[0003] In the prior art, the positioning device of the circuit board generally consists of a carrier platform and a clamp that can be moved laterally at a relative position on the carrier platform. The clamp is moved horizontally to squeeze and clamp the outer wall of the relative position of the circuit board, and the clamp is locked in a position on the carrier platform to achieve clamping and positioning of the circuit board, so as to ensure the stability of the position of the circuit board during subsequent processing.

[0004] However, in the four-point clamping positioning device currently used, two groups of clamps are composed of two to perform self-centering clamping on the outer walls of both sides of the circuit board. In actual use, after one group of clamps clamps and positions the circuit board, the circuit board is already in a relatively fixed state. When the other group of clamps performs self-centering clamping on the circuit board for the second time, the circuit board will be driven to deviate to satisfy the self-centering positioning of the circuit board. This causes the circuit board to slide relative to the previous clamp during the second positioning and clamping process, which can easily cause scratches or wear on the outer wall of the circuit board.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-4 A circuit board positioning device shown in the figure includes a cross track 101 and a clamping clamp 200 that can be moved and locked along the outer wall of the cross track 101 at the four end positions of the cross track 101. The bottom end of the cross track 101 is fixedly connected to a positioning platform 100, and the four corners of the side wall of the positioning platform 100 are fixedly connected to connectors with sinking holes. The positioning platform 100 cooperates with the connectors thereon to facilitate the installation and positioning of the entire positioning device on the processing table, so as to facilitate multi-point use. The clamping clamp 200 includes a clamp seat 201, a cylindrical roller 203 movably arranged inside the installation slot 202, and a locking mechanism. The locking mechanism is arranged between the clamp seat 201 and the cross track 101. The locking mechanism is used to lock the position of the clamp seat 201 on the cross track 101. The position of the clamp 200 on the cross track 101 can be locked by the locking mechanism, so that the clamp 200 can stably clamp the side wall of the circuit board. The clamp seat 201 is provided with a mounting slot 202 on the side facing the center of the cross track 101. The cylindrical roller 203 can rotate inside the mounting slot 202, and the outer wall of the cylindrical roller 203 extends to the outside of the clamp seat 201. In order to increase the protection performance, the outer wall of the cylindrical roller 203 can be covered with a rubber sleeve for protection. A carrying plate 102 is fixedly connected to the middle of the top of the cross track 101, and the carrying plate 102 is used to carry the circuit board;

[0024] In the above embodiment, the two clamping pliers 200 at relative positions on the cross track 101 move toward each other to clamp the two side walls of the circuit board placed on the carrier plate 102. While the outer wall of the cylindrical roller 203 in the clamping pliers 200 is in contact and squeezed with the outer wall of the circuit board for clamping, the cylindrical roller 203 is rotatable so that the other two clamping pliers 200 at relative positions on the cross track 101 move toward each other to perform secondary positioning and clamping of the circuit board. In the process of driving the circuit board to move horizontally, the cylindrical roller 203 on the clamp seat 201 in the initial clamping can be driven to rotate, thereby preventing the circuit board from being scratched due to relative movement with the clamping pliers 200 during the lateral movement process, thereby achieving the effect of enhancing the protection of the circuit board during the clamping process.

[0025] In a preferred embodiment, the locking mechanism includes a translation slider 103 fixedly connected to the bottom end of the clamp seat 201, and the translation slider 103 can move linearly along the outer wall of the cross track 101. A threaded clamp 104 is threadedly inserted at the top of the translation slider 103. The bottom end of the threaded clamp 104 penetrates the inner wall of the translation slider 103 and can contact the outer wall of the cross track 101. The threaded clamp 104 is located on the side of the clamp seat 201 away from the center of the cross track 101. A linear groove 105 connected to the inner cavity of the cross track 101 is provided on the side wall of the cross track 101. The bottom of the translation slider 103 is bent inwardly and extends to the inside of the linear groove 105. When the clamp 200 moves along the outer wall of the cross track 101 During the movement, since the bottom of the translation slider 103 is movably engaged with the inner side of the linear groove 105, a limiting guide is formed between the translation slider 103 and the cross track 101, so that the translation slider 103 can keep the stability of the clamping clamp 200 moving horizontally on the cross track 101. Moreover, when the threaded clamp 104 rotates clockwise and moves downward through the rotation and thread pressing action, the end face of the threaded clamp 104 squeezes the surface of the cross track 101, so that the translation slider 103 and the cross track 101 are locked by the extrusion force, and the clamping clamp 200 is positioned on the cross track 101. The operation is simple, and the unlocking is convenient and easy to use.

[0026] Among them, a mounting shaft 106 is fixedly connected to the middle part of the inner cavity of the cross track 101, and two rotatable transmission gears 107 are arranged on the outer wall of the mounting shaft 106 from top to bottom. Two rack plates 108 are arranged symmetrically on both sides of each transmission gear 107, and the ends of the rack plates 108 are fixedly arranged with the translation sliders 103 at corresponding positions, wherein the two horizontal groups of rack plates 108 are respectively meshed with the transmission gears 107 at the upper position, while the two rack plates 108 located in the longitudinal direction are respectively meshed with the transmission gears 107 at the lower position, and the ends of the rack plates 108 at corresponding positions are respectively connected to the bottom of the translation slider 103 at corresponding positions through fixing parts to keep the adjacent two fixed, so that the movement of the rack plates 108 at the corresponding positions can drive the translation slider 103 connected thereto to move, and two groups of straight lines are arranged in a cross shape inside the cross track 101. Slide rods 109, each group of linear slide rods 109 is two and arranged in parallel on both sides of the transmission gear 107, the outer walls of the linear slide rods 109 are movably plugged with the middle of the rack plate 108 at the corresponding position, and the rack plate 108 can be carried by the linear slide rods 109 while allowing the rack plate 108 to move axially along the linear slide rods 109 to keep the rack plate 108 moving smoothly, and then the two centrally symmetrical rack plates 108 are respectively meshed with the same transmission gear 107, so that when one of the rack plates 108 moves, the other rack plate 108 can be driven to move synchronously in the opposite direction through the transmission action of the transmission gear 107, so that the two clamping clamps 200 at relative positions on the cross track 101 can be driven to move synchronously toward each other, thereby achieving self-centering clamping of the opposite sides of the circuit board, making the clamping and positioning of the circuit board more accurate and the operation more convenient.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
