 and the connecting tube are installed at opposite ends of the first piston assembly 212.

[0085] Specifically, the first connecting tube 211 is used to be inserted into the connecting tube 11 and communicate with the connecting tube 11. One end of the first connecting tube 211 contacts the gasket inside the connecting tube 11. The first connecting tube 211 is buckled on the connecting tube of the first piston assembly 212. The connecting tube of the first piston assembly 212 is communicated with the internal cavity. The first connecting tube 211 is communicated with the cavity inside the second piston 2123 assembly. The vacuum mechanism 4 draws air into the connecting tube 11 to put the first connecting tube 211 and the first piston assembly 212 in a vacuum state. The first limiting pin 214 is used to fix the first connecting tube 211 and the first piston assembly 212 to ensure a stable connection between the first piston assembly 212 and the first connecting tube 211 to prevent the first connecting tube 211 from detaching from the first piston assembly 212. The piston 2123 moves in the first piston assembly 212 to allow the connected clamping jaw assembly 213 to grab electronic components.

[0086] In addition, the limiting groove is installed on the first connecting tube 211 so as to facilitate the holding ball 16 to limit the first connecting tube 211 on the connecting through tube 11 .

[0087] The first piston assembly 212 includes a cylinder body 2121, a first compression spring 2122 and a piston 2123; a connecting pipe is provided outside the cylinder body 2121, an open cavity is provided inside the cylinder body 2121, the first compression spring 2122 is sleeved on the connecting pipe, the piston 2123 is interference matched with the cylinder body 2121, and the outer peripheral side of the piston 2123 is in contact with the inner wall of the cavity.

[0088] Specifically, the piston 2123 can move in the cylinder body 2121, and the first compression spring 2122 is arranged between the first connecting tube 211 and the first piston assembly 212, one end of which is against the protrusion of the first connecting tube 211, and the other end is in contact with the surface of the cylinder body 2121. The first compression spring 2122 can allow the first piston assembly 212 to approach or move away from the first connecting tube 211. The piston 2123 is arranged in an open cavity. Due to the interference fit between the piston 2123 and the cylinder body 2121, the space between the piston 2123 and the cylinder body 2121 can be controlled by the connecting tube on the cylinder body 2121, that is, the air extraction of the exhaust mechanism 4 can affect the air pressure in the connecting tube.

[0089] In addition, a sliding groove is provided on the connecting tube of the cylinder body 2121, and both ends of the first limit pin 214 pass through the sliding groove. The first picking mechanism 21 is also provided with a head spring, which is arranged between the first connecting tube 211 and the first piston assembly 212, with one end abutting against the protrusion of the first connecting tube 211, and the other end contacting with the surface of the cylinder body 2121. The first piston assembly 212 can be approached or moved away from the first connecting tube 211 through the head spring. When the end of the clamping jaw assembly 213 contacts an external object, a force is applied to the head spring. The head spring contracts, which can avoid the force of the clamping jaw 2131 sinking being directly applied to the PCB board, thereby preventing too much pressure from being applied to the PCB board when clamping or releasing the placed electronic components, thereby protecting the PCB board.

[0090] The clamping jaw assembly 213 includes at least two clamping jaws 2131, two pins 2132, and a spring 2133 between the clamping jaws. The cylinder body 2121 is provided with two protrusions at the opening edge of the open cavity, and the protrusions are provided with at least two openings. Both ends of the pin 2132 are inserted into the two openings. Two clamping jaws 2131 are arranged between the protrusions, and the pin 2132 is arranged through the clamping jaws 2131. A limiting tooth is provided at one end of the piston 2123 away from the cylinder body 2121, and any of the clamping jaws 2131 is provided with a sliding groove, and the limiting tooth is inserted into the sliding groove. The spring 2133 between the clamping jaws is sleeved on any of the pins 2132, and the two ends of the spring 2133 between the clamping jaws are respectively connected to one of the clamping jaws 2131.

[0091] Specifically, a triangular limiting tooth and two stepped limiting teeth are provided at the bottom of the piston 2123. There is a certain space between the stepped limiting teeth and the triangular limiting teeth. A sliding groove is provided on the clamping jaw 2131. The stepped limiting teeth are inserted into the sliding groove and move along the space between the limiting teeth. Since there is a certain inclination angle in the space between the limiting teeth, the clamping jaw 2131 can be relatively close to or away from the piston 2123. At the same time, it can also be relatively close to or away from the piston 2123. A socket is provided on the clamping jaw 2131 corresponding to the pin 2132. The two pins 2132 are parallel to each other. The arrangement can allow the limit teeth to be arranged between the pins 2132, so that the limit teeth can move more smoothly relative to the pins 2132 without being hindered by the pins 2132. The two ends of the claw spring 2133 are connected to the clamping jaws 2131. When the piston 2123 moves into the cylinder 2121, the limit teeth rise, and the clamping jaws 2131 are relatively close to compress the claw spring 2133, so that the electronic components can be grasped. When the piston 2123 is pushed out of the cylinder 2121, the limit teeth are lowered, and the clamping jaws 2131 are relatively far away, and the claw spring 2133 returns to its original state, releasing the grasped electronic components. The claw spring 2133 can pull the clamping jaw 2131 back to its original position, reducing the force required to push the limit teeth, and can also avoid the situation where the two clamping jaws 2131 do not move synchronously with the limit teeth.

[0092] A plurality of holes are arranged at the end of the clamping jaws 2131 for grasping the electronic components. The holes are also arranged relatively to each other on the two clamping jaws 2131 arranged opposite to each other. The long strip electronic components can be picked up through the holes on the clamping jaws 2131. The two ends of the electronic components can be inserted into the holes. The clamping jaws 2131 are brought closer to grasp the two ends of the electronic components and pick up the electronic components, thereby achieving the purpose of picking up the electronic components.

[0093] For electronic components with pins such as resistors and capacitors, the pins of such electronic components can be bent and adjusted to be parallel to each other. The pins are inserted into the holes of the clamp 2131 and are put on the pins through the holes of the clamp 2131 to pick up the electronic components.

[0094] The working process of connecting the replacement mechanism 1 with the picking mechanism 2 is as follows (using the first picking mechanism 21): the replacement mechanism 1 is close to the placement position 32 where the first picking mechanism 21 is placed, the connecting tube 11 descends, the connecting tube 11 is sleeved on the first connecting tube 211, the exhaust mechanism exhausts air, the placement mechanism 3 opens the lock on the first picking mechanism 21, so that the first connecting tube 211 is sucked by the connecting tube 11, the sleeve holding member 15 is pressed against the placement platform 31, so that the sleeve holding member 15 is pressed against the limit spring 13, the limit spring 13 contracts, the holding ball 16 moves to the second hole 17, and the first connecting tube 211 is inserted into the connecting tube 11. When the first connecting tube 211 is on The limiting groove penetrates to a position flush with the second hole position 17, the connecting tube 11 is lifted, the limiting spring 13 is extended, pushing the sleeve 15 to return to its original position, and the holding ball 16 is pressed back into the first hole position 12. The holding ball 16 is pushed by the sleeve 15 and partially enters the limiting groove and is held on the limiting groove. Due to the air suction effect of the exhaust mechanism, the holding ball 16 can be continuously kept in the first hole position 12, so that the first connecting tube 211 is continuously held by the holding ball 16 on the connecting tube 11. The lifting of the replacement mechanism 1 can maintain the connection between the first connecting tube 211 and the connecting tube 11. When the first picking mechanism 21 completes the lifting, the continuous air suction can be stopped.

[0095] The working process of disengaging the replacement mechanism 1 from the picking mechanism 2 is as follows (using the first picking mechanism 21): the replacement mechanism 1 is pressed on the placement platform 31, and the sleeve 15 is pressed on the placement platform 31. At the same time, the vacuum mechanism stops pumping air and inflates the interior to move the first connecting tube 211 in the direction of disengaging from the connecting tube 11. The sleeve 15 moves toward the limit spring 13, and the holding ball 16 moves to the second hole position 17. The inflation of the vacuum mechanism can also allow the holding ball 16 to remain in the position of the second hole position 17. The first connecting tube 211 is disengaged from the sleeve of the connecting tube 11, the replacement mechanism 1 releases the picking mechanism 2, continues to rise, and the placement mechanism 3 locks the first picking mechanism 21.

[0096] The second picking mechanism 22 includes a second connecting tube 221, a first connecting member 222, a second connecting member 223, a second compression spring 224, and a second limiting pin 225. The second connecting tube 221 is connected to the first connecting member 222, the first connecting member 222 is connected to the second connecting member 223, the second compression spring 224 is sleeved on the second connecting tube 221, and the second limiting pin 225 passes through the second connecting tube 221 and the first connecting member 222.

[0097] Specifically, an annular protrusion is provided on the first connecting piece 222, and two ends of the second compression spring 224 are respectively connected to the annular protrusion and the first connecting piece 222, and the second compression spring 224 is limited between the annular protrusion and the first connecting piece 222. Connecting tubes are respectively provided on both sides of the first connecting piece 222, and the connecting tube close to the first connecting tube 211 is provided with two opposite sliding grooves, and the second limiting pin 225 is inserted into the sliding groove, and the two ends of the second limiting pin 225 pass through the sliding groove. When the second picking mechanism 22 is pressed against the PCB board, the first connecting piece 222 is pressed and approached to the second connecting tube 221, and the force applied to the second connecting tube 221 is applied to the second compression spring 224, so that the second connecting piece 223 cannot generate the same force on the PCB board, thereby avoiding applying a large pressure to the PCB board and causing damage. The connecting tube on the first connecting member 222 is provided with a second connecting member 223, and the second connecting member 223 is inserted into the connecting tube on the first connecting member 222. A gasket is provided between the second connecting member 223 and the first connecting member 222. At the same time, the first connecting tube 211 and the connecting tube on the first connecting member 222 are interference-fitted, which can increase the air tightness inside the second picking mechanism 22. Since the second connecting tube 221, the first connecting member 222, and the second connecting member 223 of the second picking mechanism 22 are internally connected, the second picking mechanism 22 and the replacement mechanism 1 are kept in atmospheric balance, and the gas inside the second picking mechanism 22 and the replacement mechanism 1 can be extracted by the exhaust mechanism 4. By extracting the internal gas, the end of the second connecting member 223 can absorb electronic components, and can pick up special-shaped electronic components that the first picking mechanism 21 cannot directly pick up, so that the exchange device can pick up more types of electronic components.

[0098] The first limit pin 214 passes through the first connecting tube 211 and extends to the outside for a certain length, and the second limit pin 225 passes through the second connecting tube 221 and extends to the outside for a certain length. Four openings with matching shapes are provided at the end of the connecting tube 11, and the openings match the first limit pin 214 or the second limit pin 225. The connecting tube 11 is buckled on the first connecting tube 211 or the second connecting tube 221. The first limit pin 214 supports the first connecting tube 211, or the second limit pin 225 supports the second connecting tube 221. The connection between the connecting tube 11 and the first connecting tube 211 or the second connecting tube 221 is faster, and there is no need for position calibration and docking, so that the connection between the device replacement mechanism 1 and the picking mechanism 2 is fool-proof.

[0099] In addition, two first hole positions 12 are provided on the connecting tube 11, and the two first hole positions 12 are 90° apart in the setting positions of the connecting tube 11, which can facilitate the installation of the sleeve tube on the connecting tube 11. When the operator installs the replacement mechanism 1, the retaining ball 16 is inserted into the first hole position 12 of the connecting tube 11, and then the second hole position 17 of the sleeve tube is installed corresponding to the retaining ball 16. Due to the connection relationship of the limit spring 13, the retaining ball 16, the first hole position 12, and the second hole position 17 are in the same horizontal direction. The setting of the two first hole positions 12 can increase the installation speed of the connecting tube 11 and the sleeve tube, and make the installation of the connecting tube 11 fool-proof, avoiding the operator's inability to calibrate the positions of the first hole position 12 and the second hole position 17 well during installation.

[0100] In addition, a limiting groove is also provided on the second connecting tube 221 to facilitate the holding ball 16 to limit the second connecting tube 221 on the connecting through tube 11 .

[0101] The placement mechanism 3 includes a placement platform 31, a lifting component 33, a blocking component 34, a pushing component 35, and a base. The lifting component 33 is connected to the placement platform 31, the blocking component 34 is connected to the placement platform 31, and the pushing component 35 is connected to the blocking component 34.

[0102] Specifically, the jacking component 33 is installed on the base, the jacking component 33 is vertically arranged, the jacking component 33 is composed of a jacking cylinder, one end of the jacking component 33 is installed on the base, and the other end is installed with the placement platform 31. The lifting of the jacking component 33 can lift the placement platform 31. A plurality of placement positions 32 are arranged on the placement platform 31, and the placement positions 32 can place the picking mechanism 2. The blocking component 34 includes a baffle, which is installed on the placement platform 31. An opening is opened on the baffle, and the inner diameter of the opening is the same as the inner diameter of the placement position 32, so as to facilitate the picking mechanism 2. To enter and be grabbed out, the pushing component 35 includes a pushing cylinder, which is used to push the baffle to move. A slide groove that matches the size and shape of the baffle is set on the placement platform 31. The baffle is inserted into the slide groove, and the pushing component 35 can drive the baffle to slide. The pushing component 35 contracts and can drive the baffle to retract. The opening position is misaligned with the placement position 32 to block the picking mechanism 2. When the picking mechanism 2 needs to be grabbed, the pushing component 35 is extended, and the baffle is inserted deep into the slide groove until the opening position is aligned with the placement position 32. Only then can the picking mechanism 2 be picked up from the placement platform 31.

[0103] It can be understood that the baffle can prevent the picking mechanism 2 in the placement position 32 from being directly pulled out, and the picking mechanism 2 can be placed directly on the placement platform 31. When the replacement mechanism 1 replaces the picking mechanism 2, the used picking mechanism 2 can be directly placed in the placement position 32 on the placement platform 31, and other picking mechanisms 2 can be grabbed. The device can simultaneously solve the problems of storage, fully automatic replacement, and compatibility of different types of picking mechanisms 2 without manual processing. At the same time, there is no need to consider the storage of the picking mechanism 2 after use, so that the line change efficiency in production is improved.

[0104] As an embodiment, the placement platform 31 is provided with a pickup head support assembly 36, and the pickup head support assembly 36 is arranged on the inner wall of the placement position 32. The pickup head support assembly 36 includes a support member and a support spring, and the support spring is connected to the support member. The placement position 32 corresponds to the support member and is provided with an arc-shaped sliding groove. The placement position 32 is arranged to pass through the support platform. The picking mechanism 2 is placed above the support member, and the support member presses the support spring to achieve the function of supporting the picking mechanism 2.

[0105] In particular, the bottom of the picking mechanism 2 is suspended in the air when it is placed at the placement position 32, that is, the placement mechanism 3 is arranged in a tubular shape on the placement position 32, and the edge of the picking mechanism 2 is supported by the picking mechanism 2, and the bottom and top of the edge of the picking mechanism 2 are suspended in the air, thereby reducing the collision of the structures below, such as the clamping jaws and the suction nozzle, with other positions, preventing the mechanism from being damaged, and protecting the structures, such as the clamping jaws and the suction nozzle.

[0106] The control and identification module 5 includes an identification module, a positioning module and a control module, wherein the control module is connected to the identification module and the positioning module, the positioning module can locate the position of the placement position 32 and the position of the electronic components to be picked up, the identification module is used to identify whether there is a picking mechanism 2 on the placement position 32 and to identify the type of the picking mechanism 2 on the placement position 32, the identification module detects the picking mechanism 2 by detecting whether there is an object at the placement position 32 when the placement platform 31 is raised, and the control module can control the movement of the moving mechanism and the start or shut down of other mechanisms and modules.

[0107] The control module has built-in data on the types of special-shaped electronic components that can be grabbed by the picking mechanism 2. The user sends the type of electronic components that need to be picked up to the control module, and the control module selects the corresponding picking mechanism 2 for picking up according to the built-in data information.

[0108] The identification module uses a sensor to sense whether there is a picking mechanism 2 in the placement position 32, and the type of the picking mechanism 2. Different types of picking mechanisms 2 are provided with different types of sensing chips. The identification module uses a sensing probe for identification. The control module has a built-in chip corresponding to the type of sensing chip carried by the picking mechanism 2. The sensing probe is used to identify and determine the type of electronic components that can be picked up by the current picking mechanism 2. The sensor and the sensing probe are installed at the edge of the placement position 32 to facilitate the detection of the picking mechanism 2 and the type of electronic components that can be picked up by the picking mechanism 2.

[0109] The positioning module adopts image recognition to perform positioning. Specifically, the positioning module includes a camera, which contains an image recognition chip. The camera is installed above the placement mechanism 3 and shoots towards the placement position 32. The camera takes real-time photos of the current workstation, performs image recognition on the real-time photos, identifies whether there is a picking mechanism 2 at the current placement position 32, and locates the placement position where the picking mechanism 2 is not placed. In addition, a camera component is arranged on the loading device, and the camera component is used to locate the position of the electronic component that currently needs to be picked up, so that the subsequent control module can control the replacement mechanism 1 to pick up the picking mechanism 2 of the corresponding electronic component for picking up.

[0110] Specifically, the identification module detects whether there is a picking mechanism 2 in the placement position 32, and identifies whether the picking mechanism 2 placed on the placement position 32 is the type of picking mechanism 2 that can be used for the electronic components currently input by the user. The identification module senses the appropriate picking mechanism 2 according to the information built into the control module. The identification module feeds back to the control module through an electrical signal. The control module controls the pushing component 35 to drive the baffle to move so that the opening on the baffle is aligned with the placement position 32. In addition, the positioning module locates the position of the placement position 32, the control module drives the moving mechanism to move, and the control module controls the replacement mechanism 1 to grab the corresponding picking mechanism 2, thereby completing the step of grabbing the picking mechanism 2. The position of the electronic component loading can also be located according to the positioning module. The control module drives the moving mechanism, the replacement mechanism 1, and the picking mechanism 2 to move to the corresponding position to pick up the electronic components.

[0111] As an embodiment, the recognition module uses an infrared sensor for sensing. The recognition module is set at the opening of the placement position 32. When the picking mechanism 2 leaves the placement position 32, the recognition module can sense and identify that there is no picking mechanism 2 in the current placement position 32. The control recognition module 5 senses and identifies whether there is a picking mechanism 2 in the placement position 32 before the replacement mechanism 1 moves, thereby knowing whether there is a picking mechanism 2 in the current placement position 32.

[0112] As an embodiment, the identification module may use a pressure sensor, which is installed on the pickup head support assembly 36. The pressure sensor is connected to the support member. When the pickup mechanism 2 is placed in the placement position 32, the blocking assembly 34 presses the edge of the pickup mechanism 2, thereby pressing the pressure sensor and the support member. The pressure sensor senses the pressure of the pickup mechanism 2 and sends an electrical signal to the control module, thereby letting the control module know that there is a pickup mechanism 2 in the current placement position 32.

[0113] In a second aspect, the present invention discloses a method for replacing a pickup head of an insertion machine, which specifically comprises the following steps:

[0114] Step S1: The mobile mechanism is loaded with a quick-change head, and the mobile mechanism loaded with the quick-change head moves the quick-change head to the exchange station;

[0115] Step S2: Select a pickup head according to the type of electronic component, and connect the quick-change head to the corresponding pickup head;

[0116] Step S3: The moving mechanism drives the picking head to move to the feeding device to pick up the material and move the material to the corresponding position.

[0117] In step S1, one end of the quick-change head is connected to the vacuum mechanism, and the interior of the quick-change head is tubular. The vacuum mechanism needs to extract the gas inside the quick-change head to make the interior of the quick-change head in a vacuum state, or input gas into the quick-change head to break the vacuum state inside the quick-change head. A positioning and identification mechanism is correspondingly installed on the moving mechanism, which is used to locate and identify the position of the exchange station and the position of the picking head.

[0118] In step S2, the pickup head adopts different picking methods corresponding to different electronic components, including adsorption, clamping and the like. The structure of the pickup head is also different corresponding to the different picking methods, but the structure of the corresponding quick connector and the method of connecting with the quick connector are the same. Therefore, different types of pickup heads can be picked up by a single quick connector, and the pickup head can normally pick up the corresponding type of electronic components.

[0119] In step S3, the feeding device can be a feeder, which outputs electronic components one by one in sequence, and the quick-change head and the picking head pick up the loaded electronic components one by one. The moving mechanism drives the picked up electronic components to the position where they need to be placed, such as a PCB board.

[0120] Specifically, a quick-change head is loaded on the moving mechanism, and the quick-change head is connected to the exhaust mechanism. The moving mechanism moves the quick-change head to the exchange station and aligns it with the picking head that needs to be grabbed on the exchange station. The quick-change head is aligned with the picking head, and the exhaust mechanism makes the interior of the quick-change head and the picking head in a vacuum state by exhausting air, so that the quick-change head adsorbs the picking head. After the quick-change head adsorbs the picking head, the quick-change head and the picking head are clamped, and the quick-change head and the picking head are stably connected. After the moving mechanism grabs the picking head from the exchange station, it moves to the feeding equipment to pick up corresponding special-shaped electronic components and other materials. The exhaust mechanism extracts the air between the quick-change head and the picking head, so that the interior is converted from a vacuum state to a non-vacuum state and from a non-vacuum state to a vacuum state, thereby picking up special-shaped electronic components of the type corresponding to the picking head.

[0121] It can be understood that different special-shaped electronic components require corresponding types of pickup heads for picking up, and different types of pickup heads can be connected to the quick connector to meet the needs of picking up various types of special-shaped electronic components, solving the problem that the corresponding type of pickup head cannot be automatically replaced when picking up special-shaped electronic components. When picking up special-shaped electronic components, different types of pickup heads appear, and the corresponding type of pickup heads can be automatically replaced to improve production efficiency. When PCB boards are produced, the pickup heads can be quickly replaced for the corresponding electronic components to avoid affecting the production speed due to problems such as the placement and replacement of the pickup heads. At the same time, the picking speed of various electronic components is also improved.
