[0052] Insertion machine is a mechanical device that automatically and standardly inserts some regular electronic components into the conductive sockets of printed circuit boards. When the insertion machine is working, it is necessary to first feed various electronic components to the clamping device of the insertion machine, and then the clamping device clamps the electronic components and accurately inserts the electronic components into the preset pin sockets of the printed circuit board to complete the insertion. However, due to the differences in the structural forms of electronic components, the clamping device is unique, that is, the same clamping device cannot be compatible with electronic components of different forms, so the corresponding clamping device needs to be replaced when clamping and inserting electronic components.

[0053] At present, the automatic replacement device of the clamping head of the existing conventional plug-in machine is still immature. When it comes to printed circuit boards with a large number and types of plug-ins, the automatic replacement device of the clamping head does not run smoothly, resulting in poor installation accuracy of the clamping head, making the quality of the electronic components connected by the clamping head poor, affecting the normal use of the printed circuit board.

[0054] In order to solve the technical problems that the clamping head replacement device of the existing plug-in machine is not stable, resulting in low installation accuracy of the clamping head 800 and poor quality of the electronic components plugged in by the clamping head 800, refer to Figures 1 to 4, an embodiment of the utility model provides an automatic replacement device for a clamping head, including an acupuncture point plate 100, a clamping plate 200 and a guide wheel 400. Among them, the acupuncture point plate 100 is provided with a plurality of acupuncture point holes 110, and the acupuncture point holes 110 are used to place the clamping head 800. In some embodiments, a part of the acupuncture point holes 110 are pre-set with clamping heads 800 of different models, corresponding to clamping electronic components of different structural forms, and another part of the acupuncture point holes 110 are empty acupuncture point holes 110, which are used to place the clamping head 800 removed from the machine head with the clamping head 800 inserted. For example, assuming that the acupuncture point plate 100 includes two rows and six columns of acupuncture point holes 110, one row can be loaded with six clamping heads 800 to replace new clamping heads 800, and the other row can be empty acupuncture point holes 110 to place the removed clamping heads 800. The clamping plate 200 is disposed on one side of the acupuncture hole 110 of the acupuncture plate 100. The clamping plate 200 is driven by the first driving unit 300. The first driving unit 300 drives the clamping plate 200 to move, so that there is a first state and a second state between the clamping plate 200 and the acupuncture hole 110. In the first state, the clamping plate 200 clamps the material clamping head 800 to the acupuncture hole 110, and in the second state, the clamping plate 200 releases the material clamping head 800 from the acupuncture hole 110. In some embodiments, the first driving unit 300 can be a driving cylinder, which is convenient for reversing movement and has a simpler structure when used as a reciprocating drive. The guide wheel 400 includes a first end wall 410, a second end wall 420 and a peripheral wall 430. The first end wall 410 and the second end wall 420 are arranged opposite to each other. The peripheral wall 430 extends from the first end wall 410 to the second end wall 420 in a straight line. The guide wheel 400 is provided with a rotating shaft 440 in a direction from the first end wall 410 to the second end wall 420 to connect the guide wheel 400 to the acupuncture point plate 100. The peripheral wall 430 abuts against the card plate 200 to convey the card plate 200 when the card plate 200 moves. In some embodiments, the guide wheel 400 can also be a spherical structure.

[0055] In the technical solution of this embodiment, a clamping head automatic replacement device is provided, which can realize automatic head replacement according to electronic components of different structural forms, and the clamping head automatic replacement device can improve the operation stability when replacing the clamping head 800, so as to ensure the installation accuracy of the clamping head 800, and further ensure the quality of plugging electronic components using the clamping head 800. The clamping head automatic replacement device includes an acupuncture point plate 100, a clamping plate 200 and a guide wheel 400. Among them, a plurality of acupoint holes 110 for placing the clamping heads 800 are opened on the acupoint plate 100, and the card plate 200 is covered on the side of the acupoint plate 100 where the acupoint holes 110 are opened, and the card plate 200 can move relative to the acupoint plate 100, so that there is a first state of clamping the clamping heads 800 between the card plate 200 and the acupoint plate 100, and there is a second state of releasing the clamping heads 800 between the card plate 200 and the acupoint plate 100, and a guide wheel 400 is arranged between the card plate 200 and the acupoint plate 100, and the guide wheel 400 is connected to the acupoint plate 100 through a rotating shaft 440, and the outer peripheral wall 430 of the guide wheel 400 is in contact with the card plate 200, so that when the card plate 200 moves, the card plate 200 can be transported by the guide wheel 400.

[0056] Specifically, when it is necessary to remove the clamping head 800, the machine head with the clamping head 800 installed is first moved toward the direction close to the acupoint plate 100, and the center of the clamping head 800 on the machine head is aligned with the center of an empty acupoint hole 110 of the acupoint plate 100. In the process of the machine head moving toward the direction close to the acupoint plate 100, the first driving unit 300 drives the clamping plate 200 to move, so that the clamping plate 200 and the acupoint hole 110 are in the second state, so as to facilitate the insertion of the clamping head 800 on the machine head into the acupoint hole 110. After the clamping head 800 on the machine head is inserted into the acupoint hole 110, the first driving unit 300 drives the clamping plate 200 to reset, so that the clamping plate 200 and the acupoint hole 110 are in the first state. At this time, the clamping head 800 is clamped in the acupoint hole 110, and the machine head moves in the direction away from the acupoint plate 100, thereby completing the disassembly of the clamping head 800. When it is necessary to load the clamping head 800, the machine head moves toward the direction close to the acupoint plate 100, and the center of the insertion head of the machine head is aligned with the center of a preset clamping head 800 of the acupoint plate 100. At the same time, the first driving part 300 drives the card plate 200 to move, so that the second state is present between the card plate 200 and the acupoint hole 110, so that the clamping head 800 can be installed on the insertion head of the machine head, so that the clamping head 800 can move in the direction away from the acupoint plate 100 together with the random head. After the clamping head 800 is installed on the insertion head of the machine head, the first driving part 300 drives the card plate 200 to reset, so that the first state is present between the card plate 200 and the acupoint hole 110, which is used to clamp the remaining clamping heads 800 in the acupoint plate 100.

[0057] The automatic clamping head replacement device provided in this embodiment can not only change the matching state between the clamping plate 200 and the acupuncture point plate 100 by moving the clamping plate 200, and realize the automatic clamping and releasing of the clamping head 800 in the acupuncture point hole 110 according to the structural form of the electronic component, but also can convert the sliding friction of the clamping plate 200 during movement into rolling friction through the guide wheel 400, thereby facilitating the improvement of the operation stability and transmission sensitivity of the clamping plate 200 during movement, thereby improving the installation accuracy of the clamping head 800, and ensuring the plug-in quality of the electronic components plugged in using the clamping head 800.

[0058] In some embodiments, reference Figure 1 to Figure 2 The card plate 200 is provided with a guide rod 210, and the acupuncture point plate 100 is provided with an elastic part 120. The guide rod 210 is penetrated by the elastic part 120. When the card plate 200 moves, the elastic part 120 is compressed or stretched. When the card plate 200 moves in the opposite direction, the elastic part 120 is released to push the card plate 200 to reset.

[0059] Specifically, in order to improve the movement accuracy of the card plate 200, ensure that the card plate 200 can be reset to the original position without deviation after movement, so as to ensure the clamping effect of the card plate 200 on the clamping head 800, in this embodiment, the movement of the card plate 200 is constrained or pushed by the elastic part 120. For example, the elastic part 120 can be a spring, and the guide rod 210 is arranged through the center of the spring, that is, the spring is wound on the guide rod 210. When the card plate 200 moves to compress or stretch the spring, the guide rod 210 can provide a guiding effect for the spring, so that the spring can only be stretched or compressed along the axial direction of the guide rod 210, thereby limiting the torsion of the spring in other directions, ensuring that the spring can provide elastic force in a single direction for the card plate 200, and then ensuring the reset accuracy of the card plate 200 under the elastic force of the spring.

[0060] In addition, during the movement of the card board 200 , the elastic portion 120 can also provide a buffering effect for the card board 200 , thereby reducing the impact force during the movement of the card board 200 and ensuring the stability of the card board 200 during the movement.

[0061] In some embodiments, reference Figure 1 to Figure 2 Along the direction of movement of the card plate 200, the card plate 200 is provided with an oblong hole 220, and a limiting bolt 230 is passed through the oblong hole 220. Along the direction of movement of the card plate 200, the oblong hole 220 and the limiting bolt 230 can move relative to each other, so as to limit the displacement of the card plate 200 on the acupuncture point plate 100 along the direction perpendicular to the movement of the card plate 200.

[0062] Specifically, in order to ensure that the card plate 200 can always reciprocate in one direction during movement and will not deviate in other directions, in the present embodiment, an oblong hole 220 is opened on the card plate 200. For example, an oblong hole 220 can be opened at the center position of the card plate 200. For another example, multiple oblong holes 220 can be opened at different positions of the card plate 200. The setting position and number of the oblong holes 220 can be adaptively adjusted according to the actual processing conditions. A limiting bolt 230 is passed through the oblong hole 220, and a clearance fit is adopted between the oblong hole 220 and the limiting bolt 230, that is, the oblong hole 220 and the limiting bolt 230 can produce relative movement in the direction of movement of the card plate 200, but can limit the relative movement in other directions. For example, assuming that the card plate 200 is configured to be able to move left and right, the oblong hole 220 and the limiting bolt 230 can produce relative movement in the left and right direction, but cannot produce relative movement in the front-back and up-down directions, thereby limiting the movement of the card plate 200 in the front-back and up-down directions.

[0063] By using the combination of the oblong hole 220 and the limiting bolt 230, the clamping plate 200 can be limited in a single direction to prevent the clamping plate 200 from deviating greatly during movement, thereby ensuring that the clamping plate 200 can play a good clamping, positioning or releasing role on the clamping head 800 placed in the acupuncture hole 110.

[0064] In some embodiments, reference Figure 1 to Figure 2 The card plate 200 is provided with a limiting groove 240, and the limiting groove 240 and the acupuncture hole 110 are arranged correspondingly. The card plate 200 is provided with a plurality of protrusions 250 extending toward the limiting groove 240. In the first state, the protrusions 250 clamp the clamping head 800 to the acupuncture hole 110, and in the second state, the protrusions 250 move with the card plate 200 to release the clamping head 800 from the acupuncture hole 110.

[0065] Specifically, in this embodiment, a specific structure of a clamping plate 200 is provided, and a limiting groove 240 corresponding to the acupuncture hole 110 is opened on the clamping plate 200. The limiting groove 240 and the acupuncture hole 110 together constitute a channel for placing the clamping head 800. When the clamping head 800 is placed, the clamping head 800 passes through the limiting groove 240 and is then placed in the acupuncture hole 110. The number of the limiting grooves 240 can be consistent with the number of rows of the acupuncture holes 110, and the number of the limiting grooves 240 can also be consistent with the number of columns of the acupuncture holes 110. For example, assuming that the acupuncture plate 100 includes two rows and six columns of acupuncture holes 110, the number of the limiting grooves 240 can be set to two, corresponding to the number of rows of the acupuncture holes 110. At this time, one limiting groove 240 encircles six acupuncture holes 110 in a row, and the protrusions 250 on the card plate 200 are correspondingly set to each acupuncture hole 110 in the limiting grooves 240. For example, corresponding to each acupuncture hole 110, two relative protrusions 250 can be set on the card plate 200, that is, at this time, a total of twelve protrusions 250 are set in each limiting groove 240 of the card plate 200. When the card plate 200 and the acupuncture hole 110 are in the first state, the protrusions 250 can be used to clamp all the clamping heads 800 in each acupuncture hole 110. Alternatively, the number of the limiting grooves 240 can be set to six, corresponding to the number of columns of the acupuncture holes 110. In this case, one limiting groove 240 encircles two acupuncture holes 110 in a column, and the protrusions 250 on the card plate 200 and each acupuncture hole 110 in the limiting grooves 240 are set correspondingly. For example, corresponding to each acupuncture hole 110, two relative protrusions 250 can be set on the card plate 200, that is, at this time, a total of four protrusions 250 are set in each limiting groove 240 of the card plate 200. When the card plate 200 and the acupuncture hole 110 are in the first state, the protrusions 250 can be used to clamp all the clamping heads 800 in each acupuncture hole 110.

[0066] The limiting groove 240 on the card plate 200 adopts the above structure. Compared with the structure in which one limiting groove 240 is correspondingly arranged for one acupuncture hole 110, the structure provided in this embodiment is more conducive to improving the positioning accuracy of the card plate 200.

[0067] Furthermore, when the card plate 200 needs to be adjusted to the first state, the first driving unit 300 drives the card plate 200 to move until the protrusion 250 and each acupoint hole 110 are aligned to achieve clamping of the clamping head 800. When the card plate 200 needs to be adjusted to the second state, the first driving unit 300 drives the card plate 200 to move in the opposite direction until the edge of the card plate 200 and each acupoint hole 110 are aligned to achieve release of the clamping head 800.

[0068] In some embodiments, reference Figure 1A second driving unit 500 is provided on the side of the acupoint plate 100 away from the card plate 200, and the second driving unit 500 drives the acupoint plate 100 and the card plate 200 to move in the direction from the acupoint plate 100 to the card plate 200. Among them, the second driving unit 500 can be a driving cylinder. The driving cylinder is convenient for reversing movement, and the structure is simpler when used as a reciprocating drive. Specifically, when the head needs to disassemble or load the clamping head 800, the head and the acupoint plate 100 can move towards each other together, which is conducive to improving the efficiency of disassembling or loading the clamping head 800 of the head and shortening the time for disassembling or loading the clamping head 800 of the head.

[0069] In some embodiments, reference Figure 1 , Figure 3 and Figure 4 The second driving part 500 is connected to the acupuncture point plate 100 through the connecting assembly 600. The connecting assembly 600 includes a first connecting plate 610 and a second connecting plate 620. The first connecting plate 610 is slidably connected to the second driving part 500. The second connecting plate 620 is connected to one end of the first connecting plate 610 away from the second driving part 500. The acupuncture point plate 100 is connected to one end of the second connecting plate 620 away from the first connecting plate 610. The second driving part 500 is provided with a slide rail 510, and the first connecting plate 610 is provided with a slide groove 611. The slide rail 510 and the slide groove 611 can be matched and connected so that the first connecting plate 610 is slidably connected to the second driving part 500.

[0070] Specifically, the connection assembly 600 can provide support for the acupuncture plate 100, so that the second driving part 500 and the acupuncture plate 100 are in a stable structure as a whole, thereby improving the reliability and stability of the operation of the acupuncture plate 100. The second driving part 500 drives the first connecting plate 610 to slide along the slide rail 510, the first connecting plate 610 drives the second connecting plate 620 to move, and the second connecting plate 620 drives the acupuncture plate 100 to move toward or away from the machine head, so as to improve the efficiency of disassembling or loading the clamping head 800 of the machine head and shorten the time of disassembling or loading the clamping head 800 of the machine head.

[0071] Furthermore, the first connecting plate 610 is connected to the slide rail 510 of the second driving part 500 through the slide groove 611. The connection method is simple, the transmission is smooth and accurate, and the slide rail 510 provides a guide for the movement of the first connecting plate 610. The first connecting plate 610 can move linearly along the slide rail 510 to reduce shaking and swaying in other directions to improve the stability of the first connecting plate 610 during movement. More preferably, in actual application, lubricant can be sprayed onto the slide rail 510 to reduce the friction between the first connecting plate 610 and the slide rail 510, improve the control accuracy between the first connecting plate 610 and the slide rail 510, enhance the wear resistance of the first connecting plate 610 and the slide rail 510, and extend the service life of the first connecting plate 610 and the slide rail 510.

[0072] In some embodiments, the second driving unit 500 is provided with a position sensor (not shown in the figure) for monitoring the travel displacement of the first connecting plate 610. For example, a position sensor can be provided at each end of the slide rail 510, and the position sensor can be connected to the control center and the alarm. The position sensor is used to monitor the position signal of the first connecting plate 610 in real time and transmit the acquired position signal to the control center. When the first connecting plate 610 moves to the two ends of the slide rail 510, the control center controls the first connecting plate 610 to move in the opposite direction or stop moving, so as to prevent the first connecting plate 610 from continuing to move in the original direction and leaving the slide rail 510, thereby preventing the first connecting plate 610 from overtravel and causing damage to the equipment. If the first connecting plate 610 continues to move in the original direction due to the insensitive response of the control center, an alarm will be triggered to remind the staff to stop the equipment urgently to avoid safety accidents or equipment damage.

[0073] In some embodiments, reference Figure 1 The end of the second driving part 500 away from the acupuncture point plate 100 is connected to a mounting plate 700, and the mounting plate 700 is provided with a threaded hole to facilitate the connection of the automatic clamping head replacement device. Specifically, the automatic clamping head replacement device can be detachably connected through the mounting plate 700, and can be installed, replaced and adjusted according to different production requirements, so as to facilitate the adjustment of the position of each connection component or the addition of a component to meet the overall operation of the equipment.

[0074] Correspondingly, another embodiment of the present invention further provides an insertion machine, referring to Figures 5 and 6, the insertion machine includes the automatic clamping head replacement device in any of the above embodiments. In addition, the insertion machine also includes an insertion head device 900 and a positioning camera. The insertion head device 900 is provided with a plurality of clamping heads 800 for clamping electronic component materials and plugging the electronic component materials into the pin sockets preset on the circuit board. The insertion head device 900 is configured to be able to move toward or away from the automatic clamping head replacement device to achieve automatic replacement of the clamping head 800. The positioning camera is used to identify the position of the automatic clamping head replacement device so as to facilitate the insertion head device 900 to move toward the direction close to the automatic clamping head replacement device.

[0075] Specifically, four groups of clamping heads 800 can be set on both sides of the insertion head device 900. With such a structure, the insertion head device 900 has a compact structure and a large number of insertion heads. Each group of clamping heads 800 on the insertion head device 900 can be set to different models, so that electronic components with different structural forms can be inserted at the same time, thereby improving the insertion efficiency of the insertion machine and reducing the time cost of production.

[0076] More preferably, each clamping head 800 provided in the clamping head automatic replacement device may be marked with a corresponding number, and the position of the clamping head 800 that needs to be replaced may be accurately identified by a positioning camera.

[0077] In this embodiment, thanks to the improvement of the above-mentioned automatic clamping head replacement device, the insertion machine of this embodiment has the same technical effect as the above-mentioned automatic clamping head replacement device, which will not be repeated here.

[0078] It should be noted that the other contents of the automatic clamping head replacement device and the insertion machine disclosed in the utility model can be referred to the prior art and will not be described in detail here.

[0079] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
