Description

Technical Field

[0001] The utility model relates to the technical field of ear thermometer production, and particularly relates to a positioning device for an ear thermometer shell. Background Art

[0002] During the production process of ear thermometers, it is a key process to fix the unit PCB circuit board at the corresponding position of the ear thermometer by screwing. The purpose is to ensure that the unit PCB circuit board does not shift in relative position during use. In the existing production process, workers usually take the ear thermometer shell and the unit PCB circuit board to perform the screwing operation. However, manual operation has low efficiency and it is difficult to ensure the stability of the screwing quality. If using a machine for operation, but in the existing technology, there is a lack of precise positioning for the special-shaped size of the ear thermometer, which easily causes jitter during the screwing operation, resulting in displacement between the unit PCB circuit board and the ear thermometer shell, thus reducing the quality and efficiency of screwing, increasing the defective rate of products, and affecting the integrity and appearance of the ear thermometer.

[0003] With the rapid development of the electronic manufacturing industry, higher requirements are put forward for the accuracy, flexibility, and operation convenience of the ear thermometer shell positioning device. Therefore, a new type of ear thermometer shell positioning device is needed to solve the problems existing in the prior art. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a positioning device for an ear thermometer shell. The positioning device realizes the precise positioning of the ear thermometer shell through the cooperation of the operation part, the linkage part and the limiting part, as well as the elastic action of the elastic part, reduces the labor cost, and improves the operation efficiency.

[0005] The technical solution of the utility model is realized as follows:

[0006] A positioning device for an ear thermometer shell, comprising a base, a tray and a limiting component. The tray is arranged on the base, and a plurality of placement areas for placing the ear thermometer shell are arranged side by side on the tray. The tray is also provided with an avoidance hole, and the limiting component is slidably arranged on the tray. The limiting component includes a linkage part, an operation part and a limiting part that moves in the avoidance hole. The limiting part includes a sliding seat and a pressing part, and the operation part is connected with the sliding seat through the linkage part. The operation part is located beside the tray, and an elastic part is arranged between the tray and the operation part. The avoidance hole is located beside the placement area, the sliding seat is slidably arranged in the avoidance hole, and the pressing part is located above the placement area and is configured to position the ear thermometer shell. When the operation part is pressed, the sliding seat moves in the avoidance hole and the pressing part leaves above the placement area; the elastic part acts on the operation part so that when the pressing force disappears, it drives the operation part and the limiting part to reset through its own elastic force.

[0007] Preferably, the size and shape of the placement area are matched with the housing of the ear thermometer to improve the accuracy and stability of positioning.

[0008] Preferably, a sliding groove is provided on the bottom surface of the tray along the arrangement direction of the placement area, and the linkage is a long rod, the end of the long rod exposed from the tray is connected to the operating part, the sliding seats are evenly connected to the long rod, and each sliding seat is arranged perpendicular to the long rod and the head of the upper end of the sliding seat is exposed in the corresponding avoidance hole, and the pressing piece extends laterally to the side of the head of the sliding seat.

[0009] Through the above design, the long rod is used as a linkage member, so that all the sliding seats can move synchronously. When the operating part is pressed, the long rod can evenly transfer the force to each sliding seat, so that all the pressing members can synchronously leave the top of the placement area. Similarly, when the pressing force disappears, the elastic force of the elastic member can also synchronously return each pressing member to the top of the placement area for positioning through the long rod, which greatly improves the convenience and efficiency of operation. The sliding seat is evenly connected to the long rod, which can ensure that the force of the pressing member above each placement area on the ear thermometer housing is relatively uniform. In this way, the ear thermometer housing can be prevented from being offset or tilted during the positioning process due to uneven force, ensuring the accuracy of positioning. Each sliding seat is arranged perpendicular to the long rod and the head of the upper end of the sliding seat is exposed in the corresponding avoidance hole, so that the sliding of the sliding seat in the avoidance hole is more stable. The head of the upper end of the sliding seat is exposed in the corresponding avoidance hole, providing stable support for the pressing member. This structural design can reduce the shaking of the sliding seat during operation, thereby improving the stability of the entire positioning device.

[0010] Preferably, the elastic member is a compression spring with good elastic properties. One end of the compression spring abuts against the tray, and the other end of the compression spring abuts against the operating part, which plays a stabilizing role during the operation. When the operating part is in action, the elastic force of the compression spring can balance part of the operating force, absorb the vibration and impact force generated during the operation, make the operation more stable, and improve the accuracy and reliability of the operation.

[0011] Preferably, the pressing piece is a rod-shaped piece, and the connection with the sliding seat is an interference fit or a detachable connection is achieved by fasteners. For some special shapes of ear thermometer housings, a rod-shaped pressing piece of appropriate length and thickness can be selected to ensure that the housing can be accurately positioned, thereby improving the versatility and adaptability of the device. The interference fit connection method allows the pressing piece to maintain a stable connection during normal use and is not easy to loosen; the fastener connection method provides more options for replacing the pressing piece, and different types of fasteners, such as screws, nuts, etc., can be selected according to actual needs to meet different connection strength and disassembly frequency requirements.

[0012] Preferably, the linkage member and the operating portion are connected via screws to facilitate installation and disassembly.

[0013] Preferably, the tray and the base are detachably connected by bolts, so as to facilitate maintenance and replacement of trays of different specifications to accommodate different models of ear thermometer housings.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The purpose of the utility model is to provide an ear thermometer housing positioning device. Compared with the prior art, the shape and size of the placement area of the device are adapted to the ear thermometer housing, so that even a special-shaped ear thermometer can be stably placed in the placement area, reducing the displacement caused by the machine shaking during the screwing process, ensuring the accuracy of positioning, and helping to improve product quality. A plurality of placement areas are arranged side by side on the tray of the device, and a plurality of ear thermometer housings can be positioned. Compared with manual operation, the labor cost is greatly reduced and the production efficiency is improved. During operation, the operator only needs to press the operating part to drive the sliding seat to move in the avoidance hole through the linkage part, so that the pressing part leaves the top of the placement area to provide enough space for the ear thermometer housing to be placed. When the operating part is reset under the action of the elastic part, the pressing part returns to the top of the placement area and presses against the edge of the ear thermometer housing to achieve the purpose of positioning.

[0016] In addition, when the device is in use, the operator can operate on one side of the pallet, without having to perform complicated operations at multiple locations on the pallet, which makes the operating space more reasonable and reduces interference factors during the operation.

Detailed implementation manners

[0023] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0025] The specific implementation manners of the present utility model are as follows:

[0026] As Figure 1 shown, an embodiment of the present utility model provides an ear thermometer housing positioning device, including a base 1, a tray 2 and a limiting component 5. The tray 2 is arranged on the base 1. In this embodiment, five placement areas 3 for placing the ear thermometer housing 21 are arranged side by side on the tray 2. The placement areas 3 are concave groove-shaped, and their sizes and shapes are adapted to the ear thermometer housing 21, which can better place the ear thermometer housing.

[0027] As Figure 2 , 3 , 4 shown, the limiting component 5 is slidably arranged on the tray. The limiting component 5 includes a linkage member 10, an operating portion 6 and a limiting member 7 that moves in an avoidance hole 4. The limiting member 7 includes a sliding seat 7a and a pressing member 8. The operating portion 6 is connected to the sliding seat 7a through the linkage member 10. The operating portion 6 is located beside the tray 2. An elastic member 9 is arranged between the tray 2 and the operating portion 6. The elastic member 9 is a compression spring. The tray 2 is also provided with an avoidance hole 4. The avoidance hole 4 is located beside the placement area 3 and penetrates through the tray 2 up and down. During installation, the linkage member 10 is placed in the sliding groove 11, and the operating portion 6, the sliding seat 7a and the pressing member 8 are inserted into the avoidance holes at corresponding positions. The pressing member 8 is fixed on the sliding seat 7a by interference fit or fastener connection. The pressing member 8 is located above the placement area 3 and is configured to position the ear thermometer housing 21.

[0028] When the operating portion 6 is pressed, the sliding seat 7a moves in the avoidance hole 4 and the pressing member 8 leaves above the placement area 3. At this time, the ear thermometer housing 21 can be placed in the placement area 3 or taken out from the placement area 3. After releasing the operating portion, under the action of the elastic member 9, the sliding seat 7a moves in the avoidance hole 4, and the pressing member 8 returns above the placement area 3 to position the ear thermometer housing 21.

[0029] In actual operation, first, the operator gently presses the operation part 6. At this time, after the operation part 6 is stressed, it drives the sliding seat 7a to move in the avoidance hole through the linkage part 10. As the sliding seat 7a moves, the pressing part 8 will also move away from above the placement area 3, thus providing enough space for the insertion of the ear thermometer housing 21.

[0030] Then, the ear thermometer housings 21 are inserted into the placement area 3 one by one. Since the size and shape of the placement area 3 match those of the ear thermometer housing 21, the ear thermometer housing 21 can be stably placed in the placement area 3 without shaking.

[0031] After the ear thermometer housings 21 are placed, a positioning operation is carried out. When all the ear thermometer housings 21 are inserted, the operation part 6 is released. Under the action of the elastic part 9, the operation part 6 resets, and at the same time, the linkage part 10 drives the sliding seat 7a, so that the pressing part 8 returns above the placement area 3 to accurately position the ear thermometer housing 21.

[0032] As Figure 5 shown, after the ear thermometer housing 21 is positioned, a screwing operation is carried out. The base 1 with the positioned ear thermometer housing 21 is placed on the XY rails on the machine table surface. The XY rails have corresponding drives in their respective directions, so that the base 1 can move horizontally along the XY directions under program control. At the same time, the cooperating screw operating head 24 moves vertically above to carry out a screwing operation on the threaded hole 23 on the unit PCB circuit board 22. Since the ear thermometer housing 21 is firmly fixed by the positioning device, it will not be displaced during the screwing process, thus ensuring the quality and efficiency of the screwing operation.

[0033] In the actual use process, if it is necessary to position ear thermometer housings 21 of different models, it can be achieved by replacing the tray 2. The tray 2 and the base 1 are detachably connected by bolts, which is convenient and fast to operate. The linkage part 10 is a long rod made of plastic and can stably transmit force. The sliding seats 7a are evenly connected to the long rod, ensuring the synchronism and stability of the operation. The pressing part 8 is a rod-shaped part made of metal, and appropriate lengths and thicknesses can be selected according to different ear thermometer housings 21, and it is connected to the sliding seat by interference fit or fasteners, which is convenient for replacement and adjustment. The elastic part 9 is a compression spring made of high-strength spring material and can provide stable elastic force to ensure the smoothness and accuracy of the operation. Each component of the whole device cooperates with each other to provide an efficient and accurate solution for the positioning and screwing operations of the ear thermometer housing 21.

[0034] The above has schematically described the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
