Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-4, a horizontal driving assembly 100 according to the present invention is provided. The horizontal driving assembly 100 provided by the utility model can be applied to various automatic processing equipment of flexible circuit boards, and is used for driving the translation of a processing jig for the flexible circuit boards. The horizontal driving assembly 100 provided by the utility model has the advantages of simple structure, convenience in installation and low space occupancy rate, and the maximum stroke range capable of being driven can be increased on the basis of the maximum driving stroke of the driving part, so that the horizontal driving assembly can be suitable for arrangement in various narrow spaces and is used for relative translation between two parts.

Further, as shown in fig. 1, it is a schematic view of a three-dimensional structure of the fixture of the flexible circuit board after the product positioning assembly is disposed thereon. The jig has an upper mold and a lower mold, which are oppositely disposed, the upper mold of the jig is the upper plate 80 in this embodiment, and the lower mold of the jig is the lower plate 90 in this embodiment. The horizontal driving assembly 100 of the present invention is used to drive the upper plate 80 and the lower plate 90 to move horizontally relative to each other.

Specifically, as shown in fig. 1 to 3, the horizontal driving assembly 100 of the present invention includes a first linear guide 10, a second linear guide 20, and a third linear guide 30 fixed to a top surface 91 of a lower plate 90, and a driving member 40 fixed to a bottom surface 92 of the lower plate 90 and disposed parallel to the third linear guide 30. All the components of the horizontal driving assembly 100 are fixed to the lower plate 90 located below, wherein the first linear guide 10, the second linear guide 20 and the third linear guide 30 are fixed to the top surface 91 of the lower plate 90, and only the driving member 40 is fixed to the bottom surface 92 of the lower plate 90, so that the distance between the upper plate 80 and the lower plate 90 can be greatly required. Also in this embodiment, the upper plate 80 needs to be relatively translated in a horizontal plane with respect to the lower plate 90, so there is no space above the lower plate 90 for placement of the driving member 40. Meanwhile, a product positioning assembly is required to be arranged at the center of the lower part of the lower plate 90 and at the top of the upper plate 80, and no space for placing the driving member 40 is available. Accordingly, as shown in fig. 1, the driving member 40 is disposed on a side of the bottom surface 92 of the lower plate 90, thereby preventing interference between the driving member 40 and the upper plate 80 and the product positioning assembly fixed to the lower plate 90.

Further, as shown in fig. 1 to 3, the first linear guide 10 is provided with a first slider 11 fixedly connected to the upper plate 80, the second linear guide 20 is provided with a second slider 21 fixedly connected to the upper plate 80, and the first linear guide 10 and the second linear guide 20 are arranged in parallel to each other. The first linear guide 10 and the second linear guide 20 are disposed parallel to each other, and also fix the relative position between the upper plate 80 and the lower plate 90 located above them. And, both the first and second linear guides 10 and 20 movably connect the upper plate 80 and the lower plate 90 through the linear guides so that the upper plate 80 can be horizontally moved in a direction in which the first or second linear guides 10 and 20 are disposed, thereby defining a moving direction of the upper plate 80 with respect to the lower plate 90.

Specifically, the third linear guide 30 disposed on the top surface 91 of the lower plate 90 is provided with a third slider 31 fixedly connected with the driving member 40, and a movably connected link 50 is disposed between the third slider 31 and the first slider 11. The first and second linear guides 10 and 20 provided on the top surface 91 of the lower plate 90 serve to define the relative position between the upper plate 80 and the lower plate 90. And the third linear guide 30 on the top surface 91 is used for realizing synchronous movement of the driving member 40 matched with the third linear guide, so that the driving member 40 below the lower plate 90 drives the third slide block 31 above the lower plate 90 to move relatively on the horizontal plane. The third sliding block 31 of the third linear guide 30 is movably connected with the first sliding block 11 of the first linear guide 10 through a connecting rod 50, so that the horizontal movement of the third sliding block 31 can change the relative position of the first sliding block 11 on the first linear guide 10. The first linear guide 10 and the third linear guide 30 provided by the present invention are arranged in a staggered manner, so that when the third slider 31 moves, the movement of the first slider 11 driven by the connecting rod 50 is influenced by the length and the relative position of the connecting rod 50, and thus the maximum movable stroke of the first slider 11 is greater than that of the third slider 31. In this embodiment, the maximum stroke of the third slider 31 on the third linear guide 30 is the maximum stroke range of the driving member 40, and the maximum stroke of the first slider 11 on the first linear guide 10 is the sum of the maximum distance of the link 50 and the maximum stroke of the third slider 31. Therefore, in the horizontal driving assembly 100 provided by the present invention, the maximum distance that the upper plate 80 can translate, i.e. the maximum distance that the first sliding block 11 on the first linear guide 10 can move, is greater than the maximum distance that the driving member 40 can drive.

Further, as shown in fig. 1, in the present embodiment, the third linear guide 30 is disposed perpendicular to the first linear guide 10, and the third linear guide 30 is located at one side of the first linear guide 10. The position at which the third linear guide 30 is disposed on the top surface 91 of the lower plate 90 is determined by the position at which the driving member 40 can be placed on the bottom surface 92 of the lower plate 90. In this embodiment, the driving member 40 is located on the side of the bottom surface 92 of the lower plate 90, and correspondingly, the third linear guide 30 is disposed on the top surface 91 of the lower plate 90 in parallel therewith. As shown in fig. 3, the length of the third linear guide 30 is smaller than the length of the first linear guide 10.

Further, as shown in fig. 1 and 2, in the horizontal driving assembly 100 of the present invention, the side surface of the first slider 11 on the first linear guide 10 is provided with the mounting block 12 extending toward the third linear guide 30. The mounting block 12 is integrally formed with the first slide block 11, and the mounting block 12 is located on a side surface of the first slide block 11 close to the third linear guide 30, and the mounting block 12 is used for realizing the movable connection between the first slide block 11 and the connecting rod 50. A first mounting hole (not shown) is formed in the mounting block 12 and movably connected to the connecting rod 50, and one end of the connecting rod 50 is fixed to the first mounting hole (not shown) through a first hinge assembly 51. The two ends of the connecting rod 50 are respectively provided with a mounting hole movably connected with the first slider 11 and the third slider 31, and the connecting rod 50 is located above the mounting block 12 of the first slider 11, and the first hinge assembly 51 is used for realizing the hinge connection between the connecting rod 50 and the first slider 11.

Specifically, as shown in fig. 4, the first hinge assembly 51, which is hinged to the end of the connecting rod 50 connected to the mounting block 12 of the first sliding block 11, includes a first locking member 511, which is inserted through the end of the connecting rod 50 and fixed in a first mounting hole (not shown), and a first bearing 512, which is disposed at the end of the connecting rod 50 and sleeved on the first locking member 511. The first locking member 511 is a coupling member such as a screw, a rivet, or the like, which can be inserted between the link 50 and the mounting block 12. And the first bearing 512 is disposed in the mounting hole of the link 50 such that the link 50 can horizontally rotate with respect to the axis of the first locking member 511.

Further, as shown in fig. 1 and 2, the present invention provides a horizontal driving assembly 100 in which at least one second mounting hole 32 connected to the link 50 is formed on the top surface of the third slider 31 on the third linear guide 30. In the present embodiment, as shown in fig. 4, four second mounting holes 32 are provided in the third slider 31. During actual assembly, the specific position of the movable connection between the connecting rod 50 and the third sliding block 31 can be adjusted according to actual needs. And one end of the connecting rod 50 is fixed to a second mounting hole 32 of the third slider 31 by a second hinge assembly 52.

The second locking member 521 and the second bearing 522 are identical to the first locking member 511 and the first bearing 512 of the first hinge assembly 51 in function and function, and will not be described in detail herein.

Further, in order to improve the accuracy of the horizontal translational position of the upper plate 80 relative to the lower plate 90, as shown in fig. 1 and 2, the side surface of the second linear guide 20 in the horizontal driving assembly 100 provided by the present invention is provided with at least one stopper 22 capable of abutting against the second slider 21, and the stopper 22 is fixed on the top surface 91 of the lower plate 90. In this embodiment, two stoppers 22 are respectively disposed on the lateral sides of the second linear guide 20, and the distance between the two stoppers 22 is a limited distance that the upper plate 80 can horizontally translate relative to the lower plate 90. In the actual moving process, the driving member 40 drives the third slider 31 on the third linear guide 30 to move horizontally along the third linear guide 30, and the movement of the third slider 31 drives the connecting rod 50 located thereon to move, and in the moving process of the connecting rod 50, the first slider 11 connected thereto is driven to move along the setting direction of the first linear guide 10. When the first sliding block 11 moves, the upper plate 80 fixed thereon is driven to move along the arrangement direction of the first linear guide 10, and simultaneously the second sliding block 21 on the second linear guide 20 moves along the arrangement direction of the second linear guide 20 along with the movement of the upper plate 80. When the second slider 21 moves to the side of the stopper 22 and abuts against it, the stopper 22 can limit the second slider 21 from moving further, so that the operation is reversed, the upper plate 80 is forced to stop the horizontal movement with respect to the lower plate 90, and the stopper 22 can precisely control the distance that the upper plate 80 can move on the lower plate 90.

Further, as shown in fig. 1 to 4, in the horizontal driving assembly 100 of the present invention, the driving element 40 located on the bottom surface 92 of the lower plate 90 is a driving cylinder 41 fixed on the bottom surface 92 of the lower plate 90, and the driving cylinder 41 is provided with a moving block 42. The driving cylinder 41 has the advantages of simple structure, convenience in installation and stable driving effect.
