[0001] The present invention relates to the technical field of electronic equipment production, and in particular to a carrier. Background Art

[0002] In the processing and production of variable-frequency home appliances, elevators and other electronic equipment, frequency converters generally adopt intelligent power module drive solutions. In the current intelligent power module packaging process, the intelligent power module usually needs to be locked to the heat sink through fasteners. Therefore, the heat sink needs to be clamped and positioned in advance.

[0003] When clamping workpieces, most of the clamping devices mounted on existing carriers can only achieve the linkage of the clamping parts in one direction. To achieve the linkage of the clamping parts in multiple directions, different driving mechanisms need to be set up. Different driving mechanisms drive the clamping parts in multiple directions at the same time, thereby enabling the clamping parts in multiple directions to be linked. The linkage method is cumbersome and the structure is complex.

[0004] Therefore, a vehicle is urgently needed to solve the above problems. Summary of the invention

[0015] Preferably, a pair of the synchronizing members are respectively connected to two sides of a pair of the first clamping members along the second direction.

[0016] Preferably, a pair of the synchronizing members are connected to two sides of any one of the first clamping members along the second direction.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] This embodiment provides a carrier, which can be applied to automated processing equipment to clamp various types of workpieces such as plates and boxes, so as to facilitate reprocessing of the workpieces or assembly of other workpieces on the workpieces. When the carrier is working, the linkage of the clamps in different directions can be achieved without different driving mechanisms driving the clamps in different directions at the same time.

[0048] Combination Figures 1 to 7 In this embodiment, a heat sink and an intelligent power module connected to the heat sink are taken as an example, that is, the first workpiece is the heat sink, and the second workpiece is the intelligent power module. The carrier is specifically described as follows:

[0049] First see Figure 1 and Figure 6The carrier includes a carrier 1, a pair of first clamping members 2, a pair of second clamping members 3 and a pair of synchronization members 4. The carrier 1 is configured to carry a first workpiece. The pair of first clamping members 2 are movably arranged on both sides of the carrier 1 along the first direction, and can move toward or away from each other to cooperate in clamping or releasing the first workpiece along both sides of the first direction. The pair of second clamping members 3 are movably arranged on both sides of the carrier 1 along a second direction perpendicular to the first direction, and the side of the pair of second clamping members 3 facing away from the carrier 1 is respectively provided with a first magnetic member 31. The pair of synchronization members 4 are respectively located on the outer side of the pair of second clamping members 3 facing away from the carrier 1. The pair of synchronization members 4 are configured to repel the pair of first magnetic members 31 when the pair of first clamping members 2 cooperate to clamp the first workpiece, so that the pair of second clamping members 3 cooperate to clamp the first workpiece along both sides of the second direction, and adsorb the pair of first magnetic members 31 when the pair of first clamping members 2 release the first workpiece, so that the pair of second clamping members 3 release the first workpiece.

[0050] Since the pair of second clamping members 3 are movably arranged on both sides of the platform 1 along the second direction perpendicular to the first direction, that is, the pair of second clamping members 3 can move toward or away from each other, and the first magnetic member 31 is respectively arranged on the side of the pair of second clamping members 3 facing away from the platform 1, and the outer side of the pair of second clamping members 3 facing away from the platform 1 is provided with a pair of magnetic synchronous members 4, when the pair of first clamping members 2 is in a working state of clamping the first workpiece, the magnetism of the pair of synchronous members 4 is the same as the magnetism of the first magnetic member 31 on the pair of second clamping members 3, and the pair of synchronous members 4 can respectively apply a repulsive force to the pair of second clamping members 3 , so that the second clamping members 3 move toward each other, and then cooperate to clamp the first workpiece on both sides along the second direction; when the pair of first clamping members 2 are in the working state of releasing the first workpiece, the magnetism of the pair of synchronous members 4 is opposite to the magnetism of the first magnetic members 31 on the pair of second clamping members 3, and the pair of synchronous members 4 can respectively apply attractive force to the pair of second clamping members 3, so that the second clamping members 3 move back to back, and then release the first workpiece, thereby realizing the first clamping member 2 and the second clamping member 3 to clamp or release the first workpiece in the first direction and the second direction. The linkage method of the carrier in this embodiment is simple and the structure is simple.

[0051] At the same time, in order to enable a pair of first clamping members 2 to move toward or away from each other, as Figure 2As shown, in the present embodiment, the carrier also includes a driving device 5, the driving device 5 includes a first moving member 51, a second moving member 52 and a driving mechanism (not shown in the figure), a first rack 511 is arranged on the first moving member 51, the first moving member 51 and the second moving member 52 are respectively connected to a pair of first clamping members 2, a second rack 521 is arranged on the second moving member 52, the teeth of the second rack 521 and the first rack 511 are relatively parallelly arranged, and a gear 53 is arranged therebetween, the second rack 521 and the first rack 511 are both meshed with the gear 53, and the driving mechanism can drive the first moving member 51 or the second moving member 52 to make the first moving member 51 and the second moving member 52 move in opposite directions.

[0052] That is, the driving mechanism first drives the first moving member 51 to move in the first direction, and through the transmission between the first rack 511, the gear 53 and the second rack 521, the second moving member 52 and the first moving member 51 move in opposite directions, thereby driving a pair of first clamping members 2 to move toward each other to clamp the first workpiece on both sides along the first direction, and at the same time, a pair of second clamping members 3 clamp the first workpiece on both sides along the second direction. After completing subsequent processing, the driving mechanism will drive the second moving member 52 to move in the first direction, and through the transmission between the second rack 521, the gear 53 and the first rack 511, the first moving member 51 and the second moving member 52 move in opposite directions, thereby driving a pair of first clamping members 2 to move back to back to release the first workpiece, and at the same time, a pair of second clamping members 3 release the first workpiece.

[0053] In this embodiment, two driving mechanisms are provided, and the two driving mechanisms can respectively drive the first moving member 51 and the second moving member 52, wherein the driving mechanism provided at the first moving member 51 first drives the first moving member 51 to move along the first direction, and after completing subsequent processing, the driving mechanism provided at the second moving member 52 drives the second moving member 52 to move along the first direction.

[0054] It is understandable that in other optional embodiments, the driving mechanism may be provided as only one, the driving mechanism first drives the first moving member 51 , and after completing subsequent processing, the driving mechanism moves to the second moving member 52 to drive the second moving member 52 .

[0055] In order to limit the moving distance of the first movable member 51 and the second movable member 52 to prevent damage to the first workpiece, the first movable member 51 and the second movable member 52 are respectively connected to a pair of first clamping members 2 through two connecting plates 6, and two limiting holes 7 are provided on the carrier. The two connecting plates 6 are respectively inserted into the two limiting holes 7 and can move in the two limiting holes 7 respectively.

[0056] At the same time, it should be noted that when a pair of first clamping members 2 performs a clamping action, the displacement of the pair of first clamping members 2 is limited by the limit hole 7. If the size of the first workpiece has a positive deviation from the standard size, the pair of first clamping members 2 will be over-pressed against the first workpiece, causing damage to the pair of first clamping members 2 or the first workpiece. If the size of the first workpiece has a negative deviation from the standard size, it is difficult to ensure that the pair of first clamping members 2 can reliably clamp the first workpiece, affecting the processing quality and results. However, in this embodiment, a compression spring 61 is provided between the connecting plate 6 and the first clamping member 2, so that the carrier can allow a certain size deviation of the first workpiece and will not form a rigid pressure on the first workpiece.

[0057] Specifically, in order to enable a pair of first clamping members 2 and a pair of second clamping members 3 to be linked, a pair of synchronization members 4 each include a connecting portion 41 and a driving portion 42, the driving portion 42 is connected to the first clamping member 2 through the connecting portion 41 and extends toward the second clamping member 3 in a first direction, and a second magnetic member 421 having the same magnetic properties as the first magnetic member 31 and a third magnetic member 422 having opposite magnetic properties to the first magnetic member 31 are sequentially arranged on one side of the driving portion 42 close to the second clamping member 3, so that when a pair of first clamping members 2 cooperate to clamp the first workpiece, the second magnetic member 421 is opposite to the first magnetic member 31, and when a pair of first clamping members 2 release the first workpiece, the third magnetic member 422 is opposite to the first magnetic member 31.

[0058] In this embodiment, a pair of synchronous members 4 is connected to the first clamping member 2, that is, the pair of synchronous members 4 can move with the first clamping member 2, and its driving part 42 extends toward the second clamping member 3 in the first direction and is located on the outer side of the second clamping member 3 facing away from the carrier 1. When the carrier is not working, the third magnetic member 422 is opposite to the first magnetic member 31, and the pair of second clamping members 3 are adsorbed and fit with the pair of synchronous members 4. When the pair of first clamping members 2 move toward each other, the second magnetic member 421 located on the driving part 42 moves with the first clamping member 2. When the pair of first clamping members 2 move to a position where they can clamp the first workpiece on both sides along the first direction, When the first magnetic member 31 is in the initial position, the second magnetic member 421 is opposite to the first magnetic member 31, and the second magnetic member 421 exerts a repulsive force on the first magnetic member 31, and the pair of second clamping members 3 move toward each other to clamp the first workpiece on both sides along the second direction. When the pair of first clamping members 2 move in opposite directions, the third magnetic member 422 located on the driving part 42 moves with the first clamping member 2. When the pair of first clamping members 2 move to the initial position, the second magnetic member 421 is opposite to the first magnetic member 31, and the third magnetic member 422 exerts an attractive force on the first magnetic member 31, and the pair of second clamping members 3 move in opposite directions to release the first workpiece and return to the initial position.

[0059] Preferably, in this embodiment, the first magnetic part 31, the second magnetic part 421 and the third magnetic part 422 are all magnets, and the number of the first magnetic part 31, the second magnetic part 421 and the third magnetic part 422 is equal, and they are all set to be multiple, wherein the end of the first magnetic part 31 close to the synchronous part 4 is the S pole, and the end of the second magnetic part 421 opposite to the first magnetic part 31 is the S pole, and the end of the second magnetic part 421 opposite to the first magnetic part 31 is the N pole.

[0060] Of course, in other optional embodiments, the end of the first magnetic member 31 close to the synchronous member 4 is the N pole, and the end of the second magnetic member 421 opposite to the first magnetic member 31 is the N pole, and the end of the second magnetic member 421 opposite to the first magnetic member 31 is the S pole.

[0061] Correspondingly, a pair of synchronizers 4 are respectively connected to the two sides of a pair of first clamping members 2 along the second direction, that is, a pair of synchronizers 4 are respectively connected to the pair of first clamping members 2 and are located on the two sides of the pair of first clamping members 2 along the second direction, and the extension directions of the driving parts 42 of the pair of synchronizers 4 are opposite.

[0062] When the first clamping member 2 clamps the first workpiece on both sides along the first direction, the first clamping member 2 and the second clamping member 3 can form a receiving cavity on the surface of the first workpiece, and the receiving cavity can receive the second workpiece so that the positions to be connected on the second workpiece and the first workpiece are aligned.

[0063] In this embodiment, a pair of first clamping members 2 each include a first clamping block 21 and a second clamping block 22, the first clamping block 21 is located below the second clamping block 22, the second clamping block 22 extends outward from the first clamping block 21, the first clamping blocks 21 of the pair of first clamping members 2 clamp the first workpiece on both sides along the first direction, so that the second clamping blocks 22 of the pair of first clamping members 2 are located above the first workpiece, and the second clamping blocks 22 include extension portions 221, when the first clamping blocks 21 of the pair of first clamping members 2 clamp the first workpiece on both sides along the first direction, the extension portions 221 of the pair of first clamping members 2 abut against each other, the pair of second clamping members 3 include a third clamping block 32, and the end of the third clamping block 32 close to the first workpiece is set in a stepped shape, that is, the third clamping The block 32 is recessed inwardly at the lower end near the first workpiece to form a first clamping surface 321. The first clamping surfaces 321 of a pair of second clamping members 3 can clamp the first workpiece on both sides along the second direction. The end surface of the third clamping block 32 near one end of the first workpiece forms a second clamping surface 322. When the first clamping member 2 clamps the first workpiece on both sides along the first direction, the second clamping surfaces 322 of the pair of second clamping members 3 and the extension portions 221 of the pair of first clamping members 2 form an accommodating cavity on the surface of the first workpiece. Since connecting holes are provided on both the second workpiece and the first workpiece, when the second workpiece is placed in the accommodating cavity, the connecting holes of the two can be aligned, and then the first workpiece and the second workpiece are connected together by other external mechanisms such as a robot.

[0064] Embodiment 2

[0065] Compared with the first embodiment, the difference of this embodiment is that a pair of synchronizers 4 is connected to both sides of any first clamping member 2 along the second direction, that is, in this embodiment, a pair of synchronizers 4 is connected to both sides of the same first clamping member 2 along the second direction.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
