[0002] During the production and processing of products, the grasping and moving of products are inevitably involved. For example, during the visual inspection of PCB boards, the PCB boards are prepared by the upstream process and then sent to the visual inspection equipment for appearance inspection. Generally, the PCB boards are placed on the visual inspection equipment manually, with low automation. Manual material taking and placing are required, increasing labor costs.

[0003] The purpose of the utility model is to provide a double-sided clamping device that can overcome the above-mentioned drawbacks. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a double-sided clamping device. By setting two groups of clamping mechanisms on the left and right, the stable clamping and preliminary positioning of PCB boards and the like can be automatically achieved. Through the roller structure, smooth connection with the upstream and downstream supports can be realized, improving the versatility and compatibility of the device.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: providing a double-sided clamping device, which includes a mounting frame, two groups of clamping mechanisms arranged on the mounting frame, a clamping driving mechanism capable of driving the two clamping mechanisms to approach or separate, a roller structure, and a roller driving mechanism. Define the two groups of clamping mechanisms as the left clamping mechanism and the right clamping mechanism respectively. Each clamping mechanism includes a clamping plate and a row of clamping heads arranged at the upper end of the clamping plate; the clamping driving mechanism includes a clamping driving motor, a gear, a left rack, and a right rack. The power output end of the clamping driving motor is connected to the gear, and the gear is simultaneously meshed with the left rack and the right rack. The left clamping mechanism is fixedly connected to the left rack, and the right clamping mechanism is fixedly connected to the right rack;

[0006] The roller structure includes a row of rollers arranged at intervals, and both ends of the rollers are rotatably connected to the left and right ends of the mounting frame respectively; the roller driving mechanism includes a roller driving motor, a lower roller, a plurality of upper rollers, and a transmission belt. Each upper roller is installed at one end of the roller, and the transmission belt is simultaneously sleeved on the lower roller and all the upper rollers. The power output end of the roller driving motor is connected to the lower roller and drives it to rotate.

[0007] Further, the clamping head is a clamping head made of a soft material.

For example, the PCB board is pushed into the detection range of the vision detection device. Therefore, the present utility model can automatically realize the stable clamping and preliminary positioning of PCB boards and the like by arranging two sets of left and right clamping mechanisms, and can be smoothly connected with the upstream and downstream supports through the drum structure, improving the versatility and compatibility of the device;

[0013] Furthermore, both the left and right clamping mechanisms of the present utility model include a clamping plate and a row of clamping heads arranged at the upper end of the clamping plate.

[0022] Embodiment: A double-sided clamping device, as Figures 1 to 3 shown, the double-sided clamping device includes a mounting frame 1 and two sets of clamping mechanisms provided on the mounting frame, a clamping drive mechanism 6 capable of driving the two clamping mechanisms to approach or separate from each other, a drum structure 2 and a drum drive mechanism 3. Define the two sets of clamping mechanisms as a left clamping mechanism 4 and a right clamping mechanism 5 respectively. Each clamping mechanism includes a clamping plate 41 and a row of clamping heads 42 provided at the upper end of the clamping plate; the clamping drive mechanism 6 includes a clamping drive motor 61, a gear 62, a left rack 63 and a right rack 64. The power output end of the clamping drive motor is connected to the gear, and the gear is simultaneously meshed with the left rack and the right rack. The left clamping mechanism is fixedly connected to the left rack, and the right clamping mechanism is fixedly connected to the right rack;

[0023] The drum structure includes a row of drums 21 arranged at intervals, and both ends of the drums are rotatably connected to the left and right ends of the mounting frame respectively; the drum drive mechanism 3 includes a roller drive motor 31, a lower roller 32, a plurality of upper rollers 33 and a transmission belt 34. Each upper roller is installed at one end of the drum, and the conveyor belt is simultaneously sleeved on the lower roller and all the upper rollers. The power output end of the roller drive motor is connected to the lower roller and drives it to rotate.

[0024] Both the left and right clamping mechanisms of this device include a clamping plate and a row of clamping heads provided at the upper end of the clamping plate. When clamping the product with multiple clamping heads, the acting force can be balanced and dispersed, avoiding damaging the product. Especially for flat products, the effect is more obvious and more necessary.

[0025] In this embodiment, the clamping head is a clamping head made of a soft material, such as hard plastic, bakelite, etc., which plays a role of buffering and protection to avoid damaging the product.

[0026] In this embodiment, the left end of the left rack is fixedly connected to the clamping plate of the left clamping mechanism through the left slider 631, and the right side of the right rack is connected to the clamping plate of the right clamping mechanism through the right slider 641; a slide rail 11 is provided on the upper surface of the mounting frame, and the left slider and the right slider cooperate with the slide rail and can move along the slide rail.

[0027] In this embodiment, the drum and the clamping head are arranged at intervals, and the clamping head is located between adjacent drums and is higher than the drums in position.

[0028] In this embodiment, a groove 43 is provided at the lower end of the clamping plate, and both sides of the lower end of the clamping plate are slidably connected to the slide rail through the left slider or the right slider respectively, ensuring the stability of the translation process of the clamping plate.

[0029] The working principle and process of the present utility model:

[0030] The product supported upstream (such as a PCB board) is conveyed onto the drum and moves with the drum. Then, the clamping drive motor drives the gear to rotate. Through the meshing of the gear with the left rack and the right rack, and then through the cooperation of the left and right sliders with the slide rail, the left and right clamping mechanisms are driven to approach and clamp the product. For example, the PCB board is pushed into the detection range of the vision detection device, and then it can be detected by the vision detection unit (such as an industrial camera); after the detection is completed, the clamping drive motor rotates in the reverse direction to make the left and right clamping mechanisms move away and release the product.

[0031] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structures made by using the content of the specification and drawings of the present utility model, directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
