Description

Technical Field

[0001] The utility model relates to the field of SMT patch processing, in particular to a measuring device used for SMT patch processing. Background Art

[0002] SMT patch refers to the abbreviation of a series of process flows based on PCB, which is mainly used for surface mounting and welding of electronic components.

[0003] A Chinese patent discloses a measuring device for SMT patch processing (authorization announcement number CN 220568089U). This patented technology can solve the problem that the existing SMT patch processing measuring device needs to be manually moved and observed during installation and use, which not only reduces work efficiency but also may cause damage to the patch.

[0004] The existing SMT patch is usually measured by manual control during rotation. If the force is too strong and the rotation speed is too fast, the SMT patch may fall off. In addition, when the SMT patch is clamped, the clamping degree cannot be judged, which may cause damage to the side wall of the SMT patch. Utility Model Content

[0006] Preferably: a control panel is installed on the front end surface of the base, and the control panel is electrically connected to the regulating motor.

[0007] Preferably, a positioning groove is provided at the inner end of the limiting frame, and the positioning groove is a square structure.

[0008] Preferably, a plurality of pressure sensing units are installed on the inner end of the positioning groove from top to bottom, and a warning light is installed on the outer end surface of the limiting frame, and the warning light is electrically connected to the pressure sensing unit.

[0010] Preferably, a plurality of lighting lamps are installed on the upper end surface of the shell along its circumferential direction.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model adopts a driving gear and a driven gear structure to make the SMT patch rotate intermittently, so as to avoid the SMT patch falling off due to excessive speed caused by excessive force during manual rotation, thereby achieving precise adjustment of the rotation of the SMT patch.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 4In this embodiment, a measuring device for SMT patch processing is provided, including a base 1 and a limit frame 2. A shell 11 is installed on the upper end surface of the base 1, and an adjusting motor 12 is installed at the bottom of the shell 11. A driving gear 13 is installed at the output end of the adjusting motor 12. The driving gear 13 is an incomplete gear structure. A driven gear 14 meshing with the driving gear 13 is installed on the right side of the driving gear 13. A fixed cavity 15 is installed on the upper end surface of the driven gear 14. An adjusting screw 16 is rotatably installed on the left end surface of the fixed cavity 15 through a bearing. A handle is installed on the right end surface of the adjusting screw 16. An adjusting slider is screwed onto the outer wall, and a limit frame 2 is installed on the upper end surface of the adjusting slider. When working, the SMT patch is placed in the limit frame 2, and the handle is turned to drive the adjusting screw 16 to rotate, thereby controlling the limit frame 2 to move inward to clamp and fix the SMT patch, which is convenient for detecting the SMT patch. The adjusting motor 12 is started to drive the active gear 13 to rotate, and the active gear 13 drives the driven gear 14 to rotate intermittently, which is convenient for rotating the SMT patch to avoid the SMT patch falling off due to excessive force and excessive speed during manual rotation, and the rotation cannot be accurately adjusted.

[0021] A control panel 17 is installed on the front end surface of the base 1. The control panel 17 is electrically connected to the regulating motor 12. When working, a PLC program is written in the control panel 17 to control the operation of each device.

[0022] The inner side end of the limiting frame 2 is provided with a positioning groove 18, which is a square structure. When working, the SMT patch is placed in the positioning groove 18, so as to perform preliminary positioning processing on the SMT patch.

[0023] A plurality of pressure sensing units 19 are installed from top to bottom on the inner end of the positioning groove 18, and a warning light 21 is installed on the outer end face of the limit frame 2. The warning light 21 is electrically connected to the pressure sensing unit 19. When the limit frame 2 clamps the SMT patch, the pressure sensor senses the pressure signal of the left and right side walls of the SMT patch, and controls the warning light 21 to light up, so as to prevent the limit frame 2 from pressing the SMT patch too much when the handle is turned manually, causing damage to the side wall of the SMT patch.

[0024] The upper end surface of the fixing cavity 15 is symmetrically mounted with an L-shaped frame 22, and the upper end surface of the L-shaped frame 22 is mounted with a sponge pad 23. When the limiting frame 2 is loosened during operation, the SMT patch is deflected and falls on the sponge pad 23, thereby providing shock-absorbing protection for the SMT patch.

[0025] A plurality of lighting lamps 24 are installed on the upper end surface of the housing 11 along its circumferential direction. When in operation, the lighting lamps 24 provide supplementary light to the SMT patches, thereby ensuring the detection effect of the SMT patches.

[0026] During specific work, the SMT patch is placed in the limit frame 2, and the handle is turned to drive the adjusting screw 16 to rotate, thereby controlling the limit frame 2 to move inward to clamp and fix the SMT patch, which is convenient for testing the SMT patch. The adjusting motor 12 is started to drive the active gear 13 to rotate, and the active gear 13 drives the driven gear 14 to rotate intermittently, which is convenient for rotating the SMT patch to avoid the SMT patch falling off due to excessive force and excessive speed during manual rotation, and the rotation cannot be accurately adjusted.

[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
