In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] This embodiment provides an equivariable distance adjustment component, such as Figure 1 and Figure 2As shown, it includes a base 100, an adjustment plate 200, an adjustment seat 300 and a driving component 400, wherein the base 100 is used as a mounting base for mounting and carrying other components; the adjustment plate 200 is slidably connected to the base 100 along the Y direction, and a driving groove 210 is provided on one side of the adjustment plate 200, and both ends of the driving groove 210 along the Z direction are through-set; there are multiple adjustment seats 300, and the multiple adjustment seats 300 are arranged along the X direction and slidably connected to the base 100, and the adjustment seats 300 are connected to the adjustment plate 200 through an adjustment mechanism; the driving component 400 is arranged on the base 100, and a floating driving head 500 is fixed at the driving end of the driving component 400, and the floating driving head 500 is movably plugged into the driving groove 210 along the Z direction, and the driving component 400 is used to drive the adjustment plate 200 to move along the Y direction, so as to drive the multiple adjustment seats 300 to gather or disperse at equal distances along the X direction through the adjustment mechanism.

[0030] The equi-variable-distance adjustment assembly provided in this embodiment needs to be assembled by slidingly connecting the adjustment plate 200 to the base 100 along the Y direction, slidingly connecting the multiple adjustment seats 300 to the base 100 along the X direction, and fixing the driving component 400 to the base 100, wherein the multiple adjustment seats 300 and the base 100 are connected via an adjustment mechanism, and the floating driving head 500 of the driving component 400 is movably connected to the driving groove 210 on one side of the adjustment plate 200 along the Z direction.

[0031] On the one hand, both ends of the driving groove 210 in the Z direction are through-set, and the connection area between the floating driving head 500 and the driving end of the driving component 400 extends into the notch of the driving groove 210. Both ends of the floating driving head 500 in the Z direction do not interfere with the two end surfaces of the driving groove 210 in the Z direction, that is, the floating driving head 500 can pass through the driving groove 210 in the Z direction, thereby completing the connection between the driving component 400 and the base 100, the connection between the adjustment plate 200 and the base 100, the connection between the adjustment seat 300 and the base 100, and the connection between the adjustment plate 200 and the adjustment seat 300. After the multiple positions of the adjustment mechanism are installed and connected, in the Z direction, there is an overlapping area between the floating drive head 500 and the drive slot 210, so that the Z-direction plug-in fit between the two can be achieved. Under the drive of the driving component 400, the plug-in area between the floating drive head 500 and the drive slot 210 can apply a driving force to the drive slot 210, driving the adjustment plate 200 to reciprocate along the Y direction, thereby reducing the Z-direction position accuracy requirements for the adjustment plate 200, the adjustment seat 300 and the drive component 400 installed on the base 100, reducing the assembly difficulty and processing costs. On the other hand, the floating drive head 500 and the drive slot 210 are movably plugged in. During disassembly or assembly, the floating drive head 500 only needs to be inserted into the drive slot 210 along the Z direction from the through holes at both ends of the drive slot 210. The disassembly or assembly is relatively convenient. The adjustment plate 200 is detachably connected to the base 100, and different types of adjustment plates 200 can be replaced according to the required spacing adjustment range, thereby improving the convenience of disassembly or assembly of the equal-variable spacing adjustment component, reducing maintenance costs and increasing its scope of application.

[0032] After assembly is completed, the floating drive head 500 can be driven to move along the Y direction by the driving component 400, and the floating drive head 500 can drive the adjustment plate 200 to move along the Y direction through the driving groove 210. Under the drive of the adjustment mechanism and the action of the X-direction sliding limit, multiple adjustment seats 300 can be gathered toward the middle or dispersed to both ends at equal intervals along the X direction, thereby realizing equal variable distance adjustment of multiple adjustment seats 300.

[0033] Specifically, this embodiment also provides a multi-claw equal-distance device, such as Figure 1 and Figure 2As shown, it includes a plurality of clamping jaws 700 and the above-mentioned equal-variable-distance adjustment component, and the plurality of clamping jaws 700 are fixedly arranged one by one in the plurality of adjustment seats 300 in the equal-variable-distance adjustment component. When in use, the spacing between the plurality of adjustment seats 300 can be adjusted by the adjustment mechanism according to the spacing between the material trays and fixtures to be clamped, and the spacing of the plurality of clamping jaws 700 can be adjusted accordingly, so that they can correspond one by one with an equal number of material trays or fixtures, thereby realizing the clamping and transportation of a plurality of material trays or fixtures, improving the transportation efficiency and equipment capacity, and the spacing of the plurality of clamping jaws 700 is adjustable, which can be suitable for the clamping and transportation of material trays or fixtures with different spacings, and has a wide range of applications and strong functionality. At the same time, the multi-jaw equal-variable-distance device adopts the above-mentioned equal-variable-distance adjustment component, and the floating plug-in of the floating drive head 500 and the drive slot 210 can reduce the Z-direction position accuracy requirements for the adjustment plate 200, the adjustment seat 300 and the drive component 400 installed on the base 100, thereby reducing the assembly difficulty and processing cost.

[0034] Of course, in some other embodiments, other adjustment members that need to adjust the spacing at equal intervals, such as suction nozzles, etc., can be connected to the adjustment seat 300 of the equal variable distance adjustment component as needed, and are not limited to the above-mentioned clamping jaws 700.

[0035] Optionally, in this embodiment, if Figure 2 As shown, the driving groove 210 includes a first groove section 211 and a second groove section 212 along the groove depth direction, and the groove width of the first groove section 211 is smaller than that of the second groove section 212. The floating driving head 500 matches the driving groove 210, and includes a first floating section 510 and a second floating section 520 along the direction away from the driving plate of the driving component 400, and the width of the first floating section 510 is smaller than that of the second floating section 520, wherein the first floating section 510 is plugged into the first groove section 211, and the second floating section 520 is plugged into the second groove section 212; when the driving groove 210 is located at one end side wall of the adjustment plate 200 in the X direction, when the floating driving head 500 is plugged into the driving groove 210 in the Z direction, the width of the driving groove 210 The degree direction is consistent with the Y direction, the groove side walls on both sides of the Y direction can limit the floating drive head 500 in the Y direction, and the groove side walls on both sides of the X direction in the area where the second groove section 212 extends out of the first groove section 211 along the Y direction can limit the second floating section 520 in the X direction, so that after the floating drive head 500 is inserted into the drive groove 210, it can only move relatively along the Z direction, and cannot move relatively along the X direction and the Y direction, which correspondingly improves the stability of the floating drive head 500 being movably inserted into the drive groove 210, thereby ensuring the driving stability of the drive component 400 on the adjustment plate 200.

[0036] Similarly, when the driving groove 210 is located at one end side wall of the adjustment plate 200 in the Y direction, the groove side walls on both sides of the driving groove 210 in the X direction can limit the floating driving head 500 in the X direction, and the groove side walls on both sides of the Y direction in the area where the second groove section 212 extends out of the first groove section 211 in the X direction can limit the second floating section 520 in the Y direction, so that after the floating driving head 500 is inserted into the driving groove 210, it can only move relatively in the Z direction, and cannot move relatively in the X and Y directions, which correspondingly improves the stability of the floating driving head 500 that is movably inserted into the driving groove 210, thereby ensuring the driving stability of the adjustment plate 200 by the driving component 400.

[0037] Specifically, in this embodiment, the driving groove 210 is located on one end side wall of the adjustment plate 200 in the Y direction, and a threaded hole extending along the Y direction is provided on the side wall of the base 100 corresponding to the notch of the driving groove 210; the driving end of the driving component 400 is a telescopic driving end and the telescopic direction is consistent with the Y direction, and the connecting part 410 of the driving component 400 is provided with a connecting hole 411 extending along the Y direction and corresponding to the threaded hole; the equi-variable adjustment component also includes a connecting screw, which passes through the connecting hole 411 and is screwed into the threaded hole.

[0038] Compared with the existing adjustment assembly, when part of the driving component 400 drives the adjustment plate 200 to move, the connecting parts of the driving component 400 and the base 100 are subjected to a larger torque, which makes the connecting parts easily deformed completely and the connection stability of the driving component 400 is poor; in the equivariable distance adjustment assembly of the present application, the axial directions of the threaded hole, the connecting hole 411 and the connecting screw all extend along the Y direction. When the spacing of the adjustment seat 300 needs to be adjusted, the driving end of the driving component 400 applies a driving force along the Y direction to the adjustment plate 200 through the floating driving head 500. Accordingly, the driving component 400 applies a reverse reaction force to the base 100 through the connecting screw. Since the direction of the reaction force is consistent with the axial direction of the connecting screw, the connecting screw is only subjected to axial tension or extrusion force, and the connection strength and stability of the connecting screw are relatively high, which ensures the stability of the driving component 400 connected to the base 100 and ensures its adjustment drive of the adjustment plate 200.

[0039] Specifically, the driving component 400 may be a double-acting cylinder.

[0040] In this embodiment, Figure 3 As shown, the adjustment mechanism can be specifically in the following form: the adjustment plate 200 is provided with a plurality of adjustment grooves 220 which are radially arranged and spaced apart along the X direction, and at any X-direction dividing line of the adjustment grooves 220, the distance between each two adjacent adjustment grooves 220 is equal; each adjustment seat 300 is provided with a plug-in protrusion 310, and the plurality of plug-in protrusions 310 are plugged into the plurality of adjustment grooves 220 one by one along the Z direction to form an adjustment mechanism.

[0041] In the X-direction dividing line of each adjustment groove 220, the spacing between any two adjacent ones is equal, and the spacing gradually changes along the extension direction of the adjustment groove 220; initially, the plug-in protrusions 310 of each adjustment seat 300 are plugged into the multiple adjustment grooves 220 one by one, and the multiple plug-in protrusions 310 are located on the same X-direction dividing line of each adjustment groove 220, and each adjustment seat 300 is arranged at equal intervals along the X direction; each plug-in protrusion 310 can only be inserted along the X direction under the limiting action of the X-direction sliding mechanism with the base 100 When the distance between two adjacent adjustment seats 300 needs to be reduced, the driving component 400 drives the adjustment plate 200 to move along the Y direction, so that the gathered ends of each adjustment groove 220 move toward the plug-in protrusion 310. Accordingly, the plug-in protrusion 310 and the gathered ends of each adjustment groove 220 slide toward each other and gather toward the middle along the X direction under the gathering effect of the adjustment groove 220. The X-direction spacing of each plug-in protrusion 310 decreases and maintains an equal spacing, and the adjustment seat 300 realizes the X-direction equal variable spacing reduction. Similarly, the driving component 400 drives the adjustment plate 200 to move in the reverse direction, and the base shell realizes the X-direction equal variable spacing of each adjustment seat 300. The structure is simple, the adjustment is convenient, and the equal variable spacing adjustment consistency is high.

[0042] Specifically, in this embodiment, Figure 3 As shown, the plug-in protrusion 310 is a roller, which is pivotally connected to the adjustment seat 300 and the pivoting direction is consistent with the groove depth direction of the adjustment groove 220. During the distance adjustment process, when the roller slides relative to the adjustment groove 220, when the outer circumferential surface of the roller contacts the groove side wall of the adjustment groove 220, the roller is forced to rotate, so that there is rolling friction between the roller and the groove side wall of the adjustment groove 220, thereby reducing the friction resistance between the roller and the adjustment groove 220, and on the basis of ensuring that the adjustment groove 220 plays a guiding role on the roller, the adjustment smoothness is improved and the driving load of the driving component 400 is reduced.

[0043] In this embodiment, Figure 3As shown, along the X direction, among the multiple adjustment slots 220, the one located in the middle serves as the center slot 221 extending along the Y direction, and the remaining adjustment slots 220 include a first straight slot segment 222a, a second straight slot segment 222b and a third straight slot segment 222c along their first extension direction, wherein the first straight slot segment 222a and the third straight slot segment 222c both extend along the Y direction, and the second straight slot segment 222b extends away from the center slot 221 along the first extension direction. Multiple first straight slot segments 222a and the center slot 221 all extend along the Y direction and are arranged at equal intervals along the X direction, and multiple third straight slot segments and the center slot 221 all extend along the Y direction and are arranged at equal intervals along the X direction, and the spacing between two adjacent first straight slot segments 222a is smaller than the spacing between two adjacent second straight slot segments 222b; when processing the adjustment slot 220, the center slot 221 can be first processed to obtain the center slot 221, and then the first straight slot segments 222a and the third straight slot segments 222c are processed at equal intervals on both sides of the center slot 221 in the X direction, and then the corresponding first straight slot segments 222a and the third straight slot segments 222c are connected to obtain the second straight slot segments 222b, so that the second straight slot segments 222b and the center slot 221 are arranged radially, and the angles between the two adjacent second straight slot segments 222b and between the center slot 221 and the adjacent second straight slot segments 222b are equal.

[0044] The arrangement of this type of adjustment groove 220 makes it necessary to only position the first straight groove segment 222a and the third straight groove segment 222c in the X-direction and Y-direction straight-line distances when processing the adjustment groove 220, without measuring and setting the inclination angle of the second straight groove segment relative to the Y-direction, thereby improving the processing convenience and accuracy of the adjustment groove 220.

[0045] Optionally, in this embodiment, if Figure 1 and Figure 2As shown, the base 100 includes a first substrate 110 and a second substrate 120 arranged at an angle, the adjustment plate 200 is slidably connected to a side surface of the first substrate 110 facing the second substrate 120, and the adjustment plate 200 is parallel to the first substrate 110, and a receiving space 600 is enclosed between the adjustment plate 200 and the second substrate 120; the adjustment seat 300 is accommodated in the receiving space 600 and is slidably connected to the second substrate 120, and the end of the adjustment seat 300 facing away from the adjustment plate 200 serves as a connecting end. On the one hand, the adjustment plate 200 and the adjustment seat 300 are located in the protective space surrounded by the first substrate 110 and the second substrate 120. The first substrate 110 and the second substrate 120 can isolate and protect the adjustment plate 200 and the adjustment seat 300, and the protection space is open on the side opposite to the first base 100 and the second base 100. The adjustment seat 300 and the adjustment plate 200 are exposed through the opening. When disassembling, the adjustment seat 300 and the adjustment plate 200 are not blocked or interfered, and the convenience of disassembly and assembly and the convenience of subsequent maintenance are both high. On the other hand, the first substrate 110 Extending in the XY plane, the adjustment plate 200 is always parallel to the first substrate 110 during the sliding process, and the adjustment seat 300 is located on the side of the adjustment plate 200 away from the first substrate 110, and the end of the adjustment seat 300 away from the adjustment plate 200 is used as a connecting end for connecting the clamping jaw 700 and other components that need to adjust the spacing. Then, the adjustment plate 200 does not block the adjustment seat 300, and the sliding stroke does not interfere with the connecting end and the components connected thereto, thereby improving the practicality of the equal-variable-distance adjustment component and reducing the restrictions on the size, shape, etc. of the clamping jaw 700 and other components.

[0046] Specifically, in this embodiment, Figure 1-Figure 3 As shown, the base 100 is provided with first guide rails 111 extending along the Y direction at both sides of the X direction, and the adjustment plate 200 is provided with first sliders 230 at both sides of the X direction, and the two first sliders 230 are slidably engaged with the two first guide rails 111 in a one-to-one correspondence. This is one of the specific forms in which the adjustment plate 200 is slidably connected to the base 100. When in use, when the driving component 400 drives the adjustment plate 200 to move, the first guide rails 111 can play a guiding and limiting role for the first sliders 230, thereby playing a guiding and limiting role for both ends of the adjustment plate 200 in the X direction, improving the position accuracy of the Y direction movement of the adjustment plate 200; at the same time, the first slider 230 is slidably engaged with the first guide rails 111, and the first guide rails 111 can also limit the X and Z direction movements of the first slider 230, thereby improving the stability of the adjustment plate 200 slidingly connected to the base 100.

[0047] Similarly, the plurality of adjustment seats 300 may also be slidably connected to the base 100 via guide rails or sliders. Specifically, Figure 1-Figure 3As shown, the base 100 is provided with a second guide rail 121 extending along the X direction, and the adjustment seat 300 is provided with a second slider 320, and the second slider 320 is slidably engaged with the second guide rail 121. When in use, the second guide rail 121 can play a guiding and limiting role in the X direction for the second slider 320, thereby ensuring the position adjustment of the adjustment seat 300, and the second slider 320 is slidably engaged with the second guide rail 121, and the second guide rail 121 can also limit the Y and Z direction movements of the second slider 320, thereby improving the stability of the adjustment seat 300 slidingly connected to the base 100.

[0048] In this embodiment, Figure 1 and Figure 2 As shown, the adjustment plate 200 is provided with a limiter 240, and the base 100 is provided with a limiter buffer 112 at both ends of the Y direction, and the limiter 240 corresponds to the limiter buffer 112. The limiter buffers 112 at both ends of the Y direction are used to elastically abut against the limiter 240, so as to limit the sliding stroke of the limiter 240 along the Y direction and play a role of vibration reduction and buffering when abutting and limiting. Accordingly, the sliding stroke of the plug-in protrusion 310 in the adjustment groove 220 can be limited, and the occurrence of rigid collision between the plug-in protrusion 310 and the two ends of the adjustment groove 220 can be reduced, so as to ensure the normal operation of the adjustment mechanism. Specifically, two limiter buffers 112 can be provided at both ends of the base 100 in the X direction, and correspondingly, a limiter 240 can be provided at both ends of the adjustment plate 200 in the X direction, so as to achieve double limiting at both ends of the X direction, thereby improving the limiting stability and accuracy.
