DETAILED DESCRIPTION

[0037] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0039] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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.

[0040] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0041] In one embodiment, an assembly system for an FPC with a Hall element is described, which is capable of installing a flexible circuit board on a first positioning mechanism 1 and a second positioning mechanism 2, and through the cooperation of a connecting seat 14 and a positioning seat 32, the flexible circuit board is located above the workpiece, and the first positioning mechanism 1 and the second positioning mechanism 2 are separated from the flexible circuit board, so that the flexible circuit board is assembled on the workpiece located on a product carrier 3.

[0042] Specifically, see the attached drawings of the specification Figures 1 to 4 , an assembly system for an FPC with a Hall element includes a product carrier 3, a first positioning mechanism 1 and a second positioning mechanism 2, wherein the first positioning mechanism 1 is arranged at one end of the second positioning mechanism 2, and the Hall end of the flexible circuit board is suitable for connecting and cooperating with the side of the first positioning mechanism 1 away from the second positioning mechanism 2, and the Hall end is detachably arranged on the first positioning mechanism 1. Correspondingly, the circuit board end of the flexible circuit board is suitable for connecting and cooperating with the lower end surface of the second positioning mechanism 2, so that the circuit board end is detachably arranged on the lower end surface of the second positioning mechanism 2. In this way, the clamping and fixing of the FPC with a Hall element can be realized, without the need for the staff to clamp the flexible circuit board manually or with tweezers, with high precision, and not easy to fall off and cause damage.

[0043] It can be understood that the first positioning mechanism 1 and the second positioning mechanism 2 are connected in sequence, the Hall end is set at the end of the first positioning mechanism 1 away from the second positioning mechanism 2, and the flexible circuit board is bent so that the circuit board end can be fixed on the lower end surface of the second positioning mechanism 2, so that the flexible circuit board is L-shaped when installed on the first positioning mechanism 1 and the second positioning mechanism 2.

[0044] The upper end surface of the product carrier 3 is configured to place the workpiece so that the workpiece is set on the upper end surface of the product carrier 3, and a positioning seat 32 is provided on the upper end surface of the product carrier 3, and the positioning seat 32 is suitable for snap-fitting with the connecting seat 14, so that the first positioning mechanism 1 can be detachably set on the positioning seat 32, when the positioning seat 32 is snap-fitted with the connecting seat 14, the first positioning mechanism 1, the second positioning mechanism 2 and the flexible circuit board can be set above the workpiece, and then the first positioning mechanism 1, the second positioning mechanism 2 are separated from the flexible circuit board, and then the flexible circuit board is assembled on the workpiece.

[0045] It should be noted that the Hall element is arranged at one end of the flexible circuit board to form a Hall end, and the other end of the flexible circuit board forms a circuit board end. The workpiece is L-shaped, and when the workpiece is placed on the product carrier 3, one end of the workpiece abuts against the positioning seat 32, and the lower end surface of the workpiece is connected to the upper end surface of the product carrier 3.

[0046] In this embodiment, the first positioning mechanism 1 and the second positioning mechanism 2 are connected and fixed to the Hall end and the circuit board end respectively, so as to realize multi-point connection and fixation of the FPC with the Hall element. It should be pointed out that the lower end surface of the flexible circuit board is provided with a backing adhesive, and when the connecting seat 14 is engaged with the positioning seat 32, the backing adhesive can be bonded and matched with the workpiece. Moreover, the Hall end and the first positioning mechanism 1 are detachably connected, and the circuit board end and the second positioning mechanism 2 are detachably connected, so that the flexible circuit board can be separated from the first positioning mechanism 1 and the second positioning mechanism 2, and then the flexible circuit board can be installed on the workpiece.

[0047] In one embodiment, this embodiment further describes the first positioning mechanism 1. The first positioning mechanism 1 includes a first vacuum nozzle 13. A first flow channel connected to the first vacuum nozzle 13 is provided in the first positioning mechanism 1, and an end of the first flow channel away from the first vacuum nozzle 13 is opened on a side of the mounting seat 12 away from the second positioning mechanism 2. The first vacuum nozzle 13 generates suction, and then the Hall end is adsorbed on the mounting seat 12, that is, the Hall end is adsorbed on the side wall of the end of the mounting seat 12 away from the second positioning mechanism 2.

[0048] It is understandable that the first vacuum nozzle 13 is set to suck air into the first vacuum nozzle 13, so that the suction force generated by the first vacuum nozzle 13 is adsorbed on the Hall end, thereby achieving the connection and fixation between the Hall end and the mounting seat 12. Moreover, the two can be separated conveniently by only stopping the first vacuum nozzle 13 from sucking air, and the first flow channel does not generate suction, and the Hall end can be separated from the mounting seat 12.

[0049] In one embodiment, this embodiment further describes the first positioning mechanism 1. It also includes a pin assembly 11 arranged on a mounting seat 12, the mounting seat 12 is arranged at one end of the second positioning mechanism 2, a receiving space matched with the pin assembly 11 is arranged in the mounting seat 12, and the pin assembly 11 is movably arranged in the receiving space. A through hole is arranged at one end of the mounting seat 12 away from the second positioning mechanism 2, and the through hole is connected to the receiving space. When the pin assembly 11 is arranged in the receiving space, one end of the pin assembly 11 extends out from the receiving space through the through hole.

[0050] Correspondingly, the Hall end is provided with a through hole matched with one end of the pin assembly 11, and the Hall end is sleeved on the outer side of one end of the pin assembly 11 through the through hole, so that the Hall end is arranged on the side of the mounting seat 12 away from one end of the second positioning mechanism 2. Correspondingly, when the connecting seat 14 is engaged with the positioning seat 32, one end of the pin assembly 11 and the end of the workpiece connected to the positioning seat 32 are in contact and squeezed, driving the pin assembly 11 to move in the direction close to the second positioning mechanism 2, and the Hall end does not move, so that the Hall end is separated from one end of the pin assembly 11.

[0051] It can be understood that by arranging the pin assembly 11 and the first vacuum nozzle 13 to cooperate with each other, the connection strength and assembly accuracy between the Hall end and the mounting seat 12 are further improved. In addition, by contacting and squeezing one end of the pin assembly 11 with the end connected to the workpiece and the positioning seat 32, one end of the pin assembly 11 moves relative to the Hall end toward the direction close to the second positioning mechanism 2. During this process, the Hall end will not be affected, which can reduce the possibility of damage to the Hall end.

[0052] In one embodiment, this embodiment further describes the pin assembly 11, which includes an elastic member, a pin 111, and an extension portion arranged along the circumference of the pin 111. When the elastic member is sleeved on the outer side of the pin 111, one end of the elastic member abuts against the inner wall of the end of the accommodating space away from the through hole, and the other end of the elastic member abuts against the extension portion. Accordingly, the extension portion is suitable for limiting the through hole, so that one end of the pin extends out of the through hole, and the extension portion is prevented from extending out of the accommodating space.

[0053] When the positioning seat 32 is engaged with the connecting seat 14 , one end of the pin 111 is pressed by the workpiece, pushing the pin 111 to move, and the elastic member is compressed, so that one end of the pin 111 is separated from the Hall end.

[0054] Preferably, the elastic member is set as a spring, and a damping sleeve is set at one end of the pin 111 passing through the through hole to increase the friction between the pin 111 and the inner wall of the through hole, so that the pin 111 can remain motionless for a long time after moving, which is convenient for the Hall end to separate from the pin assembly. After the first positioning mechanism 1 and the second positioning mechanism 2 are separated from the flexible circuit board, the staff can move one end of the pulling pin assembly 11 away from the second positioning mechanism 2 to facilitate the installation of the next flexible circuit board.

[0055] See the attached drawings in the specification Figure 2 The mounting seat 12 includes a first support member, a connecting member and a second support member connected in sequence, and the first support member and the second support member are respectively vertically arranged at both ends of the length direction of the connecting member, so that the mounting seat is I-shaped to form an accommodating space between the first support member and the second support member. A through hole is opened on the first support member, and a through groove is provided on the second support member, so that one end of the pin 111 is located in the through hole and the other end is located in the through groove. One end of the elastic member abuts on the extension portion, and the other end abuts on the second support member.

[0056] Of course, in actual production applications, the mounting seat 12 may also adopt other forms to achieve the purpose of setting the pin assembly 11 on the mounting seat 12, which are not described one by one here and are all within the protection scope of the present utility model.

[0057] In one embodiment, this embodiment provides another specific form of the first positioning mechanism 1. In this embodiment, the first positioning mechanism 1 is provided with a first vacuum nozzle 13, and no pin assembly 11 is provided. The end of the mounting seat 12 away from the second positioning mechanism 2 is provided with a limiting groove matched with the Hall end. When the flexible circuit board is matched with the mounting device, the Hall end can be set in the limiting groove, and the end of the first flow channel away from the first vacuum nozzle 13 is opened on the inner wall of the limiting groove.

[0058] The limiting groove is slightly larger than the Hall end so that the Hall end can be installed in the limiting groove. In addition, the suction force generated by the first vacuum suction nozzle 13 can adsorb the Hall end in the limiting groove.

[0059] Of course, in actual production applications, there are many forms of the first positioning mechanism 1, which are not described one by one here, and are all within the protection scope of the present utility model.

[0060] In one embodiment, referring to the accompanying drawings, Figure 2 This embodiment further illustrates the connecting seat 14, wherein a positioning assembly suitable for snap-fitting with the positioning seat 32 is provided on the connecting seat 14, and the connecting seat 14 and the positioning seat 32 are snap-fitted to set the first positioning mechanism 1, the second positioning mechanism 2 and the flexible circuit board above the workpiece.

[0061] The positioning assembly includes a positioning pin 141 and a positioning hole provided on the positioning seat 32. At least two positioning pins 141 are provided, and the positioning pins 141 are provided at one end of the mounting seat 12 away from the second positioning mechanism 2 and engage with the positioning hole to set the connecting seat 14 on the positioning seat 32.

[0062] Of course, in actual production applications, the positioning assembly can also be provided with a magnetic attraction component, by providing a magnet on the side where the positioning seat 32 and the connecting seat 14 are close to each other, the connection and cooperation between the connecting seat 14 and the positioning seat 32 can be achieved through the attraction of opposite charges of the magnets.

[0063] In one embodiment, referring to the accompanying drawings, Figure 2 , this embodiment further describes the second positioning mechanism 2. The second positioning mechanism 2 includes a limiting plate 21 and a plurality of second vacuum nozzles 22. The limiting plate 21 is provided with a second flow channel that matches the second vacuum nozzle 22. The second vacuum nozzle 22 is connected to the second flow channel to adsorb the circuit board end on the lower end surface of the limiting plate 21.

[0064] Furthermore, a mounting groove 211 matching with the end of the circuit board is provided on the lower end surface of the limiting plate 21 , and one end of the second flow channel is opened on the top wall of the mounting groove 211 .

[0065] When in use, the circuit board end of the flexible circuit board is sucked and set in the installation groove 211, and gas is injected into the second vacuum suction nozzle 22, so that the suction force generated by the second vacuum suction nozzle 22 is transmitted to the circuit board end in the installation groove 211 through the second flow channel, and then the circuit board end is sucked and fixed on the lower end surface of the limit plate 21. After the second vacuum suction nozzle 22 is cut off, the second vacuum suction nozzle 22 does not generate suction, and the circuit board end automatically falls off from the second positioning mechanism 2.

[0066] Further, see the accompanying drawings of the specification Figure 4The product carrier 3 also includes a plurality of clamping blocks 33 arranged on the upper end surface of the carrier body 31, and the plurality of clamping blocks 33 are arranged along the circumference of the carrier body 31 to form a clamping space for clamping the workpiece between the clamping blocks 33, the positioning seat 32 and the carrier body 31.

[0067] Specifically, in this embodiment, the Hall end of the flexible circuit board is set on the side of the first positioning mechanism away from the second positioning mechanism 2 through the pin assembly 11, and the staff bends the flexible circuit board so that the flexible circuit board is bent at the connection between the Hall end and the circuit board end, and then the circuit board end is set in the mounting groove 211 below the limit plate 21. Then the second vacuum suction nozzle 22 is opened to generate vacuum suction on the circuit board end, and the first vacuum suction nozzle 13 is opened to generate suction on the Hall end, and then the flexible circuit board is set on the mounting device. After the flexible circuit board is installed on the first positioning mechanism 1 and the second positioning mechanism 2, the workpiece is installed on the product carrier 3, and the staff inserts the positioning pin 141 of the connecting seat 14 into the positioning hole on the positioning seat 32 on the product carrier 3, and then the first positioning mechanism 1, the second positioning mechanism 2 and the FPC with the Hall element are positioned above the workpiece. It can be understood that after the positioning pin 141 is inserted into the positioning hole on the positioning seat 32 on the product carrier 3, the FPC with the Hall element is provided with adhesive, and the FPC with the Hall element is fixed to the workpiece by adhesive bonding. One end of the pin assembly 11 is pressed by the workpiece to separate the pin assembly 11 from the Hall end, and then the first vacuum nozzle 13 and the second vacuum nozzle 22 are cut off to separate the flexible circuit board from the first positioning mechanism 1 and the second positioning mechanism 2.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
