Description

Technical Field

[0001] The utility model relates to the technical field of board transportation, in particular to a tray for board transportation. Background Art

[0002] A board is a kind of printed circuit board, abbreviated as PCB board, on which electronic components such as chips, switch interfaces, and connectors are usually installed. After the final inspection step of the board, multiple boards need to be installed in a collecting board box, and then the collecting board box is neatly placed on a tray. The collecting board box is wound and fixed on the tray through a plastic film, and then the tray is fork-lifted for transportation and transfer.

[0003] In practical applications, the existing trays for board transportation still have the following problems: First, most of the existing trays for board transportation lack shock-absorbing structures. During the transportation process when the tray is fork-lifted, the boards on the collecting board box are very easy to oscillate up and down with the tray. During the up-and-down oscillation process, a large impact force will be generated on the boards, resulting in the problem that the main board is easily damaged during transportation; Second, the fixing method of winding and fixing the collecting board box on the tray through a plastic film is relatively troublesome, resulting in a long time-consuming for the transportation and transfer of the boards and poor practicability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tray for board transportation aiming at the above deficiencies, which can not only shock-absorb the boards during transportation and avoid the problem of board damage caused by excessive impact force during the up-and-down oscillation of the tray, but also fix the collecting board box on the tray more conveniently, shorten the time for the transportation and transfer of the boards, and have better practicability.

Detailed implementation manners

[0018] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the tray for transporting board cards includes a base 1 and a plurality of support feet 11 arranged at the bottom of the base 1. It is characterized in that: a tray 2 arranged above the base 1, a plurality of shock-absorbing structures used to connect the base 1 and the tray 2, clamping plates 3 symmetrically arranged on the left and right of the tray 2, a fixing plate 4 arranged between the two clamping plates 3, and a clamping drive structure used to drive the clamping plates 3 to approach or move away from the fixing plate 4, and the bottom end of the fixing plate 4 is fixed on the tray 2.

[0019] During use, place the board card box on the tray 2 between the clamping plates 3 and the fixing plate 4, and drive the clamping plates 3 to approach the fixing plate 4 through the clamping drive structure to clamp and fix the board card box between the clamping plates 3 and the fixing plate 4; when the forklift forks between adjacent support feet 11 and holds the base 1 and moves forward, through a plurality of shock-absorbing structures arranged between the base 1 and the tray 2, shock absorption is provided above the tray 2 to prevent the board card box from generating large up-and-down oscillations, avoiding the problem of damage to the board card due to excessive up-and-down shock impact; the utility model can not only shock-absorb the board card during transportation, avoiding the problem of damage to the board card due to excessive up-and-down shock impact of the tray, but also fix the board card box on the tray more conveniently, shortening the time for transporting and transferring the board card, and having better practicability.

[0020] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a groove 12 is arranged on the base 1, and the tray 2 is connected to slide up and down in the groove 12. The shock-absorbing structure includes four groups of shock-absorbing components arranged at equal intervals in the groove 12; in this embodiment, the tray 2 is shock-absorbed by four groups of shock-absorbing components, and the shock-absorbing effect is better.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, any one group of the shock absorption components includes a cylindrical hollow seat body 61 fixed to the bottom of the groove 12, a shock absorption seat 62 slidably connected up and down in the cylindrical hollow seat body 61, a plug 63 arranged at the top end of the cylindrical hollow seat body 61, a sliding column 64 fixed to the bottom end and arranged on the shock absorption seat 62. The top end of the sliding column 64 passes through the plug 63 and is connected to the support plate 2. A first spring 65 is sleeved on the sliding column 64. The starting end and the ending end of the first spring 65 are respectively connected to the support plate 2 and the plug 63. A plurality of telescopic rods 66 are vertically fixed on the shock absorption seat 62, and a second spring 67 is sleeved on the telescopic rods 66. The two ends of the second spring 67 are respectively connected to the shock absorption seat 62 and the plug 63. In this embodiment, when the support plate 2 vibrates upward along the groove 12, the shock absorption seat 62 slides upward along the cylindrical hollow seat body 61, the sliding column 64 slides upward, the first spring 65 is stretched, and the telescopic rods 66 and the second spring 67 sleeved thereon are compressed. Since the restoring force directions of the first spring 65 and the second spring 67 are opposite, the up-and-down oscillation amplitude of the support plate 2 is reduced. When the support plate 2 vibrates downward along the groove 12, the shock absorption seat 62 slides downward along the cylindrical hollow seat body 61, the sliding column 64 slides downward, the first spring 65 is compressed, and the telescopic rods 66 and the second spring 67 sleeved thereon are stretched. Since the restoring force directions of the first spring 65 and the second spring 67 are opposite, the up-and-down oscillation amplitude of the support plate 2 is reduced, avoiding the problem of damage caused by excessive up-and-down shock impact of bupivacaine.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a chute 21 is arranged on the support plate 2, and a first slider and a second slider are slidably connected in the chute 21. The two clamping plates 3 are respectively fixed on the first slider and the second slider. The clamping driving structure includes a lead screw 51 rotatably connected in the chute 21. Two adjacent sections of external threads with opposite helix directions, i.e., a first external thread and a second external thread, are arranged on the lead screw 51. One end of the lead screw 51 passes through the support plate 2 and is connected to a hand wheel 52. Internal thread holes, i.e., a first internal thread hole and a second internal thread hole, are respectively arranged on the first slider and the second slider opposite to the first external thread and the second external thread. In this embodiment, when the hand wheel 52 is manually rotated, the hand wheel 52 drives the lead screw 51 to rotate. The lead screw 51 is screwed to the first internal thread hole through the first external thread and to the second internal thread hole through the second external thread, so that the first slider and the second slider approach or separate from each other, and thus the two clamping plates 3 approach or separate from the fixed plate 4.

[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a plurality of locking holes 511 are radially formed in the lead screw 51. A connecting plate 53 is provided on one side of the support plate 2. A connecting hole 531 is vertically formed in the connecting plate 53. The connecting hole 531 and the locking hole 511 are plugged through a pin. In this embodiment, by plugging the connecting hole 531 and the locking hole 511 with a pin, the lead screw 51 can be locked to prevent the clamping plate 3 from loosening during the transportation of the board card.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the scope defined by the spirit of the present invention.
