[0021] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0022] Please refer to FIG. 1. Figures 1-2 The first aspect of the present application provides a lamp strip clamp 1 which can adsorb lamp strips 80 of different lengths and has strong applicability.

[0023] The lamp strip clamp 1 comprises a suction assembly 10 and a lifting assembly 20. The suction assembly 10 comprises at least one first suction group 11, the first suction group 11 comprising a first suction unit 111 and a second suction unit 112, the first suction unit 111 and the second suction unit 112 being arranged along a first direction XX'.

[0024] The specific structure of the lamp strip clamp 1 will be introduced below. Figures 1-5 The specific structure of the lamp strip clamp 1 will be introduced below.

[0025] As shown in Figures 1-3 The lamp strip clamp 1 comprises a suction assembly 10 and a lifting assembly 20.

[0026] The suction assembly 10 is used for sucking the lamp strip 80 as a gripper of the lamp strip clamp 1, and the suction assembly 10 comprises at least one first suction group 11, that is, the number of the first suction group 11 can be one, two, three, four, five, six or more, and the specific number of the first suction group 11 is not limited here, and the designer can reasonably design according to the actual needs.

[0027] The first suction group 11 comprises the first suction unit 111 and the second suction unit 112.

[0028] The first suction unit 111 is used for sucking the lamp strip 80 as a structural member in the first suction group 11, and the specific structure of the first suction unit 111 will be introduced below.

[0029] The second suction unit 112 is used for sucking the lamp strip 80 as another structural member in the first suction group 11, and the specific structure of the second suction unit 112 will be introduced below.

[0030] The first suction unit 111 and the second suction unit 112 are arranged along the first direction XX'.

[0031] It can be understood that for each first adsorption group 11, the number of first adsorption units 111 can be one or multiple, and similarly, the number of second adsorption units 112 can be one or multiple.

[0032] When the number of first adsorption units 111 is one and the number of second adsorption units 112 is one, the one first adsorption unit 111 is arranged on one side of the one second adsorption unit 112 along the first direction XX'.

[0033] When the number of first adsorption units 111 is one and the number of second adsorption units 112 is multiple, the one first adsorption unit 111 is arranged on the same side of all second adsorption units 112 along the first direction XX'.

[0034] When the number of first adsorption units 111 is multiple and the number of second adsorption units 112 is one, all first adsorption units 111 can be arranged on the same side of the one second adsorption unit 112 along the first direction XX', or at least two first adsorption units 111 can be arranged on both sides of the one second adsorption unit 112 along the first direction XX'.

[0035] When the number of first adsorption units 111 is multiple and the number of second adsorption units 112 is multiple, all first adsorption units 111 can be arranged on the same side of all second adsorption units 112 along the first direction XX', or part of first adsorption units 111 can be arranged on the first side of all second adsorption units 112 along the first direction XX', and the remaining part of first adsorption units 111 can be arranged on the second side of all second adsorption units 112 along the first direction XX', which is opposite to the first side.

[0036] It should be noted that when the number of first adsorption groups 11 is multiple, the number of first adsorption units 111 in different first adsorption groups 11 can be equal or not equal, and similarly, the number of second adsorption units 112 in different first adsorption groups 11 can be equal or not equal.

[0037] The lifting assembly 20 serves as the power source of the lamp strip clamp 1, and the specific structure of the lifting assembly 20 will be introduced below.

[0038] The lifting assembly 20 is connected with the first adsorption unit 111.

[0039] The first adsorption group 11 has a first state and a second state, and the first adsorption group 11 can be switched between the first state and the second state. Among them, as Figure 4As shown, in the first state, the lifting assembly 20 is configured to drive the first adsorption unit 111 to move along the second direction ZZ' to align with the second adsorption unit 112, so that the first adsorption group 11 is used to adsorb the lamp strip 80 with a first preset length along the first direction XX'. Figure 5 As shown, in the second state, the lifting assembly 20 is configured to drive the first adsorption unit 111 to move along the second direction ZZ' to misalign with the second adsorption unit 112, so that the first adsorption group 11 is used to adsorb the lamp strip 80 with a second preset length along the first direction XX'. The first preset length is greater than the second preset length, and the first direction XX' intersects with the second direction ZZ'.

[0040] It should be noted that for each first adsorption group 11, when the first adsorption group 11 includes a plurality of first adsorption units 111, only when the lifting assembly 20 drives all the first adsorption units 111 to move along the second direction ZZ' to align with the second adsorption unit 112, it can be considered that the first adsorption group 11 is in the above-mentioned first state. For each first adsorption group 11, when the first adsorption group 11 includes a plurality of first adsorption units 111, as long as the lifting assembly 20 drives at least one first adsorption unit 111 to move along the second direction ZZ' to misalign with the second adsorption unit 112, it can be considered that the first adsorption group 11 is in the above-mentioned second state; and it can be understood that the lifting assembly 20 drives different numbers of first adsorption units 111 to move along the second direction ZZ' to misalign with the second adsorption unit 112 will make the first adsorption group 11 be in different second states, and the lengths of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX' are also different in different second states (that is, the specific values of the second preset length in different second states are different).

[0041] It should be noted that for the same first adsorption group 11, when the first adsorption group 11 includes a plurality of first adsorption units 111, the lengths of the lamp strip 80 adsorbed by the plurality of first adsorption units 111 along the first direction XX' can be equal or not equal. For different first adsorption groups 11, the lengths of the lamp strip 80 adsorbed by the first adsorption units 111 in different first adsorption groups 11 along the first direction XX' can be equal or not equal.

[0042] As shown, Figure 4 and Figure 5As shown, each second adsorption unit 112 of the first adsorption group 11 defines a straight line segment along the first direction XX', and each first adsorption unit 111 of the first adsorption group 11 defines an extension segment along the first direction XX', with the extension segment located on the extension line of the straight line segment. For a single first adsorption group 11, which includes only one second adsorption unit 112, the length of the straight line segment defined by all the first adsorption units 111 of the first adsorption group 11 is a first dimension D1 (that is, the length of the lamp strip 80 adsorbed by all the first adsorption units 111 of the first adsorption group 11 along the first direction XX' is the first dimension D1), and the length of the extension segment defined by the second adsorption unit 112 of the first adsorption group 11 is a second dimension D2 (that is, the length of the lamp strip 80 adsorbed by the second adsorption unit 112 of the first adsorption group 11 along the first direction XX' is the second dimension D2). This is used as an example for illustration. The first dimension D1 and the second dimension D2 can be equal or unequal. For example, in an embodiment of this application, the first dimension D1 is not equal to the second dimension D2, and the first dimension D1 is smaller than the second dimension D2.

[0043] Let D be the total length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX'. 总 Then D_total, D1, and D2 satisfy the following relation: D 总 =n*D1+D2, where n is the number of first adsorption units 111 contained in the first adsorption group 11, and n≥1, where n is a positive integer.

[0044] For example, when the first adsorption group 11 includes a first adsorption unit 111 (i.e., n=1), if the first adsorption group 11 is in the first state described above, then the total length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX' is the first preset size described above, and D 总 =D1+D2; If the first adsorption group 11 is in the second state described above, then the total length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX' is the second preset size described above, and D 总 =D2.

[0045] For example, when the first adsorption group 11 includes two first adsorption units 111 (i.e., n=2), if the first adsorption group 11 is in the first state described above, then the total length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX' is the first preset size described above, and D 总 =2*D1+D2; If the first adsorption group 11 is in the second state described above, then the total length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX' is the second preset size described above, and D 总 =D2, or, D 总 =D1+D2.

[0046] For example, when the first adsorption group 11 includes three first adsorption units 111 (i.e. n = 3), if the first adsorption group 11 is in the first state, the total length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX' is the first preset size, and D 总 = 3 * D1 + D2; if the first adsorption group 11 is in the second state, the total length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX' is the second preset size, and D 总 = D2, or D 总 = D1 + D2, or D 总 = 2 * D1 + D2.

[0047] Of course, the value of n can also be but is not limited to 4, 5, 6, 7, 8, etc., and D 总 By analogy, details are not repeated here.

[0048] Of course, the adsorption assembly 10 can also include a second adsorption group (not shown in the figure), the number of the second adsorption group can be one or multiple, and the second adsorption group can only include the second adsorption unit 112. It should be noted that when the adsorption assembly 10 includes the first adsorption group 11 and the second adsorption group, the arrangement of the first adsorption group 11 and the second adsorption group is not limited here, and the first adsorption group 11 and the second adsorption group can be arranged arbitrarily along the third direction YY' (described below).

[0049] Based on the lamp strip adsorption structure in the embodiment of the present application, the lifting assembly 20 can drive the first adsorption unit 111 to move along the second direction ZZ' to align with the second adsorption unit 112 to make the first adsorption group 11 in the first state, at which time the first adsorption group 11 can adsorb the lamp strip 80 with a length of the first preset size along the first direction XX'; the lifting assembly 20 can also drive the first adsorption unit 111 to move along the second direction ZZ' to misalign with the second adsorption unit 112 to make the first adsorption group 11 in the second state, at which time the first adsorption group 11 can adsorb the lamp strip 80 with a length of the second preset size along the first direction XX'; the lamp strip clamp 1 realizes adsorption of lamp strips 80 of different lengths, and enhances the applicability of the lamp strip clamp 1.

[0050] Further, considering that the number of the first adsorption group 11 in the adsorption assembly 10 can be one or multiple, and the specific implementation of the lifting assembly 20 driving the first adsorption unit 111 to move along the second direction ZZ' can be many, and can but is not limited to include the following several embodiments.

[0051] For example, Figure 1 and Figure 3As shown, in the first embodiment, the lifting assembly 20 comprises at least one first lifting group 21 equal in number to the first adsorption groups 11, each first lifting group 21 being connected with the first adsorption units 111 in one first adsorption group 11 to drive the first adsorption units 111 in the corresponding first adsorption group 11 to move along the second direction ZZ’.

[0052] It should be noted that when the first adsorption group 11 comprises a plurality of first adsorption units 111, the first lifting group 21 can drive all the first adsorption units 111 in the corresponding first adsorption group 11 to move along the second direction ZZ’ simultaneously, or the first lifting group 21 can drive all the first adsorption units 111 in the corresponding first adsorption group 11 to move along the second direction ZZ’ at different times.

[0053] In the second embodiment, the lifting assembly 20 comprises at least one first lifting group 21 unequal in number to the first adsorption groups 11, each first lifting group 21 being connected with the first adsorption units 111 in at least one first adsorption group 11 to drive the first adsorption units 111 in the corresponding first adsorption group 11 to move along the second direction ZZ’. At this time, it can be that one first lifting group 21 is connected with the first adsorption units 111 in multiple first adsorption groups 11 to drive the first adsorption units 111 in the multiple first adsorption groups 11 connected therewith to move along the second direction ZZ’, or it can be that multiple first lifting groups 21 are connected with the first adsorption units 111 in one first adsorption group 11 to drive the first adsorption units 111 in the one first adsorption group 11 connected therewith to move along the second direction ZZ’.

[0054] Further, considering that the number of the first adsorption units 111 in the first adsorption group 11 can be one or multiple, and that the specific implementation mode of the first lifting group 21 driving the first adsorption units 111 in the corresponding first adsorption group 11 to move along the second direction ZZ’ can be many, and can but not limited to include the following several embodiments.

[0055] For example, as shown in FIG. 1, the first lifting group 21 can be connected with the first adsorption units 111 in one first adsorption group 11 to drive the first adsorption units 111 in the one first adsorption group 11 to move along the second direction ZZ’. Figure 1 For example, as shown in FIG. 1, the first lifting group 21 can be connected with the first adsorption units 111 in one first adsorption group 11 to drive the first adsorption units 111 in the one first adsorption group 11 to move along the second direction ZZ’. Figure 3As shown, in the first embodiment, at least one first lifting group 21 comprises first lifting units 211 equal in number to the first adsorption units 111 of the corresponding first adsorption group 11, and each first lifting unit 211 is connected with one first adsorption unit 111 to drive the corresponding first adsorption unit 111 to move along the second direction ZZ'.

[0056] It should be noted that all the first lifting units 211 can drive the corresponding first adsorption units 111 to move along the second direction ZZ' simultaneously, or all the first lifting units 211 can drive the corresponding first adsorption units 111 to move along the second direction ZZ' at different times.

[0057] In the second embodiment, at least one first lifting group 21 comprises first lifting units 211 unequal in number to the first adsorption units 111 of the corresponding first adsorption group 11, and each first lifting unit 211 is connected with at least one first adsorption unit 111 to drive the corresponding first adsorption unit 111 to move along the second direction ZZ'. At this time, it can be that one first lifting unit 211 is connected with multiple first adsorption units 111 in the same first adsorption group 11 to drive the multiple first adsorption units 111 in the same first adsorption group 11 to move along the second direction ZZ', or it can be that multiple first lifting units 211 are connected with one first adsorption unit 111 in the same first adsorption group 11 to drive the one first adsorption unit 111 in the same first adsorption group 11 to move along the second direction ZZ'.

[0058] Further, as shown in FIG. 1, in the first embodiment, the first adsorption group 11 comprises first adsorption units 111 equal in number to the first lifting units 211 of the corresponding first lifting group 21, and each first adsorption unit 111 is connected with one first lifting unit 211 to be driven by the corresponding first lifting unit 211 to move along the second direction ZZ'. Figure 3As shown, in some embodiments, the first lifting unit 211 comprises a first power element 2111 and a first carrier 2112; the number of the first power element 2111 can be one or multiple; the first carrier 2112 is connected with the power output end of the first power element 2111, and the first carrier 2112 is connected with the corresponding first adsorption unit 111; the first power element 2111 is configured to drive the first carrier 2112 to move along the second direction ZZ', so as to drive the corresponding first adsorption unit 111 to move along the second direction ZZ'. Wherein, the first carrier 2112 is used to provide support for the first adsorption unit 111, and the specific form of the first carrier 2112 is various, which is not limited here, for example, the first carrier 2112 can be a flat plate structure, a grid structure or a screen structure. The specific connection mode between the first carrier 2112 and the movable end of the first power element 2111 is various, which is not limited here, for example, the first carrier 2112 and the movable end of the first power element 2111 can be fixedly connected or movably connected. In this design, the first power element 2111 drives the first carrier 2112 connected therewith to move along the second direction ZZ', so that the first adsorption unit 111 connected with the first carrier 2112 also moves along the second direction ZZ', and the first adsorption unit 111 moves along the second direction ZZ' to realize the alignment and staggering between the first adsorption unit 111 and the second adsorption unit 112, so as to switch the first adsorption group 11 between the first state and the second state, so as to adapt to the lamp strip 80 of different lengths adsorbed along the first direction XX', and effectively enhance the applicability of the lamp strip clamp 1.

[0059] Specifically, the first power element 2111 can be a cylinder, and the first carrier 2112 is a carrier plate, the piston rod of the cylinder is fixedly connected with the carrier plate as the power output end, and the carrier plate is connected with the first adsorption unit 111. When the piston rod of the cylinder extends along the second direction ZZ', the carrier plate moves along the second direction ZZ' under the action of the cylinder to align the first adsorption unit 111 with the second adsorption unit 112, so that the first adsorption group 11 is in the above-mentioned first state; when the piston rod of the cylinder shortens along the second direction ZZ', the carrier plate moves along the second direction ZZ' under the action of the cylinder to stagger the first adsorption unit 111 with the second adsorption unit 112, so that the first adsorption group 11 is in the above-mentioned second state.

[0060] Specifically, the first power element 2111 can also include a motor 411 (not the same motor 411 as the motor 411 of the transmission set 41 introduced below) and a lead screw, the first carrier 2112 is a carrier plate, the rotating shaft of the motor 411 is fixedly connected with the lead screw, the lead screw serves as a power output end and is movably connected with the carrier plate, and the carrier plate is connected with the first adsorption unit 111. The motor 411 drives the lead screw to rotate to drive the carrier plate to move along the second direction ZZ' relative to the lead screw, and the movement of the carrier plate drives the first adsorption unit 111 connected therewith to move along the second direction ZZ' to be aligned or staggered with the second adsorption unit 112, so as to switch the first adsorption set 11 between the first state and the second state.

[0061] Further, as shown in some embodiments, Figure 3 the first adsorption unit 111 includes a second carrier 1111 and a first suction disc 1112; the second carrier 1111 is connected with the lifting assembly 20 (specifically, the first carrier 2112 of the first lifting unit 211), and the inside of the second carrier 1111 has an air channel; the number of the first suction disc 1112 is at least one, the first suction disc 1112 is connected with the second carrier 1111 and communicates with the air channel. Among them, the second carrier 1111 is used to provide support for the first suction disc 1112, and the second carrier 1111 is used to provide an air channel for air flow circulation. The specific form of the second carrier 1111 is various, which is not limited here, for example, the second carrier 1111 can be a long strip-shaped carrier plate. The first suction disc 1112 is fixedly connected with the second carrier 1111, and the specific connection mode between the first suction disc 1112 and the second carrier 1111 is various, which is not limited here, for example, the first suction disc 1112 can be connected with the second carrier 1111 by screwing. In this design, by providing at least one first suction disc 1112 on each second carrier 1111, when the first adsorption set 11 is in the first state, at least one first suction disc 1112 cooperates with the second suction disc 1122 (introduced below) of the second adsorption unit 112 to adsorb the same light bar 80, thereby improving the stability and safety of the light bar 80 taking and placing process.

[0062] Further, as shown in some embodiments, Figure 1 and Figure 3As shown, in some embodiments, the lifting assembly 20 further comprises at least one second lifting group 22 equal in number to the first adsorption groups 11, each second lifting group 22 is connected with the second adsorption units 112 in one first adsorption group 11 to drive the second adsorption units 112 in the corresponding first adsorption group 11 to move along the second direction ZZ'. The lamp strip clamp 1 further comprises a base 30 and a transmission assembly 40; the transmission assembly 40 is connected with the base 30, the first lifting group 21 and the second lifting group 22, and the transmission assembly 40 is configured to drive the first lifting group 21 and the second lifting group 22 corresponding to the same first adsorption group 11 to move along the third direction YY' simultaneously; the first direction XX', the second direction ZZ' and the third direction YY' are perpendicular to each other. In this design, for the same first adsorption group 11, the first lifting group 21 is connected with the first adsorption units 111, and the second lifting group 22 is connected with the second adsorption units 112; by designing the transmission assembly 40, the transmission assembly 40 drives the first lifting group 21 and the second lifting group 22 corresponding to the same first adsorption group 11 to move along the third direction YY' simultaneously, so that the first adsorption units 111 connected with the first lifting group 21 and the second adsorption units 112 connected with the second lifting group 22 can also move along the third direction YY' simultaneously, thereby changing the position of the first adsorption group 11 along the third direction YY'.

[0063] It should be noted that the main purpose of the second lifting group 22 driving the second adsorption units 112 to move along the second direction ZZ' is not to change the length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX', but to avoid interference between the second adsorption group and other components during the movement of the lamp strip clamp 1, or to reduce the overall space occupancy rate of the lamp strip clamp 1 when it is idle. It is worth mentioning that when the first adsorption group 11 includes multiple second adsorption units 112, the second lifting group 22 driving the second adsorption units 112 to move along the second direction ZZ' can also achieve the secondary purpose of changing the length of the lamp strip 80 adsorbed by the first adsorption group 11 along the first direction XX'.

[0064] Here, the specific connection between the second lifting group 22 and the second adsorption unit 112 is not limited, for example, the number of second lifting groups 22 is equal to the number of first adsorption groups 11, and each second lifting group 22 is connected with the second adsorption units 112 in one first adsorption group 11 to drive the second adsorption units 112 in the corresponding first adsorption group 11 to move along the second direction ZZ'. At least one second lifting group 22 comprises second lifting units 221 equal in number to the second adsorption units 112 of the corresponding first adsorption group 11, and each second lifting unit 221 is connected with one second adsorption unit 112 to drive the corresponding second adsorption unit 112 to move along the second direction ZZ'.

[0065] Of course, the specific form of the second lifting unit 221 is not limited here, for example, the second lifting unit 221 includes a second power element 2211 and a fourth bearing 2212, the number of the second power element 2211 can be one or more, the fourth bearing 2212 is connected with the power output end of the second power element 2211, the fourth bearing 2212 is connected with the corresponding second adsorption unit 112, and the second power element 2211 is configured to drive the fourth bearing 2212 to move along the second direction ZZ', so as to drive the corresponding second adsorption unit 112 to move along the second direction ZZ'. Specifically, the second power element 2211 can be a cylinder, and the fourth bearing 2212 is a bearing plate. The piston rod of the cylinder is fixedly connected with the bearing plate as the power output end, and the bearing plate is connected with the second adsorption unit 112. The piston rod of the cylinder makes telescopic movement along the second direction ZZ' to drive the bearing plate to move along the second direction ZZ', and the movement of the bearing plate drives the second adsorption unit 112 connected therewith to move along the second direction ZZ'.

[0066] Of course, the specific form of the second adsorption unit 112 is not limited here, and the specific form of the second adsorption unit 112 can be the same as or different from that of the first adsorption unit 111. For example, when the specific form of the second adsorption unit 112 is the same as that of the first adsorption unit 111, specifically, the second adsorption unit 112 includes a fifth bearing 1121 and a second suction cup 1122, the fifth bearing 1121 is connected with the fourth bearing 2212 of the second lifting unit 221, the fifth bearing 1121 has an air channel in the inside, the number of the second suction cup 1122 is at least two, and the second suction cup 1122 is connected with the fifth bearing 1121 and communicates with the air channel. It should be noted that when the first adsorption group 11 is in the above-mentioned second state, only the second suction cup 1122 of the second adsorption unit 112 is used to adsorb the lamp strip at this time, and at least two second suction cups 1122 are used to adsorb the same lamp strip 80, which improves the stability and safety of the lamp strip 80 taking and placing process.

In this design, when the adsorption assembly 10 includes multiple first adsorption groups 11, each transmission group 41 can drive a first adsorption group 11 connected therebetween to move along the third direction YY’, so that the interval between any two adjacent first adsorption groups 11 along the third direction YY’ can be changed, thereby changing the interval between any two adjacent first adsorption groups 11 along the third direction YY’ to adapt to the adsorption of the lamp strip 80 with different intervals, and enhance the applicability of the lamp strip clamp 1.

[0068] It should be noted that for each first adsorption group 11, the transmission group 41 simultaneously drives the first lifting group 21 and the second lifting group 22 corresponding to the same first adsorption group 11 to move along the third direction YY’ at the same time, so that the corresponding first adsorption group 11 moves along the third direction YY’; for different first adsorption groups 11, the transmission groups 41 can simultaneously / not simultaneously drive the first lifting group 21 and the second lifting group 22 corresponding to the different first adsorption groups 11 to move along the third direction YY’ at the same time, so that all the first adsorption groups 11 can move along the third direction YY’ at the same time / not at the same time.

The sliding connection between the third carrier 413 and the base plate 31 is various, which is not limited here, for example, the sliding connection between the third carrier 413 and the base plate 31 can be realized by sliding rails and sliding grooves. In this design, the motor 411 works to drive the gear 412 connected with the rotating shaft to move along the third direction YY’ relative to the rack 32, the movement of the gear 412 drives the motor 411 to move along the third direction YY’ together with the gear 412, the movement of the motor 411 drives the third carrier 413 to move along the third direction YY’ relative to the base plate 31, the movement of the third carrier 413 drives the corresponding first lifting set 21 and the second lifting set 22 to move along the third direction YY’, and the movement of the first lifting set 21 and the second lifting set 22 drives the corresponding same first adsorption set 11 to move along the third direction YY’, so as to change the position of the first adsorption set 11 along the third direction YY’, so that the light bar clamp 1 adsorbs light bars 80 with different intervals, and the applicability of the light bar clamp 1 is enhanced.
