[0033] During the use of the PCB clamping fixture of the present application, by applying force to the pushing portion 212, since the clamping portion 211 and the pushing portion 212 are arranged on the side of the hinge portion 213 close to the clamping area 101, the clamping portion 211 is rotated and opened around the hinge portion 213 under the action of the pushing portion 212, so that the process end of the PCB can be clamped in the clamping area 101 by the clamping unit 200 located at the movable part 120 and the mounting part 110. After the force applied to the pushing portion 212 is removed, the elastic force provided by the elastic member 220 In use, the push part 212 drives the clamping part 211 to rotate and close around the hinge part 213, and the clamping units 200 on the mounting part 110 and the movable part 120 respectively clamp the process ends of the PCB on both sides in the first direction. Since the movable part 120 is set to slide along the first direction, under the action of external force, the clamping unit 200 on the movable part 120 clamps the process end on one side of the PCB away from the mounting part 110. Therefore, the process end on one side of the PCB is driven by the movable part 120 away from the process end on the other side until the PCB is in a straight state as a whole. It can be known from the above use process that when the PCB material used is relatively soft, the present application can adjust the distance between the movable part 120 and the mounting part 110 so that the PCB is in a straight state as a whole.

[0034] In some embodiments of the present invention, the fixture body 100 includes two fixed components 130 spaced apart and arranged in parallel along a second direction, the second direction is spaced apart from the first direction by a certain angle, the movable member 120 is slidably connected to the two fixed components 130 along the first direction, both ends of the mounting member 110 are fixedly connected to the two fixed components 130, and the mounting member 110, the movable member 120 and the two fixed components 130 jointly define a clamping area 101. For example, Figure 1 and Figure 4 As shown, the fixture body 100 includes two fixed components 130 spaced apart and arranged in parallel along the second direction, the second direction is perpendicular to the first direction, the extension direction of the fixed components 130 is the first direction, both ends of the movable part 120 are slidably connected to the two fixed components 130 along the first direction, both ends of the mounting part 110 are fixedly connected to the two fixed components 130, and the mounting part 110, the movable part 120 and the two fixed components 130 jointly define a clamping area 101.

[0035] In one embodiment, the fixing assembly 130 includes a fixing frame bar 131 and a guide rod 132. The fixing frame bar 131 is provided with a first slide groove 133 extending in a first direction. The guide rod 132 is disposed in the first slide groove 133 and is parallel to the first slide groove 133. Both ends of the movable member 120 are slidably connected to the guide rod 132. For example, Figure 1 and Figure 3As shown, the fixed component 130 includes a fixed frame bar 131 and a guide rod 132.

The two sliders 122 are respectively slidably mounted on the guide rods 132 of the two fixed components 130, and the two sliders 122 can both slide in the first slide groove 133 along the first direction.

[0036] It can be understood that when the movable part 120 slides along the first direction, the slider 122 slides in the first direction along the guide rod 132 in the first slide groove 133, and the sliding of the slider 122 is limited by the first slide groove 133 and the guide rod 132, so that the sliding direction of the slider 122 is not easily deviated, thereby reducing the possibility of inconsistent travel of the slider 122 connected to one end of the movable bar 121 relative to the slider 122 connected to the other end when the movable part 120 slides on the fixed component 130.

[0037] In some embodiments of the present invention, the fixture body 100 further includes at least one separator 140, which is spaced between the two fixing components 130 along the second direction, one end of the separator 140 is connected to the mounting component 110, and the movable component 120 is slidably connected to the separator 140 along the first direction. Figure 1 and Figure 4 As shown, the fixture body 100 includes a separator 140, which is spaced and arranged in parallel between two fixed components 130 along the second direction, the extending direction of the separator 140 is the first direction, one end of the separator 140 is fixedly connected to the mounting member 110, and the separator 140 is provided with a second slide groove 141 extending in the first direction, and the movable member 120 also includes a roller, which is connected to the movable bar 121 through a threaded fastener, and the roller is slidably arranged in the second slide groove 141 along the first direction. It can be understood that by providing the separator 140 and the movable member 120 being slidably connected to the separator 140, support is provided for the middle part of the movable member 120; the movable member 120 is slidably connected to the separator 140 in the form of a roller, and the friction between the separator 140 and the movable member 120 is effectively reduced while ensuring the supporting effect.

[0038] In some embodiments, the clamping area 101 is divided into a plurality of sub-clamping areas 101a by a separator 140, and each sub-clamping area 101a is provided with two groups of clamping units, and the two groups of clamping units are arranged on opposite sides of the sub-clamping area 101a in the first direction, each group of clamping units includes at least one clamping unit 200, and each sub-clamping area 101a is used to place a PCB. Figure 1 and Figure 4 As shown, the clamping area 101 is divided into two sub-clamping areas 101a by a separator 140, and each sub-clamping area 101a is correspondingly provided with two groups of clamping unit groups, and the two groups of clamping unit groups are arranged on opposite sides of the sub-clamping area 101a in the first direction, and each group of clamping unit groups includes two clamping units 200, and each sub-clamping area 101a is used to place a PCB. It can be understood that each sub-clamping area 101a can place a PCB, and the process ends of the PCB on both sides of the first direction are clamped by at least one clamping unit 200 respectively.

[0039] In some embodiments of the present invention, Figure 5 As shown, the jig body 100 is provided with an avoidance through hole 150, which corresponds to the clamping unit 200 one by one, and the avoidance through hole 150 can allow the push rod to pass through and push the push part 212. It can be understood that a push rod is provided on the side of the jig body 100 away from the clamping unit 200, and the push rod corresponds to the avoidance through hole 150 one by one. The push rod is connected to a driver. Before clamping the process end of the PCB, the push rod can pass through the avoidance through hole 150 and push the push part 212 under the drive of the driver. Driven by the push part 212, the clamping part 211 can overcome the elastic force of the elastic member 220 and rotate around the hinge part 213 to move away from the clamping area 101, so that the PCB can be placed in or out of the clamping area 101.

[0040] refer to Figure 1 and Figure 4 In some embodiments of the utility model, the mounting member 110 and the movable member 120 are both provided with a first abutting boss 160 protruding into the clamping area 101, and the first abutting boss 160 is used to abut against the side of the PCB away from the clamping portion 211, so as to cooperate with the clamping portion 211 to clamp the process end of the PCB. It can be understood that when the PCB is placed in the clamping area 101, the opposite sides of the thickness direction of the process end of the PCB can respectively abut against the first abutting boss 160 and the clamping portion 211, thereby achieving clamping and fixing of the PCB. By providing the first abutting boss 160 on the mounting member 110 and the movable member 120, the supporting effect of the fixture body 100 on the PCB can be further enhanced.

[0041] In one embodiment, the clamping unit 200 further includes a clamping rod 230, which is connected to the clamping portion 211 and is used to abut against the process end of the PCB. The clamping rod 230 is parallel to the first abutting boss 160 disposed on the same mounting member 110 or movable member 120. Figure 4 and Figure 5As shown, the clamping unit 200 further includes a clamping rod 230, which is connected to the clamping portion 211 and is located at one end of the clamping portion 211 close to the first abutting boss 160. The extension direction of the clamping rod 230 is parallel to the extension direction of the first abutting boss 160 provided on the same mounting member 110 or the movable member 120. It can be understood that when the PCB is located in the clamping area 101, the first abutting boss 160 can support the edge of the process end of the PCB. When the pushing portion 212 drives the clamping portion 211 to rotate around the hinge portion 213 under the elastic force provided by the elastic member 220, the clamping rod 230 rotates accordingly until the outer peripheral surface of the clamping rod 230 abuts against the side of the PCB away from the first abutting boss 160. Since the extension direction of the clamping rod 230 is parallel to the extension direction of the first abutting boss 160, the clamping unit 200 can clamp the process end of the PCB in a wider range.

[0042] In one embodiment, if Figure 1 and Figure 4 As shown, the separator 140 is provided with a second abutting boss 142 protruding into the sub-clamping area 101a, and the second abutting boss 142 is used to abut against the side of the PCB away from the clamping portion 211 to cooperate with the clamping portion 211 to clamp the PCB. It can be understood that by adding the second abutting boss 142 to the separator 140, the supporting effect of the fixture body 100 on the PCB can be further enhanced.

[0043] refer to Figure 2 and Figure 5 In some embodiments of the present invention, the clamping unit 200 further includes a mounting seat 240, which is detachably disposed on the fixture body 100, and the hinged portion 213 is rotatably connected to the mounting seat 240. It can be understood that the hinged portion 213 is rotatably sleeved on the mounting seat 240, and when the pushing portion 212 drives the clamping portion 211 to rotate, the clamping portion 211 rotates around the mounting seat 240, and the mounting seat 240 is detachably connected to the fixture body 100, so when it is necessary to disassemble the clamping unit 200, the staff can remove the clamping unit 200 from the fixture body 100 by disassembling the mounting seat 240.
