[0002] In the production process of a thermometer, the incoming PCB panels for the thermometer are usually in a continuous strip form, which is beneficial to the processing and manufacturing of the PCB panels. However, since each thermometer actually only requires one unit of PCB board, after the PCB has completed all the processing procedures, the PCB panel must be divided into individual PCB units, and this operation requires folding plate treatment. The traditional PCB folding method usually relies on manual folding, which not only has low efficiency, but also easily causes problems such as inaccurate folding positions and damage to the PCB. In addition, the consistency and stability of manual folding are poor, and it is difficult to meet the requirements of high-efficiency production.

[0003] Therefore, in order to solve the problems existing in the existing manual PCB folding technology, it is of great practical significance and application value to develop a PCB panel auxiliary folding device with a simple structure, convenient operation, strong adaptability and high efficiency to effectively ensure the folding quality.

Detailed Description of the Preferred Embodiment

[0030] 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 drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0031] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can 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.

[0032] The specific implementation manner of the present utility model is as follows:

[0033] As Figures 1-4 shown, the present utility model provides a PCB panel auxiliary folding device, including a base 1 and a folding component 2. The folding component 2 has an upper folding part 21 and a lower folding part 22. The upper folding part 22 is movably connected to a suspension rod 24 through a connecting disk 23, and the suspension rod 24 is connected to a bracket 25 through a driving device, and the driving mechanism can be one of a lead screw nut mechanism, a cylinder or a mechanical handle; the bracket 25 is fixedly connected to a vertical rod 11, and the vertical rod is fixedly installed on the base 1; and the lower folding part 22 is movably connected to the base 1 through a key 7 at its lower end; when the upper folding part 21 moves downward, the present device realizes the purpose of breaking the PCB panel by the staggered extrusion of the supporting teeth 13a and the tooth teeth 12a.

[0034] As Figure 2 、 3 、4, 6, 7 shown, a plurality of pressing teeth 12 are evenly arranged along the left - right direction at the lower end of the upper folding part 21, and a plurality of supporting teeth 13 are evenly arranged along the left - right direction at the upper end of the lower folding part 22, and the pressing teeth 12 and the supporting teeth 13 are arranged in a staggered manner. The lower end of the pressing tooth 12 on the upper folding part 21 forms a tooth tooth 12a for correspondingly pressing and breaking the connection point 26 of the PCB panel, and the upper end of the supporting tooth 13 on the lower folding part 22 forms a supporting tooth 13a for correspondingly supporting the connection point 26 of the PCB panel. The pressing teeth 12 on the upper folding part 21, the supporting teeth 13 on the lower folding part 22 correspond to the respective connection points 26 of the PCB panel. In the left - right direction, the distance between two adjacent tooth teeth is equal to the width of two adjacent PCB unit boards; similarly, the distance between two adjacent supporting teeth is also equal to the width of two adjacent PCB unit boards. So that the tooth tooth 12a at the tip of each pressing tooth 12 of the upper folding part 21 is in the middle position between two adjacent supporting teeth 13 of the lower folding part 22, and the supporting tooth 13a at the tip of each supporting tooth 13 of the lower folding part 22 is in the middle position between two adjacent pressing teeth 12 of the upper folding board 21.

[0035] As Figure 3 shown, the upper folding part 21 is connected to the suspension rod 24 through a connecting disk 24, with stable connection and convenient for installation and disassembly. The pressing teeth 12 of the upper folding part 21 are in a set of front and rear. When different - sized PCB panels need to be processed, the upper folding part 21 needs to be replaced. The upper folding part can be replaced by loosening the bolts through the threaded holes on the upper surface of the upper folding part and the through holes of the disk cover at the lower end of the suspension rod 24 to meet the processing requirements of different - sized PCB panels.

[0036] As Figure 4As shown in the figure, a positioning structure 5 is provided between the lower folding plate component 22 and the base 1. The positioning structure includes a keyway 6 on the base 1 and a key 7 at the lower end of the lower folding plate component 22. A positioning structure 4 for fixing the position of the PCB panel is provided on the lower folding plate component 22. The positioning structure 4 is a protrusion protruding from the left and right ends of the lower folding plate component 22, and the distance between the two protrusions is equal to the length of the PCB panel. When processing PCB panels of different sizes, it is necessary to replace the lower folding plate component 22. The key 7 at the lower end of the lower folding plate component 22 can be taken out from the keyway 7, and then the lower folding plate component 22 of different sizes can be replaced to ensure that the device can adapt to the processing of PCB panels of different specifications.

[0037] During use, first select the appropriate upper folding plate component 21 and lower folding plate component 22 according to the size of the PCB panel for installation. Then place the PCB panel between the upper folding plate component 21 and the lower folding plate component 22, so that the teeth of the upper and lower folding plate assemblies correspond to the break connection points 26 of the PCB panel. Finally, the up and down movement of the suspension rod drives the connection plate locked with its lower end by bolts and the upper folding plate component 21 to move up and down. The teeth of the pressing teeth at its lower end and the lifting teeth 13a of the supporting teeth 13 on the lower folding plate component 22 are alternately pressed against the break connection point 26 of the PCB panel to complete the breaking operation of the PCB panel.

[0038] The PCB panel auxiliary folding device of the present utility model can accurately and efficiently complete the breaking and separating work of the PCB panel through the coordinated action of various components, and has good practicability and wide applicability.

[0039] The above schematically describes the present utility model and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
