[0027] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features.

In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0028] A circuit board fixture for an automobile thermostat comprises a motor 1 and a fixture body.

[0029] The fixture body includes a bottom plate 2, two x-direction support plates 4, two y-direction support plates 5, four clamping blocks 6 and a replaceable positioning plate 7. The left and right sides of the bottom plate 2 are both provided with first slide grooves 21, and the two first slide grooves 21 are arranged in parallel. The front and rear sides of the bottom plate 2 are both provided with second slide grooves 22, and the two second slide grooves 22 are arranged in parallel. The first slide groove 21 and the second slide groove 22 are arranged vertically.

[0030] The x-direction support plate 4 is arranged parallel to the second slide groove 22, and the two ends of the x-direction support plate 4 are slidably matched with the two first slide grooves 21 through the locking piece 3 respectively. The x-direction support plate 4 is provided with an x-direction slide groove 41, and the x-direction slide groove 41 is parallel to the x-direction support plate 4.

[0031] The y-direction support plate 5 is arranged parallel to the first slide groove 21, and the two ends of the y-direction support plate 5 are slidably matched with the two second slide grooves 22 through the locking piece 3 respectively. The y-direction support plate 5 is provided with a y-direction slide groove 51, and the y-direction slide groove 51 is parallel to the y-direction support plate 5.

[0032] Slide bars 8 are provided at the intersection of the x-direction support plate 4 and the y-direction support plate 5. The slide bars 8 are respectively slidably matched with the corresponding x-direction slide grooves 41 and y-direction slide grooves 51. Clamp blocks 6 are provided on the tops of the slide bars 8. The clamp blocks 6 are all L-shaped, and the end extension lines of the four clamp blocks 6 are connected in pairs to form a square. The outer sides of the tops of the clamp blocks 6 are provided with stop convexities 61, so that the inner sides of the clamp blocks 6 form support grooves 62 for clamping circuit boards.

[0033] This embodiment can position circuit boards of different sizes by adjusting the distance between the clamping blocks 6, thereby improving the versatility of the positioning fixture.

[0034] In addition, the inner side walls of the clamping blocks 6 are all provided with slots 63, the positioning plate 7 is provided between the four clamping blocks 6, and the four corners of the positioning plate 7 are respectively inserted into the four slots 63. The top of the positioning plate 7 is provided with a plurality of positioning posts 71 matching the circuit board.

[0035] By replacing the positioning plate 7 of the corresponding circuit board, different circuit boards can be positioned by positioning posts 71 of different shapes and sizes, thereby positioning the circuit board more stably.

[0036] A plurality of profiling grooves 64 are provided on one side of the stop 61 near the support groove 62, and two clamping blocks 65 are provided in each of the profiling grooves 64. Both clamping blocks 65 can slide parallel to the extension direction of the clamping block 6, and the two clamping blocks 65 are respectively used to clamp the two sides of the protruding portion of the edge of the circuit board.

[0038] Generally, the jig for placing the circuit board cannot be moved, and the dispensing equipment needs to move along the xy axis, which is inefficient and prone to errors. Therefore, the motor 1 is set at the bottom of the base plate 2 to drive the base plate 2 to rotate horizontally. By setting the motor 1 to drive the jig to rotate, the movement of the xy axis of the dispensing device can be reduced, thereby improving production efficiency.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
