Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing equipment, and in particular to a clamping frame. Background Technology

[0002] In circuit board manufacturing, clamping frames are common tools used to hold and fix circuit boards, facilitating their transport and production. To accommodate the production of circuit boards of different sizes, clamping frames typically include fixed and sliding frame bars to adjust the size of the clamping area. To improve production efficiency, two clamping areas are usually designed, and the size of both areas can be adjusted simultaneously by adjusting the sliding frame bars. For example, patent application number 202421239773.0 discloses a clamping frame that adjusts the size of the left and right clamping areas by adjusting the up and down position of the sliding frame bars. However, while this type of clamping frame meets most automated production needs, it still has limitations. Because the left and right clamping areas are adjusted simultaneously and by the same amount, it can only produce circuit boards of the same size at the same time and cannot meet the need to produce circuit boards of different sizes simultaneously. Utility Model Content

[0003] To overcome the above problems, this utility model provides a clamping frame. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] A clamping frame includes an upper frame strip and a lower frame strip, which are fixedly connected at both ends by side frame strips to form a frame structure. A fixed frame strip is provided between the upper and lower frame strips to divide the frame into left and right plate placement areas. Sliding grooves are provided at both ends of the upper and lower frame strips, and sliding members are slidably disposed within each sliding groove. A sliding locking structure is provided between the sliding groove and the sliding member to lock / unlock the sliding member.

[0019] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of "a clamp frame" of this utility model is provided in conjunction with the accompanying drawings.

[0020] See Figure 1 and Figure 2 In this embodiment, the clamping frame includes an upper frame strip 100 and a lower frame strip 101. The upper frame strip 100 and the lower frame strip 101 are fixedly connected at both ends by a side frame strip 102 to form a frame structure. A fixed frame strip 103 is provided between the upper frame strip 100 and the lower frame strip 101 to divide the left and right plate-laying areas. The fixed frame strip 103 is preferably perpendicularly connected to the midpoint of the upper frame strip 100 and the lower frame strip 101. Sliding grooves 104 are provided at both the left and right ends of the upper frame strip 100 and the lower frame strip 101. Sliding members 105 are slidably disposed in the sliding grooves 104. A sliding locking structure is provided between the sliding grooves 104 and the sliding members 105 to lock / unlock the sliding. Component 105; The sliding component 105 in the sliding groove 104 at the left end of the upper frame strip 100 and the lower frame strip 101 is fixedly connected by the left sliding frame strip 106. The left sliding frame strip 106 slides left and right along the sliding groove 104 through the sliding component 105 to move away from / close to the fixed frame strip 103; The sliding component 105 in the sliding groove 104 at the right end of the upper frame strip 100 and the lower frame strip 101 is fixedly connected by the right sliding frame strip 107. The right sliding frame strip 107 slides left and right along the sliding groove 104 through the sliding component 105 to move away from / close to the fixed frame strip 103; The left sliding frame strip 106, the right sliding frame strip 107 and the fixed frame strip 103 are all provided with a plate clamping mechanism 108.

[0021] In use, the left sliding frame 106 and the right sliding frame 107 are adjusted to move closer to / away from the fixed frame 103 to independently adjust the size of the left and right clamping areas. Then, the circuit board is clamped and fixed by the clamping mechanism 108 on the left sliding frame 106, the right sliding frame 107 and the fixed frame 103. Circuit boards of different sizes can be clamped and fixed in the left and right clamping areas respectively, which can meet the needs of clamping and fixing circuit boards of different sizes at the same time for production.

[0022] See further Figure 3 and Figure 4 In this embodiment, the sliding groove 104 is provided with a tubular protrusion 109, and the sliding member 105 is provided with an arc-shaped groove 110. The arc-shaped groove 110 cooperates with the tubular protrusion 109, and the sliding member 105 slides along the tubular protrusion 109 through the arc-shaped groove 110 to slide stably in the sliding groove 104, thereby improving the sliding stability of the left sliding frame 106 and the right sliding frame 107.

[0023] See further Figures 2-4 In this embodiment, the sliding locking structure includes a fixed rack 111 and a sliding toothed plate 112. The fixed rack 111 is fixedly disposed on the sliding groove 104, and the sliding toothed plate 112 is slidably disposed on the sliding member 105. An elastic member 113 is disposed between the sliding toothed plate 112 and the sliding member 105. The elastic member 113 is preferably a spring. The elastic member 113 has the tendency to drive the sliding toothed plate 112 to slide closer to and engage with the fixed rack 111 in order to lock the sliding member 105. The sliding toothed plate 112 includes an abutment block 114. When the abutment block 114 is subjected to force, it will drive the sliding toothed plate 112 to compress the elastic member 113 and move away from the fixed rack 111 in order to unlock the sliding member 105. In use, for example in an automated production process, the abutment block 114 is pressed by a robotic arm or a mechanical unlocking component to unlock the sliding component 105. After that, the position of the left sliding frame 106 / right sliding frame 107 is adjusted. Once the position is adjusted, the pressure on the abutment block 114 is released. Under the action of the elastic component 113, the sliding toothed plate 112 slides closer to and engages with the fixed toothed plate 111.

[0024] More specifically, in this embodiment, the sliding member 105 is provided with a locking groove 115 facing the fixed rack 111, and the sliding toothed plate 112 is disposed in the locking groove 115. An elastic member 113 is disposed between the bottom plate 116 of the locking groove 115 and the sliding toothed plate 112. The shape of the locking groove 115 and the shape of the sliding toothed plate 112 are the same, both being "7" shaped, so that the sliding toothed plate 112 can slide stably along the locking groove 115 to approach / move away from the fixed rack 111. Furthermore, for ease of disassembly and maintenance, the bottom plate 116 of the locking groove 115 is detachably fixedly connected to the sliding member 105.

[0025] See further Figure 2 In this embodiment, the clamping mechanism 108 includes a clamping plate 1081 and a clamping strip 1082. The clamping strip 1082 is fixedly mounted on the left sliding frame 106, the right sliding frame 107, and the fixed frame 103. The clamping plate 1081 is rotatably mounted on the left sliding frame 106, the right sliding frame 107, and the fixed frame 103. A torsion spring 1083 is provided between the clamping plate 1081 and the left sliding frame 106, the right sliding frame 107, and the fixed frame 103. The torsion spring 1083 has a tendency to drive the clamping plate 1081 to rotate to press against the clamping strip 1082. The clamping plate 1081 is provided with an opening clamping surface. When the opening clamping surface is subjected to force, it drives the clamping plate 1081 to rotate away from the clamping strip 1082, so as to open the clamp to insert / remove the circuit board and close the clamp to clamp the circuit board.
