[0017] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0018] Example 1: A processing mold for a Hall element fixture, wherein the Hall element includes: a Hall integrated circuit board 101 and an adhesive layer 102 covering the outside of the Hall integrated circuit board 101, the adhesive layer 102 has at least one mounting hole 103 with threads on the inner wall, and at least one sleeve 12 with internal threads is embedded in the adhesive layer 102, thereby forming the mounting hole 103 with threads on the inner wall; the potting fixture includes: a horizontally arranged base plate 5 and a first side plate 1, a second side plate 2, a third side plate 3, and a fourth side plate 4 that are vertically arranged and respectively in close contact with the upper surface of the base plate 5;

[0019] The first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 are arranged in sequence and tightly connected to each other, thereby forming a semi-enclosed cavity 6 with the base plate 5, which can accommodate the Hall integrated circuit board 101. At least one internally threaded pin sleeve 13 corresponding to the sleeve 12 is embedded and installed on the inner surface of the second side plate 2 facing the semi-enclosed cavity 6. The other end of the internally threaded pin sleeve 13, which is connected to the second side plate 2 at one end, extends into the semi-enclosed cavity 6. At least one support screw 14 corresponding to the sleeve 12 is installed on the fourth side plate 4, which is parallel to and opposite to the second side plate 2.

The sleeve 12 is fitted on the outside of the support screw 14 and is located between the inner surface of the fourth side plate 4 facing the semi-enclosed cavity 6 and the internally threaded pin sleeve 13.

[0020] A washer 15 is fitted on the outside of the aforementioned support screw 14 and between the sleeve 12 and the internal threaded pin sleeve 13; one end of the aforementioned internal threaded pin sleeve 13 is embedded in the second side plate 2 and is fixedly connected to the second side plate 2 by a fastening screw 131 embedded in the second side plate 2.

[0021] Example 2: A processing mold for a Hall element fixture, the Hall element comprising: a Hall integrated circuit board 101 and an adhesive layer 102 covering the outside of the Hall integrated circuit board 101, the adhesive layer 102 having at least one mounting hole 103 with threads on the inner wall, at least one sleeve 12 with internal threads embedded in the adhesive layer 102, thereby forming the mounting hole 103 with threads on the inner wall, the mounting channel of the Hall element is reinforced by adding the sleeve, the potting fixture comprising: a horizontally arranged base plate 5 and vertically arranged first side plate 1, second side plate 2, third side plate 3, and fourth side plate 4, the potting fixture comprising: a horizontally arranged base plate 5 and vertically arranged first side plate 1, second side plate 2, third side plate 3, and fourth side plate 4 respectively in close contact with the upper surface of the base plate 5;

[0022] The first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4, arranged in sequence, are tightly connected in pairs, thereby forming a semi-enclosed cavity 6 with the base plate 5, into which the Hall integrated circuit board 101 can be placed. At least one internally threaded pin sleeve 13 corresponding to the sleeve 12 is embedded and installed on the inner surface of the second side plate 2 facing the semi-enclosed cavity 6. The other end of the internally threaded pin sleeve 13, which is connected to the second side plate 2 at one end, extends into the semi-enclosed cavity 6. At least one support screw 14 corresponding to the sleeve 12 is installed on the fourth side plate 4, which is parallel to and opposite to the second side plate 2. The support screw 14 passes through the fourth side plate 4 and is threadedly connected to the internally threaded pin sleeve 13 in the semi-enclosed cavity 6. The sleeve 12 is fitted on the outside of the support screw 14 and is located on the inner surface of the fourth side plate 4 facing the semi-enclosed cavity 6 between the internally threaded pin sleeve 13 and the internally threaded pin sleeve 13.

[0023] The fourth side plate 4 is provided with a countersunk hole 41 on the outer surface of the semi-enclosed cavity 6 opposite to the fourth side plate 4, for the cap part of the supporting screw 14 to be inserted.

[0024] The first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 are all fixedly connected to the base plate 5 by vertical bolts 91; the first side plate 1 and the third side plate 3, which are arranged in parallel opposite directions, are fixedly connected by two horizontal bolts 92 that pass through the second side plate 2 and the third side plate 3 respectively.

[0025] In use, the Hall integrated circuit board is installed on the inside of the first side plate while maintaining the gap between the Hall integrated circuit board and the inner surface of the first side plate;

[0026] At least one internally threaded pin is mounted at one end on the inner surface of the second side plate and at the other end protrudes from the inner surface of the second side plate.

[0027] At least one support screw, corresponding to the internal threaded pin sleeve, extends from the outer surface of the fourth side plate through the fourth side plate toward its inner side. At least one sleeve is fitted onto the outer side of the support screw, and then the support screw is threadedly locked to the internal threaded pin sleeve on the second side plate, so that the sleeve is limited between the inner surface of the fourth side plate and the internal threaded pin sleeve, and the fourth side plate and the second side plate are connected by the support screw and the internal threaded pin sleeve.

[0028] The lower end of the first side plate is tightly installed on the upper surface of the base plate. Then, the lower ends of the second and fourth side plates, which are connected to each other, are tightly installed on the upper surface of the base plate. At this time, the first side plate is connected between one end of the second and fourth side plates. Then, the third side plate is placed between the other end of the second and fourth side plates and the lower end of the third side plate is tightly installed on the upper surface of the base plate. Then, the second and fourth side plates are tightly connected to the first and third side plates on their outer ends, respectively. Thus, a semi-closed cavity for glue injection is formed between the first, second, third, and fourth side plates and the base plate, which are tightly connected in pairs. The Hall integrated circuit board installed on the inner side of the first side plate, the internal threaded pin sleeve installed on the inner surface of the second side plate, and the sleeve fitted on the outer side of the support screw are all located in the semi-closed cavity.

[0029] Encapsulating adhesive is injected into the semi-enclosed cavity, and after molding and cooling, the element is demolded to obtain the Hall element.

[0030] The above embodiments are further explained as follows:

[0031] The internal cavity design of the fixture enables the Hall element to function while also allowing for convenient installation.

[0032] The structure is semi-enclosed, with only the top glue inlet reserved. All other components are tightly joined together, and the Hall element is fixed in shape using traditional screw locking. Furthermore, the height of the fixture plates on the front, back, left, and right sides of the Hall element is the same as the length of the Hall element, ensuring the distance between the finished product and the linear motor actuator.

[0033] It can be fixed with just screws, and the fixture is flexible, convenient and low cost; the surface fit between each fixture plate ensures the overall dimensional accuracy of the Hall element; the height of the fixture plate ensures the total length of the Hall element and avoids interference with the mover wire outlet.

[0034] The overall structure is simple, compact, and reliable. The entire fixture can be directly placed into the dispensing machine for dispensing, which is convenient for personnel to operate. The groove-free structure makes it easy to demold, and it will not cause the Hall element to be difficult to demold. The dispensing process can be completed in one step without secondary processing, reducing steps and saving time.

[0035] When the processed Hall element is installed, the screw is fixed to the end face of the sleeve, which can avoid the screw from contacting the adhesive surface of the Hall element, thus ensuring its shape and aesthetics. When the Hall element is installed on the mover, it can be tightened more tightly without affecting the shape of the Hall element.

[0036] When using the above-mentioned Hall element tooling processing mold, a threaded hole is formed by an inner nested cylinder, and a countersunk hole is formed on the outside of the threaded hole to facilitate the connection of the Hall element. This replaces the method of directly setting the threaded hole on the rubber layer, which simplifies the processing technology and improves the rigidity of the threaded surface, thereby ensuring the stability of the connection structure.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
