[0026] like Figures 1 to 5 As shown, this utility model embodiment provides a clamping device, including a platform 100, a sliding member 200, a clamping member 300, a lead screw 500, and an operating member 600.

[0027] Two sliding members 200 are horizontally spaced and slidably disposed on the shelf 100, and the upper end of the sliding member 200 is connected to a clamping member 300 through a connecting structure 400.

[0028] Specifically, the connection structure 400 includes a connector 410 and a connection hole 420. One of the sliding member 200 and the clamping member 300 is provided with the connector 410, and the other is provided with a connection hole 420 that corresponds to and is adapted to the connector 410. In this embodiment, the connector 410 is preferably provided at the lower end of the clamping member 300, and the connection hole 420 is provided on the sliding member 200. Furthermore, the connector 410 can be inserted into or removed from the connection hole 420. Through the plug-in design of the connector 410 and the connection hole 420, the installation and disassembly process of the clamping member 300 and the sliding member 200 is simple and efficient, which facilitates the maintenance of the clamping device and the replacement of clamping members 300 of different specifications.

[0029] It should be noted that the shape of the connecting hole 420 can be circular, rectangular, etc. In this embodiment, it is preferably circular, and the connecting hole 420 is set to two at intervals along the length direction of the clamping member 300. Of course, it can also be set to more than two according to actual design requirements, so as to ensure the stability of the clamping member 300 installation.

[0030] The two sliders 200 can move linearly toward or away from each other to drive the two clamping members 300 to move closer or further apart. That is, the two sliders 200 can move linearly individually or synchronously to clamp or release the motherboard or chip.

[0031] In one embodiment, such as Figure 1 and 2 As shown, the clamping member 300 includes a first clamping plate 310 for clamping the motherboard and a second clamping plate 320 for clamping the chip. The second clamping plate 320 is disposed at the lower end of the first clamping plate 310. The opposite sides of the second clamping plates 320 on the two clamping members 300 extend in the opposite direction of the two clamping members and are exposed relative to the corresponding first clamping plate 310 so as to clamp the chip which is relatively small in size to the motherboard.

[0032] like Figure 4 As shown, in order to improve the convenience and selectivity of chip clamping operations, right-angle notches 321 are provided on the opposite surfaces of the second clamping plates 320 on the two clamping members 300. The openings of the right-angle notches 321 on the two second clamping plates 320 are arranged opposite each other, so that the chip can be clamped diagonally, thereby improving the efficiency of chip adhesive removal.

[0033] like Figure 4 As shown, in order to improve the stability of clamping the motherboard, slots 312 are provided on opposite sides of the first clamping plate 310 on the two clamping members 300. Multiple slots 312 are provided at intervals along the length direction of the first clamping plate 310. The number of slots 312 is set according to the actual design requirements. In this embodiment, five are preferred. That is, the motherboard is clamped on the side by the slots 312, which can prevent the motherboard from falling off and facilitate the desoldering or soldering of the motherboard.

[0034] like Figure 4As shown, the connector 410 includes a fastener 411 and a positioning pin 412. The first clamping plate 310 has a through hole 311 extending through its upper and lower ends. The through hole 311 extends downward through the second clamping plate 320. The upper end of the positioning pin 412 abuts against the lower end of the second clamping plate 320 and corresponds to the through hole 311. The diameter of the positioning pin 412 is larger than the diameter of the through hole 311. Furthermore, the fastener 411 includes a rod portion 4111 and a head 4112 disposed at the upper end of the rod portion 4111. The rod 4111 passes through the through hole 311 from top to bottom and is threaded to the positioning pin 412. The head 4112 abuts against the upper end of the first clamping plate 310. Specifically, the fastener 411 is a screw. During assembly, the positioning pin 4112, the first clamping plate 310, and the second clamping plate 320 can be assembled together by passing the rod 4111 of the fastener 411 through the through hole 311 and connecting it to the positioning pin 412, and by rotating the head 4112. The assembly is convenient and facilitates subsequent maintenance and replacement.

[0035] In one embodiment, such as Figure 3 As shown, the shelf 100 includes a body 110, wherein two sliding grooves 111 are provided at intervals along the movement direction of the slider 200 at the upper end of the body 110. The two sliders 200 are respectively slidably disposed in the two sliding grooves 111. The arrangement of the sliding grooves 111 can reduce the space occupied and make the overall structure more compact.

[0036] Furthermore, the upper ends of the inner sidewalls corresponding to both ends of the slide groove 111 and the slider 200 extend inward to form a limiting wall 112. The upper end of the slider 200 is lower than the lower end of the limiting wall 112. The upper end of the slider 200 is provided with an upwardly protruding first protrusion 210. The two ends of the first protrusion 210 are slidably connected to the corresponding limiting wall 112. That is, through the cooperation between the slide groove 111 and the two ends of the slider 200, as well as between the limiting wall 112 and the first protrusion 210, the slider 200 is limited to prevent the slider 200 from deviating or jumping.

[0037] In one embodiment, such as Figure 1 and 2As shown, the shelf 100 also includes a glass panel 120 disposed on the upper end of the main body 110. The glass panel 120 is made of tempered glass or quartz glass and other high-temperature resistant glass. The surface of the glass panel 120 is smooth, making it easy to wipe and clean, and preventing the accumulation of debris from affecting the operation of the device. The glass panel 120 is provided with a strip hole 121 that is opened along the movement direction of the sliding member 200 and corresponds to the positioning pin 412. The upper end of the first protrusion 210 is provided with a second protrusion 220. The second protrusion 220 passes through the strip hole 121 and its upper end is higher than the upper end of the glass panel 120. The connecting hole 420 is opened on the upper end of the second protrusion 220. The strip hole 121 has a guiding function, can limit the movement distance of the sliding member 200, and also has a foolproof function, allowing the operator to operate it.

[0038] In one embodiment, such as Figure 3 As shown, each of the two slide grooves 111 is provided with a lead screw 500. The lead screw 500 is set along the movement direction of the sliding member 200. The lead screw 500 is threadedly connected to the sliding member 200. The lead screw 500 can rotate around its axis to drive the sliding member 200 to move along its axis. That is, by rotating the two lead screws 500, the two clamping members 300 can be driven to move, clamping or releasing the motherboard or chip.

[0039] In one embodiment, such as Figure 1 As shown, the opposite ends of the two lead screws 500 penetrate the body 110 and are exposed externally. An operating element 600 is provided at the exposed end of each lead screw 500. The operating element 600 is preferably a knob. A silicone sleeve 610 is fitted onto the operating element 600. The silicone sleeve 610 is elastic, which increases the surface friction of the operating element 600, preventing hand slippage during adjustment. Furthermore, the soft touch of the silicone sleeve 610 enhances the comfort of the operator and improves the user experience. It should be noted that in some embodiments, a motor can also be used to drive the exposed ends of the lead screws 500.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
