Description

Technical Field

[0001] The utility model relates to the technical field of workpiece replacement, in particular to a quick-replacement chuck mechanism. Background Art

[0002] With the rapid development of electronic technology, the use of electronic products is becoming increasingly widespread. PCBs are key components of these products, and pre-insertion machines are processing equipment that pre-insert various electronic components into designated locations on PCBs. During the pre-insertion process, electronic components are typically transported one by one to a loading station. The pre-insertion machine then clamps the components onto the PCB using a chuck.

[0003] To accommodate more electronic components, most pre-insertion machines on the market are equipped with two to four chucks of different specifications. However, since multiple electronic components often need to be pre-inserted on PCBs, if the size or gripping method of these components does not match the chucks installed on the pre-insertion machine, the machine must be stopped for manual chuck replacement, ultimately resulting in low production efficiency. Therefore, a quick chuck replacement mechanism is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a quick-change chuck mechanism, which can quickly replace the chuck without stopping the machine during production, thereby improving the compatibility and production efficiency of the equipment.

[0005] A quick-change chuck mechanism comprises a tool magazine unit and a pre-insertion machine pressure head unit; the tool magazine unit comprises a plurality of chuck limit blocks, a plurality of spacer blocks, and a plurality of chucks; the plurality of chuck limit blocks are arranged at intervals; the plurality of spacer blocks are respectively arranged between every two adjacent chuck limit blocks, and at least one end of the plurality of chuck limit blocks respectively extends out of the spacer blocks, so that at least one chuck storage slot is formed between every two adjacent chuck limit blocks and the spacer blocks; in each of the chuck storage slots, the facing sides of the two adjacent chuck limit blocks are respectively provided with a first limiting portion, and the spacer block is provided with a first Magnetic part, the first magnetic part is used to provide adsorption force to adsorb the chuck; each chuck is slidably arranged in a chuck storage slot, wherein a second limit part is provided on both sides of each chuck, and the second limit part slides with the first limit part; the pre-insertion machine ram unit is installed on the XYZ axis unit, and the XYZ axis unit can drive the pre-insertion machine ram unit to move along the X, Y and Z directions; the pre-insertion machine ram unit includes a chuck connecting seat, and a second magnetic part arranged on the chuck connecting seat; the second magnetic part is used to provide adsorption force to adsorb the chuck.

[0006] The quick-change chuck mechanism of the present invention can quickly replace chucks and improve work efficiency. The tool magazine unit is used to store a plurality of chucks, wherein a plurality of chuck storage slots are formed by the design of a plurality of chuck limit blocks and a plurality of spacers, so that a chuck can be stored in each chuck storage slot. The outside of each chuck storage slot is open, and the chuck can be placed into the chuck storage slot from the outside of the chuck storage slot, and the second limit portion on the chuck cooperates with the first limit portion on the chuck limit block to position and slide in the chuck storage slot. When the chuck slides to the inner position of the chuck storage slot, that is, close to the spacer position, the first magnetic member provided on the spacer provides an adsorption force to adsorb the chuck. The chuck connecting seat of the pre-insertion machine ram unit attracts the top of the chuck through the second magnetic part. When the chuck attracted on the chuck connecting seat needs to be replaced, the pre-insertion machine ram unit is moved along the X, Y, and Z axis directions to the outside of the chuck storage slot where no chuck is stored in the tool magazine unit by using the XYZ axis unit, and further moved so that the second limiting part of the chuck cooperates with the first limiting part, and slides on the chuck storage slot to the position of the spacer block so that the first magnetic part attracts the chuck; then the pre-insertion machine ram unit is moved upward by using the XYZ axis unit, and since the second limiting part cooperates with the first limiting part, the chuck is restricted from moving upward, thereby separating the chuck from the chuck connecting seat, and completing the chuck unloading activity. Then, when the required chuck needs to be assembled, the pre-insertion machine press head unit is moved to the top of the required chuck using the XYZ axis unit, so that the second magnetic part on the chuck connecting seat adsorbs the top of the chuck and moves toward the outside of the chuck storage slot until the chuck is completely out of the chuck storage slot of the tool magazine, thereby completing the replacement of the chuck.

[0007] The quick-change chuck mechanism of the present invention, driven by the XYZ axis unit, can move the pre-insertion machine pressure head unit to the tool magazine unit for quick chuck replacement, thereby solving the problem in related technologies of slow replacement speed caused by the need for manual disassembly and replacement of chucks, improving equipment compatibility and simplicity of mechanism, and achieving the effect of improving production.

[0008] Furthermore, the first limiting portion is a limiting protrusion, which extends along the two ends of the chuck limiting block on the side surface of the chuck limiting block; the second limiting portion is a limiting groove adapted to the limiting protrusion. In each of the chuck storage slots, limiting protrusions extending along the two ends of the chuck limiting blocks are respectively designed on the facing sides of the two adjacent chuck limiting blocks, and limiting grooves are respectively designed on both sides of the chuck, so that the limiting grooves on both sides of the chuck can be positioned and slid on the two limiting protrusions on the two adjacent chuck limiting blocks. The above situation does not represent a structural limitation on the first limiting portion and the second limiting portion. Those skilled in the art can also make conventional designs for the first limiting portion and the second limiting portion according to actual conditions.

Through the design of the above structure, two chuck storage slots are formed at the two ends of each spacer, which can be used to store chucks respectively, and are particularly suitable for storing paired chucks; through the design of the cover plate, the plurality of chuck limit blocks and the plurality of spacers are fixed together to improve the structural stability.

[0010] Furthermore, the tool magazine unit includes a concave support base; the outermost two of the plurality of chuck stoppers are fixedly mounted on top of the support base on either side. This structural design allows the chuck storage slot to be located within the concave cavity of the support base, providing ample space for storing and replacing chucks.

[0011] Furthermore, the tool magazine unit further comprises support legs, which are arranged at the bottom of the support base to support the above structure on the ground or other structures.

[0012] Furthermore, optical fiber sensors are provided at both ends of each spacer, and are used to detect whether there is a chuck in the chuck storage slot, so that when replacing a chuck, the chuck can be placed in a chuck storage slot without a chuck.

[0013] Furthermore, the quick-change chuck mechanism also includes a control unit; the control unit is electrically connected to the XYZ axis unit, and the control unit can control the XYZ axis unit to drive the pre-insertion machine ram unit to move along the X, Y, and Z directions; the control unit is wirelessly connected to the optical fiber sensor, and when the optical fiber sensor detects that there is no chuck in the chuck storage slot, a feedback signal is sent to the control unit, allowing the control unit to control the XYZ axis unit to drive the pre-insertion machine ram unit to carry the chuck to the chuck storage slot for storage; when the optical fiber sensor detects that there is a chuck in the chuck storage slot, a feedback signal is sent to the control unit, allowing the control unit to control the XYZ axis unit to drive the pre-insertion machine ram unit to move to the chuck storage slot to remove the chuck.

In a preferred embodiment, the chuck connection base is generally provided with two, namely the first chuck connection base and the second chuck connection base, respectively connected to two chucks, and the two chucks are used to clamp electronic components or other products.

[0017] Furthermore, the chuck connecting seat includes a first chuck connecting seat and a second chuck connecting seat; the first chuck connecting seat and the second chuck connecting seat are both provided with the second magnetic part; the pre-insertion machine press head unit also includes a rotating connecting seat, a screw receiving seat, a bidirectional screw, and a screw driving assembly; the rotating connecting seat is rotatably set on the XYZ axis unit; the top of the screw receiving seat is fixedly set on the rotating connecting seat, and two receiving plates are spaced apart on both sides of the bottom of the screw receiving seat; the two ends of the bidirectional screw are rotatably set on the two receiving plates respectively; the bidirectional screw is respectively provided with a first thread and a second thread opposite to the first thread; the first chuck connecting seat and the second chuck connecting seat respectively pass through the bidirectional screw, and are respectively threadedly connected to the first thread and the second thread; the screw driving assembly is used to drive the bidirectional screw to rotate in both directions, so that the first chuck connecting seat and the second chuck connecting seat are closer to or farther away from each other.

[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] Furthermore, the terms "first," "second," "third," etc., in the specification and claims are used solely for descriptive purposes to distinguish between identical technical features. They are not to be construed as indicating or implying relative importance, or as implicitly specifying the number of technical features, nor do they necessarily describe a sequential or chronological order. The terms are interchangeable where appropriate. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one of those features.

[0026] Similarly, the term "connected" used in the specification and claims should not be construed as limited to direct connections. Thus, the expression "device A is connected to device B" should not be limited to devices or systems in which device A is directly connected to device B. Rather, it means that there is a path between device A and device B, which may include other devices or tools.

[0027] Example 1

[0028] PCBs often require pre-insertion of multiple electronic components. Pre-insertion machines are processing equipment that pre-insert various electronic components into designated locations on PCBs. Conventional technology uses chucks installed on pre-insertion machines to clamp electronic components. However, due to variations in the types, sizes, and clamping methods of the electronic components required on PCBs, these chucks are not suitable for a wide range of electronic components. Manual replacement of chucks is often required to clamp different electronic components, ultimately leading to low production efficiency.

[0029] Therefore, this embodiment provides a quick chuck replacement mechanism to achieve quick chuck replacement and improve production efficiency.

[0030] A quick-change chuck mechanism of this embodiment is shown in Figure 1 , including a tool magazine unit 1 and a pre-insertion machine head unit 2. By moving the pre-insertion machine head unit 2 to the tool magazine unit 1 to replace the chuck, the problem of slow chuck replacement is solved, equipment compatibility, structural simplicity, and the effect of improving production are achieved.

[0031] See also Figure 1 and Figure 2The tool magazine unit 1 is used to store a plurality of chucks 13. The chucks can be of different sizes or models, so as to be equipped with a variety of chucks to meet the clamping needs of different electronic components. Figure 2 The tool magazine unit 1 includes a number of chuck limit blocks 11, a number of spacers 12, and a number of chucks 13 (in order to facilitate viewing the structure of the tool magazine unit 1, Figure 2 Only one chuck 13 is retained in the chuck. A plurality of chuck limiting blocks 11 are arranged at intervals, and a plurality of spacers 12 are respectively arranged between every two adjacent chuck limiting blocks 11, and at least one end of each of the chuck limiting blocks 11 extends out of the spacer 12, so that at least one chuck storage slot 110 is enclosed between every two adjacent chuck limiting blocks 11 and the spacer 12. In each chuck storage slot 110, a first limiting portion 111 is respectively provided on the facing side surfaces of two adjacent chuck limiting blocks 11, and the spacer 12 is provided with a first magnetic member 14, which is used to provide an adsorption force to adsorb the chuck 13. Each chuck 13 is slidably arranged in a corresponding chuck storage slot 110, wherein a second limiting portion 131 is respectively provided on both sides of each chuck 13, and the second limiting portion 131 slidably cooperates with the first limiting portion 111 to enable the chuck 13 to slide in the chuck storage slot 110 for easy storage or removal of the chuck. The tool magazine unit 1 of this embodiment forms a plurality of chuck storage slots 110 by designing a plurality of chuck limit blocks 11 and a plurality of spacer blocks 12, so that a chuck 13 can be stored in each chuck storage slot 110; and the outer side of each chuck storage slot 110 (i.e., between the ends of two adjacent chuck limit blocks 11) is an open opening, and the chuck 13 can be placed into the chuck storage slot 110 from the outside of the chuck storage slot 110, and positioned and slid in the chuck storage slot 110 by cooperation between the second limit portion 131 on the chuck 13 and the first limit portion 111 on the chuck limit block 11. When the chuck 13 slides to the inner position of the chuck storage slot 110, that is, close to the spacer block 12, the first magnetic member 14 provided on the spacer block 12 provides adsorption force to adsorb the chuck for stable storage.

[0032] See also Figure 1 and Figure 3 The pre-insertion machine head unit 2 is installed on the XYZ axis unit 3, and the XYZ axis unit 3 can drive the pre-insertion machine head unit 2 to move along the X, Y, and Z directions, so as to move the pre-insertion machine head unit 2 to the tool magazine unit 1 or other locations. Figure 3 , those skilled in the art will readily appreciate that the three directions X, Y, and Z refer to the left-right direction, the front-back direction, and the up-down direction, respectively, and that the three directions are perpendicular to each other. Figure 3 and Figure 4The pre-insertion machine ram unit 2 includes a chuck connection base 21 and a second magnetic member (not shown) disposed on the chuck connection base 21. The second magnetic member is used to provide an attractive force to attract the chuck 3. In this embodiment, the second magnetic member is disposed within the chuck connection base 21. When the chuck connection base 21 is close to the top of the chuck 13, the chuck 13 is magnetically attracted to the chuck connection base 21, allowing the chuck 13 to be assembled on the chuck connection base 21.

[0033] The quick-change chuck mechanism of this embodiment, driven by the XYZ axis unit 3, can accurately move the pre-insertion machine head unit 2 to the tool magazine unit 1 to quickly replace the chuck, solving the problem of slow replacement speed caused by the need for manual disassembly and replacement of the chuck 13 in the related art, improving equipment compatibility, simplicity of mechanism, and achieving the effect of improving production. When the chuck connecting seat 21 of the pre-insertion machine head unit 2 needs to be assembled with the chuck 13, the pre-insertion machine head unit 2 is moved to the top of the chuck 13 to be assembled in the tool magazine unit 1 by using the XYZ axis unit 3, and approaches the top of the chuck 13 to be assembled, so that the chuck connecting seat 21 adsorbs the assembled chuck 13 through the second magnetic part, and further moves the chuck connecting seat 21 to the outside of the chuck storage slot 110 where the chuck 13 is located by using the XYZ axis unit 3 until it is out of the chuck storage slot 110, completing the assembly. When the chuck needs to be replaced, the XYZ axis unit 3 is used to move the chuck connecting seat 21 to the outside of the chuck storage slot 110 corresponding to the chuck 13, and further moved so that the second limiting portion 131 of the chuck 13 cooperates with the first limiting portion 111, and slides in the chuck storage slot 110 to the position of the spacer 12, so that the first magnetic member 14 adsorbs the chuck 13, and then the XYZ axis unit 3 is used to move the pre-insertion machine press head unit 2 upward. Since the second limiting portion 131 cooperates with the first limiting portion 111, the chuck 13 is restricted from moving upward, thereby separating the chuck 13 from the chuck connecting seat 21, completing the unloading activity of the chuck 13. When other chucks need to be replaced, the XYZ axis unit 3 is used to move the pre-insertion machine press head unit 2 to the top of the chuck 13 to be replaced in the tool magazine unit 1, and the above chuck assembly steps are repeated to complete the replacement.

[0034] In this embodiment, in order to meet the storage needs of chucks of different models or sizes, chuck storage slots 110 of different sizes can be formed by adjusting the distance between two adjacent chuck limit blocks, thereby meeting the storage needs of multiple chucks.

[0035] In this example, see Figure 2The tool magazine unit 1 further includes a cover plate 15; a plurality of chuck stoppers 11 are fixedly disposed at intervals on the bottom of the cover plate 15, with the ends of the chuck stoppers 11 extending out of the sides of the cover plate 15. In this embodiment, the cover plate 15 is in the shape of an elongated plate, with the ends of the cover plate 15 perpendicular to the ends of the chuck stoppers 11. The chuck stoppers 11 are parallel to each other, and the middle portions of the chuck stoppers 11 are fixed to the bottom of the cover plate 15 in sequence from one end to the other. A plurality of spacers 12 are fixedly mounted on the bottom of the cover plate 15 and are disposed between every two adjacent chuck limiting blocks 12. The two ends of each spacer 12 slightly extend out of the two sides of the cover plate 15, but do not extend out of the two ends of the chuck limiting block 11, so that two chuck storage slots 110 located at the two ends of the spacer 12 (located on both sides of the cover plate 15) are enclosed between every two adjacent chuck limiting blocks 11 and the spacer 12; a first magnetic member 14 is fixedly mounted at each end of each spacer 12. Through the design of the above structure, this embodiment forms two chuck storage slots 110 at both ends of each spacer 12, which can be used to store chucks respectively, and are particularly suitable for storing pairs of chucks 13; the chuck limiting blocks 11 and the spacers 12 are fixed together by the cover plate 15, thereby improving the structural stability of the tool magazine unit.

[0036] In this example, see Figure 2 In each chuck storage slot 110, the first limiting portions 111 designed on the facing side surfaces of two adjacent chuck limiting blocks 11 are both limiting protrusions, which extend along the two ends of the chuck limiting block on the side surface of the chuck limiting block 11; the second limiting portions 131 on both sides of each chuck 13 are limiting grooves adapted to the limiting protrusions, so that the limiting grooves on both sides of the chuck 13 can be positioned and slid on the two limiting protrusions on the two adjacent chuck limiting blocks 11, thereby achieving sliding in the chuck storage slot 110. The above situation does not represent a structural limitation on the first limiting portion 111 and the second limiting portion 131. Those skilled in the art can also make conventional designs for the first limiting portion 111 and the second limiting portion 131 according to actual conditions, such as exchanging the structures of the limiting protrusion and the limiting groove, or other conventional structures.

[0037] In this embodiment, optical fiber sensors 16 are provided at both ends of each spacer block 12. The optical fiber sensors 16 are used to detect whether there is a chuck 13 in the chuck storage slot 110, so that when the chuck 13 is replaced, the chuck 13 can be placed in the chuck storage slot 110 without a chuck.

[0038] In this embodiment, the quick-change chuck mechanism of this embodiment further includes a control unit (not shown); the control unit is electrically connected to the XYZ axis unit 3, and the control unit can control the XYZ axis unit 3 to drive the pre-insertion machine press head unit 2 to move along the X, Y, and Z directions; the control unit is wirelessly connected to the optical fiber sensor 16 respectively, and when the optical fiber sensor 16 detects that there is no chuck in the chuck storage slot 110, a feedback signal is sent to the control unit, allowing the control unit to control the XYZ axis unit 3 to drive the pre-insertion machine press head unit 2 to carry the chuck 13 to move to the chuck storage slot 110 for storage; when the optical fiber sensor 16 detects that there is a chuck in the chuck storage slot 110, a feedback signal is sent to the control unit, allowing the control unit to control the XYZ axis unit 3 to drive the pre-insertion machine press head unit 2 to move to the chuck storage slot 110 to remove the chuck 13. The control unit performs corresponding control, thereby improving the working efficiency of the quick-change chuck mechanism of this embodiment.

[0039] In this example, see Figure 2 The tool magazine unit 1 also includes a support seat 17, which is concave. A number of chuck limit blocks 11 are fixed to the bottom of the cover plate 13, and a number of chuck limit blocks 11 are respectively provided at both ends of the bottom of the cover plate 15; the two chuck limit blocks 11 located on the outermost sides of the chuck limit blocks 11 (i.e., the two chuck limit blocks 11 located at both ends of the bottom of the cover plate 15) are respectively fixed on the top of both sides of the support seat 17, so that the chuck storage slot 110 is located on the concave cavity of the support seat 17, providing sufficient space for storing chucks or replacing chucks. In this embodiment, the tool magazine unit 1 also includes a support leg 18, which is provided at the bottom of the support seat 1. To support the above structure on the ground or other structures. A vertical DIN rail 181 is also provided on the outer side of the support leg 18, and a number of amplifiers 19 are provided on the DIN rail. The amplifiers 19 are respectively used to amplify the signals received by the optical fiber sensor 16.

[0040] In this example, see Figure 4 and Figure 5The bottom of the chuck connecting seat 21 is provided with a first positioning portion 211; the tops of several chucks 13 are respectively provided with second positioning portions 132, and the first positioning portion 211 is adapted to the second positioning portion 132. In this embodiment, the first positioning portion 211 is a positioning pin protruding downward from the bottom of the chuck connecting seat 21; the second positioning portion 132 is a positioning groove adapted to the positioning pin. By designing a positioning pin at the bottom of the chuck connecting seat 21 and a positioning groove at the top of the chuck 13, when the second magnetic part of the chuck connecting seat 21 adsorbs the chuck 13, the positioning pin and the positioning groove are used to position the chuck so that the chuck is stably adsorbed on the chuck connecting seat. And in the process of driving the chuck 13 to move toward the outside of the chuck storage slot 110, the restriction of the positioning pin is used to drive the chuck 13 away from the spacer 12 and break away from the adsorption of the first magnetic part 14, so that the chuck 13 can be smoothly taken out.

[0041] There are usually two clamping connectors 21 to assemble two clamping heads 13, which are used to clamp electronic components or other products. Figure 4 and Figure 5 The chuck connecting seat 21 includes a first chuck connecting seat 212 and a second chuck connecting seat 213; a second magnetic member is provided inside the first chuck connecting seat 212 and the second chuck connecting seat 213, and a positioning pin (first positioning portion 211) is provided at the bottom of the first chuck connecting seat 212 and the second chuck connecting seat 213.

[0042] The pre-insertion machine pressure head unit 2 of this embodiment is shown in FIG. Figure 3-Figure 5It also includes a rotating connection seat 22, a screw rod receiving seat 23, a bidirectional screw rod 24, and a screw rod drive assembly 25. The rotating connection seat 22 is rotatably set on the XYZ axis unit, so that the rotating connection seat 22 can not only move in the XYZ axis direction, but also rotate to adjust the angle, thereby improving flexibility. The top of the screw rod receiving seat 23 is fixedly set on the rotating connection seat 22, and two receiving plates 231 are spaced apart on both sides of the bottom of the screw rod receiving seat 23; the two ends of the bidirectional screw rod 24 are rotatably set on the two receiving plates 231 respectively; the bidirectional screw rod 24 is respectively provided with a first thread and a second thread opposite to the first thread; the first chuck connection seat 212 and the second chuck connection seat 213 respectively pass through the bidirectional screw rod 24 and are respectively threadedly connected to the first thread and the second thread, so that when the bidirectional screw rod 24 rotates forward or reverse, the first chuck connection seat 212 and the second chuck connection seat 213 can be moved closer to or away from each other under the action of the first thread and the second thread. In order to ensure stable movement of the first chuck connecting seat 212 and the second chuck connecting seat 213, a slide bar 232 is fixedly provided in the middle of the bottom of the screw rod receiving seat 23. The tops of the first chuck connecting seat 212 and the second chuck connecting seat 213 are also slidably provided on the slide bar 232. The screw rod driving assembly 25 is used to drive the bidirectional screw rod 24 to rotate forward or reverse. In this embodiment, it includes a motor 251 and a belt transmission member 252. The belt transmission member 252 is respectively connected to the output shaft of the motor 251 and the bidirectional screw rod 24. The motor 251 can rotate in both directions to drive the bidirectional screw rod 24 to rotate forward or reverse through the belt transmission member 252, so that the first chuck connecting seat 212 and the second chuck connecting seat 213 are moved closer to or away from each other, thereby allowing the two chucks of the first chuck connecting seat 212 and the second chuck connecting seat 213 to clamp or release the electronic components. In addition, by adjusting the distance between the first chuck connection seat 212 and the second chuck connection seat 213 , flexibility can be improved and mutual influence can be avoided when the first chuck connection seat 212 and the second chuck connection seat 213 are respectively disassembled or assembled into the chuck 13 .

[0043] In this embodiment, the XYZ axis unit 3 may be a conventional gantry structure for realizing XYZ axis motion, or other structures capable of realizing XYZ axis motion, which will not be described in detail here.

[0044] The working principle of the quick-change chuck mechanism of this embodiment is as follows:

[0045] Taking the initial state where the first chuck connecting seat 212 and the second chuck connecting seat 213 are respectively equipped with chucks 13 as an example, when the chuck 13 needs to be switched, the XYZ axis unit 3 is used to drive the pre-insertion machine press head unit 2 to move to the vicinity of the tool magazine unit 1, so that the chuck 13 connected to the first chuck connecting seat 212 is facing the chuck storage slot 110 from the outside of the chuck storage slot 110, so that the second limiting portions 131 (limiting grooves) on both sides of the chuck 13 are respectively aligned with the first limiting portions 111 (limiting protrusions) of the two chuck limiting blocks 11, and the chuck 13 is moved to the XYZ axis unit 3. Under the driving action of the chuck 13, the chuck 13 moves into the chuck storage slot 110, so that the chuck 13 is adsorbed on the first magnetic part 14, and then the pre-insertion machine press head unit 2 is moved upward under the driving action of the XYZ axis unit 3. Due to the action of the first limiting part 111 and the second limiting part 131, the chuck 13 is restricted from moving upward, and the chuck 13 begins to separate from the first chuck connecting seat 212 until the first positioning part 211 (positioning pin) of the first chuck connecting seat 212 is completely separated from the clamp block 13. At this point, the chuck 13 on the first chuck connecting seat 212 is completely unloaded. As for the second chuck connecting seat 213, the rotating connecting seat 22 can be driven to rotate to adjust the angle, and under the adjustment action of the XYZ axis unit 3, the distance between the first chuck connecting seat 212 and the second chuck connecting seat 213 can be adjusted, and then the chuck 13 on the second chuck connecting seat 213 is moved to the outside of the corresponding chuck storage groove 110 for the above-mentioned unloading to prevent the first chuck connecting seat 212 from affecting the second chuck connecting seat 213. Similarly, the same adjustment can be made during the chuck unloading process of the above-mentioned first chuck connecting seat 212.

[0046] When it is necessary to switch the assembly chuck, the XYZ axis unit 3 is used to drive the pre-insertion machine press head unit 2 to move to the vicinity of the tool magazine unit 1, so that the first chuck connecting seat 212 moves to the top of the chuck 13 to be replaced, and the first positioning portion 211 (positioning pin) of the first chuck connecting seat 212 is inserted into the second positioning portion 132 (positioning groove) of the clamping block 13, and the chuck is adsorbed by the second magnetic member; under the driving action of the XYZ axis unit 3, the chuck 13 is moved to the outside of the chuck storage slot 110 until the chuck 13 is separated from the chuck storage slot 110. At this point, the replacement of the chuck 13 on the first chuck connecting seat 212 is completed. The assembly of the second chuck connecting seat 213 can also be achieved by driving the rotary connecting seat 22 to rotate to adjust the angle, and under the adjustment action of the XYZ axis unit 3, and adjusting the distance between the first chuck connecting seat 212 and the second chuck connecting seat 213, and then moving the second chuck connecting seat 213 to the top of the chuck to be replaced, and performing the corresponding operation.
